This study investigates the visual correspondences of gender posing behaviors, specifically exhibited by female figures, between historical European painting and contemporary American photographic advertising. While utilizing Erving Goffman’s Gender Advertisements as an analytical framework, the study focuses on the visual legacy of gender ritualization that is salient in contemporary mass media, proposing five semiotic codes to concretely analyze it. Although Goffman’s gender posing is traditionally associated with female vulnerability and indolence, the study proposes that such qualities are exploited as indicators of luxury within Western visual culture and advertising specifically. It seeks to deconstruct and re-frame the interconnected connotations of luxury and gender display, both expanding Goffman’s framework and providing a unique interpretive resource for critical readers of media texts.  相似文献

This paper discusses a novel strategy for simulating rare events and an associated Monte Carlo estimation of tail probabilities. Our method uses a system of interacting particles and exploits a Feynman-Kac representation of that system to analyze their fluctuations. Our precise analysis of the variance of a standard multilevel splitting algorithm reveals an opportunity for improvement. This leads to a novel method that relies on adaptive levels and produces, in the limit of an idealized version of the algorithm, estimates with optimal variance. The motivation for this theoretical work comes from problems occurring in watermarking and fingerprinting of digital contents, which represents a new field of applications of rare event simulation techniques. Some numerical results show performance close to the idealized version of our technique for these practical applications.  相似文献

The study proposes to individuate the relationship between social engagement, social statements and governance of SMEs. Does an adhesion to the philosophy and to the practices of CSR, which are reflected in a firm’s mission and accountability, positively influences its governance? If so, is this influence more or less significant for SMEs with respect to large-sized firms? This paper winds itself around these questions and describes the principle findings that have emerged from a qualitative investigation focused on a selected group of “cohesive” Italian SMEs, in which their management complies with both economic and social issues. The empirical study finds that the diffusion of CSR is tied above all to the entrepreneur’s values and orientation and to the company embeddedness to the local socio-economic environment. The concluding reflections trace the features of a territorial model of socially responsible orientation centered on the best practices of SMEs who are excellent examples of “spirited businesses” and are part of a network (which includes institutions, trade associations, non-profit organizations, etc.) that contributes to the diffusion of an orientation towards CSR and to sustainability across the territory.  相似文献

This paper examines the short and medium term impact of early childcare provision by grandparents and formal care settings on child cognitive outcomes, using data from the Millennium Cohort Study (UK). Compared with children placed in formal childcare, children cared for by their grandparents are better at naming objects, but perform worse on tests of basic concept development and non-verbal reasoning. These results mask strong heterogeneities. On the one hand, the positive association between grandparental care and child outcomes is stronger for children from more advantaged households; on the other, the negative association is only significant for those from more disadvantaged households. The results of OLS estimations used for our analysis are confirmed using panel methods and an instrumental variable approach.  相似文献

ABSTRACT In this paper we analyze the relationship between post-divorce private transfers (child support and alimony), mothers' economic independence and children's welfare using US data. Our empirical results show that mothers who receive child support and alimony from absent fathers are more likely to work and to spend a higher proportion of the income on child-related goods. We argue that the pattern of empirical results is consistent with there being significant externalities between parents even after divorce.  相似文献

Professional jazz has been organized around two contradictory cultures. Historically, the jazz art world has followed norms of meritocracy, which promote equality across boundaries of race and class. At the same time a culture of exclusivity, anchored in gendered essentialism, has severely limited female participation. By analyzing interview data with artists from the Hamilton College Jazz Archive, we illustrate how these contradictory cultures of inclusion and exclusion operate to channel women into feminized roles in the jazz world. We then discuss how women employ a number of strategies to work around the culture of exclusivity and capitalize on the norms and values of musical meritocracy. Despite institutional openings in professional jazz that emerged following the women’s movement, female jazz artists continue to face strong barriers toward full equality in the jazz world. Although female artists consistently demonstrate that they possess equal musical skills to male musicians according to the norms of meritocracy that guide professional jazz, women remain on the margins of the jazz art world.  相似文献

This study builds on research on the power of counter‐stereotypical cues, as well as intergroup contact theory, to consider whether interactions with a female teacher and female peers in a high school engineering classroom decrease male students' gender/science, technology, engineering, and math stereotypical beliefs and whether this varies according to the initial strength of their stereotypical views. Analyses reveal that among male students who initially reject stereotypes of male superiority, more female peers in the classroom leads to a further decrease in their stereotypical views by the end of the year. In contrast, boys who held strong stereotypical beliefs became less stereotypical by the end of the course when they had a female teacher. Implications for future research and current educational reforms are discussed.  相似文献

The accuracy of a binary diagnostic test is usually measured in terms of its sensitivity and its specificity, or through positive and negative predictive values. Another way to describe the validity of a binary diagnostic test is the risk of error and the kappa coefficient of the risk of error. The risk of error is the average loss that is caused when incorrectly classifying a non-diseased or a diseased patient, and the kappa coefficient of the risk of error is a measure of the agreement between the diagnostic test and the gold standard. In the presence of partial verification of the disease, the disease status of some patients is unknown, and therefore the evaluation of a diagnostic test cannot be carried out through the traditional method. In this paper, we have deduced the maximum likelihood estimators and variances of the risk of error and of the kappa coefficient of the risk of error in the presence of partial verification of the disease. Simulation experiments have been carried out to study the effect of the verification probabilities on the coverage of the confidence interval of the kappa coefficient.  相似文献
