This article provides a close reading of Geraldine McCaughrean’s award-winning novel, The White Darkness. It argues that this is a key text in the increasing debate about ‘crossover’ literature. Whereas, traditionally, adolescent
books were seen to offer compensatory fantasies to the adolescent reader, McCaughrean’s text goes beyond this, exploring adolescence
in deeper terms: not simply as an age-defined period but as a time when the traditional coordinates of the self are thrown
into crisis, or become destabilized (as an ‘open psychic structure’, as Kristeva puts it). Adopting such a psychoanalytical
approach, it is argued, we can begin to understand this book’s appeal (and others like it) to adolescent and adult alike;
that is, it stages a shift from an imaginary identification with a stable self to a more realistic, albeit less secure recognition
of the flimsiness of identity. The white wastes of Antarctica provide the perfect backdrop for this confrontation with the
ungraspable Real.

This article highlights the importance of using polar coordinates when studying functions, in particular in relation to generalized h-type indices. Concretely, generalized h-type indices are essentially polar coordinates. This observation ties informetric ideas to standard mathematics. This article is essentially meant to provide tools for further studies. 相似文献
