Is proof dead in the age of computers?

Some knowledge of what it means to construct a proof is an extremely important part of mathematics. All mathematics teachers and students should have some exposure to the ideas of proof and proving. This paper deals with the issue of creating proofs in mathematics problems.

Validity and reliability of measures of television viewing time and other non-occupational sedentary behaviour of adults : a review

Time spent in non-occupational sedentary behaviours (particularly television viewing time) is associated with excess adiposity and an increased risk of metabolic disorders among adults; however, there are no reviews of the validity and reliability of assessing these behaviours. This paper aims to document measures used to assess adults' time spent in leisure-time sedentary behaviours and to review the evidence on their reliability and validity. Medline, CINAHL and Psych INFO databases and reference lists from published papers were searched to identify studies in which leisure-time sedentary behaviours had been measured in adults. Sixty papers reporting measurement of at least one type of leisure-time sedentary behaviour were identified. Television viewing time was the most commonly measured sedentary behaviour. The main method of data collection was by questionnaire. Nine studies examined reliability and three examined validity for the questionnaire method of data collection. Test–retest reliabilities were predominantly moderate to high, but the validity studies reported large differences in correlations of self-completion questionnaire data with the various referent measures used. To strengthen future epidemiological and health behaviour studies, the development of reliable and valid self-report instruments that cover the full range of leisure-time sedentary behaviour is a priority.

The decline of experts in the Age of web 2.0 : lay blogger perceptions of experts

With the advent of Web 2.0 tools such as Weblogs (blogs), lay people can more easily share knowledge with the public and have far greater reach and impact. At the same time a literature review reveals that experts have been criticised on many fronts. This paper explores key criticisms of experts using 1) a literature review and 2) an interpretive study of lay blogger perceptions of experts. The paper provides important insights into lay blogger criticisms of experts. Findings indicate that a major lay blogger criticism of experts is class-based and powerbased. Experts are perceived as elitists who wish to control the flow of knowledge. Interestingly, many of the lay bloggers studied held mixed feelings about experts and the value of lay knowledge on the internet. Implications for theory and practice are discussed.

The age of criminal responsibility

In recent times there have been claims that the sentencing of serious juvenile offenders does not reflect community sentiment and legal policies are based on outdated ideas about adolescent development. The findings of this thesis call into question the suggestions that the law's assumptions about the development of competence is out of step with community attitudes and developmental research. The professional portfolio examines several hypotheses that have been generated to explain why disabled individuals engage in sexually inappropriate behaviour. It also highlights the importance of exploring the aetiology of this behaviour. Four case reports are presented.

New Zealand higher education in the age of technological convergence

There are competing discourses within New Zealand higher education on the impact of the converging 'forces' of technology, globalisation and corporatisation. Educational leadership in NZ exhibits a demonstrably weaker response compared with the literature and elsewhere. The current behaviour of media organisations may be indicative of any future educational response.

Risk and the regulation of youth(ful) identities in an age of manufactured uncertainty

Examines the benefits and dangers of allowing experts to intervene in the lives of youth, and their families, on the basis of assessing them as being at-risk.  Highlights the dangers of expert promises to prevent risk by intervening in people's lives on the basis of what is perceived to be normal or good.

Tertiary education for social justice in an age of uncertainty

This thesis is concerned with tertiary teachers in a range of disciplines who focus on social justice. It found that current conditions of tertiary education are challenging for teachers and suggested that a "capabilities" approach can provide the basis for attending to professional and ethical issues for tertiary teachers.

Avatar Obama in the age of liquid celebrity

Barak Obama, orator extraordinaire, the embodiment of the American success myth, 'global' prophet of the adoring masses and multi-media auratic figure, is the leading illustration of what is the expanded nexus of celebrity, spectacle and politics in the age of what Zygmund Bauman refers to as liquid modernity or 'the era of disembedding without re-embedding' (2001, p. 89). This is the era in which a traumatic sense of fear, uncertainty and transience defines one's relationship to the nation state, and social (media) centre, as they lose their economic singularity and cultural coherency and cohesiveness in a world system ever inter-connected and driven increasingly, incessantly by supra-corporate concerns and spectacular celebrity-based presentations. In this world of 'togetherness dismantled' (Bauman 2003, p. 119), the disenfranchised individual feels they cannot meet the trans-capital intensive, show reel-like, boundaryless world on solid ground. That adoration, or a liquefied definition of it, is key to this imagined and affective communion between Obama and those who adore him, suggests that there is a terrible wanting and simultaneous waning to those who look for such rootedness and the promise of deliverance in the celebrity political figure. This is a charismatic authority figure who promises this solidity yet streams in and out of material view, unable to fix or properly propagate their communion beyond triumphant spectacularism. Their 'lightness of being' (ibid, p. 123-9) is powerfully seductive and decidedly empty because it echoes the instantaneous (instant) way in which all lives are increasingly led. I will suggest that liquid celebrity is one of the cornerstones of liquid modernity, and Barack Obama is the epitome of this 'runniness'.

Youth as an artefact of expertise : problematizing the practice of youth studies in an age of uncertainty

At the start of the 21st century the Liberal democracies, including Australia, are characterized by profound social, economic and cultural transformations. Community, policy and academic discourse is marked by widespread adult anxieties about today’s young people. Representations of youth in the institutional domain of ‘youth studies’ can be conceived as artefacts of the activities of diverse forms of expertise. This paper will focus on the institutionalized processes of abstraction which construct these truths, and the roles played by these processes of abstraction in the restless problematization of ‘youth’ as the object of countless competing and complementary governmental programmes. There has been, in recent years, increased debate about how to do youth studies and how to represent youth. The paper will argue that any rethinking or reassessment of the modes of representing youth ought to take some account of the institutional and abstract nature of these processes of representation, and of the implication of these processes in the regulation of populations of young people; populations which are rendered knowable in all their diversity only through these processes of representation.

Research methodologies in creative practice : literacy in the digital age of the twenty first century - learning from computer games

Literacy remains one of the central goals of schooling, but the ways in which it is understood are changing. The growth of the networked society, and the spread of Information and Communications Technologies (ICT), has brought about significant changes to traditional forms of literacy. Older, print based forms now take their place alongside a mix of newer multi-modal forms, where a wide range of elements such as image, sound, movement, light, colour and interactivity often supplant the printed word and contribute to the ways in which meaning is made. For young people to be fully literate in the twenty-first century, they need to have clear understandings about the ways in which these forms of literacy combine to persuade, present a point of view, argue a case or win the viewers’ sympathies. They need to know how to use them themselves, and to be aware of the ways in which others use them. They need to understand how digital texts organise and prioritise knowledge and information, and to recognise and be critically informed about the global context in which this occurs. That is, to be effective members of society, students need to become critical and capable users of both print and multimodal literacy, and be able to bring informed and analytic perspectives to bear on all texts, both print and digital, that they encounter in everyday life.

This is part of schools’ larger challenge to build robust connections between school and the world beyond, to meet the needs of all students, and to counter problems of alienation and marginalisation, particularly amongst students in the middle years. This means finding ways to be relevant and useful for all students, and to provide them with the skills and knowledge they will need in the ICT-based world of the Twentyfirst century. With respect to literacy education, engagement and technology, we urgently need more information as to how this might be best achieved.
