The Tancredo Martínez Assassination Attempt: Frances Grant And Communistic Discourses, Nelson Santana

Publications and Research

The Trujillato (1930-1961) spanned almost four decades, in part, due to a series of tools and mechanisms centered around Trujillo’s influences and networks outside of the Dominican Republic. Trujillo’s international network of spies made it possible for the Trujillato to identify and keep tabs on anyone who threatened Trujillo’s reign. Thus, Trujillo’s tentacles extended beyond the Dominican Republic and into nations and territories such as Costa Rica, Cuba, Mexico, Puerto Rico and the United States. In order to combat Trujillo’s network, Dominican exiles embraced non-Dominican allies to combat Trujillo’s tentacles.

Instructors Reflect On How Their Preservice Preparation And Ongoing Professional Development Prepared Them To Address Oppressive Dynamics In Adult Esol Programs In The United States, David A. Housel

Publications and Research

For decades, researchers have asserted that the preservice preparation for instructors of adult emergent bi/multilingual learners (EBLs) in the United States can be inconsistent, and access to ongoing professional development (PD) can be insufficient to address the demands of the 21st century classroom. A previous study conducted by the author revealed that instructors of adult EBLs felt adequately prepared to teach English, but they often felt ill-equipped to address the learning challenges and oppressive dynamics that might manifest in their adult English to Speakers of Other Language (ESOL) classrooms. This convergentmixed methods studywas a preliminary attempt to address these issues. …

Implementing A Chatbot On A Library Website, Michelle Ehrenpreis, John P. Delooper

Publications and Research

A library’s website is a virtual point of contact for interacting with its patrons. Ensuring a library’s website has easily findable content is critical for providing access to library resources and highlighting services and events. One tool for assisting with content findability is a chatbot, a form of artificial intelligence software. In this case study, Lehman College's Leonard Lief Library implemented Ivy, a proprietary educational software chatbot on its website, the first of its kind for an academic library. This chatbot functioned as a new tool that assisted users seeking information and provided insight to librarians about the kinds of …

What Can Aphasia Tell Us About How The First-Acquired Language Is Instantiated In The Brain?, Mira Goral

Publications and Research

Recent neurolinguistic theories converge on the hypothesis that the languages of multilingual people are processed as one system in the brain. One system for the multiple languages is also at the core of a translanguaging framework of multilingualism—a framework that focuses on each speaker’s complete linguistic repertoire rather than on the separate languages they know. However, evidence from neuroimaging studies suggests at least some nonoverlapping activations of the first-acquired language (L1) and other (non-L1) languages of multilingual people, especially when the age of acquisition and/or levels of proficiency differ across the languages. Neurolinguistic studies of acquired language disorders have demonstrated …

We Are Having This Conversation Now: The Times Of Aids Cultural Production (Introduction And Timeline 1), Alexandra Juhasz, Theodore Kerr

Publications and Research

This is a book about the history, present, and future of the cultural production of AIDS. It takes the form of thirteen short conversations between two AIDS activists, Alex and Ted, whom you will get to know more as you go along. The book focuses on what we call the Times of AIDS. All this talk is inspired by our longtime AIDS activism and is initiated by looking at related cultural production: objects like AIDS activist videos; events like protests; spaces like AIDS memorials; ideas we have learned from within and outside our community; and through our own memories and …

Estructura Urbana Del Área Metropolitana De Guadalajara, 1999-2019: Un Análisis De Subcentros De Empleo, David López-García, David Gómez-Álvarez

Publications and Research

Resumen

Este estudio explora la evolución de la estructura urbana del Área Metropolitana de Guadalajara (AMG) entre 1999 y 2019. A través de un análisis de doble umbral se identifican nueve subcentros de empleo en 1999 y 14 en 2019, y se analiza su tamaño, estructura espacial y especialización económica. El cálculo de un índice de primacía demuestra que el AMG tiende hacia el monocentrismo. Si bien el AMG ha logrado la aparición de nuevos subcentros de empleo, éstos se agrupan en el espacio para conformar lo que se podría denominar “la gran aglomeración central del AMG”. Por último, se …

Technical Note: Novel Estimates Of The Leaf Relative Uptake Rate Of Carbonyl Sulfide From Optimality Theory, Georg Wohlfahrt, Albin Hammerle, Felix M. Spielmann, Florian Kitz, Chuixiang Yi

Publications and Research

In order to estimate the gross primary productivity (GPP) of terrestrial ecosystems from the canopy uptake of carbonyl sulfide (COS), the leaf relative uptake rate (LRU) of COS with respect to carbon dioxide needs to be known a priori. Currently, the variability of the LRU between plant species in different biomes of the world is poorly understood, making the choice of an appropriate LRU uncertain and hampering further progress towards developing COS as an alternative tracer of GPP. Here we propose a novel approach for estimating LRU based on plant optimality principles, validate it against in situ leaf gas exchange …

“Islamization” And Crackdown In Ningxia: Another Xinjiang?, Yan Sun

Publications and Research

Since late 2016, Ningxia has drawn attention as a new target in Beijing’s drive to “Sinicize Islam.” The removal of overt signs of the Islamic faith and Arab influences is viewed as representing a new front in the CCP’s sweeping rollback of religious freedom. Is Ningxia another Xinjiang as both the party and its critics fear? This paper argues that it is not at the empirical level but shares with Xinjiang key underlying dynamics at the systemic level. At the empirical level, Ningxia’s “Islamization” stemmed largely from local authorities’ use of the Islamic part of Ningxia’s heritage as a developmental …

Satellite Evidence Of Canopy-Height Dependence Of Forest Drought Resistance In Southwestern China, Peipei Xu, Wei Fang, Tao Zhou, Hu Li, Xiang Zhao, Spencer Berman, Ting Zhang, Chuixiang Yi

Publications and Research

The frequency and intensity of drought events are increasing with warming climate, which has resulted in worldwide forest mortality. Previous studies have reached a general consensus on the size-dependency of forest resistance to drought, but further understanding at a local scale remains ambiguous with conflicting evidence. In this study, we assessed the impact of canopy height on forest drought resistance in the broadleaf deciduous forest of southwestern China for the 2010 extreme drought event using linear regression and a random forest (RF) model. Drought condition was quantified with standardized precipitation evapotranspiration index (SPEI) and drought resistance was measured with the …

An Optimal Lysis Time Maximizes Bacteriophage Fitness In Quasi-Continuous Culture, Sherin Kannoly, Abhyudai Singh, John J. Dennehy

Publications and Research

Optimality models have a checkered history in evolutionary biology. While optimality models have been successful in providing valuable insight into the evolution of a wide variety of biological traits, a common objection is that optimality models are overly simplistic and ignore organismal genetics. We revisit evolutionary optimization in the context of a major bacteriophage life history trait, lysis time. Lysis time refers to the period spanning phage infection of a host cell and its lysis, whereupon phage progenies are released. Lysis time, therefore, directly determines phage fecundity assuming progeny assembly does not exhaust host resources prior to lysis. Noting that …

Contesting Imagined Communities: Minor Feelings, Opacity, And Spectrality In Ling Ma’S Severance, Christine Marks

Publications and Research

This article foregrounds pandemic fiction’s subversive and visionary potential through the example of Ling Ma’s dystopian pandemic novel Severance (2018). Emphasizing fiction’s capacity for symbolic intervention in a pandemic era, I argue that the text undermines tropes of nation-building through strategic employment of minor feelings, opacity, and spectral liminality. My analysis focuses on the Chinese American protagonist’s conflicted relationship with imagined communities forged in the conventional “outbreak narrative” (Wald) as her unhomely positionality places her at odds with unifying ideological responses to the catastrophic upheaval of the pandemic. At the intersection of pandemic and diasporic literature, Ma’s novel constitutes a …

We Are Having This Conversation Now: The Times Of Aids Cultural Production (Introduction And Toc & 3 Timelines), Alexandra Juhasz, Theodore Kerr

Publications and Research

We Are Having This Conversation Now offers a history, present, and future of AIDS through thirteen short conversations between Alexandra Juhasz and Theodore Kerr, scholars deeply embedded in HIV responses. They establish multiple timelines of the epidemic, offering six foundational periodizations of AIDS culture, tracing how attention to the crisis has waxed and waned from the 1980s to the present. They begin the book with a 1990 educational video produced by a Black health collective, using it to consider organizing intersectionally, theories of videotape, empowerment movements, and memorialization. This video is one of many powerful yet overlooked objects that the …

“’We Know What We Are, But Not What We May Be’: Student Transformation Through Commentary Blogs", Cheryl Hogue Smith

Publications and Research

This chapter discusses how, when students follow the online discussion practices of Sheridan Blau's Commentary Project, they can learn to embrace confusion, value questions, recognize that uncertainty is part of the learning process, and accept that what they don’t understand is often more important for them as a learner than what they do.

My Phone Lies To Me: Fake News Poetry Workshops As Radical Digital Literacy, Alexandra Juhasz

Publications and Research

This book of poems about fake news written by diverse project participants is foremost an invitation and invocation for readers to participate, with others, in an experiment in knowing and working differently with the internet: Fake News Poetry Workshops. Between 2018 and 2020, Alexandra Juhasz directed more than twenty of these workshops around the world, and these are ongoing beyond the confines of this book. Each differs in form and structure, but participants are always asked to attend to research, their own knowledge about the internet and social media, and what they can learn from their workshop and previous ones

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 …

Relationship Between Intergenerational Mobility (Igm) And Economic Growth: Evidence From Cross-Country Data, Swapnil Landge

Publications and Research

Inequality of opportunity (IGM) is a major cause of inequality of opportunity in many countries. However, the impact of IGM on economic growth has not been fully explored. In this research project, I first replicated and extended the IMF working paper titled IGM, IGM, and Economic Growth’ by Shekhar Aiyar and Christian Ebeke (2019), which explored the relationship between income inequality and economic growth, utilizing various measures of intergenerational mobility, to confirm that the adverse impact of income inequality on growth is more pronounced when IGM is lower. Then, I used the latest Gini dataset (All the Ginis’) compiled by …

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.

“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 …

Finally, I outline some of the potential pitfalls of this course. My aim is to privilege students’ discovery, negotiation, and ownership of ideas. As a …

¿Qué Es Un Campesino? ¿Qué Son Los Campesinados? Un Breve Documento Sobre Cuestiones De Definición, Marc Edelman

Publications and Research

En muchos (aunque no todos) los instrumentos internacionales de derechos humanos, el artículo 1.º se utiliza para definir a los titulares de derechos. Las precisiones normativas de este tipo pueden ser controversiales —por ejemplo, en debates sobre quién es un “niño” en el periodo previo a la Convención sobre los Derechos del Niño—, pero también puede serlo su ausencia (como ocurrió con la Declaración sobre los Derechos de los Pueblos Indígenas). La pregunta de cómo definir campesino y campesinado tiene una historia larga, complicada y polémica. Las definiciones de los grupos humanos surgen o son creadas con diferentes propósitos, incluyendo …

Emphasizing The Economic: Nancy Fraser, The Cultural-Redistributive Divide, And Social Justice’S Pr Crisis, Michael Kirby

Publications and Research

The philosopher Nancy Fraser defines two paradigms for social justice: the economic and the cultural. These two paradigms often find themselves at odds (the familiar struggle between class politics and identi- ty politics), but only when working in conjunction, according to Fraser, can they reach their emancipatory potential. Contra Fraser, this paper argues that there exist some historical moments in which it is neces- sary for one paradigm to take precedence over the other. In our current political moment, both the Right and the Left can be said to be fixated on culture, and this fixation ultimately disadvantages the Left: …

Allocative Efficiency Of Grid Farming In Urban Green Built Environments, Aaryan Manoj Nair

Publications and Research

As of a 2019 study conducted by the National Urban Gardening Program (National Urban Gardening Program), urban farming accounts for approximately 19% of the total national farming output and is expected to triple to almost 45% by 2025. There is intensive research being conducted on aspects of reduced recidivism, communal health benefits, natural carbon capture systems, improved urban ecology and the necessity for reducing the carbon footprint of food, (informally dubbed “food miles”) there is little substantive research on optimization, and maximation of crop productivity in hyper-urban areas. The article attempts to study allocative efficiency in hyper urban built environments.

Classroom Management #Karen: What Can Educators Learn From A Meme?, Sherry L. Deckman, Lizette Aguilar

Publications and Research

Much has been written about how race and the demographic mismatch of mostly white teachers teaching mostly Black and brown students has contributed to the over-disciplining of this same population of students. Further, research has shown that when students have teachers of the same race they are less likely to experience exclusionary discipline practices. While recent studies have considered the role of gender, along with race, in school discipline, the focus remains primarily on the gender and race of the students, with fewer studies considering specifically what it might mean for school discipline that U.S. teachers are mostly white women. …
