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

No full textFORCH: An Orchestrator for Fog Computing service deployment
Full text linkIn scenarios where resource locality is the key, Fog Computing helps in bringing the potentialities of Everythingas-a-Service (XaaS) closer to the end user, reducing both service time and load on the Cloud infrastructure. We designed and developed FORCH, a service model-aware Fog Computing orchestrator to dynamically allocate services and manage resources available on Fog nodes, in order to provide for different needs of the end users. An experimental test bed to validate FORCH architecture has been implemented and will be the subject of our live demonstration, showing the feasibility of the proposed approach running on different Fog node types and with different service models
New recovery energy turnstile achieved through research and innovation eco-design method (EQFD)
No full textThe present paper focuses on the recovery of energy from the unitary passage of people inside the turnstiles. Positioned at strategic points such as stadiums, buildings and fairs, the turnstiles are objects that interact with a large number of people, so we decided to take advantage of this peculiarity to get electricity immediately usable [1-3]. The issue of energy sustainability is increasingly discussed in terms of climate change that is undergoing our planet; hence an ever increasing awareness of avoiding energy losses in all phases of everyday life, even in those apparently unimportant. In our case, people do not have to change their habits or gestures during the turnstile approach, what changes is the concept of passing that becomes the protagonist and fundamental to reach our goal
A Multi-Protocol MEC-based Approach to Deploy and Consume IoT Services
No full textEdge computing is becoming one of the key areas for both academia and industry, opening up new opportunities and posing new challenges. In particular, IoT is one of the fields that could greatly benefit from the adoption of this paradigm. Actually, different solutions and protocols can be adopted for IoT data retrieval and processing, thus creating complex heterogeneous environments. We propose a practical demonstration of how a flexible Multi-access Edge Computing (MEC) approach could be used in multi-protocol scenarios to simplify the deployment and consumption of IoT services, by means of proper extensions to the service definition in the ETSI standard MEC interface
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
