Richard Serra ( born November 2, 1938) is an American minimalist sculptor and video artist known for working with large - scale assemblies of sheet metal . [1] Serra was involved in the Process Art Movement. He lives and works in Tribeca , New York , and on Cape Breton Island in Nova Scotia . Serra had his first solo exhibitions at the Galleria La Salita, Rome, 1966, and in the United States at the Leo Castelli Warehouse, New York. The Pasadena Art Museum organized a solo exhibition of Serra’s work in 1970. Serra has since participated in Documentas 5 (1972), 6 (1977), 7 (1982), and 8 (1987), in Kassel, the Venice Biennales of 1984 and 2001, and the Whitney Museum of American Art's Annual and Biennial exhibitions of 1968, 1970, 1973, 1977, 1979, 1981, and 19 95.[57] Serra was honored with further solo exhibitions at the Kunsthalle Tübingen, Germany, in 1978; the Musée National d'Art Moderne, Paris, in 1984; the Museum Haus Lange, Krefeld, Germany, in 1985; and the Museum of Modern Art, New York, in 1986. From 1997 to 1998 his Torqued Ellipses (1997) were exhibited at and acquired by the Dia Center for the Arts, New York. In 2005 eight major works by Serra were installed permanently at Guggenheim Museum Bilbao. In the summer of 2007 the Museum of Modern Art pre sented a retrospective of Serra's work in New Y ork. Intersection II (1992 – 1993) and Torqued Ellipse IV (1998) were included in this show along with three new works.[59] The retrospective consisted of 27 of Serra's works, including three large new sculpture s made specifically for the second floor of the museum, two works in the garden, and Yearlier pieces from the 1960s through the 1980s

Dieses Buch bietet eine grundlegende Einführung in den Einsatz der Methode des Decision Theater zur Vermittlung von mathematischer Modellierungskompetenz im Schulkontext. In den letzten Jahren hat sich unter anderem anhand der Covid-19 Pandemie mehr denn je gezeigt, wie Mathematik im Allgemeinen und das mathematische Modellieren im Speziellen zum Verständnis globaler Herausforderungen und Möglichkeiten zu ihrer Bewältigung beiträgt. Deshalb sollte die mathematische Modellierungskompetenz eine zentrale Rolle im Schulunterricht spielen. Doch der Prozess von Vermittlung und Erwerb einer solchen Kompetenz ist komplex und mit vielfältigen Schwierigkeiten verbunden. Angesichts dieser Ausgangslage stellt das Buch die Methode des Decision Theater als innovative Lernumgebung neuer Art vor, die die Vermittlung von mathematischer Modellierungskompetenz unterstützen kann. Dabei trägt die Methode des Decision Theatre auf drei Ebenen dazu beiträgt, Modellierungskompetenz und ein damit verbundenes ganzheitliches Bild der Mathematik zu fördern: Das Decision Theatre dient als IT-Dienstleister, als Wissenschaftskommunikator und als interaktiv-diskursive Lernumgebung. Neben Geschichte und Definition des Decision Theater, stellt das Buch dessen Einsatz konkret am Beispiel des Projekts „Schule @ Decision Theatre Lab“ des Berliner Exzellenzclusters MATH+ Berlin Mathematics Research Center vor. Als Zusammenfassung der wichtigsten Aspekte des Einsatzes der Methode des Decision Theater im Schulkontext richtet sich das Buch an Didaktiker*innen und Lehrkräfte aller Schulformen.

Alexander Rhode investigates performance-oriented measures of Contracting Authorities in public tenders conducted within the EU. He finds that Contracting Authorities can improve their performance and attract more suppliers by publishing (as precise as possible) starting prices in the beginning of a tender. First, he reports that compared with private-sector negotiations, starting prices do not create entry barriers in public procurement. Second, he finds that increased numerical precision of starting prices is linearly correlated with better performance and a higher number of bids. In public procurement, suppliers tend to attribute increased credibility to precise starting prices which reduces their (perceived) entry risks.
