As part of the European project, Impaired Motorists, Methods of Roadside Testing and Assessment for Licensing, otherwise known as IMMORTAL (Deliverable R4.2), the University of Glasgow was required to analyse 1396 oral fluid samples, collected from drivers, for a wide range of drugs. A previously described method to include 49 drugs and metabolites was used. To include cannabis in the study a separate extraction method was required because of interferences caused by the collection device. The study group included drivers who were stopped at random and participation was entirely voluntary. The results showed that out of the 1396 samples tested, 16.8% were positive for at least one drug. In the majority of positive cases (85%), monodrug use was found and the most commonly detected drug was 3,4-methylenedioxymethamphetamine. This study showed that a significant number of the driving population are positive for at least one drug.  相似文献

Conclusion Technological progress always contains within it the ironic dialectic of liberation and domination. The computer-based information highway is no exception. As a consequence, our own view is that the computer revolution contains the potential for both over-control and subversion of control. Science and technology are not neutral. They are social constructs that exist only within a context of choices of development and application. Therefore, it is not the technology that constrains, or oppresses, or liberates. Rather, the emancipatory potential of this new technology lies in the degree to which those who use it can disseminate it and maintain it as a relatively low-cost communication tool. To date, many of those involved in expanding the Internet frontier have generally been suspicious of and resistant to government intrusion into the Net. While it is often easier to simply dismiss such suspicion as the ranting of conspiracy theorists, history has taught us that such a na?ve faith in the benevolence of the government is unwise. Our intention here has not been to provide a definitive conclusion about the past, present, or future state of technological progress; instead we hope that our discussion will spark further critical analysis of technology and related topics.  相似文献

Russia started its decollectivisation effort in earnest after the abortive 1991 coup attempt. A legislative foundation has been laid and over one‐quarter million peasant farms have been created, many through the act of exiting a collective by a farm worker, taking his or her land and asset shares along. Yet significant obstacles remain in the path of both continued peasant farm creation and the viability of those already functioning.  相似文献

Abstract

In January 1974, when fighting broke out between Saigon forces and Chinese in the oil-promising South China Sea, the American establishment news media tended to assume that the Chinese, being communists, must have been the aggressors. Those reporters who were quickly able to attune themselves to the official State Department line, however, refrained from making any judgment regarding the merits of the controversy. And well they might have, for the assertions of America's client regime regarding the various archipelagoes are at best dubious. Official U.S. Government maps designate the islets by their Chinese (not Vietnamese) names, and neither Hanoi nor the Provisional Revolutionary Government has stated any claims in the region.  相似文献

In this article, the process of social reproduction has been analyzed in Lorca, a municipality in the western Mediterranean region of Murcia (Spain) at the end of the 18th century. An exhaustive subset of the data from the local Godoy's census (1797) was used consisting of 29,875 individuals living in a total of 7566 households. This population was distributed between the town, the Huerta (the Murcian irrigated market garden community), and the countryside. Results confirmed, on the one hand, that a direct relationship existed between higher social status and size of household, with a higher number of older children in the households of land-owning farmers than of tenant farmers or day workers. More children in higher status households indicate that children left home later, and therefore inheritance problems rose, which influenced social reproduction within these groups. Spatially, a clear division can be found between the countryside with more male work-hands and a higher index of male activity and the Huerta with a certain female dominance.  相似文献

This essay seeks to identify relevant issues regarding the relationship between organizational change strategies aimed at improving the delivery of public services to low income clientale in human service agencies. * *A human service is defined as a form of assistance given to a client by a public agency; such assistance i s ameliorative in nature and is intended to provide for a social welfare need that cannot otherwise be met. *A human service is defined as a form of assistance given to a client by a public agency; such assistance i s ameliorative in nature and is intended to provide for a social welfare need that cannot otherwise be met.$ef: The strategies discussed in this

essay are: organizational development (OD), transorganizational development, reorganization and decentralization. The discussion is mainly theoretical, derived only in part from the literature and from actual experiences. The focus i s on detemining (logically, not empirically) the consequences of applying different types of organization change strategies as means for improving the delivery of human services. A major assumption i s that each of the strategies would incur somewhat different costs and produce different benefits with varying operational constraints.  相似文献

ABSTRACT

In 1966 the UN passed two International Human Rights Covenants that are among the great achievements of humankind. The covenants were adopted in five equally binding languages, one of which was Chinese. The People's Republic of China (PRC) is generally assumed to have ratified one and signed (but not ratified) the other. In 1973, however, soon after the PRC began representing China in the UN, new Chinese-language versions of each mysteriously came into existence. These are the versions one is likely to find on the UN website, and they are what the Chinese government treats as the “covenants.” The authors of this article show that these contain substantial revisions from the covenants that had been passed by the UN 1966 and subsequently ratified by at least 164 countries. The revised versions are so different, in fact, that one could well question whether the PRC actually embraced either covenant. The covenants granted rights that the revisions would later withdraw, and in at least one case the revisions recognize a right that is absent in the covenants. Based on their comparative analysis of the various versions, the question arises as to whether China is a responsible actor in the international legal order and a reliable partner when it comes to entering into agreements with other countries or acceding to international treaties. Given that China comprises over one-fifth of humanity, it also brings into question whether the principles in the covenants can claim absolute validity and anything like universal acceptance.  相似文献

Correspondence     
The origins of the Anglo-American intelligence relationship are usually dated to the early years of the Second World War. This article suggests that the First World War interaction between the intelligence staffs of the British and American Expeditionary Forces was a significant precursor to the emergence of the later relationship. Using primarily American archival sources, the article reveals an intimacy that emerged in the summer of 1917 and continued, to a lesser extent, until the armistice. The emergence of this close relationship is attributed to a common language, independent-minded intelligence leaders, and an element of chance.  相似文献
