机会网络研究进展

随着移动通信设备的普及,无线网络逐渐成为网络领域的热点研究内容。由于无线环境通信具有大传输时延、间歇性连接以及高误码率等特征,传统的面向连接的网络形式面临了巨大的挑战。机会网络(Opportunistic Network)的出现,为组建无线网络提供了一种新模式。机会网络采用"存储—携带—转发"的路由机制,信息传递通过节点移动带来的相遇机会实现,从而能够为缺乏持续端到端连接的网络提供通信服务。系统地介绍了机会网络的概念、结构以及节点移动模型、路由机制、拥塞控制等方面的研究进展,并对其未来的研究方向进行了展望。     

大数据在基础教育管理与决策中的应用研究

进入大数据时代后,基础教育管理和运行迎来了更多的发展机遇,基于大数据的预测、分析将逐步融入基础教育管理和决策中。大数据技术和思维将影响基础教育管理与决策的各个环节,影响基础教育发展规划,改变基础教育教学评价体系,甚至在基础教育教学思维中产生深远的影响。基础教育管理工作者应主动研究和思考,以积极的态度迎接大数据时代的来临。     

用于异质用户出行管理的可交易许可证研究

针对公共交通与私家车出行方式并行的双模式交通系统,在考虑不同用户的时间价值情况下,通过引进可交易的道路许可证政策,建立了均衡出行交通模型.研究发现,许可证政策将拥挤产生的交通成本内部化,在缓解交通拥堵的同时,通过经济手段,降低了系统总成本.进一步地,本文证明如果汽车比公交快,那么时间价值较高的人会选择私家车出行;反之,如果公交比汽车快,时间价值相对较高的有车族会选择公交出行.通过与OD收费进行比较,我们得到在收费为正的情况下,许可证政策可以得到与基于OD收费相同的效果.最后,算例结果表明,许可证政策使得部分人选择公交出行的成本更低,达到鼓励公交出行的目的;甚至在许可证发放数量少于临界数量的情况下,选择公交出行的人会获得正收益.     

基于组织支持感知的事业单位人力资源管理研究

针对我国事业单位人力资源管理改革面临着管理者角色重新定位、人才流动性加快、员工忠诚度降低等的挑战,本文从组织支持感知角度,构建事业单位人力资源管理模型。通过结构方程研究发现,我国事业单位员工的薪酬满意度、对LMX的理解、对于单位职业发展机会的理解、员工认为单位的工作家庭支持以及工作绩效与POS水平正相关;与离职意愿负相关。结论有利于事业单位制定正确的人力资源管理战略。     

Scientists and their cultural heritage: Knowledge,politics and ambivalent relationships

For many years, scientific heritage has received attention from multiple actors from different spheres of activity—archives, museums, scientific institutions. Beyond the heterogeneity revealed when examining the place of scientific heritage in different places, an authentic patrimonial configuration emerges and takes the form of a nebula of claims and of accomplishments that result, in some cases, in institutional and political recognition at the national level, in various country all around the world. At the international level, the creation of the international committee dedicated to University Museums and Collections (UMAC) within the International Council of Museums (ICOM) certainly testified from this raising interest in academic heritage and the existence of a specific community concern with it.This article presents numerous initiatives for the preservation of scientific heritage in France, with the goal of analysing the relationship scientists have with their heritage. We argue that scientific communities have a special relationship with heritage, which is characterized by a number of ambiguities. We show that such ambivalences allow analysis of identity, discipline, professional, and social issues operative in defining heritage and being redefined by heritage. To explore these dimensions, we have chosen to present three different case studies. The first traces the institutional uses of heritage by a scientific institution, the Commissariat à l’énergie atomique (CEA), through the transformation of the first French atomic reactor (ZOE) into a museum. The second example describes the initiatives of French astronomers from the mid-1990s to construct a national programme for the protection of astronomy heritage. Lastly, we recount the case of universities, with the example of the Université de Strasbourg.     

On the Difficulty of Measuring Forecasting Skill in Financial Markets

The use of correlation between forecasts and actual returns is commonplace in the literature, often used as a measurement of investors' skill. A prominent application of this is the concept of the information coefficient (IC). Not only can the IC be used as a tool to rate analysts and fund managers but it also represents an important parameter in the asset allocation and portfolio construction process. Nevertheless, a theoretical understanding of it has typically been limited to the partial equilibrium context where the investing activities of each agent have no effect on other market participants. In this paper we show that this can be an undesirable oversimplification and we demonstrate plausible circumstances in which conventional empirical measurements of IC can be highly misleading. We suggest that improved understanding of IC in a general equilibrium setting can lead to refined portfolio decision making ex ante and more informative analysis of performance ex post.
