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
Over half a decade into the adoption of IFRS 9: a systematic literature review
No full textInternational audiencePurpose In 2018, the International Financial Reporting Standard 9-Financial Instruments became mandatory, effectively changing the underlying accounting principles of financial instruments. This paper systematically reviews the academic literature on the implementation effects of IFRS 9, providing a coherent picture of the state of the empirical literature on IFRS 9. Design/methodology/approach The study thrives on a systematic review approach by analyzing existing academic studies along the following three broad categories: adoption and implementation, impact on financial reporting, and risk management and provisioning. The study concludes by providing research prospects to fill the identified gaps. Findings We document data-related issues, forecasting uncertainties and the interaction of IFRS 9 with other regulatory standards as implementation challenges encountered. Also, we observe cross-country heterogeneity in reporting quality. Furthermore, contrary to pre-implementation expectations, we find improvement in risk management. This suggests that despite the complexities of the new regulatory standard on financial instruments, it appears to be more successful in achieving the intended objective of enhancing better market discipline and transparency rather than being a regulatory overreach. Originality/value As the literature on IFRS 9 is burgeoning, we provide state-of-the-art guidance and direction for researchers with a keen interest in the economic significance and implications of IFRS 9 adoption. The study identifies gaps in the literature that require further research, specifically, IFRS 9 adoption and firm’s hedging activities, IFRS 9 implications on non-financial firms. Lastly, existing studies are mostly focused on Europe and underscore the need for more research in under-researched jurisdictions, particularly in Asia and Africa. Also, to standard setters, policymakers and practitioners, we provide some insight to aid the formulation and application of standards
Essais sur la qualité de l'information financière et ses facteurs d'influence
No full textCette thèse se compose de trois essais qui visent à examiner la qualité de l'information financière et les facteurs d'influence. Le premier essai analyse l'impact de l'effet d’endettement sur la qualité de l'information financière dans le contexte des entreprises européennes. Nos résultats indiquent que l'effet d’endettement tente d'améliorer la qualité de l'information financière mais que les entreprises ont recours à des moyens plus créatifs pour manipuler les états financiers. Le deuxième essai examine le retard dans la publication des états financiers et vérifie si les retards sont des indications de la mauvaise qualité de l'information financière. Nos résultats confirment que dans un contexte européen, les entreprises qui retardent la publication de leurs états financiers ont une information financière de moindre qualité. Dans le troisième essai, nous étudions l'impact de la qualité de l'audit sur la qualité des états financiers dans le contexte des entreprises françaises. Nous constatons que la nomination de membres des Big4 n'améliore pas la qualité des états financiers.This thesis consists of three essays that aim to examine the quality of financial reporting and influencing factors. The first essay analyses the impact of leverage on the quality of financial information within the context of European firms. Our results indicate that leverage attempts to improve the quality of financial reporting but firms make use of more creative means to manipulate financial statements. The second essay examines the delay in the publication of earnings and ascertains whether delays are indications of poor quality financial information. Our results confirm that in a European setting, firms that delay in the publication of financials have a lower quality of financial information. In the third essay, we investigate the impact of audit quality on the quality of financial statements in the context of French firms. We find that appointing members of the Big4 does not improve the quality of financial statements
The impact of audit quality on earnings management: Evidence from France
No full textInternational audienceThis research investigates the relationship between financial reporting quality and audit quality within the context of French listed companies. The auditor brand name (Big4) is used as a proxy for audit quality and earnings management is ascertained through real and accruals earnings management estimation. Discretionary accruals are estimated using the Jones Model and the Modified Jones Model while real earnings management is estimated through the use of models proposed by Roychowdhury (2006). The results indicate that clients of Big4 audit firms record higher levels of accruals and real earnings management. This assertion could be attributed to the low level of auditor litigation risk in France. This study contributes to the literature by investigating the case for both discretionary accruals and real earnings management in a French environment that has peculiar auditing characteristics
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
