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
Method for Managing the Storage of Elements Positioned on Collecting Members and Management System for Elements Positioned on Collecting Members
No full textMethod for managing the storage of elements positioned on collecting members in a storage area (SA), said method comprising: providing a plurality of collecting members (TR) to be positioned in said storage area (SA); positioning one or more elements (E) on each one of said collecting members (TR), each element being associated with at least one of a first parameter (PI), representative of structural and/or geometric characteristics of said element, and a second parameter (P2), representative of a time interval of possible use of said element; storing an association between each one of said collecting members (TR) and the element(s) (E) positioned on said collecting member (TR); mounting at least two RFID tags (T1-T4) on each collecting member (TR), each RFID tag (T1-T4) being associated with an identification code (TID1-TID4), each RFID tag (T1-T4) being mounted on said collecting member in a respective determined position; for each collecting member (TR), identifying one or more respective geometric quantities (D1-D6) correlated with the determined positions of said RFID tags (T1-T4), and storing a real value (RV1-RV6) for each one of said geometric quantities (D1-D6); providing at least one RFID reading system (100) in said storage area (SA), a respective reading area (RA) being associated with said RFID reading system (100); when a given collecting member (TR') of said collecting members (TR) is in said respective reading area (RA), reading, by means of said RFID reading system (100), the identification code (TID1'-TID4') of the RFID tags (Τ1'- T4') mounted on said given collecting member (TR'); determining a recognition code (XID') of said given collecting member (TR') as a function of one or more identification codes (TID1'-TID4') of said RFID tags (Τ1'- T4'); determining an estimated position (EP1-EP4) of each one of the RFID tags (T1'-T4') of said given collecting member (TR'); determining, as a function of the estimated position (EP1-EP4) of each one of the RFID tags (T1'-T4') of said given collecting member (TR'), an estimated value (EV1- EV6) for said geometric quantities (D1-D6); comparing said estimated value (EV1-EV6) with said real value (RV1-RV6), thereby obtaining a corresponding result (Y); determining, as a function of the estimated position (EP1-EP4) of the RFID tags (T1'-T4') of said given collecting member (TR') and said result (Y), a position (XP) of said given collecting member (TR'); storing the position (XP) of said given collecting member (TR') in association with said recognition code (XID) of said given collecting member (TR'); upon reception of a request signal (REQ) from a working station (200) adapted to work on one or more of said elements (E), selecting, as a function of the at least one of said first parameter (PI) and said second parameter (P2) associated with each one of said elements (E), at least one (Ex) of the elements (E); identifying, as a function of said at least one selected element (Ex) and one of said stored associations, the collecting member (TRx) on which said at least one selected element (Ex) is positioned; generating a response signal (RESP), containing indications representative of the position (XP) of said identified collecting member (TRx) on which said at least one selected element (Ex) is positioned. A management system for elements positioned on collecting members is also described
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
UWB Real-Time Location Systems for Smart Factory: Augmentation Methods and Experiments
No full textIn Industry 4.0, real-time location systems are emerging as a key technology to improve the efficiency of industrial processes, as they allow to track any assets or material movement and collect data on their usage. Ultra Wideband (UWB) systems offer unrivaled localization accuracy, but they call for augmentation strategies in environments with complex propagation conditions such as plants or factories with high density of scattering objects and obstructions. In this paper, we focus on Bayesian filtering techniques to counterbalance the detrimental effects induced by non line of sight and dense multipath in a smart factory scenario. We first conduct a set of experimental tests with commercial devices in an industrial facility of Pirelli Tyre S.p.A. located in Milan, Italy. We then use the collected data to design and test augmentation algorithms based on Extended Kalman Filter (EKF) and Particle Filter (PF), fusing Time Difference of Arrival (TDoA) and Angle of Arrival (AoA) signals. Experimental results show that, despite the harsh environment, accurate localization is possible by fusion of hybrid measurements and integration of prior information on the target dynamics and the industrial propagation environment
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
