A service engineering approach to inter-domain TMN system development
No full textThe deployment of service management systems in a multi-service environment opens a whole area of issues. Requirements for openness and reusability can be satisfied by following a service engineering approach where the service management functionality is decomposed to reusable service components. Such an approach that was based on TMN technology is presented in this paper and conclusions are drawn about the potential of other available technologies with regard to service management
Public transportation, ioT, trust and urban habits
No full textThe technological compound known as Internet of Things is
enabling massive transformations in many fields. In this paper, we deal
with one emerging scenario, Mobility as a Service, where the interplay
between technical, regulatory and social aspects is intense. We advocate
the need for interdisciplinary research, taking into account the different
facets of a system which, in summary, aims at improving the quality
of urban life by collecting personal data, tracking citizens’ movements,
correlating them with many other sources of information, and making
the results widely available
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
Enriching lifelong user modelling in a social networking and e-commerce era
No full textLifelong User Modelling is an area that aims at harvesting the massive volume of web-based user information, so that it can be used for educational long-term services. Although an amount of research has addressed this issue from an educational angle, by finding ways for educational peer systems to exchange data sets among them, little has been done to investigate the potential of the social networking and e-commerce domains in the Lifelong User Modelling vision to enable Lifelong Learning services to be used.This thesis presents a Scrutable User Modelling Infrastructure (SUMI) that can accommodate current social networking and e-commerce services for allowing the exchange of user data among these services and educational systems, for potentially improved personalisation services. Special focus has been given to three user modelling aspects: interoperability, scrutability and privacy. The suitability of SUMI regarding these aspects is tested by developing and evaluating a prototype service. The prototype SUMI service focuses on making the infrastructure scrutable, in terms of allowing users to have control of their imported models in SUMI, while also offering various controls for safeguarding the privacy of their information in SUMI. To assess our interoperability design decisions, four successful simulation tests have been conducted. To evaluate the proposed scrutability and privacy user privileges, two user-based evaluations have been carried out. For each evaluation, the method and results are described. Overall results have revealed that participants have expressed their general acceptance of having available such an infrastructure and service, while favouring a more holistic approach when exposed to such an environment
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
