Adapting To Aridity: Crop Production Trends Among Smallholder Farmers In Iramba District, Tanzania, Nashokigwa Shalua, Digna Wolfram Mlengule, Johnstone M. Andrea

Tanzanian Economic Review

Increasing crop production amid recurrent droughts remains a critical challenge for smallholder farmers in the semi-arid Iramba District; however, empirical evidence on crop production remains scarce. This paper analysed trends in crop production in Iramba District from 1995 to 2024. Mixed methods were used, and data were collected through structured interviews, focus group discussions, field observations, in-depth interviews and document reviews. Quantitative data were analysed using descriptive statistics while qualitative data were thematically analysed. The results indicate that 84.2% (n=95) of the households showed an increase in crop yields despite concurrent severe drought. Sunflower, maize, bulrush millet, and sorghum were …

Artificial Intelligence As A Catalyst For Systemic Sport Ecology, Ugo Arbieu, Laís Carneiro, Sonia Tieo, Franck Courchamp

Journal of Applied Sport Management

Artificial intelligence (AI) is reshaping both sport management and environmental science, yet these developments have largely evolved in parallel. AI can serve not merely as a technical tool but also as a catalyst for systemic sport ecology, a field that integrates sport, digital innovation and environmental sustainability. Advances in discriminative, generative and agentic AI enable the synthesis of complex ecological and sport-related data, improving monitoring, forecasting, resource efficiency, policy design, and decision-making across scales. In doing so, AI offers a pathway beyond fragmented sustainability interventions and can support holistic approaches to the interconnected crises of climate change, pollution, and biodiversity …

Research Advances On Foreign Portfolio Investments: A Bibliometric And Thematic Analysis, Ritu Sapra, Dixit Yadav, Kamal Upreti, Nishant Kumar, Rituraj Jain, Akhilesh Tiwari

Markets, Globalization & Development Review

Foreign portfolio investments have been at the center of research in the finance, economics, and international business domains since the early 1990s when developing economies started to relax their capital account and allowed the entry of foreign investments. Over the years, various macroeconomic (country-specific and global), firm-specific, and quality factors have been studied as determinants in relation to these flows, Still, there is no consensus regarding which factor influences more than the others. This paper uses bibliometric analysis to understand the existing literature to build a solid conceptual base in this research topic. For this study, bibliometric data of 731 …

Building Bridges: Industrial Trade Unions In A Changing Climate, Nicole Möller

Dissertations - ALL

This dissertation examines how German industrial trade unions and workers in the automobile and coal industries navigate the profound challenges of the green transition. Workers’ experiences are situated within a broader political-economic context shaped partly by market-led decarbonization efforts, welfare retrenchment/austerity, erosion of progressive institutions in society, and global competition, as well as a global restructuring of value accumulation. The analysis critically engages with unions’ current responses to a market-led transition and their implications for labor’s future. The dissertation develops its argument across three empirical chapters. Chapter 2 investigates workplace-level changes in coal mining and automobile production, analyzing how workers …

Multi-Satellite Image Matching And Deep Learning Segmentation For Detection Of Daytime Sea Fog Using Gk2a Ami And Gk2b Goci-Ii, Jonggu Kang, Hiroyuki Miyazaki, Seung Hee Kim, Menas Kafatos, Daesun Kim, Jinsoo Kim, Yangwon Lee

Institute for ECHO Articles and Research

Traditionally, sea fog detection technologies have relied primarily on in situ observations. However, point-based observations suffer from limitations in extensive monitoring in marine environments due to the scarcity of observation stations and the limited nature of measurement data. Satellites effectively address these issues by covering vast areas and operating across multiple spectral channels, enabling precise detection and monitoring of sea fog. Despite the increasing adoption of deep learning in this field, achieving further improvements in accuracy and reliability necessitates the simultaneous use of multiple satellite datasets rather than relying on a single source. Therefore, this study aims to achieve higher …

Gis Librarians' Involvement In Critical Information Literacy Instruction, Melissa Chomintra, Pete E. Pascuzzi

Libraries Faculty and Staff Scholarship and Research

Critical information literacy (CIL) is a theory and practice that considers the sociopolitical dimensions of information and knowledge production. As the field of geospatial information evolves, equipping librarians with the skills to critically engage with geospatial information becomes integral to facilitating informed research, promoting spatial literacy, and strengthening the accessibility of geospatial data for their user communities. To understand geospatial data librarians’ current involvement in CIL, librarians were surveyed to examine if they incorporate CIL into their instruction, how they incorporate CIL into their instruction, and what are the benefits and challenges of doing so. The survey gathered both quantitative …

Marooned: A Western Frontier Dismal Swamp Narrative, Professor Meya E. Hargett

The Scholarship Without Borders Journal

Marooned: A Western Frontier Dismal Swamp Narrative centers the erased figure of Samuel Mars, a lost Black station master whose movements through the Great Dismal Swamp have been excluded from dominant Underground Railroad cartographies. Here, the term “Marooned” refers not to abandonment, but to the maroon geographies of Black and Indigenous resistance encoded in land, lineage, and fugitive infrastructure.

Guided by Diasporic Maroon Memory Theory, Lineage as Method, and the Maroon Geographies Framework, this research reconstructs Mars’s trajectory through oral testimony, spatial patterning, and ancestral land memory. Rather than casting the Dismal Swamp merely as a site of refuge, this …

Spatial Conversations: Opportunities To Share Geographic Knowledge, L. Jesse Rouse, Barbara L. Maclennan, Susan J. Bergeron, H. Franklin Lafone

Anthropology and Geography

For more than twenty years geographers have taken advantage of “new media” to share information, make connections, and expand the “spatial conversation.” As blogs opened the door for informal self-publishing and communicating about narrow, focused topic areas, geographers began to use emerging media platforms to present ideas to a broader audience, more quickly and interactively, as new data and technologies became available. Audio podcasts and videos broadened the platforms for dissemination and provide a greater level of immersion through digital media. Between the open publishing and subscription opportunities, and interaction provided through comments and social media engagement, a dialectic was …

Towards Spatial Inversion Of Aerial Gamma-Ray Survey Data For Measurement Of Naturally Occurring Radioactivity, Daniel A. Haber

UNLV Theses, Dissertations, Professional Papers, and Capstones

Aerial gamma-ray surveying (AGRS) is used in geologic and environmental contexts to provide data on the surface spatial distribution of naturally occurring radioactive material (NORM) or other gamma-ray-emitting isotopes. The standard data reduction workflow for AGRS data involves a process whereby pointwise gamma-ray spectral data are denoised, corrected for numerous sources of background radiation and aircraft height, and are finally converted to physical values by empirical conversion factors. The reduced pointwise data are then typically spatially interpolated to form a continuous surface map.

This dissertation introduces and explores a novel spatial inversion method for reduced AGRS data that considers aircraft …

The Chemistry Of Color: A Comparative Analysis Of Natural And Synthetic Dyes In Textile Application, Caitlyn Pinaga Cpht

Honors Program Theses and Research Projects

We identified blue rings in samples from the Uinta and Wasatch Mountains, matching previous samples in the Greater Yellowstone Ecosystem. These blue rings are helpful in building comprehension of past climatic data.

Book Review: Ecologies Of Inequity. How Disaster Response Reconstitutes Race And Class Inequality, Abel Traslaviña-Arias

Critical Disaster Studies

In Ecologies of Inequity: How Disaster Response Reconstitutes Race and Class Inequality, Sancha Doxilly Medwinter gathered diverse stories about how various migrant communities had to overcome not only disaster but also the overlapping networks established by those who were supposed to support them in 2012 in New York City. Medwinter portrays this contested post-disaster landscape through a thorough data recording of 120 individuals affiliated with various groups: racialized migrants or locals, tenants or property owners, local or external helpers, and those from wealthy or impoverished backgrounds. Ecologies of Inequity refer to the spatialized networks of organizational and interpersonal relations …

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 …

Real-Time Malaria Detection In The Amazon Rainforest Via Drone-Collected Edna And Portable Qpcr, Yin Cheong Aden Ip, Luca Montemartini, Jia Jin Marc Chang, Andrea Desiderato, Nicolás D. Franco-Sierra, Christian Geckeler, Mailyn Adriana Gonzalez Herrera, Michele Gregorini, Meret Jucker, Steffen Kirchgeorg, Martina Lüthi, Elvira Mächler, Frederik Bendix Thostrup, Guglielmo Murari, Marina Mura, Paola Pulido-Santacruz, Florencia Sangermano, Tobias Schindler, Claus Melvad, Stefano Mintchev, Kristy Deiner

Geography

Zoonotic malaria risk at human-wildlife-environment interfaces requires surveillance that integrates signals from reservoirs, vectors and the environment. 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), …

Israeli Hasbara And The Nba’S Palestine Exception: The Impossibility Of Capitalist “Social Justice”, Chen Chen, Anthony J. Weems, Roc Rochon, Daniel Sailofsky

Sport Management Collection

Sport is a notable site for the Israeli state in its hasbara (public diplomacy, or “explaining”) effort that seeks to normalize the conditions of ethnic cleansing, illegal settlement, and apartheid practices in historic and occupied Palestine. Against the backdrop of the genocide in Gaza and the lack of international sport sanctions against Israeli teams, this paper maps several hasbara activities/attempts featuring the National Basketball Association (NBA) in the last decade. This is a worthwhile case, not least because of the NBA’s self-branding as a socially “progressive” league composed of a primarily Black/African American athletic workforce. Two major observations are made: …

Linking Climate And Demography To Predict Population Dynamics And Persistence Under Global Change., Jennifer L. Williams, Amy L. Angert, Aldo Compagnoni, Ali Campbell, Megan L. Demarche, Margaret E K Evans, Joshua C. Fowler, Amy M. Iler, Jenna A. Loesberg, Allison M. Louthan, Scott W. Nordstrom, Multiple Additional Authors

Publications, Reports and Presentations

Predicting the effects of climate change on plant and animal populations is an urgent challenge for understanding the fate of biodiversity under global change. At the surface, quantifying how climate drives the vital rates that underlie population dynamics appears simple, yet many decisions are required to connect climate to demographic data. Competing approaches have emerged in the literature with little consensus around best practices. Here we provide a practical guide for how to best link vital rates to climate for the purposes of inference and projection of population dynamics. We first describe the sources of demographic and climate data underlying …
