Organisational health literacy responsiveness: The development of a conceptual framework and organisational self-assessment tool

Using participatory research methods, the scholar developed a conceptual framework describing the characteristics, values, practices and capabilities of health literacy responsiveness organisations. The Framework informed the development of the Org-HLR Self-Assessment Tool and process, which enables organisations to assess their health literacy responsiveness and plan quality improvement activities accordingly.<br /

Plasmid-mediated resistance to arsenite and arsenate in Escherichia coli

Bacterial strains resistant to arsenite, arsenate (or both) are readily isolated from nature. The resistance, in many cases, can be shown to be determined by conjugal plasmids. The mechanisms by which these plasmids confer resistance to arsenic compounds are entirely unknown. This study was undertaken to shed light on some of the physiological and genetic aspects of this resistance using plasmid-bearing strains of Escherichia coli which are highly resistant to both arsenite and arsenate. Most studies were carried out using E. coli J53 (R773) or the plasmid-free strain J53

Field-Testing and Refinement of the Organisational Health Literacy Responsiveness Self-Assessment (Org-HLR) Tool and Process

Health literacy refers to the skills and knowledge that influence a person&rsquo;s ability to access, understand and use information to make health-related decisions, which are influenced by the complexity of their health needs and the demands health services place on them. The aim of this study was to field-test the Organisational Health Literacy Responsiveness (Org-HLR) tool and process to determine their utility in assessing health literacy responsiveness and for supporting organisations to plan health literacy-related improvement activities. Four organisations in Victoria, Australia, field-tested the Org-HLR tool. Data were collected through direct observation, participant feedback, and focus groups. Forty-three individuals participated in field-testing activities, and 20 took part in focus group meetings. Themes relating to the applicability and utility of the Org-HLR self-assessment tool and process were identified. Field-testing resulted in a number of refinements to the tool and process. Twenty-eight indicators were removed, 29 were rephrased to improve their clarity, and four new indicators were added. The revised Org-HLR self-assessment tool contains six dimensions, 22 sub-dimensions and 110 performance indicators. The Org-HLR tool and process were perceived as useful for assessing health literacy responsiveness, prioritising improvement activities, and establishing a benchmark for monitoring and evaluation of improvements over time. Testing generated an improved Org-HLR tool and assessment process that are likely to have utility across a broad range of health and social service sector organisations

Some thoughts on neural network modelling of micro-abrasion-corrosion processes

There is increasing interest in the interactions of microabrasion, involving small particles of less than 10 μm in size, with corrosion. This is because such interactions occur in many environments ranging from the offshore to health care sectors. In particular, micro-abrasion-corrosion can occur in oral processing, where the abrasive components of food interacting with the acidic environment, can lead to degradation of the surface dentine of teeth. Artificial neural networks (ANNs) are computing mechanisms based on the biological brain. They are very effective in various areas such as modelling, classification and pattern recognition. They have been successfully applied in almost all areas of engineering and many practical industrial applications. Hence, in this paper an attempt has been made to model the data obtained in microabrasion-corrosion experiments on polymer/steel couple and a ceramic/lasercarb coating couple using ANN. A multilayer perceptron (MLP) neural network is applied and the results obtained from modelling the tribocorrosion processes will be compared with those obtained from a relatively new class of neural networks namely resource allocation network

Supra-nutritional vitamin E supplementation for 28 days before slaughter maximises muscle vitamin E concentration in finisher pigs

A 4 × 3 factorial experiment (n= 8 pigs per treatment combination) was conducted with 96 female Landrace × Large White pigs to examine the required level of dietary vitamin E and optimum feeding duration before slaughter to maximise muscle vitamin E content in the Longissimus thoracis et lumborum (LTL) muscle. The respective factors were four dietary levels of vitamin E (supplemented as dl-α-tocopheryl acetate; 35, 300, 500, and 700 IU/kg) and three feeding durations (14, 28 and 42 days before slaughter). Vitamin E concentration in the LTL was maximised at 6 mg/kg, which was achieved by feeding a 700 IU vitamin E diet for 28 days before slaughter (P < 0.001). There was no further increase in the vitamin E content of the LTL by feeding the high vitamin E diet more than 28 days before slaughter

Abrasive wear behaviour of conventional and large-particle tungsten carbide-based cermet coatings as a function of abrasive size and type

Abrasive wear behaviour of materials can be assessed using a wide variety of testing methods, and the relative performance of materials will tend to depend upon the testing procedure employed. In this work, two cermet type coatings have been examined, namely (i) a conventional tungsten carbide-cobalt thermally sprayed coating with a carbide size of between ∼0.3 – 5 μm and (ii) a tungsten carbide-nickel alloy weld overlay with large spherical carbides of the order of ∼50 – 140 μm in diameter (DuraStell). The wear behaviour of these two materials has been examined by the use of two abrasion tests, namely the micro-scale abrasion test using both silica and alumina abrasives (typically 2-10 μm in size), and the dry sand-rubber wheel test (ASTM G65), again with both silica and alumina abrasives (typically 180 – 300 μm in size). It was found that when the abrasive particles were of the same scale or larger than the mean free path between the hard phase particles, then the matrix phase was well protected by the hard phases. Testing (in both test types) with alumina abrasives resulted in wear of both the hard carbide phases and the matrix phases in both the thermally sprayed coating and the weld overlay, with the thermally sprayed coating exhibiting lower wear rates. The wear behaviour of the materials with the more industrially relevant silica abrasive was more complex; the thermally sprayed coating exhibited a lower wear rate than the weld overlay with the fine abrasive in the micro-scale abrasion test due to effective shielding of the matrix from abrasive action due to the fine reinforcement particle size. In contrast, with the coarser silica abrasive in the dry sand-rubber wheel test, the weld overlay with the large carbides was able to provide matrix protection with low rates of wear, whereas the thermally sprayed coating wore by fracture of the more brittle microstructure. These findings demonstrate the importance of selection of appropriate laboratory test procedures and abrasives to simulate behaviour of materials in service environments

The effect of conventional and deep litter housing on belly composition of finished Large White x Landrace gilts

In this study we hypothesised that the tissue distribution in growing pigs would differ between pigs housed on deep litter and pigs housed conventionally. We also expected the impact of housing type on fat deposition and distribution would be more pronounced during the finishing period because the proportion of fat deposited in the total gain increases with age

Effect of conventional and deep litter housing on pig growth performance and carcass characteristics

Anecdotal observations suggest that pigs raised in deep litter systems are fatter than pigs raised in conventional systems. To manage fat deposition in pigs, some producers wean pigs into deep litter and then at about 13 weeks of age move the animals into conventional facilities for finishing. Differences in growth and carcass quality have been reported between pigs raised outdoors and conventionally (Gentry et al., 2002). We would expect the physical and thermal differences between conventional and deep litter housing systems to affect the partitioning of energy for lean and fat deposition during growth. In this study we hypothesised that growth performance and carcass composition would differ for pigs housed conventionally or on deep litter

Estimating individual cone fundamentals from their color-matching functions

Estimation of individual spectral cone fundamentals from color-matching functions is a classical and longstanding problem in color science. In this paper we propose a novel method to carry out this estimation based on a linear optimization technique, employing an assumption of a priori knowledge of the retinal absorptance functions. The result is an estimation of the combined lenticular and macular filtration for an individual, along with the nine coefficients in the linear combination that relates their color-matching functions to their estimated spectral-cone fundamentals. We test the method on the individual Stiles and Burch color-matching functions and derive cone-fundamental estimations for different viewing fields and matching experiment repetition. We obtain cone-fundamental estimations that are remarkably similar to those available in the literature. This suggests that the method yields results that are close to the true fundamentals
