Roads have manifold social and environmental impacts, including regional development, social conflicts and habitat fragmentation. ‘Road ecology’ has emerged as an approach to evaluate the various ecological and hydrological impacts of roads. This article aims to complement road ecology by examining the socio‐spatial processes of road building itself. Focusing on the Brazilian Amazon, a heavily‐studied context due to forest fragmentation by roads, the authors consider non‐state social actors who build ‘unofficial roads’ for the purpose of gaining access to natural resources to support livelihoods and community development. They examine four case studies of roads with distinct histories in order to explain the socio‐spatial processes behind road building in terms of profit maximization, land tenure claims, co‐operative and conflictive political ecologies, and constraints as well as opportunities afforded by the biophysical environment. The study cases illustrate the need for a multi‐pronged theoretical approach to understanding road building, and call for more attention to the role of non‐state actors in road construction.  相似文献

ABSTRACT.  In this paper we employ dichotomous, multinomial and conditional logit models to analyze the employment-migration behavior of some 380,000 U.K. university graduates. By controlling for a range of variables related to human capital acquisition and local economic conditions, we are able to distinguish between different types of sequential migration behavior from domicile to higher education and on to employment. Our findings indicate that U.K. female graduates are generally more migratory than male graduates. We suggest that the explanation for this result lies in the fact that migration can be used as a partial compensation mechanism for gender bias in the labor market.  相似文献

This study examines the interrelationship between external political support, internal organizational factors, and red tape, using a sample of information managers from state health and human service agencies. The study defines a red tape model and tests the model by structural equation modeling method. The study finds that political support has a direct effect on red tape. The higher the political support, the lower the level of red tape. The study also confirms an indirect effect of political support on red tape, mediated by developmental culture. Indirect effect through goal clarity has the correct sign but is not statistically significant. Practical recommendations are made for the political environment to provide the opportunity for managerial reforms that are often advocated.  相似文献

Community‐based efforts to address environmental problems occupy an increasingly large space on the environmental policy landscape. Advocates argue that local environmental institutions (LEIs) can deliver both procedural and environmental quality benefits. Yet, despite over a decade of expansive support, the performance of LEIs remains largely unknown, particularly with regard to environmental outcomes. In this article, we consider new environmental outcome data we compiled from local efforts to implement the Massachusetts Wetlands Protection Act. We find that stronger forms of LEIs generate both quantitatively and qualitatively better environmental outcomes, which suggests that LEIs may live up to their advocates’ expectations.  相似文献

Regulatory compliance has emerged as a central feature in the legitimization of the planning system, yet it remains relatively marginalized from academic scrutiny. This paper investigates the relationship between regulatory compliance and projects subjected to Environmental Impact Assessments (EIAs). It reviews, through an empirical field study, the levels of conformity with EIA driven planning approvals and considers, with the assistance of inputs from experienced professionals and theoretical perspectives of regulatory compliance how these might be improved.  相似文献

James Ramsay Hunt (1874-1937) was a pre-eminent twentieth-century American neurologist. The name of Ramsay Hunt is known today because several neurological disorders bear his name, including the herpetic geniculate ganglion syndrome and a form of ataxia and myoclonus. Despite his importance in the field of neurology, few biographical details have been recorded about Hunt's life. One of the authors of this report recently located Hunt's daughter. This biographical sketch was based on interviews conducted with her and review of documents in her possession, including letters written by Hunt. Details are depicted about Hunt's family background and childhood, medical education and early professional development, courtship and marriage, wartime experiences, family and social life, daily routine and professional development, as well as illness and death.  相似文献

Harvesting different species as foods or raw materials calls for differing skills depending on the species being harvested and the circumstances under which they are being taken. In some situations and for some species, the tactics used are mainly behavioral—that is, people adjust, or adapt, their own actions to fit the behavior and circumstances of the species they are taking. Under other circumstances and for other species, the skills and tactics used may call for greater environmental preparation or manipulation. Therefore, instead of trying to distinguish people today and in the past as either foragers or farmers, it makes sense to define human subsistence behavior as an interactive matrix of species and harvesting tactics, that is, as a provisions spreadsheet.  相似文献
