Familiarity Moderates Education Level Of Stigma For Professional Efficacy Of Treating Mental Illness, Jason J. Burrow-Sanchez, Shawnda Schroeder, Thomasine Heitkamp, Brian Urlacher, Sharon Cook, Paula Bennett, Carolina Corrales

Indigenous Health Faculty Publications

Background: About one in five adults in the United States experience any mental illness (AMI) whereas 14.2 million experience serious mental illness (SMI). The perception of stigma among these individuals can be associated with care seeking behavior and treatment adherence.

Purpose: Two factors that mitigate stigma are familiarity with someone experiencing AMI/SMI and general level of education. Heretofore, these factors have not been tested together to determine if familiarity moderates the relation between level of education and stigma of professional efficacy for treating mental illness.

Methods: In fall 2020, an online survey in the state of Utah measured 1,300 adults’ …

Equiangularity From Compatible Orthobiangularity, Tyler J. Myers

Theses and Dissertations

An equiangular tight frame (ETF) is an equal norm sequence of vectors in a Hilbert space whose coherence achieves equality in the Welch bound. Such sequences necessarily have minimal coherence and thus are, in some sense, as "spread out" in space as possible. ETFs have a variety of applications, such as compressed sensing and waveform design. The main problem in the study of ETFs is determining the pairs (D, N) for which an ETF with N vectors in a D-dimensional space exists. Real ETFs are moreover equivalent to a special subset of a well-studied class of graphs known as strongly …

Rotating Scatter Mask System Optimization Study For Determining Optimal Image Recreation, Seth L. Grover

Theses and Dissertations

The Rotating Scatter Mask (RSM) system is a radiation imaging technology currently limited by the mask design and governing identification algorithm parameters. To optimize the RSM design, Dakota—an optimization software—was integrated with a ray tracing code that simulates particle interactions with the RSM detector, and with the Locally Competitive Algorithm (LCA), which reconstructs the source image based on the ray tracing code’s Detector Response Matrix (DRM). Since the original ray tracing code was developed in MATLAB, it was translated into Python to improve compatibility with both Dakota and LCA. The Python version of the ray tracing code was then integrated …

Fused-Silica Microelectromechanical Systems For Relative Gravimetry, Ethan Doerstling

Theses and Dissertations

Gravimeters are devices that measure gravitational acceleration which can be used by the United States Air Force (USAF) in the areas of navigation and remote sensing. Fused-silica microelectromechanical systems (MEMS) devices offer capabilities to make inexpensive relative gravimeters with higher thermal stability than common silicon devices while maintaining good gravitational sensitivity. The fused-silica devices in this research were designed, simulated, fabricated, and tested to observe their performance as gravimeters. The devices exhibit properties of highly sensitive accelerometers but the current designs do not qualify as gravimeters. This study provides information to improve the sensitivity and stability of these fused-silica MEMS …

Leveraging Large Language Models (Llms) For Automated Generation Of Sysml V2 State Machines In Guidance, Navigation, And Control (Gnc) Systems, Andrea Louise Ames

Theses and Dissertations

Modern defense systems continue to grow in complexity, placing increasing pressure on engineering workflows to be faster and more adaptable. While Model-Based Systems Engineering (MBSE) with the emerging SysML v2 standard provides a framework for capturing system behavior, its practical use is often limited by the expertise and time required for manual modeling. This research investigates whether large language models (LLMs) can help overcome that barrier by automatically generating SysML v2 state machines from Guidance, Navigation, and Control (GNC) textual inputs. Three LLM Flowise-based models were developed and evaluated: the Structured Transformation Model (STM), which uses a structured extraction and …

Conducting Background Checks In The Corporate Security Environment, Alan Saquella

Publications

In the current threat landscape, the background check has become a critical frontline defense in protecting corporate assets, brand integrity and personnel safety. But as any security leader will tell you, the traditional background check — focused on criminal history, employment verification and references — has limitations, especially in today’s regulatory environment.

Federal and state restrictions continue to erode the depth and scope of what can be legally reviewed, and meanwhile, insider threats and deceptive candidates are becoming more sophisticated. In this context, it's no longer about whether to conduct background checks — it's about how to conduct them effectively, …

Infrastructure From Below: Mediasi Dan Politik Pembangunan Infrastruktur Air Di Kota Balikpapan, Muhammad Althaf Nandiati Yusfid

Antropologi Indonesia

The city of Balikpapan is experiencing a water crisis. The discrepancy between the city's water supply and Balikpapan's demography put pressure towards the city's capability of supporting its own citizens. This issue is exacerbated by the development of Indonesia's New Capital (IKN) which is located just outside Balikpapan. Therefore, the development of water infrastructure is imperative for the city. Yet, there's no recent visible development of water infrastructure in the city. However, I argue that water infrastructure development actually exists, though in a subtle form. The informal water suppliers that are prevalent in the city is tied with how the …

Planning A New Paradigm: Tribal Co-Stewardship And Federal Public Lands Planning, Monte Mills, Martin Nie

Articles

Planning is a critical part of the federal government’s management of the nation’s public lands. Over the last half century, Congress has mandated that each of the four major public land management agencies; the U.S. Forest Service, the Bureau of Land Management, the U.S. Fish and Wildlife Service, and the National Park Service, develop and rely on plans to guide their oversight of public lands and resources. Virtually every activity or decision affecting these public lands can be traced back to language in—or missing from—a plan. But, despite the importance of planning, the process by which each agency develops and …

The New Redlining: How Progressive Policies Restrict The Development Of Housing Supply And Perpetuate America's Racist Property Law Past, Steve Calandrillo, Kelsey Dunn

Articles

Recent scholarship has exposed America’s racist property law past. During the twentieth century, decades of deliberate state-sponsored discrimination (a.k.a., “Redlining”) made homeownership—and the accumulation of wealth—more difficult for people of color. In 1948, the Supreme Court outlawed these practices in the seminal case, Shelly v. Kraemer. However, the damage had been done, and has proven to be long-lasting. Redlining slowed economic mobility for people of color and exacerbated the racial wealth gap. As a result, America is in the midst of an affordable housing crisis that disproportionately impacts people of color.

The Equal Protection-Fourth Amendment Shell Game: An Essay On The Limited Reach Of The 2023 Affirmative Action Cases, The Fourth Amendment, And Race Beyond Skin Color, David B. Owens

Articles

In striking down race-conscious admissions at Harvard and the University of North Carolina, the Supreme Court used lofty rhetoric about the importance of ending race discrimination, even calling the command of Equal Protection “universal.” In two ways, this Essay explores the legal and practical limits of the affirmative action cases and illustrates how the Court’s claimed concern about race discrimination rings hollow. First, this Essay discusses state actors permitted to use race in their decision-making: the police. Unlike elite universities whose policies are subject to exacting scrutiny, the Supreme Court permits police to use race when deciding whom to seize …

Summaries Of Arkansas Cotton Research 2024, Fred M. Bourland

Arkansas Agricultural Experiment Station Research Series

Planted cotton acreage in Arkansas increased in 2024 to 670,000 planted acres, which was 160,000 acres more than in 2023 when Arkansas producers planted approximately 510,000 acres of cotton. A wet spring, and two hurricanes in three weeks in late summer/early fall led to a slight decrease in harvested acres that culminated in a final number of 640,000 (https://www.nass.usda.gov/Quick_Stats/Ag_Overview/stateOverview.php?state=ARKANSAS). Producers harvested 640,00 acres of cotton, which ranked third nationally, behind Texas and Georgia (https://downloads.usda.library.cornell.edu/usda-esmis/files/k3569432s/nk324887m/qn59s0097/cropan25.pdf). The total harvested acreage is the greatest amount since 680,000 acres in 2011. The average cotton yield in Arkansas in 2024 was …

The Macrophage Sterol Transport Protein Orp2 Promotes Cholesterol Efflux And Prevents Foam Cell Formation And Atherosclerosis, Xiaowei Wang, Kenan Peng, Yudi Zhao, Liwen Qiu, Chenxi Liang, Yaqian Dou, Qianqian Dong, Xiaoting Ma, Jinye Tang, Yidan Ma, Lin Liu, Mingqi Zheng, Hongyuan Yang, Mingming Gao

Faculty, Staff and Student Publications

Cholesterol-loaded macrophage foam cells are a key feature of atherosclerotic plaques. Oxysterol-binding protein-related protein 2 (ORP2) facilitates the transport of cholesterol from lysosomes to the plasma membrane in cultured cell lines. However, the role of ORP2 in macrophages and its involvement in atherosclerosis remain unclear. In this study, we found ORP2 expression was reduced in atherosclerotic vessels and in macrophages exposed to oxidized LDL (ox-LDL). Myeloid-specific human ORP2 overexpression (hORP2MOE) mice were generated and crossed with atherosclerotic-prone ApoE−/− mice and then fed a high-fat diet (HFD) to induce atherosclerosis. Our results showed that myeloid-specific hORP2 overexpression significantly reduced the atherosclerotic …

Time To Weight Plateau With Tirzepatide Treatment In The Surmount-1 And Surmount-4 Clinical Trials, Deborah B Horn, Scott Kahan, Rachel L Batterham, Dachuang Cao, Clare J Lee, Madhumita Murphy, Sylvia Gonsahn-Bollie, Farai Chigutsa, Adam Stefanski, Julia P Dunn

Faculty, Staff and Student Publications

The rate of weight reduction during obesity treatment declines over time and eventually reaches a weight plateau. We investigated factors associated with time to weight plateau (TTWP) in tirzepatide-treated participants with obesity or overweight in a post-hoc analysis of SURMOUNT-1 and SURMOUNT-4 trials. Participants adherent to tirzepatide treatment and achieving ≥5% weight loss by primary endpoint (week 72 SURMOUNT-1; week 88 SURMOUNT-4) were included. Weight plateau was defined as a weight change < 5% over a 12-week interval and all subsequent 12-week intervals. TTWP was time from randomization to the start of the first 12-week interval. Association between baseline characteristics and TTWP was assessed. Overall, 1438 participants in SURMOUNT-1 and 259 in SURMOUNT-4 were included. Across BMI categories (overweight, class I, II, and III), median TTWP in SURMOUNT-1 was 24.3, 26.0, 36.1, and 36.1 weeks, respectively (p < .05, class II and III vs. overweight). By week 72, 90.2%, 88.9%, 87.6%, and 87.8% of participants in SURMOUNT-1 had reached a weight plateau across respective BMI categories [Correction added on 22 January 2025, after first online publication: The "72%" has been changed to "72" in this version.]. Higher doses of tirzepatide (10/15 mg), younger age, and female sex were more likely to reach a weight plateau later. Results in SURMOUNT-4 were similar. In this post-hoc analysis, most participants reached a weight plateau by week 72. Higher doses of tirzepatide, younger age, and female sex were associated with a longer TTWP. Further research into modifiers of weight reduction phases with tirzepatide may inform treatment decisions for its use in chronic weight management.

In this case series, we shed light on the intricate landscape of seizure management and neuropsychiatric comorbidities in five individuals with frequent seizures (often weekly) and ultra-refractory epilepsy (defined as resistance to more than six different antiseizure medications, including failed epilepsy surgery) following catastrophic encephalitis. Four out of five patients …

Expanding The Clinical Spectrum Of Porokeratosis Ptychotropica, Brooke R Bartley, Dylan R Maldonado, Steven Mays, Ronald P Rapini

Faculty, Staff and Student Publications

Porokeratosis ptychotropica (PP) is a rare variant of porokeratosis, typically presenting as pink to brown hyperkeratotic plaques in the gluteal cleft and buttocks, defined histologically by multiple cornoid lamellae. Diagnosis of PP is challenging due to its clinical overlap with other dermatologic conditions and inconsistent terminology in the literature. This case report describes a 47-year-old woman exhibiting clinical and pathological features of PP but with a more diffuse presentation than previously documented. The case emphasizes the diagnostic complexities of PP, particularly in atypical presentations, and highlights the critical role of histological examination in distinguishing it from other porokeratoses.
