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
EveryWAN- An open source SD-WAN solution
No full textSoftware Defined Wide Area Network (SD-WAN) was originally proposed as an alternative solution to redesign the architecture of the WAN. Like its technology precursor Software Defined Networking, SD-WAN was aiming at simplifying the management and operation of the networks (with a particular focus on WAN scenarios) by decoupling the networking hardware from its control programs and using software and open APIs to abstract the infrastructure and manage the connectivity and the services. The SD-WAN architecture leverages SDN principles to securely build interconnections between users and the applications hosted in the clouds or in remote branches, by leveraging any combination of transport services With this paper we shed some light on the SD-WAN scenario and describe an open-source implementation which can be taken as reference. We call this architecture EveryWAn.It has been designed with SDN and NFV principles in mind, and leverages Cloud best practices to deliver to the WAN customers and the MSP the same benefits and the agility of the Cloud service providers. Moreover, we strongly believe in the openness of the SDN/NFV paradigms which can ease the development of new services and can foster the innovation in the SD-WAN deployments
Supporting future internet services with extensible in-band processing (EIP)
No full textNetworking architectures need to evolve to support the requirements of future Internet services and 6G networks. In this paper we propose an evolutionary solution that extends the IPv6 networking architecture fully supporting the needs of future services, called Extensible In-band Processing (EIP). The EIP solution considers a feature-rich networking layer, in which hosts and routers can cooperate by reading and writing the EIP information in the IPv6 packet headers, to support a number of use cases. Example use case are: advanced monitoring, semantic routing, deterministic networking, slicing and so on. This list of use cases is not exhaustive, as a key feature of EIP is to be extensible for the support of new use cases. In the paper we describe the initial design of the EIP header and protocol mechanisms. We have released an open source prototype implementation of EIP for Linux OS, based on the eBPF packet processing framework. The implementation includes tools for the generation of test EIP packets and for the protocol dissection of packets. A replicable testbed provides an early demonstration of the advanced monitoring and semantic routing use cases
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
High Performance Delay Monitoring for SRv6-Based SD-WANs
No full textSoftware-Defined Wide Area Networks (SD-WANs) are used to provide services to enterprises with geographically dispersed locations in a flexible and efficient way. We focus on SD-WAN services based on the Segment Routing over IPv6 (SRv6) technology. Performance Monitoring solutions are needed in SD-WANs to detect performance degradation and outages, and optimize network operations. In this paper, we describe a high performance solution for end-to-end delay monitoring for SRv6 based SD-WAN services. The proposed solution leverages the Simple Two-way Active Measurement Protocol (STAMP) to monitor the delay of an SRv6 path between two nodes called STAMP Session-Sender and Session-Reflector. We describe three implementations of the STAMP Session-Sender and Session-Reflector for a Linux software router and compare their performance. In particular, two implementations are based on user space processing and one is based on eBPF. The results show that the eBPF-based implementation outperforms the user space implementations and has a negligible impact on the forwarding capacity of the Linux software router
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
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
