Ebay - Research Paper Example The sellers have the choice of accepting bids for their products. They can also use the Buy It Now option that provides the buyers with the opportunity to buy the product at a fixed price right away. Bidding in the online auction system starts at a price established by the seller and remains on the eBay for some days so that the buyers can place their bids. At the end of the listing, the buyer who has the maximum number of bids wins. On the other hand, when the Buy It Now option is used, the first buyer who is volunteering to pay the price established by the seller receives the item. The online auction website was established in the year 1995 as the AuctionWeb. Pierre Omidyar, an Iranian computer programmer born in France founded AuctionWeb on 3 September 1995 in San Jose, California (â€Å"The history of†). The first employee was recruited by eBay in the year 1996. eBay entered its first deal of third-party licensing in November 1996 with Electronic Travel Auction. It made use of the SmartMarket Technology to sell travel products and tickets of planes. In January 1997, over 2000000 auctions were hosted by eBay in comparison to 250000 that were hosted during the year 1996. In September 1997, the company’s name was officially changed from AuctionWeb to eBay after it received $6.7m from Benchmark Capital. â€Å"To save money, Omidyar linked the new Web site with an existing site he had created for his consulting and technology business, Echo Bay Technology Group. The Web address for that business was ebay.com† (Gitlin). The number of eBay†™s employees increased to 20 by March 1998 along with a population of half a million users. Its revenues in the US reached $4.7m (â€Å"The history of†). In 21 September 1998, eBay went floated over the stock exchange that resulted in the making of the founders of the company, billionaires. On the very first day of trading, the price of target shares of eBay increased from $18 to $53.50. eBay

Economic Policy of Obama and McCain Essay Example | Topics and Well Written Essays - 1000 words

Economic Policy of Obama and McCain - Essay Example McCain claims that the country was successful in the development of the 'concept of the internationalization of national economies which required multiple measures to capture it adequately', and for this purpose the country was able to achieve prominent mark in economic indices relevant to 'economic internationalization, the volume of international commercial transactions', the candidate therefore strongly intends to continue with such plan. Democrat presidential candidate has promised that soon after his election he would impose tax cuts on wealthy, and will protect the interests of the middle class. The presidential candidate also promised appropriate usage of funds extracted through taxes; the funds shall be invested to offer health care, education and housing incentives to the middle class. The presidential candidate for Republican shared the similar belief, but he wanted people from middle class to be placed in higher tax bracket so broaden the scope of tax revenue generation. The presidential candidates Barack Obama and McCain shared difference of opinion towards tax imposition on oil exploration companies. McCain denied adoption of field specific policy towards imposition of taxes; the bracket for taxes shall be based upon profit earned by the company, and shall not be trade or industry specific. According to Robert (2008) Obama emerged as staunch supported for cut in emission gases, and for that he devised a spe cial taxation policy applicable on oil companies, "this shall cause drop in the momentum of explorations activities undertaken by the oil companies", and shall restrict their revenue generation outlook. McCain resisted such move, and wanted to adopt non-industry-specific tax policy, which shall be applicable on all and shall be function of revenue generation. Obama protested by claiming that such measure will curtail the investment plans of the companies adopted green technology. Title: Obama, McCain economic policies in spotlight as election approaches Author: Motoshige Itoh Obama has warned that the economic concerns related with the implementation of the globalization has been significant, although in some of the cases the impact has been as per the aspirations of the local traders, but in majority of the American economy has experienced jolts. Obama has evolved strategy such per which the declination on American exports shall be protected during counter measures and agreement which shall curtail the emergence of China and India as the economic hub for the Asian countries. Itoh (2008) explicitly mentioned that Democrats have expressed their intention to focus much upon the exploring the potential of US manpower and workforce, to improve the employment figure. Democrats have blamed Republicans for their failure on this particular front, and have failed to bring the shares back to its homeland. However, the corporate sector of the country in consultation with the government of United States have established their industrial units in China and India, ther efore the qualitative standards will be certified by the American company but the production will be fabricated

CORE COMPETENCIES PAPER - Dissertation Example (Holmes) Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals" (Winslow, 1920). It focuses on improving health of communities, groups of people and preventing from diseases. It may include curing from diseases, finding ways to prevent from them, making people aware of the diseases and taking measures to contribute to healthy lifestyles. There can be many reasons for different diseases. Some are sexually transmitted diseases like HIV AIDS, many are infectious like small pox, and few are caused due to lack of providing medicines at early stage of life like polio, whereas some are caused by environmental hazards. Environmental Health Hazards At every interaction with the environment, we are in contact with numerous health hazards that are caused by different pollutants and harmful substances. What we feed to our enviro nment is given back to us in the form of diseases and other health hazards. Environmental hazards are caused by chemical waste from industries, harmful substances used in these industries, land degeneration, ozone depletion, nuclear issues, over population, harmful substance used at our homes, poor sanitation, and emission of harmful gases such as carbon dioxide and carbon monoxide. Domestic and hazardous waste cause serious diseases. These wastes are divided into two categories: municipal waste by domestic activities & industrial waste by industrial activities. Municipal waste causes problem for ordinary human being if it is not disposed off in the right way. Industrial waste can cause damage to the workers in the industry as well as common man. Water contamination again causes water-borne diseases that might lead to morbidity and mortality. Clean drinking water is rare in the world. Most people do not enjoy clean water and have to quench their thirst with contaminated and polluted water. This is a very increasing concern of environmental health in entire world. Another way of causing environment related health problems is the air toxicants. Huge amounts of carbon Dioxide, carbon monoxide, and sulfur dioxide in our air are harmful for our health. A large part of air pollutants is caused by the emissions from automobiles. Besides these, in our everyday life we see consumer products full of harmful substances. Lead is one example. Lead is present in many consumer products especially paint. The manufacturers of these products put such harmful substances without realizing the high level of human interaction with these products. (Nweke & William, 2009) Children come into direct contact with environmental toxicants such as lead, methyl mercury, tobacco and other pollutants. These pollutants enter children’s bodies via placental transfer during fetal growth, inhalation of dust, breast milk and other dietary sources during early childhood. (Landrigan et al, 19 98) One of the threats from these environmental hazards is asthma in children. It is more common in children because they have smaller airways. Asthma Asthma causes the airways

Homeostasis And Goldfish Respiration Physical Education Essay

Homeostasis And Goldfish Respiration Physical Education Essay Every organism possesses a mechanism for maintaining homeostasis. Homeostasis is the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with changes in the external environment. Regulation of temperature is most definitely the most important aspect of homeostasis. Fish are cold-blooded animals. Most fish cannot control their internal body temperatures. Most fish body temperatures change with the temperature of the water around them. In order to obtain temperature homeostasis, the fish seek colder or warmer water. They lose metabolic heat through their gills. There are different types of metabolic adaptations in fish. Temperature and blood pressure are two. Cold-blooded animals must regulate their body temperature by moving. Literary Discussion Homeostasis and the Respiration of Goldfish What is Homeostasis? Homeostasis is the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes (www.biology-online.org/dictionary/Homeostasis). The main function of homeostasis is to keep all the processes of the body stable even if there are variations in the weather and environment outside (http://www.buzzle.com/articles/what-is-homeostasis.html). Regulation of temperature is most definitely the most important aspect of homeostasis. Warm blooded animals are able to retain a more adjustable constant body temperature. In humans, homeostasis happens when the body regulates body temperature in an effort to maintain an internal temperature around 98.6 degrees Fahrenheit (http://www.biology-online.org/dictionary/Homeostasis). For instance, when it is hot outside your body sweats to cool off, and we shiver to warm up during the cold seasons. Unlike humans, most fish cannot control their internal body temperatures. Fish are cold-blooded creatures. Some fish have mechanisms to keep a healthy temperature. In order to obtain temperature homeostasis, the fish seek colder or warmer water. Certain types of fish such as tuna fish control their body temperature by a specialized heat exchange system of blood vessels. Most fish are poikilothermic which means their body temperature changes with the temperature of the water around them. For instance, if the top of a pond is frozen over, the fish swims to the bottom of the pond to try to stay at a comfortable temperature. All animals create heat from metabolic activity. Metabolic activity includes breaking down food and movement (http://www.ehow.com/facts_7433473_fish-homeostasis-different-water-temperatures.html). Animals such as fish lose metabolic heat through their gills. This happens because the heated blood that runs through vessels in the gills comes into close contact with the colder water outside, and all the heat is lo st. Many diseases are a result of disturbance of homeostasis. This condition is known as homeostatic imbalance. Every organism will lose efficiency in its control systems as it ages. Homeostatic imbalance is responsible for the physical changes associated with aging along with the internal environment. Inefficiencies gradually increase the risk for illness because of the unstable internal environment. It has been seen where alleged negative feedback mechanisms become overwhelmed and destructive positive feedback mechanisms then take over. Negative feedback is mainly how homeostasis is maintained, and positive feedback includes processes like blood clotting (http://www.biology-online.org/biology-forum/about2004.html). In maintaining homeostasis, the kidneys, liver, and brain are the organs in which play an important role. The kidneys are responsible for controlling blood water level, and regulation of salt and ion content in the blood. The liver performs the function of stabilizing carbohydrate metabolism and metabolizing toxic substances (http://www.buzzle.com/articles/what-is-homeostasis.htm.l) Whereas, the brain helps in controlling the autonomic nervous system and the endocrine system. Dehydration, hypertension, diabetes, hypoglycemia, etc are major homeostatic imbalance health problems. Homeostasis is extremely important for proper functioning of all human body systems. Enzymes even need a specific constant temperature to work at their optimum level. At higher temperatures, the enzymes will stop working. Homeostasis occurs to all humans, animals, and plants and is needed for us to stay healthy and alive. There are different types of metabolic adaptations in fish. Temperature and blood pressure are two examples. Body temperature for a fish mainly depends on the temperature of the water that the fish is in. This is the same for a fish in a tank, lake, pond, river, ocean, etc. A fish body adjusts to the temperature where the fish will be comfortable in the water. Cold-blooded animals cannot generate their own body heat; they must regulate their body temperature by moving. Absorptive and post absorptive are two metabolic states. Digestion, strength, respiration, salt and water balance, and heart rate are also included in this category. Glycolysis is an anaerobic metabolic pathway. Homeostasis in fish as well as in humans adjusts when the environment that it is in adjusts. If a fish is swimming in polluted water, the water is going to affect the fish. Its going to affect the fishs vision, the fishs breathing, and many other things. Just like polluted air causes humans to get a disease or any other illness, a fish can get a disease or illness as well. The temperature will affect the pace of the fish similar to the temperature affecting the pace of humans. Homeostasis, in biological terms means that the body is maintaining internal equilibrium to adjust internally and physiologically, in response to the external environmental changes(http://www.buzzle.com/articles/what-is-homeostasis.html). The main function of homeostasis is to keep all the processes of the body stable even if there are variations in the weather and environment outside (http://www.buzzle.com/articles/what-is-homeostasis.html). Regulation of temperature is most definitely the most important aspect of homeostasis.

Materials- Two fish Small sized container/fish tank Hot water Cold water Room temperature water Notebook/paper Pen/pencil Thermometer timer Procedure- First, set aside a bowl of water to get it to be room temperature. While that sits, create a table with three rows and eight columns. Label the first row experimental sample. Label the next two rows fish one and fish two. Label the columns room temperature, number of breaths, cold water temperature, breaths, hot water temperature, and breaths. Then, get extremely cold water and pour it into the container/fish bowl. Take the first fish and put it in the container with the cold water. Take the thermometer and put it in the bowl of water; wait till the meter stops moving. Record the temperature of the water. Next, set your timer to sixty seconds. Start the timer and count how many breaths the fish takes until the timer goes off. Record the time. Take the fish and thermometer out of the water and pour the water out. Pour the hot water into the container/fish tank and put the previous fish back into the container. Take the thermometer and sit it in the bowl until the meter stops. Record the temperature. Like before, set the timer to sixty seconds and count how many breaths the fish takes in that time. Record your results. After that, take the fish out along with the thermometer. Empty the container of the water. By this time the water that was set aside should be room temperature. Take that water and empty it into the container/fish tank and put the previous fish and thermometer in the bowl. Record the temperature of the water. Set the timer and count the breaths taken again. Record your results before taking the fish and thermometer out. Pour out the water. Repeat this process with the other fish and new water.

What is the mechanism in which fish breathe in water? A fish is any cold-blooded vertebrate animal that lives in water (http://www.myuniversalfacts.com/2006/03/how-do-fish-breathe.html). Fish live in nearly any water habitat and can be found in many different varieties of climatic conditions from near-freezing Arctic waters to the hot desert springs. Animals that live on land have a different respiratory system from aquatic animals such as fish. A fish is capable of breathing under water without taking frequent trips to the surface to breathe air unlike a whale which is a marine animal. This is because fish have gills. It is a process to fish breathing. First, water in the fishs surrounding enters its mouth. Water enters the mouth by the operculum and a very effective pumping system that involves the mouth. As a fish pumps water through the gills it opens and closes its mouth. Water is drawn into the mouth after the fish opens its mouth and the operculum closes. After water enters the fishs mouth it passes through a structure. This structure is called gill rakers. The gill rakers act as a filter system by straining out particles such as food or any other foreign particles that may have entered the mouth from the inflow of water. Next, the filtered water travels through the gill arches hence passing over the gills. Projected out into the water flow allows water to flow across the lamellae are gill filaments. Resulting, oxygen and carbon dioxide are exchanged directly across the capillary membrane. As water flows through the gills, the dissolved oxygen passes into blood circulating through the gill structures. The gill structures include the filaments and lamellae. Simultaneously, carbon dioxide which is the waste product, in the fishs bloodstream passes into the water. It is then carried away and out of the body through the operculum. This is the process by which fish breathe also know as respiration.

America Needs The Death Penalty Essay example -- pro-capital punishmen

The death penalty has been a heated topic of debate for many of years. Some people believe that the death penalty is unconstitutional in that it is cruel and unusual punishment. Many people also think that the states do not have the authority to take a life. They think that it is god’s responsibility to judge life and death not mans. So they look at the death penalty from a religious view point. Items that this commission will consider in evaluating the humanity and constitutionality of the death penalty, are is lethal injection a humane way to put an offender to death. We will also consider the constitution to ensure the state follows the constitution. Further, consideration will be given to if the state ensuring that all death penalty offenders being given proper DNA testing to prove their guilt or innocence. One of the most important things that this commission needs to decide is whether the death penalty violates constitutional rights. Many people have claimed that the death penalty is unconstitutional because the death penalty is cruel and unusual punishment. An example of this is in California when the state delayed the date an inmate was sentenced to die because his lawyer said that the death penalty by lethal injection was cruel and unusual punishment (Hooper, 2006). Michael Morales’ (the man sentenced to death by lethal injection) lawyers state that there were cases with other inmates that did not receive enough anesthetic and therefore felt too much pain while being put to death (Hooper). This doubt raised can create a great concern for any state and that is why the governor has decided to hault executions and put this panel in place. A good portion of this cruel and unusual punishment will be explaine... ... Constitution. However, even though the death penalty is more costly, there are people that are simply too dangerous to remain alive. The death penalty also offers deterrence for people who may be considering an awful act. It may prevent someone from robbing a store because there is a chance someone could die in the act, therefore making it a capital punishment. There are pros and cons to the death penalty, but in the end I believe that it should be considered when dealing with the most serious and gruesome criminals. Works Cited Allen, H. E., Latessa, E.

The Holy Bible :: essays research papers

Our Children Children are the offspring born to a husband and wife in marriage relationship. To the Hebrews, children were considered gifts from God, and to be childless was considered a reproach; 'And after those days his wife Elisabeth conceived, and hid herself five months, saying, Thus hath the Lord dealt with me in the days wherein he looked on me, to take away my reproach among men'; (Luke 1:25). Jesus clearly expressed his love and respect for the children; 'And he took a child, and set him in the midst of them: and when he had taken him in his arms, he said unto them, Whosoever shall receive one of such children in my name, receiveth me: and whosoever shall receive me, receiveth not me, but him that sent me'; (Mark 9:36-37). How far have we strayed from the will of God? How many of us can would give anything close to the above definition if asked to define children. The culture is all around us but it should not be all in us. If our children were gifts from God in which we are to have an expressed love and respect, how would we raise our gifts? How many gifts would we ask of the Lord? Would we Plan our lives with as few gifts as possible so that we could spend more time building careers and acquiring worldly gain? Would we say when confronted with the culture's attitude on rejecting God's gifts, I would not reject God's gift but it is a personal choice? Who of us would say to those receiving a gift from God, I would cherish the gift from God but for I respect the rights of others? When the rights of other fly in the face of what God has said we must stand on the word of God and if need be take up our cross. Standing for righteousness will put us at odds with the culture. Being lights of Holiness in the darkness of this culture is exactly what Jesus was revealing when He spoke to the disciples; 'And he said to them all, If any man will come after me, let him deny himself, and take up his cross daily, and follow me'; (Luke 9:23).
