Multi-factor password-authenticated key exchange

We consider a new form of authenticated key exchange which we call multi-factor password-authenticated key exchange, where session establishment depends on successful authentication of multiple short secrets that are complementary in nature, such as a long-term password and a one-time response, allowing the client and server to be mutually assured of each other's identity without directly disclosing private information to the other party. Multi-factor authentication can provide an enhanced level of assurance in higher-security scenarios such as online banking, virtual private network access, and physical access because a multi-factor protocol is designed to remain secure even if all but one of the factors has been compromised. We introduce a security model for multi-factor password-authenticated key exchange protocols, propose an efficient and secure protocol called MFPAK, and provide a security argument to show that our protocol is secure in this model. Our security model is an extension of the Bellare-Pointcheval-Rogaway security model for password-authenticated key exchange and accommodates an arbitrary number of symmetric and asymmetric authentication factors.

The influence of national culture on communication practices : a case study on Malaysian organisation

National culture is deeply rooted in values, which are learned and acquired when we are young (2007, p. 6), and „embedded deeply in everyday life. (Newman & Nollen, 1996, p. 754). Values have helped to shape us into who we are today. In other words, as we grow older, the cultural values we have learned and adapted to will mould our daily practices. This is reflected in our actions, behaviours, and the ways in which we communicate. Based on the previous assertion, it can be suggested that national culture may also influence organisational culture, as our „behaviour at work is a continuation of behaviour learned earlier. (Hofstede, 1991, p. 4). Cultural influence in an organisation could be evidenced by looking at communication practices: how employees interact with one another as they communicate in their daily practices. Earlier studies in organisational communication see communication as the heart of an organisation in which it serves, and as „the essence of organised activity and the basic process out of which all other functions derive. (Bavelas and Barret, cited in Redding, 1985, p. 7). Hence, understanding how culture influences communication will help with understanding organisational behaviour. This study was conducted to look at how culture values, which are referred to as culture dimensions in this thesis, influenced communication practices in an organisation that was going through a change process. A single case study was held in a Malaysian organisation, to investigate how Malaysian culture dimensions of respect, collectivism, and harmony were evidenced in the communication practices. Data was collected from twelve semi-structured interviews and five observation sessions. Guided by six attributes identified in the literature, (1) acknowledging seniority, knowledge and experience, 2) saving face, 3) showing loyalty to organisation and leaders, 4) demonstrating cohesiveness among members, 5) prioritising group interests over personal interests, and 6) avoiding confrontations of Malaysian culture dimensions, this study found eighteen communication practices performed by employees of the organisation. This research contributes to the previous cultural work, especially in the Malaysian context, in which evidence of Malaysian culture dimensions of respect, collectivism, and harmony were displayed in communication practices: 1) acknowledging the status quo, 2) obeying orders and directions, 3) name dropping, 4) keeping silent, 5) avoiding questioning, 6) having separate conversations, 7) adding, not criticising, 8) sugar coating, 9) instilling a sense of belonging, 10) taking sides, 11) cooperating, 12) sacrificing personal interest, 13) protecting identity, 14) negotiating, 15) saying „yes. instead of „no., 16) giving politically correct answers, 17) apologising, and 18) tolerating errors. Insights from this finding will help us to understand the organisational challenges that rely on communication, such as during organisational change. Therefore, data findings will be relevant to practitioners to understand the impact of culture on communication practices across countries.

Conveying identity with mobile content

A series of mobile phone prototypes called The Swarm have been developed in response to the user needs identified in a three-year empirical study of young people’s use of mobile phones. The prototypes take cues from user led innovation and provide multiple avatars that allow individuals to define and manage their own virtual identity. This paper briefly maps the evolution of the prototypes and then describes how the pre-defined, color coded avatars in the latest version are being given greater context and personalization through the use of digital images. This not only gives ‘serendipity a nudge’ by allowing groups to come together more easily, it provides contextual information that can reduce gratuitous contact.

Perceptions of acculturation and social identity construction among three Taiwanese/Chinese migrants in Australia

In recent years, increasing numbers of Chinese migrants have come to Australia to study or to live. In doing so, they have entered a new cultural space. They are faced with many challenges, not only to do with study experience, workplace experience and life-style practices, but also to do with language, communication, culture and identity. Such new challenges can feel dangerous, unstable and uncomfortable as they require moves out of the safety zone of primary cultural experience. This qualitative research study investigates the perceptions and narratives of three Taiwanese-Australian migrants in terms of their experience of this process of acculturation and social identity construction as migrant tertiary students in the new Australian context and of their subsequent experience professionally. Their accounts of where they see themselves to have 'landed' in terms of their acculturation process and identity construction might provide relevant insights to the experience of hybridity which is intercultural Australia.

The graduate attributes we've overlooked : enhancing graduate employability through career management skills

Recent shifts in education and labour market policy have resulted in universities being placed under increasing pressure to produce employable graduates. However, contention exists regarding exactly what constitutes employability and which graduate attributes are required to foster employability in tertiary students. This paper argues that in the context of a rapidly changing information- and knowledge-intensive economy, employability involves far more than possession of the generic skills listed by graduate employers as attractive. Rather, for optimal economic and social outcomes, graduates must be able to proactively navigate the world of work and self-manage the career building process. A model of desirable graduate attributes that acknowledges the importance of self-management and career building skills to lifelong career management and enhanced employability is presented. Some important considerations for the implementation of effective university career management programs are then outlined.

There, yet not there : human relationships with technology

There is a “reality” to being online which we know to be false. We are simultaneously “there” but “not there” as we talk, work and play with others in online spaces. We move between physical and virtual spaces in ways that realise the predictions made for computers in the mid-20th Century and enact scenarios from science fiction. We are left wondering if our thoughts - through our disembodied selves - have become a “second self” or if we have become part of the machine itself. Information and communication technology (ICT) have brought differing human and technological agencies to all aspects of contemporary life including teaching and learning. This paper attempts to identify and categorise these agencies through the genres of technics and to illustrate them – and our relationships with technology - through reference to philosophy, fiction and reality. It also stands as an introduction to this special issue on the agency of technology.

Appreciating diversity: Confronting homophobia at school

The development of sexual identity is a complex, lifelong process involving the interplay of sex, gender and orientation, occurring within a social framework of heterosexual dominance (Murray 2001). Australia has a richly diverse culture and, at some point in our lives, we will all meet people, who look, think, live, or act differently to ourselves. Through understanding and celebrating the diversity of our culture, we enrich our lives and the lives of others. Schools influence how boys (and girls) see themselves and each other; those of us who work in schools cannot pretend to be outside the process of gender construction. In our daily business we send messages, set boundaries and respond with support, disinterest or censure to the acting out of various masculinities and femininities.

Identity and text : developing self-conscious readers

Globalisation and societal change suggest the language and literacy skills needed to make meaning in our lives are increasing and changing radically. Multiliteracies are influencing the future of literacy teaching. One aspect of the pedagogy of multiliteracies is recruiting learners’ previous and current experiences as an integral part of the learning experience. This paper examines the implications of results from a project that examined student responses to a postmodern picture book, in particular, ways teachers might develop students’ self-knowledge about reading. It draws on Freebody and Luke’s Four Resources Model of Reading and recently developed models for teaching multiliteracies.

Performance Research in Rangeland Communities

In 2003, Bill Dunstone, John McCallum and Paul Makeham began a collaboration with researchers at the Centre for the Management of Arid Environments (CMAE) in Kalgoorlie, Western Australia. CMAE researchers are keen to develop 'people-oriented' strategies for implementing agricultural extension initiatives in their region. Traditional hierarchies of knowledge-transfer have impeded the 'connectedness' between community and researchers that gives meaning and relevance to useful practice (Ison and Russell, 2000). Our aim is to establish a partnership between the Live Events Research Network (LERN) and CMAE, investigating ways to link creative, performance-based research and practice with the scientific methodologies associated with natural resources management. This accords with recent work undertaken by Deborah Mills and Paul Brown, showing how community cultural development strategies enhance the implementation of policy concerned with community wellbeing. Mills and Brown 'adopted a concept of wellbeing which builds on a social and environmental view of health', and considered such themes as ecological sustainability, rural economic revitalisation, community strengthening, health and wellbeing (Mills, 2003). We propose that rangeland communities can creatively manage some of the challenges confronting them through performance-based projects which: - activate the stories through which a community enacts its sense of place; - facilitate live events in which the community enacts ownership of its culture and identity; - directly involve the community in the formulation of research issues

Demographic category membership and leadership in small groups : a social identity analysis

Developing the social identity theory of leadership (e.g., [Hogg, M. A. (2001). A social identity theory of leadership. Personality and Social Psychology Review, 5, 184–200]), an experiment (N=257) tested the hypothesis that as group members identify more strongly with their group (salience) their evaluations of leadership effectiveness become more strongly influenced by the extent to which their demographic stereotype-based impressions of their leader match the norm of the group (prototypicality). Participants, with more or less traditional gender attitudes (orientation), were members, under high or low group salience conditions (salience), of non-interactive laboratory groups that had “instrumental” or “expressive” group norms (norm), and a male or female leader (leader gender). As predicted, these four variables interacted significantly to affect perceptions of leadership effectiveness. Reconfiguration of the eight conditions formed by orientation, norm and leader gender produced a single prototypicality variable. Irrespective of participant gender, prototypical leaders were considered more effective in high then low salience groups, and in high salience groups prototypical leaders were more effective than less prototypical leaders. Alternative explanations based on status characteristics and role incongruity theory do not account well for the findings. Implications of these results for the glass ceiling effect and for a wider social identity analysis of the impact of demographic group membership on leadership in small groups are discussed.

How can we exploit mobile data to customise learning based on a student’s environmental surroundings?

User-Based intelligent systems are already commonplace in a student’s online digital life. Each time they browse, search, buy, join, comment, play, travel, upload, download, a system collects, analyses and processes data in an effort to customise content and further improve services. This panel session will explore how intelligent systems, particularly those that gather data from mobile devices, can offer new possibilities to assist in the delivery of customised, personal and engaging learning experiences. The value of intelligent systems for education lies in their ability to formulate authentic and complex learner profiles that bring together and systematically integrate a student’s personal world with a formal curriculum framework. As we well know, a mobile device can collect data relating to a student’s interests (gathered from search history, applications and communications), location, surroundings and proximity to others (GPS, Bluetooth). However, what has been less explored is the opportunity for a mobile device to map the movements and activities of a student from moment to moment and over time. This longitudinal data provides a holistic profile of a student, their state and surroundings. Analysing this data may allow us to identify patterns that reveal a student’s learning processes; when and where they work best and for how long. Through revealing a student’s state and surroundings outside of schools hour, this longitudinal data may also highlight opportunities to transform a student’s everyday world into an inventory for learning, punctuating their surroundings with learning recommendations. This would in turn lead to new ways to acknowledge and validate and foster informal learning, making it legitimate within a formal curriculum.
