Seasonal effects in the groundwater regime of unsaturated slopes
No full textLandslides in partially saturated pyroclastic slopes are strongly linked to rainwater infiltration, which is the main factor responsible for pore pressure and shear strength variations in shallow subsoil. Monitoring of the groundwater regime allows the most critical period for slope stability to be identified and the rela-tionship between critical pore pressure and rainfall to be explored. This paper de-scribes the monitoring of an unsaturated pyroclastic slope instrumented at Monteforte Irpino in southern Italy (Pirone et al., 2010), where suction and volu-metric water content measured at different depths were collected from 2006 to 2011. Using this database, typical aspects of the groundwater regime are de-scribed. The maximum water content is observed to be significantly lower than the saturated value measured in the laboratory (Nicotera et al., 2010). This condition affects permeability attained in situ during the wet period of the year and hence in-filtration

Diseguaglianze digitali: l’età nel modello di accesso e uso delle ICT in Italia
No full textIl saggio presenta prima un quadro statistico descrittivo delle differenze di accesso e delle capacità d’uso del computer e di internet tra i diversi gruppi d’età in Italia. Successivamente saranno presentati e discussi i risultati di una survey relativa ai fattori che incidono sull’uso del computer tra le persone adulte e anziane (con 50 anni ed oltre). A partire da queste analisi, in conclusione, saranno discusse alcune tesi relative alla riproduzione delle diseguaglianze digitali, con particolare attenzione all’incidenza del fattore età
