Unlabelled: School meals play a critical role in supporting students' biopsychosocial growth, development, learning, academic performance, and the establishment of healthy eating habits. In public institutions, food procurement is conducted through formal public procurement processes. However, emphasizing cost-effectiveness in bidding criteria, such as prioritizing the lowest product price, may inadvertently encourage the acquisition of foods high in critical nutrients.

Auction-based federated learning (AFL) has emerged as an efficient and fair approach to incentivize data owners (DOs) to contribute to federated model training, garnering extensive interest. However, the important problem of helping data consumers (DCs) bid for DOs in competitive AFL settings remains open. Existing work simply treats that the actual cost paid by a winning DC (i.

Importance: The Medicare Competitive Bidding Program (CBP), a policy that reduced durable medical equipment prices, was implemented starting in 2011. Legislation introduced in 2024 aims to remove supplemental oxygen from the CBP because of concerns that recent decreases in oxygen prescribing are due to lower prices set by the CBP, which may have decreased supply and, in turn, limited oxygen access for patients with chronic lung diseases. However, low-value prescribing of oxygen is also prevalent in practice, and decreased oxygen prescription rates may not have necessarily caused harm.

Article Synopsis
- The study investigates how private Medicare Advantage (MA) plans adjusted to slower growth in federal payments after the Affordable Care Act (ACA) by analyzing data from 2006 to 2019.
- Researchers compared changes in bids, rebates, and premiums in counties with varying levels of subsidy adjustments before and after the ACA, using fixed effects regression models.
- Findings reveal that while average benchmarks dropped significantly post-ACA, plans increased and decreased their bids proportionately, altered minor benefits more drastically, and showed varying responsiveness based on market competitiveness, with less competitive markets responding more heavily to payment changes.
