On the Reducibility of Weighted Composition Operators Generated by Periodic Transformations
In this article, we study the reducibility of weighted composition operators (also known as weighted displacement operators) acting on Banach spaces of continuous functions on a compact topological space X. We consider operators of the form Bu(x) = a(x)u(α(x)), where α : X⟶X is a continuous mapping and a is a continuous function.

Approximation properties by Schurer type q-Kantorovich–Stancu shifted knots operators
We design the Schurer type Kantorovich–Stancu operators by using shifted knots in the quantum calculus. We obtain the convergence and other related approximation properties of these operators.

On the Approximation Process of Shifted‐Knots Bivariate Stancu‐Type Kantorovich Operators
This paper focuses on defining bivariate Stancu‐type Kantorovich operators with the technique associated with the idea of shifted knots. The degree of approximation and weighted approximation of these bivariate operators are estimated, respectively, by means of Lipschitz kind bivariate functions and weighted functions of two variables. Furthermore, the

In this work, we investigate some approximation properties of blending type univariate and bivariate Schurer-Kantorovich operators based on shape parameter λ ∈ [−1, 1]. We evaluate some moment estimates and obtain several direct theorems.

Household Portfolios and Monetary Policy
ABSTRACT We show that expansionary monetary policy is positively (negatively) associated with household portfolio allocation to high‐risk (low‐risk) assets, in line with ‘reaching for yield’ behaviour. Our main findings are based on an analysis of US household‐level data using alternative measures of monetary policy shifts over the period 1999–2007 ...

STADTMITTE UMSTEIGEN? HEINZ KNOBLOCH AND THE ‘ARCHAEOLOGICAL’ TRACES OF BERLIN'S GHOST STATIONS
ABSTRACT In 1982, the East German journalist Heinz Knobloch published a volume entitled Stadtmitte umsteigen. Its title was provocative: since the construction of the Berlin Wall, it had not been possible to change trains at Stadtmitte in East Berlin, as one of the two lines functioned only as a transit route between the north and south of West Berlin.

Pointwise approximation by a Stancu variant of Durrmeyer-Schurer operators
In the present paper, we introduce a kind of Stancu variant of Durrmeyer-Schurer operators which includes non-negative real parameters α and β, and obtain the direct and converse results of approximation by the operators.

The behavior of a new modification of operators of the Baskakov–Schurer–Stancu variant is discussed in this study. First, we establish certain necessary moment and central moment estimates.

ABSTRACT This study utilizes data from seven waves of the Survey of Consumer Finances to investigate how financial planning advice moderates the relationship between self‐reported financial risk tolerance and two aspects of investment behavior: stock market participation and the proportion of financial wealth allocated to stocks.
