This article is a study of the response of the Australian government under Robert Menzies to the emergence of the Afro-Asian movement in the mid-1950s, especially the element of the non-aligned nations, which culminated in the Bandung meeting of April 1955. Non-alignment and anti-colonialism posed direct threats to the Menzies government's plans for the defence of Southeast Asia and its foreign policy for the region. The study of the Australian response to the Bandung meeting reveals the different legacies which European imperialism left behind in Australia compared with its neighbours in south and east Asia.

Recognizing a class of movements as belonging to a "nominal" action category, such as walking, running, or throwing, is a fundamental human ability. Three experiments were undertaken to test the hypothesis that common ("prototypical") features of moving displays could be learned by observation. Participants viewed moving stick-figure displays resembling forearm flexion movements in the saggital plane. Four displays (presentation displays) were first presented in which one or more movement dimensions were combined with 2 respective cues: direction (up, down), speed (fast, slow), and extent (long, short). Eight test displays were then shown, and the observer indicated whether each test display was like or unlike those previously seen. The results showed that without corrective feedback, a single cue (e.g., up or down) could be correctly recognized, on average, with the proportion correct between .66 and .87. When two cues were manipulated (e.g., up and slow), recognition accuracy remained high, ranging between .72 and .89. Three-cue displays were also easily identified. These results provide the first empirical demonstration of action-prototype learning for categories of human action and show how apparently complex kinematic patterns can be categorized in terms of common features or cues. It was also shown that probability of correct recognition of kinematic properties was reduced when the set of 4 presentation displays were more variable with respect to their shared kinematic property, such as speed or amplitude. Finally, while not conclusive, the results (from 2 of the 3 experiments) did suggest that similarity (or "likeness") with respect to a common kinematic property (or properties) is more easily recognized than dissimilarity.

The article explores the ways knowledge and space are co-produced performatively through bodily movement in an examination of the Maltese megaliths the first complex stone structures in the world. It is argued that knowledge is best seen as spatialized narratives of human actions and objects as materialized forms of those spatial narratives. Rewriting our social and historical narratives so that the performativity of place, space and knowledge is restored opens new possibilities for rethinking the social and material order.

Consumer and patient advocacy groups (PAGs) are important participants in the politics of pharmaceuticals. Yet very little is known about the precise nature and extent of their influence. It is argued in this article that PAGs fulfil a mixed role within the health system at national and transnational levels, and that they are at times fully incorporated into economic and political power structures. Their frequent dependence on pharma industry funding is of particular concern. PAGs provide a means of direct industry interaction with the final customer, thereby partially bypassing and putting additional pressure on doctors and regulators. The article presents the case for research to establish a better empirical base for discussions about the role of PAGs within contemporary neo-liberal governance structures.

Many union leaders and observers of unionism in industrially advanced countries have recently argued for stronger links between unions and social movements but their arguments leave the nature of social movements underspecified. This article reviews the literature on social movements and argues in favour of a minimalist theory of the social actor rather than choose between American and European approaches to studying social movements. Both Melucci's European approach and McAdam, Tarrow, and Tilly's American approach to integrating the European and American schools of thought on social movements are inadequate to the task of specifying social-movement unionism. Hindess's minimalist theory of the social actor and articulated arenas of conflict offers a stronger approach to understanding social-movement unionism and appreciating its strategic pertinence in particular times and places. Two episodes of contention in Sweden illustrate the advantages of a minimalist theory of articulated social-movement unionism.

From a European perspective, the wide-ranging social, economic, and political effects of networked computers have generated tensions between 'new' social movements and the 'old' labour movement. From an American perspective on social movements, there is no such tension between old and new social movements. A study of social-movement unionism in Sweden offers a interesting means of testing this emerging American perspective against the European perspective because the labour movement has long been particularly effective and networked technology has been embraced whole-heartedly throughout all aspects of the society, the economy, and the polity. The paper introduces the contrasting European and American perspectives on social movements and presents examples of the practice of social-movement unionism among Swedish social democrats, unionists, and diverse local activists. These examples support conclusions that eschew utopian theories of 'cyberunionism' in favour of developing a theory of articulated unionism in which local unions branches articulate vertically with national and global union bodies, and articulate horizontally with social movements in other arenas of conflict.

Survey-based research explored the moderating effects of "exposure" to the Australian free-to-air telecast of Athens 2004 and "interest" in Olympic Games in developing behavioral intentions to visit Greece in the future. Differences were found between groups with low and high levels of exposure to the telecast, and also between groups with high levels of interest in the Olympic Games, but these were only marginal. When the combinatorial influences of these two variables were considered simultaneously, their effects were generally synergistic. The article calls for further research on this area of mega-events, as the results, while of significance, provide food to continue the broader debate on the role of mega-events in developing tourism to their host destinations after their staging.

Traditional studies of long-term change in trade union structure have predominantly focused on aggregate trends in union merger activity, in constructing explanations of change. This paper argues that our understanding of structural change in the Australian trade union movement would be better served by a structural events approach that examines the incidence of union formations, dissolutions, and breakaways, in addition to that of union mergers. In doing so, it outlines how these structural events can be identified and measured, and presents the preliminary findings from the methods application.

Recent studies show that children with developmental coordination disorder (DCD) have difficulties in generating an accurate visuospatial representation of an intended action, which are shown by deficits in motor imagery. This study sought to test this hypothesis further using a mental rotation paradigm. It was predicted that children with DCD would not conform to the typical pattern of responding when required to imagine movement of their limbs. Participants included 16 children with DCD and 18 control children; mean age for the DCD group was 10 years 4 months, and for controls 10 years. The task required children to judge the handedness of single-hand images that were presented at angles between 0° and 180° at 45° intervals in either direction. Results were broadly consistent with the hypothesis above. Responses of the control children conformed to the typical pattern of mental rotation: a moderate trade-off between response time and angle of rotation. The response pattern for the DCD group was less typical, with a small trade-off function. Response accuracy did not differ between groups. It was suggested that children with DCD, unlike controls, do not automatically enlist motor imagery when performing mental rotation, but rely on an alternative object-based strategy that preserves speed and accuracy. This occurs because these children manifest a reduced ability to make imagined transformations from an egocentric or first-person perspective.

Interaction of Lamb waves with structural damage can lead to wave mode conversion. In this study, the shear horizontal (SH) wave, from the mode conversion of the fundamental symmetric Lamb wave (S0), was used for quantitative identification of delamination in composite beams, based on advanced signal processing using an inverse approach. SH wave propagation under various delamination conditions in CF/EP beams made of orthotropic plain woven fabrics was simulated, and signal characteristics were extracted in terms of the concept of digital damage fingerprints (DDF). With the aid of an artificial neural algorithm, the relation between the DDF of delamination-scattered SH mode and damage parameters was calibrated, whereby the occurrence, location and size of delamination in the composite beams were assessed. The approach was experimentally validated, and the results demonstrate the effectiveness of SH mode for quantitative damage evaluation of composite structures.
