ABSTRACT Studies that have analysed the association between the different movement behaviours and fundamental movement skills (FMS) have considered it in an independent manner, disregarding the compositional nature of 24-h movement behaviours (24-h MB). The aim of this study was to investigate the relationship between the 24-h MB and FMS in preschoolers using a compositional data analysis . Two hundred and four preschoolers (4.5 ± 0.8 years old; 101 boys) provided objectively assessed physical activity (PA) and sedentary behaviour (SB) data (Actigraph wGT3X), and FMS (TGMD-2). Sleep duration (SD) was reported by parents. Association of daily composition of movement behaviours with FMS was explored using compositional analysis and isotemporal substitution (R Core Team, 3.6.1). When considered as a 24-h MB composition (PA, SB and SD), adjusted for age, BMI and sex, the composition predicted locomotor (r2 = 0.31), object control (r2 = 0.19), and total motor score (r2 = 0.35), respectively (all P < 0.001). Reallocation of time from light to moderate-to-vigorous PA was associated with greatest positive changes in total motor score. Achieving adequate balance between movement behaviours over the 24-h period, and its relationship with locomotor and object control skills should be considered and further investigated in early childhood. 相似文献

The Winsor & NewtonTM (W&N) nineteenth century archive database includes digitised images of hand-written instructions and workshop notes for the manufacture of their artists’ materials. For the first time, all 183 production records for yellow lead chromate pigments were studied and evaluated. They revealed that W&N produced essentially three pigment types: lemon/pale based on mixed crystals of lead chromate and lead sulphate [Pb(Cr,S)O4]; middle on pure monoclinic lead chromate [PbCrO4]; and deep that contains the latter admixed with basic lead chromate [Pb2CrO5]; accounting for 53, 22, and 21% of the production, respectively. Production records for primrose (4%) were also included since the formulation results in mixed crystals with a high percentage of lead sulphate, which, according to the literature, leaves it more prone to degradation. Each pigment type is characterised by only one or two main synthetic pathways; process variations reveal a systematic and thorough search for a high-quality durable product. A comparison of the chemical composition of pigment reconstructions with early W&N oil paint tubes showed that their records entitled ‘pale’ and ‘lemon’ correlated with the pigment in their tube labelled chrome yellow and, ‘middle’ and ‘deep’ with the label chrome deep. Lemon and middle pigment formulations were made into oil paints to assess their relative photo-stability. The degradation process was followed by colorimetry and was studied by synchrotron radiation-based techniques. Based on the X-ray absorption spectroscopy data, the possibility for creating a stability index for chrome yellows is discussed. 相似文献

Despite global demand, the large-scale effects of social-emotional learning (SEL) programming in developing countries remain underexplored. Using a randomized control trial, this study examined the effectiveness of a school-wide SEL intervention—Programa Compasso (PC)—among 3,018 sociodemographically diverse, Portuguese-speaking children (Mage = 9.85 years) attending 90 public primary schools across Rio de Janeiro, Brazil in 2017. Average impacts of PC on children’s executive function, emotion knowledge, and behavior problems after one school year were null. Moderation analyses did, however, reveal evidence for positive impacts of PC on children’s labeling of emotional expressions and inhibitory control within low-homicide communities (d = 0.15 SDs), and null effects on these same outcomes in high-violence areas. Implementation and cultural considerations are discussed. 相似文献

The aim of the present study is twofold: (1) contribute to identifying a model for the variables that compose the emergent
literacy construct and their relationships; (2) assess the predictive power of the emergent literacy model on early writing
abilities in a transparent orthography language.
We examined emergent literacy skills in 464 children (mean age 5.5, range: 48–6.1) who were followed longitudinally until
entering the 1st grade in primary school. Exploratory and Confirmatory factor analyses were used to address questions on the
nature of emergent literacy skills and their possible relationships. Regression analyses were implemented to evaluate the
predictive capability of an emergent literacy model on word writing competences. The factor analyses showed three factorial
dimensions (phonological, conceptual knowledge on writing system and textual) and their relationship. The regressions showed
a significant prediction of conceptual knowledge on writing system and of phonological abilities on early writing abilities. 相似文献

Isokinetic hamstring-to-quadriceps (H:Q) ratios are frequently used to assess knee muscle strength imbalances and risk of injuries/re-injuries. The use of peak torque (PT) or total work (TW) to estimate joint stability may lead to different results because of the differences between these two neuromuscular variables. Thus, the current study aimed to compare the conventional and functional H:Q ratios calculated by PT and TW. Ninety-three male professional soccer players from Brazilian first division teams performed isokinetic concentric and eccentric contractions of the quadriceps and the hamstrings at 60°/s. Muscle strength balance was calculated using the conventional torque ratio (CTR) and conventional work ratio (CWR), functional torque ratio (FTR) and functional work ratio (FWR) were highly and moderately correlated between them (r?=?0.83 and r?=?0.73, respectively). The Wilcoxon statistical test revealed significant differences between CTR and CWR, as well as FTR and FWR (p?0.05). T-test demonstrated significant differences in mean CTR–CWR and FTR–FWR, whereas Bland–Altman plots showed non-consistent bias. In addition, the chi-square test demonstrated significant differences between players below the conventional reference values and functional reference values (p?0.001). In conclusion, TW ratios seem to provide distinct and additional information regarding the H:Q strength balance in professional soccer players. Moreover, taking into account that TW captures torque information throughout the entire range of motion, it is possible that TW ratios represent a more comprehensive assessment of muscle strength imbalance. 相似文献

The aim of the present research is to assess the developmental pattern of the metacognitive knowledge of attention in Italian primary school students. Data were collected from 95 pupils divided into two age groups: the first (6–8 years) and second primary school cycles (8–10 years). The children were asked to perform two specific thematic drawings on attention vs inattention in the school context. The drawings were coded on the basis of the Children’s Awareness of Attention through Drawing, consisting of five scales which explore the behavioural, pragmatic, cognitive, emotional and social awareness of attention. The analysis of the thematic drawings reveals that from the early years of primary school, children are aware of some components of attention: behavioural awareness, pragmatic awareness and social awareness. Other components are instead acquired as of the age of eight. 相似文献

The article presents a study on metalinguistic, cognitive and metacognitive abilities in university students. A sample of
353 students was recruited; 178 of which from scientific and 175 from humanistic Faculties, with gender balance (M = 178;
F = 175) whose age range was between 20 and 25 years old. They were administered a metalinguistic ability test that assesses
metalinguistic awareness at implicit and explicit levels (L and ML scores) and the Raven’s Standard Progressive Matrices 38
(SPM38). In addition to the usual nonverbal administration of the matrices, candidates were asked to justify in written form
the reasons for the solution indicated in each item. Three scores were considered for the SPM38: the ordinary score based
on the number of correct nonverbal solutions (O.S.), a 7-point scale for assessing the argumentation of the correct solutions
(C.ARG.S.) and a 6-point scale for assessing the argumentation of the incorrect solutions (I.ARG.S.). Significant gender and
curriculum effects were found, with males and scientific students dominating at the nonverbal level while females and humanistic
students dominated in the argumentative abilities related to the matrices and in all the scores of the metalinguistic test.
A number of significant correlations were found between all the metalinguistic, cognitive and metacognitive abilities considered,
with a prominent role of the metalinguistic abilities at the explicit level (ML score) that show a clear argumentative structure
very similar to the C.ARG.S. argumentations in the matrices test. 相似文献
