Desenvolvimento do português como língua segunda na perspetiva da Teoria dos Sistemas Dinâmicos: um estudo longitudinal com aprendentes chineses
Full text linkTese de doutoramento em Ciências da Linguagem (ramo do conhecimento em Linguística Aplicada)Baseado na Teoria dos Sistemas Dinâmicos (TSD), este estudo investiga a aprendizagem de português como língua não materna (PLNM) por aprendentes chineses, com foco no uso de preposições no complemento verbal e conetores coordenativos e subordinativos. O estudo analisou produções orais e escritas de 39 aprendentes chineses de PLNM, a residir na China continental, ao longo de oito momentos de recolha de dados durante um ano letivo. Este estudo investiga a dinâmica da aprendizagem de PLNM por aprendentes chineses, analisando dados de produção oral e escrita obtidos por meio de uma tarefa de narração oral e uma tarefa de redação escrita. Além disso, foi aplicado um teste inicial de LextPT para avaliar a proficiência em português dos participantes. O foco recai sobre o efeito dos momentos de recolha de dados (= fase) e sobre a influência da modalidade (oral vs. escrita) nas variações e padrões de erro. A análise estatística, conduzida por meio de Modelos Lineares Mistos Generalizados (GLMM), avaliou o impacto das fases em relação à fase inicial e à anterior, bem como a interação entre fase e modalidade de produção no uso das estruturas-alvo. A análise revelou que os conetores subordinativos na produção oral constituíram a única categoria com efeito de fase consistente em todas as comparações com a primeira fase, mostrando uma tendência de da taxa de erros progressiva ao longo do tempo. A pontuação no LextPT, indicativa da proficiência lexical e o número de orações apresentaram efeitos significativos em algumas estruturas específicas. As taxas de erro variaram conforme a estrutura e a fase, sendo os conetores coordenativos os que registaram menor incidência de erros, em contraste com as preposições no complemento verbal e os conetores subordinativos, nos quais predominaram os erros por omissão e troca inadequada. Quanto ao efeito da modalidade, as diferenças entre a produção oral e a escrita não se mantêm de forma uniforme, seja de modo global, seja ao longo das fases, nem se manifestam da mesma forma nas diferentes estruturas linguísticas.Based on the Dynamic Systems Theory (DST), this study examines the acquisition of Portuguese as a Foreign Language by Chinese learners, focusing on the use of verbal complement prepositions and coordinating and subordinating connectors. It analyzes oral and written productions from39 adults across eight phases over an academic year. Statistical analysis, using Generalized Linear Mixed Models (GLMM), assessed the impact of each phase compared to the initial and previous phases, as well as the interaction between phase and production modality on the use of these linguistic structures. This study explores the developmental dynamics of Portuguese as a Foreign Language (PFL) in Chinese learners, analyzing oral and written production data collected through a Narrative Task and a Composition Task. Additionally, an initial LextPT test was administered to assess participants’ proficiency in Portuguese. The focus is on the effect of data collection phases and the influence of modality (oral vs. written) on error patterns and variations. Statistical analysis, conducted through Generalized Linear Mixed Models (GLMM), evaluated the impact of each phase relative to the initial and preceding phases, as well as the interaction between phase and production modality in the use of these linguistic structures. The analysis revealed that subordinating connectors in oral production constituted the only category to exhibit a consistent phase effect across all comparisons with the first phase, indicating a progressive trend in error rates over time. Scores on the LextPT, which reflects lexical proficiency, and the number of clauses showed significant effects in certain specific structures. Error rates varied according to structure and phase, with coordinating connectors registering the lowest incidence of errors. In contrast, verbal complement prepositions and subordinating connectors showed higher rates of omission and inappropriate substitution errors. Regarding the effect of modality, the differences between oral and written production are not consistent, whether in overall terms, across developmental phases, or in how they manifest across different linguistic structures.Camões - Instituto da Cooperação e da Língu
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
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.
