Mapping relationships among gross motor skills in 16,989 children using network analysis
Get PDFThe development of gross motor skills during childhood is crucial for shaping more complex movements and laying the groundwork for physical activity, and subsequently lifelong health and enhanced well-being. Performance in motor skills improves throughout development, with the greatest improvements occurring during childhood. Understanding the relationships between developing gross motor skills is essential for informing educational and intervention practices. A total of 16,989 children aged 3–11 years underwent assessment of gross motor skills. Using network analysis, gross motor skills networks were constructed for the entire sample, and stratified by age and sex. The accuracy and stability of the networks were assessed, and centrality and bridge statistics were estimated for each node. The results indicated that running and two-hand catching exhibited higher centrality and bridge statistics compared to the other nodes in the all-sample network. Additionally, it was observed that the strength between nodes decreased and their distance increased with age. These results highlight the importance of specific gross motor skills due to their significant role in relation to other skills within the network. Gross motor skills progress towards increased independence and specialisation during development, indicating the importance of early educational interventions where children could benefit from educational practices focused on catching and running
Normative percentile values for the TGMD-3 for Italian children aged 3--11+ years
No full textObjectives: sufficient gross motor skill proficiency is an essential prerequisite for the successful performance of sport-specific skills and physical activities. The Test of Gross Motor Development is the most common tool for assessing motor skills in paediatric populations, however, there is a lack of ‘normative’ data available against which children's scores can be compared. Normative data would enable the comparison of an individual's motor development to age-standardised norms. The aim of this study was to develop normative data for the Test of Gross Motor Development Third Edition scores for Italian children. Design: The Test of Gross Motor Development Third Edition scores from > 17,000 Italian children (aged 3–11 + years) were analysed to develop normative scores and percentiles. Methods: Total Test of Gross Motor Development Third Edition scores and locomotor and ball skills subscale scores were split by age and sex. Using the LMS method, based on the Box-Cox transformation, percentiles were calculated for each sex-specific age category. Results: 17,026 children were included in the analysis (n = 8262 girls; n = 8766 boys). Conclusions: this is the largest sample ever used to develop normative data for the Test of Gross Motor Development and the first set of normative data for European children. This normative data can be used to identity insufficient motor skill development and aid subsequent modification of activities to nurture sufficient motor skill proficiency. This is particularly important for children in the lower percentiles given the strong associations between early childhood fundamental motor skill competence and physical activity participation in adolescence and adulthood.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Differences in self-control, self-efficacy and depressive symptoms between active and inactive middle-aged and older adults after 1 year of COVID restrictions
Get PDFObjectives: The psychological impact of the prolonged lockdown measures in the UK as a response to the COVID-19 pandemic is unclear. Our aim was to determine if there are significant differences in self-control, self-efficacy, depressive symptoms and leisure motivation between UK older adults with differing levels of physical activity, and which of these variables can be used to predict activity level after 1 year of lockdown restrictions,
Methods: 521 adults aged 50–92 years completed an online survey consisting of several validated measures relating to physical activity, self-control, self-efficacy, depressive symptoms, and leisure motivation. Participant’s responses were grouped into active (≥150minutes activity per week) and inactive (<150minutes activity per week). Data was analysed using ANOVA, Pearson’s Correlation and Multiple Regression (forward stepwise).
Results: We found significant differences in self-efficacy, self-control, and depressive symptoms between physically active vs inactive subjects. High levels of self-control and self-efficacy were associated with higher levels of activity and fewer depressive symptoms. Self-control, amotivation, depressive symptoms and self-efficacy were predictors of physical activity level.
Conclusion: Psychological variables including self-control, self-efficacy, depressive symptoms and amotivation can be used to predict physical activity levels in UK middle-aged and older adults following 1 year of Covid restrictions
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
