Addressing Critiques Refines Global Estimates Of Reforestation Potential For Climate Change Mitigation, Kurt A. Fesenmeyer, Erin E. Poor, Drew E. Terasaki Hart, Joseph W. Veldman, Forrest Fleischman, Pooja Choksi, Sally Archibald, Mohammed Armani, Matthew E. Fagan, Evan C. Fricke, César Terrer, Natalia Hasler, Christopher A. Williams, Peter W. Ellis, Susan Cook-Patton

Geography

Reforestation is a prominent climate change mitigation strategy, but available global maps of reforestation potential are widely criticized and highly variable, which limits their ability to provide robust estimates of both the locations and total area of opportunity. Here we develop global maps that address common critiques, build on a review of 89 reforestation maps created at multiple scales, and present eight reforestation scenarios with varying objectives, including providing ecosystem services, minimizing social conflicts, and delivering government policies. Across scenarios, we find up to 195 Mha (million hectares) are available (2225 TgCO2e (teragrams of carbon dioxide equivalent) per year total …

We coupled a drone-based environmental DNA (eDNA) canopy swabbing approach with portable quantitative PCR (qPCR) to detect Plasmodium DNA in situ during a 24-h field exercise in the Amazon rainforest. Drone-lowered sterile swabs into the canopy, which were then extracted and subjected to a multiplex pan-Plasmodium assay targeting five human-infecting Plasmodium species (limit of detection 0.2 parasites μL−1). Of 12 samples (10 canopy swabs, 2 field blanks; 13 total runs including repeats), one canopy swab amplified in duplicate (Ct = 28.7 and 29.23), …

Charity Begins With Zoning Reforms, Mark D. Bjelland

University Faculty Publications and Creative Works

When my family moved to Michigan over a decade ago, we were looking for something more than a three-bedroom house in our price range. We wanted a place of beauty, refreshment, and welcome for our children and guests. As newcomers to the state, we took the location seriously. Our previous house lost value due to its small-town setting, so we worried about future property values. As an urban geographer, I mapped changes in demographics and housing prices and created bike and bus travel-time maps from work and schools.

Local Problems, Global Solutions? Making It Rain In Hong Kong C. 1890-1930, Fiona Williamson

Research Collection College of Integrative Studies

The late nineteenth to early twentieth century saw a small but dedicated rise in experimental rainmaking. The possibility that humanity might one day be able to control the weather – especially to alleviate drought – was very attractive to governments and private investors. The late nineteenth century was an era of scientific optimism and a number of rainmaking experiments across the world had brought the potential for weather control out of the realms of discourse and literature and further into tangible near-future science. There has been a small but thorough historiographical literature on this subject, focusing largely on American, British, …

Light Or Acid? Suppressing Water Deactivation In Saf Production Via Phenyl-Mediated Charge Transfer In Wox/Zrox-Functionalised Pmos, Vannia C. Dos Santos-Durndell, Mark A. Isaacs, Jinesh C. Manayil, Lee J. Durndell

School of Geography, Earth and Environmental Sciences

The aviation sector contributes ∼2.5 % of global energy-related CO2 emissions, driving demand for sustainable aviation fuel production (SAF) from biomass. However, water, whether intrinsic or produced in situ, often drives on-stream catalyst deactivation, reducing efficiency and creating barriers to process scale-up. Here, we present an exciting new approach using WOx/ZrOx-functionalised periodic mesoporous organosilica (PMO) photocatalysts that exhibit exceptional stability and performance under aqueous conditions. The incorporation of bis(triethoxysilyl)benzene (BTSB) into the PMO framework not only enhances surface hydrophobicity and acidity but also strategically positions organic π-conjugated phenyl groups next to WOx/ZrOx active sites. These phenyl moieties act as conductive …

Many highly hazardous, caldera-forming explosive eruptions occur in extensional tectonic regimes, but the role of lithospheric rifting in modulating caldera volcanism remains enigmatic. IODP Expedition 398 deep-drilled the volcano-sedimentary infills of submarine half-grabens around Santorini caldera on the continental South Aegean Volcanic Arc. Here we use the volcanic tephra archives to produce a high-resolution eruptive chronostratigraphy for Santorini, to ground-truth seismic stratigraphy, and to extract an integrated timeline of volcano-tectonic couplings. The rift basins contain several submarine volcaniclastic megabeds from the caldera-forming eruptions of Santorini and one from the Kos caldera. The thickest megabed succession is < 250,000 yrs old and lies on a seismic reflection onlap surface that records a phase of rapid rifting. Sedimentation lagged behind subsidence during this rifting phase, creating bathymetric troughs. Integrating submarine core-seismic and onland datasets, we propose that rifting may have driven the transition of Santorini from a prolonged state of effusive and minor explosive activity (∼550 – 250 ka) typical of arc stratovolcanoes to one of repeated caldera-forming eruptions (<250 ka). Rapid rifting may have amplified the normal internal dynamics of the magmatic system in three ways, driving the volcano into a sustained, highly explosive state: (1) an increase in the supply of mantle-derived basalt, (2) enhanced shearing, permeability, and melt percolation in the transcrustal magmatic system, and (3) the development of horizontally extensive magma reservoirs. Broadly simultaneous transitions into caldera-forming activity of the widely separated Santorini and Kos Volcanoes suggest that the two magmatic systems are linked by plate-scale lithospheric stresses.

Navigating Ai-Nature Frictions: Autonomous Vehicle Testing And Nature-Based Constraints, Prerona Das, Orlando Woods, Lily Kong

Research Collection College of Integrative Studies

In cities, the application of Artificial Intelligence (AI) is being directed towards transforming different aspects of urban life. These applications take material form in urban spaces, with autonomous vehicles (AVs) providing a prominent example. AI systems rely on large volumes of data on their surroundings to refine the algorithms and enhance the accuracy of prediction for operational efficiency and safety. However, such algorithmic learning and execution can present challenges when dealing with the unpredictable, complex, and dynamic aspects of urban spaces. Nature is a paradigmatic example of such unpredictability, because natural phenomena usually defy consistent patterns and precise data-based modelling. …

The Pluralistic Natural Capital Values Of A Tropical City, Adrienne Gret-Regamey, Et Al.

Chasing The Dream And Buying The Promise In A Conceptual Framework For Consumer Decision-Making, Casey H. Prentice

Communication & Theatre Arts Theses

The American dream is a concept that is echoed across our society, and while the data show Americans do not overwhelmingly believe in the dream, marketers continue to pair it and the issue of economic prosperity in their agendas. Through a novel framework that overlaps a deeply studied mass communication theory with a decision-making framework used in marketing, this paper demonstrates a new lens to understand how marketers identify strategies and tactics, build agendas, and make sales by touting the American dream. As separate entities, decision-making models and agenda setting theory are powerful, but together can create an environment that …

When Nonbinary Becomes Binary: Exploring Transnormativity Experiences Of Gender Diverse Individuals, Yusuf Barburoğlu

Counseling & Human Services Theses & Dissertations

Transnormativity is a within-group framework that positions trans and nonbinary (TNB) individuals in a hierarchy of legitimacy based on adherence to binary gender norms (Johnson, 2016). Nonbinary individuals, who comprise 38% of U.S. transgender adults, face unique challenges, including systemic invalidation, misgendering, and erasure both within and outside LGBTQIA+ communities (James et al., 2024; Matsuno et al., 2024). These experiences intersect with internalized stigma and rejection expectations, contributing to mental health disparities (Budge et al., 2014; Lefevor et al., 2019). This study explores how nonbinary individuals navigate, resist, and embody transnormative pressures, using Sarah Ahmed’s Queer Phenomenology and Interpretative Phenomenological …

A Systematic Review Of Corporate Ethics Program Training Strategies To Improve Ethical Workplace Cultures, Robin Raye Altice

Educational Leadership & Workforce Development Theses & Dissertations

The demand for corporations to practice more ethically responsible conduct and decision making is growing with every news report of another corporate scandal, lawsuit, fine, or high-visibility C-suite firing. To develop an ethical workplace culture, organizations should implement a comprehensive ethics program that fosters and encourages ethical decision making, especially among current and future leaders. However, there is little research and few guidelines for how ethics program administrators should design corporate ethics training to effectively practice and master the skill of ethical decision-making in efforts to continually grow a more ethical work environment.

Violence As An Ecology: Women Making Safety In Khayelitsha, Melissa J. Miller-Felton

Graduate Program in International Studies Theses & Dissertations

This dissertation asks how women in Khayelitsha make safety in a place where danger has become ordinary and where the afterlives of colonialism and apartheid still determine who waits, who walks, and who arrives home. What began as a study of risk and protection grew into an inquiry about time, dignity, and responsibility. I call the framework that emerged an ecology of violence—a way of seeing how harm gathers across generations and infrastructures, and how care, exhaustion, and survival intertwine within it.

In this ecology, violence is not a single act but a confluence of registers—slow, structural, colonial, and …

Reading The Romance Reader: Booktok, Algorithmic Subjugation, And The Fight For Cultural Legitimacy, Emily Maranto Hill

Communication & Theatre Arts Theses

This thesis examines the transformation of romance reader identity through the lens of BookTok, investigating how digital platforms grant cultural legitimacy while simultaneously subjugating community practices to algorithmic control. Romance readers historically developed emotional labor practices, counter-public formation strategies, and fan-driven meaning-making to resist decades of cultural marginalization. Through analysis of TikTok's platform attributes, user behaviors, and the viral Tillie Cole controversy, this study traces how BookTok converts these resistant practices into behavioral data optimized for engagement rather than authentic discourse. The research employs theoretical frameworks including Janice Radway's ethnographic analysis, Shoshana Zuboff's surveillance capitalism, Nick Srnicek's platform capitalism, and …

Pilot-C: Physics-Informed Low-Distortion Optimal Trajectory Compression, Kefei Wu, Baihua Zheng, Weiwei Sun

Research Collection School Of Computing and Information Systems

Location-aware devices continuously generate massive volumes of trajectory data, creating demand for efficient compression. Line simplification is a common solution but typically assumes 2D trajectories and ignores time synchronization and motion continuity. We propose PILOT-C, a novel trajectory compression framework that integrates frequency-domain physics modeling with error-bounded optimization. Unlike existing line simplification methods, PILOT-C supports trajectories in arbitrary dimensions, including 3D, by compressing each spatial axis independently. Evaluated on four real-world datasets, PILOT-C achieves superior performance across multiple dimensions. In terms of compression ratio, PILOT-C outperforms CISED-W, the current state-of-the-art SED-based line simplification algorithm, by an average of 19.2%. For …
