Ensuring units invariant slack selection in radial data envelopment analysis models,and incorporating slacks into an overall efficiency score

This paper introduces a new methodology ensuring units invariant slack selection in radial DEA models and incorporating the slacks into an overall efficiency score. The CCR and BCC models are units invariant in their radial component, but not in their slack component, thus changing the units of measurement of one or more variables can change the models' solution. The proposed Full Proportional Slack (FPS) methodology improves the slack selections of the CCR and BCC models by producing slack selections that (a) are units invariant, thus producing fully units invariant models, (b) maximize the relative improvements represented by the slacks, and not their values, and (c) measure the full slacks that need to be removed from their corresponding variables. The FPS methodology is a fully oriented methodology first maximizing the improvements in the variables on the side of the orientation of the model. The Proportional Slack Adjusted (PSA) methodology incorporates the FPS slacks into an overall efficiency score, making it easier to interpret and use the results. The FPS and PSA methodologies are illustrated using an input oriented VRS Loan Quality DEA model with data from the retail branch network of one of Canada's largest banks.     

Challenges in the assessment of decision-making capacity

The considerations for and challenges of developing an instrument for the assessment of oder adult descision-making capacity are discussed. A variety of conceptual and methodological issues are discussed, using experience with the development of the Hopemont Capacity Assessment Interview to illustrate the directions one might take in instrument development. Research questions are raised in the context of these conceptual and methodological issues.     

Older children in preadoptive homes: issues before termination of parental rights

In many jurisdictions, after the end of reunification services to birthparents, but before termination of parental rights, children are placed with parents who are licensed as foster parents but are committed to adopting the child. Using case examples, this article discusses the emotional and psychological difficulties often encountered by children and their prospective adoptive parents when birthparent visitation takes place and legal uncertainties exist. In addition, this article offers clinical and policy recommendations to help both the children and families in these situations as well as the professionals who work with them.     

A culture of threat: right-wing extremism and negative identity formation in German youth

The specific case of Eastern Germany is illustrative of a more general framework for how identity formation, family processes, and humiliation, alienation, and deprivation are linked to local conditions or situational contexts.     

Helping foster parents cope with separation, loss, and grief

Major changes in planning for children in foster care have resulted in significant changes in the roles of and expectations for foster parents, accompanied by even less attention to the issues of foster families' grief and loss. This article focuses on (1) the many ways foster parents encounter loss and grief on a continuous basis; (2) factors that affect the intensity of the loss and the healthy expression and resolution of grief; (3) problems that can result when the grief of foster parents is not adequately addressed; and (4) ways in which professionals can be helpful to these caregivers around loss and grief.     

Preparing and Partnering with Families to Support the Adoption of Children from Foster Care

ABSTRACT

This investigation evaluated the effectiveness of a pre-placement education and preparation curriculum (PREP) for prospective foster/adoptive parents in improving attitudes toward children with prenatal substance exposure and their substance-using birth parent and increasing willingness to adopt these children. Participants included 1,836 prospective parents seeking adoption through foster care who received three 3-hour sessions of PREP. Prospective parents completed questionnaires assessing their knowledge about important issues involved in adopting a child from foster care, attitudes, and willingness to adopt children with a variety of characteristics. Changes from pre- to post-intervention were examined. Results indicated significant increases in self-reported knowledge; significantly more positive attitudes toward substance-abusing parents and children with prenatal substance exposure; and significantly increased willingness to adopt children with a variety of potential difficulties, including children with serious behavior problems, attention deficit hyperactivity disorder, and a biological history of mental illness. In sum, findings suggest that prospective adoptive parents who attended the PREP sessions felt better prepared by the end of training with regard to issues related to adoption of high-risk foster children with special needs, particularly those with prenatal substance exposure.     

Poisson regression with a surrogate X: an analysis of vitamin A and Indonesian children's mortality

"A Poisson regression model with a surrogate X variable is proposed to help to assess the efficacy of vitamin A in reducing child mortality in Indonesia. In a recent community trial, the mortality rate in villages receiving vitamin A supplementation was 35% less than in control villages. However, at base-line, control villages were found to have slightly higher rates of xerophthalmia, an ocular disease caused by vitamin A deficiency. It was therefore desirable to adjust the mortality comparison for base-line vitamin A levels as indicated by xerophthalmia prevalence. This paper presents a parametric errors-in-X regression model developed for this purpose. Likelihood methods for fitting and inference are discussed. The model is illustrated on the Indonesian data set."     

Experiences, concerns, and service needs of families adopting children with prenatal substance exposure: summary and recommendations.

Parents who adopted children from out-of-home care with prenatal substance exposure were interviewed four months after the child's placement in the home, and again after the first year regarding their experience with adoption and their concerns about their child's development, attachment, and behavior; aspects of parenting and the adoption process; effects of prenatal substance exposure; and availability and helpfulness of resources. Adoptive parents found parenting children with prenatal substance exposure to be both more rewarding and more difficult than they had imagined.
