    As the development and use of automated systems for collaborative work grows, the need for a better understanding of these systems becomes more important. The author's focus is on one type of system, a group support system (GSS), and in particular, on one important aspect of a GSS, anonymity. A conceptual framework for the study of anonymity in a GSS is presented, which describes the general class... View full abstract»

    Existing group decision support systems used in meeting rooms can help teams reach decisions quickly and efficiently. However, the decision models used by these systems are inadequate for many types of problems. The authors describe their laboratory's experience with knowledge acquisition systems and decision support tools. Their studies led them to develop a comprehensive decision model for group...

    Unlike physical or biological systems, human social systems are loosely-coupled in nature. Ambiguity and interpretation play important roles in human communication. Language is a key means of creating and maintaining shared realities through consensual processes. Consequently, an understanding of the interpretational nature of social interactions is required for the design of computer-mediated com... View full abstract»

    Seven financial parameters identified as possibly effective predictors of bond ratings produced by recognised agencies were used to train small multilayer neural networks. The rating predictions of trained networks were compared with the results from linear discriminant models. Networks made superior predictions in evaluating the bonds of the operating companies resulting from the divestiture of A... View full abstract»

    Hypertext technology is increasingly finding application in law firms, since much of the work of a lawyer involves accessing, assessing and sculpting text. There are some severe limitations inherent in hypertext. In document assembly, users break documents into small units (clauses and subclauses) and link them into a complex web, but links between text units do not cater for all associations of i...

    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»

    The paper presents some research on the application of artificial neural networks to economic modeling. The efficient markets hypothesis (EMH) states that at any time, the price of a security fully captures all known information about that stock, so the price behaves like a random walk in time, except when there are changes in information. The authors test whether a non-linear statistical method, ... View full abstract»

    A rapid change in the competitive environment may create an opportunity to use information technology to gain lasting competitive advantage. Often, however, a company will not possess all the resources needed to exploit these opportunities independently, or to do so with sufficient speed to achieve advantage. Under such conditions, companies may choose to cooperate with others to gain access to ne... View full abstract»

    The characteristics of information inhibit organizational learning cycles which are the processes necessary to develop intelligent organizations. One major thesis is that information is subject to limited appropriability since its exchange is irreversible, its performance is uncertain, and its use does not limit further use. Inappropriability encourages the retention of asymmetric information. Unf... View full abstract»

    Many empirical studies in MIS literature ask users for their evaluations of systems as a measure of IS success. These user evaluations are variously called user attitudes, information satisfaction, MIS appreciation, information channel disposition, value, usefulness, etc. Do all these terms refer to the same underlying construct? If there are different constructs, what are they, and which instrume... View full abstract»
