No full text[EN] Tourists are increasingly involved in co-creating attractions’ symbolic images, sharing their experiences and opinions on websites like TripAdvisor and other similar rating and review platforms. In this paper, we propose a strategy for analyzing people’ opinions about tourist points of interest, using an Ambient Geographic Information approach to georeference the polarity scores of reviews. Visualizing these scores on a map can be used to obtain helpful information for implementing strategic actions and policies of institutional and business actors involved in the tourist industry, as well as to help users plan their future experiences. A case study concerning the reviews of the restaurants in Naples (Italy) shows the effectiveness of the proposal.Celardo, L.; Misuraca, M.; Spano, M. (2023).

Giovanni Spano e gli ebrei. Due mss. ebraici della sua collezione nella Biblioteca Universitaria di Cagliari e nuove scoperte sulla Sardegna Judaica
No full textIn the first part of this study the author examines the attitude of Giovanni Spano (1803-1878), a learned ecclesiastical scholar in Sardinia during the 19th century, towards the Jews and Judaism, as it appears from his “History of the Jews in Sardinia” published in Cagliari in 1875. Spano, who studied Oriental Languages in Rome at the University “La Sapienza” and not in an Ecclesiastical or Pontifical institution, was a pioneer in the study of the presence of the Jews in Sardinia. He considered the Jews as Sardinian people for almost 1500 years and appreciated their values and merits in the development of the commercial activities. His attitude towards them is characterized by a total absence of anti-Semitism, which on the contrary was still widespread in the Catholic Church at that time, and by a sympathetic evaluation of their capacities. In the second part the author describes two Hebrew manuscripts which belonged to Giovanni Spano’s collection, now preserved at the University Library in Cagliari. These manuscripts escaped from the census carried out from the Sixties of the 20th century by the Institute of Microfilmed Hebrew Manuscripts in Jerusalem. The manuscript 197, copied in Emilia Romagna - northern Italy during the 15th century and belonged to some members of the Finzi Jewish family of Reggio Emilia, contains prayers for the Jewish Holydays celebrations of the liturgical year. The second manuscript, bearing the call number 194, was copied in the Tunisian area during the 17th century and is a miscellany of Magical texts and recipes and of astrology as well. In the third part the author describes some documents relating to the Jewish presence in Sardinia. In particular the upper part of two funerary Jewish lamps decorated with a menorah, discovered recently in Porto Torres, and a fragment of white marble with incised a five-branch menorah: all these findings date back to the 4th-5th century C.E. Finally a vellum handwritten folio in Latin and Hebrew, discovered in the Eighties of past century reused as binding in the Diocesan Archive Lanusei, is described. The content of the two pages, which has never been identified, is a part of the Pugio fidei, a work composed in the second half of the 13th century by the Catalan Dominican friar Ramón Martí. In this work for the first time he tries to prove the truth of the Christian religion in order to convert the Jews starting from the Hebrew and Aramaic texts of rabbinic literature, which thanks to the Pugio became known to the Christian world for the first time
Deleverage, balance sheet restructuring and economic policy in Italy
No full textThis study documents and comments on financial assets dynamics in Italy before and after the 2007–08 crisis, based on an empirical observation of twenty-five years of fully integrated sectorial data reporting economic transactions, financial transactions, and revaluation of assets.
The empirical analysis strongly suggests that Italy experienced a peculiar form of balance sheet restructuring, different from both the typical balance sheet recession—where private debt deleverage starts as stock prices fall—and the typical low demand recession— where private debt deleverage starts as GDP recovers. In Italy, debt deleverage of both firms and households did not start until 2012, when equity values recovered and GDP fell; moreover, deleverage was not spontaneous, but was triggered by an articulated process of financial wealth reallocation driven by the European Central Bank. Fiscal policy, rather than creating the conditions for economic growth by reducing public debt, created the conditions for private debt reimbursement by compressing aggregate demand. Monetary policy, rather than expansionary, has been functional in recovering and preserving the value of equities while progressively shrinking the debt security market. This combined policy also restored the pre-crisis context of low-income growth, low public expenditure, and structurally high unemployment
Il problema del debito privato e lo scopo del debito pubblico
No full textL’emergenza pandemica, vista dalla prospettiva delle sue conseguenze economiche, ha portato in primo piano un problema sistemico che spesso, per ideologia o per ignoranza, nel dibattito pubblico viene lasciato sotto traccia: la questione del debito privato
In seguito al prevedibile crollo del Pil di diverse economie, in primis quella italiana, il debito privato, in particolare quello delle imprese, rischia di diventare insostenibile

A M-PSK Timing Recovery Loop Based on Q-Learning
No full textIn this work we propose a digital symbol synchronizer for M-PSK modulations based on the Q-Learning algorithm. Through Reinforcement Learning, the system is able to autonomously adapt to environment changes, learning the correct Timing Recovery Loop behavior. The proposed synchronizer has been tested considering a white gaussian noisy channel. We analyzed the modulation error rate and the signal to noise ratio. The obtained results show improved timing recovery capabilities exhibiting a lower locking time
