L'Introduzione ricostruisce la storia dell'Archivio fino all'acquisizione nel 1997 da parte dell'Archivio del Novecento della Sapienza, la sua composizione e consistenza, gli interventi di ordinamento parziale fatti dalla scrittrice, con criteri volti a proiettare un'immagine di sé e a valorizzare il proprio lavoro e il ruolo ricoperto nella società letteraria; ricostruisce sinteticamente il percorso creativo della scrittrice nel contesto della cultura contemporanea e la fortuna critica dei testi
Fermi level pinning and interface states at Pb-Si(111) interface
No full textThe first theoretical analysis of the electronic properties of the Pb-Si(111) interface at monolayer coverage is presented. We have used the self-consistent linear muffin-tin orbital method with the atomic-sphere-approximation in a supercell geometry. The results show the presence of a discrete true interface state which is responsible of the pinning of the Fermi level and of the large Schottky barrier heights found for this system

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
ELECTRONIC-STRUCTURE OF THIN SI LAYERS IN CAF2 - HYBRIDIZATION VERSUS CONFINEMENT
No full textWe present first principle calculations of thin (1-7 double layers) silicon (111) layers in CaF2, a system with strong analogies to porous silicon. We show that the Si band gap opening is dominated by the valence band which follows the effective mass confinement picture, while the conduction band is found to flatten and shift very modestly due to hybridization effects between Si and Ca states which lead to bonding-antibonding interface states in the gap. The relevance of these results for Si-based low dimensional structures is discussed
