    "abstract": "A new mean field statistical mechanics model of two interacting groups of\nspins is introduced and the phase transition studied in terms of their relative\nsize. A jump of the average magnetization is found for large values of the\nmutual interaction when the relative percentage of the two populations crosses\na critical threshold. It is shown how the critical percentage depends on\ninternal interactions and on the initial magnetizations. The model is\ninterpreted as a prototype of resident-immigrant cultural interaction and\nconclusions from the social sciences perspectives are drawn.",
