The institution of more regulated and spatially distinctive work practices from the early-eighteenth century onwards, together with the later Victorian penchant for classification, “cost-benefit analysis” and social theorizing drew increasing attention to the nature and use of leisure time amongst the ordinary mass of people. Mid-nineteenth century theorems began to advocate causal connections between the perceived inactivity of most leisure forms and the moral decline of the working class, and adherents to such theorems sought thereafter to institute new and improving means of recreation, or more extremely, re-Creation as a cure for the Nation's ills. Drawing further strength from constructed contrasts between the precepts of an earlier aristocratic and leisured eighteenth century, the Victorian “recreationists” sought both temporal means (based upon the use of Sunday particularly) and spatial strategies (from the design of the home, through to the set-aside space of the seaside resort) to instil discipline into leisure and to marginalize certain forms of unacceptable behaviour.  相似文献

Cet article est consacré à l'étude de quelques uns des aspects de la philosophie de l'histoire de Walter Benjamin qui, aujourd'hui, suscitent le plus d'intérêt. En pratique, il analyse la notion de progrès, le rôle joué par l'écoulement du temps et l'interruption messianique. Il insiste aussi sur la critique du marxisme vulgaire entreprise par W. Benjamin et met en évidence ses apports les plus personnels ; enfin, il attire l'attention sur le risque encouru par les historiens qui orientent leur travail vers le futur et se montrent aveugles en ce qui concerne le passé.  相似文献

The two most famous peace projects published at the time of Louis XIV are William Penn’sEssay towards the present and future peace of Europe and Castel de Saint-Pierre’sProjet pour rendre la paix perpétuelle en Europe, which came out in English in 1693, and that of the abbé de Saint-Pierre, which was published in its completed form in several volumes dating from 1713 to 1716. A French translation of Penn’s book was issued in 1697 at the latest and was privately distributed. Our claim is that Saint-Pierre was in some way involved in that translation and that he was indebted to Penn for many of his ideas.  相似文献

The strategies of large firms have a major influence on the evolution of the global information society because they dominate the markets for information and communication technologies. This paper examines the user rather than the producer role of large firms, and focuses on the surrounding issues relating to evolving patterns of work and employment. Its discussion of these issues and their policy significance reflects the perspective of the EU on what is effectively a global agenda on the future of work in the information society.  相似文献

ABSTRACT. Real variable analysis has een used to great benefit in a variety of classical problems in location theory. In this paper we explore basic complex variable techniques in one formulation of the obnoxious location problem. A general definition of center points is first given and used to formulate several alternate versions of the obnoxious location problem. A logarithmic transformation is then used to demonstrate some equivalences between these families of distinct location problems (defined via center points). A prototype logarithmic potential function which results from this formulation is then investigated, and it is demonstrated that the extremal solutions with this objective reside on the boundary of its domain of definition. An application using zero- and one-dimensional centers is discussed, and a generalization to the spatial obnoxious problem is also briefly examined. We define a zero-dimensional center as a critical point of the logarithmic potential function, and it is shown that these centers are equivalent to the solutions of the Complex Moment Problem.  相似文献

The controversy over the fortunes of English towns in the later middle ages has tended to generate more heat than light. Much of the evidence employed in this debate has been drawn from the larger English towns, but this essay suggests a widening of the research agenda to include a more systematic assessment of small towns and village markets. Although weakened by the reduced demand for grain after the Black Death, these places competed for the growing local trade in basic consumer goods. Evidence from northeast Hertfordshire reveals that this competition resulted in a significant restructuring of the hierarchy of local marketing centres, and a decline in the ability of seigneurial and urban authorities to regulate trading activity.  相似文献

This paper suggests that there has been a small shift in American agricultural practices, and more importantly in policy making in this area, toward what can be called organic or alternative agriculture. These policy changes are partially due to triggering devices, exogenous forces that have led to changes in the policy agenda. Two major exogenous factors are reviewed–the energy “crisis” and environmental factors. Both sets of forces have resulted in farmers beginning to turn to alternative agricultural techniques, in government officials changing their attitudes about alternative agriculture, and new research activities in this direction being undertaken by various government bodies.  相似文献
