How Far Is Too Far? Travel Planning Burdens In Autism Families, Risae Carlson, Daniel Olsen, Ruth Kerry

FHSS Mentored Research Conference

This study examines how the burden of planning and risk management influences travel distance and destination choice among families with a child on the autism spectrum. Survey data from Utah-based parents indicate that higher planning burden is associated with a preference for familiar, closer-to-home destinations and shorter travel distances. Despite these constraints, families report that travel remains highly valuable for bonding, fostering a sense of normalcy, and supporting developmental growth.

From Crown To Communism To Crown: Reconstruction In Budapest's Castle District Reveals How Heritage Is Selectively Rebuilt To Shape National Identity, Risae Carlson, Daniel Olsen

FHSS Mentored Research Conference

This project examines how reconstruction in Budapest’s Buda Castle District shapes perceptions of authenticity and historical memory. Following World War II destruction and socialist rebuilding, post-1989 reconstruction has emphasized a return to imperial-era aesthetics. Using visual and historical analysis, this study shows how different political periods have reshaped the same space to reflect shifting cultural priorities. While the district appears historically cohesive, many structures are reconstructed rather than preserved. This creates tension with UNESCO’s standards of authenticity and integrity. The findings suggest that reconstruction does not simply restore the past but actively reshapes it by prioritizing certain narratives while downplaying …

Where's Our Water? Invasive Saltcedar's Thirsty Trek Across The Shoreline Of Lake Mead, Mia R. Morgan, Joseph Penrod, Ruth Kerry

FHSS Mentored Research Conference

The prolonged megadrought in Southern Nevada has exposed thousands of acres of former lakebed at Lake Mead, creating an expanding frontier for the invasive shrub Tamarix ramosissima, commonly known as saltcedar. This hardy, non-native species rapidly colonizes the receding shoreline, siphoning up to 200 gallons of water per plant daily and outcompeting native vegetation. Utilizing high-resolution satellite imagery from 2020 and 2025, this research found that saltcedar coverage within a 5 km radius of the lake increased by approximately 76.7%.

Analysis of the spatial data indicates that while the total area of infestation has exploded, the average distance of …
