Isoerosivity and erosion risk map for Sicily

This paper reviews simplified methods for evaluating the rainfall erosivity index and proposes two relationships for estimating the annual value of Wischmeiers rainfall erosivity index at sites equipped with recording and non-recording raingauges. For the Sicilian region, the FAO index was also found to represent the erosion risk. A regional relationship to estimate the standard deviation of the annual erosivity index is proposed. The isoerosivity map is plotted by using 41 values of the rainfall erosivity index calculated by Wischmeiers procedure and 128 values estimated according to a relationship proposed by the authors. Finally, for each of 169 sites, an erosion risk index is calculated and an erosion risk map is plotted.

Sediment delivery processes and the spatial distribution of caesium-137 in a small Sicilian basin

The sediment delivery processes occurring in a small Sicilian basin are modelled using the spatially distributed SEDD model recently proposed by Ferro and Minacapilli. The model is applied by using soil data (grain-size distribution, organic matter content, etc.) of 129 samples uniformly distributed over the study area and compiling the available information (topographic map, soil data, etc.) into a Geographical Information System. Finally, the predictive capability of the distributed sediment delivery approach is tested experimentally using the caesium-137 measurement technique. The comparison between calculated sediment yield and the corresponding measured caesium-137 loss is used to validate the SEDD model at the scale of both the single morphological unit and the entire basin.

From the manuscript to YouTube Liturgical and paraliturgical chants on the Web

Over the last few years, ethnomusicological research in Italy has, just like elsewhere, increasingly become the subject of collective discussion and reflection by scholars of the sector. This has resulted from a sharp change in methodological approach, which was also a consequence of the mutation that interested the very way in which music is written and the benefits deriving from this, including the one that – conventionally – we have always defined as ‘traditional’. A crucial effect of this change came with the advent of the Internet and particularly of some virtual spaces dedicated to music. The article first focuses on the phenomenon of the documentation and the on-line fruition of traditional music, especially liturgical and paraliturgical chants. Thanks to some examples, the paper also offers some reflections on the possibility of considering these virtual fieldworks as new areas of research in ethnomusicology.
