sources include problems related to peoples that suffered Stalinist repressions, social and economic problems provoking tensions between different communities, and the situation in Chechnya and the associated terrorist attacks with resulting hostility towards people from the Caucasus and Central Asia, which takes the form of discrimination and overt racism towards the groups in question. Committee of Ministers of the Council of Europe in May 2007 expressed concern that Russia still has not adopted comprehensive anti-discrimination legislation, and the existing anti-discrimination provisions are seldom used in spite of reported cases of discrimination. As Gil-Robles noted in 2004, minorities are generally represented on local and regional authorities, and participate actively in public affairs. Gil-Robles emphasized the degree of co-operation and understanding between the various nationalities living in the same area, as well as the role of regional and local authorities in ethnic dialogue and development. Along with that, Committee of Ministers in 2007 noted certain setbacks in minority participation in public life, including the abrogation of federal provisions for quotas for indigenous people in regional legislatures. Although the Constitution of the Russian Federation recognises Russian as the official language, the individual republics may declare one or more official languages. Most subjects have at least two – Russian and the language of the "eponymous" nationality. As Ministers noted in 2007, there is a lively minority language scene in most subjects of the federation, with more than 1,350 newspapers and magazines, 300 TV channels and 250 radio stations in over 50 minority languages. Moreover, new legislation allows usage of minority languages in federal radio and TV broadcasting. In 2007, there were 6,260 schools which provided teaching in 38 minority languages. Over 75 minority languages were taught as a discipline in 10,404 schools. Ministers of the Council of Europe have noted efforts to improve the supply of minority language textbooks and teachers, as well as greater availability of minority language teaching. However, as Ministers have noted, there remain shortcomings in the access to education of persons belonging to certain minorities. There are more than 2,000 national minorities' public associations and 560 national cultural autonomies, however the Committee of Ministers has noted that, in many regions, the amount of state support for the preservation and development of minority cultures is still inadequate. Alvaro Gil-Robles noted in 2004 that there is a significant difference between "eponymous" ethnic groups and nationalities without their own national territory, as resources
