This study compared 80 gay and straight Australian males on self report measures of body satisfaction, masculinity, femininity, narcissism, and reasons for exercising at gyms to explore factors related to excessive exercise. Gay males are less satisfied with their bodies compared to straight males. Improving appearance was more important for gay men, while fun was considered more important for straight men. Only sexual orientation and masculinity contributed independently to body satisfaction. Straight males who scored high on masculinity were most satisfied with their bodies, while gay males who scored low on masculinity were least satisfied with their bodies, irrespective of femininity and narcissism. Hours exercising per week and fun as a reason for exercising, significantly contributed to body satisfaction.

This paper describes an approach to teaching systems thinking and associated capacity building for a team of professionals and managers from a developing country (Vietnam), engaged in the sustainable management of a world biosphere reserve. Vietnamese environmental and development managers and UNESCO were attracted to a systems approach to managing the Cat Ba Biosphere Reserve because it offered a way to address components of sustainability holistically, while transcending organisational and disciplinary ‘silos’. Key features of the training approach include learning as a group of professionals, with senior organisational support and commitment to apply systems approaches in the workplace; enjoyable adult learning approaches tailored to the needs of participants; complementing teaching of systems thinking and techniques with participatory methods for working with the participants in developing solutions to their sustainability issues; and building in evaluation at every stage, through participatory methods taught in the course. The paper highlights the importance of teaching systems thinking and provides an example curriculum and teaching strategy based on adult learning principles. Copyright © 2011 John Wiley & Sons, Ltd.

Bruising or bleeding in a child can raise the concern for child abuse. Assessing whether the findings are the result of trauma and/or whether the child has a bleeding disorder is critical. Many bleeding disorders are rare, and not every child with bruising/bleeding that may raise a concern for abuse requires an evaluation for bleeding disorders. However, in some instances, bleeding disorders can present in a manner similar to child abuse. Bleeding disorders cannot be ruled out solely on the basis of patient and family history, no matter how extensive. The history and clinical evaluation can be used to determine the necessity of an evaluation for a possible bleeding disorder, and prevalence and known clinical presentations of individual bleeding disorders can be used to guide the extent of laboratory testing. This clinical report provides guidance to pediatricians and other clinicians regarding the evaluation for bleeding disorders when child abuse is suspected.

A remote sensing analysis of part of the Grenville Front is presented, following previous work east of Val d'Or, Quebec using ground geology, satellite imagery and magnetic data to reveal the front. In the study area, 110 km east of Senneterre, Quebec, Landsat and magnetic data were supplemented with data from a new ERS-1 satellite imaging radar which is sensitive to terrain topography and surface roughness. The data were enhanced using contrast stretch, directional and median filtering, shaded relief and the IHS (Intensity, Hue and Saturation) transform. The Grenville Front was located using structural trends based on field observations and coinciding with the boundaries of magnetic anomalies, linear waterways and lineaments enhanced on TM and ERS-1 radar data. The position of the Front was extrapolated in unmapped and till covered areas using magnetic contrasts of the vertical gradient data.
