In chemical and microbial risk assessments, risk assessors fit dose‐response models to high‐dose data and extrapolate downward to risk levels in the range of 1–10%. Although multiple dose‐response models may be able to fit the data adequately in the experimental range, the estimated effective dose (ED) corresponding to an extremely small risk can be substantially different from model to model. In this respect, model averaging (MA) provides more robustness than a single dose‐response model in the point and interval estimation of an ED. In MA, accounting for both data uncertainty and model uncertainty is crucial, but addressing model uncertainty is not achieved simply by increasing the number of models in a model space. A plausible set of models for MA can be characterized by goodness of fit and diversity surrounding the truth. We propose a diversity index (DI) to balance between these two characteristics in model space selection. It addresses a collective property of a model space rather than individual performance of each model. Tuning parameters in the DI control the size of the model space for MA. 相似文献

This study identifies the substantial relationship between corporate social responsibility (CSR) and innovation activities of firms. Using the French Vigeo sustainability rating and the Thomson Reuters, we divided 619 firms into groups by their industry sectors, regions, and firm characteristics such as size and age. We premise that innovative investment is needed to prepare tomorrow's profits not only by considering investments in technology and in R&D, but also by dealing with sustainability to human, social, environmental, technical, and economic investments. Consequently, when the firm manipulates its short- and long-run business strategies, the consideration of the correlation between types of investment and CSR initiatives will lead to more cooperating effect on the outcome of investments. The findings provide a comprehensive understanding on the effect of sustainable management strategies on the innovation and sustainability of firms. 相似文献

Authority figures may organize show trials featuring public confessions when they are faced with deep rooted contradictions within the social order and want to increase their legitimacy, delegitimize defendants, and justify increased social control in society. An analysis of the court report of the Moscow Show Trials found that these public confessions frame conflicts rooted in contradictions within the social order as acts of deviance that can be resolved with additional social control. The public confessions accomplished this using four main themes: establishing credibility, labeling the defendants as deviant, endorsing the power holder, and demonstrating closure. 相似文献

The expansion of legalized commercial gaming in Macau has motivated stakeholders to explore opportunities in other Asian countries. However, there is a lack of research focusing on casino customers in these markets. Thus, the purpose of this study is to explore gambling superstitious beliefs and motivations of those visiting a casino in South Korea, and how these factors are different across four ethnic groups. The researchers surveyed 323 casino customers in the lounge area on the casino floor, including Americans, Chinese, Japanese, and Koreans living abroad. This study found American gamblers could be characterized as more superstitious than Japanese gamblers, while the Chinese and American gamblers exhibited many similarities regarding the pattern of superstitious beliefs that they were most likely to endorse. The findings also suggest the culture and the area around the casino might be more important to Chinese, while novelty to Japanese and winning money to Korean gamblers are seen as most important. This study contributes to gambling literature by examining gamblers’ beliefs and motives in a different setting with more diverse populations than those in previous studies. The findings of this study will help casino operators properly develop and adjust strategies to thrive in the Asian marketplace. 相似文献

This study examined the role of personality traits in the receipt of financial help at older ages using the 2006 and 2008 waves of Health and Retirement Study data. An investigation of (1) how the five domains of personality traits (openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism) are associated with the receipt of financial help among older adults and (2) the relationship between personality traits and the source of financial help received was examined. Three sets of probit analyses were conducted. The results indicated that personality can predict financial help and the source of financial help. Specifically, older adults who exhibited relatively higher levels of neuroticism and agreeableness were more likely to receive financial help, whereas those who exhibited relatively higher levels of conscientiousness were less likely to receive financial help regardless of the source. Furthermore, older adults who had relatively higher levels of neuroticism were more likely to help themselves with individual sources such as credit cards whereas agreeable older adults were more likely to receive financial help from family members. These findings have implications for financial counseling, planning and education professionals, public assistance program directors, and policy makers. Understanding the effect of personality on financial decision-making can help with financial planning throughout life and inform outreach efforts for those in need of financial help. 相似文献

La gouvernance privée telle qu'elle découle des différentes initiatives prises par les multinationales pour promouvoir le respect de normes sociales et l'égalité hommes‐femmes a eu peu d'effet sur les discriminations fondées sur le genre dans les chaînes d'approvisionnement mondiales. Les auteures soulignent l'intérêt des Principes directeurs des Nations Unies relatifs aux entreprises et aux droits de l'homme en la matière, estimant qu'il est indispensable de recourir à une gouvernance «stratifiée» associant public, privé et acteurs sociaux pour lutter contre cette discrimination et intégrer le souci de l'égalité des sexes dans l'exercice de la diligence raisonnable exigée en matière de droits de l'homme. 相似文献

Outsourcing has been a key policy tool for delivering a range of social services, and regarded as more effective than insourcing or direct government provision. At the same time, it has also caused many delivery issues such as principal‐agent problems, a lack of policy coordination, and poor‐quality welfare services. While the pendulum continues to swing between insourcing and outsourcing, we aim to propose a new public–private partnership model called the “hybrid insourcing model” and examine which factors influence the performance of the model. In South Korea, around 2010, the local government in Namyangju City was the first to implement the “Hope Care Center model,” a kind of hybrid insourcing model, which has been praised for its innovation and widely emulated by central and local governments. Our analysis utilizes data collected between December 2017 and January 2018 from public sector employees and civilian staff in Namyangju and a comparable city, A. From this, we draw a number of implications, both for theory and for policy. We argue that, for public–private partnerships, active cooperation and equality are the biggest factors in contributing to positive performance. These work alongside leaders with a clear vision and with employees' positive attitude. 相似文献

Using a survey of 405 full-time employees, this study examined how organizations’ internal communication influenced by leadership communication at the supervisory- and senior-levels impacts employee creativity and how employees’ feedback-seeking behaviors mediate these relationships. The results suggest that leadership communication at the supervisory and senior levels positively influence symmetrical internal communication system. The analysis also shows that symmetrical internal communication and leadership communication cause employees to seek more feedback from different interpersonal sources including supervisors, coworkers, and peers in other departments, which in turn enhances creativity. This paper concludes with a discussion of the theoretical and practical implications of these findings for public relations and internal communication. 相似文献
