Haldy (odvaly), které na Ostravsku vznikaly jako průvodní jev dolování černého uhlí v první polovině 20.stol, se již staly typickým krajinným prvkem této oblasti. Později zde byly snahy dolováním pozměněnou krajinu „uzdravit“ finančně nákladnými technickými rekultivacemi. Výstupy z našich studií prokázaly, že spontánní sukcese na nerekultivovaných haldách probíhá rychleji a společenstva bezobratlých jsou zde lépe strukturovaná. Navíc nerekultivované haldy podporují populace ochranářsky cenných druhů bezobratlých. Jednoznačně proto doporučujeme haldy ponechat spontánní sukcesi, před finančně náročnými technicky vedenými rekultivacemi., The spoil heaps in Ostrava were created during mining of black coal in the first half of the 20th century. Later, there were efforts to “heal” the landscape by technical reclamations, which are rather expensive. Our studies showed that spontaneous succession on non-reclaimed spoil heaps is faster then succession on their reclaimed counterparts. The communities of invertebrates on non-reclaimed spoil heaps are also more mature and contain rare species in comparison with the reclaimed ones., and Jiří Hodeček, Tomáš Kuras.
The article examines the Czech educational praxis toward integration of immigrant children. Although the number of immigrant children increased during past several years, Czech national educational policy still lacks specific measures which would systematically promote inclusive education and integration of immigrant children. The article aims to describe the experience of schools with integration of immigrant children at schools, and to identify the most important barriers that prevent full participation of immigrant children according to accounts of interviewees. Based on 21 in-depth interviews with representatives of school staff in 11 Prague public-sector základní škola (ISCED 1+2) with higher share of immigrant children (5-20 %), the paper provides insight into diverse into the ways how schools deal with immigrant children, families´ acculturation strategies and inclusive educational policy. The article concludes with a discussion of “immigrant paradox”, highly achieving minorities (particularly Vietnamese students)., Kateřina Vojtíšková., and Obsahuje seznam literatury
