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
Elaborazioni GIS 3D per la lettura del territorio:un esempio per la Riserva Naturale delle Salse di Nirano(Appennino Modenese)
No full textThe Regional Natural Reserve of Salse di Nirano is located in the low hill territory of the Modena Apennine, about 30 kilometers from Modena. The Reserve, visited yearly by about 50,000 people,was established in 1982 and its characteristic element are the so-called “Salse”. They are emissions of cold mud up to the surface through faults and fractures, due to the ascent of salty andmuddy water mixed mainly with gaseous (methane) and secondly with fluid hydrocarbons (petroleum veils). Depending on the density of the mud, at the surface it can be observed cones or pools at ground level. The products described below have been made for the promotion and the enhancement of the Reserve. The first consists of a three dimensional image, obtained from the 5 m DTM of the Emilia Romagna Region texturized with the Agea 2008 Digital Orthophoto, in order to let even non-experts to appreciate the particular morphology of the valley where the Salse are located and of the surrounding badlands. The image was published in the Tourist-EnvironmentalMap of the Regional Natural Reserve of Salse di Nirano characterized also by a Geotourist map that combines the most evident geological and geomorphological aspects with basic tourist information. In addition, it was made a short video based on scenes of a virtual flight on the territory of the Reserve (fly-through) obtained by using ESRI ArcScene, properly assembled and enriched with descriptive and didactical elements that highlight the mainly geomorphologicalaspects of the area. Everything has been completed with the toponyms and some pictures of the most distinctive or interesting subjects (the mud ejection points, the badlands, the Reserve’sfacilities, etc..). The video will be available at the Visitor Centre, at the Ecomuseum headquarters and on the Internet with the aim to "accompany" visitors in an engaging virtual guided tour to theprotected area, facilitating the understanding of the landscape
Digital documentation and monitoring hub in climate-sensitive territories: The albenga case study (san clemente site)
Full text linkThis paper will go into further detail on pressures and policies faced by the archaeological site of San Clemente's caretakers, that affect the sites preservation. Including the protection of the riverbed along the fragile coast line represented by the masonry portion of the thermal bath's foundation which is directly in contact with the water. Being the destiny of the site to be gradually eroded by flooding, digital documentation can play a significant role in documenting the sites changes over time allowing for easy analysis of newly revealed elements. As in the case of the documentation of the viewable openings through the thermal masonry-pipeline during the last surveying campaign this paper will discuss the experimentation of data management through Virtual Hub. Through which past sequences of data can be made accessible to anyone who must operate on the site, and to document the state of affairs of the archaeological complex over the last few years
Between history, work and passion: medieval castle, mud volcanoes and Ferrari
Full text linkThis field trip guide organized in the framework of the Goldschmidt Conference 2013, held in Florence from
August 25 to 30, 2013, is here presented.
The two-days field trip, shows some of the many geological, naturalistic and cultural features in the Fiorano
area (Modena), in which history, geology and passion for Ferrari come together in a perfect marriage.
The first excursion day is dedicated to visit the Natural Reserve of Salse di Nirano, where the mud volcanoes,
produced by the cold mud, salt water and hydrocarbons - mainly methane- can be observed.
The second day is devoted to visit the Ferrari Museum and goes on at the Spezzano Castle, hosting the Ceramics
Museum. Clays are, in fact, abundant in the hilly margin, where they form badlands, characteristic narrow crests
washed out by running waters. In the Castle there is also a Balsamic Vinegar producing Consortium, it’s a peculiar
and typical product of Modena province. The itinerary ends with the tour to Enzo Ferrari’s Birthplace at Modena
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Tourist valorisation of the Natural Riserve of the Salse di Nirano through a multimedia gallery on CD-Rom
No full texthe natural reserve of Salse di Nirano custodies the widest “salse” complex of the region and one of the most important in Italy and in Europe. The Salse di Nirano was the first natural reserve to be recognized by the Emilia-Romagna region, in 1982. Besides the peculiar geological phenomenon this Natural Reserve represents an important ecosystem. Year 2007 is the 25th anniversary of the Reserve and, for this occasion, a digital multimedia gallery, in a CD-Rom format, has been realized.The aim of the CD-Rom was to valorise the Natural Reserve of the Salse through detailed scientific studies undertaken on all naturalistic and anthropic aspects of the Reserve. The CD-Rom language is Italian, but also a short English version is present.The output of the work was a renewed and up-to-date research organized in one CD-Rom that can be browsed like a web page. A brief introduction is followed by the description of the Reserve. The core of the CD-Rom is represented by the scientific aspects which include: the details on the Salse phenomenon, the geology and the geomorphology of the area, its flora and vegetation, its fauna, its fossils and its climate. Each scientific chapter is an autonomous page with a central text and side pictures that can be enlarged by directly clicking on them or by clicking on their respective hyperlink in the text. Words that are too specific of each scientific jargon have been left as they are in the text, but an hyperlink on them may guide the reader to better understand their meaning thanks to pop-up windows.A part of the CD-Rom is dedicated to tourist aspects. The core of it is represented by the Geo-tourist map which gives a complete and accurate overview of all the current attractions present. This map, like all the other maps present in the CD-Rom, can be also viewed and downloaded as PDF file.The last part is a multimedia gallery that groups sound recordings, short movies and photos capturing glimpses of the everyday’s natural life of the Reserve, plus a virtual flight. A bibliographical gallery contains references and PDF files of the main scientific papers on the Reserve area
