The creation of new food sources is an important advancement in the search for solutions to food shortages in both developing and underdeveloped countries. Aquaculture, the production of aquatic animals under controlled conditions, offers exciting new possibilities for alternative protein sources in a wide variety of locales. This paper presents a mathematical programming model designed to aid the manager of an aquaculture facility in production scheduling and the evaluation of new technologies in this rapidly changing environment.  相似文献

The education of children living in out-of-home care (OOHC) has been a long-standing concern for children and their carers, policy-makers and researchers who have long highlighted the issue of low educational attainment and disengagement among children in care. This study investigates the strategies and practices used within a pilot programme based in the Northern Territory, Australia, that aims to re-engage children living in OOHC with education and training. Drawing on qualitative interviews with programme stakeholders, including educators, carers, child and family welfare workers, as well as an analysis of programme and client documentation, this study explores the programme's strategies to achieve re-engagement. The findings highlight the role of agile child-centred practice responding to the learning needs of participants, a focus on the ‘educational futures’ of students, as well as liaison and advocacy with schools and stakeholders on behalf of children in supporting re-engagement in education settings. Barriers to successful re-engagement include limited consideration of the cultural needs of children across education and OOHC systems, in particular the disruptive impact of OOHC placement changes, as well as programme discontinuity.  相似文献

Increasing attention is being paid to the economic sector known as the holistic milieu, in which alternative or New Age spiritualities are transformed into commercial products and services. Made up of a wide variety of activities and products, many marketized, this milieu is dominated by women as producers and consumers. The discourses of holism and wellbeing that underpin activity offer promises of gender equality and the freedom to develop subjectivity according to individual preferences. Despite its economic and cultural significance, little is known of why women in particular enter this sector. This article presents a critical realist analysis of how five women negotiated structural conditions and agency when leaving a mainstream occupation or organization to move into homeopathy, a key activity in the holistic milieu. I suggest that while there are numerous tensions and contradictions involved in this move, it is nonetheless a form of action that offers a different subject position and altered gender relations, based on embodied identity and exercise of agency. Whether the holistic milieu offers more equitable gender relations is less clear, but this seems less important for respondents than the other benefits the move implies.  相似文献

Although widely available, little is known about the effectiveness of youth cessation treatments delivered in real-world settings. The authors recruited a nonprobability sample of 41 community-based group-format programs that treated at least 15 youth per year and included evidence-based treatment components. Data collection included longitudinal surveys of youth participants (n = 878); posttreatment surveys of program leaders (n = 77); and one-time surveys of organizational leaders (n = 64)and community leaders in education, health, and juvenile justice (n = 94). Information about smoking-related ordinances was collected at the state and local levels. The framework, evaluation design, and implementation strategies described in this article provide a template for large-scale real-world program evaluations.  相似文献

This paper reports on a simulation study which was undertaken to determine if float could be significantly reduced by altering a bank's check-processing priority assignments. Float, the dollar value of check payments not yet collected from parent banks, represents a significant opportunity cost in terms of lost interest income to receiving banks. The study consisted of a comparison of a major city bank's present checksorting decision rules based on minimization of check handling, versus a proposed sorting scheme based on dollar magnitudes of checks. The reults of the research indicated that float could be substantially reduced and interest income increased by employing the proposed priority of scheduting rules.  相似文献

This paper presents a new model incorporating features of developing country agriculture likely to shape the welfare outcomes of alternative agricultural policies. The model features heterogeneous households linked through markets in a rural economy-wide structure, with endogenous market participation for farmers facing transactions costs. We use it to simulate the impacts on rural welfare of market price supports, production subsidies, input subsidies, and the removal of transaction costs. Applications to six countries demonstrate the diversity of potential impacts, exhibit some systemic differences compared with impacts in developed countries, and identify specific circumstances under which market interventions may be only slightly less efficient than direct payments at transferring incomes to rural households.  相似文献
