It is generally considered difficult to resolve negative unidirectional externalities within hydro-hegemonic basins in which the upstream powerful riparian has the incentive to unilaterally develop the river without regard to downstream consequences. Weaker downstream riparian states can resort to issue linkages and side payments to coerce a change in the upstream hydro-hegemon’s behavior, but the success of these tools depends on the specific political and economic situation in the basin and on the preferences of the hydro-hegemonic state for cooperation. Neglected in the literature is another possibility. Through a consideration of the sanctioned discourse of watershed management at the domestic levels, this article shows that domestic environmental non-governmental organizations and policy entrepreneurs—through the application of a range of tools—can work to change the domestic water management discourse from a state-hydraulic paradigm to a more sustainable water management paradigm. When these efforts are successful, we can find that these non-state actors can perform a crucial function in cleaning up domestic stretches of international rivers, which produces positive externalities downstream. In the process, they are able of achieving what often years of international negotiations failed to accomplish. Drawing on semi-structured interviews, India’s policies on water quality in the national stretches of Ganges Basin and China’s policies on biodiversity in the national stretches of the Mekong Basin are used to make this argument. 相似文献

Intergroup Prejudice in Multiethnic Settings 总被引:7,自引:0,他引:7
This article examines how out-group perceptions among Asian Americans, blacks, Latinos, and whites vary with the racial composition of their surroundings. Previous research on the contextual determinants of racial attitudes offers mixed expectations: some studies indicate that larger percentages of proximate out-groups generate intergroup conflict and hostility while others suggest that such environments promote interracial contact and understanding. As most of this research has been directed at black-white relations, the applicability of these theories to a multiethnic context remains unclear. Using data that merge the 1992–1994 Multi-City Study of Urban Inequality and 1990 Census, we find that in neighborhood contexts, interethnic propinquity corresponds with lower levels of out-group prejudice and competition, although intergroup hostility is higher in metropolitan areas with greater minority populations. Further tests suggest that these results do not occur from individual self-selection; rather ethnic spatial and social isolation bolster negative out-group perceptions. These findings suggest the value of residential integration for alleviating ethnic antagonism . 相似文献

The results presented here suggest that Public Choice is broadly cited by economists and political scientists. The journal currently ranks, approximately, in the middle of the pack with respect to various citation measures. Also, since the late seventies, the journal's ranking has improved significantly relative to both social science journals and to comparable economics journals. Some of the papers published in Public Choice are well cited and several made a significant impact on the thinking of scholars in both economics and political science. Either through his work as editor or through his articles, the thought of Gordon Tullock is well represented in the elite group of articles published in Public Choice.The analysis of citations in Section 4 shows that Tullock's ideas and writing have had considerable impact on the thinking of economists. His contributions are substantial, often multi-disciplinary, and certain to be enduring. 相似文献

Stamp marks are used as a unique identification for a range of items, but these can be erased for criminal activities. Erased marks can sometimes be recovered by etching or magnetic means. The present study looked at the application of Fry's reagent to recover erased marks from steel. The investigation also demonstrated that Fry's reagent can deteriorate on storing and will require a longer etching time. The effect of different applied forces of stamping was investigated, and the depth of the underlying deformation was determined by etching after varying degrees of metal removal. The amount of metal needing to be removed depends on the force applied to the die. Metal removal also affects the time needed for recovery. The underlying structural change remains as a hidden identification mark, and could potentially be used by manufacturers as an unseen identifier. A model for the underlying deformation is proposed. 相似文献
