Dyadic Agreement In And Task Correlates To A Measurement Of Conversational Success, Samantha Budge

All Graduate Theses and Dissertations, Fall 2023 to Present

Successful conversation matters for social connection, wellbeing, and quality of life, but people do not always agree on whether a conversation was successful, even when they participated in the same interaction. Conversation is also commonly measured through task success, even though it’s unclear how task success correlates to how successful a conversation feels. This study examined how conversational success is experienced by different conversation partners and whether feeling successful in a conversation is related to how well a task is completed.

Participants took part in a structured conversational task and then rated their own conversational experience using a self-report questionnaire …

A Systematic Review And Meta-Analysis Finds That Psychological Well-Being Predicts All-Cause Mortality Independently Of Psychological Ill-Being., Max Genecov, David Yeager

Department of Psychiatry and Human Behavior Faculty Papers

BACKGROUND: Does psychological well-being (e.g. life satisfaction, happiness, meaning in life) predict the length of a person’s life, or are measures of well-being simply assessing the absence of ill-being (depression, loneliness, sadness) and are therefore redundant with ill-being measures? Individual studies have examined this question by measuring and controlling for both well-being and ill-being, but inconsistent findings have been reported. METHODS: A systematic review and random-effects meta-analysis was conducted on the literature of prospective longitudinal studies linking all-cause mortality to well-being. Studies that controlled for ill-being were compared to studies that did not control for ill-being to identify the unique …

Navigating Medical Ambiguity: A Patient's Perspective On Communication, Timing, And Risk, J. Hansen

Patient Experience Journal

This essay recounts the experience of navigating re-vaccination decisions after an initial diagnosis of vaccine-associated myocarditis. A diagnosis later contested by other specialists. It is not a tale of medical error, but of diagnostic ambiguity and divergent clinical reasoning. My intent is to show how, in the absence of consensus, a patient was compelled to assume a central role in adjudicating between competing medical narratives. Recommendations are offered to make medical advice more available to patients and bridge a growing gap between medicine and the public.

Research On Temporal Knowledge Graph Completion Method For Emergent Events Based On Bigru And Graph Contrastive Learning, Peng Wu, Zhenyu Lu, Xuechen Zhang

Journal of Scientific Information Research

[Purpose/significance] During emergencies, social media short texts contain critical information but are heavily interfered with by noise. Traditional static knowledge graph completion techniques struggle to effectively address their dynamic evolution and data sparsity issues, making it imperative to introduce temporal modeling methods. [Method/process] This study proposes a dynamic completion framework that combines the temporal feature capture capability of Bidirectional Gated Recurrent Units (BiGRU) with the noise-resistant representation learning advantages of Graph Contrastive Learning (GCL). At the completion level, the ConBiTE method is introduced, which captures temporal dependencies through self-attention mechanisms and BiGRU, while leveraging GCL to enhance the completion of …

Thinking With The Feet In The Clinic Of Psychosis, Jed Wilson

Middle Voices

In his later work, Lacan makes occasional reference to the idea of “thinking with the feet.” An equivocal formulation, it first seems to suggest that thought and language can be regarded as physical processes—not occurring in some homunculan disembodied brain or mind, but in the real of the body. Equally, it can call to mind the idea of thinking “on” one’s feet, in the manner of adaptive improvisation. Going further, could we not also say that it points to the possibility of setting something in motion (as in walking, dancing, going somewhere—all the things we do with the feet) as …
