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
A highly stretchable artificial sensitive skin using EIT
No full textCurrent sensing technologies are very challenging to implement over 3D sur- faces and present wires within the active sensing area, limiting their overall deformation and creat- ing fragility. These critical limitations hinder their integration for arti cial skin purposes, while a soft and low-cost solution is needed, especially on high-deformable areas
A Quantitative Evaluation of Drive Patterns in Electrical Impedance Tomography
No full textAbstract. Electrical Impedance Tomography (EIT) is a method used to display, through an image, the conductivity distribution inside a domain by using measurements taken from electrodes placed at its periphery. This paper presents our prototype of a stretchable touch sensor, which is based on the EIT method. We then test its performance by comparing voltage data acquired from testing with two different materials, using the performance parameters Signal- to-Noise Ratio (SNR), Boundary Voltage Changes (BVC) and Singular Value Decomposition (SVD). The paper contributes to the literature by demonstrating that, depending on the present stimuli position over the conductive domain, the selection of electrodes on which current injection and voltage reading are performed, can be chosen dynamically resulting in an improved quality of the reconstructed image and system performance
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
Cupole murarie tra XV e XVI secolo. Programmi, saperi costruttivi e restauri attraverso la Campania
No full textThe investigation about historical construction processes involves a research field whose effects on contemporary strategies for
conservation and risk prevention are particularly relevant in seismic contexts. Taking this into account, this special monographic
issue gathers thirty two contributions, illustrating the methodology applied to a research project granted by the University of Naples
Federico II (2017-2020) concerning Renaissance domes – constructively complex and vulnerable – considered as visual poles
emerging in the urban historic landscape of Campania. The research aims at experimenting an integrated knowledge approach
which combines traditional with innovative strategies for the comprehension of visible/ invisible structures. Crucial issues such as
the overlapping of inner and outer surfaces, the difficult inspection and the inaccessibility due to big dimensions and heights from
the ground of the domes are addressed. Finally, the transposition of the research outcomes into digitally accessible tools aims at
reaching a broader cultural and inclusive awareness raising on built heritage historical and constructive values.
L'indagine sui processi costruttivi relativi al patrimonio storico coinvolge un ambito di ricerca i cui effetti sulle strategie conservative
e di prevenzione dal rischio sono particolarmente rilevanti, soprattutto entro un contesto sismico. Tenendo conto di tali specificità,
questo numero monografico raccoglie trentadue contributi nei quali si illustra una parte degli esiti della metodologia applicata
nell'ambito del progetto di ricerca finanziato dall'Università degli Studi di Napoli Federico II (2017-2020) inerente allo studio
delle cupole rinascimentali – costruttivamente complesse e vulnerabili – considerate quali poli visuali emergenti nel paesaggio
storico urbano della Campania. In particolare, la ricerca è volta a sperimentare un approccio integrato di conoscenza che
intreccia strategie tradizionali e innovative ai fini della comprensione di componenti visibili e invisibili del sistema strutturale.
Entro tale prospettiva di indagine vengono affrontate problematiche intrinseche a sistemi costruttivi di questo tipo, relative alla
sovrapposizione tra superfici interne ed esterne ovvero alla difficile ispezione e alla frequente inaccessibilità, imputabili alle
dimensioni o alla notevole elevazione dal suolo delle cupole. Quale obiettivo precipuo, la trasposizione dei risultati della ricerca
entro strumenti digitali accessibili mira, infine, ad ottenere un impatto positivo sulla diffusione di una consapevolezza culturale,
quanto più ampia e inclusiva, dei valori costruttivi storici del patrimonio costruito
