Campus Walkability,Pedometer-Determined Steps,and Moderate-to-Vigorous Physical Activity: A Comparison of 2 University Campuses

Objective and Participants: At 2 Arizona State University (ASU) campuses, the authors measured student activity and distance walked on campus, as well as student-reported walkability around the student union. Methods: Students from ASU-Polytechnic (n = 20, 33% male) and ASU-Tempe (n = 20, 60% male) recorded distance walked on campus and wore physical activity monitors for 5 days. Results: Polytechnic students spent an average of 36.9 minutes in moderate-to-vigorous physical activity each week; Tempe students spent 69.5 minutes (p < .001). At Polytechnic, students walked an average of 7,674 steps per weekday; at Tempe, 11,294 steps (p = .003). Female students at Polytechnic walked an average of 1.3 km/d; at Tempe, 4.3 km/d (p < .001). At Polytechnic, men walked an average of 1.4 km/d; at Tempe, 3.1 km/d (p = .03). Tempe students rated campus walk-ability as very good, whereas Polytechnic students rated it fair (p < .001). Conclusions: Students at both campuses met activity recommendations; noted differences may be attributed to the built environment's contribution to walkability.     

学生体育效果目标评价方法的研究

长期以来 ,体育效果的评价没有考虑学生生长发育的非同步性及身体素质的个体差异 ,不利于对学生进行个性教育。目标评价引入了目标完成等级的指标 ,既能够描述学生体育能力的个体水平 ,又能够准确体现体育学习过程的前后变化 ,是一种相对合理的体育效果评定方法。目标评价方法对促进教学目标向学习目标转化 ,终结性评价向过程性评价转化 ,实施个性教育 ,推进素质教育的开展 ,有着深远的意义。     

浅析笛卡尔的二元论和西方近代哲学中的身心关系问题

心身问题或心物问题(mind-body problem),是关于心理的东西(the mental)的本体论地位,本质以及与身体的相互关系的问题。在西方认识史上,先哲们对这个问题分别给予了缜密思考后的回答。本文首先回到西方近代心灵哲学上一个颇有影响的心灵观,从笛卡尔的实体二元论说起,分析其内在逻辑矛盾产生的根源和面临的困境,再集中探讨与笛卡尔同时代的哲学家们对其观点的改进或改造,并逐一做出梳理和短评。     

自然伽马能谱测井谱解析方法研究

自然伽马能谱测井是重要的核测井方法之一，其地面信息处理系统的关键是实测谱解析技术。低分辨率是自然伽马能谱测井仪的固有弱点，且测井过程中信噪比较低，造成测井置信度不高。从自然伽马能谱测井原理出发，通过中海油实验数据处理后获得的放射性核素的标准计数率谱，对自然伽马能谱测井4种传统数据处理方法的优劣进行了对比，初步探讨了将灵敏度高、空间分辨率好的直接解调方法移植到自然伽马能谱测井谱解析中，为自然伽马能谱测井谱解析方法的选择提供了依据。     

Top Ten Challenges for Understanding Gender and Aggression in Children: Why Can’t We All Just Get Along?

This essay identifies ten significant methodological challenges for understanding aggression and gender. In light of the recent explosion of research on indirect/relational/social aggression, it seems important to clarify gaps in our current understanding and to identify promising methods by which better answers might be found. The discussion begins with basic issues of definitions, contexts and subtypes, moves on to points concerning sampling and measures, and addresses whether current evidence warrants deciding that girls are as aggressive as boys. We conclude that although research has shown that the majority of girls' aggression takes indirect/relational/social forms, it is premature to conclude that boys do not also engage in these behaviors. We caution against assuming that physical and indirect/relational/social aggression are comparable in their developmental origins and consequences, and urge researchers to consider that fully understanding indirect/relational/social aggression might require different conceptual frameworks and research methods.

试论高校体育教学伤害事故的司法责任认定及解决机制*

在当下有关法律法规不甚健全的情况下，为了尽可能地避免相关的体育教学伤害事故的发生，以及可能会出现的法律风险，国家有责任和义务建立一整套完备的高校体育教学伤害事故赔偿法。通过法律的约束，使学校包括学生在内的责任人，自觉实现真正意义上的知法、懂法、守法，杜绝伤害事故的发生。     

Prevalence of Sufficient Physical Activity Among Parents Attending a University

Objective: The benefits of regular physical activity are well documented. However, approximately half of all university students are insufficiently active, and no research to date exists on the activity behavior of university students who are also parents. Participants and Methods: Using an adapted version of the Godin Leisure Time Exercise Questionnaire (ie, the Physical Activity Prevalence Questionnaire), the authors examined the prevalence of sufficient physical activity among 245 parent students from 6 faculties and 12 programs. Results: Half (49.5%) of the students who were not parents (n = 90) were sufficiently physically active, compared with 16% of students who were parents (n = 3, p < .002). The authors found that 33.3% of parents and 13% of nonparents limited their activity level as a result of illness or injury (p < .05). Conclusions: Most parent students in this study were insufficiently active and at potential risk for the negative health consequences of inactivity. This is a grossly understudied population, and researchers must conduct further studies to understand what can be done to facilitate physical activity among this potentially vulnerable group of students.
