Orion Nebula - 1060 Words

The Orion Nebula contains one of the brightest star clusters in the night sky. With a magnitude of 4, this nebula is easily visible from the Northern Hemisphere during the winter months. It is surprising, therefore, that this region was not documented until 1610 by a French lawyer named Nicholas-Claude Fabri de Peiresc. On March 4, 1769, Charles Messier inducted the Orion Nebula, M42, into his list of stellar objects. Then, in 1771, Messier released his list of objects for its first publication in Memoires de lAcademie.1 The Orion Nebula is one of the closest stellar regions to the Earth. Using parallax measurements, it has been estimated that this nebula is only 1,500 light years away. In addition, the Orion Nebula is a†¦show more content†¦On April 9, 1998, Cornell University astrophysicist Martin Harwit published his discovery of the presence of massive amounts of water in the Orion Nebula. This was the first time that water has been found in a star-forming region. The find demonstrates that water plays a vital role in star formation. In addition, this discovery implies that water is prevalent in space. Harwit speculates that the water acts as a coolant, by carrying heat away from the condensing clouds. It is believed that this process is necessary to slow down the particles in order to allow the compression of the particles into new stars. 6 The discovery of water in the Orion Nebula will undoubtedly provide the basis for further study. More specifically, it will prompt scientists to search for water in other regions of space at different stages of star formation. Then, if water is present in each, it may suggest that the oceans of Earth are older than even the planet that now contains them. 7 Page 3 Several unresolved problems remain concerning the Orion Nebula. The fate of the protoplanetary disks, for example, is presently impossible to predict. Without a more detailed understanding of how planets actually form, it cannot be assum ed that the events within the Orion Nebula are analogous to the events that led to the formation of the planets in the solar system. Furthermore, the detection of water in the nebula has revealed the need to revise the theory of star formation toShow MoreRelatedInvestigating the History of the Universe and the Big Bang Theory674 Words   |  3 Pagescollapse along this direction.

Analysis Of Dulce Et Decorum Est By Wilfred Owen, And...

Man’s Inhumanity to man Introduction DULCE ET DECORUM EST by Wilfred Owen, and This Blinding Absence of Light by Tahar Ben Jelloun, are both powerful texts that give the reader sympathy and strong emotional experiences. When comparing the two texts, there are multiple aspects that they share, for example they both convey a strong message on survival and what it’s like to be faced with death, however the setting, symbolism and themes like hope, and the power of thought are very different. The novel This Blinding Absence of Light is set in the Tazmamart prison in Morocco, where Salim, a prisoner of war, was held captive with 18 other men for 20 years. When confined in a small, pitch black chamber, with only starchy food, sludgy water and what hope they have left, Salim and the men are pushed to their limits of survival under such harsh conditions. Throughout the novel Salim goes on both a mental and physical journey to come at peace with himself, which shapes his perspective of what life means. The text DULC E ET DECORUM EST is set in World War 1 when a group of British soldiers are attacked with chlorine gas. In the rush upon the shells of gas exploding, one soldier does not get his mask on in time. Wilfred Owen portrays in detail the gruesome effects of the gas upon this man and concludes that one may not have the same opinion after being exposed to the first-hand reality of war.

Workplace Ethical Dilema Free Essays

Ethical dilemmas can occur at any workplace. For this reason, codes of ethics are developed to help guide and set the standards for moral conduct for that profession. Code of ethics also helps establish procedures on how to deal with misconduct. We will write a custom essay sample on Workplace Ethical Dilema or any similar topic only for you Order Now While serving in the United States Navy, I came across several ethical dilemmas in my workplace. One dilemma that I remember clearly is one in which an officer (higher rank) and enlisted (lower rank) were involved in fraternization. Fraternization in the Navy is not acceptable and is referred to as a relationship between an enlisted and officer who are dating, who engage in intimate behavior, share a home, borrow money or gamble. Fraternization in the military can be punishable under the Uniform Code of Military Justice. On board the Navy ship there were approximately a total of 350 service members who were both men and women. Interaction between both sexes was inevitable; however two service members on board took it too far. There was a service member (enlisted male) who began to have a relationship with his boss (female officer). Both agreed to keep their relationship a secret while onboard the ship. One after noon I was out in town at a local store when I spotted both members holding hands together. I was not friends with either one, and did not say anything to them. I realized that their behavior was non ethical, but I did not want to be involved. Looking back at the situation my thoughts about it followed the principles of nonmaleficence. Nonmaleficence refers as doing no harm or mischief. I thought to myself that they were not causing harm to anyone therefore I did not want to report them. Through an ethical relativism view I realized that the dilemma was not morally wrong however, the situation in which they were engages did not follow the ethical standards of the workplace. However my view about the whole situation changed when I talked about it with another co-worker and she informed me that the female officer was married. The fact that she was married completely changed my perspective about the situation. Now, not only was it ethically wrong but it was morally wrong too. At this point the dilemma then interfered with my personal values. My personal values are may not be the same to the ones of others; however the choices they made went against my beliefs and values. Growing up I was always taught that fidelity and commitment to your partner is very important. I put myself in the spouse’s shoes and realized I would never want to go through that. The behaviors the engaged were bothersome and I felt very uncomfortable around them. I can relate this dilemma to the thoughts of Socrates, that no one voluntarily does evil when they know good. If evil is done is because there is some type of benefit within for that person committing evil. The officer in this case is aware of the evil she is committing, however she is gaining comfort, perhaps love, or pleasure from her behavior with the enlisted male. Both personnel practiced ethical egoism, due to fact that they only care about their happiness and did not care about those who got hurt. This is when I realized that I needed to speak up about this dilemma. In order to resolve this dilemma I needed to speak up and report what I knew and saw to my higher chain of command. I would have to say that I applied the theory of Kant. Good will and motivation was the base of my decision to report the dilemma. I knew that making this decision was going to bring bad consequences for both members, however I did what I thought was best. In my decision making process with the Kantian approach, ethical decisions were based on my sense of duty. The word duty is derived from the Greek word deon (deontological). Duty refers to the acts of a person based on the principles of morality. In this decision making approach I had to make decisions based on what is right rather than the good or bad consequences that will follow. A person must make the morally right decision regardless of the good or bad outcome. Categorical imperative is what determines whether an act is morally right or wrong. The requirements of categorical imperatives are that moral principles are applied by respecting humanity. In this deontological point of view a person should act rational person and make self-imposed decisions. After reporting the situation to the chain of command, I was asked to speak up and testify along with others who had observed the same behaviors. Both services members were punished by the UCMJ and forced out of the military. The consequences to their behavior are what constitute it to be wrong. The ethical dilemma went against my personal values and belief. This is why I decided to speak up and report what I knew regardless of the consequences. Both members were aware of the good and evil and instead decided to go for the evil not that they could hurt others. This ethical dilemma not only affected them in a personal level but affected the work place as well. After all the consequences, sailors onboard are very careful about fraternization. Workplace ethical dilemmas can happen at any work place, therefore it is important to maintain an updated code of ethics. This will help and guide employees on procedures , employee conduct and misconduct consequences. How to cite Workplace Ethical Dilema, Essay examples

Lincon vs Kennedy Essay Example For Students

Lincon vs Kennedy Essay Many people share similar aspects throughout their lives, but could two significantly relevant people shared such common lives that might even seem eerie. Abraham Lincon and John F. Kennedy were both assassinated. However, apparently there is more to connect them than that. A little part of US history makes you wonder if it is mere coincidence, or maybe planned? Where it all began, Abraham Lincoln was elected to Congress in 1846. John F. Kennedy was elected to Congress in 1946. Whereas Abraham Lincoln was elected President in 1860; John F. Kennedy was elected President in 1960. The names Lincoln and Kennedy each contain seven letters. Both were particularly concerned with civil rights. During their political lives in Washington, D.C., Lincon and Kennedy and their wives lost their children while living in the White House.Seemingly, both Presidents were shot on a Friday, in the head. A very unbelievable fact was that Lincolns secretary was named Kennedy, and Kennedys secretary was named Lincoln!Both were assassinated by Southerners, and were succeeded by Southerners with leaders named Johnson. Andrew Johnson, who succeeded Lincoln, was born in 1808. Lyndon Johnson, who succeeded Kennedy, was born in 1908. Another very significant aspect between Lincon and Kennedy was their assassination. John Wilkes Booth was born in 1839. Lee Harvey Oswald was born in 1939. Both assassins were known by their three names. Both names are comprised of fifteen letters. (Booth ran from the theater and was caught in a warehouse. Oswald ran from a warehouse and was caught in a theater.) However, Booth and Oswald were assassinated before their trials. The life of Abraham Lincon was different from that of John F. Kennedy, or was it? Although two significantly distinct figures in American History lived during two completely different centuries, eventually many facts were brought about that almost were exact. Bibliography:

Reality TV shows argument free essay sample

When you consider other types of television shows, like talk shows for example, the popularity of reality TV isn’t all that surprising. It seems that people simply enjoy watching other people perform various activities. Television networks realize this; therefore the number of reality shows has grown considerably in the last few years. Unfortunately, this type of programming has turned into something more than harmless entertainment. Reality television shows do not depict true reality because they are scripted, they overdramatize events, and they cannot capture the truth when people are in front of the camera. But do viewers care if their shows have been, say, artificially enhanced? Reality TV is a misnomer because much of the action and dialogue is actually scripted or controlled by the producers. Reality TV is a much manipulated format where the basis of it is that real people are put into unreal situations to create a story. We will write a custom essay sample on Reality TV shows argument or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page As soon as they get into an unreal situation, one could argue that it’s scripted, because the situation is created by the producers. The television music competition show, ‘The X Factor’, is supposed to be unscripted, but certain documents have revealed that the show follows an Australian production Bible which has the scripts of main aspects of this television series. A source involved with the show revealed that some on-screen events are manipulated in the post-production. Thus the show is scripted. This is well related to ‘American Idol’, where previously unknown individuals are meant to audition in front of unscripted judges, little do the viewer’s know, much of the conversation and judgment was previously planned. â€Å"Call it ‘partially scripted television’, says Ray Richmond. The longtime television critic who now blogs about entertainment and pop culture, said he has been trying – so far unsuccessfully—to have the term â€Å"reality television† switched to â€Å"partially scripted television. † Often, reality TV shows are meticulous in a sense of being highly overdramatic. Cameras document actual events of ordinary people or celebrities and overdramatize everyday situations. Producers of reality TV shows will hire actors and have them reenact and overdramatize events about themselves; therefore the events shown in the show were fraudulent and exaggerated. When exposed to an exaggeration or fabrication about certain real-life occurrences or facts, some people will perceive the fictional account as being truer than any factual account. This might lead to people acting on preconceptions about unfamiliar matters even in a life-or-death situation or cause viewers to cry foul when things on a show work out in a way that actually is realistic, but contrary to what everybody knows†, like complaining of the fake English accent of a real English actor or about a characters death from a bullet merely to the shoulder—suggesting that viewers often react in a dramatic way to situations that aren’t as tragic or breathtaking as they are perceived, simply because the producers intended to make that situation seem to be more emotional than it genuinely was. Reality shows invariably fail to capture the truth when people are in front of the camera. The show ‘Jersey Shore’ is an adequate representation of how editors and producers depict false situations of people in front of the camera. The show is simply young individuals being put on television, and being told what to do, how to do it, and what to say—they’re not being themselves. Ray Richmond informs viewers that, â€Å"The editors have grown to become the new storytellers, altering sequences and the course of events and contextual elements to weave together a story that’s radically different from what actually happened. † Ultimately when directors participate in doing this, it not only makes for a product that’s mislabeled, but also disingenuous and deceptive. Reality TV often succeeds in capturing and holding on to Americans attention because it allows them to fantasize about gaining status through automatic fame. Ordinary people can watch the shows, see people like themselves and imagine that they too could become celebrities by being on television. It does not matter as much that the contestants often are shown in an unfavorable light; the fact that millions of Americans are paying attention means that the contestants are important. And, in fact, some of the contestants have capitalized on their short-term celebrity: Colleen Haskell, from the first Survivor series, has a major role in the movie The Animal, and Richard Hatch, the scheming contestant who won the game, has been hired to host his own game show. If these former nobodies can become stars, then who couldnt? The message of reality television is that ordinary people can become so important that millions will watch them. And the secret thrill of many of those viewers is the thought that perhaps next time; the new celebrities might be them. An example would be ‘Duck Dynasty’; a show where normal people have their own television show for living their everyday life. Watching the show, you would say that they don’t have to act a certain way or say certain things because they are simply performing their daily routine around familiar people, which are there off the TV screen. But do you really know these people? How do you know they don’t act differently off the camera, in their everyday life? You don’t. Therefore, no one can truly say that these shows are one hundred percent accurate. By now we’re all well aware that most reality TV is anything but a reflection of reality, simply because it is often times scripted, it is highly overdramatized, and it cannot depict true images to the viewers. Reality TV shows may seem like a true depiction of reality and a harmless entertainment, but it does have deficiencies that people may not notice while they’re watching. It’s safe to say that artificiality is the new reality.

Social Welfare Influences

Social Welfare Influences In any modern organisation, the existence of social welfare is paramount. Social welfare is in man’s nature. Social welfare is about how people and societal institutions seek to provide set basic standards as well as certain minimum opportunities for its people. It is about the quality of life that affects access to essential social services.

Man cannot survive on his own and therefore forms associations with others to ensure continuity of his species. In the primitive society, traditions and customs played a major role to ensure that family ties are maintained in order to ensure cooperation for the collective needs of the society. In today’s modern society such ties are slowly fading away and the society has put in institutions of governance to achieve the same. Society through institutions in government has laid down the necessary machinery including institutions of public finance to achieve that. Under such initiatives social services such as provision of medical services, security, Public health, provision of education, child welfare, provision of education and so on. It is therefore the role of the state government to ensure that the economic as well as the social well being of all its subjects. This is premised on the principle of equitable distribution of resources in society, equal opportunities for all as well as taking responsibility for those individuals who are unable to provide the basic minimum for themselves.

This has lead to the constant pull and push between the haves and the have not’s, the employer and his employees , the bourgeoisie and the proletariat and so on in an effort of each individual guarantying their own personal wellbeing. In the past many considered social welfare as a private concern but in today’s modern world social welfare cuts across all divides of society and has found its place in public debates. Social welfare is largely affected by global trends such as globalization. Another issue that affects social welfare too is a states aging population as well as a state decline in fertility rates. The above concerns present a challenge to state economies that continue to sustain social welfare programmes. As a trend that affects the world over Globalisation is one that o state can ignore. Any economy that would still like to compete in the global market with other states that do not have to incur the burden of social spending tax. In order to continue sustaining their economies and supporting viable projects such states must completely eliminate all social commitments. In many industrial nations their population is aging therefore most of the social welfare programs are catered for the aged. Since the aged are the majority of the population the burden is then placed on the minority population. To sustain such a burden can be an enormous task for the minority population to sustain. Industrial nations have undergone sharp declines in population growth as well as fertility rates. Very few economies such as that of the United States have maintained their replacement rates. The result of such a trend is disastrous in terms of providing support for social welfare programs

Competition-MicroEconomics Term Paper Example | Topics and Well Written Essays - 1750 words

Competition-MicroEconomics - Term Paper Example A large number of firms, product differentiation and easy entry and exit are the main characteristics of monopolistic competition. Competition is one of the important market forces. There are mainly two types of competition exist: price competition and non-price competition. Price competition is mainly experienced in a highly competitive market where perfect competition takes place. On the other hand, non-price competition occurs mostly in monopolistic market situations in which competing firms offer different attractive offers and special discounts with an aim of attracting and retaining customers. Competition provides an environment in which not only buyers benefit but also sellers enjoy normal profits. For the buyers, competition is a source to obtain reasonable but competitive prices for goods and services and they do not need pay additional charges for the goods and services. This mostly occurs in perfectly competitive market in which buyers have perfect information about the goods and services and homogenous products are sold. Monopoly is form of market structure in which there is only a single seller who controls the entire supply of goods or services. Monopolistic competition is a combination of both perfect competition and monopoly. In which, there are certain characteristics of both monopoly and perfect competition remain functional. In the following parts of the paper, first definition of competition has been provided and it is followed by types of competition. After defining each type of competition, a conclusion part has been included to sum up the paper. Firms observe two types of competition: price competition and non-price competition. The firms compete with each other to attract and retain customers. For this purpose, they adopt different competition strategies to entertain their business objectives. Diminishing the price of their product below the price of competitors is one way to increase
