Understanding and measuring password management behaviour
No full textRecent research has shown that people continue to exhibit risky password behaviour despite public advice campaigns on secure password behaviour. However, little attention has been given to understand why people persist in risky password behaviour, and how people perceive the risks and the benefits when they undertake password related activities. In this programme of research, I conducted five studies to understand people’s risk perceptions on password related activities; both qualitative and quantitative methodologies were employed, particularly online surveys using the Mechanical Turk crowdsourcing service. To check whether respondents were susceptible to social desirability in their answers, they completed the short version of Marlowe-Crowne social desirability scale. I also gathered feedback from senior researchers working in the area of usable security, to assess whether the range of behaviours and domains represented a good coverage of the password management space. The research makes a number of contributions, including a greater understanding of people’s password management behaviour, including generational differences in these behaviours; people’s perceptions of the risks of a range of password management behaviours; and the relationships between the perceptions of risk, benefit, and the likelihood of engaging in different password management activities. The research also presents valuable information to help researchers and usable security practitioners understand how people’s perceptions affect their management of their passwords. Finally, this programme of research proposes an initial version of a scale for assessing the perception of the risks of different password management behaviour. Future work is required to appropriately validate the scale. It can then be used in further research to investigate people’s understanding of and attitudes towards risk in the area of password management
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Consigliere evaluation: Evaluating complex interactive systems with users with disabilities
No full textConducting accessibility evaluations with users with disabilities is an important part of developing accessible interactive systems. Conducting such evaluations of systems which require complex domain knowledge is often impossible, as disabled users do not exist or are very rare. This paper presents a user evaluation method to address this problem, consigliere evaluation. A consigliere evaluation has the disabled user as the main participant, but they are assisted by an advisor, or consigliere, who understands the complex domain; the consigliere is in turn, monitored by an accessibility expert, who acts as an enforcer. As in all user evaluations, the disabled participant undertakes a series of tasks. But in a consigliere evaluation, if the task requires some particular domain knowledge or skill, the role of the consigliere is to provide appropriate information. However, it is easy for the consigliere, who usually does not have knowledge of the accessibility domain, to provide information not specifically about the domain, but about how to do the task in general. So the role of the enforcer, who is an accessibility expert, is to ensure this does not happen, and also to provide assistance and explanation if accessibility issues arise that the disabled participant cannot solve. The paper illustrates the consigliere method with a case study, the evaluation of Skillsforge, an online system used by a number of universities to manage progress of postgraduate students. This system requires considerable domain knowledge of the terminology and progression requirements for these students. It is used by university administrative staff, academic staff who supervise postgraduate students or are involved in monitoring students and the students themselves. The case study illustrates how the consigliere evaluation method works and some of the things which need to be considered in conducting the evaluation appropriately.Innovation Voucher Programm
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
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
