Sensing Brownness: On Racialization, Perception, And Method, Amber Jamilla Musser

Publications and Research

Maureen Catbagan’s Dark Matter (2020) photography series invites us into sensing brownness. In these images of museum passages and stairwells, silhouettes of museum guards, and evocative shadows, Catbagan presents the landscape of the museum. However, this may not be immediately recognizable because the photographs draw focus to the parts of museums to which we rarely pay attention. In particular, Catbagan’s attention to the presence of guards allows us to perceive dynamics of racialized and gendered labor and laborers who, in an echo of their architectural focus on minor, peripheral spaces and shadows, hover between the underrecognized and oft-neglected, thereby allowing …

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 …

Sleep And Economic Status Are Linked To Daily Life Stress In African-Born Blacks Living In America., Zoe C. Waldman, Blayne R. Schenk, Marie Grace Duhuze Karera, Arielle C. Patterson, Thomas Hormenu, Lilian S. Mabundo, Christopher W. Dubose, Ram Jagannathan, Peter L. Whitesell, Annemarie Wentzel, Margrethe F. Horlyck-Romanovsky, Anne E. Sumner

Publications and Research

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 …

Pathological Human Tau Induces Alterations In The Brain Insulin Signaling Cascade, Abdeslem El Idrissi, Alejandra Del Carmen Alonso

Publications and Research

The process of neurodegeneration in Alzheimer’s disease has been associated with a disruption of insulin signaling cascade in neurons, and to insulin resistance. T2DM correlates with Alzheimer’s disease, but mechanisms of interaction are unknown. We have developed a mouse model of tau induced neurodegeneration expressing pseudo-phosphorylated tau [Pathological Human Tau (PH-Tau)] in neurons. This model (PH-Tau-Tg) recapitulated cognitive decline and neurodegeneration observed in AD. In this study we examined if expression of PH-Tau could affect neuronal excitability and insulin receptor signaling. Neuronal excitability was investigated using intracerebral recordings of extracellular field potentials from prefrontal cortex after insulin and kainic acid …

Integrating Natural Language Processing And Interpretive Thematic Analyses To Gain Human-Centered Design Insights On Hiv Mobile Health: Proof-Of-Concept Analysis, Simone J. Skeen, Stephen Scott Jones, Carolyn Marie Cruse, Keith J. Horvath

Publications and Research

Background: HIV mobile health (mHealth) interventions often incorporate interactive peer-to-peer features. The user-generated content (UGC) created by these features can offer valuable design insights by revealing what topics and life events are most salient for participants, which can serve as targets for subsequent interventions. However, unstructured, textual UGC can be difficult to analyze. Interpretive thematic analyses can preserve rich narratives and latent themes but are labor-intensive and therefore scale poorly. Natural language processing (NLP) methods scale more readily but often produce only coarse descriptive results. Recent calls to advance the field have emphasized the untapped potential of combined NLP …

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 …

Factors Associated With Hepatitis B Medication Adherence And Persistence Among Underserved Chinese And Vietnamese Americans, Aisha Bhimla, Lin Zhu, Wenyue Lu, Sarit Golub, Chibuzo Enemchukwu, Elizabeth Handorf, Yin Tan, Ming-Chin Yeh, Minhhuyen T. Nguyen, Min Qi Wang, Grace X. Ma

Publications and Research

Background: Hepatitis B virus (HBV) infection disproportionately affects Asian Amer- icans in the United States, while this population faces low adherence to HBV treatment. Using the information–motivation–behavioral skills model (IMB), the study aims to examine medication adherence and persistence among Chinese and Vietnamese people with HBV. Methodology: Study participants were recruited between March 2019 and March 2020 and were enrolled through multiple recruitment approaches in the Greater Philadelphia Area and New York City. The study is an assess- ment of the baseline data on medication adherence, HBV-related knowledge, motivation of HBV med- ication treatment, self-efficacy about HBV medication treatment, and …

Possibilities For Using Visual Drawing With Student-Teachers: Linking Childhood Memories To Future Teaching Selves, Debbie Sonu

Publications and Research

Drawing from memory-work, this study examines the relationship between childhood and the peda- gogical perspectives and practices of 16 pre-service student-teachers enrolled at one large university in the United States. In an analysis of their visual drawings and written narratives of childhood memories, student-teachers link childhood pasts with teaching futures in three distinct ways: 1) intimate con- nections with former teachers, 2) difficult life circumstances involving loss or trauma, and 3) the primacy of family and culture. Each set of memories is tied to a range of responsibilities that student-teachers vow to uphold, leading towards more re!exive practices in teacher …

Attitudes Towards Wearing Masks Among Young Adults, Diana Saiki, Alyssa Dana Adomaitis, Jay Kandiah

Publications and Research

The purpose of this study was to investigate attitudes about mask characteristics among young adults. Research questions included the following: (1) How do attitudes about: Do practical characteristics of masks influence mask-wearing? and (2) Does mask style and extrinsic characteristics influence mask-wearing? A mixed-methods approach was used. In December 2020, a survey was distributed online to fashion classes in the Midwest(rural) and Northeast (urban). The questionnaire contained a demographics section, open-ended questions about participants’ attitudes about masks, questions on mask-wearing behaviour, and a list of garment characteristics. The open-ended questions were analyzed for themes. The Likert scale questions were analyzed …

Linking Critical Consciousness And Health: The Utility Of The Critical Reflection About Social Determinants Of Health Scale (Cr_Sdh), Liliane Cambraia Windsor, Alexis Jemal, Jacob Goffnett, Douglas Cary Smith, Jesus Sarol Jr.

Publications and Research

Introduction: Critical consciousness (CC) theory has been proposed as a framework to inform health interventions targeting a wide variety of health conditions. Unfortunately, methodological limitations have made it difficult to test CC as a mediator of health outcomes. Specifically, standardized and widely accepted measures of health- related CC are needed. The goal of this study was to develop and test a measure of critical reflection on social determinants of health (SDH). This measure focused on critical reflection, an essential dimension of CC.

Methods: Community-based participatory research principles and a mixed methods design were used with three samples: (1) experts in …

Does Breastfeeding Account For The Association Between Maternal Sensitivity And Infant Cognitive Development In A Large, Nationally Representative Cohort?, P. Nina Banerjee, Karen E. Mcfadden, Jacqueline D. Shannon, Leslie L. Davidson

Publications and Research

Background: Previous research has established that exposure to high maternal sensitivity is positively associated with advances in infant cognitive development. However, there are many fixed and modifiable factors that influence this association. This study investigates whether the association between maternal sensitivity and infant cognitive development in the first year of life is accounted for by other factors, such as breastfeeding, maternal depressive symptoms, maternal alcohol use, infant birth weight or demographic covariates.

Methods: Using data from the Early Childhood Longitudinal Study-Birth (ECLS-B) Cohort, a nationally representative sample of U.S. born children, multi-variable regression analyses was used to examine whether breastfeeding, …

Emotion Recognition With Audio, Video, Eeg, And Emg: A Dataset And Baseline Approaches, Jin Chen, Tony Ro, Zhigang Zhu

Publications and Research

This paper describes a new posed multimodal emotional dataset and compares human emotion classification based on four different modalities - audio, video, electromyography (EMG), and electroencephalography (EEG). The results are reported with several baseline approaches using various feature extraction techniques and machine-learning algorithms. First, we collected a dataset from 11 human subjects expressing six basic emotions and one neutral emotion. We then extracted features from each modality using principal component analysis, autoencoder, convolution network, and mel-frequency cepstral coefficient (MFCC), some unique to individual modalities. A number of baseline models have been applied to compare the classification performance in emotion recognition, …

The Rise And Fall Of Dopamine: A Two-Stage Model Of The Development And Entrenchment Of Anorexia Nervosa, Jeff A. Beeler, Nesha S. Burghardt

Publications and Research

Dopamine has long been implicated as a critical neural substrate mediating anorexia nervosa (AN). Despite nearly 50 years of research, the putative direction of change in dopamine function remains unclear and no consensus on the mechanistic role of dopamine in AN has been achieved. We hypothesize two stages i n AN– corresponding to initial development and entrenchment– characterized by opposite changes in dopamine. First, caloric restriction, particularly when combined with exercise, triggers an escalating spiral of increasing dopamine that facilitates the behavioral plasticity necessary to establish and reinforce weight-loss behaviors. Second, chronic self-starvation reverses this escalation to reduce or impair …

Toward A Multimodal Computer-Aided Diagnostic Tool For Alzheimer’S Disease Conversion, Danilo Pena, Jessika Suescun, Mya Schiess, Timothy M. Ellmore, Luca Giancardo, Alzheimer’S Disease Neuroimaging Initiative

Publications and Research

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder. It is one of the leading sources of morbidity and mortality in the aging population AD cardinal symptoms include memory and executive function impairment that profoundly alters a patient’s ability to perform activities of daily living. People with mild cognitive impairment (MCI) exhibit many of the early clinical symptoms of patients with AD and have a high chance of converting to AD in their lifetime. Diagnostic criteria rely on clinical assessment and brain magnetic resonance imaging (MRI). Many groups are working to help automate this process to improve the clinical workflow. Current …

The Imaginal Lexicon Of Aging Studies, William Ebenstein

Publications and Research

Aging Studies focuses on the cultural, humanistic and experiential aspects of aging insofar as these are already embedded in literature, art, language and everyday life. The lexicon of this multi-disciplinary field has evolved in response to shifts in cultural attitudes, social roles, and conceptual frameworks. At the same time, many age-related words have links to poetic imagery and ancient myths, and to evocative etymologies that conjure an historical context. The article looks at the ongoing and surprisingly difficult effort to find the right word to call an older person. It reviews the language and literary genres associated with longevity. And, …

The Blind Spots Of Sociotechnical Imaginaries: Covid-19 Scepticism In Brazil, The United Kingdom And The United States, Renan Gonçalves Leonel Da Silva, Larry Au

Publications and Research

During the first wave of the coronavirus pandemic in 2020, experts and policymakers mobilised various slogans to compel the public to help defeat COVID-19. By comparing Brazil, the United Kingdom and the United States, this study shows how dominant sociotechnical imaginaries tied to the slogans were mobilised. We argue that the blind spots of these dominant sociotechnical imaginaries contributed to subversive sociotechnical imaginaries and made room for COVID-19 scepticism. In Brazil, calls to ‘take care of yourself’ contributed to a sceptical stance that individualised responsibility. In the United Kingdom, calls to ‘protect the NHS’ contributed to sceptical accusations of whataboutism …

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. …

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 …

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 …

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. …

Incorporating Race-Centered And Trauma-Informed Practices Into The Reference Interview, Nicole N. Williams, Emma Antobam-Ntekudzi

Publications and Research

Libraries are not race-neutral spaces; from an equity standpoint, treating all students the same does not assist those who may begin at a deficit, such as those from historically underrepresented groups. As supporters of the student body, academic librarians are charged with responding appropriately to their student body in a changing world. Librarians can make a concerted effort not to allow stereotypes and biases to dictate how we interact with students and other library visitors during the reference interview. This begins with taking a critical look at the components of reference service and outlining frameworks and practices that can allow …

Prenatal Exposure To A Natural Disaster And Early Development Of Psychiatric Disorders During The Preschool Years: Stress In Pregnancy Study, Yoko Nomura, Jeffrey H. Newcorn, Christine Ginalis, Catherine Heitz, Jeenia Zaki, Farzana Khan, Mardia Nasrin, Kathryn Sie, Donato Deingeniis, Yasmin L. Hurd

Publications and Research

Background: Growing evidence shows an association between in utero exposure to natural disasters and child behavioral problems, but we still know little about the development of specific psychopathology in preschool-aged children. Methods: Preschool children (n = 163, mean age = 3.19, 85.5% racial and ethnic minorities) and their parents (n = 151) were evaluated annually at ages 2–5 to assess the emergence of psychopathology using the Preschool Age Psychopathological Assessment (PAPA), a parent-report structured diagnostic interview developed for preschool-age children. Sixty-six (40.5%) children were exposed to Sandy Storm (SS) in utero and 97 (59.5%) were not. Survival analysis evaluated patterns …

Do Students’ Questions During Chemistry Lectures Predict Perceived Comprehension And Exam Performance?, Bradley W. Bergey, Jennifer G. Cromley, Avi Kaplan, James D. Bloxton Ii

Publications and Research

Question generation is theorized to support comprehension, self-regulation, and achievement, yet the empirical based for whether and how student-generated questions are associated with comprehension monitoring and whether they predict future performance remain open questions. To address these, we investigated the questions undergraduate students in an introductory chemistry course recorded in question logs across an 8-lecture unit and their relations with post-lecture self-appraisals of comprehension and exam performance. Results indicated that students who generated more questions during lectures, who were able to resolve fewer of their questions, and who generated questions indicating large exam-relevant knowledge gaps reported lower levels of comprehension …
