Summary for an article of political economy subject Essay

Summary for an article of political economy subject - Essay Example Although disregarded by many, neo-liberalisation jumped the barriers into active politics establishing themselves as the best politics nationally and internationally. By 1971, United States, Australia, Britain, and New Zealand adopted these ideas to their domestic programmes. By 1980, Neo-liberalism had grown to higher levels in Britain and United states such that it sidelined Keynesianism and social alternatives. It formed the pattern that shaped all the other policies even if its rationality would still be contested. Non-English speaking countries like Japan, Germany, and Sweden thought Neo-liberal ideas as defensive to shore up the model of capitalism, which was under pressure from other successful models. Additionally, Neo liberalism model was thought as an-outdated capitalist model that lacked analytical tools to direct policies and remedies to problems. However, Neo-liberalism remained prominent on state economies of Britons and Americans. In 1990s, neo-liberalisation triumphed after the failure of public capitalists of Germans, Swedes, and Japanese. Neo-liberalism became the dominant ideology of analysing capitalism as a global network of accumulation. One paramount influence of Neo-liberalism is that it gives priority to capital as resources rather than capital as production. This way it would give the means to disengage from commitments taken up from the Keynesian era. Many politicians are adamant to keep neo-liberalisation, which makes it difficult to win electoral support by itself. Neo-liberalism has some limitations, but some of its ideologies establish a solid basis for political and economic

Heidegger`s Being and Time Essay Example | Topics and Well Written Essays - 1750 words

Heidegger`s Being and Time - Essay Example Being and Time is a book by Martin Heidegger. It was never finished but it still continues to be an influential book, in fact, it is Heidegger’s most influential book. It is so influential that it actually had a great impact on the field of 20th century philosophy, particularly existentialism. Heidegger points out the problem of â€Å"being† than reflecting on consciousness or pre-conceived notions of a particular object. His problem was that we are slaves of that pre conceived notions and his book Being and Time chronicles all of that. Heidegger claims that Western philosophy has been misunderstood ever since Platonic times. Everyone assumes something as something â€Å"to be† rather than something for what it is. Thus, the matter of the object turns to being an object rather than being the supposed object itself. His main concern is that all objects have gotten to be slaves of history and their so-called properties that we forget about the other things the object can do. With that, we also become slaves to properties as well. For Heidegger a correct investigation of things should focus on the things or elements that are the object themselves. Heidegger also says that the reason for philosophy being misunderstood is that the philosophers have overlooked the basic facts that pre-theoretical ways offer; instead they have applied those generalizations equally to all things that they are studying. That’s why the philosophy is flawed, according to Heidegger. Thus, he proposed a new way of appreciating objects. Although he understood that we appreciate things via our innate understanding of things, such as the â€Å"common sense† which is actually prone to error. This is because as humans, we are always readily affected by our beliefs in God, our logical thinking and practically the reality. This makes our relationship with objects, particularly technology and the way of out thinking affects it. Another point that Heidegger wants to emphasize is the phenomenological approach that Husserl started. T his is existentialism on its basic roots. According to Husserl, philosophy could be and should be a description of one’s experience. For Heidegger, philosophy or the understanding of experience is already embedded in the world, therefore centuries of conditioning of how we should interpret the experience are already there, making the interpretation not as unique as one would think because it is already influenced by history and other stuff. Hence, Husserl’s understanding of reality is more â€Å"intentional†. For Heidegger, describing an experience should also consider who that description is for. Anything, with philosophy, is a possibility, and therefore one should be careful in analyzing stuff philosophically. Heidegger’s ideas, however new and noble and adventurous for his time, were not as accepted well because of his affiliations. He supported Nationalist Socialism and he was actually a member of the Nazi Party. All of his supporters claim that his p hilosophy was not affected by his Nazism or vice versa. They are saying that that affiliation is irrelevant (but others claim that being a member of the Nazi Party was a personal error on his part. The book Being and Time tries to talk about the question about the sense of being and philosophizing it in a manner that the people would understand his point. According to him, â€Å"Being is not something like a being† and the things that determine a being is based on the terms that they already understand. But for him, one should be basic abut all of these things and be fundamental about it, negating any previous ideas by using logic. This is Heidegger first academic book. It was published

Language Attitudes And Ideologies English Language Essay

Language Attitudes And Ideologies English Language Essay In a contemporary society especially in a diverse country such as South Africa, language plays an important role in defining identity. As a result of the many diverse cultures, South Africans are exposed to a vast amount of different languages. These languages form part of identity and thus are accompanied by certain language ideologies and attitudes. Language ideology may be defined as shared beliefs about language forms and practices embedded in social conflicts over power (Volk and Angelova, 2007:177). Attitudes on the other hand are closely related to ideologies, and are described as learned reactions toward a person or situation (Steinberg, 2007). This essay aims to research the effects of a multilingual university (UWC) community on language use and ideology. It will also provide reasons for these effects and how attitudes relate to language ideology. To begin the study my research population consisted of a UWC male student, age twenty five and his first language is Setswana. In order to conduct the research I first posed a question to this student. The question was as follows; Given that you have been at UWC for at least two years, what effect is your membership of a multilingual university community having on your language use and ideology? The student answered that being at UWC has changed his ideology of different languages, because of the diverse language speakers and the formation of strong friendships he has been forced to become familiar with other languages. I then used this response as a framework to begin the research. As this is a qualitative research study I have made use of the survey-questionnaire method to gather my data. I have particularly applied the Linkert Scale style questionnaire that consists of statements and of which the participants answers are among the following; strongly agree/ agree/ unsure/disagree/ strongly disagree. The participant would then provide the reasons for their answers. The statements on the Linkert Scale questionnaire were as follows: I am happy with English as the main medium of instruction at UWC I would be more successful in my academic studies if my home/first language could be used in lectures and tutorials The other languages are sufficiently developed for use at tertiary level, and should not only be used for informal communication Its a good thing that we have a common language here at UWC to help us communicate across linguistic boundaries Im pleased that Ive picked up some words and expressions in other languages here at UWC The other part of the questionnaire asked for reasons for answers and provided writing space for the students response. In this case the student then provided reasons for his response to the above statements which made up the full data which I have made use of in this essay. The findings consisted of the responses to the above statements and the reasons for the response. The participants response to statement one was that he strongly agrees with English being a medium of instruction at UWC. His reason for his response was as follows Since different students come from different backgrounds/cultures and languages its only fair to have English as a lingua Franca common to all. Thus in this case I have found that the participant feels that English is a language spoken by all students at UWC. He also suggests that it is fair to have English as a medium of instruction, because all students at UWC share the common understanding of English whether it be a first, second or third language acquisition. This explains English as a lingua franca, the term lingua franca describes a language serving as a regular means of communication between different linguistic groups in a multilingual speech community Holmes (1997:86). The participant in this case is happy with the f act that English is used as a medium of instruction. The students response to statement two was that he disagrees that he would be more successful academically if his first language was a medium of instruction. The students reason for this is as follows No, I am more competent in English than my mother tongue when it comes to reading and writing as I last stopped using my first language for reading and writing in standard 3. It is clear, judging by the participants response, that he has lost proficiency in his first language in reading and writing due to being educated in English for so long. As a result of being educated in English for such a long time the student seems to feel more competent with English. This evidence gives rise to the notion that English may be the predominant language for educating a multilingual society due to its global recognition. The participants response to statement three was that he strongly disagrees with the assumption that, other languages are sufficiently developed for use at tertiary level and should not only be used for informal communication. The students reason for this is When it comes to Afrikaans and Xhosa I understand because these are the languages predominantly spoken in the Western Cape, but if its other languages it would not be fair to the other 11 official languages which are not used in tertiary education. The student in this instance feels as that English, Afrikaans and Xhosa are the only three languages developed at tertiary level as there is predominance in the amount of speakers of these languages. However, the participant disagrees that other languages should be used as a medium of instruction at tertiary level because it would be unfair to those who cannot understand the language. The student also feels that should one language, other than English/Afrikaans or Xhosa, be used as a m edium of instruction at tertiary level it would be unfair to the other eleven official languages that are not used in this way. The students answer to statement four was that he strongly agrees that its a good thing that we have a common language at UWC to communicate across linguistic boundaries. The students reason for this is as follows; If it wasnt for English as a lingua franca we would all be lost unless we share a 1st language, So it very good that we have a lingua franca as we connect/communicate well. In this case it is evident that the participant feels generally pleased that there is a language that can break through linguistic boundaries. The student in this case feels that English has the power to do so as a result of its wide range of speakers. It is also clear that the student agrees that English as a lingua franca helps us to communicate with other students from different linguistic backgrounds. The last statement the partaker responded that he agrees that he is pleased he has picked up some words and expressions in other languages. His reason for this is Yes I am this helps to communicate better with student who I do not share the same 1st language with, helps to build friendships and more, it brings people together. With regard to this response it seems that the student is pleased that he is able to pick up words form other languages that help to form relationships. To conclude the findings it is apparent that language attitudes form part of ideologies. Judging by the data I have gathered the participant provided insight of his attitude toward different languages especially English. It is obvious that English is a medium of instruction that the participant is pleased with as he would not have chosen UWC as an institution for higher education if this was not the case. The participant thus has a positive attitude towards English and the ideology (shared beliefs of language forms and practices) that English is a lingua franca common to all, increases this positive attitude. In this instance it brings to mind the assumption that we attain our attitudes from our ideologies. In essence it is apparent that our ideologies influence our attitudes toward various languages and it is these components that constitute as part of our identity. Language thus forms part of identity and in a modernised multilingual society the choice of identity is open to all. To elaborate one can side with the post-modern researchers who suggest that Post-modern accounts of identity have reacted against traditional and essentialist views by proposing an almost unlimited range of identity choices (Wallace, 2008:61). We as South Africans may be faced with the challenge of the battle between predominant and minor languages in a diverse country that consists of many different languages. Yet it is still astonishing to see that an institution such as UWC is able to bring people together even if it is through the use of English as a medium of instruction.

The Myth of Exodus Essay -- Holy Bible Essays

The Myth of Exodus There are many themes running through the Old Testament myth of Exodus – slavery, rescue and redemption, guidance, commandments on how to live, the creation of a nation, and God’s power over other gods. In this paper I will explore what appears to be the chief reasoning behind the creation of the Exodus myth – the explanation of the creation of a monotheistic religion and the similarities of the Exodus myth to the ancient myths, as well as how one should approach the reading of the myth. First of all, we need to understand what a myth is. William Bascom says in his essay, â€Å"The Forms of Folklore: Prose Narratives†, â€Å"Myths are prose narratives which, in the society in which they are told, are considered to be truthful accounts of what happened in the remote past† (Dundes 9). Trying to prove the elements in the myth as factual are contrary to the very existence of the myth. In reading Old Testament Bible myth, the question of divine inspiration versus historical truth is often debated. â€Å"A myth makes a valid statement about the origins of the world, of society and of its institutions, about the gods and their relationship with mortals, in short, about everything on which human existence depends† (Graf 3). Further, the context in which the myth was written must be taken into account when reading the story. Bronislaw Malinowski in his essay â€Å"The Role of Myth in Life† says that â€Å"The text, of course, is extremely important, but without the context it remains lifeless† (Malinowski 201). The context that needs to be addressed when reading the myth are the cultural and sociological components that surround a mythological text. This context, consisting of the understanding of the culture in which the myth exte... ...map of proper behavior for the new society that has been liberated from slavery. Within the context of history, the myth offers future generations a glimpse of a new religions beginnings. As the new code of laws is set into place, a new and more powerful god emerges – a god of great strength, a god that supersedes all other gods, one god above all others.

Personal Dilemma Paper Essay

In today’s society people face some form or type of dilemma and it could either be a personal, ethical, or moral dilemma. As individual’s we encounter personal dilemmas, whether it is professional or educational and with these dilemmas there is always some type of choice that must be made and with this choice there is either a solution or resolution or in some cases the choice that is made could either have a positive or negative effect for those involved. Within our society we are faced with ethical dilemmas on a daily basis and they come in the forms of newspapers, television, and by Internet. Some of these dilemmas could be about a Congressman/woman, Senators, Politicians, or Celebrities. For this paper the topic that has been chosen and will be discussed is Same Sex Marriage and the following will also be addressed as well: the nature of the dilemma, the ethical decision made about Same Sex Marriage, alternative course of action and why this action was taken, and th e outcome of the situation. Ethics and Morality So what is ethics and how can it affect me and the choices I make? According to Braswell, McCarthy & McCarthy (2012), ethics can be defined as â€Å"the study of what is considered to be right and wrong, good and evil†. For example, let’s say that you caught your best friend cheating on his wife. What do you do? Do you confront your best friend and give him the chance to explain what is going on or do you just ignore what you saw and not say anything to either your best friend or to the wife. This is what would be considered an ethical dilemma in which there is a conflict and that some type of choice has to be made. In this type of situation no matter the type of choice you make it could affect your best friend and his wife in a positive or negative way. Morality can be defined by Merriam-Webster’s online dictionary as â€Å"†¦a system of moral conduct† leading ultimately to the living of a moral  life (Morality n.d.). For example, if an individual is faced with a moral dilemma this means he/she not only makes the decision about the conflict itself, but as a result there could be more than one action or reason why the individual chose that particular action. Basically, the individual has to make a choice, but with this choice there could be more than one solution or resolution and the decision must benefit the greater good of society in a whole. Same Sex Marriage As little girl’s we had this fantasy of what our ideal wedding would be like and it would be that the man of our dreams would be up there standing at the altar waiting for his soul mate and best friend. This is what most little girl’s dream of, but the reality of this is the fact that most boys and girls dream about marrying the man or girl of their dreams. The idea of marriage has taken on a whole if not different concept and meaning. When one thinks of marriage it is a union between a man and woman, not a union between a man and a man or a woman and a woman. Most of us may have family members and even friends that are in a same sex relationship. For most of these couples the only thing they are wanting is to not only spend the rest of their lives with their partner, but to have it legal and recognized in the state they live in. On October 14th, 2014 same sex marriage not only became legal in 23 states, including the District of Columbia, but in the first time in our h istory President Obama gave his full support to same sex marriage stating this: â€Å"At a certain point, I’ve just concluded that for me personally it is important for me to go ahead and affirm that I think same-sex couples should be able to get married† (ProCon.org). In a decision that was made by the United Stated Supreme Court same sex couples can now be allowed to receive the same benefits as married heterosexual couples would receive. For the rest of the 20 states that have not legalized same sex marriage it would seem that there are certain laws, constitutional amendments or both prevent a same sex couple from getting married in his or her own state (ProCon.org). My Personal Belief and Reasons Why I Support Same Sex Marriage To be completely honest this issue not only hits a raw nerve with me, but I have family and friends that have been in a same sex relationship for years and have expressed to me about getting married. For example, I have a best friend, who is not only like a sister to me, but she  is considered to be part of our family. My friend and her partner live in a state where there is a ban on same sex marriage and she has expressed to me that she would like to marry her partner, but in order for that to happen she must go to another state to get married. We were both brought up and taught by our church that not only is marriage reserved for a man and a woman, but homosexuality is a sin in Godâ€℠¢s eyes. When my friend first told me of her plans to marry her partner I expressed my feelings of happiness and excitement. I have never nor will I be judgmental of my best friend’s decisions or choices when it comes to her life. As a friend I will always be supportive and I will stand with her though thick and thin. My friend and I are both bi-sexual and we are happy with our lifestyle and we do not see anything wrong with the way we live. Many times we have heard that being gay is a sin or that when we die we will not be able to go to Heaven that we are destined for a life of Hell due to our lifestyle. The dilemma in this case is that my friend and her partner do want to get married and in order to do that they must go to Minnesota, Illinois, Nevada, or New York to get married. The problem with this is the marriage will only be recognized in the state they have gotten married in and for some states you must be a resident of six month or longer in order to get married. To be perfectly honest I believe that same sex couples should be allowed to celebrate their union. If heterosexual couples can celebrate their union then why not a same sex couple? Clearly the definition of marriage has changed and people that were not fully supportive or accepting of same sex marriage are supporting the idea of same sex marriage and if same sex couples were to allowed to marry this would give them the opportunity to adopt a child and provide a stable and healthy environment for the child. In New Jersey, since making same sex marriage legal not only has the economy grown, but it has also provided new jobs and brought in additional money and with Massachusetts being the first state to legalized same sex marriage there has been a decrease in the divorce rate (ProCon.org). Reason for Decision and Outcome of the Situation With the situation of my friend and her partner wanting to getting married not only do I fully accept and support the idea of their marriage, but knowing that our government has made changes to the Defense of Marriage Act  (DOMA) is a much welcome relief and positive change (ProCon.org). With the support of the President of the United States and the Supreme Court decision that allows same sex couples to receive the same tax breaks and pension rights of married heterosexual couples this is just the beginning (ProCon.org) The next step is to lift the ban or constitutional amendments in the remaining 20 states and allow same sex couples to marry. By allowing same sex couples to marry this in no way will weaken the family values, but will only make the family values stronger and more successfully. Marriage should not be looked at as a privilege or a right, but as a reason to celebrate a union between two people that love each other not matter what their sexual orientation and the famil y unit is now being redefined as well. A family unit does consist of a mother and father, but now the family unit can consist of two mothers and two fathers raising a healthy family in a healthy environment. Conclusion Whether the dilemma you are faced with is personal, ethical or moral one thing we do know is there is always some type of conflict between the action and positive or negative consequence are made for that action or behavior. Dilemmas are personal in nature and one must find the appropriate course of action to help resolve the issue that was at hand. In the case with my friend and her partner the dilemma was simply they both wanted to get married and in order for that to happen they would have to travel to another state in order to get married, but at the same time the marriage would be recognized in the state they were married in and not the state they live in. With this type of dilemma the possibility of my friend receiving any type of benefits from her partner is looking grave and until the state lifts the ban on same sex marriage her and her partner will remain in a domestic partnership.

Hale s letter to Danforth corrected

Your Honor, Abigail Williams is nothing but a where who wants to dance with John Proctor, an extremely moral man who had dedicated his life to God, on his wife's grave. The lies that Abigail Williams has cooked up is punishment for John Proctor for taking away her innocence. She is nothing but a where who lusts for John Proctor. Vengeance is running through Salem, Your Honor, and people who have been falsely accused will die; you will have their blood on their hands, Judge Detonator. Will you be able to sleep at night knowing you signed the death warrants of innocent people? Your gavel ill be stained blood-red.Can you live with your conscience? Your Excellency, the cries of witchcraft are the same cries as a whore's vengeance fuelled by lust. People with names whiter than white within the community of Salem are having their good name soiled and blackened. Believe that if more people are accused by whore's like Abigail Williams and you continue to devour their lies, your soul will bec ome blackened and guilt-ridden. Judge Detonator, permit me to proceed, ninety-one people have signed a testament saying that Elizabeth, Martha, and Rebecca are good respected Christian women who loud never compact with Lucifer.Should ninety-one people lie? Think not. You cannot ignore the people of Salem any longer. You cannot ignore their good opinion or soon there will be no-one left in Salem who you think is somehow is working for the devil. The people of Salem must have known this woman all their lives; if they had compacted with Lucifer, would they have concealed it from their closest friends? If the devil had been working here, why has there not been any sign of the Devil before. You believe the lies Abigail Williams is feeding you with seemingly no care for the normal people f Salem.Is there another reason why you are not taking the testament of the god-fearing people of Salem? Seriously? I've noticed you sweat like a stallion whenever Abigail Williams is near. She is manipul ative , Judge Detonator and you must not fall in her trap. Will you take the words of one child, who is intoxicated by power, over the opinions of ninety-one upstanding members of the community? The ball is now in your court, Judge Detonator. The blood of these respected Christian women will be on your hands, Your Honor. Furthermore, after witnessing Mr..Jacobs' testimony in court, it became parent that this trial was never about witchcraft in the first place. This trial is a tale about greed and power, a soulless tale about people who want things that are not theirs. How can a man who can barely stand on his own two feet be accused of terrorizing Ruth Putnam? I would think that if he was under the impression of Lucifer, he would use the power to be able to stand up without any support. Mr.. Putnam is a parasite; sucking the blood out of innocent people for his own fat belly. Rut's accusations must be dealt with separately and with great care, Your Honor.Giles Corey swears to a depo sition that Putnam forced Ruth to cry witchcraft in an attempt for more land. Corey had been in court more than twenty times, winning every case, Your Honor. Surely, you can emphasize and draw the conclusion that Corey is reliable and trustworthy and that his deposition must be considered with great thoughts and wisdom. Plead with you to look at the evidence again. If you want the blood of Mr.. Jacobs on your hands, you should listen to the lies that Ruth Putnam is feeding you instigated by her father, the very greedy Mr.. Putnam.How could you not believe the words of John Proctor? Why the man with the rest name in Salem throw away his good name after claiming to be an adulterer? It is in my good opinion that Abigail Williams seeks vengeance on John Proctor for taking her innocence. Elizabeth lied to protect her husband, just like any women would lie to protect her family life, children and husband. Even someone like Goody Proctor, who has never told a lie before. This is a natural lie to tell. I beg of you, your Honor, to reconsider your decision on sending Elizabeth to the jailhouse. You must ensure that this trial is fair.Telling Proctor and Abigail to stand with their backs facing Elizabeth was not a air way to question her. You are a noble judge. We saw John Proctor break down in court and this is not the behavior of a man who is trying to deceive or undermine the court or the trial. Your Excellency, Proctor is a well-respected farmer and his wife has no mark upon her name. They are good souls who don't deserve to be hanged due to the lies of Abigail Williams and the girls. Abigail is hell-bent on seeking vengeance on Proctor. Abigail is comparable to Lucifer. She pulled the wool over your eyes , the girls and even me at the beginning.But I saw this presence and soon will you. She has deceived most people in the village including you. Can see she has played you like a violin and Your Honor , it seems you cannot hear enough of this wretched symphony. Beg o f you, see through the evil surroundings of Abigail Williams. F you kill these innocent souls, your hands will be stained blood-red. The blood of the innocent people you have killed. Your gavel , the paper you sign , the table and your soul will be stained with blood. In addition, the women we have already convicted of witchcraft are of the lowest status in Salem: a lunatic and a beggar.As the local beggar, there is not only one person in Salem who Goody Osborne has not annoyed with her requests for bread and cider. I can imagine there are a lot of people happy to see her locked up. But, consider Your Honor, does being poor equate to being a witch? Surely Lucifer would find it too easy to win the soul of a beggar! If Lucifer had taken Goody Osborne soul, why is she still poor? She is not such a fool to part with her soul for anything less than abundant money. Sarah Good, the local lunatic is in the same position- surely you see this? The local people are afraid of her trance mumblin gs and behavior.It is easy to cry witch on someone who is not in sound enough mind to defend herself. Judge Detonator, I humbly ask you to think more on these two individuals, there really is no sufficient evidence to send them to the jailhouse as they are just poor unfortunate souls. Finally, Sir, it's in my good Opinion that the accused are good people with pure souls. They are innocent and they have been caught up in a web of lies, Judge Detonator. You know as well as do that Abigail Williams and Thomas Putnam are not reliable enough to cause the deaths of innocent people.

Chemistry- Pennium Lab Report Essays

Chemistry- Pennium Lab Report Essays Chemistry- Pennium Lab Report Paper Chemistry- Pennium Lab Report Paper The relative abundance of the pre 1 982 pennies was 50 percent, and the relative abundance of the post 1982 pennies was 50 percent. The atomic mass of Pentium that was calculated using these isotopes was 2. 795 grams. A possible source of error could have been that the scales may have not given the correct mass due to various possible technological issues. This would have affected the accuracy of the data, as well as the calculated atomic mass. The initial hypothesis as supported because the atomic mass, 2. 795 grams, is in fact the average of the average mass of the pre 1 982 pennies (3. 090 grams) and the post 1982 pennies (2. 501 grams). This relates to what we learned in class about how the atomic masses of elements are calculated: by multiplying the relative abundance of the isotope to the mass of the isotope, then add all these values up. In this lab, the pre 1982 pennies were one isotope of Pentium, and the post 1982 pennies were another isotope of Pentium. The mass of the pre 1982 pennies as different from that of the post 1982 pennies because after 1982, pennies were made with more zinc instead of copper, and zinc has a lower density than copper. This would have caused the post 1982 pennies to be lighter than the pre 1982 pennies. Additional Research: From 1793-1837, the penny was made of pure copper. Then, a combination of copper, zinc, and nickel was used to manufacture pennies (95 percent copper, 5 percent zinc and in). From 1857 onwards, the penny was made of 88 percent copper, and 12 percent nickel. This gave it a whitish color rather than a bronze color. However, the penny reappeared with its bronze color with the 95 percent copper, 5 percent tin and zinc combination. In 1962, zinc was removed from the penny, and it was made of 95 percent copper and 5 percent zinc. In 1 982, the composition of the penny was changed to 97. 5 percent zinc and 2. 5 percent copper. This happened because it cost more than one cent to make a penny after the price of copper rose. Zinc was cheaper than copper, so the United States made the penny mostly out of zinc to save money.

buy custom Concerns of Cyberculture Identity essay

buy custom Concerns of Cyberculture Identity essay Having recognized the important role that is played by personal identity in it has become a core area of study in the emerging field of cyberculture theory (Dery, 1996). As Dertouzos (1997) postulates, theoretical studies seek to explain how communities interacting in the networked cyberspaces and sustained by the ever progressive modern technology behave in instances where personal identity is required and when it is not required. The same becomes relevant in determining cybercultures impact on the political, sociological, philosophical and psychological dimensions of human interactions (Dery, 1996). Key theorists in this area have included Donna Haraway, Manuel De Landa, Sadie Plant, Kevin Kelly, Wolfgang Schirmacher, Bruce Sterling, Jean Baudrillard, Hendrik Speck, Pierre Levy, Charles D. Laughlin, Victor J.Vitanza and Gregory Ulmer among others (Dery, 1996). Most of these theorists works concentrate on such themes as Futurism (Techno-utopianism), Feminist cyberculture theory, Postmodernism and the internet, Technological Determinism and Social Constructionism perspectives (Dery, 1996). Theoretically, cyberculture has resulted from information exchange, retrieval and storage enabled by networking computers via the World Wide Web (Jordan 2001). It is thus rightly referred to by many theoretical conceptions as an information culture. The future is seen to be ushering in the new revolution of mankind, the information age ion the continued process of evolution (Jordan 2001) also noted by Aronowitz, Martinsons and Menser (1995). The most important resource is soon going to be information and not industries as it has been, agricultural production as it ones was etc (Jordan 2001). The Wall Street trading concepts have today exemplified when information becomes valuable and resourceful. That is the promise carried by the theory of information age. As Jordan (2001) notes, in cyberculture, the importance of information is not lost, and the question is how the availability and easy transmission of that information is going to affect the society. This is especially important to consider when the people transmitting and receiving that information are unidentifiable or to use Kevin Kellys terms, are obsolete in personal identity statuses as quoted in (Dodge Kitchin, 2000).

How to Pass the ACT Expert Guide

How to Pass the ACT Expert Guide SAT / ACT Prep Online Guides and Tips There’s so much info out there about doing well on the ACT - a lot of it is really helpful when it comes to preparing for the test! But this onslaught of information can get pretty overwhelming, especially when you just want a simple answer to a simple question: how do you pass the ACT? What Does It Mean to â€Å"Pass† the ACT? On this test, there’s only a range of possible scores - what constitutes an excellent, poor, or average score will depend heavily on your frame of reference. Ultimately, what defines a passing ACT score is thatit’s high enough to get you into the colleges you’re applying to. This obviously varies widely by student. Your ACT score doesn’t have to be perfect for you to â€Å"pass† (although it never, ever hurts to bring up your score) - it just has to be good enough. Now, this gets a bit complicated because your ACT score is not the only part of your college applications. If your ACT score is particularly low, however, college admissions officers may have higher expectations for other parts of your app (e.g. GPA, extracurriculars). If your score is low enough, your application may get tossed out even if the rest of your app is strong. For the sake of this post, then, I’m going to define a â€Å"passing† ACT score as one that won’t get your application tossed out. Ideally, however, your ACT score will be one that helps (instead of hurts) your college applications. Keep reading to learn more about how to figure out these score benchmarks for yourself. How to Set an ACT Goal Score Before you learnhow to pass the ACT, you have to figure out what passing means for you. This requiresa bit of legwork: namely, researching what ACT scores are correlated with acceptance at the schools you’re interested in. Here’s how you do it: Make a Preliminary List of Schools This doesn’t have to be a final, polished list, but 8-10 schools you’re interested in is a good place to start. Try to select mostly â€Å"target† schools - colleges where you think you’d have a fairly good chance of getting in. You can include 2-3 â€Å"safety† schools and 2-3 â€Å"reach† schools as well, as long as you maintain balance here. Too many safety schools and you might set a target score that’s too low. Too many reach schools and you might set a target score that’s unreasonably, and discouragingly, high. The first time you do this, you may not have a good idea of what schools you’d identify as reach, target, and safety. That’s ok! In fact, it’s kind of the point of this exercise. You can repeat it as many times as necessary throughout the college process, adjusting your list of schools as you go. Look Up Each School’s ACT Info Start by Googling â€Å"PrepScholar [name of school] ACT score.† The first non-ad link that comes up should be the one you want - see below for an example. The first search result here is the one you want. The page will have the average ACT score and the 25th/75th percentile scores for students accepted to that particular school. Take down these numbers for each school. 25th percentile score = 25% of students at the school have an ACT score at or below that number 75th percentile score = 75% of students at the school have an ACT score at or below that number Students with 75th percentile scores or above for a particular school usually have a good shot at getting in, barring any weaknesses or issues with other parts of their application. Students with 25th percentile scores or below usually have other strong application components (e.g. high GPA, great essays) to boost their chances. Set Your Benchmark â€Å"Passing† Score This step is perhaps a bit more subjective, so I’ll be as transparent here as possible. If you want to come to a passing ACT score, you’ll want to look at a school’s 25th percentile ACT scores. This is far from a safe bet, however - your chances of getting in will heavily depend on the strength of the rest of your application if your ACT score is at or around the 25th percentile. If your GPA is lower than average for a particular school, for example, your ACT score would have to be higher in order to make up for it. I think that the best target (read: ideal) ACT score lies at a school’s 75th percentile score. The 75th percentile is a sweet spot because you’d be more competitive (in terms of ACT scores) than  ¾ of students who are accepted to the school. If your typical ACT score is higher than the 75th percentile score, you might want to consider looking at more competitive schools - you want to aim as high as you reasonably can here (more competitive schools often mean better reputations, which tend to lead to better outcomes). Here’s how to set both ideal and â€Å"passing† ACT score benchmarks for yourself: Take the averages of the scores you collected for each school. First the average of the 25th percentile scores, then the average of the 75th percentile scores. The 25th percentile average is your â€Å"passing† goal score - the minimum you should be aiming for. The 75th percentile score is your target score - the score that has a great chance of getting you accepted to the colleges on your list. What If You’re Worried About Reaching Your Target Score, or Even Your Passing Score? Perhaps these scores you’ve calculated seem higher than you would have expected. If your passing score in particular seems intimidatingly high, there are a few things to keep in mind: Remember that your target score (75th percentile average) is an ideal goal. It’s supposed to be higher than what you’re scoring now (or maybe even what you think you can score). If the 25th percentile benchmark seems too high, consider re-evaluating your list of schools. You might want to look at colleges that are slightly less competitive. Conversely, if you’re already at or above that 75th percentile mark, consider looking at more competitive colleges. Strategies for Passing the ACT I’m going to split this section up into two parts meant for two different types of students: low-scorers and high-scorers. Here, I’m defining score parameters by the national performance standards: high scorers are at about 24 and above (75th percentile nationally), whereas low scorers are at about 16 and below (25th percentile nationally). If your performance is closer to the average (20), check out both sections and follow steps that you find most useful. Your best plan from here will depend on both where you are and where you want to be. How to Pass the ACT: Guidance for Low Scorers One problem that a lot of low-scorers have is that they’re unsure of how to focus their time and energy when studying. Understanding your weaknesses is the first and most important step to tackling ACT prep. The biggest issue for low scorers is often significant gaps in content knowledge, so identifying and filling these gaps is typically a priority for ACT prep. Other mistakes may be due to: Running out of time Misunderstanding the question Running out of time Careless errors So how do you go about identifying where your issues are before taking steps to improve on them? First, you’ll have to invest some time in some serious self-analysis involving a baseline score. You can’t focus on improving before figuring out where you need to improve. Here are best practices for getting a solid baseline and gaining info on your weaknesses: Take a full, timed, diagnostic practice test Take note of which questions you got incorrect Tally the reasons for each incorrect question: Content Gap: Did you not have the information you needed to answer correctly? Timing Issue: Would you have gotten the question correct if you hadn’t run out of time? Question Misunderstanding: Would you have gotten the question correct if the question had been more clear? Careless Error: Would you have gotten the question correct if you had spent an extra couple of seconds checking your work? If you find that content knowledge is your biggest problem, you’ll want to turn to your class notes, textbooks, and ACT prep books for review - not just ACT practice materials. We also have a bunch of ACT content guides to get you started: Ultimate ACT English Study Guide Ultimate ACT Science Study Guide Ultimate ACT Math Study Guide Complete Guide to ACT Writing Once you’ve conquered major content problems, you can hone in on specific content areas and work on careless errors and timing issues. You’ll find tips for addressing those problems in the next section. How to Pass the ACT: Guidance for High Scorers If you’re a relatively high scorer, you probably have a general idea of where your major strengths and weaknesses are on the ACT. You’re likely pretty strong on content overall, unlike the typical low scorer. High scorers usually lose points due to three issues: Carelessness: loss of focus leading to silly mistakes Timing problems: you simply run out of time to give each question its due Content gaps: small areas of knowledge that you haven’t mastered 100% If you want to get close to that ideal score, you’ll want to attack each of these potential issues. I’ll address each of these problems in this section, but you may want to check out our detailed guide for high scorers for more info. Carelessness It’s pretty easy to identify a question you’ve missed due to carelessness. You get that horrible feeling when you recognize that you would have gotten the question right, if only you’d paid a tiny bit more attention. Careless mistakes often occur when students aren’t actively reading. Start focusing your attention with these tips: Double-read each question and underline important words. Take notes on passages. In the math section, mark up diagrams with important info and write out your arithmetic. Double- check your answer before marking it down. Timing Issues Running out of time at the end of sections? First, spend less time on easy questions - just keep an eye out for those careless errors. Next, skip tough questions and come back to them later. This doesn’t mean you shouldn’t guess if you’re out of time (there’s no guessing penalty, so you should definitely guess). If you’ve still got plenty of time to work through the section, though, mark the problem question and come back to it later. Timing issues can stress out pretty much everyone, but with practice, you can learn to overcome them. Filling in Content Gaps Your first task here is identifying which questions you get wrong in your practice, and more importantly, why you get them wrong. This means going over all your mistakes after each practice session. Keep a careful tally of each content area every time you identify an error (hint: most content errors happen on the math section). Use your class notes, textbooks, or reliable ACT prep book to review this content. Come back and do more practice problems in this area until you’re confident in your understanding. What You Must Remember About How to Pass the ACT There might not be an official ACT passing score, but that somehow seems to make things more complicated. What you might consider passing will depend on the sorts of schools you hope to get into, but I hope you think more in terms of target or goal scores than just â€Å"good enough† scores. If you’re worried that your ACT scores aren’t up to par, don’t worry just yet - there are tons of things you can do to bring them up, no matter where you might be on the percentile charts. What matters most when setting a passing score are the goals you set for yourself. What’s Next? There are a lot of helpful materials available if you’re worried about â€Å"passing† the ACT.

Competitive Strategies Research Paper Example | Topics and Well Written Essays - 1000 words

Competitive Strategies - Research Paper Example This paper concentrates on competition between two rival companies, Coca Cola Company and PepsiCo, and the strategies they employ to make sales and increase profits in the soft drink industry. How PepsiCo corporate cultures differ from Coca Cola Company The strategies that the two companies use differ in their method of advertising, search for new markets whether globally or nationally, and uncovering market niche that they can they control easily. Pepsi controls the youth markets for soft drinks in America while Coca Cola concentrates in the others. Coca Cola went global and seized a new market, which Pepsi has been unable to penetrate. These companies also employ the method of cutting costs. Coca Cola uses a lot of money for advertisements compared to Pepsi, which uses relatively a low amount. This helps Pepsi cut costs even though it makes huge profits. These companies also use anti-competitive practices such as exclusive dealing. Pepsi and Coca Cola companies exclusively supply c ertain businesses enterprises with their products and ensure that the rival’s products are not sold (Capparell, 2007). Advertising is crucial as it helps draw attention to a product and enables in the recognition of a company. Coca Cola and Pepsi companies have engaged in many advertisements across the globe in a bid to promote sales of their products (Moses & Vest, 2010). To a certain extent, Coca Cola and Pepsi have produced advertisements with common themes emphasizing on having fun but have continued on different courses over the years (Foster, 2008). Coca Cola leans towards an emotional position of branding while Pepsi maintains an energetic, music-oriented and humorous strategy. Pepsi’s advertisement strategy appeals to a younger audience since they largely use celebrity endorsements thus helping Coca Cola focus on the older generation. Coca Cola’s advertisement strategy ensures that the theme focuses on the global aspect, therefore, attracting a wider arr ay of consumers. Pepsi started its global campaign in 2012, therefore, has not been able to target consumers globally (Emerald Group, 2006). In order to keep pace with each other, both companies have employed different tactics that have seen an increase in sales and profit margin. In order to induce demand for its soft drinks, the Pepsi Company utilizes a pull strategy, employed in its distribution channels. However, this strategy concentrates on the younger generation, which is the main target market for Pepsi. As compared to Coca Cola, Pepsi’ product positioning controls the youth market in terms of demographics. The two companies constantly have to come up with new marketing ideas that help them capture their target markets (Johnson, 2013). How competition has benefited the rival company Due to the intense competition between these companies, innovations have been introduced to give each company an advantage over the other. The two companies have introduced a wide range of new products, which are sold at premium prices. PepsiCo has introduced alternative beverages such as Gatorade and Aquafina, which are sold at high prices. The brands bring high profits to the company due to customer’s brand loyalty that has been built over the years. Coca Cola also introduced numerous alternative beverages brands and they have made profits competing with PepsiCo, as some consumers prefer their products to the other companies (Thompson, 2012). Competition between PepsiCo and Coca

Renewable Energy - Essay Example le published in How to Power the World, â€Å"the waste products of nuclear power contain â€Å"high levels of radioactive (materials which) is very dangerous. It lasts for tens of thousands of years before decaying to safe levels. It is highly radioactive and is probably the biggest hurdle we face if nuclear power is going to be taken seriously† (How to Power the World 2010). Nuclear energy has great potentials to augment sources of energy in the future. It use, however, should be further evaluated in terms its long term effect to the environment and the risks it poses to the existence of mankind. Another article entitled An Ocean Breeze: Mapping Brazil’s Offshore Wind Power Potential written by Riebeek (2009) proffered his experience on â€Å"assessing the feasibility of an offshore wind farm southeast of Brazil† (Riebeek, 2009, par. 1). His project entailed measuring wind speeds using Nasa’s QuikScat. The limitations of using this approach coupled with other challenges including the number of turbines that must be built in their projected location showed that although this source of renewable energy is viable in Brazil, there are other factors that need to be seriously evaluated prior to its implementation. The high investment cost proved to be a barrier for implementation as private or public organizations need to examine if the returns on investment would justify the initial funds needed to support and sustain this energy source. among all of its potential applications, hydrogens only waste or byproduct is H 2 O pure water, hydrogen fueled combustion engines actually clean the air they pass through (Alternative Energy, n.d., par. 3) it is costly to produce, dangerous to store, difficult to transport, tricky to distribute and its volumetric energy intensity is much lower than that of other liquid fuels like ethanol or gasoline. Safety would be another problem and it would be an enormous job, and would take many years, to accomplish the logistics and

Financial viability within a health care organization Essay

Financial viability within a health care organization - Essay Example On the other hand, finance deals with concepts, methods, and principles of managing the relevant accounting data for the purposes of attaining certain goals for the business or any given organization (Wiedemann, 2009). Finance involves an aspect of management precisely because it anchors on decision making using available information. Generally, the process of financial management involves the determination of a range of factors that determine the performance of a business or organization. Alternative definitions have explained the difference between accounting and finance by terming finance as a decision science, which relies on the rational methods and means supplied by accounting to arrive at informed decisions, which appertain to the performance of an organization (Wiedemann, 2009). Some theorists have extended this definition to infer that accounting is subordinate to financial management to the extent that it supplies the raw data on which it builds its synthesis. However, experts emphasize on the complementary relationship between the two fields with clear demarcations of areas of specialization. Finance is largely used within the ranks of management although it applies to all levels that have particular interest in financial predictions, budgeting, risk analyses, performance projections, and many other attributes the determine the daily running of businesses and non-profit organizations. The multiple natures of application of the theories and principles of fin ance lend itself to various interpretations in connection with nature of processes and type of organization. The accounting processes and financial management in a healthcare sector are special and different from the usual processes as they relate to normal businesses. According to some financial analysts, the major distinguishing aspect of healthcare finance and accounting is that sources of income are not directly connected to the beneficiaries of

Project management Research Paper Example | Topics and Well Written Essays - 1250 words - 2

Project management - Research Paper Example cusses the history of project management, its significance in the contemporary age, some of the obstacles that project managers commonly face in their work and the functions of project management. â€Å"Project management is the science (and art) of organizing the components of a project, whether the project is development of a new product, the launch of a new service, a marketing campaign, or a wedding† (MPUG, 2011). Project management, as the name implies, includes everything that is required to manage a project. A project is a one time endeavor. It is unique. Some people confuse the definition of project with that of process. The former is unique and non-repetitive whereas the latter is repetitive in nature. According to Lewis (2002), projects have been managed for thousands of years, yet it has been identified as an entirely separate disciple all over the world in the last ten years. This tells how short the history of project management is. The claim of Lewis (2002) has been reinforced with the support of Azzopardi (2009), though Azzopardi (2009) dates the development of project management of tools in organizations to the mid of 1950s. ‘Project Management’ is an important topic because all organisations, large and small, are involved in implementing new undertakings as diverse as the development of a new product or service, or a public relations campaign. To keep ahead of their competitors, every organisation is faced with development of complex services and processes. These need cross-functional expertise in a given organisation. (Modesto and Tichapondwa, 2009, p. 15). Every project is different and has its own specifications. The risks and opportunities associated with every project are unique. Two projects may be of entirely same nature with the same project parties, location, and time, yet the two may call for entirely different patterns of management. This can be attributed to the difference of various internal and external factors arising in the

The History of Native of Americans Research Paper

The History of Native of Americans - Research Paper Example They form several tribes and there are around 335 federally recognized tribes in the United States alone, excluding Alaska. The 2011 United States census bureau shows that there are approximately 5.2 million Native Americans. The Native Americans have a rich and diverse culture which date back to their ancestors and their culture has contributed greatly to their wider recognition (Barnes 76). Modern day Native Americans and where they live in the United States Most modern day indigenous Americans live in North America in the United States and Canada. The modernized ones live in large cities with other races and some in the reserves where they farm and hunt. Those who live in reserves have some Indian laws that govern them. For instance, some have tax laws that differ greatly to states taxi laws. In some tribes, alcohol and gambling are illegal and are severely punishable. Even though the Native Americans of the United States are subject to their tribal laws and elect tribal elders wh o lead them, they are still the citizens of the United States and they obey and follow the federal laws of the United States (Bright 31). They also vote just like the other races and can join and serve in the military or police. Studies show that most Native Americans in the United States are still trying to cope with adjustment of civilization and belong to all economical classes from the most primitive to the most sophisticated. Majority of Native Americans have adapted modernity and face the risk of becoming endangered. This is because the children of the Native Americans fail to learn their native language, leading to death of the languages. According to the 2008 census 70 percent of Native Americans live in the urban areas and like to be identified by their tribes such as Cherokee, Beothukm, Inuit, Hawaiian, and Cree Indian among others. Many of them like speaking their languages or maintain their practices even if they are thousands of miles away from their homelands (Carney 2 8). The largest Native American tribe according to the 2006 census was the Cherokee with a population of 331,000, followed by Navajo with 230,000. The economy of the Natives ranges from good to worst, a few have made it affluence particularly those who have utilized natural resources in their lands and those who trade oil and run casinos. The rest of thousands of Native Americans are still in poverty and survive on hunting and small-scale farming (Bright 77). They live at starvation levels and the government of the United States provides aid to support them. The 2006 census shows that the median annual income of a Native American’s household by was $33,132. The revenues of their businesses in 2002 amounted up to $26.4 billion. The percentage of Native Americans living in poverty was 22, while that of the ones with no health insurance was 29 percent. In terms of education, some are highly educated. The 2006 Census shows that the percentage of Native Americans with a high schoo l diploma is 77% while 14 % have a bachelors degree or higher. Majority of these have relocated to the cities where they work to earn their living (Pritzker 67). Some have completely assimilated and even intermarried with the white race and other races. However, some live in complete isolation from other races. The relocation programs run by various organizations and the federal government have considered the Native Americans for jobs in the cities (Carney 47). The Colonial Era The colonization of America by Europeans was encountered by resistance and rebellion from the indigenous people. The Native Americans did not want their lands to be taken or get subjected to alien

Was Andrew Jackson Democratic Essay Example for Free

Was Andrew Jackson Democratic Essay Throughout time changes have been made to our country’s government in hopes of improving it, and reducing the flaws it has. Andrew Jackson made changes to our country in hopes of increasing its chances of longevity; however his methods in doing so are to this day very controversial. While Andrew Jackson was known as â€Å"the people’s president† his methods for improving America were quite ambiguous, and the concept of Jacksonian democracy is highly criticized. Andrew Jackson made contributions to our country while holding office; however his tactics were anything but democratic. Growing up on the frontier Andrew Jackson was the first president to not grow up wealthy, later in his life it proved to be useful in trying to appeal to voters, which proved to be successful. Yet in the race for presidency, even though he had won the votes, he did not win the election; John Quincy Adams, with the help of Jackson’s enemy Henry Clay, became president. In the next election to come Andrew Jackson had proved to be more successful, in acquiring the role of the president, both Jackson, and his ally Martin Van Buren, created a political organization, in what is now known as the democratic party. All seemed well, and politically Andrew Jackson had not made a mistake yet, However although he was known as a man of the people, Jackson believed in and promoted slavery. Jackson owned a plantation named The Hermitage. The Hermitage was a huge self-sufficient plantation that raised cotton and relied on the labor of African American men, women, and children. On his plantation there was rigorous labor that his slaves preformed daily. Due to the hard work of Jackson’s slaves, he continued to profit, and allowed him to acquire more land, thus he bought more men women and children to work his land, and help continue prosperity the Jackson family. Moreover, Andrew Jackson was skilled in military tactics; however he used his knowledge to take millions of acres of land from Native Americans. In 1814 he commanded the U.S. military forces that defeated a faction of the Creek nation. In their defeat, the Creeks lost 22 million acres of land in southern Georgia and central Alabama. As president, he continued to try and acquire more Indian land for white settlers who wanted to grow cotton, much like him. In 1830 Jackson signed the Indian Removal Act which allowed the government to move the Indians out of cotton rich land, and into Indian  reservations out west. This travel took a toll on many of the tribes, and the journey the Indians took came to be known as the â€Å"Trail of Tears†. In addition, there was the Supreme Court case of Cherokee Nation v. Georgia, where the Supreme Court ruled in favor of the Cherokee Nation. This ruling of the Supreme Court did not stop Jackson and his followers from driving the Cherokees off of their land, which people viewed unconstitional from Jackson’s part. Furthermore, Jackson was also known for many â€Å"injustices† while holding office, and criticized for expanding the power of the presidency. He was also known for rewarding his political supporters with government jobs. When it was brought up to his attention, he responded by claiming he was replacing aristocrats with the common man. Jackson stated To the victor go the spoils, and thus created the spoils system in government. Lastly, Jackson was portrayed as a sort of tyrant by his enemies, they even named him â€Å"King Andrew the First,† this was due to Jackson having the most vetoes out of all the presidents that came before him. With so many vetoes on Jackson’s part sometimes it seemed difficult to get anything done. His denial of a bill to re-charter a Second Bank of the United States was a significant event in Jackson’s term. To conclude, While Andrew Jackson did have a few positive outcomes for our country while he was president, it doesn’t ensure that he was completely democratic. In fact, his actions were quite opposite of democratic views. He did not respect Native Americans or African Americans. He used His military background to assist in the removal of Indians from their land, so that white Americans can raise cotton, while the Indians were moved westward so that they would not make obstacles for white colonists who wanted to expand. And he contributed in the creation of the spoils system. Andrew Jackson did strengthen the two-party system, he was not completely democratic.

This problem is related with getting information about visiting places and eating, as in this city, Emily has faced problem in accessing expert knowledge and using Google maps mainly because of unavailability no local leaflets, paid advertising links, etc. As such, the design report reflects the PACT analysis and includes observations supporting this analysis. Further, it also includes secondary research as well as reflects feedback for initial design. All in all, an interactive system design for this design problem will be helpful in giving effective and relevant knowledge to the visitors about visiting and eating. PACT analysis is defined as a user requirement document that is used for a more detailed design brief. This analysis is a way of reflecting about people, activities, content and lastly technology (PACT Analysis). Each and every element of this analysis would be quite helpful in developing an effective interactive system that supports the users in accessing the local map. People reflect cognitive with physical characteristics, language, culture, etc. and other aspects. Activities indicate about actions and tasks including activities that support the new design. The third aspect is the context to use focuses on information about environment with acceptability of new design in relation to social, legal and ecological. Lastly, technology focuses on current technology and future technology to asses the problem in existing technology and type of technology, which will be used to solve out this technical issue. In relation to the given design problem, PACT analysis is conducted to make the information accessible to visitors. People: In this activity, people involved are senior team members, IT engineers having a good knowledge about hardware and software technical areas, graphic and interactive design experts and research team. There is a special requirement for IT experts and research team as both affect the designing of the interactive system. The special requirement for Information Technology (IT) expert is due to the reason that they have possessed a practical technical knowledge about software and hardware. Research team members have great domains in programming, visual design and cognitive psychology. The age range for each and every person involved is different. For the senior team members, the age range is in between 35-50 years. They can play a decisive role in building an interactive environment through solving behavioural issues. All in all, senior members can build up a good coordination among the members to effectively communicate ideas. Further, team members between 20 and 30 include those, who have innovative ideas and support in completing the tasks. IT engineer, graphic engineers and research team members are between the age range 30 and 45. In developing an interactive system, they can support in the designing of prototype and non-functioning prototype interface. In the current scenario, language is a great issue as visitors have faced problems in assessing the local knowledge due to unfamiliar language. Activities: To design an interactive system, the users have to perform activities that furnish long and in-depth information to the visitors. Additionally, they have to design a system in such an effective way that not only supports the visitors in searching local knowledge about the worth visiting and eating through providing database, but also works as a tool that freely intercommunicates knowledge to the visitors. Those activities must possess special characteristics like system should be easy to use, fast, and efficient. The new design will support in completing the activities like designing of interface, which is self teaching and also assists in gaining access to relevant and worthwhile information. Context to use: The features of the current context are that the presentation of local knowledge was not good in this city. Besides that, the system is not quite fast and effective with which it could be easy to assess the information. The environment would be stressful as the existing system was not responsive to the needs of the users. The new system needs to be used quickly through providing training in relation to the technical issues and ways to implement and maintain. In the designing of an interactive system, it is a must to focus on the needs of society, so that the society can be able to accept this system. For the new design, ecological and social acceptability affects the system at a great extent as both play a vital role in making the system user centric. Current technology: Technology is one of the determinative areas of concern as it directly affects the system design. Currently, notice and language are used as technology to respond to the needs of the users in a fast and efficient way without focusing on its ease to use. All in all, the current technology to serve local knowledge is mainly based on the systems functionality instead of visitors needs. This is a major problem in the current technology. Besides that, the current technology does not reflect the local attraction in the station and thus; visitors have faced a great problem in knowing places for visiting and eating without any guide. Future Technology: To solve this problem, the technology that could be used must focus on the users needs and also possess the characteristics of easy to use. Furthermore, books and signs are an effective technology that could be applied to cope with this problem as this will be helpful for the users in accessing knowledge about the local attractions of the particular city. Hardware helps the visitors that are looking for new attractions through informing and assisting in searching worth visiting places, whereas; software helps in making the database of local attractions in a city and also maintaining the speed and efficiency. This technology might provide opportunities like easy to access information within few minutes. Besides that, this technology might also give information about local attractions on mobile phone at low costs. For offering more functionality in the new system, new technology like books and signs might give an opportunity to attract number of visitors and also mee t visitors needs by assisting in keeping away the problems related to access expert knowledge. Observations supporting the PACT analysis Based on the above discussion about PACT analysis, it is inferred that this analysis is a quite effective tool with which it could be easy to assess information in a more detailed form. Besides that, it is also reflected that PACT analysis not only focuses on the specific requirements, but also indicates key point that are quite essential for evaluation. For instance: information about people helps in knowing people involved in the tasks. Furthermore, I have learned that for designing an interactive system, this analysis is highly effective as this helps in realizing the current situation and also reflects the areas for improvement, so that the new system can easily cope with the perceived problem. All in all, it is realized that PACT analysis is an effective tool to understand the users needs and amend the system according to the users acceptability. From the observations supporting the PACT analysis, it is learned that in this rapidly changing technological world, it is a must for an interactive system design that each and every aspect including people, activities, context and technology is properly assessed. With this, it would be easy to design a system that gives local knowledge of what is worth eating and visiting in a particular state. In addition to this, these observations will support in assessing the required changes that make the user interface effective in respect to functionality and users needs. Overall, PACT analysis is a tool for cooperative research, which acts as computer-aid-engineering for sharing and developing design model automatically. In the same concern, it is also observed that PACT analysis for an interactive system should also consider the communication as this meets out the issues like speed and bandwidth. In addition to this, observations will greatly assist the web designers in knowing about the users context, goals and tasks that directly lead in supporting the PACT analysis. With the observations, it could also be easy to assess whether the design prototype assists the goals and tasks in an effective way (Sharp, Rogers and Preece 2008). All the given observations in relation to the support of the PACT analysis were quite useful as they helped in getting relevant information about activities, context and technology. In response to the observations, the design visualization will add such a technology that gives a full and clear picture of area for improvement and also focuses on usability that makes visualisation easy to understand. Besides that, I will add more pictures, maps, signs, etc. as well as apply design strategies related to user interface. To make design visualisation effective, we will add all types of analyses including users, requirements and tasks. Thus, it is inferred that PACT analysis for an interactive system must be human centric, so that the required information can be easily extracted by the users. Secondary research Secondary research is one of the effective researches with which it could be easy to find out the solutions in context to the chosen scenario. This is because potential solutions linking with such issues are already reflected by other researchers. In helping the design of an interactive system, secondary research is quit useful as this research gives detailed information about the tourism and environment in context to the ecological, cultural, economic and language issues. Besides that, in design/visualization, secondary research will help in finding out the user requirements that are essential to design interactive system. In this context, Jones and Greene (2000) state that in the interactive system design, it is a must to foster creative perception, users and use context. The interesting idea that helps in developing the design is We view good system design as a three-legged stool. The legs are: 1) Understanding of technology, 2) Understanding of the users and the context in which the system will be used, and 3) A creative insight (Jones and Greene 2000). This means that a good system design is highly based on the proper knowledge and understanding of the users and technology as this is the only means to provide local attraction information to the visitors. It is also assessed from secondary research that for an effective design/visualisation to provide a guide to the tourists, it is a must to focus on the computing technologies with wireless infrastructure in order to provide the required information about the worth visiting sites. In support to this, Cheverst et.al state that The system combines mobile computing technologies with a wireless infrastructure to present the city visitors with the information tailored to both their personal and environmental contexts (Cheverst et.al). With this, it is analysed that for developing an interactive system, technology should be related with the users requirements. To make the design effective, another interesting idea proposed by Wober (2003) is that the designing of interactive system has to be supported with a marketing decision support system to assess the information about the prevailing users demand and current technology (Wober 2003). . Based on the above reflected potential solutions for the selected scenario, it is inferred that secondary research is good means as this research refers to the information that has been collected and properly analyzed by other researchers in context to the same issue. Feedback on the Design Visualisation In respect to the design visualisation, most of the users have reflected that this is a good system through which users can easily access the information of local destinations as this not only provides them with the database, but also helps them communicate in relation to various issues related to environment. This system would help in getting information about the worth visiting and eating sites, so that visitors can spend their time and money in an efficient way. As per their feedback, they would expect to see mobile networking with which they can access information on global maps on their mobiles at a lower cost. After looking at visualisation, most of them have the same question that whether this system is easy to use and will be helpful in fulfilling their needs. In response to the feedback, I would like to focus on all key dimensions such as technology, context and users. In addition to this, I would like to change the technology such as books, pens, notices, etc. to make the s ystem easy to use for the visitor. Besides that, I will implement mobile networking to change the design as most of the potential users highly require this technology in the interactive system.

The Characters Metamorphoses In Shakespeare’s Tempest-Universe Essays

The Characters' Metamorphoses In Shakespeare’s Tempest-Universe In the play The Tempest, Shakespeare provides a unique and alternate universe for his characters to function in on the magical island. In this universe there are both native characters: Prospero, Miranda, Ariel, and Caliban, who have lived on the island previously, and external world characters, namely: Alonso, Ferdinand, Antonio, Sebastian, Stephano, Trinculo, and Gonzalo, who have been forced upon the island. While the different characters' histories cross paths in the past, the clear and present division between the two groups' immediate situation represents the division in their differing kind of spiritual journey. That is, while the natives seek rejuvenation from isolation outward, the shipwrecked characters seek rejuvenation from the outside world inward, on an island of solitude. As David Bevington notes in the introduction to the Bantam edition of the text: Shakespeare creates in The Tempest an idealized world of imagination, a place of magical rejuvenation like the forests of A Midsummer Night's Dream and As You Like It. Yet the journey is no escape from reality, for the island shows men what they are and what they ought to be. Even its location juxtaposes "real" world with idealized landscape: like Plato's New Atlantis or Thomas More's Utopia, Shakespeare's island is to be found both somewhere and nowhere. (xvii) In this Tempest-universe Prospero rules as a kind of artist-king, creator, and magician. Invested with these qualities he represents the God-figure of the universe, effecting change in others, while consistently demonstrating God-like qualities in himself: the ability to perform miracles, grace, and forgiveness.

Abortion: A Woman Has the Right to Choose Essay -- Argumentative Essay,

The right to choose what happens to YOU is an American right that every person should be allotted. Though the First Amendment clearly states that all Americans have the right to freedom of speech, the topic of abortions continues to be challenged. Abortions poses moral and ethically challenges that many Americans ponder over. The major two sides involved in this is heated issue is â€Å"Pro-Life† vs. â€Å"Pro-Choice†, pro-life being against and pro-choice supporting abortions. This research paper will examine the many different court cases affecting abortions and the two different arguments What is an Abortion? â€Å"An abortion is the termination of a pregnancy by the removal or expulsion of a fetus or embryo from the uterus before it is viable†, (Grimes, 2007). An abortion can happen for two different ways, either because of problems during pregnancy or by inducing one because of choice. Abortions usually refer to the induced terminations while terminations related to medical issues are commonly called miscarriages. Obviously the controversy comes into play when dealing with the induced terminations. †Induced abortion has a long history and has been facilitated by various methods including herbal abortifacients, the use of sharpened tools, physical trauma, and other traditional methods. Contemporary medicine utilizes medications and surgical procedures to induce abortion. The legality, prevalence, cultural status, and religious status of abortion vary substantially around the world. In many parts of the world there is prominent and divisive public controversy over the ethical and legal issues of abortion.

Motivation in the Play Essay

Villains and why they do their villainy is always justified or explained in any literary work. Even those childhood fairy tales with the villain’s formulaic and predictable evil deeds will always do things that have a purpose or will do those things because they were compelled to do it caused by a negative feeling: jealousy, revenge, envy, greed, a childhood without someone to love them or support them, etc. William Shakespeare’s plays are not an exemption to this case as he even creates characters that are capable of not only of evil; they embody evil in their totality as a person—if you may call them that. An example of this would be Iago, touted as the most villainous of all villains in the literary world because of the simple reason that he was guiltless, conscienceless and definitely purposeless in his strategic deeds that destroyed Othello and the people close to the tragic hero. This analysis will focus on this villain and scrutinize his character, villainy and most of all, his purpose (or the lack thereof) on why he did the things he has done that aimlessly ended to other people’s lives. In fact, there is already an answer to this query for Iago is just plain evil, nothing less and definitely more. His motivation lies in the fact that he wants to end other people’s happiness and takes simple delight in causing other people pain and grief which makes him not just a villain but a very mysterious and most terrifying one. In Othello, the Moor of Venice, a man’s capacity to do evil is magnified as Iago is overcome with rage as Othello gives a position to another less qualified man that was originally intended for Iago. Iago takes this in deep and plots against Othello, a Moor in Venice that holds such high position, influential power and great riches. Iago uses jealousy to destroy Othello and the people around him by making it appear that Othello’s loyal wife, Desdemona, is having an affair with another man. In rage, Othello kills his own wife and when he realizes that it was all Iago’s evil plan, he kills himself out of grief and guilt. Iago confesses to no one and does not explain his actions; instead, he keeps mum about what he has done and the purpose in them. Thus, as the play concludes, it is only the audience who are witnesses to Iago’s malice and the extent of his wickedness—but there is a possibility that Iago also leads the audience into believing that they know the entire truth when in fact, he has been dishonest the whole time to everyone—even that of the audience. Iago acts as the villain in the play even if he was not really the one who did the bad deeds. He is the sole villain because he was the master plotter in the whole thing that even innocent people like Roderigo and Emilia were implicated as bad people when they were not wholly that capable of evil. Roderigo and Emilia were simply pawns to his plans and he used them and easily discarded them. In the book of Dobbs & Wells entitled The Oxford Companion to Shakespeare, they sum up the villainy of Iago (and pretty much, the entire play) in a few words: He skilfully convinces Othello that his wife Desdemona has been adulterous with Cassio. He wounds Cassio, murders Roderigo, whom he has involved in his plots, and also kills his own wife Emilia. (211) The extent of Iago’s villainy does not merely end in his acts and plans but in an entirely different context and case because his villainy was unjustified and unexplainable. He did not have a purpose and an aim in ruining Othello’s life and soul. For even if it seems that Iago was motivated by the anger he felt over Othello’s passing over the position that was rightfully his to another man that was very much unqualified (according to Iago that is), it still seems not enough motive. In the first part of the play (act I, scene i), Iago insists that he does hate Othello and does a lengthy monologue on why he hates the Moor. However, it can be later learned that maybe Iago was not really motivated by that trivial act done by Othello since Iago has never really revealed the real reason on why he hates Othello. This is because in the same act, he declares that he will never say what he feels and thinks because it is dangerous and it is laughable: For when my outward action doth demonstrate / The native act and figure of my heart In compliment extern, ’tis not long after / But I will wear my heart upon my sleeve For daws to peck at. I am not what I am. (Shakespeare 1. 1. 63-7) His supposed reason on hating Othello may not be his true reason for the vendetta he so chillingly instills on the Moor because Iago will never disclose his real reasons. Thus, even though Iago was transparent with his feelings and thoughts to the audience and some characters like Roderigo and Emilia, he actually lied to everyone since he could never â€Å"wear his heart† on his sleeve. Moreover, even if the rage he felt over Othello’s actions propelled him to do/plan such things, it was not enough to completely destroy the life of one man and the lives around that man. To think that Iago even killed his own wife with his own hands—without a second thought on doing it or a guilt overcoming afterwards. As what Dobbs & Wells wrote, Iago was a â€Å"motiveless evil† and that lack of motivation in him makes him a superior proponent of evil (211). In conclusion, Iago is most villainous not just because of the things he has done but also because of the lack of motivation in them, the absence of purpose, the incapacity to be guilty over the success of his evil plans and most of all, the mockery he throws to the characters and the audience at the end of the play with his silence. This silence is eerie as it has a purpose—to make everyone shiver at what other havoc and damnation he could have done with that evil mind of his.

Isolation of Casein From Milk

In this experiment, casein was isolated from milk by means of isoelectric precipitation. A percent yield of 5% was obtained by the group.IntroductionMilk is an opaque white or bluish-white liquid secreted by the mammary glands of female mammals, serving for the nourishment of their young. This liquid, as secreted by cows, goats or certain other animals are used by humans as food and as a source of dairy products such as cheese and butter. Milk composition differs widely among species. Factors causing these variances include: the type of protein; the proportion of protein, fat, and sugar; the levels of various vitamins and minerals; and the size of the butterfat globules, and the strength of the curd. On average, cow milk contains 3.4% protein, 3.6% fat, and 4.6% lactose, 0.7% minerals and supplies 66 kcal of energy per 100 grams. Bovine milk normally contains 30-35 grams of protein per liter. Of which, 80% is arranged in casein micelles.Figure 1. Model of Casein SupramoleculeContaini ng a fairly high number of proline residues, which do not interact and no disulfide bridges, casein has, as a result, relatively minimal tertiary structure. It is comparatively hydrophobic, resulting to its poor solubility in water. Showing only limited resemblance with surfactant-type micellae in a sense that the hydrophilic parts reside at the surface and are spherical, casein is found in milk as a suspension of particles called â€Å"casein micelles.† On the other hand, the interior of a casein micelle is highly hydrated. The caseins in the micelles are held together by calcium ions and hydrophobic interactions.Casein’s isolelectric point is 4.6. It has a negative. The isoelectric point (pI) is the pH of a solution at which the net primary charge of a protein becomes zero. At a solution pH that is above the pI the surface of the protein is predominantly negatively charged and therefore like-charged molecules will exhibit repulsive forces. Likewise, at a solution pH that is below the pI, the surface of the protein is predominantly positively charged and repulsion between proteins occurs. However, at the pI the negative and positive charges cancel, repulsive electrostatic forces are reduced and the attraction forces predominate. The  attraction forces will cause aggregation and precipitation. The pI of most proteins is in the pH range of 4-6.Mineral acids, such as hydrochloric and sulfuric acid are used as precipitants. The greatest disadvantage to isoelectric point precipitation is the irreversible denaturation caused by the mineral acids. For this reason isoelectric point precipitation is most often used to precipitate contaminant proteins, rather than the target protein. The precipitation of casein during cheesemaking, or during production of sodium caseinate, is an isoelectric precipitation.tive charge in milk since milk’s pH is 6.6.1 Results and DiscssionCasein was isolated from milk by means of isoelectric precipitation. A percent yield of % was obtained by the group. Table 1 presents the data and results obtained from the experiment which includes: (1) the weight of powdered milk, (2) the initial pH, (3) the final pH, (4) the volume of the acetic acid used, (5) the weight of casein and (6) the percent yield. In order to compute for the percent yield, the weight of the isolated casein was divided by the weight of the powdered milk, and then multiplied by 100%.Table 1. Data and results of the experiment: Isolation of Casein from Milk. Before autoclaving, the isolate was a white-yellowish solid with smooth texture. After autoclaving, it turned into a brown solution with black precipitate. The filtrate was a yellowish solution. The general principle behind this experiment is that when casein is at its isoelectric point, it is generally at the pH where it is least soluble. As a result, casein precipitates at this pH. To explain further, casein is present in milk as calcium salt, calcium caseinate. It is a mixtur e of alpha, beta and kappa caseins to form a cluster called micelle. These micelles were responsible for the white opaque appearance of milk.The casein, as proteins, is made up of many hundreds of individual amino acids, each of which may have a positive or a negative charge, depending on the pH of the [milk] system. At some pH value, all the positive charges and all the negative charges on the [casein] protein will be in balance, so that the net charge on the protein will be zero. That pH value is known as the isoelectric point (IEP) of the protein and is generally the pH at which the protein is least soluble. For casein, the IEP is approximately 4.6 and it is the pH value at which acid casein is precipitated. In milk, which has a pH of about 6.6, the casein micelles have a net negative charge and are quite stable.During the addition of acid to milk, the negative charges on the outer surface of the micelle are neutralized (the phosphate groups are protonated), and the neutral prote in precipitates. The same principle applies when milk is fermented to curd. The lactic acid bacillus produces lactic acid as the major metabolic end-product of carbohydrate [lactose in milk] fermentation. The lactic acid production lowers the pH of milk to the IEP of casein. At this pH, casein precipitates.2. Experimental5g of powdered non-fat dry milk was dissolved in 20 mL warm distilled water in a 100-mL beaker. The solution was heated on a hot plate to 55 °C. The beaker was then removed from the hot plate. The initial pH of the milk solution was noted. A solution of 10% acetic acid was then added dropwise whole while being stirred by a stirring rod. The acid solution was continuously added until the pH reached 4.6. The volume of the acetic acid used was noted. The solution was left standing until a large amorphous mass was formed.The isolated casein was dried between filter papers. The casein was weighed and the percent yield was determined. The isolated casein was then divide d into two portions. One portion was used for acid/base hydrolysis. The other portion was stored in the refrigerator (to be characterized later using various chemical tests).
