A productivity dashboard for hospitals: an empirical study

Health information systems are key assets in managing health units’ daily operations. Nevertheless, literature is scarce concerning information systems for increasing and managing hospital productivity. This study aims at filling such gap through an empirical research based on large Portuguese hospital. Specifically, a dashboard prototype is proposed addressing productivity indicators in areas such as assistance, hospitalization, surgery, among others. This dashboard is tuned using a design science research approach where health experts successively validate the prototype. Interviews are conducted to assess the benefits of using our proposal to manage productivity on a daily basis.info:eu-repo/semantics/acceptedVersio

Spin dimer ground state driven by consecutive charge and orbital ordering transitions in the anionic mixed valence compound Rb4O6

Recently, a Verwey type transition in the mixed valence alkali sesquioxide Cs4O6 was deduced from the charge ordering of molecular peroxide O2 amp; 8722;2 and superoxide O amp; 8722;2 anions accompanied by the structural transformation and a dramatic change in electronic conductivity [Adler et al., Sci. Adv. 4, eaap7581 2018 ]. Here, we report that in the sister compound Rb4O6, a similar Verwey type charge ordering transition is strongly linked to O amp; 8722;2 orbital and spin dynamics. On cooling, a powder neutron diffraction experiment reveals a charge ordering anda cubic to tetragonal transition at TCO 290 K, which is followed by a further structural instability at Ts 92 K that involves an additional reorientation of magnetic O amp; 8722;2 anions. Magnetic resonance techniques supported by density functional theory computations suggest the emergence of a peculiar type of amp; 960; amp; 8727; orbital ordering of the magnetically active O amp; 8722;2 units, which promotes the formation of a quantum spin state composed of weakly coupled spin dimers. These results reveal that as in 3d transition metal compounds, also in the amp; 960; amp; 8727; open shell alkali sesquioxides the interplay between Jahn Teller like electron lattice coupling and Kugel Khomskii type superexchange determines the nature of orbital ordering and the magnetic ground stat
