Development of more sophisticated techniques for modeling longitudinal data has implications for improving our understanding of migration. This paper uses longitudinal data from the British Social Change and Economic Life initiative to disentangle the effects of population heterogeneity, progress through the life cycle and secular change on observed migration differentials. The data consist of retrospective life histories from people sampled in several contrasting localities in Great Britain, in which residential moves can be linked to changes in occupation and household structure. We present a framework for analysis of data of this type using a generalized linear modeling approach, together with results concerning variations in the probability of migration with age, gender, and changes in household and occupational circumstances. Of particular note is the evidence of substantial duration-of-residence effects and an unexpected later-career increase in migration propensity. 相似文献

This collection translates some of the work of the influential Black Brazilian thinker and activist Beatriz Nascimento (1942–1995) for the first time into English, in collaboration with her only daughter, Bethânia Gomes. Historian, poet, theorist and organiser, Beatriz Nascimento was a key figure in Brazil’s Black Movement until her untimely death in 1995. She dangerously wrote at the height of Brazil’s Military Dictatorship (1964–1985), and theorised extensively on the Black condition in Brazil; the unique experience of Black women; and quilombos—Brazilian maroon societies that she imagined as spaces of both historical and contemporary fugitivity. Following Alex Ratts, this introduction outlines her contribution to radical geography, in particular Black geographies, territoriality and embodiment. It also positions Nascimento within the trans‐Atlantic Black radical tradition. We present two of Nascimento’s essays in translation here. The first, “The Concept of Quilombo and Black Cultural Resistance”, introduces a crucial strand of her scholarly work, on the history and socio‐political significance of quilombos (maroon communities). The second, “For a (New) Existential and Physical Territory”, shows Nascimento in a different mood: philosophical, reflective and iconoclastic. In addition, two of her poems—“Dream” and “Sun and Blue”—are also translated here for the first time. 相似文献
