Il ruolo del teatro di Sa’d Allah Wannus nel panorama del mondo arabo contemporaneo

Ercolanelli, Luisamaria <1980> 02 July 2008 (has links)
INTRODUZIONE. Presentazione della ricerca e del metedo seguito per realizzarla. CAPITOLO PRIMO. Il contesto storico, politico e sociale di riferimento. - Storia della Siria, - La Siria politica e il conflitto israelo-palestinese - La società siriana: multiculturalismo, tradizione, islam. - Teatro e letteratura in Siria, e nel Bilad AlSham. CAPITOLO SECONDO. I testi. Traduzione integrale di due opere teatrali di Sa’d Allah Wannus. Breve presentazione. - “ Riti di segni e trasformazioni.”, (tukus al-isharat wa-l-tahawwulat), 1994. Il dramma si svolge nella Damasco del XIX secolo, dove un affare di morale e buon costume è il punto di partenza per la metamorfosi dei suoi protagonisti, mettendo a nudo le riflessioni, i desideri più intimi, le contraddizioni e le angosce di una società in crisi. Interessante l’analisi delle figure femminili di questa piece, le loro scelte, il loro ruolo nella società e soprattutto la presa di coscienza delle loro posizioni. - “ I giorni ubriachi.” , (Alayyam Almakhmura), 1997. Il ritratto di una famiglia siriana degli anni trenta. Due genitori, quattro figli, e un nipote che a distanza di anni decide di ripercorrere e raccontarci le loro storie.Una madre che vive tormentata dal suo spettro e che decide di abbandonare la propria famiglia e i propri figli per seguire un altro uomo. Un padre che tiene con violenza le redini delle proprie relazioni, e che rifiuta l’occidente in tutte le sue forme per restare aggrappato alle proprie tradizioni. Un figlio che sceglie l’ordine e la carriera militare, e che, incapace di risolvere il suo rapporto di dipendenza dalla madre, e di risolvere il conflitto tra la legge e un affetto quasi morboso, sceglie di suicidarsi. Un figlio che sceglie la via della perdizione, delle droghe, del furto e degli affari illegali, e che va incontro al successo e alla ricchezza... CAPITOLO TERZO. Biografia di Sa’d Allah Wannus, presentazione delle sue opere principali. Sa’d Allah Wannus (1941 – 1997) è sicuramente uno dei principali protagonisti nell’ambito del teatro arabo contemporaneo. Scrittore, critico, drammaturgo, riformatore, uomo impegnato politicamente, e infine essere umano nella lotta tra la vita e la morte (muore a 56 anni per tumore, dopo un lungo periodo di degenza). Mio intento è quello di analizzare l’opera di quest’autore, attraverso i suoi numerosi scritti e piece teatrali (purtroppo al giorno d’oggi ancora quasi interamente non tradotte dall’arabo), fino ad arrivare, attraverso queste, ad una lettura della società araba contemporanea, e al ruolo che il teatro assume al suo interno. Vita e opere di Sa’ad Allah Wannus. Nasce in Siria nel 1941 in un piccolo villaggio vicino alla città di Tartous, sulla costa mediterranea. Dopo aver terminato gli studi superiori, nel 1959, parte per Il Cairo (Egitto), per studiare giornalismo e letteratura. Rientra a Damasco nel 1964, lavorando al tempo stesso come funzionario al ministero della cultura e come redattore o giornalista in alcune riviste e quotidiani siriani. Nel 1966 parte per Parigi, dove studierà con Jean-Louis Barrault, e dove farà la conoscenza delle tendenze del teatro contemporaneo. Ha l’occasione di incontrare scrittori e critici importanti come Jean Genet e Bernard Dort, nonché di conoscere le teorie sul teatro di Brech e di Piscator, dai quali sarà chiaramente influenzato. In questi anni, e soprattutto in seguito agli avvenimenti del Maggio 1968, si sviluppa in modo determinante la sua coscienza politica, e sono questi gli anni in cui compone alcune tra le sue piece più importanti, come: Serata di gala per il 5 giugno (haflat samar min ajl khamsa huzayran) nel 1968, L’elefante, oh re del tempo! (al-fil, ya malik al-zaman!) 1969, Le avventure della testa del Mamelucco Jaber (Meghamarat ra’s al-mamluk Jabiir) 1970, Una serata con Abu-Khalil al- Qabbani (Sahra ma’a Abi Khalil Al-Qabbani) 1972, Il re è il re (al-malik uwa al-malik) 1977. Parallelamente porta avanti una intensa attività artistica e intellettuale. Soggiorna di nuovo in Francia e a Weimar, per portare a termine la sua formazione teatrale, fonda il Festival di teatro di Damasco, traduce e mette in scena numerosi spettacoli, scrive e pubblica numerosi articoli e una importante serie di studi sul teatro, intitolata: Manifesto per un nuovo teatro arabo (bayanat limasrah ‘arabi jadid) (1970). Scrive in numerose riviste e giornali e fonda la rivista La vita teatrale (al-hayyat al-masrahiyya), del quale sarà capo redattore. La visita del presidente egiziano Anouar Sadat a Gerusalemme nel 1977 e gli accordi di Camp David l’anno seguente, lo gettano in una profonda depressione. E’ l’inizio di un lungo periodo di silenzio e di smarrimento. Ritornerà a scrivere solamente nel 1989, con l’inizio della prima Intifada palestinese, scrive allora una piece teatrale intitolata Lo stupro (al-ightisab), dove presenta un’analisi della struttura dell’elite al potere in Israele. Questo testo apre una nuova epoca creativa, durante la quale Wannus compone alcuni testi molto importanti, nonostante la malattia e il cancro che gli viene diagnosticato nel 1992. Tra questi le pieces Miniature storiche (munamnamat tarakhiyya), nel 1993, e Rituali per una metamorfosi (tukus al-isharat wa-l-tahawwulat), nel 1994 e A proposito della memoria e della morte (‘an al-dhakira wa-l-mawt) nel 1996, una sua ultima opera in cui sono raccolti dei racconti, drammi brevi e una lunga meditazione sulla malattia e la morte. Nel 1997 l’UNESCO gli chiede di redigere il messaggio per la Giornata Mondiale del Teatro, che si tiene ogni anno il 27 marzo. Nel 1997, poche settimane prima della sua scomparsa, realizza insieme ad Omar Almiralay il film documentario Il y a tant de choses a reconter, una intervista in cui Wannus parla della sua opera, e del conflitto Israelo-Palestinese. Muore a 56 anni, il 15 maggio 1997, per un’amara coincidenza proprio il giorno anniversario della creazione di Israele. Wannus drammaturgo engagè: l’importanza del conflitto israelo palestinese nella sua opera. Un’analisi dell’influenza e dell’importanza che le opere di Wannus hanno avuto nel seno della società araba, e soprattutto il suo impegno costante nell’uso del teatro come mezzo per la presa di coscienza del pubblico dei problemi della società contemporanea. Punto cardine dell’opera di Wannus, il conflitto israelo palestinese, e il tentativo costante in alcune sue opere di analizzarne le cause, le strutture, le parti, i giochi di potere. E’ il simbolo di tutta la generazione di Wannus, e delle successive. Analisi delle illusioni e dei miti che la società araba ripropone e che Wannus ha cercato più volte di mettere a nudo. La lotta contro le ipocrisie dei governi, e il tentativo di far prendere coscienza alla società araba del suo ruolo, e delle conseguenze delle sue azioni. L’individuo, la famiglia, la società ... il teatro. Distruggere le apparenze per mettere a nudo l’essere umano nella sua fragilità. CONCLUSIONI. APPENDICE: Intervista con Marie Elias BIBLIOGRAFIA.

Meccanismi evolutivi dei parapoxvirus: caratterizzazione genomica di pseudocowpoxvirus e messa a punto di sistemi per lo studio delle ricombinazioni

Vaccari, Francesca <1977> 28 April 2009 (has links)
The Poxviruses are a family of double stranded DNA (dsDNA) viruses that cause disease in many species, both vertebrate and invertebrate. Their genomes range in size from 135 to 365 kbp and show conservation in both organization and content. In particular, the central genomic regions of the chordopoxvirus subfamily (those capable of infecting vertebrates) contain 88 genes which are present in all the virus species characterised to date and which mostly occur in the same order and orientation. In contrast, however, the terminal regions of the genomes frequently contain genes that are species or genera-specific and that are not essential for the growth of the virus in vitro but instead often encode factors with important roles in vivo including modulation of the host immune response to infection and determination of the host range of the virus. The Parapoxviruses (PPV), of which Orf virus is the prototypic species, represent a genus within the chordopoxvirus subfamily of Poxviridae and are characterised by their ability to infect ruminants and humans. The genus currently contains four recognised species of virus, bovine papular stomatitis virus (BPSV) and pseudocowpox virus (PCPV) both of which infect cattle, orf virus (OV) that infects sheep and goats, and parapoxvirus of red deer in New Zealand (PVNZ). The ORFV genome has been fully sequenced, as has that of BPSV, and is ~138 kb in length encoding ~132 genes. The vast majority of these genes allow the virus to replicate in the cytoplasm of the infected host cell and therefore encode proteins involved in replication, transcription and metabolism of nucleic acids. These genes are well conserved between all known genera of poxviruses. There is however another class of genes, located at either end of the linear dsDNA genome, that encode proteins which are non-essential for replication and generally dictate host range and virulence of the virus. The non-essential genes are often the most variable within and between species of virus and therefore are potentially useful for diagnostic purposes. Given their role in subverting the host-immune response to infection they are also targets for novel therapeutics. The function of only a relatively small number of these proteins has been elucidated and there are several genes whose function still remains obscure principally because there is little similarity between them and proteins of known function in current sequence databases. It is thought that by selectively removing some of the virulence genes, or at least neutralising the proteins in some way, current vaccines could be improved. The evolution of poxviruses has been proposed to be an adaptive process involving frequent events of gene gain and loss, such that the virus co-evolves with its specific host. Gene capture or horizontal gene transfer from the host to the virus is considered an important source of new viral genes including those likely to be involved in host range and those enabling the virus to interfere with the host immune response to infection. Given the low rate of nucleotide substitution, recombination can be seen as an essential evolutionary driving force although it is likely underestimated. Recombination in poxviruses is intimately linked to DNA replication with both viral and cellular proteins participate in this recombination-dependent replication. It has been shown, in other poxvirus genera, that recombination between isolates and perhaps even between species does occur, thereby providing another mechanism for the acquisition of new genes and for the rapid evolution of viruses. Such events may result in viruses that have a selective advantage over others, for example in re-infections (a characteristic of the PPV), or in viruses that are able to jump the species barrier and infect new hosts. Sequence data related to viral strains isolated from goats suggest that possible recombination events may have occurred between OV and PCPV (Ueda et al. 2003). The recombination events are frequent during poxvirus replication and comparative genomic analysis of several poxvirus species has revealed that recombinations occur frequently on the right terminal region. Intraspecific recombination can occur between strains of the same PPV species, but also interspecific recombination can happen depending on enough sequence similarity to enable recombination between distinct PPV species. The most important pre-requisite for a successful recombination is the coinfection of the individual host by different virus strains or species. Consequently, the following factors affecting the distribution of different viruses to shared target cells need to be considered: dose of inoculated virus, time interval between inoculation of the first and the second virus, distance between the marker mutations, genetic homology. At present there are no available data on the replication dynamics of PPV in permissive and non permissive hosts and reguarding co-infetions there are no information on the interference mechanisms occurring during the simultaneous replication of viruses of different species. This work has been carried out to set up permissive substrates allowing the replication of different PPV species, in particular keratinocytes monolayers and organotypic skin cultures. Furthermore a method to isolate and expand ovine skin stem cells was has been set up to indeep further aspects of viral cellular tropism during natural infection. The study produced important data to elucidate the replication dynamics of OV and PCPV virus in vitro as well as the mechanisms of interference that can arise during co-infection with different viral species. Moreover, the analysis carried on the genomic right terminal region of PCPV 1303/05 contributed to a better knowledge of the viral genes involved in host interaction and pathogenesis as well as to locate recombination breakpoints and genetic homologies between PPV species. Taken together these data filled several crucial gaps for the study of interspecific recombinations of PPVs which are thought to be important for a better understanding of the viral evolution and to improve the biosafety of antiviral therapy and PPV-based vectors.

In nome della comunità. Analisi dei testi della sicurezza e del terrorismo

Salerno, Daniele <1980> 29 May 2009 (has links)
The focus of this dissertation is the relationship between the necessity for protection and the construction of cultural identities. In particular, by cultural identities I mean the representation and construction of communities: national communities, religious communities or local communities. By protection I mean the need for individuals and groups to be reassured about dangers and risks. From an anthropological point of view, the relationship between the need for protection and the formation and construction of collective identities is driven by the defensive function of culture. This was recognized explicitly by Claude Lévi-Strauss and Jurij Lotman. To explore the “protective hypothesis,” it was especially useful to compare the immunitarian paradigm, proposed by Roberto Esposito, with a semiotic approach to the problem. According to Esposito, immunity traces borders, dividing Community from what should be kept outside: the enemies, dangers and chaos, and, in general, whatever is perceived to be a threat to collective and individual life. I recognized two dimensions in the concept of immunity. The first is the logic dimension: every element of a system makes sense because of the network of differential relations in which it is inscribed; the second dimension is the social praxis of division and definition of who. We are (or what is inside the border), and who They are (or what is, and must be kept, outside the border). I tested my hypothesis by analyzing two subject areas in particular: first, the security practices in London after 9/11 and 7/7; and, second, the Spiritual Guide of 9/11 suicide bombers. In both cases, one observes the construction of two entities: We and They. The difference between the two cases is their “model of the world”: in the London case, one finds the political paradigms of security as Sovereignty, Governamentality and Biopolitics. In the Spiritual Guide, one observes a religious model of the Community of God confronting the Community of Evil. From a semiotic point view, the problem is the origin of respective values, the origin of respective moral universes, and the construction of authority. In both cases, I found that emotional dynamics are crucial in the process of forming collective identities and in the process of motivating the involved subjects: specifically, the role of fear and terror is the primary factor, and represents the principal focus of my research.

Testo e memoria tra semiotica e scienze cognitive: una situazione sperimentale intorno al ricordo di un film

Odoardi, Paolo <1980> 11 May 2009 (has links)
The research project presented in this dissertation is about text and memory. The title of the work is "Text and memory between Semiotics and Cognitive Science: an experimental setting about remembering a movie". The object of the research is the relationship between texts or "textuality" - using a more general semiotic term - and memory. The goal is to analyze the link between those semiotic artifacts that a culture defines as autonomous meaningful objects - namely texts - and the cognitive performance of memory that allows to remember them. An active dialogue between Semiotics and Cognitive Science is the theoretical paradigm in which this research is set, the major intend is to establish a productive alignment between the "theory of text" developed in Semiotics and the "theory of memory" outlined in Cognitive Science. In particular the research is an attempt to study how human subjects remember and/or misremember a film, as a specific case study; in semiotics, films are “cinematographic texts”. The research is based on the production of a corpus of data gained through the qualitative method of interviewing. After an initial screening of a fulllength feature film each participant of the experiment has been interviewed twice, according to a pre-established set of questions. The first interview immediately after the screening: the subsequent, follow-up interview three months from screening. The purpose of this design is to elicit two types of recall from the participants. In order to conduce a comparative inquiry, three films have been used in the experimental setting. Each film has been watched by thirteen subjects, that have been interviewed twice. The corpus of data is then made by seventy-eight interviews. The present dissertation displays the results of the investigation of these interviews. It is divided into six main parts. Chapter one presents a theoretical framework about the two main issues: memory and text. The issue of the memory is introduced through many recherches drown up in the field of Cognitive Science and Neuroscience. It is developed, at the same time, a possible relationship with a semiotic approach. The theoretical debate about textuality, characterizing the field of Semiotics, is examined in the same chapter. Chapter two deals with methodology, showing the process of definition of the whole method used for production of the corpus of data. The interview is explored in detail: how it is born, what are the expected results, what are the main underlying hypothesis. In Chapter three the investigation of the answers given by the spectators starts. It is examined the phenomenon of the outstanding details of the process of remembering, trying to define them in a semiotic way. Moreover there is an investigation of the most remembered scenes in the movie. Chapter four considers how the spectators deal with the whole narrative. At the same time it is examined what they think about the global meaning of the film. Chapter five is about affects. It tries to define the role of emotions in the process of comprehension and remembering. Chapter six presents a study of how the spectators account for a single scene of the movie. The complete work offers a broad perspective about the semiotic issue of textuality, using both a semiotic competence and a cognitive one. At the same time it presents a new outlook on the issue of memory, opening several direction of research.
