This study examines the impact of university engagement on sense of social fit (SSF), nonspecific psychological distress (NPD), and loneliness among Division I female student-athletes.

Method: A cross-sectional survey was conducted among female student-athletes (n = 111) from eight sports at a mid-sized NCAA Division I university in the Southern U.S. Participants completed validated measures using the SSF scale, UCLA Loneliness scale, and Kessler-6 Psychological Distress scale. An exploratory factor analysis was performed …

Comparison Of Post-Exercise Lipid Oxidation Rates Between Lower And 1 Upper-Body Resistance Training In Well-Trained Females, Alyssa L. Parten

Dissertations

INTRODUCTION: Lipid oxidation (LOx) is a relevant physiological process linked to metabolic health. Despite growing interest in resistance training (RT) as a means to influence substrate utilization LOx responses in females remain poorly characterized, with no study examining whether lower- and upper body RT elicits different LOx patterns during the recovery period following exercise. This distinction may  be relevant because lower-body exercises involves greater fat-free mass (FFM) and energy expenditure,  whereas upper-body exercises recruit less FFM, potentially influencing metabolic effects.

PURPOSE: To  determine if LOx rates after exercise differ between lower- and upper-body RT in well-trained females.

METHODS: Twenty-two females …

Menstrual Cycle Phase Exerts No Influence On Running Economy Parameters In Recreational Female Runners, Savanna K. Knight

Dissertations

Hormonal fluctuations that occur throughout the menstrual cycle (MC) have been shown to affect substrate utilization and oxygen uptake when running. These MC induced changes could manifest as altered running economy (RE) when expressed as energy cost (Ec) and oxygen cost (O2c). Therefore, the current study aimed to determine if RE differs between MC phases, the early follicular phase (E-FP) and the mid-luteal phase (M-LP). Twelve eumenorrheic female recreational runners (ages 25 ± 4y; VO2peak 40.9±4.6 ml/kg/min) completed submaximal RE bouts (60%, 70%, 80% of VO2peak) during the E-FP and M-LP. During each bout, oxygen consumption (VO2), respiratory exchange ratio …

Conserving and recovering the SRKW represents a high-profile transboundary governance challenge that depends heavily on collaboration between a wide range of organizations. To better understand the factors affecting transboundary SRKW governance in the Salish Sea, this study applies a multi-dimensional trust, control, perceived risk framework to assess the inter-organizational architecture supporting collaboration. The analysis is based on key informant interviews (n=32) and surveys (n=35) conducted with policy actors working for different organizations involved …

Cellphone Separation Modulates The Effects Of Working Memory Load On Ex-Gaussian Parameters Of Choice Reaction Time, Michael Gazzanigo, Alexa Quesnel, Catalina Roldan, Xiao Yang

Psychology Faculty Publications

Cognitive effects of cellphone dependency among young adults have garnered increasing research attention. While cellphones have been identified as a distractor in daily tasks, related psychological processes remain unclear. As a potential mechanism underlying those effects of cellphones, excessive working memory (WM) load has not yet been well examined. Our study investigated the effects of the mental representation of cellphone separation on WM. Seventy-five participants (M(age) = 21.3 years; 55 females, 20 males) were assigned into three groups: the cued separation, natural separation, or control group, and completed a block of choice reaction time (CRT) task, and a dual-task block: …

Becoming The Donkey Derby’S ‘Karen’: A Humane Educator’S Autoethnographic Journey Toward Anti-Speciesist Communication, Jesika Keener

Antioch University Dissertations & Theses

Language not only carries oppression as an educative force, but research indicates that language is inherently speciesist and highly pervasive (Ethical Globe, 2021; Guevara Labaca, 2017; Hamlett, 2024; Leach et al., 2023). However, the ontological commitment to speciesism is historically foundational, which makes the total eradication of speciesist communication only viable through an unemerged hypothetical future society (Kahn, 2011). For the possibilities of such a world to come into being, pivotal steps must first be taken to critically engage with the communicated forms of speciesism in order to better understand it and actively resist its reproduction—with the aspiration for this …

Psychological Techniques For Athletes With Orthopedic Musculoskeletal Injuries: A Systematic Review, Nicole L. Williams

Antioch University Dissertations & Theses

Musculoskeletal injuries and recovery from them play a vital role in both the physical and psychological wellbeing of the public. Existing research has been conducted primarily within the athlete population with rehabilitation from these injuries having a profound impact on the physical and mental health. One of the most frequent psychological responses related to sports injuries is a trauma response, which has been shown to hinder the rehabilitation process and to increase the likelihood for reinjury upon return to play. Embedded within the many inputs to trauma responses to these injuries are psychological distress reactions, in particular fear connected to …

We conducted surveys for the Cedar Keys Mole Skink, Plestiodon egregius insularis (Mount), during 1989– 1999 and 2015–2024, examined museum vouchers, and compiled personal observations from others to determine the status and distribution of this subspecies, which has the smallest geographic distribution of the five subspecies and is being considered for federal listing. We observed Cedar Keys Mole Skinks on Airstrip Island, Atsena Otie, Cedar Point, Deer Island, North Key, Scale Key, Seahorse Key, Snake Key, and possibly Dog Island. We have anecdotal reports of Mole Skinks on Way Key, which contains the most potential habitat and is the main …

Environmental And Climate Change Dictionary: Part Ii, Fozia Parveen

Books

When we published our first environment and climate change dictionary in 2023 at IED (https://ecommons.aku.edu/books/117/), I was surprised by the response we received. Many people reached out to us to tell us how they hear these terms in their workplaces and how our dictionary helps them understand the words better. I wanted to make sure that we continue to add words to the dictionary in order to increase the understanding of others but also our own understanding of many terms we hear on a day-to-day basis. This year with the participants of “Introduction to Climate Change” course at FAS we …

Two 2 × 2 factorial experiments were conducted to assess the gene expression profile of systems involved in renal water homeostasis. In Exp. 1, male and female HWE and LWE broilers were individually phenotyped between 4 and 6 wks of age to determine growth performance and water conversion ratio (g water intake/g body weight gain). Kidney samples were obtained from 5 males and 5 females from each line. In Exp. 2, HWE and modern random bred …

Research Note: Increased Lipid Accumulation Within Broiler Preadipocytes During Differentiation In Vitro At Atmospheric Oxygen Tension, Jessica Moraes Cruvinel, Elizabeth S. Greene, Rachel W. Read, Kichoon Lee, Sami Dridi, Paula R. Chen

Poultry Science Faculty Publications and Presentations

In the broiler industry, intensive genetic selection has been placed on muscle growth which has undesirably led to increased fat accretion. Models of chicken preadipocyte differentiation in vitro have conventionally used incubators without the ability to control oxygen (O₂) tension; thus, the cells are exposed to atmospheric (∼20-21%) O₂, which is supraphysiological compared to the O₂ tension within adipose tissue. The objective of this study was to investigate embryonic broiler preadipocyte differentiation at different O₂ tensions, including atmospheric (20%), physiological (5%), and hypoxic (1%). Culture at 1% O₂ resulted in increased …

Resources To Study The Isoforms Of The P53 Family Of Transcription Factors, Dana L. Woodstock

Electronic Theses & Dissertations (2024 - present)

The p53 family of transcription factors regulates diverse gene regulatory networks such as those involved in DNA damage repair, epidermal commitment, and neuronal development. As a result, dysfunction in these pathways lead to numerous human health conditions, including multiple types of cancer and craniofacial developmental disorders. Each family member regulates a distinct gene network leading to varied cellular and organismal phenotypes, but all are capable of regulating programmed cell death, likely due to considerable similarity between protein structure and binding sites in DNA. Analysis of these shared and distinct functions is complicated by each p53 family member gene (TP53, TP63, …

Characterization Of Adaptive Quorum Sensing In Pseudomonas Aeruginosa, Kayla Simanek

Electronic Theses & Dissertations (2024 - present)

Pseudomonas aeruginosa is an opportunistic pathogen that is highly antibiotic resistant and causes tens of thousands of infections each year. It persists in hospitals by forming biofilms on medical equipment like ventilators and catheters, making it difficult to eradicate. Biofilm formation, among other virulence factors of P. aeruginosa, is regulated through quorum sensing, a mechanism of bacterial communication. Quorum sensing is primarily coordinated through LuxI-R type systems comprised of an autoinducer synthase and receptor, respectively. Canonically, the first system to be expressed is LasI-R, and LasR upregulates the second arm of the quorum sensing network, the RhlI-R system. Research …

Physiological Structure, Activity, And Interactions Of The Formin, Human Diaphanous Homologue 1, Aaron Premo

Electronic Theses & Dissertations (2024 - present)

Human Diaphanous Homologue 1 (DIAPH1) is a 143 kDa functional protein that plays a critical role in the regulation of actin dynamics within eukaryotic cells.

Beyond its structural role in actin polymerization, DIAPH1 is implicated in several diseases, including diabetes, cancer, and inflammation, as well as complications like hearing loss. Despite its significance in human health, the functional and structural properties of DIAPH1, particularly in human cells, remain less explored compared to related proteins, …

Transcriptome-Wide Gene Expression Analysis Of Skeletal Muscles Of Duchenne Muscular Dystrophy Mouse Models And Patients, Olivia N. Ransiear

Electronic Theses & Dissertations (2024 - present)

Duchenne Muscular Dystrophy (DMD) is an X-linked recessive muscle degenerative disease that frequently proves fatal by age 30. It primarily affects adolescent males with symptoms appearing as early as age 6. Patients quickly lose their ability to walk due to muscle weakness and are confined to wheelchairs for the remainder of their lives. DMD is caused by a mutation in the dystrophin gene. Without dystrophin, mechanical stress, injury, or shock takes a drastic toll on muscle tissue and muscle stem cells, rendering them unable to regenerate or be repaired. This results in a rapid loss of muscular strength and muscle …

Hippocampal Insulin Exists! In Vivo Sampling Methods, Basal Concentrations, Recurrent Hypoglycemia, And Behavioral Extracellular Insulin Responses, Starlette R. Douglass

Electronic Theses & Dissertations (2024 - present)

Insulin has widespread actions within the brain, including energy homeostasis, modulation of feeding, and as a key component of memory processes. Further, brain insulin dysfunction correlates with Alzheimer's disease and other neurodegenerative disorders. To this point, measurement of hippocampal insulin has been limited. Determining in vivo hippocampal insulin levels both at a healthy baseline and after, e.g., induction of a disease state or in response to cognitive challenge, is essential to advance our understanding of both insulin's procognitive actions and to guide potential therapeutic interventions.

We first sought to establish a sampling technique for insulin within awake and moving rats …

Adaptive Evolution Shapes The Transmissibility Of West Nile Virus In New York State, Sean M. Bialosuknia

Electronic Theses & Dissertations (2024 - present)

Arthropod-borne viruses (arboviruses), which are maintained in nature in complex transmission cycles involving hematophagic invertebrates and their vertebrate hosts, are the cause of a significant and expanding global health burden. Defining arbovirus-host interactions is necessary if we are to understand the adaptive and epidemiological potential of arboviruses. The results presented with West Nile virus (WNV Flaviviridae: Orthoflavivirus), are a compilation of such studies. WNV is the most prevalent arboviral pathogen in the U.S. and the most geographically distributed arbovirus in the world. Despite the evolutionary potential of these RNA viruses, WNV and other arboviruses have experienced only limited …

Heterogeneous Being: The Inhumanities And The Creative-Scientific Aesthetic, Steven L. Ogden

Electronic Theses & Dissertations (2024 - present)

Heterogeneous Being attempts to set the often-disunited aspects of the sciences and humanities in congruence and to extol and advance a hybrid creative-scientific aesthetic that moves beyond any restricted dimensions of its previously segregated fields of study. It likewise expresses the need to perpetuate that hybrid form of inquiry and representation to successfully address or convey the precarious realities of Earth’s ecological and environmental conditions. Heterogeneous Being asks readers to observe the inexhaustible proofs of our pluralized configurations with the nonhuman world, to recognize the agentic potentialities nonhuman subjects may hold both in and outside of those inhuman enmeshments, and …

The Role Of The Nasal Migratory Mass In Olfactory Bulb Formation And Fertility, Charisse Martin

Electronic Theses & Dissertations (2024 - present)

The olfactory migratory mass plays an essential role in the development of the olfactory bulb by facilitating the migration of the gonadotropin-releasing hormone neurons from the olfactory placode to the pre-optic hypothalamic area in the brain. In mammals, the migration of GnRH neurons is critical for establishing the hypothalamic-pituitary-gonadal axis (HPG axis), which regulates reproductive function through the production and secretion of gonadotropins. Luteinizing hormone (LH) and Follicle-stimulating hormone (FSH) instruct the gonads to function appropriately, ensuring sexual maturation and fertility. Disruptions in this migratory pathway have been linked with Kallmann syndrome, a condition characterized by low levels of GnRH, …

Nat10 Stabilizes Immune Response Factors Aiding With Cellular Immune Response To Zika Virus Infection, Shawn Gianola

Electronic Theses & Dissertations (2024 - present)

Zika virus (ZIKV) remains a significant public health concern due to major gaps in our understanding of its infection mechanisms and immune evasion strategies. Despite its link to severe complications such as microcephaly and Guillain-Barré Syndrome (GBS), no vaccine or targeted antiviral therapies exist. Compounding this concern is the expanding habitat of ZIKV-carrying mosquito vectors, driven by climate change, which increases the risk of future outbreaks in previously unaffected regions.

One promising area of investigation involves post-transcriptional modifications (PTMs) chemical alterations to RNA that influence its stability, translation, and function. Although over 170 PTMs have been identified, their roles remain …

Identification Of Fentanyl And Fentanyl Analogs Found In Human Urine Using Gas Chromatography-Mass Spectrometry, Adam M. Fisher

Electronic Theses & Dissertations (2024 - present)

Identification of fentanyl and its analogs in unknown samples is a frequent practice completed in forensic crime labs, as the fentanyl epidemic continues. With the continued increase in illicit drug use, crime labs are not able to keep up with the flooding of new fentanyl analogs being developed, resulting in new analogs slipping past the crime labs’ authority. This research is to start to develop a database of commonly found fentanyl analogs in New York State. Gas Chromatography-Mass Spectrometry (GC-MS) is a widely used method for the detection and identification of illicit drugs in forensic crime labs. A database that …

Sulfur Chemistry For Protein Synthesis And Modification: From Thiolactone To Bicyclic Sulfoxide Frameworks, Yuming Wen

Electronic Theses & Dissertations (2024 - present)

This dissertation explores two intersecting themes in modern chemical biology: (1) the design of novel ligands for transition-metal catalysis, and (2) the development of thiolactone-mediated strategies for protein synthesis and modification in aqueous media. Together, these studies advance chemical methods for precise molecular transformations under mild, biocompatible conditions.

In the first chapter, a geometrically constrained bicyclic [3.3.1] sulfoxide framework was developed as a new class of bissulfoxide ligands for palladium-catalyzed C–H functionalization. The ligand was synthesized concisely from thiophenol through a three-step sequence and shown to promote allylic C–H amination and alkylation reactions with high efficiency. The catalytic system tolerated …

Biological Sciences: Faculty Publications

Zoonoses are infectious diseases transmitted from animals to humans. Bats have been suggested to harbour more zoonotic viruses than any other mammalian order1. Infections in bats are largely asymptomatic2,3, indicating limited tissue-damaging inflammation and immunopathology. To investigate the genomic basis of disease resistance, the Bat1K project generated reference-quality genomes of ten bat species, including potential viral reservoirs. Here we describe a systematic analysis covering 115 mammalian genomes that revealed that signatures of selection in immune genes are more prevalent in bats than in other mammalian orders. We found an excess of immune gene adaptations in the ancestral chiropteran branch and …

Organic Carbon Decay Mediated By A Mesopelagic Microbial Community: The Relevance Of Carbon Pools And Broad Biochemical Composition, Noah J. Craft, Alexander B. Bochdansky

OES Faculty Publications

The mesopelagic zone is a site of strong microbially driven particle attenuation with depth and thus plays a crucial role in controlling the transfer efficiency of the ocean's biological pump. However, little quantitative information exists on the dependency of decay processes on the source material. Here we followed the decay of ¹⁴C-labeled dead particulate organic carbon (POC) and dissolved organic carbon (DOC) from three different phytoplankton species, and two incubations of live diatoms, in mesopelagic water over 3 months. Commonly used first-order kinetics failed to adequately describe the decay of organic material as rate constants varied from day to day. …
