Carlo Magri e il suo contributo al teatro barocco maltese
Full text linkThe paper, titled “Carlo Magri e il suo contributo al teatro barocco”, presents an in depth study and analysis of the Maltese playwright's theatrical works in the seventeenth century and his contribution to Baroque theatre in the Mediterranean region. The study focuses on his 2 three-act plays written under the pseudonym of ‘Marco Largi, maltese’. The first one entitled La regia è un Sogno ovvero la Costanza, written in 1672, was the first play written by a Maltese ever to be published. The second one, written in 1674, was entitled Chi la dura la vince, ovvero Teodolinda. The author compares and contrasts themes, settings and other aspects of Magri's play with those of Sicilian and Neapolitan dramatists like Tommaso Aversa and Niccolo` Amenta, amongst others. Even though Maltese theatrical works of the period have been influenced by Italian baroque theatre, particularly by the Neapolitan commedia dell'arte style of writing and rep-resentation, the study reveals how Carlo Magri succeeded in introducing in his play a number of innovations. One of the most important is the elimination, as a result of his sensitivity to the public's wishes, of the use of vulgar language and of the prologue. This delineates him as a pioneer in the drive for change.peer-reviewe
An ADPase from sarcoplasmic reticulum of rabbit muscle cleaves ADP bound to F-actin
No full text1.1. We have found that sarcoplasmic reticulum from rabbit muscle contains an ADPase which cleaves ADP bound to F-actin.
2.2. The interaction is not of the simple Michaelis-Menten type, the order of the reaction being larger than the first.
3.3. A possible explanation of this behaviour could be that ADPase binds to two adjacent actin monomers with a preferred orientation thus cleaving preferentially the nucleotide of one of the two monomers
Actin modifying system of the sarcoplasmic reticulum from rabbit muscle
No full textBy interaction with sarcoplasmic reticulum from rabbit muscle G-actin loses the capability to polymerize. The modification of actin is due to the concomitant action of the Ca2+ ATPase and of an ADPase embedded in the sarcoplasmic reticulum vesicles. Methyl isobutyl xanthine increases the rate of modification of actin by the sarcoplasmic reticulum vesicles by increasing the rate of the exchange of the actin-bound nucleotide
The rate-limiting step of the protamine-induced adenosine triphosphatase activity of adenosine triphosphate-G-actin

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
