Changes in Education under the Influence of Digital Technologies: main Problems and Risk of Division

Digital technologies are rapidly changing the process of education. Online courses have become a common tool of gaining knowledge outside the university. Multimedia education, penetrating traditional educational institutions (schools, colleges, and universities), changes the structure of education and brings new elements to the communications during the educational process. This article considers one level of change in the model of education. On the one hand, there are advantages associated with the democratization of education. At the time of their foundation, universities were the creators of new elites – scientific and educational meanwhile, in the twenty-first century, the process of democratization and the accessibility of university education has been linked to the digitalization. On the other hand, territorial and other restrictions have been lifted. And this is a very controversial process that poses many challenges for students, one of the most noticeable of which is the lack of real contact with the teacher and the transformation of the educational process into an ”educational conveyor belt.” At the same time, personal contact with the teacher is becoming more expensive. The authors have collected studies that examine the dynamics of this emerging stratification of education. Based on the work of the pioneers in the study of digital education, the authors develop their ideas, focusing on the formation of the modern models of education, defined as affordable electronic and elite traditional. Keywords: online courses, online education, MOO

Determination of Upconversion Quantum Yields Using Charge-Transfer State Fluorescence of Heavy-Atom-Free Sensitizer as a Self-Reference

The efficiency of photon upconversion via triplet–triplet annihilation is characterized by an upconversion quantum yield (ΦUC); however, uncertainties remain for its determination. Here, we present a new approach for the relative measurement of ΦUC for green-to-blue upconversion using BODIPY–pyrene donor–acceptor dyad (BD1) as a heavy-atom-free triplet sensitizer. This new approach exploits broad fluorescence from a charge-transfer (CT) state of BD1, which possesses (i) a significant Stokes shift of 181 nm in dichloromethane and (ii) a comparably high CT-fluorescence quantum yield (Φref = 7.0 ± 0.2%), which is independent from oxygen presence and emitter (perylene) concentration while also exhibiting a linear intensity dependence. On the basis of this, we developed an upconversion reference using the BD1 sensitizer mixed with perylene (1 × 10–5 M/1 × 10–4 M) in dichloromethane. With this reference system, we investigated the performance of three BODIPY donor–acceptor dyads in the upconversion process and achieved one of the highest ΦUC of 6.9 ± 0.2% observed for heavy-atom-free sensitizers to date

Modelando las operaciones de una empresa basadas en la ideología marginal

El artículo explora el tema de actualidad del modelado de operaciones empresariales con el uso del análisis marginal. La economía de mercado se caracteriza por la mayor inestabilidad del complejo sistema socioeconómico, que es casi imposible de comprender y estudiar por completo. Las empresas se enfrentan a una intensa competencia. Una adecuada toma de decisiones de gestión requiere evaluaciones exhaustivas en profundidad de la situación ypronósticos fiables. Una empresa que hace pronósticos correctos obtiene ganancias adicionales en comparación con una que se abstiene de pronosticar. Mientras tanto, una empresa que hace un pronóstico incorrecto es la que más pierde. Las decisiones gerenciales a menudo se basan en un análisis de equilibrio, i. e., análisis marginal. Este documento explora ejemplos en los que, incluso en los casos en que se toman decisiones desventajosas (como se muestra en el análisis de equilibrio), el entorno puede conducir a resultados positivos, i. e., al menos una ganancia moderada, a través de la validación de la decisión gerencial mediante análisis y cálculos adicionales. Se utilizaron los métodos de indagación, análisis retrospectivo y documental, así como síntesis, generalización y sistematizació

Modelando las operaciones de una empresa basadas en la ideología marginal

The paper explores the topical subject of modeling enterprise operations with the use of marginal analysis. The market economy is characterised by the heightened instability of the complex socioeconomic system, which is almost impossible to fully grasp and study. Businesses face intense competition. Adequate managerial decision-making requires in-depth comprehensive assessments of the situation and reliable forecasting. A firm that makes correct forecasts gains additional profit compared to one abstaining from forecasting. Meanwhile, a firm making an incorrect forecast loses most of all. Managerial decisions often rely on break-even analysis, i. e., marginal analysis. This paper explores examples where even in cases when disadvantageous choices are made (as shown by break-even analysis), the setting can still lead to positive results, i. e., at least a moderate profit, through the validation of the managerial decision by further analysis and calculations. The methods of enquiry, retrospective and document analysis, as well as synthesis, generalisation and systematisation were used.El artículo explora el tema de actualidad del modelado de operaciones empresariales con el uso del análisis marginal.

Especificidades regionais do desenvolvimento inovador de sistemas socioeconômicos na Federação Russa

The Russian economy has a tendency to slow down and reduce real investment, which hinders the possibility of innovative development. This is largely a consequence of the situation in the credit sector, especially in terms of the practical inaccessibility of Bank lending to small and medium-sized businesses. The objectives of the work are to justify an effective mechanism for increasing the availability of credit resources for small and medium-sized businesses, directly focused on innovation. Overcoming the contradiction between the banks aspiration to commercial profit and ignoring the objective needs of national expanded reproduction, and expanding the availability of Bank lending for the participants of the innovation process at the present stage of Russian development are associated with the effective interaction of the SME Corporation and the banking system in the process of production cooperation. The results of the study can be used to develop new organizational, economic and management mechanisms and tools for financing innovation.La economía rusa tiene una tendencia a desacelerar y reducir la inversión real, lo que dificulta la posibilidad de un desarrollo innovador.
