Evaluation Of Staten Island's Wetland Services And Environmental Costs Of Removal, Gracyn Cole

Arts & Sciences Undergraduate Showcase

In 2017, the New York City Council approved a zoning variance allowing the demolition of 28-acres of wetlands near Staten Island’s Graniteville neighborhood in order to build a BJ’s Wholesale grocery store, a gas station, and a parking lot for 835 cars. This action raised concern for the people living within this neighborhood due to the amount of water detention the wetlands provide during natural disaster events. Specifically, the Graniteville Wetlands have protected the surrounding neighborhoods from severe natural disasters such as Hurricane Sandy which, in turn, has allowed these neighborhoods to contribute less to flood mitigation through infrastructure and …

Lake Satellite Temperature Data Validation, Mamadou Balde, Pascal Kouogang

Publications and Research

In environmental remote sensing, satellite data isn't absolutely conclusive, for that reason, there is a natural need to verify the data acquired from the satellite. The most suitable tool to achieve such verification is on ground sensors that have the advantage of proximity. Addressing any possible discrepancies between the satellite data and the ground sensor data is sure to yield ways to come up with improvements of satellite band calibration and sensing capabilities. This research focused on correlating temperature data from the MODIS satellite with the data obtained from the In Situ sensor located in Lake Sunapee. Doing the latter …

Climate Model Skill At Simulating Large-Scale Atmospheric Circulation Patterns And Associated Temperature And Precipitation Over The Pacific Northwest, Graham Taylor

Student Research Symposium

The ability of the latest state-of-the-art suite of climate models to simulate observed large-scale atmospheric circulation patterns over the Pacific Northwest of North America is evaluated. Twelve representative patterns of atmospheric circulation are identified using machine learning applied to observational data. Climate model data from simulations of the historical period are mapped to each observational-derived pattern, and the resulting differences between patterns, as well as differences in frequency of pattern occurrence, are quantified. In general, models are able to simulate the range of circulation patterns with reasonable accuracy, although model skill varies to some degree across the 25-member climate model …

What Can We See From The Road? Applications Of A Cumulative Viewshed Analysis On A Us State Highway Network, Sterling D. Quinn

Geography Faculty Scholarship

In many parts of the world, motorized travel is one of the most common ways that people interact with their regional landscape. This study investigates how travelers' understandings of place might be influenced by what landforms they can see from a vehicle. It uses a cumulative viewshed analysis on the Washington State (United States) highway network to determine which physical landscape features are most frequently visible or obscured from the road. Adapting ideas from Kevin Lynch's The Image of the City, I propose spatial data processing methods to derive landmarks, edges, and districts that could most contribute to the mental …

Blue Zones: Unlocking Key Themes In The Centenarian's Life, Grace Beer, Grace O. Beer

Honors College Theses

Longevity has been sought after in certain areas of the world, and there are specific regions where this has been achieved. There is an American average life expectancy of 72 years old, but individuals in “Blue Zones” here in America and other areas of the world are expected to and have proven to live well beyond 100. The areas of Okinawa, Sardinia, Nicoya, Ikaria, and Loma Linda are classified as Blue Zones, and there could be more of an understanding of how these people live the way they do to have such healthy physical outcomes. To deeply understand the strategy …

The Demotechnic Index Of Nations, 1980-2018, Camden Rainwater

Geosciences Undergraduate Honors Theses

The Demotechnic Index (DI) is a non-dimensional metric that is the scalar multiple of energy consumption over and above that required for mere subsistence of a national population. Thus, the DI is a measure of energy efficiency that scales a country’s industrial energy consumption (called the total technological energy) and the energy required to meet the metabolic demand of the population (called the total metabolic energy). The DI was created by scientist John Vallentyne in 1982, refined in 1994, but never gained popularity or wide use as a sustainability metric. The objective of this thesis was to re-evaluate the DI …

Historical Underpinnings And Consequent Effects Of Labor Exploitation Of Mexican And Central Americans In The United States, Andrew Elkins

World Languages, Literatures and Cultures Undergraduate Honors Theses

The experience immigrants have today working and living in the southern United States is defined by systems that have developed out of lingering racist attitudes and reactions toward these individuals. The flow of people across the U.S.-Mexico border has a long history, and it is characterized by patterns that have continued from early guest worker programs to the present-day flow of migrants, both legal and undocumented. Also continually present is the racialization of these migrants, which has often forced them to work and live as marginalized members of American society. This project will explore the establishment of Mexican American citizen …

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

Department of Geography: Dissertations, Theses, and Student Research

Food deserts are areas where individuals lack access to healthy and affordable food. Since 1995, the United States Department of Agriculture (USDA) 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 …

Data-Driven Framework For Understanding & Modeling Ride-Sourcing Transportation Systems, Bishoy Kelleny

Civil & Environmental Engineering Theses & Dissertations

Ride-sourcing transportation services offered by transportation network companies (TNCs) like Uber and Lyft are disrupting the transportation landscape. The growing demand on these services, along with their potential short and long-term impacts on the environment, society, and infrastructure emphasize the need to further understand the ride-sourcing system. There were no sufficient data to fully understand the system and integrate it within regional multimodal transportation frameworks. This can be attributed to commercial and competition reasons, given the technology-enabled and innovative nature of the system. Recently, in 2019, the City of Chicago the released an extensive and complete ride-sourcing trip-level data for …

Addressing The Scale Issues In Spatial-Temporal Analysis Of Crime : An Integrative Framework And Empirical Findings, Mohammed Abdulrazak Alazawi

Legacy Theses & Dissertations (2009 - 2024)

Based on a critical review of existing literature in the spatial-temporal analysis of crime, three challenges have been identified: spatial-temporal scaling, theorizing spatial patterns for different types of crime, and the micro interaction between space and time. The spatial-temporal scaling issue is related to choosing the appropriate geographic unit of analysis. The theoretical issue concerns the lack of an integrative approach that can integrate the benefits of each theoretical perspective and identify broader processes to explain the resulting spatial patterns for different types of crime. Also, examining and explaining the variation of the micro space-time interactions for different types of …

Prescribed Burning And Land Functions In The Mixed-Land Use Management Of The Berea College Forest., Hinzee Smith

College of Arts & Sciences Senior Theses

The Berea College Forest is the oldest privately managed forest in Kentucky. Spanning over 9,000 acres, the forest provides opportunities for hiking, timber production, carbon sequestration, education, and much more. The Berea College Forest is uniquely situated as it is mere miles from the town center of Berea and Berea College. This proximity to a concentrated population causes the management of the forest to be observed and experienced by the community members, where accessibility to trails, hosted events, and educational experiences extend the land functions of the managed forest to community members in more direct ways than other publicly managed …

Indians In The Archives: A History Of Native Americans, Pakachoag Hill And Holy Cross, 1674-1973, Jack Hynick

Of Life and History

Native people are conspicuously absent from the official and popular history of the College of the Holy Cross. Extant records from the Holy Cross archives, the American Antiquarian Society, and digitized reports from the Commonwealth of Massachusetts are filled with references to Native people at Holy Cross and the surrounding Worcester area. By addressing the history of the land, the experiences of Native people on Pakachoag Hill, the roles played by Holy Cross community members in settler colonialism, and the use of Native imagery, this paper hopes to correct a blinding omission in the story of the College.

Multi-Decadal Analysis Of Remotely Sensed Vegetation Change In Berea College Forest - Seasonality Of Forest Patterns Using Remote Sensing., Jacob Foushee

College of Arts & Sciences Senior Theses

Satellite imagery is a practical and valuable tool for monitoring vegetation condition in forests. The longevity of the USGS/NASA Landsat program along with its medium spatial resolution (30m) gives researchers the ability to make informed statements on land cover generally, and specifically on aspects such as forest conditions. The Landsat program’s nearly 50-year archive of imagery show how Earth’s surface has changed through modern development and how these developments have influenced forests. Google Earth Engine (GEE) is a cloud-based repository of satellite imagery dating as far back as the 1970s. This study utilizes Landsat 5-8 imagery from GEE to calculate …

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 …

Multi-Trophic Biodiversity Increases With Increasing Structural Complexity Of Forest Canopy, Ayanna St. Rose

Graduate Theses and Dissertations

Understanding the effects of forest canopy structural complexity on multi-trophic diversity is critical for conserving biodiversity and managing land sustainably. But multi-trophic diversity is often ignored when making decisions about land management due to lack of cost- and time-effective methods to evaluate it. Here, we explored a new method based on widely available remote sensing data to quantify canopy structural complexity and its relationships with multi-trophic biodiversity at landscape scale using 32 forested sites of the National Ecological Observatory Network. We investigated the influence of vertical and horizontal structural complexity of forest canopy on multi-trophic (primary producers, herbivores (beetles), omnivores …

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

School of Natural Resources: Dissertations, Theses, and Student Research

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 …

Food Security And Dietary Diversity Among Conventional And Organic Tea-Smallholders In Central And Southern Sri Lanka, Nethmi Bathige

Geography Honors Projects

In Sri Lanka, smallholder tea producers grow 70 percent of the country’s tea and bring in significant export earnings. However, when the country moved towards a more liberalized economy in the 1970s, growing cash crops such as tea for exports increased. As a result, there was a cut-back in food crop agriculture as farmers made space to grow more commercial crops. This research treats tea smallholder households as a unit of study. It looks at how economic status (average income and wealth rankings), level of crop diversity, and method of tea farming (organic or conventional) have influenced food security and …

Analysis Of Gentrification And Green Spaces In East Austin, Texas, Carly Fordyce

Graduate Theses and Dissertations

Gentrification, the urban process that results from uneven development within cities, can cause unjust displacement of traditional, low-income residents in residential neighborhoods, and inequitable access to community services and benefits. Because of the negative social impacts that gentrification can have, many local governments and agencies have been known to attempt to mitigate changes by initiating different types of planning policies. Such policies usually apply changes in housing or zoning rules to enable lower-income residents to have access to housing and community amenities in the area. Another aspect resulting from gentrification that local government will try to rectify is low access …

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 …

Toward Global Localization Of Unmanned Aircraft Systems Using Overhead Image Registration With Deep Learning Convolutional Neural Networks, Rachel Linck

Graduate Theses and Dissertations

Global localization, in which an unmanned aircraft system (UAS) estimates its unknown current location without access to its take-off location or other locational data from its flight path, is a challenging problem. This research brings together aspects from the remote sensing, geoinformatics, and machine learning disciplines by framing the global localization problem as a geospatial image registration problem in which overhead aerial and satellite imagery serve as a proxy for UAS imagery. A literature review is conducted covering the use of deep learning convolutional neural networks (DLCNN) with global localization and other related geospatial imagery applications. Differences between geospatial imagery …

Transforming Trees, Transcending Binaries: Gender In Augustan Poetry, Kendall Swanson

College Honors Program

Humans have been inextricably linked to nature since before the rule of Emperor Augustus in Ancient Rome. Nature feeds humans, it gives people the tools to build a society. Because of this relationship, it is no surprise that authors, both ancient and modern, incorporate various themes of the natural world into their works. Additionally, nature appears linked to human conceptions of gender, as seen in literature and real-world experience. According to the United Nations, one goal to accomplish in order to achieve sustainable development is gender equality in all countries. Gender and nature work together: when inequality exists, environmental degradation …

Unpacking The Environmental Movement In Megacity Dhaka: How Does The Resource Mobilisation Theory Explain Local Urban Complexity?, Saleh Ahmed

Global Studies Faculty Publications and Presentations

In the Global South, urban policies are heavily influenced by colonial heritages, and people often experience citizens-detached urban development initiatives. The environmental movement is seen as a new addition that might contribute to society’s efforts to achieve equal urban environmental opportunities. The geographical focus of this article is the megacity Dhaka, which is the social, political, and economic capital of Bangladesh. Unfortunately, this hyper-urbanised megacity suffers from a large poverty-stricken population, leading to a gap in environmental services between the poor and rich. In recent years, Dhaka has experienced a growing momentum with the environmental movement, demanding environmental rights and …

The Value Of Education: School Policy Decisions During The Covid-19 Pandemic, Elika W. Somani

Individually Designed Interdepartmental Major Honors Project

During the COVID-19 pandemic, lacking national U.S. policies, wide variation and conflict over chosen public school policy decisions emerged. What factors and guidelines informed the decision-making process in K-12 public schools during the COVID-19 pandemic and who were the key stakeholders? This study examines three school district types – a large city, medium city, and small-town – across Minnesota as case studies to unpack how policy decisions were made during the pandemic. Stakeholder interviews uncovered that the school decision-making process was a) connected to a district's political opinions, b) made by the superintendent and school board, c) primarily influenced by …

Composite Style Pixel And Point Convolution-Based Deep Fusion Neural Network Architecture For The Semantic Segmentation Of Hyperspectral And Lidar Data, Kevin T. Decker, Brett J. Borghetti

Faculty Publications

Multimodal hyperspectral and lidar data sets provide complementary spectral and structural data. Joint processing and exploitation to produce semantically labeled pixel maps through semantic segmentation has proven useful for a variety of decision tasks. In this work, we identify two areas of improvement over previous approaches and present a proof of concept network implementing these improvements. First, rather than using a late fusion style architecture as in prior work, our approach implements a composite style fusion architecture to allow for the simultaneous generation of multimodal features and the learning of fused features during encoding. Second, our approach processes the higher …
