The Emergence Of Ecosystems-Based Fisheries Management From The Groundfish Crisis In New England: An Actor-Network Theory Analysis, Catherine King

Dissertations, Theses, and Capstone Projects

This research investigates the emergence of ecosystems-based fisheries management (EBFM) for New England's marine fisheries in the context of the "crisis" that is escalating in its groundfish fishery. Close observations of the practices of fisheries scientists in coordination with managers at the New England Fisheries Management Council, with focus on how knowledge is being produced and employed, allows for understanding EBFM as an emergent construction produced by networks of associations between actants, human and non-human, material and semiotic, and not strictly as a policy prescription informed by experts on biology, ecology, and socio-economics. This analysis identifies and elucidates the multiplicity …

Oceanic Groundings: Maritime Geographies And Black Internationalism In The Early Twentieth Century, Maegan A. Miller

Dissertations, Theses, and Capstone Projects

This dissertation examines the shipboard writings, transnational solidarities and vernacular cultures, and spaces of social reproduction among Black and other subaltern seafarers and maritime travelers in the first decades of the twentieth century. I draw upon oral histories, literature, poetry, memoirs, and the archives of leftist political organizations and British colonial officials. Through a practice of close reading across textual genres and transnational spaces, my dissertation develops oceanic groundings as: (1) a constellation of iterative and intentional acts of political learning through the movements of ordinary people, (2) a pedagogical project of listening to and learning from the shifting grounds …

Data And Information As Our New Transport Infrastructure: An Exploration Into How The Modern Transport System Is Being Shaped By Information Communication Technology, Adam Davidson

Dissertations, Theses, and Capstone Projects

This dissertation is focuses on the role that data and information has in creating and altering behavior related to transportation. To do so, it lays out a theoretical model of technological transition and then follows it up with three case studies. The theoretical model provides a structure to consider how different actors in our transportation ecosystem – users, firms, policy actors – mix with technological evolution to uphold or incrementally recreate our transportation landscape. The case studies stand on their own to highlight important findings about how data and information are impacting transportation scenarios, but collectively reinforce the theoretical models. …

Legitimizing Violence At The European Border: Gendered Misrepresentations At Sea And The Vulnerable Other, Michela Demelas

Dissertations, Theses, and Capstone Projects

This thesis highlights a temporal and spatial gap in the feminist literature about migrants' journeys throughout the Mediterranean, and investigates the gendered dynamics acting upon the encounter between the European border and racialized bodies at sea. The Mediterranean sea’s material features allow Europe to approach migration as a humanitarian crisis coming from outside, which discharges its responsibility for the deaths. Yet, essentialistic views represent the feminized Other as vulnerable and needing to be saved from the male Other and the sea. Such views shape the Western narratives around concrete rescue procedures and border authorities behaviors. The encounter between the border …

A Defense And Expansion Of The Theory Of Capitalist Ground Rent: Speculation, Securitization, And Struggles Over Land And Housing, Francesca Manning

Dissertations, Theses, and Capstone Projects

Why are the rents so high? Who is responsible for homelessness, for urban and rural displacement? How can these problems be combatted?

Recent literature addressing these questions has pointed to gentrification and the financialization of land and housing, faulted financialized landlords, hedge funds, and the irredeemable logic of finance, and pointed to the importance of land and housing regulation to prevent displacement.

However, theories of displacement—in both land and housing, on both urban and rural terrain—suffer from a lack of an underlying theory of the logic, tendencies, and limits of ground rent extraction in capitalism.

This dissertation develops a theory …

Understanding The Support For Municipal Green Bin Programs, Oluwatomilola Ladele

Electronic Thesis and Dissertation Repository

As food waste increases globally, many cities have implemented curbside collection of food waste (aka green bin programs) to divert food waste from landfills. However, not all municipalities in Ontario have green bin programs. A factor responsible for the adoption of green bin programs is the community support for the program. The study results are based on 407 completed surveys from randomly selected households in London, Ontario (a municipality without a green bin program) and Kitchener-Waterloo, Ontario (a municipality with a green bin program). Surveys were used to collect data to understand: i) the predictors of household green bin support …

The video game industry has been examined since the 1970’s, yet individual country analysis from an economic geography perspective has been lacking. It is the contribution of this dissertation to utilize the agglomeration economy and location theory literature in its application to the Canadian video game industry.

To understand this industry, a mixed-method approach is used. Kernel density maps, standard deviational ellipses, and mapping processes were used to illustrate the dispersion and clustering patterns of studios in Canada. In addition, a Poisson regression was performed using count data of the number of video game firms in census metropolitan areas. The …

Equity Considerations In Active School Travel Interventions, Alina Medeiros

Electronic Thesis and Dissertation Repository

Active school travel has benefits for children’s physical and mental health, academic achievement, and the environment. Underscoring active school travel is children’s independent mobility, defined as their ability to travel around their community without adult supervision. Interventions have shown some success in reversing declining trends in active school travel and independent mobility. However, little is known about how interventions have varying impacts on different subgroups of children. This thesis identifies ways to increase equity in active school travel interventions by investigating how equity is currently considered in interventions and gendered disparities in children’s ability to engage in independent mobility. This …

Application Of Artificial Intelligence And Geographic Information System For Developing Automated Walkability Score, Md Mehedi Hasan

Dissertations

Walking is considered as one of the major modes of active transportation, which contributes to the livability of cities. It is highly important to ensure walk friendly sidewalks to promote human physical activities along roads. Over the last two decades, different walk scores were estimated in respect to walkability measures by applying different methods and approaches. However, in the era of big data and machine learning revolution, there is still a gap to measure the composite walkability score in an automated way by applying and quantifying the activityfriendliness of walkable streets. In this study, a street-level automated walkability score was …

Faits Accomplis In The Shadow Of Shifting Power, Joshua Adam Hastey

Graduate Program in International Studies Theses & Dissertations

The military fait accompli is so understudied a phenomenon in the international relations literature that even its definition is not widely known. A fait accompli is a unilateral revision to the status quo in an ongoing dispute over some distribution of benefits. Though recent work has demonstrated that faits accomplis are relatively common events in international history and current international relations, the subject remains undertheorized and empirically underexplored. This dissertation seeks to open up the conversation about faits accomplis in two complementary ways. First, it advances an original formal model of faits accomplis in the shadow of power shifts, …

Variability In Historical Fire Patterns Of A Moist Mixed-Conifer Forest In The Northern Blue Mountains Of Oregon, Laura Marie Platt

Dissertations and Theses

High variability in historical fire patterns characteristic to mixed-severity fire regimes is expected to have contributed to a structurally heterogeneous landscape throughout much of the forested ecosystems of the western United States. After more than a hundred years of fire exclusion in the region, many forests have shifted to a more homogeneous structure, which raises concern regarding these forests' ability to sustain expected increases in fire activity with a warming climate. The shift is not uniform across the west, however, and differences in historical disturbance patterns and changes due to land management are not well characterized in forests across a …

Understanding Agrihoods: An Exploration Into The Growing Trend Of Farm-To-Table Communities Across The United States, Benjamin Breger

Masters Theses

Agrihoods are a recent trend in real estate development that integrate agricultural amenities - such as working farms, orchards, or community gardens - into residential or mixed-use communities. As an emergent trend, agrihoods have the potential to enhance farmland preservation and local and regional food systems, making them a ripe area for research. However, very little scholarly research has been carried out to characterize, contextualize or evaluate agrihood developments. Thus far, the development model has primarily been detailed in popular media sources. This thesis serves as a baseline study that seeks to understand how neighborhood food systems operate within agrihood …
