Combined use of homologous fascia lata graft and acellular dermal substitute for the repair of a complex abdominal wound
No full textFull-thickness abdominal wall defects complicated with bowel exposure require a stable reconstruction that may be achieved with mesh repair, muscle rotational flaps, pedicled flaps, freeflaps or any combination of these techniques. We present a case report of a complex abdominal wound caused by a gunshot trauma in an elderly patient. His general health condition and local disruption of the left rectus, external, internal oblique and transverse abdominis muscles prevent local flaps or major surgical reconstruction procedures. The combined use in multiple stages of a homologous fascia lata graft, negative pressure therapy and acellular dermal substitute template followed by skin graft allowed stable wound healing. Level of Evidence: Level V, therapeutic stud

No full textAlternative Conduits for Microvascular Anastomoses.
No full textThrombotic events in vascular substitutes are the main cause of obliteration of most microvascular prostheses and subsequent failure of microvascular anastomoses. The development of new biomaterials for vascular replacement aims to obtain an ideal graft for microvascular surgery. Completely bioresorbable vascular prostheses with the capacity to induce regeneration and growth of a new vascular segment seem to overcome the limitations of contemporary artificial prostheses, mostly made of artificial materials and lacking the capacity to grow and be remodeled. Autologous vessels are currently the most used material for small-diameter arterial replacement. Immune acceptance is a major advantage offered by this technique, but the time required is a limitation in emergency surgery. The need for a prosthetic graft that would have the same properties as a small-diameter conduit has led investigators to pursue many avenues in vascular biology. This article details the development of microvascular synthetic prostheses, clarifying the current status and the future aim
Gershom Scholem e Auschwitz
No full textThe article offers a new look on Gershom Scholem's position on the significance of the Shoah, analysing his complex relationship wtih Hannah Arendt, his public stance in the affaire Eichmann, his correspondence with Walter Benjamin and, especially, his autobiography. In a very peculiar passage, Scholem seems to say that as a child in Wilhelmine Berlin he could not know that Oswiecim was Auschwitz. What he actually meant, since at face value his sentence is less than credible, is that he could not know what would have become of this remote place at the border between the Austrian Empire and Czarist Russia. I question even that revised meaning, since, in his speculations about the destiny of the Jews in Europe, he had anticipated their tragic end. What is left is the peculiar shame of the survivor, who chose emigration in order to save himself a decade before Hitler, but could not save his brother, nor his friends, from deadly persecution
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
"Who are those children?" Die Aufarbeitung des Kindertransports in ausgewählten Texten
No full textDas Thema des Kindertransports als eins der großen Exil-Narrative endet nicht mit der 1. Generation, mit den ZeitzeugInnen. Viele davon empfanden es als ihre Pflicht, zu berichten, was sie erlebt haben und die Geschichte ihrer Familie zu rekonstruieren, was wohl der Erwartung des Lesepublikums ent- sprach. Einige der ZeitzeugInnen schrieben auch Autobiographien, in denen sie sich von ihrer eigenen Geschichte distanzieren konnten, sich nicht mehr nur an den historischen Fakten orientierten und dadurch einen stärkeren Emo- tionsausdruck für das Erlebte entwickelten, das erlebte Trauma durcharbeiten und nachvollziehbar machen konnten. Die Erfahrung des unausgesprochenen Traumas bleibt – wenn auch in veränderter Weise – auch in der Erinnerung der 2. und 3. Generation, wie die Texte, die dazu seit den 2000er Jahren veröffent- licht wurden, beweisen.
In fiktionalen Texten greifen AutorInnen, die keine Zeitzeugen sind, das Thema des Kindertransports auf und entwickeln Aspekte davon in einem lite- rarischen Rahmen, in dem die historische Wahrheit nicht in direkter Form in den Text hineinspielen muss
