The International Atomic Energy Agency (IAEA) implemented an innovative project for assisting neutron activation analysis laboratories in improving the validity of their results by feedback workshops for discussion of results from participation in interlaboratory comparisons rounds in 2010. The participants learned during these meetings to identify the most probable sources of errors in their analytical procedures and how to implement corrective actions to prevent reoccurrence. The outcome of successive rounds between 2010 and 2018 is discussed and experiences during the feedback workshops are given. The quantitative evaluation of the results shows an overall improvement in satisfactory performance. Moreover, there is a clear indication that improvements are consolidated in most laboratories but also stimulate laboratories to develop to a higher level of excellence. Regional differences in performance are also analysed.

Incorporating modified team-based learning into a flipped basic medical laboratory course: impact on student performance and perceptions.

Authors:
Jing Shen Hongyan Qi Yingying Chen Ruhuan Mei Cencen Sun Zhengyang Wang

Department of Pulmonary and Critical Care Medicine, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Hangzhou, 310016, China.

Background: Basic medical laboratory courses (BMLCs) play an essential role in medical education and offer several benefits to students. Although various student-centered and active learning strategies have been increasingly incorporated into medical education, their applications in BMLCs are limited. This paper aimed to explore the educational effects of a flipped classroom (FC) combined with team-based learning (TBL) strategy in BMLCs at Zhejiang University School of Medicine. Read More

Need for cognition is associated with the interaction of reward and task-load on effort: A verification and extension study.

Authors:
Min Zhang Catherine V Palmer Sheila R Pratt Malcolm R McNeil Greg J Siegle

Int J Psychophysiol 2022 Aug 2;180:60-67. Epub 2022 Aug 2.

Department of Psychiatry, University of Pittsburgh, PA, USA.

Here, we work to provide nuance around the assumption that people will work for rewards. We examine whether individuals' inherent tendency to mobilize cognitive effort (need for cognition, NFC) moderates this effect. We re-analyzed our existing data to verify an effect reported by Sandra and Otto (2018) regarding the association between NFC and reward-induced cognitive effort expenditure, using a more ecological cognitive task design and adding a psychophysiological measure of effort.
