Adoption of new technology in peasant agriculture remains lower than expected. Failure to achieve expected returns is associated more with insufficiencies in the conduct of research than with external and economic factors such as price structure or lack of agricultural support services. This article sets out the case for national agricultural research and extension structures that emphasize on-farm research with a systems approach. 相似文献

In this article two problems with the recently developed "practice or virtue approach" to business ethics are discussed. The first problem concerns an alleged harmony between common demands of morality (generally understood) and the internal goods of actual business practice. The claimed harmony is strong in essence since it holds that the role expectations a good manager has to live up to, do in fact coincide with what morality demands. The second problem is related to the first and concerns the alleged relevance of a virtue perspective for business ethics. According to the virtue perspective discussed in this article, moral reasoning should take actual practice, and only actual practice, as a point of departure. In so doing ethics is claimed to become insulated from e.g. putting irrelevant demands on practitioners. Such demands are understood as based on abstract principles alien to the practice in question. The thesis of this article is that neither of the above mentioned two claims are plausible. This is so basically because one needs to turn elsewhere than to actual business practice in order to detect a morally laden notion of managerial goodness. 相似文献

What is the impact of patent citations on patent renewal behaviour? Patent citations are commonly used as an indicator of technology spillovers. For cited patents, therefore, patent citations have a potentially ambiguous impact. On the one hand, patent citations may indicate a scientific breakthrough, a high value of the cited patent and therefore a long survival period. On the other hand, patent citations may indicate competing innovations that render the cited patent obsolete. By discriminating patents by technology field, it is demonstrated that patents that receive citations across technology fields survive longer than other patents. Patents that receive citations within the same technology field lapse earlier. 相似文献

We compare two different models for assets and liabilities for an insurance company that can be considered in the standard approach to solvency assessment and in particular, in determining the required target capital. The first model is suggested by a joint working party by members in CEA, Comité Européen des Assurances, and is based on the duration concept and the second one is an application of ideas by Samuelson and Vasicek. 相似文献

Documentation and analysis of prevention goals and interventions employed by community-based injury prevention programmes is vital to advance the knowledge and understanding of synergistic multi-strategy injury prevention programmes. This study examined the goals and interventions of 25 Scandinavian community-based injury prevention programmes in WHO-designated Safe Communities. Collection and analysis of quantitative data from survey questionnaires to the programme coordinators was followed by collection and analysis of qualitative data from structured interviews with programme coordinators from eight of the programmes. The results demonstrated that the programmes under study predominantly relied on "intuitive" and subjective methods for selecting interventions. The programmes largely failed to transform injury surveillance data into information and knowledge that could prioritize community safety strategies and measures, due to insufficient time and personnel resources. The results demonstrated the importance of combining passive approaches with active interventions. Educational efforts were considered essential to the programmes. The programmes preferred to rely on broadly stated goals rather than specific objectives. 相似文献
