Structural Controls On The Distribution Of Groundwater In Southern Sinai, Egypt: Constraints From Geophysical And Remote Sensing Observations, Lamees Mohamed

Dissertations

An integrated (Very Low Frequency [VLF] electromagnetic, magnetic, remote sensing, field, and Geographic Information System [GIS]) study was conducted over the basement complex in Southern Sinai (Feiran watershed) for a better understanding of the structural controls on the groundwater flow. The increase in satellite-based radar backscattering values following a large precipitation event (date: 17, 18 Jan 2010; amount: 34 mm) was used to identify water-bearing features, here interpreted as preferred pathways for surface water infiltration. Findings include: (1) The distribution of the water bearing features (conductive features) correspond to that of fractures, faults, shear zones, dike swarms, and wadi networks; …

Using Stories As The Landscape Of Writing: A Case Study Of Mentor Texts In The Elementary Classroom, Christine Mcdowell

Dissertations

In this dissertation, I investigate the way in which mentor texts are defined and implemented by four elementary classroom teachers within one school district, and how this mode of instruction allows for an increase in teacher autonomy while still addressing Common Core State Standards. This project focuses on each participant as they share a common goal in writing instruction while maintaining their teaching identity and curricular freedom.

One goal of this study is to provide the educational theory that supports mentor text instruction that is missing from the movement. Many teaching guides exist that explain the concept of mentor texts, …

Secondary Mathematics Teachers’ Attitudes And Beliefs Toward Statistics: Developing An Initial Profile, Christina M. Zumbrun

Dissertations

Over the last several decades, mathematics education researchers have given increased attention to students’ and teachers’ attitudes and beliefs toward mathematics and statistics, but no work has been done that examines practicing secondary mathematics teachers’ (SMTs’) attitudes and beliefs towards statistics in light of the GAISE framework and the Common Core State Standards for Mathematics (CCSSM). This study begins to address this gap in the research by creating the Teacher Attitude and Beliefs toward Statistics Survey (TABSS), a synthesis of items taken from the Survey of Attitudes Toward Statistics (Schau, 2003), the Statistics Course Attitude Scale and newly developed items …

A Study Of Conceptual And Language Issues Surrounding Weight, Weightlessness, And Free Fall: Textbook Analysis, Instructional Design, And Assessment, Rex Taibu

Dissertations

Science education is an interdisciplinary field that has developed from and continues to rely on research in the fields of cognitive science, philosophy, psychology, sociology and history. This clearly reflects that learning and teaching can be studied from multiple perspectives. Despite these wide ranging roots, contemporary science education by and large is not informed by the work of research on linguistics, and in particular, the role of language in mediating conceptual understanding. The term “weight” has multiple meanings in both science and everyday language, and this unfortunately creates inherent difficulties for teaching and learning. The present study addresses a need …

Differential Effects Of Methylenedioxypyrovalerone (Mdpv) And Mephedrone In Rats Trained To Discriminate Mdma Or A D-Amphetamine+Mdma Mixture, Eric Louis Harvey

Masters Theses

Recent reports on the abuse of novel synthetic cathinone derivatives call attention to serious public health risks of these substances. In response to this concern, a growing body of preclinical research has characterized the psychopharmacology of these substances, particularly mephedrone (MEPH) or methylenedioxypyrovalerone (MDPV), noting their similarities to MDMA and cocaine. The present study employed drug discrimination methodology to assess the discriminative stimulus effects of MEPH and MDPV in male Sprague-Dawley rats trained to discriminate 1.5 mg/kg 3,4 methylenedioxymethamphetamine (MDMA) or a mixture of 1.5 mg/kg MDMA and 0.5 mg/kg d-amphetamine (MDMA+AMPH). After establishing dose response functions with each training …

Spatial Patterns Of Drought Persistence In Xinjiang (A.R), China, Guzhaliayi Sataer

Masters Theses

Droughts have become one of the crucial hazards affecting Xinjiang, Northwest China, the biggest agricultural province and an important area for the grazing husbandry industry in China. Investigations about droughts in Xinjiang have been conducted from various perspectives by previous researchers. However, there are very few studies that focus on drought persistence and seasonal drought frequency. These issues are particularly important as they influence water resource management and forecasting, crop yields, agricultural development and energy consumption. Seasonal drought persistence describes how well drought conditions persist from one season to next season and is expressed as probability of persistence. In this …

Anomalous Thermal Indicators From Authigenic Minerals In Upper Paleozoic Strata Of The Michigan Basin, Kyle Cox

Masters Theses

Indications of anomalous paleo-temperatures exist in strata of the Michigan basin, USA. The thermal history of the basin was investigated through identification and analysis of authigenic components in two Upper Paleozoic strata, the Devonian Dundee Formation and Mississippian Marshall Sandstone. Formation conditions for diagenetic phases in both units were estimated through a variety of means and compared to conditions expected for a simple burial model. Authigenic clays identified in the Marshall via X-ray diffraction are expected to have formed at temperatures above what would have been produced by burial alone. Stable isotope and fluid inclusion analysis indicate the same for …

Thermal History Of The Michigan Basin: Results From Thermal Maturation Data And Geodynamic Modelling, Kirk A. Wagenvelt

Masters Theses

Thermal cooling, crustal convection, high temperature fluid advection, and 1.0 Km of eroded overburden are required to explain thermal maturation observations in the Michigan Basin. Observed tectonic subsidence in central Michigan follows an exponential decay indicative of thermal cooling following an anomalous heating event. Crustal convection is responsible for episodes of rapid subsidence coincident with the late Paleozoic Appalachian orogeny. Fluid advection through dilated faults reactivated by the Alleghanian orogeny brought hot fluids (as much as 255⁰ C) to the surface and impacted thermal maturation of organic matter in sediments. Models require 1.0 Km of eroded overburden to model thermal …

Performance Analysis Of Magnetic Indoor Local Positioning System, Kyle Wroble

Masters Theses

As of the writing of this paper, there is no standard technique for implementing Indoor Position Systems (IPS) in one building or another, as each technique has its own advantages and drawbacks. The best IPS implementations often employ the use of multiple techniques within a building in order to maximize precision. This paper explores the most popular IPS techniques in use today, and highlights their strengths and weaknesses. After analyzing the pros and cons of each approach, it becomes clear that magnetic positioning is a useful tool for creating an accurate, reliable positioning system. Throughout this paper, the feasibility of …

Lnfluences Lmpacting The Development Of Entry-Level Master's Athletic Training Programs, Jennifer E. Deranek

Dissertations

Athletic training is an allied health profession in which individuals receive education in prevention, emergency care, clinical diagnoses, therapeutic intervention and rehabilitation for injuries and medical conditions. Currently, the route for an individual to become a certified athletic trainer is to graduate from an institution accredited by the Commission on Accreditation of Athletic Training Education (CAATE). Most commonly, entry-level education for athletic trainers is gained at the 331 institutions that host a bachelor’s level professional program. However, there is a recent desire to change the educational requirements and to require a professional master’s degree. If the degree change would occur, …

Formant Frequency Transitions In The Fluent Speech Of Adults Who Do And Do Not Stutter: Testing The Over-Reliance On Feedback Hypothesis, Kaitlin Arnold

Masters Theses

A recent theory proposed by Civier and colleagues (Civer et al. 2010; Civer et al. 2013) developed a model of stuttering that implicates a faulty feedforward control system. The hypothesis suggests that stuttering results from relying too heavily on sensory feedback to guide speech movements. An overreliance on sensory feedback would result in subtle anomalies in fluent speech (such as slowed articulatory transitions) as well as overt stuttering behaviors (such as sound repetitions). The present study tested this general hypothesis by comparing articulatory transition rates of adults who do and do not stutter across casual and fast speech rates. Participants …

Effects Of Altering Motivation In Pigeons Performing A Titrating-Delayed-Matching-To-Sample Task, Zachary J. Zimmermann

Masters Theses

In order to better understand the role motivating operations (MOs) serve in preceding and evoking behavior, it is useful to examine the effects of whether manipulating motivation can influence performance on tasks with known behavioral outcomes. It is well established that altered stimulus control is responsible for changes in responding on tasks of generalization and discrimination. Therefore, if stimulus control could be influenced by MOs, then perhaps stimulus discriminations could be improved by manipulating the relevant MO. To this end, the effects of altering motivation via food deprivation were examined in pigeons using a titrating-delayed-matching-to-sample task. Additional pharmacological variables (i.e., …

Microbial Community Analysis From Petroleum-Contaminated Sediments With High Magnetic Susceptibility, Anja E. Williams

Masters Theses

Microbial biodegradation is an increasingly incorporated method of hydrocarbon mineralization during oil spill cleanup. To monitor biodegradation, magnetic susceptibility (MS) is a geophysical tool that detects changes in sediments’ magnetism, possibly caused by microbial activity, for example by anaerobic iron reduction that can induce magnetite formation. Furthermore, the high input of carbon from an oil spill makes other required nutrients, like nitrogen, limiting. The first study goal was to characterize the microbial communities present at high levels of MS with 16S rRNA gene clone libraries at the petroleum-contaminated site in Bemidji, Minnesota. Sequences with high similarity to known iron-reducers were …

The Problem Of Nomological Impossibility For Epistemic Structural Realism, Patrick Manzanares

The Hilltop Review

The philosophical view known as Epistemic Structural Realism appeals to the concept of ‘structure’ in order to defend a version of Scientific Realism that nevertheless respects historical considerations of ontological discontinuity between successive scientific theories. It seems that the structures of some scientific theories are only continuous with the structures of successor theories when the former are characterized as nomologically impossible idealizations of the latter, since this continuity involves allowing some quantity in the formal structure of the successor theory to tend towards some physically unrealizable limit. But if this is the case, then the earlier theory cannot be physically …

Legal And Ethical Considerations For Social Media Hiring Practices In The Workplace, Andrew S. Hazelton, Ashley Terhorst

The Hilltop Review

Social media has certainly evolved and continues to do so with each new day. Social media in its infancy was not as widespread in the personal lives of people, let alone in the workplace. In the following years since its inception, social media has captured a significant amount of time of individuals in every aspect of their lives. However, with this advancement also comes possible conflict in how companies and departments within a university or college setting conduct background checks. Social media makes public profiles an easy click away and many potential job seekers may not see the problems that …

The History Of Punishment: What Works For State Crime?, Jennifer Marson

The Hilltop Review

The punishment of criminal acts is usually justified utilizing retribution, deterrence, rehabilitation and incapacitation (societal protection). These justifications are often utilized for traditional street crimes such as burglary, assault, and theft. However, state crimes require that punishment be looked at through a different lens, and it is advocated the restorative justice apparatuses potentially offer the best solutions at administering punishment for those who commit state crime.

Functional Analysis Of Gambling, Mack S. Costello

Dissertations

Given high rates of gambling and the growing population of disordered gamblers, there is a need to develop assessment strategies with improved treatment validity. More specifically, assessment strategies are needed that identify the controlling variables for disordered gambling and, thus, provide guidance in the selection of treatment and prevention strategies. This study sought to develop a functional analysis for gambling by utilizing a simulated gambling environment in which contextual variables hypothesized to be causally linked to disordered gambling could be systematically manipulated. Seven experienced gamblers participated in the multi-element, single-subject experimental study. Participants who endorsed at least some problems from …

Why Abstain? Trends In And Origins Of Indifference And Estrangement In The United States, 1968-2012, Christopher R. Keeler

Masters Theses

Abstention rates have remained quite high in the United States for the last several decades. This thesis explores the trends in and origins of the nonvoters from 1968 to 2012 using a statistical model of abstention in presidential elections. The objective is to determine why nonvoters have chosen to abstain and who are they?

Using data from the American National Elections Studies, four groups of nonvoters are identified – voters who are both alienated and indifferent, voters who are neither alienated nor indifference, voters who are only alienated, and voters who are only indifferent. The two groups exclusively analyzed are …

Are There Shared Characteristics Among Children With Autism Who Develop Speech While Training With The Picture Exchange Communication System?, Katherine Neidhart

Honors Theses

It is clear in the literature that there are many factors that may contribute the development of speech as a possible outcome of training with the Picture Exchange Communication System (PECS). Research has indicated a need for more data on the characteristics and skills of children with autism that may contribute to their success while using PECS, and the possible development of speech while receiving PECS training.

This study sought to identify common characteristics and skills of children with autism that acquired speech while receiving PECS training through creating an inventory of demographics, pre-requisite skills, and other characteristics of children …

This dissertation is comprised of three studies centered on addressing factors that influence stroke knowledge and decision-making during the acute stroke emergency in both general and Hispanic populations. The first study provided data on patterns of explicit stroke knowledge in a sample of 94 Hispanic subjects. This study assessed relationships between stroke knowledge (Stroke Action Test; STAT; Billings-Gagliardi & Mazor, 2005) and subjects’ typical language use (Short Acculturation Scale for Hispanics; Marín, Sabogal, VanOss Marín, Otero-Sabogal, Pérez-Stable, 1987). No relationship was found between language use (Spanish/English) and stroke symptom knowledge. Contrastingly, STAT scores were found to …

Integrating Formative Assessment Into Physics Instruction: The Effect Of Formative Vs. Summative Assessment On Student Physics Learning And Attitudes, Chaiphat Plybour

Dissertations

Of many instructional strategies used to improve teaching and learning in science, formative assessment is potentially one of the most effective. A central feature is timely feedback during learning, giving students the opportunity to benefit and improve while also enabling teachers to adjust instruction to learner needs. By contrast, conventional assessment tends to be mostly summative, assigning point scores, grading and ranking students, and providing extrinsic motivation. For maximum effectiveness in enhancing learning, formative assessment should be designed into instruction from the start rather than being an add-on. This project comprised development, teaching, and research aspects. Two physics topic modules, …

Three Essays On Racial Wage Differentials In South Africa, Ochas Kashinge Pupwe

Dissertations

Wage gaps amongst the different racial groups in South Africa, have remained high post-apartheid. With the enactment and implementation of several empowerment programs aiming at reversing racial marginalization, it is puzzling to see the persistent wage gaps between the white minority and non-white majority. This dissertation seeks to ascertain factors that may account for the persistent wage gap.

The first essay tests for the presence of over-education and its effects on wage determination amongst South Africa’s racial demographic groups. The results indicate that whites were over-educated whilst marginalized populations exhibited significant levels of under-education in 1991 and 2011 and hence …
