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
Cinque vie per ridurre la diseguaglianza tra i redditi

Previdenza, l’anno della flessibilità
No full textIl capitolo di Carlo Mazzaferro fa il punto sulle principali novità che hanno riguardato il sistema pensionistico. Sotto il profilo della sua sostenibilità, il rapporto della spesa per pensioni sul Pil sembra aver arrestato la corsa dopo la forte crescita negli anni della grande recessione. Questo andamento è spiegato sia dalla modesta ripresa del numeratore, sia dall’esplicarsi degli effetti di risparmio incorporati nella riforma Monti-Fornero. Riguardo al secondo effetto l’orientamento dell’esecutivo è stato sostanzialmente quello di confermare nella sostanza la loro dinamica. È stato così per la sentenza della Corte costituzionale di giugno 2015, relativa al mancato adeguamento all’inflazione delle pensioni di importo superiore a tre volte il minimo e più in generale questo sembra l’orientamento riguardo al tema della flessibilità in uscita. Se da un lato la questione degli esodati sembra aver trovato una sua sistemazione normativa con annessi costi finanziari e distributivi, dall’altro gli interventi messi in campo nella legge di stabilità per il 2016 non sembrano in grado di fornire una risposta adeguata alle attese di coloro che ritengono opportuno un ammorbidimento delle norme relative all’uscita per pensionamento dal mercato del lavoro, sia per venire incontro alle eventuali esigenze dei lavoratori, sia per fare fronte alle deludenti performance dell’economia italiana in questa lunga fase di recessione. Le recenti proposte relative alla costituzione di un mercato per il finanziamento dell’anticipo pensionistico, peraltro riservato ad un numero ridotto di generazioni, suggeriscono che in tema di pensioni gli aggiustamenti nel prossimo anno finanziario non potranno che essere minimi e a costi ridotti per il bilancio pubblico
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
Insurance liabilities fair value and term structure of interest rate: considerations and applications.
No full textThe aim of thi article is to analyze the term structure of interest rates role for evaluating a fair value of a life insurance business. In particular, we compare the fair value accounting impact on reserve evaluating using a constant interest rate and two stochastic processes: Vasicek and Cox Ingersol Ross models. An application to an endowment policy is presented
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
