“Who was the Lion?” Sibylle Lewitscharoff’s "Blumenberg"
No full textThe eponymous protagonist of Sibylle Lewitscharoff’s novel "Blumenberg" (2011) pays a tribute to Hans Blumenberg, one of the recent thinkers who have most appealed to non-specialists—not least because of his immense erudition. The book "Lions", to which the novel openly refers (5), is crucial to understanding how Lewitscharoff approaches Blumenberg’s life and thought in her book. In fact, although the author claims in her acknowledgments that “any attempts to find correct Blumenberg quotations will be in vain” (219), she nevertheless reveals herself well acquainted with fundamental aspects of his theories such as the notion of fictionality, the metaphor of the cave and the thesis of the legitimacy of the New Age. Echoes of his phrases and formulations, partial quotations of sentences from his works, can be easily discerned between the lines. During the feline’s visit to Blumenberg, the sphere of the wonderful and miraculous breaks into the philosopher’s somewhat limited and ordered scholarly existence, becoming a source of irritation
Apoptosis in human sperm as a quality marker for a new diagnostic approach of infertile patients
Full text linkThe quality of the sperm DNA is one of the most important molecular markers of male reproductive potential (Bosco, L et al., 2018, Environ Toxicol Pharmacol 58:243-249). The aim of this study was to evaluate sperm DNA fragmentation according to morphology, to predict the probability of selecting a sperm with normal morphology and intact DNA. An observational study was performed on 70 patients with oligoasthenoteratozoospermia. Sperm DNA Fragmentation Index (DFI) and semen parameters such as sperm density, motility and morphology were evaluated in all patients. DFI was calculated using the in situ TUNEL assay. DFI can be determined and thus used as a marker of sperm quality for a diagnostic approach of infertile patients. For each patient, out of the total of sperm DFI, we calculated the proportion between sperm with normal morphology and with abnormal morphology. Among 35 patients (A Group), the DFI was inferior than 15% (average value was 8.1%), while 35 patients (B Group) had a DFI higher than 15% (average value was 24.6%). When the analysis was restricted only to spermatozoa with normal morphology, it was observed that among patients of B Group the DFI value was 13.6%, while in A Group the average was 2.2%. DFI calculated on sperm of normal morphology can provide an important information on the risk of injecting, during ICSI procedure, a sperm with normal morphology but with DNA fragmentation. This risk is higher if the semen sample has a baseline DFI higher than 15%
Introduction. Exploring the Great Divide. Animals and Humans in the German-Language Literature
No full textThe recent emergence of the discipline of literary animal studies regards literature in itself as constitutive element of a history of knowledge. The discipline has led not only to the expansion of the corpus of texts traditionally connected with animals, but also established new concepts and methods for revising conventional cultural dichotomies (subject and object, human and animal). The 10 essays collected in this volume are devoted to a wide range of case studies on the relationship between animality and poetics in German-speaking literature since the 18th century. They display a variety of theoretical and methodological approaches to a number of texts packed with references to animals, considered not primarily as objects of literature, but as agents endowed with an active role in the production of literature, and which have left repressed or forgotten traces in texts
Anthropozän und Klimawandel in der zeitgenössischen deutschen Literatur: Ilija Trojanows „EisTau“
No full textEin Beispiel für eine narrative Verfahrensweise, die sich mit all den mit dem Klimawandel zusammenhängeden Aspekten auseinandersetzt (ob auf eine gelungene oder ungelungene Weise mag es dahingestellt bleiben) und dabei über mögliche gattungsspezifische Eingliederungsschwierigkeiten hinwegsetzt, ohne sie jedoch auszublenden, liefert Iljia Trojanows Roman EisTau (2011). Der vorliegende Beitrag befasst sich mit diesem Text und mit Trojanows Selbstpositionierung als engagierter Autor
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
