"Welcome to the 7th edition of Quantitative Analysis for Decision Makers (previously titled Quantitative Methods for Decision Makers). It's 30 years since this book was first published and much has changed in the world of business and management since then. The internet was only just becoming...

The single-impurity specific heat ci(T) and impurity susceptibility χi(T) of an extended s–d Hamiltonian H are derived and examined in the vicinity of the transition temperature Tc. ci(T) is found by exploiting the single-impurity solution of H due to Andrei et al., whereas χi(T) by applying...

The UK government's Best Value initiative is intended to ensure that councils provide best value in service delivery and emphasizes the importance of ensuring a clear customer/citizen focus across all services. The Accounts Commission and Audit Scotland have statutory responsibilities for...

The new Labour Government elected in the UK in 1997 has a declared commitment to the modernisation of local government and has proposed radical change to the way councils plan and deliver local services through best value in service delivery. Best value emphasises the role of sound management as...

An anisotropic generalization of the reduced s–d model with antiferromagnetically coupled impurities is proposed. This extension consists in introducing different coupling constants of s–d interaction and interimpurity coupling for spin components along the c-axis and perpendicular to the...
