Computer support for work groups and cooperative work tasks is an area of active research and development. Software products are advertised for facilitating cooperation and collaboration, from collective authoring systems to computer support for multimedia communications and face-to-face meetings. Increasing work group productivity through the use of computer technology requires that the nature of group work practice be well understood. This paper describes a psychodynamic model of group relations and the perspective it provides on the behaviors and motivations of work groups and their larger containing organizations. The paper argues that the systemic and psychological model and insights of the psychodynamic perspective are fundamental to an understanding of the actual day-to-day activities of work groups. Furthermore, utilizing these insights can help develop richer models of work group experience, and provide a more realistic ground for developing effective computer assistance for work groups and their tasks. Since computer systems affect the social conditions of work groups, models and methods of the social sciences must be incorporated into the development practices of computer system engineers. The value of the psychodynamic perspective is described with two examples. First, some current research on computer mediated communication is reviewed in terms of group relations. Second, the application of this model to the changing nature of organizational work is outlined. * Email: Anderson roch817@Xerox. com
对工作组和合作工作任务的计算机支持是一个积极研究和发展的领域。软件产品被宣传为促进合作和协作,从集体创作系统到多媒体通信和面对面会议的计算机支持。通过使用计算机技术来提高工作组的工作效率需要充分理解小组工作实践的性质。本文描述了一个群体关系的心理动力学模型,以及它为工作群体及其更大的包含组织的行为和动机提供的视角。本文认为,系统和心理模型以及心理动力学视角的见解是理解工作群体实际日常活动的基础。此外,利用这些见解可以帮助开发更丰富的工作组经验模型,并为为工作组及其任务开发有效的计算机辅助提供更现实的基础。由于计算机系统影响工作群体的社会条件,社会科学的模型和方法必须纳入计算机系统工程师的开发实践。用两个例子来说明心理动力学视角的价值。本文首先从群体关系的角度对计算机媒介传播的研究现状进行了综述。其次,概述了该模型在组织工作性质变化中的应用。*邮箱:Anderson roch817@Xerox。com

An approach to formalizing organizational open systems concepts 形式化组织开放系统概念的方法
Pub Date : 1991-10-01 DOI: 10.1145/122831.122845
Y. Wand, C. Woo
The view of organizations as open systems has recently received substantial attention. Under this view, an organization is a group of cooperative and competitive units working together to achieve certain individual and social goals. In this abrticle, we propose an approach to formaJize open systems concepts based on ontolo~, the branch of philosophy dealing with models of the world. Specifically, we propose a dual view of organizations – as wholes and as aggregates of components. This duality provides for viewing organizational units as both independently behaving components of the organization, and, in the same time, as subject to organizational constraints or laws. The laws force the components to cooperate, exchange information and coordinate their activities with other units. We conjecture that our proposed approach can provide precise formal definitions for open system concepts.
将组织视为开放系统的观点最近受到了广泛关注。在这种观点下,组织是一群合作和竞争的单位,为了实现一定的个人和社会目标而共同努力。在本文中,我们提出了一种基于控制论的方法来形式化开放系统概念,控制论是处理世界模型的哲学分支。具体地说,我们提出了组织的双重观点-作为整体和作为组件的集合。这种二元性提供了将组织单位视为组织中独立行为的组成部分,同时也受组织约束或法律的约束。这些规律迫使各组成部分与其他单位进行合作、交换信息和协调活动。我们推测我们提出的方法可以为开放系统概念提供精确的形式化定义。

The representation of policies as system objects 将策略表示为系统对象
Pub Date : 1991-10-01 DOI: 10.1145/122831.122850
J. Moffett, M. Sloman
This is an exploratory paper in which we describe aspects of management policy which could be modelled as objects in a distributed computer system, in order to enable them to be queried and manipulated. Policies are 'the plans of an organisation to meet its goals'. They are persistent entities which are intended to influence actions, either by motivating actions or by authorising them. This distinction reflects the observation that agents only successfully carry out actions if they are both motivated and empowered to do so. In addition to persistence, policies have other main characteristics: they are directed to subjects; they are typically organised in hierarchies in which the goal of a policy is achieved by creating lower-level policies until identifiable actions are completed; and policies may conflict, so they require to have a precedence ordering. There is a need to represent and manipulate policies, as objects within the computer system, so that they can be used to influence the activities of automated managers within large distributed computer systems. We describe a possible structure for policy objects and the operations which can be performed on them. Their attributes include: modality (positive or negative motivation or authorisation); policy subjects, goals, and target objects; and the constraints which may apply. The method of representation of relationships between policies is left as an open issue. Related work and concepts in the modelling of policies are referred to, including a brief discussion of security models in this context. The open issues raised by this paper are described.
这是一篇探索性的论文,我们描述了管理策略的各个方面,这些方面可以建模为分布式计算机系统中的对象,以便能够对它们进行查询和操作。政策是“一个组织为实现其目标而制定的计划”。它们是持续存在的实体,旨在通过激励行动或授权行动来影响行动。这种区别反映了这样一种观察,即行动者只有在既有动机又有授权的情况下才能成功地执行行动。除了持久性之外,政策还有其他主要特点:它们是针对主体的;它们通常以层次结构组织,其中通过创建较低级别的策略来实现策略的目标,直到完成可识别的操作;并且策略可能会冲突,因此它们需要有优先顺序。需要将策略作为计算机系统中的对象来表示和操作,以便它们可以用来影响大型分布式计算机系统中的自动化管理器的活动。我们描述了策略对象的可能结构以及可以对其执行的操作。其属性包括:方式(积极或消极的动机或授权);政策主体、目标和目标对象;以及可能适用的约束条件。表示策略之间关系的方法仍然是一个悬而未决的问题。本文引用了策略建模中的相关工作和概念,包括在此上下文中对安全模型的简要讨论。阐述了本文提出的开放性问题。

A goal oriented office form system 目标导向的办公表单系统
Pub Date : 1991-10-01 DOI: 10.1145/122831.122842
Heyun Liu, Ian Dranffan, F. Poole
This paper presents a goal oriented office form system. Comparing to the previous developed office form $ystems, two contributions have been made by this system. First, basedon the AI frame system and the unification process, an office form pattern language k developed. This pattern language can handle the association of a form to hasubforms which have a group of repetitions of the same structure. Second, an AI planner which can directly manipulate the office forms is achieved. The specific difficulty for developing a ptanner to directly manipulate office forms is the frame problem [Hayes, 1975]. Since office form entity can no longer be represented by a symbol ora relation, the situation representation in the planning network has to consider not only the changes of some office forms against the whole office form base, but also the changes of the attributes against the form in which the attributes are located. The goal oriented office form system is developed based on constraint manipulation.
本文提出了一个目标导向的办公表单系统。与以往开发的office form $系统相比,本系统做出了两个贡献。首先,基于AI框架体系和统一过程,开发了办公表单模式语言k。这种模式语言可以处理表单与具有相同结构的一组重复的子表单之间的关联。其次,实现了一个可以直接操作办公表单的人工智能规划器。开发一个直接操作办公表格的程序的具体困难是框架问题[Hayes, 1975]。由于办公形式实体不能再用符号或关系来表示,规划网络中的态势表示不仅要考虑某些办公形式相对于整个办公形式基础的变化,还要考虑属性相对于属性所在的形式的变化。基于约束操作,开发了面向目标的办公表单系统。

Organizational modelling and problem solving using object-oriented knowledge representation server and visual language 使用面向对象的知识表示服务器和可视化语言进行组织建模和问题解决
Pub Date : 1991-10-01 DOI: 10.1145/122831.122839

Object-oriented knowledge representation systems allow an organization to be modeled in an understandable way. User interaction with such a system is enhanced if the graphic representations normally used, such as organization charts and room layout plans, are supported through visual languages directly generating the underlying knowledge structures. The operational and problem-solving procedures of an organization expressed visually within this framework become overt and accessible, and their implementation and consequences can be automated and evaluated. This paper reports some experience in the design and implementation of a lightweight, objectoriented knowledge representation server, and its application to organizational modeling and problem solving. The primary user interface is through a formal visual language implemented as a drawing environment on graphic workstations. The open architecture implementation of the server allows it to be integrated with existing applications, such as corporate database and accounting systems, and also allows functionality to be added through self-contained modules requiring no changes in the kernel system.
面向对象的知识表示系统允许以一种可理解的方式对组织进行建模。如果通过直接生成底层知识结构的可视化语言支持通常使用的图形表示,例如组织图和房间布局计划,则可以增强用户与此类系统的交互。在这个框架内可视化地表达的组织的操作和解决问题的过程变得公开和可访问,并且它们的实现和结果可以被自动化和评估。本文介绍了一个轻量级的、面向对象的知识表示服务器的设计和实现,以及它在组织建模和问题解决中的应用。主要的用户界面是通过一种正式的视觉语言实现的,作为图形工作站上的绘图环境。服务器的开放体系结构实现允许它与现有的应用程序集成,例如公司数据库和会计系统,并且还允许通过自包含模块添加功能,而无需在内核系统中进行更改。

Ronald H. Nowaczyk, Terri L. Thomas, D. O. White
past research on interactions of inditiiduals located in separate locations has provided little evidence of a beneficial effect for video co-presence. The current study required users to work in pairs on a cooperative task. College students used a variety of information to select an apartment to rent. The desktop conferencing arrangement included the presence or not of video of the partners. The results revealed a significant difference as a function of gender . Video co-presence influenced the access of information for women, but not for men. Women also felt that the final choice agreed upon was their individual first choice, while men did not. The findings are discussed in terms of the potential role of video in desktop conferencing.
过去对位于不同地点的个体互动的研究几乎没有提供视频共同存在有益效果的证据。目前的研究要求用户两人一组完成一项合作任务。大学生利用各种各样的信息来选择出租的公寓。桌面会议安排包括合作伙伴是否有视频。结果显示了显著的性别差异。视频共同出席对女性获取信息有影响,但对男性没有影响。女性还认为最终达成一致的选择是她们个人的第一选择,而男性则不然。研究结果讨论了视频在桌面会议中的潜在作用。

Locator technology in distributed systems: the Active Badge 分布式系统中的定位技术:活动徽章
Pub Date : 1991-10-01 DOI: 10.1145/122831.122858

Experiments with technology for locating and tracking people and things are occurring in computer science research centers in Europe and the United States. Although in its early stages, this location capability is viewed as an enabler for nextgeneration distributed computing systems in offices, universities, and perhaps the wider world. Such systems will no longer shackle users to their desktop PC or leave them stranded, unconnected, when using portable and notebook systems. Instead, ubiquitous wireless networks will track users and machines, delivering information and services as needed to people on the go [SciAm91 ].

The major challenge in the design of an efficient distributed multimedia system is the integration and support of a wide variety of applications. Investigating the basic issues involved in the design and specification of distributed muttimcdia systems is the focus of this paper. A basic layered network architecture is proposed as the uniform framework for the investigation of different levels of functionality typically associated with the communication network that supports multimedia communication. Within this framework, we propose to identify the communication requirements for multimedia applications and characterize a set of communication primitives which specify different qualities of scrvicc to reflect different real-time rcquircmcnts. ‘Ilis investigation is guided by an efficient and flexible multi-level specification model. We will characterize this model and show that the model can be amenable to the construction of a set of communication primitives that support synchronization and communication of multimedia applications.
设计一个高效的分布式多媒体系统的主要挑战是对各种应用程序的集成和支持。研究分布式多媒体系统设计和规范中涉及的基本问题是本文的重点。提出了一个基本的分层网络体系结构作为统一的框架,用于研究通常与支持多媒体通信的通信网络相关的不同级别的功能。在这个框架内,我们建议确定多媒体应用程序的通信需求,并描述一组通信原语,这些原语指定了不同的服务质量,以反映不同的实时要求。他的调查是由一个高效、灵活的多层次规范模型指导的。我们将描述该模型的特征,并说明该模型可用于构建一组支持多媒体应用程序同步和通信的通信原语。

Recently, there has been considerable interest in the development of computer systems for use in negotiations. However, these systems are exclusively focussed on joint problem solving in cooperative settings. This paper concentrates on negotiation situations that are marked by conflict. Using a social-theoretic framework we identify the scope of computer assistance for negotiation in non-cooperative situations. We focus on the descriptive part of Raiffa’s asymmetric descriptive/prescriptive strategy for competitive decision-making. An outline of a software system is presented. Such a system can help build a database of negotiation case histories that can be represented graphically. We explore its use in competitive bargaining situations where the system can provide a descriptive model of the opponents’ bargaining behavior and help classify a negotiator in terms of negotiation strategies he is inclined to use. This allows the user to adopt a prescriptive approach in t~. process of concession-making in negotiations. The principles of a computer program FACILITATOR to facilitate the process of negotiation are also presented. * chaudhur@umb sky.bitnet ** mgmtrao@acsu.buffalo.edu *** sukuntar@emx.utex as.edu Permission to copy without fee all or part of this material is granted provided that the copies are not made or distributed for direct commercial advantage, the ACM copyright notice and the title of the publication and its date appear, and notice is given that copying is by permission of the Association for Computing Machinery.

最近,人们对开发用于谈判的计算机系统很感兴趣。然而,这些系统专门侧重于在合作环境中共同解决问题。本文主要研究以冲突为特征的谈判情境。利用社会理论框架,我们确定了在非合作情况下计算机协助谈判的范围。我们关注的是Raiffa的非对称描述性/规范性竞争决策策略的描述性部分。给出了一个软件系统的概要。这样的系统可以帮助建立一个可以图形化表示的谈判案例历史数据库。我们探索了它在竞争性议价情境中的应用,该系统可以提供对手议价行为的描述性模型,并帮助根据谈判者倾向于使用的谈判策略对其进行分类。这允许用户在t~中采用规定性的方法。谈判中作出让步的过程。本文还介绍了一个计算机程序FACILITATOR的原理,以促进谈判过程。* chaudhur@umb sky。bitnet ** mgmtrao@acsu.buffalo.edu ** sukuntar@emx.utex as.edu允许免费复制本材料的全部或部分内容,前提是这些副本不是为了直接的商业利益而制作或分发的,必须出现ACM版权声明、出版物的标题和日期,并注明复制是由计算机协会许可的。以其他方式复制或重新发布需要付费和/或特定许可。a 1991 ACM 0-89791-456 /91 /0010 /0269…1.50美元
