Esistenza e omicidio nella cosmogonia norrena
No full textThe present article traces the main steps of the origin of the world according to the Norse cosmogony, bur from an intercultural perspective: thus the various moments in which existence takes shape are in close dialogue with other cultures – also very distant as the Indian or Greek one – and in a relationship of interdependence with the Norse and Germanic concept of murder, which justifies its final outcome

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
Computational studies of the structure, dynamics and native content of amyloid-like fibrils of ribonuclease A
No full textThe characterization at atomic resolution of amyloid-like protein aggregates is one of the fundamental problems of modern biology. In particular, the question whether native-like domains are retained or completely refolded in the amyloid state and the identification of possible mechanisms for macromolecular ordered aggregation represent major unresolved puzzles. To address these issues, in this article we examine the stability, dynamics, and conservation of native-like properties of several models of a previously designed amyloid-like fibril of RNase A (Sambashivan et al., Nature 2005; 437:266-269). Through the use of molecular dynamics (MD) simulations, we have provided molecular-level insights into the role of different parts of the sequence on the stability of fibrils, the collective properties of supramolecular complexes, and the presence of native-like conformations and dynamics in supramolecular aggregates. We have been able to show that within the fibrils the three-dimensional globular domain-swapped units preserve the conformational dynamical and hydration properties typical of the monomeric state, providing a rationalization for the experimentally observed catalytic activity of fibrils. The nativeness of the globular domains is not affected by the amyloidogenic stretches, which determine the molecular recognition process underlying aggregation through the formation of a stable steric zipper motif. Moreover, through the study of the hydration features of a single sheet model, we have been able to show that polyglutamine stretches of the domain-swapped ribonuclease tend to minimize the interaction with water in favor of sidechain-sidechain interactions, shedding light on the factors leading to the supramolecular assembly of β-sheet layers into dry steric zippers. © 2007 Wiley-Liss, Inc
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
