Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
From project to process: school gardens as vehicle for territorial sustainability. A case study from the Milan metropolitan area.
No full textThe study will examine at first the great importance of food education by framing it in the wider context of some globally present critical phenomena. Accelerated urban population growth, dramatic shrinking of rural areas and food systems as well as progressive unsustainability are today profoundly altering our territories and ways of living. A key occasion for a worldwide reflection upon the latter is represented by the Milan 2015 EXPO, that however should be imagined not as limited temporal event but instead should be a stimulus for creating a higher awareness. Accordingly to this vision, in its core a part of the paper will analyze a bottom-up design and social experience, located in the Milan metropolitan area, that chooses the schools' network as a strategic mean for both future generations education and adult public sensitizing. In particular, the study will illustrate how a micro-architectural project (vertical garden prototype), if intended as a process (discussion and action catalyst involving simultaneously designers, public and private actors, and children), has the potential to address in effective way the poor conditions of current food education. The vertical garden, realized by the same students, is in fact conceived as a starting point for exploring broader themes like: food systems, water in urban environment, food packaging and recycling. Thus, the process goes beyond the school garden boundaries and aims at real positive impact for the overall territorial development. Within the conclusive section the paper will discuss the main difficulties to tackle with, and the potentialities to be valorized and experimented in other contexts
DALLA LOGICA INDIVIDUALISTICA ALLA REGOLAZIONE DELLA COMPLESSITÀ NELLA TUTELA DEL CONSUMATORE (E DELLE VULNERABILITÀ) NELL’ECOSISTEMA DIGITALE

Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
