Recent Perceptions of Rural Australia in Italian and Italian Australian Narrative
No full textItalian settlement in rural and outback areas of Australia during the late 1800s and early 1900s has remained a largely unsung saga while most Italians migrating to Australia after 1947 ultimately settled in urban areas. Few narrative writers have written about non-urban Australia in substantially social realist terms. More recently, this trend had taken a post-modern perspective in a few Italian Australian and Italian writers who depict the Australian outback as providing a solution to the protagonists' life quest and promote a discourse on nature as a dynamic, positive and vital element that contrasts with man's static negativism
Rallus adolfocaesaris Alcover, Pieper, Pereira & Rando, 2015, n. sp.
No full textRallus adolfocaesaris Rallus adolfocaesaris n. sp. forms with the rails from Pico, Graciosa, Terceira and Santa Maria, a Macaronesian group of species that share the display of legs less robust and wings less reduced than R. lowei n. sp. The humerus of R. adolfocaesaris n. sp. is slightly more gracile than in R. aquaticus, but considerably wider than in R. lowei n. sp.. Its size (c. 33 mm in length) is similar to that of the Pico rail, and much larger than the São Miguel rail (20 %) and São Jorge (31 %) rails. The smaller humerus in relation to R. aquaticus suggests a shortening of the primary remiges, although this reduction was probably not so extreme as in R. lowei n. sp. The hindlimb bones are gracile compared to R. lowei n. sp., and short in relation to R. aquaticus. R. adolfocaesaris n. sp. has a femur close in length to those of R. lowei n. sp., and slightly longer than in the rails of São Miguel, Terceira and Pico, but shorter than in R. aquaticus (7 %) and longer than in R. minutus n. sp. (28 %, see Figure 15). Its tibiotarsus is slightly shorter than in R. lowei n. sp., R. carvaoensis n. sp. and R. montivagorum n. sp., shorter than in R. aquaticus (19 %) and longer than in R. minutus n. sp. (11 %, Table 1 & Figure 16). The ANOVA performed on the tibiotarsus distal width (trait 25) identified significant morphological differences (F4,84= 8.872; p <0.001) between R. adolfocaesaris n. sp. and R. carvaoensis n. sp. (p = 0.007) and R. minutus n. sp. (p = 0.002) but not with R. montivagorum n. sp. (p = 0.262) and R. aquaticus (p = 0.504). R. adolfocaesaris n. sp. has a similar tarsometatarsus length (U = - 0.342; p = 0.833) but a smaller tarsometatarsus distal (U = - 2.449; p = 0.012) and proximal width (U = - 2.646; p = 0.006) than R. lowei n. sp. The tarsometatarsus is shorter (20 %) than in R. aquaticus (U = - 2.838; p <0.001), and longer (25 %, U = - 2.236; p = 0.0.36) than in R. minutus n. sp. No differences were detected in tarsometarsus proximal (U = - 1.492; p = 0.171) and distal widths (U = - 1.167; p = 0.262) between R. adolfocaesaris n. sp. and R. minutus n. sp. Seemingly, the ANOVA did not detect any relevant difference in tarsometatarsus length, and proximal and distal widths between R. adolfocaesaris n. sp. and the rails of São Miguel and Pico. The ratio of humerus-to-femur length ratio (0.85) suggests that R. adolfocaesaris n. sp. was a flightless bird. According to this figure, and since the hindlimb bones are thinner than in R. lowei n. sp., the loss of the flying capacity should have been less extreme in R. adolfocaesaris than in the Madeiran rail. The short stout tarsometatarsus (relative to the femur) suggests that R. adolfocaesaris n. sp. could be a slow-pace runner.Published as part of Alcover, Josep Antoni, Pieper, Harald, Pereira, Fernando & Rando, Juan Carlos, 2015, Five new extinct species of rails (Aves: Gruiformes: Rallidae) from the Macaronesian Islands (North Atlantic Ocean), pp. 151-190 in Zootaxa 4057 (2) on page 180, DOI: 10.11646/zootaxa.4057.2.1, http://zenodo.org/record/23359

A species of Rallus that is overall smaller and stouter than R. aquaticus, and notably larger than R. carvaoensis n. sp. from São Miguel and R. minutus n. sp. from São Jorge. This species combines relatively smaller wing bones (humerus and ulna) with massive leg bones (mainly tarsometatarsus) and a wider synsacrum than R. aquaticus and R. montivagorum n. sp. The available wing bones are smaller than in R. montivagorum n. sp. and R. adolfocaesaris n. sp., and larger than in R. carvaoensis n. sp. and R. minutus n. sp. The femur and tibiotarsus are only slightly shorter than those of R. aquaticus, the tarsometatarsus being the most reduced leg bone. The distal leg bones (tibiotarsus and tarsometatarsus) are more robust than their counterparts in the other species of Rallus described herein (especially compared with the neighbouring Porto Santo rail), except for R. minutus n. sp. from São Jorge. [Figures 2, 15 A, 16 A, 17 A; Table 1] Etymology. The specific name honours Richard Thomas Lowe, who during his time in Madeira was an assiduous student of the flora and fauna (mainly fishes and molluscs) of the archipelago and who published many important books and articles (da Silva and de Meneses 1984). He was born 4 Dec 1802 in Findern, Derbyshire (England). After finishing school and theological studies, he visited Madeira for the first in 1828 and became an Anglican chaplain on the island in 1832. Later on, he returned to England and lived in Lea, Lincolnshire. He returned to Madeira several times, the last one in April 1874 from Liverpool, but he was shipwrecked soon after setting out and drowned, together with his wife, southwest of the Scilly Islands. In one of his publications (Lowe 1853) he mentioned for the first time the discovery of (sub)fossil lizard and bird bones. Richard Owen, who studied the material, could not identify the bones of the three species found, but could only give their size as similar to that of "gull or crow,” " thrush" and "sparrow".Published as part of Alcover, Josep Antoni, Pieper, Harald, Pereira, Fernando & Rando, Juan Carlos, 2015, Five new extinct species of rails (Aves: Gruiformes: Rallidae) from the Macaronesian Islands (North Atlantic Ocean), pp. 151-190 in Zootaxa 4057 (2) on pages 155-157, DOI: 10.11646/zootaxa.4057.2.1, http://zenodo.org/record/23359
Rallus carvaoensis Alcover, Pieper, Pereira & Rando, 2015, n. sp.
No full textRallus carvaoensis R. carvaoensis n. sp. belongs to the group of species that combine robust leg bones (in this case, excluding the femur) with reduced wings. It is smaller than R. lowei n. sp. from Madeira and larger than R. minutus n. sp. from São Jorge. Although no complete skulls are available, the premaxilla is longer and more curved than in R. aquaticus and R. montivagorum n. sp. (see Figure 8 B–E). The bill shape was probably similar to that of R. minutus n. sp. R. carvaoensis n. sp. has a shorter coracoid and humerus than R. montivagorum n. sp. from Pico (12 % and 19 % shorter, respectively; U = - 2.448; p = 0.007, U = - 2.714; p = 0.002) and R. aquaticus (26 % and 29 % shorter, respectively; U = - 2.833; p <0.001, U = - 2.842; p <0.001). The available forelimb bones (humerus and carpometacarpus) are around 30 % smaller than in R. aquaticus, while the femur, tibiotarsus and tarsometatarsus are 12 %, 17 % and 26 % smaller than in R. aquaticus, respectively. The humerus is longer (9 %) than in R. minutus n. sp. The carpometacarpus is smaller than in the Pico rail (21 %) and in R. aquaticus (30 %) (Table 1), and it is longer than in R. minutus n. sp. (35 %). Despite all the known ulnae being incomplete, its extreme reduction in size is clear based on their width measurements (see Table 1). The femur length of R. carvaoensis n. sp. is close to R. lowei n. sp. and R. adolfocaesaris n.sp (Table 1). The ANOVA of femur length (trait 17) of the Rallus from São Miguel, Pico, and R. aquaticus, reveal significant differences among them (F2,66 = 75,664; p <0.001). These differences were significant between R. carvaoensis n. sp. and R. aquaticus (p <0.001) (12 %), but not between R. carvaoensis n. sp and the Rallus from Pico (p = 0.601). The tibiotarsus of R. carvaoensis n. sp. is longer than in R. minutus n. sp. (14 %), slightly longer than in R. adolfocaesaris n. sp., close in length to R. lowei n. sp. and the Rallus from Pico, and smaller (17 %) than in R. aquaticus. The ANOVA of the tibiotarsus distal width (trait 25) identified morphological differences between R. carvaoensis n. sp. and R. adolfocaesaris n. sp. (p = 0.007), R. aquaticus (p <0.001), and R. minutus n. sp. (p = 0.002), but not with Rallus montivagorum n. sp. (p = 0.262). The MANOVA of tarsometatarsus lengths (total length and distal width; traits 26 and 29) showed that R. carvaoensis n. sp. has a shorter tarsometatarsus than in R. lowei n. sp. (11 %) (p = 0.003), R. montivagorum n. sp. (11 %) (p <0.001), and R. aquaticus (26 %) (p <0.001), but it is longer than in R. minutus n. sp. (p <0.001). The tarsometatarsus distal width of R. carvaoensis n. sp. is shorter than in R. lowei n. sp. (p <0.001) and R. aquaticus (p <0.001), but similar to R. montivagorum n. sp. (p = 0.795) and R. minutus n. sp. (p = 0.871). The length and distal width of the tarsometatarsus of R. carvaoensis n. sp. is similar to R. adolfocaesaris n. sp. (U = - 1,837; p = 0.085, U = - 1,829; p = 0.067), whereas its proximal width is narrower than in R. lowei n. sp. (U = 3.337; p <0.001), but similar to R. adolfocaesaris n. sp. (U = - 0,155; p = 0.94), R. montivagorum n. sp. (U = - 0,907; p = 0.388), R. minutus n. sp. (U = - 1.533; p = 0.145) and R. aquaticus (U = - 1,911; p = 0.057). The leg bones of R. carvaoensis n. sp. indicate that it was more stout than Rallus aquaticus. The low humerusto-femur length ratio (0.76) –the smallest among all the species here described—is clearly indicative of flightlessness. The short stout tarsometatarsus (relative to the femur) suggests that R. carvaoensis n. sp. could be a slow-pace runnerPublished as part of Alcover, Josep Antoni, Pieper, Harald, Pereira, Fernando & Rando, Juan Carlos, 2015, Five new extinct species of rails (Aves: Gruiformes: Rallidae) from the Macaronesian Islands (North Atlantic Ocean), pp. 151-190 in Zootaxa 4057 (2) on page 181, DOI: 10.11646/zootaxa.4057.2.1, http://zenodo.org/record/23359

Measurements of paratypes: see Table 1. Age: Probably Holocene-Recent. Diagnosis. A very small species of Rallus. It is smaller than any other rail from Macaronesia and markedly smaller than R. aquaticus. The wing bones are relatively more reduced than in any other Azorean rail, including the São Miguel rail. The bill is very elongated and slightly curved. The humerus has a reduced fossa pneumotricipitalis, the crista bicipitalis is less expanded than in R. aquaticus, and has a reduced and relatively flattened caput. All the bones, especially ulna, carpometacarpus and tarsometatarsus are very reduced in size relative to R. aquaticus (Figures 12, 13 and 17). The tarsometatarsus is relatively stout (Figure 17). The synsacrum (Figure 14) is very broad, and the sternum (Figure 10) presents a very reduced depth to the carina sterni (the most reduced carina recorded among the species described herein). Etymology. from the Latin, meaning little.Published as part of Alcover, Josep Antoni, Pieper, Harald, Pereira, Fernando & Rando, Juan Carlos, 2015, Five new extinct species of rails (Aves: Gruiformes: Rallidae) from the Macaronesian Islands (North Atlantic Ocean), pp. 151-190 in Zootaxa 4057 (2) on pages 168-171, DOI: 10.11646/zootaxa.4057.2.1, http://zenodo.org/record/23359

E-ASTROGAM: A space mission for MeV-GeV gamma-ray astrophysics
No full texte-ASTROGAM is an observatory space mission dedicated to the study of the gamma radiation in the range from 0.3 MeV to 3 GeV. The detector is composed by a Silicon tracker, a calorimeter, and an anticoincidence system. The mission is based on an advanced space-proven detector technology, with unprecedented sensitivity, angular and energy resolution, combined with polarimetric capability. Thanks to its performance in the MeV-GeV domain, substantially improving its predecessors, eASTROGAM will open a new window on the non-thermal Universe. In particular it will determine the origin of key isotopes fundamental for the understanding of supernova explosions and the chemical evolution of our Galaxy. It will also shed light on the processes behind the acceleration of cosmic rays in our Galaxy

No full textOn the occasion of the 100th issue of the „Quellen und Forschungen aus
italienischen Archiven und Bibliotheken“, the article offers a retrospective look at the
journal, with a focus on the medieval section. It highlights the presentation or edition
of Vatican sources, both as a reflection of the Institute’s research and as a constant distinctive feature in the context of international journals. At the same time, the author
stresses the journal’s openness to new topics following trends in medieval studies,
alongside well-established issues, and the increasingly intense internationalisation
resulting from collaboration with other researchers and institutes based in Rome, Italy
and abroad. Finally, it expresses the hope that the journal may continue to be a means
of fostering research on primary sources, especially in the context of the Repertorium
