Die Colonia Dignidad (dt.: Kolonie der W{\"u}rde) wurde 1961 von Mitgliedern einer deutschen Sekte im Zentrum des Landes, ca. 400 km s{\"u}dlich von Santiago entfernt, gegr{\"u}ndet. Nach außen pr{\"a}sentierte sich die Gemeinschaft als gl{\"u}ckliche und zufriedene deutsche Enklave, die ihre heimatlichen Traditionen und Br{\"a}uche im Ausland weiterhin pflegt. Mit dem Ende der Milit{\"a}rdiktatur unter Augusto Pinochet 1990 und dem damit verbundenen Wegfall der politischen R{\"u}ckendeckung der Gemeinschaft, begann die chilenische Justiz die schon l{\"a}nger bestehenden Vorw{\"u}rfe gegen den damaligen Sektenf{\"u}hrer Paul Sch{\"a}fer, u. a. wegen Kindesmissbrauchs und Folter an chilenischen Oppositionellen w{\"a}hrend der Milit{\"a}rdiktatur, zu untersuchen. Dem chilenischen Haftbefehl acht Jahre sp{\"a}ter entzog sich Paul Sch{\"a}fer durch seine Flucht nach Argentinien. Die zur{\"u}ckbleibenden Mitglieder der Colonia Dignidad waren aufgrund des einsetzenden Zerfalls der alten Gemeinschaftsordnung gezwungen, sich ein neues Gemeinschaftskonzept zu erarbeiten, eines, in dem die bisher so dominante F{\"u}hrerfigur fehlte. Sowohl das Gemeinschaftsleben in der Colonia Dignidad zwischen 1961 und 1998 als auch das Zusammenleben in der heutigen Villa Baviera ab 1998 wird anhand der Theorien zur Gemeinschaftsforschung von Ferdinand T{\"o}nnies, Georg Vobruba, Zygmunt Baumann, Matthias Grundmann und Stephan Drucks analysiert. Im Findungsprozess eines neuen Gemeinschaftskonzeptes waren die Mitglieder der ehemaligen Colonia Dignidad gezwungen, sich mit der Vergangenheit auseinanderzusetzen. In diesem Zusammenhang wird der Frage nachgegangen, inwiefern eine Aufarbeitung der Vergangenheit (memoria) im kulturwissenschaftlichen und psychologischen Sinne stattfand bzw. stattfindet und wenn ja, wie sich diese gestaltete bzw. gestaltet. Hierzu wird untersucht, welche staatlichen Maßnahmen zur Unterst{\"u}tzung des Neuanfangs der Gemeinschaft getroffen wurden und welchen Erfolg diese Maßnahmen hatten.

One of the problems is the expensive and mostly custom made equipment which is needed for their development. We intended to reduce material costs and aimed at miniaturization of the necessary tools that are essential for nanofabrication. Thus we combined the capabilities of molecular ink lithography with DNA-self-assembling capabilities to arrange DNA in an independent array which allows addressing molecules in nanoscale dimensions. Results: For the construction of DNA based nanostructures a method is presented that allows an arrangement of DNA strands in such a way that they can form a grid that only depends on the spotted pattern of the anchor molecules. An atomic force microscope (AFM) has been used for molecular ink lithography to generate small spots. The sequential spotting process allows the immobilization of several different functional biomolecules with a single AFM-tip. This grid which delivers specific addresses for the prepared DNA-strand serves as a two-dimensional anchor to arrange the sequence according to the pattern. Once the DNA-nanoarray has been formed, it can be functionalized by PNA (peptide nucleic acid) to incorporate advanced structures. Conclusions: The production of DNA-nanoarrays is a promising task for nanobiotechnology. The described method allows convenient and low cost preparation of nanoarrays. PNA can be used for complex functionalization purposes as well as a structural element.}, language = {en} } @misc{BierbachSchulteHerrmannetal.2011, author = {Bierbach, David and Schulte, Matthias and Herrmann, Nina and Tobler, Michael and Stadler, Stefan and Jung, Christian T. and Kunkel, Benjamin and Riesch, R{\"u}diger and Klaus, Sebastian and Ziege, Madlen and Indy, Jeane Rimber and Arias-Rodriguez, Lenin and Plath, Martin}, title = {Predator-induced changes of female mating preferences}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, number = {984}, issn = {1866-8372}, doi = {10.25932/publishup-43109}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-431099}, pages = {12}, year = {2011}, abstract = {Background In many species males face a higher predation risk than females because males display elaborate traits that evolved under sexual selection, which may attract not only females but also predators. Females are, therefore, predicted to avoid such conspicuous males under predation risk. The present study was designed to investigate predator-induced changes of female mating preferences in Atlantic mollies (Poecilia mexicana). Males of this species show a pronounced polymorphism in body size and coloration, and females prefer large, colorful males in the absence of predators. Results In dichotomous choice tests predator-na{\"i}ve (lab-reared) females altered their initial preference for larger males in the presence of the cichlid Cichlasoma salvini, a natural predator of P. mexicana, and preferred small males instead. This effect was considerably weaker when females were confronted visually with the non-piscivorous cichlid Vieja bifasciata or the introduced non-piscivorous Nile tilapia (Oreochromis niloticus). In contrast, predator experienced (wild-caught) females did not respond to the same extent to the presence of a predator, most likely due to a learned ability to evaluate their predators' motivation to prey. Conclusions Our study highlights that (a) predatory fish can have a profound influence on the expression of mating preferences of their prey (thus potentially affecting the strength of sexual selection), and females may alter their mate choice behavior strategically to reduce their own exposure to predators. (b) Prey species can evolve visual predator recognition mechanisms and alter their mate choice only when a natural predator is present. (c) Finally, experiential effects can play an important role, and prey species may learn to evaluate the motivational state of their predators.}, language = {en} } @misc{LamprechtNaujokatMargariaetal.2011, author = {Lamprecht, Anna-Lena and Naujokat, Stefan and Margaria, Tiziana and Steffen, Bernhard}, title = {Semantics-based composition of EMBOSS services}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch-Naturwissenschaftliche Reihe}, number = {956}, issn = {1866-8372}, doi = {10.25932/publishup-43183}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-431830}, pages = {23}, year = {2011}, abstract = {Background More than in other domains the heterogeneous services world in bioinformatics demands for a methodology to classify and relate resources in a both human and machine accessible manner. The Semantic Web, which is meant to address exactly this challenge, is currently one of the most ambitious projects in computer science. Collective efforts within the community have already led to a basis of standards for semantic service descriptions and meta-information. In combination with process synthesis and planning methods, such knowledge about types and services can facilitate the automatic composition of workflows for particular research questions. Results In this study we apply the synthesis methodology that is available in the Bio-jETI workflow management framework for the semantics-based composition of EMBOSS services. EMBOSS (European Molecular Biology Open Software Suite) is a collection of 350 tools (March 2010) for various sequence analysis tasks, and thus a rich source of services and types that imply comprehensive domain models for planning and synthesis approaches. We use and compare two different setups of our EMBOSS synthesis domain: 1) a manually defined domain setup where an intuitive, high-level, semantically meaningful nomenclature is applied to describe the input/output behavior of the single EMBOSS tools and their classifications, and 2) a domain setup where this information has been automatically derived from the EMBOSS Ajax Command Definition (ACD) files and the EMBRACE Data and Methods ontology (EDAM). Our experiments demonstrate that these domain models in combination with our synthesis methodology greatly simplify working with the large, heterogeneous, and hence manually intractable EMBOSS collection. However, they also show that with the information that can be derived from the (current) ACD files and EDAM ontology alone, some essential connections between services can not be recognized. Conclusions Our results show that adequate domain modeling requires to incorporate as much domain knowledge as possible, far beyond the mere technical aspects of the different types and services. Finding or defining semantically appropriate service and type descriptions is a difficult task, but the bioinformatics community appears to be on the right track towards a Life Science Semantic Web, which will eventually allow automatic service composition methods to unfold their full potential.}, language = {en} } @misc{BoumaHendriks2011, author = {Bouma, Gerlof J. and Hendriks, Petra}, title = {Partial word order freezing in Dutch}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {625}, issn = {1866-8364}, doi = {10.25932/publishup-43049}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-430496}, pages = {23}, year = {2011}, abstract = {Dutch allows for variation as to whether the first position in the sentence is occupied by the subject or by some other constituent, such as the direct object.

The capability of primary producers to defend themselves against herbivores affects their own survival, can modulate the strength of trophic cascades and changes rates of competitive exclusion in aquatic communities. Algal species are highly flexible in their morphology, growth form, biochemical composition and production of toxic and deterrent compounds. Several of these variable traits in phytoplankton have been interpreted as defence mechanisms against grazing. Zooplankton feed with differing success on various phytoplankton species, depending primarily on size, shape, cell wall structure and the production of toxins and deterrents. Chemical cues associated with (i) mechanical damage, (ii) herbivore presence and (iii) grazing are the main factors triggering induced defences in both marine and freshwater phytoplankton, but most studies have failed to disentangle the exact mechanism(s) governing defence induction in any particular species. Induced defences in phytoplankton include changes in morphology (e.g. the formation of spines, colonies and thicker cell walls), biochemistry (such as production of toxins, repellents) and in life history characteristics (formation of cysts, reduced recruitment rate). Our categorization of inducible defences in terms of the responsible induction mechanism provides guidance for future work, as hardly any of the available studies on marine or freshwater plankton have performed all the treatments that are required to pinpoint the actual cue(s) for induction.

Gluten proteins were digested by F. graminearum proteases for 2, 4, 8 and 24 h, separated by Osborne fractionation and characterised by chromatographic (RP-HPLC) and electrophoretic analysis (SDS-Page). Gluten digestion by F. graminearum proteases showed in comparison with gliadins a preference for the glutenins whereas the HMW subfraction was at most affected. In comparison with a untreated control, the HMW subfraction was degraded of about 97\% after 4 h incubation with Fusarium proteases. Separate digestion of gliadin and glutenin underlined the preference for HMW-GS. Analogue to the observed change in the gluten composition, the yield of the proteins extracted changed. A higher amount of glutenin fragments was found in the gliadin extraction solution after digestion and could mask a gliadin destruction at the same time.

Riociguat has a dual mode of action: it sensitizes sGC to the body's own NO and can also increase sGC activity in the absence of NO. The NO-sGC-pathway is impaired in many cardiovascular diseases such as heart failure, pulmonary hypertension and diabetic nephropathy (DN). DN leads to high cardiovascular morbidity and mortality. There is still a high unmet medical need. The urinary albumin excretion rate is a predictive biomarker for these clinical events. Therefore, we investigated the effect of riociguat, alone and in combination with the angiotensin II receptor antagonist (ARB) telmisartan on the progression of DN in diabetic eNOS knock out mice, a new model closely resembling human pathology. Methods Seventy-six male eNOS knockout C57BL/6J mice were divided into 4 groups after receiving intraperitoneal high-dose streptozotocin: telmisartan (1 mg/kg), riociguat (3 mg/kg), riociguat+telmisartan (3 and 1 mg/kg), and vehicle. Fourteen mice were used as non-diabetic controls. After 12 weeks, urine and blood were obtained and blood pressure measured. Glucose concentrations were highly increased and similar in all diabetic groups. Results Riociguat, alone (105.2 ± 2.5 mmHg; mean±SEM; n = 14) and in combination with telmisartan (105.0 ± 3.2 mmHg; n = 12), significantly reduced blood pressure versus diabetic controls (117.1 ± 2.2 mmHg; n = 14; p = 0.002 and p = 0.004, respectively), whereas telmisartan alone (111.2 ± 2.6 mmHg) showed a modest blood pressure lowering trend (p = 0.071; n = 14). The effects of single treatment with either riociguat (97.1 ± 15.7 µg/d; n = 13) or telmisartan (97.8 ± 26.4 µg/d; n = 14) did not significantly lower albumin excretion on its own (p = 0.067 and p = 0.101, respectively). However, the combined treatment led to significantly lower urinary albumin excretion (47.3 ± 9.6 µg/d; n = 12) compared to diabetic controls (170.8 ± 34.2 µg/d; n = 13; p = 0.004), and reached levels similar to non-diabetic controls (31.4 ± 10.1 µg/d, n = 12). Conclusion Riociguat significantly reduced urinary albumin excretion in diabetic eNOS knock out mice that were refractory to treatment with ARB's alone. Patients with diabetic nephropathy refractory to treatment with ARB's have the worst prognosis among all patients with diabetic nephropathy. Our data indicate that additional stimulation of sGC on top of standard treatment with ARB`s may offer a new therapeutic approach for patients with diabetic nephropathy resistant to ARB treatment.}, language = {en} } @misc{IdzikCywinskiCranfieldetal.2011, author = {Idzik, Krzysztof Ryszard and Cywinski, Piotr J. and Cranfield, Charles G. and Mohr, Gerhard J. and Beckert, Rainer}, title = {Molecular recognition of the antiretroviral drug Abacavir}, series = {Postprints der Universit{\"a}t Potsdam : Mathematisch Naturwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Mathematisch Naturwissenschaftliche Reihe}, number = {847}, issn = {1866-8372}, doi = {10.25932/publishup-43037}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-430372}, pages = {1195 -- 1204}, year = {2011}, abstract = {Due to their optical and electro-conductive attributes, carbazole derivatives are interesting materials for a large range of biosensor applications.

This effect has been explained by possible preactivation of the saccadic circuitry whenever a structured background acts as a mask for potential saccade targets. Here, we show that background textures modulate rates of microsaccades during visual fixation. First, after a display change, structured backgrounds induce a stronger decrease of microsaccade rates than do uniform backgrounds. Second, we demonstrate that the occurrence of a microsaccade in a critical time window can delay a subsequent saccadic response.

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} } @book{MelzerSchubarthEhninger2011, author = {Melzer, Wolfgang and Schubarth, Wilfried and Ehninger, Frank}, title = {Gewaltpr{\"a}vention und Schulentwicklung}, series = {UTB ; 3477}, journal = {UTB ; 3477}, edition = {2., {\"u}berarb.

With great regularity, particular species establish only poorly. More reliable establishment could improve outcome of restoration projects and increase cost-effectiveness. We investigated the abiotic germination niche of ten poorly establishing calcareous grassland species by simultaneously exploring the effects of moisture and light availability and temperature fluctuation on percentage germina- tion and speed of germination. We also investigated the effects of three different pre-treatments used to enhance seed germination - cold-stratification, osmo- tic priming and priming in combination with gibberellic acid (GA 3 ) - and how these affected abiotic germination niches. Species varied markedly in width of abiotic germination niche, ranging from Carex flacca with very strict abiotic requirements, to several species reliably germinating across the whole range of abiotic conditions. Our results suggest pronounced differ- ences between species in gap requirements for establishment. Germination was improved in most species by at least one pre-treatment. Evidence for positive effects of adding GA 3 to seed priming solutions was limited. In several species, pre-treated seeds germinated under a wider range of abiotic conditions than untreated seeds. Improved knowledge of species-specific germination niches and the effects of seed pre-treatments may help to improve species establishment by sowing, and to identify species for which sowing at a later stage of restoration or introduction as small plants may represent a more viable strategy.}, language = {en} } @misc{Vicente2011, author = {Vicente, Luis}, title = {{\´A}ngel J.

However, since IR theory has damagingly neglected history in the last decades, the works under review here, at least in part, compensate for this disciplinary and intellectual failure.

Additionally, changes in PTM of the protein transthyretin (TTR) were analysed. Serum protein profiles of each species (five animals per species) were determined using strong anion exchanger ProteinChips (R) (Bio-Rad, Munich, Germany) in combination with surface-enhanced laser desorption ionisation-time of flight MS. The PTM of TTR were analysed subsequently by immunoprecipitation in combination with matrix-assisted laser desorption ionisation-time of flight MS.

In this paper, we reformulate the definition of an elementary loop, extend it to disjunctive programs, and study several properties of elementary loops, including how maximal elementary loops are related to minimal unfounded sets. The results provide useful insights into the stable model semantics in terms of elementary loops. For a nondisjunctive program, using a graph-theoretic characterization of an elementary loop, we show that the problem of recognizing an elementary loop is tractable. On the other hand, we also show that the corresponding problem is coNP-complete for a disjunctive program.

Diffuse X-ray emission associated with the petal-like features and one of the H-poor knots seen in the optical is also found.

Our aim is to provide a declarative solution to the problem by appeal to Answer Set Programming (ASP) overcoming these difficulties. We build upon an existing approach to Automatic Network Reconstruction proposed by part of the authors. This approach has firm mathematical foundations and is well suited for ASP due to its combinatorial flavor providing a characterization of all models explaining a set of experiments. The usage of ASP has several benefits over the existing heuristic algorithms. First, it is declarative and thus transparent for biological experts. Second, it is elaboration tolerant and thus allows for an easy exploration and incorporation of biological constraints. Third, it allows for exploring the entire space of possible models.

Rather, such complex criteria are typically addressed by resorting to dedicated modeling techniques, like saturation. Unlike the ease of common ASP modeling, however, these techniques are rather involved and hardly usable by ASP laymen. We address this problem by developing a general implementation technique by means of meta-prpogramming, thus reusing existing ASP systems to capture various forms of qualitative preferences among answer sets.

Using a general instead of a sport-specific measure, a previous study provided only mixed support for core predictions of the theory as related to sports (Schwenkmezger, 1985). With the aid of enhanced instruments and statistical methods, we tested these predictions again. The multidimensional and competition-specific assessment of anxiety results in support for the assumption of a stable A-trait and a fluctuating A-state, whereby the A-trait not only predicts the intensity of A-states but also the A-state variability. The repeated assessment of A-states prior to two competitions reveals a rather low relative consistency (i.e., interindividual differences across measurements were only moderately stable). Especially this latter finding suggests that, in order to gain a full understanding of the experience of competitive anxiety in athletes, sport psychologists should not only assess competitive A-traits, but also repeatedly measure competitive A-states.}, language = {de} } @misc{Kossack2011, author = {Kossack, Peter}, title = {Discourse analysis meets governmentality research perspectives on the relationship of subject. language, power and knowledge}, series = {Zeitschrift f{\"u}r Soziologie der Erziehung und Sozialisation}, volume = {31}, journal = {Zeitschrift f{\"u}r Soziologie der Erziehung und Sozialisation}, number = {3}, publisher = {Juventa-Verl.}, address = {Weinheim}, issn = {1436-1957}, pages = {328 -- 329}, year = {2011}, language = {de} } @article{Hoeppner2011, author = {H{\"o}ppner, Till}, title = {Kant's Notion of the function and the completeness of the ruling class and blackboard}, series = {Zeitschrift f{\"u}r philosophische Forschung : Abhandlungen, Diskussionen und Berichte}, volume = {65}, journal = {Zeitschrift f{\"u}r philosophische Forschung : Abhandlungen, Diskussionen und Berichte}, number = {2}, publisher = {Klostermann}, address = {Frankfurt, Main}, issn = {0044-3301}, pages = {193 -- 240}, year = {2011}, language = {de} } @article{KampaKunterMaazetal.2011, author = {Kampa, Nele and Kunter, Mareike and Maaz, Kai and Baumert, J{\"u}rgen}, title = {The social background of maths teachers in Germany its connection with professional occupation and job-related convictions among teachers at secondary schools}, series = {Zeitschrift f{\"u}r P{\"a}dagogik}, volume = {57}, journal = {Zeitschrift f{\"u}r P{\"a}dagogik}, number = {1}, publisher = {Beltz}, address = {Weinheim}, issn = {0044-3247}, pages = {70 -- 92}, year = {2011}, abstract = {The present article analyzes the socio-economic background of maths teachers in Germany and its relation to career-related decisions and job-related convictions.

This article tests the impact of three frequently discussed variables in the political opportunity structure of ERPs (mainstream party convergence, position of the established right and party system polarisation) on the vote share of ERPs in Western Europe. In addition to examining previous studies in this field, it focuses on the interplay between the economic and the cultural dimensions as part of the political opportunity structure. The authors show that a decrease in polarisation with regard to economic questions is accompanied by a growing salience of ERPs' core issues, leading in the end to an increase in ERPs' vote share.}, language = {en} } @article{AkalKoralayCandanetal.2011, author = {Akal, Cuneyt and Koralay, O.

These mixtures were studied at a constant total concentration of 50 mM and characterised by means of dynamic light scattering (DLS), electric conductivity, small-angle neutron scattering (SANS), viscosity, and cryo-scanning electron microscopy (Cryo-SEM). No vesicles are formed for relatively short perfluoro surfactants. The extension of the vesicle phase becomes substantially larger with increasing chain length of the perfluoro surfactant, while at the same time the size of these vesicles increases. Head group interactions in these systems play a central role in the ability to form vesicles, as already protonating 10 mol\% of the TDMAO largely enhances the propensity for vesicle formation. The range of vesicle formation in the phase diagram is not only substantially enlarged but also extends to shorter perfluoro surfactants, where without protonation no vesicles would be formed. The size and polydispersity of the vesicles are related to the chain length of the perfluoro surfactant, the vesicles becoming smaller and more monodisperse with increasing perfluoro surfactant chain length. The ability of the mixed systems to form well-defined unilamellar vesicles accordingly can be controlled by the length of the alkyl chain of the perfluorinated surfactant and depends strongly on the charge conditions, which can be tuned easily by pH-variation.}, language = {en} } @article{SangoroIacobNaumovetal.2011, author = {Sangoro, J.

Using a twofold trimethylsilyl (TMS)-labeled RAFT-agent, the relative size of the two blocks was varied. While soluble as unimers below 15 degrees C, all copolymers exhibited thermally induced two-step self-assembly in water, due to distinct lower critical solution temperature (LCST) phase transitions of PNPAM (around 20 degrees C) and PNEAM (around 70 degrees C). Their temperature-dependent self-organisation in dilute aqueous solution was studied by turbidimetry, dynamic light scattering, transmission electron microscopy, and (1)H NMR spectroscopy. The copolymers show distinct, two-step self-organisation behaviour with respect to transition temperatures, aggregate type and size, which can be correlated to the relative lengths of the low and high LCST blocks. For polymers having short blocks with low LCST, the first thermal transition induces the formation of individual micelles. Further heating above the second thermal transition results reversibly either in a shrink of the micelle size or in aggregation of the micelles, with hydrodynamic diameters below 250 nm. In contrast in the case of polymers having a long block with low LCST, the first thermal transition already leads to clusters of micelles, while the second thermal transition makes the clusters shrink. Noteworthy, the twofold TMS-labeled end groups report not only on the molar masses of the polymers, but can simultaneously serve as NMR-probes for the self-assembly process. The signal of the TMS-aryl end group displays a reversible temperature dependent, two-step splitting that is indicative of the self-organisation of the block copolymers.}, language = {en} } @article{StoyanovKolloscheRisseetal.2011, author = {Stoyanov, Hristiyan and Kollosche, Matthias and Risse, Sebastian and McCarthy, Denis N. and Kofod, Guggi}, title = {Elastic block copolymer nanocomposites with controlled interfacial interactions for artificial muscles with direct voltage control}, series = {Soft matter}, volume = {7}, journal = {Soft matter}, number = {1}, publisher = {Royal Society of Chemistry}, address = {Cambridge}, issn = {1744-683X}, doi = {10.1039/c0sm00715c}, pages = {194 -- 202}, year = {2011}, abstract = {Soft, physically crosslinking, block copolymer elastomers were filled with surface-treated nanoparticles, in order to evaluate the possibility for improvement of their properties when used as soft dielectric actuators.

Depending on the polymer chemistry and architecture, various types of organization at interfaces can be expected, and further exploited for applications in nanotechnology, electronics, and biomedical sciences.

To investigate the response of lake ecosystems to climatic changes, statistical comparisons were made between the lake Kuhai pollen record and a formerly published ostracod and sedimentary record from the same sediment core. Furthermore, the pollen and lacustrine proxies from lake Kuhai were compared to a previously published pollen and lacustrine record from the nearby Lake Koucha. Statistical comparisons were done using non-metric multidimensional scaling and Procrustes rotation. Differences between lacustrine and pollen responses within one site could be identified, suggesting that lacustrine proxies are partly influenced by in-lake or local catchment processes, whereas the terrestrial (pollen) proxy shows a regional climate signal. Furthermore, we found regional differences in proxy response between lake Kuhai and Lake Koucha. Both pollen records reacted in similar ways to major environmental changes, with minor differences in the timing and magnitude of these changes. The lacustrine records were very similar in their timing and magnitude of response to environmental changes; however, the nature of change was at times very distinct. To place the current study in the context of Holocene moisture evolution across the Tibetan Plateau, we applied a five-scale moisture index and average link clustering to all available continuous palaeo-climate records from the Tibetan Plateau to possibly find general patterns of moisture evolution on the Plateau. However, no common regional pattern of moisture evolution during the Holocene could be detected.

Stability of psychotherapeutic treatment effects over time was demonstrated.}, language = {de} } @article{MohnkeWarschburger2011, author = {Mohnke, Sebastian and Warschburger, Petra}, title = {Body dissatisfaction among female and male adolescents comparing prevalence, predictors, and consequences between the sexes}, series = {Praxis der Kinderpsychologie und Kinderpsychiatrie : Ergebnisse aus Psychotherapie, Beratung und Psychiatrie}, volume = {60}, journal = {Praxis der Kinderpsychologie und Kinderpsychiatrie : Ergebnisse aus Psychotherapie, Beratung und Psychiatrie}, number = {4}, publisher = {Vandenhoeck \& Ruprecht}, address = {G{\"o}ttingen}, issn = {0032-7034}, pages = {285 -- 303}, year = {2011}, abstract = {As part of the POPS study (Potsdam prevention of eating disorders) 300 adolescents aged between 10 and 13 years completed questionnaires measuring satisfaction with weight and muscles, body change strategies and disturbed eating behavior. More than half of the girls and a third of the boys are dissatisfied with their weight. Nearly 70\% of the male participants were unhappy with their muscles. Both forms of body dissatisfaction are influenced by similar sociocultural and psychological factors. While weight dissatisfaction leads to weight reduction strategies and disturbed eating, muscle dissatisfaction results in muscle enhancement methods. Potential harmful consequences of excessive muscle building techniques are discussed. The data emphasize the need for a sex-specific investigation of body dissatisfaction and its consequences. Body image aspects relevant to boys should be added to intervention and prevention approaches.}, language = {de} }
