On two new means of two arguments III [PDF]
, 2017 In this paper authors establish the two sided inequalities for the following two new means $$X=X(a,b)=Ae^{G/P-1},\quad Y=Y(a,b)=Ge^{L/A-1}.$$ As well as many other well known inequalities involving the identric mean $I$ and the logarithmic mean are ...

Low‐Carbon Transition and Active Management: Evidence From Emerging Market Funds
Business Ethics, the Environment &Responsibility, EarlyView.ABSTRACT Previous literature finds mixed evidence on the performance of emerging mutual funds and how investors are becoming more aware of investing in companies involved in low‐carbon emission activities. Given the opportunities that emerging markets and sustainable investing offer to active management, this study aims to fill a gap in the literature ...

Reliability measures in knowledge structure theory
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract In knowledge structure theory (KST) framework, this study evaluates the reliability of knowledge state estimation by introducing two key measures: the expected accuracy rate and the expected discrepancy. The accuracy rate quantifies the likelihood that the estimated knowledge state aligns with the true state, while the expected discrepancy ...

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

Improved Young and Heinz inequalities with the Kantorovich constant
, 2015 In this article, we study the further refinements and reverses of the Young and Heinz inequalities with the Kantorovich constant. These modified inequalities are used to establish corresponding operator inequalities on Hilbert space and Hilbert-Schmidt ...

British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Hidden Markov diagnostic classification models capture how students' cognitive attributes evolve over time. This paper introduces a Bayesian Markov chain Monte Carlo algorithm for diagnostic classification models that jointly estimates time‐varying Q matrices, latent attributes, item parameters, attribute class proportions and transition ...

Spanish stock returns, growth, and inflation, 1900–2020
The Economic History Review, EarlyView.Abstract This paper studies equity returns in the Madrid Stock Exchange and their connections with the macroeconomy from the emergence of a stock market around 1900 to its ‘big bang’ at the turn of the twenty‐first century. Using high‐quality data from primary sources and the methodology of the modern IBEX35 (published since 1987), we constructed an ...

Journal of MathematicsIn this paper, we present a new approach to construct fractional 2-point right Radau type integral inequalities using a novel identity, for functions with s-convex first derivatives in the second sense via Riemann–Liouville fractional integral operators.

Speculation in the United Kingdom, 1785‒2019
The Economic History Review, EarlyView.Abstract Speculation has long been thought to have significant economic effects, but it is difficult to measure, making it challenging to examine these effects empirically. In this paper we measure speculation in the United Kingdom since 1785 by using business and financial reporting in The Times newspaper.
