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 …

Pulling It All Together: Teaching Genre, Disciplinary And Career Literacies, And The Framework For Information Literacy In An Associate Degree Capstone Course, Linda Miles, Elisabeth Tappeiner

Art, Propaganda, And Truth, Melissa Dinsman

Publications and Research

This essay explores how British and American writers and theorists in the first half of the twentieth century thought about art, propaganda, and truth. Focusing largely on literature written during the First and the Second World Wars, this essay shows that very few authors defined their art as propaganda or truth and instead used words like “political,” “resistance,” “information,” and “anti-fascist” to describe their wartime writing. However, while authors might have eschewed the term propaganda, that does not mean that they avoided producing it. As this essay illustrates, what many authors wrote would now be considered “propaganda.” Moreover, even if …

Publications and Research

Studies on the efficacy of language treatment for multilingual people with post-stroke aphasia and its generalization to untreated languages have produced mixed results. We conducted a systematic review and a meta- analysis to examine within- and cross-language treatment effects and the variables that affect them. We searched PubMed, PsycINFO, CINAHL, and Google Scholar (February 2020; January 2023), identifying 40 studies reporting on 1573 effect sizes from 85 individuals. We synthesized effect sizes for treatment outcomes using a multi-level model to correct for multiple observations from the same individuals. The results showed significant treatment effects, with robust within-language treatment effects and …

Toward A New Approach To Job-Related Distress: A Three-Sample Study Of The Occupational Depression Inventory, Renzo Bianchi, James Sowden, Jay Verkuilen, Irvin Sam Schonfeld

Publications and Research

The Occupational Depression Inventory (ODI) was recently developed to assess depressive symptoms that individuals specifically attribute to their work. One purpose of the ODI is to respond to limitations of current assessments of job-related distress, most notably, assessments relying on the burnout construct. In this study, we conducted a thorough examination of the psychometric and structural properties of the ODI using exploratory structural equation modelling bifactor analysis and Mokken scale analysis. The study involved three samples of employed individuals, recruited in France (N = 3454), Switzerland (N = 1971), and Australia (N = 1485). Results were consistent across the three …

Taking Advantage Of Opportunities For Informal Leadership, Linda Miles, Susanne Markgren

Publications and Research

We contend that informal leadership (IL)—the type that does not come from an official title or decree—not only helps our organizations function, it can be vital in helping mid-career academic librarians grow and succeed, and such pursuits should be encouraged and supported no matter where they emerge within an organizational structure. We aim to define and explore IL and provide strategies for mid-career librarians who may want to identify, seek out, and step into IL opportunities. We begin our discussion by considering concepts emerging from the literature on leaders and leadership in general and what it means to lead when …

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 …

Publications and Research

Using data from a senior exit survey administered at public high schools in New York City, this study explores the relationship between quantity and quality of postsecondary advisement, parental/guardian involvement in postsecondary planning, and students’ likelihood of exiting high school with a full-time college plan. Results show receiving help in completing college applications, along with talking to a counselor and parents/guardians at least 3 times in their senior year, to be salient predictors of college-going.

Gender Differences In High School Students’ Perceived Values And Costs Of Learning Chemistry, Xiaoyang Gong, Bradley W. Bergey, Ying Jin, Kexin Mao, Yan Cheng

Publications and Research

Students’ perceived values and costs of learning chemistry influence their performance and intentions of choosing chemistry-related majors or careers. Based on Situated Expectancy-Value Theory, this study adopted a mixed method approach to examine the conceptualization of values and costs among Chinese high school students and identify their relations with chemistry test performance across gender. Qualitative content analyses revealed that students’ perceived values for chemistry could be categorized into five broad categories: utility value, epistemic value, intrinsic value, aesthetic value, and social value. Chi-square tests and multidimensional scaling revealed that boys and girls perceived values and costs in different ways: relational …

How A Community Engagement Model Of Near-Peer Counseling Impacts Student Mentors’ College Outcomes, Leigh Mccallen, Neshat Yazdani, Grace Pai, Janice Bloom, Lori Chajet, Michelle Fine

Publications and Research

This study examines how a community engagement model of near-peer counseling impacts counselors’ own college success as underrepresented students in higher education, here defined as one-year persistence in college. Near-peer mentors participated in a program provided by College Access: Research and Action (CARA), which trains young people to support peers in their home communities at New York City public high schools and City University of New York (CUNY) 2-year colleges through critical college application, enrollment, and retention milestones. Aggregated across 4 years of data, our results indicate CARA near-peer counselors are nearly twice as likely to persist in college (p < .001) as peers with similar demographic and academic characteristics not participating in CARA. Findings are replicated for students of color (2.09 times higher, p < .001) and economically disadvantaged students (1.78 times higher, p = .003). Implications for peer mentor program development through public university–community partnerships are discussed.

Misogynistic Extremism: A Scoping Review, Robin O'Hanlon, Frederick L. Altice, Roy Ka-Wei Lee, Jack Laviolette, Gloria Mark, Orestis Papakyriakopoulos, Koustuv Saha, Munmun De Choudhury, Navin Kumar

Publications and Research

In recent years, the concept of “misogynistic extremism” has emerged as a subject of interest among scholars, governments, law enforcement personnel, and the media. Yet a consistent understanding of how misogynistic extremism is defined and conceptualized has not yet emerged. Varying epistemological orientations may contribute to the current conceptual muddle of this topic, reflecting long-standing and on-going challenges with the conceptualization of its individual components. To address the potential impact of misogynistic extremism (i.e., violent attacks), a more precise understanding of what this phenomenon entails is needed. To summarize the existing knowledge base on the nature of misogynistic extremism, this …

The Routes Of Introspection, Adriana Renero

Publications and Research

In “What forms could introspective systems take? A research programme”, François Kammerer and Keith Frankish aim to map the space of “possible forms of introspection” while lending themselves to questions about how different kinds of minds represent themselves. This paper aligns with Kammerer and Frankish’s research programme in embracing other possible forms of introspection; it provides an outline of how, in representing its mental states, an introspective system could take a selective, cumulative, and/or predictive route while underscoring the importance of considering routes of introspection. Although this work only explores human minds, it contributes to Kammerer and Frankish’s research programme …

C-Glycopyranosyl Aldehydes: Emerging Chiral Synthons In Organic Synthesis, Sandeep Kumar, Vinod Khatri, Priyanka Mangla, Rajni Johar Chhatwal, Virinder S. Parmar, Ashok K. Prasad

Publications and Research

Herein, we have summarized the vast array of synthetic processes that have been developed for the synthesis of C-glycopyranosyl aldehydes and diverse C-glycoconjugates derived from them by covering the literature reported from 1979 to 2023. Notwithstanding its challenging chemistry, C-glycosides are considered stable pharmacophores and are used as important bioactive molecules. The discussed synthetic methodologies to access C-glycopyranosyl aldehydes take advantage of seven key intermediates, viz. allene, thiazole, dithiane, cyanide, alkene, and nitromethane. Furthermore, the integration of complex C-glycoconjugates derived from varied C-glycopyranosyl aldehydes involves nucleophilic addition/substitution, reduction, condensation, oxidation, cyclo condensation, coupling, and …

Distinctions Between Choroidal Neovascularization And Age Macular Degeneration In Ocular Disease Predictions Via Multi-Size Kernels Ξcho-Weighted Median Patterns, Alex Liew, Sos Agaian, Samir Benbelkacem

Publications and Research

Age-related macular degeneration is a visual disorder caused by abnormalities in a part of the eye’s retina and is a leading source of blindness. The correct detection, precise location, classification, and diagnosis of choroidal neovascularization (CNV) may be challenging if the lesion is small or if Optical Coherence Tomography (OCT) images are degraded by projection and motion. This paper aims to develop an automated quantification and classification system for CNV in neovascular age-related macular degeneration using OCT angiography images. OCT angiography is a non-invasive imaging tool that visualizes retinal and choroidal physiological and pathological vascularization. The presented system is based …

Logic As Applied Mathematics — With Particular Application To The Notion Of Logical Form, Graham Priest

Publications and Research

The word ‘logic’ has many senses. Here we will understand it as meaning an account of what follows from what and why. With contemporary methodology, logic in this sense – though it may not always have been thought of in this way – is a branch of applied mathematics. This has various implications for how one understands a number of issues concerning validity. In this paper I will explain this perspective of logic, and explore some of its consequences with respect to the notion of logical form.

Potential Anti-Alzheimer Properties Of Mogrosides In Vitamin B12-Deficient Caenorhabditis Elegans, Denia Cai Shi, Chunlin Long, Ella Vardeman, Edward J. Kennelly, Michael A. Lawton, Rong Di

Publications and Research

Vitamin B12 deficiency can lead to oxidative stress, which is known to be involved in neurodegenerative diseases such as Alzheimer’s disease (AD). Mogrosides are plant-derived triterpene glycosides that exhibit anti-inflammatory and antioxidant activity in animal cell lines and mouse models. Since amyloid-β toxicity is known to cause oxidative stress and damage to brain cells, we hypothesized that mogrosides may have a protective effect against AD. In this study, we investigated the potential anti-AD effect of mogrosides in vitamin B12-deficient wild-type N2 and in transgenic CL2355 Caenorhabditis elegans expressing amyloid-β peptide. Our data indicated that mogrosides have a beneficial effect on …

Quantity Of Questing Black-Legged Ticks And Associated Micro-Scale Environmental Data Collected From Four Suburban Parks Near New York City, Shipeng Sun, Chong Di, Li Li, Brian Sulkow, Weigang Qiu

Publications and Research

During 2017 and 2018, we collected the quantity of questing black-legged ticks (Ixodes scapularis), also known as deer ticks, in 124 sampling sites of 5m by 5m in four state parks—Caumsett State Historic Park, Connetquot River State Park, Rockefeller State Park, and Fire Island National Seashore—around New York City. The black-legged tick is the primary vector for the spirochete Borrelia burgdorferi, the pathogen of Lyme disease, in Northeastern United States. Using the flagging method, we collected and counted the numbers of adult and nymphal black-legged ticks at each site. Along with these quantities, we also recorded the …

Adaptive Single Low-Light Image Enhancement By Fractional Stretching In Logarithmic Domain, Thaweesak Trongtirakul, Sos S. Agaian, Shiqian Wu

Publications and Research

Low-light image enhancement is a challenging task that aims to improve the visibility and quality of images captured in dark environments. However, existing methods often introduce undesirable artifacts such as color distortion, halo effects, blocking artifacts, and noise amplification. In this paper, we propose a novel method that overcomes these limitations by using the logarithmic domain fractional stretching approach to estimate the reflectance component of the image based on the improved Retinex theory. Moreover, we apply a simple adaptive gamma correction algorithm to the Lab color-space to adjust the brightness and saturation of the image. Our method effectively reduces the …

Staging A Musical Self Through Paper, Canvas, And The Screen: A Taxonomy Of Musicians’ Self-Portraits From The Renaissance To The Digital Age, Antoni Pizà

Publications and Research

Abstract:

Musicians have engaged in visual self-representation at least since the Renaissance and have continued the tradition to modern times with contemporary practices including selfies and generative technology and AI art. The practitioners include so-called classical composers (Schoenberg is a well-known case) and performers (Caruso, for instance), but also pop singers and musicians (Joni Mitchell and Patti Smith, among others). The media used varies from oil on canvas to drawings on paper, from traditional photography to digital media. In some instances, there are grave, pompous self-representations, but caricatures also abound (e.g., Donizetti). There are also some miscategorized self-portraits (i.e., portraits …

Collecting And Curating Covid-19 Heritage: Challenges Of Conservation And Management, Kelly Britt

Publications and Research

The COVID-19 pandemic raises questions about curation, collecting, and the ethics of documenting a traumatic event as it occurs in real time. Such concerns became clear as the co-authors embarked on a multi-sited study of the pandemic’s impact on four communities in

two different countries. Defining an ‘artefact’ or what is archaeologi- cal, for instance, became a complicated exercise; do chalk artworks

on the sidewalk, painted rocks lining a neighbourhood trail, posters stapled on community billboards, and stuffed animals in someone’s window count as archaeological artefacts? Determining the temporal boundaries of the pandemic is also difficult; while it is fairly …

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 …

Differences Between Monolinguals And Bilinguals In Phonetic And Phonological Learning And The Connection With Auditory Sensory Memory, Laura Spinu, Jiwon Hwang, Mariana Vasilita

Publications and Research

Bilingualism has been linked with improved function regarding certain aspects of linguistic processing, e.g., novel word acquisition and learning unfamiliar sound patterns. Two non mutually-exclusive approaches might explain these results. One is related to executive function, speculating that more effective learning is achieved through actively choosing relevant information while inhibiting potentially interfering information. While still controversial, executive function enhancements attributed to bilingual experience have been reported for decades. The other approach, understudied to date, emphasizes the role of sensory mechanisms, specifically auditory sensory memory. Bilinguals outperformed monolinguals in tasks involving auditory processing and episodic memory recall, but the questions whether …
