Do Test Scores Buy Happiness?

Since at least the enactment of No Child Left Behind in 2002, standardized test scores have served as the primary measures of public school effectiveness. Yet, such scores fail to measure the ultimate goal of education: maximizing happiness. This exploratory analysis assesses nation level associations between test scores and happiness, controlling for a strong correlate of both, per-capita Gross Domestic Product (GDP). Controlling for GDP, the association between test scores and happiness is greatly decreased, offering reason to question the sole use of test scores as measures of school success.

游戏平台入侵检测技术研究

网络安全问题是一个十分复杂的问题,涉及到电子商务、信息交换和游戏服务器。入侵检测与防御技术作为新一代网络信息安全保障技术,它主动地对网络信息系统中的恶意入侵行为进行识别和响应,不仅检测和防御来自外部网络的入侵行为,同时监视和防止内部用户未授权活动和误操作行为。本文提出了针对游戏服务器的入侵检测方案,在一定程度上缓解了黑客攻击游戏服务器的行为。     

基于RTL行为模型的测试产生及时延测试方法(英)

寄存器传输级(RTL)测试产生及时延测试是当今集成电路(IC)测试技术中亟待解决的问题和研究的热点.首先从IC逻辑测试的测试产生和IC时延测试方法这两个方面系统地综述了测试产生和时延测试领域迄今为止的主要研究成果.在RTL行为描述的测试产生方面,提出了新的RTL行为模型的描述方法:行为阶段聚类描述,并提出了基于聚类的测试产生技术.将这些技术集成到RTL级ATPG系统ATCLUB中,在提高测试产生效率及缩短测试长度方面效果显著.在IC时延测试方面,提出了一种新的可变双观测点的时延测试方法。基于该方法提出了新的时延故障诊断方法,实现和完善了可变双观测点的时延测试系统DTwDO.DTwDO提供了从时延测试到故障诊断等一系列测试工具,有效减少了测试通路数,提高了故障覆盖率,并有很高的故障定位成功率.     

农村纠纷调解中的村治逻辑——对浙东先锋村的政治人类学考察

农村纠纷调解机制嵌入在乡村治理实践的结构性变迁之中,并随着乡村治理逻辑的演变而发生相应变化。对浙东先锋村纠纷调解实践变迁的政治人类学考察表明,20世纪90年代中后期以来,受日益彰显的乡村治理性危机的影响,农村基层组织逐步开始更多地使用策略性调解手段,放弃了对地方性文化共识中纠纷调解规范的严格遵守,而且纠纷调解越来越重视暂时性＂息讼＂协议的达成,其实践呈现出越来越复杂的发展态势。后税费时代,富人当政之后的农村纠纷调解仍然存在类似的问题,治理权力严重受限的农村基层组织不得不采取以现代法律为内在基准,以面子、人情和金钱等可控资源为策略性调解手段的办法来解决村民纠纷。而农村纠纷调解的依附性对当前农村基层组织的发展提出了重要挑战。

基于四级考试成绩对民办理工科学生外语学习状况的调查

语言测试不仅可以考察学生的语言能力,而且可以反映教学工作的长处和不足.基于此,对民办理工科学生的英语四级成绩进行分析,描述了这部分学生的外语学习不太令人满意的状况,从而得出结论和启示:民办学生、尤其是理工科学生的外语教学应该作出调整和变化.     

The virtual anatomy laboratory: usability testing to improve an online learning resource for anatomy education

An increasing number of instructors are seeking to provide students with online anatomy resources. Many researchers have attempted to identify associations between resource use and student learning but few studies discuss the importance of usability testing in resource design and modification. Usability testing provides information about ease of use and resource flexibility and indicates navigational issues that contribute to extraneous cognitive load for the user. An example of usability testing for modification of an online anatomy resource called the "Virtual Lab" is presented. Usability testing was used to determine whether increased content would impair navigation through the interface. Subjects with varying levels of experience with anatomy content were recruited to assess efficiency and effectiveness (defined by usability standards) of the original resource and of the redesigned resource. Comparisons between usability evaluation of the original "Virtual Lab" (OVL) and of the redesigned "Virtual Lab" (RVL) revealed that subjects were better able to successfully complete tasks using the RVL than they were with the OVL. Results also demonstrated that subjects did not take significantly more time to successfully complete tasks with the RVL. Additionally, usability testing revealed that subjects were able to successfully complete tasks using the RVL regardless of whether they possessed prior experience with anatomy content or not. Results of this study suggest that the modified resource is more effective for users. The example presented here underscores the need for usability testing prior to resource implementation and whenever significant changes are made to a resource interface.     

体育概念研究进展

认为研究体育概念的适宜方式是连续撰写论文。作者于1989年写出其第一篇专题论文,认为体育的属性是人的肢体活动,其种差是强化体能和非生产性。该专题研究持续了20多年,现已构织出体育概念四级对接体系。     

冥想念动训练对肌肉力量增长的实验研究

目的:本研究应用冥想念动训练方法来提高运动员对肌群的协同控制能力,有效提高其完成运动动作时的力量。方法:16名受试者随机分成A、B两组。均进行负重屈肘练习,重量12RM,重复10次,每天3组,每组负重训练完成后,A组放松休息,B组平卧进行冥想念动训练,共训练30 d。采用美国产MERAC等速测力系统测试训练前后肱二头肌在各种收缩状态下的Peak Speed或Peak Torque来评价受试者的肌肉力量。结果:训练后,冥想念动训练的B组的等张收缩力量、等动收缩力量均要优于只进行常规训练的A组。而两组间等长收缩力量无统计学意义的差异。这可能是由于冥想念动训练方法有效地在受训者神经系统中固化了动作过程中撷抗肌的拉长或放松模式,从而明显地增加了受训者完成运动动作时原动肌与撷抗肌的合力的结果。
