Jackknife Empirical Likelihood Tests For Equality Of Generalized Lorenz Curves, Anton Butenko

Electronic Theses, Projects, and Dissertations

A Lorenz curve is a graphical representation of the distribution of income or wealth within a population. The generalized Lorenz curve can be created by scaling the values on the vertical axis of a Lorenz curve by the average output of the distribution. In this thesis, we propose two nonparametric methods for testing the equality of two generalized Lorenz curves. Both methods are based on empirical likelihood and utilize a U -statistic. We derive the limiting distribution of the likelihood ratio, which is shown to follow a chi-squared distribution with one degree of freedom. We conduct simulations to compare the …

Attitudes Of Social Work Students On The Use Of Psychedelics As A Mental Health Treatment In Clinical Settings, Amanda Nickles

Electronic Theses, Projects, and Dissertations

Although psychedelic substances are currently categorized under federal law as a Schedule I controlled substance, there has recently been a renewed interest in the use of psychedelics to treat a number of mental health and substance use disorders. Research is garnering positive results in clinical trials, although much fear and stigma still surrounds psychedelic use. Future social workers’ presence in both macro level practices, advocating for mental health treatments and access to care, as well as their work in micro level clinically focused practices adds to their relevancy and legitimacy in advocating for potential policy changes on therapeutic psychedelic usage …

Knot Equivalence, Jacob Trubey

Electronic Theses, Projects, and Dissertations

A knot is a closed curve in R3. Alternatively, we say that a knot is an embedding f : S1 → R3 of a circle into R3. Analogously, one can think of a knot as a segment of string in a three-dimensional space that has been knotted together in some way, with the ends of the string then joined together to form a knotted loop. A link is a collection of knots that have been linked together.

An important question in the mathematical study of knot theory is that of how we can tell when two knots are, or are …

With Liberty And Justice For All? Examining The Role Of Hegemony Throughout U.S. History In Influencing Multilingual Discriminatory Practices Within Academic Policies And Legislation, Katie Olivia Wallen

Electronic Theses, Projects, and Dissertations

The discriminatory systems that multidialectal and multilingual users experience in the United States have historically influenced how educators and policymakers approach the construction of academic policies and curricula. These hegemonic systems shape and inform linguistic attitudes that have continually imparted prejudice against non-White language users, resulting in a gap of inclusivity for diverse student populations. Research aiming to address this gap has traditionally approached linguistic discrimination by specifically examining the use of dialects or non-English languages in the classroom rather than the underlying systems that affect both multidialectal and multilingual users similarly. Through the lens of policy and social construct …

Human Suspicious Activity Detection, Nilamben Bhuva

Electronic Theses, Projects, and Dissertations

The detection of suspicious human activity is a crucial aspect of ensuring public safety and security. The aim is to identify suspicious behavior. To accomplish this, we employ the LRCN, a long-term recurrent convolutional network, to detect anomalous activity. It is important to consider the temporal data of the video when classifying suspicious behavior, and the framework uses a combination of CNNs and RNNs to analyze video frames and extract relevant features. The key milestones of this project include conducting research, collecting and pre-processing data, designing and training the model, and evaluating its performance. The resulting detection system can accurately …

The study used a qualitative, exploratory design. The data was collected from in depth interviews with six participants who …

How Stigma Impacts The Utilization Of Mental Health Services Among Young Adults' Within Three Different Ethnic Minority Communities, Ivette Garcia, Melissa E. Gomez

Electronic Theses, Projects, and Dissertations

Mental health is an important aspect of every individual’s life. However, regardless of its importance, mental health is a topic that does not get much recognition. It is often simply brushed under the rug and ignored. Consequently, individuals who have mental health diagnoses may or may not choose to seek the necessary assistance. This specifically seems to be the case among adolescents and young adults within various ethnic communities, which may be due to the stigma surrounding mental health in their communities. To illustrate, regardless of the high prevalence rate of mental health issues among the minority youth, many of …

“Too Good To Kill”: Literary Gerontology And Late Style In Margaret Atwood’S Gilead Novels, Serina Item

Electronic Theses, Projects, and Dissertations

Margaret Atwood’s 1985 novel, The Handmaid's Tale, and her 2019 sequel, The Testaments, illuminate the author’s continued interest in the connection between a woman’s age and the notion of her usefulness and complicity within a hegemonically masculine society. Focusing on literary gerontology and the author’s late style, this essay highlights Atwood’s persistent rejection of patriarchal representations of older women in literature. I analyze the ways in which Atwood’s “ustopian” (Atwood’s literary genre invention, combining “dystopia” and “utopia”) novels develop older women characters beyond “old age as motif and metaphor” by removing age and gender as significant barriers to …

Distance Correlation Based Feature Selection In Random Forest, Jose Munoz-Lopez

Electronic Theses, Projects, and Dissertations

The Pearson correlation coefficient is a commonly used measure of correlation, but it has limitations as it only measures the linear relationship between two numerical variables. In 2007, Szekely et al. introduced the distance correlation, which measures all types of dependencies between random vectors X and Y in arbitrary dimensions, not just the linear ones. In this thesis, we propose a filter method that utilizes distance correlation as a criterion for feature selection in Random Forest regression. We conduct extensive simulation studies to evaluate its performance compared to existing methods under various data settings, in terms of the prediction mean …

Transforming Black Students’ Higher Education Experiences And Lives: A Proposal For The Csu, Don Lundy

Electronic Theses, Projects, and Dissertations

For decades, a racial “achievement gap” has persisted in U.S. higher education. Specifically, White students have outperformed Black students on a number of indicators, including college admissions, standardized test scores, and graduation rates. This graduate project considers several explanations for this persistent inequity. The root of the problem, it argues, is U.S. higher education’s history of racism and exclusion and the oversaturation of whiteness in these institutions. In other words, U.S. higher education was built for and continues to serve White students at the expense of Black students. Historically Black Colleges and Universities (HBCUs) show us that when whiteness is …

Reverse Mathematics Of Ramsey's Theorem, Nikolay Maslov

Electronic Theses, Projects, and Dissertations

Reverse mathematics aims to determine which set theoretic axioms are necessary to prove the theorems outside of the set theory. Since the 1970’s, there has been an interest in applying reverse mathematics to study combinatorial principles like Ramsey’s theorem to analyze its strength and relation to other theorems. Ramsey’s theorem for pairs states that for any infinite complete graph with a finite coloring on edges, there is an infinite subset of nodes all of whose edges share one color. In this thesis, we introduce the fundamental terminology and techniques for reverse mathematics, and demonstrate their use in proving Kőnig's lemma …

Examining The Association Between Family Cohesion And The Risk Of Substance Use In Offspring, Angelica Mendoza

Electronic Theses, Projects, and Dissertations

Background and Purpose: Progress has been made in understanding substance use and its transmission, whether it be biological or environmental, yet there is a lack of research in understanding protective factors and the disruption of developing a substance use disorder. The study was aimed to fill the gap in our understanding of protective factors against familial transmission of substance use disorders by examining the association between family resilience and the risk of transmission to an offspring. We hypothesized that those without a substance use diagnosis would have higher levels of family functioning compared to those with a substance use diagnosis. …

Late Holocene Slip History Of The Central Garlock Fault, Mojave Desert, California, James Eric Burns

Electronic Theses, Projects, and Dissertations

This study investigates the late Holocene slip history of the central Garlock Fault, using measurements of left-lateral offsets of alluvial features from airborne and hand-held LiDAR imagery, drone photogrammetry, and field measurements. IRSL dating of the offset late Holocene alluvial deposits was compared to published paleoseismic records to estimate the number of earthquakes that contributed to the offsets. Focus was given to geomorphic features offset in the past 1-4 earthquakes. Results indicate the average slip per earthquake was about 5.75 m (range: 4.75 to 6.25 m) in the past four events in the El Paso Mountains (EPM) and was 4.3-7.3 …

Development Of A Sustainable Social Emotional Learning Workshop Series For Kindergarten To Second Grade Teachers, Claire Reyes

Electronic Theses, Projects, and Dissertations

ABSTRACT

In this project, I propose a Social Emotional Learning (SEL) workshopseries for kindergarten through second-grade teachers. In the recent decade, especially after the COVID-19 pandemic took a toll on mental health, SEL programs have gained attention, and many have recognized the need for these programs in the classroom (Katz,2020). Early integration of SEL (e.g., in early childhood and elementary school classrooms) is essential to lifelong social and emotional development and positive outcomes (Mondi et al., 2021). However, SEL may feel difficult for teachers to incorporate in the classroom; teachers may learn about SEL broadly and inconsistently; thus, they feel …

Preserving Placement For Children With Behavioral Issues: A Qualitative Study Of Child Welfare Social Workers In The United States, Jessica Katelyn Quin, Tara Belle Beam

The Intersection Of Nfts And Structured Finance, Christopher K. Odinet, Andrea Tosato

Faculty Scholarship

Blockchain technology, cryptocurrencies, stablecoins and non-fungible tokens (NFTs) continue to invade financial markets. Whether through partnerships between financial institutions and tech firms or through in-house initiatives at some of the nation’s largest banks, blockchain-based products, services, and transactional structures are a major point of interest. In a recent work by Professor Steven Schwarcz, the growing NFT market is analyzed using the traditional tools of structured finance. Creating a new conceptual model called non-cash-flow monetizations, Professor Schwarcz reveals the risks to investors and markets, if the tokenization of non-traditional and largely illiquid assets proliferates. Having identified the potential harms, he offers …

My goal was to give recommendations to museums and exhibits in Omaha on what …

Characterization Of Differential Rearing And Sex On 5-Ht2ar Receptor Activation, Kelsey Lowe

Theses/Capstones/Creative Projects

The prevalence of substance use disorders (SUDs) continues to rise while the number of medications to combat this deadly disorder remains stagnant. Entirely new thinking about what exemplifies a possible therapeutic is needed. Hallucinogens are continually being studied more as possible treatments for many psychological conditions, including SUDs. Classic hallucinogens engage many serotonin and monoamine systems, but the hallucinogenic effects are driven by serotonin 5-HT_2A receptor (5-HT_2AR) activation. Forced social isolation induces chronic stress, increases 5-HT_2AR expression in the cortex and have been suggested to play a role in the comorbidity between stress, maladaptive coping, …
