3.2 Essay Questions

1) Why are foreign currency futures contracts more popular with individuals and banks while foreign currency forwards are more popular with businesses?

Answer: Foreign currency futures are standardized contracts that lend

themselves well to speculation purposes but less so for hedging purposes. The standardized nature of the futures contract makes it easy to trade futures and to make bets about general changes in the value of currencies. Forward contracts are better for hedging in that they are tailored to meet the specific needs of the client, typically a business, and can be quite useful in reducing exchange rate risk. Banks are involved in the foreign currency futures market in part to offset positions that they may have taken in the forward markets as dealers.

2) How do currency forward and futures contracts differ with respect to maturity, settlement, and the size and timing of cash flows?

Answer: see p36-37, Table 3.7

3) What is the primary role of the exchange clearinghouse?

Answer: see p14-15

※4) Draw and explain the payoff profile associated with a currency futures contract.

Answer: refer to chapter 8

最新现代移动通信-蔡跃明-第三版思考题与习题参考答案-chapter-3

第三章 思考题与习题 1. 组网技术包括哪些主要问题？ 答：（1）干扰对系统性能的影响； （2）区域覆盖对系统性能的影响； （3）支撑网络有序运行的要素； （4）越区切换和位置管理； （5）无线资源的有效共享。 2. 为何会存在同频干扰？同频干扰会带来什么样的问题？ 答：同频干扰是指所有落在接收机通带内的与有用信号频率相同的无用信号的干扰，这些无用信号和有用信号一样，在超外差接收机经放大、变频而落在中频通带内，接收系统无法滤出无用信号，从而产生同频干扰。 同频干扰会带来的问题：影响链路性能、频率复用方案的选择和系统的容量限制等问题 3. 什么叫同频复用？同频复用系数取决于哪些因素？ 答：在移动通信系统中，为了提高频率利用率，在相隔一定距离以外，可以使用同的频率，这称为同频复用。 影响同频复用系数的因素有：一个区群（簇）中小区的个数（区群的大小），小区的大小，形状等。 4. 为何说最佳的小区形状是正六边形？ 答：小区形状的设计要求：小区无空隙、无重叠的覆盖整个服务区域。 全向天线辐射的覆盖区为圆形，不能无空隙、无重叠的覆盖整个区域。在考虑交叠之后，实际上每个辐射区的有效覆盖区是一个多边形。满足无空隙、无重叠条件的小区形状有三种：正三角形、正方形和正六边形。而在服务区面积一定的情况下，正六边形小区的形状最接近理想的圆形，用它覆盖整个服务区所需的基站数最少，也就最经济。 5. 证明对于六边形系统，同频复用系数为22Q N i j ij ==++。 证明：同频复用系数Q 的定义为在同频些小区距离)(D 与小区半径)(R 的比值。 同频小区的距离也就是两个同频小区的中心距离，对于正六边形系统它是这样确定的，从一个小区的中心出发，沿着一边的中垂线数i 个小区，在向顺时针转060再向前数j 个小区，起点和终点的两个小区的距离就是同频小区的距离。由余弦定理可得 R ij j i D )(322++=，又因为ij j i N ++=22 所以N R R N R D Q 33=== 即得证。 6. 设某小区移动通信网，每个区群有4个小区，每个小区有5个信道。试用分区分组配置法完成群内小区的信道配置？（见书上15，16页和6页）

信息技术课外活动总结

信息技术兴趣小组活动总结当前我们处于二十一世纪，人类已步入信息社会时代。计算机作为信息处理的工具，广泛地应用于我们生活的各个方面。为适应时代的发展，计算机课程已被纳入到各级学校必修课程之中。为了适应现代教育形势发展的要求，为了充分培养学生的能力，促进学生的特长与能力协调发展，本学期我校将开展信息技术兴趣小组活动，并努力提高活动质量，使学生学有所得，学有所长。 一．活动措施 1、做好报名工作 先初步设定信息技术活动兴趣小组人数约16人左右，由各班主任利用班会做好宣传发动工作，让学生自由报名，学校再根据各班得报名人数从中选出16名个具有一定计算机基础的学生作为学员（要求为三至六年级），活动地点为学校计算机教室，时间为每周三下午第三节。 2、加强管理 为能更好地完成课外活动的学习目标，必须做到认真备课，耐心辅导，全面关心爱护学生，管理组织教育好学生遵守学生日常行为规范，文明守纪，讲究卫生，更要爱护来之不易的计算机设备。 3、重视计算机引言课的教学，培养学生的学习兴趣 学习兴趣是学生基于自己的学习需要而表现出来的一种认识倾向，它是学好一门课的内驱动力。俗话说：“良好的开端是成功的一半。”这就要求我们在计算机引言课中，要从计算机的产生、发展、最新动态和Internet网络的有关常识的介绍，同时结合本地区、本校利用计算机进行画图、制作学校网页等方面的应用，最大限度地让学生了解到计算机的重要作用，学习计算机的基础知

识和技能是时代的需要，也是个人成才的需要，激发他们的求知欲望，充分调动学生的学习积极性。 4、注重上机操作能力，使学习兴趣持久不息 计算机学科是一门实践操作极强的学科，应该说上机时间占70%，理论课只占30%。学生上机操作的过程是一个融阅读、理解思考和观察、验证于一体的过程。学生刚开始学习时还有兴趣，但慢慢地对计算机的热情就会下降，不感兴趣。这就要求我们教师在上课过程中采用“任务驱动”教学法，明确每节课的教学目标，设下疑难问题，让学生自己去思考问题、上机实践探索解决问题的办法，给学生“主动发展”的空间，大力推行“发现式”教学，同时要保证学生充裕的上机时间，着重培养和锻炼学生的操作技能。当学生通过自己的上机操作能够解答某一问题，必将会熟练掌握该项操作技能，增添一份喜悦之情，充满一股学习计算机的热情。如在讲解文件、文件夹的基本操作时，由于这节内容相当重要，而且实践性非常强，教师可以先围绕教学目标出几道练习题，让学生自己带着问题操作预习，然后教师再总结学生的学习情况。同时不定期地开展一些全体学生都参加的指法练习、编辑排版等操作竞赛，让学习兴趣持久不息。 5、发挥“小老师”的作用，激发学习兴趣 学生当“小老师”改变了传统的师生间单向传递知识的方式，使学生由知识的被动接受者转变为知识的传授者，发挥了学生的主体作用。我们对教学中的一些简单知识内容，而且是学生最感兴趣的内容，如在“画图”的教学中，事先告诉学生教学目标，让学生自己组织上课，学生就会按照自己的理解程度，以自己最好的教学方式，扮演“小老师”。同时，在上机实践课中，教师由于各种

Chapter 3 Using costs in decision making 1 How Management accounting supports internal decision making ●Pricing-market-determined price, cost plus pricing. ●Product Planning-target costing. ●Budget ●Performance ●Contracting-In cost reimbursement contracts organizations are reimbursed their cost plus anincrement for the goods or service they provide under the contract. 2 Variable and fixed costs Variable cost-A variable cost is one that increases proportionally with changes in the activity levelof some variable. Variable cost =Variable cost per unit of the cost driver *Cost driver units. Fixed cost-A fixed cost is a cost that does not vary in the short run with a specified activity. Total cost =Variable cost +Fixed cost 3 Cost- Volume –Profit Analysis Agood understanding of cost and revenue behavior is critical in providing decisionmakers with an understanding of the relationship betwe en a project’s revenues, costs,and profits. Profit =Revenue -Total costs =Revenue -Variable costs -Fixed costs 4 Developing and Using the CVP equation The difference between total revenue and total variable cost is called the contribution margin. The contribution margin per unit is the contribution that eachunit makes to covering fixed costs and providing a profit. Profit =Unit sales *(Price per unit $ Variable cost per unit)-$ Fixed costor Profit =Contribution margin per unit *Units produced and sold-Fixed costs units needed to be sold =(target profit + fixed cost) /contribution margin per unit 5 Other useful cost definitions Mixed cost- A mixed cost is a cost that has a fixed component and a variable component. Step variable costs- A step variable cost increases in steps as quantity increases. Incremental cost -An incremental cost is the cost of the next unit of production and is similar to the economist’s notion of marginal cos t. Sunk cost- A sunk cost is a cost that results from a previous commitment and cannot berecovered. Relevant cost-A relevant cost is a cost that will change as a result of some decision.

小学信息技术课外活动计划

第十一小学信息技术课外活动计划 2013年秋 一、指导思想： 信息技术兴趣小组，作为学校和信息技术教育有机结合的典型载体之一，随着社会需要应运而生，并在深化教育改革获得长足发展，愈益生动显示其活力，成为素质教育的重要方面。信息技术涉及的面广，能培养学生多方面的才能。因此，结合我校的情况，开展了一个信息技术兴趣小组，希望通过这一个小组能激发学生的创作兴趣，提高他们的创新能力。 二、具体工作： 这一学期我们将进行以下几个方面的学习： 1、电脑绘画 电脑绘画是在传统绘画基础上发展起来的一门新兴绘画艺术。一方面。它继承了传统绘画艺术的基本特点，如构图、造型、着色等；另一方面，它具有传统绘画艺术所无法比拟的优越性，如它的方便易用、新颖独特以及效果的丰富多样等。因而，电脑绘画深受小学生的喜爱。这是一种科学与艺术相结合的教学手段，它以生动的形式，事半功倍的效果，在我们眼前展示了一幅诱人的美术教学前景。这学期主要教学画图软件和金山画王。 2、制作电子报刊 辅导学生学会使用WORD软件，并运用WORD软件，由自命一个自己专注的题目，围绕这一题目，收集、整理相关信息，并在认真学习和研究相关信息的基础上，参照电子出版物的有关标准，以适当形式创作的电子报或电子刊物。主要教学WORD。 3、中英文打字 根据小学阶段信息技术的教学目标和任务，按省的基本要求，小学阶段应当学会使用键盘打字。而中文输入时的教学提倡采用拼音输入。学习中英文打字能促进信息技术与英语、语文教学的整合，并针对小学生特点将使这项活动更有意义，为它的健康深入开展提供保障。 4、幻灯片制作

Powerpoint和Word、Excel等应用软件一样，都是Microsoft公司推出的O ffice系列产品之一。PowerPoint是制作和演示幻灯片的软件，主要用于演示文稿的创建，即幻灯片的制作，可有效帮助演讲、教学，产品演示等，它能够制作出集文字、图形、图像、声音以及视频剪辑等多媒体元素于一体的演示文稿，把自己所要表达的信息组织在一组图文并茂的画面中，用于介绍公司的产品、展示自己的学术成果。用户不仅在投影仪或者计算机上进行演示，也可以将演示文稿打印出来，制作成胶片，以便应用到更广泛的领域中。利用Powerpoint不仅可以创建演示文稿，还可以在互联网上召开面对面会议，远程会议或在网上给观众展示演示文稿。 本学期以以学习和掌握制作Powerpoint的基本方法和基本理论为目的，培养学生对计算机的兴趣，启迪思维、发展能力。主要教学制作幻灯片的过程。 5、Flash制作 Flash是美国Macromedia公司所设计的一种二维矢量动画软件。通常包括M acromedia Flash，用于设计和编辑Flash文档，以及Macromedia Flash Playe r，用于播放Flash文档。Flash 是一种创作工具，设计人员和开发人员可使用它来创建演示文稿、应用程序和其它允许用户交互的内容。Flash 可以包含简单的动画、视频内容、复杂演示文稿和应用程序以及介于它们之间的任何内容。通常，使用 Flash 创作的各个内容单元称为应用程序，即使它们可能只是很简单的动画。您也可以通过添加图片、声音、视频和特殊效果，构建包含丰富媒体的 Flash 应用程序。 Flash制作能推动信息技术课程的深入实施，丰富学生的课外活动，激发学生学习电脑的兴趣。学生在制作Flash动画创建、制作、生成动画的方法，充分发挥学生的创新意识，实践制作由简单动画——特效动画——复杂动画——交互式动画的全过程，并利用知识的迁移，培养学生发现问题、分析问题、解决问题的实际能力。

Morphology studies the internal structure of words and the rules by which words are formed. 2.Words are the smallest meaningful units of language. 3. Just as a phoneme is the basic unit in the study of phonology, so is a morpheme the basic unit in the study of morphology. 4. The smallest meaningful units that can be used freely all by themselves are free morphemes. 5. Bound morphemes include two types: roots and affixes. 6. Inflectional morphemes manifest various grammatical relations or grammatical categories such as number, tense, degree, and case. 7.
