Purpose: This study aimed to assess the performance of the Ebel standard-setting method for the spring 2019 Royal College of Physicians and Surgeons of Canada internal medicine certification examination consisting of multiple-choice questions. Specifically, the following parameters were evaluated: inter-rater agreement, the correlations between Ebel scores and item facility indices, the impact ofraters’ knowledge of correct answers on the Ebel score, and the effects of raters’ specialty on inter-rater agreement and Ebel scores. Methods: Data were drawn from a Royal College of Physicians and Surgeons of Canada certification exam. The Ebel method was applied to 203 multiple-choice questions by 49 raters. Facility indices came from 194 candidates. We computed the Fleiss kappa and thePearson correlations between Ebel scores and item facility indices. We investigated differences in the Ebel score according to whethercorrect answers were provided or not and differences between internists and other specialists using the t-test. Results: The Fleiss kappa was below 0.15 for both facility and relevance. The correlation between Ebel scores and facility indices waslow when correct answers were provided and negligible when they were not. The Ebel score was the same whether the correct answerswere provided or not. Inter-rater agreement and Ebel scores were not significantly different between internists and other specialists. Conclusion: Inter-rater agreement and correlations between item Ebel scores and facility indices were consistently low; furthermore,raters’ knowledge of the correct answers and raters’ specialty had no effect on Ebel scores in the present setting

The spectroscopic investigation of new fluoreno-thiophene azomethines revealed that these compounds are fluorescent. However, they exhibit reduced fluorescence compared to native fluorene owing to competitive deactivation of the singlet excited state by nonradiative means involving both internal conversion and intersystem crossing. The absorption and emission wavelengths can be tuned and the HOMO-LUMO energy gap modulated from 2.0 to 3.2 eV by incorporating various electronic groups, number of azomethine bonds, and the fluorene-thiophene sequence. Electrochemical investigation confirmed that both oxidation and reduction occur resulting in irreversible radical ion formation.
