Characterization Of The Intrinsic Neural Timescale Indices As A Reliable Fingerprint Of Brain Dynamics, Helya Honarpisheh

Dissertations and Theses

Intrinsic neural timescales (INTs) characterize the persistence of neural activity over time and offer insight into the brain’s temporal hierarchy. This thesis evaluates and compares six autocorrelation-based INT metrics—AR(1) Coefficient (Autoregressive Coefficient at 1), First Zero Lag, Lag at ACF = 1/e, Sum of Positive ACFs, ACF at Half Lag, Exponential Decay Constant (τ)— using resting-state fMRI data from 400 cortical regions across a large, lifespan sample (ages 6– 85) from the NKI-Rockland dataset. A discriminability analysis revealed that the AR(1) coefficient provided the highest test-retest reliability and individual specificity across repeated scans, establishing it as the most reliable INT …

Metasurfaces And Their Applications In Photonic Devices, Shuwei Guo

Dissertations and Theses

Metasurfaces are flat artificial optical elements composed of dielectric and/or metallic nanostructures. They can manipulate light in unprecedented ways by altering amplitude, phase, and polarization at subwavelength scales. The ability of these two-dimensional elements to perform multiple optical functions within compact optical systems—while offering high functionality, small form factors, and easy integration into optoelectronic devices—has sparked significant interest across various fields and industries. These applications span imaging, sensing, nonlinear and quantum optics, optical computing, automotive technology, augmented and virtual reality, and more.

In this dissertation, we explore and design new multifunctional metasurfaces with a focus on manipulating spectral responses. First, …

Generation And Characterization Of Human Blood-Brain Barrier Models For Investigating Neuropsychiatric Disorders And Tumor Metastasis, Yunfei Li

Dissertations and Theses

The blood–brain barrier (BBB) is important in the normal function of the central nervous system (CNS). An altered BBB has been described in various neuropsychiatric disorders. The brain-specific microvascular endothelial cell (BMEC) is an essential structural component of the BBB. To test if integrity of the BBB formed by BMECs is compromised in 22q11.2 deletion syndrome (also called DiGeorge syndrome), which is one of the validated genetic risk factors for schizophrenia, a 2D iBBB (induced BBB) on a Transwell filter was generated from human microvascular endothelial cells (HBMECs) derived from the induced pluripotent stem cells (iPSCs) out of patients with …

The Role Of Social Inequality In The “Feminization” Of Borderline Personality Disorder, Jane Goldie Ekhtman

Dissertations and Theses

Borderline personality disorder (BPD) is a severe and prevalent mental illness that is three times more likely to be diagnosed in women than men. BPD research has attempted to explain this gender disparity, with clinician gender bias emerging as a possible factor. Yet, no research to date has examined the role of social status in the overdiagnosis of women with BPD. There is merit in examining BPD through a class lens as low SES is a risk factor for BPD, poverty and income inequality disproportionately affect women, and low status is associated with stereotypical traits of femininity. Additionally, mental health …

A Wall Of Smoke: Understanding The Drivers Of The June 2023 Canadian Wildfire Smoke Event For New York City, Gregory S. Randazzo

Dissertations and Theses

The 2023 Canadian wildfire season was notable for its extent and the dense smoke it produced. Motivated by the resulting air quality impacts in the New York City region, we explore how the total particulate matter output from the Quebec fires influenced PM2.5 concentrations downstream in New York City. Using injection height data from the Regional Advanced Baseline Imager + VIIRS Emissions dataset, we relate the tropospheric injection heights of the fires with the broader synoptic context and surface PM2.5 concentrations. Using data from the NYS Mesonet Profiler Network, radiosondes, and ERA5 reanalysis, we document the connection between an anomalous …

Peacekeeping In Sierra Leone And Mali, Ishaka Kondeh

Dissertations and Theses

By analyzing the United Nations Mission in Sierra Leone (UNAMSIL) and the United Nations Multidimensional Integrated Stabilization Mission in Mali (MINUSMA), this research explores the impact of these missions on Mali still in conflict and long-term peacebuilding. The study focuses on three critical areas: supporting democratic governance, ensuring human rights protections, and successfully reintegrating former combatants into society. Through a comparative approach, this research analyzes why some peacekeeping missions succeed and then …

The Rise Of China: Economic Expansion, Military Modification And The Belt And Road Initiative, Felix Padilla

Dissertations and Theses

In order to analyze China’s rise in power, we have to examine how China has achieved this growth. We need to observe their domestic reforms, international initiatives like the Belt and Road Initiative (BRI), and strategic military advancements. This thesis focuses on China’s economic integration, market reforms and military modernization. The thesis uncovers the effects of this rise on global governance and power balances, especially in trade, security, and geopolitics. I analyze China's vision of a multipolar world and how it contrasts with the current global order and how this fuels rivalry with the U.S. and other powers. China's rise …

Testing An Educational Intervention To Improve Recognition And Understanding Of Emotional Manipulation In Romantic Relationships, Tiss Zaitz

Dissertations and Theses

Romantic relationships significantly impact happiness and well-being, yet rarely is it taught how to build them or recognize unhealthy relationship dynamics. This gap has profound implications, as Emotional Manipulation (EM) can have severe and lasting consequences. This study examined whether an educational intervention could improve participants' ability to recognize and understand EM in interpersonal relationships. Participants (N = 327) completed a pretest assessing recognition and comprehension of EM and were then given an answer sheet with detailed explanations to enhance understanding. A subset (n = 46) completed a posttest to measure changes in recognition and knowledge. Results showed significant improvement …

Unveiling Invisible Wounds: Experiences Of Racial Microaggressions, Racial Gaslighting, And Mental Health Among Racially And Ethnically Minoritized Adults, Supriya Pandit

Dissertations and Theses

Racial microaggressions are momentary, subtle, and often unintentional comments or behaviors that nonetheless communicate negative race-based messages towards racially and ethnically minoritized individuals. Given the accumulated and differential impact of racial microaggressions on individuals' mental health over time, it is crucial to investigate its associations with specific mental health symptoms and intrapsychic alleviating factors. To further clarify which coping strategies for racial microaggressions can be more empowering versus harmful, it is also crucial to investigate the processes and mental health consequences that unfold when individuals choose to challenge racial microaggressions, such as racial gaslighting. Racial gaslighting is an insidious interpersonal …

The Transformative Power Of An Ethic Of Care In Patricia Piccinini’S Mythic Posthuman Offspring, Keely Parrish

Dissertations and Theses

This thesis examines the contemporary artist Patricia Piccinini and her posthuman hybrid creations within the context of a feminist ethic of care. Largely referring to scholarship by the political scientist Joan C. Tronto, I argue that Piccinini expands the definition of an ethic of care to include non-human entities as well as human ones. The four phases of care identified by Tronto will serve to outline the encounter between the audience and Piccinini’s work to see how humans and non-humans (1) care about, (2) take care of, (3) give care and (4) receive care from each other, as well as …

Revelations: Spirituality As Privileged Perspectivism In Magical Realist Distortions, Isabella Scala-Kazanecki

Dissertations and Theses

This thesis examines the role of spiritual beliefs in the literary mode now known as magical realism in Cuban Alejo Carpentier’s The Kingdom of This World (1949), Indian-Born British and American Salman Rushdie’s The Satanic Verses (1988), and a lesser-known novel, Household Saints (1981) by Francine Prose, an American writer. The Kingdom of This World, itself the originator of the mode of magical realism, has allowed me to conclude with Carpentier that magical realism arises from “privileged revelations,” as he notes in the preface to his seminal book. But these revelations in magical realism are not necessarily always of the …

Living By The Sword: Religiosity And The Terrorist Subculture Of Russian Revolutionaries, 1904-1910, Gregory I. Mcevoy

Dissertations and Theses

The Marxist dictum of “religion is the opiate of the masses” has led to a prevailing assumption in scholarship that the socialist movements of the early twentieth century have been inherently atheistic. Religion is often associated as a remnant of old, antiquated society and incompatible with the claimed modernity of socialist progress. This assumption has led to overlooking the religiosity within certain radical movements and revolutionary culture at large. Scholarship on the political underground in Tsarist Russia has, thus far, perpetuated this impression. While it is the true that the Bolsheviks and Leninist Social Democrats rejected religion as obscurantist and …

Posters, Propaganda, & Bloody Saturdays: Making China Christian: How Media & Missionaries Made China Christian, Kristy Lee

Defining ‘Un-Americanism’ In Culture And Art: The Dies Committee’S Investigation Of The Federal Theatre Project, Matthew G. Summers

Dissertations and Theses

This thesis explores the House Un-American Activities Committee’s (HUAC) expansive definition of ‘Un-Americanism’ through the body’s 1938 investigation of the Federal Theatre Project (FTP). The committee, then known as the Dies Committee after its chairman Martin Dies (D-TX), publicly presented the hearings as an attempt to root out communism in a deeply compromised government program. And indeed the FTP, an ambitious New Deal Program to provide work for unemployed professionals in the theatre, had an undoubtedly leftist bent. However, the hearings were consistently focused on the project's progressive stances on issues of race and gender, and effectively exposed the underlying …

Asian-American Literature And The Family Saga: Cyclical Histories Of Racial Melancholia And Racial Dissociation, Molly Schwarz

Dissertations and Theses

This paper analyzes the novels The Namesake by Jhumpa Lahiri, Pachinko by Min Jin Lee, and Miss Burma by Charmaine Craig and argues how the family saga within Asian American literature draws out elements of the diaspora to best share histories across different ethnic and racial groups. There is a brief overview of the development of Asian-American literature and an explanation of how hyphenated identity is intrinsic to diasporic literatures, and then further discussion of how each of these novels contributes to the legacies of Asian-American writing and storytelling. Then, each novel is analyzed for how the various family saga …

The Sand Creek Massacre And The History Of Greater Reconstruction In The American West, Anna E. Plotnick

Dissertations and Theses

In the traditional U.S. historical narrative, the Civil War & Reconstruction era is a North vs. South story. Nevertheless, the era of western expansion, a central theme throughout the nineteenth century, has no contingent place within this traditional narrative. Meanwhile, the history of the American West and its diverse peoples appears in many textbooks as an unrelated albeit contemporaneous narrative. Separated by geographical regions, historians often do not examine these concurrent histories. However, many of these historical events and actors were interconnected. As I am interested in understanding the Reconstruction era’s national impact, I intend to explore how Reconstruction policies …

“The New Illiteracy”: “Why Johnny Can’T Write” At 50, Carl Schlachte

Publications and Research

This article is a retrospective history on Newsweek magazine's December 8, 1975 cover story "Why Johnny Can't Write" by Merrill Sheils. Based on interviews with Sheils and her researcher Frederick V. Boyd, I detail the context from which this article emerged, and the role that the two employment and gender discrimination lawsuits at Newsweek in the early 1970s played in shaping this article's publication. I also examine the legacy of "Why Johnny Can't Write" within the field of writing studies.

The Limits Of Technocratic Degrowth: A Review Of The End Of Capitalism: Why Growth And Climate Protection Are Incompatible—And How We Will Live In The Future, Michael Kirby

Publications and Research

This book review discusses Ulrike Herrmann’s The End of Capitalism: Why Growth and Climate Protection Are Incompatible—and How We Will Live in the Future, situating it within contemporary climate debates. Herrmann’s central claim—that capitalism’s dependence on perpetual growth renders meaningful climate protection impossible—is presented as a clear, accessible synthesis of degrowth arguments. The book is particularly notable for its rejection of techno-utopian solutions such as carbon capture and its skepticism vis-à-vis large-scale renewable transitions under market conditions. However, the review ultimately questions the feasibility of Herrmann's proposed alternative (the “survival economy”), demonstrating that it overlooks political power, class interests, and …

From The Heart: Writing Love Poetry With Ai, Dan Ryan

Open Educational Resources

The chief reason our writing students turn to AI is not "laziness.” It’s fear. This lesson plan helps college students overcome their fear of a first-time poetry assignment by empowering them to partner with “collaborators”—first AI, then each other—to co-write a love poem before finally writing a poem on their own. This 4-hour lesson plan for a college-level Introductory Creative Writing course includes three low stakes drafting and revision assignments, and culminates in a high stakes poetry assignment.

A Morphosyntactic Study Of Arab American Code-Switching, Qamar Bazar

Publications and Research

This study examines the morphosyntactic behavior of Arabic lexical items in English-dominant speech among Arab American bilinguals. Based on original survey data from 22 participants between the ages of 16 and 32, the paper focuses on specific Arabic words, such as yani, khalas, and ana, in English conversations across informal and professional settings. The analysis shows that these lexical items function as free morphemes and are inserted without disrupting English syntax, often serving discourse, emotional, or identity-marking purposes. Grounded in sociolinguistic theory and Poplack’s model of intra-sentential code-switching, this paper argues that code-switching among Arab Americans is intentional and …

Does Performance Change Budgets? Punctuated Equilibrium, Performance, And The Budget For Juvenile Justice In An American State, Elaine Yi Lu, Robert Hines, Katherine Willoughby

Publications and Research

How performance informs budgeting and budgets is contentious and unclear. Applying punctuated equilibrium theory, this research seeks to understand if performance information once placed on the media and macropolitical agendas can lead to long term budgetary shifts. This research highlights how the accumulation of performance information punctuated the funding scheme and created a new equilibrium over time.

This research uses mixed methods to study the impact of performance on Florida’s (USA) Department of Juvenile Justice (DJJ) over a 20-year period. First, we conduct a media review of 400 randomly sampled newspaper articles to characterize the media discourse around the DJJ …

Assessing The Predictive Validity Of The Network Inventory Of Risk, Victories, And Needs Assessment (Nirvana) For Youth Receiving Prevention Services., Michael T. Baglivio, Kevin T. Wolff, Katherine Jackowski

Publications and Research

The current study assesses the predictive validity of a newly-developed holistic risk/needs assessment for youth receiving prevention services. Employing a multiyear statewide sample of over 17,000 prevention youth, multivariate and Area Under Curve techniques are used to examine predictive validity in predicting future formal juvenile justice system involvement (new law violations) across sex, race/ethnicity, and multiple youth age ranges. Furthermore, predictive validity across the severity of the subsequent offense type (misdemeanor, non-violent felony, violent felony) was examined. Findings demonstrate large effect sizes for static risk only, dynamic risk only, and total risk plus protective scores on future offending. Sex and …

The Towering Inferno: Art, Policy, And Legacy, Charles R. Jennings

Publications and Research

The Christian Regenhard Center for Emergency Response Studies, leveraging the expertise of its faculty, staff, Advisory Board and colleagues, has consistently programmed activities focused on high-rise fire safety. The upcoming 50^th anniversary of the film The Towering Inferno was an inspiration.

We decided this would be more lighthearted and less purely technical than many of our events. We wanted to consider both the film, and use it to reflect on the state of fire safety in tall buildings in New York City.

Of course it does not escape us that the topic of fire safety is a serious one, …

Victim-Offender Overlap Among Incarcerated Youth In The United States: A Bivariate Probit Analysis Using National Data, Tzu-Ying Lo, Yu-Hsuan Liu, Amy Adamczyk

Publications and Research

For many crimes, people who are the perpetrators may also be the victims. While several studies have investigated the victim-offender overlap, very few have examined the relationship for incarcerated youth where institutional conditions can exacerbate the overlap. Drawing on ideas from routine activities theory, this study explores the victim-offender overlap among incarcerated American youth using data from the 2008–2009 National Survey of Youth in Custody (NSYC-1, N = 8,625) and the 2012 National Survey of Youth in Custody (NSYC-2, N = 8,125). Findings from a bivariate probit regression indicate that younger age, higher facility populations, negative perceptions of officer legitimacy, …
