  • Impossible Interculturality? : Education and the Colonial Difference in a Multicultural World
  • 2014
  • Doktorsavhandling (övrigt vetenskapligt)abstract
    • An increasing number of educational policies, academic studies, and university courses today propagate ‘interculturality’ as a method for approaching ‘the Other’ and reconciling universal values and cultural specificities. Based on a thorough discussion of Europe’s colonial past and the hierarchies of knowledge that colonialism established, this dissertation interrogates the definitions of intercultural knowledge put forth by EU policy discourse, academic textbooks on interculturality, and students who have completed a university course on the subject. Taking a decolonial approach that makes its central concern the ways in which differences are formed and sustained through references to cultural identities, this study shows that interculturality, as defined in these texts, runs the risk of affirming a singular European outlook on the world, and of elevating this outlook into a universal law. Contrary to its selfproclaimed goal of learning from the Other, interculturality may in fact contribute to the repression of the Other by silencing those who are already muted. The dissertation suggests an alternative definition of interculturality, which is not framed in terms of cultural differences but in terms of colonial difference. This argument is substantiated by an analysis of the Latin American concept of interculturalidad, which derives from the struggles for public and political recognition among indigenous social movements in Bolivia, Ecuador and Peru. By bringing interculturalidad into the picture, with its roots in the particular and with strong reverberations of the historical experience of colonialism, this study explores the possibility of decentring the discourse of interculturality and its Eurocentric outlook. In this way, the dissertation argues that an emancipation from colonial legacies requires that we start seeing interculturality as inter-epistemic rather than simply inter-cultural.

  • Directional dominance on stature and cognition in diverse human populations
  • 2015
  • Ingår i: Nature. - 0028-0836 .- 1476-4687. ; 523:7561, s. 459-462
  • Tidskriftsartikel (refereegranskat)abstract
    • Homozygosity has long been associated with rare, often devastating, Mendelian disorders, and Darwin was one of the first to recognize that inbreeding reduces evolutionary fitness. However, the effect of the more distant parental relatedness that is common in modern human populations is less well understood. Genomic data now allow us to investigate the effects of homozygosity on traits of public health importance by observing contiguous homozygous segments (runs of homozygosity), which are inferred to be homozygous along their complete length. Given the low levels of genome-wide homozygosity prevalent in most human populations, information is required on very large numbers of people to provide sufficient power. Here we use runs of homozygosity to study 16 health-related quantitative traits in 354,224 individuals from 102 cohorts, and find statistically significant associations between summed runs of homozygosity and four complex traits: height, forced expiratory lung volume in one second, general cognitive ability and educational attainment (P < 1 × 10(-300), 2.1 × 10(-6), 2.5 × 10(-10) and 1.8 × 10(-10), respectively). In each case, increased homozygosity was associated with decreased trait value, equivalent to the offspring of first cousins being 1.2 cm shorter and having 10 months' less education. Similar effect sizes were found across four continental groups and populations with different degrees of genome-wide homozygosity, providing evidence that homozygosity, rather than confounding, directly contributes to phenotypic variance. Contrary to earlier reports in substantially smaller samples, no evidence was seen of an influence of genome-wide homozygosity on blood pressure and low density lipoprotein cholesterol, or ten other cardio-metabolic traits. Since directional dominance is predicted for traits under directional evolutionary selection, this study provides evidence that increased stature and cognitive function have been positively selected in human evolution, whereas many important risk factors for late-onset complex diseases may not have been.
