There is a debate over the association between low testosterone levels in body fluids and the occurrence of chronic periodontitis (CP). The aim of the present systematic review was to assess whether low testosterone levels in body fluids reflect CP. In order to identify studies relevant to the focus question: “Is there a relationship between low testosterone levels in body fluids and CP?” an electronic search without time or language restrictions was conducted up to June 2016 in indexed databases using different keywords: periodontitis, chronic periodontitis, periodontal diseases, testosterone, and gonadal steroid hormones. A total of eight studies were included in the present systematic review. The number of study participants ranged from 24 to 1,838 male individuals with ages ranging from 15 to 95 years. Seven studies measured testosterone levels in serum, two studies in saliva, and one study in gingiva. Four studies reported a negative association between serum testosterone levels and CP. Two studies reported a positive association between decreased testosterone levels in serum and CP. Increased levels of salivary testosterone among patients with CP were reported in one study; whereas one study reported no significant difference in the concentration of salivary testosterone between patients with and without CP. One study identified significant increase in the metabolism of testosterone in the gingiva of patients with CP. Within the limits of the evidence available, the relationship between low testosterone levels and CP remains debatable and further longitudinal studies and control trials are needed.
Mapping a public discourse with the tools of computational text analysis comes with many contingencies in the areas of corpus curation, data processing and analysis, and visualisation. However, the complexity of algorithmic assemblies and the beauty of resulting images give the impression of ‘objectivity’. Instead of concealing uncertainties and artefacts in order to tell a coherent and all-encompassing story, retaining the variety of alternative assemblies may actually strengthen the method. By utilising the mobility of digital devices, we could create mutable mobiles that allow access to our laboratories and enable challenging rearrangements and interpretations.
In the past few years a multidisciplinary team of scholars based at Goethe Universität Frankfurt has been involved in the development of three projects: the research project “Political language in the Middle Ages: Semantic Approaches”, and two online platforms, “Computational Historical Semantics” and “eHumanities Desktop”. These are closely related to each other, as they bring together historical research on Latin medieval texts and Digital Humanities. This article will offer an overview of the projects, focusing particularly on the digital tools which have been developed by the team.
Im Rahmen des Kongresses „Literaturwissenschaften in Frankfurt, 1914 – 1945“, der von Bernd Zegowitz (Germanistik) und Frank Estelmann (Romanistik) am 20. und 21. Juni 2014 an der Universität Frankfurt am Main organisiert wurde, gaben 13 Vortragende an zwei Tagen Einblicke sowohl in die Geschichte als auch in exemplarische Werke von Literaturwissenschaftlern, die in der Zeit zwischen der Universitätsgründung im Jahr 1914 und dem Ende des Nationalsozialismus 1945 an der Universität Frankfurt lehrten und forschten.

Biografie und Lebenslauf stehen sich nicht mehr antonymisch gegenüber, sondern treten ins Verhältnis zueinander. Auf der theoretischen Grundlage des erweiterten kategorialen Rahmens ist ein breites Forschungsfeld entstanden, das Lehr-Lern-Prozesse aus der Perspektive der Biografie- und Lebenslaufforschung untersucht. Diese Ausgabe referiert auf diese Forschungslage. Sie knüpft damit an die Themenhefte des REPORT „Biografieforschung und biografisches Lernen“ und „Biografie und Bildung“ an, legt aber nun den Schwerpunkt auf die Verknüpfung von Lebenslauf und Biographie im Hinblick auf das Lernen Erwachsener in und außerhalb von Institutionen.
This paper provides a theoretical assessment of gestures in the context of authoring image-related hypertexts by example of the museum information system WikiNect. To this end, a first implementation of gestural writing based on image schemata is provided (Lakoff in Women, fire, and dangerous things: what categories reveal about the mind. University of Chicago Press, Chicago, 1987). Gestural writing is defined as a sort of coding in which propositions are only expressed by means of gestures. In this respect, it is shown that image schemata allow for bridging between natural language predicates and gestural manifestations. Further, it is demonstrated that gestural writing primarily focuses on the perceptual level of image descriptions (Hollink et al. in Int J Hum Comput Stud 61(5):601–626, 2004). By exploring the metaphorical potential of image schemata, it is finally illustrated how to extend the expressiveness of gestural writing in order to reach the conceptual level of image descriptions. In this context, the paper paves the way for implementing museum information systems like WikiNect as systems of kinetic hypertext authoring based on full-fledged gestural writing.
