Explicating Correlates of Juvenile Offender Detention Length: The Impact of Race, Mental Health Difficulties, Maltreatment, Offense Type, and Court Dispositions

Detention and confinement are widely acknowledged juvenile justice system problems which require further research to understand the explanations for these outcomes. Existing juvenile court, mental health, and child welfare histories were used to explicate factors which predict detention length in this random sample of 342 youth from one large, urban Midwestern county in the United States. Data from this sample revealed eight variables which predict detention length. Legitimate predictors of longer detention length such as committing a personal crime or violating a court order were nearly as likely in this sample to predict detention length as other extra-legal predictors such as race, court disposition for mental health problems, child welfare involvement, and child physical abuse victimization. Many of the factors that increase duration of detention are actually disadvantages that these youth endure; therefore preventative and intervention measures are in order

Predicting Juvenile Delinquency: The Nexus Of Childhood Maltreatment, Depression And Bipolar Disorder

Background It is important to identify and provide preventative interventions for youth who are most at risk for offending behaviour, but the connection between early childhood or adolescent experiences and later delinquency adjudication is complicated. Aim To test for associations between specified mental disorders or maltreatment and later delinquency adjudication. Method Participants were a random sample of youth before the juvenile courts in two Northeast Ohio counties in the USA (n = 555) over a 4-year time frame (2003 to 2006). Results Logistic regression analysis identified a lifetime diagnosis of depression and/or bipolar disorder to be predictive of later youth delinquency adjudication, but found that childhood maltreatment (or involvement with the child welfare system) made delinquency outcomes less likely. Implications Study implications are discussed as they relate to professionals working in the fields of child welfare, social work, mental health and juvenile justice. Awareness of risks associated with maltreatment may have led to effective interventions, while there may be less awareness of risks from depression in young people; however, studies tend not to take account of intervention variables

The mechanisms of plaster drying

International audienceWe show that the drying rate of plaster pastes is significantly lower than that expected for a pure liquid evaporating from a simple homogeneous porous medium. This effect is enhanced by the air flow velocity and the initial solid/water ratio. Further tests under various conditions and with the help of additional techniques (MRI, ESEM, Microtomography) for measuring the drying rate and local characteristics (water content, porosity) prove that this effect is due to the crystallization of gypsum ions below the sample free surface, which creates a dry region and decreases the drying rate by increasing the length of the path the vapor has to follow before reaching the free surface

Analyse physico-chimique de l’eau de l’unité d’hémodialyse du chr de Saint- Louis (Sénégal)

L’insuffisance rénale chronique est un des problèmes majeurs de la santé publique dans le monde. Au Sénégal, une étude récente réalisée dans la population générale adulte avait retrouvé une prévalence de l’ordre de 6,1%. «L’eau pour dilution de concentrées d’hémodialyse» est produite en continue et utilisée en grande quantité chez l’hémodialysé chronique, donc il apparaît primordial de veiller à sa bonne qualité. Au Sénégal, aucune étude n’a été faite à ce jour pour évaluer l’efficacité du système de traitement de l’eau pour dilution des concentrés de dialyse dans les différents centres de dialyse du pays. L’objectif de ce travail est de contrôler l’efficacité du système de traitement de l’eau pour dilution de concentrées d’hémodialyse afin de s’assurer de son innocuité. Les prélèvements ont été effectués au niveau de trois points clés du circuit de traitement de l’eau pour hémodialyse. A l’entrée et à la sortie de l’osmoseur, à la sortie de la boucle de distribution. Les analyses ont été effectuées à l’aide d’électrodes spécifiques. Les valeurs de potentiels ont permis de tracer les courbes d’étalonnage. La détermination par régression des pentes et des ordonnées à l’origine de la relation de Nernst donne E(mV ) = B - A Log Cm avec des coefficients de corrélation variant entre 0,988 et 0,999 prouvant que 98% au moins des variations de tensions mesurées (E) sont attribuables à la concentration. L’analyse physico-chimique des teneurs en chlorures, nitrates et fluorures révèle des teneurs plus élevées à l’entrée de l’osmoseur qu’à la sortie. Ces basses valeurs découlent du rôle de l’osmoseur qui filtre une grande partie des électrolytes. Par contre, à la sortie de la boucle de distribution les teneurs en électrolytes des différents échantillons étaient plus importantes que celles à la sortie de l’osmoseur. Cette forte concentration en électrolytes atteste d’une pollution par la boucle de distribution de l’eau déjà filtrée par l’osmoseur. L’intérêt de cette étude réside dans le fait qu’elle met en lumière l’importance du contrôle de la qualité de l’eau pour l’hémodialyse et la nécessité d’un bon planning de maintenance préventive efficace de l’ensemble de la boucle de traitement d’eau au sein de chaque centre.© 2016 International Formulae Group.

In Senegal, a recent study in the general adult population found a prevalence of about 6,1%. "Water for diluting concentrated hemodialysis" is produced and used continuously at high levels in hemodialysis chronic. It is therefore essential to ensure its quality. In Senegal, no study has been done to assess the effectiveness of water treatment system for dialysis concentrates dilution in different dialysis centers of the country. The objective of this work is to monitor the effectiveness of the water treatment system for hemodialysis concentrated dilution to ensure its safety. The samples were taken on key issues of hemodialysis water’s treatment circuit. Three levels of sampling were selected. At the entrance and at the outlet of the reverse osmosis unit at the outlet of the distribution loop. Analyses were performed using specific electrodes. Potential values allowed us to map the calibration curves. Determination by regression of slopes and intercepts of the Nernst relation gives with correlation coefficients ranging from 0.988 to 0.999 showing that at least 98% of the measured voltages fluctuations (E) are attributable to the concentration. Physicochemical analysis of the levels of chlorides, nitrates and fluorides reveals higher levels at the entrance of the reverse osmosis unit than at the outlet. These low values resulting of the role of reverse osmosis which filter much of the electrolytes. For against, at the outlet of the distribution loop the electrolyte content of the different samples were greater than those at the outlet of the reverse osmosis unit. This high electrolyte concentration attests to pollution of the water distribution loop already filtered by reverse osmosis. The interest of this study lies in the fact that it highlights the importance of monitoring the quality of water for hemodialysis and the need for good planning for effective preventive maintenance throughout the water treatment loop within each center.© 2016 International Formulae Group.

Low Immune Response to Hepatitis B Vaccine among Children in Dakar, Senegal

HBV vaccine was introduced into the Expanded Programme on Immunization (EPI) in Senegal and Cameroon in 2005. We conducted a cross-sectional study in both countries to assess the HBV immune protection among children. All consecutive children under 4 years old, hospitalized for any reason between May 2009 and May 2010, with an immunisation card and a complete HBV vaccination, were tested for anti-HBs and anti-HBc. A total of 242 anti-HBc-negative children (128 in Cameroon and 114 in Senegal) were considered in the analysis. The prevalence of children with anti-HBs ≥10 IU/L was higher in Cameroon with 92% (95% CI: 87%–97%) compared to Senegal with 58% (95% CI: 49%–67%), (p<0.001). The response to vaccination in Senegal was lower in 2006–2007 (43%) than in 2008–2009 (65%), (p = 0.028). Our results, although not based on a representative sample of Senegalese or Cameroonian child populations, reveal a significant problem in vaccine response in Senegal. This response problem extends well beyond hepatitis B: the same children who have not developed an immune response to the HBV vaccine are also at risk for diphtheria, tetanus, pertussis (DTwP) and Haemophilus influenzae type b (Hib). Field biological monitoring should be carried out regularly in resource-poor countries to check quality of the vaccine administered

Feasibility of Onchocerciasis Elimination with Ivermectin Treatment in Endemic Foci in Africa: First Evidence from Studies in Mali and Senegal

The control of onchocerciasis, or river blindness, is based on annual or six-monthly ivermectin treatment of populations at risk. This has been effective in controlling the disease as a public health problem, but it is not known whether it can also eliminate infection and transmission to the extent that treatment can be safely stopped. Many doubt that this is feasible in Africa. A study was undertaken in three hyperendemic onchocerciasis foci in Mali and Senegal where treatment has been given for 15 to 17 years. The results showed that only few infections remained in the human population and that transmission levels were everywhere below postulated thresholds for elimination. Treatment was subsequently stopped in test areas in each focus, and follow-up evaluations did not detect any recrudescence of infection or transmission. Hence, the study has provided the first evidence that onchocerciasis elimination is feasible with ivermectin treatment in some endemic foci in Africa. Although further studies are needed to determine to what extent these findings can be extrapolated to other areas in Africa, the principle of onchocerciasis elimination with ivermectin treatment has been established

Online Teaching and Learning of Transferable Skills Through Task Group Practice Online Teaching and Learning of Transferable Skills Through Task Group Practice

Students joined online task groups to complete one assignment in a social work diversity class that aims at developing critical-thinking and group work as transferable skills. The researcher used a phenomenological perspective to analyze phenomena that occurred during the group development process. Fifty-six undergraduate students provided data on their groups regarding task-completion, interactions, and decision-making processes, as well as other factors that influenced the outcome of the group process. The analysis revealed that students learned and put into practice critical thinking and group work skills used as they dealt with group phenomena such as group composition, setting up a contract and effective communication channels, and conflict management. The significance of this teaching case resides in its potential to enhance the effectiveness of online teaching through task groups. Social work instructors, field liaisons, and supervisors who use this teaching method may deliver effective and efficient signature pedagogy to a high number of supervisees. Limitations reside in the qualitative nature of the collected data, as well as in the small sample size, which precludes the generalizability of the findings. Future work with quantitative methodologies wil
