Black Feminist Citational Praxis And Disciplinary Belonging, Bianca C. Williams

Publications and Research

What does a Black feminist citational practice look and feel like? This contribution to the #CiteBlackWomen colloquy focuses on two arguments: First, that Black feminist citational praxis is one of the major interventions Black women scholars contribute to the academy; and second, that anthropology’s neglect and erasure of Black feminist anthropologists relates to disciplinary (un)belonging. I explore how citation and “disciplinary belonging” influence hiring practices, doctoral training, intellectual genealogies, and what is valued as anthropological knowledge.

For Critical Language Awareness And Against The “Exclusive-Use-Of-The-Target-Language” Myth: The Effects Of Sociolinguistic Content In English In An Elementary Spanish Classroom, Beatriz Lado, José Del Valle

Publications and Research

Scholars have advocated for critical approaches to language education (e.g., Del Valle, 2014; Leeman & Serafini, 2016), including those that promote the development of Critical Language Awareness, CLA (e.g., Alim, 2010; Leeman, 2018). The goal is to develop students’ critical knowledge of the cultural, political, and social dimensions of language. To this end, Del Valle (2014) suggests the inclusion of language-related content units taught in the first or shared language from the early stages of language learning. This proposal entails revising strong beliefs such as the use of the non-target language in the new language classroom. The purpose of our …

Non-Physician’S Challenges In Sexual And Reproductive Health Care Provision For Women Of Reproductive Age With Cancer: A Scoping Review Of Barriers And Facilitators, Qi Chen, Emma Carpenter, Kari White

Publications and Research

Purpose: The American Society of Clinical Oncology Clinical Practice guidelines recommend that non-physicians such as nurses, social workers, psychologists should be prepared to discuss fertility and sexual concerns with patients. However, literature showed that the utilization rate of sexual and reproductive care for women with cancer remained low. We conducted a scoping review to describe non-physicians’ roles, barriers and facilitators providing sexual and reproductive health (SRH) care to women of reproductive age with cancer.

Methods: We searched six databases for articles that met the following criteria: 1) English-language; 2) original research; 3) non-physician providers; 4) women with cancer under …

Spin(7) Orientifolds And 2d N = (0, 1) Triality, Sebastían Franco, Alessandro Mininno, Ángel M. Uranga, Xingyang Yu

Publications and Research

We present a new, geometric perspective on the recently proposed triality of 2d N = (0, 1) gauge theories, based on its engineering in terms of D1-branes probing Spin(7) orientifolds. In this context, triality translates into the fact that multiple gauge theories correspond to the same underlying orientifold. We show how Spin(7) orientifolds based on a particular involution, which we call the universal involution, give rise to precisely the original version of N = (0, 1) triality. Interestingly, our work also shows that the space of possibilities is significantly richer. Indeed, general Spin(7) orientifolds extend triality to theories that can …

Bft2: A General Class Of 2d N = (0, 2) Theories, 3-Manifolds And Toric Geometry, Sebastían Franco, Xingyang Yu

Publications and Research

We introduce and initiate the study of a general class of 2d N = (0, 2) quiver gauge theories, defined in terms of certain 2-dimensional CW complexes on oriented 3- manifolds. We refer to this class of theories as BFT₂’s. They are natural generalizations of Brane Brick Models, which capture the gauge theories on D1-branes probing toric Calabi-Yau 4-folds. The dynamics and triality of the gauge theories translate into simple transformations of the underlying CW complexes. We introduce various combinatorial tools for analyzing these theories and investigate their connections to toric Calabi-Yau manifolds, which arise as their …

2d N = (0, 1) Gauge Theories And Spin(7) Orientifolds, Sebastían Franco, Alessandro Mininno, Ángel M. Uranga, Xingyang Yu

Publications and Research

We initiate the geometric engineering of 2d N = (0, 1) gauge theories on D1-branes probing singularities. To do so, we introduce a new class of backgrounds obtained as quotients of Calabi-Yau 4-folds by a combination of an anti-holomorphic involution leading to a Spin(7) cone and worldsheet parity. We refer to such constructions as Spin(7) orientifolds. Spin(7) orientifolds explicitly realize the perspective on 2d N = (0, 1) theories as real slices of N = (0, 2) ones. Remarkably, this projection is geometrically realized as Joyce’s construction of Spin(7) manifolds via quotients of Calabi-Yau 4-folds by antiholomorphic …

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 …

Exploratory Programming In The Arts And Humanities [Book Review], Kelly Hammond

Publications and Research

Exploratory Programming is a testament to what open-access can mean, especially in an e-learning environment. Used in full, it is a free course (that relies on free and open software) from a gifted MIT professor whose pedagogy is clear in structure and tone. He scaffolds, promotes predictive thinking, lauds collaborative learning, and urges readers to do not just to read. Used in part, it can be equally powerful.

Quark And Gluon Entanglement In The Proton On The Light Cone At Intermediate X, Adrian Dumitru, Eric Kolbusz

Publications and Research

In QCD with $N_c$ colors the antisymmetric valence quark color space singlet state $\sim \epsilon_{i_1\cdots i_{N_c}} |i_1,\cdots, i_{N_c}\rangle$ of the proton corresponds to the reduced density matrix $\rho_{ij}=(1/N_c) \delta_{ij}$ for a single color degree of freedom. Its degenerate spectrum of eigenvalues, $\lambda_i=1/N_c$, the purity $\tr \rho^2 = 1/N_c$, and the von Neumann entropy $S_\mathrm{vN}=\log(N_c)$ all indicate maximal entanglement of color. On the other hand, for $N_c\to\infty$ the spatial wave function of the proton factorizes into valence quark wave functions determined by a mean field [E. Witten, Nucl. Phys. B160, 57 (1979)] where there is no entanglement of spatial degrees of …

Factors Associated With Mask Use In New York City Neighborhood Parks During The Covid-19 Pandemic: A Field Audit Study, Lisa Hitch, Marie A. Sillice, Hanish Kodali, Katarzyna E. Wyka, Javier Otero Peña, Terry Tk Huang

Publications and Research

Background: Mask use is a cost-effective measure to decrease COVID-19 transmission. Mask mandates intend to increase mask compliance but are often ambiguous when it comes to public outdoor spaces.

Methods: We used a field audit study to examine mask use in New York City neighborhood parks during COVID-19. 1453 park visitors were observed in 13 parks during July–August 2020 using a modified and validated park use audit tool (System for Observing Play and Recreation in Communities) that included items on general and proper mask use (i.e., mask covering both nose and mouth). Generalized estimating equation regression was used to determine …

Perspectives On Determinism In Quantum Mechanics: Born, Bohm, And The 'Quantal Newtonian' Laws, Viraht Sahni

Publications and Research

Quantum mechanics has a deterministic Schrödinger equation for the wave function. The Göttingen-Copenhagen statistical interpretation is based on the Born Rule that interprets the wave function as a ‘probability amplitude’. A precept of this interpretation is the lack of determinism in quantum mechanics. The Bohm interpretation is that the wave function is a source of a field experienced by the electrons, thereby attributing determinism to quantum theory. In this paper we present a new perspective on such determinism. The ideas are based on the equations of motion or ‘Quantal Newtonian’ Laws obeyed by each electron. These Laws, derived from the …

Engagement Et Jeunes De Banlieue : Quand Le Roman Policier Rejoint Le Rap Pour Dire ¨Je Suis Français¨, Iziar De Miguel

Publications and Research

Avec la grande ville au cœur des romans noirs, les activités illégales, les portraits de délinquants, ainsi que de détectives et de flics qui naviguent entre des valeurs morales et amorales prennent place au sein du roman policier. Proposant une image mitigée de la banlieue nord, montrant une culture et des valeurs qui lui sont propres mais aussi ses contradictions et ses malaises, les romans de Rachid Santaki se démarquent du reste de la littérature policière par leur mise en scène de héros issus de l’immigration. Si l’intrigue policière se concentre sur la description de milieux criminels liés au trafic …

Extractable Entanglement From A Euclidean Hourglass, Takanori Anegawa, Norihiro Iizuka, Daniel Kabat

Publications and Research

We previously proposed that entanglement across a planar surface can be obtained from the partition function on a Euclidean hourglass geometry. Here we extend the prescription to spherical entangling surfaces in conformal field theory. We use the prescription to evaluate log terms in the entropy of a conformal field theory in two dimensions, a conformally coupled scalar in four dimensions, and a Maxwell field in four dimensions. For Maxwell we reproduce the extractable entropy obtained by Soni and Trivedi. We take this as evidence that the hourglass prescription provides a Euclidean technique for evaluating extractable entropy in quantum field theory.

Magnetoexcitons In Phosphorene Monolayers, Bilayers, And Van Der Waals Heterostructures, Roman Ya. Kezerashvili, Anastasia Spiridonova, Andrew Dublin

Publications and Research

We study direct and indirect excitons in Rydberg states in phosphorene monolayers, bilayers, and van der Waals (vdW) heterostructure in an external magnetic field within the framework of the effective-mass approximation. The magnetic field is applied perpendicular to the monolayer or heterostructure and is varied between 0 and 60 T. Binding energies of magnetoexcitons are calculated by numerical integration of the Schrödinger equation using the Rytova-Keldysh potential for direct magnetoexcitons and both the Rytova-Keldysh and Coulomb potentials for indirect magnetoexcitons. The latter aids in the understanding of the role of screening in phosphorene. We report the magnetic field energy contribution …

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 …

Large Scale Open Educational Resources (Oer) Initiative In Mathematics, Alioune Khoule, Abderrazak Belkharraz Idrissi, Sandra Sze

Publications and Research

A team of LaGuardia Community College math faculty designed and launched the OER (Open Educational Resources) project in Spring 2017 to allow to take mathematics courses at zero or low textbook cost. Our first pilot phase started with 10 sections in Fall 2017 using three different OER platforms: Myopenmath, Webwork and Khanacademy. One out of the three platforms, Myopenmath used in phase 1 was selected to pilot 34 sections in Spring 2018. In Fall 2018, the OER team moved to a full-scale implementation on all remedial and gateway courses of 164 sections including Fundamentals of Algebra, Intro to Algebra, Elementary …

Beyond "Bad" Cops: Historicizing And Resisting Surveillance Culture In Universities, Amy J. Wan, Lindsey Albracht

Publications and Research

In this article, we define and examine surveillance culture within US college classrooms, a logical extension of pervasive carceral and capitalist logics that underlie the US educational system, in which individual success is tied to behavior monitoring, rule following, and sorting, particularly within marginalized student populations. Reflecting anxieties about the expansion of educational access, we argue for how crisis and change have historically contributed to the
urgency and opportunity to expand surveillance culture and consider why this has continued to happen as a result of the COVID-19 crisis. We offer suggestions and alternatives to surveillance culture that have helped us …

Philosophy In The Narrative Mode: Alexander The Great As An Ethical Character From Roman To Medieval Islamicate Literature, Anna Ayşe Akasoy

Publications and Research

Histories of Arabic and Islamic philosophy tend to focus on texts which are systematic in nature and conventionally classified as philosophy or related scholarly disciplines. Philosophical principles, however, are also defining features of texts associated with other genres. Within the larger field of philosophy, this might be especially true of ethics and within the larger body of literature this might be especially the case for stories. Indeed, it is sometimes argued that the very purpose of storytelling is to reinforce and disseminate moral conventions. Likewise, the moral philosopher can be conceptualized as a homo narrans.

The aim of this …

Notas Para Una Teoría Glotopolítica, José Del Valle

Publications and Research

En este artículo se define la glotopolítica como perspectiva intelectual y se identifican sus posiciones teóricas en relación con el lenguaje. Esta definición, se afirma, supone una apuesta interdisciplinaria en la que la sociolingüística crítica busca activamente establecer relaciones dialógicas con disciplinas tales como la antropología, la filosofía, la historiografía o la sociología. En este sentido, el artículo aborda la visión del lenguaje del crítico literario y cultural galés Raymond Williams, y de las posibilidades metodológicas y teóricas que ofrece su concepto de palabras clave.

This article discusses the theoretical underpinnings of glottopolitical studies, defined as an intellectual perspective. Such …

Regional Topological Aberrances Of White Matter- And Gray Matter-Based Functional Networks For Attention Processing May Foster Traumatic Brain Injury-Related Attention Deficits In Adults, Ziyan Wu, Meng Cao, Xin Di, Kai Wu, Yu Gao, Xiaobo Li

Publications and Research

Traumatic brain injury (TBI) is highly prevalent in adults. TBI-related functional brain alterations have been linked with common post-TBI neurobehavioral sequelae, with unknown neural substrates. This study examined the systems-level functional brain alterations in white matter (WM) and gray matter (GM) for visual sustained-attention processing, and their interactions and contributions to post-TBI attention deficits. Task-based functional MRI data were collected from 42 adults with TBI and 43 group-matched normal controls (NCs), and analyzed using the graph theoretic technique. Global and nodal topological properties were calculated and compared between the two groups. Correlation analyses were conducted between the neuroimaging measures that …

Scarcity Or Economic Insecurity? Two Yardsticks For Measuring Capitalism’S Performance, Costas Panayotakis

Publications and Research

This article argues that capitalism’s relationship to economic insecurity is as important for the evaluation of that system as its relationship to scarcity. Critically analyzing the neoclassical and Marxist focus on capitalism’s relationship to scarcity, the article describes how capitalism’s relationship to economic insecurity offers a more cogent elaboration of these traditions’ shared belief that the economic system should serve people. In particular, while critical of the neoclassical portrayal of capitalism as a system using scarce resources efficiently, this paper also argues, against Marxism, that an alternative to capitalism might be preferable even if scarcity is not abolished.

High-Resolution Cryo-Electron Microscopy Structure Of Photosystem Ii From The Mesophilic Cyanobacterium, Synechocystis Sp. Pcc 6803, Christopher J. Gisriel, Jimin Wang, Jinchan Liu, David A. Flesher, Krystle M. Reiss, Hao-Li Huang, Ke R. Yang, William H. Armstrong, M. R. Gunner, Victor S. Batista, Richard J. Debus, Gary W. Brudvig

Publications and Research

Photosystem II (PSII) enables global-scale, light-driven water oxidation. Genetic manipulation of PSII from the mesophilic cyanobacterium Synechocystis sp. PCC 6803 has provided insights into the mechanism of water oxidation; however, the lack of a highresolution structure of oxygen-evolving PSII from this organism has limited the interpretation of biophysical data to models based on structures of thermophilic cyanobacterial PSII. Here, we report the cryo-electron microscopy structure of PSII from Synechocystis sp. PCC 6803 at 1.93-Å resolution. A number of differences are observed relative to thermophilic PSII structures, including the following: the extrinsic subunit PsbQ is maintained, the C terminus of the …

Cryptococcus Neoformans Melanization Incorporates Multiple Catecholamines To Produce Polytypic Melanin, Rosanna P. Baker, Christine Chrissian, Ruth E. Stark, Arturo Casadevall

Publications and Research

Melanin is a major virulence factor in pathogenic fungi that enhances the ability of fungal cells to resist immune clearance. Cryptococcus neoformans is an important human pathogenic fungus that synthesizes melanin from exogenous tissue catecholamine precursors during infection, but the type of melanin made in cryptococcal meningoencephalitis is unknown. We analyzed the efficacy of various catecholamines found in brain tissue in supporting melanization using animal brain tissue and synthetic catecholamine mixtures reflecting brain tissue proportions. Solid-state NMR spectra of the melanin pigment produced from such mixtures yielded more melanin than expected if only the preferred constituent dopamine had been incorporated, …

A Trauma-Informed Inquiry Of Covid-19’S Initial Impact On Students In Adult Education Programs In The United States, David A. Housel

Publications and Research

The COVID-19 pandemic has had a profound impact on adult education programs throughout the world, abruptly transforming in-person instruction to distance teaching/learning. Can the lessons learned from adult students, especially related to the “digital divide,” be leveraged to enhance adult education and create more inclusive policies and practices moving forward? To grapple with this question, this exploratory qualitative study sought the insights of adult learners in the northeastern United States through an online survey of primarily open-ended questions. Through multiple rounds of coding using a trauma-informed lens, the following themes emerged: (a) anxiety and loss; (b) distractions, adjustments, and balance; …

College Majors And Unemployment Rates, Anna M. Gellerman, Harshita Ahuja

Publications and Research

College undergraduates often face the question of whether their major and related job force have high unemployment rates. The perceived high unemployment rates of certain majors due to circulating misinformation presents a need for comprehensive research on college majors and their associated unemployment rate. This paper dives into a ten year trend of unemployment rates by college major, and state to state variabilities of majors and their rates.
