Abstract

This study examines the electronic availability of agronomy journals at eight ARL (Association of Research Libraries) member institutions with doctoral programs in agronomy. Of the forty-seven journals examined, twelve were not available electronically at any of the institutions. On average, institutions provided access to thirty of the titles, with twenty-seven of these being unembargoed. In terms of depth of access, much of the older literature which is important to the agricultural sciences was not available electronically. Librarians can use these results to communicate to researchers the importance of not relying solely on electronically available research materials.  相似文献

This study examines whether there were significant changes in the entry of young women to trade training in South Australia as a result of equal opportunities policies and initiatives to change the means of entry to trade training. It surveys the period 1981 to 1984 because that, like the present, was a period of change in education and training arrangements. It looks at women's hold on places in pre-vocational courses and apprenticeships in the most male-dominated trade areas and examines in detail the outcomes of the first three Introduction to Trades for Young Women courses in 1982 and 1983. It concludes that they led to only a slight improvement in female participation in trade training. The difficulties these courses faced in articulating with both student income support policies and the selection procedures for pre-vocational courses are discussed. The study demonstrates a marginal increase in the numbers of female apprentices outside hairdressing between 1981 and 1984 and evidence of weak commitment to an effective equal opportunities policy. A brief comparison is made between the situation at the beginning and end of the decade. This suggests that female participation in the most male-dominated trades areas in South Australia was generally lower than the Australian average in those areas, an outcome which must open to question the policy commitment to change.  相似文献

There are a disproportionate number of professional women working through temporary agencies. We develop a theory wherein this gender skewness in temporary-agency employment results from the differences in perceptions of control at work between men and women working through large traditional organizations. Our theory suggests that if control is perceived to be less for women than for men in large organizations, then women will tend to populate other work arrangements, like temporary agencies, in order to enhance their control. Propositions are tested via a unique data set comparing the responses of employees from both a London temporary accountancy agency and a large London accountancy firm. Our results are consistent with a lack of control driving professional women from large firms to temporary agencies, and neither rely on preference differences nor familial obligations.  相似文献

Public risk perceptions of mass disasters carry considerable influences, both psychologically and economically, despite their oft‐times imprecise nature. Prior research has identified the presence of an optimistic bias that affects risk perception, but there is a dearth of literature examining how these perceptions differ among cultures—particularly with regard to mass disasters. The present study explores differences among Japanese, Argentinean, and North American mental health workers in their rates of the optimistic bias in risk perceptions as contrasted between natural disasters and terrorist events. The results indicate a significant difference among cultures in levels of perceived risk that do not correspond to actual exposure rates. Japanese groups had the highest risk perceptions for both types of hazards and North Americans and Argentineans had the lowest risk perceptions for terrorism. Additionally, participants across all cultures rated risk to self as lower than risk to others (optimistic bias) across all disaster types. These findings suggest that cultural factors may have a greater influence on risk perception than social exposure, and that the belief that one is more immune to disasters compared to others may be a cross‐cultural phenomenon.  相似文献

This paper explores some aspects of the relation between aggregation and deliberation as ways of achieving a consensus amongst a group of indviduals on some set of issues. I argue firstly that the framing of an aggregation problem itself generates information about the judgements of others that individuals are rationally obliged to take into account. And secondly that the constraints which aggregation theories typically place on consensual or collective judgements need not be consistent with the outcomes of rational deliberative processes driven by individuals’ attempts to update on this information. The paper focuses on the particular case of allocation problems, for which there are established results both in aggregation theory and deliberation theory, to make this claim.  相似文献

Abstract

Addressing the intersection of two important emerging research areas, re-distributed manufacturing (RDM) and the food-energy-water (FEW) nexus, this work combines insights from engineering, business and policy perspectives and explores opportunities and challenges towards a more localized and sustainable food system. Analysis centred on two specific food products, namely bread and tomato paste reveals that the feasibility and potential of RDM vary with the type of food product and the supply chain (SC) components. Physically, energy efficiency, water consumption and reduction of waste and carbon footprint may be affected by scale and location of production activities and potentials of industrial symbiosis. From the business perspective, novel products, new markets and new business models are expected in order for food RDM to penetrate within the established food industry. Studies on policies, through the lens of public procurement, call for solid evidence of envisioned environmental, social and economic benefits of a more localized food system. An initial integrated framework is proposed for understanding and assessing food RDM and the FEW nexus.  相似文献

Scientists, activists, industry, and governments have raised concerns about health and environmental risks of nanoscale materials. The Society for Risk Analysis convened experts in September 2008 in Washington, DC to deliberate on issues relating to the unique attributes of nanoscale materials that raise novel concerns about health risks. This article reports on the overall themes and findings of the workshop, uncovering the underlying issues for each of these topics that become recurring themes. The attributes of nanoscale particles and other nanomaterials that present novel issues for risk analysis are evaluated in a risk analysis framework, identifying challenges and opportunities for risk analysts and others seeking to assess and manage the risks from emerging nanoscale materials and nanotechnologies. Workshop deliberations and recommendations for advancing the risk analysis and management of nanotechnologies are presented.  相似文献

Failure modes and effects analysis (FMEA) is a methodology for prioritizing actions to mitigate the effects of failures in products and processes. Although originally used by product designers, FMEA is currently more widely used in industry in Six Sigma quality improvement efforts. Two prominent criticisms of the traditional application of FMEA are that the risk priority number (RPN) used to rank failure modes is an invalid measure according to measurement theory, and that the RPN does not weight the three decision criteria used in FMEA. Various methods have been proposed to mitigate these concerns, including many using fuzzy logic. We develop a new ranking method in this article using a data‐elicitation technique. Furthermore, we develop an efficient means of eliciting data to reduce the effort associated with the new method. Subsequently, we conduct an experimental study to evaluate that proposed method against the traditional method using RPN and against an approach using fuzzy logic.  相似文献

This study adopts a qualitative approach to deconstruct the meaning of followership. Interviews were conducted with employees in various industries to examine how individuals socially construct their roles as followers and to explore followership schemas and contextual influences that relate to these constructions. Results suggest that while some individuals socially construct definitions around passivity, deference and obedience, others emphasize the importance of constructively questioning and challenging their leaders. With regard to personal qualities that are thought to make followers effective, major themes such as obedience, expressing opinions, and taking initiative were found to be most disparate across different groups of followers. Results also revealed that contextual factors may affect both followership constructions and behavior in the follower role. These findings have important implications regarding a need to examine the construct of followership in leadership research, as well as raise interesting possibilities for advancing an “expanded” view of leadership in organizations.  相似文献

Federal initiatives since 1996 have intensified the efforts of states to achieve adoption for children in foster care. For many waiting children, the path to adoption is long. The authors offer an economic analysis of adoption from foster care, with an emphasis on the reasons why achieving the goal of adoption for all waiting children may be so difficult. The authors then estimate the determinants of adoptions from foster care across the states using data for fiscal years 1996 and 1997. Adoption assistance subsidy rates stand out as the most important determinant of adoptions from foster care, followed by use of alternatives (e.g., intercountry adoption). Adoptive matching on the basis of race does not appear to prevent adoptions from foster care in the aggregate, leaving flaws in the matching process, such as a lack of information and difficulty using the Interstate Compact on the Placement of Children (ICPC), as a primary reason why children wait.  相似文献
