Gis-Integrated Mathematical Modeling Of Social Phenomena At Macro- And Micro- Levels—A Multivariate Geographically-Weighted Regression Model For Identifying Locations Vulnerable To Hosting Terrorist Safe-Houses: France As Case Study, Elyktra Eisman
FIU Electronic Theses and Dissertations
Adaptability and invisibility are hallmarks of modern terrorism, and keeping pace with its dynamic nature presents a serious challenge for societies throughout the world. Innovations in computer science have incorporated applied mathematics to develop a wide array of predictive models to support the variety of approaches to counterterrorism. Predictive models are usually designed to forecast the location of attacks. Although this may protect individual structures or locations, it does not reduce the threat—it merely changes the target. While predictive models dedicated to events or social relationships receive much attention where the mathematical and social science communities intersect, models dedicated to …
Applying Voronoi Tessellations As A Non-Orthogonal Grid Methodology To Inform Public-Private Mix Efforts In Nigeria: An Examination Of The Distribution Of Private Healthcare Providers In Six States And The Covariates Underlying Their Utilization, Trinadh Dontamsetti
USF Tampa Graduate Theses and Dissertations
TB care and prevention is led by the public sector, but many TB symptomatics first seek care in the private sector, highlighting the importance of engaging these facilities. This report examines basic TB epidemiology (such as the gap in case finding that could be addressed in part via private sector activities), health-seeking behaviors (HSB) and diagnostic delays, the size of the private sector, activities of professional societies, and financing. It examines the potential utility of integrating Voronoi tessellations as a GIS-based method for informing and improving Public-Private Mix (PPM) efforts throughout six states in Nigeria. Further, it explores a potential …

Estimating Medically Fragile Population Exposures To Tropical Storm Surges, James L. Wilson, Eileen Neuffer
Estimating Medically Fragile Population Exposures To Tropical Storm Surges, James L. Wilson, Eileen Neuffer
International Journal of Geospatial and Environmental Research
Background. A particularly vulnerable sub-population is the medically fragile. The medically fragile (MF) are defined as those who have at least one chronic condition and are electrically and pharmaceutically dependent, including the need for oxygen, and require care within 48 hours. Estimates of MF populations at risk from environmental hazards are important for emergency management planning and mitigation.
Materials and Methods. The MF population is comprised of 8% of the total population under 75 years plus all those 75+ years. Zonal estimates of MF populations are obtained by clipping block level US Census populations with SLOSH basin data (SLOSH Display …
Monitoring Invasive Plant Species: Summer Internship At Habitat Wildlife Sanctuary, Belmont, Massachusetts, Holly M. Zanoni
Monitoring Invasive Plant Species: Summer Internship At Habitat Wildlife Sanctuary, Belmont, Massachusetts, Holly M. Zanoni
International Development, Community and Environment (IDCE)
Habitat Wildlife Sanctuary, located in Belmont, Massachusetts is a dynamic suburban sanctuary that effectively upholds Mass Audubon’s three-part mission of advocacy, conservation, and education. Invasive plants threaten ecological integrity; however, proactive measures are taken to mitigate further encroachment. This is accomplished by surveying and taking inventory for presence of invasive species, then prioritizing them, and finally by incorporating high priority species into the immediate management strategy. Four invasive plants were formally analyzed using geographic information science during the 2014 growing season: Garlic mustard, Black swallowwort, Japanese knotweed, and Dame’s Rocket. The resulting density maps detected pattern changes from 2011, 2012, …
Alcohol Outlets, Social Disorganization, And Robberies: Accounting For Neighborhood Characteristics And Alcohol Outlet Types, Aleksandra J. Snowden, Tina L. Freiburger
Alcohol Outlets, Social Disorganization, And Robberies: Accounting For Neighborhood Characteristics And Alcohol Outlet Types, Aleksandra J. Snowden, Tina L. Freiburger
Social and Cultural Sciences Faculty Research and Publications
We estimated spatially lagged regression and spatial regime models to determine if the variation in total, on-premise, and off-premise alcohol outlet density is related to robbery density, while controlling for direct and moderating effects of social disorganization. Results suggest that the relationship between alcohol outlet density and robbery density is sensitive to the measurement of social disorganization levels. Total alcohol outlet density and off-premise alcohol outlet density were significantly associated with robbery density when social disorganization variables were included separately in the models. However, when social disorganization levels were captured as a four item index, only the association between off-premise …
Unisdr Scientific And Technical Advisory Group Case Studies 2015 | The Use Of Geographic Information Systems For Environmental Impact Assessments In Mine Action, Gianluca Maspoli, Angela Desantis
Unisdr Scientific And Technical Advisory Group Case Studies 2015 | The Use Of Geographic Information Systems For Environmental Impact Assessments In Mine Action, Gianluca Maspoli, Angela Desantis
Global CWD Repository
The 'do no harm' approach to mine action requires that mine action organisations consider the possible negative impacts of mine clearance operations. They must ensure they do not lead to longer-term vulnerability or threaten livelihoods and food security and, by mitigating environmental damage, they should contribute to disaster risk reduction. The combined use of remotely sensed data and Geographic Information Systems (GIS) can be a sound solution to assess pre-contamination conditions, monitor both the environmental impact and the effects of mitigation activities, analyse consequences of natural disasters on contamination, and, finally, support an evidence-based decision making process.
Visualizing The Historic Landscape Of Montserrat: Social Justice Through Community Mapping In A Post-Colonial Environment, Kevin Patrick Russell
Visualizing The Historic Landscape Of Montserrat: Social Justice Through Community Mapping In A Post-Colonial Environment, Kevin Patrick Russell
Masters Theses
Scholars across the disciplines of geography, archaeology, and history argue for need to reconceptualize representations of history in post-colonial environments and to actively orientate scholarly research towards increasing the inclusion of local knowledge with 'expert' academic knowledge through participative methods. This thesis will show that the landscape surrounding the Little Bay Plantation contains cultural associations vital to a "socially just" interpretation of Montserrat culture that is not captured by existing archaeological research centered on ruins of the plantation infrastructure and European historical discourse. Through a participatory research methodology this thesis shows that there are many memories inscribed within and upon …
Mapping Ancient Baldcypress Forests For Conservation At Black River, North Carolina, Jordan Nichole Burns
Mapping Ancient Baldcypress Forests For Conservation At Black River, North Carolina, Jordan Nichole Burns
Graduate Theses and Dissertations
A few ancient baldcypress-bottomland hardwood forests survive across the southeastern United States in a mosaic of remnant old-growth stands left untouched by extensive logging during the early 20th century. Uncut stands in the Southeast that survived centuries of disturbance following European settlement tended to be too senescent and non-commercial to justify logging. Remnant ancient baldcypress forests at Black River, North Carolina, appear to contain the oldest living trees in eastern North America and The Nature Conservancy has protected several of these stands. However, the full extent of ancient bottomland forests along Black River is not known and many valuable tracts …
A Study Of Colloquial Place Names Through Geotagged Social Media Data, Yuan Liu
A Study Of Colloquial Place Names Through Geotagged Social Media Data, Yuan Liu
Masters Theses
Place is a rich but vague geographic concept. Much work has been done to explore the collective understanding and perceived location of place. The last few decades have seen rapid expansion in the use of online social media and data sharing services, which provide a large amount of valuable data for research of colloquial place names. This study explored how geotagged social media data can be used to understand geographic place names, and delimit the perceived geographic extent of a place. The author proposes a probabilistic method to map the perceived geographic extent of a place using Kernel Density Estimation …

Rediscovery Of A Native American Cultural Landscape: The Chickasaw Homeland At Removal, Michael D. Walls
Rediscovery Of A Native American Cultural Landscape: The Chickasaw Homeland At Removal, Michael D. Walls
Theses and Dissertations--Geography
Little information beyond generalities exists regarding the cultural landscape of the Chickasaw Indians in their ancestral homelands prior to Removal in the late 1830s. This dissertation evaluates one possible archival source for specifics of Chickasaw land use, the field notes and survey plats compiled as part of the Public Land Survey System (PLSS). The process of original survey following land cession treaty divided the ceded area up into the familiar square-mile rectangular system of townships and ranges that extends from the Mississippi Territory westwards, in the so-called public land states.
The research compiles all cultural observations made by the surveyors …
Using Storm-Watersheds And A Multi-Criteria Decision Model For Biodiversity Conservation In An Urban Environment, Christina M. Chiappetta
Using Storm-Watersheds And A Multi-Criteria Decision Model For Biodiversity Conservation In An Urban Environment, Christina M. Chiappetta
Legacy Theses & Dissertations (2009 - 2024)
Many planning and land use decisions in New York State are controlled at the local (town or municipal) level, not an optimal scale for planning and implementing resource conservation management. Watershed boundaries provide a more ecologically meaningful scale for conservation, because they capture a full range of natural ecosystem processes that span political boundaries. However, defining an urban watershed is complicated by stormwater infrastructure, so standard topographic watershed boundaries may be inadequate for urban resource conservation even when applied at the watershed scale. Storm-watersheds distort both municipal and watershed boundaries, because the flows are redirected in ways that are often …

Recyclables collection is considered as a part of reverse logistics to which a specific routing problem is connected. Rise of recycling rate in recent years, and always high transportation costs are the main drivers for looking for the new methods how to optimize routing in residential recyclables collection. Geospatial relation of data by Geographic Information Systems (GIS) software can be used to design and analyze the routing strategy. In this Thesis ArcGIS and its Network Analyst extension is used to …
An Analysis Of Quality For Volunteered Geographic Information, Joel C H Meier
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 …
Essays On Sub-National Economic Growth: Evidence From A Global Sample, Dachao Ruan
Essays On Sub-National Economic Growth: Evidence From A Global Sample, Dachao Ruan
LSU Doctoral Dissertations
In this dissertation, I make three important contributions to the literature on regional economics. In Chapter 2, I construct a measure of early development, urban population density (urban population relative to total land area), that is novel to the growth literature, and apply GIS techniques to define and locate regions/cities and obtain geographic and historical measures across regions and cities. Chapter 3 investigates the persistence in sub-national development over the past 150 years. I find that regions that had a relatively higher urban population density in 1850 tend to be relatively more developed today. Geographic and climatic characteristics are significantly …
