Item Towards the abyss: the influence of parents’ alcoholism on the development in adolescence(Lviv Polytechnic Publishing House, 2015) Khomik, Khrystyna; Honcharenko, Yelyzaveta; Lviv Polytechnic National UniversityThe article presents a theoretical overview of the problem of deviations in adolescents who are determined by alcohol dependent parents. The behavior of alcohol dependent parents or one of them creates an atmosphere in the family, which inevitably creates resistant and mental sets in adolescents on the consumption of alcohol and updates the assimilation of norms and stereotypes of deviant behavior. The results of systematic use of alcohol that are manifested in the family, less visible to the public, but the nature and depth of its actions are the most dangerous and harmful. So, the most difficult consequences of alcohol dependence of parents for adolescents are the following: 1) the desire to consume alcohol; 2) increase in aggression and conflict, irresponsibility, which eventually can lead to antisocial behavior; 3) the emergence of vagrancy as a form of deviant behavior.Item Physical education for people living with HIV: the concept and legal basis(Lviv Polytechnic Publishing House, 2015) Nikitin, Nikita; Pelmenev, Victor; Nikitina, Anastasiya; Avakyan, Michael; Immanuel Kant Baltic Federal UniversityThe article concerns juridical aspects of the rehabilitation for people with HIV infection.
