Background: Although the relations among prematriculation, matriculation, and residency assessments have been studied, measures pertaining to clinical skills have rarely been incorporated in any analyses. Purpose: The purpose of this article was to investigate the relations between scores obtained on the Educational Commission for Foreign Medical Graduates Clinical Skills Assessment (CSA) prototype and aptitude-ability measures designed to select medical students, to assess medical students while in medical school, and to evaluate physicians in postgraduate training programs. The sample included 122 4th-year medical students. Methods: Relations among scores were summarized with correlation coefficients. Analysis of variance was used to compare CSA scores by departmental grades. Results: Significant correlations (p <. 01) were found between scores from assessments commonly used in medical school (i.e., United States Medical Licensing Exam [USMLE] Steps 1 and 2) and CSA component scores. There were weak associations between CSA measures and both Medical College Admissions Test scores and residency program evaluations. Conclusions: The relations between CSA scores and various other medically oriented ability measures provide additional evidence that inferences based on CSA scores are appropriate and valid.

The benefits and capabilities of an automated medical signal analysis system that can lead to more effective patient care are identified, the capabilities of different types of systems are briefly mentioned, and automated systems that support nominative and managerial decisions are described. The need for the practicing physician to anticipate computer hardware limitations and potential errors in programming are briefly discussed.

The Georgetown University Pediatric Pulmonary Program developed an automated Emergency Room patient record. The on-line, commercially available time-shared system, was used by four hospitals. No new technology was required for the system. Rather, existing technical capability was captured for use in a medical setting. An expanded version of the record system is now being tested in private physicians offices, county medical clinics and the University Pediatric Center.

Manual measurement of the forced expiratory spirogram (FES) is time consuming, tedious, and subject to observer variation. Application of computer capabilities to the acquisition, analysis and interpretation of the FES has led to the development of a program that is precise and accurate. The instrumentation and programming are presented as Part I of a two-part article, the second section of which is devoted to an assessment of the methods of validation applied to the program.

Operational data from a multiphasic test center operated by a city health department was subjected to systems analysis to derive implications for improved sensor management. The actual data process used facilities in Richmond, Va., Portland, Ore., and Washington, D. C., and required several weeks to complete assembly. The process had 3808 subjects at an average flow rate of 1.49 subjects per minut...

This letter examines the generalized Einstein relation that holds for degenerate as well as nondegenerate semicoductors. To facilitate its use in device design, asymptotic and middle-range approximations are set down and are used to plot the diffusivity-mobility ratio against carrier concentration for silicon and germanium.
