Isometries and Hermitian Operators on Zygmund spaces

In this paper we characterize the isometries of subspaces of the little Zygmund space. We show that the isometries of these spaces are surjective and represented as integral operators. We also show that all hermitian operators on these settings are bounded

Achieving compliance with healthcare waste management regulations: empirical evidence from small European healthcare units

Healthcare units generate substantial amounts of hazardous or potentially hazardous wastes as by-products of their medical services. The inappropriate management of these wastes poses significant risks to people and the environment. In Portugal, as in other EU countries, the collection, storage, treatment and disposal of healthcare waste is regulated by law. Although legal provisions covering the safe management of healthcare waste date back to the 1990s, little is known about the compliance of Portuguese healthcare units with the relevant regulations. In this study we evaluate the extent of compliance by small private healthcare units with current waste management regulations, and its determinants. Recent estimates indicate that these units account for at least 20% of the healthcare waste produced at the national level. Their large numbers, however, make monitoring and government control of their compliance with legislative requirements problematic. Using data collected by a national survey of over 700 private healthcare units, we find that the majority of these units do not comply with current waste management regulations. An estimated generalized linear model uncovers a regional effect on the degree of compliance, which is also influenced by the type of healthcare delivered, use of service providers, implementation of regular internal audits, etc. The strongest factor influencing the degree of compliance is, however, education and training. This result is extremely important for policy because it shows empirically that providing education and training for all healthcare workers on medical waste issues is crucial in order to attain proper practices in healthcare waste management and compliance with regulations.Waste management; medical waste; legislation; compliance

Strategic behavior at trial-The production, reporting, and evaluation of complex evidence

Recent game-theoretic analyses of the adversarial process have focused on the hability of courts to render accurate verdicts in light of selectivity reported evidence. This paper generalizes previous work by developing a game where the court´s decision to weigh evidence and litigants' information-gathering and reporting strategies are endogenously determined, and examines the effects on the players' equilibrium strategies of varying the informational endowments of the litigants concerning the true value of the parameter under dispute. We find that litigants' strategies are driven by their knowledge of the court's potential behavior and prior beliefs, which are non-neutral with respect to trial results.adversarial process, information provision, weighing of evidence
