The Changing Landscape Of A Rural Region: The Effect Of The Harry S. Truman Dam And Reservoir In The Osage River Basin Of Missouri, Melvin Arthur Johnson Dec 2009

The Changing Landscape Of A Rural Region: The Effect Of The Harry S. Truman Dam And Reservoir In The Osage River Basin Of Missouri, Melvin Arthur Johnson

Department of Geography: Dissertations, Theses, and Student Research

The Harry S. Truman Dam and Reservoir project is of immense size. Many thousands of tons of raw materials were required to complete the construction of the dam and relocations. Millions of dollars were spent to acquire land, compensate those who were displaced, and to pay those who were employed in the planning, purchasing, coordinating, defending, and managing the myriad of contractors, contracts, and legal defenses. The affected area of the project is not only complex physically but also socially and economically. It is, therefore, not surprising that the counties studied (Benton, Henry, and St. Clair) would react in different …

Remote Sensing To Detect The Movement Of Wheat Curl Mites Through The Spatial Spread Of Virus Symptoms, And Identification Of Thrips As Predators Of Wheat Curl Mites, Abby R. Stilwell Dec 2009

Remote Sensing To Detect The Movement Of Wheat Curl Mites Through The Spatial Spread Of Virus Symptoms, And Identification Of Thrips As Predators Of Wheat Curl Mites, Abby R. Stilwell

Department of Entomology: Dissertations, Theses, and Student Research

The wheat curl mite (WCM), Aceria tosichella Keifer, transmits three viruses to winter wheat: wheat streak mosaic virus, High Plains virus, and Triticum mosaic virus. This virus complex causes yellowing of the foliage and stunting of plants. WCMs disperse by wind, and an increased understanding of mite movement and subsequent virus spread is necessary in determining the risk of serious virus infections in winter wheat. These risk parameters will help growers make better decisions regarding WCM management. The objectives of this study were to evaluate the capabilities of remote sensing to identify virus infected plants and to establish the potential …

Detection And Measurement Of Water Stress In Vegetation Using Visible Spectrum Reflectance, Arthur Zygielbaum Dec 2009

Detection And Measurement Of Water Stress In Vegetation Using Visible Spectrum Reflectance, Arthur Zygielbaum

Department of Geography: Dissertations, Theses, and Student Research

At any scale, from a single microbe to the planet that nurtures us, water defines our place in the universe. It provides the hydraulic forces needed to give plants structure, and the medium enabling photosynthesis, the basis for most life on Earth, to occur. Knowledge of plant water status is vital to understanding the state or condition of vegetation, information which is essential to disciplines as diverse as agriculture, geography, and climatology. Non-destructive and remote sensing of plant water status allows the gathering of such information across wide geographic extents and over long periods of time. Monitoring vegetation remotely requires …

Long-Term Agricultural Land-Use Trends In Nebraska, 1866–2007, Tim L. Hiller, Larkin A. Powell, Tim D. Mccoy, Jeffrey J. Lusk Oct 2009

Long-Term Agricultural Land-Use Trends In Nebraska, 1866–2007, Tim L. Hiller, Larkin A. Powell, Tim D. Mccoy, Jeffrey J. Lusk

Great Plains Research: A Journal of Natural and Social Sciences

Although landscape changes from anthropogenic causes occur at much faster rates than those from natural processes (e.g., geological, vegetation succession), human perception of such changes is often subjective, inaccurate, or nonexistent. Given the large-scale land-use changes that have occurred throughout the Great Plains, the potential impacts of land-use changes on ecological systems, and the insight gained from knowledge of land-use trends (e.g., to compare to wildlife population trends), we synthesized information related to land-use trends in Nebraska during 1866–2007. We discussed and interpreted known and potential causes of short- and long-term land-use trends based on agricultural and weather data; farm …

Intersections Of Place, Time, And Entertainment In Rural Nebraska In The Late 19th And Early 20th Centuries, Rebecca A. Buller Aug 2009

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. …

Prpl: An Open-Source General-Purpose Parallel Raster Processing Programming Library, Qingfeng Guan Jan 2009

Prpl: An Open-Source General-Purpose Parallel Raster Processing Programming Library, Qingfeng Guan

Department of Geography: Faculty Publications

pRPL is an open-source general-purpose programming library developed by the author to parallelize almost any raster-processing algorithm with any arbitrary neighborhood configuration, and support any data type. This paper introduces the advanced features of pRPL, compares it with other similar programming libraries, and demonstrates the performance of a parallel geographic Cellular Automata (CA) model developed using pRPL with real-world datasets. In conclusion, pRPL effectively reduces the development complexity of parallel programming, and efficiently reduces the computing time.

Stress, Status, And Sociability: Exploring Residential Satisfaction In The Rural Midwest Following Rapid Immigration, James Potter, Rodrigo Cantarero, Amy E. Boren Jan 2009

Stress, Status, And Sociability: Exploring Residential Satisfaction In The Rural Midwest Following Rapid Immigration, James Potter, Rodrigo Cantarero, Amy E. Boren

Architecture Program: Faculty Scholarly and Creative Activity

This investigation examined predictors of residential satisfaction among newly arrived residents (NAR) and long-term residents (LTR) of a rural community following a rapid influx of immigrants into the community. The physical environment, social/cultural aspects of life, and resources and public services were hypothesized to affect perceptions of residential satisfaction. Both LTR and NAR were pleased with environmental attributes, sociocultural attributes, and public services. An inverse relationship was revealed between stress and residential satisfaction. The primary sources of stress for LTR related to economics and social status issues, whereas the primary sources of stress among NAR involved issues concerning family and …

Pilgrimage Places And Sacred Geometries, Robert Stoddard Jan 2009

Pilgrimage Places And Sacred Geometries, Robert Stoddard

Department of Geography: Faculty Publications

Pilgrimage flows, often involving millions of people, attract the attention of scholars seeking to explain these patterns of movement. A multitude of explanations have been attempted, but none has provided an entirely satisfactory understanding about why certain sites attract worshippers to undertake the sacrifices of pilgrimage. It is recognized that, from the perspective of many religious traditions, Earth space is not homogeneous - that specific places are sacred and different from the surrounding profane land. The reasons certain locations are holy and attract pilgrims from afar have long evoked the geographic question: Why are pilgrimage places distributed as they are? …
