The Ethics of Meaningful Work: Types and Magnitude of Job-Related Harm and the Ethical Decision-Making Process

This research on the ethics of meaningful work examined how types of job-related harm (physical, economic, emotional, and cognitive) and their magnitude of consequences (MOC, low, high) influenced components of ethical decision-making (moral recognition, moral evaluations, and moral intentions). The research also investigated the moderating effects of individual differences (experience with carpal tunnel syndrome, experience with layoffs, ability to read others’ emotions, and intrinsic motivation orientation [IMO]) on the relation between the MOC and the ethical decision-making elements for each type of harm. Using a sample of 185 Chinese professionals, a between-subjects, fully crossed experimental scenario design revealed that physical and economic job-related harm were recognized as moral issues to a greater extent than cognitive or emotional harm. Second, physical job-related harm stimulated a higher level of moral evaluations than economic and cognitive harm. Third, individuals intended to act ethically when MOC was high versus low. Finally, experience with layoffs and IMO helped explain the relations between MOC and moral evaluations for economic and cognitive job-related harm, respectively. Implications for research and management are discussed.     

新冠肺炎疫情背景下政府规制网络谣言的范围与边界

在网络谣言的治理体系中政府规制扮演着重要的角色,尤其在新冠肺炎疫情的背景下,这种重要作用更加得以凸显.基于网络谣言已经逸出言论自由的范围和保障公共利益的需要,政府规制网络谣言具有正当性基础.但是,能够纳入政府规制的网络谣言在范围上并不能与传统的谣言相等同,前提须为具有可规范因素.通过梳理理论界及法律文本中关于网络谣言的认知与规定,本文发现网络谣言的范围一般包括虚假的、无事实根据的、非官方权威来源的和未经证实的信息.由于"非官方权威来源的信息"与"未经证实的信息"具有真伪不确定性,不宜直接纳入政府规制的网络谣言范围,而需要进一步廓清其法律边界.以这种不确定的信息作为规制的对象,政府适宜采取谦抑性态度,在符合法律保留原则、比例原则和正当程序原则的基础上,综合考量信息的发布主体、目的、受众范围、发布者与传播者的主观感受、社会危害程度等因素后审慎介入.     

How to inhibit a partner's strong and weak forms of opportunism: Impacts of network embeddedness and bilateral TSIs

This study investigates the moderating effects of a firm's network embeddedness and a partner's transactional specific investments (TSIs) on relationships between the firm's TSIs and its partner's strong- and weak-form opportunism, and compares the efficiency among these moderator variables. The regression results suggest that (1) a firm's TSIs are positively related to partner's opportunism when network embeddedness and the partner's TSIs are relatively low; but (2) a firm's TSIs are negatively related to partner's opportunism when network embeddedness and the partner's TSIs are relatively high. Furthermore (3) network embeddedness is more effective in inhibiting partner's weak-form opportunism than in inhibiting strong-form opportunism resulting from the firm's TSIs. Finally (4) with regard to the relationship between TSIs and weak-form opportunism, the negative moderating effect of network embeddedness is greater than the negative moderating effect of partner's TSIs. This study explains reasons why conflicting views exist about the relationship between TSIs and partner's opportunism, reveals the differences in the moderating effects of network embeddedness and partner's TSIs, and makes new contributions to both transaction cost theory and embeddedness literature. It also provides, for firms involved in TSIs in a buyer–supplier relationship, insightful managerial suggestions about ways to reduce their partner's varying forms of opportunism.     

玉林市存贷比运行特征、存在问题及对策建议——基于桂东四市比较

存贷款比例是银行业金融机构经营管理的重要指标之一,存贷比例过低不利于地方经济的发展。广西玉林市自2000年以来,存贷差逐年扩大,存贷比长期在低位徘徊,2013年存贷比在广西全区排最后一名。本文通过桂东四市（玉林市、梧州市、贺州市、贵港市）经济金融主要指标对比,分析玉林市银行业金融机构存贷比运行特征,揭示造成玉林市低存贷比的原因,提出提高存贷比的相关措施以及科学合理看待存贷比的建议。     

使用外语能降低经济决策偏差吗?来自实验室的证据

文章旨在检验使用外语对经济决策的两类核心问题，即不确定性（风险、模糊性）决策和跨期决策的偏差是否产生影响。两组实验被试被随机分到母语组和外语组，分别采用母语和外语完成一系列决策任务。实验结果发现使用外语能够显著降低与风险相关的决策偏差，但并不能降低与模糊性和跨期决策有关的决策偏差。具体而言，在与框架效应有关的风险决策任务中，使用外语显著减少了决策的框架效应；与母语组相比，在与小额金钱、大额金钱有关的风险决策问题中，外语组的反射效应消失了；外语组的阿莱行为也显著减少。在模糊性决策任务中，母语组与外语组在决策偏差上没有显著差异。在跨期决策任务中，使用外语对个体的焦虑程度没有显著的影响，但显著增加了双曲贴现偏好。这说明风险、模糊性和跨期决策所涉及的认知过程存在差异，使用外语对决策产生的作用具有复杂性。     

云南省农业科技创新资源配置效率及影响因素研究

[目的]为及时了解云南省农业科技创新的最新动态,充分合理地开发云南省农业科技资源,文章对2002—2016年云南省的农业科技创新资源配置进行研究。[方法]首先分析各个单项指标15年内的变化趋势,分析其对资源配置的影响和作用。再运用DEA模型分析法,将2002—2016年的每个年份作为一个决策单元进行处理,对云南省农业科技创新资源配置效率进行分析。[结果] 2002—2016年云南省农业科技创新资源配置的综合效率为0. 984,并且呈现出不稳定的波动,在2004和2009—2012年出现了配置效率降低的情况。总体来看,资源配置的综合效率大体上是接近于1的水平。处于DEA有效的年份为2002—2003年,2005—2008及2013—2016,属于规模报酬不变的阶段; 2004年属于弱DEA有效阶段,规模报酬则处于上升阶段;处于非DEA有效的有2004年、2009—2012年。[结论]云南省农业科技创新资源的配置效率整体水平处于较高的状态,综合效率值总体上接近于1。有个别年份出现了较小范围的波动,可能与总播种面积的变化有关。综合来看,云南省农业科技创新资源在技术投入、人力资源和农业资金投入逐年的增加,使资源配置效率能够保持在较高的水平,并在出现下降后迅速恢复。     

新型个人信息保护体系构建研究

大数据时代,传统的以“信息收集”规制为着力点的个人信息保护出现适法性困境,以“知情同意”为框架的机理失灵,个人信息的利用对象从直接个人信息逐渐向间接个人信息过渡,其财产价值凸显,新型个人信息财产权呼之欲出。立法应顺应数字经济的发展,构建合理新型个人信息体系。具体而言:纵向层面,以“宽进+删除权”为具体保护策略;横向层面,在信息主体和信息产业者之间合理配置权利,即信息主体享有个人信息权和个人信息财产权,信息产业者享有信息资产权。     

Drivers of research impact: evidence from the top three finance journals

We study the characteristics of all published papers in the top three finance journals (JF, JFE and RFS), and how these paper characteristics affect the number of citations in Google Scholar and the Web of Science database. First, we find the characteristics in the universalist perspective remain constant while the characteristics in the constructivist and presentation perspectives increase over time. Second, some characteristics are significantly different between the high-impact and the low-impact papers. Third, paper quality, research method, journal placement and paper age are the most important drivers. Last, different drivers play different roles in different journals.     

粤东西北与珠三角物流产业技术效率比较

运用DEA效率测度方法,通过对2013-2017年粤东西北与珠三角区域物流产业技术效率的对比研究,探索推动广东省区域物流协调发展的路径。结果显示:对比珠三角区域,粤东西北区域物流产业技术效率与珠三角区域存在较大差距,尤其是粤东与粤西地区,粤东区域物流产业技术效率值仅为0.4,粤西区域物流产业技术效率值为0.81,均远低于珠三角区域物流产业技术效率值0.94。纯技术效率低下是制约粤东西北地区物流产业技术效率提升的主要因素,应加强物流产业信息技术应用,推进物流技术装备现代化,提高技术创新能力水平。
