国家队管理模式的研究 总被引:1,自引:0,他引:1
目前我国国家队管理模式种类较多,其中集体领导方式占多数,但不同项目管理模式选择有一定差异,不同管理模式也存在各自的优劣势.对不同项目队的分析表明,模式选择受多因素影响,尤其与运动队权威领导的个人素质和项目特点有关.因此不同项目国家队管理模式的选择要考虑多方面因素.建议多数国家队要采取队委会领导下的分工负责制,特殊项目要根据具体情况做出选择.但不同管理模式在实际运行过程中要注意解决好不同的问题. 相似文献

Adverse Childhood Experiences (ACEs) are prevalent in the population and linked to various negative long-term health and social consequences. However, due to the retrospective nature of most studies on the topic, little is currently known regarding ACEs' immediate health impact. This study aims to provide insight into this area by examining the association between a new measurement, Adverse Family Experiences (AFEs), and flourishing amongst children ages 6–17 years in the United States. Data from the 2011/12 National Survey of Children's Health were analyzed. Adjusted prevalence ratios assessed flourishing by the number of AFEs (0 events versus 1, 2, 3/3+) controlling for individual/household characteristics. A sub-analysis examined characteristics of flourishing children ages 12–17 years with 3/3+ AFEs. The results showed children with 1 AFE (APR = 0.87; 95% CI = 0.83-0.91), 2 AFEs (0.74; 0.69–0.79), and 3/3+ AFEs (0.68; 0.62–0.72) were less likely to flourish compared to those without any AFEs. Sub-analysis of children ages 12–17 years with 3/3+ AFEs revealed a higher proportion of flourishing children volunteering, participating in extracurricular activities, and working for pay compared to those who did not flourish. Findings show significant differences in flourishing by number of AFEs and suggest that social connectedness may play a role in determining flourishing amongst children with 3/3+ AFEs. Furthermore, the results highlight the potential importance of identifying children with high AFE counts and helping them build resilience outside of the home. 相似文献

This study analysed The 8th Online Survey of Adolescent Health and Behaviour in 2012, which is a government-approved statistical survey of Internet use and patterns in Korea. We conducted a propensity score matching (PSM) to control for economic status differences between monocultural and multicultural families and an ANOVA to estimate the effects of multicultural family status, adolescents’ gender, school grades, locality, and parents’ academic background on adolescents’ Internet use (for studying and entertainment). The study revealed the following: with regard to Internet use patterns, adolescents from both monocultural and multicultural families selected gaming as their first choice, followed by studying and data searching. Furthermore, main and interaction effects of independent variables on adolescents’ time spent on the Internet for studying were not significant. However, the interaction effects of multicultural family status and mothers’ academic background on adolescents’ time spent on the Internet for entertainment were statistically significant. Specifically, adolescents’ time spent on the Internet for entertainment was higher in multicultural families with mothers whose education level was lower than middle school. Finally, we suggested that the government should provide full support to less educated mothers in multicultural families for effectively and constructively controlling their children’s Internet use and teaching it to them. 相似文献

Baseline data available on the excretory profiles of estrone giucuronide (E1G), pregnanediol glucuronide (PdG) and luteinising hormone (LH) on human menstrual cycles (n=104) was retrospectively analysed
for identifying the limits of fertile period (FP) to be used as natural method of family planning. The limits of fertile period
are suggested based on centile distribution of E1G and PdG levels during defined phase of menstrual cycle. Two approaches, which do not involve any mathematical calculation
are suggested. In approach A, fertile period is said to have started when E1G value of 35 ng/ml is reached and is said to have ended when the PdG value of 2 μg/ml on two consecutive days is obtained.
The criteria were applied to 30 test cycles in whom authentic fertile period was identified based on excretory profiles of
E1G, PdG and LH throughout the menstrual cycles. When approach A was followed the authentic fertile period was covered in 27
cycles giving an accuracy of 90% with a mean fertile period length of 9.11+1.9 days. In approach B, the cut off limit of E1G value was increased to 55 ng/ml in order to reduce the days of abstinence. Though the length of the fertile period was reduced
to 7.2+1.5 days the accuracy of the approach was 66.6%. Thus the approach A which has accuracy of 90% may appeal to determined
couples who wish to practice family planning by periodic abstinence or restrict the use of barrier methods. 相似文献
