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
Il reimpiego a Roma nell’altomedioevo. Osservazioni dal complesso di San Paolo fuori le mura
No full textComparison between the various methods of re-employing materials in the
Saint Paul ’s Outside the Walls complex in Rome seems to highlight a difference
between the first half of the eighth century and the end of the same century. The first
phase, which is not very systematic and differentiated, differs from the much more
pronounced compositional uniformity of later buildings, which appears to be related
to the existence of real systems and societies of building-material recycling

No full textMinimal Forcemyography Human-Machine Interface for Hand Gesture Recognition
No full textThis study proposes a very simple Human-Machine Interface (HMI) to recognize six basic hand gestures. The device is equipped with only two forcemyography (FMG) sensors applied to specific forearm muscles and it is a scaled-down version of a previous one used for gesture recognition and control of exoskeletons and prostheses. Data collected from five healthy subjects were considered. A double-threshold segmentation technique of the two FMG signals allowed the extraction of features (i.e., mean, standard deviation, root mean square, area, slope) to recognize the hand gestures. Features were recalculated every 100 ms to provide real-time performance. Classification performance was evaluated using both Linear Discriminant Analysis (LDA) and a Linear-Support Vector Machine (L-SVM) classifier and applying 10-fold cross-validation. The mean accuracy across all subjects resulted in 93.07% and 96.14% using LDA and L-SVM, respectively. In summary, this research represents a further step forward in the field of FMG-based HMIs. The reduction of FMG sensors and optimization of data processing techniques, including segmentation and feature extraction, provide a more effective and easier-to-use HMI that can be employed in a variety of applications ranging from computer applications, games, prosthesis and exoskeleton control, etc
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
Intervento
No full textI drammatici eventi sismici susseguitisi a partire dal 24 agosto 2016 hanno sollecitato, con sempre maggiore urgenza, l’esigenza di confronti e dibattiti sulle tematiche più attinenti alle questioni sollevate da tali recenti vicende, comprese le modalità degli interventi post-sismici (dal restauro alla ricostruzione degli edifici, dalle questioni di metodo e dai criteri-guida alle tematiche legate ad aspetti strutturali e tecnici, a questioni organizzative ed economiche, all’analisi di casi di studio e di esperienze svolte in occasione di eventi sismici del passato, per ricavarne indicazioni quanto a metodi, strategie d’intervento e operatività)
