Telebeads: social network mnemonics for teenagers
No full textThis article presents the design of Telebeads, a conceptual exploration of mobile mnemonic artefacts. Developed together with five 10-14 year olds across two participatory design sessions, we address the problem of social network massification by allowing teenagers to link individuals or groups with wearable objects such as handmade jewelery. We propose different concepts and scenarios using mixed-reality mobile interactions to augment crafted artefacts and describe a working prototype of a bluetooth luminous ring. We also discuss what such communication appliances may offer in the future with respect to interperception, experience networks and creativity analysis.

SketchCam: Creative Photography for Children Jean-Baptiste LABRUNE 1,2
No full textThis paper describes the design and early testing of SketchCam, a camera that lets children take pictures through sketching. Our observations of children’s use of digital cameras led to insights about how children appropriate the screen in the picture-taking process. Inspired by their use of these cameras, we designed SketchCam, which enables children to capture images directly by sketching on a touch screen. We describe the results of our observations of children; the design of SketchCam, and the results of a preliminary study of a working prototype with four children aged three to six
Tangicam: exploring observation tools for children
No full textThis paper describes the design and early evaluation of the Tangicam, or tangible camera, a mobile device for children to capture and edit realistic pictures and videos. Our first experimental results show that the affordances of the Tangicam allow imitation learning and free playing in a context of tangible and augmented reality. Our goal is to create a simple and robust observation system that lets children produce narratives based on situated [51] video, audio and sensor data. We also want to explore how these temporal structures may allow children to describe themselves, other children or natural phenomena and how such situated time series may help develop new forms of synaesthetic and intersubjective constructions
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
