Legislazione regionale siciliana e controllo di costituzionalità
No full textil lavoro è suddiviso in due parti: prima parte di Giuseppe Verde , circa 150 pagine. Seconda parte di Giovanni Scala, circa 150 pagine.
Nella prima parte si ricostruisce l'andamento della legislazione regionale Siciliana con una particolare attenzione al sistema delle fonti. Nella seconda parte si ricostruisce lo svolgimento del controllo di costituzionalità cui è sottoposta la legislazione regionale Siciliana, alla luce dell'art. 10 della Legge costituzionale n. 3/2001 e della giurisprudenza costituzionale
Classification and regression model to manage the hospitalization for laparoscopic cholecystectomy
No full textAbstract Gallstone disease (GD) is one of the most common morbidities in the world. Laparoscopic Cholecystectomy (LC) is currently the gold standard, performed in about 96% of cases. The most affected groups are the elderly, who generally have higher pre- and post-operative morbidity and mortality rates and longer Length of Stay (LOS). For this reason, several indicators have been defined to improve quality and efficiency and contain costs. In this study, data from patients who underwent LC at the “San Giovanni di Dio e Ruggi d’Aragona” University Hospital of Salerno in the years 2010–2020 were processed using a Multiple Linear Regression (MLR) model and Classification algorithms in order to identify the variables that most influence LOS. The results of the 2352 patients analyzed showed that pre-operative LOS and Age were the independent variables that most affected LOS. In particular, MLR model had a R2 value equal to 0.537 and the best classification algorithm, Decision Tree, had an accuracy greater than 83%. In conclusion, both the MLR model and the classification algorithms produced significant results that could provide important support in the management of this healthcare process

Insights into Quantum Contextuality and Bell Nonclassicality: A Study on Random Pure Two-Qubit Systems
No full textWe explore the relationship between Kochen-Specker quantum contextuality and
Bell-nonclassicality for ensembles of two-qubit pure states. We present a
comparative analysis showing that the violation of a noncontextuality
inequality on a given quantum state reverberates on the Bell-nonclassicality of
the considered state. In particular, we use suitable inequalities that are
experimentally testable to detect quantum contextuality and nonlocality for
systems in a Hilbert space of dimension . While contextuality can be
assessed on different degrees of freedom of the same particle, the violation of
local realism requires parties spatially separated.Comment: Submitted to Int. J. Theor. Phys. as part of the Collection IQSA22 -
Quantum Structures for Interdisciplinary Application
On the Fidelity Robustness of CHSH–Bell Inequality via Filtered Random States
No full textThe theorem developed by John Bell constituted the starting point of a revolution that translated a philosophical question about the nature of reality into the broad and intense field of research of the quantum information technologies. We focus on a system of two qubits prepared in a random, mixed state, and we study the typical behavior of their nonlocality via the CHSH–Bell inequality. Afterward, motivated by the necessity of accounting for inefficiency in the state preparation, we address to what extent states close enough to one with a high degree of nonclassicality can violate local realism with a previously chosen experimental setup
Lean Six Sigma Approach to Improve the Management of Patients Undergoing Laparoscopic Cholecystectomy
No full textLaparoscopic cholecystectomy (LC) is the gold standard technique for gallbladder diseases in both emergency and elective surgery. The incidence of the disease related to an increasingly elderly population coupled with the efficacy and safety of LC treatment resulted in an increase in the frequency of interventions without an increase in surgical mortality. For these reasons, managers implement strategies by which to standardize the process of patients undergoing LC. Specifically, the goal is to ensure, in accordance with the guidelines of the Italian Ministry of Health, a reduction in post-operative length of stay (LOS). In this study, a Lean Six Sigma (LSS) methodological approach was implemented to identify and subsequently investigate, through statistical analysis, the effect that corrective actions have had on the post-operative hospitalization for LC interventions performed in a University Hospital. The analysis of the process, which involved a sample of 478 patients, with an approach guided by the Define, Measure, Analyze, Improve, and Control (DMAIC) cycle, made it possible to reduce the post-operative LOS from an average of 6.67 to 4.44 days. The most significant reduction was obtained for the 60–69 age group, for whom the probability of using LC is higher than for younger people. The LSS offers a methodological rigor that has allowed us, as already known, to make significant improvements to the process, standardizing the result by limiting the variability and obtaining a total reduction of post-operative LOS of 67%
