Racial Differentiation

This paper traces senses of injustice among Indian Malaysians which found expression in the ‘illegal’ Hindraf rally in Kuala Lumpur in 2007. While underlying ethnic and racial differentiation has been rendered through law in the post-colonial nation-state, the focus here is on a specific locality: resettlement flats for Indians displaced for the construction of Malaysia’s federal government administrative centre, Putrajaya. Ex-plantation workers are shown to be symbolically peripheral (to the spectacular ‘national landscape’ of Putrajaya) and to have experienced everyday forms of ethnicised marginalisation. The rally in the commercial heart of Kuala Lumpur—involving tens of thousands of Indian Malaysians from across peninsular Malaysia—mobilised what were previously largely localised grievances such as those associated with the Putrajaya estate evictions. It is shown how this ethnic transgression not only contests the ‘second-class’ position of Indians in Malaysia, but may also contribute to a redrawing of the ethnic contours of Malaysia’s legal and political landscape. More broadly, the Hindraf events also serve as a reminder that rights and social justice claims expressed in key urban centres continue to have important national-scale dimensions, even in an ostensibly neo-liberalised global economy.

AbstractThis article contends that understandings of race and practices of racial differentiation underwent a significant epistemological shift around the first decades of the twentieth century. It reaches this conclusion via consideration of a dog breeding programme conducted by the statistician and hereditarian theorist Karl Pearson. In 1913, Pearson proclaimed that he, along with his collaborators Edward Nettleship and Charles Usher, had created a ‘new race’ of dog. Notable for its complete absence of hair pigmentation, this race appeared to demonstrate the potential that experimental animal breeding had for imperial policy-making. In differentiating his dogs from the Pekingese spaniels from which they had been produced, Pearson sought to show that ‘foreign’ animals could be made to approximate British racial standards. In Pearson's wake, animal breeding became an increasingly persuasive means by which scientists sought to legitimate racial contentions. By the 1920s, established anthropocentric approaches to human differentiation had begun to be replaced by new, animal-centred techniques and practices. Whereas nineteenth-century conceptions of race had primarily been articulated in relation to the study of human bodies, in the new race of the twentieth century, differentiation would involve study of and experimentation with bodies of all kinds – animal and human.

The environmental conditions under which signals are perceived can affect receiver responses. Many songbird populations produce a song chorus at dawn, when, in cold habitats, they would experience thermal challenge. We recorded temperature and the song activity of Lincoln's sparrows ( Melospiza lincolnii ) on a high-elevation meadow, and determined that song behaviour is concentrated around the coldest time of the day, at dawn. We hypothesized that this is because male song in the cold is more attractive to females than song in the warm. To test this, we exposed laboratory-housed Lincoln's sparrow females to songs at 1°C and 16°C, which they naturally experience in the wild. Females spent 40 per cent more time close to the speaker during playback at 1°C than at 16°C. When tested at 16°C 1–2 days later, females biased their movement towards the speaker playing songs previously heard at 1°C over 16°C. Thus, female Lincoln's sparrows remembered and affiliated with songs they heard under thermal challenge, indicating that the thermal environment can affect the attractiveness of a sexual signal.
