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.

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.

However, some territorially breeding animals can have dramatic density fluctuations and little is known about the change from density-dependent processes to density-independence of breeding during a population increase or an outbreak. We suggest that territoriality, breeding suppression and its break-down can be understood with an incomplete-control model, developed for social breeders and social suppression. Results We studied density dependence in an arvicoline species, the bank vole, known as a territorial breeder with cyclic and non-cyclic density fluctuations and periodically high densities in different parts of its range. Our long-term data base from 38 experimental populations in large enclosures in boreal grassland confirms that breeding rates are density-regulated at moderate densities, probably by social suppression of subordinate potential breeders. We conducted an experiment, were we doubled and tripled this moderate density under otherwise the same conditions and measured space use, mortality, reproduction and faecal stress hormone levels (FGM) of adult females. We found that mortality did not differ among the densities, but the regulation of the breeding rate broke down: at double and triple densities all females were breeding, while at the low density the breeding rate was regulated as observed before. Spatial overlap among females increased with density, while a minimum territory size was maintained. Mean stress hormone levels were higher in double and triple densities than at moderate density. Conclusions At low and moderate densities, breeding suppression by the dominant breeders, But above a density-threshold (similar to a competition point), the dominance of breeders could not be sustained (incomplete control). In our experiment, this point was reached after territories could not shrink any further, while the number of intruders continued to increase with increasing density. Probably suppression becomes too costly for the dominants, and increasing number of other breeders reduces the effectiveness of threats. In wild populations, crossing this threshold would allow for a rapid density increase or population outbreaks, enabling territorial species to escape density-dependency.}, language = {en} } @misc{EccardHerdeSchusteretal.2022, author = {Eccard, Jana and Herde, Antje and Schuster, Andrea C. and Liesenjohann, Thilo and Knopp, Tatjana and Heckel, Gerald and Dammhahn, Melanie}, title = {Fitness, risk taking, and spatial behavior covary with boldness in experimental vole populations}, series = {Zweitver{\"o}ffentlichungen der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, journal = {Zweitver{\"o}ffentlichungen der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {1866-8372}, doi = {10.25932/publishup-55886}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-558866}, pages = {1 -- 15}, year = {2022}, abstract = {Individuals of a population may vary along a pace-of-life syndrome from highly fecund, short-lived, bold, dispersive "fast" types at one end of the spectrum to less fecund, long-lived, shy, plastic "slow" types at the other end. Risk-taking behavior might mediate the underlying life history trade-off, but empirical evidence supporting this hypothesis is still ambiguous. Using experimentally created populations of common voles (Microtus arvalis)—a species with distinct seasonal life history trajectories—we aimed to test whether individual differences in boldness behavior covary with risk taking, space use, and fitness. We quantified risk taking, space use (via automated tracking), survival, and reproductive success (via genetic parentage analysis) in 8 to 14 experimental, mixed-sex populations of 113 common voles of known boldness type in large grassland enclosures over a significant part of their adult life span and two reproductive events. Populations were assorted to contain extreme boldness types (bold or shy) of both sexes. Bolder individuals took more risks than shyer ones, which did not affect survival. Bolder males but not females produced more offspring than shy conspecifics. Daily home range and core area sizes, based on 95\% and 50\% Kernel density estimates (20 ± 10 per individual, n = 54 individuals), were highly repeatable over time. Individual space use unfolded differently for sex-boldness type combinations over the course of the experiment. While day ranges decreased for shy females, they increased for bold females and all males. Space use trajectories may, hence, indicate differences in coping styles when confronted with a novel social and physical environment. Thus, interindividual differences in boldness predict risk taking under near-natural conditions and have consequences for fitness in males, which have a higher reproductive potential than females. Given extreme inter- and intra-annual fluctuations in population density in the study species and its short life span, density-dependent fluctuating selection operating differently on the sexes might maintain (co)variation in boldness, risk taking, and pace-of-life.}, language = {en} } @misc{EccardHerde2013, author = {Eccard, Jana and Herde, Antje}, title = {Seasonal variation in the behaviour of a short-lived rodent}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-401370}, pages = {9}, year = {2013}, abstract = {Background: Short lived, iteroparous animals in seasonal environments experience variable social and environmental conditions over their lifetime. Animals can be divided into those with a "young-of-the-year" life history (YY, reproducing and dying in the summer of birth) and an "overwinter" life history (OW, overwintering in a subadult state before reproducing next spring). We investigated how behavioural patterns across the population were affected by season and sex, and whether variation in behaviour reflects the variation in life history patterns of each season. Applications of pace-of-life (POL) theory would suggest that long-lived OW animals are shyer in order to increase survival, and YY are bolder in order to increase reproduction. Therefore, we expected that in winter and spring samples, when only OW can be sampled, the animals should be shyer than in summer and autumn, when both OW and YY animals can be sampled. We studied common vole (Microtus arvalis) populations, which express typical, intra-annual density fluctuation. We captured a total of 492 voles at different months over 3 years and examined boldness and activity level with two standardised behavioural experiments. Results: Behavioural variables of the two tests were correlated with each other. Boldness, measured as short latencies in both tests, was extremely high in spring compared to other seasons. Activity level was highest in spring and summer, and higher in males than in females. Conclusion: Being bold in laboratory tests may translate into higher risk-taking in nature by being more mobile while seeking out partners or valuable territories. Possible explanations include asset-protection, with OW animals being rather old with low residual reproductive value in spring. Therefore, OW may take higher risks during this season. Offspring born in spring encounter a lower population density and may have higher reproductive value than offspring of later cohorts. A constant connection between life history and animal personality, as suggested by the POL theory, however, was not found. Nevertheless, correlations of traits suggest the existence of animal personalities. In conclusion, complex patterns of population dynamics, seasonal variation in life histories, and variability of behaviour due to asset-protection may cause complex seasonal behavioural dynamics in a population.}, language = {en} } @misc{EccardFeyCaspersetal.2011, author = {Eccard, Jana and Fey, Karen and Caspers, Barbara A. and Yl{\"o}nen, Hannu}, title = {Breeding state and season affect interspecific interaction types}, series = {Postprints der Universit{\"a}t Potsdam Mathematisch-Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam Mathematisch-Naturwissenschaftliche Reihe}, number = {729}, issn = {1866-8372}, doi = {10.25932/publishup-42939}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-429398}, pages = {623 -- 633}, year = {2011}, abstract = {Indirect resource competition and interference are widely occurring mechanisms of interspecific interactions. We have studied the seasonal expression of these two interaction types within a two-species, boreal small mammal system. Seasons differ by resource availability, individual breeding state and intraspecific social system. Live-trapping methods were used to monitor space use and reproduction in 14 experimental populations of bank voles Myodes glareolus in large outdoor enclosures with and without a dominant competitor, the field vole Microtus agrestis. We further compared vole behaviour using staged dyadic encounters in neutral arenas in both seasons. Survival of the non-breeding overwintering bank voles was not affected by competition. In the spring, the numbers of male bank voles, but not of females, were reduced significantly in the competition populations. Bank vole home ranges expanded with vole density in the presence of competitors, indicating food limitation. A comparison of behaviour between seasons based on an analysis of similarity revealed an avoidance of costly aggression against opponents, independent of species. Interactions were more aggressive during the summer than during the winter, and heterospecific encounters were more aggressive than conspecific encounters. Based on these results, we suggest that interaction types and their respective mechanisms are not either-or categories and may change over the seasons. During the winter, energy constraints and thermoregulatory needs decrease direct aggression, but food constraints increase indirect resource competition. Direct interference appears in the summer, probably triggered by each individual's reproductive and hormonal state and the defence of offspring against conspecific and heterospecific intruders. Both interaction forms overlap in the spring, possibly contributing to spring declines in the numbers of subordinate species.}, language = {en} } @misc{EccardDammhahnYloenen2017, author = {Eccard, Jana and Dammhahn, Melanie and Yl{\"o}nen, Hannu}, title = {The Bruce effect revisited}, series = {Postprints der Universit{\"a}t Potsdam Mathematisch-Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam Mathematisch-Naturwissenschaftliche Reihe}, number = {734}, issn = {1866-8372}, doi = {10.25932/publishup-43295}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-432956}, pages = {14}, year = {2017}, abstract = {Pregnancy termination after encountering a strange male, the Bruce effect, is regarded as a counterstrategy of female mammals towards anticipated infanticide. While confirmed in caged rodent pairs, no verification for the Bruce effect existed from experimental field populations of small rodents. We suggest that the effect may be adaptive for breeding rodent females only under specific conditions related to populations with cyclically fluctuating densities. We investigated the occurrence of delay in birth date after experimental turnover of the breeding male under different population composition in bank voles (Myodes glareolus) in large outdoor enclosures: one-male-multiple-females (n = 6 populations/18 females), multiple-males-multiple-females (n = 15/45), and single-male-single-female (MF treatment, n = 74/74). Most delays were observed in the MF treatment after turnover. Parallel we showed in a laboratory experiment (n = 205 females) that overwintered and primiparous females, the most abundant cohort during population lows in the increase phase of cyclic rodent populations, were more likely to delay births after turnover of the male than year-born and multiparous females. Taken together, our results suggest that the Bruce effect may be an adaptive breeding strategy for rodent females in cyclic populations specifically at low densities in the increase phase, when isolated, overwintered animals associate in MF pairs. During population lows infanticide risk and inbreeding risk may then be higher than during population highs, while also the fitness value of a litter in an increasing population is higher. Therefore, the Bruce effect may be adaptive for females during annual population lows in the increase phases, even at the costs of delaying reproduction.}, language = {en} } @article{Ebseev2013, author = {Ebseev, Boris S.}, title = {Das Verfassungsgericht Russlands}, series = {Verfassungsgerichtsbarkeit in der Russischen F{\"o}deration und in der Bundesrepublik Deutschland : Rundtischgespr{\"a}ch an der Moskauer Staatlichen Juristischen Kutafin-Universit{\"a}t am 9. und 10.

The first, investigative, strategy describes metabolic networks in terms of their capability to utilize different carbon sources, resulting in the concept of carbon utilization spectra. In the second, predictive, approach minimal nutrient combinations are predicted from the structure of the metabolic networks, resulting in a characteristic nutrient profile. Both strategies allow for a quantification of functional properties of metabolic networks, allowing to identify groups of organisms with similar functions. We investigate whether the functional description reflects the typical environments of the corresponding organisms by dividing all species into disjoint groups based on whether they are aerotolerant and/or photosynthetic. Despite differences in the underlying concepts, both measures display some common features. Closely related organisms often display a similar functional behavior and in both cases the functional measures appear to correlate with the considered classes of environments. Carbon utilization spectra and nutrient profiles are complementary approaches toward a functional classification of organism-wide metabolic networks. Both approaches contain different information and thus yield different clusterings, which are both different from the classical taxonomy of organisms. Our results indicate that a sophisticated combination of our approaches will allow for a quantitative description reflecting the lifestyles of organisms.}, language = {en} } @misc{EbelBald2020, author = {Ebel, Kenny and Bald, Ilko}, title = {Length and Energy Dependence of Low-Energy Electron-Induced Strand Breaks in Poly(A) DNA}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, number = {814}, issn = {1866-8372}, doi = {10.25932/publishup-44412}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-444125}, pages = {13}, year = {2020}, abstract = {The DNA in living cells can be effectively damaged by high-energy radiation, which can lead to cell death. Through the ionization of water molecules, highly reactive secondary species such as low-energy electrons (LEEs) with the most probable energy around 10 eV are generated, which are able to induce DNA strand breaks via dissociative electron attachment. Absolute DNA strand break cross sections of specific DNA sequences can be efficiently determined using DNA origami nanostructures as platforms exposing the target sequences towards LEEs. In this paper, we systematically study the effect of the oligonucleotide length on the strand break cross section at various irradiation energies. The present work focuses on poly-adenine sequences (d(A₄), d(A₈), d(A₁₂), d(A₁₆), and d(A₂₀)) irradiated with 5.0, 7.0, 8.4, and 10 eV electrons. Independent of the DNA length, the strand break cross section shows a maximum around 7.0 eV electron energy for all investigated oligonucleotides confirming that strand breakage occurs through the initial formation of negative ion resonances. When going from d(A₄) to d(A₁₆), the strand break cross section increases with oligonucleotide length, but only at 7.0 and 8.4 eV, i.e., close to the maximum of the negative ion resonance, the increase in the strand break cross section with the length is similar to the increase of an estimated geometrical cross section. For d(A₂₀), a markedly lower DNA strand break cross section is observed for all electron energies, which is tentatively ascribed to a conformational change of the dA₂₀ sequence. The results indicate that, although there is a general length dependence of strand break cross sections, individual nucleotides do not contribute independently of the absolute strand break cross section of the whole DNA strand. The absolute quantification of sequence specific strand breaks will help develop a more accurate molecular level understanding of radiation induced DNA damage, which can then be used for optimized risk estimates in cancer radiation therapy.}, language = {en} } @phdthesis{Ebel2021, author = {Ebel, Kenny}, title = {Quantification of low-energy electron induced single and double strand breaks in well-defined DNA sequences using DNA origami nanostructures}, doi = {10.25932/publishup-50449}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-504499}, school = {Universit{\"a}t Potsdam}, pages = {111}, year = {2021}, abstract = {Ionizing radiation is used in cancer radiation therapy to effectively damage the DNA of tumors leading to cell death and reduction of the tumor tissue. The main damage is due to generation of highly reactive secondary species such as low-energy electrons (LEE) with the most probable energy around 10 eV through ionization of water molecules in the cells. A simulation of the dose distribution in the patient is required to optimize the irradiation modality in cancer radiation therapy, which must be based on the fundamental physical processes of high-energy radiation with the tissue. In the present work the accurate quantification of DNA radiation damage in the form of absolute cross sections for LEE-induced DNA strand breaks (SBs) between 5 and 20 eV is done by using the DNA origami technique. This method is based on the analysis of well-defined DNA target sequences attached to DNA origami triangles with atomic force microscopy (AFM) on the single molecule level. The present work focuses on poly-adenine sequences (5'-d(A4), 5'-d(A8), 5'-d(A12), 5'-d(A16), and 5'- d(A20)) irradiated with 5.0, 7.0, 8.4, and 10 eV electrons. Independent of the DNA length, the strand break cross section shows a maximum around 7.0 eV electron energy for all investigated oligonucleotides confirming that strand breakage occurs through the initial formation of negative ion resonances. Additionally, DNA double strand breaks from a DNA hairpin 5'-d(CAC)4T(Bt-dT)T2(GTG)4 are examined for the first time and are compared with those of DNA single strands 5'-d(CAC)4 and 5'- d(GTG)4. The irradiation is made in the most likely energy range of 5 to 20 eV with an anionic resonance maximum around 10 eV independently of the DNA sequence. There is a clear difference between σSSB and σDSB of DNA single and double strands, where the strand break for ssDNA are always higher in all electron energies compared to dsDNA by the factor 3. A further part of this work deals with the characterization and analysis of new types of radiosensitizers used in chemoradiotherapy, which selectively increases the DNA damage upon radiation. Fluorinated DNA sequences with 2'-fluoro-2'-deoxycytidine (dFC) show an increased sensitivity at 7 and 10 eV compared to the unmodified DNA sequences by an enhancement factor between 2.1 and 2.5.

A good understanding of the water cycle in these mountain regions is therefore needed to develop water management strategies. Hydrological modeling helps to improve our knowledge of the regional water cycle, and it can be used to gain a better understanding of past changes or estimate future hydrologic changes in view of projected changes in climate. However, due to the scarcity of hydrometeorological data, hydrological modeling for mountain regions in Central Asia involves large uncertainties. Addressing this problem, the first aim of this thesis was to develop hydrological modeling approaches that can increase the credibility of hydrological models in data sparse mountain regions. This was achieved by using additional data from remote sensing and atmospheric modeling. It was investigated whether spatial patterns from downscaled reanalysis data can be used for the interpolation of station-based precipitation data. This approach was compared to other precipitation estimates using a hydrologic evaluation based on hydrological modeling and a comparison of simulated and observed discharge, which demonstrated a generally good performance of this method. The study further investigated the value of satellite-derived snow cover data for model calibration. Trade-offs of good model performance in terms of discharge and snow cover were explicitly evaluated using a multiobjective optimization algorithm, and the results were contrasted with single-objective calibration and Monte Carlo simulations. The study clearly shows that the additional use of snow cover data improved the internal consistency of the hydrological model. In this context, it was further investigated for the first time how many snow cover scenes were required for hydrological model calibration. The second aim of this thesis was the application of the hydrological model in order to investigate the causes of observed streamflow increases in two headwater catchments of the Tarim River over the recent decades. This simulation-based approach for trend attribution was complemented by a data-based approach. The hydrological model was calibrated to discharge and glacier mass balance data and considered changes in glacier geometry over time. The results show that in the catchment with a lower glacierization, increasing precipitation and temperature both contributed to the streamflow increases, while in the catchment with a stronger glacierization, increasing temperatures were identified as the dominant driver.}, language = {en} } @article{DuesterhoeftTrueggelmannRichter2014, author = {D{\"u}sterh{\"o}ft, Stefanie and Tr{\"u}ggelmann, Maria and Richter, Kerstin}, title = {Vorschulische Sprachstandserhebungen in Berliner Kindertagesst{\"a}tten}, series = {Spektrum Patholinguistik}, journal = {Spektrum Patholinguistik}, number = {7}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {1866-9085}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-71505}, pages = {133 -- 138}, year = {2014}, abstract = {1 Einleitung 2 Methodik 3 Ergebnisse 4 Schlussfolgerung 5 Literatur}, language = {de} } @article{DuesterhoeftPosseTopajetal.2016, author = {D{\"u}sterh{\"o}ft, Stefanie and Posse, Dorothea and Topaj, Nathalie and Golcher, Felix and Gagarina, Natalʹja Vladimirovna}, title = {Der Einfluss von Sprachf{\"o}rdermaßnahmen auf das Sprachverst{\"a}ndnis bilingualer Kinder}, series = {Spektrum Patholinguistik Band 9.

To account for the effects of sedimentation rate changes on the spectral expression of the orbital cycles we developed a new method: the Multi-band Wavelet Age modeling technique (MUBAWA). By using a Continuous Wavelet Transformation, we were able to track frequency shifts that resulted from changing sedimentation rates and thus calculated tuned age model encompassing the last 620 kyrs. The results show a good agreement with the directly dated age model that is available from the dating of volcanic ashes. Then we used the XRF data from CHB and developed a new and robust humid-arid index of east African climate during the last 620 kyrs. To disentangle the relationship of the selected elements we performed a principal component analysis (PCA). In a following step we applied a continuous wavelet transformation on the PC1, using the directly dated age model. The resulting wavelet power spectrum, unlike a normal power spectrum, displays the occurrence of cycles/frequencies in time. The results highlight that the precession cycles are most dominantly expressed under the 400 kyrs eccentricity maximum whereas weakly expressed during eccentricity minimum. This suggests that insolation is a key driver of the climatic variability observed at CHB throughout the last 620 kyrs. In addition, the prevalence of half-precession and obliquity signals was documented. The latter is attributed to the inter-tropical insolation gradient and not interpreted as an imprint of high latitudes forcing on climatic changes in the tropics. In addition, a windowed analysis of variability was used to detect changes in variance over time and showed that strong climate variability occurred especially along the transition from a dominant insolation-controlled humid climate background state towards a predominantly dry and less-insolation controlled climate. The last chapter dealt with non-linear aspects of climate changes represented by the sediments of the CHB. We use recurrence quantification analysis to detect non-linear changes within the potassium concentration of Chew Bahir sediment cores during the last 620 kyrs. The concentration of potassium in the sediments of the lake is subject to geochemical processes related to the evaporation rate of the lake water at the time of deposition. Based on recurrence analysis, two types of variabilities could be distinguished. Type 1 represents slow variations within the precession period bandwidth of 20 kyrs and a tendency towards extreme climatic events whereas type 2 represents fast, highly variable climatic transitions between wet and dry climate states. While type 1 variability is linked to eccentricity maxima, type 2 variability occurs during the 400 kyrs eccentricity minimum. The climate history presented here shows that during high eccentricity a strongly insolation-driven climate system prevailed, whereas during low eccentricity the climate was more strongly affected by short-term variability changes. The short-term environmental changes, reflected in the increased variability might have influenced the evolution, technological advances and expansion of early modern humans who lived in this region. In the Olorgesaille Basin the temporal changes in the occurrence of stone tools, which bracket the transition from Acheulean to Middle Stone Age (MSA) technologies at between 499-320 kyrs, could potentially correlate to the marked transition from a rather stable climate with less variability to a climate with increased variability in the CHB. We conclude that populations of early anatomically modern humans are more likely to have experienced climatic stress during episodes of low eccentricity, associated with dry and high variability climate conditions, which may have led to technological innovation, such as the transition from the Acheulean to the Middle Stone Age.}, language = {en} } @book{DuerschReinMattisetal.2022, author = {D{\"u}rsch, Falco and Rein, Patrick and Mattis, Toni and Hirschfeld, Robert}, title = {Learning from failure}, number = {145}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-528-6}, issn = {1613-5652}, doi = {10.25932/publishup-53755}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-537554}, publisher = {Universit{\"a}t Potsdam}, pages = {87}, year = {2022}, abstract = {Regression testing is a widespread practice in today's software industry to ensure software product quality. Developers derive a set of test cases, and execute them frequently to ensure that their change did not adversely affect existing functionality. As the software product and its test suite grow, the time to feedback during regression test sessions increases, and impedes programmer productivity: developers wait longer for tests to complete, and delays in fault detection render fault removal increasingly difficult. Test case prioritization addresses the problem of long feedback loops by reordering test cases, such that test cases of high failure probability run first, and test case failures become actionable early in the testing process. We ask, given test execution schedules reconstructed from publicly available data, to which extent can their fault detection efficiency improved, and which technique yields the most efficient test schedules with respect to APFD? To this end, we recover regression 6200 test sessions from the build log files of Travis CI, a popular continuous integration service, and gather 62000 accompanying changelists. We evaluate the efficiency of current test schedules, and examine the prioritization results of state-of-the-art lightweight, history-based heuristics. We propose and evaluate a novel set of prioritization algorithms, which connect software changes and test failures in a matrix-like data structure. Our studies indicate that the optimization potential is substantial, because the existing test plans score only 30\% APFD. The predictive power of past test failures proves to be outstanding: simple heuristics, such as repeating tests with failures in recent sessions, result in efficiency scores of 95\% APFD. The best-performing matrix-based heuristic achieves a similar score of 92.5\% APFD. In contrast to prior approaches, we argue that matrix-based techniques are useful beyond the scope of effective prioritization, and enable a number of use cases involving software maintenance. We validate our findings from continuous integration processes by extending a continuous testing tool within development environments with means of test prioritization, and pose further research questions. We think that our findings are suited to propel adoption of (continuous) testing practices, and that programmers' toolboxes should contain test prioritization as an existential productivity tool.}, language = {en} } @article{Duerr2001, author = {D{\"u}rr, Heiner}, title = {Handreichungen f{\"u}r diskursive Geographien}, series = {Geographische Revue : Zeitschrift f{\"u}r Literatur und Diskussion}, volume = {3}, journal = {Geographische Revue : Zeitschrift f{\"u}r Literatur und Diskussion}, number = {2}, issn = {1438-3039}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-24385}, pages = {55 -- 90}, year = {2001}, abstract = {Inhalt: 1 {\"U}berblick {\"u}ber Inhalt und Tenor des Textes „Sozialgeographie" 1.1 Aufbau und Inhalte des Studienbuches 1.2 Methodische und didaktische Eigenarten des Textes 2 Ein wissenschaftssoziologischer Rahmen der Diskussion 3 Hochschullehre als wissenschaftskritischer Diskurs 3.1 „Close reading": Einblick in Umgangsweisen mit Wissensbest{\"a}ndenaus fr{\"u}herer Zeit 3.2 Empirie (methodisch-technische Zug{\"a}nge zur Realit{\"a}t) 3.3 Wie soll es heißen, wie wollen wir es nennen: Sozial- oder HumanoderAnthropogeographie? 3.4 Raumbezogenes oder raumzentriertes oder r{\"a}umliches Denken? 3.5 R{\"a}umliches im Erkl{\"a}rungszusammenhang 3.6 Werlens Nachmoderne: Die Welt, in der wir leben? 3.7 Ist Benno Werlen ein Konstruktivist? 4 Leuchtt{\"u}rme, Meilensteine, Gr{\"a}ben in der Wissenschaftslandschaft 4.1 Humangeographie als teleologischer Prozeß 4.2 Die „Sozialgeographie" in der methodenorientierten Hochschullehre 4.3 Ausblick: Vom Nach- zum Miteinander}, language = {de} } @misc{Duerr2001, author = {D{\"u}rr, Heiner}, title = {Kaldor, Mary, Neue und alte Kriege / [rezensiert von] Heiner D{\"u}rr}, series = {Geographische Revue : Zeitschrift f{\"u}r Literatur und Diskussion}, volume = {3}, journal = {Geographische Revue : Zeitschrift f{\"u}r Literatur und Diskussion}, number = {2}, issn = {1438-3039}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-24402}, pages = {95 -- 97}, year = {2001}, abstract = {Rezensiertes Werk: Kaldor, Mary: Neue und alte Kriege : organisierte Gewalt im Zeitalter der Globalisierung / Mary Kaldor.

Die Arbeit zeigt auf, dass von Beginn der Liberalisierung der kommunale Einfluss auf die {\"o}rtliche Konzessionsvergabe schrittweise und stetig beschnitten wurde, so dass gegenw{\"a}rtig ein Zustand der Aush{\"o}hlung erreicht ist, der als unzul{\"a}ssiger Eingriff in den gesch{\"u}tzten Kernbereich der kommunalen Selbstverwaltungsgarantie i.S.d. Art. 28 II GG anzusehen ist.}, language = {de} } @book{Doessel1999, author = {D{\"o}ssel, Christian}, title = {Lebenszufriedenheit unter dem Einfluß ausgew{\"a}hlter objektiver und subjektiver Faktoren im innerdeutschen Vergleich}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-10648}, publisher = {Universit{\"a}t Potsdam}, year = {1999}, abstract = {Inhalt: Von Wohlfahrt zu Lebensqualit{\"a}t zu Zufriedenheit Zufriedenheitsverteilungen Forschungshypothesen: - Alter - Materielle Situation - Geschlecht - Erwerbsstatus - Sorgen und Anomie Methode und Datenbasis Ergebnisse: - Lebenszufriedenheit und Lebenszufriedenheit}, language = {de} } @phdthesis{Doerries2024, author = {D{\"o}rries, Timo Julian}, title = {Anomalous transport and non-Gaussian dynamics in mobile-immobile models}, doi = {10.25932/publishup-63495}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-634959}, school = {Universit{\"a}t Potsdam}, pages = {ii, 177}, year = {2024}, abstract = {The mobile-immobile model (MIM) has been established in geoscience in the context of contaminant transport in groundwater. Here the tracer particles effectively immobilise, e.g., due to diffusion into dead-end pores or sorption. The main idea of the MIM is to split the total particle density into a mobile and an immobile density. Individual tracers switch between the mobile and immobile state following a two-state telegraph process, i.e., the residence times in each state are distributed exponentially. In geoscience the focus lies on the breakthrough curve (BTC), which is the concentration at a fixed location over time. We apply the MIM to biological experiments with a special focus on anomalous scaling regimes of the mean squared displacement (MSD) and non-Gaussian displacement distributions. As an exemplary system, we have analysed the motion of tau proteins, that diffuse freely inside axons of neurons. Their free diffusion thereby corresponds to the mobile state of the MIM. Tau proteins stochastically bind to microtubules, which effectively immobilises the tau proteins until they unbind and continue diffusing. Long immobilisation durations compared to the mobile durations give rise to distinct non-Gaussian Laplace shaped distributions. It is accompanied by a plateau in the MSD for initially mobile tracer particles at relevant intermediate timescales. An equilibrium fraction of initially mobile tracers gives rise to non-Gaussian displacements at intermediate timescales, while the MSD remains linear at all times. In another setting bio molecules diffuse in a biosensor and transiently bind to specific receptors, where advection becomes relevant in the mobile state. The plateau in the MSD observed for the advection-free setting and long immobilisation durations persists also for the case with advection. We find a new clear regime of anomalous diffusion with non-Gaussian distributions and a cubic scaling of the MSD. This regime emerges for initially mobile and for initially immobile tracers. For an equilibrium fraction of initially mobile tracers we observe an intermittent ballistic scaling of the MSD. The long-time effective diffusion coefficient is enhanced by advection, which we physically explain with the variance of mobile durations. Finally, we generalize the MIM to incorporate arbitrary immobilisation time distributions and focus on a Mittag-Leffler immobilisation time distribution with power-law tail ~ t^(-1-mu) with 0
