Tensions and Paradoxes of Scaling Up : A Critical Reflection on Physical Activity Promotion
2022
Background: Achieving system-level, sustainable ‘scale-up’ of interventions is the epitome of successful translation of evidence-based approaches in population health. In physical activity promotion, few evidence-based interventions reach implementation at scale or become embedded within systems for sustainable health impact. This is despite the vast published literature describing efficacy studies of small-scale physical activity interventions. Research into physical activity scale-up (through case-study analysis; evaluations of scale-up processes in implementation trials; and mapping the processes, strategies, and principles for scale-up) has identified barriers and facilitato…
Pseudospectrum of Reissner-Nordström black holes: Quasinormal mode instability and universality
2021
Black hole spectroscopy is a powerful tool to probe the Kerr nature of astrophysical compact objects and their environment. The observation of multiple ringdown modes in gravitational waveforms could soon lead to high-precision gravitational spectroscopy, so it is critical to understand if the quasinormal mode spectrum is stable against perturbations. It was recently shown that the pseudospectrum can shed light on the spectral stability of black hole quasinormal modes. We study the pseudospectrum of Reissner-Nordstr\"om spacetimes and we find a spectral instability of scalar and gravitoelectric quasinormal modes in subextremal and extremal black holes, extending similar findings for the Sch…

Valutazione della Vulnerabilità a Scala Territoriale: Il Caso Studio di Caltabellotta (AG)
2017
I recenti studi nell’ambito della valutazione del rischio sismico a scala urbana-territoriale hanno fatto emergere la necessità di coniugare tecniche speditive e metodologie accurate, sia per il rilievo del costruito che per l’individuazione delle criticità e l’analisi strutturale. In quest’ambito, le schede CARTIS (schede di primo livello per la caratterizzazione tipologico-strutturale dei comparti urbani costituiti da edifici ordinari) rappresentano uno strumento in grado di fornire i dati necessari per la valutazione della vulnerabilità sismica con metodi tipologico-osservazionali. Nel presente lavoro si illustrano le metodologie adottate per la caratterizzazione costruttiva, il rilievo …
