Senay, Mackenzie Friedrichs, Koong Yi, Joshua B. Fisher, Lixin Wang, Kosana Suvočarev, Arman Ahmadi, Housen Chu, Stephen Good, Kanishka Mallick, Justine Missik, Jacob A. Nelson, David E. Reed, Tianxin Wang, Xiangming Xiao

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Remote sensing-derived evapotranspiration (RSET) products capture the spatiotemporal variations of evapotranspiration (ET) from field to basin scales with unprecedented details. However, their accuracy varies across RSET estimation methods and diverse hydroclimate regions. While ET modeling efforts to account for biophysical processes and controlling parameters have made good progress in recent years, a parallel approach of integrating in-situ ET with RSET could reduce biases in RSET products. Basin water balance ET (WBET) and flux tower ET are widely applied to evaluate RSET accuracy, yet such ET measurements are rarely used for RSET bias corrections, especially for large area applications. To address …

Towards An Indigenous Climate Epistemology: Bringing The Newa Literary Tradition Of The Swasthani Vrata Katha In Conversation With The Festival Tradition Of The Macchindra Nath Jatra, Shangrila Joshi Dr.

Critical Humanities

This paper brings into conversation two Newa cultural traditions to articulate notions of climate adaptation, resilience, and mitigation, to illustrate how ways of knowing, ways of being, and ways of governing are inherently linked. These articulations offer a framework for developing what the author calls an Indigenous Climate Epistemology. The two cultural traditions reviewed include: a 17^th century Newa literary tradition that advocates for keeping oil in the ground, and that instructs ordinary people to engage in ritual acts seemingly designed to develop personal and community resilience; and a 1700 year old annual community festival designed to avert catastrophes …

Los Mapas Gráficos Multi-Dato De Los Viajes Científicos De Humboldt Como Precedente De Los Modernos Sistemas Socio-Ecológicos, Norberto Muñiz Martínez

Homage to Alexander von Humboldt: Travels to and from Spain Throughout the Centuries / Homenaje a Alexander von Humboldt: Viajes hacia y desde España de todos los siglos

Este artículo analiza el papel visionario de Alexander von Humboldt como científico geógrafo que sentó las bases de la integración de los análisis geográfico-ecológicos y los humano-sociales. Humboldt fue precursor de la interdisciplinaridad científica, integrando la observación científico-empírica basada en la recogida de datos, con un subjetivismo compatible con el sentimiento hacia la naturaleza y los seres vivos. Humboldt aunó metodológicamente ese enfoque dual en análisis gráficos que captaban las complejidades derivadas de los sistemas complejos y emergentes, donde el todo en su conjunto es más que la suma de partes fragmentadas. Su visión combinaba análisis de ámbito local y …

Building Belonging Infrastructure In Cities: Arts/Culture-Based Critical Participatory Action Research And Youth, Kimberly Rae Nightingale

Dissertations and Theses

Belonging is a critical human need. Urban planning's history of bureaucratic expertise continues to champion the powerful, resulting in structures and procedures that still separate and damage city communities. This research challenges the current hegemony of urban planning that centers geography--the container of land--in its practice. Instead, centering the belonging of people to each other is the essential quality of healthy urban planning. A people-centered urban planning practice where the community's people are the experts and decision-makers of their own cities--and belonging is the primary objective--is long overdue.

Arts/culture-based critical participatory action research (PAR)--where the research questions, design, data collection, …

Use Of High-Throughput Phenomics With And Without Fungicide As A Wheat Breeding Tool, Gerardo Ivan Rivera Collazo

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Wheat (Triticum aestivum) is an important food staple for many countries around the world and current consumption and production data demonstrate a production deficit. Breeders are challenged to help close this gap in production by selecting better cultivars with improved yields. Several methods aim to accelerate the breeding process to reduce the time required for releasing an elite variety. One of the main breeding bottlenecks is the lack of fast and reliable phenotypic data acquisition that could dissect physiological and morphological plant data. High-throughput remote sensing could have the potential to reduce this bottleneck by streamlining data acquisition, …

Politics And Institutional Change: The Water Commission Act Of 1913, Mark Kanazawa

Department of Economics Working Paper Series

Economists have long argued that increasing resource scarcity can lead to more clearly defined individual property rights, but the precise mechanism whereby this occurs remains unclear to this day. This paper documents the role of politics in shaping the creation of individual property rights within the context of appropriative water law in early 20th century California, finding evidence of both party ideology and interest group influence in establishing a new system for administering appropriative water rights.

Relative Hazard Losses Along The Atlantic And Gulf Coasts, Erin Kemp

Reluctant Transitions: Place And Post-Extraction Politics In Southeastern Ohio, Jenna Lynn Haver

Theses and Dissertations

Based on a summer of ethnographic research in a subsection of Appalachian Ohio colloquially referred to as “The Valley,” this research challenges three narratives of this place that formulate a harmful Appalachian imaginary. The first narrative of industrycontrolled coal heritage is complicated by the way local people negotiate control over their own stories of coal and its existence outside of industry domain. The second narrative characterizes this as a space of extraction which is in tension with different social relations to varying types of energy – especially the discontinuity of the coal to fracking shift. The third narrative centers of …

Combining Remote Sensing And Field Sampling To Assess Microphytobenthos Distribution In The North Inlet Estuary, South Carolina, Joseph Carmine Mcguinn

These findings demonstrate the value of remote sensing for …

Between Florida And The World: Young People And The Politics Of Citizenship, Jessica Flach

Theses and Dissertations

This thesis critically examines how American high school students experience and make sense of global citizenship within the context of a commercial educational tour. Drawing on a case study of students from a Title I public high school in Florida, the research interrogates the narratives of civic transformation promoted by educational travel companies and explores how these narratives intersect with students’ lived realities. Combining ethnographic methods, interviews, and critical discourse analysis, the study reveals that global citizenship is not meaningfully realized through such travel experiences; rather, it is fragmented, depoliticized, and often disconnected from the civic education students receive in …
