Phylogeography of a marine insular endemic in the Atlantic Macaronesia : the Azorean barnacle, Megabalanus azoricus (Pilsbry,1916)

[EN]The Azorean barnacle, Megabalanus azoricus (Pilsbry, 1916), is a Macaronesian endemic whose obscure taxonomy and the unknown relationships among forms inhabiting isolated Northern Atlantic oceanic islands is investigated by means of molecular analysis herein. Mitochondrial data from the 16S rRNA and COX1 genes support its current species status, tropical ancestry, and the taxonomic homogeneity throughout its distribution range. In contrast, at the intraspecific level and based on control region sequences, we detected an overall low level of genetic diversity and three divergent lineages. The haplogroups α and γ were sampled in the Azores, Madeira, Canary, and Cabo Verde archipelagos; whereas haplogroup β was absent from Cabo Verde

La carriera degli attori italiani di prosa dalla scena allo schermo (1909-1916)

Most actors of the Italian silent cinema in the early 1910s have a theatrical training. Some of them are already asserted or famous actors (like Cesare Dondini, Ermete Novelli, Ermete Zacconi, Giovanni Grasso) who are invited “to pose” for the cinema following their reputation, according to a strategy of an aesthetic and cultural legitimacy launched in 1909 by film d'art of the Pathé Consortium. I think it is the proverbial readiness and strength of the stage Italian actors that create a decisive contribution to the rapid development of the national cinema industry, despite its serious structural deficiencies, from the protoindustrialized phase (1909) to the golden age of divismo (starting in 1913), until the first signs of decadence (1919), and the so-called “fall” of the UCI production and distribution system. This is the main topic of the thesis: an investigation on the Italian stage actors engaged in the film industry (“from stage to screen” as the Italian title says, but in a “post-Vardac” approach) through many different sources: periodicals, memories, personal and business letters, and also contracts, found in several archive funds. A specific chapter is dedicated to the artistic career of Febo Mari (1881-1939), real name Alfredo Rodriguez, witch is a time-sample symptomatic of deep ties established between the growing film publishing and the Italian theatrical production system in the 1910s. The Mari debut in cinema and his ascent toward screen “divo” status coincides with the parable that leads from emergence to decadence of divismo in Italy.

"the easter rising of 1916: A step towards the independence of ireland analysed through the works of irish writers."

The 1916 Easter Rising, an unsuccessful insurrection which resulted in the Irish War of Independence, generated a deep change in the political landscape in Ireland. The purpose of this work is to describe this crucial period in the history of Ireland through the voices of Irish writers who expressed their ideas and feelings about the way Ireland was close to gaining its independence. Thanks to songs, poems and literature, I analysed the events of that period through the eyes of the Irish people. Authors like Roddy Doyle and William Butler Yeats were fundamental in examining this topic very thoroughly. Through their works, they were able to convey their knowledge about the events of those years and, at the same time, to give their own opinion, as Irish people, on the topic.

Body mass index, hormone replacement therapy, and endometrial cancer risk: a meta-analysis

Background: Body mass index (BMI) is a risk factor for endometrial cancer. We quantified the risk and investigated whether the association differed by use of hormone replacement therapy (HRT), menopausal status, and histologic type. Methods: We searched MEDLINE and EMBASE (1966 to December 2009) to identify prospective studies of BMI and incident endometrial cancer. We did random-effects meta-analyses, meta-regressions, and generalized least square regressions for trend estimations assuming linear, and piecewise linear, relationships. Results: Twenty-four studies (17,710 cases) were analyzed; 9 studies contributed to analyses by HRT, menopausal status, or histologic type, all published since 2003. In the linear model, the overall risk ratio (RR) per 5 kg/m2 increase in BMI was 1.60 (95% CI, 1.52–1.68), P < 0.0001. In the piecewise model, RRs compared with a normal BMI were 1.22 (1.19–1.24), 2.09 (1.94–2.26), 4.36 (3.75–5.10), and 9.11 (7.26–11.51) for BMIs of 27, 32, 37, and 42 kg/m2, respectively. The association was stronger in never HRT users than in ever users: RRs were 1.90 (1.57–2.31) and 1.18 (95% CI, 1.06–1.31) with P for interaction ¼ 0.003. In the piecewise model, the RR in never users was 20.70 (8.28–51.84) at BMI 42 kg/m2, compared with never users at normal BMI. The association was not affected by menopausal status (P ¼ 0.34) or histologic type (P ¼ 0.26). Conclusions: HRT use modifies the BMI-endometrial cancer risk association. Impact: These findings support the hypothesis that hyperestrogenia is an important mechanism underlying the BMI-endometrial cancer association, whilst the presence of residual risk in HRT users points to the role of additional systems.

Natural History on Blocks, in Bodies, and on the Hearth: Juvenile Science Literature and Games, 1850-1875.

This article examines the role of domestic spaces and images in mid-nineteenth-century science writing for children. Analyses of John Mill’s The Fossil Spirit, A.L.O.E.’s Fairy Frisket, John Cargill Brough’s The Fairy Tales of Science, Annie Carey’s “Autobiography of a Lump of Coal,” and an assortment of boxed games reveal a variety of ways in which overwhelming scientific concepts are domesticated. Moreover, juvenile science literature contributes this appeasing domestication to the broader scientific discourse, consistently framing natural history in terms of human experience.
