GREENWAYS AND DISUSED RAILWAYS. THE CASE OF SULCIS-IGLESIENTE (SARDINIA, ITALY)
No full textThe greenways meet the current needs for sustainable mobility, being environmentally friendly, alternative and complementary to motorized mobility. The disused railway tracks are well-suited for conversion into greenways, both for their general construction (low slopes, large radius bends, etc.) and for the presence of related structures (stations, railway tolls) used for services associated with the path itself. In the island of Sardinia (Western Mediterranean Sea), there are many disused railway lines, which run through the territory in areas that are of particular interest from the perspective of environment and tourism. In this contribution, we will focus on the Sulcis Iglesiente, an historic region of Southwestern Sardinia, where in addition to disused state or regional railways, there are several mining railroads that, built in the years of mining boom in this part of the island (early 1900’s), are now totally abandoned. Mining railroads keep the same features of other types of railway construction, but they run through landscapes of a special environmental value, enriched by the evidences of past industrial activities that have historically been fundamental for the social-economic growth of this territory. This paper concerns the design of a network of equipped greenways for the Sulcis Iglesiente, separate from the ordinary roads, but integrated with it, serving both local and tourists, offering to the users an exceptional historical and environmental context. This is an ongoing process, sponsored by the Geo-mineral Historic and Environmental Park of Sardinia, involving both public administrations and the local communities. On the whole, the Park regards the old railway structures as a driving force for the enhancement of its patrimony of industrial archaeology

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
