Membrane vesicles of Clostridium thermoautotrophicum containing carbon monoxide dehydrogenase generated a proton motive force when exposed to CO. This proton motive force, with a value of -140 mV, consisted of only an electrical potential at pH 7.5 and above and of an electrical potential and pH gradient at a lower pH. The proton motive force drove the uptake of L-alanine by the vesicles to a c...

Zusammenfassung Es existieren zahlreiche Motive und Barrieren zur Nutzung von Social Software in Unternehmen und Organisationen. Ein mögliches Anwendungsszenario ist das interorganisationale Krisenmanagement von Behörden und Organisationen mit Sicherheitsaufgaben, Unternehmen und Bürgern bei Großschadenslagen. In diesem Beitrag werden Motive und Barrieren der Nutzung von Social Software in Unte...

I present a tactic, BasicElim, for Type Theory based proof systems to apply elimination rules in a reenement setting. Applicable rules are parametric in their conclusion, expressing the leverage hypotheses ~ x yield on any ~ x we choose. represents the motive for an elimination: BasicElim's job is to construct a suited to the goal at hand. If these ~ x inhabit an instance of 's domain, I adopt ...

I analyze the rm's decision of how much general but informal training to provide in the presence of on-the-job search. In particular, due to lack of formal measure and commitment technology on the training intensity, I assume that rms exibly adjust their training intensity at any time, but hardly charge the cost of training to their workers. Even without any contractual agreement on training, r...

The compensatory model of motivation and volition is based on the assumption that discrepancies between implicit and explicit motives lead to psychological conflict, and that resolution of this conflict requires volitional regulation and consumes volitional strength. This suggests that implicit/explicit motive discrepancies (IED) are responsible for decreases in volitional strength. A longitudi...

This paper aims at contributing to the ongoing efforts to get a firmer grasp of the systematic significance of the entanglement of idealism and empiricism in Helmholtz's work. Contrary to existing analyses, however, the focal point of the present exposition is Helmholtz's attempt to articulate a psychological account of objectification. Helmholtz's motive, as well as his solution to the problem...
