Detecting And Mapping The Michigan Vegetation Tension Zone Using Ecological Indicators, Janice Marie Fulford

Masters Theses

Ecotones are areas of transition between adjacent ecosystems that exist at various geographic scales, and are useful in measuring climatic changes. Ecotones are defined by their length and breadth and the ability to detect and map an ecotone from a specific period in time would be useful in measuring current and future change.

The study focused on a 1880's vegetation ecotone in the center of Michigan's Lower Peninsula. This was achieved by deriving ecological variables from the U.S. public land survey's tree species data. These variables were then used to ascertain the length of the ecotone by finding the boundary …

A Model Of The Natural Spread Of The Invasive Insect Species Emerald Ash Borer In The Lower Peninsula Of Michigan, Jennifer L. Weller

Masters Theses

More than 8 million ash trees in southeast Michigan have been killed by an infestation of the invasive insect species emerald ash borer (EAB). Since its identification in July 2002, EAB has been found in Ontario (Canada), Ohio, Indiana, and across Michigan. To date, EAB research has concentrated on the entomological classification and no systematic prediction of the pest's diffusion has been made.

This research presents a predictive model for the spread of EAB across the Lower Peninsula of Michigan. Limited data on ash tree population distribution, ·. infestation distribution, and the dispersal rate of the emerald ash borer required …

The Changing Demographic, Legal, And Technological Contexts Of Political Representation, Benjamin Forest

Dartmouth Scholarship

Three developments have created challenges for political representation in the U.S. and particularly for the use of territorially based representation (election by district). First, the demographic complexity of the U.S. population has grown both in absolute terms and in terms of residential patterns. Second, legal developments since the 1960s have recognized an increasing number of groups as eligible for voting rights protection. Third, the growing technical capacities of computer technology, particularly Geographic Information Systems, have allowed political parties and other organizations to create election districts with increasingly precise political and demographic characteristics. Scholars have made considerable progress in measuring and …

Assimilation And Differences Between The Settlement Patterns Of Individual Immigrants And Immigrant Households, Mark Ellis, Richard Wright

Dartmouth Scholarship

Analyses of immigrant settlement patterns typically rely on counts of foreign-born individuals by neighborhood, metropolitan area, state, or region. As an alternative, this study classifies immigrants and their descendents into household types to shift attention from individuals to relationships between individuals. The study uses pooled current population survey data to identify seven household types, six of which have various degrees of immigrant or second-generation presence. The research compares distributions of first- and second-generation immigrants with different types of households that include first- and second-generation immigrants. Our analysis shows that the geography of immigration based on households differs considerably from geographies …

Historical Land Cover Impacts On Water Quality In The Provo River Watershed, 1975 - 2002, Fredric James Donaldson

Theses and Dissertations

The Provo River watershed has experienced land cover change over the past several decades. Land cover influences water quality inasmuch as land cover determines the type and quantity of non-point source (NPS) pollutants that may enter the water. This study examines the historical impacts of land cover changes on water quality in the Provo River using remote sensing and statistical analysis. Statistical correlations and linear regressions were used to study the relationship between various land cover types and water quality variables for six years between 1975 and 2002. This thesis supports research finding myriad impacts of urban land cover on …

Lost And Found: The Imagined Geographies Of American Studies, Cindi Katz

Publications and Research

In the days after September 11th, 2001, and continuing until now, the national guard and other military personnel fanned out around New York City. Automatic rifles slung over their camouflaged shoulders, they "guarded" New York City's transportation stations, vital corners and thoroughfares, marquee buildings, and each and every bridge and tunnel entrance. Their comportment was usually cordial and rarely vigilant. Exuding the antithesis of an urban sensibility, they complemented the beefy boredom of the police who usually stood nearby, with an almost surreal sense of incredulity; not just "Why am I here?" but a sort of bafflement that anyone would …

Cultural Economy: A Critical Review, Chris Gibson, Lily Kong

Research Collection School of Social Sciences

This article reviews work on 'cultural economy', particularly from within geography, and from other disciplines, where there are links to overtly geographical debates. We seek to clarify different interpretations of the term and to steer a course through this multivalency to suggest productive new research agendas. We review and critique work on cultural economy that represents a relatively straightforward economic geography, based on empirical observation while theoretically informed and driven by debates about Fordism and post-Fordism, agglomeration and cluster theory. Some of these ideas about cultural economy have proven attractive to policy-makers and we map a normative script of cultural …

An Assessment Of The Impacts Of Climate Change On The Upper Clackamas River Basin With A Distributed Hydrologic Model, David Graves

Dissertations and Theses

The Pacific Northwest is dependent on seasonal snowmelt for water resources that support a significant portion of its economy. Increased temperatures resulting from higher concentrations of atmospheric greenhouse gases may cause disruptions to these resources because of reductions in the annual snowpack and variations of the timing of snowmelt. This study reconstructs and applies a GIS-based distributed hydrologic model at a monthly scale to assess the effects of future climate change on runoff from the Upper Clackamas River Basin (located near Portland, Oregon). Historic flow data and snow measurements are used to calibrate and test the performance of the hydro …

Big-Bodied Males Help Us Recognize That Females Have Big Pelves, Robert G. Tague

Faculty Publications

Schultz ([1949] Am. J. Phys. Anthropol. 7:401-424) presented a conundrum: among primates, sexual dimorphism of the pelvis is a developmental adjunct to dimorphism in other aspects of the body, albeit in the converse direction. Among species in which males are larger than females in body size, females are larger than males in some pelvic dimensions; species with little sexual dimorphism in nonpelvic size show little pelvic dimorphism. Obstetrical difficulty does not explain this relationship. The present study addresses this issue, evaluating the relationship between pelvic and femoral sexual dimorphism in 12 anthropoid species. The hypothesis is that species in which …

Time-Series Analysis Of Clusters In City Size Distributions, Ahjond S. Garmestani, Craig R. Allen, K. Michael Bessey

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Complex systems, such as urban systems, emerge unpredictably without the influence of central control as a result of adaptive behavior by their component, interacting agents. This paper analyses city size distributions, by decade, from the south-western region of the United States for the years 1890–1990. It determines if the distributions were clustered and documents changes in the pattern of clusters over time. Clusters were determined utilizing a kernel density estimator and cluster analysis. The data were clustered as determined by both methods. The analyses identified 4–7 clusters of cities in each of the decades analysed. Cities cluster into size classes, …

Re-Presenting The Religious: Nation, Community And Identity In Museums, Lily Kong

Research Collection School of Social Sciences

This paper examines the roles that museums play as 'unofficially sacred' places, underscoring or challenging the religious life of a people and 'nation'. It focuses on three key questions: (1) Do sub-national and transnational religious formations pose a challenge to or present opportunities for nation-building strategies, and what part do museums play in this struggle? (2) In what ways do re-presentations of religion in museums contest or reinforce religious community and identity? and (3) What challenges do museum displays pose to the understanding of religious meanings? This paper explores these three key questions about the intersection of religion with politics …

Geogdl: A Web-Based Approach To Geography Examination, Ee Peng Lim, Dion Hoe-Lian Goh, Yin-Leng Theng

Research Collection School Of Computing and Information Systems

The traditional educational approach with students as passive recipients has been the subject of criticism. A constructivist learner-centered approach towards education has been argued to produce greater internalization and application of knowledge compared to the traditional teacher-centered, transmission-oriented approach. Nevertheless, contemporary instructional design models argue for the use and integration of both approaches especially in complex learning tasks. This paper describes GeogDL, a Web-based application developed above a digital library of geographical resources for Singapore students preparing to take a national examination in geography. GeogDL is unique in that it not only provides an environment for active learning, it also …

Street Trees In The Urban Forest Canopy: Portland, Oregon, Joseph Poracsky, David Banis

Geography Faculty Publications and Presentations

Attempts to identify the contribution of street trees to the overall urban forest of a city have been rare and lack consensus on how to measure that contribution – percentage of trees, percentage of canopy cover, or percentage of leaf area. The actual numeric values presented in the literature also vary over a broad range and often are based on estimates, extrapolations from aggregated data, or simply stated with no empirical data referenced. This study was undertaken to evaluate the contribution of street trees to canopy in Portland, Oregon. The study involved both visual and digital analysis of multi-band aerial …

On Reduction Of Risks In Uxo And Mine Detection Using Remote Sensing Systems And Related Synthetic Image Simulation, Charles R. Bostater

Ocean Engineering and Marine Sciences Faculty Publications

It is important to understand remote sensing systems and associated platforms in the context of autonomous or semi-autonomous designs for (robotic & mechatronics) that may be affect the motion control or stabilization aspects of the imagery, scan lines or fixed points scanned. This need can be most easily conceived as being related to the reduction of risks associated with false detection as well as the risks associated with hardware and software failure and risks associated with the actual operation of sensor and platform in dangerous environments. Thus safety is ultimately our concern when it comes to risk assessment. This paper …

Fire-Induced Albedo Change And Its Radative Forcing At The Surface In Northern Austrailia, Y. Jin, David P. Roy

GSCE Faculty Publications

This paper investigates the impact of fire on surface albedo and the associated radiative forcing over 56% of continental Australia encompassing the fire-prone northern tropical savanna. Fire-affected areas and albedos are derived for the 2003 fire season using daily Moderate Resolution Imaging Spectroradiometer (MODIS) surface reflectance data. Near-infrared and total shortwave albedos are observed to generally decrease after fire occurrence. Regionally, the total shortwave albedo drops by an average of 0.024, with increasing reductions as the dry season progresses and larger reductions in grasslands than woody savannas. These fire-induced albedo changes exert a positive forcing at the surface that increases …

Whistler’S Fog And The Aesthetics Of Place, Bruce Janz

Reconstruction: Studies in Contemporary Culture

The concept of place has usually been understood as either a phenomenological, epistemological, or ethical category. An understanding of place as aesthetic or rhetorical, on the other hand, tends to focus on the widely varied uses of the concept. First, I sketch out the wide range of uses of place, that have been drawn from writings on the concept. These uses are not definitions of place, but rather functions that the term performs. Place stands in for other ideas, and allows access to different aspects of human experience. Second, I will draw from this range of uses some ideas about …

On Joel Weishaus' Forest Park: A Journal, Rania Masri

Reconstruction: Studies in Contemporary Culture

[First paragraph]

How do we define place? How do we develop our sense of identity and how do we recognize that development? With our constantly changing locations and with our locations themselves constantly changing into more urbanized areas, how do we locate and understand ourselves within our idea of place? How does our relationship with 'nature' touch our lives? In essence, how do we live, with - and within - ourselves?

A Politics Of Place: Reading The Signs At Walden Pond, Joy Ackerman

Reconstruction: Studies in Contemporary Culture

Pilgrimage begins with a vision of place. Look down! The holy is here beneath your feet. The boundary of heaven and earth is not the distant horizon, ever out of reach. It shimmers on the surface of the water. As Thoreau ponders the sky reflected in Walden Pond, he sees the earth encompassed within the spiritual realm. The concept of ‘sacred geography’ also suggests such an embrace. Through the recognition of a pattern in the landscape or the orientation of a temple in the holy city, sacred geography claims that the landscape is a map of the divine order, the …

The Edge Of The World, Joy Kennedy

Reconstruction: Studies in Contemporary Culture

“The Edge of the World” tells a true story of a mapping expedition in the second longest cave in Texas. When her survey group becomes lost inside the cave, the author uses the experience to propel questions of the duplicity of maps and the ambiguities of human perception. Detailed are the gritty nuances of caving that the average tourist never experiences: the tightness of squeezes, digging for air flow, and pushing for passages. The author finally questions if the blank spaces on maps should really be filled in with new discoveries, for perhaps something is being lost in the process.

Discovering Your Cinematic Cultural Identity, John Shelton Lawrence, Marty S. Knepper

Reconstruction: Studies in Contemporary Culture

This paired set explores the experience of cultural identities constructed by and experienced through popular film. The essay “Discovering Your Cinematic Cultural Identity” reflects the authors’ decades of residence in the state of Iowa and their personal irritation with the stereotypes that Hollywood regularly calls upon in evoking the American rural. We gained a new perspective on this sort of imagery when it surfaced again in Field of Dreams (1989) and The Bridges of Madison County novel (1992) and film (1995). Each of these films triggered unprecedented film tourism for the state. Through an exploration of these films and others …

Nurturing Sense Of Place Through The Literature Of The Bioregion, Patrick Howard

Reconstruction: Studies in Contemporary Culture

This paper explores the possibility that a participatory engagement with the literature of the bioregion, in this case the North Atlantic coast, may work against the life alienating tendencies of our modern culture, to reaffirm and renew our children’s consciousness of and sensitivity for their place in a larger Earth community. We are in need of another way of knowing our place, a way to activate and reactivate the complex articulations and relations of things. Through the literature of the bioregion and a bodily, imaginative and participatory engagement with the other-than-human, children can return to the conditions of human embeddedness …

On Joel Weishaus' Forest Park: A Journal, Christine Cusick

Reconstruction: Studies in Contemporary Culture

[First paragraph]

I tend to have an often stubborn suspicion of the convergence of art and technology, language that loses and finds us in the throes of new and unbound understanding somehow, seems diminished when the materiality of its record cannot be felt, when visceral responses cannot make a palimpsest of the text through the marginalia of an earnest reader. And so, when I first heard mention of a highly respected poet and thinker chronicling his time-felt ruminations and intuitions on cyberspace, I was initially hesitant to pursue the encounter. However, my hesitation quickly turned to humble engagement as I …

Highway Interchanges, Transportation And Land Use: An Exploration Of Changes In Transportation Volumes And Land Use Factors Within Interchange Catchments, Matthew Hampton

Geography Masters Research Papers

Highway interchanges provide the interface for and moderate access to the surface street system and help control congestion. Understanding the relationship between land use and transportation near highway interchanges can help to direct resources where they are most needed to maintain the integrity of the adjacent road system. This paper characterizes and ranks highway interchange areas in the Portland, OR Metropolitan Planning Organization (MPO) area with respect to changes in traffic volume and determines what factors are associated with these impacts. This study compares the transportation, population and land use patterns around 78 highways and freeway interchanges over two time …

Ambivalent Landscapes: An Historical Geography Of Recreation And Tourism On Mount Hood, Oregon, Ryan Franklin Mitchell

Dissertations and Theses

Mount Hood is an Oregon icon. The mountain has as long and rich a history of recreation and tourism as almost any other place in the American West. But contemporary landscapes on Mount Hood reveal a recreation and tourism industry that has struggled to assert itself, and a distinct geographic divide is evident in the manner in which tourism has been developed. Why? In this study I chronicle the historical geography of recreation and tourism on Mount Hood. I examine the evolution of its character and pattern, and the ways in which various communities have used it to invest meaning …

Fuel Model Development And Fire Simulation Analysis In The Wildland-Urban Interface: The Case Of Forest Park, Portland, Oregon, David Malcolm Kuhn

Dissertations and Theses

Forest Park, a 5,000 acre heavily-forested park within the city limits of Portland, Oregon was selected as the study area for performing a fire simulation analysis. A well-documented fire swept over a large area of the park in 1951, and provides both direct inputs, including the ignition point, and context for the present day fire simulations. The goal of the research was two fold. First, determine the difference between small area simulations using standard and custom surface fuel models. Second, determine if fire simulation can be an effective tool in assessing fire danger and behavior in a wildland-urban interface environment …

Visualizing Complexity : A Spatial Analysis Of Decorative Geometric Pattern In The Islamic World, 900-1400 Ad, Tracy Elizabeth Harrison

Dissertations and Theses

This study explores how the use of complex decorative geometric patterns in Islamic architecture spatially relates to advances in the fields of science and philosophy in the Islamic world between the ninth and fourteenth centuries. This project examines hypotheses developed by vario~s scholars on the forces that shaped the use of these patterns (known as the geometric mode) in Islamic architecture. The prevailing assumption that advances in mathematics contributed to the use of the geometric mode is used as a starting point for subsequent analysis.

For this study, two spatial databases were created. One contains over two hundred and twenty …

Successful Superfund Site Restoration: A Case Study Of Independence Grove Forest Preserve, Linnea E. Hruska

Masters Theses

The United States Superfund program has been quite controversial since it was established under the Comprehensive Environmental Response, Compensation, and Liability Act in 1980. Several people feel that the enormous amounts of time and money invested in the Superfund program are not worthwhile because so many sites remain far from being cleaned up. Nevertheless, some successful site restorations have been achieved under this program. The Petersen Sand & Gravel site is one of these success stories. This thesis examines why the Petersen Sand & Gravel site was able to experience such success under the Superfund program by taking history, economics, …
