关于山东省第21届运动会青少年武术套路比赛中影响器械抛接动作稳定性的心理分析

在武术套路比赛中,器械的抛接技术是掌握完成整套动作的重要环节和难点,也是比赛能否成功获得好成绩的关键。本文就2006年山东省第21届运动会青少年武术套路比赛中存在的问题以及原因进行了理论和技术分析,进一步讨论了影响器械抛接技术的心理、空间、时间等主要因素以及改进的措施。并结合我国优秀运动员(运动队)的训练经验,提出了加强青少年武术套路抛接器械稳定性的相关建议。     

我国科技基础条件资源配置效率研究

大型科学仪器资源是保障国家科技进步和科技创新的重要物质基础和手段,同时也是国家的重要战略资 源。随着我国对大型科学仪器资源投资越来越大,如何度量各地区的资源的配置效率成为当前国家科技管理部门关注 的重要问题。首先从整体、区域和应用领域介绍我国大型科学仪器资源分布情况,然后通过建立地区大型科学仪器资 源配置效率评价指标体系,并运用DEA方法中的BCC模型对各地区资源配置的效率进行比较。最后根据评价结果提出 相关的政策建议。     

《票据法》第二十七条批评

长期以来,票据一直享有"商业货币"的美誉,可见它在经济领域发挥着重要的功能。1996年1月1日我国《票据法》颁布施行。这部《票据法》规范了我国的经济活动,使我国的票据活动走向了法制化的新阶段。但是这部《票据法》也存在着诸多的问题,究其原因就在于它是中国经济转型期的产物,在它的内部充满了计划与市场角力的矛盾,而这种矛盾在我国市场经济日渐繁荣的今天逐渐显现。其中第二十七条是关于汇票背书的规定,背书转让制度保障了票据的顺利、迅速的流通,真正地实现了票据的制度概念。但是笔者认为本条无论是在内部逻辑上还是在制度构建上都存在这诸多的问题,本文将集中于本条提出批评性的意见希望有利于本法的日后修改。     

Are the Multidimensional Body Self-Relations Questionnaire Scales stable or transient?

Body image is an important concept when assessing mental health and, thus, a target for intervention work. The common approach to assess body image is via self-report and, consequently, it is important to assess stability and susceptibility of items to random change. Participants (N = 99, aged: 18–30 years) completed the 34-item Multidimensional Body Self-Relations Questionnaire-Appearance Scales (MBSRQ-AS) twice, separated by two weeks. Stability was quantified by calculating the test–retest differences for each item, with a stable item showing 90% of respondents’ differences within a criterion of ≤±1. This method was used in preference to correlation, which is a test of association rather than agreement. Analyses identified 29 stable items. Five items were found to be unstable including the entire “Appearance Evaluation” scale. One particular unstable question, Q9 = “Most people would consider me good-looking”, revealed strong associations with both gender and weight status. Forty-four per cent of “overweight” respondents changed their minds by more than ±1 compared with only 10% of “normal-weight” participants, suggesting that being overweight is associated with uncertainty and instability. We suggest that future research is needed to investigate why such factors as being overweight appear to be linked to instability in self-report measures of body image.     

Does e-government reduce the administrative burden of businesses? An assessment of business-to-government systems usage in the Netherlands

The reduction of the administrative burden on businesses is an important governmental policy objective. Electronic government is presented as a promising reduction strategy in many countries. Underlying assumptions and mechanisms are hardly ever made explicit and scientific evidence of successful implementations is scarce. This paper presents an assessment of business-to-government systems in use in the Netherlands. Results show that organizational characteristics are the most influencing factors of perceived burden reduction and implementation effectiveness. Whereas perceived organizational benefits positively relate to the overall confirmation of the former system adoption decision. Surprisingly the quantitative, usage related characteristics do not present any statistical relevance. These findings help us understand existing differences in appreciation between business and governmental representatives on the successfulness of e-government projects in reducing the administrative burden on businesses. Furthermore, research results can help to enhance the effectiveness of e-government policy and measurement instruments.

两类控制方式下创业企业剩余控制权、特定控制权配置机理——以金融工具为载体的创业投资两阶段投资分析

文章分析了创业企业控制权类型、控制权收益构成及其之间的对应关系,通过建立控制权共享收益函数将人力资本专有性与专用性、投资专用性、信任度纳入统一的分析框架。构建了以金融工具为载体的两类控制方式下,两类控制权的两阶段配置模型,分析各因素对不同控制权配置的作用机理,并运用Mathematica软件对理论模型分析结论进行数据模拟。研究发现,受两类控制方式下企业家与投资家控制权收益不同的影响,关键因素对企业剩余控制权配置的作用机理存在显著差异,但对特定控制权配置的影响基本一致。具体表现为,随着创业企业绩效的改善与创新项目成功概率的增加,人力资本专用性、投资专用性、信任度与投资家获得的剩余控制权在联合控制方式下呈先增后减的非线性变化关系,在相机控制方式下呈先减后增的非线性变化关系;人力资本专有性与投资家获得的剩余控制权在联合控制方式下呈先减后增的非线性变化关系,在相机控制方式下呈先增后减的非线性变化关系。
