The Potential Energy Surface in Molecular Quantum Mechanics
The idea of a Potential Energy Surface (PES) forms the basis of almost all
accounts of the mechanisms of chemical reactions, and much of theoretical
molecular spectroscopy. It is assumed that, in principle, the PES can be
calculated by means of clamped-nuclei electronic structure calculations based
upon the Schr\"{o}dinger Coulomb Hamiltonian. This article is devoted to a
discussion of the origin of the idea, its development in the context of the Old
Quantum Theory, and its present status in the quantum mechanics of molecules.
It is argued that its present status must be regarded as uncertain.Comment: 18 pages, Proceedings of QSCP-XVII, Turku, Finland 201
Social networking in family businesses in a local economy
Small, family owned businesses make considerable contributions to local economies. The importance of social networks to their development is also well established. This paper explores the different types of distinct, but interlocking, social networks of a rural business family, focussing upon the interaction between family, business and friendship networks. It presents a multi-rational logic framework to consider how the differing logics of each of these network influences the development and behaviour of family businesses. The changes in networks over time and between generations of the family are also analysed and gaps or structural holes within the networks identified. Implications for research and policy are then set out.div_BaM32pub4755pub
