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
What Drives the Profitability of Insurance Companies in Tanzania? An Empirical Analysis Based on Panel Data
Full text linkThis study examined the drivers of the profitability of insurance companies in Tanzania. Subjecting secondary data extracted from the Annual Insurance Performance Report issued by the Tanzania Insurance Regulatory Authority to analysis, the study found the sample to be unbalanced as it did from 2011 to 2020. Nevertheless, it yielded 218 firms’ year observations for analysis. Moreover, the study employed panel data regression models to calibrate the influence of the drivers on the profitability of insurance companies. The results indicate that market share and net premium significantly and positively correlated with the profitability of insurance companies in Tanzania. Furthermore, the study found a significant converse relationship between incurred claims and the profitability of insurance companies in Tanzania. Based on the research findings, the study recommends that the executives of insurance companies should expand their market share using marketing penetrating strategies to boost profitability. Likewise, they should strive to manage efficient incurred claims as they affect conversely the profitability of insurance companies

Accrual Quality and Stock Price Informativeness: Evidence from India.
Full text linkThis study examines the relationship between accrual quality and stock price informativeness. Study used secondary data collected from prowess database similar to prior studies Ansari &Khan 2012 and Dhole, et al. 2012. The study used sample of 91 companies listed in BSE 100 during the period of 2007 to 2011. We employed Breusch-Pegan Lagrange multiplier (LM) to select panel regression model and also eliminate the effect of outliers by deciles rank of accrual quality similar with prior study (Johnston 2009 and Jing 2007). We employed random effect panel regression model to investigate relationship between accrual quality and stock price informativeness. The results suggest that accrual quality is positively related to stock price informativeness. The present findings are similar with Jing (2007) and Johnston 2009 who find positive significantly association between accrual quality and stock price informativeness in USA. Results support that accrual quality matters in the process of incorporating firm specific information. Keywords: Stock price informativeness, Stock price synchronicity, Earnings quality, and Accrual quality: synchronicity and informative will be interchangeable to mean inverse of each other
