Two strategies for implementing a competency-based course in home economics education were compared. Sixty-three senior students were alternately assigned to a teacher-directed or student-directed class for attainment of specified competencies. Nine modules were developed to be used in the student-directed class and as the basis for instruc tion in the teacher-directed class. Criterion tests measured the extent to which compe tencies were attained for each group, and a Likert-type scale indicated students' attitudes toward competency-based education. Data were also analyzed to determine if student teach ing affected achievement of competencies. No significant difference in gain scores appeared between students who achieved com petencies through the student-directed and teacher-directed methods except in the competency area of program planning involving state standards. Significantly higher gain scores were attained by students who took the course before student teaching as opposed to those who took the course after student teaching in the competency areas of personal man agement, teaching skills, and motivation. No significant differences were found in gain scores between students who took the course before and after student teaching in the com petency areas of evaluation, departmental management, unit planning, program stan dards, or professionalism. No significant difference was found in attitude scores between individuals in the student-directed and teacher-directed sections.  相似文献

The first part of this article shows that in actual practice technology assessment (TA) has clearly moved from its basic conception as a set of objective methodologies developed and used by experts, to a standpoint which increasingly recognizes the need to make room for public participation. This has led to a view of controversies as informal processes of TA. The second part of the article argues for a further step, namely to conceive of TA as a social proces taking place in a space largely defined by controversies. Correlatively, it provides some initial elements for an analytical understanding of controvtersies as the ‘limiting factor’ of TA.  相似文献

In Vietnam, a quasi-private property regime has been established in 1993 with the issuance of exchangeable and mortgageable long-term land use right certificates. Using primary qualitative and quantitative data collected in a mountainous district of Northern Vietnam, this paper investigates the role of the land policy in the adoption of soil conservation technologies by farmers. This issue is of crucial importance in the region where population growth and growing market demands have induced farmers to intensify agricultural production. While poverty has been reduced, environmental problems such as soil erosion, landslides, and declining soil fertility have become more severe over the past years. Our findings suggest that despite farmers’ awareness of erosion, soil conservation technologies are perceived as being economically unattractive; therefore, most upland farmers continue to practice the prevailing erosion-prone cultivation system. Focusing on agroforestry as one major soil conservation option, we estimate household and plot-level econometric models to empirically assess the determinants of adoption. We find that the possession of a formal land title positively influences adoption, but that the threat of land reallocations in villages discourages adoption by creating uncertainty and tenure insecurity. The analyses reveal that these two effects interact with each other but are of small magnitude. We conclude that the issuance of land titles is a necessary but not sufficient prerequisite to encouraging the adoption of soil conservation practices. However, current practices remain economically unattractive to farmers. This deficiency needs to be addressed by interdisciplinary research and complemented by strong efforts by local authorities to promote sustainable land use.  相似文献

The pension systems in both Germany and Austria have undergone substantial reforms, though only one of the countries appears to have had success. Average earners in Austria will receive gross pensions equivalent to 78.1% of their average earnings, whereas in Germany they will receive just 37.5%. The authors argue that Germany has been left with a system that has abandoned the goal of protecting people's standard of living.  相似文献

The objective of this paper is to analyze policy design for air pollution management in the spatial context of urban development. We base our analysis on the paper of Ogawa and Fujita (Reg Sci Urban Econ 12:161–196, 1982), which offers a proper theoretical framework of non-monocentric urban land use using static microeconomic theory where the city structure is endogenous. First, we show that when households internalize industrial pollution in their residential location choice, spatialization within the city is reinforced. This impacts directly the emissions of greenhouse gases from commuting. Then, we analyze policy instruments in order to achieve optimal land use pattern when the policy maker has to manage both industrial and commuting related polluting emissions, that interact through the land market.  相似文献

The global economic downturn has forced many companies to reevaluate how they do business, in an aggressive effort to cut costs. Budget cuts are reaching 5 to 10 percent or more—and no part of a company is left untouched. But how can companies slash information technology costs and still maintain the same level of production? Here's one interesting strategy: use trained enterprise resource planning students, or TERPS. © 2009 Wiley Periodicals, Inc.  相似文献

This paper reports on the development of a smartphone app designed to give drivers and managers in a charity organisation greater visibility of transport, donation bank and shop stock in time and space. Trials of the app with samples of drivers and shop managers across three counties in the UK showed that users' understanding of vehicle activity and how time was utilised in the business was enhanced. The app also informed their decision-making, aided some collaboration and helped in their understanding of donation bank and shop performance, with one region altering their collection schedules. The quality of 3G signal was an issue in certain areas which impeded performance and the rules by which the messaging platform should be used in such a tool need careful consideration.  相似文献

This study investigates how the quality of stocks owned by mutual funds affects the performance of those funds during 2000–2009. The quality of a stock is positively related to its size, while quality is inversely related to volatility. Evidently, stocks in the lowest quality decile perform particularly poorly amidst volatile market conditions with a mean monthly Daniel, Grinblatt, Titman and Wermers (DGTW) alpha 1.93% [25.73% per annum (pa)] less than high‐quality stocks. Furthermore, funds which hold the lowest quality stocks exhibit substantial underperformance, particularly during market downturns, with funds in the lowest decile of quality incurring a mean monthly DGTW alpha 0.96% (12.14% pa) lower than their higher quality counterparts. Interestingly, we discover a trend to funds investing in higher quality stocks over time.  相似文献
