Handheld X-Ray Fluorescence (Hhxrf) As A Non-Destructive Method For Trace Element Analysis Of Ancient Maya (Pre-Conquest 800 Bc - Ad950) Teeth From Altun Ha, Belize, Griffon G. Binkowski

Honors Undergraduate Theses

In anthropology, elemental analysis of bone and teeth can provide significant details about an individual’s life history, such as diet, toxicity exposure, residency, and migration patterns. Intra-individual comparisons can help to gather information about a single individual’s life, while inter-individual comparisons can help illustrate a community’s life history during these periods. However, current methods of elemental analysis commonly involve the destruction of skeletal samples, which can damage a collection’s integrity and be perceived as disrespectful by descendant communities. Preliminary research has validated handheld x-ray fluorescence spectrometry (HHXRF) as an accurate and reliable method of analysis appropriate for determining the elemental …

Clostridioides Difficile: Identification Of Rival Organisms & Evaluation Of Non-Antibiotic Treatment Implementation, Justin Davis

Honors Undergraduate Theses

Clostrioides difficile is a common cause of nosocomial (hospital-acquired) infections. Patients receiving antibiotic treatment experience dysbiosis of gut microbiota, and C. difficile, normally held in check by the various other organisms, takes this opportunity to propagate. Symptoms of infection generally include diarrhea, colitis, dehydration, and fever. Understanding that C. difficile generally only causes illness when it is the dominant bacterium (i.e. when growth is relatively unchecked by other microbes), it is appropriate to investigate potential competitive organisms that may be introduced after antibiotic courses or during active C. difficile infection to effectively displace it. Fecal samples from the University …

Studying Implicit Racial Bias In Breast Cancer Screening, Diagnosis, And Treatment: A Scoping Review, Lillian C. Nguyen

Honors Undergraduate Theses

Breast cancer remains a significant public health concern worldwide, with persisting disparities in several aspects of breast cancer care. Implicit bias has emerged as a potential contributor to these disparities. While previous research has examined implicit bias in healthcare, particularly in the context of racial and ethnic disparities, no review has been conducted to examine the association of physician implicit bias and breast cancer care. There remains a need for further investigation into its role in breast cancer care. This scoping review aims to systematically analyze the existing literature on physician implicit bias in breast cancer care to discern its …

Tim/Tam Receptors: A Potential Biomarker For Predicting Sensitivity To Zika Virus-Induced Oncolysis In Non-Small Cell Lung Cancers, Shankari Somasekar

Honors Undergraduate Theses

Non-small cell lung cancers (NSCLC) constitute 80-85% of lung cancers and are the leading cause of cancer-related deaths globally. The most common cause is prolonged smoking. Current treatment options for NSCLC include surgery, radiation, chemotherapy, targeted drug therapy, and immunotherapy. Although these medications are effective in the short term, patients often face issues of drug resistance and debilitating side effects with prolonged use. Currently, the use of Zika virus (ZIKV) is being researched as a possible alternative treatment for cancer, which minimizes side effects and the risk of drug resistance. TIM/TAM proteins are identified as the putative ZIKV receptors on …

How Hormonal Contraceptives Influence Injury In Female Athletes: A Systematic Review, Ashley V. Malvita

Honors Undergraduate Theses

Research indicates that female athletes have a higher risk of musculoskeletal injuries. Hormone fluctuations throughout the different periods of the menstruation cycle impacts the risk of injuries for women. Contraceptive use, most used in the form of an oral contraceptive pill, directly effects hormones and menstrual cycle related symptoms, with evidence of ameliorating some symptoms. Oral contraceptive use is suggested to influence musculoskeletal injuries in female athletes. However, there is little research and data that explores the direct relationship between oral contraceptive use and the injury rates of female athletes. Within this systematic review, five articles investigating this relationship fulfilled …

The Effect Of Different Music Genres On Listeners' Emotions, Benjamin N. Rosenberg

Honors Undergraduate Theses

Music has been shown to have definitive effects on the emotions of listeners, but the effects of different genres of music have been less frequently studied. The purpose of this study was to examine three different genres of music (pop, metal, and EDM), and the different effects on listeners’ emotions that they would have. College students (n = 191), completed a questionnaire assessing genre preference and emotions, before listening to a selection of songs from one of the three genres. Afterwards, they reported their emotions once more. Metal music was found to cause an increase in negative emotions, while …

Florida Queer K12 Teachers Perceptions Of School Climate Under “Don’T Say Gay”, Katherine E. Foley

UNF Graduate Theses and Dissertations

Florida's newest legislation leaves many Florida queer teachers feeling marginalized and unprotected in the classroom (Block, 2022). The “Parental Rights in Education” Bill (FL HB 1557 and FL HB 1069), infamously renamed “Don’t Say Gay”, was created ostensibly to help protect parental rights and choices in education. The new law prohibits the discussion of gender identity and sexual orientation in kindergarten through twelfth grade classrooms. “Don’t Say Gay” provides vague guidelines for queer teachers on approaching topics like sexual orientation and gender identity. Despite the evidence that queer teachers who are open and honest about their identity often find themselves …

An Enhanced Evaluation Of Bioslurry For Use In Coastal Erosion Mitigation, Megan Elizabeth Dunton

UNF Graduate Theses and Dissertations

This paper discusses the treatment of Florida beach sand by surface percolating Bioslurry, a microbially-induced calcite precipitation (MICP) variant that was developed and refined in recent years. Researchers examined how variations in pore volume and surface area affected the cemented depth of soil treated via surface percolation. Results suggested that while the pore volume is an important factor that governs cementation in soil treated via surface percolation, it does not appear to be the only controlling factor and treatment volume per unit surface area is another important factor to consider when treating soil with Bioslurry using surface percolation. The implications …

The Effects Of Human-Driven Land Use Change On American Alligator (Alligator Mississippiensis) Nesting Patterns, Madison Wallwork

UNF Graduate Theses and Dissertations

American alligators (Alligator mississippiensis) have received little scientific attention in the context of human-driven land use change. The goal of my study is to investigate how land use change may be affecting the spatial ecology of alligator nesting in Florida. Areas directly impacted by humans are growing rapidly in Florida, yet the impacts of this land use change on alligator populations and reproduction are largely unknown. Alligators are ecosystem engineers and apex predators, and their nests often double as nests for other reptilian species. Therefore, it is imperative that we understand how human-driven land use change may be impacting …

Investigating The Role Of Tesserae In Energy Absorption In Shark Cartilage, Molly Dobrow

UNF Graduate Theses and Dissertations

Unlike mammals, shark endoskeletons are composed of cartilage, which is less stiff compared to bone. Despite this structural disadvantage, sharks have risen to become apex predators, with reported maximum posterior bite force estimates approximating 5914 N in bull sharks. Shark jaws are estimated to undergo high cycle loading within the organism’s lifecycle without evidence of failure. Fatigue resistance may relate to mineral distribution within a component of the endoskeletal system – tesserae. Tesserae are thin, roughly hexagonal tiles composed of calcium phosphate hydroxyapatite (HA) crystals and grow by accretion to eventually surround the hyaline cartilage core. Though tesserae dimensions are …

Power Of Partnership: The Effects Of Parent Training In Aided-Language Input On The Use Of Core Vocabulary Boards In The Homes Of Preschool Children: A Program Evaluation, Stephanie Jean Smith

UNF Graduate Theses and Dissertations

Augmentative and Alternative Communication (AAC) systems play a crucial role in enhancing communication, language development, and learning for children with complex communication needs (CCN). Research suggests that AAC can significantly improve interaction with communication partners and mitigate risks in various developmental areas such as functional communication skills, speech, social engagement, and academic participation.

Early intervention is paramount for children with CCN to foster speech and language development, enabling them to express needs, interact socially, and lay the groundwork for future language skills. Introducing AAC systems early on and ensuring frequent exposure are essential for natural integration. Parents and caregivers must …

Exploring The Behavioural And Neural Bases Of Impulsivity In A Transdiagnostic Approach Relevant For Addiction., Kenza Kadri

School of Psychology Theses

This thesis aims to investigate the behavioural and neural basis of impulsivity, which is known to be a risk factor in the development of psychiatric disorders such as addiction. To tackle this issue, the thesis uses neuroimaging, behavioural, and machine-learning techniques to identify transdiagnostic markers of impulsivity and their relationship with striatal connectivity and decision-making variability. This thesis was divided into two studies. The first one aims to associate a set of transdiagnostic markers relevant to addiction with the connectivity profiles of the striatum, which is known to be implicated in processes of reward, motivation, and decision-making. In particular, this …

Journal of Human Services: Training, Research, and Practice

This research study examines mental health practitioners’ level of trauma knowledge and trauma treatment self-efficacy pre- and post-EMDR therapy training in Texas. The purpose is to determine if practitioners' self-perception of efficacy in treating trauma and trauma knowledge will improve after completing EMDR training. The practitioner sample (N = 113) is from an EMDR trainer who conducted six EMDR trainings in Texas. Descriptive, correlational, and paired t-test statistical procedures were implemented to analyze the data for the study. The results show that practitioners’ self-perception of competence and knowledge could be attributed to their years of clinical experience treating clients with …

Describing The Experiences Of Fulfillment And Stress In Coptic Orthodox Priests, Dr. Martha Salama

Journal of Human Services: Training, Research, and Practice

This qualitative study was conducted to understand how Coptic Orthodox priests describe their experiences of fulfillment and/or stress with their work. While many Christian leaders such as pastors, reverends, and clergy helping to serve their church members are represented in the literature, there is limited research on the roles and experiences of the Coptic Orthodox priesthood serving their communities. The Coptic church has been around for centuries, and the church has a history of religious persecution. The research question was “how do Coptic Orthodox priests describe their experiences of fulfillment and/or stress with their work?” The research methodology used in …

Durability, Flexibility And Plasticity In The U.N. Convention On The Law Of The Sea, Sean Murphy

GW Law Faculty Publications & Other Works

The overall resilience of the U.N. Convention on the Law of the Sea during the forty years since its adoption in 1982—its durability, its flexibility and its plasticity in the face of myriad challenges that have unfolded over time—is largely attributable to certain design features within the Convention, to a willingness to ‘bend’ the Convention toward practical outcomes when necessary, and to the foresight of the drafters in closely tying the Convention to other agreements and standards, as well as to the general field of international law, so that the Convention might evolve as the world evolves. There are risks …

Bystanders To A Public Health Crisis: The Failures Of The U.S. Multi-Agency Regulatory Approach To Food Safety In The Face Of Persistent Organic Pollutants, Katya S. Cronin

GW Law Faculty Publications & Other Works

Per- and polyfluoroalkyl substances (“PFAS”) are devastating our food systems and our health. Recent studies link even small exposure to PFAS to a host of adverse health outcomes, including cancer, autoimmune diseases, thyroid disease, liver damage, childhood obesity, infertility, and birth defects.

Food consumption is a primary route of PFAS exposure. PFAS are omnipresent at dangerous levels in our marine and agricultural environments, including in water, soil, fertilizers, compost, and air. From there, they can find their way into virtually every plant, fish, animal, and animal product, and ultimately (in the greatest concentration) into the consumer. In addition, PFAS-laden food …

Why Sustainable Procurement? Read All About It, Steven L. Schooner

GW Law Faculty Publications & Other Works

As procurement professionals (knowingly or unknowingly) await regulations promulgated in an effort to adapt to and mitigate climate change, significant opportunities exist within current federal regulations and policy to affect change. For now, the burden to stimulate innovation falls upon procurement professionals, individually, and collectively. In that context, information is power. What better place to start than with a good book?

With an eye towards informing productive conversations across the federal acquisition community about evolving expectations, practices, and policies in sustainable procurement, this article suggests some reading from the massive and diverse body of work related to climate change.

The Stereological And Morphometrical Investigation Of Pars Lumbalis Of The Spinal Cord Innew Zealand Rabbit, Berna Duman, İftar Gürbüz

Turkish Journal of Veterinary & Animal Sciences

In the study, 12 (6 females, 6 males) healthy adult New Zealand rabbits were used to examine the morphometrical andstereological values. White matter, gray matter and total segment volume of the segments in the pars lumbalis were calculated byCavalieri’s principle. The findings were grouped according to sexand statistically evaluated. As a result, 38% of the length of the spinalcord in rabbits belonged to the pars lumbalis. The morphometric parameters were not statistically different between male and femalerabbits (p > 0.05). The segment with the biggest volume was L5. White matter’s greatest volume was the L4 segment. The volume of graymatter was …

Characterization Of Tonneau1 Recruiting Motif Proteins And Ton2 Signaling Functions, Tyler Falk

Theses and Dissertations

Plants cells are fixed in place. As a result they have to carefully divide in order to function properly. Plants use a number of complex microtubule arrays to ensure proper division and orientation including the preprophase band (PPB) and the phragmoplast. The PPB orients the cell prior to division and marks the cortical division site, which is where the phragmoplast is guided to. The phragmoplast is a dynamic microtubule array that builds the cell plate which later becomes the cell wall that divides daughter cells. Proteins involved with PPB formation include Tonneau1 (TON1) and Tonneau2 (TON2) which localize to and …

Food For Thought: Fabricating The Cannibal In Colonization, Hannah Dubrovich

Theses and Dissertations

Anthropophagy means people-eating, as does cannibal, but the terms are not synonymous. After Europeans landed in the Americas, Christopher Columbus coined the word cannibal. Despite the two terms having similar base definitions, there are additional connotations associated with cannibal. The way in which cannibalism has been thought about by Western cultures is not about the act of people-eating, but the constructed character of the cannibal as a “savage” Other created through colonization. In addition to the term's associated meaning being cemented during this time, colonizers used the term as a tool to Other Native peoples and aid in colonization. It …

Ergot Alkaloid Consumption Alters Serotonin Receptor-Induced Vasoactivity In Ovine Umbilical Vasculature, James L. Klotz, Jessica L. Britt, Maslyn A. Greene, Coral Kent-Dennis, Susan K. Duckett

Animal and Food Sciences Faculty Publications

Consumption of ergot alkaloids during the second half of gestation has been shown to decrease umbilical artery vasoactivity resulting in decreased birth weights. Negative vascular effects of ergot alkaloids are mediated predominantly through serotonergic and adrenergic receptors in other tissues. Vasoactivity of serotonin (5-HT) receptors 5-HT_2A and 5-HT_1B/1D in umbilical artery and vein from ewes receiving endophyte-infected seed (E + 1.77 mg ergovaline/hd/d) or a control total mixed ration (CON; 0 mg ergovaline/hd/d) tall fescue seed at d-110 and d-133 of gestation was evaluated. Gravid reproduction tracts were collected from ewes. Two-mm sections of umbilical artery and vein …

The objective of this study was to investigate the effect of essential oil (EO) supplementation on insulin sensitivity (IS) and the plasma metabolome in insulin dysregulated (ID) horses. Horses were blocked by degree of IS and assigned randomly to treatment: oral daily bolus (50 mL) of either a plant derived EO supplement or carrier (CON). Mares were housed in dry lots with ad libitum access to grass hay and supplemented individually twice daily with a concentrate to meet nutrient requirements for mature horses. Before and after 6 wks of treatment, mares underwent a combined glucose-insulin tolerance test (CGIT) and an …

Ovotransferrin-Depleted Egg White Hydrolysate Reduces Blood Pressure In Spontaneously Hypertensive Rats, Fatemeh Ashkar, Hongbing Fan, Zihan Wang, Ilekuttige Priyan Shanura Fernando, Jianping Wu

Animal and Food Sciences Faculty Publications

Egg whites contain a variety of biologically active proteins and are a good source of bioactive peptides. Egg white hydrolysate prepared by thermoase (EWH) possesses antihypertensive effects. Our recent study showed that egg white proteins, after depleting ovotransferrin, also contained many angiotensin-converting enzyme (ACE)-inhibitory peptides after hydrolysis using thermoase. In the present study, we aimed to explore the antihypertensive effect of the ovotransferrin-depleted egg white hydrolysate prepared by thermoase (OD-EWH) in spontaneously hypertensive rats, using EWH as the reference. The animals were orally administered with either hydrolysate at a dose of 1 g/kg body weight/d over 9 d. OD-EWH treatment …

Effects Of A Second Iron-Dextran Injection Administered To Piglets During Lactation On Differential Gene Expression In Liver And Duodenum At Weaning, James L. Pierce, J. Wesley Lyons, Tyler B. Chevalier, Merlin D. Lindemann

Animal and Food Sciences Faculty Publications

Six female littermate piglets were used in an experiment to evaluate the mRNA expression in tissues from piglets given one or two 1 mL injections of iron dextran (200 mg Fe/mL). All piglets in the litter were administered the first 1 mL injection < 24 h after birth. On day 7, piglets were paired by weight (mean body weight = 1.72 ± 0.13 kg) and one piglet from each pair was randomly selected as control (CON) and the other received a second injection (+Fe). At weaning on day 22, each piglet was anesthetized, and samples of liver and duodenum were taken from the anesthetized piglets and preserved until mRNA extraction. differential gene expression data were analyzed with a fold change cutoff (FC) of |1.2| P < 0.05. Pathway analysis was conducted with Z-score cutoff of P < 0.05. In the duodenum 435 genes were significantly changed with a FC ≥ |1.2| P < 0.05. In the duodenum, Claudin 1 and Claudin 2 were inversely affected by + Fe. Claudin 1 (CLDN1) plays a key role in cell-to-cell adhesion in the epithelial cell sheets and was upregulated (FC = 4.48, P = 0.0423). Claudin 2 (CLDN2) is expressed in cation leaky epithelia, especially during disease or inflammation and was downregulated (FC = -1.41, P = 0.0097). In the liver, 362 genes were expressed with a FC ≥ |1.2| P < 0.05. The gene most affected by a second dose of 200 mg Fe was hepcidin antimicrobial peptide (HAMP) with a FC of 40.8. HAMP is a liver-produced hormone that is the main circulating regulator of Fe absorption and distribution across tissues. It also controls the major flows of Fe into plasma by promoting endocytosis and degradation of ferroportin (SLC4A1). This leads to the retention of Fe in Fe-exporting cells and decreased flow of Fe into plasma. Gene expression related to metabolic pathway changes in the duodenum and liver provides evidence for the improved feed conversion and growth rates in piglets given two iron injections preweaning with contemporary pigs in a companion study. In the duodenum, there is a downregulation of gene clusters associated with gluconeogenesis (P < 0.05). Concurrently, there was a decrease in the mRNA expression of genes for enzymes required for urea production in the liver (P < 0.05). These observations suggest that there may be less need for gluconeogenesis, and possibly less urea production from deaminated amino acids. The genomic and pathway analyses provided empirical evidence linking gene expression with phenotypic observations of piglet health and growth improvements.

Role Of Ε-Poly-Lysine In Mixed Surimi Gel, Zhaorui Li, Guangcan Liang, Yungang Cao, Fang Yuan, Miaomiao Liu, Zelong Liu, Youling L. Xiong

Animal and Food Sciences Faculty Publications

The effects of different concentrations of ε-Poly-lysine (ε-PL: 0.005%, 0.01%, 0.02%, 0.04%, and 0.06%) on the marine fish-egg white protein compound gels, treated with 0.4% TGase induced cross-linking were systematically investigated under low salt and phosphorus-free conditions (0.5% NaCl). The results showed the combination of ε-PL and TGase had a synergistic effect on improving sectional gel properties of composite surimi samples. Wherein the rheological, LF-NMR, and SEM results confirmed that the addition of ε-PL based on 0.4% TGase significantly improved the gel strength (to the highest value: 781.63 g·cm), apparent viscosity, and G 'value of the composite surimi sample, as …
