Despite a long tradition of ethics training in business colleges, managers commonly make unethical business decisions. This paper reports a five year study of ethical decision making of business students (n = 192). In an undergraduate microeconomics course, students were presented with financial data from the infamous Ford Pinto case where defective engineering, coupled with unethical management behavior, resulted in a number of fiery fatalities. Facing the decision to repair the cars or pay the estimated costs of lost wrongful death lawsuits, 56.8% of students chose to pay for the deaths. This paper describes the classroom experiment and uses logistic regression to compare the characteristics of the group choosing the correct ethical decision (repair the cars), with the group choosing the incorrect ethical decision (pay for the deaths).

We investigated the Hirschfeld surface analysis and critical behaviour in La0.5Ca0.4Ag0.1MnO3 near the second-order ferromagnetic phase transition at Curie temperature TC. We determined the critical exponents, β, γ and δ corresponding to the temperature dependence of spontaneous magnetization, initial susceptibility and isothermal magnetization, respectively. The study of Hirshfeld surface reflects that both the electrostatic and intermolecular interactions are short range. The values for critical exponents obtained from magnetic measurements are very close to those predicted by the mean field tri-critical model.  The critical-exponent values deduced here were in a good conform to those obtained using the modified Arrott plot and Widom scaling relation.
