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
Application of the compurised cartography to the territory management: the geomorphological map of palaeolandslides in the Velino River Valley
No full textThe geomorphological cartography explained in this work is the result of a process of synthesis resulting from detailed geological and geomorphological and hydrogeological researches and from numerous land surveys carried out during the past ten years. The choice of the study area can be explained by the presence of important and complex phenomena involving the upper course of the Velino river, such as palaeo-landslides, mass-movements and debris flows, subsidence phenomena, etc. In particular, these phenomena involve several towns (Posta, Micigliano, Sigillo, Villa Camponeschi), as well as a fundamental route (State Road 4), following the ancient consular road, named Salaria, roman in age.
The informations deriving from the land surveys has been integrated and controlled by photo-interpretation (related at 1982 and 2000 aero-photographs). The result has been implemented by the 2006 cartography, which was obtained from the ortho-rectified images, subject to a “spreading” over the digital model of the terrain that was obtained from the regional topographical cartography at a scale of 1:10,000, promoted by the Lazio Region. Even if they have well-known limits of representation that derive from the approximate restoration of the basic regional maps that were realised in the 1980s, the latter represent a very up-to-date control instrument, depending on a critical analysis of the information.
All the data have been computerised by exploiting the tools made available by the ESRI platform, through the development of an innovative logical pattern for the geomorphology, since the aforesaid data were treated by considering forms, processes and deposits on the basis of the prevailing morphogenetic agent. In this way, the problems deriving from the contiguity and superimposition of several polygonal forms in logical contrast and topological conflict have been overcome.
Hopefully, several representational limits will be overcome once the set-up valid for the published printing has been made ready, since the instruments currently available have several technical limitations in the raster process and, in spite of the information present is correct, it does not yet respect several qualitative standards typical of Italian graphic representation.
Several graphic improvements typical of the Italian publishing language and cartographic tradition will be the topic of the subsequent phase.
Despite Italian tradition imposes extreme attention on the graphic aspect, it is very important to note that the territorial computer-related systems facilitate an analysis of the coverings, depending on the substrate on which they are imposed, and make it possible to define a model according to which the forms, processes and deposits evolve over time, infact the whole upper valley of the Velino river is annually subjected to deep changes due to the high energy of relief and extreme weather conditions: knowledge and proper analysis of these phenomena can contribute significantly to the right land management, giving due importance to the prevention and the screening to be daily carried out
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
