Trends in Assessment: Implications and Opportunities for Department Chairs

Learn about trends in assessment from the executive editor of Assessment Update and chair of the national-level Assessment Institute. Attention will be paid to the role of the chair in creating a culture of assessment, supporting student success, and in using assessment results to inform department planning and improvement efforts

Central Indiana STEM Talent Expansion Program: Student and Faculty Interventions

Funded by 5-year, $2M grant from the National Science Foundation, the Central Indiana STEM Talent Expansion Program (CI-STEP) at Indiana University-Purdue University Indianapolis (IUPUI) is creating a pipeline of students and a campus culture change to increase the number of undergraduates obtaining Science, Technology, Engineering, and Mathematics (STEM) degrees. CI-STEP addresses initiatives needed for transforming the undergraduate STEM experience by propagating, expanding, and creating new evidence-based educational innovations in undergraduate STEM education at IUPUI

Language of Lullabies: The Russification and De-Russification of the Baltic States

This article argues that the laws for promotion of the national languages are a legitimate means for the Baltic states to establish their cultural independence from Russia and the former Soviet Union

Young inversion with multiple linked QTLs under selection in a hybrid zone.

Fixed chromosomal inversions can reduce gene flow and promote speciation in two ways: by suppressing recombination and by carrying locally favoured alleles at multiple loci. However, it is unknown whether favoured mutations slowly accumulate on older inversions or if young inversions spread because they capture pre-existing adaptive quantitative trait loci (QTLs). By genetic mapping, chromosome painting and genome sequencing, we have identified a major inversion controlling ecologically important traits in Boechera stricta. The inversion arose since the last glaciation and subsequently reached local high frequency in a hybrid speciation zone. Furthermore, the inversion shows signs of positive directional selection. To test whether the inversion could have captured existing, linked QTLs, we crossed standard, collinear haplotypes from the hybrid zone and found multiple linked phenology QTLs within the inversion region. These findings provide the first direct evidence that linked, locally adapted QTLs may be captured by young inversions during incipient speciation
