Building Research Supervision and Training across Australian Universities

`Building Research Supervision and Training in Australian Universities was undertaken with the aims of identifying existing higher degree research supervisor training provisions; identifying current and future needs of supervisors and making recommendations that assist universities in their ongoing development of effective higher degree research supervisor training

Measuring quality of life in ALS/MND: validation of the WHOQOL-BREF

Objectives: The World Health Organization Quality of Life-BREF Scale (WHOQOL-BREF) is a generic QOL measure with four domains covering Physical, Psychological, Social and Environment. Providing the opportunity to contrast QoL with other conditions, or with population norms, the current study had three aims: 1) can the established domains of the WHOQOL-BREF be validated within a large ALS/MND population; 2) can a total score be validated and 3) can they provide interval level measurement? / Methods: Data were obtained from the Trajectories of Outcomes in Neurological Conditions study. Internal construct validity was determined by fit of the data to the Rasch measurement model. / Results: 636 participants with ALS/MND were included. All domains, except the Social domain, showed satisfactory fit to the Rasch model. All were unidimensional, and showed no Differential Item Functioning by age, gender, or onset type. Finally, a total score was validated from a bi-factor perspective. / Conclusions: The WHOQOL-BREF is valid for use in populations with ALS/MND and can be analyzed to yield interval level measurement: It offers a range of domains that reflect QOL, which can be used for parametric analysis and for comparison with other conditions or general populations, two advantages for its inclusion as a trial outcome measure and for observational studies

A comparison of the measurement properties of the Juvenile Arthritis Functional Assessment Scale with the childhood health assessment questionnaire in daily practice

We compared the measurement properties of a performance test (Juvenile Arthritis Functional Assessment Scale; JAFAS) with a questionnaire-based instrument (Childhood Health Assessment Questionnaire; CHAQ) to measure functional ability in patients with juvenile idiopathic arthritis on the level of individual items. In 28 consecutive children visiting an outpatient paediatrics clinic, the JAFAS (range 0–20) and CHAQ (range 0–3) were applied, and measures of disease activity and joint range of motion (ROM) were determined. Twenty-eight children with a median age of 10 years and median disease duration of 3.2 years were included. The median JAFAS score was 0, and the median CHAQ score was 0.125. Cronbach’s alpha was 0.92 for the JAFAS and 0.96 for the CHAQ. The Spearman correlation coefficient between the JAFAS and the CHAQ was 0.55 (P < 0.01). With six out of ten items, the JAFAS classified the child as less disabled than with corresponding CHAQ activities. Overall, associations with measures of disease activity and ROM were higher for the CHAQ than for the JAFAS. A performance test (JAFAS) does not appear to have an added benefit over the questionnaire-based assessment (CHAQ) of physical function in a cross-sectional study

Metagenomic analysis of ethylene glycol contamination in anaerobic digestion

This is the final version. Available on open access from Elsevier via the DOI in this recordData availability: Illumina WGS DNA sequence reads have been deposited in the NCBI Sequence Read Archive under BioProject accession PRJNA982105.Anaerobic digestion is an established method for the biological conversion of waste feedstocks to biogas and biomethane. While anaerobic digestion is an excellent waste management technique, it can be susceptible to toxins and pollutants from contaminated feedstocks, which may have a detrimental impact on a digester's efficiency and productivity. Ethylene glycol (EG) is readily used in the heat-transfer loops of anaerobic digestion facilities to maintain reactor temperature. Failure of the structural integrity of these heat transfer loops can cause EG to leak into the digester, potentially causing a decrease in the resultant gas yields. Batch fermentations were incubated with 0, 10, 100 and 500 ppm (parts per million) of EG, and analysis showed that the EG was completely metabolised by the digester microbiome. The concentrations of EG tested showed significant increases in gas yields, however there were no significant changes to the digester microbiome.Shell Research Ltd

Having a lot of a good thing: multiple important group memberships as a source of self-esteem.

We propose and test an identity resource model in which personal self-esteem is boosted by membership in additional important social groups. Belonging to multiple important group memberships predicts personal self-esteem in children (Study 1a), older adults (Study 1b), and former residents of a homeless shelter (Study 1c). Study 2 shows that the effects of multiple important group memberships on personal self-esteem are not reducible to number of interpersonal ties. Studies 3a and 3b provide longitudinal evidence that multiple important group memberships predict personal self-esteem over time. Studies 4 and 5 show that collective self-esteem mediates this effect, suggesting that membership in multiple important groups boosts personal self-esteem because people take pride in, and derive meaning from, important group memberships. Discussion focuses on when and why important group memberships act as a social resource that fuels personal self-esteem.This study was supported by 1.

Development and validation of Spasticity Index-Amyotrophic Lateral Sclerosis.

OBJECTIVES: Spasticity is a common and disabling feature of amyotrophic lateral sclerosis (ALS). There are currently no validated ALS-specific measures of spasticity. The aim of this study was to develop and use a self-report outcome measure for spasticity in ALS. METHODS: Following semi-structured interviews with 11 ALS patients, a draft scale was administered across ALS clinics in the UK. Internal validity of the scale was examined using the Rasch model. The numerical rating scale (NRS) for spasticity and Leeds Spasticity scale (LSS) were co-administered. The final scale was used in a path model of spasticity and quality of life. RESULTS: A total of 465 patients (mean age 64.7 years (SD 10), 59% male) with ALS participated. Spasticity was reported by 80% of subjects. A pool of 71 items representing main themes of physical symptoms, negative impact and modifying factors was subject to an iterative process of item reduction by Rasch analysis resulting in a 20-item scale-the Spasticity Index for ALS (SI-ALS)-which was unidimensional and free from differential item functioning. Moderate correlations were found with LSS and NRS-spasticity. Incorporating the latent estimate of spasticity into a path model, greater spasticity reduced quality of life and motor function; higher motor function was associated with better quality of life. CONCLUSIONS: The SI-ALS is a disease-specific self-report scale, which provides a robust interval-level measure of spasticity in ALS. Spasticity has a substantial impact on quality of life in ALS
