    INTRODUÇÃO: A atividade física (AF) é reconhecida como uma boa alternativa de prevenção de doenças e promoção do bem-estar físico, mental e social das populações. Não obstante esse consenso, os programas de AF para idosos têm dificuldades para encontrar métodos que sejam capazes de proporcionar, simultaneamente, eficácia nos efeitos desejados e permanência dos participantes. OBJETIVO: comparar a aquisição, a retenção e a permanência dos efeitos biopsicossociais de dois modelos de intervenção de AF para idosas em Moçambique. MÉTODO: um grupo de 69 mulheres idosas com idade igual ou superior a 60 anos participaram do estudo, tendo sido criteriosamente selecionadas e aleatoriamente distribuídas para dois grupos: Formal (prática de atividades físicas formais) e Lúdico (prática de atividades lúdicas). A intervenção foi realizada em duas fases e as aulas tiveram frequência de 3 vezes por semana em dias alternados (segundas, quartas e sextas feiras), sessões diárias de uma hora de duração e orientadas por monitores credenciados. Na primeira fase (Fase 1) que durou 12 semanas, o Grupo Formal (n=35) realizou sessões de 20 minutos de trabalho aeróbio em cicloergômetro com intensidade de esforço controlada de 65 à 85% da frequência cardíaca máxima (FCmáx.), mais 8 exercícios de resistência muscular com 15 repetições máximas (RM) enquanto o Grupo Lúdico (n=34) realizou atividades físicas de caráter lúdico compostas por jogos, atividades recreativas ativas incluindo danças tradicionais. Na segunda fase (Fase 2) que durou 8 semanas, cada grupo foi subdividido em dois subgrupos que combinados resultaram na formação de 4 subgrupos: Formal (n=18/14); Lúdico (n=17/15); Formal + Lúdico (ForLuD; n=17/14) e Lúdico + Formal (LudFor; n=17/16). Um dos subgrupos continuou a realizar o mesmo tipo de atividade da fase 1 (retenção), enquanto o outro realizou AF que antes não tinha realizado (permanência). Antes do início da intervenção e no final de cada fase as participantes foram submetidas aos mesmos testes (pré; pós1 e pós2) que incluía: (1) antropometria (peso, altura, perímetro da cintura e porcentagem da gordura por bioimpedância); (2) fatores de risco de doença cardiovascular (pressão arterial sistólica e diastólica; glicemia; colesterol, lipoproteína de alta densidade e triglicerídeos); (3) teste de aptidão física de Rikli e Jones (1999) (sentar e levantar; rosca; sentar e alcançar; agilidade e caminhada); (4) nível da atividade física habitual (acelerômetro por 7 dias) e (5) variáveis psicossociais (autoeficácia; autopercepção do desempenho; autoestima, autoimagem e motivação intrínseca). Os dados foram analisados no SPSS.20 com 95% de intervalo de confiança e obedeceu aos pressupostos da normalidade de dados (ANOVA mista) e não normalidade (Mann-Whitney, Wilcoxon e Qui quadrado). RESULTADOS: As participantes apresentaram elevada prevalência de risco de saúde no início do estudo, quadro que permaneceu até o final da intervenção. Na fase de aquisição ambos os grupos melhoraram a capacidade cardiorrespiratória e aumentaram o nível de confiança em continuar a participar do programa. Na retenção e na permanência todos os subgrupos diminuíram a porcentagem de gordura corporal e melhoraram a agilidade. Não houve diferença estatisticamente significante na comparação intergrupos (na aquisição) e intersubgrupos (na retenção e na permanência). CONCLUSÃO: Os dois modelos de intervenção foram similares nos efeitos biopsicossociais da AF, o que permite sugerir que o modelo lúdico é uma alternativa real e viável de programa de intervenção para idosas moçambicanas, consideradas as condições culturais, sociais e econômicas do paísINTRODUCTION: Physical activity (PA) is recognized as a good alternative to prevent disease and to promote populations physical, mental and social well being. Beside this agreement, PA programs for the elderly have faced difficulties to find methods that can congregate the efficacy of the effects and the permanence of people on the program. OBJECTIVE: the aim of this study was to compare the acquisition, retention and permanence of biopsychosocial effects of two types of PA program for Mozambican older women. METHOD: 69 older women (>=60 years old) were randomlly distributed to two groups: FAG (formal activity group) and LAG (ludic activity group). The intervention program was carried out in two phases with 3 practice sessions (one hour of duration) per week (Mondays, Wednesdays and Fridays), and were oriented by credited trainers. The first phase of the study lasted 12 weeks and the participants of FAG (n=35) practiced 20 min of aerobic work on the treadmill with standard intensity control procedure (65 to 85% HR max) followed by 8 muscular endurance exercises with 15 maxim repetitions (RM). On the other hand participants of LAG (n=34) practiced games, dance and recreational activities. On the second phase, the study had 8 weeks of practice, and both groups were further divided into 2 sub-groups whose combination resulted in 4 sub-groups: Formal activity (FFAG; n=18/14); Ludic activity (LLAG; n=17/15); Formal+Ludic activity (FLAG; n=17/14) and Ludic+Formal activity (LFAG; n=17/16). Two of the sub-groups continued to practice the same activity of the first phase and another two sub-groups changed to the activities practiced by the other group in the first phase. The participants were submitted to the anthropometry test batteries (weight, height, west and body fat) and risk factor of cardiovascular disease test (systolic blood press and diastolic blood press; glycemic; cholesterol; high-density lipoprotein and triglycerides). Additionally they were submitted to fitness test (chair stand; arm curl; chair sit-and-reach; 8-foot up-and-go and 6-minute walk), physical activity level test (by accelerometer for seven consecutive days) and psychosocial factors test (self-efficacy; self-perception skill, self-esteem; self-image and intrinsic motivation). The data were analyzed by SPSS.20 with 95% of confidence interval. When normality criterion was achieved parametric test was used (mixed ANOVA) and nonparametric tests (Mann-Whitney, Wilcoxon and X square tests) were used when normality criterion was not achieved. RESULTS: the participants showed high level of health risk factor from the beginning to the end of the intervention. In the acquisition all groups improved the cardiorespiratory fitness and the level of the confidence to continue on the PA program. In the retention and permanence, all sub-groups reduced the level of body fat and improved agility. Inter-group comparisons reveled no statistical difference between groups (acquisition) and sub-groups (retention and permanence). CONCLUSION: The two types of PA program were similar in acquisition, retention and permanence of the biopsychosocial effects. Thus, it can be suggested that the ludic model of PA program is a real and viable alternative program for Mozambican older women, especially taking into account the cultural, social and economic conditions of the countr

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    We 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 text
    In 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.
