Commemorating The Past: Nebraska Museum Practices In Interpreting, Memorializing, And Mythologizing History, Carissa Dowden

Department of Geography: Dissertations, Theses, and Student Research

Commemorative landscapes are spaces that have a symbolic meaning to a group of people and are often identified by a government or by a local community. These landscapes act as “symbolic conduits” to both express and legitimize interpretations of the past, though geographic interpretations are largely limited to the American South and Europe (Alderman and Dywer 2012). This research seeks to better understand landscapes of commemoration and memorialization in Nebraska, specifically how memories of the West and pioneers are constructed and represented within heritage and history institutions. Applying methods in geography, public history and digital humanities, this research considers both …

Reexamining The Desert: A Study Of Place-Based Food Insecurity, Morgan Ryan

Department of Geography: Dissertations, Theses, and Student Research

Food Deserts are areas where individuals lack access to healthy and affordable food. Since 1995, the United States Department of Agriculture has been one of the leading organizations studying the phenomenon of food deserts. However, issues relating to the scale of their analysis limit their ability to gain a nuanced understanding of food insecurity. In the past decade, an increased emphasis has been placed on the importance of local factors that contribute to food insecurity and complicate the large-scale study of the phenomenon. This research explores the various place-based factors shaping food insecurity in Lincoln, Nebraska, by readapting Penchansky and …

The Spatial Organization Of Pre-Colonial African Kingdoms: The Empires Of Ethiopia & Mali, Victoria O. Alapo

Department of Geography: Dissertations, Theses, and Student Research

Pre-Colonial kingdoms in Sub-Saharan Africa were many, and were organized in unique ways. The old Empires of Ethiopia and Mali were selected for this research because of their antiquity and for their contrasts: Ethiopia was an official Christian Empire for about two millennia, while Mali was the quintessential Sub-Saharan Islamic kingdom. Also, both empires possessed documentation written by traditional Africans, in the form of ancient indigenous manuscripts, which predate the colonial period (i.e., the coming of Europeans) by several centuries. In addition, the research analyzes work that has been done by historians and other academics, and incorporates the reports of …

Timing And Formation Of Linear Dunes South Of The Niobrara River Valley, North-Central Nebraska Sand Hills, Ashley K. Larsen

Department of Geography: Dissertations, Theses, and Student Research

The Nebraska Sand Hills is a vast (7500 square kilometer) area of grass-stabilized sand dunes. Larger dunes in the Nebraska Sand Hills formed primarily during the Late Pleistocene, but many underwent widespread reactivation during the Holocene. Recent Optically Stimulated Luminescence (OSL) dating indicates that the last major phase of reactivation in the Sand Hills was during the Medieval Warm Period, approximately 800 years ago. Nevertheless, many questions about the evolution of the dunes remain unanswered, particularly regarding the formation of linear dunes in portions of the Sand Hills.

This study seeks to understand more about the formation of linear dunes …

Spatial Analysis Of Ethnic And Racial Segregation In The Chicago Metropolitan Area, 2000 - 2014, Roy Yao

Department of Geography: Dissertations, Theses, and Student Research

Racial segregation has long been a great concern in the United States. Scholars study and measure racial segregation over different time periods to trace the changing patterns of racial segregation. Chicago, as the nation’s third largest city, also ranked on top of the most segregated cities. Previous studies measured racial segregation in Chicago only numerically; few studies have used geospatial statistic methods to identify racial segregation patterns in the Chicago metropolitan area. This study uses “Hotspot Analysis” (Getis Ord Gi*) to identify Chicago’s most recent segregation patterns among four major ethnic and racial groups: White, African American, Hispanic and Asian. …

Utilizing A Consumer-Grade Camera System To Quantify Surface Reflectance, Joseph J. Lehnert

Department of Geography: Dissertations, Theses, and Student Research

Consumer-grade camera systems are often employed in aerial remote sensing to provide insight into patterns and processes of interest to science and industry, a trend that has largely been encouraged by the rapid growth of the small unmanned aircraft system (sUAS) industry. However, little research exists on the ability of these systems to accurately measure surface reflectance in specific wavebands, a crucial consideration for many remote sensing applications. This research was conducted on the premise that with proper equipment and calibration techniques consumer-grade cameras would be capable of accurately measuring surface reflectance in user-defined wavebands of interest. A stereo-pair, Fujifilm …

Alluvial fills underlying the Platte River Valley in Nebraska record the geologic history of the Platte River in the late Quaternary. This study investigated the alluvium underlying the valley near the cities of North Platte and Kearney, Nebraska. Data obtained from sediment cores drilled in the alluvial deposits was used to investigate the changes in Platte River dynamics on a glacial – interglacial timescale. Optically Stimulated Luminescence (OSL) dating was used to determine burial ages of recovered sediments and to quantify the thicknesses of the late Pleistocene and Holocene alluvial fills at each study area. Our geochronology depicts considerable differences …

A Research Framework For The Geographic Study Of Exotic Pet Mammals In The Usa, Gabrielle C. Tegeder

Department of Geography: Dissertations, Theses, and Student Research

Exotic animals are not well-represented in geographic studies, even in the emerging sub-field of animal geography. With the dearth of exotic animal studies, and the relevance of exotic pets in the public consciousness and in the news, a basic, introductory study such as this is necessary to begin examining the myriad ways in which exotic pets intersect with, and have influence in, both the site and situation of modern human-oriented environments.

Exotic pet attack incidents and both state and federal laws regarding the private ownership of exotic mammals as pets were examined in detail within the scope of this research. …

A Study Of Social Capital And Its Relationship With Dwelling Structure And Environment Based On An Empirical Analysis Of Lincoln, Nebraska, Jeehoon Kim

Department of Geography: Dissertations, Theses, and Student Research

Social capital is described as the concept of social network or social interaction among residents in a neighborhood. In times past, physical environment factors enhancing the level of social capital were main issues to researchers: land-use type and neighborhood design. However, based on various benefits gained from social capital theory, it is needed to study about the influence of social capital. Thus, the impact of social capital on the physical urban environment is investigated in this dissertation research in order to make more livable, healthier, and more active community. Most researches dealing with social capital and housing condition have not …

Department of Geography: Dissertations, Theses, and Student Research

Firearm use in the United States has long been of great concern and at the center of many debates. Most research, however, has either focused on the use of firearms in violent crimes or the availability of firearms compared to the violent crime rates. Few studies have focused on the theft of firearms or the relationships between stolen firearms and crime. Using seven years of data collected Lincoln, Nebraska Police Department, this thesis focuses on the geospatial dimensions of firearm thefts and recoveries. Specific attention is given to the relationship firearm thefts and recoveries have with gun-related crimes, violent crimes, …

Geographic Variation Of Health Care Spending On Heart Failure In Metropolitan Areas, Kevin Mcmillan

Department of Geography: Dissertations, Theses, and Student Research

The costs of healthcare have long been a concern in the United States. It is well known that these costs vary geographically, but attempts to explain this variation have been met with limited and varied success. This is partly attributable to the fact that data available have restricted analyses to assessing the issue to using Medicare cost per beneficiary. In June, 2013, the Center for Medicare and Medicaid Services (CMS) released new Medicare data that detailed the charges and payments made to hospitals throughout the United States in 2011. In this thesis, this new dataset was used to examine costs …

Building A Gis Model To Assess Agritourism Potential, Brian G. Baskerville

Department of Geography: Dissertations, Theses, and Student Research

Rural areas of the world are developing and implementing tourism programs to diversify and reinvigorate their local economies. Often, these programs focus on privately-held lands in largely agricultural regions. In some countries, tourism development strategies have combined agriculture and tourism to create a new industry – agritourism. This industry, although not new in the United States, is still in its nascent stages. Before starting an agritourism enterprise, farmers and ranchers must consider the various factors that will likely influence their potential for long-term success. These factors can be grouped into 1) farm-specific factors such as an operator’s personality or the …

"We Shall Meet Beyond The River": An Analysis Of The Deathscape Of Brownville, Nebraska, Ashley J. Barnett

Department of Geography: Dissertations, Theses, and Student Research

Gravestone studies have traditionally focused on the East Coast, particularly the Northeast, because of the long Euro-American settlement history in that region and because of a landmark 1966 study produced by Edwin Dethlefsen and James Deetz which focused on this region. Significantly less attention has been paid to the interior of the continent, particularly the Great Plains. This study analyzes the temporal variations in gravestone iconography and inscriptions to determine major cultural shifts that took place in Brownville, Nebraska, from the town’s founding in 1854 to the present. 1,224 gravestones in Walnut Grove Cemetery were recorded and analyzed for the …

Exploring The Nature Of Space For Human Behavior In Ordinary Structured Environments, Molly Boeka Cannon

Department of Geography: Dissertations, Theses, and Student Research

What is the nature of the built environment? Built environments are the settings within which people carry out activities and emerge from the specific combining of spatial conditions with specific social content for the setting. The social content and the spatial conditions form a core-defining relationship that serves to distinguish one structured setting from another. A core-defining relationship such as this refers to the essence of the built environment. What are the implications for human behavior that emerge from conceptualizing built environments in this manner? I argue that space, through its essential relationship with the contexts of daily living (i.e. …

A Historical Geography Of Sand Island 1870 - 1944, Lucas P. Johnson

Department of Geography: Dissertations, Theses, and Student Research

This thesis examines the settlement of Sand Island, one of two permanent colonies included within Lake Superior’s Apostle Islands archipelago. Following the introduction and literature review, a summary of Sand Island’s geology, climate and biological features is presented, serving to construct a baseline upon which to build a discussion of the island’s communal life. This foundation gives context to the seventy-four year struggle faced by the predominantly Norwegian immigrants adapting to that environment. It also serves to assist future scholars in studying wilderness recovery after what today is nearly an eighty year absence of the farmer’s plow. Chapter Four includes …

Proximal Sensing As A Means Of Characterizing Phragmites Australis, Travis Yeik

Department of Geography: Dissertations, Theses, and Student Research

Phragmites australis is an invasive wetland weed found throughout much of the United States. Documenting and mapping the growth and spread of this emergent macrophyte can be an important step in developing and implementing successful management strategies. Characterizing the phenology of a vegetation species with a sensor capable of hyperspectral resolution, positioned at close proximity to the canopy of interest, is often a first step necessary for understanding the basic species-specific reflectance patterns, and for quantifying the manner in which light interacts with the plants comprising particular communities. Spectral data over a P. australis canopy were collected during 22 field …

Multi-Temporal Analysis Of Crop Biomass Using Selected Environmental Variables And Remote Sensing Derived Indices, Nwakaku M. Ajaere

Department of Geography: Dissertations, Theses, and Student Research

Measuring biomass in crops is important for yield prediction, nutrient management and analysis of carbon sequestration. Studying crop phenology via biomass can also provide insight into not only the state of the ecosystem but also environmental factors which may affect crop growth. Remote sensing techniques, as an alternative to traditional in-situ sampling methods for biomass assessment, provide potentially more efficient data acquisition and cost-effective procedures. Numerous vegetation indices (VI) have been developed which use spectral reflectance data to measure plant biophysical characteristics. The first objective of this research was to examine the correlation between crop biomass and selected environmental variables …

Levels Of Response In Experiential Conceptualizations Of Neighborhood: The Potential For Multiple Versions Of This Place Construct, Cynthia M. Williams

Department of Geography: Dissertations, Theses, and Student Research

In the literature, numerous theoretical perspectives have defined and interpreted what is meant by “neighborhood.” A criticism of these perspectives is a lack of a universal definition, with no one-to-one empirical counterpart. The intent of this dissertation is to develop experiential conceptualizations of the construct neighborhood. Residents, those who experience and interact on a daily bases will provide the meaning and interpretation of what is meant by neighborhood.

The “levels of response” are the means of identifying and interpreting the systematic differences in the cognitive processing involved in the construal of neighborhood. Five cognitive levels of response were identified: Affective, …

Preservation Ethics In The Case Of Nebraska’S Nationally Registered Historic Properties, Darren Michael Adams

Department of Geography: Dissertations, Theses, and Student Research

This dissertation focuses on the National Register of Historic Places and considers the geographical implications of valuing particular historic sites over others. Certain historical sites will either gain or lose desirability from one era to the next, this dissertation identifies and explains three unique preservation ethical eras, and it maps the sites which were selected during those eras. These eras are the Settlement Era (1966 – 1975), the Commercial Architecture Era (1976 – 1991), and the Progressive Planning Era (1992 – 2010). The findings show that transformations in the program included an early phase when state authorities listed historical resources …

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 …

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 …
