研究新中国成立70年来体育教育专业人才培养特征与演变规律,是呈现体育教育专业发展历史的需要,是推动体育教育专业发展和改革的一项基础性工程。采用文献资料法、历史法、专家访谈法和逻辑分析法,对体育教育专业发展规模、专业定位、培养方案、课程设置、教学模式等方面开展研究,结果表明:新中国成立70年来,体育教育专业经历了学习与移植、探索与挫折、混乱与恢复、开放与改革、提速与跨越、实践与创新的演变过程。表现出专业规模不断扩大、培养目标由单一向多元发展、课程设置逐渐模块化和弹性化、选修课和实践课学时逐步增加、总学分缓慢降低、人才培养模式多样、教学方法不断更新等特征。这些演变是基于国际国内的政治、经济、文化和科技发展的历史缘由。当下,专业认证已全面铺开,坚持"一流专业"建设是培养卓越体育教师的根与本。 相似文献

Genetic variation in the angiotensin II type 1 receptor (AT1R) has an important effect on the outcome of acute coronary syndrome (ACS) initiated treatment with captopril. This study aims to investigate the impact of genetic polymorphism of AT1R (rs5186 and rs275651) on the ACS outcome in Iraqi patients treated with captopril. A total of 250 Iraqi individuals with ACS were included in this case—control study and they were divided into two study groups; Study group 1 included 125 participants who were prescribed captopril, 25 mg twice daily and study group 2 included 125 participants who received no captopril as part of their ACS treatment (control study). The AT1R gene (rs5186) CC genotype was found to be associated with ST-elevation myocardial infarction (STEMI) (Odd’s ratio (O.R) = 1.2, P = 0.7), while AC was associated with Non-ST-elevation myocardial infarction (NSTEMI) and unstable angina (UA) (O.R = 1.2, P = 0.8). AC genotype is more prone to have Percutaneous coronary intervention (PCI) after ACS attack (O.R = 1.2, P = 0.6). CC genotype had a risk to get less improvement (O.R = 1.6, P = 0.5), so might require higher doses of captopril during acute coronary insult. The AT1R gene (rs275651) AA genotype was associated with UA (O.R = 1.3, P = 0.9). AA and AT genotypes were more prone to have PCI after ACS attack (O.R = 3.9 P = 0.2, O.R = 3.5, P = 0.3 respectively) and thus requiring higher doses of captopril. We conclude that the AT1R rs5186, rs275651 genetic polymorphisms might partially affect the clinical outcome of ACS patients treated with captopril and might have captopril resistance which requires higher doses. 相似文献

Numerous motor abilities depend on the activity of proprioceptors, which has been suggested to be genetically determined. To test this hypothesis, the control of torque generated by knee extensors and knee position was studied in 30 father–son pairs both before and immediately after running. After stabilisation of the participant in a sitting position, the knee joint of his dominant leg was flexed to 90°, and the maximal voluntary torque (MVT) of the dominant knee extensors under static conditions was measured. The participant then tried five times to produce 50% of the MVT. Next, the participant extended the knee to 45° five times without visual control. Significant correlations between the reproducibility of successive trials for groups of fathers and their sons were found. The correlation coefficients for the repeatability of the knee extension torque were 0.69 (confidence interval [CI] = 0.45–0.84; P < 0.01) and 0.75 (CI = 0.54–0.87; P < 0.01) before and after the fatiguing exercise, respectively, whereas the coefficient for the reproducibility of positioning the knee was 0.49 (CI = 0.16–0.72; P < 0.01) after the fatiguing exercise. Our results indicate a significant influence of hereditary factors on the control of limb torque and position. 相似文献

现有关税收优惠政策对企业创新活动影响的文献缺乏从整个创新链的全角度揭示税收优惠政策是否真正提高企业创新能力的探索。基于中关村科技型企业数据,本文选取税收优惠政策中典型的政策工具“研发费用加计扣除”作为研究对象,有别于已有主要从“投入”视角关注研发费用加计扣除引导作用的研究,从“投入-产出-收益”的创新链全视角,将创新过程分为技术研发阶段与技术转化阶段,以揭示研发费用加计扣除政策是否真的提升了企业创新能力。基于PSM-DID方法的实证研究结果发现:在投入端,研发费用加计扣除政策显著提高了企业的研发投入规模与强度;在产出端,研发费用加计扣除政策仅促进了研发产出规模的提升,而对于产出强度则无显著影响;在收益端,研发费用加计扣除对收益规模与强度同样有显著的促进作用。本文的发现肯定了我国研发费用加计扣除政策的引导作用,以及其在企业创新能力提升中发挥的积极作用。本文的研究思路为揭示政府创新激励政策的效果提供了新视角,研究发现为从创新链与企业创新能力的角度思考和改善政府研发税收优惠政策的管理和实施提供了新证据。 相似文献

职业裁判制度是足球职业化发展到一定阶段的必然产物,其引入将有力提升我国裁判执法水平,助推我国足球事业发展。认为,职业裁判是职业联赛健康发展的关键力量,是足球运动技术发展的客观要求,是提升足球裁判整体水平、统一集中管理的需要。目前,我国的足球裁判存在基数小、水平低、待遇低、环境差等问题。只引入足球职业裁判制度而无配套措施,可能无法解决根本矛盾;目前的国内联赛规模也还无法满足职业裁判发展需求,职业转换难度大及退休保障不足,也阻碍着我国职业足球裁判制度的实施。指出,应加快足球联赛发展,与职业裁判发展互促互进;健全体育裁判法律法规,改革职业裁判组织管理方式;建立健全职业裁判员的薪酬和退休保障体系;注重青少年裁判培养,全面提升在职裁判员业务水平。多管齐下,使足球职业裁判制度发挥更好的效果。 相似文献

外部网络关系对企业双元创新的影响结果存在较大争议,企业维持何种状态的外部网络关系会促进双元创新,影响机理中知识吸收能力起到怎样的作用,这是亟需研究的问题。对387家企业为样本进行问卷调查,运用结构方程模型法,以知识获取能力和知识实现能力为双重中介,探析外部网络关系对企业双元创新的影响。研究结果表明:外部网络关系不同维度对双元创新具有差异化影响;网络关系强度和网络关系密度的提高以及网络关系深度的适度降低有利于渐进性创新,网络关系深度和网络关系密度的提高以及网络关系强度的适度降低更有利于突破性创新;知识吸收能力在外部网络关系对双元创新的影响中发挥部分中介作用。 相似文献

With greater access to computational resources, people use search to address many everyday challenges in their lives, including solving technology problems. Although there are now many useful ‘how-to’ resources online (especially videos on YouTube), it can still be difficult to identify, understand, and resolve certain kinds of technical problem. While research tasks have been studied for many years and we know the tactics people use, we know far less about searchers’ tactics for how-to technical tasks that involve actually being able to apply found information to resolve a problem. Crucial to our study was developing and studying a highly realistic, how-to technical task, for which there was no single guidance resource: making a phone safe for a child. After providing 39 participants with an actual phone to fix, and a search engine to perform the task, we analysed their search tactics using retrospective cued think aloud interviews. Our primary contribution is a set of 77 tactics used, in three categories, along with detail of how common they were. We conclude that people had a lot of tactics in their repertoire. Although it was not hard for participants to find relevant information, what was hard was for participants to find information they could use; indeed only 23% of participants successfully completed the entire task. Domain knowledge affected the choice of tactics used (although not necessarily towards better task success). We discuss these influences and make design recommendations for how future search systems can support those in resolving how-to technical tasks. 相似文献
