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

Battery pack intelligent management system and battery pack monitoring diagnostic device
No full textThe utility model relates to a battery pack group intelligent management system and a battery pack monitoring and diagnosing device. The battery pack group intelligent management system comprises a plurality of battery pack monitoring and diagnosing devices, a battery replacement control device, a charging control device, a battery pack transfer tool and a remote management platform. The battery pack monitoring and diagnosing device is used for sampling the use state data of the battery pack and the driving data of the electric vehicle according to a preset frequency; the battery replacement control device is arranged in the battery replacement control chamber and is used for providing battery pack data in the battery replacement station controlled by the battery replacement control chamber; the charging control device is arranged in the charging control chamber and is used for providing battery pack data in the charging field controlled by the charging control chamber; and the remote management platform is in signal connection with each battery pack diagnosis device, each battery replacement control device and each charging control device and is used for performing intelligent management of charging and battery replacement on the battery packs. According to the utility model, intelligent management of the battery pack group in a charging and replacing separation mode is realized
Battery pack replacement decision-making method, device and system in charging and replacement separation mode
No full textThe invention relates to battery pack battery replacement decision-making method, device and system in a charging and replacement separation mode. The method comprises the steps of: acquiring batterypack state data, vehicle data, climate data and geographic data in a current time period; determining power consumption and actual mileage; calculating the battery replacement cost and the battery replacement price; making decision-making suggestions of battery replacement and charging opportunities; performing statistics and calculation according to the received data sent by the plurality of electric vehicles; carrying out SOH management on the battery packs, and determining the commercial use decision of a single battery pack or a certain batch of battery packs, wherein the commercial use decision comprises continuous use, periodic maintenance or retirement. According to the invention, the operation data, the vehicle data and the environment data of each battery pack can be analyzed andcalculated, the battery replacement cost and price are determined, and a battery replacement operator is helped to make strategic management decisions of the battery packs
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
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
