A house in history, heritage and tourism : shifting times at Blundell's Cottage, Canberra

The history of history's institutions can offer a gritty context in which to understand historical production. A wide spectrum of influences, from the personal to the intellectual to the political, can be seen at work in shaping the history made and communicated at Blundell's Cottage over the years. Even though it has always been a humble participant in the project of history, its products probably reach some of history's larger audiences. Hence it is worthwhile to review fifty years of historio-museography.

From parallel descriptions to parallel grammars: unravelling the complexity of Lutyen's country house folio

Based on an analysis of a corpus of forty of Sir Edwin Lutyens's country house designs (Rollo 1997) a procedure for developing Parallel Descriptions will be discussed. This procedure will attempt to facilitate an integrated approach to the analysis of complex architectural forms and will provide a framework for investigating the development of parallel grammars. This is an approach which acknowledges that design does not necessarily involve the importance of one aspect, but rather a number of coextensive issues with emphasis on the ordering and priority of these issues periodically shifting.

'Green' treatment of acid mine drainage - a step towards sustainability

Sustainability is becoming increasingly important in the mining and mineral processing industries and must incorporate the associated waste products. Acid mine drainage (AMD) is one such by-product and is one of the most serious environmental problems facing the minerals industry today. The oxidation of sulphidic mine wastes often continues for a substantial period of time after mine closure, resulting in difficult and costly remediation and rehabilitation works. Mining companies are often reluctant to spend increasing amounts of money on waste treatment when the mine life is limited or even finished. Hence a simple, low maintenance and low-cost method of treating AMD is required. Whilst this paper does not address the issue of AMD, it does propose methods for removal of individual species from AMD with potential benefits, including raising AMD pH.

A novel concept of using biosolids as a biological adsorbent, or ‘biosorbent’, of metals from AMD is being investigated at a laboratory/pilot scale level. Biosolids are a by-product resulting from the biological treatment of wastewater, and have been previously shown to adsorb metals from aqueous solutions. This could lead to an environmentally sustainable or ‘green’ method for treating both AMD discharges and disposing/reusing the biosolids.

The result of a laboratory-scale study of the biosorption of Zn(II) is presented in this paper. Physical parameters including reaction kinetics, mixing speed and solution pH were investigated. Solution pH also rose an average of 2 pH units over the 24 hour equilibrium time – a valuable side effect when treating acid mine drainage. The outcome of the study highlights the usefulness of biosolids as a biosorbent for the removal/recovery of metal ions from acid mine drainage. A simple, low-cost treatment technology requiring low maintenance would be beneficial to the mining industry to address some issues relating to AMD and would help integrate environmental and economic considerations into sustainable environmental management.

Dwelling in the landscape: from Blairgowrie House to Portsea Palace

Ackerman begins his book "The Villa" (1995) with these words: 'A villa is a building in the country designed for its owner's enjoyment and relaxation .... [it] accommodates a fantasy which is impervious to reality.' He concludes: , ... the country, in exacting confrontations with the immanent brute forces and sensuous enchantments of nature, prompts inspired responses.' Blairgowrie House - the villa in the landscape - was built in the 1870s and the 'Portsea Palace' - a personal club med resort - in the late 1990s. The notion of an inspired response and the concept of dwelling poetically are manifestly absent in the Portsea Palace. Why?

This paper explores architecture and landscape - particularly 'domestic' architecture and coastal landscapes in Victoria's Nepean Peninsula. It looks closely at what architects mean when they say their design reflects place, relates to site, is climate specific, is close to nature, responds to the landscape, and/or is sensitive to the environment. Exemplars from different centuries are examined in their philosophical contexts and frames of reference. The complexities of the notion of place and identity, belonging, and dwelling (in the Heideggerian sense) are examined to identify the shift that has occurred over time as science and technology have ostensibly freed 'modern man' from 'a direct dependence on places' (Norberg Schultz). The alienation and loss that has eventuated - for humans and for the environment - will be critically analysed and assessed.

Granger causality among house price and macroeconomic variables in Victoria

This study analyses the dynamic causality of four macroeconomic variables on house prices. The four macroeconomic variables have interrelationships with house prices in certain lagged terms, but these relationships are not always the same as the notions put forward in prior research. The relationships are detected to be unstable in the three observation periods. The instability of these relationships would cause difficulty in predicting house prices in the market, especially for policy makers and market participants.

The normative distribution of chest tube drainage volume after coronary artery bypass grafting

Background
Little evidence exists to describe expected volumes of chest tube (CT) drainage after coronary artery bypass grafting (CABG).

Objectives
The study objective was to map the trajectory of CT drainage volumes from insertion to removal after CABG.

Design

This was a retrospective, descriptive study.
Patients
The study included 239 patients who underwent CABG at a single metropolitan hospital in Melbourne, Australia.

Results
The sample (N = 234), aged 68.7 years (standard deviation [SD] 9.9), was predominantly male (N = 185, 79.1%). The mean duration of CT insertion was 45.2 hours (SD 26.7), and total drainage volume was 1300.6 mL (SD 763.8). Drainage volumes plateau to 31 mL per hour, 8 hours after surgery. From 24 to 48 hours, the mean drainage was 21 mL per hour. Drainage volumes varied between genders.

Conclusions
Evidence of similar drainage patterns in other populations is difficult to locate. If the pattern of drainage shown in this study is consistent, experimental intervention studies comparing standard removal time and earlier removal are recommended. If not, prospective collection of relevant preoperative, intraoperative, and postoperative factors across multiple sites is necessary to determine which patient or practice variations influence CT drainage patterns after CABG.

Sudden drawdown and drainage of a horizontal aquifer

Drainage of a saturated horizontal aquifer following a sudden drawdown is reanalyzed using the Boussinesq equation. The effect of the finite length of the aquifer is considered in detail. An analytical approximation based on a superposition principle yields a very good estimate of the outflow when compared to accurate numerical solutions. An illustration of the new analytical approach to analyze basin-scale field data is used to demonstrate possible field applications of the new solution.

Full house theory: A new theory for assessing demand for arts centers

In this article I will establish an underpinning theory to apply in measuring demand for a new arts center (theater, museum, gallery, multipurpose space, tourism destination, or cultural precinct). The new theory is called "Full House Theory"-so called because it aims to provide an equation among the factors that result in maximum occupancy and use of an arts center or cultural facility. Existing theories used in the retail sector offer a distance-and-time analysis of expected customer demand but do not include differentiated product-demand analysis. Cultural planning literature examines community need in relation to cultural development but fails to provide a formula to predict sustainable demand. In addition, I will analyze the theories and methodologies in current use as well as their weaknesses in assessing cultural facility demand.
