Purpose – The purpose of this paper is to propose a business process reengineering (BPR) approach to a public administration of Italy, to first assess the efficiency of the administration, then to redesign its internal processes, to improve the current performance. Design/methodology/approach – A detailed mapping of the AS IS processes of the public administration was initially carried out, together with the collection of the relevant data. Then, a simulation model was designed to support the BPR approach. In particular, the model was exploited to assess the performance of the AS IS scenario of the organization, then to investigate numerous TO BE process configurations and evaluate the achievable performance improvements. Findings – From the study, it emerged that the current efficiency level of the public administration examined has potentials to be significantly improved. For instance, by maintaining its current workforce, the public administration could consider the opportunity of providing additional services to the citizens or to serve citizens from the neighbouring municipalities. Otherwise, the organization could consider a reorganization and reduction of its current workforce, at the same time keeping the service level to its citizens almost unchanged. Research limitations/implications – Results of this study cannot be fully generalized, since the whole analysis is grounded on specific public administration. Moreover, although the simulation outcomes of the TO BE processes show interesting improvements compared to the AS IS scenario, the TO BE configurations were not (yet) implemented in practice. Therefore, the results provided should be confirmed in future research activities. Practical implications – The case study allowed deriving some useful guidelines to improve the efficiency of the public administration examined, as well as to identify some TO BE configurations that could be implemented in practice. Originality/value – Scientific literature includes a limited number of studies that evaluate the efficiency of public organizations in real contexts. Moreover, no studies target public administrations in Italy. Therefore, this case study represents an interesting addition to the literature.

The Milos volcanic field includes a wellexposed volcaniclastic succession which records a long history of submarine explosive volcanism. The Bombarda volcano, a rhyolitic monogenetic center, erupted -1.7 Ma at a depth <200 m below sea level. The aphyric products are represented by a volcaniclastic apron (up to 50 m thick) and a lava dome. The apron is composed of pale gray juvenile fragments and accessory lithic clasts ranging from ash to blocks. The juvenile clasts are highly vesicular to non-vesicular; the vesicles are dominantly tube vesicles. The volcaniclastic apron is made up of three facies: massive to normally graded pumice-lithic breccia, stratified pumice-lithic breccia, and laminated ash with pumice blocks. We interpret the apron beds to be the result of water-supported, volcaniclastic mass-flow emplacement, derived directly 1u the collapse of a smallvolume, subaqueous eruption column and from syneruptive, down-slope resedimentation of volcaniclastic debris. During this eruptive phase, the activity could have involved a complex combination of phreatomagmatic explosions and minor submarine effusion. The lava dome, emplaced later in the source area, is made up of flowbanded lava and separated from the apron by an obsidian carapace a few meters thick. The near-vertical orientation of the carapace suggests that the dome was intruded within the apron. Remobilization of pyroclastic debris could have been triggered by seismic activity and the lava dome emplacement.
