The Lame Rosse geosite (Northern Apennines, Italy): a glance at its formation processes
Full text linkThe COVID-19 pandemic has brought many Italians closer to the Nature, with a growing interest in trekking and related activities. To maintain this renewed interest in our natural environment, it will be important to further increase the awareness of visitors, also thanks to an accurate but, at the same time, simple and understandable scientific divulgation of the main features of most important geosites.
The “Lame Rosse” geosite (Fig. 1) has seen an incredible increase in visitors in recent years (the hashtag “#lamerosse” on Instagram indexes over a 16.5k posts in November 2021). Despite its fame, few geological information is available for the site. The aim of this note (derived from the BSc thesis of one of the authors, GP) is to provide a brief sedimentological and stratigraphic characterization of one of the most fascinating geosites of the Italian peninsula
Landscape influence on the development of the medieval city-state of Siena, Italy
No full textThis paper examines how the landscape has influenced the development of the medieval–early Renaissance city-state of Siena, Italy.
Siena is a hill-top town with a historic ~2 km2 wide core surrounded by ancient city walls. It still preserves the medieval urban plan and
Gothic architecture, and its inhabitants keep ancient traditions alive. It is built on Pliocene, loosely cemented, calcareous, marine,
porous sandstone that overlies impermeable marine calcareous silty clay. The town is limited on three sides by steep slopes indented
by secondary deep, narrow, small valleys. The forth side to the north is a gently sloping terrain along the hilltop leading to distant highlands.
This geomorphologic setting had been beneficial to the development of the town during mediaeval times because readily
defendable and, being far from wet, unhealthy, malaria-infested lowlands, it was crossed by a major medieval pilgrimage route (Via
Francigena) to Rome. However the hilltop location presented difficulties such as scarce availability of water and limited space to
expand.
Siena tried valiantly to adapt to the demand of expanding population and international markets. Two major underground aqueducts
were built for a total of about 25 km long tunnels, to bring water both to the centre of the walled town mainly for human consumption
and to a major fountain (fonte) complex at the base of the hill that was the major medieval industrial site. However, water was never
plentiful and became totally insufficient for the expanded mechanized industrialization of cloth-making that started in mid 14th century.
Siena could not compete with other towns, like the neighbouring Florence, endowed with fluvial hydraulic power.
Like other hill-towns Siena also had the problem of limited space for its growing population inside city walls. Within the city the space
was and still is maximized in two main ways. One is to level hilltops for constructions, such as the Cathedral, or cut terraces into the
easily quarried soft sandstone for buildings. The other is to build retaining walls in the upper parts of the secondary, indenting, narrow
valleys and partially filing their apex, as it was done during the last century to obtain the stadium and associated athletic facilities, or,
in the medieval times, to build the famous Palazzo Pubblico (Town Hall) and its antecedent, sloping semi-arcuate (Pecten-shell like)
public square

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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Alluvial fans at Cala Gonone (Sardinia), a fast developing touristic village: origins, hazards and potential risks
Full text linkThe study area of Cala Gonone in NE Sardinia (Italy) consists of a wide terraced re-entrance/valley crowned inland by carbonate hills and, near the coast bounded laterally and partly floored by thin basaltic lava lying over carbonate bedrock. In this re-entrance, several inland alluvial fans (500 m length by 700 m wide) have developed, and a local ~ 30 m high, about 10 m wide (thick), 400 m long scarp body-remnant of semi-consolidated alluvial fan deposits is exposed along the coast. The fans experience depositional events mostly developed during the late Pleistocene. They although nowadays dormant may be reactivated by major rainstorms during strong climate changes. In these last few decades, the touristic village of Cala Gonone has been rapidly expanding over the mid to lower parts of two coalescing alluvial fans (Stadium and Gustui) and along the coastal marine scarp edge (Palmasera alluvial fan system). The village thus may become exposed to natural hazards if extreme climatic conditions may re-occur. Moreover, rock falls and the instability of the costal scarp due to wave erosion may add addition hazards for habitations built near the scarp crest and visitors to the frontal replenished beach. As commonly occurring elsewhere since antiquity, the risk perception of such events is low because of the centennial, millennial of longer recurrence. Such perception does not negate the hazards but a long event recurrence may be accepted as a reasonable risk for the human’s activity. Nevertheless, serious consideration should be given to potential problems and plan and build for amelioration and defense. The evidence of what environmentally did and could still happen in the Cala Gonone and similar other area is in part clearly imprinted on the landscape: geology, geomorphology, and relative details in the stratigraphy and sedimentology of the deposits
