The Effect Of Extended Saltwater Absorption And Uv Cure On The Compressive Properties Of Msla 3d-Printed Photopolymer Resin Samples With Printing Variations, Suzanne Dixon

Theses and Dissertations

Liquid Crystal Display (LCD) 3D printers, also known as Masked Stereolithography Apparatus (MSLA), is a type of vat polymerization printing technique that cures liquid resin into a solid object. This technique is relatively new. Consequently, there is a shortage of detailed research on the impact of long-term environmental exposure on the MSLA-printed materials. The research within this document informs engineers and scientists of resin compressive properties after extended exposure to saltwater and ultraviolet (UV) light. Saltwater absorption of the material was analyzed at atmospheric pressure, 30-psi, 60-psi, and 90-psi; the samples reached saturation in saltwater after 56 days. The variation …

The Dark Side Of Engagement: An Organizational Fairness Perspective, Katherine Naomi Rau

Theses and Dissertations

Employee engagement has long been regarded as a positive phenomenon for organizations and individuals. However, recent investigations into unintended, negative consequences of engagement have illuminated the potential “dark side” of engagement. This research applied an organizational fairness lens by investigating the relationship between engagement and psychological contract fulfillment to explain why engaged employees may experience emotional exhaustion and turnover intentions. Additionally, autotelic personality and job crafting were explored as potential mitigating factors in weakening the relationships between psychological contract breach and emotional exhaustion and turnover intention. While findings across two studies did not support the assertion that engagement was related …

Unraveling The Physics Of Quasar Jets Using Hst Polarimetry, Devon Clautice

Theses and Dissertations

We present a multiwavelength study of three high-power FR II (quasar) jets -- 3C 273, PKS 0637-752, and 1150+497 -- with an emphasis on new high-quality Hubble Space Telescope (HST) optical polarimetry and Chandra X-ray Observatory imaging. Relativistic jets from active galactic nuclei transport energy and mass from the supermassive black hole’s accretion region out to Megaparsec-scale lobes, with effects that feedback into galaxy formation and cluster energetics. We build on recent work which has called into question our fundamental understanding of FR II jet physics, and suggest that highly-efficient particle acceleration must be taking place in situ …

Space Transformation For Open Set Recognition, Atefeh Mahdavi

Theses and Dissertations

Open Set Recognition (OSR) is about dealing with unknown situations that were not learned by the models during training. In OSR, only a limited number of known classes are available at the time of training the model and the possibility of unknown classes never seen at training time emerges in the test environment. In such a setting, the unknown classes and their risk should be considered in the algorithm. Such systems require not only to identify and discriminate instances that belong to the source domain (i.e., the seen known classes contained in the training dataset) but also to reject unknown …

Trajectories Of Depression Severity In The First Semester Of College, Nicole A. Kelso

Has Electricity Deregulation Eliminated The Nuclear Option?: Rethinking The Coasian Ios For Project-Finance Investments, Stephen Dansky

Theses and Dissertations

Installed electric generation capacity in the United States is expected to grow significantly over the next two decades. This raises concern about climate change as several common methods of electricity generation emit greenhouse gases. Nuclear power, which doesn’t create greenhouse gases while generating electricity, has been heavily promoted by the nuclear industry and a segment of the environmental community ever since it was codified by the United Nation’s 26^th Climate Change Conference of the Parties as an acceptable energy source to fight climate change. However, this dissertation establishes that the increased revenue risk and uncertainty created by the deregulation …

Organizational Cultural Entrenchment: Exploring Cultural Antecedents Of Actively Destructive Employee Behaviors As A Manifestation Of Voice In Mergers And Acquisitions, Keith Dellano Holloway

Theses and Dissertations

Mergers and acquisitions are frequently leveraged as a vehicle for company growth. However, many of these transactions fail to yield a positive result and often cause a net loss of shareholder value.

There are many interrelated factors at work within a merger or acquisition. Structure, leadership, finances, strategic fit, market, and price are just a few variables to consider. However, the factor of culture, and the failure of cultural integration, has surfaced in literature as a significant contributor to losses within mergers and acquisitions.

A Statistical Fetch Model For Water Wave Glint Correction Using Worldview-3 Imagery, Amanda Jade Quintanilla

Theses and Dissertations

Sun glint in satellite imagery of the water surface contaminates the upwelling signal received by a detector. Many models exist that attempt to correct for this wave facet effect and phenomena. In this work a model for sun glint correction is created using the comparison of image transects between two nearly simultaneously collected images of the same area, although with differing sensor geometry. One image utilized in this research is almost entirely glint free while the other is contaminated by water wave facet glint. Although many models for removing sun glint exist based on various techniques, none are completely accurate, …

Investigating The Relationship Between Metacognition, Motivation, Self-Regulation Strategy Usage, And Physical Activity Participation, Kay Sharon Stanfield

Theses and Dissertations

There are numerous benefits associated with physical activity. Unfortunately, few people participate in enough daily activity to reap the rewards. Health professionals have explored ways to promote adherence to physical activity and healthy behavior. Evidence shows self-regulation to be a determinant of physical activity. This study investigated the relationship between self-regulation strategy usage and levels of physical activity participation. Additionally, the study examined how motivation (through the perspective of Self-Determination theory) impacts physical activity. Six behavior regulation styles correspond to the degree of motivation (from low to high) on the Self-Determination continuum. A comparison of behavior regulation styles to physical …

Modelling Terrestrial And Potential Extraterrestrial Photopigments Via Density Functional Theory, Dorothea Illner

Theses and Dissertations

In the search for extraterrestrial life, biosignatures play a crucial role in identifying its putative traces. A commonly known and robust biosignature is the Vegetation Red Edge (VRE), which can be described as a sharp increase of reflectance observed from a planet and stems from the light absorption of photopigments in specific regions in the electromagnetic spectrum. For Earth, this VRE is known to occur around 700 nm, however, if the photopigments absorb light in different regions and have different structures the VRE could experience a wavelenght shift.

In this work, Chlorophyll a and a potential photopigment precursor called Phot0 …

An Investigation Of The Interactions Of Gradient Coherence And Network Pruning In Neural Networks, Zachary Yauney

Theses and Dissertations

We investigate the coherent gradient hypothesis and show that the coherence measurements are different on real and random data regardless of the network's initialization. We introduce "diffs," an attempt at an element-wise approximation at coherence, and investigate their properties. We study how coherence is affected by increasing the width of simple fully-connected networks. We then prune those fully-connected networks and find that sparse networks outperform dense networks with the same number of nonzero parameters. In addition, we show that it is possible to increase the performance of a sparse network by scaling the size of the dense parent network it …

"I'Ll Stay Where You Want Me To Stay": How Latter-Day Saints Navigate Conflicting Social Values While Remaining Committed To Their Faith, Venice Jardine

Theses and Dissertations

While recent efforts in religious studies have focused on why many Americans seem to be leaving religion entirely, much less is understood about why many others choose to remain committed to their faith--especially when they hold many of the same social values, doubts, or divergent opinions that others cite for leaving. Within a Latter-day Saint context especially, very little research has been done to explore the experiences of those navigating the complexities of competing ethical affordances while remaining committed to their faith. Through ethnographic research in both Salt Lake County and New York City, I document the patterns and processes …

Investigation Of The Regional Innovation System In Rural Region Of New Jersey: A Qualitative Single Case Study, Ketan N. Gandhi

Theses and Dissertations

This single-case study investigated how a partnership between a rural community college in New Jersey and a manufacturer of emerging optics equipment reflected the “regional networked innovation system,” a type of regional innovation system (Asheim & Isaksen, 2002, p.83). The regional innovation system explains a region's development and competitiveness based on a set of actors within a region, developing specific forms of capital derived from social relations, norms, values, and interactions with the community (Doloreux & Parto, 2005).

Physical Activity, Cardiorespiratory Fitness And All-Cause Mortality, Jorin Dane Larsen

Theses and Dissertations

Introduction Both elevated levels of physical activity (PA) and high cardiorespiratory fitness (CRF) are associated with a decreased risk of all-cause mortality. The degree to which an individual's PA level and CRF status interact to influence mortality is not currently fully understood. This study investigated whether PA and CRF were independently related to all-cause mortality, and to what degree PA was associated with improved mortality risk in individuals with low CRF. Methods This is a prospective cohort study using health assessments on individuals gathered between 1975 and 2002. Health assessment data were matched with the National Death Registry to assess …

Conservation And Management Of Greater Sage-Grouse In Strawberry Valley: Quantifying Influences On A Traditional Capture Method And Long-Term Trends In Clutch Size, Janae Radke

Theses and Dissertations

The greater sage-grouse (Centrocercus urophasianus) is a species of conservation concern that has undergone serious declines in the last century. The Strawberry Valley sage grouse population in Utah underwent such a decline from an estimated 3,500 sage grouse in the 1930s to 150 sage grouse in the early 2000s. This decline initiated a long-term conservation and monitoring project in Strawberry Valley with the goal of preserving the sage grouse population. As part of this ongoing conservation project, we investigated factors that impact the success of capturing sage grouse using the night-lighting method (Chapter 1). We found that capture success is …
