Accuracy of responses from postal surveys about continuing medical education and information behavior: experiences from a survey among German diabetologists
BACKGROUND: Postal surveys are a popular instrument for studies about continuing medical education habits. But little is known about the accuracy of responses in such surveys. The objective of this study was to quantify the magnitude of inaccurate responses in a postal survey among physicians. METHODS: A sub-analysis of a questionnaire about continuing medical education habits and information management was performed. The five variables used for the quantitative analysis are based on a question about the knowledge of a fictitious technical term and on inconsistencies in contingency tables of answers to logically connected questions. RESULTS: Response rate was 52%. Non-response bias is possible but seems not very likely since an association between demographic variables and inconsistent responses could not be found. About 10% of responses were inaccurate according to the definition. CONCLUSION: It was shown that a sub-analysis of a questionnaire makes a quantification of inaccurate responses in postal surveys possible. This sub-analysis revealed that a notable portion of responses in a postal survey about continuing medical education habits and information management was inaccurate

Court Intervention, The Consent Decree, and The Century Freeway
The Glenn Anderson Freeway-Transitway (the Century Freeway or 1-105) an Los Angeles County, to cost over two billion dollars, traverses nine cities and the County of Los Angeles. At completion in 1993, the Century Freeway will be seventeen miles long, six lanes wide, contain areas for high occupancy vehicles and for rail transit; it will be landscaped and noise attenuated, and it will be surrounded by thousands of units of housing which are linked to its development

Court Intervention, the Consent Decree and the Century Freeway
In 1972, a lawsuit. Keith v, Volpe. stopped implementation of the Century Freeway project and resulted in an injunction. By that time approximately 18,000 people had been displaced from the Century Freeway corridor. By the terms of the lawsuit, the then Division of Highways was required to develop a formal environmental impact statement on the entire Century Freeway project and to carry our additional public hearings. In 1979 parties to the lawsuit entered into a consent decree, amended two years later, which laid out the terms under which-the project would go forward. This injunction and consent decree were employed during a period of considerable regulatory and social change which nationwide was affecting the completion of public works projects, highways in particular. The period of the Century Freeway's early years has been called the time of the freeway revolution. Whatever it is labelled, it provided a context for interpretation of and response to the Century Freeway lawsuit and consent decree. The context involved: - legal changes (environmental, transportation and housing law enactments, enhanced access to judicial review of administrative agency actions, codification of the gains of the civil rights movement); - social changes (increasing environmental awareness, the public interest law movement, demands for greater participation in the workplace by women and minorities); - economic and political changes (adoption of a federal Urban Initiatives Program, changing leadership at Caltrans, decreased gasoline tax revenues because of the Arab oil embargo and the use of fuel-efficient vehicles). This report presents the results of a two year study of the Century Freeway undertaken under a Research Technical Agreement between UCI and Caltrans
