Dave and Dottie Seibold : founding members of the Grand Haven Area Historical Society
No full textGrand Haven historian, author, and dentist Dave Seibold has a passionate interest in community heritage. Prior to relocating to Grand Haven, Dr. Seibold served in Hawaii at a dental clinic for children. In this interview, Dr. Seibold and his wife Dottie discuss the founding of the Grand Haven Area Historical Society, which began its existence as the Tri-Cities Historical Society in 1959, and the Tri-Cities Historical Museum. Dr. Seibold explains the efforts to save the Grand Haven railroad depot from demolition for possible use as a museum and his project to write a history of northern Ottawa County to continue the work of historian Leo C. Lillie. In 1990, Dr. Seibold authored and published Coast Guard City, U.S.A: A History of the Port of Grand Haven. The Seibolds also recall how they met in their hometown of Jackson, Michigan, married, and chose Grand Haven as their home in 1955

Das Forschungsschiff "Meteor" im ibero-marokkanischen Seegebiet [M8]
No full textDie "Meteor" befindet sich zur Zeit auf der zweiten ihrer Kuppenfahrten im östlichen Atlantik. Über den ersten Fahrtabschnitt vom 11. Januar bis 7. März 1967 berichtet Prof. Dr. Eugen Seibold, Direktor des Geologischen Instituts der Universität Kiel, der diesen Teil der Expedition leitete.
Im ersten Teil der "Atlantischen Kuppenfahrten 1967", auf der Fahrt "Meteor 8", stand der Kontinentalrand vor Portugal und Marokko im Vordergrund des wissenschaftlichen Interesses

No full textImproving author co-citation analysis in scientific literature by using citation function classification
No full textThe concept of co-citation analysis is a possible approach for the interpretation of the relations between scientific papers or authors. Most of the previous work regarding author co-citation analysis, however, does not take the citation context into account. In this thesis, I propose a method for letting citation functions, which are functions that represent the intention of an author assigned to the corresponding references, directly influence the author co-citation analysis procedure. This approach is based on a faceted citation classification scheme, which allows comparisons between references. This should allow an easier representation of author groups, as authors, which are working together, usually share the same view on science and, therefore, are likely to be cited similarly. As there is no real gold standard for author groups, the evaluation of this approach tests the textual coherence of clusters created by this procedure based on the authors' oeuvres and compares the nationality of authors within clusters. The results indicate a correlation between author groups and similar citation functions.Die Thematik der Co-Zitation Analyse beschreibt einen möglichen generellen Ansatz zur Interpretation von Beziehungen zwischen einer Menge von wissenschaftlichen Arbeiten oder Autoren. Die meisten Methoden zur Erstellung von Autorenclustern, die bisher zu diesem Themengebiet vorgestellt wurden, nehmen keinen Bezug auf den Kontext, in welchem die jeweiligen Zitationen vorkommen. In dieser Arbeit stelle ich eine Möglichkeit vor, durch die Zitationsfunktionen direkten Einfluss auf Autorcozitationsanalyse nehmen kann. Eine Zitationsfunktion gibt die Intention des Autors wieder, welche zu einer Referenz geführt hat, und ist somit an diese Referenz gebunden. Der hier vorgestellte Vorgang bezieht sich auf eine facettiertes Zitationsklassifikationsschema, durch welches Referenzen verglichen werden können. Dies sollte eine einfachere Möglichkeit darbieten Autorengruppen darzustellen, da diese, dadurch dass sie ähnliche Ansichtspunkte auf ihre Fachgebiete haben, auf ähnliche Art und Weise zitiert werden. Da es keinen richtigen Goldstandard für Autorengruppen gibt, bezieht sich die Evaluation auf den textbezogenen Zusammenhang zwischen den Oeuvres von Autoren und die Repräsentation von Nationalitäten innerhalb von Clustern. Die Resultate, die in dieser Arbeit gefunden werden, deuten darauf hin, dass es tatsächlich einen Zusammenhang zwischen Authorengruppen und ähnlichen Zitierweisen dieser Autoren gibt
Particle-particle response function as a probe for electronic correlations in the p-d Hubbard model
No full textWe discuss and compare different approximations to the particle-particle response function in the p-d (three-band) Hubbard model for the CuO2 plane of superconducting cuprates. Besides the relevance for understanding the role of correlations in high-Tc superconductors, the interest in the CuO2 plane is due to the presence of three incompletely filled valence bands. The bare ladder approximation (BLA) was employed long ago in the context of Auger core-valence-valence spectroscopy of late transition metals while the time-dependent (TD) Gutzwiller approximation (GA) is a much more sophisticated and recent development. The validity of both is assessed by comparing with exact-diagonalization results from a finite six-site cluster. We find that for standard parameter sets TDGA and BLA yield two-hole spectra in excellent agreement with the exact ones. Although the interaction is comparable to the kinetic energy, the system is far from the extreme Mott limit often assumed in cuprates, where the Mott insulating character is completely local. In order to identify possible fingerprints of the extreme Mott regime we artificially reduce the bandwidth. We find that the BLA breaks down while the TDGA keeps near the exact results. Our findings provide a simple criterion to identify doped and undoped extreme Mott insulators
Phonon renormalization from local and transitive electron-lattice couplings in strongly correlated systems
No full textWithin the time-dependent Gutzwiller approximation applied to one-dimensional Holstein and Su-Schrieffer-Heeger-Hubbard models, we study the influence of electron correlations on the phonon self-energy. For the local Holstein coupling, we find that the phonon-frequency renormalization gets weakened upon increasing the on-site interaction U for all momenta. In contrast, correlations can enhance the phonon-frequency shift for small wave vectors in the Su-Schrieffer-Heeger-Hubbard model. Moreover, the time-dependent Gutzwiller approximation applied to the latter model provides a mechanism which leads to phonon-frequency corrections at intermediate momenta due to the coupling with double-occupancy fluctuations. Both models display a shift of the nesting induced to a q=0 instability when the on-site interaction becomes sufficiently strong and thus establishing phase separation as a generic phenomenon of strongly correlated electron-phonon coupled systems
Let's Twist Again : Was man nicht denken kann, das soll man tanzen : Performance in Wien von 1960 bis heute : Eine psychogeografische Skizze = If You Can't Think It, Dance It : Performance in Vienna from 1960 until today : A psychogeographical map
No full text"Based on the exhibition 'let's twist again', which we organized in 2002, this book documents local and international performance-works in Vienna since 1960. Of particular interest for us are the works by artists who, despite their importance for the 'scene', have been ignored by the official historiographies or remained largely unknown. We have put emphasis on performances that deal with feminism and gender-related themes, for in our opinion, regarding the significance of performance today, these issues seem to be particularly relevant." -- Cover of document
