We show that isomorphism of effect algebras preserves properties of effect algebras derived from effect algebraic sum ? of elements. These are partial order, order convergence, order topology, existence of states and other important properties. However, t... see more

We show that (generalized) effect algebras may be suitable very simple and natural algebraic structures for sets of (unbounded) positive self-adjoint linear operators densely defined on an infinite-dimensional complex Hilbert space. In these cases the eff... see more

We continue in the direction of our paper on PT-Symmetry in (Generalized) Effect Algebras and Partial Groups. Namely we extend our considerations to the setting of weakly ordered partial groups. In this setting, any operator weakly ordered partial group i... see more

We study the set of all positive linear operators densely defined in an infinite-dimensional complex Hilbert space. We equip this set with various effect algebraic operations making it a generalized effect algebra. Further, sub-generalized effect algebras... see more

Off-farm employment is an important strategy for complementing farm household income and maintaining rural livelihoods. A multilevel logistic regression model was applied to investigate the effect of farm-level and regional-level factors on off-farm emplo... see more

Four experiments were conducted to investigate the role of metaphor-based schemas in text comprehension and representation in English and Tunisian Arabic among 80 Tunisian MA students of English. The study explores specifically, the extent to which topic ... see more

Teaching the concept of fractions to students stays challenging, yet representations define an effective strategy to overcome such a challenge. Considering the impact of teachers’ knowledge on students’ achievement, this study aimed at portraying mathemat... see more

The information maintenance technology of machine operator training quality assessment with numerical programmed control (the machine operator), which ensures the operation of the “Operator – Machine Tool – Part Manufacturing Program” (OMMP) sys... see more

Juvenile justice develops its intervention taking into account the particularities of the psycho-evolutionary and social moment of young people. Intervention with juvenile offenders has the dual objective of rehabilitating the young and preventing recidiv... see more
