This study investigates the relationship between direct democracy and political trust. We suggest a solution to the controversy in research centering on positive versus negative effects of direct democracy by analytically differentiating between the availability of direct democratic rights and the actual use of those rights. Theoretically, greater availability of direct democratic rights may enhance political trust by increasing citizens' perception that political authorities can be controlled as well as by incentivizing political authorities to act trustworthily. In contrast, the actual use of the corresponding direct democratic instruments may initiate distrust as it signals to citizens that political authorities do not act in the public's interest. We test both hypotheses for the very first time with sub‐national data of Switzerland. The empirical results seem to support our theoretical arguments. 相似文献

The dramatic growth in the relationship between Africa and China is one of the great stories of the twenty-first century, part of the profound transformations taking place in the global political economy. It has been greeted with excitement, consternation, and confusion. To its cheerleaders, it represents the enduring partnership between Africa and China, spawned by the historical affinities of struggles against Western imperialism and humanistic aspirations for development. To its critics, it is reminiscent of European colonisation a century earlier, in which Africa serves as a cheap source of raw materials, a lucrative export market for Chinese manufactured goods, and an outlet for its surplus capital. Rather than a development partner, some see China as Africa's biggest development competitor, whose explosive growth and insatiable quest for global markets threatens Africa's industrialisation and competitiveness. This paper examines the factors behind the development of Africa-China relations, especially its economic magnitude, and the challenges and opportunities it offers both regions. 相似文献

ABSTRACTA significant proportion of critical agri-food literature has, to date, focused on the uneven relations of power between the Global North and the Global South, and the neoliberal characteristics of the corporate food regime. This literature has often overlooked the nuances in varieties of capitalism, particularly in East Asia. China is re-emerging as a powerful state actor in an increasingly multipolar global food system. It is also an important hub of capital, facilitating agribusiness mergers and acquisitions, as well as new East–South and South–South flows of agri-food trade, technology and capital. This paper aims to contribute to understanding state-led capitalism in China and neomercantilist strategies in the agri-food sector. The paper provides a critical analysis of a case study of China's state owned agri-food and chemical companies ‘going global’. It contends that the current food regime is in a period of transition or interregnum – a period of fluidity separating the continuity of successive regimes. Arguably, the analytical contours of a contemporary food regime in transition cannot be adequately comprehended without recognising the incipient importance of state-led capitalism and neomercantilism, and how contemporary socio-political and economic dynamics are reshaping relations of power in the global political economy of food. 相似文献

AbstractGlobal, national and local policies and programmes for agricultural development are recurrently justified based on their alleged role in improving food and nutrition security. However, strikingly little evidence is available to prove that a direct, household-level link between agricultural production and improved nutrition exists. The objective of this special issue is to systematically and empirically test, using data from Africa and South Asia, whether a relationship between household agricultural production and nutrition can be found. Overall, the studies in this special issue support the hypothesis that household agricultural production has direct and important linkages with dietary patterns and nutrition. 相似文献

As the Soviet Union disintegrated and eventually dissolved in 1991, many of its peoples, both so-called titular nationalities and national minorities, put forth demands for independence or, at the very least, self-rule for territories that were said to represent the national patrimony. Among the many peoples who put forward such demands were Carpatho-Rusyns, who, together with fellow citizens of other national backgrounds, demanded autonomy or self-rule for the region (oblast) of Transcarpathia in far western Ukraine. This essay examines from a historical perspective the question of autonomy or self-rule for Carpatho-Rusyns and for all or part of the territory they inhabit, historic Carpathian Rus’. The autonomy question in Carpathian Rus’ is hardly new, but one that goes as far back as 1848. 相似文献

This study presents a number of pseudo-operational trials on plastic bags investigating the double- and co-fuming process of a one-step fluorescent cyanoacrylate (LumicyanoTM) in comparisons with the two-step process with basic yellow 40 (BY40) staining for the detection of latent fingermarks. The results demonstrate that both Lumicyano solution and dye contribute to the increased detection of latent fingermarks during the double-fuming process (trial 1). Co-fuming the Lumicyano solution and dye separately (at a concentration of 8%) but simultaneously was less effective than 8% Lumicyano (trial 2). Co-fuming Lumicyano 8% and an additional 8% Lumicyano dye by weight was more effective than Lumicyano 8% (trial 3), possibly due to increased fluorescent material deposition during co-fuming allowing for better visualization. The use of BY40 after Lumicyano resulted in a considerable increase in detected fingermarks. 相似文献
