Item A computational framework to examine public response of moral language on polarization following vigilantism incident(UTSA Graduate School, 2024-04-02) Kurumathur, Shalini Kapali; Najafirad, Peyman; Valecha, Rohit; Rao, H. RaghavIntroduction: ➢In August 2022, Kyle Rittenhouse fatally shot two men and wounded the third in Kenosha, Wisconsin. ➢Incidents of vigilantism provoke discourses related to moral values and may induce polarizing judgements in social media. ➢Moral foundations entail automatic gut-reactions of like and dislike when certain patterns are perceived in the social world, which in turn guide judgments expressed on social media. ➢The social media users could use moral languages of different vice and virtue. e.g., care (virtue) for the victim, harm (vice) the perpetrator ➢Such extreme judgements or attitude of right or wrong challenge the social cohesion in modern civil societies. ➢ We argue that understanding of polarization is incomplete without accounting for morality because moral foundations can predict attitudes on several social issues such as immigration, same-sex marriage and abortion. Purpose (or Objective, Goal): • How do public communicate moral language (virtue/vice) on social media following vigilantism incidents? • How does public’s vigilantism-related moral language (virtue/vice) on social media affect polarization?Item A Programmable and Participatory Sensing Testbed using Micromobility Vehicles(UTSA Graduate School, 2024-04-02) Jadliwala, Murtuza; Prasad, Sushil K.; Griffin, Greg P.; Maiti, Anindya; Molina, Nico; Wijewickrama, Raveen; Ashan M.K., Buddhi; Trinh, Khoi V.; Najafian, Nima; Khan, Ubaidullah; Sakib, Nazmus; Duthie, Christina; Patel, Ahmer; Kumar, PriyankaWhat is ScooterLab?

Although eradicated from the US in 1940s, CFT and Babesia are endemic to Mexico, Central and South America. CFT continue to infiltrate the US by crossing the border on wildlife or stray livestock and infest cattle herds. Avermectins are a class of anti-tick drugs administered to cattle to prevent and control tick infestation. Texas A&M University in collaboration with the US Department of Agriculture (USDA) conducted a doramectin (DOR) dosing study to evaluate how a double dose of DOR might extend the window of protection versus a single dose. We developed and validated a sensitive liquid chromatography/ tandem mass spectrometry (LC-MS/MS) method for analysis of the study’s samples. Presented here are an enhanced analytical method for this lipophilic class of drugs, the DOR plasma concentrations from the study, and the relevant pharmacokinetic parameters.Item An STM Study of Nickel Carbide and Copper Carbide Surfaces(UTSA Graduate School, 2024-04-02) Sutherland, Kevin; Sanchez, Jennifer; Xu, FangTransition metal carbides and nitrides (TMCs and TMNs) have shown unique properties for strongly binding reaction intermediates and d-block transition metals and have been used as heterogeneous catalysts. Due to the predicted strong binding with metals, TMCs and TMNs are also very promising support for single atom catalysts (SACs), which possess high atomic efficiency and high catalytic performance compared to traditional catalysts yet face a common challenge of thermal instability. Elucidating the structures of TMCs and TMNs at an atomic level and the interactions between the surface and adsorbate is a crucial fundamental question to address. Herein, well-defined transition metal carbide and nitride films are prepared on Cu(111) and Ni(111) surfaces as model catalyst supports for SACs (Figure 2). The insights gained from the model catalyst surfaces will be used to promote the development of catalytic reactions, such as aqueous phase methanol reforming (APRM).Item An Analysis of San Antonio's Vacant Building Program and the Impacts on Surrounding Neighborhoods(2020-04-18) Angel, SelinaThis report discusses how the City of San Antonio’s (COSA) Office of Historic Preservation (OHP) Vacant Building Program (VBP) has impacted surrounding properties and communities around neglected and abandoned structures since the program’s 2014 launch. The study area focuses on Dignowity Hill, a historic district and neighborhood that has the second-highest number of vacancies in San Antonio. After background research and statistical data was collected from VBP specialists, a market and demographic analysis was conducted on the study area. This data was retrieved from the National Historical Geographic Information Systems (NHGIS) website to determine the changes of the housing market and demographics before and after the VBP launch. Data shows that there is a correlation between the high number of vacancies and the revitalization of certain areas within Dignowity Hill. The analysis also concluded that most registered vacant properties lie near San Antonio’s downtown core. This area is experiencing the highest number of new constructions, which is bringing in diversity. The data also shows that there is a migration of the Hispanic population moving further away from the city core in Dignowity Hill. It is concluded that the VBP preserves the architectural aspects of the neighborhood but does not preserve the intangible elements -- therefore displacement and gentrification are bound to happen. The findings of this paper will help understand not only how programs like the VBP can help discover areas of redevelopment through vacancies within the city but also shed light on how these programs must find ways to preserve the intangible elements of a neighborhood as well.Item Applied Psychometrics (2nd place winner)(2022-04-07) Valdes, SaraCitation for image: Barbash, E.

Tranexamic and valproic acid have shown promise in improving coagulopathy and survival. This study explores different cell toxicity assays to evaluate the relationship with small molecules like tranexamic acid (TXA) and valproic acid (VPA). TXA exhibited dose-dependent cytotoxicity, with A549 cells resilient, while VPA showed heightened toxicity across all cell lines. These findings highlight the need for safer hemostatic agents, with TXA derivatives as a potential solution for combat hemorrhage control.Item Effects of Kelvin Helmholtz Instabilities in Planetary Magnetospheres (People's Choice Winner)(2022-04-07) Kumar, DineshItem Effects of Spatial Attention on Localization of Moving Sounds(UTSA Graduate School, 2024-04-02) Esparza, Lemira V.; Mock, Jeffrey R.; Golob, Edward J.Motion illusions: Representational Momentum and Lag: • Representational momentum (RM): a forward displacement (the sound traveled farther than it actually did) • Representational lag (RL): a backward displacement (the sound did not travel as far as it actually did) [Figure] RM and RL: Stimulus Duration: • Our prior experiments found RM with 2 secs durations, but RL with 1 sec durations. Attention Capture: • Greater RM for 2 sec vs 1 sec durations may be due to attention capture, which may delay/interfere with forward displacement (extrapolation). The time when attention capture is happening takes up a greater proportion of the stimulus duration (and trial time) in the 1 sec vs 2 sec stimulus. [Figure] Hypothesis: • Orienting attention to the sound’s onset location will increase RM and decrease RL. Attention: • Focused Attention: Endogenous attention: Top-down and goal-driven, can be activated with explicit instructions. Expectation: Implicitly learned patterns • Divided Attention: Exogenous attention: Bottom-up and sensory-driven, stimulus features capture attention [Figure]Item Electrochemical and Spectroscopic Investigation of Solvation and Complexation Effects on Titanium Redox Flow Battery Electrolytes(UTSA Graduate School, 2024-04-02) Ahmed, Sheikh Imran Uddin; Sankarasubramanian, ShrihariItem Evaluating the Effects of Loading Protocol on the Collapse Behavior of Lightly Confined Reinforced Concrete Columns(2021-04-08) Dolati, Seyed Sasan Khedmatgozar
