Understanding University-Level Food Recovery Programs’ Approaches To Minimizing Food Waste While Combating Food Insecurity In The United States, Ella F. Flesher

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Food is wasted every day at each level of the food system from production to consumption. This surplus has significant negative impacts on the environment after food is sent to the landfill and allowed to rot. However, some surplus food can be repurposed and diverted from the landfill. This study served as an initial investigation to explore multiple food waste diversion programs and analyze their structure, best practices, and methods to divert leftover food. This study specifically aimed to compare and contrast food recovery programs by interviewing participants from three food recovery programs from different university institutions. With the key …

The study will employ statistical techniques to evaluate this association while accounting …

Repurposing Old Railways To Enhance Recreation And Ecological Services, Carter Versaevel

Celebrating Scholarship and Creativity Day (2018-)

We are currently facing what can only be described as a biodiversity crisis. Species are disappearing faster than ever before, largely due to habitat fragmentation caused by humans. How can old railroads be repurposed into recreational trails that can also help improve biodiversity and ecological function? By turning old derelict tracks into “green trails,” these tracks can be given new life and help reverse the effects of fragmentation, while providing recreational services to nearby communities.

Photochemical Transformations Of Crude Oil In Marine Environments: Temporal And Thermal Dynamics Of Oxygenated Photoproducts And Genotoxic Effects, Mohamed Elsheref

LSU New Orleans Theses and Dissertations

This dissertation investigates the photochemical transformation of different crude oil types in marine environments, focusing on the time and temperature dependency of the formation of oxygenated photoproducts and their potential genotoxic effects. Using electrospray ionization tandem mass spectrometry (ESI-MS/MS), we examined the time and temperature dependence of aldehyde and ketone oxocarboxylic acid photoproduct generation from crude oil-seawater systems under simulated solar irradiation. The study revealed a near-linear increase in photoproduct concentration over an 18-hour irradiation period, with production rates ranging from 0.6 to 69 µmol/hm² of oil surface. Temperature effects on photoproduct formation were complex, but generally showed increased total …

From Farm Town To National Acclaim: Carmel, In As A Showcase Of New Urbanist Design And The “Holistic” Growth Machine, Owen James Beute

Undergraduate Honors Thesis Collection

Carmel, Indiana has been an anomaly in terms of entire transformation of a city's design and identity over the span of the last thirty years. This research aims to situate Carmel's development process into the urban planning theories of New Urbanism and the "growth machine" thesis, as well as telling Carmel's development story as a narrative of key events. Research focuses on the dynamic between the key aspects of New Urbanism - sustainability, livability, and human-scale growth - and the "growth machine" thesis which frames urban growth as a detrimental process focused on generating wealth solely for the decision makers, …

Career Aspirations And Gender Norms: How Socialization Influences Women’S Professional Choices, Emily Rose Hunt

Undergraduate Honors Thesis Collection

While legal frameworks grant women equal rights and opportunities to participate in any occupation, gender inequality continues in part due to the persistent gender segregation within the workforce. Gender socialization places women into roles that limit their occupational opportunities, so this study explores women’s understanding of their career options based upon the potential constraints that come from their identity as a woman. This study uses a qualitative approach, using semi-structured interviews conducted with students at Butler University to gather information on women’s personal perspectives on how their gender impacted their perceived career options. A sample of nine undergraduate women were …

Looking Green: A Rhetorical Analysis Of Greenwashing In Fossil Fuel Advertisements, Elizabeth Schohn Hein

Undergraduate Honors Thesis Collection

The world’s leading oil and gas companies knew the impact of fossil fuels on climate change as early as the late 1970s. Despite this knowledge, the fossil fuel industry proceeded to invest money in publicly denying the link between burning fossil fuels and climate change. There is increasing hindrance by American consumers towards fossil fuels as the consequences of their extraction and production become more glaring and evident in the environmental destruction and consequences of climate change across the globe. Growing environmental concerns about the impacts of fossil fuels, like oil and natural gas, from the general public resulted in …

Critically Assessing Normative Methods And Their Limitations In Managing Crowding Within Parks And Protected Areas, Glendon R. Vansandt

All Graduate Theses and Dissertations, Fall 2023 to Present

Visitor experiences in parks and protected areas are shaped by a variety of environmental, managerial, and social factors. To ensure that visitors enjoy their time in these spaces, management agencies often adopt guidelines to establish acceptable levels for different aspects of these experiences. One of the most selected factors is perceived crowding, which reflects how crowded visitors feel in a given area. When perceived crowding exceeds desired levels, it can significantly diminish visitor satisfaction.

This thesis presents two studies aimed at identifying the shortcomings of the management of perceived crowding. The first study conducts a comprehensive literature review that identifies …

Querying The Ecological Sublime: Colonial Aesthetics, Anticolonial Thought, And The ‘Double Fracture’, Tacuma Peters

Publications and Research

This article examines the ecological sublime in its relationship to the history of colonial aesthetics, anticolonial thought, and contemporary colonialism. It argues that, while Edmund Burke utilized the sublime in support of colonialism (including settler colonialism) in North America and colonial slavery, Samson Occom and Ottobah Cugoano developed versions of the sublime to contest British colonialism in the Americas. The history of this aesthetic contestation has not been represented in scholarship on the ecological sublime, which, this article shows, has a vexed relationship with historical and contemporary colonialism. The article argues that the ecological sublime exhibits the “double fracture” of …

Environmental Racism In Our Backyards, Elizabeth Sanchez

Collective Drip: Transformation, Hybridity, And Queer Ecologies, Vee Adams

LSU New Orleans Theses and Dissertations

In my recent body of work, Collective Drip, I investigate the queer and trans body as a site for transformation. Through the lens of queer theory, ecology, and myth, I explore what it means to be becoming, always in process. Looking at hybrid bodies and symbiotic life forms, I’m interested in investigating what it means when the body is seen as a dynamic landscape? What happens when the community is reinvisioned as an ecosystem? Facing the current transphobic political landscape, this body of work offers queer and trans visions of pleasure and abundance.

Adapting To Climate Change: Outdoor Recreation Impacts In New Hampshire, Visitor Coping Behaviors, & Provider Management Strategies, Madeleine Smith

Doctoral Dissertations

As of 2023, outdoor recreation participation in the United States (U.S.) reached a 15-year high, generating $1.2 trillion in economic output and supporting 5 million jobs. Concurrently, the contiguous U.S. experienced earth surface temperatures averaging above the 20th-century norm for the 27th consecutive year. Climate change presents increasing challenges for outdoor recreation, particularly in the Northeast and North Central U.S., where seasonal shifts, extreme weather events, and resource degradation are projected to acutely impact recreation patterns and management needs. New Hampshire (NH), where nearly 30% of the state is safeguarded for public use, relies heavily on outdoor recreation. As of …

Railroads And Recreation In Minnesota, Carter Versaevel

Celebrating Scholarship and Creativity Day (2018-)

This map shows outdoor recreation areas along with the most populated cities and all railroads in Minnesota. I wanted to find out what areas were most in need of outdoor recreation opportunities and how to provide those opportunities. I found that railroads and high population cities were concentrated together. These areas had little access to outdoor recreation. These railroads can be turned into trails to provide much-needed recreation to a large number of people. I created this map using data I acquired through a formal request to the Minnesota Department of Transportation. I used the Minnesota Department of Natural Resources’ …

Exploring Variability Factors In Bur Oak Morphology, Karyn Morrissey

Celebrating Scholarship and Creativity Day (2018-)

This project, completed for Dr. Kate Cary in the Biology department, investigates how bur oak (Quercus macrocarpa) leaf morphology varies geographically. Using digitized herbarium specimens and provided data which included latitude, longitude, collection moth and year, leaf dissection, petiole length, temperature, and precipitation, the project visualizes patterns in morphology with a focus on leaf dissection (cm). Maps were generated both at the state level (Minnesota) and national level, depicting bur oak locations and morphology trends across different seasons (January-May and June-December) over the past century.  The importance of this data lies in its ability to reveal how environmental factors like …

Fish Need Shelter Too! The Importance Of Mangroves In An Aquatic Ecosystem, Karyn Morrissey

Celebrating Scholarship and Creativity Day (2018-)

Mangrove trees exhibit many adaptations to living in salt water and tend to be found along marine shores. Some of these features include the ability to have their roots constantly submerged in water and stilt roots. Stilt roots are not true roots, instead they grow from the stem to the ground and provide both height and mechanical support in a somewhat fluid soil that the plants grow in. These stilt roots are thought to provide sanctuary for many juvenile fish. During our time on San Salvador Island, Bahamas (March 2025), we hypothesized that there was a relationship between distribution of …

Sediment And Debris Flows Resulting From The 2020 El Dorado Wildfire, San Bernardino Mountains, California, Andrew Suarez

Electronic Theses, Projects, and Dissertations

The Yucaipa Ridge is a section of the San Bernardino Mountains within the Transverse Ranges of Southern California. During the summer and early fall of 2020, Yucaipa Ridge experienced severe vegetation damage from both the Apple and El Dorado wildfires. Burned slopes exhibit a higher susceptibility to geomorphic change within several years of burning from the introduction of meteoric water onto the slope. Yucaipa, Oak Glen, and other nearby communities are currently at risk of damage by hyperconcentrated flows and debris flows during the seasonal rainy season.

Debris flows and hyperconcentrated flows (a.k.a. mudflows; are grouped and referred to in …

The Impact Of Green Credit Ratio On Return On Assets, Liao Wang

All Theses

How does the green credit ratio affect a bank return on assets? This study uses panel data from 2012 to 2019, covering 18 large banks in China, including 6 state-owned banks and major 12 important joint-stock and city commercial banks. I use regression models to measure the effect of the green credit ratio (GCR) on return on assets (ROA) and return on equity (ROE), and we focus on how bank ownership and fixed effects matters.

The results show that the effect of green credit ratio (GCR) on ROA depends on the model design. When bank fixed effects are included, green …

The Proverbial Milk And Honey: Frontier, Racial Lines, And The Development Of California Foodways, Ahlys Gandara

Electronic Theses, Projects, and Dissertations

This thesis proposes that the development of foodways in the state of California occurred concurrently with the development and failures of Americanization and the American frontier. This is done with respect to the fact that California has a much longer history than that of the United States. While foodways are often discussed and examined within the ideas of nationalization, this becomes harder to do within the United States as there is no unifying idea of a national identity and any attempts to do so were hampered by the lack of consensus as to a singular identity. This is especially true …

Private Conservation And Indigenous Groups With Contested Identities: How Are Land Trusts Navigating Recognition Politics And Controversy?, Geneva Nuttall Lish

Master's Theses and Capstones

New Hampshire has no state or federally recognized Indigenous tribes, and the identities of its self-recognized Abenaki tribes have been publicly contested by Canadian scholars and the Odanak and Wolinak First Nations. As a result, conservation practitioners within New Hampshire land trusts face challenges in making decisions about collaborations, cultural access, and land management involving tribal entities. Our research thus explores how land trusts currently incorporate Indigenous relationships in their operations, and how these practices may be affected by (a) an absence of tribal federal recognition and (b) the publicly contested nature of a tribe. We conducted six semi-structured interviews …

High Frequency Analysis Of The Carbon Dioxide Linkage Between Terrestrial And Aquatic Ecosystems, Amanda G. Theall

Master's Theses and Capstones

Carbon dioxide (CO2) is a potent greenhouse gas, and surface water concentrations are often supersaturated relative to the atmosphere. To fully quantify CO2 dynamics in stream ecosystems, it is critical to understand sources of stream CO2, particularly the link between terrestrial and aquatic ecosystems. It is unclear how soil CO2 enters streams and to what magnitude. To address this knowledge gap, I analyzed high-frequency CO2 time-series of soil and stream water sensor data to understand source-sink dynamics and time lags between the two pools. I used seven years of hourly sensor data from three soil depths with upscaled 15-minute stream …

Post-Fire Debris Flow Initiation Potential Based On Forensic Analysis Of Debris Flow Occurrence From The 2020 El Dorado Wildfire On Yucaipa Ridge, San Bernardino County California, Seth Clemen D. Saludez

Electronic Theses, Projects, and Dissertations

This study focuses on the potential debris flow initiation and effect in areas affected by the El Dorado Fire in the Southern San Bernardino Mountains. It uses novel technology combining drone-based photography and LiDAR imaging to create surface models of areas where potential debris flows could initiate, flow, and be deposited. The scans were repeated as geomorphic change occurred through the wet season to document spatial and volumetric changes resulted from the flows. These measurements were combined with traditional fire assessment and observational methods to characterize pertinent conditions.

As we investigated potential debris flow risk in this study area, we …

The Human Legacy: Agriculture, Civilizations, Strife, And Pandemics Changing Our Climate, Jacalyn M. Wittmer Malinowski

Climate Change and the Individual, 2025-26

For most of human history, climate has shaped our lives, while our influence on it remained minimal. However, the notion that early humans had no measurable impact on the climate before industrialization is inaccurate. Early in human history, activities – such as the rise of agriculture, the growth of civilizations, periods of conflict, and pandemics – altered greenhouse gas levels in the atmosphere. These changes contributed to significant periods of climate change long before the burning of fossil fuels set us on the path to today’s global climate crisis.
