Looming Tower Essay Example Looming Tower Paper Looming Tower Paper Lawrence Wrightââ¬â¢s, The Looming Tower: Al-Qaeda and the Road to 9/11. : Outline I. Introduction A. An overview of the book II. Discussion A. Discussion on the issues covered by the book. III. Conclusion and recommendations A. This part of the report will cover an overview of the books strengths, weaknesses, and recommendations. Introduction Wright has a special way of explaining things. When reading this book, a reader need not have a background knowledge on terrorism, Wright crafts the book in such a way that it consists of a ten page list of the main characters, fifty pages of notes, a list of interviews held, a bibliography and a clear bibliography for those who would love research the topic more. He also uses pictures of the main characters in the book, so that a reader can see the person being discussed. The book can be divided into two major parts with the first part focusing on giving the reader a comprehensive background and beginnings of militant Islam and the terror group Al Qaeda. In the bookââ¬â¢s first three chapters, the writer writes bibliographies of three important persons. He writes about an Egyptian named Qutb who is seen as the father of militant Islam, he also writes about Zawahri who also is an Egyptian and a co founder of Al Qaeda. The last character in the three chapters he talks about is Bin Laden who is the central character of the book. After reading the first three chapters a reader gets to learn about the internal politics of two most important countries in the history of Al Qaeda: Saudi Arabia and Egypt (Wright, 2006). The author tries to explain how the governments of both countries might have influenced the rise of radical Islam movement. This is helpful for the reader to understand why Al Qaeda is against everything represented by the West. Through the book, a reader can visit the towns and cities where these men grew up. After writing the bibliographies, the author then looks at the bigger picture and writes two chapters on Saudi Arabia. In these two chapters the writer talks of a spy master, Turki, who is instrumental in the search of bin Laden. The hapters also discusses the political and social structures of the Saudi Kingdom, the Soviet-Afghan war, the Afghanistan ââ¬â Pakistan border jihadist movement and lastly how jihadism has spread around the world. Wright at this point builds a strong groundwork so that when he starts to discuss about the Al Qaeda attacks a reader can understand the context. Wright then takes 200 hundred pages of the book to discuss the American Security and Intel ligence agencies, The FBI and CIA. He tells of how the agencies reacted to the first cases of jihadists. This section of the book ends with a chapter dedicated on Osamaââ¬â¢s life in Sudan (Bergen, 2010). The second part of the book looks at the Al Qaedaââ¬â¢s activities in the rest of the world. He begins by writing about how, in 1995, the Al Qaeda raided and bombed a building in Saudi Arabia that was housing Americans in the town of Riyadh. The chapters in this second part of the book are not very detailed and the writer talks of various key players. It is also in this second part we learn of the gruesome murder of tourist by Zawalhri. The author describes how Zawalhri stormed the Queen Hatchupset temple located in Egypt and killed all the tourists that were there. Wright then looks at the evolution of the terror group Al Qaeda on how they recruit, leadership, and their use of suicide bombers in carrying out their attacks. He looks and blames the actions of the CIA who had no right to with hold crucial information from the sole mandated agency, the FBI, to carry surveillance on the people who later committed the attacks. The last two chapters the author talks of the aftermath after the attacks. He explains in heart-wrenching details about the fear and desperation after the attacks. Wright in this book can be praised for his making it compelling and emotional. Discussion Al Qaeda is a terrorist group that has been behind many terrorist attacks. The book investigates some of their attacks especially the September 11 carried out in the United States. The author of the book, Lawrence Wright, is a famous writer and for his work Al Qaeda the Road to 9/11 won him a Pulitzer Prize for general non-fiction. The book largely focuses on the persons involved in the attack. It covers things like, who they are, reasons that drove them to undertake the attack, and the people they associated with closely. The book begins with Sayyid Qutb who is an Egyptian religious intellect. Sayyid visited the U. S during the 1940ââ¬â¢s, upon return to his homeland, he became an anti-West activist, and in the end, he became a martyr for his beliefs. The book also portrays Ayman al-Zawahiri, it looks at his story from childhood in Egypt and follows his life up to the time he participated and became the leader of the Egyptian Islamic Jihad. The Egyptian Islamic Jihad, the book states was later to merge with the Al Qaeda. The author in his book writes the story of head of Al Qaeda, Osama bins Laden. He traces Osamaââ¬â¢s childhood in Saudi Arabia where he was born and brought up in a rich family. The book continues to give a detailed account of how Osama participated in the war between Afghanistan and the Soviet Union. It writes of his role as a financier to terrorist groups, his life in Sudan, his stay in Afghanistan upon his return and his association with the Taliban. The book also covers on the 1998 terrorist attacks, which were done in Kenya and Tanzania as well as the bombing done on the USS Cole in the year 2000 (Wright, 2006). The author also writes of famous American who were involved, particularly Richard A. Clarke who at the time of 9/11 attack was the chief counter terrorism adviser sitting on the U. S National Security Council. The other personality featured in the book is John P. Oââ¬â¢Neill who was the assistant Deputy Director of Investigation in the FBI. Until his retire in August 2001, he was actively involved in the hunt for Osama bin Laden. After his retire from the FBI he headed the security of the World Trade Center where he was later to die in the 9/11 attacks (Bergen, 2010). The book covers some of the problems faced in the fight against terrorism, especially the lack of cooperation between the American Security Agencies, the CIA, and the FBI, which are blamed for not preventing the attacks. The Looming Tower is a story mostly based on the lives of the people involved in the 9/11 attacks rather than the attack. It focuses on the background and situations that led the perpetrators to plan and stage the attacks. The title ââ¬Å"the Looming Towerâ⬠is described as appearing in the Quran and according to the author Osama had uttered the words before the 9/11 attacks during a wedding he attended. The line is quoted from the fourth Sura of the Holy Quran and Osama is claimed to have said, Wherever you are, death will find you, even in the looming tower. â⬠When Mohamed Atta and his accomplices hijacked a Boeing 767 and flew the plane into the World Trade Center, a tragic story ensued. This attack was so gruesome that years down the line people still cringe at the mention of the events that took place that day. The events of 9/11 are in many ways a start of a tale or maybe the climax of a story that began years ago in different locations such as Cairo, mosques in Hamburg, streets of Jordan and the town of Greeley. This is a story of how few individuals from impoverished places planned and carried attacks on a world super power. It is also a story of how some individuals desperately tried to convince the government security agencies of an imminent attack. Many years after the attack questions were still being asked about the why and how a super power like America could fail to prevent it (ââ¬Å"The Plot against Americaâ⬠, 2006). The Looming Tower is full of details of how the Al Qaeda had once abandoned plans to stage an attack on American soil owing to the lack of foot soldiers that could pass credibly as westernized Muslims. Later the Al Qaeda found the credible persons to facilitate the attack in Atta, Ramzi bin al-Shibh, Ziad al-Jarrah and Marwan al-Shehhi, who had been attended schools in the United States. Wright gives accounts of Islamic Militancy in his book and looks at it from the intellectual, religious, and economic situation of the places where the attackers came from. Wright portrays a picture of Sayyid Qutb the man credited with the rise of modern day Islamist Fundamentalism. He shows Sayyid as a frail, middle-aged scholar who visited the United States and as a student in the university town of Greeley in the 1940ââ¬â¢s (Bolton, 2008). Sayyid is overwhelmed at the unrestrained luxuries and godlessness of the American culture. He was disgusted with the American women and how the women freely they expressed their sexuality. He writes, ââ¬Å"A girl looks at you, appearing as if she were an enchanting nymph or an escaped mermaid, but as she approaches, you sense only the screaming instinct inside her, and you can smell her burning body, not the scent of perfume, but flesh, only flesh. Tasty flesh, truly, but flesh nonetheless. â⬠Later Sayyid upon returning his country he started to write elaborate reasons why the Muslims should rise and wage war against the West and its rotten culture. Years later, the book writes of how Atta openly expressed his disgust for women especially from the West. The book is based on many interviews, which the author held with various persons. The interviews range from Osamaââ¬â¢s best friend from school, Jamal Khalifa and Yosri Fouda a reporter working for Al Jazeera. He also writes of the interviews he had with Richard A. Clarke who worked in the White House as a counter terrorism chief. In his accounts, the author gives the reader an intense view of the terrible events of 9/11. Though the events the author writes in his book have been told many times before, Mr. Wright tells the story with myriad new details. He gives accounts and describes them in the context of politics and culture. He focuses on the lives and occupation of the key players involved in the attacks while succeeding in writing a historical story that possesses all the propinquity and poignant power of a novel (Wright, 2006). The author writes that, ââ¬Å"The charisma and vision of a few individuals shaped the nature of the contest between Islam and the West. â⬠He further asserts, ââ¬Å"While the tectonic plates of history were certainly shifting, promoting a period of conflict between those two cultures. The emergence of Al Qaeda depended on a unique conjunction of personalities most notably Mr. Zawahri, who promoted the apocalyptic idea that only violence could change history, and Mr. bin Laden, whose global vision and leadership held together an organization that had been bankrupted and thrown into exileâ⬠(Wright, 2006). The author suggests that the events of 9/11 were evitable. Unfortunately, through bad luck, indecisiveness of American officials and war between the CIA and FBI contributed to the success of the attack by Al Qaeda. Compared to other writers like Peter L. Bergen who authored Holy War: Inside the Secret World of Osama bin Laden as well as Jonathan Randal the author of Osama: the Making of a Terrorist, Lawrence in his book does not concentrate on the role played by the Soviet- Afghan war in influencing Osamaââ¬â¢s jihadist cause. Rather, he draws his stories from documents written in Arabic and carries interviews with jihad activists who offer chronicles of the many things that influence Al Qaeda and the long road against America Osama took. The book gives a very detailed account of the Al Qaedaââ¬â¢s way of life, motivations, and doubts. It also goes further to give what each individual member wanted to achieve politically. The author captures certain events that are claimed to have influenced the Islamist Movement such as the execution of Sayyid Qutb by Gamal Abdel Nasserââ¬â¢s regime in 1966. In the eyes of the Islamist Movement Sayyid was a martyr and hero, this did not wane but increased their faith in the war against the West. Wright then goes on to describe how Osama, the heir of one the largest family fortune in Arabia, grows from a timid child into a religious adolescent. He says one of the most influential people in Ladenââ¬â¢s life was a charismatic gym teacher. This teacher was the one who introduced Osama to the Muslim Brothers Organization. Another person who influences Osama was Mr. Zawahri, who became acquainted with Osama in Peshawar in the early 1980ââ¬â¢s. Mr. Zawahri was a doctor from Egypt and in the book; he is drawn as the evil mentor who transformed the political view of the Young Saudi. The author argues that before Osama met Mr. Zawahri, he was ââ¬Å"not much of a political thinker,â⬠. The author goes to take a quote from Essam Deraz who was the first biographer of Osama. He says that he once thought Osama had the potential of becoming ââ¬Å"another Eisenhower,â⬠who could turn his celebrity status he had got after fighting in the Afghan- Soviet war into a serene political life(ââ¬Å"The Plot against Americaâ⬠, 2006). This is can be seen was not the plan Mr. Zawahiri had for Osama. The writer notes that as a young man, Mr. Zawahri was tortured in the Egyptian prisons and this powered his resolve to fight the Westernized culture. He is credited as pioneering the use of suicide bombers was seen from the start very keen to use biological and chemical weapons (Bolton, 2008).. For Osama, it took him a long time after leaving the war in Afghanistan to settle on a plan of action. In the time, he was exiled from Saudi Arabia and leaving in Sudan the author says that Osama ââ¬Å"was wavering the lure of peace being as strong as the battle cry of jihad. Agriculture captivated his imagination. â⬠It is further reported he was contemplated of quitting Al Qaeda and going into farming. The author tells of how after the first Gulf war the continued stay of the American troops in Saudi Arabia gnawed on Osama. He was also aggravated by the invasion of Somalia by American troops who were on a humanitarian relief mission. The Al Qaeda in 1992 the book claims met and ââ¬Å"turned from being the anti-communist Islamic army that bin Laden originally envisioned into a terrorist organization bent on attacking the United Statesâ⬠(Bolton, 2008). The book traces not only the evolution of Al Qaeda first as a resistance group to the Soviet and Saddam Hussein and then a sworn enemy of the United States, but also gives the reader a clear picture of life at an Al Qaeda training camp. The authorââ¬â¢s description of Osama bin Laden concurs with that made by security experts such as former CIA official Michael Scheuer. He states that Osama was not opposed to the American culture rather he was angry at the American political and military actions it was carrying out in Muslim countries(Bergen, 2010).. The author observes that Osama occasionally allowed his young sons to play Nintendo and in the Al Qaeda training camps, recruits would be allowed to watch Hollywood thrillers. Their favorite movies, as the book says, were those done by Arnold Schwarzenegger and tried to gather tips on being American from them. One of the many wives Osama had was known to love ââ¬Å"brand-name cosmetics and lingerie, preferring American products. He also had a wife who had graduated with a doctorate in child psychology (ââ¬Å"The Plot against Americaâ⬠, 2006). Wright is categorical in his book blaming former and present administrations for failing to prevent the 9/11. He writes of the failures in the CIA, FBI, and NSA refusal to share information with each other as the main reason the attackers were successful. If the agencies had cooperated, they might have foreseen the entering of two known terrorist in America. He blames the Bush and Bill Clinton administration of laxity in tackling problem of terrorism in the world. He notes that when Bush entered office terrorism was a low priority to his administration. Like other authors on the issue of terrorism, he criticizes the actions that the Clinton administration took after the 1998 bombing in East Africa. The administration of the day launched missiles at one of the Al Qaeda training camp located in Afghanistan and desperately failed to kill Osama. The writer notes helped turn Mr. Laden into a global celebrity and this allowed the terrorist to mythologize himself (Bergen, 2010).. Wright writes, ââ¬Å" Mr. in Ladenââ¬â¢s goal in striking the American embassies and bombing the American destroyer Cole in 2000, was to lure America into the same trap the Soviets had fallen into: Afghanistan. His strategy was to continually attack until the U. S. forces invaded; then the mujahedeen would swarm upon them and bleed them until the entire American empire fell from its wounds. It had happened to Great Britain and to the Soviet Union. He was certain it would happen to America. When neither the embassy bombings nor the Cole bombing was enough to provoke a massive retaliation, Mr. Bin Laden decided he would have to create an irresistible outrage. The outrage in this case happens to be the 9/11 attack. The author continues to write that Laden had gotten what he wanted and cites the 2001 invasion of Afghanistan and the 2003 attack of Iraq as his wins. In both this invasions, the American Army has seen deaths of more than 2500 soldiers, just the thing that Osama fervently wanted (Bolton, 2008). In the book, the writer portrays what has caused the Islamic militancy. He says at the heart of Islamic militancy lays anger, hatred of modernization, and feeling of humiliation which terrorist group cite as reason for killing. The author looks at failure of autocratic governments to offer their citizens reasons to face the future as the reasons why some of this terrorists turn to Islam, which offers dignity and hope more so in death. He says that these ââ¬Å"theological amateur,â⬠will turn to be religion extremist and join terror groups(Bergen, 2010).. Atta and the hijackers felt this as the author writes, ââ¬Å"Their motivations varied, but they had in common a belief that Islam - pure and primitive, unmitigated by modernity and uncompromised by politics - would cure the wounds that socialism or Arab nationalism had failed to heal. They were angry but powerless in their own countries. They did not see themselves as terrorists but as revolutionaries who, like all such men throughout history, had been pushed into action by the simple human need for justice. Some had experienced brutal repression; some were simply drawn to bloody chaos. From the beginning of Al Qaeda, there were reformers and there were nihilists. The dynamic between them was irreconcilable and self-destructive, but events were moving so quickly that it was almost impossible to tell the philosophers from the sociopaths. They were glued together by the charismatic personality of Osama bin Laden, which contained strands, idealism, and nihilism, in a potent mix. â⬠Before there was proof of an imminent attack as the book talks of John Oââ¬â¢Neill who was a supervisor for the FBI in their offices in New York. John Oââ¬â¢Neill and the team he headed were assigned to trace and find information about Al Qaeda operatives in America. Oââ¬â¢Neill had the hunch that the Al Qaeda was preparing to stage an attack on the American soil. He was an ardent investigator and when he saw the agency was not taking him seriously, he quit. After quitting, he said he could not work for a government bureaucracy that did not intend to move quickly to avert an attack as he did desperately trying to do. It is unfortunate that Oââ¬â¢Neill was among the people who died during the 9/11 he had foreseen. Other agents in the bureau had premonitions of the Al Qaeda being successful in making attack on America. The supervisor posted in the Minneapolis office was cautioned in the month of August for raising his fears of an attack happening. He expressed fear that a known Islamic radical was attending a flight school could have been as well planning an attack. When being admonished he retorted, ââ¬Å"I am trying to keep someone from taking a plane and crashing into the World Trade Center. â⬠Astonishing you might say (ââ¬Å"The Plot against Americaâ⬠, 2006). The Author talks of how the CIA had information of high level Al Qaeda members had attended a meeting in Malaysia in the early months of 2000. He says they also knew of two of those who attended the meetings had entered America. This two would later play a role and implement the attack as was later uncovered. The CIA had failed to avail this information the FBI, which is mandated to carry out internal surveillance of known and suspected terrorists. The struggle between the two agencies is highlighted in the book as the author writes of a meeting held prior to the attack. In the meeting CIA analysts are claimed to have dangled pictures of would be attackers at the faces of FBI agents. When the CIA agents refused to give the information they had on the two, the FBI agents realized they were the same persons they were pursuing and the tension between the two agencies increased. Three months prior to the attack, both agencies held a meeting, which ended in both the FBI and CIA agents shouting at each other. In the book, the author illustrates a scene where an FBI agent named Ali Soufan reacts after being shown the pictures of the terrorists. Ali Soufan was working on the Al Qaeda case and when on September 12 he was shown the names and pictures of the hijackers, he just rushed into the bathroom and threw up. These people the CIA had information about their activities but refused to share with the FBI (Bergen, 2010). The writer has covered many things in his book, though it seems he left out some important things such as the hijackings. There is no chapter that the writer explicitly discusses the hijacking as he has on so many things. He takes the reader straight to the moments of the burning towers. This maybe he did thinking that many other authors had covered it and wanted to be different. The other thing about the book is the way the author draws up verbatim reconstruction of various conversations. He travels a lot in such of this information and writes of conversations that had taken place more than a decade before. This brings the question of how true and detailed the conversations are because it is hard to believe people have such good memories. The book ends with Zawahri or someone else riding a horse on the border of Afghanistan and Pakistan. This person disappears into the mountains and the book lacks a definitive end. This is a point the author tries to put that the story about the Al Qaeda is still not over (ââ¬Å"The Plot against Americaâ⬠, 2006). Conclusion and Recommendation The book focuses on the lives of two men who have shaped the Al Qaeda. He tells of the Egyptian doctor al- Zawahiri and the life of Osama bin Laden. Wright skillfully dissects the relationship the two have. He gives on one hand the story of the ideologist al-Zawihiri, who is a skilled combatant and on the other hand, he tells the story of the determined and charming Osama bin Laden. From their first interaction in the 1980s, the author follows how they join to form Al Qaeda and how al-Zawahiri mentors Osama. Wright gives accounts of how the attack affected the United States and the most depressing scene is that of Ali an FBI agent throwing up after realizing the CIA had knowledge of the people responsible. The book as seen is a magnificent read and ay person looking to learn about the rise of the Al Qaeda should look for this book. The book gives detailed accounts of occurrence that happened before the 9/11 attack. It also looks into the lives of those people who are seen as instrumental in the rise and growth of the terror group. Wright in his unique intelligent way delivers the occurrences and reasons of the attack on American soil with emotion. The strengths of this book in informing about the road to 9/11 lies in the deep research the writer carried out and the way he reconstructs conversations that had been taken more than a decade ago. This is also the greatest weakness of the book owing to questions of how true these conversations are because people are not known to have search kind of memory. References Bergen. P. , (2010).

Deciphering The Presidentials Tapes Watergate essays
Deciphering The Presidentials Tapes Watergate essays Ever since I can remember I have always heard, whether over the news or on an educational channel, about the Watergate scandal. I never knew what the Watergate scandal was about, but I did know that it had to do with one our former Presidents. Before I read Breaking into Watergate I had no clue about all the lies and betrayals that went on in the highest and most prestigious office in America. It is very important as a history major to have read this article so that I am no longer oblivious to what went on in the Oval Office prior to June 7, 1972. As I started to read through this article the realization of what the Watergate scandal was, became more and more clear. The information that I read was very upsetting and discomforting. To know that a President of the United State would be so deceitful and disloyal to not only his piers but also to the people of the United States is very upsetting but unfortunately is not too uncommon these days. Reading about President Nixon trying to bribe witnesses with money and trying to blackmail the opposition was mind boggling. President Nixon did almost everything perfect and might of slipped past the accusations except for the fact that he forgot about the tapes that recorded his phone conversations. Donald Sanders was very smart to think of something that none of the other investigators thought of; a tapping system. Alexander Butterfield, when reminded that he was under oath, admitted that there was a recording system in the White House which no longer made John Deans testimony just his word against the Presidents(Breaking Into Watergate, 341). Knowing that John Dean would stand up and tell the truth, despite being told to do otherwise, makes at least one good moral story come out of the scandal. In the thirty years that the presidents had been making secret recordings, on and off, all of them had their different reasons. In nineteen forty Franklin Roosevelt had a...

Appendix A Review on the Marketing Strategies of TAFE Institutions in Queensland Executive Summary The main objective of this report is to review how the three major Technical and Further Education (TAFE) institutes in Australia market themselves. The TAFE institutes play an important role in equipping the students with the job market skills. A major proportion of students who complete their high school land into such institutes directly as they will be able to attain part-time or full time jobs much earlier than th ey get the college degrees through these institutes. However, the marketing strategies of many such institutions are outdated. This report conducts an elaborate survey among the students who study in the three major Australian TAFE institutes, the Metropolitan South Institute of TAFE, Southbank Institute of Technology and Brisbane North Institute of TAFE. ... The third part presents the gathered results and discusses the current pros and cons of the TAFE marketing strategies. The fourth part presents productive recommendations to improve the reach of their TAFE institutes among the student community through various innovative marketing ideas. Introduction Background of the Study In Australia TAFE colleges award diploma's which are valued less than the Bachelor degree, but very useful in equipping students with industry related skills. Certain TAFE colleges in Victoria and Queensland are eligible to provide their own bachelor and post-graduate degrees ( Wheelahan, et al, 2009). These colleges offer a variety of vocational training in various fields like mechanics, engineering, finance and construction. Students looking for a quick employment and those who cannot afford university education find TAFE colleges quite useful. Students who finish year 12 examination attain a short term diploma course and secure a job. The diploma course is then used as a partial credit to enter Bachelor degree courses in the mainstream universities. The students, who come follow this path, easily earn while they learn and come out with substantial experience in their field when they complete their degree. This extra qualification helps them gain up to three times more salary than their fresher colleagues. TAFE colleges are usually widespread offering a variety of industry niche oriented training. But many students who complete year 12 look upon them as colleges used by students who get low grades and economically backward students. They are not well informed about the advantages of using the TAFE diploma's efficiently. Most of the youngsters who complete year

1.Explain how an understanding of psychological theories and Essay
1.Explain how an understanding of psychological theories and approaches might contribute to career management from an individual and organisational perspective - Essay Example This means that there is tremendous room for improvement both from the individualsââ¬â¢ perspectives as well as from the companyââ¬â¢s standpoint, since the company is the one which can benefit in the long run, in terms of revenues, increasing sales trends, changing (and positive) consumer recognition models and recall patterns and so on and so forth. The effective handling of staff ensures that their careers are developed in a proper and adequate manner and there is understanding between the corporations and their staff members. Career managementââ¬â¢s main task is to maintain the careers of the employees who have been enrolled on the active roster of an enterprise or a company and thus bolster their careers in the light of growing trends, changing circumstances and problems that might arise from time to time. This also means that employees are better understood by the organizations not only with regards to their own individual standpoints but from the whole industryââ¬â¢s stance as well. This can be a positive sign since people would trust the initiatives which are taken by the corporations and thus aspire to contribute in a better and more productive manner as and when the need arises. Moving ahead, advances in different fields of technology have done a great deal to produce miraculous devices and solutions. In some circumstances however, these advances have created problems for the elderly. More aggressive technology approaches are used to extend the life of the elderly. On the whole the elderly, as well as others, welcome that development -- even if they fear some of its consequences. In this context, here we discuss the health information management profession and the careers attached with the same. A number of different institutions and educational centers have of late endeavored to expand their business and hence the field of

Obstacles Teachers May Face Essay Example for Free
Obstacles Teachers May Face Essay The process of how an individual learns is based on the theories surrounding behaviorism, conditioning, modeling and self regulation. Students can be problematic if proper resolutions arenââ¬â¢t put in place when a dilemma arises. There is a great emphasis on the importance and relevance in motivating the students in the classroom. Without the knowledge of extrinsic and intrinsic motivation and what drives students to learn, teachers may not know what inspires or how to encourage students to work to the best of their ability. Teachers must portray themselves in a professional manner at all times, whether they are dealing with students, parents or colleagues. Professionalism can be defined in several ways and some characteristics of a professional teacher include being committed to learners in a way that incorporates a code of ethics, have the ability to make routine and efficient decisions in a complex and ill-defined situation, conduct a critical self examination of oneââ¬â¢s teachings, i. . reflective practice, and acquire the element of professional knowledge to constantly improve, develop and expand oneââ¬â¢s methods of teaching to maximize learning environments (Eggan, P. Kauchak, D. 2010. pp, 4 ââ¬â 6). One obstacle a teacher may face is if he or she gets asked a question that they donââ¬â¢t know the answer to. Students look up to teachers and depend on them for the knowledge they require (Yero, J. L. , 2002. P173). Understanding each topic is simply not enough; a teacher needs to be able to represent topics in an understandable way that is appropriate to the age of the learner. For example, the solution to explaining how to multiply numbers is to firstly acquire the knowledge of content then illustrate how to multiply the numbers. This is referred to as pedagogical knowledge. Pedagogical knowledge requires the teacher to understand principles of instructional strategies and classroom management. Involving each student in the learning process in order to enhance productive learning comes with knowledge and experience. Instructional strategies that promote productive learning include: selecting topics that are important for students to learn, provide clear learning objectives and prepare learning activities respectively, design assessments that relate to the workload and maintain the instructional alignment between the three, i. e. the connection between learning objectives, learning activities and assessments (Eggan, P. Kauchak, D. 2010. pp390 ââ¬â 394). A teacher must have a positive and caring attitude, be organized, communicate effectively, respect and encourage rather than punish and constantly question and prompt incorrect answers to manage a productive classroom (Nelson, J. , Lott, L. Glen, S. p20-27). Identifying clear standards of acceptable behavior i. e. rules, be supportive to each student and create a sense of equilibrium are all strategies to ensure a produc tive and manageable classroom. The aim of all teachers is to promote as much learning as possible. Behaviorism focuses on the idea that learning is ââ¬Å"influenced by stimuli from the environmentâ⬠(Eggan, P. Kauchak, D. 2010. p,164). For example, feeling nervous before an exam is a learned behavior due to previous experiences/knowledge of exams. This feeling is involuntary to the individual, and it is referred to as classical conditioning. Classical conditioning can be positive or negative, depending on which, it can have different effects on the learner. If the teacher uses positive reinforcement within the classroom the students will gradually associate learning to the teacherââ¬â¢s manner and thus feel safe within the classroom resulting in a productive learning environment. In contrast negative or non-reinforcement results in the cessation of a behavior and results in a classroom environment that is not productive. Children learn acceptable behaviors through observing adults, therefore teachers are role models, and it is important for a teacher to demonstrate respect, tolerance, and values to motivate learning (Call, N. Featherstone, S. 2004 p. 47). Cognitive modeling is essential to the learning process as teachers use this to perform a demonstration and verbalize the thinking behind the actions taken (Eggan, P. Kauchak. D. , 2010. p. 182). An obstacle one may face is if some children are having trouble learning how to pass a netball to one another. Often, children instinctively bounce the ball, instead of passing it, as clas sical conditioning has taught them to do so from a young age. The teacher must describe oneââ¬â¢s thoughts of how to pass a netball, whilst performing the action, which in turn encourages students to verbalize their understandings in any situation, resulting in a productive learning environment. Modeling is the key concept of social cognitive theory. Cognitive, behavioral and emotional change in children is a result of observing models. Modeling affects people by learning new behaviors, facilitating existing behaviors, changing inhibitions and by arousing emotions (Eggan, P. Kauchak, D. 2010. p. 183). These observations lead to learner expectations, which in turn are accomplished through self-regulation. Settings goals and monitoring that progress is an essential element of learning. The student observes another student passing the netball. He then models the observation, uses that experience to expand his knowledge thus takes responsibility and control of his learning. Teaching is constantly developing and changing, and the need for motivation is a necessary procedure to support and increase student learning and the teaching process. A common obstacle teacherââ¬â¢s face is how to motivate uninterested and unengaged students. Some students seem naturally enthusiastic about learning, but many need or expect their instructors to inspire, challenge and stimulate them. An unmotivated student is likely to choose work that is inappropriately easy, show a negative attitude, give up quickly and leave tasks unfinished. This can disrupt the students around him and cause interruptions in the learning environment (Nelson, J. Lott L. , Glenn, S. 1997 p. 72). There are two broad forms of motivation; extrinsic ââ¬â where some students will be motivated by the approval of others, for example, by getting a good grade, and intrinsic motivation, where the learner studies in order to understand the content presented to them because they like the challenge and want to perform (Eggen, P. Kauchak, D. 2010. p. 287). To encourage students to become self motivated and independent learners, teachers can give frequent, early, positive feedback. This supports the students beliefsââ¬â¢ that they can, and are doing well as viewed by the humanistic theory of motivation. The teacher can also help students find personal meaning and value in the material as viewed by cognitive and social cognitive theory of motivation, and create an atmosphere that is open and positive which help students feel that they are a valued member of the learning community which is based on the socioculural theory of motivation. In addition, a teacher can ensure opportunities for studentsââ¬â¢ success by assigning tasks that are neither too easy nor too difficult which is a view shared by behaviorist theories (Eggen, P. Kauchak, D. 2010. p. 289). It must be understood that individuals are motivated through a wide variety of needs. While teachers canââ¬â¢t make or teach students to be self-motivated, they can encourage and promote this highly desirable trait. To conclude, there are many solutions to the obstacles a teacher may face in a learning environment. A teacher should act and approach a classroom with a professional attitude and an academic manner by being knowledgeable and recognizing the importance for assessing oneself. Teachers must be aware of the influence they make on studentsââ¬â¢ learning and how to promote positive and engaging classroom environments in order to solve the dilemmas they may be presented with in regards to behaviors students display. Furthermore, teachers need to understand that the process of motivation stems from stimulation, which in turn is followed by an emotional reaction that leads to either a positive or negative behavioral response. By understanding the theories based on solutions to the problems a teacher may face in the classroom, they may have a better chance at expecting when a problem may arise, and resolve the situation immediately.

The Sweet Thereafter Summary :: essays research papers
The movie and the novel 'The Sweet Thereafter'; had a few minor differences. Two of the differences that I would like to point out are the two that I consider being the two most important. The first topic of discussion in this paper is the picture on the front of the book and the meaning of it. The second topic I would like to bring up is the relationship between Mitchell and Zoe. The changes between the two are important, however, the main plot does not change between the movie and the novel. The first comparison I would like to make is the picture on the front of the book. The picture shows how the story affects Mitchell's life. After reading the book, watching the movie, and listening in class I realized how they reflect each other. The family on the front of the book is Stevens family. This picture was when Zoe, his daughter, was young. The mother and daughter appear to be very close. The reality within the picture is that Mitchell is not quit as close as they appear. Mitchell did not want to be that close to his family simply because he feared being to close and then losing them. The picture reminds me of the trip that the family took to North Carolina. This image comes from the end of their vacation. In the picture he seems like he is trying not to get to close to his family. One reason for this is the scare he went through with his daughter, Zoe. The scare the family went through was when Zoe got bit by a spider. When she started to swell up, her mother drove while Mitchell had to keep Zoe calm. To add to the scare Mitchell was going to have to do an emergency tracheotomy if her throat was to swell shut. They did, however, make it to the hospital on time. After getting back home that evening the mattress that Zoe slept on was burned. From that night and for the rest of the vacation Zoe slept with her parents. All during the scare with Zoe, Mitchell felt like he was two different people, a father and a doctor. The father role that he was playing was to keep his daughter calm. The doctor role of the situation was holding onto the knife ready to cut into his daughters throat at anytime, ready to save her life.

Marriage: Is It in Crisis?
Marriage in America Burin Bianca Ramirez October 11, 2012 Marriage: Is It In Crisis? In America, it is the traditional thing to do to get married to someone in order to spend the rest of your life with. Someone to go through the ups and downs of life with, someone to be there to support you no matter what, and even in most marriages someone to have children with and to create a family. All these are perfect examples of why people get married, so why wouldnââ¬â¢t you want all of these things in your life? Well society as we know it today is declining in all aspects including, economics, the work force, and even health care.It is no wonder why people have come to the realization that marriage is in crisis because of everything that is going on around us. In the articles I read, ââ¬Å"The Marriage Crisisâ⬠, ââ¬Å"Pimp My Brideâ⬠and ââ¬Å"Few Good Menâ⬠there are different viewpoints and takes on my marriage is in trouble. The most important points I will be making and elaborating on in this passage about why marriage in in crisis today will be the realization people are coming to about a worthy marriage, how the media portrays marriage, and the economic and emotional state of marriage.While explaining these points we will ask ourselves, is marriage in crisis? In the earlier 1900s people were getting married for usually one reason: Stability. Times were hard back then and the only way people could make a living was if they had a ââ¬Å"partnerâ⬠to help out with a household/farm while the other spouse went out in the work force to earn a living and put food on the table. Having someone help you out with things at home makes things easier and thatââ¬â¢s why they formed almost a business like partnership. In the article ââ¬Å"The Marriage Crisisâ⬠, it explains the declining of marriage and the rising of cohabitation.This brings up my first point which is the realization people are coming to about a worthy marriage. In other words, people can now fend on their own, especially woman. Today, women have more rights and are able to participate in the work force just as much as men are. Woman are more independent now more than ever before and because of this they donââ¬â¢t need to force themselves in a marriage they donââ¬â¢t want to be in just so they are financially stable. This is why cohabitation exists. People want to know a person for a long time before they make any commitment and rush into a marriage without fully knowing the good and bad in a person.In addition to womenââ¬â¢s rights, marriage is declining because women also have the power of education. Women are now getting degrees, making their own money (not having to rely on a man), and gaining a sense of personal fulfillment and to some women personal fulfillment is a lot more rewarding than fulfillment from a marriage. On the topic of marriage and society now, media comes into play. Technology has emerged excessively in the last decade, and w ith technology comes media. Of course there are many different sources of media but weââ¬â¢ll just focus of television.In the article ââ¬Å"Pimp My Brideâ⬠, the author Judith Halberstam explains the world of marriage on reality television based program. She includes shows like The Bachelor, Average Joe, and Joe Millionaire. All these shows portray one message: how marriage is outside of normal society which includes financial responsibilities, children, families, work, and other outside conflicts that usually affect a normal relationship/marriage. Halberstam explains how these reality television shows are known as ââ¬Å"survival of the cutestâ⬠where these shows are simply based on looks, although they try to mix in personality with it, it usually doesnââ¬â¢t work that way.Shows like The Bachelor are scripted programs that only get our hopes up and make us think that marriage is perfect and nothing gets in the way of that relationship. Well that is totally wrong. W hat they donââ¬â¢t show is how marriage really is outside of that program. Usually with these shows, once the couple returns back to reality and to their normal lives, the relationship rarely lasts because conflicts that normal couples go through are suddenly hitting them and they realize that the perfect relationship they had before is not going to work in reality.This is why it is important to realize that these are just shows and you need to be smarter than to believe that your relationship/marriage is going to be as perfect as the ones you see on television. Those shows are strictly for entertainment purposes. Stepping aside from reality television marriages, and their ââ¬Å"perfectâ⬠relationships, there is a need to talk about the reality of marriage. Do people get married? Of course they do. Do people get divorced? Of course they do. Why?When you marry someone it is because at that time you can see spending the rest of your life with them, but things can change and p eople can change and if you canââ¬â¢t seem to accept those changes divorce is usually the answer to get away from that and that is perfectly okay. I am a firm believer that if you are not happy in your marriage you have the right to divorce. I understand the spiritual side of marriage and how that can be a process and that there needs to be an appropriate reason for an annulment but overall people still have the right to break off a marriage that isnââ¬â¢t happy anymore.Why spend the rest of your life with someone you canââ¬â¢t be fully happy with, that is just making yourself suffer and can affect you in many different ways. If you do get divorced, you can always remarry and hopefully find your soul mate. On the other hand, remarrying is not for everyone. In the article ââ¬Å"Few Good Menâ⬠, we notice a focus on single low-income women and their views about marriage. In their eyes marriage is more of a risk than a reward because they feel that nothing is certain or p romised in a marriage.With all the hardships they already have to go through now, having a marriage in which the husband beats them, abuses their children, who is controlling, or is unfaithful is just not worth the risk, and theyââ¬â¢d rather stay single and fend for themselves rather than depend on someone who is not suitable for them. Now, they are not saying that they wouldnââ¬â¢t marry a man; he just has to be the right one, and to be completely honest there arenââ¬â¢t a lot of those kinds of men left. Marriages in low-income couples are not likely to last because of affordability, respectability, trust and control.Low-income couples sometimes do not work out because they depend of both the husbands and wifeââ¬â¢s income. If a husband were to lose or quit his job the amount of necessities they can afford is very little. And when you add children to a household with two parents but only one income in an already low-income marriage, there is only enough supplies to go around for the children and very little left for the one providing and the one that is jobless, in this case the husband, is the one that doesnââ¬â¢t get anything which leads to marriages falling apart.In communities that are low-income based you would think that people there would not take marriage seriously but that is not the case. Women in those communities think of marriage as a ââ¬Å"sacredâ⬠thing and they take it seriously. They all want that big, huge wedding that is magical just like everyone else. So they stray away from marriage because theyââ¬â¢d rather not have a marriage in which the partner doesnââ¬â¢t take it seriously enough and doesnââ¬â¢t meet their expectations. Trust is also a big reason why women in these communities arenââ¬â¢t getting married.They simply just cannot trust men enough to marry them. They explain that at the end of the day ââ¬Å"men will be menâ⬠and engage in an outside affair with another woman, and they will not put up with someone who is unfaithful. They also cannot trust them with handling money. It is not fair to the hard working women who are trying to pay the bills when the husband is spending their money on junk when they should be saving up and keeping that money handy for their children. And lastly, women feel that they cannot trust their husbands with their children.In the communities that they live in things like drugs and narcotics are easy to get a hold of and the women fear that the husband could be exposing their children to drugs and sadly, even sexually abusing their children. These make up all of the characteristics as to why poor women donââ¬â¢t marry. Based upon the evidence provided by the authors and their articles, I do in a way think that marriage is in crisis. People have such high expectations in what they want their marriage to be like, and they should aim for something high. In everything that is going on in the world now, people are entitled to be in a happy marr iage.Now, I am not totally convinced that marriage is in crisis. For those that do get married usually do it for the right reason: to be with the one you love for the rest of your life. Those marriages, I feel, are not in crisis. They understand the true meaning of loving someone unconditionally and they want to be in a marriage. So I other words, those who marry and donââ¬â¢t take it seriously are the ones that have marriages in crisis, but those who value marriage as a scared union help me believe that a happy marriage is still out there and it can be something to look forward to.In conclusion, society view marriage is in crisis because of all the changes that are going on around us and how it affects the institution of marriage. Economics and the work force take a toll on marriage today and put a strain on some aspects of marriage. People realizing the worthiness of a good marriage and the expectations they have on marriage has affected the decline of marriage and couples foun d cohabitation as an alternative of marriage. Media has affected the institution of marriage immensely through the works of reality television and how they portray marriage in a ââ¬Å"fantasy worldâ⬠rather than the real world.And lastly, marriage in low-income based communities is declining because of characteristics such as affordability, respectability, trust and control. So in essence, is marriage in crisis? I believe there is not right answer simply because the marriages in which the couple does not take the union seriously does put the institution of marriage in crisis but the few marriages that are perfectly happy are the ones to look up to and strive towards later on in life.

Black People and Aunt Alexandra Essay
1. How does Jem change? Be specific. a. Page 115-Scout explains that Jem doesnââ¬â¢t want her hanging around him all the timeâ⬠¦Ã¢â¬ stop pestering me. â⬠And Calpurnia begins referring to him as Mister Jem now, a title usually reserved for adults. b. Page 116-ââ¬Å"Jem developed a maddening air of wisdom that summer. â⬠Meaning that he is rational now and understands thingsâ⬠¦not like a little kid anymore. He helps to put things into perspective for Scout that she doesnââ¬â¢t understand. c. Jem is growing up. He is trying to make sense of things he sees, trying to be like Atticus, and trying to put behind him childish games and youthful pranks. Consequently, sometimes he is moody and sometimes occasionally seems to lord his authority over Scout. 2. What are the minor disappointments that start the summer for Scout? What do they foreshadow? a. Page 115-116- READ ALOUD- Atticus got called to an emergency session of legislature, Dill is not coming to visit for the summer, and Aunt Alexandra arrives unannounced to live with them. b. These small disappointments foreshadow the trial of Tom Robinson. 3. What is ironic about Jem and Scoutââ¬â¢s visit to Calpurniaââ¬â¢s church? Explain. a. Page 119-120- READ ALOUD TO CLASS- The children experience prejudice against them. They donââ¬â¢t possess prejudice and neither does Calpurnia. They are surprised when church goer Lula confronts Cal asking her how she could bring white kids to the black church. b. However, just as not all the white people are prejudiced, not all the black people are prejudiced. Zeebo and Reverend Skyes are both welcoming to Scout and Jem. 4. Everybody is beginning to tell Scout to act like a lady. How is it ironic that her church and Calpurniaââ¬â¢s church deliver the Impurity of Women doctrine every week? a. Page 122- This is ironic because everybody wants her to be like a lady, but then they discuss the evils that women bring on the world throughout the Impurity of Women Doctrine. This is confusing for Scout. 5. What does Scout learn about Calpurnia? Why is this important? a. Scout learns that Cal leads a separate existence from her household and taking care of her and Jem. Scout sees that Calpurnia speaks a different way around her people than she does with Jem and Scout. This is important because it helps Scout learn to continue to try to see beyond just her world. 6. Why is it unfair that blacks are not allowed to go to school, but the Ewells are? Explain. a. Page 124- READ ALOUD TO CLASS- The Ewells are trash people and no good who walk out of school, but the blacks really want to learn and would go to school regularly. 7. Why did Aunt Alexandra say she would be staying with Atticus and the kids? Do you think this is true? What do you think her real reason is? Explain. a. Page 127-She felt Scout needed a feminine influence. b. She was probably asked to come by Atticus to watch the kids while the trial is going on and try to help them absorb and shelter them from some of what is going on. 8. ââ¬Å"Aunt Alexandra fitted into the world of Maycomb like a hand in a glove, but never into the world of Jem and me. â⬠Explain. a. Page 131-132- READ ALOUD TO CLASS- Aunt Alexandra knew all the proper social things to do and say, and she knew a great deal of the history of the local families. She joined some clubs and entertained at her home, and generally did fit right into townââ¬â¢s society. However, Alexandra didnââ¬â¢t understand or agree with the values by which Atticus was raising his children. Therefore, she did not understand the childrenââ¬â¢s behavior. Because their value systems were different, they were more often than not at odds.

Not Poor, Just Broke Essays
Not Poor, Just Broke Essays Not Poor, Just Broke Paper Not Poor, Just Broke Paper I learned most emotions from school. You would think I would have learned most of my feelings from my home life, but I think my parents did the best they could to cover them up and make it seem like everything was fine and dandy. I grew up in a museum of sorts, or a playhouse. Everything was staged and we had to act in a proper manner to make it look like we had a perfect life. When my mom was upset, she would pull herself together in a moments time and say we need to ââ¬Å"keep up appearancesâ⬠so no one was the wiser. I would pay close attention to my parents to try and iscover how they really felt, but they were remarkable actors. So I became a player, performing in my own life as well. It was in school where I learned what real emotion was. And how to handle it. How do you pretend one way when you feel another way? I would imagine that is why some of the other kids act out. They are in a certain life, pretending to be something they are not but donââ¬â¢t want to let on t o the truth of their real emotions. I remember this other student who went to school with me. I felt bad for him most of the time because he always came to school kind f dirty and shabby. His family barely had any money and I donââ¬â¢t think his father was around. One day in class, there was a big scene when the teacher made it a point to single him out as a needed student and mention that everyone knows he doesnââ¬â¢t have a father. Iââ¬â¢m not sure about his family but he seemed to just barely be holding it together. The teacher picked on him a lot, which I know bothered him. It bothered me as well. I felt sad for Page 2 of 2 him, but then I would remember my mother and trying to keep up appearances. He had a crush on my friend. I donââ¬â¢t think e knew that we all knew he liked her. I felt ashamed that we would make fun of him behind his back and call him names. I think back about how I use to act differently with my friends at school than I did at home. I wish I had learned more from my patents because I know now that most of my childhood friends were not the best influence on my developing emotions. That day when the teacher picked on him, I felt asha med. But I just kept smiling and pretending nothing was wrong. I wish I would have reached out to him and been a little more nice. It was a lesson well learned.

Hubble Studies Giant Gas Bubbles Near our Galaxys Core
Hubble Studies Giant Gas Bubbles Near our Galaxy's Core Its an ancient galactic mystery with a modern explanation: two million years ago, something happened at the center of our Milky Way galaxy. Something energetic. Something that sent two huge bubbles of gas billowing out to space. Today, they stretch out across more than 30,000 light-years of space, extending above and below the plane of the Milky Way.à No one was around to see it then at least no humans on Earth. Our earliest primateà ancestors were just learning to walk upright, and astronomy was not likely on their list of activities. So, this major explosion went unnoticed. Yet, it was a titanic event, driving gases and other material outward at two million miles per hour, didnt affect our plane then and it wont likely affect us in the future. However, it does show us what happens when a massive explosion occurs some 25,000 light-years away from our planet. Hubble Sleuths the Cause of the Explosion Astronomers usedà Hubble Space Telescopeà to look through one lobe of the bubbles toward a very distant quasar. Thats a galaxy that is very bright inà both visible and other wavelengths of light. The quasars passed through the bubbles of gas, which allowed Hubble to peer inside theà bubble to learn more about it- likeà looking at a distant light shining through a fog bank.à The enormous structure illustrated in this image was discovered five years ago as a gamma-ray glow on the sky in the direction of the galactic center. The balloon-like features have since been observed in x-rays and radio waves. The Hubble Space Telescope presented a good way to measure the velocity and composition of the mystery lobes.à With the data from HST,à astronomers will work on calculating the mass of the material being blown out of our galaxy. That might also let them figure out just what happened to send all this gas billowing out of the galaxy in the first place. What Caused this Massive Galactic Explosion? The two most likely scenarios that explain these bipolar lobes are 1) a firestorm of star birth at the Milky Ways center or 2) the eruption of its supermassive black hole.à This isnt the first time that gaseous winds and streams of material have been seen coming from the centers of galaxies, but its the first time astronomers have detected evidence for them in our own galaxy.à The giant lobes are called Fermi Bubbles. They were initially spotted using NASAs Fermi Gamma-ray Space Telescope to track gamma-rays.à These emissions are a powerful clue that a violent event in the galaxys core aggressively launched energized gas into space. To provide more information about the outflows, Hubbles Cosmic Origins Spectrograph (COS) studied the ultraviolet light from a distant quasar that lies beyond the base of the northern bubble. Imprinted on that light as it travels through the lobe is information about the velocity, composition, and temperature of the expanding gas inside the bubble, which only COS can provide. The COS data show that the gas is rushing from the galactic center at roughly 3 million kilometers an hour (2 million miles an hour). of the gas at approximately 17,500 degrees Fahrenheit, which is much cooler than most of the 18-million-degree gas in the outflow. This cooler gas means that some interstellar gas could be getting caught up in the outflow.à COS observations also reveal that the clouds of gas contain the elements silicon, carbon, and aluminum.à These are produced inside stars.à Does this mean that star formation or star death is involved in the original event that formed the bubbles? Astronomers think that one possible cause for the outflows is a star-making frenzy near the galactic center. Eventually, those hot, young massive stars die in supernova explosions, which blow out gas. If a lot of them exploded at once, it might spur the formation of a huge gas bubble.à Another scenario has a star or a group of stars falling onto the Milky Ways supermassive black hole. When that happens, gas superheated by the black hole blasts deep into space and that could be what filled out the bubbles.à Those bubbles are short-lived compared to the age of our galaxy (which is more than 10 billion years old). Its possible that these arent the first bubbles to billow out from the core. It could have happened before.à Astronomers will continue to look at these bubbles using distant quasars as illuminators, so it might not be too long before we hear just what it was that caused a huge commotion at the heart of the Milky Way Galaxy.à They may well also be interested in studying smaller such bubbles that form as a result of supernova explosions and the actions of hot young stars. Such bubbles actually work to protect systems encased within. One example is the Local Interstellar Cloud, which encases the solar system today. In a few tens of thousands of years, the Sun and planets will move outside of it, exposing our system to radiation levels it hasnt experienced for a long time.

The Terrorist Group (ISIS) Research Paper Example | Topics and Well Written Essays - 3250 words
The Terrorist Group (ISIS) - Research Paper Example ed condemnation for their ideologies and principles from all around the world, and especially from the Muslim community, which believes that this group does not represent the faith that is Islam. This paper will take a closer look at the group, and examine the principles that make it such a threat to the freedom and liberties of all people. According to different sources, this group was initially a part of the main group al-Qaeda, but their involvement in the Syrian war made them change their name from ISI (Islamic State of Iraq) to ISIL or ISIS (Islamic State of Iraq and the Levant). In 2014, the group sought to change their name to Islamic State, and proclaimed their organization to be a worldwide caliphate. This prompted criticism from different governments, Muslim leaders, and the United Nations calling out the leader of the group and refusing to acknowledge the power the group claims to have over all Muslims, their states, organizations, and even the different religious groups in the world (Tran and Weaver 1). The presence of the Islamic State in some of the warring countries is something that is quite disheartening. It is their ideologies and principles that make them a particularly cruel and calculating group of extremists. Their thoughts on what is right and wrong may be the key to unlocking some of the thoughts they have on the people they unleash terror upon, and the reason why they are becoming intolerable even to their Muslim folk (Crooke 1). It is this form of cruelty that begs the question as to whether this group is motivated by religious beliefs, or if the group has other underlying agendas. The criticism they have received seems to have no impact on their actions as more people continue to suffer at the hands of the Islamic State (IS) organization. Women, who speak out against the organization, continue to be enslaved as they are used by the fighters in the group for gratification. The young are sold off to become the fightersââ¬â¢ wives, while

Solid State Physics Essay Example | Topics and Well Written Essays - 2250 words
Solid State Physics - Essay Example The models apply varied scientific principles in exploring the dislocation dynamics of semiconductors. In all the models, nucleation and propagation occur in successions. Dislocation in semiconductors is affected by factors like changes in temperatures and the presence of impurities. Dislocation dynamics is responsible for the plastic and ductile nature of most semiconductors. Dislocation is an important aspect in the physics of materials and requires extensive research. Dislocations dynamics is significant in the physics (mechanical and electrical) of semiconductors. Dislocations carry plasticity along crystalline elements. Moreover, the dislocations form centers that trap and scatter electronic carriers. Numerous experimental information regarding the dislocation dynamics of semiconductors that are tetrahedral bonded are available in various research articlesi. The principal slip systems for silicon are the 60Ã °, while the orientation of the screw dislocations falls along the slip planeii. The two systems form a slithered configuration and dissociate to form pairs of fractional dislocations that bound ribbons of inherent stacking faultiii. Dissociations reduce the energy utilized in strain. Moreover, the lower the energy of the stacking faults, the more favorable the dislocations occur, energetically. The theory holds for semi-conductors (III-V and II-VI) and germanium. Thin films semiconductors are an engineering marvel in the contemporary science world. For instance, the polycrystalline thin films that have reduced defect concentration are omnipresent to contemporary engineeringiv. The reduced defect concentration facilitates the processingv. In conjunction with curiosity in scientific practices, many applications trigger intensive research of the procedures involved in the processing of polycrystalline (semi-conductor) thin films. Typical examples of compounds with polycrystalline thin films include copper and
