借助EMG值对优秀女子手枪运动员实施表象技能基础训练的初步研究

对两名优秀女子手枪运动员借助 EMG 进行表象技能基础训练进行了详细的描述。从 EMG 及其他结果上初步得到如下结论:1.表象技能基础训练按照心理教育、放松练习、表象练习三个阶段进行;2.用 EMG 反馈、表象脚本、对表象内容陈述、实际做动作与表象相结合、布置家庭作业等方法,可以使运动员尽快地在表象中出现心理生理反应;3.EMG 值的高低及规律性变化与表象的清晰性有密切的关系。

提高投篮命中率训练方案的优化与研究

通过查阅文献资料，专家咨询与长期实践，收集了大量提高投篮命中率的训练方法，经运用体育统计理论分析处理，优化出4种训练方法，在普通高校运动队的训练中进行对比实验。实验证明，用优化出的训练方法训练，更有效的提高了运动员投篮命中率。     

远距离单手肩上投篮训练方法探讨

讨论影响投篮命中率有7个因素:手法、瞄准的方向、球的旋转、抛物线、协调性、判断反应和心理因素,并提出提高远距离投篮命中率的训练方法.     

中距离不同投篮点投篮命中率的差异分析

通过对两个不同水平的班级的投篮命中率的测试和检验。发现中距离不同投篮点的投篮命中率不存在显著性差异,投篮的“习惯位置”只是心理的产物,它并不意味着“非习惯位置”的投篮低命中率。但比赛中的“习惯位置”有待于进一步探讨。

Ecological Study of Graduation Rates and GPA in a Library Credit Course

The purpose of this ecological study was to examine the impact of a library credit course on graduation rates and GPA using pre-existing records. Over 20?years of aggregate institutional data were analyzed to evaluate the course's impact on first-time-full-time, white, and black students. Results were mixed: students who took the course were less likely to graduate than their peers who did not take the course but enjoyed slightly higher GPAs at graduation. It was discovered that students taking the course are not representative of the overall student body and struggle academically. Implications for revisions to the library credit course are discussed.     

Can a non-Muslim Mass Shooter be a “Terrorist”?: A Comparative Content Analysis of the Las Vegas and Orlando Shootings

ABSTRACT

This study used the 2017 Las Vegas and 2016 Orlando mass shootings as case studies to explore alleged double standards in reporting of events featuring Muslim and non-Muslim mass perpetrators of violence. The study used framing theory and content analysis to examine Los Angeles Times and New York Times coverage of the shootings during the one week immediately following each event. Findings are consistent with previous literature and the researchers’ expectations. The Orlando shooting, carried out by a Muslim, was allotted more coverage despite the fact that it produced nine fewer fatalities than the Las Vegas shooting, perpetrated by a white non-Muslim. The analysis also showed that the examined newspapers were more likely to employ a “terrorism” frame in their coverage of the Orlando shooting than in their coverage of the Las Vegas shooting; link the Orlando mass shooting with the global war on terrorism; and to humanize Stephen Paddock, the white perpetrator of the Las Vegas shooting. Framing differences found in this study may contribute to downplaying the threat of white male gun violence, and to reinforcing fears of Islam and Muslims.     

小学四年级学生对平均数概念理解的发展过程

利用Pirie和Kieren提出的数学理解发展模型,分析了3名小学四年级学生对平均数概念理解的发展过程.结果表明:学生对平均数概念的理解经历了初步了解、产生表象、形成表象、关注性质和形式化等5个水平.在理解发展过程中,当学生发现他的思想和行动与自己所面临的问题不一致时,他就要折返回内层水平来扩展自己目前的活动能力和活动空间.而教师的干预则激发了学生的折返,为学生提供了独立建构或修正个人表象的机会.
