What The Walls Say: Finding Meaning And Value In Tel Aviv’S Street Art, Rachel R. Bird Jan 2018

What The Walls Say: Finding Meaning And Value In Tel Aviv’S Street Art, Rachel R. Bird

Honors Theses

This thesis explores street art in Tel Aviv, Israel through anthropological concepts of value. By defining street art as an interstitial practice—one that exists between permeable, socially defined boundaries and is characterized differently by different power structures—I attempt to define some of the different regimes of value that apply to street art. Using the emerging market of “street art tours” as a fieldwork site, I look at how street art is presented and re-presented to both tourists and locals. By situating my research in a historical and geographic context, I hope to understand the ways different value schema, from economic …

Motives For Patenting A Map Projection: Did Fame Trump Fortune?, Mark Monmonier Jan 2018

Motives For Patenting A Map Projection: Did Fame Trump Fortune?, Mark Monmonier

Geography and the Environment - All Scholarship

John Parr Snyder claimed that patenting a map projection was largely pointless because essentially similar transformations are readily available in the public domain. Map projection patents are rare, many patentees did not attempt to develop their patents, and none who did seems to have made much money. An explanation for their decision to patent lies in recognition that the patent system and peer-reviewed scientific journals are parallel literatures, either of which can satisfy an innovator’s need for attention, as suggested by achievement motivation theory. Moreover, no single factor can account for the invention of a map projection that was patented: …


Superpixel-Based Hyperspectral Unmixing With Regional Segmentation, Mohammed Qassim Alkhatib Jan 2018

Superpixel-Based Hyperspectral Unmixing With Regional Segmentation, Mohammed Qassim Alkhatib

Open Access Theses & Dissertations

Unsupervised unmixing analysis aims to extract the basic materials, also known as, endmembers, and their fractions (or abundances) from a hyperspectral image. In this work, a new unsupervised unmixing approach based on Low Dimensional representation with regional analysis is developed. A low dimensional image representation is obtained using superpixel segmentation where each superpixel is represented by its mean spectra. Regional analysis is then performed using the quadtree segmentation based on the Shannon entropy. Endmembers are extracted from each region and combined using clustering into endmember classes. The proposed approach is tested and validated using the HyDICE Urban, ROSIS Pavia, and …


Geometry, Timing, And Kinematics Of Neogene Extensional And Transtensional Structures Of Southern Death Valley: Implications For Regional Reconstructions And A Corrective Method For Rigid Body Rotations, Zachariah Fleming Jan 2018

Geometry, Timing, And Kinematics Of Neogene Extensional And Transtensional Structures Of Southern Death Valley: Implications For Regional Reconstructions And A Corrective Method For Rigid Body Rotations, Zachariah Fleming

Open Access Theses & Dissertations

Chapter 1:Advancements in computing capabilities over the last decade have allowed for the routine creation of Structure from Motion-Multiview Stereo (SfM-MVS) terrain models that can serve as base for high resolution geologic mapping. Outcrops models developed from these systems are high-resolution, photo-realistic 3D base providing unprecedented capability for geometric analysis. Yet, before this technology becomes a mainstay of field geology, the potential errors associated with it must be well understood. Here, we compare orientation measurements from multi-point analyses on the SfM-MVS point clouds to those taken in the field with the objective of resolving the geometry of complex folds within …


Reducing Uncertainties In Applying Remotely Sensed Land Use And Land Cover Maps In Land-Atmosphere Interaction: Identifying Change In Space And Time, Yaqian He, Timothy A. Warner, Brenden E. Mcneil, Eungul Lee Jan 2018

Reducing Uncertainties In Applying Remotely Sensed Land Use And Land Cover Maps In Land-Atmosphere Interaction: Identifying Change In Space And Time, Yaqian He, Timothy A. Warner, Brenden E. Mcneil, Eungul Lee

Faculty & Staff Scholarship

Land use and land cover (LULC) data are a central component of most land-atmosphere interaction studies, but there are two common and highly problematic scale mismatches between LULC and climate data. First, in the spatial domain, researchers rarely consider the impact of scaling up fine-scale LULC data to match coarse-scale climate datasets. Second, in the temporal domain, climate data typically have sub-daily, daily, monthly, or annual resolution, but LULC datasets often have much coarser (e.g., decadal) resolution. We first explored the effect of three spatial scaling methods on correlations among LULC data and a land surface climatic variable, latent heat …

The Gundlach Collection : A Study Of Projectile Points From The Albeni Falls Reservoir, Jeffrey Cortlund Johnson

EWU Masters Thesis Collection

A formerly private collection of projectile points belonging to the Kalispel Tribe of Indians Cultural Resources Program provides stylistic, temporal, and geographic information for sites in the Albeni Falls Reservoir, Idaho. Specifically, there are 462 artifacts from 24 sites based on information derived from the collector’s and tribal archaeologist’s notes. Depositional information is unknown and artifacts are as surface finds. Analyses performed in this study include the morphological and technological dimensions of style, geographic and temporal distribution of artifacts by site, comparative results of obsidian x-ray fluorescence, and high-resolution photography. The results demonstrate the collection as a pragmatic dataset yielding …


Modeling And Mapping Location-Dependent Human Appearance, Zachary Bessinger Jan 2018

Modeling And Mapping Location-Dependent Human Appearance, Zachary Bessinger

Theses and Dissertations--Computer Science

Human appearance is highly variable and depends on individual preferences, such as fashion, facial expression, and makeup. These preferences depend on many factors including a person's sense of style, what they are doing, and the weather. These factors, in turn, are dependent upon geographic location and time. In our work, we build computational models to learn the relationship between human appearance, geographic location, and time. The primary contributions are a framework for collecting and processing geotagged imagery of people, a large dataset collected by our framework, and several generative and discriminative models that use our dataset to learn the relationship …


“I Thought I Found Home”: Locating The Hidden And Symbolic Spaces Of African American Lesbian Belonging, Aretina Rochelle Hamilton Jan 2018

“I Thought I Found Home”: Locating The Hidden And Symbolic Spaces Of African American Lesbian Belonging, Aretina Rochelle Hamilton

Theses and Dissertations--Geography

This dissertation investigates the place-making practices of African American lesbians in Atlanta, Georgia, from 1990 to 2010. For this project, I ask how African American lesbians claim space to examine how race, sexuality, and class shape their place-making practices. The study is situated in the city before and following the 1996 Olympic Games, which was a period of rapid social, economic, and political growth.

The primary question posed in this study is as follows: How do African American lesbians claim space in Atlanta? This dissertation posits three arguments. First, African American queer spaces are transitory, reflecting the shrinking boundaries of …


“Beyond Sisterhood There Is Still Racism, Colonialism And Imperialism!” Negotiating Gender, Ethnicity And Power In Madagascar Mangrove Conservation, Manon Lefèvre Jan 2018

“Beyond Sisterhood There Is Still Racism, Colonialism And Imperialism!” Negotiating Gender, Ethnicity And Power In Madagascar Mangrove Conservation, Manon Lefèvre

Theses and Dissertations--Geography

Understanding women’s experiences of mangrove forest conservation in the Global South is important because mangrove forests are a crucial defense against climate change, and are also increasingly the targets of global climate change policies. The intervention of postcolonial feminist theory combined with feminist political ecology has the potential to bring forward women’s seldom-heard experiences of climate change in these valuable ecosystems. This work supports previous feminist political ecology scholarship focused on understanding women’s complicated relationships to the environment and the gendered effects of climate change policies, while challenging dominant conservation discourse around women as a monolithic group. This thesis focuses …


Catastrophic Futures, Robby Hardesty Jan 2018

Catastrophic Futures, Robby Hardesty

Theses and Dissertations--Geography

By means of a peculiar magic, insurance preserves the quantified value of capital through destructive, contingent events. The principal subjects of this project, global reinsurers, stand at the end of a long line of loss claims, holding capital together as forces threaten to tear it apart. The apocalyptic imaginaries of climate change portend events that will be increasingly destructive to capital, and insurers counter with new products and narratives. In examining reinsurers and the catastrophes they protect against, this project questions how novelty emerges from the eternal return of the same. I show how power is inscribed in the landscape, …


“One More Way To Sell New Orleans”: Airbnb And The Commodification Of Authenticity Through Local Emotional Labor, Ian Spangler Jan 2018

“One More Way To Sell New Orleans”: Airbnb And The Commodification Of Authenticity Through Local Emotional Labor, Ian Spangler

Theses and Dissertations--Geography

Since 2014, Airbnb has been the poster-child for an impassioned debate over how to best regulate short-term home rentals (STR’s) in New Orleans, Louisiana. As critical perspectives toward on-demand economic practice become increasingly common, it is important to understand how the impacts of STR platforms like Airbnb extend beyond the realm of what is traditionally conceptualized as the economic (i.e., pressure on housing markets). In this thesis, I explore the ways in which Airbnb recalibrates the spatial and temporal rhythms of everyday neighborhood life for people external to the formal trappings of an STR contract. Drawing in particular on theories …

Leveraging Overhead Imagery For Localization, Mapping, And Understanding, Scott Workman Jan 2018

Leveraging Overhead Imagery For Localization, Mapping, And Understanding, Scott Workman

Theses and Dissertations--Computer Science

Ground-level and overhead images provide complementary viewpoints of the world. This thesis proposes methods which leverage dense overhead imagery, in addition to sparsely distributed ground-level imagery, to advance traditional computer vision problems, such as ground-level image localization and fine-grained urban mapping. Our work focuses on three primary research areas: learning a joint feature representation between ground-level and overhead imagery to enable direct comparison for the task of image geolocalization, incorporating unlabeled overhead images by inferring labels from nearby ground-level images to improve image-driven mapping, and fusing ground-level imagery with overhead imagery to enhance understanding. The ultimate contribution of this thesis …


Investigation Of Hydrologic Change In The South Fork Edisto Basin 1981-2016, Alexander Preston Butler Jan 2018

Investigation Of Hydrologic Change In The South Fork Edisto Basin 1981-2016, Alexander Preston Butler

Theses and Dissertations

Increased demands on water resources coupled with an increased awareness of the need to preserve environmental flows have led to a need to understand how anthropogenic activities may have impacted water resources in South Carolina. The South Fork of the Edisto River has been facing increasing demands for both surface water and groundwater. This research investigated if and why hydrologic change, as indicated by a change in the rainfall/ stream discharge relationship, occurred in the South Fork Edisto Basin, in South Carolina, between the years 1980-2016. A double-mass curve analysis, which is corroborated by runoff coefficients, indicates that a fundamental …


Measuring Agricultural Drought And Uncertainty In Future Drought Projections, Junyu Lu Jan 2018

Measuring Agricultural Drought And Uncertainty In Future Drought Projections, Junyu Lu

Theses and Dissertations

Drought is a devastating, recurring, and widespread natural hazard that affects natural habitats, ecosystems, and economic and social sectors. Within the agricultural sector, droughts can reduce soil-water availability, affect water and soil quality, contribute to crop failures and pasture losses, and severely reduce crop yield. Effective drought quantification and early warning are critical for drought risk adaptation. Moreover, future drought risks could be exacerbated due to climate change. Modeling how climate change might influence future drought risks is of great importance in natural resources and water resources planning management. This dissertation has three parts. 1) The first part compares and …


Why Is No One Getting A Weave Of An Afro: Examining Culture, Economy, And Domestic Human Hair Consumption By African American Women, Brittani Young Jan 2018

Why Is No One Getting A Weave Of An Afro: Examining Culture, Economy, And Domestic Human Hair Consumption By African American Women, Brittani Young

Theses and Dissertations

The market for human hair, in the form of wigs and hair weaves, has grown exponentially, with African American women comprising a significant portion of consumers in the United States. Similar to other markets, the structure and patterns of hair consumption by African American women is the result of a variety of historical and geographical factors. In this thesis I investigate the role of African American women in the global human hair trade, and consider the implications of contemporary discourses around ‘good’ and ‘black’ hair in order to better understand trade in human hair. In particular, I use a combination …

Virunga: Guns, Gorillas, And The Construction Of Transnational Natures, Adriana Disilvestro Jan 2018

Virunga: Guns, Gorillas, And The Construction Of Transnational Natures, Adriana Disilvestro

Honors Theses

The recent western media attention surrounding Virunga National Park in the Democratic Republic of Congo, has brought up significant scholarly questions about the discursive portrayal of “ideal” Natures. In this thesis, I undertake a discursive analysis of western media materials about Virunga National Park in order to understand how ideas of Nature are transnationally constructed. In order to do this, undertake an analysis of the western oriented discursive material associated with three socio-political processes within the park: green militarization, gorilla trekking, and the ecotourist industry. Ultimately, I conclude that the discursive material portrays a highly spectacularized and commodified “ideal” nature, …


Geomorphic Consequences Of Hydroelectricity And Transportation Development Near Celilo Falls, Lower Mid-Columbia River, Washington, Noah I. Oliver Jan 2018

Geomorphic Consequences Of Hydroelectricity And Transportation Development Near Celilo Falls, Lower Mid-Columbia River, Washington, Noah I. Oliver

All Master's Theses

Along the Columbia River, hundreds of miles of transportation infrastructure and over sixty hydroelectric dams have been constructed. This altered a rich cultural landscape with evidence of 10,000 years of continuous occupation. Researchers have attempted to understand the impacts of anthropogenic factors on the Columbia River, focusing on the riverine environment. However, the effect of transportation and hydroelectricity developments to eolian landforms on the floodplains and adjoining slopes have not been studied. Focusing on 2,800 acres near Celilo Falls, this study 1) establishes a baseline condition of eolian landforms from 1805 to 1900; 2) conducts an air photo increment analysis …


Residential Solar In Washington State, Sam Pfeifer Jan 2018

Residential Solar In Washington State, Sam Pfeifer

All Master's Theses

Electricity generated through residential solar provides a low carbon source of electricity. However, diffusion of residential solar remains low across the United States. Growing this diffusion takes an understanding of localized uptake trends, which can focus policy and business efforts to help increase residential solar market penetration. This is the first research to investigate residential solar uptake in Washington State and to examine environmental education as a potential driver of residential solar uptake. Through a snapshot analysis which considers environmental, economic, education, and cultural variables the present research fills this gap. Triangulated results include mapping of variables, ordinary-least squares multiple …

Subsidiary Development Of New Technologies: Managing Technological Changes In Multinational And Geographic Space, Anupama Phene, Stephen Tallman Jan 2018

Subsidiary Development Of New Technologies: Managing Technological Changes In Multinational And Geographic Space, Anupama Phene, Stephen Tallman

Management Faculty Publications

This study explores the co-evolution of the subsidiaries of the multinational firm with their global organizations and geographic locations. We examine when and how subsidiaries make sense of and respond to technological changes in these environments to expand their scope and develop new technologies. Using the concept of local search, we propose that technological changes in a subsidiary’s parent firm and host country, in areas specific to the subsidiary’s expertise and at the broad industry level, have differential effects on subsidiary development of new technologies. We further propose that subsidiary innovative capability acts as a moderator, enabling subsidiaries to respond …

La Dialéctica, David Harvey

Publications and Research

Raymond Williams eligió el recurso de pensar ‘mundos posibles’ ficticios para abordar la complejidad de temas relativos al lugar, el espacio y el ambiente. ¿Sin embargo, será que este era un recurso necesario, o más bien una estrategia aleatoria suya para profundizar en el estudio de la teoría de la cultura? Empezaré en este capítulo por demostrar que la estrategia empleada por Williams no es necesaria en absoluto. Espero poder demostrar que la investigación materialista histórica, inducida por un entendimiento dialéctico, puede integrar los temas de lugar, espacio y ambiente (naturaleza) en la teoría social y en la teoría literaria. …

Geografía Abolicionista Y El Problema De La Inocencia, Ruth Wilson Gilmore

Publications and Research

Resumen:

En el presente artículo se analizan las geografías carcelarias en los Estados Unidos, desde el despliegue del capitalismo racial. La geógrafa afroamericana parte de la tesis de que las prisiones contemporáneas son extractivas, es decir, extraen personas y, cuando, en el mejor de los casos, no hacen parte de los altos índices de las muertes prematuras, las expulsan al mundo sin el derecho a ser ellas, dinámica que estimula la circulación rápida de flujos de dinero. Frente a esta topografía anuladora de la vida, la también activista afroamericana reflexiona sobre su experiencia en contra del complejo militar carcelario, el …

Geography

Urban ecosystems are widely hypothesized to be more ecologically homogeneous than natural ecosystems. We argue that urban plant communities assemble from a complex mix of horticultural and regional species pools, and evaluate the homogenization hypothesis by comparing cultivated and spontaneously occurring urban vegetation to natural area vegetation across seven major U.S. cities. There was limited support for homogenization of urban diversity, as the cultivated and spontaneous yard flora had greater numbers of species than natural areas, and cultivated phylogenetic diversity was also greater. However, urban yards showed evidence of homogenization of composition and structure. Yards were compositionally more similar across …
