When to Make the Sensory Social: Registering in Face‐to‐Face Openings

This article analyzes naturally occurring video‐recorded openings during which participants make the sensory social through the action of registering—calling joint attention to a selected, publicly perceivable referent so others shift their sensory attention to it. It examines sequence‐initial actions that register referents for which a participant is regarded as responsible. Findings demonstrate a systematic preference organization which observably guides when and how people initiate registering sequences sensitive to ownership of, and displayed stance toward, the target referent. Analysis shows how registering an owned referent achieves intersubjectivity and puts involved participants' face, affiliation, and social relationship on the line.

利益冲突、声誉激励与股价发现有效性

构建了分析师两期荐股模型,解析分析师和投资者的利益冲突、分析师类型不确定性和基本面的不对称信息三者相互作用并影响股价发现有效性的作用机制． 分析结果表明: 关联分析师方的“激励扭曲效应”源于其受利益相关方干扰后进行策略性荐股谋取私利; 独立分析师方的“声誉激励效应”源于其受远期市场上“身份识别”困扰等利他动机进行策略性荐股; 激励扭曲效应、声誉激励效应与价值投资者的策略性解读偏差共同导致分析师信息发现加工效率受损和股票市场有效性下降; 这一作用机制并不依赖于非策略性市场参与者假设; 常见的分级荐股方式有助于约束分析师的声誉激励并降低跨期效率损失． 这些结论为完善分析师薪酬考核机制、强化特定时点信息披露、分析师声誉市场培育、建立长效追踪制度和引入适当的长期责任承担制度提供了理论支撑．     

并购重组公告的短期财富效应研究——基于投资者有限注意的视角

基于投资者有限注意这一独特视角,实证研究了公司并购重组公告诱发的短期财富效应.研究结果表明:公告日前后,主并公司股票因不同投资者有限注意程度的不同而存在短期财富效应,且越临近公告日,短期财富效应越显著;同时,投资者自身注意力分散程度的周历分布特征会引起主并公司短期财富效应的周历变动,上市公司管理层也会据此对并购重组公告进行择机发布,导致财富效应周历变动更为显著;然而,投资者对上市公司特征关注的有限性,加剧了市场对并购重组的过度反应,提升了短期财富效应.因此,监管机构应当建立和完善重大信息披露机制,加强对投资者的教育和价值投资引导,而上市公司应当建立有效的内控制度,提高信息的透明度、真实性与及时性.     

任务转换范式下情绪注意偏向

相对于其他信息来说,情绪信息往往会引起情绪障碍患者更多的注意并具有一种认知加工上的优先权。在注意实验中,与中性刺激相比,具有情绪意义的刺激更能吸引注意或占用注意资源从而引起注意偏向。通过转换代价和任务规则一致性效应两个指标阐述了任务转换范式下情绪障碍患者的情绪信息注意偏向加工机制,并指出这两种指标分别代表了个体在注意偏向中的两个不同的认知控制加工,为情绪障碍患者的情绪调节提供必要的依据。文中最后还指出了ERPs、f MRI新技术是未来任务转换范式下研究情绪与注意关系的新方向。     

Attention and Executive Functions as Mediators of Attachment and Behavior Problems

The purpose of this study was to provide a more comprehensive understanding of the relation between early parent‐child interactions and subsequent behavior problems and how certain cognitive processes mediate this relation. Specifically, this study investigated whether attention, inhibition, and planning skills mediate the relation between attachment security and behavior problems. Data were collected as part of the National Institute of Child Health and Development‐Study of Early Child Care and Youth Development when children (N = 1004) were between 36 months and the third grade. Results from structural equation models indicated that sustained attention mediated the relation between disorganized attachment and social problems. Planning mediated the relation between disorganized attachment and subsequent thought problems, attention problems, and delinquent behavior. Avoidant, ambivalent, and disorganized attachment directly predicted several behavior problems. Implications for theory and future research are discussed.     

上市公司现金流操控动机选择研究

对现金流管理的研究是继盈余管理后兴起的管理层舞弊行为研究。在已有关于现金流操控阈值点研究的基础上,以2004年至2009年有分析师预测值的中国上市公司为样本,运用条件分布法,采用统计变量τ和z计算分布频率,并以分布频率直方图直观显示,分析上市公司在现金流量阈值点操控行为的动机选择。从统计结果和分布频率图可知,公司管理层对3个现金流阈值点确实存在不同选择。操控现金流微正的动机最强,即公司管理层更注重报告微正现金流量,其次是超越往年现金流量动机,而迎合分析师预测的动机最弱。研究还发现,管理层存在多重操控动机,即在控制已达到某一个阈值点之后,公司管理层更倾向达到另一个阈值点,存在好上加好的心理。     

西藏农牧民进城务工的价值引领与法律制度保障

西藏农牧民进城务工有增长之势.职业选择范围窄、劳务工资较低、生活素质较差等问题,折射出西藏农牧民工在劳动技能、职业素质、竞争能力等方面与当下市场经济要求存在一定距离.对此,既要引领农牧民工重视自身素质提高、增强竞争意识,自觉参与劳动技能教育与培训,更要敦促政府完善地方法规,从法律制度上保障各地县的农牧民接受劳动技能培训,建立提升农牧民参与现代化城市建设能力、提高农牧民物质生活的长效机制.     

社交网络、投资者关注与股价同步性

随着以微博、微信为代表的社交网络信息平台在中国的崛起，形成了新媒体时代下信息资讯生成与扩散的完整传播链条，深刻地影响着金融市场参与主体的学习认知习惯、投资决策理念、交易行为模式，最终影响不同金融资产的价格波动规律． 本文在新媒体时代情景下，以社交网络信息披露与传播平台为切入点，基于信息关注度、信赖度、更新频率等三层维度，构建社交网络微博信息质量指标体系，研究社交网络信息质量与股价同步性的内在关联关系． 研究表明: 微博信息质量与股价同步性有着显著的高度负向线性关联性，并且呈现出非线性 U 型关系． 即随着社交网络信息质量水平的提升，股价同步性逐渐降低到达最小值，而后又逐渐提高． 研究结论为证明上市公司社交网络微博平台对股价同步性有较强影响力，提供了中国金融市场的证据．     

国有企业CEO注意力对产品创新影响的研究

在探讨了CEO注意力、产品创新表现与企业绩效之间的关系的基础上,构建了有关理论模型,并通过问卷收集的方法对国有企业CEO进行了调研。研究结果表明,国有企业CEO对于外部的注意力普遍高于其对内部的注意力;外部注意力对于产品创新的技术表现和市场表现均有积极影响,内部注意力仅与产品创新的技术表现正向相关;产品创新的技术表现对于企业的财务绩效和非财务绩效均有积极影响,仅市场表现对企业非财务绩效有积极影响。     

Affective networks: how WeChat enhances Tencent’s digital business governance

An emerging body of literature has revealed that social media enhance digital business governance to facilitate Internet companies in generating profit throughout regulating the everyday lives of users. However, although existing debates are often contextualized in the West, little attention has been paid to China, where social media are widely used. To fill this knowledge gap, this article investigates the digital business governance practiced by Chinese Internet companies such as Tencent. Specifically, I employ an affective lens to analyze how WeChat, the most popular social media application launched by Tencent, allows this Internet company to influence users for its own business purposes. Chinese college students, which constitute a representative group of young people, were early adopters of WeChat, and they have led the trend of social media use in China. Based on a yearlong netnographic study of Chinese college students, the results reveal that the affective design of WeChat captured their attention and influenced their everyday practices. These results provide insight into how digital business governance operates in the Chinese context, in which authoritarianism and capitalism work closely together.
