Questions: 1.Why is a policy cycle an appropriate tool for developing a new policy? 2.How is a health policy different to a government policy document? 3.What are key sociological issues and how do they determine a persons state of health? 4.What is meant by the term power in policy development and change? 5.What policy considerations should be included in a national obesity health campaign? Answers: 1.In order for health care to be efficient and equal for each and every socio-economic group, health policies are an irreplaceable tool. According to Harold lasswell,policy making can be defined as the process of identification, agenda setting, adoption, implementation, appraisal and policy evolution. And the policy cycle is a heuristic tool that serves as a organizing device for the authority to design and implement health policies. There are various strengths that the policy cycle provides to the entire construct, first and foremost, it has to be mentioned, the cycle in the policy cycle conveys a movement in the process of ideas and resources in the iteration of the policy making. According to the Buse, Mays and Walt (2012), the policy cycle provides a routine for the policy makers to follow that does not finish with just a decision but It follows through to implementation and evaluation of the entire process. On a more elaborative note, it has to be mentioned that the policy cycle provides a set of normative values that simplifies the complex procedure of policy making into different steps, so that acute emphasis is given to the each and every area of need in the policy procedure (Buse, Mays Walt, 2012). Along with that, it has to be mentioned as well that the process of the public health policy making is the exploration of a variety of information and resources regarding the needs of different demographics and patient population. The policy cycle provides the policy making authority with the opportunity to synthesize the existing knowledge and exploring resources so that the policy addresses each and every public health priorities and the areas of the need. Hence, it has to be mentioned that the concept of the policy cycle provides a reasonable and simplified step by step procedure or framework that defines the activities following which a successful procedure of designing and implementing a public health policy (Hannigan Coffey, 2011). 2.A health policy can be significantly different from the regular government laws and policy documents. First and foremost, it has to be mentioned in this context that the health care can be easily considered one of the greatest public service needs in the society. It has to be mentioned that in many nations, health sector can be considered a very important part of the economy. According to the Solar and Irwin (2010), health policy in case of many developing nations is serves as a sponge that demands and absorbs a large amount of national resources than any other government of tax funded sector of public service. On the other hand there are other schools of thoughts regards the public health policy are the drivers of the economy, the health policies invest in innovative new biomedical technologies and different infrastructures, improving the health of the population which in turn improves the life expectancy and credibility of the society. Hence, the most important difference between the health policy and government policy document is the priority funding that both of the sectors receive. A government policy document on the other hand provides the details regarding the policy commitments of the government and all the required initiatives that is needed to be taken in order for the nation to reach all the ICT or developmental goals. A regular government policy document emphasizes on all of the developmental and socio-economic growth goals instead of focusing on just the health care needs of the nation. Hence a government policy document can be in health, but it can also be in environment, education or trade as well. On a simpler note, a government policy is generally a public policy related to any of the area of need of the general public, on which the government will decide and commit what it will do and will not do (McConnell, 2010). 3.There are various inequities and disparities that has a profound effect on the health status of the different social groups, both the accessibility and the health status generally varies across the social gradient. First and foremost, the life expectancy lowers further down the social ladder, with lower financial strength and employment status as well. It has to be understood in this context that the impact of occupational class is very high in health throughout the life. According to the research, there is almost twice the risk of severe health adversities as the occupational status lowers across the social gradient. Poor occupational status has a significant impact on the lifestyle as well, which in turn imparts the detrimental impact on the health status and the poor nutrition increases the vulnerability to various diseases. Stress is the second most important sociological issues that has a major impact on health outcomes, according to Marmot et al. (2012), long term stress can give rise to health concerns like anxiety, hypertension, insecurity, paranoia and can even lead to other impactful sociological issues like low self esteem and social isolation. This psychosocial issue deteriorates the mental health and leads to reduced life expectancy by facilitating diabetes and cardiac diseases. Early life is the fourth social issue, where the poor maternal or child health and nutritional status affects the life expectancy and health of the children on a long term basis. The fifth issue is social exclusion, and coupled with poverty there are various health adversities that can even lead to fatal consequences like premature death without support. The sixth social issue professional stress and work life relations can also have a detrimental impact on health causing anxiety, hypertension and cardiac diseases. On the other hand, simultaneously with extreme workload and professional stress, unemployment can also lead to anxiety and depression and can cause health risks (Althaus, Bridgman Davis, 2013). The lack of social support has been found to have a significant impact on the health outcomes as well, lower the standards of the community care and social support services, worse is the health outcomes of the concerned community. Addiction is another severely impactful social issu e that has a huge impact on the health outcomes of a community and enhances risk of various health concerns like respiratory disorders, cancer, cardiac problems and substance induced psychosis as well. Lastly, the food and transport are also social issue with great impact on the health outcomes, it has to be mentioned that with diminished nutritional status and lack of cycling, walking and public transports in a nation can indirectly pave way for many non-communicable health risks (Braveman Gottlieb, 2014). 4.Power can be considered as the significant construct that moves each and every sector of a human society, and the health policy sector is not an exception to that rule either. There is a distinct role of power manifestation in the policy making procedure; both in design and implementation. According to the policy cycle, there are several steps to the construct of a policy and power plays a profound role in all of the different steps of the policy making procedure. It has to be understood that a policy making can be considered as a process that involves different groups competing with each other depending on their individual interests, hence the manifestation of the concept of power is extremely crucial for the final verdict to be made (Wildavsky, 2017). In case of a government policy, the greatest decisive power is with the government authority without any doubt, and the government body has the total controlling power over the entire procedure as well. On the other hand, there is n on-decisive power in the policy making scenario as well, it is attributed to the ability of any powerful group to keep threatening issues below policy radar for personal gain as well. Along with that, power can also be exerted in this scenario by any influential group of social activists to exercise thought control over a huge population involved with a policy making or implementation. Hence, it can be mentioned that power is a multidimensional construct on the context of policy making and implementation and there are different sets of impact on the policy design and implementation procedure of the different domains of power in this scenario (Geyer Rihani, 2012). 5.Obesity can be considered easily as one of the greatest health concerns of the developing nations and considering the Australian health demographics, obesity is a rising concern. According to the report by the Australian institute of health and welfare the obesity statistics in the Australian demographics is 2 in every 3 people, and hence there has been a 5 to 10 % hike in the burden of different non communicable diseases that are linked to obesity. Hence a national health campaign for obesity in Australian context should consider a number of different related topics. First and foremost, the prevalence and incidence rate of obesity in the nation will needed to be included in the process, along with that the risk and vulnerability of the obese and the people in the obesity threshold to different cardiac and renal co-mortifies will need be calculated and considered in the obesity campaigning (Grantham et al., 2013). Lifestyle patterns play a very important role in the obesity statist ics of the Australian people, the natives with a more or less sedentary lifestyle and lack of obesity awareness, are far more at risk to obesity. Hence the lifestyle patterns and screen time of the target population will also need to be included in the campaigning procedure. The diet speaks volumes regarding the health status of a particular community and hence the diet pattern and consumption junk food is the next consideration for the campaigning. Lastly, awareness and literacy about obesity prevention and healthy lifestyle will needed to be considered in the policy consideration for the campaigning. The accessibility and reach of the obesity prevention and health promotional campaigning across different disadvantaged groups will determine the success of the campaign hence the policy must ensure maximum inclusion for all socio-economic groups (Magnusson, 2010) References: Althaus, C., Bridgman, P., Davis, G.

The Changing Meaning of School

The Changing Meaning of School The Changing Meaning of School The Changing Meaning of School By Maeve Maddox Since Shakespeare’s time at least, children have been portrayed as being reluctant to go to school: the whining school-boy with his satchel And shining morning face, creeping like snail Unwillingly to school.  - As You Like It, II:vii,148-150. That’s a sad fate for school, a word that originated in the context of enjoyable leisure time. Our word school comes from Latin schola, â€Å"learned leisure.† Schola was free time during which educated men could sit around and talk about ideas. The talk might lead to lecturing and arguing, so from meaning â€Å"free time for talking about ideas,† schola came to mean debate, dispute, lecture, dissertation. More and more definitions were added. A schola could be â€Å"a place where learned disputations are carried on.† Then, the followers of a favorite lecturer or philosopher were called â€Å"a schola.† Note: School in the expression â€Å"a school of fish† derives from Middle Dutch schole, â€Å"flock of animals.† In modern English, school has numerous meanings and occurs in several idioms. School can mean any of the following: An establishment or institution for the formal education of children or young people. The building or set of buildings used by a school. A place, environment, experience, etc., which forms or develops a persons character or behavior. A group of people who follow or are influenced by the teaching of a particular person, or who share similar principles, ideas, or methods. A group of people who share a particular opinion, practice, or custom. A particular type of doctrine or practice as followed by a group of people. An institution in which instruction of a particular kind is given. A department in a college or university. Here are a few examples of these different uses: A painting of Mary Stuart by an unknown artist of the School of Clouet hangs at the Hermitage, St. Petersburg. Spenser  earned his degree  in the  school of hard knocks, so he is ready when a Boston university hires him to recover a rare, stolen manuscript. You have to understand,  hes definitely old school when it comes to  understanding different cultures. This is a discussion of Marxism-Leninism as a  school of thought as opposed to a political practice. The Colorado School of Mines Board of Trustees announced that  Paul C.

Whether music is allowed according to the islamic shari'a Essay

Whether music is allowed according to the islamic shari'a - Essay Example It is imperative to be aware of what our religion teaches us about music, acceptance and tolerance of music, and to what extent we are permitted to listen to music. For this we need to refer to the Quran, Hadith and sayings of the Rightly Guided Caliphs and Prophet’s companions. According to these sources, music has been termed as ‘haraam’ in our religion. Interpreters of the Holy Quran have identified the term â€Å"lahwal hadith’ as listening and singing songs, buying music and buying instruments for amusement. Sayyidana Abdullah Ibne Mas`ood, a close companion of the Holy Prophet was inquired the meaning of the phrase â€Å"lahwal hadith’ and he answered, â€Å"I swear by Him besides whom there is no other God, that it refers to ghinaa (singing), (Inter-Islam, 2001).† It is believed that he repeated this statement thrice and his views have been seconded by the Four Caliphs, the prominent Sahaba and other reliable personalities in Islam. Music is forbidden and also regarded as a major sin in the Muslim religion. Playing of musical instruments is also a major sin hence it is haraam to play the guitar, piano, drums etc. Imam Ali ibne Musa Reza says, â€Å"And to be engrossed in musical instruments is also one of the great sins,1 (Bhimji, Saleem).† A verse from Surah Luqman in the Holy Quran is often offered as a proof of prohibition of music, ‘And there are among men those who purchase idle talk in order to mislead others from Allahs path without knowledge, and who throw ridicule upon it. For such there will be a humiliating punishment.† The word â€Å"idle talk’ here refers to the word ‘lahwal hadith’ which has been discussed earlier. This word has been interpreted in two more ways but they refer to shirk (polytheism) and diverting people from Allah’s worship which takes us to the same idea of engaging in prohibited activities (Bilaal, 1986,

1.The purpose of this is to examine current fiscal and monetary policies by the UK government and their effectiveness and impact on GDP and interest rates using graphical and regression analysis - Coursework Example In essence, the IS-LM model is a macro-economic tool demonstrating the relationship between interest rates and real out-put in the goods and services market and the money market. It is a combination of goods market and money-market equilibriums. The aggregate model describes general equilibrium situation in macro-economy. IS-LM model is based on assumption of fixed price level. This implies that general price level will not abruptly adjust when economic conditions alter. Suppose there is an increase in demand. Given supply, the increase in demand should produce an increase in price level (and in quantity exchanged within market). The period within which it stays unaltered is short run. The time series traits of variables using three tests reveal most of variables are stationary with intercept. This captures non-zero mean under alternative hypothesis. Nonetheless, many variables are non-stationary with constant and deterministic time trends. This captures deterministic trends under this alternative. The variables may therefore be regarded as stationary and does not require differencing. The IS Curve is representative of the equilibrium points in goods market, that is, the combinations of r and Y for which investments (I) are equal to savings (S). It is important to remember that investment is negatively related to real interest rate and is non-dependent on level of real output/income. Saving has a positive relationship to real interest rate and further increases with income. Various scholars have argued that the European sovereign debt crisis is traceable to the nineties whereby the 15 member states then, deliberated on the benefits of establishment of a common regional currency (Sgherri & Zoli, 2009). Despite agreeing on certain debt targets, there are many instances where member states out-rightly failed to adhere to the ceiling limits. Despite this obvious violation, no financial sanctions were imposed on

The sport discipline

The sport discipline In sport disciplines that rely on speed endurance or strength endurance, anaerobic glycolysis provides the primary energy source for muscular contractions (Zajac et al., 2009) During high intensity exercise there is an increase of hydrogen (H+) ions in the mitochondria (Pilegaard et al., 1999). The metabolic demands of high-intensity exercise are met primarily by glycolysis, which is the non-oxidative breakdown of glucose (Gosselink et al.,1995). This is caused when the demand for energy exceeds oxygen supply or utilisation rate. As a result the cell mitochondria cannot process all hydrogen ions joined to its carrier NADH. The hydrogen ions begin to accumulate in the cells which decrease the pH of exercising muscles and cellular acidosis occurs (Brooks 1985). To maintain availability of NAD+, and to prevent acidosis, excess Hydrogen ions are temporarily bound with pyruvate to form lactic acid. Rupp et al., (1983) states that at rest arterial blood pH is ~7.4, while venous blood pH is normally slightly lower (~7.3-7.35) and muscle pH is ~6.9. It is also suggested Exhaustive exercise decreases pH ~0.4 pH units in both blood and muscle, and is highly correlated to increased blood lactate concentration. Similarly, blood and muscle bicarbonate ion concentration decreases linearly as a function of increasing lactate ion concentration. This increase in hydrogen ion concentration interferes with anaerobic metabolism by disrupting the activities of key enzymes; it is also associated with reduction in ATP production, lipolysis, and muscle tension (Monedero Donne. 2000). Harrison and Thompson (2005) state that the increase in acidity ultimately inhibits energy transfer and the ability of the muscles to contract; forcing the athlete to decrease the intensity of exercise. Gollnick et al., (1986) suggests that this is because hydrogen ions displace calcium from troponin, which causes interference in muscle contraction. It is the production of these hydrogen ions and the decrease in pH that causes the effects associated with fatigue (Robergs, 2004) Acidemia also has an effect on the cardiovascular system, by reducing or stops the responses of the heart to stimulation of sympathetic nerves and slows the heart rate due to vagal stimulation (Hainsworth 1986) CO2 levels and the pH of the blood perfusing the cephalic circulation has an effect on efferent signal activity (Soladoye et al., 1985) The bodys first line of defence to prevent acidemia are naturally occurring chemical buffers such as a weak carbonic acid and sodium bicarbonates (Zajac et al., 2009) A buffer is a solution containing substances which have the ability to minimise changes in pH when an acid or base is added to it (worthley 1977) The intracellular buffering system, includes amino acids, proteins, Pi, HCO3, creatine phosphate (CrP) hydrolysis, and lactate production, binds or consumes H_ to protect the cell against intracellular proton accumulation (Robergs et al., 2004) Explain gradient In the bicarbonate buffer (HCO3) system the chemical equilibrium between carbonic acid and bicarbonate act as a ph regulator. Buffering results in H+ ions being drawn out from the muscle cells into the blood due to a concentration gradient. This process reduces the acidity within in the muscle cells (Lambert et al., 1993). If the [H+] in blood begins to drop then the pH raises, more carbonic acid dissociates, replenishing hydrogen ions. When [H+] rises, the bicarbonate ion acts as a base and removes the excess hydrogen ions lowering the pH (Mcnaughton et al., 2008) During buffering NaHCO3 in plasma exerts a strong buffering action on lactic acid to form sodium lactate and carbonic acid. An additional increase in [H+] from carbonic acid dissociation causes the dissociation reaction to move in the opposite direction to release carbon dioxide into plasma. (McArdle et al., 2007) Hydrogen ions, carbon dioxide, and oxygen are detected by specialized chemoreceptors in the brain. Inside cells, carbon dioxide (CO2) combines with water (H2O) to form carbonic acid (H2CO3). The carbonic acid breaks down rapidly into hydrogen ions and bicarbonate ions. Therefore, an increase in carbon dioxide results in an increase in hydrogen ions, while a decrease in carbon dioxide brings about a decrease in hydrogen ions (West 1995) chemoreceptors in the medulla detect the raised level of carbon dioxide and hydrogen ions. They send afferent signals the inspiratory center, which immidately stimulates veltilation to eliminate excess carbondioxide (McArdle et al., 2007) State how buffers work, conversion of co2 Hawthorn (1986) states that in the short term the most important buffer in the body is haemoglobin as it produces the smallest change in pH per given amount of acid, showing that it is most effective in retaining equilibrium. In the long term the most important buffer during exercise is the ventilatory buffer system in combination with bicarbonate. As the lungs remove excess CO2, reduced plasma CO2 levels accelerate the recombination of H+ and HCO3, lowering free [H+]s in plasma (McArdle et al., 2007) When the buffering capacity within the cell is exceeded, lactate and hydrogen ions diffuse outside the cells (McNaughton, 1992) thus reducing [H+] in muscle cell, this however leads to a higher H+ gradient in the blood (Robergs et al., 2004) resulting in an increased acidic environment. The ability to tolerate high-intensity exercise is limited by the bodys ability to counteract decreases in intracellular (muscle) and extracellular (blood) pH through its intrinsic buffering systems (Gosselink et al.,1995) What is Sodium Bicarbonate Lambert et al., (1993) states that Sodium bicarbonate is an alkalising agent that reduces the acidity of the blood by the process of buffering. Sodium bicarbonatebuffers the acidity from lactic acid that is created by anaerobic metabolism. This allows prolonged maintenance of force or power (Montgomery and Beaudin 1982) Sodium is an electrolyte that helps increase or maintain blood volume, creating a larger buffering space for muscles to excrete the extra acidity created by high-intensity activity. Benardot (2006) has suggested that the sodium in the sodium bicarbonate may actually be more useful than the bi carbonate. Potteiger et al. (1996) tested the effect of sodium citrate on 30-km cycling performance. Performance times averaged almost 3% faster than those in the placebo condition, showing the effectiveness of sodium and its effect on performance. Bicarbonate serves a crucial biochemical role in the pHbuffering system by accepting hydrogen ions from solutions when they are in excess and donating hydrogen ions to the solution when they are depleted, keeping a constant state of homeostasis. (Robergs et al., 2004) This process reduces the acidity within in the muscle cells. The process of buffering could therefore result in delayed fatigue and increased muscle force production. (Lambert et al., 1993) Despite an increase in extracellular bicarbonate, studies show that the sarcolemma is not permeable to bicarbonate (Mainwood Cechetto 1980). This suggests that H+ ions are not buffered inside muscle cells. Extracellular bicarbonate concentration results in greater H+ efflux to the blood (Mainwood Worsley-Brown. 1975) More about why Thus it has been reasoned by physiologists that by increasing bicarbonate reserves, the bodys extracellular buffering capacity will allow hydrogen ions to diffuse from the muscles at a faster rate. The benefit from sodium bicarbonate supplementation would therefore be a delayed onset of fatigue during anaerobic exercise (Cairns, 2006) In the early 1980s it was suggested that ingestion of NaCO3 could be effective in improving short-term exercise performance. Wilkes et al., (1983)compared the effects of NaCO3 and a placebo in six competitive 800-m runners. The bicarbonate was givenover a two-hour period at a dose equivalent to 21 gm for a 70-kg person (0.3 g per kg of body weight).The athletes completed a competitive 800-m race. Average performance was 2% faster in the bicarbonate condition than in the control or placebo conditions. In a similar study, but using a higher dose of sodium bicarbonate (0.4 g/kg, or 28 gm for a 70-kg person),Goldfinch et al. (l988)investigated the 400-m race performance of six trained runners.Athletes competed in pairs to simulate real competition. The performance of the bicarbonate group was 2% better than the control and placebo, which were not different from each other. The time difference was equivalent to a 10-m distance at the finish. Muscle biopsys on athletes have shown that after bicarbonate loading, the less acidic your blood pH and also less acidic your muscle pH. (Bouissou et al., 1988) Other studies Lactate production acts as both a buffering system, by consuming H+, and a proton remover, by transporting H+ across the sarcolemma, to protect the cell against metabolic acidosis. (Robergs et al., 2004) Katz and Sahlin (1988) states that rapid the increase in the production of lactic acid and the free H+ can be buffered by bicarbonate causing the nonmetabolic production of carbon dioxide (CO2). Consecutively the raised blood CO2 content stimulate an increased rate of ventilation causing the temporal relationship between the lactate and ventilatory thresholds (Stringer et al., 1992). Thomas et al., (2005) state that Lactate concentrations increase post exercise after NaHCO3 ingestion. This is common amongst studies testing the effects of NaHCO3. Raymer et al. (2004) suggests that at the point of fatigue, muscle [H+] does not decrease with sodium-bicarbonate ingestion. However the acidosis threshold increases, meaning that during induced alkalosis, muscle acidosis is lower at the same muscle workload. This is congruent with Cairns (2006) who stated that NaHCO3 delays onset of fatigue during anaerobic exercise. However there are potential negative side effects from taking sodium bicarbonate include severe gastrointestinal distress and nausea; this should give athletes reason to be careful before taking this potential ergogenic aid (Applegate 1999). These risks can be reduced through appropriate dosing and timing RPE and anticipation, if RPE is reduced then you should go faster How bicarb affects perceived exersion How other mechanism so regulating ph and mayb central gonenor afferent and efferent pacing algorithm However it has been suggested that NaHCO3 ingestion alone may not increase performance and other mechanisms may regulate performance for example the Central Governor model. The central governor model suggests that the brain is contently monitoring biochemical changes in the body through afferent and efferent signals and regulates them accordingly. This safety mechanism is in place to regulate and possibly stop exertion to prevent damage to the cells. This would suggest that the reason athletes are able to exert for longer is that the afferent signals such as pH levels in the muscle allow the brain to exert more without the risk of damage. Studies giving evidence for this argument include studies by Kostka Cafarelli (1982) have suggested that RPE during exercise maybe influenced through manipulation of acid-base status, suggesting that shifts in [H+] are linked to sensory processes (Renfree 2009) Ingestion of NaHCO3has been demonstrated to reduce RPE during supra lactate threshold (>LT) intensity exercise (Robertson et al 1986). This is congruent with finding from Renfree (2009) who found that Power output was higher (P Robbertson et al 1986 Applegate, E (1999). Effective nutritional ergogenic aids.
