Reapeted Ovum Pick-up in Italian Mediterranean Buffalo cows
No full textThe potential of the ovum pick-up technique, used over a long period, was evaluated in 6 Italian Mediterranean buffalo cows that had more than 500 d open. The cows were submitted to ovum pick-up twice weekly for 2 mo. An additional 2-mo cycle of ovum pick-up was performed in 3 of the buffalo. The ovum pick-up sampling did not affect the resumption of reproductive activity of these animals. In fact, all the buffalo conceived, on average, 47.5 ± 27.5 d after the last ovum pick-up. An average of 5.48 follicles was punctured, and 2.71 oocytes were collected per session. However, only 53.5% of these oocytes were suitable for in vitro embryo production. The number of punctured follicles differed between individual cows. There were no differences in the number of collected oocytes or in the recovery rates. The number of punctured follicles, the number of collected oocytes and the recovery rate were similar in the first and second months; the quality of the oocytes was, however, better in the second than in the first month (P < 0.05). The increasing interval between 2 consecutive ovum pick-up sampling (intersession interval) caused an increase of the percentage of large follicles. Moreover, the increase of the intersession interval from 4 to 5 d decreased the quality of the collected oocytes (P < 0.05). The efficiency of in vitro production of embryos to expanded blastocysts was 16.7%

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
