Rice Biomass Response To Various Phosphorus Fertilizers In A Phosphorus-Deficient Soil Under Simulated Furrow-Irrigation, Jonathan B. Brye, Kristofor R. Brye, Diego Della Lunga

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Wastewater-recovered phosphorus (P), in the form of the mineral struvite (MgNH4PO4∙6H2O), may provide a sustainable alternative to decreasing rock-phosphate reserves. Struvite can be generated via precipitation methods, potentially reducing the amount of P runoff to aquatic ecosystems. The objective of this greenhouse tub study was to evaluate the effects of chemically and electrochemically precipitated struvite (CPST and ECST, respectively) on aboveground plant response in a hybrid rice cultivar grown using furrow-irrigation compared to other common fertilizer-P sources [i.e., triple super phosphate (TSP) and diammonium phosphate (DAP)] using three replications of fertilizer treatment in a P-deficient silt loam (Typic Glossaqualfs). Aboveground …

"Our Loons": Participant Attachments And Motivations Within A Community-Based Monitoring Program, Taylor Tewksbury

Graduate Student Theses, Dissertations, & Professional Papers

Organizations can benefit from understanding person-place relationships and volunteer motivations as they recruit and sustain involvement in their community-based monitoring (CBM) programs. Place attachment, or the bond between people and their meaningful environments, is one lens through which to explore these relationships. Past studies have associated place attachment with environmentally responsible behaviors (ERB), such as CBM involvement. However, few studies have explored the relationship between place attachment and CBM in the context of volunteers’ attachment to the species of study.

The purpose of this research study was to explore the place-based relationships and motivations among volunteers of the Loon Preservation …

The Vital Role Of Dehcho Dene Knowledges In Climate Change & Permafrost Thaw Adaptation In Jean Marie River First Nation Nwt, Mackenzie Bell

Theses and Dissertations (Comprehensive)

Across the globe climate change has become an issue of growing concern for both Indigenous and non – Indigenous peoples alike. In Northern Canada this narrative is no different. For Indigenous groups such as the Jean Marie River First Nation (JMRFN) anthropogenic climate change is not only a reality but is visible through their daily interactions with the environment around them. Additional insight pertaining to these climatic changes and their impacts can be found through analyzing the traditional knowledge systems of the JMRFN and how these before mentioned interactions have changed over time. This two-year participatory research project has investigated …

A Comprehensive Satellite-Based Assessment Across The Pacific Arctic Distributed Biological Observatory Shows Widespread Late-Season Sea Surface Warming And Sea Ice Declines With Significant Influences On Primary Productivity, Karen E. Frey, Josefino C. Comiso, Larry V. Stock, Luisa N C Young, Lee W. Cooper, Jacqueline M. Grebmeier

Geography

Massive declines in sea ice cover and widespread warming seawaters across the Pacific Arctic region over the past several decades have resulted in profound shifts in marine ecosystems that have cascaded throughout all trophic levels. The Distributed Biological Observatory (DBO) provides sampling infrastructure for a latitudinal gradient of biological "hotspot" regions across the Pacific Arctic region, with eight sites spanning the northern Bering, Chukchi, and Beaufort Seas. The purpose of this study is two-fold: (a) to provide an assessment of satellite-based environmental variables for the eight DBO sites (including sea surface temperature (SST), sea ice concentration, annual sea ice persistence …

Inequitable Distribution Of Plastic Benefits And Burdens On Economies And Public Health, Rachel Karasik, Nancy Lauer, Anne-Elisabeth Baker, Niki E. Lisi, Jason A. Somarelli, William C. Eward, Kathinka Fürst, Meagan M. Dunphy-Daly

Faculty Scholarship

Plastic heterogeneously affects social systems – notably human health and local and global economies. Here we discuss illustrative examples of the benefits and burdens of each stage of the plastic lifecycle (e.g., macroplastic production, consumption, recycling). We find the benefits to communities and stakeholders are principally economic, whereas burdens fall largely on human health. Furthermore, the economic benefits of plastic are rarely applied to alleviate or mitigate the health burdens it creates, amplifying the disconnect between who benefits and who is burdened. In some instances, social enterprises in low-wealth areas collect and recycle waste, creating a market for upcycled goods. …

Connecting Antibiotic Resistance To The Environment (Care): Introducing A Novel Framework Integrating Chemical Cross-Resistance And Place-Based Engagement To The Blue Marsh Watershed In Reading, Pennsylvania, Jill Felker

Antioch University Dissertations & Theses

Antibiotic resistance is a serious health threat around the world. Millions of individuals are infected with antibiotic-resistant bacteria yearly, and thousands die from previously curable illnesses. Although antibiotic resistance occurs naturally, misuse of antibiotics accelerates the loss of their effectiveness. Public health campaigns focusing on antibiotic awareness have not effectively communicated and educated the public on this health crisis. New efforts to combat antibiotic resistance are urgently needed. This dissertation focuses on the ecological and public health components of antibiotic resistance research that must be addressed to decelerate antibiotic resistance. A new interdisciplinary theoretical framework was developed to Connect Antibiotic …

Eating Change: A Critical Autoethnography Of Community Gardening And Social Identity, Jessica Gerrior

Antioch University Dissertations & Theses

Community gardening efforts often carry a social purpose, such as building climate resilience, alleviating hunger, or promoting food justice. Meanwhile, the identities and motivations of community gardeners reflect both personal stories and broader social narratives. The involvement of universities in community gardening projects introduces an additional dimension of power and privilege that is underexplored in scholarly literature. This research uses critical autoethnography to explore the relationship of community gardening and social identity. Guided by Chang (2008) and Anderson and Glass-Coffin (2013), a systematic, reflexive process of meaning-making was used to compose three autoethnographic accounts. Each autoethnography draws on the author’s …

The Walls At The Ends Of Empires: Towards A Political Ecology Of The Imperial Border, Benjamin Allen Stahnke

Antioch University Dissertations & Theses

This dissertation study investigates the intricate and complicated interplay between the border walls of imperial states, environmental change, and dispossession. Employing a multidisciplinary approach rooted in Political Ecology, and drawing on the theoretical frameworks of Social Metabolism, Social Kinetics, and Green History, the study is built around an analysis of two historical examples: the Roman border walls in the north of England (Hadrian’s Wall and the Antonine Wall), and the U.S.-Mexico border wall. The research uncovers two overarching conclusions: firstly, imperial border walls serve as discriminatory structures, targeting and segregating Indigenous populations while asserting control over Indigenous geographies; secondly, the …

Diving To New Depths: An Exploration Of Aquarium Visitors' Reflection At A Shark Exhibit, Nicole Leigh Conklin

Antioch University Dissertations & Theses

Zoos and aquariums (Z/As) are conservation-oriented free-choice learning institutions. In order to support their mission of advancing wildlife conservation, Z/As deliberately design opportunities and experiences to meaningfully engage visitors in understanding, caring for, and acting on behalf of exhibited species. Conservation psychologists and practitioners have applied values-based and models of human behavior to design and evaluate experiences aimed to influence myriad cognitive, affective, and behavioral outcomes. However, there is little research exploring the role of and opportunity for reflection within these institutions. Models of reflection and reflective practice, which are rooted in both theory and empirical data, stress the importance …

Adaptive Regulation For Ecosystem Restoration: A Context For Effective Environmental Permitting, Jennifer M. Auger

Antioch University Dissertations & Theses

This dissertation investigates the regulatory challenges faced by large-scale ecosystem restoration (LSER) projects by exploring the perspectives of practitioners and regulators. Focusing on the federal regulatory permitting process, the study aims to understand its impact on LSER projects and proposes the application of adaptive regulation for improvement. Employing Q methodology, participants expressed their views on 34 statements related to wetland permitting for LSER projects. Factor analysis revealed two distinct perspectives: Factor 1 emphasizes the reorganization of the permitting process within existing regulations, advocating for more documentation and structured processes. Factor 2 highlights the need for restructuring both the permitting process …

Confluence: Evaluating The Individual Learning Outcomes Of A Combined Citizen Science And Environmental Education Project, Evan A. Harms

Graduate Theses, Dissertations, and Problem Reports (ETD)

Citizen Science has moved beyond a methodological tool for ecologists to crowdsource data to a novel platform for environmental and informal science education. However, few studies document the individual learning outcomes of citizen science as an educational tool, particularly in youth or extension education. This quantitative study focused on evaluating the individual learning outcomes of an environmental education and citizen science non-formal learning experience about water quality.

In this study, an existing lesson plan using four sequenced activities was adapted for use with West Virginia 4-H summer camps in 2022. Potential outcome areas were first identified from foundational environmental education …

Epistemological Insecurity In The Anthropocene, Dustin Purvis

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation analyzes how increased mainstream awareness of climate change and other complex environmental phenomena transforms some of the basic tools we use to understand the world, including notions of agency, evidence, and causality. More specifically, this project highlights numerous contemporary literary and cultural narratives that formally and thematically depict impromptu systems of action and comprehension developed by humans confronting the unique forms of information overload that result from damaged and rapidly changing environments. Following critics like Ulrich Beck, Rob Nixon, and Stacy Alaimo, I suggest our current era of ecological instability and destructive environmental practices dictate what I refer …

Mitigation And Preparedness In Disaster Communication: Examining The Need For Closing The Loop In The Discourse Of Renewal Theory, Abigail Renee Riggs

Graduate Theses, Dissertations, and Problem Reports (ETD)

Flooding across rural Appalachia has historically negatively impacted communities, and flood frequency is only expected to increase in the region as global temperatures rise. This indicates a need for effective disaster and crisis communication in flood-prone communities within the region. The discourse of renewal and readiness for renewal theories provide potential avenues for improving crisis and disaster communication. Readiness for renewal in particular focuses on closing the gap between the pre and post-crisis phases. However, readiness for renewal has yet to be applied to disaster communication and has not been studied qualitatively. Additionally, ethical guidelines for communication within renewal have …

Three Essays On Health And Environmental Economics: Applications Of Spatial Econometrics And Spatial Analysis, Mohammed Syedul Islam

Graduate Theses, Dissertations, and Problem Reports (ETD)

Spatial interaction and the locational structure between observations play key roles in the field of econometrics for both cross-sectional and panel data analysis. Compared to a non-spatial econometric model, a spatial model relaxes the assumption of independency in observations. This research applies spatial and non-spatial econometrics in three different fields of applied economics: (1) drinking water and air quality violations impacts on lung and bronchus cancer incidence in the contiguous United States (U.S.); (2) spillover effects of non-pharmaceutical interventions (NPIs) on COVID-19 cases across the contiguous U.S. counties; and (3) urbanization impacts on carbon dioxide (CO₂) emissions in …

Recommendations For The Operationalization Of A Loss And Damage Fund, Caelyn Smith

CMC Senior Theses

This thesis examines the several facets of the operationalization of the abstract and broad proposal of a “Loss and Damage Fund” following the 27th Conference of the Parties under the United Nations Framework Convention on Climate Change that took place in November of 2022. It examines the current mechanisms in place for developed nations providing climate finance to developing countries that are on the front lines of fighting a crisis heavily caused by historic reliance on and consumption of fossil fuels by wealthier, better-off nations. It delves into various criteria regarding which counties should share the burden and how much …

The Stateless Agent: A Multidisciplinary Analysis Of Transboundary Air Pollution In The El Paso-Ciudad Juárez Region Of The U.S.-Mexico Border, Elizabeth Hernandez

CMC Senior Theses

The El Paso-Ciudad Juárez (EPJ) region has a history of nonattainment for ozone and particulate matter. Given transboundary air pollution in the EPJ region is not confined to the U.S.-Mexico border, it is important to implement a transnational response that accounts for the health and safety of everyone, including marginalized communities in EPJ. This thesis assesses the state of air quality and transboundary air pollution in the EPJ region through a multidisciplinary perspective that focuses on issues of data monitoring, environmental governance, and transnational environmental justice. Analysis of the quantity and placement of ambient monitoring stations reveals EPJ residents near …

Evaluating Electric Bicycle Access In Us National Parks: Advantages And Controversy, Ben Rodman

CMC Senior Theses

Rising global temperatures are causing a higher likelihood of future climate disaster. Changes in personal behavior, that reduce the emissions driving this increase in global temperatures, contribute to the greater good. Electric bicycles (e-bikes) offer a viable option for individuals to reduce their personal contribution to this problem, while at the same time benefit from outdoor recreation. These benefits, along with affordability, are driving the current increase in popularity of this form of transportation. The COVID 19 pandemic fueled an increased interest in outdoor recreation, which in turn contributed to an increase in visitation at US National Parks. This thesis …

Renewable Portfolio Standards: Effectiveness And Carbon Implications, Alexander S. Albrecht

CMC Senior Theses

A renewable portfolio standard (RPS) policy is a popular regulatory tool implemented within the U.S. and abroad to limit energy sector emissions and incentivize renewable energy. Assessing their effectiveness and efficiency is a key component of achieving further reductions. We assess an energy market under an RPS using fixed-effects panel and 2SLS regression models to lend empirical credence to common theory-based concerns about RPS policy, namely (1) that they leave emissions unregulated once the RPS requirement is met and (2) that they do not incentivize full use of renewable energy resources. Our results show these to be valid concerns that …
