Forest conversion activities into non forestry purposes impacts on decreasing of forestfunction as a main role sustainable development, especially as water regulators and as carbon storage. Therefore, deforestation not only causes a direct loss of forest habitat but also leads to indirect impacts as ecosystem services deteriorate or fail. Forests provide ecosystem services that include the regulation of weather and climate at local, regional and even global levels. Existence of protected forest Pinang Luar ± 3.228 acres take an important part and people living in the area has a high dependency on the forest. Farming activities become a treat to the forest and their indications show that cropland and palm estate already in the forest area. Land cover changes in protected forest Pinang luar at 2003 – 2012 impacts on villages at ring 1 area hierarchy decrease cause by population growth are not followed by the additional of infrastructures in economy, health and education. It is also caused by landconversion that occurred in the protected forest Pinang Luar. In the period 2003 - 2012, the villages directly affected (ring 1) have a level area hierarchy is much worse compared to villages that are not directly affected (Ring 2). And it affected to the development of the villages in the ring 2 which is better than the village at ring 1. These conditions happen because at the village in ring 1 change only on land not on the impact on the level of development that could affect the region hierarchy. This is in contrast with the ring 2 villages where the changes occur not only on land but also on its impact on the development so as to enhance the region hierarchy in ring 2 villages.Key words : forest conversion, hierarchy level, ring 1 village, ring 2 village.

The role of digital consciousness in change management
Authors: Akperov I. G. , Martynov B. V. , Prokopenko E. S.
Published: December 2022

The article deals with the problems of change management in the new conditions of superfragility of the BANI-world. Interpretations of the concepts of “transcendental thinking”, “digital consciousness”, “immersiveness” are given. The prerequisites substantiating the idea that transcendental thinking needs to be cultivated in the organisation in order to achieve effective management flexibility are presented. The latter is formed in the broader context of the digital consciousness organisational culture, without which it is impossible to set up the organisation’s staff for a positive perception of immersive management practices and the digital technologies productive use. Barriers to the transformation of organisational processes have been identified. It has been shown that the digital transformation of the organisation increases the resistance on the part of the staff by digital resistance plane, when aversion to any change correlates with a lack of ­understanding of digital opportunities. The relationship between the conceptual methodologies of digital consciousness and metacognition and the effectiveness of the formation of a change management strategy has been established.
The municipalities’ environmental situation assessment as a basis for customizing strategies
Authors: Trifonova P. S.
Published: December 2022

The article reveals the issues of assessing the ecological situation of municipalities. Based on an analysis of the socio-economic development strategies of municipalities in the Sverdlovsk region, it has been concluded that they lack the disclosure of the strategic direction “Ecology” in them, which can become the basis for the individualization of strategies. The article presents the author’s approach to assessing the tension of the ecological situation of the territories, which makes it possible to identify the most acute environmental problems. A multi-stage algorithm for calculating a complex and integral indicator of the intensity of the ecological situation of territories is proposed. The approach has been tested in three municipalities of the Gornozavodsk administrative district in the Sverdlovsk region. It has been concluded that the environmental situation in the Gornozavodsky administrative district is primarily determined by the industrial nature of activities and, consequently, by high levels of atmospheric air and water pollution.

Assessing the impact of personal income tax reforms on the income inequality dynamics in Russia in the 21st century
Authors: Dorofeev M. L.
Published: December 2022

The problem of regulating economic inequality to ensure social justice in society in the context of accelerating economic growth is of constant and obvious relevance. However, this problem does not have universal solutions due to significant country differences and the peculiarities of the social contract in a particular country. The purpose of this study is to analyse and assess the impact of reforms in the system of taxation of personal income on the dynamics of income inequality of Russian households. Dismantling the progressive personal income tax rate did not lead to a significant increase in income inequality in Russia, but the problem of excessive property inequality persisted until the beginning of 2022. The passive policy of regulating economic inequality unexpectedly yielded results in 2022. We expect, that after illegal confiscations and freezing of Russian assets abroad, coupled with anti-poverty programmes, the level of income and property inequality in Russia will significantly decrease on the horizon of 2022−2024. In the long term, the policy of passive financial regulation of inequality can produce a result that remains to be seen on the reporting data of Rosstat and international databases. In the future, when solving the dilemma between equality and economic growth, Russia should focus on the latter and make efforts to restore and then accelerate the growth of the average standard of living in the country.
Development of performance indicators for sustainable enterprises
Authors: Malevskaia-Malevich E. D.
Published: December 2022

The sustainable development of industrial enterprises presupposes a qualitatively new investment level aimed at the transition to the cleanest, least resourceintensive and most waste-free production possible through a continuous process of innovation and investment projects implementation. At the same time, the current conditions for real investment are generally associated with increasing uncertainty (in particular, due to globalisation and progressive technical development), and therefore are accompanied by a high risk level, which certainly affects the ongoing projects results. The purpose of this study is to develop indicators for assessing the enterprises effectiveness, taking into account the changing external environment, the processes of transition to sustainable development of the economy. The methods of analysis, synthesis and generalisation have been applyed. The results can serve as a justification for the widely used today in practice and in economic science, but insufficiently substantiated position that in market conditions the economic efficiency of an income-generating object can be assessed by its market value. The asset owner is always interested in increasing the market value, therefore, it is generally accepted that an increase in the market value over a certain period is also an indicator of the economic efficiency of the object use by the owner, and vice versa, a decrease in the market value of a facility indicates the presence of factors impeding effective operations.

Published: December 2022

Currently, the insurance market is actively using modern technologies, which allows companies to compete with each other and attract customers. However, the possibilities of introducing artificial intelligence and big data (AI and DB) into the regulated sphere, which is insurance, are usually limited compared to unregulated sectors. The purpose of the study is to substantiate the need and develop measures to regulate the use of AI in insurance, in general, and auto insurance, in particular, as well as to determine the prospects and risks of the spread of the use of AI technologies in insurance. The research used scientific works of domestic and foreign scientists in the field of AI and DB development in insurance, regulatory legal acts and program and strategic documents for the development of the Russian insurance market, as well as data generated by the authors on the basis of official statistical materials. For analytical data processing, the method of statistical analysis, the system-logical method, as well as such general scientific methods as induction, deduction and synthesis are used. The slowdown in the growth rate of the insurance market at the present time is due to both the tightening of the regulator’s requirements for the financial stability of insurers, and the lack of prospects for development, the complexity of the introduction of AI and DB in insurance. A competent state approach to regulating the activities of subjects in the topic under consideration entails a number of benefits and advantages, will allow to neutralize or reduce the influence of the identified constraining factors.

Published: December 2022

The Internet has become an integral part of the modern society. It has a strong influence on the social institutions and makes them adapt to the new conditions of the digital environment. Religion is not an exception despite its inherent resistance to change; such an ancient social construct was also forced to enter the process of digitalisation. The article reflects the peculiarities of this process: it analyses the activities of various religious movements in the Russian Federation in the digital environment and reveals the attitude of religious representatives (official and unofficial) to the process of adapting religion to the digital environment. The scholarly literature on the digitalisation of religion was analysed and the problematic aspects of this process were identified. A content analysis of the Internet communities and resources of the main traditional (Orthodoxy, Islam and Judaism) and non-traditional religious teachings (Neopaganism and Satanism)was carried out. We identified the attitude of religious representatives to the digitalisation of religion. We conducted an expert interview with bloggers whose activities are related to the dissemination of religious views on the Internet.

Published: December 2022

The article describes the experience of implementing a project approach to teaching in some universities of the Vologda region – Vologda State Agricultural Academy named after N.V. Vereshchagin and Cherepovets State University. The project approach is considered as the basis for the innovative development of educational institutions in the current context. The need for a project-based approach from the perspective of the student as an educational services consumer has been justified. The characteristics of the interaction forms between two universities in project activities are given, and the process of creating an inter-university project community during the pandemic of 2020-2021 is described. The creation of an inter-university project community is dictated by the need to develop methodological and practical tools to combine the educational potential of the two universities, as there is a demand for workers with a wide range of contemporary knowledge in today’s labour market. The tasks of university cooperation are outlined: organisation of interuniversity project teams; development of projects that include agricultural topics using contemporary technologies in the robotics field. The inter-university project community resulted in the merging of the two institutes’ disciplinary features and the development of two projects in the fields of biotechnology and agronomy with robotics processes.
The state of the art in core-shell type lipid polymer hybrid nanocarriers and beyond
Authors: Sengel-Turk Ceyda Tuba , ALPTÜRK Onur
Published: December 2022

The need to enhance the therapeutic effect of drugs and thus reduce their side effects is the reason for the emergence of today's drug delivery systems. With the advent of nanotechnology, numerous molecular structures - from carbon nanotubes to polymeric materials - have been developed, and significant progress has been made. However, all these promising results do not mean that drug delivery systems are a solution to all problems in pharmaceutical technology. This is because any drug delivery system, while having its advantages, also suffers from certain limitations. Therefore, new and hybrid structures are created by combining different materials. In this respect, lipid-polymer hybrid particles emerged as a core-shell structure, where the polymer core is covered with a layer of phospholipids, and have attracted attention in the academic community. This manuscript, which provides an overview of the fundamentals of these molecular architectures, begins with a description of lipid-polymer hybrid particles. Conventional and unconventional production methods for fabricating these structures are then described. This is followed by a section discussing how the physical properties of these particles are characterized and how the physical properties affect pharmaceutical activity. The final section discusses prominent examples from the literature.
Minimizing non-radiative decay in molecular aggregates through optimal control of excitonic coupling
Authors: Wang Yuanheng , Ren Jiajun , Shuai Zhigang
Published: December 2022

The widely known ``Energy Gap Law'' (EGL) predicts a monotonically exponential increase in the non-radiative decay rate (knr) as the energy gap narrows, which hinders the development of near-infrared (NIR) emissive molecular materials. Recently, several experiments proposed that the exciton delocalization in molecular aggregates could counteract EGL to facilitate NIR emission. In this work, the nearly exact time-dependent density matrix renormalization group (TD-DMRG) method is developed to evaluate the non-radiative decay rate for exciton-phonon coupled molecular aggregates. Systematical numerical simulations show, by increasing the excitonic coupling, knr will first decrease, then reach a minimum, and finally start to increase to follow the EGL, which is an overall result of two opposite effects of a smaller energy gap and a smaller effective electron-phonon coupling. This anomalous non-monotonic behavior is found robust in a number of models, including dimer, one-dimensional chain, and two-dimensional square lattice. The optimal excitonic coupling strength that gives the minimum knr is about half of the monomer reorganization energy and is also influenced by temperature, system size, and dimensionality.
Stereodivergent, Kinetically Controlled Isomerization of Terminal Alkenes via Nickel Catalysis
Authors: Rubel Camille , Ravn Anne , Yang Shenghua , Li Zi-Qi , Engle Keary , Vantourout Julien
Published: December 2022

Because internal alkenes are more challenging synthetic targets than terminal alkenes, metal-catalyzed olefin trans-position (i.e., positional isomerization) approaches have emerged to afford valuable E- or Z- internal alkenes from their complementary terminal alkene feedstocks. However, the applicability of these methods has been hampered by lack of generality, commercial availability, and scalability. In this Communication, we report a nickel-catalyzed plat-form for the stereodivergent E- or Z-selective synthesis of internal alkenes at room temperature. Under the developed protocols, conjugated and non-conjugated products that contain sensitive functional groups can be obtained in high yield and isomeric purity using commercially available catalysts and reagents. Notable mechanistic discoveries include the substoichiometric addition of an aryl iodide to enhance reactivity and selectivity for the synthesis of Z-isomers and the unusual finding of a phosphonium salt to enhance E-selectivity that we hope will inspire new perspectives on how these reagents interact with nickel centers.
What Matters More – Inherited Traits or Life Experiences? An Application of the Integrative Communication Theory in the Study of Cross-Cultural Adjustment and Assignment Satisfaction
Authors:   I. M. Sechenov First Moscow State Medical University, (Sechenov University), Muzychenko I. N.
Published: December 2022

Emotional stability and sense of coherence are both predictors of global quality of life, general life perception, psychological and physiological functioning. However, previous studies found these two concepts to overlap and called researchers to find more well-defined borders and study these two concepts. In the present study, I tried to address this issue using a mixed-method approach. I pretested the conceptual framework through the interviews conducted with 21 international students. I then measured the variables via a quantitative survey. Emotional stability and sense of coherence both enhancing cross-cultural adjustment processes and influencing assignment satisfaction. Later on, I analysed the direct effects, the mediating effect of cross-cultural adjustment and the role of cross-cultural motivation. Firstly, present levels of assignment satisfaction rather depend on personality traits than the time spent abroad, probably due to the stress-adaptation-growth dynamics. Secondly, the extent to which students feel satisfied with their cross-cultural adjustment in general affected their thoughts about assignments. Thirdly, the satisfaction-wise benefit of having high motivation to fit in a new culture was bigger in students who had higher sense of coherence, and lower in those with lower levels of it.

The Universal Genre Sphere: A Curricular Model Integrating GBA and UDL to Promote Equitable Academic Writing Instruction for EAL University Students
Authors: David Rosa Dene , Anderson Carl Edlund
Published: December 2022

This paper proposes the design of an instructional model, referred to as the universal genre sphere, for teaching academic writing in a manner appropriate to all learners, but developed especially with consideration for the needs of English as additional language students with or without diagnosed learning differences. Despite growing research on, variously, second-language writing, English as an additional language and learning differences, there has been relatively little work that explores approaches to the intersections of these topics. Thus, the proposed universal genre sphere model is founded on the pillars of universal design for learning and the tenets of the genre-based approach, especially the teaching-learning cycle, to create more equitable and inclusive, as well as effective, learning environments. The universal genre sphere balances inclusive design that draws upon students’ interests, while breaking learning into manageable and adjustable segments, thus making academic writing more accessible to a greater number of learners. The combination of universal design for learning and the genre-based approach represents an opportunity to create a shift in second-language writing instruction (and, potentially, in L1 writing instruction) that aligns with the principles of inclusive education by reducing barriers in the classroom and providing students with multiple pathways to participate, which could do much to advance knowledge about more inclusive, equitable and effective writing instruction for all learners.

Використання інформаційно-вимірювальних систем на підприємствах нафтогазової галузі дає змогу покращити облік витрати газу. З усіх відомих методів вимірювання витрат детально вивчено, відпрацьовано і доведено до стандартизованих у повному обсязі тільки метод змінного перепаду тиску. Тенденції розвитку витратомірної техніки останніх років дозволяють вважати ультразвуковий метод одним із кращих завдяки, зокрема, можливості безконтактного вимірювання будь-яких речовин, надійності приймально-передавальних елементів, що зумовлено відсутністю рухомих частин, і, теоретично, необмеженим діапазоном вимірювань. Розглянуто принцип вимірювань витрат газу за допомогою ультразвукового перетворювача витрати (УЗПВ), заснований на тому, що ультразвуковий імпульс, спрямований уздовж потоку, поширюється швидше за ультразвуковий імпульс, що спрямований проти потоку. Наведено методику розрахунку витрати газу, приведеного до стандартних умов (Р = 0,101325 МПа, Т = 293,15 °К). Розглянуто методику розрахунку оцінки похибки вимірювань при обмеженій вихідній інформації, коли для засобів вимірювань (ЗВ) нормовані лише такі метрологічні характеристики: межі значень основної похибки, що допускаються; межі значень додаткових похибок, що допускаються при найбільших відхиленнях зовнішніх впливових величин від нормальних значень, або максимально допустимі значення коефіцієнтів впливу.

У статті розглядається стиснення цифрових даних вимірювальної відеоінформації. Таке стиснення є складовою частиною процесу перетворення даних у комп’ютеризованих інформаційно-вимірювальних системах, що призначені для вимірювання лінійних і кутових переміщень об’єктів. Стиснення часових послідовностей відеозображень, що містять вимірювальну інформацію про геометричні параметри та параметри руху об’єктів, необхідне для підвищення точності та швидкодії засобів вимірювання механічних величин. Таке стиснення дозволяє суттєво зменшити об’єм цифрових даних відеозображень. У результаті зображення передаються по комп’ютерним мережам з прийнятними показниками швидкодії та зберігаються в пам’яті. Стиснення відеозображень приводить до виникнення похибок вимірювальної інформації та відповідно, знижується точність визначення геометричних параметрів та параметрів руху об’єктів. Запропоновано математичну модель похибок вимірювальної інформації на стиснутих відеозображеннях. Ця математична модель дозволяє визначити вплив стиснення на точність вимірювань геометричних параметрів та параметрів руху об’єктів залежно від параметрів алгоритму стиснення. На основі математичної моделі похибок вимірювальної інформації визначено параметри методу JPEG, які доцільно використовувати при стисненні відеозображень у часовій послідовності, що відображає геометричні параметри та параметри руху об’єктів. Це дозволяє підвищити точність вимірювань за рахунок фільтрації шумів, що виникли в процесі формування відеозображень. Наведено експериментальну оцінку похибок вимірювань, пов’язаних зі стисненням.

Розглядаються результати ідентифікації металевих об’єктів вихрострумовою радіотехнічною системою (РС) з амплітудно-фазовим детектуванням сигналу відгуку при їх динамічному скануванні. Розроблено математичну модель, яка описує зміни інформаційних критеріїв сигналу відгуку залежно від матеріалу досліджуваних металевих об’єктів та швидкості лінійного переміщення їх відносно антени РС. Проведено моделювання сигналів відгуку для декількох металів та наведено порівняння із отриманими експериментально результатами. Визначено оптимальний діапазон швидкостей сканування, який дозволяє отримати максимальну кореляційну різницю інформаційних критеріїв для різних металів, яка записується у запам’ятовувальний пристрій і використовується для подальшої ідентифікації невідомих провідних (металевих) об’єктів. Запропонована математична модель сигналу відгуку вихрострумового пристрою з фазовим детектором та інтегрально-диференційний підхід до визначення кореляційної різниці інформаційних критеріїв спектрального та графічно-цифрового методів ідентифікації металевих об’єктів дозволила експериментально визначити діапазон оптимальної швидкості руху металевого об’єкта відносно антенної системи. Отримані експериментальні результати показали, що максимум кореляційної різниці інформаційних параметрів запропонованої радіотехнічної системи лежить у діапазоні 12–14 Гц, що відповідає діапазону лінійних швидкостей 4–6 м/с.

Якісною системою сповіщення вважається та, яка формує достовірний сигнал тривоги та мінімізує помилкові спрацьовування. Для максимальної продуктивності системи сповіщення доцільно використовувати комбінований варіант, що буде наділений внутрішнім «інтелектом», який дозволить виявити небезпеку, сповістити про неї, а також за необхідності нейтралізувати загрозу. Використання комбінованого сповіщувача, який, крім надсилання сигналу небезпеки, одночасно надсилає і фотографію приміщення, що охороняється, суттєво підвищить вірогідність правильного виявлення небезпечної ситуації і зменшить ймовірність хибної тривоги. У роботі показана можливість створення комбінованої системи дистанційного контролю за несанкціонованим проникненням до приміщення та пожежної сигналізації на основі недорогого модуля ESP32-CAM, який ідеально підходить для самостійних проєктів у галузі IoT.

Мікроклімат приміщень – це комплекс фізичних факторів внутрішнього середовища приміщень, що впливає на тепловий обмін та здоров’я людини. Мікроклімат визначається діючим на організм людини поєднанням температури, вологості, швидкості руху та чистоти повітря. Якщо мікроклімат не відповідає нормі, погіршується самопочуття, з’являються скарги на задуху, утруднення дихання, тяжкість у голові, головний біль, пітливість, сонливість, падіння розумової, а потім і фізичної працездатності.  Санітарними нормами передбачені допустимі мікрокліматичні умови, за яких зміни функціонального стану організму не критичні. Вивчення цього питання набуває особливої значущості в умовах сьогодення, коли спостерігаються тенденції до погіршення стану здоров’я студентів та персоналу. Для вирішення проблеми моніторингу мікроклімату приміщення в роботі пропонується розробка автономної інфокомунікаційної системи вимірювання кліматичних параметрів, таких як температура, відносна вологість повітря, рівень вуглекислого газу в повітрі та концентрація легких аероіонів із записом даних на смартфон та збереженням на віддаленому сервері. Розробка є частиною системи з дослідження впливу параметрів мікроклімату на фізіологічний стан здобувачів освіти. Результати, отримані в роботах, дозволять розробляти заходи по забезпеченню необхідних нормальних умов навчання студентів у замкнутих приміщеннях. Також розроблена система може використовуватися для моніторингу мікроклімату в герметично замкнутих військових об’єктах – ракети, літальні апарати, танки тощо.

Інтенсифікація машинобудівної галузі сьогодні пов’язана з розробкою новітніх методів дослідження процесів виготовлення деталей машин та із вдосконаленням високошвидкісних процесів різання. В промисловості все частіше впроваджують процеси металообробки інструментами із надтвердих матеріалів, що дають значне підвищення продуктивності, якості оброблюваної поверхні та вдосконалення режимів різання лезовим інструментом. Усі ці параметри визначаються багатьма факторами, а саме конструктивними та геометричними елементами різальної частини, матеріалом різального інструменту, стружкоутворенням, умовами охолодження різальних кромок, що в подальшому формує умови для вибору продуктивних режимів різання. Вибір матеріалу інструментів є одним із найважливіших параметрів, що забезпечує високу продуктивність процесу різання. Поширеного застосування здобув полікристалічний кубічний нітрид бору групи BL для лезових інструментів. Але під час високоінтенсивних процесів обробки постають питання з оптимізації температурних полів у зоні обробки. Ще більш складним завданням є дослідження процесів високошвидкісної обробки з визначенням температурних режимів та технологічних процесів як в науковому середовищі, так і безпосередньо в промисловому виробництві. Вирішення цих завдань може бути здійснено шляхом моделювання робочих процесів різання, зокрема застосуванням методу скінченних елементів, що дасть побудову нових моделей у термобаричних процесах під час різання.

Goal. To give a system of arguments proving that the experience of spatial development of the national economy of the USSR in the Arctic region should not only be used to the maximum, but also scaled up to ensure inclusive, involving all segments of the population and increasing their well-being of the development of the modern economy of Russia. Tasks. To prove the necessity and determine the main directions for the creation and functioning of a large transport and transit corporation in the Arctic region - a modern superorganization following the example of the spatial development of the USSR. To pay special attention to the directions of ensuring inclusive growth of the Arctic economy through the development of North-South trade routes and strengthening the economic sovereignty of Russia. Methodology. The research uses the methods of system analysis, evolutionary and institutional theory, the theory of production and technological balance and technical and economic structures, expert and analytical assessments, content analysis of periodical materials. Results. It is determined that the priority project should be the construction and year-round transit use of the Great Northern Railway (VSP) and the North-South transport corridor in order to multiply the export of transport services in the Arctic zone. It is established that after the collapse of the USSR and the independence of the countries of Central Asia and the South Caucasus, the spatial organization of the Russian economy took on an even greater northern, Arctic character. The increase in the priority of the development programs of the Russian Arctic should be accompanied by the establishment of cooperation and strengthening of integration with the southern states of the Eurasian space, the infrastructure basis of which will be the new trade routes of the XXI century in the direction of «North - South» and the development of their innovation and industrial belts. Conclusions. On the basis of historical and economic studies and analysis of the experience of spatial development of the national economy of the USSR, the conclusion is made about the relevance and necessity of creating and developing new organizational and institutional forms of functioning of the Arctic economy, the formation of trade routes of the XXI century and their innovative and industrial belts both in the direction of «East-West» (the Northern Sea Route, the Great Northern Way) and «North-South» (the Arctic Ocean - Indian Ocean transport corridor).

The article analyzes the features of the functioning of the Russian-speaking economy in two countries of the European Union — Hungary and Austria. The study is based on data from national statistical offices, Eurostat data, an analysis of online job sites, as well as on the basis of surveys conducted during 2020-2021 with representatives of Russian-speaking communities living in these countries. It is shown that in both countries at present the main channels for the formation of Russian-speaking communities are labor migration, marriage migration, family reunification and educational migration. The Russian-speaking economy in Austria includes a chain of Russian grocery stores, small hotels, hairdressers. In the period before the pandemic, Russian-speaking guides were in demand. Doctors and lawyers with knowledge of the Russian language are also focused on the Russian-speaking population of Austria. The Russian-speaking economy is mainly represented in Vienna and a number of large Austrian cities — tourism centers. In Hungary, the Russian-speaking economy also relies primarily on consumers of Russian goods and services. The Russian-speaking segment of the Hungarian economy is developing due to the demand for the country among Russian tourists, tourists from other countries of the post-Soviet space, where the proportion of the population that speaks Russian is large. Russian-speaking employees are also involved in international companies that have their offices in Hungary.
