Decision Development in Computer-Assisted Group Decision Making

New computer technologies to aid group communication and decision making are becoming increasingly widespread. This study analyzes how one such technology, a group decision support system (GDSS), affected how group decisions developed over time. The study contrasted decision paths in groups using the GDSS with groups using the same procedural structures incorporated in the GDSS manually and with groups using no procedural structures. A flexible phase mapping method was employed to map group decision paths. The resulting set of seven decision paths varied in both sequence and number of decision phases. An optimal matching procedure was used to compute similarity measures among the 40 paths, and cluster analysis and multidimensional scaling were used to generate an empirical taxonomy of decision paths. Results indicated that the nature of decision paths varied both across the three conditions and within conditions. The decision path types were also related to three outcome variables: consensus change, perceived decision quality, and decision scheme satisfaction. Results indicated that those decision paths that most resembled logical normative sequences had superior outcomes to those that did not.     

Leadership among Patients in Group Therapy

Despite the nearly universally shared agreement among group therapists about the importance of group norms, empirical studies have rarely demonstrated a positive relationship between specific norms in psychotherapy groups and patient benefit. The study explored this relationship by examining the linkages between norms, a specific therapeutic process, and patient outcome. Examined were seventy-two spousal bereavement groups. Subjects' responses to a thirty-one item behavioral inventory were used to define norms; outcomes were based upon Time 1/Time 2 differences on a series of eleven measures indexing depression, anxiety, somatic symptoms, abuse of psychotropic medication, coping mastery, well-being, self-esteem, target problem rating, several measures of role stress and strain, and stigma. The findings suggest that normative characteristics were linked to a process, reciprocal social exchange, that influences positive outcomes. The results are preliminary, since they only serve to demonstrate such a relationship can exit.     

Attack on the Self: Charismatic Leadership and Authoritarian Group Supervision

Charismatic group leadership carries the potential for indoctrination and abuse when countertransference issues remain unexamined. This paper is a personal account of participation by the author in an authoritarian and confrontational supervisory experience with self-serving charismatic leadership. Group casualties are portrayed and discussed. This report applies self-psychological principles to understand the powerful merger of the compliant self and idealized object. Further, the dynamics of group identification with the aggressor are described through the Ferenczian lens of confusion of tongues.     

Personal and Professional Boundary Attitudes and Effective Group Leadership in Classrooms

The influence of personal boundary orientation (Boundary and Fusion dimensions of the Personal Boundary Questionnaire) and views on classroom boundary regulation (Classroom Boundary Questionnaire) on effective group leadership was studied by observation in classrooms of 8 male and 22 female elementary school teachers. A preference for higher personal boundaries was associated with a preference for greater regulation of classroom boundaries, which was in turn associated with less boundary-related activity in the classroom. Classrooms with less boundary-related activity had less active deviancy (all correlations p < .05). Tendencies toward fusion were not associated with differences in classroom management attitudes or behavior, but teachers with greater fusion tendencies had classrooms with less work involvement and a social climate characterized by more competition and friction (My Class Inventory scales). Personal and professional boundary attitudes helped to account for differences among teachers as effective group managers.     

Group Leadership: Practical Points for Beginners

Many practitioners do not use groups as a part of their counseling strategy because they lack applied skills or are discouraged by past failure. This article discusses eight practical points, often overlooked in establishing and running group programs. When properly applied, these points can have positive impact on the group leader's effectiveness.     

Microlevel Structuration in Computer-Supported Group Decision Making

The theory of Structuration focuses on how actions by members of social collectives create the structures that enable and constrain future action. Most previous research on Structuration in groups and organizations used qualitative case studies because Structuration is quite complex. This study introduces a method for the study of Structuration in larger samples of groups or organizations. A category system for the identification of structuring moves is described, along with several methods for characterizing short- and long-term trends in Structuration processes. The method is used to study how groups incorporate a computerized group decision support system (GDSS) into their decision processes. GDSSs are part of a class of new computer and communication technologies designed to help groups improve their meetings and make better decisions. Because GDSSs must be used by a group rather than an individual, social processes are critical in determining their effects on group outcomes. GDSSs influence groups by structuring their activities, and structurational processes are critical mediators of the impacts of GDSSs on group decision making. The study focused on the effects of restrictiveness of GDSS technology on Structuration processes and, in turn, on the relation of Structuration to a key group outcome, consensus change. The results suggest that two major types of structuring processes occur in computer-supported groups and that the nature of structuration is related to degree of consensus change.     

The Rank-Order Effect in Group Decision Making

Many studies indicate that group discussion candisproportionately reflect information known by all group members,at the expense of information known to only one group member, andthis is associated with suboptimal group decisions (Stasser &Titus, 1985). The present study examined the impact of threeprocedural factors on information sharing and quality of groupdecision: (a) group decision procedure (an instruction to "rankorder the alternatives" vs "choose the best alternative"), (b)information access during group discussion (reliance on memory vscomplete access), and (c) communication technology (computer vsface to face). Three-person groups worked on an investment decisionthat was structured as a hidden-profile task where criticalinformation was distributed unevenly prior to group discussion. Thedata provided support for a rank-order effect: Groups instructedto rank order the alternatives, compared to groups instructed tochoose the best alternative, were more likely to fully consider allof the alternatives, exchange information about unpopularalternatives, and make the best decision. But these effects onlyoccurred in face-to-face groups. In computer-mediated groups, therewas general information suppression and no effect of group decisionprocedure. Access to information during group discussion increaseddiscussion of both unique and common information, in theface-to-face conditions, but had no effect on group decisionquality. Taken together, the data suggest that procedural aspectsof group discussion may help overcome the impact of prediscussionpreferences on information processes and group decision.     

The Relationship Between Leadership Behaviors and Group Cohesion in Team Sports

The relationship between leadership behaviors and team cohesion among baseball and softball players at two school levels was analyzed in relation to predictions based on Chelladurai and Carron's (1978) Multidimensional Model of Leadership (MML). Athletes (n = 307) completed the perceived and preferred versions of the Leadership Scale for Sports (LSS) and the Group Environment Questionnaire (GEQ). Athletes' coaches (n = 23) completed the self-perceived version of the LSS. Task and social cohesion were assessed in relation to the scales of the three individual versions of the LSS and in relation to two types of discrepancy scores: value and perceptual. Although the concept of discrepancy is prominent in MML theory, the perceptual discrepancy score represents an innovation. Results indicated that, in general, team cohesion was most strongly related to the perceived LSS version and the perceptual discrepancy scores.

Decision difficulty and illusion of transparency in Japanese university students

People tend to believe that their inner thoughts are readily apparent to others. This study was conducted to examine effects, related to the difficulty of making decisions of personal preference, on the illusion of transparency, that is, the tendency people have to regard their own preference as more apparent to others when they have made their decision easily as opposed to situations in which they felt their decision to be difficult. In three studies in which the customary "transparency" experimental paradigm was used, university students were asked to rank choices of wedding dresses (Studies 1 and 3) or Korean movie stars (Study 2). Analysis suggested that the less difficulty participants felt in making their judgments (the first and last preference vs mid-ranking preference), the more they expected judgments to be transparent, especially when they had the clear intent to convey their thoughts to others. However, observers discerned first preferences no better than mid-ranking preferences. How inner subjective information contributes to the illusion of transparency is also discussed.     

Leadership and Regressive Small Group Processes: A Case Study

The psychoanalytic literature of regressive group and intergroup processes is reviewed briefly and selectively to derive principles of effective, working group leadership. These principles are applied to a case study of the leadership provided by Terje Larsen to the unique work group of Palestinians, Israelis, and Norwegians who produced the 1993 Oslo Peace Accords.     

Counsellor Interventions in Organisations

A counsellor occupies a potentially facilitative role in an organisation. Ways in which the counsellor can facilitate the development both of individuals and of the organisation of which they are members are discussed and are related to organisational transitional change and fantasy life. Possible interventions with individuals, groups and the organisation are outlined with the accent on development.     

New Directions in Sales Leadership Research

The changing environment facing sales organizations is characterized by the dimensions of complexity, collaboration, and accountability. Responding effectively to this dynamic environment requires a focus on specific leadership activities by senior sales leaders, field sales managers, and salespeople. A sales leadership framework is presented and used to identify and discuss specific leadership challenges and important research questions at different sales organization levels. Several new directions for sales leadership research are proposed to improve sales leadership thought and practice.     

Migrant Organisations in Humanitarian Action

This article applies the term ‘migrant humanitarianism’ for the hitherto neglected humanitarian activities of migrant organisations (MOs). First, it assesses the state-of-the-art on MOs in migration research and recognises common shortcomings within the existing literature. Second, it reviews humanitarian studies literature on aid actors and shows that local or non-Western forms of aid, as well as MOs have so far received only limited attention. Third, it presents the development studies on MOs’ role in their members’ country of origin, which focus mainly on remittances and the migration-development nexus. Fourth, it examines organisational studies which offer frameworks for analysing MOs in multiple countries and crises. Fifth, it discusses how neo-institutional and associational theory, as well as the transnational approach, can help fill gaps in research on MOs in humanitarian action. It then applies these theories to the Islamic Community Milli Görüs (IGMG) as a case study of MOs in humanitarian action. It shows that IGMG is a strong, autonomous actor, despite the fact that it does not fully adhere to the traditional humanitarian principles. Finally, it indicates themes for further research.
