From Child Welfare to Jail: Mediating Effects of Juvenile Justice Placement and Other System Involvement

This study examines the effects of child welfare, mental health, and drug/alcohol system experiences on jail involvement, as mediated by juvenile justice placement, for Black and White youth/young adults. The sample was comprised of individuals born between 1985 and 1994 with child welfare involvement in an urban Pennsylvania county ( N = 37,079) and an out-of-home placement (OOHP) subsample ( n = 8,317). Four path models were estimated (two full samples, two subsamples; separate models for Black and White youth). For all models, juvenile justice placement was positively related to jail involvement. For the full samples, out-of-home child welfare placement was associated with an increase in juvenile justice placement. Within the Black placement sample, child welfare placement experiences had complex relationships with juvenile justice placement. Providing drug/alcohol services may be a protective factor for Black youth prior to juvenile justice contact. Articulating these relationships helps identify youth most at risk of justice system involvement and better targets services, especially mental health and drug/alcohol services.

An organocatalytic ring-opening polymerization approach to highly alternating copolymers of lactic acid and glycolic acid

Highly regioselective ring-opening polymerization of optically active methylglycolides was achived using P2-t-Bu/alcohol system to produce alternating copolymer of lactic acid and glycolic acid.

Molecular Interaction of Aqueous Solution of 1-Propanol and 2-Propanol

Viscosities (ƞ) of solutions of 1- propanol and 2-propanol have been determined in aqueous systems of varying composition (0.16-3.64 mol dm-3) at 298 K. The ƞ/ƞ0 data have been analyzed in the light of reduced Jone-Dole equation ƞ/ƞ0 = BC+1. The results in the regards to solute-solvent interaction in aqueous solutions of both the alcohols have been discussed in the terms of the value B. The result of study reveals that both the alcohols behave as the structure makers in the water. The result shows that solute-solvent type interaction of same magnitude exists in water-alcohol system.
