This paper investigates the role of location in determining the presence of on- and off-farm pluriactivity. Gravity models are developed to define degrees of access to markets from farm locations, and farm household survey data from the Grampian Region of Scotland are used to test the ability of the models to explain the observed location of pluriactivity. Proximity to markets is shown to be an important factor for both tourist and non-tourist on-farm diversification, and is reflected in the location of farms with on-farm non-agricultural activities. However, there is no evidence of a relationship between access to labour market opportunities and the presence of off-farm employment at the sub-regional scale. Personal preferences concerning work location and household responsibilities may be more important in determining the presence of off-farm work than proximity to labour market opportunities. Possible refinements to the technique and policy implications are discussed.  相似文献

Abstract

This article examines how mental health service users/consumers, advocates, professionals and researchers interpret and theorise the impacts of mental health news. It focuses on the following themes: Creating fears about mental illness by focusing on criminal and violent acts; Reinforcing power imbalances by privileging biomedical issues and sources; and Sanitising mental health issues through the selective use of personal narratives. The study draws upon the concept of biocommunicability, which casts light on the performative power of health news in reinforcing ideas and expectations about the appropriate role for different actors to adopt in relation to health knowledge. Previous research on health news has identified biomedical authority, patient-consumer and public sphere as three predominant models of biocommunicability and this article examines how these are bound up with criticisms of mental health news. The findings are related to the ‘mediatisation of psychiatric culture’ as one of extremes and perspectives from Mad Studies.  相似文献

White working‐class citizens who vote for the Republican Party have been fodder for much political discussion and speculation recently, and a debate has arisen about the role that “moral values” played in the political decision making of this segment of voters. In this article, we defend a version of the moral values claim. We show that although the Republicans’ policies are unpopular, they are bundled with an overarching moral framework that is extremely resonant to this set of voters, and we use in‐depth interviews to uncover this framework. A key feature of this framework, on which in the 2004 presidential election George W. Bush scored high and John Kerry scored low, is the appropriate attitude to wealth, which serves as an indicator for a candidate’s general moral philosophy and as a heuristic about whether the candidate will govern with working‐class voters’ interests in mind. National Election Studies data support the argument that this was a key influence on the voting decision in 2004, even controlling for voters’ partisan identification.  相似文献

One of the most curious aspects of the 2004 presidential election was the strength and resilience of the belief among many Americans that Saddam Hussein was linked to the terrorist attacks of September 11. Scholars have suggested that this belief was the result of a campaign of false information and innuendo from the Bush administration. We call this the information environment explanation. Using a technique of "challenge interviews" on a sample of voters who reported believing in a link between Saddam and 9/11, we propose instead a social psychological explanation for the belief in this link. We identify a number of social psychological mechanisms voters use to maintain false beliefs in the face of disconfirming information, and we show that for a subset of voters the main reason to believe in the link was that it made sense of the administration's decision to go to war against Iraq. We call this inferred justification : for these voters, the fact of the war led to a search for a justification for it, which led them to infer the existence of ties between Iraq and 9/11.  相似文献

Traditional stage models of LGBTQ identity development have conceptualized coming out as a linear process from “closeted” to “out” that all queer/trans individuals must follow if they are to be considered healthy and well adjusted. These stage models have been critiqued for their rigidity and absence of a dynamic understanding of the coming out process. In this article we explore the findings from a qualitative photovoice study with 15 LGBTQ youths in a small urban center in Ontario that supports these critiques. We explore the efficacy of the photovoice technique in investigating questions of sexual and gender identity. This article identifies some contextual factors that are important in understanding coming out as a social (rather than internal) process; it also identifies some of the ways in which these youths’ experiences challenge normative understandings of the “good, out queer.”  相似文献

Urban expansion is creating environmental stressors through land use change, habitat fragmentation, and habitat loss. These stressors, along with a host of others, are driving precipitous declines in vertebrate taxa around the world. Amphibians, often requiring a narrow range of environmental conditions, can be especially susceptible to the stressors of environmental change. Despite habitat loss and degradation, some amphibian species continue to persist in altered urban landscapes. The red-backed salamander (Plethodon cinereus) is one such- species and in this study, we assess how habitat patch size affects population density and genetic diversity of salamander populations in and around an urban center in Ohio, United States. Further, we examined patterns of genetic differentiation and landscape connectivity to understand gene flow between populations and tested for historic demographic bottleneck effects. Populations were sampled from 9 urban forest patches ranging in size from less than 1 ha to approximately 250 ha. There was no apparent effect of contiguous habitat patch size on salamander density nor genetic diversity, but we did observe significant genetic differentiation between 97% of pairwise population comparisons. The differentiation observed was not a result of overland distance or effective distance due to landscape resistance. There was evidence of historic bottlenecks at every site. These results suggest that density is driven by within-patch heterogeneity and that genetic diversity is affected by drivers other than patch size or contemporary population density. Our study demonstrates that red-backed salamanders can persist in wooded, urban parks, but that genetic diversity remains susceptible to demographic changes.

People experiencing homelessness have an increased risk of cold-related injuries. This study determined the rate of emergency department (ED) visits for cold-related injuries among homeless adults and low-income controls in Toronto, Canada. Homeless individuals were recruited at shelters and meal programs. Age- and sex-matched controls living in low-income neighborhoods were selected. ED utilization was ascertained over 4-years of follow-up (2005–9) using administrative databases. A total of 16 ED visits for cold-related injuries were observed among 587 homeless men and 296 homeless women. The rate of ED visits was 6.7 (95% CI, 4.2–12.4) per 1000 person-years of observation among homeless men and 0.9 (95% CI, 0.03–5.6) among homeless women. ED visit rates were significantly higher among homeless men compared to low-income men (P?<?0.001) and significantly higher among homeless men compared to homeless women (P?=?0.03). Targeted public health interventions are needed to reduce the risk of cold-related injuries among people experiencing homelessness.  相似文献

The present study takes a transactional approach to extend understanding of temporal relations between parenting behaviors and infant response to the face‐to‐face still‐face, a widely used method assessing infants’ affective and behavioral response to a violation of social expectations. A low‐income, urban sample of 180 mothers and infants participated when infants were 4 and 6 months old. Directional relations between infants’ still‐face response (i.e., change in affect and gaze from interaction to still face) and three parenting dimensions were examined using cross‐lagged structural equation models. Infant still‐face response predicted later parenting behavior, while the reverse association was not significant. Specifically, infants with a greater reduction in positive affect from interaction to still face had parents with more positive parenting and less negative parenting behaviors 2 months later, controlling for prior parenting and concurrent infant behavior. Furthermore, infants who increased gaze to mother from interaction to still face had mothers who used more mental state talk 2 months later. Findings underscore the importance of examining transactional relations between infant and parent behaviors, and in particular highlight the influence of infants on parents. Acknowledging these infant‐effects is critical to the development and implementation of interventions targeting parent‐infant interactions.  相似文献
