Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Dietoterapia como estratégia adjuvante ao tratamento dos sintomas de depressão : uma revisão sistemática
Introdução: De acordo com recentes publicações científicas internacionais, uma grande parcela da população mundial sofre de sintomas depressivos e este número vem aumentando progressivamente. Paralelo a isso, descobertas recentes revelam o potencial efeito terapêutico de dietas no tratamento dos sintomas. No entanto, por grande parte dos estudos possuírem caráter observacional, emerge a necessidade de analisar ensaios clínicos randomizados com humanos que avaliam o efeito de intervenções nutricionais nos sintomas depressivos. Objetivo: Realizar uma revisão sistemática sobre o efeito terapêutico de estratégias nutricionais nos sintomas de depressão em seres humanos. Métodos: Foi realizada busca no PubMed associando descritores sinônimos de depressão e padrão alimentar. Dos 486 artigos resultantes da busca, 12 atenderam aos critérios de elegibilidade: ECRs que avaliaram a melhora dos sintomas depressivos em adultos (≥ 18 anos) por meio de intervenções nutricionais. Resultados: Seis estudos observaram melhora nos sintomas depressivos em relação ao grupo de comparação e as principais intervenções nutricionais com desfechos significativos foram padrões alimentares baseados em uma dieta rica em triptofano, de baixa carga glicêmica, mediterrâneo, LowFODMAP, rica em polifenóis e DASH. Estes estudos utilizaram as escalas SDS, CES-D, CGI-I, HADS, POMS, DASS-21 e BDI-II de sintomas depressivos. Conclusão: Seis intervenções nutricionais utilizadas nos estudos selecionados foram eficazes para melhorar os sintomas depressivos. Isso evidencia que os padrões alimentares devem ser considerados como estratégias terapêuticas adjuvantes ao tratamento da depressão.Introduction: According to recent international scientific publications, a large portion of the world's population suffers from depressive symptoms and this number is progressively increasing. Also, recent discoveries reveal the potential therapeutic effect of diets in the treatment of symptoms. However, since most of the studies are observational, there is a need to analyze randomized clinical trials (RCTs) with patients to evaluate the effect of nutritional interventions on depressive symptoms. Objective: To carry out a systematic review based on the therapeutic effect of nutritional strategies on depression symptoms in patients. Methods: A search was performed on PubMed associating synonymous descriptors of depression and dietary patterns. Of the 486 articles resulting from this primary search, 12 met the eligibility criteria: RCTs that evaluated the improvement of depressive symptoms in adults (≥ 18 years) through nutritional interventions. Results: Six studies observed improvement in depressive symptoms compared to the baseline and control group, and the main nutritional interventions with significant improvements in the symptoms were dietary patterns based on a tryptophan-rich, low-glycemic-load, Mediterranean, LowFODMAP, polyphenol-rich, and DASH diet. These studies used the SDS, CES-D, CGI-I, HADS, POMS, DASS-21 and BDI-II scales of depressive symptoms. Conclusion: Most of the nutritional interventions used in the selected studies were effective in improving depressive symptoms. This shows that dietary patterns should be considered as adjuvant therapeutic strategies in the treatment of depression
Variations on the Author
“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
We 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
We 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
We 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
In 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.
