新兴股票市场有效性及诚实性检验方法和实证分析

本文介绍了新兴股票市场有效性及诚实性检验方法，通过检验上市公司新发布的公告是否能引起股市交易量的增加和收益率的波动量增加来检验股票市场的有效性及是否存在内部交易的问题。如果在公告发布期间股市没有任何异常变动，市场可能是效率低下的或是存在内部交易。如果进一步分析能够证实在同一公司发布的针对不同持有群体的股票之间,如A股和B股或H股之间，存在滞后的引导关系，则可以基本判定股市存在内部交易。Utpa Bhattacharya已经对墨西哥的Bolsa Mexicana de Valores市场做过类似的研究并且发现该股票市场存在内部交易。本文对中国的股票市场进行研究。结果表明中国股市不存在明显的内部交易，但同时也发现中国股市的A股和B股市场之间的联动性较弱，中国股市有效性较差，尤其是B股市场对市场信息公告的反映很不明显。这些都在一定程度上反映了中国股市作为成长中的股市发展还不成熟，B股市场的发展尤其需要进一步努力。     

“管理哲学”何为

认为“管理哲学”学科的研究对象是知识形态的管理思想与理论,通过与“管理学原理”、“管理思想史”、“管理学方法论”等学科的对比,指出管理哲学在管理学体系中的定位应当是一门功能服务性的基础学科,其主要功能包括:揭示管理学知识与管理实践的因果链;考察管理学理论建构方法;关注管理学前沿领域问题,服务于管理学理论的发展与创新。     

Organisational sustainability modelling—An emerging service and analytics model for evaluating Cloud Computing adoption with two case studies

Cloud Computing is an emerging technology which promises to bring with it great benefits to all types of computing activities including business support. However, the full commitment to Cloud Computing necessary to gain the full benefit is a major project for any organisation, since it necessitates adoption of new business processes and attitudes to computing services in addition to the immediately obvious systems changes. Hence the evaluation of a Cloud Computing project needs to consider the balance of benefits and risks to the organisation in the full context of the environment in which it operates; it is not sufficient or appropriate to examine technical considerations alone.In this paper, we consider the application of CAPM, a well established approach used for the analysis of risks and benefits of commercial projects to Cloud adoption projects and propose a revised and improved technique, OSM. To support the validity of OSM, two full case studies are presented. In the first, we describe an application of the approach to the iSolutions Group at University of Southampton, which focuses on evaluations of Cloud Computing service improvement. We then illustrate the use of OSM for measuring learning satisfaction of two cohort groups at the University of Greenwich. The results confirm the advantages of using OSM. We conclude that OSM can analyse the risk and return status of Cloud Computing services and help organisations that adopt Cloud Computing to evaluate and review their Cloud Computing projects and services. OSM is an emerging service and analytics model supported by several case studies.     

情报交流研究的文本阐释学取向引论

With a review of the evolution of the theory of hermeneutics, this paper raises the problem of knowledge gap in information communication, and from the viewpoint of hermeneutics, analyzes its crux and key issues to be resolved. It further discusses the cognitive viewpoints in information studies, compares them with the text receiving theory and stresses the positions and roles of information users as the main part in information communication. Finally, it concludes that the inevitability and impoaance of using hermeneutics to study information communication deserves to be studied and practiced in depth and breadth.     

当代国际科学学主流学术群体及其代表人物

运用信息可视化技术等新兴科学计量学方法,对1995年至2004年国际科学学领域论文高被引频次前50名作者进行分析,绘制出科学学主流学术群体及其代表人物的知识图谱。该图谱形象地显示出这些高影响力作者在当代国际科学学主流领域,形成了科技管理与政策、情报学与信息检索、科学知识图谱与信息可视化、网络计量学、科学社会学与科学知识社会学、科学计量学理论与科研评价等前沿分支学科的6个学术群体。成为这些前沿学科与主流群体的代表人物。他们为开创或发展当代科学学主流分支学科做出了突出贡献,产生了巨大影响,值得我国科学学界密切关注。     

Urban youths’ hybrid positioning in science practices at the margin: a look inside a school–museum–scientist partnership project and an after-school science program

In what ways do urban youths’ hybridity constitute positioning and engagement in science-as-practice? In what ways are they “hybridizing” and hence surviving in a system that positions them as certain types of learners and within which they come to position themselves often as other than envisioned? To answer these questions, I draw from two ethnographic case studies, one a scientist–museum–school partnership initiative, and the other, an after-school science program for girls only, both serving poor, ethnically and linguistically diverse youth in Montreal, Canada. Through a study of the micro dialectics from the perspective of youth, I show what we can learn from examples of doing science in a formal and informal educational context supportive of marginalized science practices resembling in part, at least, science-as-practice. Through an integration of the findings with current discourses of relevance in science education such as funds of knowledge and youth centered, co-opted science, I contribute to the formulation of a global pedagogy of science education and in particular, what such may imply in the eyes of youth in French Canada.     

A re‐consideration of rates of ‘social mobility’ in Britain: or why research impact is not always a good thing

This paper re‐considers some of the evidence for low and declining social mobility in Britain, showing that one study based on a re‐analysis of cohort figures appears to have had an impact on policy‐makers out of all proportion to its scale and rigour. The study claimed to show that the income of parents and children were more closely related for sons born in 1970 than in 1958, and that therefore social mobility was declining. It also claimed to show that the incomes of fathers and sons were more closely related in Britain than in countries such as Norway. However, a reconsideration of the same results in this paper leads to very different conclusions. This example is considered in detail here to illustrate the point that it is not always a good thing for research to have influence. The most important and ethical challenge facing social research in education is to improve its quality rather than its impact.     

引证分析法作为科学评价的局限

引证研究存在着“质量”和“影响力”缺失的局限．通过对造成引证研究“质量”和“影响力”缺失因素的定量分析，进一步探讨了“质量”和“影响力”缺失的内在联系，并初步提出了弥补引证研究“质量”和“影响力”缺失的对策．     

定制化高等教育服务实施路径与实现机制:基于美国高校SDM的跨案例分析

定制化的高等教育服务模式能够激发学生探究学习的热情并突破传统专业培养和学科教育的束缚与限制,更加突出了学生的主体地位。在对克拉克大学、新泽西学院以及安提阿学院的自主专业设计项目进行分析时发现,定制化高等教育服务的实施路径包括生成阶段的目标定位,实施阶段的内容构建以及评价阶段的多维指标。此外,三所院校通过战略部署、资源配置、服务效能以及人才遴选等管理机制进行动态调整以确保实施路径的畅通有效。
