In response to decreasing oxygen tension, AppA antagonizes the transcriptional regulator PpsR, which represses the expression of photosynthesis genes, including the puc operon. This mechanism, which is based on direct protein-protein interaction, is prevented by blue-light absorption of the BLUF domain located in the N-terminal part of AppA. In order to test whether AppA and PpsR are sufficient to transmit redox and light signals, we expressed these proteins in three different bacterial species and monitored oxygen- and blue-light-dependent puc expression either directly or by using a luciferase-based reporter construct. The AppA/PpsR system could mediate redox-dependent gene expression in the alphaproteobacteria Rhodobacter capsulatus and Paracoccus denitrificans but not in the gammaproteobacterium Escherichia coli. Analysis of a prrA mutant strain of R. sphaeroides strongly suggests that light-dependent gene expression requires a balanced interplay of the AppA/PpsR system with the PrrA response regulator. Therefore, the AppA/PpsR system was unable to establish light signaling in other bacteria. Based on our data, we present a model for the interdependence of AppA/PpsR signaling and the PrrA transcriptional activator.}, issn = {00219193}, keywords = {Bacterial Bacterial_Proteins DNA-Binding_Proteins Escherichia_coli Flavoproteins Gene_Expression_Regulation Light Microbial Oxidation-Reduction Oxygen Paracoccus_denitrificans Photoreceptors Photosynthesis Repressor_Proteins Rhodobacter_capsulatus Rhodobacter_sphaeroides Signal_Transduction Trans-Activators } } @inproceedings{conf/ahs/OsterlohMFB07, title = {Enhancements of reconfigurable System-on-Chip Data Processing Units for Space Application.}, author = {B.

OS is a term for software published under licence that does not give any private intellectual property rights to the developers. They invest private resources in inventions that are then fed into a common pool by contributing to a public good. A look into history shows that OS isn't a unique example of an innovation model which Allen called 'collective invention' (Allen 1983). In the second half of the nineteenth century iron-making companies in Britain's Cleveland district willingly shared their innovations in blast furnace design (Allen 1983). Other examples include the enhancement of steam engine design after 1800 (Nuvolari 2002) and the search for a dominant design in the flat panel display industry (Spencer 2003). Even though OS shares many similarities with these other cases of collective invention, there are two major differences. Firstly, collective invention regimes rarely seem to survive after the development of a dominant design (see e.g. Meyer 2002). In OS, this problem is solved with the institutional innovation of OS licences. Rather than just giving up their intellectual property rights, OS developers use these licenses to ensure that their innovations remain common property for all times (O'Mahony 2003). Secondly, the problem of enforcing the rules of cooperation established in these licenses is solved in a rather informal, decentralised way. Enforcing the rules of cooperation establishes a public good of a second order (Elster 1989). In the Open Source context, the contribution to the second order public good can only be explained by the presence of a sufficient number of norm-based intrinsically motivated contributors who are willing to carry the private costs of rule enforcement. We show that the governance mechanisms used in OS projects are especially well suited not to crowd out this special kind of motivation. We conclude that OS differentiates itself from other cases of collective invention by its success in solving the second order social dilemma of rule development and enforcement, which depends on institutional as well as motivational factors.}, doi = {10.2139/ssrn.561744}, date-modified = {2007-07-11 23:17:18 +0200}, language = {English}, local-url = {file://localhost/Users/torsten/Desktop/LW1-Arbeit/SSRN-id561744.pdf}, date-added = {2007-07-11 23:13:44 +0200}, location = {http://ssrn.com/paper=561744}, keywords = {OpenSource } } @article{Osterloh:2002, title = {Die kommerzielle Nutzung von Open-Source-Software: der Einfluss von sozialem Kapital}, author = {Margit Osterloh and Sandra Rota and Bernhard Kuster}, journal = {Zeitschrift F{\"u}hrung + Organisation}, number = {4}, pages = {211-217}, year = {2002}, biburl = {http://www.bibsonomy.org/bibtex/2471f917dbdcb72323e2c025cc9015123/torstenschuenemann}, date-modified = {2007-11-03 10:39:29 +0100}, date-added = {2007-11-03 10:39:29 +0100}, keywords = {OpenSource } } @incollection{bibtexkey, title = {Motivation and Knowledge as Strategic Resources}, address = {Berlin}, author = {Margit Osterloh and Jetta Frost}, booktitle = {Successful Management by Motivation}, editor = {Bruno S.

In dependence of the change rate of the driving field, the evolution of the ground state is studied while the transverse magnetic field is tuned through the critical point with a linear ramping. The excitation probability is obtained exactly and is compared to previous studies and to the Landau-Zener formula, a long time solution for non-adiabatic transitions in two-level systems. The exact time dependence of the excitations density in the system allows to identify the adiabatic and diabatic regions during the sweep and to study the m esoscopic fluctuations of the excitations. The effect of white noise is investigated, where the critical point transmutes into a non-hermitian ``degenerate region''. Besides an overall increase of the excitations during and at the end of the sweep, the most destructive effect of the noise is the decay of the state purity that is enhanced by the passage through the degenerate region.}, keywords = {adiabatic dynamics models noise passage phase quantum spin statphys23 topic-8 transitions } }
