No full textObjective: To contribute to the understanding of colorectal neoplasms with the personal clinical experience of five years,
and to compare it with the current literature.
Material and methods: Twenty five primary tumors of the colon and rectum have been diagnosed in 12 dogs and 13 cats
in our clinic from January 1999 to December 2003. The histopathologic diagnosis has been obtained by endoscopic biopsy
in 8 cases, ultrasound-guided biopsy in 12 cases and laparotomic biopsy in 5 cases. Only benign and malignant primary
tumors of the colon and rectum have been included in the study (secondary intestinal multicentric tumors and metastatic
tumors were not included).
Results: Twenty five tumors of the colon and rectum have been found in 12 dogs and 13 cats. The following neoplasms
were diagnosed in the dog: one rectal adenomatous polyp with malignant tranformation of the pedicle, 2 rectal adenomatous
polyps, 3 rectal adenocarcinomas, one colonic adenocarcinomas, 2 rectal leiomyosarcomas, 2 colonic lymphomas
and one cecal fibrosarcoma. In the cat, 11 out of 13 lymphomas were localised in the colon, one in the ileocecocolic junction,
and one in the rectum.
Conclusion: Our clinical data are similar to those reported in literature. In the dog, all benign epithelial neoplasms of the
rectum were polypoid; one polyp showed malignant transformation. Among malignant epithelial neoplasms of the colon
and rectum, 2 out of 3 cases were observed in predisposed breeds. The most common sarcoma was leiomyosarcoma. A
cecal fibrosarcoma was also observed, a rare neoplastic type in the bowel and apparently never reported in this site. All
neoplasms observed in cats were lymphomas, the most common tumors of the colon and rectum in this species. Unlike
the dog, no epithelial neoplasia were observed in the cat

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

No full textAppropriate 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
