Weird Winter Weather In The Anthropocene: How Volatile Temperatures Shape Violent Crime, Christopher Thomas, Kevin T. Wolff

Publications and Research

Purpose: Current evidence suggests volatile temperatures are becoming more common because of climate change and can be expected to become even more frequent in the future. By focusing on recent temperature variability, we attempt to estimate one important dimension of the impact of climate change on violent crime. We also explore whether sudden upward temperature anomalies have stronger positive impacts on violent crime in the coldest months of the year, as routine activities are likely to change more drastically during this period.

Methods: This study explores the association between sudden temperature anomalies (both upward and downward) and the daily incidence …

Artificial Intelligence In Neuroradiology: A Scoping Review Of Some Ethical Challenges, Pegah Khosravi, Mark Schweitzer

Publications and Research

Artificial intelligence (AI) has great potential to increase accuracy and efficiency in many aspects of neuroradiology. It provides substantial opportunities for insights into brain pathophysiology, developing models to determine treatment decisions, and improving current prognostication as well as diagnostic algorithms. Concurrently, the autonomous use of AI models introduces ethical challenges regarding the scope of informed consent, risks associated with data privacy and protection, potential database biases, as well as responsibility and liability that might potentially arise. In this manuscript, we will first provide a brief overview of AI methods used in neuroradiology and segue into key methodological and ethical challenges. …

Throughout the early 2000s, the ways in which the World Wide Web was used would undergo major changes. The introduction of these changes around this time period would be collectively known as Web 2.0. With Web 2.0, accessibility and distribution of applications became more simplified. During the 2000s, much has evolved from hard capabilities to the internet and its widespread usage amongst companies and general consumers. In contemporary times, multiple technologies, both hardware and digital are becoming more advanced, with general consumers either rejecting or accepting these gradual shifts in what may become everyday technology. Web 3.0, the theoretical advancement …

The Dialectic Transformation Of Teaching And Learning In Community Colleges Through Ungrading., Grace Pai, Jennifer Corby, Nicole Kras, Dusana Podlucká, Midori Yamamura

Publications and Research

As five Andrew J. Mellon Transformative Learning in the Hu-manities Faculty Fellows in the City University of New York, we capture in this essay the dialectical experience of ungrading our community college courses with our students. Drawing on case examples of implementing un-grading in a range of courses and a thematic analysis of our students’ reflec-tion submissions of being ungraded, we argue that ungrading is an effective pedagogical tool for debunking a deficits-based, outcomes-focused perspec-tive that is pervasive in studies on and of community college students. Through various ways of building student agency, self-reflection, and feed-back into our courses, we …

The Compound Risk Of Heat And Covid-19 In New York City: Riskscapes, Physical And Social Factors, And Interventions, Janelle Knox-Hayes, Juan Camilo Osorio, Natasha Stamler, Maria Dombrov, Rose Winer, Mary Hannah Smith, Reginald Blake, Cynthia Rosenzweig

Publications and Research

Climate change is disrupting the fundamental conditions of human life and exacerbating existing inequity by placing further burdens on communities that are already vulnerable. Risk exposure varies by where people live and work. In this article, we examine the spatial overlap of the compound risks of COVID-19 and extreme heat in New York City. We assess the relationship between socio-demographic and natural, built and social environmental characteristics, and the spatial correspondence of COVID-19 daily case rates across three pandemic waves. We use these data to create a compound risk index combining heat, COVID-19, density and social vulnerability. Our findings demonstrate …

Logic And Rationality, Rohit J. Parikh

Publications and Research

Logic aims at truth, or more accurately, at deriving some truths from other truths. But why are we interested in truth in the first place? Surely one reason is that relying on truth makes it easier to make better choices.

One could think of Game theory as a tool which bridges the gap between logic and rationality.

Decision theory - or single agent game theory tells us when to make the best choice in a game of us against nature. But nature has no desire to further or frustrate our efforts. Nature is mysterious but not malign. Things change when …

To Ask Or Not To Ask? Dynamic Systems Perspective On Help Seeking In An Introductory Statistics Classroom, Bradley W. Bergey

Publications and Research

Student-generated questions are an important mechanism for learning and self-regulation, yet their scarcity in classroom discourse points to a need to understand how students decide to ask or withhold their questions. This study examined how 12 graduate students in an introductory statistics course made decisions about asking questions during whole group instruction. Help seeking decisions were framed as arising from a dynamic system of a student’s situated role identity as a class participant. Qualitative analysis of post-class interviews illustrated the highly contextual, dynamic nature of students’ decisions to ask or withhold questions. Analyses revealed an array of microdecisions that involved …

How Do Classroom-Turnover Times Depend On Lecture-Hall Size?, Joseph Benson, Mariya Bessonov, Korana Burke, Simone Cassani, Maria-Veronica Ciocanel, Daniel B. Cooney, Alexandria Volkening

Publications and Research

Academic spaces in colleges and universities span classrooms for 10 students to lecture halls that hold over 600 people. During the break between consecutive classes, students from the first class must leave and the new class must find their desks, regardless of whether the room holds 10 or 600 people. Here we address the question of how the size of large lecture halls affects classroom-turnover times, focusing on non-emergency settings. By adapting the established social-force model, we treat students as individuals who interact and move through classrooms to reach their destinations. We find that social interactions and the separation time …

Orbital Decay In The Classroom, Miguel C. N. Fiolhais, Luis Gonzalez-Urbina, Tomasz Milewski, Carlos Chaparro, Andrea Ferroglia

Publications and Research

The objective of this paper is to provide a pedagogical framework for the phenomenon of orbital decay of satellites in low Earth orbit. The dynamics of orbital decay are derived considering atmospheric drag as the only dissipative mechanism and using an educational approach suitable for undergraduate calculus-based physics and engineering courses. The resulting nonlinear first-order differential equation for the altitude as a function of time is solved numerically for the isothermal-barotropic atmospheric model with a fixed scale height. The model is validated using the uncontrolled reentry data of the Chinese space station Tiangong-1.

The “Heaven Ab Initio” Argument From Evil, Carlo Alvaro

Publications and Research

Logical and evidential arguments from evil are generally thought to have been rebutted by various refutations, defenses, and theodicies. While disparate, these responses employ similar strategies to show that God has morally sufficient reasons to permit evil and suffering in the world, either to preserve human freedom, for the sake of the moral growth of human souls, or to train humans to be able to act freely without sinning once in heaven. In this paper, I defend the heaven ab initio argument from evil (HAIAFE), which demonstrates that God could have accomplished all these goals, without the need for evil …

Muon-Electron Scattering At Nnlo, A. Broggio, T. Engel, Andrea Ferroglia, M. K. Mandal, P. Mastrolia, M. Rocco, J. Ronca, A. Signer, W. J. Torres Bobadilla, Y. Ulrich, M. Zoller

Publications and Research

We present the first calculation of the complete set of NNLO QED corrections for muon-electron scattering. This includes leptonic, non-perturbative hadronic, and photonic contributions. All fermionic corrections as well as the photonic subset that only corrects the electron or the muon line are included with full mass dependence. The genuine four-point two-loop topologies are computed as an expansion in the small electron mass, taking into account both, logarithmically enhanced as well as constant mass effects using massification. A fast and stable implementation of the numerically delicate real-virtual contribution is achieved by combining OPENLOOPS with next-to-soft stabilisation. All matrix elements are …

Incision Precision: Engaging Students During Dissection Labs, Azure N. Faucette

Publications and Research

Active learning tools, such as gamification, have facilitated teamwork and improved decision-making skills in Anatomy and Physiology classes. However, most Anatomy and Physiology labs currently contain dissection activities where students are not likely to engage in inquiry, critical thinking, or problem-solving. Usually, the instructor gives a brief lecture on the topic, and students are left to dissect without understanding how the lecture relates to what is in front of them, which is frustrating. Coupled with the frustration, some students have adverse opinions on dissecting specimens, including hesitation to dissect the specimen and religious or ethical concerns with dissection. Utilizing similar …

Unpacking Chemistry Teachers’ Pedagogical Reasoning And Decisions For A Phet Simulation: A Tpack Perspective, Xiaoyang Gong, Bing Wei, Bradley W. Bergey, Ebony Terrell Shockley

Publications and Research

Computer simulations hold great potential for enhancing chemistry instruction. However, effectively integrating simulations in instruction depends in part on teachers’ pedagogical reasoning about simulation affordances and instructional decisions within specific classroom contexts. The objective of this study was to investigate how two chemistry teachers evaluated an interactive simulation and determined pedagogical strategies for integrating the simulation into classroom instruction. Based on the TPACK framework, authors adopted a comparative case study approach to interpret qualitative data from three sources: screen-capture videos, interviews, and instructional plans. Results showed that pedagogical reasoning and decisions of the two participants reflected different TPACK components. One …

It Turned Into A Bioblitz: Urban Data Collection For Building Scientific Literacy And Environmental Connection, Kelly O'Donnell, Lisa Brundage

Publications and Research

In 2013, Macaulay Honors College redesigned its required science curriculum to focus on scientific literacy skills rather than content. Central to this shift was inclusion of a data collection event, a BioBlitz, to provide students with the basis for their own semester-long research projects. Students are teamed with naturalists in an urban green space to find as many species as they can in 24 h and to contribute to a global biodiversity database via the app iNaturalist. We have learned two important lessons: (1) developing an interdisciplinary curriculum with a high degree of experiential learning is more successful when both …

Indigenous And Western Sciences In Carlos Hernandez's The Assimilated Cuban's Guide To Quantum Santeria, Joy Sanchez-Taylor

Publications and Research

This chapter examines Carlos Hernandez’s The Assimilated Cuban’s Guide to Quantum Santeria as an example of how authors of alternative futurisms can draw on Indigenous knowledge to destabilize Eurowestern perceptions that Western science is more modern and rational than Indigenous knowledge. Joy Sanchez-Taylor argues that Hernandez combines references to Santería and quantum physics to demonstrate parallels between Indigenous knowledge and Eurowestern “rational” science. Ultimately, references in Quantum Santeria to ideas of spiritual healing and nonlinear time demonstrate how authors like Hernandez are working to restore Biskaabiiyang, or a return to self, within science fiction.

R-Symmetries And Curvature Constraints In A-Twisted Heterotic Landau–Ginzburg Models, Richard S. Garavuso

Publications and Research

In this paper, we discuss various aspects of a class of A-twisted heterotic Landau–Ginzburg models on a Kähler variety X. We provide a classification of the R-symmetries in these models which allow the A-twist to be implemented, focusing on the case in which the gauge bundle is either a deformation of the tangent bundle of X or a deformation of a sub-bundle of the tangent bundle of X. Some anomaly-free examples are provided. The curvature constraint imposed by supersymmetry in these models when the superpotential is not holomorphic is reviewed. Constraints of this nature have been used to establish properties …

Futures On Dry Ground: Anthropology And Coastal Planning, Theodore Hilton, Sheehan Moore

Publications and Research

Around the world, governments, industry, and other actors are creating plans to save coasts from environmental crisis. Louisiana is one prominent example: levees and other measures protect oil and gas infrastructure from inundation as the wetlands buffer rapidly erodes—in large part due to that same industry. The state’s primary answer to land loss is a $50 billion Coastal Master Plan. To illuminate such responses in Louisiana and globally, this article reviews emerging literature and frames an anthropology of coastal planning around three themes: (1) novel orientations toward time and space, (2) the reproduction of power and capital in the name …

Beyond Demographic Identifiers And Classification: A Search For Alternative Approaches To Quantitatively Evaluating Educational Equity, Grace Pai

Publications and Research

In April 2022, United States Agency for International Development (USAID) released its first ever Equity Action Plan to advance equity across their policies, programs, and partner base. This action plan entails five priority areas, the fifth of which is to: “…incorporate racial and ethnic equity and diversity into policy, planning, and learning” (USAID, 2022, para. 3). This essay addresses the question of how USAID, along with other international development agencies and practitioners, can institutionalize equity, particularly in its evaluation and data collection processes. I argue that as interest in addressing diversity, equity, and inclusion (DEI)1 increases in the U.S. and …
