Pasture degradation modifies the water and carbon cycles of the Tibetan highlands

The Tibetan Plateau has a significant role with regard to atmospheric circulation and the monsoon in particular. Changes between a closed plant cover and open bare soil are one of the striking effects of land use degradation observed with unsustainable range management or climate change, but experiments investigating changes of surface properties and processes together with atmospheric feedbacks are rare and have not been undertaken in the world's two largest alpine ecosystems, the alpine steppe and the Kobresia pygmaea pastures of the Tibetan Plateau. We connected measurements of micro-lysimeter, chamber, 13C labelling, and eddy covariance and combined the observations with land surface and atmospheric models, adapted to the highland conditions. This allowed us to analyse how three degradation stages affect the water and carbon cycle of pastures on the landscape scale within the core region of the Kobresia pygmaea ecosystem. The study revealed that increasing degradation of the Kobresia turf affects carbon allocation and strongly reduces the carbon uptake, compromising the function of Kobresia pastures as a carbon sink. Pasture degradation leads to a shift from transpiration to evaporation while a change in the sum of evapotranspiration over a longer period cannot be confirmed. The results show an earlier onset of convection and cloud generation, likely triggered by a shift in evapotranspiration timing when dominated by evaporation. Consequently, precipitation starts earlier and clouds decrease the incoming solar radiation. In summary, the changes in surface properties by pasture degradation found on the highland have a significant influence on larger scales.

Literary Encounters of Fundamentalism: A Case Book

Literature, literary interpretation and criticism have always had an interestingly paradoxical relationship with fundamentalism: fundamentalisms are generally built on texts, which can be sacred and exclusive, and on a claim to exclusive authority for interpretation. Therefore they tend to see the cornucopian profusion of texts and interpretations so typical of Western concepts of Literature as a threat; a circumstance which has been widely exploited by writers and critics to engage with fundamentalism on its home turf. The volume addresses the cultural given that the term ‘fundamentalism’ has acquired such wide-spread currency, at least in the West. In their various approaches, the contributions examine what fundamentalism has come to signify for those who use the term so extensively and so indiscriminately; and they try to establish what this implies for reaching more productive and positive positions in negotiating fundamentalisms. In doing so, the contributors offer investigations of literary approaches to fundamentalism across a wide range of important contemporary discourses and from a number of cultural perspectives. Readers will expand their understanding of the significance of fundamentalism, and of the value of literature as a highly specialized medium for explorations in this field.

Identity construction through phonetic crossing among young Capetonian gang members

Uncountable gangs operate in post-Apartheid South Africa, particularly in greater Cape Town, competing over turf and controlling the drug trade. Consequently, gang violence is rife in Western Cape and especially widespread in urban areas. In this paper young Capetonians’ narratives of gang violence are analyzed. In the narratives of attacks on Black or White South Africans by Coloured gang members, the Coloured narrators make use of their victims’ varieties of English, more precisely, of phonetic features. Hence, the aggressors do language crossing towards their targets when narrating their feats. Rampton (1995a:485) considers language crossing a ‘code alternation by people who are not accepted members of the group associated with the second language that they are using (code switching into varieties that are not generally thought to belong to them)’. This switching involves a transgression of social or ethnic boundaries that allows the young gangsters to construct, negotiate, uphold and manage their social identities, as language still functions as an utterly important identity marker in post-Apartheid South Africa.
