Analyzing Patterns Of Complexity In Pre-University L2 English Writing, Zachary M. Lambert

Theses and Dissertations

The present study involves the creation and analysis of a corpus containing 7747 samples of timed, pre-matriculated L2 English writing from an IEP. The focus of the analysis is on three phrasal complexity measures with time and proficiency as fixed effects, examining their impact on each measure. Results of the analysis suggest that this is true for some phrasal measures, such as nominalizations and attributive adjectives, while others, such as noun-noun phrases, may indicate a lower level of proficiency or lesser allotted writing time. Nominalizations in particular demonstrated a strong relationship with both allotted time and proficiency, further suggesting that …

Spatial Metaphors In Introductory Statements Of Humanities And Stem Disciplines: A Study Of English And Mechanical Engineering Departments, Olalekan T. Adepoju

Publications and Research

Advances in higher education, specifically in science and technology, have engendered a significant shift of interest from a mainly liberal arts curriculum to STEM-related fields of study, creating a rift in the value systems undergirding the two academic domains. One of the ways the disciplinary disparity is institutionally expressed is through the language used in describing the core values of these disciplines, specifically in the introductory statements of departments. Using the lens of spatial metaphor to consider how the language expresses distinct realities that align with the public perceptions of the disciplines, this paper examines the metaphorical framings in the …

A Bayesian Susceptible-Infectious-Hospitalized-Ventilated-Recovered Model To Predict Demand For Covid-19 Inpatient Care In A Large Healthcare System, Stella Coker Watson Self Ph.D., Ms, Rongjie Huang, Shrujan Amin, Joseph Ewing, Caroline Rudisill, Alexander C. Mclain

Faculty Publications

The COVID-19 pandemic has strained healthcare systems in many parts of the United States. During the early months of the pandemic, there was substantial uncertainty about whether the large number of COVID-19 patients requiring hospitalization would exceed healthcare system capacity. This uncertainty created an urgent need to accurately predict the number of COVID-19 patients that would require inpatient and ventilator care at the local level. As the pandemic progressed, many healthcare systems relied on such predictions to prepare for COVID-19 surges and to make decisions regarding staffing, the discontinuation of elective procedures, and the amount of personal protective equipment (PPE) …

Navigating Acculturative Stress: A Guide For Supporting Newcomer Students In California Esl Classrooms, Daniela Lopera Ruiz

Master's Projects and Capstones

Acculturation has been widely studied as a post-migration phenomenon that individuals face when coming in contact with their new recipient culture and environment. The different experiences, tasks, and requirements that newcomers must endure upon arrival may lead to their suffering prolonged periods of discomfort. This moderate, intermediate, or acute feeling of uneasiness is defined as acculturative stress. In it, the continued exposure to stressors such as adjusting to a new culture, rules, behavioral patterns, a second language, finding housing, and obtaining an education and employment can lead to trauma. This field project has been designed to provide educators and allies …

Daily Rounding To Reduce Catheter-Associated Urinary Tract Infections In A Rehabilitation Facility, Folashade Oluwafunmi

Dissertations

Despite national efforts to reduce catheter-associated urinary tract infections (CAUTIs), healthcare facilities continue to report CAUTI events. The project site reported CAUTI rates above local and national benchmarks even though a CAUTI bundle was in use. The purpose of this quantitative quasi-experimental quality improvement project was to determine if the implementation of daily rounding by organizational CAUTI champions, using the Agency for Healthcare Research and Quality (AHRQ) Comprehensive Unitbased Safety Program (CUSP), would impact CAUTI rates among adult residents in a rehabilitation facility in Northern California for four weeks. Lewin's change theory and the IOWA evidence-based practice model were the …

A Structural Perspective On Neutralizing Antibodies To Flaviviruses And Coronaviruses, John Michael Errico

Arts & Sciences Graduate Student Theses and Dissertations

The presence of neutralizing antibodies typically correlates strongly with protection from infection, particularly for RNA viruses; elicitation of neutralizing antibody responses is thus the primary goal of most vaccines, and monoclonal antibodies (mAbs) can be leveraged as potent therapeutics. Thus, understanding the properties of individual antibodies that comprise polyclonal antibody responses and their epitopes is essential for countermeasure design. In this dissertation, I explore the epitopes and functional properties of monoclonal antibodies targeting the structural proteins of two families of RNA viruses, flaviviruses and coronaviruses.Flaviviruses are globally distributed arthropod-borne positive-sense RNA viruses transmitted primarily by either mosquitos or ticks. Symptomatic …

Understanding Individual Cells In Zebrafish Caudal Fin Regeneration (从单细胞视角理解斑马鱼尾鳍再生历程), Yiran Hou

Arts & Sciences Graduate Student Theses and Dissertations

Humans are incapable of complex body structure regeneration. Understanding how other species retain the ability to regenerate can help us to find solutions for improving our regenerative capacities. The zebrafish is an organism that is capable of regenerating multiple organs in its body. Using zebrafish as a model organism, previous studies have identified key processes and illustrated the crucial cell types and genes for regeneration. In caudal fin specifically, blastema formation is a key predictor of successful regeneration. However, a comprehensive molecular understanding of cell type-specific contributions to this process is lacking. In this dissertation, I present our efforts toward …

Making Emotions Trustworthy, Xiaoyu Ke

Arts & Sciences Graduate Student Theses and Dissertations

I investigate ways by which agents can make their emotions more trustworthy from a perspective that’s informed by recent psychological research on the nature of emotion regulation. This dissertation is a collection of three articles, each addressing one type of cases of untrustworthy emotions in a particular context. Chapter one (Developing Appropriate Emotions) concerns emotions that are untrustworthy because they are irrelevant to the moral or epistemic judgements at hand. By situating the problem in the context of a situationist challenge to neo-Aristotelian virtue ethics, I argue that we can address this problem by developing ameliorative abilities such as emotion …

A Synthesis-Based Approach To The Study Of Fe(Ii) Oxidation In Smectites, Robert Joe Kupper Ii

Arts & Sciences Graduate Student Theses and Dissertations

Smectite clay minerals are present in diverse environments on Earth as a major product of silicate weathering. Although smectites are compositionally varied, they almost always incorporate iron. Iron-bearing smectites are an important component of the biogeochemical iron cycle, serving as a major iron fraction in many soils and altered rocks as well as participating in redox reactions within the surrounding environment. Iron incorporates into smectites in the ferric [Fe(III)] form at the modern, oxygenated surface of Earth but clays forming in anoxic settings instead incorporate ferrous iron [Fe(II)]. Owing to their ubiquity at the surface of the modern Earth, the …

Kernel Estimation Of Spot Volatility And Its Application In Volatility Functional Estimation, Bei Wu

Arts & Sciences Graduate Student Theses and Dissertations

It\^o semimartingale models for the dynamics of asset returns have been widely studied in financial econometrics. A key component of the model, spot volatility, plays a crucial role in option pricing, portfolio management, and financial risk assessment. In this dissertation, we consider three problems related to the estimation of spot volatility using high-frequency asset returns. We first revisit the problem of estimating the spot volatility of an It\^o semimartingale using a kernel estimator. We prove a Central Limit Theorem with an optimal convergence rate for a general two-sided kernel under quite mild assumptions, which includes leverage effects and jumps of …

Geometry And Dynamics Of Rolling Systems, Bowei Zhao

Arts & Sciences Graduate Student Theses and Dissertations

Billiard systems, broadly speaking, may be regarded as models of mechanical systems in which rigid parts interact through elastic impulsive collision forces. When it is desired or necessary to account for linear/angular momentum exchange in collisions involving a spherical body, a type of billiard system often referred to as no-slip has been used. Previous work indicated that no-slip billiards resemble non-holonomic systems, specifically, systems consisting of a ball rolling on surface. In prior research, such connections were only observed numerically and were restricted to very special surfaces. In this thesis, it is shown that no-slip billiard and rolling systems are …

Truncated Realized Variations Of Lévy Models: Optimality, Debiasing, And Implementation Approaches, Yuchen Han

Arts & Sciences Graduate Student Theses and Dissertations

Statistical inference for stochastic processes under high-frequency observations has been an active research area in econometrics and financial statistics for over twenty years. In this thesis, we consider some aspects related to the estimation of the volatility of an Itô semimartingale in the presence of Lévy-type jumps, which is of fundamental importance in derivatives pricing evaluation, risk management and portfolio allocation. The main technique we use is the Truncated Realized Variation (TRV) that is both rate- and variance-efficient, in the Cramer-Rao lower bound sense, when jumps are of bounded variation.Motivated by recent results that state that the optimal threshold parameter, …

Using Proteomics To Discover New Connections In The Arabidopsis Circadian Clock, Maria Lynn Sorkin

Arts & Sciences Graduate Student Theses and Dissertations

The plant circadian clock is an endogenous timekeeping mechanism that uses daylength and temperature cycles to synchronize internal physiology with the external environment. Much of our understanding of the clock in the model plant Arabidopsis thaliana comes from genetic approaches. In this thesis, I use affinity purification coupled with mass spectrometry (APMS) to identify protein-protein interactions for core clock components on a proteomic scale. I developed and optimized a protocol to perform APMS on a core set of circadian clock proteins: CIRCADIAN CLOCK ASSOCIATED 1 (CCA1), LATE ELONGATED HYPOCOTYL (LHY), PSEUDORESPONSE REGULATOR 5 (PRR5), PRR7, PRR9, TIMING OF CAB 1 …

Local Spectroscopy Data Infrastructure: Solid State Nmr Crystallography With Experiment, First-Principal Analysis And Machine Learning, He Sun

Arts & Sciences Graduate Student Theses and Dissertations

Solid-state magnetic resonance (SSNMR) spectroscopy is a powerful tool for obtaining precise information about the local bonding and morphology of materials. The detailed local structure of crystalline materials cannot be easily solved by traditional experimental methods such as X-ray diffraction (XRD). SSNMR combined with first principal calculation methods such as density functional theory (DFT) can be of great use in this research area. The methodology that is called “NMR crystallography” today has been widely applied to the determination of a wide range of solid materials with an increasing amount of computationally simulated NMR spectra. The construction of a well-established computational …

Characterization Of Pulmonary Vascular Remodeling And Microrna-126-Targets In Copd-Pulmonary Hypertension, Khushboo Goel, Nicholas Egersdorf, Amar Gill, Danting Cao, Scott D Collum, Soma S Jyothula, Howard J Huang, Maor Sauler, Patty J Lee, Susan Majka, Harry Karmouty-Quintana, Irina Petrache

Faculty, Staff and Student Publications

BACKGROUND: Despite causing increased morbidity and mortality, pulmonary hypertension (PH) in chronic obstructive pulmonary disease (COPD) patients (COPD-PH) lacks treatment, due to incomplete understanding of its pathogenesis. Hypertrophy of pulmonary arterial walls and pruning of the microvasculature with loss of capillary beds are known features of pulmonary vascular remodeling in COPD. The remodeling features of pulmonary medium- and smaller vessels in COPD-PH lungs are less well described and may be linked to maladaptation of endothelial cells to chronic cigarette smoking (CS). MicroRNA-126 (miR126), a master regulator of endothelial cell fate, has divergent functions that are vessel-size specific, supporting the survival …

Effectiveness Of Community Development Organizations In The St. Louis Metropolitan Area, Kyle Pitzer

Brown School Graduate Student Theses and Dissertations

Concentrated poverty has been a core issue in urban America for close to half of a century. The consequences of living in these neighborhoods are also dire. These "neighborhood effects" are defined as the effects of living in concentrated poverty over and above individual circumstances, which have been tied to a number of important life outcomes. One approach to addressing these issues is community development, and perhaps the most salient vehicle of community development is the community development corporation (CDC). This current study sought to address three aims: 1), understand the effects of CDCs on population-level outcomes; 2), understand the …
