In this paper are introduced some concepts of interval-valued fuzzy relations and some of their properties: reflexivity, symmetry, T-transitivity, composition and local reflexivity. The existence and uniqueness of T-transitive closure of interval-valued fuzzy relations is proved. An algorithm to compute the T-transitive closure of finite interval-valued fuzzy relations is showed. Some propertie...

We study atomic decompositions and their relationship with duality and reflexivity of Banach spaces. To this end, we extend the concepts of “shrinking” and “boundedly complete” Schauder basis to the atomic decomposition framework. This allows us to answer a basic duality question: when an atomic decomposition for a Banach space generates, by duality, an atomic decomposition for its dual space. ...

In this paper, we first give the cartesian product of two neutrosophic multi sets(NMS). Then, we define relations on neutrosophic multi sets to extend the intuitionistic fuzzy multi relations to neutrosophic multi relations. The relations allows to compose two neutrosophic sets. Also, various properties like reflexivity, symmetry and transitivity are studied. AMS 03E72, 08A72 Keyword 0.1 Neutro...

Critical realism is a subject of growing interest in the IS literature. This article aims at implementing a critical realist framework: Margaret Archer's (2003) internal conversation theory. As a contemporary sociologist, Archer suggests both a general vision of social practice and a typology of reflexivity modes. Her multilayered framework could be extremely useful in overcoming a current limi...

George Soros’s reflexivity theory is quite compatible with second order cybernetics. Indeed his work shows how to apply ideas in second order cybernetics to economics, finance, and political science. This paper briefly reviews three theories of reflexivity in cybernetics. It provides an introduction to Soros’s version of reflexivity theory and reviews applications in economics and finance. Soro...

In this article, we considered bidual spaces and reflexivity of real normed spaces. At first we proved some corollaries applying Hahn-Banach theorem and showed related theorems. In the second section, we proved the norm of dual spaces and defined the natural mapping, from real normed spaces to bidual spaces. We also proved some properties of this mapping. Next, we defined real normed space of R...

Faced with strong environmental issues, the agricultural sector has to revise deeply its aims and performance criteria. Numerous methods have been proposed to involve heterogeneous stakeholders in farming system design, and several authors highlight the importance of reflexivity in such projects. Our paper aims at strengthening this reflexivity by proposing a comparative analysis framework cont...

This paper explains the continuing relevance of Keynes’s philosophical thinking in terms of his anticipation of complexity thinking in economics. It argues that that reflexivity is a central feature of the philosophical foundations of complexity theory, and shows that Keynes employed an understanding of reflexivity in both his philosophical and economic thinking. This argument is first develope...

This paper presents the findings of an in-depth investigation of situated activities of developers and managers during an embedded system development. Previous empirical investigations claim that software design may involve activities outside the continuum of methodologies, such as improvisation or situated activities. Those activities may involve reflexive practices that are purposefully appli...
