Effects of issue ownership and issue obtrusiveness on corporate reputation at two Korean corporations

This study attempts to identify the effects of issue ownership of a corporation on its reputation, and the moderating effect of issue obtrusiveness. Two representative Korean corporations (Hyundai and SK) were selected and their reputations were measured. It was shown that a corporation, which owns issues that were perceived as important by publics, has a higher corporate reputation. There was no moderating effect of issue obtrusiveness on the relationship between issue ownership and corporate reputation; however, there was a possibility of issue obtrusiveness as an independent variable. Implication for public relations research and practice was discussed.     

集体土地征收中“公共利益”被泛化的根源与化解路径探析

集体土地所有权产生的背景基础与社会功能定位是导致土地征收"公共利益"被泛化的深层原因;现行法律规定的内在冲突是导致土地征收"公共利益"被泛化的法律根源;现行财税体制及征地制度与供地制度之间的巨大利益空间是导致土地征收"公共利益"被泛化的现实根源;社会性质和传统经济体制是导致土地征收"公共利益"被泛化的体制根源;政府对土地一级市场的垄断是导致土地征收"公共利益"被泛化的直接原因;私权意识淡薄是影响土地征收范围的深层思想根源。集体土地征收中"公共利益"泛化的化解路径包括:长期目标和近期目标相结合,逐步缩小土地的征收范围;挖掘存量建设用地潜力,切实提高土地集约利用水平;建立合理的征地补偿和利益分享机制,有效限制国家征地权。

统筹协调农业结构调整保证农民持续增收

统筹协调农业结构调整对农业可持续发展、提高人民生活水平具有现实必要性和重要性,资源环境、国内外市场及政策导向等影响农业结构调整,同时制约农民的增收。农业的产业结构、区域结构、组织结构、技术结构、社会结构及投融资结构调整是保证农民持续增收的主要途径。     

四维忠诚管理及其应用

随着市场竞争的加剧,企业正面临着顾客、员工、投资者流动和流失的危险,加强忠诚管理成为企业管理的主要课题。在对三维忠诚管理理论的认识和理解的基础上,加入企业因素,提出了四维忠诚管理的概念。系统分析了顾客、员工、投资者和企业四者之间相互依存、相互制约、共同发展的关系,提出由四者组成“生态圈”的概念。给出了顾客忠诚、员工忠诚和投资者忠诚在企业管理中应用的若干对策,建立了四维忠诚管理模型即忠诚体系。     

Are state mindfulness and state work engagement related during the workday?

Given the growing interest in mindfulness in the workplace and the established importance of work engagement for work-related health and well-being, we explore the relationships between these 2 positive psychological states as they vary naturalistically over the workday. Utilising data from 3 measurement occasions per day (before work, mid-workday, and end-workday), we track natural variations in state mindfulness and state work engagement to create a fine-grained picture about their reciprocal relationships within the workday. A sample of 94 university employees completed multiple diary entries per day, for 10 working days. Data were analysed using multilevel structural equation modelling in MPlus, testing within-person pathways between mindfulness and work engagement across the day. Although state work engagement was a predictor of subsequent state mindfulness, state mindfulness did not predict subsequent state work engagement when controlling for earlier within-day work engagement. Overall, the within-day associations between mindfulness and work engagement were weak. We note the high within-day stabilities of state mindfulness and state work engagement, and discuss whether job and personal resources as well as task features might be moderators in the relationships between these constructs.     

国际油价、美国经济不确定性和中国股市的波动溢出效应研究

2008年金融危机以来的全球股市震荡,油价波动剧烈和经济的不确定性使得研究不同市场间的风险传导效应具有重要的意义。在综合评价现有研究的缺陷和既有改进方法的情况后,本文借鉴Diebold and Yilmaz （2012）的研究方法探索国际原油价格、美国经济不确定性和中国股市的波动溢出效应。本文选取1986年1月到2016年12月原油价格、美国经济不确定性指数和中国股票价格的月度数据,分别研究了静态波动溢出指数,动态波动溢出指数并做出了非线性检验。实证结果表明：变量国际油价解释了大部分的波动。方向性溢出指数是双向的和非对称的。在整个样本阶段系统的波动主要来自其他变量的冲击,变量国际油价的溢出效应占比重较大。变量国际油价、美国经济不确定性和中国股价对其他变量的波动溢出都存在非线性效应,前两者的正向变量的溢出效应较大,负向变量的溢出效应较小;后者的正向变量的溢出效应较小,负向变量的溢出效应较大。     

基于动态无标度网络的信息策略与羊群行为演化研究

传统的人工股票市场效率不高,对投资者的异质性假设缺乏经济学含义,更没有考虑市场中广泛存在的羊群行为的影响。本文以国外期权市场异质信息交易者模型为基础,结合互联网金融特点在传统人工股票市场中引入异质信息策略与动态无标度人际关系网络刻画的羊群行为构建出新的人工股市模型,进行投资者的信息策略与羊群行为演化研究,对比分析不同机制的引入所带来的影响,揭示动态关系网络环境下信息策略演化结果。研究发现：一方面,信息策略演化机制的引入加快了市场均衡速率并提高了市场效率,同时也大大降低了投资者财富水平并拉大了财富差距;信息策略与羊群行为的演化并不会导致投资者完全向内幕信息交易者聚集,高、低信息档次投资者明显居多且其他信息档次投资者仍然存在。另一方面,动态关系网络下羊群行为的引入增强了投资者的被传染程度,并进一步缩小了财富差距且显著提高了内幕信息的扩散质量与效率。所以,互联网关系网络环境下高、低信息档次投资者占据相对优势,但其他信息档次投资者并不会被挤出市场;监管部门在努力寻求高市场效率的同时,也应在投资者财富与社会总财富等方面进行适当权衡。     

Nonparametric predictive inference for stock returns

In finance, inferences about future asset returns are typically quantified with the use of parametric distributions and single-valued probabilities. It is attractive to use less restrictive inferential methods, including nonparametric methods which do not require distributional assumptions about variables, and imprecise probability methods which generalize the classical concept of probability to set-valued quantities. Main attractions include the flexibility of the inferences to adapt to the available data and that the level of imprecision in inferences can reflect the amount of data on which these are based. This paper introduces nonparametric predictive inference (NPI) for stock returns. NPI is a statistical approach based on few assumptions, with inferences strongly based on data and with uncertainty quantified via lower and upper probabilities. NPI is presented for inference about future stock returns, as a measure for risk and uncertainty, and for pairwise comparison of two stocks based on their future aggregate returns. The proposed NPI methods are illustrated using historical stock market data.     

Acceptance sampling plans based on truncated life tests for weighted exponential distribution

Gupta and Kundu proposed a new class of weighted exponential distributions using the idea of Azzalini. In this article, we develop an acceptance sampling plan for the weighted exponential distribution under a truncated life test. For various acceptance numbers, consumer’s confidence levels and values of the ratio of the experimental time to the specified mean lifetime, the minimum sample size necessary to ensure a certain mean lifetime are obtained. The operating characteristic function values and the associated producer’s risks are also presented. A numerical example is provided to illustrate the acceptance sampling plan.
