Assessing The Needs And Guiding The Future: Findings From The Health Needs Assessment In 13 Asian American Communities Of Maryland In The United States, Sunmin Lee, Chiehwen Ed Hsu

Chiehwen Ed Hsu

There is lack of in depth data on health needs of diverse Asian American communities. We conducted 19 focus groups in 13 Asian American communities in Maryland in 2007. We developed a moderator’s guide to collect qualitative data on health needs from 174 participants, and used MAX QDA to analyze data and code emergent themes. Cardiovascular disease related conditions, diabetes, and mental health were the top three health concerns. Weight concerns, cancer, arthritis, smoking, osteoporosis, and hepatitis B followed next. Many participants were not receiving preventive health service such as cancer screening due to a lack of access to health …

The Analysis Of Agricultural Landscape Change Using Gis Techniques. Case Study: Podoleni, Romania, Dan A. Chelaru, Adrian Ursu, Florin C. Mihai

Florin C MIHAI

The increasingly tensions rising between society’s need for resources and space on the one hand, and the capacity of the land to support these needs on the other hand lead to unprecedented changes in landscape configuration, and hence, to the environment. This paper analyzes changes in the agricultural landscape of Podoleni, Neamt County, Romania, in spatio - temporal terms, as a result of the modernization of the ground processing techniques, types of crops, and the degree of fragmentation of land parcels. The study was conducted using Geographical Information Systems techniques, the main materials used in the analysis are topographic maps …

Geologic Constraints On Rain-Fed Qocha Reservoir Agricultural Infrastructure, Northern Lake Titicaca Basin, Peru, Nathan M. Craig, Mark Aldenderfer, Paul Baker, Catherine Rigsby, :Luis Flores Blanco

Nathan M Craig

This paper reports new data on qocha ponds from the Rio PucaraeAzángaro interfluvial zone, northern Lake Titicaca Basin, Peru. Qocha are a little known form of Andean agriculture that developed around 800e500 B.C. and remain in use today. Prior estimates suggested that in the study area, there were more than 25,000 qocha. While most Andean sunken beds are excavated to reach groundwater, qocha are rain- fed ponds. How these rain-fed ponds functioned has been an open question, but one that is answered in part by research presented in this paper.We suggest that a thick impermeable stratum of clay that was …


Ground Truthing Of Remotely Identified Fortifications On The Central Coast Of Perú, Margaret Brown Vega, Nathan M. Craig, Gerbert Asencios Lindo Jan 2011

Ground Truthing Of Remotely Identified Fortifications On The Central Coast Of Perú, Margaret Brown Vega, Nathan M. Craig, Gerbert Asencios Lindo

Nathan M Craig

Remote imagery, including freely available satellite images viewed in Google Earth_ and historic aerial photographs, was used to identify anomalies in a 25,000 km2 macroregion encompassing 13 river valleys along the Peruvian coast. These anomalies, located atop hills and mountains, were hypothesized prehispanic fortifications. A sample of remotely identified anomalies was ground truthed in the Huaura and Fortaleza Valleys on the Central Coast of Perú. 140 positive anomalies were documented and assessed using a simple defensibility index. Our results significantly increase the number of fortifications identified in both valleys. We demonstrate the efficacy of this method for locating fortifications in …


The Maritime Potential Of Asean Economies, Hans-Dieter Evers, Mhd Azhari-Karim Jan 2011

The Maritime Potential Of Asean Economies, Hans-Dieter Evers, Mhd Azhari-Karim

Hans-Dieter Evers

Countries may utilize a long coastline in relation to their landmass as a resource to develop their maritime conomy. This paper argues that ASEAN countries differ in utilizing their maritime potential. As a basis for further comparative studies the Center for Policy Research and International Studies (CenPRIS) in Penang developed a set of indicators to measure the maritime potential of nations, the state of their maritime industries, and the degree to which the maritime potential has actually been utilized. Using the CenPRIS Ocean Index (COI) shows that Brunei and the Philippines have underutilized their maritime potentials, whereas Singapore and Thailand …


Advancing Theory?: Landscape Archaeology And Geographical Information Systems, Di Hu Jan 2011

Advancing Theory?: Landscape Archaeology And Geographical Information Systems, Di Hu

Di Hu

This paper will focus on how Geographical Information Systems (GIS) have been applied in Landscape Archaeology from the late 1980s to the present. GIS, a tool for organising and analysing spatial information, has exploded in popularity, but we still lack a systematic overview of how it has contributed to archaeological theory, specifically Landscape Archaeology. This paper will examine whether and how GIS has advanced archaeological theory through a historical review of its application in archaeology.


A Meta-Analysis Of Global Urban Land Expansion, Karen C. Seto, Michail Fragkias, Burak Güneralp, Michael K. Reilly Jan 2011

A Meta-Analysis Of Global Urban Land Expansion, Karen C. Seto, Michail Fragkias, Burak Güneralp, Michael K. Reilly

Michail Fragkias

The conversion of Earth's land surface to urban uses is one of the most irreversible human impacts on the global biosphere. It drives the loss of farmland, affects local climate, fragments habitats, and threatens biodiversity. Here we present a meta-analysis of 326 studies that have used remotely sensed images to map urban land conversion. We report a worldwide observed increase in urban land area of 58,000 km2 from 1970 to 2000. India, China, and Africa have experienced the highest rates of urban land expansion, and the largest change in total urban extent has occurred in North America. Across all regions …

Theorizing Scale In Critical Place-Name Studies, Joshua Hagen Jan 2011

Theorizing Scale In Critical Place-Name Studies, Joshua Hagen

Geography Faculty Research

Building on broader developments in critical social theory, geographers have made significant strides in explicating the assumptions, motivations, and values involved in place naming. This has led to an emphasis on understanding the processes involved in the inscription, subversion, and revision of place names. Despite the increasingly sophisticated approaches found in place-name studies, the field of toponymy occupies a relatively minor position in academic geography. There are varied and complex reasons for this marginality, but perhaps the most salient critique is that place-name research has been slow to engage broader developments in geographic and social theory.

Gis Maps And The Amazon Borderlands, David S. Salisbury Jan 2011

Gis Maps And The Amazon Borderlands, David S. Salisbury

Geography and the Environment Faculty Publications

With training, GIS can be used by all sectors of Latin American society and is the mapping tool of choice for institutions ranging from the Inter-American Development Bank to remote communities in the Amazon rain forest. Geographic information systems are thus a tool of the powerful and the marginalized and the official and the unofficial. [...] In this chapter, we see how GIS maps can improve our ability to analyze conflict over resources and allow additional participation in the process of mapping, but we also confront some of the many political and technical challenges that must be overcome to construct …


A Parallel Computing Approach To Fast Geostatistical Areal Interpolation, Qingfeng Guan, Phaedon Kyriakidis, Michael Goodchild Jan 2011

A Parallel Computing Approach To Fast Geostatistical Areal Interpolation, Qingfeng Guan, Phaedon Kyriakidis, Michael Goodchild

Department of Geography: Faculty Publications

Areal interpolation is the procedure of using known attribute values at a set of (source) areal units to predict unknown attribute values at another set of (target) units. Geostatistical areal interpolation employs spatial prediction algorithms, i.e., variants of Kriging, which explicitly incorporate spatial autocorrelation and scale differences between source and target units in the interpolation endeavor. When all the available source measurements are used for interpolation, i.e., when a global search neighborhood is adopted, geostatistical areal interpolation is extremely computationally intensive. Interpolation in this case requires huge memory space and massive computing power, even with the dramatic improvement introduced by …


An Integrated Geographic Information Systems (Igis) Analysis And Definition Of The Tectonic Framework Of Northern Mexico, Carlos Manuel Martinez Jan 2011

An Integrated Geographic Information Systems (Igis) Analysis And Definition Of The Tectonic Framework Of Northern Mexico, Carlos Manuel Martinez

Open Access Theses & Dissertations

Crustal rupture structures reactivated in the course of the tectonic history of northern Mexico are the surface expressions of planes of weakness, in the form of simple or composite rectilinear features or slightly curved, defined as lineaments. Unless otherwise defined as strike-slip faults, lineaments are part of parallel and sub-parallel oblique convergent or oblique divergent tectonic zones cross cutting the Sierra Madre Occidental and northern Mexico, in a NW trend. These shear zones are the response to the oblique subduction of the Farallon plate beneath North America.

Kinematic analysis of five selected sites in northern Mexico, three basins and two …


Development Of A Web-Based Geographic Information System For Arctic Science, George Walker Johnson Jan 2011

Development Of A Web-Based Geographic Information System For Arctic Science, George Walker Johnson

Open Access Theses & Dissertations

Environmental science is a large field of study that requires the acquisition of data for decision making in solving environmental issues. Leveraging desktop geographic information systems (GIS) and web-based GIS (WebGIS) systems for assisting in the problem solving processes can benefit both the research community and policy makers for decision making activities. Ensuring interoperability between desktop, web, and server GIS is essential for maximizing access, sharing and manipulation of data. Interoperability is maximized through the adoption of best practices, use of open standards, and utilization of Spatial Data Infrastructures (SDI). While many of the interoperability challenges such as infrastructure, data …


Food Deserts' And 'Food Swamps' In Hillsborough County, Florida: Unequal Access To Supermarkets And Fast-Food Restaurants, Dana Beth Stein Jan 2011

Food Deserts' And 'Food Swamps' In Hillsborough County, Florida: Unequal Access To Supermarkets And Fast-Food Restaurants, Dana Beth Stein

USF Tampa Graduate Theses and Dissertations

Research has shown that the suburbanization of supermarkets has created `food deserts', defined as areas where socially disadvantaged individuals lack access to nutritious food outlets. Additionally, the growing presence of fast-food restaurants has created `food swamps', or areas where socially disadvantaged individuals encounter an overabundance of unhealthy food outlets. While previous studies have analyzed either `food deserts' or `food swamps' using conventional statistical techniques, a more comprehensive approach that includes samples of both healthy and unhealthy entities and considers the variety of available food options is necessary to improve our understanding of the local food environment and related disparities.

Road-Based Landscape Metrics For Quantifying Habitat Fragmentation, Rebecca Whitehead Loraamm Jan 2011

Road-Based Landscape Metrics For Quantifying Habitat Fragmentation, Rebecca Whitehead Loraamm

USF Tampa Graduate Theses and Dissertations

Landscape metrics measure the composition and configuration of habitats within landscapes; often the goal is to measure fragmentation. While a variety of existing metrics characterize the connectivity and contiguity of habitat patches, most do not explicitly consider the fragmenting effects of roads in their formulations. This research develops a set of new landscape metrics that explicitly quantify how roads disconnect and break apart habitat patches. This research introduces the following four metrics to consider the fragmenting effects of transportation networks: (1) Number of Connected Patches, a measure of connectivity; (2) Euclidean Nearest Neighbor-Roads, a measure of proximity; (3) Road Density, …

USF Tampa Graduate Theses and Dissertations

Pinellas County is located on a peninsula in Florida that experiences daily patterns of sea breeze associated rainfall mainly during the summer months of June through August. Previously, rainfall patterns, amounts and timing and severe weather in Pinellas County have not been examined considering dominant wind flow patterns, sea breeze circulations and other atmospheric variables. To improve forecasting of local mesoscale phenomena, this project examined the rainfall patterns, amounts and timing and severe weather occurrences that occur as a result of sea breezes and associated prevailing wind regimes within Pinellas County for the months of June, July and August for …


Determining Exurbia: Is It Really Its Own Entity Or Merely An Extension Of Americas Growing Suburbia, Thomas A. Green Jan 2011

Determining Exurbia: Is It Really Its Own Entity Or Merely An Extension Of Americas Growing Suburbia, Thomas A. Green

All Graduate Theses, Dissertations, and Other Capstone Projects

The purpose for studying exurbanization is to evaluate the spatial spread of metropolitan areas into their immediate hinterlands through remote sensing satellite imagery. This includes addressing scholar's inability to define exurbia, along with plausible reasons people move into exurbia. In addition, determination will include consideration on the possibility that exurbia has become an extension of America's growing and increasingly independent suburbia or; recognize that exurbia exists, but within various geographic locations. In return to the former, an analytical approach was taken to investigate scholar's inability to provide a definition to this phenomena; as well as inconsistent results on the push …


Minnesota River Basin Flood Mapping And Impact Assessment, Willy J. Mekeel Jan 2011

Minnesota River Basin Flood Mapping And Impact Assessment, Willy J. Mekeel

All Graduate Theses, Dissertations, and Other Capstone Projects

South Central Minnesota has experienced frequent flooding in the past because of the relatively flat topography, low elevation, and large amounts of snow melt in the spring. When these events happen, there is a large economic impact and potential health hazards to residents of the area. Having up-to-date flood zone maps can help residents be better prepared for emergency situations. Using Geographic Information Science (GIS), flood zone maps can be updated frequently in a more time efficient and inexpensive manner. Using a 30-meter digital elevation model (DEM) Compound Topographic Index (CTI) and Stream Power Index (SPI) layers were calculated for …
