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
Research on dual-class share structure system
No full textFor the development of the company, the founders and management often resort to issuing shares for financing, which inevitably leads to equity dilution and may endanger the founders' control over the company. To maintain control during financing, founders are increasingly adopting a dual-class share structure. Before listing, founders categorize shares into two types: one reserved for founders or majority shareholders, which are non-tradable but carry multiple voting rights per share; and another publicly issued, which can freely trade on the stock market but carries only one share one vote. Even after multiple rounds of financing under a dual-class structure, founders can still retain control of the company.
The dual-class share structure has become a popular corporate governance model for tech companies in the evolving capital markets. The Shanghai Sci-Tech innovation board has also begun to allow tech companies with dual-class structures to list, showing recognition of this structure. However, given China's current market environment and legislative background, the application of dual-class structures must be strictly regulated. This research first defines the basic concepts and historical development of dual-class share structures, then analyzes the potential legal risks and advantages based on Principal-agent theory, control rights theory, and shareholder heterogeneity theory. The thesis draws on the developmental history and legislative practices from the United States, Canada, Singapore, and Hong Kong to provide insights for implementing dual-class structures in China. This thesis also includes an empirical analysis of China concept stock listed in the U.S., assessing the impact of dual-class structures on corporate performance. Finally, the article proposes specific recommendations for establishing and refining dual-class share structures in China, including qualifying conditions for listing, enhancing supervision systems, improving the independent director system, strengthening information disclosure requirements, and establishing more comprehensive shareholder protection mechanisms to ensure that minority shareholders can obtain effective relief when their rights are infringed.published_or_final_versionLawDoctoralDoctor of Philosoph

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
