Imaging Ductal Carcinoma Using A Hyperspectral Imaging System, Yasser M. Khouj
Graduate Theses, Dissertations, and Problem Reports (ETD)
Hyperspectral Imaging (HSI) is a non-invasive optical imaging modality that shows the potential to aid pathologists in breast cancer diagnoses cases. In this study, breast cancer tissues from different patients were imaged by a hyperspectral system to detect spectral differences between normal and breast cancer tissues, as well as early and late stages of breast cancer. If the spectral differences in these tissue types can be measured, automated systems can be developed to help the pathologist identify suspect biopsy samples, which will improve sample throughput and assist in making critical treatment decisions. Tissue samples from ten different patients were provided …
Effects Of Anti-Viral Acute Phase Response On Hippocampal Glutamate Regulation, Holly C. Hunsberger
Effects Of Anti-Viral Acute Phase Response On Hippocampal Glutamate Regulation, Holly C. Hunsberger
Graduate Theses, Dissertations, and Problem Reports (ETD)
A large body of clinical evidence suggests that viral infections in the periphery can exacerbate neurodegenerative conditions such as Alzheimer's disease, Huntington's, disease, Parkinson's disease, multiple sclerosis, and seizures. The underlying mechanisms of these conditions involve the activation of the acute phase response (APR), part of the innate immune system, which recognizes viral molecular patterns. As neighboring cells become infected, inflammatory mediators are released into the bloodstream and relayed to the central nervous system where they produce a "mirror" inflammatory response. To induce the APR, polyinosinic-polycytidylic acid (PIC), a viral mimetic, is commonly used. PIC produces a robust and transient …
Board Out Of Your Mind: Mapping Players' Mental Models Of Game Systems And Potentials For Systems-Thinking Instruction, Joe A. Wasserman
Board Out Of Your Mind: Mapping Players' Mental Models Of Game Systems And Potentials For Systems-Thinking Instruction, Joe A. Wasserman
Graduate Theses, Dissertations, and Problem Reports (ETD)
Despite evidence that game-based instruction is effective, and suggestive evidence that they are specifically effective for teaching systems thinking---the ability to think about complex systems---the mechanisms behind this learning are not well understood. One promising perspective on game-based learning is rooted in the development of mental models of game systems. Mental models are cognitive representations of the perceived entities and relationships between entities in a system. This study explores the entities and entity relationships in novice players' mental models of an analog game. Grounded, interpretive analysis of mental models externalized through cognitive mapping identified five categories of entities: formal game …

Measuring And Changing Preschool Children's Stuttering Attitudes, Mary E. Weidner
Graduate Theses, Dissertations, and Problem Reports (ETD)
Background: Negative or uninformed stuttering attitudes proliferate among the general public, and burgeoning research has shown that such attitudes might emerge as early as the preschool years. Despite decades of research on the topic, much remains unknown about the origin of stuttering attitudes and the factors that bear on their development. Moreover, conclusive recommendations to improve attitudes toward stuttering have yet to be advanced.;Purpose: This study sought (a) to objectively measure stuttering attitudes among preschool children, (b) to examine predictive factors that might account for those attitudes, and (c) to determine the effect of a new educational program on improving …
Perceptions Of The Bereaved: Attributions, Emotions, And Prosocial Behavior, Christine Weir
Perceptions Of The Bereaved: Attributions, Emotions, And Prosocial Behavior, Christine Weir
Graduate Theses, Dissertations, and Problem Reports (ETD)
This study explored a new application of Weiner's Attributional Model to suicide bereavement, and how friends and coworkers respond in their emotions and prosocial behavior. This is a comprehensive theoretical model addressing how people respond to negative events occurring in the lives of others. Its premise is the influence of attributions on the behavior, affect, and cognitive processes of the helper. The model's broad underpinnings are that attributions for challenging behavior can in turn produce a crucial effect on helping behavior. Previous qualitative research on suicide survivors has suggested that attitudes and beliefs towards suicide survivors by those in the …
Multidimensional Coherent Spectroscopy Of Gaas Excitons And Quantum Microcavity Polaritons, Brian L. Wilmer
Multidimensional Coherent Spectroscopy Of Gaas Excitons And Quantum Microcavity Polaritons, Brian L. Wilmer
Graduate Theses, Dissertations, and Problem Reports (ETD)
Light-matter interactions associated with excitons and exciton related complexes are explored in bulk GaAs and semiconductor microcavities using multidimensional coherent spectroscopy (MDCS). This approach provides rich spectra determining quantum excitation pathways, structural influences on the excitons, and coherence times.;Polarization, excitation density, and temperature-dependent MDCS is performed on excitons in strained bulk GaAs layers, probing the coherent response for differing amounts of strain. Biaxial tensile strain lifts the degeneracy of heavy-hole and light-hole valence states, leading to an observed splitting of the associated excitons at low temperature. Increasing the strain increases the magnitude of the heavy-/light- hole exciton peak splitting, induces …
Climate Change, Capitalism, And Citizen Science: Developing A Dialectical Framework For Examining Volunteer Participation In Climate Change Research, Joshua A. Wixom
Climate Change, Capitalism, And Citizen Science: Developing A Dialectical Framework For Examining Volunteer Participation In Climate Change Research, Joshua A. Wixom
Graduate Theses, Dissertations, and Problem Reports (ETD)
This dissertation discusses the complex social relations that link citizen science, scientific literacy, and the dissemination of information to the public. Scientific information is not produced in value-neutral settings by people removed from their social context. Instead, science is a social pursuit and the scientist's social context is embedded in the knowledge produced. Additionally, the dissemination of this information via numerous media outlets is filtered through institutional lenses and subject to journalistic norms. As a result, the general public must be able to recognize the inherent biases in this information. Yet, the rates of scientific literacy in the U.S. are …

Using A Duration-Based Schedule Performance Index To Monitor The Performance Of Projects Including Estimating The Final Cost, Nooshin Yousefi
Graduate Theses, Dissertations, and Problem Reports (ETD)
One of the main concerns of project managers is monitoring the schedule performance of construction projects. A project manager needs tools to not only understand the status of project schedule performance, but also to find the causes of delays and the corresponding corrective actions. Hence, discovering time deviations from the project plan provides more reliable project schedule control. Applying statistical quality control charts on the project schedule performance index is suggested in this study. The use of quality control charts in this research monitors the process plan and provides first alarms for applying changes by detecting the time deviations over …

A Description Of The Sound System Of Misiones Mbya, Matias N. De Paula
Graduate Theses, Dissertations, and Problem Reports (ETD)
Misiones Mbya is an indigenous language of South America spoken by the Mbya people in the Province of Misiones, Argentina. Although there are several studies in the literature about the Brazilian variety of this language, the linguistic information available about Misiones Mbya is extremely scarce. In this thesis I present a segmental analysis of the language (individual vowels and consonants) and a prosodic analysis of nasal harmony based on field data collected in three different communities in Misiones. The segmental analysis shows that this variety is very similar to the Brazilian variety of the language with only a few exceptions. …

Beyond The What And How: Why Parents Want To Know About Their Adolescents' Lives., Elizabeth Yale Babskie
Graduate Theses, Dissertations, and Problem Reports (ETD)
As adolescents spend more time away from home and increasingly engage in unsupervised activities, parents are challenged with allowing their children more responsibility while still promoting positive youth development (Smetana, Campione-Barr, & Metzger, 2006). Extant research shows that parents continue to play an important roll in facilitating positive adolescent development through their knowledge of what their adolescent children are doing and whom they are with when away from home or school (Racz & McMahon, 2011). Recent research has focused on understanding the sources of parents’ knowledge and has identified both parentdriven (rules, solicitation, indirect, covert) and adolescent-driven (disclosure, secrecy, concealment) …

Controls On Ecosystem Nitrogen (N) Status And Carbon (C) Balance In Red Spruce Forests Located In A Region Of Historically High Atmospheric N Deposition., Kenneth R. Smith
Graduate Theses, Dissertations, and Problem Reports (ETD)
Atmospheric deposition of reactive nitrogen (N) can have a strong influence on patterns of carbon (C) and N cycling in forest ecosystems. High-elevation red spruce (Picea rubens Sarg.) forests in the central Appalachian Mountains have historically been among the most sensitive ecosystems to the negative effects of N deposition. I examined the primary environmental factors that influence 1) N status, 2) belowground C balance, and 3) red spruce aboveground growth in seven high-elevation study sites that are located in an area where N deposition has been historically moderate to high. I established the seven sites in 2011 along a transect …

Physicochemical Modulation Of Huntingtin Aggregation On Lipid Membranes: Implications For Huntington's Disease, Maxmore Chaibva
Graduate Theses, Dissertations, and Problem Reports (ETD)
Huntington disease is a genetic, neurodegenerative disease caused by an expanded polyglutamine (polyQ) in the first exon of the huntingtin (htt) protein, facilitating its aggregation, leading to the formation of a diverse population of potentially toxic aggregate species, such as oligomers, fibrils, and annular aggregates. Htt interacts with a variety of membranous structures within the cell, and the first seventeen amino acids (Nt17) of htt directly flanking the polyQ domain is an amphipathic alpha-helix (AH) lipid-binding domain. AHs are also known to detect membrane curvature. Nt17 also promotes diverse aggregate species of htt and undergoes a number of posttranslational modifications …

Ecological Effects Of Forest Canopy Disturbance On The Understory Plant, American Ginseng (Panax Quinquefolius L.), Jennifer L. Chandler
Ecological Effects Of Forest Canopy Disturbance On The Understory Plant, American Ginseng (Panax Quinquefolius L.), Jennifer L. Chandler
Graduate Theses, Dissertations, and Problem Reports (ETD)
Historical accounts suggest that American ginseng was once far more abundant than it is today, and extensive changes in forest canopy structure and ginseng habitat caused by clearcut timber harvest occurred coincidentally to the precipitous decline in abundance. The presence of natural American ginseng populations after widespread clearcuts suggests that ginseng can survive under sparse canopies, and the presence of ginseng in the second growth forests common today suggest that ginseng can survive under dense canopies. However, performance may not be optimal at either end of the disturbance spectrum, and the net effect of direct and indirect anthropogenic canopy disturbances …

Endocannabinoid Modulation Of Secretory And Inflammatory Causes Of Gastric Pathology, Molly S. Crowe
Endocannabinoid Modulation Of Secretory And Inflammatory Causes Of Gastric Pathology, Molly S. Crowe
Graduate Theses, Dissertations, and Problem Reports (ETD)
Non-steroidal anti-inflammatory drugs (NSAIDs) are common analgesic drugs that also cause well-known, negative gastrointestinal (GI) side effects. The specific physiological mechanism(s) of NSAID-induced GI damage are unknown, and are likely due to multiple causes. The most studied components include: increased gastric acid secretions, inflammation of the gastric epithelium, and increased gastric motility. Currently, proton pump inhibitor (PPI) antacids are used by chronic NSAID users, with the expectation that decreasing gastric acid output will reduce gastric epithelial irritation. However, PPIs are associated with side effects like infection, gastric polyps, and dementia. Therefore, new gastroprotective treatments that prevent NSAID-induced gastropathy are needed. …

Applying Psychological Reactance Theory To Communication Between Adult Child Caregivers And Their Older Adult Parents, Hannah Ball
Applying Psychological Reactance Theory To Communication Between Adult Child Caregivers And Their Older Adult Parents, Hannah Ball
Graduate Theses, Dissertations, and Problem Reports (ETD)
Given the rapid growth of the older adult population in the US and the number of adult children providing informal care to their older adult parents, there is a need for a better understanding of how communication can be used to negotiate the tension between dependence and autonomy in these caregiving relationships (Egbert, 2014; Morgan & Hummert, 2000). Guided by psychological reactance theory (Brehm, 1966; Brehm & Brehm, 1981), which posits that individuals value their autonomy and are motivated to restore it when they perceive that it is being threatened, the purpose of this dissertation was twofold: (a) to explore …
Safe Semi-Supervised Learning With Sparse Graphs, Prithish Banerjee
Safe Semi-Supervised Learning With Sparse Graphs, Prithish Banerjee
Graduate Theses, Dissertations, and Problem Reports (ETD)
There has been substantial interest from both computer science and statistics in developing methods for graph-based semi-supervised learning. The attraction to the area involves several challenging applications brought forth from academia and industry where little data are available with training responses while lots of data are available overall. Ample evidence has demonstrated the value of several of these methods on real data applications, but it should be kept in mind that they heavily rely on some smoothness assumptions. The general frame- work for graph-based semi-supervised learning is to optimize a smooth function over the nodes of the proximity graph constructed …
Perceptions Of Urban Forestry Employers, Andrew Benjamin
Perceptions Of Urban Forestry Employers, Andrew Benjamin
Graduate Theses, Dissertations, and Problem Reports (ETD)
Urban forestry is still a relatively new area of science and is still trying to establish itself as a legitimate scientific field and profession. Often urban forestry and arboriculture are conflated, and urban forestry has yet to achieve much of what arboriculture has in terms of recognition its and establishment. Landscape architects, traditional foresters, environmental scientists, horticulturalists all may find themselves in positions that can be classified in the urban forestry profession, which shows this lack of a standard definition for what is an urban forester. While there are many significant, potential benefits to a properly managed urban forest resource …
