恩格斯历史合力内涵辨正   总被引：1，自引：0，他引：1  

冯跃民 《廊坊师范学院学报》2006,22(4):52-54

恩格斯历史合力概念不是指经济因素唯一起作用的结果,也不是指人类意志单独起作用的结果,而是包括经济因素、上层建筑、人的意志选择等等各种历史参与因素在内的所有因素的共同作用和相互作用形成的力量。这可从恩格斯历史合力概念提出的背景、恩格斯对社会科学“力”的概念使用界定、致约.布洛赫的信写作的直接动因以及恩格斯的理论论述得到确证。  相似文献

近百年来,我国图书馆的业务经历了由近代向现代管理模式的转变。从转变机制来看,图书馆业务管理模式的转变主要是靠他变机制的力量推动。我国图书馆业务管理模式整体变革,应从建立国家图书馆事业管理及协调机构、形成大的图书馆事业集团、优化图书馆内部业务管理部门入手,推进管理模式变革。参考文献11。  相似文献   

Specific tackling situations affect the biomechanical demands experienced by rugby union players     

Elena Seminati  Dario Cazzola  Ezio Preatoni  Grant Trewartha 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(1):58-75

Tackling in Rugby Union is an open skill which can involve high-speed collisions and is the match event associated with the greatest proportion of injuries. This study aimed to analyse the biomechanics of rugby tackling under three conditions: from a stationary position, with dominant and non-dominant shoulder, and moving forward, with dominant shoulder. A specially devised contact simulator, a 50-kg punch bag instrumented with pressure sensors, was translated towards the tackler (n = 15) to evaluate the effect of laterality and tackling approach on the external loads absorbed by the tackler, on head and trunk motion, and on trunk muscle activities. Peak impact force was substantially higher in the stationary dominant (2.84 ± 0.74 kN) than in the stationary non-dominant condition (2.44 ± 0.64 kN), but lower than in the moving condition (3.40 ± 0.86 kN). Muscle activation started on average 300 ms before impact, with higher activation for impact-side trapezius and non-impact-side erector spinae and gluteus maximus muscles. Players’ technique for non-dominant-side tackles was less compliant with current coaching recommendations in terms of cervical motion (more neck flexion and lateral bending in the stationary non-dominant condition) and players could benefit from specific coaching focus on non-dominant-side tackles.  相似文献   

False-performance feedback does not affect punching forces and pacing of elite boxers     

Israel Halperin  Dale W. Chapman  Kevin G. Thompson  Chris Abbiss 《Journal of sports sciences》2019,37(1):59-66

Prior research indicates that providing participants with positive augmented feedback tends to enhance motor learning and performance, whereas the opposite occurs with negative feedback. However, the majority of studies were conducted with untrained participants performing unfamiliar motor tasks and so it remains unclear if elite athletes completing familiar tasks respond in a similar fashion. Thus, this study investigated the effects of three different versions of false-performance feedback on punching force (N), pacing (force over time) and ratings of perceived exertion (RPE) in 15 elite amateur male boxers. Athletes completed a simulated boxing bout consisting of three rounds with 84 maximal effort punches delivered to a punching integrator on four separate days. Day one was a familiarisation session in which no feedback was provided. In the following three days athletes randomly received false-positive, false-negative and false-neutral feedback on their punching performance between each round. No statistical or meaningful differences were observed in punching forces, pacing or RPE between conditions (P > 0.05; ≤ 2%). These null results could stem from the elite status of the athletes involved, the focus on performance rather than learning, or they may indicate that false feedback has a less potent effect on performance than previously thought.  相似文献
