Die erste deutsche Homer-Übersetzung zeugt nicht nur von der typisch humanistischen Wertschätzung antiker Autoren, sondern stellt einen genuinen Beitrag zur Entwicklung frühneuzeitlicher Poetologie dar. Durch die Verwendung rhetorischer und metrischer Mittel sowie durch die logische Begründung kausaler und temporaler Zusammenhänge setzt Simon Schaidenreisser eigene Akzente, die die deutsche Odyssee von der lateinischen Vorlage und dem griechischen Prätext unterscheiden. Das in der Vorrede angegebene Ziel seiner Übersetzung, die deutsche Sprache und Literatur zu bereichern, hat Schaidenreisser zweifellos erreicht.
Im Artikel wird ein binationales Internet-Projekt beschrieben. Daran nahmen ein Deutschkurs der Universität Alcalá de Henares in Spanien und zwei Spanischkurse der Universität Würzburg teil. Diese tauschten sich über einen Web-Blog aus. Das Ziel war, die jeweilige Stadt vorzustellen und so der anderen Seite einen virtuellen Besuch im Land der Zielsprache zu ermöglichen. Der Artikel beschreibt den didaktischen Umgang mit dem Blog und gibt Hinweise für Lehrende, die einen Blog im Unterricht einsetzen möchten.
Abstract: Inbreeding depression, asymmetries in costs or benefits of dispersal, and the mating system have been identified as potential factors underlying the evolution of sex-biased dispersal. We use individual-based simulations to explore how the mating system and demographic stochasticity influence the evolution of sex-specific dispersal in a metapopulation with females competing over breeding sites, and males over mating opportunities. Comparison of simulation results for random mating with those for a harem system (locally, a single male sires all offspring) reveal that even extreme variance in local male reproductive success (extreme male competition) does not induce male-biased dispersal. The latter evolves if the between-parch variance in reproductive success is larger for males than females. This can emerge due to demographic stochasticity if the habitat patches are small. More generally, members of a group of individuals experiencing higher spatio-temporal variance in fitness expectations may evolve to disperse with greater probability than others.
Background: Male killing endosymbionts manipulate their arthropod host reproduction by only allowing female embryos to develop into infected females and killing all male offspring. Because the resulting change in sex ratio is expected to affect the evolution of sex-specific dispersal, we investigated under which environmental conditions strong sex-biased dispersal would emerge, and how this would affect host and endosymbiont metapopulation persistence. Results: We simulated host-endosymbiont metapopulation dynamics in an individual-based model, in which dispersal rates are allowed to evolve independently for the two sexes. Prominent male-biased dispersal emerges under conditions of low environmental stochasticity and high dispersal mortality. By applying a reshuffling algorithm, we show that kin-competition is a major driver of this evolutionary pattern because of the high within-population relatedness of males compared to those of females. Moreover, the evolution of sex-specific dispersal rescues metapopulations from extinction by (i) reducing endosymbiont fixation rates and (ii) by enhancing the extinction of endosymbionts within metapopulations that are characterized by low environmental stochasticity. Conclusion: Male killing endosymbionts induce the evolution of sex-specific dispersal, with prominent male-biased dispersal under conditions of low environmental stochasticity and high dispersal mortality. This male-biased dispersal emerges from stronger kin-competition in males compared to females and induces an evolutionary rescue mechanism.
Abstract: 1. The response of dispersal towards evolution largely depends on its heritability for which upper limits are determined by the trait's repeatability. 2. In the Linyphiid spider E. atra, we were able to separate long- and short-distance dispersal behaviours (respectively ballooning and rappelling) under laboratory conditions. By performing repeated behavioural trials for females, we show that average dispersal trait values decrease with increasing testing days. By comparing mated and unmated individuals during two periods (before and after mating for the mated group, and the same two periods for the unmated group), we show that mating has no effect on the mean displayed dispersal behaviour or its within-individual variation. Repeatabilities were high and consistent for ballooning motivation, but not for rappelling. 3. Ballooning motivation can be regarded as highly individual-specific behaviour, while general pre-dispersal and rappelling behaviours showed more individual variation. Such difference in repeatability between long-and short-distance dispersal suggests that short-and long-distance dispersal events are triggered by different ecological and evolutionary mechanisms.
DaF-Unterricht an Hochschulen hat zum Ziel, nicht-deutschen Studierenden möglichst zügig die deutsche Sprache zu vermitteln. Da sie sich bereits im Zielsprachenland aufhalten und hier (für begrenzte Zeit) leben, ist es wichtig, auch landeskundliche Kenntnisse zu erwerben. Beides geschieht im universitären Sprachunterricht aufgrund von äußeren Rahmenbedingungen oft sehr "kopflastig". Projektorientierte Methoden können hier Abhilfe schaffen, da jeder einzelne Lernerde sehr viel intensiver selbst aktiv werden muss als im herkömmlichen Sprachunterricht. Besonders gewinnbringend werden Projekte, wenn sie in Kooperation mit deutschen Muttersprachlern, am besten künftigen DeutschlehrerInnen stattfinden. Diese sind nicht nur authentische Gesprächspartner, sondern haben zudem auch (in unterschiedlich ausgeprägtem Maße) didaktische Kenntnisse, die in die Projektarbeit einfließen. Sie selbst können in solchen Kooperationen wichtige Erfahrungen für ihren Lehrberuf sammeln. Wie dies in der Praxis aussehen kann, soll in diesem Beitrag exemplarisch vorgestellt werden.
Background
Suicide and non-fatal suicidal behaviour are significant public health issues in Europe requiring effective preventive interventions. However, the evidence for effective preventive strategies is scarce. The protocol of a European research project to develop an optimized evidence based program for suicide prevention is presented.
Method
The groundwork for this research has been established by a regional community based intervention for suicide prevention that focuses on improving awareness and care for depression performed within the European Alliance Against Depression (EAAD). The EAAD intervention consists of (1) training sessions and practice support for primary care physicians,(2) public relations activities and mass media campaigns, (3) training sessions for community facilitators who serve as gatekeepers for depressed and suicidal persons in the community and treatment and (4) outreach and support for high risk and self-help groups (e.g. helplines). The intervention has been shown to be effective in reducing suicidal behaviour in an earlier study, the Nuremberg Alliance Against Depression. In the context of the current research project described in this paper (OSPI-Europe) the EAAD model is enhanced by other evidence based interventions and implemented simultaneously and in standardised way in four regions in Ireland, Portugal, Hungary and Germany.
The enhanced intervention will be evaluated using a prospective controlled design with the primary outcomes being composite suicidal acts (fatal and non-fatal), and with intermediate outcomes being the effect of training programs, changes in public attitudes, guideline-consistent media reporting. In addition an analysis of the economic costs and consequences will be undertaken, while a process evaluation will monitor implementation of the interventions within the different regions with varying organisational and healthcare contexts.
Discussion
This multi-centre research seeks to overcome major challenges of field research in suicide prevention. It pools data from four European regions, considerably increasing the study sample, which will be close to one million. In addition, the study will gather important information concerning the potential to transfer this multilevel program to other health care systems. The results of this research will provide a basis for developing an evidence-based, efficient concept for suicide prevention for EU-member states.

Dieser Artikel beschreibt eine Unterrichtssequenz für den Deutschunterricht im Bereich Deutsch als Fremdsprache und richtet sich an Lernende der Niveaustufe A2. Er zeigt, wie Lernende spielerisch sowohl rezeptive Sprachkenntnisse als auch aktive Sprachbeherrschung verbessern und ihren Wortschatz erweitern können. Ein besonders wichtiges Kriterium sind dabei der Spielcharakter und die Auflockerung des Unterrichts, sowie die Möglichkeit, individuell auf die Bedürfnisse der Studenten eingehen zu können.
