No full textDass bereits in frühen Lebensverlaufsphasen soziale Herkunft, Ausländerstatus und Migrationshintergrund mit nachteiligen Bildungschancen einhergehen und weitreichende Konsequenzen für spätere Bildungs- und Berufschancen haben, gehört inzwischen zum Standardwissen in der empirischen Bildungsforschung (Becker und Schubert 2011; Becker 2009a, 2009b; Kalter et al. 2007; Ditton und Krüsken 2006; Ditton et al. 2005; Seibert und Solga 2005; Kalter 2005; Schimpl-Neimanns 2000; Müller und Shavit 1998; Henz und Maas 1995; Müller 1994; Müller und Haun 1994; Blossfeld 1993; Mayer und Blossfeld 1990). Darüber hinaus liegen empirische Evidenzen dafür vor, dass der Einfluss sozialer Herkunft und migrationsbedingter Ressourcen des Elternhauses auf die Lernvoraussetzungen bei der Einschulung und die schulischen Leistungen sowie die darauf basierende Chance, nach der Grundschule für weiterführende Bildung (Realschule oder Gymnasium) empfohlen zu werden, eine wichtige Ursache für Chancenungleichheiten im Bildungssystem zum Nachteil von einheimischen wie zugewanderten Kindern und Jugendlichen aus „bildungsfernen“ Gruppen ist (Biedinger und Becker 2010; Geier und Riedel 2008; Kratzmann und Schneider 2009; Becker und Biedinger 2006; Becker und Lauterbach 2004; Kristen 2002; Boudon 1974)
Schubert Eisenstein series and Poisson summation for Schubert varieties
Get PDFThe first author and Bump defined Schubert Eisenstein series by restricting the summation in a degenerate Eisenstein series to a particular Schubert variety. In the case of over they proved that these Schubert Eisenstein series have meromorphic continuations in all parameters and conjectured the same is true in general. We revisit their conjecture and relate it to the program of Braverman, Kazhdan, Lafforgue, Ngô, and Sakellaridis aimed at establishing generalizations of the Poisson summation formula. We prove the Poisson summation formula for certain schemes closely related to Schubert varieties and use it to refine and establish the conjecture of the first author and Bump in many cases.Accepted by the American Journal of Mathematics.

Get PDFThis paper studies the singularities of affine Schubert varieties in the affine Grassmannian (of type Al⁽¹⁾). For two classes of affine Schubert varieties, we determine the singular loci; and for one class, we also determine explicitly the tangent spaces at singular points. For a general affine Schubert variety, we give partial results on the singular locus.This paper is a contribution to the Special Issue on Kac–Moody Algebras and Applications. The first author was supported by the Swiss National Science Foundation, and partially by an NSERC Discovery Grant. The second author was supported by NSF grant DMS-0652386 and Northeastern University RSDF 07–08. The first author would like to thank the Swiss National Science Foundation for making possible his stay at Northeastern University, during which most of this work has been done.

Franz Schubert - violin pieces
No full textIn this thesis, the author is trying to provide the reader with a general view on life and masterpiece of Franz Schubert, a significant composer of the early 19. century. The first chapter deals with Schubert´s life and important events in his work as well as in personal life. The summary of all his production is to be found in the second chapter, where the author is talking about a chamber production. Other chapters are dedicated to exclusively violin literature and a brief formal analysis of individual music compositions

Agustin Schubert (1902-1942)
No full textAnglická anotace Augustin Schubert (1902-1942) This thesis deals with the life of Augustin Schubert O.S.A., the prior of the Augustinians in St. Thomas monastery, an educator of the Československý Orel and martyr in the Dachau death camp. The Author tries to reconstruct Augustin Schubert's life on detail for which he includes , as far as possible, all available material that can be used for the beatification process of Schubert now undertaken by the Augusinian Order. The first part of this thesis traces the life and activity of Schubert as an Augustinian priest. The second section his work in Československý Orel, the Catholic sport organisation. His contribution to this organisation is important as the author of Orel's Dekalog. His speeches, likewise are important for understanding his thought. The last part of this thesis explains his attitude to Nazism and why he was so dangerosu for the Nazi occupation authorities. For such stand, he was imprisoned and transported to KZ Sachsenhausen an after a few months he was transported to KZ Dachau where he dies on July 27th 1942.
