Normative evolution and quality production. The case of olive oil
The olive oil sector is of notable economic and social importance in the province of Foggia. In this paper a significant number of oil samples produced in the countryside surrounding the province of Foggia from 1998-99 to 2001-2002 have been analysed in order to verify their quality, taking into consideration also the periodic revision of the body of legislation from the European Union which is constantly restricting its parameters, like for example the EC Regulation 1513/2001 which will come into effect on the 1st November 2003. The characteristic taken into consideration was free acidity, as defined by the EEC regulation 2568/91. In this paper we limited ourselves to consider only this parameter since the aim was to verify what effects the EC regulations 1513/2001 could have on the province of Foggia. If you consider the data obtained and the classification provided by the current body of legislation, you can see that almost all the samples are included in the category of extra-virgin olive oil. These considerations are valid even in view of the new EC Regulation 1513/2001 which will come into effect soon and which, as we have already said, provides for a different olive oil classification. As regards the oil produced in the province of Foggia, the research carried out allows us to state that it is undoubtedly of a higher quality
Evoluzione normativa e qualità delle produzioni alimentari: il caso dell'olio extravergine di oliva. Nota II
Con il Reg. CEE 2081/92 per i prodotti alimentari sono state istituite la “denominazione di origine protetta” (DOP) e la “indicazione geografica protetta” (IGP); per entrambe le denominazioni il Regolamento prevede che sia redatto un apposito disciplinare (art. 4) nel quale devono essere indicati: il nome del prodotto, la sua descrizione e le sue caratteristiche, l’area di produzione, gli elementi che comprovano la sua tipicità, la descrizione del metodo di ottenimento del prodotto, i riferimenti alle strutture di controllo, l’etichettatura, le eventuali condizioni da rispettare.
Con il Reg. CE 2325/1997 e il successivo Decreto del Ministero per le Politiche Agricole del 23/4/99 è stata istituita, per l’olio prodotto in provincia di Foggia, la DOP “Dauno”. Le caratteristiche al consumo contemplate dal relativo disciplinare di produzione sono: acidità, numero di perossidi, contenuto di polifenoli, panel test. Al fine di valutare la congruità di tali parametri alle caratteristiche della produzione olearia provinciale, nel periodo 1998-2002, su 180 campioni di olio rappresentativi dell’intera produzione provinciale, sono state determinate, in aggiunta ai parametri previsti dal disciplinare, le caratteristiche spettrofotometriche nell’UV e la composizione in acidi grassi. L’indagine ha consentito di suggerire
l’opportunità di modificare i limiti per alcuni dei parametri previsti dal disciplinare nonché di inserirne di nuovi. L’adozione di buone pratiche di coltivazione è stata valutata attraverso la ricerca di residui di fitofarmaci

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
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
