A harmonic increment provides a new way to improve smooth approximations of the minimum function. In a recent paper, published in the Journal of Inequalities and Applications, Prof. Thomas A. Weber shows how a harmonic-increment transformation brings any smooth estimate that lies strictly below the minimum closer to it, while keeping the improved estimate below the minimum, so it remains a conservative estimate of a worst realization, or weakest link.

A new study has found that in U.S. counties that ended COVID-19 pandemic-era Supplemental Nutrition Assistance Program (SNAP) Emergency Allotments, child maltreatment rates went up. The findings from the study in the American Journal of Preventive Medicine suggest that changes to food assistance programs have consequences that extend beyond food security and also affect child and family well-being.

A review of the research literature spanning the years 2020 to 2026 has found that digital technologies, additive manufacturing and resource recovery are major themes in the transition toward a sustainable, circular economy.

They entail both benefits and risks for employees, bypassed and skip-level managers, and organizations. Their effects also depend on context, as my qualitative exploratory study, published in IEEE Engineering Management Review, suggested.
