Social Organization And Environmental Patterning At Tel Abu Shusha: An Integrated Spatial Approach To Survey Archaeology, Seth Price

Graduate Theses and Dissertations

Tel Abu Shusha, located in the Jezreel Valley of Palestine, is a large-scale archaeological site possibly identified as the cities of Biblical Gaba or Roman Gaba Hippaeon/Gaba Philippi. Surface archaeological survey of the surrounding area, conducted by the Jezreel Valley Regional Project during 2017, revealed extensive assemblages of visible settlement features dating primarily to middle and late Islamic periods. This research seeks to answer questions of settlement decision-making and societal organization, by integrating archaeological, textual, environmental, and geospatial data sources. In addition to visual interpretation, Kolmogorov-Smirnov nonparametric tests are used to gain insight on environmental settlement preferences; Ripley’s K analysis …

Poverty Mapping Using Convolutional Neural Networks Trained On High And Medium Resolution Satellite Images, With An Application In Mexico, Boris Babenko, Jonathan Hersh, David Newhouse, Anusha Ramakrishnan, Tom Swartz

Economics Faculty Articles and Research

Mapping the spatial distribution of poverty in developing countries remains an important and costly challenge. These “poverty maps” are key inputs for poverty targeting, public goods provision, political accountability, and impact evaluation, that are all the more important given the geographic dispersion of the remaining bottom billion severely poor individuals. In this paper we train Convolutional Neural Networks (CNNs) to estimate poverty directly from high and medium resolution satellite images. We use both Planet and Digital Globe imagery with spatial resolutions of 3-5 m2 and 50 cm2 respectively, covering all 2 million km2 of Mexico. Benchmark poverty estimates come from …

Towards New Weather And Climate Baselines For Assessing Weather And Climate Extremes, Impacts, And Risks, Fiona Williamson, Rob Allan, Roseanne D'Arrigo

Research Collection College of Integrative Studies

Initiatives to recover (sourcing, imaging, digitizing) historic datasets for generating more accurate longterm climate models have only gained momentum over the last decade, despite a long precedent of compelling arguments as to the value of historic weather observations (Le Roy Ladurie, 1972; Lamb, 1977). Although such work is relatively well established in Europe, the United States, China, and Japan; Southeast Asia currently has a dearth of data rescue initiatives with a long historical focus. The reasons behind this include a perception of the paucity of surviving data; the scattered nature of data due to shifts between colonial rule and independence …

Proxy Dating In Iceland Testing The Validity Of Silene Acaulis As A Phytometric Proxy, Madelyn Grant

Independent Study Project (ISP) Collection

Climate change is causing drastic changes in the cryosphere, particularly in the Arctic region where average warming is 1.9 times greater than in the rest of the world due to Arctic amplification. Understanding the response of essential climate variables such as glaciers and ice caps to rapid Arctic warming is essential to predicting future changes in the Arctic region and around the world. Proxy dating methods can help construct a record of warming-induced glacial retreat in areas where long-term monitoring systems are not in place. In Arctic regions, the cushion plant Silene acaulis represents one of the only feasible proxies …

Trade And Transport In Late Roman Syria, Christopher Wade Fletcher May 2016

Trade And Transport In Late Roman Syria, Christopher Wade Fletcher

Graduate Theses and Dissertations

Despite the relative notoriety and miraculous level of preservation of the Dead Cities of Syria, fundamental questions of economic and subsistence viability remain unanswered. In the 1950s Georges Tchalenko theorized that these sites relied on intensive olive monoculture to mass export olive oil to urban centers. Later excavations discovered widespread cultivation of grains, fruit, and beans which directly contradicted Tchalenko’s assertion of sole reliance on oleoculture. However, innumerable olive presses in and around the Dead Cities still speak to a strong tradition of olive production. This thesis tests the logistical viability of olive oil transportation from the Dead Cities to …


Building A Better Model: Variable Selection To Predict Poverty In Pakistan And Sri Lanka, Marium Afzal, Jonathan Hersh, David Newhouse Sep 2015

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 Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz Jan 2015

A Gis Assessment Of Ecoregion Representation In Chile's Existing And Proposed Integrated Network Of Protected Areas, Jessica Schutz

Graduate Student Theses, Dissertations, & Professional Papers

Chile's state designated protected areas are reported to show representation bias and to be unable to meet conservation goals. Private protected areas are considered an important tool to resolve these issues, which has led to support for increasing the role of private protected areas in Chile and creating an integrated public-private protected area network. But the validity of the capacity of private protected areas to fix Chile's state protected area network bias, and the advantage of creating an integrated protected area network, have not been assessed. This study uses the most recent data on Chile's state, private, and international protected …

The Myths Of G-Tech For Business Decision Making, Tin Seong Kam

Research Collection School Of Computing and Information Systems

More than 80% of organisation data are location related - the locations where transactions are done, where retailers are found, and of customers who buy their products. Since the early 2005, there has been an increasing interest among the business community to use geospatial technology to enhance decision making process at both strategic and operational levels. Millions of dollars and man-hours have been invested into driving their geo-technology development and implementation. The use of geospatial technology in business, however, tends to confine to simple mapping. Many of these failures are the victims of misperception. Some of the perpetrators are practitioners. …


Understanding Colombian Violence Through Geographic Information Systems And Statistical Approaches, Brandon Fowler May 2013

Understanding Colombian Violence Through Geographic Information Systems And Statistical Approaches, Brandon Fowler

Masters Theses & Specialist Projects

In 2002, Colombia had the highest homicide rate of any Latin American country(Berkman, 2007). The origins of this violence, however, are complex and difficult to identify. It would be sensible to argue that it cannot be explained by any one particular factor, but rather an assortment of many factors that wholly represent the social, economic, and political conditions of Colombia. By better understanding the origins of Colombian violence, policy makers can more effectively address and alleviate this prolonged issue. This study examines the geographic nature of municipal homicide rates for Colombia in 2005. The purpose of this study is to …


Mapping Xenophobic Violence In South Africa: Modeling Spatial Relationships Between Group Grievances And Opportunities To Measure The Propensity For Xenophobic Violence, Eric Holder Dec 2012

Mapping Xenophobic Violence In South Africa: Modeling Spatial Relationships Between Group Grievances And Opportunities To Measure The Propensity For Xenophobic Violence, Eric Holder

Graduate Theses and Dissertations

Xenophobia can be defined as the hatred or fear of foreigners or strangers or of their politics or culture (Ngwane et al., 2008). This sentiment reached its tipping point in urban areas across the Republic of South Africa in May 2008 when mass, widespread and systematic attacks against African non-nationals took place across the country. Although previous research agrees on who played the various roles during this crisis event (Everatt, 2010), little research has been carried out to create a predictive model to assess where future violence could occur based on a set of conflict indicators. The purpose of this …

This study is a geographic analysis of HIV/AIDS infection in Nigeria from 1991 – 2001. The three objectives of this study were: 1) to examine the geographic pattern of the epidemic, 2) to examine the spatial-temporal trend and diffusion pattern of the epidemic, and 3) to explore the factors associated with the spatial …


Prospects For An International Charter "Space And Major Disaster" Remote Sensing Response To Drought Disasters - An Anhui, China Case Study, Joseph Burkhead Apr 2012

Prospects For An International Charter "Space And Major Disaster" Remote Sensing Response To Drought Disasters - An Anhui, China Case Study, Joseph Burkhead

Masters Theses

Remote sensing is often leveraged during the response phase of disaster management to improve the situational awareness of decision-makers. The International Charter "Space and Major Disaster" (Charter) provides remote sensing support to non-spacefaring nations facing disasters such as earthquakes, floods and tsunamis. However, the Charter has never activated for a major drought disaster. Since droughts affect over half of the nearly 3 billion people that suffer from natural disasters annually, this study seeks to determine whether satellite remote sensing can be effectively employed according to the intent, capabilities, and limitations of the Charter to benefit officials responding to a major …
