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
Speeches and production of meanings: experience in policy transfer of directly observed treatment short-course to control tuberculosis in Mozambique - Africa
No full textA estratégia do Tratamento Diretamente Observado de Curta Duração para o controle da tuberculose (DOTS) tem sido usada por vários países do mundo especificamente pelos 22 mais afetados pela doença, que contribuem com cerca de 80% de casos, porém, apesar da estratégia demonstrar a redução de casos e aumentar a adesão dos pacientes ao tratamento, e ter sido implementada em Moçambique desde a década de 1980, a doença continua a ser um problema grave de saúde pública no país. Este estudo tem como objetivo central: analisar a transferência da política do DOTS a partir da visão dos gestores centrais, provinciais e distritais, e profissionais de saúde da província de Nampula. Trata-se de um estudo qualitativo que usa a Análise de Discurso de matriz francesa como seu referencial teórico metodológico que busca a compreensão dos sentidos a partir das condições da produção. Participaram deste estudo 15 profissionais de saúde que ocupavam as posições de gestores, médicos e profissionais de enfermagem e/ou técnicos, e atuavam no Programa nacional de controle de Tuberculose em Moçambique com o mínimo de um ano de experiência, nos meses de maio a agosto de 2014, nos níveis central, provincial (Nampula), e distrital (em oito distritos da província de Nampula). Para a coleta de dados usou-se um roteiro de entrevista semi-estruturado que permitiu explorar os sentidos produzidos. O corpus em análise foi constituído a partir das entrevistas transcritas. Para o auxílio da organização dos dados usou-se o sofware Atlis.ti versão 6. Este estudo teve a aprovação da Comissão Nacional de Bioética e da autorização do Ministro da Saúde de Moçambique. Para a análise dos dados foram identificados quatro blocos discursivos: experiências adotadas na implementação e manutenção do DOTS; estratégias adotadas na implementação e manutenção de DOTS; potencialidades, fragilidades de DOTS no controle da tuberculose e; discursos não buscados pelo roteiro: possíveis soluções. Os sentidos produzidos enfatizam dizeres inscritos em formações discursivas que desconsideram a subjetividade do enfermo; de fragilidades do sistema de saúde, falta de recursos humanos, falta de transporte, baixos salários, insuficiência de laboratórios, distâncias longas entre a moradia do paciente e a unidade sanitária. Ainda os entrevistados entendem como potencialidade a participação dos agentes comunitários e da família no tratamento da doença. Conclui-se que para o controle da tuberculose usando a estratégia DOTS o compromisso do governo deve ser pragmático traduzindo-se em ações concretas como o aumento do financiamento das ações de controle de tuberculose, incluindo as pesquisas, formação dos recursos humanos e, sobretudo, atuar sobre os determinantes socias da saúdeThe Directly Observed Treatment Short-Course (DOTS) strategy has been used in many countries, mainly in the 22 most affected by tuberculosis, which contributes about 80% of cases. However, despites the strategy shows the decline of cases and the increase of adherence to treatment, and it has been implemented in Mozambique since 1980\'s decade, the disease remains as a serious public health problem. This study aimed to: analyzing the policy transfer of DOTS strategy from the point of view of central, provincial and district managers, and health professionals from the province of Nampula. It is a qualitative study, which uses the Discourse Analysis of french matrix as theoretical and methodological framework, which seeks to understand the meanings from the production conditions. Fifteen health professionals that occupied managers, physician, nurses and/or technicians positions during, at least, one year of experience in the National Program of Tuberculosis Control in Mozambique, between may to august, 2014, in the central, provincial (Nampula) and district (in 8 districts at the province of Nampula), participated. For data collection, it was used a semi-structures interview\'s script, that allowed to explore the produced meanings. The corpus under analysis was produced from transcript inteviews. To support the data organization, it was used the software Atlas.Ti, version 6. This study had the approval of the National Committee of Bioethics and the authorization of the Ministry of Health of Mozambique. In the analysis, it was identified four discursive blocks: adopted experiences in implementation and maintenance of DOTS; strengths, weaknesses of DOTS in tuberculosis control and; unfetched speech by the script: possible solutions. The produced meanings emphasizes sayings written in discursive formations that disregard the subjectivity of ill; the weaknesses of health system, the lack of human resources and transportation, low wages, the insufficient number of laboratories, long distances between the patient housing and the health unity. Respondents still understood as strengths the involvement of community workers and family on treatment. It is concluded that for tuberculosis control using DOTS strategy, government commitment is pragmatic, translating up in concrete actions with the increase of financing for tuberculosis control, including research, training of human resources and, above all, act on the social determinants of healt
Experiências e percepções sobre a gravidez na adolescência: um estudo fenomenológico
No full textA gravidez na adolescência e um problema de saúde pública para todo o mundo e principalmente para os países em vias de desenvolvimento. Este trabalho tem como objectivos: compreender as experiencias e as percepções sobre a gravidez na adolescência sobretudo as relacionadas com a decisão de levar a gravidez ao termo e os problemas sócio-económicos e de saúde vivenciados pelas adolescentes ao longo da gravidez; descrever as experiencias e percepções sobre a gravidez na adolescência sob perspectiva das jovens envolvidas no estudo; avaliar os factores favorecedores e as barreiras na decisão de levar a gravidez ao termo, incluindo as influencias do agregado familiar e do parceiro; avalias as dificuldades vividas durante a gravidez na adolescência, com relação aos aspectos sócio-económicos e de saúde. Este estudo usou o método qualitativo baseado na perspectiva fenomenológica proposto por Giorgi para melhor compreender as experiencias e percepções da população em estudo. Participara na entrevista 25 mães adolescentes com idade ≤ a 19 anos que tiveram gravidez de termo e que a criança estava a ser acompanhada nas consultas de peso no Hospital Geral de Chamaculo e aceitou participar no estudo voluntariamente após o convite. As informações dessas mães foram suficientes para se atingir a chamada saturação teórica que consiste na suspensão de inclusão de novos participantes quando os dados obtidos passam a apresentar na avaliação do pesquisador, uma certa redundância ou repetição não sendo relevante persistir na colecta de dados. Os achados deste estudo mostram que o fenómeno da gravidez na adolescência não pode ser isolado do seu contexto sobretudo da família, redes da sociabilidade da adolescente e aspectos sócio-económicos. A gravidez na adolescência cria situações complexas para a adolescente e que podem ter efeitos negativos para o seu futuro.2021-08-22Teenage pregnancy is a public health problem for the whole world and especially for developing countries. This work aims to: understand the experiences and perceptions about teenage pregnancy, especially those related to the decision to carry the pregnancy to term and the socioeconomic and health problems experienced by the adolescents throughout the pregnancy; describe the experiences and perceptions about teenage pregnancy from the perspective of the young women involved in the study; to evaluate the factors favoring and the barriers in the decision to take the pregnancy to term, including the influences of the household and the partner; assesses the difficulties experienced during pregnancy in adolescence, in relation to socioeconomic and health aspects. This study used the qualitative method based on the phenomenological perspective proposed by Giorgi to better understand the experiences and perceptions of the study population. 25 adolescent mothers aged ≤ 19 years who had a full-term pregnancy and that the child was being followed up in weight consultations at the Hospital Geral de Chamaculo had participated in the interview and accepted to participate in the study voluntarily after the invitation. The information from these mothers was sufficient to achieve the so-called theoretical saturation, which consists in suspending the inclusion of new participants when the data obtained starts to show, in the researcher's assessment, a certain redundancy or repetition, and it is not relevant to persist in the data collection. The findings of this study show that the phenomenon of teenage pregnancy cannot be isolated from its context, especially from the family, networks of adolescent sociability and socio-economic aspects. Teenage pregnancy creates complex situations for the teenager that can have negative effects on her future. (TRADUÇÃO NOSSA
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
