Et s’il n’était pas mort à Prague ? de Marco Bacci : une réécriture de La Métamorphose de Franz Kafka
Full text linkAprès une première édition à tirage limité en 1991, l’éditeur italien Mondadori publia en 1996 un recueil de nouvelles de jeunes auteurs. Et s’il n’était pas mort à Prague ? de Marco Bacci est l’une d’entre elles. Il s’agit en fait d’une suite de La Métamorphose de Kafka : un balayeur recueille Gregor, trouvé parmi des détritus, et le soigne. Après une douloureuse métamorphose, celui-ci recouvre sa forme humaine et, sous les traits de Franz Kafka, tire vengeance de son père.Bien loin d’être une simple suite, ce texte propose une réécriture de la nouvelle à l’instar de certaines critiques des années 1990 : La forme animale n’est plus uniquement déshumanisante, au contraire, le nouveau Gregor sait en tirer l’énergie nécessaire à surmonter ses inhibitions. Dans la nouvelle italienne, la métamorphose fait office de psychanalyse et c’est un tout nouveau Gregor qui s’impose en lieu et place du personnage kafkaïen tandis qu’un nouveau texte se superpose au premier.Nach einer ersten limitierten Ausgabe 1991 veröffentlichte der italienische Verlag Mondadori 1996 eine Anthologie von Novellen junger Autoren. Die Novelle Wäre er doch nicht in Prag gestorben ? von Marco Bacci gehört dazu. In der Tat handelt es sich um eine Fortsetzung von Kafkas Verwandlung : Ein Straßenfeger nimmt Gregor, den er unter einem Haufen Abfälle gefunden hat, auf und pflegt ihn. Nach einer schmerzhaften Verwandlung erlangt Gregor seine menschliche Form zurück – nun sieht er wie Franz Kafka aus – und rächt sich an seinem Vater.Die Novelle kann aber keinesfalls als bloße Fortsetzung betrachtet werden, sondern eher als eine neue Interpretation, in der sich die Tierform wie in manchen Rezensionen der 1990er Jahre nicht auf eine entmenschlichende Dimension reduzieren läßt. Im Gegenteil versteht es Gregor, daraus die nötige Energie zu ziehen, um seine Hemmungen zu überwinden. In der italienischen Novelle fungiert die Verwandlung als Psychoanalyse. Anstelle der kafkaischen Figur steht ein ganz neuer Gregor, und gleichzeitig überdeckt der neue Text den Ersteren wie ein Palimpsest
Role of denaturation in Maltose Binding Protein translocation dynamics
No full textWe present a computational study on the driven transport of the Maltose Binding Protein (MBP) across nanochannels in the framework of coarse-grained modeling. The work is motivated by recent experiments on voltage-driven transport of MBP across nanopores exploring the influence of denaturation on translocation pathways. Our simplified approach allows a statistical mechanical interpretation of the process which may be convenient also to the experiments. Specifically, we identify and characterize short and long channel blockades, associated to the translocation of denaturated and folded MBP conformations, respectively. We show that long blockades are related to long stall events where MBP undergoes specific and reproducible structural rearrangements. To clarify the origin of the stalls, the stick-and-slip translocation is compared to mechanical unfolding pathways obtained via steered molecular dynamics. This comparison clearly shows the translocation pathway to significantly differ from free-space unfolding dynamics and strongly suggests that stalling events are preferentially determined by the MBP regions with higher density of long-range native interactions. This result might constitute a possible criterion to predict a priori some statistical features of protein translocation from the structural analysis. © 2012 American Chemical Society
Protein translocation in narrow pores: Inferring bottlenecks from native structure topology
No full textCoarse-grained simulations of protein translocation across narrow pores suggest that the transport is characterized by long stall events. The translocation bottlenecks and the associated free-energy barriers are found to be strictly related to the structural properties of the protein native structure. The ascending ramps of the free-energy profile systematically correspond to regions of the chain denser in long range native contacts formed with the untranslocated portion of the protein. These very regions are responsible for the stalls occurring during the protein transport along the nanopore. The decomposition of the free energy in internal energy and entropic terms shows that the dominant energetic contribution can be estimated on the base of the protein native structure only. Interestingly, the essential features of the dynamics are retained in a reduced phenomenological model of the process describing the evolution of a suitable collective variable in the associated free-energy landscape
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
