Secondary School State Athletic Association Health And Safety Policy Development Processes, Susan Yeargin, Rebecca M. Hirschhorn, William M. Adams, Samantha E. Scarneo-Miller

Faculty Publications

Background: The National Federation of State High School Associations provides recommendations regarding health and safety policies; however, policy development is governed at the state level. Given interstate differences in governance, the primary purpose was to describe processes that State High School Athletic Associations (SHSAAs) utilize to develop a new policy. The secondary objective was to determine what methods associations use to implement new policies. Methods: A cross-sectional survey requested SHSAA (n = 51) representatives to report how athlete health and safety policies are introduced, revised, approved, and implemented within their state. The 22-question survey was developed to gather variables for …

Delong, Brian A. Schubert, Sophie Warny, Davin J. Wallace, Carrie M. Miller, Erin Culver-Miller, Michael J. Polito, Carl A. Reese, Kathryn Garretson, Kehui Xu, Grant L. Harley, Jeffrey Obelcz, Kelli L. Moran, Julian Traphagan, Douglas Jones, Alicia Caporaso

Faculty Publications

The southeastern United States Coastal Plain ecosystem contains baldcypress (Taxodium distichum) swamps and grass-dominated marshes. These ecosystems also occurred on the exposed continental shelf during lower sea levels but are rarely preserved due to the mechanically erosive nature of transgression and regression. Two presently marine sites on the northeastern Gulf of Mexico's continental shelf contain well-preserved woody terrestrial sediments that were the subject of previous studies. This study continues the investigation using geochemical (δ13C, δ15N, δ34S) and palynological characteristics of these formerly terrestrial sediments to determine if swamps and/or marshes existed at the time of deposition. The first site is …

A Simple Approach To Dealing With Partial Contestation, Ali Kagalwala, Thiago M.Q. Moreira, Guy D. Whitten

Faculty Publications

Objective: We propose a simple approach to dealing with partial contestation in models of multiparty elections. Methods: Our proposed approach is to add a tiny value to the vote share of parties that do not contest a district and then to include dummy variables identifying those districts in which parties do not compete. We can then estimate a single system of equations using a seemingly unrelated regression (SUR) approach and Aitchison's log-ratio transformation. In our SUR system, we interact the dummy variable for a party that partially contested districts with other predictors in the equation that uses the share of …

A (Dynamic) Investigation Of Stereotypes, Belief-Updating, And Behavior, Katherine Coffman, Maria Paola Ugalde Araya, Basit Zafar

Faculty Publications

Using a controlled experiment, we study the dynamic effects of feedback on decision-making across verbal skills and math. Before feedback, men are more optimistic about their performance and more willing to compete than women, especially in math. While feedback shifts individuals' beliefs and behavior, we see substantial persistence of gender gaps 1 week later. This is particularly true among individuals who receive negative feedback. Our results are not well-explained by motivated reasoning; in fact, negative feedback is more likely to be recalled than positive feedback. Overall, our results highlight the challenges involved in overcoming gender gaps in dynamic settings.

“It’S Not Ok To Not Be Ok”: Suicide, California’S Lanterman-Petris-Short Act, And The Constitution, Christina Strohmann

UC Law Constitutional Quarterly

Individuals who commit suicide are not incompetent or even making an irrational decision. Yet state laws, such as the Lanterman-Petris-Short Act in California, continue to allow mental health professionals to lock up suicidal patients in psychiatric facilities against the patient’s will. These commitments, however, are not always beneficial, and in many instances are detrimental to both the patient and the mental health professional. Patients can be traumatized from the experience, feel more suicidal from lack of hope and feelings of betrayal. Mental health professionals cannot effectively treat suicidal patients when providers are fearful of liability or when their patients refuse …

Development Of Anti-Fibrotic Agents For Potential Use In Glaucoma Filtration Surgery To Prevent Scar Formation, Nikhala Shree S

Theses and Dissertations

Glaucoma is the second leading cause of blindness with irreversible vision loss. It is marked by the degeneration of retinal ganglion cells, which results in optic nerve head damage. Intraocular pressure (IOP) is a prime risk factor of glaucoma controlled by various treatment regimens i.e., medication, laser, and/ or surgery. It is reported that longterm exposure to anti-glaucoma medications (AGM) may subtle the surgical success rate leading to postoperative fibrosis. Transforming growth factor beta (TGF-β) is a growth factor that plays an important role in the development of glaucoma and promotes fibrosis.

This study is aimed at developing peptides to …

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Herbicide sprayers are becoming larger and more efficient in applications in crop fields. A precise and efficient herbicide application is advantageous in effective weed control. New precision sprayers were introduced in hopes of reducing the amount of herbicide applied. Greeneye Technology and John Deere have developed precision sprayers for the detection of weeds in crop fields, which come equipped with a dual tank system that allows for two different herbicides to be separated from tank to tip. The objectives of this study were to evaluate the broadleaf and grass weed control efficacy of spot spray (SS) technology when applied in …

Triticale As A Source Of Resistance To Wheat Streak Mosaic Virus And Triticum Mosaic Virus, Marcos Winicius Goncalves De Souza

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Wheat streak mosaic virus (WSMV) and Triticum mosaic virus (TriMV) present a great threat to wheat production in the Great Plains area of the United States due to the loss of photosynthetic area causing reductions in crop yields. Effective control of these viruses is limited to a few available strategies including controlling volunteer wheat and using currently identified resistant genes to both the vector and viruses. While effective, these genes show temperature sensitivity and yield drag, and evidence that the vectors and viruses can overcome them has been found. Thus, new methods of genetic resistance are urgently needed. Field observations …

Optimization Of Chimeric Antigen Receptor T Cells For The Treatment Of Solid Tumors, Hailey Young, Ms

Student Papers, Posters & Projects

T cells have been called the “warriors of the immune system” and for good reason. T cells have many different functions including stimulating B cells to make antibodies; suppressing the immune response when it is no longer needed; killing of foreign, pathogenic, and cancerous cells and several other functions. Despite these key immune system functions, T cells sometimes are deregulated, and this can lead to an increased risk of cancer. Therefore, chimeric antigen receptor (CAR) T cells have been designed. CAR T cells are T cells that have been genetically engineered to possess a T cell receptor derived from murine, …

Comes In Waves: Clinical Overview Of Vibrio Species, Natalie M. Prosser, Ms

Student Papers, Posters & Projects

Earth’s oceans, despite their beauty and vast ecosystems, pose numerous threats to marine life and humans living along the coastline. Vibrio species (spp.) is a common species of oceanic bacteria native to coastal and brackish waters. This bacterium is capable of causing various degrees of human disease among different populations. Three clinically significant species of Vibrio include Vibrio vulnificus, Vibrio parahaemolyticus, and Vibrio cholera; all three species share virulence factors, but each are capable of causing varying degrees of vibriosis infections. Vibriosis infections include but are not limited to wound infections, necrotizing fasciitis, and gastroenteritis. In particular, …

Maggot Therapy And Its Clinical Application In The War Against Microbial Resistance, Nicholas Leidy, Ms

Student Papers, Posters & Projects

Antibiotic resistance poses a growing threat across the globe. The United Nations estimates that up to 10 million deaths by 2050 will be due to superbugs and antimicrobial resistance. Finding effective solutions has been obstructed by the expensive and time-intensive research and development process. Maggot therapy, however, has emerged as a promising, cost-effective approach to wound debridement or cleaning. This unconventional method takes advantage of the natural capabilities of maggots to effectively debride chronic, non-healing wounds, even those infected with multidrug-resistant bacteria. Through the utilization of proteolytic and digestive enzymes, maggots are able to break down necrotic tissue and promote …

Negotiating Police Reform, Cynthia Alkon

Faculty Scholarship

In the summer of 2020, after the murder of George Floyd, the national conversation around police reform intensified and was part of a conversation with students at Texas A&M University School of Law. Students wanted more discussion and teaching about police, police misconduct, police reform, and defunding the police. Following those discussions, I created a simulation on local level police reform that, as of this writing, I have used twice in my negotiation class. Simulations are helpful teaching tools in a variety of settings, including law schools. Simulations can be particularly useful to help students discuss difficult topics in different …

Improving Distributed Health Information Technology Integration Through Enriched Context In Sociotechnical System Components, Jeritt Thayer

Dissertations and Theses (Open Access)

The design and architecture of health information technology (HIT) are in the process of a transformative shift. Monolithic code bases, which are several systems intertwined into a single program, are being split into multiple distributed programs that communicate across information networks. Thus far, only sparse knowledge exists about the challenges of distributed HIT, and the interaction of these architectures with other factors of the sociotechnical system, such as clinical content, is not well understood. Existing sociotechnical models describe the components within a healthcare system and the connections between components, but the types of relationships between each component are underspecified. Within …

Beyond Four Walls: Outdoor Recess As A Complement To Classroom Engagement, Valerie Mulvenna

School of Education and Leadership Student Capstone Theses and Dissertations

This mixed-methods study examined the impact of increased outdoor recess on elementary students' classroom engagement following the implementation of Illinois' 2021 The Right to Play Every Day Act. The study is driven by two main research questions: (1) Does increased outdoor recess influence a student’s classroom engagement? (2) What are educators' perspectives on the implementation of the Act? Quantitative data was collected through classroom observations of 16 third-grade students over six weeks, measuring on-task behavior before and after recess periods. Qualitative data was gathered through semi-structured interviews with five elementary educators. While statistical analysis yielded inconclusive results regarding the relationship …

Preferential Crystallization Of (±)-Pinenyllithium·Tmeda, Alexander N. Erickson, Curtis Haltiwanger, Masoumeh Rahim, Charles M. Garner

Chemistry Faculty Research and Publications

(±)-Pinenyllithium·TMEDA or (tetra­methyl­ethylenedi­amine-κ²N,N′)(η³-6,6-di­methyl-2-methylenebi­cyclo­[3.1.1]hept­yl)lithium, [Li(C₁₀H₁₅)(C₆H₁₆N₂)], is readily pre­pared from β-pinene, butyl­lithium and TMEDA, and the racemic material pre­fer­entially crystallizes even from 96:4 (92% ee) mixtures of (−)- and (+)-β-pinene, respectively. The structure is monomeric, with the geminal-dimethyl bridge of the bicyclic structure shielding one face of the allyl system, restricting the lithium to the opposite face and preventing the Li–all­yl–Li aggregation observed with some other allyl­lithium systems. The symmetry of the allyl system, bond lengths, bond angles and out-of-plane deviations …

Optical Frequency Domain Reflectometry-Based High-Performance Distributed Sensing Empowered By A Data And Physics-Driven Neural Network, Zhaopeng Zhang, Wei Peng, Osamah Alsalman, Lingmei Ma, Jie Huang, Chen Zhu

Electrical and Computer Engineering Faculty Research & Creative Works

Optical frequency domain reflectometry (OFDR) based distributed strain sensors are the preferred choice for achieving accurate strain measurements over extensive sensing ranges while maintaining exceptional spatial resolution. However, the simultaneous realization of high spatial resolution, high strain resolution, large strain range, and an extended sensing range presents an exceedingly challenging endeavor. In this study, we introduce and experimentally demonstrate a data and physics-driven neural network-empowered OFDR system designed to attain high-performance distributed sensing. In our experiments, we successfully maintained an impressive sensing resolution of sub-microstrain (0.91 µε) alongside a sharp spatial resolution of sub-millimeter (0.857 mm) across a 140-m sensing …

The Relationship Between Monetary Policy And The Stock Market Cycle: An Empirical Study In Vietnam, Nhung Thuy Tran

The Indonesian Capital Market Review

The study examines the relationship between monetary policy and the stock market cycle in Vietnam. Using data from 2007 to 2022 and employing a VAR model, we estimate the impact of monetary policy factors on stock market cycle variables. The findings confirm a two-way causal relationship between monetary policy and the stock market cycle. However, the influence of cyclical fluctuations on the monetary policy transmission mechanism is weak, exhibits a lag, and predominantly occurs in the medium and long term. These results indicate that Vietnam's monetary policy requires time to absorb financial shocks and adjust to economic conditions. The study …

Post‐Fire Sediment Yield From A Central California Watershed: Field Measurements And Validation Of The Wepp Model, Amy E. East, Joshua B. Logan, Helen W. Dow, Douglas P. Smith, Pat Iampietro, Jonathan A. Warrick, Thomas D. Lorenson, Leticia Hallas, Benjamin Kozlowicz

AES Faculty Publications and Presentations

In a warming climate, an intensifying fire regime and higher likelihood of extreme rain are expected to increase watershed sediment yield in many regions. Understanding regional variability in landscape response to fire and post‐fire rainfall is essential for managing water resources and infrastructure. We measured sediment yield resulting from sequential wildfire and extreme rain and flooding in the upper Carmel River watershed (116 km2), on the central California coast, USA, using changes in sediment volume mapped in a reservoir. We determined that the sediment yield after fire and post‐fire flooding was 854–1,100 t/km2/yr, a factor of 3.5–4.6 greater than the …

Do Private Actors Have Rights Under The Wto? The Motivation For And (Inadequate) Implementation Of Gatt Article X, Adeet Dobhal, Petros C. Mavroidis, Lucas Moreira Jiminez, Sunayana Sasmal, Robert Wolfe

Faculty Scholarship

General Agreement on Tariffs and Trade (GATT) Article X has been consistently overlooked in literature even though it is a unique provision in the GATT-regime: it acknowledges standing for private actors who can challenge trade-related administrative action by World Trade Organization (WTO) members. This provision is an unusual instantiation of the need to provide transparency for private actors about state policy. It is equally eccentric in seeming to provide a right for private actors to challenge governments, albeit only before domestic fora. How did the GATT end up with this provision? And are these apparent private rights meaningful in practice? …

The Prohibition Of Annexations And The Foundations Of Modern International Law, Ingrid Brunk, Monica Hakimi

Faculty Scholarship

The international legal norm that prohibits forcible annexations of territory is foundational to modern international law. It lies at the core of three projects that have been central to the enterprise: (1) to settle title to territory as the basis for establishing state authority; (2) to regulate the use of force across settled borders; and (3) to provide for people within settled borders collectively to determine their own fates. Prohibiting forcible annexations is integral to each of these projects independently, and by tying them together, has had a transformative effect on the legal system as a whole. However, its significance …

A Comparative Evaluation Of Two Youth Mental Health Trainings For Volunteers, Monica M. Lobenstein, Shannon Sparks, Jennifer Park-Mroch, Danette Hopke, Jayna Hintz, Megan Suehring, Kea Norrell-Aitch, Karla Gearing, Michelle Gobert, Sheila Michels

Journal of Youth Development

Adolescence is a critical period for developing social and emotional habits important for mental well-being (Kessler et al., 2005). Half of all mental health conditions start by age 14, and the average delay between onset of symptoms and intervention is eight to ten years (Wang et al., 2007). Youth with mental health conditions are particularly vulnerable to social exclusion, discrimination, stigma, educational difficulties, risk-taking behaviors, and worsening physical health. Youth often do not get the help they need due to ongoing stigma and barriers in accessing mental health treatment. For example, in Wisconsin, 30% of the population live in a …

Utilization Of Probiotics To Compete With Clostridioides Difficile For Nutrient-Niches In A Variety Of In Vitro Contexts, April Elizabeth Johnson

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Clostridium difficile is a major threat to public health and primarily affects at risk groups such as elderly, immunocompromised individuals, and individuals on antibiotics. Many decades of research have been conducted to figure out ways to exclude or reduce C. difficile colonization and toxin production. Two major proposed mechanisms for colonization resistance are production of secondary bile salts and competition for nutrients.

In Chapter 2, we found that antibiotic treatment disrupted bile salt metabolism increasing the levels of the primary bile salt cholate and decreasing the levels of deoxycholate, a secondary bile salt. However, bile salts were not required …

Incorporating Human Movement Variability In Bimanual Multifrequency Coordination, Marilena Kalaitzi Manifrenti

Theses, Dissertations, and Student Creative Activity

Coordination is the organization of a system’s components to achieve collective behavior, whether within an individual or across systems. Coordination may be either monofrequency, the systems oscillating at the same frequency (e.g. 1:1), or multifrequency, the systems oscillating at unique frequencies (e.g. 1:3). Multifrequency coordination is typically described by the sine circle map (SCM); however, several limitations arise when describing human movement. Healthy young adults' movements exhibit Pink noise, a pattern in the timing of their actions that enables them to adapt flexibly to environmental changes by resulting in well-coordinated behavioral adjustments. The SCM fails to capture the natural variability …

Enacting Data Context: Fixing Meaning In Transparency Data Initiatives, Lindsay Poirier

Statistical and Data Sciences: Faculty Publications

This article documents the “context cultures” underpinning efforts to develop regulations for collecting and reporting data in a United States public database known as Open Payments. Open Payments is a dataset published annually by the US Center for Medicare and Medicaid Services that documents the transfers of value from pharmaceutical and medical device manufacturers to physicians, prescribing non-physicians, and teaching hospitals. In the article, I show context became a manifold concern as differentially-situated actors engaged in modes of public advocacy and social action around not only what data meant, but also what it meant to make data meaningful. I show …
