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

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). …

The Archaeology Of The Postindustrial: Spatial Data Infrastructures For Studying The Past In The Present, Daniel Trepal

Dissertations, Master's Theses and Master's Reports

Postindustrial urban landscapes are large-scale, complex manifestations of the past in the present in the form of industrial ruins and archaeological sites, decaying infrastructure, and adaptive reuse; ongoing processes of postindustrial redevelopment often conspire to conceal the toxic consequences of long-term industrial activity. Understanding these phenomena is an essential step in building a sustainable future; despite this, the study of the postindustrial is still new, and requires interdisciplinary connections that remain either unexplored or underexplored. Archaeologists have begun to turn their attention to the modern industrial era and beyond. This focus carries the potential to deliver new understandings of the …

Criar Y Dejarse Criar: Trans-Situ Crop Conservation And Indigenous Landscape Management Through A Network Of Global Food Neighborhoods, Cass Madden

Capstone Collection

As climate change progresses, global food security is likely to become increasingly threatened and crop biodiversity will be a significant source of resiliency and adaptability. However, these adaptations will only be fully realized through cooperative in situ and ex situ conservation and cultivation of domesticated crops, crop wild relatives, and wild foods. This conservation is best realized in places where communities have the cultural resources to invest meaningfully in the cultivation of native crops, and where the cultivation of those crops can reinforce place-specific livelihoods and identities. To this end, the principal objective of this research is to propose a …

Crown-Level Mapping Of Tree Species And Health From Remote Sensing Of Rural And Urban Forests, Fang Fang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tree species composition and health are key attributes for rural and urban forest biodiversity, and ecosystem services preservation. Remote sensing has facilitated extraordinary advances in estimating and mapping tree species composition and health. Yet previous sensors and algorithms were largely unable to resolve individual tree crowns and discriminate tree species or health classes at this essential spatial scale due to the low image spectral and spatial resolution. However, current available very high spatial resolution (VHR) remote sensing data can begin to resolve individual tree crowns and measure their spectral and structural qualities with unprecedented precision. Moreover, various machine learning algorithms …

Reconciling The Dissonance Between Historic Preservation And Virtual Reality Through A Place-Based Virtual Heritage System., Danny J. Bonenberger

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study explores a problematic disconnect associated with virtual heritage and the immersive 3D computer modeling of cultural heritage. The products of virtual heritage often fail to adhere to long-standing principles and recent international conventions associated with historic preservation, heritage recording, designation, and interpretation. By drawing upon the geographic concepts of space, landscape, and place, along with advances in Geographic Information Systems, first-person serious games, and head-mounted Virtual Reality platforms this study envisions, designs, implements, and evaluates a virtual heritage system that seeks to reconcile the dissonance between Virtual Reality and historic preservation. Finally, the dissertation examines the contributions and …

Geospatial Analysis Of Care And Mortality In The 2014 Liberia Ebola Outbreak, Marion Carlton Kinkade

Walden Dissertations and Doctoral Studies

The Ebola outbreak in West Africa in 2014 to 2016 had more than 28,000 suspected, probable, and confirmed cases. It was the largest Ebola outbreak in history. Of the 28,000 cases in the three Ebola-affected countries, Liberia had 10,000 cases with almost 5,000 deaths. The Ebola Virus Disease (EVD) entered Liberia along the border of Guinea and moved to the capital city of Monrovia where the virus spread. Ebola Treatment Units (ETUs) were constructed throughout the response in locations where there were available facilities versus distance to care challenges. This study examined the association of distance from villages to ETUs …

Employing Natural History Collections In The Aid Of Conservation: Streamlining An Approach To Model Species Distributions En Masse For The Preservation Of Biodiversity, Alice Fornari

Master's Projects and Capstones

Using species distribution models (SDMs) in Natural History Collections (NHCs) can influence how humans implement conservation changes in flora and fauna communities and ecosystems. Through the use of legacy data (old NHCs and their associated locality/collection information), data correction (background data or pseudo absences added to presence-only data), and the SDM software, Maxent (and its associated geographic information systems or GIS projected models), it has been shown that it is feasible to create a low budget protocol/setup to project the past, present and future of species population changes. This has been done in the past few decades as more collections …

Open Source Foundations For Spatial Decision Support Systems, Jochen Albrecht

Publications and Research

Spatial Decision Support Systems (SDSS) were a hot topic in the 1990s, when researchers tried to imbue GIS with additional decision support features. Successful practical developments such as HAZUS or CommunityViz have since been built, based on commercial desktop software and without much heed for theory other than what underlies their process models. Others, like UrbanSim, have been completely overhauled twice but without much external scrutiny. Both the practical and the theoretical foundations of decision support systems have developed considerably over the past 20 years. This article presents an overview of these developments and then looks at what corresponding tools …

Using Deep Learning To Forecast Spatiotemporal Crime Patterns, Shuzhan Fan

LSU Doctoral Dissertations

The distributional patterns of crime occurrences are closely related to their spatial, temporal, and environmental contexts. It has been a hot topic for researchers and crime analysts to discover such complex relationships in order to forecast crime, both spatially and temporally. Many factors play a role in the occurrences of crimes. Conventional crime forecasting research has primarily relied on historical crime records and socioeconomic data, while ignoring the rich social media and other environmental context data. The large volume of data requires a more appropriate forecasting framework with the ability to take in massive multimodal data and possibly achieve better …

The Evacuation Of Phnom Penh During The Cambodian Genocide: Applying Spatial Video Geonarratives To The Study Of Genocide, James A. Tyner, Andrew Curtis, Sokvisal Kimsroy, Chhunly Chhay

Genocide Studies and Prevention: An International Journal

On April 17, 1975 Khmer Rouge soldiers began the forcible evacuation of Phnom Penh, Cambodia’s capital city. The evacuation has been the subject of considerable debate surrounding the Cambodian genocide and remains a topic of prime importance toward the understanding of Khmer Rouge policy and practice. In this field note, we present a geographically-informed account of the evacuation in order to provide a more fine-grained analysis of Khmer Rouge practice. More specifically, employing spatial video geonarratives, we provide a systematic investigation of the evacuation, as retraced by six evacuees. In so doing we contribute also to the emergent use of …

Constructing A Data-Based Mortality Profile For Avian Tower Kills At Telecommunication Towers In Illinois, Rachel Dipietro

Theses and Dissertations

During spring and fall seasons, Neotropical migratory passerines travel nocturnally across the Western Hemisphere between their wintering and breeding grounds, often encountering man-made threats. One hazard that has gained considerable publicity in recent decades is the communication tower. While there have been many tower kill studies recorded, there has been no attempt at predicting the risk of towers based on their different attributes (e.g., height, type of light, landscape placement) spatially on a regional scale. The objective of this study was to create seasonal mortality profile maps in GIS for Illinois, based on tower attributes combined with key factors such …

Finding Ft. Smith And Ft. Star In Smithland, Ky, Austin Valentine, Austin Valentine Jr.

Student Scholarship & Creative Works

Through the utilization of Light Detection and Ranging data, one can compile 3-dimensional models that can be used to spot anomalies of historical interest. These anomalies, if recognizable by the trained eye, can then be used to geo-reference historic maps to gain a better understanding of historic sites as well as to reveal possible areas of interests or unknown features.

By using a 3-dimensional model compiled by LiDAR data, I was able to geo-reference a December 13^th, 1861 map of the Civil War defenses for the town of Smithland, Kentucky. Through this process, I have been able to …

Economic Resilience And Concentration In Indiana Over 2002-2016, Santiago Ruiz, Michael Wilcox, Indraneel Kumar

Purdue GIS Day

It is well accepted that recessionary shocks affect long-term patterns of economic growth within regions. For this reason, it is important to understand how regional economies recover and in which extent a shock could be an economic burden in long term. A relevant variable to measure shock’s impact is employment, for two reasons. First, past recessions suggested that in most cases, the decline in employment tended to be deeper than in output. Second, layoffs of workers are key forms of adjustment to which employees seek to reduce costs. Given these, our research aims to understand shifts in employees during, after …

Gis To Address Questions In Forest Ecology And Management, Nicolas Picard

Purdue GIS Day

Geographic Information Systems (GIS) are powerful tools to deal with spatialized issues. As such, they have become routine tools in forestry to delimit forest resources, support the design of forest inventories, map forest resources, and analyze, model and support decision making to sustainably manage forests. Two examples will be provided to show how forest management can benefit from progress in GIS technology. The first one deals with the optimization of forest roads to harvest trees in tropical rainforests. It required the development of heuristics to solve the multiple target access problem in a reasonable time. The second one deals with …
