Building A Better Model: Variable Selection To Predict Poverty In Pakistan And Sri Lanka, Marium Afzal, Jonathan Hersh, David Newhouse

Economics Faculty Articles and Research

Numerous studies have developed models to predict poverty, but surprisingly few have rigorously examined different approaches to developing prediction models. This paper applies out of sample validation techniques to household data from Pakistan and Sri Lanka, to compare the accuracy of regional poverty predictions from models derived using manual selection, stepwise regression, and Lasso-based procedures. It also examines how much incorporating publically available satellite data into the model improves its accuracy. The five main findings are that: 1) Lasso tends to outperform both discretionary and stepwise models in Pakistan, where the set of potential predictors is large. 2) Lasso and …

A Geospatial Tool For Wetland Prioritization At The Watershed Scale, Debra Sue Blackmore, Heejun Chang

Institute for Natural Resources Publications

There is an increasing demand for assessing ecosystem functions for freshwater wetlands, especially when comparing or prioritizing among wetlands at the watershed scale. We estimated the relative potential of selected ecosystem functions for freshwater wetlands within a watershed using widely available geospatial data. We developed four functions to estimate 1) flood storage, 2) late season flow, 3) sediment retention and 4) temperature control in four pilot watersheds in Oregon (Tualatin, Coquille, Upper Grande Ronde and Sprague). These watersheds are geographically separated from each other representing diverse ecoregion environments. Spatial analysis and geographic information system (GIS) were designed for maximum re-use, …

Late Quaternary Speleogenesis And Landscape Evolution In A Tropical Carbonate Island: Pango La Kuumbi (Kuumbi Cave), Zanzibar, Nikos Kourampas, Ceri Shipton, William Mills, Ruth Tibesasa, Henrietta Horton, Mark Horton, Mary Prendergast, Alison Crowther, Katerina Douka, Patrick Faulkner, Llorenç Picornell, Nicole Boivin

International Journal of Speleology

Kuumbi Cave is one of a group of caves that underlie a flight of marine terraces in Pleistocene limestone in eastern Zanzibar (Indian Ocean). Drawing on the findings of geoarchaeological field survey and archaeological excavation, we discuss the formation and evolution of Kuumbi Cave and its wider littoral landscape. In the later part of the Quaternary (last ca. 250,000 years?), speleogenesis and terrace formation were driven by the interplay between glacioeustatic sea level change and crustal uplift at rates of ca. 0.10-0.20 mm/yr. Two units of backreef/reef limestone were deposited during ‘optimal’ (highest) highstands, tentatively correlated with MIS 7 and …

Brushfire, Ariel Gordon

The Goose

“Brushfire” concerns itself with how people use urban forests, from indecent exposure to poaching to teenage drinking party-bonfires that get out of control. Though it could be construed as a manifesto on walking-in-the-woods, it also touches on some of the conflicts inherent in urban/nature experiences.

Spatiotemporal Wireless Sensor Network Field Approximation With Multilayer Perceptron Artificial Neural Network Models, François Neville

Electronic Theses and Dissertations

As sensors become increasingly compact and dependable in natural environments, spatially-distributed heterogeneous sensor network systems steadily become more pervasive. However, any environmental monitoring system must account for potential data loss due to a variety of natural and technological causes. Modeling a natural spatial region can be problematic due to spatial nonstationarities in environmental variables, and as particular regions may be subject to specific influences at different spatial scales. Relationships between processes within these regions are often ephemeral, so models designed to represent them cannot remain static. Integrating temporal factors into this model engenders further complexity.

The Innovation Makerspace: Geographies Of Digital Fabrication Innovation In Greater New York City, Kathryn Dickerson

Theses and Dissertations

Desktop digital fabrication technology has the potential to powerfully alter the economics, geography, and sociology of production. The desktop technology cannot reach its potential for widespread impact until it improves in quality and decreases in price. Makerspaces have emerged in the United States in the last eight years as informal social organizations where innovation in this technology may be occurring. This study examines whether innovation in digital fabrication technology has occurred, or has the potential to occur, at makerspaces in the New York City area.

Quantifying Undisturbed Land In Minnesota's Prairie Coteau And Lac Qui Parle Valley Regions, Pete Bauman, Ben Carlson, Tanner Butler

Quantifying Undisturbed Lands in MInnesota's Prairie Coteau and Lac qui Parle Valley Regions

We employed simple GIS methods utilizing the Minnesota Farm Service Agency’s Common Land Unit (CLU) cropland data layer from 2013, along with 2013 USDA National Agriculture Imagery Program (NAIP) county mosaic aerial imagery, to evaluate over 5 million acres of land in 14 southwest Minnesota counties, including all or portions of 10 counties within the Minnesota portion of the Prairie Coteau region and the entirety of four counties in the Lac qui Parle region. We utilized the CLU cropland layer to first identify and remove any areas with a cropping history, regardless of current land use. We then analyzed the …

A Modeling Approach To Determine The Impacts Of Land Use And Climate Change Scenarios On The Water Flux Of The Upper Mara River, L. M. Mango, Assefa Melesse, M. E. Mcclain, Daniel Gann, S. G. Setegn

Daniel Gann

With the flow of the Mara River becoming increasingly erratic especially in the upper reaches, attention has been directed to land use change as the major cause of this problem. The semi-distributed hydrological model Soil and Water Assessment Tool 5 (SWAT) and Landsat imagery were utilized in the upper Mara River Basin in order to 1) map existing field scale land use practices in order to determine their impact 2) determine the impacts of land use change on water flux; and 3) determine the impacts of rainfall (0%, ±10% and ±20%) and air temperature variations (0% and +5%) based on …

Relationship Between Household Food Insecurity And Health In The Upper West Region Of Ghana, Kilian Nasung Atuoye

Electronic Thesis and Dissertation Repository

Although the importance of food as a social determinant of health has been elucidated, it remains underexplored in Sub-Saharan Africa (SSA), where a significant population is faced with challenges of accessing food, largely from a combination many factors including low economic power, poor livelihoods, political instability and policy gaps. Despite tremendous improvement on food security in Ghana, the northern part of the country including the Upper West Region still experience disproportionally high levels of deprivation and food insecurity. Research has tends to explain the dynamics and complexities of food insecurity in the Region, yet variation of the incidence of food …

Quantitative Comparison Of Plant Community Hydrology Using Large-Extent, Long-Term Data, Daniel Gann, Jennifer H. Richards

Daniel Gann

Large-extent vegetation datasets that co-occur with long-term hydrology data provide new ways to develop biologically meaningful hydrologic variables and to determine plant community responses to hydrology. We analyzed the suitability of different hydrological variables to predict vegetation in two water conservation areas (WCAs) in the Florida Everglades, USA, and developed metrics to define realized hydrologic optima and tolerances. Using vegetation data spatially co-located with long-term hydrological records, we evaluated seven variables describing water depth, hydroperiod length, and number of wet/dry events; each variable was tested for 2-, 4- and 10-year intervals for Julian annual averages and environmentally-defined hydrologic intervals. Maximum …

Evaluating High-Resolution Aerial Photography Acquired By Unmanned Aerial Systems For Use In Mapping Everglades Wetland Plant Associations, Daniel Gann, Jennifer H. Richards

Daniel Gann

Mapping of vegetation patterns over large extents using remote sensing methods requires field sample collections for two different purposes: (1) the establishment of plant association classification systems from samples of relative abundance estimates; and (2) training for supervised image classification and accuracy assessment of satellite data derived maps. One challenge for both procedures is the establishment of confidence in results and the analysis across multiple spatial scales. Continuous data sets that enable cross-scale studies are very time consuming and expensive to acquire and such extensive field sampling can be invasive. The use of high resolution aerial photography (hrAP) offers an …
