It offers a model which is called „articulation of cultural modes". The paper agrees with Ronald Inglehart that 'culture' is now playing a more dominant role in the social formation of current societies, as 'technology' once did in the modern era. But it goes one step further by arguing that culture cannot be approached as a holistic concept building on a comprehensive theoretical framework.}, language = {en} } @article{Abel2004, author = {Abel, Markus}, title = {Nonparametric modeling and spatiotemporal dynamical systems}, issn = {0218-1274}, year = {2004}, abstract = {This article describes how to use statistical data analysis to obtain models directly from data.

Morphological characterization was carried out by transmission electron microscopy. These triblock terpolymers self-assemble into various core-shell type or lamellar morphologies. In the SBV/SV blends, macrophase separation between the two block copolymers, continuous centrosymmetric lamellae and stacks of non-centrosymmetric lamellae with anti-parallel orientation were found. In the blends of SBV/VC, macrophase separation was never observed, what is due to the specific interactions between S and C domains.

However, Glg2p possesses an additional tyrosine residue, Tyr230 and therefore two potential autoglucosylation sites. Glucosylation of Glg2p was studied using both matrix-assisted laser desorption ionization and electrospray quadrupole time of flight mass spectrometry. Glg2p, carrying a C-terminal (His(6)) tag, was produced in Escherichia coli and purified. By tryptic digestion and reversed phase chromatography a peptide (residues 219-246 of the complete Glg2p sequence) was isolated that contained 4-25 glucosyl residues. Following incubation of Glg2p with UDPglucose, more than 36 glucosyl residues were covalently bound to this peptide. Using a combination of cyanogen bromide cleavage of the protein backbone, enzymatic hydrolysis of glycosidic bonds and reversed phase chromatography, mono- and diglucosylated peptides having the sequence PNYGYQSSPAM were generated. MS/MS spectra revealed that glucosyl residues were attached to both Tyr232 and Tyr230 within the same peptide. The formation of the highly glucosylated eukaryotic Glg2p did not favour the bacterial glycogen accumulation. Under various experimental conditions Glg2p-producing cells accumulated approximately 30\% less glycogen than a control transformed with a Glg2p lacking plasmid. The size distribution of the glycogen and extractable activities of several glycogen-related enzymes were essentially unchanged. As revealed by high performance anion exchange chromatography, the intracellular maltooligosaccharide pattern of the bacterial cells expressing the functional eukaryotic transgene was significantly altered. Thus, the eukaryotic glycogenin appears to be incompatible with the bacterial initiation of glycogen biosynthesis}, language = {en} } @article{AleAghaBolayBraunetal.2004, author = {Ale-Agha, Nosratollah and Bolay, Adrien and Braun, Uwe and Jage, Horst and Kummer, Volker and Lebeda, Ales and Piatek, Marcin and Shin, Hyeon-Dong and Zimmermannova-Pastircakova, Katarina}, title = {Erysiphe catalpae and E. elevata in Europe}, year = {2004}, language = {en} } @phdthesis{Allefeld2004, author = {Allefeld, Carsten}, title = {Phase synchronization analysis of event-related brain potentials in language processing}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-0001873}, school = {Universit{\"a}t Potsdam}, year = {2004}, abstract = {Das Forschungsthema Synchronisation bildet einen Schnittpunkt von Nichtlinearer Dynamik und Neurowissenschaft.

Under the assumption that the X-ray gas mass fraction measured within r(2500) is constant with redshift and using only weak priors on the Hubble constant and mean baryon density of the Universe, we obtain a clear detection of the effects of dark energy on the distances to the clusters, confirming (at comparable significance) previous results from Type la supernovae studies. For a standard Lambda cold dark matter (CDM) cosmology with the curvature Omega(K) included as a free parameter, we find Omega(Lambda) = 0.94(-0.23)(+0.21) (68 per cent confidence limits). We also examine extended XCDM dark energy models. Combining the Chandra data with independent constraints from cosmic microwave background experiments, we find Omega(X) = 0.75 +/- 0.04, Omega(m) = 0.26(- 0.04)(+0.06) and w(X) =-1.26 +/- 0.24. Imposing the prior constraint w(X) > -1, the same data require w(X) < -0.7 at 95 per cent confidence. Similar results on the mean matter density and dark energy equation of state parameter, \&UOmega;(m) = 0.24 ± 0.04 and w(X) 1.20(-0.28)(+0.24), are obtained by replacing the cosmic microwave background data with standard priors on the Hubble constant and mean baryon density and assuming a flat geometry}, language = {en} } @article{Allkaemper2004, author = {Allk{\"a}mper, Urte Christine}, title = {Die Braut des Soldaten}, series = {Milit{\"a}r und Gesellschaft in der fr{\"u}hen Neuzeit}, volume = {8}, journal = {Milit{\"a}r und Gesellschaft in der fr{\"u}hen Neuzeit}, number = {1}, issn = {1861-910X}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-20261}, pages = {45 -- 48}, year = {2004}, language = {de} } @book{AlpersDietzschEppetal.2004, author = {Alpers, Karsten and Dietzsch, Volker and Epp, Thomas and Jahnke, Thomas and Janßen, Martin and Siekmann, Angelika and Simanowsky, Ursula and Wuttke, Hans}, title = {Mathematik : Analytische Geometrie lineare Algebra ; Orientierungswissen Stochastik ; Handreichungen f{\"u}r den Unterricht ; Gymnasiale Oberstufe ; NRW}, series = {Orientierungswissen Stoachstik}, journal = {Orientierungswissen Stoachstik}, publisher = {Cornelsen}, address = {Berlin}, isbn = {3-464-57282-x}, pages = {456 S.}, year = {2004}, language = {de} } @article{AndersBeierBrunketal.2004, author = {Anders, Kenneth and Beier, Wolfgang and Brunk, Ingo and Burkart, Bettina and Mrzljak, Anders and Oehlschl{\"a}ger, Susanne}, title = {Freie Sukzession und Offenlandmanagement}, isbn = {3-540-22449-1}, year = {2004}, language = {de} }
