From Ecclesiastical Tradition To Judicial Authority: Divorce In Scioto County, Ohio, 1809-1851, Franchesica Lashelle Kidd
From Ecclesiastical Tradition To Judicial Authority: Divorce In Scioto County, Ohio, 1809-1851, Franchesica Lashelle Kidd
Graduate Masters Theses
This thesis examines divorce in Scioto County, Ohio between 1809 and 1851 as a case study of the legal and social transformations that followed the American Revolution. While previous scholarship has focused primarily on New England and the colonial period, Ohio has received comparatively little scholarly attention. Using legislative records, court proceedings, census records, and individual divorce petitions, this study argues that Ohio’s transition from ecclesiastical precedent toward judicial authority reshaped the ways in which marriage and divorce were understood. Divorce became increasingly accessible to both women and men, while changing legal practices reflected broader shifts in gender, family, and …
Beyond A Little Italy: Italian Community Formation In Washington, D.C., Kathleen P C Millander
Beyond A Little Italy: Italian Community Formation In Washington, D.C., Kathleen P C Millander
Graduate Masters Theses
This thesis examines the development of the Italian immigrant community in Washington, DC, from the early nineteenth century through the beginning of the Second World War. Unlike the dense ethnic enclaves that characterized Italian settlement in many American industrial and port cities, Washington never developed a recognizable Little Italy. Nevertheless, Italians in the nation's capital constructed a cohesive community through social, religious, familial, and economic networks that connected a geographically dispersed population.
Drawing on extensive original archival research, including oral histories, personal memoirs, parish records, newspapers, and manuscript collections, this thesis reconstructs the experiences of Washington's Italian immigrants and their …
Propagating Labor: How The Craft Brewery Movement Attracted And Grew A Workforce To Fuel Its Rise, Timothy J. Vlieger
Propagating Labor: How The Craft Brewery Movement Attracted And Grew A Workforce To Fuel Its Rise, Timothy J. Vlieger
Graduate Masters Theses
The craft beer movement grew from just a few tiny microbreweries and disparate homebrewing clubs to a nationwide phenomenon accounting for over ten thousand businesses and hundreds of thousands of employees. The arrival of this movement in the 1980s coincided with drastic changes in the economy, which was moving away from the manufacturing base that enabled postwar prosperity and developing a “New Economy” of high-tech and service sector employment. Within this economic transition, the social contract between capital and labor was being rewritten and what constituted a good job was being redefined. Employment in the emerging craft brewing industry represented …
Synthesizing Viscoelasticity: Living Polymers, Micro-Macro Relations, And Paths For Resolution, Adam M. Hasler
Synthesizing Viscoelasticity: Living Polymers, Micro-Macro Relations, And Paths For Resolution, Adam M. Hasler
Graduate Masters Theses
This thesis investigates the relationship between macroscopic rheological signals and underlying microscopic dynamics in complex fluids, specifically focusing on ”living polymers” within the cetyltrimethylammonium bromide (CTAB) and sodium salicylate (NaSal) surfactant system. The research addresses the inverse parameterization problem, demonstrating how bulk measurements like zero-shear viscosity can mask fundamentally different physical topologies, such as purely cylindrical, reptating micelles versus highly branched networks. Through the successful synthesis of viscoelastically ”degenerate” samples, the study utilizes an array of characterization techniques including frequency sweeps, Large Amplitude Oscillatory Shear (LAOS) to resolve these unique underlying states. Furthermore, the work explores further avenues of study …

Shaping Disease: Colonial Stigma And The Politics Of Health In Banyuwangi, The Early Twentieth Century, Rifa'i Shodiq Fathoni, Skriptyan Noor Hidayatullah Syuhri, Vini’Matu Hikmah, Ardhita Zahra Namira
Paradigma: Jurnal Kajian Budaya
This article examines the colonial stigma attached to Banyuwangi as an “unhealthy region” in the early 20th century, a label used to justify massive exploitation of its natural resources. Using a historical method, this research analyzes how this stigma not only served as a tool for colonial legitimation but also causatively created conditions that triggered ecological disasters and a public health crisis in a previously isolated area. Through an analysis of primary sources such as colonial reports, health journals, and newspapers, this article traces how large-scale plantation exploitation, enabled by the stigma, led to deforestation, uncontrolled labor migration, and poor …

The method applied is textual criticism and comparative textual analysis in order to identify …
Universalism And Exclusion: Immigrants Through The Lens Of French Law And Media, George Mikhael Taliak, Abellia Anggi Wardani
Universalism And Exclusion: Immigrants Through The Lens Of French Law And Media, George Mikhael Taliak, Abellia Anggi Wardani
Paradigma: Jurnal Kajian Budaya
This research examines France’s Immigration Law LOI n°2024-42 du 26 janvier 2024 and its representation in three mainstream media outlets across the ideological spectrum: Le Figaro (right), CCFD-Terre Solidaire (left), and France Info (center). Using Critical Discourse Analysis (Fairclough, 1995) and Maurice Halbwachs’s theory of collective memory, the study explores how legal and media discourses construct symbolic and administrative boundaries of national citizenship. Findings reveal that integration is framed not as civic inclusion, but as the internalization of a singular national identity and memory. Media reinforce this framework through divergent but convergent discursive strategies. At the macro level, the law …
Redesigning Quantum Theory, Matthew Weiss
Redesigning Quantum Theory, Matthew Weiss
Graduate Doctoral Dissertations
QBism understands quantum mechanics to be probability theory supplemented by additional nonclassical coherence conditions. In this dissertation, we develop these nonclassical coherence conditions from first principles, emphasizing the role of a well chosen reference measurement. After treating standard probability on subjective Bayesian lines, we demonstrate an equivalence between the QBist approach and the existing framework of generalized probabilistic theories. We show that the fundamental nonclassical coherence relation may almost always be taken to be a gentle modification of the law of total probability, and give a coherentist account of when an experimental scenario has a classical explanation. Finally, we show …
Process And Change In The Global Governance Of Sustainable Development, Sarah B. Fascitelli
Process And Change In The Global Governance Of Sustainable Development, Sarah B. Fascitelli
Graduate Doctoral Dissertations
In 2015, to euphoric acclaim, the world adopted the 2030 Agenda for Sustainable Development. But with less than five years to deliver its seventeen Sustainable Development Goals (SDGs), the Agenda’s “transformational vision” remains unrealized. To understand why, this dissertation looks not to the Agenda’s implementation but to its birth, asking how the three-year process that produced it was designed, implemented, and experienced, and whether its mechanisms reinforced or challenged the structures that shape global sustainability governance. The premise is simple: how global agreements are negotiated matters as much as their substance. The study thus pushes back against a celebratory view …
A Discursive Analysis Of Lesbian And Queer Experiences Of Unwanted Consensual Sex, Sarah E. Swanson
A Discursive Analysis Of Lesbian And Queer Experiences Of Unwanted Consensual Sex, Sarah E. Swanson
Graduate Doctoral Dissertations
This study drew on a critical discursive psychology (CDP) analytical approach to examine how lesbian and queer participants made sense of unwanted consensual sex (UCS). The data analysis traced how UCS was constructed on three discursive levels: the construction of UCS across narratives, the interpretive repertoires mobilized (including sexual scripts), and the broader sociocultural discourses that shaped what elements of their experiences were intelligible. Therefore, I sought to understand both how participants drew on familiar heteronormative and queer ways of talking about sex and how various discursive resources shaped how they could construct themselves and others. Data for this research …

The Anti-Racist Organization? Power, Embodiment, And The Politics Of Becoming, Patricia Tiimah Naya
Graduate Doctoral Dissertations
Why do organizational justice commitments so rarely produce structural transformation, and what happens to the people who take them seriously? This dissertation addresses that question through a longitudinal qualitative study of Aequitas University, a large public urban research institution in the northeastern United States, during a multi-year attempt to become “anti-racist.” Drawing on 129 semi-structured interviews with 115 organizational members, 7 focus group discussions, four years of field observation, and an archival corpus spanning more than a decade of institutional history, the dissertation examines how justice commitments move through organizations over time. Justice commitments do not simply succeed or fail. …

From Structure To Experiences: How Facility Capacity And Staffing Shape The Adoption And Impact Of Lgbt-Affirming Policies In Long-Term Care, Andrew Alberth
Graduate Doctoral Dissertations
Long-term care (LTC) settings – including nursing homes (NHs) and assisted living facilities (ALFs) – provide necessary care for individuals with extreme health and functioning limitations. Sexual and gender minority (LGBT) older adults report challenges receiving effective, person-centered care LTC. Some LGBT older adults may hide their sexual orientation and gender identity when entering LTC settings or delay seeking needed LTC fearing discrimination from staff and other residents. Furthermore, staff in LTC settings indicate little awareness of LGBT-residents and possess inadequate LGBT-cultural competency necessary for providing person-centered care. Therefore, LGBT-residents LTC experiences remain underexplored in the broader research. Adopting LGBT-affirming …

Our Claims Matter: Latin American Migrants’ Nonviolent And Everyday Resistance Across Transnational Spaces, Pryanka Penafiel-Cevallos
Graduate Doctoral Dissertations
This dissertation examines how Latin American migrants engage in nonviolent resistance across transnational spaces in Ecuador, challenging dominant narratives that portray migrants primarily as passive actors or humanitarian subjects. Focusing mainly on Venezuelan, Colombian, and returned Ecuadorian migrants, the study places migrants’ political agency at the center of analysis. It asks how migrants resist, for what purposes, and under which conditions they mobilize nonviolent and everyday resistance practices to claim rights, dignity, and human security in a host country marked by both legal innovation and growing exclusion.
Drawing on civil resistance theory, everyday resistance approaches, and migration scholarship, the research …

The design of high efficiency inverse class-F (class-F-1) radio frequency (RF) power amplifiers includes extensive measurements to characterize the RF power device by means of the empirical load-pull test setup. This paper presents an alternative characterization approach based on evaluating the load impedances analytically at the desired harmonic frequencies for a high electron mobility transistor (HEMT) in terms of the internal and package elements of the active device. It additionally provides a method for extracting the parasitic elements of the power device as well as determining the optimum load-line resistance using the transistor manufacturer’s large signal model. A new topology …

The research deals with the concept of ethical responsibility as one of the most influential concepts in the process of practicing architecture. It is defined as “systems of ethical principles and engineering rules governing the architect in making decisions of design practice, making them sound, preventing them from making mistakes during the stages of design, and the maintenance “by the commitment to them, result in creative architectural texts benefit the individual and society,” and thus determine the research problem in (Lack of cognitive perception of the role of moral responsibility in the practice of architecture). Therefore, the research aims at …
