  Talking about Gypsies: The Notion of Discourse as Control

  摘要：

  Gypsies and Travellers are increasingly part of a debate by politicians and the media in the UK. This discourse is not a benign reflection of events; instead it is part of a complex mechanism of control. There is a difficult relationship between the settled and travelling communities which inhibits political discussion of a strategy for site provision. In this context, the paper examines the links between discourse and control, by paying attention to Foucaultian notions of the 'gaze', amongst other explanations. Drawing on findings from analysis of the media, focus groups with Travellers and a case study in one local authority planning consultation exercise, the paper proposes a theoretical explanation for the link between the discourse used around Gypsies and Travellers and the control that is exercised over them, particularly in inhibiting their right to a travelling lifestyle.

  A new way toward Z.alpha.,.beta. unsaturated esters: a pyrethroid application

  摘要：

  Use of the stereospecific condensation of beta-carbalkoxysulfones with aldehydes, followed by the stereospecific reduction of the afforded sulfonyl acrylate with sodium dithionite allows us to propose this method as a new way to prepare Z alpha,beta unsaturated esters. Steric hindrance seems to be the reason for the selectivity of the reduction and the mechanism was proved, by X-ray of an intermediate, to be a cis Michael addition of HSO2-, followed by an anti elimination of SO2 and the sulfinate group. This method discovered in the pyrethroid series for the synthesis of acrinathrin 1 could have general application.

  Nanocrystalline magnesium oxide was found to be an effective heterogeneous, solid base catalyst for the one-pot Wittig reaction to afford α,β-unsaturated esters and nitriles in excellent yields with high E-stereoselectivity in the presence of triphenylphosphine under mild conditions.

  发现纳米晶氧化镁是一种有效的非均相，固态碱催化剂，可在一锅Wittig反应中以温和条件在三苯基膦存在下以高收率和高E-立体选择性以优异的产率提供α，β-不饱和酯和腈。

  The B(C6F5)3-catalyzed transesterification of a series of 3-alkenyl-oxindoles and other unsaturated tert-butyl esters with aryl-diazo esters is reported. This protocol is facile and generally high yielding proceeding under mild conditions and is remarkably chemoselective leaving the CC bonds intact.
