Essays In The Economics Of Tournaments, Eren Bilen

Theses and Dissertations

This dissertation consists of three essays that focus on tournaments, incentives, and performance. The first essay presents evidence of cheating that took place in online examinations during COVID-19 lockdowns and proposes two solutions with and without a camera for the cheating problem based on the experience accumulated by online chess communities over the past two decades. The best implementable solution is a uniform online exam policy where a camera capturing each students computer screen and room is a requirement.

The second essay investigates the "superstar effect" using observations from chess tournaments. Superstars exist in many places. In competition, they might …

“Where Beauty And Anguish Had Contended”: Eden, Gender, And Creativity In Melville’S Pierre, Kersey Reynolds

Theses and Dissertations

Much critical interest regarding incest in Pierre has been focused horizontally on the Glendinning family tree, in terms of the brother-sister relationship forged between Pierre Glendinning and Isabel Banford. But this thesis evaluates incest within Melville’s scheme of creativity and gender in the novel. As Sandra M. Gilbert and Susan Gubar have established, to author a text is to become owner of its subjects—a father of one’s “brain-children” (Gilbert and Gubar 7). So, as Pierre writes Isabel into the Glendinning name, the incestuous relationship between Pierre and Isabel may be viewed through the lens of a father-daughter dynamic between the …

Experimental Evaluation Of Drying Spent Nuclear Fuel For Dry Cask Storage Through Vacuum And Forced Helium Dehydration, Jonathan Ellis Perry

Theses and Dissertations

Currently approximately 80,000 tons of spent nuclear fuel (SNF) are in either dry or wet storage at nuclear power plants or designated spent fuel storage facilities. Over 2,000 tons are added to that sum each year. All SNF must be dried to an accepted Nuclear Regulatory Commission (NRC) drying criteria before being placed in dry storage. Inadequately drying SNF increases the risk of detrimental effects to the fuel while in dry storage. Two commonly used drying operations in the nuclear industry are vacuum drying and forced helium dehydration (FHD). Although these drying processes have been used for many years, there …

This study aims to provide a better understanding of age and sex dependency of cell and extracellular matrix alterations of the aortic wall during the progression of the aneurysm caused by Marfan syndrome. To achieve this goal, the C1041G/+ mouse model of Marfan syndrome …

The Determinants And Consequences Of Foreign Direct Investment, Alexandra Dinu Troidl

Theses and Dissertations

This dissertation examines the regional economic effects of foreign direct investment (FDI). FDI is known to have benefits for both national and regional economies. These benefits include an increasing number of higher paying jobs, productivity spillovers for local firms, and elevated economic development (SelectUSA, 2020). Many governments compete to attract large FDI projects, often through the use of controversial incentive packages. Incentives are criticized because it is not clear that they affect the location of FDI and furthermore, whether the benefit of incentives outweigh the costs (Bartik, 2018).

In the first paper, I assess the impact of incentives on the …

Military Communities And Natural Hazards In The United States, Logan Lee

Theses and Dissertations

The vulnerability and resilience of communities to hazards is a concept that has gained traction in the research community in recent decades. Climate change, combined with increasing damages from natural hazards, has energized researchers and practitioners alike to identify the risks to people and places from future losses. Military communities support large military bases and are composed of service members, their families, and civilian populations alike. Due to the presence of military installations and military populations, the characteristics of the population and influences in military communities are unique. However, there is a gap in current research to assess whether the …

Sparse Modeling For Predicting Class Assignments For Trace Forensic Evidence, Dayla Christine Rich

Theses and Dissertations

Numerous disciplines in forensic science utilize various types of spectral data when analyzing evidence. Spectral techniques are particularly critical for the analysis of trace evidence, as these methods are normally non-destructive. Preserving evidence, especially trace evidence, is of high priority in a forensic laboratory setting. Once a piece of evidence has been fully consumed, no more analyses can be performed. Typically, visual comparison, or spectral overlay, is performed to compare questioned samples (evidence) to standards or knowns. However, such an approach may not be optimal in distinguishing the subtle, yet highly important, discriminating characteristics present in the spectra. As statistical …

Rehabilitation Of Timber Piles Using Fiber Reinforced Polymers Analyzed With Acoustic Emission, Rebekah Marie Krol

Theses and Dissertations

Assessing the current state of infrastructure and implementing strengthening or rehabilitation methods on old or damaged members is important to ensure safety and longevity of structures. Non-destructive testing is an important tool for localizing and characterizing damage in structures, especially structures that are more susceptible to damage because of age or environment. In addition to locating inadequate members, it is essential to have a repair technique in place so that the structure can continue to be used in a safe manner.

This study aims to review the use of acoustic emission for evaluating damage obtained in timber piles subjected to …

Effects Of Personal Fm System Use During Phonological Awareness Instruction For Children At Risk For Dyslexia, Gabriella Rose Reynolds

Theses and Dissertations

Students with reading impairments, including dyslexia, account for the largest proportion of students receiving special education services in the United States (NCES, 2016). Developmental dyslexia is characterized by slow and inaccurate word decoding (Lyon et al., 2003). This word decoding difficulty results from deficits in phonological awareness, a sound-based skill (Swan & Goswami, 1997). Classrooms are known to have high levels of background noise and are inconsistent with recommendations for optimal listening (Picard & Bradley, 2001) or accepted standards (ASHA, n.d.). Furthermore, degraded acoustic conditions have been related to poorer performance on speech-recognition tasks even for children with normal hearing …

Improving Access To Teacher Mentors For Black Students: The Mediating Role Of School Safety, Anna Flitner

Theses and Dissertations

Having a teacher mentor is associated with several positive outcomes, yet teacher mentors are not distributed evenly among youth, and children who are Black are substantially less likely to form mentoring relationships with teachers. In this study I tested a putative explanatory hypothesis for differences between Black and White children’s access to teacher mentors. Data from Waves I and III from the National Longitudinal Study of Adolescent Health were used. Linear regression models were used to predict the access to teacher mentors and a mediational analysis was conducted to determine the effect of school safety on the relationship between race …

A Culture Of Control: Progressive Era Eugenics In South Carolina As A Continuation Of Created White Supremacy, Hannah Nicole Patton

Theses and Dissertations

This work examines the evolution of eugenic ideology in South Carolina during the Progressive Era by following relevant discussions published in The State newspaper. Between 1891 and 1939, The State newspaper provided a platform for discussions about eugenic ideology to be disseminated to the general public. Through eugenics the white portion of the South Carolina population saw a way to retain white supremacy and create better progeny. An examination of The State reveals a network of discussions that reached across South Carolina, the United States, as well as Western Europe. The existence of newspaper articles illustrates cultural integration in the …

A Unified Approach To Estimating The Intraclass Correlation Coefficient And Its Bias: An Exploratory Study, Kelvin Terrell Pompey

This research study was grounded in the conceptual framework that motivating and engaging students in the classroom (with the introduction of technology) can be very difficult. This study seeks to determine the relationship between student engagement and motivation as classroom lessons are moved along the different levels of the SAMR model, which stands for substitution, augmentation, …

Investigating The Dynamic Interactions Of Rapidly Growing Precocial Shorebird Chicks, Luke R. Wilde

Theses and Dissertations

Organisms in dynamic environments must continually reassess the cost-benefit trade-offs of their interactions and adjust their behaviors accordingly. Nevertheless, ecological research often takes a ‘snapshot’ approach to studying interactions across sample locations and timepoints. Investigating ecological interactions in this way can miss important information about the influence spatiotemporal context has on the scale and direction of their effects. Longitudinal studies that follow individuals can elucidate how changing contexts affect an individual’s ecology while deepening our understanding of adaptive behavior. However, determining how context influences the effect of an interaction requires it be measured across a range of spatiotemporal conditions. Studying …

The Rising Of The Avant-Garde Movement In The 1980s People’S Republic Of China: A Cultural Practice Of The New Enlightenment, Jingsheng Zhang

Theses and Dissertations

This dissertation, entitled “The Rising of the Avant-garde Movement in 1980s People’s Republic of China: A Cultural Practice of the New Enlightenment,” deals with Chinese avant-garde literature and art in the reform era of the 1980s, when the People’s Republic of China was turning from high socialism to state capitalism. Scholars of Chinese studies have deemed avant-garde texts as counter-narratives of enlightenment, which was a main ideology and national agenda of the reform era. This dissertation reexamines this established statement by shifting focus from the traditional hermeneutic approaches to a sociological study of the generative conditions of avant-garde literature and …

Measurement Of N* Cross-Sections From Single-Pion Electroproduction At Low Q^2, Nicholas Scoville Tyler

Theses and Dissertations

Measurements of nucleon electroexcitation resonance cross-sections give unique insight into the dynamics of the strong interaction and our knowledge of Quantum Chromodynamics (QCD). The analysis of exclusive electroproduction data is an important tool in understanding the structure of the nucleon and its excited states. Exclusive channels give a clear way to extract the desired resonant contributions from non-resonant contributions. A gap in the helicity amplitudes extracted from single-pion cross-section data exists for virtual photon momentum transfers ($Q^2$) in the range of $1-2~\mathrm{GeV}^{2}$. Using data collected by the CEBAF Large Acceptance Spectrometer (CLAS) detector with a beam energy of $4.8~\mathrm{GeV}$, the …

Effect Of Oxidative Stress On Lifespan And Cellular Survival, Benedicth Onyeka Ukhueduan

Theses and Dissertations

When cells experience oxidative stress, the integrated stress response (ISR) signaling pathway is activated. One of the first outcomes of such ISR-activated response is to temporarily halt protein synthesis, which aids in cellular recovery. However, if cells cannot recover from the stress, they activate the cell death pathways which kills the affected cells, usually by apoptosis, which can then lead to either acquisition or prevention of diseases depending on the situation. In physiological aging, a compromised stress response is observed as an organism ages, which leads to disrupted homeostasis and elevated risk of disease. Thus, longevity of an organism is …

Examination Of Energy Needs And Female Athlete Triad Components In Competitive Cheerleaders, Allison Smith

Theses and Dissertations

The sport of cheerleading has grown immensely over the recent decades. The current sport requires full body athletic abilities like gymnastics, ballet, and swimming and diving. These sports have previously reported high rates of eating disorder (ED) risk, body image dissatisfaction, and Female Athlete Triad (Triad) components (low energy availability with or without and eating disorder, menstrual cycle dysfunction, and low bone mineral density). Scientific research examining these factors within cheerleaders has been limited. The purpose of this study was to examine overall ED risk across cheerleading team type (All-Star, college), squad type (all-girl, coed), and by position (flyer, base, …

Applications And Mechanisms Of Near Infrared Spectroscopy For Age Estimation In Otoliths Of Red Snapper Lutjanus Campechanus, Michelle S. Passerotti

Theses and Dissertations

Near infrared spectroscopy (NIRS) is a light spectroscopy method useful for non-invasively discriminating and quantifying chemical composition of a wide variety of substances. Recently-developed applications of NIRS to fish age estimation across a range of taxa have sparked intense interest in exploring the feasibility of its use for rapid age estimation in fisheries population management. In this pursuit, development of species-specific calibration models relating traditionally-derived age estimates (i.e., those estimated from growth band counts) to NIR spectral signatures from ageing structures is required to derive predictive models that can then estimate age from rapid scans of whole ageing structures alone. …
