Spread and Habitat Selection of Chrysomya albiceps (Wiedemann) (Diptera calliphoridae) in Northern Italy: Forensic Implications
No full textHabitat selection exploited by Chrysomya albiceps during its initial spread in Northern Italy was analyzed in relation to landscape
structure. The results of two short studies and a case report are here discussed. C. albiceps was not found on experimental pig carcasses in the urban area of Pavia. It was missing in the woody mountains surrounding Lecco, but it was found in the same area, at a lower altitude, within the typical ‘‘urban sprawl’’ landscape. It was then recorded in a natural reserve, among a rich carrion-fly population. Indications coming from habitat selection suggest that C. albiceps has not yet saturated its potential ecological niche in newly colonized areas of Northern Italy. Factors like temperature,
altitude, and interspecific competition can act as limiting factors, affecting habitat selection and distribution in newly colonized areas; the influence of those factors has to be taken into account for forensic purposes
Inibitori dell’aromatasi nel trattamento dell’endometriosi profonda
No full textRecent case reports and pilot studies suggested that aromatase inhibitors might be effective in treating pain symptoms related to the presence of endometriosis. We present the case of a 32-year-old woman who suffered dysmenorrhea, dyspareunia, chronic pelvic pain, and dyschezia caused by rectovaginal endometriosis. Pain symptoms recurred after treatment with the oral contraceptive pill; the patient refused surgery.Therefore a double-drug regimen including letrozole (2.5 mg/day) and norethisterone acetate (2.5 mg/day) was offered to the patient. The scheduled length of treatment was six months. This double-drug regimen determined a quick and significant improvement in all pain symptoms. During treatment, the patient complained mild arthralgia. After the interruption of treatment, pain symptoms quickly recurred and at 6-month follow-up their intensity was similar to baseline values. Operative laparoscopy was performed, the presence of rectovaginal endometriosis was confirmed and all visible endometriotic lesions were excised. Aromatase inhibitors might be offered when pain symptoms caused by endometriosis persist during the administration of other hormonal therapies and the patient refuses surgery. However, women must be informed that these drugs determine only a temporary relief of pain symptoms and might cause adverse effects (such as arthralgia)

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
Preoperative evaluation of an appendiceal mucocele in a woman with endometriosis
No full textAppendiceal mucocele is a rare cause of pain in the right lower abdominal quadrant. This case report describes a case of coexistence of endometriosis and appendiceal mucocele, which were diagnosed preoperatively by computed tomography, magnetic resonance imaging and ultrasonography. Laparoscopic excision of the appendiceal mucocele and endometriosis resulted in the disappearance of the symptoms. © 2013 Wichtig Editore
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
