The great number of musical sources preserved in manuscript and printed form clearly reflects the prominent position held by the lute as a musical instrument during the sixteenth and early seventeenth centuries. Only a relatively small portion of this vast literature is presently available to scholars and interested laymen in the form of modern transcriptions. Referred to as "l'instrument noble par excellence," the lute's popular and fashionable appeal is evidenced by the large number of composers who dedicated themselves to this instrument. Among the number of outstanding lute composers living in Italy during the sixteenth and early seventeenth centuries was Giulio Cesare Barbetta (c. 1540-after 1603). During his lifetime Barbetta published a total of four books of lute pieces containing arrangements of polyphonic compositions of various Renaissance composers as well as a large number of original compositions including .preludes, airs, fantasias, and dance pieces. Although Barbetta achieved importance as a leading figure in the Italian school of lute composition, there is little readily available material, either biographical or musical; this study provides the scholar, the performer, and the listener with biographical data and a modern edition of the composer's complete works.

Ce travail de thèse s'articule autour d'une définition historique qui a été formulée par Cesare Pavese, lorsqu'il a défini les années 30 et 40 du XXe siècle comme les deux décennies de la traduction par excellence. Si les études menées jusqu'à aujourd'hui se sont penchées de manière approfondie presque seulement sur la traduction des romans et cela en choisissant comme langue source privilégiée l'anglais ou le français, nous avons concentré notre analyse sur la traduction, l'écriture et la critique poétiques réalisées dans la période s'étalant de l'entre-deux-guerres jusqu'à la fin des années 40. La poésie était en effet le lieu critique, traductif et créatif le plus fréquenté. Un véritable besoin de poésie animait les cénacles des intellectuels italiens à Florence comme à Milan, à Parme, à Rome et également à Turin. Les échanges entre les artistes, critiques, poètes et traducteurs se jouaient pour la plupart sur le terrain de la poésie, sans être, au moins jusqu'au milieu des années 30, particulièrement entravés par la censure fasciste. En effet l'Italie devait, même aux yeux du fascisme, connaître un Baudelaire, un Rimbaud et un Eliot parlant italien. La poésie prenait une place sans précédents dans la vie culturelle et littéraire de l'époque et devint aussi un champ d'action concret : écrire en vers bouleverse autant l'ordre syntactique de la langue que l'habitude à concevoir la réalité de manière univoque et sans opacités.La poésie, pour reprendre une pensée d'Henri Meschonnic, est « contre le maintien de l'ordre », et se propose comme une forme d'engagement profond qui implique les consciences et leur prise de position face à la réalité. Dans une perspective plus large, le discours poétique s'entrelace avec le discours politique, si par politique on présuppose tout effort visant à garantir le bien-être de l'homme et la création des conditions qui permettent la réalisation au degré le plus haut de la liberté de tout individu.L'objet d'intérêt de la traduction poétique fusionne inévitablement avec la poésie tout court, ne serait-ce que parce que toute poésie est en tout cas toujours une traduction. Faire et construire en poésie sont devenus ainsi les axes de cette étude qui essaye de rendre compte constamment des voix de plusieurs personnalités qui étaient à la fois poètes, traducteurs et critiques littéraires. La partie finale de ce travail se concentre ainsi sur la naissance d'un nouveau type d'intellectuel qui est poète, traducteur et critique, et qui, très souvent, est aussi un éditeur. Sa participation à la vie sociale, politique et éditoriale du pays devient de plus en plus significative et fera de la poésie le sujet de plusieurs collections éditoriales et de nombreuses autres publications.Nous avons essayé de montrer quel type d'engagement peut émaner de l'écriture des poèmes et de la pratique de la traduction poétique, en décrivant quel militantisme profond et passionné peut surgir de la 'fréquentation' de la poésie, qui se propose comme une constellation de sens constamment “constructible”, comme une présence jamais définitive. Cette mise en valeur de l'inachevé contribue à la mise en question de l'identité du sujet et à la poursuite de son salut, à la multiplication des hypothèses, et à l'ouverture des horizons. En se proposant avec son corps mouvant et émouvant, la poésie sera, pendant le fascisme, un levier d'indisciplinarité face à la règle, s'imposant comme un insoupçonnable instrument de contestation et de résistance. / This thesis focuses on a historical definition given by Cesare Pavese, when he defined the 30s and 40s of the twentieth century as the translation's period par excellence in Italy. The previous studies have looked extensively on the translation of novels and most of these researches choose English or French as principal language sources. This Phd thesis concentrates instead the analysis first of all on poetic translation and also on writing poetry as well as on poetic criticism ‘made' in the inter-war period until the late 40s. Poetry was incontestably the critical, translational and creative locus. Poetry was the main interest of the circles of Italian intellectuals in Florence and in Milan, in Parma, in Rome and in Turin also. Exchanges between artists, critics, poets and translators played mostly in the field of poetry, more or less without being particularly hampered by the fascist censorship, until the mid-30s. Poetry became a field of concrete action because it upsets language's syntactic order and this encourages a new conception and design of the reality, as well a way to fight every monolithic solution refusing opacity and incompleteness.Using an expression of Henri Meschonnic poetry is “against the maintenance of the order”, and presents itself as a form of deep commitment (in order words a form of “engagement”) that involves awareness and taking a stand against reality. In a poetic discourse the political element is closed involved. In fact we assume that “politics” is any attempt to fight for the welfare of man and every attempt to achieve the highest degree of freedom of every individual.The subject of criticism and translating poetry inevitably merge with poetry at all, and it is to consider that poetry is in any case always a translation. Poetry and its effects have become the axes of this study that tries to present consistently the voices of several people who were poets, translators and literary critics at the same time. The final part of this work concentrates on the birth of a new type of intellectual who is a poet, a translator, a critic and often also a publisher.We tried to show also what type of engagement may trigger the writing of poems and the practice of poetic translation, describing how deep and passionate activism may arise 'attending' poetry. Poetry is always proposed as a constellation of meaning constantly "building" as a presence never definitive. This enhancement of the unfinished contributes to the questioning of the subject's identity and to the pursuit of his salvation. Every poetic multiplication of hypotheses allows the opening of a lot of horizons. Offering her moving body poetry has been, even during Fascism, a lever of great indisciplinarity face to the rule settled by the dictatorship and it has been an unsuspected instrument of protest and resistance.

Mon travail de thèse porte sur la « Scapigliatura democratica », un mouvement littéraire italien qui se développa à Milan entre les années 60 et 80 du XIXe siècle. Par rapport au plus large mouvement de la « Scapigliatura », la « Scapigliatura democratica » se caractérise par le lien étroit entre littérature et politique qui est à la base de son projet culturel. Mon étude a pour objectif d’analyser ce phénomène de politisation dans la production narrative et journalistique des représentants les plus significatifs du mouvement (Arrighi, Bizzoni, Tronconi, Valera, Cameroni).Après un chapitre introductif sur l’état de l’art concernant ce sujet, la thèse s’articule en deux parties principales. Dans la première, nous avons cherché à donner une description du rapport entre « Scapigliatura » et politique de la fin des années 1850, au moment où le terme « Scapigliatura » paraît pour la première fois dans le fragment signé par Cletto Arrighi La scapigliatura, jusqu’à « La Farfalla » de Angelo Sommaruga, un des derniers journaux liées au mouvement ; en passant aussi par l’expérience cruciale du « Gazzettino Rosa » (1867-1873) de Achille Bizzoni et Felice Cavallotti. Afin d’éviter toute confusion terminologique avec les études critiques précédentes, nous avons privilégié les usages du mot « Scapigliatura » qui venaient de l’intérieur du mouvement, notamment des articles-manifestes à la première personne que l’on retrouve souvent dans les journaux « scapigliati » de l’époque. En ce sens, une des tâches principales de notre travail à été d’évaluer, selon l’auteur ou le journal concerné, l’évolution et le différent degré de politisation du terme.Dans la deuxième partie, en revanche, l’objectif a été d’étudier en parallèle la production littéraire et journalistique du mouvement, en essayant d’en montrer la contiguïté aussi bien au niveau formel qu’au niveau de contenus. L’hypothèse que nous avons voulu vérifier, en particulier, est qu’un même courant « pamphlétaire » (Angenot, La parole pamphlétaire, 1982) traverse l’ensemble de cette production, tous genres littéraires ou pragmatiques confondus. Il en découle que le trait distinctif de la « Scapigliatura democratica » réside moins dans sa configuration artistique ou littéraire que dans sa disposition rhétorique. A cet égard, nous avons montré que même la tendance littéraire du réalisme, majoritaire au sein du mouvement, se caractérise dans son application concrète par la forte influence de catégories éthiques et idéologiques qui sont extralittéraires. Dans le dernier chapitre de cette partie, nous avons mis à l’épreuve cette idée de littérature hybride en analysant quelques-unes parmi les batailles à la fois culturelles et politiques menées par le mouvement tout au long de son activité, comme celles concernant le militarisme, la morale bourgeoise ou la question sociale dans l’univers urbain.En conclusion, nous avons souligné l’importance de la réflexion politique dans la construction de l’identité du mouvement, ainsi que le rôle novateur d’intellectuel-agitateur que les écrivains-journalistes « scapigliati » eurent dans la crise politique et culturelle de l’Italie de premières années après l’Unité. Cela se fit notamment par la proposition d’une littérature de combat qui allait montrer toute sa puissance et sa capacité d’incidence sur la société à partir de la fin du XIXe siècle. / My thesis work focuses on the “Scapigliatura democratica”, an Italian literary movement that developed in Milan between the 60s and 80s of the 19th century. Compared to the broader Scapigliatura movement, the Scapigliatura democratica is characterized by the close link between literature and politics that underlies its cultural project. My research aimed to investigate this phenomenon of politicization in the narrative and journalistic production of the most significant representatives of the movement (Arrighi, Bizzoni, Tronconi, Valera, Cameroni).After an introductory chapter on the state of the art, the thesis is divided into two main parts. In the first, we sought to describe the relationship between “Scapigliatura” and politics, from the late 1850s, when the term “Scapigliatura” first appeared in Cletto Arrighi’s fragment La scapigliatura, to the journal called «La Farfalla» by Angelo Sommaruga, one of the last newspapers linked to the movement; and also passing through the crucial experience of «Gazzettino Rosa» (1867-1873) by Achille Bizzoni and Felice Cavallotti. In order to avoid any terminological confusion with previous critical studies, we favoured the use of the word “Scapigliatura” from within the movement, in particular the articles written in the first person that were often published in the “scapigliati” journals of the time. In this sense, one of the main tasks of our work has been to evaluate, according to the author or journal concerned, the evolution and the different degree of politicization of the term.In the second part, our goal has been to show the contiguity between literary production and the journalistic activity of the movement, both formally and in terms of content. The hypothesis we wanted to verify was, in particular, the presence of some features related to the pamphlet genre (Angenot, La parole pamphlétaire, 1982) in all this production. It follows that the distinctive feature of the “Scapigliatura democratica” lies less in its artistic or literary configuration than in its rhetorical disposition. In this respect, we shown that even the literary trend of realism, which is the majority within the movement, is characterized in its concrete application by the strong influence of extraliterary ethical and ideological categories. In the last chapter of this section, we tested this idea of hybrid literature by analyzing some of the battles, both cultural and political, waged by the movement throughout its activity, such as those concerning militarism, bourgeois morality or the social question.In conclusion, we underlined the importance of political reflection in building the identity of the movement, as well as the innovative role of intellectual-agitator that the “scapigliati” writer-journalists had in Italy’s political and cultural crisis in the first years after Unity. This was done in particular by the proposal of a combat literature, which would show all its power and its capacity to have an impact on society from the end of the 19th century onwards.

This study investigates the woodcuts of African dress in Cesare Vecellio's 1598 costume book Habiti antichi et moderni di tutto il mondo. While Vecellio's book has been previously studied to understand its contribution to sixteenth-century conceptions of human variation across geography and Venetian identity making, I concentrate instead on the book's intended function. In doing so, I show how its woodcuts of Africans, should be understood primarily as proposals for costumes to be used in new artistic productions. Vecellio situated his representations of African costume in a highly organized geographic framework that was shaped by travel narratives. These texts recorded voyages motivated, in part, by European political and economic interests in Africa. However, the resulting associations deposited in Vecellio's woodcuts are neutralized or at least complicated by the representations' hybridity, their inclusion in an early modern collection, and their status as models for artists to manipulate. Vecellio explained that all of the representations in Habiti antichi et moderni di tutto il mondo displayed antiquity (antichità), diversity (diuersità), and richness (la richezza). Sixteenth-century theater directors insisted on these qualities for costume, which promoted both the imitatio naturae and superatio naturae of artistic productions. Costumes could simultaneously contribute to a painting or a theatrical performance's decorum and propriety by differentiating and correctly identifying figures, and its grazia or pleasure with their exoticism and sumptuousness. This study suggests that in their intended use, the images of African costume were participating in "translations" of African dress into costumes for European paintings and theater. During this process, they accumulated new meanings. The dressed figures were copied from art objects with varying degrees of removal from immediate African encounters and combined with texts from published travel narratives to create mythic bricolages of Africans. The decontextualized costumes, organized into a sartorial collection with a categorization that readers understood as flexible, were tentatively defined vestmentary signs available for further signification within potential artistic contexts.

Over the last few decades, the world has witnessed rapid urbanisation. One of the many complex problems resulting from increased urbanisation is related to management of stormwater from developed areas. If stormwater is not managed properly, it may lead to flooding of urban areas, and deterioration of water quality in rivers and receiving waters. Urban drainage systems are used to manage urban stormwater. For design of effective and economic urban drainage systems, it is important to estimate the design flows accurately. Many computer based mathematical models have been developed to study catchment runoff (or flows) in urban environments. These models may be used in different stages of the projects such as screening, planning, design and operation. Each stage may require a different model, although some models can be used for several of these stages. A customer survey was conducted in May 1997 to study the current practice in Victoria (Australia) on stormwater drainage design and analysis, as part of this thesis. The survey was restricted to city/shire councils and consultants, who are engaged in design and analysis of urban drainage systems. The results of the survey showed that 95% of respondents used the Statistical Rational method. Also, it was revealed that most respondents were reluctant to use stormwater drainage computer models, since there were no adequate guidelines and information available to use them especially for ungauged catchments. According to 5% of the respondents, who used models, ILSAX was the most widely used stormwater drainage computer model in Victoria. The 1987 edition of the Australian Rainfall-Runoff (ARR87) suggests the ILSAX model as one of the computer models that can be used for stormwater drainage design and analysis. Due to these reasons, the ILSAX model was used in this study in an attempt to produce further guidance to users in development and calibration of ILSAX models of urban drainage systems. In order to use the ILSAX model, it is necessary to estimate the model parameters for catchments under consideration. The model parameters include loss model parameters (i.e. infiltration and depression storage parameters) and other parameters related to the catchment (such as percent imperviousness, soil cover and conveyance system parameters). Some of these parameters can be estimated from available maps and drawings of the catchment. The ideal method to determine these parameters (which cannot be reliably determined from available maps and drawings) is through calibration of these models using observed rainfall and runoff data. However, only few urban catchments are monitored for rainfall and runoff, and therefore calibration can be done only for these catchments. At present, there are no clear guidelines to estimate the model parameters for ungauged catchments where no rainfall-runoff data are available. In this PhD project, first the ILSAX model was calibrated for some gauged urban catchments. From the results of calibration of these catchments, regression equations were developed to estimate some model parameters for use in gauged and ungauged urban stormwater catchments. Before calibrating the ILSAX model for gauged catchments, a detailed study was conducted to; - select the most appropriate modelling option (out of many available in ILSAX) for modelling various urban drainage processes, - study the sensitivity of model parameters on simulated storm hydrographs, and - study the effect of catchment subdivision on storm hydrographs. This detailed study was conducted using two typical urban catchments (i.e. one 'small' and one 'large') in Melbourne metropolitan area (Victoria) considering four design storms of different average recurrence intervals (ARI). Three storms with ARI of 1, 10 and 100 years, and one with ARI greater than 100 years were considered in the study. The results obtained from this detailed study were subsequently used in model calibration of the study catchments. The results showed that the runoff volume of 'large' storm events was more sensitive to the antecedent moisture condition and the soil curve number (which determines soil infiltration) and less sensitive to the pervious and impervious area depression storages. However, for 'small' storm events, the runoff volume was sensitive to the impervious area depression storage. The peak discharge was sensitive to pipe roughness, pit choke factor, pit capacity parameters and gutter characteristics for both 'small' and 'large' storm events. The results also showed that the storm hydrograph was sensitive to the catchment subdivision. The accuracy of rainfall-runoff modelling can be adversely influenced by erroneous input data. Therefore, the selection of accurate input data is crucial for development of reliable and predictive models. In this research project, a number of data analysis techniques were used to select good quality data for model calibration. For calibration of model parameters, parameter optimisation was preferred to the trial and error visual comparison of observed and modelled output responses, due to subjectivity and time-consuming nature of the latter approach. It was also preferred in this study, since the model parameters obtained from calibration were used in the development of regional equations for use in gauged and ungauged catchments. Therefore, it was necessary to have a standard method which can be repeated, and produced the same result when the method is applied at different times for a catchment. An optimisation procedure was developed in this thesis, to estimate the model parameters of ILSAX. The procedure was designed to produce the 'best' set of model parameters that considered several storm events simultaneously. The PEST computer software program was used for the parameter optimisation. According to this procedure, the impervious area parameters can be obtained from frequent 'small' storm events, while the pervious area parameters can be obtained from less-frequent 'large' storm events. Twenty two urban catchments in the Melbourne metropolitan area (Victoria) were considered in the model parameter optimisation. Several 'small' and 'large' storm events were considered for each catchment. However, it was found during the analysis that the selected 'large' storm events did not produce any pervious area runoff, and therefore it was not possible to estimate the pervious area parameters for these catchments. The Giralang urban catchment in Canberra (Australia) was then selected to demonstrate the optimisation procedure for estimating both impervious and pervious area parameters, since data on 'small' and 'large' storm events were available for this catchment. The calibration results were verified using different sets of storm events, which were not used in the calibration, for all catchments. The optimised model parameters obtained for each catchment were able to produce hydrographs similar to the observed hydrographs, during verification. The impervious area parameters obtained from optimisation agreed well with the information obtained from other sources such as areal photographs, site visits and published literature. Similarly, the pervious area parameters obtained for the Giralang catchment agreed well with the values given in the published literature. If ILSAX is to be used for ungauged drainage systems for which no storm data are available, then the model parameters have to be estimated by some other means. One method is to estimate them through regional equations, if available. These regional equations generally relate the model parameters to measurable catchment properties. In this study, analyses were conducted to develop such regional equations for use in ungauged residential urban catchments in the Melbourne metropolitan area. The Melbourne metropolitan area was considered as one hydrologically homogeneous group, since the urban development is similar in the area. The equations were developed for the land-use parameters of directly connected impervious area percentage (DCIA) and supplementary area percentage (SA), and the directly connected impervious area depression storage (DSi). Several influential catchment parameters such as catchment area, catchment slope, distance from the Central Business District to the catchment and household density were considered as independent variables in these regional equations. A regional equation was developed for DCIA as a function of the household density. A similar equation was also developed to determine SA as a function of household density. DCIA was obtained from the model parameter optimisation using rainfall-runoff data (i.e. calibration), while SA and household density were obtained from the available drawings and field visits. These two equations showed a very good correlation with household density and therefore, DCIA and SA can be estimated accurately using these two equations. The city/shire councils generally have information on the household density in already developed urban areas and therefore, these two equations can be used to estimate DCIA and SA for these areas. For new catchments, these equations can be used to estimate DCIA and SA based on the proposed household density. The directly connected impervious area depression storage (DSi) is the only ILSAX model loss parameter that was obtained from the calibration, and this is the loss parameter that is more sensitive for 'small' storm events of the urban drainage catchments. A regional equation was attempted for this parameter by relating with the catchment slope, since the catchment slope was found to have some correlation with DSi according to past studies. However, the results in this study did not show a correlation between these two variables. Therefore, based on the results of this study, a range of 0 - 1 mm was recommended for DSi. Because of the recommended range for DSi, the sensitivity of DSi against DCIA was revisited and found that DSi was less sensitive compared to DCIA, in simulating the peak discharge and time to peak discharge for both 'small' and 'large' storm events. However, there is a little impact for runoff volume and hydrograph shape for 'small' storm events. Therefore, defining a range for DSi is justified for modelling purposes and the user can choose a suitable value within this range from engineering judgement.

Packaging plays an important role in protecting and preserving the quality of food and is therefore significant in any food manufacturing and distribution process. The shelf life of any food is limited due to the occurrence of many deteriorative processes and reactions within the food material. These include physical and chemical reactions and interactions between food and the ambient environment across the packaging material. Milk powder like any other food, is prone to such reactions and interactions with package resulting in degradation of its edible quality due to changes in smell, colour and texture, which ultimately renders it nutritionally and economically unacceptable. During distribution and storage the packaging system needs to stabilize the powder by ensuring optimum storage conditions are maintained. To ensure maximum shelf life it is essential to apply packaging systems that are optimally designed, to meet the requirements with respect to manufacturing as well as product protection in the distribution environment. In this thesis, the interactions between ambient environmental conditions, packaging material properties and the shelf life of a particular filled milk powder were investigated. Consequently, the requirements for a packaging system that can provide a two-year shelf life for the powder were determined. The filled milk powder is manufactured and packaged in bulk in Europe, imported into Africa via sea freight containers to be repacked into small portion packs and distributed in multiple African countries. Because of Africa's tropical conditions the packaged product is exposed to rather high levels of relative humidity and temperature during transportation and storage which influences the stability of the powder. The storage stability of the filled milk powder along with the barrier characteristics of the packaging was assessed in order to evaluate the theoretical shelf life of the powder in its current packaging system.

A 'spray and hay' method was developed which replaces the noxious weed serrated tussock (Nassella trichotoma (Nees) Arech.) with indigenous kangaroo grass (Themeda triandra Forrsk.) in partly disturbed remnants of western (basalt) plains indigenous grassland, a community listed as vulnerable to extinction. Investigations were carried out on Melbourne's north-west urban fringe. Refinements of the 'spray and hay' method resulted in low densities of other weeds amongst the newly established T. triandra swards. First steps in the method involved removal of weeds by slashing and follow-up treatment with either of the herbicides, glyphosate (as Monsanto Roundup®) or atrazine (as Nufarm Nutrazine®). These steps resulted in close to 100% kill of mature N. trichotoma plants. Greater than 98% replacement of N. trichotoma with T. triandra was achieved by thatching over herbicide-treated plots with seed-bearing T. triandra hay harvested from remnant grasslands and then removal of the hay several months later by either burning or physical removal. The type and timing of herbicide application, thatching and removal of thatch were found to be central for successfully establishing competitive densities of T. triandra seedlings and minimizing re-establishment of N. trichotoma and other weed seedlings. A treatment set involving: slashing weed biomass in summer (January), herbicide application in autumn (April) followed by thatching with seed-bearing T. triandra hay in winter (July) and removal of thatch in spring (October) produced the best results. Assessing the seed content of hay and germinability of seed prior to revegetation were also important for calculating the amount of hay laid and subsequent seedling densities established. The seed content and germinability of seed-bearing hay was found to vary markedly in samples harvested in three different years, across discrete remnant grassland sites and even within undisturbed grassland sites. Reasons for the success of the method, and why other variations are less successful are discussed, as is the wider application of the method for weed control and replacement with indigenous grasses in lowland grassland remnants.
