The case method approach, effective in disciplines from law, forms the backbone of this classroom-proven work. Designed specifically for undergraduate courses this latest revision includes ten new cases on immigration (connection with global poverty), homelessness and foreclosures, water, ethical issues in the workplace, closing hospital emergency rooms, living together v. marriage, gay marriage, and physician-assisted death. Several cases have been dropped and the remaining cases have all been updated to keep the book contemporary with "real life" issues, for productive discussion and fruitful learning.
