“…This is not entirely typical for biodiversity-related fields such as Botany and Ecology, as it is often informally suggested. They are respectively 11 th and 13 th out of 24 disciplines in terms of the ratio long-term to current (two-year based) impact factor (Contreras et al 2006). In addition to the need to attract highly original papers, a common strategy to achieve immediate citation is the publication of opinion papers and review papers (Scarano 2008).…”

-(A profile of the impact of Acta Botanica Brasilica: reflections on how to improve visibility and recognition of a scientific journal). We have estimated the ISI-impact factor of Acta Botanica Brasilica for the past six years, calculated the journal's h-index, calculated the journal's self-citation, examined country and institutions of origin of the papers that cite Acta papers, and examined scope and profile of the most-cited papers published by the journal. Results demonstrated a steep rise in impact factor and citation frequency in 2008, which is most encouraging, but also revealed that the journal is below the level of maturity expected of a 20-year old journal. Visibility of the journal is mostly national although, surprisingly, journal's self-citation of 12% is fairly low. We use Acta as an example to discuss possible strategies to enhance the international visibility of botanical journals that are newcomers to ISI.Key words: h-index, impact factor, scientometrics, self-citation RESUMO -(Um perfil do impacto da Acta Botanica Brasilica: reflexões acerca de como aumentar a visibilidade e o reconhecimento de um periódico científico). Este artigo estima o fator de impacto (ISI-Web of Science) do periódico Acta Botanica Brasilica para os últimos seis anos, calcula o índice-h do periódico, calcula a sua auto-citação, examina os países e instituições de origem dos artigos que citam artigos da Acta, e examina o escopo e o perfil dos artigos mais citados ao longo da história do periódico. Os resultados demonstraram um aumento substancial no fator de impacto estimado e na freqüência de citação em 2008, o que é muito encorajador, mas também revelaram que o periódico está abaixo do grau de maturidade esperado para um periódico com 20 anos de existência. A visibilidade do periódico é predominantemente nacional embora, surpreendentemente, a auto-citação de 12% seja consideravelmente baixa. A revista é utilizada como exemplo para discutir possíveis estratégias para aumentar a visibilidade internacional de periódicos em botânica recém-indexados no ISI.Palavras-chave: auto-citação, cientometria, fator de impacto, índice h

“…Previously, Park (2015) used logistic regression and empirical analysis to verify whether a national technology innovation R&D program's performance followed the stepwise chain structure of typical R&D logic models. Contreras et al (2006) estimated the long-term impact of journals aggregated in 24 different fields using a simple logistic diffusion model, relating their results to the current impact factor. Recently, Li et al (2017) investigated the degree of personal citation in Chemistry, Mathematics, and Physics, as well as the factors influencing it, such as total citations, h-index, and citations per publication, applying binary logistic regression.…”

In order to estimate the impact factor value for a journal in Dentistry, two sets of variables were considered in this study: the first takes in the longitudinal behavior of the process specified in the slope and intercept of the straight line fitted to the trend of the last years, whereas the second considers the percentage of review papers published each year and the adhesion degree of the journal to ICMJE guidelines. The final estimated model showed a high determination coefficient (99.3%) and its performance was tested on a new set of journals randomly sampled from the list of journal citation reports.

“…This dependence appeared to possibly change over the years. C ontreras , E dwards and W izala (2006) estimate a logistic diffusion model per discipline for the number of citations. Their approach allows estimating a so‐called current impact factor (CIF) as well as a long‐term impact factor, which represents the value to which the cumulative impact would converge (M).…”

In this paper, we answer the question why statistics journals get lower impact factors than journals in other disciplines. We analyze diffusion patterns of papers in several journals in various academic fields. To obtain insights into the diffusion of the citation counts of the papers, the data are analysed with the Bass model, leading to values for the time-to-peak that can be used to compare the speeds of diffusion paper citations of the different disciplines. Estimation results show that for statistics journals, it takes significantly more years to reach their peak. To further investigate diffusion, we also compute the percentages of the total number of citations a paper has after 2 or 3 years.Again, it appears that statistics journals have slower citation diffusion than journals in other disciplines. We conclude with some suggestions to reduce this disparity.
