Futures Thinking For The Built And Human Environment: The Prospective Process Through Scenario Thinking For The Built And Human Environment: A Tool For Exploring Human Futures, John Ratcliffe, Lorcan Sirr Jan 2003

Futures Thinking For The Built And Human Environment: The Prospective Process Through Scenario Thinking For The Built And Human Environment: A Tool For Exploring Human Futures, John Ratcliffe, Lorcan Sirr

Articles

We are currently living through an era where we can, and need to, create exciting new possibilities in the way we think about, plan, design and build new places and spaces for working and living. At the same time, two irresistible forces – change and complexity – face decision-makers charged with framing and executing future policy and practice for the built and human environment. This paper generally argues the case for employing a ‘prospective’ process through scenario thinking for strategic planning and management in the urban arena. It does not attempt to identify or explore the advances made in planning …


Evaluation Of The Ncep/Ncar Reanalysis In Terms Of Synoptic Scale Phenomea: A Case Study From The Midwestern Usa, Justin T. Schoof, S C. Pryor Jan 2003

Evaluation Of The Ncep/Ncar Reanalysis In Terms Of Synoptic Scale Phenomea: A Case Study From The Midwestern Usa, Justin T. Schoof, S C. Pryor

Publications

We evaluate the ability of the National Centers for Environmental Prediction (NCEP)–National Center for Atmosphere Research (NCAR) reanalysis to represent the synoptic-scale climate of the Midwestern USA relative to radiosonde data. Independent, automated synoptic classifications, based on rotated principal component analysis (PCA) of 500 hPa geopotential heights, 850 hPa air temperatures, and 200 hPa wind speeds and a two-step clustering algorithm, result in a 15-type NCEP–NCAR synoptic classification and a 14-type radiosonde classification. The classifications are examined in terms of similarities and differences in the modes of variance manifest in the PCA solutions, the spatial patterns and variability of input …


Gis Modeling Of Desert Root Crop Maturation On The Mid-Columbia Plateau, Mary Michelle Phillips Jan 2003

Gis Modeling Of Desert Root Crop Maturation On The Mid-Columbia Plateau, Mary Michelle Phillips

All Master's Theses

The settlement patterns of the prehistoric inhabitants of the Columbia Plateau were choreographed to match the cadence of the seasons, with movements timed to efficiently utilize available resources. Desert roots, such as lomatium and bitterroot, provided a primary source of dietary nutrition, yet the ideal conditions for exploiting these plant resources coalesced for a very limited time in any one location. It was therefore necessary to possess an intimate knowledge of the plants' lifecycles in order to effectively plan gathering activities. In order to predict the growth patterns and maturation rates of these desert root crops, a GIS model was …


Transportation And Land Use Patterns: Monitoring Urban Change Using Aerial Photography, Portland, Oregon 1925-1945, Paul Hagen Fyfield Jan 2003

Transportation And Land Use Patterns: Monitoring Urban Change Using Aerial Photography, Portland, Oregon 1925-1945, Paul Hagen Fyfield

Dissertations and Theses

American urban neighborhoods are a patchwork; the spatial arrangement of types is a reflection of the dominant transportation technology at the time of their development. The earliest suburban areas were made accessible by fixed route systems such as the electric streetcar, followed by the widespread adoption of the automobile; each transportation epoch resulted in characteristic patterns of land use. This study uses aerial photographic coverage of Portland, Oregon from the years 1925, 1936, and 1945, a time of decline for the once popular trolley lines and dramatic increase in automobile usage, to monitor change within the residential areas of Portland's …


Feng Shui And Chinese Rituals Of Death Across The Oregon Landscape, Andrew Ryall Briggs Mar 2002

Feng Shui And Chinese Rituals Of Death Across The Oregon Landscape, Andrew Ryall Briggs

Geography Masters Research Papers

Paper 2: Upwards of 20,000 Chinese migrated to Oregon before 1890. Upon their deaths many were interred in "Chinese cemeteries." In China, the placement of cemeteries is an important aspect of the traditional Chinese religion. This paper asks if the early Chinese practiced the same Feng Shui in the placement of the Oregon gravesites. While Feng Shui is not codified, there are a few general principles to determine graveyard placement, and by comparing Oregon Chinese gravesites with that required for proper Feng Shui placement, concluded that the early Chinese immigrants may have followed the precepts of traditional Chinese religion in …


On The Edge Of Scarcity: Environment, Resources, Population, Sustainability, And Conflict, Michael N. Dobkowski, Isidor Wallimann Feb 2002

On The Edge Of Scarcity: Environment, Resources, Population, Sustainability, And Conflict, Michael N. Dobkowski, Isidor Wallimann

Program for the Advancement of Research on Conflict and Collaboration

These essays address one of the most pressing and significant issues that humanity has confronted to date - the lack of life-sustaining resources. Michael N. Dobkowski and Isidor Wallimann establish a disturbing but realistic scenario of the disastrous future that awaits humankind as surplus populations collide with dwindling resources. Authors consider a number of cause-and-effect situations on industrialization, biophysical limits, exponential population growth, and genocide, to name a few. This volume is a critical contribution to the field and will serve as an ideal introduction to courses in the environment, population, resources, genocide, and social conflict.

Radiation Budget, Ground Thermal Regime And Hydrological Balance Of A Low Arctic Tundra Basin, Coppermine River, Northwest Territories, David S. Turcotte

Theses and Dissertations (Comprehensive)

The effects of slope, aspect and vegetation cover on the radiation balance and active layer thermal regime of arctic tundra were investigated during the summer of 1999 and the spring of 2000. The study site is located at Daring Lake, N.W.T (64°52'N, 111°35'W) in the Slave Geological Province of the Coppermine River Basin. A sub-basin 14 ha in area and with approximately 30 meters of relief was intensely monitored for hydrological radiation and energy balance components. Initiation of active layer development and subsequent thawing was earlier and more pronounced on predominantly west facing slopes due to increased receipt of incoming …

Spectral Response And Spatial Pattern Of Fraser Fir Mortality And Regeneration, Great Smoky Mountains, Usa, Thomas R. Allen Sep 2001

Spectral Response And Spatial Pattern Of Fraser Fir Mortality And Regeneration, Great Smoky Mountains, Usa, Thomas R. Allen

Political Science & Geography Faculty Publications

High elevation Fraser fir (Abies fraseri) forests of the Southern Appalachians have undergone widespread mortality since the introduction of the balsam woolly adelgid in the 1950s. Resulting changes in ecosystem pattern and process (e.g., stand dynamic processes) have greatly affected floral and faunal communities. In this project, we integrated field observations, geographic information system topographic models, and 1988–1998 satellite imagery to analyze spatial and temporal conditions of Fraser fir and spruce-fir ecosystems in Great Smoky Mountains National Park. Tasseled cap indices (brightness, greenness, and wetness) and associated spectral changes for Landsat TM digital data were statistically modeled by …


Downscaling Temperature And Precipitation: A Comparison Of Regression-Based Methods And Artificial Neural Networks, Justin T. Schoof, S C. Pryor Jan 2001

Downscaling Temperature And Precipitation: A Comparison Of Regression-Based Methods And Artificial Neural Networks, Justin T. Schoof, S C. Pryor

Publications

A comparison of two statistical downscaling methods for daily maximum and minimum surface air temperature, total daily precipitation and total monthly precipitation at Indianapolis, IN, USA, is presented. The analysis is conducted for two seasons, the growing season and the non-growing season, defined based on variability of surface air temperature. The predictors used in the downscaling are indices of the synoptic scale circulation derived from rotated principal components analysis (PCA) and cluster analysis of variables extracted from an 18-year record from seven rawinsonde stations in the Midwest region of the United States. PCA yielded seven significant components for the growing …


An Examination Of Commercial Medicinal Plant Harvests, Mount Hood National Forest, Oregon, Shannon Michelle Campbell Jun 2000

An Examination Of Commercial Medicinal Plant Harvests, Mount Hood National Forest, Oregon, Shannon Michelle Campbell

Dissertations and Theses

During the past fifteen years, non-timber or special forest products have become an important economic resource in the Pacific Northwest. These products are primarily derived from understory species and contribute approximately $200 million to the regional economy. Medicinal plants are a little researched component of the non-timber forest product industry that relies on cultivated and wildcrafted (or wild-collected) medicinal plant species. This study examines the commercial extraction of wildcrafted medicinal plants from Mount Hood National Forest. Specifically, this study documents the medicinal plant species extracted from Mount Hood National Forest, their annual yield amounts, harvesting methods, and the changes in …


Mapping Stamp Sand Dynamics: Gay, Michigan, Thomas H. Rasmussen Jun 2000

Mapping Stamp Sand Dynamics: Gay, Michigan, Thomas H. Rasmussen

Masters Theses

Monitoring coastal change is an important undertaking because a high percentage of the population lives within close proximity to coastal areas. This paper examines a portion of Lake Superior's shoreline where coastal change has been shaped by the introduction of 25 million tonnes of stamp sand, a man-made sediment. Longshore currents erode and deposit sediment changing the geomorphology of the coastline on both a short- and long-term basis. This movement may be documented through comparison of archival and current air photos. A series of historical air photo mosaics were input to a Geographic Information System (GIS). The GIS was used …


Signs Of Popular Ecology In The Ecotourism Landscape Near Tikal National Park, Guatemala, Michael Mooradian Lupro May 2000

Signs Of Popular Ecology In The Ecotourism Landscape Near Tikal National Park, Guatemala, Michael Mooradian Lupro

Dissertations and Theses

Ecotourism is a common conservation and development strategy in the Maya, Forest region. New sites of ecotourism consumption, such as El Rematé near Tikal National Park in Guatemala, are developing in response to consumer demand for budget accommodations in this attractive cultural and natural setting. This study analyzes new ecotourism infrastructure developments in El Rematé for signs that this tourism draws on ecological imagery as expressed in popular media - or popular ecology - not on the natural and cultural ecology of the region that is the target of international conservation efforts. Analysis suggests that ecotourism entrepreneurs who effectively associate …

Visualizing Uncertainty Of The Great Plains Boundary, Sonja Lynn Rossum May 1998

Visualizing Uncertainty Of The Great Plains Boundary, Sonja Lynn Rossum

Department of Geography: Dissertations, Theses, and Student Research

Geographic regions all have some degree of uncertainty, though this is seldom represented on their maps. The Great Plains is an excellent example of how even a well known and widely accepted region can be a source of cartographic confusion. This region is fuzzy in nature, with few landforms or sharp changes in characteristics to help locate the boundary line. Also, the act ofregionalization itself is a highly subjective process, using defining criteria and methods of mapping selected by the cartographer.

The uncertainty of the Great Plains boundary location is shown by comparing many such interpretations from individual cartographers, all …

The Coming Age Of Scarcity : Preventing Mass Death And Genocide In The Twenty-First Century, Michael N. Dobkowski, Isidor Wallimann

Books

The structure of the book is simple. The first part analyzes major forces having an impact on the survivability of civilization as we know it into the twenty-first century. It outlines the challenges we face, including overpopulation, pressure upon the land, migration, ecological damage, and social instability. In part two, we present more detailed discussion of the problem of scarcity and how it relates to conflict. The authors in this section argue that the current level of human activity is unsustain­able. They demonstrate that population growth in particular affects the natural world and can affect the social order and international …

Is it possible to look out over the Ural Mountains and see Appalachia? To find the character of the American West in the vast open space of Siberia? To smell the citrus and feel the warm sun of the Black Sea coast and be struck with a sense of Florida?

This book is based on just such an idea: that we can look beyond our borders and discover fundamental realities about places that transcend differences of culture, language, and politics. Five American and four Russian geographers wrote this book to provide glimpses of understanding about the United States and Russia. …

Description Of The Sections And Subsections Of The Interior Highlands Of Arkansas And Oklahoma, Thomas L. Foti, George A. Bukenhofer

Journal of the Arkansas Academy of Science

Sections and subsections of the Interior Highlands of Arkansas and Oklahoma are redefined, mapped and briefly summarized. The map was produced to support the Ozark- Ouachita Highlands Assessment (OOHA), being conducted by the USDA Forest Service. It revises the USDA Forest Service map "Ecological units of the eastern United States, first approximation" by Keys et al. (1995) and the earlier maps of the natural divisions of Arkansas (Foti, 1974; Foti, 1976; Pell, 1983) to reflect new knowledge and to achieve consistency with units recognized in Missouri. Four sections (natural divisions) are defined as opposed to the three of the previous …


Patterns Of Time, Place, And Culture: Land Use Zoning In Portland, Oregon, 1918-1924, Meg Merrick Jan 1998

Patterns Of Time, Place, And Culture: Land Use Zoning In Portland, Oregon, 1918-1924, Meg Merrick

Dissertations and Theses

Until recently, few have questioned the notion that the separation of uses in land use zoning is inherently correct. Many observers of the city are now suggesting that zoning, as it has been practiced in this country over the last 80 years, has created cities that are fractured and function poorly. Others propose that zoning should be reconsidered as a remedy for urban dysfunction. They suggest that the whole notion of zoning be rethought.

The purpose of this study is to uncover some of the underlying rationales and methodologies that set the model for zoning. This study examines the rationales …


Satellite Remote Sensing For Measuring The Urban Forest Of Portland, Oregon, A. Paul Newman Sep 1997

Satellite Remote Sensing For Measuring The Urban Forest Of Portland, Oregon, A. Paul Newman

Dissertations and Theses

Digital pattern recognition methods were used to produce two maps of urban vegetation from LANDSAT Thematic Mapper for the City of Portland, Oregon. The image was acquired on July 7, 1991 and the spectral bands used were 2, 4, 5 and a ratio of 3 and 4. The two maps represent vegetation amount and vegetation type.

Due to the extreme heterogeneous nature of the urban environment, these maps were developed using techniques to reduce and manage the amount of spectral variation. This included purging non-vegetated cells from the multispectral image, and then stratifying the image into "spectral subdivisions" using tools …


Evaluation Of Selected Atmospheric Indices For The Prediction Of Thunderstorms At Omaha, Nebraska, Fred Ladehoff May 1997

Evaluation Of Selected Atmospheric Indices For The Prediction Of Thunderstorms At Omaha, Nebraska, Fred Ladehoff

Open Access Master's Theses (through 2010)

This study examines the values of five stability indices (the Showalter Index, the K Index, the Vertical Totals Index, the Cross Totals Index, and the Total Totals Index) for Omaha, Nebraska during the months of March through September, 1964 through 1973. Index means during thunderstorm periods and non-thunderstorm periods should show a distinct difference. Even though indices can be an important tool, it must be accentuated that indices should never be used as the sole factor in the prediction of thunderstorm or non-thunderstorm occurrences. This study shows that even at the highest skill scores, many mistakes would be made in …
