No full textTwo new human cases of dirofilariasis in Sardinia
No full textTwo new human cases of dirofilariasis, both due to Dirofilaria (Nochtiella) repens, recently occurring in Nuoro province (Sardinia) on people permanently resident in the island, are described. The parasite was located in one case into the uterine round ligament, in the other it was subconjunctival. Some observations about the diagnostic difficulties in the first one and the dramatic symptoms in the second, whose parasite was yet alive during the surgical ablaction, are discussed. These cases are the 9th and the 10th, respectively, reported in man in Sardinia, but it is possible that other cases are undiagnosed and consequently are not published

Abstract
Hepatic hydatidosis is still now a frequently observed pathology and the total pericistectomy, for surgical difficulties, often request a subtotal pericistectomy with complications such as biliary fistula, haemorrhage and subphrenic abscesses. The Authors reconsidered their hepatic hydatidosis cases to evaluate the indication to the surgery that in their opinion, should have to consider first of all the functional state of the cysts. Infact, only the vital and the fertil ones, less frequent even if rarely found, should have indications to the surgery, because more likely complicated. The dead and steril ones, instead being asymptomatic, should go under periodic control, since destined to degeneration and calcification. Are also compared the pre-surgery data with the parasitologic exam, to evaluate ETG reliability to determine the functional state of the cyst. Twenty one cysts out of 76 were operated correctly because vital/fertile and in 19 of these the ultrasound indications were correct (90.5%). 55 didn't have indications to the surgery since dead/steril and for 51 (92.7%) the ultrasound indication was correct. So we can say that morphological ultrasound data permitted a correct surgery indication for 70 cyst's on their functional state (93.4% of total). In this way the post-operative complication were reduced of 5%. The Authors found morphologic and/or functional ultrasound error for 6 cysts (7.9%), and in only 3 cases (3.9%) the error were both morphological and functional Infact we believe that a ultrasound morphologic classification should have a functional corrispective for the surgical indication So only the unilocular and multivescicular cysts, vital and fertil one, should have indication to the surgery. On the contrary the solid ones should have an ultrasound follow up and treated by chemotherapy if necessary.

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
