Therapists as designers: An initial investigation of end-user programming of a tangible tool for therapeutic interventions
No full textThis paper presents a pilot study on end-user programming by therapists of a tangible tool for children on the autism spectrum. The core design ideas were to use detailed natural language descriptions of states and events, and an incremental process to facilitate the programming task. Our study provides initial evidence of the feasibility of this approach
SMARTER: an IoT learning game to teach math
No full textIn this paper, we present the preliminary implementation of SMARTER, a tangible tool for supporting children in learning the basics of mathematics, which has been loosely inspired by the Cuisenaire rods. The tool exploits the power of tangible manipulation offered by physical materials coupled with the possibility of providing contextual and engaging feedback provided by digital tools. An original and important goal of the SMARTER tool is to allow teachers to fully customize the experience of use by exploiting end-user development
Toward a Better Understanding of End-User Debugging Strategies: A Pilot Study
No full textIn this paper, we describe a pilot study aimed to explore strategies used by non-programmer users to test trigger-action rules for customizing an IoT device. The main goal of our research was to examine strategies used by participants to detect and solve errors. In the pilot study, we asked non-programmers to imagine testing a set of rules, some of which were bugged. The pilot study was meant to understand the feasibility of this approach to investigate users' mental models while performing this kind of task
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
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
