Eukaryotic Initiation Factor 4f Promotes A Reorientation Of Eukaryotic Initiation Factor 3 Binding On The 5 And The 3 Utrs Of Barley Yellow Dwarf Virus Mrna, Paul Powell, Usha Bhardwaj, Dixie Goss

Publications and Research

Viral mRNAs that lack a 5 m 7 GTP cap and a 3 poly-A tail rely on structural elements in their untranslated regions (UTRs) to form unique RNA-protein complexes that regulate viral translation. Recent studies of the barley yellow dwarf virus (BYDV) have revealed eukaryotic initiation factor 3 (eIF3) plays a significant role in facilitating communication be- tween its 5 and 3 UTRs by binding both UTRs simultaneously. This report uses in vitro translation assays, fluorescence anisotropy binding assays, and selective 2 -hydroxyl acylation analyzed by primer ex-tension (SHAPE) footprinting to identify secondary structures that are selectively interacting with eIF3. …

Adapting Human-Based Transcutaneous Spinal Cord Stimulation To Develop A Clinically Relevant Animal Model, Dillon C. Malloy, Maria Knikou, Marie-Pascale Côté

Publications and Research

Transcutaneous spinal cord stimulation (tSCS) as a neuromodulatory strategy has received great attention as a method to promote functional recovery after spinal cord injury (SCI). However, due to the noninvasive nature of tSCS, investigations have primarily focused on human applications. This leaves a critical need for the development of a suitable animal model to further our understanding of this therapeutic intervention in terms of functional and neuroanatomical plasticity and to optimize stimulation protocols. The objective of this study is to establish a new animal model of thoracolumbar tSCS that (1) can accurately recapitulate studies in healthy humans and (2) can …

Ungrading In Art History: Grade Inflation, Student Engagement, And Social Equity, Lauren Disalvo, Nancy Ross

Art History Pedagogy & Practice

Traditional academic pedagogies require that professors assign students grades in a system that creates hierarchies of power of professor over student. This system assumes that grades serve as an intrinsic motivator for students to improve in an academic setting. Many studies suggest that professor-assigned grades do not function as assumed. This article explores one alternative to the traditional system, known as ungrading, a practice whereby students assign themselves grades after a semester of frequent feedback and reflective assignments. This study offers a thematic literature review of ungrading in many disciplines and a small study of ungrading in upper-division art history …

Cosmogenic Ages Indicate No Mis 2 Refugia In The Alexander Archipelago, Alaska, Caleb K. Walcott, Jason P. Briner, James F. Baichtal, Alia J. Lesnek, Joseph M. Licciardi

Publications and Research

The late-Pleistocene history of the coastal Cordilleran Ice Sheet remains relatively unstudied compared to chronologies of the Laurentide Ice Sheet. Yet accurate reconstructions of Cordilleran Ice Sheet extent and the timing of ice retreat along the Pacific Coast are essential for paleoclimate modeling, assessing meltwater contribution to the North Pacific, and determining the availability of ice-free land along the coastal Cordilleran Ice Sheet margin for human migration from Beringia into the rest of the Americas. To improve the chronology of Cordilleran Ice Sheet history in the Alexander Archipelago, Alaska, we applied 10Be and 36Cl dating to boulders and glacially sculpted …

Stigma Towards Offenders Diagnosed With Mental Illness, Christina N. Yocca

Student Theses

Mental health stigma is a key factor to what makes members of the community who are diagnosed with mental illness feel like outcasts to the “normal” population. This study investigated the relationship between right-winged beliefs and offenders diagnosed with mental illness. Sigma as it relates to mental health, offenders, and right-winged beliefs have been studied separately before, but there is a lack of information on the stigma that the public has towards offenders who struggle with their mental health and the possible predictors of stigma towards this group. Overall, this study aimed to further research in the intersectionality of stigmatized …

The Contemporary American Juvenile Justice System: Revisiting Parens Patriae, Katarzyna Celinska, Amina Cheboubi

Publications and Research

The American juvenile justice system has undergone significant transformations since its inception in the late 19th century. In this paper, the authors seek to analyze the historical context of and subsequent reforms to the juvenile system and process in order to determine whether they remain true to their origins of the legal doctrine of parens patriae. Specifically, the authors contrast rehabilitative notions of parens patriae with the “tough on crime” perspective that developed in the 1990s in response to rising crime rates. This debate is illustrated by landmark Supreme Court cases, waivers to the adult system, increases in the use …

“I Can Math, Too!”: Reducing Math Anxiety In Stem-Related Courses Using A Combined Mindfulness And Growth Mindset Approach (Magma) In The Classroom, Tashana S. Samuel, Sebastien Buttet, Jared Warner

Publications and Research

Math anxiety has become an alarming social justice concern, as it results in negative academic consequences, contributes to disinterest and lack of persistence in STEM programs for underrepresented students, and limits their opportunities in STEM careers. According to research, this fear of math occurs long before students begin working on math problems. When high-math anxious students encounter math situations, anticipation anxiety consumes working memory capacity, inhibits learning, and causes them to severely underperform on mathematical tasks. However, very few studies have been conducted to embed psychological interventions in the classroom in an effort to mitigate both anticipation and execution anxiety. …

Prmt5 Interacting Partners And Substrates In Oligodendrocyte Lineage Cells, David K. Dansu, Jialiang Liang, Ipek Selcen, Haiyan Zheng, Dirk F. Moore, Patricia Casaccia

Advanced Science Research Center

The protein arginine methyl transferase PRMT5 is an enzyme expressed in oligodendrocyte lineage cells and responsible for the symmetric methylation of arginine residues on histone tails. Previous work from our laboratory identified PRMT5 as critical for myelination, due to its transcriptional regulation of genes involved in survival and early stages of differentiation. However, besides its nuclear localization, PRMT5 is found at high levels in the cytoplasm of several cell types, including oligodendrocyte progenitor cells (OPCs) and yet, its interacting partners in this lineage, remain elusive. By using mass spectrometry on protein eluates from extracts generated from primary oligodendrocyte lineage cells …

Advanced Science Research Center

A library of thio- and selenourea derivatives is used to adjust the kinetics of PbE (E = S, Se) nanocrystal formation across a 1000-fold range (kr = 10−1 to 10−4 s−1), at several temperatures (80–120 °C), under a standard set of conditions (Pb : E = 1.2 : 1, [Pb(oleate)2] = 10.8 mM, [chalcogenourea] = 9.0 mM). An induction delay (tind) is observed prior to the onset of nanocrystal absorption during which PbE solute is observed using in situ X-ray total scattering. Density functional theory models fit to the X-ray pair distribution function (PDF) support a Pb2(μ2-S)2(Pb(O2CR)2)2 structure. Absorption spectra …

Spin-Orbit Gravitational Locking - An Effective Potential Approach, Christopher Clouse, Andrea Ferroglia, Miguel C. N. Fiolhais

Publications and Research

The objective of this paper is to study the tidally locked 3:2 spin–orbit resonance of Mercury around the Sun. In order to achieve this goal, the effective potential energy that determines the spinning motion of an ellipsoidal planet around its axis is considered. By studying the rotational potential energy of an ellipsoidal planet orbiting a spherical star on an elliptic orbit with fixed eccentricity and semi-major axis, it is shown that the system presents an infinite number of metastable equilibrium configurations. These states correspond to local minima of the rotational potential energy averaged over an orbit, where the ratio between …

Visual Diaries: Towards Art History As Storytelling, Alpesh Kantilal Patel

Art History Pedagogy & Practice

This essay examines variants of what I refer to as “visual diaries” – or thinking through images and written or oral language – as important “worldmaking” exercises, essential for students of color, women, sexual minorities, or other marginalized subjects. I provide my reflections on assigning this dynamic and student-centered, practice-based assignment in my contemporary art courses at a Hispanic-serving institution (HSI) of higher education and a summer art residency program unaffiliated with a university. Besides my reflections on my pedagogy, I also share student feedback from unsolicited testimonials and answers to questionnaires. I argue that visual diaries transform students into …

Library Wayfinding And Esol Students: Communication Challenges And Empathy-Based Intervention, Nora Almeida, Junior R. Tidal

Publications and Research

This article describes a wayfinding study conducted in an urban, academic library to better understand the experiences of multilingual student populations. The study, which incorporated traditional user experience methods and video ethnography, exposed communication obstacles and spatial challenges encountered by students of English for speakers of other languages (ESOL) when attempting information retrieval tasks. After outlining the methodology and examining qualitative findings, the authors discuss how study findings prompted a reevaluation of local practices, service models, and staff training protocols. Finally, the authors explore the potential for qualitative, empathy-based wayfinding studies to transform library practices and spaces.

Hyperbolic Shear Polaritons In Low-Symmetry Crystals, Nikolai C. Passler, Xiang Ni, Guangwei Hu, Joseph R. Matson, Giulia Carini, Martin Wolf, Mathias Schubert, Andrea Alù, Joshua D. Caldwell, Thomas G. Folland, Alexander Paarmann

Advanced Science Research Center

The lattice symmetry of a crystal is one of the most important factors in determining its physical properties. Particularly, low-symmetry crystals offer powerful opportunities to control light propagation, polarization and phase. Materials featuring extreme optical anisotropy can support a hyperbolic response, enabling coupled light–matter interactions, also known as polaritons, with highly directional propagation and compression of light to deeply sub-wavelength scales. Here we show that monoclinic crystals can support hyperbolic shear polaritons, a new polariton class arising in the mid-infrared to far-infrared due to shear phenomena in the dielectric response. This feature emerges in materials in which the dielectric tensor …

Designing Respectful Tech: What Is Your Relationship With Technology?, Noreen Y. Whysel

Publications and Research

According to research at the Me2B Alliance, people feel they have a relationship with technology. It’s emotional. It’s embodied. And it’s very personal. We are studying digital relationships to answer questions like “Do people have a relationship with technology?” “What does that relationship feel like?” And “Do people understand the commitments that they are making when they explore, enter into and dissolve these relationships?” There are parallels between messy human relationships and the kinds of relationships that people develop with technology. As with human relationships, we move through states of discovery, commitment and breakup with digital applications as well. Technology …

To identify determinants of daily life stress in Africans in America, 156 African-born Blacks (Age: 40 ± 10 years (mean ± SD), range 22-65 years) who came to the United States as adults (age ≥ 18 years) were asked about stress, sleep, behavior and socioeconomic status. Daily life stress and sleep quality were assessed with the Perceived Stress Scale (PSS) and Pittsburgh Sleep Quality Index (PSQI), respectively. High-stress was defined by the threshold of the upper quartile of population distribution of PSS (≥16) and low-stress as PSS < 16. Poor sleep quality required PSQI > 5. Low income was defined as groups, PSS were: 21 ± 4 versus …

Spatial Downscaling Of Goes-R Land Surface Temperature Over Urban Regions: A Case Study For New York City, Abdou Bah, Hamidreza Norouzi, Satya Prakash, Reginald Blake, Reza Khanbilvardi, Cynthia Rosenzweig

Publications and Research

The surface urban heat island (SUHI) effect is among the major environmental issues encountered in urban regions. To better predict the dynamics of the SUHI and its impacts on extreme heat events, an accurate characterization of the surface energy balance in urban regions is needed. However, the ability to improve understanding of the surface energy balance is limited by the heterogeneity of surfaces in urban areas. This study aims to enhance the understanding of the urban surface energy budget through an innovation in the use of land surface temperature (LST) observations from remote sensing satellites. A LST database with 5–min …

Spontaneous Eye Blink Rate During The Working Memory Delay Period Predicts Task Accuracy, Jefferson Ortega, Chelsea Reichert Plaska, Bernard Gomes, Timothy M. Ellmore

Publications and Research

Spontaneous eye blink rate (sEBR) has been linked to attention and memory, specifically working memory (WM). sEBR is also related to striatal dopamine (DA) activity with schizophrenia and Parkinson’s disease showing increases and decreases, respectively, in sEBR. A weakness of past studies of sEBR and WM is that correlations have been reported using blink rates taken at baseline either before or after performance of the tasks used to assess WM. The goal of the present study was to understand how fluctuations in sEBR during different phases of a visual WM task predict task accuracy. In two experiments, with recordings of …

A Novel Non‑Selective Atypical Pkc Agonist Could Protect Neuronal Cell Line From A Β ‑Oligomer Induced Toxicity By Suppressing A Β Generation, Dongmei Zou, Qian Li, Wenyang Pan, Peng Chen, Miao Sun, Xiaofeng Bao

Publications and Research

Atypical protein kinase C (aPKCs) serve key functions in embryonic development by regulating apical-basal polarity. Previous studies have shed light on their roles during adulthood, especially in the development of Alzheimer's disease (AD). Although the crystal structure of PKCι has been resolved, an agonist of aPKCs remains to be discovered. In the present study, by using the Discovery Studio program and LibDock methodology, a small molecule library (K66-X4436 KINA Set) of compounds were screened for potential binding to PKCι. Subsequently, the computational docking results were validated using affinity selection-mass spectrometry, before in vitro kinase activity was used to determine the …

Ontogenetic Drivers Of Morphological Evolution In Monitor Lizards And Allies (Squamata: Paleoanguimorpha), A Clade With Extreme Body Size Disparity, Carlos J. Pavón-Vázquez, Damien Esquerré, J. Scott Keogh

Publications and Research

Background

Heterochrony, change in the rate or timing of development, is thought to be one of the main drivers of morphological evolution, and allometry, trait scaling patterns imposed by size, is traditionally thought to represent an evolutionary constraint. However, recent studies suggest that the ontogenetic allometric trajectories describing how organisms change as they grow may be labile and adaptive. Here we investigated the role of postnatal ontogenetic development in the morphological diversification of Paleoanguimorpha, the monitor lizards and allies, a clade with extreme body size disparity. We obtained linear and geometric morphometric data for more than 1,600 specimens belonging to …
