Purchasing Choices That Reduce Climate Change: An Exploratory Factor Analysis, Yuhan Bi, Kimberly Barchard

Spectra Undergraduate Research Journal

Household consumption is a primary source of green-house gas emissions. Individuals can substantially reduce their climate impact by making sustainable purchasing choices, such as choosing products that are made locally and have less packaging, buying used, repairing items rather than replacing them, supporting libraries and bike-share programs, encouraging others to buy less, and donating to charity in someone’s name rather than buying gifts. The Climate Change Action Inventory measures the frequency of 77 daily behaviors, including 14 items regarding Climate-Friendly Purchasing Choices. The purpose of this research was to determine if purchasing choices could be divided into meaningful factors. We …

Influential Individuals Can Promote Prosocial Practices In Heterogeneous Societies: A Mathematical And Agent-Based Model, Stefani A. Crabtree, Colin D. Wren, Avinash Dixit, Simon A. Levin

Environment and Society Faculty Publications

In this paper, we examine how different governance types impact prosocial behaviors in a heterogenous society. We construct a general theoretical framework to examine a game-theoretic model to assess the ease of achieving a cooperative outcome. We then build a dynamic agent-based model to examine three distinct governance types in a heterogenous population: monitoring one's neighbors, despotic leadership, and influencing one's neighbors to adapt strategies that lead to better fitness. In our research, we find that while despotic leadership may lead towards high prosociality and high returns it does not exceed the effects of a local individual who can exert …

The Effect Of Chemical Coagulant Dosages On The Removal Of Turbidity From Wastewater, Estabraq Ali Hameed, Rodhan Abdullah Salih, Ali Mohammed Saleh, Hussein M. Issa, Mahmod A. Abdulqader

Wildlife Conservation: The Importance Of Individual Personality Traits And Sentience, Karen A. Owens, Gosia Bryja, Marc Bekoff

Animal Sentience

Individual differences in personality types within the same species have been studied much less than differences between species and populations. Personality differences are related to risk-taking and exploration, which in turn correlate with individuals' daily responses, decisions, and fitness. Bold and shy personality types can have different advantages and disadvantages under different social or environmental pressures. Analyzing personality differences has helped clarify how elk habituate to a well-populated area and how management strategies can be adapted to them. For wolves newly repatriated to Colorado, individual personality factors are likely to prove important for adapting to their new homes as well …

A Geochemical Mechanism For >10 M Apparent Downward Offsets Of Magnetic Reversals Inferred From Comparison Of Two Scotia Sea Drill Sites, Brendan T. Reilly, Lisa Tauxe, Stefanie A. Brachfeld, Bridget Kenlee, Marcus Gutjahr, Andrew W. Dale, Iván Hernández-Almeida, Sidney Hemming, Ian Bailey, Xufeng Zheng, Daven Cheu, Reece Taglienti, Michael E. Weber, Maureen E. Raymo, Trevor Williams

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

We document an apparent downward displacement of the Matuyama-Brunhes magnetic reversal by ∼20 m at Scotia Sea International Ocean Discovery Program Site U1538 (Pirie Basin) by comparison with the well-defined paleomagnetic record at nearby Site U1537 (Dove Basin). Detailed stratigraphic correlation between the two sites is possible due to similar lithologic variations. However, the two sites have distinctly different porewater geochemistry. Notably, Site U1538 indicates a greater demand for electron acceptors to oxidize organic carbon and Fe²⁺ enrichment below the depth of SO4²⁻ depletion. Magnetic parameters indicate enrichment of an authigenic magnetic mineral with strong remanence properties around …

The southeastern United States Coastal Plain ecosystem contains baldcypress (Taxodium distichum) swamps and grass-dominated marshes. These ecosystems also occurred on the exposed continental shelf during lower sea levels but are rarely preserved due to the mechanically erosive nature of transgression and regression. Two presently marine sites on the northeastern Gulf of Mexico's continental shelf contain well-preserved woody terrestrial sediments that were the subject of previous studies. This study continues the investigation using geochemical (δ13C, δ15N, δ34S) and palynological characteristics of these formerly terrestrial sediments to determine if swamps and/or marshes existed at the time of deposition. The first site is …

Deconstructing Disability In Malawi: A Multi-Perspective Qualitative Study On Understandings, Policy Development, And Policy Implementation, Johanna Lee

Capstone Collection

Disability models serve as frameworks to conceptualize understandings of disabilities, influencing the creation of policies and programs. The United Nations, through the Convention on the Rights of Persons with Disabilities (CRPD), has established international standards influenced by disability models from the Global North. Despite Malawi’s efforts to adopt the CRPD through numerous measures, people with disabilities still face challenges in accessing healthcare. The effectiveness of current policies in the health sector remains unclear. Therefore, it is crucial to consider local perspectives on disabilities, as well as differences in culture and livelihoods. This research employs thematic analysis to assess the perceptions …

Modelling Postfire Recovery Of Snow Albedo And Forest Structure To Understand Drivers Of Decades Of Reduced Snow Water Storage And Advanced Snowmelt Timing, A. Surunis, K. E. Gleason

Environmental Science and Management Faculty Publications and Presentations

Forest fires darken snow albedo and degrade forest structure, ultimately reducing peak snow–water storage, and advancing snowmelt timing for up to 15 years following fire. To date, no volumetric estimates of watershed-scale postfire effects on snow–water storage and snowmelt timing have been quantified over decades of postfire recovery. Using postfire parameterizations in a spatially-distributed snow mass and energy balance model, SnowModel, we estimated postfire recovery of forest fire effects on snow–water equivalent (SWE) and snowmelt timing over decades following fire. Using this model, we quantified volumetric recovery of forest fire effects on snow hydrology across a chronosequence of eight sub-alpine …

Nitrous oxide (N2O) is a greenhouse gas and stratospheric ozone-depleting substance with large and growing anthropogenic emissions. Previous studies identified the influx of N2O-depleted air from the stratosphere to partly cause the seasonality in tropospheric N2O (aN2O), but other contributions remain unclear. Here, we combine surface fluxes from eight land and four ocean models from phase 2 of the Nitrogen/N2O Model Intercomparison Project with tropospheric transport modeling to simulate aN2O at eight remote air sampling sites for modern and pre-industrial periods. Models show general agreement on the seasonal phasing of zonal-average N2O fluxes for most sites, but seasonal peak-to-peak amplitudes …

Stories Elicit Feelings Of Kinship And Inspire Pro-Environmental Behavior, Ellen Shaw

School of Education and Leadership Student Capstone Projects

Humans pass down stories to transmit ways of knowing and ways of interacting within their culture. For Indigenous humans, stories give outsiders insight into a deeply intertwined connection with the environment. As a woman of European descent teaching Environmental Education classes, my lack of awareness inspired the question, How can a story lead to adolescents developing a kinship with the more-than-human elements of a place and lead to pro-environmental behavior grounded in reciprocity? The literature review focused on elevating Indigenous authors such as; Robin Wall Kimmerer, Gregory Cajete, Jessica Hernadez, Albert Wiggan, Masanobu Fukuoka. Traditional Ecological Knowledge is the current …

Integrating Environmental Education Into The 4th-Grade Classroom, Brandi Mckenna

School of Education and Leadership Student Capstone Projects

The growing awareness of the effects of climate change on our planet and the need for solutions that slow, stop, or potentially reverse these effects have led to the desire to increase environmental education in our youth. Research shows that building environmental literacy and stewardship helps create citizens with pro-environmental behaviors. Since the Tbilisi Declaration in 1977, there has been significant growth in environmental education programs in non-traditional education settings.

Ocean Literacy: Understanding The Importance Of Sharks In Marine Ecosystems, Nicole Mueller Januário

School of Education and Leadership Student Capstone Projects

The ocean covers about 71% of our planet’s surface and provides us with food and marine resources. It regulates global climate and weather patterns, and acts as a climate change carbon sink yet remains largely unprotected. A restorative human-ocean relationship is urgently needed to combat the negative impacts of humanity and climate change and support marine biodiversity. Sharks, one of the oldest fish species and apex predators, play a crucial role in maintaining a balanced marine ecosystem and healthy ocean. However, sharks are threatened by climate change and illegal, unregulated, unreported fishing and finning. A radical behavior change is also …
