This dissertation presents the first full length study of Antonello da Messina's portraits. While Antonello has been justly acknowledged as the first Italian painter to consider the portrait an independent work of art, his portraits are often characterized as imitations of Netherlandish models, and they are rarely discussed outside of the context of Venetian or Netherlandish portraiture. This study reintegrates Antonello's portraits in the wider context of fifteenth century Italy and argues that his portraiture is deeply rooted in the interests of the most prominent early Renaissance theories of painting. Antonello is among the first Italian painters to claim the face as a locus for identification, and to answer the demand that painting capture both the physical and mental aspects of the sitter. The first chapter analyzes the recent literature on the portraits and demonstrates how they have been marginalized by scholarship despite being lauded as highly influential. The second chapter evaluates the portraits as a body of work from the standpoint of form and technique, and incorporating the most recent technical analyses, demonstrates how Antonello achieved certain effects to arrive at what may indeed be considered a wholly independent work of art. The third chapter relates how Antonello's innovations in portraiture corresponded with a growing desire for a new kind of painted portrait in the mid fifteenth century. It reconsiders the origin of the painted, three quarter view portrait in Italy and explains how ancient authors presented a challenge for the painted portrait that could only be met in fifteenth century Italy by an entirely new form and style, represented in the work of Antonello da Messina. The fourth chapter examines the portraits in the context of Venetian patronage, looking more closely at his only known portrait sitters, Alvise Pasqualino and Michele Vianello, and the social and personal identities of Venetian citizens and nobles. This chapter relates how the theoretical demands of humanists translated for real patrons and collectors, and clarifies Antonello's relationship to extant portraiture in Venice at during the last decades of the fifteenth century, particularly the work of Giovanni Bellini. Ultimately Antonello da Messina's portraits had far reaching influence because they addressed some of the fundamental problems and challenges of representation in the early Italian Renaissance, for the first time, in portraiture.

Maria Messina (1887-1944) is one of the writers whose work has been "rediscovered" as a result of the recent interest in women writers of the past. Until now, criticism has tended to focus on her representation of the female condition. This thesis attempts to offer a more precise and yet more broadly contextualized characterization of her work. The analysis takes into account the social and economic upheavals of the early decades of this century which affected both men and women. In fact, the crisis of the rigid division of gender roles is shown to be the real thematic source of her work.

Interest in exploring renewable energy resources has increased globally, especially with recent worldwide intentions to maintain the global climate. Looking at the oceans as a vast sustainable clean energy resource to satisfy present high humankind energy demands has been strongly recommended. Several types of renewable energy resources exist in the oceans: waves, tides, thermal and salinity variations, currents, and offshore winds. Exploiting tidal currents is considered one of the most effective approaches to the generation of electricity. Tidal turbines are deployed beneath the sea surface to transfer the kinetic energy in tidal currents to mechanical energy suitable for ongoing conversion to electricity and subsequent transmission. However, choosing a suitable site to deploy these turbines is not a trivial process. Various constraints must be satisfied subject to basic criteria dependent upon local factors, technology limitation and economic consideration. In addition, an important issue to consider is taking care to harness energy from tidal currents with minimum possible impact on the surrounding environment. The present study justifies the nomination of the Strait of Messina as an exceptional tidal current energy resource within the Mediterranean Sea basin. The maximum tidal current velocity at spring peak tide through the Strait may exceed 3 m/s. This mainly results from the tidal phase-difference (180°) between the northern (Tyrrhenian Sea) and southern (Ionian Sea) tips of the Strait, associated with a difference of 0.27 m in tidal wave amplitudes. In addition, the complex coastline configuration of the Strait plays an important role in enhancing tidal current velocities. Therefore, the Strait of Messina fulfils the basic criterion (2 m/s tidal current velocity) to be considered as a valid tidal current energy resource. This massive tidal current energy resource is assessed in the present study. A detailed full desk-based Environmental Impact Assessment (EIA) study is performed using the interactive matrix approach in order to investigate the anticipated environmental impacts on the marine ecosystem of the Strait of Messina resulting from the harnessing of energy from its tidal currents. Through the EIA study the different environmental components, both biotic and abiotic, which may be affected by the energy extraction process, are explained. In addition, the proposed key project activities are listed; the likelihood of occurrence and the magnitude of impact interaction with the environmental components are evaluated. The final judgment matrix guides to make a right decision on the proposed project. From the resulted matrix, the major impacts do not exceed 10% of the total anticipated effects. The positive point is that all the expected impacts, including the majors, can be controlled and minimised to the lowest possible limits by applying a good monitoring programme. The University of Edinburgh “Tidal Flow Development (TFD)” numerical model is used to mimic the tidal environment of the Strait of Messina in different cases. The model successfully simulates the tidal flow regime within the Strait under some exceptional conditions. Modifications to the main numerical code and coefficients were necessary in the present research to adjust the model according to each case study. In the three different cases of simulation, using these exceptional coefficients, the model simulates the main tidal characteristics of the tidal flow within the Strait. According to the results of the numerical simulation process, tidal currents are more intensive close to the eastern coast of the Strait of Messina near to Punta Pezzo. This area is far from any ferry route between Italy and Sicily. The best location to deploy tidal turbines for the energy extraction process is therefore recommended to be within these surroundings. Finally, a physical (laboratory) model is used to simulate the flow regime within the Strait of Messina. The Particle Image Velocimetry (PIV) technique was applied in the flow-table tank at the University of Edinburgh. The physical model simulates the flow behaviour within the Strait of Messina to a satisfactory degree. The cyclonic and anti-cyclonic motions observed at the southern extremity of the Strait are also very well simulated. The results of the present study assure confidence in the use of tidal currents within the Strait of Messina as a renewable energy resource. The safety of the environment must be ensured by following environmental guidelines, respecting the energy extraction limits and by applying an effective monitoring programme. The later is strongly recommended to be an adaptive one in which higher environmental authorities are able to watch, revise and control the environmental team within the project. These authorities are also able to postpone the project in case of any severe environmental case. The simulation processes emphasize the effect of morphometry and topography in enhancing tidal currents in the Strait of Messina. Moreover, numerical simulation assures that the complex morphometry and bathymetry, in addition to the open boundaries of the Strait of Messina, are challenging issues for modellers in order to mimic the real tidal current resource in the case of the Strait of Messina. The study also strongly recommends applying a more effective numerical model than TFD to assess the tidal hydrodynamical environment before and after any proposed energy extraction process. This will certainly, with the EIA of the marine ecosystem, help to make a right decision about the proposed project in order to achieve the goal of using clean and clear renewable energy resources while maintaining both natural and hydrodynamical environments to the most possible safest degree.

Per tale strategie, la scrittrice usi il suo romanzo La casa nel vicolo, pubblicato nel 1920, “a puntate”, dalla rivista Nuova Antologia di Scienze, Lettere ed Arti, al fine di collaborare con la letteratura di consumo di cui il giornali e le riviste sono associati. Con tematiche prossime al cotidiano e al momento storico, i lettori si trovanno con i drami della vita, con la vittimizzazione dei essere e la opressione dell’individuo piú debole, in altre parole, le donne. Basando in questi fattori, le tecniche del “feuilleton” sarà necessario per comprovare la inserzione della opera della scrittrice siciliana, nel genere “feuilleton”. L'obiettivo di questo studio è quello di presentare le tecniche seriali che vengono utilizzate da Maria Messina nel suo romanzo La casa nel vicolo, in modo che rende visibile l'influenza del genere nel suo romanzo. / Na primeira fase do Novecentos literário italiano muitos folhetins franceses do século XIX foram reeditados por jornais italianos, alcançando grande sucesso de público, motivando Antonio Gramsci a encetar uma discussão em torno da inexistência de uma literatura “nacional-popular” italiana que traduzisse efetivamente as inquietações da época e as necessidades do povo, como tinha ocorrido na França. No entanto, desde 1900, o crítico literário Giuseppe Antonio Borgese vinha resenhando autores que publicavam romances à moda do folhetim francês nas páginas dos periódicos e das revistas italianas que naquele começo de século se multiplicavam e abriam suas páginas para um público mais amplo e diversificado, sobretudo, feminino. Atentos à chamada literatura de consumo, esses periódicos abriram espaço para a escrita feminina, ajudando a introduzir no cenário literário da época mulheres como Maria Messina, cujo romance de estréia, La casa nel vicolo, foi publicado em capítulos, à moda do “feuilleton” francês, nas páginas da revista Nuova Antologia de Lettere, Scienze ed Arti, em 1920. Nesta pesquisa, pretendemos identificar e enumerar as técnicas folhetinescas utilizadas por Maria Messina em La casa nel vicolo, de modo que se torne visível à influência do gênero em sua narrativa. / In the first phase of the Italian Novecento, many French 19th-century serials were reissued by Italian newspapers, reaching great success of audience, motivating Antonio Gramsci to enter into a discussion around the absence of a "national-popular" Italian literature which translates effectively the concerns and the needs of the people, as had occurred in France. However, since 1900, the literary critic Giuseppe Antonio Borgese had been reviewing authors who published French-style novels in the pages of periodicals and Italian magazines, which, at the beginning of the century multiplied and opened its pages to a broader and diverse audience, especially, female. Attentive to the consumer literature call, these periodicals have opened space for the writing women, helping to introduce in the literary scene of the time women like Maria Messina, whose debut novel, La casa nel vicolo, was published in chapters, like the French “feuilleton”, in the pages of the magazine Nuova Antologia de Lettere, Scienze ed Arti in 1920. The objective of this paper is to present the serial techniques that are used by the authoress in his novel La casa nel vicolo, so that becomes visible the influence of gender in his narrative.
