Moral exemplars provide us with important case studies of optimal moral flourishing. Although most historians rate Abraham Lincoln as the most moral American president, their analyses do not utilize the perspective of moral development theory or research. This project asked whether such a perspective could contribute to a better understanding of Lincoln’s abundantly well-examined self and actions. This study examined the moral self of U.S. President Abraham Lincoln through close textual analysis of his brief autobiographical writings and his ethical turning point, his 1854 Peoria Speech attacking the morality of slavery. Even the limited sample of one major speech and three brief writings about life events provided evidence for the usefulness of McAdams’ method of examining life narratives for central themes and textual elements and for Colby and Damon’s (1992) method of interviewing exemplars and identifying common traits. Our methods allowed for no carefully constructed interview or clarification questions but rather relied on historical texts constructed for political goals. Major figures in the exploration of moral selves suggest that the centrality of morality to people’s sense of self lies at the heart of moral motivation and action. Studies of historical moral exemplars provide individuals and organizations with powerful role models for optimal ethical functioning and highlight the importance of fostering the centrality of morality in organizational leaders.

In this study I revisit the Cuban missile crisis of 1962, in order to gain additional perspective on the relationship between organizational decision making and crisis outcomes. This exercise is an historical “counterfactual” or “what if” excursion, using recently declassified documents and simulated exchange calculations, from which I hope to draw three principal benefits. First, the study may shed some additional light on why Soviet Premier Nikita Khrushchev was willing to take such a dangerous gamble. Second, our counterfactual crisis suggests that the risk of inadvertent war, so much written about in connection with Cuba, 1962, was less important than the risk of a deliberate, but miscalculated, escalation. Third, the balance of command and control vulnerability might have mattered more to crisis‐ridden US leaders than the balance of strategic nuclear forces. If so, it helps to explain the apparent reluctance of US leaders to employ highly coercive forms of nuclear brinkmanship.

The purpose of this paper is to study the effects of Angle of Attack (AOA), Axis Ratio (AR) and Reynolds number (Re) on unsteady laminar flow over a stationary elliptic cylinder.

The governing equations of fluid flow over the elliptic cylinder are solved numerically on a Cartesian grid using Projection method based Immersed Boundary technique. This numerical method is validated with the results available in open literature. This scheme eliminates the requirement of generating a new computational mesh upon varying any geometrical parameter such as AR or AOA, and thus reduces the computational time and cost.

Different vortex shedding patterns behind the elliptic cylinder are identified and classified using time averaged centerline streamwise velocity profile, instantaneous vorticity contours and instantaneous streamline patterns. A parameter space graph is constructed in order to reveal the dependence of AR, AOA and Re on vortex shedding. Integral parameters of flow such as mean drag, mean lift coefficients and Strouhal number are calculated and the effect of AR, AOA and Re on them is studied using various pressure and streamline contours. Functional relationships of each of integral parameters with respect to AR, AOA and Re are proposed with minimum percentage error.

The results obtained can be used to explain the characteristics of flow patterns behind slender to bluff elliptical cylinders which found applications in insect flight modeling, heat exchangers and energy conservation systems. The proposed functional relationships may be very useful for the practicing engineers in those fields.

The results presented in this paper are important for the researchers in the area of bluff body flow. The dependence of AOA on vortex shedding and flow parameters was never reported in the literature. These results are original, new and important.

This paper aims to address the limitations of classical deterrence theory in dealing with violent non-state actors (VNSAs).

The study uses qualitative methods.

It suggests that two measures must be applied; the first one is to rephrase the assumptions of the theory towards a broader definition. The second one is to theorize certain approaches for deterring VNSAs which shall remain a key component in, but not the cornerstone of, national security strategies.

In the aftermath of 9/11 attacks and US war on terrorism, the need arose to “revisit” the “Deterrence Theory” to address several changes such as rogue states, cyber threats and VNSAs, especially after the end of the Cold War, when the theory was originally developed. The recent research on VNSAs relates to the fourth wave of deterrence, which highlights its proper role in a new security environment.
