Realtà, realismo, straniamento : Auerbach e il romanzo cavalleresco fino a Cervantes
No full textAuerbach’s research, besides exploring the three main fields the author explicitly names (i.e. the succession of different and differently grounded forms of realism in literary fiction, the alternate splitting and melting of styles, the link between literary work and a Christian vision of the world), in various chapters of Mimesis, and particularly in chs. 2, 6, 12, 14 and 20, is also focused, albeit only implicitly, on the developments of a further distinctive feature in Western literature, which is the emergence of subjectivity in the representation of reality. Focusing mainly on the chapter on courtly romance (ch. 6) and on the Quijote (ch. 14), this essay will examine Auerbach’s interpreting work on texts that adopt, in different ways, a ‘subjective point of view’; this kind of interpretation is, in part, unexpectedly similar to the approach of other critics and theorists of literature contemporary to Auerbach, like Bachtin, Américo Castro and Viktor Šklovskij
Shedding light on the black hole: The roll-out of broadband access networks by private operators
No full textSeveral market studies have indicated that the roll-out of broadband has significant economic and social relevance. The investments in broadband infrastructures needed to realise these economic and social benefits are, however, high-risk. This is firstly caused by the fact that the roll-out of access networks is extremely costly and requires high initial investments. Moreover, the multidisciplinary environment and involvement of many actors with diverging objectives and interests cause high complexity. Moreover, the market for broadband is changing fast and continuously. Although broadband has been on the academic research agenda for quite some time, this has as yet not resulted in a structured insight into the decision-making process around the upgrading of broadband networks, seen from the perspective of private operators and taking into account the vast complexity of the surroundings in which this decision-making process takes place in. The objective of this research was to provide a unifying theory combining technical, economic, market-related and regulatory factors with regard to an evolutionary, flexible approach of network upgrading from a decision-maker perspective. The result of this research is a robust, explanatory, parsimonious model for the impact and outcomes of broadband roll-out. This model provides a certain degree of stability in this multidisciplinary, unpredictable and highly dynamic research field.Technology, Policy and Managemen
“Maistre (certa)”. Niveaux de savoir et conception du monde chez Guillaume IX d’Aquitaine
No full textStarting with a study by M. Black (Models and Archetypes, 1958), the author examines the possibility of broadening this heuristic perspective to include literature. In particular, she analyses a text by William IX, in which the troubadour seems identify himself with God
Oltre lo specchio: il Joufroi de Poitiers e la cultura lirica del suo autore
No full textCome è stato a più riprese osservato, il Joufroi de Poitiers, romanzo d’autore borgognone collocabile verso la metà del XIII secolo, si ispira molto da vicino alla figura di Guglielmo IX d’Aquitania, grande signore e primo trovatore di cui ci siano giunti i componimenti. Ma a quali materiali si ispira veramente l’autore del Joufroi? Alla vida provenzale conservata, o piuttosto a una più ampia biografia latina perduta, o ad altri testi ancora? La presente ricerca cercherà di mettere in luce quali siano state le effettive fonti del romanzo e di abbozzare un’ipotesi che spieghi le motivazioni di questi recuperi.As has been repeatedly noted, Joufroi de Poitiers, a novel written by a Burgundian author and composed around the middle of the thirteenth century, is based very closely on the figure of William IX of Aquitaine, great lord and first troubadour whose poems have been compiled. But what materials did truly inspire the author of Joufroi? The extant Provençal vida, or rather a lost broader Latin biography, or still other texts? This research will try to shed light on what were the actual sources of the novel and to outline a hypothesis that explains the motivations of these works

Separating Convective from Diffusive Mass Transport Mechanisms in Ionic Liquids by Redox Pro-fluorescence Microscopy
No full textThe study of electrochemical reactivity requires analytical techniques capable of probing the diffusion of reactants and products to and from electrified interfaces. Information on diffusion coefficients is often obtained indirectly by modeling current transients and cyclic voltammetry data, but such measurements lack spatial resolution and are accurate only if mass transport by convection is negligible. Detecting and accounting for adventitious convection in viscous and wet solvents, such as ionic liquids, is technically challenging. We have developed a direct, spatiotemporally resolved optical tracking of diffusion fronts which can detect and resolve convective disturbances to linear diffusion. By tracking the movement of an electrode-generated fluorophore, we demonstrate that parasitic gas evolving reactions lead to 10-fold overestimates of macroscopic diffusion coefficients. A hypothesis is put forward linking large barriers to inner-sphere redox reactions, such as hydrogen gas evolution, to the formation of cation-rich overscreening and crowding double layer structures in imidazolium-based ionic liquids
Determination of the molecular and physiological basis of citric acid tolerance in spoilage yeast
No full textThe ability of yeasts to grow and adapt under extreme environmental conditions including within the presence of weak organic acid preservatives has led to substantial economic losses through manufactured food and beverage spoilage. The food industry has employed the use of various weak organic acids such as sorbic, benzoic and acetic acid as preservatives to help prevent spoilage by yeasts and moulds. The mechanisms by which S. cerevisiae is able to adapt to these weak organic acids have been extensively studied. A lesser studied weak organic acid preservative is citric acid. The aim of this study was to gain further information on the mechanisms of citric acid adaptation and through this identify potential targets for new preservation strategies.
Current knowledge indicates the involvement of the HOG pathway in citric acid adaptation. A citric acid sensitivity screen from a previous study also isolated a SR protein kinase Sky1p, involved in polyamine metabolism, which has been connected with other crucial cellular processes including modulation of ion homeostasis and osmotic shock.
In this study we have undertaken a systematic screen for genes that confer increased sensitivity to citric acid paying particular attention to those involved in polyamine metabolism and those known to encode proteins which have evidence of interactions with Sky1p. Many of the deletion strains tested exhibited hypersensitivity to citric acid including Δsky1. Protein-protein interaction maps for Sky1p highlighted an interesting secondary interacting protein Nmd5p, an importin crucial for the nuclear localization of Hog1p. This information suggested there may be the possibility of linkage between Sky1p and Hog1p and their roles in citric acid tolerance, perhaps through Nmd5p. This provided an incentive to perform a range of experiments to test this theory.
Proteomic and phosphoproteomic analyses were carried out to study protein expression and phosphorylation changes in response to citric acid stress. Comparative proteomic analyses for Δsky1, Δhog1 and BY4741a with and without citric acid identified four instances of analogous protein expression responses in both Δsky1 and Δhog1, suggesting functional overlap upon exposure to citric acid.
Epistasis studies of Δhog1Δsky1 suggested that the two protein kinases do not function on the same pathway. However, overexpression analyses did suggest some functional interaction between Hog1p and Sky1p in mediating citric acid resistance since overexpression of Sky1p in Δhog1 resulted in partial rescue of growth. Further supporting evidence for some functional interaction or linkage was provided by Hog1p phosphorylation and localisation studies. Δsky1 exhibited dual phosphorylation of Hog1p in the absence of citric acid stress; implying that loss of SKY1 results in dual phosphorylation of Hog1p by either prompting phosphorylation or perhaps by interfering with dephosphorylation of Hog1p. Localisation studies of Hog1p proved that like osmotic stress, citric acid stress results in nuclear translocation of Hog1p and deletion of SKY1 seemed to interfere with this localisation to some extent.
In light of the results attained in this study we believe we have evidence to propose a novel role for Sky1p in mediating resistance to citric acid and that there is also substantial evidence to suggest that Sky1p shares some functional redundancy and perhaps functional linkage with Hog1p in citric acid adaptation

La guerra interdetta : "Il campo 29" di Sergio Antonielli
No full textIl campo 29 is the debut as novelist of Sergio Antonielli. It was
published in Milan in 1949 by “Edizioni Europee” and in 1976
by “Editori Riuniti”. The novel tells the personal experience of
imprisonment in British Raj during the Second World War with other
ten thousand Italian officers.
Through the analysis of the text and documents from the archives
of the author, stored in the Centro Apice, I would like to discuss the
techniques of composition that make this work a peculiar case in the
post-world war literary system. Antonielli, forcing himself to overcome
the tragedy suffered, commits to the writing a dual purpose: to avoid
mere “documentarismo” without overindulging in the romance, and
to take the advantage of the exceptional nature of his experience to
create a work that exceed all individual and historical contingencies.
In respect of these moral and stylistic imperatives, the writer refuses
the autobiography and choices a choral intonation, different from
sentimental style, typical of other writers involved in the literature
of war. His critic studies and the introductions, written by author for
two editions, show distinct interpretations about his work and about
typical methods and category of neorealist literature: document,
diary, autobiographical novel.
The story does not give way to political disquisitions or to sentimental
parenthesis, but it consists of representation of the life in prison
camps. A “city of prisoners” comes alive, where coexist vices and
virtues of the normal society, and where the war is banned
