Constructing And Validating Feature Models Using Relational, Document, And Graph Databases, Hazim Shatnawi Jan 2021

Constructing And Validating Feature Models Using Relational, Document, And Graph Databases, Hazim Shatnawi

Electronic Theses and Dissertations

Building a software product line (SPL) is a systematic strategy for reusing software within a family of related systems from some application domain. To define an SPL, a domain analyst must identify the common and variable aspects of a family of systems and capture them for later use in construction of specific products. To do so, Feature-Oriented Domain Analysis (FODA) introduced the feature model as an abstraction to represent the common and variable aspects, using a feature diagram to depict the model visually. However, this abstraction is often difficult for developers to use because most tools rely on specialized theories, …

The Current Treatment Of English Phrasal Verbs In Mext-Authorized Textbooks For Japanese Junior High School Students, Natsuko Yamada Jan 2021

The Current Treatment Of English Phrasal Verbs In Mext-Authorized Textbooks For Japanese Junior High School Students, Natsuko Yamada

Electronic Theses and Dissertations

This comparative analysis, focusing on the 150 highest-frequency phrasal verbs in the phrasal verb pedagogical list (Garnier and Schmitt, 2015), highlights the limited occurrence across English language textbooks for Japanese junior high school. The spoken and written data of Japanese learners of English (i.e., NICT-JLE and NICE) shows considerable differences in the usage patterns of phrasal verbs compared to native English speakers. These results indicated that Japanese learners’ underdeveloped productive knowledge of phrasal verbs could cause intelligibility problems with native speakers especially in oral communication. In order to overcome the semantic and phonological complexity of phrasal verbs, and to break …


A Valence-Bond Operator Algebra For Quantum Spin Models And Its Applications, Huu Tran Do Jan 2021

A Valence-Bond Operator Algebra For Quantum Spin Models And Its Applications, Huu Tran Do

Electronic Theses and Dissertations

The Heisenberg Hamiltonian is the prototype model for quantum magnetism. The Hamilto- nian includes exchange couplings between vector spins, which are the intrinsic magnetic moments of localized electrons. The classical energy between any pair of interacting spins can be minimized by aligning them parallel (ferromagnetic case) or antiparallel (antiferromagnetic), depending on the sign of the coupling. But quantum fluctuations play a key role, and a full quantum mechanical treatment of the many-body system is generally required. Finding the exact ground-state energy and wave function of isotropic antiferromagnetic (AFM) systems for an arbitrary spin-S and lattice morphology is still a challenging …


Dynamics For Discretized Gravity In The Causal Set Approach, Benjamin Pilgrim Jan 2021

Dynamics For Discretized Gravity In The Causal Set Approach, Benjamin Pilgrim

Electronic Theses and Dissertations

Causal set theory is an approach to quantum gravity which replaces the continuous spacetime manifold with a discrete set of points and a partial order. In this work, I will focus on causal sets embeddable in two-dimensional manifolds, and define an action based on chains which in the continuum limit replicates the Einstein-Hilbert action; furthermore, I will propose a variational principle based on this action and numerically show it can distinguish nonflat manifoldlike causal sets from the most common type of nonmanifoldlike causal sets. I will then supplement this action with a boundary term similar to the Gibbons-Hawking-York boundary term …


Interictal Avoidance Of Sensory Stimuli Among Individuals With Migraine, Daniel Rogers Jan 2021

Interictal Avoidance Of Sensory Stimuli Among Individuals With Migraine, Daniel Rogers

Electronic Theses and Dissertations

Migraine is the most debilitating neurological disorder worldwide and is associated with high economic and psychological costs. Common behavioral strategies for coping with migraine include avoidance of stimuli believed to precipitate an attack, though literature suggests that avoidance behaviors may serve to exacerbate migraine-symptoms and increase disability. Although the incorporation of trigger avoidance in modern conceptualizations of headache-related disability represents a more comprehensive understanding of disability occurring outside of migraine attacks (interictally), extant literature has emphasized trigger avoidance to the exclusion of other factors. Learning principles suggest stimuli that exacerbate migraine may take on similar eliciting properties as pain and …

Chronology Of The Fatherland Site, Daniel Shawl Jan 2021

Chronology Of The Fatherland Site, Daniel Shawl

Electronic Theses and Dissertations

A recently discovered mound (Mound E) at the Grand Village of the Natchez Indians (22AD501, the Fatherland Site) dates to the Foster phase of the Mississippian period (1300-1500 CE). This new chronology is stems from analysis conducted on ceramic assemblages from Robert S. Neitzel’s (1965) excavations and ceramic assemblages from Tony Boudreaux’s (2019) excavations at the site. Frequency seriations, non-metric multidimensional scaling, and radiocarbon dates suggest that Mound E was constructed and in use several hundred years prior to European contact at the site. The results of this body of research brings new insight into a portion of history of …

Manipulations Of A Memory Interference Paradigm, Lindsay Kyle Crawford Jan 2021

Manipulations Of A Memory Interference Paradigm, Lindsay Kyle Crawford

Electronic Theses and Dissertations

The AB/DE, AC/FG paired associate learning task, which has been utilized in numerous experimental studies, is purported to induce both proactive (PI) and retroactive interference (RI) simultaneously. However, until now, there have not been any studies validating or determining the optimal format of this paradigm. As such, the purpose of this series of experiments was to make manipulations to the task in order to maximize its efficacy. Across the series of experiments implemented herein, we manipulated various aspects of the paradigm (e.g., semantic relatedness of the word pairs, number of trials) driven by theoretical underpinnings of memory interference theory. Experiments …

The Role Of Social Anxiety In Prosocial Behavior Following Exclusion, Hannah Friedman Jan 2021

The Role Of Social Anxiety In Prosocial Behavior Following Exclusion, Hannah Friedman

Electronic Theses and Dissertations

Social anxiety (SA) causes significant distress and impairment in several areas of daily life. Individuals with SA experience increased rates of exclusion and have more difficultly forming meaningful interpersonal relationships. Exclusion is associated with increased SA and motivations for social withdrawal in emerging adulthood. In non-SA individuals, the desire for compensatory social interaction following exclusion often produces prosocial behaviors (e.g., increased effort to help the group). Prosocial behavior levels following exclusion are not uniform, however, as an individual’s response may vary depending on the type of exclusion experienced. Although previous work has observed decreased levels of prosocial behavior in non-SA …


1.5 Generation Korean-American Young Adults' Bilingualism And Their Identity In The U.S., Hanna Kim Jan 2021

1.5 Generation Korean-American Young Adults' Bilingualism And Their Identity In The U.S., Hanna Kim

Electronic Theses and Dissertations

Since the 20th century, particularly post-1965, there has been rapid growth in the Korean-American population in the U.S. The number of 1.5 generation Korean-Americans has also increased. 1.5 generation Korean-Americans can take advantage of learning both languages and cultures in the two countries which can help them become bilingual and bicultural individuals. However, previous studies about the language experience and identity of Korean-Americans have mainly focused on the first or second-generations (Kang, 2013; M. Park, 2005) rather than 1.5 generations. Some of these studies have focused more on children at an early age (E. S. Park, 2005; Zhou, 1997) instead …

Effects Of Nonnative Phonotactic Constraints On The Perception Of Nasal-Initial Consonant Clusters, Msafiri Otonya

Electronic Theses and Dissertations

This study examines the effects of non-native phonotactic constraints on the perception of nasal-initial consonant clusters (NICC), specifically whether native English speakers can perceive NICC as accurately as native Swahili speakers. The ABX task was conducted over Zoom to test L1 English speakers (N=12) and L1 Swahili speakers (N=12). Stimuli with four conditions were used: 1) The stimuli had one of the three nasal sounds (/m/, /n/, and /?/) in word-initial consonant clusters; 2) The stimuli had NICC composed of a nasal sound followed by either a voiced or voiceless consonant; 3) The consonant clusters were composed of sounds that …


Soul Liberation: Black Christian Intellectual Engagement With Black Power, Jemar Tisby Jan 2021

Soul Liberation: Black Christian Intellectual Engagement With Black Power, Jemar Tisby

Electronic Theses and Dissertations

Throughout the Civil Rights movement, Black Christians figured prominently as clergy, leaders, and foot soldiers in the struggle. As a result, the presence of Black Christians during this phase of the Black activism is well-documented by historians. During the Black Power era, however, scholars tend to overlook the ongoing presence and significance of Black Christians in the movement. Soul Liberation corrects this omission by studying Black Christian engagement during the Black Power movement of the 1960s and 1970s.


Epigenetic Regulation In Brevundimonas Subvibrioides And Comparison With The Caulobacter Crescentus Model, Satish Adhikari Jan 2021

Epigenetic Regulation In Brevundimonas Subvibrioides And Comparison With The Caulobacter Crescentus Model, Satish Adhikari

Electronic Theses and Dissertations

Epigenetics is a form of DNA methylation-based gene regulation. The CcrM methyltransferase and transcriptional regulator GcrA, constitute an epigenetic regulatory system well-conserved throughout the Alphaproteobacteria. The regulatory targets of GcrA and CcrM were identified in the Alphaproteobacterium Brevundimonas subvibrioides, and then compared to those of its close relative Caulobacter crescentus. Both these bacteria belong to the same family and inhabit the same environment. Although the regulators themselves are highly conserved, the genes they regulate are vastly different. GcrA directly regulates 204 genes in C. crescentus, and though B. subvibrioides has orthologs to 147 of those genes, only 48 genes retained …

Come As You Are: Islamic Religiousness As A Context For Mental Illness Beliefs And Treatment, Elijah Phoenix Mudryk

Electronic Theses and Dissertations

The United States is home to approximately three million Muslim-Americans, a diverse and growing demographic group that has woven itself into the fabric of American life. Hailing from many regions around the world, Muslims in the U.S. are varied in racial and ethnic backgrounds and not dominated by any particular race or ethnicity. National pride and a strong religious identity are shared aspects among U.S. born Muslims and immigrants alike (Pew, 2018). In addition to the typical challenges of daily life, Muslim-Americans have experienced high levels of religious and ethnic discrimination. Post-9/11, Muslim-Americans suffered a 1600% increase in reported hate …


Acoustic Bessel And Vortex Beams: Forces And Refraction, Xudong Fan Jan 2021

Acoustic Bessel And Vortex Beams: Forces And Refraction, Xudong Fan

Electronic Theses and Dissertations

Non-contact manipulation techniques or tweezers devices are invaluable for applications in physics, chemistry, biology, and engineering. Acoustic tweezers using either standing waves or focused beams have been investigated for more than a few decades with advantages of label-free operation, noninvasiveness, and biocompatibility when compared with the optical, magnetic, and electrical counterparts. Here, a new type of acoustic tweezers (i.e. acoustic tractors) is studied using acoustic Bessel and vortex beams that are able to pull objects against the beam's propagation over centimeter ranges. Stable acoustic tractors require transversely stable trapping in addition to axially negative pulling. Hence, the transverse forces acting …

Through this analysis, I found that federal and state governments reacted to the 1918 flu very quickly, whereas the response to COVID-19 was hindered due to political in-fighting that impeded the bureaucracy and …


Effect Of Chronic Pain On Prospective Memory Performance, Alexander Joseph Kuka Jan 2021

Effect Of Chronic Pain On Prospective Memory Performance, Alexander Joseph Kuka

Electronic Theses and Dissertations

Chronic pain is among the most widespread and disabling conditions worldwide. In the United States, approximately 50 million people suffer from chronic pain, and nearly half that number experience daily chronic pain. Diagnostic testing, treatments, and operations related to chronic pain cost Americans over $600 billion annually. Prospective memory, the process by which people remember to perform an action in the future after a delay, appears to be affected by the experience of pain, especially when a prospective memory task is more cognitively demanding. While self-report studies of individuals with chronic pain suggest that pain adversely affects both their retrospective …

Search For Cpt And Lorentz Invariance Violation In The Muon G-2 Experiment At Fermilab, Meghna Bhattacharya Jan 2021

Search For Cpt And Lorentz Invariance Violation In The Muon G-2 Experiment At Fermilab, Meghna Bhattacharya

Electronic Theses and Dissertations

The Muon g-2 experiment at Fermilab (E989) aims to measure the anomalous magnetic moment of the muon, $a_{\mu}= (g-2)/2$, to a groundbreaking precision of $140$ ppb, obtaining a near four-fold increase in precision over the previous experiment, E821, at the Brookhaven National Laboratory (BNL). The value of $a_{\mu}$ from BNL currently differs from the Standard Model prediction by $\sim 3.7$ standard deviations, suggesting the potential for new physics and therefore, motivating a new experiment.Because the theory predicts this number with high precision, testing the g-factor through experiment provides a stringent test of the SM and can suggest physics beyond the …
