Price indeterminacy and bargaining in a market with indivisibilities
(Elsevier, 1993)
We consider an exchange market for an indivisible, heterogeneous good where pairs of buyers and sellers bargain over prices in different transactions. A stable outcome in one negotiation cannot be uniquely determined by ...
The nature of middle school learners' science content understandings with the use of on-line resources
(Wiley Subscription Services, Inc., A Wiley Company, 2003-03)
Early research on using the World Wide Web indicated that middle school students did not explore much and used Web tools naively. In response to these challenges, an on-line research engine, Artemis, was designed to provide ...
Critical analysis of the graphical determination of hansen's solubility parameters for lightly crosslinked polymers
(Wiley Subscription Services, Inc., A Wiley Company, 1996-12-19)
The most widely accepted method for determining Hansen's three-dimensional solubility parameters (3DSP) for crosslinked polymers entails graphically estimating the center of a spherical region in 3DSP-coordinate space whose ...
Quantifying the uncertainty about the half-life of deviations from PPP
(John Wiley & Sons, Ltd., 2002-03)
We propose a Bayesian framework in which the uncertainty about the half-life of deviations from purchasing power parity can be quantified. Based on the responses to a survey study, we propose a prior probability distribution ...
Annealing effects of polymers and their underlying molecular mechanisms
(Elsevier, 1976-04)
This paper indicates that changes in chain mobility, heat capacity, WAXS crystallinity, SAXS long period, SAXS peak intensity, specific volume and morphology as a function of increasing temperature, occur in three fairly ...
Characterization of optima in smooth Pareto economic systems
(Elsevier, 1975)
Simple techniques of calculus and geometry are used to study and characterize the optima of pure exchange economies in which the utility functions are smooth but not necessarily convex. It is also shown how one can reduce ...
Methane to methanol in supercritical water
(Elsevier, 1994-06)
We examined the feasibility of producing methanol from the partial oxidation of methane in near-critical and supercritical water. Oxygen was always the limiting reactant. The parameter space investigated experimentally ...
