Effects of Vector Density on Blood Parasite Spread and Health Consequences for Avian Hosts: An Experimental Epidemiology Blueprint

open access: yesIntegrative Zoology, EarlyView.
In an experimental epidemiology setup, groups of pigeons were exposed to different numbers of infective malaria vectors. Vector number explained the speed of transmission, the final prevalence, and changes in host behavior. ABSTRACT Vector density plays a critical role in the transmission dynamics of vector‐borne diseases and thus in their health and ...

Using Lorenz curves to represent firm heterogeneity in Cournot games [PDF]

open access: yes
We derive several comparative-static results for Cournot games when firms have nonconstant marginal-cost curves which shift exogenously. The results permit us to rank certain vectors of equilibrium marginal costs with the same component sum according to ...

We estimated: (1) whether the distribution of cannabis use frequency was stable over time; (2) whether changes in average cannabis use were mirrored across consumption quantiles; and (3) whether higher average use ...
