No full textFellini the founder? The Fellini brand in film production
No full textLinking the word ‘entrepreneur’ to Fellini’s name may seem a contradiction. Yet, according to the literature, Fellini was founder, member or manager of no less than three film production companies. Research based on archival material, however, reveals that Fellini never played the role of producer, nor founded a film production company. Thus, the albeit frail aura of Fellini as entrepreneur falls apart. His name seems to have been used by producers as a brand to foster commercial operations. This process starts with La Dolce Vita (1960), which granted Fellini the status of ‘archetypical art film director’ and freed him from producer-imposed obligations. Delving into a mass of various, new archival sources and cross-refer-encing data, this article analyses how the Fellini brand – as auteur versus the film producer’s traditional capitalist logic – was constructed and later exploited by Fellini and his producers

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
In vitro cultures of Actinidia deliciosa (A. Chev) C.F. Liang & A.R. Ferguson: a tool to study the SAR induction of chitosan treatment.
No full textKiwifruit (Actinidia deliciosa (A. Chev.) C.F.
Liang & A.R. Ferguson), a profitable crop with a steady
growth in export, should be certainly preserved from the
most common diseases. Kiwi plants were strengthened
with a natural compound, the chitosan, a well-known
elicitor of Systemic Acquired Resistance (SAR), to
study and evaluate the interaction between this compound
and in vitro cultures, in order to propose a possible
alternative to reduce the number of chemical pesticide
treatments in the prevention of disease outbreak. To
detect the effectiveness in eliciting SAR, the effects 15
and 50 mg/L of chitosan on kiwi micropropagated
plants were tested at the in vitro multiplication stage.
Different biochemical markers were measured, like phenols
and several enzymes involved in defence response,
i.e. guaiacol-peroxidase (G-POD), ascorbate peroxidase
(APX), phenylalanine ammonia lyase (PAL) and polyphenol
oxidase (PPO). The beneficial growth effect was
also evaluated measuring the dry biomass and the total
soluble protein content of treated plants. The systemic
disease protection elicited by chitosan has been detected
thanks to its ability to enhance the activity of enzymes
involved in detoxification processes (G-POD and APX)
and in increasing plant defence barriers (PAL and PPO).
In addition, chitosan treatment increased both dry biomass
and protein contents demonstrating a general enhancement
of plant fitness
