How Hybrid Work Shapes Communication Ties: The Role of Concern about Relationship Loss and Organizational Identification

Journal of Management Studies, EarlyView.
Abstract The rapid shift to hybrid work settings has raised concerns about decreased workplace interactions and communication ties. Based on Need‐to‐Belong Theory, this study extends previous research by adopting the concept of ‘concern about relationship loss’ to explore when and how hybrid work leads to the retention of work‐related communication ...

A Koopman Operator Tutorial with Othogonal Polynomials

, 2022
The Koopman Operator (KO) offers a promising alternative methodology to solve ordinary differential equations analytically. The solution of the dynamical system is analyzed in terms of observables, which are expressed as a linear combination of the ...

Religious Pluralism and Social Networks: How Exposure to Religious Pluralism Through Social Ties Influences Baptism Decisions

Journal for the Scientific Study of Religion, EarlyView.
ABSTRACT A longstanding debate in the sociology of religion has focused on how religious pluralism affects religious participation. Existing research shows mixed findings, often relying on macro‐level measures that overlook how individuals are actually exposed to religious pluralism in their lives. This study shifts focus to the meso‐level by examining

Band‐Pass Filtering With High‐Dimensional Time Series. A Synthetic Indicator of the Medium‐to‐Long Run Component of Growth

Journal of Time Series Analysis, EarlyView.
ABSTRACT The paper deals with the construction of a synthetic indicator of economic growth, obtained by projecting a quarterly measure of aggregate economic activity, namely gross domestic product (GDP), into the space spanned by a finite number of smooth principal components, representative of the medium‐to‐long‐run component of economic growth of a ...

The effects of perspective‐taking on multiple dimensions of discrimination: Can one size fit all?

Political Psychology, EarlyView.
Abstract Perspective‐taking reduces discrimination, but research has taken a one‐size‐fits‐all approach, focusing on single attributes triggering discrimination, particularly ethnic origin, and has paid insufficient attention to heterogeneous treatment effects.

Mathematical model of the zebrafish ventricular cardiomyocyte action potential and calcium transient

The Journal of Physiology, EarlyView.
Abstract figure legend This study presents the development and validation of the first biophysically detailed computational model of the zebrafish ventricular action potential (AP). The model is based on a human cardiomyocyte framework and reparameterized using published and newly generated patch‐clamp recordings of zebrafish ionic currents.
