科研合作网络及特性分析

为揭示超网络的某些特性,基于小世界模型和无标度模型,提出和建立两种超网络演化模型,并定义交叉度用于表征超网络节点之间合作关系,最后将超网络演化模型应用于中国原子能科学研究院核技术应用研究所科研合作网的实证分析。研究结果表明:不论是对于超网络理论模型还是实证分析,交叉度都能够优于以往的网络特性用于分析超网络不同层次之间节点的相互合作关系,为从理论上进一步深入分析超网络及其应用打下一定的基础。     

供应链中牛鞭效应的综合治理:基于协作视角的研究

从供应链协作的视角建立起一个牛鞭效应的综合治理框架,该框架包含了信息共享、决策同步、激励联盟、协作绩效体系以及共享的供应链过程五个相互联系的要素。其中信息共享、决策同步、激励联盟是缓解牛鞭效应的三个最基本的战略,这三个战略在协作绩效体系的指导下相互作用,最终创造了一个共享的、整合的供应链过程,从而可以有效地抑制牛鞭效应。

Widening equity and retaining efficiency: Considerations from the IBSA southern coalface

Access to higher education is a key challenge of the 21st century state. The link between higher education and personal and socio-economic development has intensified the need for ensuring that greater numbers of citizens have expanded access to and have been provided with quality higher education. The article seeks to explore how initiatives for increased access to higher education are experienced in India, Brazil and South Africa. As signatories to the IBSA declaration in the spirit of South–South cooperation, the three countries have publicly declared their commitment to enhance equity by, for example, widening access to higher education. We review the way in which the three countries have implemented key equity initiatives and draw lessons from their practice. Notions of ‘effectiveness’ and ‘efficiency’ are used to understand the extent to which each of the individual systems is responsive to the equity agenda. We find that while there have been notable attempts to implement the equity agenda in the quest for making their systems more ‘socially effective’. This is countervailed by a more pervasive ‘efficiency’ doctrine, underpinned by a market-driven economic paradigm. It is concluded that the innovative practices in each of the countries suggest important strides in the equity agenda but also that much still remains to be done. While the article represents a starting point for the much-vaunted South-South collaboration, tentative findings suggest that a more deliberately articulated policy framework characterized by greater inclusion of those previously excluded is necessary in each of the countries if significant and sustainable development is to be achieved.     

A framework for scaffolding students' assessment of the credibility of evidence

Assessing the credibility of evidence in complex, socio‐scientific problems is of paramount importance. However, there is little discussion in the science education literature on this topic and on how students can be supported in developing such skills. In this article, we describe an instructional design framework, which we call the Credibility Assessment Framework, to scaffold high school students' collaborative construction of evidence‐based decisions and their assessment of the credibility of evidence. The framework was employed for the design of a web‐based reflective inquiry environment on a socio‐scientific issue, and was enacted with 11th grade students. The article describes the components of the Credibility Assessment Framework and provides the details and results of an empirical study illustrating this framework in practice. The results are presented in the form of a case study of how 11th grade students investigated and evaluated scientific data relating to the cultivation of genetically modified plants. Multiple kinds of data were collected, including pre‐ and post‐tests of students' conceptual understanding and their skills in assessing the credibility of evidence, and videotapes of students' collaborative inquiry sessions. The analysis of the pre‐ and post‐tests on students' conceptual understanding of Biotechnology and their skills in assessing the credibility of evidence revealed statistically significant learning gains. Students' work in task‐related artifacts and the analysis of two groups' videotaped discussions showed that students became sensitive to credibility criteria, questioned the sources of data and correctly identified sources of low, moderate, and high credibility. Implications for designers and educators regarding the application of this framework are discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 48: 711–744, 2011
