We propose a network reciprocity model in which an agent probabilistically adopts learning or teaching strategies. In the learning adaptation mechanism, an agent may copy a neighbor's strategy through Fermi pairwise comparison. The teaching adaptation mechanism involves an agent imposing its strategy on a neighbor. Our simulations reveal that the reciprocity is significantly affected by the frequency with which learning and teaching agents coexist in a network and by the structure of the network itself.

Automatic segmentation of retinal vessels from retinography images is crucial for timely clinical diagnosis. However, the high cost and specialized expertise required for annotating medical images often result in limited labeled datasets, which constrains the full potential of deep learning methods. Recent advances in self-supervised pretraining using unlabeled data have shown significant benefits for downstream tasks.

Objective: To develop and pilot test a combined-learning intervention for Tanzanian primary healthcare workers on ear and hearing care (EHC), comprising five self-led smartphone-based modules and in-person workshops.
Design: The intervention was piloted with primary healthcare workers in Tanzania. Pre- and post-training surveys assessed knowledge, confidence, and attitudes towards EHC via Likert scales.
