The article is devoted to the analysis of economic and financial problems and contradictions accumulated in Latin America under conditions of globalization and market liberation. The originated unfavorable changes gave rise to the need of policy correction in big and small countries. The author analyses a new strategy of development adequate for Latin America with its specific geopolitical situation, demographic structure and history.

Delamination between layers occurs during the creasing and subsequent folding of paperboard. Delamination is necessary to provide some stiffness properties, but excessive or uncontrolled delamination can weaken the fold, and therefore needs to be controlled. An understanding of the mechanics of delamination is predicated upon the availability of reliable and properly calibrated simulation tools to predict experimental observations. This paper describes a finite element simulation of paper mechanics applied to the scoring and folding of multi-ply carton board. Our goal was to provide an understanding of the mechanics of these operations and the proper models of elastic and plastic behavior of the material that enable us to simulate the deformation and delamination behavior. Our material model accounted for plasticity and sheet anisotropy in the in-plane and z-direction (ZD) dimensions. We used different ZD stress-strain curves during loading and unloading. Material parameters for in-plane deformation were obtained by fitting uniaxial stress-strain data to Ramberg-Osgood plasticity models and the ZD deformation was modeled using a modified power law. Two-dimensional strain fields resulting from loading board typical of a scoring operation were calculated. The strain field was symmetric in the initial stages, but increasing deformation led to asymmetry and heterogeneity. These regions were precursors to delamination and failure. Delamination of the layers occurred in regions of significant shear strain and resulted primarily from the development of large plastic strains. The model predictions were confirmed by experimental observation of the local strain fields using visual microscopy and linear image strain analysis. The finite element model predicted sheet delamination matching the patterns and effects that were observed in experiments.

This article explores new political practices of the Roman Catholic Church by means of a close critical examination of the beatification of the Martyrs of Cajonos, two indigenous men from the Mexican village of San Francisco Cajonos, Oaxaca, in 2002. The Church’s new strategy to promote an upsurge in canonizations and beatifications forms part of a “war of images,” in Serge Gruzinski’s terms, deployed to maintain apparently peripheral populations within the Church’s central paternalistic fold of social and moral authority and influence, while at the same time as it must be seen to remain open to local cultures and realities. In Oaxaca and elsewhere, this ecclesiastical technique of “emplacement” may be understood as an attempt to engage indigenous-popular religious sensibilities and devotion to sacred images while at the same time implicitly trying to contain them, weaving their distinct local historical threads seamlessly into the fabric of a global Catholic history.
