The outward gaze and the inward gaze : houses of Italian and Chinese migrants in Melbourne

Not much has been said on the role of the architectural form of housing in the process of migrants’ settlement in the literature. This paper looks at this question through an exploration of the ‘outward gaze’ against the ‘inward gaze’. The outward gaze allows the investigation of exteriors of houses - assumed to be of Italian migrants - by looking at them only from the street, while the ‘inward gaze’ allows the investigation of the interiors of the house as well. In addition to housing exteriors explored in the streets of Melbourne, one Chinese migrant house was examined first through the outward gaze, as seen from the outside of the house by passer-bys, and then by the inward gaze, as seen only by household members and their guests. It is argued that ethnic representations described in the literature are only the visible side of the story, and that there is a lot more that is hidden from the public eye that can be exposed only by the inward gaze. Nevertheless, these unseen representations are vital to the settlement process and are often crucial to its success.

Tourist snapshot : the mediating gaze of the Sydney Opera House

There has already been much scholarly work produced about the Sydney Opera House, discussing the production of its architecture, historical and political context, and its symbolic meaning to Sydney. However little scholarly attention has been paid to the way this building is represented through tourist practices of photography. The essay attempts to bring an architectural perspective to the study of this tourist practice, which is usually addressed from the disciplines of cultural geography, sociology and anthropology. The essay considers the above questions by the analysis of some 300 images sourced from the photo sharing website Flickr (www.flickr.com). It draws on John Urry's notion of the 'tourist gaze' which describes how places are structured and regulated by the visual. The essay then uses Jonas Larsen's work, which position tourist photography as a performance of social relations to argue that the activity of photographing the Sydney Opera House is more than a ritual of consumption, and can be seen as an embodied performance located at the intersection of space, experience and image.

Linking physiology with behaviour: Functional specialisation of the visual field is reflected in gaze patterns during visual search

Based on neurophysiological findings and a grid to score binocular visual field function, two hypotheses concerning the spatial distribution of fixations during visual search were tested and confirmed in healthy participants and patients with homonymous visual field defects. Both groups showed significant biases of fixations and viewing time towards the centre of the screen and the upper screen half. Patients displayed a third bias towards the side of their field defect, which represents oculomotor compensation. Moreover, significant correlations between the extent of these three biases and search performance were found. Our findings suggest a new, more dynamic view of how functional specialisation of the visual field influences behaviour.

Vibrations, Posture, and the Stabilization of Gaze: An Experimental Study on Impedance Control

Vibrations, Posture, and the Stabilization of Gaze: An Experimental Study on Impedance Control R. KREDEL, A. GRIMM & E.-J. HOSSNER University of Bern, Switzerland Introduction Franklin and Wolpert (2011) identify impedance control, i.e., the competence to resist changes in position, velocity or acceleration caused by environmental disturbances, as one of five computational mechanisms which allow for skilled and fluent sen-sorimotor behavior. Accordingly, impedance control is of particular interest in situa-tions in which the motor task exhibits unpredictable components as it is the case in downhill biking or downhill skiing. In an experimental study, the question is asked whether impedance control, beyond its benefits for motor control, also helps to stabi-lize gaze what, in turn, may be essential for maintaining other control mechanisms (e.g., the internal modeling of future states) in an optimal range. Method In a 3x2x4 within-subject ANOVA design, 72 participants conducted three tests on visual acuity and contrast (Landolt / Grating and Vernier) in two different postures (standing vs. squat) on a platform vibrating at four different frequencies (ZEPTOR; 0 Hz, 4 Hz, 8 Hz, 12 Hz; no random noise; constant amplitude) in a counterbalanced or-der with 1-minute breaks in-between. In addition, perceived exertion (Borg) was rated by participants after each condition. Results For Landolt and Grating, significant main effects for posture and frequency are re-vealed, representing lower acuity/contrast thresholds for standing and for higher fre-quencies in general, as well as a significant interaction (p < .05), standing for in-creasing posture differences with increasing frequencies. Overall, performance could be maintained at the 0 Hz/standing level up to a frequency of 8 Hz, if bending of the knees was allowed. The fact that this result is not only due to exertion is proved by the Borg ratings showing significant main effects only, i.e., higher exertion scores for standing and for higher frequencies, but no significant interaction (p > .40). The same pattern, although not significant, is revealed for the Vernier test. Discussion Apparently, postures improving impedance control not only turn out to help to resist disturbances but also assist in stabilizing gaze in spite of these perturbations. Con-sequently, studying the interaction of these control mechanisms in complex unpre-dictable environments seems to be a fruitful field of research for the future. References Franklin, D.
