Autocatalytic dissociation of water on the Cu(110) metal surface is demonstrated on the basis of X-ray photoelectron spectroscopy studies carried out in situ under near ambient conditions of water vapor pressure (1 Torr) and temperature (275-520 K). The autocatalytic reaction is explained as the result of the strong hydrogen-bond in the H2O-OH complex of the dissociated final state, which lower...

Adsorption and catalytic properties of the polar (111) surface of transition-metal carbides (TMC's) are investigated by density-functional theory. Atomic and molecular adsorption are rationalized with the concerted-coupling model, in which two types of TMC surface resonances (SR's) play key roles. The transition-metal derived SR is found to be a single measurable descriptor for the adsorption p...

In recent years the interest in expertise and proficiency has been raising, in educational research, knowledge management as well as in cognitive science. The expert’s know how or procedural knowledge is often hidden even for him or her self, it is tacit. ”We can know more than we can tell”.(Polanyi, 1967) This paper is an “Integrative research review”, trying to show new aspects of experience-...

Si bien en el papel los modelos de enseñanza instrumental han ido migrando paulatinamente hacia una perspectiva corte constructivista y ecológica, la pedagogía tradicional enfoque prescriptivo permanece vigente las aulas música. En esta, conceptos, teorías procedimientos tienden a tratarse como normas universales o verdades absolutas. Teniendo referente ideas Michael Polanyi sobre conocimiento ...

I this article we argue that discourse structure constrains the set of possible constituents in a discourse that can provide the relevant context for structuring information in a target sentence, while information structure critically constrains discourse structure ambiguity. For the speaker, the discourse structure provides a set of possible contexts for continuation while information structur...

It is sometimes claimed (cf. that discourse has a tree structure which reeects the semantic structure of discourse. In this paper, I argue that this claim is problematic in cases of discourse multiple dependencies i.e. cases where one discourse segment is semantically related to two discourse segments. I develop a discourse framework which is based on Scha/Polanyi 1988] but integrates ideas fro...

This paper makes a theoretical critique of the concept of scientific knowledge. The classical conception of scientific knowledge has been discussed and analyzed in the first section. In the second section, emerging conception of the scientific knowledge has been explored. The author hopes to show on the basis of veritable critique from different philosophers of science as well as scientist (Kuh...
