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
Design de gamificação em aprendizagem colaborativa com suporte computacional: utilizando uma abordagem para a adaptação de princípios de influência a papéis de jogadores
No full textGamification is a term that refers to the use of game design elements in contexts other than video games. In these contexts, the primary goal of gamification is not playful, but rather to motivate users to perform tasks or change behaviors. It is also the goal of gamification, captivate users and influence them to persist in the use of the gamified system. In recent years, we have witnessed a growing interest in gamification and its application in learning environments, especially online. In learning contexts, motivating students to follow up on teaching tasks is an important role for teachers and intelligent educational systems. However, ill-designed gamification interventions can become a distraction capable of interfering on the teaching-learning process. Despite this, most studies in the area remain focused on the potential benefits of gamification and less on investigating systematized solutions to achieve these benefits. Our contribution to the solution of the problem is based on the use of persuasion profiles that take into account the students player roles. We conduct systematic mappings of the literature to gather information about gamification in education, and how group formation in collaborative learning environments. As a result, we created two conceptual frameworks. One framework to help understand and classify group formation in the context of computer-supported collaborative learning, and other to support the definition of player roles in collaborative learning environments. Also, in a preliminary study (N = 481), we adapted and validated for Brazilian Portuguese speakers a scale to measure users susceptibility to persuasion. In another study (N = 149) we developed a theoretical model to map persuasive strategies and different roles of players to support the elaboration of persuasion profiles. Finally, to verify the feasibility of our model, in another study (N = 18) we elaborated prototypes of user interfaces and analyzed the perceived persuasiveness of the interfaces for different players roles and their susceptibility to persuasion. Results show that less motivated students were more likely to accept the suggestions of the prototypes, whereas users with above-average motivation (among observed students) reacted negatively to influence attempts by showing low agreement rates for the requirements of the prototypes. We also observed in the three studies (N = 648) that the number of individuals susceptible to the principle of authority were the lowest, compared to the other influence principles. Few research initiatives have been investigating the development of tailored gamified. One of the reasons for such deficiency is the difficulty of creating computational models based on learners psychological traits (e.g., psychological needs, susceptibility to persuasion, and learner and player roles). However, more worrisome than the ineffectiveness of gamification models based on one-size-fits-all is the risk of designing counterproductive models that could backfire, since the appropriate strategy to motivate an individual may end up discouraging others. Thus, evidence suggest that gamification design could benefit of influence principles, although tailored solutions should be designed to minimize the risks of selecting counter-tailored and ill-defined persuasive strategies.Gamificação é um termo que se refere ao uso de elementos do projeto de jogos em contextos que não são jogos. Nestes contextos, o objetivo primário da gamificação não é lúdico, mas sim o de motivar os usuários a realizarem tarefas ou alterarem comportamentos. Também é objetivo da gamificação, cativar usuários e influenciá-los a persistirem na utilização do sistema gamificado. Nos últimos anos, testemunhamos um crescente interesse em gamificação e sua aplicação em ambientes de aprendizagem, especialmente online. No contexto da aprendizagem, motivar os estudantes a dar seguimento as tarefas pedagógicas é um papel importante dos professores e dos ambientes educacionais inteligentes. Por essa razão, as tecnologias persuasivas como a gamificação têm sido usadas também em ambientes de aprendizagem colaborativa para aumentar o engajamento dos estudantes e para reduzir o sentimento de obrigação na execução de tarefas pedagógicas. Contudo, quando mal utilizada, a gamificação pode se tornar uma distração capaz de interferir no processo de ensino-aprendizagem. Entretanto, a maioria dos estudos na área continuam focados nos potenciais benefícios da gamificação e menos em investigar soluções sistematizadas para se atingir os benefícios. Nossa contribuição para a solução do problema é baseada no uso de perfis de persuasão que levam em consideração o papel de jogador do estudante. Nós conduzimos mapeamentos sistemáticos da literatura para obter informação sobre gamificação em educação e como são formados grupos de estudantes em ambientes de aprendizagem colaborativa. Como resultado nós criamos dois arcabouços conceituais. Um arcabouço para ajudar a compreender e classificar a formação de grupos no contexto da aprendizagem colaborativa com suporte computacional, e outro para apoiar a definição de papéis de jogadores em ambientes colaborativos. Em um estudo preliminar (N=481), adaptamos e validamos para o português brasileiro uma escala para medir a susceptibilidade à persuasão dos usuários. Em outro estudo (N=149) desenvolvemos um modelo teórico para mapear estratégias persuasivas e diferentes papéis de jogadores para apoiar a elaboração de perfis de persuasão. Para verificar a viabilidade de nosso modelo, em outro estudo (N=18) elaboramos protótipos de interfaces do usuário. Analisamos a capacidade de influenciar das interfaces comparando papéis de jogadores e susceptibilidade a princípios de influência. Os resultados mostram que os estudantes menos motivados eram mais susceptíveis a aceitar as sugestões do protótipo, enquanto usuários com índices de motivação acima da média (dentre estudantes observados), tendiam a reagir negativamente às tentativas de influenciá-los, apresentando índices menores de concordância para com as solicitações do protótipo gamificado. Observamos ainda nos três estudos conduzidos (N=648), comparado aos outros princípios de influência, o número de indivíduos suscetíveis ao princípio de autoridade eram os menores. Poucas iniciativas de pesquisa vêm investigando como desenvolver sistemas de gamificados que se adaptam aos papéis de jogadores. Parte desta deficiência pode ser explicada devido à complexidade no projeto e desenvolvimento destes sistemas. Entretanto como evidenciado, além da ineficácia dos modelos de gamificação baseados em uma solução para todos, o maior risco observado está no uso de modelos contraproducentes, uma vez que a estratégia apropriada para motivar um indivíduo, pode acabar desmotivando outros (backfire effect)
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
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.
