用稳态近似法推导反应速度方程时应注意的一个问题

用稳态近似法推导反应的速度方程时,最后所导出的速度方程有时会出现由不不同数值而组成的系数。针对这个问题,本文指出了两种避免出现该问题的方法。     

试论心理学课堂教学运行机制的整体优化

整体优化课堂教学运行机制,是显著提高师范院校公修课心理学教学质量和效率的有效途径。本文运用系统论、控制论和信息论原理,从心理学课堂教学过程的内部结构、运行程序与其功能之间的本质性联系,从课堂教学中的优化控制和课堂教学中信息的优化传递几个方面,探索和论述了优化课堂运行机制,从根本上提高心理学课堂教学质量和效率的问题。     

论"万里模式"

“万里模式”在宏观高等教育体系方面的特点是从既不同于国立高校,又不同于一般意义上的民办高校两个侧面体现出来的,它是国立高校的拓展,又是对民办高校的完善;“万里模式”的办学理念是“以生为本,以师立校,面向市场,国际接轨”。“以生为本”是办学之纲。“万里模式”的办学机制是与其全新的办学体制密不可分的,推动这一机制运行的是以万里精神为核心的“文化力”,这一机制形成的关键是将市场经济的规则引入到高校管理内部。     

关于高校学生党员先进性教育长效机制建立的思考

高校学生党员的先进性教育在全党的先进性教育中有着特别重要的地位。高校各级党组织要提高认识,加强领导,深入调查研究,突出重点,整合资源,积极探索建立健全高校学生党员先进性教育长效机制的原则、框架、方法和途径,使党员教育经常化、党员管理规范化、党内生活制度化、服务群众长期化、发挥作用具体化,培养和造就千百万社会主义事业的合格建设者和可靠接班人。     

一种基于服务质量的网格服务发现机制

网格服务体系结构的出现对网格服务发现提出了挑战,UDDI上基于关键词和简单分类的服务发现机制已经不能很好满足需要.本文在分析现有相关研究的基础上,提出了基于服务质量的网格服务发现机制,引入服务质量相似度的概念,为网格服务发现提供了一种有效可行的方法.     

和谐社会视野下的企业社会责任标准SA8000

SA8000是全球第一个可用于第三方认证的企业社会责任国际标准,是国际社会责任运动的产物。SA8000旨在通过有道德的采购活动,改善全球劳工的工作条件,体现了对劳工权益的保护。在构建社会主义和谐社会的大背景下,针对我国目前劳工权益法律保护比较薄弱的现状,推行SA8000可以有效地协调劳资双方的关系,推动和谐劳动关系的形成与发展,从而促进社会主义和谐社会目标的实现。     

Exposing the dark side,an exploration of the influence social capital has upon parental sports volunteers

This study explored the influence social capital had over parental sports volunteers who are considered to be of paramount importance in the delivery of UK sports initiatives. A review of the relevant literature identifies and discusses the complexities within the debate to define social capital while human and cultural capital emerge as an essential element in the production of parental volunteers’ ability to access opportunities through a process of bonding or bridging social networks. This study used a grounded research focused on the use of semi-structured interviews and research diaries with (n = 8) study participants. The results from this study, which were analysed through a Bourdieuan perspective, suggested the process that recruits parental volunteers is exclusive; furthermore, the results show the insidious presences of the dark side of social capital, which affected the respondents by reinforcing exclusive ties and identities, which was found to exclude outsiders while reproducing a dominant social hierarchy. The paper concludes by considering the implications of the study for future practical and academic applications of social capital production within sports volunteerism.     

“Sport for Development” in developing countries: The case of the Vilas Olímpicas do Rio de Janeiro

The benefits of sport for general social outcomes has permeated sport policy in Brazil since the beginning of the twentieth century, but recently the jargon of “development through sport” is more overtly informing public policy and government action in this field. Despite increased uptake of the positive discourse of “sport as a development tool”, the reality for government-funded and -run “sport for development” programs is one far removed from enjoying the attention and financial investment needed to reach their stated development goals. This paper focuses on one such program: the Vilas Olímpicas do Rio de Janeiro. When analysing the specific matters associated with the management of this program three themes were identified that encapsulate the main issues that emerged during the analysis: partnerships, conflicting aims, and community involvement. These themes are analysed in light of the literature that discusses the application of “sport for development” programs worldwide and we conclude with some questions on the applicability of well-defined frameworks and approaches to such programs when these programs themselves tend to operate in very ill-defined and unstable environments.

心理学视域下校园欺凌的形成机理及对策

校园欺凌是国内外中小学中普遍存在的现象,从心理学角度考察其成因、探索相应干预措施有着重要意义。有关欺凌事件直接参与者的研究表明:部分欺凌者存在一定程度的反社会行为或认知特征,欺凌行为也是青春期个体获取、维护社会支配地位的一种手段;某些"另类"特征、情绪和社会交往问题会让儿童青少年成为易受欺凌的对象;欺凌和受欺凌都可能导致个体情绪、行为等方面的适应障碍,其不良影响甚至会延续相当长的时间;欺凌-受欺凌者是最不稳定的一类角色,兼具欺凌者与受欺凌者两者的缺点,适应状况通常最差。班级内的同伴生态、旁观者的行为和朋友关系都会影响欺凌事件的发生几率及所导致的后果。某些家庭和父母特征也是与欺凌行为联系密切的危险性或保护性因素。积极的师生关系有助于减少欺凌事件的发生,也能对其后果起到缓冲作用。但缺乏培训的父母和教师,通常无法及时准确地识别欺凌事件并做出有效应对。当前教育实践中,可以有效防控校园欺凌的措施大致可以划分为两类;一是面向特定相关群体的单水平干预,二是要求学生、家长、教职员工等都要参与其中的多水平干预。
