    Preemption-aware planning on Big-Data systems

    No full text
    Recent developments in Big Data frameworks are moving towards reservation based approaches as a mean to manage the increasingly complex mix of computations, whereas preemption techniques are employed to meet strict jobs deadlines. Within this work we propose and evaluate a new planning algorithm in the context of reservation based scheduling. Our approach is able to achieve high cluster utilization while minimizing the need for preemption that causes system overheads and planning mispredictions

    A Florentine family in crisis: the Strozzi in the fifteenth century.

    No full text
    PhDIn 1434 the Strozzi lineage had held a leading position in Florentine society and government for at least one hundred and fifty years, and was one of the largest and wealthiest of the city's patrician lineages. The records of the catasto of 1427 and of the scrutiny of 1433 are used to give a profile of the dominant social, economic and political position of the Strozzi before the advent of Medicean dominance. Their record of electoral success, and the political and cultural leadership of influential and respected men such as Palla di Nofri and Matteo di Simone, with other factors, put the Strozzi amongst the greatest enemies of the victorious Medicean regime of late 1434. The effects of political opposition and exile on the lineage are examined both directly, through records of office-holding, and indirectly through such indicators as marriage alliances and household wealth. The two most prominent lines of the Strozzi were exiled after 1434. Palla di Nofri's life and preoccupations in his Paduan exile are examined, together with the lives of his sons; none of these Strozzi ever returned to Florence, pursued as they were by the enmity of the Medicean regime. The very different careers of Filippo di Matteo and his brother Lorenzo are also examined: how they succeeded in founding a lucrative bank in Naples, and in returning to Florence to 'rebuild' (rifare) the position of the Strozzi lineage there. The final decades of the century saw the Strozzi in an economically more secure position, due substantially to the efforts of Filippo. Except for a very small number of its members admitted into the regime, most of the lineage is here shown to have remained excluded from significant political office until after the fall of the Medici regime in 1494

    Objectives. Graves' disease (GD) is the most common cause of hyperthyroidism, and accounts worldwide for 60-80% of all cases. The diagnosis is based on clinical findings, and is confirmed by the presence of TRAB, suppression of TSH, and elevation of free thyroxin (free T4), and triiodinethyronin (free T3). GD can be treated by antithyroid drugs, radioactive iodine, or surgery. The aim of this study was to review retrospectively the surgical management, in terms of safety and efficacy, in 50 patients operated in the Department of Surgical Sciences since 2005 through 2010 and followed up at the Endocrinology Unit A of the Experimental Medicine Department. We assessed postoperative complications, which included the presence, persistence and development of ophthalmopathy, transient hypocalcemia, permanent hypoparathyroidism and recurrent laryngeal nerve palsy. Materials and Methods. We analyzed data from 50 patients with GD who were eligible and underwent Total Thyroidectomy (TT). Thirty-nine patients underwent TT for recurrent hyperthyroidism after medical therapy and eleven patients for severe ophtalmopathy. The mean follow up was 41 months (range: 10-70). Results. Eleven patients had ophtalmopathy before surgery. Four patients developed an ophtalmopathy after surgery. Eleven patients presented hypocalcemia, transient in ten patients and permanent in one patient. Five patients developed a transient disphony. Conclusions. Total thyroidectomy is a safe and radical procedure in Graves' disease treatment. Complications of TT are not different than subtotal thyroidectomy if it's performed by expert surgeons

    MORPHOLOGY AND EVOLUTION OF COASTLINES AND SEABEDS The session "Morphology and evolution of coastlines and seabeds" has faced a theme that is becoming increasingly important because coastal areas are characterized by high-anthropic pressure, relevant socioeconomic interests besides being very sensitives to the effect of climate changes. The title of the session aims to underline how the coastal areas are a multifaceted system constituted by both emerged and submerged areas that are in continuous and mutual evolution. Although the symposium starting date had unfortunately fallen during the Covid-19 emergence, several international and national researchers have brought their contributions to the session. The issues addressed, mainly concern a series of case-histories (Italy, Spain, Turkey and Croatia) illustrating coastline changes along the time and, in some instances, their relationships with beach nourishment or coastal defenses. Studies about the influence of fluvial sedimentary supply on the offshore area and the effects of intensity water circulation in strongly anthropized areas are also presented. The acquisition of data of the scientific contributions derives from different approaches: i) analysis of aerial and satellite images, ii) laboratory analyses of samples collected in the study area, iii) experimental tests. Gomes da Silva et al. show how the use of automatic co-registered Landsat and Sentinel-2 satellite images allows them to obtain accurate shoreline series in the Tordera Delta area (Spain). A complementary approach is proposed by Pagán et al. that analyses aerial images spanning from 1956 to 2019 and reconstruct the coastal evolution along the Alicante coast (Spain) testing the impact of beach nourishment that occurred since the 1990s. Similar is the methodological approach proposed by Kadri and Atroune to evaluate the diachronic evolution of the Bordj El Kiffane coastline (Algeria) with respect to the presence or absence of protection structures. Piccioli-Resta et al. have utilized a remotely piloted aircraft systems (RPSA) along the Lecce coast (Italy), for the monitoring of the beach dunes and the nearby shorelines. A similar technique was also utilized by Bedini et al., to monitoring the Poseidonia oceanica meadows evolution in the Follonica and Baratti gulfs (Italy). The drone-survey has evidenced the unsuitability of the coastal defenses used up now. A direct sedimentological approach is proposed by López et al. to investigate, within three beaches located in Spain, the relationship between sediment wear and shoreline evolution through the use of the accelerated particle wear test (APW). Pikelj and Furčić analyze several seabed samples collected in front of a coastal cliff subjected to erosional processes at the Vrgada Island, in Croatia.

Di Leo et al. present a sedimentological and geochemical-based study to establish the influence of the Sarno river on the present-day sedimentation in the Naples (Italy) bay evaluating grain size, the presence of organic matter, and the pollution degree of the sediments samples collected in the offshore area of the bay. Bulkan et al. use a stratigraphic perspective to infer the depositional coastal evolution of the Lake Bafa area (Aegean coast, Turkey), which occurred during the last 3,5 ka. Through the study of six cores, they document the succession of four phases, from the earlier marine-dominated stage to the present-day isolated lacustrine stage. Finally, Di Natale et al. by means of the implementation of experimental tests of a three-dimensional physical model, carry out an evaluation of the intensity water circulation within marinas and defense structures located in relevant sites of Italy (Salerno and Ischitella stretch of coast along with the harbors of Fiumicino Manfredonia and Castelvolturno).

    Commentaries and cases on italian business law

    No full text
    This casebook deals with the basic principles of the Italian business law and focuses on certain recent and pivotal cases in which important rules governing the modern public company have been applied. After a short overview of the main corporate and securities laws and regulation applicable to Italian listed companies, certain leading cases which triggered the application of such rules are analyzed. The main interrelationships between and among the economic and legal elements are scrutinized for the purpose of highlighting the economic logic underlying corporate law. In the financial markets’ dynamics, the public company plays a vital role since it attracts the public savings coming from the investors in order to finance business plans and strategies which create growth and welfare. In such a scenario, financial intermediaries must act in the interest of the investors, selecting among the potential issuers those who are the most attractive for their clients. When companies are structurally organized to attract standardized equity or debt investments, by issuing listed shares, bonds or other financial instruments, their operational and governance rules change in order to safeguard the public savings coming from the investors. In the end, what makes this branch of law so interesting to students, practitioners, and scholars alike is the open-textured relationship between corporate law and securities regulation which plays a crucial role in such context. The cases selected in the second part of this book deal with significant topics in the Italian market practice and are briefly commented making reference to an updated set of laws and references. Therefore, this book can be used also with a focus on comparative legal systems for corporations taught in Italy or abroad

    The “accountant” stereotype in the Florentine medieval popular culture: “galantuomini” or usurers?

    No full text
    Purpose – This paper explores the stereotype of the accountant in Florentine medieval popular culture based on literary works and from a historical perspective. It aims to highlight how stereotypes change with time and represent the cultural and historical evolution of a society. This research challenges Miley and Read (2012), who stated that the foundation of the stereotype was in Commedia dell’arte, an Italian form of improvisational theatre commenced in the 15th century. Design/methodology/approach – The authors applied a qualitative research method to examine the accountant from a medieval popular culture perspective. The analysis consists of two phases: (1) categorisation of the accountant stereotype based on accounting history literature and (2) thematic analysis of The Divine Comedy (1307–1313) and The Decameron (1348–1351). The authors explored a synchronic perspective of historical investigation through a “cross-author” comparison, identifying Dante Alighieri as the first key author of medieval popular culture. During his imaginary journey through The Divine Comedy, Dante describes the social, political and economic context of the Florentine people of the 14th century. Then, with its various folkloristic elements, The Decameron of Giovanni Boccaccio becomes the “manifesto” of the popular culture in the Florentine medieval times. Findings – This study shows the change of the accountant stereotype from the medieval age to the Renaissance. The Divine Comedy mainly connotes a negative accountant stereotype. The 14th century’s Florentine gentlemen (“i galantuomini”) are apparently positive characters, with an ordered and clean aspect, but they are accused of being usurers. Dante Alighieri pictures the accountant as a “servant of capitalism”, “dishonest person, excessively fixated with money”, “villain and evil” and “excessively rational”. Giovanni Boccaccio mainly portrays a positive accountant stereotype. The accountant is increasingly more reliable, and this “commercial man” takes a more prestigious role in the society. In The Decameron, the accountant is depicted as a “hero”, “gentleman”, familyoriented person with a high level of work commitment” and “colourful persona, warm, and emotional”. Overall, the authors provided new evidence on the existence of the accountant stereotype in the Florentine medieval popular. Originality/value – This study engages with accounting history literature accountants’ stereotypes in an unexplored context and time period, providing a base for comparative international research on accounting stereotypes and popular culture. Additionally, it addresses the need for further research on the accountant stereotype based on literary works and from a historical perspective. Therefore, this research also expands the New Accounting History (NAH) literature, focussing on the investigation of the accountant stereotype connotations in the 14th century

    Use of nebulized liposomal amphotericin B and posaconazole as antifungal prophylaxis in patients with severe SARS-CoV2 infection in intensive care unit

    Purpose COVID-19 associated pulmonary aspergillosis (CAPA) is common and linked with high fatality rates. To assess the impact on the incidence and outcome of CAPA of an antifungal prophylaxis (AFP) we compared two cohorts of COVID-19 patients admitted to intensive care units (ICU) in Brescia, Italy, from January to August 2021. Methods The study cohort included all mechanically ventilated patients observed between April 2021 and August 2021 with SARS-CoV-2-pneumonia, who received AFP with oral posaconazole (200 mg every 6 h) and nebulized liposomal amphotericin B (50 mg every 2 weeks) from ICU admission to 7 days after discharge or, if applicable, until tracheostomy removal. The control cohort included COVID-19 patients admitted to the same ICU between January and March 2021 who did not receive any AFP. Subjects with CAPA at ICU admission were excluded. Results We included 270 patients, of whom 64 (23.7%) received AFP. In patients in the study group, CAPA-related mortality was significantly reduced (29% vs. 48% p = 0.04), as well as the incidence of CAPA (3.1% vs 12.1%, p = 0.03). Patients who developed CAPA were older (mean of 70-y-old vs 63-y-old, p < 0.001). One subject discontinued posaconazole due to an adverse reaction. Among the 46 patients who received it, only one patient reached an effective plasma concentration of posaconazole. Conclusion AFP was associated with reduced incidence and mortality from CAPA and was well tolerated in patients with severe COVID-19. Posaconazole concentrations below the efficacy threshold in almost all patients may be attributable to drug interactions and prompt further studies to define its clinical significance

    Il Vangelo secondo Matteo di Pier Paolo Pasolini (1964). Una religiosità profonda e tormentata.

    No full text
    ItPressoché unanimemente considerato dalla critica, anche cattolica, il miglior film su Gesù mai girato, il Vangelo secondo Matteo di Pier Paolo Pasolini ci rivela anche i tormenti dell'anima del regista che, comunista seppure eretico ed espulso dal partito, e ateo e anticlericale dichiarato, avvertiva profondamente l'esigenza del sacro e trovava un punto di conforto e di sostegno nella sua ricerca nella figura di papa Giovanni XXIII il cui avvento sul soglio di Pietro e la convocazione successiva del Concilio Vaticano II contrassegnarono il periodo storico e politico-religioso in maniera indelebile. Pasolini, pur da non credente, si accostò con estremo rispetto al testo matteano e realizzò un film fedele al racconto evangelico, ma non alla sua ispirazione, perché la figura di Cristo ne esce ridotta alla dimensione di un eroe mitico del quale Pasolini illustra discorsi e azioni, ma non intende le loro motivazioni profonde.EnAlmost unanimously considered by critics, also Catholic, the best movie about Jesus ever made, the Vangelo secondo Matteo by Pier Paolo Pasolini also reveals the torments of the soul of the filmmaker who, although communist and atheist and anti-clerical declared, deeply felt the need of the sacred. An element of comfort and support in his research was the figure of Pope John XXIII whose advent on the throne of St. Peter and the subsequent convocation of the Second Vatican Council undoubtedly marked the historical and political-religious period and, according to the same author, was the inspiration of his choice. Pasolini, though not a believer, approached with the utmost respect to the Matthean text and made a movie faithful to the story of the Gospel, but not to his inspiration, be-cause the figure of Christ takes on the dimension of a mythical Hero whom Pasolini shows speeches and actions, but he doesn't understand the deep motivations of them
