Book Description
"The Army's increasing interest in group cohesion has led to increased research effort in that area. This report describes an effort to integrate the cohesion performance research that employed real world groups using a meta- analytic approach. Tukey's (1977) stem and leaf display was used to display the data. The median effect size (product-moment correlation coefficient) for the data. The median effect size (product-moment correlation coefficient) for the 14 codable studies was .36, and the unweighted mean r was .42. When study effect sizes were weighted by the number of groups involved, the mean became .32. Rosenthal and Rubin's (1982) Binomial Effect Size Display (BESD) demonstrated that a correlation of .32 increases success rate (high performance) from 34 percent to 66 percent when cohesion is increased from low (below median) to high (above median). Although these findings are problematical because of the very small number of codable studies, as well as the conceptual and methodological problems associated with the cohesion performance research, higher levels of cohesion would seem to be very desirable for real world groups such as Army units." -- Abstract.

Book Description
This paper reports on a meta-analytic integration of the relation between group cohesiveness and performance. Overall, the cohesiveness-performance effect was highly significant and of small magnitude. Several theoretically informative determinants of the cohesiveness-performance effect were examined. This effect was significantly stronger when cohesiveness was operationalized in terms of measurements of group members' perceptions of cohesiveness than when cohesiveness was operationalized in terms of experimental inductions of cohesiveness. The results of this analysis suggest that the more direct effect may be from performance to cohesiveness rather than from cohesiveness to performance. Discussion considers the implications of these results for future research on the relation between cohesiveness and performance.

Book Description
"Threshold Concepts in Practice brings together fifty researchers from sixteen countries and a wide variety of disciplines to analyse their teaching practice, and the learning experiences of their students, through the lens of the Threshold Concepts Framework. In any discipline, there are certain concepts – the ‘jewels in the curriculum’ – whose acquisition is akin to passing through a portal. Learners enter new conceptual (and often affective) territory. Previously inaccessible ways of thinking or practising come into view, without which they cannot progress, and which offer a transformed internal view of subject landscape, or even world view. These conceptual gateways are integrative, exposing the previously hidden interrelatedness of ideas, and are irreversible. However they frequently present troublesome knowledge and are often points at which students become stuck. Difficulty in understanding may leave the learner in a ‘liminal’ state of transition, a ‘betwixt and between’ space of knowing and not knowing, where understanding can approximate to a form of mimicry. Learners navigating such spaces report a sense of uncertainty, ambiguity, paradox, anxiety, even chaos. The liminal space may equally be one of awe and wonderment. Thresholds research identifies these spaces as key transformational points, crucial to the learner’s development but where they can oscillate and remain for considerable periods. These spaces require not only conceptual but ontological and discursive shifts. This volume, the fourth in a tetralogy on Threshold Concepts, discusses student experiences, and the curriculum interventions of their teachers, in a range of disciplines and professional practices including medicine, law, engineering, architecture and military education.

Book Description
This report describes the relationships between measures of cohesion obtained on nine U.S. Army light infantry platoons at home station and the subsequent performance of those platoons at the Joint Readiness Training Center (JRTC). The JRTC performance was measured by observer/controllers using tank evaluation and observation checklists and also by company commanders using summary ratings. When outlier cases were controlled, bonding among leaders, soldiers, and between leaders and their soldiers was strong and correlated significantly with platoon performance as measured by the observer/controllers. Correlations with company commander ratings were positive but not significant. The strongest correlations were between the types of bonding listed above and the preparation subtask of task performance. However, because of the limited number of platoons involved, replication is needed to confirm the results, and caution must be used in drawing conclusions.

Book Description
From the Introduction: The study reported here is concerned with group cohesion. However, since it takes place in an industrial setting, it may be more accurate to say that the study is concerned with work group cohesion. It deals primarily with a statement of the behavior and feelings of group members that differentiate high cohesive groups from low cohesive groups. Secondary cocerns are an investigation of conditions that facilitate group cohesion, and an examination of the relationship between degrees of cohesion and certain consequences, such as productivity levels, tension, and absenteeism rates of group members.
