The events of February 2022, related to the military aggression of the Russian Federation and a full-scale attack on Ukraine, became the greatest catastrophe of the twenty-first century and the most brutal war on European soil since the Second World War, and is gradually being defined as World War III in terms of its impact on global political and economic relations and the use of military weapons. Although no final assessment has been made (the war is ongoing), the undeniable consequence of Russian aggression has been the violation of the world order built after World War II and the risk of global chaos. One of the most powerful consequences of the war was an unprecedented wave of Ukrainian migration, the lion's share of which was to Europe. And while European countries, faced with an unprecedented influx of refugees, are withstanding the socio-economic burden with dignity, Ukraine has found itself in a demographic catastrophe. The wave of forced migration coincided with long-term demographic problems: a decline in the birth rate, an increase in the number of middle-aged people, and the outflow of population during the war. All these processes will have a steady impact on global migration and political processes. New instruments of state and global regulation of these processes will be required. They will also require the formation of a new paradigm of global economic development. The authors aim to deepen the study of the issue of identifying and assessing the preconditions and consequences of migration processes in the world under the influence of military operations in Ukraine. The paper examines the impact of migration processes on globalisation and economic processes in Europe and the world; the dynamics of the share of labour migrants in the total labour force by income level of destination countries in 2013, 2017, 2020; features of the migration wave of Ukrainians evacuated due to the military aggression of the Russian Federation in 2022; generalised statistical information on the migration processes of Ukrainians during the period of 01.02.2023 – 21.06.2023; detailed statistical data on the number of Ukrainian citizens abroad (as of 01.02.2023), broken down by migrant countries; political and socio-cultural context of the formation of a new paradigm of migration processes. The full implications for Ukrainian migration will be summarised after the war is over, but the following interim conclusions are relevant today. The analysis of migration processes in the world and Europe in the current context suggests that migration is actively taking place and contributes to the development of international integration, as it reduces the number of barriers and increases opportunities. The war in Ukraine will have a significant impact on the economy in terms of the following effects: disruption of global supply chains, increased inflationary pressures, higher energy and raw material prices; food prices will also increase as supplies of wheat and cereals from the Russian Federation and Ukraine are disrupted. and Ukraine have been disrupted; higher energy and commodity prices will cause further inflation, deteriorating economic prospects, reduced confidence and increased financial market risk associated with greater geopolitical tensions; worsening food security in some developing countries in the Middle East and Africa. On the other hand, migration is currently seen as a tool for long-term growth in the EU. The analysis shows that migration provides significant economic benefits, primarily to host countries. Today, the EU is facing a growing shortage of skilled labour due to unfavourable demographic trends in Europe. Given the massive emigration of Ukrainian citizens to the EU, migrants are solving the problem of staff shortages. This is especially true given that Ukrainian emigration provides for adequate social protection and legal support, which guarantees the right to settlement, work and education. The right to employment is readily exercised by Ukrainian migrants, as they are largely people of working age, primarily women. In general, it can be argued that the prospects for regional migration are currently linked to many factors and very uncertain prospects for a return to the pre-2022 or pre-pandemic models of the Eastern Partnership. The war in Ukraine is already escalating into a protracted conflict that will threaten both the economic situation of millions of people and the hopes of temporarily displaced Ukrainians to return home for a long time. As a result, displaced Ukrainians, their host EU countries, and the Ukrainian government will have to deal with the new circumstances, adapting temporary modalities to longer-term solutions.

Human settlements are an outcome of people occupying land. In the 1940s and 1950s, a pivotal era unfolded in the demographic landscape of Kazakhstani lands. This period was shaped by the policies of the Soviet government, particularly during the Second World War, which saw the mass deportation of various Soviet people, along with those captured during the war, to Kazakhstan and Central Asia. Consequently, this period witnessed the establishment of numerous settlements and villages across Kazakhstan, along with an unprecedented demographic transformation within its rural population. This article delves into the demographic history of Kazakhstan's rural population from 1945 to 1955 and transformation of its landscape. The study employs a multifaceted approach, intertwining analyses of demography, social life, and migration processes prevalent during this period. Employing contemporary historical scholarship, the research investigates the nuanced interplay of various factors that shaped the demographic landscape of rural Kazakhstan during this time. It reveals a tapestry of intersecting influences that reshaped the social fabric of the region and the settlements. Through an analysis of demographic trends and migration patterns, it elucidates the profound impact of historical events and government policies on the rural people of Kazakhstan during the post-war era. By contextualizing demographic shifts within the broader socio-political frameworks, the research reveals the significance of rural population dynamics in deciphering the larger narrative of Kazakhstan's historical trajectory of human settlements.

Determining the key components of the migration policy makes it possible not only to develop and implement an efficient and effective model of the domestic migration policy, but also to assess the impact of each of its components on various spheres of the state's life. In this context, migration policy is a complex structured system that contains agreed ideas, goals, strategies, as well as measures, resources, mechanisms, and tools that interact with them, which together enable the state to regulate migration processes. Migration processes should be considered as an integral object of the state administration system, which requires the creation of certain conditions for maintaining migration within socially acceptable frameworks, in particular, ensuring both social protection of migrants and representatives of the society receiving migrants. It was established that the development of migration policy should take into account economic trends, demographic changes, political and social attitudes in society, etc. [ABSTRACT FROM AUTHOR]

Consider the following migration process based on a closed network of N queues with $K_N$ customers. Each station is a $\cdot$ /M/ $\infty$ queue with service (or migration) rate $\mu$. Upon departure, a customer is routed independently and uniformly at random to another station. In addition to migration, these customers are subject to a susceptible–infected–susceptible (SIS) dynamics. That is, customers are in one of two states: I for infected, or S for susceptible. Customers can swap their state either from I to S or from S to I only in stations. More precisely, at any station, each susceptible customer becomes infected with the instantaneous rate $\alpha Y$ if there are Y infected customers in the station, whereas each infected customer recovers and becomes susceptible with rate $\beta$. We let N tend to infinity and assume that $\lim_{N\to \infty} K_N/N= \eta $ , where $\eta$ is a positive constant representing the customer density. The main problem of interest concerns the set of parameters of such a system for which there exists a stationary regime where the epidemic survives in the limiting system. The latter limit will be referred to as the thermodynamic limit. We use coupling and stochastic monotonicity arguments to establish key properties of the associated Markov processes, which in turn allow us to give the structure of the phase transition diagram of this thermodynamic limit with respect to $\eta$. The analysis of the Kolmogorov equations of this SIS model reduces to that of a wave-type PDE for which we have found no explicit solution. This plain SIS model is one among several companion stochastic processes that exhibit both random migration and contagion. Two of them are discussed in the present paper as they provide variants to the plain SIS model as well as some bounds and approximations. These two variants are the departure-on-change-of-state (DOCS) model and the averaged-infection-rate (AIR) model, which both admit closed-form solutions. The AIR system is a classical mean-field model where the infection mechanism based on the actual population of infected customers is replaced by a mechanism based on some empirical average of the number of infected customers in all stations. The latter admits a product-form solution. DOCS features accelerated migration in that each change of SIS state implies an immediate departure. This model leads to another wave-type PDE that admits a closed-form solution. In this text, the main focus is on the closed stochastic networks and their limits. The open systems consisting of a single station with Poisson input are instrumental in the analysis of the thermodynamic limits and are also of independent interest. This class of SIS dynamics has incarnations in virtually all queueing networks of the literature. [ABSTRACT FROM AUTHOR]

This paper presents the analysis of how ISP slag addition affects the effectiveness of chloride extraction from self-compacting concrete. Corrosion processes were initiated by chloride ions added to concrete by the method accelerated with an electric field. Corrosion of reinforcement was monitored using the method of linear polarization resistance (LPR). Polarization measurements of steel reinforcement and chloride profiles were analysed to evaluate the effectiveness of electrochemical extraction. Microstructural analysis was conducted on a specimen of concrete after migration and extraction of chlorides. The presence of chloride ions and the application of an electric field during migration were tested with respect to the changed microstructure of concrete evaluated on the basis of image analysis using a scanning electron microscope (SEM). The research contributes to a better understanding of the corrosion processes caused by the presence of chloride ions in concretes in which ISP slag was used as a substitute for sand in various amounts. Thanks to the treatments of concrete with already corroding reinforcement bars, it can be concluded that the moderate replacement of sand with ISP slag limited to 25% allows for the effective inhibition of corrosion processes taking place in these concretes. However, it is not possible to completely withdraw already started corrosion processes in steel. The observations of the microstructure of concrete in which sand was completely replaced with ISP slag indicate that after prolonged use of the chloride extraction process, we can expect a change in the microstructure and the formation of ettringite, which may cause the concrete structure to burst. The obtained information will contribute to the development of modelling methods for chloride ion extraction from a wide range of currently used concretes. [ABSTRACT FROM AUTHOR]

The implementation of investment projects in the regions of the Russian Arctic requires appropriate staffing, which, in conditions of negative migration dynamics, becomes one of the key risks for them. Today, shift method is a fait accompli, which is ambiguously viewed and requires a separate careful study to enhance its positive effects and offset possible negative consequences, including achieving strategic indicators for the development of the regions of the Russian Arctic. Thus, the purpose of this study is to determine the possibilities and conditions of shift method management for the transformation of migration processes in the regions of the Russian Arctic. The scientific novelty of the study lies in the development of an approach to shift method management, which is able to change the prevailing negative migration trends in the regions of the Russian Arctic associated with population outflow. Shift method is considered as a possible reserve, which, with appropriate management, is able to change the prevailing negative demographic trends in the regions of the Russian Arctic. For this purpose, as a research method we chose written survey of employees working in shifts at one of the large Arctic enterprises. It was confirmed that the shift method can be a reserve for the transformation of migration processes in the regions of the Russian Arctic. At the same time, it is necessary to change the approach to it as an object of management, clarify its types and build a consistent policy of transition from one type to another based on the specific peculiarities of migration motivation. Detailed policy of the transition and development of certain measures, order of their implementation and formation of an integrated management mechanism that takes into account the state and the employer, will be a promising direction for further research.

The continuous arrival of young migrants is now a reality in Spain and in Barcelona in particular. Learning about and understanding the migration process is, therefore, essential to develop adequate fostering processes that meet the needs and ensure the rights of these young migrants. The purpose of this article is to explore the migration process of young people migrating to Barcelona unaccompanied, with special attention to their motivations and to their experiences during the migratory journey. A descriptive qualitative study (R&D project funded by the Ministry of Science and Innovation, RTI2018-095259-B-I00, MCIU/AEI/FEDER, UE) was conducted. This study consisted of semi-structured interviews of young migrants living at various foster centres or living on the streets, and of educators and professionals working with these young people. The results show that the conditions in their countries of origin and their search for a better future are the main reasons that motivate young people to emigrate. Extremely harsh journeys are reported as well as some surprisingly positive experiences, and this information could be an essential factor in helping to change the way that we, as receiving societies, view the migratory process of young migrants.

Non-point source (NPS) pollution has always been the focus of research worldwide, and understanding the migration process is the basis for effective control of NPS pollution. In this study, the SWAT model and digital filtering algorithm were combined to explore the contribution of NPS pollution that migrated with underground runoff (UR) process to the Xiangxi River watershed. The results showed that the surface runoff (SR) was the main migration process of NPS pollution, while the contribution of NPS pollution that migrated with the UR process only accounted for 30.9%. With the decrease in annual precipitation among the three selected hydrological years, the proportion of NPS pollution that migrated with the UR process for TN decreased, whereas the proportion for TP increased. The contribution of NPS pollution migrated with UR process varied remarkably during different months. Although the maximum total load and the load of NPS pollution that migrated with the UR process for TN and TP all appeared in the wet season, due to the hysteresis effect, the load of NPS pollution that migrated with the UR process for TP appeared 1 month later than the total load of NPS pollution. With an increase in precipitation from the dry season to the wet season, the proportion of NPS pollution that migrated with the UR process for TN and TP decreased gradually, and the degree of decrease in NPS pollution that migrated with the UR process for TP was more evident than that for TN. Besides, being affected by topography, land use, and other factors, the proportion of NPS pollution that migrated with the UR process for TN decreased from 80% in upstream areas to 9% in downstream areas, while that for TP reached a maximum of 20% in downstream areas. Based on the research results, the contribution of soil and groundwater cumulative nitrogen and phosphorus should be considered, and different managements and control measures for different migration routes should be adopted in controlling pollution.

The outflow of young people from the country for education and employment abroad is one of the most acute socio-economic problems for Kazakhstan. Taking into account the international competition in education and the imperfection of the labor market in the country, stopping the emigration of young people in the near future seems to be a difficult task. The purpose of the study is to identify and substantiate the economic aspects and factors of educational and labor migration of Kazakh youth abroad. Today, young people of Kazakhstan travel to almost all regions and countries of the world. Youth migration has both positive and negative aspects. There were developed 3 types of online questionnaires for particular categories of respondents: 1) graduates of secondary education (27 questions), 2) graduates of bachelor’s degree (27 questions), 3) young people working and living abroad (23 questions). SPSS Software was used for data analysis. The positive consequences include raising the level of qualifications and knowledge of young people, exploring new opportunities for self-realization. However, an urgent problem is a fact that the educational and labor migration of young people turns into permanent or non-return migration. The analysis allowed us to identify the dominant factors of «attraction-pushing», which have been studied and are considered as determining the migration movement of young people abroad. The combination of attracting and pushing factors influencing the migration decisions of young people can be very complex and diverse, however, in most cases, the main factors are economic, social, and demographic factors of migration.

Objectives The aim of this article is empirical exploration of the dependence of the status of a ‘stranger’ on the local and social context. In that context s/he acts as a participant of migration process that represents dynamics of the locally relativised attributes of the environment / ‘localisation’. The thesis statement concerns the interference of constitutive ecological, organizational, cultural and symbolic dimensions into the social space. Material and methods Thus the paper verifies validity of the subsequent hypotheses that ‘environment’ (coexistent attributes, fields, characteristics) that constitute the configuration of the ‘homological structures’ as defined by Pierre Bourdieu and specific for particular local communities influences perception and attitude towards a stranger. T Results The operationalisation of such complex constructs, along with the contextualisation of the migration phenomenon involving the stranger-environment relationship, leads to the adoption of an interdisciplinary research perspective, that in addition to sociology includes geographic economy, demography and spatial statistics. The analysis of the aforementioned dependencies requires a multi-source database from various surveys and administrative data (the Local Data Bank of the Statistics Poland). Conclusions The results of the analyses confirm that the main determinant of the attitude towards a stranger (as a migrant) and their status in the changing environment is the local social space (interpreted in a homologous way).

In recent years, demographic processes have rightly attracted growing attention. In addition to the natural development of the population (with the phenomena of population decline and over aging), the various forms of migration (international and inter-regional migration, core city-periphery migration) present cities with a number of political challenges. This paper describes some of the important trends, induced problems, and options for action with regard to Germany

The historical prerequisites for the formation of migration waves of the population of Ukraine are analyzed as follows: the first wave («old migration» – the second half of the nineteenth century with the predominance of migration of workers); the second wave («new migration» – the end of the nineteenth – the first half of the twentieth century. with the predominance of migration of poor peasantry); the third wave («political» – after World War II until the 1980s, with a predominance of low-skilled workers and intellectuals); the fourth wave («migrant workers», since the mid-90s of the twentieth century.). It is noted that the fifth, «intellectual» wave (since the 2010s) can be transformed into a «corporate», which provides for the withdrawal of business abroad in the context of increased tax burden in Ukraine. The likelihood of a «corporate» wave also strengthens the stimulating policy of European countries to attract businesses that offer stable economic conditions. Ukraine’s place on the global migration map confirming its inclusion in the international space as a democratic and legal State has been studied. The number of international migrants from Ukraine is gradually increasing, reaching 6.1 million people in 2020, but the problem of such dynamics is exacerbated by the declining dynamics of immigration and threatening depopulation processes: in 2020, the share of international expats in the population reached 11.9%, when in 1990 it was equal to 10.8%. Studying the migration processes of the population of Ukraine, scientists and experts often focus on the problem of human losses due to emigration. However, the modern world, even during the pandemic, is developing in the context of globalization. Many countries have an effective policy of attracting human potential, thus ensuring positive development dynamics. Therefore, the authorities of Ukraine are forced to intensify the State regulation of migration processes, guided by the consequences of their impact on socio-economic development.

The article makes an attempt to determine the primacy of the categories “migration process” and “economic crisis”. The paper analyses statistical data of the Federal State Statistic Service of the Russian Federation and the organization for Economic Cooperation and Development on migration processes in Russia. The authors study the possibility of considering the main economic directions of emigration as the reasons of economic crises. The study analyses the number of Russian citizens employed in the countries of the Organization for Economic Cooperation and Development. The article carries out a detailed study of the volume of net capital outflow by the private sector from Russia in 2019-2020. The authors make an attempt to substantiate the thesis about the root cause of migration processes in the system of global transformations. The paper justifies the need for a detailed analysis of macroeconomic indicators of development in order to build a retrospective view of the primacy of the studied processes.

Migration is a complex social process, which is not limited to territorial movement. It includes economic, labor, psychological, cultural and other aspects. In this regard, adaptation processes are an important goal of the study. They can be either successful or unsuccessful. It depends on many conditions that are classified into external and internal. The aim of the article is to analyze these factors affecting the adaptation process. The study of subjective factors of adaptation is associated with the internal motivation, attitudes, goals and motives of migrants moving in another country. The article focuses on the steps and levels of migrants integration in the host society. The determining influence on the dynamics of adaptation processes is provided by migration policy that regulates migration flows. The adaptation process itself seems either multilevel, progressive, otherwise it ends at some stage. The purpose of the article is precisely to reveal the passage of adaptation steps and levels, mainly of labor migrants located in Russia.

The growth of professional qualification and educational level with the accumulation of work experience requires a deep understanding and research of the cause-and-effect relationships of labour migration, a deep scientific analysis of current trends, identification of advantages and potential threats to the country, and the development of a developed national labour migration policy. The purpose of the paper is a theoretical analysis of the essence of migration processes as a complex system of social order. The paper uses system and theoretical methods. It was determined that the research of labour migration processes, with a few exceptions, is at an initial stage: many methodological and organisational aspects of their regulation are not properly disclosed, they lack a deep scientific understanding of the essence of migration processes as a complex socio-economic phenomenon. The paper attempts to identify the epistemological nature and essence of the migration process as a complex system of social order. Special attention is paid to the analysis of its system-forming components, which are in causal relationships and ensure its integrity, which is important for the development of an organisational and economic mechanism for regulating labour migration processes. During the study, it was established that the migration process as a complex system includes a number of interrelated stages – migration environment, migration situation, migration behaviour, migration movement, that is, mobility and adaptation of labour migrants. The paper focuses on the analysis of the initial, basic stage of the migration process – the migration environment, which determines the migration situation, under the influence of which migration behaviour is formed, and then migration mobility and the intensity of labour movements. Such an understanding of the essence of migration processes is important for the practice of regulating migration processes and the development of an organisational and economic mechanism for regulating labour movements. The analysis of each of the selected stages allows ensuring systematic and comprehensive management of labour migration processes, to increase the effectiveness of the national migration policy

Objective: This research aims to highlight the relation between precarization of work and migration, based on the understanding that migrant workers take part assisting in the economic and social development of the countries. Method: The methodology used was a systematic review of the international literature on precarious work and migration in the period from 2008 to 2018. Main results: People migrate between countries for economic, social or political factors. Common of these three reasons is the desire to have a better life conditions. Even in some cases these migrants get access to benefits, they probably will suffer some kind of precariousness - whether in unhealthy services, without legal protection or living in unsuitable housing. This is the ambivalent nature of the precarious work – and its consequences. Relevance/originality: It is observed that large part of the research on migration in the least developed countries began with propositions borrowed from researchers who codified the experience of developed countries. It is necessary in our field to present a systematic examination of how precarization and migration are addressed in the organizational studies. Theoretical/Methodological Contributions: As a contribution to the field, in this paper it is proposed a theoretical model that involves the two phenomena and, provides the reader with standardized and systematic scientific information that may assist in the development of the field by mapping existing knowledge on this subject.

At the time when prehistoric populations were uprooting and relocating themselves across much of the Southwest, an influx of thousands of immigrants possibly arrived onto the elevated and windswept terrain of Perry Mesa in central Arizona. During the Late Classic (A.D. 1280–1400), the expanded populations built large and imposing pueblos equally spaced along the mesa edge and overlooking 1000-foot cliffs. How so many people moved to Perry Mesa in late prehistory is a question we address with survey and ceramic analyses. We assess three migration scenarios: (1) a rapid deployment of a large population en masse for defense; (2) a prolonged migration stream, whereby newcomers steadily arrived to join founder groups, and (3) a scenario that truly was not a migration at all, but rather a local reorganization including the construction of the big pueblos. We also consider how the Perry Mesa case contributes to theory building for migration processes. [ABSTRACT FROM AUTHOR]

This article discusses the drivers behind why Swedes move to Portugal and who these migrants are. The conceptual framework is based on lifestyle migration and considers migration as a process. Using a semi-structured interview guide, designed according to a life-course approach, 36 in-depth interviews with Swedes permanently residing in Portugal were conducted. The findings display that only a small minority of the respondents claimed that the climate, the sense of privilege/affluence and the prospects of being a permanent tourist made them move to Portugal. A majority of the respondents expressed a disenchantment with Sweden, political correctness, and a perceived collapse of the Swedish welfare system. Simultaneously, the respondents describe an escape from everyday problems. Notably, it is not the Swedish middle-class that seems to be moving, and emigrants come from mainly the top or bottom of the social hierarchy.

The results of the analyses confirm that the main determinant of the attitude towards a stranger (as a migrant) and their status in the changing environment is the local social space (interpreted in a homologous way).

This paper explores why and how migrants use social media in different phases of the migration process, how they manage personal information on social media during migration, and whether they use libraries' social media in any of the migration phases. An anonymous questionnaire was used to collect opinions and investigate the activities of migrant communities in New Zealand in the three above mentioned areas. The paper presents the results of a descriptive statistical analysis performed on the data. These results were categorized and presented under the following themes: demographic data, use of social media during migration, personal information management practices on social media, use of library social media during migration, issues arising from the use of social media during migration and positive impact of social media during migration. The main findings of our research showed that in the transitioning phase migrants use social media mostly for making the decision to move. In the settling phase, social media help them to cushion the anxieties associated with a move and also help them to make an informed decision in the new country. In the settled phase, participants used social media to stay connected with family and friends in the home country. Language barriers can restrict the use of social media during the moving process. Personal information on social media is not recognized as important and is not managed in any particular way. Libraries are present in the life of migrants but more as physical spaces and services than through their social media presence. Findings from this study can be of interest to libraries and other information providers developing services for migrants in physical and digital environments. [ABSTRACT FROM AUTHOR]

Separation performance is the most important parameter for a continuous gas-solid separation fluidized bed. In this work, the separation process and its influencing factors in fluidized bed were studied by using a combination of stratified sampling method and sink-float tests. The results showed that the axial density distribution of coal particles was mainly determined by the density difference and fluidizing gas velocity (or bubble), while the lateral migration process was mainly affected by the moving scraper. The use of suitable operational parameters (u < 14.74 cm/s or u f < 6.0 cm/s) can reduce the bed resistance to density stratification of coal particles, thus improving the overall separation efficiency. Furthermore, under the optimum operating parameters (u f = 4.4 cm/s, u = 13.26 cm/s), the lowest possible error E value of 0.06 g/cm3 was achieved, indicating that the fluidized bed has high separation efficiency under these operating conditions. Unlabelled Image • The migration and distribution of the separated coal in the bed were analyzed. • The influencing factors of coal separation process in fluidized bed were studied. • The optimal operating parameters of the fluidized bed were determined.

Existing literature has barely explored the role of tourist experiences in the tourism-led migration process. Focusing on surfing-oriented migrants in a coastal municipality, this paper explores the relationship between the role of tourist experiences and factors influencing migrants' desires and decisions to migrate from a long-term perspective. Data transcribed from interviews about the migrants' trajectories were analyzed using the trajectory equifinality model, a qualitative research method for visualizing individuals' life courses and interrelationships between individuals and environments. This paper provides insights into the previously unexplored relationship between tourism and migration destination in tourism-led migration research. [ABSTRACT FROM AUTHOR]

Migration is a demographic process that continually accompanies human development. Migration is a social phenomenon in a globalizing world with a real impact on the lives of people, communities, countries and around the world. Migration is the need of the individual to meet the material needs - standard of living, upgrading of education, qualification, etc. The efforts of EU Member States should be aimed at pursuing a policy that is balanced, ie to look for the socioeconomic benefits of immigration. An important motive for the return of a large number of migrants to our country may be economic growth and improving living standards. [ABSTRACT FROM AUTHOR]

Objective: This research aims to highlight the relation between precarization of work and migration, based on the understanding that migrant workers take part assisting in the economic and social development of the countries. Method: The methodology used was a systematic review of the international literature on precarious work and migration in the period from 2008 to 2018. Main results: People migrate between countries for economic, social or political factors. Common of these three reasons is the desire to have a better life conditions. Even in some cases these migrants get access to benefits, they probably will suffer some kind of precariousness - whether in unhealthy services, without legal protection or living in unsuitable housing. This is the ambivalent nature of the precarious work - and its consequences. Relevance/originality: It is observed that large part of the research on migration in the least developed countries began with propositions borrowed from researchers who codified the experience of developed countries. It is necessary in our field to present a systematic examination of how precarization and migration are addressed in the organizational studies. Theoretical/Methodological Contributions: As a contribution to the field, in this paper it is proposed a theoretical model that involves the two phenomena and, provides the reader with standardized and systematic scientific information that may assist in the development of the field by mapping existing knowledge on this subject.
