Design and development of new pressure sensors for aerodynamic applications

This artwork reports on two different projects that were carried out during the three years of Doctor of the Philosophy course. In the first years a project regarding Capacitive Pressure Sensors Array for Aerodynamic Applications was developed in the Applied Aerodynamic research team of the Second Faculty of Engineering, University of Bologna, Forlì, Italy, and in collaboration with the ARCES laboratories of the same university. Capacitive pressure sensors were designed and fabricated, investigating theoretically and experimentally the sensor’s mechanical and electrical behaviours by means of finite elements method simulations and by means of wind tunnel tests. During the design phase, the sensor figures of merit are considered and evaluated for specific aerodynamic applications. The aim of this work is the production of low cost MEMS-alternative devices suitable for a sensor network to be implemented in air data system. The last two year was dedicated to a project regarding Wireless Pressure Sensor Network for Nautical Applications. Aim of the developed sensor network is to sense the weak pressure field acting on the sail plan of a full batten sail by means of instrumented battens, providing a real time differential pressure map over the entire sail surface. The wireless sensor network and the sensing unit were designed, fabricated and tested in the faculty laboratories. A static non-linear coupled mechanical-electrostatic simulation, has been developed to predict the pressure versus capacitance static characteristic suitable for the transduction process and to tune the geometry of the transducer to reach the required resolution, sensitivity and time response in the appropriate full scale pressure input A time dependent viscoelastic error model has been inferred and developed by means of experimental data in order to model, predict and reduce the inaccuracy bound due to the viscolelastic phenomena affecting the Mylar® polyester film used for the sensor diaphragm. The development of the two above mentioned subjects are strictly related but presently separately in this artwork.

Rafael Moneo: la complessità del vuoto. Dalle matrici formali dell'opera di Oteiza e Chillida

The experience of void, essential to the production of forms and to make use them, can be considered as the base of the activities that attend to the formative processes. If void and matter constitutes the basic substances of architecture. Their role in the definition of form, the symbolic value and the constructive methods of it defines the quality of the space. This job inquires the character of space in the architecture of Moneo interpreting the meaning of the void in the Basque culture through the reading of the form matrices in the work of Jorge Oteiza and Eduardo Chillida. In the tie with the Basque culture a reading key is characterized by concurring to put in relation some of the theoretical principles expressed by Moneo on the relationship between place and time, in an unique and specific vision of the space. In the analysis of the process that determines the genesis of the architecture of Moneo emerges a trajectory whose direction is constructed on two pivos: on the one hand architecture like instrument of appropriation of the place, gushed from an acquaintance process who leans itself to the reading of the relations that define the place and of the resonances through which measuring it, on the other hand the architecture whose character is able to represent and to extend the time in which he is conceived, through the autonomy that is conferred to them from values. Following the trace characterized from this hypothesis, that is supported on the theories elaborated from Moneo, surveying deepens the reading of the principles that construct the sculptural work of Oteiza and Chillida, features from a search around the topic of the void and to its expression through the form. It is instrumental to the definition of a specific area that concurs to interpret the character of the space subtended to a vision of the place and the time, affine to the sensibility of Moneo and in some way not stranger to its cultural formation. The years of the academic formation, during which Moneo enters in contact with the Basque artistic culture, seem to be an important period in the birth of that knowledge that will leads him to the formulation of theories tied to the relationship between time, place and architecture. The values expressed through the experimental work of Oteiza and Chillida during years '50 are valid bases to the understanding of such relationships. In tracing a profile of the figures of Oteiza and Chillida, without the pretension that it is exhaustive for the reading of the complex historical period in which they are placed, but with the needs to put the work in a context, I want to be evidenced the important role carried out from the two artists from the Basque cultural area within which Moneo moves its first steps. The tie that approaches Moneo to the Basque culture following the personal trajectory of the formative experience interlaces to that one of important figures of the art and the Spanish architecture. One of the more meaningful relationships is born just during the years of his academic formation, from 1958 to the 1961, when he works like student in the professional office of the architect Francisco Sáenz de Oiza, who was teaching architectural design at the ETSAM. In these years many figures of Basque artists alternated at the professional office of Oiza that enjoys the important support of the manufacturer and maecenas Juan Huarte Beaumont, introduced to he from Oteiza. The tie between Huarte and Oteiza is solid and continuous in the years and it realizes in a contribution to many of the initiatives that makes of Oteiza a forwarder of the Basque culture. In the four years of collaboration with Oiza, Moneo has the opportunity to keep in contact with an atmosphere permeated by a constant search in the field of the plastic art and with figures directly connected to such atmosphere. It’s of a period of great intensity as in the production like in the promotion of the Basque art. The collective “Blanco y Negro”, than is held in 1959 at the Galería Darro to Madrid, is only one of the many times of an exhibition of the work of Oteiza and Chillida. The end of the Fifties is a period of international acknowledgment for Chillida that for Oteiza. The decade of the Fifties consecrates the hypotheses of a mythical past of the Basque people through the spread of the studies carried out in the antecedent years. The archaeological discoveries that join to a context already rich of signs of the prehistoric era, consolidate the knowledge of a strong cultural identity. Oteiza, like Chillida and other contemporary artists, believe in a cosmogonist conception belonging to the Basques, connected to their matriarchal mythological past. The void in its meaning of absence, in the Basque culture, thus as in various archaic and oriental religions, is equivalent to the spiritual fullness as essential condition to the revealing of essence. Retracing the archaic origins of the Basque culture emerges the deep meaning that the void assumes as key element in the religious interpretation of the passage from the life to the death. The symbology becomes rich of meaningful characters who derive from the fact that it is a chthonic cult. A representation of earth like place in which divine manifest itself but also like connection between divine and human, and this manipulation of the matter of which the earth it is composed is the tangible projection of the continuous search of the man towards God. The search of equilibrium between empty and full, that characterizes also the development of the form in architecture, in the Basque culture assumes therefore a peculiar value that returns like constant in great part of the plastic expressions, than in this context seem to be privileged regarding the other expressive forms. Oteiza and Chillida develop two original points of view in the representation of the void through the form. Both use of rigorous systems of rules sensitive to the physics principles and the characters of the matter. The last aim of the Oteiza’s construction is the void like limit of the knowledge, like border between known and unknown. It doesn’t means to reduce the sculptural object to an only allusive dimension because the void as physical and spiritual power is an active void, that possesses that value able to reveal the being through the trace of un-being. The void in its transcendental manifestation acts at the same time from universal and from particular, like in the atomic structure of the matter, in which on one side it constitutes the inner structure of every atom and on the other one it is necessary condition to the interaction between all the atoms. The void can be seen therefore as the action field that concurs the relations between the forms but is also the necessary condition to the same existence of the form. In the construction of Chillida the void represents that counterpart structuring the matter, inborn in it, the element in absence of which wouldn’t be variations neither distinctive characters to define the phenomenal variety of the world. The physics laws become the subject of the sculptural representation, the void are the instrument that concurs to catch up the equilibrium. Chillida dedicate himself to experience the space through the senses, to perceive of the qualities, to tell the physics laws which forge the matter in the form and the form arranges the places. From the artistic experience of the two sculptors they can be transposed, to the architectonic work of Moneo, those matrices on which they have constructed their original lyric expressions, where the void is absolute protagonist. An ambit is defined thus within which the matrices form them drafts from the work of Oteiza and Chillida can be traced in the definition of the process of birth and construction of the architecture of Moneo, but also in the relation that the architecture establishes with the place and in the time. The void becomes instrument to read the space constructed in its relationships that determine the proportions, rhythms, and relations. In this way the void concurs to interpret the architectonic space and to read the value of it, the quality of the spaces constructing it. This because it’s like an instrument of the composition, whose role is to maintain to the separation between the elements putting in evidence the field of relations. The void is that instrument that serves to characterize the elements that are with in the composition, related between each other, but distinguished. The meaning of the void therefore pushes the interpretation of the architectonic composition on the game of the relations between the elements that, independent and distinguished, strengthen themselves in their identity. On the one hand if void, as measurable reality, concurs all the dimensional changes quantifying the relationships between the parts, on the other hand its dialectic connotation concurs to search the equilibrium that regulated such variations. Equilibrium that therefore does not represent an obtained state applying criteria setting up from arbitrary rules but that depends from the intimate nature of the matter and its embodiment in the form. The production of a form, or a formal system that can be finalized to the construction of a building, is indissolubly tied to the technique that is based on the acquaintance of the formal vocation of the matter, and what it also can representing, meaning, expresses itself in characterizing the site. For Moneo, in fact, the space defined from the architecture is above all a site, because the essence of the site is based on the construction. When Moneo speaks about “birth of the idea of plan” like essential moment in the construction process of the architecture, it refers to a process whose complexity cannot be born other than from a deepened acquaintance of the site that leads to the comprehension of its specificity. Specificity arise from the infinite sum of relations, than for Moneo is the story of the oneness of a site, of its history, of the cultural identity and of the dimensional characters that that they are tied to it beyond that to the physical characteristics of the site. This vision is leaned to a solid made physical structure of perceptions, of distances, guideline and references that then make that the process is first of all acquaintance, appropriation. Appropriation that however does not happen for directed consequence because does not exist a relationship of cause and effect between place and architecture, thus as an univocal and exclusive way does not exist to arrive to a representation of an idea. An approach that, through the construction of the place where the architecture acquires its being, searches an expression of its sense of the truth. The proposal of a distinction for areas like space, matter, spirit and time, answering to the issues that scan the topics of the planning search of Moneo, concurs a more immediate reading of the systems subtended to the composition principles, through which is related the recurrent architectonic elements in its planning dictionary. From the dialectic between the opposites that is expressed in the duality of the form, through the definition of a complex element that can mediate between inside and outside as a real system of exchange, Moneo experiences the form development of the building deepening the relations that the volume establishes in the site. From time to time the invention of a system used to answer to the needs of the program and to resolve the dual character of the construction in an only gesture, involves a deep acquaintance of the professional practice. The technical aspect is the essential support to which the construction of the system is indissolubly tied. What therefore arouses interest is the search of the criteria and the way to construct that can reveal essential aspects of the being of the things. The constructive process demands, in fact, the acquaintance of the formative properties of the matter. Property from which the reflections gush on the relations that can be born around the architecture through the resonance produced from the forms. The void, in fact, through the form is in a position to constructing the site establishing a reciprocity relation. A reciprocity that is determined in the game between empty and full and of the forms between each other, regarding around, but also with regard to the subjective experience. The construction of a background used to amplify what is arranged on it and to clearly show the relations between the parts and at the same time able to tie itself with around opening the space of the vision, is a system that in the architecture of Moneo has one of its more effective applications in the use of the platform used like architectonic element. The spiritual force of this architectonic gesture is in the ability to define a place whose projecting intention is perceived and shared with who experience and has lived like some instrument to contact the cosmic forces, in a delicate process that lead to the equilibrium with them, but in completely physical way. The principles subtended to the construction of the form taken from the study of the void and the relations that it concurs, lead to express human values in the construction of the site. The validity of these principles however is tested from the time. The time is what Moneo considers as filter that every architecture is subordinate to and the survival of architecture, or any of its formal characters, reveals them the validity of the principles that have determined it. It manifests thus, in the tie between the spatial and spiritual dimension, between the material and the worldly dimension, the state of necessity that leads, in the construction of the architecture, to establish a contact with the forces of the universe and the intimate world, through a process that translate that necessity in elaboration of a formal system.

Retorica e mito in Giambattista Vico

The purpose of this thesis is to show that Vico had the constant aim, remained unaltered in time, to support the usefulness of Rhetoric. The awareness of the strength acquired by the “anti-rhetorical” movements, particularly by the Cartesians and the Logicians from Port-Royal, obliged Vico to elaborate some strategies and counter-moves that, little by little, became more and more complex and refined, till they inspired his main work, The New Science. By taking into consideration the most significant aspects of Vico’s speculation (topic, tropes, the formation of language, the development of human thought, the new conception of philology ), this work shows that they are part of a strategy worked out by the Neapolitan philosopher, in order to demonstrate the validity, the usefulness and the modernity of Rhetoric. Every aspect of Vico’s thought reaches its peak when Vico formulates his theory about myths, which he interprets as an expression of the primitive man’s necessities and demands. The point of view expressed by this doctorate thesis emphasizes that, despite the inevitable modifications that have taken place through the centuries, Vico’s thought keeps its substantial unity. So those subjects that critical literature tends to separate are, in reality, linked and unified.

La scuola di Gundēšābūr. La conoscenza del corpo umano (anatomia e fisiologia) e la trasmissione delle teorie medico-scientifiche nel mondo sasanide e post-sasanide.

Questo lavoro traccia un quadro della diffusione e trasmissione delle conoscenze riguardanti l’anatomia e la fisiologia del corpo umano nel mondo iranico in età sasanide (III-VII sec. d.C.). La tesi analizza il ruolo delle scuole di medicina in territorio iranico, come quelle sorte a Nisibi e Gundēšābūr, delle figure dei re sasanidi interessati alla filosofia e alla scienza greca, e dei centri di studio teologico e medico che, ad opera dei cristiani siro-orientali, si fecero promotori della conoscenza medico-scientifica greca in terra d’Iran.

I manoscritti miniati dell'Illustratore nella cultura figurativa del secondo quarto del XIV secolo

La tesi è dedicata alla personalità artistica dell’Illustratore, tra i protagonisti della miniatura bolognese degli anni trenta e quaranta del Trecento, così felicemente soprannominato da Roberto Longhi. Dopo un capitolo dedicato alla vicenda critica dell’artista, la tesi affronta il percorso artistico dell’Illustratore nell’ambito della decorazione libraria bolognese del secondo quarto del XIV secolo. Ho trattato le opere attribuite al’Illustratore insieme agli esempi contemporanei della miniatura bolognese, in modo da far emergere il ruolo di questo maestro nelle relazioni con il contesto cittadino. Nella successione cronologica dei manoscritti, emerge un nuovo sconvolgimento caotico che scardina l’ordine spaziale e compositivo delle opere iniziali debitrici del giottismo del Maestro del 1328. Il capitolo si conclude con alcune osservazioni sui rapporti tra il maestro e i suoi aiuti e sul rapporto con Buffalmacco. In questo capitolo sono inoltre presentate due nuove attribuzioni. Gli ultimi due capitoli sono un approfondimento sull’interazione tra il linguaggio figurativo dell’artista e la funzione dell’immagine quale forma di comunicazione visiva in stretta relazione con i testi scritti che accompagnano e sui caratteri della committenza, là dove è possibile definirli. La prima parte del terzo capitolo è dedicata all’illustrazione dei libri legales, mentre nella seconda parte si tratta di un caso particolare, le iniziali istoriate dell’Inferno e del Purgatorio di Dante Alighieri della Biblioteca Riccardiana di Firenze (ms. 1005), per molti aspetti riconducibili all’illustrazione giuridica. La mia intenzione in questo capitolo è di verificare come il caratteristico linguaggio narrativo espressivo e diretto dell’Illustratore abbia risposto alla funzione delle immagini dipinte nei codici giuridici di offrire una struttura materiale alla memorizzazione visiva per via di luoghi e figure dei contenuti di studio del diritto comune. In appendice alla tesi si trova un catalogo dei manoscritti decorati da miniature dell’Illustratore, comprensivo anche di una sezione per le opere di dubbia o erronea attribuzione.

La canzone sociale in Italia e in Francia tra protesta, nazione e rivoluzione (1830-1870)

La tesi di ricerca si propone di esaminare due tipologie della canzone sociale nel XIX secolo, ed in particolare attorno al 1848. Lo studio del canto nei contesti presi in esame (l’Italia e la Francia) viene analizzato attraverso due piste di ricerca parallele tra loro. Da una parte si è utilizzato il concetto di sociabilité per conoscere i luoghi di produzione e di diffusione del canto (l’importanza della strada, dell’osteria, delle goguette parigine, degli chansonniers des rues e dei cantastorie) e le circostanze di utilizzazione della canzone (la canzone in quanto forma d’espressione orale ma anche come scrittura murale, foglio volante e volantino). Dall’altra l’analisi si è focalizzata sui contenuti dei testi musicali per mette in luce le differenti tematiche, le immagini linguistiche e le figure retoriche cantate dall’artigiano-operaio per far emergere le differenze dell’idea di nazione tra i due contesti presi in esame. L’attenzione posta alla comparazione condurrà all’evidenziazione di punti di contatto tra le due nazioni. Il canto, infatti, costituisce un terreno privilegiato per comprendere l’immagine dell’“altro”: quale immagine possedevano i lavoratori francesi dell’Italia risorgimentale? E gli artigiani italiani come percepivano la nazione francese? Il canto viene analizzato non solamente come un “testo” ma anche come una “pratica sociale”. Queste operazioni permetteranno di sondare più in profondità la funzione sociale svolta dalla canzone all’interno della cultura popolare e la sua importanza in quanto forma d’espressione e vettore di politicizzazione. La duplice utilizzazione del canto, in quanto “testo” e “pratica”, consente di inserire la ricerca all’interno di un filone storiografico che dalla storia sociale si muove a quella culturale. La canzone sociale rappresenta un fertile terreno di ricerca, non solamente all’interno di un singolo territorio nazionale, ma possiede un prezioso valore euristico in funzione comparativa.

«L’impero portatile» dei portoghesi: articolazione e figure narrative nell’immaginario coloniale portoghese.

A partire da una ricognizione storica sull’ultimo impero coloniale portoghese, la tesi intende analizzare come il mito dell’impero abbia contribuito a definire l’identità nazionale del Portogallo e il suo patrimonio culturale e letterario. Il mito viene indagato in particolar modo nella sua componente linguistica e discorsiva, come modalità peculiare di costruire “costellazioni” di immagini. In questo contesto la letteratura assume una rilevanza specifica, poiché le sue risorse formali le permettono di contrapporre alla fissità del mito una potente articolazione in grado di scardinare gli automatismi legati ad una translatio imperii volta a reiterare l’immaginazione del centro. L’analisi di un corpus letterario afferente a quella che potremmo chiamare la letteratura “dei retornados”, che si concentra soprattutto sulla definizione della focalizzazione narrativa e sulla rielaborazione delle figure narrative, intende ricercare le diverse forme di assumere criticamente il canone imperiale e di oltrepassarlo.

Tracce di cinefilia su Facebook

La mia tesi approfondisce le dinamiche della cinefilia su Facebook: quali relazioni s'instaurano tra lo spettatore cinefilo, e dunque il suo particolare sguardo, e la moltitudine di frammenti di cinema dispersi nella rete; come si sono modificati i rapporti, gli atteggiamenti, i processi di negoziazione, le abitudini e soprattutto i discorsi dei cinefili al cospetto di tracce di cinema sui social network e in particolare su Facebook. Inoltreprovo a dimostrare che la cinefilia è un'esperienza costitutivamente autobiografica, cui il web permette il perpetuare potenzialmente infinito della (auto)narrazione di sé.

Il trattato ‘Practica musice’ di Franchino Gaffurio (1496). Genesi, tradizione del testo, trascrizione interpretativa e traduzione.

La ricerca consiste nell’edizione e traduzione del trattato ‘Practica musice’ di Franchino Gaffurio corredata da apparati critici e storico-contestuali. Si inizia con la biografia dell’autore redatta secondo gli ultimi dati disponibili e si presenta una esposizione del contenuto del trattato con proposte di chiarimenti dei passi più oscuri. Segue quindi uno studio dei cambiamenti intercorsi tra le parti del trattato come trasmesse nei manoscritti preparatori e la sua versione finale a stampa, seguito da una indagine sulle edizioni successive all’editio princeps, con tabelle sulle varianti tra le edizioni. Vengono quindi offerte la trascrizione interpretativa del testo latino del trattato (che può essere considerata la più corretta attualmente disponibile ed è l’unica a riportare numeri di partizione testuale) seguita dalla sua traduzione in italiano, con trascrizione degli esempi musicali. Il trattato, diviso in quattro libri, ha per argomenti rispettivamente il cantus planus e le scale modali gregoriane, la musica misurata e le figure della notazione, l’arte del contrappunto e la più ampia casistica disponibile sulle proporzioni ritmiche.

La sociologia relazionale di Georg Simmel. La relazione come forma sociale vitale

La tesi di dottorato ha come oggetto il pensiero sociologico di Georg Simmel con particolare riferimento alla sua interpretazione nei diversi indirizzi di ricerca della sociologia relazionale contemporanea. In particolare, si propone una rilettura del contributo simmeliano alla luce del paradigma relazionale della sociologia di Pierpaolo Donati. Il lavoro di ricerca è stato condotto secondo una rigorosa ricognizione testuale dell’opus simmeliano e della bibliografia critica internazionale sull'argomento in oggetto. A partire dalla nozione di relazione sociale, si dipana l’analisi della proposta sociologica simmeliana: il termine tedesco Wechselwirkung (azione reciproca) racchiude la complessa semantica con cui assume senso l’intera teoria sociologica simmeliana. Simmel è il primo "sociologo relazionale", come sostenuto da Donati, e in questa ricerca si cerca di mostrare le evidenze della validità di tale asserzione. Nella formulazione simmeliana si trovano importanti indizi teorici che permettono di rielaborare la relazione nei termini di una “forma sociale vitale”. Questo significa che la relazione sociale trova la sua ragion d’essere in quanto fenomeno umano che si determina a partire dalle nozioni di “spirito” (Geist) e “vita”(Leben). Nel primo capitolo si chiarisce la natura di questa relazione sociale in rapporto alle varie proposte sociologiche relazionali in campo internazionale. Nel secondo capitolo si analizza in maniera critica la (ri)formulazione simmeliana della relazione come scambio (nella forma simbolica del denaro) e le interpretazioni relazionali che si sono succedute a partire da questo cambio di rotta. Nel terzo capitolo vengono passate in rassegna le principali figure relazionali (la vita della metropoli, la moda, il conflitto, il povero, lo straniero) con le quali si confronta il sociologo berlinese. Nel quarto capitolo si propone di rileggere fenomeni sociali e culturali come forme relazionali in riferimento alla sfera dell’arte e della teologia (religione).

La scrittura dell'interpretazione: Teoria e pratica della trascrizione musicale durante gli ‘anni veneziani’ di Bruno Maderna (1946-1952)

La definizione di «scrittura dell’interpretazione» comprime in una sola locuzione la descrizione dell’oggetto principale del nostro studio, ovvero il problema della trascrizione musicale, descritta, non tanto come un determinato genere musicale, quanto come una ragione di osmosi e interferenze tra il fatto compositivo e quello interpretativo. Ad una traversata di quel territorio ci si appresta incentrando la trattazione intorno alla figura e all’opera del giovane compositore e direttore Bruno Maderna, autore di diverse trascrizioni della cosiddetta musica antica (dall’Odhecaton A, Monteverdi, Viadana, Frescobaldi, Legrenzi, ed altri ancora). Attraverso gli esempi presentati si intende mostrare come l’approccio maderniano alla trascrizione musicale si giustifichi a partire dalla sua stessa teoria e pratica dell’interpretazione musicale, più che in base a concetti forti definiti sul versante della scrittura, quali ad esempio quelli di analisi e parodia. Pari attenzione si offre al contesto storico degli anni in cui egli gravita, opera e si afferma come musicista (1946-1952 circa), dedicando ampio spazio alle figure di Gian Francesco Malipiero, Angelo Ephrikian e Luigi Nono, autori a loro volta di trascrizioni e revisioni di opere del Cinquecento, del Seicento e del Settecento. Intorno ai loro rapporti viene fornita una documentazione significativa, in buona parte inedita o poco conosciuta dagli studiosi, resa disponibile grazie alle ricerche d’archivio di cui si avvantaggia la nostra trattazione.

La promozione dell'inclusione nei sistemi scolastici attraverso l'intervento di cooperazione internazionale: l'esperienza di El Salvador

La ricerca si colloca all’interno di un complesso intervento di cooperazione internazionale realizzato in El Salvador tra il 2009 e il 2014. Il Progetto di cooperazione è stato promosso dal Dipartimento di Scienze dell’Educazione dell’Università di Bologna e finanziato dalla Cooperazione Italiana. L’esperienza studiata rappresenta un esempio di promozione dell’inclusione nei sistemi scolastici di Paesi del Sud del mondo e si propone due obiettivi: 1) analizzare il processo di cambiamento della prospettiva di intervento promossa dalla cooperazione internazionale, evidenziando la dimensione educativa che sostiene processi di empowerment e ownership delle istituzioni locali; 2) contribuire al dibattito sull’ “inclusive education”, sostenendo processi di inclusione scolastica e sociale rivolti a tutti coloro che si trovano in situazione di svantaggio psico-fisico e/o socio-culturale. Le politiche locali del Ministero dell’Educazione dal 2009 hanno promosso un modello educativo con l’obiettivo di garantire il diritto all’educazione per tutti nella scuola pubblica. Lo studio costituisce un'indagine di tipo valutativo sul processo di sviluppo della scuola inclusiva in El Salvador, supportato dall’intervento di cooperazione internazionale. La ricerca utilizza in modo integrato strumenti di natura quantitativa (questionari) e qualitativa (interviste). Dai dati raccolti emerge come il processo di cooperazione sia stato caratterizzato dal principio della pari dignità tra esperti internazionali e autorità politiche e tecniche locali. Inoltre, la ricerca ha consentito di verificare come la cultura dell'inclusione si sia radicata in modo diffuso nella percezione della missione della scuola e il suo ruolo tra i protagonisti del sistema scolastico. Alla luce dei risultati, appare fondamentale continuare a investire sulla formazione tecnica delle figure chiave del sistema educativo; facilitare il processo di inclusione dei disabili nelle scuole regolari con una parallela trasformazione delle scuole speciali in centri di supporto all’integrazione; promuovere una sinergia di azione formativa tra il ministero, mondo accademico e della formazione professionale.

"Making Sense of Figures": Statistics, Computing and Information Technologies in Agriculture and Biology in Britain, 1920s-1960s

Throughout the twentieth century statistical methods have increasingly become part of experimental research. In particular, statistics has made quantification processes meaningful in the soft sciences, which had traditionally relied on activities such as collecting and describing diversity rather than timing variation. The thesis explores this change in relation to agriculture and biology, focusing on analysis of variance and experimental design, the statistical methods developed by the mathematician and geneticist Ronald Aylmer Fisher during the 1920s. The role that Fisher’s methods acquired as tools of scientific research, side by side with the laboratory equipment and the field practices adopted by research workers, is here investigated bottom-up, beginning with the computing instruments and the information technologies that were the tools of the trade for statisticians. Four case studies show under several perspectives the interaction of statistics, computing and information technologies, giving on the one hand an overview of the main tools – mechanical calculators, statistical tables, punched and index cards, standardised forms, digital computers – adopted in the period, and on the other pointing out how these tools complemented each other and were instrumental for the development and dissemination of analysis of variance and experimental design. The period considered is the half-century from the early 1920s to the late 1960s, the institutions investigated are Rothamsted Experimental Station and the Galton Laboratory, and the statisticians examined are Ronald Fisher and Frank Yates.

Institutional Processes and Discursive Strategies: Rhetoric and Vocabulary Analysis of CSR and Sustainability

The candidate tackled an important issue in contemporary management: the role of CSR and Sustainability. The research proposal focused on a longitudinal and inductive research, directed to specify the evolution of CSR and contribute to the new institutional theory, in particular institutional work framework, and to the relation between institutions and discourse analysis. The documental analysis covers all the evolution of CSR, focusing also on a number of important networks and associations. Some of the methodologies employed in the thesis have been employed as a consequence of data analysis, in a truly inductive research process. The thesis is composed by two section. The first section mainly describes the research process and the analyses results. The candidates employed several research methods: a longitudinal content analysis of documents, a vocabulary research with statistical metrics as cluster analysis and factor analysis, a rhetorical analysis of justifications. The second section puts in relation the analysis results with theoretical frameworks and contributions. The candidate confronted with several frameworks: Actor-Network-Theory, Institutional work and Boundary Work, Institutional Logic. Chapters are focused on different issues: a historical reconstruction of CSR; a reflection about symbolic adoption of recurrent labels; two case studies of Italian networks, in order to confront institutional and boundary works; a theoretical model of institutional change based on contradiction and institutional complexity; the application of the model to CSR and Sustainability, proposing Sustainability as a possible institutional logic.
