The authors' goal was to characterize predictors of attitudes toward lesbian and gay parent families (LGPF), held by students enrolled in psychology, social work, medicine, nursing, elementary, and preschool education programs in Portugal. The authors examined the predictive value of students' (n = 600) sociodemographic characteristics when assessing their attitudes toward LGPF. Participant's gender, interpersonal contact with lesbians and gay men, gender role attitudes had indirect effects on attitudes toward LGPF, through attitudes toward lesbians and gay men. Understanding characteristics associated with attitudes toward LGPF may inform decisions in terms of the education and training of helping professionals. 相似文献

工业共生研究综述 总被引:2,自引:0,他引:2
张萌 《哈尔滨工业大学学报(社会科学版)》2007,9(4):97-102
工业共生作为工业生态系统的重要特征和实现途径已经引起学者们的关注。然而,目前工业共生的理论研究仍处于起步阶段,侧重于相关概念的阐释和理论平台的搭建,大致形成了工业共生链网结构、形成动因、网络治理和评价研究等几个方面。未来的研究应综合运用产业生态学、管理学、经济学相关理论及分析方法深入研究工业共生形成机理和稳定运行的规律性问题,由此为我国发展循环经济、建设生态工业园提供必要的理论支持。 相似文献

A quantitative microbial risk assessment (QMRA) according to the Codex Alimentarius Principles is conducted to evaluate the risk of human salmonellosis through household consumption of fresh minced pork meat in Belgium. The quantitative exposure assessment is carried out by building a modular risk model, called the METZOON-model, which covers the pork production from farm to fork. In the METZOON-model, the food production pathway is split up in six consecutive modules: (1) primary production, (2) transport and lairage, (3) slaughterhouse, (4) postprocessing, (5) distribution and storage, and (6) preparation and consumption. All the modules are developed to resemble as closely as possible the Belgian situation, making use of the available national data. Several statistical refinements and improved modeling techniques are proposed. The model produces highly realistic results. The baseline predicted number of annual salmonellosis cases is 20,513 ( SD 9061.45). The risk is estimated higher for the susceptible population (estimate 4.713 × 10−5 ; SD 1.466 × 10−5 ) compared to the normal population (estimate 7.704 × 10−6 ; SD 5.414 × 10−6 ) and is mainly due to undercooking and to a smaller extent to cross-contamination in the kitchen via cook's hands. 相似文献

This study investigated the monthly dynamics of social assistance benefit receipt – in particular the incidence of long‐term benefit receipt – in four European countries: Luxembourg, The Netherlands, Norway and Sweden. The analysis is based on four separate administrative panel data sets, each covering the 96‐month period from January 2001 to December 2008. Benefit dynamics were found to vary considerably across countries. In the two Nordic countries, long‐term benefit receipt was found to be a rare exception. Most recipients, however, had multiple spells and the majority of benefit leavers returned to benefits within a few months of leaving. In Luxembourg and The Netherlands, long‐term benefit receipt was frequent, but benefit leavers were much less likely to return to benefit receipt after exit. The total duration of benefit receipt per individual across spells was two to three times as high in The Netherlands and Luxembourg as in Norway and Sweden. 相似文献

Informed by abstract models of language change or stability over time, we present a longitudinal study of two African American females, first interviewed as teenagers, and re‐recorded twenty years later. As teenagers, they used morpho‐syntactic features of AAVE voraciously. But as working adults, these women distance themselves from their teenage activities and social networks, and display a considerably reduced vernacular usage that accords with their articulated concern to get ahead. The diachronic interpretation that best characterizes their transformation is age‐grading rather than generational change, since change at the individual level is accompanied by stability at the community level. The picture is complicated by intermediate recordings showing that one of the speakers is a stylistic chameleon, capable since her teenage years of varying copula absence rates depending on addressee, topic, and projected persona. But the age‐grading interpretation of change at the individual level remains valid based on the evidence of her reduced use of habitual be2, and third singular present tense –s absence. The case highlights the importance of paying more attention to stylistic variation and including more than two time points in sociolinguistic studies of change in real and apparent time. 相似文献

财政政策作为宏观经济政策体系中的一个重要内容,在战后日本经济增长中发挥了积极作用。而财政政策的中心目标,就是在高水平的就业基础上,保持经济稳定和稳步提高生产率,以在可用资源约束下实现最大化经济增长。文章以理论研究为主,以泡沫经济博奕现象分析为出发点,深入研究日本财政政策选择的最优次序和数量财政政策向质量财政政策转移问题,指出只有实行“质量扩张”财政政策才是经济稳定发展的必由之路。 相似文献
