Land cover and air pollution are associated with asthma hospitalisations:A cross-sectional study
BACKGROUND: There is increasing policy interest in the potential for vegetation in urban areas to mitigate harmful effects of air pollution on respiratory health. We aimed to quantify relationships between tree and green space density and asthma-related hospitalisations, and explore how these varied with exposure to background air pollution concentrations. METHODS: Population standardised asthma hospitalisation rates (1997-2012) for 26,455 urban residential areas of England were merged with area-level data on vegetation and background air pollutant concentrations. We fitted negative binomial regression models using maximum likelihood estimation to obtain estimates of asthma-vegetation relationships at different levels of pollutant exposure. RESULTS: Green space and gardens were associated with reductions in asthma hospitalisation when pollutant exposures were lower but had no significant association when pollutant exposures were higher. In contrast, tree density was associated with reduced asthma hospitalisation when pollutant exposures were higher but had no significant association when pollutant exposures were lower. CONCLUSIONS: We found differential effects of natural environments at high and low background pollutant concentrations. These findings can provide evidence for urban planning decisions which aim to leverage health co-benefits from environmental improvements
Transsexual Bodies at the Olympics: The International Olympic Committee's Policy on Transsexual Athletes at the 2004 Athens Summer Games
Sport exists on the premise that males and females are radically different. (Barnes, 2004) Thus sex gradually became an object of great suspicion; the general and disquieting meaning that pervades our conduct and our existence, in spite of ourselves; the point of weakness where evil portents reach through to us; the fragment of darkness that we each carry with us: a general signification, a universal secret, an omnipresent cause, a fear that never ends. (Foucault, 1978: 69) In May 2004 the International Olympic Committee (IOC) implemented a policy enabling transsexual athletes to compete at the summer Olympic Games in Athens. The IOC Medical Commission proposed that transsexual athletes who had Sex Reassignment Surgery (SRS) before puberty shall be admitted to compe-tition; that all other transsexuals must be post-operative (SRS including external genitalia and gonadectomy); must have legal and governmental recognition o
