Class Struggle, Elitism and Social Collectivism in Ngugi wa Thiong’o’s Devil on the Cross : A Marxist Approach

Ngugi wa Thiong’o’s Devil on the Cross represents both an insightful interpretation and a scathing critique of Kenyan politics and society during the period of neo-colonialism. The present thesis aims to explore, with the help of Marxist ideology and criticism, the relevance of the issues of class struggle, elitism and social collectivism in the novel. At the same time, this study will attempt to define Devil on the Cross as a "national allegory" depicting situations that are common to almost all post-colonial societies, and in particular, how the novel's ideological and political commitment is an important feature as it reflects Ngugi’s effort to draw attention to how Kenya and Africa as a whole suffered from imperialism, neo-colonialism, and a corrupt and greedy capitalist society.

Towards a post-patriarchal gender order : Confronting the universality and the particularity of violence against women

The issues of gender equality and women’s human rights have become major spheres of academic debate, policy and activism in virtually every corner of the globe. Violence against women, a relative latecomer to the international gender agenda, has provided a particularly critical entry point in challenging long standing gender ideologies and taboos as well as the gender biased mainstream human rights framework that kept, until recently, the gender specific abuses women experience outside of public scrutiny.

Re-gendering labour: class and gender determinants of New South Wales electoral behaviour 1930-32

Historians have neglected tbe impact of female enfranchisement on Australian electoral outcomes. This papers employs multivariate analysis to explore electoral behaviour in New South Wales during the Great Depression. It argues that women were less prone to support Labor than men, but that women in paid employment constituted a partial exception to this pattern. In 1932 the conservative parties significantly eroded Labor's working-class support. Part of this success was due to the ability of employers to coerce workers with the threat of dismissal. Female wage earners were particularly vulnerable to this coercion. Conservative electoral appeals recast masculinity in terms of family responsibility rather than class assertion. Conflict in the household economy possibly influenced women to vote against Labor due to its identification with the cause of male breadwinners. Overall female voting behaviour was more stable than that of men and this despite the higb profile of issues that would have been expected particularly to influence female voters.

A new class of eight-membered Sn2P2O4 heterocycles. Crystal structure and electrolytic dissociation in solution of cyclo-[R2Sn(OPPh2O)2SnR2](O3SCF3)2(R=Me, t-Bu)

The syntheses of cyclo-[R₂Sn(OPPh₂O)₂SnR₂](O₃SCF₃)₂ (R = Me (1), t-Bu (2)) by the consecutive reaction of R₂SnO (R = Me, t-Bu) with triflic acid and diphenylphosphinic acid are presented. In the solid state, 1 and 2 were investigated by ¹¹⁹Sn MAS and ³¹P MAS NMR spectroscopy as well as X-ray crystallography and appear to exist as ion pairs of cyclo-[R₂Sn(OPPh₂O)₂SnR₂]²⁺ dications and triflate anions. In solution, 1 and 2 are involved in extensive equilibria processes featuring cationic diorganotin(IV) species with Sn-O-P linkages, as evidenced by ¹¹⁹Sn and ³¹P NMR spectroscopy, electrospray mass spectrometry, and conductivity measurements.

An observer design procedure for a class of nonlinear time-delay systems

This paper considers a class of uncertain, nonlinear differential state delayed control systems and presents a reduced-order observer design procedure to asymptotically estimate any vector state functionals. The method proposed involves decomposition of the delayed portion of the system into two parts: a matched and mismatched part. Provided that the rank of the mismatched part is less than the number of the outputs, a reduced-order linear functional observer, with any prescribed stability margin, can be constructed by using a simple procedure. A numerical example is given to illustrate the new design procedure and its features.

Spatial, temporal and size-class variation in the diet of estuary perch (Macquaria colonorum) in the Hopkins River, Victoria, Australia

The dietary importance of prey of estuary perch (Macquaria colonorum; Percicthyidae: Günther) was examined spatially, temporally and among size classes. Fish were collected from the Hopkins River, south-western Victoria, from September 1998 to February 1999. The species is a euryhaline, euryphagic carnivore with spatial, temporal and size class variations in diets. Fish caught from estuarine locations consumed primarily Paratya australiensis (40% IRI) while freshwater fish consumed mostly Tricopteran larvae (63.5% IRI). In both freshwater and estuarine locations, the relative importance of P. australiensis decreased with increasing length of fish. Diet changed seasonally, indicating opportunistic changes in prey. The species selected particular prey items relative to environmental availability (P. australiensis, Amarinus lacustrine).
