Robust R-Estimation of a Consensus Value from Multi-Center Studies

We consider multi-center experiments (for determining a consensus value) conducted in possibly heterogeneous set-ups leading to unbalanced heteroscedastic one-way random effects models. When normality of both the random components and their homoscedasticity are in doubt, standard statistical methods may not be valid. Two robust R-estimators (for the common location parameter), based on signed-rank statistics, are proposed and their properties studied. When large heteroscedasticity is present or the distribution of random effect is abnormal, the proposed estimators perform better than the classical weighted least squares and selected estimators. This feature is illustrated with an arsenic in oyster tissue problem, along with some other simulation studies.     

New Approach of Directional Dependence in Exchange Markets Using Generalized FGM Copula Function

This article presents an application of copula methodology in exchange markets. In this article, we consider the concept of directional dependence given by Sungur (2005 Sungur , E. A. ( 2005 ). Some observations on copula regression functions . Communications in Statistics—Theory and Methods 34 : 1967 – 1978 .[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). We also consider and study directional dependence for generalized Farlie–Gumbel–Morgenstern (FGM) distributions, which are a member of the Rodríguez-Lallena and Úbeda-Flores (2004 Rodríguez-Lallena , J. A. , Úbeda-Flores , M. ( 2004 ). A new class of bivariate copulas . Statistical Probability Letters 66 : 315 – 325 .[Crossref], [Web of Science ®] , [Google Scholar]) family, C(u, v) = uv + f(u)g(v). Examples of the generalized FGM distributions are provided with exchange market data of the Euro, Canadian dollar, Korean Won, Japanese Yen, and Hong Kong dollar against the U.S. dollar.     

Multinomial Selection for Comparison with a Standard

The multinomial selection problem is considered under the formulation of comparison with a standard, where each system is required to be compared to a single system, referred to as a “standard,” as well as to other alternative systems. The goal is to identify systems that are better than the standard, or to retain the standard when it is equal to or better than the other alternatives in terms of the probability to generate the largest or smallest performance measure. We derive new multinomial selection procedures for comparison with a standard to be applied in different scenarios, including exact small-sample procedure and approximate large-sample procedure. Empirical results and the proof are presented to demonstrate the statistical validity of our procedures. The tables of the procedure parameters and the corresponding exact probability of correct selection are also provided.     

The Roles of Worker Expertise,Information Sharing Quality,and Psychological Safety in Manufacturing Process Innovation: An Intellectual Capital Perspective

This paper examines the roles of three elements of intellectual capital in implementing process innovations. Building upon prior literature, we develop a model describing how worker expertise, information sharing quality, and psychological safety work together as elements of the human, structural, and social dimensions of intellectual capital to influence the technical success of manufacturing process innovation (MPI) projects. Results of an analysis of data describing 179 MPI projects in US firms strongly support a multidimensional, process‐oriented view of intellectual capital's effects on MPI project technical performance. We also find that the incrementalness of an MPI project plays a moderating role over the relationship between worker expertise and MPI performance. Our study provides insights on how intellectual capital can be more effectively accumulated in a project environment.     

Paradoxes of social mobility in London

We analyse social mobility in London and seek to address two paradoxes. Among people living in London, relative mobility, or social fluidity, appears to be remarkably low when compared with other regions of Great Britain. But social fluidity among people who were brought up in London is similar to that of people brought up elsewhere in Britain. This is our first paradox. Furthermore, it is widely held that social fluidity is higher among people with higher levels of education, yet, the proportion of people with a University degree is much higher among people living in London than in any other region: how is this compatible with its relatively low social fluidity? This is our second paradox. We address these puzzles and find that they are largely explained by patterns of migration into and out of London by two groups that have received little attention hitherto in studies of mobility in the capital: International migrants and people who were brought up in London but who no longer live there.     

Evaluation of hazard brochures using topic viewing durations: Application to tsunami evacuation brochures

This study describes a novel method of assessing risk communication effectiveness by reporting an evaluation of a tsunami information brochure by 90 residents of three Pacific coast communities that are vulnerable to a Cascadia Subduction Zone earthquake and tsunami—Commencement Bay, Washington; Lincoln City, Oregon; and Eureka, California. Study participants viewed information that was presented in DynaSearch, an internet-based computer system that allowed them to view text boxes and tsunami inundation zone maps. DynaSearch recorded the number of times each text box or map was clicked and the length of time that it was viewed. This information viewing phase was followed by questionnaire pages assessing important aspects of tsunami hazard and sources of tsunami warnings. Participants gave the longest click durations to what to do in the emergency period during earthquake shaking and in its immediate aftermath before a tsunami arrives—topics that should be displayed prominently in tsunami brochures and emphasized in talks to community groups. The smallest adjusted click durations were associated with advance preparations for a tsunami—topics that can be posted on websites whose URLs are printed in the brochures.     

CEO Narcissism and Global Performance Variance in Multinational Enterprises: The Roles of Foreign Direct Investment Risk-Taking and Business Group Affiliation

This study examines key mechanisms through which CEO narcissism influences global performance variance in the context of Asian emerging market multinational enterprises. Building on the contextual reinforcement model of narcissism and the cushion hypothesis, we focus on the role of foreign direct investment (FDI) risk-taking and business group affiliation (BGA). We test our moderated mediation model on data from 149 South Korean multinational enterprises from 2006 to 2016. The results show that CEO narcissism is positively associated with FDI risk-taking. The effect of CEO narcissism on global performance variance is mediated by FDI risk-taking. Furthermore, BGA moderates the above-mentioned relationships. Our findings offer important contributions to the international business and CEO narcissism literatures.     

Enchanted companionship of Korean Catholic youth amid compressed individualization

Korean youth are confronted with “existential vulnerability” in an uncertain labor market. “Compressed individualization” reflects a high-risk society in Korea's socio-economic context and acts as the social backdrop for the “privatization of religion.” Despite de-religionization or the unchurching climate, what are the peculiar features of Korean Catholic youth who are actively participating in a church group? The authors selected five Catholic youth groups and conducted in-depth interviews with 18 of their members. Highly religious young Catholics demonstrate coping with existential insecurity amid compressed individualization via “enchanted companionship” experienced through prayer, sharing, or service. Despite differences in communal culture between groups, the peculiar features of their enchanted companionship include holistic healing, reciprocal transcendence, and solidarity. Amid the youth's struggles to find their way toward the fullness of life, these communities offer them a “free and gratuitous haven” distinct from secular ties in the utilitarian and disenchanted world. They can also voluntarily discover the significance of life through their activities, reflections, and missions. In sum, this study explains how religiosity is formed through a socio-existential vulnerability in youth's lived religion at a micro-level analysis, and signifies enchanted companionship as a key mechanism counteracting the waves of the secular world.     

Queering reproductive justice: Framing reproduction of gay men from a transnational perspective—Taiwan as a case

This article uses Taiwan as an example to argue that reproductive justice for gay men should be conceptualised within social, legal, and political contexts. Taiwan is the first Asian country to legalise same-sex marriage, yet the law favours heterosexual couples and denies LGBTQ+ reproductive rights. Thus, Taiwanese gay men seek third-party reproduction overseas to become parents. This article exemplifies gay men's unequal conditions from a non-Western perspective. I re-examine scholarly literature on the interlocking concepts of reproductive justice, stratified reproduction, and queer reproduction to answer what reproductive justice gay men need and how their injustice position situates within and beyond the nation-state borders. Drawing on the reproductive justice framework and studies of queer reproduction, this article proposes a transnational perspective to understand queer reproductive justice through the case that elucidates the specific context of Taiwanese gay men. This article aims to make two contributions. Firstly, it reconsiders the reproductive framework from a transnational perspective to argue that gay men's reproductive justice should be conceptualised at the intersection with other dimensions of injustice. Secondly, this article suggests that the transnational approach could be applied as a critical lens for future research in queer reproduction and reproductive justice.
