The use of the herbal stimulant khat (Catha edulis FORSK) is maintained by immigrants from countries where it is part of their cultural life (Arabian Peninsula and eastern Africa). In western countries the drug and its effects are largely unknown and no experience in evaluating impairment symptoms due to the khat-alkaloids, e.g. cathinone, cathine and norephedrine exists. Blood and urine samples from khat users involved in 19 cases of suspected driving under the influence of drugs were analysed and correlated with the results of medical examination and police officer reports. In 3 cases impaired driving and in 10 cases marked impairment of psychophysical functions was observed such as effects on the nervous system (slow pupil reaction to light, dry mouth, increased heart-rate), trembling, restlessness/nervousness, daze/apathy/dullness, impairment of attention, walking and standing on one leg. However, the alkaloid concentrations assayed in blood did not correlate with the impairment symptoms. Apart from an acute phase of indirect sympathomimetic action the development of habituation and withdrawal symptoms must also be considered in explaining the diversity of effects observed. From these results it can be concluded that chewing khat may severely impair driving ability, but may also be without noticeable effects. 相似文献

La notion d’arbitraire s’est imposée en théorie du droit—où il est question des moyens d’éviter l’arbitraire du juge ou du souverain—et en sémiotique, où la thèse de l’arbitraire du signe est associée à Saussure, un des pères de la “sémiologie”. Pourtant, aucune définition positive n’existe de l’arbitraire, ou du moins aucune ne s’est encore valablement imposée. Le présent article se propose de trouver les raisons pour lesquelles un concept si présent dans la théorie pâtit d’un tel manquement. 相似文献

This article discusses the meaning of self-determination in its historical and contemporary contexts and examines the different options available for the accommodation of contested self-determination claims. Among these, the creation of a new state, arguably, is the most radical of options and one that has significant regional and global implications beyond the territory to which it is applied. Detailing these implications in relation to the case of Kosovo, we make a broader argument that, even if secession is one mechanism to resolve self-determination disputes, this does not do away with the need to continue exploring settlements short of secession as alternatives to changing established international boundaries. 相似文献

AbstractThis article discusses the evolution of government-nonprofit relations at the regional level in Russia against the background of national-level restrictions on NGOs. Russia recently also introduced supportive policies and the article aims to trace the regional administrations’ reactions to the dual realities of the federal government’s posture towards nonprofits. Considerable variation was found in regional government-nonprofit relationships as well as deviation from national policy stances. Using a subnational comparative framework, this article addresses a gap in the literature and lays the groundwork for future cross-national comparisons of subnational variations of government-nonprofit relations in other authoritarian and hybrid political regimes. 相似文献

Transformational and transactional leadership strategies have become prominent in public administration research, but it is unclear whether they are compatible or whether they could undermine each other. We examine the combined and interactive effects of transformational and three types of transactional leadership (contingent verbal rewards, material rewards, and sanctions) on employee work motivation, conceptualized as work engagement and intrinsic motivation. Panel analyses using repeated measures of 385 leaders and 3,797 employees show that transformational leadership and contingent verbal rewards increased employee motivation. However, simultaneous use of contingent material rewards undermined the benefits of transformational leadership. Thus, the motivational potential of service‐ or community‐oriented visions was undercut when leaders also appealed to extrinsic material motives. This could help explain why financial incentives do not always have the expected benefits in public organizations. We therefore argue that research and practice should pay more attention to how different leadership strategies work in combination. 相似文献

This paper provides a narrative account of the Swiss environmental foreign policymaking process by former Swiss government officials and links their observations to relevant foreign policy and international relations theories. It provides background information on the broader context for sustainable development contained in the new Swiss Federal Constitution and suggests how realigning government, economy and society on the new Federal Constitution can help to promote sustainable development domestically and through multilateral channels. 相似文献
