Science-Related Rhetoric And Action By United States Presidents From 1977-2017, Amanda E. Shea

Interdisciplinary Studies

Presidential rhetoric and executive action have played an important role in shaping how scientific issues are presented to the American public. This project examined how United States presidents from Jimmy Carter through Barack Obama (1977–2017) employed science-related rhetoric and policy regarding climate science and reproductive health. Findings suggest that reproductive health remained a partisan issue throughout the study period, while climate science shifted from a largely bipartisan concern to a more partisan one over time. The results also indicate that presidential rhetoric and executive action were not always aligned, with several administrations using science-related rhetoric more extensively than corresponding policy.

Design For Repairability Demo, Wyatt Barnes, Andrew Petersen, Aaron Schiff, Ethan Dickson

Mechanical Engineering

Design for repairability is a growing focus in modern product development due to the widespread production of cheap electronic appliances with short service lives.
