The concern driving current debate on agricultural extension is increasingly that of how to help farmers learn how to deal with the complex world around them responsibly and profitably, in such a way that the extension worker is ancillary. This article seeks to deconstruct and provide a more reasoned assessment of agricultural extension services through a reflection on development paradigms, adult education, individual empowerment, and institutional pluralism. By calling into question the underlying ethical dimensions of agricultural extension, it is possible to develop an alternative paradigm and thereby generate new insights into it. The article concludes that the raison d'être of agricultural extension today must be to create an ethical basis which ensures that extension practices are more inclusive and thus responsive to the needs of farmers and other rural populations, integrating individual expectations into the wider socio-economic, cultural, political, and geographical environment.  相似文献

The accountability of international development NGOs (INGOs) has attracted a great deal of interest from academics and development practitioners. INGO accountability falls into two categories: practical accountability (for the use of inputs, the way activities are performed, and outputs) and strategic accountability for INGOs' performance in relation to their mission. This article presents a conceptual framework for exploring INGO accountability. It is based on information collected through a literature review and semi-structured interviews with representatives from 20 UK-based INGOs. The research found that INGOs tend to use a number of quality-assurance mechanisms to achieve ‘practical’ accountability. However, it is suggested that this kind of accountability will not necessarily enable INGOs to achieve their missions to alleviate poverty and eliminate injustice. Furthermore, the predominant use of practical accountability has led to a number of gaps in INGO accountability. It is suggested that, like the term ‘participation’ before it, accountability has been co-opted for its instrumental benefits to INGO project performance and management. It is argued that if INGOs are to achieve their missions, this will require more ‘strategic’ forms of accountability, geared towards fundamentally changing those social, economic, and political structures that promote poverty.  相似文献

Corporate governance theory suggests that companies with dispersed and indirect ownership suffer from agency costs. A worst case is where several political authorities jointly own a company, which allows managers to operate with inferior efficiency. In political economy, the manager is not the major agency problem. Elected politicians may impair efficiency to improve their re‐election prospects. Since politicians have less influence in jointly owned firms, such companies are expected to perform better than those owned by a single public authority. Consistent with corporate governance – but not political economy – the empirical analysis suggests that dispersed municipal ownership impairs cost efficiency. In the Norwegian case of municipal refuse collection presented here, costs of dispersed ownership often outstrip gains from economies of scale. Use of jointly owned companies is not necessarily a proper response to efficiency problems inherent a fragmented local government structure.  相似文献

Using international data for 100 countries, we test two hypotheses derived from Bonger's Marxian theory of crime. The analyses support the hypothesis that the degree of capitalism significantly predicts homicide rates, but they fail to confirm that the de‐moralization of the population (loss of moral feelings for others) mediates the relationship between capitalism and homicide. Although capitalism is not the best predictor among those considered, overall, the results underline the importance of Bonger's ideas because both capitalism and corruption (our indicator of de‐moralization) show reasonably strong relationships with homicide rates and compete with other variables commonly used as predictors of international homicide rates. The results confirm the usefulness of attempting to subject Marxian ideas to positivist, quantitative tests, with an eye to integrating Marxian theories with other mainstream theories, such as institutional anomie theory.  相似文献
