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
Socially responsible investments and portfolio performance: a critical literature review
No full textSince its introduction in the early 1970s, socially responsible investment (SRI) has gained prominence as both a rival and a complement to conventional investment. SRI is the philosophy and practice of making strategic investment decisions by integrating financial and non-financial considerations, including personal values, societal demands, environmental concerns and corporate governance issues. One of the major concerns in socially responsible investing is whether there is a difference between the performance of socially screened portfolios and that of conventional funds.
This study is a literature review of socially responsible investment and portfolio performance. The objectives of the study are to establish the documented relationship between socially responsible investment (SRI) and portfolio performance; to investigate, from the literature, whether investor demographic characteristics moderate the relationship between socially responsible investment and portfolio performance, to examine whether the relationship between SRI and portfolio performance is intervened by portfolio management process, to identify and document research gaps in socially responsible investment and lastly to establish researchable issues in socially responsible investment. The study presents a conceptual model guided by the modern portfolio theory, the stakeholders’ theory, the institutional theory and the new social movement theory.
Literature reviewed on the performance of SRI mutual funds has been inconclusive with three schools of thought emerging: SRI under-performs, over-performs or performs as well as conventional mutual funds. The paper concludes that the conflicting results are caused by the fact that the relationship between SRI and portfolio performances is not direct but is intervened by other variables such as the portfolio management process. Five factors in the portfolio management process that are affected by SRI have been identified (Havemann and Webster, 1999). These are the portfolio diversification process, the size and structure of the investable universe, concentration and the research costs incurred in monitoring the investee companies. Another explanation into the conflicting results is that the relationship between SRI and portfolio performances may be moderated by the investors’ demographic characteristics such age, gender, level of education and amount of funds under management (Nilsson, 2008; Nilsson, 2009; Junkus and Berry, 2010).
A number of research gaps arise from the analysis of the issues examined in this paper. These include: Firstly, lack of consensus on why SRI occurs even when empirical evidence on the impact of SRI on portfolio performance is inconclusive. Secondly, difficulties in assessment of non-financial risk and return created by SRI especially given the inability to quantify social, ethical, governance, moral and environmental issues. Thirdly, most studies have not controlled for any intervening or moderating variable affecting the relationship between SRI and portfolio performance. Variables such as differences in demographic characteristics of the fund managers and portfolio management process may affect the relationship between SRI and portfolio performance.
Arising from the research gaps identified, several areas of further study have been suggested. These include: Firstly, a research instrument be developed to empirically test the variables that impact on socially responsible investment including the moderating and intervening variables. Secondly, a study can be undertaken to investigate the heterogeneity among investor clienteles and its implications for understanding the effects of social values on asset prices. Thirdly, given that investors have different reasons for investing in SRI profiled mutual funds, future research with regard to this segmentation would be to find out the reasons why investors belong to certain groups. Fourthly, further research can be done focusing on the type of mutual funds that could be marketed to the different investors’ segments and finally, an index can be developed to quantify the non-financial risk and returns existing in SRI mutual funds
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
