Abstract: This article is intended to give an overview of the law as it stands on telecommunications at the Community level. Over the past ten years the telecommunications law and policy of the European Community have developed rapidly along the twin axes of liberalisation (deregulation) and harmonisation (reregulation). The innovative use of Article 90 EEC has been central to liberalisation, while most harmonisation legislation has been based on open network provision (ONP) passed under Article 100a. The article concludes that, now the national monopolies have been largely dismantled, new issues will arise in the competitive market. 相似文献

The U.S. incarceration rate rose dramatically over the past 45 years, increasing the number of marriages and cohabiting unions disrupted by a jail or prison stay. But as some have pointed out, not all unions dissolve as a result of incarceration, and there seems to be racial–ethnic variation in this tendency, with Blacks displaying higher rates of dissolution than Whites and Hispanics. Yet it is unclear what explains racial–ethnic differences in union dissolution among the incarcerated. Drawing on the National Longitudinal Survey of Youth 1997 (NLSY97), we examine why racial–ethnic differences in union dissolution exist among a sample of individuals who had a marital or a cohabiting union interrupted by an incarceration spell. In doing so, we draw on social exchange theory and structural and cultural theories to suggest that racial–ethnic disparities in union dissolution are explained by differential exposure to protective relationship characteristics. The results of Cox hazard models reveal that Blacks have significantly higher hazards of union dissolution than do Whites and Hispanics. These results also indicate that being married, having a child together, having full-time employment, a longer union duration, and a shorter incarceration spell may protect against dissolution and that these factors account, in part, for the greater risk of dissolution among Blacks relative to Whites and Hispanics. 相似文献

Psilocin (4-hydroxy-N,N-dimethyltryptamine, 4-HO-DMT) and bufotenine (5-hydroxy-N,N-dimethyltryptamine, 5-HO-DMT), which are both naturally occurring compounds, are classified as controlled substances in numerous countries due to their pharmacological activities and recreational usage. There are two other benzene ring regioisomers, 6-hydroxy-N,N-dimethyltryptamine (6-HO-DMT) and 7-hydroxy-N,N-dimethyltryptamine (7-HO-DMT), which are not classified by name as controlled substances, and which were synthesized for this current work. The four isomers were analyzed using routine methodologies employed by the Israel's Police Division of Identification and Forensic Science (DIFS) Laboratory, namely thin layer chromatography (TLC), Fourier transform infrared spectroscopy (FTIR), and gas chromatography mass spectroscopy (GC-MS). It was found possible to differentiate the four isomers. Forensic specimens that were suspected to be psilocybe mushrooms were examined, confirming that it is now possible to unequivocally identify the presence of psilocin and rule out the presence of its other isomers. 相似文献

What kind of thing is the economy, and how might we act to change it? This article draws on the work of Timothy Mitchell and J. K. Gibson-Graham to suggest that the economy may be fruitfully understood as a structural effect, or an appearance of difference maintained through the repetition of acts and practices. It then employs Reinhart Koselleck’s theory of conceptual change to argue that the economy effect may be altered through efforts aimed at conceptual innovation. If the economy effect is maintained through repeated acts and practices that delineate the distinction between the economy and everything else, then conceptual innovation with respect to those concepts that inform these acts and practices could alter the manner in which this distinction is produced. The benefit (or public interest) corporation serves as an example of how such efforts at conceptual innovation might produce change in the structural effect that we call “the economy.” 相似文献

This article argues that the efforts of policy‐makers to avoid conflict in the short run can be counterproductive in the long run. Not only may policy‐makers fail to reap the benefits of conflicts when they try to steer clear, but conflict may actually increase rather than diminish. We study conflict through the conceptual lens of (de)politicization in the lengthy and highly contested policy‐making process over the multibillion‐euro ‘Oosterweelconnection’ highway in Antwerp (Belgium). An in‐depth media analysis of 739 articles is combined with data from 32 narrative interviews. We conclude that efforts to end public debate through depoliticization can have a boomerang effect, in which conflict disappears only temporarily, and that these efforts can ultimately increase conflict while wasting engagement and creativity. More attention to the productive aspects of conflict is needed in public administration literature and practice. 相似文献
