    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

    Axiomatic Testing of Structure Metrics

    Axiomatic testing of software metrics is described, based on axioms from representational measurement theory. In a case study, the axioms are given for the formal relational structure and the empirical relational structure. Two approaches to axiomatic testing are elaborated: deterministic testing and probabilistic testin

    Learning labelled dependencies in machine translation evaluation

    Recently novel MT evaluation metrics have been presented which go beyond pure string matching, and which correlate better than other existing metrics with human judgements. Other research in this area has presented machine learning methods which learn directly from human judgements. In this paper, we present a novel combination of dependency- and machine learning-based approaches to automatic MT evaluation, and demonstrate greater correlations with human judgement than the existing state-of-the-art methods. In addition, we examine the extent to which our novel method can be generalised across different tasks and domains
