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
Banking Regulation for ESG Principles and Climate Risk
No full textNowadays banking activity is greatly influenced by environmental and social
conditions. For this reason, regulators have been committed to defining Environment,
Social, and Governance (ESG) principles. In addition, climate change has shown the
relevance of climate risks that have relevant implications in the new risk management
process. The 2030 Agenda for Sustainable Development is based on the 17 SDGs that
are, in the next future, the main challenge for the worldwide economy as they will be
the basis for real sustainable activities. In this context, banks play a very relevant role
as they have the power to lead this new challenge and are able to facilitate businesses
to run toward a sustainable green economy. For this reason, banks’ activity is now
oriented to increase and allocate credit and investment to more sustainable sectors.
As climate risk is, at the same time, cause and effect for a socially responsible activity,
regulators have been considering the role of banks for the green and ecological transition,
which is necessary to face this new risk. The chapter is an overview of rules,
regulations, and guidelines for banks referred to ESG principles and their adoption
in a global perspective; it also refers to climate risk that, due to its components, may
require further capital to preserve banks’ stability
Deposit guarantee reform in Europe: does European deposit insurance scheme increase banking stability?
No full textThe financial crisis led to reforms of regulation and supervision in Europe, including Deposit Guarantee Schemes. The new rules for DGSs define their position and interaction within the safety net. DGSs form part of a system to maintain and enhance
financial stability. According to the Five Presidents’ Report a European Deposit Insurance Scheme should be the third pillar of the Banking Union. The paper gives a contribution to the on-going debate providing an assessment of the DGSs reform
and its evolution towards EDIS. It explains key elements of the new rules for DGSs putting them in a systemic perspective
The Technological Disruption in Banking Sector - New Efforts and Challenges in the Financial Business Models
No full textThe disruptive technologies radically transform business models and create new innovative products and services. The chapter, focused on the technological disruption in banks, considers: • the assessment of technology impact, including the spread of artificial intelligence, at the level of business models and the relevance for regulators and supervisors, interested in granting a safe and sound banking system; • the main risks associated with technology considered in banking business models;• future perspectives for new strategies and business models with a transition from linear vertically-integrated models to non-linear adaptive models. The chapter outlines the state of the art in the banking services and the organizational responses, highlighting the needs not yet solved in banks' operations, but projected towards the near future, already present. The Appendix offers a framework of the banks’ approach to technology through the answers given by the sample of European banks to questions about technology in EBA’s RAQ
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
