Love’S Dialects: Proposed Additions In Emotionally Focused Therapy For Intercultural Couples, Nicola Heurich

Dissertations

Intercultural romantic relationships have become an increasingly prominent feature of contemporary society due to globalization, migration, and cross-cultural exchange (Livingston & Brown, 2017). However, these partnerships are also associated with elevated levels of relational distress and higher rates of conflict, separation, and divorce, underscoring the need for culturally responsive approaches in couple therapy (Bustamante et al., 2011; Genç & Su, 2021).

Research on intercultural couples remains limited both within and beyond Emotionally Focused Therapy (EFT), and despite increased recognition of cultural factors, there is still insufficient guidance on navigating differing cultural contexts within a dyad (Linhof & Allan, 2018).

Machine Learning For Predictive Energy And Emissions Modeling Of Vehicles And Power Grids In The United States, S M Tanvir Faysal Alam Chowdhoury

Dissertations

The environmental benefits of electric vehicle (EV) adoption depend on more than replacing internal combustion engine vehicles with electric powertrains. EV adoption reshapes electricity demand, interacts with regional generation mixes, and influences travel behavior and congestion, creating a coupled transportation-energy system in which vehicle and power-plant emissions must be evaluated together. This dissertation develops machine-learning frameworks for predicting energy consumption and emissions from vehicles and power grids under rising EV adoption. The first component forecasts grid emissions from EV charging. Using simulation data from NREL's Cambium database, a Prophet-based time-series framework predicts carbon dioxide, nitrous oxide, and methane emission rates …

The Relationship Between Depression And Cognitive Proficiency Index Across Biological Sex, Angela N. Ferdinardo

Dissertations

Depression is a widely studied mood disorder, and understanding its effect on cognitive functioning has become an important area of research. While research has examined relationships among depression, working memory, and cognitive deficits, limited research has explored depressive symptoms and cognitive proficiency across biological sex. Depression manifests similarly in men and women, though men are more likely to experience irritability, impulsivity, and anger, while women tend to experience sadness, stress, and sleep disturbances (Johns Hopkins Medicine, 2023). Women are also more likely to seek treatment and cope differently than men. This study examined the relationship between depression and cognitive proficiency …

The Legacy Of Trauma: Exploring The Effect Of Generational Stress On Gut Health And Mental Well-Being In Black Women, Jocelynn Jones

Dissertations

This dissertation examines how generational trauma and chronic stress may relate to gut health and mood outcomes among Black women. Using a literature review design, this work brings together research on intergenerational trauma, gendered racism, Superwoman Schema, weathering, allostatic load, mood disorders, reproductive health disparities, and the microbiota-gut-brain axis. The central argument is that depression, anxiety, gastrointestinal symptoms, fatigue, reproductive vulnerability, and healthcare mistrust should not be understood as fully separate concerns when they may be shaped by shared stress conditions. The proposed integrated model does not claim that trauma directly causes gut dysbiosis or mood disorders. Instead, it suggests …
