Reinhold Reith, Umweltgeschichte in der Frühen Neuzeit
No full textEn Allemagne comme dans les pays anglo-saxons, les questions environnementales sont depuis les années 1980 devenues un thème majeur de la recherche historique. Cet essor des travaux, dans des directions multiformes et selon des approches extrêmement variables, suscite la parution de synthèses, destinées entre autres à un public étudiant, faisant le point des connaissances et débats historiographiques. C’est l’objectif que s’est fixé R. Reith, suivant la tripartition habituelle de la collectio..
Anatase nanoparticles on supergene platinum-palladium aggregates from Brazil: Titanium mobility in natural waters
No full textSupergene aggregates of platinum-palladium (Pt-Pd) intermetallic compounds from the Córrego Bom Sucesso alluvial deposit, Minas Gerais, Brazil, are coated with abundant, poorly crystalline nanoparticles of anatase (TiO2). The anatase coating is widespread, suggesting that the surface of the Pt-Pd grains catalytically destabilised Ti, which was likely dissolved by organic ligands in the ground waters. Association of TiO2 nanocrystallites with organic matter further suggests that biogenic processes could have mediated their formation. These anatase-coated Pt-Pd grains demonstrate an unexpected Ti mobility in supergene environments. © 2012 Elsevier B.V.Alexandre Raphael Cabral, Frank Reith, Bernd Lehmann, Joël Brugger, Guido Meinhold, Miguel Tupinambá, Rogerio Kwitko-Ribeir

Trust and Trustworthiness in the Fourth and Fifth Estates
No full textThe high contemporary salience in the social sciences of the topics of "trust" and "trustworthiness" has focused attention on the mass media’s putative role in eroding trust. Intrinsically, the absence in the mass media of the dialogic and interactive element to trust building identified by O’ Neill (2002) may suggest that the lack of trust and trustworthiness in the mass media is structural and recent penalties imposed by the UK communication regulator, Ofcom, on UK public service broadcasters including the BBC seem to support such a view. However, drawing on and adapting O’Neill, the author identifies two distinct potential media trust building strategies: one procedural (based in professional norms) and the second dialogic and interactive (nascent in “Web 2.0” applications). Focusing on UK Web 2.0 media sites the author identifies instances where the "dialogic" character of "Web 2.0" has established and enhanced trustworthiness. He argues normatively for a combination of "Web 2.0" interactivity and the adoption and implementation of self-regulatory codes in order to enhance the trustworthiness of the media

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
