Evaluating Spatial Variability Of Precipitation In Kentucky With Exploratory Data Analysis, Daniel Taylor

Masters Theses & Specialist Projects

Spatial variability of precipitation is examined over the state of Kentucky and surrounding areas. The study focuses on the analysis of monthly precipitation totals from the period of 1961-2000. The purpose of the study is to develop a set of indices to represent the spatial variability of the study area for a given month. Various exploratory data analysis methods such as variography, kriging, and cluster analysis were used. The study attempts to quantify the second order (local) effects of the spatial variation of precipitation as a means to provide insight into the prediction of precipitation randomness. This task can be …

Classifying Mollisol Soils Using Hyperspectral Remote Sensing Data, Adil M. Wadia

All-Inclusive List of Electronic Theses and Dissertations

Soil classification is a complex task that involves several factors. Soil classifications that have been published usually need to be updated as soil series definitions and boundaries change over time. Most existing soil classification surveys in the United States, although often very good, lack the required accuracy for selected applications such as precision agriculture. 111 Hyperspectral remote sensing data, with its 100+ bands and very high spectral resolution can help facilitate soil classification detail not achieved through traditional remote sensing methods. The study area selected for research was Wolf Field, near Homer, Champaign County, Illinois, which is a very agriculturally …

Assessing Tmdl Implementation In The Macatawa Watershed, Mi, Using Swat, Laurence Picq

Masters Theses

Lake Macatawa, on the eastern shore of Lake Michigan, has been impaired by nonpoint source pollution from agriculture. A Total Maximum Daily Load (TMDL), developed by the Macatawa Area Coordinating Council and the Michigan Department of Environmental Quality, established a 60% reduction goal in phosphorus load by 2008. While agricultural best management practices have been implemented in the past three years, the local watershed organization has not had the means to evaluate the effectiveness of these practices, and to assess progress made towards the phosphorus reduction goal.

A simulation model, the Soil and Water Assessment Tool (SWAT) was chosen to …

The Smugglers' Landscape: Geography, Route Selection And The Global Heroin Trade, James Dallis Medler

Graduate Program in International Studies Theses & Dissertations

This study focuses on transnational smuggling, and puts forth an analytical framework from the smugglers' perspective with respect to route selection, focusing primarily on aspects of economic, political, and human geography. It is predicated on three interconnected decision-making domains that constitute the smuggler's operational landscape, namely access, risk and connectivity, which interact to drive the smugglers' perceptions of route attractiveness. The first two domains operate reciprocally, primarily at the national level of analysis, and together both shape and are shaped by the third at the transnational level to form a feedback loop. With respect to connectivity, the convention of the …

An Interim Report Of A Viking-Age & Medieval Archaeofauna From Undir Junkarinsfløtti, Sandoy, Faroe Islands, Thomas H. Mcgovern, Colin Amundsen, Sophia Perdikaris, Ramona Harrison, Yekaterina Krivogorskaya

School of Global Integrative Studies: Faculty Publications

Cooperative international excavations at the site of Undir Junkarinsfløtti (27020) in the village of Sandur on the island of Sandoy, Faroe Islands in May 2003 recovered a stratified bone - rich midden deposit extending from the Viking Age to the early medieval period. The animal bone collection contains domestic mammals (cattle, sheep, dog, goat, and pig) and substantial amounts of fish (mainly cod), birds (mainly puffin and guillemot), and shellfish (mainly limpet). While the current collection has the archaeological limitations inherent in column samples, it suggests persistence of substantial pig keeping into the 13th c, and strongly indicates a sustainable …

Risk Factors For Pre-Post Monsoon Cholera Epidemics In Bangladesh From 1992-1994, Rhonda Rae Robb

Dissertations and Theses

The primary objective of this thesis is to differentiate between the risk factors for pre-and post-monsoon cholera epidemics in rural Bangladesh by analyzing the complex interaction between select environmental, cultural/behavioral, and socioeconomic variables over space and time. In rural Bangladesh, cholera epidemics correspond with the annual monsoon: the first, and smallest, occurs between March and June, while the larger cholera peak occurs between September and December. The differences between the spatial and temporal patterns of seasonal cholera are analyzed, and the risk factors are calculated for pre-and post-monsoon cholera epidemics.

The theoretical approach that underlies this medical geographical study is …

Comparing Twenty-Four Years Of Forest Change In Two Communities Of Mexico's Meseta PuréPecha Using Multi-Spectral Satellite Imagery, Kevin Scott Martin

Dissertations and Theses

The Meseta Purépecha, a volcanic plateau in the Mexican state of Michoacan, is home to one of the most species-rich pine forests in the world. Recent increases in demand for forest products has put added pressure on these resources. Though existing research has suggested significant deforestation in the Meseta, there is little information identifying specific areas of decline. This study focuses on two indigenous communities in the Meseta--Pichátaro and Sevina. Both communities have long relied on wood as an economic resource. However, the two communities have reacted differently to increased demand for forest resources. The purpose of this study is …

Community And Land Attachment Of Chagga Women On Mount Kilimanjaro, Tanzania, Elizabeth Parnell Carr

Theses and Dissertations

Chagga women who control land on Mt. Kilimanjaro, Tanzania, have a deep and profound sense of attachment to their lands and homes. This thesis compares their reasons for attachment to the systemic model. The systemic model states that community attachment is dependent on social ties and interactions. The three factors that lead to these ties are length of residence, social status, and age. In-depth interviews with women in 2002 and 2003, a survey from 2002, and field notes from 2002 and 2003 are used to explain the main factors of attachment of women in three villages on the mountain: Mbahe, …

Roadside Memorial Practices: An Examination Of Landscapes Of Commemoration In Warren County, Kentucky, Michael Briggs

Masters Theses & Specialist Projects

Roadside memorials commemorating the death of automobile crash victims are scattered throughout the Kentucky landscape. This persistent cultural practice contains symbolic elements oftentimes indicative of religious connotations. Because there is a constitutional separation of church and government in the United States, these memorials can prelude controversy if located on state-maintained rights-of-way. This study examines Warren County, Kentucky, and analyzes the spatial distribution of these memorials on the landscape and the cultural implications to society because of their ties to death and dying. Scientific research in various fields of psychology, sociology, folk studies, geoscience, and religious studies was analyzed, including religious …

Understanding Perceptions Of Accessibility And Mobility Through Structuration Theory, Mark Graham

Masters Theses & Specialist Projects

Structuration theory in geography states that social systems are reproduced through the relationships between systems, structures, actors and their perceptions. Therefore, understanding the modes through which social systems are reproduced will allow for a clearer understanding of the nature of society. However, much of the relevant social theory has not been empirically tested. Thus, by empirically examining general perceptual differences between different built environments, on a macro and a micro level, it is hoped that the links between perceptions, social structures, and the built environment can be more fully understood. A better understanding of these links will, in turn, allow …

The Wilderness Problem: A Narrative Of Contested Landscapes In San Juan County, Utah, David Banis

Dissertations and Theses

Wilderness preservation has been at the center of debates about public land policy for almost half a century, and nowhere has the controversy been more intractable than in Utah. Despite its vast expanses of unsetded and undeveloped red rock desert, managed primarily by the Bureau of Land Management (BLM), Utah has less designated wilderness than in any other state in the West. In this study, I focus on San Juan County in southeast Utah to study the conflict over the designation of wilderness. The controversy pits local residents and state politicians against state and national environmental groups, with the BLM …

A 15th C. Archaeofauna From Akurvík, An Early Fishing Station In Nw Iceland, Colin Amundsen, Sophia Perdikaris, Matthew Brown, Yekaterina Krivogorskaya, Salena Modugno, Konrad Smiarowski, Shaye Storm, Malgorzata Frik, Monica Koczela, Thomas H. Mcgovern

School of Global Integrative Studies: Faculty Publications

This is a report of analysis of 15th c bone materials from the site of Akurvík in NW Iceland excavated in 1990. A small international project in Árneshreppur district recovered a series of stratified midden deposits associated with small turf structures on an eroding beachfront. Radiocarbon dates identify at least two major phases of occupation and use, one extending into the mid 13th century, and the other dating to the mid 15th century. This report documents the animal bone collection from the later 15th c occupation. Dominated by cod fish, these deposits appear to be the product of seasonal fishery …

From Mission To Megacity: The Changing Concentration Of The Los Angeles City-System, Kerri L. Cosby

Theses and Dissertations

Having an understanding of when, where, and why people settle in an area is crucial in explaining the growth course of a city. However, this cannot be done by looking at a city in isolation. Its surrounding region has a tremendous impact on its development. The purpose of this thesis is to examine the growth of Los Angeles from a regional perspective, called the Los Angeles city-system, which consists of Los Angeles and its hinterland. Connections are made between the history and the geography of the Los Angeles city-system by examining the spatial distribution of population within the region between …

A Spatial Analysis Of The Impact Of Development On Wetland Habitat In Mount Pleasant, South Carolina, Jenna Medlin

Masters Theses & Specialist Projects

In response to growing concerns over wetland habitat loss and the associated impact on water resources, federal and state legislation has been enacted to protect vulnerable wetland habitats from the impacts of humans. In order to examine the efficacy of current coastal resource policy and its implementation, a study was conducted in Mount Pleasant, South Carolina, a coastal city of the Atlantic, focusing on the quantification of wetland habitat change over time within a specific area of interest. The study incorporated an assessment of the effects of escalating population pressures and subsequent urban development on local wetland habitats due to …

Bio-Optical Properties Of The Arctic Waters: Empirical And Theoretical Observations, Jian Wang

OES Theses and Dissertations

Bio-optical observations were made during August 2000 in the Beaufort and Chukchi Seas. Chlorophyll a concentration (Chl) ranged from 0.068 to 18.51 mg chl m⁻³. Both total particulate and phytoplankton absorption at 443 nm were closely correlated with chlorophyll concentration. There is no strong correlation between chlorophyll concentration and absorption by soluble materials or nonpigmented particulates. Absorption, scattering, and attenuation all show strong first-order spectral relationships. Two semianalytical remote sensing reflectance models were evaluated and validated using bio-optical data collected in this region. Both models were proficient at retrieving chlorophyll concentration, phytoplankton absorption coefficients, and particulate backscattering coefficients. …

Citizenship In The Republic Of Ireland: In The Context Of The European Union And The Citizenship Referendum, Cora Bruemmer

Independent Study Project (ISP) Collection

In a world of increased globalization, the importance of citizenship may seem less and less important. However, I would assert that political belonging is becoming ever more important and is undergoing radical changes. The European Union (EU) is rapidly changing people’s understanding of citizenship. Rather than calling themselves Irish, people may soon be calling themselves European instead. Borders between countries are weakening and movement between them is increasing. Today a citizen of Latvia can live and work in Ireland as long as he or she so chooses. These changes in citizenship may actually have great implications for citizenship policy in …

Simply put, a GIS combines layers of information about a place to give you a better …

Inmigración Marroquí En Granada = Morrocan Immigration In Granada, Emily C M O’Neill

Independent Study Project (ISP) Collection

In today’s world of increased globalization and great economic disparities, the discussion of immigration has become all the more controversial, complicated, and relevant. I believe in the right to immigrate. The nation into which one is born strongly determines the destiny of the individual. I was born in the United States, a rich democratic country and subsequently may have greater opportunities than someone from an impoverished nation, this does not mean, however that I have more right to life than the latter. It is a sad reality that people are forced to leave their homeland in search of a better …

Simulating A Chromotomographic Sensor For Hyperspectral Imaging In The Infrared, Anthony J. Dearinger

Theses and Dissertations

Hyperspectral imaging systems passively sense radiant electromagnetic energy from a remote scene to form a three dimension profile of the remote scene. The data contained in this profile describes real images of the remote scene for a certain number of spectral wavelength bands across a finite spectral range of electromagnetic radiation. Typical grating type hyperspectral imaging systems collect spectral electromagnetic radiation in the visible and near infrared spectral range, by incrementally scanning across the spatial extent of the remote scene. The legacy of low optical throughput because of the optical scanning techniques employed in these systems means adapting these systems …

Surveillance Of The Balto-Finnic Speakers: A Geolinguistic Inquiry, Lindsay E. Gwyther

Honors Theses

The Balto-Finnic languages of northeast Europe are part of the larger Uralic language family. Today, there are seven Balto-Finnic speaking nations, two of which govern their own independent sovereignties (Finland and Estonia). The other five nations lie precariously within the territorial borders of Russia and Latvia for the most part. This paper examines the geographic expanse and status of these languages over time and through space and develops a series of maps to better illustrate these patterns. Historical research demonstrates that their distribution has decreased in area, but strengthened and centralized in certain regions, enabling their presence in a predominantly …

Cross-Service Investigation Of Geographical Information Systems, Matthew H. Beverly

Theses and Dissertations

This research investigated the armed services current uses of GIS, and asked the question whether or not a joint GIS program could benefit the DOD. An information technology implementation model was presented as a framework to implement a joint GIS program. It was found that all four armed services use GIS for forward deployments. The Army has its Combat Terrain Information System (CTIS). The Navy's digital nautical charts are a GIS. The Marine Corps has created their Geographically Linked Information Display Environment (GLIDE) program, which is similar to a map repository. Finally, the Air Force has its GeoBase program for …

Investigation Of Geobase Implementation Issues: Case Study Of Information Resource Management, Mario L. Oliver

Theses and Dissertations

Billions of dollars have been wasted on failed information system (IS) projects over the last decade in the private and public sectors. More specifically, the tri-service environment of the U.S. military has not implemented a single successful geospatial IS (GIS). The lack of a service-wide insertion process for GIS was cited as the most significant cause for military GIS failures. GeoBase represents the USAF's most recent GIS implementation. The GeoBase program focuses on Information Resource Management (IRM) and cultural issues. The GeoBase Sustainment Model (GSM), anecdotally developed by GeoBase leadership to reflect implementation issues and the IRM practices of the …

Cultural Geography: By Whom, For Whom?, Lily Kong

Research Collection School of Social Sciences

The "cultural turn," coupled by the "spatial turn" in recent years has drawn significant attention to cultural geography from those in other subdisciplines and disciplines. One might forgive those who sometimes mistake particular research as cultural geography which is in fact conducted by non-geographers or geographers who would not ordinarily identify themselves as cultural geographers. A pointed moment that illustrated this to me was when a sociology colleague insisted that he had read cultural geography, and when asked, indicated that he had read Nigel Thrift and Ash Amin. One interpretation of this is, as Shurmer-Smith (1996) offered through her title …

Agroforestry, Elephants, And Tigers: Balancing Conservation Theory And Practice In Human-Dominated Landscapes Of Southeast Asia, Philip J. Nyhus, R L. Tilson

Faculty Scholarship

Large mammal populations theoretically are best conserved in landscapes where large protected areas are surrounded by buffer zones, connected by corridors, and integrated into a greater ecosystem. Multi-use buffer zones, including those containing complex agroforestry systems, are promoted as one strategy to provide both economic benefits to people and conservation benefits to wildlife. We use the island of Sumatra, Indonesia to explore the benefits and limitations of this strategy. We conclude that conservation benefits are accrued by expanding the habitat available for large mammals but more attention needs to be focused on how to reduce and respond to human–wildlife conflict …
