No full textThis paper relates to a design proposal answering the call for tenders issued by the Italian Ministry of Public Works about "pilot projects", i.e. test innovative interventions and projects aimed at improving road safety and at reducing the number of fatalities. The proposal, here presented, refers to the class concerning "Urban areas and land structures", at the point "Change from extra urban to urban road system". It represents a typical case of a National road (with its heavy traffic and its safety problems) that enters an urban area without appropriate devices for alerting drivers of the change of context. Highways and streets should be designed to meet the requirements of their specific class of users; problems arise when the users' needs are in conflict. In this sense, the crossings of small towns by national highways are very critical spots, since the perception and the use of the same space is completely different for highway's drivers and local users. In the considered case study, the National Highway Salaria, a consular road, passes through the small centre Osteria Nuova, part of the little town of Poggio Moiano, without significant changes of the road's geometrical characteristics; as a result, the 50 km/h speed limit, signalised at the urban area entrance, is not considered by most of the drivers, who, according to the police measurements, cross the area at speeds often faster than 100 km/h. The accident rate is very high and the severity index is 100 higher than the national one. The aim of the intervention is to improve the safety level of the highway, both for drivers and pedestrians, by the implementation of a system of measures targeted to induce users (mainly car drivers) to behave in a more respectful way, according to the rules in force and to the road functional feature

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
