Nonlinear Reaction–Diffusion Process Models Improve Inference For Population Dynamics, Xinyi Lu, Perry J. Williams, Mevin B. Hooten, James A. Powell, Jamie N. Womble, Michael R. Bower 2019 Colorado State University, Fort Collins

Nonlinear Reaction–Diffusion Process Models Improve Inference For Population Dynamics, Xinyi Lu, Perry J. Williams, Mevin B. Hooten, James A. Powell, Jamie N. Womble, Michael R. Bower

United States National Park Service: Publications

Partial differential equations (PDEs) are a useful tool for modeling spatiotemporal dynamics of ecological processes. However, as an ecological process evolves, we need statistical models that can adapt to changing dynamics as new data are collected. We developed a model that combines an ecological diffusion equation and logistic growth to characterize colonization processes of a population that establishes long-term equilibrium over a heterogeneous environment. We also developed a homogenization strategy to statistically upscale the PDE for faster computation and adopted a hierarchical framework to accommodate multiple data sources collected at different spatial scales. We highlighted the advantages of using a …

Air pollution is reported as one of the most severe environmental problems in the Middle East and North Africa (MENA) region. Remotely sensed data from newly available TROPOMI - TROPOspheric Monitoring Instrument on board Sentinel-5 Precursor, shows an annual mean of high-resolution maps of selected air quality indicators (NO2, CO, O3, and UVAI) of the MENA countries for the first time. The correlation analysis among the aforementioned indicators show the coherency of the air pollutants in urban areas. Multi-year data from the Aerosol Robotic Network (AERONET) stations from nine MENA countries are utilized here to study the aerosol optical depth …


Benefit Sharing In The Arctic: A Systematic View, Andrey Petrov, Maria S. Tysiachniouk 2019 University of Northern Iowa

Benefit Sharing In The Arctic: A Systematic View, Andrey Petrov, Maria S. Tysiachniouk

Faculty Work

Benefit sharing is a key concept for sustainable development in communities affected by the extractive industry. In the Arctic, where extractive activities have been growing, a comprehensive and systematic understanding of benefit sharing frameworks is especially critical. The goal of this paper is to develop a synthesis and advance the theory of benefit sharing frameworks in the Arctic. Based on previously published research, a review of literature, a desktop analysis of national legislation, as well as by capitalizing on the original case studies, this paper analyzes benefit sharing arrangements and develops the typology of benefit sharing regimes in the Arctic. …


The Cost Of The Culturati: Studying The Neighborhood Stability Impact Of Cultural District Designations, Prakash Mishra 2019 University of Pennsylvania

The Cost Of The Culturati: Studying The Neighborhood Stability Impact Of Cultural District Designations, Prakash Mishra

Dartmouth Undergraduate Journal of Politics, Economics and World Affairs

The decision to declare a district for a specific cause is a critical policy decision; making an area an official office park or designated cultural site means it will attract specific types of residents and businesses and require specific amenities. This paper reviews the impact of designating a cultural district as a place-based policy, specifically by developing a measure of neighborhood stability and applying a stress test of neighborhood stability in cultural districts during the Great Recession. The model underpining the neighborhood stability measure is an optimal stopping time model which frames neighborhood rents as a Brownian motion with drift. …

Permafrost Hydrology Drives The Assimilation Of Old Carbon By Stream Food Webs In The Arctic, Jonathan A. O’Donnell, Michael P. Carey, Joshua C. Koch, Xiaomei Xu, Brett A. Poulin, Jennifer Walker, Christian E. Zimmerman 2019 National Park Service, Arctic Network

Permafrost Hydrology Drives The Assimilation Of Old Carbon By Stream Food Webs In The Arctic, Jonathan A. O’Donnell, Michael P. Carey, Joshua C. Koch, Xiaomei Xu, Brett A. Poulin, Jennifer Walker, Christian E. Zimmerman

United States National Park Service: Publications

Permafrost thaw in the Arctic is mobilizing old carbon (C) from soils to aquatic ecosystems and the atmosphere. Little is known, however, about the assimilation of old C by aquatic food webs in Arctic watersheds. Here, we used C isotopes (d13C, D14C) to quantify C assimilation by biota across 12 streams in arctic Alaska. Streams spanned watersheds with varying permafrost hydrology, from ice-poor bedrock to ice-rich loess (that is, yedoma). We measured isotopic content of (1) C sources including dissolved organic C (DOC), dissolved inorganic C (DIC), and soil C, and (2) stream biota, including benthic biofilm and macroinvertebrates, and …


Free And Open Source Gis In South America: Political Inroads And Local Advocacy, Sterling Quinn 2019 Central Washington University

Free And Open Source Gis In South America: Political Inroads And Local Advocacy, Sterling Quinn

All Faculty Scholarship for the College of the Sciences

Geographical information systems (GIS) practitioners worldwide enjoy a growing array of free and open source software (FOSS) options. This software has expanded the accessibility of GIS in economically developing countries while fostering local technical expertise. This article reviews FOSS GIS uptake and advocacy in South America, especially how it relates to a climate of political friendliness toward FOSS in the region. The use or absence of FOSS GIS is assessed in public-facing web maps in South America, first at the national government level, and then at the provincial level using Argentina as a country of study. Local technical support groups …


A Least Cost Analysis: Correlative Modeling Of The Chaco Regional Road System, Sean Field, Carrie Heitman, Heather Richards-Rissetto 2019 University of Notre Dame

A Least Cost Analysis: Correlative Modeling Of The Chaco Regional Road System, Sean Field, Carrie Heitman, Heather Richards-Rissetto

Department of Anthropology: Faculty Publications

During the ninth through twelfth centuries A.D., Ancestral Pueblo people constructed long, straight roads that interconnected the Chaco regional system across the San Juan Basin of northwestern New Mexico. The intent and use of these features has eluded archaeological consensus, although recent research has reiterated the occurrence of long distance timber importation to Chaco Canyon. To enhance our interpretation of these features we offer a large-scale least cost analysis wherein optimal pathways that are modeled to simulate timber importation are compared to the actual road locations. A series of least cost paths were produced through different energy allocation algorithms, at …


Virtual Audits Of Streetscapes By Crowdworkers, Tomoya Hanibuchi, Tomoki Nakaya, Shigeru Inoue 2019 Portland State University

Virtual Audits Of Streetscapes By Crowdworkers, Tomoya Hanibuchi, Tomoki Nakaya, Shigeru Inoue

Geography Faculty Publications and Presentations

Audits have been used to provide objective ratings of neighborhood environments. Physical audits, however, are time- and resource-intensive. This study examines the efficiency and reliability of virtual auditing using Google Street View and crowdsourcing to conduct walkability audits of streets in Japan. Overall, 830 street segments were physically and virtually audited by two trained auditors; 300 untrained crowdworkers also virtually audited 3 street segments. Statistical analysis found good inter-source and inter-rater reliability. This study helps establish crowdsourced virtual auditing as a valuable method of measuring neighborhood walkability, reducing audit costs as well as enabling large-scale auditor recruitment while maintaining reliability.


Rock Glaciers Of The Beartooth And Northern Absaroka Ranges, Montana, Usa, Zachary M. Seligman, Anna E. Klene, Frederick E. Nelson 2019 University of Montana, Missoula

Rock Glaciers Of The Beartooth And Northern Absaroka Ranges, Montana, Usa, Zachary M. Seligman, Anna E. Klene, Frederick E. Nelson

Geography Faculty Publications

Six hundred sixty‐one rock glaciers in the northern Absaroka and Beartooth Ranges of south‐central Montana were digitized and evaluated using geographic information systems technology and an array of topographic and environmental parameters. Beartooth rock glaciers are larger, occur at higher elevations, receive more precipitation, and are subject to lower temperatures than northern Absaroka rock glaciers. Elevation is strongly correlated with rock glacier activity. Comparative analysis of these adjacent mountain ranges indicates that Beartooth geomorphic landscapes are shifting from predominantly glacial to periglacial regimes, and that the northern Absarokas have largely completed this transition. Because glaciers are declining in response to …


Sedimenting Territory: A Political Geology Of Oil, Earth, And Spatial Politics In Turkey, Zeynep Oguz 2019 CUNY Graduate Center

Sedimenting Territory: A Political Geology Of Oil, Earth, And Spatial Politics In Turkey, Zeynep Oguz

Dissertations, Theses, and Capstone Projects

Building on the recent turn to the material and earthly aspects of resources and political power in environmental anthropology and political geography, this work historically and ethnographically examines the kinds of territorial politics that oil’s materiality, geological qualities, and infrastructures have generated in Turkey. Despite being surrounded by oil-rich neighbors in the Middle East, Turkey’s domestic oil reserves supply only 7 percent of the country’s oil, all of which has been drilled in the Kurdish provinces of Batman, Diyarbakır, and Adıyaman in Turkey’s southeast, where the PKK (Kurdistan Workers’ Party) has been fighting the Turkish state since 1984 for cultural …


Signals In The Black Stack / Geometyr Design Manual, Jason T. Scaglione 2019 CUNY Graduate Center

Signals In The Black Stack / Geometyr Design Manual, Jason T. Scaglione

Dissertations, Theses, and Capstone Projects

The following white paper provides a critical accompaniment to my capstone project: the GEOMEtyr Design Manual. GEOMEtyr is a virtual reality to be made accessible as a mobile and web platform for the visualization of certain systemic elements of a utopic world that parallels our own planet’s geographies, polities, and climates. As such, the GEOMEtyr virtualization is designed to derive utopian space from the informational structures of our own world. The operations by which this may be accomplished are broadly described within the accompanying GEOMEtyr manual. The white paper, Signals in the Black Stack, elaborates vital world-building characteristics of informational …


Market Making: Crises And The Global Production Of Shipbreaking In Chittagong, Bangladesh, Elizabeth A. Sibilia 2019 CUNY Graduate Center

Market Making: Crises And The Global Production Of Shipbreaking In Chittagong, Bangladesh, Elizabeth A. Sibilia

Dissertations, Theses, and Capstone Projects

Shipbreaking is a dismantling process with a primary objective of extracting large amounts of steel from ocean-going vessels, oil tankers, bulk cargo carriers, and container ships. As mobile forms of fixed capital, these devalued vessels have experienced a gradual or sudden loss of value. The removal of devalued ships from the world fleet, through an increasingly sophisticated global demolition market and expanding domestic shipbreaking markets, have played a critical role in helping the global shipping sector solve its crises of overproduction since the mid 1970s. Since the early 1990s Bangladesh has become one of the most important domestic shipbreaking markets. …


Rails To Revolution: Railroads, Railroad Workers And The Geographies Of The Mexican Revolution, Hector Agredano 2019 CUNY Graduate Center

Rails To Revolution: Railroads, Railroad Workers And The Geographies Of The Mexican Revolution, Hector Agredano

Dissertations, Theses, and Capstone Projects

This dissertation is a historical geography of the role of railroads and railroad workers in the Mexican Revolution. It shows that despite the presence of railroads in the popular imagination of the Mexican Revolution, the role of railroads and railroad workers themselves remains largely missing from scholarly accounts of the conflict. I argue that railroad workers were central to the revolutionary process from its beginning, and I demonstrate that their close relationship to a critically important transportation network allowed them to intervene at crucial moments of the revolutionary process. Undoubtedly, this relationship to transportation networks also had a formative impact …


Runaway: A History Of Postwar New York In Four Factories, Andy Battle 2019 CUNY Graduate Center

Runaway: A History Of Postwar New York In Four Factories, Andy Battle

Dissertations, Theses, and Capstone Projects

At midcentury, New York City was among the preeminent manufacturing centers in the United States. Within a generation, this manufacturing economy suffered an extraordinary collapse. Beginning in the 1950s, workers and their unions began to use the term “runaway” to describe factories that pulled up stakes in New York and set them back down in other climes. This dissertation explores the deindustrialization of New York City through case studies of “runaway” plants, or factories that left New York for the American South or abroad between the years 1945 and 1975.

In general, the manufacturers that remained in New York at …
