Complex Segment Linkage Along The Sevier Normal Fault, Southwestern Utah, Benjamin Surpless, Wanda J. Taylor, Ilsa M. Schiefelbein Kerscher

Earth and Environmental Geosciences Faculty Research

Major normal fault systems are composed of segments that link as displacement accumulates, with linkage zone characteristics that reveal fault zone evolution. The steeply west-dipping Sevier fault zone in southwestern Utah, displays a complex fault network that developed between two long (>10 km), en echelon segments near the town of Orderville. Geologic map data and cross-sections of the transfer zone between the Mt. Carmel segment in the south and the Spencer Bench segment in the north reveal more than ten normal faults and four relay ramps displaying a range of geometries, including two relay ramps that display ramp-parallel folds. …

Enhancing Contractor Selection Through Fuzzy Topsis And Fuzzy Saw Techniques, Mohammadsoroush Tafazzoli, Ayoub Hazrati, Kishor Shrestha, Krishna Kisi

Microglial P2y6 Calcium Signaling Promotes Phagocytosis And Shapes Neuroimmune Responses In Epileptogenesis, Anthony D Umpierre, Bohan Li, Katayoun Ayasoufi, Whitney L Simon, Shunyi Zhao, Manling Xie, Grace Thyen, Benjamin Hur, Jiaying Zheng, Yue Liang, Dale B Bosco, Mark A Maynes, Zhaofa Wu, Xinzhu Yu, Jaeyun Sung, Aaron J Johnson, Yulong Li, Long-Jun Wu

The Brown Foundation: Institute of Molecular Medicine

Microglial calcium signaling is rare in a baseline state but strongly engaged during early epilepsy development. The mechanism(s) governing microglial calcium signaling are not known. By developing an in vivo UDP fluorescent sensor, GRABUDP1.0, we discovered that UDP release is a conserved response to seizures and excitotoxicity across brain regions. UDP can signal through the microglial-enriched P2Y6 receptor to increase calcium activity during epileptogenesis. P2Y6 calcium activity is associated with lysosome biogenesis and enhanced production of NF-κB-related cytokines. In the hippocampus, knockout of the P2Y6 receptor prevents microglia from fully engulfing neurons. Attenuating microglial calcium signaling through Calcium Extruder (“CalEx”) …

Assessing Effects Of Climate And Technology Uncertainties In Large Natural Resource Allocation Problems, Jevgenijs Steinbuks, Yongyang Cai, Jonas Jaegermeyr, Thomas W. Hertel

Department of Agricultural Economics Faculty Publications

The productivity of the world's natural resources is critically dependent on a variety of highly uncertain factors, which obscure individual investors and governments that seek to make long-term, sometimes irreversible, investments in their exploration and utilization. These dynamic considerations are poorly represented in disaggregated resource models, as incorporating uncertainty into large-dimensional problems presents a challenging computational task. In this paper, we apply the SCEQ algorithm (Cai and Judd, 2023) to solve a large-scale dynamic stochastic global land resource use problem with stochastic crop yields due to adverse climate impacts and limits on further technological progress. For the same model parameters …

In the upcoming years, there will probably be a considerable increase in the number of semi-autonomous vehicles on many US and European roads. Some experts even predict …

Skinny And Curvy And Muscular, Oh My! Examining Co-Occurring Appearance Ideals And Associated Disordered Eating In College Women, Laura E. Boyajian

USF Tampa Graduate Theses and Dissertations

Research examining appearance ideal internalization has primarily focused on the thin ideal, neglecting the growing importance of alternative appearance ideals (e.g., curvy, muscular). Qualitatively, women report that these ideals are not internalized in isolation, but instead, are internalized simultaneously. Importantly, the simultaneous internalization of appearance ideals may enhance the negative effects of appearance ideal internalization. The current study tested whether simultaneously internalizing diverse appearance ideals (i.e., thin, curvy, muscular) was associated with increased body dissatisfaction and disordered eating behaviors in a predominantly White (Study 1; N= 260) and racially/ethnically diverse (Study 2; N=264) samples of college-aged women. Participants reported the …

From Guns To Intimate Partner Violence: The Impact Of Power And Control, Meaghan E. Brown

USF Tampa Graduate Theses and Dissertations

Gun violence and intimate partner violence are pervasive public health concerns across the globe. Notably, previous literature has shown a positive relationship between gun ownership and intimate partner violence (IPV), even when a gun is not used during acts of IPV. Despite this established link, few studies to date have explored psychological mechanisms, especially feelings of and desire for power, that could explain this relationship among young men. Given that college students remain one of the most at-risk groups for both victimization and perpetration of IPV, examining the relationship between actual or intended gun ownership and IPV could close vital …

Trajectories Of Well-Being: Results From The Americans’ Changing Lives Study, Cassondra M. Lyman

USF Tampa Graduate Theses and Dissertations

There is considerable interest in elucidating the dynamics of well-being over long periods of time, including how well-being dynamics are influenced by depression. The Americans' Changing Lives (ACL) study has followed the health and well-being of a nationally representative sample of adults in the United States for 25 years (N1986 = 3,617; N1989 = 2,867; N1994 = 2,562; N2002 = 1,787, N2012 = 1,427). Leveraging data from the ACL study, the present investigation employed growth mixture models to identify unobserved subpopulations (i.e., latent classes) typified by change in well-being over time. Three predominant trajectories for well-being were identified: relative stability …

USF Tampa Graduate Theses and Dissertations

The purpose of this thesis was to evaluate the effectiveness and sustainability of a haptic-based intervention designed to reduce hand motions and, consequently, the risk of musculoskeletal disorders (MSDs) among operators in a manufacturing facility. The intervention involved using ergonomic gloves equipped with haptic feedback, intended to encourage proper hand motion and reduce unnecessary movements.

Over a six-month period, data was collected from operators wearing the haptic gloves, focusing on two key metrics: Duty Cycle and Motion Rate. These metrics were chosen to normalize the data, accounting for the variability in duration for each individual operator who wore the device. …

Incidence Of Reportable Exertional Heat Illness During Deepwater Horizon Cleanup, Fisher R. Morris

USF Tampa Graduate Theses and Dissertations

The purpose of this research was to explore the relationship between incidence of recordable exertional heat illness (EHI) and daily high wet bulb globe temperature (WBGTmax) or daily high Heat Index (HImax). Additionally, the effect of the previous day’s exposure to heat stress was investigated. Illness and injury records were collected during the Deepwater Horizon oil spill response. All OSHA recordable EHI cases were extracted for study. The highest estimated WBGT and HI on the day of incident were compared to the prior day. The overall incidence of recordable EHIs was 0.74 cases/100 FTE and the incidence for exposures ≥ …

“She’S On Her Way Up”: A Case Study Of Mercy Otis Warren And The Gendered Politics Of Commemoration, Sara Ann White

USF Tampa Graduate Theses and Dissertations

In 2001, a statue of eighteenth-century Bill of Rights advocate Mercy Otis Warren was erected on the Barnstable County Superior Courthouse lawn in Barnstable, Massachusetts. The story of the statue’s eventual placement is a fascinating case study of how the gendered politics of commemoration can play out over time in local communities. The saga of Warren’s commemoration is inextricably bound up with the history of efforts to commemorate Warren’s brother, James Otis Jr., and eventual arguments that Warren’s work deserved recognition in its own right. We first see gendered politics at play as Warren’s real accomplishments were consistently overshadowed by …

Getting To Green: International Financing For Green Energy Infrastructure In Developing Countries, Zach Fechter, Meagan Corser

Texas A&M Law Review

One of the symposium panels discussed financing clean energy projects. One panelist in particular expressed concern about how to build developing countries’ institutional capacity to utilize international financing for green energy. Global institutions like the World Bank and the International Monetary Fund (IMF) provide loans to developing countries conditioned on the countries privatizing and deregulating their energy sectors—otherwise known as austerity. While austerity measures may make sense in developed countries, this Comment argues that developing countries often lack the infrastructure needed to effectively utilize international financing precisely because the loans are conditioned on austerity. The World Bank and the IMF …

Plunging Children Into An Unconstitutional Purgatory: Why Texas Should Raise Its Standard Of Proof For Placing Children In Foster Care, Meagan Corser

Texas A&M Law Review

Texas currently allows Child Protective Services to remove children and place them in foster care for up to two years based only on probable cause of abuse or neglect. Removal itself is traumatic for children and foster care puts children at an unconstitutional risk of harm. Allowing courts to put children through the trauma of removal and foster care for years based only on probable cause departs substantially from the national norm for standards of proof, enables Texas to terminate parental rights at a high rate, and subjects children to a risk of harm for which the child welfare system …

All Works

This study focused on the nematicidal potential of sea urchin-like zinc oxide nanometrics (SUZN) against the root-knot nematode Meloidogyne incognita. XRD, SEM, UV-vis spectroscopy, TEM, and EDX have been utilized to characterize the SUZN. Various SUZN concentrations (150–750 ppm) were examined for their implications for M. incognita second-stage juveniles (J2s) and egg masses, including mortality as well as hatching inhibition. The largest J2s hatching inhibition (83.07%) was seen at 750 ppm SUZN after 48 hours of incubation, whereas the lowest hatching occurred at 150 ppm when compared to the control. SUZN illustrated increased nematicidal efficiency with increasing concentration and incubation …

Thermal Effects On The Voc-Sensitive Polydimethylsiloxane Holographic Gratings, Aleksandra Hernik, Faolan Radford Mcgovern, Patrick Iftime, Izabela Naydenova

Conference Papers

The imperative for monitoring volatile organic compounds (VOCs) emerges from their harmful impact on human health when inhaled excessively over a long term. Polydimethylsiloxane (PDMS), valued for its transparency and excellent flexibility, has already been demonstrated as a promising biocompatible and cost-effective transducer for optical VOCs sensing. Moreover, it facilitates further functionalisation with adsorbing materials to enhance sensitivity and selectivity for specific VOCs detection. We fabricated and examined PDMS-based surface diffraction gratings after exposure to selected VOCs, demonstrating different response for polar and non-polar molecules. Investigated gratings were prepared by replicating sinusoidal surface relief structures inscribed in acrylamide photopolymer using …

Understanding Political Rigidity: Exploring The Epistemic Underpinnings Of Political Ideology, Chad Mitchel Osteen

Dissertations

The ideology as motivated social cognition model conceptualizes conservatism in terms of two unique constructs: political conservatism and psychological conservatism. The former pertains to a predisposition to specific ideological beliefs (e.g., resistance to change), while the latter pertains to the psychological traits that are associated with particular ideologies (e.g., negativity bias). Experimental research demonstrates the mechanistic relationship of epistemic motivations and emergent political behavior. Much of the evidence lies in explicitly ideological outcomes. The current proposal seeks to test the fundamental assumption in this body of work. This is the assumption that increased epistemic motivation should lead to a preference …

Synthetic Assembly Of Antibacterial Agents And Metal Chelating Ligands, Zachary Joseph Liveris

Dissertations

The exploitation of chemical synthesis exemplifies the notion of bridging both innovation and curiosity for the strategic assembly of sophisticated molecular infrastructures. By exerting this continuously evolving and versatile tool, synthesis has been applied in the development and influence of a myriad of ligands, biological probes, and persists to direct pharmaceutical innovation and modern medicine alike. Since pathogenic multidrug-resistant (MDR) microbial strains remain to be a persistent threat to both clinical healthcare and society, the need to develop selective and efficacious antibacterial agents that can impede microbe pathogenicity and regulate cellular mortality is paramount. In contrast to pharmaceutical development, organic …

Understanding The Relationship Between Teacher Turnover And Student Success Across Ethno-Racial And Socioeconomic Demographics: An Analysis Of Massachusetts Public Schools, Jenna O'Leary

Master's Theses

Teacher turnover in the U.S. has risen over the past decades. Urban districts have faced some of the highest rates of turnover amongst their staff. However, scholars still debate the impacts of teacher turnover on student academic success. This study aims to better understand this relationship across both ethno-racial and socioeconomic student demographics, as well as school region type. To accomplish this, student test scores, across demographics, on the Next Generation MCAS state standardized test are observed in relation to teacher retention across three year cycles (2016-2017, 2017-2018, 2018-2019). Using correlation analysis and t-tests, it is found that there is …

Ct-To-Mri Synthesis For High-Dose-Rate Brachytherapy Treatment Planning, Rachel Nicole Gordon

Master's Theses

High-dose-rate (HDR) brachytherapy is a radiation treatment modality that places radioactive sources directly in cancerous regions. Radiation treatment planning for HDR prostate brachytherapy utilizes both CT and MRI to visualize the path of the radioactive source and the prostate gland, respectively. In this work, we propose GAN-CM, a method for conditional CT-to-MRI translation that is based on Generative Adversarial Networks (GANs). The proposed method uses the typical generator-discriminator design of GANs with a modified generator that incorporates semantic masks obtained from the domain image. The use of semantic masks allows GAN-CM to better capture the anatomical details and tissue characteristics …

What Do Extension And Public Health Educators Need To Address Substance Misuse?, Lisa Washburn, Karen Franck

Journal of Extension

Limited organizational capacity has hindered Extension’s ability to address substance misuse in communities. To inform capacity-building efforts, we obtained Extension educator and health educator feedback on opportunities, challenges and resource needs using the Delphi technique. Opportunities included collaboration and partnerships with local entities. Stigma, inadequate resources, and limited knowledge and skills of educators were challenges. Top resource needs were updated youth curricula, funding, and clear guidance on what educators can do and what should be referred externally. Findings provide insights to educator perceptions and suggest additional training and resources needed to implement evidence-based approaches to address substance misuse.
