论模糊逻辑的有效性

为了符合经典有效性标准,我国学者王国俊教授和婓道武教授分别构造了模糊形式演绎系统L*和模糊谓词一阶形式系统K*,这反驳了模糊逻辑缺乏逻辑基础的谬论。然而随着现代科学日益进步和逻辑学分支学科的不断发展,经典逻辑过于狭隘的非此即彼的模式及其有效性标准显得越来越过时了。非形式逻辑通过对经典有效性标准的限制和修改,已形成归纳有效性、实质有效性等另类的有效性概念。模糊逻辑用发展了的有效性标准来评估更能体现其理论存在的价值和自身特点。

Are students really connected? Predicting college adjustment from social network usage

The rapid growth in popularity of social networking sites has spurred research exploring the impact of usage in a variety of areas. The current study furthered this line of research by examining the relationships between social network usage and adjustment to college in the academic, social, personal-emotional and university affiliation domains. Realising the number of students with social networking accounts, some universities have developed strategic plans for social media. Thus, this study also compared two universities, one with a social media strategic plan and one without, to determine if the planning process had an influence on students. Results indicated that social network usage was related to college adjustment. Specifically, those students who reported higher rates of social media use reported lower levels of adjustment to college in all domains. However, there were no differences between the two universities, indicating that having a social media strategic plan does not influence students in the area of college adjustment. These results are discussed in light of retention rates and changing practices within higher education.     

Social capital in the classroom: a study of in-class social capital and school adjustment

Social capital is generally considered beneficial for students’ school adjustment. This paper argues that social relationships among pupils generate social capital at both the individual and the class levels, and that each has its unique effect on pupils’ performance and well-being. The sample in this study consists of 1036 children in 60 first-grade classes in 46 Dutch elementary schools. Multilevel regression results show that a substantial proportion of the variance in school adjustment can be attributed to the class level and that both individual-level and classroom-level social capital have substantial effects on school adjustment. At the individual level, the size of one’s network is more important than its structure. At the collective level, social capital also has a ‘dark side’ because it can have negative effects on adjustment, lowering the academic performance in a class.     

An information delivery model for banking business

Banking is an enterprise consists of different levels of users with the requirement of different levels of information. We propose an information delivery model for banking business which takes information from business analysis and finds the best user for this information with respect to criteria and delivers the multi criteria reporting. There are many multi criteria decision making techniques [MCDM] available to find the best alternative in MCDM problem. We applied fuzzy MCDM technique which resolves inconsistency and uncertainty issues involved in decision making of information delivery for bank users. This model classifies most preferred user to least preferred user for the given information using fuzzy score. This information delivery model and its layers can be applied to other domains to build information delivery model.     

结构调整、范式转换与“第三次工业革命”

我国正处于结构调整和发展方式转变的关键时期。文章用演化理论阐释了工业革命的性质,及其与科技革命和范式转换的联系与区别,探析了第三次工业革命的内涵。第三次工业革命在技术、生产和组织上,表现出与当前经济范式截然不同的特征。尽管支撑第三次工业革命的主要技术和产业尚未完全成熟,但是第三次工业革命已现端倪,不容忽视。第三次工业革命在给中国新兴产业和社会发展带来历史机遇的同时,也对传统自上而下的管理方式提出挑战。为了适应生产力发展的需要,传统管理方式需从直接干预向营造环境转变。

竞技体育发展方式基本理论问题探析

摘要：转变发展方式是我国“十二五”期间体育事业发展的主线,对竞技体育发展方式基本理论问题的研究至关重要。为深化对于竞技体育发展方式转变的理论认识,运用文献资料法,在认识竞技体育发展方式概念、分类和评价的基础上,提出了竞技体育发展方式转变的目标、要求和支撑条件。研究认为：1）竞技体育发展方式转变的目标为集约、均衡、和谐、常规化的发展等。2）要求为科学认识转向、转幅、转速问题,合理处理旧发展方式与新发展方式的关系,正确处理转变的短期效应与长期效应的关系。3）竞技体育发展方式转变的支撑条件为人才资源、科技和管理创新、变革的共识性认识等。为竞技体育发展方式的转变研究提供学理上的支撑。     

我国高校体育本科专业设置发展演变研究*

依据我国普通高校本科专业目录的四次调整为蓝本,对我国体育学本科专业结构的发展变化进行研究。研究发现:体育教育、社会体育指导与管理以及运动人体科学成为为我国体育本科专业的三大基本专业,专业数量得到进一步控制,专业名称得以科学规范,进一步明确了专业内涵与培养目标。但专业建设也还存在发展速度过快,质量不高;规模过大,效益较低;结构失衡,分布不均;自我发展速度与社会需求脱节;固守传统人才培养模式,缺乏创新机制等问题。建议制定与实施体育学本科专业发展规范,拓宽专业口径,调整专业结构,加强体育学学科理论研究等。
