Extending software complexity metrics to concurrent programs
No full textA metric for concurrent software is proposed based on an abstract model (Petri nets) as an extension of T.J. McCabe's (1976) cyclomatic number. As such, its focus is on the complexity of control flow. This metric is applied to the assessment of Ada programs, and an automatic method for its direct computation based on the inspection of Ada code is provided. It is pointed out, however, that wider experimentation is needed in order to better assess its effectiveness
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
Indicators for the Circular City: A Review and a Proposal
No full textThe theme of the circular city is currently much debated in the literature as a possible
strategy for achieving sustainability in urban areas. However, as a recent development it still has
many features in the making, one of the most important being the issue concerning monitoring
and the tool through which to achieve it. In the paper, therefore, the “indicator” tool is explored
in depth. Metrics represent a fundamental and complex aspect that is foundational to measuring
and quantifying the progress of results achieved with respect to the goals set. Currently, most
existing indicators are associated with specific aspects of the circular economy; there have been few
examples of indicators designed to assess the circularity of an entire city. The paper aims to identify
priority themes and describe a set of indicators to be used at the urban level. In the absence of an
established reference frame, themes and indicators were identified through a methodology starting
with an extensive literature search and careful analysis, including statistical analysis, of the scientific
literature as well as international and European strategies on the subject. A particular result of this
research is the definition ofa minimum set of indicators common to all cities, which can be applied
for comparative purposes
