Theses and Dissertations

The purpose of the study was to compare students' achievements, perceptions and evaluations of fully online and web-enhanced courses taken at a technical college in South Texas in order to determine if students achievement, perceptions, and evaluations of course design was better in one modality over the other. The study collected information on students regarding learning experiences in 21 fully online and 12 web-enhanced face-to-face core courses common to all programs of study. These courses were taught in both delivery modes, meaning that the same instructor taught the same course, with identical resources and assignments in both online and the …

Ue Based Performance Evaluation Of 4g Lte Network, Hazza Saif Saeed Alshamisi

Theses and Dissertations

In the past ten years, we have witnessed an increase in demand for mobile services as we have come to depend more and more on mobile phones as an indispensable part of everyday life. And not merely for making phone calls or sending text messages, but also for services such as games, mobile banking, streaming videos and making video calls. These mobile applications consume far more data than simple voice calls. Reflecting what an end user experiences when using a mobile device is an aspect that has not yet been properly catered for. The LTENetScan framework introduced a novel method …

Discrimination Training To Produce Emergent Relations Of Pre-Algebraic Math Skills, Jeanine Rinda Tanz

Theses and Dissertations

Individuals diagnosed with Autism Spectrum Disorder (ASD) often have deficits with respect to generalization of skills. Procedures designed to induce stimulus equivalence have been shown to promote generalization. This study used a modified multiple probe design with an embedded multiple schedule to: (a) compare one-to-many (OTM) and many-to-one (MTO) training structures to determine which structure results in more positive equivalence outcomes when all variables are held constant, and (b) determine the extent to which children with ASD demonstrate stimulus equivalence and stimulus class mergers when using educationally relevant stimuli. Four children with ASD were taught two classes of stimuli (Class …

Effect Of Industry Clusters And Commodity Flow Characteristics On The Selection Of Freight Transportation Modes In The United States With Advanced Econometric Approaches, Taleb Eissa Ali Eissa

Theses and Dissertations

Mode choice is an important strategic decision for shippers to carry commodities efficiently. Freight mode-choice is an important activity to develop a successful freight transportation business in the private sector and to plan for economically consistent freight transportation infrastructures in the public sector. Freight activities result from the complex interactions between different economic agents, but these relationships are commonly relaxed to account for three major agents: shippers, carriers and receivers. Furthermore, the behavior of freight choice is commonly not concentrated in one agent, but rather is divided jointly over multiple individuals and firms in a logistics process, each component of …

Capture Zone Analysis Of A Wellfield To Assess Contaminant Transport, Prince Kojo Oware

Theses and Dissertations

Radium is a common contaminant to the deep Cambrian- Ordovician aquifer in northern Illinois. Deep groundwater aquifers are used as fresh water resource in many parts of the world. Due to overuse, increase in salinity, natural and human-driven contamination, sustainability of these aquifer systems is uncertain. The purpose of this study is to better understand the groundwater flow system in deep bedrock aquifers in northern Illinois, and its control on the radium contamination in Rochelle’s Public Water Supply Wells (PWSW). We have tested two hypotheses: (1) the Radium (Ra) transport is driven by large pumping centers that interrupt groundwater flow …

The Role Of Religious Reformist Discourse In Regime Resilience In Iran, Fatemeh Jamali

Theses and Dissertations

Since the Islamic Revolution in 1979, Iran has been seen as the primary bastion of radical Shi‘a Islam and a force which fosters the Middle East instability. The Iranian regime has often been labeled as a theocracy, which often overshadowed the attention to nuances about its polity and its mechanisms of survival. The main purpose of this thesis is to shed light on the political system of Iran and its survival mechanism while situating it in the hybrid regime category. Hybrid regime framework is especially useful since it allows us to better understand the resilience of the hybrid political structure …

Hydrogeologic Characteristics And Groundwater Sustainability Of A Deep Bedrock Aquifer System In Illinois, Luis Martinez

Theses and Dissertations

Population growth and climate change has made groundwater an increasingly important freshwater resource. This study uses MODFLOW to estimate sustainable yield of a deep St. Peter Aquifer in Bloomington, IL. The city of Bloomington has installed two high capacity wells into the St. Peter Sandstone to meet its growing water demands. The St. Peter Aquifer is confined, receiving almost no modern recharge and is experiencing overexploitation in parts of Northern Illinois. I hypothesize that existing fast depletion of the deep St. Peter occurs due to lower-than-expected aquifer parameters of the aquifer. Further, current pumping of groundwater from the St. Peter, …

Beyond The Sentimental Cliche: How Local Communities Impact Residents And Shape Public Opinion, Kate Brunk

Theses and Dissertations

The Trump administration has recently established a rule that will prohibit abortion services providers from receiving Title X funds for the non-abortion family planning services they provide. Little public opinion research has focused on family planning and reproductive health topics outside of abortion. I find statistically significant experimental evidence that increasing perceptions of local need for a local reproductive health clinic caused subjects to be more supportive of federal reproductive health funding for local clinics. I did not find statistically significant correlational evidence that objective measures of poor reproductive health at the county level influence public opinion on federal reproductive …

Inked Bodies, Blank Pages; A Study Of Amazigh Tattooing, Hannah Mesouani

Theses and Dissertations

The tradition of Moroccan Amazigh tattooing reflects the values and lived experiences of the communities that partake in this sacred practice. Adorning their fellow women with symbols of protection, tribe alliances and fertility, Amazigh women display their core values on face and body that come to represent their community. The power of these images and the women that wear them have stood the test of time, even in a newly male-dominated, Islamic Morocco that frowns upon body modification and promotes a nationalism that leaves little room for Amazigh tradition. In a corner of the world where literacy rates are low, …

A Conceptual Mapping Approach For Presenting A Practical Past: Addressing Responsibility Through Contextualization In Information System Design For The Ward One Mobile Application, Sadia Obaid Khan

Theses and Dissertations

This paper presents and documents a model for telling history through technology using the Ward One application for iOS mobile devices as a test site for the idea of conceptual mapping. The historical-information delivery system was created to mobilize the rhetoricity of representation that is a procedural necessity of technological mediation.

The paper begins by explaining the exigence of the app—to tell the history of an African-American community displaced from the land now occupied by the University of South Carolina as a result of racially discriminating housing policies in Columbia, SC and across the United States. It then addresses the …

Sand, Water, Salt: Managing The Elements In Literature Of The American West, 1880-1925, Jada Ach

Theses and Dissertations

Sand, Water, Salt focuses on Progressive Era American literature that explores the theme of land management set in the so-called wasteland spaces of the arid deserts, semi- arid high plains, and Pacific Ocean. The rhetoric of turn-of-the-century land managers, engineers, and developers insisted that humans and their environments remained separate, thus affording humans the ability to control land from a safe distance. However, the works I examine in my project demonstrate that even thoroughly regulated environments remain lively and beyond total control. My project archive, which includes Progressive Era fiction, memoirs, irrigation maps, aerial photographs, dry farming manifestos, and other …

Prototyping A Social Media Flooding Photo Screening System Based On Deep Learning And Crowdsourcing, Huan Ning

Theses and Dissertations

This thesis aims to implement a prototype system to screen flooding photos from social media. These photos, associated with their geographic locations, can provide free, timely, and reliable visual information about flood events to the decision makers. This system is designed for the application to the real social media images, including several key functions: tweets downloading, image downloading, flooding photo detection, and human verification via a WebGIS application. In this study, a training dataset of 5,000 flooding photos was built based on an iterative method; a convolutional neural network (CNN) was then trained and applied to detect flooding photos. Also, …

A Choice To Engage: Selective Marginality And Dynamic Households On The 18th-19th Century Irish Coast, Meagan Conway

Theses and Dissertations

This research explores the nature of marginality on the peripheries of empire in 18th and 19th century rural Ireland. These shifting imperial borders, both cultural and geographic, are historically fluid spaces that have potential to impact individual decision-making, spark cultural change, and alter social dynamics under the pressures of foreign rule. This project focuses on individual rural households off the coast of western Ireland to understand the selective engagement (choices to accept or reject externally generated ideologies) of households in transnational systems, and the ways islanders generated a material reaction to prescribed narratives of marginality from the imperial epicenter. Expressions …

Bringing Culture Into The Classroom: The Impact Of Culturally Relevant Pedagogy On Student Engagement And Self-Efficacy In Social Studies, Siddeeqah K. Cruse

Theses and Dissertations

The presence of the achievement gap has plagued our education system for decades. One of the most astonishing trends has resulted in the racial achievement gap as White students drastically outperform minority groups with African American males being the most affected population. Educators have studied and implemented Culturally Relevant Pedagogy (CRP) to increase the achievement of African American males. CRP contends that all students are capable of learning and should be held to high expectations while using students’ culture and interests to drive instruction. This action research study examines the impact of culturally relevant teaching on the self-efficacy and engagement …

The Impact Of A Thematic Unit And Integration On Students’ Achievement In Social Studies, Holness Samuels

Theses and Dissertations

This action research study focused on a problem of practice observed in a Title 1 middle school in rural South Carolina, where seventh-grade students show low academic achievement levels in social studies, evidenced by low scores on teacher-made tests, district benchmarks, and the state standardized test. To address this problem of practice, research questions were formulated: What is the impact of implementing a thematic unit on World War One, an integrated approach, on students' motivation to learn social studies? What impact will the implementation of a thematic unit on World War One have on students’ perception of social studies? and, …

Divine Absence, Divine Presence: The Theological Arguments Of Elizabeth Singer Rowe’S The History Of Joseph, Laura Macgowan

Theses and Dissertations

Elizabeth Singer Rowe’s Biblical epic The History of Joseph (1736), which dramatizes the events of Genesis 37-45, stands out in her oeuvre not only generically—it is her only long narrative poem—but because of how rarely God appears as an intervening agent or subject of narrative attention. Rather than highlight God’s splendor by imbuing Scripture with poetic embellishment, as is her wont, Rowe’s language downplays God’s hand in a famously Providential story (Genesis 50.20). While God shows up most often as an entity to beseech or a cultural token to reference, pagan deities govern the plot’s action; Rowe relishes in …

Ammani Youth- Paradoxical Citizens On The Margins, Holly L. Smith

Theses and Dissertations

Cities are complex social environments representing a convergence of many physical and human processes which influence how young people form their identities and plan for their futures. The role of urban environments on social processes has received substantial attention. However, significantly less attention has been focused on how urban youth are impacted specifically as political actors. Youth are particularly exposed to feeling the impacts of historical and on-going geopolitical issues in and surrounding their urban environments. Amman, Jordan is a compelling location to examine urban impacts on young political actors because of the clear geopolitical changes taking place in and …

Amish Perspectives Of The Genetic Counseling Process, Brianna Teapole

Theses and Dissertations

The Amish are a population with a high concentration of genetic disorders who have informed our understanding of several genetic conditions. This culturally unique group has special need for genetic services. While clinics have been established to care for Amish individuals, such as the Community Health Clinic in Indiana, little research has been done on Amish perspectives of these services, specifically genetic counseling. Amish individuals who received genetic counseling from the Community Health Clinic were sent recruitment letters and a questionnaire via mail. The questionnaire consisted of demographic questions, a 7-item adapted Genetic Counseling Satisfaction Scale (GCSS), and open-response questions. …

Endolithic Microbial Carbon Cycling In East Antarctica, Natalie Tyler

Theses and Dissertations

Microbes adapt to inhospitable conditions by colonizing niches that protect them from severe environmental conditions, making them model organisms in the search for life on other planets. Endoliths are globally ubiquitous microbes that colonize structural cavities within rocks, which protect them from environmental stressors while maintaining access to nutrition and light sources. Despite harsh katabatic winds, extreme temperature fluctuations, harmful UV radiation and exposure to desiccation, endolithic communities have been observed in Antarctica. Previous studies have found viable and abundant microbial biomass through microscopy and the addition of isotopic labels. However, due to the slow metabolic activity of these microbes, …

The Warped One: Nationalist Adaptations Of The Cuchulain Myth, Martha J. Lee

Theses and Dissertations

In this dissertation, I trace the use of the mythic Irish hero Cuchulain by early Irish nationalists. From 1878 to 1939, Standish James O’Grady, Lady Augusta Gregory, and William Butler Yeats employed this figure for specific political and cultural agendas. Cuchulain makes a fitting symbol for the “poet warrior” stereotype that was purposely and incidentally cultivated during the cultural nationalist phase of the Irish Literary Revival, when writers were beginning to explore the Cuchulain myth to demonstrate cultural and linguistic ideals. Nationalists found in Cuchulain a symbol that could tie the cultural to the political and the political to the …

Convertirse En Inmortal, 成仙 Chéngxiān, Becoming Xian: Memory And Subjectivity In Cristina Rivera Garza’S Verde Shanghai, Katherine Paulette Elizabeth Crouch

Theses and Dissertations

Verde Shanghai, published in 2011 by Cristina Rivera Garza, is often used in discussions of Orientalism in Latina America and Mexico. The text employs tropes and stereotypes common in Orientalist thinking, but to label the work Orientalist and analyze it through that lens seems too simplistic. I argue that Verde Shanghai ultimately proves a refutation of Orientalism’s existence within Mexico, and, more broadly, an overall deconstruction of the East-West dichotomy. Rivera Garza appears more interested in using racial and cultural identities to dismantle the polar dichotomies in which her characters live, ultimately critiquing these frameworks in the outside world.

Nitrogen And Phosphorus Uptake In An Urban Stream Ecosystem, Nicolette A. Sheffield

Theses and Dissertations

Urban stream ecosystems are faced with high input levels of nitrogen (N) and phosphorus (P) from anthropogenic activities. N and P are important to plant growth and stream health; however, high levels can lead to algal blooms and eutrophication, a harmful effect to both aquatic life and water quality. Common urban sources of N and P include fertilizer, atmospheric deposition, stormwater outfall, and leaf-litter decomposition. Common urban stream features such as a flashier hydrograph, altered channel stability and morphology, increase in nutrient output (such as N and P), and heat retention, have been shown to result in an overall decrease …

Multi-Sensor Data Fusion Between Radio Tomographic Imaging And Noise Radar, Christopher Vergara

Theses and Dissertations

The lack of situational awareness within an operational environment is a problem that carries high risk and expensive consequences. Radio Tomographic Imaging (RTI) and noise radar are two proven technologies capable of through-wall imaging and foliage penetration. The intent of this thesis is to provide a proof of concept for the fusion of data from RTI and noise radar. The output of this thesis will consist of a performance comparison between the two technologies followed by the derivation of a fusion technique to produce a single image. Proposals have been made for the integration of multiple-input multiple-output (MIMO) radar with …

An Imputation Approach To Developing Alternative Futures Of Country Conflict, Zachary J. Kane

Theses and Dissertations

Understanding what causes countries to be in a state of violent conflict is of vital importance to developing realistic national strategies on both a regional and global scale. Given these causes, it is important to understand the effects of missing data, how to impute that data, and the interrelation between data elements. Utilizing both open source data and previously generated equations that predict a country’s likelihood to transition conflict statuses, this research projects data into the future and predicts each nations’ subsequent conflict statuses. Future data is populated using a novel approach inspired by stochastic regression imputation. The replicated future …

Simulating Maritime Chokepoint Disruption In The Global Food Supply, Ryan B. Walton

Theses and Dissertations

The three food crops of wheat, maize, and rice make up almost two-thirds of the world's dietary energy needs. Of these three, just six countries provide 70% of the global supply. Furthermore, soybeans account for three-quarters of global livestock feed, and only three countries provide 80% of the global supply. Considering over half of the world's exported supply of these four commodities are exported via maritime means, the free ow of marine traffic becomes paramount. Current models lack the ability to capture the inherent variance displayed in the maritime transport system, which can lead to inaccurate assumptions about how the …

Verification Of Autonomous Systems: Developmental Test And Evaluation Of An Autonomous Uas Swarming Algorithm Combining Simulation, Formulation And Live Flight, Corey A. Combs

Theses and Dissertations

This research was driven by the increase of autonomous systems in the current millennium and the challenging nature of testing and evaluating their performance. A review of the current literature revealed proposed methods for verifying autonomous systems, but few implementations. It exposed several gaps in the current verification and validation methods and suggested goals for filling them. Through the use of modeling, software in the loop (SITL), and flight test, this research verified an autonomous swarming algorithm for unmanned aerial systems (UAS) and validated an exemplar of a testing framework. Thirteen sets of three-vehicle swarm data produced over two days …

Operations Research Methods For Multi-Domain Campaign Phase Planning, John A. Schlicht

Theses and Dissertations

In "Antiaccess Warfare as Strategy," Tangredi posits the question and need to consider multiple domains and governmental and warfighting functions in various phases of campaign execution. Multi-domain integration within and across various phases of the joint campaign presents a host of non-linear factors that are compounded and amplified by uncertainties. Colonel Blotto is a simple game that is suited to compare traditional force-on-force military engagements where mass wins the day, but have had limited application to more complex military planning. This thesis explores the formulation schema, data-driven parameters, methods of calculation, and scenarios applicable to a generalized Colonel Blotto (General …

Nitrate Concentrations In Streams As A Function Of Crop Cover In Midwestern Agricultural Watersheds: Assessing The Role Of Corn And Soybeans, Jacob Tyler Piske

Theses and Dissertations

Increased availability and reduced cost of synthetic-nitrogen fertilizers have led to excess nitrogen being deposited in reservoirs. The accumulation of nitrogen (N) in reservoirs has negative effects, generating algal blooms, hypoxic zones, and poor drinking water quality. Corn and soybean utilize nitrogen at different rates, resulting in higher nitrogen fertilizer application to fields for corn than for soybean. This work examines whether the nitrate concentration in a stream may be correlated to the percentage of land devoted to growing corn or soybeans in the watershed. To investigate potential relationships, discharge (Q) and nitrate concentration data from ten USGS gauging stations …

Navigating Palimpsest’S Sea Garden: H.D.’S Spiritual Realism, Mari Anne Murdock

Theses and Dissertations

H.D.’s novel Palimpsest has often been analyzed using psychoanalytic theories due to her relationship with Sigmund Freud and his work. However, her own approach to the science of psychoanalysis reveals that she often complemented her scientific understanding with her syncretic religious beliefs, a perspective she referred to as “spiritual realism,” which suggests that analysis with a spiritual nuance may provide a deeper understanding of the novel’s intended purpose. Postsecular theory makes for a useful lens by which to analyze Palimpsest’s treatment of reintegrating spiritual knowledge into Freud’s secular understanding of the modern world by providing the benefits of such a …
