Russian Freshmen Future Profession Choice in the Conditions of Digitalization: New Challenges of Labour Markets

The prestige and values of higher education are traditionally high in Russia and overseas countries. For several generations, there has been a youth orientation towards higher education. Higher education and diplomas are perceived by a person primarily as a means of social mobility. Profession sets a certain “social background” for people’s life. At the same time, however, over the past few decades the assessment of the prestige associated with certain professions and specialties has dramatically changed and the labor market has changed, too. The the desire for higher education among young people continues to grow in Russia. Today’s students, future specialists, face new challenges of the labor market: firstly, availability of desired and demanded professions acquisition on the labor market; secondly, disappearance of old and the emergence of new professions; thirdly, digitalization of the labor market; fourthly, the formation of specialist competencies that are in demand both on the local and global labor markets. The major research objectives were to study the issues of students’ profession choice and their opinion on the demanded / non-demanded professions on modern labor market. The research methodology combines both quantitative and qualitative approaches. The primary data was collected using questionnaires and indepth-interviews. 250 freshmen of the Ural Federal University and 250 freshmen of Saint-Petersburg State University were questioned on the basis of quota sampling. In depth-interviews (15) were organized for the educators engaged in the system of higher education. The study has revealed the issue of inequality in access to higher education as well as of inequality in access to getting prestigious and demanded professions on labor market.The majority of the respondents look for occupation suited to abilities and to their own interests. For young people the main thing is that the profession should not only make profit, but also a career progress and give new professional knowledge. The research has fixed that the majority of the students believe that they have made the right choice of specialty and they are well aware of how their future professional activity will be. About 30.0% of young people do not often choose those professions that they would like to be trained at the university, but those that are possible due to their “accessibility”. The students’ professional choice does not correspond to their ideas about their future profession and their psychological characteristics.

Correlation versus randomization of jerky flow in an AlMgScZr alloy using acoustic emission

International audienceJerky flow in solids results from collective dynamics of dislocations which gives rise to serrated deformation curves and a complex evolution of the strain heterogeneity. A rich example of this phenomenon is the Portevin-Le Chatelier effect in alloys. The corresponding spatiotemporal patterns showed some universal features which provided a basis for a well-known phenomenological classification. Recent studies revealed peculiar features in both the stress serration sequences and the kinematics of deformation bands in Al-based alloys containing fine microstructure elements, such as nanosize precipitates and/or submicron grains. In the present work, jerky flow of an AlMgScZr alloy is studied using statistical analysis of stress serrations and the accompanying acoustic emission. As in the case of coarse-grained binary AlMg alloys, the amplitude distributions of acoustic events obey a power-law scaling which is usually considered as evidence of avalanchelike dynamics. However, the scaling exponents display specific dependences on the strain and strain rate for the investigated materials. The observed effects bear evidence to a competition between the phenomena of synchronization and randomization of dislocation avalanches, which may shed light on the mechanisms leading to a high variety of jerky flow patterns observed in applied alloys

Synthesis and systematic optical investigation of selective area droplet epitaxy of InAs/InP quantum dots assisted by block copolymer lithography

We report on the systematic investigation of the optical properties of a selectively grown quantum dot gain material assisted by block-copolymer lithography for potential applications in active optical devices operating in the wavelength range around 1.55 um and above. We investigated a new type of diblock copolymer PS-b-PDMS (polystyrene-block-polydimethylsiloxane) for the fabrication of silicon oxycarbide hard mask for selective area epitaxy of InAs/InP quantum dots. An array of InAs/InP quantum dots was selectively grown via droplet epitaxy. Our detailed investigation of the quantum dot carrier dynamics in the 10-300 K temperature range indicates the presence of a density of states located within the InP bandgap in the vicinity of quantum dots. Those defects have a substantial impact on the optical properties of quantum dots.Comment: 11 pages, 5 figures, 1 tabl

Unusual behavior of the Portevin - Le Chatelier effect in an AlMg alloy containing precipitates

Stress serration patterns and kinematics of deformation bands associated with the Portevin - Le Chatelier effect in an Al-Mg alloy were investigated by analyzing the evolution of the applied stress and axial strain distribution. In contrast to usually observed strain localization behaviors, referring to propagating and static deformation bands at high and low strain rates, respectively, the propagation mode was found to persist in a wide strain-rate rang

Scaling and complexity of stress fluctuations associated with smooth and jerky flow in a FeCoNiTiAl high-entropy alloy

Recent observations of jerky flow in high-entropy alloys (HEA) revealed a high role of self-organization of dislocations in their plasticity. The present work reports first results of investigation of stress fluctuations during plastic deformation of a FeCoNiTiAl alloy, examined in a wide temperature range covering both smooth and jerky flow. These fluctuations, which accompany the overall deformation behavior representing an essentially slower stress evolution controlled by the work hardening, were processed using complementary approaches comprising the Fourier spectral analysis, the refined composite multiscale entropy, and multifractal formalisms. The joint analysis at distinct scales testified that even a macroscopically smooth plastic flow is accompanied with nonrandom fluctuations, disclosing self-organized dynamics of dislocations. Qualitative changes in such a fine-scale "noise" were found with varying temperature. The observed diversity is significant for understanding the relationships between different scales of plasticity of HEAs and crystal materials in general.Comment: 13 pages main body, 6 figures, 2 appendices, 65 citations (22 pages overall

Interrelation between the Portevin Le-Chatelier effect and necking in AlMg alloys

Plastic flow instability caused by the Portevin Le-Chatelier (PLC) effect and its influence on the necking instability were studied in a binary and a precipitation-strengthened AlMg alloy using the digital image correlation (DIC) technique. Coarse-grained structure and two different finegrained states distinctly distinguished by dislocation density were produced in both alloys using similar routes of thermomechanical processin

Dislocation transport and intermittency in the plasticity of crystalline solids

International audienceWhen envisioned at the relevant length scale, plasticity of crystalline solids consists in the transport of dislocations through the lattice. In this paper, transport of dislocations is evidenced by experimental data gathered from high-resolution extensometry carried out on copper single crystals in tension. Spatiotemporal kinematic fields display spatial correlation through characteristic lines intermittently covered by plastic activity. Intermittency shows temporal correlation and power-law distribution of avalanche size. Interpretation of this phenomenon is proposed within the framework of a field dislocation theory attacking the combined problem of dislocation transport and long-range internal stress field development. Intermittency and transport properties show remarkable independence from sample size, aspect ratio, loading rate, and strain-rate sensitivity of the flow stress
