Mental health measures among adolescents in 12 low‐ and middle‐income countries: Measurement invariance and cross‐sectional analyses of Disrupting Harm survey data

JCPP Advances, EarlyView.
Abstract Background Nationally representative mental health data in adolescents from low‐ and middle‐income countries (LMICs) are scarce. This study aimed to examine mental health and wellbeing indicators amongst adolescents in 12 LMICs across Eastern and Southern Africa and Southeast Asia. Methods We conducted a secondary analysis of data involving 12,

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

Do Product Market Reforms Work? Assessing Regulatory Changes Impacting Competition

Southern Economic Journal, EarlyView.
ABSTRACT We create a new dataset that characterizes studies of product market reforms implemented from 1932 to 2011. We examine the size and origins of differences in estimated impacts based on an OECD classification scheme for potentially competitive restrictions of regulation. The median impact from switching to a pro‐competitive environment is a 19%
