However, the proxies for performance and diversification that have been employed in past strategy research has not been unanimously agreed upon. Given the current state of confusion that exists with regard to the topic of diversification, performance and its relationship within an inter...
متن کاملAtoms and bonds in molecules and chemical explanations
The concepts of atoms and bonds in molecules which appeared in chemistry during the nineteenth century are unavoidable to explain the structure and the reactivity of the matter at a chemical level of understanding. Although they can be criticized from a strict reductionist point of view, because neither atoms nor bonds are observable in the sense of quantum mechanics, the topological and statis...
متن کاملNon-Extensive Entropies on Atoms, Molecules and Chemical Processes
During the last decade, information theory [1] as applied to the basic sciences has taken two routes in the study of physical and chemical systems, considering both extensivity and non-extensivity these concepts are fundamental to the development of new physical theories that try to describe the behaviour of natural systems. In this sense, non-extensivity is an important concept that it is nece...
متن کاملAtoms and Molecules
An atom is a system formed by a pack of electrically charged particles Q called nucleus and N identical particles of charge q − . Molecules are systems with several nuclei which may not necessarily be identical . In almost all matter, the nuclei are conglomerates of neutrons and protons and the N remaining particles are electrons. Other atomic systems will be described in the exotic atoms section.
