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
Cognitive Extension and the Web
No full textThere has been a growing interest in recent years regarding the relationship between social interaction processes, technological artefacts and human cognition. Human cognition, it is argued, is often dependent on features of our social and technological environments, and changes to these environments can exert a profound influence on the kind of cognitive processing that we are capable of. Given this assertion, our attempts to understand a technology as pervasive as the Web assumes a new significance; for inasmuch as Web resources and technologies are apt for potent forms of cognitive extension and incorporation, we may fully expect such resources and technologies to fundamentally transfigure the space of human thought and reason. Our aim in this paper is to evaluate the legitimacy of this claim. We assess whether the current properties of the Web enable it to meet the criteria for cognitive extension that have been proposed in the philosophical and cognitive scientific literature. Our analysis suggests that the Web is capable of participating in the external realization of (at least some) human mental states, but that further work is required to leverage its full potential. Relevant capability targets for future research and technology development include (but are not limited to) a move from resource-centric to data-centric modes of information representation, enhanced mechanisms for information quality assessment, and improved opportunities for the active (re-)structuring and personalization of information content. We conclude that the Web does constitute a potentially important element of the bio-technological matrix associated with mind and cognition; however, we suggest that further technological innovation is required to enable it to participate in the external realization of human mental states and processes. The notions of distributed and extended cognition seem to be highly relevant in understanding the transformative potential of the Web in relation to human cognition, and the continued study of the psycho-cognitive effects of the Web should, we argue, be key elements of a mature web science discipline
The Network-Extended Mind
No full textWhereas the traditional view in cognitive science has been to view mind and cognition as something that is the result of essentially inner, neural processes, the extended cognition perspective claims that at least some human mental states and processes stem from complex webs of causal influence involving extra-neural resources, most notably the resources of our social and technological environments. In this chapter, we explore the possibility that contemporary and near-future network systems are poised to extend and perhaps transform our human cognitive potential. We also examine the extent to which the information and network sciences are relevant to our understanding of various forms of cognitive extension, particularly with respect to the formation, maintenance and functioning of extended cognitive systems in network-enabled environments. Our claim is that the information and network sciences are relevant on two counts: firstly, they support an understanding of the mechanisms underpinning socially- and technologically-mediated forms of cognitive extension; secondly, they serve to guide and inform engineering efforts that strive to enhance and expand our cognitive capabilities. We discuss the relevance and applicability of these conclusions to current and future research exploring the contribution of network technologies to military coalition operations
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
Shared Understanding within Military Coalitions: A Definition and Review of Research Challenges
No full textShared understanding is commonly seen as essential to the success of coalition operations. Anecdotal reports suggest that shared understanding enables coalition forces to coordinate their efforts in respect of mission goals, and shortfalls in shared understanding are frequently cited as the reason for poor coalition performance. In spite of this consensus regarding the importance of shared understanding, however, there are very few empirical studies that attempt to explore shared understanding in a military coalition context. This paper attempts to support future research efforts into shared understanding by proposing a specific definition for shared understanding and identifying a number of research challenges. Shared understanding is defined as the ability of multiple agents to exploit common bodies of causal knowledge for the purposes of accomplishing common (or shared) goals. This definition implies that agents possessing shared understanding will be capable of coordinating their respective behaviours in order to ensure the efficient realization of cognitive and behavioural objectives. We also identify a number of areas for future research into shared understanding. These include the factors that affect shared understanding, the effect of shared understanding on coalition performance, and the development of techniques to reliably measure and assess understanding in coalition environments
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
