Sex differences in exercise and drug addiction: A mini review of animal studies

Growing literature has demonstrated that exercise may be an effective prevention and treatment option for drug addiction. In the past few years, many studies have suggested that there were sex differences in all phases of drug addiction. However, very limited research has investigated sex differences in the effectiveness of exercise intervention in drug addiction and rehabilitation. In this mini review, we summarize the effect of sex on the results of using exercise to prevent and treat drug addiction. The studies we consider span various animal models and use multiple types of exercise to examine the effectiveness of exercise on the neurobiological mechanism of exercise rehabilitation. We believe that exercise as an adjuvant intervention strategy can be applied better in drug addiction prevention and recovery.

Power and discourse in the politics of evidence in sport for development

The field of sport for development (SFD) has been criticised for the way that evidence has been produced and used to account for and demonstrate the perceived success of SFD programmes. Much of this critique has highlighted shortcomings in approaches to monitoring and evaluation (M&E), which underpins a perceived weak evidence base concerning what works, why and within which contexts (Coalter, 2007, Coalter and Taylor, 2010, Pawson and Tilley, 1997). Conceptually a lack of evidence discourse (Nicholls et al., 2010) has emerged. This paper explores and analyses the power dynamics that shape this discourse and argues that an understanding of the dominant neoliberal context within which SFD is located is critical. While offering a Foucauldian framework, the power, knowledge and discourse related to political actors in SFD processes are examined. This paper addresses two key questions: what is power and who is it for? Whose interests are served in the interpretation, generation and reporting of evidence? The paper concludes that the role of the sport development practitioner (SDP) is underprivileged and to enable the field of sport for development (SFD) to move forward, the very people who implement the programmes need to be better understood. Furthermore it is argued that a deeper understanding and interpretation of the terrain of the sport development practitioner (SDP) within UK and international shores are a necessity if a more open and transparent knowledge transfer process, surrounding evidence, is to be entered into.     

基于遗传蚁群算法的电厂主蒸汽温PID参数优化与控制仿真研究

大型火电厂的主蒸汽控制系统是保障锅炉稳定运行的,提高发电效率的主要设备。以传统PID为基础的常规控制系统已无法适应越来越高的现代化高效率生产的要求。本文利用遗传蚁群算法从控制论的角度出发对PID参数优化进行研究,动态调整电厂主蒸汽锅炉的蒸汽温度PID参数。仿真实验结果表明,该方法提高了系统的鲁棒性,且具备良好的经济运行效益,有一定的推广价值。

The Transformation of China's National Fitness Policy: From a Major Sports Country to a World Sports Power

For most countries with developed economies, the increasing prevalence of a sedentary lifestyle has led to a decline in adolescents' physical fitness and increased risk of chronic disease and obesity. A common solution to this problem has been to encourage greater youth participation in sports and physical activities. However, there is little evidence to suggest that this approach has been successful. Since the 1984 Los Angeles Olympic Games, the development of elite sports in China has received increasing attention, reaching its climax during the Beijing Olympic Games, where China won the most gold medals. According to a study undertaken by Dong Xinguang, who designed the ‘Outline of the National Fitness Program,’ China's success in elite sports has, to some degree, been built at the expense of the country's national fitness. This study focuses on the sport-for-all policy change, especially the changes to the Peoples Republic of China's (PRC) national fitness policy after an official speech delivered after the 2008 Beijing Olympic Games by the president of the PRC, Hu Jintao, who, for the first time, mentioned the idea of ‘changing from a major sports country to a world sports power.’ In an attempt to help assess the extent of change in China's national fitness policy, this study adopts the five policy change indicators (comprising organization, statutes, budget, personnel, and the media) developed by Hogwood and Peters and Juang. Furthermore, elite theory is adopted as our analytical framework to explain how the political elites have tackled the difficulties in promoting sports in China. Finally, our findings are presented in three parts: the driving forces behind the policy change, policy change reflected in the five dimensions, and the conclusion.
