Educational Influences On Environmental Perception: A Semester Analysis Of The New Ecological Paradigm Scale In Undergraduates, Zoe Zingler
Department of Environmental Studies: Undergraduate Student Theses
This study evaluated the impact of a geography course, GEOG 181: Global Environmental Issues, at the University of Nebraska-Lincoln on students’ endorsement of the New Ecological Paradigm (NEP) using a pre-course and post-course NEP scale survey. Analyzing paired responses (n = 40) through t-tests and z-scores, only four of 15 statements had statistically significant shifts observed for the entire sample. However, a targeted analysis of students initially possessing lower endorsement of the NEP—early deniers—revealed significant paradigm shifts post-course. While women initially showed stronger NEP endorsement, men demonstrated notable changes following the course towards endorsement of the NEP. Academic majors, whether …

Evaluation Of Heavy Metal Pollution, Water Quality, And The Effectiveness Of Remedial Sediment Dredging In The Lower Passaic River, New Jersey, Oluwafemi Soetan
Theses, Dissertations and Culminating Projects
Toxic metal pollution is a leading environmental concern for aquatic systems globally and remedial dredging has been widely employed to mitigate its harmful impacts. In terms of the short-term impacts of remedial dredging, mixed results are reported in several studies. Despite its immediate negative impacts including saturation of water with toxic metals, increased turbidity, and sediment resuspension, positive impacts can be recorded over a stabilization period of 6 – 24 months after dredging. Nevertheless, the sustainability of these recorded positive effects cannot be ascertained as some studies have reported long-term regression in remediated sites’ conditions.

Agricultural Economics and Agribusiness Faculty Publications and Presentations
Agricultural producers adopt management practices that positively and negatively affect the lives of non-producers in their communities. CRB has important environmental and human health implications, and local non-producers might have different perceptions and attitudes from agricultural producers about crop residue burning. In this paper, we use a multi-stakeholder approach to study the issue of crop residue burning (CRB). Survey data were collected from a sample of producers in Arkansas who burn crop residue and a sample of non-producers who resided in the same counties as the producers. Non-producers may not be willing to compensate producers at an amount that would …

Water Equity And Planning: Acid Mine Drainage In Deckers Creek Watershed, Brooke O. Waters, Lennon Jewell Auvil, Grace Dever
Undergraduate Scholarship
When mines close, they simply do not disappear. They cannot be buried or forgotten about. The implications of mining leave a lasting history and impact not only on our lands but on the people as well. Abandoned mine lands are areas of our community and environment that have been destroyed due to the extraction of coal and other minerals. Mining results in the destruction of landscapes, contamination of waterways, and the emission of harmful chemicals to our communities.
Acid Mine Drainage (AMD) is a resultant water pollutant that is derived from mining practices, active or abandoned. This pollutant forms from …
Developing More Useful Equity Measurements For Flood-Risk Management, Adam Pollack, Casey Helgeson, Carolyn Kousky, Klaus Keller
Developing More Useful Equity Measurements For Flood-Risk Management, Adam Pollack, Casey Helgeson, Carolyn Kousky, Klaus Keller
Dartmouth Scholarship
Decision-makers increasingly invoke equity to motivate, design, implement and evaluate strategies for managing flood risks. Unfortunately, there is little guidance on how analysts can develop measurements that support these tasks. Here we analyse how equity can be defined and measured by surveying 167 peer-reviewed publications that explicitly state an interest in equity in the context of flood-risk management. Our main result is a taxonomy that systematizes how equity has been, and can be, defined and measured in flood-risk research. The taxonomy embodies how equity is a pluralistic and unavoidably ethical concept. Despite this, we find that most quantitative studies fail …

Homemade Language, Conservative Fro-Yo, And Sci-Fi Sloths: How Speculative Migration Fiction Confronts The Ends Of Worlds By Challenging The Nation-State, Zoe R. Scheuerman
Homemade Language, Conservative Fro-Yo, And Sci-Fi Sloths: How Speculative Migration Fiction Confronts The Ends Of Worlds By Challenging The Nation-State, Zoe R. Scheuerman
English Honors Projects
This English literature thesis project explores an emerging, genre-defying body of fiction which I call “speculative migration fiction.” Speculative migration fiction imagines how ongoing global developments like climate change, technological development, and war may shape future migrations. Drawing on Benedict Anderson’s conception of national culture, Wendy Brown’s theory of the border, and Caroline Levine’s understanding of literary form, as well as close readings from Scattered All Over the Earth by Yōko Tawada, Exit West by Mohsin Hamid, and 2 A.M. in Little America by Ken Kalfus, I argue that transnational migrations move toward becoming postnational migrations as migrants evade border …

Community Conservation In Madagascar: Aligning Local Livelihoods And Biodiversity Protection, Jane Slentz-Kesler
Geography Honors Projects
The management of natural resources in developing countries is of utmost importance as both high levels of biodiversity and local livelihoods often hang in the balance. The debate in conservation spheres often centers on 'fortress' versus 'community-based' conservation approaches, one emphasizing nature preservation and the other emphasizing the needs and empowerment of local communities in resource management. This study evaluates the management approach of a rainforest in northeast Madagascar, asking: how effectively does the COMATSA Sud protected area management system both preserve critical forest cover and provide for the local community? This research employs a mixed-methods approach, using interviews and …
Ecosystem Response To Increasing Hurricane Disturbance: Comparing Nutrient Cycling Dynamics Associated With Early- And Late-Successional Tree Species In A Wet Tropical Forest, Miriam Kleit
Biology Honors Projects
Puerto Rico has seen changes in the frequency and severity of disturbances in recent years as hurricanes become more frequent and more intense under climate change. In ecosystems experiencing increasing disturbances, we expect that species composition will shift as early successional trees become more common. These changes to species composition and community ecology are likely to affect terrestrial nutrient cycling both directly and indirectly, and it is still not well understood how shifting community composition may alter ecosystem functioning. To address this gap, I measured carbon (C) and nitrogen (N) variables in soils, microbial biomass, roots, leaves, and soil greenhouse …
