媒体在公司治理中的作用述评

美国相继发生的安然、世通、施乐等财务舞弊案件,让媒体能否发挥公司治理功能这一主题受到社会各界的高度关注。从现有的经验证据来看,媒体通过声誉机制和信息媒介机制,提升了西方资本市场上上市公司的治理水平。我国对该问题的研究基本处在兴起阶段。本文综述和评析了国外关于媒体与公司治理关系的最新进展,通过建立媒体参与公司治理的一般理论分析框架,为我国学者从事该领域的深入研究提供思路与启示。     

应对不确定性：危机传播管理的博弈与创新

现代危机具有的不确定性让危机传播面临更大的挑战,不确定性越大,危机就越来越难以被预测,社会管理者就失去了观测和制定传播计划的主要依据,这令作为公共危机传播管理者的政府经常面临两难选择。危机的不确定性很大一部分来源于媒体融合环境的不确定性,这使现代危机传播的整个过程也变得不确定。政府作为现代危机传播者,必须对危机传播过程中的不确定性有充分的认识,在危机传播和应对的过程中灵活博弈,把握传播机会,创新传播方法。     

Who Cares about Auditor Reputation?*

I provide evidence on the demand for auditor reputation by examining the defections of Arthur Andersen LLP's clients following the accounting scandals and criminal conviction marring the auditor's reputation in 2002. About 95 percent of clients in my sample did not switch auditors until after Andersen was indicted for criminal misconduct regarding its failed audit of Enron Corp. I test whether the timing of client defections and the choice of a new auditor are consistent with managers' incentives to mitigate potentially costly information and agency problems. I find that clients defected sooner, mostly to another Big 5 auditor, if they were more visible in the capital markets; such clients attracted more analysts and press coverage, had larger institutional ownership and share turnover, and raised more cash in recent security issues. However, my proxies for agency conflicts — managerial ownership and financial leverage — are not associated with the timing of defections or the choice of new auditor. Overall, my study suggests that firms more visible in the capital markets tend to be more concerned about engaging highly reputable auditors, consistent with such firms trying to build and preserve their own reputations for credible financial reporting.     

Social impacts of new communications media the Japanese experience

The author maps the emergence of new communications media in Japan and discerns major trends. He classifies their major social roles as information request, social participation, and enhanced dialogue. Social experiments with such media are necessary to guage and improve their acceptability to their intended users. Furthermore, significant impacts on social activities are anticipated when a new medium gains acceptance.     

试析媒介融合背景下二维码对广告业的影响

在媒介融合的时代背景下,手机广告作为一种新兴的广告形式日益引起人们广泛关注。相对于传统媒体广告,二维码广告具有受众卷入程度高、传播内容立体化、较强的伴随性和互动性等特点。本文从精确测定广告效果、精准定位消费者、拓宽广告营销渠道、改变广告传播方式等四方面探讨了二维码对广告业的影响,并预测随着互联网的发展、智能手机的普及、3G服务的渗透,手机直接访问互联网将越来越便利,二维码这一新型广告形式将大有作为。     

Information flow between prediction markets,polls and media: Evidence from the 2008 presidential primaries

Are the forecast errors of election-eve polls themselves forecastable? We present evidence from the 2008 Democratic Party nomination race between Barack Obama and Hillary Clinton showing that the answer is yes. Both cross-sectional and time series evidence suggests that market prices contain information about election outcomes that polls taken shortly before the contests do not. Conversely, election surprises relative to polls too Granger cause subsequent price movements. We then investigate whether the additional information in prices could come from the media coverage of these campaigns, and uncover a set of complex relationships between pollster’s surprise, price movements, and various aspects of media coverage. Prices anticipate the balance and content of media coverage, but not the volume. On the other hand, it is the volume of media coverage, not the balance or content, that anticipates the surprise element in election outcomes. Moreover, Granger causality between prices and election surprises barely changes after controlling for media coverage, and causality from media volume to surprises persists too after controlling for price movements. Taken together, the results suggest that both prices and the volume of media coverage contain independent election-relevant information that is not captured in polls.     

如何解决传媒人才短缺难题

当前,传媒业的激烈竞争实质上是人才的竞争。人才是传媒成败的“牛耳”。解决人才短缺问题是着眼向外,还是着手向内？不排除向外,但主要应下力激活内部人力资源。这样做,可以防止造成新的人才浪费,可以避免爆发恶性人才大战,从而有利于传媒业的和谐发展。那种过份“引进”、忽视“挖潜”的做法是不可取的。     

空中庭院与半围合式住宅感知密度的关联性研究——以广州万科峯境为例

在半围合式城市住宅中,感知密度是居住体验的重要环节。空中庭院能够缓解高密度环境中的拥挤感,优化其空间形态,是改善环境感知的建构基础。使用虚拟现实技术进行密度感知实验,能探讨与空中庭院形态相关的视觉因素——可视性和绿视率对环境感知密度的影响。将广州万科峯境作为原型建立15组以可视性与绿视率为变量的实验模型,通过采集受试者对不同环境感知密度的主观评价,反映实验样本的空间特征,进而分析主观评价与客观量化之间的关联机制。分析结果表明：半围合式城市住宅空中庭院的可视性与绿视率是影响居住环境感知密度的重要因素;呈线状分布的、具有视觉层次性的空中庭院更受大众青睐。
