Can you pull it off? Appearance modifying behaviours adopted by wig users with alopecia in social interactions.

In the academic and medical literature on alopecia, wigs (hair prostheses) are typically recommended as a coping strategy: a device to camouflage, conceal, or cover hair loss, and cope with the psychological impact of a dramatic change in body image. This paper used Goffman's (1959) theory of impression management to demonstrate (a) the social significance of self-presentation, and (b) how adults with alopecia managed their wig use in their daily lives. Data from 14 interviews, two focus groups and six video diaries with 22 Caucasian adults (19 females, 3 males; 29-74 years, SD=13.

Research synthesis of recommended acetabular cup orientations for total hip arthroplasty.

Total hip arthroplasty (THA) is regarded as one of the most successful surgical procedures of modern times yet continues to be associated with a small but significant complication rate. Many early failures may be associated with poor component positioning with, in particular, acetabular component orientation dependent on the subjective judgement of the surgeon. In this paper, we compare the manufacturers' instructions on acetabular cup orientation with the literature-based recommended safety zones and surgical technique, by transforming them onto a single, clinically-relevant framework in which the different reference systems, safety guidelines and current instrumentation surgical techniques can be evaluated.

A novel device for evaluating forces during the dynamic jar opening action--do older and younger adults do things differently?

Package opening tasks have been identified as some of the most challenging that individuals need to perform to access food. There is little previous study of the 3D hand loading that is required to open these products. A novel load measuring device was used to characterise torque, squeeze and compression forces during the dynamic action of jar opening for young and older adults.
