Master of Visual Arts / Studio work The Postgraduate Degree Show is held from 6PthP December 2005 to 17PthP December 2005 and my work is installed in the Sculpture Studio (as a gallery space) at Building 29 of Sydney College of the Arts, Sydney. There are three installations of work, each with a series of paintings and object-models. The media I am using are oil on canvas for the paintings and wood for the models. The titles of my exhibition pieces are Project Studio (Stairs), Project Rented Room (Chair), Project Rented Room (Bed), and Project Object. Together they are entitled Project: Spanning the Space of Dislocation. The project explores the perception of space and its representation through painting and installation. The starting point is the image of familiar architectural objects to which I displace the experience of it from one site (my painting studio) to another (the gallery space) through painting as index. I use the technique of ambiguous linear forms in painting and the reflexive reading of orthogonal projective planes in installation to further extend the viewer’s perception of space and objects. The aim is to show that space has a meaningful relationship to objects and bring about a renewed awareness of habitual practice in seeing and representing space. UResearch paperU I have divided my research paper in two chapters. Chapter one explores the issue of spatial representation through ambiguity of simple linear forms and painting as index. My concern is on space being less important to objects in the distinction between space as ground and object as figure. Within this chapter I argue for an extended and a reflexive mode of seeing and representing space and objects instead of for a ground-figure contrast. By mapping my experience on a usual working site and displacing it to another space, I show that my perception of space is extended such that the boundary between the familiar and foreign (that is, space-object distinction) is blurred. Chapter two explores the method of presentation through painting and installation in a gallery and addresses the viewer’s space of perception with the work. I also discuss possible reflexive readings on the projective planes of the work which further extend the perception of it.

Embodied accounts contend that word meaning is grounded in sensory-motor representation. In support of this view, research has found rapid motor priming effects for words like eagle or shoe, which differ as to whether they are typically associated with an up or down spatial direction. These priming effects are held to be the result of motor representations evoked as an obligatory part of understanding the meaning of a word. In a series of experiments, we show that prime words associated with up or down spatial locations produce vertical perturbations in the horizontal movements of a computer mouse, but that these effects are contingent either on directing conscious attention to the spatial meaning of the word, or on the inclusion of the primed spatial direction in the response set, and that this is true even for strongly spatial words such as up and down. These results show that the motor representations associated with such words are not automatically evoked during reading. We discuss implications for claims that spatial representations reflect our embodied perception of the world. / Graduate

Current explanations for anchoring phenomena seem to be unable to account for the diversity of effects found by 40 years of research. Additionally, the theories do not have much to say about the processes that make anchors so resilient to modification. I argue that by focusing on the mechanisms involved in spatial representation, we can account for most anchoring effects which have spatial components.

The role of the spatial representation in the relation between chronic exposure to NO2 and respiratory health outcomes is studied through a spatial approach encompassing three conceptual components: the geography of susceptibility, the geography of exposure and the geography of risk. A spatially explicit methodology that defined natural neighbourhoods for the city of Ottawa is presented; it became the geography of analysis in this research. A LUR model for Ottawa is developed to study the geography of exposure. Model sensitivity to the spatial representation of population showed that dasymetric population mapping did not provide significant improvements to the LUR model over population at the dissemination block level. However, both the former were significantly better than population represented at the dissemination area. Spatial representation in the geography of exposure was also evaluated by comparing four kriging and cokriging interpolation models to the LUR. Geostatistically derived NO2 concentration maps were weakly correlated with LUR model results. The relationship between mean NO2 concentrations and respiratory health outcomes was assessed within the natural neighbourhoods. We find a statistically significant association between NO2 concentrations and respiratory health outcomes as measured by global bivariate Moran’s I. However, for regression model building, NO2 had to be forced into the model, demonstrating that NO2 is not one of the main contributing variables to respiratory health outcomes in Ottawa. The results point toward the importance of the socioeconomic status on the health condition of individuals. Finally, the role of spatial representation was assessed using three different spatial structures, which also permitted to better understand the role of the modifiable areal unit problem (MAUP) in the study of the relationship between exposure to NO2 and health. The results confirm that NO2 concentration is not a major contributing factor to the respiratory health in Ottawa but clearly demonstrate the implications that the use of opportunistic administrative boundaries can have on results of exposure studies. The effects of the MAUP, the scale effect and the zoning effect, were observed indicating that a spatial structure that embodies the scale of major social processes behind the health condition of individuals should be used when possible.

This thesis examines the role of function in representations of space by robots - that is, dealing directly and explicitly with those aspects of space and objects in space that serve some purpose for the robot. It is suggested that taking function into account helps increase the generality and robustness of solutions in an unpredictable and complex world, and the suggestion is affirmed by several instantiations of functionally conceived spatial models. These include perceptual models for the "on" and "in" relations based on support and containment; context-sensitive segmentation of 2-D maps into regions distinguished by functional criteria; and, learned predictive models of the causal relationships between objects in physics simulation. Practical application of these models is also demonstrated in the context of object search on a mobile robotic platform. / QC 20111125

Les grammaires du portugais présentent un système ternaire de démonstratifs, mais l’usage effectif de la langue, dans les deux variétés du portugais, montre qu’il y a une tendance à l’établissement d’un système binaire avec une neutralisation entre les formes des 1ères et 2èmes personnes en opposition aux formes de la 3ème personne. Dans cette étude nous analysons l’usage des démonstratifs dans un corpus de romans graphiques en portugais brésilien et en portugais européen. Notre objectif principal est de vérifier si les deux variétés ont les mêmes conceptions d’usage de ces formes linguistiques concernant la dimension spatiale et personnelle. En s’appuyant dans une perspective psychosystématique (Guillaumienne) de la représentation de l’espace et des différences formelles de la représentation de l’image, notre hypothèse est qu’il y a un possible changement dans l’orientation des opérations mentales mises en jeu par le fonctionnement du système de langue d’un locuteur brésilien ou portugais. Les deux variétés du portugais oral présentent des neutralisations qui ne délimitent pas trois champs référentiels clairement séparés et pourront entraîner une restructuration du système des démonstratifs. Alors que le portugais brésilien généralise la forme de 2ème personne esse, le portugais européen généralise la forme de 1ère personne este. En outre, nous avons montré que le renfort par le biais des adverbes de lieux afférents, crée des oppositions discursives qui dépassent la reconstruction d'une division ternaire de l'espace géographique. / Portuguese grammars set as a ternary system of demonstratives, but in the effective use of language we observe a tendency to install a binary system in both European and Brazilian Portuguese. The forms of 1st and 2nd person are neutralized in opposition to the forms of 3rd person, in the paradigm of determinants as well as in the paradigm of pronouns. In this study, we analyze the use of demonstratives and adverbs of place in a corpus of graphic novels of Brazilian Portuguese and European Portuguese. Our main objective is to verify if there are different forms of coding the dimensions of space and person in these two varieties. This work is aligned with Guillaume's psychosystématique concerning the representation of space and the formal differences in the manner how speakers represent themselves as persons. Our main hypothesis is that possible differences in the use of demonstrative forms reflect different orientation of mental operations adopted by Portuguese and Brazilian speakers. The two varieties represented oral Portuguese have neutralizations compromising the distinction among three referential domains: the 1st person, the 2nd person and the 3rd person. However, this trend appears differently in each variety especially in relation to the determinant demonstratives. While Brazilian Portuguese generalizes the form of second person esse, European Portuguese generalizes the 1st person form este. Furthermore, we show that the referential strengthening through reinforced sequences with adverbials of place, more frequent in Brazilian Portuguese, creates discursive oppositions that go beyond the reconstruction of a ternary division of geographical space.
