Interdependent Infrastructure As Linked Social, Ecological, And Technological Systems (Setss) To Address Lock-In And Enhance Resilience, Samuel A. Markolf, Mikhail Chester, Daniel A. Eisenberg, David Iwaniec, Cliff I. Davidson, Rae Zimmerman, Thaddeus R. Miller, Benjamin Ruddell, Heejun Chang

Geography Faculty Publications and Presentations

Traditional infrastructure adaptation to extreme weather events (and now climate change) has typically been techno-centric and heavily grounded in robustness—the capacity to prevent or minimize disruptions via a risk-based approach that emphasizes control, armoring, and strengthening (e.g., raising the height of levees). However, climate and nonclimate challenges facing infrastructure are not purely technological. Ecological and social systems also warrant consideration to manage issues of overconfidence, inflexibility, interdependence, and resource utilization—among others. As a result, techno-centric adaptation strategies can result in unwanted tradeoffs, unintended consequences, and underaddressed vulnerabilities. Techno-centric strategies that lock-in today’s infrastructure systems to vulnerable future design, management, and …

The Heat Is On! Perspectives And Practices Regarding Extreme Heat Risk, Emily D. Esplin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Remembering negative experiences with extreme heat may promote future protective actions and provide insight to improve heat risk awareness and communication practices. This two-part thesis found 1) that experiencing heat-related health symptoms predicted what Americans would do to protect themselves and others during subsequent heat waves; and 2) that Utah professionals regard heat-related experience as an important factor in how they responded to extreme heat events.

In the first study, a US national survey showed that personal experience with heat-related health symptoms was related to the tendency to say that one engaged in different protective behaviors, while other factors like …

The Unequal City: The Mass Criminalization Of The Urban Poor., Elizabeth Michele Jones

Electronic Theses and Dissertations

Exploring and understanding the widespread use of arrests and incarceration in urban neighborhoods of concentrated poverty is the subject of this dissertation. The research addresses gaps in theoretical debates about the causes of mass criminalization that position the phenomenon as the result of either neoliberalism or racism. In addition, the dissertation explores the impact of mass criminalization on urban citizenship. Urban citizenship is a theoretical frame that considers the substance of the economic, social, political, and mobility dimensions of city life. The research methodology is a case study of two impoverished neighborhoods in the city of Louisville, Kentucky that incorporates …

India’S Unbalanced Urban Growth: An Appraisal Of Trends And Policies, Purva Sharma

Journal of Global Initiatives: Policy, Pedagogy, Perspective

India is considered as a low-level urbanized country. However, the country has experienced a sharp increase in the number of towns and peri-urban areas during the last decade. Despite India’s efforts in planned development, the urban sector has generally remained unplanned and chaotic. It appears that policy interventions have not been able to achieve the desired goals and needs of the urban sector fully. This paper examines the urban policy measures taken since independence and highlights the inadequacies and dilemmas in the urban context of India. This analysis shows how metropolitan areas are spreading outwards due to shifts in population …

The Evacuation Of Phnom Penh During The Cambodian Genocide: Applying Spatial Video Geonarratives To The Study Of Genocide, James A. Tyner, Andrew Curtis, Sokvisal Kimsroy, Chhunly Chhay

Genocide Studies and Prevention: An International Journal

On April 17, 1975 Khmer Rouge soldiers began the forcible evacuation of Phnom Penh, Cambodia’s capital city. The evacuation has been the subject of considerable debate surrounding the Cambodian genocide and remains a topic of prime importance toward the understanding of Khmer Rouge policy and practice. In this field note, we present a geographically-informed account of the evacuation in order to provide a more fine-grained analysis of Khmer Rouge practice. More specifically, employing spatial video geonarratives, we provide a systematic investigation of the evacuation, as retraced by six evacuees. In so doing we contribute also to the emergent use of …

Keeping Pace With Relative Sea Level Rise: Marsh Platform Monitoring Shows Minimal Sediment Deficit Along The Louisiana Coast, Kelly Marie Sanks

Graduate Theses and Dissertations

Recent reports estimate that the marshes of the Mississippi Delta receive just 30% of the sediment necessary to sustain current land area1. An extensive monitoring campaign by the USGS and LCPRA provides direct measurements of sediment accumulation, subsidence rates, and deposit characteristics along the coast over the past 10 years2, allowing us to directly evaluate this sediment balance. By interpolating bulk density, organic fraction, and vertical accretion rates from 273 sites, a direct measurement of organic and inorganic sediment accumulation can be made. Results show that a total of 82 MT/year of sediment is delivered to the coast. Using a …

Decadal Land Surface Phenology And Water Quality In The Headwaters Illinois River Watershed, Justin Ray Rollans

Graduate Theses and Dissertations

Over 25 percent of the world’s population either lives on or obtains water from karst aquifers. The complex interactions between subsurface karst geologic features, the constant motion of the plant life cycle, and significant water resource demand all suggest the need to better define those interactions. The relationship of historical land surface phenology and water quality in karst topography were investigated in the Headwaters Illinois River watershed in Northwest Arkansas (NWA). This area represents high vulnerability to surface water and groundwater contamination, with both natural and anthropogenic processes such as over application of broil litter for enhanced cattle browse, affecting …

Spatio-Temporal Reconstruction Of Remote Sensing Observations, Kamrul Khan

Graduate Theses and Dissertations

The USDA Forest Service aims to use satellite imagery for monitoring and predicting changes in forest conditions over time within the country. We specifically focus on a 230, 400 hectares region in north-central Wisconsin between 2003 - 2012. The auxiliary data collected from the satellite imagery of this region are relatively dense in space and time and can be used to efficiently predict how the forest condition changed over that decade. However, these records have a significant proportion of missing values due to weather conditions and system failures. To fill in these missing values, we build spaciotemporal models based on …

Constructing A Data-Based Mortality Profile For Avian Tower Kills At Telecommunication Towers In Illinois, Rachel Dipietro

Theses and Dissertations

During spring and fall seasons, Neotropical migratory passerines travel nocturnally across the Western Hemisphere between their wintering and breeding grounds, often encountering man-made threats. One hazard that has gained considerable publicity in recent decades is the communication tower. While there have been many tower kill studies recorded, there has been no attempt at predicting the risk of towers based on their different attributes (e.g., height, type of light, landscape placement) spatially on a regional scale. The objective of this study was to create seasonal mortality profile maps in GIS for Illinois, based on tower attributes combined with key factors such …

Mathematics, Physics, and Computer Science Faculty Articles and Research

This study estimates the impact of dust aerosols on surface solar radiation and solar energy in Egypt based on Earth Observation (EO) related techniques. For this purpose, we exploited the synergy of monthly mean and daily post processed satellite remote sensing observations from theMODerate resolution Imaging Spectroradiometer (MODIS), radiative transfer model (RTM) simulations utilizing machine learning, in conjunction with 1-day forecasts from the Copernicus Atmosphere Monitoring Service (CAMS). As cloudy conditions in this region are rare, aerosols in particular dust, are the most common sources of solar irradiance attenuation, causing performance issues in the photovoltaic (PV) and concentrated solar power …

Efficient Sampling For Ecosystem Service Supply Assessment At A Landscape Scale, Franfisco Javier Ancin-Murguzer, Lorena Muñoz, Christopher Monz, Per Fauchald, Vera Helene Hausner

Environment and Society Faculty Publications

Decision makers and stakeholders need high-quality data to manage ecosystem services (ES) efficiently. Landscape-level data on ES that are of sufficient quality to identify spatial tradeoffs, co-occurrence and hotspots of ES are costly to collect, and it is therefore important to increase the efficiency of sampling of primary data. We demonstrate how ES could be assessed more efficiently through image-based point intercept method and determine the tradeoff between the number of sample points (pins) used per image and the robustness of the measurements. We performed a permutation study to assess the reliability implications of reducing the number of pins per …

A Comparison Of Machine Learning Techniques For Taxonomic Classification Of Teeth From The Family Bovidae, Gregory J. Matthews, Juliet K. Brophy, Maxwell Luetkemeier, Hongie Gu, George K. Thiruvathukal

Faculty Publications

This study explores the performance of machine learning algorithms on the classification of fossil teeth in the Family Bovidae. Isolated bovid teeth are typically the most common fossils found in southern Africa and they often constitute the basis for paleoenvironmental reconstructions. Taxonomic identification of fossil bovid teeth, however, is often imprecise and subjective. Using modern teeth with known taxons, machine learning algorithms can be trained to classify fossils. Previous work by Brophy et al. [Quantitative morphological analysis of bovid teeth and implications for paleoenvironmental reconstruction of plovers lake, Gauteng Province, South Africa, J. Archaeol. Sci. 41 (2014), pp. 376–388] uses …

Using Redundant Primer Sets To Detect Multiple Native Alaskan Fish Species From Environmental Dna, Damian Menning, Trey Simmons, Sandra Talbot

United States National Park Service: Publications

Accurate and timely data regarding freshwater fish communities is important for informed decision-making by local, state, tribal, and federal land and resource managers; however, conducting traditional gear-based fish surveys can be an expensive and time-consuming process, particularly in remote areas, like those that characterize much of Alaska. To help address this challenge, we developed and tested five multi-species environmental DNA (eDNA) primer sets for the simultaneous detection of up to 37 target fish species in a single sample. Using these primer sets can reduce the cost and time needed to perform future studies of fish communities. Our results comparing multiple …

School of Technology Publications

This paper provides an overview of oil spill scenarios and the remote sensing methods used for detection and mapping the spills. It also discusses the different kinds of thermal sensors used in oil spills detection. As UAS is becoming an important player in the oil and gas industry for the low operating costs involved, this research involved working with a cheap thermal airborne sensor mounted on DJI Phantom 4 system. Data were collected in two scenarios, first scenario is collecting data in Michigan’s Upper Peninsula at a petroleum company location and the second scenario was an indoor experiment simulating an …

Assessing The Cooling Effects Of Urban Vegetation On Urban Heat Mitigation In Selected U.S. Cities, Qiuyan Yu

USF Tampa Graduate Theses and Dissertations

Urban Heat Island (UHI) is a growing problem worldwide. Mitigation of UHI is necessary for cities to adapt to climate change and enhance sustainable development at a city scale. Cooling cities with urban vegetation management is a sustainable solution for urban heat mitigation. Urban vegetation influences urban microclimate through the shading effect, surface roughness, and evapotranspiration. The differences in horizontal and vertical structures of urban vegetation determine the shading effect, surface roughness, and evapotranspiration. Enhancing the cooling effect of urban vegetation requires a comprehensive understanding of how vegetation structure affects UHI. The effects of horizontal structure on land surface temperature …

Mapping Soil Alkalinity And Salinity In Northern Songnen Plain, China With The Hj-1 Hyperspectral Imager Data And Partial Least Squares Regression, Lin Bai, Cuizhen Wang, Shuying Zang, Changshan Wu, Jinming Luo, Yuexiang Wu

Faculty Publications

In arid and semi-arid regions, identifying and monitoring of soil alkalinity and salinity are in urgently need for preventing land degradation and maintaining ecological balances. In this study, physicochemical, statistical, and spectral analysis revealed that potential of hydrogen (pH) and electrical conductivity (EC) characterized the saline-alkali soils and were sensitive to the visible and near infrared (VIS-NIR) wavelengths. On the basis of soil pH, EC, and spectral data, the partial least squares regression (PLSR) models for estimating soil alkalinity and salinity were constructed. The R² values for soil pH and EC models were 0.77 and 0.48, and the root …

Evaluation Of Spatial Generalization Characteristics Of A Robust Classifier As Applied To Coral Reef Habitats In Remote Islands Of The Pacific Ocean, Justin J. Gapper, Hesham El-Askary, Erik J. Linstead, Thomas Piechota

Mathematics, Physics, and Computer Science Faculty Articles and Research

This study was an evaluation of the spectral signature generalization properties of coral across four remote Pacific Ocean reefs. The sites under consideration have not been the subject of previous studies for coral classification using remote sensing data. Previous research regarding using remote sensing to identify reefs has been limited to in-situ assessment, with some researchers also performing temporal analysis of a selected area of interest. This study expanded the previous in-situ analyses by evaluating the ability of a basic predictor, Linear Discriminant Analysis (LDA), trained on Depth Invariant Indices calculated from the spectral signature of coral in one location …

The Spatialization Of Peace Amidst Militarization And Development In Buenaventura, Colombia., Maria Del Pilar File-Muriel

Shared Knowledge Conference

Innovative community driven spatial practices are integral to sustaining long lasting peace amidst post-peace-accords times and the continued structural genocide of Afro-Colombians and indigenous communities in Buenaventura, Colombia. This paper illuminates the case of multiple transformative spaces --the Humanitarian Space Puente Nayero and the Comunal Port Punta Icaco in the city of Buenaventura, the rural interethnic humanitarian and biodiversity space of La Esperanza and the Paro Cívico struggle in the district of Buenaventura-- as examples of the creative power of citizens and of the transformative production of spaces of peace that resist local and global violent development and urbanization processes. …

La Gota Que Colma La Caguama: How A Brewery Development Sparked Public Participation In Water Decisions, Anthony J. Meluso

Shared Knowledge Conference

Broad and diverse participation of actors is well recognized as a prerequisite for effective and equitable water management. However, scholarship in development and social movement literature in Latin America demonstrates that patterns of participation are shifting to more diverse strategies with non-traditional alliances. This project explores how an internationally owned brewery development sparked renewed participation from various urban and rural groups in the Mexicali Valley. I argue that widespread resistance from different groups was underpinned by neoliberal development tensions that have diminished local agency, but the strong symbolic nature of water, beer and politics provided the catalyst for a social …

Textures Of Transition: Understanding Memorial Spaces In Medellin, Colombia, Hayley Pedrick

Shared Knowledge Conference

The past decade has welcomed a surge in the creation of memory and human rights museums with existing scholarship linking concepts of transitional justice and the rush to memorialize. The role of symbolic reparation in transitional justice through memorials in Latin America, in particular, is increasingly prominent at both local and international scales, ranging from recommendations outlined by the Inter-American court system to the state-funded construction of memory sites in rural communities. Colombia, home to the longest ongoing civil conflict in the Americas and currently in transition towards peace, presents unique approaches to symbolic reparation. Apart from land restitution and …

Elevation And Azimuth-Aided Channel Estimation Scheme For Airborne Hyperspectral Data Transmission, Vahid Vahidi, Ebrahim Saberinia

Electrical & Computer Engineering Faculty Research

A channel-estimation (CE) scheme is proposed to estimate the complex amplitude, Doppler shift, angle-of-departure, and angle-of-arrival of the channel taps for sparse and doubly selective channels for hyperspectral image transmission from unmanned aircraft vehicles (UAVs) to ground stations. The proposed method is dubbed as compressed-sensing joint parameter estimation (CS-JPE) and finds the channel parameters matrix by employing a compressed-sensing (CS)-based method. Afterward, a modified version of the joint parameter estimation (JPE) is proposed as CS-JPE and is dubbed as M-CS-JPE, which employs the elevation-azimuth angles of the line-of-sight channel tap to estimate the channel parameters with higher accuracy and lower …

Bhutan Landscape Anomaly: Possible Effect On Himalayan Economy (In View Of Optimal Description Of Elevation Profiles), Thach N. Nguyen, Laxman Bokati, Aaron A. Velasco, Vladik Kreinovich

Departmental Technical Reports (CS)

Economies of countries located in seismic zones are strongly effected by this seismicity. If we underestimate the seismic activity, then a reasonably routine earthquake can severely damage the existing structures and thus, lead to huge economic losses. On the other hand, if we overestimate the seismic activity, we waste a lot of resources on unnecessarily fortifying all the buildings -- and this too harms the economies. From this viewpoint, it is desirable to have estimations of regional seismic activities which are as accurate as possible. Current predictions are mostly based on the standard geophysical understanding of earthquakes as being largely …

Finding Ft. Smith And Ft. Star In Smithland, Ky, Austin Valentine, Austin Valentine Jr.

Student Scholarship & Creative Works

Through the utilization of Light Detection and Ranging data, one can compile 3-dimensional models that can be used to spot anomalies of historical interest. These anomalies, if recognizable by the trained eye, can then be used to geo-reference historic maps to gain a better understanding of historic sites as well as to reveal possible areas of interests or unknown features.

By using a 3-dimensional model compiled by LiDAR data, I was able to geo-reference a December 13^th, 1861 map of the Civil War defenses for the town of Smithland, Kentucky. Through this process, I have been able to …

No. 16: Cheap Industrial Food And The Urban Margins, Tony Weis, Marylynn Steckley, Bruce Frayne

Hungry Cities Partnership

From the middle of the 20th century onwards, the productivity gains associated with high-input, high-yield monocultures and livestock operations have become increasingly central to global food security and to dynamics of urbanization across the global south. On one hand, competition has deflated prices and helped undermine the viability of small farm livelihoods in many places. On the other hand, rising flows of cheap food have effectively subsidized urban migration in impoverished urban and peri-urban settings. But this cheapness is highly deceptive, as it hinges on the failure to account for an array of biological and physical costs – which can …

No. 17: Revisiting Africa's Supermarket Revolution, Jonathan Crush, Ndeyapo Nickanor, Lawrence N. Kazembe, Jeremy Wagner

Hungry Cities Partnership

Africa is urbanizing at an unprecedented rate and food systems are undergoing rapid transformation. This transformation is being driven in part by a global supermarket revolution. However, the idea of an inexorable supermarket revolution on the continent has recently been contested. This paper examines the role of supermarkets in Namibia’s capital city Windhoek to test the applicability of the model. The paper is based on (a) a review of the literature on South African supermarket expansion; (b) a survey of the food purchasing behaviour of a representative sample of 875 households in Windhoek; and (c) a comprehensive product inventory of …

No.03: Devising Urban Food Security Policy For African Cities, James Sgro

Hungry Cities Partnership

■ Informal food services are one of the few options for financially disadvantaged families. Food access policy needs to be created in partnership with informal economy actors to ensure that those who rely on informal systems are not ignored.

■ As household size increases, the likelihood of food insecurity grows exponentially. Adequate social protection programs are required to support household dependants including children and the aged and improve food security.

■ Secondary school completion is a specific milestone that significantly increases one’s food security outlook. Free primary and secondary school policies could return dividends in terms of nation-wide food security, …
