Social Space And Social Media: Analyzing Urban Space With Big Data, Ate Poorthuis

Theses and Dissertations--Geography

This dissertation focuses on the key role that big data can play in minimizing the perceived disconnect between social theory and quantitative methods in the discipline of geography. It takes as its starting point the geographic concept of space, which is conceptualized very differently in social theory versus quantitative methodology. Contrary to this disparity, an examination of the disciplinary history reveals a number of historic precedents and potential pathways for a rapprochement, especially when combined with some of the new possibilities of big data. This dissertation also proposes solutions to two common barriers to the adoption of big data in …

Living On The Edge: Rethinking Pueblo Period: (Ad 700 – Ad 1225) Indigenous Settlement Patterns Within Grand Canyon National Park, Northern Arizona, Philip B. Mink Ii

Theses and Dissertations--Anthropology

This dissertation challenges traditional interpretations that indigenous groups who settled the Grand Canyon during the Pueblo Period (AD 700 -1225) relied heavily on maize to meet their subsistence needs. Instead they are viewed as dynamic ecosystem engineers who employed fire and natural plant succession to engage in a wild plant subsistence strategy that was supplemented to varying degrees by maize. By examining the relationship between archaeological sites and the natural environment throughout the Canyon, new settlement pattern models were developed. These models attempt to account for the spatial distribution of Virgin people, as represented by Virgin Gray Ware ceramics, Kayenta …

A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz

Graduate Student Theses, Dissertations, & Professional Papers

Chile's state designated protected areas are reported to show representation bias and to be unable to meet conservation goals. Private protected areas are considered an important tool to resolve these issues, which has led to support for increasing the role of private protected areas in Chile and creating an integrated public-private protected area network. But the validity of the capacity of private protected areas to fix Chile's state protected area network bias, and the advantage of creating an integrated protected area network, have not been assessed. This study uses the most recent data on Chile's state, private, and international protected …

The Economic Impacts Of Forest Pathogens In Washington State: A Hedonic Approach, Logan Blair

All Master's Theses

An increase in the incidence of forest pathogens in the Western US has created new resource management issues. In this research I employ a dataset of 170,141 housing transactions in twelve Western Washington counties to quantify the impacts of parasitic forest damage on the proxy real estate market. Specifically, I estimate a set of hedonic fixed effects models to control for omitted variable bias and spatial autocorrelation. Results show statistically significant impacts on property values in the presence of species specific and aggregate defoliation, suggesting new information for forestry management and policy.

Risk Terrain Modeling For Spatial Risk Assessment., Joel M. Caplan, Leslie W. Kennedy, Jeremy D. Barnum, Eric L. Piza

Publications and Research

Spatial factors can influence the seriousness and longevity of crime problems. Risk terrain modeling (RTM) identifies the spatial risks that come from features of a landscape and models how they colocate to create unique behavior settings for crime. The RTM process begins by testing a variety of factors thought to be geographically related to crime incidents. Valid factors are selected and then weighted to produce a final model that basically paints a picture of places where crime is statistically most likely to occur. This article addresses crime as the outcome event, but RTM can be applied to a variety of …

Towards A Theory Of Gis Program Management, Jochen Albrecht

Publications and Research

After a brief flurry of monographs on business and organizational aspects of GIS in the 1990s, little attention has been paid to a systematic approach in support of GIS Program management. Most existing efforts in both public and private enterprises are based on anecdotal evidence. This chapter outlines a range of research questions and the beginning efforts to study modern GIS management practices and help develop a body of knowledge that can be used for the accreditation of GIS Programs and the certification of GIS Program managers.

The Habitat Of European Brown Bears In Northern Spain: Mapping Habitat Fragmentation And Potential Connectivity, Alma D. Pacheco

Graduate Student Theses, Dissertations, & Professional Papers

The European brown bear in northern Spain is considered to be an endangered species whose habitat has been fragmented into two subpopulations due to habitat loss and lack of connectivity. The importance of improving connectivity and preventing more habitat destruction is vital to recover the species in this region. This research looks at spatial and temporal variations of brown bear habitat by mapping the conditions of habitat fragmentation and potential connectivity at a regional extent. This research examines net changes of brown bear habitat fragmentation between 1990-2000, 2000-2006, and overall 1990-2006; and the degree of brown bear habitat connectivity between …

A Migration Analysis Of Demographic Transitions In The Upper-Midwest From 2006-2010, Andrew Brick

All Graduate Theses, Dissertations, and Other Capstone Projects

Rural communities in the Upper-Midwest are essential for contributions to agriculture, oil and development of economic networks to larger towns and cities. Concerning rural population stability and transitions, this research study aims to discover complex migration flows by constructing specified groups of Upper-Midwest regions (i.e., Bakken oil, Taconite iron, high agriculture, developing area of rural depopulation and Interstate 94). Research questions on migrant distributions will be answered by investigating (in-) and (out-) flow data by demographic characteristics (e.g., age, gender and ethnicity) on a county-to-county level. By weighing total demographic populations, a more accurate representation of migration trends called Crude …

An Analysis Of Quality For Volunteered Geographic Information, Joel C H Meier

Theses and Dissertations (Comprehensive)

In recent years there has been a growing number of online user communities engaged in the creation, visualization, and use of volunteered geographic information (VGI). These data may represent an untapped resource for researchers analyzing large-area geographic phenomena such as species distributions patterns or land and resource management issues. However very few studies have used VGI for analytic research questions as little is known about the quality of these data. An understanding of the validity of VGI is a prerequisite for further exploitation of these novel data sources in research contexts. This paper looks to identify key issues related to …

Sacred And Mortuary Landscapes In Iron Age Cyprus: A Gis Analysis, James P. Torpy

Senior Independent Study Theses

During the Archaic period (750-480 BC) the island of Cyprus underwent a dramatic transformation as new city-kingdoms rose to dominate the political landscape of the island. This shift resulted in increased competition for resources, establishment of political boundaries, and emergence of a pronounced social hierarchy within the new polities. While many of the large settlements that became centers of power during this time have been thoroughly studied, the manifestation of the large scale changes of the Archaic in the periphery have not been as fully investigated. The rural site of Athienou-Malloura, surveyed and excavated by the Athienou Archaeological Project …

Patterns Of Consumption: Ceramic Residue Analysis At Liangchengzhen, Shandong, China, Rheta E. Lanehart

USF Tampa Graduate Theses and Dissertations

The purpose of this thesis was to identify the different patterns of food consumption across space and time at Liangchengzhen, a Longshan (ca. 2600-1900 B.C.) site located in Shandong Province, China. The primary hypothesis of the research contended that evidence of increasing social inequality with respect to food consumption would be found from early to late phases at Liangchengzhen. In addition, rice and meat from mammals, especially pigs, were hypothesized as the most likely types of prestigious foods for daily and ritual activities. Fish and marine foods in general were hypothesized to be foods that average households could obtain since …

Quantifying The Interaction Of Wildlife And Roads: A Habitat And Movement Approach, Rebecca Whitehead Loraamm

USF Tampa Graduate Theses and Dissertations

There is a growing need to address the effects of roadway presence on wildlife. Not only do roads directly impact gene dispersal from a movement perspective, but they limit movement of the individual animal from a habitat perspective by presenting an artificial barrier between one area of viable habitat and another. For this reason it is becoming increasingly important to quantify contact between humans and wildlife and to develop better methods for mitigating these types of conflicts. Studying habitat connectivity and animal mobility in the context of roads can provide actionable information on how, where, and when these encounters might …

Geo-Based Technologies, Tourists And Bushfires In Northern Australia, Donnell Holloway, David Holloway, Lelia Green

Research outputs 2014 to 2021

This paper analyses how the use of geo-based technologies can play a role in the safety of tourism operations and tourist travel — especially in the case of bushfires. The study uses data from 42 qualitative interviews with tourists, tourism operators and other stakeholders in the remote Kununurra area of Western Australia carried out in 2012 and 2013. We contend that the spatiotemporal nature of tourism has stimulated considerable development in a range of geo - based technologies. The paper argues that geo-based technologies are an integral part of fire suppression and mitigation practices, and that tourists’ familiarity with geo-based …

Land Surface Anomalies Preceding The 2010 Russian Heat Wave And A Link To The North Atlantic Oscillation, C. K. Wright, K. M. De Beurs, G. M. Henebry

Natural Resource Management Faculty Publications

The Eurasian wheat belt (EWB) spans a region across Eastern Ukraine, Southern Russia, and Northern Kazakhstan; accounting for nearly 15% of global wheat production. We assessed land surface conditions across the EWB during the early growing season (April–May–June; AMJ) leading up to the 2010 Russian heat wave, and over a longer-term period from 2000 to 2010. A substantial reduction in early season values of the normalized difference vegetation index occurred prior to the Russian heat wave, continuing a decadal decline in early season primary production in the region. In 2010, an anomalously cold winter followed by an abrupt shift to …

Of the different renewable energy technologies, wind energy is one of the most researched and implemented. Over the past twenty years, researchers have been applying Geographic Information Systems (GIS) to their climate change studies. GIS allows the user to spatially view, manipulate, and analyze data …

Improved Time Series Land Cover Classification By Missing-Observation-Adaptive Nonlinear Dimensionality Reduction, David P. Roy, L. Yan

GSCE Faculty Publications

Dimensionality reduction (DR) is a widely used technique to address the curse of dimensionality when high-dimensional remotely sensed data, such as multi-temporal or hyperspectral imagery, are analyzed. Nonlinear DR algorithms, also referred to as manifold learning algorithms, have been successfully applied to hyperspectral data and provide improved performance compared with linear DR algorithms. However, DR algorithms cannot handle missing data that are common in multi-temporal imagery. In this paper, the Laplacian Eigenmaps (LE) nonlinear DR algorithm was refined for application to multi-temporal satellite data with large proportions of missing data. Refined LE algorithms were applied to 52-week Landsat time series …

Station Exposure And Resulting Bias In Temperature Observations: A Comparison Of He Kentucky Mesonet And Asos Data, James Kyle Thompson

Masters Theses & Specialist Projects

Station siting, exposure, instrumentation, and time of observations influence longterm climatic records. This thesis compared and analyzed temperature data from four Kentucky Mesonet stations located in Fayette (LXGN), Franklin (LSML), Clark (WNCH), and Bullitt (CRMT) counties to two nearby Automated Surface Observation Systems (ASOS) stations in Kentucky. The ASOS stations are located at Louisville International Airport (Standiford Field - KSDF) and at Lexington Airport (Blue Grass Field - KLEX). The null hypothesis states that there is no significant difference in temperature measurements between the two types of stations. To quantify the differences in temperature measurements, geoprofiles and the following statistical …
