Exploring Dissociation As A Facilitator Of Suicide Risk Using Virtual Reality, Nicole Caulfield

Master's Theses

Research shows that suicidal behavior is not a result of a single cause or single event, but instead is an interaction of facilitators. One potential facilitator that needs further exploration is dissociation. Dissociation has been consistently linked to suicidal behavior, and treatment for dissociative disorders seem to be associated with a reduction of suicidal ideation and suicide attempts. Prior theories have posited that dissociation increases the possibility of a suicidal act because of intensified disconnect from the body. However, these theories do not indicate whether dissociation is a facilitator of suicide risk by increasing suicidal ideation, attempt behaviors, and capability …

Hate Speech, Habitus, And Identity Signaling On 4chan’S Politically Incorrect Board, Jonathon Geiger

Master's Theses

Websites, such as 4chan, have provided a place for extremism and hate speech to flourish through anonymous discourse. One group that has been especially important to this growth has been the alt-right. The alt-right is a far-right white nationalist movement that is known for engaging in trolling, creating memes, and generating conspiracy theories. Past research has focused on the amounts of hate speech and characterizing content on the website. However, past studies have not looked at the experience of using the website through the combination of participant observation and content analysis. Here I show that the extensive use of hate …

Analysis Of Electroanatomic Mapping System Accuracy Using X-Ray Reconstruction Of Electrode Locations In A Porcine Animal Model, Hana Boudlali

Master's Theses

Fluoroscopy is considered the gold standard for locating catheters during cardiac electrophysiology (EP) procedures. However, fluoroscopy emits ionizing radiation which can lead to adverse health effects when exposed to in high doses (World Health Organization, 2016). Electroanatomic mapping (EAM) systems display the three-dimensional location of EP catheters and measure the local electrical activity of the heart. They can minimize a physician’s reliance on fluoroscopy and can help reduce radiation exposure during a case (Casella, 2011).

EAM systems are diagnostic medical devices that inform the placement of ablation therapy and must accurately locate catheters to be deemed safe. Test methods to …

Phantom Ocean, Real Impact: Natural Surf Sound Experiments Alter Foraging Activity And Habitat Use Across Taxa, Ryan N. Wardle

Understanding The Effects Of Long-Duration Spaceflight On Fracture Risk In The Human Femur Using Finite Element Analysis, Keyanna Brielle Henderson

Master's Theses

Long-duration spaceflight has been shown to have significant, lasting effects on the bone strength of astronauts and to contribute to age-related complications later in life. The microgravity environment of space causes a decrease in daily mechanical loading, which signals a state of disuse to bone cells. This affects the bone remodeling process, which is responsible for maintaining bone mass, causing an increase in damage and a decrease in density. This leads to bone fragility and decreases overall strength, posing a risk for fracture. However, there is little information pertaining to the timeline of bone loss and subsequent fracture risk.

This …

My Child’S Keeper: Child Vulnerability And Quality Of Life On Parental Stress And Grit, Abigail Armstrong

Master's Theses

There is a reciprocal relationship between parenting stress and child distress that has been well documented (e.g., Rechenberg, Grey & Sadler, 2017). These effects generalize to physical outcomes such that higher maternal depression has been associated with poorer child health-related quality of life (HRQOL; Jaser, Whittemore, Ambrosino, Lindemann, & Grey, 2008). In the same way that parental distress has been shown to affect the child, parental perceptions of child vulnerability in children with chronic illness has also been associated with negative outcomes, including child depressive symptoms (Mullins et al., 2004), increased health care use (Spurrier et al., 2000), and increased …

Development And Use Of An Environmental Dna Tool To Monitor Recovery Of The Critically Endangered Smalltooth Sawfish, Pristis Pectinata, In The Northwest Atlantic, Ryan N. Lehman

Master's Theses

The Critically Endangered Smalltooth Sawfish, Pristis pectinata, was once common in the tropical and subtropical waters of the Atlantic Ocean; however, following global declines in range and abundance over the past century, individuals were restricted to the waters of south and southwest Florida (SWFL) by about the 1980’s. Recently, public encounter reports have emerged in historically occupied habitats in United States waters, suggesting individuals are present in, or re-occupying, these areas, although the status of P. pectinata outside of SWFL is not currently well understood. Targeted environmental DNA (eDNA) surveys were chosen to assess the occurrence of P …

Effects Of Infection Of The Protist Parasite, Dermomycoides Sp., In Dusky Gopher Frog Tadpoles, Jaime Smith

Master's Theses

Infections of the protist parasite, Dermomycoides sp. are thought to have caused several years of low recruitment in the dusky gopher frog (Rana sevosa) populations. I evaluated the effects of density of the infective zoospores, host developmental stage, and tadpoles' ability to acquire resistance to Dermomycoides sp. on dusky gopher frog tadpoles. Tadpoles were exposed to zoospore densities of 0, 250, 500, and 750 zoospores/µL at Gosner stage 25, and we found no significant differences among treatments in tadpole mortality. In evaluating susceptibility by development stage, I exposed R. sevosa to 50 zoospores/µL as eggs, embryos, hatchlings, and …

Nutrition At Tipu: A Comparative Analysis Of Juvenile Health In Maya Populations, Sydnie A. Bianchi

The site of Tipu in west central Belize provided a foothold for Spanish missionaries in the 17^th century. The effects of contact on adults among the 550 burials recovered in the cemetery there have been well studied, but the children have received less attention. Therefore, this study examined juvenile health through four markers: Linear Enamel Hypoplasia (LEH), a non-specific marker of health disruptions; Porotic Hyperostosis (PH), an indicator of anemia; and Periostitis, an indicator of infection. Some 131 individuals were evaluated using criteria developed by Steckel, Sciulli, and Rose (2002). The results were compared to Late Classic Copán (Storey, …

Assessment Of Genetic Diversity In Largetooth Sawfish, Pristis Pristis, Populations Over The 20th Century, Ann Fearing

Master's Theses

The Critically Endangered Largetooth Sawfish, Pristis pristis, experienced global declines in range and abundance over the past century and Australia is now their last stronghold. This research aimed to understand whether these declines have been accompanied by a reduction in levels of genetic diversity. Using P. pristis tissue samples sourced from natural history specimens, three fragments (616-bp, 386-bp, 141-bp) in the mitochondrial DNA (mtDNA) control region were PCR-amplified. At each fragment, significant genetic structure was found in P. pristis overall (Φ_ST=0.946, N=9; 0.813, N=54; 0.771, N=99). The Indo-West Pacific and Atlantic/Eastern Pacific each harbor genetically distinct lineages of …

Microplastic Abundance, Distribution And Impacts On Sargassum-Associated Juvenile Fishes In The Gulf Of Mexico, Olivia Lestrade

Master's Theses

Microplastics are a concern in marine environments because they are highly durable, ubiquitous, and can be mistaken for food and ingested by small organisms. Pelagic Sargassum, an important habitat for larval and juvenile stages of many fish species, is found in large surface aggregations, and may provide complex structure in which microplastics become trapped. This could lead to greater risk of microplastic ingestion by fish early life stages associated with Sargassum habitats. To better understand the impacts of microplastics within Sargassum communities, this study examined 1) microplastic concentrations and ingestion by juvenile fishes associated with Sargassum; 2) the microbial …

The Relationship Between Company, Manager, Group, And Individual-Level Variables And Affective Commitment, Varavit Chinnapong

Master's Theses

Predicting employees' affective commitment to their organization continues to be of strong interest to researchers. Previous studies have examined the relationship between specific organizational levels (company, manager, group, individual) and affective commitment. However, there is a lack of research that has analyzed all four levels in one study. Therefore, the current study sought to evaluate the relationships between the four organizational levels and affective commitment. More specifically, the current study analyzed human resources practices as the company-level variables, transformational and transactional leadership as the manager-level variables, group cohesion as the group-level variable, and psychological safety at the individual level. The …

Using Kinetics And Small Angle X-Ray Scattering To Elucidate The Allosteric Regulation Of Sirt1, Christiane Cabreros

Master's Theses

SIRT1 is an NAD+ dependent deacetylase that has been implicated in many important cellular functions such as neurodegeneration and aging. SIRT1 has also been studied with resveratrol which was shown to modulate activity. While the mechanism of SIRT1 has been studied extensively, exact details are still not known, specifically the allosteric regulation by the N-terminal domain. We wanted to see if there is a correlation between the activity of SIRT1 and the distance of the N-terminal domain relative to the catalytic core. First we examined the kinetic parameters (kcat and KM) of SIRT1 with peptide substrates with and without resveratrol. …
