Youth, faith, climate change and environmental consciousness: A case for sustainable development
Climate change and environmental destruction are amongst the most threatening challenges to
humanity and sustainable development globally. Young people find themselves right in the
centre of debates about ecological (in)justice, environmental awareness, and climate change
discourses and practices. Youth movements worldwide, such as ‘Extinction Rebellion’ and
‘Fridays for Future,’ demonstrate that youths are concerned about environmental problems and
ready to become active in climate movements. Their willingness to act on their own behalf
makes them one of the most important and interesting groups to learn more about in relation to
the challenge of building a deeper awareness of environmental issues. Exploring and learning
how youths are engaged with these discourses, how they contribute to a wider social
consciousness of environmental issues and how such awareness is affected by different factors,
such as the role and the contribution of young people’s own religious beliefs, are, therefore, of
paramount importance
Tutorials at PPSN 2016
PPSN 2016 hosts a total number of 16 tutorials covering a broad range of current research in evolutionary computation. The tutorials range from introductory to advanced and specialized but can all be attended without prior requirements. All PPSN attendees are cordially invited to take this opportunity to learn about ongoing research activities in our field
High precision earthquake locations reveal seismogenic structure beneath Mammoth Mountain, California
In 1989, an unusual earthquake swarm occurred beneath Mammoth Mountain that was probably associated with magmatic intrusion. To improve our understanding of this swarm, we relocated Mammoth Mountain earthquakes using a double difference algorithm. Relocated hypocenters reveal that most earthquakes occurred on two structures, a near-vertical plane at 7–9 km depth that has been interpreted as an intruding dike, and a circular ring-like structure at ~5.5 km depth, above the northern end of the inferred dike. Earthquakes on this newly discovered ring structure form a conical section that dips outward away from the aseismic interior. Fault-plane solutions indicate that in 1989 the seismicity ring was slipping as a ringnormal fault as the center of the mountain rose with respect to the surrounding crust. Seismicity migrated around the ring, away from the underlying dike at a rate of ~0.4 km/ month, suggesting that fluid movement triggered seismicity on the ring fault

KOALA - ein Diamond-Open-Access-Modell als Angebot und Chance für die bibliothekarische Erwerbung
Diamond-Open-Access-Finanzierung ohne Autorengebühren kann funktionieren und hat das Potenzial, die Open-Access-Transformation sowohl maßgeblich zu beschleunigen als auch nachhaltig auszugestalten - das belegen u.a. die ersten erfolgreich erzielten KOALA-Konsortien. Doch wie können Open-Access-Konsortien für im Diamond OA erscheinende qualitätsgesicherte Publikationsorgane in Deutschland weiter ausgebaut und verankert werden?
Dieser Frage widmet sich die Arbeit des Projekts KOALA-AV ("Konsortiale Open-Access-Lösungen aufbauen, ausbauen und verankern"). Mehrere Maßnahmen sollen die Chance für einen dauerhaften Erfolg von Open-Access-Konsortien nach dem Vorbild des KOALA-Modells in Deutschland zu verbessern. Dazu gehören eine systematische Erhebung der Bedarfe der Entscheidungsträger*innen, der Aufbau von Communities aus Periodika und Bibliotheken, die Bereitstellung vereinfachter, standardisierter Abläufe zur Konsortialgründung und -durchführung, die Ermöglichung internationaler Ko-Finanzierung und die Unterstützung der Gründung von Open-Access-Konsortien an weiteren deutschen Standorten.
Der Vortrag stellt die Arbeit des Projekts KOALA-AV vor und rückt dabei neue Erkenntnisse zu verbleibenden Teilnahmehürden aus bibliothekarischer Erwerbungsperspektive sowie zur stärkeren Bedarfsorientierung der Konsortialbeteiligungsinstrumente in den Fokus.
Das vom Bundesministerium für Bildung und Forschung (BMBF) geförderte Projekt KOALA-AV wird von September 2023 bis August 2025 durch die Technische Informationsbibliothek (TIB) und das Kommunikations-, Informations-, Medienzentrum (KIM) der Universität Konstanz bearbeitet. Die im Kontext des Vorgängerprojekts KOALA (2021-2023) aufgebaute gleichnamige Dienstleistung wird an der TIB dauerhaft angeboten
Erkennung und Erschließung von Rohstoffpotentialen aus dem Hochbau
Durch die Kombination von 3D-Rekonstruktion, Bilderkennung und Semantischen Technologien soll für ressourceneffiziente Rückbau- und Abbruchmaßnahmen eine gebäudescharfe, aktuelle, kurzfristig verfügbare und vor allem verlässliche Datenbasis bereitgestellt werden, auf der wirksame Verwertungsstrategien für Wertstoffe aus dem Baubereich aufsetzen. Dies ist insbesondere für Bereiche äußerst relevant, für die derzeit keine Schätzwerte (z. B. Stahl aus Nichtwohngebäuden) oder nur große Schätz-Intervalle (z. B. Kupfer im Gebäudebestand) existieren
Experimental comparison of solid phase adsorption (SPA), activated carbon test tubes and tar protocol (DIN CEN/TS 15439) for tar analysis of biomass derived syngas
The quantification of aromatic higher hydrocarbons, so called tar compounds, is crucial for the assessment of gasification processes. The presented work compares three different sampling methods: solid phase adsorption (SPA), adsorption on activated carbon test tubes and DIN CEN/TS 15439 (‘tar-protocol’). Two different groups of operators have been sampling simultaneously in the raw syngas from a fixed-bed stratified upstream biomass gasifier in steady state operation The gathered analysis results offer the possibility to investigate the influence of sampling method, sampling equipment and operators collecting the samples. In total, 79 samples by adsorption and four wet absorption samples by DIN CEN/TS 15439 have been collected and analyzed in one single laboratory by gravimetrical analysis as well as gas chromatographic analysis of 22 tar species. In general, the gravimetric analysis of the wet samples showed much higher tar concentrations in comparison to the sum of GC calibrated species. The BTX concentration obtained by means of adsorption with activated carbon test tubes did neither match values from SPA nor DIN CEN/TS 15439 analysis. Moreover, the upper limit of the third quartile of a boxplot of SPA values coincides well with the arithmetic average of the DIN CEN/TS 15439 analysis. This underlines that SPA method offers potential for tar analysis in a similar manner as DIN CEN/TS 15439
