Probabilistic Health Risk Assessment for Exposures to Estuary Sediments and Biota Contaminated with Polychlorinated Biphenyls, Polychlorinated Terphenyls and Other Toxic Substances

A Latin Hypercube probabilistic risk assessment methodology was employed in the assessment of health risks associated with exposures to contaminated sediment and biota in an estuary in the Tidewater region of Virginia. The primary contaminants were polychlorinated biphenyls (PCBs), polychlorinated terphenyls (PCTs), polynuclear aromatic hydrocarbons (PAHs), and metals released into the estuary from a storm sewer system. The exposure pathways associated with the highest contaminant intake and risks were dermal contact with contaminated sediment and ingestion of contaminated aquatic and terrestrial biota from the contaminated area. As expected, all of the output probability distributions of risk were highly skewed, and the ratios of the expected value (mean) to median risk estimates ranged from 1.4 to 14.8 for the various exposed populations. The 99th percentile risk estimates were as much as two orders of magnitude above the mean risk estimates. For the sediment exposure pathways, the stability of the median risk estimates was found to be much greater than the stability of the expected value risk estimates. The interrun variability in the median risk estimate was found to be +/-1.9% at 3000 iterations. The interrun stability of the mean risk estimates was found to be approximately equal to that of the 95th percentile estimates at any number of iterations. The variation in neither contaminant concentrations nor any other single input variable contributed disproportionately to the overall simulation variance. The inclusion or exclusion of spatial correlations among contaminant concentrations in the simulation model did not significantly effect either the magnitude or the variance of the simulation risk estimates for sediment exposures.     

A meta-analysis of research on adolescent contraceptive use

Meta-analysis was used to summarize the results of 134 studies of adolescent contraceptive use in relation to two major explanatory models, the career model and the decision model. There was evidence in support of both models, although there has been less research conducted on variables related to the decision model. The major variables found to affect young women's contraceptive use were partner influence to use contraception, acceptance of one's sexuality, future orientation, positive attitudes toward contraception, an exclusive sexual relationship, and frequency of intercourse. The major variables affecting young men's contraceptive use were partner influence, frequency of intercourse, and positive attitudes toward contraception; however, there was relatively little research on young men compared to young women. A number of possible future directions for research are noted.We would like to thank Nancy Adler and Catherine Chilman for their comments on an earlier version of this article.

The Subjective Well-being Construct: A Test of its Convergent,Discriminant, and Factorial Validity

Using structural equation modeling, we found empirical support for the prevailing theory that subjective well-being consists of three domains: (1) cognitive evaluations of one’s life (i.e., life satisfaction or happiness); (2) positive affect; and (3) negative affect. Multiple indicators of satisfaction/happiness were shown to have strong convergent validity as well as discriminant validity from positive and negative affect. Positive and negative affect likewise exhibited discriminant validity from one another. At both the item and scale levels of analysis, we obtained an intercorrelated three-factor solution corresponding to the three proposed subjective well-being domains.     

Spillover Between Work Attitudes and Overall Life Attitudes: Myth or Reality?

It is widely believed that work attitudes influence attitudes toward life overall. We investigated a multivariate model of work attitudes and overall life attitudes using survey data from two nationally representative (U.S.) data sets, one cross-sectional and one longitudinal. Including a comprehensive set of control variables, we found only weak support for the attitudes spillover perspective, suggesting that employees often compartmentalize or segregate their work and nonwork lives. We consider theoretical and practical implications of these findings.     

Child protection revisited: balancing state intervention and family autonomy through social work processes

This paper explores selected findings from a qualitative study of the 1989 Children Act, which examined ways in which the new definitions of significant harm were being interpreted in practice. Significant harm is seen as a major site where state intervention and family autonomy are balanced, especially through establishing thresholds for intervention. The data are analysed in relation to the social work processes of assessment, intervention and evaluation. These are seen as a series of interactions between families and practitioners, in which goals are identified, methods used and resources mobilized. Key decisions and levels of change address the paramountry of the child's welfare. These processes are also under-pinned by new legislative requirements. The practitioners displayed their professionalism during a period of transition and change. Social work processes facilitated non-judgemental practices which empowered the families in the difficult circumstances of their lives. The paper concludes that balancing state intervention and family autonomy requires social work of a high order and a profound understanding of complex issues.     

Parenting a 6-Year Old Is Not What I Planned in Retirement: Trauma and Stress among Grandparents Due to the Opioid Crisis

ABSTRACT

There is little research about trauma, financial stress, and social service needs emanating from the experience of parenting grandchildren caused by the opioid crisis in the United States. We conducted a qualitative study with 15 grandparents who currently or in the past had custodial care of their grandchildren. We also interviewed nine issue-related stakeholders in Eastern Massachusetts. Specific inquiries centered on events leading up to a change in guardianship, stressors related to legal, financial, and family issues, and system-wide response to the grandparents’ needs. Results indicate that the opioid crisis presents distinct challenges for the grandparent-led families and for the systems that serve the new family arrangement. Crisis triggers a change in guardianship and continues throughout the years. The continued crises stem from events related to the parent’s opioid use disorder (OUD) and from expenses related to raising a young family, especially when the grandchild has adverse childhood experiences. Our analysis shows that systems break down on a number of levels, and the fluidity of custodial arrangements due to parents’ OUD status does not map onto existing support or benefit systems. Policy responses must focus on the immediate and long-term needs of grandparent caretakers, especially since the opioid crisis is likely to continue.     

Separate but Equal: Durkheim's Response to the Woman Question*

This article reexamines Durkheim's views on gender relations within the context of nineteenth century French feminism. Durkheim's response to the woman question reflects the sociopolitical discourse on individual rights and responsibilities, the family, and women's roles in the private and public spheres. Durkheim's perspective on gender relations is predicated on a biologically differentiated conception of gender role complementarity that emphasizes the couple, not the individual. This perspective, shared by feminists, is best characterized by the phrase, separate, but equal.
