Free Essays on SAN Benefit Analysis

SAN Benefit Analysis Executive Summary Over the last few years the open systems portion of ENTER_NAME_HERE’s Data Center has shown tremendous growth, in both the number of applications supported, and the amount of servers required to support the additional demands. In order to efficiently support our current environment, and be positioned for future growth, deploying a SAN (Storage Area Network) is necessary. A SAN is a high-speed network that joins together storage systems and servers utilizing a fiber backbone with switches and hubs. Once deployed, SANs operate as a utility making additional storage accessible to resource and application servers as needed, routing data to servers on demand, and routing data from disk to tape servers for archiving. A SAN is an alternative to traditional server-attached storage. High-performance SANs utilize fiber optic network connections routed by a switch, often dedicated to guarantee quality of service. Additionally, storage can be managed more efficiently, allocating add itional storage requirements on-demand, instead of dedicating â€Å"stranded storage† to particular servers, thus the ability to consolidate storage pools. Storage consolidation makes good business sense. It can help dramatically reduce the high maintenance cost of proliferated storage, more fully utilize storage assets, and improve the quality of storage services that Distributed Technology offers to the enterprise. Migrating to consolidated storage architecture will allow Distributed Technologies to provision more storage for less cost. Efficient and flexible storage systems have a direct impact on key business indicators. Consolidated storage systems reduce indirect costs, which are well known to be onerous in IT infrastructure investments. These systems are designed to provide the availability and scalability that keep enterprise business systems up and running through periods of growth and retreat. Addition...

While most signs have one very prominent trait (for example, Capricorns are notoriously ambitious), Geminis, those born between May 21 and June 21,can be social, talkative, and whimsical, but they can also be indecisive or nosy. Some Geminis love to be the center of attention; others love to gossip. They’re typically passionate yet easy-going beings who are always down for an adventure or intellectual conversation.

Gemini men tend to be very outgoing, almost to a fault.

If you really want to get to know them, you should spend time with them one on one. Gemini men are also huge flirts, so if you're dating a Gemini man, maybe don't introduce him to your hot friends. Gemini women are very passionate about life but are very hesitant when it comes to love.Due to their intelligence and indecisiveness, Gemini women agonize about the important decisions in their life. If you're dating a Gemini woman, be patient with her; it may take her longer to commit to a serious relationship.

As Project Management evolves a new set of issues is demanding Essay - 1

As Project Management evolves a new set of issues is demanding attention - Essay Example Consequently, complexity and drastic change build a high-risk environment wherein decision makers have little faith about the future. They view experiences through dense perspectives and base their decisions on guesswork and small measures of certainty (Lewis 2007). Making things more difficult is the aggressively competitive environment that has emerged with the introduction of the Internet and the spread of globalisation. This competitive environment has motivated a fascination with winning customers’ hearts and minds. In the contemporary business environment, customer satisfaction rests at the core of most business endeavour (Lewis 2007). This paper will explore the new business climate and their implications for project management. The traditional saying â€Å"the only constant is change† (Frame 2002: 26) ceases to be a witty oxymoron and is now a prevailing reality in contemporary business life. Untapped change is a primary determinant of project failure. Changes in markets, technology, regulations, budgets, and personnel motivate changes in project requirements and demands. Project personnel discover themselves operating in ‘rubber baselines’ (Frame 2002: 26). The abundance of alternatives is obvious in project management. For instance, there are several workable ‘scheduling software packages’ (Howes 2001: 13) being recommended by suppliers. How does an individual choose from such diversity? A great deal of the complexity of present projects is linked to the diversity of alternatives confronting all project actors, from customers to team members to project managers. These alternatives cover all project features. For instance, consider the alternatives related to the buying of a product or service (Howes 2001). Practically any product or service to be used on a project has a variety of suppliers or providers, each with its distinct qualities (Frame 2003). In

Gender-role in Advertisement Essay Example for Free

Gender-role in Advertisement Essay This paper explores gender-role in modern advertisement. Sample modern-day advertisements will be analyzed in relation to gender-roles. Gender-role refers to a person’s way of actions and thinking that is identified as either related to male or female characteristics (Haig, 2004). It is a set of expectations on how females or males should think, behave, and feel. It is in the adolescence stage that male and females start to define their roles while their gender is intensified by conformity to transitional gender-roles in during puberty (Hill Lynch, 1983), which indirectly signals that they begin to act in ways that resemble the stereotypic female or male of their culture (Huston Alvarez, 1990). In addition to the demands of work and changing trends in the society and the increased number of employed mothers in the mid twentieth century, adolescents exposure to the media is considered to have a possible impact on their attitudes and perceptions about gender relationships, identity formation, and gender-roles (ODonnell ODonnell, 1978; Durkin, 1986; Lovdal, 1989; Richards Duckett, 1994; Dietz, 1998; Hovland et al. , 2005). The effects of advertisements to the perpetuation of gender-role stereotypes have received considerable importance in research and it has been debated whether it stereotyped advertisements have long term or short term impact on people’ own gender-role and whether advertisements with stereotypic portrayals gain more profit or does not have significant influence in people’s buying behavior at all. Effects of media in gender-role There are many factors that that affect gender-role development and the media is considered to be one (Golombok Fivush, 1994; Durkin, 1995). Dietz (1998) asserted that the media, in addition to environmental or social factors, affects people’s perception of gender-roles. The impact of advertising on audiences is often explained by social learning theory or by theories that are based on it. The argument is that, as people are repeatedly exposed to advertising images, they tend to internalize the advertisers views of themselves and others. The more ubiquitous the images are in advertisements, and the more frequently they see the advertisements, the deeper the audience identifies with the images. In addition to social learning theory (Bandura, 1977), framing research or frame analysis, introduced Goffman (1974), was used to obtain empirical evidence regarding the effects of media portrayals in people’s thoughts and consciousness. Framing assumes that the media frame reality is used to explain how people perceive and think about gender-roles because of the things they see and experience. Framing is used as a remedy sort in selecting a particular aspect of a perceived reality in order to emphasize, convey, or interpret something. However, framing may directly or indirectly influence people’s judgments on recognizing ideas presented in advertisements (Entman, 1993). Another issue on the effects of media is identified by Mead (1962) in his theory, arguing that individuals’ characterizations in the media affect children’s attitudes, relationships with other people, and behavior expectations. When traditional feminine or masculine roles become distinctive and children starts to identify with a particular gender-role, they are likely to expect specific characteristics and behaviors from females and males. Gender-role stereotyping negatively affects young individuals’ attitudes towards males and females since traditional portrayals of women are usually portrayed as dependent, obtaining approval from family and males, weak, victims, supportive of mens roles, sex objects, and adornment rather than individuals (Hall, Iijima Crum 1994; Artz, Munger, Purdy, 1999). As a result, these negative or substandard characteristics of women adversely affect children’s perception that women may ever find it difficult to attain gender equality and function as effective as men do in the society. This female portrayal restricts young females to think of achieving beyond their potential because many attributes, activities and traits are being designated as inappropriate for their gender (Dietz, 1998). Traditional stereotyped gender-role portrayals in advertisements Most advertisements portrayed both males and females stereotypically. Since 1950s, significant changes in gender-roles have occurred as the division of labor has become less distinctive and the entry of increased number of women into the workforce where professional positions, which were used to be exclusively for men, have opened opportunity for them to progress. Images of men and women in advertising in the early times have been heavily stereotyped. Men were depicted as independent, active, assertive, work-oriented while women were portrayed as dependent, passive, and domestic. Advertisements in the 1970s to 1980s continued to portray gender-stereotyping due to the difficulty of presenting people without specific gender-roles, especially when advertising specific products of particular gender. The strategies of advertisers in attracting people’s intentions and behaviors were more likely to favor gender-stereotyped representation since the public was more familiar and comfortable with gender-stereotyped advertisements (Morrison Shaffer, 2003). Gender portrayals in the context of advertisements were found to be predominantly stereotypic with dominant males and nurturing females in the mass media, music, film, as well as the print media. Although changes in the society and culture have been apparent, advertisements still rely upon women’s roles as subordinate. Women’s subordination was a useful tool in selling a wide variety of products such as alcohol, medicine, cigarettes, perfume, and vehicles. Constant exposure to derogatory portrayals of females in advertisements may result to socially induced depression and lowered levels of aspirations in achieving ones goals. Women portrayal as subordinates has been consistently practiced and presented in advertising until today although some changes and reversions have been observed (Mclaughlin Goulet, 1999). Advertisements usually portray men as being strong who are expected to have jobs that require much physical strength. They are portrayed as being the authority, dominant, having higher intelligence, becoming public figures, belonging to upper-middle class, being able to take medicine, law or business courses, aggressive, and sometimes gentlemen or bad guys. At home, men are portrayed to use car wax, auto parts, carpentry tools, motor oil, and lawn mowers. Women are rarely depicted as professionals in advertisements (Dietz, 1998). When women in advertisements are presented as professionals or experts in the products they advertise, they are often backed up by male figure or an authoritative male voice-over to strengthen the efficiency of convincing the audience since males were viewed as the authority (Lovdal, 1989). In traditional male magazines (e. g. , Esquire and Field Stream), gender-role stereotyped advertisements that portrayed men with masculine or manly activities have not decreased as much as the traditional female and general interest magazines. Although there have been some trends toward less stereotypic portrayals of masculine images in some print media advertisements, the traditional stereotype of the male gender still provides cultural representation (Furnham Thomson, 1999) Women are stereotypicly depicted in relation to beauty, physical attraction, family, domestic responsibilities, parenting, occupations such as teacher, waitress, masseur, bride, actress, secretary, vendor, household cleaners, maid, model, guest relations officer, and the like, as well as negative representation like evil, witch, possessions of men, passive, deferent, object for men’s pleasure. At home, women are portrayed to take care of every member, do all the chores, and maintaining relationships. They are often portrayed as supportive wives, mothers, sex objects, dependents, lack exploration, skills, knowledge, credibility, self-expression, and sense of mastery. Advertisers market products in magazines, like in television, using young, professional women as a product of beauty techniques and methods in order to attract and keep handsome, lucrative, and sophisticated men. Comic strips and children’s books also continued to adopt and support traditional portrayals of women in the society. For instance, illustrations show traditional female activities or a situation in which there is a dutiful wife in the bathroom or kitchen wearing an apron to model cleaning products, kitchen wares and appliances or food (Dietz, 1998; Peirce, 2001).

Two Perspectives of Organization Theory Essay -- Business Management

Organization theory is the body of knowledge related to the examination and analysis of both the internal workings of organizations and their interactions with their external environments. This knowledge is generated either through practical experience or through scientific inquiry. Organization theory is also concerned with applying this knowledge to designing and managing organizations. Contrary to what the term â€Å"organization theory† might suggest, the literature of this field of study teems with a variety of organization theories. Each theory offers a perspective for understanding organizations. The wealth of perspectives in organization theory stems from the diverse, complex, and dynamic nature of organizations and the wide range of academic disciplines underlying the field of organization theory. For any field of study as diverse as organization theory, controversies are bound to occur. Such a clash of perspectives occurred when Herbert Simon published â€Å"The Pro verbs of Public Administration†---a biting criticism of classical organization theory as exemplified by the work of Luther Gulick. I shall first summarize Gulick’s and Simon’s central ideas about organizations, laying the ground to compare and contrast their approaches. Then I will consider Simon’s critique of Gulick, and to be fair to Gulick, we shall also examine arguments from an article written in Gulick’s defense by Thomas Hammond. In the course of the discussion of the Gulick-Simon debate, I will take the liberty to interpose my comments on the arguments put forth. My global comments on this debate are collected toward the end of this think piece. Let us first consider Gulick’s perspective on organizations. Gulick’s work on organization theory belongs t... ...e possibility for cross-fertilization between the existing paradigms exists. Perhaps, the best that can be done is to establish frameworks in which multiple paradigms provide different viewpoints from which to examine the complexities of organizations.

Air Pollution from World War Ii Production

Air pollution From Wikipedia, the free encyclopedia Jump to: navigation, search Air pollution from World War II production Smog over Santiago, Chile Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth.Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems. Indoor air pollution and urban air quality are listed as two of the world's worst pollution problems in the 2008 Blacksmith Institute World's Worst Polluted Places report.

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

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

Catcher in They Rey – Holdens Contradictory Views of the World

With close reference to pages 183-186 analyse Salinger’s use of language and structure, exploring Holden’s contradictory view of the world. On Page 183 Holden says ‘you could tell the two hot- shots I was with weren’t enjoying it too much. They stayed close as hell to me, and the one that didn’t talk at all practically was holding onto my sleeve’. Holden calls them ‘hot shots’ because they acted phony by bunking school and then lying about there being no school. (P182). Throughout the novel, Holden seems to have a problem with the whole idea of ‘phoniness’, yet at times, he himself acts phony.Holden considers movies to be extremely phony and criticises his brother because he moved to Hollywood. Holden emphasises his hatred for Hollywood and movies throughout the novel. Holden states his problem with phonies on page 184 when he says ‘I’d have this rule that nobody could do anything phony when they visited me. If anybody tried to do anything phony, they couldn’t stay’. He constantly demonstrates the idea that if people are ‘phony’ it’s a bad thing. We see this on pages 72/73 when he is talking about Ernie.He says that Ernie ‘is a terrific snob and he won’t hardly even talk to you unless you’re a big shot or a celebrity or something’. In this sentence, Holden implies that just because Ernie is good at playing the piano he thinks he can treat people badly, as if he is better than them. This seems to be Holden’s main dislike about ‘phoniness’, the fact that people act ‘phony’ because they think they are better than you. This is also shown on page 23 when Holden says that stradlater fixed himself up all the time because he was ‘madly in love with himself.He thought he was the handsomest guy in the whole of West Hemisphere’. He criticises Stradlater’s love for himself because h e sees this as an act of ‘phoniness’. While criticising people due to their ‘phoniness’ throughout the novel, Holden himself acts ‘phony’ on multiple occasions. On pages 48-52, when talking to Ernest Morrow’s mother, he pretends to be a completely different person to himself. He makes up a whole false persona in order to look better in front of Ernest’s mother. His false persona has a different name, and likes Ernest, even though Holden himself doesn’t have a high opinion of him.If somebody else were to do the same thing in front of Holden, he would undoubtedly call them ‘phony’. In chapter 17, when Holden goes on a date with Sally Hayes, he speaks just as posh as Sally does. This is shown when he says ‘swell to see you too’. Again, Holden is putting on a false persona in order for Sally to like him more. Throughout this whole chapter, Holden constantly criticises Sally on the way she speaks and ac ts, yet speaks and acts just like she does. By doing this, Holden is contradicting himself.He doesn’t seem to realise that he is acting just as ‘phony’ ads Sally is. Holden seems to act this way in front of most girls. I think he does this because he sees other guys acting the same way with girls and he naturally copies them because he doesn’t know how else to act. As a result, he contradicts himself often, but he just doesn’t realise this. On page 183, Holden states that the tomb was ‘so nice and peaceful’, yet he goes on to say that ‘you can’t find a place that’s nice and peaceful because there isn’t any’.Again, Holden is contradicting himself, but in a different way. He always seems to radically change his views based on little things. On page 184, he talks about his ideal future living in a cabin away from the world. When talking about how his family could visit him he says that he would let D. B. c ome and visit him for a while if he wanted ‘a nice, quiet place for his writing. ‘ Again he is contradicting himself because he is now saying that there is a place which is nice and peaceful, even though he previously stated that there isn't any.This is a clear example of Holden's unstable state of mind, because he doesn't remember what he previously says and he doesn't seem to have any set views as he is always contradicting himself. Loneliness is a key theme in the novel, and it is represented through Holden's contradictions. On page 184, when talking about his ideal future living alone in a cabin, he says, ‘I'd ask them all to visit me sometime if they wanted to, but I wouldn't insist or anything. ‘ This basically shows Holden's desperation for any type of relationship.Although he wants his family to visit him and keep him company, he doesn't want to admit it and therefore acts like he would invite them round as a favour to them, when really, it would make him feel better. On page 186, Phoebe is angry at Holden and Holden gets upset and feels guilty. this shows that he actually cares for Phoebe, even though he would never admit it. He shows this often throughout the novel when he talks highly about her. This idea is also shown on pages 122-123. Holden is so desperate for company that he just contacts anyone he could think of in order to have company.Even though he criticises these people based on their ‘phoniness', he still wants their company. This reoccurs on page 134. Holden spends all that time criticising Luce, yet ends up practically begging him to stay with him because he is lonely. He even admits his loneliness to Luce . ‘I'm lonesome as hell, no kidding'. This happens a lot during the novel. In chapter 10, Holden meets three girls, who he refers to as ‘pretty ugly' and ‘the three witches'. He spends the majority of the chapter pretending to like them in order to have company, even though he constantly criticises them to us.He constantly complains to us about things that they do, yet at the end of the chapter on page 67 when they say they had to leave, he says that he ‘tried to get them to stick around for a while'. This scene links together the last two points that I mentioned. Holden doesn't actually like the girls, yet he pretends he does so that he can have company. He also creates this false persona that is interested in the three girls. In order to do this, he had to use techniques that he has learnt from other people, even though he describes these other people as ‘phony'.Because he so socially unable, he takes techniques from others. What he doesn't realise is that by using these techniques, he himself is being a ‘phony'. You could say that deep down he knows that he does this a lot, yet he doesn't want to admit it to himself. In conclusion I think that Holden is highly contradictory about everything due to his troubled and confused state of mind. I thin k this is caused by the changes they are taking place in his life, such as getting kicked out of schools a lot and not understanding sexual relationships/feelings.

Oates and Where are You Going, Where Have You Been

Oates and Where are You Going, Where Have You Been You Arent Going Anywhere: A Feminist Critique of Joyce Carol Oates The story â€Å"Where Are You Going, Where have You Been,† by Joyce Carol Oates, is the story about a young girls attempts who tries to gets free from the surrounding and acts accordingly, drawing the attention of a dangerous man. The main character in the story, Connie, lives in a small town with her mother, father, and Connies older sister. Although Connie is fifteen, she realizes that males find her attractive. She defines herself in opposition to her mother and sister, the former used to be beautiful, and the latter never was.Advertising We will write a custom essay sample on Oates and Where are You Going, Where Have You Been? specifically for you for only $16.05 $11/page Learn More The unfortunate aspect of the story is that Connie plays up her attractiveness and plays the roll that other people want her to have, the one of a beautiful girl. Using a feminist critique, we can see h ow Connie leads herself to her unfortunate fate by allowing to be unwittingly trapped in the patriarchal gender roles of society. The photograph of Connies mother where she was younger is a symbol of the emptiness that comes from defining oneself solely through ones looks. Connies mom was a very attractive woman in her youth, but growing older, she lost those looks. When the mother sees the pictures of her daughter, she recognizes the beauty that she once had but lost. This is the major loss for the mother, since she apparently never learned to define herself in any other manner. Once her looks were gone, there was nothing left of the woman. As such, she envies her own daughters physical attractiveness and acts in a mean way towards Connie. Her mother, who noticed everything and knew everything and who hadnt much reason to look at her own face, is always scolding Connie for it. Stop gawking at yourself. Who are you? You think youre so pretty?. (Oates) Since her mother is obviously j ealous of her, Connie feels as though she is right in valuing her looks in the way she does. To Connie, physical attractiveness is so important that nothing else seems to matter, so she doesnt hold any regard for what other people might have to offer. Instead of listening to anything that her mother has to say, Connie feels as though she can simply dismiss anything that her mother might have to say to her, which is simply another way for a woman to keep herself trapped. For example, she can hardly believe that the woman in the pictures is really her mother: Her mother was pretty too, if one could believe those old snapshots in the album, but now her looks were gone and that is why she has always been after Connie. For Connie, being beautiful is simple, the state which you are to inherit, and like all young and immature people, she doesnt have any idea how easily it can be lost, whether slowly over time like her mother did, or having it suddenly and violently ripped away from her. Th e thing that she ran away with a boy foolishly led Connie to believe that she matured further than her older sister and anyone else in her own age group. It appears to almost be a game for her, but when she finally realized what the price of her desires were, it was too late.Advertising Looking for essay on american literature?

Get your first paper with 15% OFF Learn More Being only fifteen, Connie has yet to realize that she has defined herself by the way other people view her, which is through her looks only. She has become trapped in her own assets, and this stunts her growth as a whole person. While she views herself as using these tools to her advantage, in reality she is doing nothing but harming herself and her ability to survive in life. While at times Connie gets excited and enjoys the attention that she receives, she quickly realizes how terrifying unwanted attention of this kind from the wrong person can be. When Arnol d Friend tells her that he was Gonna get you, baby, she quickly realizes that not only she is trapped, but she has been trapped all that time by allowing herself to be defined in such a manner. What Arnold does is to treat her as a mere physical attribute, thus, neglecting her personality. He thinks he has the right to do the horrible things with her: Arnold Friend stabs her with words again and again with no regret. After that she becomes withdrawn form the rest of the world. Once it happens to her, she no longer has any forces to struggle, live and survive. We can see Connies unequivocal surrendering and resignation when she allows people to treat her as an object but not a person, that is something that she has been allowing to do to herself all those years unconsciously. At the end of the story, she has completely broken away from herself and any sense of self-identity; she views the events as though they are happening to somebody else and not to her: She put out her hand agains t the screen. She watched herself push the door slowly open as if she were back safe somewhere in the other doorway, watching this body and this head of long hair moving out into the sunlight where Arnold Friend waited. (Oates) The story does not have a clear ending, we see Connie fully losing herself and becoming fully trapped within this patriarchal system represented by the terrible and dangerous Arnold Friend. This main aspect of Connie completely breaking away from herself and surrendering herself and her sense of identity is what we need to realize from this story which shows the readers the dangers that women face in a prison of patriarchy.

Menes - Legend of the First King of Egypt

Menes - Legend of the First King of Egypt In Egyptian legend, the first king of Egypt was Menes. At least, Menes is the form of the kings name that was used by the 3rd century B.C. historian Manetho. Two other first dynasty kings names are associated with Menes, Narmer (as in the Narmer Palette) and Aha. The Greek historian Herodotus calls Menes Min. The Jewish historian Josephus calls him Minaios and the Greek historian Diodorus Siculus refers to him as Manas. There are various etymologies for the name, including an attempt to connect Menes with the name of the city he founded, Memphis, which he reclaimed by means of dam construction. Diodorus Siculus refers to Manas as the first law-giver. Menes is credited with introducing papyrus and writing (Pliny), founding cities, building dikes and more. Manetho says Menes dynasty had 8 kings and that a hippopotamus carried off Menes at the end of his life. How Menes died is part of his legend, with the hippopotamus version being only one possibility. Pharaoh Menes death after an anaphylactic reaction - the end of a myth says Diodorus Siculus wrote he was chased by dogs, fell into a lake, and was rescued by crocodiles, leading scholars to think possibilities include death by dogs and crocodile. The article, as is fitting an article on the topic of allergy, explains why some think Menes was killed by an allergic reaction to a wasp sting.
