In recent years, many countries have revised their school policy documents to incorporate digital competence, computational thinking and programming.This study examines and compares how and in what contexts Nordic curricula, Swedish and Norwegian in particular, embody aspects of computational thinking.Results show that only parts of the practices d
The economic voting literature mako shark toys disagrees over the exogeneity of economic perceptions on individual electoral behavior.One side argues that economic perceptions are driven by partisan dispositions, which then calls into question the substantive importance of this factor in assessing electoral behavior.A second side argues that voters
The thermal insulation effect of snow on the active layer thickness of permafrost cannot be ignored.Under the dual influence of snow cover and roadbed construction, this paper studies the influence of snow cover on the temperature field and permafrost upper limit under the permafrost roadbed in the alpine mountains.Through the application of PDE mo
