The article presents the construction of an agent-based model of segregation step by step. The article is intended as a tutorial for the reader’s first steps with agent-based modeling. The model is programmed in the NetLogo software and provided in two versions: first as an online executable version, for first-impression purposes, and second as NetLogo code, for serious experiments and further model improvements by the reader. The article describes the user interface and source code of the model in close detail. Most of the article is dedicated to careful, in-depth explanation of the NetLogo code. The model aims to answer Schelling’s classical question: "Is it possible to obtain an ethnically segregated structure of a town with relatively tolerant inhabitants?" The model also aims to answer the question: "Does size of recognized neighbourhood suppress tendency to segregation?" Analysis of the data produced by the model informs us that the tendency to segregation decreased with larger recognized neighbourhood - the larger the neighbourhood the lower the number of inhabitants living in an ethnically homogenous neighbourhood. However, size of recognized neighbourhood did not moderate the relationship between intolerance and tendency to segregation - the slope of the relationship was still the same (or even steeper for larger neighbourhoods)., František Kalvas., and Obsahuje bibliografické odkazy
Táto teoretická stať sa venuje špecifikám vzdelávania detí z menšín a sociálne-znevýhodnených skupín. Vychádza predovšetkým z amerických skúseností so vzdelávaním černošských detí, pretože u nich sa spája skúsenosť viditeľne odlišnej menšiny so skúsenosťou sociálneho znevýhodnenia, a podobne je tomu aj v prípade rómskych detí v Česku. Cieľom práce je spraviť prehľad o jedinečných charakteristikách týchto detí vo vzťahu k ich vzdelávaniu a školskej úspešnosti a v odpovediach na ne hľadať inšpiráciu pre vzdelávanie podobne znevýhodnených detí u nás. Budeme sa venovať dôvodom, prečo deti z menšín dosahujú vo všeobecnosti horšie výsledky než ich rovesníci z majoritnej strednej triedy – pôjde hlavne o ich nadmerné zastúpenie v špeciálnom vzdelávaní, segregáciu, sociálnu konštrukciu školského zlyhania a ich jazykové vzdelávanie. and This theoretical paper deals with the specific issues of education of minority children from socially disadvantaged environments. Its main focus is on the education of African American children, because they are a clearly different minority and often socially disadvantaged, similar to Roma children in Czech society. The aim of this paper is to summarise specific characteristics of these children in relation to their education and the ways they are dealt with in the U.S. context, and then find inspiration for the education of similarly disadvantaged children here. The paper stresses the reasons children from minorities tend to be less successful at school than their counterparts from white middle class families: their excessive segregation in special schooling and 'poor schools', the social construction of their failure, and their language education.
