Different viewpoints were expressed at the 1990 annual national conference of the South African Society for Agricultural Extension regarding the role of extension in the development of the farmer as entrepreneur. It is expected that public funding will increasingly be limited to functions of general public interest. To achieve independence farmers should be willing to expose themselves to entrepreneur development stimuli. it is in the public interest to develop scarce human, economic and natural resources. Research findings indicate distinct behavioral differences between entrepreneurs of differing perceptions. A comprehensive interdisciplinary education is recommended for agriculturalists. Because needs change, education programmes must be re‐evaluated from time to time. It serves little purpose to educate people in extension who do not have a technical message to communicate. The state extension service seeks closer cooperation and liaison with agricultural co‐operative and private sector know‐how. Departmental policy will probably be less rigid in future.
A clear distinction should be made between information and extension services. The adoption of an ethical code for extensionists may be opportune. Relevancy is an important contributing factor to extensionist credibility. 相似文献

As a result of the productivity study in both areas, the following objectives can be attained: Ascertain the number of FTEs necessary for staffing requirements. Determine the efficiency level in daily production of trays and sets. Develop standards to measure the overall effectiveness in delivering service. Although this represents a quantitative analysis of the productivity within a CSS department, it is important not to forget the human element in the relationship between CSS and OR employees. 相似文献

The discussion of purchasing practices and product integrity, which have ethical implications for materiel/manufacturing management, serves to illustrate how routine decisions can have larger implications for the firm as a whole. Management needs to take a proactive role in confronting ethical issues by (1) demonstrating a corporate commitment to sound ethics in business practices, (2) providing written policies where appropriate to provide a basis for sound ethical conducts, (3) educating various functional areas to understand their responsibility in seeming unrelated ethical problems, (4) delegating authority in ethical issues where such issues are considered in decision making, and (5) fostering interfunctional communication as a means in establishing corporatewide responsibility. The basic philosophical principles of JIT serve as a blueprint for recognizing and managing ethical responsibility. The unexpected by-products of a JIT implementation may be vendor/customer good will and an excellent reputation for the firm. 相似文献

Developing and applying a framework to evaluate participatory research for sustainability 总被引:7,自引:0,他引:7
The normative implications of participatory research imply ongoing social learning that ought to lead to personal and institutional transformation. Sustainability science also requires reflexive scientific practice in order to enable the co-generation of solutions that take account of uncertainty and multiple forms of knowledge. However, there is little published peer-reviewed material on how to assess to what degree the rhetoric regarding the benefits of participatory research are achieved in practice, particularly with regard to participatory research for sustainability. This paper outlines how linking the rationales for participatory research and for sustainability science to the principles of evaluation can deliver a conceptually coherent evaluation framework for assessment. The approach for evaluating participatory research in this context consists of framing the evaluation, i.e., setting boundaries on the subject within its social, political, environmental and institutional context and selecting appropriate criteria, methods and data sources. The application of the framework, using a summative evaluation of participatory research for sustainability in north-east Australia, illustrates its strengths and weaknesses, concluding with a consideration of its applicability to further participatory sustainability science. 相似文献

Regional, national, and spatially explicit scenarios of demographic and economic change based on SRES 总被引:4,自引:0,他引:4
We report here spatially explicit scenario interpretations for population and economic activity (GDP) for the time period 1990 to 2100 based on three scenarios (A2, B1, and B2) from the IPCC Special Report on Emissions Scenarios (SRES). At the highest degree of spatial detail, the scenario indicators are calculated at a 0.5 by 0.5 degree resolution. All three scenarios follow the qualitative scenario characteristics, as outlined in the original SRES scenarios. Two scenarios (B1 and B2) also follow (with minor adjustments due to scenario improvements) the original SRES quantifications at the level of 4 and 11 world regions respectively. The quantification of the original SRES A2 scenario has been revised to reflect recent changing perceptions on the demographic outlook of world population growth. In this revised “high population growth” scenario, A2r world population reaches some 12 billion by 2100 (as opposed to some 15 billion in the original SRES A2 scenario) and is characterized by a “delayed fertility transition” that is also mirrored in a delayed (economic) development catch-up, resulting in an initially stagnating and subsequently only very slow reduction in income disparities. The spatially explicit scenario interpretation proceeds via two steps. Through a combination of decomposition and optimization methods, world regional scenario results are first disaggregated to the level of 185 countries. In a subsequent second step, national results are further disaggregated to a grid cell level, taking urbanization and regional (rural–urban) income disparities explicitly into account. A distinguishing feature of the spatially explicit scenario results reported here is that both methodologies, as well as numerical assumptions underlying the “downscaling” exercise, are scenario-dependent, leading to distinctly different spatial patterns of population and economic activities across the three scenarios examined. 相似文献

This paper examines the concept of sustainability and its implications for environmental policy analysis. It builds on the premise that present society holds a moral obligation to pass on a world of undiminished life opportunities to members of future generations. Maintaining life opportunities, in turn, can be achieved by maintaining or improving a diverse set of resources and capabilities that support a person's freedom to define and pursue her own conception of the good life. On an operational level, this framework points to the following guideline for environmental policy: Protecting the rights of future generations requires either the conservation of environmental resources or compensatory measures (including the provision of substitute technologies) that ensure the fair and proportionate sharing of net benefits over intergenerational time scales. In this framework, resource depletion is permissible only if (with reasonable certainty) it would generate a Pareto improvement relative to a baseline scenario involving strict resource conservation. 相似文献

This paper presents a broad diagnostic of the level of institutional development in Portugal in the legal, corporate governance and financial systems. A comparative assessment suggests that Portuguese institutions are less developed than their European Union and East Asian counterparts, more developed than Greek institutions and on a level similar to that of Spanish institutions. We use data for a wide cross-section of countries since 1960 and correlate indicators of institutional development with the long-term average growth rate, identifying issues where reform is likely to significantly affect economic growth. We construct three new indices that measure the potential of institutional reform - the impact of reform on growth, the required reform effort and the efficiency of reform index - by taking into consideration the institutional distance between Portugal and the European Union. These indices measure, respectively, which reforms have the most payoff in terms of growth, which are less costly to undertake and which deliver the most growth per required effort. Our results strongly suggest that in a large number of issues, institutional reform may translate into substantially higher rates of economic growth. Of the ten most promising reforms, six are in the legal area, irrespective of which of the indices is considered. Whereas legal reform is promising at the aggregate and the microeconomic levels, in the financial sector aggregate indicators offer the wider scope for productive reform, while in the corporate governance area it is indices at the micro level that hold the most promise. These results support the view that a comprehensive reform effort is likely to deliver higher rates of growth in Portugal, allowing faster real convergence with the rest of the European Union.Received: January 2003, Accepted: February 2004, JEL Classification:
