The Effect of Risk Beliefs on Property Values: A Case Study of a Hazardous Waste Site1

Health risk beliefs of homeowners near a landfill site were assessed in a survey and compared to expert judgments of the health risks of living near the site. A bimodal distribution of health risk beliefs suggested sharp disagreement between the experts and at least some of the residents. Correlates of high risk beliefs included perception of odor from the site, exposure to media coverage of the problem, having children living at home, age (younger respondents more concerned), and gender (females more concerned). An aggregated neighborhood health risk belief predicted reductions in home prices even after controlling for home physical characteristics, such as size and other disamenities such as proximity to a freeway. In the 4100 homes near the site, the estimated depression in property values was estimated to total about $40.2 million before the site was closed and to be about $19.7 million after closure. Implications of these results for community conflict and for benefit-cost analysis of hazard site remediation are discussed.     

The Ethics of Research With Men who Have Learning Disabilities and Abusive Sexual Behaviour: a minefield in a vacuum

In the wake of the recent awareness of the sexual abuse of people with learning disabilities is the recognition that a small number of men with learning disabilities are themselves sexually abusing. The need to understand the men's behaviour and provide effective responses is pressing yet the search for an ethical course of enquiry appears illusory. The two conflicting dilemmas which make this task so difficult are whether the men's learning disabilities preclude their giving informed consent to the research process, and/or whether men who are sexually abusing have lost some rights to exclude themselves from research which is intended to prevent further abuse. This paper explores in depth these dilemmas and describes the authors' attempts to resolve them as they attempted to devise a protocol for consent to involvement in a qualitative study of men with learning disabilities who sexually abuse. Issues raised in this particular context have relevance to many other issues in learning disability services where robust ethical debate is needed, but often glossed over.     

Additive and Multiplicative Models and Multistage Carcinogenesis Theory

In light of the Armitage-Doll multistage carcinogenesis theory, this paper examines the assumption that an additive relative risk relationship is indicative of two carcinogens that affect the same stage in the cancer process. We present formulas to compute excess cancer risks for a variety of patterns for limited exposure durations to two carcinogens that affect the first and penultimate stages; and using an index of synergy proposed by Thomas (1982), we find a number of these patterns to produce additive, or nearly additive, relative risk relationships. The consistent feature of these patterns is that the two exposure periods are of short duration and occur close together.     

Role constraints and first ladies

The First Ladyship is an institution that consists not only of the perceptions of its various occupants, and the accumulated precedents they have established, but also of the perceptions of the various audiences to which the First Ladies have played, and the elite and popular expectations that have accumulated over time in response to those precedents. Certain roles and their attendant behaviors are, thus, more likely than other roles and behaviors to attract elite and/or popular supports, whereas others are more likely to founder against one or more of the audience constraints that are part of the political ecology in which any First Lady operates.     

“I've been independent for so damn long!”: Independence, masculinity and aging in a help seeking context

This paper draws on semi-structured interviews conducted with 36 older men to examine how older men's understandings of independence relate to their help seeking behaviours and health service use. We argue that discourses of masculinity and successful aging are both represented in men's talk about independence. Recognising that these discourses are intertwined is important for understanding how older men seek help and use health services. We outline the practice and policy implications of viewing older men's help seeking behaviours in this way, and how it might be useful for promoting older men's health.     

Social workers in private practice: What are they really doing?

At one level, private practice may represent a fairly evolved manifestation of the expanded professional growth and sophistication of the individual social worker who embarks upon this highly individualized proprietary enterprise. However, on a larger scale, this widespread shift toward private practice may indicate a collective disenchantment with agency practice per se and represent a concerted attempt to redefine the fundamental aims and values of social work practice.     

Acculturation and Risk Behavior among Pregnant Mexican American Females: A Structural Equation Model

The purpose of this study was to test a theoretical model designed to predict risk behavior (i.e., cigarette and/or alcohol use) in a sample of Mexican American females who were pregnant and ranged in age from adolescence to early adulthood. The model consisted of six hypothesized predictors–acculturation status, intergenerational family conflict, acculturative stress, educational attainment, household income, and age of respondent, which were proposed as antecedents of risk behavior. Structural equation modeling was used to test both the direct and indirect effects for a set of proposed antecedents to the tendency for Mexican American females to engage in risk behaviors. Several of the hypothesized relationships were supported, with the strongest predictors of risk behavior being acculturation status, intergenerational family conflict, and acculturative stress. An important conclusion was that risk behavior by Mexican American females increased as they became more acculturated to the social circumstances of the U.S. Another notable result was that risk behavior increased among Mexican American females as they experienced higher levels of intergenerational conflict within their families.     

Carbon dioxide emissions and economic growth: A structural approach

This paper uses data for 44 countries from 1970-1990, to investigate the relationship between economic growth and carbon dioxide emissions. Empirical results are obtained from a structural model from the empirical growth literature modified to include environmental 'bads'. Results suggest that richer countries exhibit technical progress in a way that economizes on carbon dioxide emissions but that poorer countries do not. Furthermore, there is no indication that the growth process is leading poorer countries to move towards the adoption of the same pollution-ameliorating technology as characterizes richer countries.     

Information subsidies and agenda-building during the Israel–Lebanon crisis

This study examined the impact of information subsidies on media coverage during a crisis. Using the July 2006 Israel–Lebanon conflict as a backdrop, this research reviewed access that U.S. military public affairs officers provided the media and analyzed subsequent coverage for the presence of the military's message. Coverage was more neutral to positive than negative. Items containing organizational messages were more positive; those quoting practitioner-facilitated sources introduced organizational messages into coverage and generated more positive coverage. Access to information subsidies had a positive impact on coverage and aided in the successful transfer of attribute salience from practitioners to the media.
