Mucho se ha escrito recientemente sobre la necesidad de que las escuelas sean diferentes lo han sido si enfrentar los desafíos sociedad del conocimiento (por ejemplo, Hargreaves y Evans, 1997; Hargreaves, 2003; Mitchell Sackney, 2000). Los llamados persistentes a reforma escolar llevado un creciente apoyo para vistas como comunidades aprendizaje (DuFour & Eaker; 1998; Harris, 2002; Huffman ...

uring his life, Peter Mitchell put forth such radical ideas concerning cellular energetics that some scientists considered him a crackpot. Today, however, he is recognized as one of the most original and insightful biologists of all time. His chemiosmotic theories provide the basis for understanding a variety of energy interconversion mechanisms in living organisms. In 1978, Mitchell received t...

The purpose of this paper is to study the consistency correlations between the Rudin-Kiesler and the Mitchell orderings of ultrafilters. There is no direct connection between these two orderings. Thus, in general, U 6nK V does not imply UCIV or converse. Moreover, if U cRK V and UaV, then there exists a p-measurable cardinal. It is easy to construct a Rudin-Kiesler increasing sequence of length...
