Relativistic Binaries in Globular Clusters

Galactic globular clusters are old, dense star systems typically containing 10\super{4}--10\super{7} stars. As an old population of stars, globular clusters contain many collapsed and degenerate objects. As a dense population of stars, globular clusters are the scene of many interesting close dynamical interactions between stars. These dynamical interactions can alter the evolution of individual stars and can produce tight binary systems containing one or two compact objects. In this review, we discuss theoretical models of globular cluster evolution and binary evolution, techniques for simulating this evolution that leads to relativistic binaries, and current and possible future observational evidence for this population. Our discussion of globular cluster evolution will focus on the processes that boost the production of hard binary systems and the subsequent interaction of these binaries that can alter the properties of both bodies and can lead to exotic objects. Direct {\it N}-body integrations and Fokker--Planck simulations of the evolution of globular clusters that incorporate tidal interactions and lead to predictions of relativistic binary populations are also discussed. We discuss the current observational evidence for cataclysmic variables, millisecond pulsars, and low-mass X-ray binaries as well as possible future detection of relativistic binaries with gravitational radiation.Comment: 88 pages, 13 figures.

The Core Value Compass: visually evaluating the goodness of brands that do good

yesBrands that do good for the society as well as for themselves are motivated by the core values they espouse, which necessitates a better understanding of what qualities a true core value must possess. The inherent tension within brands that do good, between commercial interests to increase competitiveness, and societal interests that are closely linked to the brand’s authenticity, has largely been overlooked. Hence, we develop and demonstrate a relatively easy-to-apply visual tool for evaluating core values based on a set of ‘goodness’ criteria derived from extant theory. The Core Value Compass adopts a paradox-based, evolutionary perspective by incorporating the inherent tensions within true core values, and classifying them according to their temporal orientation. Thus, we contribute towards a better understanding of underlying tensions of core values and provide a practical tool that paves the way for improved, and indeed ethical, corporate branding strategies. Furthermore, we demonstrate the Compass’ application using the case of a public sector brand, which is a quintessential brand that does good. Therefore, we also contribute to the nascent theoretical discourse on public sector branding. This paper therefore adds to the notable attempts to bridge the gap between theory and practice in core values-based corporate branding

Path-Breakers: How Does Women's Political Participation Respond to Electoral Success?

This paper analyzes the effect of a woman's electoral victory on women's subsequent political participation. Using the regression discontinuity afforded by close elections between women and men in India's state elections, we find that a woman winning office leads to a large and significant increase in the share of female candidates from major political parties in the subsequent election. This stems mainly from an increased probability that previous women candidates contest again, an important margin in India where a substantial number of incumbents do not contest re-election. There is no significant entry of new female candidates, no change in female or male voter turnout and no spillover effects to neighboring areas. Further analysis points to a reduction in party bias against women candidates as the main mechanism driving the observed increase in women's candidacy

Validity of Scores on the Attitudes toward Diversity Scale (ATDS)

The Attitudes Toward Diversity scale (ATDS) was developed to measure the construct of attitudes toward diversity. It consists of 10 items representing each of three domains: attitudes toward diversity with regard to (a) coworkers, (b) supervisors, and (c) hiring and promotion decisions. To determine psychometric characteristics of scale scores, 349 full-time workers completed the instrument. Subjects included firefighters, police officers, first-line supervisors, technologists, clerical/secretarial workers, and managers. Confirmatory factor analysis indicates that the ATDS is three-dimensional, as hypothesized. Further analyses suggest that the scale has high internal consistency (a = .90) and is unaffected by a social desirability response style (r = -.09, n.s.)

Does brand authenticity alleviate the effect of brand scandals?

This research investigates to what extent brand authenticity lessens the impact of a brand scandal on consumer responses to the brand involved in the scandal. A 2 × 2 experiment shows that consumers responded more favourably to a more (vs. less) authentic brand in the event of a scandal. The protective effects of higher levels of brand authenticity emerged for emotional and behavioural brand outcomes (i.e., greater affection and willingness to pay) and brand-related inferences (i.e., lower perceived responsibility for the scandal and hypocrisy). Nonetheless, even a more authentic brand was harmed by a brand scandal (vs. no scandal). This suggests that the protective effect of brand authenticity does not fully compensate for the negative consequences of brand scandals. These findings give rise to theoretical and managerial implications
