Irregularity in Daily Activities Predicts Depression via Reduced Perceived Control: A Daily Diary Study

Journal of Clinical Psychology, EarlyView.
ABSTRACT Objectives Disruptions in social rhythm—referring to irregularities in daily activities such as meals, work, and social interactions—have been associated with increased psychological distress, including depression. While circadian rhythm‐related factors (e.g., sleep quality) have been proposed as key mechanisms underlying this link, emerging ...

Comparisons of Estimation Procedures for Nonlinear Multilevel Models

Journal of Statistical Software, 2003
We introduce General Multilevel Models and discuss the estimation procedures that may be used to fit multilevel models. We apply the proposed procedures to three-level binary data generated in a simulation study. We compare the procedures by two criteria,

Toward an idiographic understanding of the role of sleep‐mood dynamics in adolescents' internalizing symptoms

JCPP Advances, EarlyView.
Abstract Background Adolescence is marked by increased vulnerability to sleep disturbances and mood disorders. Understanding how day‐to‐day changes in sleep and mood are linked within the same individual is crucial for clarifying sleep's role in emerging internalizing disorders. However, the extent to which an adolescent's fluctuations in sleep predict

Central Limit Theorem for the Multilevel Monte Carlo Euler Method and Applications to Asian Options [PDF]

, 2012
This paper focuses on studying the multilevel Monte Carlo method recently introduced by Giles [8] and significantly more efficient than the classical Monte Carlo one. Our aim is to prove a central limit theorem of Lindeberg Feller type for the multilevel

Multilevel Monte Carlo Approaches for Numerical Homogenization [PDF]

Multiscale Modeling & Simulation, 2015
In this article, we study the application of Multi-Level Monte Carlo (MLMC) approaches to numerical random homogenization. Our objective is to compute the expectation of some functionals of the homogenized coefficients, or of the homogenized solutions. This is accomplished within MLMC by considering different levels of representative volumes (RVE), and,

As Seen on Social Media: The Daily Effects of Social Media Content on Employee Emotions and Behaviors

Journal of Organizational Behavior, EarlyView.
ABSTRACT Employees regularly use social media during work hours and thus are exposed to a wide variety of vibrant, fluid social information that they would likely not have access to through other channels. We contribute to the literature by suggesting that the social information available on social media is infused with meaning that can affect ...

Avoiding Moral Divergence: A Self‐Verification Perspective on Why and When Team Ethical Conflict Inhibits Individual Ethical Voice

Journal of Organizational Behavior, EarlyView.
ABSTRACT Although contextual factors have been shown to facilitate ethical voice, research on team‐level antecedents that may inhibit it has been limited. Drawing on self‐verification theory, we develop a multilevel moderation–mediation model that examines how team ethical conflict inhibits individual ethical voice. Ethical self‐verification perception
