Current theoretical understanding of compliance with international law is based on an assumption that international law consists of a finite set of objective, compulsory rules. This image does not match reality but the two can be reconciled through theorising international law as ideology. Such an approach subsumes questions as to why states do or do not obey law and what influence international law has on foreign policy decision making. By placing the relationship of state behaviour to international law in a broader perspective it can account for previously identified determinants of compliance and provide a basis on which to assess their relative significance. At the same time, the research agenda regarding compliance is broadened by the introduction of fresh questions. 相似文献

Abstract. In the text some questions about the genesis of radical nationalism on the former Yugoslav territory are discussed. The author's main thesis is that what happened during the outburst of nationalism was an alteration in the status of national identification, particularly in its relation to ‘supranational’ Yugoslav identification; that is, the eruption of radical nationalism was the result of reorganisation within an identification matrix. This thesis is first clarified by a short historical survey of the status of national identification before the outburst of nationalism, and secondly by an analysis of the main changes in the identification matrix during the outbreak of nationalism. Additionally, some of the main characteristics of political socialisation in the Yugoslav socialist state (especially the function of the value ‘brotherhood and unity’), as well as the possibility for future non-conflictual relations between the nations of former socialist Yugoslavia are discussed. 相似文献

ABSTRACT. Total cleared area in a von Thünen land-use model drives an atmosphere externality which depresses agricultural productivity uniformly throughout the region. Exogenous events that encourage clearance and use of a larger cultivated area (output price or population increase) exacerbate the externality. Imposition of a simple, corrective tax on land rents does not reverse these patterns but does mitigate the increase in the externality and leaves cultivators with higher incomes than they would obtain without the tax. We examine an optimal tax on land rents, designed to maximize the social value of land rents in the region, and an output tax. 相似文献

High-precision neutron activation measurements have been made on mesoamerican obsidian from Ixtepeque and El Chayal which are thought to be the major sources of volcanic glass artifacts in pre-Columbian times. These results are compared with measurements on obsidian artifacts from Lubaantun, Wild Cane Cay, Frenchman's Cay and Moho Cay. 相似文献
