Age matters
No full textInternet-based, mobile and pervasive technologies provide the means for older people to establish and maintain intergenerational relationships over long distances. However the significance of this intergenerational context has been largely ignored when considering potential interactions and the design of new technologies. This workshop aims to explore what the important issues are when considering intergenerational contact as a significant context for design. The overarching objective of this workshop is to identify key research themes in respect of intergenerational communication and its implications for the design of interactive systems
Observations on Pervasive Information Systems Design
No full textThis paper seeks to lay out a number of observations on Pervasive information systems design that have been made during the Chawton House project, an augmented field trip for school children. After laying out the Chawton House case study, the information infrastructure is described and arising issues are examined concerning design for persistence, empowerment of non technical users, and re-use
From the lab to the OB truck: Object-based broadcasting at the FA Cup in Wembley Stadium
Full text linkWhile traditional live-broadcasting is typically comprised of a handful of well-defined workflows, these become insufficient when targeting multiple screens and interactive companion devices on the viewer side. In this case study, we describe the development of an end-to-end system enabling immersive and interactive experiences using an object-based broadcasting approach. We detail the deployment of this system during the live broadcast of the FA Cup Final at Wembley Stadium in London in May 2018. We also describe the trials and interviews we ran in the run-up to this event, the infrastructure we used, the final software developed for controlling and rendering on-screen graphics and the system for generating and configuring the live broadcast-objects. In this process, we learned about the workflows inside an OB truck during live productions through an ethnographic study and the challenges involved in running an object-based broadcast over the Internet, which we discuss alongside other gained insights
Does it Matter who is Holding the PDA in a Mobile Learning Experience?
No full textMobile technologies, such as PDAs, are increasingly being used to create innovative mobile learning experiences for children. Collaboration around use of the PDA has been identified as a key benefit. In this paper we identify the issue of whether it matters who is holding the PDA, and in particular whether there are gender effects at play. We present a preliminary study where we examine the behavior of pairs of children using PDAs in a literacy fieldtrip according to which member the pair held possession of the PDA at any time and whether PDA use influenced who initiated action. Our results indicate that initiating action could be independent of technology 'ownership' for girls, but that for boys initiating action might be more heavily influenced by who was holding the PDA. However, these findings are based on a limited sample and are indicative only. The main contribution of this paper then is to highlight the issue of possible gender effects on how PDAs are used in mobile learning experiences and point to areas for future research to understand how collaborative interactions take place and whether or not it does matter who is holding the PDA
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
Stepping into cooperative buildings
No full textIf we are stepping out of windows, what are we stepping into? We suggest it is into cooperative buildings. For the foreseeable future, at least, we can identify two major characteristics of the cooperative building. The spaces of the building will be augmented in various ways, providing an ambient environment that bridges spatial discontinuities in workgroups and provides a continuous window into the state of the virtual world. Secondly, the ways in which the spaces themselves are used will evolve to be more congruent with the fluid, dynamic and distributed nature of the work taking place in the building. These two characteristics are deeply interconnected. This evolution need not happen entirely in the physical world; the essence of a cooperative building will become the way in which it mixes both physical and virtual affordances to support the workaday activities of its inhabitants
