全民健身运动对高校课外体育活动体系构建的影响

组织与开展高校课外体育活动,是学校满足学生参与体育实践活动的需求、促进自身体育素质能力提高与发展的重要手段。为了适应以全民健身运动为核心的社会体育发展的主流形式,高校课外体育活动体系的构建应以全民健身运动为导向,在内容与形式上,与全民健身运动的发展需求达成有机的一致性与相融性,这对于促进高校体育教学改革的发展,具有极其重要的现实意义。     

学人的“历史感”与新时期文学的“发难”问题及其他——兼与陈冲先生商榷

"新时期文学"的命名意味着处于"新时期"的当代文学的性质、意义均与文艺界和学界对于"文革"这段历史的质问责难相关,把新时期文学质诘"文革"最激烈的第一个10年(1976-1985)界定为"发难期",可以更为准确地认知这一文学实践的性质,尤其是可以强化先贤们反思和批判"文革"的历史意义。新时期文学仍然受"向前看"的新政治意识形态的制约,其背后一直存在着政治意识形态的"规训"等问题。正确审视新时期文学发难期的实绩要从最基本的阅读感受出发。     

“现代”中国文学史——读钱基博《现代中国文学史》

与后来的文学史以建构科学客观的知识学为目的不同,钱基博以传统子、史精神“撰著”《现代中国文学史》,将王阁运、章太炎、康有为、陈三立、严复、王国维、梁启超、胡适等并置一起,讨论他们如何以各自的理论见解和创作实践共同参与和见证“现代”这一“事件”。梁启超、胡适倡导“革命”,追求文学日新叉新的“现代”;章太炎则代表着第二种“现代”人物类型,身预追新求变的“现代”潮流,却自始即长虑却顾,意识到必将随新变而来的种种流弊;《现代中国文学史》着墨最多也是人数最多的是第三类人物,康有为、陈三立、严复、王国维、章士钊等人包括著者钱基博自己,他们始则舍旧谋新惟恐不力,晚则痛加追悔。一部《现代中国文学史》堪称三类“现代”文人之“忏悔录”。

Biochemical markers of bone metabolism in healthy elderly men. The relationship to physical activity

The purpose of the present study was to examine the serum levels of bone turnover markers and interleukin 1β in healthy elderly men with different levels of habitual physical activity. The study was conducted on 40 healthy men aged between 65 and 85 years (mean 74.0?±?7.55 years). The study population was divided into two groups with respect to the level of physical activity: 22 less active subjects (energy expenditure related to physical activity below 1600?kcal per week) and 18 more active subjects (above 1600?kcal per week). To estimate the physical activity of the study population, weekly energy expenditure was measured in each subject with use of Caltrac accelerometer. In the blood serum levels of bone formation marker – osteocalcin and resorption marker – the C-terminal telopeptide of collagen I (ICTP), and interleukin-1β were determined. Concentrations of osteocalcin and ICTP in less active subjects were significantly higher (by 3.62?ng/ml and by 1.21?μg/l respectively, p?<?0.05), reflecting the higher bone turnover in comparison to values determined in more active subjects. Positive correlations between ICTP and osteocalcin levels (r?=?0.5814 and r?=?0.6526; p?<?0.05), and between ICTP and IL-1β (r?=?0.5823 and r =?0.6040; p?<?0.05) in less and more active men were found. On the ground of the presented study it can be concluded that the decreased bone turnover occurred in men with higher level of habitual physical activity. This study showed the relationship between serum level of IL-1β and bone resorption but the habitual physical activity has no effect on this cytokine activity.     

Our common future: a rapidly growing and rapidly aging humankind

Abstract

Physical inactivity, diabetes, hypertension, dyslipidemia, smoking and obesity were associated with imbalance in oxidative stress, leading to endothelial dysfunction. Such dysfunction is present in both cardiovascular disease (CVD) and erectile dysfunction (ED). ED is the persistent inability to achieve or sustain an erection sufficient for satisfactory sexual performance and is one of the first manifestations of endothelial damage in men with CVD risk factors. The purpose of this article is to review the results of studies involving physical activity, CVD, endothelial dysfunction and ED in order to verify its applicability for improving the health and quality of life of men with such disorders. There is consistent evidence that endothelial damage is intimately linked to ED, and this manifestation seems to be associated with the appearance CVDs. On the other hand, physical activity has been pointed out as an important clinical strategy in the prevention and treatment of CVDs and ED mainly associated with improvement of endothelial function. However, further experimental and clinical prospective investigations are needed to test the role of physical exercises in the modulation of endothelial function and their implications on erectile function and the appearance of CVDs.     

Browsing the culture: membership and intertextuality at a mormon bookstore

This paper argues that organizational and local host cultures are related through the intertextual performance of membership. It proceeds by claiming that organizations may be usefully read as intertexts, and that the relationship between organizations and their environments is enacted by speakers as they negotiate their multiple identities in talk. These claims are then used to analyze the intertextual performance of membership at a Salt Lake City, Utah bookstore owned by the Mormon church. The analysis demonstrates how: (1) organizational routines surrounding the interpretation of product serve as performances of host-cultural membership; (2) communication among and between store employees and customers clarifies types of host-cultural identity; and (3) the management of controversial texts enacts the organizational environment. The analysis is intended to mark an intersection between organizational and cultural studies by demonstrating how organizations potentially function as sites for the reproduction of interpretive communities, conducted through the use of cultural texts.     

The Influence of the Built Environment and Other Factors on the Physical Activity of Older Women from Different Ethnic Communities

ABSTRACT

Inactivity has been identified as a major contributor to the burden of disease in older women. Study aims were: (a) to assess the personal, social, and environmental facilitators and impediments to physical activity in older women from ethnic communities; and (b) to determine the factors associated with physical activity participation. Older women (aged 60–84 years) were recruited from the local Italian (n = 20), Vietnamese (n = 26) and Anglo-Celtic (n = 26) communities. A survey questionnaire was administered in the participants' preferred language. The most common barriers were: “I am not in good health,” “I am self-conscious about my looks,” “I am too tired,” “I don't have time,” and “The weather is bad.” When comparing the ethnic groups, the Vietnamese women reported fewer barriers than the Italian women (2.6 vs. 5.9). While the Vietnamese women were much more likely to report being “self-conscious about my looks,” the Italian women more commonly reported poor health, being too tired, and not liking exercise as barriers. Overall, those living alone were more likely to be active and those who reported fear of injury, less active. Recognizing ethnospecific differences in the prevalence of barriers may be important when devising strategies to increase activity levels of older women.     

因“裁”施教——“外国文学史”教学初探

注重知识传授的传统的＂外国文学史＂教学模式忽视了对学生阅读文本的要求,因此改变传统的教学模式,激发学生阅读文本的兴趣就成了当务之急。传统的教学对诗歌、戏剧、小说等不同体裁作品都采取同一个模式,应从不同的文学体裁采取不同的教学方法入手,来激发学生的阅读兴趣,提高学生的文学能力与人文素养。     

复杂不确定环境下活动可拆分的项目资源鲁棒性调度优化

复杂不确定环境下,制定一个具有较强抗干扰能力的基准进度计划非常必要。本文研究了活动工期不确定环境下考虑活动可拆分的项目资源鲁棒性调度优化问题,旨在考虑活动可拆分,探究在活动优先关系约束、项目截止日期约束、活动拆分约束、资源流约束等条件下如何进行活动拆分决策并合理地安排各个项目活动/活动分段间的资源调配方案和时间缓冲添加策略,以制定鲁棒性最大化的基准进度计划。本文创新点如下：1)在项目资源鲁棒性调度优化问题中考虑活动可拆分,定义了资源流网络下活动自由时差的计算方法,提出了一种新的活动可拆分情形下进度计划鲁棒性的衡量方式,进而构建得到了考虑活动可拆分的项目资源鲁棒性调度优化模型;2)分析证明了问题模型的强NP-hard属性以及非线性属性,并在此基础上开发了一种内嵌资源调度安排的遗传算法进行问题求解;3)选取一个典型的实际案例对研究问题进行说明,直观展示了活动拆分执行对进度计划鲁棒性提升的重要价值,揭示了鲁棒性调度计划中资源调度方案的重要性,得到了活动拆分执行会增加项目内部资源转移次数的结论。
