Background: The health status, health awareness and health behavior of persons with a migration background often differ from the autochthonous population. Little is known about the proportion of patients with a migration background (PMB) that participate in primary care studies on oral antithrombotic treatment (OAT) in Germany, and whether the quality of their antithrombotic care differs from patients without a migration background. The aim of this paper was to use the results of a cluster-randomized controlled trial (PICANT) to determine the proportion of PMB at different stages of recruitment, and to compare the results in terms of sociodemographic characteristics and antithrombotic treatment.
Methods: This study used screening and baseline data from the PICANT trial on oral anticoagulation management in GP practices. For this analysis, we determined the proportion of PMB during the recruitment period at stage 1 (screening of potentially eligible patients), stage 2 (eligible patients invited to participate in the trial), and stage 3 (assessment of baseline characteristics of patients participating in the PICANT trial). In addition, we compared patients in terms of sociodemographic characteristics and quality of anticoagulant treatment. Statistical analysis comprised descriptive and bivariate analyses.
Results: The proportion of PMB at each recruitment stage declined from 9.1% at stage 1 to 7.9% at stage 2 and 7.3% at stage 3). A lack of German language skills led to the exclusion of half the otherwise eligible PMB. At stages 1 and 3, PMB were younger (stage 1: 70.7 vs. 75.0 years, p<0.001; stage 3: 70.2 vs. 73.5 years, p = 0.013), but did not differ in terms of gender. The quality of their anticoagulant care was comparable (100.0% vs. 99.1% were receiving appropriate OAT, 94.4% vs. 95.7% took phenprocoumon, or warfarin, and the most recent INR measurement of 60.8% vs. 69.3% was within their individual INR range).
Conclusions: In the potentially eligible population and among participants at baseline, the quality of anticoagulant care was high in all groups of patients, which is reassuring. To enable the inclusion of more PMB, future primary care research on OAT in Germany should address how best to overcome language barriers. This will be challenging, particularly because the heterogeneity of PMB means the resulting sample sizes for each specific language group are small.

Feasibility, design and sensitivity studies on innovative nuclear reactors that could address the issue of nuclear waste transmutation using fuels enriched in minor actinides, require high accuracy cross section data for a variety of neutron-induced reactions from thermal energies to several tens of MeV. The isotope 241Am (T1/2= 433 years) is present in high-level nuclear waste (HLW), representing about 1.8 % of the actinide mass in spent PWR UOx fuel. Its importance increases with cooling time due to additional production from the β-decay of 241Pu with a half-life of 14.3 years. The production rate of 241 Am in conventional reactors, including its further accumulation through the decay of 241Pu and its destruction through transmutation/incineration are very important parameters for the design of any recycling solution. In the present work, the 241 Am(n,f) reaction cross-section was measured using Micromegas detectors at the Experimental Area 2 of the n_TOF facility at CERN. For the measurement, the 235U(n,f) and 238U(n,f) reference reactions were used for the determination of the neutron flux. In the present work an overview of the experimental setup and the adopted data analysis techniques is given along with preliminary results.
Introduction: Reliable and cost-effective diagnostics for hepatitis E virus (HEV) infection are necessary. The aim of our study was to investigate which diagnostic test is most accurate to detect HEV infection in immunocompetent and immunosuppressed patients in a real world setting. Patients and Methods: We performed a retrospective analysis of 1165 patients tested for HEV antibodies and HEV PCR at the same time point. Clinical, laboratory and virological data were taken from patient charts. HEV IgA was measured in a subgroup of 185 patients. Results: HEV RNA was detectable in 61 patients (5.2%); most of them (n = 49, 80.3%/n = 43, 70.5%) were HEV IgM+ and IgG+; however, 12 patients (19.6%) were HEV RNA positive/HEV IgM negative and 17 patients (27.8%) were HEV RNA positive/HEV IgG negative. Ten HEV RNA positive patients (16.4%) had neither HEV IgG nor IgM antibodies. Importantly, all of them were immunosuppressed. HEV IgA testing was less sensitive than HEV IgM for HEV diagnosis. Conclusions: HEV infection can be overlooked in patients without HEV specific antibodies. Performing PCR is necessary to diagnose or exclude HEV infection in immunocompromised hosts. In immunocompetent patients, a screening based on HEV antibodies (IgG/IgM) is sufficient.
Human cytomegalovirus (CMV) is a significant cause of morbidity and mortality in patient groups at risk. We have previously shown that the anti-CMV IgG seroprevalence in an urban region of Germany has changed over the last decades. Overall, a decline from 63.7 to 57.25% had been observed between 1988–1997 and 1998–2008 (p < 0,001). Here, we continuously follow the trends to the most recent decade 2009 to 2018. In a retrospective analysis, we determined the seroprevalence of CMV IgG antibodies in our patient cohort, stratified by gender and selected groups at risk (e.g., patients with HIV infection; women of childbearing age). The overall prevalence of anti-CMV IgG non-significantly declined further from 57.25% in 1998–2008 to 56.48% in 2009–2018 (p = 0.881). Looking at gender differences, overall CMV seroprevalence in males declined to 52.82% (from 55.54% in 1998–2008; p = 0.0254), while it non-significantly increased in females to 59.80%. The high seroprevalence in patients with a known HIV infection further increased from 87.46% in 1998–2008 to 92.93% in the current period (p = 0.9999). In women of childbearing age, no significant changes over the last three decades could be observed. The CMV seroprevalence in oncological patients was determined to be 60.64%. Overall, the former significant decline of CMV seroprevalence between the decades 1988–1997 and 1998–2008 in this urban region of Germany slowed down to a non-significant decrease of 0.77% (1998–2008 vs. 2009–2018). This might be an indicator that CMV seroprevalence has reached a plateau.
Die Übersetzung, insbesondere die literarische, ist vor allem eine Art Kulturübertragung. Neben der Beherrschung der Sprachen setzt sie die Kenntnis des Allgemeinen und Besonderen des Landes wie Kultur, Tradition, Glauben, geschichtliche und gesellschaftliche Begebenheiten und auch soziale Strukturen voraus. Wenn die Sprachen und Kulturen tiefgreifend wahrgenommen werden, können die übersetzten Texte die Adressaten erreichen, d.h., dass die Ausgangssprache und -kultur für die Zielrezipienten verständlich sein können. So wird der Übersetzer als Kulturträger angenommen. Cornelius Bischoff ist beispielsweise ein wohlbekannter Name für den deutschen und türkischen Literaturkreis. Er ist vor allem bekannt als "der deutscheste Türke und der türkischste Deutsche" sowie als eine Brücke zwischen Deutschland und der Türkei. Das Ziel der vorliegenden Arbeit ist es, Cornelius Bischoff, einen Kulturträger zwischen der deutschen und türkischen Übersetzung, zu behandeln. Als ein "Haymatloser" fand er in der Türkei die Möglichkeit, die türkische Sprache und Kultur wesentlich kennenzulernen und viele türkische Werke ins Deutsche zu übersetzen. Als ein Übersetzer trug er zuallererst dazu bei, die türkische Literatur, die bedeutenden türkischen Schriftsteller, die türkische Kultur und Tradition sowie den türkischen Sprachgebrauch in Deutschland bekannt zu machen. In der vorliegenden Arbeit wird die Besonderheit Bischoffs in der Übersetzungswelt im Hinblick auf drei Aspekte diskutiert: zuerst im Hinblick auf den Zusammenhang seiner Wurzeln in der Türkei und im Türkischen - schon in seinen Wurzeln, besonders mütterlicherseits, wurde das Türkische verinnerlicht -, dann auf die in der Türkei verbrachten Jahre - die Jahre, in denen er "haymatlos" genannt wurde - und zuletzt auf die Wahrnehmung und Aneignung der türkischen Sprache, Kultur und Gesellschaft - was auf ihn lebenslang einwirkte. In diesem Kontext wird versucht, sein Leben, seine Werke und seine Wirkung im Rahmen der übersetzerischen Tätigkeit zu analysieren.
Genel Edebiyat Biliminin bir dalı olan "Karşılaştırmalı Edebiyat", farklı dillerde yazılmış edebi eserlerin, benzerlik ve farklılıklar yönünden karşılaştırılmasıdır. Karşılaştırmaya dayalı analizlerdeki amaç, iki ya da daha fazla eserin, biçim, üslup, motif ve ya tema gibi edebi unsurlar açısından ortak ve ya farklı öğelerini belirlemektir. Edebi metinlerde kullanılan dilsel öğeleri inceleme alanı olan "Biçembilim", okuyucunun metinleri anlamasını sağlayan en önemli araçlardan biridir. Karşılaştırmalı Edebiyat bilimi kapsamında çevirinin önemi yadsınamaz ve bir metin ile çevirisi, mukayeseli çalışma alanlarından biridir. Bu araştırmanın özünü, kaynak metin ve erek metin arasındaki benzerlik ve farklılıkları örneklendirmek adına karşılaştırmalı edebi çeviri örneği oluşturmaktadır. Bu bağlamda, bu çalışmada, William Shakespeare'in "Sonnet 66" şiirinin Türk edebiyatçı Can Yücel tarafından "66. Sone" olarak çevirisinin, Katharina Reiss'in "içerik odaklı" çeviri modeline dayanarak nasıl yorumlandığı incelenmiştir.
Die vorliegende Studie bietet eingangs allgemeine Erwägungen über die Rolle des literarischen Kanons im 21. Jahrhundert und über eine mögliche Redefinition von Rollen der Akteur/innen der Kanonisierungsprozesse. Auf dieser Grundlage wird ein Konzept entworfen, dessen Ziel es ist, die Nützlichkeit und Notwendigkeit einer neuen Sicht auf vergessene und nichtkanonisierte Texte zu zeigen. Die Materialbasis bildet diesbezüglich die deutschgeschriebene Literatur aus der Mährischen Walachei, die auch in groben Zügen als literarisches Phänomen skizziert wird. Analysiert werden ausgewählte poetische Werke der aus diesem Gebiet der Böhmischen Länder stammenden und weitgehend unbekannten Autorin Susanne Schmida (1894–1981).
Der in Prag situierte Roman Café Slavia (1985) von Ota Filip, einem deutschschreibenden Autor, der in den 1970er Jahren die Tschechoslowakei aus politischen Gründen verlassen musste und sich nach seiner Ausbürgerung in München niederließ, erzählt die wechselvolle Geschichte Mitteleuropas vom Anfang des 20. Jahrhunderts bis zum Prager Frühling 1968, eingeleitet durch eine Rahmenhandlung, die sich an der Karlsbrücke in Prag abspielt. Der Beitrag versucht, die Symbolik der im Roman zentralen "Brücke" in ihrer Vielschichtigkeit offenzulegen. Im Mittelpunkt der Analyse steht die Brücke als Erzählkonstruktion, die den Blick von der Gegenwart aus auf die Vergangenheit richtet und dabei sowohl die "kleine" als auch die "große" Geschichte im Blick behält. Dabei bekommt sie als topographischer Verbindungsort zwischen dem rechten und linken Moldauufer weitere Bedeutungszuschreibungen und steht für die Überschreitung nicht nur zwischen Raum und Zeit, sondern auch zwischen Faktualität und Fiktionalität.
Background: The newly introduced German pediatric screening examination at the end of the third year of life (U7a) incorporates visual function testing in particular; there is no ophthalmic screening during childhood in Germany. The purpose of this study is to investigate the relationship between participation in U7a and visual function at the preschool health examination (PHE) in the sixth year of life. Methods: This study evaluated PHE data from school enrollment years 2009/2010 to 2014/2015 of Rhineland-Palatinate, Germany. Visual acuity (VA) at PHE was assessed with Rodenstock visual acuity test device (tumbling E) wearing glasses if present. The relationship between participation in U7a and VA <0.7 at PHE was calculated for reduced monocular and binocular VA using multiple logistic regression adjusted for potential confounders. Results: Data from 189,704 children (91,041 girls) in 35 out of 36 districts were included. The first children to participate in U7a were enrolled in 2011/2012 school year. In total, 90,339 children (47.6%) had U7a before PHE, while 99,365 (52.4%) had not. VA <0.7 in at least one eye was measured at PHE in 8429 (4.4%) children, and in both eyes in 4345 (2.3%) children. Participation in U7a was not associated with VA <0.7 at PHE (odds ratio 0.99; 95% confidence interval: 0.94–1.04). Conclusions: The proportion of children with VA <0.7 at PHE was high. No beneficial effect of newly introduced German U7a pediatric screening examination was found for reduced VA at PHE.
Yoko Tawada é um dos nomes mais importantes da Literatura Contemporânea. Seu projeto literário trata das questões acerca da identidade através do processo de estranhamento. Em "Das nackte Auge" tem-se uma jovem garota vietnamita, cujo nome nunca é revelado, que, por conta de um engano, desembarca na cidade de Paris. Ela não fala francês e se vê incapaz de compreender o meio estrangeiro que a cerca. No entanto, encontra no cinema, mais especificamente nas personagens de Catherine Deneuve, um local de refúgio e identificação. Cada capítulo trata de um filme cuja narrativa progressivamente se mistura e influencia a narrativa da personagem. Já no primeiro capítulo, "Repulsion", uma referência ao filme de Roman Polanski, pode-se perceber diversos elementos comuns à obra fílmica e de fundamental importância na construção de "Das nackte Auge". Tal construção intermidiática é apresentada com o objetivo de suscitar questões acerca do sujeito contemporâneo e seu olhar (desnudado) sobre o estranho, o estrangeiro.
Combining the methods of linguistics and literary criticism, this article takes a fresh look at two texts that have been analysed ad nauseam: Henry James’s The Portrait of a Lady and Edith Wharton’s The Age of Innocence. I use James’s late style as a touchstone to compare and contrast the two texts. Analysing syntax by means of close textual analysis of the novels’ opening paragraphs as well as their metaphorical language, and employing the corpus analysis programme AntConc to survey the entire texts, I aim to show that James’s 1880 text anticipates his late style and Wharton’s 1920 text appropriates it to suit her own agenda. However, in respectively anticipating and appropriating this style, James and Wharton create different effects. James intensifies his female protagonist’s ‘world of thought and feeling’ (Eliot 1963: 56), creating a fictional world with literary equality for both genders, while Wharton subverts gender roles in a scathing critique of Gilded Age society, which did not allow for this other ‘world of thought and feeling’. In addition to positioning both novels as feminist, this article compares Wharton’s writing to James’s, but without presupposing the latter’s influence on the former. Instead, acknowledging the fluidity of style, I aim to put forward a convincing case that there are subtle differences that make these authors’ styles Jamesian and Whartonian, respectively.
The shared communicative act of theatrical texts in performance: a relevance theoretic approach
(2020)
This article adopts a relevance theoretic approach to meaning making in theatrical texts and performances. Theatrical texts communicate immediately to multiple audiences: readers, actors, directors, producers, and designers. They communicate less directly to the writer’s ultimate audience – the playgoer or spectator – through the medium of performance. But playgoers are not passive receptacles for interpretations distilled in rehearsal, enacted through performance, or developed in study and reflection. Rather, in the framework of communication postulated by relevance theory, the audience is an active participant in making meaning. I will briefly review a range of approaches to meaning making in theatre, and then outline my view of a relevance theoretic account of the vital contributions of the audience in constructing the interpretation of performance, treating it as a communicative act.
"You don’t mind my calling you Harry?" : Terms of address in John Updike’s "Rabbit" tetralogy
(2020)
This paper examines the use of address terms in John Updike’s Rabbit tetralogy (Updike 1995). The first part of the analysis provides a comprehensive overview of the great variety of terms used to address the protagonist, Harry Angstrom, in the decades covered by the novels. The second part focuses on two important side characters, Reverend Eccles and Harry’s mother-in-law. It demonstrates how address term usage with these two characters reflects ongoing changes in their relationship with Harry. The main aim of the paper is to demonstrate the potential of fictional data for the study of address terms and, in return, to capture the manifold functions of address terms as a literary device in fiction.
Four main informational elements have been suggested and studied as central aspects of narrative discourse: causality, character, location, time. The research that scholars have previously undertaken on these aspects has been primarily on Indo-European languages, and more specifically on the European side of that language family. The linguistic limitations have indicated that character is the aspect of narrative that readers/listeners attend to most closely. However, in examining narrative discourses from non-Indo-European languages, challenges to the presumed primacy of character emerge. In a partial report on field work conducted in Borneo in 2012-2015, I compare and contrast patterns in the rankings of the four main aspects of narrative in three languages, English, Hobongan and Daqan. I also note the strategies by which the languages make their respective rankings clear, including focus particles (Hobongan), specificity of description (each), and amount of information provided about the aspects (each). I suggest that analyses of the patterns and rankings of information in narrative be included in typological categorizations and linguistic descriptions of languages.
In dieser Arbeit soll der Einsatz von Filmen als audiovisuelles Unterrichtsmaterial im Fremdsprachenunterricht erörtert werden. Bei räumlichen und kulturellen Entfernungen zum Zielsprachenland ermöglicht Filmmaterial sprachliche und landeskundliche Inhalte in den Unterricht zu bringen. In diesem Rahmen bieten Filme, die Alltagssprache und Alltagsthemen des Zielsprachenlandes präsentieren, vielfältige Einsatzmöglichkeiten zur Erweiterung der sprachlichen und kulturellen Kompetenzen von Lernenden. Kein anderes Medium verfügt über ein so hohes Potential, die Neugierde der Lerner auf das Zielsprachenland und seine Menschen zu wecken, die Lerner zu motivieren, Emotionen auszulösen und Sprech- und Diskussionsanlässe zu schaffen. Der Einsatz von Filmen leistet einen wichtigen Beitrag zur Gestaltung von effizientem Fremdsprachenunterricht.
Der vorliegende Artikel befasst sich mit den Schwierigkeiten der Übersetzung von Humor und verschiedenen möglichen Übersetzungsstrategien für die Übertragung von Humor von einer Sprache bzw. Kultur in eine andere. Er enthält ferner eine Fallstudie, die sich mit den sehr erfolgreichen Synchronisationen des Synchronregisseurs und -sprechers Rainer Brandt in den 1970er/ 80er Jahren befasst. Dabei wird gezeigt, dass Kreativität und Mut zum Risiko in manchen Fällen sogar die synchronisierte Fassung erfolgreicher als das Original machen können. Es zeigt sich also, dass es sinnvoll ist, auch in der Synchronisation öfter vom Postulat der unbedingten Treue zum Original abzuweichen.

Im Rahmen einer Kartierung und FFH-Bewertung von für den Klettersport genutzten Felsen im Werra-Meißner-Kreis wurde Asplenium fontanum (Jura-Streifenfarn) im Gebiet des "Ellersteines" nordöstlich der Ortschaft Hundelshausen bei Witzenhausen 2014 mit einer Pflanze erstmals nachgewiesen (Rasterfeld 4625/3). Vorher galt der Jura-Streifenfarn, eine in Deutschland sehr seltene Art, in Hessen seit circa 1950 als erloschen. Mit den Populationen in der Schwäbischen Alb, am Kyffhäuser und bei Wolfstein (Rheinland-Pfalz) bildete dieser A.-fontanum-Fund die bekannten Vorkommen der letzten Jahre in Deutschland. Bei dem hessischen A.-fontanum-Vorkommen im Bereich des Ellerstein-Felskomplexes handelte sich um das nördlichste Vorkommen an einem natürlichen Standort in Deutschland. Der Wuchsort des Farnes befindet sich in einem Buchenwald auf einem kleinen Dolomit-Felsblock vor einer Felswand, die zum Bouldern genutzt wird (Klettern ohne Seilsicherung in Absprunghöhe). Aufgrund der Position und Ungeschütztheit des Wuchsortes erschien der Farn ausgesprochen gefährdet gegenüber mechanischem Abrieb durch Kletterer. Der von 2014 bis 2018 beobachtete Farn trieb 2019 nicht mehr aus. Die Ursachen dafür sind nicht eindeutig. So könnte die extreme und außergewöhnlich lang anhaltende Dürre im Jahr 2018 mit anschließenden meist zu trockenen Winter- und Frühjahrsmonaten verantwortlich sein. Verbiss oder negative Auswirkungen des Klettersports auf den Farn sind jedoch nicht auszuschließen. Daher werden die für den Farn im Ellerstein-Felskomplex festgestellten Gefährdungen in der vorliegenden Arbeit diskutiert und Empfehlungen für Artenhilfsmaßnahmen gegeben. Insbesondere wird ein vollständiger Verzicht auf Klettern und ein Aussetzen der Waldbewirtschaftung am Wuchsort und an potenziellen Siedlungsstellen der unmittelbaren Umgebung vorgeschlagen. Entsprechende Maßnahmen gelten sinngemäß für andere sehr seltene oder stark gefährdete Pflanzenarten, die in exponierten, ungeschützten Positionen an Felsen wachsen.
Die vorliegende Arbeit dokumentiert die Existenz folgender Assoziationen in Hessen mittels Vegetationstabellen: Potentillo anserinae-Festucetum arundinaceae, Chaerophylletum bulbosi, Stellario uliginosae-Scirpetum setacei und Chenopodietum rubri. Alle Vegetationsaufnahmen stammen aus dem Taunus. Die Dokumentation wird durch Angaben zu Häufigkeit und Standort der Assoziationen im Taunus komplettiert.
Weitere Notiz zum Erscheinungsdatum der "Flora der Gegend um Frankfurt am Main" von Johannes Becker
(2020)
Der zweite Band von Johannes Beckers "Flora der Gegend um Frankfurt am Main" (Cryptogamie) wurde offenbar zusammen mit dem ersten Teil bereits 1827 herausgegeben. Lediglich ein kleiner Teil ("Zweiter Theil. Kernschwämme") sowie wenige Seiten Nachträge zu Teil 1 wurden vor dem 5. September 1828 publiziert. Dank einer Notiz des Verlegers sowie eines Schreibens Beckers an den Senat der Stadt Frankfurt muss das Erscheinungsdatum dieser Teile nunmehr vorverlegt werden.
Die Bestände des in Deutschland stark gefährdeten Sand-Zwerggrases Mibora minima, für deren Erhalt das Land Hessen eine besondere Verantwortung trägt, gehen seit vielen Jahren zurück. In dieser Arbeit wurden als Beitrag zum Artenhilfsprogramm der Botanischen Vereinigung für Naturschutz in Hessen (BVNH) die noch vorhandenen Populationen erfasst sowie die botanischen und edaphischen Gegebenheiten an den Standorten untersucht. Dabei wurde durch Vergleich von Flächen mit und ohne Bewuchs des Zwerggrases der Frage nachgegangen, ob und inwieweit die Verbreitung der Art durch die Beschaffenheit und Nährstoffversorgung des Bodens bestimmt wird. Es wurde ein weiterer deutlicher Rückgang der südhessischen Populationen um etwa 60 % seit 1999 festgestellt, der am stärksten die Standorte um Mörfelden-Walldorf betrifft. Dagegen haben sich die Bestände bei Rüsselsheim-Königstädten möglicherweise durch Pflegemaßnahmen stabilisiert. Ein bestimmender Einfluss edaphischer Parameter auf die Verteilung der Art innerhalb der kalkfreien Flugsande konnte nicht festgestellt werden. Der indigene floristische Status der Art wird in Frage gestellt und stattdessen ihre Einstufung als Epökophyt westmediterraner Herkunft angenommen.
Das aus dem Taunus (Hessen) bisher nur durch drei Vegetationsaufnahmen belegte Ranunculo-Alopecuretum (Molinio-Arrhenatheretea, Potentillo-Polygonetalia, Potentillion anserinae) wird durch 11 weitere Aufnahmen dokumentiert und das für Hessen (Deutschland) bisher in der Literatur nicht erwähnte seltene Alopecuretum aequalis (Bidentetea, Bidentetalia, Bidention) durch zwei Aufnahmen belegt. In dem im Taunus gelegenen FFH-Gebiet "Eichkopf bei Ober-Mörlen" wächst Alopecurus aequalis in einer Pflanzengesellschaft, die nicht der nach ihm benannten Assoziation zugeordnet werden kann, sondern zwischen der Vegetationsklasse Isoëto-Nanojuncetea und Pionierstadien der Phragmitetea vermittelt.
Im Taunus konnten folgende Pflanzengesellschaften der Ordnung Agropyretalia intermedio-repentis durch Vegetationsaufnahmen belegt werden: Convolvulo arvensis-Agropyretum repentis, Cardario drabae-Agropyretum repentis, Falcario vulgaris-Agropyretum repentis, Diplotaxio tenuifoliae-Agropyretum repentis, Agropyro repentis-Rumicetum thyrsiflori, Poo compressae-Anthemidetum tinctoriae, Poo compressae-Tussilaginetum farfarae und Poa-compressa-Poa-pratensis-[Convolvulo-Agropyrion]-Gesellschaft.
Im Rahmen einer Untersuchung der Bahnsteige und des Gleisbereichs von insgesamt 31 Bahnhöfen des Taunus und seines Vorlandes konnten insgesamt acht Geranium-Arten nachgewiesen werden. Die bei weitem häufigste Art war G. robertianum (28 Bahnhöfe), mit weitem Abstand gefolgt von G. columbinum (10). Das bisher im Taunus nur einmal nachgewiesene G. purpureum wurde immerhin an sieben Bahnhöfen gefunden. Die weiteren angetroffenen Gerania waren G. molle (6 Bahnhöfe), G. pusillum (5) sowie G. dissectum, G. pyrenaicum und G. sanguineum (je 1 Bahnhof). Bei Letzterem handelte es sich offensichtlich um einen Kulturflüchtling. Höchstwahrscheinlich sind im Untersuchungsgebiet auch spontane Hybriden von G. purpureum und G. robertianum vorhanden.
Schistosomiasis is a severe neglected tropical disease caused by trematodes and transmitted by freshwater snails. Snails are known to be highly tolerant to agricultural pesticides. However, little attention has been paid to the ecological consequences of pesticide pollution in areas endemic for schistosomiasis, where people live in close contact with non-sanitized freshwaters. In complementary laboratory and field studies on Kenyan inland areas along Lake Victoria, we show that pesticide pollution is a major driver in increasing the occurrence of host snails and thus the risk of schistosomiasis transmission. In the laboratory, snails showed higher insecticide tolerance to commonly found pesticides than associated invertebrates, in particular to the neonicotinoid Imidacloprid and the organophosphate Diazinon. In the field, we demonstrated at 48 sites that snails were present exclusively in habitats characterized by pesticide pollution and eutrophication. Our analysis revealed that insensitive snails dominated over their less tolerant competitors. The study shows for the first time that in the field, pesticide concentrations considered “safe” in environmental risk assessment have indirect effects on human health. Thus we conclude there is a need for rethinking the environmental risk of low pesticide concentrations and of integrating agricultural mitigation measures in the control of schistosomiasis.
Currently, the genus Polypedates comprises 26 species distributed in South, Southeast, and East Asia. Because of their relatively low dispersal capability and intolerance to seawater, this genus is ideal for the study of terrestrial range evolution that extends into the island archipelagos of southeastern Asia. In this study, based on data compiled for Polypedates from previous studies and partial mitochondrial and nuclear genes collected in this study, we performed systematic biogeographical analysis. We confirmed a Sundaland origin for the extant genus and showed northward dispersal into mainland Southeast Asia and Asia, which coincided with the timing of paleoclimatic change from the Oligocene to Middle Miocene. Climate fluctuations had a profound impact on species diversification within the genus Polypedates. Furthermore, the Red River did not mediate species exchange between Southeast Asia and mainland Asia until the end of the Miocene, with the sudden onset of northward dispersal in several clades independently at that time. Alternatively, the lineage of widespread insular P. leucomystax strongly supports the hypothesis of terrestrial connection between island archipelagos of Southeast Asia during the Mid-Pleistocene paleoclimate fluctuations. Our biogeographical analysis also supports the recent introduction of P. leucomystax to the Philippines and Ryukyus, as previously suggested.
We contribute to the foundations of tropical geometry with a view toward formulating tropical moduli problems, and with the moduli space of curves as our main example. We propose a moduli functor for the moduli space of curves and show that it is representable by a geometric stack over the category of rational polyhedral cones. In this framework, the natural forgetful morphisms between moduli spaces of curves with marked points function as universal curves.
Our approach to tropical geometry permits tropical moduli problems—moduli of curves or otherwise—to be extended to logarithmic schemes. We use this to construct a smooth tropicalization morphism from the moduli space of algebraic curves to the moduli space of tropical curves, and we show that this morphism commutes with all of the tautological morphisms.
2019 hat Frankfurt einen Rekord geknackt: Am 25. Juli wurde im Stadtteil Westend die Tageshöchsttemperatur von 40,2 Grad Celsius erreicht. Damit war Frankfurt der heißeste Ort Hessens seit Beginn der Wetteraufzeichnungen im Jahr 1881. Ein Superlativ, der zeigt: Der Klimawandel stellt auch die Städte vor große Herausforderungen. Gesucht werden Wege, um mit seinen Folgen zurechtzukommen.
URPOSE: Today, the majority of medical graduates in countries such as the UK, the US or Germany are female. This poses a major problem for workforce planning especially in urology. We here use first the first time the previously established Brüggmann Groneberg (BG) index to assess if female academic career options advance in urology.
METHODS: Different operating parameters (student population, urology specialist population, urology chair female:male (f:m) ratio) were collected from the Federal Office of Statistics, the Federal Chamber of Physicians and the medical faculties of 36 German universities. Four time points were monitored (2000, 2005, 2010 and 2015). From these data, female to male (f:m) ratios and the recently established career advancement (BG) index have been calculated.
RESULTS: The German hospital urology specialists' f:m ratios were 0.257 (499 female vs. 1944 male) for 2015, 0.195 for 2010, 0.133 for 2005 and 0.12 for 2000. The career advancement (BG) index was 0.0007 for 2000, 0,0005 for 2005, 0.094 for 2010 and 0.073 for 2015. The decrease from 2010 to 2015 was due to an increase in the f:m ratio of hospital urologists and female medical students.
CONCLUSION: The BG index clearly illustrated that there is an urgent need for special academic career funding programs to counteract gender problems in urology. The BG index has been shown to be an excellent tool to assess female academic career options and will be very helpful to assess and document positive or negative changes in the next decades.
Was man schon weiß, gibt jedem die Stärke, weiter zu lernen und höhere Erfolgsziele zu erreichen. Im Tertiärsprachenunterricht ergreift der Lerner im Kontext Deutsch als Fremdsprache nach Englisch (DaFnE) günstige Lerngelegenheiten aus der ersten Fremdsprache Englisch. Durch die Sensibilisierung des Sprachvergleichs und der Bewusstmachung von Sprachlernerfahrungen, können Lernende mit ihren vorhandenen Sprachkenntnissen sichere Lernerfolge im DaF-Unterricht erzielen. Um den Input der Lernenden aus dem Englischen bewusst zu aktivieren, müssen optimale Lernsituationen bereitgestellt werden. In diesem Zusammenhang soll im Tertiärsprachenunterricht ein interkultureller Raum geschaffen werden, wo die Gemeinsamkeiten und Unterschiede zwischen dem Englischen und Deutschen bearbeitet werden können. Die Redewendungen können als soziokulturelle Kompetenz zu der Integrierung in den DaFnE-Unterricht bedeutend sein. Diese Arbeit konzentriert sich auf die Einbeziehung der Redewendungen in den Tertiärsprachenunterricht. Die englischen und deutschen Redewendungen wurden für den DaFnE-Unterricht analysiert und als Redewendungen mit absoluter Ähnlichkeit, Redewendungen mit teilweiser Ähnlichkeit und Redewendungen mit kontextueller Ähnlichkeit kategorisiert. Nach der Bestimmung der Redewendungen für den Tertiärsprachenunterricht DaFnE, war es wichtig, wie man diese Redewendungen als DaF-Lehrkraft im Tertiärsprachenunterricht in die Praxis umsetzen kann. Dazu wurden einige Einbeziehungswege mit Beispielen vorgeschlagen. Die Visualisierung der Redewendungen kann die Lehrkraft besonders beim Anfangsniveau effektiv einsetzen und damit einen wichtigen Antrieb zur Erweiterung des Wortschatzes geben. Die anderen zwei Einbeziehungsmöglichkeiten auf der Spur der Redewendungen und Kontextsituationen der Redewendungen können in weiteren Niveaus eingesetzt werden, nachdem sich die Lernenden an die Redewendungen gewöhnt haben. Mit dem interkulturellen Vergleich der Redewendungen können Lernmotivation, Sprachbewusstheit und zugleich Lernerautonomie gefördert werden.
O artigo traz um estudo das vanguardas, tais como elas foram apresentadas ao leitor brasileiro por algumas das primeiras histórias da literatura alemã escritas em língua portuguesa. Três histórias brasileiras da literatura alemã (KOHNEN, 1948; CARPEAUX, 1967; ROSENFELD, 1993) são confrontadas com definições teóricas e textos historiográficos mais recentes, levando-se em consideração tópicos referentes às vanguardas, como origens, período de vigência, características inerentes e autores relevantes. De 1948 até cerca de 1970, período em que as três histórias foram escritas, percebe-se um crescimento na valorização das vanguardas e uma maior complexidade em sua apresentação. O fato pode ser atribuído a um desenvolvimento dos estudos de língua e literatura alemã no Brasil da década de 1960, bem como à formação mais ampla dos historiadores, que é visível em suas produções e biografias.
Au Tchad, à cause de ses retombées financières une attention particulière est prêtée aux arbres à karité (Vitella- ria paradoxa C.F.Gaertn.). Cependant, cette culture est menacée par les plantes vasculaires parasites de la famille des Lo- ranthaceae. La présente étude a été effectuée dans 3 sites dans la région du Mandoul pour évaluer l’ampleur des attaques de Loranthaceae (gui africain) sur des arbres en fonction des classes de circonférence du tronc à 1,5 cm du sol. Elle a consisté à dénombrer sur une de surface, les arbres à karité infestés et les touffes de parasites rencontrées sur ces arbres, afin de dé- terminer leur taux et leur intensité d’infestation. Les résultats obtenus montrent que Tapinanthus dodoneifolus (DC) Danser a été trouvée comme la seule espèce de Loranthaceae qui parasite les arbres karité étudiés dans la zone d’étude. Le taux moyen d’infestation estimé à 73% augmente avec l’âge des arbres karité. La moyenne d’intensité de l’infestation/arbre (2,75 touffes à Békôh, 2,27 à Yomi and 2,04 à Bébopen) montre que Tapinanthus dodoneifolus constitue une réelle menace pour les peu- plements de karité dans la zone d’étude. Il reste à rechercher le seuil d’infestation qui provoque une réduction significative de la fructification. Pour l’instant, bien que pénible à cause de la hauteur des arbres adultes, la lutte mécanique contre les Ta- pinanthus par la coupe systématique des branches infestées est urgente dans les parcs à karité dans cette zone d’étude.
We study D and DS mesons at finite temperature using an effective field theory based on chiral and heavy-quark spin-flavor symmetries within the imaginary-time formalism. Interactions with the light degrees of freedom are unitarized via a Bethe-Salpeter approach, and the D and self-energies are calculated self-consistently. We generate dynamically the e D∗0(2300)and Ds(2317)state, and study their possible identification as the chiral We study Dand Dsmesons at finite temperature using an effective field theory based on chiral and heavy-quark spin-flavor symmetries within the imaginary-time formalism. Interactions with the light degrees of freedom are unitarized via a Bethe-Salpeter approach, and the Dand Dsself-energies are calculated self-consistently. We generate dynamically the D∗0(2300)and Ds(2317)states, and study their possible identification as the chiral partners of the Dand Dsground states, respectively. We show the evolution of their masses and decay widths as functions of temperature, and provide an analysis of the chiral-symmetry restoration in the heavy-flavor sector below the transition temperature. In particular, we analyse the very special case of the D-meson, for which the chiral partner is associated to the double-pole structure of the D∗0(2300).
A strong decline and thinning of the Arctic sea-ice cover over the past five decades has been documented. The former multiyear sea-ice system has largely changed to an annual system and with it the dynamics of sea-ice transport across the Arctic Ocean. Less sea ice is reaching the Fram Strait and more ice and ice-transported material is released in the northern Laptev Sea and the central Arctic Ocean. This trend is expected to have a decisive impact on ice associated (“sympagic”) communities. As sympagic fauna plays an important role in transmitting carbon from the ice-water interface to the pelagic and benthic food webs, it is important to monitor its community composition under the changing environmental conditions. We investigated the taxonomic composition, abundance and distribution of sea-ice meiofauna (here heterotrophs >10 μm; eight stations) and under-ice fauna (here metazoans >300 μm; fourteen stations) in Arctic 1.5 year-old pack ice north of Svalbard. Sampling was conducted during spring 2015 by sea-ice coring and trawling with a Surface and Under-Ice Trawl. We identified 42 taxa associated with the sea ice. The total abundance of sea-ice meiofauna ranged between 580 and 17,156 ind.m–2 and was dominated by Ciliophora (46%), Copepoda nauplii (29%), and Harpacticoida (20%). In contrast to earlier studies in this region, we found no Nematoda and few flatworms in our sea-ice samples. Under-ice fauna abundance ranged between 15 and 6,785 ind.m–2 and was dominated by Appendicularia (58%), caused by exceptionally high abundance at one station. Copepoda nauplii (23%), Calanus finmarchicus (9%), and Calanus glacialis (6%) were also very abundant while sympagic Amphipoda were comparatively rare (0.35%). Both sympagic communities showed regional differences in community composition and abundance between shelf and offshore stations, but only for the under-ice fauna those differences were statistically significant. Selected environmental variables moderately explained variations in abundances of both faunas. The results of this study are consistent with predictions of diversity shifts in the new Arctic.
Precipitation extremes with devastating socioeconomic consequences within the South American Monsoon System (SAMS) are expected to become more frequent in the near future. The complexity in SAMS behavior, however, poses severe challenges for reliable future projections. Thus, robust paleomonsoon records are needed to constrain the high spatiotemporal variability in the response of SAMS rainfall to different climatic drivers. This study uses Ti/Ca ratios from X‐ray fluorescence scanning of a sediment core retrieved off eastern Brazilian to trace precipitation changes over the past 322 Kyr. The results indicate that despite the spatiotemporal complexity of the SAMS, insolation forcing is the primary pacemaker of variations in the monsoonal system. Additional modulation by atmospheric pCO2 suggests that SAMS intensity over eastern Brazil will be suppressed by rising CO2 emissions in the future. Lastly, our record reveals an unprecedented strong and persistent wet period during Marine Isotope Stage 6 driven by anomalously strong trade winds.
The oomycete genus Ectrogella currently comprises a rather heterogeneous group of obligate endoparasitoids, mostly of diatoms and algae. Despite their widespread occurrence, little is known regarding the phylogenetic affinities of these bizarre organisms. Traditionally, the genus was included within the Saprolegniales, based on zoospore diplanetism and a saprolegnia/achlya-like zoospore discharge. The genus has undergone multiple re-definitions in the past, and has often been used largely indiscriminately for oomycetes forming sausage-like thalli in diatoms. While the phylogenetic affinity of the polyphyletic genus Olpidiopsis has recently been partially resolved, taxonomic placement of the genus Ectrogella remained unresolved, as no sequence data were available for species of this genus. In this study, we report the phylogenetic placement of Ectrogella bacillariacearum infecting the freshwater diatom Nitzschia sigmoidea. The phylogenetic reconstruction shows that Ectrogella bacillariacearum is grouped among the early diverging lineages of the Saprolegniomycetes with high support, and is unrelated to the monophyletic diatom-infecting olpidiopsis-like species. As these species are neither related to Ectrogella, nor to the early diverging lineages of Olpidiopsis s. str. and Miracula, they are placed in a new genus, Diatomophthora, in the present study.
In the absence of an active prophylactic vaccine against HIV-1, passively administered, broadly neutralizing antibodies (bnAbs) identified in some chronically infected persons were shown to prevent HIV-1 infection in animal models. However, passive administration of bnAbs may not be suited to prevent sexual HIV-1 transmission in high-risk cohorts, as a continuous high level of active bnAbs may be difficult to achieve at the primary site of sexual transmission, the human vagina with its acidic pH. Therefore, we used Lactobacillus, a natural commensal in the healthy vaginal microbiome, to express bn nanobodies (VHH) against HIV-1 that we reported previously. After demonstrating that recombinant VHHA6 expressed in E. coli was able to protect humanized mice from mucosal infection by HIV-1Bal, we expressed VHHA6 in a soluble or in a cell-wall-anchored form in Lactobacillus rhamnosus DSM14870. This strain is already clinically applied for treatment of bacterial vaginosis. Both forms of VHHA6 neutralized a set of primary epidemiologically relevant HIV-1 strains in vitro. Furthermore, VHHA6 was still active at an acidic pH. Thus, lactobacilli expressing bn VHH potentially represent an attractive vector for the passive immunization of women in cohorts at high risk of HIV-1 transmission.
In the course of a growing start-up market and strongly increasing investment volume, investors try to predict the success of a business as precisely as possible in advance. However, when assessing the personality of the founder or founding team, they still rely far too often on their gut feeling, thereby reducing the quality of their decisions. Our study therefore aimed at investigating whether there are any relationships between the founders' personality traits and their performance and thus justifying the need for more targeted and optimized diagnostics in the field of founder personality. With a total of 141 founders, clear correlations between personality traits (conscientiousness, emotional stability) and performance could be demonstrated in the present study. In addition, it became evident that perceived stress is also related to the founders’ personality (emotional stability negative, conscientiousness positive) and in turn has a negative effect on performance. Our findings contribute to raising awareness of the importance of personality as a predictor of founders' performance, improving decision-making, and, in the long run, replacing gut feeling as an inappropriate assessment criterion of investors.
Les données de l’effet d’affaiblissement de l’obviation (ou encore référence disjointe du subjonctif) dans la littérature linguistique sont soit fondées sur l’intuition des auteurs soit issues de publications d’autres chercheurs, bien que cet effet soit connu depuis longtemps et bien qu’il fasse partie de plusieurs modélisations théoriques. En conséquence, aucune réponse de nature empirique/expérimentale a été offerte à la question « A quel point les affirmations portant sur l'effet d'affaiblissement de l'obviation sont-elles solides ? ». Cet article se fixe en conséquence un double objectif : (i) mettre en oeuvre un jugement de grammaticalité afin de répondre expérimentalement à la question précédente, et (ii) proposer une analyse syntaxique provisoire des résultats obtenus. Ici, nous étudions six facteurs qui – selon Ruwet (1984/1991) – déclenchent l’affaiblissement. Les résultats montrent que seul un facteur (la coordination) déclenche l’affaiblissement. En conséquence, l’appareil théorique permettant de modéliser l’affaiblissement peut être réduit radicalement, et nous proposons des pistes de modélisation syntaxique n’intégrant que le facteur de coordination
The aim of this observational study was to follow-up patients with bedtime basal insulin (NPH insulin) added to metformin. In 285 patients with type 2 diabetes, a therapy with bedtime basal insulin added to metformin was started due to failure to achieve a glycaemic goal. Up until July 2019, 272 patients (95.4%) were followed-up (59.5 y, 92.6 kg, diabetes duration 6.6 y, HbA1c 8.4%/68.6 mmol/mol). HbA1c decreased by −1.2% and bodyweight by −1.7 kg after a duration of 31.7 ± 29.1 (range 2–133) months. Severe hypoglycaemia did not occur. In 144/272 patients (52.9%), the therapeutic goal for HbA1c was achieved over 32.7 months. In 69/272 patients (25.4%), the HbA1c target was achieved over 25.0 months (afterwards, therapy with basal insulin was discontinued because HbA1c was under target). In 36/272 patients (13.2%), the HbA1c goal was achieved until the submission of this manuscript (mean duration of treatment 57.4 ± 28.2 (range 13–121) months). Over 90% of patients with type 2 diabetes and failure of metformin reached their HbA1c goal with additional basal insulin at bedtime over several years in association with a reduction of bodyweight and without any event of severe hypoglycaemia.
In the present article we argue that all communication is medial in the sense that every human sign-based interaction is shaped by medial aspects from the outset. We propose a dynamic, semiotic concept of media that focuses on the process-related aspect of mediality, and we test the applicability of this concept using as an example the second presidential debate between Clinton and Trump in 2016. The analysis shows in detail how the sign processing during the debate is continuously shaped by structural aspects of television and specific traits of political communication in television. This includes how the camerawork creates meaning and how the protagonists both use the affordances of this special mediality. Therefore, it is not adequate in our view to separate the technical aspects of the medium, the ‘hardware’, from the processual aspects and the structural conditions of communication. While some aspects of the interaction are directly constituted by the medium, others are more indirectly shaped and influenced by it, especially by its institutional dimension – we understand them as second-order media effects. The whole medial procedure with its specific mediality is a necessary, but not a sufficient condition of meaning-making. We distinguish the medial procedure from the semiotic modes employed, the language games played and the competence of the players involved.
Rethinking superdeterminism
(2020)
Quantum mechanics has irked physicists ever since its conception more than 100 years ago. While some of the misgivings, such as it being unintuitive, are merely aesthetic, quantum mechanics has one serious shortcoming: it lacks a physical description of the measurement process. This “measurement problem” indicates that quantum mechanics is at least an incomplete theory—good as far as it goes, but missing a piece—or, more radically, is in need of complete overhaul. Here we describe an approach which may provide this sought-for completion or replacement: Superdeterminism. A superdeterministic theory is one which violates the assumption of Statistical Independence (that distributions of hidden variables are independent of measurement settings). Intuition suggests that Statistical Independence is an essential ingredient of any theory of science (never mind physics), and for this reason Superdeterminism is typically discarded swiftly in any discussion of quantum foundations. The purpose of this paper is to explain why the existing objections to Superdeterminism are based on experience with classical physics and linear systems, but that this experience misleads us. Superdeterminism is a promising approach not only to solve the measurement problem, but also to understand the apparent non-locality of quantum physics. Most importantly, we will discuss how it may be possible to test this hypothesis in an (almost) model independent way.
Vegetation responds to drought through a complex interplay of plant hydraulic mechanisms, posing challenges for model development and parameterization. We present a mathematical model that describes the dynamics of leaf water-potential over time while considering different strategies by which plant species regulate their water-potentials. The model has two parameters: the parameter λ describing the adjustment of the leaf water potential to changes in soil water potential, and the parameter Δψww describing the typical ‘well-watered’ leaf water potentials at non-stressed (near-zero) levels of soil water potential. Our model was tested and calibrated on 110 time-series datasets containing the leaf- and soil water potentials of 66 species under drought and non-drought conditions. Our model successfully reproduces the measured leaf water potentials over time based on three different regulation strategies under drought. We found that three parameter sets derived from the measurement data reproduced the dynamics of 53% of an drought dataset, and 52% of a control dataset [root mean square error (RMSE) < 0.5 MPa)]. We conclude that, instead of quantifying water-potential-regulation of different plant species by complex modeling approaches, a small set of parameters may be sufficient to describe the water potential regulation behavior for large-scale modeling. Thus, our approach paves the way for a parsimonious representation of the full spectrum of plant hydraulic responses to drought in dynamic vegetation models.
