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
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

A focus on company-stakeholder relationships in the light of the Stakeholder Engagement framework
No full textThis paper aims to investigate company-stakeholder relationships from a managerial and marketing perspective. The principal goal of the work is to identify possible drivers on which to act to improve opportunities for long-term and collaborative relationships between companies and stakeholders.
Building on the contributions on the topic of relationships between companies and stakeholders, the paper proposes an explorative research study carried out to suggest how strategies and behaviours of a sample of Italian Small and Medium Enterprises (SMEs) are aligned with the global stakeholder engagement framework.
Hypotheses are tested via a survey on a sample of Italian SMEs. Data are analysed using Structural Equation Modelling (SEM) in order to identify possible relationships between companies’ Market Share (MS) and their capabilities in understanding stakeholder’s strong beliefs; the alignment of organisational models of companies and stakeholders; their attention to involve stakeholders in their plans and strategies; their availability to give information on their plans and strategies to stakeholders; the transparency of their communication; and the level of communication between companies and stakeholders. The results are discussed from a theoretical and practical point of view
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

le frontiere nello sviluppo dei nuovi prodotti
No full textQuesto studio analizza le principali determinanti della competizione basata sul time-to-market dei nuovi prodotti utilizzando un'analisi comparativa tra due Produttori Automobilistici Europei basata sul metodo del Multiple Case Study Research. La metodologia si fonda sull'utilizzo di variabili di controllo -control variables- (caratteristiche dell'impresa e del modello) e performance specifiche (Tempistiche -Time to Market (TTM)- e Qualità -Quality-). Si evidenzia inoltre l'influenza che parametri esogeni quali la struttura organizzativa e la storia pregressa dell'impresa hanno nei confronti della sua capacità innovativa. L'analisi pone l'accento sulla gestione delle pratiche di co-development con i fornitori come determinante fondamentale. La cooperazione con una base di fornitori selezionati non solo consente notevoli miglioramenti alle tempistiche di sviluppo dei nuovi prodotti e risultati qualitativi simili se non migliori, bensì può risultare anche in uno scambio efficace di pratiche metodologiche da applicare anche a progetti futuri. Infine, l'analisi porta ad evidenziare come imprese in condizioni competitive peggiori siano più innovative rispetto alle loro dirette concorrenti di successo, certificando in tal modo l'importanza dell'esperienza pregressa dell'azienda sul mercato. Questo studio vuole fornire ai lettori sia alcuni suggerimenti pratici per fronteggiare la pressione competitiva diretta al time-to-market nello sviluppo di nuovi prodotti, che un avvertimento nel tentativo di evitare il rischio incombente di perdere la propria posizione competitiva dominante a causa di una sorta d'inerzia innovativa interna
Anatomia di un Recall. Lezioni dal Caso Toyota
No full textLe vetture Toyota, considerate le migliori al mondo, hanno sperimentato un susseguirsi di recall – volontari o forzati – che hanno costretto la casa giapponese a misure drastiche. Com’è possibile che ciò accada a un produttore che ha sempre fatto della qualità e della soddisfazione del cliente un cardine della filosofia di management e della cultura aziendale? Questo studio analizza i recall più recenti identificandone le cause principali – tecniche e gestionali – e gli effetti sia sulle decisioni aziendali sia sull’atteggiamento dei consumatori. Il caso dei recall di Toyota sollecita una serie di riflessioni sul legame tra strategie di crescita, processi operativi, sistemi di management, capabilities e reputazione di mercato che travalicano il settore automobilistico
