This paper presents results from a survey of organizing forms in Australia's largest public companies between 2000 and 2004. The study sought to identify trends in forms of organizing and the extent to which the uptake of new forms led to a decrease in traditional forms of organizing. The analysis revealed changes across the organizational dimensions of structures, processes and boundaries. While Australian firms were clearly interested in exploring new forms of organizing, uptake was not universal, nor at the expense of traditional forms of organizing. An admixture of traditional and new, or dual, forms of organizing emerged as the preferred response to environmental turbulence. This paper employs and extends duality theory to explain the changes that occurred in Australian public companies over the four year period. Duality theory is operationalized in terms of five duality characteristics, which are employed to assess the composition and balance of traditional and new fOlms of organizing. The paper proposes that a dualities aware perspective offers a potential way forward in managing the balance between ostensibly contradictory forces of continuity and change.

We have determined the structure of the reduced form of the DsbA oxidoreductase from Vibrio cholerae. The reduced structure shows a high level of similarity to the crystal structure of the oxidized form and is typical of this class of enzyme containing a thioredoxin domain with an inserted α-helical domain. Proteolytic and thermal stability measurements show that the reduced form of DsbA is considerably more stable than the oxidized form. NMR relaxation data have been collected and analyzed using a model-free approach to probe the dynamics of the reduced and oxidized states of DsbA. Akaike's information criteria have been applied both in the selection of the model-free models and the diffusion tensors that describe the global motions of each redox form. Analysis of the dynamics reveals that the oxidized protein shows increased disorder on the pico- to nanosecond and micro- to millisecond timescale. Many significant changes in dynamics are located either close to the active site or at the insertion points between the domains. In addition, analysis of the diffusion data shows there is a clear difference in the degree of interdomain movement between oxidized and reduced DsbA with the oxidized form being the more rigid. Principal components analysis has been employed to indicate possible concerted movements in the DsbA structure, which suggests that the modeled interdomain motions affect the catalytic cleft of the enzyme. Taken together, these data provide compelling evidence of a role for dynamics in the catalytic cycle of DsbA.

There are many forms of memory in post-colonial Australia, and many kinds
of haunting. This paper investigates the poetry of contemporary Indigenous poets Sam Wagan Watson and Tony Birch, and reads the script of the Federal Government’s February 2008 Apology to the Stolen Generations, asking how and why the nation should be haunted – historically and imaginatively - into the future.

This qualitative research is an examination of the experience of learning within a mixed-mode teachers' professional development program. It examines how learning is affected by 'location' - geographic, institutional and personal, and how teaching may take location into account. Approaches to study, influences on learning and transformational learning are explored.

The study investigated trends in forms of organising in Australian companies between 2000 and 2004. Dual forms of organising emerged as the preferred response to environmental turbulence. A dualities aware perspective was proposed, offering the potential to maintain traditional accountability and control while adopting more flexible, responsive forms of organising.

There is a need for some alternative approaches to the way that undergraduate teacher education programs have traditionally been delivered. Our warrant for this assertion is derived, in the first instance, from the work of Aronowitz and Giroux who have argued that there are many different signs of a crisis of cognition within all levels of education. Twenty years later the conditions that they described seem even more entrenched. This paper argues for a fresh inquiry into the deeper logics of learning and teaching, by drawing primarily on the work of James, Dewey, Kierkegaard, Britzman and Mackay. There is also a brief inclusion of anecdotes from some initial applications of these theories into our own practice.

The overall purpose of this investigation was to examine the relationship between stress-related working conditions and three forms of employee performance behaviours: in-role behaviours, citizenship behaviours directed at other individuals and citizenship behaviours directed at the organization. The potentially stressful working conditions were based on the job strain model (incorporating job demands, job control and social support) as well as organizational justice theory. A sample of Australian-based police officers (n = 640) took part in this study and the data were collected via a mail-out survey. Multiple regression analyses were undertaken to assess both the strength and the nature of the relationships between the working conditions and employee performance and these analyses included tests for additive, interactional and curvilinear effects. The overall results indicated that a significant proportion of the explained variance in all three outcome measures was attributed to the additive effects of demand, control and support. The level of variance associated with the organizational justice dimensions was relatively small, although there were signs that specific dimensions of justice may provide unique insights into the relationship between job stressors and employee performance. The implications of these and other notable findings are discussed.

Via a wide range of case studies, this book examines new forms of resistance to social injustices in contemporary Western societies. Resistance requires agency, and agency is grounded in notions of the subject and subjectivity. How do people make sense of their subjectivity as they are constructed and reconstructed within relations of power? What kinds of subjectivities are needed to struggle against forms of dominance and claim recognition? The participants in the case studies are challenging forms of dominance and subordination grounded in class, race, culture, nationality, sexuality, religion, age, disability and other forms of social division. It is a premise of this book that new and/or reconstructed forms of subjectivity are required to challenge social relations of subordination and domination. Thus, the transformation of subjectivity as well as the restructuring of oppressive power relations is necessary to achieve social justice. By examining the construction of subjectivity of particular groups through an intersectional lens, the book aims to contribute to theoretical accounts of how subjects are constituted and how they can develop a critical distance from their positioning.

Engaging children in justifying, forming conjectures and generalising is critical to develop their mathematical reasoning. Previous studies have revealed limited opportunities for primary school children to justify their thinking, form conjectures and generalise in mathematics lessons. Forms of justification of Year3/4 children from three schools in Victoria, Australia will be examined. Evidence from children's written explanations and their verbal explanations captured in video recordings revealed that some children employed sophisticated mathamatical ideas in their justifications. The value of making children's reasoning explicit through written explanations and verbal communications is highlighted.

Too often, legal and sociopolitical scholars concerned with European policies anddecision-making procedures focus their efforts only on the official essence ofconventional opt-out forms of nonparticipation in the European integration process,such as those established in the Treaty of Lisbon. Yet, far from being just an internalmatter, the independentist instances which informed the Scottish referendum had asignificant impact on delicate issues of EU law, biopolitics, political anthropology,political theology, and foreign policy which deserve to be properly addressed. Thenecessity of conducting such an analysis is self-evident, and mainly related to thepossibility that the Scottish experience may be soon replicated, with different results,in the Italian regions of Venetia, Sardinia, and Lombardy, and in the Spanishcommunity of Catalonia. Delving into this dimension through Schmitt’s politicaldecisionism and adopting a comparative and interdisciplinary approach thattranscends the limits of pure positivistic and analytical lines of inquiry, this paperpresents a country’s choice to leave the EU or stop cooperating with it through thedirect opt-out mechanisms officially regulated in its Treaties, or through indirectforms of secessionism, in terms of an ‘exceptional’ act of sovereign will.
