    Interpretation of the Global Anisotropy in the Radio Polarizations of Cosmologically Distant Sources

    We present a detailed statistical study of the observed anisotropy in radio polarizations from distant extragalactic objects. This anisotropy was earlier found by Birch (1982) and reconfirmed by Jain and Ralston (1999) in a larger data set. A very strong signal was seen after imposing the cut ∣RM−RMˉ∣>6|RM-\bar{RM}|>6 rad/m2^2, where RMRM is the rotation measure and RMˉ\bar{RM} its mean value. In this paper we show that there are several indications that this anisotropy cannot be attributed to bias in the data. We also find that a generalized statistic shows a very strong signal in the entire data without imposing the RM dependent cut. Finally we argue that an anisotropic background pseudoscalar field can explain the observations.Comment: 13 pages, 6 figure

    Institutional distance and knowledge acquisition in international buyer–supplier relationships::the moderating role of trust

    Institutional distance can generate expanded opportunities for multinational firms to facilitate learning and responsiveness. However, such distance can also create obstacles regarding knowledge transfer and integration. A theoretical puzzle concerns the mechanisms and conditions in which international buyers and suppliers can overcome institutional distance and acquire new knowledge. We develop an integrative moderated-mediation model in which institutional distance prevents parties from accessing knowledge but, when knowledge is obtained and mutual trust is developed, it promotes cross-border knowledge acquisition in international buyer-supplier exchange, particularly between international firms and firms from the Asia Pacific region. These findings indicate that firms can overcome the challenges of regulative and cognitive distance and facilitate access to knowledge and knowledge acquisition when they are able to develop and cultivate relationships of mutual trust with foreign partners. While normative distance may create learning incentives and opportunities in international buyer-supplier relationships, its impacts on knowledge accessibility and acquisition are insignificant.fi=vertaisarvioitu|en=peerReviewed

    Cultural Distance and Firm Internationalization:A Meta-Analytical Review and Theoretical Implications

    This paper presents the most comprehensive review and meta-analysis of the literature on cultural distance and firm internationalization to date. We analyze the effects of cultural distance on key strategic decisions throughout the entire process of internationalization. For the preinvestment stage, we examine the decisions on where to invest (location choice), how much to invest (degree of ownership), and how to organize the foreign expansion (entry and establishment mode). For the postinvestment stage, we examine the decisions of how to integrate the foreign subsidiary into the organization (transfer of practices) as well as the performance effects of cultural distance at both the subsidiary and the firm level. We find that firms are less likely to expand to culturally distant locations but if they do, they prefer greenfield investments and integrate subsidiaries more through transfer of management practices. Cultural distance does not seem to affect how much capital firms invest and whether they enter through a joint venture or full ownership. Interestingly, cultural distance has a strong negative effect on subsidiary performance but no effect on the performance of the whole multinational company. In addition, we find that the effects of cultural distance are not sensitive to time, but they are sensitive to the cultural framework used (e.g., Hofstede vs. Global Leadership and Organizational Behavior Effectiveness) and the home country of the company (developed vs. emerging market). Based on our study, we feel confident to offer some theoretical insights, recommendations for improving the validity and reliability of cultural-distance research, and ideas for future research

    Family Business Restructuring:A Review and Research Agenda

    Get PDF
    Although business restructuring occurs frequently and it is important for the prosperity of family firms across generations, research on family firms has largely evolved separately from research on business restructuring. This is a missed opportunity, since the two domains are complementary, and understanding the context, process, content, and outcome dimensions is relevant to both research streams. We address this by examining the intersection between research on business restructuring and family firms to improve our knowledge of each area and inform future research. To achieve this goal, we review and organize research across different dimensions to create an integrative framework. Building on current research, we focus on 88 studies at the intersection of family firm and business restructuring research to develop a model that identifies research needs and suggests directions for future research

    CEO narcissism and global performance variance in multinational enterprises : the roles of foreign direct investment risk-taking and business group affiliation

    No full text
    This study examines key mechanisms through which CEO narcissism influences global performance variance in the context of Asian emerging market multinational enterprises (AEMNEs). 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 MNEs 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
