高三复习阶段的试卷讲评课是教学的重要组成部分,高效的试卷讲评课对于学生的知识和能力的提升具有重要意义。教师要充分利用好课前、课堂和课后三个板块的时间组织试卷讲评课,在各个时间板块中具体落实相应的准备、评析、巩固等环节,并贯彻各种教学和教育原则,形成高效的试卷讲评课,提升教学效果。     

2013年世界女排大奖赛总决赛中国队与巴西队技战术运用分析

2013年世界女排大奖赛总决赛中、巴之战是2008年以来,中国女排第13次落败于巴西队,为什么总是遇巴而败,为什么一传到位率在举国体制下的中国仍旧成为战败的主要问题;为什么面对欧美高大进攻队员仍旧势单力薄,单人拦网率居高不下;为什么丰富全面的战术预案下,调整球永远是公诸于众的四号位强攻,通过比赛录像的分析统计,运用文献资料法、数理统计法、对比分析等方法,探秘中、巴怪圈,欲透过表象探析问题的本质,从根本上寻求切实有效的方式方法。作者认为,不论是差距的寻找,还是问题的解决,都需要从事物的根本性质进行分析,需要对主体内因进行剖析。排球运动的项目属性及根本特征才是决定战术打法、训练理念及比赛宗旨的根本,而主体的培养体制、训练环境,以及认知理念才是比赛结果的主要原因。     

Metabolic response to 6-week aerobic exercise training and dieting in previously sedentary overweight and obese pre-menopausal women: A randomized trial

BackgroundThe aim of this study was to compare 6 weeks short-term moderate intensity aerobic exercise and dieting on serum metabolomics and cardio-metabolic risk factors in pre-menopausal women.MethodsNinety previously inactive overweight and obese (BMI 25–35 kg/m²) women (age 41.5 ± 7.6 years) were randomized to either a 6-week Nordic walking exercise program (EX, n = 45) or dietary counseling group (DI, n = 45). Body composition, serum glucose, insulin and lipids were measured. Serum low-molecular-weight metabolites and lipid constituents were analyzed by nuclear magnetic resonance spectroscopy. Measurements were done at baseline and 7 days after the last training session.ResultsSix weeks aerobic exercise program yielded reductions in serum free fatty acids (−34.7%, 95% confidence interval (CI), −50 to −18, p < 0.001), glucose (−9.6%, 95%CI, −15 to −4, p < 0.001) and homeostasis model assessment of insulin resistance (HOMA-IR) (−28.7%, 95%CI, −48 to −10, p = 0.005) without changes in body weight or fat mass. Diet counseling resulted in loss of body weight (1.5%, 95%CI, −2.3 to −0.7, p = 0.001) but no changes in free fatty acids, fasting glucose, or HOMA-IR were found.ConclusionOur results indicate that small weight loss does not produce measurable health benefits, whereas short-term regular aerobic exercise can improve glucose and lipid metabolism even in the absence of weight loss in previously sedentary overweight and obese women.

论社会工程的三个基本属性——以三峡工程为例

作为一门新兴的社会科学交叉学科的社会工程学,当下其必须要做的学术工作中包括对社会工程的性质进行深度的学理分析。对社会工程特质的分析是社会工程理论与方法总体研究中的重要组成部分。社会工程不仅具有社会性、系统性。而且还具有复杂性。正是这三个基本社会属性构成了所有社会工程的行为过程或实践特点。

Gender Disparity in STEM Disciplines: A Study of Faculty Attrition and Turnover Intentions

This study examines the underrepresentation of women faculty in science, technology, engineering, and mathematics (STEM) by comparing the intentions of attrition and turnover between genders in Research and Doctoral universities. It is found that the two genders did not differ in their intentions to depart from academia, but women faculty had a significantly higher likelihood to change positions within academia. The indications are that women and men are equally committed to their academic careers in STEM; nonetheless, women’s stronger turnover intentions are highly correlated with dissatisfaction with research support, advancement opportunities, and free expression of ideas. The findings suggest that the underrepresentation of women is more convincingly explained by an academic culture that provides women fewer opportunities, limited support, and inequity in leadership, rather than by gender-based differences such as roles in family responsibilities. Changes in academic STEM culture are needed in order to attract more women scientists and narrow the current gender gap.     

试论与时俱进的理论品质

与时俱进是马克思主义的内在要求,它蕴含着实践性、革命性、开放性和创新性。马克思主义长盛不衰的根本原因就在于与时俱进,与时俱进是发展马克思主义的必然要求,是马克思主义发展的永恒命题。“三个代表”重要思想是与时俱进的最新成果。     

从苏东剧变看坚持"三个代表"的重要性

“三个代表”重要思想的提出具有重大的理论和政治意义，它解决了任何一个政党都必须面对的三个问题：人民群众生存和发展必需的物质资料、思想建设和人心背向。苏东剧变的社会根源及历史启示就是没有解决好这三个根本问题，因此我们要正确认识和实践“三个代表”重要思想。
