Compatible mappings and common fixed points

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
A generalization of the commuting mapping concept is introduced. Properties of this “weakened commutativity” are derived and used to obtain results which generalize a theorem by Park and Bae, a theorem by Hadzic, and others.

Developing a Z‐ESG Score Model for Assessing Corporate ESG Performance

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT In this study we develop a novel, unique ESG rating model that exploits the logic of the Z‐score by Altman (1968) to discriminate between ESG performing and non‐ESG performing firms using indicators of ESG performance for each of the three pillars (Environmental, Social, Governance) in place of financial ratios.

Functionality and quality of life in different gestational trimesters: A cross‐sectional study

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To compare functionality and quality of life in pregnant women in different trimesters. Methods An observational cross‐sectional study was conducted with pregnant women ≥18 years of age undergoing prenatal care. Data were collected using a sociodemographic questionnaire, the WHO Quality of Life questionnaire (WHOQOL‐Bref), WHO ...

Coincidence theorems for some multivalued mappings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
Two coincidence theorems in a metric space are proved for a multi-valued mapping that commutes with a single-valued mapping and satisfies a general multi-valued contraction type condition.

Land Use Policy and Racial Segregation

open access: yesInternational Studies of Economics, EarlyView.
ABSTRACT Land use policies, though seemingly race‐neutral, can inadvertently contribute to racial segregation. Our study focuses on examining the impact of minimum lot size regulations on the likelihood of ethnic minorities integrating into a community, which reveals compelling evidence suggesting that black households exhibit a preference for smaller ...

Common Fixed Points and Invariant Best Approximations in 2-Banach Spaces

open access: yesAcademic Science Journal
In this paper, we introduce and study the concepts of 2-f-contraction and 2-f-nonexpansive mappings in the framework of 2-normed spaces. The main objective is to generalize classical contraction-type mappings and provide an effective approach ...

Deniers and Compliers: Unpacking the Heterogeneous Effectiveness of U.S. Stay‐at‐Home Mandates During the COVID‐19 Pandemic

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT While existing work shows COVID‐19 stay‐at‐home (SAH) policies decreased mobility on average, we lack evidence regarding heterogeneity in policy effectiveness across US counties. To uncover potential heterogeneity, we implement a novel two‐stage approach.

Some Novel Fixed-Point Results in Neutrosophic Soft Metric Space With Application in Decision-Making to Select the Optimal Adsorbent

open access: yesJournal of Mathematics
In this research paper, the concepts of compatible maps and maps of type α¯ and (β¯) within the framework of neutrosophic soft metric spaces (NSMS) are established. The interconnections between α¯- and (β¯)-type maps are also clarified. Additionally, the
