Implementing Core Entrustable Professional Activities in Undergraduate Medical Education: A Psychometric Study.

Purpose: This study examines the feasibility and psychometric results of an assessment of entrustable professional activities (EPAs) as a core component of the clinical program of assessment in undergraduate medical education, assesses the learning curves for each EPA, explores the time to entrustment, and investigates the dependability of the EPA data based on generalizability theory (G theory) analysis.

Method: Third-year medical students from the University of Minnesota Medical School in 7 required clerkships from May 2022 through April 2023 were assessed. Students were required to obtain at least 4 EPA assessments per week on average from clinical faculty, residents supervising the students, or assessment and coaching experts.

Nurturing Untapped Integration Expertise of MS4 Assessment Writers.

Creating original, integrated multiple-choice questions (MCQs) is time-consuming and onerous for basic science and clinical faculty. We demonstrate that medical students are co-experts to overcome assessment challenges of the faculty. We recruited, trained, and motivated medical students to write 10,000 high-quality MCQs for use in the foundational courses of medical education.

Diversification and trait evolution in New Zealand woody lineages across changing biomes.

Diversification of woody plant lineages in New Zealand has unfolded in complex physiographic, climatic, and environmental contexts. Many tree and shrub lineages have existed in New Zealand since the late Cenozoic when Forest was the dominant biome, subsequently diversifying (or continuing to diversify) during the Pliocene/Pleistocene as Open (below treeline) and Alpine biomes emerged. We examine the links between biomes occupied, traits, and diversification.

Macroevolutionary consequences of mast seeding.

Masting characterizes large, intermittent and highly synchronous seeding events among individual plants and is found throughout the plant Tree of Life (ToL). Although masting can increase plant fitness, little is known about whether it results in evolutionary changes across entire clades, such as by promoting speciation or enhanced trait selection. Here, we tested if masting has macroevolutionary consequences by combining the largest existing dataset of population-level reproductive time series and time-calibrated phylogenetic tree of vascular plants.

Pioneering polyploids: the impact of whole-genome duplication on biome shifting in New Zealand (Rubiaceae) and (Plantaginaceae).

The role of whole-genome duplication (WGD) in facilitating shifts into novel biomes remains unknown. Focusing on two diverse woody plant groups in New Zealand, (Rubiaceae) and (Plantaginaceae), we investigate how biome occupancy varies with ploidy level, and test the hypothesis that WGD increases the rate of biome shifting. Ploidy levels and biome occupancy (forest, open and alpine) were determined for indigenous species in both clades.

The effect of single biome occupancy on the estimation of biome shifts and the detection of biome conservatism.

Biome conservatism is often regarded as common in diversifying lineages, based on the detection of low biome shift rates or high phylogenetic signal. However, many studies testing biome conservatism utilise a single-biome-per-species approach, which may influence the detection of biome conservatism. Meta-analyses show that biome shift rates are significantly lower (less than a tenth), when single biome occupancy approaches are adopted.
