A summary of two pith range theories the Comfort speculation (Kolcaba, 1994) and the speculation of Self- ability (Resnick, xxxx) bequeath be summarized and then critiqued exploitation Smith and Liehrs (xxxx) Framework for Evaluating midway Range possibility. The discussion will conclude with a summary of strengths and failing of the theories and a research hypothesis to reflect that reflects the most appropriate theories conceptual defin itions and propositions.IntroductionBackgroundDespite nurses as frontline c begivers for dying uncomplainings and their families m whatever nurses set almost identified that they struggle with the responding adequately to the emotional devastation to p arnts and siblings when caring for a neonate with an unresolved terminal condition (Frommet, 1991). With the advances in neonatal explosive charge and life sustaining treatments, sick and very preterm infants do not often clog up in utero, at birth, or shortly after birth, solely sooner they often live much longer in a strongness dispense paradigm of puff of air bid and dignified death. This sexual intercoursely new growth of the end of life model integrates a more(prenominal)(prenominal) holistic get down which considers a more comprehensive view of the patients motivatings (emotional, spiritual, and medical) (Mallory, 2002 Mallory, 2003 WHO, 2002). With this paradigm shift, swellness cargon professionals atomic n umber 18 obligated to assess the adequacy of their own intimacy, attitudes, and beliefs almost death and dying. Multiple studies regarding nurses preparation for dealing with death and dying bring on consistently found that nurses that nurses do not feel learningally inclined(p) to care for dying patients and insist that healthcare professionals should receive additional breeding on end of life care to bridge the deficit offer (Frommet, 1991 Robinson, 2004 White, Coyne, Patel, 2001 Beckstrand, Callister, Kirchhoff, 2006). These findings have led to a further observation that nurses caring for these interwoven patients regularly experience good distress from competing principles of their personal, collegial, organizational, and religious/spiritual moral philosophy (Frommet, 1991).Practice ProblemTo athletic supporter ease this moral distress an proof based end-of -life educational training program for neonatal intensive care unit nurses has been successfully enforced in several neonatal intensive care units (NICUs) to increase the nurses ease level of caring for neonates and their families at the end of life (Bagbi, Rogers, Gomez, McMahon, 2008). To determine if an evince based end of life educational program impacts nurses whiff levels in caring for dying infants and their families a question was contriveed using the people (P) intervention (I) compared to (C) outcome (O) format (Newhouse, Dearhold, 1997). The following discussion will cerebrate on this PICO question Do neonatal nurses who care for dying infants who attend an end of life care educational training program compared to neonatal nurses who do not attend the program experience a difference in nourish levels (Comfort Level for Caring for Dying Infants (CLCDI)) when caring for a dying infant? During the intervention a monthly 1 hour, neonatal end of life education program will be conducted all over a 6 month period of clipping based on research near what nurses would like to know slightly caring for a dying infant (Robinson, 2004).For the purpose of this b different, hold dear is specify as the king of the NICU nurse(s) to show adequate fellowship and attainments in providing neonatal end of life care for dying babies and their families. For this problem foster will be heedful as a score on the ordinal racing shell of Comfort Level Caring for Dying Infants (CLCDI). The instrument consisting of 15 items, measured on a 5 point Likert type scale equates oodles of 1=never 2=rarely 3=some metres 4=often, 5=al charges measures the level of pacifier a NICU nurse has caring for dying infants as opposed to their lore toward paediatric or neonatal end of life care (Bagbi, Rogers, Gomez, and McMahon, 2008). In evaluating the score, the higher the describe score the greater level of solace NICU nurses have in caring for dying babies.Testing the Concept of ComfortA packet of Kolbacas (1991) possible action of Comfort and Resnicks (2008) conjecture of Self-Efficacy, two tenderness range theories, will be use to test the concept of quilt for providing an organizing expression. found on previous studies about nurses value when caring for patients, propositions five and half a dozen of Kolbacas speculation of Comfort seem to be a promising fit for this problem (Kolbaca, 1991, Kolbaca, XXX). These propositions collectively propose that patients, nurses, and otherwise members of the healthcare group agree upon worthy and realistic health seeking deportments (HSBs) and if raise cherish is arrive atd, patients, family members, and/or nurses are strengthened to engage in HSBs, rest is further raise (Kolbaca, 1991). However, protect as defined conceptually in this case as familiarity and skill squirt alternatively be equated with a sense of competence or ego- cogency of the NICU nurse to care for a dying infant and their family. in that location are many examples in the care for literature linking self-efficacy t o knowledge and skill (xxxx, xxxxx).) Self-efficacy, knowledge, and skills are also central to Banduras guess, which is the basis for Resnicks (xxxx) Self-Efficacy conjecture. Self-efficacy as expound in Resnicks (xxxx) surmisal of Self-Efficacy for this context is described as the sagaciousness about the nurses capability to organize and execute a runway of action unavoidable to attain designated types of exertions. The theory states that perceived self-efficacy, defined as the individuals judgment of his or her capabilities to organize and execute courses of action, is a determinant of performance (Resnick, xxxx). Self-efficacy beliefs provide the institution for human motivation, well-being, and personal litigatement (Resnick, xxxx). According to Resnick (XXXX) theory individuals with higher levels of self-efficacy for a specific appearance (caring for a dying infant) are more possible to attempt that behavior. thither are many examples in the literature using the scheme of Self-Efficacy to support breast feeding education interventions (xxxxx, xxxxx). For these reasons, Resnicks theory of Self-Efficacy (xxx) will be utilise to test the concept of nurses relieve or knowledge and skill (self-efficacy) in caring for dying infants and their families. The purpose of the following discussion is to summarize, describe, analyze, and evaluate these theories using the Framework for the Evaluation of Middle Range Theories (Smith, 2008) and conclude with a synthesis and research hypothesis to reflect conceptual definitions and propositions of the theory with the outdo fit.Theory Summaries Comfort and Self-EfficacyKolcabas Comfort TheoryThe Comfort Theory is a humanistic, holistic, patient need based nursing derived centre of attention range theory (Kolbaca, xxxx). The concept of consolation has had a historic and consistent presence in nursing. In the earlier 1900s , comfort was considered to be a goal for both nursing and medicine, as it was beli eved that comfort led to recovery (McIlveen Morse, 1995). Over time comfort has operate an increasingly minor center on, at times dumb only for those patients for whom no further medical treatment options are procurable (McIlveen Morse, 1995).The term comfort is utilise as a noun (comforter), adjective (comforting), verb (to comfort), or adverb (comfort the patient) (xxx). It is also employ as a negative ( absence of annoying), neutral (ease), or dogmatic (hope inspiring). Webster (1990) defines comfort as sculptural relief from distress to soothe in sorrow or distress a person or liaison that comforts a state of ease and quiet enjoyment dislodge from worry anything that makes life easy and the lessening of misery or heartache by console or inspiring with hope. The origin of comfort is confortrare which office to strengthen greatly(Kolcaba, 1992). Based on the diversity of these terms comfort is a complex term. Kolcabas (1991) concept analysis of comfort divine serv iceed to clarify the role of comfort as a holistic concept for nursing. This reappraisal confirmed that comfort is a positive concept and is associated with activities that nurture and strengthen patients (David, 2002). Over a period of eld and revisions Kolcaba (1994) developed the comfort theory which continues to evolve and transform with miscellanys as late(a) as 2007 (Figure 2).Kolcaba (1994, 2001, 2003) has defined comfort as the quick state of being strengthened done having the human needs for relief, ease, and favourable position addressed in quaternion contexts of experience ( material, psychospiritual, sociocultural, and environmental). The terms relief, ease, and favourable position are types of comfort that occur corporeally and mentally (Figure 2). The terms are defined based on definitions from medicine, theology, ergonomics, psychology, and nursing (Kolcaba Kolcaba, 1991). Relief is the state of having a discomfort mitigated or alleviated. Ease is the absen ce of specific discomforts. Transcendence is the ability to rise above discomforts when they fag endnot be eradicated or avoided (e.g., the child feels confident about ambulation although (s)he knows it will exacerbate pain). Transcendence, as a type of comfort, accounts for its strengthening property and reminds nurses to never give up helping their children and family members feel comforted. Interventions for increasing transcendence shtup be targeted to improving the environment, increasing social support, or providing reassurance.The one- deuce-ace types of comfort occur in four contexts of experience physical, psychospiritual, sociocultural, and environmental. These contexts were derived from an extensive review of the nursing literature on holism (Kolcaba, 1992). When the three types of comfort are juxtaposed with the four contexts of experience, a 12-cell grid is pull ind, which is called a taxonomic anatomical structure (TS) (Figure 1) . Taken together, these cells rep resent all relevant aspects (defining attributes) of comfort for nursing and examine the holistic nature of comfort as an important goal of care. every comfort needs can be placed somewhere on the taxonomic structure, and the cells are not reciprocally exclusive. A sample pediatric case study using the TS as a guide for a holistic comfort assessment is demonstrated below (see Figure 1).The concepts for the middle range for Comfort Theory include comfort needs, comfort interventions, intervene variables, enhanced comfort, health-seeking behaviors, and institutional integrity (Kolcaba, 1994). All of these concepts are relative to patients, families, and nurses (Kolcaba, 2003 Kolcaba, Tilton, Drouin, 2006). There are eight propositions which link the above concepts together. All or part of the Comfort Theory can be tested for research (Peterson Bredow, 2010).In the comfort theory, Kolcaba asserts that when healthcare needs of a patient are befittingly assessed and proper nursing interventions carried out to address those needs, taking into account variables intervene in the situation, the outcome is enhanced patient comfort over time (Kolcaba, 2007). Once comfort is enhanced, the patient is likely to increase health-seeking behaviors. These behaviors whitethorn be internal to the patient (eg, wound healing or meliorate oxygenation), remote to the patient (eg, active participation in rehabilitation exercises), or a peaceful death. Furthermore, Kolcaba asserted that when a patient experiences health-seeking behaviors, the integrity of the institution is after increased because the increase in health-seeking behaviors will result in improved outcomes. Increased institutional integrity lends itself to the development and implementation of exceed rules and best policies encourageary to the positive outcomes experienced by patients (Kolcaba, 2007).To translate the concepts to practice the dominance of a holistic intervention can be targeted to the taxonom ic structure for enhancing comfort in a specific patient, family, or nurse universe over time. Holistic comfort is defined as the immediate experience of being strengthened through having the needs for relief, ease, and transcendence met in four contexts of experience (physical, psychospiritual, social, and environmental).The comfort theory has been operationalized in many research settings with a variety of patient and target populations ranging from end of life care to the comfort of nurses (xxxx).Resnick Theory of Self-EfficacySelf efficacy is described as a way to organize an individuals judgment of his or her capability to execute a course of action. The Theory of Self-efficacy states that self-efficacy expectations and outcome expectations are not only influenced by behavior, but also verbal encouragement, reflective thinking, physiological sensations and role or self-modeling (Bandura, 1995).. finished self evaluation an individual judges their capability to perform and ce remonious self expectations which is visually depicted in the conceptual model (Appendix 2) (Resnick, 2008).Resnicks Theory of Self Efficacy is based on Banduras social cognitive theory and conceptualizes person-behavior-environment as triadic reciprocality the foundation for reciprocal determinism (Bandura, 1977, 1986). most(prenominal) of the research into self-efficacy beliefs among elder adults has been quantitative and has consistently supported the influence of those beliefs on behavior. However, it has not been open how efficacy beliefs actually influence motivation in older adults, or what sources of efficacy-enhancing education help strengthen those beliefs.Kolcabas Comfort Theory Description, Analysis, and EvaluationTheory DescriptionHistorical context. The Comfort Theory is a humanistic, holistic, patient need based nursing derived middle range theory (Kolbaca, xxxx). The concept of comfort has had a historic and consistent presence in nursing. In the early 1900s , com fort was considered to be a goal for both nursing and medicine, as it was believed that comfort led to recovery (McIlveen Morse, 1995). Over time comfort has become an increasingly minor focus, at times reserved only for those patients for whom no further medical treatment options are available (McIlveen Morse, 1995).The term comfort is used as a noun (comforter), adjective (comforting), verb (to comfort), or adverb (comfort the patient) (xxx). It is also used as a negative (absence of discomfort), neutral (ease), or positive (hope inspiring). Webster (1990) defines comfort as relief from distress to soothe in sorrow or distress a person or thing that comforts a state of ease and quiet enjoyment free from worry anything that makes life easy and the lessening of misery or grief by calming or inspiring with hope. The origin of comfort is confortrare which means to strengthen greatly(Kolcaba, 1992). Based on the diversity of these terms comfort is a complex term. Kolcabas (1991) conc ept analysis of comfort helped to clarify the role of comfort as a holistic concept for nursing. This review confirmed that comfort is a positive concept and is associated with activities that nurture and strengthen patients (David, 2002). Over a period of years and revisions Kolcaba (1994) developed the comfort theory which continues to evolve and change with changes as recent as 2007 (Figure 2).Structural Components.Assumptions. Kolcabas Theory of Comfort (1994) makes four basic assumptions about reality. She assumes that domain beings have holistic responses to complex stimuli comfort is a suited holistic state that is germane to the discipline of nursing human beings actively achieve to meet, or to have met, their basic comfort needs, and that comfort is more than the absence of pain, anxiety, and other physical discomforts (Kolcaba , 2009).Concepts. Kolcaba defines six concepts of comfort which are relative to patients, families, and nurses (Table 1) . The term family, as de fined by Kolcaba (2003) encompasses significant others as obstinate by the patient (Kolcaba, 2003 Kolcaba, Tilton Drouin, 2006). The source concept is of comfort needs which is the relief/ease/transcendence in physical, psychospiritual, sociocultural and environmental contexts of human experience. Comfort interventions in the model are defined as interventions of the health care team specifically targeting comfort of the patient, family and nurses. Intervening variables are positive or negative factors over which the health care team has little control, including physical limitations of the hospital or patients home, cultural influences, socioeconomic factors, prognosis, concurrent medical or psychological conditions. Health-seeking behaviors are those behaviors of patient, family or nurses (conscious or unconscious) which promote well-being may be internal, external or towards promoting a peaceful death. The final concept, institutional integrity, added in most recently, are valu es, financial stability and wholeness of health care facilities at the local state or national levels.Propositions. To help test the concept of nurses comfort caring for dying infants, propositions five and six of Kolcabas comfort theory are examined. These propositions state that patients, nurses, and other members of the healthcare team agree upon desirable and realistic health seeking behaviors (HSBs) (five) and if enhanced comfort is achieved, patients, family members, and/or nurses are strengthened to engage in HSBs, which further enhances comfort (six). These propositions provide rationale for why nurses and other health care professionals should focus on the patient, family, or in this case the nurses comfort beyond unselfish reasons. Because health seeking behaviors include internal and external behaviors almost any health-related outcome important in a healthcare setting can be classified as a health seeking behavior (Peterson Bredow, 2010). The desirable and realistic he alth seeking behavior (HSB) for this study is nurses comfort (knowledge and skills) to relieve moral distress in caring for a dying infant and their family. Several studies support that moral and other types of distress are frequently observed in nurses who care for dying infants (Frommet, 1991) and most significantly indicate that nurses are seeking education regarding patient end of life issues (XXXXX). It is believed that reducing this distress and frustration can be affected through an effective end of life educational programs and is likely to improve the knowledge and skills nurses need to help increase their comfort level in caring for dying infants (xxxxx).Functional Components. Visualizing the concepts in the conceptual model, theTheory Analysis and EvaluationTo analyze and evaluate Kolcabas Comfort Theory (1994) the strong foundation, structural integrity, and operable adequacy of the theory using Smith and Liehrs (2008) Framework for the Evaluation of Middle Range Theo ries is discussed below (Appendix 1).Substantive foundations. Assessing the substantive foundation of a middle range theory is based on four criteria (Smith, 2003). The first cadence evaluates whether the theory is within the focus of the discipline of nursing. Kolcabas comfort theory successfully addresses four concepts comprising the metaparadigm of nursing, defining the concepts as they correspond to the theory (Dowd, 2002 Kolbaca, 2007) as well as presents a diagram of how the Comfort Theory relates theoretically to other nursing concepts (Figure 2) (Kolcaba, 1994) . Nursing is described as the process of assessing the patients comfort needs, evolution and implementing appropriate nursing interventions, and evaluating patient comfort following nursing interventions. psyche is described as the recipient of nursing care the patient may be an individual, family, institution, or community. Environment is considered to be the external surroundings of the patient and can be manipul ated to increase patient comfort. Finally, health is viewed as the best functioning of the patient as they define it. The ability of the framework to aim interventions that help guide nursing interventions to increase comfort supports the discipline of nursing, and in doing so meeting the first criteria.The second criterion evaluates whether the assumptions are specify and congruent with the focus. The four assumptions in the Comfort Theory are explicitly stated and so meet the second criteria. Comfort theory (xxxx) assumes that humans beings have holistic responses to complex stimuli comfort is a desirable holistic state that is germane to the discipline of nursing human beings actively strive to meet, or to have met, their basic comfort needs, and that comfort is more than the absence of pain, anxiety, and other physical discomforts (Kolcaba , 2009).Because the Comfort Theory (XXXX) substantially describes the concept of comfort at the middle range level of discourse, the third criterion of the substantive foundation is met. Kolcabas (1991) concept analysis of comfort helped to clarify the role of comfort as a holistic concept for nursing. This review confirmed that comfort is a positive concept and is associated with activities that nurture and strengthen patients (David, 2002). The Comfort Theory provides an excellent description, explanation, and interpretation of the comfort concept in multiple domains and practice settings. Comfort theory is at the middle range level in that is defined in a measurable way and can be operationalized in both research and practice settings.The final criterion for this fellowship evaluates if the origins are rooted in practice and research experience. The Comfort Theory has been used in numerous practice and research settings to provide a framework where patients have comfort needs and enhancing their comfort is valued. It has also been used to enhance working environments, especially for nurses, and most recently as a framework for working toward national institutional recognitions. More specifically separate are all of the theory have been used to test the intensity of holistic interventions for increasing comfort (xxxxxxx), to demonstrate the correlation between comfort and subsequent HSBs (xxxxx) and to relate HSBs to desirable institutional outcomes. It has also been used as a framework for helping families make difficult decisions about end of life (xxxxx). International and national healthcare institutions have also used Comfort Theory to enhance the work environment for nurses (xxxx). In these cases, nurses comfort is of interest and is theoretically related to the integrity of the institution. Summarize specific studies and tools used here.Structural integrity. There are four criterion for evaluating structural integrity. The first criterion is that the concepts are well defined. The concepts (defined above) of comfort needs, comfort interventions, intervening variables, enhanced comfort , health-seeking behaviors, and institutional integrity are clearly defined and easy to understand. There are numerous examples of applying the concepts in the literature for further clarification (xxxxx).The second criterion of structural integrity is that concepts within the theory are at the middle range level of abstraction. The concepts of the Comfort Theory-comfort needs, comfort interventions, intervening variables, enhanced comfort, health seeking behaviors, and institutional integrity are near the selfsame(prenominal) level on the ladder of abstraction at the middle range level. They are more concrete because they can and have been operationalized and measured (xxxxx).The third criterion of structural integrity is that there are no more concepts than needed to explain the phenomena. Overall, the concepts adequately explain the phenomena of comfort. The theory is synthesized and organized in a simple manner. Lastly, the fourth criterion evaluates whether the concepts and re lationships among the concepts are logically presented with a model. In the Comfort Theory (1994) model the ideas are integrated to create an understanding of the whole phenomenon of comfort in a model. The Comfort Theory (1994) model is a great example of presenting the concepts and statements in a analog logical order so the appreciation of the theory can be recognized (Smith, 2003).Functional adequacy. Because the criterion for functional adequacy overlap more or less the five criterion will be discussed collectively. The five criterion include theory can be applied to a variety of practice environments and clients empirical indicators have been identified published examples exist of research and theory in practice and that the theory has evolved through scholarly inquiry. The Comfort Theory easily meets all of these criterions. For example, the Comfort Theory has been used widely in a variety of research in practice settings and patient and family populations. nonetheless tho ugh the Comfort Theory has been used most widely with patients and families at the end of life and surrounding holistic palliative care nursing interventions, there has been a broad application of the theory in other populations as well including mothers in labor (xxxx), Alzheimer patients (xxxx), pediatric intensive care unit patients and families (xxxx), patients on bedrest (xxxx), those undergoing radiation therapy (xxxx) and for infants comfort and pain (xxxx). Most recently research of using the theory in practice has spread out to support institutional nursing recognition and comfort in the nursing working environment. In each of the populations mentioned above a psychometric comfort instrument has been developed as empirical indicators of concepts in the theory. However, the empirical indicators work beyond empiricism and some include perceptions, self reports, observable behaviors and biological indicators (Ford-Gibloe, Campbell, Berman, 1995 Reed, 1995). The Comfort Theo ry (1994) has also been revised with the latest revision in 2007. The empirical adequacy of the Comfort Theory is evidence of the maturity of this theory (Smith, 2003).SummaryThe Comfort Theory (1994) is a well defined and well tested theory. Its strength lies in the versatility, adaptability, and testability of the concepts. The comfort theory clearly defines the concepts in the theory and the relationship between them. Because the comfort theory meets most of the substantitive foundations, structural integrity, and functional adequacy criteria the Comfort Theory (1994) is a strong middle range theory. An area that could increase the generalizability especially for nursing institutions is a change in the term in the model of nursing interventions to comfort interventions (xxxxx).Resnicks Self-Efficacy Theory Description, Analysis, and EvaluationTheory DescriptionHistorical context. Resnicks Theory of Self Efficacy is based on Banduras social cognitive theory and conceptualizes pers on-behavior-environment as triadic reciprocity the foundation for reciprocal determinism (Bandura, 1977, 1986).The cognitive appraisal of these factors results in a perception of a level of confidence in the individuals ability to perform a certain behavior. The positive performance of this behavior reinforces self-efficacy expectations (Bandura, 1995).Structural Components. Although it is not explicitly stated, the core of this theory assumes that people can consciously change and develop or control their behavior. This is important to the proposition that self-efficacy also can be changed or enhanced through reflective thought, general knowledge, skills to perform a specific behavior, and self influence. This perspective is rooted in the model of triadic reciprocality (foundation for reciprocal determinism) in which personal determinants (self-efficacy), environmental conditions (treatment conditions) and action (practice) are mutually interactive influences. Therefore, improving performance depends on changing some of these influences (Bandura, 1977). In order to determine self-efficacy an individual must have the opportunity for self evaluation to evaluate how likely it is he or she can achieve a given level of performance.Concepts. The two major components of self efficacy include self-efficacy expectations and outcome expectations (Table 2). Self-efficacy expectations are judgments about the personal ability to accomplish a given task. Outcome expectations are judgments about what will run into if a given task is accomplished. These two components are differentiated because individuals can believe a certain behavior will result in a specific outcome, however, they may not believe they are resourceful of performing the behavior required for the outcome to occur (Bandura 1977, 1986). For example, a NICU nurse may believe attending an end of life education series will increase his/her knowledge and skill and ease moral distress, but may not believe that t hey could provide sensitive care for some ethical, religious, or moral reason. It is generally anticipated, but not ever so realistic that self-efficacy will have a positive impact on behavior. There are times when self-efficacy will have no or a negative impact on performance (Vancouver, Thomspon, Williams, 2001). Bandura (1977, 1986, 1997) suggests that outcome expectations are based largely on the individuals self-efficacy expectations, which generally depend on their judgment about how well they can perform the behavior can be disassociated with self-efficacy expectations and are partially separable from self-efficacy judgments when extrinsic outcomes are fixed. Because the outcomes an individual expects are the results of the judgments about what he or she can accomplish, they are unlikely to summate to predictions of behavior (Bandura, 1977).Judgments about ones self-efficacy is based on four cultivational sources including enactive attainment, vicarious experience, verbal persuasion and physiological state. The first source, enactive attainment, or the actual performance of a behavior has been described as the most influential source of self-efficacy information (Bandura, 1986, Bandura Adams, 1977). There has been repeated empirical evidence that actually performing an application strengthens self-efficacy beliefs due to informational sources (Bandura, 1995). The second source, vicarious experience or visualizing other equal people perform a behavior, also influence self-efficacy (Bandura, Adams, Hardy, Howells, 1980). Conditions that impact vicarious experience include amount of exposure or experience to the behavior (least experience causes greater impact) and amount of instruction given (influence of others is greater with indecipherable guidelines) (Resnick Galik, 2006). Another source verbal persuasion or exhortation involves notice an individual he or she has the capabilities to master the given behavior. Verbal encouragement from a tru sted, credible source in counseling or education form has been used alone to strengthen efficacy expectations (Castro, King, Brassington, 2001 Hitunen et al. 2005 Moore et al., 2006 Resnick, Simpson, et al., 2006). The final information source physiological feedback or state during a behavior can be important in relation to coping with stressors, health functioning, and physical accomplishments. Interventions can be used to alter the interpretation of physiological feedback and help individuals cope with physical sensations, enhancing self efficacy and resulting in improved performance (Bandura Adams, 1977).Propositions.

From these journals, it has been concluded an Artificial watchword operation mickle be do to predict the talent of the ken. base on the results, a stiltbird cap tail be created, or eve grouting works toilette be per conventioned to improve the lodge military posture of the structure.The commonest function of arrange is to transfer a load that set up non be adequately throwed at shal impression depths to a depth where adequate support becomes available, also against uplift furys which cause cracks and an opposite(prenominal) damages on superstructure.A pushchair passel is described as a the great unwashed which can pass through weak material, whilst its tip get across a narrow distance, which in turn leads to a layer of im turn out boot substance. When lots atomic number 18 installed onto a layer with minimal ability to support, and the appearance competency is being carried by skirmish which is acting on the sides of the pile, they be called friction set up.Many times, the load-carrying capacity of scads results from a combination of hint denyance and skin friction. The load taken by a hit pile can be determined by a nonoperational load test. The allowable load is obtained by applying a constituent of preventative to the failure load.Types of slewsPiles argon of various types. These set up ar classified based on the scope of formula and flaw type. find out 3. Common Driven Pile TypesConcrete PilesPrecast cover rafts can be either reinforced concrete pile or pre judgeed concrete arrange.Concrete is adaptable for a wide range of pile types. It can be use in precast form in driven loads, or as insertion units in bore piles. Dense well-compacted dear- quality concrete can withstand fairly rugged drive and it is resistant to attack by aggressive substances in the nastiness, or in seawater or state water.However, concrete is precast piles is liable to damage (possibly unseen) in hard impetuous conditions. Weak, honeycombed concrete in cast-in-situ piles is liable to disintegration when aggressive substances atomic number 18 precast in farmings or in maroon water.Cast In family Concrete PilesClosed-ended hollow tubular plane sections of reinforced concrete or steel which be first driven into the globe and then change with in-situ concrete.Cast-in-place concrete piles with their shell driven with mandrel argon typically 50 to 80 ft (15 to 24 m) large and can specifically be casted for a wide range of loads. typical loads that these piles can carry be 50 to cxx kips (222 to 534 kN) provided the maximum stress in concrete, is non more(prenominal) than 33% of 28-day lasting ness. estimate 4.

H-shaped, triangular-shaped, hexagonal-shaped, etc). name 6. Precast Reinforced Concrete PileThe aspect of pre-cast concrete piles are done either in-situ or factory. Production and construction process widely affects the quality of the pile.A pile shoe should be glacial to the pile, in case the flaw deposits contain a lot of boulders. This protects the pile while performing hard driving.For prestressed sections the maximum stresses should not exceed (0.33c 0.27 pe) where pe = aftermathive prestress stress on the section.The main disadvantages of these piles are that they are fractious to handle without damage unless prestressed. They swallow a high initial cost, and prestressed piles are difficult to splice. It is also difficult to manufacture, discipline to longitudinal and transverse cracking, not appropriate for curved or flared structures, compound for skews.The advantages of these pile types include high load capacities, corrosion tube, and resistance to hard driving. Absolute minimum depth of precast bridge for short and mean(a) spans. Expedites stage construction. cut ShaftsDrilled shafts are also known as caissons or piers or bored piles. This is often known to be a cost workive solution which is practiced worldwide. This is a widely apply type of deep-foundation. Drilled Shafts are widely apply in the construction of bridges and large buildings. This technique is employ in construction areas where large loads along with askance resistance are key factors.Figure 7.1. Drilled ShaftThe main advantages are that it is economical, it could minimize pile require for pile cap, meagrely less noise and reduced vibrations, adapts easily to alter site conditions and has high axile and askance loading capacity.The main disadvantages are that it is extremely sensitive to construction procedures, not ideal for contaminated sites, and wishing of qualified inspectors.Figure 7.2. Drilled ShaftA Drilled Pile is made of concrete or grou t and cast or poured, in a plastic state, into a drilled smother in the earth. Augercast, Drilled Shafts, Drilled Cast-in-situ and, their variations are all forms of drilled piles. Completed drilled piles cannot be easily inspected after installation and can be difficult to install in very soft or idle soils, wet, and nautical conditions.A Drilled Pile removes soil from the land and the resulting round hole is filled with concrete or grout.Steel PilesThese are more expensive then timber or concrete however this disadvantage whitethorn be outweighed by the ease of handling of steel piles, by their ability to withstand hard driving, by their resilience and strength in bending, and their capability to carry heavy loads. Steel piles can be driven in very long lengths and cause little ground displacement. They are liable to corrosion above the soil line and in disturbed ground, and they require cathodic protection of a tong feel is in demand(p) in marine structures. Long steel piles of slender section may suffer damage by buckling if they deviate from their true conjunctive during driving.Figure 8. Steel PilesSteel piles are strong, light to handle, and capable ofcarrying heavy loadsto deeper bearing stratum. They can be extended to any length since splicing isrelatively slow, and these can also be readily cut to any required length. This makes steel piles equal for areas where the depth of bearing strata are variable. Various types of steel piles in common use include pipe piles, H-section piles, box section piles, and taper and fluted tubes. Pipe piles and H-section piles are the most commonly employ steel piles in engineering practice. Steel pipe piles can either be driven open ended or closed ended. Open-ended piles will experience less driving resistance and can be drilled through obstructions such as boulders and rudiments.The piles are generally economical in the range of 40 to 80 ft (12 to 24 m) and can carry loads as high as about 250 k ips (1115 kN). Pipe piles are most suited where overburden is soft clays, silts, and unstrain-to-medium dense sand and is nether(a)lain by dense-bearing granular material.H-PilesA form of Steel pile is known as H-Pile. These are wide-flanged sections made of steel. The biggest advantage of this pile is that the displacement of soil becomes very less, when compared against other soil displacement methods practiced in the world. The H-pile falls on a lower floor small displacement category.Figure 9. H-PilesTimber piles cannot be driven through hard ground.Steel H-piles are essentially end-bearing piles. Due to limited delimitation area, H-piles cannot generate much frictional resistance.Corrosion is a study job for steel H-piles. The corrosion is controlled by adding copper into steel.H-piles are easily spliced. They are ideal for highly variable soil conditions.H-piles can bend chthonian very hard ground conditions. This is known as dog legging, and the pile installation super visor needs to make sure that the piles are not out of plumb.H-piles can get plugged during the driving process.If the H-pile is plugged, end bearing may increase due to bigger area. On the other hand, skin frictionmay become smaller due to smaller wall area.When H-piles are driven, both analyses should be done (unpluggedand plugged) and the lower value should be used for design.Unplugged Low end bearing, high skin friction.Plugged Low skin friction, high end bearing.Advantages are that H-pile is available in various lengths and sizes easy to splice high capacity low soil displacement umpteen penetrate larger obstructions with driving shoes.The disadvantages are that it is vulnerable to corrosion, hence not recommended as friction piles in granular soils may force the h-pile to bend on the weaker axis, during the pile-driving process. Due to this, in that location is a high find out of curvature, which may result when the piles are driven into a larger depth.CylindricalCylindrica l piles put on a high axial compressive strength for high bearing capacities they throw off high moments of inertia and accordingly can serve well as both a column and a foundation pile chthonic high vertical and lateral loads.Figure 10. Cylinder PilesCylinder piles are often used in nearshore applications where smaller foundation piles would require caisson construction and other costly measures. Drilled shafts catch similar load bearing properties and capabilities, however, they are generally more costly than piles installed by impact driving.Timber PilesUntreated timber piles may be used for temporary construction, revetments, fenders and similar work and in ageless construction where the cutoff elevation of the pile is below the permanent ground water table and where the piles are not exposed to marine borers. They are also sometimes used for trestle construction, although treated piles are preferred. Timber piles are difficult to extend, hard to anchor into the groundwo rk to resist uplift, and subject to damage if not driven care goody. Timber piles also nurse a maximum allowable bearing capacity of 45 Tons, whereas most structure piles are designed for at least 70 Tons. These piles are mostly installed by driving and are best suited as friction piles in granular material.Figure 11. Timber PilesThe main advantages of timber piles are that they have low initial cost, are easy to handle, and resist vector decomposition when they are permanently submerged.The main disadvantages are that it is tough to splice, are vulnerable to damage in hard driving, and are susceptible to decay unless treated. Treatment becomes necessary when these piles are intermittently submerged.Composite PilesMaterials may be used in combination in piles and the most common example is the use of steel and concrete. This may be by using driven steel casings of various types filled with a structural core of concrete, or a steel pile protected externally by concrete casing the latter is normally only possible for exposed lengths of piles such as would be encountered in a jetty structure. There are, however, forms of steel pile, which have grout pipes passim their length, which are used for forming a protective outer casing after driving.Figure 12. Composite PilesThe maximum stresses in timber, steel and concrete should not exceed the values specified above for various materials.The main disadvantage of these piles is that it is difficult to attain good joint amongst two materials.The main advantage is that considerable length can be provided at comparatively low cost. High capacity may be possible depending on materials.use of piles in constructionThere are two types of piles used for constructionDisplacement PilesNon-Displacement PilesDisplacemeNt PileThe type of pile, which is rammed into the ground, which does not remove the soil, simply displaces the soil downwards and sidewise. This type of pile foundation is called displacement pile.Figure 13. Di splacement PilesThis method piles displace soil during their installation, such as driving, jacking, or vibration, into the ground. Examples of these types of piles are timber, precast concrete, prestressed concrete, close-ended steel pipe, and fluted and tapered steel tube piles.The advantages of displacement piles areMaterial forming pile can be inspected for quality.Soundness originally driving.Not liable to squeeze or necking.Construction operation not affected by ground water.Projection above ground level advantageous to marine structures. piece of tail be driven in the very long lengths.The disadvantages of displacement piles areMay break during driving, necessitation replacement pile.Unseen damages may occurring thus decreasing the carrying capacity.Noise pollution may be caused during hammering. vibe caused during the hammering process may pose a threat to nigh structures.Non-DisplacemeNt PileThese Piles do not displace soil during their installation. These piles are form ed by first removing the soil by thudding and then placing prefabricated or cast-in-place pile into the hole from which an equal volume of soil was removed. Their placement causes little or no change in lateral ground stress, and, consequently, such piles come up less shaft friction than displacement piles of the analogous size and shape. Piling operation is done by such methods, as augering (drilling, rotary boring) or by grabbing (percussion boring). Most common types of no displacement piles are bored and cast-in-place concrete piles.The advantages of non displacement piles areMaterial forming pile is not governed by handling or driving stresses.Can be installed in very long lengths.No ground heaves.Can be installed in conditions of low headroom.Figure 14. Non Displacement PilesThe disadvantages of non displacement piles areConcreting in water-bearing soils require special techniques.Inspection of concrete cannot be done after installation.Cannot be extended above ground level without special adoption. publications REVIEWDescription of JournalsThis section contains the description paragraph for the 5 technological journals which has been chosen to support the main topic of research.Adel M. Hanna, George Morcous, and bloody shame Helmy (2004) Efficiency of Pile Groups Installed in Cohensionless Soil Using Artificial Neural Networks.Adel M.Hanna, George Morcous and Mary Helmy evaluated the efficiency of pile groups installed in cohension-less soil subjected to axial loading. The authors feel that a resistance to the column load may result in a study difference between the total capacity of the private piles and the group piles. This could lead to end of the building. The authors have developed an ANN (Artificial Neural Network) mannikin to process the research. They have found that the ANN model is nearly 80% accurate to the predicted value. The predictions are very accurate, even with low tolerance values. They have also made an ANN model which can b e easily updated when new data are obtained from laboratory and field tests.Kevin J.Bentley and M.Hesham El Naggar (2000). Numerical Analysis of Kinematic Response of unmarried PilesKevin and Hesham have done a research on unity piles, after anticipating the ruinous losses in basis of human life and economic assets due to the earthquakes. They wanted to develop a model which evaluates the do of ground motion on piles. Their aim was to develop a finite subdivision model that can accurately model the kinematic soil-structure interaction of piles, account for non elongate behavior of soil, discontinuity at the pile soil interface, energy looseness and flap propagation. They found that the tack of the response of piles in pliant soil was slightly amplified in terms of accelerations and Fourier amplitudes.The authors have taken a good amount of information from previous(prenominal) researches made. They have found that the previous studies had its own drawbacks, which were co ncluded that interaction make on kinematic loading are not large at low frequencies but are significant for pile head loading. The authors used finite element program, ANSYS to analyze the full 3D transient method. They have found that the deflections obtained in the study were slightly niftyer than those from other tests. The authors concluded that the matter of soil layer overlaying the bedrock was to dramatize the bedrock motion, which results in a higher(prenominal) free-field motion for the soil parameters used in the compend. Increased Fourier amplitudes at the plethoric frequency was an deed of soil plasticity. It slightly decreased the maximum acceleration amplitudes.Jinoh Won and Fred H. Kulhawy (2009) decline of Pile Head Displacement for Restrained Head Single Pile.The authors conducted a study on the effect of pile head mending on the displacement of laterally loaded pile groups using analytic methods. It was found that the soil parameters have a major do wo rk on the decline factor, while the pile property influence is relatively minor. The principle behindhand the problem is described as most pile foundations have pile cap that reduces the lateral displacement because of restraining effect on the pile heads. The authors well-read that the previous researches which were done were for small-scale tests only. The authors have performed numerous tests, from which they found that there is a variation of reduction factor with soil properties for the drain cohensionless model. The authors have done a quantitative analysis to investigate the effect of pile head restraint on the displacement using an analytical method. Their design chart is matched reasonably well with the data-based and numerical data.Ling-gang Kong and Li-min Zhang (2007). Effect of Pile-cap tie-in on Behaviour of Torsionally Loaded Pile GroupsEvaluation of the responses, under torsion, of fixed as well as pinned pile cap was done by the authors. They have researched t hat, the torsional capacity of the pile group is significantly influenced by the pile-cap. The same applies with the pile-groups contortion assignment. The authors hire that grouped piles are usually used as foundations for inshore platform, bridge bents and tall buildings. Due to natural disturbances like meander and brandish actions, ship impacts or high-speed vehicles, the grouped piles may be exposed to significant torsional loads, leading to destruction and catastrophic effects on them. The authors have found that the lateral ad torsional resistance of the individual piles is mobilized by a pile group which is subjected to torsion. This could pinch up to 50% of the applied force, whilst the pile-cap foundation is fixed. From the research it has been noted that under loose sand the pile bend a minimal degree. Whereas under dense sand, and the same load, the pile bend less than the loose sand. They have modeled nonlinear soil response and major pile-soil-pile interactions a nd coupling effect in a pile group.Weiming Gong, Guoliang Dai and Haowen Zhang (2009) Experimental Study on pile-end post-grouting piles for super-large bridge pile foundations.The authors made an experimental study on pile-end and post-grouting piles for very large bridge-pile foundations. Before the after-grouting works were evaluated, the authors wanted to analyze the bearing capacity, bearing characteristics and displacement. The authors introduced 21 test piles to perform the experiment. The technique was apply to increase the capacity as well as decrease settlement. The author has done a lot of background researches, across various bridges. From the research it has been found that the capacities are greatly enhanced after pile-base grouting. The Q-s curve before grouting decrease acutely under small loads and have great deviations from existed geological values, which attributes to long term interval between drilling and grouting. So the authors have proved that, by grouting , they have steadily increase the bearing capacity of a bridge.Order of ParagraphsKevin and Hesham have done a research on single piles, after anticipating the catastrophic losses in terms of human life and economic assets due to the earthquakes. They wanted to develop a model which evaluates the effects of ground motion on piles. Their aim was to develop a finite element model that can accurately model the kinematic soil-structure interaction of piles, accounting for non linear behavior of soil, discontinuity at the pile soil interface, energy dissipation and wave propagation. They found that the effect of the response of piles in elastic soil was slightly amplified in terms of accelerations and Fourier amplitudes.The authors have taken a good amount of information from previous researches made. They have found that the previous studies had its own drawbacks, which were concluded that interaction effects on kinematic loading are not significant at low frequencies but are significan t for pile head loading. The authors used finite element program, ANSYS to analyze the full 3D transient method. They have found that the deflections obtained in the study were slightly greater than those from other tests. The authors concluded that the effect of soil layer overlaying the bedrock was to amplify the bedrock motion, which results in a higher free-field motion for the soil parameters used in the analysis. Increased Fourier amplitudes at the predominant frequency was an effect of soil plasticity. It slightly decreased the maximum acceleration amplitudes.The authors conducted a study on the effect of pile head fixity on the displacement of laterally loaded pile groups using analytical methods. It was found that the soil parameters have a major influence on the reduction factor, while the pile property influence is relatively minor. The rationale behind the problem is described as most pile foundations have pile cap that reduces the lateral displacement because of restrai ning effect on the pile heads.

The authors have done a quantitative analysis to investigate the effect of pile head restraint on the displacement using an analytical method. Their design chart is matched reasonably well with the experimental and numerical data.The authors cautiously study the reaction of two types of pile cap (fixed pinned) under torsion. They have researched that, the torsional capacity of the pile group is significantly influenced by the pile-cap. The same applies with the pile-groups torque assignment. The authors claim that grouped piles are usually used as foundations for offshore platform, bridge bents and tall buildings. Due to natural disturbances like wind and wave actions, ship impacts or hig h-speed vehicles, the grouped piles may be exposed to significant torsional loads, leading to destruction and catastrophic effects on them. The authors have found that the lateral ad torsional resistance of the individual piles is mobilized by a pile group which is subjected to torsion. This could thrust up to 50% of the applied force, whilst the pile-cap foundation is fixed. From the research it has been noted that under loose sand the pile bend a minimal degree.

So the authors have proved that, by grouting, they have steadily increase the bearing capacity of a bridge.Addition of Introductory and Concluding SentencesPile is commonly described as a columnar element of a building foundation. Its function is to transfer the load from a superstructure to the hard layer in the soil, or on to the rocks. Kevin and Hesham have done a research on single piles, after anticipating the catastrophic losses in terms of human life and economic assets due to the earthquakes. They wanted to develop a model which evaluates the effects of ground motion on piles. Their aim was to develop a finite element model that can accurately model the kinematic soil-structure interaction of piles, accounting for non linear behavior of soil, discontinuity at the pile soil interface, energy dissipation and w ave propagation.

Increased Fourier amplitudes at the predominant frequency was an effect of soil plasticity. It slightly decreased the maximum acceleration amplit udes.The type of soil is an all important(predicate) entity while fixing piles. The authors conducted a study on the effect of pile head fixity on the displacement of laterally loaded pile groups using analytical methods. It was found that the soil parameters have a major influence on the reduction factor, while the pile property influence is relatively minor. The rationale behind the problem is described as most pile foundations have pile cap that reduces the lateral displacement because of restraining effect on the pile heads.

The authors have done a quantitative analysis to investigate the effect of pile head restraint on the displacement using an analytical method. Their design chart is matched reasonably well with t he experimental and numerical data. The frictional resistance of the pile is directly proportional to the soil cohesiveness, which means if the soil is cohesive, it will have a better make with the area of the side pile.The pile cap distributes the load from the pillars, or piers, to the piles. The authors studied the reaction of the two pile caps (fixed and pinned) cap under torsion. They have researched that, the torsional capacity of the pile group is significantly influenced by the pile-cap. The same applies with the pile-groups torque assignment. The authors claim that grouped piles are usually used as foundations for offshore platform, bridge bents and tall buildings. Due to natural disturbances like wind and wave actions, ship impacts or high-speed vehicles, the grouped piles may be exposed to significant torsional loads, leading to destruction and catastrophic effects on them. The authors have found that a pile group subjected to torsion at the same time mobilizes lateral and torsional resistance of the individual piles and the torsional resistance could thrust up to 50% of the applied force, whilst the pile-cap foundation is fixed. From the research it has been noted that under loose sand the pile bend a minimal degree. Where as under dense sand, and the same load, the pile bend less than the loose sand. They have modeled nonlinear soil response and major pile-soil-pile interactions and coupling effect in a pile group.An Artificial Intelligence based application need to be created which would perform tests based on experimental values.

The authors feel that a resistance to the column load may result in a major difference between the total capacity of the individual

Biomechanical Differences: Male and Female Marathon Runner

Biomechanical Differences Male and Fe potent heroism contest RunnerMore than by brain size or tool-making ability, the homosexual persist species was set a fibre from its ancestors by the ability to jog mile afterward lung-stabbing mile with greater heroism than any other primate.The introductory consultation (Hotz, cc4) simply, yet vividly, expresses the bequeaths of a recent study completed by deuce Ameri quarter scientists, Dennis Bramble and Daniel Lieberman, and released in the journal Nature(2004). Bramble and Lieberman contend that the ability to run grand distances was the driving force shaping the modern serviceman class.Hotzs handstal picture of early mankind as endurance contest manpower and wo custody from the tips of their distinctively all of a sudden toes and grand Achilles tendons to the tops of their biomechanically balanced base on ballss (emphasis added) sets the backdrop for this essayan exploration of the biomechanical varietys betwixt mal e and young-bearing(prenominal) battle of Marathon runners.After a few additive historical com handsts, this essay opens with a presentation of anatomical differences between hands and wowork force with specific reference to caterpillar track then continues with definitions and descriptions of the boundary marathon, as a spurt of organized racecourse sport, and definitions for the term bio chemical mechanism in preparation for a discussion of how the field of biomechanics is utilize to course. With this teaching as a foundation, the target and scope give be articulated followed by presentation of previous methods and findings revealed from a search of the literature on the base of biomechanical differences between male and female marathon runners and c dawdlely-related topics. These findings provide be discussed and conclusions drawn. Finally, recommendations for further look will be presented.To re plait briefly to the enquiry findings of Bramble, a paleontologist a nd biomechanics expert, and Lieberman, a physical anthropologist, to continue setting the backdrop for the essay, Bramble sound outs Running made us human, at least in an anatomical sense. We think cartroad is iodine of the most transforming correct upts in human history (Chui, 2004). courage ravel is an natural action that is reserved for gentleman in the primate world and not customary in other mammals with the exception of dogs, horses and a few others. Bramble and Lieberman contend that footrace permitted humans to scavenge and hunt for food over significant distances and that the high gear protein food they secured was instrumental in developing larger brains (Wilford, 2004).To facilitate raceway, humans developed several traits including large buttocks with strong skunkivenesss which connect the femur to the trunk of the corpse preventing the body from over-balancing with each step. In addition, humans clear a aloofnessy arm-swinging stride and long ligame nts and tendonsincluding the Achilles tendonwhich serve as springs that inventory and release mechanical energy during running.(Hotz, 2004).Brambles reference to todays running in the evolutionary context he and Lieberman conventional provides an assume introduction to the exploration of the biomechanical differences between male and female marathon runners (Wilford, 2004) Today, endurance running is primarily a form of exercise and recreation, but its root whitethorn be as ancient as the farm animal of the human genus.The description of anatomical differences between men and women,which is focused on anatomical stimulates that be mingled in running,begins with a gender-neutral discussion to establish a foundation for the more than than gender-specific information.Rossi (2003) emphasizes the complexity of walking, a precursor torunning. He writes that half(prenominal) of the 650 muscles and tendons in thehuman body be involved in what most lot consider to be the simpleac t of walking. He suggests that, in the evolution of the human body,there were hundreds of adaptations that had to buzz off place,adaptations that unavoidable repositioning of everything in the bodyover several million age. Rossi writesThe arms, no eight-day needed for branch swinging, became shorter, thelegs longer, the pelvis wider, the shoulders narrower, the neck longerand more slender, the spine changed from C-shape to S-shape. Majorchanges were necessary in the hip, knee and ankle pegs. Hundreds ofmuscles, tendons, ligaments and joints gradually shifted in position,size and function. And of course, the spic-and-span stupefy and gait requiredimportant changes in the size and position of all the organs of thechest and abdomen.Rossi suggests that many of these changes were extremely significantfrom a biomechanical perspective. For instance, he calls attention tothe blood pumping requirement of the trusdeucerthy human form Daily in eachindividual, approximately 74,000 qua rts of blood mustiness travel through100,000 miles of blood vessels from the brain to the feet and legs in acircular pattern. Rossi emphasizes the human engineering challengethat was required to design a system that would counteract the effectsof gravity in go blood vertically in this manner. Rossis comments atomic number 18 weakenicularly important in the context of the current discoursebecause they provide some insight into the current state of relevantanatomical features of todays runners and how those features werederived.The anatomy of humans, unlike that of other living creatures,provides for speed and endurance. The unique characteristics related torunning imply (Science in Africa, 2005, citing University of Utah Public Relations, 2004) Skull features. These features, which include sweating from the scalp and face, cool the blood. A balanced head. This shape of head with a relatively flat face,small teeth, and short snout moves the center of the potful backwardwhich stand bys to counter the effects of moving upward and downward duringrunning. A ligament running from the rear of the skill and neck downward tothe thoracic vertebrae. This feature serves as a coldcock absorber thataids the arms and shoulders in counterbalancing the head during runningactivity. Shoulders decoupled from the head and neck. This feature allowsrotation of the body while the head faces forward during running. A tall body. This feature, which includes a narrow trunk, waistand pelvis, provides for increased skin surface allowing for enhancedbody cooling and permits the upper and cut body segments to moveindependently. Short forearms. This feature permits the upper body to act as acounterbalance to the lower body during running activity while reducingthe muscle effect required for maintaining flexed arms. Large vertebrae and disks. This feature permits the human back to accepted heavier laden when runners repair the domain. Large, strong connection between the p elvis and the spine. Thisfeature remain firms more perceptual constancy and shock absorbing capability duringrunning activity. Large buttocks. This feature, and the muscles that form it,stabilize the body during running activity. The connection of thesemuscles to the femur prevents the body from pitching forward. Long legs. This feature allows humans to take large strides duringrunning activity. The tendons and ligaments permit the legs to belighter and less muscular thereby requiring a dinky amount of energyto propel them while running. Large hip, knee, and ankle joint surface argonas. These featuresprovide enhanced shock absorption by reducing the impact in any onespecific argona. Arrangement of oss in the theme. This feature provides for a morerigid foot by creating a stable arch, allowing runners to push off in amore efficient manner and to use ligaments located on the bottom of thefeet as springs. Large heel swot up, short toes, and a big toe. These features provid efor enhanced shock absorption and increased aptitude to push off duringrunning activity.With the running-related anatomical features applicable to allhumans as a foundation, the focus now turns to the differences inanatomical features between men and women, specifically those featuresthat are involved in running activity. Holschen (2004) writes that,until puberty, males and females are equal in terms of strength,aerobic power, soreness size, and weight they also befuddle similar amountsof body plentiful.Starting at puberty, according to Holschen (2004), male and female sexhormones begin bear on bone and lean body mass, circulation, andmetabolism in diametrical ways. A female typically has a wider pelvis,femoral anteversion (inward twisting of the femur), genu valgum (kneestouch but ankles are separated), and immaterial tibial torsion (feet donot line up in a sequential manner because of out-toeing from outwardrotation of the large calf bone). Center of gravity differences betweenmen and women are minimal, correlating more by body image and heightthan with gender. (Atwater, 1985, cited in Holschen, 2004). Whencompared with males, females typically adjudge smaller bones accompaniedby smaller articular surfaces. They also have proportionately shorterlegs with resulting decrease potential force in certain maneuvers.(Holschen, 2004).At puberty, girls gain some(prenominal) fat and lean muscle mass due to theinfluence of female hormones boys lose body fat and add muscle massdue to the influence of male hormones (Holschen, 2004). Women inadulthood have about ten part more body fat than do their malecounterparts (Greydanus, D. and Patel, D., 2002, cited in Holschen,2004). The basal metabolic rate is approximately ten percent lower inwomen than in men. The presence of female hormones mandates that womenrely more on fat metabolism at any given exercise level when comparedto men. In addition, glycogen uptake, storage, and use are increased.(Holschen, 2004, citing Bonekat, H. W. et al., 1987 Dombovy, M. L. etal., 1987 Frankovich, R. J. and Lebrun, C. M., 2000 Nicklas, B. J. etal., 1989 Tarnopolsky, L. J., 1990) Cureton and associates (1988,cited in Holschen, 2004) attribute the differences in muscle strengthbetween men and woman to boney and cardiac muscular hypertrophy andmuscle mass component part they contend that muscle mass in men is for qualityrcent compared to cardinal percent in women.Changes in body composition and circulatory capacity beginning atpuberty result in approximately twenty percent higher(prenominal)(prenominal)cardio-respiratory capacity in men. Men also have comparatively highertype O-carrying capacity, larger heart and lung mass, a higher strokevolume, and higher maximal cardiac output which result in greatereffectiveness in aerobic and anaerobic activities, although dressingcan overcome the inherent differences (Williford, H. N. et al., 1993,cited in Holschen, 2004).The results of the current research foc us to fundamental anatomicaldifferences between men and woman, differences that more often than not begin toappear during puberty and which have some bearing on runningcapability.The term running can be defined as moving swiftly on foot sothat both feet leave the ground during each stride (American HeritageDictionary of the position Language, 2000). The research by Bramble andLieberman (2004, cited in Nature, 2004), which was presented earlier,seems to indicate that running has been part of human existence sinceits beginnings and, in fact, contributed significantly to developmentof human lifespantime today. Humans no longer require running for survival, atleast in their normal affairs that is, typically, humans do not haveto run from danger or run in pursuit of animals to kill for food. Inmodern times, running has taken on a new formcompetition foot racing.This competition racing can be against oneself to achieve ones ownpersonal best or with others. Racing against others can ta ke manyforms ranging from informal competitions between two young friendsracing against one other on a playground to very formal competitionssuch as those in the quadrennial Olympics. The more formal runningcompetitions are typically classified by the length of the run 100,200, 400, 800, 1500, 5000, and 10000 meters as well as marathons(Dollman, 2003).There are many terms that refer to specific forms of foot racing run,dash, sprint, relay, meet, matched trial of speed, footrace, andmarathon (Websters revolutionary World Thesaurus, 1997). Of these, the termsdash and sprint are typically used interchangeably to describe ashort, fast run or race (Websters New World Dictionary, 1988) or ashort, swift exertion (Websters New World Thesaurus, 1997). Organizeddashes and sprints are popularly of 50 meters, 100 meters, 200 meters,50 yards, 100 yards, and 200 yards in length (Websters New WorldThesaurus, 1997). Marathons are a form of long-distance running, whichare on- and off-the-track competitions of more than 3000 meters (Hlus,1997). Specifically, a marathon is a footrace of 42 kilometers, 195meters (26 miles, 385 yards) run over an open course, or anylong-distance or endurance contest People who compete in marathons arecalled marathoners (Websters New World Dictionary, 1998).Physiologically, there is a fundamental difference between a sprint ordash and a marathon. According to Pritchard (1994), A sprinter canexert maximum force throughout the run, but this is not possible forlonger runs, where propelling force must be reduced to match energyavailability.Historically, marathons are not new events. According to legend, thename marathon is derived from the classic city, Marathon, to commemoratePheidippidess run from that city to Athens to announce Greek victoryover the Persians. The marathon was introduced to the Olympics in 1896and todays official distance was established in 1908. (Hlus, 1997 TheColumbia Encyclopedia, 2005) Today, in addition to marathon races in the Olympics, many cities throughout the world serve as sites forannual or other periodic marathons (The Columbia Encyclopedia, 2005).A new form of marathon race has recently taken formthe ultramarathon,which is any organized footrace extending beyond the standard marathonrunning distance of 42 kilometers, 195 metersthey typically begin at 50 kilometers and extend to enormous distances (Blaikie, n. d.).Standard distances for ultramarathons are 50 and 100 kilometers and 50and 100 miles (Meyers, 2002) with the longest certified race being theSri Chinmoy, a 2092 kilometer race held annually in New York (Blaikie,n. d.).The research produced numerous and varied definitions for the termbiomechanics. The following are representative of the findings The study of the mechanics of a living body, especially of theforces exerted by muscles and gravity on the skeletal structure. (TheAmerican Heritage Dictionary of the English Language, 2000). The commitance of mechanical engineering princi ples andtechniques in the field of medicine and surgery, studying naturalstructures to improve those produced by humans (The HutchinsonEncyclopedia, 2003). A experience examining the forces acting upon and within a biologicalstructure, and the effects produced by those forces (The University ofCalgary, n. d.). The science that deals with forces and their effects, applied to biological systems (Freivalds, 2004). The application of the principles and techniques of mechanics to the human body in act (Snowden, 2001). Biomechanics is a specific field which evaluates the motion of aliving organismand the actions of forces on that organismacombination of several different areas of study including anatomy andphysiology, kinematics (the study of motion without respectfulness to itscauses), kinesiology (the study of human movement) and kinetics (thestudy of forces acting on a system) (National Endurance SportsTrainers Association, 2005).In furnishing a definition for biomechanics, the Quintic ConsultancyLtd. (2005) provides some additional insight into the origin anddetails of the term, stating that the name is derived from the Greekbios meaning life and mekhaniki meaning mechanics, adding that theseindividual terms are unite to mean the mechanics of life forms.The biomechanics discipline includes research into various life formsincluding plants, insects, reptiles, birds, fish, humans, and others.Within the human specialty, topics include mechanics of bone, tooth,muscle, tendon, ligament, cartilage, skin, prostheses, blood flow, airflow, eye movement, joint movement and whole body movement (TheQuintic Consultancy Ltd., 2005).Historically, according to Knudson (2003), the study of humanbiomechanics has alternated between accentuate each of its twocomponentsthe biological and the mechanical. Atwater (1980, cited inKnudson, 2003) claims that, during the first half of the twentiethcentury, scholars emphasized medicine and anatomy under the termkinesiology. The dist inct field of biomechanics was born from the workof biomechanists in the 1960s and 1970s. From that point the fieldbegan to emphasize mechanics over biology. Today, the competing forcesto move the discipline either toward a biological emphasis or toward amechanical emphasis continue (Knudson, 2003).The field of biomechanics, already narrowed in a previous elementfrom consideration of all life forms to only humans for the purpose ofthis essay, can be focused even further to a sub-field called sportsbiomechanics (The Quintic Consultancy Ltd., 2005)Sports biomechanics uses the scientific methods of mechanics tostudy the effects of various forces on the sports performer. It isconcerned, in particular, with the forces that act on the humanneuromusculoskeletal system, velocities, accelerations, torque,momentum, and inertia. It also considers aspects of the behavior ofsports implements, footwear and surfaces where these ask athletic proceeding or blot prevention. Sports biomechanics can be divided upinto two sections performance onward motion and injury prevention.The Australian Sports Commission (n. d.) furnishes additionaldescriptive information on the application of biomechanics to sports,using a term the Commission calls applied sports biomechanics whichincorporates techniques from physics, human anatomy, mathematics,computing and engineering to disassemble technique to prevent injury andimprove performance. The Commissions division of sports biomechanicsinto two categoriesperformance improvement and injurypreventionechoes the classifications offered by The QuinticConsultancy Ltd.Williams (2003) describes how biomechanics can help runnerperformance, specifically that of the marathoner. stellar(a) into hisrecommendations, he describes how marathon runners use a simplebiomechanical dodging known as drafting off another runner whenrunning into the wind to reduce the unbecoming effects of air resistanceand reduce type O consumption for the latter part of the race. HewritesThe goal of the sport biomechanist is to improve movement cleverness,mainly by maximizing propulsive forces and minimizing resistive forces,and thus provide the supporter with a mechanical edge. employ high-speedcinematography, the biomechanist can analyze a runners form and detectproblems in running form that may be inefficient, such as overstriding,and that may waste energy. Although most elite and experiencedmarathoners have developed efficient running styles, even a smallimprovement in running efficiency may sour a significant differenceover the duration of a marathon.In addition to the strategy of drafting off another runner,Williams offers several other biomechanical strategies includingselecting the proper activewear (i.e. uniform and shoes) and optimizingbody weight and composition.Thus far the topics of anatomical differences between men and womenwith specific reference to running definitions and descriptions of theterms marathon (as an organized, compe titive form of running) andbiomechanics and the application of biomechanics to running have beenpresented and discussed. With this as a foundation, the focus of thediscourse now turns to the topic of biomechanical differences betweenmale and female marathon runners and closely-related topics.The objective of this portion of the essay will be to explore thebiomechanical differences between male and female marathon runnersthrough a round and analysis of selected literature on the topic andrelated issues.The scope of the literature canvass will include marathon running withspecific reference to available information on the differences betweenmales and females. Although running of shorter distances (e.g. sprintsand dashes) and longer distances (e.g. ultramarathons) as well as othersports activities are excluded from the specific scope of this essay,references will be made to these activities when they related tomarathon running. execution of instrument improvement and injury preventi on werementioned as the two primary areas communicate by applied sportsbiomechanics. Gender-specific issues in each of these areas will beexplored briefly as well. REVIEW OF EXISTING RESEARCH ON METHODS AND FINDINGSOne researcher who has analyze gender differences in enduranceperformance, including marathon running, is Stephen Seiler (1996) ofThe Institute for Sport, Agder College in Kristianstad, Norway. Hewrites Some years ago it was proposed by some that women wouldactually perform better than men at ultra-endurance type activities.This theory has been disproved in the laboratory and in practice. Aslong as women are women, I dont think they will surpass men, statesNorways perennial marathon winner Grete Waitz (quoted in Holden,2004). The anatomical differences between females and their malecounterparts, specifically those that affect running, were presented inthe introduction. flat an attempt will be made to show that the generalanatomical differences between men and women exte nd to biomechanicaldifferences that affect marathon running performance and injury.Holschen (2004) writes that The female athlete remains less wellunderstood and less well canvass compared with male athletes,especially in the areas of performance factors, repetitive stress, andacute injuries. She continues Logical reasons for this include (a)a limited two-generation span of the high-profile elite female (b)fewer females involved in coaching, research, and sports medicine and(c) limited areas of female offspring sports historically (gymnastics,swimming, dance). The reality of Holschens findings proved to be truein the current research activity. There were remarkably few availablesources on the biomechanics involved in womens marathon running. Mostof the research either applied to males or did not determine the gender.Results from a review of selected research literature will be presentedin this section beginning with gender-differentiated research resultson running performance. Fo llowing this, results of research into thetwo applied sports biomechanics specialties will be presented with afocus on studies concerning footwear and injuries.Holden (2004) writes about performance in running with specialattention to female runners. She quotes physiologist Henrik Larsen ofthe Copenhagen Muscle Research Centre in explaining womens marathonperformance vis--vis men Women had not developed long distancethats why the improvement is much greater on the marathon. Larsen,who seems to attribute the performance improvements of femalemarathoners to focused training instead of anatomic factors, claimsthat we dont see any higher oxidative capacity in women. Holdenalso offers comments by exercise physiologist Timothy Noakes of theUniversity of mantel Town, South Africa who agrees with Larsensassessment A smaller body frame gives women an edge on endurancebutmen can run 10% faster even when the difference in body size iscontrolled for.Stephen Seiler (1996), who was quoted at the start of this sectionstating that the proposal that women could perform better inultra-endurance activities has been disproved, confirms that there aresome physiological differences between the sexes that impactperformance in females independent of age. He notes that there is aten percent difference in marathon times between men and women, addingthat this difference is the uniform across the distance runningperformance spectrum. He attributes this difference, not to adifference in training, but to physiological differences. He studiedmaximal oxygen consumption, the lactate threshold, and efficiency toanalyze the differences between men and women as these factors mightaffect long-distance running performance maximum Oxygen Consumption. There is a 43 percent differencebetween men and women with men possessing a VO2 max (oxygen-deliveringcapacity measure) of 3.5 liters per minute and women with a capacity of2.0 liters per minute. Seiler attributes this in part to male size menare la rger. But, even when size is factored in, male oxygen consumptioncapacity is ease fifteen to twenty percent higher. Males have agreater capacity to deliver oxygen to their muscles and organs. The Lactate Threshold. This is the point at which lactic acidbegins to accumulate at higher than normal levels in the blood streamindicating an exercise intensity boundary at which the level ofintensity can be maintained over a long period and that which willresult in quick fatigue. Seiler does not believe that lactatethresholds are different for men and women as a percentage of their VO2max. Efficiency. After finding conflicting information comparing theefficiency of males and femalesrevealing that females are lessefficient, more efficient, or the same as males in terms ofefficiencySeiler believes that differences in efficiency do notaccount for the differences in endurance performance.Seiler concludes with his determination that the ten percentperformance difference between men and women in endurance running canbe attributed to the first of the three physiological factors hestudiedmaximal oxygen consumption.Another researcher who explored gender differences in athletics,and especially in endurance events, is Dollman (2003). Citing Shepard(2000), Dollman writes that there is consistent evidence, based onobservations, that males possess larger measures of the following(quoted) Heart volume, even when corrected for stature. Haematocrit, which gives males a 13 percent greater oxygen-carrying capacity than females. plasm volume. Total muscle mass, which means that females perform the sameabsolute task at a higher percentage of maximum voluntary contraction,with concomitant vascular ohmic resistance limiting cardiac ejection and peakcardiac output.In addition, male skeletal muscles may have a higher succinatedehydrogenase (an integral membrane protein) concentration (Dollman,2003, citing Costill, et al., 1987). Males may produce bettermechanical efficiency during run ning (Dollman, 2003, citing Miura,1997) although this is arguable as it may be rooted in cultural origins(Dollman, 2003, citing Shepard, 2000).Now attention will turn briefly to a review of selected researchinto the two primary application areas intercommunicate by applied sportsbiomechanics running performance and injuries. Regarding performance,footwear will be discussed followed by a presentation of selectedfindings on research into injuries. Gender issues will be introduced.Lipsky (2001, citing Hennig, 2001) presented research findings ongender-specific requirements for athletic footwear designed forrunning. The research experiment involved fifteen women and seventeenmen of the same body weights, heights, and ages. Each subject wore thesame shoe size and each tested five types of shoes which included threestyles of mens shoes and two styles for women. Using Kistler forceplatforms at a set velocity, ground force reactions, tibialacceleration, angular foot motion, and plantar co mpresss at eightstrategic locations on the foot were measured. According to Lipsky, theexperiment revealed that none of the variables demonstrated asignificant interaction among gender and footwear type meaning, Lipskycontends, that women had the same biomechanical dilemmas in mensshoes as they did in their own footwear. scorn similarity in thetest subjects weight and other factors, men exhibited higher pressurerates in all regions of the foot. Men had significantly higher heelloads, but less midfoot loads, indicating that the arches of women donot support the middle of their feet. According to Lipsky, theseresults support the conclusions that women have a stronger collapse ofthe longitudinal archduring weight bearing and have an increasedtendency of pronation and the smaller amount of pressure to theground. The recommendation from this study is that women should selectrunning shoes that protect against overpronation. This, according toLipsky, will help prevent knee injuries.Bartol d (2004) adds to the literature on the differences inrequirements for athletic shoes for men and women. He claims thatrunning footwear is largely designed and manufactured for malerunners, making little recognition that women have significant injuryissues compared to men. Although Bartold acknowledges that reasons forinjuries are not scientifically established, he indicates thatproposals have been made that known differences in structure maypredispose female athletes to differences in running mechanics, andthese differences may lead to specific injuries, continuing by statingthat anecdotally, we have excellent evidence that the particularbiomechanics of female athletes and the way they run predisposes themto specific injury patterns.With regard to injuries, Parfit (1994) compared running injuries ofmiddle distance runners and marathon runners, concluding that thelatter incur more injuries when compared to the former (approximatelyeighty-two percent for middle distance runners compar ed to ninety-sevenpercent for marathoners). Acknowledging validity questions due to smallrunner populations studied and lack of injury definitions, Parfit foundthat whilst marathon runners suffered from back problems and hipailments, middle distance runners were more susceptible to kneeproblems, stress fractures, and shin splints.Certain types of knee, shoulder and back injuries are more commonin females and can in part be attributed to differences in body shapeand biomechanics, reports Glasgow, Scotlands Daily Record (2004).Taunton et al. (2002) found that there were significant differencesbetween running injuries incurred by men and women. According to thisstudy, knee injuries seemed to be the most common injury in both sexeswith men experiencing higher incidences of the following injuries (thefirst percentage shown in parenthesis is for men the second forwomen) plantar fasciitis, an injury to the fascia connective tissue on the bottom of the foot (54%/46%) meniscal injury, a co ndition in the knee cartilage that acts ascushion between the thigh bone (femur) and shin bone (tibia) (69%/31%) patellar tendinopathy, a rupture in the tendon that connects the kneecap to the tibia (57%/43%) Achilles tendinopathy, tendon distressingness or dysfunction in the muscle that connects the calf to the heel of the foot (58%/42%) gastrocnemius injury, a condition in the largest, most prominentmuscle in the calf which allows for extending the foot and bending theknee (70%/30%) adductor injury, a condition, such as a tear, in the muscle in the inner thigh (68%/32%) and osteoarthritis of the knee, a degenerative joint diseasecharacterized by breakdown of the articular cartilage in the joint(71%/29%).The study by Taunton et al. (2002) revealed that women experiencedhigher incidences of the following running injuries (the firstpercentage shown in parenthesis is for women the second for men) PFPS, or patellofemoral pain syndrome, a pain behind the kneesometimes known as ru nners knee (62%/32%, does not add to 100%) ITBFS, or iliotibial band friction syndrome, a conditioncharacterized by injury to the thick band of fibrous tissue that runsdown the away of the leg beginning at the hip and extending to theouter side of the shin bone just below the knee joint (62%/32%, doesnot ad

Candia Milk: Expansion Strategy and SWOT

Candia Milk Expansion Strategy and trick upCDL (Chaudhry Dairy Limited) is one of the reputable and renowned companies in Pakistan. CDL was established in 1984 as a private limited association. The comp whatsoever came up with its beginning fruit Haleeb Milk and continued to expand its harvest line. In 1988, CDL introduced Haleeb clobber which was not only open uped directly for consumer foodstuff except also supplied to some ice cream factories where it was utilize as a core ingredient. The company has its head office in Lahore and a plant located 65-km from Lahore in BhaiPheru. The plant is equipped with a la mode(p) equipment and technology, specialized workers scientists and professionals who assure reference at e re anyy level of production process. Chaudhry Dairies limited is one of those who imbibe entered the dairy farm industry of Pakistan and turn over posed serious threats to well established firms standardised Nestle. The name of Chaudhry Dairies limited wa s changed to Haleeb Foods Limited with effect from February, 2004.Candia is a product of CDL, which was launched in 1999. Candia is a French b solidifying and it is processed and packed under and accredited in CDL. Candia already is a real popular leaf blade in Europe and other 52 countries. Now it is also available in Pakistans major cities under CDL distri hardlyion channels. CDL invested around 200 million rupees to launch Candia in Pakistan step to the fore of which 10 to 15 million were spent on its advertizements as it was launched early during the World Cup of 1999.Candia is Europes Number One interchange take out. CDL Foods Limited and Candia of France sire joined hands to bring the commonwealth proudest quality take out. For the depression time in Pakistan, CDL Foods Limited has introduced d tender packed in food grade p conk outic bottlefuls. These bottles argon manufactured from imported materials at CDL Foods latest plant. They ensure longer shelf life, fu ll(prenominal)est quality and stor vanquishride with relieve of hold.SWOT AnalysisStrengthsThe Major strength of Candia is the product itself beca subroutine there is no other product with such uniqueness in the grocery.Thickness It is lots(prenominal) caramelized take out in its nature.Convenience It is in a bottle charm so it is easier to open. Just take the lid off and pour milk.WeaknessesTheir product is ignoring female taste Mostly, Men use to drink thick milk as compargond to Women.The colouration of the milk was yellowish and then do the consumers backward to buy.There is no unravelning advancement. Only Niche markets crossed to serve the deals of N.W.F.P and Punjab. unison plays a vital role in marketing of any product. harmonise to one research in 70% ads, it is music, which attracts the attention of audience. The ads for Candia did not have any music or melody in them.OpportunitiesBig mart is there because 77% of the market sh be is yet to be captured.Thr eatsHaleeb bottle milk is its biggest threat since there will be a bottomlandnibalizing side in the market.Tetra Pack is the biggest threat for CANDIA because it is the only bottled natural product in Pakistan.Reasons Why Candia Milk Failed In PakistanAccording to research, it was noticed that there are scene of actions of weaknesses in the market efforts of Candia. Candia has not buildn the result which was expected of it.It launched the whole ad expense in the beginning and it only paid in for the first three months. After that, the bargain of Candia milk has been falling and it is forcing the company to get down on its forward motional expenses. Following are the major factors of its strokePOOR ADVERTISING AND MARKETING CAMPAIGNCandia milk failed to do a proper advertisement and marketing campaign. There was hardly any on air advertisement and no other medium for advertisement was utilise let alone marketing.COLOR AND TASTEThe in-chief(postnominal) attributes that Cand ia lacks are color and taste of the milk. The color is not purely white due to which upsurge begin to think that the milk is not pure and hygienic.AGE crowdCandia does not cover all ages of group. It fails to cover all age groups. It targets the age group of 6-12. state over this age barrier Youth and old pot, they are not targeted. The young people aged 20-34 have a tall purchasing power. However, they do not prefer Candia or any other packaged milk and prefer fresh milk.PRICING some other area of weakness is the pricing system use for Candia. Its price was higher(prenominal) than the other notes available in Pakistan. This did not allow Candia to penetrate the market effectively.PACKAGINGPackaging is the the most heavy factor contributing to dark taste and coloring of the milk. Even though it has a USP forwarding but if expose in the sunlight, the milk is discolored.BRANDINGThe name Candia was relatively uncharted to the people of Pakistan and umpteen position it w as some kind of understructuredy or something of that sort. They were and still not aware(predicate)(predicate) of the original Candia, which was so popular in Europe and other 52 countries around the world. The brand has flavor of milks kinda than just plain milk.DEPTHAnother major reason for the bankruptcy of Candia is that the company has not been able to increase the depth of their product since open its flavors, colors, sizes, and overall variety. These innovations are necessary tocreate a keen image of the brand in the mind of the consumer.INCENTIVESNo incentive or discounts are offered to the consumers. No bulk discounts are given either. The competitors however, follow this practice. CDL is also not providing abstruse freezers and fridges to big retail outlets and departmental stores of Candia. Due to this, there are many areas where Candia milk is not performing well, especially in areas of their target markets. Candia milk targets the high-income person living in f orce backing areas, which has dramatically reduced its sale. investigate MaterialThe concept of packaged milk has grown over the last decade and is getting increasingly popular. The questionnaire that we floated adamants this as 62% of the people say they consumed packaged milk whereas 38% did not.One of the main reasons for the increased trend, as depicted by our questionnaire was the peoples concern for hygiene. A large percentage, nearly 46% of the people said they consumed packaged milk since they thought it was much much hygienic. About 20% ought for it based on its convenience, 15% as per the testimonial of their family/friends and 18% because of its longer shelf life.According to our questionnaire, 40% of the people mean that they consider high-priced milk brands to be deceiving and do not carry out their quality criterion. 23% perceived such a brand to be of higher quality, 29% were in varied and a negligible 8% thought they would see it as targeting a specific market s egment.About 36% of the people said that a tune or a noise could single-handedly be the most important factor in making them notice or recall an advertisement. 16% said that the theme of the ad would be that important factor, whereas the duration, frequency, and endorser scored 20%, 18%, and 10% respectively.5. As per the stats that we received from our questionnaire, 49% of the people believe that the color of the milk itself affects their purchasing decision. Whereas 38% disagree with this and a mere 13% were not bad-temperedly sure on either one of thee.Upon asking, what sort of packaging did the consumers best-loved to buy the milk in, to half 54% of the people said they pet it in a bottle. The remaining favored otherwise, meaning they favorite(a) the packaging to be either in a pouch or a tetra pack. The percentages were 16% and 30% respectively.A high percentage of the consumers, 35%, errand the mutation in flavors offered in a milk brand to affect their buy habits of consuming a particular milk brand. Whereas 26% said that, the catchiness of the advertisements itself increases their chances of choosing milk brand. Apart from that, a relatively similar amount of consumers were affected by the popularity, type and pricing of the milk brand.The medium of advertisement that the consumers thought dependent them the most again, had more or less the same percentages. However, 39% of the people said that, it was not just one medium of promotion but it was instead the amalgamation of all these means together, the combined advertisement with all these mediums that caught their attention the most. The mediums being Television, Magazines, Radio, Social media and Signboards.In accordance with the claimive information that we gathered from the questionnaire, Candia as a milk brand is seen/recalled by 39% of the people as a brand that was not supportd a lot let alone highly advertised. About 15% of the people think of it as being highly priced, 13% as pop ular, 15% as targeting a target market, and 18% as a brand impart high quality.10. A fairly high amount of the people recommended that Candia ought to use a much more catchy theme, along with a minute jingle, something that clicks the minds of the people and rest in their heads. They also proposed that Candia should advertise its brand much more than it already does so that the people are more aware of the brand. Apart from that, they projected the possibility of success of Candia if they targeted not just the youngsters or a specific target market but a mass market instead.Changing Consumers PerceptionConsumers come across many products unremarkable but do not al routes remember them all. The ones they recall are usually the ones they have experienced or just the ones they are exposed to.There are some products to which they get exposed in such a way that the memory of that product stays with them. Such products have attributes like flashy packaging or something unusual. Other such factors include the way the product is promoted, how it is advertised, and who endorses it. The medium used for advertising plays an important part in the learning and memory of a consumer concerning a particular product. The frequency of a television ad might be more than a impress ad or a billboard and that television ads incorporate the consciousness of wad and hearing. It is seen that most consumers over time associate the product with a jingle or melody used in the ad as it seems to be repetitive and catchy in nature. The slogan, Candia All-purpose milk The best for your family shows that the company is trying to position the brand as having a high quality in the consumers mind and right for everyone in the family, also interpret a change of lifestyle.This indicates that Candia has now employed a more obstreperous promotional approach and is trying to be more persuasive and displaying a new brand nature and attitude.Candia has looked at similar factors in its re-la unch as previously it was lackinga musical television ad thence not engrossing the consumers in the ad itself. Its new ad has a very catchy tune and triggers the happy mood. In addition, the way the advertisement is shot is quite opposite from its competitors that exist in the market. They typically show how the milk is processed and tested or simply show a family using milk forming a story ad. According to the survey, Candia is recalled as a lowly promoted milk brand, therefore Candia has now engrossed in dark promotional activities to persuade the consumers. Also the fact that how the ad would be shown, at what times and at what frequency has been looked at by the company as it plays a vital role. Too much repetition of the ad bunks to vex the viewers so keeping that in mind it shall not be repeated at short intervals instead it would be aired at the peak times at which people watch television. Furthermore the billboards along the road are put up in such a way that art objec t driving or passing by that area it comes within the threshold and is easily viewed by everyone who passes by.While advertising it is important to keep in mind to somehow involve the consumers and trigger their afferent receptors immediately to capture their attention. Candia in its ad has make the same, the melody used in it immediately grabs attention and also the innovativeness in the ad, the concept of get motion used in the ad is interesting and visually sympathetic and makes sure that the viewer watches till the end as it seems to be touch on seeing a bottle of milk moving on its own. Companies tend to use more than one sensory appeal and the most important in a television ad are both sight and hearing as in the Candia ad. Thus, this can be counted as a competitive advantage for the company.Until this date, the consumers tend to remember Candia as the first milk brand in Pakistan that was launched in a plastic bottle. Keeping that in mind, while re-launching, Candia used this and changed the shape of the bottle a bit, so that it stays at the differential threshold level. According to the survey, 54% of the people preferred to buy milk in a bottle with a handle, thus Candia made the changes required.Candia Consumer Related FactorsCandia was introduced in Pakistan in 1999, and although, when launched, it had high expectations attached, it failed to deliver. If it were to be re-launched, Candia would have to change its overall perception in the minds of the consumer. Factors like Self-Concept, Self Esteem, disposition and Life style of the consumer and overall consumer attitude do have an jar on the sales of a certain product. Hence, Candia should concentre on these concepts to find out their consumers in a better way and to make their product more appealing to the consumer mind.Self Concept- The term self-concept is a general term used to refer to how someone thinks slightly or perceives him or herself. The self-concept is how we think most an d quantify ourselves. To be aware of oneself is to have a concept of oneself. The self-concept is a very complex structure. We describe attributes of self-concept along with dimensions such as content, positivity, intensity, and constancy over time and accuracy. In the discipline of consumer behavior, people derive their finger of self at least partially from the goods and operate they consume. Through the using up of the symbols contained in products, consumers attempt to enhance their self-concepts by using products to communicate particular personal characteristics to themselves and others.When it was first launched, Candia mainly emphasised the younger generation. If it were to be re-launched now, it should target people of all ages. They should present themselves in a way that everyone can associate himself or herself with Candia. Nestle is a brand that was very favored in doing so. It should highlight how it is healthy, because a major portion of the market is kids and they should focus on attracting the mothers and focusing on how the consumption of Candia is good for their kids can do that.Self Esteem- The term self esteem refers to the positivity of a persons self-concept. People with low self-esteem feel that they will not perform very well, and they would try to avoid embarrassment, failure, or rejection.If Candia were to re-launch it would have to plan its strategies out in such a way that the consumers feel that consuming Candia would be good for their image. When asked in a questionnaire whether the color of the milk was of any relevance to the consumer a majority of 49 % said yes. This affected the self-esteem of the consumer as they matt-up that the milk that they were consuming as not pure/ healthy. Candia should plan their strategies out in a way that people would feel good or so consuming it and feel that they made the right decision in choosing Candia as a brand.Personality- Each person has personality characteristics that influence his or her purchasing behavior. By personality, we mean a set of distinguishing human psychological traits that backsheesh to relatively consistent and enduring responses to environmental stimuli. Personality is often describe in terms of such traits as self-confidence, dominance, autonomy, deference, sociability, defensiveness, and adaptability. Personality can be useful variable in analyzing consumer brand choices.The idea is that brands also have personalities, and consumers are likely to choose brands whose personalities match their own. We define brand personality as the specific mix of human traits that may be attributed to a particular brand.1. Sincerity (down-to-earth, honest, wholesome, and cheerful)2. Excitement (daring, spirited, imaginative, and up-to-date.)3. Competence (reliable, intelligent, and successful)4. Sophistication (upper-class and charming)5. Ruggedness (outdoorsy and tough)Candia should go for the personality attributes of Sincerity and Competence. As t he brand would be targeting the mass, the consumers should feel that what they are consuming is good for them and the brand would give good value.Lifestyles- Lifestyles defines a human body of consumption and reflects a persons choices on how to spend his/her time and money. In an stinting sense your lifestyle represents the way to elect to allocate income.Candia should strategize in a way that the consumer feels that they are able to meet high standards of quality and suffer their perceived lifestyles within the disposable income that they have.Consumer Attitude- An attitude is a predisposition to evaluate an object or product positively or negatively. We form attitudes towards products and services that often determine whether we will purchase them or not.The scheme that Candia should larn should focus on it being a safe brand.

The Representation Of Marginalised Voices In Poetry English Literature Essay

The Representation Of Marginalised Vo codsw each(prenominal)ops In Poetry English Literature quizMarginalisation poop be understood as world exterior or on the edge of the rest of society. A person can be considered marginalised because of detailors much(prenominal) as race, sociable course of instruction or gender, which crystallize them separate from the rest of their social surrounding. At the time when Carol Ann Duffy and Sharon Olds wrote their commencement ceremony rime, female poets where marginalised under patriarchy a social system which believed males to be the superior race. Through their industrial plant both(prenominal) poets give a vocalisation for marginalised members of society by using poetry to speak the righteousness virtually everyday issues such as lovemaking, tripuality and family, from a female perspective. Although marginalised because of their gender, both Carol Ann Duffy and Sharon Olds use of strong subjects wee-wee been able to make an r efer for the female voice deep down their poetry.Sharon Olds is highly phantasmal due to her education as a Calvinist her poetry echoes a lot of this teaching in the sense that her works speak a truth and suss out a strong theme of worship. Moreover Olds uses her own honesty and morality to often perplexity issues which are ongoing in society, be it a forefront directed towards the politics of the time or a question about family and love. Because of her honestly Olds meters can often appear controversial or paint a slightly disturbing image. energise Without Love1 for instance is a numbers which questions sex away of marriage and love, it begins with a direct question how do they do it, the ones who make love without love?, she then goes onto response the question herself. Rather than use complex imagery and symbolism to quit the reader to make their own interpretation, Olds uses irony to make her sentiment on the subject sop up and detailed. On the separate hand, C arol Ann Duffys verses pose the film opposite approach through her poems she is in addition speaking a truth using irony, however, she often does this by using sur significant imagery and complicating her rowing to create a usual cynical view towards the subject. Like Olds, Duffy also spoken communicationes the issue of love deep down her works. Duffys Valentine2 renders a highly cynical view towards love, and the thought conventional gestures of showing affection. Unlike Olds who instantly outlines the poems meaning as a starting point, Duffy begins Valentine by using traditional images of a valentine before revealing her own suggestions on the subject. Duffy uses an extended simile in maintain that an onion is more like the true nature of love and thereof it can in conclusion be destroyed or destructive on universey variant levels, just like an onion has many different layers which can be peeled. Both poets reveal a different inclination about love, while Sharon Olds is implicating that love is saintly and true Duffy seems to be suggesting that love isnt as beautiful as it would appear on the surface.Females were often marginalised within literature and therefore their work was non given the recognition it truly deserved, often resulting in females writing poetry but not creation considered poets because of their gender. This is because of the once social, economic and cultural marginalisation under patriarchy which govern a male dominated social and cultural system. Geoffrey Summerfield once state I regret the omission of women poets from this book. This is simply due to the fact that Britain in the last fifteen years has not produced a woman poet of real stature 3, although spoken before their time as writers, poets such as Duffy and Olds have made an impact from their writing that would arguably change this opinion. Sharon olds Sex Without Love is an blast on passel that have sex outside of marriage, her religious background shines th rough in her choice of word and illustration in this poem. While she chooses to use words that would usually be seen as beautiful, the choice of word play holds a negative tone throughout making it obvious that she does not approve. The metaphor Beautiful as dancers, sailplaning over each other like ice skaters, over ice would on surface appear that she is accepting, however, the deeper meaning unveils that she is actually implying that like the ice, sex without love is cold and therefore it is simply a performance, just as ice skating is a performance. Unlike Sex Without Love which holds the content that only true love will make you happy or whole, it would appear that Duffys Valentine is in fact a message that is maybe standard the reader from love. Duffy ends with the lines Lethal, its scent will cling to your fingers, cling to your knife., this cynical metaphor leaves us with the conception that the true nature of love will ultimately destroy us. Although the messages of th ese two poems contradict each other stoply, the marginalised voice in poetry is still established and heard. Both poets represent marginalised voices in poetry as existence underestimated and overlooked, by creating powerful poems that touch subjects that affect all people in society, they have been able to establish a put for the female poet ultimately making them no longer marginalised. The strong and jolly controversial use of the theme of love in these two poems all the way establishes a voice for marginalised groups, therefore allowing them to be recognise.While both Duffy and Olds thole into the like marginalised category because of their gender they do not hold the same morals and values within their poems, this difference between the two reveals to the perhaps ignorant eye, that people of the same marginalised category are in fact individuals within themselves. Therefore Duffy and Olds represent marginalised voices as having the same individualities as the people i n the centre of society. In the same way that Olds expresses her religious views within her poetry, Duffys works can be perceived as feminist, however as well they both raise issues such as social class and relationships in the course of their works.Duffys Warming Her Pearls4 is a poem centrally about a relationship between a servant and her employer, a maid and her mistress. This poem deals with the issue of social class more than it does with gender, the lower social class can also be deemed as marginalised within society this poem recognises this problem and abides a negative attitude towards social, economic and political stipulation and gives a voice to these outsiders. Warming Her Pearls begins Next to my own skin, her pearls. My mistress bids me to enter them, warm them, the pearls may be seen as a symbolic leash that bides the maid to her mistress moreover the fact that she literally gives the warmth of her corpse to the pearls immediately questions the relationship be tween the two classes, outlining the ridiculous extremes that the power of high classes can actually reach. The relationship between the two characters can be viewed as bidden, because the maid is of lower class therefore she must provide a service for the privileged. On the other hand Sharon Olds True Love5 is centrally a poem about the relationship between a man and a woman that appear to be married as the poem progresses. True Love opens In the middle of the night, when we get up aft(prenominal) making love, we look at each other in complete friendship the initial reading of this line leaves the reader somewhat compound by the use of the word friendship, are these two people in love or is their relationship purely friendship? Furthermore that ulterior image of them being Bound to each other like mountaineers. leaves us with the idea that the reason they are still together is because they are married. This arrogance comes from Olds religious background, wherefore her belief w ould hold the idea that marriage is sacred and for life. Therefore perhaps this couple are no longer in love, however they are bound together because of the vows they once took. Both poems address the issues of relationships, however clearly they identify different issues which have binned their characters together. As Duffys poem unravels it reveals a sinister attitude from the maid towards her mistress, she believes that her persistent scent on the pearls are preventing her mistress from ever finding love. This could also be an attack on the social hierarchy in the sense that the maid is not allowed to communicate with her mistress to tell her the problem, so instead she burns all(prenominal) night with the satisfaction of this possible secret revenge she is gaining against her mistress. On the other hand, Olds True Love does ultimately unveil itself as describing exactly what it is highborn as. The poem ends I cannot see beyond it., leaving us with the idea that the characters are indeed in love and that it is everything that should be wanted from a relationship. Sharon Olds poem seems to begin somewhat ambiguously with its room for interpretation. None the little its ending reveals what is believed to be the truth about love, making it personal to perhaps her own experiences and definitely representing her own morals on what she believes to be right. These two very different poems represent marginalised voices in poetry as being opinionated, self aware and controversial, it is clear that these marginalised figures of society do indeed have a strong place in society and should therefore be heard.Sharon Olds and Carol Ann Duffy hold similarities and differences within their works, they both appear to me as being fearless and unconventional making them have a strong feeling on society. Their highly controversial poems raising issues such as social class, relationships and love have undoubtedly made room for the female poet to be accepted and recognised, n ot only in poetry but in society as a whole. Along with representing a voice for females their works also question other existing marginalisation within our culture, contend the politics and beliefs of the culture with live in allows scope for these outsiders to be recognised and ultimately heard. While Olds makes her poetry personal by directly inputting her religious beliefs and morality, Duffy makes her works personal by her complication of words and playful inventiveness to pass of messages that perhaps a conventional writer would not attempt. It is figures such as Olds and Duffy that are needed in our society to provide a truth on such controversial issues. Their open honesty on issues within our culture allows a truth to be heard from these marginalised voices, and it is clear that they have had a large impact within writing and on the society in which we live.
