Self-regulated learning:Validating a task-specific questionnaire for children in elementary school

This paper describes the development and initial validation of the Cognition and Emotion/Motivation Regulation (CEMOR) questionnaire, a task-specific questionnaire for upper elementary school students that measures self-regulated learning (SRL). Using a multistep procedure, 22 items were developed, divided over five theory-informed dimensions (Planning, Monitoring, Cognition Control, Emotion/Motivation Control, and Reflecting). The CEMOR was applied in a math context. Children from grades 3–6 (N = 547, 54.7 % females) completed the CEMOR. Confirmatory factor analyses indicated that the five proposed scales have adequate to good model fit, with factor loadings ranging from .54 to .83, and acceptable to good composite reliability (ρ range = .75–.85). To find further validity support, the SRL scales were correlated with students’ performance on a math task, experienced emotions, and level of motivation during the task. Most correlations were statistically significant and in the expected direction. Hence, the CEMOR questionnaire shows promise as a new SRL instrument for elementary education

Addressing Endogeneity in International Marketing Applications of Partial Least Squares Structural Equation Modeling

Partial least squares structural equation modeling (PLS-SEM) has become a key method in international marketing research. Users of PLS-SEM have, however, largely overlooked the issue of endogeneity, which has become an integral component of regression analysis applications. This lack of attention is surprising because the PLS-SEM method is grounded in regression analysis, for which numerous approaches for handling endogeneity have been proposed. To identify and treat endogeneity, and create awareness of how to deal with this issue, this study introduces a systematic procedure that translates control variables, instrumental variables, and Gaussian copulas into a PLS-SEM framework. We illustrate the procedure's efficacy by means of empirical data and offer recommendations to guide international marketing researchers on how to effectively address endogeneity concerns in their PLS-SEM analyses

Genomics and metagenomics of trimethylamine-utilizing Archaea in the human gut microbiome

International audienceThe biological significance of Archaea in the human gut microbiota is largely unclear. We recently reported genomic and biochemical analyses of the Methanomassiliicoccales, a novel order of methanogenic Archaea dwelling in soil and the animal digestive tract. We now show that these Methanomassiliicoccales are present in published microbiome data sets from eight countries. They are represented by five Operational Taxonomic Units present in at least four cohorts and phylogenetically distributed into two clades. Genes for utilizing trimethylamine (TMA), a bacterial precursor to an atherosclerogenic human metabolite, were present in four of the six novel Methanomassiliicoccales genomes assembled from ELDERMET metagenomes. In addition to increased microbiota TMA production capacity in long-term residential care subjects, abundance of TMA-utilizing Methanomassiliicoccales correlated positively with bacterial gene count for TMA production and negatively with fecal TMA concentrations. The two large Methanomassiliicoccales clades have opposite correlations with host health status in the ELDERMET cohort and putative distinct genomic signatures for gut adaptation

Post-COVID-19 patients in geriatric rehabilitation substantially recover in daily functioning and quality of life

BackgroundAfter an acute infection, older persons may benefit from geriatric rehabilitation (GR).ObjectivesThis study describes the recovery trajectories of post-COVID-19 patients undergoing GR and explores whether frailty is associated with recovery.DesignMulticentre prospective cohort study.Setting59 GR facilities in 10 European countries.ParticipantsPost-COVID-19 patients admitted to GR between October 2020 and October 2021.MethodsPatients’ characteristics, daily functioning (Barthel index; BI), quality of life (QoL; EQ-5D-5L) and frailty (Clinical Frailty Scale; CFS) were collected at admission, discharge, 6 weeks and 6 months after discharge. We used linear mixed models to examine the trajectories of daily functioning and QoL.Results723 participants were included with a mean age of 75 (SD: 9.91) years. Most participants were pre-frail to frail (median [interquartile range] CFS 6.0 [5.0–7.0]) at admission. After admission, the BI first steeply increased from 11.31 with 2.51 (SE 0.15, P P P P ConclusionsPost-COVID-19 patients admitted to GR showed substantial recovery in daily functioning and QoL. Frailty at GR admission was not associated with recovery and should not be a reason to exclude patients from GR.Public Health and primary careGeriatrics in primary car
