This study investigates the experiences of lesbian and gay parents seeking health care for their children within the Australian medical system. Previously unavailable demographic data was collected on lesbian and gay families, and qualitative information was sought from parents about positive or problematic health care experiences related to sexual orientation and family constellation. Ninety-two lesbian or gay parents responded to a national postal and Web-based survey. Eighty-nine percent of respondents reported a high level of satisfaction with the health care received by their children. Despite overall satisfaction, however, 49 percent of parents identified fear of disclosure of sexual orientation, and 27 percent reported negative or problematic experiences with their children's health care related to sexual orientation or family constellation. This study indicates that fear of discrimination and homophobic attitudes towards lesbian and gay families remain a factor within the Australian health care system.  相似文献

Parallel individual and ecological analyses of data on residential radon have been performed using information on cases of lung cancer and population controls from a recent study in south-west England. For the individual analysis the overall results indicated that the relative risk of lung cancer at 100 Bq m−3 compared with at 0 Bq m−3 was 1.12 (95% confidence interval (0.99, 1.27)) after adjusting for age, sex, smoking, county of residence and social class. In the ecological analysis substantial bias in the estimated effect of radon was present for one of the two counties involved unless an additional variable, urban–rural status, was included in the model, although this variable was not an important confounder in the individual level analysis. Most of the methods that have been recommended for overcoming the limitations of ecological studies would not in practice have proved useful in identifying this variable as an appreciable source of bias.  相似文献

Many retail product returns can be refurbished and resold, typically at a reduced price. The price set for the refurbished products affects the demands for both new and refurbished products, while the refurbishment and resale activities incur costs. To maximize profit, a manufacturer in a competitive market must carefully choose the proportion of returned products to refurbish and their sale price. We model the sale, return, refurbishment, and resale processes in an open queueing network and formulate a mathematical program to find the optimal price and proportion to refurbish. Examination of the optimality conditions reveals the different situations in which it is optimal to refurbish none, some, or all of the returned products. Refurbishing operations may increase profit or may be required to relieve a manufacturing capacity bottleneck. A numerical study identifies characteristics of the new product market and refurbished products that encourage refurbishing and some situations in which small changes in the refurbishing cost and quality provoke large changes in the optimal policy.  相似文献

The possibilities which information and communication technologies (ICT) offer people (or groups) to overcome the friction of distance and the constraints of materiality mean that these technologies are seen to have particular relevance in rural areas which have been historically characterised in terms of their economic and social perpheriality. In this paper, we draw on empirical research with children and their teachers and parents, to explore the opportunities which ICT are seen to offer young people living in rural areas. First, we examine the information that children access on-line and how young people make sense of this expanded terrain. Second we focus on communication, by considering children's use of email and chat rooms. Third, we explore how this information and these modes of communication may be shaping young people's sense of place in the world. Our findings expose a clear contrast between the ambitious and future orientated ways in which adults imagine ICT will expand their children's educational and employment opportunities, and social and spatial horizons, and the everyday ways in which these technologies actually emerge for children in practice.  相似文献

There is consensus that the effective implementation of cross-functional teams is critical to new product success. However, such teams face particular challenges because of well-documented barriers between functions. Furthermore, there is little evidence-based guidance for practitioners on how to achieve effective cross-functional teamwork. In order to address this gap, the literature on cross-functional teamwork was analysed to identify critical success factors. Using a heuristic team effectiveness model, these were categorized into six groups: task design, group composition, organizational context, internal processes, external processes and group psychosocial traits. Recent theory on group effectiveness has increasingly recognized the significance of a supportive organizational context, and this is particularly pertinent for cross-functional teams. Key success factors include strategic alignment between functions, a climate supportive of teamwork and team-based accountability. The findings are integrated into a diagnostic model which is intended to be of practical benefit to people designing, leading and facilitating cross-functional new product development teams.  相似文献

Open innovation and absorptive capacity are two concepts based on the idea that companies can leverage the knowledge generated externally to improve their innovation performance. The aim of this paper is to analyse the joint effect of open innovation and absorptive capacity on a firm's radical innovation. Open innovation is expressed in terms of external search breadth and depth strategies and absorptive capacity is described by distinguishing between potential and realized absorptive capacity. In order to test our hypotheses, we carried out empirical research in firms operating in high-technology industries. The results indicate that internal routines and processes for absorbing external knowledge help explain radical innovation as they show a significant effect of potential and realized absorptive capacity. Also, there is a moderating effect of absorptive capacity on open innovation. Specifically, potential absorptive capacity exerts a positive effect on the relationship between external search breadth and depth and radical innovation. Realized absorptive capacity moderates the influence of external search breadth. These findings confirm the complementary nature of absorptive capacity and open innovation search strategies on radical innovation.  相似文献

Sociological theory suggests two reasons that volunteering runs in families. The first is that parents act as role models. The second is that parents who volunteer pass on the socioeconomic resources needed to do volunteer work. Panel data from two generations of women (N = 1,848) are analyzed to see how much influence family socioeconomic status and mother's volunteering have on daughter's volunteer careers. More highly educated women and women whose mothers volunteered donate more hours initially, but only family socioeconomic status increases volunteering over the life course.  相似文献

This article draws upon research with men and women workers in ‘flat’ organizations, namely mixed-sex and all-women's worker co-operatives and collectives in the voluntary sector. It argues that the denial of sales, contracts and grants to women's co-operatives and collectives in particular, can be connected to discourses of sexuality generally and to the assumptions surrounding lesbianism and separatism in particular. Such discourses are often used to marginalize women workers and their co-operatives and collectives, irrespective of whether the women in such organizations are lesbians or not. It is argued that when women workers organize in ways which challenge male-dominated hierarchy, their marginalization necessarily takes a sexualized form because organizations, whether hierarchical or less/non-hierarchical, are not only gendered but are also sexualized. This analysis thus offers an important additional dimension to the view that the marginalization of co-operatives and collectives is due to their small size, lack of capital, location in certain sectors of the economy, or assumptions concerning the ‘alternative’ or ‘fringe’ nature of employment in such settings. This article also argues that sexuality can attach at the level of the organization, and not simply at the level of individual bodies or life-styles, an argument often unacknowledged both in the literature on lesbians in the workplace, and in the literature on co-operative businesses and less or non-hierarchical voluntary sector organizations generally.  相似文献
