Die Universität Potsdam verwaltet seit 2015 einen DFG-geförderten Publikationsfonds. In den Publikationsjahren 2015 und 2017 wurden Outputanalysen durchgeführt. Open Access ist seit 2018 ein zentraler Bestandteil des Mittelverteilungsmodells. Der Artikel thematisiert die zentralen Erkenntnisse der letzten fünf Jahre und illustriert die entstandene Infrastruktur. Außerdem werden aktuelle Herausforderungen und mögliche Lösungsansätze der Transformation auf dem Weg hin zu 100 Prozent Open Access thematisiert.
Die Universität Potsdam hat 2018 zum zweiten Mal erfolgreich am Times Higher Education-Ranking (THE-Ranking) teilgenommen. Hierfür wurde erneut das Publikationsaufkommen inklusive der Verbreitung der IDs von Autorinnen und Autoren, wie bspw. ORCiD, Researcher-ID oder Google Scholar-ID, ermittelt. Die aus den Erkenntnissen der ersten bibliometrischen Output-Analyse abgeleiteten Maßnahmen wurden nun hinsichtlich ihrer Wirksamkeit beurteilt. Der vorliegende Artikel vergleicht die Ergebnisse beider Analysen und thematisiert die Entwicklungen und Implikationen seit dem Ergreifen der ersten Maßnahmen.
White adipose tissue (WAT) is actively involved in the regulation of whole-body energy homeostasis via storage/release of lipids and adipokine secretion. Current research links WAT dysfunction to the development of metabolic syndrome (MetS) and type 2 diabetes (T2D). The expansion of WAT during oversupply of nutrients prevents ectopic fat accumulation and requires proper preadipocyte-to-adipocyte differentiation. An assumed link between excess levels of reactive oxygen species (ROS), WAT dysfunction and T2D has been discussed controversially. While oxidative stress conditions have conclusively been detected in WAT of T2D patients and related animal models, clinical trials with antioxidants failed to prevent T2D or to improve glucose homeostasis. Furthermore, animal studies yielded inconsistent results regarding the role of oxidative stress in the development of diabetes. Here, we discuss the contribution of ROS to the (patho)physiology of adipocyte function and differentiation, with particular emphasis on sources and nutritional modulators of adipocyte ROS and their functions in signaling mechanisms controlling adipogenesis and functions of mature fat cells. We propose a concept of ROS balance that is required for normal functioning of WAT. We explain how both excessive and diminished levels of ROS, e.g. resulting from over supplementation with antioxidants, contribute to WAT dysfunction and subsequently insulin resistance.

The article presents first results of a pilot study on the syntactic changes in Polish as a language contact in Germany. On the base of the experimental data tests the study examines the syntactic changes in Polish of two diaspora-generations: the so called forgetters and the incomplete learners. The article focuses on the questions: how the situation of languages in contact influences the syntactic changes in the heritage language (Polish) and which status have those syntactic transferences. Other linguistic and sociolinguistic factors, capable to cause the language change in the situation of language contact, are also discussed in the article.
The role of serum amyloid A and sphingosine-1-phosphate on high-density lipoprotein functionality
(2017)
The high-density lipoprotein (HDL) is one of the most important endogenous cardiovascular protective markers. HDL is an attractive target in the search for new pharmaceutical therapies and in the prevention of cardiovascular events. Some of HDL’s anti-atherogenic properties are related to the signaling molecule sphingosine-1-phosphate (S1P), which plays an important role in vascular homeostasis. However, for different patient populations it seems more complicated. Significant changes in HDL’s protective potency are reduced under pathologic conditions and HDL might even serve as a proatherogenic particle. Under uremic conditions especially there is a change in the compounds associated with HDL. S1P is reduced and acute phase proteins such as serum amyloid A (SAA) are found to be elevated in HDL. The conversion of HDL in inflammation changes the functional properties of HDL. High amounts of SAA are associated with the occurrence of cardiovascular diseases such as atherosclerosis. SAA has potent pro-atherogenic properties, which may have impact on HDL’s biological functions, including cholesterol efflux capacity, antioxidative and anti-inflammatory activities. This review focuses on two molecules that affect the functionality of HDL. The balance between functional and dysfunctional HDL is disturbed after the loss of the protective sphingolipid molecule S1P and the accumulation of the acute-phase protein SAA. This review also summarizes the biological activities of lipid-free and lipid-bound SAA and its impact on HDL function.

This article explores a recent performance of excerpts from T.S. Eliot’s Four Quartets (1935/36–1942) entitled Engaging Eliot: Four Quartets in Word, Color, and Sound as an example of live poetry. In this context, Eliot’s poem can be analysed as an auditory artefact that interacts strongly with other oral performances (welcome addresses and artists’ conversations), as well as with the musical performance of Christopher Theofanidis’s quintet “At the Still Point” at the end of the opening of Engaging Eliot. The event served as an introduction to a 13-day art exhibition and engaged in a re-evaluation of Eliot’s poem after 9/11: while its first part emphasises the connection between Eliot’s poem and Christian doctrine, its second part – especially the combination of poetry reading and musical performance – highlights the philosophical and spiritual dimensions of Four Quartets.
Kritische Anthropologie?
(2016)
This article compares Max Horkheimer’s and Theodor W. Adorno’s foundation of the Frankfurt Critical Theory with Helmuth Plessner’s foundation of Philosophical Anthropology. While Horkheimer’s and Plessner’s paradigms are mutually incompatible, Adorno’s „negative dialectics“ and Plessner’s „negative anthropology“ (G. Gamm) can be seen as complementing one another. Jürgen Habermas at one point sketched a complementary relationship between his own publicly communicative theory of modern society and Plessner’s philosophy of nature and human expressivity, and though he then came to doubt this, he later reaffirmed it. Faced with the „life power“ in „high capitalism“ (Plessner), the ambitions for a public democracy in a pluralistic society have to be broadened from an argumentative focus (Habermas) to include the human condition and the expressive modes of our experience as essentially embodied persons. The article discusses some possible aspects of this complementarity under the title of a „critical anthropology“ (H. Schnädelbach)
This article first outlines different ways of how psycholinguists have dealt with linguistic diversity and illustrates these approaches with three familiar cases from research on language processing, language acquisition, and language disorders. The second part focuses on the role of morphology and morphological variability across languages for psycholinguistic research. The specific phenomena to be examined are to do with stem-formation morphology and inflectional classes; they illustrate how experimental research that is informed by linguistic typology can lead to new insights.
