Migration,the Urban Periphery,and the Politics of Migrant Lives

This paper explores the politics of migration through a focus on labor migration regimes and the urban lives of migrants in the Seoul Metropolitan Region of South Korea. In particular, it draws attention to the ways in which migrant lives highlight the limits of the contemporary emphasis on control in migration management regimes. The paper contends that while migration management certainly reworks the socio‐legal status of migrants, the desire for control is often displaced in the everyday presence and practices of migrants as urban residents. In order to develop this argument I focus on the notion of the urban periphery as a spatio‐temporal configuration that manifests marginalization but is also potentially generative, innovative and destabilizing. The paper proceeds by exploring three dimensions of the periphery: (1) the mobile commons that emerges in everyday life; (2) the process of becoming undocumented and the subversion of control; and (3) the tactics of recognition that challenge the peripheral location of migrants. In each case the focus on the urban periphery draws attention to the importance of visibility and invisibility in migration, to the uneven spatio‐temporal configuration of migrant lives in the city, and to the ways in which migrant desires constitute a politics that exceeds what is normatively expected of them.     

The Mythical Shapeshifting of Capital and Petrification of Labour: Deepening Conflict on the Agrofuel Frontier

In the great civilisations of the past, shapeshifting promised a restoration of order in turbulent times in return for the deference of loyal subjects. It was a strategy of the powerful to maintain advantage and could also be used to bind opponents to an undesired form. This study finds its resonance in the contemporary shapeshifting that is the supposed transition from the fossil fuel economy. With reference to the fusion of oil, grain and sugar companies in Brazil's ethanol sector, it explores how amidst economic, environmental and political insecurity these “old villains” of the carbon economy have fused and emerged as the “new heroes” of the green economy. Accounts of dissenting rural subjects, however, unveil the mythical nature of avowed social gains from this shapeshifting. Amidst rural conflict and a successive weakening of regulation, it becomes evident how their petrification, in a metaphorical and increasingly literal sense is required.     

Historical development of the dopamine hypothesis of schizophrenia

This review examines the history of discoveries that contributed to development of the dopamine hypothesis of schizophrenia. The origin of the hypothesis is traced to the recognition that neuroleptic drugs interfere with brain dopamine function. This insight was derived from two distinct lines of research. The first line originated from the discovery in 1956 that reserpine depletes brain serotonin. This finding resulted in a sequence of studies that led to the discovery that brain dopamine is involved in neuroleptic-induced extrapyramidal motor disturbances. The second line of research was aimed at determining the mechanism of action of psychomotor stimulants. This research produced evidence that stimulants directly or indirectly activate brain dopamine receptors. Because nonreserpine neuroleptics such as chlorpromazine block stimulant-induced movement, these findings suggested that neuroleptics were dopamine antagonists. Most previous accounts of the development of the dopamine hypothesis of schizophrenia emphasize the first line of research and ignore the second.
