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
Putting trajectories to work: translating a HCI framework into design practice
Full text linkOne major challenge for the academic Human-Computer Interaction (HCI) research community is the adoption of its findings and theoretical output by the interaction design practitioners whose work they are meant to support. To address this “research-practice gap”, this thesis takes the example of trajectories, a HCI conceptual framework derived from studies of mixed-reality performances spanning complex spaces, timeframes, participant roles, and interface ecologies. Trajectories’ authors have called for their work to be used to inform the design of a broader variety of experiences. This thesis explores what is required to fulfil this ambition, with a specific focus on using the framework to improve the experience of live events, and on professional design practitioners as the users of the framework. This exploration follows multiple approaches, led both by researchers and practitioners.\ud
This thesis starts by reviewing past uses of the trajectories framework – including for design purposes – and by discussing work that has previously tried to bridge the research-practice gap. In a first series of studies, the thesis identifies live events – such as music festivals and running races – as a rich setting where trajectories may be used both to study existing experiences and to design new ones. This leads to a series of design guidelines grounded both in knowledge about the setting and in trajectories. The thesis then discusses multiple approaches through which HCI researchers and practitioners at a large media company have joined forces to try to use trajectories in industrial design and production processes. Finally, the last strand of work returns to live events, with a two-year long Research through Design study in which trajectories have been used to improve the experience of a local music festival and to develop a mobile app to support it. This last study provides first-hand insight into the integration of theoretical concerns into design.\ud
This thesis provides three major classes of contributions. First, extensions to the original trajectories framework, which include refined definitions for the set of concepts that the framework comprises, as well as considerations for open-ended experiences where control is shared between stakeholders and participants. Secondly, a model describing the use of trajectories throughout design and production processes offers a blueprint for practitioners willing to use the framework. Finally, a discussion on the different ways trajectories have been translated into practice leads to proposing a model for locating translations of HCI knowledge with regards to the gap between academic research and design practice, and the gap between theoretical knowledge and design artefacts

Media trajectories in large-scale live events
Full text linkLarge-scale live events, such as marathons and music festivals, involve a large number of participants with a variety of roles, motivations and levels of engagement, as well as a variety of media, from user-generated content to national media. We interviewed runners and spectators in marathons to understand this category of experiences and derive design guidelines. A first analysis of this data, combined with the trajectories framework, shows potential for designing tools supporting retelling the story of these events
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
