Unobtrusive stress detection using wearables: application and challenges in a university setting by Peter Neigel, Andrew Vargo, Benjamin Tag, Koichi Kise

“…We identify potential stress patterns by observing elevated waking heart rate (HR) and maximum waking HR, supported by related metrics such as sleep HR, sleep heart rate variability (HRV), activity patterns, and sleep phases.ResultsThe physiological changes align with significant academic and societal events, indicating a strong link to stress.DiscussionOur findings demonstrate the potential of consumer wearables to detect collective changes in stress biomarkers within a cohort using in-the-wild data, i.e., data that is noisy and has gaps. …”

Spatial Inequality and Accessibility of Senior High School Education in Bonebolango Regency by Aljunaid Bakari, Firman Sidik

“…The results of this study show that the availability of high school facilities in Bonebolango Regency has not met the needs of the upper school-age community, because it has not been able to accommodate 80% of the high school age population in each sub-district. The occupancy rate is also uneven, with four high schools having an occupancy rate above 80% of the temporary capacity and 11 high schools having an occupancy rate of less than 50% of their capacity Based on the analysis of the nearest neighbors, the distribution pattern of high schools in Bonebolango Regency is relatively random, with a value of 0.975337 and a z-score of -0.030915. …”
