The article explores how young Mozambican women's migratory trajectories towards Europe are shaped by sexual relationships with older white men and obligations towards female kin. Triads of exchange between young women known as curtidoras (women enjoying life) and their partners and kin in Maputo are understood through theories of patronage and exchange moralities. Searching for respect, adventure, and consumption in the sexual economy, young women at the same time struggle to ensure their families' well‐being by redistributing the money they extract from white men. Sexual‐monetary transactions, love, and desire must be understood as part of broader moralities of exchange in which migration to Europe and sending of remittances is also a kinship project. The forms of patronage available in Maputo's sexual economy become stepping stones as well as obstacles to migration northwards. 相似文献

This article focuses on ageing in transnationalism. Drawing on the experiences of Italians in the UK as a paradigmatic example of settled European migrants, it explores the lived experiences of this group of older migrants. Using Levitt and Glick Schiller's framework, it concentrates first on migrants' ways of being and then on their ways of belonging. The article argues that a transnational lens is necessary to understand the experiences of older migrants and that a focus on older people needs to be incorporated into studies of transnationalism. Through a discussion of their narratives and experiences, the article offers a long view on the migration process and brings attention to the significance of gender, time and the life course to understand both migrants' transnationalism and their integration. 相似文献

This study follows UK Afghan migrants on a return visit to Northwest Pakistan. Combining theorizations of mobility, liminality, and commensality, it takes the picnic trip (chakar) as a little‐explored cultural lens through which to analyse symbolic formations of freedom, the shaping of Pakhtun transnational labour, and social hierarchies constituted through migration and return. As potent imaginary sites of remembering and forgetting, chakar map destinations left and not‐yet arrived at, routes of flight and return, and the burden of multi‐levelled constellations of political and economic insecurity on refugees living between the UK and Pakistan. The article argues that chakar are at once therapeutic and reproductive of ways in which personal and systemic realities combine features of hierarchy, exploitation, and patriarchy. They sustain participants in a tension between desires to preserve the hierarchies they conceal, and desires for more freedom. These contradictory experiences are usefully analysed through the emblematic arc of the ‘round trip’. 相似文献

Tobacco blue mold, caused by Peronospora tabacina, is an oomycete plant pathogen that causes yearly epidemics in tobacco (Nicotiana tabacum) in the United States and Europe. The genetic structure of P. tabacina was examined to understand genetic diversity, population structure and patterns of migration. Two nuclear loci, Igs2 and Ypt1, and one mitochondrial locus, cox2, were amplified, cloned and sequenced from fifty‐four isolates of P. tabacina from the United States, Central America–Caribbean–Mexico (CCAM), Europe and the Middle East (EULE). Cloned sequences from the three genes showed high genetic variability across all populations. Nucleotide diversity and the population mean mutation parameter per site (Watterson's theta) were higher in EULE and CCAM and lower in U.S. populations. Neutrality tests were significant and the equilibrium model of neutral evolution was rejected, indicating an excess of recent mutations or rare alleles. Hudson's Snn tests were performed to examine population subdivision and gene flow among populations. An isolation‐with‐migration analysis (IM) supported the hypothesis of long‐distance migration of P. tabacina from the Caribbean region, Florida and Texas into other states in the United States. Within the European populations, the model documented migration from North Central Europe into western Europe and Lebanon, and migration from western Europe into Lebanon. The migration patterns observed support historical observations about the first disease introductions and movement in Europe. The models developed are applicable to other aerial dispersed emerging pathogens and document that high‐evolutionary‐risk plant pathogens can move over long distances to cause disease due to their large effective population size, population expansion and dispersal. 相似文献

ABSTRACT Over the past several decades, there have been numerous reports of hummingbirds wintering in the southeastern United States. However, little is known about the species present and their relative abundance. From November 1998 to March 2008, we examined the species diversity, sex and age ratios, and site fidelity of hummingbirds wintering in southern Alabama and northern Florida. We captured and banded 1598 individuals representing 10 species, and the most frequently captured species were Rufous Hummingbirds (Selasphorus rufus; 51.6%), Ruby‐throated Hummingbirds (Archilochus colubris; 23.5%), and Black‐chinned Hummingbirds (Archilochus alexandri; 16.9%). Other species captured included Buff‐bellied Hummingbirds (Amazilia yucatanensis), Calliope Hummingbirds (Stellula calliope), Allen's Hummingbirds (Selasphorus sasin), Broad‐tailed Hummingbirds (Selasphorus platycercus), Broad‐billed Hummingbirds (Cynanthus latirostris), Anna's Hummingbirds (Calypte anna), and Costa's Hummingbirds (Calypte costae). Most hummingbirds (71.8%) were captured in December and January. For most species, sex ratios were male‐biased for juveniles and female‐biased for adults, indicating possible differential mortality. Of 1598 hummingbirds captured, 144 representing five species returned to the same wintering location at least once. Female Rufous Hummingbirds (20.4% of individuals captured) exhibited the greatest site fidelity. Recaptures of banded Rufous Hummingbirds in autumn and early winter revealed that some individuals moved south into Alabama or Florida from Tennessee, northern Georgia, and northern Louisiana. Same‐season recaptures of banded Rufous Hummingbirds suggest that their spring migration route is west along the Gulf Coast. Our results suggest that Alabama and Florida are viable overwintering areas for several species of hummingbirds, with numbers of species and individuals higher than previously recognized. However, more study is needed to confirm migration routes and to determine if Ruby‐throated Hummingbirds wintering in our study area are year‐round residents or migrants. 相似文献

Aim To understand the evolution of long‐distance temperate–tropical migration in a South American bird, Swainson's flycatcher (Myiarchus swainsoni). Methods A total of 842 base pairs of the mitochondrial DNA genes ATPase 8 and 6 were sequenced from forty‐nine individuals of the M. swainsoni complex from most of its range. Analyses measured the phylogenetic signal in the data, and tools of population genetics, phylogeography and phylogeny were used to interpret the evolution of the bird and its migration on the South American landscape. Results Migratory populations in the M. swainsoni complex are not each other's closest relatives. The migratory subspecies M. s. swainsoni, which breeds in south‐eastern South America, is not closely related to the rest of the complex. The remaining migratory populations of the subspecies M. s. ferocior and two intergrade populations are extremely closely related to non‐migratory populations with which they form a well‐supported clade despite substantial morphological differentiation from each other. Within this clade of migrants and non‐migrants, net divergence across 4000 km of lowland South America is zero and most diversity is distributed among individuals not populations. Mismatch analyses and significant values of Tajima's D and Fu's Fs suggest the clade has undergone a very recent range expansion. Migration and the shifts of breeding distribution that accompanied its evolution evolved twice within what has recently been considered the polytypic species M. swainsoni. Furthermore, these shifts of range probably occurred at very different times as parts of different southward ‘pulses’ of humid, Amazonian taxa. Main conclusions Evolution of temperate‐tropical migration in the M. swainsoni complex has been spatio‐temporally layered on the South American landscape. The analysis cautions that the historical biogeography underlying a single present‐day migration system need not have been driven by a single set of environmental factors operating at one time. We suggest directions for further study of ecology and demography in zones of apparent contact between various migratory and non‐migratory populations. 相似文献

Public education remains the nation‐state's foremost instrument of forging citizens. But the emergence of ‘international education’, a system explicitly based on the ideology of globality and outside the purview of national curricula, provides a way to circumvent the citizen‐making machine. This article, based on fieldwork among Chinese secondary school students in Hungary, considers the interaction between ‘international education’ and transnational migrants in a nation‐state whose public education, as the state itself, has little interest in the ‘integration’ of non‐natives. 相似文献

ABSTRACTIn the context of shifting cultural anchors as well as unstable global economic conditions, new practices of intimacy and sexuality may become tactics in an individual's negotiation of conflicting desires and potentials. This article offers reflection on the interface between global forces, powerful transcultural narratives, and state policies, on the one hand, and local, even individual, constructions and tactics in regard to sexuality, marriage, migration, and work, on the other. The article focuses on the life trajectory of Gudiya, an ambitious young Hindu woman who started out life with little social capital and few economic resources in a dusty corner of what was then the tiny kingdom of Nepal. Gudiya's story highlights the ways in which she has engaged in relational realignments aimed at bringing her closer to the life she imagines, even as she has encountered new and persistent forms of inequality both local and transnational in scale. 相似文献

The white‐browed woodswallow Artamus superciliosus and masked woodswallow A. personatus (Passeriformes: Artamidae) are members of Australia's diverse arid‐ and semi‐arid zone avifauna. Widely sympatric and among Australia's relatively few obligate long‐distance temperate‐tropical migrants, the two are well differentiated morphologically but not ecologically and vocally. They are pair breeders unlike other Artamus species, which are at least facultative cooperative breeders. For these reasons they are an excellent case in which to use molecular data in integrative study of their evolution from ecological and biogeographical perspectives. We used mitochondrial DNA (mtDNA) to test whether they are each other's closest relatives, whether they evolved migration independently, whether they have molecular signatures of population expansions like some other Australian arid zone birds, and to estimate the timing of any inferred population expansions. Their mtDNAs are monophyletic with respect to other species of Artamus but polyphyletic with respect to each other. The two species appear not to have evolved migration independently of each other but their morphological and mtDNA evolution have been strongly decoupled. Some level of hybridization and introgression cannot be dismissed outright as being involved in their mtDNA polyphyly but incomplete sorting of their most recent common ancestor's mtDNA is a simpler explanation consistent with their ecology. Bayesian phylogenetic inference and analyses of diversity within the two species (n=77) with conventional diversity statistics, statistical parsimony, and tests for population expansion vs stability (Tajima's D, Fu's Fs and Ramos‐Onsin and Rozas's R2) all favour recent population increases. However, a non‐starlike network suggests expansion(s) relatively early in the Pleistocene. Repeated population bottlenecks corresponding with multiple peaks of Pleistocene aridity could explain our findings, which add a new dimension to accruing data on the effects of Pleistocene aridity on the Australian biota. 相似文献

From the first movements of people towards the Pacific Islands millennia ago to recent transnational migration in a globalised world, translocal mobility has been a central aspect of the social lives, cultures and histories of many Pacific Islanders. While Oceania has always been an area of migration as well as cultural and economic exchange, current transnational Pacific movements are deeply embedded in a twentieth- and twenty-first-century global phenomenon, which Castles and Miller [2009. The Age of Migration. International Population Movements in the Modern World. Houndsmill: MacMillan Press. (1993 1st edition)] have called the ‘age of migration’. This essay gives an overview of Pacific Islander migration and its patterns and motives as presented in previous studies. It shows how useful cultural categories can be for a deeper understanding of notions of moving and staying, two pluralistic and not contradictorily perceived concepts for Pacific Islanders that are crucial in transnational migration. With its focus on transnational migration and the challenges experienced by Fijians in the UK and Japan, and Micronesian Chuukese in Guam, Hawai'i, and the US mainland, this introduction concludes by analysing how the case studies presented in this special issue contribute to and complement current anthropological perspectives on Pacific Islanders’ multiple and complex forms of transnationalism. 相似文献

Transnational Migration in Rural Oaxaca, Mexico: Dependency, Development, and the Household 总被引:1,自引:0,他引:1
Contradictory models of dependency and development have dominated the discussion of migration between Mexico and the United States. Transnational models of migration resolve these contradictions by defining a series of interdependencies (economy and society, for example). Using data collected in a rural Zapotec community in Oaxaca, Mexico, this article focuses on three areas: the stage-specific development of transnational movement; the domestic cycle, household decision making, and migration/remittance outcomes; and the changing nature of community participation. Rooting the discussion in household decision making captures the important role local social variability and economic dynamism play in understanding transnational processes and advancing migration studies.

Clara Law's film Floating Life was the first Australian film to be nominated for an Oscar for Best Foreign Film, and the first Australian film to deal with migrant Hong Kong Chinese identities 'from inside'. From perspectives of transnational Chinese migration and flexible citizenship, this article looks at Floating Life as a Hong Kong Chinese migrant reading of Australia, which defamiliarizes and recontextualizes familiar Australian localities and geopolitical formations, contrasting them with the film's other principal loci of Hong Kong and Germany. It also interprets the film as a neo-Confucian study of family disintegration in a migrant context, and an exploration of notions of home and identity. 相似文献

This article addresses the life experiences and work of two contemporary Papua New Guinean artists: Saun Anti from the artistically conservative Middle Sepik River area, and Wendi Choulai, from Melbourne, Australia. Anti's story of reprimand, censorship, and banishment, and Choulai's being the antithetical situation, illustrate some hurdles faced by contemporary PNG artists. Anti's and Choulai's art posed a challenge to their people's concept of traditional forms as well as to the preconceptions of collectors and curators. They are artists torn between two worlds: the world of “tradition,” reciprocity, and initiation, and the sophisticated, cosmopolitan world of the international artist. 相似文献

Research on female migrant caregivers has tended to focus upon the emotional and social problems they encounter working abroad, given women's traditional role as caregivers for their own families. This article analyses how Caribbean women who have returned after a period abroad as domestic workers inscribe their migration experiences within the gendered narrative of the good relative who migrates to help the family left behind and therefore deserves social recognition in the community of origin. It argues that this narrative allows the women to both affirm and reinterpret local family and gender roles within the context of migration. This analysis points to the close connection between narrative structures, accounts of migration experiences, and self‐presentations and suggests that narratives about family and gender roles not only reflect people's lives, but are also a malleable resource that can be (re)shaped to validate a variety of life‐courses. 相似文献

This contribution to a roundtable on Satnam Virdee's recent Racism, Class and the Racialized Outsider praises the range, coherence and method of the book's unprecedented synthetic account. It argues that Virdee's careful consideration of race, nationality and migration changes the whole story of the working-class movement in Britain. The article closes by wondering whether the author's optimism regarding the fostering of solidarity in the recent past can fully survive scrutiny. 相似文献

Hamilton's original work on inclusive fitness theory assumed additivity of costs and benefits. Recently, it has been argued that an exact version of Hamilton's rule for the spread of a pro‐social allele (rb > c) holds under nonadditive pay‐offs, so long as the cost and benefit terms are defined as partial regression coefficients rather than pay‐off parameters. This article examines whether one of the key components of Hamilton's original theory can be preserved when the rule is generalized to the nonadditive case in this way, namely that evolved organisms will behave as if trying to maximize their inclusive fitness in social encounters. 相似文献

Accumulating evidence suggests that Atlantic populations of Leach's Storm‐Petrels (Oceanodroma leucorhoa) are experiencing significant declines. To better understand possible causes of these declines, we used geolocators to document movements of these small (~50‐g) pelagic seabirds during migration and the non‐breeding period. During 2012 and 2013, movement tracks were obtained from two birds that traveled in a clock‐wise direction from two breeding colonies in eastern Canada (Bon Portage Island, Nova Scotia, and Gull Island, Newfoundland) to winter in tropical waters. The bird from Bon Portage Island started its migration towards Cape Verde in October, arrived at its wintering area off the coast of eastern Brazil in January, and started migration back to Nova Scotia in April. The bird from Gull Island staged off Newfoundland in November and then again off Cape Verde in January before its geolocator stopped working. Movements of Leach's Storm‐Petrels in our study and those of several other procellariiforms during the non‐breeding period are likely facilitated by the prevailing easterly trade winds and the Antilles and Gulf Stream currents. Although staging and wintering areas used by Leach's Storm‐Petrels in our study were characterized by low productivity, the West Africa and northeastern Brazilian waters are actively used by fisheries and discards can attract Leach's Storm‐Petrels. Our results provide an initial step towards understanding movements of Leach's Storm‐Petrels during the non‐breeding period, but further tracking is required to confirm generality of their migratory routes, staging areas, and wintering ranges. 相似文献

How do material conditions, urban life strategies, and postcolonial medical infrastructures shape the practices of care available to patients and families in Maputo? How do global health interventions articulate with urban economies, colonial legacies, and gendered relations? Under what conditions is health made available in Mozambique's capital? This article explores these questions through the experiences of one young woman as she moves through clinical and city spaces and through changing familial and residential situations. Showing how health is shaped by gendered relations and material circumstances (or condições) as they are refracted through urban space, her experiences make clear that care both requires and creates complex material‐relational conditions rooted in clinic practice, urban forms, and gendered social and familial life. In the midst of complex medical regimes and rapidly changing urban spaces, these conditions constitute the ground on which women access medicine but also give rise to exclusions from forms of care produced by both biomedicine and social relations. Arguing for greater attention to the role of gender, urban space, economy, and exchange in theorizing health in situated urban and transnational spaces, this article advocates for accounts that go beyond biomedical and clinical framings of life, health, and well‐being and that centre relational accounts of life in the city. 相似文献
