以社会学的视角看中国全运会的“东道主金牌峰现象”

基于为我国全运会的健康发展提供有用参考的主导思想,运用数据统计和逻辑推理等研究方法,在阐述了为什么"东道主金牌峰现象"假说成立的基础上,重点分析了全运会体育功能的政治目标置换、全运会体育功能的经济目标接轨、全运会发展所处的特殊历史时期等全运会中出现"东道主金牌峰现象"的主要原因,并且就如何保证全运会的健康发展问题,针对性地提出了如建立制度化的制度管理制度系统、树立法律规范的市场化建设目标、新规则制定应论证其正负面影响、把基础理论研究提到一个新高度等建议.

纳米材料的研究进展

由于纳米微粒的小尺寸效应、表面效应、量子尺寸效应和宏观量子隧道效应等使得它们在磁、光、电、敏感等方面呈现常规材料不具备的特性,因此其在磁性材料、光学材料、电子材料以及高致密度材料的烧结、传感、催化、陶瓷增韧等方面有广阔的应用前景,目前研究者颇多.本文主要从纳米材料制备与表征的方法以及纳米材料的应用方面总结了近几年来纳米材料的研究进展.     

关于高校二级工会建设的几点思考

高校二级工会是面向教职工,直接与一线教职工打交道的平台,是实现上情下达、下情上达的重要桥梁。因此,高校二级工会应充分发挥部门工会的组织协调作用,在队伍建设、制度建设、作风建设、共建二级教工之家四方面加强自身建设,并对二级工会怎样得到大多数教职工的理解、支持和认同提出三点建议,充分发挥二级工会的作用,使工会真正成为教职工之家。

Effects of blood flow restriction without additional exercise on strength reductions and muscular atrophy following immobilization:A systematic review

Purpose:To investigate whether blood flow restriction(BFR) without concomitant exercise mitigated strength reduction and atrophy of thigh muscles in subjects under immobilization for lower limbs.Methods:The following databases were searched:PubMed,CINAHL,PEDro,Web of Science,Central,and Scopus.Results:The search identified 3 eligible studies,and the total sample in the identified studies consisted of 38 participants.Isokinetic and isometric torque of the knee flexors and extensors was examined in 2 studies.Cross-sectional area of thigh muscles was evaluated in 1 study,and thigh girth was measured in 2 studies.The BFR protocol was 5 sets of 5 min of occlusion and 3 min of free flow,twice daily for approximately 2 weeks.As a whole,the included studies indicate that BFR without exercise is able to minimize strength reduction and muscular atrophy after immobilization.It is crucial to emphasize,however,that the included studies showed a high risk of bias,especially regarding allocation concealment,blinding of outcome assessment,intention-to-treat analyses,and group similarity at baseline.Conclusion:Although potentially useful,the high risk of bias presented by original stodies limits the indication of BFR without concomitant exercise as an effective countermeasure against strength reduction and atrophy mediated by immobilization.     

胡适的媒介独立传播思想

媒介独立是胡适传播思想的核心。胡适认为大众媒介必须独立于官方机构或党派,刊发具有独立思想的言论,成为公共领域,杜绝成为利益团体的喉舌。胡适还认为,媒介独立包括新闻传播者的身份独立,新闻传播者身份独立是保证媒介的思想自由,言论公正的前提。胡适特别强调新闻传播者身份虽然独立,但不能与政府为敌,言论必须"敬慎无所苟",做政府的"诤友"。
