Rollen von pädagogischen Fachkräften und Erziehungspersonen in gemeinsamen Literacy Aktivitäten in Kitas in Luxemburg
No full textIn Luxemburg sind die Sprachen Luxemburgisch, Französisch und Deutsch offizielle Landessprachen. Seit 2017 soll die luxemburgische Mehrsprachigkeit durch das Programm der „éducation plurilingue“ entscheidende Impulse in Bildungseinrichtungen für ein- bis vierjährige Kinder erhalten. So müssen z. B. alle pädagogischen Fachkräfte vielfältige Literacy Aktivitäten anbieten und mit den Erziehungspersonen kooperieren (Kirsch 2021).
Obwohl ein breiter Konsens besteht, dass eine gute Zusammenarbeit zwischen Eltern bzw. Erziehungspersonen und pädagogischen Fachkräften in Kindertageseinrichtungen (Kitas) positive Auswirkungen auf die Kinder, Erziehungspersonen und pädagogischen Fachkräfte hat und dass frühe Literacy Erfahrungen in mehreren Sprachen zur Entwicklung der Sprach- und Lesekompetenz beitragen können (Sheridan et al. 2011; Zucker et al. 2021), gibt es nur wenige Studien zu Literacy Aktivitäten in Kitas, an denen pädagogische Fachkräfte und Erziehungspersonen gemeinsam teilnehmen. Erste Einblicke in die Rollen der pädagogischen Fachkräfte und Erziehungspersonen in gemeinsamen Aktivitäten liefert die Studie „Collaboration with parents and development of literacies“ (COMPARE) in Luxemburg.
Der Beitrag untersucht die Rollen der Erziehungspersonen und der pädagogischen Fachkräfte in gemeinsamen Vorleseinteraktionen in zwei Kitas. Die Daten stammen von Interviews und Beobachtungen, die im akademischen Jahr 2020-21 erhoben und mittels einer Konversations- und Themenanalyse ausgewertet wurden. Alle beobachteten Erziehungspersonen lasen Geschichten in ihrer Familiensprache; allerdings benutzten die Erziehungspersonen in einer der beiden Kitas in den Interaktionen ebenfalls Luxemburgisch für die literarischen Gespräche mit den Kindern und Erziehungspersonen. Die Rollen der Erziehungspersonen (Teilnehmende, Beobachtende, Zuschauende) waren von hierarchischen Beziehungen geprägt und hingen mit dem Verständnis von Literacy der pädagogischen Fachkräfte sowie dem Ziel der Bildungspartnerschaft zusammen. Die Ergebnisse der Studie zeigen wichtige Themen für Weiterbildungsmaßnahmen auf.

Structure of ACC synthase inactivated by the mechanism-based inhibitor l-vinylglycine
No full textAbstractl-Vinylglycine (l-VG) is both a substrate for and a mechanism-based inhibitor of 1-aminocyclopropane-1-carboxylate (ACC) synthase. The ratio of the rate constants for catalytic conversion to α-ketobutyrate and ammonia to inactivation is 500/1. The crystal structure of the covalent adduct of the inactivated enzyme was determined at 2.25Å resolution. The active site contains an external aldimine of the adduct of l-VG with the pyridoxal 5′-phosphate cofactor. The side chain γ-carbon of l-VG is covalently bound to the ε-amino group of Lys273. This species corresponds to one of the two alternatives proposed by Feng and Kirsch [Feng, L. and Kirsch, J.F. (2000) l-Vinylglycine is an alternative substrate as well as a mechanism-based inhibitor of 1-aminocyclopropane-1-carboxylate synthase. Biochemistry 39, 2436–2444] and presumably results from Michael addition to a vinylglycine ketimine intermediate

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
