马拉松赛事风险政府协调治理的理论内涵、现实困境与实现路径

研究以政府协调治理为理论基础,以“主体-场景-行动”为治理逻辑的分析框架,指出马拉松赛事风险治理的困境,提出马拉松赛事风险政府协调治理的实现路径。研究认为,马拉松赛事风险治理存在治理主体对赛事风险治理认识不够、赛事风险场景的精细划分比较笼统、赛事风险应急合作治理行动的基础支撑条件不完善等困境。应从更新治理理念、转变治理主体的角色认识,优化场景划分、夯实场景的精细化和数字化;强化行动效益,夯实赛事风险治理的行动基础3个方面推进治理。     

The validity and reliability of a sample of 10 Wattbike cycle ergometers

ABSTRACT

The purpose of the study was to assess the validity and inter-bike reliability of 10 Wattbike cycle ergometers, and to assess the test–retest reliability of one Wattbike. Power outputs from 100 to 1000 W were applied using a motorised calibration rig (LODE) at cadences of 70, 90, 110 and 130 rev · min^?1, which created nineteen different intensities for comparison. Significant relationships (P < 0.01, r² = 0.99) were found between each of the Wattbikes and the LODE. Each Wattbike was found to be valid and reliable and had good inter-bike agreement. Within-bike mean differences ranged from 0.0 W to 8.1 W at 300 W and 3.3 W to 19.3 W at 600 W. When taking into account the manufacturers stated measurement error for the LODE (2%), the mean differences were less than 2%. Comparisons between Wattbikes at each of the nineteen intensities gave differences from 0.6 to 25.5 W at intensities of 152 W and 983 W, respectively. There was no significant difference (P > 0.05) between the measures of power recorded in the test–retest condition. The data suggest that the Wattbike is an accurate and reliable tool for training and performance assessments, with data between Wattbikes being able to be used interchangeably.     

The Persuasive Influence of Nollywood Film in Cultural Transmission: Negotiating Nigerian Culture in a South African Environment

The popularity and viewership of Nollywood films have expanded across African and Western cities especially those with considerable Diaspora population. This study seeks to investigate whether watching Nollywood films is likely to lead to cross-cultural transmission of Nigeria’s cultural heritage to audience members in South Africa. Data for the study were collected using observation and surveys with Likert-type scales involving participants from a South African college. Results show that watching Nollywood films was significant in increasing participants’ knowledge and appreciation of Nigerian culture. Observed patterns indicate that a small portion of participants could mimic or reproduce some common Nigerian expressions and exclamations while a negligible percentage of participants could actually speak a smattering of Igbo, one of Nigeria’s three major languages.     

A novel sleep optimisation programme to improve athletes’ well-being and performance

Objectives: To improve well-being and performance indicators in a group of Australian Football League (AFL) players via a six-week sleep optimisation programme. Design: Prospective intervention study following observations suggestive of reduced sleep and excessive daytime sleepiness in an AFL group. Methods: Athletes from the Adelaide Football Club were invited to participate if they had played AFL senior-level football for 1–5 years, or if they had excessive daytime sleepiness (Epworth Sleepiness Scale [ESS] >10), measured via ESS. An initial education session explained normal sleep needs, and how to achieve increased sleep duration and quality. Participants (n?=?25) received ongoing feedback on their sleep, and a mid-programme education and feedback session. Sleep duration, quality and related outcomes were measured during week one and at the conclusion of the six-week intervention period using sleep diaries, actigraphy, ESS, Pittsburgh Sleep Quality Index, Profile of Mood States, Training Distress Scale, Perceived Stress Scale and the Psychomotor Vigilance Task. Results: Sleep diaries demonstrated an increase in total sleep time of approximately 20?min (498.8?±?53.8 to 518.7?±?34.3; p?<?.05) and a 2% increase in sleep efficiency (p?<?0.05). There was a corresponding increase in vigour (p?<?0.001) and decrease in fatigue (p?<?0.05). Conclusions: Improvements in measures of sleep efficiency, fatigue and vigour indicate that a sleep optimisation programme may improve athletes’ well-being. More research is required into the effects of sleep optimisation on athletic performance.     

13th China Wuqiao International Acrobatic Festival Concluded with Great Success

From October 22 to 30, 2011, the 13th China Wuqiao Acrobatic Festival was held in Shijiazhuang, north China’s Hebei province.Co-organized by the Ministry of Culture of China and Hebei People’s Provincial Government, this biennial event featured the theme of "developing acrobatic art, facilitating international exchanges,promoting economic and social development,and enriching people’s cultural life". This year,the festival attracted more than 200 acrobats from 27 circus companies from 17 countries and regions around the world, including Russia,Canada, USA, DPRK, Australia and France, who
