基于混沌振荡粒子群优化的FCM文本聚类方法

针对模糊C均值聚类算法易于陷入局部极值的问题,设计了一种基于混沌振荡粒子群优化的模糊C均值聚类方法。该方法在标准PSO算法中设计了一个振荡环节并引入混沌理论以增加算法的多样性和收敛性,接着把优化后的PSO算法和模糊C均值聚类算法相结合。文本聚类的仿真实验表明,相对于PSO-FCM算法和FCM算法,CCPSO-FCM算法具有良好的全局搜索能力和收敛速度,聚类效果良好。     

关于牛顿“碑文”翻译的一个争论

诗人蒲柏曾给牛顿拟过一个碑文,后来虽未予采用,但该诗却流传甚广,很多关于牛顿的文章都引用过它。其后,另一个英国诗人J．C．斯奎尔,按同样的形式又续了一首诗。对于后一首诗准确的理解和翻译,曾经引起了一场很热烈的争论。     

Public and private value in citizen participation in E-governance: Evidence from a government-sponsored green commuting platform

Citizen participation in E-governance is, essentially, a social exchange between individuals and their government through which the citizen creates public value as well as acquires private value. The direct effects of participation antecedents on participation outcomes have been fully examined, but few researchers have investigated the internal mechanism of citizen participation at the level of psychological value perception. The roles of perceived public and private value between the participation antecedents and outcomes remain unclear. Private value merits careful research in particular as the E-governance environment is being shaped by increasing privatization and continuous IT innovation. Based on the cognitive integration theory and the civic voluntarism model, this paper proposes a theoretical framework to examine the mediating roles of two values. We built a complete research model encompassing ten hypotheses centered on citizen e-participation in the context of green commuting governance. By analyzing survey data on a green commuting platform, we demonstrate the significant mediating effects of these two values and greater effect of private value acquisition on continuous e-participation intentions than public value creation. Our results have important research implications in regards to the roles of perceived values in participation, especially perceived private value.

“5C”语篇分析模式在大学英语阅读教学中的应用

将“5C”语篇分析模式运用于大学英语课堂教学,可以从微观和宏观两个方面进行分析。微观结构分析有助于学生对篇章的理解由词、句层面向语篇层面拓展,培养学生理解句与句、段与段之间的衔接及逻辑关系,注重对篇章的整体理解;宏观结构分析则从篇章结构、文化及语境等方面引导学生理解主题思想和作者意图,发掘深层内涵。     

Fostering Social and Emotional Skills for Well-Being and Social Progress

Children need a balanced set of cognitive, social and emotional capabilities to adapt to today's demanding, changing and unpredictable world. OECD countries and partner economies recognise the importance on the holistic development of individuals. However, there are big gaps between stakeholders' knowledge, expectations and practices on how to foster such skills. This paper presents evidence on the importance of social and emotional skills; on how policy makers and schools are currently enhancing and monitoring such skills; and, on the existing gaps between knowledge, expectations and practices to mobilise these skills. The paper concludes by pointing ways in which education stakeholders can do more to better develop and mobilise the skills that drive individual's well-being and social progress. The paper draws on findings and frameworks that are being published in a full OECD report entitled ‘Skills for Social Progress: the Power of Social and Emotional Skills’ in the first half of 2015.     

Open access to data: An ideal professed but not practised

Data-sharing is an essential tool for replication, validation and extension of empirical results. Using a hand-collected data set describing the data-sharing behaviour of 488 randomly selected empirical researchers, we provide evidence that most researchers in economics and management do not share their data voluntarily. We derive testable hypotheses based on the theoretical literature on information-sharing and relate data-sharing to observable characteristics of researchers. We find empirical support for the hypotheses that voluntary data-sharing significantly increases with (a) academic tenure, (b) the quality of researchers, (c) the share of published articles subject to a mandatory data-disclosure policy of journals, and (d) personal attitudes towards “open science” principles. On the basis of our empirical evidence, we discuss a set of policy recommendations.
