Contemporary world brings along a continuing interpenetration of cultures strengthened by the migration revolution. The social space created by multiplicity of ethnic groups is very often a result of migration processes which totally formed such states as Canada or Australia. The sources of the European multiculturalism were, on the one hand, the officially accepted workforce, on the other hand – immigration being the effect of the colonial past of such states as France, Great Britain or Germany

At the ice edge krill undergoes diurnal migrations with the period of 12 hours and amplitude of about 6 meters. The mean depth of krill occurrence is 41 m, shallower then for open waters. In our opinion these migration parameters are characteristic of juvenile adolescent krill dominating at the ice edge.

In the post-communist era, the European migration space changed significantly. It has become charac-terised predominantly by temporary labour migration and new forms of circular, return and onward migration which are collectively theorised as ‘liquid’. The 2004/2007 eastward expansion of the EU resulted in the re-emergence of large-scale East-West intra-EU migration; however, Czechia continues to have one of the lowest levels of emigration among EU member-states in Central and Eastern Europe (CEE). This article analyses Czech migration to New Zealand, which constitutes a considerable portion of overall Czech emigration. It is hypothesised that this flow can be understood as an example of ‘liquid’ migration beyond the EU to a distant settler society. Data from Immigration New Zealand and Stats NZ are examined to identify the trends, patterns and sociodemographic profile of Czech-to-New Zealand migration; other secondary sources provide a preliminary sketch of the motivations behind (and lived experiences of) Czech migrants in New Zealand. The study finds that this migration is increasing – mostly for temporary work, holidaying or visiting friends and relatives – and one of the largest, young-est and most recently arrived migrant groups from the CEE EU-10 countries. It is concluded that Czechia’s comparatively high standard of living may be an explanatory factor behind the relatively large flow of its people to New Zealand and that further qualitative investigation is needed to elucidate the motivations and diverse experiences of individual Czech migrants. The article ultimately contributes to comparative migration studies by exploring a potentially unique case of liquid migration to a tradi-tional settler society.

This article provides a detailed review of the ethnosurvey, a research methodology that has been widely applied to the study of migration for almost four decades. We focus on the application of ethnosurvey methods in Mexico and Poland, drawing on studies done in the former country since the early 1980s and, in the latter, since the early 1990s (including several post-2004 examples). The second case is particularly relevant for our analysis as it refers to a number of novel migration forms that have been identified in Central and Eastern Europe in the post-1989 transition period. Drawing on these studies, we consider the advantages and disadvantages of the ethnosurvey as a research tool for studying inter-national migration. Its advantages include its multilevel design, blend of qualitative and quantitative methods, reliance on retrospective life histories and multisited data collection strategy. These features yield a rich database that has enabled researchers to capture circular, irregular, short-term and se-quential movements. Its disadvantages primarily stem from its hybrid sampling strategy, which neces-sarily places limits on estimation and generalisability and on the technical challenges of parallel sampling in communities of both origin and destination. Here we argue that the ethnosurvey was never proposed and should not be taken as a universal methodology applicable in all circumstances. Rather it represents a specialised tool which, when correctly applied under the right conditions, can be ex-tremely useful in revealing the social and economic mechanisms that underlie human mobility, thus yielding a fuller understanding of international migration’s complex causes and diverse consequences in both sending and receiving societies.

The prevalent conceptual approach used to assess multiple citizenship legislation is based on analysing a set of selected elements of the relevant legal framework. This paper argues that the evolution of legal rules on dual citizenship cannot be comprehensively analysed using methods created for comparative analyses and based on a narrow selection of legal rules that reflect either a restrictive or an open ap-proach to dual citizenship. The simplified approach that focuses on the analysis of selected fragments of explicit legislation generates results that may be misleading. Therefore, the terms of reference for comparative study of multiple citizenship should be elaborated and extended. A comprehensive compar-ative method also has to take into account the migration context as well as relevant aspects of the legal and political context. This article explores these issues through an analysis of Polish legal rules in the field of dual citizenship.

The most common chemical’s spills in typical transportation accidents are those with petroleum products such as diesel fuel, the consequence of which is an extensive pollution of the soil. In order to plan properly fuel recovery from the soil, it is important to gain information about the soil depth which may be affected by pollutant and to predict the pollutant concentration in different soil layers. This study deals with the impact of basic atmospheric conditions, i.e. air temperature and humidity on the diesel fuel migration through the soil. The diesel fuel was spilled into columns (L = 30 cm; D = 4.6 cm) filled with sandy and clay soil samples, and its concentrations at various depths were measured after 11 days under various air temperature (20 and 40°C) and relative humidity (30–100%) conditions. The effects observed were explained by understanding physical processes, such as fuel evaporation, diffusion and adsorption on soil grains. The increase in temperature results in higher fuel evaporation loss and its faster vertical migration. The relative humidity effect is less pronounced but more complex, and it depends much on the soil type.

The induction of phytoremediation by addition of complex substrates, such as sewage sludge (e.g.

from the food industry), allows for better conditions of plant growth, however, it also increases the risk of chemical compounds leaching to the soil solution. Biogenic compounds occurring in sludge such as nitrogen, organic

carbon and phosphorus when migrating with soil solution down the soil profile can lead to underground water

contamination. The paper assesses the effect of sewage sludge inducted phytoextraction of Zn, Cd and Pb with

the use of Sinapis alba L. (White mustard), Medicago sativa L. (Alfalfa) and Trifolium resupinatum L. (Persian

clover) as well as the migration of biogenic compounds (nitrogen, organic carbon and phosporus) in soil solution. Research was conducted in controlled conditions of a phytotronic chamber in which the lysimetric experiment was carried out in order to monitor the changes of total nitrogen, ammonia, phosphates, organic carbon

and pH every 3 weeks during the 112 days of the entire experiment. Based on the obtained results it was found

that there is no risk of underground water contamination by investigated substances present in sewage sludge,

because there was no indication of increased ammonia and carbon migration to the deeper parts of the soil

profile.The only exception was the migration of nitrogen compounds other than ammonia (possibly nitrates and

nitrites). Due to sewage sludge application the highest concentrations of ammonium nitrogen (211 mgN-NH4

l

-1), total nitrogen (299 mg N l-1) and organic carbon (200 mg TOC l-1) were noted at a layer of 30 cm (from top

of the column/lysimeter) after 3 weeks of the conducted process. With time a decrease of ammonium nitrogen

as well as organic carbon concentration in all columns was noted. There was no indication of phosphates in the

soil solution during the entire experiment, which was due to the high cation exchange capacity of the soil matrix.

This study analyses and compares the fertility behaviour and childbearing plans of Polish migrant fam-ilies in Ireland and those of their counterparts – families in Poland. The study has a comparative and explanatory character and applies both quantitative and qualitative methods. The analysis is based on the author’s own data collected from an online survey of Polish family units in Ireland in 2014 and compared with secondary data on families in Poland retrieved from the 2011 Gender and Generation Survey (GGS). My research reveals fertility postponement and fewer families with children among mi-grant families; nonetheless, migrant parents have more children than their counterparts in Poland. The results highlight the significance of socio-economic and institutional contexts. The study also reveals a dichotomisation of fertility strategies within the migrant population, with distinct differences in the number of children, transition age to parenthood, and further fertility intentions between migrants who became parents in Poland and those who did so after the move. The results also provide insights into the childbearing motivations and fertility patterns of recent Polish migrants and contribute to the dis-cussion of migrants’ fertility in general.

Ukraine remains today one of the main migrant sending countries in Europe, with thousands of Ukrainians working in Czechia, Italy, Poland and Russia. In this regard, Ukraine shares the previous experience of Central European countries such as the Baltic States, Poland and Slovakia, that in the 1990s and early 2000s registered first temporary, and later permanent, outflows. In more recent years, however, many Central and Eastern European countries started to register increasing numbers of immigrants and some of them have switched from net sending to net receiving migration regimes. The objective of this article is to discuss the possibility of a similar turnaround in Ukraine; to this end, we investigate the main quantitative data on mi-gration from and to Ukraine, and interpret this information in the light of selected theoretical approaches that have been used to explain migration in Central and Eastern Europe. The available data reveal high levels of labour emigration of both temporary and permanent character, the increasing propensity of mi-grants to settle down in the host countries, and the growing involvement of the youngest cohorts in the emi-gration. Despite this evidence we argue that the current situation by no means constitutes a premise for reversing the outflow from Ukraine. We conclude that the most recent improvements in general economic indicators will not lead to high levels of immigration without an active labour market policy towards foreigners.

This article explores the experiences of lesbian, gay, bisexual and transgender (LGBT) migrants from Central and Eastern Europe and the Former Soviet Union in Scotland. Drawing on interviews with 50 migrants, the article focuses on the experiences and aspirations which they articulate as being part of ‘a normal life’, and analyses them within broader conceptual understandings of security and ‘normal-ity’. We first examine how normality is equated with an improved economic position in Scotland, and look at the ways in which this engenders feelings of emotional security and well-being. We then explore how more positive experiences around sexuality and gender identity are key to a sense of emotional security – i.e. of feeling accepted as ‘normal’, being visible as an LGBT person but ‘blending in’ rather than standing out because of it. Finally we look at the ways in which the institutional framework in Scotland, in particular the presence of LGBT-affirmative legislation, is seen by participants to have a normalising effect within society, leading to a broader sense of inclusion and equality – found, again, to directly impact upon participants’ own feelings of security and emotional well-being. The article engages with literatures on migration and sexuality and provides an original contribution to both: through its focus upon sexuality, which remains unexplored in debates on ‘normality’ and migration in the UK; and by bringing a migration perspective to the debates in sexuality studies around the normal-ising effect of the law across Europe. By bringing these two perspectives together, we reveal the inter-rela-tionship between sexuality and other key spheres of our participants’ lives in order to better understand their experiences of migration and settlement.

In this paper we review the significant political events and economic forces shaping contemporary mi-gration within and into Europe. Various data sources are deployed to chronicle five phases of migration affecting the continent over the period 1945–2015: immediate postwar migrations of resettlement, the mass migration of ‘guestworkers’, the phase of economic restructuring and family reunion, asylum-seek-ing and irregular migration, and the more diverse dynamics unfolding in an enlarged European Union post-2004, not forgetting the spatially variable impact of the 2008 economic crisis. In recent years, in a scenario of rising migration globally, there has been an increase in intra-European migration com-pared to immigration from outside the continent. However, this may prove to be temporary given the convergence of economic indicators between ‘East’ and ‘West’ within the EU and the European Eco-nomic Area, and that ongoing population pressures from the global South, especially Africa, may inten-sify. Managing these pressures will be a major challenge from the perspective of a demographically shrinking Europe.
