Freedom and Determinism Problem - Essay Example One should distinguish between the idea that events in the universe are linked causally and the idea that events in the universe are linked correlatively. In the first view, exemplified by Newtonian physics, is that the trajectories of billiard balls are determined by their interactions (using factors such as velocity, momentum, and so on). In the second view, certain events are correlatively linked to others, leading to the perception of a causal relationship. 2. Libertarianism Metaphysical libertarianism is the contrary position to determinism, holding that a human free will does exist and that free will is incompatible with determinism. A completely free will implies that no external events act upon or causally determine the chosen actions of human beings. In other words, a person is able to take any of a set of actions under particular circumstances; that is, his choice is not limited to only one possible choice, as is claimed by determinism. One should distinguish between the id ea that libertarianism applies to non-physical objects and physical objects. In the first view, the mind is a non-physical entity outside of physical causation and does not rely on the brain for causative explanations. In the second view, libertarianism implies indeterminism in the physical world (invoking ideas of newer quantum physics), which extends to the physical mind. 3. Compatibilism If libertarianism and determinism are two sides on a continuum, then compatibilism is the middle ground between those two positions. Essentially, the idea is that free will and deterministic causation are compatible ideas, making it possible to logically believe in both at the same time. Of course, compatibilists do not believe in the same kind of free will that libertarians do. While libertarians define free will in a way that is logically inconsistent with a physically deterministic universe, compatibilists define it in a manner that is consistent with a deterministic physical universe, making how one defines his terms very important in the debate. A common way of expressing the compatabilist view is explaining that man is not coerced into following his will; however, what he wills is likely subject to forces outside of his mental life. For instance, many human motivations and drives are unconscious, which points to a role both for determinism and man’s choice of actions in human life. This implies also that notions of â€Å"alternatives† used by metaphysical libertarians are not real. II. A. Do humans have free will? Humans have free will, but it is not a completely free will. Clearly, certain constraints inhibit the complete freedom of a human free will. For instance, a person cannot fly off a roof or breathe under water, even if there is a clear wish to do so. Moving physical and non-physical constraints aside, any person can clearly demonstrate a free will by choosing their actions among many alternatives. For instance, I can continue typing or get up to get something to drink. But one should notice that both of these actions are at the top of my mind because they are motivated by some process in my physical brain, subject to the causes and effects of electrical and chemical processes. This produces the compatabilist notion of free will: courses of action are suggested by my brain, which my mind eventually chooses from. Are all human actions determined? Not all human action is determined. From psychology, there are numerous examples of how human

Studying Abroad Essay Example for Free

Studying Abroad Essay Having a strong education is the best way to ensure a good future and fulfillng dreams. Therefore, I feel it is important to pursure my higher studies and have decided to study abroad, in particular. I have applied for this scholarship and chosen my major for the following reasons: to gain education of high quality, to get better employment opportunities, and to learn more about other cultures. The first reason for choosing to study IS is to gain education of high quality. As we all know, Europe is famous for the education that is provided by its strong universities, best professors, successful educational systems and methods. Graduating from prestigious colleges or universities like that is often regarded as an achievement in itself. Furthermore, a degree from a good foreign university always adds up to ones resume. Secondly, due to the lack of specialists in this major in my country, it is considered an advantage for me to have chosen to study IS because it will result in getting better employment opportunities. With the knowledge that I get from studying in such a field and applying ehat I have learned, I will have an added advantage over others. Last but not least, it is an exciting advanture to study out in a completely new enviroment. It will enable me to mature quickly and develop independence. For instance, joining the university will be the first experience to adjust to living away from family and friendes. Though there will be many difficulties like culture or lack of proficiency in laguage, Ill learn how to live on my own and look after myself after overcoming them. In conclusion, my desire to study abroad is based on getting best level education in the world, being offered better job chances, and experiencing new things. However, it does not mean that one can get this knowledge and experience just by going abroad to study. He / She must choose carefully which college to study in, and struggle for what he/she is longing for to improve oneself and ones country.

The Ethics of Stem Cell Research Essay example -- Genetic Engineering

According to the National Institutes of Health (NIH), stem cells are 1 "Cells with the ability to divide for indefinite periods in culture and to give rise to specialized cells." Stem cells are basically unspecialized cells that can, with proper physiologic or experimental conditions, become specialized cells. Specialized cells are usually called differentiated cells. These differentiated cells can then be used to repair damaged cells and eventually cure many diseases and disorders in humans. This could revolutionize the way society treats health issues. Instead of trying to destroy and sure a disease or disorder, doctors could simply grow new cells that would be able to repair or replace the damaged cells and tissue. Adult Stem Cells There are two major types of stem cells, embryonic and adult stem cells. Adult stem cells are the undifferentiated cells that are found in tissue and organs in adults. These cells are usually found mixed in with differentiated cells. These cells are used to repair and maintain the tissue in which they are found. Research of adult stem cells began in the 1960?s when scientists discovered them in bone marrow. Stem cells from bone marrow have been used in transplants for the past 30 years. Currently, scientists are unsure as to how adult stem cells develop. A major advantage to using adult stem cells is that each patient?s stem cells can be extracted, grown, and then reinserted into their body. This would ensure that the immune system would not reject the new cells. One of the problems with adult stem cells is that there are a very few number of stem cells in a sample of tissue. Another problem is that scientists are unsure about the flexibility of adult stem cells. Since they are found only i... ...ws-item94.htm >. Stem Cell Basics. 2002.

Explain the Purpose of Hermeneutics

The primary need of Hermeneutics is to determine and understand the meaning of Biblical text. The purpose of Hermeneutics is to bridge the gap between our minds and the minds of the Biblical writers through a thorough knowledge of the original languages, ancient history and the comparison of Scripture with Scripture. Through Hermeneutics, Biblical Interpretation can be achieved in three ways; historically, the message and the doctrine. The Bible is totally authoritive and inspired by God, however is it propositional or not? To be propositional means that God reveals certain truths at which we respond in accepting these truths. These certain truths may be found in scripture, creeds and or the teachings of the church. Non-propositional approach emphasise God revealing himself at which we respond with faith being a personal belief in God, resulting in us developing specific ideas and or propositions about God. A non-propositional view believes the Bible is a source book of many different accounts of human response to the divine. In Hermeneutics, there are three, among many, significant schools of thought which we are principally concerned; fundamentalism, liberal approach, and traditional interpretations of Scripture. Fundamentalism was first used in the beginning of the 20th century, whose aim was to preserve what they saw as the ‘fundamentals’ of the Christian faith from being eroded by liberal thinking. The fundamentals included the following beliefs; the divinity of Jesus; meaning he was fully God, that God’s ultimate judgement and the existence of heaven and hell and the physical resurrection of Jesus, among others. Fundamentalists believed in the doctrine of plenary verbal inspiration, this is the understanding that, the Bible is the actual word of God to the extent that it was dictated by God, word for word, to the people who wrote it down. To the fundamentals, the Bible is seen as being ‘inspired’ or ‘breathed’ by God in a direct and ‘unmediated’ fashion, meaning the actual writers of the Bible are just conduits and God is the actual author as it is God’s words that they are included, and so God is the words of the writers. Fundamentalists would declare that their view of the Bible can be found in the words of the Bible itself. Similarly Fundamentalists may argue that the Bible itself makes a clear statement of its own dependability. Since the Bible is regarded as being entirely the work of God and that God is the author it is inerrant meaning it can never be changed, questioned or challenged, to do so means you’re challenging God himself. With this idea that the Bible goes without error goes beyond the concept that it is with theological error. Rather the belief of inerrancy includes freedom from geographical, historical and scientific error as well. The second school of interpretation is Liberalism. This grew out of the discussion amongst rationalism and authoritarianism. The Liberal system of Hermeneutics suggests that the modern mentality was to govern someone’s approach to scripture, such as, if anything was not in harmony with ‘educated’ morality, it was rejected, for example Biblical concepts such as hell, sin and depravity as they offend moral sensitivities, and could not believe that their God could punish them in such a way. The Liberal method of Hermeneutics allows the Bible to be open for criticism like any other scripture, for example, miracles are not always to be accepted as they are not of certain truths and are not scientific. Another approach the Liberal system suggest is that the scripture’s text itself could be rearranged, for instance in authoritive order the law comes first however it may be argued that shouldn’t it be ordered by the times in which they were written? The reason behind this approach is that the Liberal method rejects all forms of inspiration. For a Liberal interpreter of the Biblical, the concept of revelation is redefined to mean human insight into religious truth. One of the consequences of the liberal school of interpretation is that the content of doctrinal and theological are not binding, this results to the belief that religious experience is therefore fundamental and that theology is an afterthought. The Liberals believe that the writers of the Bible accommodated their recipients and hence the Bible is not binding on us. Non propositional theology is often favoured by liberal theologians because it places the emphasis on human experience and rationality. The third school of interpretation is Traditionalism. Traditionalists maintain that the Bible is full of truth, God is revealed within the Bible and that it is inspired by the Holy Spirit. One of the key characteristics of their approach to the Bible is its emphasis on the need to understand the nature of the different types of literature within the bible. However, traditionalists would not accept the fundamentalist’s notion of inerrancy as many would acknowledge that there are mistakes in the Bible. These are seen as a reflection of both the historical context in which they are written and the human fallibility f the authors. As with Liberals, traditionalists believe that some aspects of the Bible need to be reinterpreted for today. Traditionalists place a lot of emphasis on the process of exegesis. However, after establishing the intended meaning of the author the next step in the traditional approach is the question of how it should be applied to Christian today. However, whereas fundamentalists believe that the true meaning of a text should be clear to each reader; traditionalists believe that exegesis is more of a complex process. Another characteristic of the traditionalists is that they are open to a range of different forms of scholarship, for instance, open to forms of textual and historical analysis. However unlike the liberal approach such scholarship is generally used to support conservative positions. Unlike fundamentalists, traditional approaches appreciate both the human involvement in the authorship of Biblical books and the historical/literary process through which the books were developed. However, although they acknowledge this human and historical process they do see it also as inspired by God as they recognise that there is something distinct and authoritive about the canon of scripture. Hermeneutics is the science, as it is guided by rules, and the art, the application of these rules, of Biblical interpretation. The description of Hermeneutics as the ‘art of understanding’ comes from a 19th century theologian, Fredrich Schleiermacher. In interpretation, we approach a text, with either, some kind of prior understanding, prejudgement or a pre-conceived idea in order to read out of the text, known as exegesis. Or openly reading the text, to discover something about it which we would not of known before, known as eisegesis. Eisegesis, is most faithful to text, as you have no opinion on the text at hand, however this is also most confusing as it results in a variety of information. One major scholar, as mentioned, is theologian Friedrich Schleiermacher, a founder of modern Hermeneutics, which within his work Biblical teachings are emphasized. Schleiermacher was the first person to introduce a philosophical theory of interpretation, which is appropriate to the Bible along with other texts. He emphasized the affective or emotions as a source of religious experience which is ultimately different from the purely rational approach of philosophy. Schleiermacher also argued that what makes Christianity very special is the historical event of Jesus whose life was one of perfect God-consciousness. It is this which the early authors attempted to capture in their writings. Schleiermacher believed that as religious propositions can only be made known through language the role of Hermeneutics is to unlock the original experience. Using Kant, Schleiermacher argued that the mind seeks to organise different experiences, which can be seen in the different categories or styles of literature contained within the Bible. One of the purposes of hermeneutics for Schleiermacher is to therefore ensure that the right literary genre is applied to the text. Another major scholar along with Schleiermacher is Paul Ricoeur a great philosopher of the 20th century. Unlike Schleiermacher Ricoeur argued that the author is not important in interpretation of texts, only the reader as he develops a view of the world which is enriched and enhanced through his engagement with the text. Ricoeur established between semantic meaning, what the text says, that can me verifiable and the symbolic meaning, what the text means. It is this symbolic meaning which is the purpose of hermeneutics, as symbols go beyond language to the world itself and to human truths and human experience. Ricoeur argued that in modernity the message of symbols have been forgotten, so the hermeneutical task is to restore the original meanings to symbols. Hermeneutics is therefore the philosophy of finding meaning in life; language not only conveys meanings but Meaning of existence. The world itself, it can be argued, may be considered a text in which we can find the meaning; however the advantage of a written text is its existence which makes it independent from an author and his culture therefore allows us the freedom to question it but to also be questioned by it. However we do not need to believe in the world that the symbols of the text refer to, but we can participate as we have the imagination to do so. Therefore the goal of hermeneutics is the understanding.

The Duty of Integrity

The Duty of Integrity Free Online Research Papers The National Association of Legal Secretaries states that members of their association shall maintain a high standard of ethical conduct and shall contribute to the integrity of the association and the legal profession. ? The ABA’s rule 8.3 requires lawyers to report ethics violations of other lawyers or judges in order to maintain the integrity of the profession. Also known as Fink Rules, these rules require any legal professional who possesses unprivileged knowledge or evidence that is not confidential to reveal that knowledge to the appropriate authority when asked. When it comes to paralegals, The NFPA requires a legal professional to report professional misconduct even when there is no inquiry. The Fink rules still apply to the non-lawyer, so information that is protected or confidential should not be reported. The NFPA Model Code states that a paralegal shall advise the proper authority of any non-confidential knowledge of any action of another legal professional which clearly demonstrates fraud, deceit, dishonesty, or misrepresentation. Ultimately, there is no statutory or case authority that specifically extends this duty to a non lawyer legal professional. However, there may be times when you feel that reporting some ones misconduct is the right thing to do. When deciding if it’s the right choice you may want to consider if you have all of the facts about the situation, if your state protects whistleblowers, and how much do you really need your job. ? If the decision is made to report misconduct, it’s important to go to the right authorities. Within a firm or corporation there may be someone in charge of handling allegations of misconduct, and the problem can be resolved within the firm. Otherwise, the state bar, district attorney, or attorney general may be the proper authority depending on the extent of the misconduct t and who the wrongdoer is. Never disclose alleged misconduct to the client, only to the proper authorities to ensure that the public interest will be protected. ? Also under the duty of integrity is the duty to make the law better. ABA’s model rules encourage legal professionals to be active in law reform and legal services organizations. Working in the legal field you’ll come across case law that is outdated or doesn’t serve the public’s best interests. You’ll come across statues that are vague and may have unintended consequences. As a legal professional you not only have a duty but you have an opportunity to make the current laws better for the good of the public. The primary goal of the rules of ethics and the duty of integrity is to protect the public. As paralegals we are required to maintain the high standards of professional conduct and encourage others to do the same. As a legal professional you should be controlled and dignified and refrain from all illegal and morally reprehensible conduct, to maintain public confidence in the legal profession. Although it is not mandatory or considered the duty of a non lawyer to report misconduct, we all have the duty to protect the public trust. Source: Ethics for the legal professional (Deborah K.

Comment on the dramatic techniques of Alan Bennett in A Cream Cracker Under the Settee Essays

Comment on the dramatic techniques of Alan Bennett in A Cream Cracker Under the Settee Essays Comment on the dramatic techniques of Alan Bennett in A Cream Cracker Under the Settee Essay Comment on the dramatic techniques of Alan Bennett in A Cream Cracker Under the Settee Essay Essay Topic: Literature A Cream Cracker Under the Settee is a monologue, which is a play with a single character. The character is Doris, a seventy five year old widow, who lives on her own. She has home help that visits once a week. In this monologue form, information is gradually revealed by the one character Doris. We find out shes had an unhappy life; eventually we find out why. Doris looks back nostalgically on her childhood and early marriage, the times in her life when she was truly happy. Something changed her life. At first the reader is unaware and even misled by Bennett. Doris describes Wilfred as dad, and thus he misleads the viewer into thinking there was a baby. We later find there was a baby, but it was a stillbirth. Doris didnt like the midwifes attitude when she wrapped the baby in newspaper then put it in a shoebox. Doris felt she was treating it like dirt. She says, He wasnt dirty, little thing. This could have been the start of Doriss hygiene obsession. Also, Wilfred did not help her much. Her husband wanted to get a dog instead. Her marriage wasnt great, Wilfred was a dreamer and frustrated Doris. Wilfred started little projects like an allotment, but never did anything with them, and then he moved onto something else. Doris still misses him though. We know this because she talks to the wedding photo, which also shows she is lonely. We know Doris has had an unhappy past: she is also having an unhappy present. There is an immediate problem. Doris has been dusting and had an accident, she hurt her leg and its getting worse. Part of Doriss unhappiness is her loneliness, she has no family and no friends: we were always on our own. Me and Wilfred. We werent gregarious. This is exacerbated because Doris hasnt moved with the times; she doesnt like change and new social patterns. Doriss main cause of unhappiness is her home-helper Zulema. She patronises Doris and keeps threatening her with Stafford House. Doris feels she is a prisoner, referring to the Zulema regime. All the information I have considered is gradually revealed to the audience using a number of dramatic techniques. Doris uses non-standard English, like thems her leaves. She also has a local dialect and uses words like squatting instead of placing. This establishes her character: she is probably working class but when she uses words like surreptitious and gregarious Bennett suggests she is quite clever. Bennett emphasises things about Doris by using recurrent themes. Doris has a hygiene obsession. She talks about cleanliness a lot and is prejudiced against people in Stafford House because she thinks they are unclean. She talks about her husband Wilfred frequently and speaks to the photo of him. Another technique Bennett uses is reported speech: this brings in other characters so the monologue is more interesting. An example of this is Zulema we form our impression of the character from what Doris tells us she says: youre on trial here. Sometimes Doris has an imagined conversation where she plans what shell say to Zulema: dont Stafford House me. Doris does this because she would like to say it, but really she wouldnt dare. Bennett also uses direct address where she speaks to the audience. She says, Would you credit it? This is to get more involvement from the viewers. A cream cracker under the settee was written for television, so it uses a number of dramatic techniques to do with performance. These include, set, costume, lighting and music. The set gives the audience important information at the start of the monologue about the character and the plot. The set is old fashioned. The carpet is brown and beige and patterned, the room is dull with few ornaments, and this could mean she is poor. Right away you can tell something has happened: there is a buffet on its side and a cracked photo on the hearth, and Doris has a duster in her hand. The costume used is old fashioned which reflects Doris. She has a blue floral frock which she says shes had for years. She wears a pink knitted cardigan, horned rimmed glasses and tights. All these are very practical clothes. Another technique used in the performance is the lighting. In the morning Doris is sitting in front of the window and she is backlit. When she is against the sideboard she is away from the window so it is less bright. Doris later moves to the door where it is darker still. In the evening she is sat by the sofa and the room is orange due to the streetlights. There are two dramatic functions of the lighting. One of them is to indicate the passage of time. Doris does not tell the viewer what time it is. The second is as a metaphor: the last stage direction is light fades, and this could indicate Doriss death. The last two dramatic techniques of the performance are the use of music and the camera. At the start the music sounds sad and lonely this sets the mood straight away as it is depressing. The instruments are piano and brass, solo instruments that are alone, like Doris. There is a single camera which is linked to the music, zooming in to emphasise emotional moments. The camera does not move around Doris so any movement is effective.

One cannot successfully ignore such a significant theme in life as sex. Eve n a small child soon becomes conscious that his queries are being shunted aside in the most unsatisfying manner. But this does not allay his curiosityit merely intensifies it. He perceives that on certain subjects, which he did not know were different from any other subjects, his guileless questions produce a strange result on his parents. They seem disturbed, even shocked, and he doesn't know why; they will help him satisfy his curiosity on every subject but one. He soon realizes that he must look elsewhere for his information, for he must have it; it must be very interesting, or his parents wouldn't act so mysterious about it. His determination to know takes him to every source he can find, and so the typical method of acquiring sex information has begun. From tough boys, from the crude jokes and smutty stories of men, and sometimes from oversexed girls he picks up his information bit by bit, the whole often forming a most amazing mosaic. Such is the inevitable result of attemptin g to place sex in a special category by itself, something that is powerful but shameful, about which it is necessary to know yet about which one must not be taught. Such tactics automatically engender a curiosity far out of proportion to that felt about other factors in life, thus magnifying enormously the very thing parents sought to minimize. We can now perceive why Galloway was right when he said that sex education is more a matter of psychology than of biology, for our sex attitudes determine our whole physiological treatment of sex. The sex facts that children find out surreptitiously are not very important, but the emotional responses that develop are extremely important. Boys and girls who get their sex knowledge on the street frequently carry all through life the shame and fear reactions so commonly associated with certain words and actions. The mental images that they would forget are stamped indelibly upon their memories, making them ashamed to converse naturally on subjec ts properly related to sex. They may become overly self-conscious in the normal associations with the opposite sex, fearful lest some words of double meaning be wrongly interpreted. Such a preoccupation with unwholesome sex patterns often carries over into marriage, marring the relationship from which so much joy was rightly expected and proving the statement that sex education, in its end result, is marriage education.

Plate Tectonics and Weathering and Erosion Essay

Plate Tectonics and Weathering and Erosion - Essay Example Some territories of our planet suffer from annual earthquakes constantly, but it does not mean that population of these regions has got used to such events. In reality unpredictability and dreadful consequences of any natural disasters keep people in tension and fear, proving the fact that human life is fragile and unsecured. The main causes of earthquakes are the following: breaking of frail rocks and formation of hollow spaces in the Earth’s crust; volcano’s eruption; movement of tectonic plates, which collide with each other, causing heavy pushes. Making precise prognosis concerning the impending earthquake has been always rather complicated, however, nowadays scientist with a help of special equipment and methodic try to enhance people’s awareness and safety. Frequently, studying animals’ behavior can be very useful, due to their strange reactions before earthquakes. Hence, dogs start to wail and cats become more aggressive and even frantic. Noticing s uch changes in animals’ behavior, person gets opportunity to prepare himself for inevitable event. According to this, it is important to fix all furniture in the house and lay in a supply of primary necessities.

Culturally relevant teaching in the American educational system Assignment

Culturally relevant teaching in the American educational system - Assignment Example This research will begin with the statement that the documentary Beyond the Bricks offers a very candid snapshot of the systemic failures of the American educational system in regards to relating to African American students. In retrospect over fifteen years ago a literary work The Dreamkeepers: Successful Teachers of African American Children† highlighted a similar set of circumstances and proposed systemic changes that could be made to the educational system to better relate and teach African American children.   Beyond the Bricks was released in early 2009; it focused on the goal of promoting solutions for a critical problem in American schools: the consistently low performance of African†American boys in the public education system. The documentary chronicles two African† American students Shaquiel and Erick as they struggle to succeed in the Newark, NJ public school system.   Unlike, other film portrayals of Black youth which introduce a philosophy grounded in the negative imagery associated with ‘blackness and maleness’ in America, Beyond the Bricks offers a view of the Psycho-social trappings of the stereotyping within the system and its ultimate failings.   Though the film focuses primarily on Shaquiel and Erick, the issues addressed extend universally throughout all African American communities. Beyond the statistics are the real stories of students like Shaquiel and Erick who must fight the indifference of the system to build a better future for themselves.

Health Care Communication Methods Essay Example | Topics and Well Written Essays - 1250 words - 1

Health Care Communication Methods - Essay Example This is a very effective method because the administration is assured that the message has reached the right people. In addition, the people would be given a chance to air their grievances which must be incorporated in the overall strategy so as to reduce the level of resistance. Furthermore, face-to-face communication method provides the administration with a platform to observe and note the real reaction of the people who are involved in the whole process. The people are the one to be affected by the process. As a result, they are likely to give out very crucial suggestions that may make the process to be more smooth and friendly. One of the major disadvantages of using this method of communication is that it is expensive and requires a large number of subordinates in order to pass the information to all people. The organization need to train them in order to ensure that the information passed is credible and according to the expectations of the administration. The method is also e xpensive. Hiring and assigning these educators is an expensive affair which might affect the overall performance of the organization (DuPreÃŒ , 2010). Therefore, when it is undertaken, the administration must have considered all the other available methods of communication. Another disadvantage is that it is time consuming. The population that will be affected by the changes is very large. Reaching all of them would be a very hard task that will take time. In addition, some of the people may need more time in order to understand the whole concept. This may delay the process, an aspect that might affect its success. Therefore, other methods should be given the first priority. This is still an effective method of passing information to the people. The health care organization involved can post an advert in the local dailies. However, before this strategy is used, a research should be conducted to study.

Current home to your dream home - Essay Example This paper basically offers distinctions between my current home and dream home. I currently live in the sunny Florida, and this place does not fit the credentials of my dream home. The house is not big enough. The whole property is fit on a 2500 square fit piece of land which seems to be very congested. The house is not well furnished, cooled or heated. The living room according to me is too small. It is difficult for all people in the house to get along in this single room.It is also hard to do anything because the dining area and the kitchen a put as part of this space. My current kitchen does not help the situation; it has an in-built refrigerator, gas range, wall oven and dishwasher. This does not fall in my hallucinations about my dream kitchen. The number of bedrooms in this house is not enough, we are even afraid to have guest over because we cannot comfortably fit and squeeze in a guest this literally frustrates me. My outdoor is â€Å"pathetic† having only a small place to lounge beneath a palm tree by the pool is all I can say about it. This ho me is basically below my dream expectations. My dream home should be in Winter Park, Colorado, a skiing town that just mesmerizes me. The house should be big, perfectly fit on at least 7000 square feet, well furnished, cooled and heated. My dream living space is composed of a great room and other important areas such as the gaming or media room and the living room itself. A dream house must have a great kitchen and my dream kitchen should have every appliance imaginable, double ovens, dishwashers, a refrigerator and all the necessary utilizable machines should be at my disposal. The bedrooms should be big and spacious with the master bedroom fit with its own bathroom. The house should be able to accommodate comfortably around ten people and have extra space to squeeze in a couple more people. I would also prefer if the house had a separate guest

Posttraumatic Stress Disorder - Essay Example g the most severe symptoms being those whose terrifying experience was the result of a deliberate action on someone’s else’s part, such as a mugging, a rape or child abuse. When exposed to threatening or brutal emotional and/or physical treatment, wives and children experience traumatic stress disorders that require exceptional coping skills. Instances of domestic violence are usually unanticipated and uncontrollable which serve to devastate a family member’s sense of wellbeing and security. Negative effects that could damage a person’s psyche for a lifetime may result from a one-time occurrence and worsens from prolonged exposure to traumatic experiences involving family violence. â€Å"With repeated exposure to traumatic events, a proportion of individuals may develop Posttraumatic Stress Disorder. Most people who suffer from PTSD (especially, in severe cases) have considerable interpersonal and academic and occupational problems† (Meichenbaum, 19 94). For a more comprehensive understanding of the effects of Posttraumatic Stress Disorder, or PTSD, its effects upon perhaps society’s most vulnerable population, its children, will be explored. Long-term exposure to depression and anxiety could become a symptom of domestic violence in both the mother and children which could lead to posttraumatic stress disorder. â€Å"A clinical concern for both mother and children of domestic violence is the potential for the development of posttraumatic stress disorder. This is a serious anxiety disorder owing to exposure to or witnessing of events that threaten life or injury and evoke intense fear of helplessness† (Chemtob, 2004, p. 210). The condition was first recognized in battle-weary soldiers, but has since been identified in several other life occurrences, such as domestic violence. Posttraumatic stress disorder (PTSD) develops following direct personal experience of a traumatic event, witnessing a traumatic event and/or experiencing an event that

Texas Parks and Wildlife Research Paper Example | Topics and Well Written Essays - 2500 words

Texas Parks and Wildlife - Research Paper Example Currently, the Texas parks and wildlife department has several responsibilities. These include managing and conserving states natural resources and providing the public with opportunities and access to fish and wildlife habitats. Background information and history The Texas Parks and Wildlife Department (TPWD) was created in 1983, following the merger between the State Parks Board and the Game and Fish commission. However, its formation can be traced back to 1879 when fish commissioner’s officer was first established as a state agency in 1879. In 1983, the department was authorized to oversee all the resources both fish and the wildlife in all counties of Texas. The authority was given after the Wildlife Conservation Act was approved by the Texas legislature. Several historic sites that were under the management of Texas Parks and Wildlife earlier were reassigned to the Texas historical commission on 1st January 2008. In 1879, the governor was authorized to appoint a fish comm issioner by the 16th legislature of Texas. The governor appointed the commissioner to a term of two years after being approved by the senate. This appointment was to ensure that the Act for fish preservation was carefully complied with. In addition, it was meant to ensure that fish ladders and fish ways were constructed. The Fish Commissioner’s office came to being in 1881. ... The commissioner was also given powers to appoint his deputy commissioners. In 1907, the responsibilities of Commissioner’s Office were expanded. It also covered protection of wild birds and wild game. Therefore, commissioner was renamed Game, Fish, and Oyster commissioner. Fish and Oyster Commissioner’s Office was made up of three members. In 1972, the number doubled to six members. By 1983, the commission was made up of nine members who were appointed by the governor and approved by the senate. The commission members are office bearers for overlapping six-year terms. The governor appoints the chairperson of the commission biennially. The meetings of the commission are normally quarterly. However, when required they meet on a regular basis. The major responsibility of the commission is to acquire the appropriate rules and policies that play a significant role in conducting the various parks and wildlife department programs. Location and management of the Texas parks an d wildlife department TPWD headquarters is located at 4200 Smith School Road in Austin, Texas. Both the regional and field offices are established in different parts throughout the state. Those who are not working with the headquarters in Austin are known to be seventy-six percent of the total department staff. The management and coordination of all the policies and programs that concerns personnel is done in the Austin headquarters, Human Resource Division. A commission that comprises of nine members governs TPWD. The governor appoints the commission. The major responsibility of the commission is to adopt appropriate rules and regulations. This will be used in various

Index Terms Static Var Compensator, Profile Voltage, ETAP Power Station, 70kV-150kV Transmission System. IN RECENT YEARS, the needs of the electric power system in Indonesia continues to increase along with the demand for electricity and the increase in population and industrial electricity consumption. In this case the development and construction of new plants and transmission lines are needed to meet the needs of the growing burden. Akantetapi it is determined based on the consideration of environmental and economic factors. In addition to the prohibitive cost, the construction of new transmission lines also require a very long time[1].So there is an alternative to maximize the utilization of transmission lines, one of which is by using equipment Flexible Alternating Current Transmission Systems (FACTS)[2]. FACTS devices of several types of devices, Static Var Compensator (SVC) is widely sudah digunakan around the  world, including in Indonesia itself has been applied in the GI Jember. Based on the standard PLN, the voltage value allowed on electric power system ranging from 0.95 to 1.05 pu of nominal voltage[3]..SVC Can maintain the stability of the voltage remains constant at a value nominalnya by injecting reactive power into the system can be controlled. Installation SVC at one point or some places could increase the value of the voltage profile and reduce power losses (losses)on the power system[4]. FACTS concept device was introduced by the Electric Power Research Institute (EPRI) in late 1980. Where the FACTS device can increase the capacity of the transmission system and control the flow of power (loadflow)is flexible[5].On the other hand FACTS devices can also reduce the cost of electrical energy generation and improve voltage stability of the transition state(transient)[6] [7]. Therefore, this paper will discuss the placement and the determination of optimal capacity SVC for voltage profile improvement 70-150 kV using Genetic Algorithms in the software ETAP Power Station A. System Modeling Electricity Modeling electric power system is defined as a network system consisting of components or electrical equipment such as generators, transformers, transmission line, and a load interconnected and establish a system.[8] [9] B. Generator model Generatorsare modeled as a PV bus. Which generator terminal voltage at a constant value. This is because the generator using AVR (AutomaticVoltageRegulator) to regulate the voltage on the bus. On the bus references (SlackBus), generator dioprasikan by rating voltage and phase angle const ant. In mathematical equations active power (MW) and reactive power (MVAr) generated by the generator can be written as follows: (1) . (2) Where: Pg and Qg=Active and reactive power is delivered terminal generator. Vt = terminal voltage generator ÃŽÂ ´ = generator phase angle Eq= internal voltage generator Xd and Xq = synchronous reactance C. Power Transformer Power transformer of the power system can be expressed mathematically by the equation: .. (3) (4) Where: E = Voltage (pu) F = frequency N =Number of turns = maximum fluxsi From the equation it can be seen that the mechanical power transformer primary and secondary winding is not connected, but electrically interconnected by electromagnetic induction. D. Transmission Line Transmission lines are represented in accordance with the class of transmission. Representation of the transmission line based on the distance is divided into three parts, namely: 1. Short Transmission (l km / 50 miles) 2. The transmission medium (80 km / 50 mi 3. Transmission length (l> 240 km / 150 miles) Figure 1. the equivalent circuit transmission line short Figure 2. the equivalent circuit transmission line medium and length of Short the transmission line, has a channel length of less than 80 km (50 miles) assumed that the capacitance value can be ignored and only the taking into account the value of the resistance (R) and inductive reactance (XL).With assumed in a balanced (balanced), the transmission line can show by using the equivalent circuit of the phase with resistance value (R) and inductive reactance (XL)which are connected in series (series impedance), which can be seen in Figure 2.1. While in the middle of the transmission line, the transmission line has a length of 80 km (50 miles) and 240 km (150 miles). In the middle of the transmission line, the capacitance conductor can not be ignored so that the conductor can be modeled using the equivalent circuit of one phase in the form of nominal à Ã¢â€š ¬ which can be seen in Figure 2.2. But for a long transmission line, capacitance and impedance conductive assumed contained on all the conductors to the limit of infinite. E. Electrical load In power systems, there are two kinds of modeling the load is static load and dynamic load. 1) Model Static Load Static load model is a model that represents active and reactive power as a function of the bus voltage and frequency. Static load in response to changes in voltage and frequency is reached quickly, so it tends to steady-state condition. Static load models are typically used for components such as resistive loads and lighting loads, and is also sometimes used to approach the dynamic components. 2) Model Load dynamic Dynamic load model is a model that represents the active power and reactive follow the dynamics of the system variables, so that the condition can change at any time. F. Drop Voltage The Drop Voltage is the amount of voltage that is missing on a conductor. The voltage drop across the power line is generally proportional to the length of the channel and the load, and inversely proportional to the cross sectional area of the conductor. The magnitude of the voltage drop expressed either in percent or in the amount of Volt. G. Static Var Compensator Static Var Compensator or called SVC is one of the FACTS equipment Device consisting of a reactor component with a large set of inductive reactive power compensation and capacitor as a source of reactive power, power electronics equipment as well equipped as a switching device. Broadly speaking, the function of which is to preserve SVC (controller) voltage stability remain constant at its face value. SVC is a generator / load connected shunt static VAR where output is set for the exchange of inductive or capacitive currents in order to maintain or control the power system can be varied. TCR (Thyristor Controlled Reactor) at the fundamental frequency can be treated as a variable inductance . (5) Where, XV is a variable reactance SVC while XL is the reactance caused by the fundamental frequency without control thyristor and ÃŽÂ ± is the angle of ignition so that the total equivalent impedance of the controller can be expressed in: .. (6) Value rx = XC / XL is given by the controller limit ignition angle limit of value fixed in accordance with the design. control law The steady state contained in the SVC typical VI characteristic figure 2.3 is .. (7) where V and I are rms voltage and current magnitude and Vref is the reference voltage. Typical values for slope XSL is 2 to 5%, tehadap SVC base; The value is necessary to avoid passing the limit of bus voltage variation is small. A typical value controlled voltage range of Vref.[11] [12] Figure 3. V I characteristics instate SVC steady H. Power Flow method By using the Newton Raphson method to analyze the power flow by forming a non-linear algebraic equations of power flow calculation can be determined by performing a comparison between the voltage change in voltage angle and the magnitude of the voltage with active power changes and reactive power (k)).[11]In the mathematical equations of power flow can be written as follows: (8) Where: is the value of active power (MW) is the value of reactive power (MVAr) I. Software ETAP Power Station ETAP (Electric Transient and Analysis Program)is a software full-graphics that can be used to design and test the condition of the existing electric power system. ETAP can be used to simulate the electrical power system offline in the form of a simulation module, monitoring the operation data in realtime, simulation, real time system optimization, energy management systems andsimulation of intelligent loads hedding. ETAP is designed to handle a variety of conditions and electric power system topologies both in the consumer side of the industry as well as to analyze the performance of the system at the utility. software Thisis equipped with facilities to support the simulation of such networks AC and DC (AC and DC networks),the design of cable networks, grid earth (groundgrid), GIS, panel design, arc-flash, coordination of protective devices (protective devices coordination /selectivity),and AC / DC control system diagram. ETAP Power Station also provides a library that will simplify the design of an electrical system. library This can be edited or can be added to the information equipment. This software works by plant (project).Each plant must provide modeling support equipment associated with the analysis that will be performed. For instance generator, load data, channel data, etc. A plant consists of a sub-set of the electrical system that require special electrical components and interconnected. In Power Station, each plant must provide a data base for that purpose. ETAP Power Station can be used to describe a single line diagram graphically and conduct some analysis / study of the Load Flow Short Circuit, the motor starting, harmonics, transient stability, protective device coordination, and Optimal Capacitor Placement.[13] A few things to note in working with ETAP Power Station are: One Line Diagram, shows the relationship between the components / equipment so as to form an electrical system. Library, information about all of the equipment that will be used in the electrical system. Data electrical and mechanical equipment details / full can simplify and improve the results of simulation / analysis. The standard is used, usually refers to the IEC or ANSI standards, the frequency of the system and method the method used. Case Study, containing parameters parameters related to the method of study to be performed and format of analytical results. Completeness of data from each element / component / electrical equipment on the system that will be very helpful analyzed the results of the simulation / analysis can approach the actual operational state.[13] J. Genetic Algorithms on OCP tool within ETAP Optimal Capacitor Placement (OCP) is one of the tools in the software ETAP Power Station which uses genetic algorithm for optimal capacitor placement. Genetic Algorithm is an optimization technique that is based on the theory of natural selection. An algorithm starts with the generation solutions with the diversity to represent the characteristics of the overall search space. By mutation and crossover characteristics that both have to be taken to the next generation. The optimal solution can be achieved through repeated generations. The most common method is based on a rule of thumb followed by running multiple power flow studies for fine tuning size and location. multiple power flow for fine tuning size and location. K. Objective Function The objective of the placement problems SVC is to improve the voltage profile and reduce the total power losses in power systems installed. The objective function is obtained from two terms. The first is the placement of SVC with the approach of the capacitor and the second is the total power loss. The objective function associated with the placement of the capacitor consists of a total power loss and the capacity of the capacitor. In general, the optimal capacitor placement and capacity can be written in the following equation [14]: .. . (9) Subject to: .. (10) .. (11) Where: P loss= Total power loss J = Total Bus = Placement capacity capacitors on the bus j Vj= voltage rms at bus j V min= minimum voltage is allowed (pu) V max= maximum voltage that allowed (pu) = maximum capacitor capacity permissible = minimum capacity capacitor bank L. Operatinal Constraint Along the feeder are required to remain within upper and lower limits after the addition of capasitors on the feeder. Voltage constrains can be taken into account by voltage. M. Placement of Static Var Compensator placement static var compensator used approach OCP. OCP is the optimal capacitor placement that exist in software ETAP power station which will be described in research methodology. Optimal placement of capacitors in the power system has many variables including the capacitor capacity, optimal placement, voltage and harmonics. Where in determining placement and optimum capacity, types of capacitors can be adjusted based on conditions on the ground. Namum considering these variables, making optimal placement becomes very complicated. So as to simplify the analysis, the type of capacitor can be assumed as follows: 1. The system is in equilibrium (balanced) 2. All types are considered constant load N. Capacitors Capacity Capacitors In determining capacity, used capacity started based standard smallest capacity of capacitors and multiples thereof.

Building a Portfolio for Retirement Essay -- Economics

Building a Portfolio for Retirement â€Å"According to a survey conducted by the Savings Education Council last year, 24% of all workers were not confident that they were prepared to retire comfortably.† Upon retirement we would like to maintain a certain level of income and lifestyle such as that established in the prime of our earning career. Through proper planning this goal can be achieved. I am going to establish the need for investments/ savings through the life-cycle model of consumption. I will then walk through standard retirement plans showing that additional funding will likely be needed for the upper-middle class, leading to stock and bond investments, risk tolerance of an individual investor, how that affects diversity and rates of return. On average Americans save approximately 5% of their earnings. This is the lowest among industrialized countries; Japan saves on average 24%, they are the highest savers. The US saves so little in part because of the availability and ease of credit, the financial system; as well as an effective Social Security system. However, the US is changing, to depend on today’s Social Security for tomorrow alone is a risky venture to say the least. Throughout one’s career their earning levels will fluctuate; the highest level of earnings is most likely achieved around middle age or mid-career. It is at this time most Americans begin to think about retirement and savings. The life-cycle model of consumption indicates that we desire a constant level of consumption throughout our lifetime. We, therefore, will go into debt when we are young, repaying the debt and begin saving in middle age, and dissave in retirement. While I personally believe that savin... ...o fund banks in the big picture of money. My 95-year-old Grandfather has successfully funded his retirement through CDs, a pension, and Social Security. To this day he still invest in CDs and his net worth is six figures. In large, most investors do not want to do the research in selecting stocks, bonds, and money market accounts for their portfolio themselves; at the prime of their career they may not have the time either. A managed fund is an appealing option. A managed fund may cost slightly more, there are management fees involved, typically not more than 2%. Picking a fund lessens the workload, pick a well know fund such as Janis, Fidelity, USAA, Templeton, Putnam, etc. If you have the money, pay someone; an investment fund manager who will take into account who you are. The name on the fund you choose is not so important as they type of fund you choose.

Herman Miller Business Case Essay

1. Executive summary Herman Miller, an environmental leader in the office furniture industry that offers a wide variety of products including seating, systems furniture, filing storage, desks, tables and health care. In 1989, the company decided to adopt a triple-bottom-line philosophy, so it established and changed company’s environmental direction by adopting â€Å"Perfect Vision† initiative that targeted zero landfill, zero hazardous, waste generation, zero air and water emissions. In 1997, the company decided to implement a cradle-to-cradle (C2C) protocol based on eco-effectiveness vs. eco-efficiency and Waste equals food; which consisted of four key elements: biological and technical nutrients; green-yellow-orange list disassembly, recyclability and recycled content. The C2C approach focused on minimizing toxic pollution and reducing natural resources waste. After years of extensive work, in 2001, the company decided that it was time to implement a C2C design protocol on a product that would contain recyclable materials from beginning to end; Mirra chair project was launched. Herman Miller worked toward the design process, manufacturing, engineers, supply chain managers, manufacturing associates, design consultants, trained over 300 employees, worked with suppliers to find substitutes eco-friendly materials, performed raw material assessment, met with people from sales and marketing and discussed several options for closing the loop by recycling the material from Mirra chair. The major issue the company faced was determining the material that was going to be used for the arm-pad skin: polyvinyl chloride (PVC) versus thermoplastic urethane (TPU). PVC was known to be inexpensive and provided to be durable, scratch resistant and soft; but violated the standards of the C2C protocol. PVC had bad press due to its toxicity during manufacturing process and when it was burned or incinerated. In contrary, TPU showed that had acceptable quality characteristics; prove to be even more scratch resistant than PVC, but raw material cost was twice of PCV. Development and supply chain management teams preferred to proceed with PVC while the design for environment (DfE) team wanted to press forward with TPU. 2. Introduction 2.1 Company background Herman Milller was founded as a Michigan Start Furniture Company in 1905. In 1923 D.J. De Pree purchased it, renamed it after his father-in-law and grew the company into an internationally acclaimed furniture design house. Herman Miller is considered as one of the top four suppliers in the US office industry that offers suite office furniture including seating, systems furniture, filing, storage, desks, tables and healthcare furniture. In 2001 annuals sales were about $1.5 billion dollars. In 1989, the company decided to move toward environmental sustainability by changing company’s environmental policy and direction by adopting a cradle-to-cradle (C2C) design protocol for environmental sustainability. The cradle-to-cradle approach will emulate nature regenerative cycle at the end of the life cycle. C2C redesigned industrial processes by minimizing toxic pollution and reducing waste. In 2001, a Design for Environmental (DfE) team was formed to design and develop a new product. Mirra chair would be the most advanced and complete application of the C2C design protocol among any product manufacturer to date. 3.2 Identification of key issues facing the company * In 2002, the company suffered a decline in sales due to economic crisis and pre-internet-bubble where many of its customers cutback or dissolved. * The company realized that the ways its products were designed generated waste in the production process. * Cradle-to-grave process used by the company at the time, released toxic material into the environment. * Products were useless waste at the end of the useful lives. * The major key issue that the company faced when launching the design protocol of Mirra chair was to decide the type of material that was going to be used for the arm-pad skin: polyvinyl chloride (PVC) versus thermoplastic urethane (TPU) * Another relevant issue was the collection of Mirra chair after the end of its life cycle. DfE team were evaluating three alternatives: Herman Miller to collect chairs; retailers to collect the chairs; third party company would collect them or customer could return them directly. 3.3 Issues facing the company and/or industry * Herman Miller international market was significant. Most of Herman Miller’s customers were multi-national; therefore, tighter environmental regulations contributed to realize that the company needed to change its sustainability approach in order to stay ahead of the industry standard. * Moving toward environmental sustainability implied to review and redesign industrial processes that would generate less toxic pollution and deplete natural resources. 3.4 Opportunities for the company * Leader of residential, office furniture and workspace design. * One of top four suppliers in the U.S. office furniture industry. * Company offered innovative good designed and high quality products. * Sustainability strategy was one of their competitive advantages. * Company stay ahead of the game by setting new industry environmental standards. 3. Problem identification and analysis The company analyzed that the way their products were designed using the cradle-to-grave process released toxic material into the environment and generated waste that could be minimized or avoided. Tighter environmental regulations help to realized that in order to stay ahead of the game, they needed to change cradle-to-grave for a cradle-to-cradle process. In 2001, Herman Miller decided to implement a design protocol on a product from beginning to end, so Mirra chair project was chosen. In order to implement C2C protocol a DfE team was formed to develop environmental evaluation measures of the new product, redesign and change processes, create a database for suppliers’ materials using the Green-Yellow-Orange-Red list criteria and establish disassembly guidelines for the new product. Engineers, supply chain managers, manufacturing associates and design consultants worked together to change their processes. Over 300 employees were trained on the new design protocol. The design process was the first one to be reviewed. During the exploration phase, designers brainstormed on the basic concept of the product and outlined high-level specifications. Once the basic design was established during the development process, the product was divided into modules and different teams were assigned to each module. Each team developed a prototype of their modules, DfE team assessed the design, following the C2C protocol for material chemistry, disassembly, recyclability and recycled content. Scorecards (See annex 1) were created and feedbacks were communicated to the development team. The final DfE assessment (Annex 2) aggregated the material chemistry, disassembly, recyclability and recycled content scores for all modules and a scorecard for the final product was entered into Herman Miller’s material database for future reference. Each case was analyzed on a case-to-case basis; a final DfE score of at least 50% was typically required for product acceptance. Calculation of weight and scores were calculated using Exhibit 5 formulas and criteria (See annex 3a and 3b). The importance of these calculations was used to perform a material evaluation assessment. If final score were below 50%, the company would find alternate components that meet C2C protocol requirements or work with suppliers to find substitute inputs or completely new material. One of the major issues was the PVC material used for the arm-pad of the chair, it was classified as â€Å"red† material, and its final DfE score was 0% because of the toxins released during its manufacturing and disposal process. PVC is known to be extremely durable, scratch resistant, formable and cheap; but it doesn’t comply with the C2C protocol. Development engineers and supply chain group preferred PVC material because it was an inexpensive material and the tooling for the PVC arm pads had already been fabricated. Thermoplastic Urethane (TPU) was identified as an alternate and suitable material that meet the same product performance as PVC. Tests showed that TPU had acceptable quality characteristics and might be even more scratch resistance than PVC; however, raw material cost of TPU was twice of PCV and increased the cost of the arm pad assembly by approximately by 30%. To switch to TPU would cost over $100K in retooling or would try to modify the PVC tool to work with TPU. Modifications of the original tool were feasible, but it was unclear whether the part quality of the TPU arm pad skins would be consistent as the PVC skins. DfE team wanted to purse the use of TPU since it complies with C2C protocol. The closing loop of the Mirra chair was another relevant issue that concerned the company. Mirra team discussed several options of how to collect the recycling the material of the chair. Three basic options for collecting the chairs were identified: 1) Herman Miller could collect the chairs itself; 2) Retailers could collect them, 3) A third party company would collect them or 4) Customers could return the chairs to Herman Miller once they finished with their useful life or wanted to upgrade to newer chair models. If Herman Miller took the responsibility of collecting the used chairs, it would have to develop logistical support for handling the products coming back to the company. 4. Recommendations Based on environmental sustainability culture and the triple-bottom-line philosophy adopted by Herman Miller, I would recommend pressing forward with TPU material, which complies with C2C design protocol and continuous improvement policy of no inventory, no waste products and no waste parts and time. The company should promote a strong â€Å"PVC-free† marketing strategy to attract a bigger market share, taking into consideration that Mirra chair would be the most advanced and complete application of C2C protocol among competitors; and the first manufacturer to offer a product of its kind. Mirra chair project should be used as a base-line to determine the future of other Herman Miller’s products. If Mirra chair demonstrates to have a higher acceptance rate among customers, increased sales and elevated overall performance; the company should consider expanding its line of â€Å"green† products; or even switching from PVC products to PVC-free products over the course of the years. It is important to make a cost-benefit analysis comparing the two materials in order to have a better picture of the pros/cons and implications of any final determination. In addition, the company should hire a third party collector in order to avoid developing further logistical support and increase the cost for handling products coming back to the company at the end of its life cycle. 5. Conclusion Herman Miller’s corporate environmental goal was stated as to â€Å"become a sustainable business – manufacturing products without reducing the capacity of the environment to provide for future generations†. Therefore, final decision of pursuing PVC or TPU should be based corporate values and policies. The company needs to evaluate the possibility of the negative impact and consequences if it decides to launch a â€Å"green† product strategy but continues to include non-environmental friendly material on its products.
