Residential exposure to air toxics is linked to lower grade point averages among school children in El Paso,Texas, USA

Children in low-income neighborhoods tend to be disproportionately exposed to environmental toxicants. This is cause for concern because exposure to environmental toxicants negatively affects health, which can impair academic success. To date, it is unknown if associations between air toxics and academic performance found in previous school-level studies persist when studying individual children. In pairing the National Air Toxics Assessment risk estimates for respiratory and diesel particulate matter risk disaggregated by source, with individual-level data collected through a mail survey, this paper examines the effects of exposure to residential environmental toxics on academic performance for individual children for the first time and adjusts for school-level effects using generalized estimating equations. We find that higher levels of residential air toxics, especially those from non-road mobile sources, are statistically significantly associated with lower grade point averages among fourth- and fifth-grade school children in El Paso (Texas, USA).     

The participation of social services in youth justice systems in Europe

This article considers the participation of social services in youth justice systems in 11 European countries. In international children's rights instruments, the importance of the assessment of the background situation of juvenile defendants is acknowledged. In this article, three models for social work participation are proposed, on the basis of the distinction between adversarial and inquisitorial legal traditions and welfare and justice approaches towards youth justice. In the welfare model, social workers play the most active role in the youth justice process, whereas in the justice model, social workers have the least active role. In between, a mixed model can be found in which social workers play an active role in the youth justice system only to some extent.

Prevalence of Adult Problem and Pathological Gambling between 2000 and 2005: An Update

Background Excessive gambling is a prominent Public Health problem with high prevalence rates in many countries. Substance abuse and other co-morbidities often constitute a major health hazard for the person which gambles with a loss of material and social resources, as well as being a major concern for his or her significant others. The present study updates and extends prevalence data to include work published between 2000 and 2005 in English and other European languages. Methods In a three-step search and exclusion process, studies with current adult prevalence rates were gathered. Results Almost all studies fulfil basic research standards. The weighted mean prevalence rates for excessive gambling (problem and pathological) are 3.0% for the South Oaks Gambling Survey (problem 1.2%; pathological 1.8%), 3.3% for the Canadian Problem Gambling Index (problem 2.4%; pathological 0.8%) and 3.1% for the DSM-IV (problem 1.9%; pathological 1.2%). Conclusion The prevalence rates are comparable and relatively stable between countries and across survey instruments, and do not differ from earlier reviews. The regular epidemiological monitoring of excessive gambling remains a major Public Health issue although the distinction between pathological and problem gambling is not appropriate for epidemiological research. Further studies are needed with respect to concomitant lifestyle characteristics.     

Toward Disaster‐Resilient Cities: Characterizing Resilience of Infrastructure Systems with Expert Judgments

Resilient infrastructure systems are essential for cities to withstand and rapidly recover from natural and human‐induced disasters, yet electric power, transportation, and other infrastructures are highly vulnerable and interdependent. New approaches for characterizing the resilience of sets of infrastructure systems are urgently needed, at community and regional scales. This article develops a practical approach for analysts to characterize a community's infrastructure vulnerability and resilience in disasters. It addresses key challenges of incomplete incentives, partial information, and few opportunities for learning. The approach is demonstrated for Metro Vancouver, Canada, in the context of earthquake and flood risk. The methodological approach is practical and focuses on potential disruptions to infrastructure services. In spirit, it resembles probability elicitation with multiple experts; however, it elicits disruption and recovery over time, rather than uncertainties regarding system function at a given point in time. It develops information on regional infrastructure risk and engages infrastructure organizations in the process. Information sharing, iteration, and learning among the participants provide the basis for more informed estimates of infrastructure system robustness and recovery that incorporate the potential for interdependent failures after an extreme event. Results demonstrate the vital importance of cross‐sectoral communication to develop shared understanding of regional infrastructure disruption in disasters. For Vancouver, specific results indicate that in a hypothetical M7.3 earthquake, virtually all infrastructures would suffer severe disruption of service in the immediate aftermath, with many experiencing moderate disruption two weeks afterward. Electric power, land transportation, and telecommunications are identified as core infrastructure sectors.     

Disgusted subjects: the making of middle-class identities

Although the classed dimensions of ‘taste’ have, following Bourdieu, been widely discussed, expressions of disgust at perceived violations of taste have been less frequently considered in relation to class. This paper considers various expressions of disgust at white working‐class existence and explores what they might tell us about middle‐class identities and identifications. I argue that the narratives of decline and of lack present in such representations can be seen in terms of a long‐standing middle‐class project of distinguishing itself. Drawing on Bourdieu's critique of Kantian aesthetics, I argue that the ownership of ‘taste’ is understood as reflecting true humanity, and as conferring uniqueness. Ironically, however, this uniqueness is only achieved through an incorporation of collective, classed understandings. The paper calls for a problematization of a normative and normalized middle‐class location that is, I argue, given added legitimacy by a perceived decline in the significance of class itself. [A]n account of class, rank or social hierarchy must be thin indeed unless accompanied by an account of the passions and sentiments that sustain it (William Miller, The Anatomy of Disgust, p. 245). Social identity lies in difference, and difference is asserted against what is closest, which represents the greatest threat (Pierre Bourdieu, Distinction, p. 479). What we read as objective class divisions are produced and maintained by the middle class in the minutiae of everyday practice, as judgements of culture are put into effect (Beverley Skeggs, Class, Self, Culture, p. 118).     

Bicycle ergometry in subacute-stroke survivors: feasibility, safety, and exercise performance

This study evaluated the feasibility, safety, and findings from a protocol for exercise-bicycle ergometry in subacute-stroke survivors. Of 117 eligible candidates, 14 could not perform the test and 3 discontinued because of cardiac safety criteria. In the 100 completed tests, peak heart rate was 116 +/- 19.1 beats/min; peak VO(2) was 11.4 +/- 3.7 ml x kg x min(-1), peak METs were 3.3 +/- 0.91, exercise duration was 5.1 +/- 2.84 min, and Borg score was 14 +/- 2.6. Among 71 tests, anaerobic threshold was achieved in 3.0 +/- 1.7 min with a VO(2) of 8.6 +/- 1.7 ml x kg x min(-1). After screening, this protocol is feasible and safe in subacute-stroke survivors with mild to moderate deficits. These stroke survivors have severely limited functional exercise capacity. Research and clinical practice in stroke rehabilitation should incorporate more comprehensive evaluation and treatment of endurance limitations.     

Conversations for Connection: An Outcome Assessment of the Hold‐Me‐Tight Relationship‐Education Program,and Recommendations for Improving Future Research Methodology in Relationship Education

The Hold Me Tight (HMT) program is a new approach to relationship education based on Emotionally‐Focused Therapy (Johnson, 2004), an evidence‐based approach to couple therapy. In this exploratory longitudinal research, we examined individual growth in relationship satisfaction and trust for partners in 95 couples in 16 HMT groups across four occasions of measurement: Baseline, Pre‐Program, Post‐Program and at either 3‐ or 6‐month Follow‐Up. We found that relationship satisfaction and trust increased during program participation, and declined during follow‐up. We believe our findings provide support for the short‐term effectiveness of the HMT program, and suggest a longer period of program delivery may result in improved retention of gains. Finally, we present recommendations for improving the design of future longitudinal research in relationship education.     

Empirical Evaluations of Skinner’s Analysis of Problem Solving

We reviewed 12 studies in which the researcher taught problem-solving strategies, such as self-questioning and visual imagining, to children and adolescents with and without disabilities to facilitate the learning of math, spelling, play/social, and communication skills. We analyzed these studies in terms of types of problem-solving strategies, the multiple control involved in problem solving, the extent to which problem solving occurred at the overt or covert level. In addition to suggesting limitations of the literature, we recommend areas for future research and practice.
