Much of the analysis of economic growth has focused on the study of aggregate output. Here, we deviate from this tradition and look instead at the structure of output embodied in the network connecting countries to the products that they export. We characterize this network using four structural features: the negative relationship between the diversification of a country and the average ubiquit...

BACKGROUND Stress-related mental disorders (SRMD), which correspond to the diagnostic code F43 in the International Classification of Diseases, version 10, rank among the leading causes of sickness absence in several European countries. Despite the size of this health problem, research on risk factors for severe medical outcomes, like suicidal behavior, is lacking to date. The aim of this study...

Abstract. Seasonal variability of non-refractory PM1 (NR-PM1) was studied at a rural background site (National Atmospheric Observatory Košetice – NAOK) in the Czech Republic to investigate effect regional and long-range atmospheric transport central Europe. NR-PM1 measurements were performed by compact time-of-flight aerosol mass spectrometry (C-ToF-AMS), chemically speciated size distributions...

Introduction The threat and preservation of the territorial integrity Ukraine are not new issues. During last decade, peacetime (Peace, until 2013) was disrupted by active hostility (AH, 2014–2015) trench warfare (TW, 2016–2021). War exert acute chronic impacts on mental health, may be a substrate for health disorders, especially worrisome since, today, large-scale conflict has demanded recruit...

BACKGROUND Stress-related mental disorders (SRMD) are common and costly. Rehabilitation strategies, including pharmacotherapy, may be complicated to evaluate. Previous research has indicated increased quality of life and self-rated health for SRMD patients that receive a combination of conventional and complementary therapies, i.e. integrative care. The aim of this retrospective registry study ...

This paper offers a new explanation for why some governments consistently impose such high agricultural tax rates that their revenues decline, and consistently spend what tax revenue they have on things other than productive public investments such as agricultural R&D. We propose an intertemporal political economy model, in which taxes and R&D levels are set in a repeated game between governmen...
