The Impact Of Vehicular Noise On The Effectiveness Of Acoustic Indices, Rebecca Ducay

Theses

Passive acoustic monitoring (PAM) is a valuable tool in wildlife research, offering non-invasive and cost-effective means to collect acoustic data. However, the processing of PAM recordings can be time-consuming, prompting the use of acoustic indices to expedite analysis. Acoustic indices are numerical values that characterize biological information in sound recordings based on an environment’s acoustic characteristics. While acoustic indices have been correlated with species richness across ecological contexts, their reliability diminishes in areas with heightened vehicular noise. However, it is unclear if index biases caused by vehicular noise are consistent across all traffic levels, and which acoustic indices are most …

Selenate-Mediated Impacts On Mercury Methylation By Pseudodesulfovibrio Mercurii With Dissolved And Nanoparticulate Mercuric Nitrate, Md Sayeduzzaman Sarker

Theses

Inorganic mercury (Hg) is converted to potential neurotoxic methylmercury (MeHg) by a natural process called Hg methylation. MeHg can be biomagnified in the food chain, thus the consumption of Hg-contaminated fish contributes to harmful human health issues. Selenium (Se) inhibits the Hg bioavailability to the methylating bacteria by forming mercuric selenide (HgSe). Pseudodesulfovibrio mercurii, a type of sulfate-reducing bacteria (SRB) cultures were grown in anaerobic environments using an estuarine sulfate lactate growth medium to evaluate the effects of Hg concentrations, bacterial growth phase, and sodium selenate in the Hg methylation process. Bacterial cultures contained two types of mercuric (II) nitrate, …

Block Copolymers And Chirality: Interplay Between Conformations And Structures, Natalie Buchanan

Theses

Block copolymers can exhibit chirality at three different length scales – molecular chirality at the residue scale, conformational chirality at the molecular scale, and structural chirality at the mesoscale from the self-assembly of thousands of molecules. Unique morphologies have been formed due to chirality transfer, a phenomenon where chirality at smaller length scales imparts chirality to larger length scales. However, chirality does not always transfer, with chiral blocks existing in an achiral phase due to chiral frustration. The thermodynamics of the effects of chirality on block copolymer self-assembly is not well understood. This work demonstrates that coarse-grained models can effectively …

Atoms And Leaves, Patty Tomanovich

Theses

Atoms and Leaves is a photographic project presented as windows into a utopia. The glass images display a potential time and place where the landscape, photography, and transness intertwine and grow from each other. Photography historically harms the landscape- requiring precious metals, releasing pollution into the atmosphere, and creating hazardous water waste. The traditional photographic canon erases the connection between queerness and ecology. Atoms and Leaves rethreads these connections, creating a world where photography collaborates with the landscape and takes on a transgender perspective by reshaping given material. The photographic printing process developed in this project was inspired by the …

An Egalitarian Approach To Explanations In Mental Disorders, Eli Driskill

Theses

Explanations of mental disorders come from a wide array of disciplines and epistemologies. How we conceive of and order these explanations has great importance for agency. Yet, psychiatry as a discipline has long suffered from the assumption that these explanations are multi-level. That is, some lower-level mechanism (i.e. neurobiology) constrains the information produced at a higher-level behavior. I argue that this approach is unsatisfying, and offer a new perspective: the egalitarian approach to mental disorders. The egalitarian model of mental disorders is non-hierarchical, dynamic, and cross-cultural. The paper begins by highlighting an inherent feature of psychiatry which I coin the …

Quantifying Landscape Change Using Different Spectrometers, Spectral Unmixing, And Uas Imagery, Bianca Cilento

Theses

Climate-driven land cover change and biodiversity loss are problems impacting food security, economic growth, human health, and cultural identity of arctic environments, such as Stordalen Mire, Abisko, Sweden (68.35’ N, 18.82’ E). The sensitive nature of these remote areas necessitates large-scale, less-invasive monitoring of environmental change via remote sensing combined with low-impact, cost-effective field validation of remote sensing products. This project assesses the accuracy and utility of two low-cost spectrometers, the Sherwin-Williams® ColorSnap® and the National Aeronautics and Space Administration (NASA) Science and Technology Education for Land/Life Assessment (STELLA-Q), in conjunction with ArcGIS and GoogleEarth Engine programs and aerial imagery …

Addicted To The Beloved? A Comparison Of Craving For And Attention To Beloved And Vape Stimuli, Caitlyn Harriman

Theses

People who are in love seem to be addicted to their beloved. People who are in love have attentional biases for the beloved and people who are addicted have attentional biases for the substance they are using. This raises the question of how similar craving and attention are for the beloved and an addictive substance. However, there are no studies that directly compared craving and attention to the beloved and addictive stimuli. The aims of the current research were to directly compare subjective emotional experiences, sustained motivated attention, and early automatic attention for the beloved and vape stimuli, in people …

On Learning Your Gender: A Comprehensive View, Audra M. Hazelwood

Theses

This essay provides a metaphysical and epistemological account of gender. The metaphysics involves a ‘non-reductionist view of gender’, which is to say that gender cannot be reduced to a single factor. On this view gender begins with one’s innate gender inclinations (in the vein of Julia Serano). These inclinations pick out a specific range of gender possibilities from the gender spectrum that apply to a person. At the same time we live in communities and cultures with certain gender norms. This is where epistemology comes into play since our gender inclinations are filtered through gender norms and some people are …

Towards Erasing The Distinction Between The Computational And Syntactic Accounts Of Scientific Theories, Timothy Luft

Theses

One of the main goals of philosophy of science is to give a proper account of scientific theories and their structure. One way that accounts of the structure of scientific theories can be distinguished is by the mathematical or logical structures that they involve. For instance, syntactic accounts of scientific theories hold that theories are axioms in a logical framework, whereas semantic accounts are more liberal in the range of mathematical and logical structures they take as pertinent to the structure of scientific theories. Paul Thagard (1988) offers a computational account of scientific theories, which holds that theories are complex …

Between Fodor And Sellars -- A Middle Ground For Language-Like Neural Representations, Hanzhe Dong

Theses

The recent resurgence of the language of thought (LOT) hypothesis has drawn much attention. The history of philosophy and cognitive science has provided us with various versions of LOT. From Sellars to Fodor, theorists have offered us considerations on the vehicles, content, and functions of such a representation format. However, it’s been more than 50 years since Fodor’s publication on LOT (1975), and the resurgence suggests that we need a modern iteration of LOT to fit with recent developments in the study on cognition. Therefore, in this paper, I argue that we need a middle ground between Fodor and Sellars’s …

The Interaction Of Sodium Fluoride And Sodium Selenate On The Developmental Toxicity To Xenopus Laevis And Ambystoma Maculatum Embryos, Shelby Wolfram

Theses

Amphibians play critical roles in the environment's wellness. Fluoride (F) is a widely existing environmental pollutant. It is commonly known for being added to drinking water and as a topical dose on teeth. Selenium (Se) can be found in organic and inorganic forms in nature. Many different fertilizers, pesticides, insecticides, and fungicides contain sodium selenate in them. The range selenium has between deficiency and toxicity is narrow, meaning excess exposure could cause various adverse effects in aquatic organisms. Xenopus laevis is a standard model for developmental toxicity due to being minimal maintenance, cost efficient, and having transparent embryos. Xenopus makes …

Exploring The Potential Pathogenicity Of A Type 2 Diabetes Mellitus Associated Insr Missense Variant Of Uncertain Significance Through Daf-2 In The Caenorhabditis Elegans Model, Brittany White

Theses

Type 2 diabetes mellitus (T2DM) is hallmarked by insulin resistance, with the INSR gene identified as a key player in this condition in humans. This gene is known to harbor genetic variants with a wide range of clinical significance from pathogenic to variants of uncertain significance (VUS) to benign. This project investigates a VUS associated with T2DM identified through ClinVar. A gene mutational analysis, predictive amino acid substitution analysis, and protein modeling predict INSR c.1628C>T (p. Thr543Met) to be likely pathogenic or damaging. PolyPhen-2 predicts this variant to be probably damaging (HumDiv score of 1.000).

Pollution caused by heavy metals (HMs) is a major environmental concern worldwide. Human actions, agriculture practices and industrial activities can cause the release of HMs into the environment. Soil contamination with HMs may have negative effects on crops, thus disrupting the food chain and posing risks to human health. Lead (Pb) is a common pollutant found in the soil when at high concentrations. Conventional land remediation techniques depending on chemical and mechanical methods are quite expensive and would lead to long-term deterioration of the ecosystems, while phytoremediation can serve as an alternative, eco-friendly approach to restore the lands for agricultural …

Expression Of Human Arginine Vasopressin In Arabidopsis Thaliana And Assessment Of Abiotic Stress Tolerance, Maitha Salem Aldarmaki

Theses

Human Arginine Vasopressin (HsAVP) is a nona-peptide that acts as an antidiuretic hormone. In human AVP regulates water permeability through the regulation of the water channel, aquaporin 2. The process begins with the binding of vasopressin to V2 receptor which activates cAMP-dependent protein kinase A (PKA). PKA phosphorylates aquaporin-2 at Ser256 and allows the aquaporin-2-containing vesicle to fuse with the apical membrane which increases water permeability. The present study describes the functional analysis of the codon-optimized HsAVP overexpressed in Arabidopsis thaliana. The main objective of the study is to assess if HsAVP affects drought and salinity stress …

Novel Methods For Modeling And Treating Biofilm Infections, Emily Lazarus

Theses

Biofilms are responsible for the development of chronic infections, which are 10-1000 times more resistant to antimicrobial agents than two-dimensional (2D) planktonic culture. Traditionally, 2D planktonic cultures are used to study efficacy of antimicrobial treatments but 2D cultures have several shortcomings such as increased sensitivity to treatments, lack of complexity of the three-dimensional (3D) environment, limited host defense mechanisms, and lack the structural thickness of natural biofilms. Biofilm-related infections play a critical role in the delayed healing process of chronic skin wounds, and while treatments for chronic skin wounds exist, including negative pressure wound healing (NPWT), biofilm infections still prevail. …

Detailing The Effects Of Cannabidiol On Exosome Release In Ewing’S Sarcoma, Bennett Hasley

Theses

Ewing’s sarcoma (ES) is a highly aggressive pediatric cancer found within bone that carries a low five-year survival rate within its patients. This is due, in part, to the cancer’s high malignancy properties as well as the development of resistance to the chemotherapies used to combat this cancer. This project aims to determine if cannabidiol (CBD) has an effect on either exosome release or the protein, signal transducer and activator of transcription 3 (STAT3) within ES cells. Exosomes are vesicles that can carry proteins and other signaling molecules which are released by the cell and allow for cell-to-cell communication. Within …

Menossance ™: Post-Maternity Strategies, Elizabeth Pursell

Theses

Inside the private lives of middle-aged women, significant suffering unfolds in silence. The universal “change” is shrouded in shame. The obstacles particular to women during midlife include physical, emotional, financial, professional, familial, and societal. Many suffer through the indignities of menopause while adjusting to an “empty-nest” (Gullette, 2002, p.554). Droves of middle-aged women are also part of the so-called “Sandwich Generation” (Hong, 2002, p. 358). They are sandwiched between the responsibilities of their children and their elders, all while tenuously balancing careers and menopause. As described in Umma’s Table, “The sandwichgeneration [is] impossibly caught between multigenerational responsibilities, navigating labyrinthine sociomedical …
