Economic development has always been a moving target. Not surprisingly, there is growing evidence that the shape of economic policy and practice is significantly changing in many American states on the eve of the 21st Century. This article reviews the evolution and transformation of state economic development as well as its multidimentional character. The evolution includes roughly three broad, overlapping phases: a period when states focused on attracting businesses, a period when they focused on developing existing businesses, and a period when states refined and sharpened the strategies they already had in place. This article also offers evidence that a new, fourth phase is emerging in economic development. It is called cluster-based economic analysis and strategy development. This new approach has states addressing new issues, using new analytical tools, and experiencing new kinds of results. 相似文献

The thesis here expounded can be divided in three parts: in the first place, it is supposed that the syllogism is not the rhetorical way, and less still the logical way, indeed used to reach the decision in the legal proceedings monopolized by the modern State. At the most, it can be seen as a form of presenting a decision that has already been reached by other means. It sure constitutes a highly functional procedure, effective and legitimating. It is generally not a conscious strategy on the part of the so called official legal agents (judges, prosecutors, state attorneys, lawyers, plaintiffs), which seem to believe that the decision before the concrete case is in fact produced by the previous general norm enunciated by the system. If there would be a chronological order, the general norm comes afterwards. In the second place, the judicial discursive structure seems to be rather enthymematic than syllogistic, because not all the effectively used norms are revealed, many of them staying not only out of question but also hidden. Finally, it is suggested that, in the atmosphere of faking dogmatic law in which acts the underdeveloped State, those implicit norms are not just presupposed as evident, but they are also uncertain, being rendered to manipulation. 相似文献

This article outlines a set of criteria for assessing the value of e-consumer protection schemes. It is intended that it be used as a tool, for policy-makers, industry associations, corporations and consumer organisations in all jurisdictions, seeking to assess the appropriateness of their consumer protection regulation. It can be used to devise new, or improve existing, policies, and it can also be used to compare the usefulness of e-consumer protection in different jurisdictions. It commences with a brief review of existing frameworks for the protection of e-consumers, which demonstrates the need for a model that uncompromisingly presents the needs of consumers. An overview of the model is provided, followed by a presentation of the model's key features. A further section identifies the several ways in which the model can be applied in order to improve the usefulness of e-consumer protection. An earlier version of the model was published in checklist form (Clarke R. ‘A Major Impediment to B2C Success is … the Concept 'B2C' Invited Keynote, Proc. ICEC'06, Fredericton NB, Canada, 14–16 August 2006, at http://www.rogerclarke.com/EC/ICEC06.html#TNT). The present article revises and expands that checklist, and presents the rationale underlying each item in it. 相似文献

This article identifies key features of the sociotechnical contexts of computer law and security at the times of this journal's establishment in 1985, and of its 200th Issue in 2018. The infrastructural elements of devices, communications, data and actuator technologies are considered first. Social actors as individuals, and in groups, communities, societies and polities, together with organisations and economies, are then interleaved with those technical elements. This provides a basis for appreciation of the very different challenges that confront us now in comparison with the early years of post-industrialism. 相似文献

Age at death estimation in adult skeletons is hampered, among others, by the unremarkable correlation of bone estimators with chronological age, implementation of inappropriate statistical techniques, observer error, and skeletal incompleteness or destruction. Therefore, it is beneficial to consider alternative methods to assess age at death in adult skeletons. The decrease in bone mineral density with age was explored to generate a method to assess age at death in human remains. A connectionist computational approach, artificial neural networks, was employed to model femur densitometry data gathered in 100 female individuals from the Coimbra Identified Skeletal Collection. Bone mineral density declines consistently with age and the method performs appropriately, with mean absolute differences between known and predicted age ranging from 9.19 to 13.49 years. The proposed method—DXAGE—was implemented online to streamline age estimation. This preliminary study highlights the value of densitometry to assess age at death in human remains. 相似文献
