Using Geographic Information Systems To Assess Risk For Elevated Blood Lead Levels In Children In Kalamazoo County, Michigan, Amatun Noor

Masters Theses

Lead-based paint is the major source of childhood lead poisoning for children under six in the United States and was commonly used in pre-1950 homes. The main objective of this study for Kalamazoo County, Michigan is to identify risk homes to for public health workers, and determine common socioeconomic factors from the US Census that can be used to identify relative risk across census tracts. A Geographic Information System (GIS) is applied to locate the risk homes of 485 children provided at the aggregate level by the Michigan Department of Community Health. Independent variables were derived from the U.S. 2000 …

The Relationship Between Landcover And Cloud-To-Ground Lightning Strikes In Kalamazoo, County, Michigan, Zachary J. Newton

Masters Theses

Lightning strike point data, collected by the National Lightning Detection Network™ in June, July, and August of 1993, was used in conjunction with geographic information systems (GIS) to examine the distribution of lightning strikes within and among landcover and geologic classes in Kalamazoo County, Michigan.

Quadrat analysis results showed that the lightning strike pattern did not follow a random distribution and exhibited a tendency for clustering when mapped with kernel density. A chi-square analysis showed there was a statistically significant relationship among landcovers, geology, and lightning strikes. Two t-tests were used to evaluate the data, one that corrected for location …

Analysis Of Factors Affecting Zebra Mussel (Dreissena Polymorpha) Abundance In Gull Lake, Michigan, Ryan P. Miller

Masters Theses

Zebra mussel (Dreissena polymorpha) proliferation has become a serious problem in the Great Lakes Basin. This study uses bathymetry, vegetation distribution, and substratum data to assess their relationship with zebra mussel measurements in Gull Lake, Michigan. Different statistical tests were performed in order to investigate the relationship between the variables and to infer any significance among the variables in relation to zebra mussel abundance. Dreissena polymorpha data include 16 sites on Gull Lake, collected in July of 1999. Vegetation, substratum, and bathymetric datasets were obtained and analyzed by using Geographic Information Science (GIS) techniques.

Trazando Fronteras, Persiguiendo Sueños: La Realidad De La Migración Del Campo En Nicaragua Hacia Costa Rica, Becca Telzak

Independent Study Project (ISP) Collection

“Este viaje en búsqueda de una mejor vida es lo que llamaremos migración y a sus pasajeros trabajadores migrantes.”

Durante este proyecto, yo escuché muchas veces las palabras Trabajadores Migrantes. Pero quien es un trabajador migrante? Según la organización ATC (asociación de Trabajadores del Campo del Nicaragua), “toda persona que se traslade de un país a otro para buscar empleo, trabaja o que haya realizado una actividad laboral remunerada.” Hay muchos tipos de trabadores que son migrantes: temporal, Semi permanente o permanente. Los trabajadores temporales son por un año o menos y trabajan durante las cosechas para exportación y dependen …

Quantifying Chlorophyll A Content Through Remote Sensing: A Pilot Study Of Utah Lake, Tiana Davis

Theses and Dissertations

Utah Lake is a really large but shallow lake located in the arid environment of the Western United States. Due to a variety of factors it is listed by the Environmental Protection Agency as an "impaired water body" and must be closely monitored. Because of its large extent and shallow depth the water quality is heterogeneous and can change rapidly. This means that traditional water quality monitoring methods, which require large investments in field personnel, equipment, and water sample analysis, cannot produce a model that is truly representative of the entire water body. This thesis examines the feasibility of using …

Terrain And Spatial Effects On Hazard Prediction And Assessment Capability (Hpac) Software Dose-Rate Contour Plot Predictions As Compared To A Sample Of Local Fallout Data From Test Detonations In The Continental United States, 1945-1962, Kevin D. Pace

Theses and Dissertations

Hazard Prediction and Capability (HPAC) Software is validated by comparing modeled predictions to historical test data. Reanalysis weather data is acquired and reformatted for use in HPAC. Simulations are made using various amounts of weather data by use of a spatial domain. Simulations are also varied by levels of terrain resolution. The predicted output of the software is numerically compared to historical test data. The result of this research culminated in the knowledge that HPAC prediction accuracy is improved by using terrain resolutions beyond the flat earth assumption. Furthermore, this research establishes that domain size variation produces no significant advantage …

Key objectives were to: 1. identify factors that have a significant effect on mountain climbing frequency; 2. collect information from physical trail and route evaluation to develop an interim classification index; 3. combine relevant variables to formulate a composite Fourteeners Environmental Degradation Index (FEDI) and use it to evaluate, rank, and compare …

Accuracy Assessment Of Land Cover Maps Derived From Multiple Data Sources, Daniel Unger, Hillary Tribby, Hans Michael Williams, I-Kuai Hung

Faculty Publications

Maximum Likelihood (ML) and Artificial Neural Network (ANN) supervised classification methods were used to demarcate land cover types within IKONOS and Landsat ETM+ imagery. Three additional data sources were integrated into the classification process: Canopy Height Model (CHM), Digital Terrain Model (DTM) and Thermal data. Both the CHM and DTM were derived from multiple return small footprint LIDAR. Forty maps were created and assessed for overall map accuracy, user's accuracy, producer's accuracy, kappa statistic and Z statistic using classification schemes from U.S.G.S. 1976 levels 1 and 2 and T.G.l.C. 1999 levels 2 and 4. Results for overall accuracy of land …

Indigenous Research: Whose Priority? Journeys And Possibilities Of Cross-Cultural Research In Geography, Paul Hodge, John Lester

Aboriginal Policy Research Consortium International (APRCi)

Decolonising research in geography is part of a broader ‘reflexive’ process which continues to question the positivist status of ‘researcher as observer’. This paper contributes to this reflexive turn, drawing on the particular experiences of a cross- cultural Honours thesis. The paper is pursued through a parallel journey involving a non-Indigenous researcher (and author of the cross-cultural Honours thesis) engaging Indigenous research1 with interpretative insight from an Indigenous adviser or ‘on-looker’. The methodological difficulties revealed by the parallel journey are emphasised to highlight both the complexities and reflexive possi- bilities of cross-cultural research but also to consider potential institutional and …

An Estimation Theory Approach To Detection And Ranging Of Obscured Targets In 3-D Ladar Data, Charles R. Burris

Theses and Dissertations

The purpose of this research is to develop an algorithm to detect obscured images in 3-D LADAR data. The real data used for this research was gathered using a FLASH LADAR system under development at AFRL/SNJM. The system transmits light with a wavelength of 1.55 micrometers and produces 20 128 X 128 temporally resolved images from the return pulse separated by less than 2 nanoseconds in time. New algorithms for estimating the range to a target in 3-D FLASH LADAR data were developed. Results from processing real data are presented and compared to the traditional correlation receiver for extracting ranges …

Bda Enhancement Methodology Using Situational Parameter Adjustments, Michael V. Carras Jr.

Theses and Dissertations

In the context of close ground combat, the perception of Battle Damage Assessment (BDA) is closely linked with a soldier’s engagement decisions and has significant effects on the battlefield. Perceived BDA is also one of the most complex and uncertain processes facing the soldier in live combat. As a result, the modeling and simulation community has yet to adequately model the perceived BDA process in combat models. This research effort examines the BDA process from a perception standpoint and proposes a methodology to collect the pertinent data and model this perception in the Army’s current force-on-force model, CASTFOREM. A subject …

Regeneration Patterns And Facilitation Following Blowdown In A Self- Replacing Lodgepole Pine (Pinus Contorta) Stand In Central Oregon, Jennifer Michelle Karps

Dissertations and Theses

Nurse plant and object facilitation is an important factor mitigating abiotic stress, improving seedling recruitment, and shaping the fine-scale spatial patterns of many plant communities. I investigate the role of facilitation on lodgepole pine regeneration following blowdown in central Oregon. My objective is to examine the importance of nurse objects on seedling recruitment under varying stand conditions. I base my analysis on 1) the mapped locations and attributes of seedlings, saplings, trees, shrubs, snags, stumps, and sound and decomposed logs in each of five, 500 m² circular plots, 2) water holding capacity estimates of woody and leafy litter and …

Music And Moral Geographies: Constructions Of "Nation" And Identity In Singapore, Lily Kong

Research Collection School of Social Sciences

In this paper, I attempt to pull together sociological and geographical perspectives in the study of music to understand the ways in which pop and rock music are socio-cultural products with political and moral meanings and implications. I examine state engineering of moral panics, focusing on a case study of pop and rock music in post-independence Singapore. Such engineering is aimed at political and ideological ends, in particular, "nation"- building outcomes. In engineering moral panics through both discursive and legislative acts, the contours of a moral geography are delineated at various spatial scales. First, at the scale of the national …

Deer-Vehicle Accident Hotspots In Northwest Clackamas County, Oregon, Linda K. Anderson

Dissertations and Theses

Road-kill of wildlife is common on Portland, Oregon's suburban fringe where development has increased road densities and traffic volume in rural areas. I identify the spatial and temporal patterns of black-tailed deer (Odocoileus hemionus columbianus) deer-vehicle accidents (DVA) at the suburban/rural interface of developing northwest Clackamas County using deer carcass pickup reports for county maintained roads for 1997-2004 and Oregon Department of Transportation deer-vehicle accident reports for 1996-2004. No black-tailed deer DVA models exist in the literature.

DVA increased 121% from 1997 to 1999 followed by a 26% decline by 2004. The initial DVA increase appears related to …

Monitoring Surface Displacement Of The Colby Green Retaining Pond Dams, John Goss

Undergraduate Research Symposium (UGRS)

The Colby Green is a campus expansion project which began in October of 2003. The construction would result in three new buildings, additional parking, and an elliptical 75,000-squarefoot green southeast of Mayflower Hill Drive. There were also plans for the construction of three run-off management and sediment ponds below the green, to manage flooding of the green. Three drains in the green transport water to the three retaining ponds which slowly disperse water into the surrounding environment. The ponds were created by constructing earthen dams around the drain outlets. The dams are composed of soil, cobbles, and boulders procured from …

Spatial Analysis Of Historic Cemeteries: Using High Spatial Resolution Imagery As A Visual Aid, Richard E. Brooks, Daniel Unger, I-Kuai Hung

Faculty Publications

Oak Grove Cemetery, located within the City of Nacogdoches in Nacogdoches County Texas, is one of the earliest cemeteries in the county dating to the early 1800’s. Several historic Texans are interred within this cemetery including Thomas J. Rusk and Charles S. Taylor who was the great-great-grandfather of current United States Senator Kay Bailey Hutchison. Due to a fire circa 1910 many of the records for the original section of the cemetery were lost. In the summer of 2006, the GPS coordinates of each grave marker within the cemetery were plotted on a backdrop of 6 inch spatial resolution multispectral …

The Use Of Relationship Marketing In Developing Network And Co-Operative Links Within Tourism Product Marketing Groups (Pmg’S, Catherine Gorman

Books / Book chapters

Co-operative marketing groups are common in tourism, particularly in the case of destination marketing. Destination tourism marketing groups offer a diverse range of tourism products and experiences which complement each other and are delineated by a specific geographical parameter. Tourism product marketing groups offer similar tourism products or services and through a co-operative approach focus on an identified target markets. Co-operative marketing can make greater impact in terms of market presence and can be more cost effective. Members need to see the value in their membership in order to remain involved. Many tourism product providers are SMTE’s (Small and Medium …

An Evaluation Of Two Gcms: Simulation Of North American Teleconnection Indices And Synoptic Phenomena, Justin T. Schoof, S C. Pryor

Publications

We evaluate the ability of two coupled atmospheric–oceanic GCMs – the Hadley Center’s third generation coupled climate model (HadCM3) and the Canadian Center for Climate Modeling and Analysis second-generation coupled model (CGCM2) – to simulate the North Atlantic Oscillation (NAO), the Pacific North American teleconnection pattern (PNA), and map patterns in the Midwest region of the United States, relative to NCEP/NCAR reanalysis (NNR) data. The observed (NNR-derived) and GCM-derived probability distributions and temporal behavior of the daily teleconnection indices exhibit agreement over the 1990–2001 reference period, and both GCMs successfully reproduce the range of 500-hPa map patterns over the study …

Holiday Home Owners, A Route To Sustainable Tourism Development? An Economic Analysis Of Tourist Expenditure Data, Ziene Mottiar

Articles

Although sustainability comprises economic social and environmental aspects, economic analysis has been less evident in this literature. This article takes an economic perspective to evaluate the contribution of holiday home owners to a local economy. Tourism destinations which are at the mature stages of the tourism lifecycle wish to maximise revenue from tourism while minimising costs such as overcrowding. A prime objective has to be to attract the more valuable tourists. The analysis of North Wexford in Ireland poses questions such as: How does the holiday home owners’ expenditure in the local area compare to that of traditional tourists? Do …

Settling the Maine Wilderness - Moses Greenleaf, His Maps, and His Household of Faith, 1777-1834.

Osher Library Associates, Occasional Publication No.3.

For professor Macdougall, this book is the culmination of over twenty-five years of research and writing carried out during breaks from teaching at the University of Maine. By examining the cultural milieu of his time, he places Greenleaf's contributions within the context of Maine's growth and development during its formative years from province to statehood. This biographer also shares a kinship with Greenleaf on several counts. First is an appreciation for the land which Greenleaf held dear, since his …

No. 1: Migration And Development In Africa: An Overview, Richard Black, Jonathan Crush, Sally Pederby, Savina Ammassari, Lyndsay Mclean Hilker, Shannon Mouillesseaux, Claire Pooley, Radha Rajkotia

Southern African Migration Programme

Migration is clearly a major issue across Africa. Indeed, migration – both within countries and across borders – can be seen as an integral part of labour markets and livelihoods across much of the continent for at least the last century. Over time, and in different places, migration has taken a number of different forms. It has cut across class and skill boundaries, and exists in widely different geographical and demographic contexts. Migration represents an important livelihood strategy for poor households seeking to diversify their sources of income, but is also characteristic of the better off, and indeed of many …

The Ethics Of Wildlife Control In Humanized Landscapes, John Hadidian, Camilla H. Fox, William S. Lynn

Ecology Collection

The 21st century is witness to an unprecedented and rapid growth of human settlements, from urban centers to wilderness vacation resorts. Concurrent with this has been the growing tolerance and acceptance of many wild animals and humans for one another. This has created an expanding ‘zone’ of human-animal contacts, some number of which invariably result in conflicts. While the vast majority of our interactions with wild animals are undoubtedly benign, it is the conflict between wildlife and people that draws particularly close attention from the public. Animals viewed as vertebrate “pests” range from the small to the large, the timid …

“Nuisance” Wildlife Control Trapping: Another Perspective, Brad Gates, John Hadidian, Laura Simon

Wildlife Population Management Collection

Urban wildlife control is a rapidly growing profession in which many practitioners apparently still come from a recreational or commercial trapping background. Perhaps for that reason, much of the “control” in resolving human-wildlife conflicts in cities and suburbs seems to revolve around the use of lethal traps to eliminate “problem” animals. Although some states allow relocation and most apparently allow for nuisance animals to be released on site, the extent to which these practices occur is little known. Further, the biological impacts of continual trapping cycles on urban wildlife populations remain little known as well. An alternative approach to trapping …

Sacred Space/Place, Paul Faulstich

Pitzer Faculty Publications and Research

Landscape, space, and place are three concepts that merge together to create the human experience of the environment. Space is the most basic concept of geography; it is the three-dimensional extent in which objects and events occur. Landscapes and places are both contained within space.

Ethnoecology, Paul Faulstich

Pitzer Faculty Publications and Research

Ethnoecology – the study of cultural explications of nature – generates insights into the interface between peoples and the more-than-human world. Ecology is the scientific study of the interrelationships between plants, animals, and the environment, and it has developed into the study of interdependent communities of organisms and their environments. But while most ecologists have been trained to seek knowledge solely from scholarly books or nonhuman nature, tremendous environmental information is stored in the minds, cultures, and arts of indigenous peoples.

Geophilia, Paul Faulstich

Pitzer Faculty Publications and Research

Extrapolated from E. O. Wilson's concept of biophilia, geophilia asserts that humans have an organic propensity to find wildlands emotionally compelling. It exists as a human tendency to emotionally connect with natural landscapes.

The Study Of Urban Form In Canada, Jason Gilliland, Pierre Gauthier

Geography & Environment Publications

This paper examines contributions to the study of urban form in Canada by French and English researchers working in a variety of disciplines, especially architecture, planning, geography, and history. Instead of discussing contributions purely along traditional linguistic or disciplinary lines, the authors use a novel classification scheme to identify and categorize significant works according to their particular epistemological perspective, before describing noteworthy contributions of various academic disciplines by key authors and research themes. The most significant contributions to the study of urban form in Canada have come from two largely isolated camps: first, architects/planners, mostly from Québec, who examine form …

Mapping Urban Morphology: A Classification Scheme For Interpreting Contributions To The Study Of Urban Form, Pierre Gauthier, Jason Gilliland

Geography & Environment Publications

Urban morphology is a thriving field of enquiry involving researchers from a wide diversity of disciplinary, linguistic and cultural backgrounds. While this diversity has helped advance our understanding of the complexity of urban form, confusion and controversy has also arisen over the various theoretical formulations forwarded by researchers from different philosophical and epistemological backgrounds. With the aim of improving intelligibility in the field, this paper proposes a straightforward scheme to identify, classify and interpret, or ‘map’, individual contributions to the study of urban form according to their respective theoretical or epistemological perspectives. Drawing upon epistemological discussions familiar to the readers …
