Motivated by the impact of temporal heterogeneity of human activities on epidemic spreading, this paper studies the susceptible-infected model on a fu...

We use panel data for 115 countries over the period 1995–2016 to model heterogeneity of debt-growth nexus along with underlying factors that might explain it. The grouped fixed effect (GFE) estimator is used endogenously classify into groups and a multinomial logit employed explore drivers detected heterogeneity. GFE classifies five which debt has different impacts on growth. According our resu...

Health is a comprehensive phenomenon with many determinants. The influence of environmental conditions on human health poses challenges for public scientists. One the main issues availability and relevance data health, including such indicators as morbidity decease prevalence. In this study, we overcome obstacle by using micro self-reported from Russia Longitudinal Monitoring Survey Higher Scho...

Abstract Heterogeneous distributions are a fundamental principle of ecology, manifesting as natural variability within ecological levels organization from individuals to ecosystems. In disease in biotic and abiotic factors can result heterogeneous patterns transmission virulence—broadly defined here the negative consequences infection. Still, our classic theoretical understanding dynamics comes...
