Bike sharing for students’mobility: the case study of the new engineering hub in Naples, Italy
Full text linkThe mobility choice of university students represents one of the most interesting issue within the scientific literature of the sector, considering the impacts that these choices might have on congestion. In all the European cities where cycling mobility and bike sharing are experiencing a continuous growth, mobility policies have fostered the use of these transport alternatives. The bicycle, in the period between the end of the nineteenth and the first decades of the twentieth century, was the mostly chosen means of transport thanks to its characteristics of cheapness and elasticity in use. However, with the continuous technological development, the use of bicycles has increasingly reduced in favor of a mobility based mainly on private cars and motorcycles. The progressive deterioration of the livability of urban centers and neighboring areas has led public administrations of northern Europe to an overall reorganization of the transport system. The key words of the reorganization of transport are: " sustainable transport", "intermodality", "traffic calming". In this context, urban mobility policies have focused on fostering the use of bicycles at the urban level, increasing bike sharing in cities. In the city of Naples no initiative is promoted to make bike sharing accessible within university areas. In 2016 a new engineering hub was inaugurated located in San Giovanni a Teduccio, an Eastern borough of the city of Naples. The neighboring municipalities have proposed the idea of encouraging the use of bicycles to reach this hub. Among them there is the city of Portici, one of the most densely inhabited areas in the territory (with 12,000 inhabitants / km(2)), 4 km away from the new engineering hub in San Giovanni a Teduccio. Starting from these considerations, after showing the history of bike and bike sharing, the aim of this research is to evaluate the attitude to choose bike sharing for potential engineering students residing in Portici. For this reason, a mobility survey (RP and SP) was conducted at the high schools of the city of Portici. The results show that on average a student is willing to walk up to 900 meters to reach the bike sharing station. In the case that the bike sharing service is with pedal assistance charged of an annual cost of 30 euros, there is a higher attitude to choose bike sharing, but less attitude to walk to reach the station. Indee, in this case a student on average is willing to walk up to 600 meters to reach a bike sharing station

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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
