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
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
Behavior, activity and social interaction between queens and workers of Metapolybia docilis (Vespidae: Polistinae: Epiponini).
No full textAs sociedades de vespas da tribo Epiponini caracterizam-se pela variação no número de rainhas durante o ciclo colonial, o que implica na ocorrência cíclica de muitas rainhas (poliginia), poucas (oligoginia) e até uma rainha (monoginia). Durante as primeiras fases do ciclo colonial existe um número maior de rainhas, mas conforme a colônia cresce, o número de rainhas diminui. Os Epiponini também são caracterizados pela complexidade morfológica e as síndromes de diferenciação de castas. Entretanto, para algumas espécies dentro dos Polistinae, a única forma de separar as fêmeas reprodutoras das não reprodutoras é pelo comportamento ou pelo grau de desenvolvimento dos ovários. O estudo do comportamento e as interações sociais junto com os estudos morfométricos podem ajudar no entendimento da evolução da complexidade encontrada dentro dos Epiponini. Por isso o objetivo deste trabalho é descrever o comportamento das rainhas e operárias em Metapolybia docilis, e suas interações. Foram realizadas observações individuais do comportamento das rainhas e operárias previamente marcadas de quatro colônias de M. docilis. Foi feito um catálogo dos atos comportamentais observados com maior frequência. Para as rainhas os comportamentos incluíam tanto displays como comportamentos relacionados às necessidades básicas como alimentação e higiene, nas operárias os comportamentos incluíam principalmente trabalhos de manutenção do ninho e policiamento. Para realizar as análises morfométricas todos os indivíduos das colônias C1, C2 e C3 foram coletados, foi determinada a idade dos indivíduos da colônia e oito medidas corporais externas foram tomadas de uma amostra de 50 operárias e de todas as rainhas das colônias. A colônia C1 estava em Fase Matura, a colônia C2 em Fase de Pré- Enxameagem, as colônias C3 e C4 em Fase de Estabelecimento. Os comportamentos realizados com maior frequência pelas rainhas das quatro colônias foram: curvar o abdômen (CA), dança de display (DD), inspeção de célula (IC), trofalaxia (Tx) e auto-limpeza (Limp). Os comportamentos realizados com maior frequência pelas operárias foram IC e Tx. O comportamento CA provavelmente é um comportamento display de dominância feito pelas rainhas e o comportamento DD provavelmente está ligado a interações competitivas ou de dominância entre as fêmeas das colônias. Não foi encontrada diferenciação morfológica significativa entre rainhas e operárias de M. docilis para as colônias C2 e C3, mas sim para a colônia C1. Dentro das colônias estudadas o controle na reprodução das fêmeas é feito mediante o comportamento e não por manipulação larval. As operárias e as rainhas testam a capacidade reprodutiva das outras rainhas mediante displays de dominância não agressivos para decidir que fêmeas continuaram encarregando-se de produzir novos indivíduos. As operárias possivelmente controlam a reprodução (mediante o policiamento de ovos), seleção das rainhas, e todos os outros aspectos dentro da colônia explorando o ambiente e as necessidades do ninho.Epiponini wasps societies are characterized by the alternation in the number of queens from many (polygyny) to few queens (olygyny) or even one (monogyny) during the colony cycle. When the colony is in the growing phase there are many queens, but as colony grows queen number decreases and new queens will be produced only when queen number is close to one (monygyny). Epiponines wasps are also characterized by the complexity of the morphological caste syndromes. However, in some Epiponini species the only way to separate reproductives from not reproductives is by behavioral acts or by the degree of ovarian development. The study of behavior and social interactions, associated with morphometric studies, could help to better understand the evolution and complexity found within the Epiponini. We studied and described behavioral acts and interactions between queens and workers in Metapolybia docilis. We performed direct and indirect (video) observations of individual behavior of previously marked queens and workers from four M. docilis colonies. We catalogued the most frequently observed behavioral acts: for queens these behaviors included displays and basic need behaviors such as feeding and hygiene; for workers they included nest maintenance and policing behaviors. All the individuals from colonies C1, C2 and C3 were collected to perform a morphometric analysis and age determination by taking eight external body measurements from a 50 workers sample and from all the queens of the colonies. Colony C1 was in an Emergence phase, colony C2 in a pre-swarming phase, colonies C3 and C4 in a pre-emergence phase. Most frequently behaviors made by queens were bending abdomen (BA), dance display (DD), cell inspection (CI), trofalaxis (Tx) and grooming (G). Most frequently behaviors made by workers were IC and Tx. Bending abdomen (BA) is probably a dominance display made by queens, and dance display (DD) was probably a test behavior made by workers and queens to test another queens. For colonies C2 and C3 there is no morphological differences between queens and workers, but there is a slight difference for colony C1. Within the colonies, the reproduction control is performed by behavior and not by larval manipulation because we did not found morphological differences between castes. Workers and queens tested the reproductive capacity of the queens by non aggressive dominance displays in order to select which females perform the reproduction work in the colony. Workers probably control the reproduction (by worker policing on the eggs laid), queen selection and all the others tasks on the colony by scanning the environment and the needs of the colony
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.
