Supervisor-Focused Impression Management And Social Undermining As Self-Enhancing Responses To Perceived Job Insecurity, J. Luke Wiley

Masters Theses and Doctoral Dissertations

Job insecurity has become a more prevalent and harmful issue across many advanced economies. The present study was designed to investigate two ways in which employees may respond to perceived job insecurity. We hypothesized that employees experiencing job insecurity engage in impression management tactics directed at their supervisor (SFIM) or social undermining tactics directed at their coworkers. We further hypothesized that these processes or effects were moderated by employees’ core self-evaluations (CSE). Data were gathered through targeted sampling to workers in the federal government (Sample 1, N = 91), as well as convenience sampling (Sample 2, N = 146). Results …

Personalized And Adaptive Therapeutic Music Generation From Biosignals Using Knowledge-Guided Multimodal Large Language Models, Amin Amiri

Masters Theses and Doctoral Dissertations

Multimodal generative models are reshaping digital therapeutics by enabling real-time synthesis of personalized content aligned with a user’s physiological and affective state. However, existing systems remain fragmented across modalities and often lack a unified framework that can jointly represent biosignals, natural language intent, music, and video under long-context constraints. This dissertation presents an end-to-end multimodal large language model ecosystem for personalized therapeutic music generation that combines discrete tokenization, evidence-grounded reasoning, and stabilized preference alignment. At the representation layer, the dissertation develops a family of tokenizers that convert continuous biomedical and media signals into compact discrete sequences for transformer-based modeling.

Phenotypic Contribution And Regulation Of Vibrio Parahaemolyticus Cold-Shock Protein Homologue Vp1889, Oleg Borisovich Ermolinsky

Theses and Dissertations

Vibrio parahaemolyticus is the primary causative agent of a form of gastroenteritis called vibriosis commonly acquired from ingestion of raw and undercooked seafood. The primary mitigation of seafood-borne illnesses is immediate storage on ice following catch, which inhibits bacterial metabolism and replication. Mesophilic bacteria such as V. parahaemolyticus induce expression of cold-shock proteins in a process named the cold shock response, which facilitates survival at low temperatures. V. parahaemolyticus bears 3 homologues of the major Escherichia coli cold-shock protein CspA, an RNA chaperone. Induction of E. coli CspA at low temperatures depends on autogenous modulation by its mRNA structure, which …

From Witness To Weapon: How Elizabeth Barrett Browning’S “The Cry Of The Children” Embodies And Transforms The Rhetorical Situation, Elyssa Vianey Solis

Theses and Dissertations

Elizabeth Barrett Browning’s “The Cry of the Children” employs trauma-driven rhetoric to expose Victorian child labor exploitation.

Combining literary analysis with rhetorical theory, this research contextualizes the poem within 19th-century industrial exploitation, showing how Browning transforms documentary evidence like the 1842 Children’s Employment Commission Report into emotional testimony. Visceral imagery, ironic juxtaposition, and embodied suffering weaponize pathos to reveal systemic abuse and moral urgency. Applying Lloyd Bitzer’s and Richard Vatz’s theories, we can posit that Browning both responds to and defines the crisis, merging poetic protest with social reform as civic intervention.

By engaging Bitzer and Vatz, this paper argues …

Structure–Property Engineering Of Sn-Based Hybrid Perovskites Via Bulky Organic Cation Incorporation: From 3d To 2d Architectures, Kevin Alejandro

Theses and Dissertations

This thesis investigates tin-based hybrid organic/inorganic perovskites (HOIPs) as a lead-free alternative to silicon solar cells. To manipulate optoelectronic and efficiency of the semiconductors, methylammonium was substituted with bulky propylammonium and tetrabutylammonium cations to induce quasi-2D/3D Ruddlesden-Popper phases. X-Ray Diffraction confirmed 2D layered phases in propylammonium hybrids (5-15%), while tetrabutylammonium hybrids faced steric limits, triggering vacancy ordered perovskite phases at 1% concentration. Optical analysis showed a bandgap narrowing from 1.30 eV to 1.26 eV with increased substitution. Although photovoltaic performance generally declined, the 10% propylammonium hybrid achieved the highest fill factor of ~0.79, indicating superior internal charge transport. This work …
