This contribution considers an alternative approach to the research on the use of force, a field that has been largely dominated by international legal scholars. I argue for application of an evolutionary approach to international (legal) norms, one that complements current legal approaches and moves the discussion of norms beyond their dichotomous legal/illegal understanding. This kind of research highlights the role of politics in international law and allows us to determine factors influencing dissemination of international norms. Through a study of seven post-Second World War cases, I trace the development of both narrow and expanded notion of preemptive self-defence and conclude that while ascertaining legality of specific actions is vital for understanding established international law, one cannot talk about radical breaks in development of the law on the use of force. The expanded concept is in fact a product of the evolution of (societal) norms on self-defence and an accumulation of previous successful challenges in metanorms on the use of force.  相似文献

A recently completed survey of British manufacturing investment in 14 anglophone African countries indicates that there has been major disinvestment during the last five years. This process of corporate disengagement is occuring despite concerted attempts by African governments to improve the overall investment climate for both national and foreign investors. The article analyses the pattern of disinvestment by country and industrial sector and considers some of the key causal factors.  相似文献

This paper discusses the effect of the ruling by the European Court of Justice in the Bosman case which delivered freedom of contract to professional soccer players. The result is examined in the context of modern investment theory where contracts between club and player are considered as options to renegotiate the contract or to sell the player to another party. The effects of the ruling are reconsidered in this light and the reaction of the soccer world to these effects are discussed.  相似文献

It is widely recognized that interest groups affect both microeconomic and macroeconomic outcomes. However, few researchers have attempted to discern empirically the factors that contribute to interest group activity. This paper provides a test of several theories of group formation in a panel setting. A nation’s stability, socioeconomic development, political system, size, and diversity all appear to contribute to interest group formation, as predicted by theory.  相似文献

Parental reports of adolescent substance use were compared to the adolescents' self-reports using identical scales. Congruence was defined as exact agreement on whether adolescents were current users, ex-users, or never-users. Both parents were found to be less accurate in predicting their adolescents' alcohol use compared to cigarette or marijuana use. Single mothers were significantly less likely to be congruent than were mothers from two-parent households. Mother and father congruence on all substances was unrelated to the adolescent's sex, race, or after school employment. For both parents, congruence for adolescent marijuana use was significantly related to the age and GPA of the adolescent. Congruence may also reflect important properties of family functioning, as significant relations were found between both adolescent and parent ratings of family cohesion and parent-adolescent congruence on perceptions of marijuana use.This research was supported by Grant DA03706 from the National Institute of Drug Abuse (Hyman Hops, Principal Investigator).Jennifer Langhinrichsen is a doctoral candidate in psychology interested in adolescent and family interactions. The other authors are psychologists or data analysts working on family influences on substance use and mental health.  相似文献
