Supply and Demand and Budget Line

TASK 1 Consider the following equation: MRSXY < PX/PY where MRS = marginal rate of substitution x and y are two goods P = price < = is less than {draw:frame} The graph above shown us the indifference curve budget line diagram which explaining the equation MRSXY < P X / PY. There are two ways to measure the consumer preferences or what the consumer wants. The first one is by trying to put a ‘value’ on the satisfaction a consumer obtains from consuming a ‘unit’ of a good. Consumers are assumed to be able measure utility in terms of a ‘util’. However, we cannot find the total utility by using this method. So we can use another way which is by ranking the product. We can say that the consumer is preferred good Y compared to good X. the indifference curve is a curve that shows consumption bundles that give the consumer the same level of satisfaction. So this means that the consumer is satisfied at any point if the indifference curves above. The slope of the indifference curves are downward sloping. For example, the consumer will satisfy when he buys 3 good X and 4 good Y. The meaning of the term budget constraint is what the consumer can afford to buy. The income of the consumer will determine how much he can buy in the market. So, the budget line in the graph above is showing how much good X and Y that the consumer affords to buy. If the slope of the budget line is higher, this means that the consumer afford to buy good X compare to good Y. While if the slope of the budget line is lower, the consumer afford to buy good Y compare to good X. From the graph, we can see that the consumer is not maximizing the satisfaction. This is because the indifference curves are inside the budget line and it intersect at two points which are a and b. At point b, the slope of the indifference curve (MRSxy ) is less than the slope of the budget line (Px/Py). While, at point a, the slope of the indifference curve (MRSxy ) is greater than the slope of the budget line (Px/Py). So the consumer does not maximizing the satisfaction for both point a and b. In order to maximize the satisfaction, the slope of the indifference curve must equal to the slope of the budget line. So at point b, the consumer should reduce the consumption of good X and increase the consumption of good Y until both slope of indifference curve and budget line will become the same. By switching spending away from good X towards good Y, the consumer will be able to reach a higher indifference curve. {draw:frame} From the graph, we can see that the indifference curve has shift and meet the budget line at the point c. at this point, the slope of the indifference curve and the budget line are the same. So the equation will change to [MRSXY = PX / PY]. At point c, the consumer satisfaction is at the highest place. The consumer choice is the product which been sold in the market. While, the individual demand for a product is the demand of a consumer on that product. The demand on a product will be higher if there are only small choices in the market. People tend to demand more for the product as they cannot find other product. TASK 2 *Definition of Price Elasticity of Demand (PEoD*) The price elasticity of demand is the measure of how responsive is the quantity demanded to a change in price. There are many types of elasticity in demand which will stand for different types of product in the market. In order to differentiate between them we need to state the definition and the ratio of the elasticity. Relatively Elastic Demand The relatively elastic demand is a demand relationship in which the percentage change in quantity demanded is large in absolute value than the percentage change in price. In other words the percentage change in quantity demanded is larger than the percentage change in price. {draw:frame} The ratio for the relatively elastic demand is 1< PEoD < Infinity Relatively Inelastic Demand The relatively inelastic demand is a demand that responds, somewhat, but not a great deal to change in price. In other words, the change in percentage change in price is larger than the percentage change in quantity demanded. {draw:frame} The ratio for the relatively inelastic demand is 0 < PEoD < 1 Unit Elastic Demand The unit elastic demand is a demand relationship in which the percentage change in quantity demanded is the same as the percentage in change of the price. {draw:frame} The ratio for the unit elastic demand is PEoD = 1 Perfectly Elastic Demand The perfectly elastic demand is a demand in which the quantity demanded drops to zero at the slightest in price. In other words, the quantity demanded will become zero if the seller increases the price of the product. While they will never reduce the price as it will reduce their normal profit. {draw:frame} The ratio for the perfectly elastic demand is PEoD = Infinity Perfectly Inelastic Demand The perfectly inelastic demand is a demand in which quantity demanded does not respond at all to the change in price. {draw:frame} The ratio for the perfectly inelastic demand is PEoD = 0 Calculating the Price Elasticity of Demand The formula to determine the price elasticity of demand is: PEoD = (% Change in Quantity Demanded)*/(*% Change in Price) Price (OLD) =9 Price (NEW) =10 Q Demand (OLD) =150 Q Demand (NEW) =110 Calculating the Percentage Change in Quantity Demanded [QDemand(NEW) – QDemand(OLD)] / QDemand(OLD) [110 – 150] / 150 = (-40/150) = -0. 2667 Calculating the Percentage Change in Price [Price(NEW) – Price(OLD)] / Price(OLD)] [10 – 9] / 9 = (1/9) = 0. 1111 PEoD = (% Change in Quantity Demanded)/(% Change in Price) PEoD = (-0. 2667)/(0. 1111) = -2. 4005 TASK 3 The product that I choose is tobacco. Both of the elasticity of demand and supply of tobacco is relatively inelastic. This is because the product will has an inelastic demand if the item is habit forming. As tobacco is a habit forming, it is relatively inelastic in demand. So if there is increase in price, the quantity demanded will not respond too much. While, the supply of the tobacco is relatively inelastic is because of the time period. As the tobacco is the agriculture product, it will take some times to grow it and get the product. So the producer cannot increase the quantity of supply although there are many demands for the tobacco. TASK 4 {draw:frame} The graph above has shown a market of tobacco with the relatively inelastic demand and supply curves. As we can see, the total surplus has reduced since the implementation of the tax. The benefit received by buyers in a market is measured by consumer surplus. The consumer surplus is the amount buyers are willingly to pay for the good minus the amount they actually pay for it. So the consumer surplus before the tax are (a + b + c). However, after the implementation of tax on the tobacco, the consumer surplus is only a. This means that the consumer needs to pay more after the implementation of tax. P in the graph stands for the price of tobacco before the tax. While, P*B* is the price that buyers need to pay after the tax has been implemented. The benefit received by sellers in a market is measured by producer surplus. The producer surplus is the amount of sellers received for the good minus their cost. So the producer surplus before the implementation of tax is (d + e + f). But, the producer surplus change after the implementation of tax, which became only f*. * This means that the seller received less profit after the tax implemented. **P*S in the graph is the price that seller received after the implementation of the tax. So this means that, the consumers and producers have to bear the tax burden after the tax has been implemented. Tax burden is the amount of tax suffered by individuals or organization. The tax burden for the consumer and seller may vary depends on the elasticity of the demand an d supply curves. Although the consumer and sellers seems to be burden by the tax, there is one party that gains benefit from it. It is the government because it has gain revenue from the tax. The tax revenue is the (b + d) in the graph above. From the revenue, the government can use it for other investment. However, the tax has also brought another disadvantage which is the deadweight loss. The deadweight loss is the reduction in total surplus that results from a tax. The deadweight loss in the graph is (c + e). The size of deadweight loss also depends on the elasticity of the demand and supply curves. If both of the curves become more elastic, then the size of the deadweight loss will become smaller. So in the conclusion the tax has given benefit to the government but brought disadvantages to the consumer and producer. REFERENCE LIST Mankiw, N. G. (2008). Ten Principles of Economics. In J. W.

Drug Abuse within University Students in Ottawa Essay

The term drug abuse refers to any use of any drug for something else a part from its planned medical or psychiatric purpose. The use of such drugs may involve using prescription drugs for wrong purposes or using illicit drugs. For instance, research has shown that in Ottawa many university students take drugs not for the intended medical use but mainly to get high. Most students from Ottawa who abuse the drugs in most cases obtain the drugs illegally from unlawful sources. This puts their lives in danger as they engage in dangerous methods of use of drugs that swerve from the accepted medical practice or scientific knowledge and they take drugs for reasons that they are not meant for (Weibe, 1994). The Ottawa integrated drugs and addictions strategy community network have been holding several meetings in an attempt to identify the issues related to prevention, treatment, harm reduction and enforcement among the Ottawa university students engaging in substance abuse. In this regard, the community network is therefore preparing to consult the public on related issues. The consultation from the public by the community can only be done conveniently through research, studies and surveys. Thesis statement The abuse of drugs such as cocaine, marijuana, heroin and other illicit drugs has been on the rise among university students in Ottawa. Several attempts have been made by different groups including the Ottawa integrated drugs and addictions strategy community network to come up with preventive measures and health promotion strategies but the drug abuse by these students is still on the rise. The current studies however have raised more concern on the female student abusers since in the recent past, less attention has been given to them and this as a result has exposed them to excessive abuse of these drugs and therefore facing severe suffering as compared to their male counterparts who are abusing the same drugs (Single, Robson, Xie & Rehm, 1996). Research questions Some of the questions prepared for the phenomenological research included; do the university students in Ottawa use or abuse drugs? If they do abuse the drugs then what are the most commonly abused substances among the students? What percentage of female student’s abuse drugs in relation to the percentage of the male students who abuse the same drugs? Is there any difference in the level of consumption between the genders? What effects do the student abusers suffer from the consumption of these drugs? Do the drug abusers suffer the same effects? Interviewing For our interview we are not going to inquire about the name of the student being interviewed but we are rather going to refer to the students as student one up to student six respectively. Our interview questions are going to be based on the research questions mentioned above. This being a phenomenological research whatever is reported in this paper is going to be exactly as it appeared to the observer during the research (Rocheleau, 1995). Student one Researcher: as one of the university students in Ottawa, do you think university students in Ottawa are using drugs or are they abusing the drugs? Student one: the of drugs use by university students in Ottawa is growing at a very high rate and therefore fits to be referred to as drug abuse since in most case are used for purposes other than the intended ones, for instance most students take drugs to get high. Researcher: what are the most commonly abused drugs by the university students within Ottawa? Student one: the most commonly used drugs are cocaine, marijuana and at times heroin and many others. Researcher: how would you approximate the number of female students abusing drugs relative to the number of male students in percentage? Student one: it is a fact that the number of male students abusing the drugs is higher than that of the female students abusing drugs and it can be approximated to about 50% of the female population and 70% of the male population. Researcher: what effects do the drug abusers suffer after consuming the drugs? Student one: most students suffer depressive disorders and mood disorders. Student two Researcher: as one of the university students in Ottawa, do you think university students in Ottawa are using drugs or are they abusing the drugs? Student two: actually the drug consumption by university students in Ottawa only fits to be described as drug abuse. Researcher: Why do you think the description best fits ‘abuse’? Student two: the use of drugs has become too much and also the drugs used by students are addictive and not meant improve health. Researcher: which drugs do the university students in Ottawa used most? Student two: the drugs commonly used are cocaine and marijuana but others like heroin and alcohol are also used. Researcher: which group is most affected by the addiction habits, is it the male students or the female students? Student two: the male students seem to be more affected than the female students since they seem to consume in large numbers compared to the female students. Researcher: what effects do they suffer after consuming the drugs? Student two: the effects mostly suffered include mood disorders and depressive disorders. Researcher: do both the female and the male students suffer the same effects? Student two: other than the already mentioned disorders, female students do suffer a lot of stigma and confrontation from their family members and friends unlike male students who do not experience the same (Pauline, 1997). Student three Researcher: as one of the university students in Ottawa, do you think university students in Ottawa are using drugs or are they abusing the drugs? Student three: the drugs that are consumed and as they are consumed by university students within Ottawa are definitely abuse. Researcher: which drugs do the university students in Ottawa use most? Student three: the drugs commonly used are cocaine, marijuana, heroin and alcohol. Researcher: how would you approximate the number of female students abusing drugs relative to the number of male students in percentage? Student three: the number of female students using the drugs is usually lower than that of the male students abusing the drugs so according to my approximation it is 48% for female and 65% for male. Researcher: what are the effects of drug abuse by the students? Student three: students who abuse the drugs in most cases seem depressed and out of mood and usually fail to perform normally. Researcher: which group do you think is most affected by the drugs? Student three: the female students seem to be more affected since they tend to suffer more long term effects than male students. Student four Researcher: as one of the university students in Ottawa, do you think university students in Ottawa are using drugs or are they abusing the drugs? Student four: the drugs as consumed by the students are more abuse that use. Researcher: why do you say so? Student four: the rate, the purpose and the frequency of drug consumption by university students cannot be termed as usage. Researcher: which drugs do the university students in Ottawa use most? Student four: the drugs commonly consumed are marijuana, cocaine, alcohol, heroin among others. Researcher: how would you approximate the number of female students abusing drugs relative to the number of male students in percentage? Student four: the percentage of male students consuming drugs is usually higher than that of the female students consuming drugs. Researcher: what are the effects of drug abuse by the students? Student four: the effects of drugs includes stigma which is mostly suffered by female students, others effects are mood disorders and depression. Student five Researcher: as one of the university students in Ottawa, do you think university students in Ottawa are using drugs or are they abusing the drugs? Student five: the rate and quantity at which drugs are consumed is said to be abused. Researcher: which drugs do the university students in Ottawa use most? Student five: the drugs commonly used include cocaine and alcohol. Researcher: how would you approximate the number of female students abusing drugs relative to the number of male students in percentage? Student five: the number of female students consuming the drugs when compared to the male students is 45% to 65 %. Researcher: what are the effects of drug abuse by the students? Student five: the effects are hangover, failing to perform properly, dizziness and depression. Researcher: which group do you think is most affected by the drugs? Student five: those who abuse the drugs suffer the same effects. Student six Researcher: as one of the university students in Ottawa, do you think university students in Ottawa are using drugs or are they abusing the drugs? Student six: the students do abuse the drugs. Researcher: which drugs do the university students in Ottawa use most? Student six: mostly they consume cocaine and at times alcohol, marijuana, heroin and many others. Researcher: how would you approximate the number of female students abusing drugs relative to the number of male students in percentage? Student six: the percentage for male students abusing drugs is higher than those of female abusing drugs. Researcher: what are the effects of drug abuse by the students? Student six: drug abuse causes depression, malfunctioning, mood disorders and many others. Purpose of the study The main objective of the study on drug abuse by university students in Ottawa was to find out if the students do use or abuse the drugs, to establish the motivations behind the consumption of these drugs, to clarify the rate of drug abuse by university students in Ottawa, to identify the drugs mainly abused by university students in Ottawa, to verify the relationship between the female students consumption and male students consumption, to identify how the abuse of these drugs affect the lives of the students, to identify some of the measures that can be taken to prevent drug abuse by the students and to treat the already affected students (Pauline, 1997). Delimitations of the study The main advantage enjoyed during the study was that it was easy to find and interview different students on the issue of drug abuse among them since the study was conducted during school session when all students were in their respective learning institutions therefore it involved less cost around looking for students to interview. In addition, enough private rooms for interviews were provided where students felt free to share their ideas on the topic of discussion. Limitations Even though the students were available, most of them proved so unreliable. This is because most of the students were not ready to be interviewed. Those who were ready for the interview however tended to give inadequate information since most of them did not want to disclose full information regarding their drug use status as they considered it something private and therefore wanted to preserve it. In addition, most students who were given capsules to treat their drug abuse related disorders were not willing to take them, which resulted, to a lot of wastage. Consequently, it was not easy to get urine samples for test from drug abusers since most of them could not allow it. (El-Guebaly & Hodgins,1992). Research strategies Having a topic of study, the phenomenological research strategy involved, first developing the topic. â€Å"In case, it is a drug abuse among university students in Ottawa, What effects does the use illicit drugs such as cocaine, marijuana and many others have on the health of students? † needed to be asked before proceeding with the research. The next step involved finding the background information on drug abuse by university students in Ottawa. This was done by looking for the key words of the topic from encyclopedias with the subject. From the encyclopedia, several articles were read which set the context for the research. Additional background information was found from textbooks and other reserved materials, which involved research, conducted on the same topic by different researchers in different years. It also involved finding out for how long this has been going on and what has been done to prevent it (Ogborne, Braun & Schmidt, 1996). The research further involved finding books and articles to find out what other researchers who conducted their study on the same topic found out. It was from here that a comparison was made to find out if the statistics on the drug abuse by university students in Ottawa has changed. The past studies were of great significance since different ideas on what should be done to prevent the practice were suggested without having to repeat the measures that had been implemented and which did not work. In concluding the research, different sources of information were evaluated and cited in relation to how comprehensive the information got from them were. Role of the researcher The main role of the researcher in this study was to interview different students to be able to verify their opinions and perception of the use of illicit drugs within or outside their learning institutions. The researcher was also to find out the major motivations behind the students’ drug abuse behavior and the effects they suffer after consuming the drugs. In addition, the researcher was to administer some drug abuse disorder related capsules to find out how effective they could be in reducing drug samples in blood. Furthermore, the researcher was to carry out some random tests on some of the drug abusers to find out the drug that is most commonly abused by university students in Ottawa (Weibe, 1994). Strategies for ensuring trustworthiness During the study, it was not easy to convince the students to reveal information regarding their drug abuse behaviors. This was because the students were more concerned about preserving their privacy, which they were not willing to make known to the institution authorities, their parents and even friends. It was therefore upon the researchers to explore different strategies to convince the students that whatever they were going to discuss was to remain a secret between the student and the interviewer. This was done by ensuring that the involved only two people i. e. the researcher and the student in a private room where no any other party could steal the topic of discussion (Christensen, Jacobson, 1997). Literature review The phenomenological research on drug abuse by university students in Ottawa found out that the drugs possibly abused by these students are mainly prescription drugs. Such drugs are usually opiate based for pain relief, tranquilizers, stimulants and amphetamines. Others also include sedatives and barbiturates. The study however found out that the most seriously abused drugs by the students of Ottawa University are cocaine and marijuana. Most students who abuse drugs such as the barbiturates were found to do so with the intention of getting rid of anxiety and sleep disorders. On the other hand, the abusers of tranquillizers consume them with an intention of reducing stress and panic attacks. Studies on drug abuse by students since 1970s has shown that male students consume more drugs than their female counterparts. The frequency of drug usage was also found to be high in males than in females. For example, a study conducted on Ottawa University students on drug abuse confirmed that about 74% of male students compared to 53% of female students consumed more than one to two standard drinks in the previous year (Corbett, 1994). Very recent studies on drug abuse among university students however showed that there was a smaller gender difference in levels of drug consumption. A recent survey of Ottawa university students showed that 83. 3% of female students and 84. 9% of male students had abused drugs in the past one year. Most Ottawa university male and female students are assumed to consume drugs moderately. Nevertheless, a clear gender difference is confirmed from self-reported by the students of excessive drug consumption. The excessive consumption especially alcohol consumption is defined by four or more drinks by female students on a single occasion and five or more drinks by male students on a single occasion. The rate for harmful consumption for female students is however higher than that of male students. Almost a half of the total female students (42%) who had engaged in drug abuse were reported to have had harmful abuse as compared to 46. 3% of all the male students who had abused drug that year reported to have had harmful abuse (Ogborne, Braun & Schmidt 1996). Harmful consumption of drugs as was identified included those who felt in the wrong after consuming the drug, those who could not remember anything after taking the drug, those who suffered drug abuse related injuries and those whom after consumption of the drugs suggested reduction in drug abuse among students (El-Guebaly, 1990). Other than those who suffered harmful abuse, there are those who were found to be dependent abusers. Dependent abusers involved approximately 28. 6% of female students and 30. 5% of male students. It was noted that the dependent abusers could not stop using the drugs, could not perform expected activities after the consumption of drugs or needed some morning consumption of the drugs. The table below shows the percentage of university students by sex who were reported past year for harmful and dependent drinking. Sex Harmful drinking Dependent drinking Female 42% 28. 6% Male 46. 3% 30. 5% On further survey, 56 percent of all the female abusers were found to be taking at least five drinks on a single occasion in the course of the year. On the other hand, 26. 1% were found to be taking at least eight drinks on one occasion during the same period. In addition to the above surveys, a research conducted indicated that 30. 4% of male students were reported to have taken alcohol beyond the low risk guidelines for alcohol consumption as compared to 15. 2% of the female students (Ogborne, Smart& Rush 1998). According to the research, in a situation where the harm got from drug abuse is as a result of substance abuse, there occurs very small gender difference quoted by male and female students. For instance a study conducted in 2004 confirmed that 6. 9% of female students and 9. 1% of male students reported that there occurred at least harm in their lives during the past year as a result of their drug consumption and 30. 4% of female and 30. 7% of male students reported harm as a result of another person’s consumption(Corbett, 1994) In 1994 a survey recent reports showed an increasing drug abuse for illicit drugs such as cocaine, heroin and others by male and female students. Generally, male students were found to be on the front line when it comes to reporting the use of illicit drugs as compared to their female counterparts. Nevertheless, the most recent reports point to an increasing self-reports by both female and male students in the use of cannabis although a significant gender difference remains. On alcohol and other drugs abuse, 10% of male students and 5% of female students were reported to be abusers of cannabis while a same study conducted in 2004 indicated an increment to 18% for male students and 10% for female students. In addition, the same study in the 2004 indicated that 7. 35% of female students and 14. 1% of male students were abusers of cocaine. The study conducted in Ottawa University provided enough evidence that the difference in gender in relation to illicit substance use is getting smaller. Alarm on this situation has attracted international attention especially from Australia, united sates and other European Union countries. In the year 2004, 15. 8% of female students and 18. 1% male students reported harms from their own cannabis consumption. Research has shown that approximately 25% to about 33% of all students using injection drugs in Ottawa University are female students. This has been identified as a major factor for HIV infection in female students. It has been noted that of the entire positive tests of HIV in women from the year 1985 to 2002, between 33% and 48% have been as a result of injection drug use. Reports from the study revealed that there is consumption of the ketom plant leaves by university students in Ottawa as a drug because the leaves of ketom plants contain hallucinogens, which are as intoxicating as marijuana. The increased abuse of drugs in university colleges is blamed on the difficulties in enforcing laws in such institutions, which speeds up the spread of such drugs. (Corbett, 1994). A further research showed that many drug users do suffer mood disorders. For instance among those abusing cocaine, the most commonly detected disorders are depressive disorders. The analysis revealed that the association between mood disorders and drug abuse among the abusers is usually very complicated. Most drug abusers do build up depression that comes as a result of physical and psychological endurance connected with the use of drugs. The study showed that most students who suffered mood disorders after abusing cocaine became drug dependent after making attempts of self-medication. Initially it was not easy to handle the conditions of students who were suffering from both mood disorders and drug abuse but it became possible after a research revealed that a treatment on mood disorders alone could have a positive effect on drug abuse (Boyd, Millard & Webster 1985). A research that was conducted on students involved urine test whereby unsystematic weekly examinations indicated a significant high use of cocaine as compared to marijuana by different students. Most of the students who tested positive for drug abuse however, were found to have come from families with a history of substance abuse, which in most situations reached, back to several generations. All students from such families had started abusing the drugs long before enrolling in the institution. All students who participated in the study and who happened to be drug abusers were given packets of capsules which they were to take two times each day during the four week study. For most of the students, the capsules included lithium prescription that had shown its effectiveness in treating adult bipolar patients. Bipolar disorder in most students was found to have been caused by substance abuse disorder including the use of marijuana, alcohol, cocaine and other multiple drugs. During the study, a number of students were also treated as outpatients and given weekly therapy sessions in addition. In the course of the study, blood vessels of lithium were tested at least twice every week to ensure that the participants were taking the capsules given to them. Samples of urine were also taken on a similar basis to scrutinize the use of drug (Christensen & . Jacobson, 1997). The percentage of the students taking the lithium capsules, the drug positive samples changed from 38% to approximately 8% indicating a significant reduction. Four random tests were conducted during the study and the urine samples that were tested revealed the students self reports. They were definitely a noteworthy reduction in the use of drug. In addition to reduction in drug use, the students receiving lithium capsules progressed in the symptoms of bipolar disorder. The improvement was mainly noted in their ability to function properly in school activities as compared to how they could function before the study. Chronically drug dependent students who were suffering from primary and secondary depression were recognized in the course of the study and treated. Most students who experienced a drop in depressive symptoms and those who noted improvements confessed that they had noted a reduction in their crave and use of drugs mainly cocaine and marijuana. The research that was conducted indicated that there has been almost forty years of trying to prevent drug abuse among university students in Ottawa. This has been done by conducting youth counseling especially to those who have developed drug addiction. In addition to youth counseling a treatment centre for youth who are suffering from drug abuse related disorders have been opened to help treat the youth. In an evaluation of the best measures to put forward in trying to find treatment to substance abuse in Canada, a study showed that female students do suffer a lot of stigma in connection with their substance abuse problem as compared to the male students. In addition, the research has established that the female students do suffer much confrontation from their families and friends and most negative consequences in treatment center (El-Guebaly, 1990). The female students do suffer the negative consequences in treatment centers as a result of problems from family members, neglect by friends, lack of finances to cater for the treatment bill and other unfavorable effects related to the well-being of females. It has been demonstrated in different researches that advertising of drugs has a very strong influence on the way university students in Ottawa perceive some of these drugs and can therefore be a source of motivators to these students to engage in their consumption. Furthermore, female students as compared to male students experience sexual abuse and physical abuse, which in most cases have a strong relationship with substance abuse. Research has demonstrated that female students who had at one time in their lives suffered sexual assault in most cases do use or misuse drugs at early ages and in most cases, they use them in large quantities (El-Guebaly & Hodgins, 1992). For According to the research conducted, the effect of abusing drugs and especially the illicit drugs such as cocaine and marijuana have been found to diverge among female students and also between female and male students depending on the drugs that are on hand for use. The effects of the drugs however do depend on the type of drug consumed, how regular the abuser use the drug, the amount of drug consumed and the general health condition of the person consuming the drug (Smart, 1983). Example a review on the effect between male and female students established that female students are affected very much differently from male students with rapture. The analysis of the study showed that female students with rapture unlike male students do experience more severe sensitive changes and difficulties in making decision. In addition, the female students suffer more long lasting effects such as mood swings, depression, paranoia and anxiety than their male counterparts who engage in the consumption of similar drugs. Consequently, the death rate from substance abuse among university students in Ottawa seems to be high for female students as compared to that of the male students. Findings From the study on the causes of drug abuse by university students in Ottawa its has been found that there is inadequate education and prevention measures that look into the needs of different individuals and especially university students over their life span. It has been pointed out that there is an immense distinction between what is said and what is done as far as prevention of drug abuse among university students in Ottawa is concerned. According to the planners, prevention measures should be long term and lasting, however most prevention measures put across are always short term due to poor funding. In addition to this, there is lack of treatment centers for people suffering from drug related disorders thus causing long waiting lists for university students (El-Guebaly, 1990). The study has also revealed that advertisements of different drugs and lack of implementation of policies regarding drug abuse in the universities in Ottawa are some of the major motivators behind the students’ drug abusing behavior. The drugs found to be more accessible as a result and therefore most commonly abused by the students were the cocaine and marijuana. The findings from the research have also indicated that the female students are the major sufferers from drug abuse and addiction even though the male students seem to consume drugs at higher rate and more frequently than the female students. The death rate from drug abuse of female students has also been found to high as compared to that of male students. Conclusion Despite the fact that drug abuse among university students in Ottawa is still high, research has proved that most of the students involved in the practice are willing to drop the idea and promote their health status when appropriate measures are put in place. It is therefore upon the authorities concerned to take necessary actions to ensure that students are provided with enough information and resources to help them overcome the drug addiction (Ogborne, Smart $ Rush 1998). Significance of the study The study conducted on Ottawa university students has proved to be of great significance since several suggestions on how this problem can be solved have been suggested. The study was also of significance since different students were given an opportunity to express their feelings as far as drug abuse among university students is concerned and from that, it was realized that most students are willing and are ready to abandon the practice. In addition, most students were able to receive different tests on their blood and urine samples to verify the extent of drug level in their blood. Finally, most students were given capsules, which proved to be very effective in treating, and reducing drug abuse related disorders in their blood. Lessons learned From the studies and researches conducted it was clear that until recently very little attention was paid to female abusing drugs as compared to the attention given to male abusers both within the society and within the learning institutions. This is because female’s substance abuse has never been as high as that of male up to the recent past. Nevertheless, we are currently seeing some matching in the levels of drug consumption among female and males. The studies have also revealed that in making efforts to promote drug abuse prevention measures and health of the drug addicts in learning institutions, professionals, addiction system planners and public policy makers have not given any attention to motivations for use of drugs by students and the speeding up consequences of use of drugs by female students in colleges (Boyd & Webster 1985). Future direction From the lessons learnt from the study it was recommended that instead of exploring a system, that involves drug abuse prevention, programs for health promotion that includes males and females, the planners and the programmers should attend to differing needs of different students in relation to their gender, and other problems related to drug abuse. The high rates of heavy drug abuse by female students raised a lot of concern and recommendations such as low risk drinking guidelines for female students were made which required every female student involved in drug abuse to take at most three drinks in a single occasion or less than three in other circumstances depending on the type of drug being used. A further recommendation suggested that male students should limit their drinking to a maximum of fourteen drinks per week and the female students should limit their drinking to a maximum of nine drinks per week.

Prevention of Calcium Carbonate Precipitation in Synthetic Formation Waters

A new graduated table inhibitor for bar of Ca carbonate precipitation in man-made formation Waterss Abstraction In this probe, a new repressive chemical composing was developed. The made inhibitor is based on the aqueous solutions of oxiethilidendiphosphone acid, hydrochloric acid, ammonium chloride, polyethylene polyamine-N-methylphosphonic acid and isopropyl intoxicant to forestall the precipitation of Ca carbonate in a long clip operation of the well. The laboratory surveies of new inhibitor showed that the developed inhibitor has a greater suppression efficaciousness and continuance of desorption in comparing with the tried inhibitor SNPH-5312, which is widely used in the Fieldss in Russia to forestall the precipitation of Ca carbonate. The efficiency and corrosion aggressivity of new developed inhibitor were evaluated in three different man-made formation Waterss, which contained assorted ion concentrations and were disposed for precipitation of Ca carbonate. Introduction Huge sums of H2O are injected into the reservoir to keep the reservoir force per unit area at the needed degree, whereby, salt deposition occurs as a consequence of the H2O combination [ 1 ] . As the depletion of the oil field and its transportation to the late phase of development with increasing high H2O cut Wellss, scaling job is aggravated. Besides, there is the demand for backdown residuary oil, necessitating the usage of modern engineerings to better oil recovery, including physical and chemical exposure, which besides stimulates the deposition of salts. The chief grounds of deposition of salts are altering of thermobaric conditions in the procedure of production and the mutual exclusiveness of injected and formation Waterss [ 2 ] . Inorganic salts deposition on the interior surface of oilfield equipment takes topographic point in the procedure of field development of production of moire oil. Salt precipitation occurs in all operation methods of Wellss, but the most negative effects of scaling occur during oil production by electric submergible pumps ( ESPs ) [ 3 ] . Intense deposition of Ca carbonate on impellers ESP is due to the flow temperature addition of produced fluids, which is caused by the heat emanation of runing the submergible motor. Along with salt deposition in Wellss, intense salt precipitation is observed in the wellspring, oil grapevine assemblage, metering devices and installations for the readying of oil and besides in reservoir force per unit area care systems [ 4 ] . The procedure of precipitation of Ca carbonate occurs in three phases. In the first measure, ions of Ca combine with carbonate ions to organize the molecule. Following, molecules combine in microcrystals that serve as crystallisation centres for the reminder of the solution. Crystal aggregates grow and precipitate or attached to the walls of equipment at certain sizes [ 5, 6 ] . Calcium carbonate is found in the signifier of solid white crystals. Factors act uponing the formation of carbonate sedimentations include that formation H2O must be supersaturated with Ca, carbonate or hydrogen carbonate ions [ 7 ] . All control engineering of grading is divided into bar and remotion of scaling. The most effectual method is chemical method of bar by utilizing scale inhibitors. Basic technologies of inhibitor injection are divided as follows: reagent bringing into the wellbore and into the formation. Dose into the well is carried out by agencies of batcher dosing into the ring, into a given point along the capillary and the periodic injection into the ring through collectors. Dose into formation is done through squashing scale inhibitor, injection via injection Wellss ( in force per unit area care system ) , add-on of inhibitor by proppant during fracturing ( ScaleProp ) and injection of the inhibitor with the fracturing fluid during fracturing ( ScaleFrac ) [ 8, 9 ] . The intent of this work is increasing of operational efficiency of bring forthing Wellss by bar of formation of Ca carbonate in the downhole equipment, utilizing the developed inhibiting composing. Methods In the conducted research lab experiments for the readying of chemical solutions was used distilled H2O, in connexion with necessity to extinguish the influence on the belongingss of the composing and the consequences of experiments of ion finding, which were contained in different fresh H2O in assorted concentrations and ratios of their common concentrations. In the readying of look intoing composing harmonizing to the needed volume of the composing and concentrations of constituents, were weighed deliberate sum of H2O and reagents. Medical panpipes and high preciseness research lab balances were used for the exact values aˆâ€ ¹aˆâ€ ¹of the reagents multitudes. Scale inhibitor should be to the full compatible with formation H2O without the precipitation formation while salvaging their belongingss [ 10 ] . For the analysis, man-made solution, the ionic composing of which is near to the composing of formation H2O, is prepared. Inhibitory belongingss mostly depend on the content of Ca in the formation Waterss. Therefore, the compatibility standards can be that if in the readying of the inhibitor solutions in the H2O with a certain content of Ca2+, turbidness is non observed within 24 hours, the inhibitor at a given concentration is considered compatible with the given H2O. The prepared graduated table inhibitor should be more effectual and stable. The effectivity of the inhibitor is evaluated by its consequence on formation H2O or man-made theoretical account of H2O. Using theoretical accounts provides high truth measurings [ 11 ] . Determination of an inhibitor ‘s effectivity is made by appraisal of mass alteration of precipitation, which is formed in mineralized H2O in the presence of inhibitor with regard to H2O with no inhibitor [ 12 ] . Calculation of the protective consequence of an inhibitor is carried out harmonizing to the equation: E % =? 100( 1 ) Where Tocopherol is the scale inhibitor efficiency, m0and m are the multitudes of salt precipitate in the H2O with inhibitor and without inhibitor in gm, severally. The new graduated table inhibitor must hold the low corrosiveness. Corrosiveness of the developed composing is evaluated through the mass decrease of mention samples after their submergence in the inhibitor solution. Corrosion aggressivity of reagents was evaluated by hydrometric method – the weight loss of the samples. The corrosion rate of samples ( denseness of steel samples is 7821 kg.m-3) was calculated from the equation: Voltdegree Celsiuss=( 2 ) Where Vdegree Celsiussis the corrosion rate of the used sample in mm/year, m1and m2are the mass of the metal samples before and after the trial in gm, severally, S is the surface country of samples in m2, t is the trial clip in hr. Scale inhibitors should hold good adsorption-desorption features, heat opposition and minimum toxicity [ 13 ] . Evaluation of surface assimilation and desorption ability of suppressing composing is performed through research lab filtering of suppressing solutions for nucleus samples. Filtration surveies of developed inhibitor on nucleus samples are investigated by utilizing the setup FDES-645 ( Formation Damage Evaluation System ) . Reservoir temperature and force per unit area conditions are applied when utilizing this setup. Result and treatment The consequences of surveies to find the ionic composing of the man-made formation Waterss are shown in table 1. Table 1.

Sulin ‘s system is more descriptive of crude oil formation Waterss than are the other systems [ 14 ] . The entire mineralization of Waterss is located in the scope of 54 – 62 g/l. The theoretical accounts of H2O have the big concentration of hydrogen carbonate, carbonate and Ca ions, which are the chief factor of formation of Ca carbonate salt in the H2O because formation H2O must be supersaturated with thes e ions to precipitate this salt [ 15 ] . The developed composing of inhibitor is evaluated by finding the residuary content of scale inhibitors in samples of liquid. The concentration finding of P of inhibitor in the formation H2O is based on the reaction of phosphate ion with molybdate in acerb medium [ 16 ] . The optical density ( optical denseness ) of the obtained solutions is measured by a exposure tintometer at length ?=540 nanometer in cells with an absorbing bed thickness of 30 millimeter. The optical denseness should non transcend one. Control sample is taken as a standard solution. Each sample is measured on photoelectrocolorimeter two or three times, the arithmetic obtained values are used for the consequence of measuring. From the obtained informations, a standardization curve is plotted by utilizing on the horizontal axis the concentration of inhibitor in mg/l, and on the perpendicular axis the magnitude of its matching optical denseness. As shown in figure 1, the ensuing values of the optical denseness are cor related with the standardization graph and the concentration of inhibitor is found in the trial solution as a consequence of the experiments. Figure 1. The alteration in optical denseness of the solution, depending on the content of the inhibitor in H2O Evaluation of the effectiveness action of graduated table inhibitors by their ability to forestall the salt precipitation were carried out in the liquid solution of man-made formation Waterss. Trials were performed at a temperature of 25 ?C at the exposure clip of 24 hours. The consequences are presented in table 2. Table 2.

The inhibitor figure 1 gives the higher effectivity for bar of Ca carbonate precipitation in all formation Waterss. The difference be tween the inhibitors figure one and two is the alteration in mass fraction of inhibitor constituents. Inhibitor SNPH-5312 is an industrial inhibitor for bar of Ca carbonate formation, which is used in oil field. This inhibitor is based on the composite reagent of P. Table 2 illustrates that SNPH-5312 can protect Ca carbonate formation up to 87 % . Surveies have been conducted to find the compatibility of scale inhibitors with the formation Waterss. All inhibitors were compatible in three man-made formation Waterss, and the consequences showed all the above chemical composing can be prepared in the formation Waterss. The usage of chemical reagents for forestalling the deposition of salts in the Wellss is associated with the usage of chemically aggressive environments. A scale inhibitor is anticorrosion if there is no opposing on the surface of the sample and corrosion rate does non transcend 0.1 mm /year. The caustic activity of above graduated table inhibitors was carried out by hydrometric method by utilizing metal home bases through soaking for 72 hours at 25 ?C. Table 3.

Therefore, these reagents can be considered as reagents to forestall grading in Wellss. The initial concentrations of the reagents in suppressing composings are different, and so it is possible to compare the kineticss of the comparative concentrations of the solutions. The used nucleus samples had mean porousness of 20 % and permeableness of 70 mendeleviums. Figure 2 shows the consequences of finding of the comparative concentrations of the inhibitor reagents in the composings for the surface assimilation procedure at temperature of 120 ?C and force per unit area of 300 standard pressure. Laboratory surveies showed that the confining surface assimilation is achieved when pumping 14 pore volumes for suppressing composings figure 1 and 2, for complete surface assimilation of SNPH-5312, 15 pore volumes must be pumped. By comparing the comparative concentrations of reagents in figure 2 during surface assimilation, it can be concluded that the surface assimilation is faster when utilizing suppressing composings figure 1 and 2. Harmonizing figure 2, more unvarying surface as similation is observed in the composing figure 1. Figure 2. Concentration alterations of the inhibitor solution in the surface assimilation procedure in the nucleus Once the nucleus left for 24 hours to find the surface assimilation equilibrium, formation H2O is pumped into the nucleus to displace suppressing composing. Consequences of finding of the comparative concentrations of inhibitors are shown during the desorption procedure in figure 3. The optimum and recommended concentration of oxiethilidendiphosphone acid in the composing for field conditions, is 10-15 mg/l, it corresponds to the comparative concentration of 0.0001. Harmonizing to figure 2, utilizing the inhibitor SNPH-5312 can supply the needed remotion of the inhibitor, which is sufficient for effectual protection of precipitation of Ca carbonate, when pumping through the nucleus sample of 27 pore volumes of H2O. Effective protection against formation of Ca carbonate under similar conditions persists in pumping 37 pore volumes of H2O when utilizing the developed suppressing composing figure 1, and 32 pore volumes of H2O by composing figure 2. This demonstrates that the developed co mposing have 1.37 times greater continuance of desorption in comparing with the inhibitor SNPH-5312. ( a ) ( B ) Figure 3. Concentration changing of the inhibitor solution in the desorption procedure on the nucleus, ( a ) from 5 to 20 pore volumes, ( B ) from 20 to 40 Data analysis on remotion of considered repressive composings show that a important part of the free inhibitor ( non-adsorbed ) is passed in pumping the first two volumes of pore infinite. The efficiency of the developed composing is explained by the mechanism of influence on the stone acidic additives belonging to its composing. Decisions Inhibitory chemical composing was developed for the bar of deposition of Ca carbonate with an optimum ratio of constituent oxiethilidendiphosphone acid 3 % , ammonium chloride 4 % , polyethylene polyamine-N-methylphosphonic acid 4 % , hydrochloric acid 10 % , isopropyl alcohol 2 % , H2O – balance. The used graduated table inhibitor was evaluated in footings of influence on corrosion actions and it was in the scope of 0.040-0.053 mm/year when the maximal allowable rate is 0.1 mm/year. The new inhibitor was effectual for scale bar of Ca carbonate up to 92 % . The research lab surveies showed that the developed composings have about 1.37 times longer continuance in comparing with the desorption of the tried inhibitor SNPH-5312, which is widely used in the Fieldss for forestalling formation of Ca carbonate.

Paraphrasing#2 - Essay Example The readings are then to be taken using a multi-meter. Resistors in circuit one had all currents through the same because they were connected in series. In a series connection, voltage is divided among all the components. Resistors in circuit two had equal voltage through them because they were in a parallel connection. This is because current flowing through them is the same. In circuit three, R2 and R3 were in parallel hence equal voltage through them. The last circuit four had had R1 and R5 resistors in a series arrangement hence equal current through them. From the experiment’s results, the function generator produced square waves. It displayed in the form of waves as seen in the oscilloscope. The wave measured 3Vpp and 1.0 KHz and had the shape of a saw tooth. The experiment’s aim was to make a voltage divider in the multisim. The voltage divider was to equally divide circuit one into two parts. Circuits two and three were to be divided into three and four parts respectively. In the first circuit, currents I1 and I2 were equal. Vi1 and V2 were also equal since the connection was series. In circuit two, the voltage divider we designed divided the voltage of 12v three times and verified that by measuring with a multi-meter. In circuit three, we again verified that the voltage divider had divided the 12v. In circuit one, we determined the voltages Va, Vb, Vc Vac, and Vbc using readings from the multi-meter. The current I2 and source current Is3 were also determined. In circuit two, current through the 10ÃŽ © resistor was also determined. In the last circuit three, a nodal analysis was applied in the circuit. The objective was to examine the prototype board and use the multi-meters provided to measure the resistance, current, and DC current through the circuit. Using the oscilloscope, we were also to measure Ac voltage. Finally, we have to create voltage from the generator provided. Based on the experiment’s objectives, we

Case study - international marketing - Essay Example 2. For any emerging market, the best strategy often applied is the localization of products or services offered as because it makes the product line and the brand more acceptable to the customers. For the case of Disney, this strategy has proved to be winning in not only the mass markets of China, but in the Indian markets as well and as well as in many others. 3. The global market today comprises mostly of youth that the movie tends to attract, as well as the outstanding promotions adapted like karaoke style. Also releasing it in different local languages made the movie a block buster in the global market. Conclusively, the movie had all that is demanded from clear cut drama to top class music which made the packaging of the product (movie) a victorious release (Johnson, 2007). Whirlpool 1. Previously, the product strategies adapted by Whirlpool was mostly focused on the extension factor rather than the adaptation factor. Whirlpool has recently invested hundreds of millions of dolla rs to develop new extensions in their product-line. However with time and market saturation, Whirlpool realized that to have an effective product line according to local markets where the product had to be localized, adapting both the strategies is needful according to the market situations worldwide. In the near future the company shall be focusing more on adaptation strategy in maintaining its competency in the global markets rather than introducing extensions in its product line (Whirlpool Corporation, n.d.). Notably, the strategy adapted in case of China was called as ‘T4’ by Whirlpool. 2. The reasons for buyers to opt for Whirlpool products are mostly because people find it more time saving than manual work to use these appliances as well as it involves lesser effort and energy. Additionally, people today are going for these kinds of appliances as they reflect the status of customer in many markets. 3. Whirlpool emphasizing largely on market research has been able to design their product according to the preference of the consumer in their global markets. This was proved at the redesigning fact of washing machine in China and Brazil which includes different specifications. Besides this, Whirlpool correctly believes that the products have to be altered according to consumer preferences which could only be found by conducting primary market research and analyzing secondary research data. Whirlpool has used secondary data to analyze the fact that Brazilians will be able to pay for even their cheapest appliance owing to their monthly income. This lead Whirlpool to design another appliance which was according to the demographics of the market but then again, this wasn’t the consumers’ actual concern. Therefore, the new product included consumer specific features which were found through focus groups and primary research. Whirlpool conducts both ethnographic and anthropological research work at the initial stage of a product which hel ps in developing the product as per the need of customers and get aware of the opportunities in the given market (DesignCouncil, n.d.). 4. One important lesson that Whirlpool learned in the market of China and other is that the local market overview is as important as the international overview. Besides this, before venturing on with

State Coordinating Boards and accountability measures Essay

State Coordinating Boards and accountability measures - Essay Example In order to enhance competitiveness in the international marketplace, Governments are increasingly focusing on the need to improve the quality of human capital that is the product of higher educational institutions. Therefore, there is an accountability that is being demanded of these organizations, through the use of external evaluation and performance measures to assess the quality of the education that is being imparted and the effectiveness of policy outcomes. These moves are posing a threat to academic freedom, which gives an individual the right to â€Å"study and teach whatever he or she wants to without threat of sanction† [Tierney, 1998, pp 41], even if this course of study may be such that it does not contribute to maximizing economic returns for the public dollars that have been funneled into education. Educational institutions have traditionally functioned with autonomy because that makes them more â€Å"flexible and responsive, given their relative freedom from command and control by centralized Government†¦..[The result] is higher levels of organizational innovation and more variety within national systems of higher education† [Dee, Henkin and Chen, 2000, p 204]. However, increasing economic pressures leading to the corporatization of higher education are impinging upon the autonomy of educational institutions [Bok, 2003] and pose a serious threat to the achievement of true academic goals [Kirp, 2003]. The conflict between maintaining academic autonomy while simultaneously persevering policy accountability is an ongoing one, in which State Coordinating Boards are faced with the greatest difficulties in defining their role and achieving the right balance between autonomy and accountability.

Comparison of the Effectiveness of India and Chinas Politics and Research Paper

Comparison of the Effectiveness of India and Chinas Politics and Economics in the last decades - Research Paper Example This paper is one of the best examples of comparison of the effectiveness of Chinese and Indian economic policies during the last decades. The reasons behind better economic performance of China are considered. During the analyzed period, The Chinese demonstrated a remarkable ability to execute on its social and economic agenda with the concerted planning of the socialist government and leveraging the competencies and entrepreneurial capabilities of the Chinese masses. In India`s case the observation is that even as the middle classes have swelled, the large parts of India remain agricultural, and that there are issues surrounding the rise of cities versus the continued reliance in agriculture of a large majority of the Indian population. This in turn has implications for the ability of India to do well financially and to lift its masses out of poverty, as well as care for its social well-being China achieved better results than India, because of some fundamental differences in the defectiveness of their executions relative to their reform strategies, some differences in governmental structures and existing constraints, and differences in underlying cultural contexts and political contexts for pushing growth. There have been profound differences in investments in fundamental social services like education, with China being better able to educate its masses than India, resulting in long-term disparities in the ability of the nations to lift its masses out of poverty and improve their economic lot.

FAMILY LAW Essay Example | Topics and Well Written Essays - 2500 words - 2

FAMILY LAW - Essay Example The main setback identified in this area is due to the fact that the national criminal justice system does not consider domestic abuse or violence as criminal activities, and fails to provide adequate protection for women against such offences1. To compound the misery, there is considerable bureaucratic apathy among the enforcement authorities, such as the police, prosecutors and judges. These persons have been found to be unwilling to identify the causes of domestic violence. Therefore, the enforcement of laws against domestic violence has not been effective or constructive. Most law enforcing authorities do not view domestic violence as a serious criminal issue, and consider it to be a private problem. Their belief is that women have to deal with the problem of domestic violence and arrive at a solution to it by themselves. Most women believe that the criminal justice system acts as a barrier to their seeking the court’s intervention to eliminate violence. Several international bodies claimed that domestic violence is a violation of human rights. They also demanded that human rights must be made applicable to domestic violence. Human rights treaties have to develop effective instruments to address the problem of do mestic violence2. Activities such as physically hitting or slapping or a threat to cause harm to the victim or child of the victim, threatening to commit suicide or demeaning the victim verbally or physically, restricting the victim in visiting his or her friends or family member would constitute crimes of domestic violence3. Domestic violence is distinct from other types of assault. It should be dealt with separately with a separate dedicated mechanism for handling of cases; and there should be high levels of prosecutions and punishments. Only then will it be possible to eliminate domestic violence from the lives of women. The effects of domestic violence are much higher than that of physical assaults.

To what extent can agricultural biotechnology can hold the key to sustainable food security in Sub-Saharan Africa (SSA) - Essay Example This essay as well shows the prospective of public†private joint ventures and gives recommendations of policy courses along with ventures that can centre more research in biotechnology on the issues of the poor and lessen some of the alarms concerning the biotechnology influences. The Biological Diversity conference describes biotechnology as: "use of living systems and organisms to develop or make products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use". With this explanation, the definition of biotechnology covers various methods and tools that are common in production of food and agriculture. The Cartagena Protocol on Biosafety2 describes â€Å"modern biotechnology† more narrowly as the appliance of: b. Cells fusion further than the taxonomic family, which surmount recombination barricades or natural physiological reproductive and which are not methods used in assortment and conventional breeding. A narrow interpretation which simply considers the innovative DNA methods, molecular biology along with application of reproductive technology, the description entails several diverse technologies like manipulation along with transfer of genes, cloning and typing and cloning the DNA of animals and plants. Even though the media has covered technology extensively in the last few years, this technology that has an extensive history that dates as far back as 6000 B.C. Progress in technology and science have altered conventional biotechnology methods, like hybridization, mutagenesis and selective breeding, into current ones, like tissue culture and recombinant DNA methods. This makeover has presented an opportunity extra applications in many areas like health care, forestry, industrial processes, the environment, and many others. The existing

Foreseeability in law Coursework Example | Topics and Well Written Essays - 250 words

Foreseeability in law - Coursework Example There are numerous arguments claiming this requirement is unjust and that the defendant should be held responsible for the actual consequences of any careless conduct that results in injury, whether foreseeable or not. However, this broadens the scope of the tort considerably and would open up an endlessness of liability. Further, foreseeability ensures fairness for the defendant. Is would be unjust to hold a defendant liable for conduct which they could not have anticipated would result in injury. Being penalized for conduct which does not foreseeably cause injury would result in numerous frivolous claims. Accidents occur all of the time. While it would be fantastic for the injured party to always have recourse for legal action, it would not be fair to those defendants of whom are undeserving. There are some injuries no one could predict and no one but the forces of fate should be held responsible and certainly no one should be penalized. This may be unfortunate for the injured party, but the blame cannot always be laid at someone else's feet. Foreseeability ensures blame can only be laid at the feet of those who should have reasonably foreseen the consequences of their actions. This is fair. This is just. Taking away the requirement of forseeability would make the opposite true.

Law In Practice - University Level-3-CIVIL PROCEDURE Essay

Law In Practice - University Level-3-CIVIL PROCEDURE - Essay Example ct 2007, states that a solicitor cannot act for two or more clients where there is a conflict of interest between them or a significant risk of such a conflict arising. Conflict of interest would arise in case the firm is responsible for the case of both the parties that is Mr. Bragg or Mr. Johnson in relation to the RAT or any related matter. A check should therefore be carried out and assured that the firm is not representing Mr. Johnson either in this case or any other case as a matter of fact.1 But from the file it looks that there is no conflict of interest and a note to this extent will be made in the file. Section 24 A (2) of the Limitation Act lays down the limitation period for claims for damages for personal injuries arising out of negligence, nuisance or breach of duty. The limitation period is the later of: In this case the accident took place on 12th April 2007 and based on Section 11(4) Chapter 58 of the Limitation Act 1980 (as amended by the Latent damage Act 1986) the time for calculation of the limitation period began to run from the date the accident took place. The limitation period for this accident is 12th April 20102. Thus Mr.Bragg can be given an assurance that he still is within the limitation period to make the claim. After the file is studied properly it is clear that there is very little time on hand for the limitation period 3 within which the procedure has to be started. But there is no evidence in the file with regard to the fact that any application is made to the court4 for extension of the limitation period so that the documents and other evidences supporting the case can be accumulated. Also time is required to carry out the pre-action protocols with regard to the personal injury claim. In the event the claim is barred by the statute and refusal on the part of the court for extension of the limitation period then under such circumstances the client can sue the firm for negligence on its part. The driver Mr. B. Johnson was

Logon Identification and Password System Essay Example for Free

Logon Identification and Password System Essay This is with reference to the management’s approval to upgrade our Information Technology (IT) system or the structure of our computer processor in order to expedite the hospital’s operational processing. As the Information System Director of this hospital, I highly recommend the introduction and/or implementation of a Logon Identification and Password System or what we may technically refer to as the LIPS. The LIPS, which will be applied and carried out in our central processing unit, will require that once a user enters into the system, the computer unit prompts or requires for a user’s name and password. The said details should have been previously registered in the system so that it will be recognized because if not, the user will be unable to use any computer unit of the hospital such as our desktop computers and laptops or notebooks. Once this recommendation is considered, the system will work in such a way that it will speed up the computer processing which concerns all the possible information of each patient particularly his or her medical records in the hospital. Additionally, the LIPS aims to lessen the workload of concerned hospital personnel because the processor or mainframe will simplify the works which need to be done such as the computer processing of patients’ admission, laboratory results, billings and other related matters. Most importantly, the rationale behind this LIPS recommendation is the hospital’s objective to adapt and keep abreast with the technological demands and necessities of today’s modern setting. In doing so, we will be able to provide our public with an exceptional hospital service. For your information and approval.

Critical Regionalism Was First Introduced Cultural Studies Essay

Critical Regionalism Was First Introduced Cultural Studies Essay The idea of critical regionalism has been heard in architecture society. Vitruvius discussed regional variations in architecture in his ten books, and the Romantics propounded picturesque regionalism during the nineteenth and early twentieth centuries. However, regionalism seems to against the theory of modernism and postmodernism, both of which were thought to have failed to address the human condition in their extreme stances towards historicism. Thus from the question, how to become modern and to return to sources? by Alexander Tzonis and Liane Lefaivre hypothesize critical regionalism as the solution. The term was originally introduced by Tzonis and Lefaivre in their article The Grid and the Pathway, where critical regionalism was presented as the third and latest type of regionalism in Greece, succeeding the English picturesque of nationalist regionalism and the Neoclassical historicist regionalism. Here, modern architecture is thought to be remote and massive, destroying the hu manistic character in architectural term which would be stated by a new form of regionalism. Frampton follows the lead of Tzonis and Lefaivre in exploring the theory critical regionalism. In the article Towards a Critical Regionalism, Frampton defines critical regionalism as an architecture of resistance, seeking to mediate the impact of universal civilization with elements derived indirectly from the peculiarities of a particular place, Thus aiming to reflect and serve the limited constituencies in which it was grounded. It is a resistance in the sense that it is a reaction against universal standards, culture homogenization and placeless modernism, but at the same time critical in its outlook; self-evaluating such that is is confrontational with not only the world but also to itself. According to Tzonis and Lefaivre, this self-reflective function is executed through the method of defamiliarization, in contrast to the romantic regionalism of familiarization, which employed nostalgic picturesque elements from a foregone era. This process entails selecting regional elements and incorporating them in a way that may appear distant, as if it were the sense of place in a strange sense of displacement, seeking to disrupt the sentimental link between the building and the place, and thus in this sense a reaction agaist the romantic sentimentality of pictureresque follies. Postmodernism, as its name suggests, aspired to succeed modernism whose ideals and norms were seen as responsible for the numerous failures that characterized most reconstruction and urban renewal projects realized since World War II. Having pledged to bring architecture out of a state of stagnation and disrepute due to reductive, technocratic and bureaucratic dogmas of modernism as well as its indifference, if not hostility towards history and culture, postmodernism buildings, apart from their superficial features, were qualitatively not much different from their predecessors. With few exceptions, museum buildings, such as the National Gallery in London and pricate houses in the United states, such as those by Robert Stern, the re-introduction of historical knowledge and cultural issues to design was merely skin-deep. Regionalism was not the term the architects themselves were reffering to. It was a conceptual device that we chose to use as a tool of analysis. The concept of regionalism here indicated an approach to design giving priority to the identity of the particular rather than universal dogmas. The awareness of a regional architecture as an idiom having a distinct identity and being associated with an identifiable group, and having this association used for further manipulating the groups identity. Goes as far back as ancient Greece. It was the Greeks that in the context of the politics of control and competition between their polis and their colonies used architectural elements to represent the identity of a group occupying a piece of land, or the virtual presence of a group among other groups in a Pan-Hellenic institution such as Delphi or Olympia. Doric, Ionic and Corinthian, were not abstract decorative terms. They originated in the concrete historical context of fission and fusion of regions and identities and their use was frequently loaded with complex political meanings, carving supra-regional identities and relations. The Roman architect and author, Vitruvius, who extensively discussed the Doric or Ionic temples without referring to the term Classical, does refer by name regional architecture, pointing to the difference in building around the world which he explains through climatic conditions and draws a parallel to the variations in the physique of people and concludes that the arrangement of buildings should be guided by locality and climate. In the very end, however, he did not imply regional pluralism and respect for difference. The new global order consists of an effective interconnection of the whole planet by means of a reticular network of communication and exchange. It threatens individual variety and difference throught universalization of practices, but also accentuates the worst of a world of differences. It polarizes further a hierarchical dependance of regional differences rather than encouraging the diversity necessary for creativity. Enhancing a world to come about within which preserving, exploring and mining regional differences brings about a world more genuinely global. The picture of critical regionalism that emerges from these contributions is in great contrast to the simplistic ideas that the local is good by definition, that sustaining community and nature means both blind conservation and resistance to change and that understanding the context is a simple process that requires no special effort or analysis. The traditions are always contested, transformed, resisted and invented. One of the most significant aspects of the quality ofn the built environment whish has been systematically ignored and violated by superficial thinking, biased judgement and seductive illusions is the skin of buildings. The impact of bad choices of materials on the skin of a building is not immediate. It is here that deep knowledge of the materials and the climatic attributes of a particular area is needed that cannot be substituted by reductive technical descriptions and even more by photographic media reproductions. The thoughtless transfer of glass as well as concrete to the tropical region led to indifferent if not hostile environments. American architect Ralph T.Walker, like Mumford, he was highly critical of the older. He spoke out at length, and his comments deserve to be reproduced: I have been around South America recently and I have just came back from Europe, and I find everywhere that modern architecture means a slab on pillars. It means the same thing in the United States because you pick up the architectural magazines and practically every issue has as its leading number a slab on pillars Functionalism of materials has blazed our thinking around the world because you will find that the building in Rio for the Education Ministry looks exactly like a building that was designed for a giraffe in the London Zoo, and it looks exactly like the building that has been designed for the United Nations. In other words, you have a cover of unthinking uncritical acceptance of things. He went on to argue that what was needed was humanism because it is the basis of all art and what we are trying to do first of all is to develop surroundings for people to live in, that will give them the greatest amount of the happiness and warmth of life. The first point on which Mumford broke with older forms of regionalism was in his approach to tradition. Although he ded advocate the preservation of actual historical buildings, notably those built in the vernacular brick tradition of the South, which deserves to be regarded with a far more appreciative eye than people usually apply to it, he was opposed to their imitation in new buildings. Let us be clear about this, the forms that poeple used in other civilizations or in other periods of our own countrys history were intimately part of the while structure of their life. There is no method of mechanically reproducing these forms or bringing then back to life; it is a piece of rank materialism to attempt to duplicate some earlier form, because of its delight for the eye, without realizing how empty a form is without the life that one supported it. There is no such thing as a modern colonial house any more than there is such a thing as a modern Tudor house. The philosophic problem of the general and the particular has its counterpart in architecture; and during the last century that problem has shaped itself more and more into the question of what weight should be given to the universal imprint of the machine and the local imprint of the region and the communitu Mumford in the south in architecture. MEANS every regional culture necessarily has a universal side to it. It is steadily open to influences that come from other parts of the world, and from other cultures, separated from the local region in space or time or both together. It would be usefyul if we formed the habit of never using the world regional without mentally adding to it the idea of universal remembering the constant contact and interchange between local scene and the wide world that lies beyond it. To ideas or technical methods that originate elsewhere as with a human being, every culture must both be itself and transcend itself; it must make the most of its limitations and must pass beyond them; it must be open to fresh experience and yet it must maintain its integrity. In no other art is that process ore sharply focused that in architecture. TO CONSIDER THE ENVIRONMENT MEANS TO CONSIDER HISTORYMUMFORD What we call globalization does not consist of an effective interconnection of the whole planet by means of a reticular network of communication and exhange. In reality, our global worlds structure is rather an atlas of radial nuclei and unplugged areas that keeps large zones of silence. Globalization bears a massive and infinite process of concentration from the peripheries to the centres, almost one half of the worlds population lives today in urban environments. This situation creates multiple physical and mental displacements. Globalization has marked two opposing cultural processes. Their interaction constitutes a critical point in the rearticulations of symbolic power and a paradox that signals the epoch. On the other hand, it constitutes the de post moment of expansion of industrial capitalism, which is part of the extension of Europe and its culture since the Renaissance. This expansion has been narrated as a story of the expansion of the world. The acquisition of worldwide power was seen as a globalization: the local Western became universal through the conquest of planetary power, colonialism and the construction of a totalizing rationality from that power. The idea of expansion culminated in an inverse notion, that of contraction: the world becomes smaller day by day, and even a global village. Western culture was imposed as an operating metaculture of the contemporary world. This was done with the purpose of conversion and domination, but implicity meant generalized access. If imposition seeks to convert the other, access facilitated using this metaculture for the others own, different ends, transforming the metaculture from within. Western metaculture has become a paradoxical means for the affirmation of difference, and for the rearticulating subaltern camps interest in post-colonial times. Hence globalization times are simultaneously those of the difference. This is the other contradictory process to which I referred at the beginning. The existence of an operative metaculture has allowed the globalization of difference beyond the local environments. This cultural globalization implies an interaction between the extended Western metaculture and the cultural plurality of the world. If the first maintains its hemegonic character, the others have taken advantage of its capacity for international broadcasting to supersede local frameworks. Besides, any vast expansion, such as Buddhism in Asia or the Latin language in the Roman Empire, carries a high degree of tension that opens pores and cracks. This globalization-differentation process is an intricate conflictive articulation of forces more than dual dialectics. It implies contaminations, mixtures and contradictions in many directions, although it direct current processes of culture, it cannot be taken passively, as a necessary inclination that occurs without any pressyre exerted by the subaltern sectors. Among other problems, there is the metacultural tendency to generalize practices from many diverse environments from yoga to karate in consumer-driven, culturaly aseptic method as isolated elements of a cosmopolitan mosaic. Nevertheless, some of the most successful experiences in non-occidental regions have consisted, as in the case of Japan, in managing Westernization to their benefit, empowering it from their own different background. It is in this labyrinth of displacements and ambiguities where the current cultural power lies. It becomes more evident that at this point there ir no viable return to pre-colonial traditions, because that would consist precisely of regression to the myth of an unpolluted past with a small margin of action in the contemporary world. The issue is to build the contemporary from a plurality of experiences that are able to transform the metaculture, Even when imposed by a dominant culture over a dominated one, cultural appropriation is not a passive phenomenon. Receivers always transform, resignify and use according to their visions and interests. Appropriation, and especially the incorrect one, is usually a process of originality, understood as a new creation of meaning. Cultural debate ahs become a political arena for power struggle, both in the symbolic and the social aspects. It is seen both in the cultural adjustments that the subaltern and peripheral sectors are making, as well as in the heterogenization that immigrants are causing in the contemporary megalopolis. Every alrge city today is a dynamic crossroads of cultures. There are many and diverse people incorrectly and unabashedly reworking Western metaculture in their own way, de-eurocentralizing it in plural form. What we call postmodernity is, in good measure, the result of overlapping of all these contradictory processes, they also determine an extraordinary dynamic of identities, with complex adjustments: multiple identities, identities in the form of chinese boxes, neo-identities, mixture of identities, displacement among them, ethnic gamesà ¢Ã¢â€š ¬Ã‚ ¦all borders mutate and turn into the critical spaces of our age. The birder and its culture have become paradigms of contemporary cultural processes, but these and other paradigms are at risk of developing into a narrative of harmonization of diversity, leveling contradicitons and masking confrontation of interests. The essay aims to discuss about the loss of cultural identity in this modern society, which lead to the loss of vernacular architecture. Basically vernacular architecture is a category of architecture based on localized needs and construction materials, and reflecting local traditions. It tends to evolve over time to reflect the environmental, cultural, technological and historical context in which it exists. The building methods are tested through trial-and-error by the society as the people constructing the structure tends to be the person who will use it. However, nowadays, people have mistaken the meaning of cultural identity, they tend to re-create the vernacular architecture into a purpose space where the tradition has been reinvigorate to a resort. People have tried to modernize the vernacular architecture, but still, loss of culture identity is the problem or the modern vernacular. What is vernacular architecture in peoples view nowadays? Will people still respect the culture identity? Why is the topic important in the world or in the context of design? As nowadays, vernacular architecture is gradually disappeared in this modern society. People have started to copy the authenticity to attract the ever-increasing tourists. Figures in architecture hence become less to do with a response to materials and more to do with the associative at tributes of particular shapes and forms. Why is this happening? It was because a global homogenization of the culture of the tourists, an excess of material choice, rapid urbanization, emergence economies, global environmental crisis and politics. Architects have tried using the four ways to modernize the vernacular architecture for now which are reinvigorating, reinventing, extending and reinterpreting tradition, however it still leads to the loss of cultural identity. How will architecture recreate a tradition, a shared ground that provides a basis for the criteria of authenticity and quality? How am I going to approach the topic? The essay will take on a critical regionalism approach of how people view on the vernacular architecture nowadays. Making a point to the loss of culture and how vernacular architecture has slowly fade away, shows how people should react to this issue and also to explain when this vernacular architecture be applied again in this modernized society, create spaces of authenticity of a tradition.

Reflective Essay on Structured Interviews

Reflective Essay on Structured Interviews the way you structured the questioningit gave me ideas in my head in how I wanted the interview to go (from interview transcript) Incident: The key point during the interview, I thought, was when J. spoke about how he wanted the interview to go and what questions and information he wanted to find out. For me, J. had reached the point I wanted him to get to, where he realised it is possible to control and change an interview using a structured approach. I suggested to him as further learning to develop in the future, using examples of questions about self harm and suggesting using formal interview tools in informal ways. I did not ask J. what he meant by ideas in my head. I hesitated to ask him what he meant and to encourage him to reflect on this. Reflective observation: Looking over the transcript and analysing it, I think I missed the boat with J. here. I perhaps let an opportunity pass to explore his learning with him in greater depth. We could have discussed how to develop skills in interviewing and what he wanted to learn next. This would have moved the focus away alcohol and withdrawal symptoms towards his skill development. It could also have been a good opportunity to practice critical incident analysis. I think there were two reasons why I was wary of delving deeper at this point with J. and trying to help him reflect on his learning: First, I had not worked with him for two weeks which was unfortunately due to training and holiday schedules. This meant I had no chance to work with him and observe and assess him directly. I had set him guidelines in how to interview and knew he could get support from other staff nurses. However, I had only what he was giving me during the interview to assess and give him feedback. Secondly, I had started the interview with a clear idea that we were going to cover his CAP booklet in some areas. I really felt some pressure inside myself to cover the whole assessment aspect and not risk going off at a tangent. I regarded the purpose of the assessment as giving J. feedback on how he had met his competencies. I knew that most students saw completing their CAP booklets as a priority. Perhaps if I had helped J. explore his learning it may have been more useful for his future. I felt he was interested in the subject and seemed motivated to learn. He reported making several attempts to talk to different patients on the ward about their drinking. He did link what he had learned to his next placement and how he could use it. It is a little ironic that I was not flexible and adaptable in my approach to interviewing. But we were both learning: J. as a student nurse and myself as a student mentor! Related theory: Rowantree (2003) describes six different purposes for assessment: including selection, standards, motivation for students, feedback to students, feedback to teachers, and preparation for life. Selection here can be conceived as both access to a course or profession and passing or completing a course of education. There are number of purposes here which are not necessarily compatible or perhaps easily reconcilable. Selection and maintaining standards can be seen as competitive and even as almost elitist. Feedback is described as the life-blood of learning (Rowantree, 2003: p416), where assessment is meant to teach the student something. Preparation for life can be seen as inspirational which maybe at odds with maintaining standards, in the sense of maintaining a status quo. Jarvis and Gibson (2001) talk about the two common types of assessment current in nursing education: formative and summative assessment. They describe formative assessment as diagnostic to try and find out what the student has learned and still has to learn. Summative assessment is about making a judgement of whether a nurse has learned enough to become competent (Bradshaw, 1989). Duffy and Hardicre (2007) in their first article on failing nursing students describe a three stage process of an initial meeting which is formative; a mid placement meeting which is formative with constructive feedback and a final summative meeting where both the student and mentor should know what to expect. In part 2 on managing failing students they state that feedback should be regular and ongoing (Duffy and Hardicre, 2007). This prescriptive approach to assessment is about meeting standards and ensuring public and patient safety. Even though they are discussing the failing student their approach if used must apply to all students in order to be consistent, fair and balanced. The mentor has to balance the idea of educating and learning with a duty of ensuring that the student is safe to practice. On the one hand the mentor should provide feedback that facilitates the student identifying what they have learned and what they still have to learn. On the other the mentor is accountable for the safety of patients in their care. Beattie (1991) argues that this can make assessment more effective by ensuring consistency to meet the accountability need. This is not easy and involves gathering a lot of information about learning to make a judgement based on this evidence. However, if our aim is to create a profession of reflective practitioners then assessment must perhaps include an open ended formative element as well. Driscoll (Baird and Winter, 2005) makes the point that there is no end-point in learning about practice. Perhaps mentors have to allow their students the freedom to explore their learning. During assessment students should have opportunities to reflect and to broaden their understanding. Students perhaps should be given choice and participation in the learning process. This is in line with teaching nursing students as adults who are internally motivated, self directing and who bring past experience to their learning. (Knowles, 1990) The challenge is to foster this desire and motivation to learn when it occurs. Biggs (1987) discussed the differences between deep and superficial learning. Assessment that encourages anxiety and recall of knowledge can lead to superficial learning. Where deep learning is promoted by motivation to learn and should be more effective in creating professional nurses. One way to foster deep learning could be to use questioning skills. It is possible to ask questions that will broaden learning and develop critical thinking. There are different types of questions: closed; open; questions looking for simple answers; questions that promote discussion. The mentor should form a question at an appropriate cognitive level for the nursing student. The mentor can ask a series of questions aimed at getting a response from the student and encouraging an increasing complexity if appropriate. (Nicholl and Tracey, 2007) In exploring some of the literature on assessment, it seems apparent there are two intertwined elements present: the formative strand is about what has been learned and what still needs to be learned; the summative strand is about making a judgement about meeting a proficiency standard to become professional and safe in practice. The challenge for the mentor is to meet both strands adequately in their assessment of student nurses. Future Action: There are some things I would try and do differently. I would try and structure assessment over the whole placement as suggested in Duffys model (Duffy and Hardicre, 2007). However, I would try and find a place both the formative and summative elements within the assessment process, while trying to clearly have separate interviews for each. I would like to observe my student directly in learning situations, as well as gather information from colleagues and of course from the student. I would now see feedback as having to be based on a sound judgement based on facts in order to be helpful for the nursing student. Even where the student is more senior and capable I would still like to have some element of direct observation to justify my assessment. Another part I would consider is planning my feedback and possibly giving it in writing beforehand. This could remove anxiety on the students part about passing and perhaps allow time to explore formative aspects of the assessment. I think growing as a mentor would involve becoming skilled at encouraging learning during assessment while giving feedback and passing a student or not. If I had another instance like with J. here, I would like to try and ask a few questions to delve a little deeper into what he was saying.
