Axioms ruling linear negation have been investigated in the context of the complete semantics for distributive intuitionistic linear logic. Among these are the condition of being a dualizing element and the one of being a cyclic element. The motivation for analyzing other syntactic constraints comes from the observation that groupoids are models for classical linear logic. The analysis proceeds...

In this paper we propose a methodology for the estimation of Customer Satisfaction (CS) conceived as a Latent variable (LV) specified in the American Customer Satisfaction Index (ACSI) structural model. The current proposal puts forward: the approaches of structural equations based on LISREL (Joreskog, 1978), since it involves the dual problem of indeterminacy of the latent scores and the norma...

These alterations may be associated or not with cutaneous and visceral abnormalities. This work, which is a literature review, examines several studies that relate to cases of amniotic band...
