Humans do not seem to be comfortable with someone who has a different opinion and different views from them. Throughout the history of the word discrimination has been seen everywhere. Barbara Jordan says that â€Å"we as humans must be willing to accept and tolerate people who are different from ourselves. â€Å" We must tolerate everyone because they have the right to express their opinion. Intolerance has happened all across the globe, it has happened in the past and it is still an ongoing problem many people face.

In 1961 a group of people known as the freedom riders set out to the Deep South in order to defy the Jim Crow laws that made segregation legal and prohibited white and colored people from being together in the same restaurant. Train stations had white waiting areas and colored waiting areas. The freedom riders were calling for change; they were often imprisoned for disturbing the peace. The freedom riders movement was spreading across the country.

Essay about Oedipus Rex and Fight Club - 965 Words

Oedipus Rex, a play written by Sophocles, and Fight Club, a movie directed by David Fincher, are two stories that relate to one another by sharing similar ideas and life lessons. One could argue that both contain essential qualities and characteristics of classical tragedy, but are they both ultimately tragic in the classical sense of the word? I believe that both Oedipus Rex and Fight Club do, in fact, exhibit the important qualities of classical tragedy but ultimately, I think that only one of the two stories is a true classical tragedy. The term ‘classical tragedy’ may often be confused with the modern view of tragedy. Today, we may think of a tragedy as a disastrous event such as a car accident or a natural disaster, often leading†¦show more content†¦Therefore, this ending is an example of a sorrowful and disastrous conclusion. Sorrow and disaster are also central in Fight Club, in which a depressed young man, named in the credits only as Narrator, doesnt l ike his work and gets no sense of reward from it. Instead, he attempts to drown his sorrows by putting together the perfect apartment. He cannot sleep and begins to feel alienated from the world at large; hes become so desperate to relate to others that hes taken to visiting support groups for patients with terminal diseases so that he will have people to talk to and cry with. One day on a business flight, he discovers Tyler Durden, a charming, free-spirited man who sells soap. Tyler couldnt care less about the materialistic world, and he believes that one can learn a great deal through pain, misfortune, and chaos. One night, after the narrator comes home he finds his apartment burnt to the ground and he ends up spending the rest of his night at a bar with Tyler. After leaving the bar, Tyler cheerfully challenges his new friend to a fight.

The Career of Nursing - 1259 Words

According to Boykin â€Å"Caring is the foundation of nursing† (Boykin et al, 2011) and in order to be a nurse, it is essential that a nurse can demonstrate and practice professional communication skills. Professional communication skills not only allows the nurse to provide different methods and tactics to communicate with patients of different needs and ages, but it enables the nurse to understand and to give the best possible care and outcome for the patient. Provision of information and handover is another major point for nurses and relates to professional communication. Nurses need to be able to get a detailed diagnosis from the patient through communication, and therefore allows for the nurse to handover vital information to other doctors or nurses who take over to provide the correct and best possible treatments and care. The nursing profession requires a nurse to uphold professional communication, provision of information and handover in order to care for the patient w ith the right treatment, and to provide the best health outcome. It is the nurses’ responsibility to understand what it means to have professional communication skills. Not only does not being able to communicate affect the patient, but also it affects how the nurse is able to do his or her job to the best they can.

An Examination of Two Sides of a Controversy Free Essays

One that might make your hair rise, scream with all your might or run very fast is the sight of a human skull and skeleton during a full moon in an old abandoned house. This is the usual scene in a horror movie. Indeed, people fear seeing human remains. We will write a custom essay sample on An Examination of Two Sides of a Controversy or any similar topic only for you Order Now But skeletal remains can also cause conflict between museum owners, scientists and tribal groups. Authorities are usually torn between legal wrangling of these groups each one claiming the remains’ ownership. Nations of the world are also locked in debates over cultural property rights and intellectual property rights. The dispute between two great nations over great artifacts also has some repercussion on the economy of these two countries. Almost all schools and universities in the world maintain a museum basically for their activities in arts and sciences. In here, actual samples or replicas of the past are stored and lessons are becoming interesting if students can readily see what they read in the books. The more interesting the contents of the museums, the more famous they become. This generates sense of pride for the institution and sometimes become a source of revenues too. This is the reason why museums are trying to acquire interesting objects and when they become part of the museum, the real owner of the object finds it difficult to claim it. This becomes the source of conflict between museum administrator and Native Americans in the case of ancient artifacts. Archaeologists too are hard bent on keeping them because they are prized possessions and scientists can discover various things from studying the object and contribute to the enhancement of science. One afternoon of a windy Sunday, more than ten years ago, while seeing hydroplane race, along the shores of the Columbia River, two students found human skull that was washed into the shore. An almost complete skeleton was also found in the place. Study conducted on the remains has yielded information that the skull is already 9,400 years old. A conflict ensued immediately among scientists, Native Americans including local authorities (Ainsworth 2000). In Honolulu, Hawaii, artifacts were borrowed from a museum but apparently, the group who borrowed failed to return the remains and refused to reveal the whereabouts of the Native Hawaiian artifacts. This led to the filing of contempt of court by the federal judge against four heads of a Hawaiian gang. The four are members of the group called Group Caring for the Ancestors of Hawaii. Members of the group claimed that the artifacts were removed from its original place by an archaeologist and illegally offered for sale to the Museum. Group members assert that they just return the artifacts to where they rightly belong (New York Times 2005). An archaeology student recovered bones, beads and pieces of shells in Dry Lake Cave at the southern tip of Owens Valley in 1950. She wrote her findings in her record notebook. More than 50 years later, while her artifacts together with her records are lying inside a stockroom in Hershey Hall, three elders of the tribal group Timbisha Shoshone of Death Valley carefully inspect artifacts trying to see objects with cultural value, which they feel are rightfully theirs. The land of their ancestors includes the Dry Lake Cave (Lee 2002). Pauline Estevez, a tribal leader, who had an invitation to visit UCLA from the Fowler Museum of Cultural History, remarked, â€Å"It is our obligation as Indian people to safeguard our land and its wealth, Some of the artifacts here are part of our treasures which we think should not be kept by the museum or its collector because the land is their rightful owner† (Lee 2002). That is the reason why Estevez took the opportunity to yield to the invitation of the Fowler Museum of Cultural History. As an elder of a tribal group, she feels that what belongs to her land should be returned because they are part of their culture. The artifacts can be their ancestors or the treasures they brought with them which witnessed the birth of their tribe. They take pride in those artifacts and should also be seen by the younger generations as part of their identity. The Kennewick man who was found in the shore of the Columbian river was supposed to be returned to the five American Indian Tribes who jointly filed a claim so that they can possess and rebury the remains that they believe are theirs. The claim was under the Native American Graves Protection and Repatriation Act of 1990. The natives might have the same motive as those inhabitants of Death Valley. What belongs to them should be returned so that the remains of their ancestors can reunite with their land and the community where they once belong. The natives feel that their ancestors will be more peaceful going back to where they belong rather than to remain in the cold museum (Ainsworth 2000). That could be the same motive that prompts leaders of the Hawaiian group not to return the artifacts that were borrowed from the Hawaiian museum. They asserted that since those artifacts were taken illegally from their original burial place, they should be returned there so that the souls of their ancestor will really lie in peace. Meanwhile, a group of angry archaeologists who are interested in the Kennewick man want to study the remains. The finding of a 9,400 year old artifact naturally will interest them. They protested the move that will give the natives the right to the ownership of the Kennewick man. That started the legal battle between the archaeologists and the Confederated Tribes of the Umatilla Indian Reservation (Ainsworth 2000). While the natives are fighting for the return of the remains so that it can once again be a part of the original community and peacefully lie there, the scientists are hoping that they can contribute significantly to the world of science if they can study the remains. They believe that they can learn from the past as a way of improving the future. Thomas spoke in a crowded Kroeber Hall and states that the significant issue about the Kennewick remains are neither about religion nor science. According to him the issue is with regards to politics and not philosophy, about leadership and power. The question of who calls the shot when it comes to ancient American history. Is it the federal, the science community or the American Indian? Thomas is a vocal advocate of cooperative partnership between the American Indians and the scientists. He maintained that in a case like the Kennewick man, it’s a long and bitter fight, which can reach the Supreme Court. He believes that this case can be settled away from the premises of the court (Ainsworth 2000). How to cite An Examination of Two Sides of a Controversy, Papers

THE STRATOSPHERESubject: 1.1) What is the stratosphere?The stratosphere extends from about 15 km to 50 km. In thestratosphere temperature _increases_ with altitude, due to theabsorption of UV light by oxygen and ozone. This creates a globalinversion layer which impedes vertical motion into and within the stratosphere since warmer air lies above colder air, convectionis inhibited. The word s tratosphere is related to the wordstratification or layering. The stratosphere is often compared to the troposphere, which isthe atmosphere below about 15 km. The boundary called the tropopause between these regions is quite sharp, but itsprecise location varies between ~9 and ~18 km, depending upon latitude and season. The prefix tropo refers to change: the troposphere is the part of the atmosphere in which weather occurs. This results in rapid mixing of tropospheric air. Above the stratosphere lie the mesosphere, ranging from ~50 to~100 km, in which temperature decreases with altitude; the thermosphere, ~100-400 km, in which temperature increaseswith altitude again, and the exosphere, beyond ~400 km, whichfades into the background of interplanetary space. In the uppermesosphere and thermosphere electrons and ions are abundant, sothese regions are also referred to as the ionosphere. In technicalliterature the term lower atmosphere is synonymous with thetroposphere, middle atmosphere refers to the stratosphereand mesosphere, while upper atmo sphere is usually reserved for thethermosphere and exosphere. This usage is not universal, however,and one occasionally sees the term upper atmosphere used todescribe everything above the troposphere (for example, in NASAsUpper Atmosphere Research Satellite, UARS.)Subject: 1.2) How is the composition of air described? (Or, what is a mixing ratio?)The density of the air in the atmosphere depends upon altitude, andin a complicated way because the temperature also varies withaltitude. It is therefore awkward to report concentrations ofatmospheric species in units like g/cc or molecules/cc. Instead,it is convenient to report the mole fraction, the relativenumber of molecules of a given type in an air sample. Atmosphericscientists usually call a mole fraction a mixing ratio. Typicalunits for mixing ratios are parts-per-million, billion, ortrillion by volume, designated as ppmv, ppbv, and pptvrespectively. (The expression by volume reflects Avogadros Law for an ideal gas mixture, equal v olumes contain equal numbers of molecules and serves to distinguish mixing ratios from mass fractions which are given as parts-per-million by weight.) Thuswhen someone says the mixing ratio of hydrogen chloride at 3 kmis 0.1 ppbv, he means that 1 out of every 10 billion molecules inan air sample collected at that altitude will be an HCl molecule. Subject: 1.3) How does the composition of the atmosphere change withaltitude? (Or, how can CFCs get up to the stratosphere when they are heavier than air?) In the earths troposphere and stratosphere, most _stable_ chemicalspecies are well-mixed their mixing ratios are independent ofaltitude. If a species mixing ratio changes with altitude, somekind of physical or chemical transformation is taking place. That last statement may seem surprising one might expect the heavier molecules to dominate at lower altitudes. The mixing ratio of Krypton (mass 84), then, would decrease with altitude, while that of Helium (mass 4) would increase. In reality, however, molecules do not segregate by weight in the troposphere or stratosphere. The relative proportions of Helium, Nitrogen, and Krypton are unchanged up to about 100 km. Why is this? Vertical transport in the troposphere takes place byconvection and turbulent mixing. In the stratosphere and in themesosphere, it takes place by eddy diffusi on the gradual mechanical mixing of gas by motions on small scales. These mechanisms do not distinguish molecular masses. Only at much higher altitudes do mean free paths become so large that _molecular_ diffusion dominates and gravity is able to separate the different species, bringing hydrogen and helium atoms to the top. The lower and middle atmosphere are thussaid to be well mixed. Experimental measurements of the fluorocarbon CF4 demonstrate thishomogeneous mixing. CF4 has an extremely long lifetime in thestratosphere probably many thousands of years. The mixing ratioof CF4 in the stratosphere was found to be 0.056-0.060 ppbv from 10-50 km, with no overall trend. An important trace gas that is *not* well-mixed is water vapor. Thelower troposphere contains a great deal of water as much as 30,000ppmv in humid tropical latitudes. High in the troposphere, however,the water condenses and falls to the earth as rain or snow, so thatthe stratosphere is extremely dry, typical mixing ratios being about5 ppmv. Indeed, the transport of water vapor from troposphere to stratosphere is even less efficient than this would suggest, since much of the small amount of water in the stratosphere is actuallyproduced _in situ_ by the oxidation of stratospheric methane. Sometimes that part of the atmosphere in which the chemicalcomposition of stable species does not change with al titude iscalled the homosphere. The homosphere includes the troposphere,stratosphere, and mesosphere. The upper regions of the atmosphere the thermosphere and the exosphere are then referred to as the heterosphere. Subject: 2. THE OZONE LAYER Subject: 2.1) How is ozone created?Ozone is formed naturally in the upper stratosphere by shortwavelength ultraviolet radiation. Wavelengths less than ~240nanometers are absorbed by oxygen molecules (O2), which dissociate togive O atoms. The O atoms combine with other oxygen molecules to make ozone: O2 + hv -* O + O (wavelength * 240 nm)O + O2 -* O3Subject: 2.2) How much ozone is in the layer, and what is aDobson Unit ?A Dobson Unit (DU) is a convenient scale for measuring the totalamount of ozone occupying a column overhead. If the ozone layerover the US were compressed to 0 degrees Celsius and 1 atmospherepressure, it would be about 3 mm thick. So, 0.01 mm thickness at 0 C and 1 at is defined to be 1 DU; this makes the average thicknessof the ozone layer over the US come out to be about 300 DU. In absolute terms, 1 DU is about 2.7 x 10^16 molecules/cm^2. The unit is named after G.M.B. Dobson, who carried out pioneering studies of atmospheric ozone between ~1920-1960. Dobson designedthe standard instrument used to measure ozone from the ground. TheDobson spectrophotometer measures the intensity solar UV radiation atfour wavelengths, two of which are absorbed by ozone and two ofwhich are not . These instruments are still in usein many places, although they are gradually being replaced by the more elaborate Brewer spectrophotometers. Today ozone is measured in many ways, from aircraft, balloons, satellites, and space shuttle missions,but the worldwide Dobson network is the only source of long-term data. A station at Arosa in Switzerland has been measuring ozone since the1920s (see http://www The Salem Community by Miller Essay _Aside_: One sometimes hears that the US government killed the SSTproject in 1971 because of concerns raised by H. S. Johnstons work on NOx. This is not true. The US House of Representatives had alreadyvoted to cut off Federal funding for the SST when Johnston beganhis calculations. The House debate had centered around economics and the effects of noise, especially sonic booms, although there were some vague concerns about pollution and one physicist had testifiedabout the possible effects of water vapor on ozone. About 6 weeks after both houses had voted to cancel the SST, its supporters succeeded in reviving the project in the House. In the meantime, Johnston had sent a preliminary report to several professional colleagues and submitted a paper to _Science_. A preprint of Johnstons report leaked to a small California newspaper which published a highly sensationalized account. The story hit the press a few days before the Senate voted, 58-37, not to revive the SST. (The previous Senate vote had been 51-46 to cancel the project. The reason for the larger majority in the second vote was probably the statement by Boeings chairman that at least $500 million more would be needed to revive the program.).. Subject: 2.15) What is being done about ozone depletion?The 1987 Montreal Protocol (full text available on the world-wide web athttp://www.unep.org/unep/secretar/ozone/treaties.htm) specified thatCFC emissions should be reduced by 50% by the year 2000 (they had been _increasing_ by 3% per year.) This agreement was amended inLondon in 1990, to state that production of CFCs, CCl4, and halons should cease entirely by the year 2000. Restrictions were also appliedapplied to other Cl sources such as methylchloroform. (The details ofthe protocols are complicated, involving different schedules for differentcompounds, delays for developing nations, etc.) The phase-out schedulewas accelerated by four years by the 1992 Copenhagen agreements. A great deal of effort has been devoted to recovering and recycling CFCs that arecurrently being used in closed-cycle systems. For more information about legal and policy issues, see the books by and , and the following web sites:http://www.unep.org/unep/se cretar/ozone/home.htm http://www.unep.ch/ozone/ (European mirror site for above)http://www.epa.gov/docs/ozone/index.htmlhttp://www.ciesin.org/TG/OZ/ozpolic.htmlRecent NOAA measurements show that the _rate of increase_ of halocarbon concentrations in the atmosphere has decreased markedly since 1987. It appears that theProtocols are being observed. Under these conditions total stratospheric chlorine is predicted to peak at 3.8 ppbv in the year 1998, 0.2 ppbv above 1994 levels, and to slowly decline thereafter. Extrapolation of current trends suggests that the maximum ozone losses will be :Northern Mid-latitudes in winter/Spring: 12-13% below late 1960s levels, ~2.5% below current levels. Northern mid-latitudes in summer/fall: 6-7% below late 1960s levels,~1.5% below current levels. Southern mid-latitudes, year-round: ~ 11% below late 1960s levels,~2.5% below current levels. Very little depletion has been seen in the tropics and little isexpected there. After the year 2000, the ozone layer will slowly recover over a period of 50 years or so. The antarctic ozone hole is expected to last until about 2045. Some scientists are investigating ways to replenish stratosphericozone, either by removing CFCs from the troposphere or by tying upthe chlorine in inactive compounds. This is discussed in Part III.

It frequentlyrefers back to Part I, where the basic properties of the ozonelayer are described; the reader should look over that file first. The overall approach I take is conservative. I concentrate on whatis known and on most probable, rather than worst-case, scenarios. For example, I have relatively little to say about theeffects of UV radiation on plants this does not mean that theeffects are small, it means that they are as yet not wellquantified (and moreover, I am not well qualified to interpret theliterature.) Policy decisions must take into account not only themost probable scenario, but also a range of less probable ones. will probably do, but also the worst that he could possibly do. There have been surprises, mostly unpleasant, in this field in thepast, and there are sure to be more in the future. In general,_much_ less is known about biological effects of UV-B than aboutthe physics and chemistry of the ozone layer.
