Evaluation Of Measurement Data Across Eight Gis Basemaps Using Drumlins: Combining Basemaps Is Optimal, Gretchen A. Wambach, Alexander K. Stewart

The Compass: Earth Science Journal of Sigma Gamma Epsilon

Choosing the best basemap for landform data collection and analysis is fundamental for accurate measurements and usability. Different types of basemaps may affect how we perceive relief through a map (Phillips et al., 1975); thereby, affecting the precision of data collected. This project collected length and azimuth data of 60 drumlins in Western, NY from four different, ArcGIS online (AGOL)-provided basemaps, as well as two parallel-to-strike and two perpendicular-to-strike hillshades (n=4). Testing the mean length (1,662m, ±529) and azimuth (171°, ±0.3) data for uniformity across basemaps determined if any basemap is more or less reliable for ...

Why, New York City? Gauging The Quality Of Life Through The Thoughts Of Tweeters, Sheryl Williams 2022 The Graduate Center, City University of New York

Why, New York City? Gauging The Quality Of Life Through The Thoughts Of Tweeters, Sheryl Williams

Dissertations, Theses, and Capstone Projects

As a resource for social data, Twitter’s platform has been used to measure the quality of life through sentiment analysis. This capstone project explores another methodological technique—querying Twitter data around specific keyword terms to determine dominant topics, word patterns, and sentiment leanings in a geographical area. Focusing on New York City and Los Angeles for comparative analysis, the keyword term “why” will be used to build a Python analysis around topic modeling and sentiment analysis. Using this approach, the analysis reveals social and cultural differences, the overall sentiment of tweets, and subjects of interest to tweeters.

Our Streets: Increasing Equity In Active Transportation Planning Through Community Outreach, Jordan Hoy 2022 The University of San Francisco

Our Streets: Increasing Equity In Active Transportation Planning Through Community Outreach, Jordan Hoy

Master's Projects and Capstones

ABSTRACT Significant research has demonstrated that active transportation infrastructure is essential for the growth and livability of San Francisco: it increases access to economic opportunities, promotes overall improved public health, encourages mobility without contributing to roadway congestion, prevents traffic injuries and fatalities, and supports the sustainability goals of the city. Despite the fact that communities of color will benefit the most from active transportation infrastructure development, historical disenfranchisement in tandem with a lack of diverse representation within public participation contributes to an inequitable distribution of walking and biking investments throughout the city of San Francisco. While research shows that Black ...

Identifying Past Crop Switching In The Contiguous United States: Where Farmers Are Adapting To Changing Conditions, Christopher Brittain

Food Systems Master's Project Reports

Crop switching, which occurs when a novel crop type is introduced to an agricultural plot, is an adaptation strategy that is used in response to a variety of social, economic, and environmental factors. While past studies have investigated the motivations behind crop switching and examined its role in mitigating future agricultural losses due to climate change, understanding of where crop switching has occurred in the United States is more limited. In this paper, I develop a method of identifying the individual plots on which crop switching occurred in the contiguous United States. This method uses the Cropland Data Layer from ...


Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws 2022 University of Nebraska-Lincoln

Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws

Dissertations & Theses in Natural Resources

Marginal cropland is suboptimal due to historically low and variable productivity and limiting biophysical characteristics. To support future agricultural management and policy decisions in Nebraska, U.S.A, it is important to understand where cropland is marginal for its two most economically important crops: corn (Zea mays) and soybean (Glycine max). As corn and soybean are frequently planted in a crop rotation, it is important to consider if there is a relationship with cropland marginality. Based on the current literature, there exists a need for a flexible yet robust methodology for identifying marginal land at different scales, which takes advantage ...


Assessing Urban Canopy Program In Redlands California, Joseph Angel Rocha IV 2022 California State University, San Bernardino

Assessing Urban Canopy Program In Redlands California, Joseph Angel Rocha Iv

Electronic Theses, Projects, and Dissertations

Climate change can cause major environmental and human health issues especially in lower income and minority communities (Ros et al. 2020; Bethel et al. 2022). Although studies note tree coverage alone cannot solve all climate related problems (Pataki, et al. 2021; Ross, 2021), tree coverage does provide alleviation for climate change related factors (Free-Smith, et al. 2004). Some ways trees can combat climate change is through improved air quality, improved water quality, and decreasing impacts of Urban Heat Island Effect (UHIE) (Nowak et al. 2018; Liu, Liu, 2021; Wang, Zhao, et al 2017). Although throughout the United States there is ...


Reexamining The Desert: A Study Of Place-Based Food Insecurity, Morgan Ryan 2022 University of Nebraska-Lincoln

Reexamining The Desert: A Study Of Place-Based Food Insecurity, Morgan Ryan

Theses and Dissertations in Geography

Food Deserts are areas where individuals lack access to healthy and affordable food. Since 1995, the United States Department of Agriculture has been one of the leading organizations studying the phenomenon of food deserts. However, issues relating to the scale of their analysis limit their ability to gain a nuanced understanding of food insecurity. In the past decade, an increased emphasis has been placed on the importance of local factors that contribute to food insecurity and complicate the large-scale study of the phenomenon. This research explores the various place-based factors shaping food insecurity in Lincoln, Nebraska, by readapting Penchansky and ...


The Plague And The Parthenon: Crusade, Climate Change And Disease In The Early Modern Mediterranean, John Mark Nicovich 2022 University of Southern Mississippi

The Plague And The Parthenon: Crusade, Climate Change And Disease In The Early Modern Mediterranean, John Mark Nicovich

Master's Theses

The present study examines the role epidemic diseases, specifically malaria and bubonic plague, played on the course of the Morean War (1684-1699). The Morean War was a major offensive by Christian powers, led by the Venetian Republic, against Ottoman controlled Greece. Christian victories during the war were widely celebrated across western Europe, but even in victory Christian forces took severe casualties from multiple disease outbreaks. First, this study seeks to explain the terrestrial and maritime networks the war was fought over, and how those networks either led the opposing forces into regions of endemic disease (malaria), or how they allowed ...
