ASSESSMENT OF THE BRICS MONETARY POLICY by A. A. Aliev

“…A set of theoretical, practical and methodological issues of determining the economic status of the state, based on the use of indicators of stability, dynamic and qualitative indicators of state development has been examined for obtaining a generalized assessment of monetary policy on the example of the BRICS countries. The fuzzy set tools, peer review, graphic analysis, and tools for calculating common integral indicators, based on selected indicators, reflecting its state, have been used. …”

Public sector corruption in South Asia: focusing on institutional factors with a two-step fsQCA by Jinwon Han, Chanwahn Kim

“…Abstract While the influence of institutions on public sector corruption is widely recognised, empirical exploration of their specific effects remains limited. Using a two-step fuzzy-set qualitative comparative analysis (fsQCA), this paper identifies several causal combinations of political and economic institutions that contribute to higher levels of public sector corruption in South Asia. …”

A Systematic Review on the Advancement in the Study of Fuzzy Variational Problems by Mansi Verma, Chuei Yee Chen, Adem Kılıçman, Risman Mat Hasim

“…In this paper, we provide a systematic review to recap the history of variational principle in the calculus of variations and compare it with the existing techniques in the fuzzy setting. We begin with the preliminary concepts and definitions of fuzzy theory and scrutinize the Euler-Lagrange’s strategy via systematically searched studies concerning fuzzy variational problems to highlight the importance of improving the existing methods. …”

Periodic Solution for a Max-Type Fuzzy Difference Equation by Changyou Wang, Jiahui Li

“…The paper is concerned with the dynamics behavior of positive solutions for the following max-type fuzzy difference equation system: xn+1=maxA/xn, A/xn−1, xn−2, n=0,1,2,…, where xn is a sequence of positive fuzzy numbers, and the parameter A and the initial conditions x−2, x−1, x0 are also positive fuzzy numbers. Firstly, the fuzzy set theory is used to transform the fuzzy difference equation into the corresponding ordinary difference equations with parameters. …”

An Analysis of the Long-Term Sustainability of the Large Companies Included in the Original Standard and Poor’s 500 Index by Jorge Moya, Marta Torres, Manuel Uche-Soria

“…After locating the surviving companies, this paper studied the presence of elements of business quality in each of these firms. Then, using a fuzzy set methodology, this study obtained results that identified some of the main elements that might be considered as inductors of the business durability in the case of the big corporations: the effectiveness of the companies, the coherence with the mission, and the capacity of organisation are essential for the long-term sustainability of the companies especially if they are associated with a formalised structure of governance. …”
