Disciplining Style Differences of Divorced Parents Essay

Introduction Families come in all shapes and sizes. Some families have two parents in the home, others are ran by single parents, while others have stepmothers and stepfathers with children having biological and half-siblings. These dynamics are intriguing and often I have wondered how the parents in such families may differ in their parenting styles based on the relationship of the Mother and Father. In the traditional family, the Mother and Father are generally married and reside in the same household raising the children they have created together, while other families of divorced parents may have joint custody of their children and live in separate residences. I am curious to know how these parents operate, specifically in the area of discipline. Child Behavior tends to be greatly effected by a change in the family structure, such as divorce. Not only do children behave poorly in school after a divorce, but also there are studies that show High School drop out rates are significantly higher i n a single parent household than a home with dual parenting. This study will serve three purposes. The first is to describe the disciplinary practices of a divorced parents, studying the most common techniques used by the average divorced parent. Next, this study will explain the effectiveness of these techniques, examining the result of child behavior in each of the examples. Finally, this study will outline the most effective discipline techniques for divorced parents to avoid the behavioral problems that a divorce can bring upon a child. The most effective disciplinary techniques for divorced parents is to work together throughout the disciplinary practices, remaining consistent amongst both parents and delivering on punishments for incorrect behaviors. This ensures well-behaved children and increases the likelihood of educational success of their children. Problem Statement Children of divorced parents suffer with behavioral issues much more often than children from traditional family dynamics consisting of a two-parent households. Theses issues include small consequences such as bad behavior in the classroom and can be even more sever such as increased likelihood of high school dropouts. In fact, in a study reviewed by Green, K., of a group of students who came from a divorced family, only â€Å"about 60 percent received high†¨school diplomas† (Green, 2009). This is compared to 78.4% of students from a traditional household of two parents. Changes in parenting should be able to reduce these risks and there is no better way to change parenting styles other than researching the different styles of parenting and examining the most effective techniques. Divorced parents often lack a partnership and consistency that a dual parent household has, and so, in order to prevent negative consequences from poor child behavior, divorced parents need to work together, remain consistent, and hold their children accountable for their actions. The question this study hopes to answer is, how are divorced parents’ disciplinary actions different from traditional families, and what can they do to ensure their child’s success? Rationale Child behavior is so important since it is often said that past behavior is a good indicator of future behavior. â€Å"The empirical finding that childhood problem behavior is predictive of adult problem behavior has been documented in several longitudinal samples, regardless of time, place, sample characteristics, or specific measures of outcome† (Ensminger, 2006, p194). Children tend to behave more poorly when they are raised in a home of a divorced parent, so it is important to understand the approaches taken by these parents and assess their effectiveness in order to explain the best disciplinary techniques so that this behavior can be corrected early enough to eliminate the risks of behavioral issues in children. This study is meant to be more than just a description of parenting styles, but, also serve as a guide for divorced parents as well. Research Objectives This study will serve three purposes. The first will be to identify the most common disciplinary approaches amongst divorced parents and traditional families. Amongst these approaches, we will then determine the most effective of these approaches, which is the second objective. Finally, We will fulfill the third purpose, which is to understand the complications that divorce brings upon a parent in disciplining, and suggest helpful tips from the most effective parenting styles researched. When all is said and done, we would like to help single parents who are raising their children after a divorce understand the importance of good discipline practices, most commonly found in traditional families and avoiding any potential negative impacts of child behavior. Hypothesis My guess is that most divorced parents do not take the time to research the most effective parenting techniques, especially in the area of discipline. This can help them assess their current strategies and open their eyes to all new approaches with the most successful outcomes. I would guesstimate that most single parents lack discipline due to the fear of loosing the popularity contest they’re in with the ex-spouse and their children. This is unfortunate because they are actually doing more harm than good. A child that does not have discipline in the home can result in terrible consequences, both for the child as well for the society in which this child will live in, since links to criminality have already been established with child behavior and lack of discipline. I would predict that if divorced parents were to use effective discipline, such as, working together, remaining consistent and keeping their children accountable for their actions, then they would raise better-behaved children and increase the chance of a successful life for their children, much like their traditional family counterpart. Definition of Terms This paper will have several terms that will have several terms that will be defined in this portion and will be implemented throughout the study. The first term I wish to define is the term â€Å"traditional family†. A traditional family will be defined by a household in which the children live with both their mother and father and both are married. The next term defined is a divorced family, or a family in which the children’s parents have divorced and no longer live together. The term â€Å"children† will describe adolescents under 18 years of age. Another term is discipline, which we will define as any action taken by a parent to correct the bad behavior of their children. Finally, we will define Behavior as the actions and/or attitudes displayed by a child. Summary It is imperative that children be disciplined for displaying poor behavior. This can prevent such outcomes as high school dropouts and criminal activities, which is often the result of bad childhood behavior. Divorced families often lack discipline in the household, due to the absence of partnership amongst divorced parents and consistency in parenting, so, in order to prevent negative consequences of child behavior issues, divorced parents need to work together, remain consistent, and hold their children accountable for their actions. I predict that traditional families have a lot of differences in their disciplinary practices such as teamwork, consistency and accountability that is deficient in a divorced family, where the parents are separated in different residences. Much can be gained about researching effective disciplinary techniques, especially amongst divorced parents, well-disciplined children can increase the livelihood of their adult life and ensure a more promising futur e, which is everything a parent hopes for their children.

American Ethnic Literature

The word ‘ethnic’ denotes or derives from distinctive ways of living created by a group of people. Hence, American ethnic literature must be influenced by the ethnic or cultural ties of an ethnic American author, and must reveal to some extent the distinctive ways of living practiced by the ethnic group that the author represents. Biographical criticism entails a deeper comprehension of an author’s work by knowing the essential details of his or her life.Because writers are real people, the literature that they write generally contains reflections of themselves, the kinds of people they encounter in their lives, and the circumstances that they face. Not all people in the United States belong to the white European race. The Indians were settled on our land before the European whites came along to change the history of the land for ever. Africans were initially brought by the European whites to work as slaves on plantations. The Hispanics and the Asians also entered the land as immigrants.Still, the dominant community in the United States, in terms of population, is that of the European whites. Theirs is the predominant culture in America, and their literature is known as mainstream American literature. At the same time, the Native Americans maintain some of their ancient rites, in spite of America’s predominant culture of the European whites. The African Africans continue to be influenced by the music that their ancestors made on the ships that brought slaves to America (McBride, 2007). The Hispanic Americans and the Asian Americans also maintain aspects of their culture through their distinctive languages and foods.Unsurprisingly, these cultural differences must reveal themselves in American ethnic literature as compared to mainstream American literature. American Ethnic Literature 2 All of the different groups representing the Americans today are maintaining their ethnic differences, even if many of their members feel that they are o ne with the mainstream culture. As a matter of fact, it is but natural for the various ethnicities representing America in our time to be maintaining cultural differences, while trying to fit into the mainstream culture.As mentioned previously, the culture of different ethnic groups must reveal itself in the writings of ethnic American writers. When an American ethnic author does not reveal his or her distinctive culture in literature, however, it is reasonable to claim that the person’s writings represent mainstream American literature. Zane, for example, is an African American author of erotic fiction who is writing mainstream American literature. Although the author belongs to an American ethnic group, her writings do not reflect her ethnicity.She sometimes uses middle-class African American characters in her novels, but she also employs white American characters. Even so, an American writer of European descent may also be expected to do the same. Besides, Zane does not ma ke references in her books to her own race as opposed to the Americans of European descent, and neither does she complain about the problems that the Africans have gone through in America. Rather, the characters in Zane’s erotic novels could be people belonging to any number of races (Zane, 2001; Zane, 2005).One of Zane’s novels, Afterburn, is about a chiropractor in Washington D. C. who visits his local bank because he is interested in one of the employees of the bank. He believes that she is too beautiful to be a single woman, which is the reason why he has never asked her out. When American Ethnic Literature 3 he does, however, he finds out that she has a history of disastrous relationships. He, too, has a broken heart. And so, the two of them finally get together (Zane, 2005). While forming their bond, the man and the woman have to meet a variety of characters who add spice to their relationship.The woman has a fickle minded mother, the man has got playboys as budd ies, and then there are lovers from the past that keep trying to disrupt the new relationship. Nevertheless, Zane manages to turn the relationship into a tie of deep love and longing (Zane, 2005). Most importantly, she creates a story that could happen in anybody’s life. Because Zane is an American, her literature must be considered mainstream American literature. She is an African American, but her literature cannot be considered American ethnic literature seeing that it does not solely reflect the culture and values of the African Americans.Instead, Zane is one of those ethnic American writers who appear to have totally blended into the mainstream American culture. On a similar note, Jamaica Kincaid (1990) in her novel, Lucy, presents a nineteen year old young woman by the name of Lucy Josephine Potter who is trying to forget her roots in the West Indies. In the process, no doubt, the girl is trying to blend into the mainstream American culture. Kincaid is an American ethni c writer who was born in the West Indies (Benson & Hagseth, 2001). A biographical critic might assert that Lucy, the girl who came to North America as a nanny, is a reflection of the author.Regardless, Kincaid’s novel about Lucy may be considered American ethnic literature only because it contains glimpses of the author’s ethnicity. Lucy hated her old home, a British colony; and yet memories of her mother continue to haunt her, taking her back to West Indies. Her mother acts as a symbol for Lucy’s motherland. The American Ethnic Literature 4 girl feels emotionally unattached to her mother, and finds a better motherly model in the United States by the name of Mariah, who acts as a symbol for the new land the girl has come to occupy.Mariah replaces Lucy’s mother with respect to the kinds of feelings people are taught by nature or nurture to feel for their mothers. Moreover, Kincaid’s novel establishes a clear difference between Lucy’s mother a nd the character of Mariah. For example, Lucy’s mother was emotionally dependent on her daughter, to the point of becoming an emotional pain. The mother was also neglectful of the needs of her young daughter. Mariah, on the contrary, treats Lucy as a grownup. She exposes Lucy to the museums of America, and gives her presents.She also looks out for the well-being of the young Lucy during the time that she is adjusting to the new environment (Kincaid). Lucy feels far from her roots in West Indies. She would not read her mother’s letters that arrive in the mail. She wants to avoid the emotional pain that her mother brought into her life, by being oppressively reliant on her daughter. Furthermore, Lucy is trying to leave colonialism behind. She had shown rebellion in West Indies toward the oppressive invasion of the British. She had refused to sing in her school choir, â€Å"Rule, Britannia!† Just as her mother keeps on being brought to mind, colonialism surfaces in young Lucy’s flashbacks of West Indies. She wants to get away from it all. In America and on her own, the young girl would like to be an individualist, able to make her own decisions, and forgetting all that was painful and negative about the past (Kincaid). Because the focus of Kincaid’s book is the girl’s desire to blend into the mainstream American culture while forgetting the past, the novel may also be termed mainstream American American Ethnic Literature 5 literature.Given that it describes the author’s ethnicity thoroughly, however, it must be considered in part American ethnic literature. Amy Tan’s (1989) The Joy Luck Club is similarly part mainstream and part ethnic American literature. Containing sixteen stories that revolve around conflicts between old-fashioned mothers who are Chinese immigrants, and modern daughters who have been raised in the United States, the novel describes the mainstream American culture in addition to the Chines e culture. Tan is an Asian American author, and therefore her writing should have been ethnic American in its entirety.However, her writing reveals that an Asian American author feels like an American before she can relate to the Asian experience. Additionally, although the writer tries to bridge the gap between the two cultures that she is supposed to represent by having her characters travel to China, it is a fact that the American experience cannot be discounted by any means. The only ethnic American authors who write American ethnic literature must be ones who reflect solely on their ethnicity in their works, showing utter disregard for the mainstream American culture.The following passage describes some of these authors: During the years preceding the Civil War, America’s ethnic and racial minorities began to publish novels, poems, histories, and autobiographies that explored what it meant to be an outsider in a predominantly white, Anglo-Saxon, Protestant society. The r esult was a unique body of ethnic writing chronicling the distinctive experience and changing self-image of ethnic Americans. One of the earliest forms of African American literature was the slave narrative, graphic American Ethnic Literature 6first-person accounts of life in bondage, written by former slaves, including William Wells Brown, Frederick Douglass, and Josiah Henson†¦ These volumes not only awoke readers to the hardships and cruelties of life under slavery, they also described the ingenious strategies that fugitive slaves used to escape from bondage. William and Ellen Craft, for example, disguised themselves as master and slave; Henry â€Å"Box† Brown had himself crated in a box and shipped north. †¦Native Americans, too, produced firsthand accounts of their lives. Among the mostnotable is the Life of Ma-Ka-Tai-Me-she-kia-Kiak or Black Hawk (1833), a classic spiritual and secular biography, in which the Sauk warrior explains why he resisted white efforts to seize Indian land in northwestern Illinois during the Black Hawk War (1832). William Apes, a Pequod, published one of the earliest histories from an Indian vantage point in 1836. John Rollin Ridge, a Cherokee journalist, published the first novel by an Indian in 1850, The Life and Adventures of Joaquin Murieta, which recounts the heroic adventures of a Robin Hood–like bandit in California who protects Mexican Americans from white exploitation. Much more than a simple adventure story, this novel is also a thinly veiled protest of the treatment of Native Americans by someone who had personally experienced the removal of the Cherokees from their tribal homelands in Georgia (â€Å"American Ethnic Literature,† 2007). Such is truly American ethnic literature. It focuses solely on the ethnicity of the author, while disregarding if not rejecting the mainstream culture.On the other hand, novels by ethnic American authors that reveal the differences between mainstream Americ an culture as opposed American Ethnic Literature 7 to the authors’ respective ethnicities are not true American ethnic literature. This is due to the fact that the authors as well as their characters have attempted to blend into the mainstream culture by getting rid of their ethnic identities to a large extent.

Article Rebuttal Essay Essay Topic: Art , African American Choose cite format: APA MLA Harvard Chicago ASA IEEE AMA Barack Obama (128) , rebuttal (10) For the past 17 months, shown on every television news channel across the United States. The case of George Zimmerman, and the shooting death of 17-year-old Trayvon Martin. Like every year, the media will take a case and publicly turn the story into a circus. The rebuttal article for this paper is a story written by Oliver Knox of Yahoo.com titled, â€Å"Obama: Trayvon Martin could have been me 35 years ago.† Further discussion will analyze the reliability, credibility, and validity of the data used by Oliver Knox, and identify any logical fallacies in the argument. The article is about President Barack Obama making his first public comments on the George Zimmerman acquittal. The president stated that many African Americans believe the outcome and aftermath of the trial would have been different if Trayvon Martin had been white. The president later stated that when he first heard about this story, his thoughts said this could have been his son (Obama, 2013). Then getting more personal by saying this could have been me 35 years ago (Obama, 2013). By using personal experiences, the president discussed his life as a young African American dealing with racism in the United States. I find that the reliability, credibility, and validity of this article and author Oliver Knox highly trusted, convincing, and believable. News articles written and posted by Yahoo.com reports a straightforward message to their audience. Reporting stories down the middle, never too left or right with the occasional bias author either for or against a particular topic. Keeping political views down to a minimal. This particular article matches other similar articles written on the same news story. Second, Oliver Knox wrote the story on the statements and words of the president as he addresses the American public. Third, the genuine author of this story is President Barack Obama himself, Oliver Knox just wrote his statement. The audience that the president focused on in his address is the African American people. Using his own personal experiences, the president can relate to the ongoing outrage of the African American  public. President Obama feels the pain and disappointments of the outcome of the case. Because of this story first came out 17 months ago, many logical fallacies surfaced about this case. First, the media leaned toward a killing of an innocent young 17-year-old boy, minding his own business. Then showing a photo of this boy at the age of 12. Then here comes George Zimmerman, looking for trouble and looking for a fight by picking on a young African American boy. Would the story stay the same if George Zimmerman was African American with the same outcome, the public will never know what happened that night. Meanwhile, the story set the tone for future stories about this case. Raising the question about race possess anything to do with the incident between George Zimmerman and Trayvon Martin. The logical fallacies of this article happened when President Obama expressed his concerns and personal experiences with the American people. This incident could easily be him 35 years ago as a young person dealing with racism in America. Concern that African Americans think that this case developed on race. A belief in the legal system would have a different outcome if Trayvon were white. Even after juror number B37 came out stating that race had no issue to the outcome of the case. Both the jury and legal experts stated that Zimmerman and Trayvon made poor judgment the night, which led to the death of Trayvon. Statements by the jury referring the only reason for Zimmerman’s acquittal because the way the â€Å"stand your ground† law is written. This article also provided some good highlighted points. The president encouraged his audience to support and encourage the young people of this country by helping them achieve and succeed in life. To be more influential and guide them on the right track. If the young people do not have the support from family, friends, neighbors, and the community, who will help them stay on the righteous path (Obama, 2013). This news article written by Oliver Knox and other journalists in this country, reporting the feelings and concerns addressed by this nation’s leader. Stating the issue of racism still lives in the lives of some American people. Relating to his own personal feelings on racism and demanding change to overcome these barriers. So the people, as a nation will never see another George Zimmerman and Trayvon Martin case again. References Knox, O. (2013). Obama: Trayvon Martin ‘could have been me 35 years ago’. Yahoo New.com.

Short Fiction Selections - Essay Example This quote captures the typical life of almost individual in this current society. This is because things have become tough, and life is rough and cruel on some people especially with regard to lack of income and poverty. Those who are fortunate to have money may also lack some vital elements of life such as joy. As a result, the harsh reality is that individuals in this society hardly achieve what they wish to have in life. In order to console themselves, most individuals use several activities and concepts that take them into the world of illusions in order to escape from these harsh realities. Several literary works indicate how different individuals in the society use imagine space to create illusions and pretend that they are in a world where they wish to be. In The Last Speaker of Language by Carol Anshaw and Pilgrim Life by Taylor Atrim, the characters love and a sense of belonging to forget their problems, albeit on a temporary basis. Similarly, in the short story Navigators by Mike Meginnis, the characters drown their problems using video games to avoid the realities that they have to face. Likewise, in other short stories such as Volcano by Lawrence Osborne, Diem Perdidi by Julie Otsuka, The Day of the Locust by Nathanael West and Culver City by Richrad Lauge, the characters employ several techniques to create illusion and experience the imaginary world. In today’s society, people use the imagine space to escape from their harsh reality. The authors through the short stories portray how characters use love and a sense of belonging to experience the imaginary world and escape everyday harsh realities. For example, in The Last Speaker of the Language, Darlyn comments,  Ã¢â‚¬Å"It’s just about—even for a day—being this purely happy.  Like, happy to be a carbon-based life form† (Anshaw 7). In another short story, Pilgrim Life, one quote that relates to this topic says, â€Å"Pilgrim Life† starts with that calmin g view, that apartment, my millionaire roommate, my wine magazine job. The rest of it I entirely made up (I swear) over a three-month stretch in the midst of the worst financial crisis I’ve ever lived through† (Atrim 67). These quotes clearly illustrate how the characters create their own imagination in order to avoid real world. For instance, Darlyn expresses how she values happiness, and acknowledge that it may be for a short time, but is so important. This happiness helps her to escape from the problems with her alcoholic mum as well as job related problems. Similarly, in Pilgrim Life quote, the character acknowledges that not all the good things that he mentions are real, which shows that he sometimes seek imaginary experiences in order to escape from the problems that he has with his-girlfriend among other problems. Dreams and illusions is another strategy used by the authors to demonstrate how the characters uses imagine space to forget their problems. For instanc e, in the short story Volcano by Lawrence Osborne, Martha dreams of things that she would wish for, for example, she thinks that she can change her dream, and thus, change her situate\ion of being with an older man. Perhaps this comes from the technology captured in the following section, â€Å"The dream technique includes a drug and goggles that emit infrared light during REM sleep to allow the dreamer to be present in the dream and remember it, even influence it: by touching a rough surface†(Osborne 10). Other instances of illusion include Diem Perdidi by Julie Otsuka with the most famous quote â€Å"she remembers she does not remember.† She is suffering from dymensia, however, she can remember some things from the past. The most interesting part is that what she

Economy recession - Assignment Example The former was achieved by formulating monetary policies which included lowered interest rates (as low as 0%), heavy purchase of Treasury bonds and mortgage securities and liquefaction of credit for financial markets and institutions. The deposit insurance limits for financial institutions were increased and comprehensive stress tests were conducted to ensure the stability of the existing institutions. TARP (Troubled Assets Relief Program) was launched in 2008 to navigate finances back into the banking institutions (Blinder and Zandi, 2010). These efforts ensured that the existing institutions were strengthened to face dire circumstances and that the financial system of the country was saved from its looming demise. Attempts were also directed towards the control of recession through policies. Several middle and lower class tax payers were granted with rebates, ARRA (American Recovery and Reinvestment Act) was passed and several small stimulus measures were inducted. The deteriorating condition of the housing sector was rescued by reducing mortgage rates, providing of legal and larger loans, granting tax credits for homebuyers and through the bail-out services of TARP. The auto industry was also saved largely by TARP funds which revived the three major auto companies of US and the world (Blinder and Zandi, 2010). Even though the federal budget was highly strained in process, a recovery in the economic downfall and a change of course towards economic growth was achieved. It took two administrations, the Federal Reserve and the Congress to pull US out of its deteriorating economic conditions (Blinder and Zandi, 2010). Their policies are highly criticized as these had exerted immense strain on the Federal Reserve and the US Budget. Nevertheless, it is highly possible that the US economy would have been largely demolished if such aggressive actions were not

CONTEMPORARY CASES IN PUBLIC POLICY - Essay Example One reason surrounding the democratic ability of basic income is, it would make available important prospects; to list but a few, the freedom not to acquire employment. Stakeholders tend to evade round the distinct implication, albeit I shall differ, it is vital to the democratizing possibility – provided the income can be pre-determined within most preferred level. Not even ideas of basic-income or capital funding utter anything regarding the level to be set. The level so proposed depends on the reasons behind this proposal. We shall assume that, for a basic-income to become significant for democratization, it ought to be adequate to make available what we call a humble but honest standard of living .This level is sufficient, as it allows individuals to have control over course of their lives. According to Ackerman et al. (2006, p 27), the disagreement among Ackerman, Alstott and Van Parijs in their essays is under the latter’s prevention on capitalization of basic-income into a units of payment. Van Parijs converges the differences between basic-income and capital grant, and explanation that disparity between them as collateral, for example; a mortgage on a house, and concentrate on prohibition against conversion of a basic income into a single lump sum. The question is whether this constitutes a significant limitation on individual freedom. As provided by Ackerman et al. (2006, p 16), Ackerman and Alstott argument is that, basic income is an obstacle to individual freedom. Young people find it hard to achieve their goal if they fail to choose to capitalize their basic-income at the same time as a capital grant. Ackerman and Alstott, consequently, see a basic- income as the constraint on change, they carve in to the Stakeholder Society, they are paying attention in opportunity and not outcome, and they present basic-income to mitigate failure, while as a stake is initiation path for success.† Nevertheless, this instigate

Great Pyramid of Khufu Personal Statement Example | Topics and Well Written Essays - 1000 words

Great Pyramid of Khufu - Personal Statement Example I hope to be an architect one day, and seeing these marvelous wonders first hand would be an experience like no other. I would be able to marvel at the complexity and genius that went into building them, and actually get to be there, an experience that could not be attained simply by reading a book or looking at a picture. I have estimated that the air fare for the trip will be around $2800.00 for round trip tickets; the hotel would cost around $500 dollars a night, for a total of 5 nights. I would also allow myself 100 dollars. The only other small cost would be the cost of admission to the pyramid. The Great Pyramid at Giza is one of the seven wonders of the ancient world. It is also the only of the seven that has survived the test of time and remains today ( http://ce.eng.usf.edu/pharos/wonders/pyramid.html). This not only shows the monument's unique look back into an ancient time, but also its uncanny ability to resist time, and to withstand each and every century as if it were nothing. This is a tribute to the hard work and time that went into building this great marvel of the world. The pyramid is "756 feet long on each side, 450 high and is composed of 2,300,000 blocks of stone, each averaging 2 1/2 tons in weight. Despite the makers' limited surveying tools no side is more than 8 inches different in length than another, and the whole structure is perfectly oriented to the points of the compass."( http://www.unmuseum.org/kpyramid.htm). These figures show how much work and care must have gone into the completion of this great work of art, and how advanced the methods of this structure must have been. It is because of how intricate and advanced this structure is, as well as its height and history, that I feel it is important to get to see as part of growing as an artist, architect, and person. Despite the enormous size and history of the project, how exactly that Great Pyramid was completed is a riddle that time may never answer for us. "Herodotus said that it would have taken "30 years and 100,000 slaves to have built it."(http://interoz.com/egypt/cheops.htm). However, exactly how long it took, and how many people it took is a question still debated by scholars and historians. However, many historians believe that Herodotus got many of his numbers wrong, and that it took less workers and less time that Herodotus recorded for us. It is not far fetched to think this, as by the time Herodotus visited the Great Pyramid, it was already 20 centuries old, and many of the information may have been lost of mixed up already (http://www.unmuseum.org/kpyramid.htm). The Great Pyramid of Khufu is the largest pyramid ever built, and, "it incorporates about 2.3 million stone blocks, weighing an average of 2.5 to 15 tons each. It is estimated that the workers would have had to set a block every two and a half minutes."( http://www.nationalgeographic.com/pyramids/khufu.html). The immensity and hard work that went into this monument are just two of the factors that make it resistant to time, and also make it an invaluable work of art to visit on my trip to Egypt. The precision and care that went into this work of art was also great. Perhaps to combat problems that had happened with other pyramids being built around this time, great care was given to the detail and measurements of the pyramid, which is an achievement in itself with the primitive tools the Egyptians would have had to

Provision of Customer Service within Intercontinental Hotels Group Case Study

Provision of Customer Service within Intercontinental Hotels Group - Case Study Example In accordance with Hoffman et al. (2008) customer services excellence can be achieved in modern organizations by focusing on specific sectors, such as: ‘competence, credibility, security, communication, responsiveness, accessibility and understanding’ (Hoffman et al. 2008, p.418). On the other hand, McNeill (1993) notes that customer services excellence means that ‘the organization is able to identify and fulfill the customer’s unique expectations’ (McNeill 1993, p.87). It is explained that the above target offers to the organization a competitive advantage towards its rivals who are able to offer to their customer only a series of standardized services. In the study of Christopher (2005) another approach is used for explaining the service excellence is used; in accordance with the above researcher the achievement of service excellence is depended on the ability of the organization involved to create ‘a market-driven logistics strategy’ ( Christopher 2005, p.65). Trying to explain the context of customer service excellence, Gallan (2008) supported that the specific term is used for referring to ‘service that meets or exceeds provider and customer expectations’ (Gallan 2008, p.30). It is made clear that customer services excellence can significantly help the development of organizational performance; however, the potential requirements of the specific initiative would be made clear ensuring that the risks for the organization involved are minimized. (Hoffman et al. 2008, p.418).  

The Survival Lottery By John Harris Essay Example | Topics and Well Written Essays - 1000 words

The Survival Lottery By John Harris - Essay Example Harris also assumes that no organs are available from the already dead so as to make the ethical choice sharp and clear.Lastly ,an obvious assumption is that the transplantation technology has achieved the status of ensuring complete success and that ill individual would live after the transplant. If organ donation was perfect and there was no difference between killing and letting die. Then we should adopt the Survival Lottery. The proposition by John Harris can be seen as an argument against Utilitarianism, although Harris himself often makes Utilitarian claims in his work. Let us adopt the famous illustration of Harris viz. that of three persons A,Y & Z.A is healthy and is potential target for organ transplant and Y & Z are both terminally ill and can be saved by organ(s) donation from A and subsequent 100% successfully done transplant(s). Simply speaking why not kill A to make Y and Z surviveOr should we allow Y and Z to perish.There are two arguments against letting Y and Z perish.One is the Utilitarian argument and the other the Fairness argument. The former says that we should do that which will have the best consequences and it is a better consequence if more people live. Therefore even if we intentionally kill a healthy person, doing so will save at least two unhealthy persons who otherwise would have died, more people will live thanif we refuse to kill the healthy person. So, we ought to intentionally kill a healthy person when doing so will save at least two unhealthy persons who would have died otherwise. The latter argument says that we shou ld not unfairly decide to kill anybody-it has to be on a fair basis.If we refuse to kill A then we have presumably decided to kill Y and Z and vice versa.Therefore an outright decision not to kill A ought not to be taken.Survival lottery proposition while agreeing with utilitarian argument that more lives are better than one suggests a "fair basis" to select the person to be killed from the available lot of healthy people viz.through random lottery. Arguments Against the Survival Lottery The Survival Lottery would undermine our security, something which all desire reasonably. The Survival Lottery fails to 'respect individuality' because it treats A, Y, and Z 'merely as interchangeable units.' The Survival Lottery involves 'playing God with men's lives.' The Survival Lottery involves us in killing, whereas refusing to practice the Survival Lottery only involves us in letting die. And killing is worse than letting die. The Survival Lottery is inconsistent with recognizing that every person has a fundamental right to self-defense. Harris's argument is based on the "maximizing lives" theory, as he believes there is value in numbers and that two lives are twice as valuable as one. As a consequentialist it does not matter to Harris how the

Thinking Like an Engineeering Essay Example for Free

Thinking Like an Engineeering Essay Summary of Michael Davis’ Thinking like an Engineer January 31, 2005 By: Harley Christensen  © 2005 www. harleyc. com Engineers have long considered themselves to be â€Å"professionals†, made possible by their near general adoption and use, formal affiliations aside, of a code of ethics. Varying code of ethics drafts are effective only through the actions of the engineers who abide by them. In his essay â€Å"Thinking like an Engineer†, Michael Davis gives examples of ethical challenges facing engineers , and takes direct aim at validating the use of ethical codes by the engineering profession. As a climactic opening, Davis relates the story of the Challenger space shuttle, highlighting not the disaster itself, but the dilemma of an engineer, Robert Lund, responsible for approving the launch. Sandwiched between his assumed application of a professional ethical code and the wishes of a capitalistic corporation, Lund decides (seemingly contrary to ethical code) to launch the shuttle. Given that the loss of life caused by this event is widely known, most readers would quickly conclude that Lund’s decision was absolutely incorrect, without first considering the true nature of the dilemma he faced. The Challenger disaster is hardly an effective example on which to base an evaluation of this type. Setting Lund aside for a time, Davis gives a simplistic description of the need for ethics in engineering, and which groups are benefited as such. He establishes that members of an â€Å"organized profession† have need for a formalized code to conglomerate them in the eyes of those they serve. Continuing, he gives excellent explanations of how engineering ethical codes provide â€Å"a guide to what engineers may reasonably expect of one another†. His core point, that ethical codes provide the â€Å"rules of the game† for engineers. With a professional code in place, it is up to the engineers to obey the code on an individual level. Davis states that engineers are not held to their ethical code by â€Å"anything so contingent as a promise, oath, or vow†, they participate in their profession under the statutes of the ethical code on their own accord. Drawing upon Lund’s decisions , Davis effectively demonstrates that in order for a code of ethics to be truly effective, it must be properly understood and applied. Otherwise, the benefits of being an â€Å"organized profession† will not be wholly realized. Davis shows that within the engineering profession, interpretation challenges arise from both an individual’s understanding of the ethical code wording, as well as the contexts in which they are to be applied. To drive his point, Davis gives a tiresome analysis of the meaning of the word â€Å"public†. Though relevant, his definitions do little to add weight to his arguments. In closing, Davis reiterates the responsibility that professional engineers have to correctly abide by their ethical code. They alone are responsible for incorporating the code into their work, and ensuring others do the same. With the help of ethical codes, engineers, as organized professionals, can more effectively serve their clients and benefit one another.

Emission Reduction Essay Example for Free

Emission Reduction Essay In every economic activity, both positive and negative implications compound such activities. The positive implications include employment increase, supply of goods and market, supply of public goods, environmental control above others. However, every economic activity is as well a compound of negative implications. These are called negative externalities. They include pollution, environmental degrading, increase in crime, and social evils above others. Emission reduction like any other negative externality calls for a very dynamic tools of control. Generally, the basic control of negative externalities by corporations in the economy is through the government taxation imposition. The government would impose a corporate tax levy which is substantially equivalent to the cost of the emission to the environment. Through such levy, the government uses passive methods of compensation to the community over such impacts of the emission. Through the tax levy, the cost of operation to the plant is increased. (Prencipe, Davies, Hoboday, 2003) Economically, taxation provides two cost related variables with which the plant should choose from. Firstly, through higher cost of production which may perhaps outweigh its level of market profits, the plant may be forced out in the market. This is because high tax levy is synonymous to an increase in the cost of production. With high cost of production the plant is at a competitive disadvantage in the highly competitive market. It may then opt to choose an alternative method of investment. (Prencipe, Davies, Hoboday, 2003) Elsewhere, such tax is a disincentive in the choice of production method. From the broad alternative of energy production e. g. use of electric turbines to generate power. Use of environmental friendly method would then call up such tax levied formerly. The basic purpose of higher taxes by the government towards negative externalities is to provide a disincentive in specific lines and methods of operation which are harmful to the environment. It is a tool for choosing alternative methods of production.

Memristor Spice Model For Designing Memristor Circuits Economics Essay

Memristor Spice Model For Designing Memristor Circuits Economics Essay Memristors are novel electronic devices, a device that can be used and give a great advantage in many applications such as memory, logic, neuromorphic systems and so on. A computer model of the memristor would be a useful tool to analysis circuit behavior to help in develops application of this memristor as passive circuit element via simulation. In this paper, we incorporate a memristor SPICE for designing memristor circuit which is more focusing on non-linear model and analog circuits. SPICE model would be appropriate way to describe real device operation. We incorporating the memristor with various window functions that have been proposed in non linear ion drift memristor devices. In investigating and characterizing the physical electronic and behavioral properties of memristor devices, the circuit analysis of the proposed memristor models are then been studied. The simulation output should have a current-voltage hysteresis curve, which looks like bow tie. The loops map the switch ing behavior of the device. Then, we come out with a simple analog circuit which in this case we construct a simple integrator op-amp and differentiator op-amp circuit and make comparison between memristor implemented circuit and normal circuit. The research verifies the proposed memristor model, the possibilities of implementing memristor model and the advantage implementing the memristor in analog circuit. Keywords memristor, SPICE model, non linear, window functions, analog circuit. Introduction Memristor is the contraction of memory resistor which is a passive device that provides a functional relation between charge and flux. It is a two-terminal circuit element in which the flux between the two terminals is a function of the amount of electric charge that has passed through the device [1]. A memristor is said to be charge-controlled if the relation between flux and charge is expressed as a function of electric charge and it is said to be flux-controlled if the relation between flux and charge is expressed as a function of the flux linkage [2]. In 1971, Leon Chua proposed that there should be a fourth fundamental passive circuit element to create a mathematical relationship between electric charge and magnetic flux which he called the memristor which is short for memory resistor [2]. The current is defined as the time derivative of the charge. The voltage is defined as the time derivative of the flux according the faraday law. A resistor is defined by the relationship between voltage and current dv=Rdi, the capacitor is defined by the relationship between charge and voltage dq=Cdv, the inductor is defined by the relationship between flux and current dà Ã¢â‚¬  =Ldi. The fourth fundamental circuit element completes the symmetry of the relation between charge and magnetic flux dà Ã¢â‚¬  =Mdq. Table 1 show the relationship between the fundamental circuit element. Basic two terminal devices Equation Relationship between fundamental circuit element Resistor,R dv=Rdi v and i Capacitor,C dq=Cdv v and q Inductor,L dà Ã¢â‚¬  =Ldi i and à Ã¢â‚¬   Memristor,M dà Ã¢â‚¬  =Mdq q and à Ã¢â‚¬   Table 1: The four fundamental element (resistor, capacitor, inductor and memristor). In 2008, Stanley Williams and his team at Hewlett Packard had succesfully fabricated the first memristor in physical device form which is a long wait from Leon Chua discovery in 1971 [3]. Memristance is a property of memristor. When the charge flows in one direction through a circuit, the resistances of the memristor increase. The resistance decreases when the charge flows in the opposite direction in the circuit. If the applied voltage is turned off, thus stopping the flow of charge and the memristor remembers the last resistance that it had [1]. In HP memristor model, to create a memristor, they used a very thin film of titanium dioxide (TiO2). The thin film is then sandwiched between the two platinum (Pt) contacts. One side of TiO2 is doped with oxygen vacancies denoted as TiO2-x which x is usually 0.05. The oxygen vacancies are positively charged ion and make it conductive, thus it behaves as a semiconductor. Another side of the TiO2 junction is undoped. The undoped region has insulating properties. The device established by HP is shown in Figure 1 [3]. Figure 1: Memristor model adapt from [3]. When a positive voltage is applied, the positively charged oxygen vacancies in the doped TiO2-x layer are repelled and moving them towards to the undoped TiO2 layer. When the boundary between the two materials moves, the percentage of the conducting TiO2-x layer is increase. Thus, the conductivity of the whole device increases. When a negative voltage is applied, the positively charged oxygen vacancies are attracted and pulling them out of TiO2 layer. This increases the amount of insulating TiO2, thus increasing the resistivity of the whole device. When the voltage is turned off, the oxygen vacancies do not move. The boundary between the two titanium dioxide layers is frozen. This is how the memristor remembers the voltage last applied [1]. Methodology Our aim in this research is to provide a simulation program adequately simulates and can be used as a circuit element in design work. To model the electrical characteristics of the memristor, SPICE would be appropriate way to describe real device operation [4]. Moreover, using the model as a sub-circuit can highly guarantee a reasonable high flexibility and scalability features [5]. We use LTSPICE to create a memristor model and design new symbol of the memristor circuit for the simulation because LTSPICE is much easier to handle compared to others. On the other hand, LTSPICE is a freeware and it will give a great advantage to the students in doing research for this newly devices. We use SPICE model that been adapt from [6] and we made some adjustment so we can use it for several window functions that has been proposed for non linear ion drift model. The SPICE model is created based on the mathematical model of the HP Labs memristor. After the memristor has been modeled, we first studied the difference between proposed memristor and then we will start design and implement the memristor with an analog circuit. We also investigate and made a comparison between the memristor circuit with analog circuit to see the difference and study the behavior of the circuits. Model Of The Memristor from HP Labs In the model of a memristor presented here, there is a thin semiconductor film that has two regions, one with a high concentration of dopant that behaves like a low resistance called RON and the other with a low dopant concentration with higher resistance called ROFF [3]. The film is sandwiched between two metal contacts as in figure 1. The total resistance of the memristor, RMEM, is a sum of the resistances of the doped and undoped regions, w is the width of the doped region and D is the total length of the TiO2 layer. ROFF and RON will be the limit values of the memristor resistance for w=0 and w=D. The ratio of the two resistances is usually given as 102 103. (1) (2) From the ohms law relation between the memristor voltages and current, we get (3) Then, we insert (1) into (3). The voltage v(t) across the device will move the boundary between the two regions causing the charged dopants to drift. So, there is a drift ion mobility  µv in the device. The change of the boundary is denoted as in (5). (4) (5) To get x(t), we then integrates the right side of equation (5) which then yields the following formula (6) By inserting equation (6) into equation (4) and since usually RON (7) Where  µv is the average drift velocity and has the units cm2/sV, D is the thickness of titanium-dioxide film ROFF and RON are on-state and off-state resistances and q(t) is the total charge passing through the memristor device. Non Linear Ion Drift Model Even a small voltage across the nanodevices will produce a large electric field [7]. This causing the ion boundary position will move in a decidedly non-linear. Nonlinear dopant drift adds nonlinear window function f(x) to the state equation. The window function decreases as the state variables drift speed approaches the boundaries until it reaches zero when reaching either boundaries [8]. The speeds of the movement of the boundary between the doped and undoped regions are depending on several factors. (8) Where  µv is the dopant mobility. The speed of the boundary between the doped and undoped regions decreases gradually to zero at the film edges [1]. We simulate the nonlinear ion drift memristor model with these window function to see the difference and the issue that been faced by them. Window Function Window function is a function of the state variable. Window function forces the bounds of the device and to add nonlinear behavior close to these bounds. In other words, it creates the boundary for the memristor. Any effective window function should therefore fulfill the following conditions [8]: Take into account the boundary conditions at the top and bottom electrodes of the device; Be capable of imposing nonlinear drift over the entire active core of the device; Provide linkage between the linear and nonlinear dopant drift models; Be scalable, meaning a range of fmax(x) can be obtained such that 0 à ¢Ã¢â‚¬ °Ã‚ ¤ fmax(x) à ¢Ã¢â‚¬ °Ã‚ ¤ 1; Utilize a built-in control parameter for adjusting the model. There are several window functions that have been proposed for non-linear model till date which are by Strukov, Joglekar and, Biolek, and Prodromakis. Strukov proposed the following window function [3]. (9) However, as we can see in the figure 2, this window function lacks of flexibility. Figure 2: Plot of Strukov window function. Another window function was proposed by Joglekar [4], which has a control parameter p which is a positive integer. The purpose of having a control parameter as an exponent is to incorporate scalability and flexibility in window function f(x) that describes the dopant kinetics. (10) Figure 3 displays a graphical representation of the window function described by Joglekar for various p parameter (p=1, 5 and 10). This control parameter controls the linearity of the model, where it becomes more linear as p increases. This window function ensures zero drift at the boundaries. From the plotted graph, we noticed that the maximum f(x) value is occurs at the center of the device and zero is obtained at two boundaries. However, a significant liability of this model lies in the fact that if w hits any of the boundaries (w = 0 or w = D) the state of the device cannot be further adjusted. This will be from now on termed as the terminal state problem. Figure 3: Plot of Joglekar window function for p=1, 5 and 10. Then, Biolek proposed another window function that allows the memristor to come back from the terminal state problem. (11) The reversed bias is now should move back the state variable after it reaches either boundary. This feature is described by a current dependent step function, stp(i), which is a part of a new window function f(x) that behaves differently in each voltage bias direction. (12) Figure 4: Plot of Biolek window function for p=1, 5 and 10. Figure 4 displays a graphical representation of the window function described by Biolek for various p parameter (p=1, 5 and 10). When x starts at 0, we noticed that the function equal to 1. As x increase approaching D, the function approaches 0. Once the current reverse the direction, the function immediately switch to 1. As x decrease back to 0, the function also decreases to 0. Biolek window function eliminates convergence issues at the devices boundaries. The last window function for non-linear model is proposed by Prodromakis [8]. (13) Figure 5 displays a graphical representation of the window function described by Prodromakis for various p parameter (p=1, 5 and 10). As we can see, it allows the window function to scale upwards which implies that fmax(x) can take any value within 0 Figure 5: Plot of Prodromakis window function for p=1, 5 and 10. SPICE Model of Memristor Figure 6: Stucture of the SPICE model from [6]. In the above circuit in figure 6, VMEM is the input voltage and Imem is modeled to be the current through the memristor. The flux is calculated by integrating the voltage VMEM and the charge is calculated by integrating the current IMEM. Figure 7: Resistive port of the memristor model. As we can see in figure 7, the circuit is actually referred to total resistor RMEM. RMEM (x) = ROFF -xà ¢Ã‹â€ Ã¢â‚¬  R where à ¢Ã‹â€ Ã¢â‚¬  R= ROFF-RON. ROFF is the resistor in series voltage source whose terminal voltage is controlled by the formula -xà ¢Ã‹â€ Ã¢â‚¬  R. Figure 8: Differential equation modeling of the memristor. Figure 8 shows the differential equation modeling of the memrsitor. It consist a part of the voltage controlled source xà ¢Ã‹â€ Ã¢â‚¬  R and the differential equation from equation (6) which serves as an integrator of the quantities on the right side of the state equation (6) which is to get the value of normalize x. EMEM is the voltage source whose terminal voltage is controlled according to the formula -xà ¢Ã‹â€ Ã¢â‚¬  R. GX is a current source whose current is controlled according to the equation IMEMf(V(x)) where V(x) is the voltage across the capacitor Cx and it models the normalized width x of the doped layer. F(V(x)) is the window function, k is  µvRON/D2 and x0 is the initial voltage of the capacitor.[6]. The relation between memristor current and voltage is modeled as on the basis of RMEM (x) = ROFF -xà ¢Ã‹â€ Ã¢â‚¬  R where à ¢Ã‹â€ Ã¢â‚¬  R= ROFF-RON. The voltage V(x) across the capacitor CX models the normalized width x of the doped layer. The initial state of x is modeled by the initial voltage of the capacitor. The flux is calculated by the time-integral of voltage, and the charge is calculated by the time-integral of current. Result and Discussion All models were simulated in LTSpice using SPICE model that was given in [6], we add new nonlinear window functions that was proposed by prodromakis and strukov to the model and compare all suggested window functions. memristor Figure 9: Memristor circuit. Figure 9 shows configuration of single memristor for measuring the behavior of memristor model in LTSPICE with a sine wave input voltage of 1.2V with 1Hz frequency. The values for the memristor parameters  µv, D, RON, ROFF and RINITIAL are 10-10cm2s-1V-1, 10 nm, 100ohm, 16kohm and 11Kohm. All model are using same window function parameter p=10. C:UsersFadzDesktopresultstrukovstrukov1.png Figure 10: Strukov memristor model voltage, IMEM, RMEM and normalized x. Figure 10 shows the simulation result of memristor SPICE model for Strukov window function of voltage, IMEM, RMEM and normalized x. As we can see, the current of the memristor, IMEM is varying up to approximately 100 µA for maximum of 1.2V voltage applied. The RMEM for this model show that the values are in range of 11kOhm till 12kohm which means the effect of the voltage applied to the memristor only give slightly changes on the value of the memristor. Noticed that when positive voltage is applied, the conductivity of the device increases thus the memristance is decrease. When negative voltage is applied, the resistivity of the device increase thus the memristance is also increase. This verifies the memristive system on the device. In normalize x graph, we also noticed that the normalized x is at higher state in the beginning. Figure 11 shows the I-V characteristic of the devices and the relationship between charge and flux. The charge and flux curve curves confirms the well known fact that there is a one-to-one correspondence between them in spite of the 1-4 hysteresis effect. Strukov memristor shows lack of flexibility of controlling the device. C:UsersFadzDesktopresultstrukovstrukov4.png Figure 11: Strukov memristor model I-V loop hysteresis and relationship of charge and flux. C:UsersFadzDesktopresultjoglekarjoglekar1.png Figure 12: Joglekar memristor model voltage, IMEM, RMEM and normalized x. Joglekar window function seems to be promising as the existence of controlling parameter. Figure 12 shows the simulation result of memristor SPICE model for Joglekar window function of voltage, IMEM, RMEM and normalized x. Same as strukov memristor, when positive voltage is applied, the conductivity of the device increases thus the memristance is decrease. When negative voltage is applied, the resistivity of the device increase thus the memristance is also increase. The current of the memristor, IMEM is varying up to approximately 300 µA for maximum of 1.2V voltage applied. Joglekar window function give higher current compared to others. It shows that the current in the memristor are much easier to move. The RMEM are within range of nearly 0ohm to 11kohm which give full range of value for the memristor. Figure 13 show the I-V hysteresis loop of the devices and the relationship between charge and flux. The switching behavior is much more sensitive on the voltage level than Strukov w indow function. But, in term of stability, Joglekar window function cannot perform for an arbitrary length of time. This failure is caused by the convergence issue where when the memristor reach w=0 or w=D, the state of the device cannot be further adjusted. C:UsersFadzDesktopresultjoglekarjoglekar4.png Figure 13: Joglekar memristor model I-V loop hysteresis and relationship of charge and flux. Biolek window functions are supposed to solve terminal state problem as in literature [4]. It should solve the boundry problem of the terminal state. Figure 14 and 15 shows the simulation result of memristor SPICE model for Biolek window function. The current of the memristor, IMEM is varying up to approximately 220 µA for maximum of 1.2V voltage applied. The RMEM are within range of nearly 1kohm to 11kohm. Figure 15 show the I-V hysteresis loop of the devices and the relationship between charge and flux. From the figures, we observe that the biolek memristor preserve the highly non-linear device characteristic behavior. In addition, Bioleks model allows for general asymmetric I-V device behavior modeling.

C:UsersFadzDesktopresultbiolekbiolek4.png Figure 15: Biolek memristor model I-V loop hysteresis and relationship of charge and flux. Prodromakis window functions are also said to solve the boundry issue. Figure 16 shows the simulation result of memristor SPICE model for Joglekar window function of voltage, IMEM, RMEM and normalized x. The current of the memristor, IMEM is varying up to approximately nearly 180 µA for maximum of 1.2V voltage applied. The RMEM are within range of nearly 3kohm to 11kohm.

Figure 17 show the I-V hysteresis loop of the devices and the relationship between charge and flux. The hysteresis loop is shown to be asymmetrical while the OFF state of the device is highly non-linear compared with other. C:UsersFadzDesktopresultprodromakisprodromakis4.png Figure 17: Prodromakis memristor model I-V loop hysteresis and relationship of charge and flux. In comparing of I-V characteristic hysteresis loop, as we can see in figure 18, it shows all hysteresis loops for all proposed window functions. By using same parameter we can see the difference in each model. Joglekar window function seems to have a strong memristance compared to others.All models seem to be a good approximation of the measurement of the real memristor produces by HP Labs. But, Prodromakis memristor model satisfies all the prerequisites and improves on the shortcomings of existing models.

In this case, we use prodromakis memristor model and change the value of integer p=1, p=5 and p=10 to see the difference. As we can see in figure 19, as the value of p is increase, the hysteresis is shrinking. Similar with changing the parameter p, figure 20 also confirm that the hysteresis shrinks at higher frequencies. C:UsersFadzDesktopresultdiff frequency1hz-5hz.png Figure 20: Prodromakis I-V Hysteresis Loop when frequency f=1Hz, f=2Hz and f=5Hz. In term of power dissipation, as we simulates our results. We can get the value of maximum IMEM for each model. We can calculate the power by using P=IV equation. Table 2 show the maximum power dissipation for each memristor. Memristor model Max IMEM,  µA Power, W Strukov 100 µA 120 µW Joglekar 300  µA 360 µW Biolek 220 µA 264 µW Prodromakis 180  µA 216 µW Table 2: IMEM and Power dissipation for all at the memristor. As in table 2, we can see that the Strukov model give lowest power which is 120 µW while Joglekar model give much higher power dissipation which is about 360 µW compared to the others. We also noticed that as the memristor model is improves, the power become lesser. Prodromakis give quite good power dissipation which is 216 µW as the best windows function and model as till now. In implementing memristor with analog circtuit, we pick a two simple analog circuit to be tested. Figure 21 shows the SPICE topology of the memristor based integrator op amplifier with the input voltage Vp-p=2.4V from -1.2V to 1.2V and C1=25 µF. Using the memristor model that we create earlier with various types of window functions, we see the difference on the simulated result on each model. The values for the memristor parameters are same for all model with uv, D, RON, ROFF and RINITIAL are 10-10cm2s-1V-1, 10nm, 100ohm, 16kohm and 11Kohm. memristor integrator op amp Figure 21: Memristor Implemented Integrator Circuit C:UsersFadzDesktopresultintegrator+ve integrator .png Figure 22: Positive Integrator simulation C:UsersFadzDesktopresultintegrator-ve integrator .png Figure 23: Negative Integrator simulation Figure 22 and 23 shows the simulation result for the implemented memristor integrator op amplifier for positive input and negative input respectively. In this case, we implement prodromakis memristor to the integrator circuit. As we know, the integrator acts like a storage element that produces a  voltage  output which is proportional to the integral of its input voltage with respect to time. The magnitude of the output signal is determined by the length of time a voltage is present at its input as the  current  through the  feedback loop  charges or discharges the  capacitor  as the required  negative feedback  occurs through the capacitor. For positive starting input, we vary the voltage from 1.2V down to -1.2V and going back to 1.2V over time. When positive voltage are applied in the beginning, the output voltage tend to discharge and drop from 0V to negative voltage and charging back to 0V when the input voltage are drop to negative voltage. The output for neg ative voltage applied from starting point give a vice versa result. The charging and discharge are depends the voltage applied over time and the value of the capacitor. We can say the memristor models give quite good result for an integrator. Figure 24: Memristor Implemented Differentiator Circuit.

As we know, for differentiator op-amp, the magnitude of its output is determined by the rate at which the voltage is applied to its input changes. The faster the input voltage changes, the greater the output voltage becomes. If a saw tooth input signal is applied to the input of the differentiator op-amp a square wave signal will be produced. As we can see in figure 25, the simulation shows a quite good result for differentiator. We also noticed some spikes at the output voltage. Each spikes occurs only occurs the brief moment the saw tooth is changing from one level to the next. The voltage spikes represent a temporary output voltage. Conclusion As a conclusion to this research is that it could bring a new light of familiarization in the integration of memristive components in any kinds of electronic devices that are at nanoscale. It is useful to have a computer model of the memristor as a tool for the analysis of the behavior of the circuits in developing application of this memristor as passive circuit element via simulation. SPICE model will definitely help us to conduct interesting simulation experiments and can be of great importance for such a research in future while the memristor are still hard to fabricate to study the behavior of the circuit. Different models with strong behavior and reason give a lot of benefits in development purpose to create the possibilities of the implementation in an integrated circuit. The possibilities for implementation of the memristor with analog circuit are wide open.

The Fear Of Science :: essays research papers

The Fear of Science To live in the today's world is to be surrounded by the products of science. For it is science that gave our society color television, the bottle of aspirin, and the polyester shirt. Thus, science has greatly enhanced our society; yet, our society are still afraid of the effect of science. This fear of science can be traced back to the nineteenth century where scientist had to be secretative in experimenting with science. Although science did wonders in the nineteenth century, many people feared science and its effects because of the uncertainty results of science. Our thrist for science can be traced back through many decades. However, the nineteenth century society felt that science was a great investment towards a better life. This investment in science gave the nineteenth century society the discovery of light waves and radio waves, the electric motors, the first photograph and telephone, and the first publication of the periodic table. Science also caused an uproar in society when Charles Darwin published The Origin of Species, which became the scientific basis for the study of the evolution of humans. Many people in the nineteenth century detested Darwin's theory of the evolution of man because it went against their religion, which believed that God created the world. Science, soon, developed the big bang theory, which states that earth was created by the attraction of atoms. The nineteenth century society was afraid of science because it contradicted their beliefs, and was afraid that the results of science would lead to the destruction of mankind. Thus, the study of science was limited because of fear of its effects. The fear of the effects of science was expressed in literature. Novels like Dr. Jekyll and Mr. Hyde, the Time Machine, and Frankenstein showed the dangers of science and that science would soon lead to the destruction of mankind. The novel Frankenstein is about a man name Victor Frankenstein who wanted to tamper with life and death by "exploring unknown powers, and unfold to the world the deepest mysteries of creation." (Frankenstein, pg.40) He acquired the knowledge of science when he attended the university of Ingolstadt, and once the knowledge of science was gained, Frankenstein went to his secret laboratory to create a creature with gigantic stature. At first, Frankenstein had doubts about creating a human being; however, with "the improvement which every day takes place in science and mechanics, [he] was encouraged to hope [his] present attempts would at least lay the foundation of future success." (Frankenstein, pg.47) Once Frankenstein created his human being, his dream was vanished because he had accomplished his dream.

History of christmas :: essays research papers

History of the Celebration of Christmas People have celebrated a mid-winter festival since pre-historic times. They marked the beginning of longer hours of daylight with fires and ritual offerings. The Roman festival of Saturnalia -- a time for feasting and gambling -- lasted for weeks in December. Germanic tribes of Northern Europe also celebrated mid-winter with feasting, drinking and religious rituals. It's thought that Jesus of Nazareth was born in springtime. A Pope, Julius I, chose December 25th for the celebration of his birth in the 4th century -- to include a Christian element in the long-established mid-winter festivals. Also in the 4th century, a bishop in Turkey who came to be called St. Nicholas was known for good deeds involving children. St. Nicholas is illustrated in medieval and renaissance paintings as a tall, dignified and severe man. His feast day on December 6 was celebrated throughout Europe until about the 16th century. Afterwards, he continued to be known in Protestant Holland. Dutch children would put shoes by the fireplace for St. Nicholas or "Sinter Klaas" and leave food out for his horse. He'd gallop on his horse between the rooftops and drop candy down the chimneys into the children's shoes. Meanwhile, his assistant, Black Peter, was the one who popped down the chimneys to leave gifts behind. Dutch settlers brought the legend of Sinter Klaas to North America -- where we came to know him as Santa Claus. Clement Clarke Moore first described the â€Å"jolly old elf† with his sleigh drawn by reindeer, in the poem "The Night Before Christmas. Although it was never celebrated in biblical times, Christmas is celebrated in local churches here in Visalia, California in praise of the fact that God loved us so much; he sent his one and only son to earth. He was wholey god and wholey man. Whereas we have succumbed to the temptations of this earth, Jesus was able to overcome all temptations and live a sinless life. He was then crucified as the perfect sacrifice for our sins. One cannot understand why we celebrate the birth of Christ without seeing the other end of his life. He was crucified for our sins and resurrected. Christmas was declared a Federal Holiday in America on June 26, 1870 under the government headed by President Ulysses S.

Theme of Isolation in Gilman’s The Yellow Wallpaper, Steinbeck’s The Ch

Despite differing story lines, Charlotte Gilman’s The Yellow Wallpaper, John Steinbeck’s The Chrysanthemums and Kate Chopin’s The Awakening, depict the same suffering; the isolation that women have been forced to endure throughout history. In the time period that all three characters were placed, it was culturally acceptable for wives to be dominated by their husbands; their responsibility revolving around the needs of their children and those of their spouse. Most women simply did not have a means or an idea of how to rebel against their husbands. The women in all three stories are protagonists who have poor relationships of emotional attachment with their spouses. While the main character of Gilman’s story endures multiple psychotic breaks, Elisa Allen of Steinbeck’s piece is quite the opposite: a very strong and powerful woman. Gilman’s character finally resolves her problems by breaking free, where Elisa remains frustrated with her ignora nt husband and Edna of ultimately escapes through death. This dominance, this isolation, is a cycle maintained by society and the men within it. A cycle that these three short stories prove to be nothing more than destructive and harmful for families as a whole. Following these storylines, there are three key points to address: the relationship between husband and wife, women’s standings within society and finally, the end that it drives these originally normal women to. At first Gilman’s character tries to rebel against her husband through writing, (something she has been forbidden from doing while on her hiatus). In â€Å"The Yellow Wallpaper,† Gilman implies that although her husband is â€Å"very careful and loving† (Gilman 449) she is also her condemner.

Human Element Essay

This study is related to an important topic that influence the evolution of both public and private institutions via improving human resource management and, hence improving the human resource itself, which occupies a vital and outstanding position in the comprehensive development strategies. Also, because of the role that effective human resource plays in planning and implementing development. Therefore, human element is considered an investment in the bright future of the institutions. Human resource is an innovative element that is described as an interactive rather than a rigid element, which is able to coordinate, maintain a balance between the various constituent of production and take the responsibility for the results of operations. On the other hand, external circumstances, such as the economic, political, social cultural and environmental factors, affect human element more than any other element. The researcher has selected Giad Automobiles Manufacturing Co. LTD, as a case study to introduce the influence of human resource development on employees’ performance. The results have been determined based on the analysis of the employees’ responses to the questionnaire that surveyed the employees’ community in the company. The questionnaire has tested the following hypotheses: 1- There is a relationship between the development of human resource management and the development of the working human element. 2- There is a relationship between the development of the human element and the development and improvement of performance in the institution, which leads to an increase in the production and, hence achieving the objectives. The researcher has applied several methodologies, such as case study methodology, descriptive methodology, and statistical analysis. The researcher has confirmed the validity of all the above hypotheses, in addition to the research outcomes that have led the researcher to conclude the study with some suggestions and recommendations.

Organizational Culture of Virgin Group Essay

1. Describe the culture of Virgin group by seven dimension of organization culture. Organizational culture has been described as the shared values, principles, traditions, and ways of doing things that influence the way organizational members act. Actually, it can divided seven dimension of organizational culture which are attention to detail, outcome orientation, people orientation, team orientation, aggressiveness, stability and innovation and risk taking, and now I will use these seven dimensions to describe the culture of virgin. The first dimension used in this culture of virgin is attention to detail. It is the degree to which employees are expected to exhibit precision, analysis, and attention to detail. It is such a culture gives a competitive advantage to companies by helping them differentiate themselves from others. Like this article, the virgin airline has a lot of competitors like 747airline. They provide heterogeneous products and the virgin airline put their selling point to their services that their crews are smiling, cheerful and pleased to help, let the passengers wanting to fly with them again. Also, the virgin America sweeps the travel awards for service and quality. Although their planes are new, with great interiors and entertainment, the great service of its crews is what wins so many plaudits. Furthermore, they employ a general manager in the Caribbean. He tried to change the way things were done, discouraged the staff from drinking their guests that reducing the staff morale. As he didn’t get the degree on attention to detail, then he was being replacement. The second dimension in this culture is people orientation. It is the degree to which management decisions take into account the effects on people in the organization. It emphases on individual rights and expectation of treating people with respect and dignity. In this article, when the author was running Virgin Records, a member of the talent-scouting team was stealing and selling boxes of records to local secondhand shops. But he didn’t fire the staff and just gave him a severe warning and a second chance. He expected the staff to learn from his mistake and get back to doing his job. As the experience of the author that he fell foul of the customs and excise people as trying to bring records into the UK. He was given a fine, a second chance and have tried to make the most of it ever since. This has made him much more accepting and forgiving of people’s mistakes. Also, the virgin airline treats their staff as family units and makes them feel that their company is their second home. They will hold parties in the weekend, make sure all the staff can participate the parties and help them build the relationship between staff and manager. That is how the virgin airline treating their staff. The third dimension in this culture is team orientation. It is a degree to which work is organized around teams rather than individuals. It is collaborative and emphases on cooperation among employees. In this article, the writer mentioned about how to be a good leader to lead people well. He said that a good leader must know the team, its strengths and weakness; socializing and listen to the team is the key of being a good leader. A good leader can led their teammate well, can motivate the staff morale and build the relationship between the team. He also said that a bad leader can destroy a business very quickly. As they employed a general manager in Caribbean who tried to change the way things were done. The manager discouraged the staff from drinking with guests that decreased the staff morale and broke the trust of management. So they replace the manager and restore the staff morale and the sense of management’s trust which had been broken. The fourth dimension in this culture is innovation and risk taking. It is the degree to which employees are encouraged to be innovative and take risk. Through this article, Brett Godfrey showed his business plan to the author, which outlining the start-up of a low-cost carrier in Australia to take on Qantas and Ansett in their domestic market. He has expanded Blue and its sister airline to the United States, New Zealand, Thailand and South Africa. The company give them brand support and the space to go build the new business themselves like Virgin Active. Also, Matthew Bucknall and Frank Reed had bought out some innovative idea like the idea of a family-friendly health and fitness club in 1999. These planning and ideas are innovative, but at the same time they need to take the risk on running the ideas and planning. In this article, we can find out four dimension of organizational culture. A top company must have strong organizational culture that employees are more loyal than weak organizational culture, creates a stronger employee commitment to the organization, and the strong organizational culture is associated with high organizational performance. Also, if the value of the culture is clear and widely accepted, employees can know what they are supposed to do and what expected to them, so they can act quickly to take care of problem. 2. How culture affect the manager? A culture usually reflects the vision of organization founder. They will articulate the vision of what they want the organization to be. The small size of most new organizations makes it easier to instill the vision with all organizational members. Also, organizational practices are also one of the impacts on culture. They can find out the information about the organization and determine the most suitable for organization through practices. The top management behavior has a major impact on culture too, that the action of top management can lead to undesirable outcomes. Organizational culture can divide into four types. They are open systems, human relation, internal process and rational goal. A culture will predominately affect the manger in four ways, which are controlling, leading, organizing and planning. In the leading of the management, the mangers are able to use democratic leadership style that allows employees participate in decision-making progress, but not only individuals in the open systems and human relation culture. Through these two types of culture, the mangers require visionary leadership, responsive behavior and also tend to be participative, considerate and supportive. Also, the mangers in rational goal culture are also able to use democratic leadership style and tend to be directive, goal oriented and functional. On the other hand, the mangers in the internal process culture will be more likely to use autocratic leadership style that they are tend to be conservative and caution. In the planning of the management, they will more likely to take the risk of the plan in open systems culture in the large extent, which this culture is emphasis on creativity and innovation that the employee will have some innovative idea when planning. In rational goal and human relation culture, the manger will take risk on planning in the small extent. But in the internal process culture, the manger are not willing to take the risk on planning, which their company are conservative and cautious. In the human relation and open system culture, they will likely develop the plan by team, but the mangers will likely develop the plan by individual in the rest of the cultures. In the controlling of managers, the control system will be more flexible in human relation and open systems culture, which likely allow employees to control their own action. But in the rest of the cultures, the control system will be inflexible that the managers need their employees follow their rules and procedures. In the open system culture, the manager may able to take the risk to produce the product if exceeding the budget. On the other hand, the manager in internal process culture will prefer cutting the cost or will not produce the product rather than taking the risk to release the product into the market. In the organizing of the mangers, their employees can have more autonomy in their jobs in the human relation and open system culture, but less autonomy of employees in the rest of the cultures. Through the rational goal and internal process culture, they will be able done their task by individual rather than team. On the other hand, in human relation and open system, they will prefer to finish the task by team compare to individual and their manager will be likely being decentralization, that increase the decision-making authority of employees, but the rest of culture not. A culture will affect the mangers what they can or cannot do and how they manage. A good manger should know the culture of their companies deeply, that can help them to know what to do and not do and identify their role on managing a team or company.
