生态脆弱区社会经济与资源环境耦合协调度研究:以云南省昭通市为例

对于生态脆弱地区,探寻其社会经济发展与资源环境的协调发展模式对于实现地区的可持续发展具有重要意义。构建相对资源承载力模型和耦合协调度模型,测算云南省昭通市相对资源人口承载力和经济承载力,并对"经济-资源环境-社会"系统协调发展度进行时空分析。结果表明：1）昭通市相对资源人口承载力超载严重,社会资源承载力低且显著超载;2）相对资源经济承载力处于富余状态,资源的经济价值尚未充分开发;3）昭通市社会经济发展受资源环境制约显著,系统不协调度有拉大趋势。提高第二产业发展水平,优化产业结构是促进昭通市"经济-资源环境-社会"系统协调发展的主要措施。     

Effectiveness of physical education to promote motor competence in primary school children

Background: Motor skill (MS) competence is an important contributing factor for healthy development.

Purpose: The goal was to test the effectiveness of primary school physical education (PE) on MS and physical fitness (PF) development.

Methods: Three classes (n?=?60, aged 9.0?±?0.9) were randomly assigned to three diverse conditions during a school year: two PE lessons/week (PE-2), three PE lessons/week (PE-3), and no PE lessons control group (CG). BMI, skinfolds, PF (9-min run/walk, sit-up, modified pull-ups), gymnastics, soccer, handball, basketball and track-and-field skills were evaluated. Effect sizes (d) were reported as magnitude of change.

Results: Skinfolds significantly increased only in CG (d?=?1.21). PF composite z-scores improved in PE-3 (d?=?0.61), but decreased in PE-2 (d?=?0.57), and had no changes in CG. Statistically significant improvement was verified in gymnastics and handball skills in both experimental groups (gymnastic: d?=?2.95 and d?=?2.61 for PE-3 and PE-2, respectively; handball: d?=?1.87 and d?=?0.57 for PE-3 and PE-2, respectively), and no changes were seen in CG. In soccer, there were improvements only in the PE-3 (d?=?0.55), and in basketball only in PE-2 (d?=?0.46). There were no changes in any group for track-and-field skills.

Conclusions: PE programs can effectively promote PF and MS development.

我国体育产业发展中公益与商业投资关系研究

我国体育产业从公益事业向产业化发展的过程中，始终面临着一个问题，那就是其中多大成分是公益，多大成分是商业，这个问题也导出了国家在体育公益事业上的投资与产业商业投资之间的合作、冲突和矛盾如何处理的问题。其实体育产业中的公益投资与商业投资具有相互促进、相互补充的关系，政府与企业之间可以相互融资，或者通过政府采购服务的方式，保证两种投资关系的合理和效益最大化。     

审视国家助学贷款政策

随着高等教育的发展,高校贫困生问题日益突出,高等教育的资金需求越来越大,国家助学贷款政策应运而生.理论上,国家助学贷款政策是政府为了促进教育事业的发展、为了高等教育的公平、为了社会的公正而做出的实践性决策,对个人和组织的行为产生影响;其本质是学生、高校、社会之间的利益协调和平衡.就实践而言,学生、学校、政府、银行四方都不同程度地成为国家助学贷款政策的受益者.国家助学贷款工作的健康发展,既需学生、学校、银行和政府的单方努力也需要多方配合.     

久期技术与基于隐含期权的商业银行利率风险管理

从衡量利率风险的久期与凸度技术出发,重点探讨了基于隐含期权及期权调整利差的有效久期和有效凸度模型,并研究了其在我国商业银行利率风险管理中的具体应用。     

人际关系对组织内部知识共享行为的影响研究

以组织内知识共享为研究对象,借鉴经济学中公共物品理论,将组织内知识共享作为一种特殊的公共物品贡献行为,提出对个人利益的考虑将阻碍知识共享而个人功效感能够促进知识共享,进而提出团队工作以及信任度将通过对个人利益和个人功效感的作用影响知识共享行为.问卷调查的结果验证了理论研究的有效性.     

University Programme Preferences of High School Science Students in Singapore and Reasons that Matter in their Preferences: A Rasch analysis

This study explored an under-researched area in science education—the university programmes preferred by high school students who take physical science subjects and the reasons that matter in their preferences. A total of 1,071 upper secondary and pre-university students in Singapore, who take physical science subjects among their range of subjects, participated in this study. A survey method was adopted and the Rasch model was used to analyse the data. Overall, Business Studies was ranked as the predominant choice; nonetheless, scientific programmes such as Science, Engineering, and Mathematics are generally still well liked by the students. When gender differences were examined, we found that students largely followed gender-typical programme preferences, in which males tend to incline towards Engineering while females tend to incline towards Arts and Social Sciences. Students prefer a university programme based on their individual interest and ability, with career aspiration and remuneration coming next. Interestingly, females place greater emphasis on career aspiration than males. Some implications of the study are discussed.
