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
Enhancing the Multi-Objective Recommendation from three new perspectives: data characterization, risk-sensitiveness, and prioritization of the objectives
Full text linkRecommender Systems are tools whose main objective is to help users find relevant items among many options. However, different "relevance" concepts can be defined, making the recommendation task even more challenging if we want good recommendations on multiple quality concepts, e.g., accuracy, novelty, and diversity. In this scenario, the recommendation needs to use multi-objective optimization mechanisms. Although we find works focused on this type of recommendation, most of them are limited in some relevant aspects. In particular, three aspects provide scope for improving the multi-objective recommendation on new perspectives with the use of additional resources: (a) meta-features: implicit characteristics of input data can influence algorithms, e.g., quantity and distribution of items' ratings, therefore, explicit use of statistical measures capable of measuring some of those characteristics can be helpful in the multi-objective recommendation; (b) risk sensitivity: the optimization by global averages of multiple criteria can generate bad results in exchange for some excellent results that, although rare, can positively affect these averages, therefore, explicit use of risk sensitivity metrics can be helpful in the optimization process, reducing harmful recommendations without degrading global averages; (c) prioritization of objectives: users have different preferences regarding the quality criteria of recommendations, e.g., while some users do not give up favorite items, others may be more tolerant of discovering new items or a greater diversification of items, therefore, explicit use of users' preferences regarding the quality criteria can also be helpful to improve multi-objective recommendations further. Accordingly, in this work, we investigated the multi-objective recommendation from these three new perspectives and defined specific recommendation methods. Extensive experiments validated these methods, answered our research questions positively, and improved our knowledge concerning multi-objective recommendations on these three aspects, opening opportunities for relevant future work.Sistemas de Recomendação são ferramentas cujo principal objetivo é auxiliar os usuários a encontrar itens relevantes em meio a muitas opções. Entretanto, diferentes conceitos de "relevância" podem ser definidos, tornando a tarefa de recomendação ainda mais desafiadora se desejarmos boas recomendações sobre múltiplos conceitos de qualidade, e.g., acurácia, novidade e diversidade. Neste cenário, a recomendação precisa utilizar mecanismos de otimização multi-objetivo. Apesar de encontrarmos trabalhos voltados para a este tipo de recomendação, a maioria deles possui limitações sobre alguns aspectos relevantes. Três aspectos, em especial, abrem margem para aprimorar a recomendação multi-objetivo sobre novas perspectivas com o uso de recursos adicionais: (a) meta-features: características implícitas dos dados de entrada podem influenciar os algoritmos, e.g., quantidade e distribuição dos ratings dos itens, portanto, o uso explícito de medidas estatísticas capazes de mensurar algumas destas características pode ser útil no processo de recomendação multi-objetivo; (b) sensibilidade ao risco: a otimização de múltiplos critérios pelas suas médias globais pode gerar resultados ruins em favorecimento de alguns resultados muito bons que, embora raros, sejam capazes de afetar positivamente as médias, portanto, a utilização explícita de métricas de sensibilidade ao risco pode ser útil no processo de otimização, reduzindo as recomendações ruins sem degradar as médias globais; (c) priorização dos objetivos: usuários possuem diferentes preferências em relação aos critérios de qualidade das recomendações, e.g., enquanto alguns usuários não abrem mão de itens prediletos, outros podem ser mais tolerantes à descoberta de novos itens ou maior diversidade de itens, portanto, a utilização explícita de preferências dos usuários sobre os critérios de qualidade também pode ser útil para melhorar ainda mais as recomendações multi-objetivo. Sendo assim, neste trabalho investigamos a recomendação multi-objetivo sobre a ótica destas três novas perspectivas e definimos métodos de recomendação específicos. Extensos experimentos validaram esses métodos e respondem positivamente às nossas questões de pesquisa, e também nos permitiram começar a entender melhor a recomendação multiobjetivo sobre esses três aspectos, abrindo margem para relevantes trabalhos futuros
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn 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.
