Linking Data Sovereignty and Data Economy: Arising Areas of Tension

In the emerging information economy, data evolves as an essential asset and personal data in particular is used for data-driven business models. However, companies frequently leverage personal data without considering individuals’ data sovereignty. Therefore, we strive to strengthen individuals’ position in data ecosystems by combining concepts of data sovereignty and data economy. Our research design comprises an approach to design thinking iteratively generating, validating, and refining such concepts. As a result, we identified ten areas of tension that arise when linking data sovereignty and data economy. Subsequently, we propose initial solutions to resolve these tensions and thus contribute to knowledge about the development of fair data ecosystems benefiting both individuals’ sovereignty and companies’ access to data

Untangling the chemical evolution of Titan's atmosphere and surface–from homogeneous to heterogeneous chemistry

The arrival of the Cassini-Huygens probe at Saturn's moon Titan - the only Solar System body besides Earth and Venus with a solid surface and a thick atmosphere with a pressure of 1.4 atm at surface level - in 2004 opened up a new chapter in the history of Solar System exploration. The mission revealed Titan as a world with striking Earth-like landscapes involving hydrocarbon lakes and seas as well as sand dunes and lava-like features interspersed with craters and icy mountains of hitherto unknown chemical composition. The discovery of a dynamic atmosphere and active weather system illustrates further the similarities between Titan and Earth. The aerosol-based haze layers, which give Titan its orange-brownish color, are not only Titan's most prominent optically visible features, but also play a crucial role in determining Titan's thermal structure and chemistry. These smog-like haze layers are thought to be very similar to those that were present in Earth's atmosphere before life developed more than 3.8 billion years ago, absorbing the destructive ultraviolet radiation from the Sun, thus acting as 'prebiotic ozone' to preserve astrobiologically important molecules on Titan. Compared to Earth, Titan's low surface temperature of 94 K and the absence of liquid water preclude the evolution of biological chemistry as we know it. Exactly because of these low temperatures, Titan provides us with a unique prebiotic 'atmospheric laboratory' yielding vital clues - at the frozen stage - on the likely chemical composition of the atmosphere of the primitive Earth. However, the underlying chemical processes, which initiate the haze formation from simple molecules, have been not understood well to date

Gemeinsamer Unterricht am Gemeinsamen Gegenstand: Das Projekt "Jugend inklusive – global engagiert"

[Die Autorinnen] berichten über das Projekt „Jugend inklusive – global engagiert“, das im Rahmen der Dekade „Bildung für eine nachhaltige Entwicklung“ gefördert wird. Im Projekt werden Vorschläge für Ansätze inklusiver Unterrichtsgestaltung entwickelt. Dies erscheint dringend notwendig, da der Inklusionsgedanke bisher selten entsprechend den Vorschlägen der Behindertenrechtskonvention der UNO von 2006 in die Praxis umgesetzt wird. Anstelle von Inklusion werden eher additive Modelle eingeführt, bei denen Schülerinnen und Schüler mit Behinderung zwar in Regelklassen aufgenommen werden, die didaktisch-methodischen Ansätze für den Unterricht aber unverändert bleiben. Da aber der Anspruch auf Inklusion für alle Schülerinnen und Schüler in der Gestaltung der Unterrichts einen Niederschlag finden sollte, war es Ziel des Projekts, neben der Entwicklung von Unterrichtsmaterial die Professionalisierung der Lehrkräfte zu unterstützen, damit sie den steigenden inhaltlichen, pädagogischen und didaktisch methodischen Anforderungen inklusiven Unterrichts in Zukunft besser gerecht werden können.
