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
Prospensity to pay dividend : testing for life cycle and free cash flow theories
Get PDFThe purpose of this study is to provide evidences in context of life cycle and free cash flow theories. The study examines the potential factors of firms to pay dividend by conducting logistic regression with sample of 138 firms listed in Indonesia Stock Exchange for period 2010 till 2015. The result of analysis shows that dividend payers generally are firms at mature stage which is consistent with life cycle theory. Also, these mature firms normally are larger firms, more profitable, higher earnings, higher debt and diminish for investment opportunities. In addition, the higher debt for dividend payers indicates the existence of free cash flow effects.peer-reviewe
Agent, steward, and dividend policy
Get PDFPurpose: The main objective of this study is to examine whether the dividend policy of Indonesian firms is based on agency theory or stewardship theory. The study investigates the relationship between profitability, non-discretionary accruals, discretionary accruals and dividend policy.
Design/Methodology/Approach: The final sample of this study is a total of 28 firms of consumers‘ goods industries listed in Indonesia Stock Exchange during the period of 2010 to 2017 and conducts logistic regression for hypotheses testing.
Findings: The result of the first model shows that ROA and non-discretionary accruals (non-disc) have positive sign and they are significant on dividend policy. The second model shows that ROA has a positive and significant effect on dividend policy, while non-disc is insignificant on dividend policy. The third model shows that ROA and non-disc are consistently positive and significant, while discretionary accruals are consistently insignificant on dividend policy. The fourth model shows that ROA and non-disc have positive sign and significant on dividend policy, while disc is insignificant on dividend policy. The fifth model shows that ROA and non-disc have a positive and significant sign on dividend policy, while DAR, AG and disc are insignificant on dividend policy. The results of profitability on all models also indicate that the objective of managers for most Indonesian dividend payers are align with the objective of stockholders in context of stewardship. The findings imply that most of firms as payers tend to increase dividends when their profitability increases.
Practical Implications: It appears that dividend payers with strong profitability as based on their policy, generally do not engage in managing its earnings while reporting the accounting information. Originality/Value: The study provides empirical evidence for dividend policy in context of agency and stewardship perspectives. This study also identifies the behavior of firm insiders whether play as an agent or steward in relationship with their principals.peer-reviewe
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
