A multi-element psychosocial intervention for early psychosis (GET UP PIANO TRIAL) conducted in a catchment area of 10 million inhabitants: study protocol for a pragmatic cluster randomized controlled trial

Multi-element interventions for first-episode psychosis (FEP) are promising, but have mostly been conducted in non-epidemiologically representative samples, thereby raising the risk of underestimating the complexities involved in treating FEP in 'real-world' services

Analysis procedure of the low-cycle fatigue behaviour for structural elements and connections

A state-of-the-art research was performed in the scientific literature to assess the experimental procedures generally adopted by the scientific community for quasistatic testing of structural elements and connection. The main and widely used recommended protocols, particularly ECCS and ATC-24 recommendations, to which refers the large part of the researches performed on this topic, are described and analyzed. In order to overcome some limitations of the existing testing procedures, particularly in what regards the description of the unsymmetrical displacement histories experienced by real structural elements when subjected to an earthquake motion, acting simultaneously to vertical loads, a new testing procedure is proposed. Moreover some results of an experimental campaign on steel rack structural systems,carried out adopting the loading protocols of this new procedure, are presented

Attenuation Law and Local Hazard Evaluation

The paper refers to the attenuation of macroseisrnic intensity with epicentral distance. A new attenuation law is discussed, with particular reference to Italian conditions. For earthquakes of many Italian seismic regions, the new formula shows a much better fitting compared to traditional attenuation laws. The probabilistic approach to the evaluation of local hazard is then discussed under the Poissonian hypothesis for the occurrence process, with particular attention to the computational errors due to the (possible) non homogeneous spatial distribution of epicenters. A simple way to reduce such errors is suggested. Finally, the case in which the occurrence process does not comply with the Poissonian hypothesis is briefly discussed
