Expanding The Conceptual, Mathematical And Practical Methods For Map Comparison, Gilmore Robert Pontius, John Connors

Geography

Conventional methods of map comparison frequently produce unhelpful results for a variety of reasons. In particular, conventional methods usually analyze pixels at a single default scale and frequently insist that each pixel belongs to exactly one category. The purpose of this paper is to offer improved methods so that scientists can obtain more helpful results by performing multiple resolution analysis on pixels that belong simultaneously to several categories. This paper examines the fundamentals of map comparison beginning from the elementary comparison between two pixels that have partial membership to multiple categories. We examine the conceptual foundation of three methods to …

Freight Transport, Seamlessness, And Competitive Advantage In The Global Economy, Cristina Capineri, Thomas R. Leinbach

Geography Faculty Publications

Freight transport has emerged as one of the most critical and dynamic aspects of the transport sector where change has become the norm. It is now the main element supporting global commodity and more generally supply chains. Yet the lack of seamlessness and inefficiencies in general as well as the rising costs and complexities of shipping and delivering goods are adding to profit pressures faced by manufacturers across the globe. Our paper first discusses the concept of seamlessness, and then examines some of the consequences of the lack of seamlessness in terms of freight transport inefficiencies. We then begin to …

Coherent Structures And Aeolian Saltation, Jean Taylor Ellis

Faculty Publications

Aeolian sand transport models, widely employed by coastal scientists and managers, assume temporal and spatial homogeneity within the saltation field. This research questions that assumption by demonstrating that the saltation field is event-driven, therefore indicating that the saltation field is not temporally steady. The findings from this research may explain a portion of the conclusions from previous studies that indicated inequalities between model-estimated and field-measured aeolian sand transport. The relationship between unsteadiness in a turbulent wind field and pulses in a sand transport field was investigated on a beach near Shoalhaven Heads, New South Wales, Australia. Microphone-based saltation sensors, “miniphones,” …

Winds Of Change?: Projections Of Near-Surface Winds Under Climate Change Scenarios, S C. Pryor, Justin T. Schoof, R J. Barthelmie

Publications

Changes in near–surface wind speeds due to global climate change may have profound geophysical and societal impacts. However, Global Climate Models (GCMs) are unable to replicate the historically observed magnitude and spatial variability of wind speeds, so we apply a downscaling technique to generate probability distributions of wind speeds at sites in northern Europe for historical periods (1961–1990 and 1982–2000) and two future periods (2046–2065, 2081–2100). Projections for the twenty-first century (C21st) indicate no evidence of substantial evolution relative to the end of the twentieth century (C20th), although there is increased divergence of results from downscaling of different GCMs toward …

From The Pixels Up : Processes And Procedures In The Construction Of A Neural-Site Geographic Information System, Christopher John Mason

Master's Theses

This study examines the question, is it possible to develop a neutral-site Geographic Information System (GIS) that addresses information needs useful for the training of emergency management personnel? To answer this question a subordinate question requiring an answer is what specific steps are required to accomplish this goal? As a base for the data provided here, the history of cities as an initial root of civilization and the concept of emergency management are discussed. Direct intersections, where the specific applications of emergency management technology provide real benefits to local governmental organizations, such as those at the city level are also …

Topographies Of Home And Citizenship: Arab American Activists, Lynn A. Staeheli, Caroline R. Nagel

Faculty Publications

Home and citizenship carry contradictory and ambiguous meanings for immigrants as they negotiate lives ‘here’ and ‘there’. We use the concept of topography to analyze the ways in which activists in the Arab-American community draw connections between homes in the United States and in the Middle East. In intensive interviews, we ask activists about how their understanding of home influences their activism and positioning as citizens within the United States. Activists often bring to their work conceptualizations of home and citizenship that are open, and that connect home to broader forces operating at various scales and in more than one …

Monitoring The Relationship Between The Public And Public Lands: Application To Wilderness Stewardship In The U.S., Alan E. Watson, William T. Borrie

Society and Conservation Faculty Publications

Stakeholders in wilderness, and other public lands, have varying opinions on how well the land management agencies reflect their values and respond to their needs in management, and they therefore vary in their level of commitment and attachment to these places and the activities that occur there. Establishing baseline measures and monitoring indicators of the relationship between the public and wilderness lands can provide efficient evaluations of many management activities. Examples include protection of traditional relationships for indigenous people, and the enhancement and protection of relationships between the resource and both local and distant populations of stakeholders.

Oxygen Demand Trends, Land Cover Change, And Water Quality Management For An Urbanizing Oregon Watershed, Michael Karl Boeder

Dissertations and Theses

In-stream aquatic habitat depends on adequate levels of dissolved oxygen. Human alteration of the landscape has an extensive influence on the biogeochemical processes that drive oxygen cycling in streams. Historic datasets allow researchers to track trends in chemical parameters concomitant with urbanization, while land cover change analysis allows researchers to identify linkages between water quality trends and landscape change.

Using the Seasonal Kendall's test, I examined water quality trends in oxygen demand variables during the mid-1990s to 2003, for twelve sites in the Rock Creek sub-watershed of the Tualatin River, northwest Oregon. Significant trends occurred in each parameter. Dissolved oxygen …

Place, Sport And Globalization: Making Sense Of La Marca Barça, Hunter Shobe

Geography Faculty Publications and Presentations

The case of Football Club (FC) Barcelona provides a compelling case for
examining the impact of globalization on the place/identity role of football
clubs. FC Barcelona has deep historical connections to Barcelona and
Catalonia. These connections were de-emphasized by the clubs leadership
under Josep Lluís Núñez (1978-2000) and Joan Gaspart (2000-2003) and
promoted again by Joan Laporta and his directors (elected in 2003). At the
same time, under Laporta, FC Barcelona has developed into a successful
global brand. How are we to understand this renewed focus on the local and
national discourses of place while the team is simultaneously promoted …

Montavilla: Mapping Community Assets, Adrien Allred, Ann Shaw Lee, Chris Stahlberg, Eugene Nucci

Asset Mapping: Community Geography Project

In May of 2006, Southeast Uplift of Portland Oregon approached Portland State University Mapping Community Assets Senior Capstone class with a proposed project. They asked the class to explore the community connections and assets in southeast Portland, and, specifically in the Montavilla Neighborhood. They were interested in the community organizations that might exist in the area and the way these organizations interacted with each other and the community as a whole. The class goal was to come up with a tool that could be used in the other southeast neighborhoods based on the research and experience in Montavilla.

Lives, Livelihoods, And Landscapes: A Study Of Land Use And Social Change In Northeastern Nepal, Jennifer Leigh Anderson

Dissertations and Theses

This thesis explores the forces of change in lives and landscapes that have altered the Lamosangu-to-Everest route in northeastern Nepal and shows how a transect in photographs and conversations across the east-central Himalaya allows us insight and a greater understanding into the processes and consequences of this change.

Three forces of change over the last twenty-five years dominated discussions with local informants: the rise of the "People's War"-Nepal's Maoist Insurgency beginning in 1996; the Democratic Revolution of 1990; and dependence on tourism for livelihood after the establishment of Sagarmatha National Park in 1976. Understanding the cultural-historical context for these forces …

Urban Particulate Matter 2.5 Mass Concentrations: A Comparison Between A Drive-Through And A Park Setting, Cheryl Robertson

Theses and Dissertations (Comprehensive)

The focus of this thesis was to determine if light-duty vehicles idling at drive-throughs elevated ambient PM 2.5 mass more than those emitted by natural sources at a near-by greenspace. Two low-volume samplers (MiniVols), obtained from the Meteorological Services of Canada Air Quality Processes Research Division (ARQP), were set up 1.4 km apart in the west end of Kitchener, Ontario between the months of August and November, 2002. Four diurnal sampling periods were conducted on various days to determine when PM 2.5 mass concentrations were higher and at which location. Although overall results determined that the control site had obtained …

Assessment And Classification Of A Modified Urban Stream: Schneider Creek, Kitchener, Ontario, J. Andrew Carnegie

Theses and Dissertations (Comprehensive)

This study has produced an assessment framework and classification designed specifically for urban modified streams. While many stream assessment frameworks do exist, most are designed for natural streams and as such have no provision for characteristics of urban streams such as concrete channelization, storm drains, and urban debris. Building upon previous assessment and classification schemes, both urban and natural, this framework satisfies this need. It strengths lie in its user-friendly, visual-based approach to assessment by employing representative photographs and qualitative information to aid the user. A total of ten variables were employed that are scaled on a spectrum of categories, …

A History Of Non-Farm Rural Residential Development In Oxford County, Ontario And Its Impact On Farm Life, Jaime Lynne Patricia Gillespie

Theses and Dissertations (Comprehensive)

This paper traces the history of non-farm rural residential development in Oxford County, Ontario from the early 1970s through to 2004 and investigates the impact of these non-farm uses on farm activities. In contrast to planning departments in the Province of Ontario that have been slow to develop restrictions on non-farm development, Oxford Country has a long history of safeguarding its agricultural heritage through its planning policies. This paper examines the effectiveness of Oxford County’s legislation in preserving agricultural land and in preventing non-farm rural residential development. The literature review presents an overview of agriculture in southern Ontario, Ontario’s agricultural …

The Roles Of Digital Libraries In Teaching And Learning Geography, Chew-Hung Chang, John Hedberg, Tiong-Sa Teh, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Adopting a problem-centred approach helps students to learn Geography more effectively as they are able to identify and generalize about where different resources or activities are spatially located and they learn to associate certain patterns and processes with geographical changes. In an era where web-based student-centred inquiry is gaining popularity as a mode of learning Geography, the role of digital libraries as delivery trucks (in Clark’s terminology, 1983) needs to be better understood. An obvious affordance of the digital library is that it organizes information around themes for problems to be solved. This paper describes a developmental project to build …

Service-Learning In Watershed-Based Initiatives: Keys To Education For Sustainability In Geography?, James Eflin, Amy L. Sheaffer

Service Learning, General

A call for combining the strengths of geographic education with environmental education to produce an 'education for sustainability' addresses local problems for sustainable development. A place-based approach encourages civic responsibility among students. Using service-learning to extend education beyond the classroom in this case study connected students with local clients in a watershed-based initiative. Theoretical underpinnings of service-learning for geographic education are discussed, and the case study is viewed from instructor, student, and client perspectives to identify successful outcomes and provide suggestions for those who might adopt service-learning for the first time.

A Political Ecology Of The Chipko Movement, Sya Kedzior

University of Kentucky Master's Theses

The Indian Chipko movement is analyzed as a case study employing a geographically-informed political ecology approach. Political ecology as a framework for the study of environmental movements provides insight into the complex issues surrounding the structure of Indian society, with particular attention to its ecological and political dimensions. This framework, with its focus on social structure and ecology, is distinct from the more traditional approaches to the study of social movements, which tend to essentialize their purpose and membership, often by focusing on a single dimension of the movement and its context. Using Chipko as a case-study, the author demonstrates …

An Analysis Of Community Forest Implementation In British Columbia, Canada, Ryan C. Bullock

Theses and Dissertations (Comprehensive)

The community forest is increasingly seen as an alternative to industrial forestry for its perceived potential to mitigate conflict in forest resource management and planning. Theoretically, a community-based approach affords the chance to assert local values, provide local benefits, and manage resources differently than established top-down approaches. Yet practical examples of community forest initiatives in Canada reveal a host of constraints. This research uses a multiple case study design to investigate the motivations for and challenges to implementing community forests in British Columbia, Canada. Observations are drawn from four case studies (Denman Island, Malcolm Island, Cortes Island, and Creston) in …

Modelling Relationships Between Road Access And Recreational Fishing Site Choice While Accounting For Spatial Complexities, Lenny Michael Hunt

Theses and Dissertations (Comprehensive)

This study examined the relationships between road access and the fishing site choices of northern Ontario recreational anglers. A revealed preference choice model (random utility model) was estimated with fishing trip data from an angling diary with resident anglers from the Thunder Bay and Wawa areas. The results showed that poor quality gravel roads and trails heavily and negatively impacted fishing site choices by Thunder Bay anglers who fished only during the open water season. Poorer quality roads and trails had much less impact on the fishing site choices of other Thunder Bay anglers. Wawa area anglers were, on average, …

Spatial Autocorrelation Of Deer-Vehicle Accidents In Vigo County, J. Scott Horn

All-Inclusive List of Electronic Theses and Dissertations

Deer-vehicle accidents (DV As) are a problem in many areas. They cause millions of dollars in property damage, personal injury, and loss of life each year. This thesis examines whether DVAs in Vigo County, Indiana during the year 2000 were spatially autocorrelated; and whether DV As selected by deer habitat were spatially autocorrelated. Specifically using Moran's I to test for spatial autocorrelation this study determined if and to what degree spatial autocorrelation existed among these DVAs. A Moran's I value of .0023 shows that the accidents occurred randomly. These DV A data were then used to plot a map which …
