No full textThirty years on from publication of her first book, and
amidst epoch-making changes to the university system, especially in Italy, the author reconstructs her own intellectual and professional
story. In this ego histoire Ilaria Porciani goes over the milestones and encounters of her working life, as well as some material and institutional career aspects of an Italian woman historian across the turn of the millennium

Early Greek Colonies and Greek Cultural Identity: Megara Hyblaia and the Phaeacians
No full textSome recent approaches to the relationship between ancient cultures in the context of the Mediterranean aim at recalibrating the notion of identity in the early stages of historical development. Archaic Greece is a case in point: a traditional view highlights the role of early Greek “colonization” (8th-7th centuries B.C.) in forging a sense of Greek identity, that would have been elicited by contacts/contrasts with the inhabitants of the places where the Greeks established their colonies. Today, new perspectives emphasize phenomena like hybridity (the emergence of new identities in colonial contexts) and peaceful interactions, so that Hellenic identity per se does not hold as a historical category any longer. This paper explores the possibility of refreshing this notion and of exploiting it in the study of archaeological evidence of the early phases of Greek town planning (Megara Hyblaia, Sicily).Les premières colonies grecques et l’identité culturelle grecque : Mégara Hyblaea et les Phéaciens.
De récentes études sur les relations entre les cultures anciennes dans le contexte méditerranéen tentent de réviser le rôle de la notion d’identité aux premiers stades du développement historique. La Grèce archaïque est un cas intéressant : dans une vision traditionnelle des choses, on souligne le rôle de la première « colonisation » grecque (VIIIe-VIIe siècles av. J.-C.) dans l’élaboration d’un sentiment d’identité grecque, qui serait né des contacts/contrastes avec les habitants des lieux où les Grecs établirent leurs colonies. À l’heure actuelle, de nouvelles perspectives mettent l’accent sur des phénomènes tels que l’hybridité (l’émergence de nouvelles identités dans des contextes coloniaux) et les interactions pacifiques, de sorte que l’identité hellénique per se ne puisse plus tenir en tant que catégorie historique. Cet article essaie de revisiter cette notion afin de l’exploiter pour l’étude des données archéologiques correspondant aux premières phases de l’urbanisation grecque (Mégara Hyblaea, Sicile).Porciani Leone.

No full textWhitening Optical Effect of New Chewing Gums
No full textBackground: Today, many treatments are available to enhance the color of teeth, but they require a few days to weeks to deliver this effect. Objective: To evaluate the instantaneous optical whitening effect of two new sugar-free chewing gums and one dentifrice of proven efficacy versus one placebo chewing gum. Methods: This was a single-blind, parallel trial. 424 participants entered the study and were randomly allocated to four groups. They received a personal silicone mask with a calibrated hole at one upper incisor to apply a dental colorimeter. The tools tested were chewing-gum containing indigotine (E132-FD&C Blue 2) and spirulina, chewing-gum containing only spirulina, chewing-gum placebo, and dentifrice containing Blue Covarine. Vita® Easyshade scored the tooth color, and the WIO and WID whiteness indexes were calculated. For chewing gums, the color of the teeth was scored before the assumption and after 2’30” of mastication. For dentifrice, participants brushed for 1’30”, then rinsed, and the color was scored before brushing and after 2’30”. Statistical analysis was performed by ANOVA and Tukey post-hoc. Results: The two experimental whitening chewing gums and the dentifrice significantly increased the WIO and the WID indexes from the baselines (p<0.001). Moreover, their effects were statistically greater than those reported for the placebo chewing gum (p<0.05) but not significatively different among them (p=NS). Conclusion: All the tested whitening tools showed an instant optical whitening perception. Further studies are required to assess the intensity of the effect over a prolonged time to meet the people's request for fast whitening tools
