高校师德评价指标体系研究

当前,高校都非常重视师德的建设,但在建设和评价的过程中,却因缺乏一套行之有效的师德评价指标体系而未能够对教师的师德表现实现公平、科学、高效的评价。为此,本文从高校师德评价指标体系的现状和师德的内涵着手进行分析,试图构建一套较为科学合理的评价指标体系．以期对高校师德评价工作起到一定的指导作用。     

人文社科领域科研项目立项评价的指标体系研究

人文社科领域科研项目的立项评价是项目选择和确定的重要依据,是项目进行的基础和前提,在项目评价过程中起关键作用.根据指标设计的基本原则构建了立项评价的指标体系,并设置了指标权重.为克服以往定性分析的不足,应用综合评分法将定性和定量相结合,描述了具体的计算过程,为科研项目的立项评价提供了一种简易可行的方法,对科研项目的实际操作具有重要的指导意义.     

环境管制与中国农业全要素生产率增长研究

利用中国省际面板数据,将农业面源污染和碳排放作为"坏产出"指标纳入农业全要素生产率测算中,采用Malmquist-Luenberger指数分析2001—2010年考虑环境因素下中国30个省市区的农业全要素生产率及其分解成分,并探讨考虑环境因素下中国农业全要素生产率演变的影响因素。研究结果表明:考虑环境因素的中国农业全要素生产率呈增长趋势,但表现出较大的波动性,其动力主要来源于技术进步;从地区差异来看,考虑环境因素下中国农业全要素生产率呈现东、中、西部地区依次递减;农村经济发展水平、农业产业结构变动、农业基础设施投资对考虑环境因素下中国农业全要素生产率有显著影响,而环境管制影响则不显著。     

社会组织评估机制创新初探

社会组织在我国发展迅速,在提供公共服务、增进社会公平、化解社会矛盾、反映社会不同阶级诉求、推进社会和谐发展等方面发挥了重要作用。随着社会组织的快速发展,社会组织评估成为必然的选择。本文从评估指标体系和评估实践两大方面对社会组织评估机制进行分析与研究,提出现存社会组织评估指标体系及评估实践的现状、不足以及相应的创新性改良,其中包括第三方评估机制应实现评估主体的多元化、评估方法与程序要坚持分类评估与统一评估相结合,以及完善评估法律法规制度的问题。     

企业家人口统计特征对中小企业融资约束的影响机制研究

基于高层梯队理论,以2010年我国530家中小上市企业为样本,采用层级回归方法,分析企业家人口统计特征对中小企业融资约束的影响及其作用机制。研究结果表明,企业家不同的人口统计特征对中小企业融资约束产生不同的影响,具体来说,企业家受教育程度和职称对缓解中小企业融资约束产生积极影响,企业家年龄和任期对中小企业融资约束产生显著的U型影响,而女性企业家对缓解中小企业融资约束产生消极影响。研究结果不仅丰富了企业家人口统计特征与中小企业融资约束之间的相关理论,并为缓解我国中小企业融资约束提供了实践支持。     

图书馆阅读文化建设与评价研究——以华东地区图书馆为例

图书馆阅读文化建设作为图书馆文化建设工程的有机部分,承担着凝聚、控制和导向等职能。本文参考图书馆文化建设的内容,主要从环境建设、资源建设、服务建设3个方面建立图书馆阅读文化评价指标体系,并对图书馆阅读文化建设的现状进行评价和分析,最后提出推动图书馆阅读文化建设的管理策略。     

课前准备活动的生理探讨

体育课的准备活动是课的重要组成部分之一,体育课的最大特点是学生直接从事大量的身体练习,而准备活动的目的在于逐步提高学生大脑皮层的兴奋性,逐步克服内脏器官的惰性,使人体各组织器官迅速进入工作状态,为基本部分的学习做好生理上和心理上的准备.

Determination of peak cardiorespiratory fitness parameters in children: which averaging method should we use?

The purpose of this study was to identify which averaging methods most accurately measures peak cardiorespiratory fitness (CRF) parameters [peak O₂ uptake (VO₂), peak O₂pulse and peak respiratory exchange ratio (RER)] in a sample of healthy children and adolescents. In this cross-sectional multicenter study, we recruited 278 healthy children aged 12–17 years. We compared the mean peak value of three CRF parameters using the recommended averaging methods (30-second block average) with alternative averaging methods such as moving averages or shorter smoothing periods. We also assessed averaging methods for accuracy by individually reviewing breath-by-breath scatter plots. The 30-second block average method resulted in a lower mean peak VO₂ and in an increased proportion of underestimated peak values. Using a 30-second moving average significantly increased mean peak values which increased accuracy. Similar results were found for peak RER and peak O₂pulse. In conclusion, the currently recommended averaging method (30-second block average) increased the risk of misinterpretation of peak CRF values in children. Using a moving average approach decreased misinterpretation and increased accuracy.     

Physical fitness of primary school children in relation to overweight prevalence and physical activity habits

Abstract

A cross-sectional study was carried out to analyse, through a limited number of fitness tests, the main conditioning and coordinative abilities in children aged 8–9 years, and their relationship with gender, anthropometric variables and physical activity habits. The height and weight of 256 boys and 241 girls were measured and information about physical activity habits was collected using a self-administered questionnaire. Physical performance was assessed by means of a few standardised tests: ‘sit & reach’, medicine-ball forward throw, standing long jump, 20 m running speed, and forward roll test. In both boys and girls, body weight and Body Mass Index (BMI) were positively correlated with the medicine-ball throw performances and negatively correlated for the standing long jump and speed tests, while no association was found with tests measuring back flexibility and total body coordination. Daily physical activity and participation in sport were not significantly correlated with body weight and BMI, but were positively associated with children's motor performance. The standardised fitness tests selected in the current study have been found to be suitable to identify fitness levels of primary school children. Thanks to their limited number and ease of measurement, they can be used in any school context to classify children and for monitoring the effects of targeted interventions promoting physical activity.
