关于1954年宪法

近代中国是一个民族民主革命风云激荡的时代。作为中国革命的历史成果,1954年宪法是对近代中国宪法问题和宪政运动历史经验的总结,体现了对未来社会主义政治建设的发展思路,也是中国当代民主法制建设的良好开端。它标志着近代以来的中国宪法和宪政理论发生了重大转折,即以人民民主专政理论为指导的当代宪法代替了在中国未能成长起来的西方移植性宪法。同时,1954年宪法在经济制度和政治基础两个方面所具有的过渡性特点也预示了这部宪法本身的不稳定性,昭示着中国的民主法制建设是一个长期而艰巨的任务。

Hip and upper extremity kinematics in youth baseball pitchers

The purpose of this study was to examine the relationship between dynamic hip rotational range of motion and upper extremity kinematics during baseball pitching. Thirty-one youth baseball pitchers (10.87 ± 0.92 years; 150.03 ± 5.48 cm; 44.83 ± 8.04 kg) participated. A strong correlation was found between stance hip rotation and scapular upward rotation at maximum shoulder external rotation (r = 0.531, P = 0.002) and at ball release (r = 0.536, P = 0.002). No statistically significant correlations were found between dynamic hip rotational range of motion and passive hip range of motion. Hip range of motion deficits can constrain pelvis rotation and limit energy generation in the lower extremities. Shoulder pathomechanics can then develop as greater responsibility is placed on the shoulder to generate the energy lost from the proximal segments, increasing risk of upper extremity injury. Additionally, it appears that passive seated measurements of hip range of motion may not accurately reflect the dynamic range of motion of the hips through the progression of the pitch cycle.     

Timescales for exploratory tactical behaviour in football small-sided games

The aim of this study was to identify the dynamics of tactical behaviour emerging on different timescales in football small-sided games and to quantify short- and long-term exploratory behaviour according to the number of opponents. Two teams of four professional male footballers played small-sided games against two different teams with a variable number of opponents (3, 5 and 7). Data were collected using a combination of systematic observation and a non-differential global positioning system (15 Hz). The temporal diversity and structural flexibility of the players were determined by calculating the dynamic overlap order parameter q, entropy and trapping strength. Analysis of the exploratory dynamics revealed two different timescales, forming a different metastable landscape of action for each constraint. Fast dynamics lasted on average a few seconds and consisted of changes in tactical patterns. The long timescale corresponded to the shared tasks of offence and defence lasting tens of seconds. The players’ tactical diversity decreased with an increasing number of opponents, especially in defence. Manipulating numerical imbalance is likely to promote changes in the diversity, unpredictability and flexibility of tactical solutions. The fact that the temporally nested structure of constraints shaped the emergence of tactical behaviour provides a new rationale for practice task design. The manipulation of numerical imbalance on the timescale of a few tens of seconds, on which the exploratory behaviour of players saturates, may help coaches to optimise the exploratory efficiency of the small-sided games.

服务流程管理视域下公共体育服务流程理论研究

自20世纪90年代以来,"服务流程管理"理论逐渐受到服务组织的重视,并开始应用于各种服务行业。在基本公共服务越来越受到重视的社会背景下,服务流程管理理论逐渐应用于公共服务之中,而公共体育服务作为公共服务的重要组成部分,服务流程管理理论仍未得到应用。国务院相继颁发了《全民健身条例》(2009)和《全民健身计划(2011-2015年)》(2011),都为公共体育服务的发展提供了保障。通过文献资料法对国内外服务管理理论进行分析,并对公共体育服务理论研究现状进行视域分析,旨在构建我国公共体育服务流程管理理论。     

用流程管理解决图书编校质量的不确定性

提出图书编校质量的不确定性概念,分析产生不确定性的原因,探讨基于流程管理的解决方案。基于“建立流程—明确任务—监督检查—评价激励”的思路,建立编校流程管理链条,即制定合理的编校流程制度,明确各流程任务,引入过程监督和检查措施,设立结果与过程相结合的评价激励机制。通过编校流程管理,降低图书编校质量的不确定性,达到控制图书编校质量的目的。
