A Study of Collaborative Group Work With and Without Computer-Based Support

Information Systems Research 1990
As organizational environments become more turbulent and as managers spend more time in meetings in an effort to deal with that turbulence, using information technology to support meetings has become more important. This paper reports on an experiment that compared meetings supported by information technology to meetings with conventional manual support only. The experiment differs from most previous group decision support system (GDSS) experiments in that solutions to the task it used could be objectively scored, it introduced assigned leadership as an independent variable, and it is the first GDSS experiment to compare use of a subset of the University of Arizona GroupSystems GDSS tools to manual group methods. In addition to a communication condition (GDSS or manual) and assigned leadership, the experiment also investigated the effects of anonymity on group process and outcomes. The experiment found that GDSS groups were less likely to reach consensus, took more time to reach a decision, and had more equal levels of member participation than manual groups. No main effects were found for assigned leadership or anonymity.

Electronic Integration and Strategic Advantage: A Quasi-Experimental Study in the Insurance Industry

Information Systems Research 1990
Strategic advantage through information technology is a popular and an important theme, but the extent of research support is minimal, anecdotal, and sporadic. This paper reports the results of a quasi-experimental study on the impact of dedicated electronic integration [between a focal insurance carrier and its independent agents in the property and casualty (P&C) market] for the focal carrier. The results indicate that the agents that are electronically interfaced with the carrier report improvements in a set of four performance factors in the expected direction (six months after system installation), but statistically different from a matched set of non-interfaced agents (based on size, state, and location category) only in terms of increases in new business policies, but not in terms of effectiveness—namely, neither increases in premiums and commissions nor operating efficiency. Some explanations, extensions and research implications are outlined.

The Adoption of Spreadsheet Software: Testing Innovation Diffusion Theory in the Context of End-User Computing

Information Systems Research 1990
Judging by the wealth of problems reported in the literature, information systems (IS) and general managers are not sure how to manage the introduction of new information technology. One step toward providing sound management guidelines is to improve understanding of the social forces which affect the introduction and diffusion process within organizations. This research takes a step toward that goal by examining the validity of innovation diffusion theory within the context of end-user computing. The research involved a field study and historical analysis of the diffusion of spreadsheet software in organizations. To assist in controlling exogenous factors, only finance and accounting departments were studied. Over 500 professionals in 24 business units from 18 large businesses in manufacturing and services participated in the research. Findings supported hypotheses that earlier adopters of spreadsheet software were younger, more highly educated, more attuned to mass media, more involved in interpersonal communication, and more likely to be opinion leaders. Also supported was the hypothesized sigmoidal distribution of adoption over time. Application of the theory was not supported in all areas, however, suggesting that information technology diffusion is different from other diffusion phenomena. Contrary to theory, interpersonal channels of communication were dominant in all phases of adoption decision making. And contrary to their hypothesized role as change agent, IS departments played a minor role in the diffusion process. This was consistent with the observed user-led nature of the phenomenon. Implications for research and practice are discussed.

Effective IS Security: An Empirical Study

Information Systems Research 1990 1(3), 255-276
Information security has not been a high priority for most managers. Many permit their installations to be either lightly protected or wholly unprotected, apparently willing to risk major losses from computer abuse. This study, based on the criminological theory of general deterrence, investigates whether a management decision to invest in IS security results in more effective control of computer abuse. Data gathered through a survey of 1,211 randomly selected organizations indicates that security countermeasures that include deterrent administrative procedures and preventive security software will result in significantly lower computer abuse. Knowledge about these relationships is useful for making key decisions about the security function.

Grain boundaries in silicon from zero temperature through melting

Information Systems Research 1988
The results of atomistic simulations of twist grain boundaries in covalent silicon are presented and compared with similar studies in metals. Three aspects are discussed in detail: (i) the zero-temperature structure-energy correlation, (ii) the elastic anomalies near a twist boundary at zero temperature, and (iii) the high-temperature stability of a boundary and its role in thermodynamic melting. In each case striking similarities with studies on metals are found, which are attributed to the important role played by atoms in close proximity. By contrast the covalent nature of bonding in silicon appears to play only a minor role.
