Principals, politics and change : confronting school resilience to radical renewal

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.

An uncanny vernacular : comparing the radical modernisms of Lorine Niedecker and Lesbia Harford

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.

Fertile bodies - the sexual politics of contraception : a radical feminist perspective

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.

Notion of impaired practice in nursing : a radical feminist perspective

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.

Radical epistemological skepticism about justified belief

"Radical epistemological skepticism" designates the philosophical position that all our beliefs, and knowledge based upon them, are groundless. Skeptics claims have been recorded throughout history and, despite their threat to the security of human knowledge, they endure. The thesis hypothesises that skepticism is a consequence of our development of symbolic capability.

Radical conservative experiment in New South Wales education

This study, written from the perspective of a parent activist, articulates the 'battle of ideas' or struggle 'around the truth' of public education in New South Wales since the conservative Greiner government came to power in 1988 and instituted the 'new right' agenda. Political control is theorised in the light of debates about hegemony, power, ideology and truth. Documents what happened in 'consultations' about educational reform between the Ministers and their appointees on on the one hand, and the public education lobby, on the other.

Investigation into the application of chiral organotin hydrides as enantioselective free radical reducing agents

Investigates the viability of selectively preparing molecules demonstrating the property of left or right "handedness" via free radical reactions. Experimental investigations suggested that a subtle interaction exists between the substituents of an organotin hydride and a target carbon radical during hydrogen atom transfer reactions.

Pulsed plasma polymerization of hexamethyldisiloxane onto wool : control of moisture vapor transmission rate and surface adhesion

A new fabric with potential in medical textiles has been developed by application of a surface coating on wool using pulsed plasma polymerization of HMDSO. This coating enabled a controllable MVTR and surface adhesion. MVTR in the range recommended for optimum wound healing was obtained by varying frequency, monomer pressure and deposition time. Lower surface adhesion was achieved. Peeling tests, contact angle measurements, SPM force curves and ATR FT-IR were used to characterize the surfaces for both wool and a PE model substrate. All these results were consistent with a decrease in surface energy after PP-HMDSO treatment. ATR FT-IR results showed a siloxane film with less organic Si(CH₃)_n groups and more SiOSi cross-links.

High-performance liquid chromatography with post-column 2,2′-diphenyl-1-picrylhydrazyl radical scavenging assay : methodological considerations and application to complex samples

An improved post-column 2,2´-diphenyl-1-picrylhydrazyl (DPPH•) radical scavenging assay for the screening of antioxidants in complex matrices was developed. Experimental parameters believed to be influential to DPPH• response were studied in a univariate approach. Optimum conditions were found to be: 5×10⁻⁵M DPPH• reagent prepared in a 75% methanol: 25% 40mM citric acid–sodium citrate buffer (pH 6) solution, degassed with nitrogen; reaction coil of 2m×0.25mm i.d. PEEK tubing; detection at 521 nm; analysis at room temperature. The analytical utility of this protocol was evaluated by screening for antioxidants in thyme and green tea, in comparison with two commonly employed methodologies.

Identity as radical alterity : critiques of Eurocentrism, coloniality and subjectivity in contemporary Australian and Latin American poetry.

This article presents a comparative analysis of Australian and Latin American contemporary poetry which is informed by theories of Eurocentrism derived from contemporary Latin American critical thought.
