AbstractRussia’s (and the USSR’s) use of sports mega-events (SMEs) makes this BRICS country (Brazil, Russia, India, China, and South Africa) not only an outlier among emerging states, but also among key SME hosts generally. Both the historic Moscow Olympics (1980) and the more recent hosting of the 2014 Sochi Winter Olympics provide evidence that Russia has, on both occasions, focussed on geopolitical priorities using hard power (military might) at the expense of soft power acquisition. Furthermore, both Olympics were, first and foremost, used to pursue domestic soft power goals. This, again, makes Russia an outlier in terms of the political use of SMEs by states in the literature on this subject. The 1980 Olympic Games, therefore, in terms of their potential to generate soft power and national unity, turned out to be a mis-used opportunity for Russia. To what extent is this specific to Russia and could the first Russian Olympics provide valuable insight into the modern-day hosting of SMEs by Russia (2014/2018)? 相似文献

The game of darts attracts a large international following and can be fiercely competitive. Despite its popularity, and the large equipment market, no previous peer-reviewed studies have examined the trajectory of a dart in flight. This study used high-speed video techniques to measure the trajectories of 225 dart throws from 19 amateur players. The dart’s pitch and angle of attack were found to oscillate during flight in a manner that is analogous to damped harmonic motion. It was also found that the dart’s oscillation frequency was strongly correlated to launch speed, whilst its characteristic wavelength and damping ratio were independent of launch speed. The measured wavelength of oscillation (2.16 m) was found to be similar to the regulation throwing distance (2.37 m). It is proposed that the dart is ‘tuned’ to the throwing distance such that it undergoes one full oscillation before striking the board. The dart flight was modelled using a classical dynamic stability analysis and good agreement was found between the experimental observations and the theoretical predictions. The success of the model confirms that the approach can be used to explore the dynamics of different dart designs through parametric sensitivity analyses. 相似文献

The last two decades within Australia have witnessed a range of policies and strategies seeking to promote the inclusion of young people with disabilities within mainstream community sport clubs. Whilst research at an institutional level has highlighted the problems with mainstreaming agendas, few studies have examined how grassroots clubs, as key components of the supply side of inclusive provision seek to respond to such policy imperatives. In this paper, therefore, the authors provide a critical analysis of the ways in which clubs engage with inclusion policies in practice. Theoretically, the authors draw on the concept of policy enactment and educational inclusivity. Through analysis of semi-structured interviews with club volunteers, the findings illustrate three key areas. Firstly, the importance of individual volunteers in establishing and developing provision within clubs; secondly, the largely separatist nature of disability provision within clubs; and thirdly, that policies tend to encourage club to focus on narrow forms of participation that lead to competitive pathways and mirror the structure of mainstream sport. In the conclusion, the authors problematize the notion of inclusion presented in policy and practice, suggesting such imperatives do not encourage a holistic approach. 相似文献

There is a paucity of research on devices suitable for home-based isometric exercise. Our aim was to compare cardiovascular responses to isometric exercise using novel and established methods. Ten individuals (age 34.0 +/- 8.5 years, mass 68.2 +/- 10.4 kg, height 1.72 +/- 0.09 m; mean +/- s) performed three different isometric exercise protocols with 48 h between each. Each protocol involved four repeated exercise bouts of 2 min at 30% maximum voluntary contraction force using alternate legs (transducer), alternate arms (transducer), or alternate arms (novel device). Systolic blood pressure, diastolic blood pressure, mean arterial blood pressure and heart rate were measured every 30 s. The highest (peak) values during each 2 min bout of exercise were recorded (peak systolic blood pressure, peak diastolic blood pressure, peak mean arterial blood pressure and peak heart rate). At the end of each 2 min exercise bout, the participants rated their perceived discomfort using Borg's CR-10 scale. There was a statistically significant difference in peak systolic blood pressure between isometric arm flexion using the force transducer and the novel device [158.1 +/- 10.8 vs. 149.1 +/- 13.9 mmHg (mean +/- s); P = 0.02]. Further analysis showed that peak systolic blood pressure was on average 9 mmHg higher using the force transducer with limits of agreement of - 15.97 to 33.97 mmHg. Analysis of the peak diastolic blood pressure, peak mean arterial blood pressure, peak heart rate and CR-10 data revealed no statistically significant differences between the three protocols. These results suggest that this novel, home-based method elicited similar cardiovascular responses during isometric exercise to those of established laboratory-based methods. However, the lower peak systolic blood pressure using the modified scales warrants further investigation before this method is used widely in the home. 相似文献

Objective: To predict the possible accomplishments of the Evidence‐Based Librarianship (EBL) movement by the years 2005, 2010, 2015 and 2020. Methods: Predictive. The author draws upon recent events, relevant historical events and anecdotal accounts to detect evidence of predictable trends. Results: The author develops a set of probable predictions for the development of EBL. Although incomplete evidence exists, some trends still seem discernible. Conclusion: By 2020, EBL will have become indistinguishable from mainstream health sciences librarianship/informatics practices. 相似文献
