A previous study conducted in 1995 showed that psychoactive drug use by workers was higher in safety/security workstations than in the rest of the labour force. In order to verify this finding, we conducted a new study in 2003-2004 in the Nord-Pas-de-Calais region, restricted to truck drivers. The aim of this study was to allow harmonizing the professional practice of the occupational physicians, proposing drug prevention and drug testing policies, validating the analytical methods and the guidelines in case of positive testing results. One thousand truck drivers were studied. Urines were tested for amphetamines, cannabinoids, cocaine, opiates, benzodiazepines, buprenorphine and methadone by immunoassay. Urine ethanol determinations were performed by an ADH method. Positive urines for drugs of abuse, methadone or buprenorphine were then tested by gas chromatography or liquid chromatography coupled to mass spectrometry. Out of the 1000 drivers, cannabinoids were detected in 85 cases, opiates in 41 cases, amphetamines in 3 cases and cocaine in only one case. Buprenorphine was detected in 18 cases, methadone in 5 cases and benzodiazepines in 4 cases. Urine ethanol was positive in 50 cases. We found only one case with 6-monoacetylmorphine. Other positive opiates were metabolites of antitussives. The relatively low number of benzodiazepine positive urines could be explained by the lack of sensitivity of the test we used. All these results confirm those of the previous study for cannabinoids and ethanol in safety/security workstations. Positive results for methadone and buprenorphine are eight times higher than in the general population. In conclusion, the authors think that it will be of a great interest to test urine of truck drivers for other classes of psychoactive drugs, using a liquid chromatography-mass spectrometry method. 相似文献

In many countries, local government size is increasingly thought to be insufficient to operate efficiently. Two possible solutions to this problem are amalgamation and intermunicipal cooperation. This paper applies a novel methodology to shed light on the efficiency implications of this choice. Using a unique and rich micro-level dataset, we find that intermunicipal organisations (IOs) in the Netherlands consistently pay higher interest rates than municipalities, while there is no economic reason to do so. We interpret this as a form of inefficiency. Municipal amalgamation, on the other hand, does not result in higher interest rates. Our analysis eliminates one possible explanation, dispersed ownership of IOs, as the number of partners cooperating in an IO does not affect interest rates (no ‘law of 1/n’). This leaves the introduction of extra hierarchical layers as a result of cooperation, and the ensuing reduction in monitoring, as the most probable explanation. 相似文献

Sommaire. L'auteur, après avoir décrit la nature du gouvemement local, son rǒle, sa fonction ainsi que son financement, s'interroge sur le type de gouver-nement local souhaité. Il opte pour un gouvemement local autonome dont le rǒle principal est de fournir des services à la propriété et aux personnes. Cette identification des rǒles permettra d'orienter les sources de revenue en référence avec les fonctions municipales. Selon cette hypothèse, l'impǒt sur le revenu comme source de financement municipal ne semble pas approprié. Il serait préférable d'améliorer la performance de l'impǒt foncier et trouver d'autres sources de taxation rattachées soit à la propriété, soit à la prestation des services. De měme, l'intervention des gouvemements provinciaux et fédéral doit ětre limitée si l'on ne veut pas que les municipalités deviennent des administrateurs de programmes provinciaux et fédéraux. Abstract. This paper, after reviewing the nature of local government, its role, its function as well as its funding, speculates as to the proper type of local government. He favours an autonomous local government whose main function would be to supply services to property and individuals. This role identification would allow to gear income sources to municipal functions. Under this policy, an income tax considered as the source of municipal funding would not seem suitable. It would be better to improve the performance of the real estate tax system and to find other sources on the basis of either ownership or supply of services. The intervention of provincial and federal governments should also be curtailed to prevent municipalities from becoming the administrators of provincial and federal programs. 相似文献
