Major, Trace And Rare Earth Element Concentrations In Nist Standard Reference Material® 1646a Analyzed By Als Global Using Method Me-Ms61r, Jane L. Alexander

Publications and Research

This technical note compares analytical results obtained from ALS Global Method ME-MS61r with the certified and previously published results for NIST Standard Reference Material® 1646a, Estuarine Sediment. The results are grouped into major, trace and rare earth elements, and focus on elements used by sedimentary geochemists, for example in studies of sediment provenance. The results from ALS Global Method ME-MS61r are internally consistent and generally robust when compared with published analyses. However, acid digestion may not completely dissolve resistant minerals, leading to under-reporting of some elements such as Ti, Cr, Zr, heavy REE and Y.

The Georgian Of Heritage Speaker Children, Cass Lowry

Dissertations, Theses, and Capstone Projects

This dissertation presents three research articles united in the goal of describing the Georgian language as it is spoken by heritage speakers in the Brooklyn diaspora. The Georgian heritage speaker subjects recruited for these studies were children due to immigration patterns at the time when experimental data was collected. Their production of morphosyntactic inflection and pronouns is compared to adult and child homeland speakers.

Heritage speakers of Georgian demonstrate the following divergences from homeland and standard language comparisons. Nominal case inflection is most affected in heritage production, as heritage speakers use a default case or collapse Georgian's split-ergative and inverse …

Interoceptive Forecasting And Recall: The Role Of Anxiety Sensitivity And Disgust Sensitivity, David Lloyd Yap

Dissertations, Theses, and Capstone Projects

Predicting and remembering emotional states (affective forecasting and recall) are adaptive processes that allow individuals to engage with the future and past to guide behavior, yet these processes are prone to bias. Although affective forecasting and recall biases are common across healthy populations, more pessimistically biased affective forecasts and recall have been linked to greater anxiety and depression symptom levels and to emotional disorders. A crucially understudied aspect of affective forecasting and recall is the perception of the somatic (interoceptive) symptoms that accompany emotions. This study investigated forecasting and recall accuracy of somatic symptom levels (i.e., interoceptive forecasting and recall). …

Receptions Of Mental Health Emergency Services In New York City, Daniel R. Samost

Dissertations, Theses, and Capstone Projects

Mental health emergency response has become a highly scrutinized topic following the Black Lives Matter movement and several notable incidents of mental health emergency service users being killed by police responders. Qualitative interviews were conducted with mental health emergency service users to better understand the experience of using mental health emergency services, garner critical feedback of the service, and explore recommendations to improve future response. A total of 23 participants conducted interviews and detailed 40 incidents of mental health emergency service utilization. These interviews were then coded and analyzed. There were a few major findings from the data. Just over …

Enjoyment In The Classroom: Reciprocal Student-Teacher Dynamics In Israeli Math Education, Yonaton Gutterman

Dissertations, Theses, and Capstone Projects

Enjoyment is increasingly recognised as a keystone emotion in contemporary models of academic motivation and learning (Pekrun, 2006; Ryan & Deci, 2020). Grounded in Control-Value, Expectancy-Value, and Self-Determination theories, the present study tracked reciprocal affective processes in Israeli mathematics classrooms across ten lessons. Seven teachers and their 257 students (112 fourth-graders; 145 eighth-graders) completed parallel post-lesson questionnaires assessing feedback use, enjoyment, and perceived difficulty. Multilevel ordinal mixed-effects models, latent-growth curve models, and Bayesian random-intercept cross-lagged panel models were estimated to disentangle within-person fluctuations from between-person differences (Hamaker et al., 2015). Confirmatory-factor analyses supported scalar invariance of the key scales over …

Love Amid The Rage: Feminist Affect In Women's Life-Writing, Genesis Siverio

Dissertations, Theses, and Capstone Projects

The aim of this thesis is to show the ways women’s emotions or affect, particularly rage and love, are described by women writers in their most intimate stories. I discuss the way emotion has been demeaned, and how feminist scholars have instead viewed the body as a place of insight, reclaiming a knowledge from the senses. In the midst of white supremacy and heteropatriarchy, women give voice to their affectual experiences and cultivate the feelings they have so often been denied. Focusing on the particular ways women’s anger manifests in their lives and in their bodies, I zoom in on …

Using Machine Learning Methods To Evaluate Undergraduates’ Executive Function In The Context Of Game-Based Measurement, Ming Chen

Dissertations, Theses, and Capstone Projects

Traditional performance-based measurements have faced criticism due to their potential to induce test fatigue and their limited ecological validity. In contrast, game-based assessments have demonstrated the capacity to engage participants effectively in tests and enhance ecological validity by replicating real-world scenarios. Nevertheless, conventional statistical approaches may prove insufficient in capturing the intricate, non-linear associations between participants' gaming performance and their cognitive capabilities. Leveraging the potential of machine learning (ML) techniques, which can model complex problems, offers a promising avenue for estimating students' performance in video games. This dissertation aims to explore various ML methods for the validation of three game-based …

Imagined Empires: Roman And Chinese Constructions Of One Another In Antiquity, Elizabeth S. Tsang

Dissertations, Theses, and Capstone Projects

This thesis examines how the Roman and Han Chinese empires conceptualized one another during the first centuries CE, despite never establishing sustained direct contact. It argues that mutual perceptions were shaped less by firsthand experience than by mediated reports, commodities, and the political interests of intermediaries. The study proceeds in four parts. The first explores how Roman authors employed the ethnonym Seres to frame China as a land of wonder, wealth, and alterity. The second analyzes the Chinese designation Da Qin, showing how it projected Han imperial ideals outward by casting Rome as a mirror-image polity. The third turns to …

Dónde Están: Searching For Desaparecidos Of The Argentine Dirty War, Paula Fleischer

Dissertations, Theses, and Capstone Projects

This project is a data physicalization textile representing the 30,000 'desaparecidos' from the Argentine Dirty War of late 1970s. The large quilt visualizes the official count of 9,000 missing persons in the shape of a headscarf worn by their mothers and grandmothers, while the overall dimensions of the quilt acknowledges 30,000 missing persons. The quilt and accompanying missing persons posters encourage the viewer to interact with the data, however the observed reluctance to engage influenced the direction of this discussion about the hegemonic disinclination to get involved when authority figures 'disappear' fellow residents of our communities.

The Density Distribution Of The Material Around Betelgeuse, Iman Behbehani

Dissertations, Theses, and Capstone Projects

Betelgeuse is a red supergiant star visible in the constellation Orion. Its windy and highly convective surface results in a complicated mass loss pattern difficult to understand and replicate in simulations. The ejected mass can form a shell around the star we consider the circumstellar material (CSM). In this study, we use ALMA interferometric observations to find the structure of Betelgeuse's CSM, and connect to the mass loss mechanisms that could form it. We measure a bipolar circumstellar structure with a position angle of 42.3$\pm 7.0^\circ$. We observe asymmetries in the form of hot spots in the north east of …

“Justice, Justice Pursue”: Coworker Reactions To Religious Workplace Accommodations, Joshua A. Nagel

Dissertations, Theses, and Capstone Projects

This study examines coworker reactions to religious accommodations in the workplace, a growing necessity as religious diversity increases, and recent legislation strengthens protections for religious observances. Religious accommodations can provoke perceptions of differential treatment, impacting coworker morale, cooperation, and organizational cohesion. While extensive research exists on disability accommodations, religious accommodations differ fundamentally as they often relate to moral beliefs and are viewed variably in terms of necessity and controllability. Drawing on organizational justice theories, this dissertation applies and modifies Colella’s (2001) and Colella et al.’s (2004) models for coworker perceptions of distributive and procedural fairness of disability accommodations to the …

The Spaces Between: A Phenomenological Exploration Of Classical Music Performance Practice, Fifi Zhang

Dissertations, Theses, and Capstone Projects

In his theory of duration, the philosopher Henri Bergson (1859-1941) asserts that the present moment is “both a perception of the immediate past and a determination of the immediate future…a joint system of sensations and movements.” In an ideal musical performance, this sensori-motor apparatus guides every one of the performer’s decisions on stage, resulting in an aural experience that is spontaneous, visceral, and deeply personal. In practice, much of today’s classical music performance culture, which relies heavily on visual notation and prioritizes fidelity to the composer’s intent, is antithetical to fundamental artistic values such as creativity, individual self-expression, and direct …

Origin And Maintenance Of The Andean Bird Fauna, Elkin A. Tenorio

Dissertations, Theses, and Capstone Projects

The origin and maintenance of the tropical montane diversity have been evaluated over multiple decades using various techniques and perspectives. Despite major progress in understanding phylogenetic relationships, diversification patterns, distributional data, and general ecology in the Andean biota, large gaps in our understanding remain, particularly in the synthesis across scales. To fill these gaps, I aimed to explore patterns and processes that underlie species diversification in birds of the tropical Andes of South America by combining different approaches using phenotypic, phylogenetic, and genomic data in multiple temporal and spatial scales.

In the first chapter, I examined the macroevolutionary patterns of …

The Interaction Of Multilingualism And Depressed Mood On Cognitive Set-Shifting, Annalise Caviasco

Dissertations, Theses, and Capstone Projects

Although findings are mixed, many researchers believe there are cognitive benefits to multilingualism, a phenomenon dubbed the “bilingual advantage”. Of these apparent benefits, cognitive flexibility, or the ability to shift thinking styles based on the context or specific demands of a certain situation, is thought to be highly relevant. Current literature suggests that one aspect of multilingualism, the practice of “code-switching” between languages throughout their daily lives, is related to increased general cognitive flexibility compared to monolinguals. Another branch of research on cognitive flexibility investigating the role of affect in cognition demonstrates that clinical depression as well as transient negative …

Nonlinear Diffusion, Hydrodynamic Cascades And Jamming In Kinetically Constrained Systems: Insights From Lattice Gas Models, Abhishek Raj

Dissertations, Theses, and Capstone Projects

This dissertation investigates non-linear diffusion processes and emergent dynamical phenomena in kinetically constrained lattice gases. Two central models are considered: a one-dimensional lattice gas exhibiting a diffusion cascade triggered by hydrodynamic nonlinearities and a triangular ladder exclusion model that undergoes a jamming transition. The former demonstrates stretched exponential decay consistent with non-perturbative long-time tails, while the latter illustrates how classical-quantum mappings yield insight into glassy dynamics and mobility constraints. Through a combination of numerical simulations, analytical perturbation theory, and mean-field approximations, the work uncovers mechanisms underlying anomalous transport, jamming transitions, and the breakdown of perturbative hydrodynamics.

Performance Practice As Compositional Style: Wet Ink’S Collaborative Work, Carrie Frey

Dissertations, Theses, and Capstone Projects

In its twenty-five years in New York City’s new music scene, Wet Ink Ensemble has established a distinctive approach in which members blend the roles of performer, composer, and improviser. This dissertation investigates how the ensemble’s beginnings at the nexus of the experimental rock and avant-garde music scenes prepared it for a turn towards collaborative composition and improvisation. After defining essential elements of the ensemble’s performance practice, I analyze Eric Wubbels’ Auditory Scene Analysis (I) and Sam Pluta’s Lines on Black—compositions that exemplify opposing poles of notational specificity. I then trace the defined elements through two “Performance Practice” works, …

The Effect Of Tbi On Working Memory And Anxiety In Rats, Mariola Sobolewska

Dissertations, Theses, and Capstone Projects

Traumatic Brain Injury (TBI) is a significant public health concern, often leading to cognitive and emotional impairments. This study examined the effects of TBI on working memory and anxiety-like behavior in young male Sprague-Dawley rats using the Radial Arm Maze (RAM) and Elevated Plus Maze (EPM), which are behavioral assessments. The RAM tests spatial working memory by evaluating the animal’s ability to remember and efficiently navigate multiple arms to retrieve rewards. The EPM assesses anxiety-like behavior based on the animal’s preference for open versus closed arms. The study utilized young male Sprague-Dawley rats, a well-established rodent model known for its …

The Architecture Of Exclusion: Disability, Race, And The History Of New York City’S 600 Schools, Francine Almash

Dissertations, Theses, and Capstone Projects

This dissertation investigates the largely erased history of New York City’s 600 schools—segregated public schools created to house students labeled as emotionally disturbed or socially maladjusted. These institutions, operating throughout the mid-20th century, disproportionately served Black and Puerto Rican youth, many of whom were placed in these schools under vague behavioral criteria and with little to no pathway for return to general education settings.

Combining archival research, longitudinal policy analysis, historical media review, and critical race and disability studies frameworks—including DisCrit (Disability Critical Race Theory)—this project situates the 600 schools at the intersection of institutional racism and ableism. It argues …

Text-Based Propaganda Detection, Vivek Sharma

Dissertations, Theses, and Capstone Projects

In the digital age, the swift consumption of news and the widespread dissemination of propaganda significantly threaten democratic principles and informed decision-making. News organizations, often aligned politically, tailor their content to appeal to specific audiences, thereby perpetuating biases. Despite advancements in detecting propaganda through various computational techniques, including Large Language Models(LLM) and BERT-based approaches, significant challenges persist concerning data availability and the effectiveness of detection tools. This thesis explores the landscape of text-based propaganda and reviews related research in textual analysis. It introduces a novel method for collecting a social-media based dataset, which includes analysis of journalists' tweets to discern …

Online Resources For Oral Communication Courses, Sean P. Palmer

Dissertations, Theses, and Capstone Projects

Online resources focusing on oral communication skills are lacking, even as online education itself expands. While I was aware of this lack, I didn’t realize its severity until LaGuardia Community College went fully remote during the 2020 global pandemic, and I was looking for online tutoring aids for oral communication. Furthermore, the information presented online is frequently unsuitable for the purposes of online pedagogy due to its specialized and jargony mode of presentation. Also, many existing assignments involving oral communication assume public speaking as the default model, despite the growing importance of emergent digital modes of oral performance, like podcasting …

Between The Buffer And The Black Box: Ed(1), Invisible Text, And Delegation In Word Processing, Kai Prenger

Dissertations, Theses, and Capstone Projects

This thesis provides a media archaeological and theoretical examination of ed(1), the Unix line editor developed by Ken Thompson at Bell Labs in 1969, arguing that its approach to "invisible text" processing established lasting patterns of human-computer collaboration that persist in contemporary digital systems. Through historical research, technical analysis, and critical interpretation, this study demonstrates how ed(1) embodied a particular epistemology of text processing that appears alien in a contemporary context, but proves insightful in the age of generative text creation.

ed(1) emerged from the unique convergence of Bell Labs' collaborative research culture, severe hardware constraints of early Unix systems, …

Bmp Signaling Co-Regulation Of Immune Response And Lipid Metabolism, Katerina K. Yamamoto

Dissertations, Theses, and Capstone Projects

The Bone Morphogenetic Proteins (BMPs) are secreted peptide ligands of the Transforming Growth Factor beta (TGF-β) family, initially identified for their roles in development and differentiation across animal species. They are now increasingly recognized for their roles in physiology and infectious disease. In the nematode Caenorhabditis elegans, the BMP ligand DBL-1 controls fat metabolism and immune response, in addition to its roles in body size regulation and development. DBL-1 regulates classical aspects of innate immunity, including the induction of anti-microbial peptides. We theorized that BMP-dependent regulation of fat metabolism could also promote resilience against microbial pathogens. We found that …

Detecting Sonic Hedgehog Expression In The Adult Mouse Brain Using A Gene Expression Tracer, Kendra Stephens-Jones

Dissertations, Theses, and Capstone Projects

Sonic Hedgehog (Shh) is best known for its role in development, yet evidence supports Shh signaling plays a functional role in the adult brain. Previous work demonstrated that Shh is expressed by dopamine (DA) neurons in the ventral midbrain and that loss of Shh from these neurons leads to late-onset motor and structural abnormalities resembling Parkinson’s disease. However, the extent of Shh expression and its connectivity to the striatum in the adult mouse brain remain unclear due to the lack of reliable antibodies for Shh detection. To address this gap, the present study employed Shh ^L/L and DAT-Cre^+/- mice …

Inhibition Of Return And Attentional Blink: Aspects Of A Singular Attentional Process?, Kathleen Rowe

Dissertations, Theses, and Capstone Projects

Inhibition of Return (IOR) and Attentional Blink (AB) are two distinctly defined phenomena that display some intriguingly similar properties. They both describe suppression effects following a visual stimulus that has captured attention, both may be preceded by an enhancement, and both share partially overlapping effect time windows which can be manipulated by task difficulty. The current study attempted to measure the two phenomena simultaneously to test our hypothesis that behavioral indices of AB and IOR will display significant spatial and temporal overlap, suggesting the two phenomena may reflect, at least in part, different aspects of a singular attentional process. To …

Re-Envisioning Digital Agency: From Representationalism To Interpretant-Driven Epistemology, Michael C. Lee

Dissertations, Theses, and Capstone Projects

This thesis examines the epistemological and ethical foundations of digital technologies, particularly code and algorithmic systems, by considering their entanglement with representationalism. Arguing that code now functions as a dominant social agent and epistemic subject, through the concept of the Code’s-eye view, I explore how automated datafication reduces human experience to quantifiable inputs, reinforcing epistemic closure and social fragmentation. Drawing on pragmatist philosophy, including Peirce’s semiotics, Dewey’s democratic ethics, and Rorty’s conversational inquiry, I propose an interpretant-driven epistemology grounded in communal inquiry and interpretive openness. This alternative framework resists the binary logic of algorithmic rationality by emphasizing conflict and the …

Flotsam And Jetsam: The Role Of Mlb Integration In The Wreckage Of The Negro Leagues, Nastasia Pollas

Dissertations, Theses, and Capstone Projects

“We are the ship, all else the sea.” Adapted from a Frederick Douglass speech, this quote by Rube Foster became the slogan of the Negro Leagues, illustrating the resolve and determination to prosper alone during a time of segregation. Setting aside long-standing rivalry and strife, Black baseball teams united under a shared vision of forming the first professional Black baseball league.

This paper examines how Giddens' structuration theory, connecting social structures with individual actions, can explain both the development and success of the league under segregation and its eventual demise during integration.

Unveiling The Precision Of Physiological Signals In Prediction Error During Fear Learning: Insights From Associative Strength And Generalized Uncertainty, Haja H. Jallo-Jamboria

Dissertations, Theses, and Capstone Projects

Prediction error (PE) is the discrepancy between expected and actual outcomes. It is a central mechanism in associative learning particularly within fear-conditioning paradigms. Identifying physiological markers of PE in aversive contexts has important implications for refining learning models and enhancing clinical interventions for anxiety-related disorders. This study examined skin conductance response (SCR) as a potential physiological index of PE by analyzing both anticipatory and omission-related responses across multiple learning phases. Participants completed a Pavlovian fear-conditioning paradigm in which two conditioned stimuli (CS+) signaled threat at different reinforcement probabilities: CS+100 (certain threat) and CS+50 (uncertain threat), alongside a non-reinforced safety cue …
