Do individual perceptions of group cohesion reflect shared beliefs? An empirical analysis

This study's primary purpose was to examine the degree to which individual perceptions of cohesiveness reflect shared beliefs in sport teams. The secondary purposes were to examine how the type of cohesion, the task interactive nature of the group, and the absolute level of cohesion relate to the index of agreement. Teams (n = 192 containing 2,107 athletes) were tested on the Group Environment Questionnaire. Index of agreement values were greater for the group integration (GI) manifestations of cohesiveness (GI-task, rwg(j) = .721; GI-social,rwg(j) = .694) than for the individual attractions to the group (ATG) manifestations (ATG-task, rwg(j) = .621; ATG-social, rwg(j) = .563). No differences were found for interactive versus coactive/independent sport teams. A positive relationship was observed between the absolute level of cohesiveness and the index of agreement. Results were discussed in terms of their implication for the aggregation of individual perceptions of cohesion to represent the group construct.

Improvement of the prediction accuracy and efficiency of hot strength of austenitic steels with optimised ANN training schemes

The hot strength of austenitic steels of different carbon contents was modelled using an artificial neural network (ANN) model with optimum training data. As training data employed in a traditional neural network model were randomly selected from experimental data, they were not representative and the prediction accuracy and efficiency were therefore significantly affected. In this work, only representatively experimental data were used for training and during the procedure, one tenth of the training data extracted from experiment were used for testing the training model and terminating the modelling. The effects of the carbon con tent on flow stress, peak strains and peak stresses observed from the experiment for both training and test data were accurately represented with the ANN scheme reported in this work.

‘There isn’t kind of a White History Month or anything like that for them’: equity, schooling and the problematics of group identity politics

This paper explores issues of equity and group identity at ‘Hamilton Court’, a large comprehensive multi-faith and multi-cultural school located in England. The exploration draws on data gathered from a study that examined the conditions, structures and practices associated with productively addressing issues of justice and cultural diversity. The paper focuses, in particular, on the voices of two learning mentors, ‘Rosanna’ and ‘Yasmeen’. With reference to a cultural event at the school based around an Asian-inspired Bollywood Dance Festival, the school’s approach to absence requests on the basis of religious observance, and the disadvantage experienced by a particular White British working class boy, the paper highlights tensions and problematics associated with issues of equity, schooling and group identity. The paper makes a theoretical contribution to debates in this area. Further illustrating the limitations of distributive understandings of equity that begin with group identity politics and fail to consider matters of context in struggles against cultural oppressions, it examines the possibilities of an equity approach that instead begins with a focus on overcoming these relations of oppression.

Political justice, schooling and issues of group identity

This article explores issues associated with schooling and political justice. Such issues are understood in light of the contention surrounding howWestern schooling contexts might best represent marginalised groups—in ways that accord them a political voice. The significance of group identity politics is explored drawing on international debates associated with ethnically segregated schooling. A postcolonial theorising of group identity highlights the ways in which segregated schooling can both support and undermine politically just representation for marginalised students. This theorising draws attention to the problematic notion of voice in linking representation to identity in reductionist ways. The arguments presented point to the significance of people and their politics, rather than their membership to a particular identity group, in pursuing equity for marginalised groups. The article argues the imperative of understanding group identity as an aspect of negotiated social practice that can be drawn on in strategic and critical ways to address matters of political injustice.

An evaluation of group work in first-year engineering design education

It is argued that ‘design' is an essential characteristic of engineering practice, and hence, an essential theme of engineering education. It is suggested that first-year design courses enhance commencing student motivation and retention, and introduce engineering application content and basic design experience early in the curriculum. The research literature indicates that engineering design practice is a deeply social process, with collaboration and group interactions required at almost every stage. This chapter documents the evaluation of the initial and subsequent second offerings of a first-year engineering design unit at Griffith University in Australia. The unit 1006ENG Design and Professional Skills aims to provide an introduction to engineering design and professional practice through a project-based approach to problem solving. The unit learning design incorporates student group work, and uses self-and-peer-assessment to incorporate aspects of the design process into the unit assessment and to provide a mechanism for individualization of student marks.

Negotiating meaning: Effects of group dynamics on information system development.

The research explored the impacts that the psychological processes within and between work groups had on software development and IS project failure. It has identified and demonstrated ways to moderate such group dynamics and their causes; in turn providing an approach to reduce IS project failure.
