130 YEARS SINCE THE BIRTH OF ANTON MAKARENKO: REHABILITATION OF A GREAT PEDAGOGUE AND WRITER

Данная публикация представляет собой обзор статьи, вышедшей по случаю юбилея А. С. Макаренко в Эстонском журнале социальной работы (Sotsiaaltöö 4/2018, 79–86). Автор статьи пытается опровергнуть миф о Макаренко как о подвижнике сталинской коллективистской идеологии, жесткой дисциплины и трудового воспитанияThis is a reference to an article from the Estonian journal of social work (Sotsiaaltöö 4/2018, pp 79-86), which was dedicated to the birth anniversary of Anton Makarenko. The author's aim is to refute the myth of Makarenko as a spokesman of stalinist collectivism and severe discipline ideolog

Low temperature scattering with the R-matrix method: the Morse potential

Experiments are starting to probe collisions and chemical reactions between atoms and molecules at ultra-low temperatures. We have developed a new theoretical procedure for studying these collisions using the R-matrix method. Here this method is tested for the atom -- atom collisions described by a Morse potential. Analytic solutions for continuum states of the Morse potential are derived and compared with numerical results computed using an R-matrix method where the inner region wavefunctions are obtained using a standard nuclear motion algorithm. Results are given for eigenphases and scattering lengths. Excellent agreement is obtained in all cases. Progress in developing a general procedure for treating ultra-low energy reactive and non-reactive collisions is discussed.Comment: 18 pages, 6 figures, 3 tables, conferenc

Digital heritage politics from the perspective of relational sociology: the case of Nüshu culture in China

In proposing a new conceptual framework that systematises and comprehends the complex dynamics of cultural heritage politics in China, the study takes its inspiration from Chinese scholars who have explored the relevance of Guanxi beyond its immediate business context. While current discourse theory acknowledges that heritage-making entails complex relationships that structure this making, there is as yet no systematic theoretical account of how these relationships co-exist, mediate and transform heritage-making. In developing a relational sociological framework based on the work of John Dewey, the analysis of digital heritage-making includes a case study of Nüshu, the dominant language and culture in villages on the southwestern frontier of China’s Hunan Province. Using netnography, the study analyses a range of online accounts and websites that form part of the heritage-making process. Drawing on rich digital material that includes online competitions, virtual conversations or comments and digital certificates, the findings highlight the need for a more dynamic relational perspective that acknowledges the mutuality of heritage producers and the process of heritage-making. The findings contribute to a sociological account of heritage-making in China and to a more generalist theory of relational sociology

A Method Based on a Nonlinear Generalized Heisenberg Algebra to Study the Molecular Vibrational Spectrum

We propose a method, based on a Generalized Heisenberg Algebra (GHA), to reproduce the anharmonic spectrum of diatomic molecules. The theoretical spectrum generated by GHA allows us to fit the experimental data and to obtain the dissociation energy for the carbon monoxide molecule. Our outcomes are more accurate than the standard models used to study molecular vibrations, namely the Morse and the $q$-oscillator models and comparable to the perturbed Morse model proposed by Huffaker \cite{hf}, for the first experimental levels. The dissociation energy obtained here is more accurate than all previous models

Toxicity of lunar dust

The formation, composition and physical properties of lunar dust are incompletely characterised with regard to human health. While the physical and chemical determinants of dust toxicity for materials such as asbestos, quartz, volcanic ashes and urban particulate matter have been the focus of substantial research efforts, lunar dust properties, and therefore lunar dust toxicity may differ substantially. In this contribution, past and ongoing work on dust toxicity is reviewed, and major knowledge gaps that prevent an accurate assessment of lunar dust toxicity are identified. Finally, a range of studies using ground-based, low-gravity, and in situ measurements is recommended to address the identified knowledge gaps. Because none of the curated lunar samples exist in a pristine state that preserves the surface reactive chemical aspects thought to be present on the lunar surface, studies using this material carry with them considerable uncertainty in terms of fidelity. As a consequence, in situ data on lunar dust properties will be required to provide ground truth for ground-based studies quantifying the toxicity of dust exposure and the associated health risks during future manned lunar missions.Comment: 62 pages, 9 figures, 2 tables, accepted for publication in Planetary and Space Scienc

Temperature dependence of hot luminescence in solid xenon: theory and experiment

Vibrational relaxation of self-trapped excitons in solid xenon has been investigated both experimentally and theoretically. Hot luminescence spectra of the crystal have been measured in a wide temperature range (from liquid helium temperature to 100 K), using x-ray and two-photon excimer laser (ArF and KrF) excitation. The theoretical analysis is based on a recent nonperturbative relaxation theory and on a rigorous quantum mechanical Franck—Condon approach

A quasi-bound rovibrational state of hydrogen molecule resulting from hyperfine proton-electron spin-spin interaction

A potential energy surface for the ground-state hydrogen molecule is constructed, which includes nonadiabatic, relativistic, radiative and hyperfine corrections. A new interpretation is given to the “exotic” level E14, 4, very close to the molecule's dissociation limit. Hyperfine proton-electron spin-spin interaction not only splits the atomic ground state but it also changes the long-range part of the related potential. As a result, the level E14, 4 is converted into an extremely narrow resonance with lifetime of over 5 minutes
