  The EWG OR and Ethics, Public Service Management Analytics and Societal Complexity focus at ethical subjects in doing research in the way of how to make the world a better place to live for all people. Giving that each researcher has only one life, the members of both these research groups decided to dedicate their lives, research capability, brains and efforts to improve the living conditions of all the people in the world. This idea of research often includes criticizing issues and circumstances that abuse privacy, like unethical use of data mining for companies, Google and Facebook, abuse health of people by the alcohol and tobacco industry, criticize unethical labor conditions like child labor, improving the position of women by emphasizing education of women, especially in developing countries, by being financial independent, by forbidding child marriages and stimulate equal pay for equal jobs given that women rights are human rights. Reflecting and handling these kind of complex societal ethical problems is the focus of the researchers belonging to the EWG OR and Ethics and Societal Complexity. In most complex societal problems some persons benefit while most people suffer. Given this reality the researchers of our EWG research group of OR and Ethics and Societal Complexity like to minimalize the personal benefit of those who profit of the complex problems, like the banks who created the credit crisis and the pharmacy industry who benefited of dangerous drugs and to maximize the situation of all people in a social based democracy where all people can be protected by the rule of law in a social based democracy. This session also proposes and promotes Public Service Management Analytics, together and in its parts. These are: Analytics: a technical approach to analysing problems and their solutions. Management: of people by people, in the pursuit of putting solutions into practice. Service: addressing the challenges of climate change, global criminal gangs, abuses of people and peoples, energy deficits, depletion and destruction of natural resources. And solutions involving the Public, working with the Public, for the benefit of the Public. We invite all researchers who are, like us, doing research for improving the level of living in a sustainable way to join our conference of EURO and OR in Leeds.
