In this investigation, the utility of a static light scattering (SLS) technique to characterize aggregate morphology of two-dimensional engineered nanomaterials (2D ENMs) was systematically evaluated. The aggregation of graphene oxide (GO) and lithiated-molybdenum disulfide (Li-MoS) were measured and compared to that of a spherical reference colloid, carboxylate-modified latex (CML) nanoparticles. The critical coagulation concentration (CCC) for all dispersions was determined via analysis of aggregation kinetics using time-resolved dynamic light scattering.

Sixty-one of 100 clinic-referred children (M age = 4 years, 4 months) originally diagnosed with oppositional defiant disorder (ODD) completed the standard treatment and were then randomized to PCIT maintenance treatment (MT) or to an assessment-only follow-up condition (AO). Rating scale and observational measures from fathers, mothers, and children were collected before and after standard treatment and at one- and two-year follow-up assessments.

Participants will include 96 parent-child dyads living in rural counties in north central Florida. Families will be randomized to one of two conditions: (a) behavioral family based intervention or (b) a waitlist control.

This study examined the psychometric properties of the Revised Edition of the School Observation Coding System (REDSOCS). Participants were 68 children ages 3 to 6 who completed parent-child interaction therapy for Oppositional Defiant Disorder as part of a larger efficacy trial. Interobserver reliability on REDSOCS categories was moderate to high, with percent agreement ranging from 47% to 90% (M = 67%) and Cohen's kappa coefficients ranging from .

This article reviews the literature from 1996 to 2007 to update the 1998 Brestan and Eyberg report on evidence-based psychosocial treatments (EBTs) for child and adolescent disruptive behavior, including oppositional defiant disorder and conduct disorder. Studies were evaluated using criteria for EBTs developed by the task force on promotion and dissemination of psychological procedures (Chambless et al., 1998; Chambless et al.

Participants were 99 families of 3- to 6-year-old children with disruptive behavior disorders. Multiple logistic regression was used to identify those pretreatment child, family, and accessibility factors that were predictive of success or attrition.

This led us to predict that verbal memory abilities would be more impaired in children treated for third ventricle tumors compared to those treated for cerebellar tumors. Archival data was obtained from 24 pediatric patients with third ventricle region tumors and 18 pediatric patients with cerebellar tumors.
