This latest volume in this important international series discusses practical errors and wrongdoing considered under the action theory (praxiological) umbrella, linking these to ethical behavior. Human actions related to the conduct of business should be effective and efficient. But such praxiological criteria are of secondary importance to norms that should also be taken into account. The primary norm is ethical behavior, which defines the morality of business activities on the basis of the good; these are the presupposed foundations for the human actions in business.The articles in this volume discuss whistleblowing, or the exposure of behavior that violates the ethical foundations of business. They are written from different angles and present a variety of experiences, adding new value to both the subject of praxiology as well as ethics as it relates to economic activity in its social and global context. The issues, problems, and questions raised by this international group of eminent scholars have much to add to the contemporary debate induced by the present economic crises. These crises have revealed practical errors and hypocrisy of those responsible for leadership and management, primarily of financial institutions.
