Paul Dawson. Il ritorno dell’onniscienza nella narrativa contemporanea
No full textSi traduce qui “The Return of Omniscience in Contemporary Fiction”, saggio di Paul Dawson pubblicato nel 2009 sul secondo numero – volume diciassettesimo – di Narrative. Il saggio tratta del ritorno del narratore onnisciente nella narrativa in lingua inglese degli ultimi vent’anni. L’ipotesi messa in gioco da Dawson è che questo ritorno si debba anzitutto a ragioni di tipo sociale, in particolare alla volontà da parte di molti scrittori di rivendicare il loro ruolo di intellettuali pubblici. I narratori onniscienti che compaiono oggi in molti romanzi e racconti sarebbero delle specie di controfigure dei rispettivi autori reali, e dall’interno dei singoli testi contribuirebbero ad amplificarne voce e opinioni. Dopo una prima parte in cui è ripercorso per sommi capi il dibattito intorno all’onniscienza avvenuto verso la metà dei primi anni Duemila, il saggio si sofferma sullo specifico dell’onniscienza contemporanea, per poi passare a descrivere le principali tipologie di narratore onnisciente riscontrabili nei romanzi e racconti pubblicati negli ultimi anni.
La traduzione è preceduta da una breve introduzione in cui sono presentate le principali questioni affrontate nel saggio, e insieme ne vengono messi in luce gli aspetti suscettibili di propiziare future indagini.
This is the Italian translation of the article “The Return of Omniscience in Contemporary Fiction” by Paul Dawson (Narrative, 2, 17, 2009), about the return of the omniscient narrator in British and American literary fiction of the last twenty years. Dawson’s hypothesis is that this return is first of all due to social reasons, in particular to the will of many writers to reclaim their role as public intellectuals. The omniscient narrators who appear today in many novels and short stories could be viewed as a sort of stuns of their respective real authors, whose and opinions they would textually amplify. After a first part briefly dedicated to the most recent debates about omniscience, the essay focuses on the specificity of contemporary omniscience, finally analysing the main typologies of omniscient narrator in novels and short stories published along the last years.
This translation is preceded by a brief introduction presenting the main issues of the essay and bringing to light its most promising aspects for the future investigations.
Honey Bee Antiviral Immune Barriers as Affected by Multiple Stress Factors: A Novel Paradigm to Interpret Colony Health Decline and Collapse
Full text linkAny attempt to outline a logical framework in which to interpret the honey bee health decline and its contribution to elevated colony losses should recognize the importance of the multifactorial nature of the responsible syndrome and provide a functional model as a basis for defining and testing working hypotheses. We propose that covert infections by deformed wing virus (DWV) represent a sword of Damocles permanently threatening the survival of honey bee colonies and suggest that any factor affecting the honey bee’s antiviral defenses can turn this pathogen into a killer. Here we discuss the available experimental evidence in the framework of a model based on honey bee immune competence as affected by multiple stress factors that is proposed as a conceptual tool for analyzing bee mortality and its underlying mechanisms
Host regulation by the aphid parasitoid Aphidius ervi: the role of teratocytes.
No full textThe biochemical profile and metabolism of Acyrthosiphon pisum (Harris) (Homoptera, Aphididae) are markedly altered and redirected in response to parasitization by the endophagous braconid Aphidius ervi Haliday (Hymenoptera,
Braconidae). In the present study, the role played in the host regulation process by teratocytes, cells deriving from the dissociation of the embryonic membrane of the parasitoid, is taken into consideration. The protein synthesis activity of these cells of embryonic origin is analysed in vitro and an essential characterization of those proteins de novo synthesized and released in the incubation medium is provided. Teratocytes, obtained by
dissecting parasitized host aphids, 3, 4 and 5 days after parasitoid oviposition, were incubated in vitro and, at the
end of the incubation period, were separated from the medium for SDS-PAGE analysis of both cellular and secreted
proteins. Various cellular proteins were more abundant as the time between parasitization and teratocyte collection
increased. Furthermore, two proteins, showing an approximate molecular mass of 15 kD (p15) and 45 kD (p45) respectively, were abundantly secreted in the incubation medium by 5 day-old teratocytes. Incubations in presence of 35S radiolabelled amino acids indicated that p15 and p45 are both synthesized by A. ervi teratocytes. The aminoacid composition of these two proteins was similar to that reported for other insect proteins with a demonstrated nutritional function. The p45 protein was found to be glycosylated. A tentative physiological model describing the host regulation role played by different parasitoid-derived factors is proposed
