Subject. The article discusses medical and demographic processes in Russia and Finland. Objectives. I evaluate cases of social innovations implemented for the preservation and strengthening of public health in Finland under the auspices of The Global Burden of Disease Study. Methods. Methodologically, the study relies upon the ideology of the GDB Project, which rests on the DALY (the Disability Adjusted Life Year). Results. I analyzed the morbidity and mortality rates, DALY in Russia and Finland, determined what mainly triggers the risk (environmental, behavioral, metabolic) fueling some public health degradation. The article provides the insight into the efficiency of some social innovations implemented in Finland and suggests what should be done to outline medical and demographic programs in Russia. Conclusions and Relevance. The medical and demographic situation in Russia requires new tools to find innovative solutions for the social policy and, inter alia, the use of the GBD technique, which proved to be effective. Referring to evidence from Finland, demographic challenges in Russian can be handled through a systems approach, i.e. socio-economic actions, improvement of the healthcare and social security, wellness propaganda.

Subject. This study focuses on the Finno-Ugric peoples carrying unique cultural customs and traditions. Objectives. I evaluate how various factors influence the demographic development of the Finno-Ugric peoples. Methods. Analyzing the current situation, I refer to official statistics and the Health for All database of the World Health Organization, statistical yearbooks of the Russian State Statistics Service. All data were organized as a special information system including several related blocks, such as economic development of locations, demographic situation, health and healthcare. Research was based on the comparative analysis of key medical-demographic and socio-economic indicators, and economic-mathematical apparatus. Results. I comprehensively evaluated the current situation macro- and mesoeconomically by gradually shifting from the comparison of countries to regional trends. I traced patterns of medical and demographic processes in the Finno-Ugric countries, such as Hungary, Finland and Estonia, and national autonomies across Russia. Conclusions and Relevance. I discovered that there is a certain relationship between a man and environment that translate into physical and physical health of people. They should be taken into consideration when outlining demographic development programs. The findings can be used to prepare regional medical and demographic documents, including the prevention of suicidal behavior and alcoholism and general medical services.

Americans’ attitudes toward same-sex relationships have liberalized considerably over the last 40 years. We examine how the demographic processes generating social change in attitudes toward same-sex relationships changed over time. Using data from the 1973 to 2018 General Social Survey and decomposition techniques, we estimate the relative contributions of intracohort change and cohort replacement to overall social change for three different periods. We examine (1) the period prior to the rapid increase in attitude liberalization toward same-sex marriage rights (1973–1991), (2) the period of contentious debate about same-sex marriage and lesbian and gay rights (1991–2002), and (3) the period of legislative and judicial liberalization at the state and federal levels (2002–2018). We find that both intracohort and intercohort change played positive and significant roles in the liberalization of attitudes toward same-sex relationships in the postlegalization period, but that individual change was more important than population turnover over this period.

AbstractExtrapolating patterns from individuals to populations informs climate vulnerability models, yet biological responses to warming are uncertain at both levels. Here we contrast data on the heating tolerances of fishes from laboratory experiments with abundance patterns of wild populations. We find that heating tolerances in terms of individual physiologies in the lab and abundance in the wild decline with increasing temperature at the same rate. However, at a given acclimation temperature or optimum temperature, tropical individuals and populations have broader heating tolerances than temperate ones. These congruent relationships implicate a tight coupling between physiological and demographic processes underpinning macroecological patterns, and identify vulnerability in both temperate and tropical species.

The future of Ukraine is children, the future of demographic processes largely depends on their number, their health. The main role in the child's life is played by the dynamic process of growth and biological maturation, where one of the informative indicators is the cardiovascular system. In case of severe discomfort in the body, it is necessary to stop classes and consult a doctor. All physical activity must correspond to the physical fitness and age of the children. The cycling module is designed for 24 hours, according to the schedule, two physical education lessons were paired. For an effective lesson. In the course of the lessons, they mastered theoretical information (10 %), general and special physical training (20 %), technical training (70 %). During physical culture classes using a bicycle, objective factors were taken into account, such as the availability of a sports ground for technical riding, equipment (30 bicycles), and the weather conditions of the region. Over the course of one and a half months, the conducted classes formed the necessary skills for safe cycling, technical skill in children of 10-11 years old, provided the necessary foundation for physical fitness and motivation to go in for sports. The increase in adaptive indices of the heart was 14 % in grade 5-A, 8 % in grade 5-B, and 15 % in grade 5-V of the total number of children in each grade. This indicates that muscular work took place with positive consequences for the functional state of the body of children aged 10-11 years.
