INTERSTIZI URBANI: SPAZI DI POSSIBILITÀ? ESPLORAZIONI URBANE E PRATICHE INFORMALI ATTORNO ALLA SS 554 «CAGLIARITANA»
Full text linkIn this paper, I explore the hypothesis that the interstices around urban motorways could be intended as spaces of creative, political, and performative experimentation outside planning and market logic. Urban interstices can be thought of as the negative of the city and part of a counter-utilitarian discourse, leading to great flexibility in the production of different urban forms.Re-interpreting Gibson-Graham's politics of possibility I re-read urban interstices around motorways as spaces of possibility, in which other spatial forms and dynamics are made visible, conceivable, and thus possible. In the literature on interstices, the emphasis on spatial possibilities is present but never posed in Gibson-Graham's feminist, performative, and transformative terms. The reading of urban interstices as spaces of possibility arises from the exploration of the interstices around the SS 554 "Cagliaritana". In particular, I will provide an understanding of the informal practices taking place in it as non-conflictual political claims towards a different way of producing urban space, that makes the interstices spaces of possibility

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
Third mission and espoused values of Italian universities: an investigation on official documents
No full textThis study examines the espoused values of Italian universities that emerge from statutes with the aim of eliciting patterns of representation of the third mission, which embraces all the activities by which universities contribute to the economic and social development of society. Since all statutes were updated between 2011 and 2012 because of a law enacted on 30 December 2010, n. 240, it is timely to use Italian universities to highlight current patterns of representation. Using a qualitative content analysis performed with Atlas.Ti (Muhr, 1994), seventy-five statutes were analyzed by focusing on core missions, functions attributed to the third-mission activities, and primary tasks of the organization vis-à-vis its environment. By relying on the systematic association between codes created to extrapolate the embodied meaning of the text and units of analysis, results have shown four organizational archetypes in the third mission: 1) Need for coherence, with an emphasis on the need to respect the functions of public institutions regarding the third-mission activities; 2) Exploitation, which focuses on patent disclosure; 3) Openness to participating in external change and satisfying external needs; and 4) Old School, with a focus on entrepreneurial activities as a source of funding. Our analysis leads to proposals for future research
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
