My area – Earls Court a very weird and different area

Earls Court a very weird and different area. But that is not the opinion of the people living there that's just my opinion. Earls Court is a different area; I like to think of it as a little town not just some area in the heart of Kensington. The streets are always covered in old crisp packets and used condoms and there always seems to be puddles of water or some liquid that never seem to dry up. Behind my house is a private garden which, on a cold winter's morning is as misty as the peak of Mount Everest and the Scottish Highlands put together. This garden is run by a Garden Committee which is headed up by a woman who changes her hair colour every single week, for example last week the woman's hair was black and this week it is about as red as Manchester United's football shirt. In this garden there is a tennis court which is set up during the summer and the rest of the year the poles on which the nets hang are used by myself and about ten other mates as football posts. However the woman with the ever changing hair colour always seems to see us and come out and confiscate the ball even though her house is about from the school to Shepherds Bush tube station. The rules for this garden are extremely, I can't think of the word, hang on, ah yes, STUPID. You are not allowed to play football, play music, play and instrument, ride your bikes or any type of game that can damage the plants. It might as well be an outdoor prison. About 2 minutes walk from my house is a giant Tesco superstore; it claims to sell everything but the trouble is you can never find everything because they keep changing where everything is so I'll probably never know if they do sell everything. I remember about a month ago now, me and my mate Gav were in Tesco's and I had to use the toilet so I told him to wait downstairs. As I came back down the stairs my hat fell off down to the ground floor below; I ran down the stairs only to find my hat had disappeared and Gav standing where it had landed with an evil little grin on his face. Then a Jamaican security guard came up to us and said, † What are you doing†, and I because I didn't want to get in trouble said in a very angry and serious voice, † Gav man, where the hell did you put my hat? , the security guard told Gav to get my hat from where he had hidden it; amongst the boxes of wine. He gave it to me and we were just about to get away without getting into too much trouble when Gav, being the stupid idiot that he is, made the mistake of bursting into a fit of laughter when the guard had just turned away; not when he was out of earshot but when he had just turned his back so the guard heard, turned around, called his colleague and literally and I emphasise the literally, threw us out of the store onto the pavement; where Gav and I proceeded to laugh our heads off. But perhaps the most prominent building in my area is the office complex; just around the corner from my house; down a side road; which runs past a Gospel church. In this complex there is about 6 or 7 cameras 2 of which overlook the gate going in. On a dark and quiet Saturday night if there is nothing else to do; what me and my mates like doing is trying to get into the complex without being spotted by the 20 or so security guards just inside the main entrance. One time I dared a boy called Adam to run in and touch the sign that is about 10 metres in front of the front door. There were about five of us including Adam; he ran past the gate, past the cameras, touched the sign, and ran back. By this time all of the guards were up out of their seats and sprinting out of the door; I was the last one to notice; Adam sprints by me screaming like a little girl and everyone is running, I hadn't noticed what was happening and when I turned around from my hiding place about 15 metres from the gate; about four of the guards were coming through the gate, I stood up and started sprinting like a cheetah chasing a zebra. When I came to the fork I went right whilst everyone else had gone left down to Adam's house, I heard one of guards say, â€Å"You lot go left while we go right, we're going to get these kids†, I though, Christ their going to catch me; I wouldn't have been so worried if they weren't carrying holsters around which could have contained a gun. I ran between and over the parked cars and over a wall about a metre or two high and hid. I waited until they had given up and then I emerged from the shadow of the crucifix, triumphant in the fact that I had given trained security guards the slip. As I mentioned before I there is Gospel church near my house which has a bright green spire and on a Sunday morning and Wednesday evening it is absolutely bursting with music and singing. But the bad thing about this is that all of the cars of the church goers block up the parking lot; the only place that we are allowed to play football. But there are other more interesting things about my area like the fact that a woman fell of the roof of my house into my garden and I still don't know how she got up there. Also about three weeks ago a complete nutter of a man was on the roof of an estate brandishing and firing a rifle. All of the surrounding roads were closed off and armed police and for some reason there was riot police there as well. Nobody was hurt except the guy firing the gun who shot himself in the leg before being arrested. Once I was riding my bike to my mate's house and a tiny, little homosexual man stood in the way on purpose even though he had about a 10 second delay before I was near enough to hurt him; he stepped out and then said in a squeaky little voice â€Å"Watch where your going you stupid little s**t†, I yelled back at him some obscenities that I cannot mention here. Around my area there is a lot of refugees who go around asking people for money. Once I was walking to school when about five of them came up to me and asked me to give them i10; I just looked at them and said, â€Å"You got to be joking†, the leader looked at me really seriously and said, â€Å"I am being seriously perfect†, and that just made me laugh. I think he meant to say, â€Å"I am being perfectly serious†, but got confused. The leader then grabbed me and said, â€Å"give me i10 now†, he was only about as tall as me so I kneed him in his groin and the rest just backed off because a security guard had come out to see what was going on. The guard ‘escorted' the leader off the premises and by that I mean threw onto one of the islands in the middle of the road. There is a tall, red brick building just around the corner from my house which used to be where the local police force lived for free until it was turned into a council flat. There is a woman called Louise who is about 40 years old and has a problem with kids. She is as thin as rake and is about medium height. Her nose is crooked and she has a terribly squeaky voice like a rusty bike chain. She has a balcony coming out of the back of her house which she likes to use for taking pictures of people passing especially kids. When we make noise she comes out and starts going on about how we are making too much noise, and then we confront her about taking pictures of us she just goes quiet and slithers off quietly like the snake that she is. Just last Sunday she came out and starting having a go at us; but when we started confronting her about taking pictures of us she said she'd even take videos of us; we just said but that's illegal, she said so is noise disturbance; then I said â€Å"but which one do you think is more serious†, at which she just walked off and I called after her â€Å"I thought so! â€Å". She wears quite trampy clothes and she probably only has one piece of clean clothing in her whole life. Around my area there are a lot of kids who wander around looking for kids to mug, but I know them so they don't try to mug me. However when I was in first year there was some kids that I didn't know trying to mug people, and once I was on my way home from school and I must have looked like a right idiot with my catholic schoolboy uniform all neat and tidy. They were walking on the other side of the road and I saw them look at me then cross the road towards me; so I crossed the road to where they had been. They were then behind me and had turned around and started walking quite quickly towards me; now you have go to remember that I was a little first year so I couldn't fight off two 16+year olds, so I started jogging, they started jogging, I picked up the pace, so did they, I was coming up to Tesco's now so I sprinted through the back way through the car park into the store up to the first floor and out through the first floor exit. As I went down the stairs I could see them through the 12ft high windows searching for me jogging through the aisles so I started jogging across the large 6 lane road to my house. As I rounded the corner I saw them come out the main entrance, point towards me and start sprinting, so I just sprinted to my house and got through the front door in record time. I opened two doors in about 6 seconds. As I said earlier I consider Earls Court like a little town; a little town with its own high street with every shop its own cinema and even its own arena and park. But with little towns there comes problems. On Thursday mornings there are piles of black bin bags waiting for the bin men to come and take them away; it smells about as bad as rotten fish and eggs put together. You trip over the bags that are strewn all over the pavement. As I go down to school I go past a bright, mustard yellow estate which all the dump trucks come out of and so that stinks even more and there are kids on the estate that spit down on people going past. All in all I think my area has some good points like the fact that most of my friends live there but there are some bad points like all the crime and rubbish on the streets. But it is my area, I've lived there all my life and I love it.

What makes a building green

This paper explores what makes building material green. Green building materials are materials that have less impact on the environment, human health, economy and productivity as well. Since buildings have significant impacts of the environment, design professional have resolved to the use of green materials in building process so as to eliminate waste and to conserve the environment. Construction of buildings consumes a lot of energy use and also emits a lot of carbon dioxide in the environment. Construction also consumes a lot of raw material each year. Buildings made from green material are healthier, energy efficient than other buildings and more durable. This paper will concisely articulate what sustainability and green building products are. This paper will also determine and explore if a product is green. Lastly, this paper will evaluate the relative greenness of different products. Table of contents Introduction 4 What is Sustainability? 5 Exploration 7 Green Building Products 7 How to determine a green product 10 Implementation 12 Conclusion 21 Works Cited 22 What makes a building material Green? Introduction Construction of buildings has intense environmental, health, economic and productivity impacts. 20% of global energy use is from buildings. Buildings also emit 20% of carbon dioxide to the environment. For these reasons, many builders have resolved in the use of green building since it has financial, health and environmental benefits. Many countries that practise sustainability have also supported the green building movement. Statistics in the U. S. show that green building construction will rise from 2% in 2005 to 10% of the constructed buildings by the year 2010 and therefore the country will have save about $30. billion. The green building initiatives in the U. S. has established more that 80 green building programs both regionally and locally. The local governments are also involved in the promotion of the green building by creating innovating ways of supporting the programs (NACo Green Government Initiative 1). In Europe and North America, many architects are involved in designi ng sustainable designs also known as the green building designs. This is due to their clients’ demands and their recognition in protecting the environment. Globally, there is a lot of support form the people in establishing environmental friendly buildings (Pearce 129). There is need of financing low energy buildings so as to enhance performance. Governments should initiate more programs that enhance building of green buildings. This process will therefore eliminate the environmental hazards and increase global health standards while reducing costs (Baden et al. 8-1). The green building has made tremendous benefits globally. The initiative has help in the conservation of the environment, health and financial issues (NACo Green Government Initiative 1). What is Sustainability? Sustainability is being responsible to the world especially environment and in energy saving. Sustainability is a social program that helps in energy saving and other global protection of the environment. It deals with issues on the environment, economy and society (Langdon 6). In order for the building process to be sustainable, there is need of taking care of the environment, health issues and the finances of the society. Sustainability has led to the establishment of green buildings since it helps in the protecting the air we breath (Wiaderski 2). Green buildings prevent the particles such as Volatile Organic Compounds off-gassings, carcinogenic among other airborne particles from filling people’s lungs. Green building eliminates the use of paints and adhesives that emits these volatile organic compounds. The process of using green materials such as the Dryvit coatings and adhesives, which are water based helps in the elimination of the harmful chemicals in the environment (Wiaderski 3). Many hospitals and schools are being sustainable by using green materials in the constructions process. This has therefore helped in ensuring that people live in environments that are safe and healthy. For sustainability to be ensured, designers are now using green materials that are environmental friendly (Wiaderski 3). To ensure that there is sustainability, there are many building standards that have been introduced. For example the National-recognized green building rating standards have been established for the builders and designers to ensure that they are making buildings that are protect the environment and the health standards of the people (NACo Green Government Initiative 3). In sustainability, builders try to eliminate the use of fibreglass insulation and other such products in order to protect the human health standards. This is the reason why builders use the Dryvit system in insulation since it helps in the improvement of the quality of the air in building (Wiaderski 4). To ensure sustainability in green building construction and design, the major factors to consider are efficiency in energy and other resources. This is done by ensuring that the designed buildings should of low energy consumption. This is practical by the use of the Dryvit systems which adds a constant insulation layer on the exterior walls of a building. The Dryvit system also minimizes the thermal breaks of the building. This process of insulation of the exterior wall helps in energy conservation and it also improves the indoor air quality of a building. Insulation also helps in resisting bad weather conditions. Insulation of the exterior walls is also advantageous to the northern climates since it increase the temperature of the wall cavity which therefore helps in the minimization of the condensation process inside the cavity of the walls. This process is also advantageous to the southern climate since it helps in reducing the air infiltration therefore protecting the wall cavity by minimising the entry of the heavily saturated moist air. This helps in the reducing mold growth and condensation on the wall cavity (Wiaderski 4). A study conducted by Oak Ridge National Laboratories on the building material concludes that the Dryvit wall system is a building system that conserves energy of the wall system and therefore it was suggested that the system should be used in the commercial construction of the U. S. buildings (Kosny et al. Whole Wall Rating / Label for Dryvit Wall System Steady State Thermal Analysis). For sustainability, designers need to use products that protect the economy of the people and the country. Green products are durable and they also don’t need be maintained and repaired constantly. One practical example is the use of the Dryvit systems which is adaptable. This systems’ repair and main tenance process does not need to be harshly removed nor does not require demolition (Wiaderski 5). The base coat of the green products has a reinforced mesh that is embedded on them to ensure durability and resistance for more than 30 years. Since the green products are durable and resistant, they have been found to be cost effective. For example the Dryvit systems have been found to be cost effective due to its durability and other advantageous aspects (Egan et al. Projected Life Cycle Cost of Exterior Insulation Finish Systems). There are green building practices that help in the sustainability. This includes the use of the indoor air quality. In this practice, the designers and the builders ensure that they make buildings that have quality indoor air systems. This practice involves concepts such as relationships of the ventilations and the indoor air. Other concepts include the use of the simple dose in building process and source identification. Other concepts include strategies and options of source control and design and operations of ventilation systems. There are other concepts such as the selection and specification of material and procedure of construction. Lastly, other concepts for best practices in the construction process include the maintenance, operation and renovations (Levin Best Sustainable Indoor Air Quality Practices in Commercial Buildings). Exploration Green Building Products Green building products are materials that have less or none impacts of the environment. These materials are not hazardous materials and they allow for the eradication of the other hazardous building products. There are many classifications of green products. In the classification of the green building products, the building products are evaluates using their negative and positive impacts and thereafter, the products with most positives are classified as a green product (Wilson Building Materials). There are products that fall into multiple classifications and others that fall into one classification. The classifications of the green products include durability, zero-gassing, toxicity, longevity and resource efficiency. Other classifications include environmental impacts and energy efficiency. Green products are building products with various environmental and cost benefits. Green products have long-term performance benefits (Wiaderski 2). Green products are combined with the building designs to help in the reduction of the negative environmental effects. Deign and building professions the use the green designs ensure that they give vigilant attention to the aspects that oversee the projects’ designs. Buildings made from green products are airtight and therefore keeps the buildings from interior and exterior contaminations. Constructions that use green materials ensure that there is a healthy environment to the people in the society (Wiaderski 2). The green products are classified in the category of energy rating, life cycle costs and health conditions (Wiaderski 4). The common features of the green buildings include the energy conservation in which include factors such insulation, mechanical equipment and efficient lights as well. The other feature include the utilization of solar energy in which factors such as space heating, cooling and water heating are considered. There is also the water conservation feature which ensures that there are fixtures of low consumption. Other features of the green products include the recycled material incorporation and materials with low emissions improved indoor air quality ventilation (Levin Best Sustainable Indoor Air Quality Practices in Commercial Buildings). The other features of the green products include the development sites that less destructive to the environments which include processes such as run-off control, water courses and other natural habitats preservations. The other feature is the treatment of the on-site waste water. There are also features such the use of refrigeration and fire systems that have compounds that reduce or eliminate ozone-depletion. The other feature include the use of life cycled materials and assessment of the building projects’ environmental impacts. The last feature of the green products is the use of recycled products (Levin Best Sustainable Indoor Air Quality Practices in Commercial Buildings). Green building materials are sustainable to the environment since they help in the improvement of the health standards of the people. These are recycled materials that are highly durable. These products are categorised in criteria such as the resource efficient products which include products such salvage products, post-consumer and pre-consumer products. This category also includes products such as waste agricultural materials. The green products also include product that are non toxic which include products such as the natural processed and non ozone-depletion products. This category also includes non hazardous products and other environmental protection products. The other category of the green products includes the energy and the water efficiency products which include products such heat reducing building components and energy conserving equipments. Other products include the energy renewable equipment and water conserving equipments (Port 3). The last category of the green products includes the safe and healthy built environment products. These products include the non-pollutant products and products that reduce the contamination spread. Other products that are in this category include the indoor pollutants removers’ products and products that are used in warning about health hazards. Other products include that are light improvers and help in the control of noise. Lastly, this category includes products that help in community well-being’s enhancement (Port 3). Homes that are made from green products are durable, healthier and more efficient that other home. Components of a green home include selection of strategic sites to reduce environmental impacts. The other component is designs that help in conserving water and energy and waste. The other components include designs that minimize usage of materials and therefore reduce the needs to maintain the homes. Homes made from the green materials possess components that are recycled and are therefore efficient to the energy conservation. These components also use sources that are renewable (NACo Green Government Initiative 1). Green products have been used by the USA’s Green Building Resource Centre. These products help in the conserving the energy, water and natural resources. The products also help in the protection of the indoor environment of the buildings (Levin 465-482). How to determine a green product Green products are determined by how they meet the requirements of the performance. These requirements include the factors such as being sufficient and durable. The other requirements of the performance include the strength predictability and stability. Other requirements are such as moisture, decay and bio-contamination resistance and have less cost compared to other products. The other requirement includes factors of being non-toxic and non-hazardous to the people around. Lastly, these products are able to be efficiently and effectively installed (Pearce 3). The other way to determine whether a product is green is by ensuring that the product is not negatively an impact to the ecosystems. In this way, one should ensure that the product is harvested sustainably and is also non-accumulative and non-toxic to the environment. Another way of determining the product id this category is by ensuring that the product is recyclable and is cost effective since it does not have to be repair and maintained. Products in this criterion also produce waste that can be reused and recovered (Pearce 4). Another way to determine the green products is by ensuring that the products are able to be renewed. In this criterion, the products are checked is they are renewable and if they can be harvested sustainably. The other things to consider are whether the products are materials that are closed loop. This means that the products should be checked whether they are reused or recycled. Other things to consider in this criterion are things such as whether the product is adaptable or reusable and also whether they are non-renewable. Lastly, the products are checked whether they use unsustainable material (Pearce 5). The other factors that determine whether a product is green include factors such as green products saves energy. In this factor the products are determined whether they help in the reduction of the heating and cooling loads. Other factors are whether the products use reduces energy levels. Lastly, the green products are products that can produce energy. Products can be determined as green products when they protect the natural resources. In this factor, the products are checked whether they have recycled content and whether they are made from agricultural waste. Products that use less material and are made from materials that are swiftly renewable also fall in this category. The products in this category are those that are made from managed forest and are also products that are salvaged (OFGEM A review of the Energy Efficiency Commitment 2002-2005). The other factor that can make a product green is when they can conserve water. The products include those that can conserve and consume less water. The other way to determine whether the products are green is by checking whether the products have contributed in the safety and healthiness of the indoor environment. In this way the products are determined whether that have effects on the indoors. Such products should not release and pollutants in the buildings. Products in this category do not remove pollutants in the indoor environment (Mendell 227-236). Lastly, products can be determined to be green when they reduce the impacts of buildings on the community. These products are those that moderate the storm water effects and also help in the provision of access to transportation modes that are alternatives to other transportation modes. These are also products that treat without the use of the chemicals and also do not components that deplete the ozone (Levin 173-175). Practical examples of the buildings and projects which are among the 10 winners of â€Å"What makes it green 2008 winners† that have been used in the illustration of the green products include the Bertschi School in Seattle WA which was helped the people in the area to minimize the usage of transportation. The other example is the Centre of Urban Waters project in the Tacoma that is used in storm water runoff reduction. The other illustration is of the Corvallis CoHousing project in the Corvallis which has ensure that the there is minimization of the use of the resources through sharing. There is also the illustration of Kitsap Sustainable Energy and Economic Development that encourages clean energy development (Dispenza Green Building Elements: What makes it Green? 2008 Winners). Implementation The greenness of products can be evaluated from different perspectives for example according to their durability, stability, strength and speed. The greenness of products can be judged from the way a product or a material reduces its demand for landfills especially the cement company Ceratech in the U. S which makes use of recycled fly ash to manufacture Redimax cement. Ceratech, Inc a technology company for materials focuses in the enlargement and the commercialization of inventive green cement sustainable knowledge (Stone 1). The Romans used the volcanic ash (Pozzolan) which they mixed together with lime in order to manufacture the cement for constructing Coliseums, Pantheon and Pont du Gard Aqueduct in Southern France which are strong to date. Pozzolans include fly ash, timber ash, slag and residue from publicly consequential garbage which are blazed at elevated temperatures. The Ceratech Company uses fly ash in producing Redimax which is their cement for all household productions though it manufactures its cement locally by using Class N volcanic ash pozzolans to produce their cement. Fly residue, is a diaphanously alienated coal incineration derivative which is collected by electrostatic precipitators from the chimney gases. A rough calculation of 60% which equals to 42 M tons of fly ash is land filled in the U. S. per annum (Fanney et al Second International Green Building Conference and Exposition). There is a reduction in carbon footprint of concrete due to the replacement of Portland cement with fly ash since the production of a single ton of Portland cement gives production to roughly one ton of carbon dioxide. Ceratech technology of revolutionary cement is a footstep of change to the industry of construction by providing the cement which is environmental friendly and is engineered for its potency, momentum, permanence and its long-standing toughness. Fly ash which is a post industrial fritter away stream is utilised by Ceratech, in order to produce structural cement of high presentation worldwide encompassing of more than 90%materials from cast-off waste (Stone 3). The recycling process preserves the virgin material hence eliminating the mining of raw materials which are needed to produce Portland cement. It also reduces the emissions of carbon dioxide by making the replacement of Portla1nd cement to every ton of Portla1nd cement produced. World wide, Portland cement gives a contribution of 6% to 8% of all the gases of Carbon dioxide released per year (Consoli et al Guideline for Life-Cycle Assessment: A `Code of Practice' Society of Environmental Toxicology and Chemistry). There is also the reduction of the energy consumed since the Ceratech Company is produced by the use of an amalgamation process of low energy powder against the calcining process of high temperatures. The Ceratech Company has done a careful manufacturing of their cement for the applications where strength, durability and strength are the preferred distinctiveness of a substance. There is competence of energy since their Pozzolanic cement requires 99% less energy to produce a corresponding amount of cement from Portland (CERATECH Green Sustainable Structural Building Material Technology: Driving Change through Innovative Thinking). The logistics behind the Redimax cement is that, it is shipped, handled, stored and batched like the Portland cement and it can either be transported by rail, truck or barge. Since the dangerous constituent of sustainable1 construction is durability, there is a designed subject to allow Ceratech maximizing the performance characteristics in order to come up with the constructing concrete which will last for long. The deterioration resistant of Redimax, low permeability does helps in resisting the establishment of the corrosive cell within the ma1trix of the concrete and in so doing there is eradication of characteristic costs which associate with the traditional corrosion performances of protection, coatings and sacrificial fundamentals. Hence there is extended cycle of the life of a construction. The strengths of green material can also result from its comprehensive strength since the cement concrete acquires rapid characteristic of hardening so that it gives an easy generation of more than five hours comprehensive strengths of 2,000 psi without any negative impact working time (CERATECH Green Sustainable Structural Building Material Technology: Driving Change through Innovative Thinking). The Sulfate Resistance of the cement evaluates the greenness of the product by examining its uniform density and extreme fine pore structure which increases its resistance to the penetration by water or substance. There is evaluation of greenness of products in terms of Improved Flexural Strengths whereby when they are associated with Redimax there is a typical of 15% to 18% compressive strengths of correspondence. There is an allowance of reduced loading stress from the cement in order to substrate for slab on grade work more effectively than the Portland cement concrete. The enhancement of flexural capabilities does provide for potential incorporation to longer spans fore important applications which are structural (CERATECH Green Sustainable Structural Building Material Technology: Driving Change through Innovative Thinking). The greenness of a product can be evaluated in terms of the expenses for instance the Ceratech construction expenses were reduced together with its direct and indirect value of the building project which leads o the enhancement of the breadth of a company’ s exclusive cement distinctiveness. The construction costs include reduced labour costs which are as a result of the compression of the project schedule. The compression also diminished costs, for charter items such as shoring organization, formwork and special apparatus. There is also the reduction of eliminate issues which are in association with the rejected concrete due to the discharge requirement of water within a period of 90 minutes. The construction cost reduction leads to the reduced prices in material costs by as much as 30% (CERATECH Green Sustainable Structural Building Material Technology: Driving Change through Innovative Thinking). There is also operating costs which lead to the decrease of heating and cooling costs due to decrease on the whole thermal mass of the building. There is also outstanding confrontation to damage from the liquefying congeal, scaling and chemical assaults and the extension of the suitability for local, situation and centralized taxes by means of GREEN inducement curriculum. There is also maximized reduction on saleable space expenses for example the reduced size structural mechanism by means of greater square recording. The evaluation of the greenness of a product can be gauged in terms of the innova1tion, aesthetics and environmental leadership. Innova1tion can be observed from the superior mechanical properties in order to give allowance to the increase in the usable space by decreasing the column footprints, breadth of the slab, the height of the ceiling and the increased free distance lengths. There is also the increase of 30% in the increase fire charges. The other evaluation of greenness in innovation on innovation is the creation of blast dead set against structures, the rapid build dry piled block structures utilizing the innovatory and also the design storm resistant colossal stonework structures (CERATECH Green Sustainable Structural Building Material Technology: Driving Change through Innovative Thinking). There is also the environmental leadership which entails the requirement of the technology of the product company as either stonework block concrete. This will do away with a single ton of carbon dioxide gas for every 3 yards of concrete. The efficiency, strength and safety of a product can brought out thr3ough greenness by the example of the technology of Ceratech cement technology which exceeds ASTM-C-1600 in all the groupings of testing. Whereby increase in the power gives allowance for greater suppleness of design, efficiency and the general presentation of building. The greenness of the product can also be observed from the efficiency of the design for instance in the Ceratech Company whereby the ultra high strength hollow core floor board consent to greater free duration extensions. There is reduction of overall weight of building whereby columns which cross sections can be reduced by a nearly percentage of 40%. There is also reduction of rebar requirements. The strength of the product can bring out its greenness like in the case of Ceratech who have compressive strengths to 10,000 psi using standard mix designs with high early strengths to 2,000npsi in 6hours (CERATECH Green Sustainable Structural Building Material Technology: Driving Change through Innovative Thinking). The use of green building construction, is of great benefit to the consumers since it is efficient in energy, water and materials, it minimizes waste and pollution and creates a better indoor environment. Designing of buildings is aimed at humanizing interior excellence of the surrounding which can bring into being benefits for workplaces and the productivity of the workers as well as the landlords. A proficient green structure can be strong enticement when giving promotion to the charter of residential or marketable space. According to environmental protection agencies, deprived interior air quality is an environmental threat to a nation. Whereas sick building syndrome causes fatigue and illness which is brought about by poor designed ventilations and the presence of biological contaminations for instance molds, bacteria and pollens. The indoor air pollutants can be as a result of smoking of tobacco, building resources, products for beautifying, practices for clearing out, pest management, supplying, dust together with other activities such as cleaning and heating up (Stone 4). Due to poor green construction, there is a possibility of occupants complaining of several indications such headache, irritations in the eyes, nose and exasperation of the throats, dry coughs, itchy skin, wooziness and vomiting, difficulty in concentrating, exhaustion and sensitivity to scents. Relieve from the suffering, comes about after leaving the building. T he Sick Building Syndrome reduces the efficiency of the workers which may lead to increased non-attendance. Green construction indemnifies appropriate exposure to air, condensed particulate substance and substitutes to pollution of chemical as long as preservation and modifying activities work in performance with the intention of the established green materials and systems when the construction took place (Stone 4). The elements of design of a construction play an important role in eradicating interior contaminants. Therefore, there is an importance of integrating permanent entryway features for example grills or grates which will be used to capture dirt and particulate substance at all entryways with heavy traffic. The buildings should also include controls of tenants for airflow, temperature and lightning. The possible options have to include task lighting, operable windows and under-floor heating, aeration (ventilation) and air habituation (HVAC) arrangements with personal diffusers. There should be a possibility of the proposal of the building maximizing the quantity of proscribed daylight that can reach interior regions which are occupied. The prohibited day lighting involves reflective exteriors and disseminating elements which enable sunshine diffusion while taking control of frown. Additionally, light sensors should be installed to supplement the total amount of sunshine to supply desirable lighting levels for the necessary errands (Lippiatt 37-45). The relative greenness of a product can be evaluated from scrutinizing the construction resources, supplying, and other products such as air fresheners, clearing products and pesticides which in the end result can discharge contaminants more or less incessantly. Therefore, there is a proposal of Formaldehyde-free materials for floor covering, furniture, fortifications and upper limits, lagging and finishes, sub-flooring and en suite breakfronts. Preferably all the bonding agents and paints should not have any fillings of Volatile Organic Content (VOC) but instead ordinary and water-based coverings should be used. Low and no-discharge grounds and flooring finishes, natural coverings of the floor are of greatly preferred to conventional carpeting (Stone 5). An observation from United States Environmental Protection Agency (USEPA) the financial benefits of residential green building, there is a production of $200-$400 in annual savings in energy from the houses which are built to Energy Star. This are all on heating, cooling and water heater related costs. The durability of the green home construction interprets to additional savings on the preservations over the existence of a home (Internal Revenue Service Treasury and IRS Provide Guidance on Energy Credit to Home Builders). There is an important role which is played by the counties in educating the residents and builders of homes, about saving energy and obtainable refunds, recognitions and other funding support for green structure and projects for home development (Weitz et al. 5810-5849). The counties can give an action of Clearinghouse of information for builders and confidential citizens who have an interest of capitalizing on the benefits of investments of their green building schemes. The incentives of finance in order to build green, come in different forms including credits from taxes, for individual taxpayers, accelerating process of giving permission for homebuilders and rebates from both power and water companies for doing the setting up of resource competent attributes in a residence (Roodman et al A Building Revolution: How Ecology and Health Concerns are Transforming Construction). The available incentives and rebate programs available to landlords and homebuilders include the Federal Energy Policy Act Tax Incentives whereby this act of Federal Energy Policy Act 2005, presents the inducements of tax for both acquiring and installing competent energy productions in building. This proceed comprises of credits to builders and customers for green structure schemes, enhancements of energy economy home and solar energy organizations (Internal Revenue Service Treasury and IRS Provide Guidance on Energy Credit to Home Builders). On the national Ratings Certifications and Standards, the recognized national ratings, standards systems and certifications of green building can be exceptional gear for regions for employment when coming up with own residential curriculums for green building. There can be customization of national programs in accordance to the differences of the region while giving provision of approval framework on which counties can come up with their own advancement of green building. Therefore there is a widespread network which has provided allowance to the national programs to bring together case studies and al1 the best information practices from all through the U. S (EIA Analysis of 10% renewable Portfolio Standard). There are a number of green building ratings, certifications and standard programs which are countrywide well known and may be given a priority to come up with programs of green building. They include, LEED for homes which is a USGBC with a mission of advancing the revolution of the market of the environment which is constructs, increases and supervises the LEED for the rating systems of homes which were put into action in 2005 and gave provision to a tool for certifying homes that are given a design in order to be energy, water and efficient of resources and built with the health of future occupants being considered. There is also the Centre for Communities by Design whereby the American Institute of Architects (AIA) Centre for Communities by Design does provide support to the societies on sustainable planning through its curriculum of Sustainable Design Assistance Team. SDAT’s undertaking is to provide methodological support in order to hold up communities come up with the vision and the construction for a sustainable future (EIA Analysis of 10% renewable Portfolio Standard). Conclusion The discussion in the paper was based on the green building products and their sustainability of Construction. It seems that, in many cases, the best alternative of a design for interior surrounding quality gives a determination on the excellence of the general atmosphere. Therefore the elimination of air contamination in the indoor will be determined by the durability of the building material which will hence need lower quantities and less toxic chemicals for the maintenance and renovation (Levin Best Sustainable Indoor Air Quality Practices in Commercial Buildings). The paper focused on the implementation and exploration of the green products for construction. There is also the evaluation of the greenness of construction materials which can be evaluated in different ways including valuing the durability, stability, strength and speed of the materials (Levin Building Design and Material Selection). The greenness of products is judged from the way a product or a material reduces its demand for landfills especially the cement company Ceratech in the U. S which makes use of recycled fly ash to manufacture Redimax cement. There are also energy policy acts which are featured on the paper which focus on means of saving the energy (EIA Analysis of 10% renewable Portfolio Standard).

Ugenics Revisited - Genetic Engineering Essay Example | Topics and Well Written Essays - 1000 words

Ugenics Revisited - Genetic Engineering - Essay Example Initially Galton presented the eugenics concept but later many of the scientists worked on it just because of its importance. Like many other unique concepts, eugenics also faced criticism for many other expert scientists and public. At the top of the list, the critics claim the concept and practices of eugenics as unethical and immoral practice for the society. According to their opinion, the practices of eugenics are misused and misunderstood by different people. In addition to these opinions, many other expert scientists are of the opinion that the eugenics practices may give rise to many of the genetically diseases. These diseases are severe and thus cause problems in the entire future generation of the mating people. Due to the increase in the likelihood of these diseases caused by eugenics practices, there is a possibility that the gene variation may get disturbed. The concept of natural selection and genetic engineering is same i.e. the acquiring of the most desired set of traits and characteristics. The only difference is that natural selection is a nature’s ultimate process while the genetic engineering is an optional and artificial process, which anyone can choose on his own opinion (Bradshaw, 2006). For this reason, it is said that selective breeding is different from the natural breeding, though the basic aim or purpose is same behind both these tools or we can say practices. Genetic engineering is very vast field as it includes many of the gene mutations e.g. a human gene inserted in the goat or sheep, a monkey or frog gene inserted in the shrubs and herbs, a spider gene inserted in the goat and a tree gene inserted in the banana fruit. All of these gene mutations come under the head of genetic engineering, which is different from natural selection in this regard. In addition to this genetic engineering can benefit many other are as of life e.g. the growth of such crops, which do not need fertilizers and can bear the heat of

Expander in a cryogenic air separation plant Essay

Expander in a cryogenic air separation plant - Essay Example Ameen argues that â€Å"expanders are used to expand various gases efficiently from high to low pressures to obtain refrigeration† (Ameen 2006 p. 142). Jumonville asserts that in spite of variations in specific processes, â€Å"almost all turboexpanders are used to remove energy from a gas stream, thereby producing power and cooling the gas† (Jumonville 2010 p. 148). In the process of expanding high pressure gas across the turbine, the extraction of most of the gas’s energy potential occurs (Gopalakrishnan & Hardeveld n.d; Mokhatab & Poe 2012). The energy extracted is then transmitted to the shaft and the compressor (Bloch 2006). Consequently, an enormous reduction of pressure in the gas occurs. This consequential fall in pressure together with efficient energy extraction creates refrigeration, which is essential for cryogenic processing of gas (Sapali 2009). Therefore, the use of expanders in a cryogenic plant is to expand high pressure gas thereby leading to te mperature fall. This decline in temperature results into refrigeration, which is essential for liquefaction of gases in a cryogenic plant (Finley 2013; Mokhatab & Poe 2012). Jumonville (2010) argues that â€Å"in most applications, the turboexpander normally runs faster and operates with colder temperatures than any other equipment in the plant† (Jumonville 2010 p.147). The turbine Expanders converts the cryogenic fluid stream hydraulic energy into electric energy (Habets & Kimmel 1999). The expander used in a cryogenic plant is usually associated with numerous benefits. The use expanders in cryogenic plants ensures optimum efficiency, reduces operation cost and also offer reliable and strength augmentation (Kerry 2010). The cryogenic turbine expanders’ efficiency (thermodynamic efficiency) can be observed by obtaining the difference in enthalpy at the inlet and the exit. For an upward flow expander, the pressure of the fluid is reduced continuously from

Scientific Revolution Research Paper Example | Topics and Well Written Essays - 1250 words

Scientific Revolution - Research Paper Example Therefore, the important figures of the development of scientific thinking appear to be the colleagues, who worked on common range of problems and were guided by the same set of rules. The detailed analysis of scientific history and philosophy found an extremely distorted and romanticized picture of the actual situation. It turned out that the history of science was not as straightforward as it had been represented before. Despite the technological successes, the science not necessarily brings us to more accurate description of the reality. The most famous representative of such views was an American physicist and historian of science Thomas Kuhn. The current paper makes an attempt to analyze Copernicus’ discoveries from the position of Kuhn’s theory and his concept of â€Å"scientific revolution†. We will also try to find the gaps in the theory to see if the claim for the universalism of his paradigm is legitimate. Kuhn’s interest in the development of sc ientific theories and scientific revolutions grew out from the consideration of the fundamental differences between social and natural sciences. During his investigations, Kuhn became convinced that, in historical perspective, the development of science is far from smoothness and uniqueness. ... The paradigm is as essential for science in terms of observation and experiment. Allegiance to the certain paradigm is a crucial condition of any serious scientific affair. Science cannot observe and recognize the diversity of a particular phenomenon, because it is not able to conduct all possible experiments and perform all laboratory and clinical tests. In this respect, the scientist has to reduce the studied problem to the working volume. His choice of the set of methodological tools and ideas will be dictated by the system of beliefs of the paradigm he belongs to (Marcum 61). When most of the scientific community accepts a paradigm, it becomes mandatory guide. Once the paradigm is taken, it grows as a powerful catalyst for scientific progress. Kuhn called this stage â€Å"normal science† (Marcum 59). Most of the scientists are engaged in normal science all the time, and that is why this particular part of scientific activity has become a synonymous of science in general. N ormal science is based on the assumption that the scientific community knows what the Universe is. While the existence of the paradigm is taken for granted, only the problems for which the solution can be assumed are considered legitimate. The latter guarantees the quick success of normal science. In such circumstances, the scientific community restraints and suppresses any novelty, because innovations are harmful to the main duty of the community. Paradigm determines the field of solved questions, imposes acceptable methods, and set of standard solutions. Normal science solves the problems, but produces a little new (Marcum 60). At the certain stages of development of science paradigm becomes a conceptual â€Å"straitjacket†

New York Times Article Review SEE below instructiuon Essay

New York Times Article Review SEE below instructiuon - Essay Example In case the price tag is approved by Washington, the carbon content of fuel will become as important as the fuel cost and may even define the fuel cost. The result of this policy will be the competitive capacity of alternative energies, such as wind, sunlight, uranium, corn stalks and trash or natural gas. It would also be possible to start using the so called â€Å"carbon-negative† fuels, taking carbon dioxide out of the atmosphere. The Congress should introduce a special tax or a cap-of-trade system for industries producing fuels. The estimations show that at $50 per metric ton the cost of a kilowatt-hour produced by coal will go from about 5.7 cents to 10 cents. When carbon dioxide costs $25 a ton, wind power will become competitive. Solar power is very expensive now, but the cap-of-trade system making coal fuel equal or even higher in price, solar power gets â€Å"a much larger chance to be relevant†. The carbon calculus concerns not only electricity but also ethanol, called â€Å"closet carbon†. There are possibilities to reduce greenhouse-emissions producing ethanol from trash through a newly-elaborated thermochemical method, proposed by Range Fuels of Denver. Nowadays we use corn ethanol, made using natural gas and coals, containing carbon, and sugar-cane ethanol, resulting in 10% as much CO2. Another approach, being tested in Arizona, is to fertilize algae with carbon dioxide captured from the atmosphere. Scientists even propose carbon-negative products, such as synthesis gas made from biomass, with resulting carbon dioxide being captured chemically. New approaches are sought for in architecture. Today building sites are evaluated for solar orientation and prevailing winds, the possibility to use the existing mass of hillsides and the ambient temperature of the dirt, etc. Carbon dioxide emissions can be reduced in the process of produce of various goods for mass consum ption. The problem is that the new technologies

'Alternative dispute resolution is at the heart of today's civil Essay

'Alternative dispute resolution is at the heart of today's civil justice system, and any unjustified failure to give proper - Essay Example Early 1990s had been witnessing delays in the conduct of litigation in courts exacerbated due to complex procedures and interlocutory battles entailing heavy costs to the parties and the state exchequer as well. As stated by the English Centre for Effective Dispute Resolution (CEDR), British commerce can achieve cost savings of over ? 1 billion by avoiding time spent by the management, spoilt relationships, lost productivity and legal fees.1 Mediation method already has helped save about ? 6.3 billion since 1990.2 In a classical case decided in 2007 involving a claim of just ? 6,000, parties are reported to have spent nearly ? 100,000 as litigation costs. 3 Perceptions about mediation are still mixed as revealed by a survey of the Ministry of Justice in 2007. For 38 % of the respondents, mediation had resulted in cost savings and for 29 %, costs had increased. Those who had settled cases through mediation informed of cost savings except for 7 % of them for whom costs had increased. F or those whose cases could not be settled through mediation, 45 % of them stated cost increases, 19 % cost savings and 28 % did not see any difference in costs.4 Sequel to Lord Woolf’s report, the U.K. Government made it a condition as far as possible to provide for ADR in all government contractual disputes arising out of procurement contracts. 5 As a result, ADR was resorted to in 336 cases out of which 241 were settled with a resultant cost savings of ? 120.7 million. 6 in Royal Bank of Scotland v Secretary of State for Defence, the successful defendant was refused costs as it had not opted for ADR in line with the above said ADR pledge by the Government.7 An audit report of 2007 stated that non-availing of mediation in family disputes entailed additional cost of ? 74 million through legal aid i.e average legal cost for a non-mediated case amounted to ? 1,682 as against ? 752 for a mediated case. 8 Warren K. Wrinkler Chief Justice of Ontario notes with caution that mediati on if not successful ends up as an additional layer in litigation costs. 9 Time efficiency is another factor apart from cost factor. According to a report of the CEDR, in England 75 % of their cases were settled instantly (same day). 10 Mediated family disputes cases are settled faster at 110 days than non-mediated cases which take 435 days to settle. 11 Regardless of cost effectiveness and time efficiency, flexibility available in mediation towards mutually consensual resolution is absent in court led litigation. The English Alder Hey case that involved more than 1000 claims is a classic example of successful mediation that resulted in apology and erection of permanent memorial for the children whose organs had been withheld by the hospital. ADR provides for not only procedural flexibility but also of flexibility of outcome.12 Mediation offers larger number of remedies that include apology, explanation, enduring relationships, and undertaking by one party an obligation without any legal compulsion. 13 In order to have an effective mediation system, the 2008 EU Directive applicable for cross-border disputes states that member states should have legislation that ensures mediation that guarantees a predictable legal framework, provides for flexibility in procedures and ensures autonomy of parties. Besides, the mediation should be conducted in an effective, impartial and competent manner.14 The EU directive adds that it can be applied to internal mediation of the

Recycled Rubber Tyres as Aggregate in Concrete Essay

Recycled Rubber Tyres as Aggregate in Concrete - Essay Example The paper tells that the ability to change the levels of consumption in the UK is one which is essential to the needs to create a sustainable world and to alter the pollutants which are coming from different resources. A technology which is being created is with the use of recycled rubber tyres. There is the option of allowing this to work as an aggregate in concrete, specifically to begin changing the consumption in the UK and to begin lowering the number of toxins with the tyre production that occurs every year. While there is a large amount of consumption and changes with the tyres, there is also a question of whether the aggregate in the concrete is able to create the same substance and material responses as other forms of technology for concrete. This is able to alter and change the way in which the aggregate can be used while determining if the tyres can be recycled into a different substance for other needs. The first question which is associated with the recycled rubber parti cles is based on the understanding of cement paste and how it responds and reacts to the rubber tyre particles being added as a part of it. In a study of Segre Joekes, there was a modification to the cement by adding in rubber tyre powder to the aggregate. The study looked at the cement paste and the way that the surface began to change after a period of 20 minutes. The substance was examined in terms of absorption, density, flexural strength, compressive strength, abrasion resistance, elasticity and fracture energy measurements. The measurement then looked at the level of Sodium Hydroxide (NaOH) with the rubber. It was found that the rubber not only assisted with the mix of the materials in the cement but also increased the level of flexibility, durability, toughness and compressive strength. The conclusion was not only with the improvement of quality with the cement. It was noted that by using the rubber tyres as a part of the cement, different formats for roads and other road con struction areas could be used. The substance which was created from the recycled rubber tyres is one which is not as course, meaning that the use on road construction can help with more durability and sustainability with the recycled rubber (Segre, Joekes, 2000: 1421). The overall changes which were made with the concrete also refer to the rubber tyres changing the properties of the cement to create different levels of substance to be used in different areas. The association with tyres is one which is able to automatically change and assist with the overall needs and properties for strength, specifically with roads and areas which have continuous use and fluctuation. The changes with the cement also show that the use of magnesium oxychloride, a natural property found in rubber, is able to provide more functioning for the cement. This particular substance is able to work to bind the concrete mixtures in a way that improves the strength and durability of the substance. The rubberized concrete not only has the ability to directly impact and improves the concrete which is used. The magnesium oxychloride as a binding substance can help in changing the way in which concrete is used and allows the mixture to provide even more solutions to the substance. The substance differs with the types of tyres which are used, amount that is mixed with the concrete and is dependent on factors such as unit weight, air content and slump. Incorporating these into the mixture is then noted as essential for creating the correct mixture and alternatives with the rubber tyres and concrete mix that is used (Siddique, Naik, 2004: 563). 2.2 Compressive Strength The additional alternatives which are a part of the rubber tyres used in aggregate

Economic evaluation (comparing scenarios) Assignment

Economic evaluation (comparing scenarios) - Assignment Example In the current society, it is considered to be an analytical tool that focuses on managing issues ascribed to uncertainty. Base Case: In the case that financial resources amounting to 1029.8 dollars, are used to solve challenges ascribed to acquisition of PEP, an incremental value of 258.6 dollars would be spend to cater for improving the quality of life leading to 21.418 quality life added year. However, the value of QALY would reduce to 21.399 if only 771.2 dollars are spent to solve HIV challenges without PEP. Worst Case: In the case that an amount of 1098.5 dollars is directed towards solving HIV issues by use of PEP, the QALY would reduce to 15.958 with an incremental cost of 1033.7 dollars. However, if the challenges associated with HIV are solved by investing 62.2 dollars, there would not be incremental costs with an increased QALY of 15.993. Best Case: 2614.6 dollars is directed towards purchasing PEP to solve HIV challenges the QALY would increase to 36.488, with no increased incremental. However, if other methods rather than PEP is used, the costs would rise to 9046.8 dollars with an incremental value of 6432.2 dollars with a relatively lower QALY value

Does creativity in its many forms relieve stress Essay

Does creativity in its many forms relieve stress - Essay Example lessness, Decreased sexual drive, Loss of appetite, Anxiety, Depression, Outbursts of anger. Long terms effects are more dangerous can be in the form of : Chronic head ache, Mood swings, Anxiety disorder, Substance abuse, Memory disturbances, Heart attack and strokes due increased blood pressure, sugar and cholesterol, Weight loss, Exacerbation of allergies including asthma, Irritable Bowel disease, Ischemic Bowel disease like Crohn's disease, Decreased sexual drive, sleeplessness.( Beware! Stress Could Cause Serious Long-Term Effects) The outcome of stress can be either a positive or a negative product depending on how the person deals with it and responds to the situation he's in. If negativity is adopted depression and failure are the end results expected. It is even proven medically how stress can reduce the immunity and a person can be more susceptible to diseases ranging from simple cases as flues and complicated cases such as cancer. On the other hand if a positive attitude is taken creativity can produce wonderful establishments. Stress this unconscious habit, can be dealt with usually in two ways; one is that stressed people repress it into their deep inner feelings which is definitely not healthy i.e. becoming victims, or they express their anger on a person present at the wrong time and wrong place. "Victims internalize their anger and bullies externalize it."(Pragito). Stress management can be through various techniques. Exercise and hobbies are a way of expressing the stress, some people even keep a journal in order to record any stressful event they pass through in order to put it behind their back and try to forget about it, once written it is forgotten. Hobbies such as writing, singing, listening to calm music, dancing and meditation -which is becoming popular nowadays in terms of spirituality building a balance between the body and the mind (Anna)- in other words any creativity form is a live illustration of stress relievers. Many studies indicate how lower stress levels are associated with a higher creativity level, even at the level of elementary school children where this can be a grand step to help future generations to have a lower stress level than present nowadays through creative thinking skills development (Bonita, 1). Creativity in order to be effective can be put into five steps: (Paul) 1. Preparation of information at hand or digging up new data to help in dealing with a problem causing the stress at hand 2. Incubation of the issue and investigating it thoroughly, 3. Enlightenment, which comes at directly or at an unknown moment. 4. Evaluation the solution that evolved and examining it carefully to ensure this is what is really needed. 5. Implementation of the proposal attained from the proceeding steps and putting it in operating action. Some organizations adopted the TQM Total Quality Management approach to decrease the stress levels present in its firms and become more productive in quality values too.

Establishing the Academic Performance of Veterans in the Us Colleges Essay Example for Free

Establishing the Academic Performance of Veterans in the Us Colleges Essay The word veteran comes from Latin word, vetus which means old. It’s used to mean a person who has experience or has served for a long time in the armed forces. Though sometime it may be used to even include those still working in the armed forces (Howe 23). In some countries holidays dubbed Veterans Day have been celebrated to honor the veterans. After World War 2 veteran groups like the veterans of foreign wars and even the American legion pushed for the enactment of the GI bill which has ensured that veterans access free or subsidized education and health care (Howe 23). Objectives †¢ To determine the level of academic performance of veterans in the US colleges. †¢ To understand the reasons why veterans decide to go back to college. †¢ To comprehend the effect of being a veteran on academic performance. †¢ To classify the academic performance of the veterans i. e excellent, moderate e. t. c. Justification Frances claims that the Vietnam veterans, who were on duty between 1956 and 1975, were psychologically devastated and bitter (45) and addicted to drugs (46). They include the people who had an uphill task readjusting to the normal society life, in the US history context (47). Several movies e. g. Hi mom (1970), 1971’s hard ride and Marvel Comic’s movie The Punisher among others have constantly shown that the experience at the Vietnam war for example was so devastating (Jay 23). This warrants a study that probes to know if the government’s efforts to take the veterans back to college is the most appropriate measure. The results will boost the morale of the veterans. The researcher hypothesis will be a Null hypothesis-There is no relationship between high academic performance and being a veteran. It will be assumed that the respondents exam result will be a true reflection of their academic capability and that past exam marks achieved were not characterized by any irregularities. Literature review A number of recent studies keep pointing at the fact that those combat veterans who have PTSD have exhibited memory lapse. According to Nash (112) and Andrew (99), other psychological dimensions including intellectual capacity, veterans with PTSD have been ok just like other non-veterans. According to the newly signed GI bill by the USA president George W. Bush on 30th June 2008, all American young veterans are assured of a chance to obtain a college degree or university degree free of charge (Montreal Gazette). An example of the serious attention being given to this sector is Horatio Alger association’s commitment in 2005 to distribute 10 million dollars to those veterans who fought wars in Iraq and Afghanistan. This bill was signed in recognition of the Jewish War Veterans. It was also signed in order to review the educational benefits attached to the military, navy or the air force from which a majority of the veterans emanate and which have been outpaced by the standards of living. The bill has been timely because it eliminates the stringent procedures and replaces them with a minimum of three years of active service to the nation in the military, navy, air force or any other troops like reservists or guardsmen. The veteran benefits are to those who have participated actively in long term state duties and have received an honorary discharge from duty e. g. the American Soldiers who went to fight the war in Iraq and made it back home (National Guard). The financial Aid office and the department of veteran affairs in the US which is based at Ivy Tech in Southern Indiana have been very instrumental in promoting education for the veterans. According to a recent survey by Minnesota state colleges and universities (2007), 80% of National Guard soldiers from Minnesota completing their overseas deployment, said they were keen on beginning or returning to complete their higher education (Karmaz 345). These veterans returning from military duty abroad face numerous challenges i. e. personal, relationship, employment matters and education as they struggle to return their lives to normal civilians (Nash 116). As the president of Las Positas College DeRionne Pollard puts it in her welcome note, the veterans have made an astonishing difference in the lives of their countrymen and women. The peace and freedom that is enjoyed by the US for example as she puts it, is as a result of the tiresome work and a strong sense of duty exhibited by the veterans in their various state assigned duties (Andrews 34). This study will therefore be seeking to establish the general academic performance of veterans and the factors responsible for the standards In veterans elementary public school in Chula Vista that caters for approximately 542 students from grade k-6 in 2007 had an adequate yearly progress of 845 surpassing the 800 mark set by the state of California. Sounds impressive but, how about other schools/colleges? (Neubauer Diane 376) Methodology This study will utilize both quantitative and qualitative methods. In quantitative method, the academic records of the veteran students will be analyzed; their performance will then be compared to the other non-veteran students in the same setting. A test will also be set and administered to all respondents. The research will utilize several resources including stationery, analyzing computers where data is entered and comparison charts and graphs produced. Qualitative method will also be used be used to generate the opinions of the respondents. Unstructured questionnaires will be used to generate this information. All qualitative information of similar nature will be grouped together i. e. information coding. The coded information will then be organized in the form of matrix and then conclusions drawn from the data, E. g. Oral examinations on general topics can also be posed, the respondent’s answers will then be checked for content and their levels of understanding understood. Data analysis The quantitative data on the performance of the subjects will be compared with that of a control reference population of students with the same characteristic but who are not veterans. The qualitative information will also be translated into percentages of the subject who prefer to go back to college for several reasons. The qualitative information will then be used to explain the performance of the veterans quantitatively. For example, if a majority of veterans go back to college because they want to gain knowledge or because they want to develop new careers and assist their families, then we would rightly conclude that the high performance by the same people is purely because of self motivation and not because of the harsh conditions they faced in service for the nation. Results According to (Willenz 56), a case study done on 204 veterans in Michigan, it was found that 60% of the respondents performed well in college at the beginning but later their performance depreciated and they eventually underperformed, with approximately 20% of them dropping out. Of those who dropped out, 90% of them were not going for counseling sessions. The results clearly show that though many veterans want to go back to college, their past experiences plays a major role in what becomes of that decision. However there is a serious need for the veterans to be attached to counselors or psychologists whose therapies should make them fit to go back to college and stay on course to achieve desirable results. Veterans most of the time have suffered severe consequences of war and therefore as a show of appreciation for the sacrifices they made the government through a specifically set financial scheme offers to take them back to school or if they accidentally passed on in line of duty, their family members are given the benefits. These benefits have been characterized with a lot of procedural technicalities that have denied genuine candidates their dues. The most common scenario is that of veterans living in conditions of poverty and engaged in a lot of legal battles with the state in an attempt to prove that they are worth compensating. For the veterans to become normal civilians after participating in military wars there is need for a carefully structured educative system that re- integrates them into the society through counseling and other methods. Recommendations The veterans occupy an integral part of any society. Their contribution in safeguarding the interests of their nation calls for more than is currently being offered even by the US. Young veterans only should have the option of going back to college as compulsory especially if they had not gone to college. But aged ones should be given an opportunity to access the compensation in terms of finances and be able to do what they like with it. The Compensation for duties discharged should not only be education grants but should also include job placements. Because of their selfless actions it would be prudent for the concerned governments to increase the compensations given to those who have been disabled in the line of duty. The duration of service should be a determining factor for compensation.

Sex Education in Secondary Schools Essay Example for Free

Sex Education in Secondary Schools Essay Background The health and bright future of every adolescent is shadowed by risk of sexually transmitted diseases, unintended pregnancy and even abortion, that will enable them to reach their goals in life. Research shows that one youth is infected with HIV every hour of everyday, while 5% increase in teenage birthrate, 40.5 births per 100 young woman ages 15-19 (Hamilton et.al.2009).This mind numbing fact, is pointed to the aggressiveness, curiosity and misguidance of teens about the issues of sexuality. In a Christian country, like Philippines, these issues are taken with great care and fragility, hence, according to Wagoner (2001), this are public issues that should be treated with rights, respect and responsibility instead of fear, denial and blame. The youth have the right to accurate information, deserving of respect and do have an obligation to act responsibly. Ignorance regarding this is a crucial matter that has an easy remedy: educate the youth and give hope for a more informed tomorrow (Leavitt, 2009). Because like what Wagoner (2001) said, â€Å"By this we could protect their (youth) health and their lives.† Sex education on the other hand, according to Kirby (2002) and Alford (2003), it teaches about abstinence as the best method of avoiding STDs and unintended pregnancy through contraception, it talks about interpersonal and communication skills which help young people explore their own values, goals and options, a prevention program that will affect multiple behavior and achieve positive health impacts. As support to the global call of sex education, Representative Lagman (2008) said that Reproductive Health Bill was formulated by the congress here in the Philippines, that promotes information on access to both natural and modern family planning method, which are medically safe and illegal permissible and assures an enabling environment where women and couples have the freedom and choice on the mode of planning their family while strengthening PopCom in educating the youth. For this reason, the researchers would like to expose the importance and effects of sex education program in the learning of teens and in the preservation of the country as a whole at the same time, assist and guide the youth to be responsible not only in their decision but more importantly to their judgment as to what Villegas (2009) said, â€Å"The only thing that will bring things to order is time.† Statement of the Problem 1. What are the importance of integrating sex education in the learning of teenagers? 2. What are the effects of integrating sex education in the learning and intellectual growth of teens? 3. What would be the impacts of sex education in social, spiritual and sexual development of teens? Statement of the Objectives 1. To instill among the youth the importance of sex education. 2.

Scope and Limitations of the Study The study is only limited on the importance and effects of integrating sex education on the learning of teenagers in the secondary level and it’s feasible contribution towards nation building and global prosperity. It was conducted at La Filipina National High School, La Filipina, Tagum City, from February to March 2010 and was participated by 100 respondents consisting of 20 teachers (five every year level) and 80 students (20 per year level). Significance of the Study For the youth: The main purpose of this study is to provide information about sex education, its importance and effects to the academic performance of teens towards self-preservation and to showcase a wide array of choices to help live a healthy and productive life that would ensure active participation of youth in nation building and global development in the future. For the parents: The significance of the study is to help them to realized their big and vital duty to guide the youth and inculcate among them the values they should bear in mind to lighten their path towards a brighter future. For the teachers: The relevance of this research is to equip them with the right concept in providing not only quality education but also how education be used in fighting ignorance as core cause of deemed tomorrow. For the community: The importance of this research is to give the correct and clear meaning of sex education, as well as, its objectives to awaken the community of its advantage to address the increasing population growth and lessen if may not eradicate sexually transmitted diseases infected and to bring back youth closer to the Almighty creator. Definition of Terms Sex Education -is a program that teaches about abstinence and about using condoms and contraception to avoid STDs and unintended pregnancy, thus develop interpersonal and communication skills. Abstinence -refraining from doing sexual activity before marriage. Sexually Transmitted Disease -or STD is a disease transferred sexually like AIDS, HIV and many more. Morality-is a conduct or attitude judgment from moral standpoint. Unintended Pregnancy -is similar to unwanted pregnancy. Contraception is the process of controlling birth. Reproductive Health Bill -is a bill in the congress that: †¢ Aims to control rapid population growth, unwanted pregnancy and abortion. †¢ Provide the public contraceptives and intensive discussions about issues of sexuality. Chapter II Review of Related Literature The question of weather sex education should be taught in school took along debate up to this very moment inspite with the fact given by the University of the Philippines Population Institute (UPPI) and Demographic Research and Development Foundation, restated by Dr. Singson (2010), 26 percent of our Filipino youth nation wide from 15 to 25 admitted to have a premarital sex experience, and worst is 38 percent of youth are already in live-in arrangement. The Philippine Situationer dated 2009, added that about 1.8m boys and 670,000 girls aging 15-24 have pre-marital relations already, 766 HIV seropositive children and youth, and got pregnant between 18-19 years old that contribute to 400,000 indused abortion annually thus infecting the quality of education gained by youth that unable them to be productive. Wagoner (2001), emphasized sexuality education is not an either/ or proposition, it’s the reality young people needed and deserved. He further stretched, that he will always believe that the better way is to try rights, respect and responsibility to give young people tools and, more they will make safe and responsible decision out of it. Sex education on the other hand, according to Alford (2001), teaches abstinence as the best method to avoid HIV, unintended pregnancy and abortion, it provides value based education, shows variety of choices in the manner of living, accurate information about the reality of sexual issues, teaches proper usage of contraceptive materials to serve as protection, and preaches religious values to give youth opportunity to explore their own. Macken in 2006 also mentioned the programs efficacy in preventing HIV and other STD. Leavitt (2009), determined ignorance regard safe sex is a crucial matter with an easy remedy: educate the youth and give them hope for an informed tomorrow. However, Anderson (1993) President of Probe Ministries International, viewed that the problem is not lack of education, but lack of moral instruction, according to him, young people needed information about sex, but it must be placed in moral context. He further said that we should provide youth with biblical principles and moral leadership in dissecting this issues. In contrary, researchers of Advocates of Youth (2009), stated that sex education clearly shows programs that do not encourage teens to start sexual intercourse, do not increase even the frequency, instead decrease the number of sexual partners which was supported by Kirby (2001) and Alford (2003) and in Mckeon’s research in 2006. That is why Rep. Edcel C. Lagman (2008), author of the RH Bill of the Philippines, wishes to proved that, (1) Information and access to natural and modern family planning (2) Maternal, infant and child health and nutrition (3) Promotion of breast feeding (4) Prevention of abortion and management of post-abortion complications (5) Adolescent and youth health (6) Prevention and management of reproductive tract infections, HIV/AIDS and STDs (7) Elimination of violence against women (8) Counseling on sexuality and sexual and reproductive health (9) Treatment of breast and reproductive tract cancers (10) Male involvement and participation in RH; (11) Prevention and treatment of infertility and (12) RH education for the youth strengthen PopCom, are vital to promote a well oriented community that shall raised the level of public awareness on the urgent need to protect and promote reproductive health and rights. The study of Kohler and et al. (2008) said, that its not harmful to teach teens about birth control in addition to abstinence. Mauluer et al. (2009) also added, that sex education greatly boost the delay if not decreased the intercourse participation rate. Dr. Markham (2009), told that we need to develop prevention programs that address the needs of the students who are not yet sexually active to promote skills and attitude to help them wait until they are older to have sex, we need to provide knowledge of condom and other contraceptive materials to the sexuality active and to give accurate and factual information and services related to STD’s through education. Albert (2010) said, that no one suggests to set guidelines alone will work at all time for all people, that it is important that we will have a large portfolio and effective options, and that is what education could cater. Effects In the academic and intellectual growth. Supposed sex education is effectively implemented. The Millennium Development Goal or MDG #2, which seeks to achieve universal primary education will be attained, for the program will help youth to proceed and finish proper education, thus, creating them employable, said Virola (2009). Senderowitz in 2000 analyzed that, learning about the reproductive health is pout of the larger developmental process as child become adult. He further stated, this developed self-esteem, a sense of hope and goals for the future, and respect for others. Pick de Weiss et al. (1998), said that the study of Institute Mexicano de Investigacion de Familia y Poblacion or (IMIFP) and the New York- based Population Council showed that the course can increase student’s knowledge on how to incorporate sex in the larger context of life. Delano in 2000, Association for Reproductive and Family Health Executive Director, revealed that this assessment could provoke life-building skills like negotiation skills, values classification, refusal skills, decision- making and goal setting. She further emphasized, that this skill will enable youth to cope with the demands and challenges of growing up and self management. Moreover, Mahler (1896) agreed, because according to her this will help youth develop and practice decision- making skills, because sex education is not just about sex, but it facilitates self-esteem and the feeling that you have options and you are in control of things. Nguer in 1999 added, that this education allows youth to be more mature and to be able and face some of life’s problems, it was also supported by Vincent et al. (1987), that the program is focused to improve decision-making skills, interpersonal communication skills, self-esteem and balancing of personal values, which is parallel to what Bailie said in 1995, thus, expressed a strong desire for better education and parents should be part of it. In the study of Cairns (1990), he found out the self-esteem and locus of control were associated with benefits in a single sex school than a mixed- sex environment. Mallam (1993) also revealed that this kind of curriculum showed attitudes toward academic subjects. Impacts on the Social, Sexual and Spiritual development †¢ Social advancements Since social aspect is defined as the relationship and communication into someone or to the community, as a whole. Integrating sex education according to Kirby, restated by Leavitt (2009), that this program can effectively reduced the number of sexual partners. Sex education had been successful in various settings. Sendorovitz (2000), written that the program include peer-based approaches and media activities to reach people thus young people can comfortably and safely explore issues and concerns to practice safer sexual behaviors. Whitaker (2000), reported that its effects were safer behavior and strong ties in the family, school and church. Nguer of 2000 also emphasized, that this also involves respect and responsibility. Since the values of respect for women by men and violence were instill in their minds. Bailie (1995) also added that the opportunity for individual counseling with someone they trust like their parents and friends are also given importance. According to Dohoney (2007) they (youth) learned about how to say no to sex which is a clear result of having a sound judgment. †¢ Sexual improvements Sexual activities are both natural to human and animals yet for human it’s more sacred and treated with respect. Kirby (2007) found that 30 percent of this program lessens sex frequency and 60 percent reduced unprotected sex. Kohler et al. (2008) said that teens who received sex education were 60 percent was likely to report becoming pregnant. According to Grunseit (1997) this activity delayed the inset of sexual activity, reduced the number of sexual partners and decrease unplanned pregnancy and STD rates and a significant reduction in sexual risk-taking. Dohoney (2007) said, that receiving sex education before the first sexual activity has the positive outcome. According to Lagman (2008) this reduces abortion rates by as much as 85 percent that negates the need to legalize abortion. He added that the United Nation and countries with sex education stated, that the youth understand the proper sexual values, early initiation is delayed, multiple sex partners is avoided, spread of STDs is prevented. In conclusion he said this raise the level of public awareness on the urgent need to protect and promote reproductive health and rights. †¢ Spiritual enlightenment When temptation comes let GOD be your guide. 1 Corinthian 10:13 said, â€Å"There hath no temptations taken you but such as in common man: but GOD is faithful, who will not suffer you to be tempted. â€Å"It is clearly stated that with intimate relation with GOD no temptation will ever shake the foundation of our very soul which is faith. According to Leavitt, the mission can only be achieved by offering a personal relationship with Jesus Christ as the best way to live a sexually pure life. In addition, Sanches (2010) said, that if you’re sexually pure because you are educated, you will avoid things that may tempt you to do pre-marital sex, and aborting baby. You won’t feel cheap like used rags, because you believe in God and with it the pursuit for sexually pure is easy. Chapter III Methodology Locale of the Study The location of the study may be classified into two: First, was at La Filipina National High School, La Filipina, Tagum City and the second was at the University of Southeastern Philippines,Tagum-Mabini Campus, Apokon, Tagum City. The former, includes the gathering of data through survey and latter, signifies the interpretation, analysis and making of the entire research study. Procedure After deciding the topic, researches of the anything related to it followed. From these researches, the researchers come up to a survey questionnaire form making it accurate to answer the problems and objectives of the study. The survey was made last March 2, 2010 at La Filipina National High School which was participated by 20 students and 5 teachers every year level summed up to 100 respondents. In every year level, the focus of the survey was only on the first section class having 20 respondents each, composed of 10 boys and 10 girls selected on random order. For the teachers, there were no specific guidelines on choosing who will answer the survey questionnaire. The respondents were chosen for they will be the one who will be affected directly for what so ever the result may be. Interpretation and analysis of the data gathered followed to form the summary, conclusions and recommendations.

Normal Approximation in R-code

Normal Approximation in R-code Normal approximation using R-code Abstract The purpose of this research is to determine when it is more desirable to approximate a discrete distribution with a normal distribution. Particularly, it is more convenient to replace the binomial distribution with the normal when certain conditions are met. Remember, though, that the binomial distribution is discrete, while the normal distribution is continuous. The aim of this study is also to have an overview on how normal distribution can also be concerned and applicable in the approximation of Poisson distribution. The common reason for these phenomenon depends on the notion of a sampling distribution. I also provide an overview on how Binomial probabilities can be easily calculated by using a very straightforward formula to find the binomial coefficient. Unfortunately, due to the factorials in the formula, it can easily lead into computational difficulties with the binomial formula. The solution is that normal approximation allows us to bypass any of these problems. Introduction The shape of the binomial distribution changes considerably according to its parameters, n and p. If the parameter p, the probability of â€Å"success† (or a defective item or a failure) in a single experimental, is sufficiently small (or if q = 1 – p is adequately small), the distribution is usually asymmetrical. Alternatively, if p is sufficiently close enough to 0.5 and n is sufficiently large, the binomial distribution can be approximated using the normal distribution. Under these conditions the binomial distribution is approximately symmetrical and inclines toward a bell shape. A binomial distribution with very small p (or p very close to 1) can be approximated by a normal distribution if n is very large. If n is large enough, sometimes both the normal approximation and the Poisson approximation are applicable. In that case, use of the normal approximation is generally preferable since it allows easy calculation of cumulative probabilities using tables or other tec hnology. When dealing with extremely large samples, it becomes very tedious to calculate certain probabilities. In such circumstances, using the normal distribution to approximate the exact probabilities of success is more applicable or otherwise it would have been achieved through laborious computations. For n sufficiently large (say n > 20) and p not too close to zero or 1 (say 0.05 To find the binomial probabilities, this can be used as follows: If X ~ binomial (n,p) where n > 20 and 0.05 So is approximately N(0,1). R programming will be used for calculating probabilities associated with the binomial, Poisson, and normal distributions. Using R code, it will enable me to test the input and model the output in terms of graph. The system requirement for R is to be provided an operating system platform to be able to perform any calculation. Firstly, we are going to proceed by considering the conditions under which the discrete distribution inclines towards a normal distribution. Generating a set of the discrete distribution so that it inclines towards a bell shape. Or simply using R by just specifying the size needed. And lastly compare the generated distribution with the target normal distribution Normal approximation of binomial probabilities Let X ~ BINOM(100, 0.4). Using R to compute Q = P(35 X ≠¤ 45) = P(35.5 X ≠¤ 45.5): > diff(pbinom(c(45,35), 100, .4)) [1] -0.6894402 Whether it is for theoretical or practical purposes, Using Central Limit Theorem is more convenient to approximate the binomial probabilities. When n is large and (np/q, nq/p) > 3, where q = 1 – p The CLT states that, for situations where n is large, Y ~ BINOM(n, p) is approximately NORM(ÃŽ ¼ = np, ÏÆ' = [np(1 – p)]1/2). Hence, using the first expression Q = P(35 X ≠¤ 45) The approximation results as follows: l ÃŽ ¦(1.0206) – ÃŽ ¦(–1.0206) = 0.6926 Correction for continuity adjustment will be used in order for a continuous distribution to approximate a discrete. Recall that a random variable can take all real values within a range or interval while a discrete random variable can take on only specified values. Thus, using the normal distribution to approximate the binomial, more precise approximations of the probabilities are obtained. After applying the continuity correction to Q = P(35.5 X ≠¤ 45.5), it results to: ÃŽ ¦(1.1227) – ÃŽ ¦(–0.91856) = 0.6900 We can verify the calculation using R, > pnorm(c(1.1227))-pnorm(c(-0.91856)) [1] 0.6900547 Below an alternate R code is used to plot and illustrate the normal approximation to binomial. Let X ~ BINOM(100, l4) and P(35 45) > pbinom(45, 100, .4) pbinom(35, 100, .4) [1] 0.6894402 # Normal approximation > pnorm(5/sqrt(24)) pnorm(-5/sqrt(24)) [1] 0.6925658 # Applying Continuity Correction > pnorm(5.5/sqrt(24)) pnorm(-4.5/sqrt(24)) [1] 0.6900506 x1=36:45 x2= c(25:35, 46:55) x1x2= seq(25, 55, by=.01) plot(x1x2, dnorm(x1x2, 40, sqrt(24)), type=l, xlab=x, ylab=Binomial Probability) lines(x2, dbinom(x2, 100, .4), type=h, col=2) lines(x1, dbinom(x1, 100, .4), type=h, lwd=2) Poisson approximation of binomial probabilities For situations in which p is very small with large n, the Poisson distribution can be used as an approximation to the binomial distribution. The larger the n and the smaller the p, the better is the approximation. The following formula for the Poisson model is used to approximate the binomial probabilities: A Poisson approximation can be used when n is large (n>50) and p is small (p Then X~Po(np) approximately. AN EXAMPLE The probability of a person will develop an infection even after taking a vaccine that was supposed to prevent the infection is 0.03. In a simple random sample of 200 people in a community who get vaccinated, what is the probability that six or fewer person will be infected? Solution: Let X be the random variable of the number of people being infected. X follows a binomial probability distribution with n=200 and p= 0.03. The probability of having six or less people getting infected is P (X ≠¤ 6 ) = The probability is 0.6063. Calculation can be verified using R as > sum(dbinom(0:6, 200, 0.03)) [1] 0.6063152 Or otherwise, > pbinom(6, 200, .03) [1] 0.6063152 In order to avoid such tedious calculation by hand, Poisson distribution or a normal distribution can be used to approximate the binomial probability. Poisson approximation to the binomial distribution To use Poisson distribution as an approximation to the binomial probabilities, we can consider that the random variable X follows a Poisson distribution with rate ÃŽ »=np= (200) (0.03) = 6. Now, we can calculate the probability of having six or fewer infections as P (X ≠¤ 6) = The results turns out to be similar as the one that has been obtained using the binomial distribution. Calculation can be verified using R, > ppois(6, lambda = 6) [1] 0.6063028 It can be clearly seen that the Poisson approximation is very close to the exact probability. The same probability can be calculated using the normal approximation. Since binomial distribution is for a discrete random variable and normal distribution for continuous, continuity correction is needed when using a normal distribution as an approximation to a discrete distribution. For large n with np>5 and nq>5, a binomial random variable X with X∠¼Bin(n,p) can be approximated by a normal distribution with mean = np and variance = npq. i.e. X∠¼N(6,5.82). The probability that there will be six or fewer cases of these incidences: P (X≠¤6) = P (z ≠¤ ) As it was mentioned earlier, correction for continuity adjustment is needed. So, the above expression become P (X≠¤6) = P (z ≠¤ ) = P (z ≠¤ ) = P (z ≠¤ ) Using R, the probability which is 0.5821 can be obtained: > pnorm(0.2072) [1] 0.5820732 It can be noted that the approximation used is close to the exact probability 0.6063. However, the Poisson distribution gives better approximation. But for larger sample sizes, where n is closer to 300, the normal approximation is as good as the Poisson approximation. The normal approximation to the Poisson distribution The normal distribution can also be used as an approximation to the Poisson distribution whenever the parameter ÃŽ » is large When ÃŽ » is large (say ÃŽ »>15), the normal distribution can be used as an approximation where X~N(ÃŽ », ÃŽ ») Here also a continuity correction is needed, since a continuous distribution is used to approximate a discrete one. Example A radioactive disintegration gives counts that follow a Poisson distribution with a mean count of 25 per second. Find probability that in a one-second interval the count is between 23 and 27 inclusive. Solution: Let X be the radioactive count in one-second interval, X~Po(25) Using normal approximation, X~N(25,25) P(23≠¤x≠¤27) =P(22.5 =P ( ) =P (-0.5 =0.383 (3 d.p) Using R: > pnorm(c(0.5))-pnorm(c(-0.5)) [1] 0.3829249 In this study it has been concluded that when using the normal distribution to approximate the binomial distribution, a more accurate approximations was obtained. Moreover, it turns out that as n gets larger, the Binomial distribution looks increasingly like the Normal distribution. The normal approximation to the binomial distribution is, in fact, a special case of a more general phenomenon. The importance of employing a correction for continuity adjustment has also been investigated. It has also been viewed that using R programming, more accurate outcome of the distribution are obtained. Furthermore a number of examples has also been analyzed in order to have a better perspective on the normal approximation. Using normal distribution as an approximation can be useful, however if these conditions are not met then the approximation may not be that good in estimating the probabilities.
