This paper draws upon critical discourse analysis, cultural studies and communication theory, studies on media and educational reform, and the work of Bernstein, Bourdieu and Luhmann in particular, to explore how the print and media 'mediated' a period of educational change marked by moves to self-management in schools in Victoria, Australia. It considers how the media was mobilized by various education stakeholders, and in turn informed relations between schools and government, through policy discourses and texts. It considers why and how particular themes became media 'issues', how schools and teachers responded to these issues, and how the media was used by various stakeholders in education to shape policy debates. It is based on a year-long qualitative study that explored critical incidents and representations about education in the print media over a year in the daily press. It illustrates the ways in which a neo-liberal Victorian government mobilized the media to gain strategic advantage to promote radical education reform policies, considers the media effects of this media/tion process on schools and teachers, and conceptualizes how school and system performance is fed from and into media representations, public perceptions and community understandings of schools and teachers' work.

(1R,2S,5R)-Menthyldiphenylgermane and its enantiomer have been prepared in a few steps from germanium tetrachloride. The initial step in this sequence, namely the reaction between germanium tetrachloride and menthylmagnesium chloride, produces menthylgermanium trichloride, which is the exclusive product of this Grignard reaction, presumably due to the bulk of the menthyl group. When used at a low temperature (−78 °C) and in conjunction with Lewis acids, such as magnesium salts, these chiral germanes are capable of reducing ester functionalized radicals in high enantioselectivity, but in low-moderate yield. For example, (R)-naproxen ethyl ester was obtained in 15% yield and 99% ee by reaction in toluene of 2-bromonaproxen ethyl ester with (1R,2S,5R)-menthyldiphenylgermane in toluene at −78 °C in the presence of magnesium bromide. At 80 °C, (1R,2S,5R)-menthyldiphenylgermane reacted with primary alkyl radicals with a rate constant of 1.02 × 106 M−1 s−1. Kinetic studies reveal the Arrhenius expression for this reaction to be: log(k/M−1 s−1) = (11.1 ± 0.4) − (34.6 ± 3.1)/θ where θ=2.3RT kJ mol−1.

Radical changes to the Trade Practices Act have the potential to affect significantly, the ability of businesses to engage in vigorous price competition. These changes are designed to prohibit what is colloquially referred to as predatory pricing; the practice of a firm temporarily reducing its prices to a level designed to eliminate its competitors so that, free of competition, it can thereafter, lift them to supra-competitive levels. Unfortunately, because of its scope and the ambiguous new concepts it employs, the section has the potential to apply to all forms of vigorous.price competition and creates significant risks for those businesses who.seek to compete with their rivals by systematically, or irregularly, selling at lower prices than they do. This note examines the section's nature and scope and identifies the pitfalls that it presents for such firms.

Governments expect school principals to lead and manage significant change to implement school improvement agendas. Research evidence suggests, however, that schools are slow to change (Evans, 1996; Duignan, 2006), that many teachers resist change (Marzano, Waters & McNulty, 2005), and that change is often cursory or short lived – not disrupting dominant cultures and existing arrangements (Johnson, 2004). This paper discusses the resistance to major change encountered by Australian principals, and their perceptions of its causes. Emergent themes demonstrate that the success or otherwise of change rests heavily on the political astuteness of principals, which suggests the need for ongoing professional learning and leadership support around the issue of leading and managing change.

The article demonstrates the similarity in the ways poets Lesbia Harford and Lorine Niedecker explored radical modernism. It notes the formal and thematic resemblances between the poets' writing and careers. It cites their uncanniness of poetics as an indicator of the effective global dissemination and specific political and aesthetic applications of Marxist ideologies in the early 20th century. The poets' attention to and resistance to the limitations of a gendered agency are also discussed.

A critical feminist investigation of the sexual politics of contraception over the last hundred years, within an international context. It is contended that the very idea of contraception perpetuates a "heterosexual monoculture of the body" and as a consequence, men can continue to avoid taking responsibility for their "uncontrolled" fertility.

In this radical feminist investigation of impaired practice in nursing it is argued that prejudicial and discriminatory attitudes and behaviours deriving from racism, ageism and lesbian phobia constitute impaired practice in nursing. The author's vision is that society, of which nursing would be a part, would truly care for all, regardless of race, age or sexuality.
