Large reactivated earth flows in the northern Apennines (Italy): An overview
No full textThis paper proposes an overview on ancient earth flows and their reactivation mechanisms. All considerations made herein are the result of direct experience and observation of actual events which have occurred in the Northern Apennines from 1994 to 2006, when many large earth flows reactivated, 17 of which have been studied and monitored by the part of technical surveys of the Emilia-Romagna regional authority. Particular attention has been paid to the analysis of the evolution of landslides, acknowledging a typical, recurring succession of events that precede the failure of the slope. In general, the observation of past events has proved to be an useful mean for understanding which are the conditions and behaviours that usually lead to the reactivation of an ancient landslide body. © Springer-Verlag Berlin Heidelberg 2013
Il paesaggio geologico dei gessi triassici
No full textThis paper presents a virtual excursion “inside” the landscape of the Triassic Gypsum Formation and the upperSecchia Valley. It proposes an aerial view that, through different viewpoints, allows the observer to recogniseelements of the landscape that are difficult to see from the ground, such as the long faults shapingthe steep slopes and the largest landslides of the Emilia-Romagna Apennines. The broad bed of the Secchiariver flows in a straight course for 5.5 kilometres between towering rock-faces of white, pink and lightgray gypsum, rising up 200 metres in some point. Triassic Gypsum contains a number of different lithologies:gypsum, anhydrites, dolomite and quartzite, which form a distorted rock structure with fragments of layersthat present ruptures and folding. They were deposited during the Upper Triassic (215-200 million years ago)and therefore are the oldest rock outcrops in the Emilia-Romagna Apennines. The linear shape of the mainversants is interrupted by lateral valleys drawn by the tectonics, such as the Sologno and The Dorgola valleys.These numerous morphological features make this landscape unique within the Apennines. The steepgradients, coupled with instability brought about by karstic phenomena, make this a suggestive but highlyinhospitable area

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
