Security of Two-Party Identity-Based Key Agreement

Identity-based cryptography has become extremely fashionable in the last few years. As a consequence many proposals for identity-based key establishment have emerged, the majority in the two party case. We survey the currently proposed protocols of this type, examining their security and efficiency. Problems with some published protocols are noted.

Gesturing elsewhere: the identity politics of the Balinese death/thrash metal scene

This essay explores the political significance of Balinese death/thrash fandom. In the early 1990s, the emergence of a death/thrash scene in Bali paralleled growing criticism of accelerated tourism development on the island. Specifically, locals protested the increasing ubiquity of Jakarta, 'the centre', cast as threatening to an authentically 'low', peripheral Balinese culture. Similarly, death/thrash enthusiasts also gravitated toward certain fringes, although they rejected dominant notions of Balinese-ness by gesturing elsewhere, toward a global scene. The essay explores the ways in which death/thrash enthusiasts engaged with local discourses by coveting their marginality, and aims to demonstrate how their articulations of 'alien-ness' contributed in important ways to a broader regionalism.

Gender effects in orientation on primary students’ performance on items rich in graphics

This study investigated the longitudinal performance of 378 students who completed mathematics items rich in graphics. Specifically, this study explored student performance across axis (e.g., numbers lines), opposed-position (e.g., line and column graphs) and circular (e.g., pie charts) items over a three-year period (ages 9-11 years). The results of the study revealed significant performance differences in the favour of boys on graphics items that were represented in horizontal and vertical displays. There were no gender differences on items that were represented in a circular manner.

Physical aspects

As teachers, we must know about the physical developmental processes our students are experiencing. These are reflected in behaviour, emotions and relationships. And for adolescents, who are trying hard to figure out how the world operates, the physical changes they experience have a potent impact on their world view. While the sequencing of much of our physical development is pretty well according to a grand template and rolls out in much the same way from one person to the next, not everything occurs in a set way (Richter, 2006). Some aspects of our physical development cause other things to occur and are tied together. For example, hormonal changes during puberty are tied to the development of secondary sexual characteristics. However, there is individual variation at multiple levels, and we will discuss these. To complicate things, adolescents’ feelings and ideas about themselves and the ways in which they interact with the world as they grow and change are coloured by our societies’ multifaceted sets of ideals, standards and expectations for physical development. Many other things also impact on our conceptions of self and these will be discussed when we turn our attention to the development of identity through adolescence. In this chapter we will present some basic information about the types of physical changes to expect during adolescence, and consider some challenges that confront adolescents during this time of development.

Equal employment opportunity and diversity management : can either live up to the promise of achieving gender equity?

This paper examines the extent to which women movement into management positions. Like many other countries, this progress in Australia is slow. The paper includes discussion of the theoretical explanations for this and the extent to which these are borne out in Australia. We are aware this group represents only a minority of Australian women workers, and there are many other groups of women workers for whom constraints to women’s access to senior management may not be the most pressing issue. We have, however, chosen to focus on women in management in this paper, as while there was considerable research and public policy attention directed towards this group in the 1980s and early 1990s, over the past decade there seems to have been a reluctance to continue to address this group, despite the numerical evidence that women continue to be disproportionately represented in senior management positions. We believe it’s timely to refocus on women in management.

Gender Dilemmas in Children's Fiction

Gender Dilemmas in Children's Fiction examines how fictional texts – picture books, novels, and films – produced for children and young adults are responding to the tensions and dilemmas that arise from new gender relations and sexual differences. The book discusses a diverse range of international children's fiction published between 1990 and 2008. Some of the key dilemmas that emerge are around the texts' treatment of romance, beauty, cyberbodies, queer, and comedy.

Literacy and identity : examining the metaphors in history and contemporary research

In this review, the authors interrogate the recent identity turn in literacy studies by asking the following: How do particular views of identity shape how researchers think about literacy and, conversely, how does the view of literacy taken by a researcher shape meanings made about identity? To address this question, the authors review various ways of conceptualizing identity by using five metaphors for identity documented in the identity literature: identity as (1) difference, (2) sense of self/subjectivity, (3) mind or consciousness, (4) narrative, and (5) position. Few literacy studies have acknowledged this range of perspectives on and views for conceptualizing identity and yet, subtle differences in identity theories have widely different implications for how one thinks about both how literacy matters to identity and how identity matters to literacy. The authors offer this review to encourage more theorizing of both literacy and identity as social practices and, most important, of how the two breathe life into each other.

Gender differences in children's classroom behaviour and teacher-child relationships in early childhood: An Australian Study

Background: In the early school years, children need positive attitudes to school and experiences that promote academic and social competence. Positive relationships between children and teachers make a significant contribution to school achievement and social competence. Girls are more likely to display positive classroom behaviours and positive approaches to learning than boys. Gender differences have also been noted in teacher-child relationships. This study investigated the relationship between gender differences in classroom behaviour and gender differences in teacher-child relationships in the early years. Method: Data were drawn from The Longitudinal Study of Australian Children (LSAC). LSAC is a cross-sequential cohort study funded by the Australian Government. In these analyses, Wave 1 (2004) and Wave 2 (2006) data for 4464 children in the Kindergarten Cohort were used. Children, at Wave 2, were in the early years of formal school. They had a mean age of 6.8 years (SD= 0.24). Measures included a 6-item measure of Approaches to Learning (task persistence, independence) and teacher ratings on the SDQ. Teachers rated their relationships with children on the short form of the STRS. Results: Girls were found to have more positive relationships with their teachers and to display more positive classroom behaviours than boys. Teachers described their relationships with boys as less close than their relationships with girls and rated girls as displaying more positive approaches to learning and fewer problem behaviours than boys. Positive teacher – child relationships were significantly related to more positive classroom behaviours. The quality of the teacher-child relationship at time 1 (Wave 1) was the best predictor of the quality of the teacher-child relationship at time 2 (Wave 2). Conclusions: Findings highlight the importance of developing positive learning related classroom behaviours in understanding successful school transition and the key role played by early positive teacher-child relationships in promoting school adjustment.
