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
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
Epistemological pluralism and cultural syncretism: a response to the controversies of theoretical ecology
No full textTradições acadêmicas no ensino da ecologia, assim como livros-texto convencionais redigidos de forma enciclopédica muitas vezes mascaram uma história de grandes controvérsias que existe por trás dos fundamentos teóricos desta disciplina. Muitos ecólogos são formados sem se darem conta dos diversos debates conflituosos que certamente circundam o corpo teórico de seus programas de pesquisa. Contudo, basta um aprofundamento mínimo na literatura para que se perceba a grande confusão que se transformou a formalização teórica da ecologia. Com suas raízes na história natural do século XIX e com uma ênfase empiricista, a ecologia passou por uma fase de formalização teórica calcada em uma episteme dedutivo-nomológica e na modelagem matemática de sistemas dinâmicos no começo do século XX. Este enfoque no aspecto conjectural da ecologia se consolidou na década de 1960 e muitos pesquisadores passaram a alegar que este seria o método ideal para a formalização de teorias sólidas e gerais. Entretanto, na década seguinte se inicia um contra-movimento, que criticou duramente esta escola alinhada ao pensamento dos físicos, culminando em debates que resultaram em posturas de radicalismo extremo em relação a qual é o objeto de estudo da ecologia e como o ecólogo deve proceder em sua atividade. Neste momento, passa a ser crucial que o cientista se volte à filosofia e à história das ciências para entender mais profundamente as origens e os motivos dessas confusões. Este conhecimento se faz necessário para que o ecólogo possa se posicionar criticamente dentro destas controvérsias e assim (re)definir seu próprio programa de pesquisa com mais coerência. Contudo, é preciso estar preparado para uma jornada psicologicamente intensa. Para muitos, esta empreitada histórico-filosófica gera um sentimento de frustração (no mínimo um grande desconforto intelectual) ao perceberem que a epistemologia não provê uma resposta simples e consensual para perguntas muito básicas como: o que é um conhecimento cientificamente válido? Quais são os fundamentos da teoria ecológica? A falta de treinamento em epistemologia associado à uma relutância psicológica em se envolver na área, mantiveram grande parte dos ecólogos afastada do debate filosófico, fazendo com que alguns equívocos sobre a ciência ecológica se propagassem por gerações. Assim, disputas intermináveis se sucederam na literatura dividindo os ecólogos ao invés de unir-los. Criou-se uma sensação geral de que há uma dicotomia entre teoria e empiria (também vista na forma de uma dicotomia conjectura-inferência), o que me parece um problema grave pois essa divisão é ilusória; a ciência é uma fusão desses dois componentes. Esta percepção dicotômica se estende a outros temas epistemológicos muito relevantes (\\textit{e.g.} indução ou dedução, descrição de padrões ou explicação por processos e mecanismos causais, generalidade ou precisão), o que a meu ver é prejudicial para um avanço fluente do conhecimento. Esta tese é uma tentativa de contextualizar historicamente o desenvolvimento do pensamento ecológico e revisar criticamente o debate epistemológico científico, assim como algumas controvérsias heurísticas relacionadas à modelagem de padrões e processos ecológicos, para então prover um argumento favorável ao pluralismo epistemológico na ecologia. Ao final, faço uma síntese das controvérsias epistemológicas, apresentando uma proposta de como conceber um programa de pesquisa em ecologia aberto ao pluralismo epistemológico. Para isso, valerei-me da noção de caixa preta epistemológica e de redes complexas de conhecimento tanto para mostrar que o pluralismo epistemológico pode ser visto como uma questão cultural intrínseca da ciência, como também para sugerir que uma postura colaborativa em detrimento de uma competitiva (conflituosa) é muito mais intuitiva e coerente para um ecólogo do século XXI. Acredito que uma predisposição ao sincretismo cultural em detrimento de um etnocentrismo “irracional” tem grande potencial de catalisar o avanço atravancado e controverso da ciência ecológicaAcademic traditions in teaching ecology, as well as conventional encyclopedical textbooks often mask a history of great controversies behind the theoretical bases of this discipline. Many ecologists are trained without realizing the many conflicting debates that surround the theoretical body of the research programs they are inserted in. However, a simple deepening in the literature is enough to sense the confusion that theoretical formalization of ecology has become. With its roots in 19th century natural sciences and with empiricist emphasis, ecology went through a phase of theoretical formalization based on a deductive-nomological epistemology and in mathematical modeling of dynamic systems in the beginning of 20th century. This focus on the conjectural aspect of ecology consolidated in the 60\'s and many researchers claimed this would be the ideal method to formalize solid and general theories. Yet in the following decade a counter-movement began, strongly criticizing this school of thought aligned with physicists, culminating in debates that resulted in extreme radicalism regarding the definition of ecology\'s study subject and how the ecologist should proceed in his activity. At this point it becomes crucial to the scientist to face philosophy and the history of sciences to further understand the origins and reasons for these confusions. This knowledge enables the ecologist to critically position oneself within these controversies and thus (re)define his own research program coherently. One should be prepared however, for an intense psychological journey. For many this historical-philosophical quest brings a sense of frustration (a great intellectual discomfort at least) since the epistemology does not provide a simple and consensual answer to basic questions such as: what is a valid scientific knowledge? What are the bases of ecological theory? This way, the lack of training in epistemology associated with psychological reluctance to get involved in this area, have kept most ecologists away from the philosophical debate, allowing some mistakes and misconceptions about the ecological sciences to propagate for generations. Thus, endless disputes in the literature divided ecologists instead of uniting them. A general sense was created that there is a dichotomy between theory and empiricism (also seen as a dichotomy between conjecture-inference), which seems to me as a serious problem given this division is illusory; science is the fusion of these two components. This dichotomous perception extends to other very important epistemological themes (e.g. induction or deduction, pattern description or explanation through causal processes and mechanisms, generality or precision), what hampers the advancement of ecological knowledge. This thesis is an attempt to contextualize historically the development of ecological thought and critically review the scientific epistemological debate, as well as some heuristic controversies related to modeling of ecological patterns and processes, to provide a favorable argument towards an epistemological pluralism in ecology. Finally, I synthesize the epistemological controversies, proposing how to conceive a research program in ecology opened to epistemological pluralism. For such I\'ll make use of the notion of an epistemological black box and of complex knowledge networks, both to show that epistemological pluralism can be seen as a cultural matter intrinsic to science, and also to suggest that a collaborative attitude instead of a competitive (conflicting) is much more intuitive and coherent with the 21st century ecologist. I believe that a predisposition to cultural syncretism in place of an “irrational” ethnocentrism has great potential to catalyze the advancement of the hampered and controversial science of ecolog
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.
