Effect of magnetic insoles on postural sway measures in men and women during a static balance test

Numerous anecdotal reports have suggested a growing public enthusiasm for magnetic devices for treatment of pain and various motor and sensory dysfunctions. Although the principles behind magnetic therapy are well documented, a complete technical explanation of whether static magnet application is effective is lacking due to a paucity of scientific research. In this study the effectiveness of magnetic insoles on postural sway measures during a single application were investigated. Twenty-eight adults (14 old, 14 young) were assessed on postural sway measures while performing a static two-legged stance test on a Kistler force platform under two treatment conditions (magnetic insoles, nonmagnetic insoles). Significant reductions in total sway area and lateral sway scores were obtained by the older adults while standing on the magnetic insoles. These preliminary results indicate that treatment of postural instability using magnetic insoles may be a viable alternative for older adults.     

Using Force: Australian Newspaper Depictions of Contacts Between the Police and Persons Experiencing Mental Illness

The media creates and sustains knowledge about socially relevant issues such as crime, mental illness, and policing. Past research suggests that while the media portrayal of the police is undoubtedly complex, their portrayal of people experiencing mental illness remains mainly negative. The depiction of their encounters in the mass media is of considerable interest because of the influential role the media has on public opinion and debate; however, there is a lack of current research in this area. This study aimed to examine media items in the major newspapers across Australia between January 2006 and December 2007 (n = 77) to investigate their portrayal of this interface. The dominant themes encountered in the initial analysis depicted people experiencing mental illness as dangerous and a threat to the public, where the mental health system has failed to manage them adequately. Further analyses found that people experiencing mental illness were stigmatised in a third of the media items reviewed and were represented significantly more negatively in these encounters than the police. Implications of these findings and some suggestions regarding possible strategies that could improve socially responsible media reporting and public discourse on mental illness are proposed.     

熟悉性对外群体同质性效应的影响

两个实验考查了年龄和性别群体中是否存在外群体同质性效应以及熟悉性对该种效应的影响。结果表明：1．年龄群体中存在明显的外群体同质性效应,这与青年群体和老年群体彼此不够熟悉有关;2．性别群体中不存在外群体同质性效应,这与青年男女群体彼此较为熟悉有关。
