Social Media as a Mean for Improved Technical Communication

Technical communication (TC) is an important activity in order to provide the users of technical artifacts with necessary information concerning the operation and maintenance of the products they are using. In the current working procedures of TC, however, the users become too passive. They are just receivers of information. Further, there is no effective feedback from the users to the producers of the information. In order to overcome those problems we here propose an application of social media (SM) in future TC. By using SM as a complementary channel for TC it becomes possible for technology firms to boost their competitive advantage and to improve the quality and completeness of their TC. This technique, however, is still more of a potential and less of a reality. Several problems, mostly concerning security and confidentiality remain to be solved. The empirical base for this work comes from TIC, an EU-funded development project involving several Swedish technology companies. Published research results are somewhat scattered but several sources coherently indicate both the need and potential for SM as a vehicle in TC. By scanning the net it is further possible to identify a number of seemingly successful applications of SM in such applications.     

Living systems applications in Sweden

The paper discusses Swedish experiences of applying living systems theory within geoInformatics, urban management, rescue systems, software engineering, and modeling. In assessing these experiences it is found that a sound base has been established but that further development and research are needed. Finally, three current projects for making the theory more operational are briefly presented.     

Uncharted secretory nerves in the parotid gland of the dog

Zusammenfassung Es wird in Versuchen an Hunden gezeigt, dass man nach Durchschneidung und Degeneration des Nervus auriculotemporalis reflektorisch eine beachtliche Parotissekretion auslösen kann. Histochemisch konnten zudem viele acetylcholinesterasepositive Nerven nachgewiesen werden.

Taming tempests through telegraphy and media appearances: Science communication and the construction of a Swedish storm-warning system before the Great War

The aim of this paper is to explore relations between science and the public. Specifically, Swedish meteorology around 1900 and the rôle of media relations in the construction of a storm-warning system will be discussed. It is argued that science–public interaction can be a factor in the process of establishing priorities in science.     

Some characteristics of urokinase released in organ culture of human kidney.

Plasminogen activator produced in organ culture of human kidney, i.e. in the histotypical arrangement of the tissue, was partially purified by affinity chromatography on para-aminobenzamidine coupled to Sepharose by a 6-carbon spacer, followed by gel chromatography on Sephadex G-100. The molecular weight of 2 active peaks were 27,000 and 52,000 daltons respectively. It was inhibited by DFP and by IgG antiurokinase.     

Improved molecular replacement by density- and energy-guided protein structure optimization

Molecular replacement procedures, which search for placements of a starting model within the crystallographic unit cell that best account for the measured diffraction amplitudes, followed by automatic chain tracing methods, have allowed the rapid solution of large numbers of protein crystal structures. Despite extensive work, molecular replacement or the subsequent rebuilding usually fail with more divergent starting models based on remote homologues with less than 30% sequence identity. Here we show that this limitation can be substantially reduced by combining algorithms for protein structure modelling with those developed for crystallographic structure determination. An approach integrating Rosetta structure modelling with Autobuild chain tracing yielded high-resolution structures for 8 of 13 X-ray diffraction data sets that could not be solved in the laboratories of expert crystallographers and that remained unsolved after application of an extensive array of alternative approaches. We estimate that the new method should allow rapid structure determination without experimental phase information for over half the cases where current methods fail, given diffraction data sets of better than 3.2?? resolution, four or fewer copies in the asymmetric unit, and the availability of structures of homologous proteins with >20% sequence identity.
