A landmark in the landscape of migration studies

The Age of Migration continues to play an important role in defining migration studies as a multidisciplinary field. It is primarily a textbook, although it is also used by established researchers and professionals. The book does a formidable job in providing a foundation of knowledge, albeit in a form that makes it most suited as a sourcebook to be read and digested over time. The authors seek to motivate readers with reference to the dramas of immigration in current events and politics; appeal to intellectual curiosity as a motivation for studying migration is not as well developed in the text.     

Sociology and the teaching of ethnic and racial studies

Surveys and other explorations of the teaching of ethnic and racial studies have occurred over three decades in the UK, mostly within sociology. The findings of one recent survey are discussed, along with an examination of sociology textbooks, and used to argue that the content of teaching is both more and less diverse than Michael Banton indicates, and that his account underplays the impact of audit and scrutiny exercises in higher education. This article goes on to argue that many aspects of ethnic and racial studies transcend the boundaries of sociology and other disciplines, and to use Banton's call for comparison as a launch pad to reflect on history of the discipline of sociology and how such reflections can be used to think otherwise about how we teach ethnicity and racism.     

Ethnic capital,migration, and citizenship: a Bourdieusian perspective

This article examines how ethnic capital operates in ethnic affinity migration and external citizenship. Criticizing the “methodological nationalism”, inadequate theorization of the state, and “groupist” understanding of ethnicity that characterize existing scholarship on ethnic capital, I develop an alternative account drawing on Bourdieu. I highlight the importance of state power that consecrates ethnicity as a legitimate element in classifying non-citizens and determines the key criteria for coethnicity. The conversion of ethnicity into a migration-facilitating resource, however, is not monopolized by the state. I pay attention to how aspiring migrants, assisted by various intermediaries, challenge the state’s definition of ethnic group boundaries or deliberately cultivate specific ethnic markers, with varying implications for their ethnic self-understanding. Instead of treating ethnicity as what migrants are, I analyse what states, migrants, and intermediaries do with ethnicity – how they shape the valorization, conversion, and legitimization of ethnic capital in macro-political, meso-institutional, and micro-interactional contexts, with different agendas and asymmetrical power.     

Emergent publics,critical ethnographic scholarship and race and ethnic relations

This article asks what might be the possibilities and the limits of what academic research might strive for when we engage with the politics of race. It argues for a reflexive engagement with the historically sensitive production of critical ethnographic knowledge. Ethnography and the anthropological tradition, challenged in much politically progressive literature on race and ethnicity as a form of exoticism, a medium of orientialism and a field of misrepresentation, need to be considered in interdisciplinary traditions of knowledge production in the humanities and social sciences that examine efficacy and causality as central concepts of analysis.     

Introduction: Framing difference: racial and ethnic studies in twentyfirst-century Britain

The events in Britain since the beginning of the new millennium starkly and dramatically reflect the continued salience of racial and ethnic difference. In media, political and academic discourse, the struggles over nationhood and multiculturalism, the duties of citizenship and the right to cultural expression, similarity and difference have been played out against global and national backdrops, and across many local stages. The articles in this volume aim to explore the contours of this changing terrain, and suggest new avenues for research and theorization. They are primarily an engagement with British debates and events, but seek to place these within a broader global and diasporic context. The aim of this introductory article is to sketch the background to the events that surround the production of these articles, to outline a broad conceptual overview of the current academic debates and to explore the links between each contribution.     

Measurement error in racial and ethnic statistics

In the United States, the racial and ethnic statistics published by the National Center for Health Statistics (NCHS) assume that each member of the U.S. population has a race and ethnicity and that if a member is black or white with respect to his risk of one disease, he is the same race with respect to his risk of another. Such an assumption is mistaken. Race and ethnicity are taken by the NCHS to be an intrinsic property of members of a population, when they should be taken to depend on interest. The actual or underlying race or ethnicity of members of a population depends on the risk whose variation within the population we wish to describe or explain.

Boundaries of ethnic identity in Central Asia: titular and Russian perceptions of ethnic commonalities in Kazakhstan and Kyrgyzstan

Using data from nationally representative public opinion surveys done in 2005 in Kazakhstan and Kyrgyzstan, the authors focus on the titular groups as well as the Russians in both countries and provide assessments of their perceived ethnic commonalities with one another and with various other ethnic groups, including Uzbeks and Jews in each country. The results indicate that there are hierarchies of intergroup differentiations that help to delineate the boundaries of ethnic identities in both countries. Multivariate analyses show the systematic effects of regional variables in shaping these ethnic boundaries. The basic topographies of the boundaries are consistent with the effects of social identification processes and the relative power and social standings of the different target ethnic groups across the regions. Our results lend clear support to the ethnic boundaries paradigm by underscoring that ethnic boundaries can be independent of objective commonalities and can vary according to contexts.     

A theory of ethnic violence: ethnic incorporation and ethno-political mobilization in Bulgaria and Cyprus

This article argues that the political accommodation of ethnic groups is a major determinant of ethnic violence and its effects vary depending on the pre-existing levels of mobilization. Accordingly, civic assimilationism is the most effective ethnic incorporation mode in terms of ensuring that weakly mobilized ethnic groups remain peaceful. Liberal multiculturalism is most effective in terms of eliciting peaceful mobilizations from highly mobilized ethnic groups. The ethnocratic mode tends to be the most conducive to violent mobilization at both low and high pre-existing mobilization levels. The theory is explored through case studies of Turks in Bulgaria and Cyprus. By demonstrating how the effects of ethnic incorporation policies vary depending on pre-existing mobilization levels, the article also challenges previous assumptions about the relationship between political opening and ethnic mobilization. Such an account not only explains the political determinants of ethnic violence, but also indicates potential political remedies to such problems.     

De-naturalizing the national in research methodologies: key concepts of transnational studies in migration

Abstract

Building on the transnational approach to migration, this introduction outlines some elements of the programme of an emergent methodological transnationalism. This effort aims to de-naturalize the concept of the national within migration studies. First, the analysis identifies methodological challenges of migration studies, such as contextualization, the ethnic lens and the essentializing view on ethnicity. Second, it indicates the relevant conceptual elements which deal with these methodological challenges, such as the critique of methodological nationalism, cosmopolitanism and the relational concept of space. Third, it addresses the relevant methods, such as multi-sited ethnography, the mobile methods approach, as well as researchers' positionality and strategies of de-ethnicization, all of which correspond to the new epistemology of migration studies. Finally, it highlights the common characteristics of the contributions to this special issue, which go beyond the normative view of cross-border migration.

The politics of race and sport: Resistance and domination in the 1968 African American Olympic protest movement

Using the case of the African American Olympic protest movement that grew out of the crisis of the civil rights struggle in the late 1960s, this article is an attempt to argue that work involving identity, culture and popular culture is crucial to the study of race and ethnicity in the contemporary world. A reconstruction of this movement demonstrates, first of all, how a cultural arena like sport can make it possible for otherwise powerless racial and ethnic minorities to draw attention to their cause. Of course, as with most insurgent movements, such initiatives ultimately (and often very quickly) come up against structural impediments that work to reject or absorb their challenge and reinforce the hegemony of the established regime. But the precise nature of the structural constraints operating in this particular case provides profound insight into the construction of social order in liberal democratic settings and the threat posed by cultural politics to this order. More specifically, I argue that athletic protest was overwhelmingly condemned and rejected because it threatened to rupture the homologies between sport culture and liberal democratic ideology that otherwise legitimated a fundamentally individualist, assimilationist vision of racial justice and civil rights in the United States. In more general theoretical terms, then, culturally‐oriented movements expose the ways in which domination itself is deeply structured in and through culture. The article concludes by suggesting that this, especially in an age when capital and power have discovered techniques to insulate themselves against traditional, materialist forms of resistance, is why cultural forums and identity politics have become primary sites of the struggle for hegemony.     

Diffuse, short and slow migration among Blue Tits

The knowledge of migration systems in long-distance regular migrants is in many cases extensive. Our understanding of the migratory characteristics of partial migrants, on the other hand, is far more rudimentary. We investigated migratory characteristics of partially migratory Blue Tits Cyanistes caeruleus using ringing recoveries of Swedish birds, to answer questions about geographic migration patterns, age-specific migrations, migration speeds and synchrony of movements. Median migration distance of Swedish Blue Tits was 82 km, with a main autumn direction in the sector between S and W (large directional scatter). Northerly and southerly populations did not differ in migration directions or distances, suggesting chain migration to be the general pattern. A larger proportion of adult Blue Tits remained near the breeding grounds during winter than was the case for juveniles. Some of the migrating birds (17%) seemed not to return in spring but stayed to breed closer to the winter area. Swedish Blue Tits show an exceptionally slow migration speed (median 13 km/day), among the slowest speeds recorded for any migrant bird. The Blue Tit represents an extreme case of diffuse, short and slow bird migration.     

Dynamics of ethnic and racial self-identification in contemporary Peru

This study has sought to analyse how the social and cultural dynamics of the population are expressed in the recent processes of ethnic self-identification in Peru. Data from 2012 to 2016 Peru National Household survey was used to investigate specifically: (a) on the contribution of the questions about ethnic and racial self-identification included in the National Household Survey to the visibility of indigenous and Afro-Peruvian populations; (b) on the individual and local characteristics related with certain self-identification categories; and (c) if the self-identification patterns have remained stable or have varied during the survey period. Results show that the number of persons who identifies as indigenous varies according to the question used. Likewise, it was found that characteristics such as age, migratory experience, education, and income level influence on the self-identification. Finally, modest but significant changes over time were registered, which could be shedding light on some processes of social transformations.     

Researching and teaching in the field of ethnic and racial studies: a view from continental Europe

In the first part of the article, I make a few general comments inspired by the reading of Banton's article. I claim that the field of ethnic and racial studies is often dominated by an "Anglo-Americentric" vision that leads to a negation of the variety of approaches to ethnic and racial studies throughout the world. I claim that a process of "decentration" is necessary in order to foster the diversity in our field. In the second part of the article, I make specific comments inspired by my experience as researcher and teacher in a fragmented society such as Belgium. One conclusion is that our teaching has to be contextualized in order to avoid misunderstandings and the reproduction of inadequate conceptions and confusions about ethnic and racial issues among our students.     

The use of racial, ethnic, and ancestral categories in human genetics research

The global dispersal of anatomically modern humans over the past 100,000 years has produced patterns of phenotypic variation that have exerted—and continue to exert—powerful influences on the lives of individuals and the experiences of groups. The recency of our common ancestry and continued gene flow among populations have resulted in less genetic differentiation among geographically distributed human populations than is observed in many other mammalian species. Nevertheless, differences in appearance have contributed to the development of ideas about “race” and “ethnicity” that often include the belief that significant inherited differences distinguish humans. The use of racial, ethnic, and ancestral categories in genetics research can imply that group differences arise directly through differing allele frequencies, with little influence from socially mediated mechanisms. At the same time, careful investigations of the biological, environmental, social, and psychological attributes associated with these categories will be an essential component of cross-disciplinary research into the origins, prevention, and treatment of common diseases, including those diseases that differ in prevalence among groups.     

Quantifying trophoblast migration: In vitro approaches to address in vivo situations

ABSTRACT

When trophoblasts migrate and invade in vivo, they do so by interacting with a range of other cell types, extracellular matrix proteins, chemotactic factors and physical forces such as fluid shear stress. These factors combine to influence overall trophoblast migration and invasion into the decidua, which in turn determines the success of spiral artery remodelling, and pregnancy itself. Our understanding of these important but complex processes is limited by the simplified conditions in which we often study cell migration in vitro, and many discrepancies are observed between different in vitro models in the literature. On top of these experimental considerations, the migration of individual trophoblasts can vary widely. While time-lapse microscopy provides a wealth of information on trophoblast migration, manual tracking of individual cell migration is a time consuming task that ultimately restricts the numbers of cells quantified, and thus the ability to extract meaningful information from the data. However, the development of automated imaging algorithms is likely to aid our ability to accurately interpret trophoblast migration in vitro, and better allow us to relate these observations to in vivo scenarios. This commentary discusses the advantages and disadvantages of techniques commonly used to quantify trophoblast migration and invasion, both from a cell biology and a mathematical perspective, and examines how such techniques could be improved to help us relate trophoblast migration more accurately to in vivo function in the future.     

Rejoinder: race scholarship and the future

ABSTRACT

In this Rejoinder we seek to address the key issues raised by the four commentaries on our edited book. We focus on the question of the shifting boundaries of the field of race and ethnic studies, the absences and gaps in what is covered, the limits of the post-racial, and the whitening of sociology. In conclusion, we suggest some alternative ways in which we would seek to address them.
