Dopamine, It Does a Body Good :: Biology Essays Research Papers

Dopamine, It Does a Body Good In class we have frequently discussed the I-function and how it relates to the body and the brain. Is the I-function a separate soul? Is it simply an extension of our DNA and genes? In addition, we have fretted over the I-function and its relationship to our behavior or personality. Where exactly the I-function is, we have also wondered. In this paper I will explore personality, the I-function and their relationship to genes and chemical changes that take place within the body. I will mainly look at how neurotransmitters affect overall happiness in an individual. How these chemicals are regulated by genes and by the environment, will also be questioned. Overall I will look at what makes us who we are. Are we simply programmed for life by our genes or do they even matter at all? While searching the web I found many good articles which explained how neurotransmitters affect personality. In some cases norepinepherin can encourage quick emotional responses like anger and also discourage logical thinking, while serotonin can cause irritability and a lack of rational emotion. All of them can cause anger, anxiety, depression, insecure feelings, and fear. To find out what the characteristics of personality are, I found another site appropriate. It lists 16 types of personality that are controlled by various combinations of 4 dimensions: extrovert vs. introvert, sensor vs. intuitive, thinker vs. feeler, and judger vs. perceiver. You can see how some of these could be determined by neurotransmitters. With happiness in particular, a group of psychologists describe it through the set-point idea. The set-point idea contends that there is a genetically determined mood level that can be nudged by life slightly upward or downward, but in the long run will stay about the same for each individual. Therefore, if you win the lottery or become a paraplegic, you will remain close to the same happiness level that you were always at. The 2 doctors say that about half of your sense of well being is determined by your set-point while the other by the sorrows and pleasures of life. By studying the activity in each prefrontal area, happiness and enthusiasm can be detected from worry and agitation. They tested 10 month old babies and then tracked them for several years and still found the measurements of their brain-wave patterns accurate. It was also discovered that an allele for part of the D4 receptor were related to the amount of

I Never Sang for my Father Essays -- essays papers

I Never Sang for my Father The father son relationship is very important. A growing boy needs a strong fatherly presence in order to become a â€Å"man†. The plays, â€Å"I Never Sang for my Father,† and â€Å"The Owl Killer,† and the short story â€Å"Notes to a Native Son,† show this. The lack of communication and basic affection from their fathers directly affected the sons’ mental health, including self-esteem. The father in â€Å"I Never Sang For My Father,† Tom, was very mentally and physically abusive. Many times during the story he acted very self-centered. He was once a politician and loved it very much. The relationship with his son, Gene, was not a good one. Due to Tom’s abuse early in life, he and Gene were never able to have a positive relationship. Gene also was never able to really stand up to his father. Probably due to a fear of him he had developed early in life. Even with this fear, Gene proved to be not be too damaged by his abusive childhood. I believe that his low self-etheme came from this upbringing. Still he had a kind of respect for his father because he...

Oscar Hammerstein II †Lyricist, Writer, Producer, Director Essay

Oscar Hammerstein II was born July 12, 1895 in New York, New York. He died August 23, 1960 in Doylestown, Pennsylvania of stomach cancer. His given name was Oscar Greeley Clendenning Hammerstein. When he entered the theatre profession, he dropped his middle names and adopted the â€Å"II† from the grandfather for which he was named. His grandfather was a theatre builder and opera company producer. By titling himself â€Å"II† he capitalized on his grandfather’s success; the name recognition alone was a career builder. Hammerstein was always interested in the theatre. His father, although a theatrical producer himself, did not want his son to go into the â€Å"family business†. He made him promise â€Å"never to do anything as foolish as to consider making the theatre your livelihood. Become a lawyer. You’d be great at it and it’s also one of the more secure professions I know of.† â€Å"Getting to Know Him – Biography of Oscar Hammerstein II† Hugh Fordin As per his father’s wish, Hammerstein entered Columbia University as an English major. He was an honor student and was involved in many extra-curricular activities; one of which was the Varsity Show. This was where Hammerstein met Larry Hart and the man with whom he would later collaborate, Richard Rodgers. At the time of the initial meeting, Rodgers was only a fourteen year old boy whose older brother Morty was a member of Hammerstein’s fraternity. Although his father had passed away, Hammerstein felt compelled to honor his father’s wishes and entered Columbia law school. He finished his Bachelor’s degree during his first year of law school. During his second year of law school, Hammerstein was so disenchanted with the law he asked his uncle Arthur, a successful producer of musical comedies, for a job. He was hired as an assistant stage manager. After witnessing his nephew’s theatrical ability, Uncle Arthur hired him as a permanent member of the staff. Soon after having been hired by his uncle, he began an apprenticeship with Otto Harbach. What began as an apprenticeship turned into a twenty year collaboration and produced Hammerstein’s first Broadway success Always You. Over the course of his career Hammerstein would collaborate with many different composers notably, Jerome Kern, Vincent Youmans, Rudolf Friml and Sigmund Romberg. Hammerstein’s most successful collaboration would be with the man he had met during his varsity show days at Columbia University, Richard Rodgers. The collaboration with Richard Rodgers began in the early 1940’s with their adaptation of the play Green Grow the Lilacs. This became Oklahoma! and changed Broadway forever. Oklahoma! revolutionized the Broadway theater by integrating the music and book. Previously only Show Boat and Pal Joey, respectively a Hammerstein and a Rodgers production, had used songs to further the story along. Oklahoma! not only used the songs as an integral part of the story but it also incorporated American ballet. The opening was different – only one person on stage with an offstage voice singing as the curtain opened. The female chorus didn’t appear until 45 minutes into the play. The â€Å"chorus† girls where covered in period dress. There were no â€Å"star vehicle† numbers. No song in this musical play was written to become a popular hit. Oklahoma! changed the American musical theatre and gave Hammerstein, who had been battling a career slump, a new burst of energy for the most successful period of his career.

Nuclear and Coal Power: Which is Better

Today we are living in a world that is becoming increasingly more environmentally conscious, yet consuming more energy than ever. Having such high-energy demands creates many environmental issues, such as pollution, land exploitation, and the consumption of finite resources. In order to begin a true conservationalist society, solutions must be found that satisfy our growing energy needs, and reduce our impact on the environment. Right now we have many sources of energy, of which nuclear and coal are the predominant energy sources of today. Since these are the major energy sources a logical step in the solution process is discovering the pros and cons of each source. Coal energy is very inexpensive and easy to recover, and accounts for approximately 40% of electric energy produced worldwide, down from 74% in 1937. In order to derive energy coal must first be mined, then transported to another location where the coal will be burned, which results in the release of toxic pollutants into the atmosphere. Coal energy is a significant contributor to both global warming and acid rain because of its high carbon and sulfur content. There also exist the harmful effects of both mining for the coal and of transporting the bulky product. There are several ways to mine for coal, the most significant of which are strip mining, and underground mining. Strip mining, as the name implies, requires massive amounts of soil be removed in order to expose the coal. Such actions leave enormous scars on the earth and require years for reclamation to occur. The eyesores created by mining underground are not as large however, the perils of underground mining have claimed hundreds if not thousands of miners lives in both accidents and diseases brought on by the extreme exposure to coal products. Then comes the extremely expensive task of transporting the coal from the mining sites to locations all around the world. Because of the bulky nature of coal, it requires a massive transportation system, which itself uses other fuels further contributing to the pollution problem. There seems to be little hope of decreasing the size of this operation, since it is entirely dependant upon the physical characteristics of the coal itself. Nuclear energy is the most concentrated source of energy currently available for use. The fuel to drive nuclear energy is also inexpensive, and nuclear energy creates the most compact waste of all the different types of energy. The major steps in the nuclear fuel cycle are as follows: 1. Mining of the ore; the danger of radiation exposures was long ignored however, the advancement of our knowledge of radioactivity has greatly reduced the risks involved with the mining process. 2.Milling; waste accounts for 99% of the resulting in great accumulations of mine tailings that have to be stored somewhere, the removal and storage of tailings still presents a problem. 5.Fuel Fabrication; once converted and enriched, the fuel is formed into ceramic balls and placed inside a tube, thus becoming a fuel rod. 6.Fuel Reprocessing; After the fuel rod is used up, it is placed underwater and stored for up to a year, after which the rod is disassembled and some of the leftover materials are reused in the enrichment phase. 7.Waste Management; Radioactive waste can have half-lives of tens of thousands of years, long-term solutions are needed. As of today waste in a concentrated liquid form is put in temporary depositories, with the hope of someday solidifying the waste so it can be stored for the long-term. From these steps, one can see the basic processes required for nuclear energy to occur. The extreme amounts of tailings present a huge hurdle to overcome, researchers are currently searching for new methods to obtain the ore, which are both less wasteful and cost efficient. However, one large benefit of nuclear energy is the ease of recycling many of the nuclear core wastes. There are no greenhouse or acid rain effects caused by the use of nuclear energy and the process itself has been thoroughly developed and understood by scientists. As with coal nuclear energy also has its drawbacks. First, nuclear plants are very expensive and require large amounts of capital before building can take place. Secondly, although the waste is very compact, the waste is also highly hazardous to the environment. And lastly there is the issue of nuclear meltdown, which is detrimental to life and the environment. This last issue of meltdown or other possible cases of public exposure is the single largest factor limiting further implementation of nuclear power around the world. People assume that nuclear energy is extremely unstable, when it is actually extremely stable. Coal power is much more hazardous than nuclear power, but people seem to be unwilling to accept nuclear energy and continue to use less safe coal energy. The transportation of nuclear energy is extremely safe. â€Å"No activity in the history of technology has as good a safety record and is accomplished with as little risk as the transportation of nuclear material.† Knowing such a fact as this might begin to persuade those who doubt the safety of nuclear energy, and possibly embrace this technology. With this brief look into the environmental crisis that human†s high energy needs have created, it is important for us to find a suitable solution that appeases our energy needs without destroying the environment any more. It is necessary to gauge the benefits against the risks of all of our energy sources, and determine which ones best suit our needs and the needs of the planet. We can no longer be an uneducated public, for the power governing which sources of energy are used ultimately lie in the hands of the public. Fear of what we do not understand is not the way to decide, people need to take the initiative to discover for themselves what is best for them, and more importantly what is best for the environment.

It does take long to conceptualize the image-especially in terms of theme and the target audience. The background and the respective contents of the images help in contextualizing the contents and the theme of the images and this can be realized immediately you see the images. The Tag Body Spray ad is very lively while the Japanese Silkscreen painting is dull-in regards to images coloring. Generally, the difference in temporalities between these two images is based on the fact that the Tag Body Spray ad is a photo image while the Japanese Silkscreen image is a painting image. Crow considers Warhol to be three in one person. The first Warhol is attributed to his life; the 2nd is in relation to his complex of interests, skills, sentiments passions and passion for art while the 3rd is attributed to experiments in nonelite culture far beyond the world of art. According to Crow, the works of Warhol were characterized by the impersonality of the images he chose and their presentation, the suspension in his work of any clear authorial voice and the passivity in the face of a media-saturated reality (Thomas, 5). The success of Warhol was highly increased by the fact that he was able to control the interpretation of his own work. Crow main argument was that Warhol produced his most powerful work through dramatization of the breakdown of commodity exchange despite the fact that his art was based on the ubiquity of the packaged commodity. In this essay, Crow tries to understand the works of Warhol and how he developed his paintings. According to Crow, Warhol used his painting works to send-out different messages. The paintings of Warhol were for different seasons, for political reasons, community based and socio-economic in nature (Thomas, 9). For instance, Crow argued that Warhol painted the image of Elizabeth Taylor to

Media Law and Ethics Essay Example | Topics and Well Written Essays - 1500 words

Media Law and Ethics - Essay Example Newspapers are among the most affected modes of communication in modern times that have been adversely affected by the debates and the differing viewpoints taken by stakeholders in the freedom debates (Barendt, 2009). While some support an entirely free press, a cross section of society feels that such freedom should be regulated to some extent. That is, laws should be enacted to ensure that media houses, more so newspaper publishers are regulated so that they do not exceed certain limits that could endanger personal and public safety or engross on human rights and liberties. Those in support of total newspaper freedom assert that this absolute freedom must be sought through constitutional and legal protections although the norm is that there should be zero interference in the media freedom from overreaching state and regulatory agencies (Dean, 2011). However, the supporters of newspaper freedom concur with their opponents who feel that with regards to government information, certain critical information, classified as secret and sensitive due to their national interest and security roles should be protected from disclosure to the public. Newspaper publishers should therefore acknowledge that certain information must be controlled and secretly guarded for the sake of protecting the interests and safety of a state. Newspapers should be Free As a result of the sensitive and controversial nature of press/newspaper freedom, governments have established not only laws and agencies to execute certain press freedom-related tasks but also commissions of inquiry to look into specific events related to press freedom. In the UK, one such commission was the Leveson Inquiry, which Prime Minister David Cameron appointed on July 6, 2011 in accordance with the Inquiries Act 2005 to further investigate the cultural and ethical practices related to the revelations of phone hacking activities by the News International. The News International phone-hacking scandal is a controversy surrounding the defunct News of the World and other media outlets related to the subsidiary of News Corporation, News International. In this phone-hacking scandal, the employees of these related firms have been accused of engaging in police bribery, phone hacking and improper influence in executing their tasks of collecting information and creating stories. The public outcry was particularly targeted at News Corporation’s owner Rupert Murdoch whose company was accused of targeting celebrities, high-profile cases, victims, the British Royal Family and bombing victims in their phone hacking activities. Because of the resultant advertiser boycotts, the News of the World closed on 10 July after publishing for 168 years and the News Corporation cancelled its intended takeover of the British telecommunications company BSkyB (The BBC, 2011). The Lord Justice Leveson-led inquiry was thus mandated to inquire about these claims about the News of the World. Further, the Inquiry had to l ook into the initial police inquiry and the allegations that the News Corporation made illegal payments to police (Jenkins, 2012). The most important role of the Inquiry was however to review the UK media’s general culture and ethics. From this case study, it is imperative that media stakeholders recognize their role, responsibilities and influences in the society to act not only ethically but

Accounting Research - Essay Example The mortgage-backed securities were discovered held in portfolios in banks and hedged in funds all over the world. This greatly affected the other commercial instruments. The stock in the US fell around 13% in fears of collapse of these banks. Investors soon withdrew their money from these banks which led to liquidity problems for the banks. In three days’ time customers had drawn  £2 billion. The crisis spread fast to investment funds and management funds that had been exposed to subprime debt. Most of the funds lost value of their assets e.g. Global Alpha hedge Fund lost 26% value; while others stopped valuing their funds due to complete evaporation of liquidity. With attempts by the Federal Reserve to stem the crisis by imputing more money into lending institutions and with the aim of gaining investor confidence, 2008 saw a complete turn of events. Loss of investor confidence in financial institutions spread to credit markets. A decline by 30% prices of market prices for commercial papers was felt. Fair value has been defined as that price which would be received to sell an asset or paid to transfer a liability in an orderly transaction between the participants in the market at the measurement date (Laux, 827). The second level input was for direct or indirect observable market data which could be used to value assets with no observable prices. Market information was used to give the mark-to-model measurements (Healy, 6) Lastly the third level of inputs that entailed unobservable firm supplied estimates e.g. home price depreciation forecasts, resultant credit loss severity on mortgage related position et cetera (Healy, 7). The application of the FVA resulted in many financial institutions making huge write downs that eventually led to the subprime crisis. Level 2 and 3 inputs had to thorough explained. The
