A method for analysis of the dynamics of macroeconomic indicators based on the model of a piecewise trend for economies of unstable growth is proposed. The relevance of the article is supported by the absence of adequate mathematical models and the inadequacy of traditional continuous models to describe the features of economic dynamics of this type. Its application is demonstrated on the examples of Ukraine, Greece and Italy in comparison with stable developing countries of Eastern Europe -the Czech Republic, Slovakia and Poland. In the process of approbation new indices of instability based on this model have been developed. A higher degree of conformity of the proposed model is proved in comparison with traditional continuous models not only for countries with signs of unstable economic dynamics, but also for some countries with stable economies. During approbation, a new index of instability of growth was developed based on this piecewise linear trend model. The indices of instability of growth were calculated for 43 European countries for the period from 1989 to 2019 and their rating was built.

The implementation of qualitative inclusion in higher education institutions is one of the conditions for the constant development of Ukraine. The analysis of statistical data, made by the authors, shows a permanent reduce of the number of people with disabilities, who obtain higher education now. Based on the analysis of modern researches and media materials, authors identify the reasons for this tendency. They believe that one of the main barriers is the inability of young people with disabilities to get a job in their specialty and build a successful professional trajectory. Having analyzed the few of Ukrainian universities’ websites, authors propose the development of a unified approach for the special educational services provision. Authors also determine its main elements as: definition of educational difficulties; systematic monitoring of the availability of higher education institutions and of the level of satisfaction of special educational services; expansion of the collected information about students with disabilities; programs of communication ethics among teachers, students and persons with disabilities; psychological services; monitoring the observance of the rights of students with disabilities; inclusion of students with disabilities in academic mobility programs; employment of students with disabilities; determination of quality indicators for the special educational services provision; providing full information on the possibility of provision services to students with disabilities; representation of students with disabilities in the advertising products of institutions – as equal members of the student community. The authors consider these elements as an appropriate base for determination of the quality of higher education institutions inclusion. At the same time, teachers use the individual approach, adjusting a system of «smart adaptation» for students with different physiological and psychological characteristics.
