- During the last ten years the number of immigrants has rapidly risen in Italy, reaching almost the 6% of the total population. Immigrants come from more than 190 different countries and their health is a crucial capital to enter the labour market, where they play an important role, even if the achievement of social integration is still a challenge. As the monitoring of immigrants health status is an important mean to plan the actions to tackle health inequalities and to improve their health conditions, it is necessary that the National Health System develops a common methodology and produces some shared indicators to perform it. To achieve this aim a national board on the project Promoting immigrants health in Italy has been established and it is now working to find the sources of data and a reduced number of useful health indicators, measurable all around the Country. This paper presents a summary of the main informations provided by the board up to now. Keywords: immigrants, health, socio-economic status, pregnancy, indicators, epidemiology. Parole chiave: immigrati, salute, condizione socio-economica, gravidanza, indicatori, epidemiologia.

Full textAbstract:
Routines and meaningful rituals play an important role in the family dynamic system. During the past 30 years, migratory flow into Italy has been constantly increasing. Our aim was to explore the structure of daily life in order to understand and compare family functioning of migrant couples in Italy with the family functioning of couples who were born and bred in Italy. In our study there were 124 participants (31 Italian couples and 31 migrant couples) who completed modified versions of the Family Routine Inventory and the Family Ritual Questionnaire. Participants were contacted by teachers at kindergartens attended by the children of the couples. The results highlighted a significant difference between Italian and migrant couples in the symbolic-significance dimension of rituals. The particularity of this finding is its coexistence with the absence of significant differences in the more pragmatic aspects of rituals. The possible influence of the migration experience and practical implications are discussed.

Full textAbstract:
Differences in jurisdictional public health actions have played a significant role in the relative success of local communities in combating and containing the COVID-19 pandemic. We forecast the possible COVID-19 outbreak in one US state (Utah) by applying empirical data from South Korea and Italy, two countries that implemented disparate public health actions. Forecasts were created by aligning the start of the pandemic in Utah with that in South Korea and Italy, getting a short-run forecast based on actual daily rates of spread, and long-run forecast by employing a log-logistic model with four parameters. Applying the South Korea model, the epidemic peak in Utah is 169 cases/day, with epidemic resolution by the end of May. Applying the Italy model, new cases are forecast to exceed 200/day by mid-April, with the potential for 250 new cases a day at the epidemic peak, with the epidemic continuing through the end of August. We identify a 3-month variation in the likely length of the pandemic, a 1.5-fold difference in the number of daily infections at outbreak peak, and a 3-fold difference in the expected cumulative cases when applying the experience of two developed countries in handling this virus to the Utah context.

Full textAbstract:
From the late 1940s on, the United States did its best to prevent the Italian Communist Party (PCI)from gaining a role in the Italian government. When Jimmy Carter took office in Washington in 1977, the PCI once again was maneuvering for a share of power in Rome. Some observers in Italy speculated that the new U.S. administration would be less averse than its predecessors had been to the prospect of Communist participation in the Italian government. The Carter administration's initial statements and actions created further ambiguity and may have emboldened some senior PCI officials to step up their efforts to gain at least a share of power. Faced with the prospect that Communists would be invited into a coalition government in Italy, the Carter administration dropped its earlier caution and spoke out unequivocally against a “historic compromise” involving the PCI. Although it is difficult to say whether the more forceful U.S. stance made a decisive difference, the ruling Christian Democrats in Italy were able to keep the Communist Party out of the government.

Full textAbstract:
The aim of this paper is to examine the earnings dynamic in Italy, in order to explain earnings differences between southern Italy and centralnorthern Italy. In our analysis we use different techniques: ordinary least squares (OLS), quantile regression models and the algorithm developed by Machado and Mata (2005). In particular, the Machado and Mata (2005) algorithm allows us to examine the relative importance of both differences in workers? characteristics and in their returns in explaining southern, central and northern Italy earnings differences at a point in time, as well as across time within each macro-area. We focus on the role of differences in educational endowment and returns to education, one of the most important components of human capital in the stylised literature. The level of education determines the substantial disparities in terms of wage returns. However, this holds only for levels of education related to compulsory education.

Full textAbstract:
AbstractUsing a rich micro dataset drawn from administrative archives, we explore whether Social Security Wealth (SSW) is an important factor affecting the decision to become self-employed. We focus on the two main categories of self-employed professions covered by the Italian public pension system: craftsmen and shopkeepers. We use the large exogenous variation in individual expected SSW that occurred as a result of the policy reform process undertaken in Italy during the 1990s to identify the effect of this variable and we study how the probability of being self-employed or employed depends, amongst other things, on the difference in the expected SSW that accrues under the two alternative employment scenarios. Our key finding is that a higher difference in expected SSW from self-employment compared with employment has a positive effect on the probability of being self-employed and on the probability of switching to self-employment, whereas it has a negative effect on the probability of switching from self-employment to employment.

AbstractCase-Fatality Rate (CFR) for COVID-19 in Italy is apparently much higher than in other countries. Using data from Italy and other countries we evaluated the role of different determinants of this phenomenon. We found that the Italian testing strategy could explain an important part of the observed difference in CFR. In particular, the majority of patients that are currently tested in Italy have severe clinical symptoms that usually require hospitalization and this translates to a large CFR. We are confident that, once modifications in the testing strategy leading to higher population coverage are consistently adopted in Italy, CFR will realign with the values reported worldwide.

Full textAbstract:
The absorption of the Greek world into the Roman empire created intellectual problems on several levels. In the first instance, Greek confidence in the superiority of Hellenic culture made explanations for the swiftness of Roman conquest all the more necessary. In accounting for Rome's success, Greeks focused on the structure and character of the Roman state, on Roman attitudes towards citizenship, and on the nature of the Roman constitution. Greeks initially attempted to understand Roman institutions and beliefs by assimilating them to paradigms within Hellenistic political thought. On the one hand, this process tended to obscure substantial differences between Greek and Roman political theory. At the same time, appreciation of Rome's relations with Italy created a means through which Greeks could imagine their own integration into the Roman community. Among the conceptual models available to Greeks of this age, only the polis provided a paradigm for a collectivity in which individuals had equal rights and toward which they directed their patriotic sentiments. That Roman Italy was not a polis did not force the coinage of new terminology: the polis formed a conceptual boundary that Hellenistic political philosophy never truly escaped. Repeated construals of Roman ideas and institutions on analogy with polis-based models ultimately forced a shift in the semantic fields of Greek political terminology and altered Greeks' conceptual archetype of the political collectivity. This process provided a framework within which Greeks could justify their wholesale participation in imperial culture and political life: they could, on these terms, argue that the gradual evolution of the world toward a single, unified empire actualized man's natural tendency to center his life around a single polis.

(1) Background: Although the current literature shows that daylight saving time (DST) may play a role in human health and behavior, this topic has been poorly investigated with reference to Obstetrics. The aim of this case–control study was to evaluate whether DST may influence the number of spontaneous deliveries. (2) Methods: A low-risk pregnancy cohort with spontaneous onset of labor (n = 7415) was analyzed from a single Italian region for the period 2016–2018. Primary outcome was the number of spontaneous deliveries. Secondary outcomes were: gestational age at delivery, type and time of delivery, use of analgesia, birth weight, and 5-min Apgar at delivery. We compared the outcomes in the two weeks after DST (cases) to the two weeks before DST (controls). (3) Results: Data showed no significant difference between the number of deliveries occurring before and after DST (Chi-square = 0.546, p = 0.46). Vaginal deliveries at any gestational age showed no statistical difference between the two groups (Chi-square = 0.120, p = 0.73). There were no significant differences in the secondary outcomes, as well. (4) Conclusions: DST has neither a significant impact on the number of deliveries nor on the obstetric variables investigated by this study.

Resumen: A menudo, el interés científico por la sal ha encontrado provechosos socios en los investigadores de la economía romana, más que en su relación simbólica con los pobladores. Por ello, el estudio se propone analizar la relación existente entre la sal y la religión romana, tomando para ello el ejemplo del culto de Hércules en Roma, Ostia y el centro de Italia. Con ese fin se analizará en un primer momento la figura del dios itálico en su contexto originario, subrayando sus diferencias conceptuales con el dios grecorromano más tardío y su relación con la sal y su culto urbano. En un segundo momento, se revisará el papel que desempeña el dios con la ciudad de Ostia y su casuística, para, en último lugar, estudiar la devoción de la divinidad en el centro de Italia, tremendamente radicada desde tiempos muy remotos en santuarios como el de Alba Fucens.Abstract: The scientific interest in salt has often found useful partners in researchers of the Roman economy, rather than in its symbolic relationship with the settlers. For this reason, the study aims to analyse the relationship between salt and Roman religion, taking the example of the cult of Hercules in Rome, Ostia and central Italy. To this end, the figure of the Italic god in its original context will be analysed first, highlighting its conceptual differences with the later Greco-Roman god and its relationship with salt and its urban cult. In a second moment, the role that the god plays with the city of Ostia and its casuistry will be reviewed, in order to, finally, study the devotion of the divinity in the centre of Italy, tremendously rooted since very remote times in sanctuaries such as that of Alba Fucens.Palabras clave: Sal, religión romana, Hércules, Roma, Ostia, Alba Fucens, Via Salaria.Key words: Salt, Roman Religion, Hercules, Rome, Ostia, Alba Fucens, Via Salaria.

Full textAbstract:
Bruno Trentin. Lavoro, libertà, conoscenza takes into consideration the figure of Bruno Trentin (1926-2007) and his work as a union leader and politician, his numerous writings in the framework of the history of Republican Italy and the transformations induced by the processes of globalisation. From this reflection, conducted from different disciplinary angles and with different political and cultural sensitivity, what emerges clearly is the extremely idiosyncratic significance of Bruno Trentin in both the practice and the theoretical analysis of the labour struggle and the exploration of its problems. A historic contribution featuring a wealth of suggestions, intuitions and reflections, capable of interpreting events and their potential union and political repercussions, within a project for the enhancement of liberty and the social and cultural role of work conducted in an extraordinarily innovative and far-sighted manner.

Full textAbstract:
More than fifteen years after the introduction of direct election, the mayors are still the most popular politicians in Italy. The personal relationship set up with the citizens and the strengthening of the city councils has restored energy and stability to the action of the municipal administrations. Nevertheless, these institutional reforms, while important, have failed to guarantee good government. The effects of the mayoral reform are, in fact, considerably different from one city to another, and from one type of policy to another. What does this variety of results derive from? The book provides an answer to this question through an investigation of the decisional processes of around a hundred "local collective assets" in six large metropolitan cities. To explain the different outcomes – in addition to the "council effect", that is, the relevance of policy, and the "sector effect", the relevance of the different decisional milieus – the authors also underscore the role of the "governance effect", namely the different approaches to decision-making and building consensus on urban policies.

Full textAbstract:
This book focuses on the referendums against water privatization in Italy and explores how activists took to social media, ultimately convincing twenty-seven million citizens to vote. Investigating the relationship between social movements and internet-related activism during complex campaigns, this book examines how a technological evolution — the increased relevance of social media platforms — affected in very different ways organizations with divergent characteristics, promoting at the same time decentralized communication practices, and new ways of coordinating dispersed communities of people. Matteo Cernison combines and adapts a wide set of methods, from social network analysis to digital ethnography, in order to explore in detail how digital activism and face-to-face initiatives interact and overlap. He argues that the geographical scale of actions, the role played by external media professionals, and the activists’ perceptions of digital technologies are key elements that contribute in a significant way to shape the very different communication practices often described as online activism.

Full textAbstract:
Focusing on the history of scientific and technological development over recent centuries, the book is dedicated to the history of telecommunications, where Italy has always been in the vanguard, and is presented by many of the protagonists of the last half century. The book is divided into five sections. The first, dealing with the origins, starts from the scientific bases of the evolution of telecommunications in the nineteenth century (Bucci), addressing the developments of scientific thought that led to the revolution of the theory of fields (Morando), analysing the birth of the three fundamental forms of communication – telegraph (Maggi), telephone (Del Re) and radio (Falciasecca) – and ending with the contribution made by the Italian Navy to the development of telecommunications (Carulli, Pelosi, Selleri, Tiberio). The second section, on technical and scientific developments, presents the numerical processing of signals (Rocca), illustrating the genesis and metamorphosis of transmission (Pupolin, Benedetto, Mengali, Someda, Vannucchi), network packets (Marsan, Guadagni, Lenzini), photonics in telecommunications (Prati) and addresses the issue of research within the institutions (Fedi-Morello), dwelling in particular on the CSELT (Mossotto). The next section deals with the sectors of application, offering an overview of radio, television and the birth of digital cinema (Vannucchi, Visintin), military communications (Maestrini, Costamagna), the development of radar (Galati) and spatial telecommunications (Tartara, Marconicchio). Section four, on the organisation of the services and the role of industry, outlines the rise and fall of the telecommunications industries in Italy (Randi), dealing with the telecommunications infrastructures (Caroppo, Gamerro), the role of the providers in national communications (Gerarduzzi), the networks and the mobile and wireless services (Falciasecca, Ongaro) and finally taking a look towards the future from the perspective of the last fifty years (Vannucchi). The last section, dealing with training and dissemination, offers an array of food for thought: university training in telecommunications, with focus on the evolution of legislation and on the professional profiles (Roveri), social and cultural aspects (Longo and Crespellani) as well as a glance over the most important museums, collections and documentary sources for telecommunications in Italy (Lucci, Savini, Temporelli, Valotti). The book is designed to offer a compendium comprising different analytical approaches, and aims to foster an interest in technology in the new generations, in the hope of stimulating potentially innovative research.

Full textAbstract:
The Faculty of Political Science of Florence – the oldest school of political and social science in Italy, founded in 1875 by Carlo Alfieri and named after his father Cesare – has a tradition of study that is widely recognised, even abroad, to which the cultural project of this series is related. The first book is dedicated to the research activity carried out by Luciano Cavalli and the profound traces that it has left on Italian and European sociology. Now Professor Emeritus, Luciano Cavalli taught and worked at the "Cesare Alfieri" for many years from 1966 on. Around his commitment as a "pioneer" of sociology in Italy he mustered an array of sociologists, active in different universities, many of whom have opened up new frontiers within the discipline and have successfully cultivated a dialogue with the other social sciences, as the contents of the book clearly illustrate. This extensive collection of essays offers a clear image of the fertile sociological work that burgeoned around the scientific commitment of Luciano Cavalli and was often generated by his own action of cultural stimulus. The three sections into which the book is divided – Portrait of an intellectual, The sociology of political phenomena and Sociological theory and social change – address issues of great relevance to the contemporary sociological debate. The rapport between the democratic construction of the modern State and the role and functions of the leadership, the relations between citizens and leaders, the various forms of the democratic institutional structures and the transformations of political culture are interwoven with the Neo-Weberian interpretation of the charisma theory that Cavalli masterfully proposed. Also particularly significant and topical are the critical reflections made by writers whose scientific itinerary has run parallel to that of Cavalli for decisive stretches, and who were and are bound to his teaching when they tackle arguments such as the changes in urban life, immigration and the problems of economic, political and social development in our times.

Full textAbstract:
This book is a collection of the proceedings of the study seminar held in Verona on 14 November 2003. This was the occasion for the presentation of the results of archive research performed by young researchers on the Jewish presence in numerous cities and smaller towns of the Venetian hinterland in the fifteenth century (Vicenza, Verona, Treviso, Feltre, and the minor centres of the Polesine and Verona and Vicenza territory). The various themes that are developed though attentive and documented analysis include: the autonomous initiative of the civic communities in the relation with the Jewish moneylenders and the attitude of Venice, divided between protection and the anti-Jewish tensions that were widespread among the lagoon nobility; the encounter and dialectic between the Ashkenazi and Italian components in the communities settled within the cities and hamlets of Veneto; the difference of the social and cultural climate between the first and second half of the fifteenth century, marked by incisive Franciscan preaching and attempts at expulsion from the cities; a look 'from the inside' which opens up the role of women in the economic life of the Jewish communities. Over twenty years after the convention on 'The Jews and Venice' promoted by the Fondazione Cini, these contributions illustrate the revival of study and the ever-present need for comparison and exchange on the issue of the Jewish presence in Italy.

Full textAbstract:
The middle decades of the fourteenth century saw a change in the nature of the humanists’ enthusiasm for Empire. Often closely associated with the papal court, either as civic administrators in Rome, or as benefice holders or rhetoricians in Provence, they appealed to imperial authority out of a concern for the ‘Italic world’. This depended above all on the restoration of Rome. Only when the Eternal City had been returned to its ancient glory would Italy know peace and liberty; and it was hence upon the emergence of a truly ‘Roman’ emperor that the humanists now pinned their hopes. At times, this could be one who had already been elected king of the Romans, or even crowned emperor; but, as this chapter demonstrates, the imperial mantle could also be draped about the shoulders of entirely different political actors, or even placed in the hands of the Romans themselves.

Full textAbstract:
This chapter analyses the text and epigraphy of two monumental inscriptions in Rome; both are important sources of information on landholding in early medieval Italy, and both shed light on the development of the Patrimony of St Peter and the evolving power of the popes as de facto rulers of Rome and its environs in the seventh and eighth centuries. Pope Gregory the Great (d. 604) commissioned the earlier of the two inscriptions for the basilica of St Paul, where it still survives (MEC I, XII.1). The inscription preserves the full text of a letter from Gregory to Felix, rector of the Appian patrimony (Ep. XIV.14). It ordered Felix to transfer the large estate (massa) of Aquae Salviae, with all its farms (fundi) as well as other nearby properties, from the patrimony into the direct control of the basilica of St Paul in order to fund the provision of its lighting; it was one of the last letters that Gregory wrote. The patron of the second inscription was Gregory’s eighth-century namesake and successor, Pope Gregory II (715–31), indignus servus (MEC I, XIV.1). This one is fixed in the portico of the basilica of St Peter, where it stands alongside another eighth-century inscription, namely, the epitaph of Pope Hadrian I that was commissioned by Charlemagne after Hadrian’s death in 795. Gregory II’s inscription also records a donation in Patrimonio Appiae, this time to provide oil for the lights of St Peter’s. This chapter investigates the form, content, and historical context of the production and display of these two inscriptions, analysing parallels and differences between them. It considers what they reveal about estate organization and the development of the territorial power of the papacy in this formative period, as well as the role of Gregory the Great as an exemplar for the early eighth-century popes.

Full textAbstract:
The present work represents the first full-length investigation of Italian Renaissance literature on the topic of conspiracy. This literary output consists of texts belonging to different genres that enjoyed widespread diffusion in the second half of the fifteenth century, when the development of these literary writings proves to be closely connected with the affirmation of a centralized political thought and princely ideology in Italian states. The centrality of the issue of conspiracies in the political and cultural context of the Italian Renaissance emerges clearly also in the sixteenth century in Machiavelli’s work, where the topic is closely interlaced with the problems of building political consensus and the management of power. This monograph focuses on the most significant Quattrocento texts examined as case studies (representative of different states, literary genres, and of both prominent authors—Alberti, Poliziano, Pontano—and minor but important literati) and on Machiavelli’s works where this political theme is particularly pivotal, marking a continuity, but also a turning point, with respect to the preceding authors. Through an interdisciplinary analysis across literature, history, philology and political philosophy, this study traces the evolution of literature on plots in early Renaissance Italy, pointing out the key function of the classical tradition in it, and the recurring narrative approaches, historiographical techniques, and ideological angles that characterize the literary transfiguration of the topic. This investigation also offers a reconsideration and re-definition of the complex facets of fifteenth-century political literature, which played a crucial role in the development of a new theory of statecraft.

Full textAbstract:
AbstractNature-based solutions (NBS) such as rainwater gardens and permeable paving can be deployed as an alternative to conventional urban gardens to improve cities’ resilience against increasing rainfall. This study describes the application of an agent-based model (ABM) to assess the role of private gardens toward the enhancement of water management by households. The ABM simulates the process of switching from “gray” (i.e., paved) to green gardens, taking into account the effect of “soft” (garden networks and gardening workshops) and “hard” (monetary) incentives. The ABM is supported by a water balance model to consider the effect of rainfall on soil water retention. Four different cities in Europe were analyzed: Szeged (Hungary), Alcalá de Henares (Spain), Metropolitan city of Milan (Italy), and Çankaya Municipality (Turkey). The results demonstrate that greening private gardens can generate impact on water run-off and catchment in cities in the order of 5–10%, reaching picks up to 20% in certain cases. While the proposed model is not devoid of limitations, the results provide useful insights in the ways different instruments (e.g., municipal subsidies and knowledge support) could assist with the greening of private gardens for NBS promotion to respond to cities’ water management challenges.

In International Perspectives on Aging, 141–55. Cham: Springer International Publishing, 2021. http://dx.doi.org/10.1007/978-3-030-51406-8_11.
Full textAbstract:
AbstractOlder people’s social exclusion in mountain areas is often the result of service inaccessibility. Mountain territories are indeed partly characterised by a low availability of services and high transport constraints. In this environment, older people, with a lower capacity for mobility (such as impaired or not autonomous individuals), require a set of reversed mobilities, where the mobility of relatives, caregivers or shops ensures, at least indirectly, their access to relevant services. This chapter aims to stress how reversed mobilities may promote older people’s inclusion in mountain areas and contribute to a better understanding of exclusion from services. In particular, we will emphasise: (1) the interaction between different factors in constructing service inaccessibility as an exclusionary process in the lives of mountain dwelling older people; (2) the key role played by reversed mobilities in combatting older people’s experience of exclusion from services in mountain areas, as well as the environmental, economic and social costs and “new” inequalities that might be associated with this form of adaptation. Our analysis is underpinned by a focus on two European Alpine territories (Isère, France; Bergamo, Italy) as exploratory examples. The extension of our arguments to other socio-cultural contexts is also considered.

In Smart and Sustainable Planning for Cities and Regions, 129–40. Cham: Springer International Publishing, 2021. http://dx.doi.org/10.1007/978-3-030-57764-3_9.
Full textAbstract:
AbstractThe influence of urban density on household electricity consumption is still scarcely investigated, despite the growing attention to building energy performance and the electrification of heating systems advocated at the European level. While the positive correlation between urban sprawl developments and the increasing of marginal costs of public infrastructures, services, amenities, public, and private transports are known, there has been little research on the relationship between urban form and electricity consumption in residential building stock. The present work aims to contribute to filling the gap in the existing literature, presenting the early results of ongoing research on the role of urban form in the household electricity consumption in Italy and, consequently, the related energy costs. The building typology and, in general, the structure of urban dwellings, is crucial to forecasting the electricity requirements, taking into account single housing units and their spatial composition in multi-family homes and neighborhoods. After a brief literature review on the topic, the contribution presents empirical research on the electricity consumption at the municipal level in 140 Italian cities, analyzing the diverse consumption patterns under different conditions of urban density to verify whether there exists a significant statistical correlation between them. The analysis confirms that there is a statistically negative correlation between urban density and the log of electricity consumption, even if its incidence is very limited. Further investigation may highlight whether there exists a threshold for which this relationship would be reversed, explaining the higher electricity consumption in dense metropolitan areas.

Full textAbstract:
This chapter addresses Byron’s Italian lyric mode by focusing on Childe Harold IV’s description of the Palatine as an exemplary instance of sustained poetic attentiveness. It places this description alongside the accounts of the Palatine in Goethe’s Italienische Reise and de Staël’s Corinne, ou l’Italie. Comparing these three fundamental texts for the Romantic reinvention of Italy, the chapter draws out their very different ways of responding to Rome. In doing so, it contrasts the fictional and autobiographical works of de Staël and Goethe, which appropriate the ruins of Rome for their own needs and purposes, and Childe Harold IV,which offers an attentive responsiveness to Roman ruins per se. Whereas Goethe seeks an education in Rome, and de Staël finds consolation, Byron, in his poetic exploration of the Palatine, crafts an entirely original lyric mode and persona that are expressive of a heightened attention to the suggestions of Rome. The ‘eternal city’ thus becomes an ‘exhaustless mine’ (CHP, IV, 108, 128) of experiences that hosts of later tourists would then come to explore, relish and revel in.

Full textAbstract:
The chapter describes the incidence and features of poverty in the ten largest Italian cities. Exploiting the bulk of existing research, the chapter discusses how poverty is produced in each city, stressing the connection between the social organization of the urban life – including the economy, the social dynamics, the social fabric, the local politics – and the triggering of individual and household trajectories of impoverishment. Following an analysis based on maps that show how the disadvantaged population is more or less concentrated is some areas of each city, the situation of the three largest ones – Milan, Naples and Rome – is described in more detail. These three cities are very different from each other: Milan is the wealthiest city of the country, and here poverty transforms typically in social exclusion, while Naples is the ideal-typical case of Mediterranean city with a large diffusion of “integrated poverty”, but also of disqualified poverty and urban segregation. Rome is an immense territory with large dispersed and often isolated peripheries (the so-called borgate) where a highly vulnerable and variegated population live often in conflict with each other.

Full textAbstract:
This chapter examines how protagonists of the Italian revolutions of 1848, including Giuseppe Montanelli and Carlo Cattaneo, engaged with American political institutions by looking at the cases of Lombardy, Tuscany, and Sicily. Before discussing the role played by the United States of America in Italian political thought of 1848, the chapter considers Italian experience of the revolutions of 1820–1821 and 1830–1831, both of which marked a watershed for the peninsula's national movement. It shows that Italian revolutionaries addressed the United States with very different emphasis, illustrating how references to the United States could serve very different ideological purposes. With respect to Tuscany's long history of engagement with the United States, there were far fewer references to American political institutions than for instance in Sicily, where the revolutionaries adopted a monarchical constitution. The chapter also analyzes Cattaneo's involvement in the Revolution in Lombardy and his understanding of American democracy.

Full textAbstract:
The introduction of iron after 1000 BC brought new tools and weapons to Europe. Smelting technology and higher furnace temperatures were likely the key to iron production, which is generally thought to have originated in Anatolia around 1400 BC among the Hittites, but there are a few earlier examples of iron artifacts as old as 2300 BC in Turkey. Iron produced sharper, more readily available implements and was in great demand. In contrast to copper and tin, whose sources were limited, iron was found in a variety of forms in many places across the continent. Veins of iron ore were exploited in Iberia, Britain, the Alps, the Carpathian Mountains, and elsewhere. Bog iron was exploited in northern Europe. Carbonate sources of iron in other areas enabled local groups to obtain the raw materials necessary for producing this important material. At the same time, the collapse of the dominant Bronze Age civilizations of the Aegean changed the flow of raw materials and finished products across Europe. Greece fell into a Dark Age following the demise of the Mycenaean city-states. The Etruscans were on the rise in Italy. Rome was a small town at the border of the Etruscan region. Soon, however, new centers of power in classic Greece and Rome emerged, bringing writing and, with it, history to Europe. Again, we can observe important and dramatic differences between the “classic” areas of the Mediterranean and the northern parts of “barbarian” Europe. The chronology for the Iron Age in much of Europe is portrayed in Figure 6.2. The Iron Age begins earlier in the Mediterranean area, ca. 900 BC, where the Classical civilizations of Greece, the Etruscans, and eventually Rome emerge in the first millennium BC. Rome and its empire expanded rapidly, conquering much of western Europe in a few decades before the beginning of the Common Era and Britain around ad 43, effectively ending the prehistoric Iron Age in these parts of the continent. The Iron Age begins somewhat later in Scandinavia, around 500 BC.

Full textAbstract:
This chapter centres on the problematic theme of Byron’s relation to the visual arts and Italian art in particular. It offers possible keys for reading Byron’s response to the art of Italy by concentrating not so much on familiar Classical and Renaissance paintings and sculptures, but instead by focusing on the relationship between Byron’s Cain and the church art of Ravenna – its Byzantine mosaics. As there is no evidence that Byron actually saw any of these mosaics, the chapter takes an openly speculative approach to suggest a whole range of ways in which Ravennese visual art might have shaped Cain. In particular, as the chapter intimates, if ‘the form of Cain departs from all Byron’s previously stated aesthetic preferences’, it does not depart ‘from what he could see around him in Ravenna’s religious art’. Thus, the chapter’s speculative method raises some important and fundamental questions about Byron’s possible absorption of all sorts of Italian art works that he never mentions but certainly did see, the creative role of memory in Byron’s poetic responses to the art he encountered in Italy, and the poet’s more general fascination with different ways of seeing and knowing.

Full textAbstract:
Deaf children in Italy are provided with different types of schooling. Few public schools offer a bilingual curriculum for deaf and hearing students that involves consistent use of Italian and Italian Sign Language (LIS) within the classroom and in which LIS is taught as a subject. One of these schools, the Tommaso Silvestri Primary School, located in Rome, Italy, is discussed in this chapter. In particular, the way in which the program is organized and how it supports deaf and hearing students in cognition, learning, and social interaction will be described. Methodological aspects and the role of technology in enhancing learning processes will be also discussed. This kind of bimodal bilingual co-enrollment program is very useful for deaf students and constitutes a unique opportunity for hearing classmates, giving them the opportunity to experience innovative learning environments and to consider deafness as a status rather than as a limitation.

Full textAbstract:
The paper presents part of the results of two studies, the European “Radar” (Raising Awareness on renewable energy Developing Agro-eneRgetic chain models) Project and the “Energy and environmental plan for the consortium of the municipalities of the Esino-Frasassi mountain area”, conducted in an area in central Italy. The area is characterized by huge forestry biomass resources and by substantial amounts of agricultural residues. The work presents a technical-economic study of a cogeneration plant using a solid biomass-fuelled micro turbine as the prime mover. The energy conversion of solid biomass can be achieved with different technologies, e.g. organic Rankine cycles, micro turbines with an external combustion chamber, or Stirling engines. The choice of the conversion system depends mainly on biomass availability and on the level of user demand. Of the conversion technologies mentioned above, the micro turbine is suitable to meet the requirements of the cogeneration plant examined here, which is applied to a low thermal demand public building. The work describes a micro turbine based on a regenerative Brayton cycle endowed with an external combustion chamber. The inlet air, after being compressed, passes through a regenerator and then through an external furnace fuelled by solid biomass, where it is further heated, and finally expands through the turbine. The outlet air of the turbine, before being funnelled through the chimney, passes through the regenerator and subsequently through a dry kiln, thereby reducing the humidity of the solid biomass. The micro turbine studied produces 75 kWe and 300 kWt. The biomass is made up of olive tree prunings. After the technical analysis, an economic study stresses the critical role of incentives systems (herein provided by the Italian legislation) in making the technology appealing to investors in renewable energy solutions. The energy and economic analysis considers different combinations of three different amounts of annual operation hours, of two operating modes (with/without cogeneration) and three purchase prices of the solid biomass. The incentives mechanism considered is the Feed-In Tariff (FiT) granted by the Italian legislation for plants < 1 MWe. The economic analysis highlights some influential factors for solid biomass-fuelled systems: contract with fuel suppliers, biomass price, availability, transportation, storage, and processing, and plant location. In particular, the purchase price of solid biomass is substantially negotiated between the manager of the energy conversion plant and suppliers. The work demonstrates the crucial role of the incentives mechanisms for economic sustainability; the strong influence of biomass price on investment profitability; and the role of cogeneration in further shortening the payback period.

Abstract The REWEC3 (Resonant Wave Energy Converter) is a fixed oscillating water column (OWC) wave energy converter (WEC) incorporated in upright breakwaters. The device is composed by a chamber containing a water column in its lower part and an air pocket in its upper part. The air pocket is connected to the atmosphere via a duct hosting a self-rectifying air turbine. In addition, a REWEC3 includes a vertical U-shaped duct for connecting the water column to the open sea (for this reason it is known also as U-OWC). The working principle of the system is quite simple: by the action of the incident waves, the water inside the U-shaped duct is subject to a reciprocating motion, which induces alternately a compression and an expansion of the air pocket. The pressure difference between the air pocket and the atmosphere is used to drive an air turbine coupled to an off-the-shelf electrical generator connected to the grid. The main feature of the REWEC3 is the possibility of tuning the natural period of the water column in order to match a desired wave period through the size of the U-duct. The REWEC3 technology has been theoretically developed by Boccotti, later tested at the natural basin of the Natural Ocean Engineering Laboratory (NOEL, Italy), and finally proved at full scale with REWEC3 prototype built in the Port of Civitavecchia (Rome, Italy). The objective of this paper is to select and optimize a turbine/generator set of a U-shaped OWC installed in breakwaters located in the Mediterranean Sea, such as the Port of Civitavecchia, where the first prototype of REWEC3 has been realized, or the Port of Salerno or Marina delle Grazie of Roccella (Italy). The computations were performed using a time domain model based on the unsteady Bernoulli equation. Based on the time-domain model of the power plant, the following data is computed for the turbines: i) the ideal turbine diameter; ii) the generator feedback control law aiming to maximize the turbine power output for turbine coupled to the REWEC3 device for Mediterranean applications.

In this paper a dynamic simulation of a new model for a Travelling Wave Ultrasonic Motor for antennas’ reflectors positioning, developed by Alenia Spazio S.p.A. (Roma, Italy) within an Italian Space Agency (ASI) development Program, is described. The dynamic equations for the stator and the rotors of the ultrasonic motor are assumed into a differential system, whose equations are coupled by terrms which represent interface generalized forces. Neglecting transient conditions, the complete mathematic model of the system is solved and an iterative process is developed, in order to obtain the motor’s running curves for different operation parameters, geometric dimensions and physical features of the system. The algorithm is implemented in Matlab® environment and a Graphical User Interface is constructed for user-friendly managing. This model represents a simple and powerful aid to determine final motor design that can satisfy specifications or to predict motor’s behaviour under different working conditions, as orbital ones.

WAVE (Wave-powered Autonomous Vehicle for marine Exploration) is an Italian National Research Projects of Military interest (PNRM) concluded in October 2017. The final goal of the project was the enhancement of the endurance of a typical marine mission with Autonomous Underwater Vehicles (AUVs). To this aim, a system to provide a generic carrier AUV for both energy harvesting from the wave motion and low energy propulsion capabilities was developed. A first prototype of the WAVE module was realised and installed on a commercial AUVplatform. After a preliminary assessment of the integrated system at sea, a systematic experimental characterisation of the module capabilities was carried out in a controlled environment at the CNR-INSEAN test tank facility in Rome, Italy. During the three days experimentation, a considerable quantity of data related to different recreated sea conditions and WAVE module configurations was collected. This work details the energetic characterisation of the proposed system, presenting a comparison of the performance of the different WAVE module layouts in terms of average generated power. The main result emerged from the previous analysis is the identification of the most effective configuration of the WAVE module for the battery charging. A deeper processing of data will allow to critically tune the available dynamical model of the system. This way, it will be possible to evaluate, through simulations, the expected performance of the WAVE AUV under typical wave profiles of the Mediterranean sea.

The contribution aims at corroborating location-based mobile games as models for the integration of digital technologies in the educational field. They demonstrated to be valid alternatives to formal education in the applied research project: Play Design!, which addressed to high school students, interested in design-related matters, and intends to valorise the Italian design culture, transforming Milan into the stage of a double-sided story. Design is here highlighted both as a cultural heritage and a discipline, inducing the development of two different games sharing a common didactic aim: D.Hunt and D.Learn. The first one is a mobile treasure hunt illustrating the excellences of the creative production of the country, and the renowned protagonists and places of Italy- and Milan-based design: a cultural background to be preserved and valorised. The second one, instead, is a role-play, cooperative and competitive game which depicts the city as a hub for schools and universities, where design is considered a subject for didactic courses, a combination of theories and practices to be transmitted and implemented. Then, the two mobile, location-based serious games exploit this copious and multifaceted material for evident learning purposes, joining the examples of informal education to increasingly follow in future technology developments.

Fortified architecture is a widespread and peculiar typology in Italy as it represents an identifying element for communities and a reference point in the landscape. An imposing system of castles, dating back to the 11th century, characterises the area of Reggio Emilia, in the Emilia Romagna Region. Among these fortifications, Canossa Castle is an important and distinctive fortress. Built on the top of an isolated cliff, a particularly strategic and defensive point, it played a central role in the medieval European history. For instance, it was the scene of the well-known reconciliation between Henry IV and Pope Gregory VII, which ended the Investiture Controversy in 1077. The current state of ruins of this fortress is due to both centuries of neglect and to recent incongruent interventions. Therefore, archival research, in-situ inspections and photogrammetric techniques were carried out on the case study of Canossa Castle, in order to analyse the numerous restoration yards that have followed one another on the fortress in the last century. Firstly, the lack of coordination between the different interventions emerged. Furthermore, it has been observed that the principles of restoration have been disregarded several times, with consequent damage to the archaeological remains. Therefore, the present study aims to underline the importance of a critical and aware intervention plan for the conservation and damage prevention of cultural heritage, considering the possible support of HBIM tools.

Full textAbstract:
Several mitigation and adaptation strategies are proposed to tackle the environmental issues associated to massive urbanization and climate change. All these solutions are highly related to the utilization of urban surfaces (i.e. building envelopes, streets, public spaces, etc.). However, the existing trends demonstrate the lack of a systemic approach able to integrate multiple possible functions and avoid sub-optimal solutions. In this context, urban planning can play an essential role in managing conflicts among different surface uses and ensuring their integration. This involves making spatially explicit decisions about the types of surface use allowable, and their extent and location. The decision-making process needs to be supported by accurate and detailed knowledge about the spatial distribution of a variety of parameters that influence the surface uses in cities. This study presents a systematic framework to support planning decisions based on accurate, diverse and spatially explicit information, and discusses its application in a residential district located in Bolzano (Italy). The proposed method implies the assembly of a multivariate spatial database of significant morphological and environmental parameters acquired through environmental simulation techniques and on-site data collection. The three-dimensional visualization of this database represents a solid base to relate urban planning decisions on surface uses to their effects in terms of microclimatic conditions, thermal comfort, and on-site renewable energy production.

Full textAbstract:
In this paper the three-dimensional unsteady aerodynamics of a low aspect ratio, high pressure turbine stage is studied. Fully unsteady, three-dimensional numerical simulations are performed using the commercial code ANSYS-CFX The numerical model is critically evaluated against experimental data. Measurements were performed with a three-dimensional fast-response aerodynamic pressure probe in the closed-loop test rig operating in the Laboratorio di Fluidodinamica delle Macchine of the Politecnico di Milano (Italy). An analysis is first reported about the strategy to reduce the CPU and memory requirements while performing three-dimensional simulations of stator-rotor interaction in actual turbomachinery. What emerges as the best choice, at least for subsonic stages, is to simulate the unsteady behaviour of the rotor blade row alone by applying the stator outlet flow field as rotating inlet boundary condition. When measurements are available upstream of the rotor the best representation of the experimental results downstream of the stage is achieved. The agreement with the experiments achieved at the rotor exit makes the CFD simulation a key-tool for the comprehension and the interpretation of the physical mechanisms acting inside the rotor channel (often difficult to achieve using experiments only). Numerical investigations have been carried out by varying the incidence at the vane entrance. Different vane incidence angles lead to different size, position, and strength of secondary vortices coming out from the stator. The configuration is chosen is such a way to isolate the effects of the vortex-blade interaction. Results show that some general trends can be recognized in the vortex-blade interaction. The sense of rotation and the spanwise position of the incoming vortices play a crucial role on their interaction with the rotor vortices, thus determining both the time-mean and the time-resolved characteristics of the stage-exit secondary field.
