Information Sources, Perceived Personal Experience, And Climate Change Beliefs, Sonny Rosenthal

Research Collection College of Integrative Studies

This study proposes and tests a model of serial mediation based on the norm activation model and value-belief-norm theory. It argues that beliefs about climate change are related to perceived personal experience, which is related to the use of different information sources. Structural equation modeling of survey data from 1084 adult residents of Singapore found mixed support for three hypotheses. Results showed that perceived personal experience of climate change was related to the use of traditional media (β = 0.20), social media (β = 0.16), and interpersonal sources (β = 0.13), but not institutional sources. Perceived personal experience of climate …

Where Gunshots Turn Fatal: A Geographic Examination Of The Spatial Patterning Of Gun Violence, David Hatten

Dissertations, Theses, and Capstone Projects

This dissertation contributes fundamental work to the examination of gun violence through an investigation of prevalence, trends, and likely place-based dynamics that explain the spatial patterning of gun violence in Kansas City, MO over a 5-year period (2015-2019). Specifically, this dissertation assesses 1) the degree to which separate shooting typologies (fatal and non-fatal) concentrate in micro-places, 2) whether they co-locate at micro-places, and 3) the likely community characteristics and place-based dynamics that explain these observed patterns. Importantly, the role of place-based dynamics related to the post-incident operational response to gun violence is tested (e.g., a street segment’s proximity to trauma …

Falling Forward: The Governance Of School Reform, Race, And The Contest For A Dignified Future In Newark, N.J., Claire Cahen

Dissertations, Theses, and Capstone Projects

Following the Great Recession, a two-pronged policy agenda of charter school creation and public school austerity was implemented in many impoverished, multiracial urban school districts in the U.S. The reforms have yet to meet durably effective resistance. The three articles that comprise this dissertation address questions about how school reforms, austerity, and privatization have been made governable, specifically in relation to the: preservation of local Black political machine power, creation of a labor market for charter school teachers, ongoing contestation attempts by public educators in inert unions. These questions correspond to theoretical debates about contemporary forms of racism and the …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Thermal variations in surface and atmosphere observed from multiple satellites prior to strong earthquakes have been widely reported ever since seismic thermal anomalies were discovered three decades ago. These thermal changes are related to stress accumulation caused by the tectonic activities in the final stage of earthquake preparation. In the present paper, we focused on the thermal changes associated with the 2021 Madoi M 7.3 earthquake in China and analyzed the temporal and spatial evolution of the Index of Microwave Radiation Anomaly (IMRA) and the Index of Longwave Radiation Anomaly (ILRA) based on 8-year microwave brightness temperature (MWBT) and 14-year …

Air Quality And Vehicular Emissions: Evaluating Vehicular Emission Contributions To And Distribution Of Ambient Particulate Matter Pollution With Low-Cost Sensors In Richmond, Virginia, Morgan Malstead

Environmental Studies Senior Seminar Projects

Hazardous air quality prematurely kills millions of people a year and exacerbates underlying health issues for millions more. Unsafe levels of particulate matter are typically associated with newly industrialized and developing countries, however, this is a misconception, especially when considering ambient air pollutants in densely packed urban areas. According to the Airbeam and Purple Air data collected on 07/15/2021, Richmond, Virginia has good air quality with the vast majority of values falling below the United States Environmental Protection Agency annual PM2.5 standard of 12 micrograms per cubic meter (μg/m3). Vehicular emissions may not account for a large percentage of PM2.5 …

A Possible Role For River Restoration Enhancing Biodiversity Through Interaction With Wildfire, Brittany E. Pugh, Megan Colley, Stephen J. Dugdale, Patrick Edwards, Rebecca Flitcroft, Andres Holz, Mathew Johnson, Michela Mariani, Mickey Means-Brous, Multiple Additional Authors

Geography Faculty Publications and Presentations

Background

Historically, wildfire regimes produced important landscape-scale disturbances in many regions globally. The “pyrodiversity begets biodiversity” hypothesis suggests that wildfires that generate temporally and spatially heterogeneous mosaics of wildfire severity and post-burn recovery enhance biodiversity at landscape scales. However, river management has often led to channel incision that disconnects rivers from their floodplains, desiccating floodplain habitats and depleting groundwater. In conjunction with predicted increases in frequency, intensity and extent of wildfires under climate change, this increases the likelihood of deep, uniform burns that reduce biodiversity.

Predicted synergy of river restoration and biodiversity increase

Our Streets: Increasing Equity In Active Transportation Planning Through Community Outreach, Jordan Hoy

Master's Projects and Capstones

ABSTRACT Significant research has demonstrated that active transportation infrastructure is essential for the growth and livability of San Francisco: it increases access to economic opportunities, promotes overall improved public health, encourages mobility without contributing to roadway congestion, prevents traffic injuries and fatalities, and supports the sustainability goals of the city. Despite the fact that communities of color will benefit the most from active transportation infrastructure development, historical disenfranchisement in tandem with a lack of diverse representation within public participation contributes to an inequitable distribution of walking and biking investments throughout the city of San Francisco. While research shows that Black …

Solving For Affordability In The San Francisco Housing Crisis: Is California’S Regional Housing Needs Allocation (Rhna) The Answer?, Matthew J. Mandich

Master's Projects and Capstones

Over the last two decades San Francisco has been suffering from a worsening housing shortage and affordability crisis, as housing production has lagged far behind job growth in the city and the region. As San Francisco’s housing market is especially supply constrained due to its unique geography, long-standing zoning laws, and convoluted permitting process, it is especially difficult to add the needed housing at an acceptable rate. Overall, this housing crisis has affected middle and lower income households the most as many have been forced to relocate due to rapidly increasing rents.

In an attempt to stimulate housing production state …

A Social-Ecological-Technological Systems Framework For Urban Ecosystem Services, Timon Mcphearson, Elizabeth M. Cook, Marta Berbés-Blázquez, Chingwen Cheng, Nancy B. Grimm, Erik Andersson, Olga Barbosa, David G. Chandler, Heejun Chang, Multiple Additional Authors

Geography Faculty Publications and Presentations

As rates of urbanization and climatic change soar, decision-makers are increasingly challenged to provide innovative solutions that simultaneously address climate change impacts and risks and inclusively ensure quality of life for urban residents. Cities have turned to nature-based solutions to help address these challenges. Nature-based solutions, through the provision of ecosystem services, can yield numerous benefits for people and address multiple challenges simultaneously. Yet, efforts to mainstream nature-based solutions are impaired by the complexity of the interacting social, ecological, and technological dimensions of urban systems. This complexity must be understood and managed to ensure ecosystem-service provisioning is effective, equitable, and …

Disorientations, Noah Greene-Lowe

MFA in Visual Art

The materials that make up the ordinary and mundane in the United States also reinforce and normalize a white spatial imaginary. Conventions of mapping, imaging of land and landscape, and elements of the built environment continue to orient us in a logic of space as property. In my sculptural work, I employ strategies of disorientation and creative repair, or reconstruction, to unsettle the spatial practices of whiteness and structures of power embedded in the mundane, the familiar, and the domestic. I consider the planned cohousing community where I grew up as an influence on my work, and my whiteness. By …

Structural Geology And Cenozoic Deformation: Western Northern Range, Trinidad, Abigail Faye Clark

Geology: Student Scholarship & Creative Works

The Northern Range, Trinidad underwent deformation due to oblique collision of Caribbean plate with northern South America, which was then followed by transform plate motion. Deformation began in the late Miocene when sedimentary protoliths were ductility deformed and metamorphosed to greenschist facies; this event and subsequent transform deformation drove exhumation of these rocks to the surface and created their high topography. This project provides constraints of the structural history of the western Northern Range where bedrock mapping and structural analyses are most complete. Initial geologic mapping of Northern Range, which continued from the 1950s,1960s, and 1990s, focused on attempting to …

Fragmented Landscapes: An Archaeology Of Transformations In The Pra River Basin, Southern Ghana, Sean Hamilton Reid

Dissertations - ALL

This doctoral archaeological research examines the Pra River Basin in southern Ghana through lenses of landscape, temporality, and transformation. Drawing on the Annales school and the writings of Tim Ingold, this study moves away from binary constructions of natural and cultural landscape features toward a more integrated view of the landscape's long human history. The primary temporal focus of this research is the past three millennia but evidence recovered of even more ancient eras is also examined. The artifacts and features documented while surveying this landscape allow us to glimpse pre-Atlantic (pre-1450 CE) settlement patterns, subsistence, and technology, as well …

Influence Of Altitude And Scan Angle On Uas-Lidar Ground Height Measurement Accuracy In Juncus Roemerianus Scheele (Black Needle Rush)-Dominated Marshes, Michael Amelunke

Master's Theses

Coastal marshes are influenced by complex interactions among environmental and human factors. Marsh plant communities exist across subtle elevation gradients which are highly influenced by the local tidal regime. To better understand these dynamic conditions, improved methodologies for acquiring accurate elevation values are a necessity in marsh research and management. However, overestimation of marsh elevation values obtained from remote sensing is common due to vegetation characteristics. The goal of this study was to address this problem by determining the optimum altitude and scan angle for Light Detection and Ranging (LiDAR) collection using an Unmanned Aerial System (UAS) within Juncus roemerianus …

To The Shores Of Tripoli: A Barbary Retrospective, Kathleen J. Brett

Senior Honors Projects, 2020-current

The First and Second Barbary Wars were incredibly influential in shaping the diplomatic and military tactics of the early United States. These wars were fought against the Barbary states of Tripoli, Tunis, Morocco, and Algiers, located on the Mediterranean coast of North Africa. The First Barbary War lasted between the years of 1801 to 1805. The First Barbary War began due to the United States’ desire to no longer pay tribute sums to the Barbary states, along with an increase in the number American merchantmen captured and enslaved by the Barbary states. Tripoli served as the primary aggressor in the …

Just Water Transitions At The End Of Sugar In Maui, Hawai'i, Chris Knudson, Alida Cantor, Kelly Kay

Geography Faculty Publications and Presentations

In December 2016, Hawai‘i saw its last sugar harvest on a 36,000-acre plantation in Maui. In the preceding decades, Native Hawaiians had struggled to regain their water rights from a failing sugar industry that had dewatered the island's streams for centuries. Now, with the end of sugar, Native Hawaiian and environmental groups are working to restore traditional practices and diversified agriculture—goals which hinge upon changing water management practices and rewatering Maui's streams. In this paper we combine frameworks from the water justice literature with a just transitions framework typically applied to energy landscapes in order to examine ‘just water transitions’ …

Using Lidar To Estimate Carbon Sequestration Of Evergreen Trees At Eastern Washington University (Ewu) Campus, Cheney, Washington, Kristy A. Snyder

2022 Symposium

EWU contains a variety of deciduous and evergreen trees across its campus, providing several benefits. However, no comprehensive record exists of the total number, location, species, or ages of these trees. This knowledge can inform facilities of proper care for individual trees and can be used to estimate carbon sequestration on campus. Traditional on-the-ground methods for assessing trees require tree cores or clinometers, making trees susceptible to pests or disease and leading to inaccurate results. Remote sensing using lidar data is a noninvasive, more precise method to measure tree height and subsequently assess tree age. This poster explores using point …

Delaware’S Climate Action Plan: Omission Of Source Attribution From Land Conversion Emissions, Elena A. Mikhailova, Lili Lin, Hamdi A. Zurqani, Zhenbang Hao, Christopher J. Post, Mark A. Schlautman, Gregory C. Post, George B. Shepard

Geography Faculty Publications and Presentations

Delaware’s (DE) Climate Action Plan lays out a pathway to reduce greenhouse gas (GHG) emissions by at least 26% by 2025 but does not consider soil-based GHG emissions from land conversions. Consequently, DE’s climate action plan fails to account for the contribution of emissions from ongoing land development economic activity to climate change. Source attribution (SA) is a special field within the science of climate change attribution, which can generate “documentary evidence” (e.g., GHG emissions inventory, etc.). The combination of remote sensing and soil information data analysis can identify the source attribution of GHG emissions from land conversions for DE. …

Family History, Cultural Custom, And Personal Preference: The Accents Of Food Access In Oxford, Mississippi, James Hirsch

Honors Theses

Contemporary food access literature in the social sciences centers on models of food decisions emphasizing income, prices, distance, and time. To challenge this analysis, this research conducts interviews with six residents of Oxford, Mississippi, focused on their food habits. These interviews have been summarized, and motivating factors have been extracted and compared back to the literature’s findings. The motivating factors found through the interviews include perceived differences in food quality, store opening/closing hours, partner/family preferences, family/cultural influences, and perceived risks from the COVID-19 pandemic. In contrast to the literature, spaciotemporal concerns were less dominating among participants than the above factors, …

Finding Resilience Through Research: Completing A Ph.D. While Parenting An Intellectually Disabled Adult “Child”, Lorraine M. Hutton

The Qualitative Report

Unlike the progression of most traditional-aged, college or university students, my non-traditional, academic trajectory as a parent-caregiver to an intellectually disabled (ID) adult has been fraught with barriers, disruption, and discouragement. Motivation to complete my doctorate rests on a commitment to disability issues, caregiver activism, and intellectual capacity-building of my self. Guided by the “evocative” autoethnographic methodology of Bochner and Ellis (2016), this “insider’s” narrative retrospective autoethnography will attempt to shed light on and evoke an understanding of a doctoral student caregiver’s context and experience in the academy. It encompasses embodiment, a geographically constrained sense of place, marginalization, and neoliberal …

The Spatial Associations Between Crime And Economy In Chicago 2015-2020, Hongtao Huang

Honors Capstones

The severity of the crime is often the most intuitive reflection of whether a region is safe and the top factor for the public when evaluating a region. Economist's list of the safest cities in seven major North American cities, Chicago was ranked at six, just above Dallas. Chicago scored the lowest in personal security, which is closely tied to the crime. Against the backdrop of higher unemployment and prices, this study is interested in how property-based crimes are related to the economic decline in Chicago geographically. The study used the heterogeneity analysis tool Geodetector to investigate the correlation between …

Interrogating Race And Place-Based Inequities In Hiv And Covid-19, Rohan Khazanchi

MD Honors Theses

Over the last four years, I have developed a research focus examining the intersections of race, place, and health. My M.D. Honors Thesis reflects a snapshot of these efforts. In this collection of brief research reports, I leverage area-based measures to investigate structural inequities in three contexts: the HIV epidemic in our hyperlocal community, the early stages of the COVID-19 pandemic, and clinical trials for novel COVID-19 therapeutics. I apply novel social epidemiologic tools to measure and explore disparate outcomes. And, in reflecting upon my findings, I discuss concrete implications for clinicians, researchers, and policymakers alike.

From The Abacus To Big Data: The Evolution Of Data-Driven Planning In The U.S. And Where The Field Will Be Headed, Keuntae Kim

Journal of Comparative Urban Law and Policy

The nature of planning involves a set of decision-making processes to fulfill people’s needs and expectations of where they live, work, and play. Dealing with the nature of planning—complexity, uncertainty, and disagreement—requires specific tools to explore various aspects of the built environment as a whole. Various types of data have been extracted, transformed, and loaded to describe the past and current conditions of the built environment, and planners have developed and applied data-driven planning tools to explore the knowns and unknowns of the urban futures and transform them into a set of actions based on the goals with consensus. This …
