Transformation of Managerial Competencies within the Context of Global Challenges

Abstract: This contribution presents an analysis of the transformational changes in the global environment on the content of modern models of managerial competencies. Theoretical approaches to the definition of managerial competencies according to international standards are studied, and on this basis a hierarchy of competencies, within the context of their acquisition through professional training, is determined. The predictions and changes in the basic competencies of managers in the near future (2025) are analysed. Sets of general managerial (organizational) competencies (hard skills) and non-specialized supra-professional competencies (soft skills) are defined and compared. Digital competences and intercultural competences are defined as conceptually new skills required by a modern effective manager.

Ukrainian women in the new economy

Abstract: EnglishUkraine has been independent since 1991. This study explored through a qualitative methodology how Ukrainian women perceived their lives had changed in the 1990s. It was found that women believed their families were barely able to subsist. They also believed that their lives were better under Soviet rule.FrenchL’Ukraine a gagne son independance depuis 1991. Cette etude exploratoire menee avec une methodologie qualitative, a explore comment les femmes ukrainiennes perµoivent leurs changements de vie au cours de la decennie. On constate que les femmes croient que leurs familles subsistent a peine de 1990. Elles croient egalement que leurs vies etaient meilleures durant les annees du regime sovietique.SpanishUcrania es independiente desde 1991. Este estudio exploro, a traves de la metodologia cualitativa, como perciben las mujeres ucranianas que sus vidas han cambiado en la ultima decada.

Vitamin D status in adults and children in Transcarpathia, Ukraine in 2019

Abstract: Vitamin D deficiency is a global health problem, it is assessed by measuring serum 25-hydroxivitamin D (25(OH) D), nevertheless epidemiological data for many countries remains underreported. To study the prevalence of vitamin D deficiency throughout the calendar year in a large cohort recruited ina multiethnic Transcarpathian region of Ukraine. In this retrospective study 25(OH) D serum concentration was measured during all 12 months of the year 2019 by electrochemoluminescent assay on the automatic analyzer Cobas e411 in 1823 subjects, including both children and adults (1551 females (85.03%) and 273 males (14.97%)). The mean 25(OH) D concentration in adults demonstrates significantly lower levels compared to children (22.67 ± 8.63 ng/ml vs. 26.00 ± 10.72 ng/ml respectively, p < 0.001). Adult women expressed significantly lower mean annual serum 25 (OH) D concentrations in comparison to men (22.29 ± 8.46 ng/ml vs. 25.75 ± 9.38 ng/ml respectively, p < 0.001). In contrast, children did not show a significant difference between sexes (girls 24.98 ± 10.38 ng/ml vs. boys 27.01 ± 11.01 ng/ml, p = 0.2003). In the winter months, 25(OH) D levels fell below 20 ng/ml in 51,74% of adult population of Thranscarpathia, and in 12.91%, − below 12 ng/ml. The results of this study contradict the previously reported evaluations of the vitamin D levels in Ukraine which were assessed by measuring serum 25(OH) D. Specifically, only approximately half of the studied population is vitamin D deficient during winter season. This study features the most representative sample size in Ukraine to date.

In situ investigations of laser and thermally modified As2S3 nanolayers: Synchrotron radiation photoelectron spectroscopy and density functional theory calculations

Abstract: As-deposited, annealed, and in situ As2S3 nanolayers, illuminated by blue (405 nm) and red (650 nm) laser light, were studied using synchrotron radiation photoelectron spectroscopy and DFT electronic structure calculations. Changes in composition and local atomic coordination occurring in the irradiated region of As2S3 films were monitored by analysis of As 3d and S 2p core levels. These studies show that both the thermal treatment and the red laser illumination of As2S3 nanolayers decrease the concentration of homopolar (As-As and S-S) bonds. From the other hand, an increasing concentration of As-rich structural units (s.u.) with a homopolar As-As bond was observed under in situ blue laser illumination of As2S3 nanolayers. Molecular orbital energies were calculated for different As- and S-centered s.u. and used for the interpretation of the core levels and valence band spectra. The surface local structure of the As2S3 nanolayers and its photoinduced transformation are discussed in detail.
