Thermally Rearranging Polyimide Networks For High-Temperature Applications, William Guzman

Dissertations

High-performance polymers can retain functional properties when exposed to long-term or short-term durations of harsh conditions, such as mechanical action, at elevated temperatures (>177 °C). A mixture of intramolecular and intermolecular forces of and between polymer chains provide excellent property retention at elevated temperatures. Specifically, the highly aromatic nature of high-performance polymer backbones provides outstanding thermal stability, which is typically attributed to π-π stacking. However, the interrelationship between thermal stability and high aromaticity creates a challenging structure-processing relationship paradigm, which causes poor polymer processability in most high-performance polymers. Herein, it was demonstrated that rationally designing a crosslinking phenylethynyl imide …

The "Othering" Of America: How The Strategic Use Of Crisis And Ressentiment Succeeded In The Trump Era, Laura J. Franklin

Dissertations

The establishment of a crisis theme through public rhetoric often triggers widespread attention, resulting in public concern and media coverage of an issue that could potentially be overblown or deceptive. In right-wing political discourse, this crisis warning is typically delivered by a White male leader with ready access to the powerful news media. An “us versus them” theme often occurs. Within this mode of a hegemonic exclusion, a culture of immigrants or an American minority are often depicted, perhaps aggressively, as a threat: A threat used to motivate, enrage and create the frustrations inherent in ressentiment. This dissertation explores the …

Mating Burrows In The Fiddler Crab Leptuca Pugilator: How A Key Resource Is Contested, Constructed, And Shared, Zachary Michael Lane

Dissertations

The Atlantic sand fiddler crab, Leptuca pugilator, is found on sandy, vegetated beach across a large portion of the United States’ Atlantic and Gulf of Mexico coasts and is iconic in regions where dense populations of the species occur for its charismatic courtship, competitive, and foraging behaviors. The social dynamics of the species are complex. Reproductively active males maintain mating territories in the dangerous heat of the intertidal zone, away from their food source at the water’s edge, where they inhabit specialized mating burrows. These mating burrows are essential to successful female reproductive success, and when it is time …

The Mobility Of Long-Lived Radioisotopes And Their Burial In The Marine Environment, Neil Redmond

Dissertations

Marine sediments record chemical signals that reflect past environmental conditions. It is important to establish how these signals are created and whether they may be altered over time so that they can be useful for reconstructing ocean history. Measurements of uranium isotopes are used as a novel proxy for sedimentary diagenetic processes (Chapter 2). Because ²³⁴U can be ejected from mineral lattice during the decay of ²³⁸U, it creates a pool of U in porewater that is potentially mobilized and then deposited elsewhere in the core. We found that alpha-recoiled ²³⁴U is sensitive to differences in sediment …

​​The Effects Of Viewpoint, Motion, And Affordance Priming On Perceptual Learning Of Feelies​, Catherine Dowell

Dissertations

According to Gibson and Gibson (1955) perceptual learning is a process of developing the skill to differentiate previously undifferentiated but available information. The initial investigations focused on object identification, lacking a behaviorally relevant functional task. In the current study participants learned to differentiate between novel objects (feelies). To test the role of visual exploration objects were viewed from either a side or a top view and were displayed as either static pictures or rotating about a vertical axis. In Experiment 1 a simple object discrimination task was used. Perfect accuracy was achieved sooner in static conditions compared to motion conditions …

A Network Analysis Examining Dissociation And Suicide Risk In Military Veterans And Non-Veterans, Nicole Caulfield

Dissertations

Higher rates of dissociation are related to more severe psychopathology, psychiatric comorbidity, and poorer response to treatment, yet there is limited research examining dissociation as a transdiagnostic factor. In particular, examining dissociation in a Veteran sample is vital, as Veterans have been shown to have higher trauma exposure and dissociation rates than non-Veterans. Dissociation has been linked to several adverse outcomes related to Veterans, particularly suicide, as dissociation may increase the possibility of a suicidal act because of intensified disconnect from the body. However, research examining the relationship between dissociation, suicide, and additional related factors has been limited, given the …

Meta-Analysis Of Effective Instruction Delivery, Halley Blanchard

Dissertations

Effective instruction delivery (EID) is a combination of antecedent and consequent strategies used to increase child compliance with adult instructions. The current meta-analysis sought to evaluate the effects of EID as an independent and combined treatment component across studies, as well as evaluate the reported treatment acceptability across studies. Additionally, moderator analyses were conducted to determine the impact of interventionist type (i.e., parent or teacher), implementation setting, child age, and child diagnosis on the effects of EID on child compliance. The analysis generated large effect sizes for EID across studies and high levels of treatment acceptability. The effects of EID …
