Linking Climate Change And Socio-Economic Impact For Long-Term Urban Growth In Three Mega-Cities, Qi Lu

Electronic Theses and Dissertations

Urbanization has become a global trend under the impact of population growth, socio-economic development, and globalization. However, the interactions between climate change and urban growth in the context of economic geography are unclear due to missing links in between the recent planning megacities. This study aims to conduct a multi-temporal change analysis of land use and land cover in New York City, City of London, and Beijing using a cellular automata-based Markov chain model collaborating with fuzzy set theory and multi-criteria evaluation to predict the city's future land use changes for 2030 and 2050 under the background of climate change. …

Russian Real Estate Purchases In Finland, 1990-2016, Mika Hasanen

Electronic Theses and Dissertations

Foreign real estate ownership has been a frequent topic in the Finnish public discourse in the 2010s. Real estate purchases by Russian citizens have received lots of negative attention. In this thesis, the spatial distribution of real estate bought by Russians was studied. Purchases between January 1990 and August 2016 were mapped and analyzed using Getis-Ord Gi* hot spot analysis. The home addresses of the buyers were also geocoded to find out where the majority of buyers live, and geodetic distances to their properties were calculated. Buildings on these properties were analyzed to examine motives for the purchases.

Growth Potential And Genetic Diversity Of Yellow Perch In South Dakota, Alex J. Rosburg

Electronic Theses and Dissertations

Yellow Perch Perca flavescens represent a valued sport fish throughout their range and are an important prey species for piscivorous fishes. In South Dakota, two distinct population types of Yellow Perch have been characterized that differ in growth, survival, and recruitment patterns. Fast growth populations exhibit high growth rates, high mortality, low population density, and inconsistent recruitment. In contrast, slow growth populations are characterized by reduced growth rates, low mortality, high population density, and relatively consistent recruitment. The role of genetics in contributing to these population characteristics is currently unknown. To address these questions, I used high-throughput restriction-site associated DNA …

The Effect Of Road Crossings On Stream-Associated Salamanders Within Holly Springs National Forest, Caleb Ashton Aldridge

Electronic Theses and Dissertations

Road crossings have significant effects on wildlife, but there is limited information on how road crossings affect stream-associated salamanders. Stream-associated salamanders are vital to their ecological communities and are likely to experience the effect of roads more readily than other species due to their physiological characteristics. To test the effects of road crossings on stream-associated salamanders, I surveyed 12 pairs of confluent streams – one stream crossed by a road and the other not in each pair – within Holly Springs National Forest, Mississippi. Surveys in the summer of 2015 were used to measure abundance and species richness of stream-associated …

A Phenomenographic Study Of Student Engagement Using Gis-Story Maps In An Eighth-Grade Social Studies Classroom, Esohe E. Egiebor

Electronic Theses and Dissertations

This qualitative phenomenographic study explores students' engagement using gis-story maps in an eighth-grade social studies classroom from a southeastern United States’ school district. The study answered the following questions: (1) how do eighth-grade students perceive their engagement with social studies when it is taught using story maps? (2) how do eighth-grade students perceive the relationship between gis, story maps to their own life? This study investigates students' engagement from the perspective of the students rather than the teacher. Qualitative data collection involved classroom observations, student-written reflections, and oral interviews of fourteen student-participants. The data analysis reveals that students perceive story …

Cold War New York: Postmodernism, Lyricism, And Queer Aesthetics In 1970s New York Poetry, Jared James O'Connor

Electronic Theses and Dissertations

This thesis explores the poetry of Joe Brainard and Anne Waldman, two poets of the critically neglected second-generation New York school. I argue that Brainard and Waldman help define the emerging discourse of postmodern poetry through their attention to cold war culture of the 1970s, countercultural ideologies, and poetic form. Both Brainard and Waldman enact a poetics of vulnerability in their work, situating themselves as wholly unique from their late-modernist predecessors. In doing so, they help engender a poetics concerned not only with the intellectual stakes but with the cultural environment they are forced to navigate. Chapter 1 explores Brainard's …

The Normative Approach Of The Catholic Tradition In The Ethical And Religious Directives For Resolving Ethical Dilemmas Regarding Medical Technology, David G. Garvis

Electronic Theses and Dissertations

The dissertation engages the Catholic Tradition enunciated in the Ethical and Religious Directives for Catholic Health Care Services to provide a normative approach for resolving ethical dilemmas regarding pivotal breakthroughs in medical technology.

This normative ethical approach has two components: a normative framework for Catholic health care ethics that adopts practical ethical principles as enunciated in the Ethical and Religious Directives (Chapter 2) and secular decision-making models in organizational and clinical ethics that are consistent with the Catholic Tradition (Chapter 3).

At the end of the theoretical analysis in these chapters, the conclusion to Chapter 3 explains how this normative …

Monitoring Pollen Counts And Pollen Allergy Index Using Satellite Observations In East Coast Of The United States, Murat Cagatay Kececi

Electronic Theses and Dissertations

Allergic diseases have become increasingly common over the world during the last four decades, and they are affecting millions of people. Pollination is an important process in the life cycle of plants. However, pollen exposure is associated with allergic diseases such as asthma and seasonal allergic rhinitis (hay fever). As a result, the total annual expenditure for asthma-associated morbidity is about $56 billion in the United States, and the overall cost of allergic diseases is over $18 billion annually. For allergic rhinitis, the annual medical cost is approximately $3.4 billion. The intensity and frequency of the pollen exposures can be …

Rail Rebound: The Impact Of Freight Rails On Regional Development In The United States, 1970-2010, Bishal Bhakta Kasu

Electronic Theses and Dissertations

Railroads have played a critical role in economic growth and development, and they exert a tremendous impact on the distribution and redistribution of the population. However, the impacts of railroads, especially freight rails, on population change and socioeconomic development are not well understood. This study fills the gap in the literature by examining the demographic and socioeconomic impacts of freight rails using county-level data in the continental United States from 1970 to 2010. The demographic and socioeconomic changes are measured by eleven dependent variables. Of those eleven, six are demographic (population, young, old, White, Black, Hispanic) and five are socioeconomic …

A Comparison Of Land Use And Land Cover In Public Lands Of The Northwestern Great Plains And High Plains Ecoregions And The Implications For Grassland Birds, Dawn L. Siemonsma

Electronic Theses and Dissertations

Loss and degradation of grassland habitat are driving forces that contribute to widespread declines of grassland birds in the United States. Many studies have evaluated habitat needs for the conservation of grassland birds, but the relative contribution of public lands in representing and maintaining avian biodiversity remains poorly understood. Having a better understanding of the role that publicly managed grasslands play in the conservation of grassland bird habitat is important for assessing the value of the investment the American public makes in these lands. Therefore, I investigated spatial relations among variations in amounts and distributions of publicly owned and managed …

Intrinsic Factors Affecting Decomposition Changes In Archaeological Head Hair From Kellis 2 Cemetery, Dakhleh Oasis, Egypt, Kathleen Cole

Electronic Theses and Dissertations

Post-mortem hair root degradation, and associated characteristics such as post-mortem root banding, brush-like ends, and hard keratin points, has remained a little understood phenomenon in the forensics discipline since its discovery in the 1800's. At present, the underlying causes of these characteristics are still unknown. In addition, there is no standardization for preparing samples for forensic or archaeological analysis. In this study, 1200 hairs from a total of 51 individuals (males, n = 22; females, n = 29) ranging in age from 16 to 60+ and interred at the Kellis 2 cemetery in the Dakhleh Oasis, Egypt are examined microscopically …

For The Good That We Can Do: African Presses, Christian Rhetoric, And White Minority Rule In South Africa, 1899-1924, Ian Marsh

Electronic Theses and Dissertations

This research examines Christian rhetoric as a source of resistance to white minority rule in South Africa within African newspapers in the first two decades of the twentieth-century. Many of the African editors and writers for these papers were educated by evangelical protestant missionaries that arrived in South Africa during the nineteenth century. Most prior research on these presses has examined the importance of Christianity, but has not taken into account the evolution of its use over the entirety of the period. Without this emphasis on evolving utilization, the current scholarship lacks a complete understanding of African newspapers and their …

Hippieland: Bohemian Space And Countercultural Place In San Francisco's Haight-Ashbury Neighborhood, Kevin Mercer

Electronic Theses and Dissertations

This thesis examines the birth of the late 1960s counterculture in San Francisco's Haight-Ashbury neighborhood. Surveying the area through a lens of geographic place and space, this research will look at the historical factors that led to the rise of a counterculture here. To contextualize this development, it is necessary to examine the development of a cosmopolitan neighborhood after World War II that was multicultural and bohemian into something culturally unique. It was within this space that a wellspring of drop-out culture evolved from a combination of psychedelic drugs, experimental lifestyles, and anarchistic thought. The contention of countercultural place was …

Understanding Arson Through Community Resilience, Rhena South

Electronic Theses and Dissertations

Over 40,000 arsons were reported in the 2014 Uniform Crime Report; however, this number is underestimated since there are no official arson trends reported by the FBI due to the lack of agencies reporting this offense. Arson is one of the most destructive and under researched crimes. This lack of research can be attributed to the dual definition of arson – that is, the destruction of one's own property or someone else's property – the opportunistic nature of arson, and the inability to determine a measurable rate. The current study uses data from the Chicago Police Department's Citizen Law Enforcement …

The Global Adult Tobacco Survey (GATS) was modified for the purposes of this study and used to determine demographic factors and tobacco usage status. The modified GATS survey also included the LOC questionnaire which yielded the data. Seventy-four responses were recorded. The mean locus of control scores were …

Challenging Conventional Wisdom : Section 8 Housing And The Real Impact On Neighborhood Values In Louisville, Kentucky., Paul Francis Dries

Electronic Theses and Dissertations

Section 8 Housing was designed to de-concentrate poverty and spread affordable housing across communities. There are many studies that have evaluated the successes associated with the policy of dispersing the urban poor to the surrounding suburban areas in various cities. The positive impacts of dispersing the urban poor, in terms of education, self-esteem, and jobs, is well documented. There are fewer studies related to the potential externalities associated with these programs. This study uses advanced multiple regression techniques to study 170 Louisville neighborhoods to look at whether large concentrations of Section 8 housing have a negative impact on neighborhood housing …

This …

Speleogenesis And Delineation Of Megaporosity And Karst Geohazards Through Geologic Cave Mapping And Lidar Analyses Associated With Infrastructure In Culberson County, Texas, Jon T. Ehrhart

Electronic Theses and Dissertations

The Gypsum Plain region of the Delaware Basin hosts approximately 1800 km² of the Castile Formation outcrop. A myriad of karstic developments from closed sinkholes to large multi-kilometer cave systems have been documented within the region. Karst studies on the distribution and speleogenetic evolution within Castile strata began within the last decade with ever increasing data resolution. In this study, a combination of both physical field surveys and analyses of high resolution (~30 cm accuracy) LiDAR data was used to create a theoretical model for karst development across the region. This idealized model considers speleogenetic formation type variations (hypogene …

How The City Of Indianapolis Came To Have African American Policemen And Firemen 80 Years Before The Modern Civil Rights Movement., Leon E. Bates

Electronic Theses and Dissertations

This study explores a series of events that occurred in the spring of 1876. The relationship between the Indianapolis city government, the Marion County Courts, the Indianapolis Police Department, and the African American community came together to usher in changes never before envisioned. The Indianapolis Police Department (IPD) was formed in 1855, then disbanded 12 months later in a political dispute. From 1857-to-1876, the IPD was all white. These changes took place as the Reconstruction era was coming to a close. The first Ku Klux Klan was at its apex, terrorizing black communities, and Jim Crow was coming into its …

Cardiovascular And Hematopoietic Responses To Volatile Benzene Exposure., Wesley Tyler Abplanalp

Electronic Theses and Dissertations

The rapid and recent increase in the global epidemic of diabetes and cardiovascular disease suggests a strong component of the environment is contributing. Benzene is a ubiquitous volatile pollutant generated by cigarette smoke, automobile exhaust, wildfires and industrial activities. Consequently, it is found in almost all urban and rural air samples. Benzene is known to cause hematotoxicity and its metabolism generates oxidative stress. Although, benzene has been studied for many years, few investigations have probed what influence benzene exposure may have on other physiological processes. Here we hypothesize that benzene metabolism by hepatic-CYP450 2E1 generates oxidative stress and inflammation, which …

Structure, Spending, And Democracy : A Study Of Municipal Governments., Neal Mcintyre Turpin

Electronic Theses and Dissertations

The debate over the effect of government structure is one of the most examined aspects of administration. At the municipal level, much of this work has focused on the structural reforms of the Progressive era. Three of these reforms –city managers, at-large elections, and non-partisan elections –were meant to make cities more professional and efficient. Three more –initiatives, referenda, and recalls –were meant to make cities more democratic. A large segment of this literature has studied what effects these structures have on local government spending, and results have been mixed. This dissertation seeks to examine what effects structural reform elements …

Putting Christians On The Map : Topographic Mosaics From Late Antique Jordan As Representations Of Authority And Status., Tracey Elizabeth Eckersley

Electronic Theses and Dissertations

In this dissertation, I examine nine ecclesiastic floor mosaics from Late Antique Palaestina and Arabia that contain topographic motifs ­­˗ images of cities set in realistic or stylized landscapes. Previous interpretations of the pavements have been limited by two assumptions: that artists or bishops were solely responsible for determining the compositions, and that only religious interpretations were intended for church pavements. Inscriptions indicating that patrons were generally lay people and iconography that encourages secular interpretations complicates both assumptions. This study investigates the mosaics in light of Late Antique euergetism in order to determine why donors included architectonic elements in the …

Effect Of Migration, Carrying Capacity, And Fecundity On The Formation Of Clinal Patterns During Range Expansions., Neha J. Angal

Electronic Theses and Dissertations

Range expansions, empirically and in simulations, lead to clinal patterns of genetic diversity. Clines are often used as spatial markers of past migrations. This study investigated the effects of migration, growth, and carrying capacities on clinal patterns during range expansions, using forward-time simulations in Nemo. Initial results show, in the absence of prior population structure, range expansions result in a loss of diversity strongly affected by migration, growth, and carrying capacity. This loss of diversity did not persist to the final generation, corresponding to 10,000 years, indicating clinal patterns are less durable than previously assumed—challenging the utility of clinal patterns …

Tornado Density And Return Periods In The Southeastern United States: Communicating Risk And Vulnerability At The Regional And State Levels, Michelle Bradburn

Electronic Theses and Dissertations

Tornado intensity and impacts vary drastically across space, thus spatial and statistical analyses were used to identify patterns of tornado severity in the Southeastern United States and to assess the vulnerability and estimated recurrence of tornadic activity. Records from the Storm Prediction Center's tornado database (1950-2014) were used to estimate kernel density to identify areas of high and low tornado frequency at both the regional- and state-scales. Return periods (2-year, 5-year, 10-year, 25-year, 50-year, and 100-year) were calculated at both scales as well using a composite score that included EF-scale magnitude, injury counts, and fatality counts. Results showed that the …

Imagining The Nigerian Nation Through The West African Pilot 1960-1966., David Zintak

Electronic Theses and Dissertations

The independence era in Nigeria, ushered in after 1960 and ending in 1966 with the fall of the civilian-elected government in a military coup, was a pivotal juncture in the construction and imagining of the nation and the citizen. Ideas of what a citizen should act like, dress like, and what mindsets were proper to hold were discussed frequently in the media. One critically important media outlet during the independence era was the West African Pilot. The Pilot is generally considered an influential nationalist publication during and prior to this era. This thesis explores how Nigeria was imagined through the …

Electronic Theses and Dissertations

The purpose of this quantitative study was to examine whether differences in student course outcomes as defined by final course grades existed between three content delivery methods in career and technical education courses: Traditional (face to face), hybrid, and online. Final course grades in career and technical education courses at one community college for the Fall 2011 through the Fall 2015 semesters were used in this study to compare the success of students in courses employing the three content delivery methods. The outcomes for male and female students and the outcomes for traditional and nontraditional students in career and technical …

Aaaneurysm Outreach Screening Data And Emergency Healthcare Accessibility In Louisiana: Identifying High-Risk Populations For Targeted Interventions, Amy M. Poole

Electronic Theses and Dissertations

Abdominal aortic aneurysms are the third leading cause of sudden death in men 60 years and over. AAAneurysm Outreach provides free screenings to residents of Louisiana and beyond. Service areas were calculated for each AAAneurysm Outreach screening event location and stroke center. Data provided by the 2010 U.S. Census, the American Community Survey, and the Behavioral Risk Factor Surveillance System were used to describe demographics of the underserved populations and to identify high-risk areas for targeted interventions. Twenty-five percent of age-eligible Louisianans reside outside optimal drive-time-to-screening-event zones but within spatially clustered areas of increased prevalence rates. The maximum drive-time-to-treatment zones …

Spatio-Temporal Analysis Of Point Patterns, Abdul-Nasah Soale

Electronic Theses and Dissertations

In this thesis, the basic tools of spatial statistics and time series analysis are applied to the case study of the earthquakes in a certain geographical region and time frame. Then some of the existing methods for joint analysis of time and space are described and applied. Finally, additional research questions about the spatial-temporal distribution of the earthquakes are posed and explored using statistical plots and models. The focus in the last section is in the relationship between number of events per year and maximum magnitude and its effect on how clustered the spatial distribution is and the relationship between …

Constructing Urban Life : A Study Of Automobile Dependency In 148 Mid-Size U.S. Cities., Chad Paul Frederick

Electronic Theses and Dissertations

Automobile-dependent sprawl remains the dominant urban development paradigm in the United States. One reason for this is that the automobile is assumed to be more beneficial to the local economy than it is detrimental to society. Both sides of this assumption are wrong. First, local economies do not benefit much from automobile dependency. On the contrary, multimodal cities have lower unemployment, higher wages for African-Americans, and more efficient property markets. In addition, while it is true that multimodality means slightly higher taxes, the total value of living in multimodal cities far surpasses automobile-dependent cities with a massively improved quality of …

An Evaluation Of Multiple Endmember Spectral Mixture Analysis Applied To Landsat 8 Oli Images For Mapping Land Cover In Southern Africa's Savanna., Fernando Ferreira Caixeta

Electronic Theses and Dissertations

Mapping land cover in southern Africa’s savannas using traditional pixel based remote sensing techniques can be very challenging due to the heterogeneity of its vegetation structure and the spectral difficulty in separating similar land covers across various land uses. In order to overcome these complications, a Multiple Endmember Spectral Mixture Analysis (MESMA) provides a potential remote sensing approach to quantify spectral variation in the physical environment at a subpixel level. The MESMA approach was applied in the study area of the Mayuni Conservancy, in Namibia. Results show that 32.3% of the study area is covered by photosynthetic vegetation (PV), 32.0% …
