An Unstoppable Convergence - Coursework Example This fact has formed, as Ralf Nader puts it, a kind of â€Å"duopoly† in American political life. Yet the point is that when one party loose, another party takes benefits from that. Along with the winner ideas and interests of this party are established on the highest level. And whoever comes to power, the result is always the same – â€Å"a corporate statist†, because one ideology can only win by restraining another. But that’s not how things naturally should go in the society. Nader says in Introduction, he had noticed that an ideology doesn’t matter in people’s everyday life. When he was young and helped with the local restaurant his father owned in Winsted, Connecticut and also, when Ralf Nader was hitchhiking, he noticed that people did not organize themselves according to their political views, but they have gathered together a common interest and common current thing they need to do. Therefore Nader stresses on the idea that ideologica l confrontation disappears when there’s a clear understanding what thing is the right thing to do. Behind an ideological explanation of the problem, there's always a common issue which can be found and shared by different parties adherents. In U.S. history there are a lot of examples of such cooperation, or â€Å"a convergence† as Ralf Nader puts it. That means it’s not only an interpersonal relationships’ characteristic. In 1982 a coalition against The Breeder Reactor Project in Tennessee was formed.

Thresholds Theory of Classical Psychophysics Essay Example for Free

Thresholds Theory of Classical Psychophysics Essay Discuss the thresholds theory of classical psychophysics and explain how characteristics of the perceiver are also important in determining the selection of stimuli. The theory that our human cognitive ability has thresholds from the conscious level to a non-conscious level which varies over time in strength. These thresholds are physical and are not defined, but generally are from those activities and thoughts that are the most active having a threshold that defines our active consciousness, down to those thoughts that are several thresholds away and not seemingly linked to our current awareness. The concepts behind the theory attempt to bring together areas of knowledge, including the commonly-held beliefs about short-term memory being limited to around 7 ideas. In an evolutionary sense, humans walk forward and have to plan their next steps. If humans are running, they may be planning, say, 7 steps ahead. This planning allows them to avoid having miss steps. They have to be able to analyze the results of possibly taking steps, and then keep changing their focus after taking a new step forward .In theory people are imperfectly able to keep focus on a small set of priorities. This imperfection may be the solution, though, for allowing new priorities to be considered. An example is if when shopping in a market holding a red scarf you like, someone yells from behind you â€Å"Stop that thief Help† You start to turn around. Your cognitive threshold will swap out your interest in scarves for an interest in this new distraction. You may: †¢Want to see the thief to avoid them †¢Want to see the person yelling to verify they are not joking †¢Want to see if you are near the thief, or possibly in danger In other words, our cognitive and analytical threshold allows us to act in our world and react for what could be labeled as basic evolutionary needs. The cognitive threshold changes over time, for reasons including: †¢mental capacity: fatigue, chemical or emotional impairment/enhancement †¢situational: the ability to think about running is higher when actually running, than when performing some other activity †¢training: learning enhances ability to manage and perform more in those areas being learned, such as language, music, sports, science, and other skills The Cognitive Threshold theory assumes that what is referred to as â€Å"unconscious† or â€Å"subconscious† thinking is essentially thoughts that take place at a different level of awareness. Perception is our sensory experience of the world around us and involves both the recognition of environmental stimuli and action in response to these stimuli. Through the perceptual process, we gain information about properties and elements of the environment that are critical to our survival. A number of factors operate to shape and sometimes distort perception these factors can reside: i) In the perceiver ii) In the Object or target being perceived or iii) In the context of the situation in which the perception is made. 1. Characteristics of the Perceiver: Several characteristics of the perceiver can affect perception. When an individual looks at a target and attempts to interpret what he or she stands for, that interpretation is heavily influenced by personal characteristics of the individual perceiver. The major characteristics of the perceiver influencing perception are: †¢Attitudes †¢Motive †¢Moods †¢Self-concept †¢Interest †¢Cognitive structure †¢Expectation 2) Characteristics of the Target: Characteristics in the target that is being observed can affect what is perceived. Physical appearance pals a big role in our perception of others. Extremely attractive or unattractive individuals are more likely to be noticed in a group than ordinary looking individuals. Motions, sound, size and other attributes of a target shape the way we see it. Verbal Communication from targets also affects our perception of them. Nonverbal communication conveys a great deal of information about the target. The perceiver deciphers eye contact, facial expressions, body movements, and posture all in a attempt to form an impression of the target. 3) Characteristics of the Situation: The situation in which the interaction between the perceiver and the target takes place has an influence on the perceivers impression of the target. The strength of the situational cues also affects social perception. Some situations provide strong cues as to appropriate behavior. In this situation, we assume that individuals behaviors can be accounted for by the situation, and that it may not reflect the individuals disposition Name and discuss briefly three (3) reasons why the memory of a healthy person may fail. Memory is one of the most important functions of the brain. Whether people realize it or not, their memories define who they are. There are many areas of the brain that help you create and retrieve memories. Damage or malfunction of any of these areas can lead to memory loss. Memory loss due to problems with specific brain areas may be different. It may involve only memory of recent or new events, past or remote events, or both. The amnesia may be only for specific events or for all events. The problem may involve learning new information or forming new memories. Mental or thinking abilities may still be present or may have been lost. Filling in the details with imagined events (confabulation), and disorientation to time and place may occur. Memory loss may be for words and thoughts only, or for the body can no longer perform specific actions calls motor action. Memory loss may also be partial, meaning failing to remember only a selected group of items. Self-esteem refers to how an individual feels about him or herself. Does someone view himself as a good person, worthy of good things? If he does, he probably has healthy self esteem. If an individual views himself as flawed and unworthy of praise or the respect of others, he probably has low self-esteem. Self-esteem motivates peoples actions as well as the decisions they make. Individuals with positive self-esteem are likely to believe that they measure up to others sufficiently. They are more likely to have the confidence to pursue different accomplishments, whether it is trying to do well on a test, trying out for a sports team, answering a question in class, or applying for a job. These individuals are not overly afraid of failure; they realize that failure is a natural part of life and whether they fail or succeed at something does not indicate their overall worth and ability as a person. There are several factors that influence self esteem. These include: Age: Self-esteem tends to grow steadily up until middle school, which may be due to the transition of moving from the familiar environment of elementary school to a new setting with new demands. Self-esteem will either continue to grow after this period or begin to plummet. Gender: Girls tend to be more susceptible to having low self-esteem than boys, perhaps because of increased social pressures that emphasize appearance rather than intelligence or athletic ability. When memories are stored in the brain, they cannot serve people unless they are retrieved. How do people retrieve memories? This usually happens when memories are challenged. For example, if someone asks a question, a person must attempt to retrieve information in order to answer the question. Sometimes the answer is easy; other times, a person takes time to answer it. The amount of time it takes to answer the question is connected to a persons awareness of what memories are stored. Sometimes a person is not aware at the time that he or she knows the answer, but later realizes that the information is there, ready to be retrieved. Sometimes, a smell or a sound can trigger a memory that a person did not know was there. Write short examples that are related to your daily activities using James-Lange theory, Cannon Bard theory and the cognitive theory James-Lange theory According to James-Lange theory theory, witnessing an external stimulus leads to a physiological reaction. Your emotional reaction depends upon how you interpret those physical reactions. For example, suppose you are walking in the woods and you see a grizzly bear. You begin to tremble and your heart begins to race. The James-Lange theory proposes that you will interpret your physical reactions and conclude that you are frightened. For an example, when I see a cockroach, feel like uncomfortable and move away from that place and my heart beet become fast by thinking of cockroach going to come near me. Cannon Bard theory Cannon-Bard theory states that we feel emotions and experience physiological reactions such as sweating, trembling and muscle tension simultaneously. More specifically, it is suggested that emotions result when the thalamus sends a message to the brain in response to a stimulus, resulting in a physiological reaction. For example: I see a snake I’m afraid I begin to tremble. According to the Cannon-Bard theory of emotion, we react to a stimulus and experience the associated emotion at the same time .The Cannon-Bard theory of emotion differs from other theory of emotion such as the James-Lange theory of emotion, which argues that physiological responses occur first and result and are the cause of emotions. Cognitive theory Cognitive theory is a learning theory of psychology that attempts to explain human behavior by understanding the thought processes. The assumption is that humans are logical beings that make the choices that make the most sense to them. Information processing is a commonly used description of the mental process, comparing the human mind to a computer. Pure cognitive theory largely rejects behaviorism on the basis that behaviorism reduces complex human behavior to simple cause and effect. However, the trend in past decades has been towards merging the two into a comprehensive cognitive-behavioral theory. This allows therapists to use techniques from both schools of thought to help clients achieve their goals.

Malnutrition Effects on Quality Of Life

Malnutrition Effects on Quality Of Life The focus of this assessment is quality of life and specifically this paper considers how malnutrition affects quality of life of community settings patients. According to the Scottish Governments publication Older people living in community Nutrition needs, barrier and interventions: a literature review, malnutrition is an umbrella term for undernutrition, overnutrition and imbalance diet intake (The Scottish Government, 2009). Malnutrition has previously been described in the various ways (The Scottish Government, 2009). However, for purpose of this assessment the following term will be used as defined by World Health Organisation (WHO) the cellular imbalance between the supply of nutrients and energy and the bodys demand for them to ensure growth, maintenance, and specific functions (see European Nutrition for Health Alliance, 2005). According to Saunders, Smith and Stroud (2010) 2 per cent of the UK population is underweight: Body Mass Index (BMI) is lower than 18.5 kg/m. However, they agreed that patients could be still at risk of malnutrition whatever their BMI is (Saunders, Smith and Stroud, 2010). Malnutrition, as well as other factors, has negative effect on the persons quality of life (The Scottish Government, 2009). In the UK, hospitals admission rate and mortality were greatest in patients with BMI below 20 (kg/m2) (Teo and Wynne, 2001). During nutrition screening survey in the UK various settings it was found that malnutrition doubles risk of mortality in the hospital patients and triples morality in elderly patients in hospitals following discharged (RCN and NPSA, 2009). Care Homes nutrition survey shown that 30 per cent of service users recently admitted to care homes were at risk of malnutrition (RCN and NPSA, 2009). According to Hickson (2006), malnutrition may be secondary to certain health conditions which is increasing risks for patients to become malnourished and those risk factors will be discuss later in this assessment (Hickson, 2006 and Teo and Wynne, 2001). However, European Nutrition for Health Alliance (2005) argued that malnutrition should be classified as independent disease (European Nutrition for Health Alliance, 2005), its due to undernutrition has a negative effect on all organs systems such as muscle-skeleton, cardiovascular, respiratory, gastrointestinal, endocrine systems and in addition, malnutrition has a psychosocial effect (Saunders, Smith and Stroud, 2010). It was found that undernutrition could cause following health conditions: in the healthy individuals and has advance exacerbation effects upon existent illnesses or injuries, reduced psychological wellbeing (increase anxiety, depression apathy, and loss of concentration and self-neglect) (Webb and Copeman, 1996 and Saunders, Smith and Stroud, 2010). According to Morley and Kraenzle (1995), balanced diet in general, is improving cognitive and memory performance in elderly (see Vetta et al, 1999). Chandra (1993) found that undernutrition is depressing organism immune function (see Webb and Copeman, 1996). It could be due to impaired cell-mediated immunity and cytokine, complement and phagocyte function this most commonly could lead to developing bacterial and parasitic infections and poor wounds healing (Saunders, Smith and Stroud, 2010). Malnourished patients have reduced muscle function, loss of cardiac muscle and reduce cardiac output, which results in impact on the renal function (Saunders, Smith and Stroud, 2010). The same individuals have reduced respiratory response to oxygen deficit by poor diaphragmatic and respiratory muscle function (Saunders, Smith and Stroud, 2010), increased risk of hypothermia, increase risk of falls and injuries (Webb and Copeman, 1996). In addition, redaction of fat and muscles mass are more obvious signs of malnutrition (Saunders, Smith and Stroud, 2010). According to Clayton (1991), malnourished elderly clients have a poor prognosis for recovery from following fractured femur, hypothermia, pressure ulceration and other conditions (Clayton, 1991). Fracture risk is high then calcium, magnesium and vitamin D intake is insufficient, during the weight loss bone mass is reducing as well (Saunders, Smith and Stroud, 2010). Early stage of malnutrition leads to loss of digestive enzymes that result in intolerance of lactose. The colon loses its ability to absorb liquid, electrolytes, and secretions of small and large bowels, which results in diarrhoea (Saunders, Smith and Stroud, 2010). According to Saunders, Smith and Stroud (2010), endocrine system is affected in malnourished patience. For example, chronic malnutrition will change the pancreatic exocrine function by reducing the insulin secretion (Saunders, Smith and Stroud, 2010). An author is currently working a nursing and residential care home for elderly patients as well as nursing and social recruitment agency, which is covering biggest part of the North West of England. Being allocated in hospitals and nursing homes the author noticed that patiences nutrition needs are being met well but where are still some areas for improvement. During the study carried out in the large the UK hospitals, it was found that 40 per cent patients admitted to hospitals were malnourished and two-thirds subsequently lost weight during their hospital stay (Teo and Wynne, 2001). During the service users meeting in the care home author working in, carried out in January this year, all 14 service users have stated that they are satisfied with food they are getting. However, two patients are still at risk of malnutrition. They have been referred to the GP for dietician support. The author strongly believes that nursing home is providing adequate food to the service users. Catering manager in the UK hospitals compare to chefs in nursing home have a small budge of  £11 to  £15 per patients a week (Teo and Wynne, 2001). The authors care home spends around  £30 per service user a week. However, in March 2007, Royal College of Nursing (RCN) carried out survey questioning nearly 2200 of their member relating nutrition issues. Survey has revealed that 42 per cent said the food provided for patients were below overage expectancy (RCN, 2011). In various reasons government and health profession organisations are now advising for routing screening of all patients admitted to any healthcare facilities (RCN and NPSA, 2009). In authors opinion, the main priority for addressing this issue is promoting patiences health and wellbeing and cutting financial cost. For example, annual financial cost of treatment malnutrition patience and any associated illnesses in the UK was estimated around 7.3 billion pounds. This figure includes treatment malnourished patience in the hospital setting, round 3.8 billion pounds and long-term care facility such as care home, round 2.6 billion (Elia M., et al., 2005). Causes of Malnutrition The author is currently looking after two service users who are scoring on the MUST. All two patients are elderly from 65 to 80 years old, with different background and health conditions. Patient No 1 is 87 years old female, was diagnosed with Alzheimers Disease, history of Transient Ischemic Attack (TIA), high blood pressure, right wrist fracture and Dysphasia. Current BMI is 19, which was stable after referral to dietician and commencing on oral supplements, than BMI was 17 back in the October 2010. Patient No 2 is 72 years old man, diagnosed with alcohol excess, CA oesophagus, Gout, Heart Failure. Current BMI is 23, which was stably increasing over past months following admission to nursing home, than his BMI was 17. Both patients have a poor appetite at present. Nursing homes staff cannot establish reasons for anorexia and BMI reduction in one patient. There are number of risk factors, which could cause malnutrition among elderly population. However, the most important factor leading to undernutrition is reducing of oral intake (Saunders, Smith and Stroud, 2010). Inadequate dietary intake is depending on various factors (Saunders, Smith and Stroud, 2010), which could be divided into three main categories: medical, social and psychological (Hickson, 2006). Firstly, age related changes such as changing in appetite or sensory (Teo and Wynne, 2001). Working in the care homes author noticed, an appetite is reducing with advanced age. Some people refused or preferred to omit meals, for example, one patient does not take breakfast, then the author asked her why she is not taken breakfast that patient replied that she is not a breakfast person. In addition, during the study carried out in USA it was discovered that elderly population are consumed less energy intake and follow more traditional eating pattern then younger population (Teo and Wynne, 2001). Poor appetite or anorexia is a most common factor leading to malnutrition in both young and old generation (Hickson, 2006). However, during the study commenced by Roberts et al (1994), it was found that ageing seemed to affect the ability to control food intake and weight lost will take longer to re-gains in elderly men compare to young (see Hickson, 2006). In addition, according to work of De Castro (1993), older people are less responsive to stomach contents than younger people, in term of hunger (see Hickson, 2006). Anorexia may occur as process of aging as well as during underlying illnesses (Teo and Wynne, 2001 and Hickson, 2006). Hetherington (1998) argued that changing in taste and smell could lead to loss of appetite through a perceived decline in the pleasantness of food. Loss of taste and smell could be associated with advance age and medications therapy mechanism of these changes are remains unknown (see Hickson, 2006). In authors care environment patients prefer to eat strong flavour and taste meals such as a roast meat with gravy, bacon, fish which are being served with traditional sauces or salt and vinegar to encourage patients to their food. According to Hickson (2006), a few works have been done to find out that improving the flavour of the food can improve diet intake and follow weight increase in hospitals and community healthcare patients (Hickson, 2006). A few patients do not like vegetables, intake of which have being recommended by NHS 5 a day complain based on the WHO (NHS, 2009). Patient No 1 and Patient No 2 do not have own teeth which is reducing ability to chew tender food. For both patients oral problems have not been reported. However, according to Finch et al (1998), National Diet and Nutrition survey, energy consumption was lower in edentate individuals compare to individuals with own teeth (see Hickson, 2006). Dysphasia or swallowing problem is leading concern in reducing dietary intake (Hickson 2006). The author has experienced that often care and catering staff do not understand the different between soft and liquidised diet and which diet should be given to each patients with dysphasia. Moreover, care staff that is responsible for feeding patients, needed assistant, every often do not understand the sings for swallowing problem. This concern has been addressed in the care home that the author is working in by appointed care staff for appropriate training section provided by Liverpool Primary Care Trust (PCT). According to research carried out by Mowe et al (1994), swallowing problem is showing up in 64 per cent of in-patience elderly (see Hickson, 2006). In addition, Gariballa et al (1998) argued that post Cerebrovascular Accident (CVA) patients with Dysphasia had a worse nutrition status then those patients without swallowing problems (see Hickson, 2006). The author strongly believes that malnutrition caused by various factors combined together such as old age and health or mental health problem (Saunders, Smith and Stroud, 2010). In the UK, it was estimated that around 8 per cent of patients with chronic diseases living in the community are malnourished (Teo and Wynne, 2001). According to Hickson (2006), diseases-related malnutrition is usually associated with cancer, physical disabilities, endocrinology disorder and respiratory disease, gastrointestinal disorders, neurological disorders, sources of infection and other psychological factors such as depression and Dementia (Hickson, 2006 and Teo and Wynne, 2001). Medical factors increase the risk of patient to become malnourish through, for example, nausea or vomiting, diarrhoea or constipation, anorexia and malabsorption (Hickson, 2006). Cultural factors or social (Vetta et. al. 1999) and food habits are also playing an important role in developing malnutrition as independent illness (Hickson, 2006). As example, an individual who had a long-term hospital stay or had no nutrition support while in the community would not used to have full nutritional meals. Moreover, individual who has been admitted to the authors care home used to take fast food or sandwiches at all the time while at home, instead of cooked meals. According to Hickson (2006), there are lifestyles and social risk factors for malnutrition in elderly people are lack of knowledge about food, nutrition and cooking, isolation and loneliness, poverty, inability to shop or prepare food (Hickson, 2006). Dementia has a great effect on individuals relationship with food (Alzheimers Society, 2011). Dementia patients or patients with low mental status appeared to lost weight due to reducing self-feeding ability, acute sense of smell and taste that is depending on severalty and progression of disease (Teo and Wynne, 2001). Berkhout et al (1998) has confirmed that weight lost in demented patients is caused by patients ability to feed them rather than by dementia as illness (Hickson, 2006). According to Incalzi et al (1998), study carried out for in-hospitals patients found out that cognition is causing impairment to ability or desire to eat (see Hickson, 2006). Progressive dementia is usually associated with uncontrolled weight lost and changing eating habits (Claggett, 1989 see Hickson, 2006). Nutrition screening and risk assessment In 2007, RCN commenced Nutrition Now campaign, which has a wide response from members of public as well as members of multidisciplinary teams. The RCN Principles for Nutrition and Hydration were published in 2007. That principals aim to help of all health professionals grades to improve nutrition and hydration of patience. This paper is highlighting three principles of nursing care: accountability, responsibility and management to improve the patience nutrition and hydration (RCN 2011). Nutrition screening pathway, nutrition risk assessment are widely used which assist nursing staff to indentify the risk of malnutrition or/dehydration and appropriate actions to be taken. Risk of malnutrition screening should be a routine process in all healthcare settings (RCN and NPSA, 2009). In the authors care home as required all service users are being screened for malnutrition on the admission and once a month or more often if required, using Malnutrition Universal Screening Tool (MUST) as recommended by government bodies and Care Quality Commission (CQC) as registration body. Part of the admission documentation is to collect and record patiences food likes and dislikes. According to Saunders, Smith and Stroud (2010), MUST is reliable and valid screening tool in diagnostic or prediction of malnutrition (Saunders, Smith and Stroud, 2010). However, nutrition assessment was only done for patients who have been referral to their GPs following scoring, weight loss of 1 to 2 per cen t per week, 5 per cent per month or 10 per cent over period of six months (Mitchell, 2003). According to RCN and NPSA (2009), purpose of nutritional assessment is details identification of nutritional status and for special dietary plan to be formulated and implicated (RCN and NPSA, 2009). In the authors care home, dietician or dieticians assistant based on the information provided by staff nurse on duty normally carries out the nutritional assessment. As far as author concerns, nutrition assessment should be done by care home nurses as they are working in close contact with patients and their families on the daily basis, know better persons food likes and dislikes. However, special nutrition trainings are not always available to the nursing home staff. This could lead to complicated nutrition issues not to be addressed as quickly as they should be due to community dieticians waiting time is usually 6 weeks. In the authors nursing home all necessary equipments are available such as weight scales and height measures. However, weight scales calibration has not been done which could lead to poor nutrition screening assessment (NPSA). After completing the MUST, the author and colleagues will formulate the personalised care plan for each patient in order to meet nutritional requirements. Nutrition care plan could be based on the information or guidance provided by dietician or other health professions. Treatment According to Hark and Morrison (2003), the nutrition needs of healthy older adults are mainly the same as for middle age adults (Hark and Morrison, 2003). The intake of food containing Calcium, Vitamin D, Folate, Vitamin B12 and B6 should be increased for the elderly population (Hark and Morrison, 2003). Protein intake recommendation is variable from 0.8 g/kg per day in the USA (Mitchell, 2003) to 0.75 g/kg in the UK (McKevith, 2009). However, according to Mitchell (2003), one established nutrition needs recommendation cannot be used for all ages population (Mitchell, 2003). In addition, patients lifestyle, height and weight should be taken in account (Mitchell, 2003). There are number of fundamental support of nutrition available at present such as enteral and parenteral nutrition support (Hark and Morrison, 2003). At this assessment only oral nutrition support (ONS) will be discussed. The aim of the nutrition support is to ensure an individual gets enough energy, proteins, macronutrients and micronutrients to meet patients nutrition requirements (Saunders, Smith and Stroud, 2010). Saunders, Smith and Stroud (2010) argued that provision of regular meals with better nutrition content, wide menu choice and assistant with feeding should be enough to meet nutrition requirement and reduce nutrition risk (Saunders, Smith and Stroud, 2010). Numerous studies show that nutrition support could reverse weight loss, only if underlying health conditions under control (Saunders, Smith and Stroud, 2010). However, not all patients react at the same way (Hickson, 2006). At what reasons care and treatment should take an account of individual needs and preferences (RCN and NPSA, 2009). In practice, knowledge of food preferences and past medical history, following personalised nutrition care plan, serving patients with small meals (Teo and Wynne, 2001) or using a small plate could encourage service user to finish all meal. Currently some of the UKs hospitals commenced to use red tray scheme for serving the meals to patients. A purpose of using red trays is to alert hospital staff that patience with red tray is at nutrition risk and need assistance or supervision with diet intake (Bradley and Rees, 2003 see Davis, 2007). Protection of mealtime scheme is also widely spread across the UK. The purpose of this scheme is to create an environment for hospital patients free from hospital activities and unnecessary disturbance during a mealtime. In addition, this scheme is to assist nursing staff with concentration on the meeting nutrition need of hospital patients (NS, 2007). People with Dementia could loss an ability to use cutlery that could lead to weight loss and malnutrition. Providing those patients with available finger food could improve nutrition status (Alzheimers society, 2011). Teo and Wynne (2001) argued that the possible benefits from using energy supplements in elderly patients have received little or no evaluation in clinical practice (Teo and Wynne, 2001). However, during the study carried out by Volkert et al (1996), it was found that patients consuming food supplement while in-patience and 6 months in community have develop positive nutritional status compare to group of patients without food supplements (see Teo and Wynne, 2001). The author has come across the situation then GP has refused to prescribe food supplement to one of the patience and recommended full fat milk instead. In addition, during controlled trial for six months in patients who have been discharged from hospital and prescribed ONS has no economic benefit. To compare, using ONS in community is costing more than using ONS in hospitals (Elia et al., 2005). However, malnourished patients using could be at risk of re-feeding syndrome, which could results in death (Saunders, Smith and Stroud, 2010). Re-feeding syndrome is associated with water retention leading to fluid overload due to decay of potassium, magnesium, phosphorus and sodium in blood plasma (Mallet, 2002). Saunders, Smith and Stroud (2010) recommended that during re-feeding saviour malnourished patients potassium, phosphate and magnesium should be prescribed and thiamine (for patients with history of alcohol excess) (Saunders, Smith and Stroud, 2010). Conclusion The UK elderly population is rising, currently about 16 per cent of the population is above 65 (Hickson, 2006) and by 2050 over 30 per cent European population will be over 60 which will result in prevalence of malnutrition to rise (European Nutrition for Health Alliance, 2005). Many changing associated with aging have been documented, however, how senescence leads to the health conditions, related to aging, is still unknown (Mitchell, 2003). It was found that ageing is leading to slow reduction of weight and modification in body composition. It is due to declines in bone, muscle mass and body cell mass. Bone mass reduced due to inadequate intake of Calcium and inadequate exposure skin to the sunlight to encourage production of Vitamin D (Sahyoun, 2002). In general, people are gaining weight until they 60th birthday and after gradually reducing weight, usually 10 per cent between 70 and 80 (Mitchell, 2003). Weight loss related to aging and malnutrition should be indentified during initial nutrition assessment. In addition, community healthcare is facing many concerns. Firstly, malnutrition remains under-recognized problem facing patients, their families and health professions (Saunders, Smith and Stroud, 2010). Secondly, according to, Hark and Morrison (2003) argued that there are no single physical or biochemical screening tools could accurate predict the nutrition status in elderly (Hark and Morrison, 2003). Food prices are constantly rising and ONS are costing too much to the local PCT. In the authors opinion, providing service users with good quality food, offer choice of menu and snacks between meals are solution to fight malnutrition. The significant role in education medical students and junior doctors in nutrition has widely recommended (Saunders, Smith and Stroud, 2010). However, inadequate knowledge in nutrition of nursing and care staff could increase risk of malnutrition (Saunders, Smith and Stroud, 2010). In the authors care home nutrition in elderly is not mandatory training for the care staff. Following this assessment, the author will provide relevant care staff with information on the nutrition in elderly service users. This could be achieved through supervision sections and face-to-face talks. Moreover, there it is possible, elderly population and their families should be informed about the latest nutrition recommendations related to their age, lifestyle and health conditions and should encouraged to apply those recommendations to individuals lives (Sahyoun, 2002).

Canterbury Tales :: essays research papers

Canterbury Tales as a whole was very interesting. It has introduced us to a way of life that we never knew existed. It also introduced us to a type of crude humor that we have never been exposed to. It has shown us a true side of life during the Middle Ages. We have learned many things already from our World History teachers, but to experience it first hand is a different story. To experience the jokes, the merriment, and culture opens the gates to a new world. I think that these tales have been very entertaining, and enriching. I liked all the tales that I have read. I think that Geoffrey Chaucer was right to record culture the way it is, and not have toned it down to fit the needs of religion. The culture is the way it is, and no one can change it, only to record it. Chaucer recorded like he saw it, with no bias or impure intentions. He was just an author trying to write a book, for people to read and enjoy. I think that the Miller's Tale was very interesting, and definitely showed us some of the crude humor that people in the Middle Ages liked to read about. Most of the crude descriptions, or would not even be allowed to be discussed in sex education class. It can be gruesome, yet it can also be romantic. The plot describes the two lovers, as trying to make love, yet her husband must be distracted. They scheme a clever plot to avoid detection, but a friend spoils the plan. It is a Romeo and Juliet version that is a bit twisted, and bent. The Reeve's Tale In the Prioress's Tale religious discrimination is a definite issue. It deals with the conflicts concerning Jewish, and Christian people. Although in today's times this religious conflict would not usually occur, it is still a minor issue. Most Christians do not despise Jewish people, and most Jewish people do not despise Christian people, in fact they seem to get along together pretty nicely. However in the Middle Ages people must have thought differently because this type of story would never be allowed in our library. However Chaucer has written the Tale in the way he felt that best expressed the times. The Pardoner's Tale had to do with some religious issues again. In this tale it discusses different types of sins, and tells a tale of a group of boy's sins.

Murder of Emmett Till Essay

Emmett Till was a fourteen year old boy who lived in Chicago. He was very outgoing and friendly with everyone he met. After his uncle, Moses (Moh-ss) Wright, came up to visit, he took Emmett and his cousin down to Money, Mississippi. Before he left, his mother informed him that life is very, very different for blacks in the South and the way he acted at home could not be the same as how he acted down there. He didn’t believe her warnings. As Emmett and his mother got to the train station Emmett ran for the train in haste as to not miss his ride. Mamie Till, his mother, yelled to him â€Å"Emmett, aren’t you gonna say good bye? What if I never see you again?† Emmett said, â€Å"Awhh mama.† Then he gave her a kiss on the cheek and handed her his watch so that she had part of him while he was away. She asked about his father’s ring and he said he was, â€Å"going to show it off to the boys† and was on his way without regard to his mother’s warnings. Money, Mississippi was just a stretch of road with a post office on one end and Bryant’s Grocery and Meat Market at the other. Bryant’s sold cool drinks to passing field workers and candy to the neighborhood children. So African Americans were often regulars. As Mamie had said, the south was like a whole other world compared to Chicago. In the south, when a white woman would walk down the sidewalk and a black man was walking towards her, he would have to get off the sidewalk and look at the ground because a black male can never look a white woman in the eyes. Blacks weren’t even allowed to enter through the front doors of white businesses. Moses Wright worked on a field picking cotton. He lived in a small shack on the plantation that he worked for. There were only three small rooms in the shack so everyone squeezed in to the available beds. Emmett had to sleep with his cousin in one room; Moses was in another and in the other room, Wheeler Parker, Emmett’s close cousin and the others. While there Emmet and his cousins would help Moses in the field. On August 24, the boys drove into town from the field and went in to Bryant’s Grocery to get candy and drinks. Emmett went in and purchased two cents worth of bubble gum and on the way out turned back to Carolyn Bryant, the wife of the owner of Bryant’s Grocery, and whistled to her. She was furious and ran out to chase the boys, so they got in the car and drove off to their uncle’s house. While driving home Emmett begged his cousins not to tell Moses of the events that occurred. After three days, the boys forgot about the whole scenario. On the fourth night, at about 2:30 am while everyone lay asleep in bed, Roy Bryant, Carolyn’s husband, and his brother J.W. Milam broke into the house. They went into the first room to find Moses sleeping and woke him, shinning a flashlight in his eye and holding a rifle to his head and asked where Emmett was. Moses pleads for them to leave the boy alone but they did not listen and went into Emmett’s room and kidnapped him. Days went by with no word, so as does most blacks when someone goes missing, they started to check around the Tallahassee River, to try to find his body. Days later, a young man fishing in the Tallahatchie reported Emmett’s body floating in the nearby weeds. When Moses went to identify the body, the only way he could verify that it was Emmett, was by his father’s ring that was on his finger. Both men were arrested and set to be tried in the Tallahatchie County Court in September of 1955 for the murder of Emmett Till. The friends of Roy Bryant and J.W. Milam as well as other white families collected money to buy every lawyer they could for the two. When it came to the trial the defenses main strategy was that the body could not be identified as Emmett Till. They claimed that Roy Bryant and J.W. Milam let him go alive. Any Black people that came forward with information for the prosecution mysteriously disappeared so most remained neutral to avoid having the same fate. The two men were acquitted and set free, Mamie Till sent to higher courts and even President Eisenhower, who all refused to investigate further. After the trail Roy Bryant and J.W. Milam sold their story about what they did to Look Magazine. They made Emmett carry a 75-pound cotton-gin fan to the bank of the Tallahatchie River and ordered him to take off his clothes. They beat him nearly to death, gouged out his eye, shot him in the head, and then threw his body in; with the cotton-gin fan tie around his neck with barbed wire, his body sank into the river. After the story was published and the government did nothing about it, Mamie Till and All African Americans in America, realized the magnitude of their predicament. They knew that their rights as humans were at risk. Thus, the murder of Emmett Till became renowned as the spark that began the Civil Rights Movement.

NASAs Trip to Pluto essays

NASA's Trip to Pluto essays In January of 2006, an Atlas 5 rocket will be launched in order to look at Pluto and its moon Charon. The mission is called New Horizons. The model 551 Lockheed Martin-built Atlas 5 will have five strap-on solid rocket boosters, a single engine Centaur upper stage and the larger five-meter-diameter fairing. It will not reach its destination until 2015. It will be the first exploration of the third zone of the solar system. NASA is racing to gather data and pictures about this region of the solar system before the planet's atmosphere freezes out for two centuries from Pluto moving further from the Sun. There is very little solar energy that lands on Pluto and it has been impossible to get clear shots of the planet with the most powerful telescopes. There is very little known about the planet. Pluto's atmosphere is an enigma, its surface vaguely understood. Astronomers don't know how or under what circumstances Pluto formed. During this mission, a large interest is research of the Kuiper Belt. NASA would also like to gain further understanding of whether Pluto is a Kuiper Belt Object KBO or Planet and research what properties it atmosphere has. They will also research Pluto's other moons and why they might exist. They will study the global geology and morphology, map the surface composition, and characterize the atmosphere of Pluto and its escape rate. They will also studying time variability of Pluto's surface and atmosphere, imaging and mapping areas of Pluto and Charon at high-resolution, characterizing Pluto's upper atmosphere, ionosphere, and energetic particle environment, search for an atmosphere around Charon, refine bulk parameters of Pluto and Charon (such as mass and diameter), search for additional satellites and rings, and characterize one or more KBO's. The general population is also excited about the prospect of finally having a clear picture of the planet that is sometimes the most dista nt and some...
