The study explores whether combining traditional and digital learning analytics can predict failure in a first‑year CS1 course. Using data from 284 students across four cohorts, the authors identified ten candidate factors and built a logistic regression model that achieved 74.7% accuracy and 0.742 macro F1, with 87% recall for failing students. Weighted academic momentum, basic demographics, and LMS activity emerged as the most predictive features, suggesting that simple digital markers can enable early‑warning systems by week five.

The study evaluates whether large language models (LLMs) with in‑context learning can better identify institution‑specific protected health information (PHI) in electronic health records than existing de‑identification systems. Using 100 pediatric oncology notes from Texas Children’s Hospital, eight LLMs were compared to two purpose‑built systems and pattern‑based baselines under three progressively specific prompts. The best LLM achieved an F1 score of 0.918, recovering 79% of previously missed PHI categories and reaching a recall of 0.981 after iterative prompt refinement, demonstrating that calibrated single‑pass prompting can close the institutional PHI gap while balancing precision and recall.

The paper reports on a series of experiments examining how different forms of directives—such as record pointers, criteria, or combinations—affect an agent’s choice of archived source records when it inherits six one-line memories. Across twelve registered studies involving 14,760 attempts on a single instrument lineage, the authors measured the impact of various directive formats on six direct-provider models, nine OpenRouter-served models, and several Claude and Opus 5 models, noting differences in performance metrics and replication outcomes. The results are purely descriptive, detailing the effects of exact edits on fixed panels with registered intervals and no claim of underlying mechanisms.
