Hemerobiebewertung der Waldökosysteme im Wiener Anteil des Nationalpark Donau-Auen

Die vorliegende Hemerobiestudie der Waldökosysteme im Wiener Anteil der Lobau 2011 ist Teil des MaB-Projektes „Perspektive Lobau 2020“. Die neuentstehenden Siedlungsgebiete am Rande der Lobau (z.b. „Seestadt Aspern“) und die verbesserte Verkehrsanbindung des Gebietes bis 2020 werden den Besucherdruck im Nationalparkgebiet deutlich erhöhen und stellen somit automatisch eine potentielle Gefährdung des Schutzgebietes dar. Um diesen Gefahren frühzeitig entgegen zu treten, wurden wissenschaftliche Studien in Auftrag gegeben, welche verschiedenste Perspektiven der Lobau untersuchen sollten. Im Zuge der Hemerobieerhebung (2011) wurde der jetzige Kultureinfluss auf das Untersuchungsgebiet der Lobau in Form der „Hemerobie“ festgehalten. Die Beurteilung der im Freiland erhobenen Kriterien orientierte sich vorwiegend an der Studie „Hemerobie Österreichischer Waldökosysteme“ von GRABHERR et al. 1998. Für die Analyse der Hemerobie wurden auf 39 Stichprobeflächen, unterschiedlicher Waldbiotope, umfangreiche Erhebungen der Vegetation und eine genaue Dokumentation der Hemerobiekriterien durchgeführt. Die Interpolation der Ergebnisse in die Fläche ergab für einen überwiegenden Anteil der Waldflächen im Untersuchungsgebiet (~ 80%) eine Einstufung der Hemerobie als »alpha-oligohemerob«. Für rund 4% der Flächen resultierte eine Zuordnung zu der Klasse »beta-mesohemerob – alpha-oligohemerob«. Rund 7% werden demnach der Hemerobiestufe »beta-mesohemerob« und ~4% der Hemerobiestufe »alpha-mesohemerob« zugeteilt

Dichotomy theorems for random matrices and closed ideals of operators on (\bigoplus_{n=1}^\infty\ell_1^n)_{c_0}.

We prove two dichotomy theorems about sequences of operators into L_1 given by random matrices. In the second theorem we assume that the entries of each random matrix form a sequence of independent, symmetric random variables. Then the corresponding sequence of operators either uniformly factor the identity operators on l_1^k for k = 1,2, ..., or uniformly approximately factor through c_0. The first theorem has a slightly weaker conclusion still related to factorization properties but makes no assumption on the random matrices. Indeed, it applies to operators defined on an arbitrary sequence of Banach spaces. These results provide information on the closed ideal structure of the Banach algebra of all operators on the c_0-direct sum of the finite-dimensional l_1-spaces l_1^1, l_1^2,..., l_1^n,..

Coefficient Quantization for Frames in Banach Spaces

Let $(e_i)$ be a fundamental system of a Banach space. We consider the problem of approximating linear combinations of elements of this system by linear combinations using quantized coefficients. We will concentrate on systems which are possibly redundant. Our model for this situation will be frames in Banach spaces.Comment: 33 page

Language re-discovered: A death education intervention in the net between kindergarten, family and territory

The article presents the positive results of a death education experience, realized owing to a collaboration between school, family and territory. The project, with the scope of reflecting on topics of death and spirituality, included 46 children of 5 from kindergarten and 50 parents, and then mobilizing the entire community. Social services and public administration had a special role in this, aiming to guarantee the necessary support for the families in the existential reflections. The experience was monitored with participatory observation, via interviews and questionnaires. The children answered questions regarding death and spirituality during an open and sincere conversation with the teachers. The parents, who at home talked about certain pre-defined teams with the children, were asked to give their informed consent and were given a questionnaire with open questions ex-ante/ ex-post. All data were processed via qualitative analysis of the texts. The results are truly positive, showing that children are capable of facing the problem of death and are able to acquire a certain representation of the spiritual dimension. The parents, who in the beginning demonstrated some anxiety, eventually were greatly satisfied and expressed their willingness to continue to search for the connection between death and transcendence

The Genome of Camelpox Virus

AbstractCamelpox virus (CMLV), a member of the Orthopoxvirus genus in the Poxviridae, is the etiologic agent of a disease of camels. Here we report the CMLV genomic sequence with analysis. The 205,719-bp CMLV genome contains 211 putative genes and consists of a central region bound by identical inverted terminal repeats of approximately 7 kb. A high degree of similarity in gene order, gene content, and amino acid composition in the region located between CMLV017 and CMLV184 (average 96% amino acid identity to vaccinia virus (VACV)) indicates a close structural and functional relationship between CMLV and other known orthopoxviruses (OPVs). Notably, CMLV contains a unique region of approximately 3 kb, which encodes three ORFs (CMLV185, CMLV186, CMLV187) absent in other OPVs. These ORFs are most similar to B22R homologues found in other chordopoxvirus genera. Among OPVs, CMLV is the most closely related to variola virus (VARV), sharing all genes involved in basic replicative functions and the majority of genes involved in other host-related functions. Differences between CMLV and VARV include deletion and disruption of a large number of genes. Twenty-seven CMLV ORFs are absent in VARV, including seven full-length homologues of NMDA-like receptor, phospholipase D, Schlafen, MT-4 virulence, kelch, VACV C8L, and cowpox (CPXV) B21R proteins. Thirty-eight CMLV ORFs, some of which are fragments of larger genes, differ in size from corresponding VARV ORFs by more than 10% (amino acids). Genome structure and phylogenetic analysis of DNA sequences for all ORFs indicate that CMLV is clearly distinct from VARV and VACV and, as it has been suggested for VARV, it may have originated from a CPXV virus-like ancestor
