1Introduction

In the last two decades,information systems(IS)manage-ment decision making has become more complex.Every-day,IS managers in organizations of all over the world manage billions dollars of assets and must make complex decisions that involve information security,outsourcing, disaster recovery,software,hardware and vendor selection, investment strategies,timing the implementation of com-plex software systems(such as enterprise resource planning (ERP)).Inadequate understanding of these decision prob-lems,poor decision analysis,and bad judgment can result in catastrophic outcomes for companies.However,there has been limited research on decision models and frame-works that could assist information technology(IT) managers with these complex decision problems.While there are researchers working in these areas,much of their work appears in journals outside the field of IS.The primary objective of this special issue of Information Systems Frontiers is to focus on providing solutions to significant IS management problems and to provide strategic knowledge for practicing managers.A second objective of this special issue to give impetus to the development of a line of research that would continue to focus attention on providing solutions for the many emerging complex problems that IS managers may face. 2Information systems decision context

Information systems management decision problems such as information security,outsourcing,disaster recovery, software,hardware and vendor selection,investment strat-egies,timing the implementation of complex software systems(such as ERP)are extremely complex and can adversely impact the performance of the firm.The complexity of these decision problems derive from organi-zation and environmental conditions that include(a) multiple stakeholders with different goals and risk prefer-ences(b)multiple objectives and value trade-offs;(c) competitive environments with risk and uncertainty;and (d)inter dependencies,indefinite time horizons and strategic impacts of decision.Under these conditions decision makers often have difficulties identifying decision alternatives and must be creative and careful in their analysis,as the consequences of poor IS decision making found in the literature show(Lyttinen and Robey1999;Yeo 2002;Ngwenyama et al.2007).When managers face complex IS problems,decision analysis frameworks and methods can be extremely useful when they assist:(1) interrogating the problem domain;(2)structuring decision problems and generating alternatives;(3)analyzing alter-natives and assessing their impacts;(4)determining the preferences of decision makers;(5)evaluating and com-paring decision alternatives,and,analysis of implications. However,while general theories and frameworks exists for decision analysis,the complexity and diversity of IS problems necessitate research and development of frame-

works and models specific to the class of decision problems that IS managers face.

3The papers

In this special issue we present eight papers that present a range of approaches and address a wide range of IS decision problems.In general the papers can be classified into two categories,frameworks for decision analysis and decision models.One of the papers presents a conceptual framework;five of the papers present structured decision analysis frameworks,and three present decision-theoretic based models.While all the papers follow the design science paradigm of research,the decision framework papers present empirical cases,and the decision-theoretic papers present demonstrations of analysis using the models.

The Samoilenko paper(Information Systems Fitness and Risk in IS Development:Insights and Implications from Chaos and Complex Systems Theories)outlines a framework and principles for analyzing IS fitness and risk based on chaos and complexity theory.Samoilenko approach is more in the tradition of appreciative decision making,where the focus is on ways of thinking to help the decision maker appreciate the problem situation.Aydin and Bakker(Analyzing IT Maintenance Outsourcing Decision from a Knowledge Management Perspective)also follow this tradition but from an empirically grounded perspective outlining a framework for decision analysis of knowledge management issues in IS outsourcing.They focus mainly on strategies for interrogating the problem domain and structur-ing the decision problem.Alaranta and Henningsson(An Approach to Analyzing and Planning Post-Merger IS Integration:Insights from Two Field Studies)outline a framework and approach for post-merger information sys-tems integration planning.Post-merger IS integration is a complex multidimensional problem that is challenging many IS managers.Alaranta and Henningsson discuss the key decisions of the planning process and suggest strategies for approaching them.An important feature of their approach is its grounding in empirical case studies of favorable and unfavorable strategies.The Scheepers and Scheepers(A Process-focused Decision Framework for Analyzing the Business Value Potential of IT Investments)framework focuses on analyzing IT investments from the perspective of business value creation.These authors develop a model for exploring the business value potential of IT at the business process level;a challenging undertaking necessary for cost-benefit analysis.The last of this category is that of Barclay(Towards An Integrated Measurement of IS Project Performance:The Project Performance Scorecard),who presents a framework and approach for evaluating project performance based on existing theoretical models of IS success and the Balanced Scorecard.She focuses on defining dimensions of project measurement that are of interest to different stakeholders and a process for eliciting preferences.

The three decision-theoretic papers also vary in topics that they cover.Like Barclay,Plaza(Team Performance and Information System Implementation Application of the Progress Curve to the Earned Value Method in an Information System Project)is concerned with IS project performance but comes to the issue from a different perspective.Plaza is interested in predicting implementa-tion times(and cost)for large scale IS projects and proposes a decision model based on the earned value method and the learning curve.Rao and Osei-Bryson(An Approach for Incorporating Quality-Based Cost–Benefit Analysis in Data Warehouse Design)focus on an aspect of data warehouse design where the major concern is the determination of the data that are to be produced and stored in the data warehouse.They present a cost-benefit model that incorporates quality issues in data warehouse design. Finally Turetken(Is Your Back-Up IT Infrastructure in a Safe Location?)presents a multi-criteria decision model for location of the IT infrastructure for business continuity planning.

4Contribution of this issue

This issue of ISF makes a contribution to theory and practice of IS management from the following perspectives:(1)The papers present frameworks and models that have immediate application to various classes of IS decision problems.(2) The papers present possibilities for further research into decision models for the problems that the authors have addressed.However,this research can evolve along different lines:(a)the development of decision support systems for the addressed problems;(b)other approaches or techniques that might be applicable for extending the breadth and depth of the current approaches;(c)alternative approaches can be proposed for the set of problems and comparative analysis can be conducted.

We wish to express our appreciation to all the authors who submitted papers.We also wish to express our gratitude to all the reviewers who diligently reviewed the papers in order to ensure that that there was appropriate quality and fit. References

管理信息系统MIS(Management Information System)

MIS(Management Information System) the term in the interest of the administration. In the wake of the development of MIS, much business sit up the decentralized message concentration to establish the information system ministry of directly under director, and the chief of information system ministry is ordinarily in the interest of assistant manager’s grade. After the authority of business is centralized up high-quality administration personnel staff’s hand, as if causing much sections office work decrease, hence someone prophesy, middle layer management shall vanish. In reality, the reappearance phase employed layer management among the information system queen not merely not to decrease, on the contrary there being the increase a bit. This is for, although the middle layer management personnel staff getting off exonerate out through loaded down with trivial details daily routine, yet needs them to analyses researching work in the way of even more energy, lift further admonishing the decision of strategic importance level. In the wake of the development of MIS, the business continuously adds to the demand of high technique a talented person, but the scarce thing of capability shall be washed out gradually. This compels people by means of study and cultivating, and continuously lifts individual’s quality. In The wake of the news dispatch and electric network and file transmission system development, business staff member is on duty in many being living incomparably either the home. Having caused that corporation save the expenses enormously, the work efficiency obviously moves upward American Rank Zeros corporation the office system on the net, in the interest of the creativity of raise office personnel staff was produced the advantageous term. At the moment many countries are fermenting one kind of more well-developed manufacturing industry strategy, and become quickly manufacturing the business. It completely on the basis of the user requirement organization design together with manufacture, may carry on the large-scale cooperation in the interest of identical produce by means of the business that the flow was shifted the distinct districts, and by means of the once more programming to the machinery with to the resources and the reorganization of personnel staff , constituted a fresh affrication system, and causes that manufacturing cost together with lot nearly have nothing to do with. Quickly manufacturing the business establishes a whole completely new strategy dependence relation against consumer, and is able to arouse the structure of production once more revolution. The management information system is towards the self-adoption and Self-learning orientation development, the decision procedure of imitation man who is be able to be better. Some entrepreneurs of the west vainly hope that consummate MIS is encircles the magic drug to govern the business all kinds of diseases; Yet also someone says, and what it is too many is dependent on the defeat that MIS be able to cause on the administration. It is adaptable each other to comprehend the effect to the business of MIS, and is favor of us to be living in development and the research work, and causes the business organization and administer the better development against MIS of system and administration means , and establish more valid MIS. 英文翻译文章的出处：Russ Basiura, Mike Batongbacal 管理信息系统: 管理信息系统就是我们常说的MIS(Management Information System), 在强调管理，

数据库管理系统在信息管理中的作用

数据库管理系统在信息管理中的作用 一信息管理系统与数据库管理系统概述 管理信息系统(Management Information System)系统，是一个以人为主导，利用计算机硬件、软件及其它办公设备进行信息的收集、传递、存贮、加工、维护和使用的系统。管理信息系统是进行有效管理、正确决策和实现管理现代化的重要手段。作为一门新兴学科，管理信息系统综合了管理科学与工程、计算机科学、经济理论、统计学和运筹学等许多学科的概念和方法，形成了独特的体系和领域。自20世纪40年代以来，信息技术经过60余年的高速发展，受益最多的就是管理和经济领域，特别是促进了电子商务、电子政务、数字图书馆等工程的极大发展和社会的进步。 完善的管理信息系统具有以下四个标准：确定的信息需求、信息的可采集与可加工、能够经过程序为管理人员提供信息、能够对信息进行管理。其中具有统一规划的数据库是管理信息系统成熟的重要标志。

数据库是储存在计算机内的数据的集合。数据库存放数据是按数据所提供的数据模式存放的，它能构造复杂的数据结构以建立数据间的内在联系与复杂联系，从而构成数据的全局结构模式。数据库中的数据按一定的数据模型组织、描述和储存，具有较小的冗余度、较高的数据独立性和易扩展性，并可为各种用户共享。 数据库管理系统是用于管理和维护数据的系统软件。它是位于用户与操作系统之间的数据管理软件。数据库管理系统具有数据定义功能、数据组织功能、数据存储和管理功能、数据操纵功能、数据库的事物管理功能、运行管理功能、数据库的建立和维护等功能。 数据库系统由以下几部分组成：数据库(数据)、数据库管理系统(软件)、数据库管理员(人员)、系统硬件平台(硬件)、系统软件平台(软件)组成。这五个部分构成了以数据库为核心的完整的运行实体，称为数据库系统。有时也把数据库系统简称为数据库。 数据库是信息管理的最新技术，是计算机科学的重要分支。二十余年来，数据库管理系统已从专用的应用程序包发展成为通用的系统软件。由于数据库具有数据结构化、最低冗余度、较高的程序与数据独立性、易于扩充、易于编制应用程序等优点，较大的信息管理系统都是建立在数据库设计之上的。因此，不但大型计算机及中小型计算机、甚至微型机都配有数据库管理系统。二信息管理中应用数据库管理系统所起的作用

管理信息系统第二专业重点答案

管理信息系统（第五版） 第一章信息系统和管理 复习思考题参考答案或提示 1.1 什么是信息？信息和数据有何区别？ [答] 信息是经过加工以后、对客观世界产生影响的数据。信息的概念不同于数据。数据（Data，又称资料）是对客观事物记录下来的，可以鉴别的符号。数据经过处理仍然是数据。处理数据是为了便于更好的解释。只有经过解释，数据才有意义，才成为信息。同一数据，每个人的解释可能不同，其对决策的影响可能不同。决策者利用经过处理的数据做出决策，可能取得成功，也可能得到相反的结果，这里的关键在于对数据的解释是否正确，因为不同的解释往往来自不同的背景和目的。 1.4 什么是信息技术？信息技术在哪些方面能给管理提供支持? [答] 凡可以扩展人的信息功能的技术都是信息技术，如计算机技术、通信技术、传感技术等。通常，信息系统技术就是指计算机系统技术、通信系统技术，以及它们组成的系统的技术。这些技术从以下几方面给管理提供支持： 1. 作为工具提高数据处理、事务处理的效率； 2. 支持决策过程，如决策支持系统； 3. 支持战略管理，提高竞争优势； 4. 作为驱动力推进管理变革，如流程重组，组织结构向扁平化发展等。 1.7 试述信息系统对人类生活与工作方式的有利和不利影响。

[答] 信息系统会改变人类的工作性质。例如，信息系统使中下层管理人员从繁琐的事务性工作中解脱出来，使他们在工作中有更多的精力考虑管理中的重要问题，能更充分地发挥自己的作用。他们可以在自己的终端上，通过计算机网络来获得更充分的信息，利用微型机解决要处理的问题，甚至就在家中上班；电子商务的发展使人们的消费观念和行为都发生变化，这不仅降低了交易费用和物流成本，而且进一步提高了个性化服务的水平。另一方面，信息系统正在进一步向家庭、教育和娱乐方面渗透，这些都使人们的生活变得更加方便，更加丰富多彩。 信息系统作为一种信息收集、加工、存储、传递和提供信息的工具，和任何工具一样，有可能带来有利的一面，也可能带来不利的一面，关键在于如何使用。以网上信息传播为例。利用网络，特别是通过Internet建立教育网站、虚拟图书馆等为广大用户提供了丰[富的教育资源共享，但另一方面，网上宣传凶杀、色情等有害的信息却对人们产生负面的影响。解决这些问题需要政府和社会各界采取切实措施，予以取缔和制裁，并通过各种方法加强和改进教育工作。 第二章管理信息系统概论 复习思考题参考答案或提示 2.2从层次上划分，MIS可分为哪几类？从系统功能和服务对象划分又如何呢？ [答] 从层次上划分，MIS可以分为业务信息系统、管理信息系统和决策支持系统。从系统的功能和服务对象上划分，MIS可分为国家经济信息系统、企业管理信息系统、事务型管理信息系统、行政机关办公型管理信息系统和专业型管

一、选题背景 1.1论坛管理信息系统发展的学科背景 管理信息系统的产生是管理科学和相关学科发展的必然结果。管理信息系统服务于管理工作，管理信息系统的对象是管理工作者。管理工作是通过使用一定的理论、方法和技术，合理地计划、组织、控制、协调和调度各种所需的资源，如人力资源、财物资源、技术资源和信息资源等，以最小的投入实现某种预定的目标。管理活动的核心是计划和控制工作。 作为管理工作核心.计划和控制工作可以说是古己有之。然而，直到 20 世纪初，才产生了现代的科学管理思想。 1911 年，被称为“科学管理之父”的泰勒发表了《科学管理原则》一书，科学原则开始应用于管理领域。泰勒的科学管理思想主要集中在提高生产的效益上，如动作和时间研究、计时和计件工资、职能管理制度等。此外，泰勒还对科学管理的基本原理作了归纳。泰勒认为科学管理是一次思想革命，它不仅涉及到科学原则的应用、集体行动的协调、投入产出的分析等方面.还涉及到雇主和工人如何对待工作、同事如何对待和调整相互关系等问题。因此，它不仅是生产力的变革，更重要的是生产关系的变革。除泰勒以外，计划图表法的发明人甘特，现代经营管理理论的创始人法约尔等，都对科学管理的发展做出过重大贡献。 行为科学思想应用于管理工作。其主要代表人物是迈约。迈约曾进行了著名的霍桑试验。该试验的结果表明，实验小组无论在各种环境条件下，都有较高的生产效率。其主要原因在于小组成员因知道自己是试验对象而感到自豪。霍桑试验表明，士气、工作者之间关系、社会因素等是管理成功的重要因素。行为科学认为人是社会的人，企业应当为社会作贡献。企业应关心职工，并让工人参与企业管理 1.2论坛管理信息系统的发展意义 计算机开始应用于管理领域。 1954 年，美国商业界第一次使用计算机处理了工资单。此后计算机在会计、库存、计划等方面得到了广泛的应用，从而产生了以计算机技术为工具，通过对管理信息实施处理而最终服务于管理工作的信息系统。20 世纪 60 年代，掀起了管理信息系统建设的高潮。由以上发展过程可以看出，管理科学是一门综合性的学科，其本身不具有纯粹独立的技术和方法。管理工作的过程是对各学科领域先进的理论、思想、方法和技术的应用。任何先进的思想、方法和技术都会被管理工作所采纳吸收，从而对管理工作的发展产生推动作用。系统科学广泛应用于管理工作。20世纪 80 年代， BPR 理论对管理活动产生巨大的影响。管理活动就是在相关学科和理论的不断发展和促进过程中不断发展和完善的。

英语阅读理解带翻译：电视节目

英语阅读理解带翻译：电视节目 Television gives the American people a wide variety of programs from early morning until late at night. Operas, orchestral performances, chamber music and jazz concerts are often presented on television. So most of the leisure at home is used for watching television. Many Americans are so fond of their TV programs that they often have cold luncheon in front of their receiving sets. Television has given people newer and deeper understanding of history, art, music, literature, the ballet, the theater, the discoveries of modern science and the wonders of the universe. Television viewers pay no tax or charges for receiving programs on their sets. The cost of the programs is paid chiefly by those who are given the opportunity to advertise their goods or services during the commercial breaks. 美国人从清晨直到深夜都能看到形形色色的电视节目。电视屏幕 上经常播放歌剧、管弦乐、室内音乐和爵士音乐演奏。所以家庭中绝 大部分空闲时间都花在看电视上。很多美国人酷爱电视节目，经常在 电视机前边看电视边吃冷餐。电视使人们对历史、艺术、音乐、文学、舞剧、戏剧、现代科学的新发现和宇宙的奥妙有较新和较深切的了解。电视观众看电视节目既不用缴税，也不必付款，节目费用主要是由那 些借此为其商品和服务做插播广告的人支付的。

本科毕业设计(论文)外文翻译 译文： ASP ASP介绍 你是否对静态HTML网页感到厌倦呢？你是否想要创建动态网页呢？你是否想 要你的网页能够数据库存储呢？如果你回答：“是”，ASP可能会帮你解决。在2002年5月，微软预计世界上的ASP开发者将超过80万。你可能会有一个疑问什么是ASP。不用着急，等你读完这些，你讲会知道ASP是什么，ASP如何工作以及它能为我们做 什么。你准备好了吗？让我们一起去了解ASP。 什么是ASP? ASP为动态服务器网页。微软在1996年12月推出动态服务器网页,版本是3.0。微软公司的正式定义为:“动态服务器网页是一个开放的、编辑自由的应用环境,你可以将HTML、脚本、可重用的元件来创建动态的以及强大的网络基础业务方案。动态服务器网页服务器端脚本,IIS能够以支持Jscript和VBScript。”(2)。换句话说,ASP是微软技术开发的,能使您可以通过脚本如VBScript Jscript的帮助创建动态网站。微软的网站服务器都支持ASP技术并且是免费的。如果你有Window NT4.0服务器安装,你可以下载IIS（互联网信息服务器）3.0或4.0。如果你正在使用的Windows2000,IIS 5.0是它的一个免费的组件。如果你是Windows95/98,你可以下载(个人网络服务器(PWS),这是比IIS小的一个版本，可以从Windows95/98CD中安装，你也可以从微软的网站上免费下载这些产品。 好了，您已经学会了什么是ASP技术，接下来，您将学习ASP文件。它和HTML文 件相同吗？让我们开始研究它吧。 什么是ASP文件？ 一个ASP文件和一个HTML文件非常相似，它包含文本，HTML标签以及脚本，这些都在服务器中，广泛用在ASP网页上的脚本语言有2种，分别是VBScript和Jscript，VBScript与Visual Basic非常相似，而Jscript是微软JavaScript的版本。尽管如此，VBScript是ASP默认的脚本语言。另外，这两种脚本语言，只要你安装了ActiveX脚本引擎，你可以使用任意一个，例如PerlScript。 HTML文件和ASP文件的不同点是ASP文件有“.Asp”扩展名。此外，HTML标签和ASP代码的脚本分隔符也不同。一个脚本分隔符,标志着一个单位的开始和结束。HTML标签以小于号(<)开始(>)结束，而ASP以<%开始，%>结束，两者之间是服务端脚本。
