Threats to an indigenous culture - Essay Example The SÃ ¡mi culture encompasses various unique activities carried out by the SÃ ¡mi people for many decades. However, this precious culture faces external threats that interfere with the core activities and beliefs carried out by the SÃ ¡mi people. The SÃ ¡mi people rely greatly on natural resources for their livelihood hence making the SÃ ¡mi culture to be associated with nature. According to the Resource Centre for the Rights of Indigenous Peoples, the Sami people were initially categorized depending on the characteristic of the natural environment they occupied (1). This means that different Sami people depended on different natural resources for their livelihood depending on their location. Firstly, the Sami people living in the coast of the Arctic Ocean are categorized as the Sea SÃ ¡mi (Resource Centre for the Rights of Indigenous Peoples 2). Due to the closer location to Arctic Ocean, the livelihood of the Sea SÃ ¡mi mainly depended on resources from the ocean. This means that the main economic activity that was associated with this category was fishing from the ocean. The second category of the SÃ ¡mi people is called the forest SÃ ¡mi. This category of SÃ ¡mi people relied heavily on hunting and gathering as th e source of their livelihood. However, it is worth noting that the SÃ ¡mi people are nomadic and relied heavily in the reindeer in addition to other resources offered by nature. Historical background of the SÃ ¡mi people provides important clues about various activities carried valued in the SÃ ¡mi culture. According to Resource Centre for the Rights of Indigenous Peoples, the SÃ ¡mi people descended from people who inhabited the Northern Fennoscandia after the ice age period (1). This indicates that the SÃ ¡mi people are the original landowners in the arctic region. In addition, the ancestry of the SÃ ¡mi people indicates that they had already adapted to the living conditions in the arctic regions. Resource Centre for the Rights of Indigenous Peoples further

Executive Compensation - How much is too Much Research Paper

Executive Compensation - How much is too Much - Research Paper Example The debate about high executive compensation has been in the spotlight in United States since industrial revolution. However, it was during the great depression that this news and discussion made the headlines. Since then, this debate has always received widespread during all economic recessions. Following the pattern, as the financial crunch and economic recession hit the United States in 2006-07, this debate again reached its peak because the masses started questioning the perceived wide gap between the salaries of an average employee and the executives. Critics of high compensation believe that this is one of prime reasons of increasing inefficiencies, recession, and increasing income inequality in United States. On the other hand, proponents of high compensation believe that these pay levels are a result of market and competitive forces and external forces such as the government, watchdogs and others should have no right to interfere in how much the boards of willing to pay their executives. The thesis statement around which this paper that revolve is that â€Å"executives pay is sky rocketing and there is no rational and logical thought to allow these pay levels to increase further if we want a way out of this recession and prevent future recessions† (Mishra, McConaughy & Gobeli, 2000). ... They compare the pay of CEOs with investment bankers, hedge fund managers, equity investors, lawyers, and others. Since 1990s, there has been steady increase in the salaries of above-mentioned professionals but the pays of CEOs and other executives has not risen with the same percentage. Furthermore, out of the top 0.1 percent people in the United States arranged according to the gross income, only 3 percent of them were CEOs and executives of companies. Furthermore, in the year 2007, â€Å"top 20 hedge fund manager bagged more than three times the pay earned by the salaries of all S&P 500 combined† (Hayes & Schaefer, 2009). Proponents of this school of thought strongly believe that companies will have to take bold steps in order to retain their executives because many smart CEOs have already started shifting to Wall Street to take positions at private equity firms (Hayes & Schaefer, 2009). In order to defend the position of CEOs being overpaid, other experts have gone on to a ccept that executives and specifically, CEOs are overpaid but it is not because of the work that they do but because their job is to inspire people. The reason behind providing CEOs with the fattest checks is to ensure that it keeps other people in the company motivated (Kay & Putten, 2007). Everyone dreams to become a CEO or an executive some day and people dream about the same because they know the compensation levels. People look at executives, their cars, houses, clubs, salaries, benefits, lifestyles and that is what keeps them motivated to stay with a company and put in their best effort into their jobs hoping that within a decade or so, they would also be able to reach that dream position. Economists call this, as

Hereford Plays series Essay Example for Free

Hereford Plays series Essay After the complex events of the scene before, Marco jumps in to try and regain his brothers dignity. This is his family and he cannot let Rodolpho be disgraced like that or be hurt; whether it was just a stagger or not, Eddie was out of order and Marco wont allow it. As Catherine and Rodolpho dance, Marco discusses a friendly challenge: Marco takes a chair and places it in front of Eddie. Eddie has to lift the chair as far up as he can with one hand holding it by the bottom of one leg. As Eddie kneels and grasps the leg he lifts it by an inch whereas when Marco tries it he lifts it all the way above his head. This simple action obviously had a motive behind it: to warn Eddie to lay off his brother but Eddie consciously knows that he wont give up that easily. Marco has shown that Eddie may think hes more of a man than Rodolpho but Marco is more of a man than Eddie; this event has generally shamed Eddie in his home, which is something this character feels very strongly about as the head of the household. The scene needs a sense of oppositon and competition. In order to emphasise what is to be a true test of strength, the onlookers (Rodolpho, Catherine and Beatrice) need to have complete awareness and support of Marcos triumph. In this scene you have to visually compare the failure of Eddie in comparison to the triumph of Marco. While Marco is lifting the chair he is struggling and the tension in his neck, face, arms and especially his facial expression is needed to portray not just victory of lifting the chair but the victory of putting Eddie to shame and gaining some respect for his brother. This scene is a turning point in the story because Eddie now knows that if he wants Rodolpho out of his life hell may have to take even more extreme measures and the battle has turned from not just putting Catherine off of Rodolpho but to get these immigrants out of his house. Its important for its visual impact on the audience because its dramatic actions of a fight for strength and self-dignity turns the whole generalisation of the story from a happy family get-together into a potential crime against his (Eddies) family and the Sicilian community (as quoted from synopsis/pri cis of the book). Its also important because it shows Marcos justified slyness; justified because he has dishonoured Eddie but only in retaliation to Eddie taking advantage of Rodolpho. As soon as Marco said Here and started to lift the chair it is the beginning of Eddies slowly increasing shame and disgrace. The victory celebration should idealistically be a smiled expression (from Marco) as if to imply to Eddie that no-one messes with his brother or else theyll answer to him. As director I would issue the following instructions: Catherine: youre enjoying your dance with Rodolpho and you are nai ve as to what might be going on with Eddie and Marco so keep off guard and treat the situation as though its just a bit of fun between them. Beatrice: you have realised that Eddie feels discomforted at the weak position that he has been put in; however you believed that he deserved it and you are just hoping that Eddie has learned his lesson and will not interfere again. Act supportive at his distress but dont destroy is ride by talking about it too much (as your character would naturally do) Eddie: you have to accept Marcos offer very boldly and confidently as Catherine might be watching and you dont want to back down now. Your facial expression has to show repressed rage at Marco; grind your teeth and be silent to keep your pride, you want everyone else in the room to feel that what has happened doesnt mean or prove anything so get on as though it didnt happen although youre still much aware of the damage that Marco has done Marco: you are proud of what you have accomplished but youre not going to look like a show off; if you win gracefully it will add to Eddies shame which is something you want to do. Your facial expression should say Im triumphant and taking it well In conclusion, Eddie cares about his family and the responsibilities that come with it. He was strict in the upbringing of Catherine and had the utmost respect for his wife. Even though he made a fool of himself and died just for his name (his dignity) we must recognise he had a strong and defiant will or view that was his own and that he fought to uphold, such as his primitive mans view that there must be a law that keeps Catherine from marrying Rodolpho because he is supposedly a homosexual. The bottom line is Eddie should have settled for half meaning he brought Catherine up and now it was time to let her go. So in the end, Eddie dies to keep his pride and his name but doesnt even gain the audiences admiration because his actions were unnecessary. As quoted by E. R. Wood, who wrote the introduction in the Hereford Plays series (1975) publication of A View From The Bridge, To be a tragic hero, you do not have to be in the right; you have to be true to yourself. So Eddie was guilty of destroying the lives of these immigrants and the only honourable way out was to die.

Current Air Quality Trend In Malaysia

Current Air Quality Trend In Malaysia Dimitriou and Christidou (2007) mentions air pollution is one of the most pressing global environmental problems that threaten the wellbeing of living organisms, leading to a loss of biodiversity or disrupting the function of the environment as a system. Air pollution occurs as a consequence of natural processes as well as human activity (anthropogenic). Examples of natural causes of air pollution include volcanic eruptions, forest fires and windblown dust. Anthropogenic air pollution from sources like motor vehicles and industries continues to be a serious harm to human health and welfare is more likely, namely the more densely populated urban areas. The health effects of air pollution have been reported in research studies over the past 30 years. These effects include respiratory diseases such as asthma, cardiovascular diseases, changes in lung function, and death. Colls (1997) reported particles in the atmosphere primary or secondary, solid or liquid. They come into the atmosphere, and leave it again by a wide variety of routes. Particulate matter is characterized by its physical and chemical properties Nader (1975). In addition, particle size and particle composition are characteristic that play a significant role in the assessment of health effect. In response to this information, regulatory agencies with a mandate to protect public health must now consider how to implement monitoring networks that will allow measuring the particulate matter concentration. In recent years, a increasing of number of monitoring system for particulate matter (PM) are available and are wide ranging in type, cost, flexibility and accuracy. According to Kingham et al. (2006), accurate and reliable monitoring of PM aerosol in the respirable size fraction ( In 2001, Chung et al pointed about traditional monitoring networks (Continuous Aerosol Mass Monitor, Integrating Nephelometer, Tapered Element Oscillating Microbalance) for airborne particulate matter. A small number of past studies have evaluated the tapered element oscillating microbalance (TEOM) and a series of manual gravimetric methods (Allen et al., 1997, Ayers, 2004, Cyrys et al., 2001, Hauck et al., 2004, Williams et al., 2000) but fewer still have compared other commercial monitors (Baldauf et al., 2001, Chung et al., 2001, Heal et al., 2000, Monn, 2001, Salter and Parsons, 1999). CURRENT AIR QUALITY TREND IN MALAYSIA There are 52 National Air Quality Monitoring Stations (AQMS) in Malaysia, function to monitor continuously 5 major pollutants, namely Particulate Matter (PM10), Ozone (O3), Sulphur Dioxide (SO2), Nitrogen Dioxide (NO2) and Carbon Monoxide (CO). For the northern region of Malaysia (Perlis, Kedah, Pulau Pinang and Perak), the overall air quality levelwas lies between good to moderate. However, there are curtain places (Tanjung Malim, Alor Star and Sungai Petani) recorded unhealthy level of the day especially in the mid of the day till late afternoon due to high concentration of ground level ozone (O3). In tanjung Malim, one unhealthy day was recorded due to high level of particulate matter (PM10) Air Pollutant Index (API) system were used in reporting the air quality status in Malaysia. The API compute from the monitoring of Ground level Ozone (O3), Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2) and Particulate Matter of less than 10 microns in size (PM10). Air quality status can be categorized in five main level (good, moderate, unhealthy, very unhealthy and hazardous as in Table 1.1. Table 1.1 Malaysia : Air Pollution Index (API) (Malaysia Environmental Quality Report 2011, DoE) API Air Quality Status DoE in Malaysia Environmental Quality Report 2011 highlights the annual average of PM10 was 43m3 , but was slightly increased compared to 2010 (39m3 ). However, for both year (2010 and 2011) value still below the Malaysian Ambient Air Quality Guidelines value (50m3 ). The trend of the annual average levels of PM10 concentration in the ambient air between 1999 and 2011 complied with the Malaysian Ambient Air Quality Guidelines as shown in Figure 1.1 and Figure 1.2 shows the trend based on land use categories (Urban, Sub Urban, Background and Rural). MONITORING METHODS AND INSTRUMENTS The underway monitoring of airborne particulate matter in the ambient atmosphere is mainly for determination of the mass of the particle. The methods used for monitoring of concentration of PM can differ and are very dependent upon the aim of monitoring, sites, monitoring problem and resource that available during monitoring period. Usually, monitoring is to determine the concentration of total suspended particulate (TSP) and suspended particulate matter (SPM) have become outdated with the awareness that PM effects varies depending on sizes of the particle. QUARG (1996) pointed that the latest method of monitoring (gravimetric and direct reading method) are designed to determine the concentration of particle in the different sizes (PM10 and PM2.5). Table 1.2 displays the examples of the instrument for PM10 monitoring and the detection methods. Table 1.2 Examples of instruments used in PM monitoring Instrument Principle of detection Beta Attenuation Monitor (BAM) The beta ray sources used in BAM are 14C. Directly measured the particle based on relationship between beta ray attenuation to particle mass. Depends on the near exponential decrease in the total number of beta particle transmitted through a thin sample as the density increase (William et al., 1993) The gravimetric method that only the mass of particle can be affect the detector not by the size of distribution, physical size, shape or either by chemical composition (Chow et al., 1996) Tapered Element Oscillating Microbalance (TEOM) Tapered hollowed channel will act as a gateway where the particles are collected on a filter. For minimum thermal expansion that occurred at the tapered channel, the sample area is maintained at 50 °C. Thermal expansion may affect the oscillation frequency and might be reduce the total amount of particle bound water. DustTrak 8520 Hands carry instrument and highly portable direct reading monitor. Using light scattering laser to detect the particles. Particles scattered the light which is from laser diode drawn through a constant stream. Liu et al., (2002) mentions the amount of light scatter find out the particles mass concentration. PROBLEM STATEMENT In Malaysia, PM10 monitoring was conducted by Alam Sekitar Malaysia Sdn. Bhd. (ASMA). Md Yusof et al (2010) lists two instruments used for monitoring are high volume sampler (HVS) and beta attenuation monitor (BAM). BAM is the standard instrument used by Department of Environment (DoE) to measure particulate matter in 51 monitoring station in Malaysia. Air quality of these new areas cannot be monitored and observed due to the lack of monitoring stations of air quality. To develop these new monitoring stations, definitely it will be costly and need good maintenances. Additionally, air quality at the rural areas also cannot be monitored. Therefore, a new alternative instrument such as Direct Reading Monitors (DRM) will enable air pollutants to be monitored more comprehensively. Even though DoE has set up their monitoring station, the number of monitoring stations is limited. With the use of simple instruments and cost effective, the air quality in areas without monitoring stations can be monitored and assessed. For this study, direct reading monitor (DRM) was used to monitor PM10 concentration at selected stations. However, PM10 concentration recorded using DRM and BAM was different. This is due to different detection method between both instruments (DRM used laser and BAM used beta ray) and response time for DRM was set to one minutes, while BAM records hourly PM10. In addition, the mobile factor that is owned by DRM is also affecting the reading. Therefore, an appropriate coefficient needed to make sure the reading obtained from the DRM is the same as the reading derived from the BAM. OBJECTIVES The objective of this project is:- To estimate coefficient that relates DRM and BAM by using regression techniques. To investigate the best coefficient based on performance indicator. To determine the influence of meteorology on PM10 concentration. SCOPE OF STUDY In Malaysia, Beta Attenuation Monitor (BAM) is the standard instrument used by DoE to measure particulate matter in 52 monitoring stations. This instrument automatically measures and records hourly particulate mass concentration in ambient air. It uses beta ray attenuation to calculate collected particle mass concentration units of  µg/m ³. For this study, Direct Reading Monitor (DRM) was used to monitor PM10 concentration at Air Quality Monitoring Station (AQMS) conducted by Alam Sekitar Malaysia (ASMA). The station selected for this research is Prai and Seberang Jaya. Both stations are situated in the north part of Peninsular Malaysia. They are many researches comparing the mass concentration results of the BAM and gravimetric methods. Salminen and Karlsson (2003) reported the agreement between PM10 concentration measured by BAM and gravimetric method. PM10 concentration recorded by the DRM was compared with data monitored using BAM provided by DoE. Three method of linear regression was used to investigate the relationship between the DRM and BAM monitoring record which is method of ratio, method of quartile and method of quantile. Performance indicators were used to evaluate the goodness of fit for the ratio,quartile and quantile method to determine which method is the best.

CHAPTER 2 LITERATURE REVIEW 2.1 INTRODUCTION Sherman (2003) defined air pollution as the presence of undesirable levels of physical or chemical impurities. Many organization such as the World Health Organization (WHO, 1999) recognized particulate matter (PM), carbon monoxide (CO), nitrogen dioxide (NO2), ozone(O3), lead (Pb) and sulfur dioxide (SO2), as classical pollutants presenting a hazard to sensitive populations. Air pollution now becomes an increasing source of environmental degradation in the developing nations of East Asia (Alles, 2009). The air pollution in Malaysia has not reached a critical level as in other metropolitan areas in Asia, like Jakarta or Manila. (Malaysian German Technical Cooperation, 2000). However; even outside extreme haze periods, pollution levels increased despite tight regulations and this is added by the increase in the number of vehicle, distance travelled and growth in industrial production. Air quality in Malaysia is a major concern as the nation forged ahead to become an industrialized nation by the year 2020. The Malaysian Air Pollution Index (API) is obtained from the measurement of PM10 and several toxic gases such as SO2, CO, NO2, and O3. The air quality status in Malaysia is determined accordingly to API which indicates the level of pollution in the atmosphere. The API system of Malaysia closely follows the Pollutant Standard Index (PSI) system of the United States of America. According to Department of Environment, based on the Air Pollutant Index (API), the overall air quality for Malaysia in 2010 was between good to moderate levels most of the time. The overall number of good air quality days increased in 2010 (63 percent of the time) compared to that in 2009 (56 percent of the time) while remaining 36 percent at moderate level and one percent at unhealthy level. However, peatland fires resulting in transboundary air pollution that occurred in the Southern Asean region in the month of October resulted in a short spell of haze episode in the southern part of Peninsular Malaysia (DoE, 2009 DoE, 2010) DoE also reported that the overall air quality of the northern region of the West Coast of Peninsular Malaysia (Perlis, Kedah, Pulau Pinang and Perak), was between good to moderate most of the time. However, Tanjung Malim and Tasek recorded four unhealthy days and one unhealthy day, respectively. The pollutants of concerned were ground level Ozone (O3) and PM10. 2.2 AIR QUALITY MONITORING IN MALAYSIA In order to ascertain the quality of the environment in Malaysia, the Department of Environment (DoE) regularly monitor the air quality. The air quality monitoring, which involves measurements of total suspended particulates, atmospheric lead and dust fallout, are conducted at 52 monitoring stations (Figure 2.1 and 2.2) categorised as industrial, urban and sub urban areas (DoE, 2010). In addition to the 52 stations in the National Continuous Air Quality Monitoring Network, manual air quality monitoring stations using High Volume Samplers were also established at 14 different sites for measuring total suspended particulates, particulate matter (PM10) and heavy metals such as lead. A continuous automatic monitor which gives instantaneous measurements of gaseous pollutants such as CO, SO2, oxides of nitrogen and ozone, as well as suspended particulate matter and total hydrocarbon used as the monitoring equipments by the DoE to assess air quality (Abdullah, 1995). The air quality status is reported in terms of Air Pollutant Index (API). The air pollutants used in computing the API are ground level ozone (O3), carbon monoxide (CO), nitrogen dioxide (NO2), sulphur dioxide (SO2) and particulate matter of less than 10 microns in size (PM10). The API is categorized as good, moderate, unhealthy, very unhealthy and hazardous. 2.3 SOURCERS OF PM10 The US EPA defines particulate matter (PM) as a mixture of solid particles and liquid droplets found in the air. PM can be in sizes or colors large or dark enough to be observed or it can be so small that an electron microscope is required to distinguish it. According to Fierro (2000), coarse particles (PM10) have an aerodynamic diameter between 2.5 µm and 10 µm. They are formed by mechanical disruption (e.g. crushing, grinding, abrasion of surfaces), evaporation of sprays, and suspension of dust. PM10 particles are small enough to be inhaled and accumulate in the respiratory system (Colls, 1997). Particulate matter can come from many sources. Generally, any activity which involves burning of materials or any dust generating activities are sources of PM. Some sources are natural, such as volcanoes and water mist (Bates, 1995). PM is introduced to the air through both natural and human causes (Harrisonu Yin, 2000). PM from specific sources typically follow short term and long term (seasonal) trends (Yatin et al. 2000). For example, space heating generates more combustion related PM emissions during the cold seasons while, at the same time, snow cover can inhibit PM emissions from the soil. Quality of Urban Air Review Group (1996), published the report in which they describe that primary particles are those directly emitted to the atmosphere from sources such as road traffic, coal burning, industry, windblown soil and dust and sea spray. On the other hand, secondary particles are particles formed within the atmosphere by chemical reaction or condensation of gases, and the major contributors are sulphate and nitrate salts formed from the oxidation of sulphur dioxide and nitrogen oxides respectively. The primary sources of PM in Malaysia, are motor vehicles diesel trucks, industrial emissions, agricultural, slash and yard waste burning, and even exhaust from lawn mowers and boats (Department of Environment, Malaysia, 2010). PM concentrations tend to be especially high in area with greater population density, nearby industries or agriculture, or where local topography or weather conditions contribute to air stagnation. 2.3.1 Traffic Vehicular particle emissions are the result of a great many processes, an example combustion products from fuel and oil, wear products from brake linings, tyres, bearings, car body and road material, and the resuspension of road and soil dust (Laschober et al. 2004). Traffic is an effective source of both fine and coarse mode primary particles, condensable organic gases, and a major source of nitrogen oxides that then form secondary nitrate aerosols. Particles of condensed carbonaceous material are emitted mainly by diesel vehicles and poorly maintained petrol vehicles (Vardoulakis et al. 2003). Diesel exhaust particles have been shown to display a multimodal size distribution (Kerminen et al. 1997) and are mainly carbonaceous agglomerates below 100 nm in diameter, whereas particles emitted by gasoline vehicles are also mainly carbonaceous agglomerates but considerably smaller, ranging from 10 to 80 nm (Morawska and Zhang 2002). Particulate matter originating from traffic can be pres ent at elevated concentrations especially during high traffic density and poor dispersion conditions, e.g. in street canyons, which can lead to high human exposures to traffic-related pollutants (Vardoulakis et al. 2003). Identification of traffic related particulate matter in source apportionment studies has become difficult due to phasing out of Pb as an additive to gasoline. Elements that have often been associated with vehicular emissions include Cu, Zn, Pb, Br, Fe, Ca and Ba (Huang et al. 1994, Cadle et al. 1997, Kemp 2002, Morawska and Zhang 2002, Sternbeck et al., 2002). Emissions of many metallic elements from vehicular sources are mainly due to non exhaust emissions, examples from the wearing of tyres, brakes and other parts of vehicles (Sternbeck et al. 2002, Adachi and Tainosho 2004, Laschober et al. 2004, Lough et al. 2005). In addition to road traffic, emissions from the main and auxiliary engines of ships can be a significant source of particulate matter and associated elements such as V and Ni (Lyyrà ¤nen et al. 1999) at certain locations (Ohlstrà ¶m et al. 2000, Colvile et al. 2001, Isakson et al. 2001). 2.3.2 Stationary sources The most significant stationary combustion sources include energy production facilities such as municipal power plants, waste incineration, and residential combustion. Several industrial processes, such as iron and steel production, also involve combustion of fossil fuels or biomass for generating power and heat needed for the process. Most of these sources are considered point sources, although smaller and more widespread sources such as residential combustion could also be considered as an area source. Physical and chemical characteristics of the particles emitted from these source categories depends on the combustion process itself, and the type of fuel burnt (solid, liquid, or gas). Combustion processes and properties of particulate matter emitted from these sources have been comprehensively reviewed by Morawska and Zhang (2002). The major industrial processes include factories processing metals and chemicals, materials handling, construction and mining. Particulate matter from t hese sources are partly released as fugitive emissions, which are not collected and released in a controlled manner, but emitted from a variety of points and areas connected to a process (Seinfeld and Pandis 1998). Chemical and physical properties of fugitive emissions depend on the processes by which they are emitted. Since the bulk of most trace metals are nowadays emitted from industrial processes, their concentrations are spatially heterogeneous and subsequently, their measurement is quite sensitive in terms of location; however, the reported concentrations of trace metals in major cities demonstrate rather similar levels of trace metals (Harrison and Yin 2000). PM10 CHARACTERISTIC. PM is characterized by its physical, chemical and optical properties. The quality of air that we breathe in every second determine by the amount of particulate matter in it. These particulate matters measure by their particles size. Those with the particles size less than 10 micron (PM10) is used to monitor the air quality which in turn is related to the health problems of the workers or public at large (Alias et al., 2007). The most important characteristic of particulate matter (PM) is the particle size. This property has the greatest impact on the behavior of particulate matter in control equipment, the atmosphere, and the respiratory tract. Particles of importance in air pollution control span a broad size range from extremely small (0.01 micrometer) to more than 1,000 micrometers (US EPA, 2010). As a frame of reference, a human hair has a diameter of approximately 50 micrometers. The suspended particles vary in size, composition and origin. It is convenient to classify particles by their aerodynamic properties because, (a) these properties govern the transport and removal of particles from the air, (b) they also govern their deposition within the respiratory system and (c) they are associated with the chemical composition and sources of particles (WHO, 2003). 2.4.1 Physical Characteristic The physical attributes of airborne particulates include mass concentration and size distribution. the size is from a few nanometers (nm) to ten of micrometers ( µm) in diameter. Size is the single most important determinant of the properties of particles and it has implications on formation, physical and chemical properties, transformation, transport, and removal of particles from the atmosphere. Ambient levels of mass concentration are measured in micrograms per cubic meter (ÃŽÂ ¼g/m3), size attributes are usually measured in aerodynamic diameter. Particulate matter (PM) exceeding 2.5 microns (ÃŽÂ ¼m) in aerodynamic diameter is generally defined as coarse particles, while particles smaller than 2.5 microns (PM2.5) are called fine particles (World Bank Group, 1998). Particles of any substances that are less than 10 or 2.5 micrometres diameter. Particles in this size range make up a large proportion of dust that can be drawn deep into the lungs. Larger particles tend to be tr apped in the nose, mouth or throat. The concentration and other characteristics of suspended particulate matter are determined by the presence and activity of sources. Once formed, particles change their size and composition by condensation or evaporation, by coagulating with other particles or by chemical reactions (Seinfeld and Pandis 1998). Pohjola et al., (2000), found that meteorological factors such as wind speed and direction, temperature, amount of precipitation, and the height of the atmospheric boundary layer, are most important in governing the concentration variations of particulate matter. The highest PM concentrations are often reported during stable meteorological conditions such as inversion with low wind speeds (Pohjola et al. 2004). Also the physical and chemical processes affecting the particles are regulated to a great extent by meteorological factors. 2.4.2 Chemical Characteristic The chemical composition of the particulate matter is also important. The chemical composition of PM is highly variable due to pollution sources, chemical reactions in the atmosphere, long-range transport effects and meteorological conditions. Absorption and heterogeneous nucleation of vapor phase pollutants onto existing particles can create toxic particulate matter (US EPA, 2010). The chemical properties vary depending on sources of particles. It is important to note that particulates are not one particular chemical substance but a classification of particles by size rather then chemical properties.The acid component of particulate matter, and most of its mutagenic activity, are generally contained in fine particles, although some coarse acid droplets are also present in fog. Particles interact with various substances in the air to form organic or inorganic chemical compounds. The most common combinations of fine particles are those with sulphates (World Bank Group, 1998). The rela tive abundance of the major chemical components, termed as bulk chemical composition and also about trace element and strong acid contents was reviewed in the studies of Harrison and Jones (1995) and Harrison and Yin (2000). In addition to the bulk composition, Harrison and Yin (2000) also discussed trace element and strong acid contents. In the United States, sulphate ions account for about 40% of fine particulates and may also be present in concentrations exceeding 10 ÃŽÂ ¼g/m3 (US EPA, 1982). 2.5 PARTICULATE MATTER HEALTH EFFECT There are a very limited number of studies that relate air pollution to its health impact in Malaysia. The lack of data gathering for environmental epidemiological analysis makes it difficult to estimate the health impact of air pollution (Afroz et al., 2003). Whilst epidemiological studies have consistently demonstrated adverse effects of particulate matter exposure on human health, the mechanism of effect is currently unclear (Harrisonu Yin, 2000). The US Environmental Protection Agencys 1996 Air Quality Criteria for Particulate Matter reviewed the physiologic, toxicology, and epidemiologic studies related to the inhalation, deposition and health effects of PM exposures (US EPA, 1997). Some research has identified several plausible biological mechanisms for both the initial pulmonary injury and the consequent systemic effects (Neas, 1999). The respiratory system is the major route of entry for airborne particulates. The deposition of particulates in different parts of the human respiratory system depends on particle size, shape, density, and individual breathing patterns (mouth or nose breathing) (World Bank Group, 1998). In adults, PM exposure was associated with increased incidence of respiratory symptoms, transient decrements in pulmonary function levels, and the onset of chronic pulmonary disease in adults (Neas, 1999). Seaton (1995), has identified several plausible biological mechanisms for both the initial pulmonary injury and the consequent systemic effects following PM exposure and the initial pulmonary injury may be related to one or more properties of PM and its constituents including physical, chemical and biological characteristics. Several hypotheses have been proposed to explain the path physiology of PM induced health effects. The most obvious mechanism involves the reduction in pulmonary function in response to the pulmonary inflammation. In the hypoxia hypothesis, the susceptible population consists of individuals with severe respiratory disease whose pulmonary reserve capacity is already near the minimum compatible with life. Exposure to PM further lowers their pulmonary function le vels and results in emergency hospitalization and death (Neas, 1999) Children are especially susceptible to particulate matter pollution for several reasons, their respiratory systems are still developing, they breathe more air (and air pollution) per pound of body weight than adults and theyre more likely to be active outdoors. Older adults are also more likely to be affected by particulate matter pollution, possibly because they are more likely to have chronic heart or lung diseases than younger people. In addition, people who have heart or lung disease, such as congestive heart failure, angina, chronic obstructive pulmonary disease, emphysema or asthma, are likely to experience health effects earlier and at lower particulate matter pollution levels than healthy people (American Lung Association, 1996). The capacity of particulate matter to produce adverse health effects in humans depends on its deposition in the respiratory tract. Particle size, shape, and density affect deposition rates. The most important characteristics influencing the deposition of particles in the respiratory system are size and aerodynamic properties. In Malaysian Ambient Air Quality Guidelines (MAAQG), the level of PM10 concentrations are, 150 micrograms per cubic meter ( µg/m3) for 24 hour and 50 micrograms per cubic meter ( µg/m3) for the annual (Department of Environment, Malaysia, 2010). Some tiny pieces of particulate matter, PM10, are small enough to pass from our lungs to our bloodstream. PM can alter the bodys defense systems against foreign materials, damage lung tissues, aggravate existing respiratory and cardiovascular disease, and can lead to cancer. In some cases, PM exposure can even lead to premature death. Adverse health effects have been associated with exposures to PM over both short periods (such as a day) and longer periods (a year or more). The people who are most at risk are people with asthma, influenza, lung, heart, or cardiovascular disease, the elderly, and children. The human immune system developed in a time and environment where dust was made of large particles. Humans have developed a means of protecting themselves against these large particles. Particles larger than 10 microns generally get caught in the nose and throat, never making it as far as the lungs. Unfortunately, more recent human activity has created many particles that are much s maller, which can make it past our natural defenses, and can enter our systems (Fierro, 2000). The size of particles is directly linked to their potential for causing health problems. Most concerned about particles that are 10 micrometers in diameter or smaller because those are the particles that generally pass through the throat and nose and enter the lungs. Once inhaled, these particles can affect the heart and lungs and cause serious health effects. EPA groups particle pollution into two categories: Inhalable coarse particles, such as those found near roadways and dusty industries, are larger than 2.5 micrometers and smaller than 10 micrometers in diameter. Fine particles, such as those found in smoke and haze, are 2.5 micrometers in diameter and smaller. These particles can be directly emitted from sources such as forest fires, or they can form when gases emitted from power plants, industries and automobiles react in the air.

The political views of the federalist and the republicans towards the government of the United States of America were different.

Abortion and Ethics Essay -- Life Pregnancy Fetus Papers

Abortion and Ethics According to the Websterà ¢s New World Dictionary, the first definition of abortion is the spontaneous act in which the body expels an embryo or fetus before it is able to survive, miscarriage (Neufeldt & Guralnik, 4). Yet others define abortion as à £the termination of a pregnancy with resulting death of the human fetus,à ¤ relating more to the planned procedures to produce this specific response (Ashley & Oà ¢Rourke, 141). In our society we have taken on this second view of the meaning, rather than abortion being a spontaneous act, it is a deliberate procedure sought by the mother that removes an embryo or fetus. This deliberate act has arisen throughout a controversial history. Before the procedures were made legal, women used many primitive methods. Some of these methods include jumping from great heights, having others jump on the pregnant womanà ¢s abdomen, ingestion of toxic substances, and the use of invasive probes such as sticks, knitting needles, or wire hangers (Callahan, 252). Although these primitive procedures might result in an abortion, they were unsafe for the women who endured them. Abortion in the United States was illegal until the early 1970s. Once legalized, abortions were localized to the coastal densely populated cities, such as in the states California and New York. Abortion was legalized nation wide on January 22, 1973 due to the efforts the key court cases of Roe v. Wade, and Doe v. Botton. Roe was an unmarried woman from Texas that wanted to challenge the abortion laws because she herself wanted to have the procedure to relieve the unborn child she carried. The second case, Doe v. Botton had a different outlook on the justification for abortion. Doe, a married... ...cities.com/ourlady_dal/abortion2.htm Knight, James, Joan Callahan.

Assesing the Curriculum for Special Education Essay

School can be particularly challenging for children with special needs, including those with attention-deficit hyperactivity disorder or ADHD, who often experience poor academic performance, behavior problems, and difficulties with social interaction. The situation can be further complicated by the fact that there is no typical, predictable classroom style common to all children with special needs, for that matter. It can also be hard for parents to tell how much of any problem identified by a teacher falls into the normal range of a child development, for example how much is due to ADHD, and how much is due to coexisting problem such as learning disability, anxiety disorder, or disruptive behavior and others. Add to this fact that the public school system here in the Philippines may not have Individualized Education Program (IEP) that will meet the needs of these special children. In this study, the researcher will use different basic methods of assessing special education curriculum how it may be integrated into the mainstream or general education particularly in the Philippine public school system, without compromising quality of education. Objectives of the Study The objectives of this research proposal are a) to assess the basic curriculum of special education; b) to identify the positive and negative effect of the integration of such curriculum with the general education in the mainstream classroom and c) to identify effective classroom and teaching styles of special education. Statement of the Problem So many parents who have a child with special needs, particularly ADHD, have a dilemma when it comes to placing their children in public school system in the Philippines, since they are not included in the public school curriculum. And most public school teachers, if not some, may not be fully aware of the special needs of a child with ADHD and for that matter, does not have special skills in dealing with such students. Only special schools or some private schools deal with special children or include special education in their general education curriculum. On November 2005, my six-year old daughter was diagnosed with attention-deficit hyperactivity disorder (ADHD). Since she was moving up to first grade, sending her to a public school was practical and a good choice, yet doubtful that the public school system has educational intervention for children with special needs like her, within the mainstream classroom setting. Her developmental pediatrician suggested for a behavioral therapy and tutorial through a SPED School, for that matter but it was important for my child to interact with children her age in a normal classroom setting, so the plan did not push through. . Scope and Limitation The Department of Education often stresses the need for a good public education which is free and accessible to every child in the country, including children with special needs, particularly those with Attention-deficit hyperactivity disorder (ADHD) who came from all levels of society. It is therefore important to assess and evaluate special education curriculum to see if it can be integrated in the mainstream classroom. The special education evaluation process requires the school district to assess the student in all areas related to the suspected disability as well as conducting a comprehensive educational assessment for integration to happen in a normal classroom. Most educators believe that children with disabilities and nondisabled children should be taught together whenever possible. Isolating children with disabilities may lower their self-esteem and may reduce their ability to deal with other people. The practice of integrating children with disabilities into regular school programs is called mainstreaming, or inclusion. Students with disabilities attend special classrooms or schools only if their need for very specialized services makes mainstreaming impossible. Many children with disabilities attend regular classes most of the school day: They work with a specially trained teacher for part of each day to improve specific skills. These sessions may be held in a classroom  called a resource room, which may be equipped with such materials as Braille typewriters and relief maps for blind students. Other students with disabilities attend special classes most of the day but join the rest of the children for certain activities. For example, students with mental retardation (MR) may join other children who do not have MR for art and physical education. Although the place where instruction occurs (the setting) is seen as important in the field of special education, the types of curricular modifications and interventions may be a more important area to focus on in the future. Hypothesis This research is important in giving helpful ideas in relation to a child with special needs, especially with ADHD, and the effect of learnings he will get, especially in the public school setting, which gives free education to all. This research will help foster a child’s academic and social success in school through a good curriculum designed specifically for his needs, by assessing general education curriculum through the Curriculum-based evaluation and other related tools for assessment and evaluation. This research will deal on the questions: 1. What type of school-related challenges children face most often? 2. How effective is the special education curriculum to children with special needs and what areas need improvement? 3. Which classroom structures, teachings styles and accommodations can best support the child’s learning? 4. How can the integration affect the mainstream classroom?

Curriculum-based measurement: the emerging alternative. Exceptional Children, 52(3), 219-232. Deno introduces CBM as an alternative assessment approach that is both valid and reliable. He discusses the advantages and disadvantages of informal observation and also standardized commercial achievement tests. Dizon, Edilberto I. , Ed. D. An Article: Educational Intervention for Children with Attention-Deficit Hyperactivity Disorder. UP College of Education, 1998. This article discusses the priorities and guidelines in teaching children with ADHD. The author discussed how to assess the classroom that would enable teachers to decide on appropriate placement and design a customized educational program for the child, even at a mainstream classroom. He also talked about structure within in the classroom, its organization of chairs and tables and seating arrangements and the workspace for the child. It is also important to assess the curriculum and its contents. To make sure that there is provision of task-analyzing for the different skills of the child, to adopt anticipatory teaching and guidance which emphasize foresight and preventive intervention. Supervisors should be able to assess if teachers are able to focus on processes as much as outcome in their teaching and are able implement good behavioral management inside the classroom.

Retrieved [3/22/2008] from http://www. cast. org/publications/ncac/ncac_curriculumbe. html This publication includes discussions on academic assessment, which is a long-standing tradition in education. Assessment usually involves measurement of student progress for the purpose of informing. One level of informing is identification or eligibility decision-making, a second level is that of informing instruction. Traditional assessment instruments have limitations which restrict their application for instructional program planning. It also introduces alternative assessment procedures appearing in educational literature in the last 20 years are Curriculum-Based Evaluations (CBE). Whereas standardized commercial achievement tests measure broad curriculum areas and/or skills, CBE measures specific skills that are presently being taught in the classroom, usually in basic skills. It further states that assessment usually involves measurement of student progress for the purpose of informing. The author reviewed the beginning of CBE, wherein many of its systems had their beginnings in the special education domain. In some cases, research began specifically in the self-contained special education classroom. In others, the roots of the measurement system sprang from the desire to most appropriately integrate students with disabilities into the general education classroom. The tools described here under the name of Curriculum-Based Evaluations all had important roles and made contributions in research and practice in the general education class. Peters, Helen. An Article: Understanding and Educating Children with ADHD. Winston Churchill Fellow. 1998 This article was written as an overview in educating children with ADHD.

In classroom assessment, the author came up with four important questions in order for a teacher to have an effective classroom management. Understanding the different learning styles for special children was also discussed in this article. A series of questions were asked when thinking how to support the learning needs of the ADHD child was also included in this paper. The author also mentioned the school’s response to academic failure and the importance of visual display of lessons. Reiff, Michael I. , & Tippins, Sherill, (2004).
