Artificial Intelligence And The Situational Rationality Of Diagnosis: Human Problem-Solving And The Artifacts Of Health And Medicine, Michael W. Raphael

Publications and Research

What is the problem-solving capacity of artificial intelligence (AI) for health and medicine? This paper draws out the cognitive sociological context of diagnostic problem-solving for medical sociology regarding the limits of automation for decision-based medical tasks. Specifically, it presents a practical way of evaluating the artificiality of symptoms and signs in medical encounters, with an emphasis on the visualization of the problem-solving process in doctor-patient relationships. In doing so, the paper details the logical differences underlying diagnostic task performance between man and machine problem-solving: its principle of rationality, the priorities of its means of adaptation to abstraction, and the effects …

New Approaches To Peer Leader Training, Nadia Kennedy

Publications and Research

This paper describes a Peer Leader training course that has been modified to include innovative components focusing on developing content and pedagogical knowledge, practicing rehearsals, generating action research projects, doing poster presentations, and writing a reflective letter to new Peer Leaders. Through these innovations, four types of reflection–on relevant research and theory, on students’ experiences, on peer practice, and on one’s own practice–have been incorporated into the course. The new course components promise to offer more opportunities for trainees to practice peer leading in a structured and safe environment in which immediate and supportive feedback is available, and group practice …

Conflict Dynamics In Scale-Free Networks With Degree Correlations And Hierarchical Structure, Eduardo Jacobo-Villegas, Bibiana Obregón-Quintana, Lev Guzmán-Vargas, Larry S. Liebovitch

Publications and Research

We present a study of the dynamic interactions between actors located on complex networks with scale-free and hierarchical scale-free topologies with assortative mixing, that is, correlations between the degree distributions of the actors. The actor’s state evolves according to a model that considers its previous state, the inertia to change, and the influence of its neighborhood. We show that the time evolution of the system depends on the percentage of cooperative or competitive
interactions. For scale-free networks, we find that the dispersion between actors is higher when all interactions are either cooperative or competitive, while a balanced presence of interactions …

Sustainability Matters: Advocating For The Establishment And Continuation Of Peer-Led Team Learning, A.E. Dreyfuss

Publications and Research

The successful dissemination of the Peer-Led Team Learning (PLTL) model at multiple institutions of higher education, in the United States and other countries, is reflected in the number of publications (see www.pltlis.org). However, many PLTL campus programs are no longer active or exist. This may be due, more recently, to the COVID pandemic and its disruptions. Historically, programs no longer exist because grant funding that supported the initiative ended; other reasons include the promotion, retirement, or even death of the practitioners whose work championing their PLTL program ended. What can sustain a campus PLTL program so that its benefits …

Understanding The Vulnerability Of Staten Island's Eastern Coastline From A Beach Morphology Perspective, Jane L. Alexander, Amaury Acevedo, Jacklyn Reiszel

Publications and Research

Staten Island’s beaches were shown to be vulnerable to storm surge during Hurricane Sandy, with severe inundation into neighborhoods along the eastern shoreline; the area chosen for this study, and the area in which the Army Corps of Engineers plan to start constructing a seawall. A preliminary survey in summer 2018 suggested that this shoreline is reflective - i.e., one that changes little over the course of a year, but which is vulnerable to erosion during major storm events. The current work is designed to test the hypothesis that this is a reflective shoreline by completing regular field surveys over …

Microstructural Origin Of The High-Energy Storage Performance In Epitaxial Lead-Free Ba(Zr 0.2 Ti 0.8 )O 3 Thick Films, Jun Ouyang, Xianke Wang, Changtao Shao, Hongbo Cheng, Hanfei Zhu, Yuhang Ren

Publications and Research

In our previous work, epitaxial Ba(Zr 0.2 Ti 0.8 )O 3 thick films (~1–2 μ m) showed an excellent energy storage performance with a large recyclable energy density (~58 J/cc) and a high energy efficiency (~92%), which was attributed to a nanoscale entangled heterophase polydomain structure. Here, we propose a detailed analysis of the structure–property relationship in these film materials, using an annealing process to illustrate the effect of nanodomain entanglement on the energy storage performance. It is revealed that an annealing-induced stress relaxation led to the segregation of the nanodomains (via detailed XRD analyses), and a degraded energy storage …

Small Molecule Modulation Of Microbiota: A Systems Pharmacology Perspective, Qiao Liu, Bohyun Lee, Lei Xie

Publications and Research

Background

Microbes are associated with many human diseases and influence drug efficacy. Small-molecule drugs may revolutionize biomedicine by fine-tuning the microbiota on the basis of individual patient microbiome signatures. However, emerging endeavors in small-molecule microbiome drug discovery continue to follow a conventional “one-drug-one-target-one-disease” process. A systematic pharmacology approach that would suppress multiple interacting pathogenic species in the microbiome, could offer an attractive alternative solution.

Results

We construct a disease-centric signed microbe–microbe interaction network using curated microbe metabolite information and their effects on host. We develop a Signed Random Walk with Restart algorithm for the accurate prediction of effect of microbes …

Elementary Students' Engineering Design Process: How Young Students Solve Engineering Problems, Euisuk Sung, Todd R. Kelley

Publications and Research

With the increasing importance of teaching STEM to young students, the engineering design process (EDP) has become a popular learning platform in K-12 STEM education. The engineering design process guides students in solving engineering problems, but there is a lack of understanding of how students utilize this process. In this study, we explored how iterative design activities form procedural patterns of the engineering design process using sequential analysis. We videotaped 48 engineering design sessions via the Concurrent Think-Aloud (CTA) protocol from elementary students grades 3–6 in the USA. The data was coded using Halfn’s codes. The sequential analyses identified the …

This paper describes the Gender Equity Project (GEP) at Hunter College of the City University of New York (CUNY), funded by the U. S. NSF ADVANCE Institutional Transformation Award (ITA) program. ADVANCE supports system-level strategies to promote gender equity in the social and natural sciences, but has supported very few teaching-intensive institutions. Hunter College is a teaching-intensive institution in which research productivity among faculty is highly valued and counts toward tenure and promotion. We created the GEP to address the particular challenges that faculty, especially White women and faculty of color, face in maintaining research programs and advancing in their …

Toward Informatics-Enabled Preparedness For Natural Hazards To Minimize Health Impacts Of Climate Change, Jimmy Phuong, Naomi O. Riches, Luca Calzoni, Gora Datta, Deborah Duran, Asiyah Yu Lin, Ramesh P. Singh, Anthony E. Solomonides, Noreen Y. Whysel, Ramakanth Kavuluru

Publications and Research

Natural hazards (NHs) associated with climate change have been increasing in frequency and intensity. These acute events impact humans both directly and through their effects on social and environmental determinants of health. Rather than relying on a fully reactive incident response disposition, it is crucial to ramp up preparedness initiatives for worsening case scenarios. In this perspective, we review the landscape of NH effects for human health and explore the potential of health informatics to address associated challenges, specifically from a preparedness angle. We outline important components in a health informatics agenda for hazard preparedness involving hazard-disease associations, social determinants …

Phylogenetic Diversity Of Animal Oral And Gastrointestinal Viromes Useful In Surveillance Of Zoonoses, Anthony Michael Esposito, Michelle Marie Esposito, Albert Ptashnik

Publications and Research

Great emphasis has been placed on bacterial microbiomes in human and animal systems. In recent years, advances in metagenomics have allowed for the detection and characterization of more and more native viral particles also residing in these organisms. The digestive tracts of animals and humans—from the oral cavity, to the gut, to fecal excretions—have become one such area of interest. Next-generation sequencing and bioinformatic analyses have uncovered vast phylogenetic virome diversity in companion animals, such as dogs and cats, as well as farm animals and wildlife such as bats. Zoonotic and arthropod-borne illnesses remain major causes of worldwide outbreaks, as …

The Wisdom In Our Stories: Asian American Motherscholar Voices, Cathery Yeh, Ruchi Agarwal-Rangnath, Betina Hsieh, Judy Yu

Publications and Research

This article centers the counternarratives of four Asian American motherscholar teacher educators presented as letters to our children in which we apply tenets of AsianCrit to parenting and education, with racial realism at the forefront. Using Asian Critical Theory and motherscholar research to frame our analysis, themes within and across the data include pressures of cultural assimilation and identity loss, intersectional identities, compliance and resistance to Asianization, and learning from our children. Our Asian American motherscholar stories serve as examples of motherhood as an asset to critical scholarship and praxis.

Generalization Of Bi-Canonical Degrees, Joseph Brennan, Laura Ghezzi, Jooyoun Hong, Wolmer Vasconcelos

Publications and Research

We discuss invariants of Cohen-Macaulay local rings that admit a canonical module ω. Attached to each such ring R, when ω is an ideal, there are integers–the type of R, the reduction number of ω–that provide valuable metrics to express the deviation of R from being a Gorenstein ring. In (Ghezzi et al. in JMS 589:506–528, 2017) and (Ghezzi et al. in JMS 571:55–74, 2021) we enlarged this list with the canonical degree and the bi-canonical degree. In this work we extend the bi-canonical degree to rings where ω is not necessarily an ideal. We also discuss generalizations to rings …

How Many Mutex Bugs Can A Simple Analysis Find In Go Programs?, Fumi Takeuchi, Hidehiko Masuhara, Raffi Khatchadourian, Youyou Cong, Keisuke Ishibashi

Publications and Research

In open-source software, it is known that there are many concurrency bugs. A previous study in Go revealed that a considerable number of such bugs are simple (for example, 9% of the bugs are the ones that forget to unlock a mutex,) through a manual program investigation. This paper tries to detect such bugs by applying a simple analysis to see how far such a tool can match the manual analysis. We built a simple intraprocedural control flow analysis in Go, and evaluated its performance concerning the open source programs with concurrency bugs reported in the previous study. Consequently, as …

Building Capacity: Enhancing Undergraduate Stem Education By Improving Transfer Success, Pamela Brown

Publications and Research

Several evidence-based practices were combined to reduce barriers to transfer from associate to baccalaureate programs, and baccalaureate degree completion. The first strategy was creation of the STEM Transfer Collaborative (STC), an adaption of the CUNY Pathways general education articulation initiative (1). The STC focuses on collaboration by both the sending and receiving college faculty to begin transfer preparation and support before transfer occurs, through articulation agreements, shared professional development to align pedagogy and curriculum, and outreach to potential transfer students. There was also regular feedback to community college faculty on the success of their transfer students. A second strategy employed …

Rna-As-Graphs Motif Atlas—Dual Graph Library Of Rna Modules And Viral Frameshifting-Element Applications, Qiyao Zhu, Louis Petingi, Tamar Schlick

Publications and Research

RNA motif classification is important for understanding structure/function connections and building phylogenetic relationships. Using our coarse-grained RNA-As-Graphs (RAG) representations, we identify recurrent dual graph motifs in experimentally solved RNA structures based on an improved search algorithm that finds and ranks independent RNA substructures. Our expanded list of 183 existing dual graph motifs reveals five common motifs found in transfer RNA, riboswitch, and ribosomal 5S RNA components. Moreover, we identify three motifs for available viral frameshifting RNA elements, suggesting a correlation between viral structural complexity and frameshifting efficiency. We further partition the RNA substructures into 1844 distinct submotifs, with pseudoknots and …

The 'Quantal Newtonian' First Law: A Complementary Perspective To The Stationary-State Quantum Theory Of Electrons, Viraht Sahni

Publications and Research

A complementary perspective to the Göttingen-Copenhagen interpretation of stationary-state quantum theory of electrons in an electromagnetic field is described. The perspective, derived from Schrödinger-Pauli theory, is that of the individual electron via its equation of motion or ‘Quantal Newtonian’ First Law. The Law is in terms of ‘classical’ fields experienced by each electron: the sum of the external and internal fields vanishes. The external field is a sum of the electrostatic and Lorentz fields. The internal field is a sum of fields’ representative of Pauli and Coulomb correlations; kinetic effects; electron density; and internal magnetic component. The energy is obtained …

Arrayed Waveguide Lens For Beam Steering, Mostafa Honari-Latifpour, Ali Binaie, Mohammad Amin Eftekhar, Nicholas Madamopoulos, Mohammad-Ali Miri

Publications and Research

Integrated planar lenses are critical components for analog optical information processing that enable a wide range of applications including beam steering. Conventional planar lenses require gradient index control which makes their on-chip realization challenging. Here, we introduce a new approach for beam steering by designing an array of coupled waveguides with segmented tails that allow for simultaneously achieving planar lensing and off-chip radiation. The proposed arrayed waveguide lens is built on engineering the evanescent coupling between adjacent channels to realize a photonic lattice with an equi-distant ladder of propagation constants that emulates the continuous parabolic index profile. Through coupled-mode analysis …

Using A Standards Crosswalk To Adapt Resources For Teaching With Primary Sources Across K–12 And Higher Education, Jen Hoyer

Publications and Research

This article explores the work of archivists and special collections librarians in teaching with primary sources (TPS) for K–12 and higher education audiences and argues that the resources created for this work have largely targeted either audience, but not both. Building on a trend in the TPS literature toward skills-based instruction efforts, this article introduces a crosswalk between skills-based standards typically used in higher education (the SAA/RBMS Guidelines for Primary Source Literacy) and K–12 education (Common Core State Standards). This crosswalk demonstrations how resources created with one audience in mind can be adapted for use with other audiences. Examples of …
