This article proposes that in addition to training teams of students to succeed in the Mathematical Contest in Modeling, the contest and the preparation for competition can be successfully used as a framework to teach an auxiliary skill set to undergraduate STEM majors through workshop-style modules. The skills emphasized are collaboration across…

In recent years, a principal supply shortage crisis has emerged in the USA. This problem has been exacerbated by an increase in principal departures, which has been found to be negatively related to school outcomes. While research exists on several determinants of principal turnover, any examination of the relationship between principals'…

Exploring how people represent natural categories is a key step toward developing a better understanding of how people learn, form memories, and make decisions. Much research on categorization has focused on artificial categories that are created in the laboratory, since studying natural categories defined on high-dimensional stimuli such as…

This dissertation uses quantitative and geographic analysis techniques to examine the historical and geographical processes that have shaped California's linguistic diversity. Many questions in California historical linguistics have received diminishing attention in recent years, remaining unanswered despite their continued relevance. The studies…

This study uses Monte Carlo simulations to demonstrate that regression-discontinuity designs arrive at biased estimates when attributes related to outcomes predict heaping in the running variable. After showing that our usual diagnostics are poorly suited to identifying this type of problem, we provide alternatives. We also demonstrate how the…
