10 Facts About the Geography of Reykjavik, Iceland
10 Facts About the Geography of Reykjavik, Iceland Reykjavik is the capital city of Iceland. It is also the largest city in that country and with its latitude of 64ÃÅ¡08N, it is the worlds northernmost capital city for an independent nation. Reykjavik has a population of 120,165 people (2008 estimate) and its metropolitan area or the Greater Reykjavik area has a population of 201,847 people. It is the only metropolitan area in Iceland. Reykjavik is known as being Icelands commercial, governmental and cultural center. It is also known as being the worlds Greenest City for its use of hydro and geothermal power. What to Know About Iceland The following is a list of ten more facts to know about Reykjavik, Iceland: 1) Reykjavik is believed to have been the first permanent settlement in Iceland. It was established in 870 C.E. by Ingà ³lfr Arnarson. The original name of the settlement was Reykjarvik which loosely translated to the Bay of Smokes due to the regions hot springs. The additional r in the citys name was gone by 1300. 2) In the 19th century Icelanders began to push for independence from Denmark and because Reykjavik was the regions only city, it became the center of these ideas. In 1874 Iceland was given its first constitution, which gave it some legislative power. In 1904, executive power was given to Iceland and Reykjavik became the location of the minister for Iceland. 3) During the 1920s and 1930s, Reykjavik became the center of Icelands fishing industry, especially that of salt-cod. During World War II, the allies occupied the city, despite the German occupation of Denmark in April 1940. Throughout the war, both American and British soldiers built bases in Reykjavik. In 1944 the Republic of Iceland was founded and Reykjavik was named as its capital. 4) Following WWII and Icelands independence, Reykjavik began to grow considerably. People began to move to the city from Icelands rural areas as jobs increased in the city and agriculture became less important to the country. Today, finance and information technology are important sectors of Reykjaviks employment. 5) Reykjavik is the economic center of Iceland and Borgartà ºn is the financial center of the city. There are over 20 major companies in the city and there are three international firms with headquarters there. As a result of its economic growth, Reykjaviks construction sector is also growing. 6) Reykjavik is considered a multicultural city and in 2009, foreign-born peoples made up 8% of the citys population. The most common groups of ethnic minorities are Poles, Filipinos, and Danes. 7) The city of Reykjavik is located in southwest Iceland at only two degrees south of the Arctic Circle. As a result, the city gets only four hours of sunlight on its shortest day in the winter and during the summer it receives almost 24 hours of daylight. 8) Reykjavik is located on Icelands coast so the citys topography consists of peninsulas and coves. It also has some islands that were once connected to the mainland during the last ice age about 10,000 years ago. The city is spread out over a large distance with an area of 106 square miles (274 sq km) and as a result, it has a low population density. 9) Reykjavik, like most of Iceland, is geologically active and earthquakes are not uncommon in the city. In addition, there is volcanic activity nearby as well as hot springs. The city is also powered by hydro and geothermal energy. 10) Although Reykjavik is located near the Arctic Circle it has a much milder climate than other cities at the same latitude due to its coastal location and the nearby presence of the Gulf Stream. Summers in Reykjavik are cool while winters are cold. The average January low temperature is 26.6ÃÅ¡F (-3ÃÅ¡C) while the average July high temperature is 56ÃÅ¡F (13ÃÅ¡C) and it receives about 31.5 inches (798 mm) of precipitation per year. Because of its coastal location, Reykjavik is also usually very windy year round. Sources:Wikipedia.com. Reykjavik - Wikipedia, the Free Encyclopedia.

Narrative Speech Essay Example | Topics and Well Written Essays - 250 words
Narrative Speech - Essay Example Indeed, I was happy and executed at the opportunity of exploring new cultures and the education system making it difficult to focus on the tasks at home. However, my parents were not excited since they indicated that I would lose my traditional values and struggle for resources. Apparently, these are effects of immigration based on their research. As my family said goodbye during departure, I acknowledged that it would be difficult for them to visit due to the stringent immigration laws. Indeed, foreigners in the US are often mistaken as persons in search of opportunities to further their dreams; however, this is rarely the case. Indeed, I felt horrible that I was leaving my family behind. Nevertheless, I marveled at the chance of meeting new people. As I landed and exited from JFK, I noticed that the US was significantly developed as compared to my home country. The buzzing cars and skyscrapers were breathtaking; however, I began missing home since everything seemed different. Indeed, I was experiencing culture shock. I immediately bought a hot dog since I was hungry. Alas! I was already abandoning my culture since I devalue fast food. As I settled down, I found a job and attended school; however, I miss big family. I realized that immigration distorts oneââ¬â¢s culture since I am accustomed to fast foods; furthermore, I intend to look for additional jobs to keep up indicating that immigrants struggle for resources. In conclusion, it is clear that immigration is a social problem because it leads to loss of values and struggle for resources (Spijkerboer & Walsum

The Influence Of Mass Media On Drug Abuse In The Society Essay
The Influence Of Mass Media On Drug Abuse In The Society - Essay Example The internet is also a mass media channel that includes e-mails, websites, blogs and social networking sites (Armstrong 34). Mass media messages especially advertisements of entertainment video clips contain drug abuse messages that influence the attitudes of the youth towards consumption of illicit drugs (Primack, Kraemer, Fine and Dalton 27). The teenagers lack the cognitive capabilities to understand the dangers of drug abuse and imitate the lifestyles of entertainment celebrities thus leading to high drug abuse in the society. Thesis statement: the mass media has fuelled drug abuse among teenagers in the society. The influence of mass media in drug abuse among the teenagers cannot be underestimated. The mass media has created a new drug abuse culture among the teenagers Wagner 67). The mass media advertising contains drug abuse messages that create wrong perceptions of prosperity by showing images of drug abusers enjoying material things like luxury cars and expensive jewelry (Pr imack, Kraemer, Fine and Dalton 35). The mass media has created numerous stereotypes about drug abuse, fashion and violence thus leading to a sensation of drug abuse and sex among teenagers in the United States. ... The teenagers mainly rely on the mass media for entertainment and connecting with their peers (Wagner 81). Currently, the mass media contains a lot of information, images and audio-video clips that depict drug abuse as something rewarding and cool. Although there is controversial debate surrounding the impact of mass media on drug abuse among the youth, it is true that mass media messages affect the perceptions of youth towards drugs (Primack, Kraemer, Fine and Dalton 19). The mass media is increasingly being used to advertise tobacco related products, alcohol and other prescription drugs. Accordingly, teenagers who smoke tobacco and take alcohol have higher chances of engaging in illicit drug abuse. Cigarette advertising messages glamorize smokers and smoking through depicting the smokers as young, cool, adventurous, independent and healthy (Primack, Kraemer, Fine and Dalton 31). Accordingly, teen-oriented television programs and magazines have tobacco-related advertising that conta ins images that are tailor-made in order to appeal to the youths. The audio-clips use images that show young people as fun-loving and enjoying consumption of illicit drugs. The internet is contains massive videos and messages related to drug abuse and often portray positive consequences of drug abuse and desirable attributes like feelings of relaxation or greatness (Primack, Kraemer, Fine and Dalton 12). Some of the factors that expose teenagers to unrestricted drug related advertising and violent movies that contain images of drug abuse include poor parenting, aggressive tobacco related advertising and peer pressure (Brown, Steele and Walsh-Childers 44). A majority of the

As I Lay Dying (book) Essay Example for Free
As I Lay Dying (book) Essay The character Addie Bundren is portrayed in many ways throughout the novel As I Lay Dying. The whole story revolves around the fact that Addie is dead and her wish to be buried near her blood relatives rather than her own family. The impression the reader gets of Addie is developed through many different charactersââ¬â¢ views and descriptions of Addie. One character that helps us understand Addieââ¬â¢s personality a little more is Cora Tull. Cora Tull, Vernon Tullââ¬â¢s wife, expresses Addieââ¬â¢s voice and personality through her memories of Addie. Cora stood with Addie during her final hours. Cora disapproves of Addieââ¬â¢s behavior and lack of religion. Cora dislikes the fact that Addieââ¬â¢s love for Jewel is greater than her love of God. Another character that helps us understand Addie is Minister Whitfield. Addie had an affair with the minister and had a baby. This affair shows how Addie sees marital love and motherhood as empty concepts and are just there to fill empty voids. Addie doesnââ¬â¢t have an affair with the minister solely on lust, but she does it for self-gratification and self-expression also. Vardaman, the youngest of the Bundren children, compares his motherââ¬â¢s death to a fish he recently caught and cleaned. Vardaman compares his mother to a fish because the fish and his mother have both died. The fish and his mother have changed because of death. Both Addie and the fish no longer have essence, which could be interpreted as an existentialist view. In a chapter where Addie seemingly speaks from the dead, Addieââ¬â¢s personality is truly shown. We learn that Addie is a pessimistic and unfulfilled woman, who marries her ignorant husband Anse. She admits to only caring for two of her children and the rest she calls or labels as ââ¬Å"Anseââ¬â¢s childrenâ⬠, who were born out of an obligation. Addieââ¬â¢s personality is put together by the views, comparisons, and descriptions of her youngest son Vardaman, her neighbor Cora Tull, The affair she had with Minister Whitfield, and her own personal voice. Through these views, we could conclude/interpret that Addie was a strong-willed and intelligent woman who dislikes the obligations put on women during that time period. Cora Tull shows her as some who lacks religion. The affair with the minister shows that she is a woman who needed gratification. Her youngest son shows how she is a mother who was completely lost in death and no longer has essence. Her own voice shows that she is a person who feels like women are obligated to fit into the roles of being a mother and a wife.

Rigidity of Puritanism Exposed in Hawthornes Young Goodman Brown Essay
Rigidity of Puritanism Exposed in Young Goodman Brown à Proverbs 10:28 implies the idea of the universality of sin in saying "The prospect of the righteous is joy, but the hopes of the wicked come to nothing."à In "Young Goodman Brown", Nathaniel Hawthorne illustrates this through Brown's actions.à When Brown lives a righteous life with good faith, his thoughts remain pure and happy.à He has a wonderful wife, and he enjoys the presence of everyone.à As he takes his walk into the forest and into evil ways, his hopes and faith disappear.à He no longer loves his wife in the same way, and he despises everyone whom people consider were holy.à When he loses his faith, he loses his happiness. à To regain his happiness, Brown must find his righteousness again. Puritans believe there is no hope for a sinner.à Hawthorne uses a variety of writing techniques to condemn the rigidity of Puritanism. à à à à à à For example, Hawthorne uses a wide variety of diction to create a mystical and hopeless mood.à As Brown walks into the "dreary" forest, an " uncertain" feeling comes over him as he looks ahead to the "gloom" awaiting him.à The forest is very dark and dreary and these words help create the eerie mood.à These words create an insecure and unsure feeling in the reader's mind.à The reader feels as if he stands right there on the outskirts of the forest along with Brown. That type of feeling scares even the bravest of men.à Hawthorne also describes the events taking place in the forest as "devilish," "horrid," and "evil."à Evil completely surrounds Brown in the forest.à It puts a thought in him which drives him crazy. These words give a v... ...ands before him with the guilt of sin. à à He can never remember these people in the same way in which he wants to. His views on the righteousness of humanity change from good to bad.à Hence, Brown loses his comradery with his neighbors, and he dies a lonely death with no hopeful verse on his tombstone. à Works Cited Benoit, Raymond.à "'Young Goodman Brown': The Second Time Around."à The Nathaniel Hawthorne Review 19 (Spring 1993): 18-21.

Wind energy
Wind power is the conversion of wind energy into a useful form of energy, such as using: wind turbines to make electricity, windmills for mechanical power, wind pumps for water pumping or drainage, or sails to propel ships. A large wind farm may consist of several hundred individual wind turbines which are connected to the electric power transmission network. Offshore wind farms can harness more frequent and powerful winds than are available to land-based installations and have less visual impact on the landscape but construction costs are considerably higher.Small onshore wind facilities are used to provide electricity to isolated locations and utility companies increasingly buy back surplus electricity produced by small domestic wind turbines. Although very consistent from year to year, wind power has significant variation over shorter timescales. The intermittency of wind seldom creates problems when used to supply up to 20% of total electricity demand, but as the proportion incre ases, a need to upgrade the grid, and a lowered ability to supplant conventional production can occur.Power management techniques such as having excess capacity storage, dispatch able backing supplies (usually natural gas), storage such as pumped-storage hydroelectricity, exporting and importing power to neighboring areas or reducing demand when wind production is low, can greatly mitigate these problems. Wind power, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation and uses little land Any effects on the environment are generally less problematic than those from other power sources.As of 2010 wind energy production was over 2. 5% of worldwide power, growing at more than 25% per annum. The overall cost per unit of energy produced is similar to the cost for new coal and natural gas installations. Although wind power is a popular form of energy generation, the construction of wind farms is not u niversally welcomed. Fossil fuels are subsidized by many governments, and wind power and other forms of renewable energy are also often subsidized. For example a 2009 study by the Environmental Law Institute assessed the size and structure of U. S. energy subsidies over the 2002ââ¬â2008 periods.The study estimated that subsidies to fossil-fuel based sources amounted to approximately $72 billion over this period and subsidies to renewable fuel sources totaled $29 billion. In the United States, the federal government has paid US$74 billion for energy subsidies to support R&D for nuclear power ($50 billion) and fossil fuels ($24 billion) from 1973 to 2003. (Energy subsidies are measures that keep prices for consumers below market levels or for producers above market levels, or reduce costs) During this same timeframe, renewable energy technologies and energy efficiency received a total of US$26 billion.It has been suggested that a subsidy shift would help to level the playing field and support growing energy sectors, namely solar power, wind power, and biofuels. History shows that no energy sector was developed without subsidies. According to the International Energy Agency (IEA) (2011) energy subsidies artificially lower the price of energy paid by consumers, raise the price received by producers or lower the cost of production. ââ¬Å"Fossil fuels subsidies costs generally outweigh the benefits.Subsidies to renewables and low-carbon energy technologies can bring long-term economic and environmental benefitsâ⬠. In November 2011, an IEA report entitled Deploying Renewables 2011 said ââ¬Å"subsidies in green energy technologies that were not yet competitive are justified in order to give an incentive to investing into technologies with clear environmental and energy security benefitsâ⬠. The IEA's report disagreed with claims that renewable energy technologies are only viable through costly subsidies and not able to produce energy reliably to meet de mand.In the US, the wind power industry has recently increased its lobbying efforts considerably, spending about $5 million in 2009 after years of relative obscurity in Washington. By comparison, the US nuclear industry alone spent over $650 million on its lobbying efforts and campaign contributions during a single ten year period ending in 2008. Following the 2011 Japanese nuclear accidents, Germany's federal government is working on a new plan for increasing energy efficiency and renewable energy commercialization, with a particular focus on offshore wind farms.Under the plan large wind turbines will be erected far away from the coastlines, where the wind blows more consistently than it does on land, and where the enormous turbines won't bother the inhabitants. The plan aims to decrease Germany's dependence on energy derived from coal and nuclear power plants. Commenting on the EU's 2020 renewable energy target, Economist, Professor Dieter Helm, is critical of how the costs of win d power are cited by lobbyists. Helm also says that the problem of intermittent supply will probably lead to another dash-for-gas or dash-for-coal inEurope, possibly with a negative impact on energy security. A House of Lords Select Committee report (2008) on renewable energy in the UK reported a ââ¬Å"concern over the prospective role of wind generated and other intermittent sources of electricity in the UK, in the absence of a break-through in electricity storage technology or the integration of the UK grid with that of continental Europe. Many wind power companies work with local communities to reduce environmental and other concerns associated with particular wind farms. In other cases there is direct community ownership of wind farm projects.Appropriate government consultation, planning and approval procedures also help to minimize environmental risks. Some may still object to wind farms but, according to The Australia Institute, their concerns should be weighed against the ne ed to address the threats posed by climate change and the opinions of the broader community. In America, wind projects are reported to boost local tax bases, helping to pay for schools, roads and hospitals. Wind projects also revitalize the economy of rural communities by providing steady income to farmers and other landowners.In the UK, both the National Trust and the Campaign to Protect Rural England have expressed concerns about the effects on the rural landscape caused by inappropriately sited wind turbines and wind farms. Some wind farms have become tourist attractions. The White lee Wind Farm Visitor Centre has an exhibition room, a learning hub, a cafe with a viewing deck and also a shop. It is run by the Glasgow Science Centre. In Denmark, a loss-of-value scheme gives people the right to claim compensation for loss of value of their property if it is caused by proximity to a wind turbine.The loss must be at least 1% of the propertyââ¬â¢s value. There have been numerous re ports of those living close to wind turbines suffering adverse health effects from noise, vibration and shadow flicker, and in 2009 New York Pediatrician, Dr. Nina Pierpont, claimed to have identified an effect for which she coined the term ââ¬Å"Wind Turbine Syndromeâ⬠. An industry commissioned review of the current research on the possible health effects of wind turbine noise and vibration reported in 2010 that, ââ¬Å"the sound (including sub audible sound) is not unique, and does not pose a risk to human health.Although the sound may cause ââ¬Ëannoyanceââ¬â¢ for some people, this in itself is not an adverse health effect. â⬠The findings of the report have, however, been questioned on a number of grounds including; that the reviewing group did not include an epidemiologist, usually a given for assessing potential environmental health hazards, and that there was no clear description of the methods the researchers used to search for available research, nor how the y rated the quality of the research. In October 2010 The Society for Wind Vigilance held an international symposium concerning the subject.A study on wind farm noise published in 2012 by The US state of Massachusetts reported that people are annoyed by sound from wind turbines at far lower sound levels than they are by noises from railroads, aircraft, or road traffic. The study found the percentage of respondents who found noise levels highly annoying rose quickly as sound levels increased above about 37dbA (about the level of a conversation).

Putting Global Warming on Ice Essay
What makes the earthââ¬â¢s temperature rise and fall? Do greenhouse gases block solar heat from leaving the earth, or is it only a product of solar activity? Many people have theorized on what causes temperatures to change. A catch phrase named Global Warming came to popularity. Environmentalists from all walks of life joined the ââ¬Ëglobal warmingââ¬â¢ fight. According to Thomas Oââ¬â¢Connell the global warming debate wasnââ¬â¢t accepted in the 60ââ¬â¢s and 70ââ¬â¢s when he studied it. It only became popular recently in the 90ââ¬â¢s. Everyone believed that humans were causing a catastrophe by punching a whole into an ââ¬Ëozone layerââ¬â¢ in the sky, letting harmful rays of sun in. People fought to shutdown plants in order to stop the emissions of carbon dioxide and other ââ¬Ëgreenhouse gasesââ¬â¢. Everyone believed the global warming claims coming from senators and environmentalists. Today in the 21st century, science has stepped up to disprove the common myths of global warming. Many of the theories and claims of global warming are easily disproved with science. Science is the only tool that can be used to tell whether theories are fact or fiction. The first issue of global warming is the recent Kyoto Protocol, an international treaty designed to cut greenhouse emissions from successful countries. The international Kyoto protocol has been in debate for many years. The Kyoto protocol is an international treaty to reduce developed countryââ¬â¢s greenhouse emissions, specifically carbon dioxide, to 7% below their 1990 levels. As President Bush came to office he refused the U.S.ââ¬â¢s involvement in the treaty. President Bush wasnââ¬â¢t even the man that killed the idea for the U.S. (National Center 2). A bill, stating that the U.S. wouldnââ¬â¢t ratify any climate treaty that would harm the United States economically and would have no consequences for developing or ââ¬Å"3rd Worldâ⬠countries, was passed with a unanimous 95-0 vote by the senate before President Bush was elected (National Center 2). The treaty isnââ¬â¢t about global warming. It was designed in order to transfer success from developed nations like the U.S. to developing or struggling countries (Tuccille 2). Research declares that China, India, and Brazil who are not affected by the Kyoto Protocol will increase their CO2 emissions by 16% more than the United States even withoutà the Protocol in effect (National Center 3). Proponents of the protocol confessed that the treaty ââ¬Å"would not have the beneficial environmental impacts advertisedâ⬠and that ââ¬Å"the costs of implementation would be much higher than the public had been toldâ⬠(National Center 1). U.S. economy would suffer if we agreed to partake in the Kyoto scheme. Gasoline prices would increase by as much as 66 cents per gallon, electrical costs would also increase up to 80%, energy intensive products such as chemicals, steel, paper, and cars would rise in price by as much as 15%. (National Center 2). ââ¬Å"The economy of the USA would be devastated,â⬠states Thomas Oââ¬â¢Connell. The minority income would be lowered by about 10%, 864,000 African Americans as well as 511,000 Hispanics would be unemplo yed (National Center 2). Oil and fuel used for farming would be taxed or restricted causing in a higher cost of producing and lower profits of products including corn, soybeans, wheat, cotton, hogs, and milk (Heartland Institute 2 and 3). Businesses taxed by the government for their emissions would result in raising costs for their consumers (Heartland Institute 3). New regulations would be implemented for automobiles making carpooling mandatory and would penalize owners of trucks and sports cars. The average household income would even drop by about $2,700 (Heartland Institute 2). Even the unbiased and credible Time magazine quoted, ââ¬Å"the campaign against global warming seemed to be over before it even startedâ⬠referring to the Kyoto Protocol (Tuccille 1). Are we prepared to ââ¬Å"disappear from the mapâ⬠in order to prevent 1 degree Celsius of warming for the next Century? One of the hot issues on global warming is that humankind has had something to do with the temperature. Man-made emissions such as carbon dioxide have been claimed to cause global temperatures to increase over the years. Ever since the industrial revolution in the 1940ââ¬â¢s man has continued to emit gases such as CO2 into the air. Many people claim that CO2 is what blocks heat from escaping the atmosphere. They also claim that mankind has poked a hole in something called the ââ¬Å"ozone layerâ⬠, a protective layer above the atmosphere that keeps harmful UV radiation out, which lets more solar rays in. How convenient. The fact is that 98% of these ââ¬Å"greenhouse gasesâ⬠are natural to the earth. Man has not emitted them and they are not pollutants. They are mostly water vapors and clouds (Zipperer 2). Does that sound dangerous to you? The earthà has even cut down on the rate of carbon dioxide emissions from the years 1973-1990 (Lindzen 1 and 2). Even if we did have a lot of CO2 in the air evidently the effects wouldnââ¬â¢t be catastrophic. In the past the atmosphere has had much more amounts of CO2 in it before without significant increases in temperature (Lindzen 4). Richard Lindzen, a professor of meteorology at MIT, claims that a doubling of CO2 in the earthââ¬â¢s atmosphere would only result in a 1 degree Celsius increase in global temperature (National Center 3). Another greenhouse gas is methane. Methane is more harmful than CO2 but will not increase significantly for another 100 years if it continues at its current rate (Michaels 1). Many credible experts in the field of science have agreed that man is not responsible. Over 17,000 scientists from all over the world have signed a petition declaring that ââ¬Å"there is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the earthââ¬â¢s atmosphere and disruption of the earthââ¬â¢s climateâ⬠(Heartland Institute 5). Even if there were significant cases of warming global temperatures the effects wouldnââ¬â¢t be as tragic as everyone thinks. There are many benefits to the warming of the earth, as there are consequences. Warming on a global scale would have dramatic effects on life and climates. Some effects may be harmful but many of them are beneficial. Some ideas about global warming consequences are myths that are unlikely. Many people say that global warming is linked with the uprising in tropical storms. Storms such as hurricanes coming from the southeast into Florida coasts have been getting stronger for many years, but in 1991 there was a drought of storms that ranged to 1995. The amount and intensity fell way below the average, which suggests that these storms were not affected by the warming of the earth (Bible Believers 3 and 4). Others claim that sea levels have risen all over the world because the polar ice caps are slowly melting due to the warming. Tests have proven that temperatures at the poles are actually getting colder and that sea levels have been rising for centuries before we had any affect on the c limate (Bible Believers 3). Former Vice President Al Gore spoke of diseases migrating due to climate warming. He spoke of diseases like the Black Plague and Cholera, which he believed wereà spread because of weather patterns. Rats, who spread the Black Plague, lived in both warm and cold climates so they had no reason to migrate. His second example Cholera has been a problem in both warm and cold climates and can be easily treated by purifying the water we drink (Heartland Institute 9). Many people have never heard possible benefits of global warming before. Having a warmer climate is very beneficial. Historically, very warm periods in time resulted in flourishing life such as plants, animals, and fish (Bible Believers 4). Even large amounts of CO2 can be beneficial. More CO2 in the atmosphere fuels plants, which makes more food for all walks of life. Vikings were once able to farm what is now a cold and icy Greenland (Zipperer 3). A warming of the earth would result in longer growing seasons and would deplete world hunger and crop failure (Robinson 3). Global warming wouldnââ¬â¢t be all that bad, but we do not have a way to tell if there is or will be any warming because of the difficulty to predict the weather. In order to make predictions about weather, people have designed computer models that estimate changes in weather patterns. The models are designed from past weather data and possible factors effecting the weather. What modelers do not know is that global weather is very hard to predict, maybe even impossible without the right understanding and tools for the job (Robinson 2). Factors such as clouds, precipitation, oceans, and the sun are misunderstood and often underestimated (Zipperer 2). Modelers also leave out possible advances in the future such as nuclear energy and the positive effect it would have on the environment (Lindzen 2). Our current technology isnââ¬â¢t even close to being advanced enough. Errors in the data are equivalent to 50% (Lindzen 3). These computer models could not even predict weather from the past. While global temperatures have raised by .3 to .6 C over the past 100 years models have over predicted the increase to be from .7 to 1.4 C by the year 1990 (Heartland Institute 7). Climate modelers have even inputted their own bias into the data, shifting variables to what they want them to be. ââ¬Å"Climate modelers have been cheating for so long itââ¬â¢s almost become respectable,â⬠says Richard A. Kerr, a writer for Science magazine. Further research on the topic is necessary in order to accurately determine whether we have a problem or not. Many people of profession have studied global warming and what may affect the outcome of their results. When measuring from the surface global temperatures have increased by about .6 degrees Celsius with a .2-degree error, but parts of the United States including the southeast have cooled slightly since the late 19th century (NOAA 2). For those 100 years of slight warming, 70% of it occurred before the industrial revolution in 1940 in which man began to emit gases into the air (Zipperer 2). The surface on and around the equator has remained plus or minus 1 degree Celsius of its current temperature for billions of years (Lindzen 4). Research has also been done to determine the affect on rising and falling temperatures. Scientists have found very close relations with solar activity from the sun and the current temperature patterns, which suggests that fluctuations in temperatures are out of our hands (NOAA 5). Satellites are the best way to determine global temperatures. They are unbiased and have only a 0.001-degree Celsius of error (Heartland Institute 6). These satellites have confirmed that there is no evidence of global warming. If anything there is a slight cooling in the atmosphere (National Center 3). Very reliable agencies have done their own research on global warming. Many scientists have tested the greenhouse theory carefully and have found that greenhouse warming isnââ¬â¢t even occurring and that rising temperatures are do to different stages of solar activity (Robinson 1). In 1995 the IPCC, Intergovernmental Panel on Climate Change, did not prove that humans were affecting global temperatures (Heartland Institute 8). Their report, Climate Change, includes a statement, ââ¬Å"The balance of evidence suggests a discernible human influence on the global climateâ⬠(Heartland Institute 8). Dr. Roy Spencer, a meteorologist and team leader of the NASA/Marshall Space Flight Center, quotes, ââ¬Å"The temperatures we measure from space a re actually on a very slight downward trend since 1979â⬠¦ the trend is about 0.05C per decade coolingâ⬠(Heartland Institute 7). In a recent poll only 17% of the meteorological society and the American Geophysical Society believe that global warming is a product of man (Bible Believers 2). Representatives from the Environmental Protection Agency are threatening to withdraw their support from a global warming study done by the government. They have said that the report has an ââ¬Å"extreme/alarmist toneâ⬠and that it does not ââ¬Å"appear to fairly reflect the scientific literature and the historical recordâ⬠à (Torres 1). The representatives claimed that the report also had ââ¬Å"scientifically inaccurate statements about the potential implications of climate change for air pollution and humanâ⬠(Torres 1 and 2). Usually, in scientific law, if a hypothesis fails through experimentation it should be discarded, but the theory of global warming and greenhouse gases as a result of man is still considered substantial hypothesis even though it has been proven to be unlikely (Robinson 2). The debate of global warming may continue on for many years to come. Mankind may never see any rising in global temperatures, but nevertheless it will be speculated. Thomas Oââ¬â¢Connell At this moment in time there has not been any reliable and convincing evidence that the globe is dangerously warming. Global temperature is a product of natural variables that affect the earth. Man has little if any influence on this temperature. Many of the greenhouse claims have been poorly researched and have yet to be proven credible. Hopefully in the future science will prevail and provide the real answer. Until then, people interested in global warming should do research of their own in order to formulate their own opinion. Life on earth has adapted or evolved to the environment. The earth will never adapt or change due to a single species; the earth is far too powerful. As this paper comes to a close a quote sums up the main idea. Thomas Oââ¬â¢Connell once said, ââ¬Å"As the rhetoric of the proponents gives way to real problem or is this phenomena more closely related to political agendas. Iââ¬â¢ll wait for the science.ââ¬

Electronic Range Finders
Electronic Range Finders A range finder is an electronic surveying device used to measure distances between an observer and a target. Since its invention, the device has enhanced focus in numerous photography processes. In addition, it has enhanced perfect shots in the field of ballistics. Advertising We will write a custom essay sample on Electronic Range Finders specifically for you for only $16.05 $11/page Learn More The device has an inbuilt technology, which constitutes of sonar, laser, radar and trigonometry. These aspects facilitate accurate measurements of the distance of a target from an observer. All these technologies have facilitated the measurement of targetsââ¬â¢ distances or sizes and have been in application since18th century. The first range finder device, named telemeters, was invented in the 19th century. It was not until 1916 that Kodak unveiled them into the market. In history, Kodak became the first company to include this device in 3A cameras. In 1925, the Leica I camera extensively incorporated range finders and as a result popularized the technology. In the preceding years, Leica II and Zeiss Contax I cameras were developed as 35mm rangefinder cameras. Between 1930 and 1970, rangefinder cameras became considerably popular. During this period, range finder devices were manufactured in various sizes. In the early 1960s, the devices were actively fitted in the most expensive cameras. As result, several manufactures, among which were Japanese companies including Canon, Minolta, Olympus and Ricoh, focused on the production of the 35mm rangefinder camera. Although more sophisticated auto-focus devices later outnumbered the range finders, some of these cameras are still in use today. In 2004, digital imaging technology was incorporated into the first rangefinder camera (Epson R-D1) reviving their use. Unlike SLRs, range finder devices are prone to parallax errors. Thus, during close-up photography, rangefinder cameras are ineffective. No netheless, range finder devices outshine the SLR devices in some features. In contrast to the SLR devices, range finder devices do not have moving mirrors. This eliminates momentary blackout of the subject under focus. Similarly, range finder devices, as compared to SLRs, are quieter, smaller and less conspicuous. Coupled with these features, rangefinder cameras are more suited for theatre photography, street photography and portrait photography.Advertising Looking for essay on other technology?

Likewise, with the absence of mirrors, rangefinder camerasââ¬â¢ rear lenses project deep into the deviceââ¬â¢s body resulting in superior wide-angled lenses. As compared to SLRs, rangefinder viewfinders have a wide field of view allowing the user to observe actions outside the frame. Si milarly, the color filters in SLRs make it difficult to focus, view and compose using SLR cameras. However, these processes remain unaffected with the application of range finders. Since their invention, rangefinder devices have found numerous applications in various fields. These include ballistics, photography, forestry and virtual reality. Rangefinders were first used in the field of ballistics by military snipers in calculating the distances between them and their shooting targets. However, during ballistic operations, snipers should avoid the use laser rangefinders as the option sends out light sources that might indicate their positions to their enemies. In photography, rangefinder devices have allowed photographers to take focused and clear photographs by measuring the distance between them and their subjects. With improvements in this technology, forestry surveys have considerably used range finders. During these operations, special devices fitted with anti-leaf equipments a re employed. Furthermore, virtual reality systems use range finders as they help in indicating the position of objects.

How to Answer the ââ¬ÅWhatââ¬â¢s Your Biggest Weaknessââ¬Â Question in Interviews
How to Answer the ââ¬Å"Whatââ¬â¢s Your Biggest Weaknessâ⬠Question in Interviews People typically have a really hard time answering the ââ¬Å"what is your biggest weakness?â⬠question. It goes against all of the self-promotion cramming people do when on the job market. How can I portray myself as the ideal candidate and then start talking about the ways in which Iââ¬â¢m not ideal? As it turns out, this is an important question- and one that most interviewees botch. Keep in mind that, first of all, there is no right answer. But you should have a good one all the same.Spin it as aà Growth ExperienceTry rethinking it as an opportunity for you to show how you have faced a particularly large obstacle in the past, and how you learned and grew from that experience. Reframe the question into showing how you deal with your flaws productively, rather than trying to humblebrag and pick a non-flaw (i.e. ââ¬Å"Iââ¬â¢m too much of a perfectionistâ⬠â⬠¦ hiring managers see right through this).Use it to Show Youââ¬â¢re Not Perfect (Itââ¬â¢s Okay!)Con fidence is important, but humility is also. Hiring managers want to see a lot from column A, but also a healthy dose of that little bit of honesty and willingness to confront oneââ¬â¢s weaknesses from column B.You know you have weaknesses. So try to figure out a way to A) be honest about them, and B) turn them somehow to your advantage. There are stories out there about candidates who open their cover letters by zeroing in on their potential weaknesses or holes in their resume, rather than trying to bury that lack of experience in their resumes. Think along the lines of: ââ¬Å"At first glance, I know Iââ¬â¢m not the candidate youââ¬â¢ve envisioned.â⬠That sort of opening salvo of honesty will certainly grab a hiring managerââ¬â¢s attention, and it will give you a chance to frame your candidacy in the best possible light (i.e. ââ¬Å"Butâ⬠¦ I am uniquely qualified becauseâ⬠¦.â⬠).Explain That You Are Always Fine-TuningRemember that admitting your inadequ acies doesnââ¬â¢t show that youââ¬â¢re inadequate. Quite the contrary. It usually shows that you are self-aware, and that you take the time to examine the parts of your success-machine that are in need of tune-ups or replacements. That you are constantly trying to improve. Thatââ¬â¢s often the kind of quality that any employer would be very keen to have in an employee.So prepare. But donââ¬â¢t go into an interview with a canned response. Come up with something that can segue into a story of overcoming obstacles, and keep it work related. Show youââ¬â¢re human, but hardworking, and youââ¬â¢ll never be on the wrong end of this ubiquitous interview question again.

The Bound between Corruption and Guanxi in the Chinese Society Coursework
The Bound between Corruption and Guanxi in the Chinese Society - Coursework Example The current state of literature provides an insight into what Guanxi is and how it works. Understanding the meaning of Guanxi is of vital importance for everyone who seeks to look deeper into the significance of corruption in the Chinese business system. Surprisingly or not, different authors provide different meanings of the term Guanxi. However, these differences are natural and even anticipated, given the complexity of the Guanxi concept and the multitude of meanings which it comprises. According to Chatterjee, Pearson, and Nie, the Chinese definition of Guanxi is hard to translate in one phrase ââ¬â countless meanings are included in it, and it is fairly considered as one of the most impactful phrases in Chinese business contexts. However, it is possible to say that Guanxi can be roughly divided into the three basic groups of meanings: first, Guanxi presupposes the development of a relationship between people with a similar status; second, relevant and continuous connections between people; and third, contacts with people with little or no direct interactions. For the Chinese people, Guanxi exemplifies a type of special relationships in which one person needs something and another person has something to give. Guanxi is a highly dynamic form of relations between business people in China. Furthermore, even if a person who has resources and opportunities to solve a problem enters a Guanxi relationship, he (she) is not obliged to solve such a problem or respond to another individualââ¬â¢s request. Third, Guanxi is not a continuous phenomenon but emerges only the moment a person needs another person to do something important or solve some problem. Finally, Guanxi is almost always a sequence of previously planned activities aimed to resolve a business or personal issue. Here, western managers and people come to view Guanxi as a form of corruption, as long as such activities and relations may range from a simple meal together to giving gifts or doing favors. à However, whether Guanxi can be considered as a form of corruption remains a difficult question.
