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
Indonesian Curcuma Competition in the World Market: Insight from Demand System Analysis
No full textCurcuma is frequently employed as an appetite enhancer and for medicinal purposes. In addition to being consumed domestically, Indonesian curcuma is also exported to the global market. This research identifies the manner in which Indonesian curcuma competes in the worldwide market, taking into account the fact that it also competes with curcuma from various other countries. The market position of Indonesian curcuma is identified using the Almost Ideal Demand System (AIDS) method. The comparator countries selected for this study are five curcuma exporters, namely India, the Netherlands, Germany, Spain, and the USA. The analysis utilised time series data from January 2013 to December 2022, and the identification results of this study indicate that Indonesian curcuma is a normal good with elastic and responsive properties to the global demand for curcuma. Furthermore, it is observed that Indonesian curcuma substitutes or replaces Indian curcuma. Conversely, Dutch, German, Spanish, and USA curcuma exhibit a complementary relationship with Indonesian curcuma. To enhance the competitiveness of Indonesian curcuma in the global market, it is imperative to augment the volume and quality of exports, with a particular focus on standardisation and enhancing the added value through processing. This strategic approach is expected to not only ensure price competitiveness with other exporters but also to expand the share of Indonesian curcuma exports in the global market
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

An automotive manufacturing company adopted Automated Guided Vehicle (AGV) to improve production efficiency and capacity. The AGV robot PIC faces difficulties in monitoring AGV robot operations and performing real-time troubleshooting while off the production line, with information on AGV problems reported via Handy Talky (HT). To solve the problem, a solution is proposed for the development and integration of AGV real-time monitoring system using data digitization from batteries, motors, and sensors on PLC, HMI, and Node-RED with Modbus TCP/IP protocol. Data transmission performance analysis was conducted to ensure system optimality by measuring delay, jitter, throughput, and packet loss using Wireshark based on ITU-T G.114 standards. The system was successfully integrated with FX3U PLC, Weintek MT8051iP HMI, and Node-RED. The results show an average delay value of 48.4 ms and packet loss of 0% when the AGV is idle, and an average delay value of 78 ms and packet loss of 0.07% when the AGV is running. The effect of Wi-Fi signals shows an average delay value of 76 ms and packet loss of 0.086% for medium signals, and an average delay of 150.5 ms and packet loss of 0.886% for low signals. The addition of a Wireless Access Point (WAP) extends the signal range, resulting in an average delay of 49 ms and packet loss of 0% on WAP 1, and an average delay of 64 ms and packet loss of 0.0475% on WAP 2. Continuous data transmission measurements (8 hours) show an average delay of 72.75 ms and packet loss of 0%. Based on ITU-T standard. G.114, the system integration of this AGV robot is in the good category
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
