Classic studies on hegemonic stability and power transition suggest that concentration of capabilities favoring a single state can promote economic cooperation and discourage militarized conflict. However, tests of these arguments have been primarily limited to examining temporal variation in global capability distributions and corresponding levels of system-wide cooperation; few have examined the impact of capability concentration at the region level. In this article, we contend that concentration of regional military capabilities corresponds to lower trade costs for states throughout a region and to an incentive for weaker states to de-prioritize expenditure on the military, freeing resources that can be used to promote trade. As a result, this condition promotes higher levels of trade, particularly within the region. We also argue that democratic regional powers are better able to foster confidence in the sustainability of cooperation; thus, the trade-enhancing impact of concentrated regional capabilities is stronger when the predominant state is more democratic. We find evidence in support of our expectations in statistical models examining state trade between 1960 and 2007.  相似文献

This paper explores the relationship between ground rent, production and knowledge in Ecuador’s neo-structuralist, state-led project to transform the productive matrix. Based upon insights from the Marxian approach to the critique of political economy, we interrogate how neo-structuralism has conceptualised the relationship between ‘natural resource income’ and ‘knowledge-based’ economic development. The paper argues that a rent-theoretical perspective, which takes seriously the regional unfolding of uneven geographical development in Latin America, can highlight the limits of a national development plan conceived according to the logic of Schumpeterian efficiency. In doing so, the paper identifies the contradictory relationship between natural resource exports, state-led ‘knowledge’-based development and capital accumulation. On this basis the paper offers a historically and empirically informed critical analysis of selective import substitution industrialisation and vanguard science and technology strategies designed to transition Ecuador away from primary resource dependence.  相似文献

This article investigates how the introduction of new crops influences intra-household decision-making among the Ovambo in northern Namibia where women are responsible for crop farming, while men are engaged in livestock farming. It examines gender relations that underlie daily activities. The findings of the study show that women try new crops on their own or with the help of their children and do not negotiate with their husband, mothers, or brothers over household resources such as land, labour, and the cash of other family members. Women avoid conflicts with family members, but may have an increased perception of contribution to the household if they succeed in introducing new crops.  相似文献

This ‘Viewpoint’ assesses some recent approaches to the study of feminisms across the globe during the c. 1870–1930 period. At a moment when historians are working towards the commemoration of women's partial enfranchisement in Britain in 1918, we consider the intellectual frameworks that most effectively celebrate this achievement whilst also situating the Act within its complex, global context. Reflecting on discussions held at a recent workshop at the University of Oxford, we advocate the effectiveness of a global and comparative methodological approach to question what ‘feminism’ meant to contemporary campaigners. The scrutiny of localised and national issues within comparative and global contexts illuminates the plurality of definitions, vocabularies, and categories relating to feminism that were being used (and rejected) during this era and raises broader questions for the study and practice of feminist history.  相似文献

Although proprietary medicines and decoction of processed aconite roots are the most widely used, tincture accounts for the great majority of aconite poisoning cases in China, indicating that it is much more toxic than other formulations. Aconite tincture is often self-prepared at home and raw aconite plants or roots are often used. Even if processed aconite roots were used to make the tincture, the amount of Aconitum alkaloids is highly variable, depending on the adequacy of processing and quality control. Aconitum alkaloids dissolve efficiently in alcohol. For these reasons, tincture contains very high concentrations of Aconitum alkaloids. Despite its high intrinsic toxicity, overdose of aconite tincture by the users has been common. Severe aconite poisoning can be complicated by fatal ventricular tachyarrhythmias and asystole. The public should be repeatedly warned of the danger of taking aconite tincture by mouth.  相似文献

In China, urban middle class mobilization against potential pollution risk has become increasingly common. This article examines this phenomenon through a detailed case study of a 2009 anti‐waste incinerator campaign in the Panyu District of Guangzhou, which culminated in a sizeable public protest and government U‐turn. This episode revealed tension between the narrow, state‐centered regulatory model fixated on end‐of‐pipe pollution control, and a much broader decentered approach advocated – and practiced – by project opponents, which incorporated public consultation and much greater emphasis on upstream waste reduction and sorting. In the process, the Panyu campaign progressed beyond a case of “regulation by escalation,” whereby beneficial regulations are belatedly enforced following populist pressure. Instead, it transformed into an open dialogue between a plurality of actors, including citizens, journalists, experts, and officials, about what regulation should constitute and who should determine acceptable levels of risk. By focusing on the processes through which regulatory issues emerged and changed during the Panyu campaign, this article highlights the regulatory dynamism of environmental mobilization in a context of regulatory uncertainty, and campaigns against “locally unwanted land uses” more broadly.  相似文献
