Evaluation of Eye Tracking Signal Quality for Virtual Reality Applications: A Case Study in the Meta Quest Pro
(2004) Aziz, Samantha; Lohr, Dillon J.; Friedman, Lee; Komogortsev, Oleg V.
We present an extensive, in-depth analysis of the eye tracking capabilities of the Meta Quest Pro virtual reality headset using a dataset of eye movement recordings collected from 78 participants. In addition to presenting classical signal quality metrics—spatial accuracy, spatial precision and linearity—in ideal settings, we also study the impact of background luminance and headset slippage on device performance. We additionally present a user-centered analysis of eye tracking signal quality, where we highlight the potential differences in user experience as a function of device performance. This work contributes to a growing understanding of eye tracking signal quality in virtual reality headsets, where the performance of applications such as gaze-based interaction, foveated rendering, and social gaze are directly dependent on the quality of eye tracking signal.
The Predictive Factors of Hospital Bankruptcy: A Longitudinal Analysis
(2024-03) Beauvais, Brad; Ramamonjiarivelo, Zo; Kruse, C. Scott; Fulton, Lawrence; Shanmugam, Ram; Sharma, Arvind; Tomic, Aleksander
This study develops an explanatory and predictive logistic model for hospital bankruptcy utilizing only 8 financial and hospital-level variables (drawing from 3,091 hospitals spanning 2008-2021). This robust tool may prove useful to healthcare leaders to more accurately assess and predict financial distress and bankruptcy in their own institutions in the future.
A Study of Weight Stigma, Body Appreciation, and Disordered Eating Behaviors among Promotores and Community Health Workers​ in Texas
(2024-03) Johnson, Cassandra M.; Biediger-Friedman, Lesli; Menge, Lindsey; Butler, Lauren; Lang, Julianne
Weight stigma, a form of discrimination, affects around 40% of the US population. Previous research suggests that weight stigma is: - negatively associated with body appreciation, an indicator of positive body image. - positively associated with disordered eating behaviors. Due to systemic inequities, racial and ethnic minority groups, including persons of Mexican heritage, may be more vulnerable to weight stigma. Promotores and community health workers (CHWs) serve a dual role as healthcare provider and community member, particularly in Hispanic communities in Texas (TX).  A formative study of weight stigma among promotores and CHWs is important to developing systems level, destigmatizing community-engaged interventions in TX.

Supporting Texas' health news ecosystem by creating resources, sharing expertise and training the next generation of data-driver reporters.
The Role of STEM Self-Efficacy, Research Confidence, and Belonging in Student Development: Fostering STEM Workforce Development Through an Institutional STEM Conference
(2024-03) Chang, Carolyn
The United States science, technology, engineering, and mathematics (STEM) workforce stimulates innovation and provides significant contributions to the nation. As science and technology advance, increasing demand for technically skilled employees follows. Today, almost a quarter (24%) of the U.S. workforce is employed in STEM occupations (NCSES, 2023).​ ​Representation of different groups based on sex, race or ethnicity, and disability status varies throughout the STEM workforce, with representation in STEM occupations unevenly distributed for these groups compared to all the working age population (NCSES, 2023). As the workforce demand in STEM continues to increase, along with a push for better representation among different groups, interventions to support STEM student career development are needed.​ Although research has demonstrated the impact of research experiences on degree and career plans, the benefits of attending and presenting research at professional conferences has been minimally investigated (Casad, et al., 2016). These few studies highlight the effectiveness of student professional conferences as an intervention that increases representation and success of underrepresented minority (URM) students in science. As travel to national conference is cost-prohibitive for many students, we sought out to investigate the impact that a student-focused institutional STEM conference intervention would have on student science self-efficacy, research confidence, sense of belonging in STEM. We also evaluated additional outcome measures related to education and career.
