We study Morita invariants for strongly Morita equivalent partially ordered semigroups with several types of local units. These include the greatest commutative images, satisfying a given inequality and the fact that strong Morita equivalence preserves various sublattices of the lattice of ideals.

urban management in any context has a different economic, social and political structure, which is in harmony with the existing models of organization. in spite of these differences, in order to reach a sustainable urban development, several different conferences should be referred to. in the “brundtland commission 1987” about urban sustainable development these definitions have been given: “pr...

This quantity was introduced in 1969 by Cheeger [1] to bound from below the spectral gap of the Laplacian on compact Riemannian manifolds, and nowadays (1) is often called an isoperimetric inequality of the Cheeger type. The relationship between more general isoperimetric and certain Sobolev type inequalities was earlier considered by Maz’ya [2] (see for history, for example, [3, 4]). What was ...

Visual perspective taking (VPT) – people’s ability to represent the physical world from another person’s viewpoint – plays a fundamental role in social cognition. However, little is known about whether and when VPT can be triggered spontaneously without any explicit verbal prompting. In six studies, we measured spontaneous VPT as the tendency to read an ambiguous number from another agent’s ima...

This paper proposes a new approach for analyzing the relationship between macroeconomic factors and the income distribution. The conventional method of analysis is regression of summary inequality indices on variables such as the unemployment and inflation rates. Building on the lessons from recent advances in time-series econometrics, we suggest instead that one should first fit a parametric f...

This Essay addresses the negative impact of human cloning on the family, and argues further that market incentives to develop and implement cloning techniques exploit and exacerbate socioeconomic inequities. It suggests that cloning should be prohibited internationally and examines possible routes to that aim. To begin with, it offers some reflections on the nature of moral argument, and on the...
