No full textLandslides in stiff clay slopes along the Adriatic coast (Central Italy)
No full textThe slopes below the town of Petacciato are part of a landslide basin where several landslides, of different depth, are located. The study aims at investigating the overall sliding mechanism, focusing on both the recognition of the most active bodies and the interpretation of their interaction during the reactivation events. The combined analysis of geomorphic data, field investigation results and limit equilibrium back analyses results in the understanding that only the inland portion of the deep paleo-landslide has been repeatedly reactivated during the 20th century, followed by the formation of a new shear band at the toe of the slope, about the coastline. The reactivation starts with the mobilization of an intermediate depth body, lying upslope in the western portion of the basin, whose movement causes the mobilization of a deep body at the toe of the slope which in turn activates the inland portion of the deep paleo-landslide

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
Geostructural survey and stability analysis of the calcareous cliff of Vieste (Gargano-Southern Italy)
No full textSome years ago several large collapses of the fractured calcareous rocks in the Vieste cliff occurred. Due to both the structural condition of the rock mass and the tectonic alignment of this part of south east Italy, the bedding is variable. Where the cliff is oriented NE (Iudeca street) the bedding planes are almost dipslope with an inclination lower than the slope angle, whereas in the Punta San Francesco they are counterslope. The intersection of the joints results in the formation of prismatic blocks of various sizes, which are frequently in a condition of incipient fall. A combined geological and structural survey of the cliff was undertaken and distinct element analyses performed to evaluate the evolution of the stress-strain behaviour of the cliff. © Springer-Verlag 2008
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
