Dies spiegelt sich auch in den medial ausgetragenen Debatten um Anti-Corona-Vakzine wider, in denen bestimmtes, teils konflikthaftes Wissen produziert und vermittelt wurde. Die vorliegende Masterarbeit rekonstruiert den deutschsprachigen Diskurs um die Corona-Schutzimpfung in Form einer wissenssoziologischen Diskursanalyse. Sie untersucht, wie gesellschaftliches Wissen zur Impfung in meinungsf{\"u}hrenden Tages- und Wochenzeitungen sowie in ausgew{\"a}hlten Blogs w{\"a}hrend der Pandemie von Anfang 2020 bis Mitte 2022 (re)produziert wird. Ausgangspunkt sind - ankn{\"u}pfend an aktuelle Beitr{\"a}ge der kritischen Soziologie - die politisch-{\"o}konomischen Zusammenh{\"a}nge und Voraussetzungen, wie beispielsweise globale Lebens-, Wirtschafts- und Konsumweisen, durch die diese Pandemie erst m{\"o}glich wurde. Durch diese Perspektive kann die Pandemie als soziales Ereignis begriffen werden, anstatt als unvorhersehbare medizinische Katastrophe, wie es in den politischen und medialen Debatten den Anschein hatte. In der Analyse zeigt sich, dass diese Umst{\"a}nde in der medialen Auseinandersetzung keinerlei Widerhall fanden, was den Diskurs de-kontextualisiert und den herausgearbeiteten Radikalismen den Boden bereitet hat. Die Analyse erm{\"o}glicht es, zwei Zug{\"a}nge zum Diskurs zu unterscheiden: Ein Portal er{\"o}ffnet den Zugang {\"u}ber gesellschaftlich mehrheitlich anerkanntes, also orthodoxes Wissen, das zweite {\"u}ber gesellschaftlich mehrheitlich nicht anerkanntes, also heterodoxes Wissen. Entlang von benannten Themen, Problemen und L{\"o}sungen lassen sich auf einer Pro-Kontra-Achse sieben Wissenstypen rekonstruieren, die von radikaler Impfbef{\"u}rwortung bis radikaler Ablehnung reichen. Vier der Wissensbest{\"a}nde argumentieren f{\"u}r die Impfung, drei dagegen - der Raum des Indifferenten dazwischen bleibt medial unbesetzt. Anschließend werden diese Typen entlang von Werten, auf die rekurriert wird, und schließlich nach Ressourcen, Verantwortlichkeiten und Sprecher*innenrollen unterschieden, sodass eine klare und idealtypische Charakterisierung des jeweiligen Wissens entsteht. Durch die Analyse werden {\"u}berdies diskursive Verschiebungen im Zeitverlauf sichtbar. Es zeigen sich einerseits eine Polarisierung des Diskurses insgesamt, andererseits eine Ern{\"u}chterung innerhalb der Impfbef{\"u}rwortung sowie die interdependente Radikalisierung von Positionen an beiden Enden des Spektrums. Abschließend werden die Ergebnisse der Analyse komplement{\"a}r zum Ausgangspunkt gesellschaftstheoretisch eingebettet. Zum einen werden Eigendynamiken de-kontextualisierter und sich infolgedessen radikalisierender Diskurse reflektiert, innerhalb derer sich die Extreme so weit voneinander entfernen, dass sie sich schlussendlich wieder ber{\"u}hren. Zum anderen wird die im Diskurs sichtbar dominante neo-soziale Anrufung der individuellen Verantwortung in einer gleichzeitig wenig solidarischen Gesellschaft im Kontext eines neoliberal gepr{\"a}gten Verst{\"a}ndnisses von individueller Freiheit, Demokratie und sozialer Verantwortung diskutiert.}, language = {de} } @misc{Eckler2011, author = {Eckler, Susanne}, title = {Didaktisch-methodische Zug{\"a}nge zum Themenfeld 'Nationalsozialismus' aus konstruktivistischer Perspektive}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-57684}, year = {2011}, abstract = {Die Arbeit gibt einen kurzen Abriss {\"u}ber die Grundlagen systemisch-konstruktivistischer Lerntheorie mit der anschließenden Fragestellung, was die aktuellen Forschungsergebnisse aus Neurobiologie, Philosophie, Psychologie und Erziehungswissenschaften zur didaktischen Auseinandersetzung mit dem Nationalsozialismus beitragen k{\"o}nnen.

Solidago canadensis showed latitudinal clines in flowering phenology and growth. In S. gigantea, the number of clonal offspring decreased with latitude.

A previous common-garden experiment showed heritable latitudinal clines in fitness-related traits in the invasive goldenrod Solidago canadensis in Central Europe. These latitudinal clines remained stable even in plants chemically treated with zebularine to reduce epigenetic variation. However, despite the heritability of traits investigated, genetic isolation-by-distance was non-significant. Utilizing the same specimens, we applied a molecular analysis of (epi)genetic differentiation with standard and methylation-sensitive (MSAP) AFLPs. We tested whether this variation was spatially structured among populations and whether zebularine had altered epigenetic variation. Additionally, we used genome scans to mine for putative outlier loci susceptible to selection processes in the invaded range. Despite the absence of isolation-by-distance, we found spatial genetic neighborhoods among populations and two AFLP clusters differentiating northern and southern Solidago populations. Genetic and epigenetic diversity were significantly correlated, but not linked to phenotypic variation. Hence, no spatial epigenetic patterns were detected along the latitudinal gradient sampled. Applying genome-scan approaches (BAYESCAN, BAYESCENV, RDA, and LFMM), we found 51 genetic and epigenetic loci putatively responding to selection. One of these genetic loci was significantly more frequent in populations at the northern range. Also, one epigenetic locus was more frequent in populations in the southern range, but this pattern was lost under zebularine treatment.

However, the basis of successful plant invasion is not conclusively understood, especially since these plant species can adapt to the new range within a short period of time despite impoverished genetic diversity of the starting populations. In this context, DNA methylation is considered promising to explain successful adaptation mechanisms in the new habitat. DNA methylation is a heritable variation in gene expression without changing the underlying genetic information. Thus, DNA methylation is considered a so-called epigenetic mechanism, but has been studied in mainly clonally reproducing plant species or genetic model plants. An understanding of this epigenetic mechanism in the context of non-native, predominantly sexually reproducing plant species might help to expand knowledge in biodiversity research on the interaction between plants and their habitats and, based on this, may enable more precise measures in conservation biology. For my studies, I combined chemical DNA demethylation of field-collected seed material from predominantly sexually reproducing species and rearing offsping under common climatic conditions to examine DNA methylation in an ecological-evolutionary context. The contrast of chemically treated (demethylated) plants, whose variation in DNA methylation was artificially reduced, and untreated control plants of the same species allowed me to study the impact of this mechanism on adaptive trait differentiation and local adaptation. With this experimental background, I conducted three studies examining the effect of DNA methylation in non-native species along a climatic gradient and also between climatically divergent regions. The first study focused on adaptive trait differentiation in two invasive perennial goldenrod species, Solidago canadensis sensu latu and S. gigantea AITON, along a climate gradient of more than 1000 km in length in Central Europe. I found population differences in flowering timing, plant height, and biomass in the temporally longer-established S. canadensis, but only in the number of regrowing shoots for S. gigantea. While S. canadensis did not show any population structure, I was able to identify three genetic groups along this climatic gradient in S. gigantea. Surprisingly, demethylated plants of both species showed no change in the majority of traits studied. In the subsequent second study, I focused on the longer-established goldenrod species S. canadensis and used molecular analyses to infer spatial epigenetic and genetic population differences in the same specimens from the previous study. I found weak genetic but no epigenetic spatial variation between populations. Additionally, I was able to identify one genetic marker and one epigenetic marker putatively susceptible to selection. However, the results of this study reconfirmed that the epigenetic mechanism of DNA methylation appears to be hardly involved in adaptive processes within the new range in S. canadensis. Finally, I conducted a third study in which I reciprocally transplanted short-lived plant species between two climatically divergent regions in Germany to investigate local adaptation at the plant family level. For this purpose, I used four plant families (Amaranthaceae, Asteraceae, Plantaginaceae, Solanaceae) and here I additionally compared between non-native and native plant species. Seeds were transplanted to regions with a distance of more than 600 kilometers and had either a temperate-oceanic or a temperate-continental climate. In this study, some species were found to be maladapted to their own local conditions, both in non-native and native plant species alike. In demethylated individuals of the plant species studied, DNA methylation had inconsistent but species-specific effects on survival and biomass production. The results of this study highlight that DNA methylation did not make a substantial contribution to local adaptation in the non-native as well as native species studied. In summary, my work showed that DNA methylation plays a negligible role in both adaptive trait variation along climatic gradients and local adaptation in non-native plant species that either exhibit a high degree of genetic variation or rely mainly on sexual reproduction with low clonal propagation. I was able to show that the adaptive success of these non-native plant species can hardly be explained by DNA methylation, but could be a possible consequence of multiple introductions, dispersal corridors and meta-population dynamics. Similarly, my results illustrate that the use of plant species that do not predominantly reproduce clonally and are not model plants is essential to characterize the effect size of epigenetic mechanisms in an ecological-evolutionary context.}, language = {en} } @misc{EckertNorellMiedemaetal.2017, author = {Eckert, Sebastian and Norell, Jesper and Miedema, Piter S. and Beye, Martin and Fondell, Mattis and Quevedo, Wilson and Kennedy, Brian and Hantschmann, Markus and Pietzsch, Annette and van Kuiken, Benjamin E. and Ross, Matthew and Minitti, Michael P. and Moeller, Stefan P. and Schlotter, William F. and Khalil, Munira and Odelius, Michael and F{\"o}hlisch, Alexander}, title = {Untersuchung unabh{\"a}ngiger N-H- und N-C-Bindungsverformungen auf ultrakurzen Zeitskalen mit resonanter inelastischer R{\"o}ntgenstreuung}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, number = {1121}, issn = {1866-8372}, doi = {10.25932/publishup-43668}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-436688}, pages = {7}, year = {2017}, abstract = {Die Femtosekundendynamik nach resonanten Photoanregungen mit optischen und R{\"o}ntgenpulsen erm{\"o}glicht eine selektive Verformung von chemischen N-H- und N-C-Bindungen in 2-Thiopyridon in w{\"a}ssriger L{\"o}sung.
