The Rise Of The Nuclear Weapon Into A Political Weapon Essay -- essays

During last 50 years of development, the nuclear bomb, as the ultimate weapon became the peacekeeping force on the earth. The nuclear bomb was developed in Manhattan project during the WW II and was successfully tested in the New Mexico on July 16 1945. At this point started the change of nuclear weapon from ultimate weapon to political weapon. USA decided to use the atomic bomb to defeat Japan in order to save around 500.000 lives of American soldiers that were needed to end the war and in the summer 1945 the USA dropped two bombs on Hiroshima and Nagasaki. The nuclear weapon raised the confidence of USA but president Truman did not ordered its mass production because at that time he saw no explicit political function for the bomb. USA even tried to internationalize control of the bomb under the UNITED NATIONS but the Soviets were reluctant to support American plan for two reasons. To stop soviet nuclear program before developing the first soviet bomb would give Americans permanent lead in nuclear weapons technology. Soviets believed that instruments of force always have political capabilities. For the Kremlin weapons were political tools. This led Americans to the same conclusion. The beginning of Cold War created several political functions of nuclear weapons: nuclear deterrence, alliance building, and international prestige. The Nuclear Bomb was developed as the weapon of war at the end of the Second World War. Nuclear Deterrence was than the natural function of nuclear bomb. The atomic bomb had a function of â€Å"natural deterrence† at the early beginning of Cold War when Soviets did not have nuclear weapons. The Soviets would not attack West Europe because they would risk war with USA and USA had atomic bomb that was seen by Soviets as the essence of deterrence. USA also believed that if Soviets finish their own bomb they would not be deterred by USA and its nuclear arsenal therefore the West Europe would become vulnerable. After the Soviets detonated its own bomb in September 1949, the Truman administration abandoned its policy of natural deterrence and ordered the development of more powerful hydrogen thermonuclear bomb. Since Soviet nuclear bombs deterred US deterrence, Truman sought a way to restore deterrence. He ordered a study by the Department of State’s policy planning staff and the result, NATIONAL SECURITY COUNCIL PAPER 68 (NSC-68), went to Tru... ...r weapons that would give him the leadership in Arab world and he could organize and lead an alliance against Israel. The increasing proliferation of nuclear technology in areas of simmering regional conflicts increases the probability of nuclear war. During the 50 years of existence, the real function of nuclear power was changed from direct use as a weapon of war through deterrence tool to the ticket to nuclear club that means the sing of superpower.

Peer and Self Assessment

Assessing Learning Peer and Self Assessment Peer Assessment One of the ways in which students internalize the characteristics of quality work is by evaluating the work of their peers. However, if they are to offer helpful feedback, students must have a clear understanding of what they are to look for in their peers' work. The instructor must explain expectations clearly to them before they begin. One way to make sure students understand this type of evaluation is to give students a practice session with it. The instructor provides a sample writing or speaking assignment. As a group, students determine what should be assessed and how criteria for successful completion of the communication task should be defined. Then the instructor gives students a sample completed assignment. Students assess this using the criteria they have developed, and determine how to convey feedback clearly to the fictitious student. Students can also benefit from using rubrics or checklists to guide their assessments. At first these can be provided by the instructor; once the students have more experience, they can develop them themselves. An example of a peer editing checklist for a writing assignment is given in the popup window. Notice that the checklist asks the peer evaluator to comment primarily on the content and organization of the essay. It helps the peer evaluator focus on these areas by asking questions about specific points, such as the presence of examples to support the ideas discussed. For peer evaluation to work effectively, the learning environment in the classroom must be supportive. Students must feel comfortable and trust one another in order to provide honest and constructive feedback. Instructors who use group work and peer assessment frequently can help students develop trust by forming them into small groups early in the semester and having them work in the same groups throughout the term. This allows them to become more comfortable with each other and leads to better peer feedback. Self Assessment Students can become better language learners when they engage in deliberate thought about what they are learning and how they are learning it. In this kind of reflection, students step back from the learning process to think about their language learning strategies and their progress as language earners. Such self assessment encourages students to become independent learners and can increase their motivation. The successful use of student self assessment depends on three key elements:  ·Goal setting  ·Guided practice with assessment tools  ·Portfolios Goal setting Goal setting is essential because students can evaluate their progress more clearly when they have targets against which to measure their performance. In addition, students' motivation to learn increases when they have self-defined, and therefore relevant, learning goals. At first, students tend to create lofty long-range goals (â€Å"to speak Russian)† that do not lend themselves to self assessment. To help students develop realistic, short-term, attainable goals, instructors can use a framework like SMART goals outline shown in the popup window. One way to begin the process of introducing students to self-assessment is to create student-teacher contracts. Contracts are written agreements between students and instructors, which commonly involve determining the number and type of assignments that are required for particular grades. For example, a student may agree to work toward the grade of â€Å"B† by completing a specific number of assignments at a level of quality described by the instructor. Contracts can serve as a good way of helping students to begin to consider establishing goals for themselves as language learners. Guided practice with assessment tools Students do not learn to monitor or assess their learning on their own; they need to be taught strategies for self monitoring and self assessment. Techniques for teaching students these strategies are parallel to those used for teaching learning strategies (see Motivating Learners[->0]). The instructor models the technique (use of a checklist or rubric, for example); students then try the technique themselves; finally, students discuss whether and how well the technique worked and what to do differently next time. In addition to checklists and rubrics for specific communication tasks, students can also use broader self-assessment tools to reflect on topics they have studied, skills they have learned, their study habits, and heir sense of their overall strengths and weaknesses. An example of such a tool appears in the popup window. Students can share their self-assessments with a peer or in a small group, with instructions that they compare their impressions with other criteria such as test scores, teacher evaluations, and peers' opinions. This kind of practice helps students to be aware of their learning. It also informs the te acher about students' thoughts on their progress, and gives the teacher feedback about course content and instruction. Portfolios Portfolios are purposeful, organized, systematic collections of student work that tell the story of a student's efforts, progress, and achievement in specific areas. The student participates in the selection of portfolio content, the development of guidelines for selection, and the definition of criteria for judging merit. Portfolio assessment is a joint process for instructor and student. Portfolio assessment emphasizes evaluation of students' progress, processes, and performance over time. There are two basic types of portfolios:  ·A process portfolio serves the purpose of classroom-level assessment on the part of both the instructor and the student. It most often reflects formative assessment, although it may be assigned a grade at the end of the semester or academic year. It may also include summative types of assignments that were awarded grades.  ·A product portfolio is more summative in nature. It is intended for a major evaluation of some sort and is often accompanied by an oral presentation of its contents. For example, it may be used as a evaluation tool for graduation from a program or for the purpose of seeking employment. In both types of portfolios, emphasis is placed on including a variety of tasks that elicit spontaneous as well as planned language performance for a variety of purposes and audiences, using rubrics to assess performance, and demonstrating reflection about learning, including goal setting and self and peer assessment. Portfolio characteristics:  ·Represent an emphasis on language use and cultural understanding  ·Represent a collaborative approach to assessment Represent a student's range of performance in reading, writing, speaking, and listening as well as cultural understanding  ·Emphasize what students can do rather than what they cannot do  ·Represent a student's progress over time  ·Engage students in establishing ongoing learning goals and assessing their progress towards those goals  ·Measure each student's achievement while allowing for individu al differences between students in a class  ·Address improvement, effort, and achievement  ·Allow for assessment of process and product  ·Link teaching and assessment to learning [-;0] – http://www. nclrc. org/essentials/motivating/moindex. htm

Book Review The Prince Essay - 1014 Words

This semester in Mr. Sellers’ History class, we were asked to read a history novel and write a book review on it. I chose to read The Prince by Niccolo Machiavelli, and it sure did not disappoint. For a book on history, it was not so bad. The two parts to this review include a summary and a critical analysis. This paper will discuss the major points Machiavelli made in his book and analyze his tone and writing style, with an overall critique. The Prince is a novel written in 1513 by Niccolo Machiavelli. This book contains 26 chapters, focusing on acquiring and maintaining political power. In other words, it could be seen as the â€Å"do’s and don’ts† of the political world. In Chapters One through Eleven, the author discusses the different†¦show more content†¦Auxiliaries are just as unreliable and dangerous as the mercenaries, but they are loaned to a ruler from others. The most desirable troops are the natives, the citizens and subjects. Mixed troops are less desirable than fully native troops because they are a mixture of natives and mercenaries or auxiliaries. These descriptions are accompanied by examples to help the reader better understand the roles different types of troops served and how effective each type was for the rulers mentioned. Machiavelli goes on in Chapters Fifteen through Twenty Three to discuss his advice to the reader in the ideal behavior and characteristics of a prince. He mentions that doing good would only lead to the ruin of a prince’s kingdom. He claims that a prince should be stingy and cruel as opposed to generous and merciful. He then, of course, adds in examples of successful rulers who were both moral and immoral alike. A prince should break promises more than he keeps them, according to the author. He also suggests that, while behaving in the aforementioned ways, a prince should do his best to avoid being despised by leaving his subjects’ land and women alone and by undertaking great projects to boost his reputation. As suggested at the beginning of Chapter Nineteen, a prince should not be â€Å"fickle, frivolous, effeminate, cowardly, [or] irresolute,† (70).  ¬Ã‚ ¬Ã‚ ¬He should also choose wise, as opposed to flattering, advisors.
