No full textIn questo lavoro è stata studiata la risposta
alla disidratazione di tre varietà di olive
(Olea europea sativa Hoffm. and Link).
In particolare, si è verificata l’influenza di
diversi pre-trattamenti sulle cinetiche di disidratazione.
Le olive, dopo la calibratura,
sono state sottoposte a diversi pre-trattamenti,
nell’intento di creare delle microlesioni
superficiali, poi disidratate in un armadio
con aria a flusso ed umidità costanti
alla temperatura di 60°C, disponendo i
frutti delle tesi secondo un piano completamente
randomizzato. Ad intervalli prestabiliti
durante la disidratazione sono
stati effettuati dei prelievi di frutti, al fine
di determinarne le cinetiche.
I risultati mostrano che la tecnica della
scarificatura superficiale ha incrementato
la velocità di disidratazione, mentre gli altri
trattamenti non hanno dato risultati degni
di nota. I frutti disidratati sono stati
giudicati favorevolmente dagli assaggiatori.In this paper, the drying behaviour of three
olive cultivars (Olea europea sativa Hoffm.
and Link), was studied. In particular, the
influence of different pre-treatments on
dehydration kinetics was investigated. Olives
were calibrated and subjected to several
preliminary treatments, in order to
break the peel, before being dehydrated.
Dehydration was carried out at 60°C with
constant flow rate and humidity. Fruits
were placed on trays according to a completely
randomised design. Dehydration
kinetics were computed by weighing fruits
during dehydration. Results show that the
dehydration rate was drastically increased
by piercing the fruit cuticle, while the others
systems did not give appreciable beneficial
effects. Dried olives were appreciated
by panellists

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
