- Background/ObjectiveThe Everyday Technology Use Questionnaire (ETUQ), which evaluates the perceived relevance of and the perceived ability in everyday technology (ET) use, has demonstrated acceptable psychometric properties in Swedish studies of older adults. The aim of this study was to examine the reliability and validity of the ETUQ in a Japanese context in older Japanese adults.MethodsA sample of older Japanese adults (n = 164) including persons with (n = 32) and without (n = 132) cognitive impairment was interviewed with the ETUQ, including original items (ETs) and added Japanese context-specific items. Data were analyzed using a Rasch measurement model.ResultsThe analysis demonstrated acceptable functioning of the rating scale, internal scale validity, person response validity, and person-separation reliability of the Japanese ETUQ according to the Rasch model. However, evidence supporting unidimensionality in the Japanese ETUQ was not consistent in this sample. The added Japanese items did not significantly change the estimated individual person measures of perceived ability to use ET.ConclusionThe Japanese ETUQ seems to be a sensitive tool to evaluate perceived ability in ET use among elderly people in Japan with and without cognitive impairment. Therefore, it could be used in research and clinical practice.

- Background: Validated outcome measures are essential for assessment and treatment of children with disabilities. The Children's Hand-use Experience Questionnaire (CHEQ) was developed and validated for use in Western countries for children with unilateral hand dysfunction. This study aimed to perform a cross-cultural adaptation and investigate reliability for the Arabic CHEQ.Methods: Translation and cross-cultural adaptation were performed in four phases: (i) forward-translation and reconciliation with feedback from parents and typically developing children from Jordan (n = 14); (ii) backward-translation and review; (iii) cognitive debriefing with parents and/or their children with unilateral hand dysfunction (n = 17); and (iv) review and proofreading. In the psychometric analyses, 161 children from Jordan (mean age [SD] 10y 8 m [5y 8 m]; 88 males) participated. Internal consistency was evaluated with Cronbach's alpha. Test-retest reliability was evaluated in 39 children with intraclass correlation coefficient (ICC) and weighted kappa (kappa).Results: Synonyms of four words were added to accommodate for different Arabic dialects. On average, 93% of children with unilateral hand dysfunction and their parents understood the CHEQ items. One response alternative, 'Get help', to the opening question was unclear for 70% of the respondents and need further explanation. Two items about using a knife and fork were difficult to comprehend and culturally irrelevant. High internal consistency was demonstrated (Cronbach's alphas 0.94- 0.97) and moderate to excellent ICC (0.77-0.93). For 18 individual items, kappa indicated poor to good agreement (kappa between 0.28 and 0.66).Conclusions: After the suggested minor adjustments, the Arabic CHEQ will be comprehensible, culturally relevant and reliable for assessing children with unilateral hand dysfunction in Jordan.

- Together with fungi, saprophytic bacteria are central to the decomposition and recycling of biomass in forest environments. The Bacteroidetes phylum is abundant in diverse habitats, and several species have been shown to be able to deconstruct a wide variety of complex carbohydrates. The genus Chid/lop/lap is often enriched in hotspots of plant and microbial biomass degradation. We present a proteomic assessment of the ability of Chitinophaga pinensis to grow on and degrade mannan polysaccharides, using an agarose plate-based method of protein collection to minimise contamination with exopolysaccharides and proteins from lysed cells, and to reflect the realistic setting of growth on a solid surface. We show that select Polysaccharide Utilisation Loci (PULs) are expressed in different growth conditions, and identify enzymes that may be involved in mannan degradation. By comparing proteomic and enzymatic profiles, we show evidence for the induced expression of enzymes and PULs in cells grown on mannan polysaccharides compared with cells grown on glucose. In addition, we show that the secretion of putative biomass-degrading enzymes during growth on glucose comprises a system for nutrient scavenging, which employs constitutively produced enzymes. Significance of this study: Chitinophaga pinensis belongs to a bacterial genus which is prominent in microbial communities in agricultural and forest environments, where plant and fungal biomass is intensively degraded. Such degradation is hugely significant in the recycling of carbon in the natural environment, and the enzymes responsible are of biotechnological relevance in emerging technologies involving the deconstruction of plant cell wall material. The bacterium has a comparatively large genome, which includes many uncharacterised carbohydrate -active enzymes. We present the first proteomic assessment of the biomass-degrading machinery of this species, focusing on mannan, an abundant plant cell wall hemicellulose. Our findings include the identification of several novel enzymes, which are promising targets for future biochemical characterisation. In addition, the data indicate the expression of specific Polysaccharide Utilisation Loci. induced in the presence of different growth substrates. We also highlight how a constitutive secretion of enzymes which deconstruct microbial biomass likely forms part of a nutrient scavenging process. (C) 2017 Elsevier B.V. All rights reseivecl.
