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.     

Perceived health problems in swimmers according to the chemical treatment of water in swimming pools

The objective of this study was to determine which chemical treatment used for disinfecting water in indoor swimming pools had the least impact on users' perceptions of health problems, and which generated the greatest satisfaction with the quality of the water. A survey on satisfaction and perceived health problems was given to 1001 users at 20 indoor swimming pools which used different water treatment methods [chlorine, bromine, ozone, ultraviolet lamps (UV) and salt electrolysis]. The findings suggest that there is a greater probability of perceived health problems, such as eye and skin irritation, respiratory problems and skin dryness, in swimming pools treated with chlorine than in swimming pools using other chemical treatment methods. Pools treated with bromine have similar, although slightly better, results. Other factors, such as age, gender, time of day of use (morning and afternoon) and type of user (competitive and recreational), can also affect the probability of suffering health problems. For all of the above, using combined treatment methods as ozone and UV, or salt electrolysis produces a lower probability of perceived health problems and greater satisfaction.

论中华苏维埃共和国检察机构的设置及其职能

中华苏维埃共和国时期 ,设立了以工农检察部为主体 ,包括军事检察所、政治保卫局检察科、审判机关内设检察人员在内的苏维埃检察机构 ,设置了检察机关管辖和指导的突击队、轻骑队、工农通讯员等群众性组织。具有检举权、调查权、建议权、公诉权、抗诉权和检察权等职能 ,初步形成了富有中央苏区特色的检察制度。这套以党和政府的专门检察机构为主体 ,专门工作与群众监督相结合 ,检审分立与审检合一相结合的检察制度的建立和实施 ,对中央革命根据地的巩固和发展起了重要的作用 ,是中华人民共和国检察制度产生和发展的渊源     

案例教学法的本质特征及其适用性分析

本文认为案例教学法是一种由培训者控制、受训者作为主体参与、围绕真实案情展开的特殊教学方法,有别于以教师为中心的传统教学方法;具有过程的开放性、信息的对称性、思维的多元性与创新性等特征,其过程的意义往往大于结果。案例教学法在培养学习者分析和处理实际问题的能力、处理复杂事件的应变能力以及团队精神等方面表现出良好的适用性。
