X-Ray Emission In Illustristng Circum-Cluster Environments: Ii. Possible Origins Of The Soft X-Ray Excess Emission, Celine Gouin, Daniela Galárraga-Espinosa, Massimiliano Bonamente, Stephen Walker, Mohammad Mirakhor, Richard Lieu, Clotilde Laigle, Etienne Bonnassieux, Charlotte Welker, Stefano Gallo, Tony Bonnaire, Jade Paste

Publications and Research

Context. An excess of soft X–ray emission (∼0.2 − 1 keV) above the contribution from the hot intracluster medium (ICM) has been detected in a number of galaxy clusters, including the Coma cluster. The physical origin of this emitting medium above the hot ICM has not yet been determined, in particular, it is unclear whether it is thermal or nonthermal.

Aims. We investigate the gas phase and gas structure that reproduce the soft excess radiation from the cluster core to the outskirts best using simulations.

Method. By using the IllustrisTNG simulation (TNG300), we predict the radial profile of thermodynamic properties …

Foreword: Resisting Erasure: Libraries In Palestine And Palestine In Libraries, Emily Drabinski

Publications and Research

This foreword opens an anthology that explores research and experiences at the intersection of Palestine and libraries. Part one examines how Palestinian librarians, archivists, and individuals resist erasure by preserving Palestinian materials and narratives and by ensuring Palestinians’ access to library resources amidst recurring cycles of destruction and confiscation. Part two explores how librarians in the United States respond to pressure from right-wing and pro-Israel advocacy groups that are quick to label any effort to include Palestinians and their histories as antisemitic.

Distribution Of Power In South Asia: Assessing Sino-Indian Conflict Propensity, Fatima Faisal

Dissertations, Theses, and Capstone Projects

In international relations, the distribution of power is a key theme impacting the propensity for nations to break into wars; however, the vast academic literature is Eurocentric with a concentration on the United States and the Soviet Union. This paper shifts to the unexplored distribution of power in South Asian with a particular focus of Sino-Indian border conflicts namely the Sino-Indian War (1962), the Nathu La and Cho La clashes (1967), the Arunachal Ambush (1975), Sumdorong Chu standoff (1987), the Armed Confrontation (2013), and the Doklam Standoff (2017), and the Galwan Valley (2020) to determine if the region was more …

Finding Luis: A Creative Nonfiction Account Of Law & Society, Jason M. Leggett

Dissertations, Theses, and Capstone Projects

This essay explores the contradictions in legal theory and human experience through creative nonfiction. Its main purpose is to argue that a truly just society requires acknowledging the profound influence of individual narratives on the law. This is supported by blending personal narratives, critical analysis, and philosophical inquiry to reveal the gap between codified law and lived realities for marginalized individuals. This unique Legal Poetics methodology employs a series of six vignettes, such as the author's and Luis's shared experiences with traumatic brain injury and the denial of justice, as data. By integrating autoethnography, law as narrative, and performativity theories, …

Mechanistic Studies Of Aerobic Photochemistry: Gold Nanoclusters, Nanoparticles, And Solution-Phase Systems, Serah Essang

Dissertations, Theses, and Capstone Projects

Chapter 1 describes our findings on the reactions of Au glutathione nanocluster (Au₂₀SG₁₆) with singlet oxygen (¹O₂) in D₂O. We noticed it underwent a self-photooxidation reaction. Leading us to mechanistic studies using photophysical, photochemical, theoretical, and indirect trapping methods. We found rapid total quenching of singlet oxygen (¹O₂) by ground-state Au₂₀(SG)₁₆, with evidence for dioxygen insertion into the nanocluster. Supported by analyses with IR, ESI-MS, and density functional theory, we propose the formation of …

Recognition At Work: How Managerial Acknowledgment Shapes Team-Level Outcomes, Annalissa Thomas

Dissertations, Theses, and Capstone Projects

Employee recognition has become a central focus for organizations worldwide, with billions of dollars spent annually on recognition programs. Despite this investment, scientific research on the effectiveness of recognition beyond performance outcomes remains limited. Furthermore, little is known about how recognition operates at the team-level and the specific attributes that make recognition impactful. This study addresses these gaps by disentangling the nuanced attributes of recognition and exploring their influence on employee perceptions of recognition. It also examines how these perceptions affect key outcomes, including perceptions of manager support, job security, autonomy, team cohesion, and engagement, and tests whether trust moderates …

Computational And Functional Characterization Of Terebrid Venom Peptides, Favour T. Achimba

Dissertations, Theses, and Capstone Projects

Venom peptides represent a natural repertoire of bioactive compounds that are potent modulators of ion channels. Teretoxins, venom peptides from terebrid snails, remain underexplored despite their structural and functional diversity. This thesis is the first to comprehensively explore the structure and function of teretoxins using a comparative computational sequence and structure model followed by experimental assays. The majority of the functional focus has been on identifying the ion channel molecular targets of uncharacterized teretoxins. Teretoxins, like other venom peptides, are hypothesized to manipulate the cellular function of a diversity of ion channels. Dysregulation of ion channels leads to several …

Sometimes I Picture You Dreaming: How American Female Directors Use Women-In-Prison Films As A Pathway For Public Education And Activism In The Era Of Mass Incarceration, Nicolette Natale

Dissertations, Theses, and Capstone Projects

This thesis examines the role of female directors in creating media that showcases how prisons perpetuate sexism or gender-based violence. As mass incarceration began to take off in the 1970s, this paper begins with an analysis of Jack Hill’s The Big Doll House (1971), which often served as the model for women-in-prison (WIP) exploitation films. While Hill perpetuated the white and male gaze in The Big Doll House, Stephanie Rothman subverts oppressive gazes in her WIP film, Terminal Island (1973), and demonstrates a concern with the historical gendered realities of prison – moving beyond representations of prison on the …

Social Capital And The Spread Of Information On Twitter Related To Change In The Criminal Legal System, Sebastian Hoyos-Torres

Dissertations, Theses, and Capstone Projects

Criminal legal reformers and abolitionists have differing visions for change within the criminal legal system, where reformers seek to modify and abolitionists aim to dismantle it altogether (Davis 2005; Foucault 1977; Kaba 2020). Advocates used print media to disseminate information related to their proposed changes to broader audiences. While print media remains a valuable tool to reach wide audiences, the advent of social media introduced new mechanisms to interact with broad audiences at very low cost while leaving traces of digital data which could be analyzed to better understand the social factors which impact whether information is spread. Throughout this …

Development Of Novel Anti-Cancer Colchicine Analogs: Synthesis And Configurational Studies, Orugbani S. Eli

Dissertations, Theses, and Capstone Projects

Colchicine, a naturally occurring alkaloid, has long been known as a potent therapeutic agent. Despite its efficacy treating gout and other inflammatory disorders, its severe toxicity, limited selectivity, and poor pharmacological profile have restricted its broader clinical application. Reported advantages of colchicine-site ligands as vascular-disrupting agents, including reduced susceptibility to multidrug resistance, have revived interest in the colchicine site on tubulin as a validated therapeutic target for cancer. This dissertation focuses on the development of new colchicine analogs, detailing the synthetic method to functionalized AC-ring derivatives, as well as the evaluation of their configurational stability and biological activity.

Replanting Hawthorns: Towards A Diachronic Translation Of À La Recherche Du Temps Perdu, Gerardo Bandera

Dissertations, Theses, and Capstone Projects

A novel as long and complex as Marcel Proust's À la recherche du temps perdu poses a challenge of methodology to its translators: how should one proceed with rendering its unique style, its bifurcating sentences, its aesthetic philosophy, and the interplay between content and form? What should one prioritize? This dissertation proposes a method of translation that gives priority not only to sentence structure, as most English translators of the novel have done, but also to the repetition and diachronic development of images, themes, and phrases in order to capture and recreate certain recursive effects of the novel’s form. It …

Filling The Gaps: Maiti Nepal And Anti-Trafficking Governance In Nepal, Sushmita Lamsal

Dissertations, Theses, and Capstone Projects

Human trafficking in Nepal is closely linked to labor migration, gender inequality, and weak state capacity. In this context, non-governmental organizations play a key role in anti-trafficking efforts. This capstone project examines Maiti Nepal’s approach to prevention, rescue, and rehabilitation, with focus on its work at border points and internal facilities provided to human trafficking victims. The study analyzes how Maiti Nepal functions as a quasi-state actor by addressing gaps in Nepal’s anti-trafficking framework, highlights challenges associated with limited inconsistent funding, uneven resource distribution, and support for survivors. The study argues that Maiti Nepal’s significance lies not only in its …

Foreign Songs, Occitan Voices, And The Guitar In Early Modern France (C. 1570-1650), Ana Beatriz Mujica Lafuente

Dissertations, Theses, and Capstone Projects

The cultural traditions of European nations are too often treated as independent and essential entities, obscuring the transnational and interregional exchanges that have shaped modern cultures. In musicology, recent studies have emphasized the plurality and mobility of people, cultures, and music in Europe. Yet, French songs are still largely explained within the framework of the national, generally privileging written over oral traditions, printed over manuscript music, national over regional languages, and monolingual over plurilingual practices. Through the study of songs in Italian, Spanish, Occitan, and Turkish, this dissertation challenges such preconceptions.

This study shows that secular songs in foreign and …

Molding The Mosaic: Progressive Coalition Formation In The 2021 New York City Council Elections, Sam Goodson

Dissertations, Theses, and Capstone Projects

The 2021 New York City Council primaries marked a decisive breakthrough for the city’s progressive left. A cohort of democratic-socialist and socialist-adjacent candidates won office across multiple boroughs, dramatically expanding the size and influence of the left flank of the council. This dissertation analyzes those victories and argues that they constituted a hinge moment in the construction of a progressive governing regime in New York City, with implications that extend beyond New York City politics to the study of social- democratic party families more broadly. Drawing on electoral returns, demographic data, campaign materials, and elite interviews, the project demonstrates that …

Build, Freeze, Expedite, Renew: Messages On Housing In The 2025 New York City Mayoral Campaign, Elizabeth A. Foley

Dissertations, Theses, and Capstone Projects

Polls of likely voters prior to New York City’s 2025 mayoral race suggested that proposing a persuasive solution to the city’s housing crisis was likely to be critical to the building of a winning electoral coalition. And an important factor in voters’ reception of each candidate’s housing proposals would be the role that housing developers are perceived to play in those solutions. Developers, who are widely regarded as unscrupulous profiteers in a local housing landscape where the deck is always already stacked against the renter or home buyer, figure (accurately or not) as the chief villain in the story many …

Towards Unbordered Worlds: Mutual Aid Amid Border Internalisation In New York City, Holly Maclean

Dissertations, Theses, and Capstone Projects

This study explores the relationship between mutual aid and border regimes through the case of Tompkins Distro, a mutual aid group that organises a weekly food distribution in the East Village of New York City. It focuses specifically on two forms of border internalisation that have shaped the emergence and context of Tompkins Distro: welfare state bordering and interior border enforcement. Drawing on four months of participant observations, interviews with core organisers, and documentary analysis, the study examines how Tompkins Distro meets people’s needs each week through a framework of collective care that actively rejects border logics of deservingness and …

The dataset, compiled from historical migration statistics published by the Polish Central Statistical Office (GUS), is transformed into a browsable …

Maintenance Mode For Digital Dwellers, Maci Morris

Dissertations, Theses, and Capstone Projects

In an ever-expanding digital landscape that operates on the commodification of user-generated materials, whether through direct or “dark pattern” extraction, it becomes vital for educators to employ digital practices that normalize critical reflection about the creation and storage of digital content. These practices should create better understanding of the underlying infrastructure of content management and storage.

This capstone project, “Maintenance Mode for Digital Dwellers,” is an adaptable pedagogical guide that instructors can use to engage learners in strategies and systems for managing their personal digital materials. Participants are encouraged to engage with their digital maintenance and archival practices through a …

Reimagining Safety And Justice: Experiences Of And Resistance To Police Sexual Violence In New York City, Priscilla Bustamante

Dissertations, Theses, and Capstone Projects

In the era following both Black Lives Matter and #MeToo, police sexual violence (PSV) currently constitutes the second most commonly reported police complaint after excessive force. Police across the U.S. are caught for some form of sexual misconduct once every five days, with on-duty officers found to commit sexual assaults at more than double the rate of the general population. The gendered and racialized perpetration of sexual violence extends far beyond policing; however, it has been intensified within the masculine, militarized carceral structures designed to legally control and punish.

Accordingly, this dissertation utilizes an interdisciplinary, multi-method approach to offer what …

Open To The Public(S): Privatized Public Space, Technology, And Aspirational Wealth At Hudson Yards, Troy Simpson

Dissertations, Theses, and Capstone Projects

Using the publicly accessible plaza at the Hudson Yards development in New York City as a backdrop, this dissertation provides an examination of mechanisms by which public spaces—already under pressure from a range of factors including privatization and securitization—are further transformed via processes associated with the notion of smart cities initiatives, or platform urbanism. Following a literature review and presentation of relevant contextual background related to the history and configuration of the site, the data chapters present a range of operational and material mechanisms that cumulatively establish a class-based strategic provision of narrow boundaries for visitor access and activities oriented …

Online Visual Query System For Real-Time Large-Scale Spatio-Temporal Data Explorations With Error Bounds, Xueqi Huang

Dissertations, Theses, and Capstone Projects

Modern datasets continue to grow in size, dimensionality, and heterogeneity, creating increasing tension between the need for responsive, interactive analysis and the computational cost of accessing, aggregating, and visualizing large volumes of data. Traditional database engines and visualization tools often assume that full data retrieval is feasible or that exact computation is necessary for meaningful insight. In practice, however, analysts frequently benefit from timely, uncertainty-aware approximations than from delayed and exact results. This thesis investigates how data summarization techniques, specifically mergeable sketches can be combined with progressive, out-of-core visualization methods to support interactive exploration of datasets that exceed main memory. …
