Description
This qualitative study examines the major changes in relationship closeness of married couples when one spouse acquires a vision disability. Turning Points analysis and Retrospective Interview Technique (RIT) were utilized which required participants to plot their relational journey on a graph after the onset of the disability. A sample of 32 participants generating 100 unique turning points and 32 RIT graphs lent in-depth insight into the less explored area of the impact of a visual disability on marital relationships. A constant comparison method employed for the analysis of these turning points revealed six major categories, which include Change in Relational Dynamics, Realization of the Disability, Regaining Normality in Life, Resilience, Reactions to Assistance, and Dealing with the Disability. These turning points differ in terms of their positive or negative impact on the relational closeness between partners. In addition, the 32 individual RIT graphs were also analyzed and were grouped into four categories based on visual similarity, which include Erratic Relational Restoration, Erratic Relational Increase, Consistent Closeness and Gradual Relational Increase. Results provide theoretical contributions to disability and marriage literature. Implications for the application of turning points to the study of post-disability marital relationships are also discussed, and research directions identified.

Description
Social networking platforms have redefined communication, serving as conduits forswift global information dissemination on contemporary topics and trends. This research
probes information cascade (IC) dynamics, focusing on viral IC, where user-shared information
gains rapid, widespread attention. Implications of IC span advertising, persuasion,
opinion-shaping, and crisis response.
First, this dissertation aims to unravel the context behind viral content, particularly in
the realm of the digital world, introducing a semi-supervised taxonomy induction framework
(STIF). STIF employs state-of-the-art term representation, topical phrase detection,
and clustering to organize terms into a two-level topic taxonomy. Social scientists then
assess the topic clusters for coherence and completeness. STIF proves effective, significantly
reducing human coding efforts (up to 74%) while accurately inducing taxonomies
and term-to-topic mappings due to the high purity of its topics. Second, to profile the
drivers of virality, this study investigates messaging strategies influencing message virality.
Three content-based hypotheses are formulated and tested, demonstrating that incorporation
of “negativity bias,” “causal arguments,” and “threats to personal or societal core
values” - singularly and jointly - significantly enhances message virality on social media,
quantified by retweet counts. Furthermore, the study highlights framing narratives’ pivotal
role in shaping discourse, particularly in adversarial campaigns. An innovative pipeline
for automatic framing detection is introduced, and tested on a collection of texts on the
Russia-Ukraine conflict. Integrating representation learning, overlapping graph-clustering,
and a unique Topic Actor Graph (TAG) synthesis method, the study achieves remarkable
framing detection accuracy. The developed scoring mechanism maps sentences to automatically
detect framing signatures. This pipeline attains an impressive F1 score of 92%
and a 95% weighted accuracy for framing detection on a real-world dataset.
In essence, this dissertation focuses on the multidimensional exploration of information cascade, uncovering the context and drivers of content virality, and automating framing detection.
Through innovative methodologies like STIF, messaging strategy analysis, and
TAG Frames, the research contributes valuable insights into the mechanics of viral content
spread and framing nuances within the digital landscape, enriching fields such as advertisement,
communication, public discourse, and crisis response strategies.
