Exercise Motivation of College Students in Online,Face-to-Face,and Blended Basic Studies Physical Activity and Wellness Course Delivery Formats

Abstract

Objective: The purpose of this study was to assess exercise motivation among college students self-selected into 4 online (OL) and face-to-face (F2F) basic studies’ physical activity and wellness course delivery formats. Participants/Methods: Out of 1,037 enrolled students during the Spring 2009 semester, 602 responded online to demographic questions and to the Behavioural Regulation in Exercise Questionnaire, which assessed exercise motivation on 5 subscales. Results: There were no significant differences (p > .05) in exercise motivation for students across course delivery formats, but there was a significant difference in age and employment status between the completely OL and F2F course formats. Conclusions: Health and physical educators can utilize these findings to better understand that physical activity and wellness students are not necessarily trying to avoid physical activity when selecting the OL course format, but are more likely trying to balance work and school responsibilities and need greater flexibility in time and location.     

投服中心行权与企业会计稳健性

保护中小投资者利益是中证中小投资者服务中心(以下简称“投服中心”)的重要职责,会计稳健性能够起到风险预警和缓冲的作用,关乎投资者利益能否得到有效保障。基于2013—2021年我国A股上市公司及投服中心行权数据,采用多时点双重差分模型,研究了投服中心行权对被行权企业会计稳健性的影响。研究发现,投服中心行权能够提高被行权企业的会计稳健性;代理成本的降低和信息不对称的缓解是投服中心行权影响企业会计稳健性的主要渠道。调节效应分析表明,信息中介在投服中心行权与会计稳健性的关系间发挥了负向调节作用,即当分析师关注度、媒体关注度以及机构投资者持股比例较低时,投服中心行权对会计稳健性的提升效果更明显。异质性分析表明,投服中心行权对会计稳健性的提升效应仅显著存在于大股东掏空严重、负债水平高、成长性差以及产权性质为非国有的企业中。进一步研究发现,投服中心行权能够提高会计盈余确认“坏消息”相较于“好消息”的增量及时性。因此,政府应进一步完善投资者保护组织体系,充分发挥投服中心的作用,助力企业提高会计信息质量,夯实资本市场根基,更好地推动资本市场高质量发展。     

Differentiating the time-geography of recreational running

ABSTRACT

This paper proposes a relational time-geography approach to differentiate the geographies of recreational activities, whose place cannot be pinned down to a single specific infrastructure or area and therefore risks being marginalised in planning. Running is used as a case study. Based on diary-interviews, we have identified three different exercises/places used alternately by the respondents: the forest run; ‘the most boring route in the world’; and the tourist run. We argue that the time-geography of runners could be conceptualised as a rhythm of place dependencies, where different places afford complementary qualities. By allowing for a negotiation of the spatio-temporal constraints of everyday life, these different places (and their affordances) are of crucial importance for motivation and exercise.     

A Population-Based Study of Coupling and Physical Activity by Sexual Orientation for Men

ABSTRACT

Research has suggested that men in relationships are more physically active than men who are single. This study provides a weighted analysis of physical activity by coupling status for men of different sexual orientations. Aggregated data from the United States 2013–2014 National Health Interview Survey were used to conduct multivariate logistic regression analyses. Compared to straight men (n = 29,926), gay men (n = 623) were less likely to be in a relationship (AOR 0.32, CI: 0.25–0.41). Coupled gay men did more physical activity than coupled straight men and were 1.62 (CI: 1.05–2.50) times more likely to be active, 1.67 (CI: 1.10–2.51) times more likely to be high active, 1.89 (CI: 1.24–2.89) times more likely to engage in muscle-strengthening activities, and 2.00 (CI: 1.28–3.11) times more likely to meet aerobic and muscle-strengthening recommendations. Coupling facilitates physical activity for men. However, more research is needed to help explore underlying mechanisms for differences by sexuality.     

增长期权的执行、创造与资产风险溢价——企业生命周期的视角

增长期权的执行和创造共同推动着企业的生命周期进程,二者对资产相对构成的影响力量对比决定了资产风险溢价随企业生命周期的变化特征。本文在连续时间框架下利用实物期权方法和定价核技术,理论上揭示并比较增长期权执行和创造对资产风险溢价的影响,以及二者共同作用下资产风险溢价随企业生命周期的变化规律。结果表明：增长期权的执行和创造分别会降低和提升风险溢价,且二者分别对年轻和成熟阶段资产风险溢价的影响更大;进一步,增长期权的不断执行使得资产风险溢价随企业生命周期进程呈现下降趋势,增长期权的持续创造则可使成熟企业"再焕新生"而进入新的生命周期。     

探讨长期有氧运动对老年2型糖尿病患者的降糖效果

目的针对老年糖尿病患者,年龄大、慢性并发症多、不适合大强度运动的特点,观察长期适度的、规律的有氧运动对老年糖尿病患者血糖的影响。方法选择106例老年2型糖尿病患者,随机分为运动组和非运动组进行对比,观察运动前后体重指数（BMI）、空腹血糖、餐后2小时血糖、糖化血红蛋白的变化,并与未进行有氧运动治疗的53例患者对照比较。结果 40周后运动组的体重指数、空腹血糖、餐后2小时血糖、糖化血红蛋白均明显降低,而非运动组各项指标均无明显差异。结论长期规律的、适度的有氧运动,能明显降低老年2型糖尿病患者的体重指数、空腹血糖、餐后2小时血糖、糖化血红蛋白。因此,对于老年2型糖尿病患者来说,长期规律的、适度的有氧运动与长期的药物治疗有等同的意义。     

高校健美教学中应用运动处方的实验研究

和谐理念下的体育教学探析

体育课程改革应摆脱传统狭隘体育思想的束缚,坚持＂健康第一＂的教学理念,发挥学生的积极性和潜能,实现＂教＂＂学＂共鸣、良性互动的和谐体育教学。教师需转变观念、优化教学内容、创新教法带动学法创新、改进教学评价,促进教学环节的和谐循环,从而形成较为稳定的和谐体育教学模式。     

中非追缴腐败犯罪违法所得的国际司法协助

随着经济全球化以及中非政治、经济交往的增加,腐败犯罪违法所得在中非之间的跨境转移也必然呈现上升态势,因此,中非之间在追缴腐败犯罪违法所得领域的合作变得非常迫切。虽然中非在此领域的合作还刚刚开始,但是《联合国反腐败公约》、《非洲联盟关于预防和打击腐败公约》及《中华人民共和国对非政策》已为中非打击腐败、追缴腐败犯罪违法所得合作确立了依据。中非之间在此领域的合作要遵循主权原则,同时要在主权的行使方面保持适度的灵活性,在双层合作的框架下推动在此领域内双边或多边条约的缔结。
