Search engines - such as Google - have been characterized as "Databases of intentions". This class will focus on different aspects of intentionality on the web, including goal mining, goal modeling and goal-oriented search. Readings: M. Strohmaier, M. Lux, M. Granitzer, P. Scheir, S. Liaskos, E. Yu, How Do Users Express Goals on the Web? - An Exploration of Intentional Structures in Web Search, We Know'07 International Workshop on Collaborative Knowledge Management for Web Information Systems in conjunction with WISE'07, Nancy, France, 2007.

The molecules of ethyl 4-(5-amino-3-methyl-1H-pyrazol-1yl) benzoate, C13H15N3O2, are linked by two independent N-H center dot center dot center dot O hydrogen bonds into a chain of edge-fused and alternating R-4(2)(8) and R-2(2)(20) rings. A combination of N-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds links the molecules of methyl 4-(5-amino-3-tert-butyl-1H-pyrazol-1-yl) benzoate, C15H19N3O2, into sheets of alternating R-2(2)(20) and R-6(6)(32) rings. In 4-(5-amino-3-methyl-1H-pyrazol-1-yl) benzoic acid monohydrate, C11H11N3O2 center dot H2O, the molecular components are linked into a three-dimensional framework structure by a combination of five independent hydrogen bonds, two of O-H center dot center dot center dot N type and one each of O-H center dot center dot center dot O, N-H center dot center dot center dot O and N-H center dot center dot center dot N types

Resumen: Este texto explora el sentido y la posibilidad de introducir la teoría de Ilya Prigogine “estructuras disipativas” en el contexto de las organizaciones. La tesis aquí propuesta afirma que las organizaciones son sistemas abiertos, alejados del equilibrio y tiene que ver con posibilidades creativas, antes que con realidades fácticas. Por lo tanto, las organizaciones de no-equilibrio están constituidas por fenómenos de comportamientos espontáneos o coherentes que reclaman para sobrevivir cierta disipación de energía y, por tanto, el mantenimiento de una interacción con el mundo exterior. Con ello la gerencia adquiere un papel destacado en el estudio de las organizaciones como estructuras disipativas encaminadas a generar y permitir el Biodesarrollo. Palabras claves: Estructuras Disipativas, Fluctuaciones, Bifurcaciones, Gerencia, Biodesarrollo, Auto-eco-organizador. Abstract: This text explores the sense and possibility of introducing Ilya Prigogine´s theory “dissipative structures”, into organizations´ context. The thesis proposed here states that organizations are open systems which are far away from equilibrium and had to deal with creative possibilities before being practical realities. Thus, no-equilibrium organizations are made of spontaneous or coherent behavioral phenomenon that strives to survive a certain amount of energy loss, hence the maintenance of interaction with external world. This way organizations management acquires an outstanding roll in studying organizations as dissipative structures prone to create and allow bio-development.Key Words: Dissipative Structures, Fluctuation, Bifurcation, Management, Bio-development, eco-self-organizer.
