Peer-Modeled Mindsets: An Approach to Customizing Life Sciences Studying Interventions.

Mindset interventions, which shift students' beliefs about classroom experiences, have shown promise for promoting diversity in science, technology, engineering, and mathematics (STEM). Psychologists have emphasized the importance of customizing these interventions to specific courses, but there is not yet a protocol for doing so. We developed a protocol for creating customized "peer-modeled" mindset interventions that elicit advice from former students in videotaped interviews.

Phylogenetic and evolutionary implications of complete chloroplast genome sequences of four early-diverging angiosperms: Buxus (Buxaceae), Chloranthus (Chloranthaceae), Dioscorea (Dioscoreaceae), and Illicium (Schisandraceae).

We have determined the complete chloroplast genome sequences of four early-diverging lineages of angiosperms, Buxus (Buxaceae), Chloranthus (Chloranthaceae), Dioscorea (Dioscoreaceae), and Illicium (Schisandraceae), to examine the organization and evolution of plastid genomes and to estimate phylogenetic relationships among angiosperms. For the most part, the organization of these plastid genomes is quite similar to the ancestral angiosperm plastid genome with a few notable exceptions. Dioscorea has lost one protein-coding gene, rps16; this gene loss has also happened independently in four other land plant lineages, liverworts, conifers, Populus, and legumes.
