Book Review: Ecologies Of Inequity. How Disaster Response Reconstitutes Race And Class Inequality, Abel Traslaviña-Arias

Critical Disaster Studies

In Ecologies of Inequity: How Disaster Response Reconstitutes Race and Class Inequality, Sancha Doxilly Medwinter gathered diverse stories about how various migrant communities had to overcome not only disaster but also the overlapping networks established by those who were supposed to support them in 2012 in New York City. Medwinter portrays this contested post-disaster landscape through a thorough data recording of 120 individuals affiliated with various groups: racialized migrants or locals, tenants or property owners, local or external helpers, and those from wealthy or impoverished backgrounds. Ecologies of Inequity refer to the spatialized networks of organizational and interpersonal relations …

Environmental Beliefs Among Evangelical Leadership, Jeffrey Stark

Dissertations

There has been consensus among climate scientists for over a decade about the reality of human caused climate change. Even with this consensus, the public understanding of this issue remains divided based on factors generally unrelated to the science. Evangelical Protestants are one group which consistently polls as more skeptical of climate change. This is true not only when compared to the general population but also when compared to other religious demographics. Most large-scale surveys of evangelicals assume the demographic to be a monolith and do not attempt to break the demographic down further. In this mixed methods study, we …

The Price Of Priorities: How Human Choices Fuel Climate And Ecological Decline, Keisha Hickman

Biological Sciences Undergraduate Honors Theses

This thesis examines the ways in which human priorities and behaviors contribute to the escalating climate crisis and ecological systems. We will first analyze the role of social media in shaping public discourse on climate change and critically evaluate the priorities of institutions that have the means to assist in wildlife conservation. Both speak to the current behaviors of humankind prioritizing their own entertainment over meaningful efforts to mitigate climate change and preserve biodiversity. We will then shift to exploring the profound impact of human population growth and its associated activities on other species and ecosystems. Finally, the thesis will …

Linking Climate And Demography To Predict Population Dynamics And Persistence Under Global Change., Jennifer L. Williams, Amy L. Angert, Aldo Compagnoni, Ali Campbell, Megan L. Demarche, Margaret E K Evans, Joshua C. Fowler, Amy M. Iler, Jenna A. Loesberg, Allison M. Louthan, Scott W. Nordstrom, Multiple Additional Authors

Publications, Reports and Presentations

Predicting the effects of climate change on plant and animal populations is an urgent challenge for understanding the fate of biodiversity under global change. At the surface, quantifying how climate drives the vital rates that underlie population dynamics appears simple, yet many decisions are required to connect climate to demographic data. Competing approaches have emerged in the literature with little consensus around best practices. Here we provide a practical guide for how to best link vital rates to climate for the purposes of inference and projection of population dynamics. We first describe the sources of demographic and climate data underlying …

Evaluating The Preparedness Of Local Zoning Regulations For Flood Risk Reduction In The Most Affected Local Jurisdictions In Nebraska, Md Asaduzzaman Noor

Community and Regional Planning Program: Theses

Flooding has profound social, economic, and environmental impacts on local communities, and zoning plays a critical role in mitigating these risks. The 2019 Nebraska floods, among the most severe in the state’s history, highlighted the urgent need to strengthen local preparedness and mitigation strategies. This study assesses the extent to which local zoning regulations in Nebraska’s most affected jurisdiction, including rural areas, address flood risk reduction. A systematic review of 117 zoning ordinances from counties, cities, towns, and villages, we applied a structured analytical framework encompassing regulatory and permitting policies, voluntary and incentive-based measures, and nature-based solutions. The results show …

Groundwater Arsenic Contamination In The Oro Grande Wash, Dalila Boice

Electronic Theses, Projects, and Dissertations

This study investigates the distribution of naturally occurring arsenic in groundwater within the Oro Grande Wash in San Bernardino County, California. Depth-discrete groundwater quality data were collected over multiple years using nested and Westbay monitoring wells. Water quality results showed higher levels of arsenic in the deeper aquifers, ranging between 600 feet and 1,000 feet below ground surface. Arsenic levels in these regions reached as high as 66 µg/L. At roughly 800 feet and below, water quality data from the wells reveal that arsenic concentrations exceeded the 10 µg/L maximum contaminant level (MCL) in 87% of cases. These data provide …

Modeling Flood Risks For Small-Scale Coastal Watershed Across Shared Socioeconomic Pathway Scenarios, Sebastian Loschner

Graduate Theses and Dissertations (2019 - present)

Coastal flooding, driven by the mixture of natural processes and human activities such as precipitation, waves, sea level rise, and urbanization, remains a growing concern. While recent flood-risk studies use IPCC's Shared Socioeconomic Pathways with climate projections to assess future flood exposure, smaller coastal watersheds, < 120,000 acres, remain insufficiently studied. Projected sea level rise is expected to intensify these impacts in smaller systems, potentially causing more severe flooding than reported for larger watersheds. To address this gap, this study used the SRH-2D model integrated with Aquaveo's Surface-water Modeling System to simulate flooding in the lower Fish River basin, Alabama. A coastal watershed sensitive to both riverine and tidal influences. Simulations tested different sea levels based on SSP scenarios corresponding to low, moderate, and high emissions for the years 2050 and 2100. Results indicate that the midcentury scenarios remained even in inundation extent and volume, between 9.9-10.4% compared to the 2020 baseline, the latter scenarios had a wider range in results of between 25.9-50.3% compared to the same baseline. Across scenarios, the most vulnerable and inundated areas of the smaller coastal watershed were the narrow points where upstream flow convene with downstream backwater. These findings highlight the need for futuristic location-specific flood mitigation strategies.

Educating For Impact: A Prosocial Marketing Approach To Foster Altruism Among Young Consumers, Bela Florenthal

Journal of Applied Marketing Theory

This study explores how a prosocial marketing intervention in a dual-enrollment course fosters altruistic values and emotional development among young consumers while deepening their understanding of cause-related and social marketing. Grounded in holistic and experiential learning, the project required students to engage in weekly acts of kindness, reflect on their experiences, and share their actions on social media to amplify impact. Thematic analysis of qualitative data collected over two academic years revealed personal growth driven by intrinsic motivation (e.g., belonging, self-esteem) and positive emotions (e.g., joy, pride). Students demonstrated greater social awareness and practical application of marketing principles through volunteering, …

Evaluating Energy Transition Winners And Losers: Are Algae Biofuels Desirable, Feasible, And Viable?, Michelle M. Arnold

All Graduate Theses and Dissertations, Fall 2023 to Present

Climate change, environmental degradation, finite resources, and the uneven distribution of energy access all points to an urgent need for a global energy transition. But making that transition responsibly requires more than enthusiasm for “green” solutions—it demands careful evaluation of which energy sources are truly worth investing in. This dissertation develops a practical decision-making framework to help policymakers, scientists, and the public answer three foundational questions about any new energy technology: Is it desirable? Is it feasible? Is it viable? By systematically weighing public narratives, biophysical constraints, and patterns of innovation, the framework aims to prevent wasted time, funding, and …

General Human Environmental Sciences Faculty Publications and Presentations

Introduction Guided by attachment, social cognitive, and ecological systems theories, this study examined the direct and indirect effects of perceived parent-adolescent relationship quality on youths' conscious bias toward individuals facing socioeconomic or minority-related challenges.Methods Data were collected from 702 U.S. 18-year-olds via Qualtrics online panels. Measures included parent relationship quality, negative affect, human agency, and conscious bias (disregard for minority experiences and blaming attitudes).Results The findings revealed that strong parent-teen bonds indirectly influenced conscious bias through psychosocial wellbeing. However, while negative emotions were universally influential, the impact of human agency varied depending on gender and race/ethnicity.Discussion Study findings underscore the …

Indigenous Invisibility: Gaps In Education About Indigenous Peoples Among Environmental Decision-Makers, Brittany D. Hunt, Ryan E. Emanuel, David E. Wilkins, Shelly H. Wilkins

Jepson School of Leadership Studies articles, book chapters and other publications

Millions of Indigenous people belong to hundreds of Tribal nations and self-determined communities throughout the United States. Many of these groups continue to steward lands and waters that have shaped their distinct cultural and political identities since time immemorial. Increasingly, environmental professionals acknowledge the need to respect, understand, and defer to Indigenous knowledge about Earth's stewardship, but substantial barriers prevent full realization of these goals. One deep-seated barrier is a widespread deficiency in basic education about Indigenous peoples. Education on Indigenous peoples in schools is often fraught with two problems: erasure and stereotypes. Thus, students who pursue environmental careers often …

Innovation Curse: The Wastefulness Of Technologies Believed To Mitigate Climate Change, Minh Hoang Nguyen, Valoree Gagnon, Thanh Tu Tran, Thi Mai Anh Tran

Michigan Tech Publications

Technological innovations are increasingly promoted as solutions to climate change. However, many innovations, including Carbon Capture and Storage, bioplastics, and glacier geo-engineering, suffer significant limitations from high costs, speculative efficacy, and adverse ecological consequences. Using Granular Interaction Thinking Theory (GITT), a transdisciplinary framework grounded in information theory, quantum mechanics, and mindsponge theory, in this study, we explain how such technological innovations become systemically favored despite their flaws. We introduce the concept of the “innovation curse,” which arises when institutional and cognitive filtering systems, operating under high informational entropy, default to familiar but ineffective techno-solutions while marginalizing Indigenous and Local Knowledges …

A Triple Bottom Line Analysis Of Food Waste-To-Bioenergy At California University Campuses: Social Enablers Break Down Economic Barriers, Anjali Sharma

Master's Theses

Greenhouse gas emissions from food waste (FW) and energy generation are two major hurdles to the climate crisis. Previous research shows that waste-to-energy systems may provide a solution to both these challenges, particularly at university campuses, due to their high FW generation and high energy needs. Despite this, few academic institutions in California, US, have adopted waste-to-energy systems, and campus-specific challenges and opportunities associated with these systems remain underexplored. For this study, I use an Environmental, Economic, and Social (EES) lens to document the current landscape of FW management and implementation of food waste-to-bioenergy at campuses in each of the …

Doughnut Economics And Strong Sustainability: Rethinking The Role Of Financial Investment, Isabelle Pierotti

Electronic Theses and Dissertations

This thesis investigates how private investment could align doughnut economic framework. Doughnut economics is a strong sustainability economic framework where the economy operates within planetary boundaries while ensuring social equity. Theories of sustainable development, weak sustainability, and strong sustainability are discussed to provide theoretical context for doughnut economics and mainstream economics. The analysis concludes that conventional, profit maximizing private investment does not support a doughnut economics system by supporting the depletion of natural resources and exacerbating social issues. Sustainable mainstream investment also fails to support a doughnut framework. Lastly, while impact investment is theoretically committed to social and financial returns, …

Shifting Grounds Of Accountability: How Governmentality Reduces The Commoning Practices Of The Monpa Community In Arunachal Pradesh, Pijush Kumar Dutta

Journal of Law and Public Policy

Pastoralism is one of the traditional livelihoods of Monpa community that resides in western Arunachal Pradesh, India. They have been rearing yaks, an integral part of their culture and tradition, and managing summer and winter pasture lands as commons for grazing, However, the Monpa’s yak‑based livelihood is facing challenges as the number of villagers engaged in grazing related activities is reducing and the composition of livestock in the area is changing. To understand the reasons for these changes and its impact, an open‑ended questionnaire was used to interview herders, members of traditional village institutions and village panchayats, and elderly villagers …

Public Support For New Agricultural Best Management Practices To Protect Florida Water Quality, Sadie Hundemer, Madison A. Dyment, Matthew Gold

Journal of Extension

Recent research finds that changes to land management practices in geographically vulnerable areas of Florida could substantially reduce groundwater contamination; however, water quality improvement comes with tradeoffs. A change in land use or the adoption of new agricultural best management practices (BMPs) would have economic and cultural implications for farmers, rural communities, taxpayers, and the state as a whole. In two studies, we examined Florida residents’ support for alternative land management policy options, the considerations contributing to their policy preferences, and how preferences and considerations vary across demographic characteristics.

Navigating The Open-Loops: Actor Dynamics And Bottlenecks In The Transition Towards Circular Household Waste Supply Chains, Burcin Ozdamar, Aysu Göçer

Markets, Globalization & Development Review

Household waste supply chains (HWSCs) in developing countries often suffer from fragmented actor structures, weak coordination, and informal practices that limit their overall performance and circularity potential. Existing studies tend to focus on isolated aspects such as waste types, technologies, or individual actors, without systematically examining the broader network and interdependencies shaping HWSC outcomes. Addressing this gap, this study investigates the key components (e.g. actors and waste processes) and bottleneck points that hinder the structure and functioning of current HWSCs to transform into circular systems. Drawing on industrial network theory, the research analyzes how actor relationships and system configurations influence …

Optimizing Fleet Management: Evaluating The Feasibility Of Electric Vehicles And Leasing Strategies At The Utrgv Police Department, Van Edward Slusser

Doctoral Dissertations and Projects

The purpose of this applied dissertation was to improve readiness and cost discipline in a campus public-safety fleet and to assess the feasibility of electrification and leasing. A qualitative case-study design triangulated semi-structured interviews with stakeholders, administrative records (maintenance, fuel, costs), and telematics from eight vehicles to characterize duty cycles and constraints. Key findings were: stakeholders endorsed a phased, evidence-gated approach that relies on vehicle- and role-level analytics and coaching-based idle management; cost analysis supported availability-weighted replacement paired with warranty-anchored leasing to stabilize maintenance exposure and smooth appropriations; and telematics revealed role-differentiated patterns—administrative vehicles converted engine-on time to distance efficiently …

Power And Planning: A Critical Discourse Analysis Of Tribal And Non-Tribal Oregon Wildfire Protection Plans, Christian J. Heisler, Max Nielsen-Pincus, Douglas Deur, Gabe Sheoships

Environmental Science and Management Faculty Publications and Presentations

Background:

Since the late 1800s, the US government has largely removed Indigenous fire stewardship practices from the landscape by implementing a top-down fire suppression system that criminalized traditional fire practices and denaturalized the role of fire in forested environments. A century of routine fire suppression produced dense, homogenous forests capable of sustaining high-intensity wildfire that exceeds the suppression capabilities of land management organizations in many regions, spurring federal leaders to modify management approaches. As part of this change, numerous federal policies and plans have advocated for further involvement of Native American tribes and incorporation of Indigenous knowledge within management decisions. …
