The article comprise issues related to the development of floorball in Ukraine and Volyn. The purpose of the study: to investigate the historical aspects of floorball development in Ukraine and Volyn. Materials and methods of research. The study was conducted by a group of teachers of Lesya Ukrainka Volyn National University and Lutsk National Technical University from September 2021 to March 2022. Theoretical analysis and generalization of scientific and methodological data have been used. Results of the research. Floorball has been developing in Ukraine since the 2000s. The first efforts to create the floorball federation dates back to 2005. Public Association "Ukrainian Floorball Federation" was established on October 22, 2016. The federation is based on the club system. The UFF consists of 33 clubs. UFF is a member of the International Floorball Federation. The beginning of floorball development in Volyn is connected with the formation of the Wild-West team which was set up in schools 25, Lutsk. It was not the first team in the city , since previously there was a floorball club in 2008 that was based on the youth organization YMCA. This team hasn’t existed for a long time due to the lack of motivaion and development. Thanks to the hard work of Wild-West team leaders and responsible attitude, they have become a club that has grown and developed , namely functions properly to this day Conclusions. Floorball in Ukraine has demonstrated a high speed of popularization and systemic development. The democratic management scheme has added life to the UFF, and pointed to the real influence of clubs on the development of floorball in Ukraine. At various stages, there are problems that hinder the speed of development of this type of game, but usually the problems are not critical or unresolved. These are the things that will definitely make floorball in Ukraine and Volyn a stronger sport and over time they will have a positive impact on the development of floorball in the world.

In each time within Indonesia history, the press has its own interesting story to study, especially in the post-New Order or the reformation era where the press was considered free in reporting all information, and even tended to be excessive. It is interesting to see how historians respond to the press at this time as part of the contemporary historiography in Indonesia.
Pendidikan Islam dan Pengaruhnya Terhadap Keber-agamaan di Minangkabau
Authors: Alfurqan
Published: June 2022

Dalam dinamika keagamaan di Minangkabau telah terjadi beberapa gelombang arus pembaharuan di Minangkabau, hal ini disebabkan oleh pengaruh Pendidikan yang diterima oleh ulama dan masyarakat di Minangkabau. Seluruh ulama yang terlahir di Minangkabau adalah hasil dari didikan surau, namun karena keilmuan Islam bersumber dari Timur Tengah, oleh sebab itu banyak dari ulama Minangkabau yang mematangkan pendidikan Islam di Timur Tengah. Timur Tengah yang saat itu menjadi pusaran perpaduan kultur budaya dan pemikiran reformis dalam Islam, sehingga hal ini mempengaruhi sebagian pelajar dari Minangkabau yang kemudian dikenal dengan kelompok modernis (kaum muda), dan pelajar yang masih terbentengi dari pengaruh tersebut dan masih berpegang kokoh dengan pendidikan surau dan pemikirannya dianggap sebagai kaum tradisional (kaum tua). Pengaruh dari kedua kelompok ulama ini melahirkan dinamika kebereagamaan di Minangkabau dan keragaman praktek keagamaan beserta polemik-polemik di awal abad ke-20.

Authors: González-Sánchez Marcos
Published: June 2022

Los ministros de culto realizan funciones con relevancia civil y algunos de sus actos religiosos tienen efectos civiles. Hay confesiones religiosas que no restringen el estatuto de los ministros a los varones. Dado que las normas de Derecho Eclesiástico que aluden indirectamente a las mujeres ministros de culto son escasísimas (Seguridad Social), en este trabajo queremos acercarnos a esa realidad y conocer el número de mujeres que realizan funciones religiosas con efectos civiles. Para la obtención de estos datos, hemos consultado a la Subdirección General de Libertad Religiosa el número de los ministros de culto anotados en el Registro de Entidades Religiosas, y a las confesiones religiosas cuántas son mujeres. Asimismo, este análisis permitirá saber más de las funciones que desempeñan las mujeres en las confesiones.

Introduction. Polymer composite materials (PCM) are used to improve the mechanical properties and increase the working period of products. For the processing of products made of PCM, the use of electrophysical processing methods is standard. One of these methods is copy-piercing electrical discharge machining (EDM). The use of such methods for processing PCM is due to its high physical and mechanical characteristics and the complexity of processing by blade methods. Considering the fact that the PCM element is a binder – epoxy resin, which is destroyed at the edges of the resulting holes and grooves during EDM, PCM can be considered difficult to process. During the EDM of holes in PCM products, the temperature rises, and inefficient cooling often occurs in the processing zone. The paper is devoted to theoretical simulation in the Ansys package, which makes it possible to evaluate the impact of flushing method on the efficiency of the EDM of PCM products based on numerical simulation in finite element analysis software systems. The aim of the work is to increase the productivity of the processes of EDM for PCM products. Methods. Experimental studies were carried out according to the method of a classical experiment on a copy-piercing electrical discharge Smart CNC machine. The workpiece was processed at a constant voltage U = 50 V, pulse on-time Ton = 100 µs and current: I = 10 A. For theoretical simulation of the flow, the ANSYS CFX 20.1 software was used. Flow distribution simulation was carried out at three processing depths (2 mm, 10 mm, 15 mm), as well as at three nozzle inclination angles (15°, 45°, 75°). Results And Discussion. The analysis of the data obtained showed that in the case of the EDM of PCM, the angle of the location of the flushing nozzles should be taken into account in order to increase the productivity of processing deep, blind holes. It is established that the highest performance value is achieved when the nozzles are located at an angle of 15˚. The laminar motion prevails. With this arrangement of the nozzles, the value of the liquid pressure and the removal of the sludge are stable both with the EDM of PCM to a depth of 2 mm, and when processing to a depth of 15 mm. It is noted that for processing holes with a depth of 10 mm or more, it is worth considering the angle of inclination of the flushing nozzle for effective processing, it is necessary to remove eroded particles from the gap. In the process of conducting an experimental study, when processing holes with a depth of 15 mm, sticking of sludge to the electrode-tool was observed, as well as the closure of the EDM process, the occurrence of secondary discharges in the processing zone, which caused the processing to stop.

Introduction. Boriding and aluminizing are among the effective methods for improving the performance properties (corrosion resistance, heat resistance and wear resistance) of machine parts and tools. Solid-phase methods of carrying out techniques of thermochemical treatment (TCT) require long-term exposure at elevated temperatures, which negatively affects the structure and properties of the base material. From these positions, the selection of reasonable temperature-time parameters of solid-phase boriding and aluminizing processes is an urgent task. The purpose of this work is to assess the effect of low-temperature boriding and aluminizing processes on the structure and microhardness of diffusion layers on the surface of low-carbon steels. The paper considers two grades of steels with a carbon content of up to 0.4%: low-carbon steel St3 and alloy steel 3Cr2W8V. The use of the second steel is due to the need to identify the effect of alloying elements in steel on the thickness of diffusion layers and its composition. Powder mixtures based on boron carbide and aluminum carbide are selected as sources of boron and aluminum. Results and discussions. It is found at a process temperature of 900 °C and holding for 2 hours after boriding, iron borides are formed on the surface of both steels. At the same time, two borides FeB and Fe2B are detected on St3 steel by X-ray phase analysis (XRD), and only the Fe2B phase is detected on 3Cr2W8V steel. After aluminizing, aluminum-containing phases such as Al5Fe2, Na3AlF6 and Al2O3 are formed in both steels. The thickness of the resulting diffusion layer on St3 after boriding is 35 μm, after aluminizing – 65 μm. The thickness of the diffusion layer on 3Cr2W8V steel is equal to 15 μm after boriding and 50 μm after aluminizing, which is significantly less than on carbon steel and is obviously due to the effect of alloying elements. It is established that TCT leads to a significant increase in the microhardness of the samples surface. Thus, the maximum microhardness of St3 steel increased to 2,000 HV, and the maximum microhardness of 3Cr2W8V steel increased to 1,700 HV after boriding. The microhardness after aluminizing is comparable for both steels and is equal to 1,000-1,100 HV. Elemental analysis of the upper sections of the diffusion layers shows that the content of boron (7-9%) and aluminum (50-53%) corresponds to the detected XRD iron borides and aluminides. In all cases, there is a gradual decrease in the diffusing elements in the direction from the surface to the base.
A nagy lejtő. A fejlett és fejletlen kisrégiók tanulói teljesítménykülönbségeinek növekedése
Authors: Polónyi István
Published: June 2022

A tanulmány célja. hogy az oktatási/tanulási teljesítmény területi összefüggéseit vizsgála a hazai oktatási rendszerben. A kutatási kérdés az, hogy a járások fejlettsége kapcsolatot mutat-e a közoktatási kompetencia eredményekkel illetve a felsőoktatásba felvetteknek a felvételin elért összpontszámával. A hipotézis azt feltételei, hogy az oktatási/tanulási teljesítmény annál jobb, minél magasabb a járás fejlettsége. Tehát az oktatási/tanulási eredmények lejtenek a fejlett járásoktól a fejletlenebbek felé.  
Az írás által bemutatott elemzés a kompetenciavizsgálatok eredményeinek területi alakulást vizsgálva arra a megállapításra jutott, hogy mind a szövegértés, mind a matematika eredmények járási átlaga szorosan együttjár a járások komplex fejlettségi mutatójával. Az együttjárás jelentős lejtést mutat: a fejlettebb járásokban élő fiatalok eredményei jobbak mint a gyengébb fejlettségű járásokban élőké. Ráadásul a lejtés meredeksége az évfolyamokon felfelé haladva növekszik. Más oldalról az is elég világosan látszik, hogy ez a lejtés az elmúlt fél évtized alatt növekedett. Ez a nagy lejtő a felsőoktatási felvételin elért pontszámok esetében is szembetűnő, és itt is a növekedett a lejtő meredeksége az elmúlt fél évtizedben.
A tanulmány azzal zárul, hogy rámutat arra, hogy az eredmények tanulságait fontos lenne az oktatáspolitikának levonni, ezek ugyanis arról tanúskodnak, hogy az elmúlt időszak oktatáspolitikája nem volt képes kezelni az oktatási rendszer területi különbségeit, olyannyira nem, hogy azok növekedtek.

Jelen tanulmány a Balaton-felvidéki nyaralókba, második otthonokba történő urbánus középosztályi – a COVID-19 pandémia idején felerősödött – beáramlás társadalmi, gazdasági következményeit, dzsentrifikációs hatásait, illetve a lehetséges válaszokat vizsgálja. A világjárvány egyrészt felerősítette, másrészt új mederbe terelte a vidék átalakulási folyamatait. A vidéki turizmus a járványhelyzet miatt először leállt, azután hihetetlen mértékben felpörgött. Ugyanakkor a pandémia nyomán kiszélesedő távmunka illetve távoktatás alapvetően változtatta meg a vidékhez való viszonyt, sokan ’leköltöztek’ az eddig csak nyaralóként használt ingatlanokba. A Balaton környéki ingatlanárak meredeken emelkednek, a beköltözők mellett megjelentek a befektetők és a „hideg pénz” is, ami egyértelműen dzsentrifikációs átalakulásról tanúskodik.
Tanulmányunk félig strukturált interjúk és egy kérdőíves megkérdezés segítségével tárja fel, hogy hogyan alakult a vidéki turizmus a járvány különböző szakaszaiban a Balaton-felvidéken, hogyan változott a nyaralótulajdonosok attitűdje és gyakorlata a vidékre költözéssel kapcsolatban, illetve melyek voltak a változás fő előidéző okai és tényezői és milyen változásokat hozott mindez a társadalmi, gazdasági környezetben, a helyi fejlesztési lehetőségekben. A kutatás eredményei szerint a pandémia felerősítette a korábbi tendenciákat, vagyis a vidéki élettér iránti kereslet növekedését. A jövőbeni szándékok a vidékre költözés tekintetében mérsékeltebbek, ennek hátterében a szolgáltatások kínálata és minősége is szerepet játszik.

Published: June 2022

Apricot flower midge (Contarinia pruniflorum Coutin & Rambier Diptera: Cecidomyiidae) was first detected in Prunus species in the 1950s and did not become a significant pest for a long time. However, towards the 2000s, the pest caused damage to apricot and plum especially in Mediterranean countries and its distribution continued to increase. The population density of the pest is closely related to the climate of the agricultural area. In recent years, the fluctuation in climatic data causes the population fluctuations. The study was carried out in the Kale and the Yeşilyurt district of Malatya province (Turkey) in 2017-2018. Some biological stages of apricot flower midge were determined in Malatya province and these data were interpreted together with climatic data. It was determined that the pest overwinters as a pupa in the soil. In February, the adult emerges from the pupa with the warming of the air and soil temperatures. It was determined that the adult emerged from the pupa when the soil temperature was 13-14 °C and the air temperature was 7-15 °C. At the beginning of the pink-bud stage of apricot, the pests lay eggs into flower buds. The larval development is approximately 25-28 days. The average number of larvae in the damaged buds was 14, the maximum number of larvae in a bud was 26, and the pest gave an offspring annually and the ratio of male to female was 0.08.

Published: June 2022

Youth internal migration is seen as a solution to youth unemployment, and this has resulted in over urbanization and its associated negative effects such as congestion, pollution, unemployment, underemployment, and increased crime rates. The study aimed at examining the employment status of youth migrants, assessing the relationship between demographic factors and youth internal migration, investigating the association between socio-economic factors and youth internal migration, and evaluating the association between reasons for migration and migrant employment status. The study used secondary data collected in the youth employment and migration in Eastern and Southern Africa project. In Uganda, the project was carried out in nine districts. The study focused on both men and women aged 18-35 years and a total number of 1524 respondents were interviewed. Results of the study revealed that age, residence, and region had a significant association with migration status (p≤0.05). Age, sex, number of children, region, and reasons for migration had a significant association with self-employment status of the migrant (p<0.05). Marital status, sex, and reasons for migration had an association with the possibility of a migrant youth being employed (p≤0.05). The study recommends that local governments should provide the required infrastructures, social services, and amenities to encourage youths to carry out economic activities so as to develop their places of origin.

Published: June 2022

Many women in developing countries are dying from preventable causes related to pregnancy and childbirth. These maternal deaths are attributed to the poor coverage of reproductive health services and high fertility levels. A holistic review of the reproductive health is necessary to reflect the country’s situation and progress of reproductive health and provide recommendations for areas that need an improvement. The aim of this paper is to provide an overview of the historic development of maternal mortality and fertility in Myanmar during the past 25 years, focusing on the antenatal care (ANC) coverage, deliveries attended by skilled persons, and contraceptive use. All published nationally representative data were compiled, and trend analysis was performed. The maternal mortality ratio declined significantly by 9.1 (95%CI: 4.0-14.1) maternal deaths per 100,000 live births/year between 1990 and 2015, but it failed to achieve the target of Millennium Development Goals 5. There was no significant improvement in ANC coverage and care during delivery. Contraceptive use increased significantly, leading to a reduction in the total fertility rate. Nevertheless, overall reproductive health failed to reach a satisfactory level. Maternal mortality still remains high. Thus, there is a need to improve service coverage and more so in the regions with poor performance to reduce the high maternal mortality.

This study aimed to compare internet use among African American older adults by gender and age group and investigate correlates of internet use by gender and age group. A total of 1117 African American older adults aged over 50 from the 2016 Wave of the Health Retirement Study were included in the study. Sequential ordinal logistic regressions were conducted to investigate correlates of internet use among older African Americans by gender and age group. Significant gender and age differences were identified in internet use frequency. Gender differences on correlates were revealed: being old-old and limitations on activities of daily living were only associated with decreased odds of more frequent internet use among women. In addition, higher depression was only associated with reduced odds of more frequent internet use among men. Age differences on correlates indicated that education and cognition were the only two significant factors pertinent to internet use among the old-old. By contrast, for young-old adults, retirement, poverty, education, cognition, and depression were also predictive. Practitioners should consider these gender and age differences when promoting internet use among older African Americans. The results presented in this study might also inform the design of future gender- and age-tailored interventions.
Immigration-related stressors and mental health problems among Asian-American Immigrants
Authors: Liu Sizhe , Zhang Wei
Published: June 2022

Focusing on Asian-American immigrants in the National Latino and Asian American Study, this work examines (1) whether immigration-related stressors are associated with 12-month depressive disorder and suicidal ideation, and (2) how individual religious involvement moderates the associations. Findings from regression analyses reveal that limited English proficiency increases the risk of both 12-month depressive disorder and suicidal ideation. No significant differences in 12-month depressive disorder and suicidal ideation are found by age at immigration. Most importantly, religious coping — frequently seeking comfort from religion — buffers the negative effects of limited English proficiency on suicidal ideation. Our findings suggest the importance of individual religious involvement in helping Asian-American immigrants cope with stress associated with immigration. Mental health professionals may need to integrate religious coping mechanisms into the clinical setting to offer more effective treatments that are sensitive to individuals’ religious and spiritual needs.
Evaluation of Covid-19-Associated Hypercoagulability with Functional Coagulation Assays and Extracellular Vesicles
Authors: Spiezia Luca
Published: June 2022

Most patients affected by the novel coronavirus SARS-CoV-2 — responsible for the Coronavirus disease, COVID-19 — remain asymptomatic or develop mild symptoms. Only a small percentage of cases develop a severe disease that may lead to a fatal outcome. Since the early reports published in the literature by Wuhan colleagues, we have learned that patients hospitalized for acute COVID-19 infection have different clinical and laboratory pictures of coagulopathy. In particular, a marked increase in blood clotting capacity has been reported in most hospitalized patients – COVID-19-associated coagulopathy, CAC – which in turn increases the risk of developing thrombotic complications. The main pathophysiological mechanisms underlying this hypercoagulable state are inflammation, endothelial damage, hypofibrinolysis and hypoxemia. Traditional coagulation tests fail to fully characterize the nature and severity of COVID-19-associated hypercoagulability (CAH). Hence the need for functional coagulation assays (i.e. tromboelastometry/graphy, thrombin generation, platelet function test) and circulating extracellular vesicles to better understand these peculiar conditions. Moreover, it would be very helpful to use these tests to identify patients at increased risk of developing thrombotic complications or with a worse prognosis as well as to ascertain the effectiveness of the anticoagulant treatment. The aim of our narrative review was to describe the main pathophysiologic mechanisms of CAH and to summarize the current knowledge on functional coagulation assays and extracellular vesicles tests in CAH.

Authors: Oloyede Iso , Nnoli Chinenye , Akpan Itoro
Published: June 2022

Introduction: Post-covid long-hauler syndrome has been observed in up to half of the children who had symptomatic Covid with symptoms lasting beyond 120 days. Case report: PEC, is an 11year old female who presented with a history of unproductive Cough 5/7, Fever 5/7 and breathing difficulty. Physical examination revealed an acutely ill, dyspneic and tachypneic child, with a respiratory rate of 42 cycles/min. She had vesicular breath sounds and few basal crepitations. Her SPO2 was 75% in room air. The Chest Xray showed widespread nodular opacities. Her manteoux test was 3mm. A chest CT-scan showed diffuse in-homogenous densities with fibrocystic changes seen involving both lungs with associated areas of ground glass opacification in the upper lung bilaterally. Her COVID-19 PCR test was positive. A diagnosis of COVID-19 disease was made. She was admitted into the paediatrics ward and treated with antibiotics and intranasal oxygen. Her SPO2 remained between 85-88% on oxygen and 75-79% in room air. She became stable on the 6th day of admission and parents left against medical advice. Four months post diagnosis the child presented with cough and breathlessness. A repeat chest x-ray showed massive lung infiltrates, multiple patchy opacities and hyperinflated lung fields. Her ESR was 30mm in the first hour. A lung function test was suggestive of severe restrictive/obstructive abnormality. The 2- dimensional echocardiography was normal. A diagnosis of Post-covid 19 interstitial lung disease was made and she was placed low dose prednisolone 2mg/kg for six weeks. Her response to treatment will be assessed in subsequent follow-up. Conclusion: Post COVID long-hauler syndrome is present in children who survive COVID-19. A high index of suspicion is required to diagnose and offer the correct treatment.
Payment for Ecosystem Services in Costa Rica: Evaluation of a Country-wide Program
Authors: Murguia Juan M. , Ordoñez Pablo , Corral Leonardo , Navarrete-Chacón Gilmar
Published: June 2022

Several countries have implemented payment-for-ecosystem-services (PES) programs, buoyed by the promise of these programs as a win-win strategy that would allow both the conservation of natural resources, and the reduction of poverty for rural households and communities. Our study evaluates the effect on deforestation of Costa Rica's PES program, one of the oldest country-wide programs in the world. Costa Rica approved the 1996 Forest Law (Law No. 7575), creating a PES program that compensates landowners for forest conservation. We estimate these effects using an event study design with staggered entry into treatment. Our results show a statistically significant effect for the first year with a decrease in deforestation of 0.21 ha, but not for the following years. Given that the baseline level of deforestation in our sample is low, the magnitude of the effect is large. When compared to the pre-2016 average level of within farm deforestation, our estimated effect would imply a 100% reduction in deforestation for the first year after enrollment. Given the program pays the participants for a 5-year period, and that the effect is significant only during the first year, it may be beneficial for the program to reduce its length and implement required simplified annual contract renewals or other behavioral interventions to reduce noncompliance in subsequent years.

“Peaceful Conquest of Minds and Hearts by the Power of Enlightenment ...”: Activities of the Vilna Department of the “Society of Zealots of Russian Historical Enlightenment in Memory of Emperor Alexander III”
Authors: Krot Maxim
Published: June 2022

The article examines the activities of the Vilna department of the “Society of Zealots of Russian Historical Enlightenment in Memory of Emperor Alexander III”, whose appearance at the turn of the 19—20th centuries was part of a non-conflict management practice aimed at forming a positive symbolic capital of the empire on its northwestern outskirts. In addition to purely scientific activities, this Society was intended to become an element of a public environment controlled by the authorities, whose representatives could relay imperial ideological values, exerting an integrative impact on the local population. The Vilnius branch of the “Society of Zealots ...” was an attempt to combine the traditional imperial policy aimed at comprehensively strengthening the “Russian principles” in the region and the “soft power” strategy aimed at rejecting unilaterally coercive methods of influencing the local population in developing a general imperial spiritual intellectual identity. On the basis of archival materials, first introduced into scientific circulation, the main stages of the existence of the Vilnius Department of the Society, the main forms of its work, the numerous problems facing it, which ultimately did not allow to fully realize the significant cultural and integrative potential of this project, are considered.
Pilgrimage and Operations of the Russian Shipping and Trade Society in the Eastern Mediterranean (Early 1880s)
Authors: Baryshnikov Mikhail
Published: June 2022

Using archival materials, the article analyzes the key role played by the Russian Society of Shipping and Trade (ROPiT) in the transportation of pilgrims in 1880—1882. to the Middle East, to the holy places. The study focuses on the firm's shipping activities and, in particular, on the various diversification strategies it followed. Three drivers of this diversification — government support, good governance and significant investment — contributed to the development of shipping in the Eastern Mediterranean in the early 1880s. The data contained in the article indicates that the company and the Russian government used identical strategies during the period under review in their attempts to meet the needs of pilgrims in the Middle East. This allowed ROPiT to successfully overcome the contradictions between public expectations and the need to maintain the entrepreneurial orientation of transport activities. The results of the study show a close connection between geopolitical, sociocultural and economic interests and contribute to further discussion of the relationship between business, government and religious movements during large-scale historical changes in the Eastern Mediterranean region.
Post-Soviet Space in Russian-American Relations (First Quarter of the 21st Century)
Authors: Kosau Alexandr
Published: June 2022

This publication examines the policy of Russia and the United States in the post-Soviet space in the first two decades of the 21st century. The materials were information sources on the foreign policy of the two countries, as well as research by Russian and Western authors using general scientific and special historical methods. The purpose of the article is to examine the role and place of the post-Soviet space in Russian-American relations in the 21st century. In the 21st century, the post-Soviet space has become an arena of geopolitical rivalry between Russia and the United States. This happened due to the cardinal divergence of the national interests of Moscow and Washington in the region. The United States decided to reformat the post-Soviet space, finally ousting the Russian Federation with the prospect of changing the political regime in Russia itself. The realization of this fact by the Kremlin has led to the strengthening, to the best of its ability, of Russian opposition to American penetration into the region. Consequently, in the 21st century, the post-Soviet space has become one of the irritants of Russian-American relations.
The Border Defense Systems of Sasanian Iran
Authors: Dmitriev Vladimir
Published: June 2022

Almost all the great ancient both Eastern and Western powers sought to secure their borders by erecting border defensive lines. In this respect, Sassanian Iran was no exception. On the borders of the Sassanid Empire at different times, but mainly during the period of the highest power of the Sasanid kingdom (4th—6th centuries CE), strong fortification systems were erected. In scale, they surpassed many of the more famous similar structures created in the Classical world. These included the Wall of the Arabs, the Wall of Gorgan, the Wall of Tammishe, Jar-i Kulbad, the Darband fortification system, and the Darial Gorge.
Problems of European Solidarity: Baltic States in the Context of the Migration Crisis
Authors: Antonova Lidia
Published: June 2022

At the beginning of the 21st century, the solidarity of the member states of the European Union is under unprecedented pressure. The migration crisis of 2014—2016 was one of the main reasons of that. The Baltic region took a special place during the crisis. This region is a combination of states with two models of approaches to the implementation of the refugee admission policy — from full implementation to complete rejection of admission. This article analyzes the content of the activities of the EU border states governments in the Baltic region, through which the migration flow has passed, and its correlation with the official position of Brussels. Special attention is paid to the public opinion and social cohesion in relation to incoming refugee flows.
