The Influence Of Training Procedures On Generalization Performance In Scent-Detection Rats, Erin Watkins

Dissertations

The global illicit trade in tobacco products leads to an overall increase in the availability of tobacco, and this increase in tobacco availability and consumption undermines effective health, safety, and taxation policies in place to protect current and future populations. Dogs working at ports and customs have been trained to detect tobacco products and research has shown rats can detect tobacco-soaked filters (Mahoney et al., 2014). Cigarette smoking is the most common form of tobacco use, and cigarettes are the most commonly trafficked product in the illicit tobacco trade. In the current study, rats were trained to respond to filter …

Artificial Immune Systems: Applications, Multi-Class Classification, Optimizations, And Analysis, Brian Haroldo Schmidt

Dissertations

The focus of this research is the application of the Artificial Immune System (AIS) paradigm to a new research area along with the modifications necessary to adapt it to a new problem. In the past 10 years, there has been much research into the use of various Machine Learning (ML) algorithms in Network Flow Traffic Classification. AIS algorithms have thus far not been applied to this problem. Because AIS algorithms have been used extensively for Network Intrusion Detection applications, which is a similar area of research, the motivation to extend them to the network flow classification problem is clear.

Subgroup Analysis And Growth Curve Models For Longitudinal Data, Nichole Andrews

Dissertations

In clinical trials and biomedical studies, treatments are compared to determine which one is effective against illness. Growth curve analysis can be beneficial in longitudinal biomedical studies, as we can evaluate the treatment effect on the response over time. The generalized growth curve model using polynomial regression is proposed for longitudinal data. An optimal degree for the polynomial is obtained using the BIQIF, an adaptation of the Bayesian information criterion. Quadratic inference functions are used to estimate the parameters of the model, which takes into account the fact that repeated measurements from the same subject are more likely to be …

Middle School Student And Teacher Perceptions About The Effectiveness Of The Technology Integration In The Classroom, David R. Irby

Dissertations

Technology in schools is not a new phenomenon, however, whether technology integration is successful or not is up for debate. Critics of technology in the classroom write about failed attempts to integrate technology into the classroom in a meaningful way. Research indicates that we still have teachers using technology in ways that may not be much different than traditional teaching practices.

The literature describes varying levels of technology usage in the classroom. Some researchers describe technology as overrated and not fulfilling the promise to improve the teaching and learning experience. Other research describes unique uses of technology that promote engaging …

In Vivo Characterization Of The Drosophila Mrna 3’-End Processing Core Cleavage Complex: Poly(A) Mrna & Histone Mrna 3’-End Processing, Daniel Michalski

Dissertations

A core cleavage complex (CCC) consisting of CPSF73, CPSF100 and Symplekin is required for co-transcriptional 3’ end processing of all metazoan pre-mRNAs, yet little is known about the in vivo molecular interactions within this complex. The CCC is a component of two distinct complexes, the cleavage/polyadenylation complex and the complex that processes non-polyadenylated histone pre-mRNAs. RNAi-depletion of CCC factors in Drosophila culture cells causes reduction of CCC processing activity on histone mRNAs, resulting in read through transcription. In contrast, RNAi-depletion of factors only required for histone mRNA processing allows use of downstream cryptic polyadenylation signals to produce polyadenylated histone mRNAs. …

Exploring Whites' Recognition Of Racial Microaggressions Through An Existential Lens, Ashley Gold Parker

Dissertations

Substantive evidence demonstrates that targets of racial discrimination (i.e., people of color) are acutely aware of racial microaggressions when they occur. Far less research has explored the interpretive experiences of perpetrators and bystanders of race-related prejudice and discrimination, individuals who are typically White. The current study sought to identify personal and situational factors that affect Whites’ recognition of racial microaggressions. The sample consisted of self-identified exclusively White/Caucasian adults (N=210) who completed questionnaires exploring Belief in a Just World (BJW), Social Dominance Orientation (SDO), and three facets of Ethnocultural Empathy (Awareness, Perspective-Taking, and Empathic Action). Participants were randomly assigned …

Assessment Of A Hand Exoskeleton On Proximal And Distal Training In Virtual Environments For Robot Mediated Upper Extremity Rehabilitation, Kevin Abbruzzese

Dissertations

Stroke is the leading cause of disability in the United States with approximately 800,000 cases per year. This cerebral vascular accident results in neurological impairments that reduce limb function and limit the daily independence of the individual. Evidence suggests that therapeutic interventions with repetitive motor training can aid in functional recovery of the paretic limb. Robotic rehabilitation may present an exercise intervention that can improve training and induce motor plasticity in individuals with stroke. An active (motorized) hand exoskeleton that provides support for wrist flexion/extension, abduction/adduction, pronation/supination, and finger pinch is integrated with a pre-existing 3-Degree of Freedom (DOF) haptic …

Healthcare Use Self-Efficacy In Adults Who Are Homeless, Jared Ian Israel

Dissertations

The physical and mental health care needs of homeless adults are extensive. However, these needs regularly go unmet. Healthcare use behavior is complex and involves a range of obstacles. As such, self-efficacy, an individual’s belief in his or her ability to perform a given behavior, appears to be a relevant factor in healthcare use. While current theory supports this notion and research has confirmed the role of self-efficacy in health behavior generally, a validated measure of healthcare use self-efficacy has not previously existed. The aim of this study was to develop and validate the Healthcare Use Self-Efficacy List (HUSEL) in …

Role Of The Interleukin-22 And Stat3 Signaling Pathway In Gut Barrier Maintenance Following Intoxication And Burn Injury, Adam M. Hammer

Dissertations

More than half of patients admitted to burn centers for treatment have measurable alcohol levels in their blood. Intoxication that precedes a traumatic burn injury leads to worsened patient outcomes, including higher rates of infection and sepsis. The intestines harbor the largest concentration of bacteria in the human host. Any disruption of the intestinal barrier as a result of intoxication and burn injury could contribute to infection and/or sepsis from gut-derived microbes. Previous work has demonstrated that the intestinal barrier becomes leaky, and that administration of interleukin-22 (IL-22) significantly reduces gut barrier leakiness following alcohol and burn injury. However, the …

Endocytic Vesicle Rupture In The Pathogenesis And Propagation Of Neurodegenerative Proteinopathies, William P. Flavin

Dissertations

Numerous pathological amyloid proteins spread from cell-to-cell during neurodegenerative disease, facilitating the propagation of cellular pathology and disease progression. Understanding the mechanism by which disease-associated amyloid protein assemblies enter target cells and induce cellular dysfunction is therefore key to understanding the progressive nature of such neurodegenerative proteinopathies. In this study, we utilized an imaging-based assay to monitor the ability of disease-associated amyloid assemblies to induce the rupture of intracellular vesicles following endocytosis, as well as to elucidate the cellular consequences of this damaging mechanism of invasion. We observed that the ability to induce vesicle rupture is a conserved feature of …
