Linking Brain Structure To Function To Value-Based Choice, Josiah Leong

Publications and Presentations

What humans choose and how their brains make choices are central questions in psychology and neuroscience. Neuroimaging research is advancing models of functional brain activity that not only correlate with, but also predict, value-based choices in humans. Physiological research in animals suggests that monosynaptic axons structurally connect the brain circuits predictive of choice. However, similar structural connections have only recently been characterized in humans, and researchers are now starting to explore links from structural brain connections to functional brain activity to behavioral choice. In this lecture, Leong presents recent findings that link multimodal neuroimaging measurements to individual differences in value-based …

Sports Analytics: Putting The Fun Back Into Analytics, Walt Degrange

Operations Management Presentations

With the recent success of sports teams heavily using analytics (Dodgers, Patriots, Capitals, Warriors, Leicester City F.C.), does this mean that analytics has gained a foothold in the sports world? I use a k-means clustering model to determine if performance since 2015 in the four major US sports can support this question. And is there a career path that a high school student can use to become a sports analytics professional? This presentation attempts to answer that question by exploring all the areas of the application of analytics in sports. The final point the brief makes is that by using …

Using State Assessments To Increase Equity In G/T Identification, Sarah Mckenzie, Josh B. Mcgee, Charlene A. Reid, Bich Tran

Policy Briefs

In this brief, we explore the rate of identification of students as Gifted and Talented (G/T). In particular we examine the rate of identification for the highest achieving 3rd graders who scored in the top 5% statewide on state assessments in both Reading and Mathematics from 2015 to 2018 and the likelihood that they are identified G/T by 4th grade. Across five cohorts of 3rd to 4th grade students, we find that 30% of the highest achieving students are not identified as G/T. We find statistically significant differences in the likelihood that high achieving students from economically disadvantaged backgrounds are …
