The satirical value of virtual worlds

Imaginary worlds have been devised by artists and commentators for centuries to focus satirical attention on society’s problems. The increasing sophistication of three‐dimensional graphics software is generating comparable ‘virtual worlds’ for educational usage. Can such worlds play a satirical role suggesting developments in distance education practice and policy? The article examines the emergence of Hinterlife, a cartoon world run by a disarmingly despotic academic known to the real world only by his virtual name, Professor Horace. This article suggests that a healthy dose of satire can help distance education to overcome the problems generated in difficult economic times.

3-min whole body cryotherapy/cryostimulation after training in the evening improves sleep quality in physically active men

Exercise training during evening may disturb sleep patterns and hinder recovery process. The present study aimed to examine the effect of whole body cryotherapy (WBC) exposure after training in the evening on sleep quality and night heart rate variability (HRV). A total of 22 physically active men were randomized to undergo either WBC (3-min at ?40°C, wind speed of 2.3?m?s^?1) or passive recovery (control) following an evening training consisting of 25?min of continuous running at 65% of the maximal aerobic speed (MAS) followed by intermittent running at 85% of the MAS. Each night following the training, the number of movements and HRV during sleeping time were recorded. The next morning, subjective sleep quality and perceived pain were assessed using Spiegel questionnaire and a visual analogue scale, respectively. The number of movements during the night following WBC was significantly reduced (p?p?p?p?p?相似文献

薪酬差距与公平差别阈差异对员工心理和行为的影响——基于员工"分配公平感""任务绩效"和"偏离行为"的实证检验

以成都、重庆和昆明三地企业的581个员工为样本,分为薪酬差距与员工公平差别阈有差异组和无差异组,分析薪酬差距与公平差别阈差异对员工分配公平感、任务绩效及偏离行为的影响,结果表明:无差异组中的员工分配公平感和任务绩效显著大于有差异组,而员工偏离行为显著少于有差异组;在普通员工与基层管理者、与中层管理者、与一般高层管理者、与公司"一把手"4类比较中,无差异组与有差异组的员工分配公平感存在显著差异;在同类岗位普通员工之间和普通员工与公司"一把手"2类比较中,无差异组与有差异组的员工任务绩效存在显著差异;在同类岗位普通员工之间、普通员工与基层管理者、与一般高层管理者、与公司"一把手"4类比较中,无差异组与有差异组的员工偏离行为存在显著差异.企业应科学测定不同层级员工所认同的公平差别阈,进而设计合理的薪酬差距.     

The identification of able socially deprived pupils: LEA advice to primary schools

This article examines the advice that local education authorities (LEAs) in England and Wales give to primary schools on the identification of able socially deprived pupils. The research described here is situated within the context of the theoretical literature and central government policy regarding these children. It is noted that identification of able pupils has become more inclusive, although limited research has been undertaken on socially deprived able pupils. The role of central government in supporting these pupils through flagship initiatives such as Excellence in Cities is then analysed and the identification advice that LEAs provide to primary schools is examined. It was found that, whilst LEAs provide systematic and inclusive identification advice, the identification of able socially deprived pupils is only tangentially addressed. The problems associated with the use of checklists by LEAs are examined and the implications of the research are discussed.     

大学生体育社团对大学生睡眠方式的影响相关性研究与分析——对江苏省高校大学生生活方式调查与研究之二

通过文献资料法、问卷调查法,对大学生体育社团对大学生睡眠方式的影响相关性进行了分析,结果表明大学生体育社团与大学生睡眠方式相关性如下:(1)在每天睡眠时间的比较上,参与体育社团组与非参与体育社团组没有显著性差异。(2)参与体育社团有利于减轻大学生的压力、克服内向的人格特征;可以较好减低焦虑和抑郁等不良心理;获得的社会支持多于非参与体育社团组大学生;在遇到压力时,会采取主动的应对方式;锻炼方式提升睡眠质量。因此参与体育社团组的大学生睡眠质量要好于非参与体育社团组的大学生。     

基于相对剥夺理论的救灾物资运输车辆分配公平性

在救灾物资运输车辆分配问题上,重点关注车辆分配对灾区灾民心理的影响.基于相对剥夺模型对配送车辆进行分配,利用横向和纵向相对剥夺感评价车辆分配的公平性.首先,利用横向相对剥夺感评价不同种类物资运输车辆的分配公平性,分析救灾物资运输车辆分配失衡的原因;然后利用纵向相对剥夺感评价不同受灾地区车辆分配的公平性,得到均衡分配车辆的方法,使救灾物资的配送更加符合灾民需求.该方法可为决策者提供救灾物资运输车辆分配的依据,也可增强救灾物资配送的公平性.     

瑜伽对女大学生身体素质、睡眠质量和焦虑的影响

通过文献资料法、问卷调查法、实验法和数理统计法,研究16周瑜伽练习（1次／周,90min／次）对女大学生身体素质、睡眠质量和状态焦虑的影响。结果显示：低频次的瑜伽练习可有效改善女大学生身体素质;低频次的瑜伽练习对女大学生睡眠质量和状态焦虑无显著性影响;学生课外体育锻炼情况与睡眠质量呈显著性相关,与状态焦虑无显著性相关。     

运动改善睡眠障碍的实验研究

通过对比,观察运动对睡眠障碍的改善情况。将58名经匹兹堡睡眠质量评价确定有睡眠障碍的高校女生随机分为2组,一组每周三次进行运动训练,每次运动量要求达到8O%的靶心率。另一组不进行运动训练作为对照组。4个月后用匹兹堡睡眠质量指数(PSQI)进行评价。结果运动组较对照组睡眠质量有明显改善(P<0.05);同时心理状态和身体素质也比实验前有所好转,与对照组相比有明显的差异。每天按运动处方进行一定运动量的锻练可以明显改善睡眠质量,其原因可能源于心理和体质的改善。
