L'étymologie portugaise selon John Minsheu (1617)
No full textDans le cadre de nos travaux sur I'évolution du lexique portugais (v. "Dictionnaire chronologique portugais" 1976; "História do léxico português" 1990) nous avons commencé non seulement à analyser les périodiques portugais entre 1700 et 1850 (v. Messner/Aglassinger 1992) sinon aussi à réunir des oeuvres lexicographiques anciennes. Nous espérons pouvoir publier un jour un "dictionnaire des dictionnaires portu gais" (c'est pour l'espagnol qu'existe une telle oeuvre, restée malheureusement fragmentaire: le "Tesoro lexicográfico" de Samuel Gili Gaya, Madrid 1947-1952). Dans Jes "Beihefte" de Lusorama (Messner 1993), nous publierons un échantillon qui embrasse l'espace de temps limité par la publication du dictionnaire de Rafael Bluteau en 1712 ("Vocabulario Portuguez et Latino, etc., autorizado com exemplos dos me lhores escritores portuguezes, e latinos, e offerecido a El Rey de Portugal, D. João V pelo Padre D. Rafael Bluteau, Coimbra 1712") et la 6e édition du dictionnaire de Antonio de Moraes Silva en 1858 (Diccionario da Lingua Portugueza composto por de Moraes Silva, Lisboa 1858.)

National flood damage evaluation methods: A review of applied methods in England, the Netherlands, the Czech Republik and Germany
No full textThe focus of this guidance document is decision making under uncertainty in river basin management. Our purpose is to give hints for the analysis of decision situations in the HarmoniRiB case studies. The background of HarmoniRiB and thus of the case studies is the implementation of the EU-Water Framework Directive. The directive states the goal that all waters3 in the EU should reach a good status4 by 20155. In order to achieve this goal the member states need to set up river basin districts, each one having a management plan that includes a programme of measures which will achieve good status in the most costeffective manner. We conceptualize this management problem as a decision problem: Which measures should be selected for the programme of measures? The HarmoniRiB case studies are not able to cover all problems of the implementation of the EU-Water Framework Directive in all their complexity. They only investigate certain aspects of this problem. Therefore, we concentrate in this guidance document on a certain type of decision, the selection of management measures to reach a certain goal (this would usually be good status) for the case study river basins. Thereby we put a special focus on uncertainties. --
The s-layer glycome-adding to the sugar coat of bacteria
No full textThis work was supported by the Austrian Science Fund FWF, projects P19047-B12, P20605-B12, P21954-B20 (to C. Sch¨affer), and P20745-B11 (to P. Messner). Zarschler and Ristl were supported by the Hochschuljubil¨aumsstiftung der Stadt Wien, Projects H-2229-2007 (to K. Zarschler) and H-1897-2008 (to R. Ristl).The amazing repertoire of glycoconjugates present on bacterial cell surfaces includes lipopolysaccharides, capsular polysaccharides, lipooligosaccharides, exopolysaccharides, and glycoproteins. While the former are constituents of Gram-negative cells, we review here the cell surface S-layer glycoproteins of Gram-positive bacteria. S-layer glycoproteins have the unique feature of self-assembling into 2D lattices providing a display matrix for glycans with periodicity at the nanometer scale. Typically, bacterial S-layer glycans are O-glycosidically linked to serine, threonine, or tyrosine residues, and they rely on a much wider variety of constituents, glycosidic linkage types, and structures than their eukaryotic counterparts. As the S-layer glycome of several bacteria is unravelling, a picture of how S-layer glycoproteins are biosynthesized is evolving. X-ray crystallography experiments allowed first insights into the catalysis mechanism of selected enzymes. In the future, it will be exciting to fully exploit the S-layer glycome for glycoengineering purposes and to link it to the bacterial interactome.Peer reviewe

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
