Integrations and reflection - Essay Example My skills and abilities to deal with numbers have also increased and I am now able to interpret figures well. This course has made me more confident in terms of handling statistical tools. During this session I was asked by my teacher to create a project that would encompass all the statistical methods and this would be used to analyze the data of real life organization. I tried my best to fulfill the conditions of the project but somehow I feel that I could have done better by incorporating more of statistical methods and getting them approved by my teacher before applying them on any real time data. I did not understand three topics related to the course that is ANOVA and regression, statistics survey, and probability. These topics I feel were not well explained by my teacher. These topics need further improvement according to me and I feel that it would be more beneficial if more problems are given in the class to be solved (Johnson & Kuby, 2011). These problems should be diverse so that students are able to apply maximum methods to derive solutions and interpret the results. In any course it is very essential to build a strong knowledge base as on it lays the future progress and development. I feel the best way to measure to future progress is by evaluating the level of understanding. If I opt for a career related to statistics then my marks would be a measuring tool for the outcomes of this course. The other factor is that this course would enable me to think towards a direction and choose a career that would help me to explore the skills that I gained through this course. I was able to achieve the outcomes of the course however I feel that I could have been more proficient with the statistical tools and methods. I was able to understand the different approaches in statistics and would be able to deal with problems efficiently in the future. The other learning outcome that I achieved is that of

Software Engineering Essay Example for Free

Software Engineering Essay Like most of the things, quality attracts the person it signifies the performance and appearance of the product. It matters a lot of the standards in a business for the outcome of the products. Just like this, Software has also good quality requirements and better ways to ensure its outcome. The following are the measurement methods and acceptance criteria for assessing the characteristics of the software: 1. Software Engineering Culture and Ethics Ethics can play a significant role in software quality, the culture, and the attitudes of software engineers. 2. Value and Costs of Quality The notion of â€Å"quality† is not as simple as it may seem. The customer will have some maximum cost in mind, in return for which it is expected that the basic purpose of the software will be fulfilled. 3. Models and Quality Characteristics [Boe78; McC77] ISO/IEC has definedthree related models of software product quality (internal quality, external quality, and quality in use) (ISO9126-01) and a set of related parts (ISO14598-98). Software Quality Management Processes defines processes, process owners, and requirements for those processes, measurements of the process and its outputs, and feedback channels. It involves: (1) Defining the required product in terms of its quality characteristics. (2) Planning the processes to achieve the required product. Through this we can assure Software Quality, this means ensuring that the problem is clearly and adequately stated and that the solution’s requirements are properly defined and expressed. And then we can verify and validate for assessing the intermediate products. For purposes of brevity, reviews and audits are treated as a single topic in this Guide. Five types of reviews or audits are presented in the IEEE1028-97 standard: 1. Management reviews 2. Technical reviews 3. Inspections 4. Walk-throughs 5. Audits Of course the management also has to review the software, the purpose it is to monitor progress, determine the status of plans and schedules, confirm requirements and their system allocation, or evaluate the effectiveness of management approaches used to achieve fitness for purpose. After this is the technical review to evaluate a software product to determine its suitability for its intended use. During the technical review the management should also inspect to detect and identify software product anomalies. The audit is to provide an independent evaluation of the conformance of software and processes to applicable regulations, standards, guidelines, plans, and procedures. The definition of Software Engineering is broad, so it needs to discuss its disciplines which it shares common boundary. These are two Related Disciplines: 1. An informative definition (when feasible) 2. A list of knowledge areas Related Disciplines Areas: 1. Computer Engineering computer engineering embodies the science and technology of design, construction, implementation and maintenance of software and hardware components of modern computing systems and computer-controlled equipment. 2. Computer Science identifies the following list of knowledge areas (identified as areas in the report) for computer science. 3. Management 4. Mathematics 5. Project Management – is the application of knowledge, skills, tools, and techniques to project activities to meet project requirements. 6. Quality Management is defined in ISO 9000-2000 as â€Å"coordinated activities to direct and control an organization with regard to quality.† 7. Software Ergonomics the field of ergonomics is defined by ISO Technical Committee 159 on Ergonomics as follows: â€Å"Ergonomics or (human factors) is the scientific discipline concerned with the understanding of the interactions  among human and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance. 8. Systems Engineering is an interdisciplinary approach and means to enable the realization of successful systems.

Importance of Reputation in Othello

Importance of Reputation in Othello Reputation is very important when one needs to know whom to trust and what judgments can be made about a reason. The reputation of three characters in the play Othello by Shakespeare plays important role in determining the eventual results of the play. The end results of the play would have been different if Iago had not been known as a honest person or Othello not being a noble military man and also if Cassios reputation had not been tarnished. Iago himself states that, reputation is an idle and most false imposition, often got without merit and lost without deserving (Havoc, par.7). Reputation would bring about good judgment, both in the decisions made and those others makes about a given character. A hero is someone who confronts issues beyond the social rules, who in their physical journey encounters fundamental conditions of life and understands The Epic of Gilgamesh covers every aspect of great epic literature, that is fantastic geographies and exotic characters; tiresome quests and hard journeys; victorious battles with monsters, supernatural beings and natural forces. Literatures have been used throughout history of civilization to express a variety of cultural issues. The episode of Mesopotamian Noah, as is evident with, the character Utnapishtim, who was advised to build a great boat and fill it with animals and his family to escape flooding, has been related to biblical Noah and therefore the Epic of Gilgamesh has received biblical critics (eNotes.com, par.1). The social structure and values of society can be seen throughout the actions of Gilgamesh and his people. This epic brings forth the perception of the ancient Sumerian and Babylonian cultures. Gilgamesh is shown to be struggling against the gods, natural forces and his own mortality and this reflects his ones efforts to find rest in society and universe. Importance of Reputation Gilgamesh was a strong powerful leader who was more of God and stronger than any other king alive. He treated his subjects harshly and unkindly. This made people to ask the god of Uruk to create an opposing ruler who has equal strengths to Gilgamesh so that they might even be left to rest in peace. Enkidu was then created and he had scaring features that destroyed his reputation and he was referred to as wild man, this made Gilgamesh to tame him and even put off his marriage with the goddess of love. Gilgamesh was concerned about his reputation after fighting with Enkidu, they became friends and travel together for fights, he aimed at establishing eternal reputation saying he wants to leave behind a name that endures(pg.71). Gilgamesh would get ready for the journey by offering sacrices to Shamash so that he may get loyal friends, obtain weapons and he also sought intervention from her mother who had then adopted Enkidu. In the epic of Gilgamesh, the gods possessed great powers that showed social values that were adored in the society. Gilgamesh was characterized by military nature and strong social standing for the people he represented and these revealed qualities of a good warrior that is valued within society. In the beginning of the story, Gilgamesh was a bad king, but later he became determined, considering his internal feelings and questioned his eternal mortality. It was the power of gods in the society, but not the population, that redirected his actions so that he may not harm the people. Gilgamesh being a brave warrior, his people had confidence in him and they would fight fearlessly and would emerged victors with everyone they fight with. They fought with a mighty beast Humbaba and defeated him; this shows that even such a mighty enemy was still no match for Gilgameshs extreme skill. It is said that, Gilgameshs tribe is unconquerable, and aroused by small insults, (par. 2). In this regard Gilgameshs virtues as a awesome leader is revealed. He proved his skill of a warrior and leadership ability beyond imagination when he rws the boat across the sea faster than a boat man. For one to be a good leader, one has to prove their powerfulness and ability to defend their people always. Gilgamesh revealed this throughout the entire epic. His intelligence is shown when he sought advise and counseling from his mother who is wise AND worries not (Tramp, par4). His reputation as a leader who sought no fame but fought for whole his kingdom is a true characteristic of a selfless leader. Reputation plays an important role in the play Othello that was written by Shakespeare. It is evident that Iago wouldnt have been able to do what he did without such a good reputation of honesty. In fact Othello praises him and because of Iagos reputation Othello takes caution when he is talking. In the play Iago deceives Othello and all people through his reputation. In the other hand, Othello engages his reputation in every scene of the play, also the varying of Cassios reputation plays an important role in the play. Othello revealed no nonsense military general characters that eventually lead to death of Desdemona. When he heard from Iago that Cassio and Desdemona were cheating on him, he became extremely upset and anxious that he couldnt think clearly and wanted to kill her. He said that I will chop her into messes! Cuckold me? (123 helpme.com, par.3). Othello couldnt believe that Desdemona could deceive him and cheated on him. Because of his reputation, he was unable to throw wo rds on her in that situation. He kept anger in his heart since he knew that his reputation is going to be tarnished when it comes out that his wife was unfaithful to him. Reputation meant a lot to him and this is shown when he said that for naught I did in hate, but all in honor (123helpe.com, par3). His reputation was his treasure in relation to his position as a general and respect that he had from ranked below and above him. At the end of the play Othello died while trying to keep his reputation. In the play, lagos reputation is exact opposite of his true nature. His reputation was being an honest man. He made all people to believe that he was honest as it is written of him as O, thats an honest fellowà ¢Ã¢â€š ¬Ã‚ ¦, you advice me wellà ¢Ã¢â€š ¬Ã‚ ¦ goodnight honest lago (123helpme.com, par.2). This made Othello to declare his loyalty and friendship to him. He would completely make everybody to strongly believe that he had very good personal qualities and honest person. Therefore, he often uses these qualities to gain favors saying that devils would show good characters first before their inner characters are revealed. Through all these, Lago was able to deceive Othello and made him believe that Desdemona was really unfaithful to him. Desdemonas innocent and pure reputation is destroyed by Iago when he had Othello to begin doubting her. His reputation protected him from being confronted by Othello throughout the scene. No one could doubt Iago, even if it ever came out that he was setting up to destroy Othello, Desmona and Cassino. He always controlled Othellos mind using his reputation to accomplish whatever he intends to do. Because of his honest reputation, he was able to damage Cassios reputation and eventual death of Desdemona and Othello. Throughout the scene, Cassio changes his reputation often and these took a major part in the play. He is shown as an honest, loyal and just soldier but his reputation comes to a halt when he gets drunk. Cassio depended on reputation in order to accomplish his missions, but when he was lowered from his position, his behavior changed and he was afraid of Othello. He said that I have lost the immortal part of myself, and what remains is bestial(123helpme.com, par.4). His reputation was spoiled after being demoted and Othello was not impressed and could not hold him as a friend anymore. Because of his drunkenness, Iago was able to convince Othello that he had affairs with Desdemona and were cheating on him. Othello told Casino that I will make thee an example, (123helpme.com, par.4) and these openly revealed to him that he no longer earns trust from Othello, his friend. As he tried to resolve his differences with Othello, Iogo would come in and disrupts everything. Iago made spoilt reput ation of Cassio has his stepping stone in accomplishing all his plans. Oedipus being the main character is said to have met a tragic fate Oedipus is portrayed as a rash, unreasonable and overly confident king, who is always trying to keep up with his unavoidable fate. In the beginning of the play he is described as a great king and a ruler of the people of Thebes. When the people of Thebes came to him with a problem, he would solve it being a determined king. When the city went through problems he was eager to solve it in order to gain reputation and become a hero, he always looked for such opportunities. The people appreciated his greatness as a king and would always turn to him to find a solution to their problems. Oedipus from the beginning is considered as a great celebrity and a national leader of a state during the time of crisis. Thebes was attacked by plagues and they believed it was a manifestation of the fatal forces of the universe they lived. Because of his wisdom in dealing with adventurous things, people loved, acknowledged and respected h im. They told him that we judge you as the first of men in what happens in this life and in our interactions with the gods (Johnston, par. 20). He was a person who had self assurance and confidence and ready to face any crisis taking it has his own unique challenge. He solved the riddle of the sphinx, he revealed his intelligence. His downfall is as a result of incidents beyond his control, and is rather the result of fate. Answers to Shakespeares Othello Othello begins to doubt Desdemona when she asked Cassio to stay and see the way she would approach Othello, but he went away being ashamed of what he did the previous day. Iago who was with Othello said, Ha! I like not that! and this made Othello have second thoughts about rejecting Cassio and because of his reputations he couldnt be suspicious about his wife and her friend Cassio. Iago builds more doubts when he tells him that the two had been alone together before. When Desdemona leaves with Emilia, Iago preceded convincing Othello of her unfaithfulness. Iago makes Othello to develop jealousness and is not a jealous man by nature. Iago continued to convince Othello that his wife had deceived her father in marrying the Moor. Emilia collaborated with Iago, in collecting the handkerchief that was dropped by Desdemona when she was with Othello but they came convincing Othello that she was using it to wipe Cassios beards. When Othello asked him to produce more evidence, he said that he overheard Cassio mentioning Desdemonas name in a dream and with this he couldnt produce any evidence. Othello lost his sense of humanity as he insulted Desdemona and issued barbaric threats to Cassio. At these scenes it was the lowest point of Othello and on the other hand, it was highest point to Iago who seemed secure in his complete triumph. Difference between Othello Play and the Movie The play is an interpretation of the movie in many ways. It uses the text to develop the story and modernizes characters to appeal to the audience. The audience sees Odin as a basketball player and not a warrior as portrayed in the movie. Racial perception is brought up in a play as there is how uncivilized people are in Africa when Othello describes Africans as being cannibals that eats each other. The theme of jealousy, racial bias and deceitfulness is revealed in both the play and movie. In the play, Rodrigos character is overdramatic, simple minded and dearly loves Desdemona. Though Rodrigos affection seemed adolescent and included jealousy, the movie cannot bring it out. The choice of setting differs in the play and the movie. In the movie the choice of setting in regard to time and geographic location is of a modern era school and surrounding environment portraying modern time. This setting showed the politics involved in high school basketball play. The relationship of womens characters is similar, but the difference comes in the time and setting. The movie uses the difference in the play to emphasize its originality. Conclusion Reputation is important in our society today has it helps everyone in making judgments about others. The hero is more is more likely to be someone who confronts fate in a very personal manner and whose reaction to that encounter serves to illuminate for us our own particular condition. Gilgamesh was a strong and brave thus being qualified as an ideal warrior. He possessed many heroic qualities as powerful, impulsive, sexually aggressive, wanting to conquer the wilderness and protect his people. Othellos reputation played a big role in the outcome of the play and in part caused Desdemonas death and his own. Cassio was a loyal person to be a friend and he always followed orders he was given. Oedipus took every challenge with himself and he had a powerful sense of excellence and self worth. Since he had a high regard for himself, after saving the city when many others could not, people came to him because of his qualities.

Rohypnol Essay example -- essays research papers fc

ROHYPNOL By Jenet   Ã‚  Ã‚  Ã‚  Ã‚   Rohypnol is a drug commonly known as the date rape drug. According to the article â€Å"Drug-Facilitated Date Rape,† by Erica Weir, Rohypnol is not a legal drug in the United States or Canada but it is legal in 62 countries in Europe, Africa, Latin American and the Middle East. It is one of the most commonly used sleeping pill or anti-anxiety drug (Benzodiazepine) in these countries. People can get Rohypnol by prescription. Its main function is to depress the central nervous system. Rohypnol is given t some patients before surgeries because it lowers blood pressure and that reduces bleeding.   Ã‚  Ã‚  Ã‚  Ã‚  A pharmaceutical firm known as Hoffmann-La Roche in the 1970s first developed Rohypnol. It was sold first to Switzerland as a sleeping pill in 1975. It was known to have fewer side effects than barbiturates until some scientists did more studies on the drug and found out that it has many of the same harmful side effects as barbiturates. It was also found to be very dangerous. Abuse of Rohypnol began in the 1970s in Europe at parties. Then in the mid 1990s, high school and college students began abusing it in the U.S. They are using them at dance clubs and raves. U.S. banned Rohypnol in 19997. In an article called â€Å"Rohypnol: Profile of the â€Å"date-rape drug† by Dominick A. Labianca, it was stated that Rohypnol is not sanctioned by the U.S. Food and Drug Administration as a sedative hypnotic drug and is therefore neither produced nor marketed legally in the United States. People could face prison f caught with the drug. It also became illegal for peo ple to bring the drug as travelers into the U.S. for their personal use. Even though U.S. banned the drug, Rohypnol has become widespread throughout the U.S. because people struggle or mail the rug into the country and distribute it.   Ã‚  Ã‚  Ã‚  Ã‚  Rohypnol has many street names. Some are circles, forget me pill, la rocha, Mexican Valium, mind eraser, R-2, roofies, roche, and roaches. This drug is not very expensive and it can be easily found. According to the article called â€Å"Rohypnol, The Date Rape Drug,† by Richard H. Schwartz and Andrea B. Weaver, tablets wholesale for about $ 1.00 and retail for about $ 4.00-$5.00 each.

Drugs are always going to be around but we need to keep on educating people and helping those who need help to quit their addiction. I have heard many abusers of drugs say that they want to quit but they do not know how or where to go to get the help that they need. We need more commercials on TV and more signs in schools so that people know where to go to get help or to remind them that what they are doing is harming them and others greatly.

Automobile Pollution Essay

Automobiles can cause many different kinds of pollution in the environment. Air, health and groundwater pollution are of the most common. The reasons for these problems can be contributed to exhaust systems and light switches that are standard equipment on most cars today. Older and newer cars alike are equipped with a catalytic converter system. Which are supposed to convert hydrocarbons, carbon monoxide and nitrogen oxides into harmless materials emitted from the automobiles engine. According to Robert Harley, when nitrogen oxide from the engines exhaust is â€Å"over- reduced,† a complex chemical reaction ensues. Ammonia gas (NH3) forms in the catalytic converter, which is then emitted from the vehicles tailpipe and released into the air. These ammonia gasses are the cause of haze and may also cause serious health problems. The catalytic converter not only hurts but also helps the environment. Automobiles that have this system on them produce close to 50% less hydrocarbons, carbon monoxide and other gasses. (Converters 1) Which in the long run helps the ozone from depleting even more than it has already. Another problem we face is having vehicles with mercury light switches in the trunk and hood. Mercury is a fluid metallic element that is toxic and can cause various health problems, air and groundwater pollution also. Ford is one of the automobile companies that still use mercury in light switches and certain antilock brake components. The mercury becomes a problem only after vehicles containing it are taken to a junkyard and destroyed. When these vehicles are destroyed the mercury seeps out into the environment and is absorbed into the ground eventually to make its way in to our water supplies. While in the water it can contaminate the fish that in turn we end up eating. Another way the mercury makes it way into the environment is during the process of melting the vehicles in steel furnaces where the mercury vaporizes into the air. (Mercury 1) These particles then can act as a contribution to global warming. Ford has been urged to remove these mercury switches and replace them with a ball bearing switch that costs about 38 cents in all vehicles that are brought in for service, repair, or recall. As of right now Ford has no plans of removing these mercury switches in any of its serviced vehicles. But Ford is currently working with the Alliance of Automobile Manufactures and the Association of International Automobile Manufactures and waste-management directors to eliminate and replace the switches containing mercury in their upcoming vehicles. (Mercury 2) If Ford and other car companies that use mercury switches decide to do this it can eliminate up to 2. 5 tons of mercury from our environment. The problems of automobile pollution mentioned above are only a small portion of the pollution problems we face from automobiles. Many people wonder how these and many other problems that automobiles cause can be fixed, and many have come up with possible solutions. But only a few of the solutions are actually practical. I think we should abolish gas burning engines and start using electrical vehicles. This would eliminate all of the pollution problems. Electric vehicles were once thought to only be a futuristic fantasy, but recently have become a reality. These vehicles are a very environmentally friendly replacement for older gas burning automobiles. Electric vehicles do not require tune-ups or oil changes. These vehicles also don’t emit any ozone depleting gasses and or fumes. Making them a perfect remedy for the already hurting environment. As of right now the idea of an electric car is still in it works and the common gas burning automobile will be around for many more years to come. All we can do is hope that one day that someone will come with a vehicle that is environmentally safe and can help eliminate these problems that automobiles cause today.

Makayla Fails Essays (1353 words) - Americas, Racism, Free Essays

Makayla Fails Essays (1353 words) - Americas, Racism, Free Essays Makayla Fails Dr. Greg Carr Intro to African American Studies February 16, 2016 Framing Question #2: How Did Africans Preserve and Affirm Their Way of Life and Use Their Identities As a Means to Resist Enslavement? Abstract: The question that we are being asked is a powerful one. Africans were basically completely stripped of their identities when they were forced into slavery. But this question is basically saying that they were indeed not completely stripped, so what did they do to keep their identities. What did they do to keep their souls alive? What did they do to keep their stories alive? It is not easy to keep your culture, your religion and your language alive when you are continuously moving from place to place and when you are forced to adapt to different cultures, religions and languages. But despite all of the hardships and struggles, Africans did preserve and affirm their culture as a means to resist enslavement through many different ways. "Culture never dies, it's passed on; that is why it changes" (Carr). Critical Review of Scholarship: Since the beginning of this course, we have engaged in readings that hit almost every aspect of African studies. Something Torn and New: An African Renaissance by Ngugi Wa Thiong'o happens to be one of these readings. This book talks about how the main goal of Europeans was to overpower the African culture by imprinting their culture and ways of living into the souls of the Africans. When discussing this book in class, we basically came up with the conclusion that the Europeans took everything away from the Africans. So not only did they take their freedom, but they took their languages, their memories, and their culture. So when I say the Europeans wanted to "overpower" the African culture, they wanted to completely wipe it out as if it never existed. This book helps you to realize how much the Africans value their language, memories, culture, and their identity as a whole. Another book that really helped me to understand and answer the question asked is The Coming by Daniel Black. This book follows a group of Africans from the moment they are captured in their villages to the moment they are sold in America. In this novel, Daniel Black depicts the characters' journey to the ship, journey across the Atlantic, and complete loss of self. This book was probably the most helpful with answering the framing question because it really puts you in the time and place of slavery. It is like you are actually there and you know everything that is going on. Discussion: The Africans that experienced enslavement went through too much for us to even try to imagine what it was like. As was said before, they were basically forced into a whole new world. To the white man, they were stripped of their name, culture, religion and language. This made the white man (slave owners/master) feel more than powerful. This made them feel like they had full control on the slaves' lives, which they kind of did in a sense. It was almost like they were puppet masters playing with ventriloquist dolls, only this was real life dealing with real people and real situations. In my opinion, Africans were stuck in a very tough situation, but they were smart with the way that they went about it. In order to preserve their lives, identity and their experiences, Enslaved African-Americans created sacred songs and told stories about their experiences. Since enslaved people were not allowed to formally educate themselves, which includes learning how to write down these memories of the past, oral storytelling was the only way to have a connection to Africa. Of everything that was taken and stripped, the mind was the one thing the white slave owners could not erase. As hard as they tried Africans held onto their identities, cultural traditions, and connections through verbal exchange. As was said before, these slaves were smart. They knew that nobody could tell their stories better than them. If they left it up to the white man to tell of their experiences, we might not even know of slavery or the degree of severity to which it was. It was said in the book, The Coming,

Transportation was additionally a public exercise in European states as they hold dominions all above the world. For instance, Australia was industrialized as a British penal dominion as well as Tasmania and supplementary locations. The American dominions were one more point of destination for British convicts (Spierenburg, 1995). Later the American Revolution, England had to halt transporting prisoners to America. As British prisons came to be overcrowded, a colossal number of convicts were assigned to deserted ships†hulks†placed on the stream Thames (Allen Simonsen, 2001). As area penalty was believed a good restraint for offenders, corporal penalty and demise were extremely spread in European countries. As such, torture, mutilation and demise were extremely prominent in Great Britain from the ixteenth to the eighteenth century. With the Enlightenment, a change in penal believed transpired in Europe. In 1764, Cesare Beccaria wrote An Essay on Offenses and Punishments, in that he supported for a profound reformation of penology believed, administration of fairness and punishment. Beccaria (1764) clashed that punishments ought to fit the offense and ought to be precise, quick and severe. In supplement, Beccaria (1764) trusted that regulations should be composed and legal prudence ought to be limited. Jeremy Bentham was one of the managing reformers for British convict law. Bentham supported for a arrangement of graduated punishments to make a system were penalty and offense were equal. Instituted on his believed that humans are hedonistic, the aim of humans is to maximize pleasure as minimizing pain; Bentham trusted that punishments were the best restraint for crime. Bentham was not in favor of the demise penalty but did like the believed of incarceration and area humiliation. John Howard is recognized as one of the main proponents of prison improvements on the past of penology. Howard voyaged extensively all above Europe to examine Jails and prisons. In 1777, he described his indings and his counseled improvements in his State of Prisons. Howard (1777) supported for safeguard and sanitary abilities, inspection and a reformatory regime. As America was a British dominion, settlers lived below the British laws. At this period, punishments were cruel and relied deeply on corporal punishment and demise as incarceration was not an spread exercise. In 1682, Pennsylvania adopted The Outstanding LaW promulgated by English Quaker William Penn. The Outstanding Regulation was quite humane and emphasized on hard labor as extra competent penalty than death. As such, merely premeditated slaughter was ndictable by demise The Outstanding Regulation was in power till it was substituted by the Anglican Program in 1718; an extremely punitive code. The Anglican Program tabulated disparate corporal punishments (e. . mutilation and branding) and thirteen capital offenses Later the American Revolution, the thoughts of the Enlightment obtained momentum. With the thoughts of Beccaria and Bentham and the Statement of Independence, a new penal arrangement was industrialized As such, reformers clashed that Americans had to move away from barbarism and punitive measures of penalty and embrace a extra rational and hum anistic way to ome to be very prominent in Philadelphia as hey industrialized the Area for the Alleviating the Miseries of Area Prisoners in 1787 below the association of Benjamin Rush. The Philadelphia Walnut Road Jail was crafted to imitate the Quaker believed of penitentiary -a locale whereas prisoners might imitate on their offenses and become penitent and therefore experience reformation. Inmates were categorized by their offenses; Weighty offenders were allocated in solitary imprisonment without labor, as supplementary offenders worked across the date Jointly in silence and were confined separately at night. Later the Walnut Road Jail came to be extremely overcrowded, two new prisons were crafted in Pittsburg and Philadelphia, that marked the progress of a penitentiary arrangement established in confinement. In distinct imprisonment, prisoners were grasped in isolation alongside all hobbies grasped in their cells. The Pennsylvania arrangement of distinct imprisonment came into attack due to harsh punishments and prisoners paining mental breakdowns due to isolation. The New York Penitentiary at Auburn was established on the congregate system. Below this arrangement, inmates worked in workshops across the date and hey were retained a portion across the evening time. Elam Lynds, the warden at Auburn, instituted a law of control that included the lockstep and wearing stripped uniforms. Lynds additionally utilized the contract labor arrangement, in that inmates worked for free for confidential employers who endowed raw materials utilized to make products in the penitentiary. By the mid-1800s reformers had come to be disenchanted alongside the penitentiary model. Neither the Pennsylvania arrangement nor the Auburn system attained the anticipated aim of rehabilitation and deterrence. Thus, penitentiaries came to be quickly overcrowded, understaffed, nd brutality was much extended. In 1865, The New York Prison Association provided Enoch Wines and Theodore Dwight the task of surveying prisons nationwide. Wines and Dwight discovered that reformation was not the main aim of countless prisons and that corporal penalty was an spread exercise In 1870, Wines and supplementary penal specialists led an encounter in Cincinnati. From this encounter, a statement of principles was developed. Amid these principles were the demand to use a association of prisoners, indeterminate sentencing and reformation. The ultimate aim of these reformers was the reformation of inmates. The Early reformatory was crafted in Elmira, New York. Zebulon Brockway was appointed superintendent. Brockway was a large advocate of diagnosis and treatment. He emphasized education and training to delight inmates, who were interviewed to comprehend the reasons of their deviance In supplement, Brockway utilized a mark arrangement of association, indeterminate sentencing and parole. Brockway receded in 1900 (Rothman, 1995). The thoughts of Wines, Brockway and supplementary penal reformers considerably contributed to the progress of present American corrections by introducing thoughts uch as inmate association, rehabilitative plans, sentencing, parole and educational plans The early two decades of the twentieth century embodied a drastic change on the communal landscape of America. Industrialization, urbanization and technological and logical advancement revolutionized the American society. At this period, the progressives†upper-class philanthropists†believed that they might resolve most communal setbacks derived from quick urbanization in big rehabilitated across individualized treatment The progressives were deeply affected by the positivist school of criminology Positivists trusted that convict deeds is not a roduct of free will; it is product of biological characteristics, psychological and a little sociological conditions. As such, convicts can be treated (See Lombroso, 1876). The progressives wanted to (1) enhance the conditions of living of little spans whereas criminality was prominent, and (2) reinstate offenders. The progressives pursued governmental deed to enhance the living conditions of the poor as a method to battle crime. Their strategies encompassed larger area health, area housing and education. By the 1920s, the progressives were prosperous on requesting probation, indeterminate sentencing, parole and Juvenile courts. Even though these strategies were counseled at the 1870 Cincinnati encounter, the progressives were instrumental on requesting them across the United States. The medical model of corrections was based on the belief that criminal behavior is caused by social, psychological, or biological deficiencies that require treatment. Based on the progressive movement, the medical model was implemented in the 1930s. One of the main proponents of the medical model was Howard Hill who designed the Norfolk State Prison in Massachusetts in 1927. Gill staffed his prison with educators, psychologists and ocial workers to provide individualized treatment to inmates. In 1929, Congress authorized the new Federal Bureau of Prisons under the leadership of Stanford Bates, to develop institutions with treatment as the main goal. Bates was a strong advocate of the medical model. The 1950s is known as the era of treatment in American Corrections. Punishment was perceived as an obsolete way to deal with offenders and treatment took a central role in penology. To this extent, prison became mental health institutions were inmates were continuously tested for their readiness to reenter society. After World War II, psychiatry was used as a tool to rehabilitate offenders. As such, group counseling, behavior modification techniques, psychotherapy and individual counseling were common ways to treat inmates. Marylands Patuxent Institution was one of the best examples of a prison built according to the principles of the medical model. During the 1960s and 1970s, the American society experienced many changes due in part to the civil rights movement, the war on poverty and the Warren Court. Contrary to the medical model, the community corrections model advocated for the reintegration of the offender into society. Proponents of the community model proposed that psychological treatment should be substituted for vocational and educational programs that helped inmates to become successful citizens. Due to rising crime rates, in the mid-1970s, critics of the rehabilitation model attacked indeterminate sentencing and parole urging release not to be linked to treatment. Proponents of increased crime control called for longer sentences particularly for habitual and violent offenders. Robert Martinson surveyed 231 treatment plans in the United States and, in 1974, he published a report shouted What works? Inquiries and Answers on Prison Reform. In his report, Martinson finished that, except for insufficient plans, rehabilitation did not have each affirmative result on recidivism. The Martinson report was utilized by officials to apply a get tough philosophy on penology. As such, in the 1980s and 1990s, the new crime ideal supported for the use of incarceration and severe supervisions well as (and yet are) at that time. References Foster, B. (2006).

Human Resource Management of organization in Commonwealth Bank of Assignment

Human Resource Management of organization in Commonwealth Bank of Australia - Assignment Example Hereby, the paper aims at studying the overall business strategies considered by CBA for its long run improvements in order to fulfill the vision to serve customers with the best service in banking and to be reputed as one of the finest banking organizations in the Australian history. Strategies From a generalized point of view, it can be noted that the considered strategies of CBA focus largely on the primary functioning departments such as ‘customer service department’, ‘business banking dimension’ and ‘technology & operational excellence department’ which in turn can be learnt to amplify trust as well as team spirit within the employees. The strategic planning for the customer service states that it is considered in order to build a good relationship with the customers by serving them with best facilities as compared to other banks. The strategies considered under customer service mostly concentrate on redecorating the existing sales and serv ices program with innovative benefits and features for the customers (Commonwealth Bank, 2006). CBA can also be identified to take certain measures to increase its customer base facilitating them with easy processing system. Under business banking, CBA also attempted to introduce CommSee and ComBiz to enhance its functioning with informational technology so that customers avail the services smoothly. CBA also introduced the business banking dimension in alliance with other institutions to facilitate the customers with tailored services. The strategies planned for developing the technology and operational excellence are by providing the virtues of Information Technology with group-wide leadership, applying smarter sourcing and simultaneously improving the lean process with innovative ideas. The organization also believes that to have an effective outcome from the strategies, employees need to have trust and team sprit among themselves for which CBA always considers new thoughts to bu ild good relationship and collaboration within the workforce as well as with the customers. Furthermore, CBA frequently focuses on the process and the methods to develop their employees’ productivity, customer base along with their functioning. CBA also took certain measures to involve with the community by considering the safety for the people (Commonwealth Bank, 2006). CBA consequently tends to consider innovative strategies in order to become the best banking organization in the Australian history. For its profitable growth, CBA also planned certain strategies maintaining a good relationship with others along with the growth of agenda, simultaneously developing its traditional market by investing or expanding its target market. CBA also introduced a new strategy of insurance policy as CommInsure which facilitated the customers with life insurance policies. This particular strategy can be further observed as the organizational measure taken towards developing the services a nd reform the process so as to obtain better efficiency (Commonwealth Bank, 2006). Illustrations It is worth mentioning in this context that incorporating the aforementioned a few innovative customer-centric strategies, CBA was able to achieve the second position in the national banking sector under Australian Security Exchange. Furthermore, the growth of CBA also indicates the level of services owing to which, the organization has been able to satisfy the customers’

PATTERN OF KNOWING AND NURSING SCIENCE Assignment

PATTERN OF KNOWING AND NURSING SCIENCE - Assignment Example Aesthetic knowing is â€Å"knowing that connects with deep meanings of a situation and calls forth inner creative resources that transform experience† (Hood, 2014, p.116). It is considered the knowing of feelings. This is where you build a sense of trust with family members and the patient. For examples, last week I was assigned a patient whose family members, I was told, would be difficult. I went into the room and explained everything that was going to be done to the patient. I also involved them in the care and educated them about the patient’s situation while interacting with them and giving them a sense of belonging so that I could gain their trust. There is also personal knowing, which I believe comes hand in hand with the aesthetic part of knowing. Once that connection is established, personal knowledge will come easily— the building of a patient-nurse relationship, the formation of trust, that solid foundation that is truly essential in accomplishing the desired outcomes. According to Hood (2014, p. 117), â€Å"The individual must be open to experience and intuitive feelings, be honest with their self, and make efforts to acknowledge the response of others...† Sometime ill people simply need someone to listen and some affection. For example, I had a very anxious patient to take care of and her heart rate rose to 130. I went into her room, sat and talked to her for 30 minutes. After we laughed and I gave her a hug, she was fine. With this being said understanding and appreciating the ways of knowing develops and enhances your nursing practices, making you a better nurse. We are able to see different things from different points of view. Using the ways of knowing in practice and delivery of care can change a lot of lives and increase customer service for our patients. According to Hood (2014, p. 117), â€Å"The individual must be open to experience and intuitive feelings, be honest with self, and make efforts to acknowledge the response of

Cults and the impact on Family in an Social Psychology approach Research Paper

Cults and the impact on Family in an Social Psychology approach - Research Paper Example New religious movements may also have a basis in ethics, theology, philosophy, or religion to some extent. Usually, but not always, new religious movements are part and parcel of Christianity. Groups such as the Branch Davidian cult is one example. Cults need not be destructive in nature, however. Many people who study social psychology have adopted the term â€Å"new religious movement† as a way of describing cults in neutral language. New religious movements may be communitarian, or they may be specifically spiritual or religious in nature. Usually what separates cults from other religious movements in society is their unique ability to isolate people from other social networks. This is where social psychology plays a crucial role. Since the family is deeply intertwined with society, the psychology of such groups affects one’s psyche. New religious movements are part of the dominant culture. Usually, however, new religious movements are on the fringe of society. There is much controversy over what constitutes a â€Å"new† religious movement. Some people use certain dates as benchmarks for saying a religion is new—for example, a religious movement that has occurred within the last 20 years or so. People generally also have come to realize that what constitutes the stipulation of being distinct from other religions as difficult to empirically analyze. Generally, however, the distinction between new religious movements and established religions is that although the religious movement may be seen as part of an existing faith tradition, it meets with some type of clash within the religion for its varying belief systems—and thus is not an accepted branch of that religion. This research question is important because the family structure as it relates to social psychology, is very fragile in this day and age. The way children are raised today relates much to the way the community is structured, who is involved

Economics Question Essay Example | Topics and Well Written Essays - 500 words

Economics Question - Essay Example A market system lets the market decide what is produced. A lot of different price points—effectively the invisible hand—decide where resources go and what prices should be. Production is decided by supply and demand. In a socialist economy the government or a committee decides they would like more butter or more shoes produced in the current year and choose a quantity for production that they believe will be sufficient (it rarely is—or it is far too much). Describe the theoretical mechanism in which consumers are sovereign, who consumers really decide what goods they want and how they demonstrate those decisions and desires. Is there a contradiction between the statement that businesses decide what is produced and the idea that consumers have sovereignty? Consumers are sovereign in so far as in a market economy their demand decides what products are produced. Businesses decide what to produce based on their reading of consumer demand. Businesses fail when they have not properly estimated the demand for their product. Consumers are sovereign. National defence – this is too important to outsource to the market; Some health care such as Medicare and Medicade. Maintaining national parks. Taking taxes.

Medicare Value Based Purchasing Program Research Paper

Medicare Value Based Purchasing Program - Research Paper Example The implementation of separate value based purchasing programs for each of the different Medicare providers requires more than just trumpeting the program. The program has different payment levels and efficiency measuring strategies for hospitals, physicians and other practitioners, home health agencies, ESRD providers and facilities, and skilled nursing facilities. (Reichard 2009). The Policy: The Medicare Value based purchasing programs have been formulated in an effort to facilitate the transformation of the Medicare system from a passive payer of claims to an active purchaser of care. The operational infrastructure of RHQDAPU as established by the CMS has been used as a base for the development of Medicare Value based purchasing programs which includes the following provisions: i. As specified by the President’s FY2006 and FY2007 budgets, the value based purchasing programs are budget neutral and are formulated in accordance with the policy recommendations of Institute of Medicine (IOM) and Medicare Payment Advisory Commission (MedPAC). ii. The existing Medicare performance measurements and reporting infrastructure together with RHQDAPU components have been used as a foundation for the structure of Value Based Purchasing Programs. iii. ... In accordance with the provisions of Patient Protection and Affordable Car Act of 2010, the data collected in the initial year would be utilized in informing the concerned medical individuals about their incentive payments. v. The implementation and coordination of VBP program would be undertaken by CMS, which will also monitor the effectiveness of the program through consensus processes such as Hospital Quality Alliance (HQA), National Quality Forum (NQF), and the Joint Commission on Accreditation of Healthcare Organizations (JCAHO). vi. The reporting requirements specified in Division B, Title 1, Section 109 of Tax Relief and Healthcare Act will be utilized by VBP programs for the measurement of performance and the calculation of incentive payments. vii. The VBP programs will undertake the responsibility of eliminating existing disparities in the health care system. The enforcement of the Value based purchasing programs would not be undertaken without the consent of the concerned m edical personnel. viii. A withholding up to 2% of total payments pertaining to specific Medicare providers would be utilized in the evaluation of the incentive pool. All funds collected under the value based purchasing programs will be offered as incentive payments to the eligible participants will not be changed over time. (U.S. Department of Health and Human Services 2007). Models of VPB Programs: The value based purchasing programs are composed of three models which are listed as follows: Model 1: Single Large Purchaser: This involves a large active Medicare supplier which is working collaboratively with other suppliers. If reward incentives are targeted at these individuals then inevitably the overall performance of the health care system as a whole will

Echo Planar Imaging, or EPI, Fast Imaging Techniques (MRI) Essay

Echo Planar Imaging, or EPI, Fast Imaging Techniques (MRI) - Essay Example EPI is fast because it uses single excitation of a slice followed by the continuous readout through the k-space using GRE pulse sequence (Delbeke, Martin, Patton and Sandler, 2002). After the RF excitation MR imaging mostly depends upon the formation of echo at some point. Spin echo (SE) sequences are the most former MR sequences (in fact earlier to imaging) (Westbrook, 2009). EPI is called blip because between echoes phase blip causes change in Ky and a new line is sampled. In EPI each gradient refocused echo contributes one line in k-space. The positive and negative read gradients change the direction in which the line is read. In contemporary MR system that are capable of EPI, the fast varying magnetic field linked with the shifting of the magnetic field gradients is capable to produce currents within tissue, which may exceed the nerve depolarization threshold and cause peripheral nerve stimulation (PNS). However, the chance of cardiac muscle stimulation also exists, as a result p resenting an artifact (Delbeke, Martin, Patton and Sandler, 2002). From the research on animals it can be suggested that stimulation of respiratory system takes place at exposure levels of the order of 3 times that necessary for PNS, while cardiac stimulation requires 80 times the PNS threshold. The probability of occurring PNS is mostly in EPI. Particularly one has to be cautious of 2 situations: (a) Whilst sloping slices are utilized and it is probable to have a greater slew rate through adding the contributions from two or three sets of gradient coils. (b) For coronal or segittal EPI where the possible current loops in the torso are greatest when the read gradient is in the head-tool direction. In general, dB/dt is monitored through the scanner and lead to the likelihood of stimulation (Delbeke, Martin, Patton and Sandler, 2002). Spin Echo EPI The most commonly used sequence is known as spin echo. It is characterized by the initial application of a radio-frequency pulse of 90 deg rees, followed by one more in front of 180 degrees, then double the time between these two pulses a signal or echo from stimulated tissue is successively applied with several pulse sequences of 90 and 180 degrees, each of which produces an echo which will form the radio wave which provides molecular information. In carefully constructed sequences extra slices are excited while waiting for T1 recovery, so one phase encoding step is acquired for several slices during TR (Weishaupt, Koechli and Marincek, 2008). In a spin echo sequence, the phase encoding changes amplitude every TR. This is to give each echo the correct 'kick' to place it on the right line. You can think of it like a soccer ball tied to a piece of elastic. You need a hefty kick to move it to the outer edges of k-space (large phase encoding gradient), and a little kick for a line closer to the center (small phase encoding gradient). The spins always return to the centre line (i.e. the elastic in our analogy) because you are re-exciting the spins each TR in a spin echo sequence (Bankman, 2008). (Weishaupt, Koechli and Marincek, 2008). Figure shows spin echo pulse diagram, with the sampling of k –space. Reducing the time of the Image For acquiring an image time required is based on the following relation. Tacq = Nacq X Nv X TR Where, Nacq = acquisition number, Ny = Number of steps for phase encoding, and TR= Time period for repetition. Hence in order to reduce time of

The Media’s Framing of the Israeli-Palestinian Conflict Essay Example for Free

The Media’s Framing of the Israeli-Palestinian Conflict Essay It’s funny, but even the Wikipedia (let’s generously call it the â€Å"encyclopedia† of today), notes that their Israeli-Palestinian conflict article might contain a little something known as â€Å"recentism,† which, to roughly paraphrase Wikipedia, can be defined as the tendency to edit or inflate a current issue without thought to a broader historical perspective, simply because the issue or event happens to be blasting through homes and children alike and the media is playing the same gory scene over and over while vendors pump up their magazine sales by shoving suffering, impoverished, and war-torn families down unwitting consumer’s throats. But that’s the money maker. The mass media may hide things and they may create fallacies like â€Å"Wag the Dog† from time to time, but the media is essentially about money. If, for example, the President seems to want a more homey-let’s-not-worry-about-things kind of attitude, then the media will portray that attitude because, and this is the kicker, even though they are protected by the First Amendment and the whole â€Å"freedom of speech† thing, they have to write the perspective that sells. Now, recentism may sell when the war was happening five years ago, but as the conflicts rage on, the public agenda isn’t to promote war—at all. If the President was sitting in his nice big white house and promoting the war while American soldiers pile up by the body bag, then the President isn’t doing very good at his job. Very soon, if all people saw was mass conflict, death, and horrible destruction, someone would have a gun to the white house to get a better leader on that golden throne. However, if a â€Å"little† battle leaks out from time to time, and the media as a whole is on the story with the same, homogenous mono-headlines, then the public will see that there was an uprising, yes. But, if that uprising isn’t mentioned again, or it blows away like so many things after a few weeks of nothing new being reported, the public will be lulled into thinking that everything is okay and that it was just a simple little uprising. No big deal. Sure some American soldiers were sent home with flags on their caskets, but they died heroes. Purple hearts, parades, and fancy color-guard funerals. That’s what the people see. Even though the Israeli-Palestinian conflict has been raging for, what ladies and gentlemen, more than fifty (more like hundreds) years, is the American public even aware that the peoples in those warring nations have been at war, bombs in the streets, children murdered, every day for as long as most of this generation has been alive? Nope. For the most part, the American public is kept in the dark. So dark that the current issue in Iraq (when was the last time the â€Å"war on terror† actually scared the public?) has even lost its juice. Terror is just a word now. Not scary, not vengeful. Just another word that has been so drilled into the minds of the public that â€Å"raising the terror alert† does no more for people than if the pollen count went into the red zone. People are so in the dark that when nine soldiers died just days ago (Londono) that most people didn’t even raise an eyebrow, because what’s the big deal with losing nine measly soldiers if the country is over on foreign land playing the philanthropic hand with democracy? Big numbers are the only things that count. Nine soldiers dead in what seems like six years (since 9/11) is nearly negligible. This is tangenting now, strictly for reasons of importance, but only Alertnet. com tallies up the body count at 3,170 US soldiers dead since the war began in the same article, (well, in the middle third of the story but at least it was mentioned) as the report on the nine dead soldiers. Now that’s a number worth hearing. But how many news reports call that fairly alarmingly number up? Not many. Actually, most striking was the amount of anti-war sites that call up the numbers, some counting American casualties as high as 23,000 (Griffis) since the war officially began in 2003. Now that number would catch some eyebrows. Freak people out, get them burning bras for peace, not war. But the President doesn’t want that. The government certainly doesn’t want that. And perhaps this is why the media keeps the death stories on the hush-hush. Frame it in a way that makes the country feel safer as a whole. Only a few soldiers are killed at a time, so the tally seems insignificant in the broader scheme of things. And thus the public agenda is to get Americans back to their daily lives, where war doesn’t exist and heiresses get caught too often without their underwear as the paparazzi catch them at some new celebrity’s bar. But that’s just a recent example of how the media skews things to keep the public agenda on the right track, lest things derail. And by golly it was a tangent of importance because if a war so dear to the hearts of Americans is lost in the media hoopla, how does a war like the Israeli-Palestinian conflict, which is a vastly different scale, even stand a chance at global comprehension? Well, it doesn’t. And, it is perhaps the most notable war of any ever fought since times too ancient to remember. Data Collection. The data collected for this report has been a combination of news reports and Wikipedia articles. The news reports were chosen because they are exactly what the public is able to view on a daily basis and are taken with complete seriousness to report the truth of the news (sounded like a joke, didn’t it? ). As a whole, the news reports can be compared and contrasted for similar headlines, feature points, pictures, and opinionated slants. For the most part, articles have been used from the Vanderbilt Television News Archive, and it is interesting to note that the most current evening news report is dated 12/06/2006. This could be an error on Vanderbilt’s part; perhaps they haven’t updated their news archive since then, but it is much more likely that Vanderbilt has the most current news out there, which actually serves as a perfect example of how the media has prioritized this conflict in the news. No news, for Americans, can be construed as good news, even if the conflict rages on. Wikipedia articles were also reviewed, though not for the charts in the analysis of the data collection, because the Wikipedia has undeniably become something akin to the Encyclopedia Britannica of earlier years. While the articles are not purely scholarly or always written by PHD subject enthusiasts, the articles are highly peer-monitored and perhaps more free in what they are able to speak out about than a regular news article with advertisers to please and bosses with the weight of the powers that be on their shoulders. Finally, a totally independent site, dubbed â€Å"Angel for Israel,† has been reviewed because it has a catalogue of news articles chosen from recent years in an attempt to showcase the very issue of media framing and public agenda. The site even goes deeper to debunk the myths, expose the media propaganda, and review common misconceptions about the Israeli-Palestinian conflict. While not everything on this site can be truly confirmed as to authoritative authenticity, the news articles are complete, unedited and link back to their original news source. So, a wide cross section has been chosen for data collection so that a slant of some sort can be gathered, tethered, and plumped for show. And, for editorial purposes, the full headlines and dates used for the purposes of the charts in the Analysis are presented as raw data in the Appendix. Analysis. It’s always fun to chart and show, so the data collected has been put through the supercomputer to explain how the media portrays highly sensitive (i. e. death, war, terror) news as a homogenous chunk of untitillating information to the uninformed and unconcerned public. So let’s delve. First, it’s easy to simply compare and contrast news headlines for homogenous information to depict and conclusively prove framing of the public agenda by the media. Looking at the Angel for Israel 2005 News Archive, there are 21 news articles with similar headlines. The first ten headlines for comparison are: Female Suicide Bomber Explodes at Erez Crossing, Killing Four Israelis Hamas Woman Bomber Kills Israelis Suicide Attack on Jerusalem Bus Hamas Threatens Soldier Kidnaps Suicide Bomber Kills 10 Israelis. Prisoners Freed as Bomb Kills 10 in Israel Suicide Bomber Hits Jerusalem Bus Suicide Bomber Kills 8 in Jerusalem Terrorists Infiltrate Erez Industrial Area, Killing Israeli Soldier Couple Killed in their Car Between Hebron and Beersheba, Terrorism Suspected Now, looking at the headlines, it can be said that the reports are straight and as to the point as they could be when it came down to writing the headline for the news. The problem is that the headlines are so similar that it can have a deadening effect on the public agenda. Seeing a word over and over, the word no longer has the same meaning that it did the first time it was seen. For example, the word â€Å"suicide† is used five times out of ten headlines, all having taken place between a month or so period. The word â€Å"kills† (and forms of it like â€Å"killing†) is used in the same news headlines seven times out of ten. If these were the only headlines, which they might very well be, from this period in January and February 2004, the chance is that the public will read one and miss the others because though they all discuss different events, they read as nearly the same. So, nine stories would be missed simply because of a redundancy factor that happens, for reasons probably planned and perfectly executed. That same public then believes that the violence isn’t so wide-spread because of the same framing phenomena that occurs when no news is reported. If the headlines read a bit differently then these ten conflicts and acts of terror could be read and understood and ten separate issues of violence and horror. But, as they are, they lose their potential for a reader to feel any sort of fear because of their homogenous nature. Moreover, the repetitive nature of the headlines does more than just numb a reader to their very existence and meaning, reading or hearing the same word over and over loses much more than that. Words, by their very reality, have inherent meanings to viewers in regards to reaction and understanding. For example, when the President first coined the phrase â€Å"war on terror,† the American public had the appropriate reaction and felt the same need for vengeance and duty as the words permit. Now, six years later, hearing the â€Å"war on terror† has a completely opposite effect on the public. It has become a common, annoying phrase even, because it has lost all meaning both symbolically and literally. Vengeance has not been achieved, no retribution for the â€Å"war on terror† has been sought. And symbolically, no ballads have been created to promote any sort of American pride or glory. Basically, the only thing come of this phrase is that it is said so often it means nothing. And now, any time the public reads the words â€Å"war on terror† they unconsciously close their eyes or ears to any further understanding because it means nothing anymore. Clever, the mass media, for using the â€Å"war on terror† in such a manner that it becomes nothing more important than the rising gas prices during the hot summer months. Moreover, one thing that stands out right away is the use of certain words that prevail in most all if the articles. So, let’s take a deeper look at the most prevalent words and how often they are used overall. Out of those same ten headlines, the word â€Å"kills† and â€Å"suicide† are the most influential and hold the most power over a reader, but a few other words are used often enough to draw attention for analysis. These are the words: Kills (killing, killed) –used 7 times Suicide –used 5 times Explodes –used 1 time Attack –used 1 time Threatens –used 1 time Kidnaps –used 1 time Freed –used 1 time Hits –used 7 times Terrorists (terrorism) –used 2 times Infiltrate –used 1 time On a side note, proper website and content search engine optimization relies on the ability of a writer to get the meaning of something across while also adding in the proper words to also get the attention, subliminally, of that reader or search engine. The key is that with 200 words of text, 8% of that text must be used for each main keyword. This means that at least 16 words out of 200 words must be utilized for one main keyword. For example, if an article were written on the Israeli-Palestinian conflict, and the keyword that article was hoping to subliminally infiltrate into the reader were â€Å"suicide,† then â€Å"suicide† would have to appear 16 times in 200 words of text. The exact same formula is used in reporting and even broadcast media like advertising. Ever hear of the Energizer Bunny? Or that truly annoying â€Å"Head On† commercial promoting direct application of a lube-like substance for migraines? The reason commercials do well with the public is that even though they may lose all meaning simply from being repeated so often, repetition for products is the only thing that really sinks in enough for that public to remember what product they wanted when they get to Wal-Mart. With that said, it is easy to see why some words, the words with seemingly the most power, are used more often than others, especially in the print media. And, in an interesting phenomena known as media framing, it actually tends to have the opposite effect on readers. People don’t read the news in the same way that they view a commercial. A different part of the brain is used, and a more mechanical side of that person takes note of different things when viewing a commercial versus reading a news article, which is something having much to do with emotion. Emotion in advertising is a draw to get a listener or reader to want, no need, that product. Repetition in this case hinges on the emotion that product is able promote, to get inside the heart of the person. Because, more often than not, people buy something because they want it, not because they need it. However, emotion is generally not a thing possessed by headlines, but headlines are usually crafted with some attention getter in mind. After all, if they weren’t written for a person to be interested enough to read, then they wouldn’t get read at all. And, looking at the same ten headlines, it can almost be said that they were cleverly crafted to not get read at all, especially because of their exclusively homogenous theme running throughout. Now, to see if this theory really stands on its feet, let’s take a look at the top ten headlines from the 1997-1998 Angel for Israel News Archive. These are the ten headlines: Unilateral Measures Taken by the Palestinian Authority in Violation of Oslo Palestinian Authority’s Failure to Quell the Riots in Hebron Violates the Accord PLO’s Hiring of 150 Terrorists as Policemen is Blatant Violation of Oslo Palestinian Authority Failed to Fulfill its Commitment Under the Hebron Accord 18 Killed in Jerusalem Attack Palestinian Incitement to Violence Since Oslo A Four-Year Compendium Pronouncements by Muslim Religious Leaders Defending Suicide Attacks Palestinian Security Commitments Palestinian Anti-Semitism Prison or Hotel? PLO’s Open Door â€Å"Jail† Sheltered Jerusalem Bombers from Israel. Now, one thing in looking at these headlines is that although the conflict can be said to undeniably the same in regards to death, suicide bombers, and the level of terrorism, these articles have very little to do with reporting that issue. Instead, they promote the Palestinian government and its ability to â€Å"quell† the violence and attacks. And, this time when a bit of violence is mentioned, it stands out enough that people can read it, then read the next news about that violence being stamped out and come to an understanding that their government is doing everything in its power to take control of the country and make things safe. Moreover, each instance of violence is discussed and â€Å"defended† or â€Å"sheltered. † While these are probably the most insane and contradictory headlines of the year, they actually show a bit about the society of the time and what the public agenda was. Cleary, this was a time of being unable to admit that terrorism was a real thing, a real threat to communities even though they had been fighting a war for some hundred years. The same headlines were probably used when the United States first saw terrorist attacks, before the events of 9/11. Terrorism wasn’t even a word, or a word often used in the common vernacular, before the real attacks began, because the media didn’t want the readership to feel threaten. This way, by keeping such terms on the down low, or by making them look like flukes, easily put down by the government, the media could control the public agenda and make them believe that such things were easily enough thwarted that there was no need to worry. In an effort for fairness and uniformity, these same ten headlines will now be looked over for words of repetition. These are the main words: Authority –used 3 times Violation –used 2 times Quell –used 1 time. Commitments –used 2 times Killed –used 1 time Terror –used 1 time Attack –used 2 times Violence –used 1 time Suicide –used 1 time Defending –used 1 time Sheltered –used 1 time From these keywords, it is easy to conclude that the public agenda was much different for the mass media than it was in 2004. These years (1997-1998) were much more about promoting the government and putting down the terrorism enough that it didn’t even seem to exist. And in instances where they could do nothing but report it, the same headlines â€Å"quell† it or â€Å"defend† the terrorism to make the public believe that the situation is much different than it is. But that’s the purpose of framing in the media. And, from these examples, they have their job down. Summary and Conclusion. Well, the data doesn’t lie. Whoever controls the media (and someone does, be sure of that) controls the public agenda and what is dolled out as information as well as the why, when, and how of things. The simple fact is this: the news is not reliable. For the real numbers, perhaps only the fan sites tell the truth of things because freedom of speech still exists on the internet, if no where else. Now, not all sites and sources online are to be trusted and blah, blah, blah, but is the published report or the prime time special with Barbara Walters to be trusted either? Who can be trusted when it comes to the cold, hard, nitty-gritty truth? Well, the one thing that the American public can trust is themselves (for those willing to listen, at least). Freedom of speech was granted for the media to tell the tales they wanted to tell when the aristocracy got a little grabby, but times have changed and so has the media. Now, the only real media is the media and press that makes the most money. Without money, even small town newspapers and stations fail, and they might be the only source of news for miles around. One would think that readership would boost things a bit, but the real money is handed out by advertisers who want certain things printed and certain things revealed as deemed fit by the big guys in charge of the nation. And those big guys only share information as framed specifically for the public agenda. It’s their job. The sad truth is that the dog is wagging its tail here, vigorously, but the American public doesn’t even know what that means. Appendix.

Exploring The Chemistry Of Adhesives Chemistry Essay

Exploring The Chemistry Of Adhesives Chemistry Essay An adhesive is a substance that sticks to the surface of an object such that two surfaces become bonded. A typical home improvement store carries many different adhesives for many different applications..The interaction of molecules is known as intermolecular bonding, or secondary bonding. Primary bonding, also known as intramolecular bonding, is the interaction of atoms within a molecule and includes covalent and polar covalent bonding. Secondary bonding includes dipole-dipole bonding (the interaction of molecules that have a permanent net dipole moment) and hydrogen bonding (an interaction that occurs when a hydrogen atom is bonded to an N, O, or F atom in a molecule). Adhesives cure when the small resin molecules join together to form extremely large molecules known as polymers. For example, one of Some adhesives, such as this wood adhesive, are used only with specific substrates because of the cure time needed to allow for good bonding. The simplest polymer is polyethylene. The mer (basic building block of the polymer) is ethylene, H2 C=CH2. The addition of an initiator (R) causes the formation of the radical RCH2 CH2 . A radical is a species that has an unpaired electron and is very reactive because it seeks the source of electrons. This radical will attach the ethylene mer (the double bond in ethylene is rich in electrons) to start a chain reaction that continues until very large polymer molecules form. This and other forms of polymerization processes are the basis for the formulation of polymers. This process is known as curing when dealing with adhesives. Two criteria must be met in order for a molecule to possess a permanent net dipole moment: (1) an unequal sharing of electrons within the molecule such that one or more intramolecular bonds has a partial positive end and a partial negative end, and (2) a geometry such that the vector sum of the individual dipole moments does not equal zero. The ability of an atom within a molecule to attract electrons is known as electronegativity, a concept proposed by Linus Pauling who established a table of relative electronegativities. In Paulings table, fluorine is the most electronegative element and is given the value of 4.0. The greater the difference in electronegativity between two atoms within a molecule, the larger is the dipole moment in that bond. Because the bond between two atoms having unequal electronegativities has a partial positive end and a partial negative end, it is said to be a polar bond. If the geometry of the molecule is such that the vector sum of all of the dipole moments does not equal zero, then the molecule is polar. The electronegativities for carbon and oxygen are 2.5 and 3.5, respectively; therefore, the carbon-oxygen bond is a polar bond. A carbon dioxide molecule has two carbon-oxygen bonds; however, its geometry is such that the vector sum of the two dipole moments equals zero, and thus carbon dioxide is a nonpolar molecule. The electronegativity of hydrogen is 2.1, thus a hydrogen-oxygen bond would be polar. A water molecule has two hydrogen-oxygen bonds. The geometry of a water molecule (the H-O-H bond angle is 104.5 °) is nonsymmetrical, hence the vector sum of the dipole moments is not equal to zero and water is a polar molecule. Polar molecules will attract other polar molecules because of their net dipole moments. Water molecules, however, have an additional attraction for one another, based on hydrogen bonding. This attraction is so strong that, although water is a small molecule and small molecules tend to be gases, water is a liquid at room temperature. This aspect of the chemistry of water demonstrates that hydrogen bonding is a relatively strong force that can hold molecules together. Two surfaces there must be several types of interaction between the adhesive and both substrates. The first type of interaction is that the adhesive must wet the substrate, that the adhesive must spread itself out into a film that covers the substrate surface. In order for this to happen, the adhesive must have a low enough viscosity so that it will flow. Viscosity is the resistance of a liquid to flow. Water has a low viscosity whereas honey has a high viscosity. Because viscosity is temperature dependent, the application of a cold adhesive to a substrate, or the application of an adhesive to a cold substrate, may result in poor wetting. Another factor that affects wetting is the relative strengths of cohesive forces, and those of adhesive forces. If the cohesive forces among adhesive molecules are weaker than the adhesive forces between the adhesive molecules and the substrate surface, then the adhesive molecules will spread out over the substrate and wet its surface. An adhesive t hat has a relatively low viscosity and is able to wet the substrate surface will flow into any tiny cracks or pores on the substrate surface. Mechanical bonding is one of several ways that an adhesive bonds substrates. All surfaces, except those that are highly polished, have pores. If the adhesive flows into these pores and then polymerizes, a mechanical bond is formed. The interactions of adhesive molecules with substrates are so critical, it makes sense that some adhesives would be more appropriate for a specific substrate than others. Adhesives are designed for specific applications. For example, adhesives known as super glues (cyanoacrylates) are useful around the home in the bonding of common substrates (e.g., dishes, toys, etc.), which can take place in a matter of seconds. Cyanocrylates tend to be brittle thus they are vulnerable to impact and dramatic changes in temperature. To reduce these shortcomings, small amounts of finely ground rubber has been used as filler. The rubber introduces flexibility thus reducing brittleness. In addition, cyanocrylates are attacked by polar solvents. Polar solvents will weaken cured cyanocrylate bonds over time. Therefore, applications involving water, alcohols, or other polar solvents should be avoided. Cyanoacrylates are not appropriate for the bonding of the steel parts of an automobile, because of the environments that the car will be exposed to. Those environments include such things as rain, variations in temperature, exposure to solvents (such as gasoline, oil, and windshield washer solution), ozone, acid rain, salt spray, and ultraviolet light from the Sun. Another example of a special adhesive would be the one used to attach a new rearview mirror in an automobile. Because the cured adhesive in this case will be exposed to wide variations in temperature and to an extremely large amount of ultraviolet light from the Sun for prolonged periods of time, an adhesive formulated specifically for these conditions should be used. Finally, the strength and permanence of the bond formed between adhesive and substrate must be considered when one is selecting an adhesive. Most of the time it is desirable to have maximum strength and permanence; the very common Post-it note, however, is a counterexample. Its adhesive is neither strong nor permanent. Lists of some common types of adhesives and their uses. Because of the different possible substrates and combinations of substrates, and because adhesives are subject to such a range of environmental conditions, it is no wonder that there are so many types of adhesives on the market. However, if one has some knowledge of how adhesives bond to substrates and the types of substrates being bonded, the task of selecting adhesives will not be overwhelming. TYPES OF ADHESIVE NATURAL ADHESIVE Animal glue Casein glue Blood albumen glue Starch and dextrin Natural gums SYNTHETIC ADHESIVE Contact cements Structural adhesives Hot-melt adhesives Pressure-sensitive adhesives Ultraviolet-cured adhesives NATURAL ADHESIVE: Natural adhesives are primarily of animal or vegetable origin. Though the demand for natural products has declined since the mid-20th century, certain of them continue to be used with wood and paper products, particularly in corrugated board, envelopes, bottle labels, book bindings, cartons, furniture, and laminated film and foils. In addition, owing to various environmental regulations, natural adhesives derived from renewable resources are receiving renewed attention. ANIMAL GLUE The term animal glue usually is confined to glues prepared from mammalian collagen, the principal protein constituent of skin, bone, and muscle. When treated with acids, alkalies, or hot water, the normally insoluble collagen slowly becomes soluble. If the original protein is pure and the conversion process is mild, the high-molecular-weight product is called gelatin and may be used for food or photographic products. The lower-molecular-weight material produced by more vigorous processing is normally less pure and darker in colour and is called animal glue. CASEIN GLUE This product is made by dissolving casein, a protein obtained from milk, in an aqueous alkaline solvent. The degree and type of alkali influences product behaviour. In wood bonding, casein glues generally are superior to true animal glues in moisture resistance and aging characteristics. Casein also is used to improve the adhering characteristics of paints and coatings. BLOOD ALBUMEN GLUE Glue of this type is made from serum albumen, a blood component obtainable from either fresh animal blood or dried soluble blood powder to which water has been added. Addition of alkali to albumen-water mixtures improves adhesive properties. A considerable quantity of glue products from blood is used in the plywood industry. STARCH AND DEXTRIN Starch and dextrin are extracted from corn, wheat, potatoes, or rice. They constitute the principal types of vegetable adhesives, which are soluble or dispersible in water and are obtained from plant sources throughout the world. Starch and dextrin glues are used in corrugated board and packaging and as a wallpaper adhesive. NATURAL GUMS Substances known as natural gums, which are extracted from their natural sources, also are used as adhesives. Agar, a marine-plant colloid is extracted by hot water and subsequently frozen for purification. Algin is obtained by digesting seaweed in alkali and precipitating either the calcium salt or alginic acid. Gum arabic is harvested from acacia trees that are artificially wounded to cause the gum to exude. Another exudate is natural rubber latex, which is harvested from Hevea trees. Most gums are used chiefly in water-remoistenable products. SYNTHETIC ADHESIVE:- Although natural adhesives are less expensive to produce, most important adhesives are synthetic. Adhesives based on synthetic resins and rubbers excel in versatility and performance. Synthetics can be produced in a constant supply and at constantly uniform properties. In addition, they can be modified in many ways and are often combined to obtain the best characteristics for a particular application. The polymers used in synthetic adhesives fall into two general categories-thermoplastics and thermosets. Thermoplastics provide strong, durable adhesion at normal temperatures, and they can be softened for application by heating without undergoing degradation. Thermoplastic resins employed in adhesives include nitrocellulose, polyvinyl acetate, vinyl acetate-ethylene copolymer, polyethylene, polypropylene, polyamides, polyesters, acrylics, and cyanoacrylics. CONTACT ADHESIVE Contact adhesives or cements are usually based on solvent solutions of neoprene. They are so named because they are usually applied to both surfaces to be bonded. Following evaporation of the solvent, the two surfaces may be joined to form a strong bond with high resistance to shearing forces. Contact cements are used extensively in the assembly of automotive parts, furniture, leather goods, and decorative laminates. They are effective in the bonding of plastics. STRUCTURAL ADHESIVE Structural adhesives are adhesives that generally exhibit good load-carrying capability, long-term durability, and resistance to heat, solvents, and fatigue. Ninety-five percent of all structural adhesives employed in original equipment manufacture fall into six structural-adhesive families: (1) epoxies, which exhibit high strength and good temperature and solvent resistance, (2) polyurethanes, which are flexible, have good peeling characteristics, and are resistant to shock and fatigue, (3) acrylics, a versatile adhesive family that bonds to oily parts, cures quickly, and has good overall properties, (4) anaerobics, or surface-activated acrylics, which are good for bonding threaded metal parts and cylindrical shapes, (5) cyanoacrylates, which bond quickly to plastic and rubber but have limited temperature and moisture resistance, and (6) silicones, which are flexible, weather well out-of-doors, and provide good sealing properties. Each of these families can be modified to provide ad hesives that have a range of physical and mechanical properties, cure systems, and application techniques. HOT-MELT ADHESIVE Hot-melt adhesives are employed in many nonstructural applications. Based on thermoplastic resins, which melt at elevated temperatures without degrading, these adhesives are applied as hot liquids to the adherend. Commonly used polymers include polyamides, polyesters, ethylene-vinyl acetate, polyurethanes, and a variety of block copolymers and elastomers such as butyl rubber, ethylene-propylene copolymer, and styrene-butadiene rubber. PRESSURE SENSETIVE ADHESIVE Pressure-sensitive adhesives, or PSAs, represent a large industrial and commercial market in the form of adhesive tapes and films directed toward packaging, mounting and fastening, masking, and electrical and surgical applications. PSAs are capable of holding adherends together when the surfaces are mated under briefly applied pressure at room temperature TYPES OF ADHESIVES Adhesive Type Sources/Properties Common Uses Animal glue Obtained from animal byproducts such as bones, blood, and hooves Binding of abrasives in sandpaper and other grinding materials Casein Main protein in milk Labels on beer bottles that do not come off in ice water, yet are recyclable Starch From corn and maize Corrugated cardboard bonding Natural rubber Not sticky enoughby itself but is used as an additive in other adhesives Self-adhesive envelopes and other pressure-sensitive adhesives; adhesives that bond to substrates on contact (like tapes) Butyl rubber/isobutylene It is elastomeric-it stretches Additive for hot-melt adhesives, window sealants, and pressure-sensitive adhesives Amino resins Water-soluble adhesives Bonding of layers in plywood and the bonding of particles in particle board Polyurethane A flexible adhesive Bonding soles to the bodies of shoes; also used in food packaging Polyvinyl acetate Common whiteglue Book bindings and labels Polyolefin/ethylene copolymer No solvents involved Hot melts Acrylates or anaerobic adhesives Cure when air is removed Adhesive used to keep nuts tight on bolts, such as those within ATMs and heavy machinery Silicone Both an adhesive and a sealant and only common adhesive that is based on silicon rather than carbon Bathtub and shower sealants; also many car applications, such as oil pans and head gaskets Uses of Adhesives:- The exact combination of reasons will vary from case to case, but advantages should be sought in the following areas:  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Increased production speed. In comparison with other fabrication methods, adhesive assembly is essentially fast. Even if curing is required, this can often be accommodated off line, or combined with other processing stages such as paint curing.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Wider material selection. In contrast to welding, adhesives allow a wide freedom of choice during material specification. It is possible to mix and match material combinations to suit product function and save production costs in ways which have been impossible in the past. Traditional materials may be combined with new metal alloys, plastics, composites and ceramics to give distinct product advantages. Absorbing the full potential of this new freedom is perhaps one of the biggest challenges in finding significant market opportunities.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Design for manufacture. Adhesive assembly offers significant cost savings if material costs can be reduced and production operations can be simplified. There is sample evidence that this can be the case if the design and manufacturing functions co-operate to design or redesign the product with manufacturing in mind. New approaches can be taken to the manufacture of sub components, and castings may be combined with extrusions, sheet components and parts produced in a variety of other ways.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Better production sequences. Traditional assembly methods such as welding impose fairly rigid sequences during production, and frequently demand intermediate processing to remove contamination or rectify distortion. Bottlenecks can be removed, unnecessary operations can be eliminated, and work in progress can be reduced.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Low capital costs. Many adhesive operations involve manual application and the use of adhesive packages which have built in applicators. Even when mechanised or automated application is justified for high volume work, the equipment is usually lighter than would be used for welding.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Low production costs. This is a source of significant confusion Costs per tube of some adhesives may be high, but this should not be confused with all in production costs or cost per product. Cost comparisons should be based on the costs of the whole joining process, including plant, preparation and other pre-assembly costs, production and rectification expenses. All in cost assessments of this type provide a basis for accurate comparisons, and adhesive assembly may often give significant benefits. Advantages of Using Adhesives  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Dissimilar materials can be joined.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The bond is continuous.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Stronger and stiffer structures can be designed.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  On loading there is a more uniform stress distribution (Figure 2).  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Local stress concentrations are avoided.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Porous materials can be bonded.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Adhesives prevent catalytic corrosion.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Adhesives seal and join in one process.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  No finishing costs.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Improved fatigue resistance.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Vibration damping.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Reduced weight and part count.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Large areas can be bonded.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Small areas can be bonded accurately.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Fast or slow curing systems available.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Easy to combine with other fastening methods.  ·Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Easily automated/mechanised.
