浅谈高校假期公寓开放体系

随着高等教育大众化的普及和参加社会实践活动的大力提倡,近几年假期留校的学生逐渐增多,因此保障好这部分留校学生的安全也显得尤为重要。本文以高校假期公寓管理制度的现状为基础,总结它自身的优点及所存在的问题,探讨改进的策略,最后归纳出了针对高校假期公寓管理制度方面的有效方法。     

马克思的“现代性”之思

＂现代性＂一词是最近几十年来的热门词汇,然而,到底什么是＂现代性＂却是一个值得探讨的问题。尽管马克思从未明确提到过＂现代性＂一词,但是他所关注的范围无不属于现代性范畴。由于理性成为资本主义的核心思维方式,不管是在经济上、文化上还是在政治制度上,资本主义都以理性为自己的立足之本。而从批判黑格尔开始,到最后对资本主义的批判,马克思的目光都没有离开过现代性的范畴。     

Harnessing collective intelligence of Web 2.0: group adoption and use of Internet-based collaboration technologies

Along with the advent of Web 2.0, mass collaboration is of paramount importance in knowledge exploration and diffusion. However, the extent to which Internet-based collaboration technologies can be used to develop new knowledge and to leverage the wisdom of crowds heavily depends on the collective willingness to adopt such tools together. In this study, the adoption and use of instant messaging has been conceptualized as a group-referent intentional social action. The concept of ‘we-intention’, which refers to one's perception of the group acting as a unit, is the focus of our interest. The cognitive, affective and social dimensions that contribute to ‘we-intention’ to adopt and use instant messaging were investigated. A survey was conducted and the findings provided empirical evidence supporting the idea that cognitive, affective and social factors jointly lead to the development of we-intention. This study is expected to provide some useful insights to both researchers and practitioners.

Sampled-data predictive control for uncertain jump systems with partly unknown jump rates and time-varying delay

This paper presents a sampled-data predictive control strategy for a class of uncertain continuous-time Markovian jump linear system (MJLS) with time-varying delay. The system under consideration covers MJLS with completely known jump rates and arbitrary switched linear system. The predictive formulation utilizes both off-line and on-line optimization paradigms. The feasibility of the control scheme and the stability of the closed-loop system are investigated by introducing a modified stochastic invariant ellipsoid. The conditions for the existence of a stabilizing optimal controller for the underlying system are obtained via the semi-definite programming (SDP). A numerical example is given to verify efficiency and potential of the developed approach.     

Examining online consumers’ behavior: A service-oriented view

Retailers’ websites are an important interface between retailers and their customers. The various features and elements that retailers include on their websites play a critical role in attracting customers and ensuring their satisfaction with the online shopping process. By conducting a three-phased study, we identify how the elements of a website shape customers’ salient beliefs. These salient beliefs, in turn, determine the level of customers’ satisfaction with the website. This study provides both theoretical insights into the beliefs of online shoppers and practical insights for retail website operators. Specifically, we argue that when retail websites are constructed to include several specific elements that appeal to the key salient beliefs of information quality, service quality, and system quality, retailers will increase customers’ satisfaction with the online shopping process.     

Facilitating Students’ Conceptual Change and Scientific Reasoning Involving the Unit of Combustion

This article reports research from a 3 year digital learning project to unite conceptual change and scientific reasoning in the learning unit of combustion. One group of students had completed the course combining conceptual change and scientific reasoning. The other group of students received conventional instruction. In addition to the quantitative data, six students from each group were interviewed to evaluate their conceptual change, correct concepts and scientific reasoning. Results indicate that the experimental group’s students significantly outperformed the conventional group on the Combustion Achievement Test (CAT), Scientific Reasoning Test (SRT) and Combustion Dependent Reasoning Test (CDRT). Moreover, the experimental group’s students use higher levels of scientific reasoning more frequently and changed their alternative concepts more successfully than did the conventional group. Furthermore, once the experimental group’s students’ successfully changed their conceptions, their concepts tended to be more stable than the conventional group’s students, even after the 6th week of learning. These results demonstrate that combining conceptual change and scientific reasoning indeed improves students’ conceptual change and scientific reasoning ability more effectively than conventional instruction.     

Contents or ideology? A case study of mathematical teaching in North Korea

This article addresses mathematics education in one of the most closed countries in the world, North Korea. It is known that ideology permeates all aspects of life in North Korea, but how exactly do the ideological and substantive mathematical components interact in mathematics education there? What concrete form does this interaction take in actual everyday teaching practice? This article seeks to answer these questions based on interviews with former North Korean mathematics teachers and students who have found a refuge in South Korea. With their help, we attempt to analyze the everyday life of North Korean schools, by reconstructing their concrete features and the routines of North Korean mathematics education.
