    Reconciling the what, when and how of privacy notifications in fitness tracking scenarios

    No full text
    The increasing number of fitness tracking wearables deployed worldwide poses challenges to the privacy of their users, esp. in terms of transparency. Privacy notifications facilitate transparency by providing users with situational awareness about the pro-cessing of their personal data. We present the results of two online surveys including English-speaking (n(Eng) = 154) and German-speaking (n(Ger) = 150) users of fitness track-ing devices from Europe, conducted to elicit determinants of notification settings. We found evidence for the perceived usefulness of privacy notifications, and for concordant predictors in terms of when and how users prefer to be notified about personal data processing in 12 scenarios related to fitness tracking

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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

    Usable Access Control

    No full text
    The research described in this work can significantly simplify and facilitate the creation and configuration of secure access control rule sets. Access control is used to provide confidential data or information only to authorized entities and deny access otherwise. Access control mechanisms can be configured with access control rule sets that need to be created and maintained by the users or administrators. The research commences by answering the first research question: 1. How can access control be integrated into future products? Basic concepts are presented and integrated into a holistic design. The latter is embedded into a general framework, which was developed by an academia-industry consortium, and in which the author participated. Questions arise regarding usability aspects of access control mechanisms. An analysis of security services in the beginning of this dissertation shows that, especially for access control mechanisms that are managed by casual users, a high level of usability is required because individual preferences of the data owner have to be taken into account. Analysis of how the core security objectives (see Section [sec:Core-Security-Principles]) can be achieved identifies a usability gap regarding the generation and configuration of access control rule sets. Automation is not fully possible because individual preferences of users need to be considered. Related research questions are: 2. What are the requirements for usable access control rule sets? 3. What are formally founded quantifiable measurements for those requirements, and how can these measurements be used to support users in generating of usable access control rule sets? To answer these questions, a systematic analysis of expert opinions and related work was performed. The results of that analysis were grouped into categories and further refined into six informal requirements. The six informal requirements were mathematically formalized and six associated sets with respective linear metrics were derived. These formal tools are used to automatically calculate additional information about the actual access control rule set to support users in generating and optimizing the rule set properly. Two user studies were carried out to validate and evaluate the research and the findings presented in this work. They demonstrate that our metrics help users generate statistically significant better rule sets. The dissertation concludes with an outlook and a vision for further research in usable access control rule set configuration

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    We 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
