Teaching and live performances : applied theatre in universities and schools

This article compares the classroom process of school teachers and university lecturers to the activity of theatrical performance. In doing so, it probes the potential of live performance as an educational instrument. It concludes by tracing some of the history of applications of theatre to education, from the time of Brecht to the present day.

Financial crisis, Social pathologies and 'generalised perversion' : questioning Zizek's diagnosis of the times

Slavoj Zizek's work has been highly influential in the formulation of an emerging consensus among Lacanian social researchers, that we live in a society of generalised perversion whose initial fruits are the corrosion of democracy and the recent financial crisis. This position rests upon a notion of modern subjectivity that connects ‘commodity fetishism’ with clinical perversion in a pathological configuration, so that social theoretical identification of crisis tendencies, evaluative language about moral problems and diagnostic categories from the Lacanian clinic can be combined in a single figure. In this article, we question the series of conceptual links that constitute this position, tracing them from Zizek’s critique in his short work on the global financial crisis and his broader restatement of this analysis in the recent Living in the End Times, through the moment of his announcement of the notion of ‘generalised perversion’ in The Ticklish Subject, all the way back to fundamental propositions outlined in his earliest work. Our argument progresses through three claims. First, we show in the evolution of this position that it leads Zizek to equivocate in his diagnosis of contemporary society between two mutually exclusive categories (‘psychosis’ and ‘perversion’), indicating an antinomy in his work that is resolved in favour of ‘generalised perversion’ on empirical, not logical, grounds. Secondly, we offer a critical resolution of the antinomy through a critique of what we argue is Zizek’s mistaken over-extension of psychoanalytic reason beyond its legitimate scope of application. Finally, we point to some of the political implications of the way that Zizek speculatively resolves his logical difficulties, by analysing the consequences of his claim that generalised social perversion - the problem to be solved - involves a dethroning of the communal ego ideal. A communitarian streak, implicit in the potential conflation of moral denunciation with psychoanalytic diagnosis that the rhetoric of ‘perversion’ invokes, runs through Zizek’s work on capitalism, we propose in conclusion.

An approximate numerical technique for characterizing optical pulse propagation in inhomogeneous biological tissue

An approximate numerical technique for modeling optical pulse propagation through weakly scattering biological tissue is developed by solving the photon transport equation in biological tissue that includes varying refractive index and varying scattering/absorption coefficients. The proposed technique involves first tracing the ray paths defined by the refractive index profile of the medium by solving the eikonal equation using a Runge-Kutta integration algorithm. The photon transport equation is solved only along these ray paths, minimizing the overall computational burden of the resulting algorithm. The main advantage of the current algorithm is that it enables to discretise the pulse propagation space adaptively by taking optical depth into account. Therefore, computational efficiency can be increased without compromising the accuracy of the algorithm.

A new watermarking protocol against conspiracy

A trusted third party introduced in watermarking protocols would decrease the security and affect the implementation of the protocols. In this paper, a new watermarking protocol with an un trusted third party (UTTP) was proposed. Based on the idea of all-o>nothing disclosure of secret (ANDOS), all of the buyer, the seller and the third party didn't know the exact watermark, which was embedded in a digital content for tracing piracy. The proposed protocol pro vided mechanisms to trace piracy and protect customer's right, fn addition, the problem that a seller colluded with UTTP to frame the buyer, namely, the conspiracy problem, could be avoided.

Circle: orbital commutation

In exercising vision we employ strategies to perceive space and to distinguish the objects of attention. Some processes however remain invisible to us; how we process binocular vision; and how we resolve vision in motion. This work images invisible motion perspective. Revelation of invisible mechanisms of vision exposes the haptic qualities of sight and their contribution to proprioception and ʻaffordanceʼ. Figuring the ʻvortex of visionʼ also releases symbolic and metaphoric potentials. This innovative outcome of practical research develops imagery which depicts relative movement in space using the principles of motion perspective (Herschel) and optic flow (J. J. Gibson); the locative awareness of volumes in space through the dimensions of time and space presented in 2D imagery. The mural scale (3.5 metres) work presented in 'Circle', a group show of work around the idea of 'the circle' curated by Melinda Capp is derived from a large production of digital photographs made in the London Underground. In this work, the circle is associated with the orbit of the commuter which bends around the twin poles of home and employment, work and rest, circulating in an ellipse around the Ideal Life. Each traveller's path is a braid woven through gyrations of force and resistance. Optic flow, emulated with the rotating lens, tracing the moving subject, makes this visible.

Migrant Houses in the village Zavoj, Republic of Macedonia, 1988-2010

The focus of this data is on the transformation of the village Zavoj in the Republic of Macedonia, due to emigration from the village, recorded through the architectural changes to the houses in the village. The village had become by default a place for the accommodation of elderly people who did not want to join their offspring abroad in the cities of immigration, or in the fringe suburbs of nearby towns.

The data documents the ‘material history’ of the houses, and constitutes a longitudinal research project tracing the transformation of the architectural fabric of the village since 1988. It includes visual documentation such as photographs and drawings, and includes the houses as HOUSE-STATES as follows:

House-Traditional: Vernacular architecture still in use and maintained as a dwelling.
House-Construction: Buildings that are still being constructed, the house as ongoing construction site.
House-Fragment: An eMigrant house-fragment is juxtaposed with the vernacular dwelling. Typical and affordable techniques of single brick cavity and reinforced concrete structure are evident in the new fragment.
House-Closed: Many new houses have only one door and one window, height, size and volume are minimal; and are closed a lot of the time.
House-Ruin: Vernacular traditional dwellings that are deteriorating. Traditional vernacular dwellings are rarely renovated, reconstructed or repaired.

The data is complemented by several field-work methods including participant observation, interviews, documentation of the village as a totality, recording of oral histories and myths, festivities, and archival statistical research about the vicinity.

This dataset comprises photographic documentation, sketch/drawing documentation, digital interview recordings, and interview notes.

Quick fixes, drug culture and management culture : excellence and ecstasy, BPR and Brown

This paper critiques the prescriptions of management gurus by charting parallels between management culture and drug culture over the last two decades. I argue that the ‘quick fixes’ peddled by gurus mirror the illicit drug fix of choice popularised in the same era. I suggest that, in terms of the specific nature of their promised highs, Excellence mirrored Ecstasy, and Business Process Reengineering mirrored Heroin. By tracing resonance with drug fixes, I introduce another way to understand why particular corporate fixes are found so attractive, locating this in patterns of addiction and in the gurus’ ability to exploit wider shared cultural contexts. The paper ends by suggesting that the comparison with the world of illicit drugs has lessons not only for our understandings of management and management gurus, but also for critical management academics engagement with both the gurus and our wider audiences.

Urban ecologies at the edge : a case study

This paper discusses some central theoretical and methodological constructs in the field of urban ecologies, identifies research gaps in the field, and uses the Victoria Laboratory of Urban Ecologies (VALUE) as a case study illustrating possible directions of future urban ecologies research. It begins by tracing the theoretical roots of urban ecologies before reviewing contemporary urban ecologies studies throughout the world. Two critical gaps in urban ecologies research are identified, suggesting opportunities for future studies. The paper then introduces the research teams and projects of VALUE – a research centre hosted by the School of Architecture and Building at Deakin University. The paper concludes that the research activities in VALUE are at the edge of urban ecologies research due to the interdisciplinary nature of collaboration in and between project teams, which have thus been able to address gaps in urban ecologies research and make important contributions to the field.

Dorsal and ventral medullary catecholamine cell groups contribute differentially to systemic interleukin-1beta-induced hypothalamic pituitary adrenal axis responses

Medial parvocellular paraventricular corticotropin-releasing hormone (mPVN CRH) cells are critical in generating hypothalamic-pituitary-adrenal (HPA) axis responses to systemic interleukin-1beta (IL-1beta). However, although it is understood that catecholamine inputs are important in initiating mPVN CRH cell responses to IL-1beta, the contributions of distinct brainstem catecholamine cell groups are not known. We examined the role of nucleus tractus solitarius (NTS) and ventrolateral medulla (VLM) catecholamine cells in the activation of mPVN CRH, hypothalamic oxytocin (OT) and central amygdala cells in response to IL-1beta (1 microg/kg, i.a.). Immunolabelling for the expression of c-fos was used as a marker of neuronal activation in combination with appropriate cytoplasmic phenotypic markers. First we confirmed that PVN 6-hydroxydopamine lesions, which selectively depleted catecholaminergic terminals, significantly reduced IL-1beta-induced mPVN CRH cell activation. The contribution of VLM (A1/C1 cells) versus NTS (A2 cells) catecholamine cells to mPVN CRH cell responses was then examined by placing ibotenic acid lesions in either the VLM or NTS. The precise positioning of these lesions was guided by prior retrograde tracing studies in which we mapped the location of IL-1beta-activated VLM and NTS cells that project to the mPVN. Both VLM and NTS lesions reduced the mPVN CRH and OT cell responses to IL-1beta. Unlike VLM lesions, NTS lesions also suppressed the recruitment of central amygdala neurons. These studies provide novel evidence that both the NTS and VLM catecholamine cells have important, but differential, contributions to the generation of IL-1beta-induced HPA axis responses.

Evidence that the bed nucleus of the stria terminalis contributes to the modulation of hypophysiotropic corticotropin-releasing factor cell responses to systemic interleukin-1β

Systemic infection activates the hypothalamic-pituitary-adrenal (HPA) axis, and brainstem catecholamine cells have been shown to contribute to this response. However, recent work also suggests an important role for the central amygdala (CeA). Because direct connections between the CeA and the hypothalamic apex of the HPA axis are minimal, the present study investigated whether the bed nucleus of the stria terminalis (BNST) might act as a relay between them. This was done by using an animal model of acute systemic infection involving intravascular delivery of the proinflammatory cytokine interleukin-1β (IL-1β, 1 μg/kg). Unilateral ibotenic acid lesions encompassing the ventral BNST significantly reduced both IL-1β-induced increases in Fos immunoreactivity in corticotropin-releasing factor (CRF) cells of the hypothalamic paraventricular nucleus (PVN) and corresponding increases in adrenocorticotropic hormone (ACTH) secretion. Similar lesions had no effect on CRF cell responses to physical restraint, suggesting that the effects of BNST lesions were not due to a nonspecific effect on stress responses. In further studies, we examined the functional connections between PVN, BNST, and CeA by combining retrograde tracing with mapping of IL-1β-induced increases in Fos in BNST and CeA cells. In the case of the BNST, these studies showed that systemic IL-1β administration recruits ventral BNST cells that project directly to the PVN. In the case of the CeA, the results obtained were consistent with an arrangement whereby lateral CeA cells recruited by systemic IL-1β could regulate the activity of medial CeA cells projecting directly to the BNST. In conclusion, the present findings are consistent with the hypothesis that the BNST acts as a relay between the CeA and PVN, thereby contributing to CeA modulation of hypophysiotropic CRF cell responses to systemic administration of IL-1β.

Medial prefrontal cortex control of the paraventricular hypothalamic nucleus response to psychological stress : possible role of the bed nucleus of the stria terminalis

The medial prefrontal cortex (mPFC) has been strongly implicated in control of the paraventricular nucleus of the hypothalamus (PVN) response to stress. Because of the paucity of direct projections from the mPFC to the PVN, we sought to investigate possible brain regions that might act as a relay between the two during psychological stress. Bilateral ibotenic acid lesions of the rat mPFC enhanced the number of Fos-immunoreactive cells seen in the PVN after exposure to the psychological stressor, air puff. Altered neuronal recruitment was seen in only one of the candidate relay populations examined, the ventral bed nucleus of the stria terminalis (vBNST). Furthermore, bilateral ibotenic acid lesions of the BNST caused a significant attenuation of the PVN response to air puff. To better characterize the structural relationships between the mPFC and PVN, retrograde tracing studies were conducted examining Fos expression in cells retrogradely labeled with cholera toxin b subunit (CTb) from the PVN and the BNST. Results obtained were consistent with an important role for both the mPFC and BNST in the mpPVN CRF cell response to air puff. We suggest a set of connections whereby a direct PVN projection from the ipsilateral vBNST is involved in the mpPVN response to air puff and this may, in turn, be modulated by an indirect projection from the mPFC to the BNST.

Medial prefrontal cortex suppression of the hypothalamic–pituitary–adrenal axis response to a physical stressor, systemic delivery of interleukin-1β

Previous studies have shown that the medial prefrontal cortex can suppress the hypothalamic–pituitary–adrenal axis response to stress. However, this effect appears to vary with the type of stressor. Furthermore, the absence of direct projections between the medial prefrontal cortex and corticotropin-releasing factor cells at the apex of the hypothalamic–pituitary–adrenal axis suggest that other brain regions must act as a relay when this inhibitory mechanism is activated. In the present study, we first established that electrolytic lesions involving the prelimbic and infralimbic medial prefrontal cortex increased plasma adrenocorticotropic hormone levels seen in response to a physical stressor, the systemic delivery of interleukin-1β. However, medial prefrontal cortex lesions did not alter plasma adrenocorticotropic hormone levels seen in response to a psychological stressor, noise. To identify brain regions that might mediate the effect of medial prefrontal cortex lesions on hypothalamic–pituitary–adrenal axis responses to systemic interleukin-1β, we next mapped the effects of similar lesions on interleukin-1β-induced Fos expression in regions previously shown to regulate the hypothalamic–pituitary–adrenal axis response to this stressor. It was found that medial prefrontal cortex lesions reduced the number of Fos-positive cells in the ventral aspect of the bed nucleus of the stria terminalis. However, the final experiment, which involved combining retrograde tracing with Fos immunolabelling, revealed that bed nucleus of the stria terminalis-projecting medial prefrontal cortex neurons were largely separate from medial prefrontal cortex neurons recruited by systemic interleukin-1β, an outcome that is difficult to reconcile with a simple medial prefrontal cortex–bed nucleus of the stria terminalis–corticotropin-releasing factor cell control circuit.

Festivals, artists and entrepreneurialism : the role of the Adelaide Fringe Festival

This paper addresses the role of the Adelaide Fringe Festival in facilitating entrepreneurialism amongst participating artists. Tracing the discursive development of the notion of the entrepreneur, the paper identifies how entrepreneurialism has been taken up by the discourses of the creative industries. While we note that entrepreneurialism is a key strategy within the creative industries framework, it would appear for artists the concept does not necessarily connote the achievement of commercial outcomes. The paper argues that these cultural entrepreneurs are defined by self-reliance, the focus on the development of their craft, and the cultural value of their work.

Early Connections : reflections on the canonical lineage of Southeast Asian temples

Temples were constructed across Southeast Asia following the spread of Brahmanic/Hindu culture between the fifth to eight centuries CE. Epigraphic evidence, architectural and stylistic similarities between temples in the region are strongly indicative of historic cross cultural links between the traditions. This paper presents the findings of a research project that pieces together fragments of evidence from early temple sites in Southeast Asia to establish the linkages between the Southeast Asian temple building traditions. The focus of the paper is on tracing the canonical connections between these traditions through an examination of temple sites in Cambodia and Java respectively. The legacy of this ancient diasporic movement remains celebrated today in the admiration of Southeast Asian monuments such as Angkor Wat and Prambanan. However this architecture evolved over time through a process of long experimentation with philosophies, world-views, and methods. . In order to permit a deeper examination of canonical connections, the authors use methods such as photogrammetry, digital and physical models to reconstruct the architectural forms. A detailed analysis of the canonical geometry and compositional form of these temples is undertaken with reference to Indic texts and temples. Comparing the relationships between cosmology, geometry and physical form in this earlier sites with both Indian and developed Southeast Asian models, it is intended that its generative role within Southeast Asian architectural historiography can be clarified and more fully celebrated.

Association between the oxytocin receptor gene and amygdalar volume in healthy adults

Background: Recent studies have suggested that oxytocin affects social cognition and behavior mediated by the oxytocin receptor (OXTR) in amygdala in humans as well as in experimental animals. Genetic studies have revealed a link between the OXTR gene and the susceptibility to autism spectrum disorders (ASD), especially in the social dysfunctional feature of ASD.

Methods: We examined the relationship between amygdala volume measured with manual tracing methodology and seven single nucleotide polymorphisms and one haplotype-block in OXTR, which were previously reported to be associated with ASD, in 208 socially intact Japanese adults with no neuropsychiatric history or current diagnosis.

Results: The rs2254298A allele of OXTR was significantly associated with larger bilateral amygdala volume. The rs2254298A allele effect on amygdala volume varied in proportion to the dose of this allele. The larger the number of rs2254298A alleles an individual had, the larger their amygdala volume. Such an association was not observed with hippocampal volume or with global brain volumes, including whole gray, white matter, and cerebrospinal-fluid space. Furthermore, two three–single nucleotide polymorphism haplotypes, including rs2254298G allele, showed significant associations with the smaller bilateral amygdala volume.

Conclusions: The present results suggest that OXTR might be associated with the susceptibility to ASD, especially in its aspects of social interaction and communication mediated by a modulation of amygdala development, one of the most distributed brain regions with high density of OXTR. Furthermore, amygdala volume measured with magnetic resonance imaging could be a useful intermediate phenotype to uncover the complex link between OXTR and social dysfunction in ASD.
