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...

We demonstrate a negative relationship between pro-market reforms and the sustainability of superior profits in an emerging economy. The decline in sustainability of superior profits shows that pro-market reforms bring significant threats in addition to the various opportunities such as greater availability of production factors and greater freedom to enter and operate businesses highlighted in...

This paper investigates the effect of capacity constraints on the sustainability of collusion in markets subject to cyclical demand fluctuations. In the absence of capacity constraints (i.e. a limiting case of our model), Haltiwanger and Harrington (1991) show that firms find it more difficult to collude during periods of decreasing demand. We find that this prediction can be overturned if firm...

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 ...

We present the findings from a Dutch field study of 30 outsourcing deals totaling to more than 100 million Euro, where both customers and corresponding IT-outsourcing providers participated. The main objective of the study was to examine from a number of well-known factors whether they discriminate between IT-outsourcing success and failure in the early phase of service delivery and to determin...

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...
