Fatores associados ao consumo de tabaco em adolescentes escolares da região sul do Brasil
No full textIntrodução: O tabaco é considerado pela Organização Mundial de Saúde como uma das principais causas evitáveis de morte. Na adolescência ocorre uma grande exposição e vulnerabilidade para experimentação e uso do tabaco. Objetivo: Avaliar os fatores associados ao consumo de tabaco entre adolescentes escolares da Região Sul do Brasil. Metodologia: Estudo transversal a partir dos microdados da pesquisa Nacional de Saúde do Escolar (PENSE), 2015. Os participantes foram adolescentes de 13 a 19 anos, de escolas públicas e privadas do Sul do Brasil. Teste Qui-quadrado, p < 0,05. Aprovado por Comitê de Ética. Resultados: 2305 pesquisados; prevalência de experimentação de fumo de 28,8%, com idade média de 13 anos, e uso nos últimos 30 dias em 7,8%. Entre os que experimentaram, 28,9% com consumo recente de tabaco. Associação com não morar com pai (RP 1,35;IC95 1,064-1,913;p=0,014), pais que fumam (RP 1,528;IC95 1,082-2,156.;p=0,016), presença de pessoas que fumam (RP 2,151; IC95 1,514-3,058; p<0,001), consumo de álcool nos últimos 30 dias (RP 3,274; IC95 2,072-5,173; p<0,001), experimentação de drogas (RP 2,043; IC 1,537-2,650; p<0,001), uso de drogas nos últimos 30 dias (RP 3,355; IC95 2,418-4,653; p<0,01) e sexarca (RP 1,622; IC95 1,197-2,198; p=0,001).Conclusão: O contexto/convívio familiar, uso de outra drogas e a influência de fatores comportamentais podem aumentar o consumo de tabaco entre adolescentes
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
KNOWLEDGE ON MEDICAL PLANTS IN USERS OF A PSYCHOSOCIAL CARE CENTER AND DRUGS
No full textObjective: To evaluate the knowledge about medicinal plants and their uses among patients of the Psychosocial Care Center for Alcohol and Drugs in the municipality of Palhoça. Methods: Cross-sectional study involving 88 participants of both sex and different ages who were in Psychosocial Care Center for Alcohol and Drugs between February and June 2019, through the application of a questionnaire and information collected from their medical records. Data analyzed by descriptive statistics. Results: Mean age 42 years, male gender (64.8%), white ethnicity (72.7%), alcohol abuse (72.7%), cocaine (44.3%), marijuana (35.2%) and 22.7% crack (22.7%). There was a high prevalence of the use of medicinal plants (93.2%), mostly sedative and anxiolytic ones, most often used by women in the form of tea and usually indicated by some older family member. Conclusion: Psychosocial Care Center for Alcohol and Drugs users have knowledge about various medicinal plants and their uses. The most used plants are those with sedative / hypnotic and anxiolytic properties, which, in turn, have similar effects to the main drugs mentioned in the study. Consumption occurs without medical advice, constituting a risk to public health, mostly due to the lack of orientation and control of its use, as well as possible drug interactions.Objetivo: Avaliar o conhecimento sobre plantas medicinais e seus usos entre os pacientes do Centro de Atenção Psicossocial Álcool e Drogas do município de Palhoça. Métodos: Estudo Transversal, envolvendo 88 participantes, de ambos os sexos e diferentes idades que estiveram em atendimento no Centro de Atenção Psicossocial Álcool e Drogas entre fevereiro a junho de 2019, através da aplicação de um questionário e informações coletadas de seus prontuários. Dados analisados por estatística descritiva. Resultados: idade média de 42 anos, sexo masculino (64,8%), etnia branca (72,7%), uso abusivo de álcool (72,7%), cocaína (44,3%), maconha (35,2%) e 22,7% de crack (22,7%). Encontrou-se alta prevalência do uso de plantas medicinais (93,2%), principalmente as de caráter sedativo e ansiolíticas, usadas, na maioria das vezes, por mulheres, em forma de chá e geralmente indicadas por algum familiar mais velho. Conclusão: Os usuários do Centro de Atenção Psicossocial Álcool e Drogas apresentam conhecimento sobre várias plantas medicinais e seus usos. As plantas mais utilizadas são as com propriedades sedativas/hipnóticas e ansiolíticas, que, por sua vez, possuem efeitos semelhantes aos principais medicamentos citados no estudo. O consumo ocorre sem orientação médica, constituindo risco para a saúde pública, principalmente devido à falta de orientação e controle de seu uso, assim como as possíveis interações medicamentosas
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
