    The paper evaluates neural networks as a univariate forecasting tool for two agricultural price series: weekly closing prices for live cattle and daily settlement prices for corn. Performance was evaluated using root mean squared error and mean absolute percentage error. Neural networks outperformed the best traditional method for cattle price forecasts made four, eight, and twelve weeks into the ... View full abstract»

    The paper describes a neural network system for forecasting time series and its application to a non-trivial task in forecasting currency exchange rates. The architecture consists of a two-layer backpropagation network with a fixed number of inputs modelling a window moving along the time series in fixed steps to capture the regularities in the underlying data. Several network configurations are d... View full abstract»

    A negotiation support system (NSS) is commonly defined as a set of negotiator's individual decision support systems (DSS) interconnected with a communications/group decision component. The author presents a three-step design framework to build a negotiator's DSS that offers its user analytical and strategic insights about the counterpart(s). The purpose of such an NSS is to improve the user's barg... View full abstract»

    Group support systems (GSS) and their effects on group processes and outcomes have been an object of intense study over the past ten years (1982-92). The purpose of the authors is to take a different perspective with respect to GSS research. Rather than discussing research about GSS, they discuss the capabilities of GSS tools to support the process of doing research. A model of the steps involved ... View full abstract»

    As members of a group begin to interact and solve problems, a group schema evolves. This group cognitive structure is the result of realized consensus about and coverage of the problem domain of the group; and it becomes the mechanism by which the group structures and solves problems. The authors describe how a technological agent can be used to control and enhance the evolution of the group schem... View full abstract»

    Adaptive structuration theory (AST) provides a sound basis from which to study the use of group support systems (GSS). The need for a theoretical approach such as AST is especially urgent because it helps explain the process of GSS use, thereby providing insights into the reasons for inconsistent research results. The paper illustrates the development of a research model based on AST, and reports ... View full abstract»

    Roughly half of all organization communication is dyadic, and new media will offer new possibilities for dyadic communication. Yet relatively little research has been done on differences between business pairs and larger groups or on the technology support needs of organizational dyads. The paper discusses the importance of dyadic organization communication and the kinds of research that will be n... View full abstract»

    An overview is given of the existing negotiation literature under the headings of game theory, economic models, political models, and sociological models. Inferring from the review the need for computer support for negotiation, the authors then propose a theory for understanding the effects due to a support system in a two-party, monolithic, and multiple-issue setting. The theory conceptualizes a ... View full abstract»

    `Use-of-time' studies, which have been popularized by H. Mintzberg (1973), have already told us a great deal about managerial and professional groupwork. The author discusses needs to extend use of time methodologies to tell us more. Time methodologies work like this: either an observer watches a manager working or the manager keeps a detailed diary and, for each activity event, a form is filled o... View full abstract»

    The psychology, speech communications, and management literature is rich with theory on the topic of group history and development. Three general categories of developmental models have been proposed: progressive, cyclical, and non-sequential. These models suggest that group performance, member behavior, and task focus change as the group matures and develops. Group support systems (GSS) have been... View full abstract»

    Interacting groups fail to make judgments as accurate as those of their most capable members due to problems associated with both interaction processes and cognitive processing. Group process techniques and decision analytic tools have been used with groups to combat these problems. While such techniques and tools do improve the quality of group judgment, they have not enabled groups to make judgm... View full abstract»
