Redefining value creation innovation in healthcare organizations: the catalytic role of Lean Management, Six Sigma and Patient Safety
No full textRight Vertebral Artery Intermittent Flow Reversal Due to Innominate Artery Dissection
No full textHere, we describe a case of an asymptomatic 73-year-old female patient who suffered from type A acute aortic dissection with epiaortic arteries involvement and underwent surgical operation 9 years ago. A follow-up color Doppler ultrasound revealed a right vertebral artery intermittent flow reversal due to innominate artery dissection. To our knowledge, no previous studies have reported this intermittent flow reversal; therefore, supra-aortic trunks should be considered among the possible causes of vertebral artery flow reversal
Preliminary Assessment of the Impact of the Copernicus Imaging Microwave Radiometer (CIMR) on the Copernicus Mediterranean Sea Surface Temperature L4 Analyses
No full textThis study evaluates the potential impact of the Copernicus Imaging Microwave Radiometer (CIMR) mission on the sea surface temperature (SST) products of the Mediterranean Sea. Currently, infrared (IR) radiometers provide accurate, high-resolution SST measurements, but they are limited by their inability to see through clouds. Passive microwave (PMW) radiometers, on the other hand, offer monitoring capabilities in almost all weather conditions but typically at lower spatial resolutions. The CIMR mission represents a notable advance in microwave remote sensing of SSTs, as it will ensure a ≤15 km spatial resolution in the recovered SST field. Using an observing system simulation experiment (OSSE), this study evaluates the effect of inserting synthetic CIMR observations into the Copernicus Mediterranean SST analysis system, which is based on an optimal interpolation (OI) algorithm. The OSSE was conducted using data for the year 2017, including daily SST and salinity outputs from a Mediterranean Sea model, hourly precipitation rates from the IMERG, and wind and cloud cover data from ERA5. The results suggest that the improved spatial resolution and accuracy of the CIMR could potentially improve SST retrievals in the Mediterranean Sea, offering better insights for climate and environmental monitoring in semi-closed basins. Including CIMR data in the OI algorithm reduced the mean error and root mean square error (RMSE) of the SST analysis, especially under conditions of low IR coverage. The greatest improvements were found to occur in July, corresponding to coastal upwelling and Atlantic inflow into the Alboran Sea. Improvements ranged from 16% to 29%, with an overall improvement of 26% for the full year of 2017. In conclusion, this preliminary study indicates that Copernicus Mediterranean Sea HR SST products could benefit from the inclusion of the CIMR in the current IR sensor constellation
Assessing the role of urban green vegetation in mitigating land surface temperature in Naples (Italy) using Landsat-9 and GIS techniques
No full textUrban vegetation plays a fundamental role in mitigating Urban Heat Island (UHI) effect, especially in densely built environments. This study investigated the spatial variation of Land Surface Temperature (LST) in Naples (Italy), by integrating Landsat-9 thermal imagery and GIS tools. Two complementary approaches are applied: Local Climate Zones (LCZs) are used as a preliminary analysis to determine the influence of urban morphology on LST, while Corine Land Cover (CLC) data are employed to evaluate thermal gradients around four urban areas using concentric buffers at 500, 1000, and 1500 m. LST is derived applying the Split Window algorithm for four clear-sky summer days in 2023, complemented by a supplementary winter analysis. Results show significant cooling effects in proximity to urban green areas, with maximum LST differences of +8.5°C in industrial or commercial units, while more moderate gradients are observed in agricultural and semi-natural areas. The LCZ-based analysis confirmed significant differences in LST between the different zones, with built-up areas warmer than vegetated areas. This study proposes a replicable approach that combines LCZ analysis and CLC-based thermal gradient assessment, providing insights to support UHI mitigation strategies in Mediterranean cities, where heterogeneous land cover and urban density intensify thermal stress
No Country for Young People: Intergenerational Burdens of COVID-19 Policy Responses
No full textThis study examines intergenerational welfare e¤ects of COVID-19 policy responses,
focusing on containment measures, ...scal expansions, and debt repayment schemes.
Using a life-cycle model, we ...nd: (i) without containment, welfare losses fall mainly
on older agents via demographics; (ii) lockdowns shift burdens toward younger cohorts;
(iii) debt-...nanced ...scal expansions have modest e¤ects compared to social distancing;
and (iv) debt repayment strategies are decisive—front-loaded repayment penalizes the
young, while postponed repayment favors the old. These results highlight critical tradeo¤

L’imposta personale sul reddito complessivo e la crisi della progressività
No full textPartendo dall'emersione storica delle imposte personali sul reddito quali strumenti per perseguire, al di là della mera raccolta del gettito, obiettivi di natura solidaristica e redistributiva, il contributo esamina criticamente il sistema tributario italiano e la vicenda "recessiva" dell'attuazione del principio costituzionale di progressività nell'imposta personale sul reddito complessivo. Le nuove forme assunte dalla ricchezza negli ultimi decenni richiedono di misurare la capacità contributiva dei soggetti non più solo sul reddito personale, ma anche sul patrimonio, sui consumi e, più in generale, sul contesto familiare e lavorativo nel quale il soggetto si muove
