坚持以人为本的研究性学习--"邓小平理论和‘三个代表’重要思想概论"课的社会实践活动

在“邓小平理论和‘三个代表’重要思想概论”课的教学中,如何找到一条既能体现“两课”的导向作用,又使学生乐于接受的途径,成为“两课”教师经常讨论的问题。在实践中,我总结出了坚持以人为本的研究性学习,坚持社会实践活动是行之有效的途径。研究性学习内容丰富、形式多样,可以提高大学生思想理论素质、提高学生综合素质、锻炼能力。研究性学习需要有效的组织机制和学习制度保障。     

Reliability of arterial spin labelling measurements of perfusion within the quadriceps during steady-state exercise

Arterial spin labelling (ASL) provides a potential method to non-invasively determine muscle blood flow and examine the impact of interventions such as supplementation and training. However, it's a method with intrinsically low signal, leading to limitations in accuracy and temporal resolution. To examine these limitations, the current study measured perfusion via ASL on three occasions in the rectus femoris of 10 healthy adults, during light and moderate exercise, over three different exercise durations. For data sampled over 9 min, light intensity exercise gave an average perfusion of 35.0 ± 5.1 ml/min.100g^?1 with a coefficient of variation (COV) of 16% and single intraclass correlation coefficient (ICC) of 0.67. For the moderate bout, perfusion was 51.3 ± 5.6 ml/min.100g^?1 (COV 10%, ICC 0.82). When the same data were analyzed over 5 min 24 s, perfusion was 37.8 ± 11.13 (COV 30%, ICC 0.13) during light and 49.5 ± 8.8 ml/min.100g^?1 (COV 18%, ICC 0.52) during moderate exercise. When sampling was reduced to 1 min 48 s, perfusion was 41.2 ± 13.7 (COV 33%, ICC 0.26) during light and 49.5 ± 13.6 ml/min.100g^?1 (COV 28%, ICC 0.04) during moderate exercise. For 9 min a significant perfusion difference was found between the exercise intensities; however, this was not the case for sampling over 5 min 24 s or 1 min 48 s. Such findings illustrate the potential of ASL to non-invasively monitor muscle perfusion under steady-state conditions, but highlight that extended exercise protocols are necessary in order to generate date of sufficient reliability to be able to discriminate intervention dependent perfusion differences.     

我国民事诉权理论存在问题及对策分析--由"郑传本名誉侵权案"引出的法律思考

我国民事诉讼理论目前以"二元论"作为通说,由于在实践中存在着一些误区,如把诉权视为审判权的产物、无视当事人的主体地位等,造成一些侵犯当事人诉权的现象.这需要从理论上对诉权做出准确定性,建立起诉权人权化的思想,真正重视当事人及其诉权,从而实现从法官公正到法律制度的公正.     

女子跳水单人10m台动作稳定性研究——以2015年喀山游泳世锦赛跳水比赛为例

采用文献资料、数理统计、逻辑分析、观察等方法对2015年世界游泳锦标赛跳水比赛女子跳水单人10m台的比赛成绩、动作难度、动作组别、最后得分进行对比分析研究,提出影响中国女子跳水单人10m台动作稳定性的因素,为备战2016年里约奥运会女子跳水单人10m台项目的训练提供科学理论依据。     

论法人分支机构

法人分支机构是法人的组成部分 ,具有从属性、区域性、职能性三个特征。在我国民事立法中 ,应当赋予法人分支机构限定性民事主体资格。在民事活动中 ,一般情况下先由分支机构承担民事责任 ;当分支机构的财产不足承担时 ,再由所属法人补充责任。在民事诉讼中 ,法人分支机构具有独立的诉讼主体资格。澄清有关法人分支机构的认识在立法和司法上都有重要的意义。     

Low-intensity electrical muscle stimulation induces significant increases in muscle strength and cardiorespiratory fitness

The aim of this study was to investigate the effect of low-intensity exercise training using belt electrode skeletal muscle electrical stimulation on muscle strength and cardiorespiratory fitness in healthy subjects. Nineteen healthy subjects were allocated into control or intervention groups; in both groups the participants kept regular physical activity while the intervention group underwent 30 min B-SES training at 3–4 METs for four weeks. Knee extensor muscle strength and cardiorespiratory endurance during incremental exercise test were measured at baseline and after four weeks for all participants. The relative change of knee extensor muscle strength in the intervention group was significantly higher than control group (p?p?相似文献   

Effects of load mass carried in a backpack upon respiratory muscle fatigue

Purpose: The purpose of this study was to investigate whether loads carried in a backpack, with a load mass ranging from 0 to 20?kg, causes respiratory muscle fatigue. Methods: Eight males performed four randomised load carriage (LC) trials comprising 60?min walking at 6.5?km?h^?1 wearing a backpack of either 0 (LC₀), 10 (LC₁₀), 15 (LC₁₅) or 20?kg (LC₂₀). Inspiratory (P_Imax) and expiratory (P_Emax) mouth pressures were assessed prior to and immediately following each trial. Pulmonary gas exchange, heart rate (HR), blood lactate and glucose concentration and perceptual responses were recorded during the first and final 60?s of each trial. Results: Group mean P_Imax and P_Emax were unchanged following 60-min load carriage in all conditions (p?>?.05). There was an increase over time in pulmonary gas exchange, HR and perceptions of effort relative to baseline measures during each trial (p?p?>?.05). Conclusions: These findings indicate that sub-maximal walking with no load or carrying 10, 15 or 20?kg in a backpack for up to 60?min does not cause respiratory muscle fatigue despite causing an increase in physiological, metabolic and perceptual parameters.     

行政行为在刑事诉讼中的证据效力研究

行政行为在证据法上的问题,主要是其在诉讼中能否被采纳为证据及其证据的价值问题,也就是它作为证据的可接受性与证据效力问题。     

论中国刑事附带民事诉讼制度的程序调适

在世界范围内,因刑事犯罪行为而引起的民事赔偿,有三种程序立法模式,但以独立民事诉讼的方式来解决刑事犯罪行为的民事赔偿问题已成为司法实践中的一种普遍趋势。中国现行的刑事附带民事诉讼制度,在给被害人带来了一定程序"便利"的同时,两种诉讼在同一程序中并列运行的内在矛盾冲突也显而易见,这既不利于保护被害人的合法权益,也损害了刑事被告人的程序利益,进而影响程序正义的实现。避免这种冲突的有效途径就是将附带民事赔偿部分从刑事诉讼程序中分立出来,而非彼此妥协。     

试析体育舞蹈成套动作的创编

体育舞蹈成套动作的创编，无论是在其教学、训练还是在表演和比赛中都占有十分重要的地位．掌握体育舞蹈的创编技巧，需要根据不同的目的和任务、不同对象的特，长、运动美学法则以及国际发展趋势等几个方面综合考虑、编排过程中要区分动作难度和类型，把握动作的节奏、空间和时间等几个技术要素、成套动作创编要分阶段、有步骤地进行，要科学合理、自然流畅、体现风格，并具有较强的艺术感染力。
