Improving students' performance via case-based e-learning by Sebastian Ertl, Sebastian Ertl, Patricia P. Wadowski, Henriette Löffler-Stastka

“…Consequently, we evaluated the efficacy of a case-based e-learning approach.MethodThe impact of a case-based interdisciplinary e-learning environment with an integrated question/feedback system on medical students' academic performance was examined in a cross-sectional sample of different study years, longitudinally matched per academic year. Differences between the groups were analyzed through an unpaired t-test.ResultsThe exam results of students who participated in the e-learning course (n = 296) were compared with those of all students at the university (n = 5,800). …”

Does Price Really Matter for Generic Alternatives? Supervised learning Approaches in Deciding the Right Price for Acceptable Quality Attributes of Amlodipine Besylate among Generic... by Laltanpuii Chenkual, Mahindran Mariyappan, Dimple S. Lalchandani, Khajapeer Shaikh, Pavan Kumar Sathala, Pawan Kumar Porwal

“…The linear dispersion of acceptable quality attributes was significantly different for AMLO besylate formulation with unit price per tablet “<1 Rs.” Although the correlations between price and quality are well-understood associations group centroid distance for price group “2–3 Rs.” and “1–2 Rs.” reveal that acceptable quality dispersion was similar for both groups. …”

VARIABILITY OF SPIKE PRODUCTIVITY IN F2 HYBRIDS OBTAINED BY CROSSING COMMON WHEAT VARIETIES NOVOSIBIRSKAYA 67, SARATOVSKAYA 29, AND PUZA-4 TO THE SKLE 123-09 MULTIFLORET LINE by V. S. Arbuzova, T. T. Efremova, P. Martinek, E. V. Chumanova, O. B. Dobrovolskaya

“…Skle 123-09 differed significantly from the studied cultivars in spike density, but no significant differences were found in spike length or the number of spikelets per spike. Two-way analysis of variance in F2 hybrids showed that the «spike length» variability character was determined mainly by the genotypic environment and the interaction of the factors «genotype × environment». …”
