Ligament Injuries Essay -- Health Injured Ligaments Essays

Ligament Injuries The volleyball match has been going on for over an hour. Both teams have been trading points and side-outs. The ball is set high outside so that the big outside hitter can put the ball away. She comes in hard, plants, leaps into the air and smashes the ball down the line in a twisting motion. As she lands on her right leg, a POP is heard and down she goes. What has just happened is occurring more and more often in athletics, the athlete has just torn the anterior cruciate ligament (ACL). In this paper I will describe ACL, how it is injured and diagnosed, how it be repaired and what is being done to prevent ACL injuries. The Anterior Cruciate Ligament (ACL) is one of the two cruciate ligaments of the knee, the other being the Posterior Cruciate Ligament (PCL). These ligaments are the stabilizers of the knee. The ACL is a strip of fibery tissue, which is located deep inside the knee joint. It runs from the posterior side of the femur (thigh bone) to the anterior side of the tibia (shin bone) deep inside of the knee. The ligament is a broad, thick cord the size of a person's index finger. It has long collagen strands woven together in a fashion that permits forces of up to 500 pounds to be exerted. The function of the ACL is to prevent the tibia from moving in front of the knee and femur. The ACL also prevents hyperextension (or extreme stretching of the knee backward) and helps to prevent rotation of the tibia. The amount of knee ligament injuries have been on the rise in recent years. Over the last 15 years, ankle sprains have decreased by 86% and tibia fractures by 88%, but knee ligament injuries have increased by 172%. The injury usually occurs in either a slow twisting fall, a sudden hyperextension, or a sudden hyperflexion as when landing from jumping. When the injury occurs the athlete usually hears a "pop" and they will have immediate swelling of the knee. When the person tries to put weight on the leg it will feel like the knee isn't underneath the athlete. With most injuries the type of movement will help to determine the injury: "I twisted to the right." etc. When ACL injuries occur there is a "popping" sound at the time of injury and swelling within six hours. An experienced clinician can diagnose an ACL tear with relative accuracy by a manual examination. X-ray examination and ... ...t of stress. A knee bend resistive exercise program done by The United States Ski Team has resulted in an 80% decline in serious knee injuries. The program uses a single stance one-third knee bend going from 30 to 80 degrees at a steady rate for three minutes, working up to five minutes on each leg. Sport band (elastic cord) can be used to increase resistance when initial levels are achieved. The anterior cruciate ligament is the main guide to knee stabilization. Fortunately injuries to the ACL are now much more treatable and athletes are returning to performance at a greater rate. All athletes need to be aware of the risk of ACL injuries but they also need to know if it does happen, it's not the end of their athletic career.

Is biological pest control better than chemical pest control?

Food is vital for humans to survive, the population of the world is immense as it approaches 6 billion and all these humans need to be fed on a continual basis. Therefore, a large quantity of food needs to be produced rapidly and on a very large scale. Generally farmers across the western world do produce food very quickly and efficiently and there tends to be a surplus of food, whereas, in less developed countries they have a shortage of food. Due to the size of the world's population and it's high levels of demand for food farmers are unable to leave crops alone and let them grow naturally. Read this  Respiratory Activity For example, one-third of the crops that are grown worldwide are spoiled by pests, animals particularly insects and many plants. Certain types of crops grow better in certain set conditions and there are many different factors which effect the crop yield. Crops grow by photosynthesis, the environmental factors affecting the rate of photosynthesis, are light intensity, concentration of carbon dioxide in the air, and the surrounding temperatures. All the requirements for photosynthesis need to be available at a good rate and supply, the light intensity which is usually supplied by the sun needs to be at suitable intensity, which means the crop will only grow certain times of the year due to the amount of light available. The same applies to the concentration of carbon dioxide, which usually does not tend to cause a problem, as there is ample supply of carbon dioxide in the surrounding air, however if it is ever to run low the crops will not grow. The temperature is another factor which has a huge effect on the growth of crops, if the temperature is to get too high this would prevent any growth of the plant as it would not be able to deal with the extreme temperature killing off the chlorophyll that the plant requires to grow. However if the temperature is decreased to a very low temperature this will restrict any growth, as the plant will not be able to function properly. Therefore, all these factors need to be at the correct rate for the crop to be able to grow sufficiently. Many different types of crops such as maize, corn, wheat, rice, fruit and vegetables are grown at different times throughout the year and most farming is usually based on monoculture. Which is where one type of crop is grown in a certain piece of land, this technique of mass production tends to cause many problems and is not as straight forward as it seems. If crops are growing extremely well and conditions are correct and all the crops have all their requirements at the right rate and intensity there is still one other factor which would still prevent a perfect yield from being produced which are known as pests. These pests still destroy all crop yields, by destroying the crop its self and restricting growth in certain ways. When crops are grown they are just like plants in that they compete for mineral ions, water from the soil and light, however when crops are grown using the monoculture method there usually isn't a problem because it's the same crop being grown and so the conditions can be controlled. However, the problems that do arise is that if there is a large concentration of the same crop in one area and they are all in close proximity to each other then there is the potential of the crop being infected by diseases, fungi, unwanted plants and insects which will then lead to the rapid destruction of large areas of the crop. There are a number of different pests, for example, insects, fungi and weeds that effect individual crops in different ways; like insects, fungi and weeds. Weeds are plants that grow in places we do not want them to grow and there optimum growth occurs in ground disturbed by human activity. They compete with cultivated plants for space, water and minerals. Worldwide, about 10% of crop yield are lost because of weed growth. Weeds tend to come in different sizes and they can be long and the same length as the crops, which means their roots are able to reach deep into the ground and take the nutrients, they require leaving many shortages for the crops. Also weeds can sometimes have broad leafs that cover the crops and so take all the sunlight and restrict the amount of sunlight reaching the crop. The competition between the crops and weed, which is organisms of different species, is known as interspecific competition. Occasionally you may come across weeds that are very small and do not do any real harm to the crops. The insect pests work in many different ways, each kind of plant has its own species of aphids, and these little creatures have small mouthparts, which they use to suck sap from plants. The loss of sap can be harmful to the plant in many ways in that, it can cause leaves to curl up and become distorted. The leaves are the place where photosynthesis takes place; the curled up leaf leaves the plant unable to photosynthesise efficiently and so can leave the plant stunted. Another way in which aphids can effect crops are, that as the aphids suck in the sap if that crop was diseased they could pick up the disease or virus and then go suck on another plant which would then pass the disease or virus on, which would spread the disease to many plants, any organism which spreads disease or viruses from host to host is known as a vector. Also if the aphids take in to much sap they tend to secrete it through their abdomens, this is usually a sticky honey dew which forms a sticky droplet which attracts ants, which then attack the crop even further. So altogether there are a number of ways in which crops are prevented from being grown. The ways in which these pests can be controlled and crops can be grown without too many problems is that we can put into the environment a chemical substance that kills the pest, which is called pesticides, or we can put into the environment another organism, which kills the pest, which is known as biological control. A pesticide is any substance or mixture of substances intended for preventing, destroying, or repelling any pests. Chemical control is the use of pesticides. Insects, which eat crops, can be killed with insecticides. Fungi, which grow on crops, are controlled with fungicides. Weeds, which compete with crop plants for water, light and minerals, can be controlled with herbicides; pesticides are usually applied as pellets, powders or sprays. Many different chemical substances are used as pesticides; there are contact pesticides, systemic pesticides and residual pesticides. The contact pesticides are used as spray as they are sprayed straight on to the crop where the pests are living and as the contact insecticides spray comes in contact with the insect, the insect tends to absorb it in through its gas-exchange pores, the spiracles, along its body. This is where it attacks the insects and poisons them. The same process occurs with contact herbicides and fungicides the surface of the plant absorbs the poison through, and so the poison then attacks it there. This method is not very expensive however they need to be reapplied continuously as there are always pests, which are missed out, and the affect of it does not last very long. Systemic pesticides work in a similar way as they are sprayed straight on to the crop where the leaves and surface of the plant absorbs it in and so it is transported all around the plant. Therefore, whenever a sap-sucking insect comes along it sucks the poison into its body, and this eventually results in the killing of the creature. This method for systemic insecticides is very effective because the spray does not have to come into contact with the insect so it only attacks the insects that attack the crops. Systemic herbicides are also quite effective in that they are able to be sprayed onto the surface of the leaf where they get absorbed and then have that poison transported all along the weed killing off the tissue and even reach the roots. Residual pesticides can also be quite effective, as they are also sprayed directly on to the soil and instead of attacking the actual insect or weed they attack any insect egg and larvae, and weed seedling as they germinate. All these methods are used for chemical pest control; chemical pest control is very effective in that this is the most popular method in the UK for farming large number of crops, to provide the large population of the UK. However even though chemical pest control is very effective and is very popular there are a number of disadvantages of using chemical pesticides. Firstly, chemical pest controls involve many chemicals that can be very dangerous if they are not monitored correctly. Therefore, chemical pest controls must be safe for farmers to use and must not damage the environment. To provide this there must be continual testing and development carried out on all pesticides. This can be very expensive and this expense will be passed onto the farmer in the form of the pesticide costing a huge amount of money. This expense is taken by the farmer on the premise that it will assist in the good growth of his crops, however, the disadvantage being that it may not work at all! It is also known that pesticides damage the environment a great deal, Pesticides can badly affect wildlife through changes in the food web, direct and indirect poisoning. And their harmful effects may show up in animals, which have no direct relationship to the original pest. In that in the 1950's many of the pesticide used did a lot of damage to the environment especially one DDT (dichlorodiphenyltrichloroethane). It was used to kill insects, however people didn't realise that it is a persistent insecticide, which means it doesn't break down but remains in the body of insects and the soil. So whenever a bird or other organisms ate the insects they ate the DDT too. And so the DDT stayed in their bodies and just began to accumulate. Also as well as being persistent it was also non-specific as most pesticides are. This means that it not only harms the insect it's meant to but also harms other living things. For example in the 1960s, the gannet population in Quebec began to shrink. The shells of the gannets' eggs were too thin to protect the embryos. Once the egg had been examined they realised DDT was the culprit. Because there where large concentration of DDT in the birds because of all the pests they had consumed which had been sprayed with it. Many other birds such as ospreys, eagles and peregrine falcons also had been affected greatly and populations of those birds had declined. Also all the chemical sprays that are sprayed into the air will have a great effect on the atmosphere. So many pesticides harm the environment a great deal, even though many tests are done before hand. Pesticides also change wildlife habitat, for example if a herbicide was put down on certain plants or vegetation, animals that depend on that piece of vegetation find it difficult to live any longer and so slowly will begin to die out, and so if they begin to die out then the population of their predator that relies on that particular creature, will begin to decrease. Another problem, that that may arise is if a particular pesticide is used a lot the pest may eventually become resistant to it. The pesticide no longer kills the pest and so a new one has to be developed at all times which results in more resources and cash flow being ploughed into developing and testing. Also once the pesticides are applied, they can be used up quickly and if it rains they sometimes need to be reapplied which takes much time and effort because special clothing and safety measures need to be carried out each time. The most important disadvantage of using chemical pesticides are that the crops that have been produced using pesticides are now covered with chemicals which we will now eat and which can be very harmful for us. Another major harm to humans is to farmers, who are using the pesticides and are in contact with it on a continual basis and it has led to them becoming extremely ill, for example, in parts of the UK, farmers and their families are being diagnosed with illnesses, which are associated with pesticide poisoning. Such conditions as multiple sclerosis that are occurring in many of the farmers, especially in the cases where they use sheep dipping as part of their work. Also in less developed countries the farmers are effected a lot more because they do not have all the specially designed clothing which they require and so in places like Malaysia and Sri Lanka, 7 to 15 per cent of farmers experience poisoning at least once in their lives. The advantages of using pesticides are that all these chemicals do produce the maximum amount of food, which is very cheap for the consumer, because the farmers are able to produce on a mass scale, using the chemicals to make sure they have a high-quality crop yield. Also pesticides work very fast and most of the time instantaneously, once applied to the ground. With pesticides you usually have a guarantee that they will work and be extremely effective, and solve the pest problem. Chemical pest control is one way to control pests even though there are a number of disadvantages, however the other way to stop pests from destroying crops are by biological control. Biological control is not using chemicals but the use of a specially chosen living organism to control particular pests; the chosen organism may be a predator, parasite or disease, which will attack the harmful insect. It is a form of manipulating nature to increase a desired effect. Examples of this are usually A bluebird: it eats insects to prevent damage to trees and gardens. They are found throughout the United States, UK and Canada A ladybird beetle: it eats small soft insects, which prevents damage to fruit and crops. They are found throughout North America. A garden spider: consumes insects with wings by catching them in a sticky web that it spins. Usually found in America and UK. Biological control is usually done in three ways known as classical biological control, conservation and augmentation, these are three ways to use these natural enemies against unwanted insect pest population. Classical biological control is to import which involves travelling to the country or area from which a newly introduced pest originated and returning with some of the natural anomies that attacked it and kept it from being a pest there. New pests are constantly arriving accidentally or intentionally. Sometimes they survive. When they come, their enemies are left behind. If they become a pest, introducing some of their natural enemies can be an important way to reduce the amount of harm they can do. The second method is conservation; conservation of natural enemies is an important part in any biological control effort. This involves identifying any factors that limit the effectiveness of a particular natural enemy and changing them to help the beneficial species. Conservation of natural enemies involves either reducing factors, which interfere with the natural enemies, or providing needed resources that help natural enemies. The final method is augmentation; augmentation is a method of increasing the population of a natural enemy, which attacks a pest. This can be done by mass producing a pest in a laboratory and releasing it into the field at the proper time. Another method of augmentation is breeding a better natural enemy, which can attack or find its prey more effectively. Mass rearing can be released at special times when the pest is most susceptible and natural enemies are not yet present, or they can be released in such large numbers that few pests go untouched by their enemies. The augmentation method relies upon continual human management and does not provide a permanent solution unlike the importation or conservation approaches may. There is also another way in which pests can be controlled using the biological control method, which is known as Biochemical pesticides these are natural occurring substances, which are safe. This is because most plants and animals produce chemicals that can be used, as pesticides, the oils and seeds are usually the substances, which can be pesticides. For example many insects produce chemical substances called Pheromones, which attract the opposite sex. Synthesised pheromones are sometimes used to attract pest insects into traps. The traps are usually sticky which hold the insects and so enables you to get rid of them by killing off the insects. Another method of biological control is crop rotation this helps to discourage pests. Since different pests affect different crops, crop rotation can be very effective method of pest control. Using crop rotation means that there is high possibility of pests dying out before the same plant is grown on the soil again. In many cases, removing their preferred food and shelter can control pest populations. Examples of crop rotation are below. Year1: potatoes – may be affected by potato cyst eelworm Year 2: cabbage – may be affected by clubroot and brassica cyst eelworm Year3: beans – root nodule bacteria improve soil nitrate supply All these methods of biological controls can be used however they also have many disadvantages to them, just as chemical control biological control takes more intensive management and planning. It can take more time; require more record keeping, more patience, and sometimes more education or training. Because a successful use of biological control requires a greater understanding of the biology of both the pest and its enemies. Also often the result of using biological control is not as dramatic or quick as the results of pesticide use, which can react very quickly. The aim is not to wipe out the pest because this could be counter-productive. If the pest were reduced to such an extent that it no longer provided enough food for the predator, then the predator in its turn would be wiped out. The few remaining pest could then increase their population rapidly, in the absence of the controlling agent. The ideal situation is where the controlling agent and the pest exist in balance with one another, but at a level where the pest has no major affect on the crop yield. Even though biological control has disadvantages it also has many advantages. Biological control, overall is a far safer method as it reduces the environmental and public safety hazards of chemicals, as the food we are eating is not covered with poisonous sprays and the air is not being polluted by sprays which we breath in that can be quite harmful to us. Also biological control is cheaper for the farmer to use overall because like pesticides they don't have to be reapplied continuously, once they have been introduced they begin to work and consume the pest, so together its cheaper and less time consuming and easier to apply. Another advantage of biological control is that the pest are less likely to become resistant to the control organism then they are to pesticides, which means unlike pesticides a new pesticide doesn't have to be developed on a regular basis. Also unlike most insecticides biological controls are often very specific for a particular pest. The biological and chemical controls of pests work very well individually however the two can be used together, this is known as integrated control. This method can be very successful as was shown in Indonesia in 1970's, when they began to use large numbers of pesticides to control the pests to produce high yields strains of rice. There where a lot of brown planthopper pests, and so farmers found them selves spraying up to 8 times a season, to get rid of the pests however it was later discovered that the insecticide was the problem of the large number of these pests. This is because the sprays had wiped out all the natural predators of the pest, particularly the spiders and yet only had a limited effect on the pest its self. So it was here that the integrated control was introduced. With integrated control the use of pesticides is always the last resort with the minimum amount used. This then prevents pests and enables large healthy yields of crops without using too many pesticides, which have many disadvantages. However using integrated pest management is not always easy, the technique requires time, knowledge and dedication on the part of the farmer. Overall when using pest controls there are a number of factors to consider, to get maximum effect and sustain pest control. The important factors to consider are how efficient each method is at controlling the pest, the cost, damage that might be caused to the environment, and possible health hazards. When considering how efficient each method is at controlling pests I think both are quite good in their own way in that biological control is aimed at the one pest whereas chemical pesticides tend to infect all insects and plants that they are sprayed on. However at the same time chemical works a lot faster and targets the problem more efficiently whereas biological takes a lot more time to establish its self to the environment and take effect. The cost is a lot cheaper for the biological, because even though it costs a lot to research and develop to make sure everything is correct and working well, it doesn't cost the farmers a lot to get the method started, and once it has been applied it doesn't have to be re-applied continuously like chemical control. Also with chemical control there is the extra cost on top to develop and test the chemical product, also new chemical products need to be developed continuously at all times because pests become resistant to them quickly unlike biological control. Even though biological requires a lot of development, training and testing it only has to be done once and then there usually is a result, and doesn't have to be repeated over and over again to develop new pesticides like chemical control. Damage that might be caused to the environment is mostly caused by chemical control because there are a number of pollutants sprayed into the air, which infect the atmosphere, and there are a lot of chemicals going in to the soils, which also damages the soil. Also if pesticides are persistent a large concentration can be built up in different animals, which can cause problems and be dangerous to those animals. Additionally pesticides are not selective and harm creatures that don't need to be infected; also a number of habitats can be destroyed when certain plants are killed. Whereas biological don't have any environmental effects and so biological controls would be a better one to use. Possible health hazards are that chemical controls can be dangerous to the people who have to apply them to the ground and also the food we eat has absorbed the spray and so they can infect us and harm our bodies. However biological controls do not have any health hazards, therefore, are very safe and is the better one to use. In addition in the developed world we have become increasingly concerned about the long-term effects that chemical pesticides and herbicides may have on us as we eat our well-sprayed food. We have also become progressively greener over recent years, with more and more people expressing concern over the future of the earth and our effect on it. Substituting biological control for chemical intervention therefore seems like a very good idea. The developing world cannot yet afford such concerns the main struggle for many developing nations is to be able to feed all their hungry mouths. But in these countries too the cost of chemical control and the increasing resistance of pests to the expensive chemicals are adding another powerful voice to the arguments in favour of biological control as an integrated part of pest management. So overall the one I think is best and has least problems and safest to use is the biological controls.

The Things they Carried by Tim O´Brien - 1948 Words

When people think of war what comes to mind is death, torture, and destruction. War instills fear since everyone dreads involvement in the ordeal (Mazlish 10). The experience of war leaves people with physical and psychological scars. Tim Obrien in â€Å"The Things they Carried† brings to light the tribulations faced by the soldiers in their quest to restore peace. He asserts, ‘war is hell (Brien 8).’This is an exhilarating story that brings to light the fact that, despite their participation in the war, soldiers are still human. Stanley Kubrick echoes Obrien’s sentiments in his award winning film the Full Metal Jacket. Both highlight the ugly truths of war as full of cruelties and absurdities. The experience of war for the soldiers shows that they are still human with feelings and emotions (Mazlish 11). For some, their emotions grow stronger while others undergo mental anguish and breakdowns, but whatever the case nobody is ever the same again. In this perspective, it is captivating to note that these two masterpieces reflect on the US Vietnamese war. They both try to analyze the effects of war on the soldiers and the struggles they underwent in their quest to bring tranquility. In both cases, it is disheartening to understand that they succeed in bringing physical peace at the expense of their emotional peace.

Bill Cosby quotes, â€Å"sex education may be a good idea in the schools, but I do not believe that kids should be given homework.† Although Cosby makes light of the situation, educating the youth about sex and sexuality is imperative to providing a holistic educational experience.

Report On Business Sustainability Practice †MyAssignmenthelp.com

Question: Discuss about the Report On Business Sustainability Practice. Answer: Introduction Corporate social responsibly, often used in short CSR is a corporate initiative to take responsibility from the companys part that focuses on contributing to the improvement of the society, environment and social well-being (Tuyen 2014). It is also coined as corporate citizenship and does not aim to immediate financial profit; however, it is the way of the corporate companies to promote environmental change and social positivity (Tuyen 2014). The purpose of this report is to provide some recommendations to the Sunselect property group for sustainable business practices. The Sunselect property group is known for residential building construction for over fifty years. The report will mainly talk about the way and usefulness of the energy efficiency, waste minimization and water consumption reduction in the constructional procedure. Energy Efficient Constructional Project The Sunselect Property Group (SPG) is a property developer company based in Sydney, New South Wales, Australia. The company is reputed for developing commercial and residential building complexes for over fifty years. In order to improve the companys CSR profile, the company aims at building a low-rise but high-density housing complex named as The Greenfield Development. This project will promote the sustainable living and business sustainability of the company. The residential buildings and complexes of Australia has been consuming and emitting heat energy increasingly throughout the last two decades. Energy emission from the residential sector will be increased to fifty-six percent by 2020 from 1990 (Saman 2013). The heat waves frequency is increasing in Australia due to overuse of electronics devices, which is generated from housing sector (Saman 2013). As there is abundance in cheap energy all over the world, the housing constructions and designs do not consider the energy efficiency factor. The priority should be on building energy efficient housing complexes, which will reduce the amount of heat from the environment and eventually that will contribute to the society in large. The energy efficiency process in the buildings is one of the best ways to reduce heat energy from the environment and maintain sustainability. It would also be helpful especially in the context of global warming where the total amount of heat of the earth is increasing. The construction authority should look into the matter seriously. Waste Minimization in the Constructional Process Waste minimization is another process that could be applied in the constructional process as business sustainability method. The constructional waste, which includes small portion of bricks, cement dust and other hazardous materials, can be found on-site and off-site (Emeraldinsight.com 2017). The waste generated from the constructional process is very harmful and dangerous for the environment. The sustainable development should focus on waste management, as the overall process of construction is not at all environment friendly. The waste management should proceed through reduction and recycling of the constructional waste (Emeraldinsight.com 2017). The construction authority should use non-hazardous materials in the construction process, which have low amount of waste production and it will be recycled and reused. The waste management should be done properly at the constructional site as it could reduce maximum amount of environmental pollution and maintain sustainability. However, it is not always done properly due to lack of awareness among the authority and labors. The constructional authorities should emphasize on the waste management strategies to improve their CSR profile. Water Consumption Reduction Thirdly, it is recommended that water consumption in the constructional process should be reduced and constructional authorities should follow strategies that can restore water from misuse. At the constructional sites, water is used for many activities like washing various substances, cleaning, and plastering and at cabins for temporary accommodation (Greenconstructionboard.org 2017). As water is used some general purpose like washing, cleaning and mixing it is very difficult to identify the process of wasting water. It is suggested to the authority to create awareness among labors not to misuse water. They should tell the laborers that not to waste water. The purpose of using water should be specific and clear. Some study has shown that wasting water depends upon the behavioral pattern of the members at the constructional site. Recommendation The sustainable building industry focuses on constructing net zero energy and energy efficient housing complexes, which can reduce heat waves. It is recommended to use energy efficient appliances and gas boosted solar hot water system at each home to reduce heat and energy. The residents could use solar electricity, which also emit less heat frequency in the environment (Harris and McCaffer 2013). It is suggested to provide an energy meter to the residents of the housing complex that will show the total amount of used energy per day (Ma et al., 2012). The constructional authority could replace the hazardous substances with non-hazardous material or at least materials that are less hazardous for waste management in the constructional process. There could be a storeroom at the constructional site to dump the constructional waste and consequently it can be used for recycling. Materials for recycling should be chosen from the constructional waste dump (Chudley and Greeno 2013). The constructional authority could think of to use alternative water resources like rainwater and to serve this purpose they can use rainwater-harvesting method (Greenconstructionboard.org 2017). It is the responsibility of the authority to think about how the water is used and in what way it can be saved. Even they can apply some technology that can automatically reduce water usage at the constructional site. For example, the Willmott Dixon has introduced a new technology that can obsolete water in flushing (Greenconstructionboard.org 2017). This technology is known as eco-cube. Some other constructional companies employ waterless urinals and self-closing tap that can reduce water consumption from the constructional site (Ijirset.com 2017). Conclusion It can be concluded that the Sunselect Property Group could follow the above-mentioned strategies to improve the sustainability and the CSR profile of the company. The reduction of heat emission from the building, waste management in the constructional process and water consumption reduction in the constructional procedure will help the environment for reducing pollution as well. The company should focus on this instead of immediate business profit as every corporate company has some social and environmental responsibility to perform. However, if the company could improve its CSR profile, it will directly contribute to the well-being of the society as people could live in a healthy environment.

It All Begins With Attitude Essays - Social Psychology, Attitude

It All Begins With Attitude IT ALL BEGINS WITH ATTITUDE from the seminar BREAKING THROUGH LIFE'S BOUNDARIES by Pat Spithill Seminar Leader * Author * Keynote Speaker (C) Copyright, 1989, Pat Spithill P.O. Box 505 * Hutchins, Texas 75141 214-225-8051 This material may not be reproduced or altered without written permission of the author and copyright holder. The Importance of Attitude The Merriam-Webster Dictionary defines the word "attitude" as "a mental position or feeling with regard to an object." The mental positions or feelings are our thoughts, beliefs and opinions. The object is life. In other words, attitudes encompass all of the thoughts, beliefs and opinions which people have about their lives. Over 2500 years ago, Buddha said, "All that we are is the result of what we have thought; it is founded on our thoughts. If a man speaks or acts with pure thought, happiness follows him, like a shadow that never leaves him." Buddha also said, "It is a man's own mind - not his enemy or his foe that lures him into evil ways." A person's attitude, what Buddha was speaking of, is the very foundation on which his or her life's experience has been, is, and will be built. Every part of reality is the result of a person's attitudes. In simple terms, our attitudes reflect what we expect from life. This shouldn't be confused with what we want, dream or hope for. No one wants to be unhappy, lead a boring life or look back over the years with remorse and regret. Yet, so often rather than expecting the best life has to offer, people expect much the opposite. They expect problems and get problems; expect disappointments and are disappointed; expect to fail and then, rather than experience the desired success, they fail. If attitudes are the mental expectations about jobs, relationships, financial status and so on, then these very powerful thoughts must be the elements which set the course for our lives and destiny. It isn't life's circumstances which create the attitudes; it's the attitudes which create life's circumstances. When people change their expectations and attitudes, then their lives must surely change as well. I know a gentleman who, in the late 1960's, worked as a repossessor of logging trucks. If you will, create a mental image of a person who walks up to burly truck drivers and says, "I have to either have a payment or the keys, whichever you want." I would picture someone about 6'3" and 220 pounds of solid muscle. As it happens, Jim Cathcart is 5'9", rather slender and not the muscular type. People who repossess cars, foreclose homes, or work for collection agencies tend to be negative thinkers. However, one day Jim heard a radio program with a message about the power of positive expectations. He changed his attitudes and began planning for and expecting an exciting success filled future. Today, Jim Cathcart is an internationally recognized leader in the field of sales and management seminars and consulting. Jim has written eight books, is the co-author of Relationship Strategies, an all time top selling audio cassette program from Nightingale-Conant, and is one of the highest paid professionals in his business. And all because he expected to succeed, he expected the best life could provide. This article about building the foundation for your life on the concrete blocks of a positive attitude will cover four things: the source of attitudes; the difference between directive attitudes and reactive attitudes, how the word HALT can help you maintain and strengthen positive attitudes, and specific skills and techniques for building expectations for a wonderful and exciting life. Attitudes - Directive or Reactive Most people fail to ever consciously take control of their lives, living at the mercy of the prevailing winds of fate. Their attitudes are reactive in nature rather than directive. These people constantly respond to changing conditions rather than creating situations which suit their purposes. If you were to lose your job today, how would you react? What emotions would you feel? Would you be angry, incensed, hurt, disappointed? Would you go home, feel terrible and beat-up on yourself for hours on end? A little over a year ago, just before my wonderful wife Jan and I relocated to the Dallas area from Denver, the company for which she worked went through what can only be called disastrous changes. Over the course of four months, the firm laid- off 90% of its work force, approximately 85 people. Due to decreasing revenues, it
