From colonial superstition to the hairyman : Aboriginality and the politics of race

This is an examination of the changing representation of Aboriginality with particular focus on the characterization of Indigenous protagonists, in three twentieth century Australian narratives from the legend genre. The colonial and assimilationist discourses which inform the earlier narratives are contrasted with a recent radical alternative.

Declining woodland birds - Is our science making a difference?

Recent data from the Red List of the International Union for the Conservation of Nature show that 1240 of the world’s estimated 10 027 species of birds (12.4%) are listed as threatened (Hoffmann et al. 2010). Globally, many more are ‘declining’ in conservation status. In Europe, much attention has been given to the marked decline in the abundance and distributional extent of farmland birds associated with the intensification of agricultural production (Fuller et al. 1995; Donald et al. 2001). Recent analyses suggest woodland species alsomaynowbe experiencing significant declines (e.g. Hewson et al. 2007). In the Americas, the declining status of neotropical migrants has motivated considerable research over the last 30 years (e.g. Terborgh 1989; Robinson and Wilcove 1994). In the tropics, narrowly endemic land birds have been identified as those species most at risk of decline globally in coming decades owing to projected changes in land-use (Jetz et al. 2007). Particular taxonomic groups also are experiencing marked declines. Migratory shorebirds, for example, which depend on key stop-over sites for refuelling during intercontinental migration, are particularly vulnerable to the degradation and destruction of these sites (Barter 2002; Rogers et al. 2010). Such widespread change among the world’s avifauna has profound implications for global biodiversity, ecosystem function and the provision of ecosystem services (Sekercioglu 2006).

Zebra crossing : walking in two continents sharing and celebrating difference through music

I use the metaphor zebra crossing in my reflective narrative to describe my plight and struggle as a non-white person growing up and working in Johannesburg, South Africa, during the apartheid era. This article considers and compares the notions of culture, diversity and identity as I now work in a tertiary institution in Melbourne, Australia. I reflect on my teaching of African music and position myself as ‘the other’ at zebra crossings, as I create a space in multicultural Australia. By engaging in meaningful dialogue with music and culture, I contend, we do have opportunity to explore, experience and express music making and sharing globally. The inclusion and embracing of non-western music can serve as a dais for understanding and celebrating cultural difference not as distant experiences but as integral aspects of our daily lives.

The future of diversity and difference : can the national curriculum for English be hospitable?

This chapter explores the context of constructing the Australian Curriculum: English and how it represents and responds to the diversity of students. It starts with the brief genealogy of neoliberal standards-based reforms as a way of managing differences. In doing so, the chapter situates the national agenda of curriculum reforms in the semiotic order of ‘risk societies’ (Beck, 1992) through which various risks are both manufactured and managed. The semiotic order of managing educational risks through reforms is presented as a discursive force-field that both creates ‘moral panics’ and provides solutions, thereby appealing to the broader public and securing its consent. This discussion prepares the ground for the reading of texts produced in the lead-up to the actual release of the national curriculum for English and statements about diversity in these documents as well as in the curriculum itself. The chapter then goes on to explore what might be possible in the process of the curriculum implementation, by drawing on ideas of hospitality, responsibility and dialogism. In conclusion, this essay argues that no national curriculum can be successfully implemented unless it is sensitive to the textual and cultural practices of other groups and unless it wins their political consent. Equally, no national curriculum can be ethically implemented unless it recognises and responds to difference and unless it creates a possibility of transcending the logic of the Same.

Can the choice of interpolation method explain the difference between swap prices and futures prices?

The standard model linking the swap rate to the rates in a contemporaneous strip of futures interest rate contracts typically produces biased estimates of the swap rate. Institutional differences usually require some form of interpolation to be employed and may in principle explain this empirical result. Using Australian data, we find evidence consistent with this explanation and show that model performance is greatly improved if an alternative interpolation method is used. In doing so, we also provide the first published Australian evidence on the accuracy of the futures-based approach to pricing interest rate swaps.

Using assessment data : does gender make a difference?

Since 2000 gender differences in mathematics achievement in Australia have reappeared. In this paper we report on the achievement outcomes of girls and boys in a longitudinal study of reform in low economic school communities. Analysis of student data to inform teaching was one element of student centred approaches implemented by teachers. Teachers targeted students’ next point of learning and more girls than boys participated in mathematics intervention programs. Growth in achievement was greater for boys than for girls in the primary years, and so the achievement gap that favours males widened. It is concluded that student centred approaches need to be gender inclusive.

Student views of computer based-mathematics in the middle years : does gender make a difference?

How the use of computers in mathematics classrooms was viewed by students in two middle years mathematics classrooms was the focus of the research described in this paper. The primary data sources consisted of questionnaires, classroom observations supported by videotaping of mathematics lessons, and interviews with two girls and two boys from each class. Thus both qualitative and quantitative methods were used. Girls viewed the computer-based lessons less favourably than did boys. In general, the boys were likely to believe that computers contributed to their experiencing pleasure in these lessons, and to making mathematics more relevant to them. Girls were typically more concerned about whether computers facilitated learning and enabled success in mathematics. The attitudes of students to computer-based mathematics were related to their views of computers.

No difference in 1RM strength and muscle activation during the barbell chest press on a stable and unstable surface

Exercise or Swiss balls are increasingly being used with conventional resistance exercises. There is little evidence supporting the efficacy of this approach compared to traditional resistance training on a stable surface. Previous studies have shown that force output may be reduced with no change in muscle electromyography (EMG) activity while others have shown increased muscle EMG activity when performing resistance exercises on an unstable surface. This study compared 1RM strength, and upper body and trunk muscle EMG activity during the barbell chest press exercise on a stable (flat bench) and unstable surface (exercise ball). After familiarization, 13 subjects underwent testing for 1RM strength for the barbell chest press on both a stable bench and an exercise ball, each separated by at least 7 days. Surface EMG was recorded for 5 upper body muscles and one trunk muscle from which average root mean square of the muscle activity was calculated for the whole 1RM lift and the concentric and eccentric phases. Elbow angle during each lift was recorded to examine any range-of-motion differences between the two surfaces. The results show that there was no difference in 1RM strength or muscle EMG activity for the stable and unstable surfaces. In addition, there was no difference in elbow range-of-motion between the two surfaces. Taken together, these results indicate that there is no reduction in 1RM strength or any differences in muscle EMG activity for the barbell chest press exercise on an unstable exercise ball when compared to a stable flat surface. Moreover, these results do not support the notion that resistance exercises performed on an exercise ball are more efficacious than traditional stable exercises.
