Um estudo dos direcionadores da distribuição de dividendos das empresas não financeiras participantes da B3
Get PDFThe purpose of this study was to identify the dividend policy drivers of Brazilian companies
listed on B3 through the Dividend Yield and Dividend Payout indicators, also considering these
relationships given the division of B3's sectors. Among the theoretical approaches of the study,
the theory of relevance of dividends, the theory of the irrelevance of dividends, asymmetric
information, agency theory, the hypothesis of the life cycles of organizations, the theory of
fiscal and tributary effects, clientele and specific aspects of Brazilian legislation, in which there
is more than one form of distribution of earnings. Through a theoretical review that included
several authors and studies for different markets, including within Brazil, variables such as size,
indebtedness, shareholding concentration, corporate governance, profitability, liquidity, among
others, were mapped as possible drivers of dividend policy. The sample used included 537
companies with annual data between 1996 and 2020. The initial analysis of the study points out
that the Public Utility and Communications sectors are the sectors that most distribute earnings,
while the Others sector can be characterized as the worst distributor. To estimate the dividend
policy drivers, a panel data model and the econometric method of Quantile Regression with
quantiles .25, .5, .75 and .9 were used as estimation parameters. For the estimations with the
entire sample, without sector division, the results indicate that: i) the asset size is significant,
positive and increasing for all quantiles of both variables; ii) earnings per share are positive and
significant for all DY quantiles; iii) GDP, exchange rate and CDI are significant to explain
companies' dividend policy; iv) belonging to differentiated levels of corporate governance
positively impact companies that distribute less dividends and negatively impact companies
that distribute more dividends; and v) variables related to profitability and indebtedness did not
perform well to explain the companies' dividend policy. When we look at each sector of activity,
the results show that: i) in general, the size of the asset is positive, increasing and significant
for most quantiles considering both dependent variables; ii) GDP, CDI and Exchange rate show
good performance to explain companies' dividend policy; iii) the control characteristics related
to indebtedness, liquidity, risk and profitability present different relationships for each sector;
iv) characteristics related to shareholding control and belonging to differentiated segments of
corporate governance indicate the presence of a clientele and signalling effect in the dividend
policy of companies, depending on the sector in which they operate.O propósito do presente estudo foi identificar os direcionadores da política de dividendos das
empresas brasileiras listadas na B3 através dos indicadores Dividend Yield e Dividend Payout,
considerando também essas relações dada a divisão de setores da B3. Levou-se em conta como
abordagem teórica as teorias da relevância dos dividendos, da irrelevância dos dividendos,
informação assimétrica, agência, hipótese do ciclo de vida, efeitos fiscais e tributários, efeito
clientela e os aspectos específicos da legislação brasileira. Através de uma revisão teórica que
abarcou diversos autores e estudos para diferentes mercados, variáveis como tamanho,
endividamento, concentração acionária, governança corporativa, rentabilidade, liquidez, entre
outras, foram mapeadas como possíveis direcionadores da política de dividendos. A amostra
utilizada contou com 537 empresas com dados anuais entre 1996 e 2020. A análise inicial do
estudo aponta que os setores de Utilidade Pública e Comunicações são os que mais distribuem
proventos, enquanto o setor Outros pode ser caracterizado como o pior distribuidor. Para
estimar os direcionadores da política de dividendos, foi utilizado um modelo com dados em
painel e o método econométrico da Regressão Quantílica com os quantis .25, .5, .75 e .9
utilizados como parâmetros de estimação. Para as estimações com toda a amostra, sem divisão
de setor, os resultados apontam que: i) o tamanho do ativo é significativo, positivo e crescente
para todos os quantis de ambas as variáveis; ii) o lucro por ação é positivo e significativo para
todos os quantis de Dividend Yield; iii) PIB, câmbio e CDI são significativas para explicar a
política de dividendos das empresas; iv) o pertencimento aos níveis diferenciados de
governança corporativa impactam positivamente as empresas que distribuem menos dividendos
e negativamente as empresas que distribuem mais dividendos; e v) as variáveis relacionadas a
rentabilidade e endividamento não apresentaram bom desempenho para explicar a política de
dividendos das empresas. Já quando olhamos para cada setor de atuação, os resultados apontam
que: i) em geral, o tamanho do ativo é positivo, crescente e significativo para a maioria dos
quantis considerando ambas as variáveis dependentes; ii) PIB, CDI e Câmbio apresentam bom
desempenho para explicar a política de dividendos das empresas; iii) as características de
controle relacionadas ao endividamento, liquidez, risco e rentabilidade apresentam relações
diferentes para cada setor; iv) características relacionadas ao controle acionário e pertencimento
aos segmentos diferenciados de governança corporativa indicam a presença de efeito clientela
e de sinalização na política de dividendos das empresas a depender do setor de atuação
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
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.
