Faculty, Staff and Student Publications

Sleep dysfunction is common among individuals with schizophrenia spectrum disorders (SSD). Sleep duration and other sleep quality metrics are associated with worse patient clinical and social outcomes. We examined if accumulative stress, gray matter structural volume measured with high-resolution structural brain MRI, diffusion tensor imaging measures of white matter microstructure, and psychopathology (for the schizophrenia group) may act as predictors of sleep quality and compared individuals with SSD (N = 101) and healthy controls (N = 86). We created an adjusted Pittsburgh Sleep Quality Index (PSQI-A) score to measure sleep quality and account for abnormally long sleep duration as dysfunctional. …

The Feelit System: Application Content-Aware Perspectives And Challenges On Understanding User Likes In Social Network Posts, Konstantinos Theocharidis, Hady W. Lauw, Panagiotis Karras

Research Collection School Of Computing and Information Systems

In a series of our prior works, we study influence and subscription maximization problems in social networks that are based on posts having influential content; as content we consider a set of features where each feature corresponds to a specific social network page, whereas influence and subscription relate to gaining the postlike and subscription-to-brand page of targeted users, respectively; subscription is conceptually achieved as repetitive influence on users. So, both influence and subscription depend on content that gains the likes of users; however, to be realistic, modeling and estimating such likes is a complex problem that has not been adequately …

Shaping Occupational Self-Efficacy In Complex Jobs: Cognitive Flexibility, Role Stressors, And The Workplace, Carolyn Henn

Graduate Theses, Dissertations, and Problem Reports (ETD)

Career advancement in many professions requires employees to move beyond a single specialized role and perform effectively across different responsibilities. These complex jobs often combine technical work, project oversight, client interaction, financial accountability, and coordination with others. Successfully managing these overlapping responsibilities requires strong occupational self-efficacy, but not much is known about the factors that shape employees’ confidence in their ability to perform in complex jobs, particularly under role stress. This study uses cross-sectional survey data from 132 full-time professionals working in complex, multi-role jobs across a range of industries to examine how cognitive flexibility, role stressors, and job demands …

The Effects Of Stress-Related Hormones On Excitatory Synapse Formation, Autumn C. Garvey

Honors Undergraduate Theses

Stress profoundly influences brain function through neuromodulatory hormones that regulate synaptic plasticity, yet how temporal patterns of hormone exposure shape excitatory synapse formation remains poorly understood. This study investigates how exposure to stress hormones, norepinephrine and cortisol, affects excitatory synapse development. While existing research primarily compares concentration models, real-world stress occurs in variable patterns that may produce distinct neural outcomes. To address this gap, differentiated Neuro2A neuronal cells are exposed to norepinephrine or cortisol under a continuous treatment paradigm designed to model chronic stress conditions. Following treatment, immunofluorescence imaging is utilized to quantify excitatory synapse formation through analysis of presynaptic …

Modern Psychological Distress: An Expressionist Lens, Abigail Adell

Scripps Senior Theses
