3D limit analysis of Hall I in the Baths of Diocletian
In Roman Baths the Romans employed groin vaults of great dimen-sions, with maximum span more than 20 m; simple tools of structural analysis of ancient wide span vaulted halls are still lacking, due to ge-ometrical and material complexity. In this paper we study the collapse behavior, under horizontal static action, of a corner cross vault of the Baths of Diocletian in Rome (Hall I). In the present modeling, mason-ry is discretized as a system of interacting rigid bodies in no-tension and frictional contact. The computational code consists in a linear pro-gramming approach which makes use of a series of optimization pack-ages via lower and upper bound techniques of limit analysis. One more task of the proposed problem consists in a suitable description of the overall 3D geometry, here afforded with a specific pre-processing ap-proach
The 'Terre dei vulcani' case: Technology management in a cultural tourism destination
Case study on the choice and management of information technology in a tourism destination, with a web application for the simulation of the result
Sicurezza vs conservazione?
"⋯seismic restoration of historical centers has to include all aspects regarding both safety and preservation⋯" (A. Giuffrè). The term safety can be misleading for common people: safety is not the same as certainty, it is a probabilistic concept that implies the evaluation of the probability of failure; it could be defined failure assessment. This last definition might be understandable as a more realistic message to a broader audience. Rebuild as it was and where it was? Repair damage as in the past? Strengthen as before? The wisdom, the serious damages occurred, and the current guidelines suggest different solutions. The main task of all of us, is to find them
Tuscany/Toscana
Series 17/6 is devoted to the recordings of Italian prisoners of war, made by linguist Karl von Ettmayer in the Upper Austrian camps of Mauthausen and Marchtrenk. The recordings are accompanied by detailed written documentation (the so-called protocols), which include transcriptions and German translations. Ettmayer, however, seems to have written these protocols prior to the actual recording process, since those extant do not correspond to the numbers of the recordings. Such “errors” are rather unique and asked for a lot of detective work in order to assign them to the respective recorded contents. Thanks to the fruitful cooperation with Serenella Baggio (University of Trento) and her team, it has been possible to provide detailed linguistic analyses of the recordings. The corpus is a quarry for dialectologists, and the language samples chosen – three different tales in a rural setting – were analysed not only with regard to pronunciation, but also to dissemination and popularity. The in-depth characterisation of the respective dialects clearly shows the marked differences between the various regions, which also reflects the historico-political situation

CSR and management control integration. Evidence from an employee welfare plan implementation
Relatively little research has addressed questions on how companies integrate corporate social responsibility (CSR) and management control, and this study attempts to respond to recent calls for further investigation. Taking the perspective, advanced in the extant literature, that CSR can be regarded as a form of management control, the study has the objective to show how a socially responsible initiative, such as the implementation of an employee welfare plan undertaken by a SME, can address control issues. In particular, the company has designed the employee welfare plan as an incentive system. The study adopts an interventionist research (IVR) approach to accomplish with the research objective, and the results of the interventionist case study are interpreted based on the Merchant and Van der Stede object-of-control framework. In particular, results indicate that the implementation of the welfare plan has enabled the application of different types of control and provided incentive-related benefits, suggesting the potential impact of CSR as a management control device.Relatively little research has addressed questions on how companies integrate corporate social responsibility (CSR) and management control, and this study attempts to respond to recent calls for further investigation.

Integrated Modeling of Minerva Medica to Identify the Dynamic Effects of Rail-Traffic Vibrations
A comprehensive study was carried out to integrate information from different sources and evaluate the effects of induced vibrations on a temple. Historical analysis was fundamental to interpreting the evolution of the construction and defining the HBIM. Experimental data were implemented in the FEM of the site, including the temple, its foundations, and the soil stratifications. Sensitivity analysis was carried out to identify the most influential parameters, which were calibrated to reduce error with the experimental frequencies. The FEM was further optimized with the Douglas–Reid method, considering, simultaneously, modal frequencies and deformations. Two different nonlinear dynamic analyses were performed; one analysis studied the effect on the temple of the dynamically moving load of the tram, and the other analysis studied the response of the temple to three-dimensional accelerations applied at the base. The drawbacks of each simulation were identified by comparing the numerical and experimental results
model updating of a masonry historical church based on operational modal analysis: the case study of San Filippo Neri in Macerata
The paper describes the approach followed in the characterization of the structural behavior of the historical masonry church of San Filippo Neri in Macerata, severely damaged and condemned after the Central Italy Earthquake occurred in October 2016. The case study of San Filippo Neri is particularly interesting: first for the historical and artistic importance of the churchfurthermorefor the evidences of recurrent structural damage. The laboratory of Proof and Research on Structures and Materials of Roma Tre University carried out an extensive onsite testing campaign - including geometric survey, flat-jack test and ambient vibration test - in order to investigate the state of the building. Operational modal analysis was used to assess the dynamic behavior of the church; the results of the testing campaign were interpreted and correlated with an accurate finite element model of the construction. The numerical model was finally tuned up based on the experimental results in order to match the dynamic behavior. The aim of the research is to set the first steps for an integrated approach able to fit and combine the resultsfrom experimental onsite testing and numerical modelling
