‘Twinning’ is the distinctive method employed during the last two decades by the Swedish International Development Co‐operation Agency (Sida) to promote institutional capacity building in development co‐operation. This article reports on a study undertaken to provide evidence which would help Sida to make judgements about the efficacy of the twinning model as a basis for sustainable capacity building, and to explore ways of enhancing the method. The study indicates that the twinning method has potential advantages over other modes of development co‐operation, particularly that it offers enhanced possibilities for organizational learning and sustainable capacity building. However, the study suggests that this potential is not being fully exploited. Twinning arrangements have produced major benefits in professional/technical upgrading, but there is less evidence of outcomes at the level of sustainable institutional capacity building. Contrary to Sida's expectations of its distinctive advantages, in operation, twinning tends to become a rather routine process, viewed by developing country partners as an unexceptional way of delivering aid which presents few fundamental challenges and provides essentially the same benefits as alternative methods. It appears that institutional development and organizational learning are generally not issues of major significance for partner organizations in twinning arrangements. Even at the individual level the focus is on training rather than learning, which results in the usual emphasis on formal off‐job training rather than seeking opportunities for learning from work. The article presents ideas on how the current twinning approach might be renovated, and considers how agencies such as Sida might enhance their development co‐operation in the realm of governance by moving beyond twinning.

The concept of the circular economy is gaining momentum within the business world, and it is seen as an important element in the transition to a more sustainable future. Circular economies are built around a range of activities that look to reduce the demand for raw material inputs and natural resources and to recover, recycle, and reuse those inputs and resources as an integral part of the production process. As such, the concept of the circular economy restorative and regenerative and is contrasted, by its proponents, with the traditional “linear economy” that turns raw materials into waste in the production process and that is seen to lead to environmental pollution and the removal of natural capital from the environment. This commentary paper outlines the characteristic features of the concept of the circular economy, outlines how a number of companies are adopting circular economy approaches, and offers some general reflections on the application of the concept.  相似文献

Analysis of international alliances is often premised on predicted responses by nation states when nation states are assumed to behave as utility-maximising actors. ‘Large’ allies are exploited by ‘small’ allies when output is a public good. Empirical analysis of defence expenditures in NATO yields results consistent with the proposition that ‘exploitation’ increases as alliance output approximates a pure public good. But why would large countries acquiesce? A public choice analysis offers a different perspective. If producers of armaments are rent seeking, are large allies able to capture rent by incurring a disproportionate share of defence expenditure?  相似文献
