Physician Self-Referral and Physician-Owned Specialty Facilities

Outlines issues of self-referral -- physicians referring patients to a group or facility in which they have a financial interest -- and the prevalence of physician-owned facilities, as well as the effects on healthcare quality, cost, and access

Municipal Insolvency: The New Chapter IX of the Bankruptcy Act

In this report we give an introduction to a constructive way of treating systems of polynomial equations and inequalities. We present a method called cylindrical algebraic decomposition (CAD) discovered 1973 by Collins. The method constructs a decomposition of Rn such that a given set of polynomials have constant sign on each component. All concepts needed to understand the algorithm is presented, e.g., polynomial remainder sequences, subresultants, principal subresultant coefficients, Sturm chains and algebraic number representations

Some bounds for the knot Floer τ\tau-invariant of satellite knots

Pathways to inflated responsibility beliefs in adolescent obsessive-compulsive disorder: a preliminary investigation

Background: An inflated sense of responsibility is characteristic of obsessive-compulsive disorder (OCD). No previous studies have investigated its origins. Five potential pathways to inflated responsibility beliefs have been proposed; these are tested in this study. Method: A novel measure, the Origins Questionnaire for Adolescents (OQA), was developed to assess experiences on these five pathways. Reliability of the OQA was investigated. The experiences on the five pathways to inflated responsibility beliefs of sixteen adolescents with a history of OCD were compared to sixteen adolescents with no history of OCD. Parents also reported on adolescents’ experiences on the five pathways. Results: Inter-rater reliability was high. The internal consistency of the subscales were only partly satisfactory. The groups differed on one pathway; the clinical group reported a higher sense of responsibility for significant incidents with a negative outcome prior to onset of OCD. Conclusions: An inflated sense of responsibility, in combination with the occurrence of specific incidents, might act as a vulnerability factor for development of OCD. Future research should consider how to measure the subtle effects of experiences of responsibility over the course of development

Fortran IV trent-surface program for the IBM 360 model 40 computer

A Fortran IV trend surface program with polynomial contouring and residual plotting has been adapted to the University of Alaska IBM 360 Model 40 Computer. The program will compute equations of polynomials of the first through sixth degree, measures of the goodness of fit of the surfaces, tabulate original data, x y coordinates and corresponding residuals for each surface; contour each polynomial, and plot original values and residuals for each surface computed
