The relative contribution of geographical dislocation, attachment styles, coping behaviours, and autonomy, to successful student adjustment, was examined in relation to stress and well-being. A sample of 142 on campus first year university students, across four Victorian university campuses completed self-report questionnaires. Questionnaires included demographic, social network, intrapsychic (attachment and autonomy), and coping variables. Multiple regression analysis revealed that being female, not having made a friend to confide in personal matters, lower achieved autonomy, and use of emotion-focused coping predicted higher levels of student stress. A second multiple regression analysis revealed that living away from home, and preferring others to approach oneself to initiate conversation or friendships predicted lower well-being, whilst increased frequency of phone and email contact, and greater secure parent and peer attachment, predicted greater well-being. Pearson's correlations indicated that securely attached students used more problem focused coping and social support, whereas insecurely attached students used more emotion focused coping. Qualitative data indicated student concerns about being away from family and friends, finance, course direction and structure, social opportunities on campus, and generally adjusting to the university culture. It was concluded that first year on-campus students would benefit from program initiatives targeting enhancement of on-campus social opportunities, development of autonomy, problem focused coping behaviour, interpersonal and social assertiveness.

For previous Fit e-Conferences, we have presented various aspects of our research on how person-environment (PE) fit and misfit compare. We have argued that because so little is known about how individuals experience fit and misfit at work, qualitative, exploratory research was called for (Talbot & Billsberry, 2007; 2008). Last year, our e-conference contribution detailed how using causal mapping in PE fit research would enable individuals’ experiences of fit and misfit to be captured and, as well as generating rich idiographic data, would further be amenable to nomothetic analysis (Talbot, Ambrosini & Billsberry, 2009). This paper briefly reviews why we set out to research employees’ fit and misfit perceptions, how we used causal mapping and discusses the main findings from our research.

An underlying assumption within person-organisation fit research has been that misfit and fit are opposite ends of a spectrum. However, little research has been conducted into the nature of misfit. This paper outlines a qualitative study to identify firstly, what causes employees to fit or misfit and secondly, whether these states are polar opposites or different constructs. The findings suggest that fit and misfit are categorical constructs as they are caused by different factors and impetuses. Although organisational factors caused both fit and misfit, supervisors appear instrumental in causing misfit perceptions and job factors seem closely aligned to fit perceptions.

What makes some people feel that they fit in at work whilst others feel they misfit? This brief paper outlines a study which is currently in progress to explore individuals’ perceptions of fit and misfit at work. In the person-organisation and person-environment fit literature, fit and misfit tend to be shown as two ends of a spectrum, with an underlying assumption being that the two states are polar opposites. Whilst this seems intuitively logical, there has been no empirical test of this core assumption in the literature. This paper outlines a qualitative study, using causal mapping, to identify the factors affecting employees’ fit and misfit perceptions at work. It is anticipated that by the time of the BAM conference, the data analysis will be complete and full findings will be available.

This paper addresses the well-established definitional issues in the organisational fit and misfit literatures. In particular, it reflects upon the poorly defined nature of the terms ‘fit’ and ‘misfit’ and the way they are used by researchers across languages and national borders. During a scholarly visit of the second author to the first author’s laboratory, it quickly became apparent that their understanding of the two terms was subtly different. These differences are discussed and implications developed. The paper ends with suggestions for how these differences might be systematically studied.

3D finite element simulations of 9-grain multicrystalline aggregates are performed within the framework of the classical continuum crystal plasticity and discrete dislocation dynamics. The results are processed in a statistical way by ensemble averaging. The comparison is made at three levels: macroscopic stress–strain curves, average stress values per grain, local values of stress and plastic strain. The comparison shows that some similarities are observed in the stress and strain distributions in both simulations approaches. But there are also large discrepancies caused by the discrete nature of plasticity in DDD. The DDD simulations provide higher stress levels in the aggregate due to the small number of dislocation sources and to the stress field induced by individual dislocations.

Chondrolabral lesions are uncommon after anteroinferior glenohumeral dislocations. This report describes a new dual-lesion complex that involved an avulsion of the anteroinferior glenoid labrum and a flap tear of the adjacent articular cartilage [glenoid labral tear and articular cartilage flap (GLAF) lesion]. The chondral component involved a large undermined region of the anterior half of the lower glenoid articular cartilage, and the labral component involved an avulsion from the 2.30–6 o’clock position on the glenoid. The labral tear was reconstructed with 3 suture anchors to form a neo-labrum in an attempt to overlap and stabilize the periphery of the chondral flap. A meniscal repair device was used to place a mattress stitch in the cartilage periphery to further stabilize the flap. This technique resulted in a secure repair without any chondral damage, and this remained intact on an MRI performed at a 3-month follow-up. A final 12-month follow-up showed complete recovery, as assessed by the Oxford shoulder instability score and Rowe score, and by a return to the pre-injury sporting level.
