During the 1960’s, many as was firmly supported by the historical founders of econometrics, had hoped that econometrics would provide a sound scientific foundation for econometrics in which each element of specification would be determined primarily on the basis of economic theory. However, due to misusing of econometrics and also wide usage of the so called cookbook econometrics, many research...

In 1990, we published the following result: Let m be a regular cardinal > א0. Every m-algebraic lattice L can be represented as the lattice of m-complete congruence relations of an m-complete modular lattice K. In this note, we present a short proof of this theorem. In fact, we present a significant improvement: The lattice K we construct is 2-distributive.

published in Advance ACS Absrracrs, March 15, 1994. 0022-3654/94/2098-4180%04.S0/0 associated with the use of the resulting potential, since it is well known that the evaluation of many-body functions is computationally demanding.

We study the evolution of Slovenia’s scientific collaboration network from 1960 till present with a yearly resolution. For each year the network was constructed from publication records of Slovene scientists, whereby two were connected if, up to the given year inclusive, they have coauthored at least one paper together. Starting with no more than 30 scientists with an average of 1.5 collaborato...
