A cluster series is established for the cooperative Jahn-Teller-T-e and theT-t-systems in the simple cubic and square lattices. We calculate the phase transition temperature Tc, the specific heat and the “susceptibility” in zero order and in 2-site cluster approximation. Additionally in the...

Based on arguments about long-term orientation and corporate reputation, we argue that family and founder firms differ from other firms with regard to corporate social responsibility. Using Bayesian analysis, we then show that family and founder ownership are associated with a lower level of...
