An Experiment to find out how the length of wire effects resistance Essay Example

An Experiment to find out how the length  of wire effects resistance Essay In this experiment we are trying to find out if by changing the length of a piece of wire its affects the resistance of current. I will find this out by having a piece of wood with a piece of wire stretching along the wood. I will have a power box on connected to an ammeter and voltage meter and then these connected to the piece of wire using crocodile clips. The variable Im going to change will be the length of wire. We can have the wire from the length of 1cm up to 100 cms long. We can use the crocodile clips to make the wire long or short. The equipment I will use is:* Crocodile clips* Power Pack* Wires* Variable resister* Ammeter* Voltage Meter* Wood with a piece of wire clipped onto itI chose the equipment I have because I think that it will be the best to use this so it will measure it accurately and give good results. To measure the Variable which Im changing I will have a piece of wood with measurements written onto it so I can use it to mark where I have to put the crocodile clips so it is a accurate measurement. The variable Im trying to measure is the resistance. The resistance is a current that flows through the wire when there is a current running through it, I will have an ammeter and a voltage meter to read the resistance. I will be making my investigation a fair test by using the same equipment each time i.e. the same piece of wood with the measurements on it.I will also wait until the measurements on the ammeter and the voltage meter are not flickering so I can read then and they are still and not in-between numbers, this will hopefully help me get an actuate reading. I will try and do the test for each length four times so I get another actuate reading. There are some things that might make the test go wrong and give me an inaccurate readings, such as if the door is open in one of the four times I do the test, that result might be higher resisentence or lower, the room temperature might change as well during the test but I cant control that. T he only way it could be the same things is if I did the experiment in a small area and I could control the temperature the test was being done in. This is how my experiment will be set up:I predict that the more wire I use on the wood stick, then the more resistance I will get travelling through the wires and the reading on the ammeter will be high for the long lengths and short for the short length of wire. I think this because the more length there is the more energy that will travel through it, then the readings on the ammeter and voltage meter will be high.The variables that could effects the tests are the room temperature, which I cant control. The heat of the power box I can control, by turning the box off at the end of each test and letting it cool down for a bit because other wise I might slow down the energy due to over heating. Another thing that might affect the test is the length of the wire which I connect the circuit together with. I cannot get the wires the same lengt h because I cannot cut the wires so this might affect my results a little bit but not a lot. Another thing I could do to make it a fair test, I could check that the power box, ammeter and voltage meter is working properly each time. One more thing it is important because I dont think you can control this unless you measure it all out.The crocodile clips are wider in length, so when you put them onto the measurements you want, on the wire it is not perfect on the measurements on the wood. So each time you take a result it is either less then what you want or more then you want. The only way you could possible control this is if you measured the width of the crocodile clip and measured the distance form the wire and not then I dont thing you could get it exactly perfect. So one time you do the results you might get the crocodile clip on the right spot and another time you might get it way out of line with right measurements. I think that if you keep to all these and try and control al l of the variables that can effect the investigation then I might get a good set of results that I can use in my graphs etc.I will collect four sets of results that are near each other in some ways like in decimal points if I round them up, this should mean they are near enough right.The measurements I will take are the length of the wire and how it affects the resistance and the voltage against the current; I will show these results in a table and in a graph for each one. When Im doing my test I will make a not of where the slider on the resister is so when I do my test again I can change it or leave it the same. I will do this so I can compare the results for each other set of results and see what ones changes the resistance the most.I found a few problems when I did the test. The first power pack I used didnt work so I had to change it. It was confusing because the wires overlapped but then I found out that u could change the wires round so they were straight and I didnt get mixe d up. I also found that the crocodile clips wouldnt stay on the wire probably, they would slip down the wire and they would not stay on straight so this might have interfered with my results because the measurement wouldnt have been accurate. To find the resistance, I had to use the voltage and divide it by the current (v a = )Length Of Wire (cm)Current (a)Voltage (v)Resistance0 40 cm0.130.584.460 50 cm0.120.625.160 80 cm0.100.757.50 100 cm0.100.800.80The results above are the set from my primarily test. It shows all the results vary, there could be something I have done wrong. The current and voltage are in the same decimal place but the resistance shows they can vary. This might so a variable have changed that I havent controlled. In my set of results from where I do four separate tests for each length I will work out the average from the results.The TestLength (cm)Current (a)Voltage (v)ResistanceAdverae0 40 cm0.080.140.150.350.350.400.321.194.83.33.53.5A= 0.18V= 0.640 50 cm 0.090.130.140.300.350.520.531.213.94.03.84.0A= 0.17V= 0.700 80 cm0.070.100.110.200.500.680.691.292.16.86.36.5A= 0.12V= 0.790 100 cm0.060.100.100.100.920.760.781.300.557.67.87.2A= 011V= 0.85I have done my experiment safely, I have made sure that the wire and power box havent got any other power going into it and I have made sure that I havent over heated the wires so that the wire on the piece of wood hasnt burnt. In the table above it shows my four repeated tests for each length of wire. The results were not all the same but they show that I have done the experiment carefully. I know that I have collected enough results because there is a fair number for each length and I can divide them, (the voltage and current) to get enough answers.I have made changes to my investigation because I have redone my test again, but this time I did it four times instead of three. I made sure it was a fair test by doing everything I said I was going to do in my plan. I tried to make made precise mea surements by trying to get the crocodile clips as close to the measurements on the wood piece as I could. I also made sure the right number on the ammeter came up so its didnt flicker and it stayed on one number for more then one second. I have found out by doing this experiment that there are a lot of variables that could make the results be different then the results if you could control everything that could change the results.On my graphs it shows that if you double the length then you double the resistance, in some cases this will work but in others it doesnt. My plan shows sensible way of testing my prediction because, the line on my graph shows this aswell. The line on my graph goes up in a straight line to show how the length of wire affects the currents resistance. You can use my graph to predict results for similar test like this in the future. My results in my graph show that resistance can be changed by anything that can affect the current or resistance.My perdition was correct because my results show the higher the measurements are then the higher the resistance of the current should be.My experiment was accurate because I made sure that all the things that could affect my investigation I controlled. None of my results were odd really they all made a line that wasnt in a curve so they didnt stand out or nothing. If I did have some odd result I would have got these by making a wrong mistake on one of the test or even the length of the wire could have changed for one test. The most difficult part of the test was recording all the results, because I did four tests for each length then it made it harder for me because I had to wait each time for the power box n wires to cool down, (this was for safety). I could improve my experiment next time to make it more reliable by maybe having more time do it because then I could leave it a certain amount of time each time so that I could have let it cooled down say for 2 minutes after each test, so the temperat ure decreased.If I ever did my test again then I could improve it many ways. I could have more time so I can do it a bit more slowly so I can get accurate result for each test. I could also make sure the wires the same length and this would make it fairer and maybe give me a different set of results that were clear and that had a pattern. I could also make sure that the temperature of the wires and power box etc stayed the same throughout the tests I did. I would start by making sure the crocodile clips were put on the wire with accuracy so they didnt slide up or down the wire when I was making the readings. I would use a different variable that I could place the wire onto that I could also write the measurements like 10 cm and 20 cm onto, I could use a rule instead of writing it onto the wood.My conclusion after I have done this experiment is that a lot of simple things can change the state of resistance everytime you do the test. You would have to have everything clipped to one an other with different variables to make it a really accurate test then you even might have a few things that will make a few odd results on a graph.

Karl Popper and Falsification

Karl Popper and Falsification Free Online Research Papers Sir Karl Popper, challenging the status quo, inspiring generations to ponder on the meaning of science, the methods to find truth, is one of the most influential philosophers of the 20th century. Of particular importance to scientific methods of inquiry is the brawl between the development of theory and the criteria for science. In Popper’s own words, it is in this brawl that Popper decided to â€Å"grapple with the problem: When should a theory be ranked as scientific? or Is there a criterion for the scientific character or status of a theory?† (Popper 1957), p. 1. Born just after the turn of the century in 1902 (my Great Aunt was 4 at the time), in London, England, Popper began grappling with the brawl between â€Å"when is theory scientific† and â€Å"what is the criteria for the scientific character of theory† in the fall of 1919 (p. #). The thing that troubled Popper most he stated is â€Å"When is theory true?† (Popper 1957), p. 1-2). Born from the thing that was troubling Popper most originated his philosophy of Science as Falsification. First, it may be dangerous to proceed any further in this discussion without bringing into light perspectives about the time when Popper toiled on the naissance of falsification. In 1919, when Popper began to labor about potential for truth in theory, social turbulence was epidemic in Europe. The period between 1914 and 1989 can be viewed as a â€Å"protracted European Civil war† (Williams 2005). World War I (WWI) is well underway while communism extends beyond German idealists and the Russian Comintern into Hungary and Italy. Greek forces occupy Turkey’s Aegean coast for territorial ambitions. Over 20 million people are dying of a flu epidemic sweeping across China, Europe, and into the Americas. Social principles shift in the United States with laws prohibiting the sale of alcohol and granting women the right to vote. Social disturbance, disorder is the standard, not the exception of the time when Popper inaugurates a quest to find ‘truth’ in scientific explainadum. Other philosophers of the time endeavor to understand and explain social phenomena during the early 20th century. Max Weber, Karl Marx, Freidrech Engles, Thorstein Ve blen, and George Simmel excavate from all the political revolutions, the social disorder(s) of this period and emerge with capacious explanadum for a multitude of facets addressing social theory. â€Å"Philosophers were accused- rightly, I believe- of philosophizing without knowledge of fact, and their philosophies were described as mere fancies, even imbecile fancies’†(Popper 1952)p. 127). It is with the back drop then a discussion may proceed that recognizes the angst Popper toiled under to emerge with a simply elegant position that science is falsification. What then is falsification? In an attempt to define science from pseudo-science, Popper states that the growth of scientific knowledge begins with an imaginative proposal of hypotheses† (date, p. #). Then, the scientist must search for illustrations or situations that falsify or negate the hypothesis. This search for illustrations or situations that negate the hypothesis is falsification. Pseudo-science is science that does not meet scientific standards (of the period) but does conduct experiments. But what of pseudo-science? When is science the truth? What explains the difference between science and pseudo-science? Popper explains by providing an example. Traditionally, a discipline that conducts pseudo-scientific experiments is astrology. By amassing observations, astrologists produce horoscopes or biographies (Popper 1957). To distinguish science from pseudo-science, the investigator, at this point in the 20th century, could turn to the method and parse out true science from pseudo-science. The use of empirical methods and inductive explanations is the root cause for Popper’s revolt upon the metaphysical reasoning used to explain social behavior (at this time). It is not that astrology is a pseudo-science; astrology is merely a residue of the subject of the investigation (Popper 1952). Disciplines are means of administratively distinguishing the unified systems from which problems may be taught. It is far more important to understanding falsification that â€Å"We are not students of a subject matter but students of problems† (Popper 1952)p. 125). Traditionally, scientists formed hypotheses to explain or rationalize some natural phoneme that they have observed. Popper intends that a hypothesis must predict a phenomenon or behavior and not just offer to explain it. â€Å"I believe that there is not a classic of science, or of mathematics, or indeed a book worth reading that could not be shown, by a skillful application of the technique of language analysis, to be full of meaningless pseudo-propositions† (Popper 1952), p. 130). Popper is positive that each hypothesis has a possible contradiction. This â€Å"sensitiveness to problems† to the extent of having a â€Å"consuming passion for them† fortifies Popper’s revolt against merely accepting plausible and rationalized results of observations. For falsification to take place, the scientist must identify situations that falsify or negate the hypothesis. Finally, after rigorous attempts have been made to find the hypothesis untrue, the scientist may tentatively accept the hypothesis as true. However, if the hypothesis is found untrue, the scientist must reject the hypothesis. Therefore, Popper has set forth not only a definition of a scientific theory, but also an environment wherein scientists may work. Popper intends that a hypothesis must predict a phenomenon or behavior and not just offer to explain it. Therefore, a few statements may be made to expand and sequence the understanding of falsification. These ordered statements are that 1) for scientific discovery to take place, a clear problem statement must be designed, 2) attempts to find this hypothesis untrue must be conducted, 3) when the investigation cannot find the hypothesis untrue at that point then finally 4) the discovery is made regarding prediction of the ori ginal problem. Popper makes it clear that theory cannot be completely explanatory and all inclusive (Klemke et al. 1998). The key characteristic of a theory is falsification in itself. If the possibility for negating the theory does not exist, then the hypothesis is not scientific. When the theory is falsified, the scientific community learns from the experience and knowledge becomes a cumulative contribution among philosophers. Popper provides a service to the scientific community by spawning a means to parse science from pseudo-science more clearly. Popper’s theses in philosophy to include a tenet of falsification caused a tectonic shift in scientific investigation. Responses of rejection from other philosophers poured in regarding Popper’s assertions for the need to falsify. Imre Lakatos, for example, is harsh on Popper. Criticisms include: Lakatos argues that falsifiable already refers to how science is practiced. Lakatos interprets Popper as demanding scientists to specify in advance a crucial experiment (or observation) which can falsify it, and it is pseudoscientific if one refuses to specify such a ‘potential’ falsifier† (Lakatos 1963). â€Å"If so, Popper does not demarcate scientific statements from pseudoscientific ones, but rather scientific method from non-scientific method (Lakatos, p. 1). Lakatos goes onto claim that Popper fails to provide the scientific community with a means for â€Å"rational criticism of consistent conventions† (Lakatos 1963). For Aiken, Popper does not address three different questions: 1)whether historical data can be trusted as evidence for social laws, 2) whether there are verifiable laws of ‘development’†¦for the basis..to predict future events, and 3) whether there can be what may be called laws of ‘unrestrictive scope’ in terms of which all social processes may be explained. (Aiken 1947), p. 147)Clearly from this spurn of remarks from Lakatos, Aiken and others upon Popper’s falsification theses has caused a scientific revolution under the principles set forth by Thomas Kuhn (Kuhn 1996).

Leaders and Potential Leaders Literature review Example | Topics and Well Written Essays - 500 words

Leaders and Potential Leaders - Literature review Example Cultivation was aimed at using one's intellect in doing a job. Emotional and actual advantages were given as the corresponding result. Third, the leader must be prepared to present the plan, to inform the followers of the requirements and to allow the followers to take control of the situation. Examining the Author’s Methods It is contended that the author did not implicitly state the thesis of the article. The statement could actually be simplified. Also, the grammatical structure was incorrect. The sentence started with a second person point of view and then it ended with a third person point of view ( the use of the word you to them). Such kind of mistake could actually disappoint the reader. It has a tendency to take away the reader’s interest. As a result, one may stop reading the article upon noticing the wrong done. Nevertheless, if the one reading is a potential leader, then, there is a possibility that he or she will excuse such error. Moreover, the writer was not able to present adequate ideas to support the thesis. The suggested ways were too general. It could have been specifically enumerated. The writer’s personal experiences were not enough to substantiate the proposed steps of utilization. Nonetheless, the third paragraph provided a logical example.

The Different Types of Leases Research Paper Example | Topics and Well Written Essays - 1500 words - 1

The Different Types of Leases - Research Paper Example This paper illustrates that in order to obtain business equipment and supplies that can shed its effects on the flow of money, one can rely on lease financing as the possible way to straight up capital. Recent surveys prompt that more than 80% of the business organizations in the United States rely on this alternative at minimum one of the equipment acquisitions. It is forecasted that almost 95% would lease in the future. Lease financing is often referred to as â€Å"lease†. It is a contractual agreement involving two parties the lessor and lessee. The lease can be defined as a legal document that must be reviewed by an experienced attorney. The company acts as the lessor grants the individual or group acting as the lessee leasing the product or equipment. The contract assigns the lessee to operate the equipment for some pre-specified time. In the period the lessee is required to make monthly payments to the lessor for providing the opportunity. The lease can be categorized in to the following: lease of finance and lease of operation, sale and leaseback along with direct lease, lease of single investor and leveraged lease, domestic lease and international lease. However, finance lease and operating lease are the most popular leases. A financial lease covers the entire life of the equipment to be leased. A sale and lease can be thought of as one type of financial lease. One can even think of combination lease. This type of lease combines aspects of the popular leases. The effects of the tax can be categorized in the following two ways. The first category is to determine the effects of each flow of cash on taxable income. Rents or another type of fees tend to increase the taxable income while expenditure has the opposite effect. The second category is to compute the amount of the tax to be paid and time when the payment is to be made. After the calculation of the taxable income, the rate of the tax is applied to arrive at the liability. The tax is generally paid in 4 installments. The fourth, sixth, ninth and the twelfth month is regarded as the months of payment for the particular year. The amount of the flows is referred as magnitude.

Situation Background Assessment Recommendation Assignment

Situation Background Assessment Recommendation - Assignment Example There are a number of them. But the best is SBAR (Situation Background Assessment Recommendation), according to most of the healthcare organizations for transfer of information in the correct manner. They are useful in communicating among medical staff, between doctor and patient between nurse and patient etc. The language is clear and simple and is applicable for both written and oral communication. The steps include stating the situation, the circumstances causing the situation, determining the problem and arriving at the best solution. The healthcare organization has their own procedures to fill up forms concerned with the patient's clinical history during the course of their treatment in the unit. That will give clear, concise information about the patient and the type of treatment he gets. However, the accuracy of the record is doubtful. At times the patient would not have given the proper information. It may so happen that the recording may not be proper or legible. Even so clinical record can be considered very valuable in most instances. During verbal communication, there is every chance of data being missed or misunderstood. The reason is that the doctors, nurses and other health personnel etc lack effective communication skill, though they may be good in their own field. The healthcare professionals including nurses have been educated to deal with patients in communic ation, but not among themselves or how to communicate during an emergency. Also, there are no rules for verbal communication, whether direct or through telephone. It is obvious that communication errors may have adverse effects on the patients. It is praiseworthy that various steps have been taken for the improvement of communication among the staff. These will ultimately result in the safety of the patients. According to Dr. Michael Leonard, MD, nurses' communication is descriptive. But that of the physicians is strictly to the point. He feels that SBAR model will nullify the differences in approach and style. It proposes how a nurse should communicate with a doctor. Adopting the SBAR tool has considerably improved patient's safety. It is valuable not only for communication between doctor and nurse but among a number of team members. Let us look at the following instance. One Mr. Joy took his wife to hospital. She had hysterectomy with bowel perforation. An overdose of medicines resulted in permanent brain damage. Joy had no idea about the SBAR tools. So because of his precarious and tense situation, Joy failed to inform the actual cause to the doctors. If he had communicated properly, he could have avoided the mental agony that he and his wife suffered. His wife would have got the correct treatment and would have been better placed. Even the doctor, who felt guilty for not successful in treating the wife would have been spared. Summary of Article This clearly shows how a little bit of care can prolong the life of the patient and enhance the happiness of his beloved ones. At the same time sheer neglect can endanger his life. The hospital staff should consider it their duty to contribute to the well being of the patients. There comes the importance of SBAR techniques. Conclusion It is

Developing Sustainability Indicators Monitoring For Enterprise Business Essay

Developing Sustainability Indicators Monitoring For Enterprise Business Essay The term sustainability refers to the human desire for an environment that would reap current and future benefits. Sustainability is not an absolute, independent of human conceptual frameworks. Rather it is always set in the context of decisions about what type of system is to be sustained and over what patio-temporal scale.(Allen and Hoekstra 1994) Monitoring process is an emergent and a major management response to the existing challenges in sustainability. It helps in understanding the sustainability systems and its values. Monitoring systems generally focuses on developing the various suitable tools that would help in gauging the relatedness of the sustainability practices. Basically, these monitoring systems reveal the trends and patterns of a sustainable system by constructing a good understanding of those systems. Comparison of future desired conditions with the current state of systems can be established. The changes in the entire system can be easily detected and can be used as an earlier warning against change. The growth and progress of the sustainable system in an enterprise can be effectively measured. Indicators can provide crucial guidance for decision-making in a variety of ways. They can translate physical and social science knowledge into manageable units of information that can facilitate the decision-making process. They can help to measure and calibrate progress towards sustainable development goals. They can provide an early warning, sounding the alarm in time to prevent economic, social and environmental damage. They are also important tools to communicate ideas, thoughts and values because as one authority said, we measure what we value, and value what we measure. Indicators of sustainability are different from traditional indicators of economic, social, and environmental progress. Traditional indicators such as stockholder profits, asthma rates, and water quality measure changes in one part of a community as if they were entirely independent of the other parts. Sustainability indicators reflect the reality that the three different segments are very tightly interconnected, as shown in the figure below: Segmentation of sustainable indicators As this figure illustrates, the natural resource base provides the materials for production on which jobs and stockholder profits depend. Jobs affect the poverty rate and the poverty rate is related to crime. Air quality, water quality and materials used for production have an effect on health. They may also have an effect on stockholder profits: if a process requires clean water as an input, cleaning up poor quality water prior to processing is an extra expense, which reduces profits. Likewise, health problems, whether due to general air quality problems or exposure to toxic materials, have an effect on worker productivity and contribute to the rising costs of health insurance. DESCRIPTION OF ENTERPRISE Sony Ericsson  is a joint venture established on October 1, 2001by the Japanese consumer electronics company  Sony Corporation  and the Swedish telecommunications company  Ericsson  to make mobile phones. The stated reason for this venture is to combine Sonys consumer electronics expertise with Ericssons technological leadership in the communications sector. Both companies have stopped making their own mobile phones. Sony Ericsson has strived to maintain the highest standards in our approach to sustainability. Sustainable development and production is considered to be important challenges for the future by Ericsson which demands an immediate action from responsible manufacturers. Sony Ericsson have put into effect a life-cycle approach to product development .Sony Ericsson mobile communications is a global supplier of high graphic and multimedia cell phones with various features along with accessories and pc cards. The products offer a combination of powerful technology with creative applications for mobile such as music, style, imaging, communications and entertainment. The net result is that Sony Ericsson is an enticing brand which opens up new avenues for growth in business for mobile operators and along with offering desirable, fun products to end users. In the nine years period, Sony Ericsson has been operating and it has maintained a rigorous approach to ensuring that it maintains the same standards across all chains. For Sony Ericsson, the approach to sustainability is based on the following principles: To safeguard the future profits in environmental friendly related issues. Improving the living and working conditions of all those who are involved in production of products. Not to make a negative  impact on the consumers. To improve the impact of our products and activities on the environment. Sony Ericsson have focused on low energy consumption chargers.Sony Ericsson will introduce chargers and phones with this interface well ahead of the desired industry timeline. Our portfolio of chargers is already one of the best in the industry in terms of efficiency and energy consumption. The handset was built with fully sustainable materials, the optional charger had minimal no-load power and the concept offered reduced packaging with the elimination of paper manuals. In 2008, Sony Ericsson observers were introduced. The global take back scheme and the green heart project bring us closer to our vision of being a leader in sustainability in the mobile phone industry. Constant improvising is being made by them so as to improve the working conditions and environment. Sony Ericsson set aggressive, absolute targets: Reduce the total greenhouse gas emissions from the full life cycle by 15% till 2015 (based on 2008 year levels) Reduce the total greenhouse gas emissions from So internal activities by 20% till 2015(based on 2008 year levels) Sony Ericson has continues dialogue with the parent companies on the subject of building more sustainable business. Listing Justification Of Indicators Relevant To The Enterprise ECONOMIC INDICATORS: The economic indicator refers to the system of production and consumption (including finance) and refers to the market based and to the unpaid economy. Economic prosperity is a very important element of sustainable development; it allows to combat poverty, to finance remediation of old burdens, to make changes in our development economic policy and market mechanisms must be applied in support of sustainable development, and not against it. Without denying the importance of tools such as legislation, public awareness etc., and the economy is a very powerful tool for sustainable development. Used in the right way, it provides efficient incentives to make choices for sustainable development. These incentives need to be on all levels of society, they must work in favour of sustainable development by: Making sustainable investments both in the public and private sectors profitable, Channelling research into knowledge and solutions for sustainable development Influencing consumption decision on all levels. Tele communication industry is very important for sustainable development as it generates employment wealth as well as it also provides economic benefits to the society. This all attribute raises concerns at both micro- and macro levels. The economic indicators and objective for the each specific indicator is mentioned below: Table.1 Objective Indicators Sufficient supply and goods and services GDP/ capita Efficient wealth creations Total factor productivity, cost, sales Economic systems evolution and Competitiveness Net investment, R D expenditures, Accumulated public and private debt GDP Per Capita: Gross domestic product (GDP) is nothing but the over all average of the increase or decrease of economic growth. GDP is nothing but the market value of all goods and services produced by the economy during the specific period which is often one year.2008 study by Sony Ericsson on the socio-economic impact of mobile communications in Sudan found that mobile phone access generates significant socio-economic benefits for gross domestic product (GDP), notably for people at the base of the economic pyramid. Total factor productivity, cost, sales: In simple language Productivity gives good ability to understand into inflationary pressures, and how much GDP can increase without affecting inflation. With high demand of Sony Ericsson mobiles and the company has decided to reduce operating costs, connectivity is expected to become economically viable for the local operator within three years. Net investment and capital expenditures: This indicator specifies the distribution to providers of capital broken down by interest on debt and borrowings and dividends on all classes of shares. Then Sony Ericsson describes how it has utilise its capital the level of company commitment to socially responsible investing. These are the mentioned sustainable indicators which help the Sony Ericsson, telecommunication industry to sustain in the market. ENVIRONMENTAL INDICATORS: Among the various sustainable indicators available in the monitoring system for the enterprise chosen, the prime importance moves to the environmental indicators as it drives the sustainability core concepts. These environmental indicators provide a measure of the companys impacts over the natural environment entities namely on the human, air, water and land ecosystems. The impacts of such practices can be a local or a global one depending upon the nature of the process. The ultimate target is the stake holders in common. Considering the enterprise of Sony Ericson, the threat is posed over the employees who work in the enterprise. Our enterprise corresponds to the telecom industry where by the scope of analysis for the telecom products and the facilities in Sony Ericson company is tremendous. Hence it is worth to develop indicators for the company to evaluate the effectiveness of its sustainable practices. The sustainability indicators relevant to Sony Ericsson Company are identified as below. Materials- (substances of concern) Energy- (power consumption) Products Transport Air emissions (carbon footprint) The above listed indicators are identified to be more crucial for carrying out sustainable monitoring framework for the company, Sony Ericsson. Materials (substances of concern): Considering the first indicator, materials, it refers to the various elements of concern that are used in the company. Being a strong player in the telecom industry, Sony Ericsson, produces mobile phones that incorporates brominates flame retardants (BFR) on its boards and casings. Moreover poly vinyl chloride (PVC) is also used in the chargers. Hence considering the usage of these materials in the company provides more concern over the sustainability issues in the company. Hence developing this indicator would help in the measurement of sustainability impacts of using such materials inside the company. Energy: For any industry or an enterprise, the usage of energy becomes very essential for its effective functioning. Sony Ericsson is not an exception and as it addresses the energy consumption issue through its chargers for mobile phones. This indicator provides effective measurement of the energy consumption that would help the company to incorporate processes that would lead to lesser energy consumption for the sustainable future. Products: Sony Ericsson continues its operations in the telecom industry through its various ranges of mobile phones and accessories that pose a question whether they are bio-degradable or not. The toxicity levels in the products and their environmental impacts can be measured using this indicator. Hence for a product based company like Sony Ericsson, this indicator becomes very significant for ensuring sustainable practices. Transport: Transport is an inevitable indicator in any sector as the movement of either goods or services becomes a mandatory process in the work areas. Considering Sony Ericsson, the usage of transport service, the kind of modes used, the frequency and intensity of transport processes involved in the company is really high which can affect the environment in many bad ways. Thus this indicator is more relevant to the company in identifying the impact that companys transport operations are projecting towards the environment. Air emissions With a large company like Sony Ericsson, the production capacities for their plants in various locations are tend to be generally larger. This results in the production of more carbon dioxide emissions across the nearby areas of the plant locations. So, careful monitoring of such emissions and controlling it becomes very important for the company to evaluate the amount of air emissions of the company. SOCIAL SUSTAINABILITY INDICATORS Apart from having economical and environmental sustainability it is as much as important for the company to be socially important too. Since every company they are socially bounded, it is important for them to be connected with the society. For a company to be effective and sustainable, both the individual and community resources need to be developed and used within the context of four guiding principles equity, social inclusion and interaction, security, and adaptability. Telecoms industry is playing as a very important player in shaping up the economy. The five main indicators of Sony Ericsson for social sustainability are as follows: Stakeholder involvement Human rights and business ethics Equal opportunities and non- discrimination Health and safety Bribery and corruption Sony Ericsson maintains good monitoring systems on this sustainability to have better output. Stake holder involvement Stakeholders are those who have a direct relationship to, or are affected by, our business. They include investors, customers, employees, suppliers, industry partners, governments, end-users, non-governmental organizations and the media. So it is important for any organisation to have a good relationship with them. By having sustainable relationships with the stakeholder provide the company with long run benefits. Stakeholder involvement towards a particular company creates a good image for the company among the public. Human rights and business ethics Business engagement in human rights is not only a responsibility but also an opportunity. It is very crucial for any company to behave in a socially and ethically exemplary way and operates business in compliance with all national laws and regulations. This is a main indicator for company to find out whether it is sustainable or not. Equal opportunities and discrimination One of the main indicators that should be addressed in sustainable development requires companies to provide equal opportunities to all regardless of their gender, race and disabilities. Most of the research identifies that gender disparity as one of the important issues that need to be addressed by the industry, including attracting more women into professional jobs. By having equal opportunities make the company to have better sustainable practices. Health and safety: Health and safety is one the most important indicator that production industry should concern about. Providing employees with health and safety standards must be addressed properly. The action plan included installing protective railings, improving processes and equipment for chemicals handling, and implementing health and safety procedures for corrective and preventive action. Bribery and corruption: Another main issue that should be addressed the companies is bribery and corruption. Sometimes as like human rights problems, is a large scale problem that cannot be addressed the companies. So companies must make careful consideration in regard to this problem which has a direct impact on sustainability of any company. CRITICAL ANALYSIS AND EVALUATION OF LISTED INDICATORS Justification For The Economic Indicators: China, India, Indonesia and Brazil are among Sony Ericssons 10 largest markets in sales share. Emerging markets represent around one third of global GDP, and network sales in emerging markets grew an estimated 15 percent in 2008, representing over half of network sales. High growth market: The above mentioned statistical data proves that the Sony Ericssons GDP is increasing to sustain in the market. Moreover, connectivity is an instrument to generate economic opportunity. In fact, a 2007 Deloitte analysis of sub-Saharan Africa, Latin America, the middle east and Asia pacific confirms that a 10 percent increase in mobile penetration leads to a 1.2 percent increase in gross domestic product (GDP) in developing countries twice the equivalent impact in developed markets. Applying life- cycle thinking to telecom network helps reduce the total cost of ownership for customers by demonstrating how to optimize energy. Two studies conducted by Sony Ericsson in 2008 showed in the lowest segments, money transfer, learning and mobile applications in health are in high demand. This shows that the company is done the research and addressed the capital investments, profit and share holders value to sustain in the market. Table.2 categories of economic indicators: Provides information on /measures Economic issues addressed Stake holders directly affected Main customers, market share contribution to GDP Contribution to GDP and wealth creation Customers, national governments Financial viability of business and wealth creation Capital investments, profits, share holders value, wealth creation, revenue distribution Shareholders, creditors, insurers Types of product, sales, earnings, values added Sales, earnings and value added Employees, customers, creditors, shareholders. Thus the above mentioned Economic Indicators as provided information on measures and also addressed the economic issues and how the stakeholders are directly affected. The additional indicators include generally- applicable measures of economic performance such as earnings before interest and tax. The micro economic issues have traditionally dominated business decision making with a focus on short term returns, which is in the telecommunication industry often based on production volumes rather than on valued added products and services. ENVIRONMENTAL INDICATORS: Indicator material The material indicator provides information about the various substances and elements that are used in the products and processes of the company namely Sony Ericsson. The various chemical substances like PVC, BFR and lead in the manufacturing of mobile phones and its accessories are taken into account in this indicator. One of the main substances highlighted by the media is brominates flame retardants (BFR) that reduces the risk of fires in the mobile phones. The major risk of BFR is that it becomes a dioxin under uncontrolled incineration. The company also strives to removes this substance from its charger and cable cases. Thereby the company has phased out the BFR in most of its products. Moreover Sony Ericsson takes the pride of becoming the first mobile phone firm to eradicate the entire use of BFR in its products. The other major substance is the poly vinyl chloride (PVC) because it releases hydrochloric acid and dioxins that gets accumulated in the animal fat and causes cancer to human due to the various carcinogens. Sony Ericsson worked hard to find alternatives for PVC and finally from 2007 all new Sony Ericsson products were PVC free. Other substances of concern were the phthalates, beryllium and antimony were also found hazardous and hence as an attempt to go environment friendly, the Sony Ericsson products are now almost free from such elements which can be very well evident from the companys report over sustainability. Table.3 sustainable indicator framework for social sustainability Indicator Provides information on/ measures Environmental issue(s) addressed Stakeholders directly affected/interested Materials Use of substances of concern like PVC, BFR, beryllium etc. Use and depletion of resources Suppliers, contractors, NGOs, national governments Energy Energy use and efficiency, use of renewable resources of energy.

Indicator -energy The indicator provides measures on the usage of the energy and its efficiency and the usage of renewable sources of energy. With respect to the company, Sony Ericsson the mobile phones and their chargers come into picture regarding the energy or power consumption. Considering the total energy life cycle impact of a mobile phone, there is a no load power consumption issue. Sony Ericsson tried to reduce this and achieved a 0.15 w of average no load power in its mobile phone chargers. Indicator product The product indicator provides information about the environmental impacts that happens throughout the life cycle of the product. It exhibits the other hazardous and toxic properties of the mobile phone products and its accessories of Sony Ericsson. The product gathers more importance in identifying the measure of the sustainability in a company like Sony Ericsson as the entire business rolls out of its products. The company has come up with the initiative towards the development of the mobile phone product that is environmentally sustainable. In 2008, the company initiated a concept called green heart. According to this concept, the entire life cycles of products are revised and the usages of various elements are identified to be environmental friendly. Indicator transport and logistics: The indicator provides information about the distances involved in the transportation of products and the employees as well in the company. This indicator throws light on the usage of the various non-renewable resources and the corresponding emissions that would pose a considerable threat to the environment. Sony Ericsson collaborates with the logistics companies so as to reduce the impact of transport on the overall carbon footprint. The company framed out a separate environmental friendly guideline in selecting the vehicles and fuels for its transport operations. According to the life cycle assessment made by the company in 2008, it was found that 3.7 kg of carbon dioxide emission resulted out of the transportation of which 90% contributed from the outbound transportation. Thus the serious efforts have to be made to join with Logistics Company and reduce the weight of packaging as well so that overall impact of transportation can be minimized. Indicator air emissions (carbon footprint) The indicator provides information about the amount of pollutants that the company introduces to the land, air and water ecosystems. It also defines the level and severity of the impact and the corresponding impacts on the environment. Sony Ericsson has been planning out for larger volumes of production because of business constraints and this causes a larger emission of carbon dioxide into the air. The three major activities were identified to contribute towards carbon emission namely factories, offices and travel. Table.4 Table.5 The impact of business travel is another problem accounting for higher carbon emission. Reducing the long distance travel by introducing alternative meeting arrangements like Tele-Presence systems, an advanced video conferencing technique have been initiated as an effective alternative to reduce business travels. These all techniques were thought for reducing the companys total carbon emission from its business operations. SOCIAL SUSTAINABILITY INDICATORS: Companies are paying more attention to the social dimension of sustainable development, mainly due to an experienced shift in stakeholder pressures from environmental to social-related concerns. During the last decades of the 20th century, various significant steps were taken to draw the social dimension of sustainable development into open. Sony Ericsson has taken the following social issues for their sustainability in the market. Stakeholder involvement Human rights and business ethics Equal opportunities and non- discrimination Health and safety Bribery and corruption Table.6 sustainable indicator framework for social sustainability Indicator Provides information on/ measures Social issue(s) addressed Stakeholders directly affected/interested Stakeholder involvement The level of commitment to external stakeholder Stakeholder involvement All external stakeholder Human rights and business ethics The level of commitment to protecting human rights of all stakeholders, employees Human rights and business ethics. All stakeholders, employees, trade unions. Equal opportunities and non-discrimination The level of commitment to non-discrimination and to provide equal opportunities Equal opportunities and non-discrimination Employees, trade unions, national governments Health and safety Employee health and safety Health and safety Employees, trade unions, national governments Bribery and corruption The approach to avoiding bribery and corruption Bribery and corruption Local communities and authorities, national governments, NGOs, creditors Indicator stakeholder involvement Board participation is crucial for the implementation of underlying values for sustainable development and preservation of cultural values. Therefore, involvement of local communities and other stakeholders is crucial in decision making process. Sony Ericsson seeks to respond promptly to stakeholder concerns. They conduct an annual stakeholder survey identifying the top-ranked social, environmental and economic issues for customers and investors. They measure employees views in annual surveys and polls. In 2008, both investors and customers were particularly interested in supply chain management. Indicator -human rights and business ethics Protection of human rights is another relevant sustainability of the social concern that should be addressed when considering electronics industry. Sony Ericsson respects all human rights, including the right to freedom of expression of ideas and as tools for democracy. At times the telecom industry can encounter conflicts in realisation of these rights. Sony Ericsson is addressing the relevant issues to us and our market, but at present, considers that the main concerns in this area fall within the operators domain. As society understands of these issues evolves and the border between operator and vendor changes, Ericsson will reassess its position. Indicator -equal opportunities and non- discrimination Addressing sustainable development requires companies to provide equal opportunities to all regardless of their gender, race or disabilities. Sony Ericsson is making headway in a male dominated industry, and the number of women in the workforce increased worldwide from 12,000 in 2004 to more than 17,000 today. The number of women occupying the top 200 roles increased from 12 percent in 2007 to 13 percent in 2008, while those in line management positions remained steady at 18 percent. Our objective is to develop a management team in which the number of females is proportionate to the female workforce as a whole Sony Ericsson leadership development initiative for employees nurtures key capabilities and competencies and helps set clear goals. We seek to strengthen and deepen leadership qualities at all levels of the organization. During 2008, we launched 122 training sessions to support the initiative and 1,979 managers participated, compared to 78 sessions and 1,281 participants in 2007. To maximize learning opportunities, we mix classroom sessions with informal learning such as mentoring, job rotation, coaching, and interactive feedback. This provides employees with practical support in developing the skills to spearhead and service technological convergence. Indicator health and safety In addition to wages and benefits that are universally important, one of the employee-related issues related to occupational health and safety. Occupational health and safety (OHS) is a global priority for Ericsson. In 2009 we will align our existing locally tailored OHS approach with a globally coordinated system applicable to all markets. Unit heads will ensure that they set appropriate OHS standards that are realistic, attainable and consistent with local operating conditions and legislation. During the year we will finalize a group policy on OHS that will be rolled out throughout the business. . Indicator -bribery and corruption Corruption is one of the main obstacles in equal distribution of wealth. The Ericsson group management system, implemented and monitored wherever we do business, ensures integrity and high standards of conduct. A whistle blower procedure is in place for employees to report violations relating to accounting, internal controls and procedures or fraudulent practices. In 2008, all market unit employees took the anti-corruption e-learning. We also offer training courses educate employees on the code of business ethics and anti-corruption. CONCLUSION Sustainable development has become very significant especially in the telecom industry. In order to respond to the various sustainability challenges forced in the industry, sustainable development becomes very crucial. The framework for the monitoring system developed with the corresponding indicators; provide a comprehensive tool for measuring sustainability in the telecom industry. The proposed indicators in the above discussion, addresses to the key environmental, social and economic issues that are prevalent in the tel

The three stories I have chosen to study are: Flight by Doris Lessing,

The three stories I have chosen to study are: Flight by Doris Lessing, Superman and Paula Browns New Snowsuit by Sylvia Plath and Chemistry by Graham Swift. In these three stories the writers explores complex family relationships. Choose three stories, where the writers present difficult relationships between family members, compare and contrast these relationships. The three stories I have chosen to study are: ‘Flight’ by Doris Lessing, ‘Superman and Paula Browns New Snowsuit’ by Sylvia Plath and ‘Chemistry’ by Graham Swift. In these three stories the writers explores complex family relationships, through a variety of techniques: imagery, mood and atmosphere, symbolism and structuring the stories to built up to a climax, when there is a point of realisation for both character and reader. All three stories begin by presenting idyllic family relationships but as the stories progress things change. The story Flight by Doris Lessing is about an unnamed old man who keeps pigeons, he worries about his granddaughter, Alice. He has seen his other granddaughters leave home, and he is possessive of Alice and jealous of Steven, her boyfriend. The old man argues with Alice about her behaviour, and complains to his daughter, Alice's mother Lucy. At the start of the story the old man shuts up his favourite pigeon, rather than let it fly. When Steven, the boyfriend, makes him a present of a new pigeon, he is more able to accept what is going to happen, and he lets his favourite go. The ending of the story is has more than one possible meaning: Alice has tears on her face, as she stares at her grandfather. But I do not know if they are for him, for Steven, for herself, or for some other cause. And we do not kn... ...d that she is to blame for the damage to the snowsuit. In this story, Plath explores the themes of: corruption and betrayal, material possessions and human values, man and superman, fantasy and reality. One way the writer uses to explore these themes is the use of symbolism; in the story flying is a symbol of possibility and imagination. At the start, the narrator dreams of flying, and seems able to believe in her dreams. At the end, flight is no longer a possibility and the airplanes vanish with Superman's cape. The story contrasts two costumes – one is Superman's famous blue suit, with the red cape trailing behind; the other is Paula's powder-blue snowsuit. They seem to represent opposing ideas. Superman's costume is a symbol of justice and miraculous deliverance from evil. Paula's snowsuit comes to represent self-indulgence and petty materialism.
