Integrated Substance Abuse and Child Welfare Services for Women: A Progress Review

A review of empirical literature reveals improvements in service utilization and outcomes for women when substance abuse and child welfare services are integrated. The increased use of substances by women involved in the child welfare system has resulted in a call for integrated, coordinated, evidence-based practices. Since the late 1990s, specific system- and service-level strategies have been developed to coordinate and integrate the provision of substance abuse and child welfare services such that women are remaining in treatment longer and are more likely to reduce substance use and be reunited with their children. The strategies reviewed provide useful guidelines for developing components of effective, evidence-based programs for substance-involved women in the child welfare system.     

Asymmetric generalizations of symmetric univariate probability distributions obtained through quantile splicing

Abstract

Balakrishnan et al. proposed a two-piece skew logistic distribution by making use of the cumulative distribution function (CDF) of half distributions as the building block, to give rise to an asymmetric family of two-piece distributions, through the inclusion of a single shape parameter. This paper proposes the construction of asymmetric families of two-piece distributions by making use of quantile functions of symmetric distributions as building blocks. This proposition will enable the derivation of a general formula for the L-moments of two-piece distributions. Examples will be presented, where the logistic, normal, Student’s t(2) and hyperbolic secant distributions are considered.

Facilitating the Career Development of Minorities: Doing it Differently This Time

Although the early vocational educators were committed to social change, they inadvertently reinforced differences between social groups. Counselors today have a unique opportunity to effect social change. Demographic shifts suggest that minorities who are educationally and occupationally prepared will face fewer racial barriers in the future labor market. To prepare minority students to take advantage of anticipated demographic shifts, counselors will need to avoid the same inadvertent mistakes made by their predecessors. To accomplish this, counselors can recommit to career education and counseling, ensure equal access to their services, and alter the context of their interventions.     

Protection against outliers in empirical bayes estimation

The proven optimality properties of empirical Bayes estimators and their documented successful performance in practice have made them popular. Although many statisticians have used these estimators since the landmark paper of James and Stein (1961), relatively few have proposed techniques for protecting them from the effects of outlying observations or outlying parameters. One notable series of studies in protection against outlying parameters was conducted by Efron and Morris (1971, 1972, 1975). In the fully Bayesian case, a general discussion on robust procedures can be found in Berger (1984, 1985). Here we implement and evaluate a different approach for outlier protection in a random-effects model which is based on appropriate specification of the prior distribution. When unusual parameters are present, we estimate the prior as a step function, as suggested by Laird and Louis (1987). This procedure is evaluated empirically, using a number of simulated data sets to compare the effects of the step-function prior with those of the normal and Laplace priors on the prediction of small-area proportions.     

Improving Educational Opportunities for Students With Disabilities Who Are Homeless

Students who are homeless constitute a unique subset within today's school population; those who also have disabilities face even greater challenges. This article highlights the uniaue needs of students with disabilities who are homeless, legislative mandates for serving these students (the McKinney Act and the Individuals with Disabilities Education Act), and promising practices for overcoming educational and institutional obstacles to service delivery. Suggestions will focus on developing collaborative relationships at multiple levels, creating responsive systems through staff development and procedural revisions, and providing students with the social and instructional support they need to be successful.
