Future Vision And Action Recommendations, Sondoss Elsawah, Melissa Haeffner, Anthony Jakeman

Environmental Science and Management Faculty Publications and Presentations

Let us imagine a future world where water management is more fully integrated and supported by the science of sociohydrology and related metadisciplines. This is a vision for the future where the social, cultural, environmental, and economic values of water are explicitly considered through the lens of the science–water policy interface. The ultimate value of research will be measured by how much it supports improvements in water resources and hazards management and, in particular, completes and enriches the science–water policy interface.

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.

Esg Performance Evolution In Retail: A Systematic Review And Meta-Analysis, Jiyeon Kim Ph.D., Wooyoung Yang

Faculty Publications

Environmental, social, and governance (ESG) practices have transformed from peripheral corporate social responsibility initiatives into core strategic imperatives in retail. Despite growing interest, the literature remains fragmented across disciplines and geographic contexts, with no comprehensive sector-specific analysis examining the evolution of ESG performance in retail contexts. Following the PRISMA 2020 guidelines, we conducted a systematic review and meta-analysis of 127 empirical studies published between 1988 and 2024 across major databases. Random-effects models assessed ESG-performance relationships, while stakeholder theory, the resource-based view, and Consumer Behavior frameworks explained the underlying mechanisms through temporal and subsectoral analysis. ESG practices demonstrate significant positive correlations …

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 …

This study aims to explore these interconnections by employing the Cellular Automata–Markov (CA–Markov) model to assess and predict LULC dynamics in Arkansas. Historical LULC datasets from 2001 to 2021, obtained from the National Land Cover Database, were simplified from 11 into 5 classes to facilitate analysis and effectively map transitions. The model was validated by predicting LULC for 2016 and 2021 and comparing the predictions with the real maps, achieving an overall accuracy of approximately 91.9%, using model validation metrics, including precision, …

Correcting Class Imbalance Through Synthetic Training Data And 3d Modeling For Carabid Pitfall Trap Sampling, Blair Mirka

Geography ETDs

Crowdsourced biodiversity data provide an accessible foundation for large-scale ecological monitoring, but class imbalance limits automated species identification, particularly for rare taxa. This research explores the use of synthetic training data generated from 3D models of carabid beetle museum specimens to improve detection and classification performance for underrepresented species in crowdsourced datasets. High-resolution 3D models were created to simulate variation in lighting, orientation, and background. These synthetic images were incorporated into convolutional neural network training datasets at varying synthetic-to-real ratios to assess their impact on classification accuracy. Models were evaluated using controlled pitfall-trap imagery to examine the influence of scene …

Marine Ornithology

From 2016 to 2019, we monitored the distribution, abundance, and age structure of California Brown Pelican Pelecanus occidentalis californicus at nearshore communal roosts along the U.S. West Coast. This effort used “snapshot” surveys during spring and fall, simultaneously engaging up to 111 “community science” participants, i.e., volunteers, on single dates. Volunteers surveyed up to 89 sites and found as many as 22,000 Brown Pelicans. We derived abundance and population structure indices from these data and sought relationships to annual breeding season metrics and large-scale oceanographic indices in the California Current System (CCS). The proportion of immature birds increased during the …

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. …

The current study investigates the relationship between noun classes and plant folk taxonomy in Chasu (G 22). The study focuses on two objectives: the first objective is to describe the plant folk taxonomy in Chasu and the second objective is to determine the relationship between noun classes and plant folk taxonomy in Chasu. Data were collected from rural villages in Same and Mwanga districts by using free listing, field interviews (jungle-walk-and-identify), and written texts containing Chasu plant names. The findings reveal that Chasu folk taxonomy reflects different ethnobotanical categories; including a unique beginner which is mmea/mimea ‘plant(s)’, and three life …

Exploiting Chloride Conservative Tendencies As Contaminant Surrogates In Groundwater Transport Modeling In A Typical Hydrogeological Environment Of Northern New Jersey, Toritseju Oyen, Duke Ophori

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

This study investigates the transport of chloride, a conservative tracer and surrogate for contaminants, in the fractured Brunswick aquifer of northern New Jersey using a dual-porosity MODFLOW-MT3DMS model. Focusing on the First Watchung Mountain region—a microcosm of northern New Jersey’s hydrogeological environment encompassing Montclair State University and adjoining communities, the numerical model simulates groundwater flow and solute transport in a hydrogeologically complex, urbanized setting. Results indicate that chloride migrates through the fractured aquifer via both local flow systems (e.g., Third River) and regional flow systems (Passaic River) within decades. Chloride concentrations exceeded the EPA’s 250 mg/L threshold much faster in …

Artificial Light At Night Can Worsen Competitive Outcomes Between Native And Invasive Grasses, Shannon M. Murphy, Kylee Grenis, Anna A. Sher

Biological Sciences: Faculty Scholarship

Artificial light at night (ALAN) is an important global disturbance that affects community dynamics, but how it affects species interactions, such as competition, is not well understood and needs investigation. In plant communities, some exotic-invasive plant species seem to be facilitated by ALAN, which may alter competitive outcomes with native plant communities and promote invasion. Despite these intriguing results, whether ALAN affects competitive outcomes between native and invasive species is understudied. Here we tested how ALAN affects competitive outcomes between two native prairie grasses and two grasses that are exotic-invasive in North America. We planted each native species with a …
