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
INFLUÊNCIA DAS OFERTAS PÚBLICAS DE AÇÕES NOS NÍVEIS DE GERENCIAMENTO DE RESULTADOS E SEU IMPACTO NO RETORNO DAS AÇÕES
No full textEste estudo tem por objetivo analisar a influência da oferta pública de ações nos níveis de gerenciamento de resultados e seu impacto no retorno de mercado das ações das companhias brasileiras. Para tal análise, calculam-se os accruals discricionários, utilizando o modelo Kang e Silvaramakrishnan (1995), e apuram-se as médias dos accruals nos períodos pré e pós-ofertas pública de ações. Para o desempenho de mercado é utilizado o preço da ação nos trimestres anteriores e posteriores às ofertas públicas secundárias, sendo que todos os dados necessários para tal análise são extraídos da base de dados Economatica®. A pesquisa envolve 30 companhias listadas na BM&FBovespa S.A., que realizaram ofertas públicas de ações no período de 2011 e 2012. Os resultados dos modelos de regressões indicam que não há relação estatisticamente significativa entre o gerenciamento de resultados, as ofertas públicas de ações e o retorno médio dos preços das ações. Conclui-se, assim, que não existe influência do gerenciamento de resultados nos retornos das ações após a realização de ofertas públicas de ações
Contenção da dissociação em hospital particular por meio da gestão orçamentária: Containment of dissociation in a private hospital through budget management
Full text linkBudgeting, conceptualized as an effective instrument in resource management with significant influence on control and decision-making, is an essential tool in the process of business planning and control. Thus, this research aimed to identify if this artifact can serve as a means for controlling dissociation in a private hospital, analyzing the perspectives of those involved regarding its use. For this purpose, a semi-structured interview was conducted to collect data, characterized by a descriptive nature with a qualitative approach through a case study. As a result, it was found that there is disagreement between doctors and administrators, as while the former requests resources, the latter seeks to maintain business performance within imposed limits. In light of this, it can be concluded that this artifact can assist in the containment of dissociation in the hospital environment, as it allows for resource management in a way that administrators understand how to meet medical demands.Conceituado como um instrumento eficaz na gestão de recursos, com significativa influência no controle e tomada de decisão, o orçamento é uma ferramenta essencial no processo de planejamento e controle empresarial. Assim, esta pesquisa teve como objetivo identificar se esse artefato pode convir como meio de controle da dissociação em hospital privado, analisando, para isso, a visão dos envolvidos em relação ao seu uso. Isto posto, utilizou-se entrevista semiestruturada para a coleta de dados, sendo caracterizada pela natureza descritiva com abordagem qualitativa, por meio de estudo de caso. Como resultado, constatou-se que há dissentimento entre médicos e administradores, pois, enquanto o primeiro requisita recursos, o outro procura manter o desempenho empresarial em concordância com os limites impostos. À vista disso, conclui-se que esse artefato pode auxiliar na contenção da dissociação no ambiente hospitalar, pois permite a gestão dos recursos de modo que os administradores compreendam como atender às demandas médicas
Gestor da cooperativa e influência do seu comportamento estratégico na participação orçamentária, assimetria informacional e folga orçamentária
No full textThe research analyzed the influence of the strategic behavior of credit union managers, with budgetary participation, information asymmetry and budgetary slack. To achieve the proposed objectives and test the hypotheses, the research was characterized as descriptive, survey and quantitative, with data from sixty-one (61) managers of credit unions in the state of Paraná. Respondents were classified according to their strategic typology based on the studies by Miles and Snow (1978) and Conant, Mokwa and Varadarajan (1990), using the Multivariate Analysis of Variance (MANOVA) statistical tool as an analysis procedure. The results suggest a significant mean difference between defender behavior and other behaviors with regard to budgetary participation, a negative and significant mean difference between strategic analytical behavior and prospector and reactive behavior with regard to Informational asymmetry, no signs of significant differences between the strategic behaviors in relation to the budgetary slack variable were found. Knowing how managers react to each strategic behavior in the business budget can facilitate its allocation in areas of greater or lesser autonomy, budget or market niche, enabling greater assertiveness to the proposed objectives.A pesquisa analisou a influência do comportamento estratégico dos gestores da cooperativa, com participação orçamentária, assimetria da informação e folga orçamentária. A pesquisa foi caracterizada como descritiva, do tipo survey e quantitativa, com dados de sessenta e um (61) gestores de cooperativas de crédito do estado do Paraná. Os respondentes foram classificados conforme sua tipologia estratégica com base nos estudos de Miles e Snow (1978) e Conant, Mokwa e Varadarajan (1990), utilizando-se como procedimento de análise a aplicação da ferramenta estatística Análise Multivariada da Variância (MANOVA). Os resultados sugerem diferença de média significativa entre o comportamento defensor e os demais comportamentos no que tange a participação orçamentária, uma diferença de média negativa e significativa entre o comportamento estratégico analítico e o comportamento prospector e reativo no que tange a assimetria informacional, não foram encontrados indícios de diferenças significativas entre os comportamentos estratégicos em relação a variável de folga orçamentária. O conhecimento de como reage os gestores de cada comportamento estratégico no orçamento empresarial pode facilitar a alocação deste em áreas de maior ou menor autonomia, orçamento ou nicho de mercado, possibilitando maior assertividade aos objetivos propostos
