A Portfolio In Creative Writing, Cooper Golden

Theses

When I began writing my thesis project, it was difficult to figure out which stories I had written during my time at UNA would fit. Before, during, and even between semesters, I wrote several stories that might have been good selections, but as they weren’t school assignments, I couldn’t include them. However, making my project has allowed me to go back to three stories and not only revise but improve on what I had written. Something else that I’ve noticed in my project is how diverse the genres of my stories have been. For example, in two stories I focus …

The Physiological And Behavioral Effects Of A Centrally Administered Oxytocin Receptor Antagonist On Maternal Buffering In Infant Guinea Pigs, Kendra A. Carter

Browse all Theses and Dissertations

This study investigates the role of endogenous oxytocin (OT) in maternal buffering of infant stress responses in guinea pigs. Infants received intracerebroventricular infusion of an oxytocin receptor antagonist (OTA) or artificial cerebrospinal fluid (aCSF) immediately before being placed with the mother in a novel environment for 60 minutes. Blood cortisol levels and behavioral responses, including vocalizations and crouching, were measured throughout the testing period. Results indicate only a significant effect of time, with cortisol levels increasing with time spent in the novel environment. Otherwise, no significant differences were observed either physiologically or behaviorally between aCSF and OTA conditions. This study …

Retracing Their Tracks: The Rediscovery And Memorialization Efforts Of The National Orphan Train Project, Joanna Lockwood

Master's Theses or Doctor of Nursing Practice

Between 1854 and 1929, the placement system that became known as the orphan trains in modern scholarship, removed neglected and orphaned children from the dangerous streets of New York City and attempted to place them into homes across America that would benefit their futures. While this charity-run program was well-intentioned, the estimated two hundred fifty thousand children of the orphan trains experienced a mix of encounters upon their placements. Although many homes provided a caring environment for these children, others did not. After years of struggle during their early childhood, numerous children had not only lost their parents and were …

Examining The Relationship Between Toddlers’ Sleep Patterns, Negative Parenting, And Executive Function, Morgan Elizabeth Harris

Electronic Theses and Dissertations

Negative parenting can often be described as having three domains (i.e., laxness, verbosity, and over-reactivity, Arnold et al., 1993; Rhoades & O’Leary, 2007), which may have relations to toddlers’ behaviors, like executive function (EF) and sleep. However, this field is understudied, especially in early childhood development. One possible explanation for the lack of research in this field is that it can be difficult to study executive function in toddlers due to variability in the stability of regulatory behaviors and emerging regulatory abilities at this age range. Although positive sleep patterns (e.g., quality and quantity) have been linked to executive function, …

Astrocytic Mitochondrial Transfer To Brain Endothelial Cells And Pericytes In Vivo Increases With Aging, Gopal V. Velmurugan, Hemendra J. Vekaria, Samir P. Patel, Patrick G. Sullivan, W. Brad Hubbard

Neurology Faculty Publications

Intercellular mitochondrial transfer (IMT) is an intriguing biological phenomenon where mitochondria are transferred between different cells and notably, cell types. IMT is physiological, occurring in normal conditions, but also is utilized to deliver healthy mitochondria to cells in distress. Transferred mitochondria can be integrated to improve cellular metabolism, and mitochondrial function. Research on the mitochondrial transfer axis between astrocytes and brain capillaries in vivo is limited by the cellular heterogeneity of the neurovascular unit. To this end, we developed an inducible mouse model that expresses mitochondrial Dendra2 only in astrocytes and then isolated brain capillaries to remove all intact astrocytes. …

Using Digital Pathology To Analyze The Murine Cerebrovasculature, Dana M. Niedowicz, Jenna L. Gollihue, Erica M. Weekman, Panhavuth Phe, Donna M. Wilcock, Christopher M. Norris, Peter T. Nelson

Neurology Faculty Publications

Research on the cerebrovasculature may provide insights into brain health and disease. Immunohistochemical staining is one way to visualize blood vessels, and digital pathology has the potential to revolutionize the measurement of blood vessel parameters. These tools provide opportunities for translational mouse model research. However, mouse brain tissue presents a formidable set of technical challenges, including potentially high background staining and crossreactivity of endogenous IgG. Formalin-fixed paraffin-embedded (FFPE) and fixed frozen sections, both of which are widely used, may require different methods. In this study, we optimized blood vessel staining in mouse brain tissue, testing both FFPE and frozen fixed …

The Effect Of State Anxiety On Working Memory Updating, Alexandra L. Mastrangelo

PCOM Psychology Dissertations

Anxiety impairs cognition by operating to alter processing efficiency. When anxiety impairs efficiency, the capacity of working memory (WM) is confined especially for individuals who concurrently experience higher levels of anxiety (Yang et al., 2018). The updating function is a crucial process that operates within WM to replace and modify older with novel information to carry out complex cognitive tasks. However, if interference accrues from previously learned information (known as proactive interference, or PI), removing information from WM becomes more difficult. Because the relationship between state anxiety (SA) and WM is less understood compared to trait anxiety (TA), this study …

Mallory V. Norfolk Southern Railway Co., Due Process And Strange Bedfellows, Michael Vitiello, Daniel Croxall

Missouri Law Review

[As the 2022 Supreme Court term waned, the press and public waited with trepidation or excitement for noteworthy cases that addressed important policy questions, including affirmative action, student loan forgiveness, and conflicts between religious freedom and gay rights. Fewer people shared the concerns of Civil Procedure scholars who anxiously awaited the Court’s decision in Mallory v. Norfolk Southern Railway Co. For over a decade, the Court found that states violated due process in asserting personal jurisdiction over various defendants despite the lack of any meaningful burden on the defendant’s ability to defend against claims in the plaintiff’s choice of forum. …

Food Procurement: An Essential Ingredient To Mitigating Climate Change And Enhancing Public Health, Chloë Waterman, Rachel Clark, Steven L. Schooner

GW Law Faculty Publications & Other Works

This short article addresses a critical, but often underappreciated, aspect of the evolving suite of efforts to reduce greenhouse gas (GHG) emissions: food and agriculture systems, which account for at least a quarter of GHG emissions and more methane emissions than any other sector. The article invites government leadership to become more intentional in focusing on sustainable food procurement as a key strategy to mitigate climate change. The authors argue that public food procurement can – and should – be leveraged to generate a wide range of cascading social benefits beyond mitigating climate change and improving public health, including worker …

Regulating Producers By Randomizing Consumers, Michael B. Abramowicz

GW Law Faculty Publications & Other Works

Consumer law aims to empower consumers with accurate information and to protect them from misinformation. For complex goods and services, however, mandated disclosure laws and other consumer law tools have had only limited success in helping consumers project their satisfaction and costs. Market responses, such as ratings, have limitations that have prevented them from compensating adequately for consumer law’s shortcomings. This Article describes how regulators could improve measurements of quality and cost by borrowing a tool from drug law: randomization. In designated markets, consumers who accept an incentive to volunteer would be randomized among two or more choices, and the …

Mandated Reporting And The Legal Educator's Duty, Cori Alonso-Yoder, Eve Rips

GW Law Faculty Publications & Other Works

As lawyers and educators, law teachers often navigate systems that have failed to account for the needs of the communities that are subject to regulation. These same systems generally fail to appreciate the hybrid role exercised by lawyers who face competing demands as educators. A key example is the tension that exists for legal educators who engage students in clinical and other forms of experiential learning where questions of abuse or maltreatment of vulnerable community members may trigger mandated reporting to government officials. These laws can place legal faculty in the fraught position of needing to reconcile statutory reporting mandates, …

Pixels Or People: A Comparison Of The Differenital Effects Of Animated And Human Video Models On Exercise Behaviors For Hgh School Students With Intellectual Disability, Jade Alexis Fulkerson

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

Individuals with intellectual disabilities, with or without autism spectrum disorder, often require structured programming to facilitate acquisition of skills. Video modeling, an evidence-based strategy, offers a promising avenue for skill instruction. While research has demonstrated the effectiveness of human-modeled video interventions, limited research has been conducted into the efficacy of animated models. Addressing this gap, the present study employed an alternating treatments design to compare the effectiveness of human and animated models in teaching exercise behaviors to high school students with intellectual disabilities, with or without autism spectrum disorder. Results revealed variability among participants: one individual exhibited superior performance with …

Comparison Of Video Modeling And In-Vivo Language Instruction In Preschool, Jessah Marlee Hughes

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

Early communication and language development in young children is critically important and those identified as having a language delay, would benefit from intervention. There is a rise in screen time exposure in young children, with some watching variations of popular evidence-based practices (time delay, video modeling, etc.) Most notably, Ms. Rachel is an early childhood learning YouTube sensation. This study seeks to compare the effectiveness and efficiency of video modeling and time delay in the differential use of early sentences during play-based activities.

The Effects Of Hierarchical Training On The Emergence Of Emotion-Related Metaphors In Autistic Children, Katherine Lynch

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

Recently, research on derived relational responding has increased in volume, along with the publication of assessments, curricula, and textbooks on this topic. The allure of engineering derived relations due to purported accelerated learning makes this topic interesting to researchers and practitioners. Recent reviews have examined types of verbal operants, and specific relational frames studied in this body of literature, but there is scarcity in terms of the instructional procedures and variations thereof, and there is little available to focus on single case design (SCD) evaluations of these procedures. Hierarchical training (HT) to produce derived relations between arbitrary stimuli has shown …

Introduction: Cone beam computed tomography (CBCT) is reliable in the assessment of structures related to teeth. The assessment of the inferior alveolar neurovascular (IAN) bundle location using CBCT is considered one of its prime uses in different mandibular surgeries. Methodology: Retrospective CBCT data of patients presented to the institute were assessed to measure relations of IAN. Measurements were taken to assess the bone thickness adjacent to IAN, the superior-inferior dimension between the canal and the teeth, and the dimension between the canal and the inferior border of the mandible. Results: Out of the 170 patients the root apices nearest to …

A Facile Auto-Combustion Pathway For Creating Mn- And Fe-Doped Tio2 Nanostructures And Their Photocatalytic Activity, Gharieb Meselhy

Dentistry

Using a combination of two fuels, an auto-combustion method was used to synthesize pure TiO2 and doped TiO2 with different concentrations of iron(III) (Fe) and manganese(II) (Mn) (1, 3, 5, and 7 mol%). The as-prepared materials were characterized using different techniques, including thermogravimetric analysis (TGA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM), and high-resolution transmission electron microscopy (HR-TEM). The XRD results showed that both pure TiO2 and all doped TiO2 samples had the anatase phase, indicating the crystalline nature of all the as-prepared nanomaterials. Crystal violet decolorization under UV irradiation was used to …

The Impacts Of Gut-Supporting Feed Additives On The Growth Performance, Gut Health, Blood Chemistry, And Immune Status Of Broiler Chickens Exposed To Different Stressors, Richard A. Adefioye

Theses and Dissertations--Animal and Food Sciences

Three experiments were conducted to examine the effects of different feed additives in mitigating stress in broiler chickens. Experiment 1 used 504-day-old male by-product Cobb breeder chicks with 8 treatments replicated 9 times with 7 birds per replicate cage, structured as a 2x4 factorial arrangement of treatments. All birds were on the experimental diets for 20 days. There were 2 levels of lipopolysaccharide (LPS) challenge [no challenge vs. LPS challenge at 1 mg/kg BW) and 4 types of feed additives [no additive, 0.05% PostB, 0.1% PostB, and 0.1% Tynagen^TM]. In experiment 2, 672-day-old male by-product Cobb breeder chicks …

Where Do Central Cushitic Ejectives Come From?, Paul D. Fallon

English & Linguistics Articles

This paper examines and accounts for the origin and presence of ejectives in Central Cushitic (CC) languages. Appleyard (2006) claimed that most occurrences of ejectives are due to borrowing from the Ethiosemitic languages. This is certainly true for all ejectives in Kemantney, and some in Blin and Xamtanga. However, examination of Appleyard’s data shows that only 37% of ejectives in Blin and 25% of ejectives in Xamtanga are found in borrowings. Most ejectives in CC in these two languages are therefore “of indubitable Agaw origin”, which suggests that ejectives are from the proto-language rather than through sound change. This paper …

Liposomes-Encapsulating Double-Stranded Nucleic Acid (Poly I:C) For Head And Neck Cancer Treatment, Vidit Singh, Anna Chernatynskaya, Lin Qi, Hsin Yin Chuang, Tristan Cole, Vimalin Mani Jeyalatha, Lavanya Bhargava, W. Andrew Yeudall, Laszlo Farkas, Hu Yang

Chemical and Biochemical Engineering Faculty Research & Creative Works

Polyriboinosinic acid-polyribocytidylic acid (Poly I:C) serves as a synthetic mimic of viral double-stranded dsRNA, capable of inducing apoptosis in numerous cancer cells. Despite its potential, therapeutic benefits, the application of Poly I:C has been hindered by concerns regarding toxicity, stability, enzymatic degradation, and undue immune stimulation, leading to autoimmune disorders. To address these challenges, encapsulation of antitumor drugs within delivery systems such as cationic liposomes is often employed to enhance their efficacy while minimizing dosages. In this study, we investigated the potential of cationic liposomes to deliver Poly I:C into the Head and Neck 12 (HN12) cell line to induce …

Injectable Dendrimer Hydrogel Delivers Melphalan In Both Conjugated And Free Forms For Retinoblastoma, Remy C. Cooper, Juan Wang, Hu Yang

Chemical and Biochemical Engineering Faculty Research & Creative Works

We report the successful synthesis of an injectable dendrimer hydrogel (DH) carrying melphalan, a clinical drug for retinoblastoma treatment, in both conjugated and free forms. Polyamidoamine (PAMAM) dendrimer generation 5 (G5) is surface-modified with an acid-sensitive acetal-dibenzocyclooctyne linker and then undergoes azide-alkyne cycloaddition with melphalan-PEG-N3 conjugate to form G5-acetal-melphalan. During the DH gelation between G5-acetal-melphalan and PEG-diacrylate, free melphalan is added, resulting in a hydrogel (G5-acetal-melphalan-DH/melphalan) that carries the drug in both conjugated and free forms. Melphalan is slowly released from G5-acetal-melphalan-DH/melphalan, with the conjugated melphalan released more quickly at pH 5.3 due to acid-triggered acetal bond cleavage. The formulation's …

This thesis examines the stories of women, children, and men who suffered from sexual brutality in World War II and how nations try to hide or justify acts of rape and violence. By using as case studies the nations of Japan, Germany, the United States of America, and the Soviet Union, and how they either committed sexual acts of violence or handled rape cases when it came to the …

Saving The World One Scrap At A Time: Identity Labeling As As Tool To Reduce Household Food Waste, Jamiela Bryant

CGU Theses & Dissertations

Food waste is a significant driver of climate change, and it threatens human and planetary health. In fact, the average American household discards between 30% - 40% of their edible food each week. Reducing food waste could divert material from landfills, where it contributes to greenhouse gas emissions. Decreasing food waste would also mean that more of the planet’s resources could contribute to feeding the population. Social psychological research demonstrates the importance of values and identity in understanding and promoting proenvironmental behaviors, such as household food use and disposal. In this dissertation, I review the social psychological literature, focusing on …
