We begin by definition of semi-Markov flow and discussion of its properties. Asymptotic behavior of multi-server and single-server queueing systems is studied under assumption of time-compression or service time growth. The results obtained are used for calculation of large systems reliability. Statistical estimates of parameters involved are also provided. 相似文献

选取浙江省杭州市20名创业女性为访谈对象的创业动机变迁研究显示,在2005年之前,女性创业动机以"推式动机"为多,而自2006年始,女性创业动机呈现出以"拉式动机"为主的趋势。这种变化主要与女性受教育程度提高、个性更为独立、追求更为自由的发展空间等相关。女性创业动机的变化趋势,在很大程度上反映了女性自我发展正趋向更高的水平。 相似文献

Unemployment among persons with disabilities is high. The situation is worse for women with disabilities as they experience multiple disadvantages on account of gender and disability. The condition for women with disabilities in Ghana could be more complicated, given the intersection of disability, gender, poverty, cultural beliefs and practices. As employment provides not only income for women with disabilities but opportunities for social participation and increases psychological well-being as well as self-esteem, it is imperative to remove barriers that hinder their employment. The current study examines issues associted with the unemployment of women with physical disabilities in Tamale, Ghana, and makes recommendations to policy-makers and practitioners in order to improve the condition of persons with disabilities in general, and particularly women with disabilities. 相似文献

This paper discusses the development of a children's rights‐based measure of participation and the findings from its use in a survey of 10‐ to 11‐year‐old children (n = 3773). The measure, which was developed in collaboration with a group of children, had a high reliability (Cronbach's alpha = 0.89). Findings suggest that children's positive experience of their participation rights is higher in school than in community, and higher for girls compared to boys. It is argued that involving children in the ‘measurement’ of their own lives has the potential to generate more authentic data on children's lived experiences. 相似文献

There are increasing numbers of families in Australia headed by sole parents, but little is known about the experiences of those who also care for a child with a disability. Additional caring responsibilities have previously been shown to impact on the work participation of parents. This study involved qualitative analyses of interview data conducted with sole mothers with school‐aged children with disability (N = 11). Thematic analysis revealed four themes that enabled and supported participation in the workforce: social support; managing appointments; characteristics of the workplace; and the role of the school. Results suggest the importance of practical help from family and friends in facilitating participation in paid employment. Additionally, the importance of flexible appointment scheduling on the part of service providers was highlighted, as well as the importance of workplace flexibility and supportive workplace cultures. Such factors were important in supporting sole mothers to balance work with care, with important implications for personal and family wellbeing. 相似文献

As female labor force participation increases globally, the relationship between maternal employment and children's development remains unclear. Using data from the India Human Development Survey (2005), we investigate the link between maternal employment and children's arithmetic and reading achievement. We develop a work pattern typology that goes beyond standard measures of employment and captures work intensity and its compatibility with child-rearing in a transitional economy. We find that the relationship between maternal employment and children's outcomes is not unidimensional. For example, children of self-employed mothers are not disadvantaged compared to those with stay-at-home mothers, but maternal employment in salaried jobs or wage work outside the home is negatively associated with cognitive skills in children. However, this negative association is reversed at higher levels of maternal education, suggesting greater access to resources and flexibility associated with better jobs mitigate the negative aspects of maternal employment posed by time constraints. Additionally, maternal employment is associated with maternal involvement in schoolwork and financial investment in academic activities, providing evidence that both time and resources devoted to children's education are significant. 相似文献

A challenge for large‐scale environmental health investigations such as the National Children's Study (NCS), is characterizing exposures to multiple, co‐occurring chemical agents with varying spatiotemporal concentrations and consequences modulated by biochemical, physiological, behavioral, socioeconomic, and environmental factors. Such investigations can benefit from systematic retrieval, analysis, and integration of diverse extant information on both contaminant patterns and exposure‐relevant factors. This requires development, evaluation, and deployment of informatics methods that support flexible access and analysis of multiattribute data across multiple spatiotemporal scales. A new “Tiered Exposure Ranking” (TiER) framework, developed to support various aspects of risk‐relevant exposure characterization, is described here, with examples demonstrating its application to the NCS. TiER utilizes advances in informatics computational methods, extant database content and availability, and integrative environmental/exposure/biological modeling to support both “discovery‐driven” and “hypothesis‐driven” analyses. “Tier 1” applications focus on “exposomic” pattern recognition for extracting information from multidimensional data sets, whereas second and higher tier applications utilize mechanistic models to develop risk‐relevant exposure metrics for populations and individuals. In this article, “tier 1” applications of TiER explore identification of potentially causative associations among risk factors, for prioritizing further studies, by considering publicly available demographic/socioeconomic, behavioral, and environmental data in relation to two health endpoints (preterm birth and low birth weight). A “tier 2” application develops estimates of pollutant mixture inhalation exposure indices for NCS counties, formulated to support risk characterization for these endpoints. Applications of TiER demonstrate the feasibility of developing risk‐relevant exposure characterizations for pollutants using extant environmental and demographic/socioeconomic data. 相似文献

Interactive Computer Based Instruction (CBI) systems involve teaching strategies to facilitate greater response opportunities during training in an effort to improve learner performance. The current study investigated the effect of online staff training videos with and without overt response requirements on posttest and maintenance test scores across six block-randomized instructional modules for four employees of a university located in the southeastern region of the United States. The overt response consisted of multiple-choice questions administered throughout select teaching modules using an alternating treatment design. Findings suggest that learning occurred as a result of the CBI training; however, the effectiveness of the overt response system varied across individuals, with no discernible differentiation between learning gains associated with response requirements. Other areas of research for expanding the efficacy of CBI and overt response systems are highlighted. 相似文献

AbstractThis article responds to the call for producing activist-oriented scholarship by engaging with theoretical and methodological approaches that explore the inclusion of women and girls with disabilities in Vietnam. We consider possibilities for connecting different forms of knowledge and activism by reflecting on research practices designed to foster social change. Specifically, we ask: how can critical disability studies be more reflexive about knowledge which privileges particular ways of knowing from the Global North? What alternative possibilities can exist to foster more inclusive and transformative knowledge that tackles systemic forms of oppressions in colonial and postcolonial contexts? Reflecting on an ongoing collaborative project in Vietnam, we argue that critical disability studies which engages with different forms of activism through critical reflections on our privileges can tackle exclusion by opening a new platform for debating social justice transnationally. 相似文献

This paper reports on qualitative research investigating the advice giving behaviours of social work students. Second-year students, who were enrolled in an interpersonal communication skills course, were required to undertake an ‘advice-giving audit’ exercise across 6 days, with the aim of strengthening their awareness of the interactive nature of advice giving. Students then wrote a diary entry about the frequency of their everyday advice giving behaviour, its intent and reception. Nineteen students provided these reflections for analysis. Findings included three themes pertaining to advice-giving: (i) Giving advice as a natural, comfortable and unconscious way of communicating; (ii) Power and position influences advice dissemination, and (iii) Withholding advice opens, deepens and confuses norms of communication. A fourth theme pertained to the insights that students reported from engaging with the exercise. These findings illustrate the complex interactional process associated with professional advice giving. The research also suggests that experiential activities, which are conducted outside of the classroom, have significant potential to promote the critical examination of embedded communicative practices. 相似文献
