Analyzing Physiological Signals During The Menstrual Cycle: Introducing An Application Of Circular Statistics, Krystal D. Sides

UNF Graduate Theses and Dissertations

Physiological signals are used in engineering and the sciences to determine the state of functionality of certain physiological systems such as the human endometrium. Many women use the basal body temperature method to track ovulation, or their fertile window. However, temperature tracking alone is subject to environmental factors. Non-invasive wearable devices can be tools in recording cycle-related physiological features relevant to women’s health research. This research uses the Empatica E4 wristband to track changes in the physiological features during sleep across the menstrual cycle of ovulating and non-ovulating females. Due to the cyclic nature of menstrual cycles, analytic solutions to …

Sustainable Transportation: Behavioral Analysis Of Working-From-Home And Electric Vehicles Adoption, Zeinab Bayati

UNF Graduate Theses and Dissertations

Sustainable transportation plays a crucial role in mitigating environmental impacts, and this study examines two key aspects, namely working from home (WFH) and the adoption of electric vehicles (EVs), in the context of promoting sustainable practices.

The first part of this thesis focuses on how people's perceptions towards working from home have changed as a result of their experiences during COVID-19. To analyze these changes, a random parameter logit (RPL) model is developed based on a nationwide public dataset collected during the pandemic in the United States. Dependent variable of the model is constructed through comparing data from the first …

Ovulation Prediction Using Random Forest Algorithm On Physiological Data, Kimberly D. Laynes

UNF Graduate Theses and Dissertations

Human infertility rates are on the rise -- studies have shown that one in every four women have trouble conceiving and every year those rates are rising [Halleran22]. This trend motivates procedures such as in-vitro fertilization (IVF) and intrauterine insemination (IUI) to produce a pregnancy. Such procedures are not only intricate and expensive but also carry potential unintended consequences for women's physical and mental well-being. A more profound comprehension of the menstrual cycle and its multiple phases, particularly detecting the ovulation period itself, promotes optimized treatment outcomes and reduces associated risks. To facilitate ovulation detection, new sensing technologies built into …

A paired t test determined the sports nutrition knowledge post test scores were higher than the pretest scores (M = 3.92, SE = .86), t (102) = -9.024, p …

Microbial Communities In The Guana Tolomato Matanzas National Estuarine Research Reserve: An Assessment Of The Responses Of Spartina Alterniflora Epiphytes To Nitrogen Enrichment, And A Characterization Of Benthic Cyanobacterial Diversity, Anne C. Hurley

UNF Graduate Theses and Dissertations

Elevated nitrogen and phosphorus inputs from anthropogenic sources, which can lead to significant increases in algal biomass and changes in algal community composition, poses a serious threat to estuarine ecosystems worldwide. While numerous studies have addressed the impacts of nutrient enrichment on epiphytic algae in seagrass habitats, few have investigated potential nutrient-driven changes to epiphytes on emergent salt marsh plants, such as Spartina alterniflora. Epiphytic microalgae on S. alterniflora play an important role in food availability in salt marsh ecosystems, and epiphytic nitrogen-fixing cyanobacteria also provide an important source of nitrogen for salt marsh consumers. The first study included …

Enhancing Soil Carbon Sequestration Through Grassland Restoration Of Former Row Crop Fields At Irvine Prairie, Joshua Joel Mixdorf

Dissertations and Theses @ UNI

The sequestration of atmospheric carbon into the soil is an important mechanism to combat the current global warming trend and the depletion of soil organic matter. Plants capture carbon from the atmosphere and sequester it in the soil, where it is utilized by soil organisms; these processes increase soil organic matter, decrease the amount of carbon in the atmosphere and fuel microbial respiration that drives nutrient production needed by plants. In this study I measured the accumulation of soil organic matter on land that had been in constant row crop rotation for many years and was converted into prairie in …

The main goals were to establish the most effective management and egg washing procedures to reduce total coliform bacteria load on eggshells and increase egg cleanliness. To determine the methods used for experiments in chapters 3-5, a survey was conducted on egg handling, washing and management techniques in backyard poultry and small-scale producers within the Northeastern U.S. The effect of management practices and egg washing methods on the eggshell cuticle was …

Bee Visitation To Three Clover Species (Trifolium Spp.), Common Selfheal (Prunella Vulgaris) And Creeping Thyme (Thymus Serpyllum), Julia J. Vieira

Open Access Master's Theses

Native bees are experiencing global declines due to multiple factors including habitat loss, pesticide use, pathogens, and climate change. Several recent bumble bee studies across New England have documented declines in species richness throughout the region. Bee visitation to different flower species in bloom concurrently can be influenced by actual floral preferences, timing of nectar and pollen presentation, relative abundances of the flower species, and other factors. I assessed bee abundance, diversity, and selective foraging patterns in southern Rhode Island on four planted flower species: white clover (Trifolium repens L.), medium and mammoth red clover (Trifolium pratense L.), …

Better Solutions To Increasing Covid-19 Vaccine Access: Giving Away Vaccines Rather Than Vaccine Formulas, Tristen Prouse

Honors Program Theses

The debate over giving away the COVID-19 vaccine formulas is a political hot topic. Mention of a Trade-Related Intellectual Property Rights (TRIPS) waiver proposed in early 2021 suggested violating patent law to give away the vaccine formulas. While a tempting option, many problems exist with this solution. Violating patent law to give away the vaccine formulas disincentivizes innovation, undermines confidence in vaccine safety, and harms America’s geopolitical objectives. Patent law can be inefficient and is not the only way to incentivize innovation, but it is here to stay. Instead, the United States should give away vaccines rather than vaccine formulas …

States Of Emergency: Covid-19 And Separation Of Powers In The States, Richard Briffault

Faculty Scholarship

No event in recent years has shone a brighter spotlight on state separation of powers than the COVID-19 pandemic. Over a more than two-year period, governors exercised unprecedented authority through suspending laws and regulations, limiting business activities and gatherings, restricting individual movement, and imposing public health requirements. Many state legislatures endorsed these measures or were content to let governors take the lead, but in some states the legislature pushed back, particularly — albeit not only—where the governor and legislative majorities were of different political parties. Some of these conflicts wound up in state supreme courts.

This Essay examines the states’ …

Publicizing Corporate Secrets, Christopher J. Morten

Faculty Scholarship

Federal regulatory agencies in the United States hold a treasure trove of valuable information essential to a functional society. Yet little of this immense and nominally “public” resource is accessible to the public. That worrying phenomenon is particularly true for the valuable information that agencies hold on powerful private actors. Corporations regularly shield vast swaths of the information they share with federal regulatory agencies from public view, claiming that the information contains legally protected trade secrets (or other proprietary “confidential commercial information”). Federal agencies themselves have largely acceded to these claims and even fueled them, by construing restrictively various doctrines …

Family Law For The One-Hundred-Year Life, Naomi Cahn, Clare Huntington, Elizabeth S. Scott

Faculty Scholarship

Family law is for young people. To facilitate child rearing and help spouses pool resources over a lifetime, the law obligates parents to minor children and spouses to each other. Family law’s presumption of young, financially interdependent, conjugal couples raising children privileges one family form — marriage — and centers the dependency needs of children.

This age myopia fundamentally fails older adults. Families are essential to flourishing in the last third of life, but the legal system offers neither the family forms many older adults want nor the support of family care older adults need. Racial and economic inequities, accumulated …

Attack Of The Clones: Elucidating The Role Of Clonality In The Invasion Success Of Carpobrotus Edulis, Eduardo Luis Cruz

Electronic Theses, Projects, and Dissertations

Transcriptomics is a modern technique in genomics that utilizes RNA sequences to get a snapshot of genetic expression. This is a powerful tool in non-model species lacking a reference genome. Thus, the application of comparative transcriptomics has the potential to help us elucidate the evolutionary mechanisms that facilitate species invasion. Carpobrotus edulis is a prolific and widespread invasive succulent plant belonging to the Aizoaceae family. A native to South Africa, this species has become a dominant invader of many Mediterranean coastal areas. In this study, we leveraged the use of RNAseq to investigate evolutionary changes among invasive populations. RNA-seq data …

Hierarchy, Race & Gender In Legal Scholarly Networks, Nicholson W. Price, Keerthana Nunna, Jonathan Tietz

Articles

A potent myth of legal academic scholarship is that it is mostly meritocratic and mostly solitary. Reality is more complicated. In this Article, we plumb the networks of knowledge co-production in legal academia by analyzing the star footnotes that appear at the beginning of most law review articles. Acknowledgments paint a rich picture of both the currency of scholarly credit and the relationships among scholars. Building on others’ prior work characterizing the potent impact of hierarchy, race, and gender in legal academia more generally, we examine the patterns of scholarly networks and probe the effects of those factors. The landscape …

Breast Density Classification Using Deep Learning, Conrad Thomas Testagrose

UNF Graduate Theses and Dissertations

Breast density screenings are an accepted means to determine a patient's predisposed risk of breast cancer development. Although the direct correlation is not fully understood, breast cancer risk increases with higher levels of mammographic breast density. Radiologists visually assess a patient's breast density using mammogram images and assign a density score based on four breast density categories outlined by the Breast Imaging and Reporting Data Systems (BI-RADS). There have been efforts to develop automated tools that assist radiologists with increasing workloads and to help reduce the intra- and inter-rater variability between radiologists. In this thesis, I explored two deep-learning-based approaches …

Lake Huron Microbial Mats: A Novel Anagnostidinema Species, A Cyanobacteria-Specific It's Motif Slicer, & A Multi-Marker Community Analysis, Callahan Mcgovern

UNF Graduate Theses and Dissertations

A region of Lake Huron near Alpena, Michigan (U.S.A) includes karstic sinkholes with oxygen-poor, sulfur-rich ground water that contain vibrant microbial mats resembling life in early Earth’s shallow seas. We sought to document some of this unique ? diversity including the cyanobacteria, heterotrophic bacteria, and diatoms. Using culture-based investigations, we recovered strains of a novel cyanobacterium, Anagnostidinema visiae, and by employing a polyphasic approach we described this novel species from the Middle Island Sinkhole. In the processes of characterizing this novel species, the challenges of cyanobacterial systematics became evident. This led us to create a bioinformatics tool to help in …

Curriculum Strategy To Increase College Student’S Motivation, Ability And Opportunity Resulting In Reduction In Wasted Food, Sarah D. Brunnig

UNF Graduate Theses and Dissertations

Concerns about Food Loss and Waste (FLW) have been rapidly growing worldwide as it came to be understood how the loss of about one-third of the edible food produced globally leads to environmental damage, leads to loss of about USD 1 trillion and keeps food from hungry people. Consumers in developed countries account for the largest majority of food that is wasted. College presents an excellent opportunity to reach young adults as they are developing their identity, self-efficacy and life skills. Utilizing the Motivation-Ability-Opportunity Framework, this research’s overall goal was to find a Curriculum Strategy to engage allied health students …

Confocal Analysis Of Sindbis Virus In Aedes Aegypti Unveils Novel Infection Site At Pyloric Armature, Katie Gillian Peters

UNF Graduate Theses and Dissertations

Arthropod-borne viruses (arboviruses), such as Sindbis virus (SINV), generate foci of infection within the midgut of viremic blood-fed mosquitoes. Arboviruses can disseminate out of the midgut into the surrounding musculature and hemolymph, eventually making it to the salivary glands where virus can be transmitted by saliva during a subsequent blood-feed. In this study, the virus SINV containing the reporter gene GFP, combined with immunohistochemistry, was imaged using confocal microscopy and used to evaluate the infection within the vector mosquito Aedes aegypti. The spatial distribution of SINV infection revealed two common characteristics of foci generated in the midgut. (1) There …

Triumph After Trauma: A Phenomenological Exploration Into Women Survivor’S Perceptions Of The Influence Of Trauma On Their Leadership, Natalya R. Bannister Roby

UNF Graduate Theses and Dissertations

Most research around trauma is focused on negative life consequences. Although limited, there is research that explores the influence of resilience and how some survivors may experience growth after trauma (Kirschman, 2004). Furthermore, research is limited on how trauma influences the leadership style and career trajectories of women who have overcome trauma. A qualitative phenomenological approach was used as the methodological framework to explore the perspectives of women leaders who identify as survivors or overcomers of trauma. The study participants are women leaders in middle management positions to senior-level executives in educational organizations serving middle and high school students.

Illness Stigma, Social Connectedness, And Health In People Living With Chronic Illness: A Structural Equation Model, Abigail Brooke Crawford

UNF Graduate Theses and Dissertations

The complexity of chronic or unexplained conditions may lead to potential stigma for those suffering long-term symptoms as they do not follow the expected pattern of recovery following diagnosis and treatment. Experiencing such illness-related stigma has potential for leading to a belongingness identity of detachment with implications for health across physical, social, and psychological dimensions. This study aimed to examine the relationship between stigma, social connection, mental health, physical health, and social functioning in a group of 231 participants with ongoing symptoms of chronic illness through structural equation modeling. The fit indices all suggest that the model reasonably fits the …

Running The Gauntlet: Barriers For Black Women Academics In Higher Education Research Productivity, Crishana Dionne Benton

UNF Graduate Theses and Dissertations

Internationally, research productivity bears significance for an institution’s reputation and overall research ranking. Many previous efforts surrounding faculty issues have focused on individual faculty research productivity. This study reimagined the definition of productivity as an academic’s impact on scholarly research, evidenced by their h-index.

At the same time, the need for diversity of faculty populations is becoming more urgent, even in a time when the number of tenure-earning faculty positions is diminishing and those which remain are occupied mainly by white men. To add to the disparities, it is reported that only 4% of full-time faculty are Black women. Black …

The Effect Of Environmental Factors On Movement Patterns And Habitat Use Of Young-Of-The-Year Scalloped Hammerhead Sharks (Sphyrna Lewini) In The Tolomato River Nursery, Matthew Bernanke

UNF Graduate Theses and Dissertations

Various shark populations on the southeastern coast of the United States experienced declines in the late 20^th century, including the scalloped hammerhead shark (Sphyrna lewini). Improved management strategies, implemented in the late 1990s, have helped these populations to recover, but they are still under threat from fishing pressure and habitat loss. In continuing to strive towards population recovery and conservation, it is important to identify Essential Fish Habitat, or habitats that are necessary for the spawning, feeding, breeding, or growth of marine organisms. One such habitat is that of the shark nursery habitat. Nursery habitats are those …

Investigation Of The Segment Polarity Network In The Tardigrade Hypsibius Exemplaris, Taylor R. Harrison

UNF Graduate Theses and Dissertations

Segmentation has facilitated the evolution of the many forms of the panarthropods. Downstream regulation of segmentation is controlled by the highly conserved segment polarity network which includes the genes engrailed (en), hedgehog (hh), wingless (wg), cubitus interruptus (ci), patched (ptc), and smoothend (smo). While a high level of conservation has been seen in both the arthropods and onychophorans, only en has been described in any representatives of Tardigrada. Previous work had already established the loss of wg, which encodes for a Wnt ligand, in the tardigrade H. exemplaris …

Biological Embedding Of Early Trauma: The Role Of Higher Prefrontal Synaptic Strength, Amanda J F Tamman, Lihong Jiang, Christopher L Averill, Graeme F Mason, Lynnette A Averill, Chadi G Abdallah

Staff and Researcher Publications

Background: Early trauma predicts poor psychological and physical health. Glutamatergic synaptic processes offer one avenue for understanding this relationship, given glutamate's abundance and involvement in reward and stress sensitivity, emotion, and learning. Trauma-induced glutamatergic excitotoxicity may alter neuroplasticity and approach/avoidance tendencies, increasing risk for psychiatric disorders. Studies examine upstream or downstream effects instead of glutamatergic synaptic processes in vivo, limiting understanding of how trauma affects the brain.Objective: In a pilot study using a previously published data set, we examine associations between early trauma and a proposed measure of synaptic strength in vivo in one of the largest human …
