Negation In Dene Languages, Cormac League

Linguistics ETDs

This thesis uses a typologically informed approach to investigate the strategies used for negation in Dene languages. This study illuminates aspects of the development of negation by examining the complex interplay between the lexical forms and morphosyntactic strategies employed to encode negative polarity in declarative and prohibitive constructions. The theoretical frameworks of the Jespersen Cycle and the Negative Existential Cycle are utilized to discuss negators in relation to their possible origins. Particular attention is given to the Pacific Coast and Southern Dene languages to propose an origin for the bipartite negation strategies used in the later. Through examination of synchronic …

Grievability And The Contingency Of Life Value In Twenty-First-Century Science Fiction, Emily A. Reiff

English Language and Literature ETDs

Using Judith Butler’s framework of grievability, this dissertation explores twenty-first-century science fiction by British, Irish, and Caribbean authors whose novels grapple with legacies of colonialism and imperialism that relied on dehumanization and subjugation. Beginning with Sarah Maria Griffin’s Spare and Found Parts (2016), chapter one explores neocolonial rationales—purportedly based on health—which recreate colonial divisions of class and labor and enforce systems of diminishing grievability in a post-apocalyptic Irish context. Chapter two contends that Kazuo Ishiguro’s Klara and the Sun (2021) illustrates the danger inherent to value systems that center “normative” embodiment in worlds that reconfigure hypercapacitated human beings as the …

“How I Dress Is No One’S Business!”: Fashion As A Subversive Language Of Resistance Among Female Christian Celebrities In Ghana, Amanda E. Gyesi

Communication ETDs

Influenced by burgeoning literature on feminism and feminist theories, specifically within the African context, I analyze the intersection of religion and celebrity culture among a select group of women in Ghana. Using the African feminist critical discourse analysis, guided by Stuart Hall’s encoding and decoding model, this research examines how female Christian celebrities in Ghana enact resistance, project their agency, and shape their identities through their fashion statements and sartorial choices, hence contributing to the broader discourse on fashion communication among religious women.

Through a critical analysis of Instagram comments and YouTube interview transcripts, I argue that fashion communication among …

(Dis)Connecting Incommensurable Relationalities: Aesthetics Of Desirable Citizenship & Interethnic Solidarity In Vietnamese/American Diasporic Media, Anh A. T. Nguyen

Communication ETDs

Employing critical diasporic rhetoric to articulate the pull and push glimmer of essentialist and nationalistic agendas of constructing Vietnamese diasporic subjectivities, I elucidate the complicated structure of diasporic nationalism that gives shape to ambiguities, paradoxes, and contradictions of Vietnamese diasporic withdrawal and regroupment in interethnic politics. Through three case studies explicating Vietnamese diasporic responses to the Chinese virus rhetorics, the appearance of the South Vietnamese flag on January 6 Capitol grounds, and the Atlanta shootings in Saigon Broadcasting Television Networks (SBTN), I highlight how Vietnamese diasporic authorities perform and enact citizenships of becoming desirable, which elevates oppressive forces of ideological …

A Usage-Based Account Of Ongoing Structural Changes In Sanapaná: Grammar Sketch And Case Studies, Jens E. L. Van Gysel

Linguistics ETDs

This dissertation presents three case studies on sociolinguistic variation in Sanapaná, an Enlhet-Enenlhet language spoken by around 1000 people in Paraguay. It investigates the impact of the process of language shift towards Paraguayan Guarani and Spanish that Sanapaná is undergoing. Specifically, it attempts to disentangle the effects of speakers’ multilingualism in Spanish and/or Guarani, their frequency of use of Sanapaná, and structural factors internal to Sanapaná on phonetic, morphological, and syntactic variation. It finds that Spanish/Guarani proficiency is correlated with L1-to-L2 convergence in Sanapaná vowel productions and use of different motion framing strategies, while frequency of Sanapaná usage is a …

Parallel Multigrid In Time For Chaotic Dynamical Systems, David Alan Vargas

Mathematics & Statistics ETDs

Despite the fact that Parallel-in-Time (PinT) methods are predicted to become necessary to fully utilize next-generation exa- and zettascale machines, there are currently no known practical methods which scale well with the length of the time-domain for chaotic problems, due to exponential dependence of the condition number on the fastest chaotic timescale. I present modifications to the coarse-grid equations along with a novel rediscretization approach which together greatly improve convergence of the multigrid reduction in time (MGRIT) algorithm and allow the first known PinT speedup for a chaotic PDE. The novel Local Shadowing Relaxation (LSR) is presented as an alternative …

Media Road To Violence: A Process Of Racialization Of Rohingya Ethnic Minority, Md Didarul Islam

Communication ETDs

ABSTRACT

This dissertation examines how ideologically loaded news media representations advanced the complex and ambiguous process of racialization of the Rohingyas, an ethnic Muslim minority in Myanmar. This study first interrogates the dominant patterns in news sourcing and thematic emphasis in the coverage of Rohingya; secondly, it sheds light on how these representations contribute to reproducing dominant ideologies and power relations. I selected two English-language newspapers published in Myanmar: The Global New Light of Myanmar and the Myanmar Times. I applied the notions of media representation (Hall, 1997), ideology (Althusser, 2007), and racialization (Garner & Selod, 2015) as the central …

Optical Responses Of Hybrid Electromagnetic Nanostructures, Dominic Bosomtwi

Optical Science and Engineering ETDs

Fano resonances result from the interference between a broad background and a narrow state, producing asymmetric scattering profiles. Under specific conditions, destructive interference collapses the Fano resonance width, leading to bound states in the continuum (BICs) that localize light within a nanostructure while maintaining an infinitely high-quality factor (Q-factor).

This dissertation explores the design of nanostructures with multilayer hybrid plasmonic-dielectric metasurfaces using full-wave numerical simulations, facilitating multiple Fano resonances and BICs. By adjusting nanoantenna dimensions, multiple modes are excited at plasmonic-dielectric interfaces, leading to strong interactions and hybridization of energy levels, manifested as Rabi splitting.

These findings enable advancements in …
