AbstractThe healthcare is often considered one of the sectors most prone to corruption, and transparency policies have been proposed in several countries to fight bribery and corruption. Indeed, the transparency of public bodies potentially plays a relevant role in preventing misbehaviour and favouring accountability. This study contributes to a broader understanding of the role of transparency in the healthcare sector using Italy as a case study. For this purpose, we first built a composite indicator to assess the differences in transparency, performance, and integrity between Italian local health authorities (LHAs) retrieving the administrative data available on their websites. Then, we used both non-parametric method and multivariate regression to explore the relationship between the performance of different expenditure functions (total production costs, administrative costs, and medical and non-medical-related service costs) at the LHA level and the transparency index. Our results show a wide difference in transparency, performance, and integrity among LHAs that does not always follow the classic north–south divide in Italy. In addition, we find results consistent with the idea that transparency is generally associated with a better capability of LHAs in the containment of healthcare expenditure while imposing larger administrative burdens. Overall, reforms promoting transparency impose administrative costs, which policymakers should bear in mind to develop less burdensome transparency measures, as they might not be a 'free lunch'.

The present paper describes the main features and an application to a real Nuclear Power Plant (NPP) of an Integrated Software Environment (in the following referred to as "platform") developed at University of Pisa (UNIPI) to perform Pressurized Thermal Shock (PTS) analysis. The platform is written in Java for the portability and it implements all the steps foreseen in the methodology developed at UNIPI for the deterministic analysis of PTS scenarios. The methodology starts with the thermal hydraulic analysis of the NPP with a system code (such as Relap5‐3D and Cathare2), during a selected transient scenario. The results so obtained are then processed to provide boundary conditions for the next step, that is, a CFD calculation. Once the system pressure and the RPV wall temperature are known, the stresses inside the RPV wall can be calculated by mean a Finite Element (FE) code. The last step of the methodology is the Fracture Mechanics (FM) analysis, using weight functions, aimed at evaluating the stress intensity factor (KI) at crack tip to be compared with the critical stress intensity factor KIc. The platform automates all these steps foreseen in the methodology once the user specifies a number of boundary conditions at the beginning of the simulation.
