The Role of the Narrative in Values-Led Business

Many leaders of values-based organizations already possess the requisite passion for the core values of their respective organizations. The ability to have their organizations perform in a manner consistent with these values is critical to gain the authenticity necessary for their audiences in order to discern the value of what that particular organization offers. The inability to articulate this to all stakeholders — including the marketplace, investors, employees, and competitors — may increase the hazard of mortality for the organization. One characteristic that human beings do not share with any other creature on earth is the ability to relate complex narratives. Narratives in leadership are synonymous with storytelling in organizations. Narratives have a much broader connotation. Narratives are an ancient art form and have the ability to create a connection between the narrator and the audience. If related well, it can create a sense of community, hone a common focus, and provide a stimulus for change. Most organizations need to address a common problem of implementing leadership tools resulting in the best outcomes for decisions. Poor leadership will inevitably increase the likelihood of organizational failure. They need to implement mechanisms that will increase positive outcomes. This paper reviews examples of leadership under impossible odds. It will reveal the necessary foundational material to provide a solid background. Next, it will address the common elements of an effective narrative as well as the importance that authenticity plays in its reception. Lastly, the elements of narrative leadership and the power it can give to those leaders who learn how to use narratives effectively will be addressed. Examples will demonstrate how effective narratives used by leaders of values-based organizations can eliminate obstacles and help their organizations perform audaciously

On the Mapping of Time-Dependent Densities onto Potentials in Quantum Mechanics

The mapping of time-dependent densities on potentials in quantum mechanics is critically examined. The issue is of significance ever since Runge and Gross (Phys. Rev. Lett. 52, 997 (1984)) established the uniqueness of the mapping, forming a theoretical basis for time-dependent density functional theory. We argue that besides existence (so called v-representability) and uniqueness there is an important question of stability and chaos. Studying a 2-level system we find innocent, almost constant densities that cannot be constructed from any potential (non-existence). We further show via a Lyapunov analysis that the mapping of densities on potentials has chaotic regions in this case. In real space the situation is more subtle. V-representability is formally assured but the mapping is often chaotic making the actual construction of the potential almost impossible. The chaotic nature of the mapping, studied for the first time here, has serious consequences regarding the possibility of using TDDFT in real-time settings

Gas- and dust evolution in protoplanetary disks

Context. Current models of the size- and radial evolution of dust in protoplanetary disks generally oversimplify either the radial evolution of the disk (by focussing at one single radius or by using steady state disk models) or they assume particle growth to proceed monodispersely or without fragmentation. Further studies of protoplanetary disks - such as observations, disk chemistry and structure calculations or planet population synthesis models - depend on the distribution of dust as a function of grain size and radial position in the disk. Aims. We attempt to improve upon current models to be able to investigate how the initial conditions, the build-up phase, and the evolution of the protoplanetary disk influence growth and transport of dust. Methods. We introduce a new version of the model of Brauer et al. (2008) in which we now include the time-dependent viscous evolution of the gas disk, and in which more advanced input physics and numerical integration methods are implemented. Results. We show that grain properties, the gas pressure gradient, and the amount of turbulence are much more influencing the evolution of dust than the initial conditions or the build-up phase of the protoplanetary disk. We quantify which conditions or environments are favorable for growth beyond the meter size barrier. High gas surface densities or zonal flows may help to overcome the problem of radial drift, however already a small amount of turbulence poses a much stronger obstacle for grain growth.Comment: accepted to A&

Human activity modeling and Barabasi's queueing systems

It has been shown by A.-L. Barabasi that the priority based scheduling rules in single stage queuing systems (QS) generates fat tail behavior for the tasks waiting time distributions (WTD). Such fat tails are due to the waiting times of very low priority tasks which stay unserved almost forever as the task priority indices (PI) are "frozen in time" (i.e. a task priority is assigned once for all to each incoming task). Relaxing the "frozen in time" assumption, this paper studies the new dynamic behavior expected when the priority of each incoming tasks is time-dependent (i.e. "aging mechanisms" are allowed). For two class of models, namely 1) a population type model with an age structure and 2) a QS with deadlines assigned to the incoming tasks which is operated under the "earliest-deadline-first" policy, we are able to analytically extract some relevant characteristics of the the tasks waiting time distribution. As the aging mechanism ultimately assign high priority to any long waiting tasks, fat tails in the WTD cannot find their origin in the scheduling rule alone thus showing a fundamental difference between the present and the A.-L. Barabasi's class of models.Comment: 16 pages, 2 figure

Guaranteed emergence of genuine entanglement in 3-qubit evolving systems

Multipartite entanglement has been shown to be of particular relevance for a better understanding and exploitation of the dynamics and flow of entanglement in multiparty systems. This calls for analysis aimed at identifying the appropriate processes that guarantee the emergence of multipartite entanglement in a wide range of scenarios. Here we carry on such analysis considering a system of two initially entangled qubits, one of which is let to interact with a third qubit according to an arbitrary unitary evolution. We establish necessary and sufficient conditions on the corresponding Kraus operators, to discern whether the evolved state pertains to either one of the classes of 3-qubit pure states that exhibit some kind of entanglement, namely biseparable, W-, and GHZ- genuine entangled classes. Our results provide a classification of the Kraus operators according to their capacity of producing 3-qubit entanglement, and pave the way for extending the analysis to larger systems and determining the particular interactions that must be implemented in order to create, enhance and distribute entanglement in a specific manner.Comment: Two new subsections included.

Contesting "Le corps militaire": Antimilitarism, Pacificism, Anarcho-Communism and 'Le Douanier' Rousseau's La Guerre

When the 1889 Military Law was passed, it established three-year universal conscriptionand a greater army of citizens to boost military preparedness for war in French coloniesand against Germany. Far from its ramifications being of no concern to neo-impressionists, it was the subject of bightingly bitter antimilitarist cartoons byMaximilien Luce and antimilitarist paintings by the neo-impressionist outsider, 'Ledouanier' Rousseau. Far from picturing the patriotic honor of becoming a soldier and thevictories of war, as did Edouard Detaille, Rousseau did the opposite. In the heat ofmilitary slaughter of families at Fourmies, Rousseau revealed how conscription wouldtransform French citizens into le corps militaire to fight not just against their arch-enemy with machine-like precision but against their very own peopl
