Does Convenience Come With A Price? The Impact Of Remote Testimony On Expert Credibility And Decision-Making, Ashley Jones

Dissertations

Legal cases involving expert testimony, especially by forensic mental health professionals, is increasingly relying on remote testimony to reduce associated costs and increase availability of such services. There is some evidence to show that expert testimony delivered via videoconference (VC) is comparable to expert testimony delivered in person; however, the most compelling evidence for this claim is unpublished. Other evidence across disciplines showed relative comparability between VC and in-person modalities across various types of outcomes. Based on both unpublished and published findings, this study tested the hypothesis that minimal differences in measures of expert credibility, efficacy, and weight assigned to …

Social Spaces, Places, And Substance Use In Shaping Queer Identities, Alessandra Milagros Early

Dissertations

Research has suggested that queer people may be more likely than their cisgender heterosexual counterparts to use substances. Largely, these higher rates are commonly explained through frameworks of victimization or (ab)use that render substance use as a form of coping or inherently problematic. While some queer people do use substances to cope, the social spaces, places, and contexts in which use often occurs are often obscured or ignored. More recently, contemporary queer criminologists have explored queer substance use and have considered how it is intimately linked to social space, place, identity formation, and community building. This dissertation draws from queer …

A Grounded Theory Study Of The Grief Process In Women Who Experienced Perinatal Loss Prior To 1980, Tina L. Saunders

Dissertations

Approximately one million women suffer from perinatal loss (PL) in the United States annually. Societal and provider knowledge and attitudes about the psychological effects of PL and the need for care and support have improved significantly since the 1980s. Anecdotal evidence indicates that experiencing PL still affects women decades later; however, its impact on their grief process and long-lasting effects has not been researched. These narratives are vital to informing support and care. The purpose of this study was to develop a theoretical framework describing grief processes and long-lasting effects on women experiencing PL before 1980.

Gold(I)-Hydroarylation In Polymer Modification – Alkynes And Alkenes With Unexpected Reactivity, Samuel B. Hunt

Dissertations

Polymer modification is crucial for developing new properties and materials from recalcitrant waste polymers. Synthetically, polymers possess a chemical inertness that renders their functionalization challenging. Specifically, the omnipresence of C–H bonds in all commercial polymers endows their chemical resistance. Thus, developments in C–H activation chemistry are crucial to polymer diversification processes and allow for fundamental insight into the role of material processing conditions on novel chemical reactions. Au(I)-chemistry has recently come to the fore owing to a unique chemical reactivity nonexistent with other transition metals. The alkynophilicity of Au(I), in tandem with their insensitivity to common polymer processing conditions (air, …

Sit Less, Move More: A National Study Of Physical-Activity Behavior And Cancer, Stella O. Nwogugu

Dissertations

Physical activity is associated with lower risks of cancer, the second leading cause of death among Americans. Yet, sedentary behavior is the prevailing lifestyle for about 80% of American adults. Additionally, cancer survivors remain significantly inactive, even though physical activity has been shown to decrease risk of cancer and cancer recurrence, improve tolerance of cancer therapy, and reduce mortality. This research explores the relative impact of personal agency, social support, and key demographic variables on physical-activity behavior for a national sample of adults as well as how these relationships differ for cancer survivors and their counterparts.

Large-Scale And Meso-Scale Ion Dynamics Of The Near-Earth Space Environment, Matthew Cooper

Dissertations

The mechanisms whereby low energy (order of lOs to 100s of eV) solar wind and ionosphere sourced particles are accelerated to high energy (order of 10s to 100s keV) in the Earth's magnetosphere are a trending research topic due to impacts on radiation belt populations, coupling to the high-latitude ionosphere, and energy budgets for collision-less plasma in dipole fields. Ultra-low frequency (ULF, order of 1-100 mHz) Alfven waves observed in the nightside inner magnetosphere during geomagnetic activity are one such acceleration mechanism. Several source processes for these waves, including the micro-scale drift-mirror mode, have been previously suggested but observational evidence …

Multi-Physics Numerical Simulation Of Corrosion And Service Life Evaluation Of Novel Reinforced Concrete Systems, Jin Fan

Dissertations

Durability challenges of reinforced concrete materials can shorten the service life and increase the carbon footprint of civil infrastructure systems. Novel alternative materials, such as high-performance fiber reinforced cementitious composites (HPFRCCs) and recycled aggregate concrete (RAC), offer an alternative to tradi-tional concrete materials by increasing the service life of infrastructure or reducing raw material consumption, thereby reducing the life-cycle carbon footprint. Due, in part, to a lack of robust numerical tools, predicting the durability response of these emerging cementitious materials has been insufficiently addressed. A time-dependent multi-physics modeling framework is proposed and adopted to investigate the chloride induced deterioration mechanisms …
