Rakugo: la voce come teatro con il maestro Sanyutei Ryuraku
No full textL’arte della narrazione (wagei), in particolare teatrale, ha in Giappone una storia antica e ricca di generi rappresentativi ancora oggi apprezzati e diffusi. Nel wagei è la voce dell’artista a farsi teatro e il pubblico ne gode la capacità di creare immagini, vivificare personaggi, rendere atmosfere, insomma, comunicare emozioni e idee raccontando storie. L’interprete è quasi sempre solo di fronte al proprio pubblico, supportato da pochissimi oggetti scenici e, a volte, da un accompagnamento strumentale. Così è proprio nel rakugo (letteralmente, parole scivolate, lasciate cadere). Di tenore umoristico, sebbene le sue origini possano essere ricondotte ai sermoni buddhisti del X secolo, il genere è noto con questo nome a partire dal XVIII secolo: in precedenza gli attori erano chiamati hanashika (narratore di storie), termine che corrisponde all’odierno rakugoka (interprete di rakugo). Seduto su di un cuscino al centro del palco, il rakugoka racconta storie esilaranti con l’uso di un ventaglio (sensu) e di un piccolo asciugamano rettangolare (tenugui). Le vicende comprendono dialoghi fra più personaggi e per distinguerli l’interprete cambia il tono della voce e ruota il capo in modo allusivo. Le storie, secondo tradizione, sono introdotte da un breve monologo improvvisato e terminano con una battuta finale (ochi) che può non avere rapporto alcuno con la vicenda.
Sanyutei Ryuraku: come in molte altre arti tradizionali giapponesi, anche nel rakugo gli interpreti imparano direttamente dal proprio maestro, senza ricorrere a libri o manuali. Sanyutei Ryuraku, uno dei massimi interpreti viventi di rakugo, entra nella scuola di Sanyutei Enraku all’età di 28 anni. Dopo 6 anni diventa shinuchi (maestro). Ha fatto conoscere la propria arte in numerose tournée che hanno toccato, tra gli altri, Inghilterra, Spagna, Portogallo, Germania e Francia.

Spermatozoon ultrastructure in two species of Amphibolus (Eutardigrada, Eohypsibiidae)
No full textWe examined the ultrastructure of the spermatozoa from two species of eutardigrades, gonochoristic Amphibolus volubilis and hermaphoroditic A. weglarkae, by scanning and transmission electron microscopy. The gametes from the two species were morphologically quite similar, each consisting of a short head, neck and tail. The head included a conic, corkscrew-shaped, bilayered acrosome and a cylindrical nucleus with condensed chromatin. The nucleus is surrounded by cytoplasm organized in ovoid elements with an electron-dense core. The neck is very simple, containing a centriole and unmodified mitochondria. The flagellum contains a 9+2 axoneme and terminates in a tuft of between eight and 10 microtubules. The spermatozoa of Amphibolus, like those of the other eutardigrades, are of the modified type, but nonetheless maintain some primitive aspects of the gametes from heterotardigrades
First SEM studies on tardigrade spermatozoa. Invertebr.
No full textSEM was used to study the external morphology of spermatozoa from two species of Macrobiotus (Eutardigrada). In both species, the spermatozoa consists of 4 parts: (1) a red-shaped acrosome; (2) a helical nucleus; (3) an elongated, swollen middle piece, with lateral vesicles; (4) a tail ending in a tuft of thin and long filaments (probably microtubules). Observations made in vivo and on fresh preparations of sperm cells in toto confirm the images. Moreover, light microscopy findings also showed tahta spermatozoa in the testes and gonoducts have a folded-back acrosomal region, joined to the middle piece. Artificially extracted appeared in some cases straight-headed

Spermatozoan morphology as a character for tardigrade systematics: Comparison with sclerified parts of animals and eggs in eutardigrades
No full textThe male gamete, a cell widely used for evaluating phylogeny in different animal groups, remains relatively unknown in tardigrades. In this paper the spermatozoa of thirteen species of eutardigrades among four genera and three families is evaluated in order to determine whether sperm morphology can be used as a taxonomic character. Spermatozoa of Amphibolus volubilis and A. weglarskae are very similar and this resemblance is congruent with the remarkable similarity of sclerified parts of the species. In addition, the spermatozoa of eight species of the genus Macrobiotus were examined yielding two groups showing strong intragroup similarities. The first group includes M. pseudohufelandi, M. sandrae, M. macrocalix, M. terminalis and M. joannae, and the second M. richtersi, M. areolatus and M. harmsworthi. Again, these groupings were congruent with those determined by analysis of sclerified structures. In contrast, a marked similarity was found between the spermatozoa of Diphascon (Adropion) scoticum and Platicrista angustata, whereas Diphascon (Diphascon) humicus was appreciably different from both species. Resemblances found in this study between spermatozoa and sclerified body parts suggests that the spermatozoa are suitable characters for use in systematic studies

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
