Estimation Of Aerosolized Antibiotic Resistant Bacteria Concentrations From Wastewater Treatment Facilities Using Spatially-Based Dispersion Modeling, Renee Nichole Dickman

Theses and Dissertations

Pathogenic bacteria can develop resistance to antibiotics to which they were previously sensitive, resulting in increased morbidity and mortality worldwide [1]. The increase in drug resistance in bacteria is an emerging public health concern. The activated sludge tanks of wastewater treatment plants are known sources of antibiotic resistant bacteria. These resistant bacteria can become aerosolized and disperse downwind. Using previously sampled aerosol concentrations and meteorological data, a Gaussian dispersion model was developed to estimate the concentration downwind from a selected wastewater treatment facility. The emission rate was calculated to be 7,941 CFU/m²/sec ± 2,149 CFU/m²/sec. This value was used in …

Urban Growth Patterns And Effectiveness Of The Metropolitan Urban Service Areas In Woodbury, Minnesota, Danielle Thomas

All Graduate Theses, Dissertations, and Other Capstone Projects

This study evaluates the effectiveness of a specific urban sprawl containment strategy called the Metropolitan Urban Service Areas (MUSA). MUSA was developed for Minneapolis/St. Paul in order to ensure organized and practical development in areas that already had pre-built roads and sewer system infrastructures. Currently, MUSA is not an urban boundary; its specific goal is to, "synchronize urban growth with the provision of infrastructure needed to accommodate growth" (Council, August 2006). To evaluate the rigidity of the MUSA boundaries, the sample years of 1990, 2000, 2010 and the projected 2020 boundaries were subjected to spatial analysis utilizing three different software …

From Mounds To Maps To Models: Visualizing Ancient Architecture Across Landscapes, Heather Richards-Rissetto

Department of Anthropology: Faculty Publications

Since the onset of settlement pattern studies in the 1950s, landscape mapping projects have become an archaeological mainstay. Remote sensing technologies such as lidar, photogrammetry, and SAR (Synthetic Aperture Radar) steadily reveal new archaeological sites. For landscape archaeology, the detection and mapping of small architectural complexes and households offers important data to contextualize larger (often already known) sites and perform regional analyses. However, because the majority of sites remain unexcavated, analysis is limited, and yet Geographic Information Systems (GIS) and 3D Visualization are expanding the possible uses for older and newly-acquired data on unexcavated mounds. This paper describes a GIS …

Inventory Of Mongolian Glaciers For The Global Land Ice Measurements From Space (Glims) Program, Caleb Gikai Pan

Graduate Student Theses, Dissertations, & Professional Papers

Glaciers in the Altai Mountains of Mongolia provide an estimated 10 % of the total water resources within the country. Yet, the number and area of glaciers within the Altai Mountains is inconsistent and conflicting. Glacier mapping attempts by previous author groups did not mention their mapping methods, data source, and/or date of analysis. Therefore, making it difficult to analyze and compare glacier base data. Due to a combination of climate change and land use management practices, the necessity of inventorying glaciers in the Altai Mountains of Mongolia is of great importance. The practice of glacier monitoring using remote sensing …

Joint Utility Of Event- Dependent And Environmental Crime Analysis Techniques For Violent Crime Forecasting, Joel M. Caplan, Leslie W. Kennedy, Eric L. Piza

Publications and Research

Violent crime incidents occurring in Irvington, New Jersey, in 2007 and 2008 are used to assess the joint analytical capabilities of point pattern analysis, hotspot mapping, near-repeat analysis, and risk terrain modeling. One approach to crime analysis suggests that the best way to predict future crime occurrence is to use past behavior, such as actual incidents or collections of incidents, as indicators of future behavior. An alternative approach is to consider the environment in which crimes occur and identify features of the landscape that would be conducive to crime. Thanks to advances in geographic information system technology and federally funded …

Ecological Diversity In Hillsborough County, Florida: Correlations Between Landscape Metrics And Socio-Demographic Variables, David Godfrey

USF Tampa Graduate Theses and Dissertations

Landscape metrics, a means of quantifying landscape attributes, are frequently used in landscape ecology to describe the spatial characteristics of a landscape, but they have been less often used in anthropology. Using geographic information system (GIS) software, this study tests a method that investigates statistical correlations between groundcover landscape metrics and socio-demographic variables in Hillsborough County, Florida. Statistically significant correlations were found, illustrating the potential utility of this exploratory method. Wealthier areas with fewer ethnic minorities tend to be more fragmented and diverse in terms of groundcover; these areas also tend to have a lower percentage of impervious surfaces. The …

Integrating Expert System And Geographic Information System For Spatial Decision Making, Sriharsha Shesham

Masters Theses & Specialist Projects

Spatial decision making is a process of providing an effective solution for a problem that encompasses semi-structured spatial data. It is a challenging task which involves various factors to consider. For example, in order to build a new industry, an appropriate site must be selected for which several factors have to be taken into consideration. Some of the factors, which can affect the decision in this particular case, are air pollution, noise pollution, and distance from living areas, which makes the decision difficult. The geographic information systems (GIS) and the expert systems (ES) have many advantages in solving problems in …

Agriculture, Influence, And Instability Under The Ancien Régime: 1708-1768, Adam J. Polk

Masters Theses

The French Revolution has been studied from myriad perspectives. The majority of scholarship focuses on the political and urban chaos of the times. Agricultural conditions and the influence of onerous taxation and stagnant agricultural options are given only a cursory examination in most research.

Using Biophysical Geospatial And Remotely Sensed Data To Classify Ecological Sites And States, Carson A. Stam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Within the Intermountain West, vast expanses of big sagebrush shrubland and steppe are considered emblems of the western range. Currently, there are approximately 60 million hectares of big sagebrush within the 11 western states, four million of which are in the state of Utah. However, the historic distribution of sagebrush has been impacted by conversion to other types of land cover through juniper encroachment, urbanization, invasive weeds, and agricultural expansion. In Utah alone, big sagebrush communities have been reduced to approximately 55% of their historic extent. A primary and current example of the cumulative impact of big sagebrush loss is …

Toward Renewable Eenergy Geo-Information Infrastructures: Applications Of Giscience And Remote Sensing That Build Institutional Capacity, K. Calvert, Joshua M. Pearce, W. E. Mabee

Department of Materials Science and Engineering Publications

Sustained policy support is necessary in order to drive a transition toward renewable energy (RE). The ability to realize RE policy objectives is constrained by a range of geographic factors related to resource potential, the distribution of resources, land availability/suitability, the absorptive capacity of proximal infrastructure, and local socio-political acceptance. With this in mind, this paper provides a systematic review of how geographic information science and remote sensing techniques have been applied to reduce uncertainties surrounding renewable energy development, with emphasis on policy and planning needs. The concept of a ‘geo-information infrastructure’ is used to bring coherence and direction to …

Water Resources Systems Planning And Management, Piro Zoga, Aida Bode, Ramiz Balla, Nevton Kodhelaj, Spartak Kucaj

UBT International Conference

The most fundamental human needs of water are for drinking, cooking and personal hygiene. In order to fulfill these needs, the quality of the water used should cause no risk to human health. The quality of the water in nature also affects the condition of ecosystems all living organisms depend on. At the same time, humans use water bodies as convenient sinks for the disposal of domestic, industrial and agricultural wastewaters. This, of course, degrades the quality of those water bodies. Water resources management involves the monitoring and management of water quality as much as the monitoring and management of …

The nutrition environment is one key influence and its relationship with food choice, behaviors, and socioeconomic influences is complex. Within the structure of the nutrition environment, food access and socioeconomic status compound influencing nutrition behavior and food choice.

Food deserts are defined as geographic region of low access to healthy affordable food in low income areas. The USDA developed a system for the …

Using Children’S Maps To Locate Areas Of Perceived Danger On Children’S Routes To School, Frank Bondzio, Ken Boyle

Conference Papers

Municipals and local authorities all over the world are attempting to boost the number of children walking or cycling to school as the benefits for children and society as a whole deriving from an active travel to and from school are widely acknowledged. For this reason programs that encourage active travel to school are often implemented by local authorities or schools. Many of these programs focus on the child. Cycle training or motivation programs aimed at a mode shift towards active travel are relatively easy to set up and can lead to quick results. Yet, a child centred review of …

Planning For Gentrification: A Geographic Analysis Of Gentrification Susceptibility In The City Of Asheville, N.C., Nakisha Fouch

All Theses

The American urban backdrop has seen an ebb and flow of investment and abandonment in the central city. The movement of the population from city to suburb and vice versa is often associated with access to lower rents, but is also driven by consumer demand. As redevelopment occurs in the once declining urban areas, economic development brings in a new middle class and the private and public services necessary to accommodate them. Inevitably, as new people move in current residents may be forced out. Addressing this issue is complicated by understanding what makes a neighborhood or a particular population prone …

A Multi-Scale Approach For Characterizing Habitat Selection Of Tidal Creek Fish In Charlotte Harbor, Florida, Renee M. Duffey

USF St. Petersburg campus Master's Theses (Graduate)

Fish abundance and diversity were calculated from fish catch data collected by Mote Marine Laboratory from 2005 through 2009. Twenty-three habitat variables were derived from data collected during field surveys and via GIS analyses. Field sampling methodology was adapted from the MesoHABSIM approach to delineate eleven habitat types at the …

Creation Of A Spatial Decision Support System As A Risk Assessment Tool Based On Kentucky Tornado Climatology, Christopher Michael Blinn

Masters Theses & Specialist Projects

Tornadoes are one of Mother Nature’s deadliest phenomena. They affect a large region of the United States. The risk of tornadoes is contingent on dynamic atmospheric conditions that are most likely during spring but which can occur anytime of the year, making the storms challenging to forecast. Using geographical information systems (GIS), a web-based spatial decision support system (SDSS) was created to help understand the spatial dimension of tornado risk assessment. The risk values are calculated using Tornado Days rather than taking a crude density measurement. The SDSS hosts GIS web services that are displayed on an Adobe Flex application. …

An Integrated Approach For Developing Adaptation Strategies In Climate Planning: A Case Study Of Vulnerability In Dukes County, Massachusetts, Jonathan Pollak

Master's Theses

Climate Action Plans (CAP’s) are recent innovations in policy that have been catalyzed by a need to adjust the relationship between human activity and the Earth’s climate system. CAP’s often are composed of methods to mitigate greenhouse gas emissions in addition to adaptation strategies. Research indicates, however, that many plans focus on mitigation strategies while adaptation policies related to predicted changes caused by climate change are often overlooked. This thesis presents an integrative framework for locating areas that are in need of adaptation strategies through a GIS based decision support system that visualizes vulnerability. It is operationalized through an empirical …

Mapping Women's Movement In Medieval England, Claire Clement

Theses and Dissertations

This thesis investigates women’s geographical movement in medieval England from the perspective of mobility and freedom. It uses pilgrimage accounts from medieval miracle story collections and to gather information about individual travel patterns. The study uses GIS to analyze gendered mobility patterns, and to investigate whether there were noticeable differences in the distance which men and women traveled and the geographical area of the country they originated. It also analyzes the nearness of men’s and women’s respective origin towns to alternative pilgrimage locations, as a means of examining the factors determining gendered travel mobility. The study finds that women’s travel …

The Role Of Human Awareness On The Spatial Patterns Of The Tick-Borne Disease Human Monocytic Ehrlichiosis In Missouri., James Edward Nunn 1985-

Electronic Theses and Dissertations

Human monocytic ehrlichiosis (HME), a tick-borne disease that has recently surfaced in the United States, exists in regions where the tick vector population is established. This study utilizes methods that look beyond identifying high-risk regions, and investigates disparate awareness, self-perceived threat, and seriousness of HME to further enhance existing spatial modeling. The Health Belief Model provides a theoretical framework that encompasses the disease ecology aspect of medical geography to understand the relationship between people and their environment by surveying participants in study regions of Missouri. Results are suggestive that awareness differs between high/low incidence regions. Furthermore, education and income were …

Using A Statistical Model To Locate Orthodontic Underserved Areas Capable Of Supporting Practices In Kentucky., Wes Cardall

Electronic Theses and Dissertations

Background: Malocclusion can affect an individual's quality of life. Unfortunately, access to orthodontic treatment is limited for many children. Access is improved when orthodontists select practice locations where their services are most needed. Methods: A statistical model was applied to demographic and dental practice data in Kentucky to determine underserved areas that have the capacity to support additional orthodontic practices. All zip codes and practices were mapped using a geographic information system (GIS). Results: The model identified 30 underserved zip codes with practice-supporting capability, but this number fell to zero after additional verification. Sixteen counties (13.3%) contain areas located more …

Prehistoric Foraging Strategies In The Piute Valley Of Southern Nevada, Christopher Alan Brosman

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Piute Valley of Southern Nevada is an incredibly diverse but arid zone in the eastern portion of the Mojave Desert. Most of this diversity can be attributed to the elevation shifts ranging from the Colorado River basin to the peaks of the surrounding mountain ranges. These peaks and valleys provide a multitude of resource zones in which prehistoric hunter-gatherers could provision themselves throughout the year. For this thesis I have used archaeological survey, paleo-climate models, life-sciences data and ethnographic research to perform an in-depth land use analysis of prehistoric forager adaptations to this challenging but life-sustaining environment.

Gis Collaborations In Saskatchewan: Sgic And The University Of Saskatchewan Library (Accepted Manuscript Version), Jasmine R. Hoover

Library Research and Publications

GIS (Geographic Information System) libraries face challenges at both ends of the spectrum when it comes to acquiring GIS data. On one hand, the increase in popularity of GIS driven by services like Google Earth, Bing maps, and open data has made large amounts of GIS data freely available to users. On the other hand, specialty GIS data products, often needed by researchers, industry, and government, can be so costly that they are impossible for a library to purchase on its own. In situations like the latter, collaborations often provide the solution for acquiring the necessary GIS data. This report …

Carbon Management And Scenario Planning At The Landscape Scale With Gis, Shabnam Delfan Azari

School of Geography, Earth and Environmental Sciences Theses

Carbon Management and Scenario Planning at the Landscape Scale with GIS By: Shabnam Delfan Azari It is now widely believed that globally averaged temperatures will rise significantly over the next 100 years as a result of increasing atmospheric concentrations of greenhouse gases (GHG) such as carbon dioxide. Responses to the threat of future climate change are both adaptations to new climate conditions, and mitigation of the magnitude of change. Mitigation can be achieved both through reducing emissions of greenhouse gases and by increasing storage of carbon in the earth system. In particular it is thought that there is potential for …
