Drug Use And Abuse Is A Old As Mankind Itself - 1585 Words

Drug use and abuse is as old as mankind itself. Human beings have always had a desire to eat or drink substances that make them feel relaxed, stimulated, or euphoric. Humans have used drugs of one sort or another for thousands of years. Wine was used at least from the time of the early Egyptians; narcotics from 4000 B.C.; and medicinal use of marijuana has been dated to 2737 BC in China. As time went by, home remedies were discovered and used to alleviate aches, pains and other ailments. Most of these preparations were herbs, roots, mushrooms or fungi. They had to be eaten, drunk, rubbed on the skin, or inhaled to achieve the desired effect. One of the oldest records of such medicinal recommendations is found in the writings of the†¦show more content†¦The most fascinating of these substances are sacred mushrooms, used in religious ceremonies to induce altered states of mind, not just drunkenness. These were all naturally occurring substances. No refinement had occurred, and isolation of specific compounds (drugs) had not taken place. As the centuries unrolled and new civilizations appeared, cultural, artistic, and medical developments shifted toward the new centers of power. A reversal of the traditional search for botanical drugs occurred in Greece in the fourth century BC, when Hippocrates (estimated dates, 460-377 BC), the Father of Medicine, became interested in inorganic salts as medications. Hippocrates authority lasted throughout the Middle Ages and reminded alchemists and medical experimenters of the potential of inorganic drugs. In fact, a distant descendant of Hippocrates prescriptions was the use of antimony salts in elixirs (alcoholic solutions) advocated by Basilius Valentius in the middle of the 15th century and by the medical alchemist Phillippus Aureolus Paracelsus (born Theophrastus Bombast von Hohenheim, in Switzerland, 1493-1541). South American Indians, especially those in the Peruvian Andes mountains, made several early discoveries of drug-bearing plants. Two of these plants contain alkaloids of worldwide importance that have become modern drugs. They are cocaine and quinine. Cocaine s

Economics and Quantitative Analysis GDP

Questions: 1.Explain why real GDP might be an unreliable indicator of the standard of living.2. Why does unemployment arises and what makes some unemployment unavoidable?3.Consider the following statement: When the average level of prices of goods and services rises, the inflation rate rises? Do you agree or disagree? Explain.4.what is the aggregate demand (AD) curve and why does it slope downwards? Explain5. What is the long run aggregate supply (LRAS) curve and why is it vertical? Why does the short run aggregate supply curve slope upwards? Answers: 1. Real GDP is the measure of the total out produced within the domestic territory of a country within a year that is adjusted to the price changes due to inflation or deflation. An increasing real GDP indicates increased availability of goods and services in the economy and improved purchasing power of consumers. Thus, it is a good indicator of monetary aspect of living standard. However, it does not say anything about quality of life (Boyes and Melvin, 2015). The overall standard of living is not reflected by monetary measures only. Rather, it also reflects changes in living standards due to non-monetary aspects such as education, health, quality of life and goods and services consumed, and others. Therefore, multiple measures affect standard of living but are not considered while calculating real GDP. These measures include household production, unpaid work like taking care of child or elderly, mother taking case of household, volunteer work, community services, parallel economy that is usually hidden to avoid taxes and other regulatory requirements, leisure time, education standard of people, security, quality of environment, health and life expectancy, happiness and political freedom and justice (Boyes and Melvin, 2015). Therefore, rising real GDP does not project an increase in income of all the sections of society. Moreover, if real GDP is rising but health or education or environment quality is declining, then people are not leading good life. Hence, it can be said that real GDP is poor indicator of standard of living. 2. Unemployment can be defined as an occurrence of the uncertainty of work for a person, who is actively looking for the job but unable to find any job (Mctaggart, Findlay and Parkin, 2012). Apart from these people, many people who are not able to work because they are handicapped, disabled, retired, students and discouraged workers. The unemployment rate can be measured by dividing the number of unemployed person to total number of workforce available. The number of unemployed individuals has huge impact on the economic condition and national income of the nation. In the context of economic condition, widespread unemployment in nation can arise due to some reasons that include high growth of population, illiteracy, race system, reservation system and financial crises. Unemployment can be categorized in three different parts that includes Cyclical Unemployment, structural unemployment and frictional unemployment (Mctaggart, Findlay and Parkin, 2012). Cyclical unemployment can arise due to economic condition of the business that includes recession in economic condition. Further, structural unemployment occur due to technological changes in the business that shows that employees skills are obsolete. Frictional unemployment can occur when a person is looking for the job after completing the education, or leaves the job and looking for new job or retirement of the person from full time work. Unemployment is unavoidable due to changing organisational policies and use of different technologies that reduce labor supply, looking for new job for best position and retirement from the work. These factors show that unemployment is unavoidable. 3. When the price of goods and service increases the inflation rate rises. This statement shows the real causes of inflation. In the economy, inflation can be identified as changes in price of goods and service and it is projected as inflation rate (Cencini, 2012). Inflation rate is related with measurement of changes in the price of usually unpreserved goods and service. Inflation can be defined as the situation of frequently increasing price of commodities and actual factors of production. Inflation refers to various consequences that are related with increasing the price of goods and service but it cannot be considered as high price. Inflation rate can increase due to high cost of production because it provide product at high price and high level of demand encourage inflation because high consumption of product affect the price of product. Further, monetary system of the nation is the main cause of inflation. Inflation rate affect economic condition of the nation that includes GDP, FDI, consumption and demand levels. Inflation affects the level of production in the nation that includes supply of the material for production due to expectation of supplier to sell the product at high price to earn high profit and changes in transaction system. Further, inflation encourages speculations and black-marketing that have negative impact on national economy. Inflation also affects government policy, exchange rate, monitory policy and balance of payment in the nation. In the nation, inflation can be controlled by monetary policy that includes controlling the wage, monetary system of nation, increasing tax rate and saving (Taylor, 2011). 4. The aggregate demand curve represents the total quantity of goods and services demanded in the economy at various price levels. Downward sloping demand curve indicates the inverse relationship between the price level and quantity demand of real GDP (Veseth, 2014). This means that aggregate demand increases due to fall in price level. There are three reasons that cause aggregate demand curve to be downward slopping. As per wealth effect, AD curve is drawn under the assumption that supply of money is held constant by the government and the supply of money depicts the economys wealth. If there is rise in price level, wealth of economy declines and in turn reduces the purchasing power of an individual. Moreover, if price decrease purchasing power of money increase buyers become wealthier and capable to purchase more goods than before. As per interest-rate effect, if there is increase price level, the increase demand for fixed supply of money also causes the interest rate to rise. Due to this, spending of buyers that are sensitive to interest rate will decrease (Glanville and Glanville, 2011). In contrast to this, a lower price level reduces the rate of interest which in turn increases spending on investment. Net-export effect explains that if there is increase in price level , foreign made goods becomes cheaper which results in increased imports while the domestic goods becomes expensive for foreign buyers that results in decreased demand for exports. When import increases and export decreases this cause decrease in net exports. Moreover, lower price level shows inverse impact on net exports as compared to high price level. Figure: Aggregate Demand Curve 5. The long-run aggregate supply curve represents the relation between real production and price level for long run. It shows the supply of goods and service at the certain price for the long term. In the long-run, aggregate supply curve is vertical because the resources i.e. labour, technology and capital are assumed to be utilised at their optimal level. Additionally, in the long-run, it is assumed that full employment persists in the economy. Thus, supply of factors of production cannot be increased. If there is change in the price, there will be movement along the curve but quantity will remain the same (Boyes and Melvin, 2015). Moreover, any increase in factors of production will lead to outward shift in the supply curve but the slope of LRAS will remain vertical. Figure: long run aggregate supply curve (Boyes and Melvin, 2015) Short Run Aggregate Supply Curve: Short run aggregate supply curve represents the aggregate price level and has the slope that is upward rather than vertical. In economics, there are three theories that identify about upward slope of short run aggregate supply curve. It includes Sticky price theory, misperception theory, and sticky wage theory that identify about economic changes in the price and supply. Figure: Short run aggregate supply curve (Mankiw, 2014) In the short-run aggregate curve, supply has positive relation with price, which shows that if price level will increase, the supply will be increased. Similarly, if price level will decrease then supply will be decreased (Free, 2010). References Boyes, W. and Melvin, M. (2015) Economics, 10th edn. Boston: Cengage Learning. Cencini, A.

Portrait of a Lady by Alessandro Allori Essay Example

Portrait of a Lady by Alessandro Allori Essay When I first read the instructions for this essay, I was a bit frightened on how I was going to approach this project. At first, my attitude was that museums were boring and uninteresting, although this was my first perspective of museums, my whole mindset had completely switched to the opposite side of the spectrum. At first, when I had walked into the museum, and it was such a smooth calming feel in which I enjoyed, I had walked into the San Diego Museum of Art. I had Stumbled across the oil on panel portrait called â€Å"Portrait of a Lady† by the infamous Italian painter, Alessandro Allori. This beautiful Florentine piece of art was created in 1560. This portrait is a woman who is firmly holding her head high with a gorgeous lace dress and impressive flashy jewels. She is wearing a Florence dress which indicates the time this was created, in the 16th century. She appears to have marble looking skin with confidence a woman should have. The formation overall of this piece of work is quite detailed. First Allori uses more diagonal lines in the portrait, for example, the face, arms, beginning of the dress, stripes at the bottom of the dress and body of the woman. He uses these lines to make the woman appear bigger as well as height. This shows that the artist wanted to make this art very important and straight to the point. He uses curve lines for the width of shoulders, arms crossing, and hairline and width of the dress as well. The shape is an oval for the head and rectangle for the body of the woman, Allawi may have used these two shapes before creating the portrait. The form is an oval for the head of the body and a cylinder for the body. Allawi may have also used these forms before creating this masterpiece as well. Space is very positive and bright for the overall body, contoured by negative space in the background. The negative space is black on the portrait which outlines the ladies body; our eyes are drawn t o her, not the bl We will write a custom essay sample on Portrait of a Lady by Alessandro Allori specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Portrait of a Lady by Alessandro Allori specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Portrait of a Lady by Alessandro Allori specifically for you FOR ONLY $16.38 $13.9/page Hire Writer
