An experiment to show Essay To see whether there is a relationship between the surface area and the diffusion rate Hypothesis I predict that the smaller blocks of agar will turn clear, or diffuse first, as it has a smaller surface area. This is because there is less surface area and volume for the sulphuric acid to diffuse into. Apparatus   Three sizes of agar, 20x20x20mm, 20x20x10mm, 20x20x5mm 40ml of sulphuric acid [80ml per beaker] 3 100ml beakers   Tile used for placing the agar   Tissue to wipe off the sulphuric acid off the agar   3 scalpels   Ruler, measurable in mm. Stop clock Method 1. First, cut three pieces of sulphuric acid in the following sizes 20x20x20mm, 20x20x10mm, 20x20x5mm, as accurately as possible 2. Next, fill the three beakers with 80ml of sulphuric acid each 3. Then, prepare the stop clock, and make sure it is has been reset 4. After, place the three blocks of agar into the sulphuric all at the same time, as well as starting the stop clock once the agar is in the sulphuric acid. 5. Carefully stir the three beakers using the scalpels. 6. Watch until one of the blocks have gone completely clear. 7. Once one of the blocks have gone completely clear, stop the stop clock and take out the three blocks of agar and place on the tissue, and wipe off the excess sulphuric acid from the blocks of agar to prevent further diffusion with the two other blocks which have not been fully diffused to fully diffuse 8. Cut the blocks in diagonal, through the middle and using a ruler, measure how much of it has turned clear on each side. 9. Record the data for time taken, and the depth of the clear part on the table. Results Block number 1 2. 3 Block dimensions/mm 20x20x20 20x20x10 20x20x5 Predicted order of clearing 3 2 1 Actual order of clearing 3 2 1 Time taken for clearing 8mn56. 29s Depth of clear part on block/mm 3 4 5 Surface area/mmi 2400 1600 1200 Volume/mmi 8000 4000 2000 Surface are to volume ratio O:O. 3 O:O. 4 O:O. 6 Conclusion My prediction as to which block will go clear first was correct, being the smaller block, as its surface area to volume ratio was the greatest out of all three, even though there was not much difference between the three values. This is because the third block has a greater surface area for the sulphuric acid to diffuse into the agar, causing the diffusion rate to be greater. The blocks have become clear through diffusion caused by neutralization between the sulphuric acid and the agar, which is an alkaline. Evaluation Quite a few things did not go as planned in this evaluation, but I have come up with ideas on how to improve them if we do an experiment like this again. Firstly, the jelly size may not be accurate from cutting it, and when it has been stirred, bits of it may have chipped off causing a change in its surface area. Next time, to avoid this, we could measure the block of agar more accurately when cutting it, and also be more careful when stirring the agar and stir softer so that no bits may get chipped off. Not only that, but the time we place the three blocks of agar into the sulphuric acid may be different, as well as the time we started the stop clock. Next time, we may possibly find a different method of putting in and taking out the agar so that it remains a fair test, and so that there are less mistakes in the test, which may be reduced by having one person per block of agar and beaker, as well as another person for the stop clock and placing it in and taking it out all at the same time as well as starting and stopping the stop clock. Another complication may have come from the amount of sulphuric acid in each beaker, which may not have been equal. This problem may be reduced by measuring the sulphuric more carefully, maybe with a measuring cylinder before then placing it into the beaker, instead of measuring it into the beaker straight away. Our measurements of the depth of the clear layer of the blocks of agar jelly may have been incorrect as well, and to prevent this, we could possibly use a microscope next time and use a graticule to measure the depth that the jelly has diffused to obtain a more accurate result. The last problem I noticed while doing the experiment was when we were blotting the sulphuric acid off the agar. I found that there may have been some sulphuric acid left on the agar after we have blotted it, which may have caused further diffusion and adjusting our result. This is caused from not blotting off enough sulphuric acid off the agar. Next time, we could carefully blot all the sulphuric acid, and use one piece of tissue for each block of agar so that there is no sulphuric acid on the tissue before blotting each block of agar.

Aspects of microeconomics and macroeconomics

Aspects of microeconomics and macroeconomics On this assignment will be looking into different aspect of microeconomics and macroeconomics, will be taken into consideration the definition and concept of the whole question as follow below. Part 1 (Micro section) Q1 To help understands by defining Demand that is the quantity of a good which consumers want, and are prepared and able to pay for. In this case the demand of organic food and drink has fallen sharply, and the main influence for fallen on demand for those products are: price; income; the price of substitute goods; the price of complements; taste; demographic factors; advertising and expectations. Price is one of the most important factors and it shift demand curve when it rises, the effect is shown by a movement along the demand curve, because consumers are likely to substitute cheaper alternative goods. http://upload.wikimedia.org/wikibooks/en/c/c1/DemandCurveMovementExample2.png The demand curve is downward-sloping, showing that as a price falls, demand rises, and vice versa. In this graphic, a reduction of price from P2 to P1 causes a rise in demand from Q2 to Q1. Usually, the more people earn, the more they will spend. The demand for most goods increase as income rises, and these goods are known as normal goods. And organic food and drink are normal goods, because the demand falls as consumers income falls, and vice versa. Demand can change sometimes, because of the expectation of price changes in the future. For example, post-Christmas sales may push customers to postpone spending until January. In an article entitled Food Price, Ellis makes the point that (à ¢Ã¢â€š ¬Ã‚ ¦) The proportion of shoppers buying organic food dropped by five per cent in the previous year. In July 2009, research carried out by marketing consultancy Cohn and Wolfe also reported that British shoppers are turning their backs on premium foods, organic produce and Fair-trade goods. According to the Cohn and Wolfe report, 69 per cent of shoppers say they intend to stick to their belt-tightening shopping practices even after the downturn ends (). www.bbc.co.uk/food/food_matters/foodprices.shtml#what_about_the_recession. Q2 The production possibility frontier illustrates the problems of scarcity and choice and the opportunity cost of resources allocation decisions. The opportunity cost of something is what you give up to get it. To understand the idea the economy, which produce two goods as manufacturing and financial services, with all resources employed, producing more financial services can only be achieved by some sacrifice on manufacturing services. It can be illustrated on diagram below shown. B A 0 The frontier shows all the maximum possible outputs given the economys existing quantity of resources. It can have any combination of goods along the line. Point A shows a society which is failing to use all of its resources to the full, either through inefficiency or unemployment. Point B is currently unachievable, but can be achieved throw economic growth. The shape of the curve is bowed outwards to the origin, is based on the notion of that society progressively allocates more resources to the production of a particular good, the opportunity cost of doing so will increase. In other words the curve is bold because the more input the less is the output. For example, UK economy is based on services because the government decide not to invest on manufacturing and thought the easiest way to make money is by providing financial services especially banks and shoppings only 13% of UK GDP comes from manufacturing. Now the services have been beaten by the recession, many banks are facing financial problems, because they use to lend money to people who were at lower income. Many of these people cannot repay their mortgage because they lost their jobs and they are haven their home been repossessed, it is causing serious problems on economy; records can be seen on graphic below. http://news.bbc.co.uk/1/hi/business/7789844.stm Q5 It is important to be aware of the differences between theoretical models: a perfectly competitive firm; monopolistic competitive; oligopoly and a monopoly. But here only two will be taking into account. Perfectly Competitive Monopoly Very many small suppliers One supplier only Homogeneous goods; Suppliers products are a perfect substitute for one another One type of product only; no close substitutes available One market price Price set by one firm. Possibly price discrimination Demand curve of individual firm is horizontal. Demand curve of firm and industry is downward-sloping Perfect information Imperfect Information No barrier to entry in the long run Barriers to entry Clearly the assumptions essential perfect competitive extremely are not likely to apply in the real world; there is no market which obeys all the conditions. On the other hand, there are some that come close. The stock markets and foreign exchange are examples. Also complying with regulations the market is costly, as is training and equipment needed to operate in such a sophisticated, highly computerised market. As you can see, the conditions are not obeyed perfectly, but it may be that the markets are near enough the formal definition that displays the main characteristics of a theoretical perfectly competitive firm. The monopolist produces less, and charges more, than the perfectly competitive firm. He makes supernatural profits, which would be competed away in a perfectly competitive market in the long run. He may also be technically inefficient, operating at above minimum average cost. The monopolist equates marginal cost and marginal revenue. The perfectly competitive market equates marginal cost and average revenue. In perfect competition, each firm produces at the point where P=MC. PART 2 (Macro section) Q1 The economy is in recession because production is below its potential capacity, the term recession mean lack of money supplier. To respond this crisis the government is intervene through fiscal and monetary policy to increase aggregate demand, and the way for doing it is by supporting bank balance sheet; cutting in direct taxation(VAT -2.5); quantitative easing (bank of England) and employment level. Fiscal policy is basically about government taxation and expenditure. To help in this crisis the government has reduce the consumption tax VAT -2.5 to 15% to stimulate investment expenditure, but there was a big criticism about this idea, because reducing VAT did not cause long term impact in the economy, would cause more impact if they invest the  £12 billion building an public infrastructure to increase an aggregate demand. Monetary policy the bank of England is an independent monetary policy institution there a committee people appointed by government to make decision about interest rate, monetary policy is focus in regulating the money supplier in the economy through interest rate it has a big impact on aggregate demand. The bank of England has reduced its interest rate to 0.5% to boost the UK economy and start lending money to business and individuals. As the economy beginning to grown some others part of the economy will be automatically adjust, for example an increase on employment. Some companys worker has agreed to have a pay cut on their salaries to reduce people being redundant (BA Line). Automatic adjust as the economy beginning to grow the employment rate will decline http://news.bbc.co.uk/1/hi/business/7832714.stm According to Kyosaki, Robert, Rich dad poor dad 2, E, (2008), few people have anticipated the financial problems we face today were created more than 60 years ago by politicians and lawmakers predecessors. Q3 In the post-war period government have adopted four central objectives of macroeconomic policy: low inflation; full employment; rising economic growth and balance of payments. But full employment is too hard to archive especially there is a trend for national income to experience cycle of growth and contraction, i.e. boom and recession. These cause severe social problems as failing level of economic activity throws people out of work and causes business to fail. The term unemployment means those of working age who are without work, but who are available for work at current wage rates. Unemployment could still exist because of many causes mentioned below: Cyclical unemployment, this occurs due to a deficiency of demand, often refers to the fact that in such circumstances it is possible that prices will fall. Frictional unemployment, refer those people who are unemployed and jobs available rarely match perfectly, leading to an inevitable degree of unemployment. Technological unemployment, can occur when industry is growing and moving towards more efficient capital intensive methods of operation. Seasonal unemployment, relates to fluctuations in demand for labour directly related to cycles in demand for final product. Tourism and leisure industries are the best examples, these can contribute to regional problems as they are strong in particular areas. Some of the remedies that government can use to reduce the level of unemployment are: direct increase in government spending on public infrastructure; encouragement of business investment by offering grants and loans; encouragement of exports; subsidise firms in financial trouble, guarantee jobs for workers facing redundancy and to restrict imports of competing foreign goods and also using specific measures to get people back into work like new deal programme and so on. The relation between unemployment and inflation can be explained with Philips curve, by Professor AW Philips in the 1862-1958. Philips observed that the rate of change in money wages was inversely related to the level of unemployment. Rising money wages were identified as a source of inflation and the inflation appeared to be inversely related to the level of unemployment. http://welkerswikinomics.com/students/wp-content/uploads/2008/08/fig21-300269.jpg Q4 The globalization and the environment are linked, because for expansion of economic, environmental damage are produced that are essential to the process of globalization. Mander argue that Globalization is a human creation that aims to remove impediments, such as environmental laws that restrict companies access to resources and markets, environmental damage is therefore an intrinsic part of the globalization system. www.gale.cengage.com/pdf/samples/toc32870.pd The intention of having a globalized world and to lower trade barriers, protecting free trade and my environment, thus bringing the economic development in poor countries, so that people have access to information, improving their health and liability to environmental protection. The process helps to globalize the ideas run free from one country to another, increasing the availability of knowledge and other opinions, helping the development among the nations. But for many environmentalists and anti-globalists Globalization will lead to environmental disaster and will gradually lead to the destruction of the environment, because the vision of globalization and produced without precedents to environmental deterioration. Speth points out that Since the end of World War II economic expansion has produced enormous environmental damage and global economic development can be expected to bring about even more dire economic consequences. www.gale.cengage.com/pdf/samples/toc32870.pd He believes that with globalization the few developed countries are benefiting because there was an opening up huge markets for them, since many of these poor countries produce more effective products and efficient, doing so will be multinationals are setting up in places, boosting investment foreign direct investment, and generating many jobs open to residents, e.g. Asian Tigers of South Korea, Taiwan, Hong Kong and Singapore demonstrated the great benefits of globalization and free trade. www.futureharvest.org/ news / globalization_pir. In the other hand, there is a great inequality and between rich and poor countries. Aislin It has been argued that poor countries are often exploited and pushed into the world trade forums. For example, it is evident when the rich nations are allowed to pay huge subsidies to their farmers, which leaves LDN is a disadvantage industrial Workers. http://www.abcnews.go.com/sections/politics/dailynews/TheNote_March5.html Q5 If imports goods are too high it may be possible to reduce demand for them in the economy by imposing tariffs to raise the price of imports goods to prevent unfair competition in the home market. Also to avoid buying product from the market were workers have been exploited to export their product cheap. This policy is likely to be met by retaliation from overseas countries, which will reduce exports putting the current account back into deficit. In addition, imposition of tariffs does not reduce expenditure if demand for imports is relatively inelastic, government policy favouring domestic suppliers may mean higher than necessary taxes to pay for the higher necessary purchase cost, and restrictions generally encourage smuggling and black market For example, a poor country that in main revenue comes from the tax on trade, if withdraw the tax trade its revenue will reduce significantly also the amount of investment on public infrastructure will be reduce, consequently many import goods may come into the market in a low price, causing the domestic goods serious problems on market as well as increase unemployment. The balance of payment also will be affected; because of lack of exportation it may cause government to borrow some money to balance the balance of payment.

The Career of Lance Armstrong :: essays research papers

It’s a year since we bid farewell to a legend the ultimate cycling champion. He is a cyclist who has overcome all the challenges life has thrown his way and still continues to do so. Lance Armstrong known around the world for what he has achieved and overcome. Armstrong’s name has become synonymous with the unique yellow jersey of the punishing Tour De France. It is the life and story of a true legend. Armstrong is just a man like any one of us a man who had dreams as a child of becoming someone famous his dream was to win the tour de France at twenty –four he was well on his way to becoming a top cyclist then in October 1996 he was diagnosed with stage four testicular cancer it seemed as if this time he was fighting a losing battle however Armstrong has possessed an epic sense of determination he dismissed the medical odds on that day his life changed forever this was a battle that would demand all hi energy this was a battle he was determined not to lose this determination helped him to develop into the world class cyclist he became he himself acknowledged the irony that â€Å"cancer was the best thing that ever happened to me’’ Just sixteen months after been discharged from hospital he entered the Tour De France the most grueling of all human endurance tests and won it in the fastest ever time who would have believed that a man on the verge of death would rise to become a champion of this stature Armstrong will admit even though he has won seven tour De France tittles his closet and most intense race was his one against cancer this race had the steepest hills, the sharpest turns and the slipperiest roads. It was a race in which he came face to face with death, and he won. Sunday the 24th July 2005 brought an end to his illustrious career. It was the day he wrapped up his 7th Tour De France victory, the day he retired and a day that will be remembered for many years to come. Since overcoming cancer he became the name that dominates the sport of cycling. Lance Armstrong revitalized cycling and the Tour de France, he turned cycling into a world-class sport and the Tour de France into a mega media event. I am sure that we were all in awe of this amazing mans courage and his wonderful achievements beyond all odds.

Greek Architecture Essay -- essays research papers fc

Greek Architecture: History and Mechanics   Ã‚  Ã‚  Ã‚  Ã‚  Throughout history, there have been several significant architectural movements. The last, and perhaps most enduring movement is that of Classic Greece. Although for centuries, the architecture of ancient Greece has been admired, mimicked, and replicated, its beginnings are somewhat surprising to one unfamiliar with the history of the region. It is important to understand the history and mechanics of Classic Greek architecture in order to fully appreciate its form, function, and beauty. â€Å"Ancient Greek architects strove for the precision and excellence of workmanship that are the hallmarks of Greek art in general. The formulas they invented as early as the sixth century B.C. have influenced the architecture of the past two millennia† (metmuseum.org).   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"The first inhabitants of the Greek peninsula, who are believed to be Neolithic, built very primitive and basic structures. The houses were mainly built with a circular, oval, apsidal, or rectangular shape†¦ They used mud bricks and stones in the mud with reeds or brush to help build the house. Most of the houses had one room, there were very rarely two† (thinkquest.org). These simple homes are the primary foundation for the Grecian style of architecture. Though Neolithic in nature, the first Architects laid the basic foundations for all architecture to follow in Greece and the rest of the world. The shapes of these early homes carry through all the way from the Ionic to the Corinthian order.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"The next group of settlers were the Minoan architects. Their towns were mostly residential with little or no temples and public places. Unlike earlier people, their houses were private and had many rooms†¦to separate rooms, they would use only pillars† (thinkquest.org). These new people introduced several different aspects to the foundation of Grecian architecture, namely, the openness of the houses and rooms. It is this culture, which is mostly accredited with introducing the mechanics of the ancient Grecian forms of architecture. â€Å"The first advanced culture in Greece, and indeed in all of Europe, was created by a people referred to today as the Minoans. Their civilization flourished from about 2200 to 1450 B.C. on Crete, the large island located about one hundred miles southeast of the Gree... ...on. It is important to understand the history and mechanics of Greek architecture in order to fully appreciate it. The ancient Greeks were very well known for their beautiful temples. They were able to devise several different ways to create beautiful buildings and implement those designs. The ancient Greeks set the architectural foundations for the rest of the world with their three orders. The three styles, or orders, are the Doric, Ionic, and Corinthian. The three distinctive styles are referred to as orders because they display proportionate, ordered, and coordinated parts. The Doric, Ionic, and Corinthian orders serve a functional purpose, as well as lend so much beauty to structures. â€Å"All the world’s culture culminated in Greece, and Greece in Athens, all Athens in its Acropolis, all the Acropolis in the Parthenon† (Nardo, 61).

Psychology – Biological Explanation of Eating Disorders

Psychology Essay The biological approach suggests that AN is due a physical cause, suggesting it could be due to something within the body or brain; such as hypothalamus dysfunction or an imbalance of neurotransmitters. The hypothalamus dysfunction theory would suggest that animals have a â€Å"set weight† which is correct for their body, if this weight should increase or decrease then the body should make adjustments to regulate food intake to their â€Å"set weight†.The hypothalamus is thought to have quite a lot of control over our eating behaviour, the lateral hypothalamus (LH) is considered to be the feeding switch that makes an individual begin to feed whereas the ventromedial hypothalamus (VMH) is the satiety switch that makes an individual stop feeding. Garfinkel and Gardner (1982) suggested that a disturbed hypothalamus may be the cause of AN, they proposed that any disturbance could lead to either the LH or VMH to be constantly activated.In order to explain AN it is most likely that when the LH is damaged and that the individual never receives a signal (feeling hungry) to begin feeding, if the VMH were damaged then the individual would receive a constant signal to eat so they would never stop feeding. This supports the idea that AN might have a biological explanation, specifically brain dysfunction.Anand and Brobeck conducted an experiment involving the rats, they found that if the LH was damaged it could lead to aphagia (this is a failure to eat when hungry), this provides support for the idea that damage to the hypothalamus can lead to reduced eating which is support for the biological approach of AN. However, there are some concerns with this as the test was conducted with the use of animals so it’s hard to generalise the findings to humans.This is because humans and animals are biologically different so it’s hard to know if humans would respond in the same way if their LH was damaged. Additional research has shown us th at when the VMH in rats is stimulated that it stops feeding, which again supports the suggestion that possible over activation of the VMH could result in reduced feeding. This research would also support the biological explanation of AN as if an individual has damage to their hypothalamus then it could result in reduced feeding which would then result in dramatic weight loss, as seen in sufferers of AN.However, this theory is reductionist as it suggests that the only explanation of AN is a biological reason, and it ignores other factors; like things such as stress or sexual abuse which can both lead to AN. Another biological explanation of AN would be that there is an imbalance of serotonin, which is usually associated with depression and anxiety; as disturbed levels of serotonin have been found in AN sufferers.It is also likely that eating disorders arise due to high levels of anxiety which is linked with high levels of serotonin in the body. Bailer et al (1970) compared serotonin activity in recovering anorexia suffers and healthy controls. They found significantly higher activity in the women that were recovering from anorexia, the highest levels found in those women with the highest anxiety levels. This also provides support for AN having a biological cause, in this case an imbalance of neurotransmitters.However, it’s difficult to establish cause and effect in Bailer’s research, this is because the women studied were already recovering from an eating disorder and so it’s impossible to know whether the imbalance of serotonin was the cause of the women’s AN or whether the AN causes an imbalance of serotonin, so it’s hard to know whether or not there is a biological cause of AN with these findings. In addition to this the research is also gender biased, in this case it’s alpha biased as only women were used in this study but it’s generalising the study to men as well. Bailer’s research also raises the de bate of determinism vs. ree will. The biological approach is deterministic so if an individual has an imbalance of serotonin they will then develop an eating disorder, however this is ignoring our free will as an individual that exercises regularly will over their eating; this is noted in individuals who suffer from anxiety but don’t develop AN. Finally there is the evolutionary approach which suggests that all our behaviours are adaptive, which means that the reason we do certain things is to help us survive in a certain way; according to this theory AN is a behaviour which helps them survive.The evolutionary approach focuses on our ancestors, when weight loss and eating disorders weren’t a consideration and any weight loss would be a lack of food rather than a desire for â€Å"thinness†. Usually when an individual begins to love weight physiological mechanisms activate in order to conserve energy and increase desires for food, however it would not have been ad aptive for our ancestors to feel hunger as there may not have been much food available to them, so instead it would be adaptive to â€Å"switch off† the desire so that they could then find food; in order to help our survival.Therefore many characteristics of AN can be considered adaptive to enable our ancestors to move to areas where there was more food rather than being preoccupied by looking for food in their current location. However, this theory doesn’t explain the differences of AN between genders, as girls are more affected by AN than boys; so if the behaviour was adapted then both men and women would be equally effected by this as both genders would have had to search for more food in other areas.An alternative approach to explaining how AN would come from the behaviour approach, which suggests AN is the result of learning rather than a biological explanation. This approach suggests that individuals suffer from AN because of reinforcement, so they have witnessed slim people (who become their role models) being rewarded for their behaviour so they imitate their behaviour in expectation of the same reward.

The Stigma Of Hiv Aids Health And Social Care Essay

This reappraisal aims to show the contested nature of biomedical and laic constructs of wellness and mending underpinning Human Immunodeficiency Virus/ Acquired Immunodeficiency Syndrome ( HIV/AIDS ) and its stigma. Due to the wideness of the topic the reappraisal will merely be restricted to HIV/AIDS and stigma in relation to the interactions between Peoples Populating with HIV/AIDS ( PLWHA ) and the wellness structures that supply them with bar and intervention services. Literature and stuffs from different published beginnings would be reviewed and analysed, followed by a critical comparative analysis of the key contested constructs of wellness as applied to HIV/AIDS and stigma, eventually reasoning with an interface of the two theoretical accounts. HIV/AIDS is one of the challenges to human life and self-respect. It affects all degrees of society and has a monolithic impact on planetary economic and societal development, ( Rowden, 2009 ) . Surveies have been conducted on its impact on human life and how it could be controlled. This reappraisal was conducted by researching literature from a assortment of beginnings for published articles on HIV/AIDS and its stigma. Literature from research covering a period of 8 old ages from 2002-2010 was extracted from Assia, PubMed, Sage, British Medical Journal, Cochrane and Absco-host, and reviewed for the survey, aims, methodological analysis and cardinal findings. Relevant books, diaries, paperss and studies from administrations such as UNAIDS, and the World Bank were besides reviewed. Both qualitative and quantitative information was used to show the information. Despite confronting a batch of unfavorable judgment on its top-down attack, the biomedical theoretical account remains the dominant construct in wellness and unwellness. Its credibleness lies on its scientific methods and expert cognition used to name or understand unwellness and intervention. This theoretical account views the organic structure as a machine composed of different parts working together for it to work. If one portion is non working decently, the purpose is to happen what is incorrect with it through diagnosing and repair it by ordering medical specialty, ( Taylor & A ; Hawley 2010:12 ) . Focus is hence restricted to the physical unwellness of an person ‘s organic structure and the scientific apprehension of disease, doing the attack to a great extent based on pharmacological medicine. While pharmacological medicine is good in the intervention and bar of HIV/AIDS, it is criticised for advancing the privilege of the biomedical theoretical account, farther heighten ing undermining of alternate attacks to wellness and healing. The biomedical attack may be inappropriate to some communities and create feelings of weakness and exposure hence impacting the success of the intercession. ( Global Health Watch, 2008, Farmer, 1999 ) . Lay constructs of wellness and unwellness are diverse and complex than those of the medical theoretical account. They focus on people ‘s experiences of wellness and unwellness in relation to their overall life experiences and are embedded within local societal and cultural constructions. Unlike in the biomedical attack, autochthonal attacks seek to mend the whole individual by associating the unwellness with the individual ‘s societal and economic background, ( Taylor, 2003 ) . However critics of this theoretical account argue that ballad constructs are hard to grounds and research hence they remain marginalised and barely recognised as legitimate cognition, ( Taylor & A ; Hawley, 2010:13 ) . On the contrary, Taylor, ( 2003 ) argues that ballad position is important cognition for public wellness as it identifies roots of unwellnesss for possible long term bar and intervention for the larger population as comparison to separately focussed intercessions. Influence of power systems such as the laterality of the medical theoretical account hinder advancement on bars and intervention of diseases such as HIV/AIDS and stigma as they govern relationships between wellness constructions and laic people. Goffman, ( 1990 ) , and Parker and Aggleton, ( 2003 ) , ‘s theories of stigma in assisting us to understand how stigma is constructed and its influence in peoples ‘ lives view stigma and favoritism as functional systems which maintain boundaries between those in power and those without. Through such power, societal inequalities are developed taking to creative activity of societal norms. These formulate stigma by regulating interactions between people and reenforce power constructions that serve to keep control of the powerless, ( Farmer, 2005 ) . Both theories have been widely used in HIV related stigma to foreground how bias, negative attitudes, maltreatment and ill-treatment directed towards PLWHA have hindered the advancement of bar and intervention. Research high spots that stigma and favoritism in wellness attention scenes deducing from societal power instabilities contribute a great trade in maintaining people off from accessing HIV/AIDS intervention and attention. Patients felt greatly affected by wellness workers experiencing uncomfortable with them and handling them in an inferior mode. In Tanzania, some discriminatory and stigmatised patterns such as dish the dirting about patients ‘ HIV ‘s position, disregard, verbal maltreatment, proving and unwraping HIV ‘s position without consent were noted, ( D.C Synergy, 2005 ) . Similarly in India, wellness workers were unwraping patients ‘ HIV position to their households without patients ‘ consent, ( Mahedra et, Al, 2007 ) . Harassment, avoiding and isolation of HIV-positive patients and proving without reding are common characteristics of stigmatization in most surveies. Some wellness workers wore protective vesture even if there was no physical con tact during interactions. Fear of being identified as infected with HIV besides influenced people to protract proving for HIV and merely accessed services when their unwellness was at an advanced phase, ( Bond and Aggleton, 2002 ; Kinsler et Al, 2007 ; Varga et Al 2006 ; Kalichman and Simbayi, 2003 ) . In Zambia, HIV-positive wellness workers were concealing their Hiv position from their co-workers in fright of being stigmatised, ( Dieleman et al, 2007 ) . While most of the literature on HIV/AIDS and entree to wellness services is negative, there is grounds of the value of supportive and de-stigmatising HIV services in some parts of the Earth. Brazil has been hailed as a theoretical account by PLWHA. They reported supportive inclusive structural systems that create healthy environments that promote active engagement of different groups in society and the authorities, ( Caltado, 2008 ) . In South Africa where most people believe in traditional healing, Aids Activism has made a positive significance in HIV/AIDS bar and intervention by interpreting and interceding the biomedical attack within local ideological models which are easy understood and acted on by the locals, ( Colvin, Robins, 2010 ) . Literature reveals that collaboration between ballad positions and biomedical attack is indispensable for successful control of HIV/AIDS and stigma. There is no remedy for AIDS but Anti-retrovirals ( ARVs ) can protract life by take downing degrees of HIV in the organic structure hence detaining the procedure between HIV and AIDS, ( Robin, 2009 ) . Although ARVs are now readily available in most states, Numberss of freshly infected people are lifting. Harmonizing to the World Bank, 60 million people are populating with HIV/AIDS worldwide. Access to intervention has increased dramatically but for every 100 people on intervention, 250 become freshly infected, ( World Bank, 2010 ) . As such, force per unit area is now lifting on the effectivity of merely trusting on the biomedical attack for intervention and attention of HIV/AIDS. While ballad positions are considered effectual, this can non be confirmed as true with HIV/AIDS attention. In South Africa, despite people to a great extent trusting on traditional healing attacks, HIV prevalence continued to lift. Significance towards effectual control of the epidemic has been noted with the addition in handiness of ARV ‘s, ( Colvin, 2009 ) . In the UNAIDS Report On The Global AIDS Epidemic 2010, in 7 states, five of them in Eastern Europe and Central Asia, HIV incidences increased by more than 25 % between 2001 and 2009. Sub Saharan Africa, although still staying the most extremely affected by the epidemic, figures either stabilised or showed marks of diminution owing to positive behavior due to increased services that are embedded in local civilization. The study affirms that stigma and favoritism, deficiency of entree to services and bad Torahs can do the epidemic worse, ( UNAIDS, 2010 ) . Due to the challenges presented by HIV/AIDS to planetary public wellness, Baum. ( 2008:241 ) calls for corporate engagement of all sectors in the battle against this deathly disease. She asserts that community degree mobilization where there is partnership between ballad people and constructions is the effectual manner of battling HIV/AIDS and stigma. This is farther supported by Farmer, ( 1999:90 ) , who does non excuse the laterality of the biomedical position in wellness and healing. He believes that ballad people have a important function in the procedure of wellness betterments and accents on the importance understanding ballad people ‘s experiences as indispensable cognition for successful intercessions. He holds that wellness attention services should be accessible to PLWHA without fright of being stigmatised. Educating wellness attention professionals about the impact of stigma on patients and policies that encourage inclusion of PLWHA in determinations that affect thei r lives are some of the cardinal factors of efficaciously undertaking the epidemic. Parker and Aggleton, ( 2003 ) besides claim corporate engagement between ballad people and wellness constructions as cardinal to successful anti-stigma services. Relationships between wellness constructions and PLWHA could besides be improved by prosecuting ballad people through protagonism. The Greater Involvement of PLWHA, ( GIPA ) rule emphasises the demand for engagement of PLWHA at all degrees in battling HIV/AIDS because they understand their state of affairs better. Therefore their voices could be heard good if their demands were presented by people in the same state of affairs, ( UNAIDS, 2007 ) . In the Zambia survey, professionals populating with HIV/AIDS are in a better place to recommend for people accessing services. Baum, ( 2008:550 ) affirms that advocacy affecting public wellness practicians is an effectual manner of act uponing structural barriers in public wellness. Literature has highlighted the contested nature of constructs of wellness and mending underpinning entree to services supplying intervention and bar of HIV/AIDS and its stigma. The biomedical attack conceptualises wellness and unwellness through scientific discipline and expertness with focal point on the person. Lay concepts position wellness and healing as embedded within local societal and cultural constructions and hence seek to turn to public wellness for a wider population. Literature suggests that neither attack in isolation is effectual in bar and attention for HIV/AIDS. Arguments have centred on the importance of coaction of the theoretical accounts. Therefore there is demand for intercession programmes to develop holistic attacks that are underpinned by the two theoretical accounts but it is besides of import to understanding each of the constructs in its ain right.

Terrorism A Common Definition Of Terrorism - 972 Words

Most of the countries around the world call the terrorism a common enemy, but there is not a common definition of terrorism. There is not any significant unified goal and objective among the states against them, but they have their collective and shared goals. They are against the peace, stability, and development and they want to kill, destroy and spread fear. They misuse and misinterprets any faith in their favor and they try to mix terrorism with the religious ideology. And they support each other globally for these shared goals, but we should ask ourselves, what do we do to defend ourselves and defeat terrorism? Climate change, the proliferation of weapon of mass destruction (WMD) and terrorism is widely debated as a threat around the world. These three issues might be the top three issues in front of us in the 21st century. However, the WMD proliferation and climate change are considered as major issues since the 20th century, but still there are some states, who want to produce nuclear weapons and pollute the environment and they struggle globally to justify their interest against the interest of the world community and humanity. There is no doubt that some states sponsor terrorists, but I have not heard of any government, who publicly backs or defend terrorists.
