Albert Camus’ Political Writing and Career

Camus’s Political Writing/Career Through his political writing, Camus expresses a variety of philosophical ideologies that are in many ways similar to those expressed in â€Å"The Stranger. † In the writing, Camus explores various ideas that are reflective of how society appears to him. * 1943 Joined a French resistance called the â€Å"Combat† who opposed the Nazis. Had an underground newspaper; Camus became the editor, under the name â€Å"Beauchard,† criticized French collaboration with the Nazis †Now the only moral value is courage, which is useful here for judging the puppets and chatterboxes who pretend to speak in the name of the people†¦ – written in the newspaper The content usually tried to convince people to act with strict moral principals This is where he developed his idea that though human life may seem pointless since everyone must meet death at one point in time, it is still sacred; and each person must be responsible for their own actions and consequences. the content of newspaper likely expressed his ultimate distaste towards the actions of the Nazis and the violence erupting due to their ambition for power. Innocent people falling under their control and abuse. his goes with Camus’s ideology that men should be responsible for what they make of themselves in the universe. However, he strongly opposes the Nazis likely because they are not held responsible for the genocide; they instead, are encouraged and feared, not held accountable for the millions of deaths they’ve caused. Meursault knows that death is the ultimate consequence to murdering the Arab; he has no personal, or emotional ties with the dead man; he accepts this truth; his insensitivity actually provides a means for him to accept the idea of existentialism. This gives the impression that Meursault sees the murder as a consequence and the cause of his current problems. Also, only during his trial and imprisonment, Meursault recognizes that he is responsible for his own life, and realizes his mortality. Through writing, it can be seen that Camus’s personal political beliefs are rather left wing, though not communism. He is a socialist. Explores the morals of humankind, and his support for anti- totalitarian government. The idea of exercising control over the freedom and will of others. This is somewhat reflective of the society that Camus chooses to portray in â€Å"The Stranger. Most people conform to society, and thus society as one has specific beliefs and ideologies that are accepted by the general population and deemed as â€Å"normal behaviour. † However, Meursault is an exception; thus, he is called â€Å"The Stranger† to the society, an outlaw. He does not care about what other people think of him, or his act ions. His actions are ultimately rejected, and thought of as heartless to the rest of society. * Shortly after World War II, he publishes â€Å"Neither Victim nor Executioner† in Combat which expresses key moral questions, in a variety of essays. Relates to the idea of genocide and murder, this piece of writing mainly expresses: 1. People are living in a â€Å"murderous world† and that they must â€Å"reflect on murder† and know and accept the consequences that come with it. It can be seen that Camus is a moralist, and strongly believes in justice. Similar to his ideology in â€Å"The Stranger† in the way that Meursault, who murdered the Arab, was actually held guilty and responsible for his actions. When Meursault was put before the judge and the public official tells him to turn to Christianity, he disagrees even though his life depended on it. This displays that Meursault values emotional honesty over protecting his own life. He accepts his punishment, and the consequences that come with murder. 2. People should â€Å"carefully weigh the price that they must pay† and Camus is debating the idea of whether through world war, conflicts will actually be resolved once and for all; that if even after â€Å"several generations of sacrifice,† they will not come closer to a world society. In â€Å"The Stranger,† Meursault shows utter indifference to the man he had murdered. He did not consider the possible consequences before he shot the man, and simply instinctively kills the Arab without much consideration for what he himself would end up as. Camus explores the idea of existentialism; the role that man plays, and that he is responsible for his own actions, in the midst of a meaningless and empty world. From the ideologies expressed in â€Å"Neither Victim nor Executioner,† it seems as though Camus purposely made Meursault blind towards weighing the price he would have to pay upon murdering the Arab, and thus places focus on the process of his realization. The war can be thought of as a parallel to the physical fight that Meursault and the Arab engaged in; the ultimate conflict was not solved through murder and physical action. Society still remained the way it was, and instead of Meursault changing the views of society, he was instead forced to submit to it. * Camus wrote for â€Å"L’Express,† from 1955-1956. This was a French magazine that opposed the war in Algeria, and also the use of torture. Similar to this, â€Å"Reflections on the Guillotine† was an essay written by Camus, expressing his opinions against capital punishment, and was awarded the Nobel Prize in Literature. The absurdity of the society is reflected in its creation of a standardized justice system which uses capital punishment through the guillotine to give meaning to Meursault’s murder and actions. In order to highlight the true meaning behind the murder, society uses capital punishment to bring the matter out. The absurd overcomes rational thinking, and Meursault views death with happiness at the end, simply because he has found a genuine sense of acceptance towards the â€Å"gentle indifference of the world. †

Failure Is the First Step to Success

â€Å"Failure is the first step towards success† is one of the most heard quotes and is again and again told to us in every step of life, but how often do we realize its importance or live by its mantra? Honestly, we don’t! We just expect the fruit to come to us without working over its plant. Getting up requires falling. If a nine month old gave up trying to walk after his first fall, he would never be able to walk again, simply because he gave up. We can relate this to anything we do or anything we try to. To succeed in something, we need to keep this in our mind that we are going to fall. A very famous quote regarding this explains very clearly that â€Å"ITS NOT THE FALLING PART THAT’S HARD, IT’S THE GETTING UP† . The only way we can learn to rise is when we have been through certain circumstances. When we know what we did wrong in the first place, when we have tried every known method that’s exactly when it will dawn on us – the right way to get up. Success depends on you. If you have fallen time after time, its time to build a different strategy for getting up, you will succeed! Many people have a serious misconception when it comes to â€Å"failure† because they put negative labels on people they deem to have failed. It's important to understand that any time we fail at something, whether it's large or small; we are one step closer to success. Nothing ends in failure, if you don't let it, and your attitude is what will lead you into turning failure into success. As an easy mind up, a man fall but then get up then again, fall and then again get up, and every time the man try again, he learns and earns more experience and gains guides on how to handle his getting up the next time. You shouldn’t be dishearten or anything with the fall you get the first time, but instead learn from it on how to handle the situation again in a much easier way! Forget about the consequences of failure. Failure is only a temporary change in direction to set you straight for your next success. So just go ahead and don’t let these meaningful falls get on your nerves! Go ahead and get up!

Monopolies good or bad Essay

A monopoly is a single company that owns all or nearly all of the markets for a type of product or service. A monopoly is at the opposite end of the market structure. It is where there is no competition for goods or services and a company can freely charge a price or prevent market competition. Monopolies have three built in assumptions, one seller, no substitutes or competition, and extremely high barriers to entry. Examples of monopolies are public utilities and US Postal Service. So what are the social characteristics of monopolies? They act as the single supplier. The organization can gain complete control over the market by becoming the sole provider of a good or service. The lack of competition leaves a company with greater control over the quality of production. It also gives the company the ability to pump up prices without the fear of being challenge by other companies. This forces the customer to either buy from the monopoly or go without. A monopoly has access to specialized information. By doing this, the company maintains complete control over the market. This information may give the company the benefit of special production practices. The specialized information may also come in the form of legal tips regarding trademarks, copyrights and patents. Taking control over this special information gives the company an edge while leaving all of its competitors at a disadvantage. A monopoly has a unique product. The organization gains control over the market by offering a product or service that is unlike any other. The product or service does not have a substitution. The company may use specialized information such as legal patents, copyrights and trademarks in order to establish legal authority over the production of certain goods and services. So over all are monopolies good for the economy? Since monopolies are the only provider, they can set pretty much any price they choose. They can do this, regardless of the demand, because they know the consumer has no choice. Not only can monopolies raise prices, they can also supply inferior products. Monopolies are also bad for an economy because the manufacturer has no incentive to innovate, and provide new and improved products. Another reason monopolies are bad is that they can create inflation. Since they can set any price they want, they will raise costs to consumers. To answer the questions are monopolies bad for the economy the answer is yes. They are not good for the consumer or economy that is why they are so limited here in the US.

Exam question Essay Example | Topics and Well Written Essays - 1000 words

Exam question - Essay Example The case of Taco Co of Australia v Taco Bell P/l (1982) ATPR 40-303 sets forth the guidelines of what is deceptive and misleading. There must be a relevant section of the public that the statement is aimed; in this case as good as new are the purchasers of ovens; as is the information of serving in the last month. That there was a misled consumer/bystander who came to an erroneous conclusion, which is the belief that the oven was just serviced. Finally, the reason for the misconception needs to be discerned, which in this case is directly from the mouth of the representative. Therefore in the case of Commercial Ovens co there is a breach of s. 52, but there has also been a breach of s. 53, which is a specific false representation which is also a criminal offence. There are a variety of remedies for Beta Restaurant which are under s. 79 fines if there is a breach of a criminally sanctioning section, such as s. 53. Prosecutions have to be done by the ACCC. In addition there are injunctions, as s. 80, which can be made by any person. The applicant need not have suffered from the misrepresentation, as per World Series Cricket P/L v Parish (1977) ATPR 40-040. There can also be the disclosure of information or corrective advertising, which is also contained within s. 80, as per Janssen Pharmaceutical P/L v Pfizer P/L (1986) ATPR 50-654. There are also damages as covered under s. 82 that Beta may also receive. The applicant needs to establish three scenarios, which are; a loss or damage has occurred; the conduct contravenes; and the loss or damage was caused by the respondent's conduct. In this case there has been a loss due to the loss of business, because the deserts were not ready. The conduct has contravened Part V because there has been a misr epresentation. Finally, if Beta had known about the servicing and actual state of the oven then they would have bought or planned differently. The misrepresentation therefore has caused the loss. The damages would be the amount if the misleading conduct had not happened, in addition as per Steiner v Magic Carpet Tours P/L (1984) allows for mental anguish or loss of enjoyment damages also to be added to the actual damages. Beta is probably entitled to both sets of damages because the misleading information will have led to loss of reputation, which would cause mental anguish. The one fact that Beta has to remember is to sue within 6 years from when the damage is suffered. 3. Will the ACCC be interested in Commercial Ovens Co. (2 marks) The answer is yes because Commercial Ovens will have breached s. 53 for direct misrepresentation over the servicing of the ovens, which lends itself directly to the statement of as good as new. Therefore criminal sanctions should be taken by the ACCC. Question 2: Matt and Bill's partnership to be a legitimate partnership in business has to satisfy three categories, which are; carrying on a business; in common; with a view to a profit.

Introduction To Political Science Essay Example | Topics and Well Written Essays - 2250 words

Introduction To Political Science - Essay Example The essential test of a democracy has been the belief that the source of political authority must be and remain in the people and not in the ruler. The people have the freedom to determine the nature and content of political power, to place and replace magistrates in positions of political trust, to enact and revoke the laws by which they are governed. In short, it will be self-government; it will be in consonance with and be based upon the development of personality and individuality in every self. (Barker, 1958, p.36). It will be government by the people, not as an unorganized mass but as an organized society of living selves; not in terms of gender, color, ethnicity or other differentiating stipulations in society, but as citizens of the country. It will not rest on mere numbers, but on the quality and value of social life, particularly on the two pillars of Liberty and Equality, which are at once its foundation and its product. To the extent that there is a denial or abridgement of either of these principles to any section of people in a society, to that extent there will be the 'shortfall' in the operation of democracy in that society. And the section of the people deprived of the enjoyment of any of these principles will find it difficult to be elected to positions of political trust. Based on these tenets, we examine why so few women in the USA, as of now, occupy positions of political leadership in the country. Denial of civic equality to women. For much too long a period, American democracy has not been an inclusive political community. Large sections of 'citizens' were excluded from enjoying the basic rights of a citizen, namely the right to vote. For more than 150 years after the American democratic and republican constitution came into existence, American women were denied the right to vote. They secured it only after years of 'struggle' to be recognized as equal citizens of the country along with the men citizens, with the passage of the 19th amendment to the U.S. Constitution in 1920. This was granted about a century after Frances Wright, a Scottish immigrant had first advocated women's suffrage in a series of lectures in 1826. The 'struggle' to secure equal rights for women in electing the representatives to the national and state legislatures continued sporadically during the first half of the 19th century. In 1840, Lucretia Mott and Margaret Fuller, the author of the book The Great Lawsuit; Man vs. Woman became acti ve in Boston. Efforts to gain various women's rights were subsequently led by women famous in the American feminist movement such as Susan B. Anthony, Elizabeth Cady Stanton, and Paulina Kellogg Wright Davis. In 1869 Susan B. Anthony and Elizabeth Cady Stanton founded the National Woman Suffrage Association with the object of securing an amendment to the Constitution in favor of woman suffrage. The American Woman Suffrage Association, headed by Lucy Stone, was also formed at this time by those who believed that suffrage should be brought about by amendments to the various States constitutions. In 1890, these two bodies united into one national organization, led by Susan B. Anthony, and known as the National American Woman Su

Sustainable design Essay Example | Topics and Well Written Essays - 750 words

Sustainable design - Essay Example Sustainability involves all spheres of life and none of the spheres could be ignored as these spheres are interrelated. Sustainability involves development of an ecologically aware, socially just and economically responsible society (Web: "What is Sustainability & Why Is It so Important"). Sustainability as defined by World Commission on Environment and Development (1987) is, "forms of progress that meet the needs of the present without compromising the ability of future generations to meet their needs" (Web: "Definition For Sustainability"). Sustainability is imperative in order to assure that a constant supply of water, material and resources will be available to prevent health and well being of the living beings and on the other hand to protect the environment from hazards (Web: "Sustainability"). E.g. A continuous water wastage may lead to water scarcity for future generations. However, it is destined to desalinate saltwater, with sustainable use of water one can postpone the fat ed time. 2. How is sustainability a new way of thinking? How is it related to ecology and systems thinking? Sustainability enables one to think in a novel way. It enables one to understand the balance between society and natural resources as natural resources play vital role for the existence of life on the planet. However, the natural capital stock and services of ecological systems contribute for the welfare of human beings (directly or indirectly) and represent the economy of earth. Estimations reveal that economic value for the whole biosphere approximates to US$ 16-54 trillion per annum. It is essential to understand the estimates to make the services of ecosystems apparent, to highlight the magnitude of global ecosystem services, to understand the areas seeking urgent attention, motivate research and debate. It could be concluded that problems and uncertainties are attributed to the representation of minimum values. Ecosystem involves habitat and biological systems. Living bei ngs derive food (goods) from the ecosystem while services in the form of waste assimilation, together they are referred as ecosystem services. E.g. natural resources provide job prospects to many while living forms fulfill some part of the nature's requirement (Costanza et al., 1997). 3. How can designers integrate principles of sustainability into their designs and promote the sustainability movement? Why are the social and cultural aspects of sustainability so important? A growing concern is observed regarding appreciation of nature among the policy makers and decision maker in private companies to transform an unsustainable system to a sustainable system by involving the fundamental that economic growth is not solely a social event but it is also an environmental episode. Thereby, igniting a feeling to focus on green economy to make certain a sustainable as well as desirable future. Therefore social and cultural aspects of sustainability is imperative in order to promote social e quality, eradication of poverty and to secure future of the coming generations in terms of natural resources. Such focus is further harmonized by means of biodiversity as well as ecosystem services, since resilient ecosystem is essential for long-term socio-economic development (Web: "Nature And Its Role In The Transition To A Green Economy"). Principles of Sustainable Design and Pollution Prevention (Kim, 1998) Economy of Resources- Strategies include conservation of energy, water and

Education Assignment Example | Topics and Well Written Essays - 1500 words

Education - Assignment Example Given this in perspective, one must understand that the schools need to form a very strong channel of communication with the parents and the community in order to provide quality service to the community. This will paper will give insight into how the channel of communication can be made stronger and deeper through various methods via which the schools can communicate within the community. The schools under discussion would be elementary schools so the entire discussion would revolve around these schools only. I want to address this problem because communication between schools and communities is of vital importance; the stronger the communication, the more effective the interaction between the teachers, the parents and the students. This interaction will help teachers in discussing the performance of children with their family members and will help the school over problems such as students’ absence. Education is an entire cycle which is dependent on the action and communication of students the community, the residents and the educators. Effective teaching is directly related to effective communication. Unless communication is not effective, the desired results won’t be seen within the community at large. Various studies have been conducted in this regard. According to Jeri La Bahn (1995), parents would feel delineated from their children’s schools because they would feel un welcomed at schools. A lot of times, parents would feel that education is not important. The study opined a lot of ways through which parents can be involved in schools in a constructive way. There was another study conducted by University of Illinois. According to this research, children tend to perform better when their parents are more actively involved in school. This means, that it is better when parents talk to teachers more often and are better aware of their children’s

What Should Eastern European Migrants to UK Do In Order To Be More Gainfully Employed - Dissertation Example What Should Eastern European Migrants to UK Do In Order To Be More Gainfully Employed? According to European Commission website (European Commission, 2011 http://ec.europa.eu/enlargement/5th_enlargement/index_en.htm), in May 2004 Poland, the Slovak Republic, the Czech Republic, Latvia, Slovenia, Lithuania, Hungary and Estonia joined European Union. The United Kingdom was only one of three European countries to allow the free migration of workers. The ability to work and to live in abroad made thousands of people leave their home and go to look for a better living in UK. Hull like other UK cities experienced rising number of immigrants coming from East and Central Europe. According to Department for Work & Pensions, the total number of immigrants coming to Hull between 2004-2008 from east and central European countries was 6.780. Most of the people coming to Hull are from Poland, Lithuania, Latvia. Migrant workers come with a broad range of qualifications and skills. They intend to choose low skilled jobs through recruitment agencies and take a low- income employment. This research will look into the reasons why migrant workers have a tendency to take vacancies in low skilled jobs market despite the level of skills they have. The immediate aims of this research are: †¢ To explore skills and qualifications of East European workers; †¢ To clarify primary obstacles faced by immigrants wanting to access better employment; †¢ To look into reasons why East European workers don’t adapt in English labor market. ... In order to achieve these aims, in the course of researching, a survey would have to be done to know the hopes and needs of Eastern European (EE) migrant workers in the UK. The laws and regulations affecting those Eastern European Migrant workers have to be scrutinized and summarized to see how they can affect their hopes and needs. The survey questionnaire should gather some information about their strengths and weaknesses as Eastern European Migrant workers. A review of their opportunities, rights, and privileges will then shed light on the usefulness of those strengths in the UK. Finally, in order that this formal research can contribute some insights to the existing body of knowledge about Eastern European Migrants in the UK, and to the improvements in productivity with the UK, an attempt to recommend plans will be done for the conversion of Eastern European Migrant workers at Hull into becoming more productive for the UK.

It gives equal treatment in trying to access employment regardless of race, religion or belief, gender, civil status. By December 2010, the government (GEO 2010) â€Å"announced that it will bring into force section 159 of the Equality Act 2010 in April 2011. This will help employers achieve a more diverse workforce by giving them the option, when faced with candidates of equal merit, to choose a candidate from an under-represented group.† In 2005, Hull had a sluggish economy in 2005. Growth was low. Productivity was low. Earnings were low. So the Local Authorities of Hull developed a strategy and called it NDC or New Deal for Communities Sanderson, I., Green, A., and

Advantages and Disadvantages of Partnership Assignment - 1

Advantages and Disadvantages of Partnership - Assignment Example The author of the paper states that perhaps the greatest advantage of a partnership has to do with the fact that a level of shared responsibility can be created that allows for more efficient distribution of work tasks and project management. As the old adage goes, two heads are better than one. Additionally, further capital is available to run the entity due to the fact that both partners are personally invested in the success and business ventures that the firm will engage in. In tandem with this increase in potential capital, there is also a relative increase in the overall capacity for borrowing. For instance, an individual decides to engage in a business venture alone will only be able to leverage borrowing potential commensurate with their own debt limitations. However, when two or more individuals are engaged in a partnership, each of these individuals can leverage capital via borrowing mechanisms that allow for a higher level of funding to be raised. Another potential benefit that the partnership provides is with regard to the ability of income splitting. Ultimately, income splitting is merely a mechanism through which the potential profits of the firm can be provided to various stakeholders within the partnership as income/profit the ventures that have proven beneficial. The benefit of all of this has to do with decreasing the overall tax burden is not representing a situation in which a single individual is responsible for representing all profitability and income as incumbent and contingent upon their own tax burden.  Of all of the business advantages that a partnership includes, the advantage of limited external regulation is perhaps the single advantage that individuals interested in such a type of business organization reference most often in terms of a key decision factor that prompted them towards partnership. Ultimately, income splitting is merely a mechanism through which the potential profits of the firm can be provided to various stakehold ers within the partnership as income/profit the ventures that have proven beneficial. The benefit of all of this has to do with decreasing the overall tax burden is not representing a situation in which a single individual is responsible for representing all profitability and income as incumbent and contingent upon their own tax burden.

Unit 6 Essay Example | Topics and Well Written Essays - 500 words - 1

Unit 6 - Essay Example Lastly, David (2011) indicates that the domestic and the international events have not ceased to augment. The organizations are being affected by these changes to a great extent; thus, making it difficult to achieve strategic evaluation. These aspects have made the set strategies impossible to implement. Even with the constant search for information, strategic evaluation has not proven to be the best measure to curb the challenges that face the organizations today. David (2011) also says that these challenges have made strategic evaluation not assess its performance effectively, as well as take the right measures that would see the survival of the organizations. An analysis of the objectives of the strategic evaluators would be a perfect move to limit these challenges. For successful contingency planning, Rao, Rao & Sivaramakrishna (2009) recommend seven steps. The first step involves identifying the favorable and unfit factors that could lead to the set strategy failing (Rao, Rao & Sivaramakrishna, 2009). Secondly, the authors indicate that is advisable to denote the factors that would elicit effects on the set strategy (Rao, Rao & Sivaramakrishna, 2009). This is to mean when the contingent events are expected to take place. Thirdly, an assessment of the implications of every contingent event is good for contingency planning (Rao, Rao & Sivaramakrishna, 2009). This step would place the planners at a good position to estimate the expected benefits and losses that could occur from the selected events. The fourth step entails designing contingent plans, then evaluating the counter effects of the selected contingency plan so as to identify which plans are the best and which ones should be overlooked (Rao, Rao & Sivaramakrishna, 2009). The sixth step involves determining the warning signals in an opportune time so as to counter them appropriately. Lastly, Rao, Rao & Sivaramakrishna (2009) indicate that developing plans to

The big 5 personality traits Essay Example for Free

The big 5 personality traits Essay Introduction: 1. The aim of this study was to examine the relationship between the ‘Big Five’ personality traits (neuroticism, extraversion, conscientiousness, agreeableness and openness) and career success (Seibert Kraimer,2001). A questionnaire was sent by post to 2781 graduates of business and engineering. 496 alumni took part in the survey (318 males and 178 females). The conclusions were that agreeableness is not well related to career success; there is no relationship between the other four factors and career success. High people orientated jobs showed a poor relationship between agreeableness and salary. Low people orientated jobs shows no relationship between agreeableness and salary. METHOD: 2. Career success can be defined as the positive psychological and work related outcomes as a final result of work completed by each individual. Construct definition is the overall basic idea which is being examined; career success. Operational definition describes what the variables are and how each is measured. The variables are extrinsic and intrinsic career success. Greenhaus et al. measured intrinsic career success with a five-item career satisfaction scale. Each participant was asked to show their levels of satisfaction with their careers, 1 being the lowest and 5 being the highest. Two self-reports were used to measure extrinsic career success. Each participant was asked to show the number of promotions they had gotten throughout their career. They also had to show their annual salary level. Altogether the variables included log salary, promotions, career satisfaction, work experience, MBA degree, metropolitan area, number of employees, gender and occupation type. (Seibert Kraimer, 2001) RESULTS: 3. Central Tendency-The way in which quantitative data clusters around a midpoint. Dispersion- How far your scores are from your measure of central tendency. Mean is a measure of central tendency  Standard Deviation(S.D) is a measure of dispersion.  Sex: a categorical form of data (male/female). This is badly represented as the standard deviation is above the mean (if S.D is higher than the mean, a minus is applicable). For gender you can’t measure central tendency but you  can measure dispersion. Personally, I think that gender doesn’t belong in the table. Promotions: Are badly represented as the S.D is very high. I think that using the mode instead of S.D would resolve this issue. Career satisfaction: is represented good. Both the mean and S.D appear to work well. Career satisfaction was measured using Greenhaus et el.(1990) scale of career satisfaction. I don’t think any changes need to be made. Agreeableness: is represented good. However I think the definition for agreeableness leaves a lot to be desired for. In saying that, both the mean and the S.D appear to work well. My suggestion would be to leave it but maybe reconsider the definition. (Seibert Kraimer, 2001) DISCUSSION: 4. (A)In my opinion, I don’t agree with the definition of agreeableness in this context. ’Agreeableness is ones interpersonal orientation, ranging from soft-hearted, good-natured, trusting and gullible at one extreme to cynical, rude, suspicious, and manipulative at the other’ I don’t agree with this as only alumni from business and engineering were surveyed. Other people orientated jobs such as teachers, nurses etc. were not included. Therefore it cannot be generalised. In my opinion, I think that people high on agreeableness (in this case) have lower extrinsic career success. Whereas they may be happy in their jobs they may not get promotions. (B)Yes, I do think that agreeableness causes lower salaries for individuals working in high people orientated jobs. People who are more agreeable are more likely to fill out surveys. They are more likely to do more work for less money; therefore promotions would not come into account as employers may take advantage of these workers. (C)The sample attrition is the dropout rate which occurred. The surveys were mailed to 2781 homes of business and engineer graduates. Each individual had graduated 3-39 years prior to the survey.773 were returned (28% response rate). 668 had fully completed the survey. Out of that 668, 49 were unemployed, 33 worked part time and 96 were self-employed. The final number of participants was 496. If the sample attrition was included this could have influenced the data as the sample size would be larger and more random. Self-employed people may have different levels of personality traits, e.g. higher extraversion as they  have leadership skills. Unemployed people may be high in agreeableness as they may lack confidence. I think that would have a great effect on the overall data. (D)Two variables could be combined within one individual e.g. agreeableness and extraversion. The individual may not get a promotion due to the level of agreeableness they obtain; however with the high levels of assertiveness and sociability in an extraversion they could also get promoted. Other variables included: log salary, promotions, career satisfaction, work experience, MBA degree, metropolitan area, number of employees, gender, occupational type and the big five personality traits. By only surveying business and engineer graduates it made the study easier for themselves as there are less levels in these jobs than in other occupations such nurses or doctors. The Big 5 personality traits definitions: Neuroticism: indicates adjustment versus emotional stability. Individuals who score high on neuroticism are characterized by high levels of anxiety, hostility, depression, and self-consciousness. Extraversion: High levels of extraversion indicate sociability, warmth, assertiveness, and activity, whereas individuals low on extraversion may be described as reserved, sober, aloof, task-oriented, and introverted. Openness: is defined in terms of curiosity and the tendency for seeking and appreciating new experiences and novel ideas. Individuals who score low on openness are characterized as conventional, unartistic, and narrow in interests. Agreeableness: Agreeableness is one’s interpersonal orientation, ranging from soft-hearted, good-natured, trusting, and gullible at one extreme to cynical, rude, suspicious, and manipulative at the other. Conscientiousness: indicates the individual’s degree of organization, persistence, and motivation in goal-directed behaviour. Achievement-orientation and dependability or conformity have been found to be primary facets of conscientiousness (Seibert Kraimer,2001) High people orientated occupation is where the individual is a sociable, people person, with good interpersonal skills. People with a high people orientated occupation must be able to do the following: speak, persuade, serve, supervise, instruct, mentor and negotiate with others. Some jobs include sales, division managers, executive managers and human resource  managers, where interaction with other people is frequent. Low people orientated occupations include the opposite of high people orientated occupations. People with low people orientated jobs would work as a financial or market analyst, a MIS specialist, or an IT department where little involvement with people occurs. (Seibert Kraimer, 2001) CONCLUSION: 5. I think that there is enough evidence to support that the big 5 personality traits are related to career success. The results were as follows: The full set of personality variables was not related significantly to promotions but extraversion was correlated significantly with promotions. Intrinsic and extrinsic outcomes have been considered as related but to distinct aspects of career success. Extrinsic career success was associated with extraversion and, with less consistency, openness to experience and agreeableness. Individuals who were higher on extraversion received greater salaries and more promotions than did those lower on extraversion. Individuals who were less open to experience and less agreeable received greater salaries compared to their more open or agreeable peers. Intrinsic career success was associated with extraversion, neuroticism, and agreeableness. Individuals who were more extroverted, less neurotic or less agreeable experienced higher levels of career satisfaction than their less extroverted, more neurotic, or more agreeable peers. Moderated regression analysis involving extraversion and agreeableness was unable to find any major effects against intrinsic career success, suggesting that these effects are consistent across occupations requiring different levels of interpersonal interaction. Extraversion was related most consistently to career success, exhibiting positive relationships with salary, promotions, and career satisfaction. Extraversion plays in managerial advancement of persons in people-oriented and non-people oriented occupations. Negative relationship of neuroticism to career satisfaction implies that individuals high on neuroticism evaluate their careers more negatively. Negative relationship of agreeableness with extrinsic career success was provided. Although agreeableness was not related to promotions, it was related negatively to salary for individuals in people-oriented occupations. Agreeableness appears to be a liability in jobs that require  more people skills, and perhaps more â€Å"political† skills. Agreeableness also was related negatively to career satisfaction. There was no support for the hypotheses that neuroticism and conscientiousness are related to the two measures of extrinsic career success, salary, and promotions. Findings suggested that individuals who were more open received lower salaries. Since these results were not hypothesized, confirmation of these relationships in future research is required. The results of the control variables examined in this study generally are consistent with previous career research. Strengths: The results found were accurate. The results found were similar to previous studies. They were able to prove some of their hypostasis. Gives opportunities for future research. Weaknesses: Fault with gender and promotions: mean and standard deviation. I personally don’t agree with some of the definitions. Only business and engineering graduates were surveyed. The sample was small. Self-report, people may not be 100% honest. Most alumni were from Caucasian background. (Seibert Kraimer, 2001) BIBLOGRAPHY Scott E. Seibert and Maria L.

Can The Legalisation Of Drugs Be Justified Philosophy Essay

Can The Legalisation Of Drugs Be Justified Philosophy Essay When we want to decide if a particular substance should be legalized, by which I mean the substance is not entirely prohibited and is available to non-professional recreational users, the first enquiry should be into whether or not people will come to harm as a result of the drug being made available. But this assumption rests upon an initial normative ethical decision where we ask on what grounds a government or legal entity should be entitled to prohibit certain substances by use of force and coercion. John Stuart Mill puts forward two possible conditions which must be met for a government to interfere with someones privacy and freedom of behaviour. The first principle is what I will describe as the harm principle, while the second one is what I will call Mills soft paternalism, which is a practical extension of the harm principle. Mill argues that the only criteria for limiting freedom of behavior with legal or physical measures are if the consequences of the actions result in harm to another member of society. If a persons activities do not result in harm to another person then a government has no rational grounds for preventing that behavior, even if the behavior breaks a social taboo. As Mill puts it: the only purpose for which power can be rightfully exercised over any member of a civilized community à ¢Ã¢â€š ¬Ã‚ ¦ is to prevent harm to others  [1]  . According to the harm principle, then, we would have grounds to legalize drugs as long as we could see no way in which this would result in harm to another person. This means that harm is a jointly sufficient and necessary condition for prohibiting a substance or a type of behavior. If these conditions are not met then we have no rational grounds for making drugs illegal. The practical implementation of this principle means we would be justified in prohi biting a school bus driver from smoking cannabis while driving, as this could result in harm to other people, but we would not be justified in stopping him from smoking cannabis in his own home. The second condition, which follows naturally from the harm principle, is a condition of soft paternalism. If we are entitled to prohibit types of behavior in order to reduce harm then it follows that harm can befall someone due to ignorance and lack of consent. The soft paternalist stance means that we would be entitled to prohibit someone from taking a drug if they did not know the possible harmful consequences of taking the drug or if they were not of a sufficient metal state to appreciate any danger. If we were to legalize drugs then we would also have to satisfy the sub conditions of consent and fore knowledge, which are jointly sufficient conditions for freedom of behavior along with the harm principle. The practical results of this policy would mean that a government would have no grounds in preventing someone from harming themselves by using drugs which are highly addictive and potentially self destructive drugs such as heroin as long as they consented (i.e. acted on their ow n free will) to using the drug and had fore knowledge of the consequences. We would only make selling heroin illegal to children or people who were not entirely responsible for their own behavior such as mentally disabled people or insane people. We would also be obliged to make the consequences of taking such a drug clear to the consumer. The first possible objection to the conclusion of Mills argument outlined above is that there are far reaching social consequences to legalizing drugs which the harm principle does not cover. We could consider, for example, the extortionate cost of drug treatment which it could fall on the state to provide. We might also be suspicious that legalizing drugs and making them available on such a wide scale would result in a moral decline and a threat to an orderly civilized community. These objections essentially expose Mills harm principle and soft paternalism as being socially myopic. Although drug related behavior which may result in harm befalling people other than the drug taker are a priori undesirable, and that harm is therefore a sufficient condition for prohibiting drug use, it is not the only sufficient condition. It does not follow that, just because individual recreational drug use does not result in immediate harm to another individual, it will not cause havoc if it became a widespread cultural practice. Mills argument for justifying the legalization of drugs, his harm principle, cannot be the sole criteria for making ethical judgments. This means that the harm condition may be a sufficient condition for deciding if drugs should be legalized, but it does not mean that it is the sole sufficient condition nor does it mean that it is a necessary condition. The point to be made here is, I think, that normative deliberations over ethical first principles are inconclusive due to this type of enquiry not being able to really see what the consequences of drug legalization are. We should supplement the harm principle and soft paternalism with descriptive ethical questions, such as what the cost of the war against drugs? W.F Buckley Jr. points out the wider social implications of drug taking in a social environment where it is prohibited by law. The fact that drugs are illegal makes them extremely expensive which mean that many drugs users must turn to theft to satisfy their habit, which may require stealing up to $5,000 worth of jewels [or] cars  [2]  . If the fact that drugs are illegal results in a likelihood of harm to other people then it follows that we should at least consider the legalization of some drugs on these grounds. The harm principle, then, must be considered in a wide scope which include sociological and economic conside rations such as those pointed out by Buckley. Another possible objection to the legalization of drugs due to Mills conditions being met is that some drugs are highly addictive, so addictive that it constitutes a breech of an individuals freedom of will. An individual cannot continue to consent to use drugs if he is addicted in an extreme physiological sense to a drug such as heroin. Strong drug addiction does not satisfy the consent condition of Mills harm principle which means that we should prohibit someone from obtaining such a drug even though he consents to this addiction initially. Soft paternalism would extent to prohibiting the sale of highly addictive drugs in order to protect the individuals legal and moral autonomy. The harm principle here is too narrow to encompass the unique effects drug taking can have. We must instead rely upon a Kantian understanding of the moral agent, in which we understand a moral agent is an end in itself, and since powerful addiction would violate this, then we should prohibit highly addicti ve drugs. Kants categorical imperative claims that human freedom is realised in the adoption of humanity as an end in itself.  [3]  This means that even though someone consents and has foreknowledge of drug addiction and decides to get himself addicted to drugs his decision is essentially immoral. A possible condition for the legalization of a drug could be that it is not so addictive that it will interfere with an individuals autonomy or encourage him to act in ways which are harmful to him. If we assent to these arguments there would be no grounds to justify the legalization of heroin while there would be grounds to legalize and permit the use of drugs like cannabis and salvia divinorum which are not highly addictive in a physiological sense. The problem with this objection can be outlined by clarifying what exactly free will is, i.e. what conditions have to be met for an individual to have free will. Frankfurt defines the freedom of will as being the possibility of having done otherwise  [4]  , which means that as long as ones will is synchronized with ones actions, one has free will. If you desired not to take a drug and someone physically forced you to do this you would not have free will as you could not have done otherwise. Frankfurts position on free will is what I will describe as a coherentist position, by which I mean an individual acts freely if his primary intentions coincide with their behaviour even if they are unable to prevent this behaviour. If an individual who is addicted to drugs and is unable to act in any other way because of this then this is still an instance of free will as long as this behaviour coheres with previous decisions made under consent and foreknowledge. A heroin addict is not forced to take drugs even when addicted in the sense that they could have done otherwise. Although his behaviour is determined by the drugs his will is not impeded in the way that brainwashing or direct physical coercion by another person will impede free will. Kane describes the condition of personal autonomy as the power to be the ultimate producers of [ones] own end and the power to make choices which can only and finally be explained in terms of [ones] own [will] (i.e., character, motives, and efforts of will) .  [5]   If these conditions are met then there is no realistic breech of the consent and foreknowledge and there is no ground to prevent the sale of highly addictive drugs. We can conclude, in regard to the above arguments, that Mills harm principle and the sub-conditions of assent and foreknowledge give grounds for legalizing the sale of drugs as long as these conditions are met. The only grounds on which we could make a drug like heroin illegal is by taking a what I will describe as a strong paternalist approach to welfare, in which citizens are prohibited from partaking in activities which will inflict harm of them even though they themselves desire or are aware of harmful consequences. This must be balanced, however, upon the implications of actually making these activities illegal. A strong paternalist approach to car safety is to make it illegal for motorists not to wear seatbelts. There are only positive consequences of this legislation. Making heroin illegal, on the other hand, increases the price of heroin to levels only affordable by serious crime, increases the risk of negative health implications do to unregulated heroin production and inclu des the risk of people infecting themselves by using unregulated drug taking equipment and diverts money and resources into enforcing these laws at the expense of others. Lord Devlin, on the other hand, argues against the legalization of drugs considered taboo or immoral in a society from a view point which does not necessarily rely on the negative consequences to individuals or the harm to an individuals autonomy. Lord Delvin argues, first of all, that any social group posses a right to protect its own existence. He then goes on to argue that particular morals and ethical standards which a community stands by should be enforced to protect the existence of a community. He then concludes that moral standards can be maintained by force and the curtailing of individual liberty. Society, he claims, may use the law to preserve morality in the same way it uses it to safeguard anything else if it is essential to its existence.  [6]  If it could be shown that the legalization of drugs such as cannabis or heroin would contradict moral standards then these deviations from [the] societys shared morality are capable in their nature of threatening the existenc e of society and therefore cannot be put beyond the law.  [7]   The problem with Lord Delvins argument is that it fails to give an adequate explanation as to why a deviation from a routine moral standard is necessarily a threat to a societys existence. It simply does not follow that if an individual practises certain types of behaviour in the privacy of his own home, such as smoking cannabis, this results in a negative impact to the survival of a society. It also does not take into account that particular customs of a society may have evolved to meet specific needs which is no longer relevant. On the other hand, moral standards may have been enforced due to a lack of scientific understanding. It is certainly true that widespread incest could result in a threat to the existence of society due to genetic diseases becoming more prevalent in society, and it is therefore rational and just to enforce compliance to non-incestuous marriage. But it difficult to see how the legalization o f a non addictive hallucinogenic drug with few side effects during moderate consumption could pose any threat to a societys existence. To conclude, I will summarize the conditions which should be met for the legalization of a substance to be considered ethically legitimate. It must first of all only be made available to those who consent and have foreknowledge of the consequences of the drug, no matter how addictive or harmful it may be when it is consumed. The results of the consumption of the drug should also have no negative consequences towards society at large. This could mean that a drug which, when consumed, could result in harmful environmental impact or damage to others who are not consuming the drug, should be banned. This could also mean that people are prohibited from taking the drug at particular public locations. It could also mean that the drug is only allowed be consumed at special facilities in which it can be regulated. The practical implementation of this could mean that one would be permitted to smoke cannabis consume ecstasy at particular venues.

Prototype Modeling of Smart Grid Technology at Ciit Lahore

Prototype Modeling of Smart Grid Technology at Ciit Lahore CHAPTER 1 INTRODUCTION TO SMART GRID 1.1 Introduction 1.1.1 Definition: The smart grid system is vast collection of technologies to provide an electricity network having the ability to solve the major issues related to reliability, cost effectiveness of electric power and decentralization or grid dependency The smart grid technology using renewable energy sources transferred electricity towards user side with the concept of integration of renewable energy sources. 1.1.2 Why Smart Grid Technology Adopted The demand of electricity is increased so much by the passage of time, which creates some major problems related to conventional electricity network. By 2020 energy demand will be doubled from the present demand [1]. Smart grid is the result of such efforts which are performed to make availability of electricity more reliable, economical and user friendly with the concept of decentralized network due to two way communication of electricity through network[2]. The Architectural model of a 21st century power system that interconnects everyone to affordable, abundant, clean, reliable, and efficient electricity anytime, anywhere. The purpose of Smart Grid is also to integrate several renewable resources with our national Grid and enhances the efficiency; reliability and thus providing a hassle free Transmission of electric power. It also contributes to reduce carbon emissions and providing a pollution free environment. 1.2 Back Ground 1.2.1 The European Development in the Area of Smart Grid In the next three decades European member state will expend about 750 billion in power infrastructure. This amount will expend on generation and networks. The European Technology plate form was developed in 2005 to solve the problems of Network Owners, operators and users[3]. 1.2.2 Smart Grid Development in USA In USA the Smart grid developments initiated during first Bush Administration[4]. In 2002 a DOE study describes the hundred of million of Dollar spent In US power systems on transmission practices and results a proposal of construction of transformed national electricity grid upto2030 providing the best and secure transmission of electricity[5]. 1.2.3 Smart Grid Development in Australia Under the Energy Transformed Flagship the Intelligent Grid Program was launched on 19 Aug, 2008. This Program researched in the fields of Control methodologies and economic modeling for distributed generation, Social impact of Intelligent grid, New housing developments and micro grids[6]. 1.3 Design Description 1.3.1 Features of Smart Grid The most important features of Smart Grid Technology are: Integration of Renewable Sources Battery Storage option Provide electric power to both AC and DC loads Advance Monitoring 1.3.2 Proposed Methodology Above figure shows prototype modeling of smart grid system at micro level along with the integration of several renewable energy resources such as small wind plant and solar panels. The charge controllers are special devices used for the purpose to control the abrupt change in voltage and stop the reverse flow of current towards PV or wind turbine systems, and also control the charging and discharging of batteries. An integrator is also one of the most important components of our project. The function of this device to integrate powers from both energy sources in a way that during operating time of the sources loads will directly get power from these sources and at night or the time when these sources are not operating loads are facilitated through battery banks. 1.4 Advantages of Smart Grid A. Motivates and Includes the Consumer Smart Grid is a end user device it motivates the consumer to generate a free source of electricity and to utilize it in household appliances when electricity from Grid is not available. B. Provides Power Quality for 21st Century Needs It provides power free of disturbance, sags, interruptions and spikes. C. Markets Opportunities Smart grid supports energy markets that encourage both investment and innovation. D. Operates Efficiently and Optimizes Assets Smart grid is easy to install infrastructure, transmit more power through existing systems and optimizes easily with present grid. E. Reduction in cost of power infrastructure When renewable energy sources are infused into the power grid, end-use demands can be adjusted to available power supplies. The ability to manage and reduce peak demands demolishes the need for costly peaking and â€Å"just-in-case† power infrastructure. F. Reduced use of polluting plants Some existing powerplants are not environment friendly which is adversely affecting the environment around us. Smart grid can produce pollution free generation of electricity. G. Clean power market During serious air pollution alerts, power plants and heavy industries sometimes shut down.

CHAPTER 2 LITERATURE SURVEY Contents: World Wide Survey of Renewable Energy Demand Supply Gap in Pakistan Depletion in Oil and Gas Energy Sources in Pakistan Wind Energy Solar Energy 2.1 World Wide Survey of Renewable Energy Renewable energy has an essential contribution in world energy generation. So many projects are under consideration regarding to renewable energy. 2.1.1 Global Status Report This report describes the market condition, investment and targets as well as policies. The report doesnt describe analysis or conclusions, though it reveals some extra ordinary facts regarding the renewable energy . By the end of 2005 only 45 countries were included in the achievement of renewable energy targets which are increased up to 76 in 2009. According to this report last year was the best era for renewable energy. Capacity in developing countries grew to 119GW, or 43% of the total. Including Pakistan and magnolia less or more than 8-0 countries has started plantation of wind power plants at commercial measures[7]. Some achievements of the year 2008 are: In just 1 year the capacity of solar photovoltaic plants tripled to 3 GW from 200 KW. Wind power by 29% and solar hot water increased by 15%. Grid connected photovoltaic systems increased up to 13GW, wind energy grew up to 250%, 121GW and total power generation capacity from renewable energy boost up to 75%. Spain becomes the super power in the field of grid connected PV systems with inclusion of 2.6GW. Germany also takes some handy steps and added 1,5GW in their system. Some other developed countries also provide large contributions like USA(3ooMW), Italy ( 300MW) , South Korea ( 270MW) and Japan (240MW) respectively . in total 16GW is the generation of solar including off-grid by 2009 worldwide. Table2.1 Energy Added and Exists in 2009-2010 2.2 Demand Supply gap in Pakistan If we give a look at demand supply graph then we will come to know that the difference between demand and supply is becoming wider and wider by the passage of time .the scenario in 3rd world countries is totally discriminated e.g. Pakistan. Needs are increasing exponentially but we are desperately lacking in finding out a good solution. if we have an eye view we may find 3 reasons of demand supply gap. Increase in prices of oil and gas , increase in population and increase in cost of energy . 2.2.1 Energy Demand With the increase in population energy requirements are also increasing. All the industry and the production of our daily need in dependent upon electricity . 2.2.2 Energy Supply Current eras total production of energy does not meet the current requirement of energy , though the end results are critical in the sense of increase in demand supply gap . Serious steps are needed to be 2.2.3 Energy cost If we have eye view on last few decades we will come to see the highlighted reduction in the reserves of oil and natural gas, which causes the increase in the cost of per unit production of electricity. This is also the reason of widening the demand supply gap. 2.2.4 Sustainability level The systems which are to be used for the generation of electricity must be stable, but unfortunately we have not surety of sustainability level of present system and the graph is gradually decreasing according to our present and future demands . This decrease in sustainability may overcome by using alternative techniques. 2.3 Depletion in oil and gas A large amount of electricity is being produced by fossil fuels and the present value of electricity generated by fossil fuels is increasing. According to the European energy commission and International energy the present reservoirs of oil and gas are not sufficient enough to meet the future requirements. so as the result after 10-12 years we have the depletion in the percentage of Oil using for the generation of electricity as shown in fig 2.2. As from the above it is obvious that from 1930 to one word till 2010 there is continuous growth in both oil and gas reserves but after 2010 there is deep declined. If the above graph follows the same pattern there is near future we will be totally dependent upon alternates of energy generation. 2.4 ENERGY SOURCES IN PAKISTAN The primary energy supplies today are not enough to meet even the present demand. More, a very large part of rural area does not have the electricity facilities because they are too expensive to be connected to the national grid. So, Pakistan like other developing countries in the region is facing a severe challenge in energy deficit. The development of renewable energy sources can play an important role in meeting such challenge. If we see around yourself Pakistan best suits for Solar (PV, thermal), water, wind and Wastes. These are the best renewable sources and Pakistan doesnt lack these. Pakistan can b benefited from these as substitute energy in areas where these renewable sources exist. Renewable energy Fossil fuels Nuclear power 2.4.1 Renewable energy It is energy which is produced by natural sources such as wind rain solar and geothermal heat. 2.4.1.1 Types of renewable Energy Wind Biomass Solar Wave and tidal Geothermal These all sources are best placed in Pakistan and we are not lacking in any at all , thus we can produce great amount of energy using these renewable sources , Capturing renewable energy by animals , plants and humans does not permanently deplete the resource. Fossil fuels are renewable but on a very long time-scale, are exploited at rates that may deplete these resources in the near future. 2.4.2 Fossil Fuels It includes natural gas, oil and coal . fossil fuels are lacking in Pakistan as well the world therefore renewable sources are needed to meet th essential needs 2.5 Wind Energy Wind energy is one of the best of renewable sources and probably suits Pakistan atmosphere at peak. As our project is related to wind energy as well. In Pakistan wind energy projects are working under the Pakistan Meteorological Dept with the financial collaboration of Ministry of Science and Technology which are accomplishing many such projects in Pakistan. About 3% of the total Pakistans land area is termed as good to excellent for utility scale production of electricity. Fig2.3. shows the variations of wind speeds in different areas of Pakistan Average wind speed in Lahore is 3m/s as shown in Fig.2.4 . Therefore for the prototype smart Grid system, average wind speed must exceeds the theoretical values as given in[10]. 2.6 Solar energy Its one of the types of renewable energies, as in our project we are working on solar energy, in photovoltaic system solar cells covert sun radiation to DC electricity. The provinces of Sindh , Punjab and Baluchistan and the Thar desert are specially suited for the utilization of solar energy. The solar statistics in Pakistan is highly favourable for energy generation. According to Fig2.5. the South western province offers perfect condition for utilization of solar energy. Since Pakistan locates near the equator so it has relatively high UV index as compared to other regions of the World. The solar characteristics graph in the Lahore region is shown in Fig. 2.6. Lahore city also offers suitable condition for harnessing solar energy The average sunlight hours lies between 7 to 8 hours per day which is approximately 2700 hours per annually. Graph in Fig. 3 shows the UV index of Lahore during a day time in the month of April. Usually the radiation intensity has its maximum value at noon .And value of solar radiation reaches its maximum value during the mid of summers. Chapter No 3 PHOTOVOLTAIC SYSTEM Contents: Introduction to solar panels History of PV system Photovoltaic Cell Architecture Implementation of PV system Battery 3.1 Introduction: Solar cell or photovoltaic cell is the device use to convert sunlight into electricity. It works on the basic principle of photovoltaic effect. 3.1.1 Photovoltaic effect When the photons of light falls on the semiconductor material. The photons try to knockout the electrons from the conduction bands. As the energy gap between valence and conduction band increases and when a sufficient amount of energy is projected by the light photons .the electrons knocked out from their respective atom and started to move freely. These free electrons moves towards n-side and holes created due to the deficiency of electrons in this region moves towards p-side to recombine themselves .This difference of potential allows the flow of current. The PV cell absorbs incoming light photons in p-type. This p-type layer should be synchronized in such a way that it can absorb as many as photons possible and set free as many as electrons possible, to make a radiant flow of current. In order to make and efficient flow solar cell , the surface of the cell should be kept rough to maximize the absorption of photons while reflection should be minimized in this way maximum conduction can be achieved 3.2 History The photovoltaic cell was developed in 1954 at Bell Laboratories. The first highly efficient solar cell was developed by Daryl Chapin, Calvin Souther Fuller and Gerald Pearson in year 1954 using a diffused silicon p-n junction. Firstly, cells were developed for toys and other minor uses, as the cost of their production was very high. Design of solar cells is improved day by day to utilize it for more applications. The applications for that solar panels are used are different and there are three levels of generation 3.2.1 First Generation: First generation cells are single junction devices and they have large area also having high quality with reduction in production cost 3.2.2 Second Generation: These materials are developed to address energy requirements and production cost. They reduce high temperature processing as vapour deposition, electroplating and Ultrasonic nozzles. 3.2.3 Third Generation: The aimof these technologies is to improve poor electrical performance of second generation technologies with low production cost. 3.3 Photovoltaic cell architecture A PV module consists of a silicon cell .These cell are connected in series or parallel manner in order to produce desired voltage and current .Inside a PV cell a circuit is present that is sealed from the envoi metal protective lamination .A PV panel consists of one or more modules joined together. Finally these panels are combined to make a single PV array which is a complete electricity producing unit. The performance of a PV array or its modules is rated by its maximum throughput power under S.T.C (Standard Test Condition).STC is defined as when a PV modulecell is operated under 25  °C (77F), with an incident solar irradiation of 1000 W/m2 with the spectral distribution of 1.5 air mass. These are the perfect condition for a PV module to operate in , but in actual the performance of a PV module is almost 80 to 90 percent of its STC rating. The operating lifetime of a PV module is between 20 to 30 years .Most of the manufactures offers warranty of 20 or more years of its DC output power to a sustainable amount .PV modules are also lice censed under (UL) qualification test for its reliability checks. 3.3.1 Types of Solar Cell Now a days there are various types of cell materials are developed. Multi junction PV cells are made in order to increase the cell efficiency while decreasing its volume and weight. But they are far more expensive then an ordinary silicon cells. The maximum efficiency of a PV cell is achieved almost to 30 percent by doping different intrinsic material together .Example of the exotic materials are Gallium arsenide and Indium serenade etc. However silicon cells are the most common and widely used PV cells. There are three major types of Silicon cell: Amorphous silicon solar Cell or Thin Film Cell Mono-crystalline Wafers Poly crystalline Cell Amorphous Silicon Solar Cell Amorphous technology is often seen in small devices, such as those in garden lamps or calculators, although amorphous panels are also increasingly used in other larger applications. They are formed by depositing a thin film of silicon onto a sheet of different material such as steel. The panel formed as one piece and each cell is not as visible as in other types. Efficiency of an amorphous solar cell is between 6 and 8%. The Lifetime of an amorphous cell is however shorter than that of crystalline cell. Amorphous cells have current density of about 15 mA/cm2,and the voltage of the cell without any connected load is 0.8 V, which is more as compared to crystalline cells. The efficiency of amorphous solar panels is low as those made from individual solar cells, although improvement has been made over recent years to a point where they can be use as a practical alternative to panels made with crystalline cells. Crystalline silicon solar cell The maximum efficiency of silicon solar cell is around 23 %, by adding some other semi-conductor materials it can increase up to 30 %, it depends on wavelength and semiconductor material being used. Crystalline solar cells are made up of wafers like stuff, which has about 0.3 mm thick and diameter of 10 to 15 cm. They can generate approximately 35 mA of current per cm2 of area at voltage of about 550 mV at full illumination. Crystalline solar cells can be wired in series or parallel to produce a solar panel. As each cell produces a voltage of between 0.5 and 0.6 Volts, 36 cells equipped in series are needed to produce an open-circuit voltage of about 20 Volts. This is enough to charge a 12 Volt battery under certain conditions. Although the efficiency of mono-crystalline cells is slightly higher as compared to that of a polycrystalline cells, but there are some practical difference in their performance. Crystalline cells have longer lifetime than that of amorphous solar cells. In our project we have used crystalline silicon cell because they are more efficient yet lesser in volume as compared to other types of solar cell, easily available in market and it is more economical. Polycrystalline Cell Polycrystalline silicon, also called poly silicon , consists of small silicon crystals of Polycrystalline cells which can be recognized by a visible grain, a â€Å"metal flake effect†. Semiconductor grade (solar grade) polycrystalline silicon then form to single crystal silicon, that is randomly associated crystallites of silicon in polycrystalline silicon are converted to a large single crystal[11]. Single crystal silicon is used in manufacture most of Si-based microelectronic devices. Polycrystalline silicon can be available up to 99.9999% pure. 3.4 Implementation of PV system: 3.4.1 Types of PV system There are three types of PV system being implemented around the world depending upon its function and integration with other energy resources. Standalone PV system Grid Connected PV system Hybrid Systems Stand alone PV system This type of system is usually present in our wrist watches, calculators and in space crafts also. These are dependent totally on its self generated power through solar panels and are directly used by DC loads or AC loads through inverter. In some system battery bank is also available to store the unused power to facilitate loads during night or under low light conditions. Further more a charge controller is also required in order to avoid battery from over charging and deep discharging. An inverter is also employed to provide power to AC loads. Grid Connected PV system In grid connected type the PV module has also backed up with WAPDA line or Grid connection. In this way if load is not getting enough power from the PV module or its battery, it will switch to the WAPDA line. This type of system is most commonly used around the World. Its applications are found mostly in small industries and homes. Hybrid System In this type the PV system is also integrated with two or more type of energy resources which may or may not be renewable resources .For example a wind turbine, steam engine or a small hydro plant etc. Other energy sources can also be integrated depending upon climate, geographical location of the place and several other perspectives. These systems are more appropriate for remote applications such as military installation, communication stations and rural villages. 3.4.2 Design Methodology Our project is based on a Hybrid System Consisting of a PV module and a windmill as two renewable energy resources, we have chosen these sources keeping in mind the climate and terrain of Lahore. 3.4.2.1 Components of Photovoltaic system: Solar cell Panel Inverter Charge Controller Batteries Integrator The major component of our system is the integrator .The function of this device is to integrate powers from both energy sources in a way that during operating time of the sources loads will directly get power from these sources and at night or the time when these sources are not operating loads are facilitated through battery banks. A controller is placed in the integrator circuit that is continuously monitoring the voltage level being provided by the sources. If the load can operate single handed by either of the sources the rely will build its connection from load with that source while the energy generated by the second source is being stored in the batteries .If both sources are required to derive a certain load rely opens up its connection of both sources with the load. When both sources are not providing a sufficient amount of power to the loads the controller will check whether batteries could provide sufficient amount of voltage so, it will start delivering power to load from the battery bank otherwise an LED blinks indicating that system cannot provide sufficient amount of power and will shutdown eventually. 3.4.2.2 Solar Panel Characteristics Table 3.1. Solar Panel Characteristics 3.4.2.3 Experimental Values This table shows the experimental results of output voltage and output current with respect to different timings and temperature variations in a day. Table 3.2. Solar Panel Throughput 3.4.2.4 Factors Affecting Output Power STC(Standard Test Condition) The electricity produce by solar cell is in DC, the DC output of solar panel is Tested under the STC that is Cell Temperature= 25 °C Solar Radiation Intensity= 1000 W/m2.. Air Mass= 1.5 These are the standard test condition at which Solar cell gives its Maximum Efficiency, in other conditions there is almost 10 to 15 percent of decrease in the efficiency of cell with respect to its STC rating. Temperature Output power of the solar cell is inversely proportion to the increase in temperature of the cell. For a crystalline module , a typical temperature reduction factor proposed by CEC is 89 percent which means †95 watts† module will typically provide 85 Watts (95watts*0.89=85watts) under sunlight conditions during summer seasons. Mismatch and wiring Losses The performance of the system can be affected due to mismatch of module connections. The loss in power also depends upon the increase in length of wire between source and load. As the distance between source and load increases losses also increases. Therefore the distance should be kept minimal to get maximum power throughput.

By 2020 energy demand will be doubled from the present demand [1]. Smart grid is the result of such efforts which are performed to make availability of electricity more reliable, economical and user friendly with the concept of decentralized network due to two way communication of electricity through network[2]. The Architectural model of a 21st century power system that interconnects everyone to affordable, abundant, clean, reliable, and efficient electricity anytime, anywhere. The purpose of Smart Grid is also to integrate several renewable resources with our national Grid and enhances the efficiency; reliability and thus providing a hassle free Transmission of electric power. It also contributes to reduce carbon emissions and providing a pollution free environment. 1.2 Back Ground 1.2.1 The European Development in the Area of Smart Grid In the next three decades European member state will expend about 750 billion in power infrastructure. This amount will expend on generation and networks. The European Technology plate form was developed in 2005 to solve the problems of Network Owners, operators and users[3]. 1.2.2 Smart Grid Development in USA In USA the Smart grid developments initiated during first Bush Administration[4]. In 2002 a DOE study describes the hundred of million of Dollar spent In US power systems on transmission practices and results a proposal of construction of transformed national electricity grid upto2030 providing the best and secure transmission of electricity[5]. 1.2.3 Smart Grid Development in Australia Under the Energy Transformed Flagship the Intelligent Grid Program was launched on 19 Aug, 2008. This Program researched in the fields of Control methodologies and economic modeling for distributed generation, Social impact of Intelligent grid, New housing developments and micro grids[6]. 1.3 Design Description 1.3.1 Features of Smart Grid The most important features of Smart Grid Technology are: Integration of Renewable Sources Battery Storage option Provide electric power to both AC and DC loads Advance Monitoring 1.3.2 Proposed Methodology Above figure shows prototype modeling of smart grid system at micro level along with the integration of several renewable energy resources such as small wind plant and solar panels. The charge controllers are special devices used for the purpose to control the abrupt change in voltage and stop the reverse flow of current towards PV or wind turbine systems, and also control the charging and discharging of batteries. An integrator is also one of the most important components of our project. The function of this device to integrate powers from both energy sources in a way that during operating time of the sources loads will directly get power from these sources and at night or the time when these sources are not operating loads are facilitated through battery banks. 1.4 Advantages of Smart Grid A. Motivates and Includes the Consumer Smart Grid is a end user device it motivates the consumer to generate a free source of electricity and to utilize it in household appliances when electricity from Grid is not available. B. Provides Power Quality for 21st Century Needs It provides power free of disturbance, sags, interruptions and spikes. C.

CHAPTER 2 LITERATURE SURVEY Contents: World Wide Survey of Renewable Energy Demand Supply Gap in Pakistan Depletion in Oil and Gas Energy Sources in Pakistan Wind Energy Solar Energy 2.1 World Wide Survey of Renewable Energy Renewable energy has an essential contribution in world energy generation. So many projects are under consideration regarding to renewable energy. 2.1.1 Global Status Report This report describes the market condition, investment and targets as well as policies. The report doesnt describe analysis or conclusions, though it reveals some extra ordinary facts regarding the renewable energy . By the end of 2005 only 45 countries were included in the achievement of renewable energy targets which are increased up to 76 in 2009. According to this report last year was the best era for renewable energy. Capacity in developing countries grew to 119GW, or 43% of the total. Including Pakistan and magnolia less or more than 8-0 countries has started plantation of wind power plants at commercial measures[7]. Some achievements of the year 2008 are: In just 1 year the capacity of solar photovoltaic plants tripled to 3 GW from 200 KW. Wind power by 29% and solar hot water increased by 15%. Grid connected photovoltaic systems increased up to 13GW, wind energy grew up to 250%, 121GW and total power generation capacity from renewable energy boost up to 75%. Spain becomes the super power in the field of grid connected PV systems with inclusion of 2.6GW. Germany also takes some handy steps and added 1,5GW in their system. Some other developed countries also provide large contributions like USA(3ooMW), Italy ( 300MW) , South Korea ( 270MW) and Japan (240MW) respectively . in total 16GW is the generation of solar including off-grid by 2009 worldwide. Table2.1 Energy Added and Exists in 2009-2010 2.2 Demand Supply gap in Pakistan If we give a look at demand supply graph then we will come to know that the difference between demand and supply is becoming wider and wider by the passage of time .the scenario in 3rd world countries is totally discriminated e.g. Pakistan. Needs are increasing exponentially but we are desperately lacking in finding out a good solution. if we have an eye view we may find 3 reasons of demand supply gap. Increase in prices of oil and gas , increase in population and increase in cost of energy . 2.2.1 Energy Demand With the increase in population energy requirements are also increasing. All the industry and the production of our daily need in dependent upon electricity . 2.2.2 Energy Supply Current eras total production of energy does not meet the current requirement of energy , though the end results are critical in the sense of increase in demand supply gap . Serious steps are needed to be 2.2.3 Energy cost If we have eye view on last few decades we will come to see the highlighted reduction in the reserves of oil and natural gas, which causes the increase in the cost of per unit production of electricity. This is also the reason of widening the demand supply gap. 2.2.4 Sustainability level The systems which are to be used for the generation of electricity must be stable, but unfortunately we have not surety of sustainability level of present system and the graph is gradually decreasing according to our present and future demands . This decrease in sustainability may overcome by using alternative techniques. 2.3 Depletion in oil and gas A large amount of electricity is being produced by fossil fuels and the present value of electricity generated by fossil fuels is increasing. According to the European energy commission and International energy the present reservoirs of oil and gas are not sufficient enough to meet the future requirements. so as the result after 10-12 years we have the depletion in the percentage of Oil using for the generation of electricity as shown in fig 2.2. As from the above it is obvious that from 1930 to one word till 2010 there is continuous growth in both oil and gas reserves but after 2010 there is deep declined. If the above graph follows the same pattern there is near future we will be totally dependent upon alternates of energy generation. 2.4 ENERGY SOURCES IN PAKISTAN The primary energy supplies today are not enough to meet even the present demand. More, a very large part of rural area does not have the electricity facilities because they are too expensive to be connected to the national grid. So, Pakistan like other developing countries in the region is facing a severe challenge in energy deficit. The development of renewable energy sources can play an important role in meeting such challenge. If we see around yourself Pakistan best suits for Solar (PV, thermal), water, wind and Wastes. These are the best renewable sources and Pakistan doesnt lack these. Pakistan can b benefited from these as substitute energy in areas where these renewable sources exist. Renewable energy Fossil fuels Nuclear power 2.4.1 Renewable energy It is energy which is produced by natural sources such as wind rain solar and geothermal heat. 2.4.1.1 Types of renewable Energy Wind Biomass Solar Wave and tidal Geothermal These all sources are best placed in Pakistan and we are not lacking in any at all , thus we can produce great amount of energy using these renewable sources , Capturing renewable energy by animals , plants and humans does not permanently deplete the resource. Fossil fuels are renewable but on a very long time-scale, are exploited at rates that may deplete these resources in the near future. 2.4.2 Fossil Fuels It includes natural gas, oil and coal . fossil fuels are lacking in Pakistan as well the world therefore renewable sources are needed to meet th essential needs 2.5 Wind Energy Wind energy is one of the best of renewable sources and probably suits Pakistan atmosphere at peak. As our project is related to wind energy as well. In Pakistan wind energy projects are working under the Pakistan Meteorological Dept with the financial collaboration of Ministry of Science and Technology which are accomplishing many such projects in Pakistan. About 3% of the total Pakistans land area is termed as good to excellent for utility scale production of electricity. Fig2.3. shows the variations of wind speeds in different areas of Pakistan Average wind speed in Lahore is 3m/s as shown in Fig.2.4 . Therefore for the prototype smart Grid system, average wind speed must exceeds the theoretical values as given in[10]. 2.6 Solar energy Its one of the types of renewable energies, as in our project we are working on solar energy, in photovoltaic system solar cells covert sun radiation to DC electricity. The provinces of Sindh , Punjab and Baluchistan and the Thar desert are specially suited for the utilization of solar energy. The solar statistics in Pakistan is highly favourable for energy generation. According to Fig2.5. the South western province offers perfect condition for utilization of solar energy. Since Pakistan locates near the equator so it has relatively high UV index as compared to other regions of the World. The solar characteristics graph in the Lahore region is shown in Fig. 2.6. Lahore city also offers suitable condition for harnessing solar energy The average sunlight hours lies between 7 to 8 hours per day which is approximately 2700 hours per annually. Graph in Fig. 3 shows the UV index of Lahore during a day time in the month of April. Usually the radiation intensity has its maximum value at noon .And value of solar radiation reaches its maximum value during the mid of summers. Chapter No 3 PHOTOVOLTAIC SYSTEM Contents: Introduction to solar panels History of PV system Photovoltaic Cell Architecture Implementation of PV system Battery 3.1 Introduction: Solar cell or photovoltaic cell is the device use to convert sunlight into electricity. It works on the basic principle of photovoltaic effect. 3.1.1 Photovoltaic effect When the photons of light falls on the semiconductor material. The photons try to knockout the electrons from the conduction bands. As the energy gap between valence and conduction band increases and when a sufficient amount of energy is projected by the light photons .the electrons knocked out from their respective atom and started to move freely. These free electrons moves towards n-side and holes created due to the deficiency of electrons in this region moves towards p-side to recombine themselves .This difference of potential allows the flow of current. The PV cell absorbs incoming light photons in p-type. This p-type layer should be synchronized in such a way that it can absorb as many as photons possible and set free as many as electrons possible, to make a radiant flow of current. In order to make and efficient flow solar cell , the surface of the cell should be kept rough to maximize the absorption of photons while reflection should be minimized in this way maximum conduction can be achieved 3.2 History The photovoltaic cell was developed in 1954 at Bell Laboratories. The first highly efficient solar cell was developed by Daryl Chapin, Calvin Souther Fuller and Gerald Pearson in year 1954 using a diffused silicon p-n junction. Firstly, cells were developed for toys and other minor uses, as the cost of their production was very high. Design of solar cells is improved day by day to utilize it for more applications. The applications for that solar panels are used are different and there are three levels of generation 3.2.1 First Generation: First generation cells are single junction devices and they have large area also having high quality with reduction in production cost 3.2.2 Second Generation: These materials are developed to address energy requirements and production cost. They reduce high temperature processing as vapour deposition, electroplating and Ultrasonic nozzles. 3.2.3 Third Generation: The aimof these technologies is to improve poor electrical performance of second generation technologies with low production cost. 3.3 Photovoltaic cell architecture A PV module consists of a silicon cell .These cell are connected in series or parallel manner in order to produce desired voltage and current .Inside a PV cell a circuit is present that is sealed from the envoi metal protective lamination .A PV panel consists of one or more modules joined together. Finally these panels are combined to make a single PV array which is a complete electricity producing unit. The performance of a PV array or its modules is rated by its maximum throughput power under S.T.C (Standard Test Condition).STC is defined as when a PV modulecell is operated under 25  °C (77F), with an incident solar irradiation of 1000 W/m2 with the spectral distribution of 1.5 air mass. These are the perfect condition for a PV module to operate in , but in actual the performance of a PV module is almost 80 to 90 percent of its STC rating. The operating lifetime of a PV module is between 20 to 30 years .Most of the manufactures offers warranty of 20 or more years of its DC output power to a sustainable amount .PV modules are also lice censed under (UL) qualification test for its reliability checks. 3.3.1 Types of Solar Cell Now a days there are various types of cell materials are developed. Multi junction PV cells are made in order to increase the cell efficiency while decreasing its volume and weight. But they are far more expensive then an ordinary silicon cells. The maximum efficiency of a PV cell is achieved almost to 30 percent by doping different intrinsic material together .Example of the exotic materials are Gallium arsenide and Indium serenade etc. However silicon cells are the most common and widely used PV cells. There are three major types of Silicon cell: Amorphous silicon solar Cell or Thin Film Cell Mono-crystalline Wafers Poly crystalline Cell Amorphous Silicon Solar Cell Amorphous technology is often seen in small devices, such as those in garden lamps or calculators, although amorphous panels are also increasingly used in other larger applications. They are formed by depositing a thin film of silicon onto a sheet of different material such as steel. The panel formed as one piece and each cell is not as visible as in other types. Efficiency of an amorphous solar cell is between 6 and 8%. The Lifetime of an amorphous cell is however shorter than that of crystalline cell. Amorphous cells have current density of about 15 mA/cm2,and the voltage of the cell without any connected load is 0.8 V, which is more as compared to crystalline cells. The efficiency of amorphous solar panels is low as those made from individual solar cells, although improvement has been made over recent years to a point where they can be use as a practical alternative to panels made with crystalline cells. Crystalline silicon solar cell The maximum efficiency of silicon solar cell is around 23 %, by adding some other semi-conductor materials it can increase up to 30 %, it depends on wavelength and semiconductor material being used. Crystalline solar cells are made up of wafers like stuff, which has about 0.3 mm thick and diameter of 10 to 15 cm. They can generate approximately 35 mA of current per cm2 of area at voltage of about 550 mV at full illumination. Crystalline solar cells can be wired in series or parallel to produce a solar panel. As each cell produces a voltage of between 0.5 and 0.6 Volts, 36 cells equipped in series are needed to produce an open-circuit voltage of about 20 Volts. This is enough to charge a 12 Volt battery under certain conditions. Although the efficiency of mono-crystalline cells is slightly higher as compared to that of a polycrystalline cells, but there are some practical difference in their performance. Crystalline cells have longer lifetime than that of amorphous solar cells. In our project we have used crystalline silicon cell because they are more efficient yet lesser in volume as compared to other types of solar cell, easily available in market and it is more economical. Polycrystalline Cell Polycrystalline silicon, also called poly silicon , consists of small silicon crystals of Polycrystalline cells which can be recognized by a visible grain, a â€Å"metal flake effect†. Semiconductor grade (solar grade) polycrystalline silicon then form to single crystal silicon, that is randomly associated crystallites of silicon in polycrystalline silicon are converted to a large single crystal[11]. Single crystal silicon is used in manufacture most of Si-based microelectronic devices.
