Authors: Амосов Павел Николаевич , Брагин Альберт Владимирович , Старопопов Геннадий Андреевич , Волкова Анастасия Андреевна , Афонов Кирилл Игоревич
Published: November 2020

Исследования, проведенные на лугах северо-востока Архангельской области в долине реки Пинеги, показали изменения фауны и численности некоторых видов птиц, связанные со значительным сокращением или прекращением сельскохозяйственного использования лугов. Следствием стало сокращение численности или отсутствие полевого жаворонка Alauda arvensis и чибиса Vanellus vanellus на некоторых лугах, ранее используемых как выпасы или сенокосы. Исчезновение дубровника Ocyris aureola не связано с прекращением сельскохозяйственного использования лугов. В то же время, в связи с зарастанием лугов древесно-кустарниковой растительностью, относительно высока численность лугового чекана Saxicola rubetra, камышовой овсянки Schoeniclus schoeniclus, пеночки-веснички Phylloscopus trochilus, чечевицы Carpodacus erythrinus, фифи Tringa glareola, большого улита Tringa nebularia и др.

Studies conducted in the meadows of the northeast of the Arkhangelsk Region in the valley of the Pinega River, showed changes in the fauna and abundance of some bird species associated with a significant reduction or cessation of the agricultural use of the meadows. The effect was a reduction in the number or absence of the Skylark Alauda arvensis and the Lapwing Vanellus vanellus in some meadows previously used as pastures or hayfields. At the same time, due to the overgrowing of meadows with tree-shrub vegetation, the numbers of Whinchat Saxicola rubetra, Reed Bunting Schoeniclus schoeniclus, Willow Warbler Phylloscopus trochilus, Common Rosefinch Carpodacus erythrinus, Wood Sandpiper Tringa glareola, and Greenshank Tringa nebularia became relatively high. The disappearance of Yellow-breasted Bunting Ocyris aureola is not related to the termination of the agricultural use of the meadows.

The Public Policy to Support High Growth Firms: Is a New Ideology of Industrial Policy Born?
Authors: Polunin Yu. A. , Yudanov A. Yu.
Published: November 2020

The article discusses a new branch of industrial policy — support of high growth firms (HGFs, gazelle firms). Methodologically, the article is the first in Russia analysis of the international literature on the state programs of stimulation of the HGFs. The period, starting with the first publications on this topic in 2005–10 and ending with modern editions, has been covered. The primary purpose of the article was the establishment of the place of the policy of support for the HGFs within the framework of industrial policy, as well as to establish the changes that this new type of policy makes to economic regulation in general. Significant differences between the policy of support for HGFs and public policy on small and medium-sized enterprises, as well as differences from innovation policy, have been revealed. We proved that in the stimulation of the HGFs is particularly acute the generic and, at the same time, the most controversial feature of industrial policy — its selectivity, i.e. targeting specific economic actors, rather than the whole economy.

Platform Employment — the Scale and Evidence of Instability
Authors: Bobkov V. N. , Chernykh E. A.
Published: November 2020

The relevance of the study of platform employment is determined by the fact that under the influence of digitalization, demographic and other challenges over the past decade, its scale has radically increased in the world. The emergence of digital labour platforms has become one of the important tools of the new organization and structuring of the labour market. The article reveals the scale of platform employment, statistically confirmed signs of its instability, as well as its positive and negative effects on workers, employers, and the economy as a whole. Measures are proposed to enhance its positive and prevent negative effects. The subject of the article is the socio-economic aspects of employment through online platforms. Platforms are digital (virtual) technological devices-software, algorithms, control systems using artificial intelligence and other digital means of labour. These new tools allow legal entities and/or individuals to join the unlimited and unknown circle of other individuals or legal entities (so-called crowd workers) for the production of goods and the provision of specialized services on a paid basis. The purpose of the article is to study the extent of the spread of platform employment, the mechanisms of its economic power over customers, to identify the benefits and risks of platform employment, as well as tools for using the former and limiting the latter. We used general scientific methods (system analysis, comparison, description, generalization, systematization, formalization), special methods (source analysis, SWOT analysis, expert assessment method, statistical methods), institutional approach and other methods of scientific research.
Circular Economy and its Indicators for Russia
Authors: Bobylev S. N. , Solovyeva S. V.
Published: November 2020

In the world, the theory of the circular economy and its formation in the real economic system is rapidly developing. Many international organizations (OECD, EU) and countries already have their programs for developing such an economy. The article emphasizes that the practical implementation of the concept of “best available technologies” is vital for the transformation of the current linear model of the economy in many countries, including Russia. In Russia, there are many obstacles to the formation of a circular economy; the inertia of the existing export-raw material model is excellent, which is unsustainable and linear. A dangerous trend is the growth of waste intensity at the macro level. The article analyzes and adapts for Russia the UN Sustainable Development Goals directly related to the circular economy, proposes and quantifies key indicators. In the field of quantitative indicators, four areas have been identified for the development of crucial indicators set for the circular economy in Russia. An author’s formula for structuring the consumption of natural resources taking into account technological efficiency and waste is proposed. The importance of using the proposed toolkit of natural-product verticals combining primary natural resources / raw materials with final consumption and allowing us to estimate the size of the lost primary natural resources is emphasized. The indicators of waste management, in combination with production and consumption systems, are analyzed. For a circular economy, it is fundamentally important to calculate the resource and material intensity indicators of various sectors and their weight in the gross product, which will allow to assess the impact of potential structural changes on waste generation and conduct a comparative analysis with the corresponding indicators of other countries.
The Level of Well-being of the Working Population as a Concentrated Expression of the Quality of Working Life
Authors: Menshikova O. I.
Published: November 2020

The purpose of the article is to substantiate the need and the possibility of improving the quality of working life in Russia as one of the main factors in the growth of the well-being of the working population. The author examined the influence of the conditions of employment of the workforce in the process of its reproduction and proved that the wage index (among all components of the quality of working life) has particular importance. The author also presented the tools of expert assessment of the quality of working life from the point of view of the achieved level of wages. Using these tools the author compiled a generalised characteristic of the current state of the quality of working life in Russia according to four criteria in terms of the achieved level of wages necessary to perform the reproductive function. Comparative analysis of the dynamics of nominal and real wages in the Russian economy for the years 2000–2018 showed a significant, long-term lag between growth of real and nominal wages. Further, the author showed the profile of Russian poverty concerning the main components of the quality of working life and presented the social and economic consequences of not decreasing poverty. Finally, the author constructs a set of socio-economic indicators of the standard of living of the working population due to the low level of satisfaction of the needs of workers and their families in nutrition, education, health, related to the deficit of family budgets. It makes possible to choose the main directions of the formation and implementation of the state and corporate social policy to overcome the negative trends in the level and quality of life of the working population associated with low quality of working life.
Analysis of Global Economic and Political Factors and Challenges of the Eurasian Economic Integration
Authors: Zubenko V. A. , Masalimova A. M.
Published: November 2020

The development of the EAEU takes place in the context of the formation of a new system of world economic relations and the transformation of the rules of world trade. Further areas of multilateral cooperation between states and regional integration associations are emerging (including the digital economy, cryptocurrencies). As a consequence of the aggressive foreign policy of economically developed countries, the regionalization of trade and economic ties is gaining popularity, which makes it urgent to reformat trade relations with regional integration associations. Along with this, the primary integration effect associated with the opening of national markets and the simplification of trade rules, which manifested itself at the first stages of the formation of the customs union and the single economic space (CES), is being exhausted. The volumes of mutual trade of the member states are changing, but its share in the capacity of the common market of the EAEU remains virtually unchanged from year to year. The further growth of trade and economic ties within the EAEU is mainly due to the removal of existing obstacles and the qualitative improvement of the conditions for doing cross-border business. Various negative phenomena distort the integration agenda and substantially neutralize the positive effects of integration. The reasons noted above make the task of a comprehensive study of the economic and geopolitical factors of the integration of member states and new challenges to the integration processes urgent. To develop approaches to strategic planning for the development of the EAEU, adequate assessments of the use of the integration potential of the member states should be made and areas with the most significant reserves for building up integration cooperation should be identified. The full involvement of Armenia and Kyrgyzstan in the orbit of the Eurasian economic integration, as well as severe changes in the external economic situation that have occurred in recent years, require the actualization of possible scenarios for the development of the Eurasian Economic Union and the development of new tactics for the response of the EAEU and the Union member states to newly emerging factors and challenges affecting on integration processes.

Authors: Donetskova O. Yu. , Petrushova V. V.
Published: November 2020

The mobilisation of resources determines the investment activity of banks for investment purposes. It is an important direction of development of the country’s economy, which emphasises the relevance of the study. The purpose of the article is to determine the investment potential of banks and their investment targets. The current state of the investment portfolio of banks was assessed using quantitative, comparative, structural and factor methods. The logic of the study allowed us to evaluate the activity of banks in the securities market and identify the acute problem of market capture by large banks. As a result, competition with other banks does not develop and the monopoly of Moscow banks increases. The authors analysed the quality of the bank’s investment portfolio by evaluating the volume and structure of attracted resources and identifying their risk level. A systematic and comprehensive approach to the analysis of investment activities of banks allowed the authors to make several recommendations for its improvement, which determines the scientific and practical significance of the study

Authors: Strizhkova L. A. , Kuranov G. O.
Published: November 2020

The article is devoted to the development of indicators of the quality of economic growth. The authors associate the primary practical purpose of the system of indicators of the quality of economic growth with improving information and scientific and methodological support for the process of developing and implementing decisions of the state’s economic policy. We considered methodological aspects of compiling a system of indicators of the quality of economic growth, described problems in this area, and proposed approaches to their solution. Further, we gave estimates of factors that determine the dynamics of economic growth. We have provided a special place to the discussion of controversial issues in the field of assessing the quality of economic growth, including the problem of reconciling the idea of inclusive development and endogenous growth model of the Russian economy. It also includes approaches to the innovative factor in development outcomes that reflect the regional dimension in the system of quality indicators of economic development. The authors present and justify their views on several controversial issues, continuing the discussion of this topic that began in the framework of the Efimov Readings II (2019).

В кристаллах обеих модификаций реализуется идентичная геометрия молекулы ключевого соединения, а кристаллы (несмотря на разные их сингонии и параметры элементарных ячеек) характеризуются формированием в них идентичного одномерного супрамолекулярного мотива за счет реализации классических водородных связей N—H…O типа и нековалентных взаимодействий более слабого порядка — С—H…S в кристалле 1a и C—H…N в кристалле 1b. В кристаллах наблюдается тетрагональная взаимная упаковка одномерных мотивов, ориентированных вдоль наименьшего параметра элементарной ячейки в обоих случаях. Сольватные молекулы в кристалле 1b локализованы в нольмерных полостях. Несмотря на более плотную упаковку молекул в кристаллосольвате 1b, его поликристаллический образец подвержен твердофазным изменениям и, как установлено методом порошковой дифракции, с течением времени частично переходит в бессольватную форму 1а, характеризующуюся менее плотной упаковкой молекул в кристалле.
The narrative of translocation as a way to construe the protagonist's horizon of consciousness (The novel “Boarding House” by S. Zhadan)
Authors: Meizerska Tetiana
Published: November 2020

The topicality and novelty of the proposed article is accounted for by the need to involve into the space of Ukrainian literary studies those methodologies that are extremely rarely used due to various circumstances and that remain on the margins of scientific interests, though having powerful potential opportunities to address new approaches to studying poetics and interpretation of artistic texts. The subject of the research in the proposed article is the moving semantic horizon of protagonist’s consciousness in S. Zhadan’s novel “Boarding School”, which expresses the potential possibilities of construing his identity. Using the methods of phenomenological and existential analysis of the structures of the living world and shifts in the horizons of consciousness developed by E. Husserl and A. Bergson, the author of the article proves that they 1) are naturally in line with the specificity of the writer’s artistic thinking aimed at the analysis of the characters in their search of the purpose of existence and 2) this search of explication of the inner world and shifts of consciousness of the protagonist Pasha is carried out within the narrative of shifting horizons of “protoimpression” which, according to Husserl, in each case is the interaction of three integral components manifested in the experience of “now”, which inevitably fits into the horizon of “once” (retentional — past-related) and “then” (protential — future-related) modifications. It is proved that the artistic narrative of the novel is designed to capture the thickening of the horizons of consciousness and memory of the protagonist, whose experience appears in different modes: perception / rejection, imagination, dream, memory, various visualization techniques, etc. Emphasis is placed on the methods of transferring “shifts” of the protagonist’s consciousness related to the film narrative, the process of image-experience, where profound expansion of memory gains special importance, the formation of subjective impressions: associative saturation of details, attraction to cinematic visualisation, change focalization, “subjective camera effect”, the use of frame switching techniques, etc. Prospects for further studies are associated with the further involvement of the methodology of phenomenological and existential analysis and knowledge of the application of film narration techniques for the analysis of the plot and composition skills of the writer.

La aplicación de agroquímicos en la floricultura, disminuye gradualmente la fertilidad y poblaciones de microorganismos benéf icos del suelo, siendo los actinomicetos indicadores biológicos de la calidad edáf ica. En el presente artículo se propuso como objetivo comparar los cambios en la densidad poblacional de actinomicetos en suelos florícolas de rosa, clavel y agapando, y su tratamiento con vermicomposta. Los tratamientos fueron agapando como control, suelo con plaguicida del cultivo de rosa, suelo con plaguicida del cultivo de clavel, suelo con plaguicida del cultivo de rosa adicionado con vermicomposta a 40 Mg ha-1 y suelo con plaguicida del cultivo de clavel adicionado con vermicomposta a 40 Mg ha-1. Durante 28 días, se cuantif icó la densidad de población de actinomicetos totales, por el método de conteo en placa. Los suelos florícolas son de textura franco-arenosa, por su bajo contenido en materia orgánica, se adicionó vermicomposta a los tratamientos. La población de actinomicetos totales de los suelos florícolas y vermicomposta fue del orden de 1 × 105 UFC g-1 de suelo, lo que indicó un bajo contenido. Se detectaron cambios en la densidad poblacional de actinomicetos en los tratamientos de suelos florícolas de rosa y clavel con y sin vermicomposta, siendo mayor en los suelos florícolas de rosa y clavel sin la adición de vermicomposta. Los cambios en la población de actinomicetos de los suelos cultivados con rosa y clavel indican que estos microorganismos están adaptados a la aplicación de plaguicidas. La adición de vermicomposta mejoró las propiedades f isicoquímicas de los suelos florícolas en sus respectivos tratamientos.

La vermicomposta es un abono que mejora la fertilidad del suelo y la productividad de los cultivos; su empleo en la producción de palma de jipi es una alternativa económica y amigable con el ambiente. El objetivo del estudio fue evaluar el efecto de vermicomposta durante 120 días, en el desarrollo y crecimiento de la hoja de Carludovica palmata R. & P. en una parcela experimental en Santa Cruz Ex‑Hacienda, Calkiní, Campeche. El diseño experimental utilizado fue cuadrado latino, con seis tratamientos y seis repeticiones. Los tratamientos empleados fueron: T1 = 0 Mg ha-1 de vermicomposta, T2 = 5.3 Mg ha-1 de vermicomposta, T3 = 10.6 Mg ha-1 de vermicomposta, T4 = 15.9 Mg ha-1 de vermicomposta, T5 = 10.6 Mg ha-1 de vermicomposta + 0.22 Mg ha-1 de Triple 17 y T6 = 0.22 Mg ha-1 de Triple 17 EM®. No se encontraron diferencias significativas (P > 0.05) en el número de hijuelos, hojas y cogollos entre los tratamientos como tampoco en el testigo; las plantas con el tratamiento T4 incrementaron significativamente la longitud de la hoja, peciolo y limbo con respecto al testigo. En los estadios, los tratamientos T4 y T5 presentaron diferencia significativa en una mayor frecuencia de cogollos con peciolo visible y hojas abiertas respectivamente. El uso de vermicomposta repercutió positivamente en caracteres como producción de cogollos, longitud y reducción de la mortalidad de las hojas.

El experimento se realizó en condiciones de invernadero, a través de un diseño experimental de bloques completos al azar con cuatro repeticiones. De acuerdo a los resultados se encontró que la aplicación de B. subtilis incrementó significativamente la altura de plantas respecto al testigo, así mismo la aplicación de B. subtilis y T. harzanium incrementó el volumen de raíz. Se observó que existen diferencias estadísticas en los contenidos de lípidos y proteínas en el fruto de plantas biofertilizadas con T. harzanium, y que en los frutos de plantas tratadas particularmente con B. subtilis y T. harzanium se acumulan mayores cantidades de fósforo.

A pesar de algunos esfuerzos de reforestación, México pierde alrededor de 500 000 ha de bosques templados anualmente, lo cual libera a la atmósfera el carbono contenido en el tejido vegetal, mantillo y suelos. Gran parte de estos bosques se encuentran en suelos de origen volcánico que ocupan el 1.2% del territorio nacional, pero existe poca información acerca del almacenamiento de carbono en suelos, mantillo y vegetación arbórea sobre estos suelos. Por esto, el objetivo de esta investigación fue determinar las concentraciones de carbono orgánico en el arbolado, mantillo y suelos en el área natural protegida (ANP) El Faro en Tlalmanalco, Edo. de México. Se seleccionaron ocho sitios de muestreo bajo cuatro categorías de cobertura arbórea: Cupressus-Pinus, Pinus-Quercus, Quercus-Pinus y Quercus. Se determinó la especie y el diámetro normal (DN) de los árboles mayores a 10 cm de DN, se colectaron muestras de mantillo y de suelo de 0 a 20 cm de profundidad. En laboratorio, se determinaron las concentraciones de carbono orgánico del suelo (COS), densidad aparente, porosidad, y volumen de rocas. Se estimó el carbono total en arboles por especie con base en fórmulas alométricas. Se almacena en promedio 185.34 Mg ha-1 en total: 56.40 Mg ha-1 en la vegetación arbórea, 44.91 Mg ha‑1 en mantillo y 84.03 Mg ha-1 en suelo. La cobertura arbórea Pinus-Quercus almacena más carbono en el arbolado con 71.74 Mg ha-1, y entre todos los sitios existe una correlación positiva entre la biomasa arbórea total de Quercus con el COS. Esto probablemente se debe a la acumulación y descomposición más rápida de su hojarasca comparado con las acículas de Pinus spp. Estimamos que se almacena un total de 9267 Mg de carbono en las 50 ha de bosque templado del ANP El Faro, contenido que se liberaría si el área se deforesta, evidenciando la importancia de su conservación.

Con el objetivo de caracterizar el suelo del agroecosistema maíz con los sistemas de producción convencional, agroecológico y mixto, para documentar e identificar estrategias que consideren los aspectos ambientales, sociales y económicos que conlleven a alternativas para la producción sostenible, se estudiaron las propiedades físico-químicas y biológicas de 35 muestras obtenidas en 28 ejidos de la región Frailesca, interpretadas con la Norma Oficial Mexicana NOM-021-RECNAT-2000. Los resultados indican una acidez generalizada para los tres sistemas con un pH de 5.05, 5.25 y 5.24, la capacidad intercambio catiónico es baja (13.96, 12.54, y 14.95 cmol(+) kg‑1) y niveles medios de materia orgánica (3.5, 2.58 y 3.45%). Así mismo, los macronutrientes, como el fósforo se encuentra en niveles altos (75.36, 74.78 y 45.05 mg kg‑1) y el potasio se encontró en niveles bajos (3.86, 3.12 y 2.66 mg kg‑1) y los micronutrientes se encuentran en niveles medios como el hierro (3.24, 2.03 y 2.62 mg kg‑1) y boro (1.58, 1.06 y 1.37 mg kg-1). Para el caso de la textura del suelo presentan suelos franco-arcillo-arenoso y franco-arenoso. Desde el punto de vista de las características biológicas del suelo, la macrofauna con el sistema agroecológico reportó mayor diversidad de seres vivos de acuerdo al índice de Shannon y Weaver (H’ = 1.121), destacan coleópteros, anélidos, himenópteros, isópteros y gasterópodos. En ese mismo sentido, para el caso de microorganismos sobresale en diversidad de microorganismos (H’ = 1.121) reportando entomopatógenos (Beauveria bassiana y Metarhizium anisopliae), fijadores de nitrógeno (Rhizobium, Azotobacter y Azospirillum) y hongos patógenos como Rizhoctonia, Fusarium y Alternaria y el sistema con menor diversidad fue el convencional con H’ = 0.789. Bajo estas condiciones el suelo, es necesario una estrategia que permita aumentar la calidad y las prácticas de agricultura puedan ser sostenibles.
EARTHWORM BIODIVERSITY IN DIFFERENT LAND USE SYSTEM
Authors: Rai S.N.
Published: November 2020

Researches have proved that the occurrence of different species of earthworms in good numbers is a positive sign of healthy soil. Establishment of earthworm population makes the soil more compact and the poor structure of deep soil changes in to friable top soil. Twenty two species of earthworms are identified from different land use systems. The potential soil reclaiming species are Eutyphoeus incommodus, Eutyphoeus nicholsoni, Eutyphoeus waltoni, Octochaetona surensis, Amynthas morrisi, Metaphire posthuma and Lampito mauritii. Metaphire posthuma is very abundant in garden soils. Eutyphoeus nicholsoni is mostly confined to garden litter soil with medium and low population as deep burrowing species. Octochaetona surensis is very common in dense bamboo plantations. Amynthas morrisi is mostly confined to decomposing paddy straw and composting litter. The cultivated soils of sugarcane and jowar, the species association index of Eutyphoeus incommodus and Ramiella naniana is very high though Ramiella naniana is purely a geophagous species. Seeds of earthworms can easily be transported if they are properly packed in vials with water soaked filter paper. The seeds will not hatch out within 10 days from the date of their laying.
SAMPLE STANDARD DEVIATION(s) CHART UNDER THE ASSUMPTION OF MODERATENESS AND ITS PERFORMANCE ANALYSIS
Authors: Tailor Kalpesh S.
Published: November 2020

Moderate distribution proposed by Naik V.D and Desai J.M., is a sound alternative of normal distribution, which has mean and mean deviation as pivotal parameters and which has properties similar to normal distribution. Mean deviation (δ) is a very good alternative of standard deviation (σ) as mean deviation is considered to be the most intuitively and rationally defined measure of dispersion. This fact can be very useful in the field of quality control to construct the control limits of the control charts. On the basis of this fact Naik V.D. and Tailor K.S. have proposed 3δ control limits. In 3δ control limits, the upper and lower control limits are set at 3δ distance from the central line where δ is the mean deviation of sampling distribution of the statistic being used for constructing the control chart. In this paper assuming that the underlying distribution of the variable of interest follows moderate distribution proposed by Naik V.D and Desai J.M, 3δ control limits of sample standard deviation(s) chart are derived. Also the performance analysis of the control chart is carried out with the help of OC curve analysis and ARL curve analysis.
DIMINUTION OF REAL POWER LOSS BY VALUE-ADDED BAT ALGORITHM
Authors: Lenin K.
Published: November 2020

In this paper, a new Value-added Bat Algorithm (VBA) is proposed to solve reactive power problem. Echolocation is a significant feature of bat behavior and it produce a sound pulse and listens to the echo bouncing back from obstacles whilst flying. Projected VBA algorithm utilizes chaotic behaviour to produce a candidate solution in behaviours analogous to acoustic monophony.  Proposed VBA has been tested in Standard IEEE 118 bus system & practical 191 Indian utility system and simulation results show clearly the better performance of the proposed algorithm in decreasing the real power loss.

The transmembrane protein zonula occludens of rectal tissue has function to prevents the spread of bacterial toxins into the intestinal mucosa and to systemic circulation. But radiotherapy causes ablation of crypt cell proliferation, mitotic catastrophe, and apoptosis leading to gastrointestinal mucositis. We investigated the acute radiation effect on gastrointestinal mucosa of rectum tissue thickness with immunohistochemistry method for zonula occludens-1 (ZO-1) protein in animal model.

A total of 24 healthy Swiss Albino mice were divided into 4 groups, and except control group the groups of 1–3 was exposed to 500 cGy total body irradiation. All rectum tissue samples were taken from the groups of control, 24 h, 72 h, and 168 h after irradiation and stained with hematoxylin and eosin for histochemical examination, and for immunohistochemical staining with anti ZO-1 polyclonal antibody.

We observed edema especially in the groups 2 and 3 but not in group 1.  Immunohistochemical examination of staining of rectum tissue samples for ZO-1 showed poor staining for control group (1.48 ± 0.06) and group 1 (1.38 ± 0.09) and group 2 (1.50 ± 0.01) but the group 3 (2.12 ± 0.04) samples showed moderate ZO-1 immunostaining. It was found that the amount and thickness of ZO-1 expression increased in the late period for more than 24 hours. The comparison of the values of ZO-1 between the group 3 which is the group in the late period after radiation exposure and control group or group 1 or group 2, showed statistically significant differences (p <0.001).

It was concluded that ZO-1 protein may have a role in the side effects of radiation injury, and the understanding of cellular and molecular activity will help us to develop pharmacological modulators to mitigate or treat the injury.
Skills management in regional economic policy of the OECD and the EU member countries
Authors: Kokovikhin Aleksandr
Published: November 2020

The paper analyzes the theoretical concepts and practice of skills management implemented in the countries of the Organisation for Economic Cooperation and Development (OECD) and the European Union (EU). The relevance of the study is due to the lack of data about the OECD and the EU experience examined in the Russian literature in terms of theoretical comprehension of gaps and mismatches in employees competencies, jobs requirements and the skills management policy at state and regional levels. This problem not only significantly narrows the Russian research field, but also deprives regional authorities and self-government specialists of access to approved management tools. The methodological background of the study is the competence-based approach that provides necessary tools for both theoretical conceptualization and the development of an appropriate state policy. In the paper, we apply the methods of comparative and system-based analysis of the theory and practice of competency management at regional level. Using them, the author discusses the role, content and toolkit of state and regional policy on skills management, and analyzes how theoretical concepts of new public management, knowledge economy and institutional economy affect the development and implementation of the strategic documents of the OECD and the EU, as well as member countries and regions in a historical perspective. The research findings indicate a general trend towards change in the priorities of the regional skills management policy from competency supply management in 2000–2007 to the balanced development of competency demand and supply in 2007–2015 and focusing on skills in breakthrough technologies that underlie the region’s smart specialization. The research also reveals the special features of regional skills management policy in particular countries. The research results can be used for further theoretical analysis of state policy in regional labor markets, as well as in the development of strategies and policies for managing labor resources at the level of Russia’ regions.
