Importance of Uncertainty and Variability to Predicted Risks from Trophic Transfer of PCBs in Dredged Sediments

Biomagnification of organochlorine and other persistent organic contaminants by higher trophic level organisms represents one of the most significant sources of uncertainty and variability in evaluating potential risks associated with disposal of dredged materials. While it is important to distinguish between population variability (e.g., true population heterogeneity in fish weight, and lipid content) and uncertainty (e.g., measurement error), they can be operationally difficult to define separately in probabilistic estimates of human health and ecological risk. We propose a disaggregation of uncertain and variable parameters based on: (1) availability of supporting data; (2) the specific management and regulatory context (in this case, of the U.S. Army Corps of Engineers/U.S. Environmental Protection Agency tiered approach to dredged material management); and (3) professional judgment and experience in conducting probabilistic risk assessments. We describe and quantitatively evaluate several sources of uncertainty and variability in estimating risk to human health from trophic transfer of polychlorinated biphenyls (PCBs) using a case study of sediments obtained from the New York-New Jersey Harbor and being evaluated for disposal at an open water off-shore disposal site within the northeast region. The estimates of PCB concentrations in fish and dietary doses of PCBs to humans ingesting fish are expressed as distributions of values, of which the arithmetic mean or mode represents a particular fractile. The distribution of risk values is obtained using a food chain biomagnification model developed by Gobas by specifying distributions for input parameters disaggregated to represent either uncertainty or variability. Only those sources of uncertainty that could be quantified were included in the analysis. Results for several different two-dimensional Latin Hypercube analyses are provided to evaluate the influence of the uncertain versus variable disaggregation of model parameters. The analysis suggests that variability in human exposure parameters is greater than the uncertainty bounds on any particular fractile, given the described assumptions.     

“That Power and Privilege Thing”: Securing Whiteness in Community Work

In this article, I draw upon written texts and discussions with white community organizers so as to explore how the discourse of community work secure whiteness not as an act of maintaining privilege but as an accepted, unnoticed, and even helpful way of seeing and acting in the world. This is problematic because it creates a space in which there can be ethical white subjects who are able to understand themselves as outside of relations of racism. I suggest that it would be more useful to understand practices in which white people advocate with racialized communities as acts of ambivalence.     

Cultivating a Research Tool Kit for Social Work Doctoral Education

ABSTRACT

Social work doctoral education can prepare students to become research scholars whose work has impact by providing and promoting the development of an appropriately sophisticated and diverse research methods tool kit. Students can cultivate their tool kits through course work, mentored research experience, and specialized workshops. The tool kit is best grounded in guided reading of methodological texts—that is, reading methodological texts while conferring with advanced peers, faculty, and research supervisors—which provides essential teaching and experiences to enhance understanding and use. This article lays out a rationale for guided reading and provides an example of primer text and recommended readings to support guided reading for one set of related research methods: randomized experimentation and finite mixture modeling.     

A Review of: “Handbook of the Evolution of Human Sexuality. Edited by Michael Kauth.”

This study explores the role of the hostess club culture in the creation and maintenance of masculinity in Taiwan. The article focuses on flower drinking (the consumption of alcohol in bars, often integrated with prostitution), which is a common practice in Taiwan. Data were obtained from 58 in-depth interviews with men from a variety of occupations and social backgrounds (mean age = 38.50, SD = 11.00) and 73 questionnaires administered to soldiers (mean age = 21.00, SD = 1.10). Findings indicated that demonstration of skill at flower drinking and facility with the related social etiquette are important channels for male bonding that were central to the mid- to upper-class participants' professional development. Flower drinking also provided a method of discriminating men from other men through their choices of why and where to go and how to behave while there. Specific ways that Taiwanese masculinity differs from Western and from Japanese masculinity, and support for the continuing relevance of the traditional Confucian ideal of masculinity, wen-wu, are discussed.     

Responding to student mental health concerns in social work education: reflective questions for social work educators

In this paper, we explore ways in which social work educators might respond to students who report that mental health issues underlie their difficulty in meeting core competencies, or otherwise use the language of mental health to describe their struggles to succeed in social work programs. We discuss various trends in policy responses in Canada, the US, the UK, and Ireland. While there are general policy trends, it is clear that responding to these kinds of issues requires the development of highly flexible and situated policy processes that can respond to student realities, concern for students’ rights and privacy, and an awareness of potential discrimination against students. These processes also need to meet the specificities of practicums, particular institutional policies, the mandates of relevant professional bodies, and the precise local legislative framework that shapes these situations. Given these varying contexts, in this conceptual paper, we used a framework on disability that is informed by critical theory to engage existing school policies and propose a set of reflective questions that can guide schools of social work to create an overall responsive environment. These reflective questions are designed to help social work educators balance the rights and needs of students with the professional and institutional demands that students meet core competencies in their education.     

FROM THE SANCTUARY TO THE SLAMMER: EXPLORING THE NARRATIVES OF EVANGELICAL PRISON MINISTRY WORKERS

Current survey research reveals that religious conservatives exhibit more punitive attitudes toward criminal offenders than their nonreligious and mainline counterparts. Despite the pervasiveness of conservative Protestant support for the punitive treatment of criminal offenders, evangelical-run prison ministry programs have proliferated in recent decades. This study uses in-depth interviews to examine the motivations of prison ministry workers. The narratives demonstrate that prison ministry workers embrace a distinctive orientation of compassion and, through sustained contact with inmates, they negotiate the tension between conservative religious values and their practical experiences working in prison ministry. From this overarching theme of compassion, three important subthemes emerged: (1) the calling of prison ministry, (2) special connections to the prison context, and (3) a sense of comfort and security with inmates. Overall, we observe how prison ministers negotiate two competing moral logics—judgment and compassion—in light of their religious convictions and experiences with inmate outreach.     

Work–life Balance: Is it Now a Problem for Management?

In Western Australia (WA) there is substantial interest by public sector management in work–life balance (WLB) as a strategy to address labour supply problems. This article considers whether the positioning of WLB as a problem for management provides the opportunity for change resulting in an improved quality of working life in the public sector. We report on the implementation of WLB policies in four WA public sector agencies and conclude that managers are ‘managing’ WLB in a limited way, and largely in an individualized manner, at a level that does not disrupt the usual way of organizing work and employment. For many managers, employees' requests to access WLB policies are perceived as being in conflict with operational goals. The findings highlight the inadequacy of much of the WLB discourse that obscures the tension between, on the one hand, the imperative for managers to implement WLB more effectively and, on the other, organizational practices and the broader social, political and economic context in which management and the organization are located.     

The reverse environmental gender gap in China: evidence from "The China Survey"

Objectives This article explores gender differences in attitudes about the seriousness of the environment as a problem in China using the “2008 China Survey.” Methods We use generalized ordered logit models to analyze survey respondents’ environmental attitudes. Results Our results indicate that there is indeed a “gender gap” in environmental attitudes in China, but the pattern is reversed from what has been generally found in previous work conducted in the United States and Europe. Chinese men, not women, show a greater concern about environmental problems and the seriousness of the environmental degradation in China. Further, we find that this gender gap is based largely in the substantial economic and educational differences between men and women in contemporary China. Conclusions This study emphasizes the mediating influence of socioeconomic variables in explaining gender attitudes toward the environment in China. Our findings suggest that in different contexts, women may be faced with difficult decisions between immediate economic necessities and long-term environmental concerns. The observed environmental gender gap in China will likely persist unless further economic development results in improved access to education and economic conditions for Chinese women.     

The Implications of Demographic-Specific Inflation Rates for Trends in Real Educational Wage Differentials

We use data from consumer expenditure surveys to investigate the impact on trends in real wage differentials of using group-specific price indexes. We find that inflation rates decrease monoton-ically with the education of the household head throughout the 1970s and early 1980s, and real educational wage differentials, calculated using education-specific price indexes, widened somewhat more than nominal differentials. We also find that differences by education level in fuel and energy consumption, whose relative prices increased during the 1970s, account for the majority of the educational index differences.     

Evaluating the impact of conditional cash transfer programs on fertility: the case of the Red de Protección Social in Nicaragua

Evaluating the impact of poverty-reduction programs on fertility is complicated given that changes in incentives to have children take time to be incorporated into decision making and evaluation periods are usually quite brief. We explore the use of birth spacing as a short-run indicator of the impact of poverty-reduction programs on fertility. The data come from a Nicaraguan conditional cash transfer program that offers incentives for poor households to invest in children??s health, nutrition, and education. We estimate a stratified Cox proportional hazard model and find that the program decreased the hazard of a birth, indicating an increase in birth spacing.
