Collective memory and individual identity in society are increasingly losing their importance in contemporary cities. Both material and immaterial heritage has to become a strategic element by which a citizen can recognize himself in the spaces of his everyday life. In 2018, the municipality and universities of Barcelona provided a moment of international consideration - using the instrument of a hackaton. This reflection was focused on the infrastructural heritage represented by the “Rondas” – originally developed as a connective element while today being seen as separating structure.

Lung ultrasound is a useful tool for the assessment of patients with both acute and chronic heart failure, but the use of different image acquisition methods, inconsistent reporting of the technique employed and variable quantification of ‘B-lines,’ have all made it difficult to compare published reports. We therefore need to ensure that future studies utilizing lung ultrasound in the assessment of heart failure adopt a standardized approach to reporting the quantification of pulmonary congestion.

The information revolution is radically transforming the very foundation of the fossil city'. A 'virtual' macro-urbanism will intersect with an 'actual' micro-urbanism, physical and concrete, determining the form of the new urban environment. Within the binomial of macro- and micro- urbanism, urban morphology identifies an interesting socio-building scale that can serve as the basic strategy for sustainable city planning in the twenty-first century.

L’introduzione presenta i principali temi proposti nella rubrica focus di questo numero, dedicata ai più rilevanti problemi epistemologici e metodologici connessi all’utilizzo dei Big Data nella ricerca sociale. L’occasione per discutere di questi temi è stata offerta da un convegno nazionale promosso dalla sezione di Metodologia dell’Associazione Italiana di Sociologia dal titolo «Big Data, Big Challenges» che si è tenuto il 28 aprile 2017, presso l’Università degli Studi di Milano-Bicocca.
