Explain the differences between national income or gross domestic Essay

Explain the differences between national income or gross domestic product and what the state of bhutan in the himalayas calls gr - Essay Example More recently the King of Bhutan has promoted a policy of Gross National Happiness (GNH) in opposition to GDP, arguing that the latter did not reflect the important intangible aspects of society and culture such as religious belief, harmony with nature, spiritual peace, and transcendent wisdom. In using GDP only as a measure of national worth and as a guide for planning risks the deterioration of these important intangible aspects globally, and this is most harshly reflected in the destruction of indigenous cultures with philosophical foundations and beliefs different from Western capitalism. II. National Income & GDP Institutions such as the World Bank, IMF, and UN agencies frequently use GDP statistics to determine international aid, finance for development projects, and in the calculation of the distribution of wealth within a society for analysis. These records are drawn from tax accounts primarily as recorded income, leading to the question of differences in accounting standards between nations and the variance of business standards between cultures. Yet, a larger question has developed as to whether GDP as calculated includes the subtle economic and social factors that are important to community welfare. â€Å"Simon Kuznets is best known for his studies of national income and its components. Prior to World War I, measures of GNP were rough guesses, at best. No government agency collected data to compute GNP, and no private economic researcher did so systematically, either. Kuznets changed all that. With work that began in the 1930s and stretched over decades, Kuznets computed national income back to 1869. He broke it down by industry, by final product, and by use. He also measured the distribution of income between rich and poor.† (Econlib, 2011) GDP provides a portrait of the economic activity of a nation by measuring the sum of all economic activity within the sovereign during a given time frame, generally annually. Weight is given to each sector by the total amount of commercial activity involved, but this does not inherently coincide with the hierarchy of values within a society. Instead, it promotes the economic and commercial criteria to the determinant force of national development by defining material prosperity, ever increasing, as the key to a higher standard of living. While in most instances this correlation of economic activity does reflect advanced technological development, improvements in medicine, architecture, public utilities, and the comfort level of society, some critics claim it is not complete or balanced in reflecting the overall values of a culture empirically. Whether or not this can be done is reflected in the debate around Gross National Happiness (GNH), a term instituted by the Bhutanese King Jigme Singye Wangchuck in his coronation address in 1972. III. Gross National Happiness Gross National Happiness is developed from a Buddhist view of the interconnectedness of all life and the need for renunc iation of selfishness and ego in order to cultivate enlightenment. The Buddha taught an Eightfold Path that included interrelated tenets on awareness, morality, behavior, etc. intended to bring about the perfection

Final part - Essay Example My 1st day at the organization began with the formal signing of wavier forms to indicate that I was indeed working there. My supervisor then enlightened me on the tools that were available as well as the duties that I would carry out during the day. My first role was helping him on putting up frames for a house that had been set up in the locality. This involved putting up exterior wood panels so as to cover the already put up frames by nailing them together. Through combined efforts, we were also able to put up ladder blocking in the walls. I also joined another team of workers at the construction site and helped them the top wooden stud of the house in its appropriate place. On the 2nd day, my supervisor assigned me and other volunteers to work on putting up the roof. I assisted in laying of shingles as a base set up for the roof. There was a roofing professional on site to guide on how to properly roof the house in order to avoid any leakages in times of rain. He guided us through proper alignment and nailing of tar papers as well as layering of the shingles in their proper places. We were then required to install the aluminum roof side covers, a process that required effective teamwork to ensure that each nail was properly nailed in its rightful place. Afterwards, we were required to go round the house confirming that the wall panels were all nailed down properly. I was able to identify and rectify a few of errors all by myself by applying what I had previously learnt. In the course of my volunteer ship, I was able to gain 1st hand experience of what I had orally learnt at school. The basis safety guidelines while constructing a house made more sense now that I had carried the out practically. The idea of teamwork during the construction of a house made more sense to me at that time than when it was being taught in class. I was also able to analyze the principles of construction that I had been taught earlier. This was in

Data structures and algorithms for social media Essay

Data structures and algorithms for social media - Essay Example This treatise discusses how the choice of data structures and algorithms affect social media. The paper also focuses on the differences in security procedures when it comes to large data sets as found in social media sites as compared to simpler and Java-driven websites. Social media are a group of websites that aid in social interaction, and consist of voluminous databases. In understanding data structures, one should take into account that they mostly define the memory mechanisms. In a computer, data is conveyed in chunks from the Random Access Memory (RAM) to the hard disk. The running time of this transfer is determined by the blocks/chunks. Data structures enhance efficiency in computing. The more powerful a computer is enables it to handle more complex applications, which lead to more complex calculations (Bender & Kuszmaul, 2014). The choices applied in the selection of data structures and algorithms determine whether a particular calculation will be carried out in many days or in just a few seconds. In social media, the information is stored in large database; hence, computations that result in searching of different information need to be performed at a very fast rate. This calls for keen choice of data structures and algorithms. In enhancing efficiency, a given solution will be termed efficient once it solves the problems assigned to it within the confines of the resource constraints (Shaffer, 2014). In deciding the data structure to use in a social media site, some of the steps to consider include; an analysis of the problem for determination of the applicable resource constrains, determination of the operation to be supported against the resource constrains, and selection of the most appropriate data structure for the given problem. In selecting a data structure, it is always good to consider the cost of the solution, which is a factor of the resources used,

The Great Depression in Canada Essay Example | Topics and Well Written Essays - 1500 words

The Great Depression in Canada - Essay Example One of the examples of a depression is often regarded to be the great depression witnessed by Canada. The period of depression was recorded to instigate during the summer of 1929 and extended till the spring of 1933. For the Canadian citizens, the depression period of the 1930s is still considered to be the most devastating decade of the century2. The major cause for this was the crash in the stock market, which is often considered to be the consequence of the wheat crop crash in Canada. With due consideration to the notion of a depression and its emergence in the Canadian economy, the main objective of this paper will be to understand the major causes of the economic turmoil and also to describe the aftermath of the depression. A brief description of the total scenario of Canada in the historical context of the great depression will be presented in this paper. Historical Background The great depression of Canada existed during the 1930s as an era of economic poverty. The reasons for this depression in Canada can be related with various economic factors such as economic dependency, poverty, and unemployment among others. The period of depression initially was recorded in the year 1929, when United States discontinued purchasing goods from the Canadian market. This resulted in lockouts in many of the Canadian industries and thus contributed to the financial crisis. A huge number of Canadians became jobless and homeless lacking the basic amenities required to lead a healthy life. Even after getting a job, the Canadians were often paid at extremely low rates, which were not enough to fulfill their basic needs. The remaining unemployed Canadians used to move across the country in search of jobs and thus increased the liabilities of the government through inbound migration trends3. In Canada, the financial crisis was first observed in 1928 after the wheat crop crash had emerged resulting in the crash of the Wall Street Stock Market that later took the form of the gr eat depression. One of the major causes of the depression in Canada was the over-production and over-expansion in the industrial sectors. During the 1920s, almost every industry in Canada was expanding and many new industries came into existence. As a result of this, the factory owners generally used to pile up huge stocks of goods. Consequently, after the crash of the stock market, these owners panicked and in order to slow down the production they laid off a huge number of workers. This resulted in a huge unemployment problem within the economy, which fuelled up a financial crisis in Canada. Therefore, the sale also went down causing an economic misbalance4. Furthermore, the Canadian economy remained entirely dependent upon a few primary products such as wheat, minerals and fish. Accordingly, the economy could not bear the loss from financial crisis as the demand for these goods went down after the unemployment problem. The economy of Canada was also related closely with the econo my of the United States. Hence, with the emergence of a crisis within the American economy, the economic conditions of Canada also deterioted by a considerable extent. All through the 1920s, credit purchase became more and more favored in Canada. The added interest payments with the principle amount made many families go under huge debts4. Another very popular trend in the Canadian market at

The Business Environment Essay Example | Topics and Well Written Essays - 1000 words - 1

The Business Environment - Essay Example Businesses also aid in settling economic requirement of more than 70% of Kenyan citizens through the provision of employment opportunities. Through these employments, the government is able to involve the large population in the day to day national economic activities. Business organizations are able to produce significant quantities of goods at reduced cost. The economies of the scale are achieved; business organizations incur lower costs per unit of output because they operate on a large scale thus lower price of their products (Wang, 2009). In fact, large-scale account for over 60 per cent of all the private sector’s production. A substantial output in the gross domestic product (GDP) is thus achieved nationally due to this high percentage. Business has also enhanced economic development through encouraging competitive innovation. It is through competitive innovation that the nature of products and services Improves on a daily basis. A good example is the banking industries , initially they had only over the counter transaction, later came the automated teller machines and now mobile banking that are developments that were brought about by innovation. It is also through this that the consumers get to use the up to standard goods and services. Businesses also give chances to entrepreneurship which greatly help in the development of the economy (Haraf & Willett, 1990). Both for-profit and nonprofit profit has their share of contribution to the economy. The for-profit organizations participate actively through payment of revenues, employment creation, service provision, and production of goods and services that to the public. On the other hand, nonprofit organizations might be exempted from tax payment, but still do play a significant role in a country’s economy through involvement in activities like, provision of education, health services, voluntary provision of professional services like counseling, community services and quite a variety of serv ices essential to the sustenance of the economy. Nonprofit organizations always have it rough when it comes to capital acquisition. This is clearly portrayed by their depend on donors, well wisher and in some cases grants from the government. On the other hand, the for-profit organizations always have more option ranging from selling shares to investors, liquidating of assets, and credit from banks and profit from a business transaction. Another difference crop up when we view how the assets are handled. In the nonprofit organizations, the assets are considered nobody’s property, thus in the case of dissolution, the assets might be considered for donation to another organization of the same nature. Unlike the non-profit organizations, the for-profit organizations have their assets owned by the owners of the business (Doole & Lowe, 2008). Monetary policy can be described as the procedure through which a country control the supply of its currency while fiscal policy can be desc ribed as the use of taxes and expenditures by the government to manipulate the economy. There are majorly two forms of monetary policy programs: expansionary (easy) monetary policy and restrictive monetary policy (Wang, 2009). The expansionary monetary policy lowers the domestic currency exchange rate thus weakening the current account and ultimately improving the financial account. Vise versa
