The aim of this paper is to examine what kinds of CG mechanisms (institutional, firm or group level) are driving getting an Assurance or a GRI application level, like CSR disclosure decisions linked with credibility and usefulness of the information disclosed, in the particular context of energy companies. Previous evidence is scarce and does not jointly consider all levels of CG mechanisms. Our sample is composed by 176 energy companies worldwide which currently report about CSR through a sustainability report. On the basis of our findings, we could support the idea that the credibility of the CSR report of the utilities companies will be greater if the company listed in a Relation-Based country has an Assurance report. In addition, those companies that have a concentrated ownership and the fewer insiders sitting in the BoD present more probabilities of having an Assurance. Moreover, the usefulness of the CSR information provided by this kind of firms will be higher, the greater the efficiency of the BoD will be. The enhancement of the credibility and the usefulness of the information reported is essential for companies involved in this sector due to the frequent claim of window-dressing behaviours. 相似文献

We investigate the effect of female leadership on gender differences in public and private organizations. Female leadership impact was constructed using a quasi-experiment involving mayoral elections, and our research used a sample of 8.3 million organizations distributed over 5600 Brazilian municipalities. Our main results show that when municipalities in which a woman was elected leader (treatment group) are compared with municipalities in which a male was elected leader (control group) there was an increase in the number of top and middle female managers in public organizations. Two aspects contribute to the results: time and command/role model. The time effect is important because our results are obtained with reelected women – in their second term – and the command/role model (the queen bee phenomenon is either small, or non-existent) is important because of the institutional characteristics of public organizations: female leaders (mayor) have much asymmetrical power and decision-making discretion, i.e., she chooses the top managers. These top managers then choose middle managers influenced by female leadership (a role model). We obtained no significant results for private organizations. Our work contributes to the literature on leadership by addressing some specific issues: an empirical investigation with a causal effect between the variables (regression-discontinuity design – a non-parametric estimation), the importance of role models, and how the observed effects are time-dependent. Insofar as public organizations are concerned, the evidence from our large-scale study suggests that the queen bee phenomenon may be a myth; instead, of keeping subordinate women at bay, our results show that women leaders who are afforded much managerial discretion behave in a benevolent manner toward subordinate women. The term “Regal Leader” instead of “Queen Bee” is thus a more appropriate characterization of women in top positions of power. 相似文献

Research on interpersonal synchronization deals with the coordination of behavior, cognition and affect within interacting individuals. The phenomenon of synchronization has been explored in many settings and numerous definitions have emerged. The purpose of this study was to compare nonverbal synchrony (based on overall body movement) with the concept of complementarity (based on interpersonal theory) in a competitive context. We examined 40 previously unacquainted same-sex dyads (21 female, 19 male; mean age = 22.81). Dyads underwent a 15-min videotaped competitive role-play. Nonverbal synchrony was quantified by a frame-differencing method, and complementarity by a joystick tracking method. Results revealed that dyads behaved in a synchronous and complementary manner. We found that nonverbal synchrony was positively correlated with affiliation complementarity, but not dominance complementarity. The present study compared nonverbal synchrony with complementarity. The link between the two concepts was small, as indicated by rather weak correlations between nonverbal synchrony and affiliation complementarity. Our results reinforce the view that competitive behavior depends on complex dyadic interactions, including nonverbal and verbal behavior. 相似文献

Despite hip-hop’s popularity, little attention has been paid to its effects on youth gender performances on social media. This study has analyzed how youth who identify with three popular hip-hop songs interpreted the songs’ messages and performed their gender on the social media application Instagram (IG). Posts (N=450) from IG users were examined using modified consensual qualitative research procedures. Ten categories emerged that illustrate the range of gender performances which youth engaged in, each of which occurred within one of four domains: (a) mixed messages (self-love and visibility; relationships); (b) reified messages (party life; provocations; conspicuous consumption); (c) challenged messages (growth; making new meaning; teamwork); and (d) neutral messages (humor; other). The findings from this study illustrate the influential role of hip-hop music on youth gender performance in a natural context (IG). IG posts often mirrored, and in turn contributed to, the narrow range of acceptable gender performances in hip-hop, suggesting the need for youth media literacy skill development. 相似文献

ABSTRACT: In the aim to investigate the behaviour of some indicators for the industrial conflict and to detect the relation between such variables and the cost of labour in Italy, this paper suggests the use of Box-Jenkins’time series analysis. By fitting a different stochastic process for each series, it can be shown that every indicator gives a different kind of information about the industrial conflict, so that they can't be indifferently substituted by each other. In a second step, cross correlation function estimates between cost of labour and each indicator suggest the different role played by 'strike frequency’and strike duration during any contract renewal. 相似文献

This study examined the relationships between caregiver alcohol dependence, drug dependence, and serious mental illness and internalizing and externalizing behaviors and whether these risks were moderated by social support. The study included 3,225 children ages 2–17 and their current caregivers, who participated in the second cohort of the National Survey on Child and Adolescent Well-Being. Regression analysis indicated that caregiver alcohol dependence, serious mental illness, and social support were significantly associated with internalizing behaviors and caregiver serious mental illness and social support were significantly associated with externalizing behaviors. Results indicated that social support moderated the associations between caregiver alcohol dependence and internalizing and caregiver drug dependence and externalizing behaviors. Implications for practice and future research are discussed. 相似文献

The authors compare the determinants of three forms of marginal employment between Mexican-origin and white women: unemployment, involuntary part-time employment, and working poverty. They address two main questions. First, are there differences between Mexican-origin and white women in the propensity for unemployment, involuntary part-time employment, and working poverty? Second, do the effects of personal characteristics and job location on underemployment vary by ethnicity? Data are drawn from the Annual Social and Economic (ASEC) Supplement File of the 2005 Current Population Survey (CPS). Using multinomial logistic regression models, we show that ethnicity matters in the likelihood of working poverty but not for the other forms of underemployment. Results also reveal that the effects of personal attributes and job location on the likelihood of unemployment, involuntary part-time employment, and working poverty vary for each ethnic group, leading to a double disadvantage for working poor Mexican-origin women. 相似文献

ABSTRACTRural older women are surrounded by nature, a dynamic context for human development. Informed by place attachment and attention restoration theory, and guided by a life course perspective, this qualitative study focused on the perceived influence of nature in the lives of 34 rural older women. Using grounded theory techniques to analyze in-depth interviews, two primary findings emerged: (a) nature was integral to the women’s identity; and (b) interactions with nature were motivated by prior positive spiritual and psychological outcomes. Findings revealed the power of the natural environment as a resource for coping with the challenges associated with aging. 相似文献

This paper introduces some new models of ecological inference within the context of estimation of voter transitions across elections. In particular, we assume that voters of a given party in a given occasion may be split into two latent types: faithful voters, who will certainly vote again for the same party and movers, who will reconsider their choice. Our models allow for unobserved heterogeneity across polling stations both in the weights of the two latent classes within each party and also when modelling the choice of unfaithful voters. Different ways of modelling the unobserved heterogeneity are considered by exploiting properties of the Dirichlet-multinomial distribution and the Brown Payne model of voting transitions can be seen as a special case within the class of models presented here. We discuss pseudo-maximum likelihood estimation and present an application to recent elections in Italy. 相似文献
