Reading Paradigms, Toni Morrison, Beloved

Abstract: Summary This paper, which focuses on Toni Morrison's novel Beloved (1987), begins with commentary on how reading paradigms can lead to misreadings and distortions, particularly when used to mediate marginal texts. In response to that, in the discussion that follows on Beloved, a reading is given to show how, in spite of linguistic and textual givens and conventional literary and critical practice, Morrison creates a text that requires an adjustment of the “Self/Other” reading paradigm if it is to be read satisfactorily. It is also shown how in the process she corrects standard representations of the black self and through that her own writerly identity as a black female presence in conventional literary and critical practice.

Trashing the millenium: Subjectivity and technology in cyberpunk science fiction

Abstract: 'Cyberpunk’ science fiction is a self-proclaimed movement within the genre which began in the 1980s. As the name suggests, it is an extrapolative form of science fiction which combines an almost obsessional interest in machines (particularly information machines) with an anarchic, amoral, streetwise sensibility This paper sketches the development of the movement and seeks to make qualified claims for the radical. potential of its fiction. Of crucial importance are the ways in which human subjectivity (viewed in psychoanalytic terms) interacts with 'technological subjectivity' in cyberpunk, particularly with regard to implications of these interactions for oedipalization.

Synthesis and Crystal Structure of a Novel Camphor Based Thioacetal.

Abstract: * To receive any correspondence. E-mail: RAVIN-SS@pelican.vista.ac.za Chiral auxiliaries consisting of functionalised camphor skeleta have proven to be highly versatile in asymmetric reactions.1,2 They are suitable for the design of conformationally rigid derivatives and are readily available. However, chiral auxiliaries containing more than one camphor skeleton are rare.12 We wish to report the synthesis and structure of a novel thioacetal 4 comprising of two camphor skeleta. 10-Mercaptoiso-borneol 213 was synthesised by reducing camphor-10sulphonyl chloride 114 with LAH. The required exo alcohol, 10-mercapto-iso-borneol 2, was separated from the endo isomer 3 by column chromatography and characterised by NMR spectroscopy. The acetal 4 was prepared by treating compound 2 with camphorquinone followed by subsequent purification of the compound by column chromatography. The structure was elucidated by NMR spectroscopy and confirmed by X-ray crystallography (Fig. 3). It has been observed15 that treatment of camphorquinone with diols, results in formation of acetals at both C-3 and C-2 positions. In this case, the C-2 position is more hindered and the thioacetalisation occurred exclusively at the C-3 position. The regioselectivity of the reaction was determined from the NMR experiments. X-ray diffraction analysis of compound 4 was undertaken so that the stereochemistry of the product could be established. The molecular structure and absolute configuration of compound 4 is shown in Fig. 3. The structure reveals that the sulfur atom is located at the exo position and the oxygen atom at the endo position of the thioacetal moiety. The two bornane skeleta J. Chem.

Some aspects of agreement with reference to Zulu

Abstract: Die toepassing van klassifikasie-kriteria op Zulunaamwoorde soos utamatisi en ugwayi, wat tradisioneel as Klas 1a beskou word, lei tot 'n herindeling van hierdie naamwoorde in Klas 3a. Dit is verder nodig om 'n Klas 9a te onderskei aangesien sekere naamwoorde in Klas 9 soos ifonethiksi en ibhasi nie 'n nasaal, wat kenmerkend van hierdie naamwoordklas is, bevat nie. Voorts word daarop gewys dat drie verskillende dele van die naamwoordprefiks dien as basis vir die afleiding van die onderskeie kongruensiemorfeme. Laastens word aangevoer dat die demonstratiewe voornaamwoord en kwalifikatiewe/relatiewe partikel van die voile prefiks afgelei is en nie van die ware prefiks nie.
