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
The relationship between ownership structure as well as CEO power and firm performance and risk taking: evidence from Pakistan
No full textThe business sector of Pakistan is under-performing and there is a series of mega financial scams in the corporate sector of Pakistan. The current study argues that firm performance can be affected by many firm specific variables including ownership structure, CEO duality and independent directors. These firm specific variables can affect firm performance and overall firm risk and can also determine the risk preferences -low, medium and high - by different types of shareholders. The main focus of the study was to investigate the impact of ownership structure, CEO duality and independent directors on firm performance, firm risk and return to risk of the firm in the light of the agency theory. Therefore, to serve this purpose, data from the annual reports of 284 out of the 440 companies listed on the Pakistan stock exchange between 2010 and 2014 were collected based on data availability. Panel data analysis technique was used to test the hypotheses of the study. The study showed that family ownership, CEO duality and independent directors have no significant relationship but institutional, foreign and ownership concentration have significant relationships with firm performance. On the other hand it showed that family ownership, CEO duality and independent director do not have any significant relationship with firm risk. However, foreign ownership, institutional ownership and ownership concentration have significant relationships with firm risk. The study also showed that none of the type of ownership is significantly related to low, medium and high firm risk except ownership concentration with medium risk .On the other hand the study found that none of the type of ownership (family, institutional, foreign and ownership concentration) is significantly related to return to risk of the firm. The study also found an insignificant moderating effect of CEO duality between the relationship of ownership structure and firm performance. This study strongly raises questions about the implications of the agency theory in the corporate sector of Pakistan, as only three out of forty, main and sub-hypotheses, were accepted. The study calls for a new theory considering the behavioural and other market specific dynamics in the market settings of developing countries such as Pakistan
Nef Antibody Phage Display as a Screening Tool for Novel Therapeutics Against HIV.
Get PDFNef is an accessory protein of HIV-1 virus, which plays a critical role in the pathogenesis of AIDS. Nef augmer the HIV infection by dysregulating the immune system of the infected human(s). Nef is present on the surface of the infected cells and it is also secreted in exosomes (Nef-exosomes) into intracellular spaces
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
