Communicating about infectious disease threats: Insights from public health information officers

The public health communication challenges that arise in times of infectious disease threats (IDTs) were examined using the Risk Amplification through Media Spread (RAMS) Framework and in-depth phone interviews with 40 national, state, and local public health information officers (PIOs). Interviewees shared their experiences and insights related to how IDTs are communicated to the public, including the different types of traditional and social media used, how they develop and assess IDT messages, and their perceptions regarding the IDT risk amplification process. Theoretical and practical implications for health public relations and public health communication are discussed.     

资源下乡、私人关系与村庄秩序——以T村绿化工程承包权竞争为例

从村庄内部的视角,以T村村民与村支书竞争村庄绿化工程的承包权为案例,通过对乡村公共资源分配中的“自己人/外人”区隔,考察当前“项目制”资源下乡背景下,乡村精英在公共项目竞标中的行动逻辑及其对村庄社会秩序的影响。研究发现:由于对乡村干部缺乏有效的权力约束,当前农村公共资源的分配过程中呈现出“私人关系化”的明显倾向;公共资源的事务竞争常常发展成为不可调和的人事斗争,最终往往为打败对方双方都采取了非理性的争夺手段;这种只问结果不问手段的行为逻辑引发了一系列矛盾纠纷,导致村庄一步步走向失序。构建合理而有效的基层权力约束及其公共资源分配机制,是村庄承接下乡资源并且避免意外社会后果的基础条件。     

Insider Trading,Stochastic Liquidity,and Equilibrium Prices

We extend Kyle's (1985) model of insider trading to the case where noise trading volatility follows a general stochastic process. We determine conditions under which, in equilibrium, price impact and price volatility are both stochastic, driven by shocks to uninformed volume even though the fundamental value is constant. The volatility of price volatility appears ‘excessive’ because insiders choose to trade more aggressively (and thus more information is revealed) when uninformed volume is higher and price impact is lower. This generates a positive relation between price volatility and trading volume, giving rise to an endogenous subordinate stochastic process for prices.     

Transforming the social order: The role of the university in social change

The contemporary multicultural and secular university in the United States is experiencing an array of value transitions as well as ideological contradictions. The present dilemmas and challenges confronting the academy appear to emanate from the preoccupation with new schools of explanation and interpretation and from arbitrarily defined appropriate speech. In the social sciences and in the humanities, value neutrality and traditional constructs are viewed as strategies for concealing and promoting anachronistic standards of conduct. Faculty interviewed express concern and skepticism about the direction and future of the American university in a postindustrial and a postmodernistic era. Many perceive the university as not assuming a leading role in constructive social change. This results from its absorption with political symbols and selectively perceived meanings of varied cultural interests. Some faculty sense a major transformation in the way the university and its culture are produced and arranged. The social sciences and humanities have the potential for coping with the current paradoxes.This paper is a revision of the presidential address delivered in Boston at the 1993 annual meeting of the Eastern Sociological Society.

我国证券投资基金业绩评价的实证研究

实证研究结果表明:经过风险调整后,大部分基金的业绩优于市场基准组合;利用T-M,H-M模型分析,可以看到基金经理具有一定的证券选择能力,但并不显著;利用TM-FF3模型和HM-FF3模型分析,可得出基金经理没有证券选择能力的结论。无论采用上述哪种模型,均可发现基金经理的市场把握能力较差,但同样不显著。经综合分析,基金经理的证券选择能力是依据对市场公共信息的分析得到的,并没有证据表明基金经理凭借内幕消息而获得超额收益。     

我国企业年金运行轨迹的偏移与矫正--一个企业视角的分析

在我国,企业年金的运行轨迹发生了偏移,成为变相发放现金福利的工具甚至洗钱的手段。透过企业制度影响企业年金的视角,表明举办企业所存在的内部人控制问题和短期行为严重是造成企业年金运行轨迹偏移的主要原因。根本的矫正措施应当是完善产权制度,健全企业文化,并且对企业年金进行有效的制度安排。     

中美内幕交易监管机制对比研究

由于信息的不对称以及股市买卖内在机制所导致的内幕交易的存在,使得在一小部分交易者获得超额利润的同时,大多数中小投资者的利益受到了严重的损害。在世界保护广大中小投资者的大背景下,国际理论界已经对衡量内幕交易和监管体制进行了大量研究,并建立了相关的理论模型。在对中美法律体制和监管机制进行系统对比的基础上,应吸取国外的先进经验,弥补法律制定、实施以及制度设置上存在的不足,建立有效的监管机制以限制内幕交易的进行。

通过对华夏建通公司诉严某短线交易案的分析,表明我国《证券法》第47条在立法层面上存在一定问题。我国应通过域外先进立法例的学习和借鉴,进一步完善短线交易归入权制度的义务主体、认定标准、计算方法、豁免情形及配套措施,如此方能在提升制度正当性的同时更有效地发挥“事先阻吓”的功能。     

组织支持、地位认知与员工创新: 雇佣多样性视角

本研究基于社会比较与社会交换理论探讨了雇佣身份多样性和内部人地位认知在组织支持与员工创新行为间的作用． 在对256 套配对问卷进行统计分析的基础上,研究结果发现,内部人地位认知中介组织支持与员工创新行为间的关系; 雇佣身份多样性不仅负向调节组织支持与内部人地位认知的关系,还负向调节组织支持感知与员工创新行为间的关系． 研究结果对于“为何更多的组织支持无法驱动更多员工创新行为”等问题提供了一个新的解释,也使组织真正清楚“什么样的制度设计及如何提供组织支持可正向推动员工创新行为,提高组织有效性”．
