Laplace Transform Example

Laplace Transform Example Abstract: This paper describes the Laplace transform used in solving the differential equation and the comparison with the other usual methods of solving the differential equation. The method of Laplace transform has the advantage of directly giving the solution of differential equation with given boundary values without the necessity of first finding the general solution and then evaluating from it the arbitrary constants. Moreover the ready formulas of the Laplace reduce the problem of solving differential equations to mere algebraic manipulation. Introduction: Differential equation is an equation which involves differential coefficients or differentials. It may be defined in a more refined way as an equation that defines a Relationship between a function and one or more derivatives of that function. Let y be some function of the independent variable t. Then following are some differential equations relating y to one or more of its derivatives. The equation states that the first derivative of the function y equals the product of and the function y itself. An additional, implicit statement in this differential equation is that the stated relationship holds only for all t for which both the function and its first derivative are defined. Some other differential equations: Differential equations arise from many problems in oscillations of mechanical and electrical systems, bending of beams conduction of heat, velocity of chemical reactions etc., and as such play a very important role in all modern scientific and engineering studies. There are many ways of solving the differential equation and the most effective way is to use the Laplace equation because it provides the easy path to solve the differential equation without involving any long process of finding out the complementary function and particular integral. Solution of differential equation: A solution of a differential equation is a relation between the variables which satisfy the given differential equation. A first order homogeneous differential equation involves only the first derivative of a function and the function itself, with constants only as multipliers. The equation is of the form and can be solved by the substitutio The solution which fits a specific physical situation is obtained by substituting the solution into the equation and evaluating the various constants by forcing the solution to fit the physical boundary conditions of the problem at hand. Substituting gives The general solution to a differential equation must satisfy both the homogeneous and non-homogeneous equations. It is the nature of the homogeneous solution that the equation gives a zero value. If you find a particular solution to the non-homogeneous equation, you can add the homogeneous solution to that solution and it will still be a solution since its net result will be to add zero. This does not mean that the homogeneous solution adds no meaning to the picture; the homogeneous part of the solution for a physical situation helps in the understanding of the physical system. A solution can be formed as the sum of the homogeneous and non-homogeneous solutions, and it will have a number of arbitrary (undetermined) constants. Such a solution is called the general solution to the differential equation. For application to a physical problem, the constants must be determined by forcing the solution to fit physical boundary conditions. Once a general solution is formed and then forced to fit the physical boundary conditions, one can be confident that it is the unique solution to the problem, as gauranteed by the uniqueness theorem. Uniqueness theorem: For the differential equations applicable to physical problems, it is often possible to start with a general form and force that form to fit the physical boundary conditions of the problem. This kind of approach is made possible by the fact that there is one and only one solution to the differential equation, i.e., the solution is unique. Stated in terms of a first order differential equation, if the problem meets the condition such that f(x,y) and the derivative of y is continuous in a given rectangle of (x,y) values, then there is one and only one solution to the equation which will meet the boundary conditions. Laplace in solving differential equation: The Laplace transform method of solving differential equations yields particular solutions without the necessity of first finding the general solution and then evaluating the arbitrary constants. This method is in general shorter than the above mentioned methods and is specially used for solving the linear differential equation with constant coefficients. Working procedure: Take the Laplace transform of both sides of the differential equation using the formulas of Laplace and the given initial conditions. Transpose the terms with minus sign to right. Divide by the coefficient of y, getting y as a known function of s. Resolve this function of s into partial fractions and take the inverse transform of both sides. This gives y as a function of t which is the desired solution satisfying the given conditions. Solving the algebraic equation in the mapped space Back transformation of the solution into the original space. Figure 1: Schema for solving differential equations using the Laplace transformation Some of the examples which demonstrate the use of the Laplace in solving the differential equation are as follows: Example no.1 Consider the differential equation with the initial conditions . Proceeding using the steps given above one has Step 1: Step 2: Step 3: The complex function must be decomposed into partial fractions in order to use the tables of correspondences. This gives By using the formulas of the inverse laplace transform we can convert these frequency domains back in the time domain and hence get the desired result as , Another example of the laplace involving trigonometric function is We want to solve with initial conditions f(0) = 0 and f †²(0)=0. We note that and we get So this is equivalent to We deduce So we apply the Laplace inverse transform and get Periodic functions: In mathematics, a periodic function is a function that repeats its values in regular intervals or periods. The most important examples are the trigonometric functions, which repeat over intervals of length 2Ï€. Periodic functions are used throughout science to describe oscillations, waves, and other phenomena that exhibit periodicity. A function f is said to be periodic if for all values of x. The constant P is called the period, and is required to be nonzero. A function with period P will repeat on intervals of length P, and these intervals are sometimes also referred to as periods. For example, the sine function is periodic with period 2Ï€, since for all values of x. This function repeats on intervals of length 2Ï€ (see the graph to the right). Geometrically, a periodic function can be defined as a function whose graph exhibits translational symmetry. Specifically, a function f is periodic with period P if the graph of f is invariant under translation in the x-direction by a distance of P. This definition of periodic can be extended to other geometric shapes and patterns, such as periodic tessellations of the plane.A function that is not periodic is called aperiodic. Laplace transform of periodic functions: If function f(t) is periodic with period p > 0, so that f(t + p) = f(t), and f1(t) is one period (i.e. one cycle) of the function, then the Laplace of this periodic function is given by The basic concept of the formula is the Laplace Transform of the periodic function f(t) with period p, equals the Laplace Transform of one cycle of the function, divided by (1 − e-sp).Laplace transform of some of the common functions like the graph given below is given by Fig no3:continous graphical function From the graph, we see that the first period is given by: and that the period p = 2. Now So Hence, the Laplace transform of the periodic function, f(t) is given by: Other continuous wave forms and there Laplace transforms are This wave is an example of the full wave rectification which is obtained by the rectifier used in the electronic instruments. Here, and the period, p = Ï€. So the Laplace Transform of the periodic function is given by: Conclusion: The knowledge of Laplace transform has in recent years become an essential part of mathematical background required of engineers and scientists. This is because the transform method an easy and effective means for the solution of many problems arising in engineering. The method of laplace transformation is proving to be the most effective and easy way of solving differential equations and hence it is replacing other methods of solution of the differential equation. The most frequent function encompassed in electronics engineering is continuous function and most of the functions are in the time domain and we need to convert them in the frequency domain, this operation is performed excellently by the Laplace transform and hence its application is further enlarged using it in the solution of the continuous functions.

There is no Universal Utopia Essays -- essays research papers

The idea of a utopia is one which has spanned many millennia. The first example of a utopia was the Garden of Eden, and since then mankind has endeavored to reach this perfect existence, a world without problems, where everyone can abide in peace. Just the word ‘Utopia’ summons up a whole assemblage of images, images which differ from person to person. This is why the concept of a utopia has been so tossed around, because no one can truly say what a utopia is. From Plato's republic in 380BC right up to the modern day, literally hundreds of books have been written, and movies made, all which give differing opinions on what is the perfect world. It is impossible for one person to try to comprehend what would be the perfect utopia in which every person would be happy, so we must consider that perhaps the utopias written about are not meant for the multitudes, but are only supposed to exist in the minds of those who create them. This means that what might be a utopia for one person, may be a dystopia for another, this is because the laws, policies religious beliefs and social issues within any given utopia, whilst they seem fair to the creator, may be completely intolerable to everyone else. Firstly though, we must actually consider what a utopia actually is. Thomas more describes his utopia as being an ordinary place, with normal lands and creatures. But his utopia was created by people, and the laws by which they live, which provide everything that people need to survive, as long as they abide by the laws which are plentiful and strict. This type of utopia is basically communist, where everyone is equal. In this utopian society, there is no money, this means that no one person can feel superior because of wealth, and no one ... ...nd thought about, and there is much conjecture about them, a utopia, regardless of what the dictionary says, cannot truly be defined. Its philosophy can be defined, that is, a perfect state, but no-one has been able to create a utopia that everyone regards as perfect, they have only been able to describe a place that they regard as perfect. That is the essence of utopias, they are not intended to ever actually exist, but are a criterion towards which people are supposed to aim, to grow, to change, to try and reach true perfection where everyone can exist in bliss, almost every society in history has had some idea of this heaven, the Vikings had nirvana, Christians have heaven and Buddhists have their pure spiritual state. Throughout history people have aimed towards this perfection and will continue to do so until either it is reached, or human life ceases to exist.

South African Development Plan Essay -- Urban Development

South Africa is a country in the continent of Africa, located to the south tip as its name suggests. Colonized by the Dutch in 1994, South Africa is seperated into nine provinces and is bordered to the north by the countries: Namibia, Botswana, and Zimbabwe, to the east: Swaziland and Mozambique, while coined in the south east is the country Lesotho, completely surrounded by the territory of South Africa. South Africa is one of the most diverse places in the world, and has eleven nationally recognized languages, whereas most countries only have one (Rosmarin & Rissik, 2003). The black indigenous population makes up a majority of the country while also harboring other ethnic cultures such as: whites, Greeks, Germans, Italians, and Asians (Rosmarin & Rissik, 2003). South Africa has a mixed economy based on its agriculturally fertile lands, mineral resources and tourist attractions. Though there is political and economic stability, the country is still faced with drawbacks such as unemp loyment, poverty, and the AIDS pandemic (OECD, 2008). A development plan is vital for the economic development and growth of South Africa. In an attempt to create jobs and build a unified South Africa, the government should draw up informed policies, budgets, and influential programs to ensure that no citizen is excluded and thus benefit everybody in the country. Indeed, South Africa has the relevant economic and social resources imperative for the realization of all the demands of industrialization (Bond, 2002). Though seemingly prosperous, the social evils hidden in the country are normally impediments to the growth and success of the nation. Without doubt, much of the success of the country is basically a function of the unknown resources in the c... ...ing in South Africa. Such a plan will be instrumental for fostering unity in the region and may increase participation with other countries. Works Cited Rosmarin, I., & Rissik, D. (2003, January).

Factors that influence public trust in government Essay

Trust is an intricate interpersonal as well as organizational construct, which occurs when parties who have certain favorable perceptions of each other allow this relationship to develop and reach the expected levels. Trust is an effective way through which social, economic and political relationship transaction costs can be lowered . In political arena, citizens may either be trusted or distrusted in their capacities to choose elected officials or support for a variety of public policies based on the evaluation of citizen’s competence to make decisions in this domain. Government officials, on the other hand, may be trusted or distrusted in coming up with and implementing public policy, based on the expectations of knowledge as well as the expertise of the officials involved in the policy making process. There is a large proportion of the U. S population that continues to distrust the government in spite of the presence of an assortment of programs aimed at restoring public trust in government . Lack of trust in government by the people is strongly associated to the way people feel concerning the overall state of a country. Read more:Â  Influences that affect children’s development essay Even though personal satisfaction is slowly increasing and confidence in local and national government is increasing due to presence of a thriving economy, restoration in addition to maintenance of public interest remains a major and challenging objective . Regardless of the fact that the national mood and trust in the government have increased since the mid 1990s, a considerable proportion of the United States citizens is still highly unsatisfied with the status of the nation, an aspect that lowers their trust in government . Besides persistent worry concerning the moral health of American society, a factor that lowers the satisfaction of the people to the state of the nation, lack of contentment with the honesty of the elected officials is another major factor that leads to distrust of government. A variety of ethical concerns are now lowering the positive attitudes of the American people towards the government. Dissatisfaction with political leaders is one of the most important factors that result in lack of trust in government by the people . This is due to the numerous criticisms of the way politicians, who form the functional part of the government, carries out their duties. However, there is no clear indication that discontentment and distrust with the government are near a crisis phase . The public desire to be served by government officials has remained steady for more than three decades. Distrust and discontentment with the government has not resulted in disregard for nation’s laws. It also does not erode patriotism or discourage public officials from carrying out their duties. Even in times when public trust in government has gone down, a percentage of the population still recommend a government job to their children. Lack of trust in government does not imply that the public is angry at it; rather it implies that the level of frustration emanating from poor delivery of services by government officials is very high. Increase in the level of frustration deteriorates the quality in addition to the nature of dialogue between the Americans and their leaders. Factors that influence public trust in government Lack of trust in government by the people is one disastrous factor that can negatively impact on the functioning of the government. This is due to the fact that numerous governmental activities call for cooperation between the government and the people. Without the cooperation of the people, it would be totally impossible for the government to implement some policies . Besides challenges in implementation of policies, distrust in government has got other adverse consequences. Some of these negative consequences are that voter turnout during presidential elections has become significantly low . In democratic nations, the trust of the people in government is a major factor that contributes to the growth of economy in addition to providing a base on which political leaders can make rational decisions. The magnitude of public trust in government influences the ability of the government to generate the revenue required to support public programs . However, it can also be considered as disastrous factor for people to totally trust the government without questioning its operations. Putting total trust in the government may result in the government degenerating into making ineffective and bad policies. In a number of studies conducted by the Pew Research Center for The People and The Press to determine the factors that result in distrust in government, Americans were revealed to be less critical of the government in various ways as compared to the way it was in the previous decades . Even though these studies revealed increased distrust in government by the people, evaluation of public workers and specific government departments found out that the delivery of services had improved drastically over the last few years. These studies revealed that only a few people criticize the federal government as compared to the case in the 1990s, when the government was regarded as inefficient, wasteful, unresponsive and too stringent. The numbers of those who think that business operations are negatively affected by the strict regulation strategies employed by the government were also revealed to have dropped. Nevertheless, distrust of government by the American population remains substantial, only less than 40% of the population maintains its trust in the government all the time . More than 50% of the population makes it clear that they are frustrated by the government rather than angered by it . Currently, in the United States as revealed by Pew Research Center for The People and The Press, more people have trust in local government than they have in federal government . This is a factor contrary to the way it was about two decades ago, when Americans were more contented with the federal government than with the local government. Trust in state and local government has however grown considerably along with considerable reduction in trust in federal government . Pew Research Center surveys however did not reveal presence of adverse consequences to the country as a result of distrust in government. One of the major factors that influence the public trust in government is the mode of operation of the politicians who lead the government. Failure of elected officials to serve the public in accordance with the interest of the people results in decline of public trust in government. Incompetence of elected officials also results in deterioration of public trust in government. Public trust in government comprise of expectation of fiduciary obligation and responsibility . The perception of fiduciary responsibility is grounded on the belief that some people in society have moral obligation as well as the responsibility to express special concern for interest of others above their own. In policy development, fiduciary obligation is illuminated by the expectation that politicians and other public officials will develop policies that will benefit the public in addition to making decisions based on the interest of the public rather than on personal and partisan gains . Citizens willingly go along with policies they regard as convenient and made within a legitimate process. On the contrary, citizens do not go along with policies they regard as problematic and developed within illegitimate procedures . Development of policies is therefore a major factor that determines whether the public will have trust in the government or not. Various factors that emanate from the developed policies may also lead to development of or decline in public trust in government. These policy outcomes include: peace, prosperity, in addition to other desirable aspects that are associated with public satisfaction with the services of the government . The direction of the country is the other factor that determines the level of public trust in government. Perception that everything is going in the right direction results in increase in trust of public trust in government. On the contrary, if citizens perceive that everything the government does in addition to the direction of the country is not headed in the right direction; they may lose their trust in government. In addition, public perception that the government officials are to blame for the adverse circumstances that lock the country, may result in a decline of public trust in government . The ability of the government to provide security to the public is another factor that can increase public trust in government. The public elects public officials expecting them to come up with policies and strategies aimed at generating and maintaining security of the nation. Failure to develop security policies lowers public trust in government, whereas development of security policies in addition to implementation of these policies results in augmentation of public trust in government. A government that does not guarantee security to its people should not expect the public to have trust in it . Reverence to the rights of individuals is the other factor that greatly influences the trust of the public in government. Citizens look upon the government to protect them from violation of their rights. If a government is characterized by rampant violation of the rights of citizens, it should not expect to have public trust in it. People highly detest government officials who violate their rights. Public trust is very low in a government that does not guarantee protection of the rights of individuals who make up the greater community. Nevertheless, public trust in government increases when government officials respect the rights of citizens. Economic trend is the other factor that can greatly affect the level of public trust in government. The public looks upon the government to come up with strategies aimed at providing a base for economic growth. Failure of the government to develop such policies destroys its trust by the public. Research conducted by Pew Research Center survey concerning public trust in government make it clear that the trust of Americans in their government tend to increase at times when the country is enjoying economic growth and decline when the country is going through economic recession . Presidential approval is the other factor that may influence public trust in government. Perception that the president is incompetent and does not handle national matters in an appropriate manner may result in a decline in public trust in government. The president occupies a core position in government and as such, he/she is subject to public scrutiny. If the public is contented with the way the president handles national matters, its trust in government is likely to increase. Presidential approval is based to a great extent on economic growth. The public tends to lay the blame of emergence of adverse economic conditions such as lack of employment, inflation and loss of jobs on the president. High rate of unemployment results in decline of public trust in government . The mode of service delivery by civil servants is a major factor that may destroy or build public trust in the government. This takes into account the mode of delivery of service in numerous government sectors including health, education, welfare, transport, security, and environment among many others. Higher values of public contentment with the mode of service delivery by public service officials illuminate trust in government by the people. Accountability of the government also influences public trust. Implementation of strategies that allow for easy access to government information in order to evaluate performance and results is the other factor that influences public trust in government. A large proportion of the public’s trust rests on the government’s open accountability for its decisions, policies and mistakes . A government that operates in privacy and refuses to reveal its mode of operation to the public is in essence getting rid of the public’s capacity to scrutinize as well as hold the government accountable. Access to information concerning the government’s mode of operation and outcomes of various government activities, is vital to increasing the capacity of the public to scrutinize the performance of the government in addition to holding the government responsible. Lack of information implies that the public cannot comprehend the context in which decisions on national matters are made . Government’s accountability builds public trust in it due to the fact that information concerning the performance of government officials is disclosed, and strategies through which waste, inefficiency, misconduct and corruption can be tackled are developed . Conclusion It can therefore be concluded that there are numerous factors that greatly influence the public trust in government not only in the United States, but throughout the world. Lack of trust in government by the people is one disastrous factor that can negatively impact on the functioning of the government. Putting total trust in the government may also be disastrous as it may result in the government degenerating into making ineffective and bad policies. One of the major factors that influence the public trust in government is the mode of operation of the politicians who lead the government. The direction of the country is the other factor that determines the level of public trust in government. Perception that everything is going in the right direction results in increase in trust of public trust in government. The ability of the government to provide security to the public is another factor that can increase public trust in government. Reverence to the rights of individuals is the other factor that greatly influences the trust of the public in government. Citizens look upon the government to protect them from violation of their rights. Economic trend is the other factor that can greatly affect the level of public trust in government. The public looks upon the government to come up with strategies aimed at providing a base for economic growth. Failure of the government to develop such policies destroys its trust by the public. The mode of service delivery by civil servants is a major factor that may destroy or build public trust in the government. Bibliography: Braithwaite, Valerie and Levi, Margaret.

Depression Among The Hiv Victims Health And Social Care Essay

The survey aims at mensurating the degrees of depression among the HIV victims. The sample consists of two groups of the same gender i.e. adult females, viz. married and single ( individual ) adult females, between the age group of 25 to 35. Hence, the sample comprises of 60 adult females, 30 of each belonging to get married and single ( individual ) class severally. The sample besides belongs to the patients fit in to the governmental rehab centre, and they are being administered by the research worker through the standardised questionnaire – depression graduated table designed by Aaron T. Beck. The scale touches assorted facets like temper, , self-dissatisfaction, guilt, self-destructive thoughts, societal backdown, pessimism, sense of failure, deficiency of satisfaction, guilty feeling, sense of penalty, self hate, self accusals, self-punitive wants, shouting enchantments, crossness, indecision, organic structure image, work suppression, sleep perturbation, fatigability, lo ss of appetency, weight loss, bodily preoccupation, and loss of libido. Introduction Everyone feels down or at loss at some clip or the other during his or her life. In fact, ephemeral feelings of unhappiness or disheartenment are absolutely normal, peculiarly during hard times. Life is full of emotional ups and downs. But when the â€Å" down † times are long lasting or interfere with an person ‘s ability to map, that individual may be enduring from a common, but terrible emotional reverse which is universally known as depression. ( NIMH ) .Depression is an unwellness which involves the organic structure, temper and ideas which affect the manner a individual chows and slumbers, the manner one feels about oneself and the manner one assumes about things. Depression is a province of low temper and repulsion to activity. ( NIMH ) A down individual might hold one or any of these inclinations like experiencing sad, dying, empty, detering, helpless, worthless, guilty and frequently loses involvement in activities which were enjoyable to them earlier. They migh t besides hold symptoms like loss of appetency or over feeding and even self-destructive ideations. depression is an change in temper which affects a individual ‘s ability to work twenty-four hours to twenty-four hours. ( NIMH ) In the most up-to-date study from 2000, the World Health Organization ( WHO ) reported that depression is the 4th most onerous disease in the universe, with more than 120 million people enduring from it worldwide and it is expected that by 2020 it will be the taking planetary disease load ( WHO ) . Depression can look at any age. Anybody can see depression, be it adolescents, teens, grownups and if looked from the gender position, both work forces and adult females. However, Womans are more likely to go more down than work forces. Womans are about twice every bit likely as work forces to see depression. â€Å" Womans are genuinely more down than work forces, chiefly due to their experience of being female in our modern-day civilization † ( Dr. Ellen McGrath, a psychologist in Brooklyn Heights ) . As with other serious unwellnesss such as malignant neoplastic disease, bosom disease or shot, nevertheless, HIV frequently can be accompanied by depression. Depression is a really common status for people with HIV ( Depression and HIV, October 12. 2009, AIDS info ) . HIV ( human immunodeficiency virus ) is a lentivirus which is a member of retrovirus household, that infects cells of the immune system, destructing or impairing their map. It causes AIDS ( acquired immunodeficiency syndrome ) , a status in worlds in which the immune system begins to neglect taking to life- baleful timeserving infections. The infection with HIV occurs due to the transportation of blood, seeds, vaginal fluid, pre- semen or chest milk. The four major paths of transmittal are insecure sex, contaminated acerate leafs, chest milk and transmittal from an septic female parent to her babe at birth ( perpendicular transmittal ) . HIV in worlds is considered pandemic by the World Health Organization ( WHO ) .HIV adult females are more likely to be depressed in comparing to work forces ( adult females and depression, November 2009 ) AIDS continues to be a major planetary wellness priority.The figure of people populating with HIV worldwide in 2008, was around 33.4 million, Of which the adult females constituted of 15.7 million.The entire figure of people populating with the virus in 2008 was more than 20 % higher than the figure in 2000. Asia which is place to 60 % of the universe ‘s population, and is following to the sub-Saharan Africa in footings of people populating with HIV ( 4.7 million ) in 2008. India being one of the most populated states of the universe, approximately half of Asia ‘s HIV prevalence. The proportion of adult females HIV rose from 19 % in 2000 to 35 % in 2008. It is estimated that around 2.3 million people are presently populating with HIV. ( UNAIDS ( 2008 ) ‘India: State Situation ‘ ) Theoretical base HIV being the deathly disease, researches have been go arounding around it. Surveies have been done in relation to depression and HIV ( Rabkin J, Rabkin R, New York State Psychiatric Institute, New York, NY. ) where the per centum of HIV-positive agony from depression and the badness of depression was measured. A survey found that depression was under-diagnosed among HIV-positive patients which was associated with emphasis, solitariness, low attachment, and insecure sex ( Depression in Patients With HIV Is Under-Diagnosed: A Cross-sectional Study in Denmark February 17, 2010 ) . Depression is common in people with sexually transmitted infections, a Canadian research workers study in the December edition of Sexually Transmitted Infection ( Michael Carter, Published: 18 December 2008 ) . The survey had 21500 individuals,15-49 old ages of age and it showed 8 % were sick persons of depression and work forces were less likely than adult females ( 6 % and 10 % severally ) . Some other rese arches aound this subject are Other reseaches are fects of Quality of Life and Coping on Depression among Adults Populating with HIV/AIDS ( C. Gore-Felton, C. Koopman, D. Spiegel, M. Vosvick, M. Brondino, and A. WinninghamEf, J Health Psychol, SeptemberA 1, A 2006 ; 11 ( 5 ) : 711 – 729. ) ; Use of Selective Serotonin-Reuptake Inhibitors in the Treatment of Depression in Adults with HIV ( J. Caballero and M. C NahataAnn. Pharmacother. , JanuaryA 1, A 2005 ; 39 ( 1 ) : 141 – 145. ) ; Predicting Fatigue and Depression in HIV-Positive Gay Men ( J. Barroso, J. S. Preisser, J. Leserman, B. N. Gaynes, R. N. Golden, and D. N. Evans, Psychosomatics, AugustA 1, A 2002 ; 43 ( 4 ) : 317 – 325. ) ; Depression among Patients with HIV/AIDS: A Treatment Dilemma ( G. P. Overman and S. L. Anderson, Journal of Pharmacy Practice, DecemberA 1, A 2001 ; 14 ( 6 ) : 540 – 550.0 ) . Depression kills HIV/Aids patients faster than the virus within them ( Nirmala M Nagaraj, Bangalo re, TNN, Dec 1, 2009 ) . It has besides proven that depression degrees are more in HIV+ adult females than HIV+ work forces ( Women and Depression, November 2009, but the matrimonial position of adult females had n't been touched yet, hence research is ought to be done. Methodology The Beck ‘s Depression Inventory ( BDI ) , designed by Aaron. T. Beck, is being used to mensurate the degrees of depression among the HIV victims. It consists of 21 inquiries, each designed to measure a specific symptom common among the people with depression. BDI is divided into two chief subdivisions viz. , one comprising with the inquiries pertinent to emotional symptoms and the other incorporating inquiries pertinent to physiological symptoms. However, a 2nd version of the stock list ( BDI-II ) was besides developed but the 1st version of it is being personally administered by the research worker to the samples. The sample comprises of 30 adult females between the age group of 25-35, belonging to two different classs, married and single ( individual ) severally. Evaluation The critical rating has encounterd the undermentioned restrictions, and the survey would be executable because entree to the patients would be a officially permitted attack as the research worker would be provided with an hallmark missive from its establishment, which could be presented to the rehabilitation centres. Decision Depression though is common in both work forces and adult females, depression in the latter affects the household straight at that place by the society adamantly, peculiarly in India, where adult females are ever viewed weak and low-level to work forces. They are the more ignored slot and besides face terrible societal stigma in the society. Hence, this subject could keep good range in groking depression in adult females, and an effort is being made to switch the cogwheels towards the encouraging and soothing of the adult females victims.

POLC in the School System Essay

Just like any other organization, a school system would not be able to function properly without an efficient administrator and an effective administration process. In the case of school systems, the administrator would be the superintendent of the school. As the administrator, the superintendent serves as both the leader and the manager of the school. In order to be a successful and efficient administrator, the superintendent should focus on four areas– planning, organizing, leading, and controlling. In the case of planning, the administrator should be able to pinpoint appropriate goals for the whole school system. The goal usually carries prospects for progress, equality, and harmony. As part of the planning process, the administrator should also be able to identify the best courses of action in fulfilling the chosen goals. Such goals should be evaluated at a regular basis so as to assess if they are ion line with the demands of time. After planning the goals and the ways towards its achievement, the administrator should be able to put those plans into action. Organizing is as important as the plan itself. As such, the new administrator should be able to formulate task and authority relations. He should be able to establish an organizational set-up that will allow the school system to efficiently and quickly make the vision, a reality, if he/she may deem the present set-up is inappropriate. As the leader of the school, the new administrator should also be able to influence people- from the students to the teachers, and even the other sectors involved in establishing an effective educational system such as the community, the parents, governmental agencies, and many more. He or she should be able to motivate and unite them, and provide them with a common goal for the educational welfare of the students and for the encouragement of harmony and efficiency of learning and teaching processes. He or she should be able to encourage everyone to work towards a common goal, which is usually the mission and vision of the school. Lastly, after ensuring the plans, the set-up and the people are all set for action; the administrator should be able to control the organization. Control should not be equated with stringent and numerous laws and regulations matched with various sanctions. Instead, it should be associated with the establishment of precise evaluation processes that will allow the administrator to measure and monitor the organization’s development at regular basis overtime, in accordance with the established goals.

Legalizing same-sex marriage Essay

Eliyahu Stiefel Mr.Hong English 1A 02/02/2012 Legalizing same-sex marriage has been a debate going on for quite some time. The recognition of such marriages is a civil rights, political, social, moral, and religious issue in many nations. Since 2001, ten countries have begun allowing same-sex couples to marry nationwide. In the United States the federal government does not recognize same-sex marriage, but such marriages are recognized by some individual states. Proposition 8 in November 2008 state elections, was a ballot proposition passed in California eliminating the right of same sex couples to marry. The measure added a new provision, Section 7.5 of the Declaration of Rights, to the California Constitution, which provides that â€Å"only marriage between a man and a woman is valid or recognized in California. I will argue that same-sex marriage should be legalized as it does nothing to impede on heterosexuals and that same-sex marriage can possibly have very positive effects on society. I will also suggest that perhaps decisions such as same-sex marriage should not be under government jurisdiction and perhaps marriage altogether should be privatized. Legalizing same-sex marriage according to some opinions can have a very positive effect on society. Jonathan Rauch an avid proponent of same-sex marriage and author of Gay Marriage writes, †For gay couples, it will bring the stability and healthiness and happiness that marriage uniquely provides. For straight people it will bring all of the benefits of social stability that goes with marriage.†(Rauch) According to Rauch legalizing same-sex marriage can bring great benefits to society. Marriage causes people stay in more committed relationships, and when people are in committed relationships there is less promiscuity. A culture of marriage for gay people might not have stopped the [AIDS] virus altogether, but it certainly would have slowed the virus down, and saved who knows how many lives and who knows how much money and agony. Aside from the benefits that same-sex marriage can have on our society, the benefits that will reach the children of same-sex couples is also an important factor. Rauch estimates the number of children being raised in gay households to be around half a million. If society cares about marriage only for the sake of children, this is a large enough number to mean that, it ought to care about the many thousands of children in gay households. Children now being raised in gay households, feel left out because they don’t feel like a family since their parents are not permitted to be married. This is why many people feel that legalizing same-sex marriage will have no negative effect on society, and can in fact have a very positive effect on society. A great solution to the same-sex marriage debate would be to privatize marriage. Marriage contracts should not be written by the government, rather they should be written and agreed upon by the parties involved, and they should be enforceable by law. Lawrence Stone a historian noted for his work on marriage writes: â€Å"In the early Middle Ages all that marriage implied in the eyes of the laity seems to have been a private contract between two families. †¦ For those without property, it was a private contract between two individuals, enforced by the community sense of what was right.† (qtd Boaz) According to Lawrence Stone, marriage was always a contract between two individuals or two families that was created by them and enforced by the community based on what they felt was right or wrong. Privatizing marriage would therefore bring us back to the traditional way of marriage and would allow people to make decisions based on what they feel is right or wrong. In our society where the dissolution of a marriage is treated in much the same way as the dissolution of a business partnership; why not make the creation of marriage similar to the creation of a business partnership; agreed upon by parties involved and enforceable by law. Colin P.A. Jones a U.S. lawyer and professor at Doshisha University Law School in Kyoto, Japan suggested an idea on privatizing marriage: â€Å"Even greater efficiencies might be achieved through the establishment of marital corporations (MCs), each having hundreds or thousands of couples as stockholders, all sharing common values about marriage. Couples getting married would subscribe to the shares of an existing MC, whose charter documents would set forth the terms of the type of marriage to which the subscribing couples agree.† With this system all types of marriages would be available based on what MC you decided fits your moral standards. For some it may be a corporation that accepts same-sex marriage and for some it may be a marriage without any divorce solution. Governments and corporations may limit the types of MCs that they recognize for benefits purposes; however these decisions of what corporations to accept for benefits, would be based solely on what would benefit the economy and society. Also in 2006, Jewish libertarian Michael R. Paley author of When Secularism Becomes a Religion advocates the privatization of marriage, saying that the expression â€Å"holy matrimony†, ought to place marriage in the sphere of community, not state† Judaism agrees with the separation of community and state, at least until the Messianic Era; religious matters such as marriage ought to be within the jurisdiction of private religious officials, not public, civil ones. According to these opinions the same-sex marriage debate can be easily solved by privatizing marriage. According to some, legalizing same-sex marriage can have longtime negative effects on society. In today’s society we already experience the negative effects from unhealthy heterosexual marriages and divorces. By legalizing same-sex marriage we will just add to the instability that already exists in marriages. Legalizing same sex-marriage would tell society that marriage in general is â€Å"optional.† Giving people the option of same-sex marriage would change the definition of marriage. Marriage used to mean two people getting together in order to create a family, marriage will no longer be the creation of a family, but simply a confirmation of a relationship, or a commitment ceremony, with little meaning, and that would therefore cause fewer people to marry. With fewer marriages, the number of children being raised by single parents would increase. Research shows that children tend to do better when being raised by their two biological parents. While gay marriage would encourage adoption of children by homosexual couples, which may be preferable to foster care, some lesbian couples want to have children through anonymous sperm donations; this means that some children will be created purposely without knowledge of one of their biological parents. According to these opinions, legalizing same-sex marriage can therefore possibly cause negative effects on society. According to many opinions marriage privatization will not solve the debate on same-sex marriage. Opponents of marriage privatization argue that such a policy will simply shift the current debate over same-sex marriage to what kind of marriages the government should accept for benefit related purposes. Religious opponents of same-sex marriage feel that privatizing marriage and allowing people to create their own marriage contracts would be an endorsement of what they consider to be immoral unions between homosexual couples. Thus many of the same religious arguments aimed against same-sex marriage will still be applied to marriage privatization as well. Even if marriage contract were exclusively agreed upon between consenting adults, the vast types of contracts and corporations that administer these contracts would be so enormous, that it would be impossible for government to enforce these many different types of marriage contracts that would come about. This is why many people would agree that marriage privatization would not be the solution for the same-sex marriage debate. I would argue that these people that say that gay marriage will have a bad effect on society are wrong. We find these days those children who grow up in homes where they weren’t raised by their biological parents still end up growing up just as normal as children who are raised by their non-biological parents. The number of children that would benefit from legalizing gay-marriage by far outweighs the hypothetical negative effects that some say legalizing same-sex marriage would do. In a study by various pediatricians in 2005 on the effect that gay parenting has on their children. â€Å"In a Specific Census 2000 there are findings that in 96% of counties across the U.S., gay couples are raising children†, (Pediatrics Vol. 118) children raised by homosexual parents typically develop in ways that cannot be distinguished from their peers raised by heterosexual parents. In the study’s own words, â€Å"in fact, growing up with parents who are lesbian or gay may confer some advantages to children. (Pediatrics Vol. 118) They are described as more tolerant of diversity and more nurturing towards younger children than children raised by parents that are heterosexual. The benefit to the children is of primary, and the benefits of coming from a stable, committed, loving home are incredible and un-doubtable. Other aspects reviewed include the effect on the economy, which are startlingly positive. By allowing same sex couples to marry, the federal government would receive an additional $400 million in federal income tax revenue. With this study we can see that those who try to say that legalizing same-sex marriage will have a negative effect on society are wrong. I would like to conclude with saying that as a Jewish religious person it would be very easy for me to point out that the Torah forbids homosexuality and therefore my opinion would be that gay marriage should be absolutely unacceptable. However in America where we have many cultures and many different types of people with different ways of thinking their needs to be room for more than one way of life. Ethnocentrism throughout time has caused many hateful wars and there needs to be a way for people to reach agreement on issues like same-sex marriage which is a very strong issue in America. I would therefore hold the opinion that legalizing same-sex marriage does nothing to interfere with the rest of society. Ultimately the best thing that could happen to solve the same-sex marriage debate would be government taking itself completely out of the marriage business, and handing it over to the private sector.
