Percepção sobre o uso do narguilé e do cigarro eletrônico entre jovens adultos do estado de São Paulo: utilização e consequências à saúde dos usuários
Full text linkIntrodução: Em usuários regulares de narguilé, é possível observar níveis de monóxido de carbono (CO) e carboxihemoglobina (COHb) elevados, tanto para sessões que utilizam tabaco e nicotina, quanto para sessões livres desses componentes. Esta observação sugere que a exposição ao CO no uso de narguilé está relacionada ao carvão usado para aquecer o tabaco e reforça ainda mais a alegação de que a ausência de tabaco não torna o narguilé seguro. Com base nesses dados, é possível observar que o uso desses dispositivos pode acarretar em um risco maior para o desenvolvimento de DPOC. Os sintomas respiratórios como tosse, secreção e dispnéia, se associam com a dependência e o grau de comprometimento respiratório, observando que quanto maior o grau dependência, mais evidentes os sintomas são relatados. Objetivo: O objetivo do estudo foi analisar o comportamento dos jovens do estado de São Paulo diante do uso do narguilé e dos cigarros eletrônicos. Verificar a frequência do uso desses dispositivos, o conhecimento dos jovens acerca dos efeitos fisiológicos do uso desses dispositivos e as consequências para a saúde. Método: Trata-se de estudo observacional prospectivo onde foi aplicado um questionário para levantamento de informações sobre o uso do narguilé e cigarro eletrônico entre jovens do estado de São Paulo. Conclusão: O hábito de fumar esses dispositivos é frequente e já está presente no dia a dia das pessoas, principalmente dos jovens, como forma de interação social. Mesmo possuindo conhecimento acerca dos riscos à saúde promovidos por esses dispositivos e já tendo experimentado algum efeito adverso durante e/ou após a sessão de fumo, os usuários continuam fazendo seu uso. Isso reforça a necessidade de campanhas de políticas públicas de saúde enfatizando as consequências à exposição ao fumo dos cigarros eletrônicos e dos narguilésIntroduction: For regular hookah users, it’s possible to observe high levels of carbon monoxide (CO) e carboxyhemoglobin (COHb), both for sessions using tobacco e nicotine, and for the sessions free from these components. This observation suggests that CO exposure during hookah usage is related to the coal used to heat the tobacco, and, endorses the claim related to the fact that absence of tobacco does not make hookah safe. Based on this information, it is possible to observe that using these devices can lead to a greater risk of COPD (Chronic Obstructive Pulmonary Disease). Respiratory symptoms such as cough, phlegm production and shortness of breath, are related to addiction and the commitment levels, since the observations show that the greater the addiction levels, the more evident the symptoms are observed. Specific Goals: This study aimed to analyze the Youth behavior in São Paulo State regarding hookah usage and electronic cigarettes. Checking the frequency of use of these devices, the knowledge about physiological side-effects of using them and possible consequences in their health. Method: This is a prospective observational study which a survey will be applied to collect data regarding the hookah and electronic cigarettes usage among young people in São Paulo state. Conclusion: The smoking habits considering these devices are usual and have already been included in people’s routines, especially for young people as a social interaction strategy. Even having knowledge about the side effects during and/or after the smoking session, users continue to use them. This strengthens the need for public health policy campaigns emphasizing the consequences of exposure to electronic cigarettes and hookah smok
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
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

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.
