青少年骨发育X线分级方法

目的 利用青少年骨关节x线影像变化规律制定青少年骨发育X线分级标准.方法 参照国内外权威学者关于不同部位关节骨骼发育分级的研究成果,以骺软骨发育组织学分层(区)为理论支撑、以骨发育X线影像特征为基础的分级原理.横向和纵向观察我国河南、海南、浙江三个省份300名11～20周岁男、女性青少年双侧锁骨胸骨端及左侧肩、肘、腕、髋、膝、踝关节骨发育X线影像特征,选取与年龄变化关系密切的24项骨骼发育指标.结果 根据不同部位关节骨骺生长变化规律,将24项骨骼发育指标分为2级至8级不等.研究显示,各单一关节组成诸骨发育指标的分级基本相同或接近.单一关节内不同的骨骺发育变化具有同步性.结论 本分级标准涉及骨骼发育指标广、适用年龄范围宽、可操作性强,为我国法医学活体骨骼年龄推断建立了良好的基础平台.     

基层警察的行动性质、逻辑分析及管理路径

基层警察位于公安组织架构最底层,在一线或现场,直接与群众打交道。他们执行上级的决策,同时又有自己选择和决策过程,拥有自由裁量权,现场工作场景中处于信息有利方,而且与群众之间也存在着不对称的权力关系。其所处的特殊行政生态使得他们表现出以庸碌无为追求“闲暇效用最大化”、在规则依赖中寻求责任免除、在利害权衡中选择行为等典型的行动逻辑。故此,对于基层警察的管理应通过公安信息化建设促进基层警务规范化、通过法律责任控制加大对基层警察的监督、通过警务社会化实现对基层警务工作的政治控制、用提高职业道德来实现基层警察的自我控制。     

Work redesign in development perspective: An empirical study of multitasking among civil servants in Malawi

Civil servants in many developing countries are increasingly faced with multitask situations at work to improve the efficiency of public sectors. Although multitasking might boost employee productivity, its potentially negative impact on other areas of employees’ lives has been ignored. Drawing upon the conservation of resources theory, our research aims to investigate whether, how, and when multitasking at work decreases the subjective well-being of employees in the public sector. Using a two-wave survey of 164 civil servants in Malawi, our findings showed that multitasking at work was positively related to employees’ negative affect and negatively related to their satisfaction with life and positive affect through emotional exhaustion. Moreover, the study found that polychronicity, which refers to one's preference to handle more than one task at the same time, moderated the relationship between multitasking and emotional exhaustion, such that the association described above was weaker when an employee's polychronicity was higher. Finally, the indirect impact of multitasking on positive affect through emotional exhaustion was also moderated by polychronicity. These findings provide some theoretical and managerial implications for public sector in developing countries on how to focus on employee well-being while using multitasking work design.

Using equations from power indices to analyze figure skating teams

Power indices were originally developed to measure voting power. However, Saari and Sieberg (Games Econ Behav 36:241–263, 2001) and Saari (Chaotic elections, American Mathematical Society, Providence, 2001a) have suggested that the equations from power indices could potentially be used in some sports contexts as a way of evaluating athletes. This article explores this idea in the context of figure skating. The International Skating Union developed team events in figure skating for the 2014 Winter Olympic Games in Sochi, Russia and for other major competitions. In this article, we show how the Shapley–Shubik and Banzhaf indices can be used to analyze contributions of athletes to their countries’ teams in figure skating team events. We illustrate this approach by analyzing the results from the 2014 Winter Olympic Games figure skating team event. We also discuss some ways in which the numbers assigned by the equations from power indices can be used in the figure skating context.

新中国偷税罪的立法沿革

建国三十年,国家几乎不征税,也就用不着规定偷税犯罪。“79刑法”中关于偷税罪的规定,也只是宽泛、粗略的规定。1986年最高人民检察院的《立案标准》解决了偷税罪在司法实践中的操作性问题。1992年3月的《两高解释》明确了偷税罪的主体,明确了偷税罪的五种偷税手段,明确了偷税罪的起点标准;1992年9月的《税收征管法》和《补充规定》标志着中国税收征管工作走向法制化。“97新刑法”则使偷税罪的立法渐趋完善,而2002年的《高法解释》则解决了司法实践中对于偷税罪刑法适用的诸多问题。     

建立科学的激励机制促进高校辅导员队伍建设

加强高校辅导员队伍建设有着重大而深远的意义。通过现代激励理论可以看出,长期的高工作投入和低工作回报,往往会降低辅导员职业地位,难以吸引优秀人才,也会降低他们的工作积极性,影响思想政治教育效果。为加强辅导员队伍建设,高校应以提高辅导员的全面薪酬、提升其心理满足程度为着眼点,建立科学的激励机制。
