RemmbrMe

Dirk De Bruyn’s eleven-minute RemmbrME (2007) is a visually engaging film that documents in a painterly fashion the numerous gaps and intersections between analogue and digital moving image manipulation. RemmbrME is a work that critically focuses on the re-shaping of the lost material that is germane to a basic cameraless direct-on-film practice and resonates important ideas concerning the increasing fusion between analogue and digital image-making in our everyday culture.

What is wrong with a big house?

ln Australia in the 1950s, the average house size was approximately 100 mz. By 2008, the average size of a new house had risen to approximately 238 mz i.e. an increase of nearly 140%. Over the same period, occupancy levels have fallen by nearly one third from 3.7 to 2.5 persons per household. The aim of this paper is to contrast the total and per capita resource demand (direct and embodied energy, water and materials) for two houses typical of their respective era and draw some conclusions from the results. Using the software Autodesk Revit Architecture and drawings for typical 1950 and 2009 houses, the material quantities for these dwellings have been determined. Using known coefficients, the embodied energy and water in the materials have been calculated. Operating energy requirements have been calculated using NatHERS estimates. Water requirements have been calculated using historical and current water data. The greenhouse gas emissions associated with the resource use have also been calculated using established coefficients. Results are compared on a per capita basis. The research found that although the energy to operate the modern house and annual water use had fallen, the embodied energy and associated greenhouse gas emissions from material use had risen significantly. This was driven by the size of the house and the change in construction practices.

New village models : examining the sustainability of existing realities and hypothetical visions

Zavoj is a mountain village in the Republic of Macedonia. While the village has become a site of emigration due to the mass exodus of its inhabitants, new house constructions have appeared. Scattered through deteriorating vernacular dwellings are new houses, and new fragments of houses attached to old houses. These new houses and house-fragments are introduced by emigrants returning to the village temporarily, and not by the remaining local village inhabitants. In the new millennium their number has dramatically increased. Migration has produced an incongruous mixture of architectures giving rise to questions about sustainable development in relation to new constructions in traditional environments? New buildings in the village are symptomatic of a much more universal phenomenon that is transforming vast rural landscapes into loosely urbanized regions. In contrast to this existing reality, a program in the Faculty of Architecture, Ss. Kiril & Metodij University, Skopje, Republic of Macedonia, is exploring alternative visions for the revitalization of the village. Can these offer more sustainable design approaches to the village? This paper examines sustainability in the dialectic between new constructions in existing villages and hypothetical visions for the new village.

Impact of stresses imposed on macroinvertebrate communities in two suburban streams

The aim of the project was to determine factors which explain the distribution of macroinvertebrates in two Melbourne streams both drastically affected by urbanisation. A detailed description is given of Dandenong Creek, flowing through the south-eastern suburbs, and Darebin Creek, in the northern suburbs, emphasising stream features likely, or known, to influence the drift and benthic fauna. Faunal sampling was carried out in Dandenong Creek from June 1992 until July 1993, and in Darebin Creek from February 1995 until March 1998. Physicochemical parameters were also recorded. The collected data, together with previously existing data, were analysed using multivariate analyses: non-metric multi-dimensional scaling (NMDS); analysis of similarities (ANOSIM); matching biotic and abiotic variables using BIOENV, and principal component analysis (PCA). Various biotic and diversity indices were calculated in an attempt to identify the major factors responsible for the failure of the fauna to recover from previously more seriously degraded water quality. The contribution of drift to the colonisation potential in Dandenong Creek appeared to be impacted by retarding basins, underground barrel-draining and channelization. Results also indicated that increased conductivity adversely affected the fauna in the lower reaches of Dandenong Creek. It was concluded that in Darebin Creek, high nutrient levels, as well as other pollutants, had resulted in low macroinvertebrate diversity in both the drift and benthos. If, as this study suggests, faunal diversity is a valid measure of stream health, the following factors need to be addressed for catchment-wide, stream management: lack of riparian zone vegetation (increasing bank erosion and making the benthic habitat unstable, with greater temperature variability); control of stormwater runoff (flow variability, increased conductivity, nutrient levels, sediment loads, sewage effluent, industrial discharges and heavy metals), and to modify retarding basins to increase stream continuity.

Comparison of defects in houses constructed by owners and registered builders in Victoria 1988-1996

The lack of attention to quality control by house builders in the Australian State of Victoria has been a contentious issue for more than two decades. Ina an attempt to improve the quality of housing, various mechanisms such as voluntary and compulsory registration schemes have been adopted and discarded by industry-based organisations and government. While builders are encouraged to improve construction quality, little is known and published about the quality of housing produced by owner builders specifically during the seven year warranty period after construction is completed. With this in mind, this thesis presents research findings that compare the latent defects in houses built by owner builders with those of registered builders. Using inspection reports provided by Archicentre a sample of 1772 houses, of which 1002 were owner builders and 770 were registered builders

Development of benchmarks for determining infrastructure needs for the aged

This project developed benchmarks and benchmarking procedures to indicate the current and future infrastructure requirements of the aged in regional centres. The benchmarks correlate the infrastructure requirements of the aged with demographic trends. The research also modelled aged infrastructure requirements within the broader context of the sustainability of cities.

Planning for ember attack within the interface

This dissertation explores the relationship between the urban rural interface, with particular reference to air pressure, wind patterns, and the build up of hot ash deposits adjacent to combustible surfaces, in order to devise strategies relating to the design of building forms.

1970s Australian ecologically designed house

This study found that the influence of global environmentalism and local experimentations in alternative forms of building and lifestyle drove the creation of the 1970s Australian ecological house. Its conception was the emphatic manifestation of various social, ideological and political influences in Australia during this period.

Empirical applications of economic principles in producer price index analysis

The research analyses economic linkages of producer price indices of the construction industry in Australia and relationships between construction and house prices. A range of econometric techniques are applied to analyse construction and house prices. The economic equilibrium and dynamic relationships among regional markets are investigated based on producer price index analysis.

A grounded theory of intuition among occupational therapists in mental health practice

Objectives: This study aimed to explore occupational therapists’ understanding and use of intuition in mental health practice.
Method: Using a grounded theory approach, a theoretical sample of nine occupational therapists practising in mental health settings participated in semi-structured interviews. Data were analysed using the constant comparative method.
Findings: Intuition was found to be embedded within clinical reasoning. From the data, intuition was defined as knowledge without conscious awareness of reasoning. The participants viewed intuition as elusive and underground, and suggested that professional experience led to a more comfortable use of intuition. Using intuition relied on therapists’ understanding of their own and others’ emotions, and intuition partnered analysis within their clinical reasoning. A grounded theory of the use of intuition in mental health settings is proposed.
Conclusion: Occupational therapists practising in mental health settings understand intuition to be an instinctive understanding of situations, resulting from their professional experience and the understanding of emotions.

Study on the visual performance of a vernacular dwelling in Egypt

Vernacular dwelling buildings located in hot arid regions are well known for their sensitive architecture response to the region’s climatic conditions and the socio-cultural norms. The architectural value of these buildings is not only limited to their historical merit, but also to the human conscious adaptation to its context and the optimum utilisation of natural resources creating both a pleasant and a functional environment. The majority of these traditional dwellings are well recognised for their unique perforated fenestration system and courtyard arrangement that evolved to control the harsh solar, climatic conditions without compromising the quality of space and occupants’ wellbeing. However, the successful design of these features and solutions cannot be fully appreciated without understanding the nature of daylight and solar radiation in which these buildings are revealed. This paper investigates the impact of the characteristic of the dense narrow streets of medieval cities on the visual performance of a typical courtyard house in Cairo.The paper examines the daylight  behaviour of one of the well-known historic alleys and of a courtyard house in Cairo. The paper analyzes and measures the variability in the visual perception and comfort for a typical pedestrian street and the occupants of the house using a simulation modelling tool (Integrated Environmental Solutions (IES) software). The paper gives an insight into the overall visual performance of the urban fabric that shapes of the microclimate, which is an important ingredient of the overall identity of the place.

Spatial and temporal variation of house prices

This thesis originally developed a spatial and temporal analysis approach. This approach was applied to investigate the variation of house prices in Australia. The findings discovered the behaviours of house prices and the interconnections between them across the Australian cities.
