2016 wird man das achthundertjährige Bestehen des männlichen Zweigs des Predigerordens feiern - eine gute Gelegenheit, sich der eigenen Geschichte in ihren Höhen und Tiefen zu erinnern. Nur auf diese Weise wird es gelingen, das alte Ordensprojekt auch unter veränderten Bedingungen zukunftsfähig zu halten. »Zeitgemässe Erneuerung des Ordenslebens heisst: ständige Rückkehr zu den Quellen jedes christlichen Lebens und zum Geist des Ursprungs der einzelnen Institute, zugleich aber deren Anpassung an die veränderten Zeitverhältnisse.« (PC 2) Im Sinne der zitierten Maxime des Ordensdekrets »Perfectae caritatis« des Zweiten Vatikanischen Konzils ist das Buch ein Beitrag im Blick auf das kommende Jubiläum des Dominikanerordens.
Die nun bald 800 Jahre währende Geschichte des Dominikanerordens ist auch eine Geschichte des Ringens darum, wie Barmherzigkeit und Menschenfreundlichkeit Gottes angemessen verkündet werden können. Die Spannungsfelder von Innen und Aussen, Kirche und Welt, Glaube und Politik sind die Orte, an denen sich (nicht nur) dominikanische Theologie bewahrheiten muss. Theologen wie Thomas von Aquin, Albertus Magnus, Marie-Dominique Chenu oder Edward Schillebeeckx sind Zeugen für dieses Ringen, das Ulrich Engel geistlich inspirierend und intellektuell herausfordernd vorstellt.
Ohne Zweifel befindet sich Europa in der Krise. Sowohl das Scheitern des Verfassungsprojekts der Europäischen Union 2007 als auch der mühsame Weg bis hin zum Inkrafttreten des Reformvertrags von Lissabon 2009 sind als deren Phänomene zu lesen. Zur Diskussion steht nicht weniger als die Frage nach der kulturellen Identität des Kontinents: Wie sind in diesem Europa mit seinen heterogenen Wurzeln und geschichtlich ausgebildeten Antagonismen Einheit und Vielfalt als sich gegenseitig befruchtende "Einverschiedenheit", als "discordia concors" zu denken? Mit Jacques Derrida kann die Identität Europas als Versprechen bestimmt werden. Im philosophisch- theologischen Angang gilt es ein zukünftiges Europa zu rekonstruieren, das nicht bloss das eigene Wohl im Auge hat, sondern auch und besonders um die Anderen (jenseits der Grenzen) weiss. Vor diesem Hintergrund wird eine offene, gleichsam performative Identitätskonzeption für Europa vorgeschlagen. Ihre theologische Reflexionsgestalt findet sie im Rückgriff auf die Negative Theologie.
Ein Band zur Performativität von Texten, Zahlen und Bildern. In drei Spannungsfeldern - zwischen Diskursanalyse und Dekonstruktion, zwischen Zahl und Bild, zwischen Realitätseffekt und Spektakel - situieren sich Beiträge zu Foucault und Derrida, zu feministischer und Queer Theory, zu Wissenschaftsforschung und Medientheorie, zu Anthropologie, Statistik und Astronomie, zu Flugzeugkatastrophenfilmen, Ereignis IMAX, spektakulären Dinosaurier- Visualisierungen und zu reflexiven Bildern in Filmen der Berliner Schule und in Hanekes CACHe.

Dorothea M. Salzer untersucht die Verwendung von Bibelzitaten und -anspielungen in den hebraeischen und aramaeischen magischen Texten, die sich unter den aus der Kairoer Geniza geborgenen Handschriften finden. Die Texte datieren in die Zeit vom 10. bis zum 16. Jh. Anspielungen auf die Hebraeische Bibel spielen in fast allen diesen magischen Texten eine wichtige Rolle, sind aber bisher niemals Gegenstand einer grundlegenden und umfassenden Analyse gewesen. Vor dem Hintergrund der Intertextualitaetstheorie stellt die Autorin dar, wie die Verfasser der Texte biblische Zitate und andere Anspielungen zu magischen und rhetorischen Zwecken einsetzten und sie als magisch wirksames Mittel verwendeten. Sie erlaeutert damit, inwiefern diese Anspielungen fuer das Verstaendnis der magischen Texte bedeutsam sind. In einem Anhang werden die in den untersuchten Texten auftretenden biblischen Anspielungen uebersichtlich dargestellt.

Eye-movement control during scene viewing can be represented as a series of individual decisions about where and when to move the eyes. While substantial behavioral and computational research has been devoted to investigating the placement of fixations in scenes, relatively little is known about the mechanisms that control fixation durations. Here, we propose a computational model (CRISP) that accounts for saccade timing and programming and thus for variations in fixation durations in scene viewing. First, timing signals are modeled as continuous-time random walks. Second, difficulties at the level of visual and cognitive processing can inhibit and thus modulate saccade timing. Inhibition generates moment-by-moment changes in the random walk's transition rate and processing-related saccade cancellation. Third, saccade programming is completed in 2 stages: an initial, labile stage that is subject to cancellation and a subsequent, nonlabile stage. Several simulation studies tested the model's adequacy and generality. An initial simulation study explored the role of cognitive factors in scene viewing by examining how fixation durations differed under different viewing task instructions. Additional simulations investigated the degree to which fixation durations were under direct moment-to-moment control of the current visual scene. The present work further supports the conclusion that fixation durations, to a certain degree, reflect perceptual and cognitive activity in scene viewing. Computational model simulations contribute to an understanding of the underlying processes of gaze control.

3,4-Dihydro-2-H-pyran and oxalyl chloride react, depending on the conditions, to keto esters, a pyran-3- carboxylic acid or derivatives thereof, or to an hitherto unknown bicyclic acetal containing a vinyl chloride moiety. The structure of the latter product has been unambiguously elucidated by single-crystal X-ray structure analysis. A mechanism for its formation is proposed.
Intramolecular deactivation processes in complexes of salicylic acid or glycolic acid with Eu(III)
(2010)
The complexation of Eu(III) by 2-hydroxy benzoic acid (2HB) or glycolic acid (GL) was investigated using steady- state and time-resolved laser spectroscopy. Experiments were carried out in H2O as well as in D2O in the temperature range of View the MathML source. The Eu(III) luminescence spectra and luminescence decay times were evaluated with respect to the temperature dependence of (i) the luminescence decay time ;, (ii) the energy of the View the MathML source transition, (iii) the width of the View the MathML source transition, and (iv) the asymmetry ratio calculated from the luminescence intensities of the View the MathML source and View the MathML source transition, respectively. The differences in ligand-related luminescence quenching are discussed. Based on the temperature dependence of the luminescence decay times an activation energy for the ligand-specific non-radiative deactivation in Eu(III)-2HB or Eu(III)-GL complexes was determined. It is stressed that ligand-specific quenching processes (other than OH quenching induced by water molecules) need to be determined and considered in detail, in order to extract speciation- relevant information from luminescence data (e.g., estimation of the number of water molecules nH2O in the first coordination sphere of Eu(III)). In case of 2HB, conclusions drawn from the evaluation of the Eu(III) luminescence are compared with results of a X-ray structure analysis.
Special p-forms are forms which have components phi_{mu_1...mu_p} equal to +1,-1 or 0 in some orthonormal basis. A p-form phiin Lambda^p R^d is called democratic if the set of nonzero components {phi_{mu_1...mu_p}} is symmetric under the transitive action of a subgroup of O(d,Z) on the indices {1,...,d}. Knowledge of these symmetry groups allows us to define mappings of special democratic p-forms in d dimensions to special democratic P-forms in D dimensions for successively higher P geq p and D geq d. In particular, we display a remarkable nested stucture of special forms including a U(3)-invariant 2-form in six dimensions, a G_2-invariant 3-form in seven dimensions, a Spin(7)- invariant 4-form in eight dimensions and a special democratic 6-form Omega in ten dimensions. The latter has the remarkable property that its contraction with one of five distinct bivectors, yields, in the orthogonal eight dimensions, the Spin(7)-invariant 4-form. We discuss various properties of this ten dimensional form.
Der Aufsatz befasst sich mit der Frage, was man aus der internationalen Forschung darüber weiß, welcher Unterricht und welches Lehrerverhalten Auswirkungen auf die Lernergebnisse der Schüler/innen hat und welche Möglichkeiten es gibt, solches Verhalten zu verstärken. Berücksichtigt werden nur Forschungsergebnisse, die hohen methodischen Anforderungen genügen, kausale Schlussfolgerungen erlauben und generalisierbar sind. Konsequenzen für die Lehrerbildung werden diskutiert. #81zISSN: 784260, Hopf, Diether, dhopf@uni-potsdam.de Es gibt eine wesentlich ausführlichere Langfassung hierzu, die zeitgleich mit dem genannten Aufsatz von der Zeitschrift ins Netz gestellt worden ist unter der Adresse: http://www.dds.uni-hannover.de/fileadmin/schulentwicklungsforschung/ H3_10_09_Hopf_Erfolgreiches_Lehren_Langfassung_Web.pdf
One of the earliest categorical distinctions to be made by preverbal infants is the animate-inanimate distinction. To explore the neural basis for this distinction in 7-8-month-olds, an equal number of animal and furniture pictures was presented in an ERP-paradigm. The total of 118 pictures, all looking different from each other, were presented in a semi-randomized order for 1000 ms each. Infants' brain responses to exemplars from both categories differed systematically regarding the negative central component (Nc: 400-600 ms) at anterior channels. More specifically, the Nc was enhanced for animals in one subgroup of infants, and for furniture items in another subgroup of infants. Explorative analyses related to categorical priming further revealed category-specific differences in brain responses in the late time window (650-1550 ms) at right frontal channels: Unprimed stimuli (preceded by a different-category item) elicited a more positive response as compared to primed stimuli (preceded by a same-category item). In sum, these findings suggest that the infant's brain discriminates exemplars from both global domains. Given the design of our task, we conclude that processes of category identification are more likely to account for our findings than processes of on-line category formation during the experimental session.
Ecologists carry a well-stocked toolbox with a great variety of sampling methods, statistical analyses and modelling tools, and new methods are constantly appearing. Evaluation and optimisation of these methods is crucial to guide methodological choices. Simulating error-free data or taking high-quality data to qualify methods is common practice. Here, we emphasise the methodology of the 'virtual ecologist' (VE) approach where simulated data and observer models are used to mimic real species and how they are 'virtually' observed. This virtual data is then subjected to statistical analyses and modelling, and the results are evaluated against the 'true' simulated data. The VE approach is an intuitive and powerful evaluation framework that allows a quality assessment of sampling protocols, analyses and modelling tools. It works under controlled conditions as well as under consideration of confounding factors such as animal movement and biased observer behaviour. In this review, we promote the approach as a rigorous research tool, and demonstrate its capabilities and practical relevance. We explore past uses of VE in different ecological research fields, where it mainly has been used to test and improve sampling regimes as well as for testing and comparing models, for example species distribution models. We discuss its benefits as well as potential limitations, and provide some practical considerations for designing VE studies. Finally, research fields are identified for which the approach could be useful in the future. We conclude that VE could foster the integration of theoretical and empirical work and stimulate work that goes far beyond sampling methods, leading to new questions, theories, and better mechanistic understanding of ecological systems.
A series of nitrogen ligand (L)/copper complexes of the type [(CuL)-L-I](+), [(CuL)-L-II(X)](+) and [(CuL2)-L- I](+) (X = Cl-, BF4-, acac(-), CH3COO- and SO3CF3-) was studied in the gas phase by electrospray ionization mass spectrometry. The following ligands (L) were employed: 1,12-diazaperylene (dap), 1,1'-bisiso-quinoline (bis), 2,2'-bipyridine (bpy), 1,10-phenanthroline (phen), 2,11-disubstituted 1,12-diazaperylenes (dap), 3,3'- disubstituted 1,1'-bisisoquinoline (bis), 5,8-dimethoxy-substituted diazaperylene (meodap), 6,6'-dimethoxy- substituted bisisoquinoline (meobis) and 2,9-dimethyl-1,10-phenanthroline (dmphen). Collision-induced decomposition measurements were applied to evaluate the relative stabilities of the different copper complexes. The influence of the spatial arrangement of the ligands, of the type of substituents and of the counter ion of the copper salts employed for the complexation was examined. Correlations were found between the binding constants of the [ML2](+) complexes in solution and the relative stabilities of the analogous complexes in the gas phase. Furthermore, complexation with the ligands 2,11-dialkylated 1,12-diazaperylenes [alkyl = ethyl (dedap) and isopropyl (dipdap)] was studied in the solvents CH3OH and CH3CN.
In terms of the constructivist-orientated sociology of knowledge the social change of Christian religion turns out to be a reconstruction of central forms of knowledge. Mission and Ecumenism are two cornerstones of development This will be demonstrated using, Protestantism as an example. While the recourse on the notion of mission is enabling Christian religion to objectify itself as an integrative world religion against its societal environment, the Ecumenical leitmotif focuses on the denominational fragmented inner relations. Thereby Mission and Ecumenism are not only acting as semantics of,self-description. As distinct knowledge systems they are also standing for a programmatic change of the theological reservoir of knowledge.
We consider the suppression of spatiotemporal chaos in the complex Ginzburg-Landau equation by a combined global and local time-delay feedback. Feedback terms are implemented as a control scheme, i.e., they are proportional to the difference between the time-delayed state of the system and its current state. We perform a linear stability analysis of uniform oscillations with respect to space-dependent perturbations and compare with numerical simulations. Similarly, for the fixed-point solution that corresponds to amplitude death in the spatially extended system, a linear stability analysis with respect to space-dependent perturbations is performed and complemented by numerical simulations.
We investigate the characteristics of time-delay systems in the presence of Gaussian noise. We show that the delay time embedded in the time series of time-delay system with constant delay cannot be estimated in the presence noise for appropriate values of noise intensity thereby forbidding any possibility of phase space reconstruction. We also demonstrate the existence of complete synchronization between two independent identical time-delay systems driven by a common noise without explicitly establishing any external coupling between them.
Light switching of the activity of a coiled-coil protein, the AP-1 transcription factor, in living cells was made possible by the introduction of a designed azobenzene-cross-linked dominant negative peptide, XAFosW (red and yellow in the picture). In the dark, XAFosW showed decreased helical content and decreased affinity for target Jun proteins (green); irradiation at 365 nm enhanced helicity and target affinity.
Objectives: This study investigated the psychological as well as neuroendocrine stress response across one week before an important sport competition, introducing the cortisol awakening response (CAR) to sport psychological research. Methods: On three days in the week before the German Nationals, martial artists (N = 17) reported their competitive state anxiety and collected five samples of salivary cortisol during the first hour after awakening. Results: Hierarchic-linear models and multiple regressions were conducted. Despite a significant rise in "somatic anxiety" (p < .05), the increment of CAR across the week remained non-significant. A moderator function of competitive anxiety on the released amount of cortisol in the morning was not found significant. Results did not show any significant regression of changes in the neuroendocrine response on changes in state anxiety. Conclusion: Non- significant increments of CAR with a closer proximity to the competition may be interpreted as a possible habituation of basal hypothalamus-pituitary-adrenal activity. Moreover, athletes appear to have a lower CAR than found in norm studies, which points to further investigation of interindividual and situational effects on the temporal pattern of the neuroendocrine response to sport competitions.
