Involvement with child protective services: Is this a useful question in population-based surveys?

Direct questions on child maltreatment in population-based surveys are often limited by ethical and methodological issues. This restricts the ability of researchers to examine an important aspect of early adversity and its relationship to health and behavior. An alternative to excluding issues of maltreatment entirely in population-based surveys is to include questions on child and family involvement with child protective services (CPS). A school-based adolescent survey that included a question on child and family involvement with CPS yielded results that were generally consistent with other studies relating child maltreatment to health and behavioral outcomes such as psychological distress symptoms, delinquency, aspects of bullying, and health service utilization. Such findings suggest that questions on involvement with CPS may be a reasonable proxy for child maltreatment. Despite the lack of information on the reason for involvement or specific categories of maltreatment, CPS involvement questions highlight the shared familial experience that surrounds CPS involvement and serves as a general reflection of an adverse experience that can be utilized by researchers interested in early experiences.     

Can Tracing Tools Contribute to Programming Proficiency? The LISP Evaluation Modeler

Abstract

Tracing solutions to programming problems is a long‐standing technique used to reveal the details of a solution and to expose bugs in a program. Tracing can also help programmers build a model or representation of how a programming language responds to code. This article describes the LISP Evaluation Modeler (LEM), an on‐line tracing tool designed to (a) help novices form an understanding of and facility with the LISP evaluation process, and (b) assist all programmers in designing and debugging programs. An empirical study of LEM demonstrates its advantages for design, comprehension, and debugging and suggests ways in which LEM can help novices learning LISP.
