The literature provides multiple measures of diversity along a single demographic dimension, but when it comes to studying the interaction of multiple diversity types (e.g. age, gender, and race), the field of useable measures diminishes. We present the use of decision trees as a machine learning technique to automatically identify the…

Improving conditions of learning is a priority for schools, communities, states, and the federal government. Students are the stakeholders with the most to gain or lose and should be consulted about their classroom experiences as a basis for continuous school improvement planning. The population of 461 students from a rural public high school in…

Focusing on five models of committee effectiveness for purposes of this assessment will lend insight into the strengths and weaknesses of utilizing a structured action plan as a guide to achieving and maintaining optimum committee effectiveness in higher education. In the compilation of the strengths and weaknesses of committee decision making,…

Many joint decisions in everyday life (e.g., Which bar is less crowded?) depend on approximate enumeration, but very little is known about the psychological characteristics of counting together. Here we systematically investigated collective approximate enumeration. Pairs of participants made individual and collective enumeration judgments in a…

Multi-agency crisis management represents one of the most complex of real-world situations, requiring rapid negotiation and decision-making under extreme pressure. However, the training offered to strategic planners, called Gold Commanders, does not place them under any such pressure. It takes the form of paper-based, table-top exercises, or…

We introduce a game theory model of individual decisions to cooperate by contributing personal resources to group decisions versus by free riding on the contributions of other members. In contrast to most public-goods games that assume group returns are linear in individual contributions, the present model assumes decreasing marginal group…

This article presents the authors' response to Hewes's (1986, 1996, 2009) models of communication effects on small group outcomes. As sophisticated and thoughtful as Hewes's new model is, however, the authors take issue with it. For one, there is reason to question whether his approach is feasible. For another, his models are not founded on solid…

This article presents the author's response to Professor Hewes's "The Influence of Communication Processes on Group Outcomes: Antithesis and Thesis." The author believes that Hewes could have been more helpful to the reader and to those who are apt to find inspiration in the steps he has taken in his essay to promote a "return to basic theorizing…

This paper develops a conceptual model of the crisis-decision process, focusing on links susceptible to emergence of pathologies, and proposes preventive measures to increase the coping abilities of decision units. (Author)

Describes the Persuasive Arguments Theory (PAT), a noninteractional theory of group decision-making that predicts postdiscussion shifts from prediscussion cognitive arguments, elaborates on it, and advances two models to test the PAT perspective on argument. Finds the second model demonstrates superior predictive ability to the PAT model at some…

Groups are a fundamental part of the business world. Yet, as companies continue to expand internationally, a major challenge lies in promoting effective communication among employees who work in varying time zones. Global expansion often requires group collaboration through computer systems. Computer-mediated groups lead to different communicative…

Discusses Johnson's theory that information can be gathered in either a systematic or spontaneous manner and that this information will be analyzed either internally or externally, and considers some of its implications for understanding group interactions. Models of decision-making styles and characteristics and the problem-solving process are…

Presents a theoretically integrated, eclectic view of a decision-making, learning model of group counseling. Describes stages that the process moves through, gives the characteristics of each stage, and techniques that are helpful to facilitate this group counseling process. (Author)

Whenever group work takes place, rules and norms are established by group members. Rules are typically written and formally stated by group members, whereas norms are more informal and are implicitly stated. But regardless of how rules and norms are established, they enable group members to develop procedures from which the group can function.…

Backtrack problem-solving appears to be a viable alternative to current problem-solving methodologies. It appears to have considerable heuristic potential as a conceptual and operational framework for small group communication research, as well as functional utility for the student group in the small group class or the management team in the…
