Andrew B. Arnold's Fueling The Gilded Age: Railroads, Miners, And Disorder In Pennsylvania Coal Country, Laura Phillips Sawyer

Scholarly Works

Andrew Arnold’s Fueling the Gilded Age explores the struggles for managerial control and economic power that erupted among coal miners, coal operators, and railroad executives in central Pennsylvania between 1872 and 1902. Rather than presenting an unassailable triumph of the railroads’ interests over labor, Arnold argues that the “coal industry defied order” (p. 3) and laborers exhibited “unexpected agency ” (p. 4, emphasis in original) by thwarting the plans of railroad executives to impose managerial capitalism from the top down. Instead, wage earners “refused to accept their designated fate as commodities” (p. 222) and thereby exerted influence on the institutional …

A Structural Equation Model Of The Influence Of Personal, Behavioral, And Environmental Factors On The Writing Performance Of First-Year Students At A Selected Michigan Community College, Thula I. Norton Lambert

Dissertations

Problem.

While previous writing performance studies have examined a range of motivational variables such as self-efficacy or writing apprehension, certain contextual variables and variables related to current writing pedagogy and practice have not been included, which has resulted in gaps in the research literature.

Method.

A non-experimental, correlational, cross-sectional, ex post facto, survey research design was used to examine the personal, behavioral, and environmental factors that had been identified as being of potential influence to students’ writing performance. A census was conducted among the 233 students enrolled in English Composition on the two campuses of a small two-year college in …

The Function Of 'Hope' As A Lexical And Theological Keyword In The Psalter: A Structural-Theological Study Of Five Psalms (Pss 42-43, 52, 62, 69, 71) Within Their Final Shape Context (Pss 42-72), Christine Maria Vetne

Dissertations

The shape and message of the Psalter has been of central interest for many Old Testament scholars during the last thirty years. At the core of shape scholarship stands the issue of hope. Often this is related to what is commonly considered a major hope-shift in the Psalter, which moves its focus from hoping in the Davidic covenant (Books I-III) to hoping in God (Books IV-V). However, when considering the shape and message of Book II, there is evidence that these two hopes coexist, side by side, as also seen in the introduction to the Psalter (Ps 2).

This dissertation …

A Study On The Influence Of Philosophical Presuppositions Relating To The Notion Of The God-Human Relation Upon The Interpretation Of Exodus, Tiago Arrais

Dissertations

Abstract

No exegesis or act of interpretation is presuppositionless. Accordingly, this study addresses the question of the influence of philosophical presuppositions upon the interpretation of the God-human relation in Exodus.

Chapter 1 provides a brief introduction to why such analysis is necessary. The chapter explores the neglected issue of presuppositions in exegesis and why Exodus is an appropriate platform upon which to evaluate them. This introductory chapter also presents the purpose and methodological approach of this study, namely, the descriptive analysis of the text.

Chapter 2 addresses the philosophical issues behind the conception of the God-human relation, namely the notion …

Electrical, Computer, and Biomedical Engineering Faculty Publications

Spoofing is the common term used for describing the intentional broadcasting of false radio frequency signals intended to disrupt and mislead systems that depend on accurate position, navigation, and timing information provided by Global Navigation Satellite Systems (GNSS). Spoofing is an increasingly recognized threat garnering increased interest from researchers and users, both military and civilian. This paper presents a GNSS spoof detection algorithm that exploits the geometric distribution of a horizontal array of GNSS receiver antennae and the geometric configuration of visible navigation satellites. Using a Neyman-Pearson hypothesis testing formulation, a spatial correlation test is developed that can accurately and …

Children With Sli Exhibit Delays Resolving Ambiguous Reference, Julie M. Estis, Brenda L. Beverly

University Faculty and Staff Publications

Fast mapping weaknesses in children with specific language impairment (SLI) may be explained by differences in disambiguation, mapping an unknown word to an unnamed object. The impact of language ability and linguistic stimulus on disambiguation was investigated. Sixteen children with SLI (8 preschool, 8 school-age) and sixteen typically developing age-matched children selected referents given familiar and unfamiliar object pairs in three ambiguous conditions: phonologically distinct word (PD), phonologically similar word (PS), no word (NW). Preschoolers with SLI did not disambiguate, unlike typically developing age-matched participants, who consistently selected unfamiliar objects given PD. School-age children with SLI disambiguated given PD. Delays …

Development Of 3-D Shear Wave Models Using A Multi-Objective Optimization Scheme, Lennox Emmanuel Thompson

Open Access Theses & Dissertations

Evidence of geologic activity still occurring in Rio Grande Rift (RGR) includes quaternary faulting, seismicity, and widening at a small rate. We map the crustal thickness and seismic velocity ratio to create crustal model cross sections that highlights the regional extension of the Southern Rio Grande Rift (SRGR). Specifically, we compute receiver functions and receiver function stacks for 147 USArray and previously collected data, and interpolate the crustal and velocity results using a kriging interpolation scheme. By incorporating gravity, magnetics, receiver functions, velocity models, and the interpretation of seismic reflection/refraction data, we produce a constrained crustal model that characterizes the …

Classroom Labels That Young Children Can Use: Enhancing Biliteracy Development In A Dual Language Classroom, Irasema Salinas-González, Iliana Alanis, María G. Arreguín-Anderson

Human Development and School Services Faculty Publications

This article focuses on biliteracy development of English and Spanish through the practical strategy of systematically labeling the classroom within the context of daily classroom activities and providing children with various opportunities to use the words throughout the day. Using the foundational work related to classroom labels from Pinnell and Fountas (1998, 2010), the authors adopt a definition indicating that a label consists of one or a few words on a card placed on or below an object or a spot in the classroom. Providing young dual language learners opportunities to use language in both the spoken and written form …

Technical Note: Phantom Study To Evaluate The Dose And Image Quality Effects Of A Computed Tomography Organ-Based Tube Current Modulation Technique, Diksha Gandhi, Dominic J. Crotty, Grant M. Stevens, Taly Gilat Schmidt

Biomedical Engineering Faculty Research and Publications

Purpose

This technical note quantifies the dose and image quality performance of a clinically available organ-dose-based tube current modulation (ODM) technique, using experimental and simulation phantom studies. The investigated ODM implementation reduces the tube current for the anterior source positions, without increasing current for posterior positions, although such an approach was also evaluated for comparison.

Methods

Axial CT scans at 120 kV were performed on head and chest phantoms on an ODM-equipped scanner (Optima CT660, GE Healthcare, Chalfont St. Giles, England). Dosimeters quantified dose to breast, lung, heart, spine, eye lens, and brain regions for ODM and 3D-modulation (SmartmA) settings. …

Critical Changes In Cortical Neuronal Interactions In Anesthetized And Awake Rats, Anthony G. Hudetz, Jeannette A. Vizuete, Siveshigan Pillay, Kristina M. Ropella

Biomedical Engineering Faculty Research and Publications

Background: Neuronal interactions are fundamental for information processing, cognition, and consciousness. Anesthetics reduce spontaneous cortical activity; however, neuronal reactivity to sensory stimuli is often preserved or augmented. How sensory stimulus–related neuronal interactions change under anesthesia has not been elucidated. In this study, the authors investigated the visual stimulus–related cortical neuronal interactions during stepwise emergence from desflurane anesthesia.

Methods: Parallel spike trains were recorded with 64-contact extracellular microelectrode arrays from the primary visual cortex of chronically instrumented, unrestrained rats (N = 6) at 8, 6, 4, and 2% desflurane anesthesia and wakefulness. Light flashes were delivered to the retina …

Acculturation, Psychological Distress, And Smoking In Latinos Living With Hiv/Aids, Jessica Armendariz

Open Access Theses & Dissertations

In the United States smoking cigarettes is the leading cause of preventable death, and smoking is of particular health concern among people living with HIV. Depression has been consistently linked to smoking in the literature, and data indicate that acculturation to the U.S. is associated with increased depression among Latinos.

This study examined if acculturation moderates the impact of depression on smoking behavior among Latinos living with HIV through the mediating effect of social support. The results may extend to the sociopsychological construct of culture. We studied 300 Latinos who live with HIV on the U.S./Mexico border.

Results demonstrated there …

Challenges In Assessing College Students' Conception Of Duality: The Case Of Infinity, Grace Olutayo Babarinsa-Ochiedike

Open Access Theses & Dissertations

Interpreting students' views of infinity posits a challenge for researchers due to the dynamic nature of the conception. There is diversity and variation among students' process-object perceptions. The fluctuations between studentsâ?? views however reveal an undeveloped duality conception. This study examined college students' conception of duality in understanding and representing infinity with the intent to design strategies that could guide researchers in categorizing students' views of infinity into different levels.

Data for the study were collected from N=238 college students enrolled in Calculus sequence courses (Pre-Calculus, Calculus I through Calculus III) at one of the southwestern universities in the U.S. …

Short-Term Forecasting Analysis Of Municipal Water Demand In El Paso, Texas, Alejandro Ceballos

Development Of Rigorous Electromagnetic Simulation Tools For Anisotropic Structures, Jose Luis Enriquez

Open Access Theses & Dissertations

Many times, mankind's creative nature has pushed the envelope beyond what was deemed physically possible at the time. People have engineered ways for us to fly, communicate across the globe in seconds, landed on the moon, and more recently discovered ways to make an object invisible. Unfortunately, there are times that this creativeness is hindered by funding, access to required tools or a combination of both. While this work cannot provide funding, it does provide a tool that one could use to model and simulate a variety of media. The media can vary from devices already being implemented to more …

Simulations Of The Effects Of Temperature And Plasma In Carbide Processing, Alejandro Garcia

Open Access Theses & Dissertations

The transient surface temperature of particles within a packed bed was simulated to enable ultimately the prediction of plasma-surface reactions at ultrahigh temperatures. The motivation for the present study was along two fronts - the reactive infusion of liquid alloys at ultrahigh temperatures to process metal matrix or ceramic matrix composites and the plasma processing of materials to spike the surface temperatures to enable the formation of protective oxidizing scales on ultrahigh ceramic composites. The transient temperature simulations determined that a graphite crucible containing B4C spherical particles heated from 298 to 2128 K and 2504 K occurred in about 900 …

Electrical Stimulation Uses Sodium Channel Dependent Depolarization To Produce Exocytotic-Like Dopamine Release And Rotational Behavior In Vivo, Alice Elaine Hernandez

Open Access Theses & Dissertations

The goal of this project was to establish Electrical Stimulation (ES) in combination with In Vivo Intracerebral Microdialysis (IVMCD) as a methodology to evoke exocytotic-like dopamine (DA) release. To provide evidence that ES mimics action potential-mediated DA exocytosis, we hypothesized that ES produces depolarization of the membrane potential that is dependent upon sodium (Na+) -channels to produce DA release concomitantly with rotational behavior. To test this, rats received electrode and cannulae implants along the medial forebrain bundle, which contains the DAergic nigrostriatal pathway, and a microdialysis probe at the striatum to undergo IVMCD testing. To begin, steady baseline DA levels …

Computational Search For Novel Magnetic Clusters With Large Magnetic Anisotropy Energy, Nabil Md Rakinul Hoque

Open Access Theses & Dissertations

The clusters of transition metal atoms often show high spin moments but generally are reactive with the environment. Passivation of the surface atoms can lead to more stable clusters. We have explored one such avenue for passivation in this work. We picked the As@Ni12@As20 cluster which in the neutral state has a magnetic moment of 3 μB. We doped this cluster with various numbers of Mn atoms by substituting Ni atoms. The substitutional doping leads to spin moments located on the Mn atoms. The doping leads to symmetry breaking and as a consequence the number of structural isomers and spin …

Late Miocene-Quaternary Fault Evolution And Interaction In The Southern California Inner Continental Borderland, Christopher C. Sorlien, Jonathan T. Bennett, Marie-Helene Cormier, Brian A. Campbell, Craig Nicholson, Robert L. Bauer

Graduate School of Oceanography Faculty Publications

Changing conditions along plate boundaries are thought to result in the reactivation of preexisting structures. The offshore southern California Borderland has undergone dramatic adjustments as conditions changed from subduction tectonics to transform tectonics, including major Miocene oblique extension, followed by transpressional fault reactivation. However, consensus is still lacking about stratigraphic age models, fault geometry, and slip history for the near-offshore area between southern Los Angeles and San Diego (California, USA). We interpret an extensive data set of seismic reflection, bathymetric, and stratigraphic data from that area to determine the three-dimensional geometry and kinematic evolution of the faults and folds and …

Memory, State Violence, And Revolution: Mexico's Dirty War In Ciudad Juárez, Vanessa Claire Johnson

Open Access Theses & Dissertations

After the uprising that took place in Madera, Chihuahua on September 23, 1965, the first armed challenge to the state since the Mexican Revolution, the north became a region of historical significance for understanding the subsequent "Dirty War" that spanned from the late 1960s to the early 1980s. Ciudad Juárez was a key locale in which a wide variety of revolutionary groups conducted both open and clandestine activities. Attempting to rouse the masses, a dedicated few organized protests, counter-meetings, popular assemblies, and launched a prepa popular to reorganize and democratize education. The Mexican state responded to these events with repression, …

The Window To The Bilingual Mind: Eye Movements Reveal Psycholinguistic Grain Unit Sizes Of Bilingual Spoken Word Recognition, Yu-Cheng Lin

Open Access Theses & Dissertations

Although there are common phonological units across different languages, previous studies have shown that individual differences of language proficiency affect sound unit preferences in monolingual and bilingual speakers. The cross-language lexical activation of phonological representations in bilingual minds can provide a great opportunity for testing hypotheses about how this key factor modulates the cross-linguistic phonological transfer across languages. In this study, I used the eye-tracking technique and quantitative methods (i.e., growth curve analysis and multilevel regression) to examine how individual differences in language proficiency affect cross-language phonological unit size transfer in Chinese-English bilinguals. Participants heard a spoken word and were …

Open Access Theses & Dissertations

Introduction: Structural degradation, moisture levels, and building failures can influence poor indoor air quality and create a good environment for bioaerosols. People spend much of their time indoors and can potentially be exposed to these bioaerosols. Several studies have correlated exposures to high concentrations of bioaerosols to various health problems, severe allergies, asthma, or other respiratory illness. Objectives: The objectives of this study are to describe bioaerosol concentrations, meteorological factors, and health outcomes during the summer and fall seasons; characterize bioaerosols (bacteria and fungi) collected in low-income communities; compare bioaerosol concentrations by season; compare meteorological factors to bioaerosol concentrations by …

Rural Clinicians’ Perceived Ethical Dilemmas: Relationships With Clinician Well-Being And Burnout, Amithea M. Love

Antioch University Dissertations & Theses

Mental health clinicians are bound by professional ethics codes that are intended to ensure beneficence toward clients. When clinicians reside in rural areas, ethical dilemmas result from the distinct nature of rural life and clinical practice. Despite extant literature on the ethical dilemmas of rural practice, little research has examined the effect of ethical dilemmas on the social-emotional functioning of clinicians. In response to this need, the study investigated the relationships of frequency of and discomfort from ethical dilemmas on clinician social-emotional functioning. Participants were rural and small town clinicians (N = 60) between ages 24-65 and primarily Caucasian (83.3%), …

Effects Of Presenting Normative Alcohol Data On Perceptions Of College Drinking Behavior, Cullen Patrick Hardy

Antioch University Dissertations & Theses

Alcohol abuse, often in the form of binge drinking, is a problem that every college campus faces. Many researchers suggest that students believe that their peers drink more alcohol than is actually true, and use such a perception as a justification to drink more alcohol than should be consumed (Perkins, Haines, & Rice, 2005). The purpose of this study is to understand whether presenting normative information on drinking behavior among college students in two different ways (focus on heavy drinking or focus on abstinence) has an effect on the perceptions of drinking behavior.
