Sensitivity To Artificial Light And Sound In Bats Using Urban Landscapes, Aleana R. Savage

Graduate Theses/Dissertations

Anthropogenic activity has prompted range shifts, extirpations, and behavioral change of native wildlife. Although humans have long altered the landscape, recent (post-1950s) increases in land use intensification has significantly impacted wildlife habitat and biodiversity. As anthropogenic developments and disturbances compromise habitat, some species have begun to exploit urban areas. While there are some commonalities among synurbic species, such as generalist diets and high fecundity, not all urban wildlife share these characteristics. As urban areas expand, it will be essential to distinguish what drives unique species to select for urban habitat. The gray bat, Myotis grisescens, is an endangered species …

The Kinetic Modulation Of Α - Synuclein Fibrillation And Toxicity By 4-Phenylbutyric Acid, Kristos Awuah Baffour

Graduate Theses/Dissertations

ABSTRACT

The Protein misfolding and aggregation of alpha-synuclein (α-syn) into neurotoxic amyloids underlies the pathogenesis of neurodegenerative diseases such as Parkinson's disease (PD). 4-Phenylbutyrate (PBA), an FDA drug approved for treating urea cycle disorders, has garnered significant attention as a potential chemical chaperone for targeting alpha-synuclein (α-syn) aggregation. Using in vitro assays, we demonstrated that PBA treatment alters the pattern of α-syn aggregation, as evidenced by reduced formation of oligomeric species and its increased susceptibility to proteolytic cleavage under the influence of PBA. Proteinase K assay, surface plasmon resonance, and Nile red studies indicate that PBA interacts with the extensive …

Mining Contamination Of Legacy Deposits On Floodplains Along Turkey Creek, Western Border Of The Ozark Highlands, Hannah Riley Eades

Graduate Theses/Dissertations

Historical mining activities in the Tri State mining district in Southwest Missouri from 1850 to 1950 resulted in widespread metal contamination of stream sediments. Beginning in the 1840s, land disturbances associated with Euro-American settlement and agricultural expansion increased runoff and soil erosion rates resulting in the deposition of contaminated alluvium or legacy sediment on floodplains. This study assesses zinc (Zn) and lead (Pb) contaminated legacy deposits in cut-bank exposures along floodplains in Turkey Creek Watershed (119 km²) which drained mining areas in Missouri. Ore production histories were used date metal contamination profiles and calculate floodplain deposition rates in legacy deposits. …

Suitability Of Reintroduction As A Tool For The Conservation Of The Central American River Turtle (Dermatemys Mawii), Wesley O. Smith

Graduate Theses/Dissertations

The Central American River Turtle (Dermatemys mawii) has declined throughout its historical range to the point that it is critically endangered; the primary driver is overharvesting by humans for consumption. To help conserve this critically endangered turtle, a head-start program was established in Belize and introductions of head-started individuals have been considered to bolster populations. I released and studied hatchling and head-started juvenile Central American River Turtles during the summers of 2021 and 2022, respectively. The goal was to determine the suitability of hatchlings and juveniles for use in conservation reintroductions, along with elucidating aspects of the ecology …

Assessing The Effects Of Experimentally Contrived Negative Emotional Contexts On Affect, Willingness, And Impulsivity, Amanda Nicole Middleton

Graduate Theses/Dissertations

Emotions are a naturally occurring and unavoidable part of life. To investigate the role that negative emotional experiencing plays in transfer of stimulus function, relational behavior, and intervention effectiveness, this thesis combines and explores the implications of two manuscripts that examine the effects of negative emotional contexts. Specifically, the first chapter presents research demonstrating the ability of operant schedules of reinforcement and respondent relational training to result in acquired affective and willingness stimulus functions. A between groups design demonstrated that when paired with a frustration-inducing task, negatively valenced functions can be established for arbitrary stimuli, and when observational pairing was …

Gastrointestinal Parasite Prevalence Of Missouri Dogs Against Various Risk Factors, Mattie Cobban

Graduate Theses/Dissertations

Gastrointestinal parasites infect various mammalian species, including dogs, causing symptoms like diarrhea, lethargy, anemia, and possible death. Some gastrointestinal parasites possess zoonotic potential posing risk to dog owners, shelter workers, trainers, veterinary staff, groomers, and the public since dogs have access to public areas such as parks and stores. This study aims to understand the prevalence of gastrointestinal parasites of dogs in southwest Missouri under different environmental conditions. Fecal samples were collected from the Polk County Humane Society, local dog trials, and dog owners. The Mini-FLOTAC fecal flotation method was employed to quantify the type and number of parasite ova …

Role Of Ph And Plant Age On The Selection Of Rhizobial Endophytes In Soybean Root Nodules, Cole Alexander Roman

Graduate Theses/Dissertations

Soybeans form symbiotic relationships with nitrogen-fixing bacteria in their root nodules to acquire most of their nitrogen requirement; nitrogen is often one of the limiting nutrients in the soil. Members of the Bradyrhizobium, Sinorhizobium, Mesorhizobium, and Rhizobium genera can nodulate soybeans. Bradyrhizobium is preferentially selected over other types of rhizobia in varying environmental conditions and is often found in acidic soils. Sinorhizobium is often identified in the root nodules of soybeans in neutral and alkaline soil. So far, the potential role of soil pH on the selection of rhizobial endophytes with soybean root nodules is unknown. Likewise, …

Lost Time: Paying For Delays Associated With Labor Strikes And Traffic Jams (Chapter In A Coming Book: Research Handbook On Law And Time), Saul Levmore

Public Law and Legal Theory Working Papers

Waiting is often costly. In many settings, one party delays to impose costs on another. In other settings, delay yields a small gain while imposing significant costs on others who cannot easily bargain. Where the parties can bargain, at least one expects the other to relent and to bring about a settlement that is mutually beneficial. Inasmuch as time offers the opportunity to gather information, compare alternatives, and reach yet better bargains, law does not and should not simply discourage all delays. On the other hand, it is often the case that when parties delay before reaching a bargain, they …

Nature’S Relationship To Psychological Flexibility, Jake K. Sanders

Doctor of Psychology (PsyD)

Acceptance and commitment therapy has defined and successfully discovered methods of increasing psychological flexibility. Various methods of increasing psychological flexibility could be used as interventions. Contact with nature, in various forms, has been shown to increase and be related to many physical and mental health benefits. These benefits include things like mindfulness and other aspects of psychological flexibility. The question arises whether or not contact with nature is related to increases in overall psychological flexibility. The current study involved administering a questionnaire comprised of multiple existing measures, to primarily a college sample of 349 students. The answers were statistically analyzed …

Antisocial Personality Disorder And Trauma In Females, Marissa Lange

Doctor of Psychology (PsyD)

Antisocial personality disorder (ASPD) is a diagnosis reserved for individuals who feature deceitfulness, impulsivity, aggressiveness, recklessness, and irresponsibility. Evidence suggests that experiencing trauma is an etiological factor in developing antisocial traits in males. The prevalence of ASPD in the U.S. is three to one, male to female. However, research indicates females are substantially underdiagnosed due to exclusionary diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.-Text Revised; DSM-5-TR; American Psychiatric Association, 2013). The Personality Assessment Inventory (PAI) is a personality measure that features a conceptualization of ASPD that differs from the DSM-5-TR and includes more personality-specific …

Examining A Virtual Neuropsychological Battery For Older Adults, Robert W. Kessler

Doctor of Psychology (PsyD)

The restructuring of clinical service provision during the COVID-19 pandemic prompted neuropsychologists to reconsider telehealth options for patient care. Subsequent advances in teleneuropsychology (Tele-NP) research and practice have demonstrated that virtual assessment is not only practical, but also increases accessibility to neuropsychological services for the elderly, medically at-risk, and rural patients. In order to ensure services are in-line with professional standards of evidence-based practice, it is incumbent on research to demonstrate the validity of virtual assessment, as well as patient acceptability of Tele-NP findings. The objectives of this research project were three-fold. First, I aimed to determine the reliability of …

A Mixed-Methods Study Of Religious, Spiritual, And Psychological Change In Ireland, James D. Conway

Doctor of Psychology (PsyD)

Throughout the 20th century, over 90% of all individuals living in Ireland identified as Roman Catholic, but recent shifts have altered the country's religious landscape. According to the most recent national census, 70% of individuals still identify as Catholic (Central Statistics Office, 2023). However, they also reported a 187% increase in those claiming “no religion” over the last eleven years—making it now the second largest group (Central Statistics Office, 2023). This mixed-methods study investigated the factors behind these changes, surveying one hundred nine Irish individuals from sixteen counties using six validated measures, and conducting thirteen qualitative interviews. Quantitative and qualitative …

Using Lidar Data And Gis Analyses To Understand Looting Patterns In The Maya Biosphere Reserve, Chloe E. Sherwood

Graduate Thesis and Dissertation post-2024

This research examines looting activity at archaeological sites in the Maya Biosphere Reserve in Petén, Guatemala, focusing on areas both inside and outside established national park boundaries. The study covers sites occupied by the ancestral Maya from the Middle Preclassic to Terminal Classic periods (800 BC – AD 900), including El Mirador, Nakbé, and Wakná. This research uses LiDAR data and GIS analyses to identify looting clusters, comparing areas within the park to those outside, and investigates the relationship between looting activity and infrastructure such as trails, camps, and fresh water reservoirs.

Findings reveal that looting is more concentrated outside …

The Influence Of Natural And Anthropogenic Drivers On Estuarine Food Webs At Various Spatio-Temporal Scales And Levels Of Complexity, Michelle Shaffer

Graduate Thesis and Dissertation post-2024

Global coastal ecosystems support human life by providing critical services like food, water purification, and coastal protection, yet these ecosystems are among the most threatened due to natural and human-driven disturbances. The long-term maintenance and restoration of these ecosystems is a complex challenge for resource managers due to the wide range of factors affecting these ecosystems ecological condition over long timespans. Most studies in marine ecology evaluate ecosystem change over relatively short temporal scales (ago), often resulting in shifting baseline syndrome. To effectively manage and restore these ecosystems, resource managers must consider long-term ecosystem baselines.

A Critical Assessment Of The First Step Act’S Recidivism-Reduction Measures, Raquel Wilson

Dickinson Law Review (2017-Present)

The First Step Act of 2018 (“FSA”) is the most impactful federal sentencing reform of the past 40 years. While the Act represents a partial resurgence of the rehabilitative model of imprisonment, which had fallen out of favor decades before, it also represents a missed opportunity to fully integrate evidence-based rehabilitation programs for those offenders who pose the greatest risks to public safety.

The public has a strong interest in reducing recidivism, particularly among violent offenders, most of whom will be released from federal prison eventually. The FSA incentivizes participation in evidence-based, recidivism-reducing programs offered by the Bureau of Prisons …

Reshaping Government’S Fiduciary Role Under The 1992 Constitution Of Ghana, Rose Rameau, Abdul Baasit Aziz Bamba

Dickinson Law Review (2017-Present)

In Ghana and across many African States, the people—through the instrumentality of law or their respective Constitutions— have constituted their presidents trustees of the natural resources to be held in trust for the benefit of the people. With a few exceptions, mineral resource governance in Africa has been horrendous: Many African States have failed to leverage their natural resource endowments as a catalyst for much-needed socioeconomic development.

This Article analyzes the 1992 Constitution of the Republic of Ghana which provides that all public lands and natural resources in Ghana shall be vested in the President on behalf of, and in …

The Impossibility Of Religious Equality, Zalman Rothschild

Public Law and Legal Theory Working Papers

The Supreme Court has recently adopted a new rule of religious equality: Laws unconstitutionally discriminate against religion when they deny religious exemptions but provide secular exemptions that undermine the law’s interests to the same degree as would a religious exemption. All the Justices and a cadre of scholars have agreed in principle with this approach to religious equality. This Essay argues that this new rule of religious equality is inherently unworkable, in part because it turns on treating that which is religious the same as its secular “comparators.” But religion is not comparable to anything—neither in terms of its essence …

Retrenching Speech Protective Thresholds In Trademark Law, Jake Linford

Scholarly Publications

In their article, Raising the Threshold for Trademark Infringement to Protect Free Expression, Christine Haight Farley and Lisa Ramsey argue in favor of a speech-protective fair use test that would replace multiple tests applied by the U.S. Courts of Appeals when a defendant's alleged infringement has either informational or expressive elements. This Response explains why this raised threshold test is unlikely to be adopted following the U.S. Supreme Court's retrenchment of speech-protective thresholds in Jack Daniel's Properties, Inc. v. VIP Productions, LLC. That prediction is bolstered by the Court's likely holding in Vidal v. Elster. Readers persuaded that current defensive …

Expecting Better When You’Re Expecting: Empowering Mothers Through Occupational Therapy, Ann K. Landreville

Occupational Therapy Capstones

The maternal health crisis of the United States presents an opportunity to improve the level of care provided to the maternal population. A new standard of care must be established, going beyond decreasing maternal mortality and morbidity rates, but instead working to promote the health and well-being of mothers. While many well-recognized health professionals currently play a role on the interdisciplinary care team for postpartum mothers, occupational therapists are emerging in this field, proving they have a vital role in providing services that addresses the current gap in care. Many professions largely address physical health; occupational therapists have a holistic …

Sensory Home Programming Handouts, Taylor Ann Koopmeiners

Occupational Therapy Capstones

Background: Sensory processing is the way the brain and nervous system receive sensory information (Star Institute, 2023). When there are difficulties with processing sensory information, it is called Sensory Processing Disorder (SPD). Consequently, the inability to process sensory input results in affected motor and behavioral responses (Star Institute, 2023. This creates difficulty in participating in necessary tasks such as activities of daily living (ADLs), social participation, and school (Lane et al., 2019; Star Institute, 2023). Occupational therapists address these challenges by providing sensory activities in therapeutic sessions and as part of home programming (Gabriele, 2020). The goal of this scholarly …

An Occupational Therapy Program For First Responders Facing Trauma Fatigue And Work-Related Stressors Using Equine Facilitated Approaches, Kady Locke

Occupational Therapy Capstones

The proposed program is a mental health program, targeting meaningful daily occupations for the population of first responders facing trauma fatigue and antecedents of posttraumatic stress disorder symptoms related to stress from work. For individuals who serve as first responders, there is significant prevalence for trauma exposure, leading to trauma fatigue due to events encountered on the job. Mazur and Collins (2023) found that 80% of police and first responders experience traumatic events on the job and that 25% have experienced suicidal ideation due to impacts of trauma exposure. There is a lack of professional mental health services supporting this …

Breaking The Barrier To Leisure Engagement In Long-Term Care Facilities To Enhance Residents’ Health, Well-Being, And Quality Of Life, Callie M. Kleindl

Occupational Therapy Capstones

Title: Breaking the Barrier to Leisure Engagement in Long-Term Care Facilities to Enhance Residents’ Health, Well-being, and Quality of Life

Purpose: The purpose of this scholarly project was to promote leisure engagement for residents with dementia in long-term care (LTC) facilities to enhance their overall health, well-being, and quality of life (QOL).

Methodology: A thorough literature review supported the need for increased leisure engagement in LTC facilities for residents with dementia. Chronic conditions, such as dementia, impact a resident’s ability to engage in meaningful occupations which leads to occupational deprivation. In addition, a decline in leisure engagement has been found …

Addressing Health Care Needs Of Farmers In Rural Areas Through The Lens Of Occupational Therapy, Josie Lynn Huot

Occupational Therapy Capstones

Title: Addressing Health Care Needs of Farmers in Rural Areas through the Lens of Occupational Therapy

Background: Over three million farmers and farm laborers across the United States (U.S.) perform one of the most essential careers to support human life (Hildebrand et al., 2019; USDA, 2020). Farming is considered a highly dangerous job, putting farmers at risk for numerous health concerns, with a high prevalence of musculoskeletal injuries (Fethke et al., 2015; Hildebrand et al., 2019). Low back pain is a leading source of musculoskeletal pain, closely followed by neck pain, both of which are associated with the spine (Davis …

Making Strides: An Occupational Therapy Program Developing Work Readiness Skills In Adolescents With Aces, Using Equine And Barn Tasks., Lauren Alexis Fischer

Occupational Therapy Capstones

Background: The Center of Disease Control and Prevention (CDC, 2022) defines adverse childhood experiences (ACEs) as any traumatic event that occurs from birth to 18 years. ACEs can lead to various issues in the child's future, such as health problems, mental illness, substance abuse, and challenges with education and employment (CDC, 2022). Associated barriers that inhibit at-risk youth when transitioning into the workforce include lack of work skills, habits, knowledge about labor rights, realistic job opportunities, and how to pursue employment (Ivzori et al., 2020). Increasing support in their pre-vocational skills can increase their success in employment. Rhew et al. …

Methods That Support The Validation Of Agent-Based Models: An Overview And Discussion, Andrew Collins, Matthew Koehler, Christopher Lynch

Engineering Management & Systems Engineering Faculty Publications

Validation is the process of determining if a model adequately represents the system under study for the model’s intended purpose. Validation is a critical component in building the credibility of a simulation model with its end-users. Effectively conducting validation can be a daunting task for both novice and experienced simulation developers. Further compounding the difficult task of conducting validation is that there is no universally accepted approach for assessing a simulation. These challenges are particularly relevant to the paradigm of Agent-Based Modeling and Simulation (ABMS) because of the complexity found in these models’ mechanisms and in the real-world situations they …

Nanosecond Pulsed Electric Fields Increase Antibiotic Susceptibility In Methicillin-Resistant Staphylococcus Aureus, Alexandra E. Chittams-Miles, Areej Malik, Erin B. Purcell, Claudia Muratori

Bioelectrics Publications

Staphylococcus aureus is the leading cause of skin and soft-tissue infections (SSTIs). SSTIs caused by bacteria resistant to antimicrobials, such as methicillin-resistant S. aureus (MRSA), are increasing in incidence and have led to higher rates of hospitalization. In this study, we measured MRSA inactivation by nanosecond pulsed electric fields (nsPEF), a promising new cell ablation technology. Our results show that treatment with 120 pulses of 600 ns duration (28 kV/cm, 1 Hz), caused modest inactivation, indicating cellular damage. We anticipated that the perturbation created by nsPEF could increase antibiotic efficacy if nsPEF were applied as a co-treatment. To test this …

Intersectionality Matters In Food And Drug Law, Colleen Campbell

University of Colorado Law Review

Feminist scholars critique food and drug law as a site of gender bias and regulatory neglect. The historical exclusion of women from clinical trials by the FDA prioritized male bodies as the object of clinical research and therapies. Likewise, the FDA’s prior restriction on access to contraceptive birth control illustrates how patriarchal and paternalistic attitudes within the Agency can harm women’s reproductive health. However, there is little analysis of how race and gender intersect in this domain. This Article uses the regulation of skin-lightening cosmetics products to illustrate why and how intersectionality matters in food and drug law. While the …

Immigration Detention Abolition And The Violence Of Digital Cages, Sarah Sherman-Stokes

University of Colorado Law Review

The United States has a long history of pernicious immigration enforcement and surveillance. Today, in addition to more than 34,000 people held in immigration detention, Immigration and Customs Enforcement (ICE) shackles and surveils an astounding 376,000 people under its “Alternatives to Detention” (“ATD”) program. The number of people subjected to this surveillance has grown dramatically in the last two decades, from just about 1,700 in 2005. ICE’s rapidly expanding Alternatives to Detention program is a “digital cage,” consisting of GPS-outfitted ankle shackles and invasive phone and location tracking. Government officials and some immigrant advocates have characterized these digital cages as …

A First Amendment Failure: Surrendering To Science Misinformation For Bioengineered Foods, Casey J. Nelson

University of Colorado Law Review

Government-compelled commercial disclosures are not unfamiliar to consumers. Common labels include nutrition facts and ingredient information. The National Bioengineered Food Disclosure Standard, which took full force at the start of 2022, is of a different nature. The new law requires all manufacturers, all importers, and certain retailers of bioengineered foods to disclose on the food’s packaging that it has been produced with bioengineering technology. Even so, a large swath of the public is ignorant of “bioengineering’s” true meaning and bioengineering technology’s true quality. The politically charged and fact-lacking debate on bioengineered foods renders this standard an impermissible coercion of speech …
