Comparative effectiveness report : online survey tools

Purpose. A group of Australian researchers seeking an accessible online survey tool discovered to their concern that most commercially available survey tools are not actually ‘useable’ by a significant number of assistive technology users.
Method. Comparative effectiveness analysis of 11 popular survey tools. A bespoke survey tool was subsequently created to meet all accessibility guidelines and useability criteria as determined by the wide range of assistive technology users with whom the research team was working.
Results. Many survey tools claim accessibility status but this does not reflect the actual situation. Only one survey met all compliance points; however, it was limited by inflexible layout and few options for question types; some surveys proved unusable by screen reader. All surveys reviewed represented a compromise between accessibility and breadth of functionality.
Conclusion. It would appear the voices of a proportion of people living with disability are absent from the data collected by surveys, and that current accessibility guidelines, even where implemented, still fall short of assuring useable survey tools. This article describes one online solution created to successfully survey a broad population, and outlines a design approach to encompass user diversity.

The clinical application of three screening tools for recognizing post-partum depression

Postnatal depression is a major health issue for childbearing women world-wide, as it is not always identified early. This study aimed to evaluate the clinical application of three screening instruments for the early recognition of post-partum depression, the Postpartum Depression Prediction Inventory, the Postpartum Depression Screening Scale and the Edinburgh Postnatal Depression Scale, and to examine nurse interventions following use of the instruments. Data were collected at two points, at 28 weeks prenatal (107 women) and eight weeks postnatal (84 women). Results showed that 17% of the women scored significant symptoms of post-partum depression and 10–15% had a positive screen for major postnatal depression. There was a statistically significant correlation between the total score on the Postpartum Depression Screening Scale and the Edinburgh Postnatal Depression Scale. Of those eight women identified as being at risk, seven had received anticipatory guidance and five had received counselling by the nurses. The Postpartum Depression Prediction Inventory enabled nurses to identify women at risk of post-partum depression and offer interventions.

Medication compliance and satisfaction with treatment for HIV disease in a sample of African-American crack cocaine smokers

The development of treatment regimes for African-American HIV-infected crack cocaine users has often been based on assumptions about compliance with medication regimes rather than evidence. This study sought to obtain baseline information on the adherence to antiretroviral medications by members of this important risk population in Houston, Texas. It was found that for only 5 of a range of 16 antiviral medications was there a significant correlation between levels of compliance reported by respondents and their beliefs as to how effective these medications are. Medication compliance was also found not to be associated with frequency of crack cocaine use in the month prior to interview. Furthermore, irrespective of both gender and their reported extent of medication compliance, the respondents tended to report positive relationships with their treating physician, with higher levels of satisfaction reported by women. These results suggest that the majority of African-American crack cocaine users are able to comply with HIV treatment regimes, with more than half (53%) claiming full compliance for one or more medications, and a further one third (31%) claiming compliance more than half the time. Moreover, these findings suggest that they will continue to take antiretroviral medications even if they have doubts about the effectiveness of these medications.

Conservative treatment of patellar tendinopathy

Patellar tendinopathy disrupts athletic careers in several sports and is resistant to many forms of conservative treatment. Outcome after conservative treatment has been minimally investigated, and the effect of these treatments on the pathology of overuse tendinopathy are not well understood.

The clinical assessment of patellar tendinopathy appears straightforward, but evidence suggests that the importance of imaging and palpation in diagnosis and ongoing assessment may be overestimated. There is a lack of clinically relevant research on which to base treatment. However, the principles of management for patellar tendinopathy derived from clinical experience include load modification, musculotendinous rehabilitation, and intervention to improve the shock absorbing capacity of the limb. The role of electrophysical agents, massage, and stretching in the treatment of patellar tendinopathy are also discussed. The progression of treatment is based on clinical grounds due to a lack of reliable subjective and objective tools to assess recovery.

The failure of some conservative programs could be due to either athlete compliance or practitioner expertise. The management of patellar tendinopathy is complex, and if the physiotherapist addresses all the principles of treatment, the chance of success could be increased.

A comparison of search functions and other navigational tools provided on government websites

This paper reports the outcomes of a study that evaluated the effectiveness of search functions compared to other navigational tools available on government websites. The study used an observation exercise triangulated with a post observation interview. Results suggest that while there wasn't any significant difference in effectiveness between search functions and other navigational tools, the skill with which the search function is implemented and participants' familiarity with the website, are fundamental determinants of users' opinions. Implications of the findings for research and practice are discussed.

Stress analysis of compression of aluminium with rotating tools

Compression tests carried out on aluminium specimens showed that when the die was rotated the compression load dropped. A slab method is employed to examine this process. The load reduction is explained by the deviation of friction vector due to the relative circumferential movement between the die and the material. This mechanism is incorporated into a theoretical model and an expression is derived for compression pressure. Analytical solutions established compare favourably with experimental results. It is also shown that there is a limitation to the load reduction: the compressive load can never be lower than 70 percent of the yield limit.

Training packages and the AQTF: freedom to move or components of a compliance-driven straightjacket?

This paper reports on a PhD research project being undertaken through the Faculty of Education, Deakin University. Training Packages and the Australian Quality Training Framework (AQTF) form part of the ruling relations of VET, but how do they operate in practice? Do they provide frameworks within which training professionals are free to use judgement and respond in innovative ways to local learning and assessment contexts? Do they impose rigid 'guidelines' within which the decision-making authority of practitioners over appropriate practices is displaced by that of auditors, constraining creativity and creating pressures towards conformity? Or does their impact vary, depending on how they are interpreted and who is doing the interpreting? My PhD research explores issues relating to the use of Training Packages in workbased learning. Interview data suggests that, in practice, different training organisations respond very differently to a regulatory framework that aims to achieve national consistency. Some practitioners describe working in a compliance-driven environment, in which their ability to meet the needs of learners is stifled by standardised training and assessment practices imposed by Training Packages and the AQTF. This view is reflected in phrases such as 'you're not allowed to…', and 'you always feel uneasy because you've got AQTF compliance, inspections, auditors'. In contrast, other practitioners talk about having freedom to design learning and assessment programs for their particular target group and context, providing they stay within broad guidelines that guarantee national recognition of qualifications they issue. This view is reflected in comments such as 'it just leaves it open … to be as creative and flexible as you like', and 'It just gives us freedom'. This paper explores the proposition that the impact of these abstract and generalised texts is influenced by local interpretations, and it considers the role that organisational culture plays in determining these interpretations.

Ecologically sustainable development and architecture: the impact of rating tools

The concept of Ecologically Sustainable Development (ESD) has become an important issue – albeit often scarcely applied – in the design of commercial buildings. To encourage the adoption of sustainable strategies in the practice of design and to address the environmental problems caused by these developments, governments and organisations of various countries have proposed the adoption of scorecard rating tools to inform designers of the impact of their decisions and to present a way of establishing project goals and objectives early in the design process. In Australia, the recent introduction of the Green Star Rating Tool (Office Design) is believed to provide the architects with a ‘whole-of-building’ assessment of the environmental impact of their design by creating a checklist against which to benchmark performance. This paper follows the design of a commercial building, evaluating the impact of Green Star in the overall process. The results of the study suggest the need to include the use of scorecard rating tools in a more integrated model, where ESD is considered at every stage of design and construction rather than being a separate component applied only to promote the ‘greenness’ of a building. Rating tools can be an asset to the design team, provided sustainable requirements are reinforced throughout the entire process.

Occupational safety and health management systems in Australia: barriers to success

The growing popularity of occupational safety and health management systems in Australia has stimulated critical debate about their effectiveness. This paper asks whether the performance of such systems lives up to expectations. Making use of a research review and an extensive interviewing programme, the paper draws several conclusions. First, it observes that the definitional requirements for an occupational safety and health management system have been watered down, making it more likely that organisations can claim to have a system, but less likely that it will be effective. Second, a review of empirical research reinforces the view that systems can improve health and safety outcomes, but only if they meet strict conditions concerning senior management commitment, effective workforce involvement and programme integration. Third, several barriers to successful implementation are identified, including the failure to meet essential success factors, the inappropriate application of audit tools to ensure compliance, and their problematic application in certain sectors such as small business, contractors, and the part-time and temporary workforce. The paper concludes that occupational safety and health management systems can live up to their promise, but often fail to do so because of inadequate implementation or application in hostile environments.

Anthropometric and biochemical markers for nutritional risk among residents within an Australian residential care facility

The risk of malnutrition is high among elderly population, yet few studies have measured indicators of nutritional status among Australian aged-care residents. To determine the relationship between nutritional status and bone density, hand grip strength, and the timed-up and go test, in a group of Australian aged-care residents. Anthropometric and biochemical analysis measured in subjects recruited to be part of a six month multivitamin supplementation study. One hundred and fifteen subjects participated (68% female). The mean (SD) age and body weight was 80.2(10.6) years, and 66.5(15.0) kg, respectively. Eleven percent were underweight (body mass index, BMI, <or =20.0 kg/m(2)), and 20% were obese BMI >or =30 kg/m(2)). Low serum 25-hydroxy-vitamin D (25(OH)D, <or =50 nmol/L) concentrations were found among 79% of subjects. After adjustment for body weight, there was an association between serum 25(OH)D and bone density (heel ultrasound) (r=.204, p=.027). Low serum zinc <or =10.7 micromol/L) concentrations were found among 46% of subjects; this group had a slower timed up and go time compared with those with higher zinc concentrations (n=19, 44.6 +/- 5.6 seconds vs. n=27, 30.0 +/- 3.3 seconds, p=.020). There were no associations between nutritional markers and hand grip strength. In this group, more than (3/4) of subjects had low serum 25(OH)D, and 46% had low zinc concentrations. Serum 25(OH)D was associated a lower bone density and zinc with a slower walking time. This indicates that the elderly in long term residential care facilities are at high risk for poor nutritional status, potentially increasing morbidity and mortality.

A lower bound on effective performance testing for digital forensic tools

The increasing complexity and number of digital forensic tasks required in criminal investigations demand the development of an effective and efficient testing methodology, enabling tools of similar functionalities to be compared based on their performance. Assuming that the tool tester is familiar with the underlying testing platform and has the ability to use the tools correctly, we provide a numerical solution for the lower bound on the number of testing cases needed to determine comparative capabilities of any set of digital forensic tools. We also present a case study on the performance testing of password cracking tools, which allows us to confirm that the lower bound on the number of testing runs needed is closely related to the row size of certain orthogonal arrays. We show how to reduce the number of test runs by using knowledge of the underlying system

An effective and efficient testing methodology for correctness testing for file recovery tools

We hereby develop an effective and efficient testing methodology for correctness testing for file recovery tools across different file systems. We assume that the tool tester is familiar with the formats of common file types and has the ability to use the tools correctly. Our methodology first derives a testing plan to minimize the number of runs required to identify the differences in tools with respect to correctness. We also present a case study on correctness testing for file carving tools, which allows us to confirm that the number of necessary testing runs is bounded and our results are statistically sound.

Standardizing anthropometric measures in children and adolescents with new functions for egen

A new function for egen has been developed to allow transformation of child anthropometric data to z-scores using the LMS method and the reference data available from the 1990 British Growth Reference and the 2000 US CDC Growth Reference. An additional function allows for children to be categorized according to body mass index (weight/height ²) using international cutoff points recommended by the Childhood Obesity Working Group of the International Obesity Taskforce.
