The Right to Privacy Essay examples -- Bill of Rights
Individuals are born with certain liberty and freedom. Some freedom are being protected by the Bill of Rights, like freedom of religion, speech, press, and assembly, and some are not. Privacy is one of the rights that was not mention in the Constitution. The definition of the right to privacy is the right to be left alone without governmentââ¬â¢s intrusion. Throughout history the Supreme Court has been ruling in favor of the right to privacy like in the cases of Griswold v. Connecticut, Roe v. Wade, and Lawrence v. Texas. People who believe that the Constitution should be taken literally protest that this is an act of judicial activism, or judiciary misuse of political power to implement their own opinion on federal laws. Then there are those who believe that the judiciary pursuit justice when protecting individualââ¬â¢s the right to privacy. In this paper I will argue that the right to privacy is an example of the judicial authority in pursuit of justice because it is inferre d in the Constitution, itââ¬â¢s a just liberty, and itââ¬â¢s in the state of nature. The judiciary authority is responsible for individualââ¬â¢s right to privacy because it exists in the state of nature. Does the Constitution protects privacy? Justice Douglas answered yes. In the court case of Griswold v. Connecticut, Griswold offered informations about birth control to married couples. His action violate with the state law of Connecticut which prohibited any use of device that will prevent contraception (261).

Huckleberry Finn Essay
Theme, structure and social characteristics as the literary elements, highlighting the spiritual growth of the main characters in ââ¬Å"My Name is Asher Levâ⬠, ââ¬Å"Emmaâ⬠and ââ¬Å"Huckleberry Finnâ⬠The present paper is designed to discuss three novels about moral maturation and the growth of self-awareness, ââ¬Å"Huckleberry Finnâ⬠by Mark Twain, whose protagonist is Huckleberry Finn, Jane Austenââ¬â¢s ââ¬Å"Emmaâ⬠, named after the protagonist and ââ¬Å"My Name is Asher Levâ⬠by Chaim Potok, whose main character is Asher Lev. Notably, the authors necessarily indicate the protagonistsââ¬â¢ names in the titles, underlining their moral and psychological development as a central plotline. The literary elements of theme, structure and protagonistââ¬â¢s social characteristics actually strengthen the readerââ¬â¢s understanding of the characterââ¬â¢s spiritual growth: Levââ¬â¢s novel demonstratesââ¬â¢ the protagonistââ¬â¢s liberation from the community bonds through the lens of the theme of social pressure, Twainââ¬â¢s writing ââ¬â the progress of Huckââ¬â¢s humanistic views underlining the theme of slavery, Austenââ¬â¢s work ââ¬â Emmaââ¬â¢s psychological maturation, through prioritizing the theme of marriage, moreover, all works by their structure provide the mistakes made by the protagonists on their path and thus make clear to the reader that development is not a smooth and gradual process, whereas the change or stability of sociological characteristics pay readerââ¬â¢s attention either to the connection between self-awareness and social position or to the purely inner revolution. The characters actually perfect very distinct aspects of self awareness: Emma, for instance, overgrows the selfish and infantile girl, whose main interest is manipulating the othersââ¬â¢ fates (as she appears at the beginning), Asher Lev realizes that he is actually an independent personality rather than the subject of the Hassidic community after being judged for depicting the his motherââ¬â¢s anguish, whereas Huckleberry Finn, who has never considered carefully the issue of racial equality, begins to realize his humanistic views and oppose the oppression of slaves and the split of their families. Due to the fact that the major theme in ââ¬Å"My Name is Asher Levâ⬠is community bonds and the conflict itself develops in terms of the weakening of the commitment to the groups of Hassids (Walden, 1985), the protagonist, who is a bright and unordinary individuality, should ascend over the blind observance of community tradition and learn to distinguish himself from the group. Therefore, his development is associated with individuation and learning of his ego and the religious conflict results in the development of Asherââ¬â¢s ability to assert his self: ââ¬Å"So it is time for the defense, for a long session in demythology. But I will not apologize. It is absurd to apologize for a mysteryâ⬠(Potok, 1998, at http://search. barnesandnoble. com). The theme of marriage as the leading one in ââ¬Å"Emmaâ⬠is also related to the main characterââ¬â¢s development: whereas at first, Emma views marriage as a game, popular in her environment, she is still not infantile to understand that this specific type of partnership is based necessarily on strong affection after developing the feelings for her brother-in-law; whereas at the beginning she has fear for the responsibility associated with marriage. The theme of slavery also supports the readerââ¬â¢s understanding of the young protagonistââ¬â¢s moral growth in ââ¬Å"Huckleberry Finnâ⬠: ââ¬Å"Iââ¬â¢m low down; and Iââ¬â¢m a-going to steal himâ⬠(Twain, 1999, Ch. 33); as one can understand, Huck no longer views Jim as property, but in order to persuade Tom, he recognizes his own inclination to wrongdoing and takes entire responsibility for the stealing the slave. The structure of the stories is generally similar: the greatest part of the plot is dedicated to depicting the behavioral imperfections of the protagonist, so that the reader can feel the protagonist is an ordinary person, whose growth is based upon his/her own mistakes. For instance, ââ¬Å"Emmaâ⬠at first depicts an arrogant and class-conscious girl saying ââ¬Å"The yeomanry are precisely the order of people with whom I feel I can have nothing to doâ⬠(Austen, 2001, Vol. 1 Ch. 4) and throughout the first two parts she acts as a quarrelsome person, whereas her later reasoning can be characterized as wiser: ââ¬Å"I think Harriet is doing extremely well ââ¬Å"(Austen, 2001, Vol. 3, Ch. 28), i. e. she approves of her best friendââ¬â¢ marriage to the farmer, having got the idea of love and letting it in. Beyond mistakes, Potokââ¬â¢s and Twainââ¬â¢s protagonists also encounter difficulties and adversities, which shape their outlooks; for instance, Levââ¬â¢s story can be divided into three parts (Walden, 1985): period of the teenage conflict with the environment, movement toward the goal in Kahnââ¬â¢s studio and the resolution of the conflict and individuation (Potok, 1972). Huckââ¬â¢s moral development is less gradual and actually consists of several insights: 1) first encounter with Jim as a fugitive slave and the initial desire to help him; 2) The loss of the companion after meeting the ââ¬Å"aristocratsâ⬠and Jimââ¬â¢s imprisonment in Phelpsesââ¬â¢ house. Finally, social characteristics of the protagonists are quite expressive themselves and point actually to the qualities to be changed. For instance, Emma is introduced as a girl with a degree of self-importance and class-based prejudice because of her upper class identity, but later she begins to understand her friend Harriet in her love for Martin and thus grows more open-minded; furthermore, her maturation is accompanied by the change of social characteristics, as Emma accepts Knightleyââ¬â¢s proposition Huck Finnââ¬â¢s social characteristics remain practically the same, as the author seeks to maintain the readerââ¬â¢s focus on the advancement of his moral qualities, so that the adolescent still remains to some extent uncommitted to social norms (ââ¬Å"Aunt Sally sheââ¬â¢s going to adopt me and sivilize me, and I canââ¬â¢t stand itâ⬠(Twain 1999, Ch. 43), in spite of having developed his distinct attitude towards slavery. Asher Lev, in turn, drastically changes his social identity: the growth of his self-awareness and self-identity result in his alienation and separation from the community. To sum up, the readerââ¬â¢s understanding of the protagonistââ¬â¢s path toward self-awareness is to great extent manipulated by the authors: Jane Austen, Chaim Potok and Mark Twain design the plot structure, which underlines the failures and subsequent insights of the protagonist, embed the central theme into the main characterââ¬â¢s spiritual growth and substantially change the protagonistââ¬â¢s social features, except Huckââ¬â¢s case, in which the focus on morality shift is broadened through remaining social characteristics stable.

Should the Government Regulate Our Health
Should The Government Regulate Our Health? Posted: 01/29/10 10:58 AM ET Get Healthy Living Alerts Sign Up Submit this story I was in my late 20's when I walked into a dialysis clinic for the first time. The interior of the waiting area was worn, with beige paint peeling off of the walls. As I waited awkwardly to find out where my patient was my attention was drawn to a sign that read, ââ¬Å"Did you know that [a popular fast food sandwich] contains 1020 milligrams of sodium? â⬠Salt can be bad. But it sure tastes good.Ask the millions of Americans who consume large amounts of salt in their diet, much of it from processed foods. Sodium consumption in excess is linked with a number of health problems, including high blood pressure, kidney disease and various forms of heart disease. New Yorkers have recently learned about the detriments of salt. Mayor Bloomberg has launched an initiative to reduce the amount of sodium that people get from restaurant chains and food producers by ask ing them to voluntarily cut the amount of this now ill-thought of mineral.When in New York City a couple of weeks ago, my husband and I could tell that restaurateurs are listening to Bloomberg. When eating out, we noticed that our food was, well, less tasty. But maybe it is worth it. A recent New York Times article, which summarized findings from The New England Journal of Medicine, suggested that if Americans reduced salt intake by a half a teaspoon a day the nation would save 24 billion in health care costs. In the current political climate, many of us are acutely aware of issues related to the rising costs of health care.But is government intervention the best way to proceed? Although a government middleman might be a good option, I wonder why we aren't putting more pressure on physicians to counsel their patients on dietary strategies to reduce sodium intake. Research suggests that American physicians are less likely than their European counterparts to discuss behavioral interve ntions with patients and are more likely to rely on the prescribing of medications. Regarding diet and hypertension, a recent study suggests that physicians offer little counseling on how to lower blood pressure numbers through lifestyle changes.Not only do discussions regarding health behaviors result in patient satisfaction, such discussions comprise the inherent values of doctor-patient relationships. We seek medical care not only for lab results and prescription refills; we look to our doctors for advice and support. However, in a day and age in which technology and insurance mandates are interlopers in the patient-physician dyad, we have lost the personal connections and source of wisdom that people often crave.In fact, the relationship between many of us and our physicians is dysfunctional. Doctors are overwhelmed and receive less respect than ever before in the history of modern medicine. As patients, we have submitted ourselves to the less personal nature of medical encounte rs. Maybe if we demand additional support from physicians (and advocate for additional backing of our doctors regarding the freedom to make medical decisions and limiting intrusion by managed care companies) we can get what we need in order to change our behaviors.Of course, we are all ultimately responsible in how we choose to care for our bodies. But maybe if we can learn to trust our physicians again (and they work to earn that trust), we don't have to reduce healthcare issues and healthcare costs in this country to something like eating salt.

Booker T. Washington, W.E.B. Du Bois and the Struggle
The book Booker T. Washington, W. E. B. Du Bois and the Struggle for Racial Uplift was affectively written by Jacqueline M. Moore and published in 2003. This book review will look at the following themes, Washington being a gradualist while Du Bois wanting confrontational immediacy, and the idiom, ââ¬Å"if you canââ¬â¢t beat them join them. â⬠What is also great about the book is that it starts with telling us about both philanthropistââ¬â¢s childhood to effectively reveal where each got their philosophies and unique characteristics and traits.The injustice of racism and its evident role in some of Americas most prominent political and social aspects have perpetuated rigorous and squalor lifestyles for those of non-Caucasian ancestry. Jacqueline Moore clearly states evidence how white people have such a long history of being the dominant group and why it is so hard for blacks to assimilate. In the book the writer simply told us a story of 2 menââ¬â¢s journeys for racia l uplift and wanted us to decide the theme for ourselves, telling both sides of the story in order to let us choose which of them we might agree with more.The author did a good job letting us know Washington and Du Boisââ¬â¢s goals. The style of the novel is interconnected with its themes. In the novel, not only does Moore convey the ideas and concepts of Booker T. Washington and W. E. B Dubois, but Moore also illustrates the theories of which consists of gradualism and immediacy. ââ¬Å"Washington was a gradualist, and Du Bois favored immediacy. Washington advocated economic advancement and self-help; Du Bois favored political advancement. â⬠(p. 7) Washington tries to possess the concept that, if you canââ¬â¢t beat them join them. This is one of the examples in the novel that Jacqueline Moore clearly and affectively states as evidence to one of the themes. The tone of Mooreââ¬â¢s Novel is optimistic and assertive, which is evident when she says that ââ¬Å"â⬠¦ alt hough it was true that blacks had to make efforts to help themselves, without the support and encouragement of the white community and the elimination of discriminatory barriers, progress was not possible. (p. 72) Mooreââ¬â¢s writing proves its effectiveness for it essentially explains Duboisââ¬â¢s theory of what blacks need to do too pursue a better life and achieve self-actualization that promotes higher possibilities and is free from lowering standards as he addresses his purpose, indicates his broad audience, and infuses a unique writing style that employs an in-depth point of view and an optimistic tone from Du Bois. ââ¬Å"The difference was in the emphasis each man placed on his preferred method.Washington argued that industrial education should come first so that southern blacks could gain basic schooling and useful skills with which to make something of themselves. Du Bois argued that without higher education for blacks there would be no black teachers for the industr ial schools and therefor no chance for blacks to improve. â⬠(p. 61) Again, the writer states the goals of the 2 men to make sure the readers are able to convey the information to their own understanding.Moore fills the readers with the knowledge that the white society of the past was philosophically corrupted and degraded the worth of black individuals due to white supremacy and the lack of cooperation from the whites, which depressed blackââ¬â¢s motivation to instill within them their goals and expectations. The key to eliminating discrimination was to get the government to take initiative to end discrimination of the black race, but as time progressed, rebellious natured individuals presented their disapproval for this racial uplift and started clans like the KKK in order to discourage blacks from earning political rights. As their situation grew increasingly desperate, many poor blacks lost faith in the possibility of integration that both Washington and Du Bois held out as the ultimate goal. â⬠(p. 94). Supporting my thesis, many blacks have lost faith for racial uplift and started to think they couldnââ¬â¢t beat the white supremacist. ââ¬Å"Eventually, after many struggles, the International Migration Society did send a group of 200 emigrants to Liberia in 1895 and another 321 in 1896. (p. 100) The book also did a good job stating statistical facts. One of the class discussions that we had was ââ¬Å"Was it too early to migrate back to Africa? â⬠We asked ourselves this and had a big debate over it, but the novel states that only about 1,000 black people took the ship back to Africa while the population of blacks at the time was somewhere around 8,000,000, that is not even 1 percent and most couldnââ¬â¢t even afford it.It was important that the book stated facts showing that although blacks tried very hard to become part of the dominant group, they did not have the tools and money to do so as the whites were very powerful when it came to black rights. They did not understand how hard the standard of living was for blacks, so the people of color continued to be ridiculed by the army of brainwashed drones, who stood tall at the pinnacle of ignorance. Overall the book did a good job adding to my understanding of the subject.A lot of what I read in the book was learned in our in class lectures giving me a head start. Moore wishes to guide her readers out of their blind state of mind and use the perspective of the two philanthropists in order find their way through the often dark and bleak aspects of racial uplift. Before reading the book I knew little to nothing about Washington and Du Bois, but affectively it has managed to reveal all I need to know about the two and all that they have done in their efforts to achieve justice.

Object oriented development Essay Example | Topics and Well Written Essays - 1250 words
Object oriented development - Essay Example It is an easier way to keep track of program flow and much organized than the traditional "spaghetti codes" produced by unstructured programming methods. In 70's, a new programming technique began to gain popularity as a "top-down" approach to program design. This is a technique where a program designer maps out large-scale structure of a program and breaks them into smaller operations. These smaller operations will be tested or debug separately and connect them together into the entire program. Structured programming facilitates easy understanding of smaller pieces of code without having to understand the whole program at once. By the end of the 20th century, mainstream programmers realized the significance and value of structured approach began to apply the concept in high-level programming languages. In the middle of the 1980's, another concept in program development made its way to become the dominant programming methodology. Mainly influenced by C++ and the popularity of GUI (Graphical User Interface), Object-oriented programming became the most sought after programming method to date. The objective behind object-oriented programming is to view computer programs as a collection of individual units or objects that is capable of receiving messages, processing data, and sending messages to each other. This is different from the belief and practice that a program is just a compilation of functions and procedures or a list of commands for a computer to follow. Object-oriented programming is broadly accepted in large-scale software development. It is adaptable, easy to learn, simpler to develop and maintain, and easier to manage. The fundamental concepts of OOP (short for object oriented programming) are class, object, encapsulation, inheritance, abstraction, and polymorphism. Class is a unit of data and function for a particular thing. For instance, a "class of students" might be a set, which include different type of students (male, female, black, white etc.). An Object is an occurrence of a class, a run-time demonstration of a specific pattern of a class. For instance, the gender "male" and "female" as a subclass and "Alfred" the student as an object in the class of students. Encapsulation is a type of privacy to ensure that an object can be change only through established channels within a class. It simply means packaging the data and related functions into one unified unit, a class. Inheritance- is a mechanism for creating subclasses; it provides a way to define a subclass or an extension of a universal class. For instance, as students, class is a subclass of year level class and gender of student in a class is a subclass of the class students. An Abstraction is the ability of a program to disregard the details of an object's class or subclass and si mplify it into a more suitable general level. For instance, "Alfred" the students may be abstracted to a more generic level as year level super class. Polymorphism is a varying behaviour depending on the class in which the behaviour is call upon to act. This is to say that two or more classes can answer independently and in an entirely different way to an identical message.

Should American Football be banned from Highschool Research Paper
Should American Football be banned from Highschool - Research Paper Example The issue has been met with opposing opinions from those who support the sport and want such an activity to continue, while there are those that strongly oppose the same. In this section, I shall discuss why school administration boards across the country have been considering the prohibition of the sport on their grounds. Unsurprisingly, supporters of the stand that American football should be banned come from adults who are mostly parents of the students. American Football as a Discriminating Sport According to David (105), American football is a gender discriminating sport. The parties particularly interested in playing the sport and those who enjoy the same the most are the males. The sport has been described as a ââ¬Å"masculineâ⬠activity and female students are not likely to benefit from the sport in the same way that their male counterparts can. It is also thought that female students are not likely to benefit from the sport. They are not likely to hone any beneficial s kills from playing the game, at least not physically. The Injuries Suffered by Football Players One of the obvious injuries that may be suffered by American footballers would be head injuries. The seriousness of the risk faced by these players has lead the District of Columbia to ban sports that result in concussions, or at the very least, expose the youth to such threats (between 2009 and 2011). While suffering concussions may not seem to be that serious to some, because head bumps can be helped with a pack of ice, the threat of head injuries can definitely lead to really serious health conditions that can affect a player for life. The trauma however, can manifest later on in the life of the injured player and can be the explanation of ââ¬Å"neurodegenerative disease similar to Alzheimerââ¬â¢sâ⬠(Trotta and Ingles). Health conditions related to head injuries include dementia and Alzheimerââ¬â¢s itself. Problems such as fractures to the skull are also highly likely and t he presence of the skull itself and its ability to cushion the brain from injury is not enough. Serious brain damage is possible (Reed). There has also been research to suggest that the more concussions a player suffers, the more likely would depression kick in. Other injuries to be suffered by such football players include ââ¬Å"cervical spinal cord injuries.â⬠It has been known that in the United States, players from Louisiana suffer mainly from this kind of injury (Lawrence et al) Because of the alarming health risks that football may bring, fifteen states have issued laws banning such dangerous sports (Trotta and Ingles). It has been suggested that the best way to deal with preventing such serious injuries would be to invest in the sports equipment. Supporters of the sport should look into providing improved designs of head and mouth gear for the players, to ensure that the playersââ¬â¢ gear could withstand injuries to be encountered on the field (Trotta and Ingles). An other solution to the problem would be to educate the players themselves on ââ¬Å"safe tacklingâ⬠methods in order to prevent injury and how these players can best use their head gear in the safest way possible. Unfortunately, according to a study by Lawrence et al., a significant number of players use the top of their helmets in tackling their opponents. This is one of the most dangerous tackling methods, and is actually illegal. However, an alarming majority of player participants in the

The Influence of Materials Properties on Structural Form and Behaviour Essay
The Influence of Materials Properties on Structural Form and Behaviour - Essay Example As the discussion stressesà during the selection of materials to be used for engineering purposes, certain properties that include tensile strength, impact strength, as well as hardness is essential in indicating how suitable the selection for the material is, although the engineer has the obligation of ensuring that radiography together with other properties for the material are in line with required specifications.From this paper it is clear thatà there has been an increase in popularity of plastics and polymeric materials in engineering. As much as these are inferior to majority of the metallic materials as far as temperature resistance and strengths are concerned, these have been used in corrosive environments as well as in other areas that require minimum wear, for example in small gear wheels that were initially manufactured from hardened steel, are currently produced from Teflon or nylon.à The performance of these materials is satisfactory; they are quiet and are in no n eed for lubrication. In this respect, therefore, prior to selection of material or even the designing of components, there is need for an individual to have sufficient knowledge of the process requirements, the limitations of operation like the non-hazardous and hazardous conditions, the continuous and the non-continuous operations, raw material availability together with the availability of spares and other alternate material.a
