Motivational aspects of regular physical activity according to individual characteristics in adolescents from Viçosa-MG
No full textApesar do acesso à informação sobre Atividade Física (AF) e saúde na era digital, e da existência de inúmeros programas que incentivam a Prática Regular de Atividades Físicas (PRAF), os índices mundiais de inatividade física entre adolescentes ainda são alarmantes, ultrapassando 80%. Para enfrentar essa questão, é necessário compreender os fatores que contribuem para a inatividade física nesse grupo, incluindo aspectos biopsicossociais e motivacionais. Compreender esses aspectos pode ser a chave para identificar os fatores mais eficazes na promoção e manutenção do engajamento dos adolescentes na PRAF. Assim, o objetivo do estudo foi investigar os aspectos motivacionais para a PRAF, considerando as características individuais de adolescentes praticantes regulares de AF de Viçosa-MG. A pesquisa, envolveu 560 adolescentes de ambos os sexos, com idades entre 15 e 19 anos, regularmente matriculados no ensino médio de 10 escolas (7 públicas e 3 privadas). Foram utilizados questionários para obter dados de caracterização da amostra, dimensões e regulações motivacionais, além de serem realizadas avaliações antropométricas, para auxiliar na identificação do estado nutricional dos indivíduos. A pesquisa foi dividida em dois artigos originais, ambos com análise inferencial. Após análise de normalidade dos dados, foram utilizados os testes estatísticos U – Mann Whitney, Kruskal-Wallis com post hoc de Dunn e a Correlação de Spearman. O nível de significância adotado foi de α=5%. No primeiro artigo, observou-se que 36,6% dos adolescentes foram categorizados como insuficientemente ativos, apesar de serem praticantes regulares de AF. Além disso, 73,6% foram classificados como eutróficos. Houve diferenças nas preferências de AF entre os sexos, com os rapazes praticando uma variedade maior de modalidades de AF. Em relação à quantidade de tipos de AF praticadas, houve equidade entre os sexos, com a maioria praticando principalmente um tipo de AF, geralmente em ambientes fechados. As dimensões Prazer (PR), Saúde (SA) e Estética (ES) foram as mais importantes para a PRAF, enquanto a Competitividade (CO) foi a menos relevante, independentemente das características individuais. No segundo artigo, as correlações entre as regulações motivacionais apresentaram padrões diferentes conforme cada característica individual. As moças apresentaram correlações mais fortes entre as regulações mais autônomas, destacando a autonomia e a internalização do comportamento a PRAF. A amotivação correlacionou-se negativamente com regulações mais autônomas entre os sexos. Nos grupos etários, os rapazes apresentaram um padrão correlacional parecido, com diferença apenas na força de correlação entre a regulação externa e introjetada. As moças mais jovens apresentaram correlações e magnitudes maiores do que as mais velhas, particularmente entre amotivação e as demais regulações. Descobertas recentes destacam a importância de considerar grupos etários e regulações motivacionais específicas ao incentivar a PRAF entre adolescentes de acordo com suas características individuais. Além disso, os resultados indicam que a motivação para a PRAF varia conforme o estado nutricional em cada sexo, reforçando a necessidade de estratégias personalizadas para minimizar a evasão da AF regular e incentivando comportamentos motivados mais autônomos na PRAF entre adolescentes.

Estado nutricional.Despite access to information about Physical Activity (PA) and health in the digital age, and the existence of numerous programs that encourage the Regular Practice of Physical Activities (RPPA), global rates of physical inactivity among adolescents are still alarming, exceeding 80%. To address this issue, it is necessary to understand the factors that contribute to physical inactivity in this group, including biopsychosocial and motivational aspects. Understanding these aspects may be key to identifying the most effective factors in promoting and maintaining adolescents’ engagement in RPPA. Thus, the aim of the study was to investigate the motivational aspects for RPPA, considering the individual characteristics of adolescents who are regular PA practitioners in Viçosa-MG. The research involved 560 adolescents of both sexes, aged between 15 and 19 years, regularly enrolled in high school in 10 schools (7 public and 3 private). Questionnaires were used to obtain data on sample characterization, motivational dimensions and regulations, and anthropometric assessments were carried out to help identify the nutritional status of individuals. The research was divided into two original articles, both with inferential analysis. After normality analysis of the data, the statistical tests U – Mann Whitney, Kruskal-Wallis with Dunn’s post hoc, and Spearman’s Correlation were used. The significance level adopted was α=5%. In the first article, it was observed that 36.6% of the adolescents were categorized as insufficiently active, despite being regular PA practitioners. Additionally, 73.6% were classified as eutrophic. There were differences in PA preferences between sexes, with boys practicing a greater variety of PA modalities. Regarding the number of types of PA practiced, there was equity between sexes, with most practicing mainly one type of PA, usually indoors. The dimensions Pleasure (PL), Health (HE), and Aesthetics (AE) were the most important for RPPA, while Competitiveness (CO) was the least relevant, regardless of individual characteristics. In the second article, correlations between motivational regulations showed different patterns according to each individual characteristic. Girls showed stronger correlations between more autonomous regulations, highlighting autonomy and the internalization of behavior towards RPPA. Amotivation was negatively correlated with more autonomous regulations between sexes. In age groups, boys showed a similar correlational pattern, with only a difference in the strength of correlation between external and introjected regulation. Younger girls showed higher correlations and magnitudes than older ones, particularly between amotivation and other regulations. Recent findings highlight the importance of considering age groups and specific motivational regulations when encouraging RPPA among adolescents according to their individual characteristics. Additionally, the results indicate that motivation for RPPA varies according to nutritional status in each sex, reinforcing the need for personalized strategies to minimize dropout from regular PA and encouraging more autonomous motivated behaviors in RPPA among adolescents.

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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
