A Republic Of Pawprints: The Rise And Reign Of The Alaskan Sled Dog, 1870-1970, Christopher David Adkins

USF Tampa Graduate Theses and Dissertations

This dissertation charts the career of the Alaskan sled dog: how it was used as an engine of development, how it became a symbol for early American Alaska, and how it fell victim to obsolescence as newer and faster means of conveyance became available. The figure of the sled dog in the Arctic is complex. Because it was closer to the wolf in phenotype both it, and Alaska, were buffeted by the same White settler expectations and Darwinian chauvinism which afflicted its Indigenous peoples. This would intensify during the baptisms by fire of the gold rushes. Dog abuse – overwork, …

Addressing Mental Health Challenges In Graduate Education, Obed A. Boateng

Masters Projects

Graduate students face a multitude of stressors that can negatively impact their mental health and wellbeing, including academic pressures, work-life balance issues, and financial strains. However, minimal attention has been focused the needs of graduate student population, and existing support are limited. More so, student affairs professionals and practitioners (SAPPs) often engage and interact with graduate student. Yet, many SAPPs who are interested in helping address graduate students’ mental health needs lack sufficient training to effectively support graduate students experiencing mental health challenges. The purpose of this project is to develop and implement a comprehensive training program to equip SAPPs …

Vhl Governs M6a Modification And Pik3r3 Mrna Stability In Clear Cell Renal Cell Carcinomas, Hyemin Lee, Li Zhuang, Boyi Gan

Faculty, Staff and Student Publications

N6-Methyladenosine (m6A), a prevalent posttranscriptional modification, plays an important role in cancer progression. Clear cell renal cell carcinoma (ccRCC) is chiefly associated with the loss of the von Hippel-Lindau (VHL) gene, encoding a component of the E3 ubiquitin ligase complex. In this issue of the JCI, Zhang and colleagues unveiled a function of VHL beyond its canonical role as an E3 ubiquitin ligase in regulating hypoxia-inducible factors (HIFs). It also governed m6A modification by orchestrating the assembly of m6A writer proteins METTL3 and METTL14, thereby stabilizing PIK3R3 mRNA. Mechanistically, PIK3R3 contributed to p85 ubiquitination, which restrained PI3K/AKT signaling and consequently …

Vitamin A Status Modulates Epithelial Mesenchymal Transition In The Lung: The Role Of Furin, M Teresa Cabezuelo, Luis Torres, Elena Ortiz-Zapater, Gerardo López-Rodas, M Pilar Marín, Joaquín Timoneda, Juan R Viña, Rosa Zaragozá, Teresa Barber

Faculty, Staff and Student Publications

Vitamin A deficiency (VAD) induced TGF-β hyperactivation and reduced expression of cell adhesion proteins in the lung, suggesting that the disruption of retinoic acid (RA) signaling leads to epithelial-mesenchymal transition (EMT). To elucidate the role of lung vitamin A status in EMT, several EMT markers and the expression of the proprotein convertase furin, which activates TGF-β, were analyzed in two experimental models. Our in vivo model included control rats, VAD rats, and both control rats and VAD rats, treated with RA. For the in vitro studies, human bronchoalveolar epithelial cells treated with RA were used. Our data show that EMT …

Identifying Covariate-Related Subnetworks For Whole-Brain Connectome Analysis, Shuo Chen, Yuan Zhang, Qiong Wu, Chuan Bi, Peter Kochunov, L Elliot Hong

Faculty, Staff and Student Publications

Whole-brain connectome data characterize the connections among distributed neural populations as a set of edges in a large network, and neuroscience research aims to systematically investigate associations between brain connectome and clinical or experimental conditions as covariates. A covariate is often related to a number of edges connecting multiple brain areas in an organized structure. However, in practice, neither the covariate-related edges nor the structure is known. Therefore, the understanding of underlying neural mechanisms relies on statistical methods that are capable of simultaneously identifying covariate-related connections and recognizing their network topological structures. The task can be challenging because of false-positive …

Hammerhead-Type Fxr Agonists Induce An Enhancer Rna Fincor That Ameliorates Nonalcoholic Steatohepatitis In Mice, Jinjing Chen, Ruoyu Wang, Feng Xiong, Hao Sun, Byron Kemper, Wenbo Li, Jongsook Kemper

Faculty, Staff and Student Publications

The nuclear receptor, farnesoid X receptor (FXR/NR1H4), is increasingly recognized as a promising drug target for metabolic diseases, including nonalcoholic steatohepatitis (NASH). Protein-coding genes regulated by FXR are well known, but whether FXR also acts through regulation of long non-coding RNAs (lncRNAs), which vastly outnumber protein-coding genes, remains unknown. Utilizing RNA-seq and global run-on sequencing (GRO-seq) analyses in mouse liver, we found that FXR activation affects the expression of many RNA transcripts from chromatin regions bearing enhancer features. Among these we discovered a previously unannotated liver-enriched enhancer-derived lncRNA (eRNA), termed FXR-induced non-coding RNA (

Beardsley, Wei-Liang Chen, Lisa Conant, Marsha Malloy, Joseph Heffernan, Brendan Quirk, Robert W. Prost, Mohit Maheshwari, Jeffrey Sugar, Harry T. Whelan

Biomedical Engineering Faculty Research and Publications

Functional near infrared spectroscopy (fNIRS) and functional magnetic resonance imaging (fMRI) both measure the hemodynamic response, and so both imaging modalities are expected to have a strong correspondence in regions of cortex adjacent to the scalp. To assess whether fNIRS can be used clinically in a manner similar to fMRI, 22 healthy adult participants underwent same-day fMRI and whole-head fNIRS testing while they performed separate motor (finger tapping) and visual (flashing checkerboard) tasks. Analyses were conducted within and across subjects for each imaging approach, and regions of significant task-related activity were compared on the cortical surface. The spatial correspondence between …

Islamophobia In Public Schools: A Mixed Methods Look At The Effectiveness Of Parental Ethnic-Racial Strategies In Promoting Resilience Among Muslim Children, Lallia Allali

Dissertations

The ongoing Islamophobic ideology in the United States has magnified discriminatory practices, exclusion, and increased violence toward Muslims (Esposito & Kalin, 2011; Trudo, 2021), and Islamophobia has further disadvantaged Muslim American adolescents through various forms of discrimination against them in schools. In fact, Muslim American students report the highest rate of discrimination across all religious groups, and researchers have found that active family ethnic-racial socialization can often mitigate the negative impacts of discrimination (Hughes et al., 2006; Hughly et al., 2019).

To test this hypothesis, this study was designed to focus on Muslim families’ ethnic-racial socialization practices and the implications …

School of Biological and Marine Sciences

Uncontrolled fires place considerable burdens on forest ecosystems, compromising our ability to meet conservation and restoration goals. A poor understanding of the impacts of fire on ecosystems and their biodiversity exacerbates this challenge, particularly in tropical regions where few studies have applied consistent analytical techniques to examine a broad range of ecological impacts over multiyear time frames. We compiled 16 y of data on ecosystem properties (17 variables) and biodiversity (21 variables) from a tropical peatland in Indonesia to assess fire impacts and infer the potential for recovery. Burned forest experienced altered structural and microclimatic conditions, resulting in a proliferation …

Scaling Of Buccal Mass Growth And Muscle Activation Determine The Duration Of Feeding Behaviours In The Marine Mollusc Aplysia Californica, Jeffery P. Gill, Anna Skalski De Campos, Katherine X. Wang, Isha V. Kaza, Victoria X. Fan, Hillel J. Chiel

Faculty Scholarship

The mechanical forces experienced during movement and the time constants of muscle activation are important determinants of the durations of behaviours, which may both be affected by size-dependent scaling. The mechanics of slow movements in small animals are dominated by elastic forces and are thus quasistatic (i.e. always near mechanical equilibrium). Muscular forces producing movement and elastic forces resisting movement should scale identically (proportional to mass^2/3), leaving the scaling of the time constant of muscle activation to play a critical role in determining behavioural duration. We tested this hypothesis by measuring the duration of feeding behaviours in the …

Low adherence to self-guided digital mental health interventions (DMHIs) have raised concerns about their real-world effectiveness. Naturalistic data from self-guided DMHIs are often not available, hindering our ability to assess adherence among real-world users. This study aimed to analyze 3 years of user data from the public launch of an empirically supported 12-session self-guided DMHI, to assess overall program adherence rates and explore predictors of adherence. Data from 984 registered users were analyzed. Results showed that only 14.8% of users completed all 12 modules and 68.6% completed less than half of the modules. Users who were younger, had milder depression, …

Retrospective Consecutive Controlled Case Series Of Outcomes For Functional Analyses Of Severe Destructive Behavior, Jessie K. Weber, Katherine R. Brown, Billie J. Retzlaff, Alyssa M. Hurd, Heather J. Anderson, Kendra Smallwood

Psychology Faculty Publications

Functional analysis methods allow clinicians to determine the variable(s) that maintain destructive behavior. Previous reviews of functional analysis outcomes have included large samples of published and unpublished datasets (i.e., clinical samples). The purpose of this review was to conduct a large retrospective consecutive controlled case series of clinical functional analyses. We sought to identify the prevalence of differentiation, procedural modifications for undifferentiated and differentiated cases, and identified function(s) of destructive behavior. In addition, we extended the existing literature by determining whether functional analysis differentiation and function varied when single or multiple behavior topographies were consequated in the functional analysis. We …

This change can lead to feelings of discomfort or nervousness when the subject is brought up. A parent workshop geared towards helping parents better understand the way math content is being taught can help them to feel more comfortable with math and more prepared to help their children. To help combat this issue, …

Relationship Between Knowledge, Years Of Licensure, And Attitudes Of Midwives About Female Genital Mutilation And Its Prevalence Among Their Patients In Bawku, Ghana, Frank Debrah

Walden Dissertations and Doctoral Studies

Female genital mutilation (FGM) is one of the hindrances to girls' development. FGM is often a rite of passage between childhood and adulthood. This cross-sectional study examined the relationship between the knowledge, years of licensure, and attitudes of midwives regarding FGM and the prevalence of FGM among their patients in Bawku, Ghana. Bronfenbrenner's social ecological model served as the theoretical framework to describe the link between midwives' knowledge, attitude, years of licensure, and FGM prevalence. The knowledge and attitude of midwives were classified as exosystem factors. Hence, their direct interaction with patients is likely to affect the patient's practice of …

Grazing On The Arizona Strip: Catchment History And Repair, Melanie Heaton

All Current Publications

Water, not forage, is the limiting factor for wildlife and livestock grazing the Arizona Strip, a nearly 3-million-acre piece of land located north of the Grand Canyon and south of the Utah border. Since springs and groundwater are rare or absent, harvesting of natural precipitation is the main source of water for animals. Catchment systems, which capture precipitation on a sloped rubber apron and contain it in a large tank or lined pond, are used by government agencies and grazing permittees to efficiently provide water for wildlife and livestock. As catchments reach the end of their useful lives, tank replacement …

Clinical Implications Of Inaccurate Potassium Determination In Hemolyzed Pediatric Blood Specimens, Dennis J Dietzen, Ronald Jackups, Mark A Zaydman

2020-Current year OA Pubs

BACKGROUND: Analysis of whole blood specimens is rapid and saves blood, but hemolysis may go undetected and compromise the accuracy of potassium measurement. We aimed to define the frequency and magnitude of error in whole blood potassium measurement.

METHODS: 34 months of whole blood and plasma potassium data were extracted from patients aged less than 2 years at the time of sample acquisition. Hemolysis was detected using the plasma "H index." The magnitude of potassium bias was estimated from the difference between paired whole blood and plasma measurement separated by less than 2 h.

RESULTS: 56,000 of the 105,000 data …
