Global factors which influence the directions of social development [PDF]
, 2017 This study identifies global factors conditioning the global problematics of the direction of social development. Global threats were evaluated and defined as dangerous processes, phenomena, and situations that cause harm to health ...

Multiple Ways of Processing in Questionnaires
Ratio Mathematica, 2017 In social sciences when questionnaires are used, there is a new tool, the bar instead of Likert scale. The bar has been suggested by Vougiouklis & Vougiouklis in 2008, who have proposed the replacement of Likert scales, usually used in questionnaires ...

Introduction to Dependence Relations and Their Links to Algebraic Hyperstructures
Mathematics, 2019 The aim of this paper is to study, from an algebraic point of view, the properties of interdependencies between sets of elements (i.e., pieces of secrets, atmospheric variables, etc.) that appear in various natural models, by using the algebraic ...

Chemical Examples in Hypergroups
Ratio Mathematica, 2003 Hypergroups first were introduced by Marty in 1934. Up to now many researchers have been working on this field of modern algebra and developed it. It is purpose of this paper to provide examples of hypergroups associated with chemistry.

Completely simple and regular semi hypergroups [PDF]
, 2012 In this paper the notion of simple and completely simple semi hypergroups are introduced. Basic properties of these algebraic structures are considered. Some methods for constructing new kinds of these hyperstructures are presented.

A Hyperstructure is founded on the concept of a powerset, providing a framework for modeling relationships among elements of a set [1, 2]. Building on this, a Superhyperstructure employs the 𝑛-th powerset to capture multi-layered hierarchical systems, enabling deeper abstractions and higher levels of complexity [3, 4].
