Environmental Injustice And Racial/Ethnic Heterogeneity In Houston, Texas, Michel G. Loustaunau Garcia

Open Access Theses & Dissertations

This Thesis seeks to contribute to distributive environmental justice (EJ) research by analyzing racial/ethnic and intra-ethnic disparities in potential health risks from exposure to hazardous air pollutants (HAPs) in Harris County, the most populous county in Texas. Previous EJ research in this urban area has not examined intra-ethnic heterogeneity in exposure to air pollutants or attempted to compare social disparities in exposure to air pollution caused by vehicular (mobile) and point (stationary) sources. The goal of this study is to determine how the EJ implications of cancer risks from inhalation exposure to HAPs from mobile and stationary sources differ across …

Implementing Large Eddy Simulation To Numerical Simulation Of Optical Wave Propagation, Diego Alberto Lozano Jimenez

Open Access Theses & Dissertations

In this study, we want to simulate long-range laser propagation in atmospheric turbulence. The numerical simulations are carried out to study the impact of strong atmospheric turbulence in spatial, temporal, and related spectral domains. The first section of this study will be concerned with modeling this numerical simulation in Kolmogorov and non-Kolmogorov spectrum. To validate our numerical simulation, we will compare the statistical parameter to theoretical approximation in both Kolmogorov and non-Kolmogorov spectrums. Once the code is validated, we want to integrate Large Eddy Simulation (LES) turbulence modeling. LES simulations allowa us to study strong fluid turbulence and can predict …

Design Of Robotic Tram Unit For Field Data Collection, Quetzalcoatl Mendoza Rosas

Open Access Theses & Dissertations

Satellite remote sensing is the most applied method for detection and measurement of electromagnetic energy and its interaction with Earth surface. the analysis of the data acquired can provide important information with uses in areas as like weather forecasting, military intelligence and environmental and resources location. Due to the great distance from where the samples are taken and even with the most sophisticated sensor it is impossible to have an exactly replica of the Earth surface. As a result, scientist analyze imagery where a single pixel can be the representation of a 30 by 30 meters area of land. This …

Geometry, Timing, And Kinematics Of Neogene Extensional And Transtensional Structures Of Southern Death Valley: Implications For Regional Reconstructions And A Corrective Method For Rigid Body Rotations, Zachariah Fleming

Open Access Theses & Dissertations

Chapter 1:Advancements in computing capabilities over the last decade have allowed for the routine creation of Structure from Motion-Multiview Stereo (SfM-MVS) terrain models that can serve as base for high resolution geologic mapping. Outcrops models developed from these systems are high-resolution, photo-realistic 3D base providing unprecedented capability for geometric analysis. Yet, before this technology becomes a mainstay of field geology, the potential errors associated with it must be well understood. Here, we compare orientation measurements from multi-point analyses on the SfM-MVS point clouds to those taken in the field with the objective of resolving the geometry of complex folds within …

Our Regionalism, Jessica Bulman-Pozen

Faculty Scholarship

This article provides an account of Our Regionalism to supplement the many accounts of Our Federalism. After describing the legal forms regions assume in the United States — through interstate cooperation, organization of federal administrative agencies, and hybrid state-federal efforts — it explores how regions have shaped American governance across the twentieth and early twenty-first centuries.

In the years leading up to the New Deal, commentators invoked regions to resist centralization, arguing that state coordination could forestall expansion of the federal government. But regions were soon deployed to a different end, as the federal government relied on regional administration to …

We compare our proposed deep neural network method to a linear regression model and a traditional artificial neural network on 62 operating areas, each of which has at least 10 years of data. The proposed deep network outperforms traditional artificial neural networks by 9.83% weighted …

Complementary And Alternative Medicine Careers Following A Science Academy For Underrepresented Minority Students, Tolulope Oyelowo

Walden Dissertations and Doctoral Studies

Minority groups experience disproportionately worse health outcomes. An identified solution is to increase the number of minorities providing healthcare in their own communities. Primary care complementary and alternative medicine (CAM) providers are a potential resource. Many investigators have demonstrated the efficacy of science-based pipeline programs for increasing the roles of students in allopathic health professions. Whether these programs influence matriculation of minorities into a CAM university is unknown. The main purpose of this study was to gain an understanding of a pre-college science academy at a CAM university and determine whether the experience increased interest in and motivation for CAM …

College Rotc Cadets' Perceptions Of Gender Fairness With Selective Service Registration, Barrett Peavie

Walden Dissertations and Doctoral Studies

The U.S. Selective Service System currently excludes women from the talent pool based upon the DoD's 1981 ban on women in direct combat. The DoD has removed the exclusion and has implemented a gender-neutral policy standard for assignments. However, there appears to be a misalignment of national security policy as it relates to gender fairness that impacts Reserve Officer Training Corps (ROTC) participants in particular. Using Durkheim's functionalism theory as the theoretical foundation, the purpose of this phenomenological study was to examine institutional differences in policies regarding justice and gender among ROTC participants who are between 18 and 26 years …

Successful Strategies For Implementing An Enterprise Resource Planning System, Arrogah Adade-Boafo

Walden Dissertations and Doctoral Studies

The enterprise resource planning (ERP) implementation success rate is as low as 30%.

Forensic Detection For Earnings Management In Selected Code Law Nations Of Europe, Jef Lee Garner

Walden Dissertations and Doctoral Studies

This study investigated earnings management in European firms. The private investors became victims of manipulated earnings where few laws offered regulatory oversight. The study forensically examined the attributes of earnings management identified using a discretionary accrual model published in Jones' work and Schippers' work. The firms' managers should fulfil agency theory when they made reporting decisions, and they should act in the investors' best interests to fulfil stewardship theory. The managers failed as they seemed to favor insiders when they reported manipulated earnings to outsiders like small investors even though the managers published financial reports conforming to the International Financial …

Finding Influential Nodes For Integration In Brain Networks Using Optimal Percolation Theory, Gino Del Ferraro, Andrea Moreno, Byungjoon Min, Flaviano Morone, Úrsula Pérez-Ramírez, Laura Pérez-Cervera, Lucas C. Parra, Andrei Holodny, Santiago Canals, Hernán A. Makse

Publications and Research

Global integration of information in the brain results from complex interactions of segregated brain networks. Identifying the most influential neuronal populations that efficiently bind these networks is a fundamental problem of systems neuroscience. Here, we apply optimal percolation theory and pharmacogenetic interventions in vivo to predict and subsequently target nodes that are essential for global integration of a memory network in rodents. The theory predicts that integration in the memory network is mediated by a set of low-degree nodes located in the nucleus accumbens. This result is confirmed with pharmacogenetic inactivation of the nucleus accumbens, which eliminates the formation of …

The Impact Of Inquiry-Based Learning On Academic Achievement In Eighth-Grade Social Studies, Lindsey A. Bailey

Theses and Dissertations

The problem of practice described in this paper was identified by varying academic performances of students in a middle school located in South Carolina. The identified problem led the researcher to formulate a research question: What is the impact of inquiry-based learning on academic achievement for eighth-grade students in social studies? The purpose of this study is to determine if implementing inquiry-based learning will affect the academic achievement of students in social studies. Action research allows teachers to study their own classrooms to better understand them and to be able to improve their quality or effectiveness (Mertler, 2014). Action research …

South Carolina Preschool Teachers’ Perceptions And Experiences Implementing Critical Literacy In The Preschool Classroom, Rebecca Weissman

Theses and Dissertations

Critical literacy situated within a critical theoretical and pedagogical paradigm focuses specifically on exploring the sociopolitical implications of texts and challenging information rather than taking it at face value. The present study constitutes a case study that describes the perceptions and experiences of seven preschool teachers who employ critical literacy in their early childhood classroom and how their pedagogy fits within the existing themes seen in the early childhood literature. Specifically, this case study is an instrumental collective study, consisting of in-depth interviews. Through qualitative analysis of these interviews a variety of specific pedagogical methods for implementing critical literacy are …

Making Cents Of It: How The Focus On Financial Aid By Selective Universities May Not Be Enough To Attract More Low-Income, High-Achieving Students, Troy A. Mothkovich

Theses and Dissertations

Most low-income, high-achieving students in the United States neither attend nor apply to selective universities despite research that shows that they are just as likely as their high-income peers to succeed if they do apply to those schools. Despite the fact that many universities have begun offering substantial financial aid packages that would often make it cheaper to attend a selective private university than a state school, low-income, high-achievers tend not to apply to selective universities. Researchers have carried out many quantitative studies testing possible variables that could influence these students’ college application decisions. However, there has been a lack …

The Impact Of Project-Based Learning On Student Learning Perspectives And Achievement In A Social Studies Classroom, Jason Brisini

Theses and Dissertations

The purpose of this study was to ascertain the possible impact of project-based learning on student learning perspective and achievement in a social studies classroom. American schools are in an era of standardized testing based on standards-driven curricula that only teaches basic recall and recognition. School curriculum should be focused on providing students with the skills necessary for them to be successful after high school graduation. Higher-level thinking skills such as critical thinking, collaboration, and self-direction are not easily learned with traditional, essentialist teaching methods. Students can quickly look up facts with ready access to the internet, so they need …

The Popular Education Question In Antebellum South Carolina, 1800-1860, Brian A. Robinson

Theses and Dissertations

This dissertation reviews the struggle for popular education in Antebellum South Carolina. It contends that the failure of popular education in South Carolina was not a foregone conclusion nor was it mistake by school administration or state leaders, but instead, the failure to provide education for the white majority was the result of an intended goal. This project concludes that South Carolina remained without a system of public schools for the majority of citizens because those who opposed general education firmly believed popular education held the seeds of revolution while ignorance the better tool to perpetuate the status quo.

The Effects Of A Gamified Curriculum On High-School Students, Joshua Kyle Bastean

Theses and Dissertations

One of the emerging trends in education is gamification, a concept that has been applied in other fields, such as business and advertising, with great success. Gamification can be defined as adding game elements to non-game constructs. This study followed a high-school Algebra II teacher and 10 of her students in an attempt to document the effects of gamification on student academic engagement. Multiple methods of data collection were used to gather data from students and teachers. After analysis, the data showed that gamification had a positive effect on student academic engagement. The results were used to create an action …

Tweets About Tornado Warnings: A Spatiotemporal And Content Analysis, Raelene C. Campbell

Theses and Dissertations

Throughout the United States, tornadoes frequently occur throughout the entire year. With each tornado there is a tornado warning that the National Weather Service (NWS) issues with a goal of protecting life and property. By using social media, these messages quickly reach the public. By analyzing Twitter data, this study aims to gain a spatiotemporal understanding of tweets, including when and where they most frequently occur. Most tweets occur within the warning time (temporal) and inside the warning polygon (spatial). To gain a better understanding of the information the tweet contains, a content analysis shows key warning characteristics such as …

East Branch Of The Cooper River, 1780-1820: Panopticism And Mobility, Lisa Briggitte Randle

Theses and Dissertations

In recent years historical archaeologists have employed the panoptic plantation approach to examine issues of surveillance and control at plantations. Despite new scholarship in the area of the panoptic plantation, few studies place the enslaved laborer at the center and the planter-elite on the periphery. Failure to broaden the scope of studies that focus on enslaved laborers minimizes the importance of the differences in perception, cognition, and landscape between the planter-elite and the enslaved laborers. The aim of this study is to determine potential enslaved laborer mobility and how cognitive predictive models can aid in identifying potential locations for archaeological …

From Rhetoric To Response: Climate Change, Conflict, And Development In Karamoja, Uganda, Daniel Abrahams

Theses and Dissertations

This dissertation addresses the broad question: How do the discourses of climate change and conflict travel across time and space to become policy, programming, and ultimately a development initiative that exist on the ground? To answer this question, I broke the research into three separate papers. The first examines how the US policy community approaches, understands and seeks to address the discourses of climatesecurity. The second examines the ways in which climate change affects conflict outcomes in Karamoja, Uganda. And the third, using the efforts of Mercy Corps in Karamoja as a case study, examines the realities and opportunities in …

Historical Inquiry And Student Perceptions Of Cultural Groups In A Social Studies Classroom, Michelle Pope

Theses and Dissertations

This dissertation addresses a problem of practice stemming from the accountability movement and its emphasis on high-stakes testing in the social studies classroom. An examination of the problem of practice led to the research question: How does the use of the scientifically based method of historical inquiry affect student perceptions of cultures other than their own? The purpose of this action research study was to examine the use of historical inquiry as a means of combating the lack of depth in a formal curriculum focused on high-stakes testing and a hidden curriculum that promotes a “top-down,” Eurocentric approach to history …

Translating Slavery As Told To My Daughter, Victoria L.A. Carvelli

Theses and Dissertations

I am translating an excerpt of the work L’esclavage raconté à ma fille, by the French Guianese politician Christiane Taubira. A former Minister of Justice of France, Taubira is famous for her legislative work in recognizing slavery as a crime against humanity and instituting national educational efforts on the subject. The book is an exposition of the history of slavery, set in a storytelling, question-and-answer style, which has the merit of bringing a conversational and accessible aspect to a difficult topic.

I chose this work at the recommendation of one of my professors, and when I was unable to find …

Anthropogenic Influences On Sedimentation In The Chicken Creek Watershed Of South Carolina, Tyler L. Dearman

Theses and Dissertations

Anthropogeomorphic changes in response to destructive agricultural practices followed the arrival of European settlers into the Americas. The southeastern Piedmont physiographic region of the USA was severely affected by erosion and sedimentation following settlement in the 1700s and farming up through the 1930s. Deep floodplain aggradation formed uninterrupted alluvial deposits that extended many km. This research examines anthropogenic impacts of land-use change on valley bottom sedimentation in the Chicken Creek Watershed of South Carolina. Abrupt contacts between pre-settlement floodplain soils and a thick overburden of legacy sediment are common throughout the two-km study reach and provide clear evidence of extensive …

This study will also inform teacher educators …

Beyond Body Mixing: Race, Space, And The Meaning Of School Integration In A Chicago Suburb, Megan Rigsby Klein

Dissertations

Integration is often characterized as an effective means of fixing the problems associated with segregation. Whether with respect to residential segregation, education, or to public spaces in general, integration is seen as a way to undo the perils of racial segregation. Yet often times, integration takes a certain reified form with a large white majority and non-white minority. How do lived experiences of Black residents in integrated spaces affect their perceptions of integration? Drawing on data collected from arcHIVal research, participant observation, and in-depth interviews with long-term African American residents, this dissertation examines the ways in which race, space, and …

Ecospatial Orientation And American Literature, Lowell Wyse

Dissertations

Place is complex, and it undergirds and influences our fictional and nonfictional narratives in ways we often fail to recognize. In this dissertation, Lowell Wyse argues for a more holistic understanding of place's role in literature while asking what it means to read environmentally€”spatially, ecologically, and historically. Drawing from ecocriticism, which emphasizes the biological world, and geocriticism, which privileges the spatial, Wyse proposes a hybrid "ecospatial" criticism, with a particular emphasis on the role of maps in reading for place. With individual chapters on the nonfiction of William Least Heat-Moon, John Steinbeck's Salinas Valley fiction, Richard Wright's Native Son, and …
