There is an increased awareness that the performance of boards (good governance) is not only determined by structural determinants but by behavioral determinants as well. These behavioral determinants might be particularly important for public and nonprofit governance, where the role of the board is more diffuse and heterogeneous than in corporate governance. Here we investigate how social dynamics within boards in secondary education influence their performance. We follow a concise model that includes cognitive conflict, the use of expertise, effort norms, and social cohesion as determinants of board task performance. A survey among all secondary schools in the Netherlands serves as the empirical underpinning for this process‐oriented model of good governance. We show that the behavioral determinants have different effects on the control task and advice task of boards. Also, we find that cognitive conflicts in supervisory boards do not lead to less but rather to more social cohesion within boards. Building on these findings, we suggest a revised model of the behavioral determinants of nonprofit board performance. 相似文献

The stand-up comedy landscape has been transformed in recent years with an increased number of disabled comedians performing. Using semi-structured interviews with disabled comedians, this article provides a thematic analysis of the material and ideological motives, intentions and lived experiences of disabled comedians. Two themes are discussed: comedy management and control; and affirming disability through comedy. These themes are characterised by complexity and contradictions. The article concludes that, although not a straightforward process, stand-up comedy enacted by disabled comedians is potentially a powerful tool through which hegemonic norms around disability can be challenged and renegotiated. 相似文献

The journey out of care and towards independent living is a challenge for many care-leavers. There has been little research into the social processes involved in this care-leaving journey. This paper presents the results of a grounded theory investigation into the care-leaving journeys of nine young men who had, several years previously, been in the care of Girls & Boys Town in South Africa. Working from a resilience perspective, with an ecological emphasis, four central social processes emerged that together explain the care-leaving experiences of the participants. These processes are striving for authentic belonging; networking people for goal attainment; contextualised responsiveness and building hopeful and tenacious self-confidence. These four processes are located within contextual boundaries and at the social environmental interface. The paper presents these processes in detail, drawing on selected narratives of the participants and integrated with additional theory. It is hoped that this paper may contribute to theory building concerning care-leaving processes and enhance youth care practices for youth in care and leaving care. 相似文献

We address ethical consumption using a natural field experiment on the actual purchase of Fair Trade (FT) coffee in three supermarkets in Germany. Based on a quasi-experimental before-and-after design the effects of three different treatments – information, 20% price reduction, and a moral appeal – are analyzed. Sales data cover actual ethical purchase behavior and avoid problems of social desirability. But they offer only limited insights into the motivations of individual consumers. We therefore complemented the field experiment with a customer survey that allows us to contrast observed (ethical) buying behavior with self-reported FT consumption. Results from the experiment suggest that only the price reduction had the expected positive and statistically significant effect on FT consumption. 相似文献

Background
The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.Objectives
The aim of this project is to determine, assess and identify the real impact of breastfeeding support networks in Murcia (Spain).Methods
After searching unsuccessfully for a validated questionnaire, a specific one was developed and validated for measuring the impact of formal and informal support networks through five dimensions: satisfaction, consultation, experience, problems and support. The questionnaire was provided to 500 mothers with experience in breastfeeding, who brought their children to baby paediatricians between 2 June and 27 November 2014. Upon completion of the survey and fieldwork, a detailed statistical analysis was conducted.Results
The degree of satisfaction perceived by the users of the services of support breastfeeding networks is remarkable. In addition, mothers who clarified their doubts and discussed their problems with health professionals and/or breastfeeding support networks were more likely to breastfeed for a longer duration compared to those who did not (p = 0.005). Furthermore, mothers who sought support in breastfeeding are more likely to breastfeed for more than 6 months (p < 0.0005).Conclusion
Based on this information, we conclude that breastfeeding support networks have a positive influence in the duration of a women’s decision to breastfeed. 相似文献108.

We review theorizations of gendered anti-Blackness and the scholarship on the politics of belonging. Bridging together this literature, we propose gendered anti-Black non-belonging as an alternative framework for addressing African descendant women's expressions and realities of belonging in the United States and Portugal. We select these two cases for their remarkably distinct—yet related—racial ideologies of the state. In the United States, colorblindness is the main ideology of the state whereas in Portugal anti-racial ideology pervades. As we will highlight, the experiences of belonging among African descendant women in the United States and Portugal challenge the veracity of these racial ideologies which work to render gendered anti-Black oppression invisible. In both cases, anti-Black non-belonging means that African descendant women are vulnerable to gendered state violence and racist practices impacting their individual and group belonging; as a result, the right for Black bodies to be in a particular place and space is constantly contested, and, often, violently regulated and disciplined. Yet, anti-Black belonging is both a matter of oppression and resistance. African-descendant women draw from their everyday knowledge of domination to employ resistance. In doing so, as we will argue, they rewrite the national narrative of race, gender and belonging in Portugal and the United States. 相似文献

For many environmental processes, recent studies have shown that the dependence strength is decreasing when quantile levels increase. This implies that the popular max‐stable models are inadequate to capture the rate of joint tail decay, and to estimate joint extremal probabilities beyond observed levels. We here develop a more flexible modeling framework based on the class of max‐infinitely divisible processes, which extend max‐stable processes while retaining dependence properties that are natural for maxima. We propose two parametric constructions for max‐infinitely divisible models, which relax the max‐stability property but remain close to some popular max‐stable models obtained as special cases. The first model considers maxima over a finite, random number of independent observations, while the second model generalizes the spectral representation of max‐stable processes. Inference is performed using a pairwise likelihood. We illustrate the benefits of our new modeling framework on Dutch wind gust maxima calculated over different time units. Results strongly suggest that our proposed models outperform other natural models, such as the Student‐t copula process and its max‐stable limit, even for large block sizes. 相似文献
