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
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

Full text linkThe project, funded through the core research fund, comprises a partnership between PNDC, Lupovis Ltd and the PNDC’s key DNO members UKPN, SPEN and SSEN and is delivered in collaboration with UK Power Networks and Lupovis
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
Remote and Rural Resilience for EV Infrastructure
Full text linkReliable and secure communication technology is one of the key requirements to ensure the flow of EV charging services for reasons like digital transition in pursuit of net zero targets. A wide range of communications technologies can be used to enable the connectivity needed to monitor the EV charging stations. In the hard-to-reach areas, the suitability of Low Power Wide Area Networks (LPWAN) technologies such as NB-IoT, LoRa and RPMA, and BGAN satellite communication along with G4/G5 and private LTE vary based on their availability, the main end applications and the associated costs. PNDC has been approached by HITRANS to look at the key challenges and solutions that face the availability of communication technologies and the impact of switching off the 3G network in the. In this report, PNDC has identified the key challenges of EV infrastructure in remote and rural areas along with the appropriate solutions and the cost associated of each recommended option. This project has explored the key technologies that can be deployed in hard to hard-to-reach remote and rural areas, taking into considerations their main advantages, disadvantages and estimated costs for EV charging infrastructure. The report identifies potential future technologies that could be used or easily Moray, Western and Northern Scottish Isles including Shetland and Orkney deployed to meet the communications and cyber security requirements for EV charging in the Scottish Isles. The report also focuses on the communication requirements for the EV charging infrastructure and covers the available communication technology options that are most suited for this application – highlighting the advantages and limitations of each option. The report includes Learning from previous relevant innovation projects and previous experience we have built over the previous years and it answers the following questions: • What are the recommended communication technology options to be used in connecting the EV charging stations in the hard-to-reach areas? • What are the key requirements to enable the functionality of the EV charging by reliable and secure communications? • What is the impact of switching off the 3G network in remote and rural areas of Scotland? • What are the short/long terms communication solutions to be considered in the EV charging? During this project, it has been found that the right connectivity for EV infrastructure in the highland namely some areas in Moray, Western and Northern Scottish isles including Shetland and Orkney might be limited and in some spots, the only immediate option is to go through the expensive satellite communication technology. To ensure the best signal availability from the mobile operator, multinetwork (roaming) 4G SIMs can be the option to maximise connectivity in rural and hard-to-reach areas (assuming that at least one mobile provider can have coverage). It has been also found that some legacy charging stations which use 3G networks for their connectivity might be affected by the 3G shutdown and they require 3G-to-4G modem upgrades. Some manufacturers can easily upgrade the mobile connectivity module for some type of charging points, whereas, some other models may not be upgradable. As the age of the charging station along with its model and associated communication modem and its functionality will identify whether it requires replacement or upgrade
Cyber Deception for Integrated Energy Systems: Cyber-Attacks Simulations and Defense Mechanisms
Full text linkAs the Operational Technology (OT) domain is constantly evolving, innovative approaches are needed to enhance existing cybersecurity systems. By strategically hosting intelligent cybersecurity tools (decoys - ‘Snare and Prowl’) both within and outside the utility network operator’s environment to mimic faux services and targets, internet-based, in-network adversaries, and Advanced Persistent Threats (APTs) are identified and engaged. Moreover, decoy Techniques, Tactics, and Procedures (TTPs) are tracked for attack characterisation based on their Threat Intelligence Profiles (TIPs) and narratives employed to effectively discern the attacker's capability to laterally progress across the network. This poster shares the lessons learned from a proof of concept study to investigate the capabilities of a cyber deception framework within an operational technology energy network to detect, analyse and alert of internal and external facing threats. In this study, different cyber attack scenarios were emulated in an OT environment with and without cyber deception frameworks. The case study trial is based on servers and database attack simulations critical for a more flexible, reliable, resilient, secure and sustainable integrated energy system. In attack scenario 1, breadcrumbs are used to prevent an attempt to attack narrative deployment for Apache and SSH Servers. In the second attack scenario, decoys detect attacks with indicators of intelligence based on privileged access through active port scans. In attack scenario 3, lessons on the impact of network environment changes on the overall system’s security are monitored. In each of the test scenarios, the Common Vulnerabilities and Exposures (CVEs) specific to Distribution Network Operators (DNO), TTPs leveraged by adversaries, and strategic locations within the DNO network for deception deployment were identified to improve system security
