People Living With Hiv Health And Social Care Essay

People Living With Hiv Health And Social Care Essay HIV/AIDS is one of the most challenges to human life and dignity. It affects all levels of the society and has a massive impact on global economic and social development, (Rowden, 2009). Studies have been conducted on its impact on human life and how it could be controlled. This review was conducted by visiting a number of websites of different publishers and organisations for published articles on HIV/AIDS and stigma. Literature covering a period of 8 years from 2002-2010 was extracted from Assia, PubMed, Sage, British Medical Journal, Cochrane and Absco-host. However due to the topic in question, literature from most recent articles would have been preferred. The term HIV/AIDS stigma was used to capture a wide range of articles covering all areas of the globe. Abstracts from twenty studies were reviewed for the study, objectives, methodology and key findings. Twelve studies covering different locations of the world were chosen. Relevant documents and reports from other organisation s such as UNAIDS, WHO and the World Bank were also reviewed. Both qualitative and quantitative data was used to present the information. Due to the challenges presented by HIV/AIDS to global public health, Baum. (2008:241) calls for collective participation of all sectors in the fight against this deadly disease. Baum emphasises on the collective participation between the lay people and the health structures as key to success. This is further supported by Farmer, (1999), who does not condone the dominance of the biomedical perspective in health and healing. He believes that lay people have a significant role in the process of health improvements and emphasises on the importance of listening to, and understanding the lay peoples experiences of ill-health and how it is affected by their daily lives. Goffman, (1963), and Parker and Aggleton, (2003),s theories of stigma help us to understand how stigma is constructed and its influence in peoples lives. They view stigma and discrimination as functional systems which maintain boundaries between those in power and those without. Through such power, social inequalities are developed leading to creation of social norms. These formulate stigma by governing interactions between people and reinforce power structures that serve to isolate those that are regarded as outsiders, ( ). Both theories have been widely used in HIV related stigma to highlight how the prejudice, negative attitudes, abuse and maltreatment directed towards people living with HIV/AIDS have hindered the progress of prevention and treatment. Findings from the studies highlight the significance of lay people for prevention and treatment of HIV/AIDS to be effective. In Tanzania, the study unveiled some discriminatory and stigmatised practices such as gossiping about patients HIVs status, neglect, verbal abuse, testing and disclosing HIVs status without consent, (Tanzanias Stigma Indicators Field Test Group, 2005). Similarly in India, health workers were disclosing patients HIV status to their families without the patients consent, (Journal of Social Aspects of HIV/AIDS, 2007). Harassment, avoiding and isolation of HIV-positive patients and testing without counselling are common features of stigmatisation in most studies. Findings showed that stigma and discrimination in health care settings contribute a great deal in keeping people away from accessing HIV/AIDS treatment and care, therefore compromising their health and wellbeing. Patients felt greatly affected by the health workers feeling uncomfortable with them and treat ing them in an inferior manner. Some health workers wore protective clothing even if there was no physical contact during interactions. This affected peoples willingness to access the services despite it being vital to their health. The fear of being identified as infected with HIV was one of the reasons why some people prolonged testing for HIV even though they had the symptoms and only accessed services when their illness was at an advanced stage, (Bond, Aggleton, 2002, Human Resources of Health, 2007, Kinsler et al, 2007, Varga, Sherman, Jones, 2006, Kalichman, Simbayi, 2003). In Zambia, HIV-positive health workers were hiding their HIV status from their colleagues in fear of being stigmatised, (Dieleman et al, 2007). Experienced and perceived stigma and discrimination revealed by the studies have severe influence on people living with HIV/AIDS access to health services. While most of the literature on HIV/AIDS and stigma and access to health services is negative, research also highlights increasing evidence of the value of supportive and de-stigmatising HIV services in some parts of the globe. Brazil has been viewed favourably by people living with HIV/AIDS. The lay people reported supportive inclusive structural systems that create healthy environments for all. The success story of Brazils effective HIV/AIDS and stigma prevention and control is attributed to active participation of different groups in the society and the Brazilian government, (Caltado, 2008). Another success of collective efforts of the lay people and the health structures has been noted in South Africa where most people believe in traditional healing. Aids Activism in South has made a positive significance in HIV/AIDS preventing and treatment by translating and mediating the biomedical approach within local ideological frameworks which are easily understood and acted on by the loc als, (Colvin, Robins, 2010). From the research findings it is clear that collaboration between the lay people and the biomedical approach to healing is essential for successful control of HIV/AIDS and stigma. There is no cure for AIDS but Anti-retrovirals (ARVs) can prolong life by keeping the level of HIV in the body at low levels therefore delaying the process between HIV and AIDS, (Robin, 2009). While ARVs are now readily available in most countries, concerns are mostly centred on the rising numbers of newly infected people. According to the World Bank, 60 million people are living with HIV/AIDS worldwide. Access to treatment has increased dramatically but for every 100 people on treatment, 250 become newly infected, (www.worldbank.org/EOL81VLA20 ). For this reason, pressure in now rising on the effectiveness of only relying on the biomedical approach as a concept of health and healing HIV/AIDS. Diseases such as HIV/AIDS need to be tackled using both the biomedical approach and the lay perspective for prevent ion and treatment to be effective. The shortfall of the biomedical approach to treatment lies on its focus that is restricted to the physical illness of an individuals body and the scientific understanding of disease therefore making the approach heavily based on pharmacology. While pharmacology is beneficial in the treatment and prevention of HIV/AIDS, it benefits the pharmaceutical industry which has also been critiqued as hindering the progress on controlling HIV/AIDS. Pharmacology further promotes the privilege of the biomedical model which may be inappropriate to the communities and create feelings of helplessness and vulnerability. This may contribute to the undermining of alternative approaches to treatment and prevention, (Global Health Watch, 2008, Rowden, 2009, Farmer, 1999). Such interventions are not successful in nations who believe in indigenous forms of healing, for example the dependency on traditional healing in Africa. The lay approaches to healing are effective because they are embedded within local social and cultural structures, but as with HIV/AIDS care, this cannot be confirmed as true. Unlike in the biomedical approach, indigenous approaches seek to heal the whole person by linking the illness with the persons social and economic background. In South Africa, despite people heavily relying on traditional healing approaches, the HIV prevalence continued to rise. Significance towards effective control of the epidemic has been noted with the increase in accessibility of ARVs, (Colvin, 2009). In the UNAIDS report on global AIDS epidemic 2010, in 7 countries, five of them in Eastern Europe and Central Asia, HIV incidences increased by more than 25% between 2001 and 2009. Sub Saharan Africa, although still remaining the most highly affected by the epidemic, figures either stabilised or showed signs of decline owing to positive behaviour due to increased services that are embedded in local culture. T he report affirms that stigma and discrimination, lack of access to services and bad laws can make the epidemic worse, (www.unaids.org/globalreport/Global_report.htm). The attribute to increased incidences in Europe and Central Asia could be on the countries reliability only on the biomedical model of healing. Baum, (2008) asserts that community level mobilisation where there is partnership between the lay people and structures is the effective way of combating HIV/AIDS and stigma. Active participation of lay people will not only promote individual level responses to dealing with the stigma, access to care and preventing of HIV/AIDS but could also go a long way in improving global public health, (Parker and Aggleton, 2003). Improving health care services and making them accessible to people living with HIV/AIDS without fear of being stigmatised, educating health care professionals about the impact of stigma on patients and policies that encourage inclusion of people living with HIV/AIDS in decisions that affect their lives are some of the key factors of effectively tackling the epidemic, (Farmer, 1990:90). Advocacy is another way lay people engaged to improve the relationship between health structures and people living HIV/AIDS. The Greater Involvement of People Living with HIV/AIDS, (GIPA), formally adopted as a principle at an AIDS Summit in 1994 emphasises the need for involvement of people living with HIV/AIDS at all levels in the fight against the disease. According to UNAIDS, people living with HIV/AIDS understand their situation better therefore their voices could be heard well if their needs were presented by people in the same situation, (www.unaids.org). In the Zambia study, with supportive structures, the professionals living with HIV/AIDS are in a better position to advocate for people accessing services. Baum, (2008:550) claims that advocacy involving public health practitioners is an effective way of influencing structural barriers in public health. Both the biomedical and lay perspective approaches to health, healing and prevention of HIV/AIDS and stigma have both benefits and limitations. There is therefore the need for holistic approaches that collaborates both models for HIV/AIDS and stigma interventions to be effective. HIV/AIDS has claimed a lot of lives and continues to claim more; through collective action of the societies and the national structures the epidemic could be controlled.

Emily Dickinson :: essays research papers

Dickinson, Emily Elizabeth (1830-1886), America’s best-known female poet and one of the foremost authors in American literature. Born in Amherst, Massachusetts, Dickinson was the middle child of a lawyer and one-term United States congressional representative, Edward Dickinson, and his wife, Emily Norcross Dickinson. From 1840 to 1847 she attended the Amherst Academy, and from 1847 to 1848 she studied at the Mount Holyoke Female Seminary in South Hadley, a few miles from Amherst. Dickinson remained in Amherst, living in the same house on Main Street from 1855 until her death. During her lifetime, she published only about 10 of her nearly 2,000 poems, in newspapers, Civil War journals, and a poetry anthology. The notion that Dickinson was extremely reclusive is a popular one, but it is at best a partial truth. Although she never married and certainly became more selective over the years about the company she kept, Dickinson was far more sociable than most descriptions would ha ve us believe. Biographers are increasingly recognizing the vital role of Dickinson’s sister-in-law, Susan Dickinson, in her writing. For more than 35 years the two women lived next door to each other, sharing mutual passions for literature, music, cooking, and gardening. Emily sent Susan more than 400 poems and letter-poems, twice as many as she sent to any other correspondent. In 1998 Open Me Carefully: Emily Dickinson’s Intimate Letters to Susan Huntington Dickinson was published, documenting the two women’s friendship. Dickinson enjoyed the King James Version of the Bible, as well as authors such as English writers William Shakespeare, John Milton, Charles Dickens, Elizabeth Barrett Browning, George Eliot, and Thomas Carlyle. Dickinson’s early style shows the strong influence of Barrett Browning, Scottish poet Robert Browning, and English poets John Keats and George Herbert. In the early stages of her career, Dickinson’s handwritten lyrics imitated the formalities of print, and her poetic techniques were conventional, but she later began to attend to the visual aspects of her work. For example, she arranged and broke lines of verse in highly unusual ways to underscore meaning and she created extravagantly shaped letters of the alphabet to emphasize or play with a poem’s sense.

Visuality, Readability, and Materiality :: Visual Rhetoric Essays

My intention here is to acknowledge two problems that I believe all scholars of "the visible" will encounter at some point in their work. Both showed up early in my research on commemorative artworks, but I suspect that they crash everyone's party at some point. I have no "solution" to these problems, but I believe they should, actually must, be addressed in work on visual rhetoric. The first, "readability," is both a practical and theoretical problem having to do with the possibilities of interpretation in visual culture. The second, which I'll simply label "materiality" for the moment, has a presence in numerous arenas beyond the study of visual culture, but remains nearly unaddressed and nearly unacknowledged in rhetorical work on visual images. The first party crasher, "readability," probably makes its presence felt in all of our venues at least occasionally, but it haunts our work all the time. At the simplest and most practical level, readability is a hermeneutic problem. But it is a special problem of interpretation, not just the "same old" questions that come up in any work involving the production of signs and meaning. We try very hard to reduce the special problem to the same old problems, as evidenced by terms like visual, media, and computer "literacy." The question is this: What makes us so confident that our "readings" of visual signs are legitimate or defensible? Okay, that does sound a whole lot like the "same old" hermeneutic questions, but I don't believe it is the same in the case of visual rhetoric as in spoken or written discourse. Or at least, it doesn't seem the same, given the degree of skepticism registered by readers and students about interpretations of visual signs. Leaving aside for a moment the pos sibility that my interpretations just aren't very good and that that's what's provoking this response, our own colleagues and my students seem to pose far more and greater challenges to such interpretations than they do to those of a speech or a written document. For them, apparently, even in the wake of deconstruction, natural language seems safer, easier, and more stable in its capacity of meaning generation than does the visual image. I wonder why that is the case, and particularly so in a culture in which "seeing is believing" and a "picture is worth a thousand words." It is possible, of course, that this is an idiosyncratic problem, but I doubt it.

African-American Lynch Mob Essay

Author David Horowitz has written an article called African-American Lynch Mob. In the article Mr. Horowitz is expressing his frustration with the way African –American civil rights leaders, namely Reverend Jesse Jackson and Al Sharpton are inciting a lynch mob mentality in regards to the death of Trayvon Martin. Trayvon Martin, who was a 17 year old African-American male, was shot to death by George Zimmerman who happens to be Hispanic. Mr. Horowitz believes that the lynch mob racist, Reverend Jesse Jackson and Al Sharpton are leading the way for the African-American community to insinuate that George Zimmerman is a racist without any facts. First I take issue with Mr. Horowitz fallacy calling Reverend Jesse Jackson and Al Sharpton racist. Is it racist for an individual or group to stand up and fight against inequality and injustices? For many decades Reverend Jackson and Reverend Sharpton have helped those African-Americans who could not help themselves when the odds were stacked against them; providing a strong voice for the law and lawmakers to listen to, when the voices of the African-American citizens were not heard. Doing this does not make one a racist. As mentioned previously, Mr. Horowitz states that Mr. Zimmerman is being labeled a racist without any facts; this is a fallacy and not exactly true. Recently audio has been discovered that has Mr. Zimmerman’s making racial slurs, along with eyewitnesses stating that they personally heard him making racial slurs. The impending investigation will prove whether Mr. Zimmerman is a racist or not; however even in this early stage, investigator will have enough reasons to not rule out the cause of death by race crime. Mr. Horowitz belief that the evidence is irrelevant to the so call lynch mob is unfounded. The African-American protesters are only protesting because they believe there is enough evidence to warrant an arrest of Mr. Zimmerman. However, instead of being arrest Mr. Zimmerman is walking free. Mr. Horowitz calls the display of racial outrage over this case a national disgrace, and I disagree with that statement. The display of racial outrage over this case is not a national disgrace; the fact that African-Americans still have to protest because of injustice is a national disgrace. As I concluded the article it was pretty evident that Mr. Horowitz view point was a bit slighted. It seems to me that the views he has taken are based on his dislike for Reverend Jesse Jackson and Al Sharpton, and their way of obtaining justice for those who they lead and represent. Mr. Horowitz dislike for both of the reverends probably goes a long way back, and because of this, any point that he makes in regards to these two reverends should be taken with a grain of salt.

Methods for Measuring National Income

We have so far been concerned with microeconomic aspects of managerial economics. This chapter onwards, we will deal with macroeconomic aspects of managerial economics. The major aspects of macroeconomics that are generally used in business analysis, especially in analyzing and understanding business environment of the country include (i) the level and trends in national income, (ii) factors determining national income, (iii) factors and forces leading to business cycles, (iv) the trend in general lend of price, especially inflation, (v) international economic aspects, and (vi) government policies, especially fiscal and monetary policies.In this chapter, we will discuss the meaning and methods of measuring national income and the methods of measuring national income in India.10. 1 UNIT OBJECTIVESTo define national income and its importance To discuss various methods of measuring national income To describe the methods used in India for measuring national income To show the growth and trends in national income of India.10. 2 DEFINITION OF NATIONAL INCOMENational income is the final outcome of all economic activities of a nation valued in terms of money. National income is the most important macroeconomic variable and determinant of the business level and environment of a country. The level of national income determines the level of aggregate demand for goods and services. Its distribution pattern determines the pattern of demand for goods and services, i. e. , how much of which good is demanded. The trend in national income determines the trends in aggregate demand, i. e. , the demand for the goods and services, and also the business prospects. Therefore, business decision makers need to keep in mind these aspects of the national income, especially those having long-run implications.National income or a relevant component of it is an indispensable variable considered in demand forecasting. Conceptually, national income is the money value of the end result of all economic activities of the nation. Economic activities generate a large number of goods and services, and make net addition to the national stock of capital. These together constitute the national income of a ‘closed economy’—an economy which has no economic transactions with the rest of the world. In an ‘open economy’, national income includes also the net results of its transactions with the rest of the world (i. e.  , exports less imports).Economic activities should be distinguished from the non-economic activities from a national point of view. Broadly speaking, economic activities include all human activities which create goods and services that can be valued at market price. Economic activities include production by farmers (whether for household consumption or for market), production by firms in the industrial sector, production of goods and services by the government enterprises, and services produced by business intermediaries (wholesaler s and retailers), banks and other financial organizations, universities, colleges and  hospitals, etc.On the other hand, non-economic activities are those which produce goods and services that do not have any economic value. Non-economic activities include spiritual, psychological, social and political services. The non-economic category of activities also includes hobbies, service to self, services of housewives, services of members of family to other members and exchange of mutual services between neighbours. We have defined national income from the angle of product flows. The same can be defined in terms of money flows.While economic activities generate flow of goods and services, on the one hand, they generate money flows, on the other, in the form of factor payments—wages, interest, rent, profits, and earnings of self-employed. Thus, national income may also be obtained by adding the factor earnings and adjusting the sum for indirect taxes and subsidies. The national i ncome thus obtained is known as national income at factor cost. It is related to money income flows. The concept of national income is linked to the society as a whole. It differs fundamentally from the concept of private income.Conceptually, national income refers to the money value of the entire final goods and services resulting from all economic activities of the country. This is not true of private income. Also from the calculation point of view, there are certain receipts of money or of services and goods that are not ordinarily included in private incomes but are included in the national incomes, and vice versa. National income includes, for example, employer's contribution to the social security and welfare funds for the benefit of employees, profits of public enterprises, and services of owner occupied houses.But it excludes the interest on war-loans, social security benefits and pensions. There items are, however, included in the private incomes. The national income is, th erefore, not merely an aggregation of the private incomes. One can however obtain an estimate of national income by summing up the private incomes after making necessary adjustments for the items excluded from the national income.10. 3 MEASURES OF NATIONAL INCOME10. 3. 1 Gross National Product (GNP)Of the various measures of national income used in national income analysis, GNP is the most important and widely used measure of national income. It is the most comprehensive measure of the nation’s productive activities. The GNP is defined as the value of all final goods and services produced during a specific period, usually one year, plus incomes earned abroad by the nationals minus incomes earned locally by the foreigners. The GNP so defined is identical to the concept of gross national income (GNI). Thus, GNP = GNI. The difference between the two is only of procedural nature.While GNP is estimated on the basis of product-flows, the GNI is estimated on the basis of money incom e flows, (i. e. , wages, profits, rent, interest, etc. ).NOTES 10. 3. 2 Gross Domestic Product (GDP)The Gross Domestic Product (GDP) is defined as the market value of all final goods and services produced in the domestic economy during a period of one year, plus income earned locally by the foreigners minus incomes earned abroad by the nationals. The concept of GDP is similar to that of GNP with a significant procedural difference.In case of GNP the incomes earned by the nationals in foreign countries are added and incomes earned locally by the foreigners are deducted from the market value of domestically produced goods and services. In case of GDP, the process is reverse – incomes earned locally by foreigners are added and incomes earned abroad by the nationals are deducted from the total value of domestically produced goods and services.10. 3. 3 Net National Product (NNP)NNP is defined as GNP less depreciation, i. e. , NNP = GNP – Depreciation Depreciation is that pa rt of total productive assets which is used to  replace the capital worn out in the process of creating GNP. Briefly speaking, in the process of producing goods and services (including capital goods), a part of total stock of capital is used up. ‘Depreciation’ is the term used to denote the worn out or used up capital. An estimated value of depreciation is deducted from the GNP to arrive at NNP. The NNP, as defined above, gives the measure of net output available for consumption and investment by the society (including consumers, producers and the government). NNP is the real measure of the national income.NNP = NNI (net national income). In other words, NNP is the same as the national income at factor cost. It should be noted that NNP is measured at market prices including direct taxes. Indirect taxes are, however, not a point of actual cost of production. Therefore, to obtain real national income, indirect taxes are deducted from the NNP. Thus, NNP–indirect t axes = National Income.10. 3. 4 National Income:Some Accounting Relationships (a) Accounting Indentities at Market Price GNP ? GNI (Gross National Income) GDP ?

(1) The national economy is considered as an aggregate of producing units combining different sectors such as agriculture, mining, manufacturing, trade and commerce, etc.(2) The whole national economy is viewed as a combination of individuals and households owning different kinds of factors of production which they use themselves or sell factor-services to make their livelihood. (3) The national economy may also be viewed as a collection of consuming, saving and investing units (individuals, households and government). Following these notions of a national economy, national income may be measured by three different corresponding methods: (1) Net product method—when the entire national economy is considered as an aggregate of producing units;(2) Factor-income method—when national economy is considered as combination of factor-owners and users; (3) Expenditure method—when national econ omy is viewed as a collection of spending units. The procedures which are followed in measuring the national income in a closed economy—an economy which has no economic transactions with the rest of the world—are briefly described here. The measurement of national income in an open economy and adjustment with regard to income from abroad will be discussed subsequently. 10. 4. 1 Net Output or Value-Added Method The net output method is also called the value added method.In its standard form, this method consists of three stages: â€Å"(i) estimating the gross value of domestic output in the various branches of production; (ii) determining the cost of material and services used and also the depreciation of physical assets; and (iii) deducting these costs and depreciation from gross value to obtain the net value of domestic output†¦Ã¢â‚¬ . The net value of domestic product thus obtained is often called the value added or income product which is equal to the sum of wages, salaries, supplementary labour incomes, interest, profits, and net rent paid or accrued. Let us now describe the stages (i) and (ii) in some detail.Measuring Gross Value. For measuring the gross value of domestic product, output is classified under various categories on the basis of the nature of activities from which they originate. The output classification varies from country to country depending on (i) the nature of domestic activities; (ii) their significance in aggregate economic activities, and (iii) availability of requisite data. For example, in the US, about seventy-one divisions and subdivisions are used to classify the national output; in Canada and the Netherlands, classification ranges from a dozen to a score; and in Russia, only half a dozen divisions are used.According to the CSO publication, fifteen sub-categories are currently used in India. 300 Self-Instructional Material After the output is classified under the various categories, the value of gross output is computed in two alternative ways: (i) by multiplying the output of each category of sector by their respective market price and adding them together, or (ii) by collective data about the gross sales and changes in inventories from the account of the manufacturing enterprises and computing the value of GDP on the basis thereof.If there are gaps in data, some estimates are made thereof and gaps are filled. Estimating Cost of Production. The next step in estimating the net national product is to estimate the cost of production including depreciation. Estimating cost of production is, however, a relatively more complicated and difficult task because of nonavailability of adequate and requisite data. Much more difficult is the task of estimating depreciation since it involves both conceptual and statistical problems.For this reason, many countries adopt factor-income method for estimating their national income. However, countries adopting net-product method find some ways and means t o calculate the deductible cost. The costs are estimated either in absolute terms (where input data are adequately available) or as an overall ratio of input to the total output. The general practice in estimating depreciation is to follow the usual business practice of depreciation accounting. Traditionally, depreciation is calculated at some percentage of capital, permissible under the tax-laws.In some estimates of national income, the estimators have deviated from the traditional practice and have instead estimated depreciation as some ratio of the current output of final goods. Following a suitable method, deductible costs including depreciation are estimated for each sector. The cost estimates are then deducted from the sectoral gross output to obtain the net sectoral products. The net sectoral products are then added together. The total thus obtained is taken to be the measure of net national products or national income by net product method.10. 4. 2 Factor-Income MethodThis m ethod is also known as income method and factor-share method. Under this method, the national income is calculated by adding up all the â€Å"incomes accruing to the basic factors of production used in producing the national product†. Factors of production are conventionally classified as land, labour, capital and organization. Accordingly, the national income equals the sum of the corresponding factor earning. Thus, National income = Rent + Wages + Interest + ProfitHowever, in a modern economy, it is conceptually very difficult to make a distinction between earnings from land and capital, on the one hand, and between the earnings from ordinary labour and entrepreneurial functions, on the other. For the purpose of estimating national income, therefore, factors of production are broadly grouped as labour and capital. Accordingly, national income is supposed to originate from two primary factors, viz. , labour and capital. In some activities, however, labour and capital are joi ntly supplied and it is difficult to separate the labour and capital contents from the total earnings of the supplier.Such incomes are termed as mixed incomes. Thus, the total factor-incomes are grouped under three categories: (i) labour incomes; (ii) capital incomes; and (iii) mixed incomes. Labour Incomes. Labour incomes included in the national income have three components: (a) wages and salaries paid to the residents of the country including bonus and commission, and social security payments; (b) supplementary labour incomes including employer’s contribution to social security and employee’s welfare funds, and direct pension payments to retired employees2; (c) supplementary labour incomes in kind, e.  g. , free health and education, food and clothing, and accommodation, etc.Compensations in kind in the form of domestic servants and such other free-of-cost services provided to the employees are included in labour income. War bonuses, pensions, service grants are n ot included in labour income as they are regarded as ‘transfer payments’. Certain other categories of income, e. g. , incomes from incidental jobs, gratuities, tips etc. , are ignored for lack of data.Capital Incomes. capital earnings:NOTESAccording to Studenski, capital incomes include the following (a) dividends excluding inter-corporate dividends; (b) undistributed before-tax profits of corporations; (c) interest on bonds, mortgages, and saving deposits (excluding interests on war bonds, and on consumer-credit); (d) interest earned by insurance companies and credited to the insurance policy reserves; (e) net interest paid out by commercial banks; (f) net rents from land, buildings, etc. , including imputed net rents on owneroccupied dwellings; (g) royalties; and (h) profits of government enterprises.The data for the first two items are obtained mostly from the firms' accounts submitted for taxation purposes. But the definition of profit for national accounting purpos es differs from that employed by taxation authorities. Some adjustments in the income tax data become, therefore, necessary. The data adjustments generally pertain to (i) excessive allowance of depreciation made by the firms; (ii) elimination of capital gains and losses since these do not reflect the changes in current income; and (iii) elimination of under or over-valuation of inventories on book-value.Mixed Income. Mixed incomes include earnings from (a) farming enterprises, (b) sole proprietorship (not included under profit or capital income); and (c) other professions, e. g. , legal and medical practices, consultancy services, trading and transporting etc. This category also includes the incomes of those who earn their living through various sources as wages, rent on own property, interest on own capital, etc. All the three kinds of incomes, viz. , labour incomes, capital incomes and mixed incomes added together give the measure of national income by factor-income method.10. 4. 3 Expenditure MethodThe expenditure method, also known as final product method, measures national income at the final expenditure stages. In estimating the total national expenditure, any of the two following methods are followed: first, all the money expenditures at market price are computed and added up together, and second, the value of all the products finally disposed of are computed and added up, to arrive at the total national expenditure.The items of expenditure which are taken into account under the first method are (a) private consumption expenditure; (b) direct tax payments; (c) payments to the non-profitmaking institutions and charitable organizations like schools, hospitals, orphanages, etc. ; and (d) private savings. Under the second method, the following items are considered: (a) private consumer goods and services; (b) private investment goods; (c) public goods and services; and (d) net investment abroad. The second method is more extensively used because the data re quired in this method can be collected with greater ease and accuracy.Treatment of Net Income from Abroad.We have so far discussed methods of measuring national income of a ‘closed economy’. But most economies are open in the sense that they carry out foreign trade in goods and services and financial transactions with the rest of the world. In the process, some nations get net income through foreign trade while some lose their income to foreigners. The net earnings or loss in foreign trade affects the national income. In measuring the national income, therefore, the net  result of external transactions are adjusted to the total.Net incomes from abroad are added to, and net losses to the foreigners are deducted from the total national income arrived at through any of the above three methods. Briefly, speaking, all exports of merchandise and of services like shipping, insurance, banking, tourism, and gifts are added to the national income. And, all the imports of the co rresponding items are deducted from the value of national output to arrive at the approximate measure of national income. To this is added the net income from foreign investment.These adjustments for international transactions are based on the international balance of payments of the nations.10. 5 CHOICE OF METHODSAs discussed above, there are three standard methods of measuring the national income, viz. , net product (or value added) method, factor-income or factor cost method and expenditure method. All the three methods would give the same measure of national income, provided requisite data for each method is adequately available. Therefore, any of the three methods may be adopted to measure the national income.But all the three methods are not suitable for all the economies simply for non-availability of necessary data and for all purposes. Hence, the question of choice of method arises. The two main considerations on the basis of which a particular method is chosen are: (i) the purpose of national income analysis, and (ii) availability of necessary data. If the objective is to analyse the net output or value added, the net output method is more suitable. In case the objective is to analyse the factor-income distribution, the suitable method for measuring national income is the income method.If the objective at hand is to find out the expenditure pattern of the national income, the expenditure or final products method should be applied. However, availability of adequate and appropriate data is a relatively more important consideration is selecting a method of estimating national income. Nevertheless, the most common method is the net product method because: (i) this method requires classification of the economic activities and output thereof which is much easier than to classify income or expenditure; and (ii) the most common practice is to collect and organize the national income data by the division of economic activities.Briefly speaking, the easy avail ability of data on economic activities is the main reason for the popularity of the output method. It should be however borne in mind that no single method can give an accurate measure of national income since the statistical system of no country provides the total data requirements for a particular method. The usual practice is, therefore, to combine two or more methods to measure the national income. The combination of methods again depends on the nature of data required and sectoral break-up of the available data.10. 6 MEASUREMENT OF NATIONAL INCOME IN INDIACheck Your Progress In India, a systematic measurement of national income was first attempted in 1949. Earlier, many attempts were made by some individuals and institutions. The earliest estimate of India’s national income was made by Dadabhai Naoroji in 1867–68. Since then many attempts were made, mostly by the economists and the government authorities, to estimate India’s national income3. These estimate s differ in coverage, concepts and methodology and are not comparable.Besides, earlier estimates were mostly for one year, only some estimates covered a period of 3 to 4 years. It was therefore not possible to construct a consistent series of national income and assess the performance of the economy over a period of time. 5. What are the methods of measuring national income? 6. What is value-added method? 7. What is factor-income method of measuring national income? 8. How is income from abroad adjusted in national income?In 1949, A National Income Committee (NIC) was appointed with P. C. Mahalanobis as its Chairman, and D. R. Gadgil and V. K. R. V. Rao as members. The NIC not only highlighted the limitations of the statistical system of that time but also suggested ways and means to improve data collection systems. On the recommendation of the Committee, the Directorate of National Sample Survey was set up to collect additional data required for estimating national income. Besides, the NIC estimated the country’s national income for the period from 1948–49 to 1950–52.In its estimates, the NIC also provided the methodology for estimating national income, which was followed till 1967. In 1967, the task of estimating national income was given to the Central Statistical Organization (CSO). Till 1967, the CSO had followed the methodology laid down by the NIC. Thereafter, the CSO adopted a relatively improved methodology and procedure which had become possible due to increased availability of data. The improvements pertain mainly to the industrial classification of the activities. The CSO publishes its estimates in its publication, Estimates of National Income.Methodology used in India Currently, net output and factor income methods are used by the CSO to estimate the national income of the country. The output method is used for agriculture and manufacturing sectors, i. e. , the commodity producing sectors. For these sectors, the value added me thod is adopted. Income method is used for the service sectors including trade, commerce, transport and government services. In its conventional series of national income statistics from 1950-51 to 1966-67, the CSO had categorized the income in 13 sectors.But, in the revised series, it had adopted the following 15 break-ups of the national economy for estimating the national income; (i) Agriculture; (ii) Forestry and logging; (iii) Fishing; (iv) Mining and quarrying; (v) Large-scale manufacturing; (vi) Small-scale manufacturing; (vii) Construction; (viii) Electricity, gas and water supply; (ix) Transport and communication; (xii) Real estate and dwellings; (xiii) Public Administration and Defence; (xiv) Other services; and (xv) External transactions. The national income is estimated at both constant and current prices. 10.7 SUMMARY National income is the market value of all final goods and services produced in a country over a period of time, generally one year. In general, there are three important measures of national income, viz. , (i) GNP, (ii) GDP, and (iii) NNP. In measuring GNP, income earned abroad by the nationals is added and income earned by foreigners in the country is subtracted from national income estimates; on the contrary, a reverse process is used in estimating GDP. NNP is defined as GNP–Depreciation. Depreciation equals the loss of national capital in the process of production.There are three methods of measuring national income: (i) Value-added method, (ii) factor-income method, and (iii) expenditure method. The choice of method depends on the availability of data required for estimating national income. Often two or all the three methods are combined to estimate national income. In India, an organisation called CSO estimates the national income. It uses net output and factor income method for estimating national income. 304 Self-Instructional Material10. 8 ANSWERS TO ‘CHECK YOUR PROGRESS’1.National income is defined as t he market value of all final goods and services produced during a period of time, usually one year.2. In general, three measures of national income are used in economic and business anaylsis: (i) GNP, (ii) GDP, and (iii) NNP.3. The difference between GNP and GDP lies in the treatment of income earned abroad by nationals and income earned by foreigner in the domestic economy. In measuring GNP, income abroad by nationals is added and income earned by foreigners in the country is deducted from the value estimated. In case of GDP, a reverse process is used.4. NNP means GNP less depreciation, i. e. , the value of national capital lost in the process national production.5. There are three methods of measuring national income: (i) net product or value added method, (ii) factor income method, and (iii) expenditure method.6. Under value-added method, first gross value of national product is estimated. Then costs of material and services also depreciation are estimated. These costs are deduct ed from the gross value to arrive at national income.7. In general, factor income method follows the principle that national income = wages + rent + interest + profit. For estimating national income, however, factor incomes are classified as (i) labour income, (ii) capital income, and (iii) mixed income.8. The adjustment of income earned abroad depends on GNP and GDP estimation. In case of GNP, income earned abroad by the citizens of a country is added to the gross value. But in case of GDP, this is deducted from the gross value.10. 9 EXERCISES AND QUESTIONS1.
