Crafting Stone Discoidals On The Frontier: Production And Identity In Southwest Virginia, Hamilton Hastie Bryant
Crafting Stone Discoidals On The Frontier: Production And Identity In Southwest Virginia, Hamilton Hastie Bryant
Electronic Theses and Dissertations
Stone discoidals are widely recognized as a class of artifacts associated with Mississippian cultural traditions and even some of its various descendant communities. Excavations at the Carter Robinson site a Fourteenth Century Mississippian frontier site in Lee County Virginia have revealed evidence of the production of stone discoidals. Although craft production in Mississippian societies has been the subject of much debate little to no attention has been given to the production of stone discoidals. The purpose of this thesis is to explicate the method of stone discoidal production at Carter Robinson and to explore how this production was organized overtime …
Improving The Interstate Highway System, Chase Minor
Improving The Interstate Highway System, Chase Minor
Williams Honors College, Honors Research Projects
The Interstate Highway System is the primary transportation network of the United States. The Interstate Highway System has succeeded and failed in certain ways in connecting the United States. It is important that new interstate highways are added so that the United States will be better connected. Several criteria are involved in placing new interstates. New interstates should follow the grid pattern of the existing interstates, with one end of the interstate in between existing interstates so that the interstate starts/ends west of one interstate and east of another (odd-numbered), or north of one interstate and south of another (even-numbered). …
Unbundling Property In Boston’S Urban Food Commons, Oona Morrow, Deborah Martin
Unbundling Property In Boston’S Urban Food Commons, Oona Morrow, Deborah Martin
Geography
Households and community organizations are involved in the creation, use, care, and management of urban spaces, including through food practices such as planting, foraging, harvesting, weeding and pruning at the ambiguous edges of public and private property. Drawing on case studies in Boston, Massachusetts, we examine how commons are articulated through these practices, particularly in relation to multiple dimensions of property rights. Specifically, we ask how food practices can open urban spaces to negotiations around access, responsibility, care, and ownership, especially when (property) ownership is not an end-goal, but a circumstance shaping other practices. Using interviews and participant observation of …

Geography
Residential land is expanding in the United States, and lawn now covers more area than the country’s leading irrigated crop by area. Given that lawns are widespread across diverse climatic regions and there is rising concern about the environmental impacts associated with their management, there is a clear need to understand the geographic variation, drivers, and outcomes of common yard care practices. We hypothesized that 1) income, age, and the number of neighbors known by name will be positively associated with the odds of having irrigated, fertilized, or applied pesticides in the last year, 2) irrigation, fertilization, and pesticide application …
Ngos As Innovators In Extractive Industry Governance. Insights From The Eiti Process In Colombia And Peru, Elisa Arond, Anthony J. Bebbington, Juan Luis Dammert
Ngos As Innovators In Extractive Industry Governance. Insights From The Eiti Process In Colombia And Peru, Elisa Arond, Anthony J. Bebbington, Juan Luis Dammert
Geography
This paper explores NGO participation within the Extractive Industries Transparency Initiative (EITI), a multi-stakeholder governance arrangement focused on generating greater transparency in the governance of extractive industries, and in particular in fiscal arrangements around mining, oil and gas operations. Using the cases of Peru and Colombia, we examine what motivates NGO participation in EITI, how NGOs have pursued innovations within EITI, the extent to which they have succeeded in achieving their goals, and the factors limiting or shaping their achievements. We draw on interviews conducted between 2013 and 2018, participation in global EITI meetings, and secondary material. The paper examines …
Classification Of Aerosol Population Type And Cloud Condensation Nuclei Properties In A Coastal California Littoral Environment Using An Unsupervised Cluster Model, Samuel A. Atwood, Sonia M. Kreidenweis, Paul J. Demott, Markus D. Petters, Gavin Cornwell, Andrew C. Martin, Kathryn A. Moore
Classification Of Aerosol Population Type And Cloud Condensation Nuclei Properties In A Coastal California Littoral Environment Using An Unsupervised Cluster Model, Samuel A. Atwood, Sonia M. Kreidenweis, Paul J. Demott, Markus D. Petters, Gavin Cornwell, Andrew C. Martin, Kathryn A. Moore
Geography Faculty Publications and Presentations
Aerosol particle and cloud condensation nuclei (CCN) measurements from a littoral location on the northern coast of California at Bodega Bay Marine Laboratory (BML) are presented for approximately six weeks of observations during the boreal winter–spring as part of the CalWater-2015 field campaign. The nature and variability of surface (marine boundary layer, MBL) aerosol populations were evaluated by classifying observations into periods of similar aerosol and meteorological characteristics using an unsupervised cluster model to derive distinct littoral aerosol population types and link them to source regions. Such classifications support efforts to understand the impact of changing aerosol properties on precipitation …
From Nativism To White Power: Mid-Twentieth-Century White Supremacist Movements In Oregon, Shane Burley, Alexander Ross
From Nativism To White Power: Mid-Twentieth-Century White Supremacist Movements In Oregon, Shane Burley, Alexander Ross
Geography Faculty Publications and Presentations
Two document cases in the Oregon Historical Society (OHS) Research Library's George Rennar papers contain significant documentation of White supremacist organizations that developed in Oregon during the period between World War I and World War II. In this Research Files article, Shane Burley and Alexander Reid Ross highlight connections found within the collection between the variety of interlinked, racist, and nationalist organizations during that time period. Burley and Ross argue that while “membership numbers remained relatively small, these organizations provided a crucial link to the development of radical right-wing groups during the postwar era.”
The Mortality Response To Absolute And Relative Temperature Extremes, Scott C. Sheridan, Cameron C. Lee, Michael J. Allen
The Mortality Response To Absolute And Relative Temperature Extremes, Scott C. Sheridan, Cameron C. Lee, Michael J. Allen
Political Science & Geography Faculty Publications
While the impact of absolute extreme temperatures on human health has been amply studied, far less attention has been given to relative temperature extremes, that is, events that are highly unusual for the time of year but not necessarily extreme relative to a location's overall climate. In this research, we use a recently defined extreme temperature event metric to define absolute extreme heat events (EHE) and extreme cold events (ECE) using absolute thresholds, and relative extreme heat events (REHE) and relative extreme cold events (RECE) using relative thresholds. All-cause mortality outcomes using a distributed lag nonlinear model are evaluated for …
Application Of Geodetector Method And Other Statistical Methods To Study Groundwater Vulnerability To Nitrate Contamination In The Central Valley Aquifer, California, Anil Shrestha
Graduate Research Theses & Dissertations
The Central Valley (CV) Aquifer, California is one of the most productive regions of the United States, where large amount of nitrogen fertilizer has been applied for the last few decades to increase the crop productivity. The application of excessive fertilizer has increased the level of nitrate (NO3-N) in the groundwater to above EPA’s maximum contamination level (MCL) of 10 mg/L in several domestic, public and monitoring wells. The concentration of nitrate in the groundwater can vary spatially depending on the local nitrogen sources, aquifer characteristics and geochemical condition of the area. The changing hydrogeological conditions of the valley due …
Unmanned Aerial-Vehicle-Based Measurement Of Urban Forests, Earle W. Isibue
Unmanned Aerial-Vehicle-Based Measurement Of Urban Forests, Earle W. Isibue
Graduate Research Theses & Dissertations
Human and natural forces continually act on urban forests to producing changes that leading to trees being removed or replanted. Therefore, to manage the urban forest effectively, periodic inventories are needed to ensure that information about the urban forest is current and comprehensive. This task has traditionally been accomplished by manual ground-based field surveys, or more recently by lidar; however, these methods are expensive, either in terms of time, labor, or cost. This project proposes a novel method of using Unmanned Aerial Vehicles (UAVs) to more accurately measure urban tree height and trunk diameter than is currently possible using conventional …

The Short-Term Effects Of Interstate Highways On Small Rural Communities: A Case Study Of I-39, I-49 And I-72, 1990 To 2000, John Paul Metelko
Graduate Research Theses & Dissertations
The presence of interstate highways in rural areas improves access to nearby rural
communities and changes those communities’ spheres of influence. Research into
understanding how improved access from interstate highways affects rural communities
is needed. This case study was designed to investigate how rural communities changed
on the basis of population, vacancy, median home value, and median contract rent in the
short term after an interstate highway was completed nearby in the early 1990s.
The communities included in this study are incorporated cities, towns, villages
and census-designated places in non-metropolitan counties with at least one incorporated
city, town, village and …
A Climatology Of Quasi-Linear Convective Systems In The U.S., Jacob Adam Strohm
A Climatology Of Quasi-Linear Convective Systems In The U.S., Jacob Adam Strohm
Graduate Research Theses & Dissertations
Quasi-linear convective systems, or QLCSs, are a common, organized thunderstorm mode in the U.S. Over the last fifty years, severe weather research has focused on the supercell, but, recently, QLCSs have become an increasingly important area of study. Researchers and operational meteorologists realize that this morphology is difficult to forecast and may be responsible for a large proportion of the severe weather reports in the eastern two-thirds of the U.S. This study seeks to determine the degree to which QLCSs threaten humans and their assets by, first, assessing their climatology and, second, measuring their contribution to the severe report record. …
Long-Term Urban Forest Cover Change Detection With Object Based Image Analysis And Random Point Based Assessment, Raoul Blackman
Long-Term Urban Forest Cover Change Detection With Object Based Image Analysis And Random Point Based Assessment, Raoul Blackman
All Graduate Theses, Dissertations, and Other Capstone Projects
The urban forest provides various ecosystem services. Urban tree canopy cover measurement is the most basic quantification of ecosystem services. There have been few studies focused on long-term high-resolution urban forest change analysis. Further, few if any of these studies have compared object based image analysis (OBIA) and random point based assessment for determination of urban forest cover. The research objective is to define the urban forest canopy area, location, and height within the City of St Peter, MN boundary between 1938 and 2019 using both the OBIA and random point based methods with high spatial-resolution aerial photographic images and …
Adaptation Under The Canopy: Coffee Cooperative And Certification Contributions To Smallholder Livelihood Sustainability In Santa Lucía Teotepec, Oaxaca, Meghan C. Montgomery
Adaptation Under The Canopy: Coffee Cooperative And Certification Contributions To Smallholder Livelihood Sustainability In Santa Lucía Teotepec, Oaxaca, Meghan C. Montgomery
Graduate Student Theses, Dissertations, & Professional Papers
The collapse and reorganization of global coffee markets associated with the “coffee crisis” have had profound, negative impacts on smallholder producer livelihoods throughout the world. In Mexico, the collapse of the International Coffee Agreement (ICA) coincided with withdrawal of government support for agriculture, which devastated producers dependent on coffee for their livelihoods. Smallholders responded by shifting livelihood strategies to diversify income, migrating, and converting primary forest cover to subsistence crops and pasture to support household livelihood security. In some instances, producers also joined or formed cooperative organizations to access specialty certifications that offer higher priced markets, extension information, and other …

Middle To Late Holocene (7200-2900 Cal. Bp) Archaeological Site Formation Processes At Crumps Sink And The Origins Of Anthropogenic Environments In Central Kentucky, Usa, Justin Nels Carlson
Theses and Dissertations--Anthropology
Though some researchers have argued that the Big Barrens grasslands of Kentucky were the product of anthropogenic land clearing practices by Native Americans, heretofore, this hypothesis had not been tested archaeologically. More work was needed to refine chronologies of fire activity in the region, determine the extent to which humans played a role in the process, and integrate these findings with the paleoenvironmental and archaeological record. With these goals in mind, I conducted archaeological and geoarchaeological investigations at Crumps Sink in the Sinkhole Plain of Kentucky. The archaeological record and site formation history of Crumps Sink were compared with environmental …

Boundaries And Policing: Space, Jurisdictions, And Roles In The Collection Of Official Crime Data, Cynthia Suzanne Barnett-Ryan
Graduate Theses, Dissertations, and Problem Reports (ETD)
The Uniform Crime Reporting (UCR) Program is a law enforcement statistical system open to unreported information due to its voluntary nature. As such, there need to be a valid and accepted means to estimate official reports of crime for those different levels of geography where reporting may be incomplete. Current methods of imputing and modeling UCR data, which have not been updated since the 1960s, are based upon conceptualizations of law enforcement agencies that may no longer be valid. These older models do not appropriately represent the law enforcement assessment of space and place and its effects on discretionary recording …
Object-Based Supervised Machine Learning Regional-Scale Land-Cover Classification Using High Resolution Remotely Sensed Data, Christopher A. Ramezan
Object-Based Supervised Machine Learning Regional-Scale Land-Cover Classification Using High Resolution Remotely Sensed Data, Christopher A. Ramezan
Graduate Theses, Dissertations, and Problem Reports (ETD)
High spatial resolution (HR) (1m – 5m) remotely sensed data in conjunction with supervised machine learning classification are commonly used to construct land-cover classifications. Despite the increasing availability of HR data, most studies investigating HR remotely sensed data and associated classification methods employ relatively small study areas. This work therefore drew on a 2,609 km2, regional-scale study in northeastern West Virginia, USA, to investigates a number of core aspects of HR land-cover supervised classification using machine learning. Issues explored include training sample selection, cross-validation parameter tuning, the choice of machine learning algorithm, training sample set size, and feature selection. A …

Utilization Of Various Methods And A Landsat Ndvi/Google Earth Engine Product For Classifying Irrigated Land Cover, Andrew Nemecek
Graduate Student Theses, Dissertations, & Professional Papers
Methods for classifying irrigated land cover are often complex and not quickly reproducible. Further, moderate resolution time-series datasets have been consistently utilized to produce irrigated land cover products over the past decade, and the body of irrigation classification literature contains no examples of subclassification of irrigated land cover by irrigation method. Creation of geospatial irrigated land cover products with higher resolution datasets could improve reliability, and subclassification of irrigation by method could provide better information for hydrologists and climatologists attempting to model the role of irrigation in the surface-ground water cycle and the water-energy balance. This study summarizes a simple, …

East Chicago Politics: A Cornucopia Of Corruption, Tina Ebenger, Tracey Mccabe
Midwest Social Sciences Journal
Despite the comical title, there is a lot of corruption in East Chicago (IN) politics. One mayoral election had to have a “do-over” because of fraudulent absentee ballots, and a former mayor is doing time in jail for using public monies to remodel his home. This cornucopia of corruption extended to the indictment of six public officials (the so-called Sidewalk Six) in East Chicago for misusing public funds for political gain, specifically vote-buying, in the 1999 mayoral reelection of Robert Pastrick. These officials, ranging from a parks superintendent to a city engineer to several city council members, bought votes by …

The Impact Of Perspective In Identifying And Responding To Potential Sexual Misconduct: A Study Of University Students, Nichole Maki Weller, Kathy Parkison, Steven R. Cox, Michael Plummer
Midwest Social Sciences Journal
Recent events have demonstrated a divergent understanding of sexual harassment and other forms of sexual misconduct. Although sociocultural standards regarding sexual misconduct have changed over time, including improved social and workplace standards and protections, it is clear that not everyone views these events through the same lens. The lens is even less clear when potential misconduct is viewed from the distinct perspectives of a “victim” and a “perpetrator.” We surveyed 424 undergraduate and graduate students at Indiana University Kokomo to identify the impact of perspective and various sociodemographic characteristics that may influence perceptions of what is, and is not, sexual …
