Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Il recupero e la distribuzione dei prodotti alimentari ai fini di solidarietà sociale: attuazione e risultati delle politiche di Regione Lombardia
Il presente rapporto analizza le politiche di Regione Lombardia in tema di recupero e distribuzione di prodotti alimentari ai fini di solidarietà sociale. Fra le numerose iniziative promosse dalla Regione negli ultimi anni, l’analisi si concentra sui due Piani di intervento biennali 2017-2018 e 2019-2020 realizzati in ottemperanza alla l.r. 34/2015. Il primo Piano 2017-2018 ha coinvolto 7 organizzazioni e a fronte di un investimento di quasi 1,6 milioni di euro sono state ridistribuite più di 20.000 tonnellate di alimenti destinati al sostegno di circa 300.000 persone in stato di bisogno. Il secondo Piano 2019-2020 (tutt’ora in corso) prevede uno stanziamento di 2,6 milioni di euro, coinvolgendo 10 organizzazioni (di cui 5 in continuità col Piano precedente) e mira a raggiungere oltre 315.000 beneficiari. Al di là dell’aspetto quantitativo, è importante sottolineare la volontà esplicita dell’azione regionale di migliorare la dimensione qualitativa degli interventi con percorsi di attivazione dei beneficiari: incrementando la distribuzione del fresco oltre al secco, incentivando il passaggio dal “pacco alimentare” all’emporio solidale e migliorando i percorsi di educazione alimentare. Dalle interviste svolte con le realtà solidali coinvolte nel Piano 2019-2020 emerge un rafforzamento della capacità organizzativa secondo gli stimoli del Piano stesso, anche se è probabile uno scostamento rispetto agli obiettivi posti all’inizio del percorso a causa dell’emergenza Covid-19. La ricerca ha rilevato come le risorse stanziate da Regione Lombardia siano considerate fondamentali dalle organizzazioni per affrontare rischi e bisogni alimentari, peraltro in forte aumento a causa della pandemia. Al di là della dimensione economica, senza la quale molti interventi non avrebbero potuto essere realizzati, emerge con chiarezza l’importanza del percorso condiviso avviato con le istituzioni regionali, e in particolare con la DG Politiche Sociali, che ha permesso l’implementazione dei progetti proposti ma anche, e soprattutto, una crescita delle organizzazioni. Pur in presenza di alcune criticità, l’azione di Regione Lombardia dimostra un significativo grado di efficacia nel perseguire gli obiettivi di recupero e distribuzione di alimenti ai fini di solidarietà sociale posti attraverso la relativa normativa regionale.This report analyses the policies of the Lombardy Region regarding the recovery and distribution of food products for the purposes of social solidarity. Among the numerous initiatives promoted by the Region, this analysis focuses on the two biennial intervention Plans 2017-2018 and 2019-2020, implemented in compliance with the Regional Law 34/2015. The first Plan 2017-2018 involved 7 organizations and, with an investment of almost 1.6 million euros, more than 20,000 tons of food were redistributed to support about 300,000 people in need. The second Plan 2019-2020 (still in progress) allocates almost 2.6 million euros and involves 10 organizations (5 of which in continuity with the previous Plan), expecting to reach over 315,000 beneficiaries. Beyond the quantitative aspect, there is an explicit will to improve the qualitative dimension of the interventions with activation paths for beneficiaries, increased distribution of fresh in addition to dry food, substitution of “food packages” with “solidarity emporia”, and so on. From the interviews carried out, it emerges that the institutions are definitely strengthening their organizational capacity, taking advantage of the stimuli of the new Plan 2019-2020, even though we can expect a certain deviation from the objectives set due to Covid-19. Overall, the organizations express a very positive opinion on both Plans, which financial resources have been fundamental to address increasing risks and needs. The availability of the DG Social Policies has been much appreciated, having created real paths of growth and development of projects together with the organizations; some critical issues are detected only on the methods of submitting applications and the related timing
Variations on the Author
“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
We 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
We 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
