An 'Answer To Hopes And Dreams': Utopianism, Progressivism, And The American Spatial Tradition In The New Deal Resettlement Community Of Greenhills, Ohio, Jared M. Berg

Senior Independent Study Theses

The purpose of this project is to explain what historical forces led to the construction of Greenhills, Ohio. The goal is to show that Greenhills is one example in a very long line of planned residential communities in American history which have been designed in order to solve contemporary societal issues. This has been done by examining how Americans have constructed space in preceding planned communities. Upon examining these examples, it is clear that Greenhills is very much part of what I identify as an American spatial tradition, a community which especially borrows from the utopian and progressive elements of …

Experimental Evaluation Of Several Key Factors Affecting Root Biomass Estimation By 1500 Mhz Ground-Penetrating Radar, John C. Bain, Frank P. Day, John R. Butnor

Biological Sciences Faculty Publications

Accurate quantification of coarse roots without disturbance represents a gap in our understanding of belowground ecology. Ground penetrating radar (GPR) has shown significant promise for coarse root detection and measurement, however root orientation relative to scanning transect direction, the difficulty identifying dead root mass, and the effects of root shadowing are all key factors affecting biomass estimation that require additional research. Specifically, many aspects of GPR applicability for coarse root measurement have not been tested with a full range of antenna frequencies. We tested the effects of multiple scanning directions, root crossover, and root versus soil moisture content in a …

Open / Close: Assimilating Immersive Spaces In Visual Communication, Anika Sarin

Theses and Dissertations

I am interested in two spaces obverse to each other: open and closed. An open space develops organically based on how people inhabit it. Interacting with an open space is a dynamic, sporadic, multisensory, immersive, and subjective experience. In such spaces, we are confronted with an alternative aesthetic, one that is in conflict with the seamlessness of a closed space. A closed space is anchored on definite variables like structure, use and boundaries. While interaction between people and space is important, the space is tightly controlled and interaction is designed. Through this thesis project, I present a method that metaphorically …

A Multiscale Assessment Of Wind Energy Resources And Suitability In The Russian Arctic, Narmina Iusubova

Dissertations and Theses @ UNI

Wind as a renewable and clean source of energy has begun to take a high position in the global dialog about energy production. Today, one of the big questions is to find the most suitable locations for wind farms, with the goal of achieving the highest rates of electricity production possible. In order to find most suitable places to build windfarms, we need to develop multifactor and multiscale dynamic models of windfarm suitability. The interest in the assessment of wind energy suitability in the Russian North regions comes from the expectation of the great potential of wind power in the …

Information Technology Approaches To Forest Management, Mary Snow, Richard Snow

Publications

The majority of the world’s forests occur where there is a dry season long enough to affect a seasonal change in the forest community. The seasonal forest may include evergreen, semi-deciduous, deciduous trees, or some combination of these. Local differences in soil or other site characteristics often determine which community persists. Since the seasonal forests exist where there is seasonal precipitation, the character of the forest is closely associated with the length of the rainy season. As the length of the rainy season decreases, the density of the canopy decreases. If the global climate system warms and prolonged drought gives …

Estimating Energy Fluxes And Evapotranspiration Of Corn And Soybean With An Unmanned Aircraft System In Ames, Iowa, Áthila Gevaerd Montibeller

Dissertations and Theses @ UNI

Evapotranspiration (ET) is a key hydrological variable and has been studies to plan irrigation schedule, understand surface-atmospheric interactions, assess crop sensitivity to droughts, etc. On top of that, ET is a proxy for evaluating water availability in trees canopies and assess soil moisture content. The recent advent of the Unmanned Aircraft Systems (UAS) has presented new opportunities and challenges in mapping ET at a much finer scale and under various atmospheric conditions. In this research, we integrate traditional remote sensing techniques with the novel UAS technology to estimate ET and surface energy fluxes for a corn and soybean field near …

The New North: Patents And Knowledge Economy Analysis In Alaska, Salma Zbeed

Dissertations and Theses @ UNI

In the last few years, Alaska's economy suffered as world oil prices plunged to very low levels, and the analysts predicting that Alaska output will continue to dwindle in the years to come. As a result of Alaska's dependence on oil economy, the state now faces a budget deficit. Modern economic development theories suggest searching for ways to manage northern frontiers. Investment in a knowledge –based economy seems to be new one of the appealing alternatives, and investing the human capacities is necessary. There is enough evidence from both central and peripheral regions that geographic proximity between the people and …

Characterization Of Ecological Water Stress In The U.S. Great Lakes Region Using A Geospatial Modeling Approach, Sara Alian

Dissertations, Master's Theses and Master's Reports

Anthropocentric water resources management affects aquatic habitats by changing streamflow regime. Understanding the impacts of water withdrawal from different sources and consumption by various economic sectors at different spatial and temporal scales is key to characterizing ecologically harmful streamflow disturbances. To this end, we developed a generic, integrative framework to characterize catchment scale water stress at annual and monthly time scales. The framework accounts for spatially cumulative consumptive and non-consumptive use impacts and associated changes in flow due to depletion and return flow along the stream network. Application of the framework to the U.S. Great Lakes Region indicates that a …

A Landscape Of Water And Waste: Heritage Legacies And Environmental Change In The Mesabi Iron Range, John Baeten

Dissertations, Master's Theses and Master's Reports

This dissertation explores the intersection between mining technology, industrial heritage, and environmental history, using iron mining in the Mesabi Range of the Lake Superior Iron District as its core case study. What impact did technological shifts in iron mining and ore processing have on the environment of the Lake Superior basin? How did the environmental changes wrought from low-grade iron ore mining and processing, such as the expansion of open-pits and the production of tailings, affect different communities in Minnesota’s Mesabi Range? And finally, how have the environmental legacies of iron mining been remembered and memorialized, or ignored and forgotten?

Marine Protected Areas In Colombia: Re-Connecting Social, Ecological, And Policy Aspects Through A Governance Perspective, Luisa Ramirez

Theses and Dissertations (Comprehensive)

The purpose of this doctoral research is to examine opportunities and constraints for integrating key aspects of governance into marine conservation strategies and for shifting top-down approaches toward collaborative and integrative forms of governance that enhance conservation and social outcomes in marine protected areas (MPAs).

Although there is evidence that demonstrates that MPAs are an effective tool for marine conservation, shortcomings in addressing ecological characteristics and particularly in addressing social factors in the design and planning of MPAs often constrain achieving conservation and sustainability goals. These shortcomings are particularly acute in MPAs implemented through top-down governance approaches that overlook stakeholder …

Newcomers, Welcome? Exploring The Connection Between Demographic Change, Immigration Legislation Design And Policy Mobilities In Ageing Japan, Héctor Goldar Perrote

Theses and Dissertations (Comprehensive)

Japan is ageing, and its population is declining. Given the potential detrimental economic and social consequences brought about by this sort of demographic change, it has been suggested that the Japanese could benefit from the implementation of more liberal (im)migration policies. This thesis studies the demographic change – immigration policy development nexus from the perspective of the state in the context of Japan and assesses the role that immigration plays within the larger population debate. A constructivist grounded theory methodology is utilised to analyse primary and secondary qualitative data. Additionally, two theoretical approaches of political demography (Robbins and Smith, 2016) …

The Political Ecology Of Water Justice: A Case Study Of Tripoli, Lebanon, Fatima Sidaoui

Theses and Dissertations (Comprehensive)

Despite the continuous efforts of the international community to address water scarcity, millions of people continue to lack access to safe drinking water and sanitation services. Water problems are often explained as natural phenomena or the result of technical failures, overlooking the fact that in many cases, water crises are those of socio-political inequalities rather than of scarcity. Examining water inequities, as political ecologists maintain, requires paying attention to the underlying power structures that perpetuate those injustices, and the agency available to people. My case study, located in Tripoli, Lebanon, attempts to understand those dynamics, specifically in relation to the …

Utilization Of Landsat Imagery To Assess The Impacts Of Oil And Gas Extraction On The Tazovsky Peninsula, Siberia, Nicholas B. Kline

Graduate Student Theses, Dissertations, & Professional Papers

Climatic warming of the Arctic is leading to landscape change through cascading biophysical feedbacks; development, such as oil and gas exploration and extraction, can accelerate or worsen these impacts. Due to restricted access to oil and natural gas fields, in situ environmental impact studies are only allowed in some regions. Satellite imagery analysis provides a mean for assessing impacts in areas with limited access. The Yamburg oil and gas field in western Siberia serves as a case study to assess the effects of infrastructure on an Arctic landscape.

This project quantifies the land-cover disturbance that occurred during the development and …

Flood Of Change: The Vanport Flood And Race Relations In Portland, Oregon, Michael James Hamberg

All Master's Theses

This thesis examines race relations amid dramatic social changes caused by the migration of African Americans and other Southerners into Portland, Oregon during World War II. The migrants lived in a housing project named Vanport and an exploration behind Portlanders’ negative opinion of newcomers will be undertaken. A history of African Americans in Oregon will open the paper and the analysis of events leading up to a 1948 flood that destroyed the housing project and resulted in a refugee and housing crisis will comprise the middle of the paper. Lastly, an examination of whether or not an improvement in race …

First Nations And Adaptive Water Governance In Southern Ontario, Canada, Thomas Dyck

Theses and Dissertations (Comprehensive)

Water quality and quantity are prominent concerns for First Nations across Canada. The federal government shares the responsibility with First Nations to ensure water resources on-reserves meet the needs of First Nations. Federal approaches have been predominantly technical, focused on addressing issues related to infrastructure, maintenance, training, and monitoring. This approach is important. However, water issues concerning First Nations go beyond technical issues and relate to inadequate participation in decision making, poorly defined roles and responsibilities, and approaches to managing water resources on-reserve that have not accounted for local context. These issues parallel historical nation-to-nation (i.e., First Nations and federal …
