Gulf Stream Intrusions As Conduits For Larval Fishes Along Florida’S East Coast, Caroline Woodward
Gulf Stream Intrusions As Conduits For Larval Fishes Along Florida’S East Coast, Caroline Woodward
Electronic Theses and Dissertations 2020 - Present
The mechanisms of larval fish transport have been rigorously studied in the past several decades, building foundational knowledge of key biological and environmental factors with which to inform decisions about species management. This study has been built upon information gained from previous studies to further elucidate the processes involved at the recruitment stage of larval fishes. Vertical swimming behaviors of larval fishes enable deliberate orientation within the water column to allow organisms of limited mobility greater control over their horizontal movements. Vertical accumulation patterns of larvae are found to be tightly dependent on the strength of stratification within the water …

This thesis outlines the cultural and literary interpretations of Haitian folktales among Haitians, Haitian Americans, and Americans of non-Haitian descent. This thesis seeks to explain how folktales can be used to highlight cultural identity through symbolic analysis, cultural reflexive theory and a cross-cultural analysis model. The nuanced differences found in the reception of the folktales that are associated with the characters of Uncle Bouki and Ti Malis by the three research groups forms the basis of this thesis research design. The characters of Uncle Bouki and Ti Malis are, in effect, cultural literary examples of how folktales could be used …
Head Direction Cell Network And Spatial Navigation: Effects Of Silencing Anterodorsal Thalamic Neurons Using Dreadds, Brittany Nicole Crafton
Head Direction Cell Network And Spatial Navigation: Effects Of Silencing Anterodorsal Thalamic Neurons Using Dreadds, Brittany Nicole Crafton
Electronic Theses and Dissertations 2020 - Present
While the thalamus and hippocampus are generally understood to contribute to mammalian spatial navigation, the degree to which thalamic input contributes to representations of space during navigation remains unclear. Specifically, anterior dorsal thalamic nuclei (ADN) provide a relational or directional framework known as the head direction (HD) network, which is hypothesized to play a significant role in guiding hippocampal-dependent navigation. The current study focuses on the contribution of the ADN to direction and place-dependent spatial navigation in adult male C57BL6J mice. An inhibitory chemogenetic (hM4Di) receptor was bilaterally expressed in the ADN after viral stereotaxic injection. Mice were trained in …
Hyposalinity Stress Tolerances Of The Corals Montastraea Cavernosa And Porites Astreoides In Southeast Florida And Implications For Coastal Freshwater Management, Haley A. Davis
Electronic Theses and Dissertations 2020 - Present
Coastal development shifts natural hydrology through water redirection, increased impervious surfaces, and increased connectivity to the coastal ocean through inlets. In Southeast Florida, watershed alterations can cause flash-freshening in nearshore coastal habitats, threatening coral reef ecosystems. This study assessed the hyposalinity tolerance threshold of two prominent scleractinian corals in Southeast Florida. In a series of experiments, we determined that Montastraea cavernosa corals have an LC50 of 19 PSU but can survive for at least 21 days at an intermediately stressful salinity of 25 PSU. Porites astreoides corals demonstrated an LC50 of 19 PSU, but experienced mortality when exposed to 25 …

Immersive Journalism: An Overview, Palak Barmaiya
Electronic Theses and Dissertations 2020 - Present
This thesis provides an overview of immersive journalism (IJ), focusing on its theoretical and conceptual framework, objectives, ethical concerns, and evolving landscape. IJ is defined as the production of news in a form in which people can gain first-person experiences of the events or situation described in news stories through the use of immersive technologies, including virtual reality, augmented reality, and mixed reality. While the initial objective of IJ was to enhance empathy and transport users to distant places, recent scholars note the limitations and challenges of this approach. Therefore, media outlets are shifting from empathy-based journalism to other objectives. …
Investigating The Potential Of Amine-Grafted Silica Materials For Simultaneous Removal Of Carbon Dioxide, Water Vapor, And Hydrogen Sulfide From Landfill Gas, Dung Lam
Electronic Theses and Dissertations 2020 - Present
Amine-grafted silica (i.e., aminosilicas) was investigated for single-stage landfill gas purification via simultaneous removal of CO2, H2S, and water vapor. Aminosilica materials were synthesized by covalent triamine grafting onto mesoporous silica with custom amounts of water and amine. Screening adsorption experiments were completed in dry 30 vol.% CO2 in N2 at 40 °C and assessed using thermogravimetric analysis. Materials with equilibrium CO2 uptakes greater than 1.5 mmol/g were chosen for CO2 adsorption kinetics assessments. The highest-performing aminosilica achieved fast CO2 adsorption by reaching 80% of its equilibrium uptake in one minute. This material also maintained 100% of its initial CO2 …

Accent Services: Considering The Perspectives Of Non-Native Speakers Of English For A Culturally Affirming Practice, Kristopher Kilgallon
Accent Services: Considering The Perspectives Of Non-Native Speakers Of English For A Culturally Affirming Practice, Kristopher Kilgallon
Master's Theses and Doctoral Dissertations
Accent “modification” is a type of service offered by speech-language pathologists (SLPs) that is intended to, among other things, help speakers improve their intelligibility in a target second language. This area of practice has been, and continues to be, a controversial topic amongst scholars and practitioners. To explore and understand the perspectives of non-native speakers of English regarding their participation in accent services, the present study employed a qualitative research design using individual, semi-structured interviews. Ten adult non-native speakers of English (female: n = 7; male: n = 3), with ages between 28 and 47 years old (M = …
Soil And Compost Tea: A New Restoration Technique?, Carol E. Day
Soil And Compost Tea: A New Restoration Technique?, Carol E. Day
Master's Theses and Doctoral Dissertations
Historically, prairie restorations have lacked the plant diversity seen in remnant prairies. Most restoration practices focus on reestablishing the plant community but overlook the soil microbial community even though microbes are critical to habitat functioning. Developing techniques that increase soil microbes in prairie restorations is critical to ensuring diverse restored habitats. We compared how microbial communities differed between remnant and restored prairie sites. We also investigated if soil and compost teas could be used to reintroduce microbes to restored prairie soil and if the teas affected native plant establishment. We found significant differences in the levels of bacterial taxa between …
Investigating Sources Of Microplastics And Effects Of Plastic Pollution On Biofilm Function In The Huron River, Sadie Baker
Investigating Sources Of Microplastics And Effects Of Plastic Pollution On Biofilm Function In The Huron River, Sadie Baker
Master's Theses and Doctoral Dissertations
Plastics are a global environmental threat due to mass production and the many unknowns regarding the long-term effects of plastic pollution in the environment. Microplastics (MPs) are plastic particles less than 5 mm in size, and they have become ubiquitous in aquatic ecosystems. MPs enter aquatic ecosystems through non-point sources such as urbanization, runoff, or atmospheric fallout or through point-sources such as wastewater treatment plants (WWTPs). To determine MP sources in the Huron River, we evaluated MP load (MPs/day) upstream and downstream from urban centers (Ann Arbor and Ypsilanti) and the Ann Arbor WWTP. The average MP load among sample …
A Critical Race Critique Of Campus Climate And Belonging For First-Generation Students Of Color At Historically Black Colleges & Predominately White Institutions, Samantha Gale Aaron
A Critical Race Critique Of Campus Climate And Belonging For First-Generation Students Of Color At Historically Black Colleges & Predominately White Institutions, Samantha Gale Aaron
Master's Theses and Doctoral Dissertations
The purpose of this research is to assess whether and how higher education campus climate, policy, and practice influence belonging for first-generation students of color. Through the lens of critical race theory, the study further juxtaposes those experiences through the testimony of students at predominantly White institutions (PWIs) and historically Black colleges and universities (HBCUs). Grounded theory informed my qualitative survey and interview tools through which I examined belonging through three standards: social, which explored belonging through peers, groups, and the environment; personal, which explored belonging through the respondent’s thoughts, feelings, and emotions; and institutional, which explored belonging through practice, …

Faculty, Staff and Students Publications
Human respiratory syncytial virus (RSV) is a major cause of lower respiratory infection. Despite more than 60 years of research, there is no licensed vaccine. While B cell response is a major focus for vaccine design, the T cell epitope profile of RSV is also important for vaccine development. Here, we computationally predicted putative T cell epitopes in the Fusion protein (F) and Glycoprotein (G) of RSV wild circulating strains by predicting Major Histocompatibility Complex (MHC) class I and class II binding affinity. We limited our inferences to conserved epitopes in both F and G proteins that have been experimentally …

The Impact Of Bowl Feeding On Infant Muscle Activity And Kinematics - An Executive Summary, Kendall Steer
Williams Honors College, Honors Research Projects
Addressing difficulties with swallowing is a small, yet critical portion of a speech-language pathologist’s role. Infants often experience challenges associated with swallowing safely, yet the ability of SLPs to prescribe effective interventions is limited by the lack of knowledge on how anatomy and physiology interact to drive these challenges. The goal of my Honors Research Project is to address this lack of knowledge by determining how the infant pig tongue moves during feeding from a bottle versus drinking from a bowl, as well as how the muscles controlling the tongue differ in these behaviors. I used infant pigs for this …
Amphisbaenian Head Movement And Burrowing Forces In Damp Granular Media, Jacob Newell
Amphisbaenian Head Movement And Burrowing Forces In Damp Granular Media, Jacob Newell
Williams Honors College, Honors Research Projects
Damp granular media is a difficult environment to study because it is both practically complex and it lacks equations which fully describe its behavior. In this study, an oscillatory lateral head movement and its effects while penetrating damp granular media were tested using a robophysical model. This experimental research was inspired by the burrowing behavior of the clade Amphisbaenia, a group of usually limbless squamates that employ a variety of different burrowing behaviors, but it can apply to a wide range of burrowers. This research could help with both human burrowing technologies and the further investigation of animal behaviors.

The Effects Of Sex On Zebrafish Bone Metabolism, Simon Bagatto
The Effects Of Sex On Zebrafish Bone Metabolism, Simon Bagatto
Williams Honors College, Honors Research Projects
I investigated the effects of diet and sex on zebrafish bone metabolism. Zebrafish were subjected to either a high-calorie or low-calorie diet over a five-week period. After this diet, zebrafish scales were used to measure alkaline phosphatase (ALP) and tartrate-resistant acid phosphatase (TRAP) enzyme activity with a fluorescent substrate. The enzyme activities were markers of the osteoblasts (ALP) and the osteoclasts (TRAP). These data were compared among sex and diet of the zebrafish using a repeated measures ANOVA statistical test. I also measured the number of resorption lacunae per scale (another indicator of osteoclast activity). The results showed higher TRAP …

Substance use disorders and addiction have become increasingly serious problems in the United States. Diseases of this nature revolve around problematic patterns of substance use and abuse of alcohol, illicit drugs, prescription drugs, and over-the-counter medications. Substance use disorders are not limited to a certain demographic, which makes treatment of these illnesses complicated and multifaceted (Argyriou et al., 2017). This review paper will focus on age-related effects on substance use, and how age is consequential to the effectiveness of drug addiction treatment. The literature review focuses on the onset and progression of substance use disorders and treatment for these disorders …
Reducing Placental Oxidative Stress In A Rat Model Preeclampsia Using Vegfr2 Nanoparticles, Sophia Ganios
Reducing Placental Oxidative Stress In A Rat Model Preeclampsia Using Vegfr2 Nanoparticles, Sophia Ganios
Williams Honors College, Honors Research Projects
Preeclampsia is a complication of pregnancy, where the placenta lacks sufficient blood flow due to abnormal formation of the vascular endothelial cells. This results in hypertension and increased reactive oxygen species, causing oxidative stress. The VEGF (vascular endothelial growth factor) helps develop new growth, so by increasing the receptors VEGFR2 by injection of LTP nanoparticles into the uterine wall of RUPP rats, one can see if there would be improvement in the otherwise reduced uterine pressure pregnant rat. This would be confirmed by the 8-isoprostane test, which measures oxidative stress.
The Role Of Symbolic Politics In Shaping Political Attitudes: A Study Of Trump And Biden's Campaign Speeches, Nimra Asif
The Role Of Symbolic Politics In Shaping Political Attitudes: A Study Of Trump And Biden's Campaign Speeches, Nimra Asif
Williams Honors College, Honors Research Projects
In this study, five speeches by Donald Trump and six by Joe Biden were comprehensively analyzed for their symbolic politics on immigration and social issues. The data revealed a consistent trend, with Trump featuring a greater number of mentions in comparison to Biden—66 and 26, respectively. Furthermore, Trump's symbolic politics exhibited a predominantly negative tone, while Biden's approach was predominantly positive. The results of this analysis confirm my hypotheses, highlighting notable disparities in the rhetoric employed by each candidate. Trump amplified a negative outlook on social issues and immigration, whereas Biden strategically mentioned and positively framed these issues. This research …

This thesis addressed two challenging aspects of microplastic research, including the quantification of microplastics in organic-rich water, and the investigation of how microplastics impact microorganisms and related nutrient-cycling. Two projects were designed and executed to address specific research objectives relating to these broad topics. The first objective was to develop and implement methods to determine the effectiveness of microplastic removal across the natural treatment systems at the Arcata Wastewater Treatment Facility (AWTF). The second objective was to observe how microplastics found in domestic wastewater impact the bacterial communities and nitrogen cycling in freshwater treatment wetland sediment through a bench-scale experiment, …
Effect Of In Situ Experimental Heating Of Artificial Mytilus Californianus Beds On Associated Invertebrate Communities In Northern California, Claire C. Windecker
Effect Of In Situ Experimental Heating Of Artificial Mytilus Californianus Beds On Associated Invertebrate Communities In Northern California, Claire C. Windecker
Cal Poly Humboldt theses and projects
With the continued progression of climate change, the role of foundation species as mediators of temperature stress for species living on and within them has become increasingly important. In the intertidal zone, a major foundation species is the California mussel, Mytilus californianus, which can help to limit thermal stress for species that live among aggregations of these mussels. The ability of mussels to limit thermal stress as temperatures increase, however, is still unclear. This study sought to experimentally manipulate surface temperatures of artificial mussel beds in situ to examine the effects that increased surface heating at a single site …
Habitat Selection And Habitat Use Of Gray Foxes (Urocyon Cinereoargenteus) On Trespass Cannabis Grows., Haley-Marie R. Jones
Habitat Selection And Habitat Use Of Gray Foxes (Urocyon Cinereoargenteus) On Trespass Cannabis Grows., Haley-Marie R. Jones
Cal Poly Humboldt theses and projects
Trespass cannabis grow sites, otherwise known as illegal cultivation sites on public lands, are extremely hazardous to the environment and can severely impact wildlife movement and behavior. Trespass grow sites are dangerous to wildlife as they negatively impact the quality of habitat and wildlife behavior through habitat modification, pesticide use, discarding of trash, and poaching on national forests. I researched gray fox habitat selection and habitat use at six different grow sites in the Klamath National Forest and Shasta-Trinity National Forest in northwestern California. I deployed GPS collars on three gray foxes at two of those grow sites and three …
Neural Crest Cell Migration And Developmental Origin Of Bony Scutes In White Sturgeon (Acipenser Transmontanus), Melody Tew
Cal Poly Humboldt theses and projects
Neural crest cells (NCCs) and mesodermal somites independently produce embryonic mesenchyme as a precursor to the chondrocytes and osteocytes of the vertebrate skeleton. In mammals and teleosts, NCCs only contribute to the dermal cranial skeleton, while the mesodermal somites and lateral plate mesoderm form the entire dermal and endochondral postcranial skeleton. In sharks, NCCs contribute to both the cranial and trunk integumentary skeleton. This suggests that contribution of the trunk neural crest mesenchyme to the integumentary skeleton was an ancestral condition for all vertebrates that was lost over evolutionary time in the osteichthyan lineage, but the evolutionary timing of this …

Sympatric Carnivores And Vegetation Structure Influence The Distribution And Abundance Of Humboldt Martens In Northern California, Erika L. Anderson
Cal Poly Humboldt theses and projects
The Humboldt marten (Martes caurina humboldtensis) is a species facing conservation concern in Oregon and California. Historical populations were subjected to unregulated fur trapping and timber harvest throughout the late 19th and early 20th centuries leading to a 90% decline in their distribution. As such, the Humboldt marten is listed as a state endangered species in California, and the analogous ‘coastal marten’ is listed as federally threatened under the Endangered Species Act and classified as a Species of Greatest Conservation Need in Oregon and California. Contemporary populations are small, and isolated, and threatened by habitat loss …
