This paper first develops a model to characterize the equilibrium distribution of polluting and nonpolluting firms and then turns to the larger question of whether the equilibrium distribution is socially optimal. We find that the equilibrium distribution of polluting firms differs from the social optimum when they generate a large amount of stationary pollution and have much higher or lower productivity than clean firms. In these cases, conventional pollution control approaches generally do not bring about an optimal distribution. Consideration of transport costs along with productivity and pollution changes some of the classic results of the new economic geography literature.  相似文献

This paper investigates changes in subsistence strategies at the upland cave site of Nugljanska (Croatia) at the end of the last ice age, during a time of rapid sea level rise and changing environment. We analysed the faunal assemblage from archaeological levels spanning the Pleistocene–Holocene transition (15,000–8000 years BP) and evaluated changes in relative abundance of species, measured species diversity, and compared the representation of terrestrial mammal and marine resources. We found a significant shift in the most abundant prey species exploited (from red deer, Cervus, to wild boar, Sus). There was some correlation between dietary diversification and periods of increased moisture availability and the spread of deciduous forest in the area. Our results suggest that there was a continuing reliance on terrestrial resources throughout time and that changes in dietary patterns were likely due to local environmental change and potentially, changing seasonal mobility strategies, at the Pleistocene–Holocene transition.  相似文献

Public opinion features prominently in policy research because it sets bounds on the definition of policy problems and acceptable policy solutions. We contend that public opinion is also important for setting bounds on the level of government at which policy hazards are regulated by shaping preferences for uniformity of regulation and, relatedly, preferences for centralization. We offer a theoretical argument for why risk creates pressures for uniform standards and examine the extent to which preferences for uniformity and centralization are the product of fairly stable individual-level predispositions (e.g. partisanship and ideology) versus more fluid attitudes like perceptions of risk, which vary in response to crises, new information, and issue framing. We test our argument using survey data in the policy domain of food safety and find that individuals who anticipate greater risk from food-borne illness prefer more uniform food safety regulation, which translates into preferences for federal-level policymaking. Our results imply that contextual circumstances and strategic communications that influence risk perceptions can create not only generalized public demand for more regulatory policy but specific demand for uniform, centralized regulation.  相似文献

In the medieval Crown of Aragon it was customary for the corts to begin with a proposicio or opening speech made by the king. These Aragonese royal speeches were not merely confined to a brief summary of the political situation or a series of points to be considered but were elaborately constructed political sermons, in which affairs of state were portrayed in terms of Christian morality and nationalist pride, with the aid of exempla drawn from the Bible and other religious and classical works. An example is the speech made by Pedro IV ‘the Ceremonious’ of Aragon against the rebellion of the Judge of Arborea in Sardinia. A copy of this speech survives written in the king's own hand which raises the interesting question of whether the kings of Aragon were themselves responsible for the ideas expressed in these speeches and for composing them or whether their efforts were confined to reading out propaganda which was primarily the creation of royal officials.  相似文献

This article analyzes the thematic and visual content of ten years of nightly television news coverage of women in the workforce and employment discrimination. The authors find that the total amount of coverage is small, the visual context often undercuts the usually anti-discriminatory text, and NBC provided the most coverage. The possible sources of these patterns are examined: the elite newspaper agents, male domination of network news, decision-making, cultural definitions of event news, and consensus values and news controversy.  相似文献

In this paper exurbanization is regarded as a process involving the movement of a household from an urban area to another location beyond the contiguously built-up urban region but within its extensive commuting field. The primary definitive feature is that one or more persons within the household retains regular employment ties with the urban area. Although various influences on the inter-and intra-urban migration of households have been considered extensively in the migration literature (Clark 1982), exurbanization has yet to be placed in the context of this literature and examined with similar rigour. The issue, to paraphrase Rossi and Shlay (1982), is not just why households move, but why they choose to move where they do - that is, why have some become exurbanite households?  相似文献

DESIGN SPACES: AGGLOMERATION AND CREATIVITY IN BRITISH DESIGN AGENCIES   总被引:1,自引:0,他引:1  
Although there is a growing body of research into the cultural and creative industries, little work has focused specifically upon on the geography of design and its role in regional economies. The relative neglect of the geography of the UK design industry is surprising given recent assertions about the sector's role in national economic competitiveness; its contribution to product innovation; and its importance as an urban regeneration resource. This paper explicitly considers the extent to which existing conceptualizations of agglomeration and creativity provide insights into the realm of design. Our discussion reflects upon recent surveys of the design sector and analyses current design organization membership data, both of which reveal an overwhelming concentration of design activities in London and the South East. Our analysis of the strategies, organization and practices of agencies in London reveals that a number of the key features associated with cultural industries in general are significantly less discernible within design.  相似文献

This essay investigates the origins and assesses the advantages and disadvantages of the new field known as Wissensgeschichte from the perspective of an American intellectual historian. It argues that while some historians of science may be ready to embrace a new identity as historians of knowledge, this terminology remains baggy and invites facile applications of Foucauldian theory. The essay concludes with the hope that the history of knowledge approach may instead open up new avenues for conversation and collaboration between historians of science and garden variety historians.  相似文献
