Medical nonadherence in pediatric HIV: Psychosocial risks and intersection with the child protection system for medical neglect

Nonadherence to antiretroviral treatment has serious health implications for HIV-infected children, at times warranting referral to child protective services (CPS). The current study of 134 children with perinatally acquired HIV infection aimed to investigate rates of treatment adherence and CPS involvement, multilevel variables associated with nonadherence, and the manner in which these risks operated together in the prediction of adherence outcomes. Risk factors for nonadherence were grouped on the basis of confirmatory factor models, and factor score regression was carried out to determine which factors were uniquely predictive of adherence. A series of indirect effects models were then tested in order to examine how these factors operated together in the prediction of adherence. Results showed that almost half of the sample demonstrated suboptimal adherence to treatment, and in one-fifth, CPS was involved for medical neglect. Caregiver Health, Caregiver Involvement, Caregiver Acceptance, and Child Adaptation were predictive of nonadherence, and together explained 54% of the variance in treatment adherence. There were significant indirect effects of Caregiver Health on adherence that operated through Caregiver Involvement and Child Adaptation and an indirect effect of Caregiver Involvement on adherence through Child Adaptation. Findings extend current literature that has independently linked various factors predictive of medical adherence in pediatric HIV by showing separate but simultaneous associations with nonadherence and unique pathways to adherence involving multilevel risks. Healthcare and child welfare implications are discussed.

The Implications of Teacher Selection and the Teacher Effect in Individually Randomized Group Treatment Trials

Abstract

In some experimental evaluations of classroom-level interventions it is not practically feasible to randomly assign teachers to experimental conditions. Given such restrictions, researchers may randomly assign students to experimental conditions and consider the teacher to be a part of the intervention. However, in an individually randomized evaluation of a classroom-level intervention, unless teachers are randomized to experimental conditions, it will not be clear whether differences in outcomes between program and control group students are a result of the core components of the intervention or the teachers (i.e., teacher effects). This article clarifies the correct interpretation of “program impacts” when this study design is used. In addition, using the magnitude of estimated teacher effects from past research, this article demonstrates that, if teachers are not randomly assigned to experimental conditions, it is difficult to establish whether the program works or whether the types of teachers selected to teach in program classrooms are simply more or less effective than their control group counterparts. The significant implications of the correct causal interpretation are discussed, and the limitations of this research design are explored.

Changing research trends in the field of archaeological wood at the Conservation Department,Faculty of Archaeology,Cairo University

Abstract

Since 1980, much research in the field of treatment and conservation of archaeological wood has been carried out at the Conservation Department, Faculty of Archaeology, Cairo University. Materials and methods used in conservation have been changing gradually over the years worldwide. It was necessary to study critically previous masters and doctoral dissertations on Egyptian archaeological and historic wood, all written in Arabic. This review of them includes a brief history of the Conservation Department at Cairo University and five main focal points of past research: types of wood used throughout Egyptian history, assessment of wood decay, wood properties and composition, treatment and conservation of decorated wood, and the evaluation of chemicals and polymers used in the treatment of archaeological wood and composite objects containing wood.
