Laughing Is Not an Exception! An Italian Perspective on the Autonomous Protection of Parodies Beyond Elaboration
Full text linkThis paper analyses the legal regime of parodistic work from an Italian and European copyright law perspective. Taking into consideration that the Italian Copyright Act does not contain any specific parody exception, the author maintains that parodistic works cannot fall within the scope of the quotation and criticism exception. Based on the fact that, as is well known, EU copyright law does not allow Member States and national courts to apply a general “fair use” doctrine to support the lawfulness of using another’s work for parodistic purposes, it is argued that the use of a previous work to create a new parodistic work falls beyond the scope of copyright protection, and that the creation and commercialisation of a parodistic work cannot be prohibited by the author of the parodied work, since the former does not amount to an elaboration of the latter
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
Antiresonances of Cut and Cracked Bars: Experimental Results
No full textAn experimental study was carried out to evaluate the possibility of using the antiresonances of flexural vibrating bars to detect cracks or cuts. Two groups of bars, cracked bars and cut bars, were considered. The flexural vibrations of each free-free constrained bar, excited using the impulsive technique, were experimentally analysed measuring the accelerations in each excitation point. The distribution of the first antiresonance frequencies vs the position of impact/measurement points was then plotted, and the correlation with the corresponding n-th mode shape was found. The defect position corresponded to the areas in the plot where this distribution is discontinuous and it is determined with an uncertainty of ±2% of the bar length. These results confirm that, in laboratory experiments, the flexural behaviour of cut bars is similar to that of cracked ones. From a diagnostic point of view, this method can be used together with other methods that use resonances to detect defects
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
Experimental modal analysis of two-wheeled vehicles. Prediction of the response to road unevenness
No full textThe experimental study of the vibrations of two-wheeled vehicles gives useful results when it is carried out exciting the whole vehicle through the wheels. Modal analysis techniques make it possible to identify both in-plane modes, which influence comfort, and out-of-plane modes, which influence stability and handling. In the paper some results in terms of natural frequencies, damping coefficients and modal shapes are presented. The possibility of predicting the comfort on the road making use of the transfer functions measured in laboratory test is highlighted
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
