浅谈二语习得互动假说

互动假说自1985年问世以来就受到广泛关注,现已成为二语习得界普遍认可的理论之一。交际中的互动调整有助于语言输入的理解,输出是对输入的检验。在二语习得中．输入、输出和互动三者密切相连。对输入假说、输出假说进行分析．有助于更好地了解互动在二语习得过程中的作用．加深对互动假说理论的理解．把握其发展动向。     

A Consideration of Why Active Participation in Sport and Leisure Might Reduce Criminal Behaviour

This paper contributes to sport, sociology and the body literature by exploring the ‘exposure and effect’ of culture, in particular bodily practices placed on three adolescent swimmers immersed in the Australian swimming culture using an ethnographic framework. The research reported is particularly notable as it addresses two distinct time points in the swimmers’ lives. The first section explores the adolescent experiences of three female swimmers within the cultural context of Australian swimming by articulating some of the specific body practices and ‘memes’ (ideas, symbols and practices) that they were exposed to and/or engaged within relation to the body. The second section of this paper focuses on the same three swimmers in the ‘present day’, some 10–30 years after being immersed in the Australian swimming culture as adolescents. It excavates their body practices and the relationships they now have with their body, and thus pursues the sustained impact of the body practices and ‘memes’ they were exposed to as adolescents. Analysis employs concepts drawn mainly from Foucault, particularly his thesis in regard to ‘disciplinary power’, ‘regulation’ ‘classification’ and ‘surveillance’. At a club (amateur) and National level, Australian swimming is revealed as an institution, a site and culture where particular techniques of power have become concentrated and have been brought to bear on individuals in systematic ways, with sometimes damaging effects arising for athletes’ long-term health and well-being, particularly if the individuals concerned continue to engage with cultural practices in regard to the body post-career.     

‘Governmentality’ in the origins of European female PE and sport: the Spanish case study (1883–1936)

The purpose of the paper is twofold: (1) to contribute to the analysis of the origins of modern European female PE and sports from a power perspective, inspired by Foucault's work; and (2) to present a detailed analysis of female PE and sport in Spain (1883–1936) as a specific European case study. It is argued that these physical activities could be conceived in the Spanish case as part of a specific kind of ‘governmentality’ with a dual nature. On the one hand they represented disciplinary ‘technologies of power’ over the female body. Selected physical activities—dictated mainly from the hygienic-moral position of the Regeneracionistas (‘Regenerationists’)—were exerted as a kind of ‘bio-power’ for the control of the female population. On the other hand, such kind of activities (especially sports) represented certain ‘technologies of the self’ for middle and upper class women. Through participation in sports, women gained a more active and public role in the Spanish society of the era, obtaining some degree of autonomy in self-governance over their bodies and their lives.     

邹文海关于自由与权力的研究

邹文海作为中国早期杰出的政治学家,其对“自由与权力”的思考详见于他早期的著作和政论中。尽管他的思考是立足于当时的时代背景和政治局势,但是他对于“自由与权力”的种种创造性见解对于今天的政治学研究主题仍具有深远的影响和借鉴意义。邹文海创造性地吸收了社会学、心理学和文化人类学的观点,提出自由是一种心理感觉,权力是建立在人民同意的基础之上的。他从社会习俗的角度出发,对二者进行论证,并辩证地认为自由与权力是一种相反相成的关系。     

检察一体化的价值定位

检察权是法律监督权。检察机关(或检察官)是检察权的载体所在,它以法律监督机关的形式呈现出来。检察一体化是检察机关行使检察权工作的表现形式。对检察权、检察机关与检察一体化的探讨均须立足于既有法律秩序进行阐述才更有现实意义。     

Numerical investigation on the flow and power of small-sized multi-bladed straight Darrieus wind turbine

Straight Darrieus wind turbine has attractive characteristics such as the ability to accept wind from random direction and easy installation and maintenance. But its aerodynamic performance is very complicated,especially for the existence of dynamic stall. How to get better aerodynamic performance arouses lots of interests in the design procedure of a straight Darrieus wind turbine. In this paper,mainly the effects of number of blades and tip speed ratio are discussed. Based on the numerical investigation,an assumed asymmetric straight Darrieus wind turbine is proposed to improve the averaged power coefficient. As to the numerical method,the flow around the turbine is simulated by solving the 2D unsteady Navier-Stokes equation combined with continuous equation. The time marching method on a body-fitted coordinate system based on MAC (Marker-and-Cell) method is used. O-type grid is generated for the whole calculation domain. The characteristics of tangential and normal force are discussed related with dynamic stall of the blade. Averaged power coefficient per period of rotating is calculated to evaluate the eligibility of the turbine.     

一种负反馈放大器的计算方法

电压增益、输入电阻、输出电阻是放大电路的三项指标，一般用微变等效电路法计算，但是在负反馈放大器中，由于引入反馈支路，用微变等效电路法计算上述指标很困难。本文给出一种消去反馈支路的方法，使负反馈放大器的计算得以简化。
