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
Möglichkeiten des User Interface (Re)Designs in späten Projektphasen
Full text linkEin Bewusstsein für Design erfreut sich in Softwareunternehmen zunehmender Beliebtheit, dennoch sind nach wie vor vorwiegend die EntwicklerInnen gleichzeitig die DesignerInnen eines Softwareprodukts.Erst wenn sich ein Produkt weniger erfolgreich entwickelt als erwartet oder Probleme auftauchen, wird Design als Aspekt einer Produktentwicklung in Betracht gezogen. In dieser Masterarbeit soll diese Situation, deren Ursachen und die Auswirkungen auf die Qualität eines Softwareprodukts beleuchtet werden. Als Gegensatz dazu sollen ein idealer Designprozess, insofern ein solcher existiert, und dessen notwendige Schritte theoretisch abgehandelt werden. Die Masterarbeit wurde von einem Projekt, in dem das Interface eines Document Designers entwickelt wurde, begleitet. Das Projekt wird unter den beschriebenen Aspekten beleuchtet und einer Reflexion unterzogen. Abschließend werden mit Hilfe der Auseinandersetzung mit dem Projekt und den theoretischen Gesichtspunkten die Möglichkeiten des Designs in späten Projektphasen diskutiert. Ziel ist es, ein Bewusstsein für Design und die Notwendigkeit einer Preproduction-Phase in Softwareprojekten zu schaffen.Although there is a growing awareness for design in software companies, programmers still assume the role of the designer too. Only when a product is less successful than expected, or when problems arise, design is taken into consideration as an integral part of the software development process. In this master's thesis this common approach in product development, its causes and its effects on a software product shall be investigated. Secondly, in a theoretical discussion, this approach will be contrasted with a suggestion for an ideal design process including its necessary steps. The master thesis was accompanied by a project, where the Interface of a Document Designer was developed.This project will be considered and reflected against the background of the described theoretical aspects. Finally, the project and the theoretical basics, as well as the possibilities of Design in late project phases will be debated. The objective is to raise awareness of the importance of a preproduction phase before implementing in software projects
From gardens to fridges : technology design considerations for less food waste
Full text linkDie Reflexion auf die empirischen Ergebnisse der Interviews und Fallstudien, präsentiert als Hauptbeitrag Technologie- und Designüberlegungen für den sozialen Wandel aus einer praxistheoretischen Perspektive. Diese zeigen auf die Bedeutung des Verstehens und Respektierens von komplexen Abläufen, sowie eine Sensibilisierung für soziale Organisation und Materialität im alltäglichen Leben. Weiters werden Positionen zur Konzeptionierung von Problemen und Lösungen, ein kritisches Bewusstsein zu Interventionen, sowie politische Implikationen im Design diskutiert.Consumer food waste in industrialised countries is an ethical, social and ecological dilemma requiring an understanding of existing practices and sensible interventions. This topic has received little attention in HCI yet, and the question where and how to intervene with digital technologies is a challenging endeavour. This PhD research contributes to an understanding of everyday food practices and informs possible ways of technology interventions towards reduced food waste. To understand everyday food and waste practices, I conducted an interview study with in-home tours in fourteen households. The analysis, oriented by social practice theory, points to food waste emerging as a later consequence from multiple other moments of consump- tion within practices of planning, shopping, (over-)buying, storing, cooking, gardening or socialising. These practices are embedded in the social and material organisation of every- day life and make it demanding for technologies to intervene or support. The findings of the interview study inspired and informed six design proposals for digital technologies poten- tially supporting #1 reflection; #2 informed choices; #3 communities of alternative practice; #4 reconnection to food sources; #5 promotion of public interest; and #6 activism; To learn from technology use embedded in people-s everyday food practices, I draw upon three technology case studies. I designed, developed and studied the mobile Food waste diary application and Fridge cam to probe deeper into #reflection and #informed choices. The findings of the two case studies point to the usefulness for some participants, and everyday life as being dominated by social and material circumstances where it is difficult for tech- nologies to intervene. The third case study on the existing Foodsharing platform uncovers the aspects of a #3 community of alternative practice, and the promoting of new narratives and practices that technologies and media are involved in. The empirical findings of the interviews and case studies, reflected along social practice theory, draw out the main contribution as technology design considerations for social change. These considerations highlight the significance of understanding and designing technologies for the messiness of everyday life, and being sensitised towards social organisation and materiality. Positions of how solutions and problems are framed, a critical enquiry into interventions, and the politics inherent to design are finally discussed
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
