Complex problem solving: What it is and what it is not

Computer-simulated scenarios have been part of psychological research on problem solving for more than 40 years. The shift in emphasis from simple toy problems to complex, more real-life oriented problems has been accompanied by discussions about the best ways to assess the process of solving complex problems. Psychometric issues such as reliable assessments and addressing correlations with other instruments have been in the foreground of these discussions and have left the content validity of complex problem solving in the background. In this paper, we return the focus to content issues and address the important features that define complex problems

Proceedings of KogWis 2012. 11th Biannual Conference of the German Cognitive Science Society

The German cognitive science conference is an interdisciplinary event where researchers from different disciplines -- mainly from artificial intelligence, cognitive psychology, linguistics, neuroscience, philosophy of mind, and anthropology -- and application areas -- such as eduction, clinical psychology, and human-machine interaction -- bring together different theoretical and methodological perspectives to study the mind. The 11th Biannual Conference of the German Cognitive Science Society took place from September 30 to October 3 2012 at Otto-Friedrich-Universität in Bamberg. The proceedings cover all contributions to this conference, that is, five invited talks, seven invited symposia and two symposia, a satellite symposium, a doctoral symposium, three tutorials, 46 abstracts of talks and 23 poster abstracts

Second life, Avatare, Cyberwelt - Gibt es ein zweites Leben? : Bamberger Hegelwoche 2008

Bamberger Hegelwoche 2008. Mit Einführungen von Roland Simon-Schaefer sowie einer Podiumsdiskussion zum Thema "Identität und Religion - gibt es ein zweites Leben?" Ach, Sie sind neu hier? Dann bestimmen Sie bitte zunächst einmal Ihre Identität! Heute vielleicht mal rothaarige Medienspezialistin, reich und verliebt? – Der „Newbie“ im Multiplayer-Game kreiert sich eine Wunschversion des Ich und lädt sie hoch. Das neue Leben lebt dann zwar ein Avatar für ihn, aber immerhin. Der Traum von einem anderen Leben ist so alt wie die Menschheit. Neu sind heute die nahezu unbegrenzten Möglichkeiten der Selbstverwirklichung und Kommunikation in den virtuellen Welten des Internet. Mit bald elf Millionen registrierten Nutzern allein im 3-D-Online-Spiel Second Life ist der Cyberspace schon ziemlich voll. Steckt dahinter die Sehnsucht nach einer anderen Identität? Oder nach einer Antwort auf die großen Fragen: Wer bin ich? Und wodurch? Wie virtuell ist das wirkliche Leben geworden – und wieviel wirkliches Leben steckt im virtuellen

Mapping the spatial distribution of NO2 with in situ and remote sensing instruments during the Munich NO2 imaging campaign

We present results from the Munich Nitrogen dioxide (NO2) Imaging Campaign (MuNIC), where NO2 near-surface concentrations (NSCs) and vertical column densities (VCDs) were measured with stationary, mobile, and airborne in situ and remote sensing instruments in Munich, Germany. The most intensive day of the campaign was 7 July 2016, when the NO2 VCD field was mapped with the Airborne Prism Experiment (APEX) imaging spectrometer. The spatial distribution of APEX VCDs was rather smooth, with a horizontal gradient between lower values upwind and higher values downwind of the city center. The NO2 map had no pronounced source signatures except for the plumes of two combined heat and power (CHP) plants. The APEX VCDs have a fair correlation with mobile multi-axis differential optical absorption spectroscopy (MAX-DOAS) observations from two vehicles conducted on the same afternoon (r=0.55). In contrast to the VCDs, mobile NSC measurements revealed high spatial and temporal variability along the roads, with the highest values in congested areas and tunnels. The NOx emissions of the two CHP plants were estimated from the APEX observations using a mass-balance approach. The NOx emission estimates are consistent with CO2 emissions determined from two ground-based Fourier transform infrared (FTIR) instruments operated near one CHP plant. The estimates are higher than the reported emissions but are probably overestimated because the uncertainties are large, as conditions were unstable and convective with low and highly variable wind speeds. Under such conditions, the application of mass-balance approaches is problematic because they assume steady-state conditions. We conclude that airborne imaging spectrometers are well suited for mapping the spatial distribution of NO2 VCDs over large areas. The emission plumes of point sources can be detected in the APEX observations, but accurate flow fields are essential for estimating emissions with sufficient accuracy. The application of airborne imaging spectrometers for studying NSCs is less straightforward and requires us to account for the non-trivial relationship between VCDs and NSCs
