Raccontatori di storie: testo e voce nei cantari

Si richiamano i tratti della letteratura canterina come genere di testi in origine destinati all'esecuzione nelle piazze, e connotati a livello retorico da vari residui, indicatori e marche di oralit\ue0, che pi\uf9 tardi divengono simulazione di locuzione che si vuole comunque in \u201cpresa diretta" col pubblico. I cantari ci presentano un racconto profondamente caratterizzato dalla forza emotiva e perlocutoria della voce, a cui guardiamo con nostalgia in un'epoca in cui la letteratura e la testualit\ue0 divengono solitamente sempre pi\uf9 smaterializzate, e le parole rischiano di divaricarsi sempre pi\uf9 dalle cose

In margine all'ottava canterina, ai poemi in ottave del Boccaccio e alla comunicazione letteraria

Si riflette sulla popolarit\ue0 dei cantari nella loro pratica di mediazione di testi letterari, linguaggi e livelli di cultura. Funzione vitale dei cantari \ue8 proprio di garantire una continua osmosi di materiali e fonti che vengono messi in circolo e divengono terreno di mediazione culturale. Alcune delle caratteristiche dell\u2019ottava canterina possono inoltre meglio risaltare al confronto con i poemi in ottava rima di Boccaccio, strettamente vincolati a un preciso progetto autoriale.The essay reflects on the popularity of the \u201ccantari\u201d, mediators of literary texts, languages and levels of culture. The function of these texts is to promote an interactive process in which different materials and sources circulate and become a common heritage. Some caracteristics of the \u201cottava canterina\u201d can be confronted with Boccaccio\u2019s poems in ottava rima, on the contrary strictly conditioned by an authorial project

L'introduzione e la conclusione della VI giornata del «Decameron» e la loro valenza metanarrativa

Nella \u201ccornice\u201d della VI giornata, con valenza metanarrativa, risale in superficie un importante modello strutturale del \uabDecameron\ubb, quello della questione retorica e cortese, delle controversie come impianto organizzativo e tematico del ragionare dei componenti della brigata. Da questo luogo centrale emerge lo stretto legame tra le parti dell\u2019opera e la continuit\ue0 lessicale nel concepire e definire l\u2019universo poetico del narrabile (\uabragionamenti\ubb).In the \u201ccornice\u201d of the Sixth day of the \uabDecameron\ubb, with the Introduction and the Conclusion, can be detected a clear metapoetic intent. An important structural model for the ragionare of the brigata, the questione retorica and cortese and the controversie come back up to the surface. From this central section of the work we can see the accurate structural construction of the masterpiece and the lexical congruity of Boccaccio when he conceives and states the poetic universe of \u201cnarrabile\u201d (\uabragionamenti\ubb)

A proposito dell'invocazione a Venere, al sonno e al libro nella Fiammetta

Il contributo si sofferma sui moduli espressivi topici in Boccaccio fin dalla giovanile \uabElegia di Costanza\ubb dell'invocazione e dell'allocuzione, e indica inoltre una nuova fonte per l'allocuzione al libro che conclude l'opera nell'epistola VII delle \uabEroidi\ubb ovidiane \uabDido Aeneae\ubb

A proposito delle radici culturali dell'Europa

Il saggio riflette sul tema delle radici culturali dell\u2019Europa dal punto di vista della filologia romanza e dell\u2019unitariet\ue0 della cultura europea, a partire dall\u2019opera ormai classica di Curtius Letteratura europea e Medio Evo latino, di cui si sottolinea l\u2019attualit\ue0, fino a contributi pi\ufa recenti nel campo della romanistica.The essay deals with the topic of Europe\u2019s cultural tradition, underlining the value and up-to-dateness of Curtius\u2019 classical summa Europ\ue4ische Literatur und lateinisches Mittelalter, and reflects upon some examples of the unity of European culture and some recent critical contributions

Lunar lander and return propulsion system trade study

This trade study was initiated at NASA/JSC in May 1992 to develop and evaluate main propulsion system alternatives to the reference First Lunar Outpost (FLO) lander and return-stage transportation system concept. Thirteen alternative configurations were developed to explore the impacts of various combinations of return stage propellants, using either pressure or pump-fed propulsion systems and various staging options. Besides two-stage vehicle concepts, the merits of single-stage and stage-and-a-half options were also assessed in combination with high-performance liquid oxygen and liquid hydrogen propellants. Configurations using an integrated modular cryogenic engine were developed to assess potential improvements in packaging efficiency, mass performance, and system reliability compared to non-modular cryogenic designs. The selection process to evaluate the various designs was the analytic hierarchy process. The trade study showed that a pressure-fed MMH/N2O4 return stage and RL10-based lander stage is the best option for a 1999 launch. While results of this study are tailored to FLO needs, the design date, criteria, and selection methodology are applicable to the design of other crewed lunar landing and return vehicles

Search for low-mass WIMPs in a 0.6 kg day exposure of the DAMIC experiment at SNOLAB

We present results of a dark matter search performed with a 0.6 kg day exposure of the DAMIC experiment at the SNOLAB underground laboratory. We measure the energy spectrum of ionization events in the bulk silicon of charge-coupled devices down to a signal of 60 eV electron equivalent. The data are consistent with radiogenic backgrounds, and constraints on the spin-independent WIMP-nucleon elastic-scattering cross section are accordingly placed. A region of parameter space relevant to the potential signal from the CDMS-II Si experiment is excluded using the same target for the first time. This result obtained with a limited exposure demonstrates the potential to explore the low-mass WIMP region (<10 GeV/$c^{2}$) of the upcoming DAMIC100, a 100 g detector currently being installed in SNOLAB.Comment: 11 pages, 11 figure

Single Top Quark Production as a Probe for Anomalous Moments at Hadron Colliders

Single production of top quarks at hadron colliders via $gW$ fusion is examined as a probe of possible anomalous chromomagnetic and/or chromoelectric moment type couplings between the top and gluons. We find that this channel is far less sensitive to the existence of anomalous couplings of this kind than is the usual production of top pairs by $gg$ or $q\bar q$ fusion. This result is found to hold at both the Tevatron as well as the LHC although somewhat greater sensitivity for anomalous couplings in this channel is found at the higher energy machine.Comment: New discussion and 10 new figures added. uuencoded postscript fil
