The Katholische Universität Eichstätt-Ingolstadt is a Roman Catholic university in Eichstätt and Ingolstadt, Bavaria, Germany.The Catholic University Eichstätt-Ingolstadt is the only Roman Catholic university in the German-speaking world. Compared to other German universities it is a rather small institution ; nevertheless, it is the largest private university in Germany. The university has one campus in Eichstätt situated in the Altmühltal Nature Park and another campus in Ingolstadt, one of Germany's economically most successful cities. Wikipedia.

Geomorphology | Year: 2013

Through their relevance for sediment budgets and the sensitivity of geomorphic systems, geomorphic coupling and (sediment) connectivity represent important topics in geomorphology. Since the introduction of the systems perspective to physical geography by Chorley and Kennedy (1971), a catchment has been perceived as consisting of landscape elements (e.g. landforms, subcatchments) that are coupled by geomorphic processes through sediment transport. In this study, we present a novel application of mathematical graph theory to explore the network structure of coarse sediment pathways in a central alpine catchment. Numerical simulation models for rockfall, debris flows, and (hillslope and channel) fluvial processes are used to establish a spatially explicit graph model of sediment sources, pathways and sinks. The raster cells of a digital elevation model form the nodes of this graph, and simulated sediment trajectories represent the corresponding edges. Model results are validated by visual comparison with the field situation and aerial photos. The interaction of sediment pathways, i.e. where the deposits of a geomorphic process form the sources of another process, forms sediment cascades, represented by paths (a succession of edges) in the graph model. We show how this graph can be used to explore upslope (contributing area) and downslope (source to sink) functional connectivity by analysing its nodes, edges and paths. The analysis of the spatial distribution, composition and frequency of sediment cascades yields information on the relative importance of geomorphic processes and their interaction (however regardless of their transport capacity). In the study area, the analysis stresses the importance of mass movements and their interaction, e.g. the linkage of large rockfall source areas to debris flows that potentially enter the channel network. Moreover, it is shown that only a small percentage of the study area is coupled to the channel network which itself is longitudinally disconnected by natural and anthropogenic barriers. Besides the case study, we discuss the methodological framework and alternatives for node and edge representations of graph models in geomorphology. We conclude that graph theory provides an excellent methodological framework for the analysis of geomorphic systems, especially for the exploration of quantitative approaches towards sediment connectivity. © 2012 Elsevier B.V.

This empirical study investigates the environmental awareness of school children in Bavaria and Asturias. The analysis was based on a data-set (Bavaria, 900 students; Asturias, 182 students) that was collected in spring 2007. Students aged between 14 and 15 years responded to a paper-and-pencil questionnaire. The theoretical concept follows the premise that environmental awareness could be divided into three dimensions: environmental knowledge, attitudes and actions. The results show that there are cultural influences in the scales of knowledge, attitudes and actions. Also, different independent variables have a significant bearing on the Bavarian and Asturian students' levels of environmental knowledge, readiness to act and personal environmental action. © 2010 Taylor & Francis.

Errors in choice tasks have been shown to elicit a cascade of characteristic components in the human event-related potential (ERPs)-the error-related negativity (Ne/ERN) and the error positivity (Pe). Despite the large number of studies concerned with these components, it is still unclear how they relate to error awareness as measured by overt error signaling responses. In the present study, we considered error awareness as a decision process in which evidence for an error is accumulated until a decision criterion is reached, and hypothesized that the Pe is a correlate of the accumulated decision evidence. To test the prediction that the amplitude of the Pe varies as a function of the strength and latency of the accumulated evidence for an error, we manipulated the speed-accuracy trade-off (SAT) in a brightness discrimination task while participants signaled the occurrence of errors. Based on a previous modeling study, we predicted that lower speed pressure should be associated with weaker evidence for an error and, thus, with smaller Pe amplitudes. As predicted, average Pe amplitude was decreased and error signaling was impaired in a low speed pressure condition compared to a high speed pressure condition. In further analyses, we derived single-trial Pe amplitudes using a logistic regression approach. Single-trial amplitudes robustly predicted the occurrence of signaling responses on a trial-by-trial basis. These results confirm the predictions of the evidence accumulation account, supporting the notion that the Pe reflects accumulated evidence for an error and that this evidence drives the emergence of error awareness. © 2012 Steinhauser and Yeung.

Nearly all risks associated with infectious diseases have potential global implications and highlight Beck's (2007, Weltrisikogesellschaft. auf der suche nach der verlorenen sicherheit. Frankfurt am Main: Suhrkamp Verlag) famous thesis that the risk society is always a world risk society. One central factor behind the immanently global nature of risk is the role of mediated communication. All risks are mediated in one form or another. It is for that reason logical that mediation - as a process of coming in between or extending particular associations - should play a major role in the development of theories of risk. It is from this starting point that I propose to retheorise risk in relation to practices of communication. I will reflect on two well-documented cases: Bovine Spongiform Encephalopathy (BSE or 'mad cow disease') and avian influenza (H5N1) to develop an analysis of the role of media in engendering particular risk sensibilities. By invoking Bolter and Grusin's (1999, Remediation: understanding new media. Cambridge MA: MIT Press) concept of remediation, I will show that risks are virtual and this means that they can be endlessly reconfigured in particular techno-semiotic networks that are geared towards calibrating three attributions: matter, energy and information. It is through these recalibrations that particular systems are able to invoke specific forms of risk communication that fit distinct institutional and/or personal interests. © 2014 Taylor & Francis.

Posttraumatic stress disorder (PTSD) has been discussed mostly in connection with sexual or physical violence, war, natural disasters, and accidents. However, there is evidence that a small percentage of women can develop clinically relevant posttraumatic symptoms after giving birth to a child. The epidemiological research on PTSD following childbirth is reviewed and possible reasons for diverging results are discussed. Difficulties connected to this disorder as well as the state of evidence on factors that influence and predict its development are summarized. Individual vulnerability factors and factors related to the birth itself influence the development of the disorder. © 2014 Verlag Hans Huber, Hogrefe AG.
