Beyond Student Evaluations of Teaching and Educator Portfolios: A Multisource, Longitudinal System for Evaluating Teaching.

Traditional student evaluations of teaching and educator portfolios do not adequately assess the breadth and depth of medical educators' efforts. Current processes use limited perspectives, focus on a small portion of educators' work, and emphasize subjective opinions, which introduce bias.

Organically complexed iron enhances bioavailability of antimony to maize (Zea mays) seedlings in organic soils.

Antimony (Sb) is a metalloid belonging to group 15 of the periodic table. Chemical similarities between arsenic (As) and Sb produce concerns about potential health effects of Sb and enrichment in the environment. Antimony is found in oxic environments predominately as an oxyanionic species, antimonite (Sb[OH](6-)).
