A long-running debate about how voters use issues to evaluate candidates pits the proximity theory of voting against directional theory. Using surveys, both sides of the debate have found support for their preferred theory, but disagreement remains because of differing ways of analyzing the data. Lewis and King (2000) point out that these researchers make assumptions that bias results in favor of their theory. To avoid these difficulties, our approach creates fictitious candidates with controlled positions, presents these candidates to randomly-assigned subjects, and examines the relationship between subjects’ evaluations of these candidates and their ideological beliefs as a neutral test of proximity and directional theory. Our results provide reasonably strong support for proximity theory but little for directional theory. 相似文献

Foreign investment in agricultural land acquisition in sub-Saharan Africa has been viewed primarily as driven by a set of linked ‘crises’: in financial capital markets, in security of energy and food supply, and in global environmental governance. This paper argues that a focus on the ‘buyers’ of land risks overlooking the dynamics that operate on the side of the land ‘sellers’. Accordingly, the first part of the paper argues that it is important to view the current ‘land grab’ as the latest stage in a longer historical process of competition for control of land and other natural resources by different ‘domestic’ economic and political actors within African countries. While such struggles are often characterised as the ‘state versus the peasantry’, with the state acting on behalf of ‘urban elites’, the paper argues that processes of accumulation and associated enclosure of natural resources need to be examined more critically in specific contexts if the role and impact of foreign capital investment are to be understood. The second part of the paper seeks to identify the ways in which questions of scale (in the sense of greater capital intensity) can be considered to be constraints to the development of African agriculture. Particularly, it considers the extent to which the production models most frequently mentioned in connection with foreign investment (large-scale mechanised farms and small-scale outgrower contract farming) respond to current productivity constraints. The paper argues that current debates about foreign investment in agricultural land underplay the importance of water resources needed to overcome production risks associated with irregular rainfall. Bringing the water dimension of land deals more clearly into focus is necessary if the scope for positive and negative impacts of new investment on existing land users is to be fully understood. The paper concludes by considering the implications of such challenges in the current context of foreign investment in agriculture in Africa. 相似文献

Philip Alves 《South African Journal of International Affairs》2013,20(2):87-109
Ties between India and South Africa have grown rapidly over the past few years. But despite close collaboration on a range of issues and growing trade and investment ties, the relationship is a long way from reaching its full potential and there are still areas of difference between the countries. Philip Alves examines how the relationship has evolved historically, particularly since 1994, both politically and economically, and where it might be going. 相似文献
