There’s More Than Meets the I(dentity): A Multidimensional View of Identity Threat

This dissertation provides a multiple identity perspective to how people experience challenges towards their identities ( identity threats ). While research on identity threat has normally focused on identity threat in relation to a single identity, my dissertation challenges this assumption by examining how connections between multiple identities (e.g., professional, spouse) affect how people experience identity threats. I provide a review of identity threat research, after which I establish an intrapersonal identity network view of identity threat that considers how the centralization of a threatened identity, as well as the density of one’s identity network in terms of enhancing and conflicting relationships, affects the relationship between identity threat and well-being. I develop and validate an empirical measure of identity threat using a sample of entrepreneurs, followed by an empirical test with a sample of unemployed, married workers. I then test a portion of my model with a sample of early career STEM academics by considering how competency beliefs associated with a current identity (self-efficacy, imposterism), shape the rate that workers obtain a clear vision of their future professional identity. Findings from this dissertation most squarely contribute to the identity threat literature, accounting for the complex and multifaceted ways that workers’ identities are connected within the identity threat process

Multinational Firms, Internal Capital Markets, and the Value of Global Diversification

Over the past 30 years, multinational firms’ investment grew four times faster than worldwide GDP. Yet the evidence on whether global diversification is valuable is inconclusive. This paper uses detailed foreign direct investment (FDI) data for 251 UK multinational firms and 4,676 subsidiaries for the period 1999–2005 to show that multinational firms exhibit, on average, a global diversification premium. I investigate this result and show that the premium is positively related to “winner-picking” transfers in internal capital markets, and more so for better-governed firms. The findings help explain why multinational firms’ investment and global diversification have significantly increased over the past three decades. </jats:p

The theory of international business: the role of economic models

This paper reviews the scope for economic modelling in international business studies. It argues for multi-level theory based on classic internalisation theory. It present a systems approach that encompasses both firm-level and industry-level analysis

Do the home field, global advantage, and liability of unfamiliarness hypotheses hold? empirical evidence from Malaysia

The study explores the home field, global advantage, and liability of unfamiliarness hypotheses in the Malaysian banking sector. The results indicate that Malaysian banks have exhibited productivity progress mainly attributed to technological progress. The authors find negative relationship between foreign and government ownership and bank productivity. Likewise, the publicly listed banks have been relatively less productive compared to private banks, thus rejecting the market discipline hypothesis. The empirical findings suggest that foreign banks from the North American countries to be the least productive banking group lending support to the home field advantage and the limited form of the global advantage hypotheses

Disentangling the effects of post-entry speed of internationalization on INVs’ export performance

This paper aims to explore the under-researched topic of post-entry speed of internationalization (PSI) in the context of international new ventures (INVs). We unbundle PSI and examine its relationship with both financial and non-financial export performance, considering three related, but conceptually distinct, dimensions of PSI: internationalization intensity, spread, and geographical diversity. Building on organizational learning theory, we highlight different mechanisms that contribute to post-entry performance outcomes among INVs. Our findings from a sample of 112 INVs in New Zealand provide evidence that the three dimensions of PSI are distinct and that they have different impacts on financial and non-financial export performance. This paper contributes to the limited, yet growing body of literature on PSI by providing a deeper understanding of PSI and its constituent dimensions. In addition, this study offers new theoretical insights into how and why different dimensions of post-entry speed of internationalization can contribute to stronger export performance

Target company cross-border effects in acquisitions into the UK

We analyse the abnormal returns to target shareholders in crossborder and domestic acquisitions of UK companies. The crossborder effect during the bid month is small (0.84%), although crossborder targets gain significantly more than domestic targets during the months surrounding the bid. We find no evidence for the level of abnormal returns in crossborder acquisitions to be associated with market access or exchange rate effects, and only limited support for an international diversification effect. However, the crossborder effect appears to be associated with significant payment effects, and there is no significant residual crossborder effect once various bid characteristics are controlled for

REAP: A two minute cell fractionation method

<p>Abstract</p> <p>Background</p> <p>The translocation or shuttling of proteins between the nucleus and cytoplasm (nucleocytoplasmic transport [NCPT]) is often a rapid event following stimulation with growth factors or in response to stress or other experimental manipulations. Commonly used methods to separate nuclei from cytoplasm employ lengthy steps such as density gradient centrifugation which exposes cells to non-physiological hyperosmotic conditions for extended time periods resulting in varying degrees of leakage between the nucleus and cytoplasm. To help maintain and quantify nuclear:cytoplasmic ratios of proteins, agents such as leptomycin B have been employed to be able to better analyze NCPT by inhibiting nuclear export. To track NCPT in the absence of these experimental manipulations that could introduce unknown artefacts, we have developed a rapid method that appears to produce pure nuclear and cytoplasmic fractions, suitable for obtaining accurate estimates of the nuclear:cytoplasmic ratios of proteins known to undergo NCPT.</p> <p>Findings</p> <p>We have developed a <b>R</b>apid, <b>E</b>fficient <b>A</b>nd <b>P</b>ractical (<b>REAP</b>) method for subcellular fractionation of primary and transformed human cells in culture. The REAP method is a two minute non-ionic detergent-based purification technique requiring only a table top centrifuge, micro-pipette and micro-centrifuge tubes. This inexpensive method has proven to efficiently separate nuclear from cytoplasmic proteins as estimated by no detectible cross-contamination of the nucleoporin and lamin A nuclear markers or the pyruvate kinase and tubulin cytoplasmic markers. REAP fractions also mirrored TNFα induced NF-κB NCPT observed in parallel by indirect immunofluorescence.</p> <p>Conclusions</p> <p>This method drastically reduces the time needed for subcellular fractionation, eliminates detectable protein degradation and maintains protein interactions. The simplicity, brevity and efficiency of this procedure allows for tracking ephemeral changes in subcellular relocalization of proteins while maintaining protein integrity and protein complex interactions.</p

Optimal geographic diversification and firm performance:evidence from the U.K.

This paper examines the relationship between multinationality and firm performance. The analysis is based on a sample of over 400 UK multinationals, and encompasses both service sector and manufacturing sector multinationals. This paper confirms the non-linear relationship between performance and multinationality that is reported elsewhere in the literature, but offers further analysis of this relationship. Specifically, by correcting for endogeneity in the investment decision, and for shocks in productivity across countries, the paper demonstrates that the returns to multinationality are greater than those that have been reported elsewhere, and persist to higher degrees of international diversification

Why Social Enterprises Are Asking to Be Multi-stakeholder and Deliberative: An Explanation around the Costs of Exclusion.

The study of multi-stakeholdership (and multi-stakeholder social enterprises in particular) is only at the start. Entrepreneurial choices which have emerged spontaneously, as well as the first legal frameworks approved in this direction, lack an adequate theoretical support. The debate itself is underdeveloped, as the existing understanding of organisations and their aims resist an inclusive, public interest view of enterprise. Our contribution aims at enriching the thin theoretical reflections on multi-stakeholdership, in a context where they are already established, i.e. that of social and personal services. The aim is to provide an economic justification on why the governance structure and decision-making praxis of the firm needs to account for multiple stakeholders. In particular with our analysis we want: a) to consider production and the role of firms in the context of the “public interest” which may or may not coincide with the non-profit objective; b) to ground the explanation of firm governance and processes upon the nature of production and the interconnections between demand and supply side; c) to explain that the costs associated with multi-stakeholder governance and deliberation in decision-making can increase internal efficiency and be “productive” since they lower internal costs and utilise resources that otherwise would go astray. The key insight of this work is that, differently from major interpretations, property costs should be compared with a more comprehensive range of costs, such as the social costs that emerge when the supply of social and personal services is insufficient or when the identification of aims and means is not shared amongst stakeholders. Our model highlights that when social costs derived from exclusion are high, even an enterprise with costly decisional processes, such as the multistakeholder, can be the most efficient solution amongst other possible alternatives
