We provide here a general mathematical framework to model attitudes towards ambiguity which uses the formalism of quantum theory as a "purely mathematical formalism, detached from any physical interpretation". We show that the quantum-theoretic framework enables modelling of the Ellsberg paradox, but it also successfully applies to more concrete human decision-making tests involving financial, managerial and medical decisions. In particular, we elaborate a mathematical representation of various empirical studies which reveal that attitudes of managers towards uncertainty shift from ambiguity seeking to ambiguity aversion, and viceversa, thus exhibiting hope effects and fear effects. The present framework provides a promising direction towards the development of a unified theory of decisions in the presence of uncertainty. [ABSTRACT FROM AUTHOR]

Values theory posits that individuals have values and they are formed by upbringing and life's experiences and influence an individuals' cognitive processes, decisions, and behavior. Emerging onto the business scene is a new population group, the Millennials. This research seeks to explore Millennials' values from the viewpoint of their personal value orientation (PVO). Managerial PVO from the 1980s and 2010s are used as comparative populations. The Millennials' PVO is generally consistent with managerial PVO from past research. They tend toward a Personal, rather than Social, and Competence, rather than Moral, value orientation. Yet, some subtle differences emerged. Millennials are more self-focused and less other-focused than managers from the 1980s or 2010s. They emphasize competency skills more than today's managers but less than the managers of the 1980s and place more worth on moral values than managers of the 1980s but less than today's managers.

To further the debate on the ethical dimension of transformational leadership (TFL) from a virtue ethics perspective, this study focused on leaders' in-group orientation as well as their in-group versus out-group orientation in situations of conflict between organizational interests and broader ethical values. More precisely, the current study captured leaders' organizational identification (OI) as well as their willingness to engage in unethical pro-organizational behavior (UPB) and tested the relations between these attitudes and follower-perceived TFL behavior. In total, the leadership behaviors of 112 middle- and top-level managers were evaluated by 900 direct-reports. Results showed leaders' organizational identification to be positively related to TFL. However, we found no relation between leaders' willingness to engage in unethical pro-organizational behavior and TFL. Implications regarding the ethical dimension of TFL are discussed.
