Exploring the interplay between physical activity levels, motor performance and BMI in children and adolescents: insights from the motor abilities observatory in Puglia
Full text linkSedentary habits stand out as primary contributors to the decline in physical activity levels and motor performance during childhood. Physical activity (PA) promotes the development of motor abilities, the acquisition of motor competencies, and provides preventative and protective effects against various non communicable diseases. Alarmingly, children and adolescents in Italy are falling short of complying with the World Health Organization's (WHO) recommendations for daily physical activity essential for promoting optimal health. This study aimed to assess and compare the physical activity levels and motor performance of a cohort comprising 313 children (M, age: 9.43 ± 0.79 years; F, age: 9.48 ± 0.60 years) and 313 adolescents (M, age: 11.89 ± 0.90 years; F, age: 11.86 ± 0.84 years). The participants were divided into subgroups based on variations in Body Mass Index (BMI). Utilizing a self-report tool (PAQ_C) and two motor tests, our aim was to evaluate the trends in physical activity and motor capabilities. The findings confirmed a significant decline in physical activity levels from childhood to adolescence, coupled with suboptimal motor performance in overweight and obese students. This article presents the initial outcomes of a regional investigation into the assessment of physical activity levels and motor abilities concerning gender and BMI variations among primary and middle school students in Puglia. The identified reduction in physical activity underscores the urgency for inter-institutional initiatives and multicomponent projects. These initiatives should emphasize the pivotal role of relationships between family, school, and sports in addressing and mitigating the alarming decline in physical activity levels among the youth
Analysis of self-perceived use of spectrum of teaching styles in Italian physical education teachers
Full text linkIntroductionThe present study aims to assess PE teachers' perception about the use of teaching styles during curricular lessons.MethodsThe sample involved a total of 83 PE teachers (M = 41, F = 42, main age = 43,74 ± 10,76) divided according to years of service (0–4 = 36%, 5–10 = 34%, and over 10 = 30%) and academic training (Higher Institutes of Physical Education = 44% and master's degree = 56%). Teachers complete a digitalized version of a self-produced questionnaire to assess how many times they use each teaching styles during the last month.ResultsResults show that (a) reproduction rather than production teaching styles were often used, while reproduction teachings styles were most frequently used regardless of years of service.DiscussionFuture research should investigate PE teacher's behavior to enhance the quality of physical education in school
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“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
Full text linkWe 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
PHYSICAL ACTIVITY LEVELS AND PHYSICAL FITNESS IN ADOLESCENTS: IMPLICATIONS FOR TEACHING
Full text linkRegular physical activity promotes health by enhancing physical fitness (PF) in adolescents; however, daily physical activity levels (PAL) are often insufficient. This study analyzes the relationship between PAL and PF, highlighting positive correlations with cardiovascular and muscular efficiency. An active lifestyle is confirmed as a key determinant of PF during adolescence, and schools can play a crucial role in promoting adolescent health
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
