In this paper, we regard dilaton in Weyl-scaled induced gravitational theory as coupled Quintessence, which is called DCQ model by us. Parametrization of the dark energy model is a good method by which we can construct the scalar potential directly from the effective equation of state function ωσ(z) describing the properties of the dark energy. Applying this method to the DCQ model, we consider...

The Barbero–Immirzi (BI) parameter is promoted to a field and a canonical analysis is performed when it is coupled with a Nieh–Yan topological invariant. It is shown that, in the effective theory, the BI field is a canonical pseudoscalar minimally coupled with gravity. This framework is argued to be more natural than the one of the usual Holst action. Potential consequences in relation with inf...

This paper analyses data collected in 2012 and 2013 at the ESSEC Business School from Kallystée, a proprietary mass-attendance business game. Company boards are simulated by teams of five students selected at random. The design manipulates the gender composition of the boards to allow for all possible gender combinations. Data show that all-men and mixed teams with four women perform significan...

We present results on the spin-independent quark-antiquark potential in SU(3) gauge theory from a simulation on a 483×64 lattice at β = 6.8, corresponding to a volume of (1.7 fm). Moreover, a comprehensive analysis of spinand velocitydependent potentials is carried out for SU(2) gauge theory, with emphasis on the short range structure, on lattices with resolutions ranging from .02 fm to .04 fm....

We study how norms can solve distributional conflict inside a clan and the efficient coordination of collective action in a conflict with an external enemy. We characterize a fully non-cooperative equilibrium in a finite game in which a self-enforcing norm coordinates the members on efficient collective action and on a peaceful distribution of the returns of collective action. JEL Classificatio...

This chapter discusses practices, opportunities, and challenges in local e-government project management by means of a case study involving interviews, document studies, and an element of action research, over eight months. The analysis against e-government success factors finds seven “critical issues”; political timing, resource allocation, political mandate, distinction between administrative...

Multi Agent Relational Action Learning considers a community of agents, each rationally acting following some relational action model. The observed effect of past actions that led an agent to revise its action model can be communicated, upon request, to another agent, speeding up its own revision. We present a framework for such collaborative relational action model revision.

The two informal ‘mental landscapes’ that provide the intuitive substratum for stateoriented and event-oriented formal specifications are discussed, and abstractly characterised as networks of constraints. The structuring facilities offered by the two approaches are contrasted. A technique is introduced for expanding an event-oriented specification consisting of a fixed pattern of interacting p...
