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
Una Revisione Critica delle Linee Guida G.4
No full textNel corso degli ultimi trent’anni si è assistito ad un’ampia e rapida diffusione degli standard di ges- tione etica d’impresa. Sono stati prodotti più di 300 standard diversi allo scopo di incoraggiare la presa di responsabilità da parte delle aziende in merito a questioni di natura sociale ed ambientale. In questo la- voro è analizzato il Bilancio Sociale, uno strumento di rendicontazione che consente di comunicare in maniera efficace gli sforzi compiuti da un’organizzazione in materia di sostenibilità. Nella prima parte dello studio sono descritti i fattori che hanno determinato la diffusione di questo strumento, sofferman- dosi sul ruolo chiave avuto dagli stakeholder. Nella seconda parte sono analizzate due prospettive teoriche che giungono a conclusioni diverse in merito al rapporto esistente tra costi e benefici nella reda- zione di un Bilancio Sociale, e di come vari la scelta di adottare questo strumento a seconda del livello di onestà dell’impresa. Nella terza parte è descritto lo standard di rendicontazione di report sociali mag- giormente utilizzato dalle organizzazioni a livello globale, lo standard della Global Reporting Initiative (GRI).
Lo scopo di questo lavoro è quello di esaminare le critiche mosse al sistema GRI individuando le principali modifiche possibili.
Analizzando le novità introdotte con la terza revisione delle linee guida GRI (G.4), si è cercato di comprendere se siano state introdotte: misure per l’individuazione di obiettivi più stringenti in materia di sostenibilità; modalità per garantire la partecipazione degli stakeholder a tutto il processo di rendiconta- zione, compresa la fase di verifica dei risultati; misure per limitare la diffusione di bilanci sociali incompleti e contenenti informazioni poco valid
Main drivers to traceability systems in the food supply chain
No full textTraceability is an increasingly important and essential tool within the agri-food sector. It rep- resents a very useful tool for analyzing, monitoring and managing the flow of products. In recent years, food traceability has become a key element which all companies have to manage (Myae and Goddard 2012). Food safety is now essential for all operators in the supply chain, and trace- ability is one of the elements necessary to ensure security and to connect consumers and market operators (Liu, Cheng, and Zhang 2013). Food security can be achieved by increasing the quality of products and services taking into consideration the whole supply chain, thus implementing a system that involves all stakeholders, from raw materials to final consumers (Pascu 2013). In ad- dition to ensuring the safety and wholesomeness of food, traceability systems are meant to foster a better relationship with consumers, providing them with information about the products they are buying (Menozzi et al. 2013).
In recent years the scientific community has significantly developed the debate on traceabil- ity, due to various social issues and events that have set food security at the center of public debate. If beforehand tracking was implemented voluntarily by the companies in the supply chain, today it is regulated in many countries with mandatory laws, that rule the basic principles to be followed by market operators (Schwägele 2005).
The literature has dealt to analyze and describe various aspects of traceability as the definition of the concept, the elements for its successful implementation, the technologies, the benefits and barriers to its implementation (Bosona and Gebresenbet 2013). The objective of this paper is to investigate briefly what are the key drivers that have led in recent years an increasing implemen- tation of traceability systems in the food supply chain. Initially, a general analysis is carried out on the definition of traceability and its significance in terms of economic theory. In the second part a subsequent examination of the reasons that lead companies to invest in traceability systems is presented

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
