Reliability prediction for service-oriented computing environments
No full textA key issue in the development of service-oriented computing applications is the dynamic and efficient prediction of their overall quality to appropriately drive the selection and assembly of services. This article focuses on the reliability quality measure and presents an implementation of a reliability prediction methodology that respects SOC's decentralization and autonomy principles. Despite the focus on reliability, you can extend the architecture to the prediction of other quality measures
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
Real time ridesharing: Understanding user behavior and policies impact: Carpooling service case study in Lazio Region, Italy
No full textWorkplace relocation from suburb to city center: A case study of Rome, Italy
No full textAs metropolitan areas are generally characterized by decentralized jobs because of a car-based living, in this paper we focus on the feasibility of a “reverse” workplace relocation. The case study of a firm relocation from Rome’s suburbs to the historic city centre is presented. The new location, where the employees will have to move, is in a restricted traffic zone. A behavioural-based method was developed to forecast the future mode split of the employees of the firm being relocated. Next, the model’s estimates were compared with the results from a focus group interview. This approach is expected to provide reliable estimates of the mode choice, as it combines the standard discrete choice modelling for the mid-term forecast with the results from a focus group interview for the short-term forecast. The results from the discrete choice model overestimated the choice of public transport, whereas from the focus group interview it emerged that park & ride is expected to be the most chosen mode in the short-term. Finally, this case study suggests that a workplace relocation from the suburbs to the center could encourage the employees to lessen car-dependent habits
