First Detrital Zircon Provenance Data From Oligocene-Pleistocene Sediment In The Beaufort-Mackenzie Basin, Arctic Ocean, Joseph Martina

Theses and Dissertations

Sediment, runoff, and nutrient input to the Arctic Ocean plays a critical role in both physical and biological processes that impact regional and global systems. The Beaufort-Mackenzie Basin, situated in the Arctic Ocean offshore northwestern Canada, contains more than 14 km of clastic strata and provides a record of erosion and sediment transport from the Cretaceous to present. Pliocene sedimentation rates within the basin jump nearly 2000% relative to underlying units, but the cause of this shift remains unknown. We used cuttings from the N. Issungnak L-86 well, focusing on the Oligocene-lower Miocene Kugmallit and Mackenzie Bay sequences and the …

Novel Approaches To Combat Neuro-Degradation: Investigations Of Two Supplemental Strategies Aimed At Improving Warfighter Performance, Blaine Lints

Theses and Dissertations

This dissertation examines the efficacy of two distinct nutritional supplementation strategies for improving physical and/or cognitive performance under stress. The first study investigated the effects of 150 mg caffeine plus 150 mg theacrine ingestion in tactically trained individuals. Results indicated that the combination of caffeine and theacrine was associated with significant improvements in reaction time, accuracy, and measures of ocular control following high-intensity interval (HII) exercise. The HII exercise protocol consisted of ten repetitions of 60s high-intensity intervals (≥90% maximal oxygen uptake [VO_2max]) followed by 120s low-intensity intervals (~40% VO_2max) on a treadmill. These benefits were …

Hydrogen Permeation And Mechanical Behavior Of Hydrogen-Charged Cr-Coated And Oxidized Zr-Alloy Fuel Cladding, Daniel Cole Viands

Theses and Dissertations

Following the Fukushima nuclear accident in 2011, accident tolerant fuel (ATF) became a major research interest to enhance the safety of light water reactors. Because the current fleet of light water reactors and their associated fuel cycle infrastructure are well-established, developing ATF that does not significantly alter the current fuel form or change its supporting infrastructure is ideal. Cr-coated Zircaloy fuel cladding is therefore an excellent short-term solution to enhance accident tolerance. Thin layers of Cr-coating offer notable resistance to corrosion, high-temperature oxidation, physical wear, and hydrogen permeation. Cold spray (CS) and physical vapor deposition (PVD) are two well-established Cr-coating …

Getting Poked (Lovingly) With A Stick: A Study Of Parental Involvement During First-Year Students’ College Transitions, Mary Ellis Glymph

Theses and Dissertations

In recent years, some higher education professionals have observed an increase in parental involvement in the lives of their students during their transition to college. While involved parents are sometimes referred to as “helicopter parents,” this new generation of parents often fits more into the label of “snowplow parents” or “lawnmower parents.” This sort of over-involvement impacts students’ personal and academic development far beyond high school graduation; during college, students can struggle to adjust to new levels of academic rigor, but they can also struggle with self-confidence and internal motivation due to their lack of experience with addressing their own …

Spatio-Temporal Modeling & Goodness Of Fit Testing For Ecological Fire Data, Jedidiah Olof Lindborg

Theses and Dissertations

An analysis of fire data sets resulting from controlled burns was performed. Spatio-temporal models were applied to the data sets to determine which covariates are significant in predicting fire temperature. The data sets were censored and only contain temperatures above 300C, due to a limitation in the measuring device. To handle the censoring, an extrapolation was used to reconstruct the temperatures below 300C. Models were created and run for a data set with the extrapolated temperatures and a data set with all censored temperatures removed. Several aspects of the model were evaluated, such as the chosen hyperparameters, the spatial covariance …

Filling In The Gaps: Evaluating A Self-Regulated Learning Strategy For Middle School Students Using Action Research, Leslie Eller Southerland

Theses and Dissertations

The purpose of this action research study was to evaluate the effects of a self-regulated learning innovation on middle school students’ self-regulated learning skills. One way to address problems such as student motivation, student engagement, and distracting behaviors in the classroom is to explicitly teach self-regulated learning skills such as goal setting, strategy use, self-monitoring, and systematic practice. Two research questions guided this study: (1) How and to what extent does a self-regulated learning innovation impact 7th and 8th grade students’ self-regulated learning skills (planning, self-monitoring, evaluation, reflection)? (2) In what ways do 7^th and 8^th grade students …

Theses and Dissertations

This study analyzes the life expectancy for 237 countries from 1950-2023 and the healthcare expenditure for 50 countries from 1970-2022, and how life expectancy and healthcare expenditure relate to each other. Functional Principal Components Analysis was used to analyze the life expectancy and healthcare expenditure for each of the countries. Additionally, the regions of the countries were analyzed to identify any regional trends for the life expectancy data. Due to missing data and the structure of the healthcare data, multiple imputation methods and Principal Component Analysis techniques were explored for the healthcare data. Furthermore, a simulation study was conducted to …

Approaches To Enhancing Multiple Hypothesis Testing Methods With Side-Information, Siyu Zheng

Theses and Dissertations

Lesion-symptom mapping (LSM) studies offer insight into the brain areas involved in various aspects of cognition. This is commonly done via behavioral testing in patients with a naturally occurring brain injury or lesions (e.g., strokes or brain tumors). This results in high-dimensional observational data where lesion status (present/absent) is non-uniformly distributed, with some voxels having lesions in very few (or no) subjects. In this situation, mass univariate hypothesis tests have severe power heterogeneity where many tests are known a priori to have little to no power. Additionally, high-dimensional observational data can be grouped according to brain anatomical structure.

The Case For Indexing: Echocardiographic Dimensions In The Arab Gulf, Adil I. Jumani, Shaini C. Mani, Ghada A. Rashwan, Hadiza O. Ibrahim, Jumaa S. Aldhaheri, Safaa M. Almohdar, Khaled M. Alfakih

Saudi Medical Journal

Objectives: To evaluate echocardiographic parameters in young Emirati males and compare them to American Society of Echocardiography/European Association of Cardiovascular Imaging reference ranges, highlighting the need for population-specific or indexed normal ranges. Echocardiographic reference ranges for cardiac dimensions are primarily derived from Western populations, which may not be suitable for smaller-bodied populations, such as Asians. Methods: Echocardiography was performed on 60 healthy Emirati males undergoing military recruitment from September to December 2024. Measurements included left ventricular (LV), aortic, and left atrial (LA) dimensions and volumes. Parameters were indexed to body surface area (BSA) and compared to established Western norms. Results: …

From Disruption To Integration: Cryptocurrency Prices, Financial Fluctuations, And Macroeconomy, Zhengyang Chen

Faculty Publications

This paper examines cryptocurrency shock transmission to financial markets and the macroeconomy using a Bayesian structural VAR with Pandemic Priors from 2015 to 2024. By affecting overall risk appetite, cryptocurrency price shocks generate positive financial market spillovers, accounting for 18% of equity and 27% of commodity price fluctuations. Real economic effects are significant in driving investment but remain limited, contributing only 4% to unemployment and 6% to industrial production variance. However, cryptocurrency shocks explain 18% of price-level forecast error variance at long horizons. Narrative analysis reveals sentiment and technology as primary shock drivers. These findings demonstrate cryptocurrency's deep financial system …

The Expungement Process: Survey Evidence On Applicant Experiences, Mira Edmonds, J.J. Prescott, Sonja Starr, German Marquez Alcala

Articles

Tens of millions of Americans with publicly accessible criminal convictions face significant collateral consequences that affect their employment, housing, and family life, which not only harm these individuals but also limit society’s access to their skills, productivity, and participation. In response, policymakers have enlarged the scope and enhanced the accessibility of criminal-record expungement laws. Little is known, however, about how individuals perceive, navigate, and take advantage of these new, broader laws. This Article presents findings from a large-scale survey of 1,439 expungement applicants and recipients in Detroit, conducted in partnership with Project Clean Slate (PCS), a city initiative assisting residents …

Navigating Perceptions: How Organizational Type And Message Source Affect Willingness To Fly In Automated Air Taxis, Cody James Sweatt

Doctoral Dissertations and Master's Theses

A new era of transportation and business is beginning to emerge. Advanced air mobility (AAM), which uses highly automated aircraft that transport passengers and cargo in the underutilized, low-altitude airspace above and around urban areas, is rapidly becoming a reality (FAA, 2023). These new companies will utilize air taxis, which are automated, electric, vertical takeoff and landing (eVTOL) aircraft and will potentially foster a revolutionary new commerce infrastructure. Unfortunately, it is not currently understood how the credibility of a message source or specific type of organization that owns and operates an automated air taxi company influences a customer’s willingness to …

Good Faith Estimates And The No Surprises Act, Stuart L. Segelnick Dds, Ms

The New York State Dental Journal

Federal law requires dentists to be up front with self-pay patients about the cost of their treatment. Surprises may lead to penalties.

The No Surprises Act (NSA) went into effect on Jan. 1, 2022. This is a federal law that applies to all health-care providers, including dentists. The law gives certain rights to patients to help protect them from receiving surprise medical bills. These surprises usually occur when a person has no control over who treats them, such as during an emergency or when they are treated unknowingly by an out-of-network provider.
