The journal’s key topics for 2017 involve the role of tradition and innovations in folklore genres and the interconnection between folklore and folk mythology as well as between folklore texts and oral history. Additionally, Issues 3 and 4 feature sections to commemorate the 870th anniversary of the founding of Moscow and the centenary of the Russian October Revolution

Ultrasound in the Intensification of the Concentration of Lead and Cadmium on Sorbents

Показано, що використання одночасної дії ультразвуку високої та низької частот дає змогу покращити стабільність суспензії та метрологічні характеристики отриманих результатів. Розроблено безпечну (без використання токсичних розчинників) методику електротермічного атомно-абсорбційного визначення свинцю і кадмію із чутливістю визначення 0,05 і 0,001 мг/кг відповідно. It is shown that the use of the simultaneous action of ultrasonic high-frequency and low Koi can improve the stability of the suspension and improve the metrological characteristics of the results. Designed without-Pasni (without the use of toxic solvents) method in electro-cal atomic-absorption determination of lead and cadmium sensitivity of the determination of 0.05 and 0.001 mg / kg, respectively.Роботу виконано на кафедрі охорони праці та інженерної педагогіки УІП

Історична ретроспектива розвитку сільськогосподарського дорадництва в Україні (1995–2015 рр.)

Реформи в сільському господарстві незалежної України породили велику кількість нових приватних власників і користувачів земельних угідь. Значна частина з них – фермери, власники особистих селянських господарств – мають недостатній рівень сільськогосподарських знань, зокрема щодо використання новітніх технологій у рослинництві та тваринництві. Тому вони потребують професійної допомоги, консультування і підвищення рівня сільськогосподарських знань. Такі послуги є елементами сільськогосподарського дорадництва, як окремого виду діяльності в сільському господарстві. Автором проаналізовані етапи становлення та розвитку сільськогосподарської дорадчої діяльності в Україні та запропоновані напрями її удосконалення

Managing the motivation provision of universities in the context of the educational process digitalisation

The paper proposes a method for increasing the motivation of university teachers to work with digital technologies on the example of teaching foreign languages. The fear of complete displacement of the teacher by digital technologies leads to many ethical and psychological problems, resulting in a reluctance to use training programmes in the educational process. To increase the motivation of teachers to work in the digital environment, it is proposed to involve them in the use of digital educational technologies to adapt the work plans of disciplines to the preparation level of students entering universities. The specialists team composition required for the implementation of this method in practice has been formed. Additional factors for increasing the teachers motivation to work in a digital environment when working in a team have been shown. The proposed approach can be used in the implementation in digital educational systems of educational institutions

Transformation of enterprise management systems in the context of digitalization

The article deals with the issues of qualitative transformation of enterprise management systems in the digital economy, the impact of the introduction of digital intelligence in the market space on the improvement of technologies for building business processes. The relevance of the problem under consideration is due to the huge competition in the existing business space, as well as the need to improve the efficiency of enterprises in the conditions of digitalization, adaptation of their business models to the new digital environment. The purpose of the study is to develop a methodology for the transformation of enterprise management systems that would improve the efficiency of all business processes in practice. The objectives of the study include the following: finding tools for determining the level of digital intelligence of Russian enterprises; establishing dependencies of profitability of enterprises on the level of digitalization of the latter; determining the nature and ways of transformation of management systems in the conditions of digitalization. Sociological and empirical research methods are widely used in the work. The main results of the study can be considered the introduction of an integral indicator of the level of digital intelligence of business systems; the formation of an enterprise business model in the context of digitalization; the derivation of the dependence of the integral indicator of the level of digital intelligence and profitability of enterprises; the establishment of a correlation between the growth of gross income of large enterprises in Russia and its GDP

Metal-insulator transition induced by 16O -18O oxygen isotope exchange in colossal negative magnetoresistance manganites

The effect of 16O-18O isotope exchange on the electric resistivity was studied for (La(1-y)Pr(y))0.7Ca0.3MnO3 ceramic samples. Depending on y, this mixed perovskite exhibited different types of low-temperature behavior ranging from ferromagnetic metal (FM) to charge ordered (CO) antiferromagnetic insulator. It was found that at y=0.75, the substitution of 16O by 18O results in the reversible transition from a FM to a CO insulator at zero magnetic field. The applied magnetic field (H >= 2 T) transformed the sample with 18O again to the metallic state and caused the increase in the FM transition temperature Tc of the 16O sample. As a result, the isotope shift of Tc at H = 2 T was as high as 63 K. Such unique sensitivity of the system to oxygen isotope exchange, giving rise even to the metal-insulator transition, is discussed in terms of the isotope dependence of the effective electron bandwidth which shifts the balance between the CO and FM phases.Comment: 5 pages (RevTeX), 2 eps figures included, to appear in J.

TRUST AS A VIRTUAL TEAM EFFECTIVENESS FACTOR

A relatively new phenomenon in management practice – a virtual team has been considered. Based on a study of a wide range of domestic and foreign sources, it has been shown, what problems arise during the formation and operation of virtual teams. Attention on the problem of mutual trust in the team has been focused. It has been concluded that the lack of common social norms and opportunities for mutual control, the lack of direct personal contacts, cross-cultural problems, and the lack of informal communication impede confidence building. However, the rapid idealization of a communication partner, the ability to create the effect of physical presence with minimal means can contribute to building trust and team spirit. The article is addressed to specialists in the field of personnel management and all interested in modern technologies of labor management

Low molecular weight thymic factor inhibits histamine release from basophils

Low molecular weight thymic factor stimulates the suppressor function of T-lymphocytes, increases cAMP content (but not cGMP) in lymphocytes and inhibits histamine release from sensitized basophils. The mechanisms of LTF action are discussed
