Політики та зацікавлені сторони часто стикаються зі складним завданням розподілу ресурсів і уваги між різними регіонами в пошуках збалансованого та сталого розвитку. Методологія визначення пріоритетів у політиці регіонального розвитку відіграє ключову роль у прийнятті цих рішень, забезпеченні ефективного використання ресурсів і стимулюванні справедливого зростання. Встановлено, що прогнозування регіонального розвитку будується у відповідності із загальними принципами прогностики і територіального прогнозування, а, саме: системність і узгодженість, варіантність і неперервність, достовірність і точність прогнозів. Запропоновано Форсайт-технологію як метод прогнозування використовувати як ефективний інструмент стратегічного планування розвитку країни чи окремих її регіонів. Проблеми регіонального розвитку є слабко структурованими, тому що саму постановку задачі не вдається описати моделлю, яка представляється функцією багатьох змінних, що приймають числові значення, цільова функція не має чітко вираженої мети, не розроблені алгоритми отримання числових рішень. Політика регіонального розвитку є двовимірною, тобто включає безпосередньо політику держави щодо регіонів, метою якої є забезпечення геостратегічних інтересів держави на основі переважного використання централізованих фінансових ресурсів, і політику регіонів, спрямовану на ефективне здійснення відтворювальних процесів в економіці, соціумі і природному середовищі, для реалізації якої потрібна підтримка держави. Стратегія регіонального розвитку не визначає конкретні напрямки діяльності обласної та місцевої влади в тому, що стосується поліпшення умов і забезпечення розвитку регіону, але чітко вказує на те, що органи місцевого самоврядування та виконавчої влади відіграють ключову роль у визначенні напрямків розвитку регіону. Методологія визначення пріоритетів у політиці регіонального розвитку є дороговказним компасом у складному ландшафті регіональних розбіжностей і проблем розвитку. Завдяки структурованому підходу, аналізу даних, участі та можливості адаптації ця методологія пропонує політикам потужний інструмент для навігації в тонкощах сприяння збалансованому та сталому зростанню в різних регіонах.

Published: December 2023

Повномасштабне вторгнення росії в Україну, яке розпочалося 24 лютого 2022 року, призвело до тяжких наслідків для освіти в Україні. Заклади освіти зазнали людських втрат – під час бойових дій гинули та продовжують гинути викладачі, здобувачі освіти та батьки. Тисячі закладів освіти було зруйновано або пошкоджено. Мільйони дітей і тисячі українських викладачів були вимушені змінити місце проживання всередині країни або виїхати за кордон. Щодня всі учасники освітнього процесу мають долати виклики війни: вимушені перерви у навчанні, перехід на дистанційну або змішану форму навчання, повітряні тривоги та відключення електроенергії. Повномасштабна війна погіршила доступ до освіти, поглибила наявні освітні нерівності, негативно вплинула на якість освітнього процесу й успішність, а також відобразилася на психоемоційному стані здобувачів освіти. Звісно, що війна в Україні, вплинула й на інклюзивну освіту. Однак держава робить все можливе і не можливе, для того, щоб в таких складних умовах, інклюзивна освіта забезпечувала можливість отримання освіти усіма членами соціуму. Певні зміни до нормативно-правового забезпечення інклюзивної освіти, передбачають, що у період воєнного стану, надзвичайної ситуації або надзвичайного стану (особливого періоду) заклади освіти не можу відмовити в організації інклюзивного навчання дітей з особливими освітніми потребами та створенні інклюзивного класу (групи). В умовах воєнного стану здобувачі освіти з особливими освітніми потребами є найбільш вразливою категорією, яка потребує виняткової підтримки та уваги. Тож, незалежно від місця їх перебування заклади освіти мають прикласти всі зусилля, аби такі діти продовжили здобуття освіти та отримали необхідну психолого-педагогічну допомогу у безпечних умовах. Адже розвиток економіки держави на сучасному етапі в умовах глобалізації характеризується активізацією процесу інтелектуалізації та формуванням на цій основі суспільства, що базується на знаннях і високих технологіях, відрізняється високим інноваційним та інтелектуальним рівнем.

Objective: To estimate the expected quantitative changes of the rainfed sugarcane yield in four sugar mills in the state of Veracruz using climate change scenarios for the end of the 21st century and considering that the same climate change could also affect soil fertility.
Design/methodology/approach: The data on the cultivated area with the rainfed sugarcane such as topography, principal properties of soil fertility, crop yields for the beginning of the 21st century, current climatic data from the meteorological stations and future ones based on existing climate change scenarios were analyzed. Then, by means of a physiological model of this crop based on biological, climatic and soil characteristics, proposed by IIASA/FAO, the current and future agricultural productivity of sugarcane was calculated. The actual productivity calculated with this model was compared with the observed data. Then, the productivity of this crop for the end of the 21st century was calculated. The comparative impact on the productivity of the expected changes in some climatic components and corresponding expected modification in soil fertility was assessed.
Results: The results of calculations indicate that if the CO2 concentration in the atmosphere increases by 2 or 2.7 times at the end of the 21st century and the current varieties of sugarcane and their crop management will conserve, the yield of sugarcane will decrease up to 20% depending on the climate change scenario and location of the plot. The main climatic factor influencing the decrease in sugarcane productivity is the expected decrease in precipitation.
Limitations on study/implications: Monthly average climatic variables are used for both current and future productivity calculations since there are no estimates of daily data. There are also no predictions on the development of crop management technology as well as on the expected change in pests and diseases for the end of the 21st century.
Findings/conclusions: The IISA/FAO physiological model of sugarcane growth based on agroecological principles, considering even limited number of climatic variables, is useful for calculating of sugarcane productivity with correlations greater than 90% for calculated and observed data. This allowed us to estimate the expected impact of climate change in the productivity of rainfed sugarcane in Veracruz State of Mexico at the end of 21st century.

Authors: Álvarez-Hernández Juan C. , Castillo-Martínez Carlos R.
Published: December 2023

Objective: To evaluate outstanding and adapted papaya lines derived from selection to conserve desirable characteristics. Design/methodology/approach: 23 lines of the 'Maradol' type were evaluated at Antunez Michoacan, Mexico. Initially, the plants' height, stem circumference, number of leaves, and first fruit height were recorded. During their development, outstanding plants were identified, and their self-pollinating was promoted. In the fruits, their polar and equatorial circumference, shape index, weight, width and pulp firmness, and soluble solids were assessed. Results: The plants' development was different, their variability between lines allowed identifying morphological characteristics of interest. Only 10 lines had this condition. The number of fruits formed over covered flower buds and collected fruits on formed fruits was reduced. The fruits´ characterization, except for their soluble solids, showed differences. Multivariate analysis indicated variability associated with each principal component. Limitations on study/implications: Currently in Mexico, there are few papaya varieties, the 'Maradol' variety being dominant, and vulnerable to phytosanitary problems over time. However, developing varieties and seed production is challenging and the pollination control of the plants necessarily intervenes. Findings/conclusions: Out of 23 assessed papaya lines, only 43.48 % reported outstanding plants. Inside these lines, between 5 and 10 % of the plants were chosen. In the developmental progress from the covered flower buds’ stage to formed and collected fruits, only 28 % of fruits were obtained. The selected lines showed fruit variability.

Published: December 2023

On the basis of substandard beidellite clay and oil sludge, a lightweight brick with high technical indicators was obtained. It is advisable to use oil sludge as a thinning agent and a burnout additive. The addition of an optimal amount of oil sludge (30%) to the ceramic mass makes it possible to obtain a lightweight brick of the M100 brand. Underthe optimal content of oil sludge in this work, such an amount is taken, at which the number of plasticity of the ceramic mass (charge) decreases from 18 to 10, since with a smaller number of plasticity of the charge, cracks appearon the products during molding. The study of the phase composition showed that the introduction of oil sludge into the composition of ceramic masses contributes to an increase in anorthite and the formation of diopside. Diopside contributes to the production of high-strength building ceramics in a composition with low-melting clays. Moreover,when diopside is introduced into the raw material, the hardening effect begins in the temperature range of 900-1050°C.

Features of functioning of the pipeline transport systems in the conditions of repair, reconstruction or preservation of separate parts are considered. It is shown that the structural changes connected with it create additional risksfor end users of a target product. Transition to a condition of nonserviceability of some set of pipelines is considered as process of the progressing damage which development leads to disconnection from a source at first parts, and then and all consumers. The ability of a system to resist to development of the progressing damage is characterized by the firmness indicator representing an average share of pipelines which accidental transition to a stateof nonserviceability brings to disconnection from a source of all consumers. It is offered to provide the required level of firmness of the recovered system by the choice and implementation of the rational scheme of shutdownof the repaired pipelines. The algorithm of the choice of rational schemes of shutdown of pipelines in dependence of conditions of preparation and implementation of repair is formulated.
Pluralization of Social Media Loan Terminology in Colloquial Arabic
Authors: Al-Jarf Reima
Published: December 2023

Arabic has ancient as well as contemporary loanwords from numerous languages such as English, French, and Turkish that are used as loan words or in code-switches. With the advent of social media, the number of foreign words used in the spoken language is on the rise. This study aimed to find out how social media loan terminology is pluralized in Spoken Arabic and whether there are any pluralization peculiarities that were not detected by prior studies. To identify the plural formation processes followed in each loan term, a sample of 20 students and 5 instructors at the College of Language Sciences, King Saud University participated in the study. The participants verified a 146 social media loan terms to verify the plural form of each. Results showed that 54% of the loan terms in the sample take a Feminine Sound Plural (account اكاونتات /akaynt-a:t/, which is the most productive plural form. In 16% of the loan terms in this category, the final consonants in the stem are geminated before the suffix -a:t when the penultimate vowel in the stem is short as in blogs بلوجات /blogga:t/; clicks كليكات /klikka:t/; stories ستوريات /sto:riyya:t/. In other terms, an /h/is added to the plural suffix -a:t in stems ending in the long vowel و /u;/as in studios استديوهات /studio-ha:t/. About 22% of the loan terms take a zero plural (voice call; timeline; status; 17.6% have the English plural form ending (followers; threads); only 3% take a Masculine Sound Plural فيسبوكييون /feysbukkiyyu:n/ (*Facebookers) and 3% have a Broken plural (codes أكواد /?kwa:d/); 3% have two plurals (code كودات /ko”da:t/, أكواد /?akwa:d/; Youtubers اليوتيوبرية /yu:tu:bariyya/ & يوتيوبرز /yu:tyu:barz/; and in one loan term, the Feminine Sound Plural is added to the plural form (fans+ -a:t). As in prior studies, the most productive is the Feminine Sound plural as it is the default plural form in most loanwords. Unlike prior studies, this study found two new pluralization processes, adopting the English plural and adding the plural suffix -a:t to the English plural of the loan term. Recommendations for further studies that investigate other types of morphological borrowing in Arabic are given.
IMPACT OF URBAN PLANNING RESTRICTIONS ON THE USE OF UNDERGROUND REAL ESTATE
Authors: Nesterenko S. , Radzinska Yu. , Myronenko М. , Afanasiev O.
Published: December 2023

The impact of urban planning restrictions on the use of underground real estate is an urgent contemporary problem that arises from urban development, the need to regulate the process of underground construction, and the broader context of maintaining comfort, safety, ecology, and preserving cultural and historical heritage. Addressing this issue entails finding a delicate balance between the needs of urban planning and the requirements for safeguarding various aspects of urban development.
The article aims to study the manifestations of the influence of urban planning factors on the use of underground real estate.
Urban planning restrictions constitute an essential component of any developed city, as they contribute to a structured and functional environment for residents and businesses. However, these restrictions can significantly affect the use of underground real estate. In this article, we consider what important aspects urban planning policy encompasses and how it influences underground space utilisation.
The paper analyses different approaches to investigating the problems related to underground real estate usage and categorises the various types of urban planning restrictions that bear on such utilisation.
Effective urban development requires an integrated approach and discussion of urban planning constraints that consider the interests of all parties: development, environment, and cultural heritage. Maintaining the right balance between the growth and preservation of values is becoming a crucial objective for urban planning and regulatory frameworks.
Consequently, the impact of urban planning restrictions on the use of underground real estate requires careful monitoring and regulation within the framework of sustainable urban development. Solving this problem requires scientific research, effective interaction of all stakeholders, and the development of urban planning policies that account for various aspects of urban development and underground real estate.
Based on our research findings, we provide a comprehensive overview of the possibilities of optimising the location of underground real estate objects, taking into account current urban planning trends. We also assess the prospects for utilising underground space in the modern structure of settlements.

ANALYSIS OF METHODS FOR ASSESSING THE IMPACT OF A COKE PLANT ON THE ENVIRONMENT
Authors: Galkina O. , Kunytskyi S. , Ivanchuk N. , Tkachov V. , Kunytskyi M.
Published: December 2023

This academic paper explores various assessment methods used to evaluate the environmental impact of industrial enterprises, specifically focusing on coke plants. The study emphasises the widespread use of a global risk-based approach for assessing the environmental risks posed by such enterprises to both the environment and public health. This approach involves predicting potential future environmental consequences under different scenarios, with the choice of a specific method dependent on the particular conditions, objectives, and available resources.The analysis of these assessment methods reveals the prevalence of an integrated approach, which comprehensively evaluates multiple aspects of an industrial enterprise’s environmental impact. Moreover, the research underscores the importance of adopting modern technologies and strategies to enhance water supply and wastewater management efficiency for environmental preservation.The assessment of the ‘Kharkiv Coke Plant’ indicates minimal impact on land inundation issues, with little effect on groundwater quality. However, the excessive consumption of freshwater remains a significant concern, necessitating improved efficiency in the operation of the plant’s wastewater recycling systems. To evaluate the enterprise’s influence on surface waters, notably the Lopan and Udy rivers, the paper calculates the volume and flow of wastewater originating from the facility’s premises.Additionally, environmental impact assessment is conducted using key environmental indicators, including the alarm index, hazard index, and priority index. In light of the identified environmental challenges at the investigated industrial facility, including wastewater discharge into the municipal sewerage system, high water consumption, and phenol emissions from the quenching tower, the paper proposes a solution. This solution entails enhancing the plant’s water recycling infrastructure through the implementation of a closed-loop water recycling system and improving the efficiency of the biochemical plant. This approach aims to mitigate the environmental impact of the enterprise while promoting sustainable water management practices.

MODELS OF EXTINGUISHING AGENT MOVEMENT IN AIR SPACE
Authors: Abramov Yu. , Kolomiiets V. , Sobyna V.
Published: December 2023

A system of linear differentiated equations, which takes into account the resistance of the air medium and the presence of wind, is used to formalise the movement of an extinguishing agent. Furthermore, using the integral Laplace transform allows the construction of a structural and dynamic scheme that reflects the process of supplying an extinguishing agent to the fire. Such a structural and dynamic scheme opens up opportunities for building a simulation model of the extinguishing agent movement using the Simulink mathematical visual modelling package. This simulation model provides for the determination of the current coordinates of the extinguishing agent and the speed of its movement to the fire. The parameters of this simulation model are the initial velocity of the extinguishing agent, the height from which it is supplied, the resistance of the air environment, the angle of supply of the extinguishing agent, and the presence of wind.
We used the Simulink package to simulate the process of the extinguishing agent supply to the fire. Data sets were obtained for the time of the extinguishing agent supply to the maximum range, for the maximum supply range, and for the value of the extinguishing agent velocity at the maximum range. We have noted that for small angles of the extinguishing agent, there is a slight increase in the time of its supply to the maximum range by no more than 3.0% with a threefold increase in the resistance of the air medium and regardless of the variation in the value of the initial speed of the extinguishing agent supply. The analytical dependence of the time of supplying an extinguishing agent to the maximum range on the rate of its supply is obtained. In particular, the time of the extinguishing agent supply to the maximum range at small angles lies within (0.66÷0.88) s, which is quite significant for low-inertial fire extinguishing systems, the inertial properties of which are characterised by time parameters. This circumstance necessitates considering the time of supplying an extinguishing agent to the fire when solving problems of analysis and synthesis of fire extinguishing systems. This factor can be accounted for through the transfer function of the lagging link. The time parameter of such a transfer function is equivalent to the time of supplying the extinguishing agent to the fire.

METHOD OF EXPERIMENTAL RESEARCH OF EVACUATION OF MIXED FLOWS OF PEOPLE OF DIFFERENT MOBILITY GROUPS
Authors: Dotsenko O.
Published: December 2023

The article analyses the current state of research on the evacuation of a mixed flow of people with the presence of persons of different mobility groups (M1, M3, and M4) as part of mixed evacuation flows.
A methodology project was developed, and experimental studies were conducted on the evacuation of a mixed flow of people with the presence of persons of different mobility groups to determine the parameters of their movement, including the density of the human flow, the time of following, the delay time at the door, and the average speed of the participants of the experiment, with the subsequent calculation of the evacuation time. The methodology provides for the simulation of various options for evacuating people during a fire in a separate part of the building.
The article considers options for possible formations of human flows during evacuation when multiple M3 and M4 mobility groups are present, each with different percentage distributions. The obtained data were entered into the empirical database sorted into variational series based on increasing density. For each interval, the mathematical expectation was calculated, representing the arithmetic mean value for normal data distribution. The indicated results will make it possible to create empirical tabular data on the movement parameters of mixed evacuation flows. This data allows for the establishment of the dependence between the movement speed of the evacuation participants and the flow density. Addressing this scientific problem will facilitate the derivation of the dependence of the average value of the speed of the free movement of the flow of people (V0) and the density of the flow (D0), after reaching which an increase in density leads to a decrease in speed, on the quantitative composition of participants in the movement of mobility groups M1, M3, M4 and the coefficient of adaptation of the human flow to changes in its density during movement with different percentages of participants of mobility groups M1, M3, and M4.

Published: December 2023

It has been analysed that wildfires are the most influential factor in environmental pollution. The ecological consequences of wildfires consist primarily of atmospheric air pollution with carbon monoxide, products of combustion of combustible materials, and the burning of oxygen. Plant combustion also contributes significantly to planetary environmental changes: climate warming, ozone depletion, acid rain, chemical and radioactive pollution of the atmosphere, water, and soil. With wildfires, soot particles, that is, carbon and products of incomplete combustion of wood, enter the air.
Smoke, which is formed during fires, explosions, ignitions, etc., during the combustion of plant biomass (grasses, leaves from trees and shrubs, mosses, lichens, peatlands, forest litter and needles), is an aerosol-gas mixture containing hazardous substances dangerous to the environment and humans. Biomass burning is a global source of gas and dust pollution of the atmosphere and is considered one of the determining factors of ecotoxicological risks for public health. The negative impact of fires from military actions on the human body is acute and delayed. Acute exposure leads to hypoxia due to carbon oxides, increased consumption of oxygen from the air during combustion, irritation of the respiratory tract, and difficulty breathing. Delayed exposure is due to toxic, mutagenic, and carcinogenic effects.
The toxic impact of fires on the life and health of the population is not only a threat to life but also an adverse effect on human organisms of heavy compounds of chemical substances represented by the combustion products of plant biomass of forests, peatlands, vast agricultural lands, including crop rotations and pastures. Often, this impact occurs in combination with typical atmospheric air pollution: emissions from industrial enterprises and motor vehicles. The peculiarity of such a combination is the complex synergistic effects of chemical compounds and high air temperature with significant relative duration (decades, months) of emergency environmental situations.

Based on existing developments in ecology, labour protection, ergonomics, and life safety, a definition of the concept of workplace eco-friendliness is proposed. A method for assessing workplace eco-friendliness was developed, which is based on an adapted version of the Fine-Kinney method.
Keywords: eco-friendliness, workplace, safety, employee, Fine-Kinney method.
METHODOLOGY FOR DETERMINING AN EFFECTIVE VARIANT OF WAREHOUSE OPERATION TECHNOLOGY WHEN USING HIGHLY MANOEUVRABLE AND ENERGY-EFFICIENT MULTI-AXLE VEHICLES
Authors: Pavlenko O. , Kalinichenko O.
Published: December 2023

The article establishes that warehousing operations required in the cargo delivery system can take up a significant amount of time and affect the quality of performed work. An analysis of the situation in the warehouse real estate market has shown that there are prospects for the construction and development of existing warehouses through the introduction of new technologies and solutions to improve technical means of production. Therefore, for the rational operation of the entire complex of warehouse operations and the corresponding increase in productivity with a reduction in the cost of delivery of goods in existing warehouses with intensive flows of goods, it is necessary to introduce an efficient warehouse technology using highly manoeuvrable and energy-efficient multi-axle vehicles. The article analyses the scientific developments of the theoretical foundations for determining an effective variant of warehouse technology by Ukrainian and foreign scientists. The work on improving the technology of warehouses and terminals focuses on the development of effective interaction in all areas of warehouse operations under the influence of random factors. The analysis of the technology of warehouses operating in the Ukrainian market has revealed shortcomings in its organisation: possible options for performing basic warehouse operations when changing the values of technological process parameters are not taken into account, warehouse resources are not used effectively to perform the relevant operations, and opportunities for introducing new technologies into the warehouse technology are not taken advantage of. It is proposed to determine an effective variant of the warehouse operation technology when using highly manoeuvrable and energy-efficient multi-axle vehicles to consider this process in the form of two variants of their organisation with the participation of an electric forklift (first variant) and the proposed mechanism (second variant). To form these variants, the sequence of warehouse operation technology, technical characteristics of mechanisation equipment, and a schematic representation of a warehouse with racks have been determined. The total area of the warehouse was chosen as the objective function of solving the problem of determining an effective variant of warehouse technology when using highly manoeuvrable and energy-efficient multi-axle vehicles, taking into account the system of constraints. The system of constraints includes the relevant factors of influence: the volume of a unit of cargo that passes through the warehouse; time to perform operations when loading (unloading) cargo in the warehouse; time to perform operations when moving cargo by a forklift in the warehouse; loading of a unit of cargo on the warehouse area.

CULINARY ETHNOLOGY OF PODILLIA: FEATURES AND RECIPE INGREDIENTS
Authors: Bazhenova S. , Khoptiar A.
Published: December 2023

The article considers the actual and unique issue of studying the traditional recipes of Podillia to identify their uniqueness and regional features. We determined that this issue’s regional and local lore aspect opens vast opportunities for its use as a historical source. Patterns of the presence or absence of particular themes and motives often find their reasons in historical factors. To some extent, this also applies to such an area as the country’s cuisine and culinary traditions. The study revealed that the functioning of folk customs is subordinated to more practical than aesthetic requests. Where the question of folk traditions, beliefs, customs and rites, life and lifestyle of the population arises, only there is a prerequisite for the appearance of authentic cuisine and original recipes. Thus, the etiology of such folk recipes lags far behind the customs etiology in time. The previous research has proven that the identified features of the development of Ukrainian cuisine relate specifically to the national culinary traditions and customs of the population of Podillia. This layer of folk culture needs urgent exploration. A detailed study of the peculiarities of cuisine and culinary traditions can give ethnographers and culturologists valuable information about our people’s history, ancient traditions, beliefs, and culture. The specificity of the researched object and the degree of study of the chosen topic determined the purpose of the article, which is studying and organising the characteristic features of the culinary heritage of Podillia, as well as collecting and registering authentic recipes and methods of cooking dishes that reflect the cultural heritage of this region of Ukraine. The practical significance of the obtained results is that its main provisions can be used by specialists in various fields: ethnographers, folklorists, culturologists, historians, geographers, and tourism specialists. The personal contribution of the authors consists of the systematisation of folk culinary traditions and folk recipes of Podillia and a comprehensive study of the genealogy of ethnic cuisine.
Keywords: Podillia, Ukrainian cuisine, culinary ethnology, culinary heritage, folk recipes, cooking technology.

Facing the War in Ukraine: The Subjective Perspective of Social Assistance Beneficiaries
Authors: Szczygieł Oskar , Zwęglińska-Gałecka Dominika
Published: December 2023

W niniejszym opracowaniu koncentrujemy się na beneficjentach pomocy społecznej
i ich reakcjach na sytuację zagrożenia i niepewności wywołaną wybuchem
wojny w Ukrainie oraz przybyciem uchodźców wojennych do Polski. W analizie
wykorzystano wyniki badania ankietowego przeprowadzonego na reprezentatywnej
próbie 1057 beneficjentów pomocy społecznej w województwie mazowieckim.
Najwięcej respondentów przewiduje, że na skutek wojny w Ukrainie zwiększy się
poziom ubóstwa gospodarstw domowych, pogorszy się sytuacja gospodarcza w Polsce,
a także ich własna sytuacja finansowa. Beneficjenci spodziewają się spadku
dochodów budżetu państwa, a także dochodów swoich gospodarstw domowych.
Nasze analizy, choć stanowią fragmentaryczny obraz rzeczywistości beneficjentów
pomocy społecznej w województwie mazowieckim, ukazują, że to właśnie w licznym
napływie uchodźców z Ukrainy beneficjenci pomocy społecznej widzą największe
zagrożenie dla sytuacji materialnej zarówno w kraju, jak i poszczególnych
jednostek. Może to rodzić napięcia na linii Polacy–Ukraińcy, dlatego tym ważniejsze
powinny być rekomendacje ukierunkowane na przeciwdziałanie dyskryminacji
i szerzeniu się antyuchodźczych postaw i narracji w polskim społeczeństwie.
Ідентичність українця в умовах війни: особливості переживання загроз
Authors: Вінков Веніамін
Published: December 2023

Актуальність дослідження зумовлена воєнною агресією з боку Російської Федерації, що призвело до втрати значної частини української території, жертв серед мирного населення і військових, руйнування міст, еміграції за кордон і переміщення громадян усередині країни. Відповідно, у таких умовах ідентичність громадян України зазнала певних змін і потребує ґрунтовного вивчення.

Метою наукового дослідження було емпірично дослідити, як залежно від проявів ідентичності громадян України відбувається переживання ними загроз і як змінюється в умовах небезпеки їхня поведінка.

Методологія. Інструментарій дослідження охоплював онлайн-опитування, семантичний диференціал; частотний аналіз, кореляційний аналіз за критерієм Спірмена, інтерпретацію та узагальнення результатів емпіричного дослідження.

Основні результати. Виявлено найбільш поширені серед українців прояви ідентичності. Перші два варіанти ідентичності відображають державницьку позицію: один із них пов’язаний з належністю до європейської, громадянської та професійної спільнот, а другий – до місцевої, громадянської та професійної спільнот. Респонденти з такими варіантами ідентичності вбачають найбільшу загрозу з боку росіян, тоді як з боку української влади та суспільства такої загрози, на їхню думку, немає. Два інших варіанти можуть становити загрозу для цілісності Української держави: одна з ідентичностей пов’язана з вибором місцевої і східнослов’янської спільнот, а друга – східнослов’янської і релігійної. Респонденти з останнім варіантом ідентичності не бачать загрози з боку росіян, а вбачають її в українській владі і суспільстві.

Перспективи подальших досліджень. Урахування особливостей самовизначення громадян дасть змогу більш ефективно проводити інформаційну політику протидії ворожій пропаганді, маніпулюванню громадською думкою та впроваджувати різні програми щодо зміцнення інституту громадянства та демократії в Українській державі.
Динаміка соціально- та політико-психологічних особливостей вітчизняної молоді протягом російсько-української війни
Authors: Drozdov Oleksandr
Published: December 2023

Актуальність дослідження зумовлена недостатнім рівнем вивчення зміни низки соціально- та політико-психологічних характеристик вітчизняної молоді, що відбулися протягом широкомасштабної російської агресії в Україні. Мета статті полягає у вивченні динаміки показників суб’єктивного благополуччя, патріотизму, колективного нарцисизму, а також ставлення до представників різних етномовних спільнот серед вітчизняної молоді після початку широкомасштабної російсько-української війни. Метод і методологія. Шляхом онлайн-опитування досліджено 1372 студенти з різних регіонів України (Центр, Північ, Південь, Захід, Схід). Дослідження проводилося в три етапи: у 2021, 2022 (до початку російського вторгнення) і 2023 роках. Досліджуваним пропонувалися: шкала суб’єктивного благополуччя Е. Діннера (SWLS), шкала колективного нарцисизму (CNS), шкала патріотизму з опитувальника «Громадянська ідентичність» І. Петровської, шкала соціальної дистанції Е. Богардуса, авторська анкета. Основні результати і висновки. Події широкомасштабної війни значною мірою вплинули на соціально- та політико-психологічні особливості вітчизняної молоді. Зокрема, знизилися показники суб’єктивного благополуччя, зріс рівень патріотичних настановлень, а також пов’язаного з ними колективного нарцисизму (що може бути передумовою для майбутніх соціальних проблем). Війна стимулювала процеси аутгрупової дискримінації та інгрупового фаворитизму, які зачепили не лише представників ворожих країн, а й громадян власної країни, що належать до етномовних меншин. Вираженість більшості з вищеописаних тенденцій опосередкована такими соціодемографічними змінними, як регіон проживання, стать, мова спілкування. Усі виявлені зміни можна вважати статистично достовірними. Перспективи подальших досліджень пов’язані з подальшим моніторингом динаміки соціально-психологічних характеристик молоді, особливостей її політичної свідомості (і в період військових дій, і по його закінченні). Цікавим також може бути вивчення ставлення до війни, настановлень щодо соціального домінування та низки інших політико-психологічних показників.
