Beginning again: a response to Rosen and Christie

Genre theory has been around for a long time now. The exchange between Michael Rosen and Frances Christie recently featured in Changing English is the latest in a series of exchanges between advocates of genre and their critics over the past three decades or so. Our aim in this response-essay is not to weigh up the merits of the cases made by Rosen and Christie. Rather, we want to think about how individual teachers might confront the hegemony of genre theory and the harmful effects we believe it is having on language education.

Our starting point is Lisa’s own professional practice, as she enacts it from day to day at a state secondary school in the south-eastern suburbs of Melbourne, one of the most ethnically diverse regions in Australia. We draw on Lisa’s journal to construct a sense of the time and place, as well as samples of students’ writing that she gathered in the course of a year with her Year 7 class, in order to gain a better understanding of her work as an English teacher.

How does this material compare with ‘all the genre work done over some 25–30 years’ by the genre theorists? What ‘knowledge’ will she be able to construct on the basis of the classroom observations that she made over that time? What should we make of the fact that her world is not the same as the world as genre theorists conceive it?

Issues management, anticipatory systems and zombie academics

After outlining issues management the paper goes on to discuss Rosen’s notions of anticipatory systems and the concept of teleology. It suggests how these theories might be relevant to a discussion about issues management practice.

The promise of a new media and development agenda

The role of the press is underpinned by a concern for public welfare, and the discourses and debates in journalism practice and theory stem from the notion that the press is one of the pillars of a democracy and an essential element of the public sphere (Rosen, 2005; Dahlgren and Sparks, 1991). The public sphere, in turn, is linked to the theory of modernisation and the development agenda of a society, where the media are expected to play an important function as watchman, policy disseminator and teacher (Schramm, 1964). This article looks at citizen journalism’s potential to provide yet another opportunity to disadvantaged communities in India to communicate with the world, via information and communication technologies. The new media also open up the possibility of these earlier disenfranchised communities becoming partners in the country’s development and democratic agenda. This is a discussion paper based on a survey of initiatives undertaken by various community groups in India to provide a voice to local communities who would otherwise remain silent. It explores the impact of these citizen journalism initiatives on local communities vis-à-vis their effectiveness as a tool for development and social change, and argues that the growth and success of these initiatives around the world, though piecemeal, should become an important part of discourse concerning the role of journalism in society.

The teacher education evolution : the shift from online to mobile learning in curriculum, assessment and delivery

Most teacher education programs have online applications. Increasingly teacher education programs are expanding their distance education applications with mobile learning, or m-learning. Although related to online learning, m-learning focuses on the learning opportunities offered by mobile technologies. Mobile learning is a big step towards providing flexible teacher education; it has brought about a new forum for learning, decreased limitations of learning location, and provided learners with choices about how and when they access learning materials. Universities are finding themselves grappling with how best to utilize mobile technologies for learning, while staying within their educational missions and resources. In this paper the mobile devices used in higher education and the current status of mobile technologies as learning tools at universities are described. The background of approaches and methods which are currently in use are also discussed, plus universities and teacher readiness for this transformation are also reviewed. Affordances and constraints are considered.

Validating the relationship between 3-dimensional body acceleration and oxygen consumption in trained Steller sea lions

We tested the ability of overall dynamic body acceleration (ODBA) to predict the rate of oxygen consumption ([Formula: see text]) in freely diving Steller sea lions (Eumetopias jubatus) while resting at the surface and diving. The trained sea lions executed three dive types-single dives, bouts of multiple long dives with 4-6 dives per bout, or bouts of multiple short dives with 10-12 dives per bout-to depths of 40 m, resulting in a range of activity and oxygen consumption levels. Average metabolic rate (AMR) over the dive cycle or dive bout calculated was calculated from [Formula: see text]. We found that ODBA could statistically predict AMR when data from all dive types were combined, but that dive type was a significant model factor. However, there were no significant linear relationships between AMR and ODBA when data for each dive type were analyzed separately. The potential relationships between AMR and ODBA were not improved by including dive duration, food consumed, proportion of dive cycle spent submerged, or number of dives per bout. It is not clear whether the lack of predictive power within dive type was due to low statistical power, or whether it reflected a true absence of a relationship between ODBA and AMR. The average percent error for predicting AMR from ODBA was 7-11 %, and standard error of the estimated AMR was 5-32 %. Overall, the extensive range of dive behaviors and physiological conditions we tested indicated that ODBA was not suitable for estimating AMR in the field due to considerable error and the inconclusive effects of dive type.
