Staffing Reductions, Visitor Sentiment, And Recreation Demand In U.S. National Parks, Rebekkah Adicoff Aug 2026

Staffing Reductions, Visitor Sentiment, And Recreation Demand In U.S. National Parks, Rebekkah Adicoff

Theses and Dissertations

Staffing changes in U.S. national parks have the potential to influence both visitor experience and recreation demand. This study examines how an abrupt system-wide staffing reduction affected visitor sentiment and visitation across the National Park System, while accounting for differences in park-level risk exposure. Using the February 2025 staffing reduction as a quasi-natural experiment, the analysis combines monthly park-level visitation data with TripAdvisor visitor reviews from January 2024 to August 2025. Sentiment scores derived from reviews measure perceived experience quality, while recreation demand is modeled using fixed-effects count models (Poisson and negative binomial) that control for seasonality and park characteristics. …

Profiles Of Body Image In Emerging Adults And Associations Across Sociocultural Influences, Alligrace Story Aug 2026

Profiles Of Body Image In Emerging Adults And Associations Across Sociocultural Influences, Alligrace Story

Theses and Dissertations

The Tripartite Influence Model of body image suggests that multiple sources of appearance-related pressures (i.e., family, peers, significant others, and media) impact body image and disordered eating behaviors via appearance-related comparisons and internalization of body-related ideals (i.e., thin-ideal internalization and muscular-ideal internalization). Previous research has shown support for the Tripartite Influence Model of body image among various demographic groups. The current study identified and examined profiles of emerging adults based on their reported body esteem and body appreciation. Body esteem was measured using the Body Esteem Scale for Adolescents and Adults (BESAA; Mendelson et al., 2001), and body appreciation was …

The Role Of Latinx And Hispanic Identity In The Presentation Of Hoarding Symptoms, Caitlyn Ashley Nix Aug 2026

The Role Of Latinx And Hispanic Identity In The Presentation Of Hoarding Symptoms, Caitlyn Ashley Nix

Theses and Dissertations

Although people who identify as Hispanic and Latinx make up approximately 19% of the United States population (U.S. Census Bureau, 2023), most research into hoarding disorder is comprised of White, non-Latinx samples. Thus, the current study investigated Hispanic and Latinx ethnicity as a predictor of several facets of hoarding disorder. Previous literature has shown lower risk for Hispanic and Latinx individuals in terms of several physical health outcomes when compared to individuals of similar socioeconomic status (Markides & Coreil, 1986), though mental health outcomes have more variation by subgroup (Barragán et al., 2020). Previous research has also shown that collectivistic …

Scan Statistics For Nonhomogeneous Poisson Processes: A Method For Cnv Detection, Asanka Rathnayaka Duwage Aug 2026

Scan Statistics For Nonhomogeneous Poisson Processes: A Method For Cnv Detection, Asanka Rathnayaka Duwage

Theses and Dissertations

This dissertation studies scan statistics for detecting localized changes in non-homogeneous Poisson processes. The motivating problem arises from genomic sequencing data, where tumor and normal read locations may differ over short regions due to copy number variation, while the underlying event intensity varies across the domain. In this setting, methods based on homogeneous Poisson process assumptions are not appropriate. The dissertation develops and studies scan-based methods for detecting local differences while accounting for non-homogeneous structure. Three related approaches are considered. The first develops a scan statistic for a nonhomogeneous Poisson process and uses extreme value calibration after transformation under the …
