Quantifying Aboveground Biomass In A Tropical Forest Using A Lidar Waveform Weighted Allometric Model, Alejandro Rojas

Theses and Dissertations

Our knowledge of the distribution and amount of terrestrial above ground biomass (AGB) has increased using lidar technology. Recent advancements in satellite lidar has enabled global mapping of forest biomass and structure. However, there are large biases in satellite lidar estimates which impacts our understanding of carbon dynamics, particularly in tropical forests.

Ni-Meister et al. (2022) developed a lidar full waveform weighted height-based allometric model which produced very good results in temperate deciduous/conifer forest in the continental US. The purpose of this study was to evaluate this biomass model in an African tropical forest using the Land Vegetation and Ice …

Valuing Angling On Reservoirs Using Benefit Transfer, Richard T. Melstrom, Mark A. Kaemingk, Nicholas W. Cole, John C. Whitehead, Christopher J. Chizinski, Kevin L. Pope

Biology Faculty Publications

Economic assessments are rarely applied to inland recreational fisheries for management purposes, especially when compared to fish, habitat, and creel assessments, yet economic assessments can provide critical information for management decisions. We provide a brief overview of economic value, key terminology, and existing economic techniques to address these issues. Benefit transfer, a technique used to measure economic value when an original analysis is not practicable, is conducted by drawing on existing estimates of economic value in similar contexts. We describe an application of benefit transfer to measure the economic value of several recreational fisheries in Nebraska, USA. We examine two …

Heavy Metal Distribution Across Three Georgia Estuaries Using Coastal Sharks As Sentinel Species, Allyson Stiles

Master of Science in Integrative Biology Theses

Estuaries are transitional environments that play key roles in coastal ecosystem functioning by providing essential habitats to ecologically important plant and animal species. Estuaries are exposed to a number of anthropogenic impacts, including heavy metal contamination from human activities. However, few studies have examined heavy metal distribution within Georgia’s estuaries and how intact salt marsh ecosystems could play a role in filtering and sequestering contaminants, such as Mercury (Hg). This thesis examined blood total mercury (THg) concentrations of four coastal shark species and concentrations of five heavy metals (Hg, As, Cr, Cu, and Pb) within the water and sediments of …

Examining Emergency Citizen Response To The Covid-19 Pandemic: Emergent Groups Addressing Food Insecurity In Portland, Oregon, Aliza Ruth Tuttle

Dissertations and Theses

Emergency response agencies commonly focus on how hard infrastructure will interact with extreme climatic and geologic events: bridges during an earthquake and buildings following a tornado, for example. Peoples' actual experience of these extreme events vary, however, based on socially constructed consequences of natural hazard events and their interaction with a depleted or robust social safety net.

Previous research shows people living with depleted social safety nets and who experience a natural hazard event are likely to help where they see disaster. Individuals consistently form groups, called emergent groups, to organize their efforts. This research explored emergent groups that formed …

Genetic Freedom Of The Seas In The Age Of Extractivism: Marine Genetic Resources In Areas Beyond National Jurisdiction, Irus Braverman

Contributions to Books

Published as Chapter 4 in Laws of the Sea: Interdisciplinary Currents, Irus Braverman, ed.

Areas beyond national jurisdiction are the largest environment on earth and marine genetic resources are its new, and perhaps final, frontier. It is no wonder, then, that the scope and protection of marine genetic resources in this oceanic space have been hotly contested and that a new doctrine for ocean governance has been coined in this context: mare geneticum. This chapter examines different definitions of marine genetic resources debated in the ongoing treaty negotiations over areas beyond national jurisdiction (the BBNJ), the conflicting interests involved, and …

Amphibious Legal Geographies: Toward Land–Sea Regimes, Irus Braverman

Contributions to Books

Published as ine introduction to Laws of the Sea: Interdisciplinary Currents, Irus Braverman, ed.

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book discusses the juridical thinking that has enshrined the land/sea divide into contemporary governmental infrastructures, disciplinary traditions, and regulatory apparatuses, and charts the disastrous implications that such a legal fixation on the land/sea binary has wrought on human and other-than-human lifeworlds. As the collection proceeds, a second broad theme emerges, building on the first: when one rethinks the abstraction of law as played out on the ground, the …

Advances In Power System Operation And Optimization, You Lin

Electrical Engineering Theses and Dissertations

The modern power system has witnessed an increasing penetration of distributed energy resources and modern loads with variable frequency drives. The increasing complexity brings great challenges to modern power system operations. Significant efforts have been made to develop more accurate power system operation and optimization methods. The tradeoff between computation and the model structure makes the problem nontrivial to solve and analyze. Enabled by the wide deployment of PMUs and advanced machine learning algorithms, we improve the conventional power system operation and optimization techniques by improving the accuracy of power system measurements, implementing new power system modeling structures, and performing …

Optimization Of Drive Time And Competitiveness In Sports League Design, Zhuo Chen

Operations Research and Engineering Management Theses and Dissertations

Club sports, also known as recreational team sports, are prevalent in the metropolitan areas of United States nowadays. However, there is a key concern for organizers, which is how to reduce the time that players spend driving to and from matches while keeping league divisions competitive. We adopt a three-step approach to solve this problem. Initially, we analyze the drive time data between clubs’ locations to determine the geographic regions for the league. And then, clubs are assigned to divisions based on their rankings within in the league as well as their home facilities’ geographic regions. Finally, divisions are further …

Spatial And Temporal Characteristics Of California Commercial Fisheries From 2005 To 2019 And Potential Overlap With Offshore Wind Energy Development, Yi-Hui Wang, Ryan K. Walter, Crow White, Benjamin I. Ruttenberg

Physics

As climate change accelerates and fisheries management continues to evolve, California's commercial fisheries are changing. To improve the understanding of recent California fisheries dynamics, we compiled and analyzed commercial landings receipts to characterize temporal and spatial variation in landing and value of key fisheries groups within the exclusive economic zone across the state from 2005 to 2019. We found that California fisheries continue a shift first observed in the 1980s from higher‐biomass, lower‐value species, such as coastal pelagic species and market squid, toward lower‐biomass, higher‐value species, such as Dungeness crab Cancer magister and groundfish. Over the 15‐year time series analyzed, …

Building On Historical Chicana And Chicano Movement Pedagogies To Teach New Mexican Manita And Manito Epistemologies To Knowledge And Power Curators, Keith E. Sanchez

Chicana and Chicano Studies ETDs

ABSTRACT

Through the examination of historical place-based, culturally relevant, and responsive Chicana/o pedagogies, as exemplified in the formative 1969 El Plan de Santa Barbara, The Crusade for Justice, and la Academia de la Nueva Raza, the purpose of this project is to create a curricular sketch considering contemporary environmental and economic challenges facing Manita/o/Hispanic/Chicana/o student populations of New Mexico. If its ideals are to be generationally galvanized and sustained, every social movement must establish a semblance of Paideia, a space of grassroots educational initiative, where a marginalized community’s epistemologies are exhumed, reinvigorated, and passed to the next generation. This …

No. 03: Covid-19, The Hukou System And Migrant Food Security In Urban China, Fei Xu, Taiyang Zhong, Jonathan Crush

Migration and Food Security (MiFOOD) Network

The COVID-19 pandemic has issued significant challenges to food systems and the food security of urban and mobile populations. COVID-19 has had a disproportionate negative impact on household food security. In China, there have been no studies to date specifically focusing on the food security of migrants during the pandemic. This paper uses data from an online questionnaire survey of food security in Nanjing City, China, conducted in March 2020 to examine the different experiences of migrant and non-migrant households. The paper situates the research findings in the general literature on the migrant experience more generally during the pandemic and …

Afterword: Latcrit At Twenty-Five And Beyond – Organized Academic Activism And The Long Haul: Designing “Hybridized” Advocacy Projects For An Age Of Global Disruption, Systemic Injustice, And Bottom-Up Progress, Francisco Valdes, Steven Bender, Jennifer J. Hill

Denver Law Review

On the monumental occasion of the twenty-fifth anniversary celebration of LatCrit (Latina and Latino Critical Legal Theory, Inc.) as a still thriving and persevering community of critical scholars and activists, this Article offers some reflections on where we have been, where we are now, and where we might go next together as academics and organizers of long-term collective action. Against the current disruptions of a global pandemic, aggravated by planetary climate collapse, disinformation campaigns, and the organized top-down sabotage of U.S. democracy itself, our community responses going forward must be both more democratic and decentralized than ever, as well as …

Yoga As Property: A Century Of United States Yoga Copyrights, 1937–2021, Roopa Bala Singh

Denver Law Review

Public debate on yoga as property fixates on whether yoga should be owned, asking if yoga can be Indian property. Framed as such, the public discourse obscures a century-long, ravenous arc of yoga ownership in the United States, accumulated by whiteness, beginning in the early twentieth century. What do the stories of yoga in American law tell us and hide about property and intellectual property? In this critical intellectual property (IP) study, I present the first map of U.S. yoga copyrights grounded in quantitative data. The map reflects that yoga has been exponentially “propertized” by U.S. copyright law. My evidentiary …

Foreword: Mapping Critical Geographies In Virtual Space, Shelley Cavalieri, Saru M. Matambanadzo, Lua Kamal Yuille

Denver Law Review

In this Foreword to the LatCrit Symposium, the authors introduce the work of the 2021 LatCrit Biennial Meeting. They frame the movement as one of critical and liberatory theorizing in a time of retrenchment of opposition to the antisubordination project, highlighting the many strands of Critical Legal Studies that find home in the big tent of the LatCrit community. They introduce and contextualize within the broader critical theory literature four Articles written by members of the LatCrit community. Finally, they assert their own challenge to the movement, calling on critical legal scholars to question more seriously the meritocratic and productivist …

Defining Regenerative Business Through The Context Of Place: A Case Study West Michigan Businesses, Aislinn Teachout, Aislinn Teachout

Masters Theses

This study builds upon existing scholarly literature on regenerative design and regenerative sustainability by relating the framework to existing West Michigan businesses and their place-specific practices. Applying concepts from those more developed fields to business sustainability, this paper contributes to the still emerging field of regenerative business by proposing a comprehensive definition of regenerative business. The definition is then applied to three businesses in a case study format to highlight regenerative business practices. While none of the businesses highlighted claim to be regenerative, all have examples of practices that demonstrate regenerative action and enhance the West Michigan community.

By defining …

Pathways From Exposure To Community Violence To Bullying Victimization Among African American Adolescents In Chicago’S Southside, Dexter R. Voisin

Faculty Scholarship

The present study proposes and examines the pathways from exposure to community violence to bullying victimization through the influences of depression, exposure to peer delinquency, and drug use among 638 African American adolescents (aged 12–22) from low-resourced neighborhoods in Chicago’s Southside. The study found that African American adolescents who were exposed to community violence were likely at risk of bullying victimization, depression, exposure to peer delinquency, and drug use. Depression can heighten the risk of bullying victimization. These findings have implications for future research.

Acceptance Finds A Way: How To Teach And Use Evolution's Explanatory Power, Daniel George Ferguson

Theses and Dissertations

The theory of evolution is the central combing theory that brings together all the tenets of biology that bring about a solid understanding of life. It is also one of the most controversial scientific theories of all time and is widely rejected by about 40% of the general public in the United States. One of the biggest reasons for low evolution acceptance is the perceived conflict between evolution and religious beliefs. Educators and researchers have been working hard to improve how we teach evolution in the classroom; some methods, such as focusing on evolution knowledge, have shown to be mixed. …

Utilizing Real-Time Technology To Assess The Impact Of Home Environmental Exposures On Asthma Symptoms: Protocol For An Observational Pilot Study., Sharmilee Nyenhuis, Emily Cramer, Matthew Grande, Luz Huntington-Moskos, Kathryn Krueger, Olivia Bimbi, Barbara Polivka, Kamal Eldeirawi

Manuscripts, Articles, Book Chapters and Other Papers

Background: It is estimated that over 60% of adults with asthma have uncontrolled symptoms, representing a substantial health and economic impact. The effects of the home environment and exposure to volatile organic compounds (VOCs) and fine particulate matter (PM2.5) on adults with asthma remain unknown. In addition, methods currently used to assess the home environment do not capture real-time data on potentially modifiable environmental exposures or their effect on asthma symptoms.

Objective: The aims of this study are to (1) determine the feasibility and usability of ecological momentary assessment (EMA) to assess self-report residential environmental exposures and asthma symptoms, home …

Soils, Science And Community Action (Soilscan): A Citizen Science Tool To Empower Community-Led Land Management Change In East Africa, C Kelly, M Wynants, A Patrick, A Taylor, F Mkilema, M Nasseri, S Lewin, L Munishi, K Mtei, P Ndakidemi, W Blake

School of Geography, Earth and Environmental Sciences

Pastoralist communities worldwide face complex challenges regarding food and feed productivity. Primary production systems are under stress, nutritional choices are changing and the relationship between development and agriculture is undergoing profound transformation. Under increasing pressure from climate and land use change, East African agro-pastoral systems are approaching a tipping point in terms of land degradation. There is an urgent need for evidence-led sustainable land management interventions to reverse degradation of natural resources that support food and water security. A key barrier, however, is a lack of high spatial resolution soil health data wherein collecting such information for each individual community …
