Stratigraphische Begriffe für das Quartär des süddeutschen Alpenvorlandes
No full textSchwerpunkt der Darstellung über das Quartär des süddeutschen Alpenvorlandes sind die Begriffe der klassischen Morphostratigraphie sensu PENCK & BRÜCKNER (1901/09), methodisch eingeleitet und im Einzelnen ausgearbeitet durch K.A. HABBE. Diese Definitionen entsprechen dem Gebrauch der Begrifflichkeiten in der süddeutschen Quartärliteratur vor allem der Jahre 1950 bis 2000. Die von K.A. HABBE († 2003) hinterlassenen Manuskripte wurden von D. ELLWANGER redaktionell überarbeitet sowie die Definitionen durch Bemerkungen ergänzt und kommentiert (D. ELLWANGER und R. BECKERHAUMANN). Im Anschluss an die Definitionen werden von D. ELLWANGER die morphostratigraphischen Darstellungen aus einem lithostratigraphischen Blickwinkel ergänzend kommentiert, die Problematik Morpho- versus Lithostratigraphie umrissen und schließlich die wichtigsten lithostratigraphischen Begriffe dargestellt, die sich im quartärgeologischen Alltag in Baden-Württemberg seit einigen Jahren bewährt haben. Das gesamte Manuskript wurde sodann durch die Arbeitsgruppe Süddeutschland der Subkommission für Quartärstratigraphie im Einzelnen geprüft und ergänzt. Eine vollständigere Darstellung der lithostratigraphischen Einheiten wird im – in Arbeit befindlichen – Lithostratigraphischen Lexikon erfolgen.researc
Excess pore pressure redistribution beneath pipelines: FEA investigation and effects on axial pipe-soil interaction
No full textThermal expansion of seabed pipelinesmay generate excess pore pressure in the surrounding soil. This paper discusses aspects of the excess pore pressure redistribution process and their effects on the effective stresses at pipe-soil interface, and the resulting soil resistance to pipeline axial movement. The discussion is supported by results of finite element analyses using coupled soil models, which allow pore pressure generation, redistribution and dissipation. A first model provides insight into the two-dimensionality of the redistribution process, illustrating why dissipation rates differ from one-dimensional consolidation processes.A second model is used to addresses the effect of (apparent) over-consolidation local to the pipe-soil interface. This provides a plausible explanation for the observation in model tests of positive excess pore pressure in initially dilatant soil at the pipe interface.</p
Liberdade de Expressão e Discurso do Ódio: uma análise da jurisprudência norte-americana e brasileira
No full textTCC(graduação) - Universidade Federal de Santa Catarina. Centro de Ciências Jurídicas. Direito.O presente trabalho versa sobre a relação entre a liberdade de expressão e o discurso do ódio e como o assunto é tratado no direito norte-americano e no direito brasileiro. A análise do tema baseia-se no estudo da previsão constitucional acerca da liberdade de expressão em ambos os ordenamentos jurídicos e no estudo da jurisprudência dominante de cada país a respeito da liberdade de expressão em relação ao discurso do ódio. Primeiramente trata-se do contexto norte-americano: a liberdade de expressão como prevista na Primeira Emenda à Constituição dos Estados Unidos, as principais decisões da Suprema Corte envolvendo o assunto e o estudo do caso Brandenburg v. Ohio. Passa-se então à análise do contexto brasileiro: a liberdade de expressão na Constituição de 1988 e o estudo do habeas corpus 82.424/RS (STF). Por fim, trata-se da relação entre o discurso do ódio e a igualdade e dignidade, e dos aspectos distintivos do caso Brandenburg v. Ohio – EUA –, e do caso Ellwanger (habeas corpus 82.424/RS) – Brasil
A novel approach for time-dependent axial soil resistance in the analysis of subsea pipelines
No full textA novel approach for modelling axial pipe–soil interaction, consisting of bespoke finite elements, is proposed. The purpose is to have a model that represents a two-dimensional slice of soil perpendicular to the pipe which is computationally cheap enough to be incorporated in global analysis of subsea pipelines, whilst capable of capturing detailed time-dependent soil response, which involves partial drainage and cyclic plasticity. This is achieved by handling the circumferential dimension analytically, reducing the behaviour of the two-dimensional soil slice to a one-dimensional case. Coupled consolidation analysis along a vertical sequence of one-dimensional elements beneath each pipeline node, tailored to represent the axial–vertical (or -radial) plane across the seabed semi-space, is supplemented by an analytical solution for the circumferential drainage. The paper presents the model development, its implementation through symbolic programming and validation against previously published continuum finite element analysis results
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
