An Efficient and Robust Design for Transshipment Networks

Transshipment, the sharing of inventory among parties at the same echelon level of a supply chain, can be used to reduce costs. The effectiveness of transshipment is in part determined by the configuration of the transshipment network. We introduce chain configurations in transshipment settings, where every party is linked in one connected loop. Under simplifying assumptions we show analytically that the chain configuration is superior to configurations suggested in the literature. In addition, we demonstrate the efficiency and robustness of chain configurations for more general scenarios and provide managerial insights regarding preferred configurations for different problem parameters.     

Learning organization,organizational culture,and affective commitment in Malaysia: A person–organization fit theory

ABSTRACT

Based on person–organization fit theory, this article moves beyond theories of motivation and social exchange relationships that have often been used in commitment literature. This article contributes to understanding perceptions of organizational culture (OC) and affective commitment (AC) through perceptions of a learning organization (LO). Such understanding helps to tackle current commitment issues in Malaysia through strategic human resources development (HRD) planning and deploying organization development activities. We examined: (a) the extent to which organizations with an embraced LO mediated OC and AC, (b) the most influential component of OC in promoting employee AC, and (c) the most important component of LO for influencing OC and AC. We obtained 516 respondents (64.5% response rate) in selected Malaysian private organizations. It was concluded that LO mediated the relationship between OC and AC. Respect for people was an influential factor of OC for AC, while empowerment played a significant role in LO culture mediating the relationship between OC and AC. HRD practitioners should strategically plan organizational activities, norms, and policies that promote organizational learning processes and a learning culture to enhance AC.     

Managerial Thinking on Value-Based Management

This study explores how managers perceive the issue ofcreating `common values,' what change strategies theyprefer, and their reflection on `value-basedmanagement.'Common values are the glue which binds anorganization together; they motivate and createa sense of community. If properly implemented, theemployees can be trusted in the absence of directrules and regulations. Most managers embrace a holistic view of man on a rhetorical level, but thewell-being of the company has priority in practice.Given these assumptions, held reluctantly orimplicitly, there is little leeway for democraticmanagement.This methodological reduction of man mostlyremains hidden. Without an open discussion, suchshort-term deviations from an ideal situation runthe risk of being a permanent conflict in the companyculture, or lead to an ontological reduction ofman.     

Diskussionslinien der Entrepreneurial Marketing-Forschung: Ergebnisse einer Zitationsanalyse

Entrepreneurial Marketing (EM) is a research field that grows dynamically and that seems to be heterogeneous. Heterogeneity of a research field exacerbates the orientation in and the advancement of the field. Therefore, this article strives to inventarize the EM-literature and thereby to identify key discussion lines of EM research.Based on a comprehensive literature analysis, we first outline the history of EM research, and identify core authors and core journal Based on a citation analysis of 199 EM papers with a total of 6,222 references and an ensuing expert evaluation, we identify four key discussion lines: (1) theoretical foundations, (2) entrepreneurship-marketing interface, (3) new venture- and SME-marketing, and (4) EM in the sense of innovative, proactive and risk-oriented marketing. These four discussion lines and the respective literature constitute a framework for the advancement of EM research.     

Places of socialization and (sub)ethnic identities among Asian immigrants in the US: evidence from the 2007 Chinese American Homeland Politics Survey

This research provides an empirical assessment of the relationship between places of socialization and ethnic self-identity preferences among Asian immigrants in the US from separate parts of a politically divided homeland. Does place of socialization influence the (sub)ethnic self-identity of Chinese Americans raised in China, Taiwan and Hong Kong? How do socialization context and transnational political concerns, among other factors, help structure the relationship? Benefiting from recent advancements in targeted ethnic sampling and telephone survey methodology, this paper examines results of the 2007 Chinese American Homeland Politics Survey to study the contour and sources of ethnic identity preferences among Chinese in the US from separate homeland origins. The usefulness of a theoretical framework that contrasts primordial ties with transnational political ties in understanding the structuring of identity preferences at the subethnic level is tested.     

Initial Career and Work Meanings in Seven European Countries

This study explores the initial careers of two target groups of young adults in seven European countries. Career patterns have been constructed through cluster analysis on data gathered from the young adults through a retrospective self-report procedure covering a period of 2.5 years. Six career patterns have been identified across countries by the activities taking place (employment, various educational preparations, unemployment, military or civil service) and have been further described by personal and work-related variables as well as by meaning of work indices (work centrality, intrinsic versus extrinsic work orientations, and societal norms about working) and psychological well-being in the second year on the labor market. Suggestions for further research as well as the implications for career counseling, career education, organizational career guidance and development have been given.     

Asymmetric information and the brain drain

Within an asymmetric information framework, we investigate the effects of subsidies for return when the size of the foreign student population is endogenous. Given the stability condition and the assumption that the education system is effective in the home country, we show that susidies for return always act to improve the average ability of returning Ph. D. s but the impact upon the number of emigrants is ambiguous. As a consequence, subsidies for return may be ineffective for a general, reasonable government objective function. Also, we show that the number of emigrants with asymmetric information structure may be smaller than the case of symmetric information due to uncertainties present in our model.I am greatly indebted to Robert Bates, Mohamed EI-Hodiri, James Quirk, Joseph Sicilian, DeMin Wu, and an anonymous referee for helpful discussions and comments. Of course, I am solely responsible for any remaining errors. The research is, in part, supported by a grant from the University of Kansas, GRF 3281-XX-0038     

SELLING TO BIASED BELIEVERS: STRATEGIES OF ONLINE LOTTERY TICKET VENDORS

We provide evidence that sellers respond to buyers' belief biases in a collective lottery betting market, by adopting sales strategies which cater to believers in the Hot Hand and Gambler's Fallacies. Lottery players on the buyer side tend to avoid buying tickets which are similar to the previous winning ticket, in accordance with the Gambler's Fallacy (Clotfelter and Cook 1993; Terrell 1994). At the same time, buyers tend to prefer purchasing tickets from previously winning sellers, despite the fully random nature of wins, in accordance with Hot‐Hand Fallacy (Croson and Sundali 2005). These behavioral biases provide an opportunity for ticket sellers to increase their expected profits by adjusting features of the lottery portfolios they sell. We find that sellers make changes to their portfolio size, commission rate, self‐purchase rate, and number choices in response to previous events, in ways that are consistent with responding to the Hot‐Hand Fallacy belief, and which also lend a degree of support for responding to the Gambler's Fallacy belief. Our results show evidence of participants in a market accommodating their choices to the biased beliefs of other participants in order to gain an advantage in expected profits.

The decycling number of outerplanar graphs

For a graph G, let τ(G) be the decycling number of G and c(G) be the number of vertex-disjoint cycles of G. It has been proved that c(G)≤τ(G)≤2c(G) for an outerplanar graph G. An outerplanar graph G is called lower-extremal if τ(G)=c(G) and upper-extremal if τ(G)=2c(G). In this paper, we provide a necessary and sufficient condition for an outerplanar graph being upper-extremal. On the other hand, we find a class $\mathcal{S}$ of outerplanar graphs none of which is lower-extremal and show that if G has no subdivision of S for all $S\in \mathcal{S}$ , then G is lower-extremal.
