Describe The theme of oppression Essay

The theme of oppression is examined when comparing the literary devices in the poem â€Å"As I Grew Older† by Langston Hughes and the story â€Å"The Loophole Of Retreat† by Harriet A. Jacobs. It is through the use of personification and symbolism that the theme is reflected. The oppression is in just use of authority or power. In the poem â€Å"As I Grew Older† by Langston Hughes describes about a black girl that had a dream, but this dream was slowly disappearing from her. She didn’t have enough freedom and she always wants it to through. The author in the poem is hiding from oppression by hiding in the attic. Also Hughes uses some literary devices such as symbolism and personification. By saying the words the â€Å"wall rose† Langston Hughes showing personification because the wall can’t grow. Then in the second paragraph the â€Å"wall† is represent symbolism. It is symbolizes her dream with a wall because this wall is blocking her happiness and future. In the story â€Å"Loophole Of Retreat† by Harriet A. Jacobs shows the oppression as darkness. He lived in the small garret that he called it as â€Å"den†. It was very dark didn’t have enough air in it and was not for a cold weather. A. Jacobs uses some conflict in the story by saying the words â€Å"I suffered for air even more than for light. It shows us that he wanted to have more freedom and not to depend on anybody. In the poem â€Å"As I Grew Older† by Langston Hughes and the story â€Å"Loophole Of Retreat† by Harriet A. Jacobs use the same theme and the both have oppression. The authors both deal with oppression by breaking through it. Also the both poem and the story have the same ideas and feelings about their problems.

Gladiator: Critical film essay Essay

Ridley Scott’s Gladiator is the critically acclaimed 2000 film starring Russell Crowe which won forty-eight awards, including a BAFTA for best film. Gladiator depicts the tale of Maximus Decimus Meridius and his struggle against the might of the Roman Empire and the vicious gladiatorial arenas. Throughout Scott’s masterpiece are a wide range of filmic techniques in the visual and auditory channels that collaborate in enunciating the overall narrative. The opening sequence is a prime example that uses Mise-en-scene, lighting, costume and film speed to enunciate the key scene. The opening scene begins with some historical information that introduces the audience into the scene and sets up the narrative. Scott informs his audience on the vast scale of the Roman Empire, â€Å"One quarter of the world’s population lived and died under the Caesars.† The emphasis is on â€Å"and died† in order to set the scene for the incoming battle. The Universal and Dre amWorks logos are in a sepia colour. This colour informs the audience that the film is set in the past due to it being used for old photographs and ink. The historical information is accompanied by calming, serene music which leads to the first view of the protagonist. Scott has made use of coloured lighting, incorporating gold (which is representative of the wealth the Roman Empire had) in many scenes throughout the film. The colour gold is an interesting choice because it represents peace and riches which could also be a reference to the Roman afterlife Elysium. Scott has used Mise-en-scene in the first shot of the protagonist, brushing his hand in the corn field. Although the audience are only presented with an extreme close up shot of his hand; they learn about his character through Scott’s control of what appears in the frame. The audience sees a wedding ring on his hand and so learn that he is a family man. The critic John Gibbs also comments on Mise-en scene, â€Å"the contents of the frame and the way they are organised.† During the close-up of the protagonist’s hand, the audience can hear a diegetic sound of the wheat blowing. A non-diegetic sound of children playing and soothing music can also be heard which again tel ls the audience he is a family man with something to loose. The consonant tone of music and golden cornfields set up an idyllic scene of calmness which instantly contrasts when the frame cuts to a harsh, cold and dark Germanic battlefield. The camera uses a medium close up of Maximus’s face which reveals the emotions of a tired soldier. Maximus catches a glimpse of a red  robin which symbolises his near return home to the summer and his family. The robin’s red breast could also be a signifier of the forthcoming bloodshed. When Maximus moves on to greet his army a long shot is used which displays him walking alone. The theme of isolation comes into play which also recurs throughout the film. As the battle scene draws near, a high angle long shot is used to display the mighty Roman army. Costume is used a great deal in Gladiator and adds to the films authentic feel. A medium close up shot is used for the first time on Emperor Marcus Aurelius which shows him wearing rich clothing and surrounded by knights. This scene only lasts a few seconds but the audience discover he is a man of importance through costume. Moreover, Scott wanted Maximus to appear as a strong character that holds high authority as an important character. This is achieved through costume as Maximus’s armour is bigger than all other characters and has different insignias weaved into it. The costume for the barbarian army is rather contrasting to that of the Roman Empire. The barbarians are dressed in rugged cloth which suggests they are not nearly as advanced or wealthy as the Roams who wear steel armour. A Critical Introd uction to Film highlights the importance of costume, â€Å"Costume provides information about time and place, but, more importantly, they express social milieu and personal style.† At 04:41 the barbarian leader steps forward from his army and lunges the head of the Roman messenger into the swampy ground and disrespects the Roman army. This is a casual chain of events that help drive the plot forward, â€Å"Film narration moves forward by a succession of events linked in a casual chain.† It is evident that the Roman army will fight now and Maximus kneels down to run dirt through his hands which is a recurring motif. The motif shows the spiritual side of Maximus, he asks the gods to fight beside him. As Maximus kneels down the audience are given a Point of View shot through Maximus staring into a dog’s eyes. The dog symbolises the brute force of Maximus and suggests he is a wild character. As Gladiator mounts his horse the music quickens and a non-diegetic drum beat begins to enunciate the battle scene. The music increases pace as the battle almost begins which heightens audience’s tension and excitement. As the battle begins a wave of Roman arrows are dispersed and computer generated imagery showcases a variety of special effects. A long range establishing shot on a high angle displays the dest ruction that the Roman Empire is unleashing. As  Gladiator rides with his cavalry there is an array of fast cutting shots that last a few seconds each. The fast paced shots give the audience a battle like feel with exaggerated sound effects of swords clashing and explosions. Maximus demonstrates his leadership role by shouting commands like, â€Å"Stay with me† and â€Å"Hold the line† . After the establishing shots of the battle Scott includes scenes that are more subjective to Gladiator. The gory battle follows Maximus as he enters a slow-motion phase that displays his disorientated point of view of the battle and a montage of his men fighting. Furthermore, the dog also engages in battle which suggests he is strong and independent like Gladiator. Ridley Scott’s Gladiator incorporates brilliant techniques that contribute in enunciating the opening sequence. These techniques are things such as the use of costume which generates an authentic feel and camera speed which demonstrates a terrifying battle. A strong use of Mise-en-scene shows how the narrative develops through camera lighting and casual chains in the plot.

Burton Snowboards: A Marketing Assesment Essay

Snowboarding is a wintertime sport that is rapidly growing in popularity. The founder of the sport, Jack Burton Carpenter, is amazed at the success of the snowboarding market and contributes the success of the market to his determination of foreseeing snowboarding becoming a popular winter sport. The following assignment will describe with specifics the environmental forces influencing the snowboarding industry, the differences in marketing goals in comparison to Burton Snowboarding’s early years with that of today, and will describe each element of Burton Snowboarding’s marketing mix. The environmental forces influencing the snowboarding industry includes the following: Demographic: Baby boomers will retire or have already taken early retirement; therefore recreational activities will increase greatly. Recent retirees will give up most of their spare time, (that was normally set aside for work), for leisure and recreational activities. The snowboarding market is targeting teenagers’ usage of their products. Therefore, if the snowboard industry wants to keep the teenage audience interest in their products they must maintain its image. In order to keep their image safe, the industry must sell to high profit organizations and not low budget markets such as the bi-way, (who knows what the bi-way would want with snowboards but it’s a good example of a low budget market). Economic- Business Cycle: Sales of snowboards will be high during times of prosperity, (when the economy is at its peak). Adding more appeal on snowboards, (examples: a new look, upgrade, new products and more uses for the product), during times of prosperity in the economy will help to expand the snowboard market. Widening the snowboard market makes the consumer more aware of the product and thus adds to the sales on the product. Economy- Inflation: Since the majority of the consumers buying snowboards are teenagers, inflation rates will affect their buying power. Teenagers receive minimum wage and thus will not have adequate funds to purchase a snowboard  for recreational expenditures. Social: People are more concerned then ever about being healthy and fit and more and more people are looking to new unique ways of getting their health needs met. Location: The snowboarding market must be situated in or around accessible snowboarding facilities or areas. E.g. Ski resorts, mountainous regions and places that receive an adequate amount of snowfall. The elements of marketing mix that Burton snowboards cover includes price, product, and distribution, marketing communications and customer service. The following is a more specific outline of each of the marketing mix elements. Price: Burton Snowboards range from $300-$1000, more expensive then low named brands but shows that quality, effort and workmanship has been placed into the creation of each individual board. Product: Burton added a new line of protection equipment for the upcoming snowboarding season, including such products as: styling helmets, pads and hats. The helmets are improved from last year’s models and now contain: venting ports, micro fit adjustments, a wide-angle view (for safety) and removable earpieces. Distributions: Burton snowboards can be purchased at any local retail that specializes in snowboards, (the locations nearest us includes: Sports Swap 2045 Young Street and Sporting Life 2454 Young Street), and at ski resorts allowing snowboarders (rental only). Marketing Communications: Burton Snowboarding has created an image that is appealing to teenagers. Burton is using this image to attract this age group by advertisements, Internet sites, and articles in popular teen magazines and by sponsoring local youth events. Customer Service: Burton Snowboarding has created a safer snowboarding experience for its users, by introducing safety products such as helmets and pads. In the early years of developing the snow boarding industry, Burton tried to gain acceptance from fellow skiers. Burton tried to persuade ski resorts of allowing snowboarders to use their ski resorts. Burton got its big break in 1983 when Vermont Stratton Mountain allowed snowboarders to use its slopes. Burton hoped that by opening opportunities to snowboarders on ski resorts that the sport would gain acceptance from the consumer, and thus open the snowboarding market.Burton is now at the leading edge of snowboarding, and its products cover the largest variety of boards, ranging from: Free riders, pipe boards, novice and expert lines of boards. Burton also sells snowboarding equipment along with its line of boards; this helps with consumer’s convenience and helps to gain more profit for the company. Burton has put together a non-profit organization that helps under privileged kids learn to snowboard. All equipment and professional instructing are available. Burton hopes to promote the product and show the consumer that it cares about the community, all which will reach more target markets

Power of Higher Authority in significant relevance to Antigone by Essay

Power of Higher Authority in significant relevance to Antigone by Sophocles and Another Antigone by A.R Gurney - Essay Example The modern adaptation for theatre by A.R. Gurney offers an interesting contextualization of heroine Antigone’s fight against authority. In both the cases, the theme is the same, one of confrontation of the individual will against a powerful authority figure. In Sophocles’ Antigone, this antagonist was Creon the King. In Gurney’s play it is the Professor in Classics Department George Henry Harper. But the nature of struggle of the two heroines is the same. This essay will argue that the depiction of the power of Higher Authority is crucial to the dramatization and moral deliberation of the two plays. Professor Henry Harper is equated to the all powerful Creon of Sophocles’ conception. To match with his role as an intimidator Harper is given a grizzly white beard by author Gurney. The University of Boston and its hierarchy of administrators provide the power structure for Another Antigone, with Henry Harper assuming a key position of power within in the Depa rtment of Classics. He is a tragicomic character in an academic environment that is struggling with reduced government funding and decreasing student enthusiasm. It is in this backdrop that Judy Miller plays out her tryst with power. (Diski 49) Miller, a candidate for valedictorian, presents her bold reworking of Antigone in blank verse form in the place of a formal term paper. Taken aback by this disrespect for rules, the professor exclaims â€Å"Another Antigone!" in reference to both the work being presented and its author. At this point a antagonistic position of the rebellious student and her convention respecting professor is established. In Sophocles’ Antigone, by contrast, the confrontation between Antigone and her uncle Creon (the ruler of Thebes) begins with the demise of her two brothers Eteocles and Polyneices. Since Creon was on the side of Eteocles during the combat between the two brothers, he decrees to honor him in death. In sharp contrast he decrees that Po lyneices be left rotting in the battle field sans a proper burial. This is the highest form of punishment in ancient Greek and its evocation is a measure of Creon’s hostility toward Polyneices. (Botton 20) In Creon’s own view, what legitimizes his decree is his authority as the supreme ruler of Thebes. He performs very little moral deliberation before setting his order to execution. It is unfair to compare Creon with Gurvey’s Harper, for the latter is not so much arrogant as formal and conservative. Henry Harper’s power in the University is nowhere near equal to that wielded by Creon, the emperor of Thebes. Hence, although the two authority figures share a position of prestige and power, their personalities and purviews are very different. The overbearing undergrad Antigone, Ms. Miller, has â€Å"as great an irrational self-confidence in her thespian powers as Shakespeare's Bottom, and when Henry Harper, that old Creon, refuses to give her play at least a B, she launches a campaign against him, including charges of anti-Semitism, that leads to a proper catastrophe.† (Disch 174) But in Sophocles’ classic, Polyneices’ beloved sister Antigone is a balanced, intellectual and humane person (as evidenced from allusions in the play). Her love for her brother impels her to bury him properly. Though this action would invoke the wrath of Creon and jeopardize her life, her humanity and love supersedes all other considerations. Antigone believes that though she may die as a consequence

Starting a Business Online, Part 2 Term Paper Example | Topics and Well Written Essays - 1000 words

Starting a Business Online, Part 2 - Term Paper Example Selling the company’s domain is like selling what you have worked for years to build the business and letting your customer’s trust be put unto other’s hands. What if the new user of the domain will use the name for fraud or malicious intent? What will happen to your business and your credibility? What will happen to your customers? These are just few of the questions to ask on whether the domain should be sold or not. But for me, I value our efforts for years, thus I will not sell our domain. .   Functions of E-commerce Softwares: Catalog Display, Shopping Cart, Transaction Processing It is important to provide a catalog display in e-Commerce software. A catalog includes a display or list of goods and services available in the business. In a small local clothing store, the most common catalog service used is the static catalog (Electronic Software, n.d.). In a static catalog, it uses a HTML format to create a simple list appearing on a web page (Electronic Sof tware, n.d.). This software is very important especially for a small online store because it serves as the frontliner of the business. The only way for the customer to be able to know your offered goods and services is to check your web page. It is the most convenient way to offer your products. The customers need not send you email or contact you for questions regarding your business. Shopping cart software makes it convenient for customers to shop in your online business because it eliminates filling out online forms for the products or services that the customers wanted to purchase in your online store. Today, this software also called shopping bag or shopping basket keeps track of the selected products purchased by the customer wherein they can view their shopping list and they can add or delete items on the list (Electronic Software, n.d.). By simply clicking on the item, all the necessary details such a sthe price, the product code and quantity are stored in the cart. Another important software in electronic commerce is the transaction processing. This occurs when a customer clicks the checkout button, the software performs all the necessary calculations such as discounts, tax and shipping cost (Electronic Software, n.d.). Both the customer and seller’s web server switch into a secure state of communication (Electronic Software, n.d.). This is a very important and complex software where it needs update every now and then especially on taxes and shipping computations.

Living a Fast-Paced Life Style Essay Example | Topics and Well Written Essays - 500 words

Living a Fast-Paced Life Style - Essay Example For some people, working all the time is a rush, a â€Å"natural high.† They like waiting until the last second so they have to crunch to get things done. They enjoy working at the 11th hour. Feeling the pressure that they know they need to get the work done, they are able to get it done quickly and efficiently, much more so then if they weren’t working against the ever-ticking clock. Also, some people like being busy, and would rather have a million of things to do then to have to sit around and do nothing. Some people find a pile of paperwork more refreshing than a break, and would rather have to speedily work around the clock then sit and be idle. They are the â€Å"busy bees† of our society, and they keep working even when they don’t have to, working all the time quickly is their passion and their love for life is lived through it. There are also negatives to living such fast paces live style. If you are constantly in motion, you tend to wear out quickly, as discussed in "Burned Out and Bored" by Ronald Dahl. If you are not moving all the time you can become bored, and you also can miss out on the finer things in life. Ronald Dahl also discusses the problem of sleep deprivation becoming a habit for kids who are constantly seeking the next exciting thing to do when they find a time, and sometimes compromise sleep for this. Bad habits like this, he says, can be hard to break later in life. People can also become moody, and emotional problems can arise from always being in motion. On the other hand, I believe you need a balance. I find it is nice to sometimes have a lot of work that needs to get done, as it helps me work quickly and efficiently. I also, however, find that I need time to just be alone and chill sometimes. This helps be receive both the benefits of being in a fast-paced world, as well as the benefits of slowing down when I need to.

Summary Assignment Example | Topics and Well Written Essays - 250 words - 41

Summary - Assignment Example The author has urged that the simulations should be closer to real world scenarios. The author states that heavy dependence on automation of flights is leading to underdevelopment and erosion of manual skills required to handle flights. The author even concludes that lack of training to handle flights manually is one of the causes of accidents. As a marketer I have learned through this article that such articles and the conference in which the speaker talked about all the issues related to training and automation of fights can send a negative image of the airlines in the minds of the consumers. The consumers may think that the pilots are not equipped to handle flights manually and pose a risk to their life. On the other hand, marketer of an air flight organization that have already been providing proper training on how to handle the flights manually can use similar issues to develop a positive image of themselves in the eyes of the

Doccumented Essay Using No Name Woman from the Norton Anthology

Doccumented Using No Name Woman from the Norton Anthology seventh Edition and THREE (3) other sources from shcolarly journals - Essay Example This voice comes forward in her short story â€Å"No Name Woman† to tell of a family legend that has helped to shape the woman she would become. In her speculations about what might have pushed the no name woman to a position of suicide and her subsequent disownment by the family, Kingston, as narrator, reveals a great deal about the social and cultural positions of her dual society. The story, told in first person, is presented as an autobiographical reflection upon a story told to Kingston by her mother when she first reached puberty. Essentially, the mother tells Kingston about an aunt she had that is no longer acknowledged or remembered (out loud) by the family. This aunt was married quickly to a young man who was leaving China for America to try to earn money.

Years after their departure, though, this aunt became pregnant, bringing disgrace upon the family. As the time for the baby’s birth draws close, the village rises up against the family that has brought so much shame and dishonor to their community, attacking the family home and destroying their property. The rice fields are trampled and drained, the doors are broken in, the kitchenware is smashed and the villagers act in ways calculated to instill terror in the hearts of thos e inside. After the villagers are gone and the family is left to salvage whatever shattered pieces of their lives that are left to them, the pregnant aunt ran out into the fields and, later that night, gave birth to her baby in a nearby pigsty. Kingston’s mother later finds the girl and her newborn child drowned in the family well. The remainder of the story is Kingston’s reflections upon this aunt as she attempts to understand why she would have risked so much simply for sex. There are several massive holes in the story of the no name aunt for

Explain the development of the US Airline Industry and what role did Essay

Explain the development of the US Airline Industry and what role did the government play from 1910-1950 - Essay Example It was the world’s first commercial flight which travelled from St. Petersburg to Tampa Bay. The earliest initiative to promote the US airline industry was the formation of the National Advisory Committee for Aeronautics in 1915(NACA). This body was funded by the government to research into aircraft design and it was able to create the first supersonic aircraft. NACA was later integrated with NASA. With high speed aircrafts, airplanes began to be seen as an alternative to trains and roads. The major reason behind the evolution of this industry was the United States Postal Service. The USPS used army services during the early 1920 but since the army was involved in the World War, it could not render much time to the postal service (US Air). In 1925, government passed the Air mail act which allowed the private airlines to carry postal mails. The government took this step because it believed that it would promote the airline industry in the country and also provide economical sup port to the country (Harry, 2004). This served as a great initiative and the number of flights rose to a considerably large level. The private airlines expanded under this act and soon a large number of airlines were operating which not only for delivered postal mails but also offered passenger services. However with the increased number of flights and no monitoring and regulatory body, the accidents were very common.

Cementless Fixation of Total Hip Replacements Essay

Cementless Fixation of Total Hip Replacements - Essay Example Literature supporting or refuting both philosophies is available. Cemented fixation - Cemented stems have a variety of smooth, textured, and coated surfaces that bond to a layer of cement. These stems occupy 80% of the medullary canal to allow for a mantle (ie, cement-occupied space). A centralizer is added to many cemented stems to keep the stem in the center of the canal, which provides a uniform space for the cement around the implant. (Canale, 1998, 314). Differing philosophies guide surgeons in selecting cemented femoral implants for patients. There was a trend in the 1980s to use more cementless implants; in the 1990s, cemented implants regained popularity. Currently, surgeons are favoring cementless techniques again as a result of proven extended service life in long-term outcome studies on porous implants. Cement is indicated when a patient's bone quality cannot be stabilized satisfactorily with a cement-less implant (Wheeless', 2003). The basic principle of uncemented fixation is that the initial stability of an implant is achieved by mechanical interlock and initial apposition of implant surfaces to host bone is converted to long-term stability by the ingrowth/ongrowth of a stable biological interface (Bloebaum etal, 1997) Cementless or pressfit fixation - with use of cemented impant systems, problems related to cement fixation, including loosening, bone loss, and signs of fragmented cement, were identified. Research efforts led to fixation without cement by using femoral stems tightly fit into the canal. This technique often is referred to as pressfit. Pressfit femoral stems have a porous surface that allows bone ingrowth into the stem, referred to as biological fixation (Hoffmann, 2000). One of the coating systems for implants is calcium phosphate-based material called calcium hydroxyapatite. Hydroxyapatite is the inorganic phase of bone, is inherently compatible with the body, and has been shown to promote bone growth and enhance implant fixation (Geesink etal, 1987). It is used as an additional way to bond bone biologically to a stem and cup. These stems provide immediate implant stability and fit tightly to the endosteal cavity of the proximal femur. There are four basic shapes for press-fit femoral stems-anatomical (ie, bowed), modular, straight, and tapered (Canale, 1998, 315, Hoffmann etal, 2000). The anatomical stem has experienced increased popularity and market growth as a result of excellent long-term results documented in the literature (Hoffmann etal, 2000). The porous coated stem previously was indicated for use in active, young patients and for revision of cemented hips, but now surgeons are using pressfit stems in patients of all ages who have good bone stock (S Rapp, 2003, 14). Physiology of the cementless system Micromotion of 20 m or less at the bone-implant interface will create an environment in which stable bone ingrowth can occur, that motions of 40 m lead to less stable interfaces, and that motions of 150 mm will prevent this

Police Corruption Essay Essay Example for Free

Police Corruption Essay Essay Police Corruption can be defined as a form of police misconduct in which law enforcement officers break their social contract and abuse their power for personal or department gain. There are three forms of police corruption. These forms are Nonfeasance, which involves failure to perform legal duty, another form is Misfeasance, which is failure to perform legal duty in a proper manner, and the third form is Malfeasance, which is commission of an illegal act. The three explanations of corruption are the â€Å"rotten apples†, â€Å"departmental†, and the other focuses on factors external to the department. An example of these would be an officer might feel unappreciated for their good work and actions and it might make them corruptible. An example of departmental explanation would be if officers feel uncommitted and unsupported, their outlooks and values are reinforced by others in the group which may lead to lack of commitment in their job, thereby leading to corruption. Some police officers may abuse their power because they see themselves as not enforcers of the law, but them as the law itself. The â€Å"blue wall of silence† is a term used in the United States to denote the unwritten rule that exists among officers, where they should not report on a colleague’s misconduct, errors, or crimes. This may impact an officer’s loyalty to their profession because they are not doing their job if they are letting another officer get away with crimes, and if they did report it then they would be breaking their loyalty to fellow cops. It’s important for officers to have a good ethical foundation before they enter into this job because it would help prevent them from doing wrong and abusing their power. In the â€Å"Stopped for Being a Mutt† video, I realized how bad some officers can act sometimes. The teen was stopped and questioned multiple times for looking suspicious, when really they were just racist. They were trying to provoke the teenager to justify an arrest. I feel the form of police corruption they were doing was misfeasance. Stopping someone because of their race, when they weren’t committing any crimes is humiliating to that person and is wrong of any cop to abuse their power in this way. The â€Å"Blue wall of silence† comes up in this type of situation because some other cops  witness it and knows that this goes on when officers have low numbers of stops, and they don’t want to tell because they don’t want to seem disloyal to their fellow police officers. In the â€Å"Los Angeles Police Department† video, they talked about the Rampart and Crash scandal. When I watched this video I was in disbelief that, that many officers were implicated in some form of misconduct. I understand that they wanted to get gangs and crimes off the street but this was no way of going about it. They would shoot or beat people when they were unprovoked. They would steal narcotics and plant false evidence, and frame suspects and cover up all that these officers were doing because it was getting rid of the gangs and â€Å"hoodlums†. I can’t understand how these officers didn’t think what they were doing was wrong and immoral. This form of corruption in this particular situation was malfeasance. What they were doing was illegal, and they are here to protect and obey the law. In the â€Å"Behind the Blue Wall† video. I was extremely shocked to see the police brutality that occurred in these cases. I don’t understand how an officer could deliberately torment a victim because of their race and think they can get away with what they’re doing and that it isn’t wrong. Malfeasance is the form of corruption that comes up in these cases because what they are doing is illegal. The unlawful beatings and shootings of these victims, when they are not provoking the officers; is completely wrong and these cases need to stop. The Blue wall of silence also comes up in these cases because there were officers who knew about what happened and what the other officers were doing and instead of reporting it, they attempted to cover it up. Co-workers should treat those who inform authorities of illegal activity in the police agency the same as how they treated them before they reported corruption. In the virtue ethics perspective, the habit of right desire, he was making the right choice by reporting corruption because he knew that what was going on in the agency wasn’t right and needed to be stopped. Frank Serpico’s response to this case was â€Å"It’s always worth it to be at peace with yourself.† I think this does imply reasoning of ethical thought. I  think Serpico meant that, as long as you feel good with what you are doing, and you are doing what you think is right, then that is all the matters. I agree with this because no matter what happens in the end, it is all worth it if you are at peace and happy with what you did. There are conflicts presented in terms of loyalty and duty. Loyalty is a good to have, but it is not a virtue. If loyalty is treated as a virtue, it can be misguided. It will lead to protection of illegal conduct and can turn into corruption. Officers may want to be loyal to fellow officers and not report what is really going on, however they also want to do their duty, and want to report because it is their duty to not participate in the corruption. The blue wall of silence impacts conflicting loyalty because it is an unwritten rule amongst officers to not report a fellow officer’s mistakes, misconducts, or crimes. This affects them if they want to be loyal to those officers and be loyal to their civic duty as well. If I was an officer in this situation, I would definitely report these crimes. I don’t believe in the blue wall of silence. I think that if an officer is doing something illegal then it needs to be reported and dealt with. Just because they are officers doesn’t mean they should be able to get away with things that they are arresting other citizens for doing.

Hannah and Her Sisters Essay Example for Free

Hannah and Her Sisters Essay Relationships in New York are as complex as the city itself. Nothing can be considered as sedentary because of the always changing temperaments of people, development in the place and other factors that contribute to change. It is surprising though that no matter how complex human relationships are; people (in New York) seem not to take it heavily. It may be because of their fast paced lifestyle that they don’t see the heavy impact of certain situations unless it has something to do with career goals. In the movie Hannah and Her Sisters, Woody Allen used comic archetypes to satirize relationships on New York City by exaggerating the kind of intricate relationships and character’s reactions towards situations in a comical way. He showed that people have the tendency not to care how absurd their relationships with others are as long as they maintain their image and keep up with their goals. The story revolved around the intertwined relationships of three sisters with their husbands and exes. To some cultures (other states), the circumstances that the sisters got into may not be dealt as light as they did. To others, the family might condemn the husband if he falls in love with his wife’s sister because it will cause conflicts between the sisters. Woody Allen made the characters in the movie treat the state of affairs in a romantic and funny way. Through the movie, Woody Allen showed that relationships in New York are that complicated however, people generally manage to maintain a positive outlook in life. It is noticeable that in the movie, Allen imposed a happy ending when all of the sisters are happily married.

Reflective Account: Ethical Dilemma Treating Cancer

Reflective Account: Ethical Dilemma Treating Cancer This reflective account will discuss an ethical dilemma which arose during a placement within a community setting. To assist the reflection process, the Gibbs (1988) Reflective Cycle which encompasses 6 stages; description, thoughts and feelings, evaluation, analysis, conclusion and action plan will be used which will improve and strengthen my nursing skills by continuously learning from both good and bad experiences, and develop my self confidence in relation to caring for others (Siviter 2008). To comply with the Nursing and Midwifery Code of Conduct (NMC) (2008) and maintain confidentiality all names have been changed and therefore for the purpose of this reflection the patient will be referred to as Bob. Bob is a forty four year old man who has been receiving aggressive and invasive treatment for several months in the form of chemotherapy in an attempt to cure his Hodgkinsons lymphoma cancer. Throughout the treatment Bob remained positive that he would be able to put the worries behind him and live a normal life with his partner and teenage daughter. However, Bob was unable to control his body temperature, which was a possible sign the chemotherapy had not been successful and was offered further investigations to establish his prognosis. Whilst my mentor who is a Community Matron, was talking to Bob, his partner Sue took me to one side and asked me if the investigations revealed bad news would it be possible to withhold this information from Bob because she felt he would not be able to deal with a poor prognosis and would give up hope. Prior to Bobs original admission the possibility of f the chemotherapy failing was discussed but he refused to consider this was an option and was convinced the condition could be treated successfully. I explained to Sue that this situation was outside of my area of expertise but with her permission would discuss it with my mentor and ask her to contact Sue at a mutually convenient time to discuss further. My mentor contacted Sue and advised her that she would discuss the situation with Bobs Consultant once they had received the results of his tests. However, my mentor diplomatically informed Sue that she has no legal right to insist that information be kept from Robert (Dimond 2005). As expected Bobs test results concluded the chemotherapy treatment was unsuccessful. Considering what he knew of Bob, the consultant agreed it would be advantageous to withhold the diagnosis from him. Therefore it was agreed to discuss Bobs test results with his partner. Thoughts and feelings In the first instance I felt that the Consultant was ethically wrong to withhold the results of the investigations from Bob and not necessarily acting in his best interests. I felt that in order to ensure Bobs rights were protected and to give him the opportunity to be involved in his own plan of care he should be informed of the outcome of the tests. Bob had the capacity to consent and as during my placement would be acting as an advocate for him. I felt that if I was in Bobs position, I would want to know what the outcome of any investigations were and it did not seen right that the diagnosis would be documented in his records and his family and possibly friends around him would be aware of his diagnosis whilst he was kept in the dark. I felt that if we were to visit on a regular basis that I would feel very uncomfortable knowing something that had been kept from him and possibly have to lie to him or avoid answering directly when asked difficult questions. I felt that I would be a ble to have a better relationship and understand the care he wanted if he was told the truth about his condition. I also felt that his family were taking denying him the right to autonomy and th right to make informed choices in his end of life care. Analysis The situation was complex in terms of ethical principles. It was not just a matter of clinical practices but providing the best holistic care to Bob during his forthcoming terminal illness. This situation gave rise to multi-disciplinary team discussions to assess whether the diagnosis should have been delivered to Bob. Standing back from the situation, I realize that my own feelings were perhaps judgmental and that I should have taken a more holistic approach rather than just clinical. It also made me aware of the importance of promoting advance directives to patients in situations where an illness may lead to terminal care Evaluation Today patient autonomy is a highly regarded principle that healthcare professionals promote at all times and is fundamental for all patient interactions of which telling the truth to a patient about their diagnosis and prognosis is part (Dimond 2005). Lo (2009) says to be totally autonomous competent patients have to be told the nature of their illness, recovery prospects, how their illness will develop, treatments available and the consequences of any such treatments to enable them to make an informed choice in order to grant consent to treatment of their choice or refuse treatment they do not want. However this has not always been the case, traditionally, paternalism, where the doctor alone would make a decision about whether or not to inform their patient of the diagnosis used to be the preferred method of treating and caring for patients (Lo B 2009). It is only over the past 20 years or so where it is the norm to share decision making with the patient to enable them to make informed choices in their preferred care and treatment (Boyle 1995). However not all patients want to know their prognosis or take part in their end of terminal treatment and care. A study which took place in 1995 concluded that some ethnic groups were less likely to approve of truth telling in respect of diagnosis than others (Blackwell 1995). The UK is culturally diverse and not all patients and families want or accept autonomy. When a person is sick in some cultures, the family prefers to take responsibility for the medical decisions and often wish to receive the diagnosis and nursing plan before the patient. Although this is often the case within Chinese and Japanese cultures, it does not automatically mean that the request to withhold diagnosis from the patient will be upheld. To add to this complex issue, there may be differences within these cultures, such as recent immigrants and older family members wishing to adhere to cultural traditions and younger family members wishing to practice autonomy (Lo B 2009). Advanced care directives definition are used to enable a person to have autonomy. These ethicalBarbosa da Silva (2002) defines an ethical dilemma as: A situation where a person experiences a conflict where he or she is obliged to perform two or more duties, but realizes that whoever action he or she chooses will be an ethically wrog one. Many experts agree healthcare professionals are faced with many ethical dilemmas when caring for terminally ill cancer patients. Communicating the diagnosis and subsequent prognosis is one of the most common (Kuupelomaki and Lauri 1998)(Roy and MacDonald 1998). It is not unusual for relatives to ask a Consultant to withhold information (Alexander et al 2006) which Kenworthy et al (2002) says family members request out of compassion and love. However, (2006) disagrees and suggests it is often the relatives who are unable to cope and have difficulty coming to terms with the impending prognosis. Dimond (2005) suggests withholding the truth can be harmful or lead to a conspiracy of silence but may be justifiable if it is in the patients best interest not to know. In agreement, Lo (2009) points out receiving bad news can have a negative and drastic effect on a patients view of their future. Nurses have a duty in accordance with their professional code of conduct to act as a patients advocate. Whatever their personal thoughts are in relation to withholding diagnosis from a patient, if the Consultant deems it in the best interest of the patient then a nurse has a duty to adhere to the Consultants decision (Dimond 2005).However Georges and Grypdonk 2002 suggest this can lead to nurses feeling powerless, frustrated and concern when involved in palliative care. Evidence suggests that if a Consultant establishes it is not advisable to inform the patient of the diagnosis or prognosis then it is right to give information to the family (Rumbold 2006). Dimond (2005) states patients have no legal rights to information and therefore if a Consultants believes it is in the best interest of the patient they can refuse to give a diagnosis to them. However, some would argue to withhold information would be considered paternalism (Lo B 2009). Paternalism is when an individual, in this case the Consultant, believes they are in a position to act in the best interest of another individual. Although Bobs welfare is key, the consultant has taken away his right to his autonomy to make future healthcare choices including important end of life decisions by making the decision not to inform him of his diagnosis (Sandman and Munthe 2010). Tingle and Cribb (2005) define this as hard paternalism as opposed to soft paternalism in which Bob would not have the capacity to make an informed decision regarding treatment and care following his diagnosis. The may be in beneficience to the patient but conflicts with autonomy. While considering the decision to not tell Bob the truth regarding his diagnosis, the consultant would have taken into account the ethical principles of beneficence (to do good) and non-malifience (to cause no harm) (Dimond 2005). In Rumbolds (2006) opinion it is wrong to not tell the truth or withhold information from a patient as it denies the patient autonomy and is in conflict with the ethical principles of beneficence and non-malificience. Research carried out by Sullivan (2001) suggests patients believe that Doctors should tell them the truth with a staggering ninety nine per cent of patients wanting to be informed of their diagnosis. However there is evidence to suggest the consultant was right to withhold diagnosis as it can initiate denial, and cause the patient psychological damage (Kenworthy et al 2002). Patients react differently to bad news and Elliott and Oliver (2007) suggests information should given slowly enabling the patient to have enough time to absorb the information given. Sadness, despair, anxiety and depression are feelings patients suffer when faced with life threatening illness. >believes that if healthcare professionals have an open and honest relationship with their patients it enables greater trust (Elliott and Oliver 2007). Bowers and Arnold (2010) agrees with this and adds that an open relationship based on trust enables healthcare professionals to support patients to be in control and make preferred choices with issues relating to their end of life care. However, Kenworthy, Snowley, Gilling (2002) are in disagreement with these statement say to force a patient into to face the trust regarding their diagnosis is both unethical wrong and damaging. Millard and Florin (2006) (nursingtimes) says that patients have different needs which can often be complex and it is important to recognise that some patients choose not be involved, that some individuals do not want to be part of their care but put their trust in health care professionals who are t rained in what they do. Elliott and Oliver (2007) states that a hope is fundamental to a terminally ill persons wellbeing and as such is something to be protected. She adds that hope of a cure whilst facing a terminal illness is an individuals right and helps them to face the final stages of life and points out that if hope is taken away it leaves a patient with only fear. Conclusion This experience has made me aware that good listening, hearing and communication skills are vital to gain a holistic view when dealing with patients and close ones in end of life care. It is also important to liaise with other members of the multi-disciplinary team to ensure that the best possible approach and care is delivered to the patient. It is important not to be judgemental but to incorporate all issues when taking a holistiv view in order to make the right decision. As this was my first experience of end of life care in the community, I was in unfamiliar surroundings and as such not experienced enough to make the right decision in Bobs case. The consultant was correct in determining that Bob was not in a position to accept a poor diagnosis and therefore withholding the information was the correct decision. Action Plan. My action plan is to promote advanced decision and power of attorney Assess holistically and taken into account I also feel than advance directives may have cleared some of this issues and will read about their importance in would have resolved some of this issues and read about their importance and promote their importance when the opportunity arises However, the circumstances surrounding this decision could only be applied to Bobs situation. I believe that as a Nurse I will be involved in ethical dilemmas again however I feel that now I my decisions will be based on each unique patient recognising their own individual needs and wants. Delegation This essay is a reflection of a situation I came across whilst on Community Placement. To assist with this process, Driscolls model of reflection will be used to focus my thought processes whilst learning. Driscolls is a straight forward model which encourages one to return to a situation to understand it better and improve future experiences (Driscoll 2000). To comply with the Nursing and Midwifery Code of Conduct (NMC) (2008) and protect the confidentiality of patients pseudonyms have been used throughout. As required by the first stage of Driscolls model I will describe the event s which took place whilst my mentor was on annual leave and I was assigned to Dianne, another district nurse within the community team. The reason I have decided to return to this situation is because registered nurses should ensure their practice does not compromise duty of care to individuals and at the time I felt that Dianne was delegating duties inappropriately and therefore may have been in breach of NMC requirements (NMC 2004). Whilst assigning the days work Dianne said that it would be a good opportunity for my personal development to go out unsupervised to visit patients within the area to carry out their care and treatment. I was asked to visit a 92 year old patient called Rose who the team visited on two or three times a week to treat a couple of problems. Firstly, she had ulcerated legs which the team were treating with four layer compression bandaging which evidence suggests is the best way to encourage venous return in order to maximise the healing process (OMeara et al 2009). Secondly she had a small sacrum sinus which was packed and redressed. Diannes request put me in an awkward position as I had visited Rose on a number of occasions with my mentor and with her supervision had been able to assess, treat and care for Roses problems appropriately with the exception of applying compression bandages as my mentor had explained to me were only to be applied by staff who had received appropriate training . I am keen to take advantage of any professional development opportunities and improve my clinical skills. However I felt that although I was able to manage most of the delivery of care to Rose as required by the NMC Code of Conduct (2008) applying the compression bandaging was outside my remit and would have been unsafe practice. My feelings were that Dianne was not doing this for my personal development but for her own personal reasons resulting in her abdicating her responsibilities. She did not ask me how I felt about attending patients without supervision or check I had the necessary clinical skills. With this in mind I agreed I would visit Rose, take down her dressings, assess and debride the wound, apply appropriate dressings and the first two layers of bandages. However I requested that Dianne called in after me to apply the compression bandages. Dianne did not appear to be very happy with my request but reluctantly agreed. When I arrived at Roses I introduced myself and explained the purpose of my visit and that Dianne would follow me to apply the compression bandages. I explained at each stage what I was doing, to put Rose at ease, remembering look up and face Rose, so that she could hear clearly what I was saying or read my lips and facial expression as she was partially deaf. As agreed with Dianne I took down the existing dressings, debrided and assessed the wound against the current wound care plan. The wound bed had reduced considerably and although an Inodine dressing had been applied previously, the wound had dried considerably and in my opinion did not require replacing. Therefore I telephone Dianne to let her know of my assessment and it was agreed to dress the wound with a simple NA dressing before bandaging. Whilst at Roses I took the opportunity to update the wound care plan and therefore documented the size of the wound, excudate, smell etc etc and documented all my findings and actions in the care plan. Whilst at Roses I also required to redress the sacral sinus in accordance with her care plan. When assessing the wound I noticed that although her skin was not broken, her sacrum was very red. I had also previously noticed that although she had a pressure cushion sitting on another chair I had never actually seen her sat on it. Therefore I took the opportunity to encourage her to become involved in promoting her own health and explained that her sacrum was very red and that as she sat for long periods of time, it was possibly that her skin would break down, which was why she had been issued with a pressure cushion. We discussed why she did not use the pressure cushion, she said that she did not find it very comfortable in her favourite chair, I explained the benefits of the pressure cushion and we agreed that she would sit in another chair with the pressure cushion in situ for a least part of the day and that we would discuss how she got on next time I visited. Before leaving Roses I documented my assessments, nursing interventions, evaluation and actions in her care plan. The second stage of Driscolls entitled now what will look at the chain of events which has led me to reflect on when it is appropriate to delegate care. Delegation involves entrusting and transferring a task or responsibility to another person who is able to accept responsibility for the task, typically one who is less senior than oneself (Sullivan and Decker 2005, Oxford dictionary 2011). However Wheeler (2004) argues that delegation and abdication amount to the same thing. On the other hand MacKenzie (1998) states that abdication is giving up either by abandonment or resignation and says that whilst delegation can offer potential benefits to both individuals and organisations, many nurses practice abdication which can be attributable to the current economic climate of underpaid and overstretched employees. Whilst I did appreciate that Dianne thought I was capable to deliver appropriate care to Rose I also suspected that she thought it she would have an easier day if she asked me to carry out the more routine and mundane tasks. The NMC standards of proficiency (2004) state whilst nurses should delegate care to others they should also accept responsibility and accountability for such delegation. As a registered nurse under the NMC Code of Conduct (2008) nurses have a duty of care to ensure that patients receive care in a safe and skilled manner. Dianne was not aware if I was competent or not to carry out compression bandaging as she had neither previously worked with me or questioned me about my clinical skills. In line with the NMC Code of Conduct (2008) I understand that I must work within the scope of my professional competence and it is for this reason I refused to apply the compression layer. It is important for organisations and individuations to delegate in order for them to develop and function resourcefully and successfully (Ellis and Hartley 2004). Effective Delegation requires skills in planning, analysis and self-confidence. The tasks to be delegated should be assessed, planned, communicated, implemented, monitored and evaluated (Royal College of Nursing 2006). In the UK, the rate of change is accelerating and the delivery of services are regularly restructured in an attempt to provide the most effective and efficient care to patients (Shepherd 2008). This environment has lead to the evolvement of work from junior doctors to nursing staff such as giving intravenous therapy and with the evolvement of nursing practitioners many agree that the role of the nurse is increasingly difficult to define as the boundaries are constantly changing (Shephard 2008, Spilbury and Meyer 2005, McKenna et al 2006). A study conducted by Ulster University condones that there is much ambiguity amongst the nursing role. It concluded that although nurses are happy with role extensions they have less patient contact as they would like. Some nurses like the role extension of technical jobs, however others see it at the menial tasks Doctors do not want to do (Allen 2002). However this was only a small survey of 26 nurses and therefore may not be a true representation of all RGNs (McKenna et al 2006). It can be assumed therefore that demands on nursing care at times are greater than RGNs can cope with, and therefore increasing expected to to delegate some tasks routinely, traditionally carried out by RGNs, such as personal care (Curtis and Nicholl 2004). Effective delegation can give RGNs more time for other activities which enables them to focus on doing fewer tasks well rather than many tasks poorly and offer HCAs the opportunity to become competent and improved confidence (Kourdi 1999). Shepherd (2008) articulates that it is important for these tasks to be defined and when devolved it should not be at the detriment to the patient. As a result health care assistant (HCA) roles have increased in both numbers and cope of activity undertaken and it is therefore important that all health care staff understand their roles and accountability in the delegation process. Health care staff need to work together in order for patients to receive safe and effective care from the most appropriate personnel (Pearcey 2007). However some nurses find it difficult to relinquish any part of their role and find it difficult to delegate (Wheeler 2004) Zimmerman (1996) suggests this might be because some nurses were trained before delegation skills were required. However Nicholl and Curtis (2004) state that delegation is not an art and but a nursing skill which can be learned and is becoming increasing important in changing times. Delegation also enables health care professionals to train in new skills and broaden their skill range. However Wheeler argues that some could abuse their power of delegation for example to provide themselves with extra breaks while their subordinates may have to forfeit theirs to complete additional tasks. Or one nurse could favour a subordinate resulting in some always receiving more appealing tasks than others. Delegation is a complex process and to successfully delegate consideration should be given to both existing workload and skill mix of staff should be known. Delegation of too many tasks may result in loss of control, but failing to delegate may lead to one member of staff being overwhelmed, overworked and can lead to incompletion of duties and de-motivated and un-cooperative team. Most HCAs give personal care due to the fact they are usually more available than RGNS. Many studies have indicated that RGNS favour the employment of HCAs (McKenna and Hansson 2002). However the MIDRIS (2001) study suggests that care provided by HCAS is task based and fragmented. There are many pros and cons for delegating tasks. Detailed Job Descriptions (JD) may result in staff being reluctant to take on new responsibilities that are not specified on their JD. Others will be reluctant and believe if you want a job done properly do it yourself. This can inhibit delegation leading to nurses being overworked stressed with little job satisfaction (Kourdi 1999). On the other hand Wheeler (2001) suggests effective delegation encourages staff to have a better understanding and be able to influence the way in which work is carried out. She also says that by participating in decision-making it will increase motivation, morale and ultimately job performance enabling the organisation to become more flexible and responsive to change. Effective delegation will enable a business to move forward as new ideas and viewpoints will be encourage and it will better prepare nurses to be able to cope when career opportunities arise (Wheeler 2001). Delegation frees up time to enable a nurse to carry out other duties which cannot be delegated. Although at first the time saved might me minimal once the HCA becomes proficient more time will become available. Fewer tasks are better than many that are inefficient (Kourdi 1999). In order to delegate effectively it important to decide which task to delegate , select the best person to carry out that task, assessing the task in detail and offer clearly the level of authority associated with it, , check the skills and experience of the delegates, follow the task process and assess and discuss the progress (Curtis and Nicholl 2004). Cohen suggests it is right to delegate in order to carry out an organisations needs as long as certain criteria is met such as right task, right circumstance, right person right communication and right supervision. The third stage, of the Driscolls reflection model requires what can be done differently in the future and what actions to be taken. Dianne was right to delegate the more junior tasks in order to ensure the fewer tasks she had were carried out more effectively. However should have verified my competence prior to delegating. If she had communicated with me effectively to assess my competence I would not have felt awkward having to point out that I did not have the skills to carry out compression bandaging and only practice within my capabilities (NMC 2008). In the future in such a situation I would not do anything differently as I believe I have a responsibility for practicing within my own capabilities in line with the NMC Code of Conduct (2008). Had I been a permanent member of staff I would have asked for compression training, however this would have been impractical as I was on placement for only a short period of time. When I qualify this situation I will be aware that I am ultimately responsible for the care of patients even when tasks are delegated to HCAs. I will also ensure that I do not delegate anything that involves critical thinking skills such as nursing assessments, planning and evaluation of patient care and nursing judgement.

The Causes of Racial Tension :: Racism

Today, there is racial tension all around the world. Racial tension means the feeling that exists when people do not trust and be aggressive to each other. In Malaysia, racial tension has deepened recently. The Indian government has released an advisory for its foreign students that studying in Australia which showed that racial tension appeared around the White and Indian (â€Å"MEA issues travel advisory to Indian students in Aus†, 2010). Racial tension between the Han and Uighur communities in Xinjiang, China was enhanced in July 2009. There are several factors that causes racial tension to happen such as religion topic, government policy, prejudice and discrimination. Next, racial tension is also easily caused by prejudice and discrimination. According to Jon (1997), â€Å"prejudice is a general characteristic of human relationships† (p. 232). Jon (19970 found â€Å"prejudice is usually considered the cause of discrimination†. Prejudice is easily being found in someone to the others; especially they are from different races. They may treat the other races irrespectively and violently. First, people will not take it seriously. However, when the cases happen frequently and massively, people won’t take them as specials cases. The races that besieged will tend to feel anxious and strike back in order to protect themselves. Therefore, it tends to create racial tension. For examples, incidents of violence against Indians in Australia were happened frequently in last few months. Later on, an Indian student was killed. These have damaged the relationship between the Indians and Australians and created racial tension. Besides, African- Americans were still discriminated seriously by the Americans even after American Civil War. They had perspective that the African-Americans were slaves like they used to be. They received unequal treatment until the success of African-American Civil Rights Movement. The racial tension was existed during the period. The government policy causes the racial tension as well. The governments launch policies that encourage the development of countries. But if some policies tend to benefit certain races, whether they are majority or minority, will cause the dissatisfaction of other races. In their perspective, all races should be treated equally regardless the number of members. Therefore, they may protest to show their dissatisfaction. If their protest were overwhelmed and the government led by the majority, the racial tension is ensured happen. Racial tension between the Han and Uighur communities in Xinjiang, China is an example. Uighur was the minority in China but the large community in Xinjiang.

Mama Day by Gloria Naylor :: Mama Day Gloria Naylor Literature Essays

Mama Day by Gloria Naylor The comparisons--North vs. South, city vs. country, technology vs. nature--are numerous and have been well documented in 20th century literature. Progress contrasts sharply with rooted cultural beliefs and practices. Personalities and mentalities about life, power and change differ considerably between worlds... worlds that supposed-intellectuals from the West would classify as "modern" and "backwards," respectively. When these two worlds collide, the differences--and the danger--rise significantly. This discrepancy between the old and the new is one of the principal themes of Gloria Naylor's Mama Day. The interplay between George, Ophelia and Mama Day shows the discrepancies between a "modern" style of thinking and one born of spirituality and religious beliefs. Dr. Buzzard serves as a weak bridge between these two modes of thought. In Mama Day, the Westernized characters fail to grasp the power of the Willow Springs world until it is too late. "When I was just out of school I worked with a team of engineers in redesigning a nozzle for a nuclear steam turbine generator... It was an awesome machine... And when it ran... lighting up every home in New York, a feeling radiated through the pit of my stomach as if its nerve endings were connected to each of those ten million light bulbs. That was power. But the winds coming around the corners of that house was God" (251). George's experience in the hurricane is just one example of the contrasts between technology and spirituality. George ardently believes that every problem can be solved with rational thinking, planning and plenty of hard work. His obsession with fixing the bridge after the hurricane further illustrates this point; despite assurances from Mama Day and Dr. Buzzard that the bridge would be built in its own time, George diligently pushes the townsfolk beyond their capacity to work. His behavior surrounding the bridge--not to mention the boat he tries to mend--is bas ed on his desire to save Ophelia from a strange illness. He ignores the advice and guidance of Mama Day and plunges into the crisis through rational means. Ultimately, he loses his own life when saving his beloved wife, though George never understands how or why. Dr. Buzzard had warned him that "A man would have grown enough to know that really believing in himself means that he ain't gotta be afraid to admit there's some things he can't do alone" (292).

Effects of Income Inequality on Quality of Healthcare Essays -- The In

Positive rights are rights that everyone is entitled to including: the right to a public education, access to public roads, and the right to health care. There are no guarantees when it comes to life, but having health insurance makes a huge difference with preventing, diagnosing, and treating diseases. Of course having insurance itself is a great resource to ensure medical care and containing costs, but not all insurance programs are created equal. Insurance programs have caveats, exclusions, varying co-payments, and access to certain doctors and hospitals, which creates an ethical dilemma. Receiving the best care is subjective in most cases, but with money you can buy almost anything, including the best care. Although those living in poverty are given access to healthcare, that does not mean they receive the best or equal care as those who are wealthy. Living in a capitalist society, the richest Americans enjoy larger homes, nicer cars, better education and even health care. Even if we lived in a capitalist society where everyone had access to the same basic healthcare program, the rich would still be able to afford better care. The wealthy are able to pay more in co-payments, prescription costs, and the ability to go outside of the healthcare system in this country to seek help. When you have the disposable resources then the sky is the limit, where the poor have very limited options. They will be confined to their healthcare coverage program and do not have the luxury of seeking additional assistance. â€Å"Poor patients often receive less quality care in the hospital, have more barriers to recovery, and experience higher morbidity and mortality than do patients with higher incomes† (Dracup). The United States is ... ...ndards and practices are more uniform based on circumstance and not based on loopholes, exceptions or lack of insurance. Everyone should be given the same preventive care and be able to receive the same treatment options regardless of location, income, or age. Competition in the marketplace can be good, but there are many complexities with healthcare and many people can slip through the cracks and others can be shortchanged. Works Cited C.

[2] Pollutants can be classified as either pri mary or secondary.Usually, primary pollutants are substances directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories. Secondary pollutants are not emitted directly. Rather, they form in the air when primary pollutants react or interact. An important example of a secondary pollutant is ground level ozone  Ã¢â‚¬â€ one of the many secondary pollutants that make up photochemical smog. Note that some pollutants may be both primary and secondary: that is, they are both emitted directly and formed from other primary pollutants.About 4 percent of deaths in the United States can be attributed to air pollution, according to the Environmental Science Engineering Program at the Harvard School of Public Health. Major primary pollutants produced by human activity include: * Sulfur oxides (SOx) – especially sulfur dioxide, a chemical compound with the formula SO2. SO2 is produced by volcanoes and in various industrial processes. Since coal and petroleum often contain sulfur compounds, their combustion generates sulfur dioxide. Further oxidation of SO2, usually in the presence of a catalyst such as NO2, forms H2SO4, and thus acid rain. 2] This is one of the causes for concern over the environmental impact of the use of these fuels as power sources. * Nitrogen oxides (NOx) – especially nitrogen dioxide are emitted from high temperature combustion. Can be seen as the brown haze dome above or plume downwind of cities. Nitrogen dioxide is the chemical compound with the formula NO2. It is one of the several nitrogen oxides. This reddish-brown toxic gas has a characteristic sharp, biting odor. NO2 is one of the most prominent air pollutants. * Carbon monoxide – is a colourless, odourless, non-irritating but very poisonous gas.It is a product by incomplete combustion of fuel such as natural gas, coal or wood. Vehicular exhaust is a major source of car bon monoxide. * Carbon dioxide (CO2) – a greenhouse gas emitted from combustion but is also a gas vital to living organisms. It is a natural gas in the atmosphere. * Volatile organic compounds – VOCs are an important outdoor air pollutant. In this field they are often divided into the separate categories of methane (CH4) and non-methane (NMVOCs). Methane is an extremely efficient greenhouse gas which contributes to enhanced global warming. Other hydrocarbon VOCs are lso significant greenhouse gases via their role in creating ozone and in prolonging the life of methane in the atmosphere, although the effect varies depending on local air quality. Within the NMVOCs, the aromatic compounds benzene, toluene and xylene are suspected carcinogens and may lead to leukemia through prolonged exposure. 1,3-butadiene is another dangerous compound which is often associated with industrial uses. * Particulate matter – Particulates, alternatively referred to as particulate matt er (PM) or fine particles, are tiny particles of solid or liquid suspended in a gas.In contrast, aerosol refers to particles and the gas together. Sources of particulate matter can be man made or natural. Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray. Human activities, such as the burning of fossil fuels in vehicles, power plants and various industrial processes also generate significant amounts of aerosols. Averaged over the globe, anthropogenic aerosols—those made by human activities—currently account for about 10 percent of the total amount of aerosols in our atmosphere.Increased levels of fine particles in the air are linked to health hazards such as heart disease,[3] altered lung function and lung cancer. * Persistent free radicals connected to airborne fine particles could cause cardiopulmonary disease. [4][5] * Toxic metals, such as lead, cadmium and copper. * Chlorofluoro carbons (CFCs) – harmful to the ozone layer emitted from products currently banned from use. * Ammonia (NH3) – emitted from agricultural processes. Ammonia is a compound with the formula NH3. It is normally encountered as a gas with a characteristic pungent odor.Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to foodstuffs and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceuticals. Although in wide use, ammonia is both caustic and hazardous. * Odors  Ã¢â‚¬â€ such as from garbage, sewage, and industrial processes * Radioactive pollutants – produced by nuclear explosions, war explosives, and natural processes such as the radioactive decay of radon. Secondary pollutants include: Particulate matter formed from gaseous primary pollutants and compounds in photochemical smog. Smog is a kind of air pollution; the word â€Å"smog† is a portmanteau of smoke and fog. Classic smog results from large amounts of coal burning in an area caused by a mixture of smoke and sulfur dioxide. Modern smog does not usually come from coal but from vehicular and industrial emissions that are acted on in the atmosphere by sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical smog. Ground level ozone (O3) formed from NOx and VOCs. Ozone (O3) is a key constituent of the troposphere (it is also an important constituent of certain regions of the stratosphere commonly known as the Ozone layer). Photochemical and chemical reactions involving it drive many of the chemical processes that occur in the atmosphere by day and by night. At abnormally high concentrations brought about by human activities (largely the combustion of fossil fuel), it is a pollutant, and a constituent of smog. Peroxyacetyl nitrate (PAN) – similarly formed from NOx and VOCs. Minor air pollutants include: * A la rge number of minor hazardous air pollutants. Some of these are regulated in USA under the Clean Air Act and in Europe under the Air Framework Directive. * A variety of persistent organic pollutants, which can attach to particulate matter. Persistent organic pollutants (POPs) are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes.Because of this, they have been observed to persist in the environment, to be capable of long-range transport, bioaccumulate in human and animal tissue, biomagnify in food chains, and to have potential significant impacts on human health and the environment. [edit] Sources Main article: AP 42 Compilation of Air Pollutant Emission Factors Dust storm approaching Stratford, Texas Controlled burning of a field outside of Statesboro, Georgia in preparation for spring planting Sources of air pollution refer to the various locations, activities or factors which are responsible for the releasing of pollutants n the atmosphere. These sources can be classified into two major categories which are: Anthropogenic sources (human activity) mostly related to burning different kinds of fuel * â€Å"Stationary Sources† include smoke stacks of power plants, manufacturing facilities (factories) and waste incinerators, as well as furnaces and other types of fuel-burning heating devices * â€Å"Mobile Sources† include motor vehicles, marine vessels, aircraft and the effect of sound etc. * Chemicals, dust and controlled burn practices in agriculture and forestry management.Controlled or prescribed burning is a technique sometimes used in forest management, farming, prairie restoration or greenhouse gas abatement. Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters. Controlled burning stimulates the germination of some desirable forest trees, thus renewing the forest. * Fumes from paint, hair spray, varnish, aerosol spra ys and other solvents * Waste deposition in landfills, which generate methane. Methane is not toxic; however, it is highly flammable and may form explosive mixtures with air.Methane is also an asphyxiant and may displace oxygen in an enclosed space. Asphyxia or suffocation may result if the oxygen concentration is reduced to below 19. 5% by displacement * Military, such as nuclear weapons, toxic gases, germ warfare and rocketry Natural sources * Dust from natural sources, usually large areas of land with little or no vegetation. * Methane, emitted by the digestion of food by animals, for example cattle. * Radon gas from radioactive decay within the Earth's crust. Radon is a colorless, odorless, naturally occurring, radioactive noble gas that is formed from the decay of radium.It is considered to be a health hazard. Radon gas from natural sources can accumulate in buildings, especially in confined areas such as the basement and it is the second most frequent cause of lung cancer, aft er cigarette smoking. * Smoke and carbon monoxide from wildfires. * Volcanic activity, which produce sulfur, chlorine, and ash particulates. [edit] Emission factors Main article: AP 42 Compilation of Air Pollutant Emission Factors Air pollutant emission factors are representative values that attempt to relate the quantity of a pollutant released to the ambient air with an activity associated with the release of that pollutant.These factors are usually expressed as the weight of pollutant divided by a unit weight, volume, distance, or duration of the activity emitting the pollutant (e. g. , kilograms of particulate emitted per megagram of coal burned). Such factors facilitate estimation of emissions from various sources of air pollution. In most cases, these factors are simply averages of all available data of acceptable quality, and are generally assumed to be representative of long-term averages. The United States Environmental Protection Agency has published a compilation of air p ollutant emission factors for a multitude of industrial sources. 6] The United Kingdom, Australia, Canada and many other countries have published similar compilations, as well as the European Environment Agency. [7][8][9][10][11] [edit] Indoor air quality (IAQ) Main article: Indoor air quality A lack of ventilation indoors concentrates air pollution where people often spend the majority of their time. Radon (Rn) gas, a carcinogen, is exuded from the Earth in certain locations and trapped inside houses. Building materials including carpeting and plywood emit formaldehyde (H2CO) gas. Paint and solvents give off volatile organic compounds (VOCs) as they dry.Lead paint can degenerate into dust and be inhaled. Intentional air pollution is introduced with the use of air fresheners, incense, and other scented items. Controlled wood fires in stoves and fireplaces can add significant amounts of smoke particulates into the air, inside and out. [12] Indoor pollution fatalities may be caused by using pesticides and other chemical sprays indoors without proper ventilation. Carbon monoxide (CO) poisoning and fatalities are often caused by faulty vents and chimneys, or by the burning of charcoal indoors. Chronic carbon monoxide poisoning can result even from poorly adjusted pilot lights.Traps are built into all domestic plumbing to keep sewer gas, hydrogen sulfide, out of interiors. Clothing emits tetrachloroethylene, or other dry cleaning fluids, for days after dry cleaning. Though its use has now been banned in many countries, the extensive use of asbestos in industrial and domestic environments in the past has left a potentially very dangerous material in many localities. Asbestosis is a chronic inflammatory medical condition affecting the tissue of the lungs. It occurs after long-term, heavy exposure to asbestos from asbestos-containing materials in structures.Sufferers have severe dyspnea (shortness of breath) and are at an increased risk regarding several different typ es of lung cancer. As clear explanations are not always stressed in non-technical literature, care should be taken to distinguish between several forms of relevant diseases. According to the World Health Organisation (WHO)[dead link], these may defined as; asbestosis, lung cancer, and mesothelioma (generally a very rare form of cancer, when more widespread it is almost always associated with prolonged exposure to asbestos). Biological sources of air pollution are also found indoors, as gases and airborne particulates.Pets produce dander, people produce dust from minute skin flakes and decomposed hair, dust mites in bedding, carpeting and furniture produce enzymes and micrometre-sized fecal droppings, inhabitants emit methane, mold forms in walls and generates mycotoxins and spores, air conditioning systems can incubate Legionnaires' disease and mold, and houseplants, soil and surrounding gardens can produce pollen, dust, and mold. Indoors, the lack of air circulation allows these ai rborne pollutants to accumulate more than they would otherwise occur in nature. edit] Health effects The World Health Organization states that 2. 4 million people die each year from causes directly attributable to air pollution, with 1. 5 million of these deaths attributable to indoor air pollution. [13] â€Å"Epidemiological studies suggest that more than 500,000 Americans die each year from cardiopulmonary disease linked to breathing fine particle air pollution. . . â€Å"[14] A study by the University of Birmingham has shown a strong correlation between pneumonia related deaths and air pollution from motor vehicles. 15] Worldwide more deaths per year are linked to air pollution than to automobile accidents. [citation needed] Published in 2005 suggests that 310,000 Europeans die from air pollution annually. [citation needed] Causes of deaths include aggravated asthma, emphysema, lung and heart diseases, and respiratory allergies. [citation needed] The US EPA estimates that a pro posed set of changes in diesel engine technology (Tier 2) could result in 12,000 fewer premature mortalities, 15,000 fewer heart attacks, 6,000 fewer emergency room visits by children with asthma, and 8,900 fewer espiratory-related hospital admissions each year in the United States. [citation needed] The worst short term civilian pollution crisis in India was the 1984 Bhopal Disaster. [16] Leaked industrial vapors from the Union Carbide factory, belonging to Union Carbide, Inc. , U. S. A. , killed more than 25,000 people outright and injured anywhere from 150,000 to 600,000. The United Kingdom suffered its worst air pollution event when the December 4 Great Smog of 1952 formed over London. In six days more than 4,000 died, and 8,000 more died within the following months. citation needed] An accidental leak of anthrax spores from a biological warfare laboratory in the former USSR in 1979 near Sverdlovsk is believed to have been the cause of hundreds of civilian deaths. [citation need ed] The worst single incident of air pollution to occur in the United States of America occurred in Donora, Pennsylvania in late October, 1948, when 20 people died and over 7,000 were injured. [17] The health effects caused by air pollutants may include difficulty in breathing, wheezing, coughing and aggravation of existing respiratory and cardiac conditions.These effects can result in increased medication use, increased doctor or emergency room visits, more hospital admissions and premature death. The human health effects of poor air quality are far reaching, but principally affect the body's respiratory system and the cardiovascular system. Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, the individual's health status and genetics. citation needed] A new economic study of the health impacts and associated costs of air pollution in the Los Angeles Basin and San Joaquin Valley of Southern California shows that mo re than 3800 people die prematurely (approximately 14 years earlier than normal) each year because air pollution levels violate federal standards. The number of annual premature deaths is considerably higher than the fatalities related to auto collisions in the same area, which average fewer than 2,000 per year. 18] Diesel exhaust (DE) is a major contributor to combustion derived particulate matter air pollution. In several human experimental studies, using a well validated exposure chamber setup, DE has been linked to acute vascular dysfunction and increased thrombus formation. [19][20] This serves as a plausible mechanistic link between the previously described association between particulate matter air pollution and increased cardiovascular morbidity and mortality. [edit] Effects on cystic fibrosis Main article: Cystic fibrosisA study from around the years of 1999 to 2000, by the University of Washington, showed that patients near and around particulate matter air pollution had a n increased risk of pulmonary exacerbations and decrease in lung function. [21] Patients were examined before the study for amounts of specific pollutants like Pseudomonas aeruginosa or Burkholderia cenocepacia as well as their socioeconomic standing. Participants involved in the study were located in the United States in close proximity to an Environmental Protection Agency. clarification needed] During the time of the study 117 deaths were associated with air pollution. Many patients in the study lived in or near large metropolitan areas in order to be close to medical help. These same patients had higher level of pollutants found in their system because of more emissions in larger cities. As cystic fibrosis patients already suffer from decreased lung function, everyday pollutants such as smoke, emissions from automobiles, tobacco smoke and improper use of indoor heating devices could further compromise lung function. 22] [edit] Effects on COPD Main article: Chronic obstructive pu lmonary disease Chronic obstructive pulmonary disease (COPD) include diseases such as chronic bronchitis, emphysema, and some forms of asthma. [23] A study conducted in 1960-1961 in the wake of the Great Smog of 1952 compared 293 London residents with 477 residents of Gloucester, Peterborough, and Norwich, three towns with low reported death rates from chronic bronchitis. All subjects were male postal truck drivers aged 40 to 59.Compared to the subjects from the outlying towns, the London subjects exhibited more severe respiratory symptoms (including cough, phlegm, and dyspnea), reduced lung function (FEV1 and peak flow rate), and increased sputum production and purulence. The differences were more pronounced for subjects aged 50 to 59. The study controlled for age and smoking habits, so concluded that air pollution was the most likely cause of the observed differences. [24] It is believed that much like cystic fibrosis, by living in a more urban environment serious health hazards b ecome more apparent.Studies have shown that in urban areas patients suffer mucus hypersecretion, lower levels of lung function, and more self diagnosis of chronic bronchitis and emphysema. [25] [edit] Effects on children Cities around the world with high exposure to air pollutants have the possibility of children living within them to develop asthma, pneumonia and other lower respiratory infections as well as a low initial birth rate. Protective measures to ensure the youths' health are being taken in cities such as New Delhi, India where buses now use compressed natural gas to help eliminate the â€Å"pea-soup† smog. 26] Research by the World Health Organization shows there is the greatest concentration of particulate matter particles in countries with low economic world power and high poverty and population rates. Examples of these countries include Egypt, Sudan, Mongolia, and Indonesia. The Clean Air Act was passed in 1970, however in 2002 at least 146 million Americans we re living in areas that did not meet at least one of the â€Å"criteria pollutants† laid out in the 1997 National Ambient Air Quality Standards. [27] Those pollutants included: ozone, particulate matter, sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead.Because children are outdoors more and have higher minute ventilation they are more susceptible to the dangers of air pollution. [edit] Health effects in relatively â€Å"clean† areas Even in areas with relatively low levels of air pollution, public health effects can be substantial and costly. This is because effects can occur at very low levels and a large number of people can potentially breathe in such pollutants. A 2005 scientific study for the British Columbia Lung Association showed that a 1% improvement in ambient PM2. 5 and ozone concentrations will produce a $29 million in annual savings in the region in 2010. 28] This finding is based on health valuation of lethal (mortality) and sub-lethal (morbidi ty) effects. [edit] Reduction efforts There are various air pollution control technologies and land use planning strategies available to reduce air pollution. At its most basic level land use planning is likely to involve zoning and transport infrastructure planning. In most developed countries, land use planning is an important part of social policy, ensuring that land is used efficiently for the benefit of the wider economy and population as well as to protect the environment.Efforts to reduce pollution from mobile sources includes primary regulation (many developing countries have permissive regulations),[citation needed] expanding regulation to new sources (such as cruise and transport ships, farm equipment, and small gas-powered equipment such as lawn trimmers, chainsaws, and snowmobiles), increased fuel efficiency (such as through the use of hybrid vehicles), conversion to cleaner fuels (such as bioethanol, biodiesel, or conversion to electric vehicles). [edit] Control devices The following items are commonly used as pollution control devices by industry or transportation devices. They can either destroy contaminants or remove them from an exhaust stream before it is emitted into the atmosphere. * Particulate control * Mechanical collectors (dust cyclones, multicyclones) * Electrostatic precipitators An electrostatic precipitator (ESP), or electrostatic air cleaner is a particulate collection device that removes particles from a flowing gas (such as air) using the force of an induced electrostatic charge.Electrostatic precipitators are highly efficient filtration devices that minimally impede the flow of gases through the device, and can easily remove fine particulate matter such as dust and smoke from the air stream. * Baghouses Designed to handle heavy dust loads, a dust collector consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system (distinguished from air cleaners which utilize disposable filters to remove the dust). * * Particulate scrubbersWet scrubber is a form of pollution control technology.The term describes a variety of devices that use pollutants from a furnace flue gas or from other gas streams. In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the pollutants. * Scrubbers * Baffle spray scrubber * Cyclonic spray scrubber * Ejector venturi scrubber * Mechanically aided scrubber * Spray tower * Wet scrubber * NOx control * Low NOx burners Selective catalytic reduction (SCR) * Selective non-catalytic reduction (SNCR) * NOx scrubbers * Exhaust gas recirculation * Catalytic converter (also for VOC control) * VOC abatement * Adsorption systems, such as activated carbon * Flares * Thermal oxidizers * Catalytic oxidizers * Biofilters * Absorption (scrubbing) * Cryogenic condensers * Vapor recovery systems * Acid Ga s/SO2 control * Wet scrubbers * Dry scrubbers * Flue gas desulfurization * Mercury control * Sorbent Injection Technology * Electro-Catalytic Oxidation (ECO) K-Fuel * Dioxin and furan control * Miscellaneous associated equipment * Source capturing systems * Continuous emissions monitoring systems (CEMS) [edit] Legal regulations Smog in Cairo In general, there are two types of air quality standards. The first class of standards (such as the U. S. National Ambient Air Quality Standards) set maximum atmospheric concentrations for specific pollutants. Environmental agencies enact regulations which are intended to result in attainment of these target levels.The second class (such as the North American Air Quality Index) take the form of a scale with various thresholds, which is used to communicate to the public the relative risk of outdoor activity. The scale may or may not distinguish between different pollutants. [edit] Cities Air pollution is usually concentrated in densely populated metropolitan areas, especially in developing countries where environmental regulations are relatively lax or nonexistent. However, even populated areas in developed countries attain unhealthy levels of pollution. [edit] Carbon dioxide emissionsMost Polluted World Cities by PM[29]| Particulate matter, ?g/m?

The principal methodologies are: * Point source dispersion, used for industrial sources. * Line source dispersion, used for airport and roadway air dispersion modeling * Area source dispersion, used for forest fires or duststorms * Photochemical models, used to analyze reactive pollutants that form smogVisualization of a buoyant Gaus sian air pollution dispersion plume as used in many atmospheric dispersion models The point source problem is the best understood, since it involves simpler mathematics and has been studied for a long period of time, dating back to about the year 1900. It uses a Gaussian dispersion model for buoyant pollution plumes to forecast the air pollution isopleths, with consideration given to wind velocity, stack height, emission rate and stability class (a measure of atmospheric turbulence). [31][32] This model has been extensively validated and calibrated with experimental data for all sorts of atmospheric conditions.The roadway air dispersion model was developed starting in the late 1950s and early 1960s in response to requirements of the National Environmental Policy Act and the U. S. Department of Transportation (then known as the Federal Highway Administration) to understand impacts of proposed new highways upon air quality, especially in urban areas. Several research groups were activ e in this model development, among which were: the Environmental Research and Technology (ERT) group in Lexington, Massachusetts, the ESL Inc. roup in Sunnyvale, California and the California Air Resources Board group in Sacramento, California. The research of the ESL group received a boost with a contract award from the United States Environmental Protection Agency to validate a line source model using sulfur hexafluoride as a tracer gas. This program was successful in validating the line source model developed by ESL inc. Some of the earliest uses of the model were in court cases involving highway air pollution, the Arlington, Virginia portion of Interstate 66 and the New Jersey Turnpike widening project through East Brunswick, New Jersey.Area source models were developed in 1971 through 1974 by the ERT and ESL groups, but addressed a smaller fraction of total air pollution emissions, so that their use and need was not as widespread as the line source model, which enjoyed hundreds of different applications as early as the 1970s. Similarly photochemical models were developed primarily in the 1960s and 1970s, but their use was more specialized and for regional needs, such as understanding smog formation in Los Angeles, California.
