从第三种力量到北大西洋联盟——战后初期英国均势政策的变化

战后初期，英国外交经历了从寻求建立第三种力量，企图与美苏平起平坐，到推动建立北大西洋联盟，拉住美国保卫欧洲和英国的安全的变化过程。这一转变受英国国力衰弱、美国的欧洲政策、冷战的爆发的影响。     

The kinematic differences between off-spin and leg-spin bowling in cricket

Spin bowling is generally coached using a standard technical framework, but this practice has not been based upon a comparative biomechanical analysis of leg-spin and off-spin bowling. This study analysed the three-dimensional (3D) kinematics of 23 off-spin and 20 leg-spin bowlers using a Cortex motion analysis system to identify how aspects of the respective techniques differed. A multivariate ANOVA found that certain data tended to validate some of the stated differences in the coaching literature. Off-spin bowlers had a significantly shorter stride length (p = 0.006) and spin rate (p = 0.001), but a greater release height than leg-spinners (p = 0.007). In addition, a number of other kinematic differences were identified that were not previously documented in coaching literature. These included a larger rear knee flexion (p = 0.007), faster approach speed (p < 0.001), and flexing elbow action during the arm acceleration compared with an extension action used by most of the off-spin bowlers. Off-spin and leg-spin bowlers also deviated from the standard coaching model for the shoulder alignment, front knee angle at release, and forearm mechanics. This study suggests that off-spin and leg-spin are distinct bowling techniques, supporting the development of two different coaching models in spin bowling.     

试论民族团结对多民族国家的重要性——以晚清甘肃回民起义的影响为例

清末同治年间爆发的甘肃回民起义延续十几年,甚至光绪年间还余波不断。起义不但给回汉人民带来了生命和财产方面的巨大损失,而且对整个甘肃社会的经济发展、民族团结、文化发展,乃至统一多民族国家的稳定与发展都产生了不利影响。历史经验证明,只有维护民族团结、保持社会稳定,才能促进像甘肃这样多民族聚居区的经济发展和社会进步,给人民营造出安康幸福的生活。

我国区际产业转移研究综述

区际产业转移是发达区域产业结构调整升级的重要途径,是欠发达区域经济崛起发展的良好契机,也是区域产业结构优势转换升级的有效方式。本文从区际产业转移的概念、转移动力、转移战略和路径以及转移效应等四个方面对我国区际产业转移研究进行了综述。总体上,我国区际产业转移的概念研究趋于成熟,在区域产业转移的动力机理机制、准入门槛,产业转移与产业集聚,区域发展战略,地区生态环境等方面均有较多的研究。未来有关产业转移的研究可将触角伸入企业或消费者群等微观层面,以及产业转移与区域创新体系建设的联动效应等中观层次。

江汉政权的领导范围考

江汉政权是清代咸同年间号军起义建立的农民政权,它的根据地虽在贵州思南,但其所领导的范围及影响力却广达黔、湘、川、鄂、赣的号军起义和白莲教支派。本文在掌握翔实史料基础上,从该政权的领导人、传教区域、战略部署、朝廷官员的相关奏折等方面论述了其领导的范围。     

谈职教生自主学习能力的培养

当前讨论职业教育问题时，往往将关注重点放在国家相关政策的完善和对社会各界支持的呼吁上，而对职教生自身能力的培养却没有引起足够的重视。文章立足于职教生自身，从影响机制、影响因素和影响策略几个方面来研究培养自主学习能力对职教生自身发展的优越性和重要意义。
