借壳上市对我国沪深两市有效性影响研究

取2010-2013年沪深综指和2008-2013年间借壳上市公司的数据,基于单位根检验和事件分析法,用经GARCH改进的市场模型对我国沪深两市的有效性进行了实证研究.结果表明,我国沪深两市已达弱式有效,但还未达到半强式有效,上海股票市场有效性比深圳股票市场强,深圳股票市场投机行为比较明显.股价的提前反应从侧面反映了我国证券市场仍然不成熟,内幕消息提前泄露的可能性较大,对此应不断完善借壳上市过程中相关的法律法规;加大对公司借壳上市的监管力度;规范股票市场的各项机制,改进股票市场的有效性.     

群体性事件的生成土壤与理性应对

对群体性事件做清晰的概念界定,并基于现有文献对类型归属做明确的划分。深刻阐述社会转型的冲突与调适、刚性稳定的利益悖论、公共危机治理的处置失当、社会心理失衡的非理性应对是引发群体性事件的深层诱因,以资从制度规范和实践应对的维度,提出建构和完善群体性事件处置的政策体系,解释了强化群体性事件处置的操控性技术的可行性,并借鉴国外群体性事件处置的理论技巧,提出坚持"现场第一"原则、"处境化"思维、警察权的配制与使用等操作化建议,以此使各地应对群体性事件的有效经验制度化,实现国家长治久安。

Do rating agencies’ decisions impact stock risks? Evidence from European markets

This article analyses the effect of rating agencies’ decisions on stock risks for European issuers concerning five kinds of events. Our approach is an extension of dummy variable regression event study methodology, using a GARCH(1,1) estimation to capture simultaneously the impact on both systematic and specific stock risks. This new methodology allows us to obtain both global results by categories of rating decisions and individual results, event by event. We document, globally, a positive impact of upgrading on systematic risk, a negative impact of rating confirmation on specific risk, and no significant impact in all other cases. Regarding event-by-event results, the proportion of rating actions exhibiting a significant effect on risk is almost always observed between 20% and 30%. The weak evidence of a global effect on systematic risk may be due to the lack of informational content of the rating decisions on the stocks’ risk, or the existence of rebalancing effects between systematic and idiosyncratic risks. Furthermore, it should be noticed that the decline in volatility in case of a rating affirmed is an insight of the certification role played by the agencies.     

Application of early risk detection concepts and methods to environmental health. A German feasibility study

Early risk detection is essential for being able to address the most important environmental health risk‐topics in a persistent and prospective manner. In support of the action programme “Environment and Health” (APUG) of the German Federal Ministry of Health and Social Security (BMGS) and the Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU) which recommended that a detection and evaluation system for the timely recognition of emerging risk problems be developed, a qualitative feasibility study was commissioned. The results of this study are presented here and support the development of an early risk detection system based on the insights gained from the investigation of case studies and the differentiation and presentation of a risk typology, methods, tools, and suggested organizational processes.

The study has shown that early risk detection includes the identification, characterization, evaluation and dissemination of information on possible risks as well as the circumstances of appearance and distribution. The goal is the recognition of possible risks in order for risk management to be able to introduce swift and appropriate measures. Consequently, it can also serve as an instrument towards further development of a balanced and structured implementation of the precautionary principle in the environmental health policy.     

Organizational culture evolution in temporary organizations: The case of the 2010 Olympic Winter Games

We examine organizational culture evolution within a temporary organization, specifically the 2010 Olympic Winter Games organizing committee, by exploring aspects of the work environment. Analysis of organizational artifacts, ethnographic field‐notes, and member‐checking demonstrated that liminal spaces facilitated socialization and cultural crystallization, which in turn assisted members' performance. Organizational structure, socialization, and cultural evolution were parallel processes that impacted each other. The concept of time (i.e., velocity) had a direct influence on subculture crystallization. The paper further integrates stakeholder/client interactions and draws on the role of leadership and cultural infusion mechanisms to demonstrate how culture evolves in temporary organizations.

Individual and Institutional Concentration of Leisure Research in North America

The purpose of this article is to identify key characteristics of the community of leisure scholars in North America and to use patterns derived from data about publication activity as a platform for discussing the nature and implications of concentration in leisure research at the individual and institutional levels. The study uses cluster analysis to detect patterns of research and publication activity among 1785 people who were associated with leisure research in North America in the 1990s, concentrating on the slightly smaller number of people (1631) whose names were listed as authors on at least one publication in all editions of 6 research journals and 14 conference proceedings from 1990 to 1999 inclusive. The results demonstrate that leisure research in North America is concentrated at both the individual scholar and institutional levels. For example, at the individual level, less than one-fifth of authors accounted for more than two-thirds of journal articles and conference papers. The implications of these findings are discussed with reference to issues such as the critical mass of scholars and problems of disciplinary isolation detected by previous researchers.     

电子竞技运动在南宁的发展现状分析
