Racism In The Science And Practice Of Psychotherapy, Richard E. Redding, Craig L. Frisby

Psychology Faculty Articles and Research

We discuss a recent controversy that occurred in The Cognitive Behavioural Therapist over whether Lilienfeld’s critical views on microaggressions theory and research reflect racist beliefs, as alleged by some. This is one of many recent examples of a profoundly antiscientific practice whereby racism allegations chill scientific debate and open inquiry on important research issues. This produces an overtly politicized science that has a corrosive effect on scientific progress and ultimately the useful application of research in clinical practice. The microaggressions controversy provides an especially useful vehicle for challenging this state of affairs given the widespread application of microaggressions theory, including …

Evaluating Chest-Worn Light Logger Adherence: Development And Application Of A Wear/Non-Wear Model, Carlyn Patterson Gentile, Adah Thomas, Ryan Shah, Blanca Marquez De Prado, Nichelle Raj, Christina Szperka, Geoffrey Aguirre

Student Papers, Posters & Projects

Light exposure plays an important role in overall health because it entrains circadian rhythms. Recent technological advances in wearable light loggers allow measurement daily light exposure habits. Using a chest-worn light logger, our goal was to (1) develop methodology for differentiating adherent versus non-adherent use, and (2) define differences in lighting intensity in indoor and outdoor environments, to improve data reliability in future clinical studies using this technology. Four testers used a 10-channel chest worn light logging device under different conditions of wear and non-wear (experiment 1), and another tester made measurements with the light logger across a variety of …

Shared Premotor Resources Underlie Dual-Task Interference Between Speech And Balance, Weina Lu, Sasha Lifton Lewis, Zoey Wire, Ingo Helmich

Exercise and Sport Studies: Faculty Publications

Humans frequently speak while standing, potentially engaging overlapping motor-cognitive resources. Dual-task paradigms with increased motor-cognitive demands reliably impair postural control, presumably due to competition for shared neural resources. The premotor cortex is critically involved in balance stabilization and in resolving competing motor plans and is also engaged during processing of action-related language. We therefore hypothesized that a central processing bottleneck emerges in the PMC when speaking and controlling posture simultaneously. Forty-one right-handed healthy adults (25 female, 16 male) maintained an upright stance while either verbally describing or mentally imagining navigation through a visually presented maze from an egocentric or allocentric …

Chromatin Insulators Homie And Nhomie Can Interact With Distant Copies Either Together Or Separately, With Distinct Outcomes For Enhancer-Promoter Interactions, Miki Fujioka, Wenfan Ke, Paul Schedl, James B. Jaynes

Department of Biochemistry and Molecular Biology Faculty Papers

Chromatin insulators, a.k.a. boundary elements, separate regions of the chromosome with distinct chromatin characteristics, including distinct histone modifications. This activity affects gene expression by allowing chromatin domains to be stably regulated and maintained. Insulators also block enhancer-promoter interactions and, somewhat paradoxically, facilitate other interactions, particularly when they stitch together distant regions of the chromosome by pairing with specific partners. Here we explore how long-range interactions facilitated by insulator pairing are affected by the presence of two potentially competing partners. Our results show that when two partners are present, they can reduce each other's effects on distant gene expression, suggesting that …

Stress-Activated Pathways Mediate Pfas Effects On Human Placental Syncytiotrophoblast Cells., Keisuke Kozai, Kaela Varberg

Manuscripts, Articles, Book Chapters and Other Papers

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental pollutants associated with placenta-mediated pregnancy complications, including preeclampsia, fetal growth restriction, and preterm birth. The syncytiotrophoblast (STB), which forms the placental barrier at the maternal-fetal interface and is directly exposed to maternal blood, is a primary site of PFAS exposure. Although PFAS induce STB apoptosis, the upstream stress-signaling pathways involved remain poorly defined. Here, we investigated stress-responsive signaling mechanisms mediating PFAS-induced STB cell death. STB differentiated from human trophoblast stem cells were exposed to vehicle or an environmentally relevant mixture of 5 PFAS (perfluorooctanoic acid, perfluorooctanesulfonic acid, perfluorohexane sulfonate, perfluorononanoic acid, and …

Simon, Qi Wang, Emily N C Manoogian, Satchindananda Panda, Suryeon Ryu, Zan Gao, Caleb Griffiths, Erika Helgeson, Douglas G. Mashek, Niki Oldenburg, Lisa Senye Chow

Manuscripts, Articles, Book Chapters and Other Papers

Background/Objectives: Circadian misalignment, including mistimed sleep or eating, is associated with altered glucose metabolism. The importance of eating window timing for time-restricted eating (TRE) is increasingly recognized. This secondary analysis examined associations between meal to sleep timing intervals and glycemic parameters in individuals with obesity across three dietary interventions [TRE, CR: caloric restriction, and UE: unrestricted eating]. Methods: Participants aged 18-65 years with obesity were randomized to a 12-week intervention: TRE (8 h eating window), CR (15% reduction in daily caloric intake), or UE (usual eating habits). CGM and actigraphy were assessed over two weeks at baseline and end-intervention. Mixed …

Imaging And Non-Imaging Approaches For The Diagnosis And Monitoring Of Necrotizing Enterocolitis-What Lies Ahead?, Indrani Bhattacharjee, Catalina Le Cacheux, Eric B. Ortigoza, Jonathan Dillman, Sherwin S. Chan, Alain Cuna

Manuscripts, Articles, Book Chapters and Other Papers

Necrotizing enterocolitis (NEC) remains one of the most serious gastrointestinal emergencies in preterm infants, and imaging plays a central role in diagnosis and clinical management. Historically, evaluation has relied primarily on abdominal radiography, which remains widely available and embedded in established diagnostic frameworks. However, the hallmark radiographic signs of NEC (i.e., pneumatosis intestinalis, portal venous gas, and free air) reflect relatively advanced manifestations of intestinal injury that indicate established mucosal disruption or transmural necrosis. Bowel ultrasound has increasingly complemented radiography by enabling real-time assessment of bowel wall integrity, perfusion, motility, and intra-abdominal fluid, providing physiologic information that may refine clinical …

Expanding Transmobilities: Understanding Genderdiverse And Transgender Travel Behavior Through An Art-Informed Methodology, Nicholas Michael Puczkowskyj

Dissertations and Theses

Transgender and genderdiverse people face discrimination and harassment in public when making trips in Portland, OR. People who identify as genderdiverse or transgender create unique travel behavior due to the influence of their internalized and expressed gender identity and through interactions in public. This dissertation examines how gender identity influences the travel behavior of genderdiverse and transgender people and how these experiences influence their subjective wellbeing when making trips in Portland, Oregon. Traditional one-on-one interviews were conducted in conjunction with allowing the interviewees to produce art as a non-verbal form of expression and communication of their experiences making trips in …

A Scoping Review Of Ai Literacy: Implications For Governance And Public Policy, Anabel Quan-Haase, Katharine Willis, Hillary Anderson, Selena Gignac, Takuya Maeda

School of Art, Design and Architecture

AI literacy can be situated at the intersection of other types of literacy such as media literacy anddigital literacy, but the concept is distinct. What complicates our understanding of AI literacy is thatAI is highly opaque and black-box, creating obstacles to grasping what these systems are doing andhow (Burrell, 2016; Petrovčič, et al. 2024). This requires an interdisciplinary effort in conceptualizingand mapping AI literacy. Based on our analyses of the current literature, we see five different typesof conceptualizations of AI literacy:1.Competency-based approaches: focused on skills, knowledge, and ethical use of AI.2.Awareness-oriented approaches: centered on recognizing the presence and influence of …

Entre La Lucha: Familismo And Well-Being Of Latino Immigrant Families Navigating Manual Labor And Anti-Immigrant Sentiment, Faviola Robles Saenz

Dissertations and Theses

The United States' history of treatment toward Latino immigrants has been shaped by anti-immigrant sentiment and exploitative labor practices, creating psychological violence that harms their families' well-being. Although previous research has examined anti-immigrant sentiment, labor conditions, and familismo among Latinos, these areas are often studied in isolation, with limited attention to their intersections and how they are experienced across generations. Informed by history, prior research, and my lived experiences, this study qualitatively explored the intersections of anti-immigrant sentiment and parents' manual labor to understand how these contexts shape familismo and well-being among Latino immigrant families. This work was grounded in …

Profiles Of Family Engagement In Head Start, Elizabeth Jane Tremaine

Dissertations and Theses

Families of young children are active participants in their child's transition to kindergarten. Head Start is designed to facilitate families' engagement in their child's learning experiences (Head Start Parent, Family, and Community Engagement Framework, 2018). This study explores family engagement in Head Start, its changes across the transition into kindergarten, and its relation to children's development of social-emotional and executive function skills.

The current study addresses limitations of previous research by relying on family perspectives of family engagement, approaching family engagement as a developmental concept, and taking a person-centered analytic approach that accounts for the multi-dimensionality of family engagement. This …

Does A Common Threat Unite?: Alliance Formation In East Asia Under Chinese Pressure, Sean G. Mcclellan

Honors Theses

The study explores whether a shared geopolitical threat fosters alliance formation among East Asian nations, focusing on Taiwan, Japan, and South Korea in the context of increasing Chinese influence. Integrating insights from international relations theory and social psychology—particularly Realistic Conflict Theory and the out-group unifying effect—the research evaluates whether perceived Chinese aggression corresponds with increased positive sentiment toward the United States. Utilizing data from the Asian Barometer Survey, linear regression analysis is conducted to assess how perceptions of Chinese and U.S. influence, democratic values, and political affiliation shape public attitudes. Results show that while negative views of Chinese and U.S. …

The Employment Situation Of Veterans: May 2026, Institute For Veterans And Military Families At Syracuse University

Institute for Veterans and Military Families

The May 2026 employment report highlights improving labor conditions for U.S. veterans, with unemployment declining from 3.6% in April to 3.2% in May..pdf) Despite this progress, Post-9/11 veterans experienced a slight increase to 4.1%. Younger veterans continue to face higher unemployment rates than their nonveteran peers, while older veterans maintain relatively low rates. Long-term unemployment remains a concern, with over half of unemployed veterans out of work for 15 weeks or more. Unemployment decreased across most demographic groups, including women and minority veterans, often falling below nonveteran rates, indicating gradual but uneven improvement in veterans’ employment outcomes nationwide.

Uncovering Dkk1 As A Therapeutically Relevant Target In Aggressive Er+ Breast Cancer Using A Novel Antiestrogen, Kristen Young

Dissertations

Over 70 percent of breast cancers are estrogen receptor-positive (ERα+), meaning that the hormone estrogen drives tumor growth. Although first-line targeted therapies that directly block ERα from hormone-dependent pathologies are initially effective, almost half of patients ultimately progress. These patients show high mutational rates to the ESR1 gene that encodes for ERα. A hotspot missense tyrosine to serine mutation at position 537 (Y537S) initiates hormone-independent, allele-specific transcriptional programs that increase metastasis. While next-generation ERα-targeted therapies show promise, benefits are often limited compared to standard-of-care. Understanding the mechanisms of action used by the Y537S ESR1 breast cancer cells to evade therapeutic …

Synthesis And Characterization Of Organometallic Polymers And Their Cytotoxicity Towards Human Cancer Cell Lines, Paul Peter Slawek

Electronic Theses and Dissertations

This research aimed to synthesize organometallic polymers from dialkyl (methyl, ethyl, butyl, cyclohexyl, and octyl) and diaryl (phenyl) tin dichlorides and three organic monomers, dipicolinic acid (DPA), chloramphenicol (CH), and isomannide (IS), using interfacial polymerization. Structure-activity relationships were investigated through physicochemical characterization (light-scattering photometry, proton NMR, and IR spectroscopy) and cytotoxicity was evaluated against six human cancer cell lines (AsPC-1, PANC-1, MCF-7, MDA-MB-231, HT-29, PC-3), with cisplatin serving as the reference standard.

Five DPA/tin polymers were synthesized, with IC₅₀ values in the range of 0.60–0.71 μg/mL. Their cytotoxicity was significantly lower than that of cisplatin (0.0023-0.044 μg/mL), suggesting that …

Discovery Of Bmi-Associated Gut Microbiome Signatures In The Awi-Gen 2 Cohort, Meriem Yagoubi

Theses and Dissertations

Obesity is increasing across sub-Saharan Africa amid rapid dietary, environmental, and urbanization transitions, yet the gut microbiome features associated with adiposity in African populations remain under-characterized. This study investigated whether species-level gut microbiome composition is associated with body mass index (BMI) in the AWI-Gen 2 cohort, and whether BMI-associated microbial signals remain detectable after accounting for the dominant geographic structure of the microbiome. Gut microbiome community structure and diversity were characterized across 1,665 participants, and differential abundance analysis was used to identify taxa associated with BMI after controlling for study site. Machine learning models were then trained to assess how …

Koba-Nielsen Local Zeta Functions, Convex Subsets, And Generalized Selberg-Mehta-Macdonald And Dotsenko-Fateev-Like Integrals, Willem Veys, Wilson A. Zuniga-Galindo

School of Mathematical & Statistical Sciences Faculty Publications

The Koba-Nielsen local zeta functions are integrals depending on several complex parameters, used to regularize the Koba-Nielsen string amplitudes. These integrals are convergent and admit meromorphic continuations in the complex parameters. In the original case, the integration is carried out on the n-dimensional Euclidean space. In this work, the integration is over a variety of (bounded or unbounded) convex subsets; the resulting integrals also admit meromorphic continuations in the complex parameters. We describe the meromorphic continuation's polar locus explicitly, using the technique of embedded resolution. This result can be reinterpreted as saying that the meromorphic continuations are weighted sums of …

Group Operations For Concurrent Binary Search Trees, Theodora R. Cooper

Dissertations and Theses

A group operation performs multiple independent instances of the same operation on a data structure. For example, a group operation might look up 10 different keys in a binary search tree, returning 10 results. Chen et al introduced group prefetching, an optimization for group operations on linked data structures that improves throughput by overlapping memory access latencies for independent traversals. Constructing code that maximizes this throughput benefit by fully leveraging the instruction- and memory-level parallelism available on modern hardware is challenging because of overhead, interactions with the cache hierarchy, and other factors.

To address these challenges, we present two new …

Growth In Early Infancy Drives Optimal Brain Functional Connectivity Which Predicts Cognitive Flexibility In Later Childhood, Chiara Bulgarelli, Anna Blasi, Samantha Mccann, Bosiljka Milosavljevic, Giulia Ghillia, Ebrima Mbye, Ebou Touray, Tijan Fadera, Lena Acolatse, Sophie E Moore, Sarah Lloyd-Fox, Clare E Elwell, Adam T Eggebrecht, Bright Study Team

2020-Current year OA Pubs

Functional brain network organisation, measured by functional connectivity (FC), reflects key neurodevelopmental processes for healthy development. Early exposure to adversity, for example undernutrition, affects neurodevelopment, observable via disrupted FC, and leads to poorer outcomes from preschool age onwards. We assessed longitudinally the impact of early growth trajectories on developmental FC in a rural Gambian population from age 5-24 months. To investigate how these early trajectories relate to later childhood outcomes, we assessed cognitive flexibility at 3-5 years. We observed that early physical growth before the fifth month of life drove optimal developmental trajectories of FC that in turn predicted cognitive …

Panel Discussion: Recognizing Research Data In Tenure & Promotion: Turning Policy Principles Into Practice, John Chodacki, Kristi Holmes, Sean Mooney, Su Nee Goh

FORCE 2026

Despite growing attention to open science and data sharing, most institutional reporting processes as well as assessment guidelines (e.g. for tenure and promotion) still fail to recognize research data as a first-class scholarly output. This gap hinders progress in open data practices and efforts to make research outputs more open, reusable, and reproducible.

This session builds on the work of the Implementing Data Evaluation in Academia initiative, which has developed a maturity model for data evaluation at institutions, template policy language for data recognition, and case studies from early-adopter universities. The panel will bring perspectives from institutions at varying stages …

Developing An Assessment Framework To Support Critical Evaluation Of Ai-Powered Academic Search Engines, Huajin Wang

FORCE 2026

As AI-powered tools are emerging in all aspects of research, it’s challenging for researchers, students, and librarians alike to assess the benefit, usefulness, and risks associated with a new AI-powered tool or AI-enhanced features of an existing one. To address this challenge, Carnegie Mellon University Libraries is developing a Tool Evaluation Framework to help users understand how AI-powered tools work, initially focused on AI-enhanced academic search engines.
