After The Cambridge Controversies: Reflections Old And New, Harvey Gram

Publications and Research

Perfect foresight is a consequence of applying the Pontryagin Maximum Principle to the analysis of an intertemporal general equilibrium. For this reason, the capital theory controversy ended in an intellectual impasse. The critique of mainstream theory largely ignored the perfect foresight entailments of intertemporal equilibrium analysis, while its defenders, with notable exceptions, too often failed to acknowledge this implication of the technique of dynamic programming. From this standpoint, the long debate over the existence or non-existence of an aggregate production function is secondary. This leaves open the theoretical question of how to proceed with an analysis of the actual dynamics …

Behavioral Predictive Analytics Towards Personalization For Self-Management – A Use Case On Linking Health-Related Social Needs, Bon Sy, Michael Wassil, Helene Connelly, Alisha Hassan

Publications and Research

The objective of this research is to investigate the feasibility of applying behavioral predictive analytics to optimize patient engagement in diabetes self-management, and to gain insights on the potential of infusing a chatbot with NLP technology for discovering health-related social needs. In the U.S., less than 25% of patients actively engage in self-health management even though self-health management has been reported to associate with improved health outcomes and reduced healthcare costs. The proposed behavioral predictive analytics relies on manifold clustering to identify subpopulations segmented by behavior readiness characteristics that exhibit non-linear properties. For each subpopulation, an individualized auto-regression model and …

Tracking Cryptic Sars-Cov-2 Lineages Detected In Nyc Wastewater, Davida S. Smyth, Monica Trujillo, Devon A.

Publications and Research

Tracking SARS-CoV-2 genetic diversity is strongly indicated because diversifying selection may lead to the emergence of novel variants resistant to naturally acquired or vaccine-induced immunity. To monitor New York City (NYC) for the presence of novel variants, we deep sequence most of the receptor binding domain coding sequence of the S protein of SARS-CoV-2 isolated from the New York City wastewater. Here we report detecting increasing frequencies of novel cryptic SARS-CoV-2 lineages not recognized in GISAID’s EpiCoV database. These lineages contain mutations that had been rarely observed in clinical samples, including Q493K, Q498Y, E484A, and T572N and share many mutations …

A Novel Tropical Geometry-Based Interpretable Machine Learning Method: Pilot Application To Delivery Of Advanced Heart Failure Therapies, Heming Yao, Harm Derkson, Jessica R. Golbus, Justin Zhang, Keith D. Aaronson, Jonathan Gryak, Kayvan Najarian

Publications and Research

Abstract—A model’s interpretability is essential to many practical applications such as clinical decision support systems. In this paper, a novel interpretable machine learning method is presented, which can model the relationship between input variables and responses in humanly understandable rules. The method is built by applying tropical geometry to fuzzy inference systems, wherein variable encoding functions and salient rules can be discovered by supervised learning. Experiments using synthetic datasets were conducted to demonstrate the performance and capacity of the proposed algorithm in classification and rule discovery. Furthermore, we present a pilot application in identifying heart failure patients that are eligible …

Importin-Mediated Pathological Tau Nuclear Translocation Causes Disruption Of The Nuclear Lamina, Tdp-43 Mislocalization And Cell Death, Robert F. Candia, Leah S. Cohen, Viktoriya Morozova, Christopher Corbo, Alejandra D. Alonso

Publications and Research

Tau is a cytosolic protein that has also been observed in the nucleus, where it has multiple proposed functions that are regulated by phosphorylation. However, the mechanism underlying the nuclear import of tau is unclear, as is the contribution of nuclear tau to the pathology of tauopathies. We have previously generated a pathological form of tau, PH-tau (pseudophosphorylation mutants S199E, T212E, T231E, and S262E) that mimics AD pathological behavior in cells, Drosophila, and a mouse model. Here, we demonstrated that PH-tau translocates into the nucleus of transiently transfected HEK-293 cells, but wildtype tau does not. We identified a putative …

Friendship In The Confucian Tradition, Andrew Lambert

Publications and Research

An overview of how friendship has been represented and assessed in the Confucian tradition, and particularly in classical Confucian texts such as the Analects and the Mencius. Themes covered include the relationship between the family and friendship, the ambivalence towards friendship in imperial China, and the connection between friendship and the Confucian ideal of personal cultivation. The chapter finishes by exploring novel conceptions of friendship and human relatedness suggested by the Confucian tradition.

Can Heritage Speakers Predict Lexical And Morphosyntactic Information In Reading?, Olga Parshina, Anastasiya Lopukhina, Irina A. Sekerina

Publications and Research

Ample evidence suggests that monolingual adults can successfully generate lexical and morphosyntactic predictions in reading and that correct predictions facilitate sentence comprehension. In this eye-tracking corpus reading study, we investigate whether the same is true for reading in heritage language. Specifically, we ask whether heritage speakers (HSs) of Russian are able to anticipate lexical and/or morphosyntactic information of the upcoming words in the sentence and whether they differ in the predictions from monolingual children and L2 learners. We are also interested in whether the literacy level (i.e., Russian literacy experience or reading fluency in English) influences lexical and morphosyntactic prediction. …

What Role Does Prior Religious Beliefs Play In Cult Susceptibility: A Descriptive Study, Yasmin Ali

Student Theses

Research on cults has explored susceptibility related to seeking membership, but not the role of an individual’s prior religious beliefs in cult involvement (Almendros et al., 2007). This study aims to understand the role of prior religious beliefs to cult susceptibility—specifically, joining and remaining in a cult. This study explored participants’ prior and subsequent religious affiliations and spirituality. In addition, it investigated the relationship between prior religion type and the cult type joined, including age of induction, time involved, and gender differences.

Former cult members (N=103) of a variety of Christian and non-Christian groups were interviewed using a semi-structured interview …

Defining Entanglement Without Tensor Factoring: A Euclidean Hourglass Prescription, Takanori Anegawa, Norihiro Iizuka, Daniel Kabat

Publications and Research

We consider entanglement across a planar boundary in flat space. Entanglement entropy is usually thought of as the von Neumann entropy of a reduced density matrix, but it can also be thought of as half the von Neumann entropy of a product of reduced density matrices on the left and right. The latter form allows a natural regulator in which two cones are smoothed into a Euclidean hourglass geometry. Since there is no need to tensor factor the Hilbert space, the regulated entropy is manifestly gauge invariant and has a manifest state-counting interpretation. We explore this prescription for scalar fields, …

Two-Loop Four-Fermion Scattering Amplitude In Qed, R. Bonciani, A. Broggio, S. Di Vita, A. Ferroglia, M. K. Mandal, P. Mastrolia, L. Mattiazzi, A. Primo, J. Ronca, U. Schubert, W. J. Torres Bobadilla, F. Tramontano

Publications and Research

We present the first fully analytic evaluation of the transition amplitude for the scattering of a massless into a massive pair of fermions at the two-loop level in quantum electrodynamics. Our result is an essential ingredient for the determination of the electromagnetic coupling within scattering reactions, beyond the currently known accuracy, which has a crucial impact on the evaluation of the anomalous magnetic moment of the muon. It will allow, in particular, for a precise determination of the leading hadronic contribution to the (g − 2)_μ in the MUonE experiment at CERN, and therefore can be used to …

A Template Method To Measure The $T \Bar T$ Polarisation, J. A. Aguilar-Saavedra, M. C. N. Fiolhais, P. Martín-Ramiro, J. M. Moreno, António Onofre

Publications and Research

We develop a template method for the measurement of the polarisation of $t \bar t$ pairs produced in hadron collisions. The method would allow to extract the individual fractions of $t_L \bar t_L$, $t_R \bar t_R$, $t_L \bar t_R$ and $t_R \bar t_L$ pairs with a fit to data, where L, R refer to the polarisation along any axis. These polarisation fractions have not been independently measured at present. Secondarily, the method also provides the net polarisation of t and $\bar t$, as well as their spin correlation for arbitrary axes.

The Octagon At Large M, Riccardo Argurio, Matteo Bertolini, Sebastían Franco, Eduardo García-Valdecasas, Shani Meynet, Antoine Pasternak, Valdo Tatitscheff

Publications and Research

Recently, the first instance of a model of D-branes at Calabi-Yau singularities where supersymmetry is broken dynamically into stable vacua has been proposed. This construction was based on a system of N regular and M = 1 fractional branes placed at the tip of the so-called (orientifolded) Octagon singularity. In this paper we show that this model admits a large M generalization, having the same low energy effective dynamics. This opens up the possibility that the effect on geometry is smooth, and amenable to describing the gauge theory all along the RG flow, including the deep IR, in terms of …

Exchange Rate Forecast Model: Factor Analysis, Swapnil Landge

Publications and Research

Forecasting the exchange rate using factor analysis, factors based on cross section exchange rates of different economies in terms of trade, would beat random walk model in longer out of sample horizon forecasting. In this research project, we will replicate the NBER working paper Factor Model Forecasts of Exchange Rates” by Charles Engel, Nelson C. Mark & Kenneth D. West (2012) which has used 17 OECD countries exchange rates in getting the potential factors but with extended time period from 1973:1-2021:4. We will report early sample forecasting statistics for a 1987-1998 sample. Results for late samples (1999-2022) were promising, at …

Working Knowledge: Catalogers And The Stories They Tell, Amanda Belantara, Emily Drabinski

Publications and Research

Cataloging librarians make myriad choices every day as they create the metadata necessary for information retrieval. Each record represents an interaction between the cataloger and the systems they work within and, sometimes, against. Their work is highly constrained by standardized machine-readable fields and codes, controlled subject terms, and classification schema. In the exploratory research project Catalogers at Work, the authors use sound recording to reveal the complex yet hidden negotiations embedded in library catalog records.

Getting Back: The Chiffons’ Sonic Reclamation, Hilarie Ashton

Publications and Research

Sixties girl group the Chiffons are famous for their soaring 1964 hit “He’s So Fine,” a song in turn remembered almost as often for its plagiarism by George Harrison than in its own right. Much of the rest of their catalogue, including the tremendous “I Have a Boyfriend,” gets shunted into historical and critical gaps that paint rock music history as controlled by men. In this article, I examine the Chiffons in their own right, reframing a story of well-worn sonic theft to center on the group it obscured, through and alongside interpretative contradictions, assumptions, and historical lacunae. I show …

How Do You Meme?: Using Memes For Information Literacy Instruction, Christina Boyle

Publications and Research

Memes, or image macros, have become a standard method of digital information sharing. This is especially true during times when current events ignite a heightened desire for information seeking among students. Memes can be sources of misinformation, such as during events of the past decade, including recent presidential elections, social justice movements such as Black Lives Matter, and the ongoing COVID-19 pandemic. Librarians need to address this format in their information literacy teachings. In this article, the author briefly outlines the rise of internet memes, discusses how higher education students are engaging with them, and highlights some problematic meme-sharing throughout …

Language-Internal Reanalysis Of Clitic Placement In Heritage Grammars Reduces The Cost Of Computation: Evidence From Bulgarian, Tanya Ivanova-Sullivan, Irina A. Sekerina, Davood Tofighi, Maria Polinsky

Publications and Research

The study offers novel evidence on the grammar and processing of clitic placement in heritage languages. Building on earlier findings of divergent clitic placement in heritage European Portuguese and Serbian, this study extends this line of inquiry to Bulgarian, a language where clitic placement is subject to strong prosodic constraints. We found that, in heritage Bulgarian, clitic placement is processed and rated differently than in the baseline, and we asked whether such clitic misplacement results from the transfer from the dominant language or follows from languageinternal reanalysis. We used a self-paced listening task and an aural acceptability rating task with …

Managing Information For Innovation Using Knowledge Integration Capability: The Role Of Boundary Spanning Objects, Chandan Acharya, Divesh Ojha, Rahul Gokhale, Pankaj Patel

Publications and Research

Knowledge Integration (KI) or the capability to collate and process distinctive stocks of organizational information is central to innovation. Although an essential capability, KI is also challenging to accomplish in practice due to relational obstacles. The relational obstacles arise because of knowledge boundaries: (a) syntactic boundary where the challenge is to transfer the knowledge; (b) semantic boundary where the challenge is to translate the knowledge; and (c) pragmatic boundary, where the challenge is to transform the knowledge to realize relational rents. In this paper, we propose that these relational obstacles could be resolved through a common lexicon, common meaning, and …

Satirical Dissent: The Subversive Messaging Of Ad Reinhardt’S 1946 And 1961 Art Comics How To Look At Modern Art In America, Julie A. Schumacher

Dissertations and Theses

Through a close analysis of Ad Reinhard's 1946 and 1961 art comics "How to Look at Modern Art in America,” examined in the context of their times, this paper will argue that Reinhardt’s idealist view and involvement with abstraction, as he saw it in its “purest” form, was intrinsically formed and shaped by his Marxist anticapitalistic perspectives in response to his concurrent time. When these works are examined through the lens of Reinhard’s socialist politics, a parallel narrative surfaces where “pictures artists” also signifies capitalism and its capacity to harmonize and contaminate.

The Night Of The Long Knives: Reconsidered, Edward G. Gunning Jr.

Dissertations and Theses

The "Night of the Long Knives"—June 30, 1934, and the murderous days that followed is one of the more fascinating episodes in the history of the Third Reich. A year after taking power, multiple circles of influence challenged Nazi control. The National Socialists perceived enemies everywhere. At times the internal challenges were as significant as the external.

Much of the conflict centered on a myriad of perspectives on the nature and direction of the Nazi revolution. For Hitler, the revolution was complete, at least for now. His real revolution was a racial one, whose full dimensions only became manifest later. …

Cherokee Abstract Artist Leon Polk Smith: A Convergence Of Traditions, Danielle Montanino

Dissertations and Theses

This paper analyzes how Leon Polk Smith's Indigenous roots and upbringing in Indian Country had a significant impact on his artistic practice in a time of discrimination and segregation in the United States. Through examination contextualizing his work within the history and political events of the Cherokee, Chickasaw, and Choctaw Nations it is revealed how Polk Smith developed a formal language that could navigate both worlds and be viewed through a pure abstraction lens or a lens embodying his Indigenous traditions. In addition to his Indigenous philosophies, Mesoamerican Inca Nation’s cultural motifs further ground Polk Smith’s Indigenous aesthetic, and avant-garde …

Flawed Judgment: The Prolonged Failure Of Handschu V. Special Services Division, 1971-2022, Henry A. Burby

Dissertations and Theses

This thesis explores Handschu v. Special Services Division, an ongoing federal class-action suit brought by New York activists in 1971 to challenge the NYPD's right to use covert tactics to monitor them and undermine their political projects. The Handschu plaintiffs originally hoped that the court would find the NYPD's covert activities unconstitutional and would intervene on behalf of all New Yorkers thus targeted. After the conservative Burger Court challenged the pro-activist decisions of the previous Warren Court, the plaintiffs abandoned their ambitious goals and settled with the defendants. The Handschu defendants easily sidelined this settlement in the wake of the …

As a whole, this work extends contemporary scholarship on ecofeminist engaged art to include Damon’s artistic production while amplifying social and critical ecofeminism as necessary ideologies to explore when analyzing art through an ecofeminist lens. Beginning with her first environmentally focused work in the United States the organization of the following chapters reveals Damon’s deepened understanding and exploration of ecofeminist principles and their application to her artistic practice. It goes on to further explore Damon’s pursuit of environmentally sustainable …

Analysis Of The Influence Of Cryptocurrency Regulation On Levels Of Financial Literacy, Kieran C. Yuen

Dissertations and Theses

Using data collected by the National Financial Capability Study (NFCS), a survey by the Financial Industry Regulatory Authority (FINRA), this paper investigates the influence of passage of cryptocurrency regulation in U.S. states on levels of financial literacy. Results indicate that living in a state where cryptocurrency regulation was signed into law, a decrease was observed in the level of financial literacy. This finding supports the growing literature on factors that affect levels of financial literacy using a novel exogenous variable, cryptocurrency regulation.

African American English As A Predictor Of Ethnic And Ethnolinguistic Identity In Adolescence, Giahna L. Glasco

Dissertations and Theses

This study’s purposes were to provide support for the Social identity theory of African American English (Vietze & Glasco, 2022) and the meanings African American English (AAE) speakers assign to their dialect. The study was primarily based on Tajfel’s (1979) social identity theory that proposes individuals derive a sense of self from group membership. The qualitative analyses examined ethnic and language group memberships. Ethnic identity development (Phinney, 1992), and ethnolinguistic identity theories (Giles and Johnson, 1987) guided narrative and content analyses of Kiese Laymon’s memoir, Heavy: An American Memoir (Laymon, 2018). The sample included 21 African American English conversations …

“I Knew These Marvelous People”: Gay Men’S Experiences Of Long-Term Hiv/Aids Survival, Ilana J. Sichel

Dissertations and Theses

The gay and bisexual men who were diagnosed with HIV/AIDS before the pharmaceutical breakthroughs of the mid-1990s were given what was expected to be a death sentence. Instead, the majority of those who began the newly available treatments outlived not just their initial prognoses but their lovers, friends, and community members who had already perished. This study used grounded theory analysis of semi-structured interviews with a sample of 10 self-identified gay men who are long-term HIV/AIDS survivors to explore experiences of trauma, loss, and mourning in relation to current psychological wellbeing. Qualitative thematic analysis indicated that despite demographic variance among …

Therapeutic Considerations For The Polycule: A Qualitative Exploration Of Consensual Non-Monogamy In Couples Treatment, Tema Watstein

Dissertations and Theses

Despite the growing visibility of consensual non-monogamy culturally and in the academic domain, treatment of CNM relationships has been understudied from the clinical perspective. This study utilized a sample of 11 clinicians, who discussed their experiences of treating non-monogamous couples through a semi-structured interview. Qualitative thematic analysis led to the emergence of robust themes, which were synthesized into three broader categories: 1. Therapeutic Process, 2. Issues in Treatment, and 3. The Meaning of Non-Monogamy. Therapists discussed their own clinical processes, with emphasis on countertransference, frame, self-disclosure, and considerations for training. Themes also emerged surrounding common issues in treatment, ranging from …

Identification Of Adhd And Comorbid Disorders In Children: The Potential Role Of Minority Group Membership, Rachel H. Tayler

Dissertations and Theses

Identification of ADHD and Comorbid Disorders in Children: The potential role of minority group membership

by

Rachel Tayler, MSc, MA

Advisor: Sarah O’Neill, PhD

Attention-Deficit/Hyperactivity Disorder (ADHD) affects six million US children. Females, Latinx, and possibly Black children have lower rates of diagnosis than their Male and White non-Latinx peers. ADHD is behaviorally defined, and as such, clinicians' perceptions of symptoms and determination of diagnoses may be influenced by demographic factors such as race, ethnicity and sex.

This vignette study examined whether clinicians' implicit ethnic, racial, and sex biases affect diagnosis of ADHD and comorbid conditions. Psychiatry trainees and pediatricians …

Covid-19 Vaccine Related Anxiety Partially Mediates The Association Between Covid-19 Related Anxiety And Student Adjustment To College During The Pandemic, Hanh Nguyen

Dissertations and Theses

The COVID-19 pandemic caused severe disruptions to the education of millions of college students, who were forced to adapt to sudden changes in living and learning environments. In this study, we sought to investigate two different dimensions of anxiety that were specific to the pandemic – COVID-19 related anxiety and COVID-19 vaccine anxiety – hoping to pinpoint the relationship between these two variables and students’ ability to adapt to college. Specifically, using cross sectional survey data during three semester waves (Spring 2021, Fall 2021, and Spring 2022) we hypothesized (1) a decreasing trend across time in both COVID-19 related anxiety …
