Changing Corporate Governance in Response to Negative Media Reports

We study how organizations change their corporate governance in response to negative publicity in the media. We build on insights from the literature on interpersonal trust to theorize how organizations respond to different types of trust‐damaging information. We suggest that organizations are likely to replace key individuals involved in the corporate governance process when trust‐damaging information provides evidence of low integrity. In contrast, organizations are likely to make changes in how the governance process is organized when trust‐damaging information provides evidence of low benevolence. We test our hypotheses by using data on publicly traded Korean firms from 2006 to 2013. Our results provide general support for our argument about corporate governance changes that organizations initiate in response to different types of trust‐damaging information. We also explore how foreign ownership and state ownership moderate organizational responses to trust‐damaging information.     

Approximations for Estimating Change in Life Expectancy Attributable to Air Pollution in Relation to Multiple Causes of Death Using a Cause Modified Life Table

There is considerable debate as to the most appropriate metric for characterizing the mortality impacts of air pollution. Life expectancy has been advocated as an informative measure. Although the life‐table calculus is relatively straightforward, it becomes increasingly cumbersome when repeated over large numbers of geographic areas and for multiple causes of death. Two simplifying assumptions were evaluated: linearity of the relation between excess rate ratio and change in life expectancy, and additivity of cause‐specific life‐table calculations. We employed excess rate ratios linking PM_2.5 and mortality from cerebrovascular disease, chronic obstructive pulmonary disease, ischemic heart disease, and lung cancer derived from a meta‐analysis of worldwide cohort studies. As a sensitivity analysis, we employed an integrated exposure response function based on the observed risk of PM_2.5 over a wide range of concentrations from ambient exposure, indoor exposure, second‐hand smoke, and personal smoking. Impacts were estimated in relation to a change in PM_2.5 from 19.5 μg/m³ estimated for Toronto to an estimated natural background concentration of 1.8 μg/m³. Estimated changes in life expectancy varied linearly with excess rate ratios, but at higher values the relationship was more accurately represented as a nonlinear function. Changes in life expectancy attributed to specific causes of death were additive with maximum error of 10%. Results were sensitive to assumptions about the air pollution concentration below which effects on mortality were not quantified. We have demonstrated valid approximations comprising expression of change in life expectancy as a function of excess mortality and summation across multiple causes of death.     

Disentangling the role of knowledge similarity on the choice of alliance structure

This paper examines the effect of knowledge similarity on the choice of alliance structure in the biotechnology industry. Knowledge similarity between two alliance partners has implications for both integrating and protecting knowledge. Alliance partners have incentives to select the alliance structure that maximizes efficiency in integrating knowledge. Likewise, alliance partners have incentives to select the alliance structure that protects appropriable knowledge. We draw upon the arguments of the knowledge accessing theory and causal ambiguity perspectives as well as the transaction cost economics perspective to predict the role of knowledge similarity on the choice of alliance structure. We empirically test the role of technological overlap and technological component on alliance structures-equity based versus non-equity based. The empirical results show that as technological overlap increases and technological component exists, the probability of equity based alliance structure increases.     

朝鲜对中国儒学的接受——以栗谷李珥的《圣学辑要》为中心

高丽末期,从中国传入的朱子学成为在朝鲜占统治地位的意识形态,对朝鲜历史产生了极大的影响。特别是可称为帝王学标本的《大学》在以多样形态发展的过程中,被朝鲜的政治指导者视为教材。朝鲜时代的学者栗谷撰述的圣学教科书《圣学辑要》对《大学》进行再解释和学问上的发展。《圣学辑要》以《大学》的"三纲领八条目"为基础,分为"修己"、"正家"和"为政",包含更广泛的内容。《大学》所体现的单纯层次的修己治人,被发展为非常具体的政治和人生的实践指南。尤其是把具有模糊意义的儒教理念表现为实际人生的现实,使朝鲜儒教得以体系化。这就体现了所谓以"正"为核心的政治,追求持续性人生的矫正教育。     

The Impact of Contracts and Competition on Upstream Innovation in a Supply Chain

We consider a supply chain with an upstream supplier who invests in innovation and a downstream manufacturer who sells to consumers. We study the impact of supply chain contracts with endogenous upstream innovation, focusing on three different contract scenarios: (i) a wholesale price contract, (ii) a quality‐dependent wholesale price contract, and (iii) a revenue‐sharing contract. We confirm that the revenue‐sharing contract can coordinate supply chain decisions including the innovation investment, whereas the other two contracts may result in underinvestment in innovation. However, the downstream manufacturer does not always prefer the revenue‐sharing contract; the manufacturer's profit can be higher with a quality‐dependent wholesale price contract than with a revenue‐sharing contract, specifically when the upstream supplier's innovation cost is low. We then extend our model to incorporate upstream competition between suppliers. By inviting upstream competition, with the wholesale price contract, the manufacturer can increase his profit substantially. Furthermore, under upstream competition, the revenue‐sharing contract coordinates the supply chain, and results in an optimal contract form for the manufacturer when suppliers are symmetric. We also analyze the case of complementary components suppliers, and show that most of our results are robust.     

Hope for Haiti: An analysis of Facebook and Twitter usage during the earthquake relief efforts

The Haitian earthquake devastated the small island of Hispaniola, leaving thousands dead and billions of dollars in property damage. The earthquake also ignited a firestorm of social media use by organizations. By applying framing theory to the analysis of Facebook posts and tweets sent by nonprofits and media organizations, this study discovered differences between nonprofits and media in terms of social media use. Nonprofits and media organizations used information dissemination and disclosure effectively, but failed to capitalize on the innate two-way communication nature of social media.     

The Gulf Coast oil spill: Extending the theory of image restoration discourse to the realm of social media and beyond petroleum

The explosion of Transocean's Deepwater Horizon, an oil-rig licensed to BP, set in motion a chain of unfortunate events that led to BP's ruptured oil well disgorging millions of gallons of oil into the Gulf of Mexico. Since the spill, the corporate image of BP has been severely challenged. The company has used many strategies to preserve and restore the corporate image, and has sought means to mitigate the intensity of the ongoing threat to individuals, businesses, and a delicate ecosystem. Among these means are interacting with individuals and interest groups through social media channels. Benoit's (1995) theory of image restoration discourse posits various strategies corporations use to restore their image during a crisis. The BP crisis presents an opportunity to extend the theories of image restoration to the realm of social media. Results of a content analysis showed that corrective action was the dominant image restoration strategy employed by BP in their Facebook, Twitter, YouTube and Flickr pages. A high presence of negative emotions revealed that corrective action was not an effective means of swaying public opinion in favor of BP's efforts. Dominant themes in all four social media channels and audience comments in terms of dominant issues and emotions on Facebook and YouTube were also analyzed.     

The Residential Choices of Ethnic Elders in Affordable Housing: Changing Intergenerational Relationships and the Pursuit of Residential Independence

This study examines the housing choices and residential experiences of ethnic minority elders in affordable senior housing in a large metropolitan area by using a life course perspective in the context of community life. Using in-depth interview data with 138 individuals, the study reveals that the elders’ decisions to move were fueled by their evolving intergenerational relationships, suburban isolation, governmental provisions of housing and health care, and ethnic concentrations in urban centers. Place meanings arose from the relationship between life course factors, urban configuration, and health care provision as they unfolded in a community boundary of the activity setting.     

Social and Health Service Use and Treatment Outcomes for Sexual Minorities in a National Sample of Substance Abuse Treatment Programs

This study examines substance use severity, levels of social and health service utilization, and the impact of service utilization on treatment outcomes for sexual minorities versus non-minorities. The sample included 3,094 clients from the National Treatment Improvement Evaluation Study (NTIES). Substance use severity among sexual minorities and non-sexual minorities was similar at treatment entry and at 12 months post-discharge. Differences in social and health service utilization were significant for substance abuse counseling and health services. Significant interactions between sexuality and access services and sexuality and mental health services were also found. Practice and research implications are discussed.
