Police Subculture Essay

I will be writing my research paper on police subculture and how the affects of police subculture impact the body of the law and how it relates to crime. Police subculture is an array of standard procedures and values that rule law enforcers activates in relation to their contractual responsibilities. Police officers were ranked the fifth most stressful job in the world. Since police work is very stressful, police officers have to deal with many hostile individuals in the public and therefore they need to defined styles to handle these unique scenarios. What I will be talking about in my paper is since police subculture is so different such as their values, and beliefs police share which sets them apart from other members of society. Overall I will be talking about the beliefs of police subculture psychological cause of police subculture, changing police subculture and how police subculture affects our society. Police officers are people the society normally looks up to as epitomes of discipline and protectors of law and order; however police behavior in recent years has been anything but flawless with that being said there is a rise in the resentment and distrust in the public. The public no longer trusts or respects police officers imposing all sorts of changes against them. Police behavior is indeed hateful in some cases especially where minorities or women are concerned. When we dig deeper into the anthropological and psychological cause of this kind of behavior, we notice that police are influenced by a flawed subculture that profound affects the attitude and behavior of most police officers. With that being said this subculture teaches them certain values and beliefs and on the other, it turns the entire police community into a cohesive group meaning causing cohesion that is essentially alienated from the general public. According to Adler, Mueller, and Laufer (1994) police subculture is a â€Å"set of norms and values that govern police behavior, brought about by stressful working conditions plus daily interaction with an often hostile public.† Police subculture is responsible for giving offers a unique working attitude and mindset. Their character and personality is profoundly altered by the vies and values that they learn from existing in this subculture. The one most important thing we notice about this subculture is the idea of insiders and outsiders that lies at the core of all its values. Police officers are constantly reminded of their role as protectors of peace and order which turns them against the general public as they view everyone outside the police department as a potential criminal or suspect. Police subculture is also essentially characterized by violence as researched indicates that, â€Å"Many officers are exposed to a subculture of violence in which they encounter death almost daily. The average citizen generally does not witness in a lifetime the amount of death and violence a police officer experiences in one month.† (violanti,1995) Dr. James Fyfe, a very well known figure in the world of law education and law enforcement indentified some key issues regarding police sudbulture during a police conference in April 1992. He believed that â€Å" characteristics of the police subculture may be responsible for some of the apparent increase in the frequency of police compkaints. He stated that many police officers feel they are soldiers in the war on crime. Fyfe said that this is a war they cannot win, and the realization of this leads to frustration and anger. â€Å"(Eric Jackso,1992) Police officers are severely affected by the values that this subculture promotes and endorses. For instance, police officers are usually alienated from the general society which puts them at a greater risk of being vulnerable to police subculture. This is because they are regularly reminded of the insider/outsider principle meaning giving rise to certain degree of separation from the public. This separation starts expanding with the passage of time until police officers cannot longer relate to the common society this results in deeper association with police subculture, which ultimately shapes their perspective on others. Another reason they cannot relate to the public is because of the accusations that are imposed against them. The public usually treats then with disgust and disrespect, holding them responsible for corruption and plagues police departments and for  general lawlessness in the society. Fr this reason, police officers seeks validation from other police personnel, wh ich makes the inner subculture more effective and powerful. (Christopher Cooper,2000) Violanti(1995) explains: â€Å" The roots of frustration emanate from the central irony of American policing: Society charges police officers with the task of regulation a public that does not want to be regulated. For individual officers, the resulting frustration is exacerbated by a largely unsympathetic press, a lack of community support, and a criminal justice system that values equity over expediency. A sense of societal isolation often ensues, compelling officers to together in a defensive stance.† While this occupational subculture should have been a source of inspiration, it is actually despised by many including some police officers themselves alter they realize how it damaged their vision and personality. Most police officers are racial biased as recent incidents of police brutality indicate. This is because of women and minorities are seen as weaker groups and when they refused to obey police commands, police officers see it as a direct attack on their authority. This attitude has given rise to some serious cause of police brutality against citizens and one such case was that of Thomas Jones of Philadelphia. Commenting on this case, a former U.S Marine and police officer Christopher Cooper (2000) linked these kind of cases to police subculture saying â€Å"Sadly, in our early tenure as cops, we instructed on the â€Å"code† of the police subculture. These are norms that are almost always perverse. Two such norms were operable in the Jones mob attack. The first was if a citizen runs from one of us, we are to beat him severely. Another is that if a citizen physically hurts one of use, we are to hurt that citizen even more before we bring him to the station. And if that citizen has killed a cop, he shouldn’t make it to the station alive.† The marcho-ism that characterizes police culture is also responsible for cases of domestic violence where police officers were charged for hitting their wives and using force to extract obedience. This is indeed a highly disturbing situation, ehich is posing serious threat that happiness of households where one spouse is in the police department. It has been noticed  that when many police officers are domestic abusers even though they may not define their behavior in these terms. Apart from women and minorities, gay men also face serious prejudice especially if they join the police force. Kirschman(1997) writes: As with women, gay men are presumed to lack such manlu attributes as courage, bravery, and loyalty. And like women, when they demonstrate courage and competence, they threaten the notion that only â€Å"manly† men can do police work.

Benefits of Recycling

Recycling has been around for generations, sometimes in different forms, but still around. Earlier generations preserved food items, a unique form of reducing, or recycling (Blashfield and Black). Most people see recycling as throwing paper, plastic, glass, and other items into a blue bag then throwing it on the street for a local company to dispose of; however, others reduce and reuse items to recycle and make items last longer. Recycling has been proven to make a difference in many aspects of materials and energy. According to Nicky Scott, â€Å"The energy saved from recycling one glass bottle will operate a 100-watt light bulb for four hours.†Recycling doesn’t have to be complicated and tedious; it can be easy and very beneficial. As society has grown and the impact of the economy has set in, recycling has become more popular. Many people are seeing the gracious financial, economical, and useful benefits of recycling and its components. Not only are individuals recyc ling, but businesses are too. â€Å"Greening the office will therefore have significant benefits environmentally and financially†¦as many other businesses have experienced† (Clift and Cuthbert 1). Businesses are realizing, as well as individuals, the positive effects of recycling.The benefits of recycling are endless. Virtually anyone can accomplish the task and make a positive change while doing it. With so many items that can be reused or recycled, every person should recycle. According to Nicky Scott â€Å"thirty percent of America now recycles. † Everyone in America should recycle because it helps the environment, benefits society as a whole, and is a cost effective choice. Recycling efforts have been proven to help the environment we live in. Reducing, reusing, and recycling truly help the environment and essentially preserve it.Simple items such as composting help the environment. â€Å"Recycling and composting diverted nearly 70 million tons of material aw ay from landfills†¦Ã¢â‚¬  (National Recycling Coalition). Another major component to the environment that benefits from recycling, or its sub-parts reducing and reusing, are the trees in the environment. Essentially, the more paper products people use, the more trees are needed to supply this habit. Supply and demand play a key role in waster and recycling. If one ton of paper is recycled, twelve trees can be saved.Destruction of forests occurs whenmore paper is needed and trees are cut down, therefore, using less paper reduces this destruction. (Nicks J). The global environment also is positively effected by recycling, or reducing and reusing. Carbon emissions are put out everyday by coal mines, cars, houses, and other buildings. By reducing, a part of recycling, the usage of heat, or energy, can substantially help the environment. â€Å"Recycling benefits the air and water by creating a net reduction in ten major categories of air pollutant† (National Recycling Coalit ion). Many pollutants can be eliminated or diminished if everyone simply recycles or reduces.Many people drink items out of an aluminum can. Aluminum is one of the easiest items to recycle, and it also takes 95 percent less energy to recycle aluminum than it is to produce it (National Recycling Coalition). This reduces the negative effect on the environment greatly. Main energy sources such as coal, methane, and oil will not last forever, maybe hundreds of years, but not forever. Recycling helps preserve sources of energy and other products for future generations and people (Bainbridge). The benefits of recycling on the environment are endless.Simply math calculates that the benefits outweigh the negatives. For future and current generations to recycle is a must, the benefits prove that the environment is a major beneficiary of the efforts to recycle. After all, facts are facts, and recycling has been proven a fact to benefits the environment we all live in. Opposing viewpoints and other sources claim that by not recycling, the environment benefits more than if someone does recycle. Although there are many benefits to recycling, there also are some negative aspects, as with any situation.Opposing viewpoint states, â€Å"Curbside recycling is substantially more costly and uses far more resources†¦This means more iron ore and coal mining, more steel and rubber manufacturing, more petroleum extracted and refined for fuel†¦Ã¢â‚¬  (Opposing Viewpoints 81). This negative effect to the environment is focused on the emissions put out and material used, not the natural environment. Recycling, in some cities although, can be somewhat costly and unorganized. Some people also claim that recycling can be harmful to the natural environment.Recycling sites and places at landfills for recycling can become dirty and unhygienic if managed improperly. The chemicals the recycled material puts of can be harmful if not taken care of precisely. The rainwater also can mix with the material making an especially uncleanly environment, if not organized effectively (Nicks J). If recycling is not managed or organized properly, as with any program or organization, negative effects will occur. Minor oppositions and negatives are associated with recycling, but with anything in life, there are always a few resisting aspects.The environment benefits greatly from recycling by reducing emissions, saving trees and destruction, and preserving wildlife that lives in the environment. Most recycling plants are managed by professionals and attain the highest level of organization; this diminishes many hazards that are caused by mismanaged material. Recycling and composting materials has been proven to benefit and nourishes the environment, not create hazards and risks (Kalenberg). Also, recycling programs cost less to run than landfills or other â€Å"dumping† organizations.â€Å"Well-run recycling programs cost less to operate than waste collection, landfill ing, and incineration† (National Recycling Coalition). These costs also indicate that fewer emissions are put out because many recycling centers are located where the everyday traveler is going, reducing the amount of time a car is running and creating emissions. Recycling also cuts down the need for more energy to be created, reducing emissions in the air and helping the environment. â€Å"Recycling used materials reduces energy requirements in many manufacturing processes such as refining and mining† (Nicks J).By cutting down the destruction and emissions mines, plants, and factories cause, the environment is enhanced not hindered. Another reason why recycling is beneficial and not a hindrance to the environment is pollution. Everyday, in any situation, aluminum cans, plastic containers, and paper products are thrown, not into a garbage can, but out into the environment. People who litter cause many damaging effects to the environment. With recycling, this problem is diminished; there is no garbage lying around and the environment prospers.Recycling is an enormous and outweighed benefit to the environment, not a restraint like Opposing Viewpoints and others claim it to be. Next, recycling is a must because it benefits society in many positive ways. Recycling has become more popular every year because of social and convenience benefits. More people of society are realizing the benefits of recycling. â€Å"The recycling business continues to expand at a faster rate as more and more people are emphasizing the need for eco-friendly surroundings† (Bainbridge). Another benefit to society is the â€Å"lead by example† teamwork aspect.Many people lead byexample and come together for a certain cause. In many cities and towns across the United State, this cause is recycling. People come together, which is a great social benefit. â€Å"Any place you go—school, church, club, business—can become a place where you can get recyclin g activities started and get other people caring about the Earth† (Blashfield and Black 117). Recycling has been proven to bring members of a community together to support a cause, on of the most marked benefits of recycling. Many large cities also have gotten into the realm of recycling, realizing the benefits, but also leading by example.â€Å"New York City leaders realized that a redesigned, efficient recycling system could actually save the city $20 million and they have now signed a 20-year recycling contract† (National Recycling Coalition). Recycling also is very easy to accomplish and virtually anyone can do it. Simply digging a hole and putting many garbage items in it, then covering it up with dirt provides an easy and beneficial compost site (Kalenberg). Recycling is so easy that many children can get involved. Children love to help; recycling also can be a game for children, putting certain items where they go.â€Å"Children really like the idea of recycling (and composting)†¦Ã¢â‚¬  (Scott 35). Blue bins and bags also make recycling very easy. Most people can recognize a blue bag and put recyclable materials (represented by three arrows) into the bag, an idea that is simple and easy. Three key â€Å"R† words also make recycling simple. Reduce, reuse, and recycle combine to create the perfect and simple reminder for recycling. Many household and common products can be recycled in some way. Taking wire hangers to a second hand store or giving them to a steel center is a simple recycling fix (Scott 39).Recycling has been proven to benefit different because it is very easy and provides many widespread social benefits. Opposing Viewpoints, however, claims that recycling is not beneficial to society in any aspect. Some sources say that a recycling program can be unorganized and confusing. Some social negatives towards recycling are also presented. â€Å"Despite the many thousands of curbside recycling programs†¦packaging w aste still account for between 35 and 40 percent of the household waste†¦Americans don’t care enough about recycling, it seems†¦Ã¢â‚¬  (Opposing Viewpoints 42).Socially Americans will not become environmentally conscious until all of our energy and consumable resources are used up, Opposing Viewpoints also claims. Some people find recycling confusing by sorting out certain materials, deciding what to recycle, and how to go about recycling. Opposing viewpoints adds, â€Å"Mandatory recycling programs aren’t good for posterity. They offer mainly short-term benefits to a few groups†¦Recycling may be the most wasteful activity in modern America†¦Ã¢â‚¬  Skepticism is only represented when little evidence is to prove against recycling.Other groups believe that certain types of recycling can also be complicated and tedious. â€Å"There are different kinds of plastic and one has to sort them systematically† (Nicks J). Different materials call for different types of action when recycling, considered a negative view to some. Very little penalties contribute to the effects of recycling on society as a whole. Minimal negative benefits are present to society; however, the positive benefits of recycling to a society outweigh the minimal negatives. â€Å"It seems† does not contemplate a fact or something solid when arguing a point, the first mistake on the Opposing Viewpoints side.Also Nicky Scott states, â€Å"360 million plastic bottles were recycled in 2002. † This shows how many people are taking advantage or recycling because it is very easy. The number shows that each day over 1 million bottles are recycled! Socially, it is important to take care of future generations; daughters, sons, grandchildren, great grandchildren, and so on are the future of America. For these generations to thrive and make the world better, resources are needed, and we need to start preserving them now. Americans and leaders are not wait ing for energy sources to become fully used before recycling.â€Å"Many cities now collect part of the trash for recycling† (Blashfield and Black 15). This shows how society is starting to influence government and cities to do what is right for society. Also, with more people recycling, the packaging waste would be cut down dramatically. Over 80 percent of all the plastic products we use end up in a landfill somewhere (Scott 68). Recycling plastic and reusing plastic cans cut this number dramatically and the need for processing anymore. Also, sorting through recycled material is very easy. Labels on the products (usually a three arrow diagram) explain how to recycle the item.Most directions in recycling are simple and easy. When in drought, put an item with your already recycled material. â€Å"Remember the three Rs of 3RC. Reduce the waste you make. Reuse those items your can. Then, recycle everything possible† (Blashfield and Black 29). The claims that have been made against the benefits recycling can provide for society are merely statements, not facts. Recycling has been proven to help society in aspects ranging from convenience to social bonds. Attempts to nullify these benefits lack research and observation.Recycling is also very economically smart because it costs less and provides more jobs. A conscious financial decision can be to recycle. From a multi-million dollar corporation, to a family in a small town, recycling has been proven to be financially beneficial. Companies are very smart and often set a trend for many Americans. â€Å"Thousands of U. S. companies have saved millions of dollars through their voluntary recycling programs. They wouldn't recycle if it didn't make economic sense† (National Recycling Coalition). Reusing items, reducing consumption of energy, and recycling old products save money, plain and simple.Each time a product can be cut back or reused, is one less time more money has to be spent. Recycling also p ositively effects society by creating more jobs. Research and development can also benefit from recycling by creating fresh and new ideas. â€Å"It [recycling] stimulates the development of eco-friendly technologies†¦Ã¢â‚¬  (Bainbridge). Private sector jobs that are created almost every day to help research and conduct recycling programs along with other recycling-involved jobs create almost 1. 1 million careers in the United States (National Recycling Coalition).This helps stimulate the economy and creates American jobs, which stay in America. Recycling and buying recycled materials also helps to cut down costs. If more items were recycled or made out of recycled material, the cost of a product would be dramatically reduced. â€Å"Roughly 30 cents of every dollar consumers spend on packaged goods goes towards paying for the packaging† (Scott 12). Recycling can be very cost effective to companies and families when accomplished correctly. Some companies and organization s can even increase productivity to become more competitive in a certain market by recycling, reusing, and reducing.Companies in society can benefit from recycling and reducing. Overhead costs, energy costs, water bills, and other expenditures are cut down when recycling and reducing is involved; sales and productivity also are increased due to a good recycling reputation and cost minimization (Clift and Cuthbert 1-2). Also with the current economy recycling is beneficial. Reusing, a part of recycling, can be a very smart financial decision. If materials are reused and recycled, the need to purchase new items decreases. This is very beneficial in an economy that is recovering from a recession, and when budgets are tight.â€Å"Recycling helps families save money, especially in communities with pay-as-you-throw programs† (National Recycling Coalition). Programs all over the United State are designed to make sense financially and economically. A simple task, such as using less p aper towels for clean-up by using and recycling cloth rags, can be a conscious cost decision also. Opposing Viewpoints, however, claims that recycling is not beneficial to society in any aspect. Some sources say that a recycling program can be costly and not a financially sound decision for society.Opposing Viewpoints states that in Ann Arbor, MI the cost of a recycling program is around 1,014,000 dollars, and with other costs associated the program costs over 400,000 dollars more than a typical garbage program (Opposing Viewpoints 103). Others also claim that certain types of recycling are costly and not economically smart for a program. â€Å"Paper recycling can be a bit costly, as additional industrial processes such as bleaching, are required to make the paper reusable† (Nicks J). Recycling programs have also been accused of being expensive to maintain and enforce.Opposing viewpoints also claims that curbside recycling is 35 to 55 percent more than disposing of an item. T hey also state, â€Å"Using less of one resource usually means using more of another† (Opposing Viewpoints 81). This statement refers to recycling and the benefits of it. Some sources agree that recycling costs more than a generalized landfill, or garbage program. Others claim some of the items and products that are made of recycled products can be costly because some items cannot be used, even after being recycled. â€Å"There is no guarantee that the new recycled product obtained will be of good quality.This is because recycling involves manufacturing products from used materials† (Nicks J). There is a slight risk that is associated with recycling and the products that come as a result of a recycling program. Overall, little evidence is presented on why recycling is not beneficial to the American society. Although mismanaged recycling programs can be costly, most recycling programs cost less than a traditional garbage system. Using words like â€Å"usually† of ten result in a lack of research and representation, concluding why the opponent used these words.Opposing Viewpoint’s information for society was based on one city, Ann Arbor. This cannot speak for the entire nation; it is one cities bias towards recycling. The facts that benefit economically outweigh the opinions of the opponents. Society does benefit from recycling with regards to economic interests. Compared to the landfill industries, recycling is definitely more beneficial. â€Å"Recycling creates four jobs for every one job created in the waste management and disposal industries† (National Recycling Coalition). Creating jobs can be one of the most important blessings to society economically and socially.According to Ross Bainbridge recycling is beneficial to society because it offers financial and social benefits such as cutting costs and increasing production for some businesses. Although, the opponent claims that recycling costs more than other programs, there is no support or statistics to support these findings. On the other hand research has been done to prove otherwise. â€Å"Well-run recycling programs cost less to operate than waste collection, landfilling, and incineration† (National Recycling Coalition). Many curbside programs cost no extra money at all.The recycled items are placed beside garbage and are disposed of at the same time. Despite the faulty claims by opponents of recycling, organized recycling programs have been proven to be cost effective and economically comprehensive. Recycling programs are beneficial and continue to be. The benefits of recycling are endless. Many benefits offer no reason not to recycle. Every person should recycle because it helps the environment, is economically sound, and benefits society. With so many items that can be reused or recycled, every person should recycle.Recycling also is very simple and easy to do. Even many children and teens are getting involved with the revolutionary pro cess. According to Nicky Scott thirty percent of America now recycles. An increase that has happened in just a few years. Everyone should to recycle and help this figure grow until every American is recycling and witnessing the benefits of it. Everyone also should recycle because it benefits the natural environment, provides many positive effects on society as a whole, and is very cost effective. Benefits Of Recycling The highly material intensive nature of the modern industry has led to huge resource consumption and compilation of large amount of industrial and municipal waste leading to depletion of natural system, erosion of earth’s resource base, global warming, rise of sea level, deterioration of environment, and increasing extinction rate of animal life, causing severe impairment to earth’s ability to support the human civilization in its current framework.The dangers presented by the unchecked growth and resource consumption became manifest to the world in 1985 after the discovery of the ozone hole over Antarctica that informed the global community of the urgency of problem. As a consequence and in the response to the challenge presented to humanity’s future by its own march towards development, leaders of world met in June, 1992 in Rio De-Janeiro in the first earth summit where against the current pattern of development, sustainable development was identified as the re quired path for the world to follow.One of the important aspects of sustainable development has been recycling of products and waste. Benefits of recycling for society Recycling as a process holds important place in the course of sustainable development for any society. As an activity, its relevance extends beyond a goodwill action to one that holds crucial environmental, economic and social significance for the society and the country (Pellow, Schnaiberg, Winberg, 2000).Recycling helps to constitutes a perfect model of social and urban development where resource consumption is optimized and needs for new material contained while production is maintained at the same levels, thereby driving up the profits and quality of life in the urban communities. The urban community in the post industrial phase has been swamped by the problem of municipal waste and garbage, which has taken menacing proportion, both from the point of view of making valuable urban landscape as redundant as well as causing significant environment damage.In the initial phase of recycling that started in 1960s, it was an avenue for employment for the marginalized section and profit making opportunity to many private entrepreneurs. The hauling, collection and dumping of garbage was a big problem for municipalities of many cities and was considered an unnecessary drain on their already constrained financial resources, causing deterioration in quality of city life.As the private entrepreneurs saw opportunity in the business of waste management and trash disposal they developed professional expertise in gaining maximum value out of the waste that was an important step in emergence of recycling (Pellow, Schnaiberg, Winberg, 2000). In the forthcoming years it was realized that recycling was also an important tool with tremendous potential to reduce the human pressure on environment, land and natural resources that were strained due to continued cycles of consumptions and waste production over years (Y oung, 1995).It was a vital break from its image of a ‘just a do good activity’ to one that was fundamental to driving economy and society on a new path. Environmental benefits of recycling Various studies in industry and academic circles have reported that recycling is among the most effective techniques to reduce the threat of greenhouse gases, contain global warming and alleviate the dangers of extreme climatic change that the world is facing (Benefits of Recycling, 2005).These studies point out that as reusable material is made available through recycling prevents the environmental damage that the fresh extraction of these materials would have caused. Further it also saves the amount of energy, water and other raw materials that are considerably higher in manufacturing of virgin products than recycling. The Department of Environment and Conservation conducted a comprehensive study on the feasibility and benefits of recycling of some of most used substances which are (Benefits of Recycling, 2005) (a)Paper/Cardboard; (b) Liquid paperboard; (c) Glass;(d) Aluminum, (e) Steel;(f) PlasticIn addition, research has also shown the usefulness of recycling for solid and municipal waste and water in optimizing the resource use without compromising with the requirements of the society. The major environmental benefits of recycling are in the area of 1. Green house gases. Recycling helps to contain the extraction of resources and limit the release the green-house gases thereby helping to reduce global warming. The gases whose emission is commonly controlled and mitigated by recycling processes are (a). Carbon Dioxide; (b) Methane; (c) Nitrous Oxide and (d) Oxides of sulphurMost of the households in world use considerable amount of products that are easily recyclable, such as paper and cardboard. Their recycling prevents thermo mechanical pumping of wood, a process that releases gases like carbon-di-oxide and methane in the atmosphere leading to greenhouse ga ses concentration. Similarly useful results come from recycling of glass, which is third in weight proportion among all recyclable materials. Manufacturing of fresh glass requires treatment with soda wash and lime, that contribute significantly to the concentration of greenhouse gases.Recycling of aluminum also saves cutting down in emission of many environmentally harmful gases and products that cause global warming. 2. Energy savings: Energy consumption has been recognized as environment conservation, as it’s the disproportionately greater flow of energy through natural systems that is causing problems of greenhouse gases and global warming. Recycling helps to greatly improve energy efficiency by reducing the energy demands otherwise required for manufacturing and processing of virgin materials.As most of the heat required for creation of products such as paper, cardboards, and packaging materials is obtained through burning bio-mass, recycling become significant in both th e protection of the bio-mass, increasing earth’s capacity to contain carbon dioxide as well helping to reduce the production of carbon-dioxide and methane. Water savings: Decreasing fresh water resources have become a cause of global concern. The scarcity of drinking is already prominent many Asian and African countries, and its estimated that it would effect even the developed European, American and Pacific countries in the eventual run.Among the sectors consuming fresh water, industrial processes emerge as the primary users as well as pollutants of the rivers, lakes and other fresh water resources. Recycling of substances, especially plastic materials and products, results in saving of enormous quantities of fresh water that is otherwise wasted in first batch production. Industrial benefits Recently attempts have been directed towards improvement in recycling process through introduction of recycling parks and recycling industrial zones, that are based on generic concepts o f reuse and recycle etched in the industrial ecology framework (Pellow, Schnaiberg, Winberg, 2000).A recycling industrial park or zone contains a host of facilities and technical features such as solar power inputs, waste reduction technologies, refinery, greenhouse gases monitoring plant, and central heating plan. All of these facilities are integrated in a system design that helps them to share and transfer energy and waste, thereby minimizing the requirement and production of them. Further, the wastes produced in one process is used as input material for another processes (ibid).Paper industry and aluminum industry have been among the foremost users of recyclable products, introducing structural changes in their operation and functional modes to help them use the huge amount of recyclable material that was available through just one decade of emphasis on recycling (Young, 1995). The increasing prices of aluminum raw materials and wood also made recycling a very prospective and co st cutting option for these industries. As a result, in New York alone, whereas the annual cost of disposing newspaper was $ 6 million every year until 1992, recycling made it a profitable business generating over $ 30 million from 1994.Business and industries are also more focused on recycling after a general social consciousness towards environment that has increased the demand of recyclable products. Hazardous and municipal waste management United states produces enormous volumes of solid waste, a great part of which is hazardous and presents serious risks to health of people if left unattended. The problem of managing hazardous waste became a challenge for government and civic administration in 1970s as it required landfills and incineration at wide scale, thereby creating the dangers of severe land pollution and air pollution (Needleman, 1994).In response the EPA instituted policies that started to govern unchecked disposal of hazardous wastes in landfills and encouraged compan ies towards using a significant part of the recyclable material, causing a significant reduction in amount of waste being disposed (Needleman, 1994). It was immediately recognized in the civic administrative circles that by far, recycling was the cheapest and most convenient method of waste management, as well as promising avenue to boost economic development.Consequently various city administration and states have taken steps towards financing measures, tax assistance and technical help to promote recycling on a wider platform (Young, 1995). Various facts related to benefits of Recycling Various informative facts related to benefits of recycling are (Benefits of Recycling, 2007) 1. One ton of paper made from recyclable material helps to save 17 trees, 7 gallon of water, approximately 460 gallon of oil, 590 pounds of air pollution, 3 cubic yards of landfill space and 4 kilowatt hours of energy.Effectually it results in reduction of air pollution by 74 percent, water pollution by 35 percent and energy consumption by 64 percent. 2. Recycling of aluminum helps to save every year around 19 million barrel of oil. For a comparative analysis, this is equivalent to energy supplied to about 18 million household every year. 3. Recycling one glass bottle saves energy that is sufficient to light a 100 watt bulb for four hours. 4. Recycling one ton of plastic helps to save energy that is equivalent to 1100-1200 gallons of gasoline. 5. Use of recycled aluminum to make cars decreases the comparative air pollution by a margin of 95 %.6. More than 41,000 tress could be saved every day in US alone if all the newspapers published in a day are recycled. 7. Recycled motor oil helps to reduce dependency on the imported oil. 8. Recycling industry helps create a number of jobs, helping in growth of economy in generating income as well as cutting costs. According to the Office of Federal Environmental Executive, Recycling and remanufacturing industries have helped to create more than one million jobs in the economy and their aggregate revenues have been over a staggering $ 100 billion (EPA, 2006).Further, the industry has a rich job profile offering employment to part time and low level workers to top management personnel and scientists. Recycling industry is also instigating discovery and invention of new research and development techniques to utilize greater number of materials as recyclable products, along with keeping the process of recycling cost incentive, so that it is able to compete with the mainstream industrial production processes on the real-time scale of quality, cost and profits.Conclusion As the recycling industry is maturing and creating its own niche, it has become evident that the industry holds enormous potential in restructuring the entire economic, environmental social paradigm. On the one hand the recycling industry helps to save precious and limited natural resources, while bringing down the cost of manufacturing, and on the other it crea tes hundreds of thousand of jobs as a full fledged industry in itself.By reducing the pollution of land, and helping to cud down greenhouse gases, recycling also plays a foremost part in containing the threats of global environment and securing the future of humanity on the path of consistent development and progress.

Case Study Fast Fashion Essay After two decades of fast fashion popularity, retailers and consumers have come to realize one of its biggest issues, its impact on the environment. Can fast fashion and sustainability work together? The affordability of Fast Fashion is one of the main reasons for its high demand. Lack of authenticity or Intellectual Property. Fast Fashion has forced retailers to desire low cost and flexibility in design. Lack of quality in production Rapid production prevents consumers to get an idea of what’s to expect. (Forecasting) Excess of production. Wastes of these products from the retailers and consumer harm the environment. Reveals what is exposed in runways and fashion shows ahead of time. Fast fashion exploits the young consumer by incentivizing impulse behavior. Consumers are getting used to buying more frequent. Due to such rapid turnover, there’s a lack of exclusivity. Step 3 1. Higher quality, lower quantity. Pros Better option for repair: The customer will rather repair a good quality garment than can last than an inexpensive low quality one. Customer satisfaction: Consumers will be happier with a better value product. Long life: Products that are of better quality will definitely last longer so the consumer wont be forced to dispose. For the retailer, there is a great possibility they may attract a variety of new consumers that do appreciate superior quality. As a result of lower quantity, garments will stand out by look fresher and spacious on the sales floor. Cons Retailers may suffer fewer sales. There is a possibility they may lose some of their usual customers. Fewer options, now that there is a lower quantity. Higher quality means it wont be as affordable for the consumer as it used to be. Companies may have to reinvent themselves and state the fact that they are now enhancing the quality of their products. Consumer will be unwilling to compromise on price. Pros Consumer will be satisfied with having a say in the creation of its particular product. This idea will attract and motivate many more consumers. It’s innovative and fun for the consumer. The design will be personalized and the consumer will want to keep. Cons May require more shopping time for the consumer Products may not be as inexpensive now that the retailer will cater to every individuals needs. Consumers of fast fashion may be disappointed that there will now be less variety. Consumers may not adapt to this idea and reject it. 2. No more wasting, get compensated! Recycle and Reuse. The system involves customers bringing all the used items back to the stores and getting compensated with either a discount or a minimal refund. This is to incentive the customer to care more instead of wasting and harming the eco-system. Pros Companies will be take back used garments and send them off to countries in need. Companies will be able to reuse and reproduce them. Customer’s ability to help other in need is facilitated by the companies they have purchased from. Customers get an incentive to bring items back after knowing they also get a discount/store credit/ refund. Case Study Fast Fashion. (2018, Oct 15).

Manage Quailty Customer Service - Identify and evaluate Customer Essay

Manage Quailty Customer Service - Identify and evaluate Customer service - Essay Example As all these prospective customers cannot be get hold by the marketing department at a single place, questionnaires has to be distributed to or featured in all the prospective places, where they will frequent. For example, as the Kingsley Hills as a whole was being developed and promoted by State Tourist authority, the questionnaires along with a pamphlet about the Guest house, can be placed at their various offices and outlets with their permission. It could also be placed in the offices of various travel or tour operators. In addition, when Tourism related fairs are conducted, Ralph and Momo can open up outlets there, and distribute these questionnaires among the visitors. In all these places, they can appoint a person to supply these forms to the customers, requesting them to fill and give in-person or can ask them to post. In addition, Ralph and Momo can open a website for this guest house, and also incorporate a questionnaire in them. Although, all the prospective customers may not respond, the responses of the ones who responded, should be collected and analyzed to assess the customers’ needs and could also help to figure out the target customer base. Customer Service Plan Executive Summary Kingsley Hills Guest House, owned and managed by Ralph and Momo, have opportunities to develop because of the features it is endowed with. The serene and comfortable guest houses with dining and spas can relax and rejuvenate the target customer base of professionals, businesspeople, their families, friends, etc. If these customer segments are treated effectively through various optimal facilities and importantly effective customer service, they will surely enjoy their stay, without any complaints. Even if complaints are raised by the customers, the personnel should handle them aptly. In addition, if the customer service personnel are monitored and motivated, they could provide good output. Introduction For organizations in any sector, customers are the Kings. On ly if the target customer base is found out and enticed through effective marketing strategies, any organization can succeed, or even survive. Marketing strategies will not be successful and importantly it cannot be formulated aptly, without the marketing department conducting market research. Once the market research is done, and the target customer is cornered and importantly their expectations and needs are found out, marketing strategies can be initiated. In service industry, customers will have heightened expectations, and so naturally they will have high grievances as well. So, organizations have to fulfill all those expectations and solve those complaints with the aid of an optimal customer service plan. Customer service plan involves formulating guidelines on the needs and expectations of the customer as defined by the customer. Based on or even using that plan, organizations need to know what their customers want, what they expect, so the organization and in particular the customer service can provide that to them on a consistent basis. (Saleem, 2007). Target market and likely potential guests of Kingsley Hills The target market or the potential guests of Kingsley Hills are professionals, businesspeople, their families, friends, etc., who want to have a relaxed and rejuvenating vacation or picnic in the countryside. As stated in the case, the

Final exam - Essay Example Virginia Woolf was a significant heroic figure in the literary world. She was also a figurehead in the Bloomsbury group as she was very influential. Some of her most famous books include Mrs. Dalloway, to the lighthouse and a room of one’s word. The most memorable quotes from her work entail that any woman with a passion for writing must have her place and money Even though, she suffered from severe mental problems throughout her life her heroic attributes remain unforgotten. She greatly suffered from bipolar disorder that encompasses the most common mental health problem worldwide. She mainly emphasized on equality between men and women in her work. During the literary journey, she was known as one of the most famous writers in the 20th century who utilized modernism. Innovation centers on a literary motion that enables the practitioners to discover better and new ways of relating the experiences of human beings in a time of history that seemed to lack hope. She was a very innovative writer and in most cases she would capture the untamed thoughts of her characters. Pablo Picasso was a modernistic legend who made a great impact in history. The Spanish painter, poet, sculptor and ceramicist among many talents was born in 1881 and died in 1973. Pablo lived in France and was always remarkable and excellent at his work. He created a platform for most modern day painters and playwrights. He was among the most influential, highly talented artist in the 19th and 20th century. Pablo Picasso together with Henri Matisse utilized great modernism in their work. Pablo founded the Cubist movement, invented the sculpture that got constructed and also employed a variety of remarkable styles in his work as an artist. The most notable works he created include the Guernica and Guernica bombing. The Guernica bombing piece of art portrayed the destruction that came about as a result of bombing Guernica. The bombing was done by the Italian and the German air

Different aspects of domestic violence Essay Example | Topics and Well Written Essays - 1750 words

Different aspects of domestic violence - Essay Example It is this definition that has been the basis of evolution for policing policies as applied to domestic violence. The trend in policing today is for the police department to compose of a triage. For example, in many police departments across the United States, when an officer responds to a domestic violence call, he/she may contact the dispatcher, who will call the Crisis Center for Women 24-hour hot line. Then the Crisis Center sends a response van to the scene and will transport the victim and children to the Center's shelter. The Center will also provide transportation to court appearances and provide court advocacy. This on-scene response is available for all situations, 24 hours a day, 7 days a week. After the on-scene response is complete, the case is turned over to the domestic violence unit, which consists of two full-time investigators who handle all incoming cases. Defenders of mandatory arrest and prosecution policies contend that battered women are too helpless and fearful to make appropriate decisions about the arrest or prosecution of their attackers. While this may be true for some women, preliminary evidence shows that the option to decide sometimes provides the perfect avenue for expressing unrealized strength and power. Accordingly, it is premature to judge whether the mandatory rule is actually working. A great deal of the responsibility for preparing for and responding to terrorist events rests with local police departments. Community policing presents an overarching philosophical orientation that agencies can use to better deal with the threat of terrorist events and the fear that they may create. The community policing philosophy can be roughly divided into three interrelated elements: organizational change, problem solving, and external partnerships. Each element applies to the issues of terrorism prevention and response, as well as to fear. Since 9/11, the federal government has greatly increased terrorism prevention and response efforts. However, a large degree of responsibility for dealing with these threats and for alleviating citizen fear rests at the local level. To some degree, the majority of local police departments in the United States have worked to reduce the fear of future terrorist attacks and to prevent and plan for attacks. Law enforcement officials are strategi cally rethinking public security procedures and practices to maximize the potential of their resources. The philosophy of community policing is important for police in preparing for possible terrorist acts and in responding to the fear they may create. Community policing involves broadening the nature and number of police functions compared to traditional policing models. It emphasizes organizational change, active problem solving, and external partnerships to address issues that concern both the police and citizens. In recent years, the philosophy of community policing appears to have been adopted to differing degrees by a large number of law enforcement entities in the United St

Irish Folk Costume Essay Example | Topics and Well Written Essays - 3250 words

Irish Folk Costume - Essay Example The revival of Irish dancing caused viewing of the Irish national dress as a colorful and flashy. However in ancient Ireland people traditionally wore leine (Irish for shirt), trews (Irish for trousers) and long brats (Irish for cloaks) fastened with a brooch. These pieces of clothes (leine and brat) were the basic elements of ancient Irish dress for people in the upper classes. These lasted from the earliest recorded times down to the 16th century. Irish national dresses worn by people back in the eighth century have had great influence on the dresses that Irish dancers wear today. If anyone wants to get an idea of how Irish peasants looked like in the eighth century, one should just have a look at the dresses worn today by Irish dances. The dresses used in their shows are updated replicas of traditional dresses decorated with elaborate Celtic designs from the Book of Kells and emphasized with a Tara Brooch which is pinned to the shawl. The traditional colorful costume of Irish peasants stayed actual up to the beginning of the 20 th century. The Gaelic League was created in 1893. The aim of this organization was to promote Irish nationalism. To reach this aim the League organized Irish dance classes and competitions called Feisanna, which is â€Å"Festival† in Irish. The purpose of these classes and competitions was to make sure that people were dancing the national dance. The organizers believed that if people danced national Irish dances they would not go in for any other dances that weren’t Irish, English dances specifically.

Health care Research Paper Example | Topics and Well Written Essays - 1250 words

Health care - Research Paper Example One of the most industrialized nations in the world, the United States is not safe from this predicament either. The health cover plans that are in place are varied and take care of certain groups of individuals leaving out others. One group that is catered for in the various schemes is the workforce or rather the labor market, and this group has a great impact on the effectiveness of healthcare. This paper will be a discussion on whether the changing labor market in the United States has an impact on universal health care. A universal health care system refers to one specific provider of health care to the whole nation. This is a system that is governed by the same rules and takes care of individuals from all walks of life; an example could be the government taking care of all health care needs of its citizens. However, this is not the case in the United States, various health insurance institutions exist, each of them providing covers for different subgroups of the population (Madrian 138). Health insurance may be provided as a condition of employment, but sometimes it is provided when individuals are not employed or when on a part time job. Despite the fact that all these health insurance providers exist, the most significant health insurance providers are employers. These are followed by the government that provides 16.8 percent of the cover for the non-elderly population. Medicare is the largest government health insurance program, it provides cover for individuals that are above 65 years, as well as those that are below this age but are disabled, therefore eligible for social security insurance (Madrian 139). With the population of the United States composed of individuals that are mainly below 65 years, employees remain the dominant providers of health care coverage programs. With the need for proper health cover, many people in the United States strive to find proper and permanent jobs. This is with regard to the

Henri Lefebvre Essay Example | Topics and Well Written Essays - 1250 words

Henri Lefebvre - Essay Example These critiques of the city were the basis for Lefebvre's investigation of the cultural construction of stereotypical notions of cities, of nature and of regions" (Shields, 2002). Within his writings, Lefebvre brought attention to the tendency of academia to place too much emphasis upon the classification of studies as being psychology, sociology, archaeology or geography among others, that all had as their end goal a study and understanding of space and other human geography issues. In analysing city life, Lefebvre argued 'everydayness' or banality is a soul-destroying feature of modernity and extended Marx's analysis of this concept by discovering new forms of alienation within the city. According to this view, consumption is part of the result of a failure to recognize this alienated state on the part of the modern consumer, which Lefebvre called the 'mystification' of consciousness (Shields, 2002). This early work influenced Walter Benjamin's Marxist analysis of culture as well as reflecting Le Bon's work on crowds and the furtherance of psycho-geography. In discussing space, Lefebvre delineated three key components of the urban lifestyle. These components include the perceived space of everyday social life that was predominantly ignored by professional life, the conceived space of cartographers and planners who work to segregate portions of land out to particular private owners within the capitalistic society, and lived space which exists in the imagination of the fully human individual who keeps it alive through accessibility to the arts and humanities. "This 'third' space not only transcends but has the power to refigure the balance of popular 'perceived space' and the 'conceived space' of arrogant professionals and greedy capitalists" (Shields, 2002). This conceptual space, as opposed to material space, is considered by Lefebvre to be of much greater significance to the shaping of the individual as is shown in the comment: "space as directly lived through its associated images and symbols, and hence the space of 'inhabitants' and 'users'... This is the dominated...space which the imagination seeks to change and appropriate. In terms of organized society, Lefebvre indicated this conscious awareness of these representational spaces as illuminated through art and the humanities was the only way in which Utopia could be reached. Within the French society of the interwar period, Lefebvre pointed to the dystopian malaise of his fellow countrymen as they struggled through periods of famine and industrial transition as well as the later society in which the urban landscape changed the rural nature of his homeland to develop his rhythm analysis. Through this analysis of the 'everyday' life of the city, Lefebvre indicates that the increases in speed seen through our advances in technology have quickened the tempo of the 'everyday', making it harder to keep up with both the changing rhythms of the city as well as the changing dynamics of the individual within that city. This model of modern concrete spaces and their interrelationship with the conceptual interior spaces that have been defined within the modern context have helped human geographers to further

Compare and contrast Gandhi and Plato on the issue of appearance and Essay

Compare and contrast Gandhi and Plato on the issue of appearance and reality - Essay Example pularly known as Mahatma Gandhi, and in India as the Father of the Nation was that ‘great soul’ in human form who was able to mobilize millions of people towards nonviolence through principles of nonviolence and truth; he rose to lead the Congress in 1920, during British Imperialism in India, and successfully brought an end to the British rule in India through his basic yet revolutionary principles and radical politics (Dalton, p.27). Both Plato and Gandhi, considered as highly learned super souls, possessed an ability to mobilize masses through their principles and values. Plato was the first one to differentiate between appearance and reality through his views of the world as a pale reflection of different forms as they appeared to the eye; he philosophized that the world is actually changing constantly, and all impressions, as seen, are mere forms (Gelb, 29). Plato explained his ideology of ‘world of forms,’ and their reality, through parable of prisoners in a cave; he pointed at the ‘reality’ of prisoners’ view that is restricted to their own shadows seen on the walls of the cave from the light behind them. If these prisoners are not exposed to outside world, they will tend to believe that the shadows that are visible are the forms of the world. When they are exposed to the outside world, which is the truth, they will not be able to accept it immediately and will have difficul ty in understanding and adjusting to the light and other objects of truth in the world. Through this explanation, Plato explained the relationship between knowledge and reality that is connected through wisdom. A true philosopher is the one who is in constant search of wisdom that will enable him to identify the goodness, truth, and beauty of life. Quite different in approach was Gandhi’s perception of appearance and reality, in other words conceptualization of metaphysics; were based on the issues that pervaded India for many centuries. Although Gandhi fought

Voter Initiatives Affecting Ell Essay Example for Free

Voter Initiatives Affecting Ell Essay It is no secret that the debate over what is the best course of action to educate our non-native English language students across the country is a highly charged topic that runs from the classroom to Capitol Hill. There have been many shifts in direction and focus of educational programs for English Language Learning (ELL) students during the past century in our nations history. In 1968, with the passage of the Bilingual Education Act (Title VII of the Elementary and Secondary Education Act) legislation was adopted to support programs for educating language-minority students. For the first time, this federal law provided legal guidelines and funding for transitional bilingual education programs. This legislation was further developed in 1974 as a result of the US Supreme Court ruling in Lau V Nichols where a group of Chinese immigrant parents in San Francisco argued that the school district was not adequately providing an equal and effective education because they failed to address their students needs to learn English. As a result of this ruling the mandate to school districts was established to focus funding and attention around a sufficient bilingual education program. Several rulings following this case helped to clarify the need for adequate pedagogy, a sufficient number of qualified teachers to implement the program and a system to measure the effectiveness (Mora,2009). However, the tone of bilingual education began to shift beginning in 1998 when states began to propose anti-bilingual-education ballot initiatives. Three such initiatives were passed in California (1998), Arizona (2000), and Massachusetts (2002) but were rejected in Colorado (2002) and Oregon (2008). (Mora, 2009) All three initiatives in California, Arizona, and Massachusetts were initiated by the same person, Ron Unz, a wealthy chairman of a financial services software company from California. The result of his efforts created Proposition 227 in California, Proposition 203 in Arizona and 603 CMR 14.00 in Massachusetts which all required that English language learners be educated for one year in a sheltered English immersion program. After that time students must then transfer into mainstream English classrooms. The laws only allowed for instruction of students in their non-English native language under limited and restricted conditions through a parental petition and waiver process (Mora, 2009) The real issue at hand concerning these introduction of these laws are much deeper cultural and sociological issues. According to the California Department of Education, changes in school demographic figures indicate that the language minority student population at that time was growing two and a half times faster than the general student enrollment. As an example, nowhere was this change more notable than in California where 1.4 million students were classified as English language learners, with native Spanish-speakers comprising 82 percent of this population (Weisman and Hanson, 2002). Before the implementation of Proposition 227 eliminated the need to provide bilingual education, California was reported to be short 22,000 bilingual teachers. Bilingual teachers on average were paid $5000 more annually than non-bilingual teachers. This law eliminated the need for these resources. To other voters, the concept that children can learn in their native language while also learning English and eventually achieve academically in English contradicted the American tradition of assimilating immigrants into the mainstream society. To many opponents of the bilingual education program that existed prior to these laws, encouraging bilingualism and biculturalism threatened the very definition of the American culture, which, they believed, promoted the values and language of a common group (Weisman and Hanson,2002). ). These proponents of the initiatives believed that new immigrants must abandon their native languages and cultural practices to fully assimilate into U.S. society. They feared that Spanish-speaking immigrants in particular had been clinging to their language and resisting learning English (Mora,2009). It remains to be seen the impact that this legislation has had on the academic outcomes of ELL students. In Arizona, research has suggested that the immersion program has been ineffective with only 11% of students entering the one year program actually obtaining English proficiency within a one year period (English for children, 2013). In California, due to the dramatic changes in the education policy of the state since the passage of Prop 227, it is difficult to measure the impact that Proposition 227 specifically has had on the outcome of these students (American Institutes for Research and WestEd, 2006). One thing is clear, the improvement in the outcomes for ELL students since the adoption of these state initiatives has not been noteworthy. While there has been a slight decrease in the performance gap between ELs and native English speakers, it has remained virtually constant in most subject areas for most grades (American Institutes et al, 2006). Despite the new law, the growing presence of students whose native language is not English indicates that the need for teachers who can understand the language and culture of their students has not waned (Weisman,et al 2002). Educators have reported that since the implementation of the law in their classrooms they have felt frustrations about instructional constraints, concerns about adverse effects on students, fear, intimidation, tension, and a sense of political consciousness(Weisman et al, 2002). In conclusion, the one common denominator resulting from the implementation of the state voter initiatives is that it has created conflict between the law and the instructional tools that educators know to be effective. The initiatives have been more of an expression of cultural ideas and insecurities that have affected the productivity and the role of our education system as it pertains to integrating immigrant Americans. In the future, in order to best navigate the changes in policies and legal mandates concerning the outcomes of ELL students, educators should lean more on research and experience to drive educational programs that will be most effective to this population of students. In this way, our countrys education system can lessen the emotional impact of various cultural groups and political agendas and allow all students to receive the core educational standard set forth in the Equal Education Opportunity Act of 1974, a fair and equitable education for all students regardless of race, ethnicity or language of origin.

Classical Criminology Theory Essay Example for Free

Classical Criminology Theory Essay What is the classical school of criminology and what are the main points of this theory. Cesare Beccaria was a key thinker of this theory and is also considered by some the founder of modern criminology. Classical school of criminology theory placed emphasis on human rationality and free will. Second off this theory unlike the others researched the prevention of crime not the criminals. Also, according to this theory, crime was the result of people choosing to do so with the possibility of the consequences be evident. The classical theory of Beccaria and others is what our constitution was based upon so as you can see, it has great significance to our society. Humans are believed to act in their own best interests. We have our own free will and we also have a rational side to us. This was the basis of the classical criminology theory. Being the case, this theory emphasized laws that would stress non criminal actions would be in the best interest of society. Punishment and deterrence was an important factor in this theory because the punishment had to reinforce deterrence so people could rationalize the self benefits of criminality from the consequences of criminality. Due to the fact that Beccaria believed that bad laws led to criminality, a lot of his emphasis was based on preventing crime and swift punishment when crime was committed. In his eyes punishment is justified only to defend the peace of society and that society would be motivated to abide by it. This meant that punishment was to treat the criminal, incapacitate them from repeating criminal acts and deter would be criminals. To incorporate these ideas Beccaria believed that punishment should be swift, certain, deterrence, proportional to the crime, clear and based on positive and negative reinforcement. Swift punishment is believed to deter the most. According to Beccaria, when punishment promptly follows the crime, the punishment will be reinforced in a persons mind before they act criminally. A certain punishment is also a form of deterrence because the less would be criminals think they can get a way with, the more they will weigh in the consequences of that action. General deterrence is used for the purpose of setting and example for society. Laws should also be clear I defining  crimes. This will prevent judges from interpreting the law and only allow them to decide if the law has been broken. Lastly, the most effective way in preventing crime is to enact clear laws that reward good behavior and punish bad behavior. The theory of proportionality is another relationship between crime and punishment. The belief is that punishment can only deter if the punishment is proportional to the crime. The punishment must coincide with the crime in that the more serious the crime the more serious the punishment. Lastly, punishment existed to deter people from committing crime and the punishment should out way the gains of committing the act. Beccaria was a believer in that crime was due to unjust laws not because of the people committing the acts. fit the crime. He argued that if the punishment was more excessive than the crime it would be an abuse of power by the state and it would also create more crime. Beccaria was considered the founder of the classical school of criminology. He emphasized human rationality and free will, preventing crime and deterrence of crime. The classical criminology theory was different from the other theories that were introduced to us because it focused on the reasons why people commit crimes not on the deviant behaviors themselves. Beccaria and his followers had a great impact on our country it is what our constitution and current laws are based upon. Internet Encyclopedia of Philosophy.

Power Blackout Preventing By Power Swing Detection

Power Blackout Preventing By Power Swing Detection Power Blackout Preventing By Power Swing Detection  and Out-Of-Step Protection   Power system disturbance, such as fault occurrence, automatic reclosing, and large loads disconnection. These conditions force the generating units to adapt with the new load condition but the generators cant do this instantaneous due to the inertia. This cause a power swing. It may be stable power swing or un stable power swing. In the stable power swing the generator can return to the new equilibrium state. On the other hand, in the un stable power swing the generator cant reach to the steady state operation and run out of step and may lead to the blackout. in the case of power swing the load impedance may enter into the operation characteristic of the distance relay and case unwanted tripping for the transmission lines. So, the distance relay isnt supposed to tripe under the power swing if stable or unstable to give the system the availability to return to its steady state. A power swing block PSB its a function inside the modern distance relays that prevent unwanted tripping by block the tripping signal in case of stable or unstable power swing. However, when the fault happens due to a Power swing it must be cleared very rapidly with high level of dependability and selectivity. Out-of-step trip (OST) in is a function that included in the modern relays to achieve the separation of the power system under the unstable power swing. The major aim of this function to differentiate between the stable and unstable power swing and separate the power system into predetermined zones to achieve the stability and continuity of the service.

Figure 20 Rotor angle and impedance trajectories for unstable power swing. Figure 21 Basic signals for out of step detection. Figure 22 Logic for special out of step tripping. In the previous few years we have suffered from big disturbances in the power system which caused complete blackout and millions of users including the industry have suffered from big economical losses. These disturbances cause big fluctuations in active and reactive power, low voltage, voltage instability and angular instability between the generated power and consumed power which results in loss of generation and load which effected on both sides the power generation and the end customers. During the steady state operating condition, the power systems operates on the nominal frequency (50Hz or 60Hz) +/- 0.02 Hz and Voltage=Nominal voltage +/- 5% [1]. The complete synchronism of nominal frequency and voltage at the sending and receiving ends make complete balance of active and reactive power between generated and consumed active and reactive powers. Power system faults, line switching, generator disconnection, and the loss of large blocks of load result in sudden changes to electrical power, which is due to the causes shown in Fig 1.

[1], [2], [3] Blackout in the Northeastern USA and Central Canada 14 August 2003 Initially the event was the tripping of the power line that caused by the short circuit to ground due to tree contacts. Blackout in the northeastern USA and central Canada was studied by The North American Electric Reliability Corporation (NERC) and some contravention of safety and reliability standards was identified: †¢ following the outage of the first 345-kV line, dispatcher of the power system did not make the necessary actions to return the system to a safe operating state within 30 minutes to fulfillment of N-1criterion which mean Most security rules therefore call for the system to be able to withstand the loss of any single component. When a power system satisfies this criterion, it is said to be N-1 secure †¢ dispatchers of neighboring transmission system were not informed about this situation. †¢ insufficient training of dispatchers. †¢ functionless monitor system in part of the power system. Reliable and safety operation of the power system The North American Electric Reliability Council (NERC) have developed the operating of the system and planning standards to confirm the reliability and the stability of a transmission network that are depend on seven key concepts: Balance power generation and demand continuously. Balance the reactive power supply and the demand to keep scheduled voltages. Monitor the power flow over the transmission lines and other facilities to ensure that thermal (heating) limits are not exceeded. Keep the system in a stable condition. Operate the system so that it remains in a reliable condition even if a contingency occurs, such as the loss of a key generator or transmission facility (the N-1criterion). Plan, design, and maintain the system to operate reliably. Prepare for emergencies Blackout in Italy on September 28, 2003 The situation in the Italian power system before blackout wasnt exception. †¢ total load of Italy was 27 444 MW. †¢ 3 487 MW pump load. †¢ 6 951 MW physical import to the Italian power system. †¢ some transmission lines in neighboring power systems were out of service by reason of scheduled maintenance. †¢ the Italian power system was connected to neighboring power systems via 15 transmission lines. Sequence of events of the blackout in Italy The initial event was the 380 kV line tripping in Switzerland. Fewer than 25 minutes after this event the Italian power system ceased to operate synchronized to the UCTE system. Union for the Coordination of the Transmission of Electricity 03:01:42 the 380-kV line tripping in Switzerland (Lavorno Metlen) line was heavy loaded at 86%. †¢ The cause of tripping a wire contacted to a tree. †¢ The attempts of single-phase auto-reclosing and also the attempt of the operators to put this line back into operation were not successful and the line was disconnected by its protection device, due to high phase angle (42 °). †¢ After the Lavorno Metlen line tripping, the other 380 kV line in Switzerland (Sils Soaza) became overloaded. 03:11 the Swiss dispatch asked the Italian dispatch to reduce the import of Italy by 300 MW (on scheduled value). 03:25:21 the second overloaded 380 kV line tripping in Switzerland (Sils Soaza). 03:25:25 the third overloaded 380 kV line tripping in Switzerland. 03:25:26 the interconnection line Austria Italy (Lienz Soverenze) tripping. 03:25:33 the Italian power system started to disconnect from the UCTE system After disconnection Italy from the UCTE system the frequency in the Italian power system dropped suddenly, caused by the negative imbalance between power injection to the system and system load. The blackout in the Italian power system became within fewer than 3 minutes. 21:40 official announcement about emergency cancellation in whole power system of Italy. Main causes of the blackout in Italy The initial event was the 380-kV line tripping in Switzerland in consequence of the wire the tree contact. The attempts of single-phase auto-reclosing and also attempt of the operators to put this line back into operation were not successful and the line was disconnected by its protection device, because phase angle was too high. We can see two causes: †¢ insufficient protective zone under the transmission lines. †¢ overloaded lines. After the first 380 kV line tripping in the Swiss power system other power lines became overloaded. That means that the safety N-1criterion was non fulfillment in the Swiss power system. We can see other causes: †¢ Violation of basic safety N-1criterion. †¢ high import to Italy. †¢ incomplete information about neighboring power system. †¢ pump load was stopped too late, by automatics. 1.1.2. System disturbance in the UCTE system on 4 November , 2006 The system disturbance in the UCTE system on 4 November, 2006 was the most serious incident in the UCTE system within an interconnected Europe history. The system disturbance started in the German transmission system on 4 November 2006, around 10 p.m. This disturbance split the UCTE system into three separate parts (West, North-East and South-East). More than 15 million households were affected by an interruption of the electricity. The UCTE system resynchronization was completed 38 minutes after the splitting. [4] What happened? On 18 Sept. 2006, the shipyard (Meyerwerft) sent a request to E.ON Netz to disconnect two 380 kV line Conneforde-Diele for the transport of the ship through the Ems River to the North Sea on 5 November at 01:00. As a switching in the last several times. The E.ON Netz operator did a power flow calculation and verified fulfillment of safety N-1criterion using numerical computation. Analysis did not show any problem and so the operator provisionally approved the request of the shipyard and informed neighbouring transmission system operators (RWE Germany and TenneT Niederland). On 3 November (around 12.00) came a new request to E.ON Netz for a time change of two power lines Conneforde- Diele switching on 4 November at 22:00. A provisional agreement was given by E.ON Netz after a new analysis. But RWE and TenneT operators were not informed about this change at the same time. Only at 19:00 on 4 November E.ON Netz informed TenneT and RWE TSO about the new time for switching off the Diele -Coneforde line. At 21:29 according to the load flow calculation made by E.ON Netz did not indicate any violation of limit values. But N-1criterion was checked without numerical computation, was checked based on an empirical evaluation of the grid situation only. Sequence of events †¢ At 21:38 a 21:39. power lines Conneforde-Diele were disconnected. †¢ At 21:39. after the switching operation, two 380 kV lines was overloaded. †¢ At 21:41. RWE dispatcher informed E.ON Netz about the safety limit value on the line Landesbergen-Wehrendorf (an interconnection line between E.ON Netz and RWE TSO). Later investigation uncovered different protections setting on this line. †¢ Between 22:05 and 22:07, the load on the 380 kV line Landesbergen-Wehrendorf increased and the RWE operator called E.ON Netz at 22:08 with the request for urgent intervention due to return to the stable grid condition. †¢ E.ON Netz made an empirical assessment of corrective switching measures without making load flow estimation for checking the N-1criterion. E.ON Netz expected that coupling of the bus-bars in the substation of Landesbergen would reduce of load on the 380 kV line Landesbergen- Wehrendorf. But this line was overload more than 100% and so was tripped and the other lines became overloaded. †¢ At 22:10:28 the UCTE system splitted to three areas after the power lines switching in E.ON Netz, RWE, the Austrian power system and after disconnection of interconnection lines: Croatia Hungary and Marocco -Spain. The initial event of the system disturbance in the UCTE system was scheduled switching off two power lines. Main causes The investigation identified two main causes of the disturbance as well as some critical factors which had significant influence on its course: non fulfillment of the N-1criterion or verified its fulfillment without numerical computation. †¢ insufficient co-ordination between the transmission system operators. †¢ dissatisfied power plant operation in emergency: tripping of generation units (particularly wind power plants) during disturbance and uncontrolled reconnection of generation units. †¢ limited range of action available to dispatchers. †¢ insufficient training of dispatchers. 1.2. Blackout Causes and Risks A blackout is a power outage. This state means the loss of the electricity supply for a part of the power system or the whole power system. A. Blackout Causes Natural causes Lightening. Rain. Snow. wind storm. Technical Failures Transformer faults. Short circuits. Human error Error of judgment. Insufficient co-ordination between the transmission system operators. Insufficient training of dispatchers. Terrorism Bombing. cyber-attacks. B. Blackout Risks power system equipment damage. heavy economical losses. jeopardy of economy functioning. life paralysis in stricken parts of country. Several blackouts cases became in the world of last years. Causes of these disturbances were various technical, bad weather conditions, human failing. C. Some impacts of Northeastern Blackout Ford Motor Company The stoppage of factorys furnace cause to convert the molten metal to solid metal. The company reported that it need a week to clean the furnace. Marathon Oil Corporations The blackout was responsible for making suddenly shutdown procedures at Marathon refinery. in those procedures, a carbon monoxide boiler failed to shut down correctly, causing a small explosion. As a precautionary measure, the police vacate one-mile sector around the complex. Daimler Chrysler Daimler Chrysler lost production at 14 of its 31 factories. 6 of those were assembly factories with paint shops. The company reported that, in total, 10,000 vehicles were moving through the paint shops during the blackout had to be scrapped. New York City New York Citys mayor estimated that the city would pay almost USD 10 m in overtime related to the outage. Airports Airports were closed in Toronto, Newark, New York, Montreal, Islip, Cleveland, Erie and Hamilton. Together they cancelled over 1,000 flights 2.1. Introduction Under steady state conditions the power generation and the load are balanced and the power systems operate in nominal frequency 50 Hz or 60Hz with some deviations 0.02Hz for the large system and 0.05 for the small system. Taking into consideration the two-machines shown in Fig. 2, the power transmitting can be denoted by the following equation: Where: ES is the voltage of machine S ER is the voltage of machine R ÃŽÂ ´ is the angle by which ES leads ER = QS-QR QS is the rotor angle of machine S QR is the rotor angle of machine R ZT is the total impedance between the two machines consisting of ZS, ZR, and ZL ZS + ZL + ZR ZS is the impedance of source S ZR is the impedance of source R ZL is the impedance of the transmission line The Power angle curve in Figure 3 clears the relation between the power transmit and the angle ÃŽÂ ´ (the angle between the two ends). The relation clear that the power transmit increase with nonlinear direct proportion with the angle ÃŽÂ ´ when ÃŽÂ ´ lie between 0 ° : 90 ° . After ÃŽÂ ´ equal 90 ° the power decrease with nonlinear inverse proportion with the angle ÃŽÂ ´. The power system are worked well at the point of maximum power at ÃŽÂ ´ = 90 ° so The maximum power is presented as the following equation: Power Swing definition It is a changing in the Electrical power due to the changing of the rotor angle (ÃŽÂ ´) either Increasing or decreasing response to : line switching, Load disturbances , loss of generation, short circuit faults and other power system disturbances. During the large disturbance in the power system the transmit electric output power suddenly decreased from P0 to Pf as shown in Fig.4 but the mechanical torque (that connected to the generator and equivalent to the output electrical power P0 at the moment before reducing the electrical power) cant reduce suddenly to equivalent Pf so this unbalance cases accelerating in the rotor of the machine and increasing in the angle (ÃŽÂ ´). The assume of this analysis is neglects the operation of the voltage regulator that control on the excitation and change the machine voltage, and the governors that change the mechanical input power If the fault is cleared at the point of ÃŽÂ ´c the output electric power will increase and become greater than the input mechanical power so the machine will start to decelerate but because of the inertia the machine rotor cant decrease suddenly and reached to ÃŽÂ ´e. Assume area 1 refer to the accelerating energy, and area 2 refer to decelerating energy, so when the fault cleared quickly the two areas can be equal before the angle reach to the limiting angle ÃŽÂ ´L and the system will return after some oscillation to the last operating point at ÃŽÂ ´0 and that call Stable power swing. On the other side if the fault didnt clear quickly and spend more time, the angle ÃŽÂ ´ will move far away enough to make the two areas (accelerating area de accelerating area) not equal before the angle reaches to ÃŽÂ ´L as shown in Fig. 5 and due to the inertia the the angle will reach to the limiting angle and after this point the electrical output power will decrease again to be less than the mechanical input power so the machine rotor will accelerate and the rotor angle will increase above 180 and the pole slipping will happen . this case called out of step condition or unstable power swing condition Power Swing Effect on the Distance Relay Under Steady State Operation the impedance of the load not enter into the operation characteristic of the distance relay but in the case of power swing the load impedance may enter into the operation characteristic of the distance relay and case unwanted tripping for the transmission lines, and may be cause cascading tripping and stoppage of major sections of the power system. The distance relay isnt supposed to tripe under the power swing if stable or unstable to give the system the availability to return to its steady state. A power swing block PSB its a function inside the modern distance relays that prevent unwanted tripping by block the tripping signal in case of stable or unstable power swing thus, The Power Swing Block function is used to differentiate between the power swing and the fault. However, when the fault happens due to a Power swing it must be cleared very rapidly with high level of dependability and selectivity. The zones must be separated hoping to avoid causing large deference of the rotor angle between groups of the generators and loss the synchronism between them, equipment damage and the blackouts. Perfectly, the power system should be separated into predetermined zones to achieve a balance of load-generation in each of the separated zones. In some cases, load shedding is essential to avoid a whole blackout of the area where the load of the separated area is more than the local generation Controlled tripping of the power system relays in the case of an Out-of-Step condition is very essential to prevent extensive outages, equipment damage and shutdown of large areas in the power system. Out-of-step trip (OST) in is a function that included in the modern relays to achieve the separation of the power system under the unstable power swing. The major aim of this function to differentiate between the stable and unstable power swing and separate the power system into predetermined zones to achieve the stability and continuity of the service. Power Swing Detection Methods. Following is a brief discussion of the methods that have been used for detecting power swings and schemes used for OSB and OST functions. Traditional method based on rate-of change of impedance and the recently method is Power-Swing-Detection Algorithm Based on Continuous Impedance Calculation. 2.2.1 Traditional Rate of change of Impedance Schemes for Detecting Power Swings. In the conventional method, the relay measure and calculate the positive sequence impedance and the change rate of the impedance. During the steady sat operation the measured impedance depends on the load impedance and the distance between the protection zone of the distance relay and the point of measurement. The impedance move in trajectory depends on the operation case. In the case of the fault if the impedance moved rapidly to the fault zone. On the other case during the power swing the impedance moved slowly at some trajectory with a rate depend on the slip frequency between the generators. Thus, the variation of the impedance movement speed used to distinguish between the power swing and the faults. The concept of this method that using of two measuring impedance and separated them by ΆZ and used a calculated timer. When the measured impedance moved through the first one the timer will start running. If the measured impedance cross the second impedance before the time r expire, that indicated to a fault case. If the timer expired and the impedance didnt reach to the second impedance that indicated to a power swing case. Two-Blinder Scheme for PSB and OST Functions The two blinder scheme of the rate-of-change of impedance method is used in many relays, separated by ΆZ, and a calculated timer TOSB. The two-blinder scheme is shown in Fig. 7. This figure shows Two parallel blinders are on the right side of the X-line impedance and another two parallel blinders are on the left side. The timer TOSB is start running when the impedance move through the outer blinder During the fault condition the impedance moved rapidly through the outer blinder to the fault zone and cross the inner blinder before the TOSB expire. On the other case during the power swing the impedance moved slowly through the outer blinder and stay between the two blinders even TOSB will expire. This scheme can be used for a power swing blocking function to block the distance relay to prevent unwanted tripping. During Power Swing Blocking declared a reset timer should be used in order to force the relay to delay the assert when TOSB expired. The Out-Of-Step tripping (OST) can use the previous scheme expect that the calculated timer for out of step (TOST) is shorter than TOSB. In the case of power swing the impedance locus cross the outer blinder and at this point the timer will start running. If the timer TOST expires before the impedance locus cross the inner blinder, the power swing condition will declare, and if the impedance locus cross the inner blinder before timer TOST expires, the out of step condition will declare. The Out-Of-Step tripping function can be set to tripe instantly or wait for a time. The Instantly tripping referred to as predictive tripping or early tripping. The other case is referred to as delayed tripping. In some applications, the tripping is required only when the out of step condition occurs a determined number of times. It is essential for some application to use both OSB and OST functions, and it available to use them in the Same relays using the two blinder scheme technique. According to difference in speed of impedance trajectory in the case of stable power swing and unstable power swing, two timers are required TOSB and TOST whereas TOST is shorter than TOSB to be fit with the rapidly speed of the impedance trajectory in case of unstable power swing 2.2.2. Power Swing Detection Algorithm Based on Continuous Impedance Calculation The traditional methods of power swing detection are depend on a complex study for the power system to reach to the correct settings, but the setting are fixed and not adapt to any change in the system condition because of it is not possible to study the system under unstable power swing. therefore, the power system study doesnt deem the worst cases and the bad conditions, so in the case of power swing or out of step condition it may lead to unwanted tripping. The following method described below solves these problems. It is based on a continuous impedance calculation [5]. This method has the following features: It is not required for settings or complex calculation detect the power swing with frequencies range from 0.1: 10 Hz. Detect the power swing in the case of single-pole open condition or fault condition. Unblocking of distance protection relay if there both faults and power swing. Out-of-step tripping during unstable power swing. The Continuous Impedance Calculation method depend on taking four sample of the impedance per one cycle of the power system frequency the three phase each phase separately. During the power swing the impedance trajectory moved on an oval path, and when it enters the power swing area, as shown in Figure 8, the algorithm of power swing start its analysis for each phase and calculate the power swing area automatically. In the case of power swing, the power swing detection will detect it, and stay active even if the trajectory of the impedance leave the power swing zone. The algorithm computes the new values of R X, and compares them with the previous values that placed in the memory. The main criterias of the power swing detection methods are monotony, continuity and smoothness. The thresholds are calculated dynamically. This automatic adaptability to the trajectory speed change, enables the algorithm to detect the low frequency and the high frequency power swing. Monotony: The algorithm will check the direction of the derivat
