Stories from the stone age

An exploration of the revolutionary period of prehistory that began when humans abandoned the nomadic hunting and gathering existence they had known for millennia to take up a completely new way of life the decisive move to farming and herding the ration of permanent settlements and the discovery of metals setting the stage for the arrival of the worldʼs first civilisation. Stores from the Stone Age ask some intriguing questions. Why did some of our ancestors never become farmers at all? Why do some still continue hunting and gathering despite their contact with farming people and advanced technologies? How and why did our paths become uniquely shaped after emerging as a species from a single genetic family in Africa? Based on extensive research, Stories from the Stone Age takes us on a journey where we get to live alongside our ancestors as they cross between the Old and the New Worlds and into Civilisation. The series utilises detailed re-enactments and short interviews with key archaeological experts.

How Hollywood projects foreign policy

The interactions between popular culture and public policy in general, and foreign policy in particular, have always been an important area of scholarly enquiry and popular interest. However with the end of the bipolar world system and the emergence of a single world superpower in the form of the United States of America, which is waging a War Against Terror, this nexus has become critical. This is especially true because of the almost Manichean tendency of the United States to see other countries in terms of "good" or "evil". Indeed President Bush himself has coined the term "The Axis of Evil" for states, which in a kinder age were simply referred to by his predecessors as being "Rogue States".

This book draws together elements from several academic disciplines - politics, international relations, psychology, film and cultural studies and examines US foreign policy toward the so-called "rogue states" and the products of the Hollywood film industry in relation to these states, which promises to make a significant contribution to our understanding of the 'soft power' that is popular culture.

Critical intellectual resources for praxis in physical education teacher education : the limits to rationality

This study focuses on the way four student-teachers engage with critical social discourses in a year-long physical education unit. The student-teachers were encouraged to examine and (re)construct their pedagogy through their interactions with critical discourses. Drawing on their personal theories and actions, the study examines the extent to which critical intellectual resources can provide pedagogical frames of reference that are 'practical and non-ideal'. Using a critical ethnographic methodology the students' interactions with critical social discourses are diagnosed across three levels. The first level is the case study presentations of each student's engagement with the critical intellectual resources and the extent to which they were able to understand and implement them. The second level involves an interpretation of the individual cases that is informed by Brian Fay's (1987) metatheoretical reconstruction of the critical social sciences. In the third stage of diagnosis the study focuses on retheorising critical aspirations for praxis pedagogy in physical education. Critical scholars within the physical education arena argue that critical praxis represents a pedagogy based on a 'world view' of the potential for agents to engage in a rational reordering of their qualitative existence. The essence of their claim is that critical discourses have the potential to facilitate a mode of praxis through which physical education teachers might better recognise, understand, critique and transform their values and practices. However, there is broad recognition that the translation of social-critical discourses into a pedagogic context is highly problematic. Interpretation of the study is provided by Fay's (1987) 'limits to change' thesis which recognises that critical aspirations must ultimately be adopted and implemented by real people in real settings. As a diagnostic frame of reference, Fay insists that a 'complete' critical theory [of physical education] be simultaneously scientific, critical, practical and non-ideal. In seeking to temper the "e; over-rationalistic"e; tendency of the critical project he recognises the historical, embedded, embodied and traditional nature of human existence Criticisms of critical theories of education traverse a number of philosophic perspectives. Recent post-structural criticisms of truth regimes, knowledge-power differentials, rationality and agency have seriously destabilised modernist justifications of the critical agenda. Critical theories of physical education have not been absolved of such criticism. A prominent element of this study is its promotion of a dialectical relationship between agency and structure to extend critical conceptualisations of physical education pedagogy. Through the mediation of structural determinism and self-determination this research proffers a means of practically advancing a critical praxis in physical education. The conclusion of this thesis outlines some broad recommendations pertaining to the introduction of social critical discourses in physical education teacher education.

Elastic behaviour in mechanical draw presses

This thesis explores the elastic behaviour of the mechanical double action press and draw die system commonly used to draw sheet metal components in the automotive industry. High process variability in production and excessive time spent in die try-out are significant problems in automotive stamping. It has previously been suggested that the elastic behaviour of the system may contribute to these problems. However, the mechanical principles that cause the press system to affect the forming process have not been documented in detail. Due to a poor understanding of these problems in industry, the elasticity of the press and tools is currently not considered during the die design. The aim of this work was to explore the physical principles of press system elasticity and determine the extent to which it contributes to problems in try-out and production. On the basis of this analysis methods were developed for controlling or accounting for problems during the design process. The application of frictional restraining force to the edges of the blank during forming depends on the distribution and magnitude of the clamping force between the binders surfaces of the draw die. This is an important control parameter for the deep drawing process. It has been demonstrated in this work that the elasticity of the press and draw die can affect clamping force in two ways. The response of the press system, to the forces produced in the press during forming, causes the magnitude of clamping force to change during the stroke. This was demonstrated using measured data from a production press. A simple linear elastic model of the press system was developed to illustrate a definite link between the measured force variation and the elasticity of the press and tools. The simple model was extended into a finite element model of the complete press system, which was used to control a forming simulation. It was demonstrated that stiffness variation within the system could influence the final strains in a drawn part. At the conclusion of this investigation a method is proposed for assessing the sensitivity of a part to clamping force variation in the press during die design. A means of reducing variation in the press through the addition of a simple linear spring element is also discussed. The second part of the work assessed the influence of tool structure on the distribution of frictional restraining forces to the blank. A forming simulation showed that tool stiffness affects the distribution of clamping pressure between the binders. This was also shown to affect the final strains in a drawn part. However, the most significant influence on restraining force was the tendency of the blank to increase in thickness between the binders during forming. Using a finite element approximation of the try-out process it was shown that the structure of the tool would also contribute to the problems currently experienced in try-out where uneven contact pressure distributions are addressed by manually adjusting the tool surfaces. Finally a generalised approach to designing draw die structures was developed. Simple analysis methods were combined with finite element based topology optimisation techniques to develop a set of basic design guidelines. The aim of the guidelines was to produce a structure with uniform stiffness response to a pressure applied at the binder surface. The work concludes with a recommendation for introducing the methods developed in this thesis into the standard production process.

Aesthetic experience and innovation in practice–led research

Within the context of ERA, this paper addresses the question of how we might provide practitioners with a framework for understanding creative arts research as the production of new knowledge. Drawing on the thought of Julia Kristeva, it examines the aesthetic underpinnings of discovery and the implications and significance of this for research training and the development of more effective pedagogies both within and beyond the university.
Kristeva’s work constitutes both an implicit and explicit critique of science allowing us to conceive of artistic research as an experiential and performative production of knowledge. As a mode of enquiry, artistic practice reveals the inextricable and necessary relationship between practice and theory, interpretation and making, art and life. This interrelationship underpins the aesthetic dimension of revolutionary practice and its production of unfamiliar or mutant forms of knowledge that is often difficult to grasp in terms of its capacity to engender social change and innovation. In the context of creative arts practice as research, the notion of experience-in-practice indicates that interpretation and analysis must fall to the practitioner-researcher, himself or herself, rather than to another person who has been external to the procedures of making, to trace the significant experiential, subjective and emergent processes involved in the production of the work that allows it to reveal the new. This is necessary if the generative and revolutionary impact of artistic research is to be fully understood in the wider research arena. In the final part of this paper, I will apply and illustrate these ideas through an analysis of a number of artistic research projects successfully completed in Australia.

Extreme response bias in measuring susceptibility to smoking.

Pierce, Choi, Gilpin, Farkas, and Berry (1998) were the first to claim that they could provide causal evidence that tobacco industry advertising and promotion caused adolescent smoking. This claim continues to significantly influence the theory and conceptualization of how youth react to tobacco marketing. The Pierce et al. (1998) methodology has been used by many researchers to establish the influence of tobacco marketing on adolescent smoking (Goldberg, 2003; NCI, 2006; Sargent, Dalton, & Beach, 2000). Pierce et al. (1998) selected respondents for only the second of their two survey longitudinal study because they chose the extreme-negative response. This choice could be the result of the tendency of some significant number of sample members exhibiting extreme-response bias. The results from an analysis of several questions from the original data used by Pierce et al. (1998) has suggested that there is a significant extreme-response style pattern in the Pierce et al. data. This unaccounted for bias in the responses of their sample was due to the procedure used by Pierce et al. (1998) in the selection of their respondents. The Pierce et al. (1998) sample selection procedure requires more research before the causal link can be claimed.

Understanding Marxism

Marxism as an intellectual movement has been one of the most important and fertile contributions to twentieth-century thought. No social theory or political philosophy today can be taken seriously unless it enters a dialogue, not just with the legacy of Marx, but also with the innovations and questions that spring from the movement that his work sparked, Marxism.

Marx provided a revolutionary set of ideas about freedom, politics and society. As social and political conditions changed and new intellectual challenges to Marx’s social philosophy arose, the Marxist theorists sought to update his social theory, rectify the sociological positions of historical materialism and respond to philosophical challenges with a Marxist reply. This book provides an accessible introduction to Marxism by explaining each of the key concepts of Marxist politics and social theory. The book is organized into three parts, which explore the successive waves of change within Marxist theory and places these in historical context, while the whole provides a clear and comprehensive account of Marxism as an intellectual system.

In vitro strain measurements in cerebral aneurysm models for cyber-physical diagnosis

Background: The development of new diagnostic technologies for cerebrovascular diseases requires an understanding of the mechanism behind the growth and rupture of cerebral aneurysms. To provide a comprehensive diagnosis and prognosis of this disease, it is desirable to evaluate wall shear stress, pressure, deformation and strain in the aneurysm region, based on information provided by medical imaging technologies. Methods: In this research, we propose a new cyber-physical system composed of in vitro dynamic strain experimental measurements and computational fluid dynamics (CFD) simulation for the diagnosis of cerebral aneurysms. A CFD simulation and a scaled-up membranous silicone model of a cerebral aneurysm were completed, based on patient-specific data recorded in August 2008. In vitro blood flow simulation was realized with the use of a specialized pump. A vision system was also developed to measure the strain at different regions on the model by way of pulsating blood flow circulating inside the model. Results: Experimental results show that distance and area strain maxima were larger near the aneurysm neck (0.042 and 0.052), followed by the aneurysm dome (0.023 and 0.04) and finally the main blood vessel section (0.01 and 0.014). These results were complemented by a CFD simulation for the addition of wall shear stress, oscillatory shear index and aneurysm formation index. Diagnosis results using imaging obtained in August 2008 are consistent with the monitored aneurysm growth in 2011. Conclusion: The presented study demonstrates a new experimental platform for measuring dynamic strain within cerebral aneurysms. This platform is also complemented by a CFD simulation for advanced diagnosis and prediction of the growth tendency of an aneurysm in endovascular surgery.

Polyalanine repeat polymorphism in RUNX2 is associated with site-specific fracture in post-menopausal femals

Runt related transcription factor 2 (RUNX2) is a key regulator of osteoblast differentiation. Several variations within the RUNX2 gene have been found to be associated with significant changes in BMD, which is a major risk factor for fracture. In this study we report that an 18 bp deletion within the polyalanine tract (17A>11A) of RUNX2 is significantly associated with fracture. Carriers of the 11A allele were found to be nearly twice as likely to have sustained fracture. Within the fracture category, there was a significant tendency of 11A carriers to present with fractures of distal radius and bones of intramembranous origin compared to bones of endochondral origin (p = 0.0001). In a population of random subjects, the 11A allele was associated with decreased levels of serum collagen cross links (CTx, p = 0.01), suggesting decreased bone turnover. The transactivation function of the 11A allele showed a minor quantitative decrease. Interestingly, we found no effect of the 11A allele on BMD at multiple skeletal sites. These findings suggest that the 11A allele is a biologically relevant polymorphism that influences serum CTx and confers enhanced fracture risk in a site-selective manner related to intramembranous bone ossification.

Integrating theory and practice in the pre-service teacher education practicum

This article reports on a study into student teachers’ perceptions about their professional development during practicum. Framed within a symbolic interactionist perspective, the study examined to what extent, and how effectively, one group of student teachers was able to integrate theory and practice during a three-week practicum in the first year of their degree. The context for this mixed methods study was a Master of Teaching, graduate-level entry programme in the Faculty of Education at an urban Australian university. Although there is a strong field of literature around the practicum in pre-service teacher education, there has been a limited focus on how student teachers themselves perceive their development during this learning period. Further, despite widespread and longstanding acknowledgement of the ‘gap’ between theory and practice in teacher education, there is still more to learn about how well the practicum enables an integration of these two dimensions of teacher preparation. In presenting three major findings of the study, this paper goes some way in addressing these shortcomings in the literature. First, participants in this study largely valued both the theoretical and practical components of their programme, which stands in contrast to the commonly identified tendency of the student teacher to privilege practice over theory. Second, opportunities to integrate theory and practice were varied, with many participants reporting the detrimental impact of an apparent lack of clarity around stakeholders’ roles and responsibilities. Third, participants overwhelmingly supported the notion of linking university coursework assessment to the practicum as a means of bridging the gap between, on the one hand, the university and the school and, on the other hand, theory and practice.

Australia's response to sexualised or sexually abusive behaviours in children and young people.

Responding to children and young people with sexualised or sexual offending behaviours presents significant challenges across the allied health, child protection, education and juvenile justice sectors. This report maps the specialised therapeutic services designed to effect positive behavioural change and thus divert young people with sexualised behaviours from the juvenile justice system. Accurate numbers on children with sexualised or sexual offending behaviours are difficult to determine. There are several factors contributing to this gap in understanding. These include entrenched ideals about children as inherently innocent, widespread ignorance about developmental sexuality, and the tendency of both young people and parents to deny or minimise incidents when they do occur.

In Australia, data on children with sexualised behaviours are not collected uniformly and nondisclosure contributes to what might be large numbers of offences going undetected. Mandatory reporting requirements apply where children display sexualised behaviours and are thought to be at risk of harm. Yet a general lack of knowledge as to what constitutes appropriate behaviour means that many may respond inappropriately to incidents of sexualised behaviours. This context of confusion, denial and non-disclosure creates a hidden population of children that continues to be at risk. Attention to redressing the contexts for non-disclosure is urgently required to ensure that children in need are provided with specialised therapeutic care.

This report presents qualitative data from interviews with specialised clinicians as well as submissions from service providers in both community and youth justice settings. In mapping the availability of therapeutic services, this report highlights a number of geographic and demographic gaps in service provision, including difficulties with eligibility criteria, referral pathways, funding arrangements and specialised workforce development. There are multiple challenges facing the tertiary services sector, yet the comprehensive provision of specialised services is just one part of the response required. This study emphasises the need for effective primary and secondary prevention to effect a reduction in the numbers of young people requiring counselling in the future. Consistent with the public health model, this report prioritises professional and community education strategies that would ultimately necessitate fewer tertiary services for young people and fewer places in juvenile detention centres.

Having sex with capitalism: parodic in-citation in the prose poem sequence

In his Spleen de Paris or Petits poèmes en prose [Little Prose Poems] Baudelaire (1869) forges an instrument of supple and radical potential, declaring the prose poem a ‘dangerous’ hybrid, which he wills elastic enough and staccato enough, to register the flows, jolts and distractions for the flâneur in the increasingly industrialised Paris. Here,by the mid-19th century, plate glass and gas lighting enable conspicuous consumption. Itis most strikingly the romantic-erotic and the relation between poet and his delicious, execrable wife, his inescapable, pitiless Muse (Baudelaire 1989: 177] that provides the nexus for radical questioning of the whole socio-political economy. Departing from Johnson’s Défigurations (1979) and using Irigaray’s (1984) hypothesis that the economy of sexual difference is the founding trope for the discursive and thus political economy of differences – of culture, ethnicity and class – this article first looks at theway Baudelaire activates the heterosexual relation as a site for social critique. It examines how Perec continues Baudelaire’s prose poetry experiment, offering, pre-May 1968, a revolutionary critique of desire by exploiting formal constraints to deconstruct still further the consumer subject of capitalism. It then investigates Brossard’s ‘hologrammatic’ challenge (1991) to patriarchal regimes of representation and the forms of desire they outlaw. Finally, it suggests how new work by Walwicz (2015)develops and displaces this radical inheritance.

Nearshore-offshore-basin species diversity and body size variation patterns in Late Permian (Changhsingian) brachiopods

 B.V. Body size is a fundamental and defining character of an organism, and its variation in space and time is generally considered to be a function of its biology and interactions with its living environment. A great deal of body size related ecological and evolutionary research has been undertaken, mostly in relation to extant animals. Among the many body size-related hypotheses proposed and tested, the size-bathymetry relationship is probably the least studied. In this study, we compiled a global body size dataset of Changhsingian (Late Permian, ca. 254. Ma-252. Ma) brachiopod species from low-latitude areas (30°S-30°N) and analyzed their species diversity and body size distribution patterns in relation to the nearshore-offshore-basin bathymetric gradient. The dataset contained 1768 brachiopod specimens in 435 species referred to 159 genera and 9 orders, from 135 occurrences (localities) of 18 different palaeogeographic regions. Treating the whole of the Changhsingian Stage as a single time slice, we divided the nearshore-offshore-basin bathymetric gradient into three broad depth-related environments: nearshore, offshore and basinal environments, and compared how the species diversity and body size varied along this large-scale bathymetric gradient.Here, we report an array of complex patterns. First, we found a clear overall inverse correlation between species diversity and water depth along the nearshore-offshore-basin gradient, with most species concentrating in the nearshore environment. Second, when the median sizes of all low-latitude brachiopod species from the three environments were compared, we found that there was no significant size difference between the nearshore and offshore environments, suggesting that neither the wave base nor the hydrostatic pressure exerts a critical influence on the body size of brachiopods. On the other hand, the median sizes of brachiopods from the nearshore environment and, to a lesser extent, the offshore environment were found to be significantly larger than that of basinal brachiopods. This trend of significant size reduction in basinal brachiopods mirrors the relative low species diversity in the basinal environment, and neither can be easily explained by the tendency of decreasing food availability towards deeper sea environments. Rather, both trends are consistent with the hypothesis of an expanding Oxygen Minimum Zone (OMZ) in the bathyal (slope to deepsea) environments, where hypoxic to anoxic conditions are considered to have severely restricted the diversification of benthos and favored the relative proliferation of small-sized brachiopods. Finally, a significant difference was also found between eurybathic and stenobathic species in their body size response to the nearshore-offshore-basin gradient, in that eurybathic species (species found in all three environments) did not tend to change their body size significantly according to depth, whereas stenobathic forms (species restricted to a single environment) exhibit a decline in body size towards the basinal environment. This pattern is interpreted to suggest that bathymetrically more tolerant species are less sensitive to depth control with respect to their body size change dynamics, in contrast to stenobathic species which tend to grow larger in shallower water depths.

Big data concepts, theories, and applications

Big data is one of the hottest research topics in science and technology communities, and it possesses a great potential in every sector for our society, such as climate, economy, health, social science, and so on. Big data is currently treated as data sets with sizes beyond the ability of commonly used software tools to capture, curate, and manage. We have tasted the power of big data in various applications, such as finance, business, health, and so on. However, big data is still in her infancy stage, which is evidenced by its vague definition, limited application, unsolved security and privacy barriers for pervasive implementation, and so forth. It is certain that we will face many unprecedented problems and challenges along the way of this unfolding revolutionary chapter of human history.
