Making urban data experienceable through vibrotactile feedback and engaging visualizations.
No full textEngaging people to actively collect, use and interpret data about their personal surroundings appears to be a promising approach which may lead to a shift in their mobility behavior. Our approach is to design and realize technology-based artefacts through a user-centered design process that motivates users to gather urban data such as air pollution and noise levels. Making the collected information experienceable for the users either bodily through vibrotactile feedback or by presenting data in an engaging, inconvenient and artful way is considered to enhance the users´ participation. This use of urban data directly connects the information with the actual place where people live and work and show citizens quality of life measurements in their own city quarter. In this paper we suggest two different approaches to achieve higher awareness towards urban data: The Vibro-Walk, which is a device that allows users to measure CO2 values and make them experienceable through tactile output. The CO2 flower is an artful and easy to use survey tool that confronts people with their actual mobility behavior and maps it to the growth of a plant
Support social awareness across distributed work groups with interactive tangible devics
Full text linkMitarbeiterInnen die gemeinsam innerhalb einer Arbeitsgruppe tätig sind, entwickeln eine Art passive Aufmerksamkeit gegenüber ihren KollegInnen, die durch den Begriff 'social awareness' gekennzeichnet ist. Sie hören die Gespräche Ihrer KollegInnen, bemerken es, wenn jemand durch den Korridor geht oder sich einen Kaffee zubereitet. Solche Hintergrundaktivitäten rufen zwar nicht die volle Aufmerksamkeit einer Person hervor, werden aber dennoch wahrgenommen und erzeugen ein Gefühl für den Rhythmus einer Arbeitsgruppe. Genauso wichtig wie dieses Rhythmusgefühl für Arbeitsgruppen ist, die in räumlicher Nähe zueinander arbeiten, genauso wichtig ist es auch für getrennte Arbeitsgruppen, da sie zur selben Organisation gehören und daher auch ähnliche Ziele verfolgen. Die Untersuchung inwiefern Technik einen Beitrag zur Unterstützung von 'social awareness' zwischen entfernten Arbeitsgruppen leisten kann um das soziale Gefüge zwischen den Gruppen zu stärken, ist das Hauptziel dieser Diplomarbeit. Als Forschungsfeld für die Untersuchungen im Rahmen der Arbeit bietet sich das Institut für Gestaltungs- und Wirkungsforschung an der TU Wien an, da es aus drei räumlich getrennten Arbeitsgruppen besteht. Innerhalb jeder Gruppe gibt es zwar regen Austausch unter den KollegInnen, auf Gruppenebene beschränkt sich dies jedoch auf offizielle Meetings und Aktivitäten die eher auf individuellem Level stattfinden. Es besteht die Anforderung die informellen Kontakte zwischen den Gruppen auf Gruppenebene zu stärken und so auch die Gruppenbindung zu verbessern. Um dieser Anforderung nachzukommen, ist es notwendig die konkrete Arbeitssituation der Gruppen zu analysieren sowie die Wünsche und Bedürfnisse der Gruppen zu identifizieren. Basierend auf diesen Erkenntnissen soll ein Prototyp entwickelt und für einen bestimmten Zeitraum in den Räumlichkeiten der Gruppen installiert werden.Employees working in co-located workgroups develop a sense of awareness about their colleagues. They hear their colleagues talking to each other, they recognize them walking through the offices or making themselves a coffee. Such subtle activities appear in the background without calling for focal attention but still being perceivable. As important as awareness is for co-located workers, as important it is to support awareness across distributed workgroups, because they belong to the same organization and therefore are following similar goals. To investigate how technological artifacts can contribute to the support of awareness and enhance social bindings across distributed workgroups is the main objective of this thesis. As research field for the investigations within this work, the Institute of Design & Assessment of Technology at the TU Vienna appears to offer a promising environment for a case study, since it comprises three distributed workgroups. Within each group there is frequent exchange among the colleagues, but there is less contact at the group level besides official meetings and occasional conversations on a personal level. There is a certain request by the groups to enhance and support informal exchange for all members at the group level. To be able to address this request through the support of technology, the context of the application has to be explored in terms of examining already existing group habits as well as investigating the wishes and needs of the future users towards such a system. Based on these initial insights a working prototype will be designed and implemented at the groups- facilities for a certain period of time

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
