Prevention and Mitigation analysis Essay

Early Sunday morning, precisely January 18,year 2004, two inmates namely Ricky K wassenaar; who was serving a prison sentence of 26years and his co-inmate Steven j. coy on a long time imprisonment of life sentence both decided to escape the territory of morey unit of the prison structure, a complex situated near Arizona at an estimated distance of 50miles( approximately 80,467metres) south west of phoenix . This morey is designed for an estimated capacity of 800 inmates as against the 840 inmates it housed. At morey, the number of inmate serving life sentence and protective segregation population is the largest in the correction history of Arizona. Probably, owing to the number of inmates housed in the morey’s territory (840 inmates) which was exceeding its design capacity and ultimately because of the limited number of correctional officers placed in security of the unit, these two inmates, Ricky K. Wassenaar and Steven J . Coy, came down heavily on the correctional officers, impounded the units tower and at long last conquered the officers . This historic incident represents the longest hostage incidence in the history of the nation. As early as 2. 30am in the cool of the day, the inmates who reportedly were numbered around 19 ,working in the kitchen were released from their place of abode such that each of them could report and perform his/her functions at the money kitchen. A short while later , an approximated time of 3. 15am, correctional officers Kenneth martin and the other female civilian kitchen employee came around into the kitchen such that they could oversee and ensure that each inmate does his/her duty as expected. At this instant in time, inmate Ricky k. wassenaar and Steven J. Coy have already drawn out plans to escape the prison territory and were just about to perfect the plans . Ricky k. Wassenaar entered the office of the kitchen through an open door, he was immediately followed by his co-inmate Steven J. Coy who stood by the kitchen doorway thereby preventing entrance and exit through the only opening. Both inmates had in their possession sophisticated weapons like â€Å"shank† which serve as a major recourse for attack when the need arose. With the weapon being powerfully handled by both inmate, inmate Ricky K. assenaar attacked one of the correctional officers, martins, he was frightened to put off his uniform, an official dress to which was attached his identification card which served as an insignia of martin’s membership of correctional department of the morey’s unit . Wassenaar further ordered martins to undress his boot, an instruction which martins quickly responded to. In the same vein, the other inmate Coy also in possession of shank, the knife like weapon, became confident and consequent upon which he dragged the female correctional officer down to the room where the tools were situated . This bloody inmate having frightened the female officer with his weapon ordered her to lie down with her stomach touching the floor. He then tied her hands together with her feet using electrical cables. Having impounded martin and the female kitchen worker, both inmates made a stroll for a short period. On their arrival at the morey unit, inmate Ricky K. Wassenaar seized martins uniform and thereafter wore it on himself and in reinforcement of his escape strategies,he also shaved off his beards. He did all these so that he could disguise through every check point as a correctional officer. With wassenaar now overwhelmed with full confidence of his perfected strategies, he buzzed at martins, inquiring for the kitchen telephone number and this ill-treated correctional officer martin complied with an unusual alacrity. At exactly 4:20am of that same Sunday morning, inmate Wassenaar desperately drew close an area where red yard gate was situated, an enclosure that surrounded a foot tower of an estimated height of approximately 20 feet. At the top of this tower were two correctional officers who by name were Jason N.  Auch and Jane Auch who having looked through the screen in confirmation of the person approaching were deceived by the disguising uniform wore by inmate Ricky K. wassenaar, and consequent upon the aforementioned, they buzzed the door open. Wassenaar came as one would have expected, struck down the two correctional officers and start communicating with coy, his accomplice. The rattling of keys alerted from the kitchen alerted Kelly and Debaughed. Coy was later incapacitated by one of the officers but wassenaar later came to rescue him and led him to the tower where Coy sexually assaulted an officer by . Wassenaar started shooting sporadically at the gate to scare away other correctional officers. 4 people namely Jones debauch,sergent Andrew and Kelly Went to the outer door to lock it and ran to the dining facility while the other officers withdrew to the administration building The head count of the inmates inside the dry area was also done The tactical supporting unit then came to rescue by removing all the inmates an well as the officers from the dining facility. They later found out that 2 officers were missing. one dabbled to the deputy warden conference room to take note of the staff on ground. Later at around 7:45 am ,the likes of DPS SWAT team,TSU snipers, as well as the DPS hostage negotiators surrounded the building The support for the incidence came from no less than 16 law enforcement agents with DPS giving up to 230 officers. A total of about 75 detective agents as well as experts in the areas of surveillance were on ground The FBI sent almost 100 personnel,100 field personnel was also provided by the Maricopa county sheriff’s division The FBI officers were instructed to adopt the force oriented policies. One of the reasons that could have led the incident of the Arizona prison break was the fact that Doc officers were not well remunerated when compared to others in the same compartment This has led to economic hardship with subsequent reduction in the quality of life of the workers as well as their family Some of the sergeants openly confess their inability to afford the basic daily needs because of the meager salary saying also that most officers were less paid even than the officers that guard and supervise. It is therefore recommended that there must be a review of the salary scale and a balance should be achieved in the payment scale of the municipal, federal and county correctional officers and that of the surrounding Arizona states. Another problem that could have led to the incidence is the fact that the lowering of the Qualification standards to fill the available vacancies at the Arizona. It is therefore recommended that nothing but excellence should henceforth be promoted and upward review of the worker’s salary should be undertaken and sustained. It should also be noted that as at the time of the incidence that morey unit suffered from negligence and lack of appropriate expectation of elements of professionalism there were so many administrative blunders in the preceding years of the incidence among the staff even though the action of some of the staff members in rising to the incidence is highly commendable. The panel seeing to the events that led to the incidence noted that a lot of administrative negligence and improper supervision and action led to the incidence. It is therefore recommended that the DOC administrative director should determine if changing or substituting some staff assignments or disciplining some of the erring staff would be contributory. The pervasive nature of the incidence should be ascertained and subsequently to isolate and carry out procedures that could remedy the problem to avert future reoccurrence. It was also noticed that DOC has stopped conducting operational account audit of the facilities of the prison since 2000 and it is recommended that such practice should be revisited to ensure that proper and effective administration and management of prison facilities. There is also need for effective communication skills among the staff in order to foster prison security and operational success. Policies that favor indirect and not direct observation of the inmate and those that promote bad and ineffective communication between offenders and prison officers should be jettisoned The building and operational modus operandi should be that which support security and effective management sytem. The hostage taking event that occurred at the Morey unit of the was regrettable in history and it was catastrophic with attendant injury and irreparable loss to correctional officers and facility employees It is an eye-opener to the various challenges and jeopardy that corrections experts are battling with everyday. It is therefore important to properly and adequately fund and pay attention to the corrections operations. Good organizational quality cannot also be overemphasized encouragement and optimum investment in people involved in manning this highly sensitive sector of national security is therefore of utmost importance. Such set of individuals who have one way or the other dedicated themselves to this course should be well remunerated and properly trained and educated with nothing but very high intelligence quotient. They should be regarded as special people and treated as such. They must be compensated. I believe with these steps, future reoccurrences could be adequately averted.

The Theme of Music in Captain Corelli’s Mandolin

‘She realised suddenly that there was something about music that had never been revealed to her before: it was not merely the production of sweet sound; it was, to those who understood it, an emotional and intellectual odyssey.' The theme of music takes on many forms and is central to understanding many characters and situations in the novel. The title of the novel itself mentions the all-important Mandolin, which emphasizes its importance beyond anything else. When we are first introduced to Captain Corelli's mandolin, it is instantly evident that he has given it a woman's name, Antonia, personifying the object. He also refers to the playing of the instrument as if it is crying in his arms as he plays it. As the main focus in this book is eventually the relationship between Pelagia and Corelli, music appears to play an important role in this relationship. Pelagia cannot work out why it is that a talented musician would settle for a life in the army, and it is this mystique and talent that attracts her to the Captain. There are evident fronts that both Pelagia and Corelli both put on, Pelagia as the innocent and stern Greek who's duty it is to hate the Italians, and Corelli as the Italian soldier getting drunk with prostitutes. But it seems that when Corelli begins to play his mandolin, both these fronts disappear to be replaced by Pelagia's genuine admiration and Corelli's genuine love for the instrument. The link between the mandolin and the relationship is made clear by Corelli's comparison of the instrument to Pelagia as well as the sound it makes: ‘How like Pelagia is a mandolin, how gracious and how lovely' ‘I think of Pelagia in terms of chords' Not only does the mandolin and its sounds reflect the attraction of the couple, but it also sums up quite perfectly the situation that prevents them from being lovers, as Corelli mentions in chapter 42. ‘Pelagia is sad and I pick up Antonia and play re minor. She looks up and says â€Å"That's exactly how I was feeling, how did you know?† and I would have liked to have said, â€Å"Pelagia I love you, and that is how I know†Ã¢â‚¬Ëœ The theme of song appears throughout the novel, many characters display a need and a use for music and this becomes evident when considering this theme. The uses for music in the novel are varied and it is interesting to compare each use of music in different situations to gain insight into its value. Lemoni, the innocent and pure child that everyone in the villiage has time for uses song to keep her amused, and to create a relationship with the wild animals she loves so much. It is mentioned that insanity is only acceptable when one is a child, and Lemoni's attempts to teach a stray dog to sing in chapter 9. ‘†He's singing! He's singing!† Cried Lemoni and joined in â€Å"A-ee-ra, a-ee-ra, a-eera† She also plays with the crickets and gets herself bitten by one. It is not mentioned but perhaps Lemoni is drawn to the loud song of the cricket and may have attempted to sing along with them too. Her purity and wild, uncorrupted interpretation of the songs of the animals seem to bring her closer to them. We never see Lemoni playing with the other children in the villiage, perhaps there are none but it would appear more likely that she seeks her companionship in the singing animals she spends all her time with. Another example in the novel where song is used for an alternative reason is when the brigands are found by Carlo and Francesco, drunk and singing in the tower that they have seized by force. One would assume that any outlaws would be lying low, or on heavy guard for attackers, but it seems this half-hearted war against people not really considered to be the enemy has brought out the side of the soldiers that would prefer to be drunk and mid-song than armed and waiting for combat. This element makes it that little bit harder for Carlo and Francesco to kill these men not so different from themselves, but in times of war these feelings are expected to be brushed aside by soldiers. ‘There was the sound of singing from the tower, and it seemed they must have been a little drunk' But it is not just the situation of war that brings about song in the characters in the novel, it seems that any chance of celebration, whether it be a small victory, the ringing of the church bells, a tradition or the arrival of an expected miracle requires musical accompaniment of some sort. ‘Finally arrived at the point where singing was both natural and inevitable, they sang together a cantada' So from Corelli's gentlemen's singing club, to Lemoni's singing animals, and the composition of Pelagia's march, it is not difficult to identify the importance of music, song and sound in Captain Corelli's Mandolin.

Allergies and other type of immune hypersensitivities

Allergies and other type of immune hypersensitivities are important undesirable side effect of our immune system. These problems occur in people who have a specific allergic tendency. Anyone suffering from allergy can take comfort that there are over 50 million fellow American sufferers of this problem. Roughly one in 6 American is afflicted with allergic problem. Fortunately, in very few people allergic condition can become life threatening.In most allergy sufferers problems due to allergy appear to be trivial such as runny nose, sneezing, itchy eyes, sinus problem, rash and skin complaints but these otherwise minor problems can make the allergy sufferers lives quite miserable. Our immune system, essential for defending our bodies against foreign organisms, produces antibodies and activated white cells to attack invaders like viruses and bacteria. Occasionally, the immune response results in an inappropriate or exaggerated reaction called hypersensitivity. Hypersensitivity is classi fied into four types; Types I, II, III and IV.Types I to Type III hypersensitivities are antibody-mediated while Type IV is a cell mediated hypersensitivity. Type II & III are Immunoglobulin G (IgG) mediated while Type I sensitivity is Immunoglobulin E mediated. The term ‘Allergy’ is confined to IgE mediated reactions or Type I hypersensitivity [Levinson, 2004] . Immunoglobulin E (IgE) is our body’s host defense system against certain parasites such as worms. In developed countries, where parasitic infection is uncommon, most people have no or very low level of IgE.An allergic reaction or allergy occurs when our body’s immune system mistakenly considers a harmless substance, called ‘allergen’ as dangerous and starts producing IgE to trigger an allergic reaction [Levinson, 2004]. Types of Allergies Allergic Rhinitis: This type of allergy causes swelling of nasal mucosa with respiratory discomforts like sneezing and runny nose by inhaling allerg ens such as pollen, molds, dust, dander and other allergens. Allergic Conjunctivitis: The allergic reaction affects the eyes, redness and itching are the signs of this allergy. Bronchoconstriction:Wheezing and shortness of breath caused by narrowing of bronchial cavities. Asthma is a serious type of bronchoconstriction. This type of allergy is also caused dust, pollen, mites, and other allergens. Ear Allergies: The allergens affect ear passages causing pain and impairing hearing. Skin Allergies: Itchy rashes, blisters, hives, and contact dermatitis caused by touching certain substances such a poison ivy or food items are manifestation of this type of allergy. In allergies where swelling occurs as a result of hives, swelling can cause breathing and swallowing difficulties. Food Allergies:Certain kind of foods, such as fish egg, nuts and milk can cause intestinal upsets due to allergic reactions. Time Delayed Allergies: An allergic response appearing hours or days after application or absorption of an allergen; including contact dermatitis and bacterial allergy [Allergies, 2006] Anaphylaxis: This is the most severe systemic allergic reaction causing bronchoconstriction, swelling of body tissues, vomiting, cramps, skin reactions and drop in blood pressure, coma and even death [Guyton & Hall, 2006]. Allergy can also be classified on the basis of its effect and allergen as:? Respiratory Allergies ? Skin Allergies ? Food Allergies ? Asthma ? Drug Allergies ? Sting Allergies Causes & Risk Factors Problems with normal immune responses are believed to be the result of both genetic and environmental factors. Children of allergic parents are more likely to have similar allergies though the allergens may differ. [Allergies, 2006] Genetic research is leading scientists to believe that skin and tissue specific genes may be responsible for causing allergy symptoms [NIH, 2000]. Stress and anxiety are acknowledged a common cause of allergic reaction.[Lenzoff, 1997] subjected p atients suspected of multiple chemical sensitivities concluded that in some sufferers allergy symptoms might be triggered by their perception of an environmental insult. Increasing use of chemicals has resulted in introduction of new toxins into the atmosphere. The increase in number of allergy cases during the last decades is often attributed to atmospheric pollution [Bornehag et al, 2004]. Better identification of problem as allergy and not other minor condition such as cold is perhaps also responsible for increased numbers. Allergy or ColdA number of symptoms of common cold are also the symptoms of allergy. It is not unusual to mistake one for the other. The major difference between the cold and flu are [Allergy, 2006b]: – Both cold and allergy show the common symptoms of allergy but the cold is also accompanied by fever and pain. – Allergy begins immediately after exposure to the allergen while cold takes a day or more to develop to full strength. – Cold is a self terminating diseases and the symptoms disappear in 3 to 7 days while allergies continue till the person remains exposed to the allergen AllergensThe body’s immune system has the capability to attack a foreign organism. If it identifies a substance such as pollen as foreign, even mistakenly, the defense mechanism comes into action and IgE is produced to fight off that particular substance. Thus, there will be separate IgE for pollen and for dust allergies. There are many allergens as any person could be allergic to a common substance, which is not an allergen to others, but the common allergens include pollen and fungus from weeds, grasses. Trees and outdoor mold, dog and cat dander, dust particles, noxious vapors and smog, foods such as fish, eggs, nuts and insect bites.Signs & Symptoms In addition to the usual sneezing, runny nose, rashes allergy and red or itchy eyes symptoms include atopic dermatitis, contact dermatitis, headache, earache, hives, coughing, sinusitis , and other discussed above. Medical Tests & Diagnosis Methods/Tools The diagnostic tests for Allergy include: †¢ Skin Prick Test (SPT) †¢ Total IgE Test †¢ Range of Specific IgE Test †¢ Phadiatop Assay †¢ Specific IgE Pediatric Food Mix fx5 Skin Prick Test: Skin prick test is a common and simple method of diagnosing allergy.In this test small amount of suspected allergens are injected either intra-dermally or into the scratching made in the patient’s skin. Patient allergic to any of the allergen shows a visible inflammation after half an hour. Skin Prick Test (SPT) only responds to allergens used in the test. In cases where patient is allergic to any other allergen, this test will not show. Some patients with delayed type hypersensitivity may be adversely affected by the test. Total IgE Test: Patient serum IgE test is another method used for determining Type I hypersensitivity.The test provides useful indication for allergy. This test however is not considered conclusive. The test measures total IgE value and is said to be only to report existence of allergy 60% of the time [Labspec, 2006]. The extent of symptoms and type of allergy has an effect on the result. Severe skin allergy shows a higher IgE value than rhinitis or conjunctivitis. [Labspec, 2006] also point out that Standard IgE values appear to vary with ethnicity of the patient. Range of Specific IgE Test: Some diagnostic suppliers are manufacturing specific IgE test for allergens.Specific tests for over 400 allergens are available. Some of these specific tests have been approved for routine tests, other are awaiting approval. [Labspec, 2006] Phadiatop Assay: Instead of testing total IgE or specific test for a single allergen, this test tests serum for a wide range of inhalant allergens. The test is said to be 95% reliable and can be used to exclude allergens included in Phadiatop assay. Specific IgE Pediatric Food Mix fx5 His test is similar to Phadiatop Assay, but in stead of inhalant allergens, ingestant allergens are tested.This test is still in approval stages for general laboratory use. Treatment Options Many people with mild allergies avoid seeking medical help, but it is important to know that allergies if left untreated can develop into serious health problems like infections in sinuses, throat and ears, chronic respiratory problems, skin problems such as eczema. The treatment Options for allergies include: †¢ Avoid allergen environment and/or food †¢ Over the counter medication (histamines) †¢ Prescription drugs & nasal drops, †¢ Allergy shots †¢ Allergy Drops †¢ Immunotherapy †¢ Alternate TherapiesOnce a person knows the substance that causes allergy, the best treatment is to avoid that substance. However avoiding allergen is not always possible as it is not possible to breathe. Food allergens can be easily avoided [When Should I Get Medical Treatment for Allergy, 2006] . In a very large number of case s of mild allergy over the counter medication is all one needs to relieve the symptoms. It is important to consult a doctor for over the counter medicine too, as some of these medicines if used excessively can cause serious side effects. Most of the histamines cause drowsiness.Antihistamines and decongestants relieve the symptoms of most allergy sufferers. Again, a physician’s advice should be sought. Many new antihistamines relieve the symptoms of allergy without causing drowsiness. In sinus congestion, nasal sprays available on prescription provide quick relief from symptoms of allergy. Allergy shots prevent the allergen from being recognized as a foreign body. This treatment is becoming very popular. Sublingual drops also known as sublingual Immunotherapy (SLIT) is an alternate to allergy shots and has the same principle of desensitization.Oral application of SLIT is also considered convenient by the patients. Those interested in alternative medicine often recommend severa l alternate therapies. Dietary supplements are said to increase health of immune system and prevent allergies. The other alternative medicines are beyond the scope of this paper. [Allergies, 2006a] provides several references to alternative treatment websites. Anaphylaxis must be considered a medical emergency and immediate medical help must be sought as it can cause low blood pressure, hyper-constriction, coma and even death.Prevention Methods The best prevention is to avoid the allergen responsible for causing the allergy. Cross the counter medicine approved by a patients physician may also be used before coming into contact with allergens. In view of the number of sufferers, various equipments such as vacuum cleaners, humidifiers, beddings and air purifiers are available in the market to control domestic allergens. A physician may be able to advice about prevention methods about other specific allergies.

Discussion Forum Post - Assignment Example Human nature and the tendency to change can be viewed from two dimensions, which include norms and lifestyle. Human nature is not independent of other influences because, in the absence of external factors, human nature can be said to be fixed. Cultural issues, norms and way of life determine to a great extent human behavior, attitude and the nature of interactions. A number of issues arise in so far as the study of the nodes is concerned. Study of the nudes, especially as depicted in the artwork symbolizes the human beauty and the inherent qualities posed by either gender (Powers 80). Consequently, nudity demonstrates various aspects of human life, such as energy and emotions manifested by the posture and the interventions depicted by the nudes (Powers 89). Nudity simply brings out the inner human into display and provides a broad basis over which a number of issues can be

Terrorism on the Internet Essay Example | Topics and Well Written Essays - 3000 words

Terrorism on the Internet - Essay Example The attack on the World Trade Center was one where terrorists wreaked an unprecedented level of destruction and the attention of the world was drawn sharply to the dangers posed by the terrorist threat. Sterne (2003) defines terrorism as â€Å"as an act or threat of violence against noncombatants with the objective of exacting revenge, intimidating, or otherwise influencing an audience.† Over the years, the face of terrorism has changed – it is no longer restricted to state sponsored terrorism, but has evolved into specialized local cells, with individual terrorist elements spreading threat in order to achieve their own selfish political or other ends. Sterne clarifies that in this context, terrorism is not the kind of enemy that can be combated on an all out open combat basis. She defines terrorism as â€Å"a kind of virus, which spreads as a result of risk factors at various levels: global, interstate, national and personal."[www.buzzflash.com]. With increasing globalization, the use of the Internet has widened to encompass a new sphere of activities that are facilitated through the electronic medium{Kusher 1998). It is now possible to achieve on an individual basis, a scope of activity that would have previously necessitated the availability of a vast amount of resources and several people. But through the cheap electronic medium, it has become possible for computer savvy individuals to engage in several criminal and terrorist activities that are characterized by the compromising of sensitive information and by large scale destruction. Since most commercial and Government activity has now become e-based, terrorists can cause a great deal of damage by hacking into the databases of Government organizations.

Social and Environmental Impact of Diamond Mining in Africa Case Study

Social and Environmental Impact of Diamond Mining in Africa - Case Study Example The paper tells that there were some De Beers who had done some research in this region and had identified it as a potential mining ground for diamond, although they did not reveal the discovery to the locals The process that begun as a simple business soon attracted the attention of international investors and by the time the government tried to intervene, the process had gone far; many people had already gotten established the business. The government had to exert excessive force to disrupt the illegal activity and many people were killed in the process â€Å"hospital officials at Mutare General Hospital reported on one occasion, the arrival of 75 bodies believed to have been killed in the ‘Chiadzwa conflict’ †. Since the discovery of diamond, the community has experienced some social transformation, which is quite different from other regions that also carry out diamond mining. The major difference being that most of the other diamond mining areas in Africa hav e been affected by rebel groups, though this was during the initial stages. The illegal mining by the locals later transformed into the participation of local police also as illegal miners. It called for the intervention of African Consolidated Resources to initiate a programme to oversee the fencing of the mining region, but the program was ignored once the practice was declared free to all. The government had to again use the military operation to stop all the mining activities that had been regarded as illegal. During this process, locals suffered much oppression from the military, especially when an operation that was called Wakazvionepi which meant â€Å"where did you get your riches from† was launched. It also took the intervention of civil rights activists to condemn the allegation regarding the human rights abuse. The new panners dominated their daily functions in Chiadzwa and the neighboring regions; as a result, the local communities were gradually getting displaced .

African American History Essay Example | Topics and Well Written Essays - 1250 words - 1

African American History - Essay Example The following study text will evaluate King’s role in the Civil Rights Movement with regards to his unique and effective strategies applied in acquiring overwhelming victory against white supremacy. Born in January 1929 as Michael Luther King, King grew up in religious environment and both his father and grandfather were pastors at the Ebenezer Baptist Church in Atlanta. In 1948, he earned a B.A. at the Morehouse College and proceeded to the Crozer Theological Seminary in 1951. In 1955, he earned a doctorate from the Boston University where he also happened to meet his wife Coretta Scott. After his graduation from Boston University, he began his pastoral role as at the Montgomery Avenue Baptist Church. This is where his journey into world history began. Rosa Sparks, a young black woman refused to give up her seat for a white person to sit in a bus and this had sparked controversy all over the United States around 1955. By chance, King’s Montgomery Church was chosen as the meeting venue to host one of the meetings to discuss the matter, and King happened to be there1. The meeting acted to recruit King into his call of advocating for the end to racial discrimination in the United States. Rosa Sparks was thrown into jail and King could not stomach the sense that she had been jailed for failing to give her seat to a white person. Following this, he planned his first public demonstration. In the same year, he mobilized the entire Montgomery [mainly African American] community to boycott the city’s transport service. He demanded equal rights for all. After an unending one year of boycott, a court ruling in Browder V. Gayle put an end to the discrimination on the public bus service and everyone was free to board the buses. This did not end, but sparked a new struggle aimed at eradicating racism all over the United States2. Martin Luther King Jr. was

Numbering Technique Essay Example | Topics and Well Written Essays - 1250 words

Numbering Technique - Essay Example The author portrays science as a source of fascination, in this essay. In addition, he also believes that science possesses potential powers in liberating people's minds where its method and rationality can be applied to reality. In Brecht's opinion, nature is a resource for scientific and technological experiments to be exploited for the benefit of the whole human society, rather than being a tool to promote the interests of certain social classes that control the resources of science. This idealism reflects an affinity to Marxism, and it is clear that Brecht's political view becomes apparent in his usage of words such as 'bourgeoisie' and 'proletariat'. The numbering technique, or, in other words, the form used by Brecht, serves as a device to further support his central idea-his goal in letting the audience to be able to 'alienate' from acting (Are you using the words in the context of pretending If so, please replace 'acting' with 'pretending') and encouraging them to change their habits and assumptions about the society. The way the author numbers each paragraphs, to separate one from the other, allows readers brief pauses to ponder over the content. Instead of being influenced by the author, the readers receive the opportunity to think and remain detached of the author's arguments. In comparison, Brechian theater's estrangement effect appeals to reasoning, as it uses various methods to produce a critical attitude in audience. This concept departs from the traditional "empathy" that prevents audience from thinking freely, in order for them to see the real message that lies hidden in the play that may be socially unquestioned. It appears that such an intention of trying to force the audience to 'think' is Brecht's answer to transform the society through the changes made in theatre. There are several points in which the characteristics of alienation effect align with the changes in theatre, and as a consequence, achieve Brecht's goal of changing the audience of the scientific age. One characteristic is that Brecht wants his play to be separated into parts rather than be a continual piece. Brecht suggests: "As we cannot invite the audience to fling itself into the story as if it were a river and let itself be carried vaguely hither and thither, the individual episodes have to be knotted together in such a way that the knots are easily noticed. The episodes must not succeed one another indistinguishably but must give us a chance to interpose our judgment." (201) This may be done through having the orchestra play on stage rather than off-stage, or having a narrator to talk to the audience through out the play, or adding social point in between titles, etc. These techniques create the same alienation effect, similar Brecht's use of numbers to separate his ideas in "A Short Organum for the Theatre."

Deciding Right from Wrong - Essay Example However, even after thousands of years, we are still unable to make universal principles with respect to rights and wrongs. The rights of some people are the wrongs of the other people. For example, keeping more than one wife is a sin or a wrong thing for Christians whereas Muslims find nothing wrong in it. Based on individual perceptions, many scholars and philosophers tried to segregate between the rights and wrongs with the help of some ethical theories. This paper briefly analyses the rights and wrongs with the help of some ethical theories formulated by some eminent scholars and philosophers. â€Å"The concepts of ethics fall into two main categories; notions having to do with morality, virtue, rationality, and other ideals or standards of conduct and motivation; notions pertaining to human good or well-being and the "good life" generally† (Slote, n.d, p.2). Killing of enemies in a war is perceived as a right thing even though killing of innocent people are perceived as a wrong thing. Moreover, capital punishment is accepted as a morally right thing by many countries whereas some other countries reject capital punishment, purely on moral grounds. In other words, some people believe that killing of an antisocial element is good for the rest of the people in the society and hence such killing should be made legal, considering the future wellbeing of the other people. Most of the countries give capital punishments to terrorists because of the above notion. However, some people are of the view that taking the life of another person cannot be justified under any circumstances because of the immense value associated with human life. In their opinion, we are only creations and only the creator has the authority to make any modifications on our lives. Moreover, killing of criminals will deny them the opportunity to correct themselves. Some of the Muslims have the belief that killing of enemies of their religion is a sacred act. In short, killing of people i s justified under some circumstances by some people whereas others object it under any circumstances. In other words, moral theories associated with killing of other people are widely differing in different places. â€Å"The categorical imperative of Immanuel Kant, tells us that we may not use or mistreat other people as a means either to our own happiness or to that of other people† (Slote, n.d, p.2). Moreover, Kant argued that "Act only on that maxim through which you can at the same time will that it should become a universal law"(Categorical Imperative, n.d). Kant believed that the moral principles were applicable universally. In his opinion, it is impossible to have a moral principle right at some places and wrong at other places. Nobody knows from where we come and where we go after death. As per Kantian theory, human being has a special role in the creations and hence moral principles with respect to human cannot be applied to other living things. However Kant strongly criticized the segregation of good and evil based on the personal beliefs or the religious beliefs. In his opinion,"Act in such a way that you always treat humanity, whether in your own person or in the person of any other, never simply as a means, but always at the same time as an end†(Categorical Imperative, n. d.) â€Å"Utilitarian consequentialists regard pleasure or the satisfaction of desire as the sole, intrinsic human good, and pain or dissatisfaction as the sole,

Hospitality and Destiny in the Odyssey and Sundiata Essay Example for Free

Hospitality and Destiny in the Odyssey and Sundiata Essay Princetons Wordnet defines hospitality as [the act of] cordial reception: [or] kindness in welcoming guests or strangers. Since the start of this semester, we have read about two different journeys in which hospitality plays an important role in fulfilling the destiny of the main character. In Homers Odyssey, many examples of this are apparent, whether they are for the benefit or the downfall of the protagonist Odysseus. However, Odysseus is not the only one whom hospitality rules. His son Telemachus also is affected by his hospitality towards others. In Nianes Sundiata: An Epic of Old Mali, the theme of hospitality runs thick throughout the narrative, as Sundiata is greatly affected by how the other characters receive him. If it were not for the hospitable acts shown to both of the weary travelers, Odysseus and Sundiata may not have been able to return to their homeland. The extreme observance of hospitality in the two texts may be compared with the golden rule: treat others, as you would like to be treated. The rule of hospitality may also be applied to the gods. In the time of Odysseus, gods or deities could take the form of humans or alter human appearance. If a stranger showed up at your door, you might not know whether they are mortal or immortal. If you turned away a god or someone loved by the gods, this could anger them and in turn they could avenge your inhospitable act. The gods might respond with not giving you a good harvest or make your life a complete hell, as Poseidon did to the journey of Odysseus. Good hospitality was to be displayed towards everyone, no matter age or gender. In The Odyssey, not only was Odysseus treated well by the lords of the lands he visited, but, his young son, Telemachus, was treated with respect. In Sundiata, hospitality was not only showed towards men, but also women. When Sassouma forced Sogolon into exile, the neighboring lands and kings she and her children encountered treated them with generosity. In The Odyssey many hospitable acts were displayed before kings even knew who had ventured to their land. When Telemachus travels to Pylos seeking information about his father, King Nestor treated him and Pallas Athena with much respect. As they approached the citadel King Nestor and his son spotted them. As soon as they saw the strangers, all came crowding down, urging  them to sit. Nestors son Pisistratus, first to reach them, grasped their hands and sat them down at the feast on fleecy throws (Homer 108, lines 39-44). This demonstrates how welcoming the Pylians are towards strangers. This is truly a hospitable greeting because the Pylians were not just carousing around, but in fact were involved in a feast in honor of the god Poseidon. They invited these foreign guests in as if they were members of the royal family to take part in the feast. Menelaus, like Nestor, treated his guest as part of the royal family before knowing their names. Menelaus provided Telemachus and Pisistratus with food but not just any food but, He passed them a fat rich loin with his own hands, the choicest part, that hed been served himself (Homer 126, 74-75). The Greeks loved to eat and what an honor it would have been to be given the kings slab of meat. He also had women bathe them, rub them with oil, and provide them with warm fleece and shirts to wear. Before Telemachus was to leave, Menelaus insisted on giving him many gifts but Odysseus young son respectfully declined any such gifts. Menelaus insisted on giving him a mixing bowl forged to perfection made of solid silver with a lip of gold made by Hephaestus himself (Homer 144, 692-694). The hospitality shown by Menelaus is a great example of treating others as you would like to be treated. Menelaus, the great and lustrous king, showered his guest with the best of everything, as he would have wanted done for him. Not only in The Odyssey and ancient Greece was hospitality shown towards strangers, but it also occurred in Sundiata. The first stop on the exile journey of Sundiata was Djedeba. The king there received them with a little mistrust, but mentioned that everywhere the stranger enjoys the right to hospitality (Niane 29). The stay with the king of Djedeba lasted two months and not much is mentioned in the novel of what was given to Sundiata and his family. But the stay with Djedeba emphasizes the point that even though someone may be wary of allowing strangers to stay with them, the act of hospitality is entitled to all strangers who need a place to stay. Those who were members of the highest social class were not the only ones expected to practice hospitality. Hospitable acts were to be practiced by  and towards all social classes. When Odysseus returned to Ithaca, Athena disguised him by dressing him in beggar clothes. She directed him towards the swineherds establishment. The swineherd had to save the king from his beastly dogs and after this invited him into his home. The swineherd, Eumeaus, told Odysseus, Its wrong, my friend, to send any stranger packing-even one who arrives in worse shape than you (Homer 303, 64-65). Odysseus told him, May Zeus and the other gods give you your hearts desire for the royal welcome you have shown me here (Homer 303, 60-62). The hospitality that was shown towards the beloved king no doubt pleased the gods. Even though the swineherd could not provide the extravagant baths, bedding, and food of kings, he still gave Odysseus the best of what he had. Odysseus was invited by the swineherd to sit down on a pile of brush and twigs covered with the skin of a shaggy wild goat, which was the swineherds own good bedding. He fed the king scrawny pigs that were freshly slaughtered. This was the best food that could be offered by the swineherd because the suitors who overran the home of Odysseus took the fattened pigs. The hospitality shown by the swineherd proves that one does not have to offer the best of things to show hospitality towards strangers. Hospitable acts were not expected only to be shown towards the living, but the deceased deserved the same rights. In Sundiata, when it came time to leave Mema and return to Mali, Sogolon passed away. Sundiata said to the king, King, you gave me hospitality at your court when I was without shelter†¦In any case, allow me to bury my mother before I go (Niane 46). The king was outraged that Sundiata wanted to leave his country and at first refused. But either it was fear, or out of respect he had for Sundiata, or a combination of both, Sundiata got his wish. Burial grounds were provided for Sogolon in the country of Mema. Showing hospitality towards the dead is as important towards showing it towards the living. Hospitality was not to go unnoticed either; hospitable acts were expected to be repaid when the time arose. A great example of repaying hospitality came from Menelaus. Telemachus and Nestors son arrived outside the gates of  Menelaus estate and lord Eteoneus runs through the halls and delivers the news to the battle-hardened king and ask, Should we unhitch their team for them or send them to someone free to host them well(Homer 125, 33-34)? Menelaus responds hastily, Just think of the hospitality we enjoyed at the hands of other men before we made it home†¦And bring them in strangers, guest, to share our flowing feast(Homer 125, 38-39, 41-42). Menelaus wants to show the same hospitality to those who visit his land just as the rulers showed him when he was in need. Political alliances also proved to be good situations to practice hospitality. One of the stops on the exile journey of Sundiata and his family was the region of Ghana. When they arrived they were greeted by the kings brother who made them comfortable and brought water for them to quench their thirst. After Sogolon explained where they were from and why they were in exile the king, Soumamba, responded, No one has ever found our hospitality wanting. My court is your court and my palace is yours (Niane 34). The reason for easy welcoming of the strangers was the history of the relationship between Mali and Ghana. The king also said to his brother, Brother, look after our guests. Let Sogolon and her children be royally treated and from tomorrow let the princes of Mali sit among our children (Niane 34). Another hospitable act in Sundiata, which involved alliances between nations, happened again in Mema. This alliance had to do with the family relationship of two kings. Upon their arrival at Mema, the sister of the king greeted Sogolon and her family and housed them in a wing of the palace. They were recommended by Soumaba to come to Mema, and after showing the king of Mema, Moussa Tounkara, a letter from Soumamba the king said, My cousin Soumaba recommends you and that is enough. You are at home. Stay here as long as you wish (Niane 36). Sundiata became so beloved by the people and the king that he became viceroy and even secured a spot as heir to the throne of Mema. This is example of hospitality starts out as a friendly gesture, and evolves into a new set of hierarchal position for the traveling family. The hospitality shown by the people of Mema allowed the exiled royal family of Mali to become pretty much citizens of this new country. The act of hospitality is prevalent in both the Odyssey and Sundiata. Not  only do kings of regions and countries practice this act, but hospitality is expected to be practiced by everyone regardless of their social class. Hospitality should be shown towards everyone regardless how the two parties affiliate with one another. Hospitality goes along way in the stories of Odysseus and Sundiata. It creates relationships with lands that others fear, like the region of Ghana in Sundiata. It also creates relationships with those who have no prior relationships to those of foreign lands, like Telemachus creates with the comrades of his father. If only this type of hospitality was prevalent in society today our world would be a much more friendly and fearless place to live. Fagles, Robert. The Odyssey. New York: Penguin, 1996. Niane, D. T.

Male and Female Roles in Society Essay Example for Free

Male and Female Roles in Society Essay Mozart Beethoven Within the classical style of music stand two well-known, well-versed composers: Wolfgang Amadeus Mozart and Ludwig van Beethoven. Both men were crucial, influential figures in the Classical era of music and composed works that are still held with great praise and dignity over 200 years later. To passive listeners, Mozart and Beethoven are very similar in their style and compositions. Although similarities do exist, their music and personal lives differed, most appropriately due to the periods in which they became famous. Mozart, considered the best and most successful composer of the Classical era, began his work at a time when classical music was prominent. Beethoven, meanwhile, was successful during the transition between the Classical and Romantic eras. Although hes considered an influential figure of the Classical era, he is also credited with developing a new style and pushing the boundaries of classical music. Because Beethoven was born when Mozart began composing his early successful works he was able to take advantage of learning and studying classical music when it was at its best. Both composers were born into highly-musical families. Their fathers were their first teachers who considered their sons musical prodigies. Sonically, their works were quite different. Its often said that Beethoven stands out more than Mozart in classical music, that his compositions are more complex are more in touch with personality and emotion. At the same time, it could be said that Mozart was ahead of his time. Beethoven borrowed many ideas from numerous composers before him, including Mozart; in adding his own touch he made his works loved then and now

Short Research Proposal On Fear Of Crime

Short Research Proposal On Fear Of Crime In this short research proposal, I will critically analyse and justify the reasons why I have chosen to use in depth interviews compared to other qualitative methods in order to research fear of crime among young men aged between 18-25 in inner London. My primary objective is to find out to what extent do young men aged 18-25 living in inner London fear crime. Altogether there are three main types of qualitative data; they are in depth interviews, focus groups and ethnography (Bryman, 2004). However, before I justify the reasons why I have chosen to use in depth interviews compared to focus groups and ethnography I will first give a brief definition of fear of crime among young men. In order to carry out a short research proposal, it is important that I have background knowledge on my research topic. On the whole, there are many different types of interviews however in my research I will be conducting in depth interviews with thirty young males aged between 18-25. I have chosen in depth interviews to conduct my research as this will provide me with rich data, it will also enable the participants to express their feelings and experiences on fear of crime (Bryman, 2004). There are two different types of in depth interviews they are known as semi-structured and unstructured interviews. In my research, I will be carrying out semi-structured interviews whereby I will have a set of questions to ask the participants. In Semi structured interviews the questions are usually open ended hence this will enable me to gather rich, detailed information about the experiences and attitudes towards fear of crime among young men (Miller and Brewer, 2003). On the other hand, although unstructured interviews are a great way to build rapport with the respondent there is a slight possibility that the participants may go off on tangents, and hence this will be more time consuming (Seale, 2004). In relation to my research topic, by carrying out a semi-structured interviews young men will feel more comfortable to talk about their experiences. I will now discuss and justify the reasons why I have decided to select in depth interviews compared to focus groups and ethnography to carry out my research. According to May, in depth interview is a great way to understand the attitudes and feelings of an individual on a specific topic (May, 2001). In depth interviews will enable me to explore in more detail the fear of crime among young men in inner London (Seale, 2004). Hence, compared to focus groups and ethnography, in depth interviews will allow me to have a better understanding of the individuals views, experiences, opinions and feelings towards fear of crime among young men (Seale, 2004). Another advantage of in depth interviews is that it allows flexibility; interviews can be adjusted to cater the needs of different types of people (Sarantakos, 2005). Furthermore, another advantage is that researchers can ask questions on the spot, probe the participants as well as change the order of questions if needed (Miller and Brewer, 2003). Another advantage is that during my study, I will have full control of the environment, under which questions are answered (Sarantakos, 2005). In depth interviews will also enable me to clarify any questions which are not understood by the participants (Sarantakos, 2005). Another advantage of in-depth interviews is that I will gain high response rate, with rich, detailed information about the fear of crime among young men. Hence, with in depth interviews it is much easier to discuss sensitive issue compared to when interviewing a group (Miller and Brewer, 2003). Despite these advantages, there are many limitations to in depth interview. With in depth interviews participants may not always be as honest about their fear of crime; hence this will lack reliability (Miller and Brewer, 2003). Another limitation of in depth interview is that it is very time consuming compared to other data collection methods (Seale, 2004). From gaining access to individuals, to conducting the interviews and then analyzing the data will take a huge amount of time (Miller and Brewer, 2003). This is one of the reasons why I will be conducting my research on only thirty individuals. Furthermore, according to May, the researchers physical characteristics such as age, class, race, gender and ethnicity may have an effect on the interviewees responses (May, 2001). This is another limitation as interviews may be affected due to the physical characteristics of the researcher (Sarantakos, 2005). For example, if a female researcher was conducting the study on fear of crime among young men many participants may not be as honest about their attitudes and experiences of fear of crime due to the researcher being a female. Another issue of in depth interview is that people tend to prefer to write about sensitive topics, such as fear of crime rather than discussing the issue in an interview (Sarantakos, 2005). As the study will only be conducted on thirty individuals, another concern is that once the information is gained and analysed, it will be difficult to generalize fear of crime among young men who live in inner London (Sarantakos, 2005). I will now define, discuss and analyse the advantages and limitations of ethnography and why I decided not to use ethnography for my research topic. Ethnography allows researchers to understand the social meanings and activities of people they are conducting research on (Miller and Brewer, 2003). Furthermore, ethnography studies will allow the researcher to observe the participants for a longer period of time (Bryman, 2004). By spending time with the participants, listening and engaging in conversations and getting to know them individually on a daily basis it will help and allow the researcher to have a better understanding of the participants he or she is studying (Bryman, 2004). However, in relation to my research topic my aim objective is to find out the feelings and emotions of fear of crime among young men. With participant observation it will be difficult for me to understand the experiences of fear of crime among young men as the participants may not be able to express their experiences when conducting a participant observation study. Furthermore, when an individual is aware that they are being observed they may behave differently, hence this will lack validity (Bryman, 2004). There are two types of ethnography roles when gaining access to participants, they are known as overt and covert roles. Covert role is whereby an individual discloses the fact that they are a researcher observing the participants for a particular reason. On the other hand, the ethnographer who takes the overt role informs the participants that they are researches (Bryman, 2004). On the whole, covert roles may provide the researcher with more information which is highly valid due to the fact that the participants are not aware that they are being observed. However, by carrying out covert roles you will be breaking the ethical guidelines such as informed consent and deception (Bryman, 2004). I will now define, discuss and analyse the advantages and limitations of using a focus group. Focus groups are when a small group of people are brought together for an interview that share similar experiences and have particular interest. Focus groups have become a very popular method used by many researchers since the 1980s. Focus groups allow participants to ask questions, have discussions and arguments (Bryman, 2004). It also allows participants to justify and articulate their ideas with one another in a group context (Seale, 2004). There are many advantages to having focus groups, by conducting a focus group it will allow individuals to probe one another and challenge each other for holding certain views (Bryman, 2004). Another advantage of using a focus group is that large amount of date can be produced in a short amount of time, however a limitation to this is that it will be difficult for the researcher to record and analyse data from the focus group (Bryman, 2004). Focus groups allow participants to share stories, experiences and thoughts together; hence this provides rich, quality data for the researcher to analyses (Bryman, 2004). Another advantage of a focus group is that it is less time consuming compared to in depth interviews, you can easily get six to ten peoples views and opinions all at the same time rather than interviewing all ten of them (Seale, 2004). Focus groups also allow the participants to listen to other peoples views who have a similar position to them in the community (Sarantakos, 2005). According to Bryman, focus groups are regarded as more naturalistic compared to interviews in the sense that focus groups reflect the processes through which meaning is constructed in everyday life (Bryman, 2004, 348). During the focus group the researcher acts as a facilitator observing the discussion and encouraging participants to contribute (Sarantakos, 2005). Depending on the topic being discussed, focus groups can sometimes encourage the individual to open up and hence take part in the discussion. However, in other situations in-depth interviews are preferred; it all depends on the research topic (Seale, 2004). According to Wilkinson who reviewed more than 200 studies based on focus groups, she found that many researchers fail to analyse and take into account the interaction between the group members (Bryman, 2004). Another critic of a focus group is that some individuals may not express their fear of crime among other young men. By being in a group individuals may not express their true opinions (Sarantakos, 2005). Individuals may feel more comfortable to express their concerns of fear of crime in a one to one interview (Bryman, 2004). In focus groups, individuals may be influenced to follow the group norm and may not open as much compared to in depth interviews (Bryman, 2004). According to Barbour and Kitzinger, focus groups will enable researchers to examine peoples different perspective as they operate within a social network, (Barbour and Kitzinger in Seale, 2004, 181). Furthermore, focus groups may allow the researcher to explore issues which are not easily seen during participant observation (Seale, 2004). However, another concern of using a focus group is that some individuals may dominate the discussion and hence others may not be given the chance to explore their attitudes and feelings towards fear of crime, (Sarantakos, 2005). I will now discuss what sampling method I will use in order to carry out my research. In relation to my research topic and design I will use the purposive sampling method in order to carry out my study. Purposive sampling is when participants are selected due to them having a relation to the subject topic. Purposive sampling is whereby researchers use their expect judgment to find participants who are relevant to their study (Singleton and Straits, 1999). Purposive sampling is a very popular sampling method used by many researchers when conducting qualitative research (Seale, 2004). In relation to my research topic, purposive sampling is the best sampling method to use; it fits in very well with the aims of my research. However, according to Singleton and Straits, a limitation to purposive sampling is that making an informed selection of cases requires considerable knowledge of the population before the sample is drawn (Singleton and Straits, 1999, 159). I will now discuss how I will gain access to my participants. I will gain access to my participants through contacting local organizations who work with youths. I will also gain access by visiting two universities in inner London; I will visit the student union and ask for potential students who are willing to take part in my study. Before the interviews are carried out, I will ensure that I am fully prepared and organised, in order for me to do this I will make a check list of all the things I need to do before the interview and also after the interview. In my research, I will also audio record all the interviews; this will enable me to have a better one to one conversation with my respondents. However, an issue may be that that some respondents may refuse for their voice to be recorded. If this occurs, I will explain to the participants that the interview is only being audio recorded for my use only and that the recording will not be shared with any third party (Bryman, 2004). For the interview to be successful it is vital that the interviewee has an understanding of the subject topic (May, 2001). Before I start my interview, I will define the term fear of crime to my participants in order for them to have a better understanding of the subject topic. Before the interview process, I will make it clear to my participants what is expected of them, by doing this my participants will feel more comfortable and hence more relaxed for the interview to begin (May, 2001). It is important for all researchers to take into consideration ethical issues before conducting any research. The British Sociological Association has set out ethical guidelines for researchers to follow; breaking the guidelines may result in penalties. There are many ethical issues which need to be considered before carrying out a study; however the three main ethical issues are whether there is harm to participants, lack of informed consent, and whether deception is involved (Bryman, 2004). In relation to my study on fear of crime among young men I will ensure that all my participants are fully informed about the study. Before I conduct my research all participants involved will be asked to read and sign the consent forms, all participants will also have the right to withdrew from the study at any given time (Bryman, 2004). Furthermore, in regards to participant harm according to Diener and Crandall, participant harm can be physical harm or personal harm (Diener and Crandall, in Bryman, 2004). I will ensure that in my study none of my participants are physically or emotional harmed. Finally, in regards to deception, I will ensure that all my participants are fully aware of the study and that the results of the interviews will not be shared with anyone else without their consent. Deception usually occurs when the researcher provides false statements to their participants about the study (Bryman, 2004). In conclusion, in depth interview is the best data collection method for me to research the fear of crime among men aged 18-25 living in inner London. Despite its limitations, in relation to my research topic, in depth interview would be the best method to use as it will enable me to understand the attitudes and experiences of fear of crime among young men compared to focus groups and ethnography.

The Physics of Roller Coasters :: Physics

A roller coaster is a thrill ride found in amusement and theme parks. Their history dates back to the 16th century. It all started in Russia, with long, steep wooden slides covered in ice. The idea then traveled to France. Since the warmer climate melted the ice, waxed slides were created instead, eventually adding wheels to the system. The first roller coaster in which the train was attached to the track was in France in 1817, the Russess a Belleville. The first attempt at a loop-the loop was also made in France in the 1850s. It was called the Centrifuge Railway. However, government officials quickly diminished the idea when the first accident occurred. Inventors since then have continued to capitalize on people’s love of a great thrill, always trying to make them bigger, faster and scarier! â€Å"Even though roller coasters propel you through the air, shoot you through tunnels, and zip you down and around many hills and loops, they are quite safe and can prove to be a great way to get scared, feel that sinking feeling in your stomach, and still come out of it wanting to do it all over again (1).† Thanks to the manipulation of gravitational and centripetal forces humans have created one of the most exhilarating attractions. Even though new roller coasters are created continuously in the hope to create breathtaking and terrifying thrills, the fundamental principles of physics remain the same. A roller coaster consists of connected cars that move on tracks due to gravity and momentum. Believe it or not, an engine is not required for most of the ride. The only power source needed is used to get to the top first hill in order to obtain a powerful launch. Physics plays a huge part in the function of roller coasters. Gravity, potential and kinetic energy, centripetal forces, conservation of energy, friction, and acceleration are some of the concepts included. â€Å"A roller coaster is essentially a gravity-powered train (2).† Gravity is the weakest of the four physical forces, but when it comes to roller coasters, it is the dominant one. It is the driving force and what accelerates the train through all the turns and twists. Gravity is what applies a constant downward force on the cars. The deceleration or acceleration mostly depends on the inclination of the angle relative to the ground. The steeper the slope is, the greater the acceleration, and vice versa.

Arcady: His Voyage Towards Individualism Essay -- essays research pape

In the novel Fathers and Sons by Ivan Turgenev, Arcady plays a major role both in his own life and the lives of others. Arcady, despite the shield he surrounds himself with, is not a true Nihilist like his friend Bazarov through his thoughts and actions we see his change. To begin, Arcady shows signs of Romanticism Early on in the novel despite the announcement of his Nihilist beliefs. For example, Bazarov and Arcady were walking one afternoon in the garden and overheard Nicholas playing his cello. "At that instant the lingering notes of a 'cello were wafted towards them from the house . . . and, like honey, the melody flowed through the air" (49). Like a true Nihilist, Bazarov immediately denounced the act of playing music as a purely romantic institution. "Good Lord! At forty-four, a pater familias, in the province of X, playing the 'cello! Bazarov continued to laugh: but, on this occasion, Arcady, though he venerated his mentor, did not even smile" (50). By this we see that although Arcady looks up to Bazarov, he truly does not uphold the Nihilist beliefs as strongly or as strictly. His acceptance of his father's cello playing shows that Arcady, unlike Bazarov. does not find music a purely romantic institution, but an enjoyable way to be merry. Also this incident shows us that Arcady does not like when others poke fun at his family. Here, he obviously does not think his father's cello playing is a laughing matter.Secondly, Nihilist ideas included...

Use of Light and Darkness in Joseph Conrads Heart of Darkness Essa

Use of Light and Darkness in Joseph Conrad's Heart of Darkness  Ã‚      Joseph Conrad's Heart of Darkness contrasts light and darkness, to represent the civilized and uncivilized sides of the world. Conrad uses light to represent the civilized side of humanity while contrasting the dark with the uncivilized and savage. Throughout the thematic stages of the novel, that is the Thames river London, the company's office in Belgium, the journey to the "heart of darkness" and the conclusion, light and dark is used to represent these sides of humanity, but on a deeper level many assumptions of darkness and light are challenged, with the appearance of light and dark, and in turn good and evil contrasting with the reality. From the initial setting, the Thames river, London, on the "cruising yawl" the Nellie, light and darkness are used to symbolize the good and evil side of humanity. Marlow's tale of the Congo is where light and darkness is used to represent the civilized and uncivilized. Marlow talks of the lights that are reflected in the water, creating the idea that the members of the Nellie are civilized. The   lights of London are again used represent the civilized nature of the society, with connotations of "good" coming from the bright lights of civilization. However this is then contrasted with the juxtaposition of the "light", with Marlow saying - "And this also has been one of the dark places of the Earth". By saying this Marlow is portraying London as a city with once the same darkness of civilization, of which the civilized Roman's brought light to. This establishment of light representing the civilized demonstrates the dominant assumptions of the white society, later in the novel it is demonstrated that civilized does no... ...story. However Conrad also challenges many assumptions of darkness being solely associated with evil, and light being solely associated with good, as throughout the novel the light of the white society is critiqued, representing the evil side of humanity.

Data Envelopment Analysis and related literature Essay

As already stated, a rich history of literature and research which is demonstrating the importance of processes in analyzing the performance of an organization exists (Chase, 1981; Chase et al. , 1983; Levitt, 1972; Roth et al. , 1995). Especially, Roth et al. (1995; here and in the following) showed that the key drivers are process capability and execution in an empirical way. It was described in their study that an inappropriate design of certain processes and also the poor execution of a process can lead to process inefficiency, and that both process capabilities and people as major factors affect business performance. When estimating the performance of processes usually a number of different outputs have to be taken into consideration. Data Envelopment Analysis, the estimation method described in this chapter and used as a basis for measuring the efficiency of business processes, deals with these multiple outputs by the use of frontier estimation. In this process, it is specifically determined which relative performance amongst multiple inputs and outputs are present. This in turn is achieved by calculating ratios of weighted outputs to weighted inputs, and the determination of the relative efficiency (which is seen as the distance from a peer object to the best practice frontier) compared with the efficiency of other so-called Decision Making Units (Charnes et al. , 1978). Decision Making Units can be defined as firms or public-sector agencies, but also as single processes or process instances (Sengupta, 1995). Data Envelopment Analysis is therefore used in different areas of daily life, for example in education programs of schools, or the production and retail business (Metters et al. , 2003). The Data Envelopment Analysis method was introduced into the operations research literature by Charnes, Cooper, and Rhodes in 1978 (see Charnes et al. , 1978). They presented it as a new nonparametric (meaning it is entirely based on the observed input-output data and not based on the assumption of a normal (Gaussian) distribution underlying the measured parameters) and multi-factor productivity analysis model (Sengupta, 1995). The Data Envelopment Analysis model as it was originally formulated by Charnes, Cooper and Rhodes, later referred to as the â€Å"CCR model†, has the important and critical characteristic of the reduction of the multi-output, multi-input situation for each Decision Making Unit to that of a single â€Å"actual† output and a single â€Å"actual† input. In fact, the respective measurement of efficiency for a Decision Making Unit is identified by the original Data Envelopment Analysis model by developing the ration of weighted outputs to inputs to 3 he maximum under the assumption that alike ratios for every Decision Making Unit are not larger than one (here and in the following Frei et al. , 1999). This in turn results in a number of efficiency scores less than or equal to one, as well as a reference set of Decision Making Units identified as efficient. The method has also come to be known as the â€Å"input-output oriented model†, because by holding outputs constant and at the same time evaluating to what degree the inputs would have to be changed in order for a Decision Making Unit to be considered an efficient one, the overall efficiency score is determined. The also existing â€Å"output-oriented method† is very alike to the input-oriented method. Using this approach, the ratio of weighted inputs in relation to the outputs is minimized in order to be able to evaluate the actual amount that each Decision Making Unit’s outputs have the chance to be improved whilst holding the inputs on a constant level. In summary, in both cases, a Decision Making Unit identified as efficient has no potential for improvement, whereas as Decision Making Units seen as inefficient have efficiency scores that reflect the actual potential for improvement which is based on the achievement of other Decision Making Units. A proportional (linear) program must be carried out for each of the Decision Making Units to be able to define the relative efficiency scores. Because of the use of a linear function, the implied presumption is that the efficient frontier is piecewise linear. As a fact, the original model of Data Envelopment Analysis comes up with a ranking of the different Decision Making Units in the system in a scale of relative efficiency from the lowest to the highest, where the highest is considered to be one hundred percent efficient (Sengupta, 1995).

Heroism in the Crucible

Mads Szklany English 11 Mr. Doty March 29, 2010 Heroism in The Crucible Often people have to endure tests of character in order to prove who they are. It is when people have to face great opposition that their character is truly shown; we see whether people are heroes or cowards. Those who are heroic always stand up for their morals and never back down and do selfless acts for the good of others. When people encounter moments where they have to face opposition they can do either of two things; they can stand up for what they believe in and do what they think is the right thing to do, or they can sit back and let someone else do it and simply try to ignore the problem. The ones who always stand up for what they believe are the people who are true heroes. People who have a heroic character will constantly rise up and speak out loud when they see that something wrong is going on. The people who are heroes are incredibly important to society, because they are the people who work for a better tomorrow; they are the people who are willing to sacrifice themselves for something better. In The Crucible, by Arthur Miller, there are multiple characters that show the quality of a hero when faced with opposition. I believe that the four characters that showed the most â€Å"hero† quality were john Proctor, Elizabeth Proctor, Rebecca Nurse and Giles Corey. Rebecca Nurse is a good and simple example of someone who is a hero. She is a hero from the beginning to the end of the story. From the start she is willing to sacrifice her own life for her morals, which shown how strong a character she is. Even when she is repeatedly being pleaded by Reverend Hale to confess to witchcraft in order to save her own life, she refuses, because she knows it is a lie and lying is against her good morals. The heroes, Giles and Proctor, are more complex and grow to become heroes in the book. In the beginning of the book Giles Corey does not appear to be a hero. However, throughout the book he begins to play more and more the role of a hero. In the beginning of the book Giles is seen as more of an annoying person who will do bad things to benefit himself, but he changes throughout the book. When the witch hunts start he does not really believe in witchcraft, however, he is still curious about it and wants to ask the expert, Reverend Hale, some questions. Giles accidently makes his wife look like a witch when he starts asking Hale questions. Giles asks Hale about his wife, â€Å"I have waked at night many a time and found her in a corner, readin’ of a book. Now what do I make of that? † (37). It was uncommon for Women to read at this time so it made her look like a witch. Then after this Giles goes on to say, â€Å"It discomfits me! Last night-mark this-I tired and tired and could not say my prayers. And then she close her book and walks out of the house, and suddenly-mark this-I could pray again! † (38). Giles, however, forgets to mention to Reverend Hale that he has only recently started going to church and that he is not very good at saying prayer; he never mentions that this could have something to do with him not knowing how to say a proper prayer. After Giles wife is taking to prison he does not do very much and just keeps on with his life. For the way he spoke of his wife and simply allowed her to go to jail he is definitely no hero. Later, though, Giles starts to notice that even the slightest offhand remark can result in suspicion of one working with the devil. Giles finally wakes up when Putnam’s daughter accuses George Jacobs of witchery. When this happens then Giles notices a motive and claims that Putnam only wants Jacobs’ land. This is when Giles realizes that he needs to take a stand because if he doesn’t then no one will. Giles then rushes to the court shouting that â€Å"Thomas Putnam is only reaching out for land! † (79) Giles claims to have proof and a witness who heard Putnam speak of it. When the court asks him to tell them who the witness is he refuses, because he does not wish to condemn another person, just like he condemned his own wife. Because he will not say who it was, they take him outside and start putting stones on top of him, trying to make him confess. Elizabeth speaks about when Giles was again asked to say who it was. Elizabeth said, â€Å"Great stones they lay upon his chest until he plead aye or nay. They say he give them but two words. â€Å"More weight,† he says. And died† (125). In the end of the book Giles has learned and grown. He dies a hero because he refuses to do the wrong thing; instead he stands up and faces the consequence of doing what is right. From the beginning of the book Proctor knows that the witch trials are only something made up by a group of girls lead by Abigail. He knows because Abigail told him first hand that Betty, who is supposed to be bewitched, is only pretending. Abigail says, â€Å"We were dancin’ in the woods last night, and my uncle leaped in on us. She took fright, is all† (20). Abigail, however, has told the whole town that Betty has been bewitched. When Proctor finds out this information he still does not go to the court because part of him is still in love with his old mistress, Abigail. Later when Abigail begins to accuse Elizabeth, Proctor’s wife, of witchcraft, Proctor has then had enough. He goes to the court and yells to the court that, â€Å"A man may think God sleeps, but God sees everything, I know it now. I beg you, sir, I beg you—see her what she is. . . . She thinks to dance with me on my wife’s grave! And well she might, for I thought of her softly. God help me, I lusted, and there is a promise in such sweat. But all it is a whore’s vengeanceâ€Å" (102). Here Abigail starts to look guilty. Proctor confesses to lechery and if it is true that Proctor did commit lechery with Abigail, then very likely the court will figure out that all this was simply a well-planned plot by Abigail. The court wants Elizabeth to come from the jail and speak to the court in private. When Elizabeth goes to the court she does not know that her husband confessed to lechery. Therefore when Elizabeth is asked about the relationship that Proctor and Abigail had, she merely denies there ever being a relationship between them. She knows that if she lies then she will go to hell, but if she speaks the truth then she will condemn her husband, which she does not wish to do, because of such a selfless act she also becomes a hero. Proctor is the greatest hero in the book. He is also the person in the book who learns the most and grows. He is a very human character because when faced with oppositions he wants to do the right thing, but still has so doubt about what to do; he is a hero, though, because in the end he makes he right decision. He decides to confess, even though his confession is a lie. Then when he is confessing they tell him that he needs to sign his name on a confession. When they ask him to sign his name he begins to cry and refuses to sing, saying, â€Å"Because it is my name! Because I cannot have another in my life! Because I lie and sign mysel f to lies! Because I am not worth the dust on the feet of them that hang! How may I live without my name? I have given you my soul; leave me my name! † (133). Proctor realizes that by him confessing he will be condoning the hanging of all the innocent people. He then decides that he rather stand up for what is right and been hanged, than confessing to a lie. Proctor accepts his fate, Reverend Hale begins plead with him saying â€Å"Man, you will hang! You cannot! † (133). Proctor simply replies with his eyes full of tears, â€Å"I can. And there’s your first marvel that I can. You have made your magic now, for now I do think I see some shred of goodness in John Proctor. Not enough to weave a banner with, but white enough to keep it from such dogs. Elizabeth, in a burst of terror, rushes to him and weeps against his hand. Give them no tear! Tears pleasure them! Show honor nor, show a stony heart and sink them with it! † (133). Then morning comes and Rebecca and Proctor are taking outside to be hanged. When Proctor stands up preparing to be hanged Elizabeth says, â€Å"He have his goodness now† (134). Elizabeth feels that now Proctor has become the great man that he was meant to be. Proctor could have saved his own life but instead he chooses to die because that is the heroic thing to do; he dies for a right cause. The book shows a variety of heroic characters. However, the most important aspect of the book is also that is shows that heroes are not born heroes but they are made into heroes when faced with great opposition. Heroism is one of the most important things in life. Most people lack the qualities of a true hero. Most people are weak and fall when faced with the slightest bit of opposition. That is why heroism should be praised when it is shown. Everyday heroes are those who are willing to do selfless acts for the good of others. Works cited: Miller, Arthur. The Crucible.

The Honorable Nancy Pelosi

I am (Author’s Name); currently the president of the California Nurses Association (CNA) and the overseeing head of its umbrella organization, the Arizona new Registered Nurse (RN) Union called the National Nurses Organizing Committee-Arizona (NNOC-Arizona).I am sending you this letter in connection with a significant health issue in the State of California. This pertains to the apparent incorrect and irresponsible nursing staffing ratio in hospitals and other medical or nursing facilities here in California.This specifically concerns the defiance of the authorized safe ratio in the number of RN-to-patient thereby endangering the welfare and eventually the lives of patients while at the same time hinders our profession’s goal of providing quality nursing care for our patients (â€Å"The Ratio Solution,† 2008).Our profession’s positive position to said measure is substantiated by the fact that the bill supports the mandated RN-to-Patient Ratio which works t o the improvement of patient care by having enough number of RNs. Citing the CNA/NNOC’s Report, the results of a series of scientific researches have proven that the RN-to-Patient Ratio indeed work to the advantage of both nurses and patients (â€Å"The Ratio Solution,† 2008).While similar bills already ensure adherence to RN-to-Patient Ratio, it is an utmost goal that HB 2041 heralds the same objectives in all states of the country.In view of this, I respectfully hope for the Speaker’s full support and eventual endorsement of HB 2041 to the Senate once it is approved by the lower Congress. The Prezelski-sponsored bill aims that the mandated RN-to-Patient Staffing Ratio be guaranteed and that nurses are protected when they spill irregularities in the profession and eventually turned witnesses.I show gratitude to you for finding time to regard our position on this issue. I hope that the above problem concerning the nursing field will be addressed through the supp ort/endorsement of HB 2041 that we earnestly pray from your office.ReferenceCalifornia Nurses Association/ National Nurses Organizing Committee-Arizona.

Cell Membrane Transport

The purposes for these experiments is to be able to understand osmosis and its relationship to tonicity of solutions, and the transportation of molecules across cell membranes. It's also used to understand, and how temperature affects diffusion. You also learn how to test for presences of starches and sugars in solutions. In the first exercise I will be testing for diffusion through an artificial membranes. This one has forty five steps to it. I will not go into it step by step but I'm going to say just the important ones. You need a cup to put 150mL of distilled water in cup number one.Then you soak the dialysis tubing in this cup for five minutes. Then you add in the graduated cylinder, 4mL of distilled water, 2 mL of starch solution, and 2 mL of the glucose solution, then pour it into cup number two. Then use the glass stirring rod to stir the solution in cup two. Then remove the dialysis tubing from cup one, set the cup aside for later, tie up one end tightly. Then test the tubin g with distilled water for any leaks, then pour out the water. Place a funnel at the end of the tubing and then pour the glucose-starch solution into the dialysis tubing from cup two.Then get all of the air out of the tubing and then tie that end securely. Rinse the outside of the tubing to remove what contents could have gotten on the outside of it. Then record the color of solution inside the dialysis tubing. Then use the IKI dropping pipet to slowly add IKI solution to the 150 mL in cup one until it looks like the color of strong tea, stirring with the glass rod while adding the drops. Then record the color of the contents in cup one in before dialysis. Put the dialysis tubing inside cup one, and you let sit for an hour. After the hour, record the color of the dialysis tubing under after dialysis.Then clean cup two and label it dialysis tubing contents. Hold the dialysis tubing over cup two and cut the tubing to release the contents, but save the contents of cup one for later. Th en prepare a hot-water bath, and marking the test tubes numbers one through three. In test tube one add 2 cm of the solution from cup one, and then add 1 cm of Benedict's reagent. In test tube number 2 add the solution from cup two and then add 1 cm of Benedict's reagent. In test tube three add 2 cm of distilled water and then add 1 cm of Benedict's reagent. Record the color of each tube in the before heating column.Place the test tubes in the test tube rack that is inside the hot-water bath, and leave them for about ten minutes. After the ten minutes, use the test tube clamp to remove one at a time and record any color change in the column after heating. This is how you test for diffusion through an artificial membrane. The second test is about diffusion at different temperature using potassium crystals. THe first step is to label three styrofoam cups hot, cold, and ambient. In the cold water cup add two pieces of ice and then fill the cup 3/4 full with tap water.The ambient cup ad d 3/4 water to this cup, and hot water cup add 3/4 full of hot tap water. You let each stand for about five minutes, and then add the temp of each cup to the table. Then label three test tubes and put into test tube rack, using tweezers add about five grains of potassium to each test tube, remember to add the same amount to each one. After this you add 7 mL of water from each cup into a seperate test tube. Remember not to stir when adding water, observe the color of the water in each test tube and record these finding under the 0 minutes in the table. Then place the test tubes inside the cups.After five minutes check the test tubes for the colors of them and then record them in the table. This experiment is to check how the temperature affects the rate of diffusion. In this third experiment we are going to check for tonicity and diffusion. The first step you will add 10mL of distilled water in the graduated cylinder and then one gram of salt to make a sodium chloride solution, then mix well. Mark two test tubes and one and two, filling the first one with distilled water two-thirds full. The second tube add the sodium chloride two-thirds full.After this you will need to cut two pieces of potato about 0.5 cm wide and 7 cm long. Measure each piece and record in the table. Place a piece of potato in each test tube, and wait for an hour. After that hour empty out the water and sodium chloride. The on a paper towel put the piece of potato from the first test tube, distilled water, on the left side of a paper towel, and on the right side place the potato from the sodium chloride solution. Check and see which one is hard and soft. The table makes it easier to keep up with the results of each experiments. In the first experiment there are two tables one for before and after dialysis and the other one is before and after heating.The first table is for recording the changes during dialysis and the second table is for Benedict's Reagent results. These tables help keep tra ck of which one is positive and which one is negative. In the second experiment the table is used for the study of diffusion at different temperatures. You write down the color of the solutions in each tube at the beginning and the second thing is you write the color after five minutes. This one gives the results of how diffusion reacts at different temperatures by color. The third experiment table is to determine the results for tonicity and diffusion.First you write down the dimensions of the slices potatoes before you begin the experiment, in the distilled water column and the sodium chloride solution. Then after the allotted time you take out the slices of potatoes and measure them, and write it down in the after column. Then you determine which is one of the following: tonicity, hypertonic, isotonic, or hypotonic. The observations that I had for the first was how a cell membrane works. The changing of the color in the dialysis tubing was pretty amazing to watch. It was interest ing how the clear solution turned into a dark purple, almost black.Then after the second part of the experiment how they all change from a light blue to either the same color to a yellowish brown. The second experiment is when we use temperature a chemicals to determine diffusion in different states. It just amazes me that so far the main thing that we use is distilled water, except in this one, I used tap water. Sometimes I can smell the chemicals and sometimes I don't. I like this experiment because I don't have to use the stove, I just use the hot water, cold water with ice, and room temperature water. The third experiment is to define tonicity and diffusion.This one was very interesting for me. Even though I had to wait for an hour for the results it was worth it. After you follow the procedure step by step, you get to see the results. After you take the potatoes out of the test tubes, you lay the on a paper towel and you get to feel them. For me this was a more hands on because you got to feel the difference between the two and determine what each one means. In the first experiment there was eight questions to answer starting out with the first one, What is the purpose of this exercise and what is being tested?The answer to this is the purpose is to demonstrate how the dialysis tubing represents the cell membrane, and the discovery of which contains starch. The second question is What color change did you observe in the dialysis tubing and what does that change indicate? It went from a clear liquid to a dark blue almost black and that indicates there is starch present. Another question is Was there a color change in the water around the tubing and if so explain? There was no color change in the surrounding water. What does the Benedict's reagant detect? This detects sugars in the solutions.What does the IKI solution detect? The IKI solution detects starches. The seventh question asks about the similarities of the dialysis tubing and a cell membrane. They both are thin and do not allow molecules to flow through areas they do not belong in. The last question is the transport mechanism in the model cell passive or active and why? I say it is active because it has to constantly not let any molecules pass through. In the second experiment there was only two questions. The first being How does temperature affect the rate of diffusion? With the cold water the potassium just settles at the bottom.The ambient water is a little darker, like a medium pink, and darker on the bottom. While the hot water is dark pink all the way, it is a even color. The third experiment has six questions with the first one being What is the condition of each potato strip after soaking in the test tubes for an hour, and which one in limp and which is crispy? The sizes changed on both, the one that soaked in just distilled water, grew a little bit and was crispy, which means it soaked up water. The sodium chloride got a little smaller, and was limp which means it i s hypertonic.The second question is How would you explain the difference in the conditions of the potato strips using the concept of tonicity? One of them soaked up some water and the other one did not. What was the tonicity of the fresh water solution with respect of the potato cells? It soaked up the water but with it having soaked up just water it didn't soak up any chemicals. What is the tonicity of the salt water solution with respect of the potato cell? In this one it soaked up salt and this made the potato limp. How does the changes in the conditions of the potato strips relate to the wilting of plants?It all depends on what the roots and the plant itself is soaking up, such as chemicals. The last question is How does keeping vegetables cool slow them from wilting? The coolness slows down the process of tonicity and it doesn't soak up moisture from the air. In the first experiment I learned how a cell membrane works and if it can contain starch without contaminating the surro unding areas. The second experiment taught me how different temperatures affect how chemicals react. The third experiment showed me how salt affects the state of the potato and that it can affect other things, too.
