Purpose – The aim of this paper is to investigate whether the structure of the international migration system has remained stable through the recent turbulent changes in the world system. Design/methodology/approach – The methodology draws on the social network analysis framework – but with some noteworthy limitations stipulated by the specifics of data. Findings – The list of the most central nodes demonstrates remarkable stability over time, with the USA consistently occupying the first place and Russia and Germany stably entering the top-five (or even top-three ever since 1990). Centrality analysis also clearly demonstrates the emergence (in the 1970s) and development of the Gulf countries (particularly Saudi Arabia and UAE) as major migration destinations. Research limitations/implications – The results of the analysis present a mixture of evidence to support both the principles of the neoclassical migration theory, and some of its critiques, as the migration patterns are strongly influenced by historical links (such as colonial ties), geographical distance, cultural distance, etc. Defining the scope of influence of each of these factors lies beyond the scale of this paper. However, further application of social network analysis to studying the global migration network, in the authors ' opinion, has quite remarkable potential for contributing to this line of research. Originality/value – The paper views the specific features in the structure of the global migration network and their implications for world system studies.

People are the most important factors of economy and the primary carriers of social culture. Cross-border migration brings economic and cultural impacts to the origin and destination and is also a key to reflect the international relations of related countries. In fact, the migration relationships of countries are complex and multilateral, but most traditional migration models are bilateral. Network theories could provide a better description of global migration to show the structure and statistical characteristics more clearly. Based on the estimated migration data and disparity filter algorithm, the networks describing the global multilateral migration relationships have been extracted among 200 countries over fifty years. The results show that the global migration networks during 1960–2015 exhibit a clustering and disassortative feature, implying globalized and multipolarized changes of migration during these years. The networks were embed into a Poincaré disk, yielding a typical and hierarchical “core-periphery” structure, which is associated with angular density distribution, and has been used to describe the “multicentering” trend since 1990s. Analysis on correlation and evolution of communities indicates the stability of most communities, yet some structural changes still exist since 1990s, which reflect that the important historical events are contributable to regional and even global migration patterns.

SummaryAs a terror tactic, suicide terrorism is one of the most lethal as it relies on a human being to deliver and detonate the device. Suicide terrorism is not confined to a single region or religion. On the contrary, it has a global appeal, and in countries such as Syria, Iraq, Afghanistan, and Pakistan it has come to represent an almost daily reality as it has become the weapon of choice for some of the most dreaded terrorist organizations in the world, such as ISIS and al-Qaeda. Drawing on over two decades of extensive field research in five distinct world regions, specifically the Middle East, Western Europe, North America, Russia, and the Balkans, the author discusses the origins of modern day suicide terrorism, motivational factors behind suicide terrorism, its global migration, and its appeal to modern-day terrorist groups to embrace it as a tactic.

The Philippines is one of only two states in the world in which absolute divorce remains largely impossible. Through its family laws, it regulates the marriage, family life and conjugal separation of its citizens, including its migrants abroad. To find out how these family laws interact with those in the receiving country of Filipino migrants and shape their lives, the present paper examines the case of Filipino women who experienced or are undergoing divorce in the Netherlands. Drawing from semi-structured interviews and an analysis of selected divorce stories, it unveils the intertwined institutions of marriage and of divorce, the constraints but also possibilities that interacting legal norms bring in the life of Filipino women, and the way these migrants navigate such norms within their transnational social spaces. These findings contribute interesting insights into cross-border divorces in the present age of global migration.

AbstractThe peopling of Sahul (the combined continent of Australia and New Guinea) represents the earliest continental migration and settlement event of solely anatomically modern humans, but its patterns and ecological drivers remain largely conceptual in the current literature. We present an advanced stochastic-ecological model to test the relative support for scenarios describing where and when the first humans entered Sahul, and their most probable routes of early settlement. The model supports a dominant entry via the northwest Sahul Shelf first, potentially followed by a second entry through New Guinea, with initial entry most consistent with 50,000 or 75,000 years ago based on comparison with bias-corrected archaeological map layers. The model’s emergent properties predict that peopling of the entire continent occurred rapidly across all ecological environments within 156–208 human generations (4368–5599 years) and at a plausible rate of 0.71–0.92 km year−1. More broadly, our methods and approaches can readily inform other global migration debates, with results supporting an exit of anatomically modern humans from Africa 63,000–90,000 years ago, and the peopling of Eurasia in as little as 12,000–15,000 years via inland routes.
