An Approach to Assessing the Impacts of Incident-Free Transportation of Radioactive Materials: II. Highway Transportation

Annual radiation doses and risks to the public living near, and traveling on, public highways, and occupational doses are calculated for highway shipments of radioactive materials under accident-free and incident-free conditions (i.e., under normal transportation conditions). The database developed by Sandia National Laboratories is used, and calculations are made using RADTRAN 4.0. This report is one of two reports estimating radiological risk associated with transportation of radioactive materials.     

AN EXACT CONDITIONAL TEST FOR COVARIANCE SELECTION MODELS

An exact conditional test is developed for testing the absence of an edge in a graphical covariance selection model and is shown to be equivalent to a test based on the partial correlation coefficient. An example is given.     

DIFFICULT JOURNAL ARTICLE REJECTIONS AMONG PROLIFIC FAMILY THERAPISTS: A QUALITATIVE CRITICAL INCIDENT STUDY

This qualitative cirtical incident study examines the reactions and coping strategies of prolific family therapy scholars to difficult journal article rejections. Participants provide suggestions for ways to increase the likelihood of publication and to decrease the negative effects of journal article rejection. We discuss the implications of this investigations for the socialization of young professionals, the improvement of the journal review process, and the study of professional issues in family therapy.

Ambivalences: a challenge to permanency for children

A key to determining a permanent plan for children in placement lies in determining and working with the history and relative intensity of parental ambivalence in the parent-child relationship as it is acted out in the placement experience. A study of cases in a public department disclosed not only indicators of parental ambivalence but also the reinforcement of that ambivalence by agency policy, working conditions, and lack of resources.     

An iterative Monte Carlo method for nonconjugate Bayesian analysis

The Gibbs sampler has been proposed as a general method for Bayesian calculation in Gelfand and Smith (1990). However, the predominance of experience to date resides in applications assuming conjugacy where implementation is reasonably straightforward. This paper describes a tailored approximate rejection method approach for implementation of the Gibbs sampler when nonconjugate structure is present. Several challenging applications are presented for illustration.     

Low-Income Children's Participation in a Public Health Insurance Program in Georgia

To expand health care coverage to uninsured, low-income children, the Congress created the State Children's Health Insurance Program (SCHIP) in 1997. Given ample evidence that state Medicaid programs have failed to enroll many eligible children, experts questioned whether SCHIP could successfully enroll low-income children. Using Georgia state SCHIP data, we analyzed enrollment patterns and identified factors contributing to program enrollment. This study found that the children's enrollment is explained by perceived costs and benefits of joining the program as well as the underlying family structure, demographic factors, and health status. We discuss implications of these findings on the participation of low-income families in public sector programs.
