普通高校健美操教学内容体系的"主题单元"构建

通过采用文献资料、面访、问卷调查、数理统计及实证研究等方法,依据具体化的教学目标,以"主题单元"取代"知识逻辑体系"构建普通高校健美操课"6单元64学时"的内容体系,并进行教学实验与分析.旨在有效完成健美操教学目标,丰富健美操教学理论,深化体育课程与教学的改革.     

论刑法定量因素的设立

定量因素应当是在立法过程中被设立的。但是，定量因素的完善离不开司法机关主观能动性的发挥。应当由国家一级的立法机关对情节加重犯中定量因素的种类做出明确的规定，由各省的立法机关参照种类的规定，根据最高立法机关设立的制定系数的原则，结合本省的实际情况对权数予以设定。之后，由司法机关完成相乘之后的相加，即对于复杂案件采取“加权求和”的方法。     

Validity Issues in Test Speededness

Speededness refers to the situation where the time limits on a standardized test do not allow substantial numbers of examinees to fully consider all test items. When tests are not intended to measure speed of responding, speededness introduces a severe threat to the validity of interpretations based on test scores. In this article, we describe test speededness, its potential threats to validity, and traditional and modern methods that can be used to assess the presence of speededness. We argue that more attention must be paid to this issue and that more research must be done to set appropriate time limits on power tests so that speed of responding does not interfere with the construct measured.     

不同运动等级青年男子乳酸阈、心肺功能的比较研究

选取体育专业足球队学生（专业组）、非体育专业不运动学生（对照组）和体育锻炼持续一年以上的学生（锻炼组）为实验对象，采用德国h／p／cosmos跑台和美国MAX-Ⅱ心肺测试系统等设备测定其在运动过程中心肺功能各指标及血乳酸浓度的变化并进行综合评价。结果显示，专业组和锻炼组达到乳酸阈时的跑速、血乳酸浓度高于对照组；乳酸闽和最大吸氧量（VO2max）时的摄氧量（VO2）、氧脉搏（O2P）、每分通气量（VE）、跑速等指标均高于对照组。     

篮球专业学生功能性运动测试及结果研究

本文通过文献资料、实验法等,运用功能性运动测试(FMS),对某高校2011级部分篮球专选学生进行损伤情况调查及实验测试。结果表明:出现过轻度的人数为33人次,占总人数的89.1%,出现过中度损伤的人数为21人次,占总人数的56.7%,有过重度损伤经历的有7人次,占总人数的18.9%,损伤类型依次为皮肤擦伤、扭伤、肌肉拉伤、关节脱臼、骨折。最容易出现损伤的部位为手指、手腕关节。FMS测试6名学生中没有出现不及格现象。结论:体育教育专业篮球专项学生应加强对运动员损伤预防及伤后处理的教育,提高自我保护意识;加强场地器材和医务监督,从思想上重视损伤带来的危害。     

软件测试中选择有效测试技术的一种方法

软件测试对于软件发展具有重要作用,有多种不同的软件测试技术,如何从中选择一个高效的测试技术是软件测试管理中的一个重要问题。本文针对该问题分析了覆盖水平与测试技术有效性之间的关系,并以路径覆盖测试和判定覆盖测试这两种方法为例进行了实验研究,结果表明在缺陷检出率及测试用例数与测试覆盖率之间遵循幂指数关系,这种幂指数关系有助于测试人员在给定覆盖率时,对缺陷发现率和需要的测试用例数进行预测。     

新型废弃物环保处理装置监测

废弃物处理产生的污染物能否得到有效控制,事关环境保护与人体健康,也关系到废弃物处理的可持续发展和废弃物能源化利用的关键所在。本研究通过对"ERCM废弃物环保处理装置"进行监测,污染物排放均达到相应标准要求,填补了二英等污染物一直没有得到有效解决的空白。     

Temporal specificity of training: intra-day effects on biochemical responses and Olympic-Weightlifting performances

The aim of this study was to investigate the performance of an Olympic-Weightlifting session training at three times of the day on the performance related to biochemical responses. Nine weightlifters (21 ± 0.5 years) performed, in randomised order, on three Olympic-Weightlifting training (snatch, clean and jerk) sessions (08:00 a.m., 02:00 p. m., 06:00 p. m.). Blood samples were collected: before, 3 min and 48 h after each training session. Haematological parameters and markers of muscle injury were assessed. Resting oral temperature and rating of perceived exertion (RPE) were also assessed during each session. ANOVA showed that the performance was better (P < 0.001) at 02:00 p. m. with a less RPE (P < 0.01) compared to the morning and the evening sessions while there was higher (P < 0.05) oral temperature at 06:00 p. m. versus 08:00 a.m. and 02:00 p. m. Muscle damage changed immediately (without significant effect after 48 h) after the training sessions with lower values ??in the evening compared to the morning. In conclusion, the afternoon training is more effective than morning or evening sessions for weightlifters. Therefore, coaches and weightlifters should be advised to schedule their training session in the afternoon hour.
