Computer Addiction Essays - Behavioral Addiction, Computer Addiction

Computer Addiction March 2, 2000 There once was a time when the only computers known to the average person were those the military possessed. Eventually, large corporations found many different uses for computers in the business world, and today, computers are as common in numerous households around the globe. People from all age groups are learning to operate computers and anyone who has worked with computers for long periods of time knows that computers can be just as addicting as smoking. Computer addiction can have a number of physical, social, and psychological effects on a person and it is to be taken as seriously as any other addiction that a person is battling. One common physical effect computer addiction can have on a person are back problems. Sitting for so long can take a toll on a person's muscles and can result in poor posture. Poor posture can result in chronic back problems that require the services of a chiropractor. Dry eyes, carpal tunnel syndrome, and vision complications are some eye problems caused by over use of a computer. Migraine headaches are quite common in computer addiction and are linked to the straining of the eyes. Because of the long hours spent engrossed in a computer, addicts often have eating irregularities, such as skipping meals and binge eating. Computer addicts experience sleep disturbances, or changes in sleeping patterns, which are most likely due to late hours on the computer and low blood sugar from eating irregularities. One last effect is the failure to attend to personal hygiene, such as bathing, combing hair and brushing teeth. All of these physical effects can be linked to computer addiction. Social effects of computer addiction include reduced time spent socializing with others. People may begin to feel that their computer is the only relationship that they have the time to focus on. They lose the desire for human contact and communication and in a way they are breaking away from reality. Lacking the desire to make contact with others, means lacking the desire to create new relationships or to build on already existing ones. After a certain amount of time, they lose their conversation skills completely. Within the lives of computer addicts it is their friends and family that suffer the most from this form of alienation. They are often moved to the very bottom of the computer addict's list of priorities. Computer addiction has the power to cause serious social effects and cannot be left untreated. Along with the physical and social effects of computer addiction there are also psychological effects. Some psychological symptoms experienced by computer addicts when they are not at the computer are feelings of depression, emptiness, irritability, distraction and withdrawal. Feelings that are common when addicts are at the computer are a sense of euphoria or well-being. These senses of complete ecstasy and pleasure also causes and inability for people who are addicted to computers to stop the activity. They end up having a constant craving for more time at the computer, and this is where one can identify an addiction. Along with addiction comes a need to cover up their secret and computer addicts often lie to those around them. For example lying to employers, and family members about their hours spent at the computer and also denying they have a problem. This lying a sneaking around eventually results in problems either at school or at work. The psychological effects of computer addiction may not only lead to distraction and emptiness but may also lead to critical depression. When people think of addictions, no one ever thinks of computer addiction to actually be common. In this age of computers, computer addiction will only increase as time passes. More and more people will experience the physical, social, and psychological effects of computer addiction but, thankfully, like other addictions, this condition is treatable.

Selection Decision Making Case Study Example | Topics and Well Written Essays - 1000 words

Selection Decision Making - Case Study Example A selection plan gives an overview of how the job looks like thus making it easy for the recruitment panel to pick the most desirable applicant. It contains key job responsibilities, makes it clear of what must be performed and acts as a guide in selection procedures. The format is as given below. The table above illustrates scores of all the ten applicants. The analysis was based on multiple predictor methods; clinical prediction and rational weighing. However, since clinical prediction and unit weighing produce similar results, it was considered wise to include the unit weighing column. The unit weighing figures were derived from averaging each applicant’s scores in individual assessment methods. Basing on the unit weighing results, tangle wood will consider the highest scores. Therefore, Heckman; 76, Reznor; 73 and Scores; 70 will be the most preferred applicants. The rational weighing results were obtained by assigning a weight to every assessment method and summing up the scores. The assigned weights were biodata; 30%, Applicant exam; 10%, Retail knowledge; 30%, Conscientiousness; 15%, Extraversion; 15%. Biodata and retail knowledge were allocated the largest weights because the job position demands experience from applicants. Applicant exam was assigned the lowest weight mainly because it measures the least important KSAOs required in the managerial position. From the data, Tangle wood will consider Heckman; 76, Reznor; 69, Renoir; 67.5. If tangle wood decides to use multiple hurdle selection as its first stage in identifying the best five applicants, and further apply interviews and resumes to get the top three finalists, the five suitable candidates would be Reznor, Yorn, Greer, Renior and Durvall. This is quite interesting since Heckman who tops in both rational and unit weighing does not appear in the top five when using test scores. Since conscientiousness and extraversion prove the ability and suitability of an applicant to perform and

Service Marketing Management in Ebay Case Study

Service Marketing Management in Ebay - Case Study Example This research will begin with the statement that eBay (www.ebay.com) is managed by EBay Inc., an Internet company based in America. Ebay.com offers an Internet-based service that allows for online auctions, selling and buying of new and second hand products. While the company originally began functioning in US, today it has localized branches in Belgium, Canada, China, France, Germany, India, Italy, Singapore, United Kingdom, Poland, Philippines and Taiwan to name a few. Besides Ebay.com, EBay Inc also owns the sites of PayPal and Skype among its other businesses. Since the site was established in the year 1995, it has become the largest place in the world to buy and sell a range of products to a range of people. In April 2006, eBay also opened its new eBay Express site. This site works like a standard Internet shopping site for consumers from United States. A UK version and then a German version were launched later in the year and offers brand new items sold by pre-vetted sellers. T he company works with the mission to provide a global trading platform where practically anyone can trade anything. The company has a unique offering of an auction-based sales service where retailers or private seller can present their item to purchasers. Demand and supply: The level of demand and supply on eBay is high as there are many people seeking to sell what they do not need for a good deal. Approximately the site has 212 million registered buyers and sellers as of date. A wide range of things like rare items, new products, collectibles and used goods can be found for sale on the site. The site is well known as a good place for comparison shopping as many similar products are listed side by side. Auction-style listings, fixed price formats and Dutch auctions are a few kinds of auctions the site provides for. However there are cases where the required products are not available. Not much can be done in cases where demand exceeds capacity and customers just have to live with th e fact that sellers are not selling the required product. Services marketing integration and management: Customers usually search for products on parameters like price and product features. eBay allows customers to sort similar items based on pricing, making the task of purchasing a relatively easy one. Phone help is offered to select members only (those who sell a minimum of $3000 worth goods per month through the site). Live chat with customer service representatives is however available. Areas where eBay dissatisfies customers include wrong shipping labels and insufficient customer support as all queries are not addressed with the same interest. The blame culture is high at eBay, and though the site issues regular warnings, blogs and advice, many blame the site for wrong transactions. One criticism regards its privacy policy whereby eBay turns its user information to law enforcement agencies often without a subpoena. While no solid proof has been generated for this case, it is a popular rumour, popular enough to be believed by its wide customer base as true. Finally no panel of experts or support system is available to identify whether a particular product is worth the money or not.

Definitions of Property in English Law Essay Example | Topics and Well Written Essays - 750 words

Definitions of Property in English Law - Essay Example For instance, the Law of Property Act 1925 classifies property in terms of real and personal property, rather than defining it1. Therefore, the most common definition of property is derived from the case laws that emphasize the rights owned or enjoyed by a person that owns the property. This is the position in the holding of National Westminster Bank v. Ainsworth, where the House of Lords held that the right to a property must be definable, identifiable by third parties, capable in its assumption by third parties as well as have a certain level of degree of permanence or stability.2 This implies that property entails the idea of possession and control of particular rights by an individual. In England, there property may be defined into either private or public property. However, the common position is that property may be defined into the rights of a person with respect to a thing. In common law, which is practiced in England, this may be rights over real property, which is land, as well as personal property, which refers to the chattels. Within this classification, there may be the real property, which refers to the corporeal hereditaments that are the tangible real property and the incorporeal hereditaments that are intangible. The personal property on the other hand refers to any property that is tangible or intangible but excludes land3. One can only obtain the personal property through possession of a property interest on the property that excludes others. Similarly, the property may be obtained when an owner involuntarily parts possession of it through loss or abandoning it. The person to whom the property is transferred may also obtain it through confusion and accession as well as bailment. A person may also acquire the personal property as a bona fide purchaser for value.

Comparison of Economic Systems: Germany and the UAE

Comparison of Economic Systems: Germany and the UAE Introduction â€Å"Economy is the state of a country or region in terms of the production and consumption of goods and services, and the supply of money†(Oxford Dictionaries 2012). Before profound studying about the mentioned countries one important aspect should be taken into consideration the similarity between these two countries is their critical role in their region, both of those countries has a significant influence on the political and economy climate in their respective regions. Germany is located in Central Europe, south of Denmark, between Poland and the Netherlands. It has a direct access to North and Baltic seas. The countrys total area is 357,022 sq.km and the population around 82 million people. Historically, Germany has evolved couple of unifications and reunifications including the last one in 1990. Excellent infrastructure, location, skilled workforce and moderate wage rate make Germany very attractive for business. Notwithstanding, there are some environmental problems, such as air and water pollution, soil erosion, diminishing biodiversity and shortage of resources. The United Arab Emirates is located on the eastern part of Arabian Peninsula and shares borders with the Kingdom of Saudi Arabia to the south, Oman to the east and sea sharing borders with Qatar. Also, country has a direct access to Persian Gulf and Indian Ocean. The UAEs total area is much smaller, only 83,600 sq. km. The United Arab Emirates thrift and stability is substantiating by its considerable oil wealth that was discovered in 1960th, most of which is concentrated in Abu Dhabi the countrys capital (â€Å"United Arab Emirates profile’ 2012). Although, the UAE will remain be contingent on the oil reserves for many years to come, nevertheless, its level of dependency is gradually declining. The main role in development was taken by Dubai, which has become a regional financial, commercial powerhouse and o one the prime tourism centers of the Gulf Region. Moreover, a strong combination of oil prices, plentiful financial and fiscal resources, political stability, regulator y reforms and infrastructure development will backing the UAEs country risk profile. Germany represents a federal parliamentary, representative republic with a six main political parties, dominated by the Christian Democratic Union, the Christian Social Union of Bavaria and the Social Democratic parties. The head of the government who exercises executive power is a Chancellor Angela Merkel. Nevertheless, due to the fact that Germany is a member of European Union and G8, policies are subordinated with those organizations. As the biggest economy in Europe, Germany contributes 25% of Eurozones GDP. The political structure of the United Arab Emirates is a federation of seven monarchical emirates. His Highness Sheikh Khalifa bin Zayed Al Nahyan is an emir of Abu Dhabi and the President of the country. The federal system of government includes the President, the Prime Minister, the Supreme Council, Crown Princes and Deputy Rulers, the Federal National Council,the Council of Ministers (UAE Government 2012). Although, Germany has the second largest population in Europe, it faces an aging population. This implies some long term problems, such as increase in governmental welfare expenditures, healthcare expenses, pension’s payments and loss in income tax. Nevertheless, countrys immigration policies and laws set up favorable conditions for immigrants, and immigration rate exceeds emigration level. 10% of Germanys population consists of non-native nations, such as Turkish, Greek, Italian, Russian, Polish, Spanish and Serbo-Croatian. According to World Bank, UAE’s locals constitute only 16.5% of the total population. Meanwhile, the number of expatriates increasing over time, Indians accounts the biggest part with a 1.7 million people. Also, most of native representatives tend to work in public sectors, benefiting with a higher salaries, shorter working hours, greater job security, while 98% of private-sector workplaces are occupied by expatriates. As the graphs below represent the population pyramids for compared countries, we can mention the aging population in Germany, as was described previously. Also we pay attention on difference in population composition of those countries. Almost in every age group Germany’s population is somewhat balanced between male and female genders. On the other hand, we can see the drastic difference between male and female composition of United Arab Emirates’ population. Age groups from 20-64 is highly dominated by males; this caused by the fact that most of them are expatriates and they are coming to the country in search of a job, leaving their families in home countries. Source: US Census Bureau, International Data base (IDB) GDP Growth The economy of Germany continues to be based on individual consumption and going to strengthen by further investments, meanwhile next exports is still deterring growth. Germany has been decreased its dependence on exports in recent years. In addition, the Social Democratic Party has successfully pushed for an expenditure increase in infrastructural, educational sectors, as well as pension increase and minimum-wage regulation across all country by 2015. Eurozone’s debt-crisis caused uncertainty on consumers’ confidence and future expectations about their personal finances. Income is continuing to be supported by stable employment and increase in average wages. Also the expected perseverance of historically low interest rates will reinforce investment growth during upcoming years. Cheap mortgages will robust construction industry. Exports will recover during 2014, but the Eurozone crisis and geopolitical conflicts in the Ukraine and the Middle East are limiting scope. Although consecutive economic stabilization in the European Union will permit German exports to strengthen, the spikes in rebound trend during end of 2013 and beginning of 2014 – the natural structure of European debt crisis which in turn will limit the speed and vigour of export recovery. Furthermore, incandesce of Ukrainian situation and possible further escalations of actions in Iraq are incrementing world’s uncertainty and keeps internati onal trade back. The expected growth of the GDP of UAE is 4.3% in current year. Compared to the previous year the GDP growth, the highest after Great Recession, has declined. Economic growth had a strong acceleration in 2013 of 5.2%, but then economy faces some difficulties. Oil GDP expands only at a 1.8% rate this year, following 4.8% in 2013. With average global price of $109 per barrel in 2014, UAE oil output – which concentrated within the Abu Dhabi emirate – is going to reach around 2.7-2.8 million barrels per day. Non-oil sectors of the economy will continue to outrun growth driven by oil extraction. Activity in the non-oil sector has been steadily recovering following the downturn in 2009 and will continue to be the driving force of the economy’s growth momentum in 2014. Non-oil GDP is continuing holding on the same level as in 2013 – approximately 5.4%. The UAE has economy is relatively stable amid the disorder in the region. The key non-oil activities such as tourism, retail, and service help to drive the growth. Manufacturing activities led by aluminium and petrochemical industries is going to strengthen the following years. Also strong economic conditions will benefit both the transport and trade sectors. Real estate and construction sectors also improved along with overall market conditions. Infrastructure and development projects also had an additional motivation with Dubai’s award of next Expo city. A set of regulations implemented by authorities will help against a repeat of a boom cycles in Dubai. All these facts regarding Expo 2020 should provide a platform for a stable growth in tourism, construction, transport and hospitality industries in next 5 years. 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 Germany -0.38% 1.16% 0.68% 3.70% 3.27% 1.08% -5.14% 4.01% 3.33% 6.89% 4.32% UAE 8.80% 9.57% 4.86% 9.84% 3.18% 3.19% -4.80% 1.67% 3.88% 4.37% .. GDP by type of Expenditure According to the expenditure approach of calculation of Gross Domestic Product, it equals to the sum of such components as consumption (C), investment (I), government purchases (G), and net export, i.e. difference between export and import (NX): Y=C+I+G+NX. Germany UAE Gross capital formation (% of GDP) 17.26 22.66 General government final consumption expenditure (% of GDP) 19.29 6.90 Household final consumption expenditure, etc. (% of GDP) 57.53 49.75 Net Export (% of GDP) 5.92 20.68 Inflation UAE consumer inflation surpassed the 2% mark in April for the first time in five years, according to the National Bureau of Statistics. Housing price inflation was relatively continual with 2.6% year on year in May; Dubai’s inflation has lowered to 3.7% compared to 4.9% in April. Real estate has become the main inflation driver in UAE, excelling food price inflation of 2.1%, even as food prices are increasing at 0.9$ rate per month. Consumer inflation is soon averaging 2.2% in 2014. The recovery of housing prices reflects the prolonged downturn in the real estate market. The annual inflation rate is expected to soar up to 3% by the end of 2014. Mildness of world’s commodity prices is going to benefit the inflationary pressures. The United Arab Emirates could face higher problems in their inflation outlook if commodity and food prices go up. 2008 2009 2010 2011 2012 Germany 2.6% 0.3% 1.1% 2.1% 2.0% UAE 12.3% 1.6% 0.9% 0.9% 0.7% Germany’s nationwide inflation should remain at a very kind level between 1% and 2% in near future. Following the consumer prices inflation leaped from a 22-year low of -0.5% in 2009 to around 2.5% in 2011, the economic deceleration caused by the Europe’s debt crisis during 2012 and early 2013 have led to a softening below 1.5% that will remain during 2014. On balance, core inflation should move broadly sideways to around 1.5% during 2014, as a boosting effect from the Germany’s economic recovery is offset by the continuing restraints of the Eurozone debt crisis, also the anticipated downward tendency of oil prices due to global supply factors. Although, monetary policy of the European Central Bank (ECB) will be much lighter than Germany’s economy is demanding. Germans’ traditional disinclines to inflation should limit the extent to which Germany’s inflation will exceed the European average. Also, inflation will be stacked the level ECB considers unproblematic. Also due to pressure on ECB to buy Eurozone’s governments’ bonds and to allow higher inflation rates is enduring upward economic risk within the region. 2007 2008 2009 2010 2011 Germany 96.1 98.6 98.9 100 102.1 UAE 87 97.6 99.1 100 100.9 Human Development Index The Human Development Index summarizes the long-term development of a particular country or region. It includes three basic parameters: living standard, knowledge accessibility and health and longevity. The HDI is primarily based on international data provided by the United Nations Population Division, the United Nations Educational. In year 2013, The United Arab Emirates had a very high HDI value of 0.827— which places the country on 40 out of 187 countries. From the very beginning of its existence as a government, the United Arab Emirates HDI had value increased from 0.640 to 0.827, and soared up for 29.2 percent. This gives us the average increase of about 0.78 percent per year. The Table below reviews the United Arab Emirates progress of the HDI indicator. Between 1980 and 2013, that was achieved by couple of factors: the United Arab Emirates life expectancy at birth increased by 9.2 years, average years of schooling increased by 5.5 years and expected years of studying increased by 4.7 years. On the other hand, the United Arab Emirates GNI per capita has decreased by about 62.2 percent between 1980 and 2013, due to tremendous increase in expatriate population. UAE Germany GNI per capita (2011 PPP$) HDI value GNI per capita (2011 PPP$) HDI value 1980 153,654 0.64 25,588 0.739 1985 139,421 0.686 27,355 0.752 1990 97,141 0.725 31,002 0.782 1995 102,203 0.764 32,643 0.825 2000 103,798 0.797 35,497 0.854 2005 104,668 0.823 37,259 0.887 2010 57,360 0.824 40,542 0.904 2011 56,393 0.824 41,907 0.908 2012 57,095 0.825 42,965 0.911 2013 58,068 0.827 43,049 0.911 The recent Germany’s HDI value is 0.911— which in turns is one of the highest on the globe —positioning the country at 6 out of 187 countries and territories. Taking the same time range as for UAE, 1980 and 2013, Germany’s HDI value increased from 0.739 to 0.911, an increase of 23.3 percent or an average annual increase of about 0.64 percent. This in comparison to UAE is slightly lower. The table reviews Germany’s progress in the HDI index. The increase in HDI is consisting of: Germany’s life expectancy at birth increased by 7.7 years, mean years of schooling increased by 7.2 years and expected years of schooling increased by 1.9 years. In terms of GNI, Germany’s per capita increased by about 68.2 conversely to UAE, during the same period of time.

Alcohol in the body

After the ingestion of the alcohol by the man, it passes from the stomach then to the intestines and into the blood stream in a process called absorption. This alcohol is then broken down by body chemicals called enzymes. In this case alcohol is converted to acetaldehyde after a mediation of an enzyme called Alcohol Dehydrogenase (ADH). ADH is believed to cause non-dehydration symptoms of hangover, like nausea. This process occurs in the liver. Under the influence of other enzymes acetaldehyde is quickly converted to acetate which is eventually reduced to water and carbon dioxide.An enzyme called cytochrome in the liver metabolizes the liver. This enzyme is increased in the event of continuous heavy drinking by the person in question. Although large percentage of alcohol consumed is metabolized in the liver, some small portions of unmetabolized alcohol will still find their way in urine of the individual. It is also likely to find some portions in breath. 30 to 45 minutes of after wi ll see the man’s blood alcohol level rise.Despite the amount of alcohol consumed by the individual, the liver will only be able to metabolize a specified amount of alcohol per hour. This rate of alcohol metabolism depends on the amount of metabolizing enzymes in the liver of the guy. This amount of enzymes varies from one individual to another. It appears to have some genetic determinants. Alcohol is absorbed more slowly than it is consumed. Consequently, the consumption needs to be checked to reduce the risk of it accumulating in the body due to its slow metabolism. Alcohol can even intoxicate the body.
