Neue Fossilien aus dem Hochgebirge Graubündens
Seit 1997 führt ein kleines, hoch motiviertes Team der Universität Zürich unter Leitung von Heinz Furrer, dem Autor dieses Berichts, auf mehr als 2700 Meter über Meer im Ducangebiet zwischen Davos und Bergün GR systematische Fossiliengrabungen in Sedimentgesteinen der mittleren Trias durch. Dabei wurden in 241 Millionen Jahre alten Meeresablagerungen der mittleren Trias viele ausgezeichnet erhaltene Fossilien gefunden, die mit denjenigen der klassischen Fundstelle des Monte San Giorgio im Südtessin vergleichbar sind. Die meisten Versteinerungen stammen von kleinen urtümlichen Knochenfischen mit Schmelzschuppen, aber auch bis zu 1 m lange Raubfische konnten vollständig geborgen werden. Dazu kamen seltenere Reste von meer- und landbewohnenden Sauriern, von Krebsen, Muscheln, Schnecken, Kalkalgen und Landpflanzen
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Emergence of Klebsiella pneumoniae co-producing NDM-1, OXA-48, CTX-M-15, CMY-16, QnrA and ArmA in Switzerland
Extensively drug-resistant (XDR) Klebsiella pneumoniae isolates usually carry a single carbapenemase (e.g. KPC, NDM, OXA-48-like). Here we describe an XDR K. pneumoniae of sequence type 101 that was detected in the screening rectal swab of a patient transferred from the intensive care unit of a hospital located in Belgrade (Serbia) to Bern University Hospital (Switzerland). The isolate was resistant to all antibiotics with the exception of colistin [minimum inhibitory concentration] (MIC≤0.125μg/mL), tigecycline (MIC=0.5μg/mL) and fosfomycin (MIC=2μg/mL). The isolate co-possessed class B (NDM-1) and class D (OXA-48) carbapenemases, class A extended-spectrum β-lactamase (CTX-M-15), class C cephalosporinase (CMY-16), ArmA 16S rRNA methyltransferase, substitutions in GyrA and ParC, loss of OmpK35 porin, as well as other genes conferring resistance to quinolones (qnrA), tetracyclines [tet(A)], sulfonamides (sul1, sul2), trimethoprim (dfrA12, dfrA14), rifampicin (arr-1), chloramphenicol (cmlA1, floR) and streptomycin (aadA1). The patient was placed under contact isolation precautions preventing the spread of this nearly untreatable pathogen
Revised paleoecology of placodonts – with a comment on ‘The shallow marine placodontCyamodus of the central European Germanic Basin: its evolution, paleobiogeography and paleoecology’ by C.G. Diedrich
A recent article published by Diedrich (2011a, Hist Biol. iFirst online, 1–19, doi: 10.1080/08912963.2011.575938) aspired
to provide a complete revision of the known material of the placodont genus Cyamodus Meyer, 1863 from the Germanic
Basin of central Europe. It is the latest in a series of similar articles by the same author (see Diedrich 2010, Palaeogeogr
Palaeoclimatol Palaeoecol. 285(3–4):287–306; 2011b, Nat Sci. 3(1):9–27 for overview) focussing on the European
members of the Placodontia (Reptilia: Sauropterygia), a diverse group of enigmatic marine reptiles known from Triassic
shallow marine deposits. In a similar fashion to some previous works by Diedrich (see Tintori 2011, Palaeogeogr
Palaeoclimatol Palaeoecol. 300(1–4):205–207 for similar points of criticism), this newest article demonstrates a narrow
scope of presenting and discussing data, including omitted articles relevant to the topic, and over-interpretation of results, all
with the aim of embedding the idea of placodonts being herbivorous Triassic ‘sea cows’ feeding on macroalgae (Diedrich
2010, 2011b). The present contribution is intended to clarify mistakes and misinterpretations made by Diedrich (2011a), to
incorporate vital citations previously omitted which allow alternative interpretations, and to put the paper into perspective by
including a more general evolutionary and paleoecological overview of the remaining placodonts
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
