Social Interaction At The Maya Site Of Copan, Honduras: A Least Cost Approach To Configurational Analysis, Heather Richards-Rissetto

Department of Anthropology: Faculty Publications

In this article, I employ least cost paths using GIS to measure the relationship between site configuration and social connectivity at the ancient Maya site of Copan, Honduras. I investigate two questions. First, did people of different social classes experience varying degrees of social connectivity? Second, did people living in different parts of the city experience difference degrees of social connectivity? Ultimately, the goal is modify traditional configurational analysis using least cost analysis (LCA) to identify how social hierarchy was embedded in landscapes and how ancient people may have strategically manipulated landscapes to structure social interaction and community organization.

Modeling Intermittent And Perennial Headwater Stream Origins In North Carolina., Kevin Macleod

Theses and Dissertations

Low-order headwater streams, a link between the upland landscape and larger streams within a watershed, affect watershed hydrology. Yet current widely available maps inadequately depict headwater streams, underestimating channel length or omitting channels entirely. Intermittent and perennial headwater streams each provide unique habitat. Until recently, it has not been possible to accurately delineate these streams or predict channel flow durations without fieldwork. Recent advances in remote sensing may allow more accurate headwater stream mapping.

Methods for mapping intermittent and perennial headwater streams with a GIS-based modeling approach coupled with field verification were adapted, tested, and evaluated. Four models were developed …

Potential Wolverine Habitat Vs. Winter Recreation. Conflict In Colorado!, Paul Quigley

Geography and the Environment: Graduate Student Capstones

The Global list of endangered species of flora and fauna is growing, with the most highly specialized species often at ‘critically endangered’ status. Managing these populations effectively involves numerous and varied organizations, conflicting motivations, arbitrary anthropogenic boundaries and often most importantly, data compilation and management. We are seeing many more reintroductions of locally extirpated species back into habitats of historical prevalence – and as extreme a method of conservation as this is, there is still a need for more extreme methods. High profile and highly specialized endangered species are often managed in a ‘crisis’ mode, where complex behaviors and interactions …

Applying Gis Metrics To Determine Degree Of Glacial Modification In Mountainous Landscapes, Carl Delbert Swanson Ii

All Master's Theses

The ability to quantitatively assess the degree of glaciation in mountainous areas can be a powerful tool in unraveling the evolution of landscapes, and provide key insights in regions where field research is difficult. Here we determine, test, and apply metrics that assess the relative degree of past glacial modification in mountainous landscapes. Results show that slope results can be used to quantitatively assess the degree to which an area is modified by glaciation. In particular, analysis of basins using slope frequency distribution curves and slope vs. elevation plots capture steeper slopes, flatter valley bottoms, cirques, and arêtes of glaciated …

Transboundary Political Ecology In The Peru-Brazil Borderlands: Mapping Workshops, Geographic Information, And Socio-Environmental Impacts, David S. Salisbury, A. William Flores De Melo, Pedro Tipula Tipula

Geography and the Environment Faculty Publications

Development, resource, and settlement frontiers inspired by national policies and global demand continue to expand into the international boundary lands of Amazonia. National policies promote development and conservation projects on lands already inhabited and managed. Regional governments are increasingly frustrated by the inadequate and outdated geographic information available to solve overlapping claims and improve planning in sensitive border regions. The resulting combination of inappropriate policies, contested resources, and poor geographic information in the borderlands create impacts not only for national, regional, and local landscapes and livelihoods but also foreign relations due to transboundary effects. This article uses a transboundary political …

Análisis De Los Impactos Socio-Ambientales De Las Carreteras En La Amazonía: Carretera De Puerto Esperanza A Iñapari En Perú, George Appling, David S. Salisbury

Geography and the Environment Poster Presentations

La Cuenca del Purús está situada en las regiones de Ucayali y Madre de Dios en el sudeste del Perú. Además del Rio Alto Purús, la cuenca abarca un parque nacional, una reserva comunal, reservas territoriales para pueblos indígenas aislados, territorios indígenas y un pueblo pequeño (Figura 1). En el año 2004, el Gobierno Peruano creó el Parque Nacional Alto Purús, el más grande en el Perú, para preservar una de las secciones mejor conservadas del bosque tropical en el bioma Amazónico. Como se demuestra en la Figura 1, la Reserva Comunal Purús colindante, sirve como zona de amortiguamiento entre …

Chemistry & Biochemistry Faculty Publications

This work reports the first remote sensing measurements of atmospheric HFC-23 (CHF₃) using solar occultation measurements made by the Atmospheric Chemistry Experiment Fourier transform spectrometer (ACE-FTS) and the Jet Propulsion Laboratory Mark IV (MkIV) balloon interferometer. A total of 8809 ACE occultations measured between 2004 and 2010 have been processed, along with 24 MkIV occultations measured between 1989 and 2007. ACE data (yearly averages over the 10-25 km altitude range) in the tropics/subtropics (40°S-40°N) reveal a trend of 4.0 ± 1.6% per year in the growth of HFC-23 for 2004-2009 (or 3.9 ± 1.2% per year for 2004-2010), …

Toxic Tourism: Promoting The Berkeley Pit And Industrial Heritage In Butte, Montana, Bridget R. Barry

Department of History: Dissertations, Theses, and Student Research

Butte, Montana’s Berkeley Pit and its deadly water are a part of the country’s largest Superfund site. In 1994 the United States Environmental Protection Agency (EPA) issued a Record of Decision designating Butte, along with the neighboring town and mining site of Anaconda (twenty-five miles northwest of Butte), and 120 miles of Montana’s Clark Fork River as a single Superfund complex. The vast mining operations undertaken in the area, including five hundred underground mines and four open pit mines, have resulted in hazardous concentrations of metals in groundwater, surface water, and soils.

Butte’s mines once extracted more tons of copper …

Review Of Griffith Taylor – Visionary Environmentalist Explorer By Carolyn Strange And Alison Bashford, Christina E. Dando

Geography and Geology Faculty Publications

Few would argue the inherently visual nature of geography, our use (and love of) maps, our emphasis on fieldwork and observation. Carolyn Strange and Alison Bashford’s biography Griffith Taylor: Visionary, Environmentalist, Explorer is as much a visual biography as a textual one, drawing on extensive visual materials as well as diaries and letters. Through images and texts, Strange and Bashford create a portrait of a complicated geographer, revealing a leading geographer of the twentieth century whose contributions cover the spectrum and the globe.

Book Review Of Civic Discipline: Geography In America, 1860–1890 By Karen M. Morin, Christina E. Dando

Geography and Geology Faculty Publications

Karen Morin's Civic Discipline: Geography in America, 1860–1890 examines nineteenth-century American geography practices outside of academia and the contributions of Charles P. Daly, New York judge and American Geographical Society (AGS) president. Daly was not an academic geographer yet had tremendous influence over public geographic knowledge, impacting the actions of many actors on many stages. Civic Discipline is not a biography but rather “a sociology of Charles Daly's geography—a social geography,” illuminating an area frequently ignored in geography's history: the ways in which Daly and the AGS impacted the American geographical imagination (p. 3).

New Methods For The Discovery And Characterization Of Lunar Lava Tubes Using Lunar Reconnaissance Orbiter Data, Jonathan Arthur Meyer

Open Access Theses & Dissertations

Lava tubes have the potential to serve as a sustainable solution to long-term lunar habitation by providing protection from radiation and micrometeorite bombardment while potentially providing resources in the form of trapped water ice. They also pose compelling science targets in their own right. While the potential benefits of utilizing lunar lava tubes is clear, their discovery is less straightforward. Formation processes for lava tubes do not always result in a surface expression, making their discovery using remotely sensed imagery difficult. Furthermore, there is the potential for lava tubes to be covered by secondary lava flows, impact ejecta, or other …

Vertical Deformation Along The San Andreas Fault, Garrett Thornton

Open Access Theses & Dissertations

There have been numerous M 6+ earthquakes along the San Andreas Fault System (SAFS) (Schwartz et al., 1984) (Figure. 1.1) in the historical past. These rupture events have created millions of dollars worth of damage, and have been responsible for multiple lives lost. An improved understanding of the motions and crustal characteristics along the SAFS can lead to better hazard mitigation (Bakun et al., 2005). Horizontal crustal motions of the SAFS have been widely studied and applied to seismic hazard models (WGCEP, 2007), however vertical motions are not often utilized due to their complicated origin and sometimes large uncertainties. This …

Use Of Environmental Isotope Tracer And Gis Techniques To Estimate Basin Recharge, Abdulganiu A.A. Odunmbaku

Open Access Theses & Dissertations

The extensive use of ground water only began with the advances in pumping technology at the early portion of 20th Century. Groundwater provides the majority of fresh water supply for municipal, agricultural and industrial uses, primarily because of little to no treatment it requires. Estimating the volume of groundwater available in a basin is a daunting task, and no accurate measurements can be made. Usually water budgets and simulation models are primarily used to estimate the volume of water in a basin.

Precipitation, land surface cover and subsurface geology are factors that affect recharge; these factors affect percolation which invariably …

Academic Freedom, Intellectual Diversity, And The Place Of Politics In Geography, Reecia Orzeck

Faculty Publications - Geography, Geology, and the Environment

This paper examines the conservative critique of higher education in the USA. I argue, first, that the right's call for greater “intellectual diversity” in American higher education should be understood as an attack on the professional self-regulation and disciplinary autonomy that are central to academic freedom in this country. Second, I suggest that the right's politicization of politics in the academy brings to light the importance of our developing a vision of the university that accounts for rather than disavows the political nature of the work we do.

Securing Access To Lower-Cost Talent Globally: The Dynamics Of Active Embedding And Field Structuration, Stephan Manning, Joerg Sydow, Arnold Windeler

Management and Marketing Faculty Publication Series

This article examines how multinational corporations (MNCs) shape institutional conditions in emerging economies to secure access to high-skilled, yet lower-cost science and engineering talent. Based on two in-depth case studies of engineering offshoring projects of German automotive suppliers in Romania and China we analyze how MNCs engage in ‘active embedding’ by aligning local institutional conditions with global offshoring strategies and operational needs. MNCs thereby contribute to the structuration of field relations and practices of sourcing knowledge-intensive work from globally dispersed locations.Our findings stress the importance of institutional processes across geographic boundaries that regulate and get shaped by MNC activities.

Synergistic Use Of Remote Sensing And Modeling For Tracing Dust Storms In The Mediterranean, D. G. Kaskaoutis, Anup K. Prasad, P. G. Kosmopoulos, P. R. Sinha, S. K. Kharol, P. Gupta, Hesham El-Askary, Menas Kafatos

Mathematics, Physics, and Computer Science Faculty Articles and Research

This study focuses on the detection of the dust source region and monitoring of the transport of the dust plume from its primary outflow to final deposition. The application area is the Sahara desert and the eastern Mediterranean, where two dust events occurred during the period 4–6 February 2009, an unusual event for a winter period. The Aqua-MODIS and OMI observations clearly define the spatial distribution of the dust plumes, while the CALIPSO observations of total attenuated backscatter (TAB) at 532 nm, depolarization ratio (DR), and attenuated color ratio (1064/532 nm) on 5 February 2009 provide a clear view and …

Challenging Rust: Race And Rightsizing In Detroit, An American Post-Industrial Context, Andrienne Palchick

Geography Honors Projects

Cities in the American Rustbelt face the considerable challenges of depopulation and economic decline, but they are also increasingly viewed as places ripe with opportunities for innovation and an exciting re-imagination of urban space. This paper examines the Detroit Works Project, a re-envisioning and revitalization initiative in Detroit, to explore larger questions of accessibility and inclusion in U.S. post-industrial cities. It is an investigation of how to structure these revitalization efforts within cities where networks of actors, who invested in urban industrial growth, created policies which built the geographies of unequal access, racial segregation, and systemic marginalization that persist today.

Global Production Networks, Relational Proximity, And The Sociospatial Dynamics Of Market Internationalization In Bolivia's Wood Products Sector, James T. Murphy

Geography

This article advances conceptualizations of global production networks (GPNs) through an analysis of the relational processes that firms in Bolivia's growing wood products industry use to build ties to international markets. Both large- and small-scale manufacturers are increasingly internationalizing their operations in response to the global demand for tropical hardwoods and decentralization of control over the country's forest resources. These firms use four different types of production networks and networking practices to develop international market ties. Each of these networks is distinguishable by its entry barriers, value-creation possibilities, upgrading strategies, and the cognitive, social, and cultural factors that influence who …

Accelerating Anthropogenic Land Surface Change And The Status Of Pleistocene Drumlins In New England, Deborah W. Woodcock, John S. Rogan, Samuel D. Blanchard

Geography

Drumlins are glacially derived landforms that are prominent in the landscape over much of southern New England. We carried out a comprehensive ground-based survey in a three-town study area in eastern Massachusetts with the goals of establishing the extent to drumlins have been altered and assessing the associated environmental consequences and probable driving factors. Results show that many drumlins have been significantly altered through levelling and truncation (creation of steep cut and fill slopes), with projects involving movement of 1-1.5×106 m3 of earth materials not now uncommon. Stormwater and wetlands infractions were documented at all the larger excavation sites and …

Error Propagation In Raster Data Integration: Impacts On Landscape Composition And Configuration, Zachary J. Christman, John Rogan

Geography

Integrating raster-based categorical maps from multiple sources necessitates the transformation of geometric characteristics to compare maps, as in land change analyses. By projecting maps to a new geographic reference framework and scaling pixel values to a new size, distortions of map information are introduced that can affect the proportion and arrangement of thematic classes across the landscape. Using a sample land cover dataset depicting a heterogeneous landscape, this paper examines these impacts using three common raster-based transformation methods and introduces a new vector-based method that minimizes error propagation. While relative class area was best preserved by a nearest-neighbor resampling method, …
