Determining Atmospheric Boundary Layer Behavior Over Mountainous Terrain Using Aircraft Vertical Profiles From 2009-2018 Nasa Student Airborne Research Program Data, Dallas McKinney 2020 Western Kentucky University

Determining Atmospheric Boundary Layer Behavior Over Mountainous Terrain Using Aircraft Vertical Profiles From 2009-2018 Nasa Student Airborne Research Program Data, Dallas Mckinney

Mahurin Honors College Capstone Experience/Thesis Projects

The atmospheric boundary layer (ABL) height separates turbulently mixed air and pollutants emitted at the ground from the free troposphere above and is an important parameter in numerical weather prediction and air pollution dispersion models. Discerning the ABL height over mountainous terrain has historically been difficult because of, for example, complex interactions with upper level winds, venting of humidity and aerosols into the free troposphere, and large spatiotemporal variability. ABL over mountainous terrain (MT) can closely follow the terrain, be flat, or be shallower than surrounding valleys depending on the time of day, synoptic conditions, and effects of the surrounding …

An Ethnic Cultural Landscape: German Breweries And Social Institutions In Covington, Kentucky, 1860-1920, Andrew Jones 2020 Western Kentucky University

An Ethnic Cultural Landscape: German Breweries And Social Institutions In Covington, Kentucky, 1860-1920, Andrew Jones

Mahurin Honors College Capstone Experience/Thesis Projects

A useful marker for recognizing the impact that ethnic groups make to the social and cultural characteristics of a city are the institutions and material landscapes created by those groups. In northern Kentucky, during the 19th and early 20th centuries, German immigrants and their descendants in the city of Covington established institutions such as breweries, saloons, social associations, and churches that became the heart of ethnic neighborhoods and shaped the form of the landscape. This research examines institutional and cultural landscape markers of German cultural identity in the city of Covington, Kentucky, from 1860 to 1920. Demographic and spatial data …


Transitioning From Emergency Remote Learning To Deep Online Learning Experiences In Geography Education, Richard B. Schultz, Michael N. DeMers 2020 Illinois Mathematics and Science Academy

Transitioning From Emergency Remote Learning To Deep Online Learning Experiences In Geography Education, Richard B. Schultz, Michael N. Demers

Publications & Research

Recent events resulting from the Covid-19 pandemic precipitated a triage-like environment wherein experienced faculty were forced to convert courses rapidly to online venues. This unexpected circumstance forced educators to adopt different learning theories of which they were largely unaware. The results were predominantly unsatisfactory for both learner and educator. This paper provides perspectives to this unfortunate circumstance, describes positive and negative aspects of the experiences, presents best practices for deep online learning, and challenges geography educators to learn how instructional design for online courses can be leveraged. The goal is to provide a forum for online learning in geography education.


Biophysical And Socioeconomic Impacts Of Farmer Managed Natural Regeneration In Burkina Faso, Basnewende Brice Fulgence Zoungrana 2020 South Dakota State University

Biophysical And Socioeconomic Impacts Of Farmer Managed Natural Regeneration In Burkina Faso, Basnewende Brice Fulgence Zoungrana

Electronic Theses and Dissertations

Human actions such as overgrazing, the development of cities at the expense of forests, high intensity and poor agricultural management, and so forth, reduce the resources available for future generations. Because Earth has limited resources, it is important to judiciously use and manage natural resources. Human actions towards nature are the focus of my research in Africa. Increased demands for grazing, agriculture, and ecosystem services led some farmers in developing countries to use unsustainable practices, which may lead to low incomes and poor food nutrition for households. Farmer managed natural regeneration (FMNR) may be a solution to these issues. FMNR …


Addressing The Skills Gap Of Geospatial Professionals In The Fourth Industrial Revolution, Shannon Marie Doyle 2020 Walden University

Addressing The Skills Gap Of Geospatial Professionals In The Fourth Industrial Revolution, Shannon Marie Doyle

Walden Dissertations and Doctoral Studies

Leaders of geospatial organizations are ill-prepared to manage rapid technological change critical to environmental and economic development due to an outdated list of technical competencies. However, there is a lack of consensus in the geospatial industry concerning the desired technical competencies of organizations and a gap in the literature regarding future trends when defining additional geospatial technical competencies. Therefore, the purpose of this qualitative modified Delphi study was to determine how a nationwide panel of experts in the geospatial industry viewed the desirability and practicability of forward-looking technical competencies of geospatial professionals. The research questions for this study were grounded …


Geospatial Analysis Of Flooding In The Cypress Creek Watershed Due To Urban Sprawl, Michael Roland Boucher 2020 Walden University

Geospatial Analysis Of Flooding In The Cypress Creek Watershed Due To Urban Sprawl, Michael Roland Boucher

Walden Dissertations and Doctoral Studies

Harris County, Texas, experiences flooding almost every year, and the situation is getting worse. Uncontrolled development is leading to an increase in flooding events. This study investigated how rapid urbanization and sprawl led to a higher frequency and intensity of flooding in the Cypress Creek watershed in northern Harris County. According to urban ecology, the basis of the theoretical framework, the human actions on the environment are not just bystanders, but direct contributors as inputs. In this case, the outputs are the intensity of the flooding events caused by Hurricane Ike, the Memorial Day flood of 2016, and Hurricane Harvey. …


'Amageddon': The Unholy Trinity Of Class Monopoly Rent In The Emerald City, Elijah Connor Hansen 2020 Eastern Washington University

'Amageddon': The Unholy Trinity Of Class Monopoly Rent In The Emerald City, Elijah Connor Hansen

EWU Masters Thesis Collection

Intense redevelopment has steamrolled across Seattle’s South Lake Union and Belltown neighborhoods, home to the headquarters of the world’s largest ecommerce corporation, Amazon. After the corporation established a presence in what is now referred to as ‘Amazonia’ in 2007, the surrounding urban landscape underwent a colossal metamorphic overhaul as high-tech and biotech industries, along with bourgeois luxury high rises, replaced old warehouses and empty parking lots. These new industries have attracted tens of thousands of people to the city, resulting in an oversaturated housing supply and an ensuing housing affordability crisis as rents have continued to skyrocket year after year. …

Cartographic Efficacy: Histories Of The Present, Participatory Futures, Amber J. Bosse 2020 University of Kentucky

Cartographic Efficacy: Histories Of The Present, Participatory Futures, Amber J. Bosse

Theses and Dissertations--Geography

Throughout history, maps have held a particularly potent ability to inform and persuade their users. Recognizing the power maps and their modes of productions possess, participatory mapping has been celebrated for its capacity to empower systemically disenfranchised communities by way of establishing inclusive pathways for influencing collection and representation of spatial information. What has remained largely periphery to considerations of participatory mapping, however, has been discussions of map design. Decades of scholarship in both traditional and critical veins of cartography, however, argue that it’s the careful execution of design choices that grant the map its power. Without attention to design, …


Reserved For The Whole Earth: Forms Of Evidence, Ought Anxiety, And The Futures Of Geographic Inquiry, Eric M. Robsky Huntley 2020 University of Kentucky

Reserved For The Whole Earth: Forms Of Evidence, Ought Anxiety, And The Futures Of Geographic Inquiry, Eric M. Robsky Huntley

Theses and Dissertations--Geography

This dissertation examines geographic forms of evidence in the practices of landscape architects and geographers. I analyze evidence not only as an epistemic phenomenon, but as an aesthetic one, as well. Convincing an audience that the world is (or should be) one way and not another requires that knowledges be stacked, extended, and stitched together in a manner admissable to an audience. In the first two chapters, I use the case of the landscape architect Ian McHarg to examine how his approach to integrating scientific knowledge---a aesthetic response to what I theorize as 'ought anxiety'---grew alongside the environmental bureaucracy in …


Assessing The Climate Water Balance Model’S Ability To Predict Soil Moisture Variability And Species Distribution Of A Forested Watershed In The Northern Cumberland Plateau, Katherine J. Love 2020 University of Kentucky

Assessing The Climate Water Balance Model’S Ability To Predict Soil Moisture Variability And Species Distribution Of A Forested Watershed In The Northern Cumberland Plateau, Katherine J. Love

Theses and Dissertations--Forestry and Natural Resources

Spatial patterns of moisture and tree species have been studied using environmental gradients, often represented by terrain attributes in GIS. With climate change, GIS terrain variables, which are static as long as the elevation remains unchanged, will not reflect alterations in temperature, water cycle, and atmospheric conditions. In this thesis, the commonly used terrain variables and climate water balance variables were evaluated and compared for their ability to explain soil moisture and tree species distributions in a forested watershed in the Northern Cumberland Plateau. The results suggest that GIS terrain variables generally perform better than climate water balance variables, however, …


A Karst Feature Predictability Model Within Barber County, Kansas, Gary M. Kelner 2020 Fort Hays State University

A Karst Feature Predictability Model Within Barber County, Kansas, Gary M. Kelner

Master's Theses or Doctor of Nursing Practice

This research consisted of two topics: 1) geographic predictive models of karst features and 2), a petrographic study examining the lithology of the study area. The study area is a privately owned ranch in the Gypsum Hills of Barber County, Kansas and is known to have karst features. Two predictive models for karst features were utilized. Previously identified features, Light Detection and Ranging (LiDAR), and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) imagery aided in the creation of these predictive models. These predictability models also used the ESRI ArcMap software platform. The data for these models consists of slope, …


Social Agglomeration Forces And The City, Peter A. Luff 2020 Yale University

Social Agglomeration Forces And The City, Peter A. Luff

Library Map Prize

The presence of “agglomeration forces” in production markets is widely accepted and has been recently quantified in the economics literature. Social scientists have done little theoretical work, however, and even less quantitative work, on how the logic of agglomeration might also apply to social groups and the gains that people derive from their social interactions. This paper attempts to bridge this gap by modeling and measuring the benefits in terms of social prestige that arose from the spatial concentration of socialites in Manhattan in the 1920s. I formulate a model of location-based social status determination that illustrates why these benefits …


Using Unmanned Aircraft Systems To Identify Invasive Species, Tithe Ahmed 2020 Western Kentucky University

Using Unmanned Aircraft Systems To Identify Invasive Species, Tithe Ahmed

Mahurin Honors College Capstone Experience/Thesis Projects

Invasive species serve as a threat to native biodiversity and ecosystem sustainability. Combatting the spread of invasive species requires long-term physical and monetary commitments. In Balule Nature Reserve of Greater Kruger National Park, South Africa, Opuntia ficus-inidica (the common prickly pear) has been a relentless invader, displacing the local flora and fauna. The goal of this project is to battle invasive species such as prickly pear using efficient and inexpensive technology: unmanned aerial vehicles (UAVs or drones) and multispectral sensors.

Using a 4-bandwidth Parrot Sequoia multispectral sensor in tandem with the DJI Phantom Pro 3TM UAV, images of land …


Investigating The Spatial And Statistical Dimensions Of Mortuary Choice In The Historical-Period Old City Cemetery In Roslyn, Washington, Sarah Rain Hibdon 2020 Central Washington University

Investigating The Spatial And Statistical Dimensions Of Mortuary Choice In The Historical-Period Old City Cemetery In Roslyn, Washington, Sarah Rain Hibdon

All Master's Theses

The historical-period Old City Cemetery in Roslyn, Washington contains individuals from diverse social backgrounds and exhibits considerable variation in mortuary expression. As such, the Old City Cemetery offers a unique opportunity to explore potential differences in social group mortuary practices spatially and statistically. Using burials in Roslyn’s Old City Cemetery, this project developed a methods framework to assess mortuary practice through demographics, burial location, and monument/plot attributes. I tested correlations between demographics and mortuary expression using spatial-statistical cluster analysis (Ripley’s K-Function), spatial density analysis (Kernel Density Estimation), and non-spatial statistical significance assessments (Factor analysis and Pearson’s R), and identified …


Comparing Rusle Ls Calculation Methods Across Varying Dem Resolutions, Amanda Moody 2020 Central Washington University

Comparing Rusle Ls Calculation Methods Across Varying Dem Resolutions, Amanda Moody

All Master's Theses

Soil erosion is a global problem that reduces land productivity and causes environmental degradation. Soil erosion models, such as the Revised Universal Soil Loss Equation (RUSLE), are used to estimate the severity and distribution of erosion. The topographic factor (LS), which combines slope length and angle, is an important part of RUSLE. This work compared two methods of L calculation, the grid cumulation (GC) and the contributing area (CA) methods, and two methods of S calculation, the neighborhood (NBR) and maximum downhill slope (MDS) methods. These were compared across digital elevation models (DEMs) of 1, 5, 10, and 30m resolutions. …


Innovative Approaches To 3d Gis Modeling For Volumetric And Geoprocessing Applications In Subsurface Infrastructures In A Virtual Immersive Environment, Pragya Srivastava 2020 West Virginia University

Innovative Approaches To 3d Gis Modeling For Volumetric And Geoprocessing Applications In Subsurface Infrastructures In A Virtual Immersive Environment, Pragya Srivastava

Graduate Theses, Dissertations, and Problem Reports (ETD)

As subsurface features remain largely ‘out of sight, out of mind’, this has led to challenges when dealing with underground space and infrastructures and especially so for those working in GIS. Since subsurface infrastructure plays a major role in supporting the needs of modern society, groups such as city planners and utility companies and decision makers are looking for an ‘holistic’ approach where the sustainable use of underground space is as important as above ground space. For such planning and management, it is crucial to examine subsurface data in a form that is amenable to 3D mapping and that can …


Using Unmanned Aerial Systems (Drones) With A Thermal Sensor To Map And Count Deer Population, Maxwell C. Ott 2020 The University of Akron

Using Unmanned Aerial Systems (Drones) With A Thermal Sensor To Map And Count Deer Population, Maxwell C. Ott

Williams Honors College, Honors Research Projects

The number of deer in an area is an important statistic for land managers to know, as overabundance has many negative effects. There are many methods that have been used to count deer in the past, such as using manned helicopters and airplanes, walking on foot, and conducting controlled hunts. UAS (unmanned aerial systems) is a growing field that provides many benefits over traditional methods of counting deer, such as lower cost and missions being less time consuming. Using a thermal sensor attached to a UAS makes it simple to spot any deer during a flight. Two main methods of …
