Analysis Of Simulated And Actual Airborne Remote Sensing Imagery For Characterization Of Surface Water Wave Effects, Charles R. Bostater, Heather Frystacky, Mate Nemes, Luce Bassetti

Ocean Engineering and Marine Sciences Faculty Publications

Simulated and airborne imagery demonstrate the ability to see manmade and natural objects below the water wave surface. Traditional photogrammetric imagery and airborne digital imagery both suffer from a loss in image clarity due to a number of factors, including the forward motion of the airborne platform. Blurring due to this effect can be calculated and an opto-mechanical system has been designed in order to help remove this effect. Forward motion blur can be shown to occur on the order of a several centimeters and calculation results are presented. The system is described and imagery is shown to demonstrate image …

Intersections Of Place, Time, And Entertainment In Rural Nebraska In The Late 19th And Early 20th Centuries, Rebecca A. Buller

Department of Geography: Dissertations, Theses, and Student Research

As newcomers developed Nebraska settlements in the late 19th and early 20th centuries, they began to shape the space. This study explores the intersections of place, time, and entertainment in rural Nebraska from the beginning of European American settlement in the late 19th century to the end of the Great Depression. Through such examinations, we can better understand the historical geographies of individual and collective human experience. With such knowledge, we can then recognize how entertainment reflected social life, sense of place, place attachment, and the intricacies and larger scale trends of race, ethnicity, gender, age, class, nationality, and religion. …

The Very Basics Of Sustainability - An Alternative Viewpoint (Slides With Audio) (Large File! To Speed Up Download, Right-Click On "Download" Link To Save To Own Pc.), Jim Mcgovern

Other resources

This presentation sets out the very basics of ‘sustainability’, although a definition of sustainability is not attempted. Some of the very basics are the context in which the Earth and humankind exist in space and time, the Earth’s climate, the Earth’s population and humankind’s options and choices. The author advocates keeping an open mind on all available options, including the use of oil, gas, coal, tar sands, carbon capture and sequestration, nuclear power etc., as well as the technologies that are more widely considered ‘green’. The author also argues that, in addressing the challenges that humankind faces, globally concerted effort …

Spatio-Temporal Cluster Analysis Of County-Based Human West Nile Virus Incidence In The Continental United States, Ramanathan Sugumaran, Scott R. Larson, John P. Degroote

Faculty Work

Background: West Nile virus (WNV) is a vector-borne illness that can severely affect human health. After introduction on the East Coast in 1999, the virus quickly spread and became established across the continental United States. However, there have been significant variations in levels of human WNV incidence spatially and temporally. In order to quantify these variations, we used Kulldorff's spatial scan statistic and Anselin's Local Moran's I statistic to uncover spatial clustering of human WNV incidence at the county level in the continental United States from 2002– 2008. These two methods were applied with varying analysis thresholds in order …

Complexity In Water And Carbon Dioxide Fluxes Following Rain Pulses In An African Savanna, Christopher A. Williams, Niall Hanan, Robert J. Scholes, Werner Kutsch

Geography

The idea that many processes in arid and semi-arid ecosystems are dormant until activated by a pulse of rainfall, and then decay from a maximum rate as the soil dries, is widely used as a conceptual and mathematical model, but has rarely been evaluated with data. This paper examines soil water, evapotranspiration (ET), and net ecosystem CO2 exchange measured for 5 years at an eddy covariance tower sited in an Acacia-Combretum savanna near Skukuza in the Kruger National Park, South Africa. The analysis characterizes ecosystem flux responses to discrete rain events and evaluates the skill of increasingly complex "pulse models". …

Resistant Place Identities In Rural Charleston County, South Carolina: Cultural, Environmental, And Racial Politics In The Sewee To Santee Area, Cassandra Y. Johnson, Angela C. Halfacre, Patrick T. Hurley

Environment and Sustainability Faculty Publications

The cultural and political implications of landscape change and urban growth in the western U.S. are well-documented. However, comparatively little scholarship has examined the effects of urbanization on sense of place in the southern U.S. We contribute to the literature on competing place meanings with a case study from the rural “Sewee to Santee” region of northern Charleston County, SC. Our research highlights conflicting cultural, environmental, and racial politics and their roles in struggles over place meanings. Using focus groups, interviews with elected officials, and participant observation, we document initial African American resistance and eventual compliance with the prevailing anti-sprawl …

Using Geographically Weighted Regression Models To Analyze Crash Harm, Libin Zheng

Civil & Environmental Engineering Theses & Dissertations

Society pays a high cost for collisions in terms of property damage, injuries and loss of life. This paper has two objectives. One is to examine various factors associated with harm caused by highway collisions. Both global OLS and local GWR models are provided to identify specific variables influencing crash harm. Another objective is to demonstrate the use of a Geographically Weighted Regression (GWR) method in this complex safety problem, which can estimate models for each crash location and show spatial variation. The results show that the GWR model is a significant improvement on the OLS model; the test for …

Filming Postbourgeois Suburbia: Office Space And The New American Suburb, Shaun Huston

Geography Faculty Publications and Presentations

The article examines how the depiction of American suburbia in motion pictures illustrates the physical, cultural, and demographic changes in modern suburban society. Particular attention is paid to the portrayal of the suburban landscape in the 1999 film "Office Space," written and directed by Mike Judge. The "polymorphous" landscape of "Office Space" shows single family homes along side office parks, apartments, restaurants and retail spaces. How the film introduces new sources of angst and oppression to contemporary suburbia is assessed. It is suggested that the film highlights the fact that the suburbs Americans actually live in are fundamentally different from …

The Burden Of Fetching Water: Using Caloric Expenditure As An Indicator Of Access To Safe Drinking Water—A Case Study From Xieng Khouang Province, Lao Pdr, Jeff La Frenierre

Electronic Theses and Dissertations

The Millennium Development Goals measure ‘access to improved drinking water’ using an indicator that defines access as the presence of an improved water source within 1 kilometer of a person’s dwelling. This purely linear measurement has significant shortcomings, including a lack of consideration for the difficulty of the terrain being traversed and the weight of the loads being carried. This paper examines in detail the human energy costs associated with fetching water, first using two Lao villages as case studies, then applying a predictive energy expenditure model to measure the potential caloric effect of variations in the age and gender …

‘Buried Beneath The Waves’: Using Gis To Examine The Physical And Social Impact Of A Historical Flood, Mathew Novak, Jason Gilliland

Geography & Environment Publications

Natural disasters such as floods can periodically disturb and destroy the built and social fabric of communities. Despite their importance, specific ramifications of natural disasters can be overlooked in local histories due to a paucity of data. In this article we bring together several disparate sources of data within a historical geographic information system (HGIS) to study certain physical and social details of the flood which devastated the Town of London West, Canada on 11 July 1883. The integration of historical and contemporary data sources allow for the construction of a three-dimensional model of where the flood likely occurred. With …

The Determinants Of First Nation And Inuit Health: A Critical Population Health Approach, Chantelle A.M. Richmond, Nancy A. Ross

Aboriginal Policy Research Consortium International (APRCi)

Environmental dispossession disproportionately affects the health of Canada’s Aboriginal population, yet little is known about how its effects are sustained over time. We use a critical population health approach to explore the determinants of health in rural and remote First Nation and Inuit communities, and to conceptualize the pathways by which environmental dispossession affects these health determinants. We draw from narrative analysis of interviews with 26 Community Health Representa- tives (CHRs) from First Nation and Inuit communities across Canada. CHRs identified six health determinants: balance, life control, education, material resources, social resources, and environmental/ cultural connections. CHRs articulated the role …

Impacts Of Climate Change And Urban Development On Water Resources In The Tualatin River Basin, Sarah Praskievicz

Dissertations and Theses

Potential impacts of climate change on the water resources of the Pacific Northwest of the United States include earlier peak runoff, reduced summer flows, and increased winter flooding. An increase in impervious surfaces, accompanied by urban development, is known to decrease infiltration and increase surface runoff. Alterations of flow amount and pathways can alter water quality through dilution or flushing effects. I used the United States Environmental Protection Agency's Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) modeling system to investigate the relative importance of future climate change and land use change in determining the quantity and quality of …

The Problem With Eating Money: Remittances And Development Within Senegal's Muridiyya, Rebecca F. Sheff

Political Science Honors Projects

Contemporary development theory is poorly equipped to understand remittance-based development occurring in transnational spaces that partially escape the control of the state. An extended case study of the Muridiyya, a Sufi brotherhood in Senegal, reveals how collective remittances from Mouride transmigrants become tools for community-level development when channeled through transnational religious associations. I argue that remittance-based development projects transform the political, economic, and social contexts in which they are embedded, including the relationship between the Muridiyya and the state. Development theory must be reconceptualized to account for how remittance-based development defies conventional understandings of the scales of economic and social …

At Risk? Exploring The Relationship Between Hiv-Related Knowledge And Risky Behavior In Young Females In Jamaica., Christine E. Chung

Geography Honors Projects

Young females are at three times higher risk of contracting HIV than their male counterparts in Jamaica. Using Jamaica’s 2004 Knowledge, Attitudes, Behaviour and Practices survey, this research investigates factors contributing to HIV/AIDS-related risky behaviors of young females. Risk perception as a function of knowledge and as an influence on behavior is also examined. The findings reveal that only older females, 25 to 49 years, practice safer behaviors in response to increased knowledge. This highlights the disjunction between knowledge and behavior, emphasizing the need for a holistic approach to addressing the social context within which adolescents are put at risk.

Refugees, Hiv/Aids And Access To Medical Care: A Case Study Of Cairo, Egypt, Anna Popinchalk

Geography Honors Projects

Urban refugees in Egypt are at high risk for HIV/AIDS because of the lack of adequate health resources, social stability and the intense stigma and discrimination surrounding HIV/AIDS. Based on a literature review and semi-structured interviews conducted in Cairo, Egypt, this paper uses a vulnerability perspective to examine the challenges facing HIV-positive refugees in accessing necessary medical care. The combination of policy, structural forces and social relations results in a chain of causation that marginalizes refugees in Egyptian society. These social processes results in unequal access to health resources for refugees, thereby increasing their potential exposure to HIV transmission. This …

“The Bus Stops Here”: Place-Making And Transit Justice Issues In The Twin Cities Public Bus Network, Megan A. Macpherson

Geography Honors Projects

This project engages the formation of place-narratives within the Metro Transit bus system by examining the structural factors and individual agents shaping a passenger’s experience of the bus. Using qualitative and quantitative methods, I bring together the literatures of transportation geography, and cultural/feminist geographies. Major themes from my research include the bus as a theater of performance/theater of conflict, the bus as a gateway to public life for those with limited mobility, and the bus as a relational space for specific passenger groups. Additionally, this project explores the significance of place within transit justice work in the Twin Cities. I …

Using Archetypal Metaphor To Analyze Cultural Landscape: A Chlilean Case Study, Cari Bourette

Masters Theses & Specialist Projects

In our increasingly complex and interactive world, it becomes ever more difficult to isolate and map the cultural identity of any given region, as bounded and contained cultural places have become a rare occurrence. To further complicate the matter, perspectives, loyalties, and identities shift with time, and appear to shift with circumstance. While cultural conflict per se was not the subject of this study, the ability to quantify differing cultural profiles in one location relative to another may be the beginning of the development of a tool for assessing degrees of difference in neighboring regions, and thus diagnosing the potential …

Growing Change: Local Foods Movements And The Emergence Of Global Social Change, Annie S. Virnig

Political Science Honors Projects

Local foods movements increasingly emerge as social movements with the power to challenge global norms. This paper develops around the question: can local foods movements create holistic sustainability at the global level? I begin by analyzing impetuses behind contemporary local foods movements. I then evaluate sustainability in three case studies – Auroville, India; the Twin Cities, United States; and Southern Africa. I ultimately argue that local foods movements can create sustainable change if they: (1) develop organically within their locale, (2) account for ecological, social, and economic implications of their actions, and (3) build translocal connections across multiple geographic scales.

A River Transformed: Historic Geomorphic Changes Of The Lower Rio Grande In The Big Bend Region Of Texas, Chihuahua, And Coahuila, David James Dean

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Over the last century, the construction and management of large dams and stream-flow diversions, and periodic drought have resulted in significant declines in stream flow of the lower Rio Grande in the Big Bend region. Reductions in mean annual flow and peak discharge have resulted in channel narrowing by the formation of vertically accreting inset floodplains. Narrowing has been temporarily interrupted by infrequent large dam releases greater than 1000 m³/s that have temporarily widened the channel; however, after each of these events, narrowing has resumed. Prior to 1942, floods of this magnitude occurred approximately once every 4 years …

Ethnic Place Making: Thirty Years Of Brazilian Immigration To South Framingham, Massachusetts, Laura Aldea Skorczeski

Dissertations and Theses

Over the past thirty years, Massachusetts has become a hub of Brazilian immigration. Within Massachusetts, the town of Framingham has the highest concentration of Brazilian residents; one census tract in the southern part of this Boston suburb is an astounding 57.4 percent Brazilian. The presence of the Brazilian population in downtown Framingham, also referred to as South Framingham, has transformed the area into a landscape of Brazilian ethnicity.

When Brazilians began arriving in South Framingham in the early 1980s, the downtown Central Business District was a blighted landscape. This thesis analyzes how Brazilian identities have become imprinted on the landscape …
