Towards A Collective Spatial Form:An Analysis Of Achill’S Deserted Village, Noel Brady 2015 Technological University Dublin

Towards A Collective Spatial Form:An Analysis Of Achill’S Deserted Village, Noel Brady

Conference papers

This paper examines an earlier study by Bob Kingston and along with onsite observations develops an environmental theory behind the particular siting and location of the deserted village in Achill, Ireland. The paper relies on the survey conducted by Kingston in the first instance but then by translating the material into a different format has concluded on statistically significant evidence of willful and careful planning and design in the construction of the houses.

Spatial And Seasonal Responses Of Precipitation In The Ganges And Brahmaputra River Basins To Enso And Indian Ocean Dipole Modes: Implications For Flooding And Drought, M. S. Pervez, G. M. Henebry

Natural Resource Management Faculty Publications

We evaluated the spatial and seasonal responses of precipitation in the Ganges and Brahmaputra basins as modulated by the El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) modes using Global Precipitation Climatology Centre (GPCC) full data reanalysis of monthly global land-surface precipitation data from 1901 to 2010 with a spatial resolution of 0.5° × 0.5°. The GPCC monthly total precipitation climatology targeting the period 1951–2000 was used to compute gridded monthly anomalies for the entire time period. The gridded monthly anomalies were averaged for the years influenced by combinations of climate modes. Occurrences of El Niño alone significantly …

Objective: To compare sociodemographic and motivational factors for healthcare use and identify desirable health-promoting resources among groups in a low socioeconomic status (SES) community in Chicago, IL. Background: Disparities in health services and outcomes are well established in low SES urban neighborhoods in the United States and many factors beyond service availability and quality impact community health. Yet there is no clear process for engaging communities in building resources to improve population-level health in such locales. Methods: A hospital building project led to a partnership of public health researchers, architects, and planners who conducted community-engaged research. We collected resident data …


Pedestrian Mobility In Denver: A Mixed Methods Approach, Meghan Elizabeth Mooney 2015 University of Denver

Pedestrian Mobility In Denver: A Mixed Methods Approach, Meghan Elizabeth Mooney

Electronic Theses and Dissertations

This research is rooted in the bigger issues of climate change, urban sustainability, and the drive to make Denver more pedestrian centered despite sprawled conditions. More specifically, this research is driven by (1) the need for a holistic, multi-dimensional, and mixed geographic perspective of pedestrian mobility, (2) the lack of qualitative data regarding pedestrian mobility and (3) a need for a better understanding of the feedback between physical and perceived space and how this influences walking behavior. Given these motivations, I deploy a multidimensional framework for assessing pedestrian mobility in Denver’s Transit Oriented Development (TOD) sites, whereby there are two …

Theses, Dissertations and Capstones

Appalachia needs a way to sustainably develop. Cannabis Sativa L. may be a possible source of sustainable development for West Virginia. The goal of this study is the identification of possible sites for industrial hemp fiber cultivation areas, both the total agricultural potential and with current land use land cover classification limits, and which of these sites have the potential for acid mine drainage phytoremediation.

Using LUCIS classification and binary analysis, three major separate outputs were created answering the three study questions. The agricultural layer revealed that West Virginia can utilize hemp farming for 23.48% of the state. The second …


The Relationship Between Particle Travel Distance And Channel Morphology: Results Fromphysicalmodels Of Braided Rivers, Alan Kasprak, Joseph Wheaton, Peter Ashmore, James Hensleigh, Sarah Peirce 2015 Utah State University

The Relationship Between Particle Travel Distance And Channel Morphology: Results Fromphysicalmodels Of Braided Rivers, Alan Kasprak, Joseph Wheaton, Peter Ashmore, James Hensleigh, Sarah Peirce

Geography & Environment Publications

Channel form and sediment transport are closely linked in alluvial rivers, and as such the development of a conceptual framework for the downstream controls on particle mobility and likely deposition sites has immense value in terms of the way we understand and predictively model rivers. Despite the development of conceptual models which frame flood-scale particle transport distance (termed path length) as a function of channel bar locations, an understanding of the controls on such path lengths in braided rivers remains especially elusive, in large part due to the difficulty in explicitly linking morphology and particle transport distances in the field. …

Human Consequences Of Climate Change, Climate Refugees: An Exploratory Essay, Frederick A. Snyder-Manetti

Graduate Student Theses, Dissertations, & Professional Papers

While planning my course schedule for the 2009 Spring Semester, I found myself desperately short of elective credits toward my Bachelor of Arts degree in Geography in order to graduate by the end of the 2010 Autumn Semester. From the limited course choices offered for the spring semester, only two worked with the other required courses I needed as well: Cultural & Global Competence and Global Hot Spots. Little did I know at the time, but the latter would prove to be the most stimulating course of my entire undergraduate geography program. Not only did this course forge within me …


Quantifying The Interaction Of Wildlife And Roads: A Habitat And Movement Approach, Rebecca Whitehead Loraamm 2015 University of South Florida

Quantifying The Interaction Of Wildlife And Roads: A Habitat And Movement Approach, Rebecca Whitehead Loraamm

USF Tampa Graduate Theses and Dissertations

There is a growing need to address the effects of roadway presence on wildlife. Not only do roads directly impact gene dispersal from a movement perspective, but they limit movement of the individual animal from a habitat perspective by presenting an artificial barrier between one area of viable habitat and another. For this reason it is becoming increasingly important to quantify contact between humans and wildlife and to develop better methods for mitigating these types of conflicts. Studying habitat connectivity and animal mobility in the context of roads can provide actionable information on how, where, and when these encounters might …


The Biogeography And Diversity Of Termites In Southern Africa, Brianna Lind 2015 South Dakota State University

The Biogeography And Diversity Of Termites In Southern Africa, Brianna Lind

Electronic Theses and Dissertations

Termites (Blattodea: Termitoidae) are socially complex insects that are morphologically diverse and live in colonies. They represent a highly specialized form of cockroach that organizes into castes (distinct social groups including workers, soldiers, queen, etc.) that have specific roles within the colony (Eggleton 2010). Globally more than 2,600 species of termites have been described in over 280 genera and, while termites can occur in most climatic zones warmer than tundra, their greatest abundance and ecological significance is in the tropics (Kambhampti and Eggleton 2000). Termites impact many processes, including nutrient cycling, water dynamics, and soil porosity; in African savannas it …


Snow Cover Variability In A Forest Ecotone Of The Oregon Cascades Via Modis Terra Products, Tihomir Sabinov Kostadinov, Todd R. Lookingbill 2015 University of Richmond

Snow Cover Variability In A Forest Ecotone Of The Oregon Cascades Via Modis Terra Products, Tihomir Sabinov Kostadinov, Todd R. Lookingbill

Geography and the Environment Faculty Publications

Snowcover pattern and persistence have important implications for planetary energy balance, climate sensitivity to forcings, and vegetation structure, function, and composition. Variability in snow cover within mountainous regions of the Pacific Northwest, USA is attributable to a combination of anthropogenic climate change and climate oscillations. However, snowcovered areas can be heterogeneous and patchy, requiring more detailed mapping of snow trends to understand their potential influences on montane forests. We used standard dailyMODIS snow products (MOD10A1.5) to investigate the 15-year record (2000–2014) of snow cover in the predominant forest ecotone of the Oregon Western Cascades. We modeled the ecotone using field …


Overcoming Uncertainty And Barriers To Adoption Of Blue-Green Infrastructure For Urban Flood Risk Management, Colin R. Thorne, E. C. Lawson, Connie P. Ozawa, Samantha Hamlin, Leonard A. Smith 2015 University of Nottingham

Overcoming Uncertainty And Barriers To Adoption Of Blue-Green Infrastructure For Urban Flood Risk Management, Colin R. Thorne, E. C. Lawson, Connie P. Ozawa, Samantha Hamlin, Leonard A. Smith

Urban Studies and Planning Faculty Publications and Presentations

Blue-Green Infrastructure (BGI) and Sustainable Drainage Systems (SuDS) are increasingly recognised as vital components of urban flood risk management. However, uncertainty regarding their hydrologic performance and lack of confidence concerning their public acceptability create concerns and challenges that limit their widespread adoption. This paper investigates barriers to implementation of BGI in Portland, Oregon, using the Relevant Dominant Uncertainty (RDU) approach. Two types of RDU are identified: scientific RDUs related to physical processes that affect infrastructure performance and service provision, and socio-political RDUs that reflect a lack of confidence in socio-political structures and public preferences for BGI. We find that socio-political …

Changing States: Using State-And-Transition Models To Evaluate Channel Evolution Following Dam Removal Along The Clark Fork River, Montana, Christopher Van Dyke 2015 University of Kentucky

Changing States: Using State-And-Transition Models To Evaluate Channel Evolution Following Dam Removal Along The Clark Fork River, Montana, Christopher Van Dyke

Theses and Dissertations--Geography

Located just east of Missoula, Montana, Milltown Dam stood from 1908 to 2008 immediately downstream of the Clark Fork River’s confluence with the Blackfoot River. After the discovery of arsenic-contaminated groundwater in the nearby community of Milltown, as well as extensive deposits of contaminated sediment in the dam’s upstream reservoir, in 1981, the area was designated a Superfund site – along with much of the Upper Clark Fork Watershed. This motivated the eventual decision to remove the dam, perform environmental remediation, and reconstruct approximately five kilometers of the Clark Fork River and its floodplain. This study is part conceptual and …


Behavioral Response Of Pacific Lamprey (Entosphenus Tridentatus) To Predator Odors, Laurie L. Porter 2015 Central Washington University

Behavioral Response Of Pacific Lamprey (Entosphenus Tridentatus) To Predator Odors, Laurie L. Porter

All Master's Theses

Pacific lamprey (Entosphenus tridentatus), a species facing serious threats to their existence, experience a number of challenges in reaching their desired spawning grounds during the adult migratory phase, and predators are suspected to be one of these challenges. Understanding if Pacific lamprey respond to predator odorants may provide a management tool for use in conjunction with attractants in guiding lamprey to suitable spawning habitat and deterring them from poor habitat. Previous research has failed to explore Pacific lamprey response to predator odorants, although much research exists on attractant odorants. In our study, we tested Pacific lamprey response to …


Examining The Spatial Aspects Of Residential Energy Efficiency: Gis And Survey Analysis In Boulder County, Colorado, Walter Stanley Scheib 2015 University of Denver

Examining The Spatial Aspects Of Residential Energy Efficiency: Gis And Survey Analysis In Boulder County, Colorado, Walter Stanley Scheib

Electronic Theses and Dissertations

The completion of residential energy efficiency upgrades leads to multifaceted benefits including cost and energy savings, increased household comfort, health benefits, and reduced CO2 emissions. As a result of these benefits, state and local energy efficiency programs across the United States are striving to increase the widespread adoption of energy efficiency upgrades by homeowners. Many program strategies for widespread adoption are informed by case studies of other successful energy efficiency programs. These program strategies would benefit from the additional insight provided by spatial analysis, but a spatial perspective is currently underutilized by energy efficiency programs across the United States. This …
