First spaceborne observation of sea surface height using GPS-reflectometry
No full textAn analysis of spaceborne Global Positioning System reflectometry (GPS-R) data from the TechDemoSat-1 (TDS-1) satellite is carried out to image the ocean sea surface height (SSH). An SSH estimation algorithm is applied to GPS-R delay waveforms over two regions in the South Atlantic and the North Pacific. Estimates made from TDS-1 overpasses during a 6?month period are aggregated to produce SSH maps of the two regions. The maps generally agree with the global DTU10 mean sea surface height. The GPS-R instrument is designed to make bistatic measurements of radar cross section for ocean wind observations, and its altimetric performance is not optimized. The differences observed between measured and DTU10 SSH can be attributed to limitations with the GPS-R instrument and the lack of precision orbit determination by the TDS-1 platform. These results represent the first observations of SSH by a spaceborne GPS-R instrument
Erratum: Lack of immunity against rubella among Italian young adults. [BMC Infect Dis., 17, (2017) (199)] Doi: 10.1186/s12879-017-2295-y
No full textAfter publication of this article [1], the authors noted that the given names and family names of all authors had been inverted, and are therefore incorrect in the original article. In the original article, the author names appear as the following: Gallone Maria Serena, Gallone Maria Filomena, Larocca Angela Maria Vittoria, Germinario Cinzia and Tafuri Silvio. However, this is incorrect, and the author names should appear as per the below: Maria Serena Gallone, Maria Filomena Gallone, Angela Maria Vittoria Larocca, Cinzia Germinario, Silvio Tafuri. The author names have been corrected in the author list and the citation for this Erratum
La paternità dell'opera
No full textThis paper considers the several hypotheses advanced by modern scholars on the authorship of [Xenophon]’s Constitution of Athens. Many scholars have tried to identify the author of this work with members of the cultural elite – among whom the historians Xenophon and Thucydides, and the sophists Antiphon and Critias –, or with politicians such as Thucydides son of Melesias, Phrynichus, Cleon, and more recently Andocides (with regard to the history of classical scholarship, it is worth noting that all the aforesaid stances (with the only exception of the last one) had already been proposed by 19th century scholars). However, no one of these attributions can be strictly demonstrated, although Andocides’ name, recently suggested by Ramirez Vidal, opens new interesting perspectives for further research. The difficulty in finding a satisfactory solution to the issue of authorship explains why some modern scholars prefer to regard the work as anonymous
Elisabetta I come Cinzia: Una regina e il suo oceano
No full textThe defeat of the Spanish Armada in the Channel in 1588 turned ‘a weak and feeble woman’ into one of the most relevant characters of late 16th-century European history: Elizabeth I, the Tudor Queen, was considered a semi-divine creature whom the myth, by comparing her to Moon goddesses like Diana and Cinthia, had made known as Semper Eadem.
The identification of the queen with Cinthia became more and more evident after the events occurred in 1588, when she was hailed as the moon goddess par excellence in a series of texts written by her contemporaries. It was in that period, the last decades of the 16th century, that Sir Walter Ralegh, courtier, poet and seaman, wrote The Poems to Cynthia: a collection of short poems where Elizabeth I, the lady of the seas, is addressed as his beloved. The role of Elizabeth as Cinthia is evident above all in Ralegh’s Last Book of the Ocean to Cynthia, an unfinished poem where the author, desperate for being in disgrace, appeals to her clemency and addresses her as the empress of the ocean.La sconfitta della flotta spagnola nelle acque della Manica nel 1588 trasformò una donna sola e fragile in una delle figure più rilevanti della storia europea di fine XVI secolo: Elisabetta I Tudor divenne per i suoi sudditi una creatura semidivina che il mito, accostandola alle divinità lunari Diana e Cinzia, avrebbe consegnato alla Storia come Semper Eadem.
Pur essendo evidente già nei primi tempi del suo regno, l’identificazione della sovrana con Cinzia, la dea che governa i mari e i corsi d’acqua, si fa ancora più evidente dopo il 1588, quando si assiste ad una fioritura di testi che esaltano Elisabetta I come la dea lunare per eccellenza.
Sempre in quegli anni di fine XVI secolo, Sir Walter Ralegh compone The Poems to Cynthia: letterato, cortigiano e uomo di mare, Ralegh dedicherà il suo amore ad Elisabetta come Cinzia, signora dei mari. Il legame tra Elisabetta e l’oceano è soprattutto evidente in Last Book of the Ocean to Cynthia, un poemetto incompiuto in cui il poeta, caduto in disgrazia, riunisce sotto il nome di Cinzia, la donna e la regina, l’amante e la dea, trasformando così Elisabetta in dea e imperatrice dei mari

Regole della concorrenza e tutela della forza lavoro: il (fragile?) schermo della community
No full textThe essay analyzes some of the changes that we commonly label “sharing economy”, with particular respect to the “gig economy” , corresponding to the so named – depending on the case – “work on demand via app” or “crowdwork”. In the first part of the study, the author focuses on its implications on competition law, regarding the Italian legislation and case law as well as the position of the European Court of Justice. The analysis, completed by the comparison with other European countries’ case law, shows that the mere existence of a platform that enables service providers to connect with their clients does not justify the disapplication of the legislation that regulates a particular service. Otherwise, the behavior of the platform would be qualified as unfair competition. In the second part, the author moves on the questions concerning labor law and workers protection. In case the platform is conceived as the one which organizes and profits from a certain service – that is, an economic subject (that must apply the law as all other employers do) and not a mere marketplace – this might imply the application of labor law protections. The problem is often to prove before the Court that the parties established a stable working relationship, which puts the one who provides the service (required via app) under the authority of the platform. The author shows how the different legal systems may comply with the difficulties to define the employment relationships in the contest of the current digital era

Lev Tolstoj v Italii
No full textThe author of the article describes two trips to Italy made by Leo
Tolstoy in 1857 and 1860–1861, and for the first time publishes her own translation from Italian into Russian of the text appearing in the pamphlet “Three Popes, or Peace Between Christian Churches” (I tre papi, ossia la pace tra le chiese cristiane, 1893) as a report by L.N. Tolstoy at the “Conference on the fusion of all Christian churches” (held supposedly in 1891, in Florence). She also publishes three letters sent to Tolstoy by the author of the pamphlet, Giovanni Guidotti, recently discovered
in the Department of Manuscript Funds of the State Museum of L.N. Tolstoy, which demonstrate that Tolstoy never attended the aforementioned conference and that Guidotti’s book is a historical forgery
