Third-Order Differential Subordination Features of Meromorphic Functions: Erdelyi–Kober Model Integral Operator Application

Axioms
This study is concerned with the class of p-valent meromorphic functions, represented by the series f(ζ)=ζ−p+∑k=1−p∞dkζk, with the domain characterized by ...

On applications of differential subordination and superordination

Tamkang Journal of Mathematics, 2008
In the present investigation we obtain the sufficient conditions for normalized analytic functions $f$ to satisfy$$ q_1 \prec \frac{f^2}{z^2f'} \prec q_2, $$where $ q_1 $ and $ q_2 $ are univalent functions with $ q_1(0)= q_2(0)=1 $. Also we obtain the sandwich results involving Carlson-Shaffer linear operator, $ S\u{a}l\u{a} $gean derivative and ...

Application of Differential Subordinations to the Arithmetic–Geometric Means by Using an Operator

Journal of Mathematics, Volume 2025, Issue 1, 2025.
This study investigates differential subordination involving arithmetic and geometric mean approaches associated with a previously introduced operator. While earlier studies considered cases where the dominant function was convex or linear, the present work extends these results by examining differential subordinations for specific classes of convex ...

Sign language in d/deaf students' spoken/written language development: A research synthesis and meta‐analysis of cross‐linguistic correlation coefficients

Review of Education, Volume 12, Issue 3, December 2024.
Abstract This paper presents the first systematic review and meta‐analysis on cross‐linguistic correlations between sign language and spoken/written language competences in bilingual d/Deaf learners. A total of 202 effect sizes were identified based on 70 independent samples that appeared in 52 studies from 1981 to 2023 (N = 3570).

Fractional differential superordination

Tamkang Journal of Mathematics, 2014
The notion of differential superordination was introduced by S.S. Miller and P.T. Mocanu as a dual concept of differential subordination. Recently, in Tamkang J. Math.[7], the author have introduced the notion of fractional differential subordination.

Testing the Relationship of Linguistic Complexity to Second Language Learners’ Comparative Judgment on Text Difficulty

Language Learning, Volume 74, Issue 3, Page 672-706, September 2024.
Abstract This study examined the relationship of linguistic complexity, captured using a set of lexical richness, syntactic complexity, and discoursal complexity indices, to second language (L2) learners’ perception of text difficulty, captured using L2 raters’ comparative judgment on text comprehensibility and reading speed. Testing materials were 180

On certain differential sandwich theorems involving a generalized Sǎlǎgean operator and Ruscheweyh operator

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
In the present paper we introduce sufficient conditions for subordination and superordination involving the operator DRλm,n$DR_\lambda ^{m,n} $ and also we obtain sandwich-type results.

Concept‐Driven Sociology

Symbolic Interaction, Volume 47, Issue 2, Page 123-141, May 2024.
Excerpted from my book Generally Speaking, this paper introduces “concept‐driven sociology,” a special way of theorizing designed to reveal abstract social patterns. As such, it examines the methodological process by which we can “distill” generic patterns from the culturally, historically, and situationally specific contexts in which we encounter them.

Application of Fuzzy Subordinations and Superordinations for an Analytic Function Connected with $\mathfrak{q}$-Difference Operator

Axioms
This paper extends the idea of subordination from the theory of fuzzy sets to the geometry theory of analytic functions with a single complex variable. The purpose of this work is to define fuzzy subordination and illustrate its main characteristics. New

Referential Cohesion, Ambiguity, Vagueness and Generality in Parliamentary Debate*

Studia Linguistica, Volume 78, Issue 1, Page 128-155, April 2024.
Abstract Political discourse has been characterised as being ‘vague’ and ‘ambiguous’. It is argued that politicians tend to use generic and unspecific words in order to avoid explicit commitment (McGee 2018). Although this situation may describe discourse genres such as political interviews and election debates, it is unclear that it can be applied to ...
