In 2006, land use planning emerged as a contested issue in the rural area known as ‘Down East’, Carteret County, in eastern North Carolina, USA. Down East is experiencing a transition from a commercial fishing to an amenity economy and concerns about related changes led to the formation of ‘Down East Tomorrow’ (DET), a grassroots group that proposed a one-year development moratorium in order to facilitate a community planning process. In this paper, we use political ecology to examine the fate of the moratorium as reflected in the public written record, primarily minutes of meetings of the Carteret County Board of Commissioners. We illustrate how issues of community, science, and governance were linked to an increasing focus on coastal water quality in the debate, and argue that this focus facilitated a switch by the Board from considering a development moratorium to adopting a conservation ordinance, one that fell short of addressing DET’s concerns. This outcome illustrates the power of formal political institutions in ’First World’ environmental conflicts and the difficulties of reconciling competing values associated with land use in areas of transition, especially where historical resistance to planning has been the norm.  相似文献

This study identified homelessness, substance use, employment, and mental health correlates of homeless youths' arrest activity in 5 cities. Two hundred thirty-eight street youth from Los Angeles, Austin, Denver, New Orleans, and St. Louis were recruited using comparable sampling strategies. Ordinary least squares (OLS) regression results reveal that being arrested for criminal activity is associated with length of homelessness, history of juvenile detention and incarceration, receiving income from theft, substance abuse, and mental illness. Arrests are also associated with interactions between lack of formal employment income and receiving income from theft and between drug and alcohol abuse/ dependency. Understanding the health and situational factors associated with homeless youths' delinquent activity has implications for providing more comprehensive health, mental health, and substance abuse services.  相似文献

Both a resource-based view and transaction cost economics perspective point to firms deciding to either make-or-buy an input. In practice, this tends to result in low-skill functions being outsourced while those of higher value are retained. In this article, we explore a situation counter to the prevailing literature. We study a highly creative industry – fashion – and discover the relationship between core competence and outsourcing is not as simple as previously conceptualised. Creativity, fashion's assumed competency, rather than being guarded within a firm is instead often outsourced or borrowed. More mundane tasks such as marketing and logistics are what each firm rather develops. The effects of resulting co-dependencies are mapped and analysed in order to offer managerial insight as well as contribute to discussion within the outsourcing and resource based literatures.  相似文献

Genetic differences (polymorphisms) among members of a population are thought to influence susceptibility to various environmental exposures. In practice, however, this information is rarely incorporated into quantitative risk assessment and risk management. We describe an analytic framework for predicting the risk reduction and value-of-information (VOI) resulting from specific risk management applications of genetic biomarkers, and we apply the framework to the example of occupational chronic beryllium disease (CBD), an immune-mediated pulmonary granulomatous disease. One described Human Leukocyte Antigen gene variant, HLA-DP beta 1*0201, contains a substitution of glutamate for lysine at position 69 that appears to have high sensitivity (approximately 94%) but low specificity (approximately 70%) with respect to CBD among individuals occupationally exposed to respirable beryllium. The expected postintervention CBD prevalence rates for using the genetic variant (1) as a required job placement screen, (2) as a medical screen for semiannual in place of annual lymphocyte proliferation testing, or (3) as a voluntary job placement screen are 0.08%, 0.8%, and 0.6%, respectively, in a hypothetical cohort with 1% baseline CBD prevalence. VOI analysis is used to examine the reduction in total social cost, calculated as the net value of disease reduction and financial expenditures, expected for proposed CBD intervention programs based on the genetic susceptibility test. For the example cohort, the expected net VOI per beryllium worker for genetically based testing and intervention is $13,000, $1,800, and $5,100, respectively, based on a health valuation of $1.45 million per CBD case avoided. VOI results for alternative CBD evaluations are also presented. Despite large parameter uncertainty, probabilistic analysis predicts generally positive utility for each of the three evaluated programs when avoidance of a CBD case is valued at $1 million or higher. Although the utility of a proposed risk management program may be evaluated solely in terms of risk reduction and financial costs, decisions about genetic testing and program implementation must also consider serious social, legal, and ethical factors.  相似文献

In this paper we share our collaborative experience of making a video in which disabled women present their lives as they wish to portray them. We undertook what we hope will be perceived as emancipatory research, in which disabled and non-disabled women work together to create audio-visual teaching materials. We include a preliminary discussion about the representation of disability on British television broadcasts between October 1991 and March 1992. We look at negative imagery, charity fund raising, and positive images. The paper uses comments by disabled broadcasters and disabled academics, and reflects on their work.  相似文献

Fertility desires and fertility: Hers,his, and theirs   总被引:3,自引:0,他引:3  
The relationship between desired and achieved fertility may be misspecified by excluding husbands' fertility desires or by confounding effects of shared desires with the resolution of conflicting desires. Using couple data from the classic Princeton Fertility Surveys, we find relatively large husband effects on fertility outcomes as well as unique effects of spousal disagreement. Wives and husbands were equally likely to achieve fertility desires, and disagreeing couples experienced fertility rates midway between couples who wanted the same smaller or larger number of children. These conditions do not hold, however, when we include willingness to delay births for economic mobility as part of the measure of fertility desires. Among couples who both wanted a third child, only husbands' willingness to delay births had significant negative effects on birth rates.  相似文献
