The Australian DRG variant (Australian National DRGs from versions 1 to 3, and Australian Refined DRGs thereafter) compares favourably with other variants in use around the world. This view is supported by a variety of empirical studies (see for example Reid, Palmer & Aisbett 2000) and by experiences of its adoption by several health care systems. An example is its recent selection for use in G...

In 1902 Burnside [4] wrote "A still undecided point in the theory of discontinuous groups is whether the order of a group may be not finite while the order of every operation it contains is finite". This leads to the following problem, now called the Burnside problem: "If a group is finitely generated and of finite exponent, is it finite?" This is a very difficult question so a weaker form know...

Occupational diseases are a significant problem affecting public health. Safety training is an important method of preventing occupational illness. Training is increasingly being delivered by computer although theories of learning from computer-based multimedia have been tested almost entirely on college students. This study was designed to determine whether these theories might also be applied...

In a pair of recent articles, the author develops a general version of small cancellation theory applicable in higher dimensions ([5]), and then applies this theory to the Burnside groups of sufficiently large exponent ([6]). More specifically, these articles prove that the free Burnside groups of exponent n ≥ 1260 are infinite groups which have a decidable word problem. The structure of the fi...

Qualitative data collected in Thailand through a series of 26 focus groups held separately with elderly individuals and adults with elderly parents provides insights into Thai views on a variety of issues related to the living arrangements of the elderly. These include the benefits and problems associated with coresidence, the choice of the coresident caregiver, mechanisms encouraging co-reside...

1. No difference in health was observed between men on megadosage of ascorbic acid and controls during the year of an Antarctic expedition. 2. All men appeared to have a satisfactory intake of ascorbic acid throughout the year. 3. There was a statistically significant decrease in excretion of ascorbic acid by men on megadosage over the year, and by the controls. 4. The decline in excretion by t...

L asymmetry in beta activity in the dyslexic group, again in both tasks. Theta activity did discriminate between the two tasks in the dyslexic group. In the phonological task, task-related frontal theta in the dyslexic group was significantly different from the control group, with the former showing an increase in amplitude and the latter a decrease. In the visual task, there was no significant...

To test for retrospective effects of sucrose ingestion in the anticipatory contrast procedure, 4 experiments examined intake of an initial 0.15% saccharin solution as a function of the unsignaled interspersing of days in which the 2nd solution was 32% sucrose or 0.15% saccharin. In Experiment 1, rats that received alternating saccharin-saccharin days and saccharin-sucrose days drank less saccha...
