Seminal reports into higher education in Australia and overseas have recognised negotiation as an essential skill of a practising lawyer and have recommended that all law schools include instruction in negotiation theory and practice in their curricula. Effective negotiation training includes the elements of instruction, modelling, practice and feedback. Ideally such training takes place in the context of small groups. However, this does not necessarily mean that negotiation cannot be taught effectively in the context of large groups. This paper discusses two related blended learning environments that provide instruction in negotiation theory and practice as part of the graduate capabilities program of the undergraduate law degree in the School of Law at the Queensland University of Technology in Brisbane, Australia. Air Gondwana, which forms part of the curriculum of the two first year Contract Law subjects, and Mosswood Manor, which forms part of the curriculum of the second year Trusts subject, utilise a common narrative concerning the family of a wealthy industrialist to facilitate learning of negotiation skills. The programs both combine online and in-class components, the online components utilising machinima (computer graphics created without the need for professional software) to depict the narrative. This strategy has enabled the creation of effective, engaging and challenging learning experiences for large cohorts of students studying by different modes (full-time, part-time and distance external). The use of a common narrative, including the same characters and settings, in the two programs also provides a familiar environment in which students advance their learning from one level of attainment to the next.

This chapter outlines the reasons why discourse analysis is an important dimension of critical social work practice. It brings to the forefront the very significant new contributions that sociologists focusing on the politics of recognition and redistribution, such as Nancy Fraser and Axel Honneth, can make in casting a "new politics of critical social work". In making this case, it begins by discussing some key developments in discourse theory and analysis within the social sciences and how they relate to the normative concerns of social work, specifically social justice and its multiple interpretations. Developing an appropriate analytical framework for social work practice can be difficult because there are conflicting and overlapping definitions of discourse formulated from various theoretical and disciplinary standpoints (Fairclough, 1992; Macdonnell, 1991). There are many different accounts of discourse that have developed in the social sciences, which is partly a result of recent interest in discourse theory among a wide range of academic disciplines. Whether language has assumed more of a central focus as a result of increased academic interest, or whether there has been an increase in the social importance of language in the operations of power is open to question...

Mobility across space is an exemplary characteristic of the global era and an important aspect of the cultural experience of many people in advanced industrialised nations. Mobility evokes powerful images that effectively counter any illusion of stationary life and provide a break from the insularity of the local and parochial. High levels of mobility are simultaneously a fact, a necessity and a cultural aspiration. In recent times, debates about mobility in social theory have considered the relationship between mobility and cosmopolitan culture and identities (Hannerz, 1990, Urry, 1990, 2000, Beck, 2006). Against this backdrop, this paper also draws on some of the more recent discussions about the emergence of globalised and cosmopolitan identities among young people (Beck and Beck-Gernsheim, 2009). Using data from a longitudinal study of young people in Queensland, this paper provides an insight into young people’s aspirations about future mobility. The data affirm Skeggs’ (2004) comment that mobility is an unequal resource, and demonstrate that aspirations of future mobility reflect numerous social, economic and cultural realities of young people’s lives. This inevitably leads us to problematise the established, and often abstract, nexus between cosmopolitanism and mobility in contemporary debates about cosmopolitanism.

Trust is widely recognized as one of the key qualities that a successful leader needs to bring about change within his/her organization. Literature has also shown that trust plays a pivotal role in effective school leadership. However, little research has been undertaken to identify specific actions of a transformational school leader enabling him/her to develop purposeful relationships of trust with his/her staff and Chair of the school’s governing body. Using a theoretical framework of transformational leadership in the context of the independent schooling sector in Australia, a multicase study of four highly trusted, transformational school leaders revealed 10 key trust building practices in the Head–staff dyad and three practices in the Head–Chair dyad. These practices were independent of the leader’s personal attributes. The study also revealed an inextricable link between trust and transformational leadership.

Algebraic immunity AI(f) defined for a boolean function f measures the resistance of the function against algebraic attacks. Currently known algorithms for computing the optimal annihilator of f and AI(f) are inefficient. This work consists of two parts. In the first part, we extend the concept of algebraic immunity. In particular, we argue that a function f may be replaced by another boolean function f^c called the algebraic complement of f. This motivates us to examine AI(f ^c ). We define the extended algebraic immunity of f as AI *(f)= min {AI(f), AI(f^c )}. We prove that 0≤AI(f)–AI *(f)≤1. Since AI(f)–AI *(f)= 1 holds for a large number of cases, the difference between AI(f) and AI *(f) cannot be ignored in algebraic attacks. In the second part, we link boolean functions to hypergraphs so that we can apply known results in hypergraph theory to boolean functions. This not only allows us to find annihilators in a fast and simple way but also provides a good estimation of the upper bound on AI *(f).

As a concept, the magic circle is in reality just 4 years old. Whilst often accredited to Johan Huizinga (1955), the modern usage of term in truth belongs to Katie Salen and Eric Zimmerman. It became in academia following the publication of “Rules of Play” in 2003. Because of the terminologyused, it carries with it unhelpful preconceptions that the game world, or play-space, excludes reality. In this paper, I argue that Salen and Zimmerman (2003) have taken a term used as an example, and applied a meaning to it that was never intended, based primarily upon definitions given by other authors, namely Apter (1991) and Sniderman (n.d.). I further argue that the definition itself contains a logical fallacy, which has prevented the full understanding of the definition in later work. Through a study of the literature in Game Theory, and examples of possible issues which could arise in contemporary games, I suggest that the emotions of the play experience continue beyond the play space, and that emotions from the “real world” enter it with the participants. I consider a reprise of the Stanley Milgram Obedience Experiment (2006), and what that tells us about human emotions and the effect that events taking place in a virtual environment can have upon them. I evaluate the opinion espoused by some authors of there being different magic circles for different players, and assert that this is not a useful approach to take when studying games, because it prevents the analysis of a game as a single entity. Furthermore I consider the reasons given by other authors for the existence of the Magic Circle, and I assert that the term “Magic Circle” should be discarded, that it has no relevance to contemporary games, and indeed it acts as a hindrance to the design and study of games. I conclude that the play space which it claims to protect from the courts and other governmental authorities would be better served by the existing concepts of intent, consent, and commonly accepted principles associated with international travel.

Existing planning theories tend to be limited in their analytical scope and often fail to account for the impact of many interactions between the multitudes of stakeholders involved in strategic planning processes. Although many theorists rejected structural–functional approaches from the 1970s, this article argues that many of structural–functional concepts remain relevant and useful to planning practitioners. In fact, structural–functional approaches are highly useful and practical when used as a foundation for systemic analysis of real-world, multi-layered, complex planning systems to support evidence-based governance reform. Such approaches provide a logical and systematic approach to the analysis of the wider governance of strategic planning systems that is grounded in systems theory and complementary to existing theories of complexity and planning. While we do not propose its use as a grand theory of planning, this article discusses how structural–functional concepts and approaches might be applied to underpin a practical analysis of the complex decision-making arrangements that drive planning practice, and to provide the evidence needed to target reform of poorly performing arrangements.

IN MANY FACTORIES, the feed chute of the first mill is operated with a high chute level for the purpose of maximising the cane rate through the mill. There is a trend towards trying to control chute level within a small control range near the top of a chute that can result in rapid changes in cane feeding rate to maintain the chute level set point. This paper reviews the theory that predicts higher cane rate with higher chute level and discusses the main weakness in the theory that it does not consider the beneficial effect on capacity of cane falling from the top of the chute to the top surface of the cane mat. An extension to the chute theory model is described that predicts higher capacity with lower chute level because of the effect of the falling cane. The original model and this extended model are believed to be the upper and lower limits to the true effect. The paper reports an experiment that measured the real effect of chute level on capacity and finds that increasing chute level does lead to higher capacity but that the trend is only about one-third as strong as the original theory predicted. The paper questions whether the benefits of slightly greater capacity outweigh the costs of operating with the small control range near the top of the chute.

Drawing from experience internationally, on recent and important developments in regulatory theory, and upon models and approaches constructed during the author's empirical research, this book addresses the question: how can law influence the internal self-regulation of organisations in order to make them more responsive to occupational health and safety concerns? In this context, it is argued that Occupational Health and Safety management systems have the potential to stimulate models of self-organisation within firms in such a way as to make them self-reflective and to encourage informal self-critical reflection about their occupational health and safety performance.

In this chapter, we provide an overview of the concept of critical literacy and outline how it can inform classroom practice. This is no simple task, because there is no singular, normative version of critical literacy. Rather, it is a concept that has been shaped by various theoretical paradigms over the years and formulated in practice in ways that are deeply contextualized and specifically situated. This means that providing a historical overview of its development is well nigh impossible. Nevertheless, we will, in this introductory session, trace critical literacy's origins in critical theory and pedagogy, and offer a brief review of other theoretical influences on its development

This paper addresses the gap in economic theory underlying the multidimensional concept of food security and observed data by deriving a composite food security index using the latent class model. The link between poverty and food security is then examined using the new food security index and the robustness of the link is compared with two unidimensional measures often used in the literature. Using Vietnam as a case study, it was found that a weak link exists for the rural but not for the urban composite food security index. The unidimensional measures on the other hand show a strong link in both the rural and urban regions. The results on the link are also different and mixed when two poverty types given by persistent and transient poverty are considered. These findings have important policy implications for a targeted approach to addressing food security.

This paper reflects on how relevance has been invoked as a curricular principle, both by students and teachers, in curriculum documents and in curriculum theory, to explore its variously conceived parameters and conditions. By posing the questions ‘relevant to whom?’, ‘relevant to what?’, ‘relevant how?’ and ‘relevant when?’ this paper exposes relevance as both a curricular virtue and a curricular constraint. It draws on an empirical project undertaken in the prevocational curriculum offered in Australia’s recently extended compulsory schooling for students in non-academic pathways. Data vignettes offer windows into two settings to exemplify the different ways relevance can be interpreted, stretched or contested. Using Bernstein’s distinction between vertical and horizontal discourses and knowledge structures, the analysis identifies what is gained and what is lost when relevance, variously defined, serves as a principle for curricular selection.
