Youth incarceration : restorative justice and social work practice
This project examined the problem of juvenile crime and incarceration. I explored how two Criminal Justice theories—Attribution theory and Deterrence theory—support and explain the problem, and how two Social Work theories—Social Justice theory and Responsive Regulation theory—offer an alternative view and solution to the problem. I explained the principles and program models of Restorative Justice and strived to understand why there are so few Social Workers involved in Restorative Justice programs. Through this work, I addressed the following questions: with Restorative Justice carrying similar values as the Social Work profession, why are Social Workers not involved in Restorative Justice programs? How can Social Workers become more involved? And how can Restorative Justice more readily be used in the Social Work profession—especially in the area or youth crime and incarceration? The purpose of this project was to examine and explore how Restorative Justice contributes to Social Work practice and how the use of Restorative Justice practices can improve the capacity of Social Work as a field to attend to the problem of youth crime and incarceration. The findings of this project show how little research has been conducted on Social Workers\u27 involvement in Restorative Justice programs. Professional Social Work\u27s direct involvement with the Criminal Justice system has declined markedly in the past 40 years, however Social Workers continue to have contact with individuals, families, and communities who are affected by crime and the Criminal Justice system. Restorative Justice offers a holistic approach toward work in corrections in which justice for the victim, offender, and the community are all relevant
Sensibilité d'Anopheles gambiae aux insecticides en Côte d'Ivoire
Des études sur la sensibilité d'#Anophles gambiae aux insecticides ont été menées dans des zones de riziculture en Côte-d'Ivoire. Les populations larvaires d'#An. gambiae de ce pays sont résistantes au DDT mais sensibles aux insecticides organophosphorés. Les populations adultes issues des environs de Bouaké sont résistantes au DDT et à la perméthrine. Elles présentent une forte présomption de résistance au propoxur. L'effet #knock-down$ de la deltaméthrine et de la lambdacyhalothrine est retardé et considérablement diminué. La souche témoin de Bobo-Dioulasso, ainsi que des populations provenant de la zone de Katiola, éloignée de la ville, sont toujours sensibles aux trois pyréthrinoïdes. La résistance aux pyréthrinoïdes dans Bouaké a peut-être été sélectionnée par l'utilisation intensive des bombes insecticides à usage domestique. (Résumé d'auteur
School Nutrition Policy: An Evaluation of the Rhode Island Healthier Beverages Policy in Schools
Background. School policies limiting the availability of sweetened beverages are often considered to be effective interventions for improving children\u27s diet and weight-related health. This study was designed to examine the effectiveness of the Rhode Island Healthier Beverage Policy in reducing consumption of unhealthy beverages and in producing changes in children\u27s weight status. Method. Students in 2 public middle schools in Rhode Island completed self-reported measures of dietary intake and were measured for height and weight prior to and 1 year following the implementation of a state-mandated healthier beverage policy. An inventory of beverages available in vending machines after the beverage policy was implemented provided a measure of adherence with the statewide policy. Results. Both surveyed schools demonstrated compliance with the beverage policy (ie, greater than 70% of available beverages complied). Self-reported consumption of sweetened beverages did not change significantly following policy implementation. Neither average BMI percentile for age and gender nor frequency of children in each weight category changed significantly 1 year after the policy was implemented. Conclusions. Although the healthier beverage policy was effectively implemented, it did not result in changes in self-reported sweetened beverage consumption or weight status 1 year later. Additional school policy and individual-level changes appear to be necessary to effect change in weight and dietary outcomes for children. © 2012 The Author(s)
Effect of Experimental Change in Children’s Sleep Duration on Television Viewing and Physical Activity
Background
Paediatric observational studies demonstrate associations between sleep, television viewing and potential changes in daytime activity levels.
Objective(s)
To determine whether experimental changes in sleep lead to changes in children's sedentary and physical activities.
Methods
Using a within-subject counterbalanced design, 37 children 8–11 years old completed a 3-week study. Children slept their typical amount during a baseline week and were then randomized to increase or decrease mean time in bed by 1.5 h/night for 1 week; the alternate schedule was completed the final week. Children wore actigraphs on their non-dominant wrist and completed 3-d physical activity recalls each week.
Results
Children reported watching more television (p < 0.001) and demonstrated lower daytime actigraph-measured activity counts per epoch (p = 0.03) when sleep was decreased (compared with increased). However, total actigraph-measured activity counts accrued throughout the entire waking period were higher when sleep was decreased (and children were awake for longer) than when it was increased (p < 0.001).
Conclusion(s)
Short sleep during childhood may lead to increased television viewing and decreased mean activity levels. Although additional time awake may help to counteract negative effects of short sleep, increases in reported sedentary activities could contribute to weight gain over time
Effect of Prenatal Lifestyle Intervention on Maternal Postpartum Weight Retention and Child Body MassIndex z-score at 36 Months
Background/Objectives We previously reported results from a randomized trial showing that a behavioral intervention during pregnancy reduced excess gestational weight gain but did not impact maternal weight at 12 months. We now examine the longer-term effects of this prenatal intervention on maternal postpartum weight retention and toddler body-mass-index z scores (BMIz) over 36 months.
Subjects/Methods Pregnant women (N = 264; 13.7 weeks’ gestation; 41.6% Hispanic) with overweight or obesity were randomized into usual care or prenatal intervention. Anthropometric assessments in mothers and toddlers occurred at baseline, 35 weeks’ gestation and after delivery at 6, 12, 18, 24, and 36 months.
Results At 36 months, prenatal intervention vs. usual care had no significant effect on the proportion of participants who returned to their early pregnancy weight or below (33.3% vs. 39.5%; p = 0.12) and had no effect on the magnitude of weight retained (2.8 [0.8, 4.8] vs 3.0 kg [1.0, 4.9], respectively; mean difference = 0.14 [−3.0, 2.7]). There was also no statistically significant intervention vs. usual care effect on infant BMIz or skinfold changes over time; toddler BMIz increased by 1.4 [−1.7, 1.0] units in the intervention group and 1.6 [−1.2, 1.8] units in the usual care group from delivery to 36 months (difference = 0.16 [−0.32. 0.63]). The proportion of toddlers at risk for obesity at 36 months was similar in intervention and usual care groups (28/77 [36.4%] vs 30/80 [37.5%]; p = 0.77).
Conclusions Compared with usual care, lifestyle intervention during pregnancy resulted in similar maternal and toddler anthropometric outcomes at 36-months postpartum in a diverse US sample of women with overweight and obesity. To sustain improved maternal weight management initiated during pregnancy, continued intervention during the postpartum years may be needed
Efficacy of Environmental Health E-Training for Journalists
Communities report a low level of trust in environmental health media coverage. In order to support risk communication objectives, the goals of the research study were to identify whether or not there is a gap in environmental reporting training for journalists, to outline journalists’ methods for gathering environmental health news, to observe journalists’ attitudes toward environmental health training and communication, and to determine if electronic training (online/e-training) can effectively train journalists in environmental health topics. The results indicated that environmental journalists have very little to no formal environmental journalism training. In addition, a significant percentage of journalists do not have any formal journalism education. Respondents most preferred to receive continuing environmental journalism training online. Online instruction was also perceived as effective in increasing knowledge and providing necessary reporting tools, even among participants adverse to online instructional methods. Our findings highlight the changing media climate’s need for an increase in electronic journalism education opportunities to support environmental health journalism competencies among working professional journalists
Discovery of Stable and Selective Antibody Mimetics from Combinatorial Libraries of Polyvalent, Loop-Functionalized Peptoid Nanosheets.
The ability of antibodies to bind a wide variety of analytes with high specificity and high affinity makes them ideal candidates for therapeutic and diagnostic applications. However, the poor stability and high production cost of antibodies have prompted exploration of a variety of synthetic materials capable of specific molecular recognition. Unfortunately, it remains a fundamental challenge to create a chemically diverse population of protein-like, folded synthetic nanostructures with defined molecular conformations in water. Here we report the synthesis and screening of combinatorial libraries of sequence-defined peptoid polymers engineered to fold into ordered, supramolecular nanosheets displaying a high spatial density of diverse, conformationally constrained peptoid loops on their surface. These polyvalent, loop-functionalized nanosheets were screened using a homogeneous Förster resonance energy transfer (FRET) assay for binding to a variety of protein targets. Peptoid sequences were identified that bound to the heptameric protein, anthrax protective antigen, with high avidity and selectivity. These nanosheets were shown to be resistant to proteolytic degradation, and the binding was shown to be dependent on the loop display density. This work demonstrates that key aspects of antibody structure and function-the creation of multivalent, combinatorial chemical diversity within a well-defined folded structure-can be realized with completely synthetic materials. This approach enables the rapid discovery of biomimetic affinity reagents that combine the durability of synthetic materials with the specificity of biomolecular materials
Genetic networks controlling retinal injury.
PURPOSE: The present study defines genomic loci underlying coordinate changes in gene expression following retinal injury.
METHODS: A group of acute phase genes expressed in diverse nervous system tissues was defined by combining microarray results from injury studies from rat retina, brain, and spinal cord. Genomic loci regulating the brain expression of acute phase genes were identified using a panel of BXD recombinant inbred (RI) mouse strains. Candidate upstream regulators within a locus were defined using single nucleotide polymorphism databases and promoter motif databases.
RESULTS: The acute phase response of rat retina, brain, and spinal cord was dominated by transcription factors. Three genomic loci control transcript expression of acute phase genes in brains of BXD RI mouse strains. One locus was identified on chromosome 12 and was highly correlated with the expression of classic acute phase genes. Within the locus we identified the inhibitor of DNA binding 2 (Id2) as a candidate upstream regulator. Id2 was upregulated as an acute phase transcript in injury models of rat retina, brain, and spinal cord.
CONCLUSIONS: We defined a group of transcriptional changes associated with the retinal acute injury response. Using genetic linkage analysis of natural transcript variation, we identified regulatory loci and candidate regulators that control transcript levels of acute phase genes
