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

No full textUnlocking success: exploring the relationship between multiple CSR initiatives, firm performance and the role of the regional quality of government
No full textPurposeFollowing signalling theory, this paper aims to study the impact of multiple corporate social responsibility (CSR) initiatives on firm performance, by considering commitment to the United Nations Global Compact (UNGC), the Occupational Health and Safety Assessment Series (OHSAS) 18001 and environmental commitment such as Kyoto Protocol or Paris Agreement, for a sample of Italian-listed companies. Through the adoption of contingency theory, the paper also aims to study whether the impact of CSR initiatives is moderated by the following contextual factors: quality of government, impartiality and corruption of the region. Information on CSR initiatives is obtained through a manual content analysis of companies' disclosure.Design/methodology/approachStudying a sample of Italian-listed companies, information on CSR initiatives is obtained through a manual content analysis of companies' sustainability or integrated reports. The authors run ordinary least square regressions to test research questions.FindingsResults show that OHSAS 18001 has a positive influence on both sales growth and profitability when held alone. When the focus is on one single initiative, stakeholders tend to attribute more value to signals of the social dimension. This evaluation can be enhanced by combining OHSAS 18001 with firm commitment to UNGC and/or the Kyoto Protocol or Paris Agreement. By signalling a more comprehensive approach to CSR, firms can obtain reputational growth, which can generate competitive advantage. Finally, in regions with low corruption, high impartiality and high government quality, CSR initiatives are considered as more reliable signals, which further enhances firms' performance.Practical implicationsThese results may have practical implication for managers as they confirm that using OHSAS 18001 certification ensures better performance. However, signalling commitment to a specific CSR initiative does not automatically imply an improvement in performance. Indeed, companies need to approach CSR initiatives in a strategic manner and may need to adjust their structure and philosophy to the principle of the initiative. Using a certification scheme has specific costs, which need to be considered.Social implicationsFindings show that the impact of CSR initiatives is affected by contextual factors such as the quality of government. Knowing this, firms could not be interested in sustainable practices in regions with low quality of government. In this sense, policymakers and regulators should enhance the quality of their activity to improve the foster firms' commitment to CSR. A higher firms' commitment can be beneficial to the entire community.Originality/valueTo the best of the authors' knowledge, this paper is the first attempt to identify how the combination of multiple CSR initiatives affects corporate performance. In addition, this paper analyses the impact of commitment towards global environmental policies on firms' performance. Then, the authors offer insights about if and how regional differences in terms of quality of government can moderate these impacts
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
