Workin' Languages: Who We Are Matters In Our Writing, Sara P. Alvarez, Amy J. Wan, Eunjeong Lee

Publications and Research

The steady increase of movements of people around the world has transformed the face, potential, and expectations of the US writing classroom. These intersecting shifts have also contributed to critical discussions about how writing educators should integrate students’ linguistic diversity and ways of knowing into literacy instruction. This chapter’s central premise is to share with students how the work that they already do with languages has great value. Specifically, the chapter introduces terms, concepts, and strategies to support students in identifying how their own multilingual workin’ of languages contribute to the making of academic writing. Our goal is to support …

Do Students’ Questions During Chemistry Lectures Predict Perceived Comprehension And Exam Performance?, Bradley W. Bergey, Jennifer G. Cromley, Avi Kaplan, James D. Bloxton Ii

Publications and Research

Question generation is theorized to support comprehension, self-regulation, and achievement, yet the empirical based for whether and how student-generated questions are associated with comprehension monitoring and whether they predict future performance remain open questions. To address these, we investigated the questions undergraduate students in an introductory chemistry course recorded in question logs across an 8-lecture unit and their relations with post-lecture self-appraisals of comprehension and exam performance. Results indicated that students who generated more questions during lectures, who were able to resolve fewer of their questions, and who generated questions indicating large exam-relevant knowledge gaps reported lower levels of comprehension …

Automatic Cephalometric Landmark Detection On X-Ray Images Using Object Detection, Cheng-Ho King, Yin-Lin Wang, Chia-Ling Tsai

Publications and Research

We propose a new deep convolutional cephalometric landmark detection framework for orthodontic treatment. Our proposed method consists of two major steps: landmark detection using a deep neural network for object detection, and landmark repair to ensure one instance per landmark class. For landmark detection, we modify the loss function of the backbone network YOLOv3 to eliminate the constrains on the bounding box and incorporate attention mechanism to improve the detection accuracy. For landmark repair, a triangle mesh is generated from the average face to eliminate superfluous instances, followed by estimation of missing landmarks from the detected ones using Laplacian Mesh. …

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 …

"The Battle Trumpet Blown!": Whitman's Persian Imitations In Drum-Taps, Roger Sedarat

Publications and Research

While Walt Whitman’s thematic use of the Orient continues to receive critical attention based on his explicit foreign references, aside from observations of specific Persian signifiers in “A Persian Lesson,” his engagement with the poetry of Iran has remained especially speculative and therefore analogical, with studies like J. R. LeMaster and Sabahat Jahan’s Walt Whitman and the Persian Poets showing how his mystical relation to his own religious influences tends to resemble the Sufism of Rumi and Hafez. A new discovery emerging from an examination of his personal copy of William Alger’s The Poetry of the East along with his …

Humidity Reduces Rapid And Distant Airborne Dispersal Of Viable Viral Particles In Classroom Settings, Antun Skanata, Fabrizio Spagnolo, Molly Metz, Davida S. Smyth, John J. Dennehy

Publications and Research

The transmission of airborne pathogens is considered to be the main route through which a number of known and emerging respiratory diseases infect their hosts. While physical distancing and mask wearing may help mitigate short-range transmission, the extent of long-range transmission in closed spaces where a pathogen remains suspended in the air remains unknown. We have developed a method to detect viable virus particles by using an aerosolized bacteriophage Phi6 in combination with its host Pseudomonas phaseolicola, which when seeded on agar plates acts as a virus detector that can be placed at a range of distances away from an …

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.

Infant Motor Development Predicts The Dynamics Of Movement During Sleep, Aaron Demasi, Melissa N. Horger, Anat Scher, Sarah E. Berger

Publications and Research

The characteristics of infant sleep change over the first year. Generally, infants wake and move less at night as they grow older. However, acquisition of new motor skills leads to temporary increases in night waking and movement at night. Indeed, sleep-dependent movement at night is important for sensorimotor development. Nevertheless, little is known about how movement during sleep changes as infants accrue locomotor experience. The current study investigated whether infant sleep and movement during sleep were predicted by infants' walking experience. Seventy-eight infants wore an actigraph to measure physical activity during sleep. Parents reported when their infants first walked across …

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. …

Superluminal Propagation On A Moving Braneworld, Brian Greene, Daniel Kabat, Janna Levin, Arjun S. Menon

Publications and Research

We consider a braneworld scenario in the simplest setting, M₄ × S¹, with a four-dimensional (4D) Minkowski metric induced on the brane, and establish the possibility of superluminal propagation. If the brane is at rest, the 4D Lorentz symmetry of the brane is exact, but if the brane is in motion, it is broken globally by the compactification. By measuring bulk fields, an observer on the brane sees a slice through a higher-dimensional field profile, which carries an imprint of the extra dimensions even when the brane is at rest. If the brane is in motion, we …

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.

La Musique Dans Les Cultures Tech. La Synthèse Modulaire En Temps De Covid-19, Eliot Bates

Publications and Research

Depuis 1996, la synthèse modulaire matérielle est passée d’une pratique artisanale de fabrication d’instruments de niche soutenue par un petit nombre de musiciens, à un phénomène transnational, une véritable culture tech. Malgré cet engouement, elle n’a pas donné naissance à de nouveaux genres musicaux populaires, et il n’est pas certain que la « musique », quelle que soit sa définition, soit ce qui rassemble les amateurs de synthèse modulaire. Ce texte a deux objectifs : tout d’abord, il présente les résultats d’une recherche en cours menée en ligne et dans plusieurs pays concernant le rôle des objets technologiques dans la …

“It Wasn’T Just About Learning How To Speak Spanish”: Engaging Histories Of Oppression And Enslavement In Spanish Heritage Language Education, Tania Avilés, Anthony J. Harb

Publications and Research

We present a curricular intervention in elementary Spanish heritage language in a Hispanic serving institution located in the US Northeast (Bronx, NYC), that aims to contextualize Latinx students’ experiences and perceptions of Blackness within broader histories of oppression and enslavement. Our practice brings together critical Latinx pedagogy and critical approaches to Spanish heritage language education to facilitate sociohistorical consciousness for both language instructors and students through the use of open-access Latinx archival resources. We outline a three-week unit designed using the First Blacks in the Americas online collection curated by the City University of New York Dominican Studies Institute. During …

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 …

Long Covid And Medical Gaslighting: Dismissal, Delayed Diagnosis, And Deferred Treatment, Larry Au, Cristian Capotescu, Gil Eyal, Gabrielle Finestone

Publications and Research

While we know a lot more about Long Covid today, patients who were infected with Covid-19 early on in the pandemic and developed Long Covid had to contend with medical professionals who lacked awareness of the potential for extended complications from Covid-19. Long Covid patients have responded by labeling their contentious interactions with medical professionals, organizations, and the broader medical system as “gaslighting.” We argue that the charge of medical gaslighting can be understood as a form of ontological politics. Not only do patients demand that their version of reality be recognized, but they also blame the experts who hold …

Addressing Gender-Based Violence Using Evidence-Based Practices During Covid-19: The Case Of Puerto Rico, Ayorkor Gaba, Roseanne Flores, María Rebecca Ward, Bailey Pridgen

Publications and Research

As gender-based violence (GBV) surged during the COVID-19 pandemic, the 65th session of the Commission on the Status of Women (CSW65) called for member states, civil, and other stakeholders to consider the specific needs of women and girls in COVID-19 response and recovery efforts. Psychology provides scientific knowledge to help answer this call. Despite existing global guidance and psychological research to mitigate GBV, COVID-19 presents new challenges for consideration. This article summarizes existing GBV guidance/research and COVID-19 considerations, uses an illustrative case study to describe Puerto Rico’s application of GBV guidance/research during COVID-19, and provides preliminary policy and practice recommendations.
