Business in context 2 - Essay Example most 90,000 workers in the year 2007 and according to Challenger Gray and Christmas, plant closures by Ford and General Motors will ripple through the economy possibly resulting in more job cuts in the coming year. (www.allbusiness.com) The world economic crisis has hit the car industry with real intensity forcing the major car companies to adopt strategies of short time working, redundancies or closures. (www.fifthinternational.org) The automotive sector is one of the largest and most multinational of all industries which is the key indicator for economic growth in regard to GDP of many countries. The car industry is important in view of its employee strength, its contribution to countries development, assets and total sales which can be known from the fact that in the year 1999, four of the top ten companies in the world included General Motors, Ford, Toyota, and Chrysler.(www.eurofound.europa.eu) The Koontz, H and Weihrich, H. (2006) stated that car industry may be indicative of how many industries become globalized making it difficult to predict the future. It is further stated that countries such as China and India will be the drivers not only of economic growth in general and car industry in particular. The Economic Intelligence Unit had predicted that 40% of the car sales will be in Asia by 2020. Jian Suan (2006) stated that in early 2000s China was a dream market for many multinational auto companies with only 24 cars per 1000 residents as compared to 700 cars per 1000 residents in United States and worldwide average of 120 cars, the China market was widely regarded as the largest growth opportunity. China reported an increase of 6% in global auto market from 4% in the year 2001 to 10% in ranked equally with Japan which reported a decrease of 1%. Carlos Gomes (2010) reported that global car sales continued to gain momentum with more than double of sales taking place in China, the world’s largest auto market. The auto sales in United States too reported

Discuss the role of magistrate and jurors in the legal decision-making Essay

Discuss the role of magistrate and jurors in the legal decision-making process - Essay Example Consider the disadvantages of the services that the magistrates and jurors provide in the legal decision-making. The contribution of magistrates and jurors to the legal decision-making will be assessed based on the consideration of the advantages and disadvantages of the services they provide in the legal decision-making. Courts and Legal Services Act 1990- includes provisions on appointments of District Judges and the courts’ procedure, specifically in respect to distribution of civil business between the County Courts and High Court. The Contempt of Court Act 1981- states that disclosure of anything that took place in the jury room amounts to a contempt of court and is therefore a criminal offence. Juries Act 1974- consolidates particular enactments relating to jury service, jurors, and juries with improvements and corrections made under the Consolidation of Enactments Act 1949. The Tribunals, Courts and Enforcement Act 2007- contains fundamental legal procedures and courtsà ¢â‚¬â„¢ structure Condron v UK (2001) 31 EHRR 1- provides an example of how magistrates and jurors legal decision-making process can lead to breach of human rights. ... Summary of the arguments that point out that, indeed, the magistrates and jurors play a very critical role in the legal decision-making process. Question 2 Introduction The magistrates and jurors play a very important role in the resolution of both criminal and civil cases (Elliott and Frances, 2008, p. 12). For over 1000 years, jurors have formed a fundamental part of the English Legal System and have played very important role in the legal matters’ resolution for many centuries (Slapper and David, 2001, p. 35). Similarly, magistrates have also been playing a very instrumental role in resolving criminal and civil cases and have in recent years become extensively important in many of the cases in the English Legal System. The jurors form a jury an arrangement that is made up of a specific number of ordinary individuals who are called for service on any legal matter (Forsterlee & Horowitz, 1997, p. 307). Jurors’ main role is to bring their perspective to a case as lay pe rson with no knowledge of law. Jurors combine their common sense, wisdom, and experience to decide the facts relating to a particular case in order to reach a verdict (Cownie et al, 2007, p. 51). It is worth noting that jurors simply decide the verdict and not the law; the jury decides the question of the defendant guilt while the judge decides on the point of law. In respect to magistrates, they are local people volunteering their services. Magistrates do not have formal legal qualifications and are chosen based on their local knowledge. They sit in the magistrates’ court as a bench of two or three magistrates (Sanders and Young, 2004, p. 97). The court trial involves several processes. The initial process within

Marine Pollution Causes Effects And Control Environmental Sciences Essay

Marine Pollution Causes Effects And Control Environmental Sciences Essay The phrase heavy metals is used here as a general name for metals with densities in excess of 5 g/cm3. About 15 species are of practical concern. Heavy metals may be applied to soils deliberately to correct nutrient deficiencies or to kill pests. Very small amounts are needed to correct deficiencies, and these do not cause pollution. Repeated applications of inorganic pesticides containing heavy metals (for example, in sprays applied to fruit trees) may add amounts to soils large enough to be harmful. In contrast to organic pesticides, heavy metals do not disappear through decomposition but remain in soil indefinitely. Additional sources of soil contamination by heavy metals are industrial and traffic exhausts, flooding of land by contaminated waters, sewage sludge applied to land, and disposal of other refuse. Heavy metals participate in several kinds of reactions in soils, and these affect their concentrations and solubility. The metal ions tend to be bonded to soil constituents through cation exchange; this may amount to substantial quantities even though concentrations in the soil solution are usually low. Some soil constituents seem to have specific affinities for heavy metal ions, resulting in their preferential adsorption over more abundant cations. The concentrations of heavy metals in the soil solution are also affected by equilibria with hydroxyl, carbonate, and phosphate ions. Precipitation of heavy metals by these anions can limit concentrations even though fairly large amounts are added to soil. On the other hand, some heavy metal ions are strongly chelated by organic substances of low molecular weight, thereby altering their adsorption behavior and permitting rather high concentrations in the soil solution. The actual concentration in a soil is thus a function of reactions of heavy metals with a variety of soil constituents. Cadmium is considered as one of the most hazardous of the heavy metals because of its presumed effect on the development of vascular disease. Amounts of cadmium in soils are normally below 1 ppm, but values as high as 1700 ppm have been reported for surface samples collected near zinc-ore smelters. Cadmium is usually associated with zinc in nature, and the geochemical relationship between the two leads to their common occurrence with Zn/Cd ratios near 900. Cadmium is easily taken up by most plants. Some are quite sensitive to excess cadmium, and others are not. (ii) Chromium (Cr) This metal is a major component of the wastes of the plating industry. Cr is toxic for plant growth only at high concentrations. Chromium mobility within plants is extremely low. Soil pollution by chromium is seldom a problem because it is taken up by plants as chromate, a form that hardly occurs at prevailing pH values and redox potentials. (iii) Cobalt (Co) This can be highly toxic to plants. Most plant species cannot tolerate concentrations of cobalt exceeding 0.1 ppm. Usually cobalt contents of soil do not exceed 10 ppm. Preferential cobalt adsorption on soil constituents and fixation in clay mineral lattices might add to the problem. (iv) Copper (Cu) Copper is toxic to most plants at concentrations exceeding 0.1 ppm. Its concentration in drinking water for human consumption is considered safe when not exceeding 1.0 ppm. Concentrations above 20 ppm in feed and forage are toxic to sheep. Normal copper contents of soils are around 20 ppm. Mobility and displacement of copper in soils are low because of its strong bonding with organic matter and clay minerals. (v) Lead (Pb) This may accumulate in soils along roads from traffic exhausts and in the vicinities of lead-zinc smelters. Roadside concentrations as high as 2400 ppm have been reported. While (excessive) intake of lead by humans and animals is considered a serious health hazard, the primary pathway of such intakes is probably via surface contamination of crops and grasses (eaten by grazing animals) rather than via plant uptake. The mobility of lead in soil and plants tends to be low though in some cases considerable uptake by plants has been observed. Normal lead levels in plants range from 0.5-3 ppm. With respect to plant growth, lead toxicity levels appear to differ considerably for different plant species. (vi) Mercury (Hg) Extensive mercury poisoning was first reported at Minamata, Japan, in 1953. As a result of the strong interactions between mercury compounds and soil constituents, displacement of mercury in forms other than vapor is usually very low. Methylation of mercury, possibly occurring in nature under restricted conditions, constitutes one of the most serious hazards related to this element, because in this form mercury will accumulate easily in food chains. Because of this hazard, the use of alkylmercury fungicides for seed dressings has been banned in many countries. (vii) Molybdenum (Mo) This element is best known for its deficiency in certain soils. Under normal conditions molybdenum predominates in anionic form (molybdate), subject to adsorption by iron oxides and hydroxides much like phosphate. While normal molybdenum content in plants is around 0.1 ppm, toxicity symptoms have been observed at levels above 200-300 ppm (dry matter). (viii) Nickel (Ni) This element tends to be highly toxic to plants. As it is easily taken up by plants when present in soils, care must be exercised in disposal of waste containing nickel. Total nickel contents in soils range from 5-500 ppm, with 100 ppm as a rough mean value. The concentration in the soil solution is usually around 0.005-0.05 ppm, and contents in healthy plants do not exceed 1 ppm (dry matter). (ix) Zinc (Zn) The use of this element in galvanized iron is widespread. Zinc commonly occurs in soils at levels of 10-300 ppm, with 30-50 ppm as a rough average range. Sewage sludges may have very high zinc contents, and the possible accumulation of zinc in soil after disposal of such wastes deserves attention. In plants, zinc will become toxic at levels exceeding about 400 ppm (dry matter), where it probably interferes with the uptake of other essential elements. In soil, zinc appears to be rather mobile. Wastes and soil pollution The large amount of waste produced every day in towns and cities and other human settlements end up in soil. The most common kinds of wastes can be classified into four types: agricultural, industrial, municipal, and nuclear (Table 5.13). Table 5.13. Wastes and Soil Pollution Sources Effects Agriculture (i) accumulation of animal manures (ii) excessive input of chemical fertilizers (iii) illicit dumping of tainted crops on land Mining and Quarrying (i) using of explosives to blow up mines (ii) using of machineries which emit toxic byproducts and leaks to the ground Sewage sludge Improper sanitation system causes sludge to leak at surrounding soil Household (i) improper waste disposal system causes waste accumulation (ii) improper sanitation system Dredged spoils Method of dredging at fertile land causes soil infertility, leaving the soil more prone to external pollution Demolition and construction Nonbiodegradable rubbles or debris which undergo chemical reactions and increase soil toxicity Industrial Poisonous/toxic gases which are not filtered or neutralized Control of Soil pollution The following general methods of controlling soil pollution are in use. Effluents should be properly treated before discharging them on to soil. Solid wastes should be properly collected and disposed of by appropriate method. From the wastes, recovery of useful products should be done. Microbial degradation of biodegradable substances reduces soil pollution. 5.5 Marine Pollution: Causes, Effects and Control The sea, which covers around 70 per cent of the earths surface, is home to millions of fish, crustaceans, mammals, microorganisms, and plants. It is a vital source of food for both animals and people. Thousands of birds rely on the sea for their daily food supplies. Fishermen throughout the world catch over 90 million tons of fish every year, and in many developing countries, fish is the principal source of protein.   People also depend on the sea for many of their medicines. Marine animals and plants contain many chemicals that can be used to cure human ailments: an estimated 500 sea species yield chemicals that could help treat cancer.   But the oceans now are in a very bad shape. People have treated the sea as a dumping ground for thousands of years, offloading rubbish, sewage, and more recently industrial waste. Marine pollution frequently originates on land, entering the sea via rivers and pipelines. This means that coastal waters are dirtier than the open seas, with estuaries and harbours being especially badly affected. Additional pollution is actually created at sea by activities such as dredging, drilling for oil and minerals, and shipping.   Marine Pollution   For close to thirty years, most academics studying the phenomena of marine pollution have adhered to a definition developed by a UN body, the Group of Experts on the Scientific Aspects of Marine Pollution (GESAMP), who define it as Introduction by man, directly or indirectly, of substances or energy into the marine environment (including estuaries) resulting in such deleterious effects as harm to living resources, hazard to human health, hindrance to marine activities including fishing, impairment of quality for use of sea-water, and reduction of amenities.   The definition has two important aspects:   First, it is action oriented. Marine pollution results from human activity. Thus, earthquakes or volcanic eruptions in the ocean floor and subsequent damage or change to the ocean ecosystems is not considered as pollution.   Second, the definition is amenable to measurement. Marine pollution is harmful, and its danger can be identified in a variety of ways. For example, it is easy to see the deleterious effects that oil spills have on the sea birds and mammals that happen to run into them. Scientists likewise can readily identify various toxic substances found in the marine environment, measure their quantities, and provide estimates of their potential danger for the health of both marine life and humans.   The important sources of marine pollution are shown in Fig. 5.4. Toxics Toxic waste is the most harmful form of pollution to marine creatures.   Once a form of toxic waste affects an organism, it can be quickly passed along the food chain and might eventually end up in seafood, causing various problems. Toxic wastes arrive from the leakage of landfills, dumps, mines and farms.   Sewage and industrial wastes introduce chemical pollutants like DDT. Farm chemicals (insecticides and herbicides) along with heavy metals (e.g. mercury and zinc) can have disastrous effect on marine life.   Mercury the most dangerous toxic  element Top priority is usually given to control the pollutant that poses a threat to human health, the most serious being mercury.   Major sources of mercury include rivers, marine outfalls and direct dumping of chemical waste. Natural inputs like the weathering of mercury-bearing rocks, volcanic gases also contribute to mercury in the ocean.   Dissolved mercury in the sea is adsorbed onto particulate matter and also forms stable complexes with organic compounds occurring in the sea. Inorganic mercury can be easily accumulated by living organisms. Fig. 5.4. Sources of marine pollution. A classic example of mercury poisoning happened in Minamata, a small Japanese coastal town dependent on fishing for a livelihood. In 1952, a nearby factory producing vinyl chloride and acetaldehyde using mercuric sulphate as a catalyst dumped its wastes in Minamata bay. Typically 300-1000 g of mercury is lost for each ton of acetaldehyde produced, 5% of which is in the form of methyl mercury. Mercuric chloride when used as a catalyst produces 1 g of methyl mercury per ton of product. Accumulated contamination was as high as 200 ppm mercury at the factory outfall.   The effects began with the death of a large number of fish in the early 1950s. This affected birds, cats, pigs, and humans.  Birds lost coordination to fly.   Cats were seen running in circles and foaming at the mouth.   Local residents called these occurrences the disease of the dancing cats.   Later, the disease was termed Minamata Disease when humans began to have symptoms of methyl mercury poisoning.   Other Toxic Materials   Toxic materials are substances derived from industrial, agricultural, household cleaning, gardening and automotive products. They do not always kill wildlife, but they can threaten inland and coastal waters. Examples of toxic materials include:   Dioxins come from bleaching paper, incineration of solid wastes containing PVC and other materials, and the process of making herbicides. Dioxins and related compounds degrade slowly and are toxic to marine life. They cause genetic chromosomal aberrations in marine life and are suspected of causing cancer in humans.   PCBs are used in the making electrical equipments and hydraulic fluids. Developmental problems in children and reproductive problems in some other animals have been linked to PCBs. Slowly degrading PCBs accumulate as they pass along the ocean food web. PAHs come from oil spills, road runoff, and burning wood and coal.   Marine life and people suffer ill effects from PAHs. PAHs cause genetic and chromosomal problems in fish and most marine organisms.   Sewage and fertilizers   The discharge of sewage can cause public health problems either from contact with polluted waters or from consumption of contaminated fish or shellfish.   The discharge of untreated sewage effluents also produces long-term adverse impacts on the ecology of critical coastal ecosystems in localized areas due to the contribution of nutrients and other pollutants. Pollution due to inadequate sewage disposal causes nutrient enrichment around population centers, and high nutrient levels and even eutrophication near treatment facilities and sewage outfalls.   Around the world, untreated sewage flows into coastal waters, carrying organic waste and nutrients that can lead to oxygen depletion, as well as disease-causing bacteria and parasites that require closing beaches and shellfish beds.  The inadequate number of sewage treatment plants in operation, combined with poor operating conditions of available treatment plants, and the disposal practices of discharging mostly untreated wastewater are likely to have an adverse effect on the ocean.   Oil   The sites most vulnerable for accidents are areas where tankers and barges move through restricted channels and in the vicinity of ports.   In spite of regulations established, tankers and barges do not always use port facilities for the disposal of bilge and tank washing and wastes, and a significant amount of oil, which exceeds that from accidental oil spills, is discharged into the coastal areas. The impact of oil pollution on the ecology of coastal and marine ecosystems is particularly destructive following massive oil spills caused by maritime accidents.   However, gas exchange between the water and the atmosphere is decreased by oil remaining on the surface of the water, with the possible result of oxygen depletion in enclosed bays where surface wave action is minimal. Coral death results from smothering when submerged oil directly adheres to coral surfaces and oil slicks affect sea birds and other marine animals. In addition, tar accumulation on beaches reduces tourism potential of coastal areas.   Mining and Dredging   Mining affects the marine ecosystem and the habitat. Mining can erode beaches, degrade water quality, and spoil coastal habitats. Mining coral to process for lime can remove the habitat of local marine species and weakens coastal storm defense. Mined or dredged areas take a very long time to recover. Because of this, strict regulations govern the dredging of the ocean floor   Synthetic Organic Chemicals   Many different synthetic organic chemicals enter the ocean and become incorporated into organisms. Ingestion of small amounts can cause illness or death.   Halogenated hydrocarbons are a class of synthetic hydrocarbon compounds that contain chlorine, bromine, or iodine are used in pesticides, flame retardants, industrial solvents, and cleaning fluids.   The level of synthetic organic chemicals in seawater is usually very low, but some organisms can concentrate these toxic substances in their flesh at higher levels in the food chain. That is an example of biological amplification.   Marine debris   More garbage such as plastic bags, rope, helium balloons, and stray fishing gear, build up in the oceans every year. Synthetic materials stay in the environment for years, killing or injuring ocean species, like whales and turtles, which mistake litter for food or get entangled in it. Ghost fishing by lost nets not only kills innocent ocean creatures but also reduces fishers catches.   Plastic is not biodegradable and therefore affects the oceans for long periods of time. Sea turtles mistake plastic bags for jellyfish and die from internal blockages. Seals and sea lions starve after being muzzled by six-pack rings or entangled by nets.   Effects of Marine Pollution on Living Marine Resources Tens of thousands of chemicals are used to meet societys technological and economic needs. Marine pollution is not only attributed to oil and chemical spills, but much of the debris and toxic substances affecting marine animals, in actual fact, originate on land. Pesticides, plastic bags, balloons, cigarette butts, motor oil, fishing line, find their way into local waterways either though direct dumping, through storm drains (whatever is left on streets, parking lots, can be washed into storm drains which lead directly to local waters), or through sanitary sewers, affecting living marine resources.   The time taken by a few common types of litter to biodegrade is given in Table 5.14. Two basic ways by which chemical contaminants can affect living marine resources are:   By directly affecting the exposed organisms own health and survival, and   By contaminating those resources that other species, including humans, may consume.   Researchers have been studying this dual impact of contaminants using a variety of marine organisms ranging from bottom-dwelling invertebrates and fish to species such as salmon and marine mammals. These biological effects include:   Diseases such as liver lesions in bottom fish, Decreased reproductive success in bottom fish, Impaired immune competence in anadromous fish, and   Growth impairment in invertebrates.   Marine pollution can have serious economic impact on coastal activities and on those who exploit the resources of the sea. In most cases such damage is caused primarily by the physical properties of these pollutants creating nuisance and hazardous conditions. Table 5.14.

Hotel and restaurant owners and others who gain their livelihood from the tourist trade can also be affected.   Oil and chemical spills can adversely affect industries that rely on a clean supply of seawater for their normal operations. If substantial quantities of floating or sub-surface pollutants are drawn through intakes, contamination of the condenser tubes may result, requiring a reduction in output or total shutdown. Simply, the effects of marine pollution are caused by either the physical nature of the pollutants themselves (physical contamination and smothering) or by their chemical components (toxic effects and accumulation leading to tainting). Marine life may also be affected by clean-up operations or indirectly through physical damage to the habitats in which plants and animals live. The main threat posed to living resources by the persistent residues of spilled oils and water-in-oil emulsions (mousse) is one of physical smothering. The animals and plants most at risk are those that could come into contact with a contaminated sea surface:   Marine mammals and reptiles. Birds that feed by diving or form flocks on the sea. Marine life on shorelines and Animals and plants in Mari culture facilities.   Subsequently the inability of individual marine organisms to reproduce, grow, feed or perform other functions can be caused by prolonged exposure to pollutants, if not eventual death. Sedentary animals in shallow waters such as oysters, mussels and clams that routinely filter large volumes of seawater to extract food are especially likely to accumulate oil components and harmful chemicals, poisoning consumers.   In addition to that, birds, whales and other marine creatures often mistake cigarette butts (which find their way into the waters) for food. The butts contain small plastic pieces that can interfere with the digestion of food, casing marine life to starve. Monofilament fishing line can be lethal to seals, sea lions, fish and other animals. Many marine species, including seals, herring, gulls, sharks, and shellfish have died or suffered injuries from plastic bags, nets and monofilament fishing lines.   Impacts on specific marine habitats The impact that marine pollution can have on selected marine habitats are given below. Within each habitat a wide range of environmental conditions prevail and often there is no clear division between one habitat and another.   In coastal areas some marine mammals and reptiles, such as turtles, may be particularly vulnerable to adverse effects from contamination because of their need to surface to breathe and to leave the water to breed.   The impact of oil on shorelines may be particularly great where large areas of rocks, sand and mud are uncovered at low tide.   The amenity value of beaches and rocky shores may require the use of rapid, effective clean-up techniques, which may not be compatible with the plants and animals.   In tropical regions, mangrove trees have complex breathing roots above the surface of the organically rich and oxygen-depleted mud in which they live. Oil may block the openings of the air breathing roots of mangroves or interfere with the trees salt balance, causing leaves to drop and the tress to die. Fresh oil entering nearby animal burrows can damage the root systems and the effect may persist for some time inhibiting decolonization by mangrove seedlings.   Living corals grow on the calcified remains of dead coral colonies that form overhangs, crevices and other irregularities inhabited by a rich variety of fish and other animals. If the living coral is destroyed the reef itself may be subject to wave erosion.   Birds which congregate in large numbers on the sea or shorelines to breed, feed or molt are particularly vulnerable to oil pollution. Although oil ingested by birds during preening may be lethal, the most common cause of death is from drowning, starvation and loss of body heat when their body surfaces are coated with oil.   Impact on fisheries and Mariculture   The pollutants in the waters, especially in the case of oil spills can also damage boats and gears used for catching or cultivating marine species. Floating equipment and fixed traps extending above the sea surface are more likely to become contaminated by floating oil whereas submerged nets, pots, lines and bottom trawls are usually well protected, provided they are not lifted through an oily sea surface.   An oil or chemical spill can also cause loss of market confidence since the public may be unwilling to purchase marine products from the region irrespective of whether the seafood is actually tainted. Bans on the fishing and harvesting of marine products may be imposed following a spill, both to maintain market confidence and to protect fishing gear and catches from contamination.   5.6 Noise Pollution Noise usually means unwanted sound of appreciable intensity which goes on for a length of time (seconds to hours) that irritates people. The noise may emanate from factories, offices and market place, roads (traffic-related), running and shuttling of trains, landing and take-offs of aircrafts at airports, use of loudspeakers in meetings, rallies, celebrations, etc. When the quality and the intensity of the noise is practically constant (varying less than  ±5 dBA) over an appreciable time (seconds or longer), it is often called steady-state noise. The first reaction to any form of unwanted sound is annoyance, followed by irritation, restlessness and extreme reaction. Since noise travels through air, all forms of noise are considered as polluting air and noise is considered as an air pollutant. Sound is defined as a pressure variation that the human ear can detect. Just like dominoes, a wave motion is set off when an element sets the nearest particle of air into motion. This motion gradually spreads to adjacent air particles further away from the source. Depending on the medium, sound propagates at different speeds. In air, sound propagates at a speed of approximately 340 m/s. In liquids and solids, the propagation velocity is greater, 1500 m/s in water and 5000 m/s in steel. Compared to the static air pressure (105 Pa), the audible sound pressure variations are very small ranging from about 20  µPa (20 ÃÆ'- 10-6 Pa) to 100 Pa. The sound pressure level of 20  µPa corresponds to the average persons threshold of hearing. A sound pressure of approximately 100 Pa is so loud that it causes pain and is therefore called the threshold of pain. The ratio between these two extremes is more than a million to one. Sound pressure level alone is not a reliable indicator of loudness. The frequency or pitch of a sound also has a substantial effect on how humans will respond. While the intensity (energy per unit area) of the sound is a purely physical quantity, the loudness or human response depends on the characteristics of the human ear. A direct application of linear scales (in Pa) to the measurement of sound pressure leads to large and unwieldy numbers. Therefore, the acoustic parameters are conveniently expressed as a logarithmic ratio of the measured value to a reference value. This logarithmic ratio is called a decibel or dB. Using dB, the large numbers are converted into a manageable scale from 0 dB at the threshold of hearing (20  µPa) to 130 dB at the threshold of pain (~100 Pa). Some examples of common noise and their decibel levels are given in Table 5.16. The decibel scale is open-ended. 0 dB or dBA should not be construed as the absence of sound. Instead, it is the generally accepted threshold of best human hearing. Sound pressure levels in negative decibel ranges are inaudible to humans. On the other extreme, the decibel scale can go much higher. For example, gun shots, explosions, and rocket engines can reach 140 dBA or higher at close range. Noise levels approaching 140 dBA are nearing the threshold of pain. Higher levels can inflict physical damage on such things as structural members of air and spacecraft and related parts. Table 5.16.

Basically, there are two different instruments to measure noise exposures: the sound level meter and the dosimeter. A sound level meter is a device that measures the intensity of sound at a given moment. Since sound level meters provide a measure of sound intensity at only one point in time, it is generally necessary to take a number of measurements at different times during the day to estimate noise exposure over a workday. This measurement method is generally referred to as area noise monitoring. A dosimeter is like a sound level meter except that it stores sound level measurements and integrates these measurements over time, providing an average noise exposure reading for a given period of time such as an 8-hour workday. The dosimeter measures noise levels in those locations in which a person works or spends long intervals of time. Such procedures are generally referred to as personal noise monitoring. Human hearing is limited not only to the range of audible frequencies, but also in the way it perceives the sound pressure level in that range. In general, the healthy human ear is most sensitive to sounds between 1,000 Hz 5000 Hz, and perceives both higher and lower frequency sounds of the same magnitude with less intensity. In order to approximate the frequency response of the human ear, a series of sound pressure level adjustments is usually applied to the sound measured by a sound level meter. The adjustments, or weighting network, are frequency dependent. The A-scale approximates the frequency response of the average young ear when listening to most ordinary everyday sounds. When people make relative judgments of the loudness or annoyance of a sound, their judgments correlate well with the A-scale sound levels of those sounds. There are other weighting networks that have been devised to address high noise levels or other special problems (B-scale, C-scale, D-scale etc.) but these scales are rarely, if ever, used in conjunction with highway traffic noise. Noise levels are generated in the A-scale as dBA. In environmental noise studies, A-weighted sound pressure levels are commonly referred to as noise levels. Sources of noise Various sources of noise (Table 5.17) are industry, road traffic, rail traffic, air traffic, construction and public works, indoor sources (air conditioners, air coolers, radio, television and other home appliances), etc. In Indian conditions, indiscriminate use of public address system and diesel generator (DG) sets, has given a new dimension to the noise pollution problem. Noise in Industrial Areas. Mechanized industry creates serious noise problems, su

Protecting Women from Domestic Violence Essay -- Abuse Violence Essays

â€Å"Domestic violence is the most ubiquitous constant in women’s lives around the world. There is virtually no place where it is not a significant problem, and women of no race, class, or age are exempt from its reach† -Joni Seager Abstract: Domestic violence against women is a social problem that occurs in nearly every corner of the world. Recently, some states have begun to recognize that women must be protected from abuse by family members and intimates. While policies and practices designed to protect women have emerged in a number of countries, many lag behind on the issue. This paper will examine the causal factors behind the variation in protection for women. The literature on women and politics suggests that women’s representation may increase the level of protection against domestic violence because female legislators are more likely to put women’s issues on the agenda and make policy choices that benefit their sex. Alternatively, the culture of a state may determine whether the society supports rights for women, including protection from domestic violence. A variety of statistics indicating women’s representation and culture were gathered for analysis. Using bi variate cor relation and multiple regression, the theories were tested against each other in an attempt to determine the cause of variation in levels of protection. The findings suggest that both women’s representation and culture are significantly correlated to level of protection. Because the number of women in elected office influences protection to a greater extent than culture, improving women’s representation appears to be an important factor in fighting the domestic violence problem.

freudian psychology :: essays research papers fc

Annotated Bibliography Personality Theories. Ed. Dr. C. George Boeree. 1997. Shippensburg University. .   Ã‚  Ã‚  Ã‚  Ã‚  This site was very good in giving me insight into the basics of psychology. I looked at the Freud category mostly because he is a big name and his theories were pretty easy to understand. Applying it to my paper, I used his ideas and descriptions of the id, ego and superego in an attempt to correctly justify the main character’s actions and reasons for doing what he did. Freud and Dreams. Freud Museum in London. 1998. . This was one of the nicer pages I visited to find info about dreams and the significance of them. I really liked the way the site explained Freud’s theories behind what dreams are and what they represent. I used a lot of this in the dreams I tried to recreate in the story attempting to make them seem as realistic as possible. Rowell, Maria Helena. The Freud Page. 1998. . This was another great place for information on Freud’s theories. I learned a lot about the conscious, preconscious, and unconscious minds. From here, I tried to figure out ways of masking which mind was in control during the story with the shifting dreamscapes and rapid changes in consciousness. Jung, Carl G. Anatomy of a Dream. 1997. . In an attempt to get another opinion on what dreams are and how they function, I looked to this page. I found some very useful information about what causes dreams and what manifestations result in the conscious mind from them. I used this to try and tie his dreams to his everyday happenings. Also, I tried to relate this info to how his dreams were related to what was happening to him while conscious.

Bhagavad Gita Critique

Well I would first like to start off by saying that after I let go of my personal beliefs for a moment, and actually let myself be open to the ideas of the Bhagavad-Gita I rather enjoyed it and I feel like I actually can see how the â€Å"ways of life† (for loss of a better term) that are expressed in this make a lot of sense. I can actually sit and think about what kind of people today would possibly be categorized as Tamasic, Rajasic and Sattvic. I also can see some very similar concepts in the book that follow modern Christian beliefs and values which made it a lot more interesting. For example from the time I wake up to the time I go to bed I thank God and Jesus for the blessings and positive moments in my life. I pray throughout the day when things are good or bad. I also try to live a â€Å"good Christian† life as well as just trying to be a good person. I guess my ideas of a good person stem from my influences and morals, as well as my new found belief in God and Jesus. I try to worship, pray and give thanks everyday. I try to read my bible as often as I can, seeing I’m so busy all the time it has been hard to even find the time to pick it up, but I do try to think before I act, speak and think. I think â€Å"what would Jesus and God and all my loved ones think of the thing I am about to do† or â€Å"what would Jesus say if I completed that not nice thought about that person†. Seeing how I believe every one of us is a child of Gods and that God knows everything we do, say, think and so on; I try to keep my life to a pure as I can standard. I think about all that I have been given and the least I can do is try my best to be my best for Jesus, God and all that I am connected to in this lifetime. This brings me to my topic, spiritual beliefs. There are so many different types of religion. Catholicism, Hinduism, Christianity, etc. They all have various ways of â€Å"being† when it comes to being a member of the church or religion. No two parties are alike that is why no two peoples beliefs are the same completely. Yet when you read the Bhagavad-Gita it puts it so simple. Do your life this way you are worthy of finally passing on into the next life for eternity. Do your life that way you come back and suffer a circle of never ending lives. Try but not quit there you come back to life but in a higher level of caste so you can start off close to where you left off. It is all pretty simple. In the book it is basically Arjuna asking guidance from Krishna. At first it is whether he should fight or not fight, then it turns into a â€Å"how do I live my life for you in your way† topic. Krishna basically starts out very slow in explaining that all life is connected and is stemmed from his existence. That life is here in the body form but continues into the spirit world with him, and that life is a never ending circle until you reach the highest point of understanding and are worthy of being with him in the spirit world forever. That when you realize that life never truly ends, that it is just the body that dies you cannot feel sad for such things as fighting wars and killing men. Then he explains such things as the importance of ceremony and living a pure life, then about the Brahmas and literally tells him the secrets of life. Krishna reveals his true great form to Arjuna and covers all the possible topics you could think of when it comes to being Hindu. The story is so filling that you literally wonder how it could possibly have an end to it. The main point I got from the book was that it is important to live your life according to first what you think is right and then second to what you believe Krishna and the other Gods (which are Krishna and they are him) say is the way to live. In the book it speaks of how to perform ceremonies and the importance of not just performing them but to perform them with heart. You are to serve good foods and give great offerings to your God. You yourself are to eat good foods and take care of your body for the Gods as well. You are to drink and perform the ceremonies the way the scriptures say and to keep your heart and mind on God (Krishna). Then it sort of ends weird; It says that you are to live your life well and good and pure but that you have to follow the path you think is the right one. And that when you think you have reached that level of true knowledge you are to try to share that with others. So I guess what I got out of it is just that; live your life to the best you think you can. Don’t be a selfish, greedy, rude, etc. person. Don’t have false beliefs even if that means you have none. And to try to give your heart over to the beliefs you do have. If they were the right ones then you win the ultimate prize, eternity with Krishna. If it was the wrong one you just have to keep trying until you get it right. I read this book and I pretty much decided that it is great to help guide you no matter what religion you believe in. Just the base principles and sort of guide it lays out for the individual, so you can clearly see the different ways and the different options is so clear and simple it cant not make sense. And I love the fact that the idea is that everything comes from one God initially even if there are other gods now everything is God and he is everything, even if you are not in god, he is in you. I am so happy I had the opportunity to be exposed to such a great experience. It will stay with me forever.
