Coprological survey in pet reptiles in Italy
No full textFaecal samples were collected from 324 pet reptiles showing no clinical signs, including 28 saurian species (n=192), three ophidian species (n=74) and three chelonian species (n=58). Samples were examined for the presence of intestinal parasites by direct smear and faecal flotation, while direct immunofluorescence assays were used to reveal the presence of Cryptosporidium oocysts and Giardia cysts. Overall, 57.4 per cent of the reptiles were harbouring intestinal parasites. These included oxyurids (16 per cent), coccidia (12.3 per cent), flagellates (9.3 per cent), strongyles (6.8 per cent), coccidia plus oxyurids (4.9 per cent), coccidia plus flagellates (1.8 per cent), coccidia plus strongyles (1.8 per cent), oxyurids plus strongyles (1.2 per cent), oxyurids plus flagellates (1.2 per cent), Cryptosporidium species (1.2 per cent) and strongyles plus flagellates (0.6 per cent). Intestinal parasites were more prevalent in saurians than in ophidians and chelonians, in insectivores than in carnivores, omnivores and herbivores, and in wild-caught than in captive-born reptiles. A highly significant difference was observed for saurians versus chelonians (odds ratio [OR]=2.20, 95 per cent confidence interval [CI] 1.21 to 3.99), insectivores versus herbivores (OR=2.38, 95 per cent CI 1.26 to 4.49) and in wild-caught versus captive-born pet reptiles (OR=2.36, 95 per cent CI 1.27 to 4.40)
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

Embryonic resorption rates at canine pregnancy diagnoses: A retrospective evaluation
Full text linkPregnancy diagnosis in canines is generally performed during embryonic phase, between 19 and 35 days of gestation. At this stage embryonic resorptions can be observed, which, according to the literature, affects 11-26% of conceptuses and 5-43% of pregnancies. Resorption has been hypothesized as a physiological event in uterine overcrowding, however other factors may be involved, such as infectious or non-infectious diseases. This study aimed to retrospectively evaluate the incidence of embryo resorption at ultrasonographic pregnancy diagnosis in different dog breeds, and to identify the main factors determining the occurrence of the resorption sites. 95 pregnancy diagnoses were performed 21-30 days post-ovulation by ultrasound examination on 74 different animals. Breed, weight, and age of the bitches were recorded, and the reproductive anamnesis was collected from their medical records. The overall pregnancy rate was 91.6%. In 48.3% of pregnancies (42/87), at least one resorption site was visible, and embryonic resorption rate was 14.2% (61 resorption sites/431 total structures). Binary logistic regression showed a significant effect of age (P < 0.001), but not the size of the litter (P = 0.357), nor the size of the mother (P = 0.281) or any previous reproductive problems (P = 0.077). Age was significantly higher in pregnancies with resorptions than in normal ones (60.88 +/- 18.24 and 40.27 +/- 15.74 months, respectively, P < 0.001). The embryonic resorption rate was in line with previous findings, while the incidence of affected pregnancies was higher. Although resorptions may occur physiologically in preg-nancies with large litters, a relationship between embryo resorption and litter size was not identified in our sample group, while aging increased the resorption rates. This, together with the occurrence of repeated embryonic resorptions in some bitches included in the study, suggests how resorptions could also be the result of pathological events. The underlying mechanisms and other factors that may be involved need further clarification.(c) 2023 Published by Elsevier Inc
