The findings support the theory of image repair in that transparency in communication and public relations are important aspects in the world of professional sports as offenders work to deter or repair any damage to their reputation in the midst of a scandal. In addition to providing a unique perspective on image repair …


Cross-Culture Research: Comparison Between Chinese And American Art Education, Ye Liang Mar 2019

Cross-Culture Research: Comparison Between Chinese And American Art Education, Ye Liang

Theses and Dissertations

Education systems in China and the United States are very different. Chinese educator Hong Wang compared the two education systems and came to a conclusion: Chinese education wins in the starting point, while American education wins in the end point (Cheng, 2014). Chinese students learn more things, take challenging courses, and do well in academic accomplishment. However, examination-oriented methods in the Chinese education system may kill students’ interest in learning. Even though Chinese students learned fast in the starting points, they failed in the terminal points as they lost their interest in learning (Chen, 2014). Many educators and scholars think …

Effect Of Support, Preparations Methods, Ag Promotion And Nc Size On The Activity, Selectivity And Sintering Deactivation Of Supported Co Fischer-Tropsch Catalyst, Mahmood Rahmati

Theses and Dissertations

A series of silver-promoted, 20 wt% cobalt Fischer-Tropsch synthesis (FTS) catalysts supported on an alumina modified with 5 wt% silica were prepared using two methods: traditional incipient wetness impregnation (IWI) and a new solvent-deficient precipitation (SDP) technique. Catalysts containing silver promoter concentrations of 0.3, 0.6, 1.2, and 2.5 wt% were prepared using each of the two methods. Silver improved the reducibility of the cobalt significantly, lowering reduction temperatures by up to 100°C, and increasing the extent of reduction by up to 35%. Further, in both preparation methods, changing the silver loading altered the cobalt dispersion. The smallest Co crystallite size …


Sociocultural Identification With The United States And English Pronunciation Comprehensibility And Accent Among International Esl Students, Christinah Paige Mulder Mar 2019

Sociocultural Identification With The United States And English Pronunciation Comprehensibility And Accent Among International Esl Students, Christinah Paige Mulder

Theses and Dissertations

Sociocultural identity is defined for this study as the element of identity affixed to a social or cultural group. Previous research on sociocultural identity has recognized the need for further study of its effect on second language performance, particularly pronunciation. Previous studies have found contradictory results when studying the relationships between sociocultural identity and various measures of second language pronunciation. This thesis takes a quantitative correlational approach to the study of sociocultural identification with the United States and English pronunciation comprehensibility and accent in a group of 68 international students learning English in the United States. Participants completed a survey …


Wasatch Front Atmospheric Deposition Reflects Regional Desert Dust And Local Anthropogenic Sources, Michael Max Goodman Mar 2019

Wasatch Front Atmospheric Deposition Reflects Regional Desert Dust And Local Anthropogenic Sources, Michael Max Goodman

Theses and Dissertations

Dust originating from dry lakes contributes harmful and toxic elements to downwind urban areas and mountain snowpack that is compounded by local contaminant inputs from anthropogenic sources. To evaluate dust contributions to an urban area from regional playas, we sampled playa dust sources, urban dust deposition, and snow dust deposition in central Utah, USA. Samples were analyzed for grain size, mineralogy, and chemistry. Bulk mineralogy between playa, urban, and snow dust samples was similar, with silicate, carbonate, and evaporite minerals. Grain size distribution between fine playa, urban, and snow dust particles was also similar. Elements found at high concentrations in …

A total of 13 studies met the inclusion criteria. Each study was coded based on a quality of evidence coding protocol and the findings were then …


Evolving Collections, Nathan Thomas Williams Mar 2019

Evolving Collections, Nathan Thomas Williams

Theses and Dissertations

My art practice begins with the collecting, processing, and organizing of materials. Through experimentation, I have developed processes centered around a commitment of time and devotion to the plainest beauty of these found materials, their inherent properties, and related systems, making the resulting objects of order possible. Through my application of these personal ordering systems, I strive to bring intrigue and focus to the common and discarded. The process of finding and organizing common surplus materials has given me an understanding of myself, seeing things that may never have occurred were it not for these experiences. This practice has taken …


The Uncanny Mind: Perpetrator Trauma In Poe’S “The Black Cat”, Bethanie Allyson Sonnefeld Mar 2019

The Uncanny Mind: Perpetrator Trauma In Poe’S “The Black Cat”, Bethanie Allyson Sonnefeld

Theses and Dissertations

Among the psychological interpretations of Edgar Allan Poe’s “The Black Cat,” trauma theory has yet to make an appearance. However, the confessional nature of the story shifts—via a trauma reading—from an attempt by the narrator to ease his guilt to his attempt to understand what happened to him. The narrator’s murder of his wife traumatized him, causing erasures in the timeline and several forms of dissociation. These erasures and dissociations cause an uncanny effect within the story, which occurs as the past, present, and future are conflated and as the narrator’s mind is both known and hidden. The narrator’s tale …


Developing A Method To Identify Horizontal Curve Segments With High Crash Occurrences Using The Haf Algorithm, Joseph Stuart Browning Mar 2019

Developing A Method To Identify Horizontal Curve Segments With High Crash Occurrences Using The Haf Algorithm, Joseph Stuart Browning

Theses and Dissertations

Crashes occur every day on Utah’s roadways. Curves can be particularly dangerous as they require driver focus due to potentially unseen hazards. Often, crashes occur on curves due to poor curve geometry, a lack of warning signs, or poor surface conditions. This can create conditions in which vehicles are more prone to leave the roadway, and possibly roll over. These types of crashes are responsible for many severe injuries and a few fatalities each year, which could be prevented if these areas are identified. This highlights a need for identification of curves with high crash occurrences, particularly on a network-wide …

Theses and Dissertations

In this new digital age, efficiency, quality and competition are all increasing rapidly as companies leverage the Industrial Internet of Things (IIoT). However, while industrial innovation moves at a faster and faster pace, educational institutions have lagged in the development of the curriculum and environment needed to support further development of the IIoT. To fully realize the potential of the IIoT in the manufacturing sector educational institutions must support the technological training and education rigor demanded to instill the skills and thought leadership to move the industry forward. The purpose of this research is to provide an IIoT core system …


Pedestrian Walking Speeds At Signalized Intersections In Utah, Jordi Jordan Berrett Mar 2019

Pedestrian Walking Speeds At Signalized Intersections In Utah, Jordi Jordan Berrett

Theses and Dissertations

The 2009 edition of the Manual on Uniform Traffic Control Devices (MUTCD) recommends a pedestrian walking speed of 3.5 feet per second for use in the timing of pedestrian clearance intervals at signalized intersections (reduced from 4.0 feet per second in the 2003 edition). Jurisdictions across the state of Utah continue to maintain pedestrian walking speeds of 4.0 feet per second for normal intersections with guidance on engineering judgement for areas where a lower pedestrian walking speed should be considered. In 2018, it was decided that the current state guidance with regard to pedestrian walking speeds be evaluated for any …


Analog Adaptive Calibration For Arbitrary Phased Array Configuration, Mark William Nielson Mar 2019

Analog Adaptive Calibration For Arbitrary Phased Array Configuration, Mark William Nielson

Theses and Dissertations

The development of phased array antenna systems requires considerable resources and time. Due to this constraint, the Naval Air Command (NAVAIR) needs a phased array that can be physically reconfigured to meet the demands of multiple missions without added development time or cost. This work develops and demonstrates a solution to this problem by implementing an adaptive calibration approach to the development of electronically steerable antennas (ESAs). In contrast to previous analog adaptive beamformer systems, this system allows for an arbitrary antenna configuration with a variable number of antenna elements and locations. A simulation model of arbitrary phased array configurations …


"Yup, So-Jeer": Interlanguage And Ruptured Translation In Charles Dickens's The Perils Of Certain English Prisoners, Jacob Kurt Nielsen Mar 2019

"Yup, So-Jeer": Interlanguage And Ruptured Translation In Charles Dickens's The Perils Of Certain English Prisoners, Jacob Kurt Nielsen

Theses and Dissertations

Co-authored by Charles Dickens and Wilkie Collins, The Perils of Certain English Prisoners is a tale of linguistic subversion in colonial spaces. Christian George King-a native "Sambo" that betrays the English colonists on Silver Store to a marauding band of pirates-demonstrates a linguistic phenomenon that scholars call interlanguage, or a quasi-language that partially resembles both English and his native language. Because of its status as a language between languages, King's interlanguage disrupts the linguistic hierarchy of the tale by opening possibilities for miscommunication. To combat this underlying tension, the colonists must rely on translation-specifically, on the mistaken belief that all …

Carbon Capture And Synergistic Energy Storage: Performance And Uncertainty Quantification, Christopher Stephen Russell

Theses and Dissertations

Energy use around the world will rise in the coming decades. Renewable energy sources will help meet this demand, but renewable sources suffer from intermittency, uncontrollable power supply, geographic limitations, and other issues. Many of these issues can be mitigated by introducing energy storage technologies. These technologies facilitate load following and can effectively time-shift power. This analysis compares dedicated and synergistic energy storage technologies using energy efficiency as the primary metric.
Energy storage will help renewable sources come to the grid, but fossil fuels still dominate energy sources for decades to come in nearly all projections. Carbon capture technologies can …


The Sap Link: A Controller Architecture For Secure Industrial Control Systems, Matthew Cody Wyman Feb 2019

The Sap Link: A Controller Architecture For Secure Industrial Control Systems, Matthew Cody Wyman

Theses and Dissertations

Industrial Control Systems are essential to modern life. They are utilized in hundreds of processes including power distribution, water treatment, manufacturing, traffic management, and amusement park ride control. These systems are an essential part of modern life and if compromised, could result in significant economic loss, safety impacts, damage to the environment, and even loss of life. Unfortunately, many of these systems are not properly secured from a cyber attack. It is likely that a well-funded and motivated attack from a nation-state will successfully compromise an industrial control system's network. As cyber war becomes more prevalent, it is becoming more …


"I Dare Not Venture A Judgement”: Spirituality And The Postsecular In Hogg’S Confessions, Conor Bruce Hilton Feb 2019

"I Dare Not Venture A Judgement”: Spirituality And The Postsecular In Hogg’S Confessions, Conor Bruce Hilton

Theses and Dissertations

Reading James Hogg’s 1824 novel The Private Memoirs and Confessions of a Justified Sinner through a postsecular lens provides a new framework for spirituality. This framework establishes spirituality as a place of tension and uncertainty between the text’s main ideologies—Enlightenment rationality and religious, specifically Calvinist, fanaticism. The text explores this place of tension through its doubled narrative structure and by demonstrating the crisis of faith that the fictional Editor of the text undergoes. Confessions brings a compelling new paradigm to discussions of the postsecular that allows insight into the complex intersections of Enlightenment rationality and empiricism as well as religious …


Attachment And Relationship Quality: A Longitudinal Cross-Lagged Panel Model Examining The Association Of Attachment Styles And Relationship Quality In Married Couples, Meagan Cahoon Alder Feb 2019

Attachment And Relationship Quality: A Longitudinal Cross-Lagged Panel Model Examining The Association Of Attachment Styles And Relationship Quality In Married Couples, Meagan Cahoon Alder

Theses and Dissertations

This is a longitudinal cross-lagged panel model examining the bi-directional association of attachment styles and relationship quality in a community sample of 355 married couples, with at least one child between 10-14 years of age at the beginning of the study and 17-21 years of age at the end of the study. An Actor-Partner Interdependence Model (APIM), was used to test for actor and partner effects, thereby accounting for the non-independent nature of the data. Two separate APIM models were tested with Male Attachment predicting Female Relationship Quality and Female Attachment predicting Male Relationship Quality. Results indicate that own attachment …


Emergence Of Collective Behaviors In Hub-Based Colonies Using Grammatical Evolution And Behavior Trees, Aadesh Neupane Feb 2019

Emergence Of Collective Behaviors In Hub-Based Colonies Using Grammatical Evolution And Behavior Trees, Aadesh Neupane

Theses and Dissertations

Animals such as bees, ants, birds, fish, and others are able to efficiently perform complex coordinated tasks like foraging, nest-selection, flocking and escaping predators without centralized control or coordination. These complex collective behaviors are the result of emergence. Conventionally, mimicking these collective behaviors with robots requires researchers to study actual behaviors, derive mathematical models, and implement these models as algorithms. Since the conventional approach is very time consuming and cumbersome, this thesis uses an emergence-based method for the efficient evolution of collective behaviors. Our method, Grammatical Evolution algorithm for Evolution of Swarm bEhaviors (GEESE), is based on Grammatical Evolution (GE) …


Schur Rings Over Infinite Groups, Cache Porter Dexter Feb 2019

Schur Rings Over Infinite Groups, Cache Porter Dexter

Theses and Dissertations

A Schur ring is a subring of the group algebra with a basis that is formed by a partition of the group. These subrings were initially used to study finite permutation groups, and classifications of Schur rings over various finite groups have been studied. Here we investigate Schur rings over various infinite groups, including free groups. We classify Schur rings over the infinite cyclic group.


Doxastic Voluntarism And Religious Diversity, Naomi Smith Jan 2019

Doxastic Voluntarism And Religious Diversity, Naomi Smith

Undergraduate Honors Theses

The reality of religious diversity raises questions about belief-formation, rationality, and epistemic peerhood. Doxastic voluntarism, the view that we can choose to form certain beliefs, is one proposed account of how we form beliefs in the absence of empirical evidence or conclusive reasoning, which is generally the case with religious beliefs. Direct doxastic voluntarism is the view that in some cases, we exercise immediate control over the beliefs we form. Indirect doxastic voluntarism is the view that we can only exercise control over some factors surrounding the belief-formation process but that this control nonetheless constitutes a choice of belief. I …


Using Coherence To Improve The Calculation Of Active Acoustic Intensity With The Phase And Amplitude Gradient Estimator Method, Mylan Ray Cook Jan 2019

Using Coherence To Improve The Calculation Of Active Acoustic Intensity With The Phase And Amplitude Gradient Estimator Method, Mylan Ray Cook

Theses and Dissertations

Coherence, which gives the similarity of signals received at two microphone locations, can be a powerful tool for calculating acoustic quantities, particularly active acoustic intensity. To calculate active acoustic intensity, a multi-microphone probe is often used, and therefore coherence between all microphone pairs on the probe can be obtained. The phase and amplitude gradient estimator (PAGE) method can be used to calculate intensity, and is well suited for many situations. There are limitations to this method—such as multiple sources or contaminating noise in the sound field—which can cause significant error. When there are multiple sources or contaminating noise present, the …


The Security Layer, Mark Thomas O'Neill Jan 2019

The Security Layer, Mark Thomas O'Neill

Theses and Dissertations

Transport Layer Security (TLS) is a vital component to the security ecosystem and the most popular security protocol used on the Internet today. Despite the strengths of the protocol, numerous vulnerabilities result from its improper use in practice. Some of these vulnerabilities arise from weaknesses in authentication, from the rigidity of the trusted authority system to the complexities of client certificates. Others result from the misuse of TLS by developers, who misuse complicated TLS libraries, improperly validate server certificates, employ outdated cipher suites, or deploy other features insecurely. To make matters worse, system administrators and users are powerless to fix …
