Resident selection: applicant selection criteria compared with performance.

One hundred three surgical house officers, 41 in general surgery and 62 in specialty surgery, entered the residency program from 1975 through 1979. Their application data, including the National Board of Medical Examiners test part I scores, preclinical course honors, clinical course honors, surgical clerkship honors, election to Alpha Omega Alpha (AOA), published research, medical school grading system, medical school rating, and National Resident Matching Program rank, were tabulated. Each house officer's performance was assessed by monthly faculty evaluation and by annual standard American Board of Surgery In-Training Examination (ABSITE) score through the second year of the program. The application data were compared with the performance data to determine significant indicators of success. Factor analysis computed on the monthly evaluation forms identified a knowledge factor and an interpersonal skills factor. Statistical analyses were used to study the relationships among the independent (preentry) variables and the knowledge, interpersonal skills, and ABSITE postentry variables. The results were significant (P less than 0.05) for medical school honors, election to AOA, and medical school grading system. No significance was found for the remaining preentry variables. The knowledge and interpersonal skill evaluation scores for the house officer I and II years were significantly correlated. Although the postentry assessment of knowledge correlated with certain applicant data, the assessment of interpersonal factors was not statistically related.

Macrostructure of selected raw starches and selected heated starch dispersions.

The similarities and differences between raw starches and heated starch-water dispersions were determined pictorially using a scanning electron microscope. The photomicrographs showed that raw unmodified starches ranged from small and round to large and ellipsoidal in shape, with variation in uniformity and smoothness of the surface. Heating of corn and wheat starch in water dispersions caused swelling of the starch granule, some exudate, and eventual loss of original granule integrity. The scanning electron microscope is a sensitive, useful tool to evaluate changes which occur in starch systems.

[Selection of a statistical model for evaluation of the reliability of the results of toxicological analyses. I. Discussion on selected statistical models for evaluation of the systems of control of the results of toxicological analyses].

2 statistical models for evaluation of toxicological studies results have been presented. Model I. after R. Hoschek and H. J. Schittke (2) involves: 1. Elimination of the values deviating from most results-by Grubbs' method (2). 2. Analysis of the differences between the results obtained by the participants of the action and tentatively assumed value. 3. Evaluation of significant differences between the reference value and average value for a given series of measurements. 4. Thorough evaluation of laboratories based on evaluation coefficient fx. Model II after Keppler et al. As a criterion for evaluating the results the authors assumed the median. Individual evaluation of laboratories was performed on the basis of: 1. Adjusted test "t" 2. Linear regression test.
