Examining the Link Between Diversity and Firm Performance: The Effects of Diversity Reputation and Leader Racial Diversity

Given the scarcity of empirical research on the impact of diversity on organizational performance, we used longitudinal data for 100 firms to test hypotheses related to the effects of diversity reputation and leader racial diversity on firm financial outcomes. The results showed a positive relationship between diversity reputation and book-to-market equity, and a curvilinear U-shaped relationship between leader diversity and revenues, net income and book-to-market equity. Our analyses suggest that economic benefits generated from diversity reputation may primarily derive from capital rather than product markets. Further, firm performance declines with increases in the representation of racial minorities in leadership up to a point, beyond which further increases in diversity are associated with increases in performance

Discovering the Sources of TFP Growth: Occupation Choice, Capital Heterogeneity, and Financial Deepening

The sources of "total factor productivity (TFP) growth" or the "Solow residual" typically remain unknown as a residual. This paper aims to identify the underlying sources of this residual growth, being explicit about micro underpinnings and transitional growth from occupation choices of heterogeneous agents and financial deepening in use of both macro and micro data. We develop a method of growth accounting that decomposes not only the overall growth but also the residual TFP growth into four components: occupational shifts, financial deepening, capital heterogeneity, and sectoral Solow residuals. Applying this method to Thailand, which experienced rapid growth with enormous structural changes for the two decades between 1976 and 1996, we find that 55 percent of TFP growth can be explained on average by occupational shifts and financial deepening, without presuming exogenous technical progress. Expansion of credit is a major part of this explained TFP growth. Decomposition of the simulation helps us to infer that for the remainder TFP growth, capital-heterogeneity effect is behind during the initial period (1976-1980) while sectoral Solow residuals, due to the surge of wage after 1986, is behind during the latter decade (1986-1996)TFP, Capital Heterogeneity, Occupation Choice, Financial Deepening

Production of entanglement with highly-mixed states

We study production of entanglement with highly-mixed states. We find that entanglement between highly mixed states can be generated via a direct unitary interaction even when both states have purities arbitrarily close to zero. This indicates that purity of a subsystem is not required for entanglement generation. Our result is in contrast to previous studies where the importance of the subsystem purity was emphasized.Comment: 4 pages, 5 figure

Input-output relations for multiport ring cavities

Quantum input-output relations for a generic $n$-port ring cavity are obtained by modeling the ring as a cascade of $n$ interlinked beam splitters. Cavity response to a beam impinging on one port is studied as a function of the beam-splitter reflectivities and the internal phase-shifts. Interferometric sensitivity and stability are analyzed as a function of the number of ports.Comment: 6 pages, 5 figures (low-res

Near-deterministic quantum teleportation and resource-efficient quantum computation using linear optics and hybrid qubits

We propose a scheme to realize deterministic quantum teleportation using linear optics and hybrid qubits. It enables one to efficiently perform teleportation and universal linear-optical gate operations in a simple and near-deterministic manner using all-optical hybrid entanglement as off-line resources. Our analysis shows that our new approach can outperforms major previous ones when considering both the resource requirements and fault tolerance limits.Comment: 10 pages, 5 figures; extended version, title, abstract and figures changed, details added, to be published in Phys.

HR Practices and Customer Satisfaction: The Mediating Link of Commitment

This research examined organizational commitment as a mediator between HR practices and customer satisfaction of 35 job groups from 13 service firm business units. Both commitment level and consensus were predicted to influence customer satisfaction. Results found that commitment level mediated the relationship between HR practices and customer satisfaction

Testing non-local realism with entangled coherent states

We investigate the violation of non-local realism using entangled coherent states (ECS) under nonlinear operations and homodyne measurements. We address recently proposed Leggett-type inequalities, including a class of optimized incompatibility ones and thoroughly assess the effects of detection inefficiency.Comment: 7 pages, 6 figures, RevTeX4, accepted for publication in Phys.
