The Impact of Information Sharing and Advance Order Information on a Supply Chain with Balanced Ordering

This paper considers a supply chain with one supplier and multiple retailers that face exogenous heterogeneous end‐customer demands, where all parties utilize base‐stock policies. Each retailer is restricted to order once in every order cycle and their orders are replenished in a balanced manner within the cycle. Our study investigates the impact of information sharing and advance order information (AOI) on the supply chain. We find that the supplier benefits from the two mechanisms via two important factors, the information about observed end‐customer demands and the decision on re‐establishing the replenishment sequence. We derive the supplier's optimal sequence for stochastically comparable end‐customer demands with AOI and propose a sequencing rule for the setting with information sharing. Our numerical study examines the cost impacts of two proposed mechanisms on the entire supply chain.     

Bayesian inference of three-parameter bathtub-shaped lifetime distribution

We investigate a Bayesian inference in the three-parameter bathtub-shaped lifetime distribution which is obtained by adding a power parameter to the two-parameter bathtub-shaped lifetime distribution suggested by Chen (2000). The Bayes estimators under the balanced squared error loss function are derived for three parameters. Then, we have used Lindley's and Tierney–Kadane approximations (see Lindley 1980; Tierney and Kadane 1986) for computing these Bayes estimators. In particular, we propose the explicit form of Lindley's approximation for the model with three parameters. We also give applications with a simulated data set and two real data sets to show the use of discussed computing methods. Finally, concluding remarks are mentioned.     

Finding Primary Publics: A Test of the Third-Person Perception in Corporate Crisis Situations

Exaggerated projections of the 3rd-person effect of crisis news on target groups may play a key role in escalating corporate crises. A 2 (locus of control: internal vs. external) × 2 (product category of crisis: food vs. laptop) experiment found that the 3rd-person perception varies as a function of product category. Our results indicated that in a laptop product category crisis, participants perceived target audiences to be more influenced than themselves when locus of control was internal rather than when it was external. This study delved into the potential effect on target groups and the corporation resulting from possible exaggerated perceptions of the impact of the crisis on the target groups. This perception may prompt or even pressure target audiences to react more strongly in keeping with the perceived impact, not their actual concern with the crisis. In turn, corporations may respond to a target audience based on the reaction the target audience feels obligated to portray in response to perceived impact, not actual impact measured independently in various ways.     

Organizational Linkages among the Inner Group of the Capitalist Class

Abstract

This study investigates the non-corporate organizational linkages among the inner group of the capitalist class, defined as those who are interlocked with three or more corporations. To the extent that persons already linked through corporate ties also are connected through common memberships in business organizations, social clubs, and other voluntary organizations, the likelihood of a national cohesive power elite is increased. The corporate data used are from the 1976 government study of the 130 major companies in the United States, controlling collectively 25 percent of all assets. The biographical data on the 66 individuals found to sit on three or more boards among these 130 companies were taken from Who's Who. Several key organizations were found where the members of the elite were especially interconnected. A cluster of 15 individuals with 13 or more common memberships within the 66 were identified as having the greatest linkages. The analysis of the number of common links for each possible pair among these 15 individuals revealed an average of 2.76. Moreover, one-third of the 15 had four links or more, with at least five persons among this inner circle, revealing the nucleus of the inner group. These data show that there is a social network, national in scope, which provides a basis for unity among leaders of the capitalist class.     

‘Ways of Remembering’: Transatlantic Connections and African Diaspora's Homecoming in the Republic of Benin

Abstract

Since the seventeenth century, the Atlantic ‘perimeter’ has been characterised by exchanges of commodities, bodies and cultural productions. Within this space, West Africa has established itself as an ‘ancestral land’: a pivotal physical and imagined location for its diaspora. Exploring how a ‘homeland’ is constructed, the article analyses practices of homecoming in the contemporary Republic of Benin. It argues that the particular historical conjuncture of the early 1990s, mainly characterised by the democratic transition, has allowed the restoration of Atlantic connections. Aspiring to establish a vibrant tourism industry, the new government strongly encouraged African American homecomings, commemorating the slave trade and celebrating diasporic cultures. The Vodun religion, because of its propagation across the New World through the slave trade, became the core symbol of this reunion, the very evidence of the strength of ancestral linkages and a foundation for black commonality. Reframing notions of ancestry and transnational belongings, the article examines how the insertion of Benin into global, economic and cultural circuits has led to the emergence of new cultural practices, meanings and subjectivities, both related to national and diasporic spaces.     

A Study of Online Auction Sellers’ Intention to Switch Platform: The Case of Yahoo!Kimo Versus Ruten_eBay*

The study of consumers’ switching from one service provider to another has a long tradition in economics, information systems, and marketing. The emergence of electronic commerce presents new challenges in understanding consumers’ switching intentions in the context of e‐commerce in general and online auctions in particular. With the abundance of literature on online auctions, there is a surprising lack of research on auction sellers’ intentions to switch from one online auction platform to another. Using the competition between Yahoo!Kimo and Ruten_eBay, two leading auction platforms in Taiwan, as the backdrop, we developed a research model and collected empirical data based on this real case to study what factors influence auction sellers to switch to a competing service provider. We find that the higher the procedural switching costs, financial switching costs, relational switching costs, site design quality, or interaction quality, the lower the intention of an auction seller to switch to a competing auction service provider. A higher perceived transaction fee, however, leads to a higher switching intention.     

A Joint Modeling Approach for Longitudinal Outcomes and Non-ignorable Dropout under Population Heterogeneity in Mental Health Studies

The paper proposes a joint mixture model to model non-ignorable drop-out in longitudinal cohort studies of mental health outcomes. The model combines a (non)-linear growth curve model for the time-dependent outcomes and a discrete-time survival model for the drop-out with random effects shared by the two sub-models. The mixture part of the model takes into account population heterogeneity by accounting for latent subgroups of the shared effects that may lead to different patterns for the growth and the drop-out tendency. A simulation study shows that the joint mixture model provides greater precision in estimating the average slope and covariance matrix of random effects. We illustrate its benefits with data from a longitudinal cohort study that characterizes depression symptoms over time yet is hindered by non-trivial participant drop-out.KEYWORDS: Latent growth curve, MNAR drop-out, survival analysis, finite mixture model, mental health     

Complicated narratives of ‘Korean-ness’: towards strategic provisionality in parental involvement

The purpose of this paper is to advance the discourse on parental involvement drawing from Butlerian notion of strategic provisionality. In developing a new approach to understanding cultural differences and their relation to Korean parental involvement, the authors analyze qualitative and quantitative data from five New York metropolitan elementary schools. The authors examine the ways in which ‘Korean-ness’ and Korean parental involvement are discursively constructed and embodied in sociopolitical and historical contexts in the United States. We present two themes related to Korean parental involvement: (a) the double-edged component of respect for teachers and (b) biopolitics related to English language and parental involvement. By challenging normalized understanding about Korean-ness, the authors suggest a different approach to ethnoepistemology in order to enrich discourses concerning parental involvement and ethnic/racial studies.     

Trends in Domestic and International Social Work Research: A 10-Year Review of American Research Journals

ABSTRACT

This article presents a typology of international social work research and analyzes trends over a 10-year period (1995–2004) based on reviews of 707 articles from three major American social work research journals: Social Work Research, Journal of Social Service Research, and Research on Social Work Practice. The analysis revealed there was a considerable increase (3.5%) in the total amount of research articles, particularly a higher increase in international social work research (2.8%) than national social work research (0.8%). A small decline was detected in transnational comparative research (?0.4%).     

Membership Benefits Matter

Professional associations have provided various benefits to their members to bolster member retention and recruitment. This study explored factors that could influence members’ behavioral intentions in professional membership associations by surveying 13,229 members from eighteen associations. More specifically, this analysis focused on the effects of members’ perceptions of the personal and professional benefits offered by associations with which they are affiliated and their satisfaction with those benefits. Our results suggested that members’ perceptions of personal and professional benefits positively correlated with their intentions to renew and recommend membership. If a member perceived a higher level of benefits, he or she would demonstrate a greater likelihood of satisfaction with the benefits and therefore be more likely to renew membership or recommend it to others. This study could advance understanding of the factors that influence members’ behavioral intentions while also providing professional associations with strategies for retaining existing members.
