Observations on some haematic parameters during the laying period of the Muscovy duck.
No full textThe aim of this research was to study the relation between several haematic parameters and oviposition (egg laying intensity) in Muscovy ducks of the white variety. Ca, P, Mg, total cholesterol, triglyceride, glucose, total protein, albumin, globulin were studied. Total protein, albumin, globulin, calcium, phosphorus, showed positive correlations with egg laying intensity, specially high for the last 3 traits. This means an increase of phosphoprotein with the egg laying intensity. Total cholesterol and glucose showed no correlation with ovodeposition
The Aymand's hernia. Case report and review of the literature
No full textThe crural hernia containing an inflamed appendix is a rare entity and must be considered a variant of the hernia first described in 1735 by Claudius Amyand.
This hernia is rarely recognised and diagnosed before the surgical treatment because it is often confused with a stran- gled hernia.
In spite of this, the clinical presentation seems to follow a well determined pathway, so is possible to argue that the uncorrect diagnosis is to be attributed to the ignorance of this hernia.
We report a case of Amyand’s crural hernia in a woman 57 years old. The base of the appendix was not inflamed and, according to this, we made an appendectomy. We closed the hernia defect without the use of a synthetic mesh. The post operative period was regular and free of complications

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
