Connecting A Community Through A Family Literacy Project And Virtual Writing Collaboration: University Students Facilitate Access To Literature During The Pandemic, Anne Katz Ph.D., Alexandria Sledge-Tollerson B.A. In Early Childhood Education

Georgia Journal of Literacy

The importance of accessing and sharing children’s literature took on new meaning as educators pivoted to remote and online learning models over the course of the past school year. In light of the pandemic, College of Education pre-service educators enrolled in a Fall 2020 Language and Literacy Development course (which is usually scheduled to meet face-to-face twice a week) was re-structured as hybrid, where a group of students were scheduled to meet partially face-to-face and partially online on a weekly basis. I planned to adapt my family literacy project collaboration with a local community center, an academic service learning assignment …

Culturally Relevant Teaching For The 21st Century: The Success And Challenges Of Pre-Service Teachers When Using Technology In Critical Ways, Virginie Jackson, Stacy Delacruz, Dominique Harry

Georgia Journal of Literacy

This case study examined pre-service teachers' use of technology as they implemented culturally relevant literacy lessons while tutoring elementary students in their field placement sites. As we enter a new decade, we want our students to be future-ready with technology skills. Here, we present an examination of how pre-service teachers integrated culturally relevant teaching with technology along with a discussion of the tools and devices their students used. Findings provided evidence that as pre-service teachers experienced authentic and engaging learning experiences within a supportive space, they emerged equipped to teach in culturally responsive ways that supported student learning and deeper …

Predicting Lifespan Of Drosophila Melanogaster: A Novel Application Of Convolutional Neural Networks And Zero-Inflated Autoregressive Conditional Poisson Model, Yi Zhang, V. A. Samaranayake, Gayla R. Olbricht, Matthew S. Thimgan

Mathematics and Statistics Faculty Research & Creative Works

A model to classify the lifespan of Drosophila, the fruit fly, into short- and long-lived categories based on a sleep characteristic, extracted from activity data, is developed using a two-stage process. Stage 1 models the per-minute activity counts of each fly using a zero-inflated autoregressive conditional Poisson model. These probabilities are allowed to vary hourly, reflecting the circadian and other cycles present in a fly's sleep architecture. A 5-day moving window is used to model data allowing the model parameters to vary over the course of the fly's life. The resulting probabilities capture information about changes in sleep patterns with …

Microrrelatos (Flash Fiction) Collection

Amanece. Cada día pasa, no lo he visto fallar: El sol brilla tan fuerte y nos da luz. Somos mucho aquí en este desierto, y todos estamos hartos de sus rayos. Los coyotes y pumas duermen, Y los roedores y reptiles se esconden. Pero nosotros no tenemos esa opción, nos quedamos en el sol todo el día. Pero por alguna razón, me gusta. Y después de un día muy largo y caloroso atardece.

Probiotic Intervention Improves Recovery Of Hippocampal Memory And Hippocampal Atrophy Following Disruption From High-Fat Diet In Adult Rats, Sanyourah A. El-Hulu

Honors Scholars Collaborative Projects

Presently, lifestyle factors such as chronic high-fat diet (HFD) consumption occurs concomitantly with weight gain and obesity (Gil-Cardoso et al., 2017; Stranahan et al., 2008). In turn, obesity has been associated with impairments to mental functioning, specifically to memory. Human epidemiological studies show that HFD intake containing saturated, and omega-6-fatty acids is associated with worse performance on a cognitive task whereas a lower fat diet containing omega-3-fatty acids is associated with a protective effect against cognitive decline (Zhang et al., 2006; Uranga et al., 2010). One explanation for this is the critical role of the gut bacteria in brain health. …

Evaluation Of Essential Oil Products On Performance, Intestinal Permeability, Bone Mineralization, And Oxidative Stress Parameters On Broiler Chickens Under Heat Stress Conditions, Jared Ruff

Poultry Science Undergraduate Honors Theses

The goal of this study was to show how dietary supplementation of three different formulations of essential oils (EO) affected the performance of broiler chickens during heat stress (HS). Day-of-hatch Cobb 500 chicks (n = 500) were randomly divided into four groups: 1. HS control + control diets; 2. HS + control meals supplemented with 37 ppm EO of Lippia origanoides (LO); 3. HS + control diets supplemented with 45 ppm LO + 45 ppm EO of Rosmarinus officinalis (RO) + 300 ppm red beetroot; 4. HS + 45 ppm LO + 45 ppm RO + 300 ppm natural betaine. …

Differentiating The Mechanistic Role And Chemotherapeutic Potential Of Src And Podoplanin In Oncogenic Transformation, Edward P. Retzbach

Graduate School of Biomedical Sciences Theses and Dissertations

There were an estimated 20 million new cancer cases worldwide in 2020, resulting in nearly 1000 deaths per hour [1]. Oral cancer exemplifies the difficulties of treating cancer patients. The first line for oral cancer treatment is surgery and radiation that can lead to patient disfigurement and decreased quality of life in cancer survivors [2-4]. Though there have been many developments in chemotherapy in the last 30 years, the 50% mortality rate associated with oral cancer has not changed [4, 5]. Longitudinal studies that track survival rates in oral cancer patients demonstrate a 3-fold reduction in patient deaths when patients …

Gregarine Single-Cell Transcriptomics Reveals Differential Mitochondrial Remodeling And Adaptation In Apicomplexans, Eric D. Salomaki, Kristina X. Terpis, Sonja Rueckert, Michael Kotyk, Zuzana Kotyková Varadínová, Ivan Čepička, Christopher E. Lane, Martin Kolisko

Biological Sciences Faculty Publications

Background: Apicomplexa is a diverse phylum comprising unicellular endobiotic animal parasites and contains some of the most well-studied microbial eukaryotes including the devastating human pathogens Plasmodium falciparum and Cryptosporidium hominis. In contrast, data on the invertebrate-infecting gregarines remains sparse and their evolutionary relationship to other apicomplexans remains obscure. Most apicomplexans retain a highly modified plastid, while their mitochondria remain metabolically conserved. Cryptosporidium spp. inhabit an anaerobic host-gut environment and represent the known exception, having completely lost their plastid while retaining an extremely reduced mitochondrion that has lost its genome. Recent advances in single-cell sequencing have enabled the first broad genome-scale …

Going Berserk, Running Amok, And The Extraordinary Capabilities And Invulnerability Of Battle Trance, Jenny Wade

International Journal of Transpersonal Studies

Battle trance, which evolved from instinctive defensive and offensive behaviors for close combat, involves socially transgressive processes like becoming-intense and becoming-animal that produce non-ordinary psychophysical states useful in fighting. Berserkergang (going berserk) is one of the best attested types of battle trance and the latest in a long history of Indo-European ecstatic warrior cults, but the state has been identified cross-culturally in consecrated holy amok warriors and in juramentado. Colonial interpretations for centuries have tended to denigrate such fighting styles, even though they involve discipline, spiritual dedication, and altruistic self-sacrifice, especially by falsely attributing such states to intoxication or insanity. …

Going Vegan Or Vegetarian: Motivations & Influences, Faunalytics, Jo Anderson, Marina Milyavskaya

Diet

After studying hundreds of U.S. and Canadian consumers during their transition to vegetarianism or veganism (collectively referred to as veg*nism), a new report from research organization Faunalytics found that 42% of people’s veg*n journeys were motivated by health, 20% by animal protection, and 18% by environmental concern. For animal advocates interested in helping new vegans and vegetarians maintain their change of lifestyle, study results suggest a focus on self-driven motivations (like personal values or moral identity) and experiences with animal advocacy.

Acetone Ingestion Mimics A Fasting State To Improve Glucose Tolerance In A Mouse Model Of Gestational Hyperglycemia, Sandra Szlapinski, Brenda Strutt, Madeline Deane, Edith Arany, Jamie Bennett, David J. Hill

Paediatrics Publications

Gestational diabetes mellitus results, in part, from a sub‐optimal β‐cell mass (BCM) during pregnancy. Artemisinins were reported to increase BCM in models of diabetes by α‐ to β‐cell conversion leading to enhanced glucose tolerance. We used a mouse model of gestational glucose intolerance to compare the effects of an artemisinin (artesunate) on glycemia of pregnant mice with vehicle treatment (acetone) or no treatment. Animals were treated daily from gestational days (GD) 0.5 to 6.5. An intraperitoneal glucose tolerance test was performed prior to euthanasia at GD18.5 or post‐partum. Glucose tolerance was significantly improved in both pregnant and non‐pregnant mice with …

Paediatrics Publications

Purpose of the Review: Conditions typically prevalent in adults such as hypertension, kidney stones, osteoporosis, and chronic kidney disease are increasing among adolescents and young adults (AYA). The purpose of this review is to describe the association of these conditions to a high salt diet among pediatric patients. Recent Findings: We present animal, human, and 23Na MRI evidence associated with the negative impact of high dietary salt in children. Special focus is placed on novel 23Na MRI imaging which reveals the important concept of a third compartment for sodium storage in soft tissue. Finally, we make recommendations on who should …

Ectopic Mineralisation Of The Mandibular Symphysis In Ent1 Knockout Mice: A Model Of Dystrophic Calcification, Dale E. Fournier, Kim L. Beaucage, Ryan J. Beach, Patti K. Kiser, Cheryle A. Séguin, S. Jeffrey Dixon

Paediatrics Publications

Equilibrative nucleoside transporter 1 (ENT1) transfers nucleosides, such as adenosine, across plasma membranes. We reported previously that mice lacking ENT1 (ENT1−/−) exhibit progressive ectopic calcification of spinal tissues—a phenotype resembling diffuse idiopathic skeletal hyperostosis (DISH) in humans. Our objective was to investigate potential calcification of orofacial tissues in ENT1−/− mice. Heads of wild-type mice and ENT1−/− mice from 3 to 17 months were evaluated using microcomputed tomography (μCT). Some heads were decalcified and processed for histological assessment. Other heads were examined using energy dispersive X-ray spectroscopy and micro X-ray diffraction. Using μCT, ENT1−/− mice showed extensive radiopaque lesions within the …

Diet-Induced Obesity Leads To Behavioral Indicators Of Pain Preceding Structural Joint Damage In Wild-Type Mice, Geoffrey J. Kerr, Bethia To, Ian White, Magali Millecamps, Frank Beier, Matthew W. Grol, Laura S. Stone, Cheryle A. Séguin

Bone and Joint Institute

Introduction: Obesity is one of the largest modifiable risk factors for the development of musculoskeletal diseases, including intervertebral disc (IVD) degeneration and back pain. Despite the clinical association, no studies have directly assessed whether diet-induced obesity accelerates IVD degeneration, back pain, or investigated the biological mediators underlying this association. In this study, we examine the effects of chronic consumption of a high-fat or high-fat/high-sugar (western) diet on the IVD, knee joint, and pain-associated outcomes. Methods: Male C57BL/6N mice were randomized into one of three diet groups (chow control; high-fat; high-fat, high-sugar western diet) at 10 weeks of age and remained …

Sound Level Context Modulates Neural Activity In The Human Brainstem, Björn Herrmann, Sonia Yasmin, Kurdo Araz, David W. Purcell, Ingrid S. Johnsrude

Brain and Mind Institute Researchers' Publications

Optimal perception requires adaptation to sounds in the environment. Adaptation involves representing the acoustic stimulation history in neural response patterns, for example, by altering response magnitude or latency as sound-level context changes. Neurons in the auditory brainstem of rodents are sensitive to acoustic stimulation history and sound-level context (often referred to as sensitivity to stimulus statistics), but the degree to which the human brainstem exhibits such neural adaptation is unclear. In six electroencephalography experiments with over 125 participants, we demonstrate that the response latency of the human brainstem is sensitive to the history of acoustic stimulation over a few tens …

Efficacy And Safety Of Low-Dose Versus High-Dose Hydrocortisone To Treat Hypotension In Neonates: A Protocol For A Systematic Review And Meta-Analysis, Katelyn Sushko, Nada Al-Rawahi, Kristi L. Watterberg, John Van Den Anker, Catherine Litalien, Jacques Lacroix, Abdul Razak, Samira Samiee-Zafarghandy

Pediatrics Research and Scholarship

BACKGROUND: Impaired adrenal function is a well-described entity in critically ill term and preterm neonates with systemic hypotension. The standard treatment for neonatal hypotension includes volume expanders and vasopressors. Recent evidence supports the use of glucocorticoids for the primary or rescue treatment of neonatal hypotension associated with impaired adrenal function. However, inconsistency regarding the prescribed dosing regimen to provide the best balance between efficacy and safety in this vulnerable population remains an area of concern.

METHODS: We will conduct a systematic review and meta-analysis to evaluate low-dosing compared with high-dosing regimens of hydrocortisone for the treatment of hypotension in critically …

Effects Of Creatine Supplementation Protocols And Doxorubicin On Cardiac And Skeletal Muscle Phosphocreatine System, Salaheddin M. A. Sharif

Dissertations

Doxorubicin (Dox) is a highly effective anticancer drug used to treat several cancer types; however, its use is limited due to its cytotoxicity (cardiotoxicity and myotoxicity). Doxorubicin-induced cardiotoxicity might occur within days and lead to congestive heart failure. Doxorubicin-induced myotoxicity involves fatigue, cachexia, and skeletal muscle dysfunction. Although the exact mechanisms causing Dox-induced cytotoxicity are not entirely understood, an alteration in the phosphocreatine system seems to be a central mechanism where studies showed Dox decreased phosphocreatine (PCr), creatine (Cr), impaired creatine kinase (CK) enzyme function, and decreased creatine transporter (CrT) expression in cultured cardiomyocytes. Ultimately, Dox-induced cytotoxicity might compromise quality …

Moving Across Rural Spaces: A Content Analysis Of Contemporary Realistic Fiction Picturebooks With Rural Settings, Suzette Youngs, James A. Erekson, Christine Kyser

Reading Horizons: A Journal of Literacy and Language Arts

Romanticized rural storytelling creates difficulties for rural children in finding mirrors, seeing people like themselves and places like their homes as principal characters and settings in picturebooks. The same romanticism likewise makes it unlikely for picturebook readers in cities and suburbs to find realistic windows into rural life. Despite children’s book publishers’ purposeful increases in realistic representations of children across racial and cultural groups in recent decades, realistic and diverse narratives within rural spaces remain underrepresented, if not invisible. Drawing on critical rural theory (Fulkerson & Thomas, 2014; Williams, 1973) and tenets of nostalgia and the rural idyll (Boym, 2001, …

Towards A More Comprehensive Understanding Of Wild Pig (Sus Scrofa) Impacts On Agricultural Producers: Insights From A Texas Case Study, Keith M. Carlisle, Nicole Didero, Sophie Mckee, Julie Elser, Stephanie A. Shwiff

United States Department of Agriculture Wildlife Services: Staff Publications

This research investigates the impacts of invasive wild pigs (Sus scrofa Linneaus) on agricultural producers in Texas, with the aim of identifying and describing all categories of wild pig impacts and quantifying the extent of producers’ over- or underestimation of their total wild pig-related costs in 2018, as compared to calculations based upon data subsequently provided by the producers about individual wild pig-related costs and losses. Based on interviews with 23 producers in 16 Texas counties, we identified more than 20 discrete categories of negative impacts and negligible positive impacts associated with wild pigs. Among them were categories that have …

Studies Of Avian Nasal Mites (Acari: Rhinonyssidae And Ereynetidae) And Their Interaction With The Brood Parasite Brown-Headed Cowbird (Molothrus Ater: Icteridae) And Phylogenetic Inferences Of The Genus Ptilonyssus (Rhinonyssidae) On Different Passerine Hosts Associated To Three States In The Us, Alexis D. Hilario Perez

Graduate Theses and Dissertations

Nasal mites are endoparasites that spend their entire life cycle inside the nasal cavities and respiratory passages of birds. The Brown-Headed cowbird (Molothrus ater) (BHCO) is an icterid bird that uses brood parasitism as a reproductive strategy in which it lays an egg in the nest of a different bird species and allows the host to raise its young. Interestingly, nasal mites reported from cowbirds represent the same species found infesting other icterids and other common host groups. In the first study, I examined how diversity and host prevalence might change in a large sample size of BHCO associated with …

Examining Risks To Honey Bee Pollinators Foraging In Agricultural Landscapes, Jon Zawislak

Graduate Theses and Dissertations

Bee pollinators provide essential ecological services to wild plant communities, and addtremendous economic value to agriculture by improving both the quality and quantity of crop yield. Beekeepers are often contracted by growers to provide colonies of honey bees for pollination of high-value produce (fruits, vegetables and nuts). Many of the major commodity crops produced in the central and mid-southern United States are wind-pollinated (rice, corn, grain sorghum, wheat), or are sufficiently self-fertile (soybeans, cotton), and so do not require bee pollination in order to produce yield. Beekeepers still rely on these agricultural landscapes to support honey bee colonies when not …

Thermometry Via Diffusion In Ferrous Core-Shell Nanoparticles For Induction Heating Applications, Hayden Carlton

Graduate Theses and Dissertations

Induction heating causes the release of enormous amounts of heat from dispersed magnetic nanoparticles. While the rate of heat transfer can be easily quantified calorimetrically, measuring the temperature of the nanoparticles on the nanoscale presents experimental challenges. Fully characterizing the temperature and thermal output of these magnetic particles is necessary to gauge overall heating efficiency and to provide a more holistic understanding of heat transfer on the nanoscale. Herein, this dissertation seeks to develop a novel nanoparticle thermometry technique, which correlates diffusion behavior in core-shell nanoparticles to local temperature. Initial measurements suggested that heating silica capped ferrous nanoparticles (SCNPs) via …

Habitat Assessment Of Ozark Glades Using Selected Epigeal Predatory Arthropods, Austin Key Jones

Graduate Theses and Dissertations

Epigeal predatory arthropods were collected with pitfall-style traps in nine sandstone glades of varying ecological stages, and management histories, in the Ozarks of Northern Arkansas over three years. These sites were categorized into three Site Types; Intact, high quality glades; Degraded, forest-encroached glades, and Restored glades which had received woody vegetation removal and burning. Collections of ground spiders (Gnaphosidae), predatory ground beetles (Carabidae), and the sole species of scorpion present in the Ozarks, Centruroides vittatus, were reported on as well as the applicability of arthropod collection methods for glade habitat assessment. Habitat characteristics were recorded for each site and analyzed …
