Full text linkA User-Centric Protocol for Conditional Anonymity Revocation
No full textThis paper presents and evaluates an improved anonymity revocation protocol. This protocol can be used to strengthen anonymity revocation capability in a privacy-enhancing identity management system. This protocol is user-centric, abuse-resistant, and it provides enforceable conditions fulfillment. We assume the existence of 1 honest referee out of t designated referees (t > 1) chosen by users, and no collusion between users and referees. The security and performance of this protocol are evaluated
Toward an automatic classification of negotiation styles using natural language processing
Full text linkDO NOT USE PEARLDOI for this publication Labels Artificial Intelligence & Image ProcessingNatural LanguageClassificationVirtual artificial agentsNegotiationManage labels We present a natural language processing model that allows automatic classification and prediction of the user’s negotiation style during the interaction with virtual humans in a 3D game. We collected the sentences used in the interactions of the users with virtual artificial agents and their associated negotiation style as measured by ROCI-II test. We analyzed the documents containing the sentences for each style applying text mining techniques and found statistical differences among the styles in agreement with their theoretical definitions. Finally, we trained two machine learning classifiers on the two datasets using pre-trained Word2Vec embeddings
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
Why do People Adopt, or Reject, Smartphone Security Tools?
Full text linkA large variety of security tools exist for Smartphones, to help their owners to secure the
phones and prevent unauthorised others from accessing their data and services. These range
from screen locks to antivirus software to password managers. Yet many Smartphone owners
do not use these tools despite their being free and easy to use. We were interested in exploring
this apparent anomaly. A number of researchers have applied existing models of behaviour
from other disciplines to try to understand these kinds of behaviours in a security context, and
a great deal of research has examined adoption of screen locking mechanisms. We review the
proposed models and consider how they might fail to describe adoption behaviours. We then
present the Integrated Model of Behaviour Prediction (IMBP), a richer model than the ones
tested thus far. We consider the kinds of factors that could be incorporated into this model in
order to understand Smartphone owner adoption, or rejection, of security tools. The model
seems promising, based on existing literature, and we plan to test its efficacy in future studies
