This case study exploits matched firm–employee Tunisian data in order to underline the role played by within-firm human capital in worker remuneration. The estimated returns to human capital in wage equations remain unchanged when the dummies representing firm heterogeneity are replaced in the list of regressors with three firm variables: a textile industry dummy, within-firm mean education, and firm age. We find that part of what is usually considered as return to education may be due to within-firm externalities.  相似文献

Numerous studies document sex differences in African American girls’ and boys’ academic achievement and motivation, but little is known about how the enactment of gender, such as in the forms of gendered behaviors, attitudes, or personal-social qualities, is related to school functioning. To advance understanding of African American adolescents’ academic experiences, this study examined the longitudinal linkages between stereotypically feminine (i.e., expressive) and stereotypically masculine (i.e., instrumental) personality characteristics and school adjustment. The moderating effects of youth’s ethnic identity and school racial composition also were tested. Participants were 352 African American youth (50.1% girls; mean age at Time 1?=?12.04 years; SD=?2.03) who participated in annual home interviews. Net of biological sex, expressive traits (kind, sensitive) were positively related to school self-esteem and school bonding for both girls and boys, but youth with higher levels of instrumentality (independent, competitive) exhibited sharper declines in academic achievement across adolescence. School racial composition moderated the effects of instrumentality at the between-person level, such that instrumentality was positively related to school self-esteem only for youth who attended schools with fewer African American students. These results highlight the importance of incorporating gendered personality traits, rather than biological sex alone, into theoretical accounts of African American youth’s school functioning.

This paper examines British women's accounts of buying and wearing lingerie taken from in-depth interviews exploring experiences of shopping in sex shops. Lingerie forms one part of a sexual consumer culture that is positioned within a neoliberal discourse of postfeminism. Women's engagement with the representation of lingerie, the way they enact lingerie buying and wearing in their everyday lives and the ways they speak about these practices show complex and often incongruous strategies of accommodation and negotiation. Such strategies can make lingerie pleasurable and liveable whilst at the same time expressing forms of anxiety, ambivalence or laughter directed towards the performance of femininity and feminine sexuality required and represented by lingerie. I contend that it is precisely through this often contradictory engagement with lingerie that strategic counter discourses emerge, by which women can resist some of the respectable norms of female sexuality. Women position themselves in ambivalent ways in relation to the visual imperative of feminine sexuality represented by lingerie, particularly through an embodied discourse of comfort and discomfort, or through the playful and pleasurable performance of non-naturalised gender roles.  相似文献

The article argues that explanations of problematic governance are institutional rather than organizational and have their roots in the deep structures of society. Bangladesh is used as an exemplar for such analysis, deploying the notion of the institutional responsibility square comprising four institutional domains of state, market, community and household. A prior or ‘total institution’ metaphor is used to describe the ways in which different classes are obliged to pursue their livelihoods, entrapped within the problematic social embeddedness of these four institutional domains. The article develops this argument via three themes: permeability between these domains (i.e., blurred moral boundaries between public and private behaviour); problem of legitimation of public institutions, given this permeability; and the incorporated rather than independent characteristics of civil society, thus limiting optimism about its potential to create reform. Nevertheless the article offers a strategic agenda of institutional improvement (i.e., escape from the prison) based on the principles of shifting people's rights from the problematic, uncertain informal sphere towards the formal realm.

The present work empirically analyzes diverse budgetary theories (incrementalism, garbage can, rational) in municipal cost programs, paying special attention to the utility of financial information in decision making. The sample analyzed corresponds to a set of Spanish city councils in the period 1996–2004, and the econometric methodology used is a dynamic panel data model. The main conclusion reached is that the budgetary allocation of municipal costs does not follow a random path; incrementalism is of particular importance, together with financial information variables. The utility of budgetary indicators is reflected in the fact that municipal managers adopt rational elements, although incrementalism remains the habitual behavior.  相似文献

In November 2018, Butte County, California, was decimated by the Camp Fire, the deadliest wildfire in state history. Over 150,000 acres were destroyed, and at its peak, the fire consumed eighty acres per minute. The speed and intensity of the oncoming flames killed scores of people, and weeks before the fire was contained, first responders began searching through the rubble of 18,804 residences and commercial buildings. As with most mass disasters, conventional identification modalities (e.g., fingerprints, odontology, hardware) were utilized to identify victims. The intensity and duration of the fire severely degraded most of the remains, and these approaches were useful in only 22 of 84 cases. In the past, the remaining cases would have been subjected to conventional DNA analysis, which may have required months to years. Instead, Rapid DNA technology was utilized (in a rented recreational vehicle outside the Sacramento morgue) in the victim identification effort. Sixty-nine sets of remains were subjected to Rapid DNA Identification and, of these, 62 (89.9%) generated short tandem repeat profiles that were subjected to familial searching; essentially all these profiles were produced within hours of sample receipt. Samples successfully utilized for DNA identification included blood, bone, liver, muscle, soft tissue of unknown origin, and brain. In tandem with processing of 255 family reference samples, 58 victims were identified. This work represents the first use of Rapid DNA Identification in a mass casualty event, and the results support the use of Rapid DNA as an integrated tool with conventional disaster victim identification modalities.  相似文献
