Visualized Collective Memories: Social Representations of History in Images Found in Finnish History Textbooks
Authors: Hakoköngäs Eemeli , Sakki Inari 
Published: May 2016

AbstractThis study focuses on visual collective memory, a topic that has long been neglected in the social sciences and particularly in social psychological research on social representations of history. It explores the contents and meanings of images in the construction of Finnish national history. Through examination of official history writing, a better understanding is sought of how collective memory is constructed as part of history politics. The data for the present study consist of images (N = 541) included in recent textbooks on Finnish history. Barthes' three‐meaning approach is used in combination with qualitative content analysis to examine a large corpus of images. The visualized collective memory is approached from five perspectives: (i) the years of memory; (ii) the places of memory; (iii) the themes of memory; (iv) the main actors and (v) the silence of memory. The investigation shows that, in official discourse, politics, culture and war are the main contents of Finnish visual collective memory. The key actors in the narrative are politicians, especially the eighth president of Finland, Urho Kekkonen. The most important moments in time are situated in the war years 1918 and 1939, while the geographical focus is the central square in the capital, Helsinki. The result is a national history that is positive, homogeneous and exclusive. Copyright © 2016 John Wiley & Sons, Ltd.
Enhanced rig‐space simulation

Published: May 2016

AbstractRig‐space physics a finite element method(FEM) based simulation technique that aims at adding secondary motion on a character while maintaining seamless cooperation with traditional animation pipelines. We enhance the rig‐space physics by introducing several techniques, including general field interaction, proportional‐derivative control, and improved material control. This allows an animator to perform various interferences to the simulation process and create more abundant animation effects. Moreover, we also improve the numerical stability of the simulation algorithm by prepending a conjugate gradient procedure. Copyright © 2016 John Wiley & Sons, Ltd.
(R)‐Selective Nitroaldol Reaction Catalyzed by Metal‐Dependent Bacterial Hydroxynitrile Lyases
Authors: Bekerle‐Bogner Myria , Gruber‐Khadjawi Mandana , Wiltsche Helmar , Wiedner Romana , Schwab Helmut , Steiner Kerstin 
Published: May 2016

AbstractThe nitroaldol (Henry) reaction is a valuable C−C bond‐forming reaction resulting in β‐nitro alcohols, which are important building blocks for the synthesis of bioactive compounds. Metal‐dependent bacterial hydroxynitrile lyases with a cupin fold couple nitromethane or nitroethane and various aldehydes to yield (R)‐β‐nitro alcohols with up to 90 % conversion and up to ≥99 % enantiomeric excess.
Shaping Covalent Triazine Frameworks for the Hydrogenation of Carbon Dioxide to Formic Acid
Authors: Bavykina Anastasiya V. , Rozhko Elena , Goesten Maarten G. , Wezendonk Tim , Seoane Beatriz , Kapteijn Freek , Makkee Michiel , Gascon Jorge 
Published: May 2016

AbstractA facile one‐step method to shape covalent triazine frameworks (CTFs) for catalytic applications is reported. Phase inversion of the CTF powder by using a polyimide as a binder in a microfluidic device results in the formation of composite spheres with accessible CTF porosity and a high mechanical and thermal stability. The fabricated spheres can be used to host organometallic complexes. The obtained shaped catalysts, Ir@CTF spheres, are active and fully recyclable in the direct hydrogenation of carbon dioxide into formic acid under mild reaction conditions (20 bar and 50–90 °C) and in the dehydrogenation of formic acid.
