Dynamic Characteristics of Medical and Demographic Indicators of Public Health in Arkhangelsk Oblast in the First Twenty Years of the XXI Century: Retrospective Analytical Descriptive Study

Background. Assessing the dynamic characteristics of basic public health indicators is essential to ensure the sustainable human development, quality of life and health care system performance in the Arctic and Subarctic regions of Russia. The study is based on the need for constant monitoring of the medical and demographic situation in order to provide timely correction of measures for improving the health care system performance.Objective — to assess the trends in basic medical and demographic indicators characterizing the population health of the Arkhangelsk Oblast. Target population: population of the Arkhangelsk Oblast, no impacts, no outcomes.Methods. Criteria for sample or group formation: the research was performed by means of a continuous method based on the study of population of medical and demographic events. The main inclusion criterion was the availability of information about a medical and demographic event in the Arkhangelsk Oblast in the Russian Fertility and Mortality database (RusFMD), the database of the Federal State Statistics Service (Rosstat). Estimated parameters: life expectancy, infant mortality, disability, morbidity, natural population growth and chronicity rates related to the population of the Arkhangelsk Oblast excluding the Nenets Autonomous Okrug. The study was conducted between 2021 and 2022. The following measurement methods were used: autoregressive and integrated moving average, Irwin method to identify abnormal values, linear regression, time series dynamics, and method of chain substitutions. The research was performed by means of a continuous method based on studying the population of medical and demographic events.Results. Natural population growth and chronicity rates showed a stable negative trend, which indicated a decrease in the reproduction potential of the population, and an increase in chronic forms of diseases. Life expectancy, primary morbidity, and primary disability demonstrated a positive trend, but with a tendency to exhaust the positive potential. Infant mortality was the only indicator that consistently showed a positive trend. No additional results of the research were reported.Conclusion. The results of the study demonstrated the deterioration in population health of the Arkhangelsk Oblast, which may be due to a decline in living standards and quality of life as well as to a decrease in health care system performance and a rise in its dysfunctionality. The study has no limitations

The influence of the disordered dipole subsystem on the thermal conductivity of the CO solid at low temperatures

The thermal conductivity of solid CO was investigated in the temperature range 1–20 K. The experimental temperature dependence of thermal conductivity of solid CO was described using the time-relaxation method within the Debye model. The comparison of the experimental temperature dependences of the thermal conductivity of N₂ and CO shows that in the case of CO there is an additional large phonon scattering at temperatures near the maximum. The analysis of the experimental data indicates that this scattering is caused by the frozen disordered dipole subsystem similar to a dipole glass. The scattering is described by the resonant phonon scattering on tunnelling states and on low-energy quasi-harmonic oscillations within the soft potential model

The heat capacity of nitrogen chains in grooves of single-walled carbon nanotube bundles

The heat capacity of bundles of closed-cap single-walled carbon nanotubes (SWNT) with one-dimensional chains of nitrogen molecules adsorbed in the grooves has been first experimentally studied at temperatures from 2K to 40K using an adiabatic calorimeter. The contribution of nitrogen C(T) to the total heat capacity has been separated. In the region 2-8K the behaviour of the curve C(T) is qualitatively similar to the theoretical prediction of the phonon heat capacity of 1D chains of krypton (Kr) atoms localized in the grooves of SWNT bundles. Below 3K the dependence C(T) is linear. Above 8K the dependence C(T) becomes steeper in comparison with the case of Kr atoms. This behaviour of the heat capacity C(T) is due to the contribution of the rotational degrees of freedom of the nitrogen molecules.Comment: 15 pages, 4 figure

Le pluralisme politique à l’épreuve de la vie privée : entre normes et pratiques

L’espace des relations interpersonnelles et privées, en tant qu’espace de politisation et d’expression des choix politiques, est peu connu. C’est à une meilleure connaissance du « citoyen privé » et de la « politisation intime » que cet article veut contribuer, en étudiant les ressemblances et les divergences idéologiques au sein du cercle des proches. Présentant les résultats d’une enquête quantitative et représentative de la population française inédite, « Famille, amour et politique », réalisée par le CEVIPOF, il examine la filiation, la conjugalité, et l’amitié et montre les interactions et les transactions qui opèrent entre le système des normes et le système des affects des individus. La famille apparaît plus hétérogame politiquement tandis que le couple et le cercle des amis sont plus homogames. Toutefois, c’est le niveau de politisation des individus qui est en dernière instance le plus déterminant. Une affiliation politique affirmée, et tout particulièrement à gauche, ainsi qu’un intérêt marqué pour la politique, renforcent toujours l’homogamie politique au sein du cercle des proches, dans les principes comme dans les faits. Plus largement, l’article ouvre une réflexion sur l’espace de la vie privée en tant que terrain d’expérience des conditions de la pluralité démocratique.Little is known of the role played by private interpersonal relationships in politicization and the expression of political choices. This article aims to improve our understanding of “private citizens” and “personal politicization” through a study of ideological similarities and divergences within family and friendship circles. The analysis, based on findings from an unprecedented quantitative representative French population survey by the CEVIPOF (Center for the study of French political life) entitled “Famille, amour et politique” [Family, love and politics], examines filiation, conjugality and friendship, showing the interactions and transactions that take place between the system of norms and the system of individual feelings. Families appear more heterogamous politically, while couples and friendship circles are more homogamous. However, individuals’ level of politicization is ultimately the most determinant factor. Having a strong political affiliation, particularly on the left of the political spectrum, and a strong interest in politics always strengthens intra-circle political homogamy in terms of both principles and actions. At a more general level, the article reflects on the sphere of private life as a field for the development of conditions of democratic pluralism
