The impact of music downloads and P2P file-sharing on the purchase of music in Canada
No full textThis study measures the extent to which free music downloads, including the use of P2P file sharing networks, act as substitutes or complements to music purchase in markets for CDs and electronic delivered music (such as MP3).
The analysis uses representative micro-data from the Canadian population. We find that those who participate in free music downloading and P2P file-sharing do not purchase more or less music compared with those who do not engaged in such activities, but that, indeed, very active file-sharers purchase more music relative to file-sharers who download fewer songs. Thus, the market substitution effect between freely acquired music and purchased music is smaller than the market creation and market segmentation effect from free music downloading. In essence, the behavioural incentives underpinning free music downloading are the effects of ‘unwilling to pay’ (market substitution), ‘hear before buying’ (market creation), ‘not wanting to buy whole album’ (market segmentation), ‘not available in the CD format or on electronic pay-sites (market creation)’
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
Public interest and the public domain in an era of corporate dominance
No full textBook synopsis: There is a growing need to understand the role of the regulation of intellectual property rights (IPRs), in order not only to achieve economic performance, growth and sustainable development at corporate, sectoral and global levels, but also to provide a higher quality of life for communities worldwide.\ud
\ud
Intellectual Property Rights is cutting edge in addressing current debates affecting businesses, industry sectors and society today, and in focusing not only on the enabling welfare effects of IPR systems, but also on some of the possible adverse effects of IPR systems. The main areas covered in the book are: \ud
\ud
• the global commons in an era of corporate dominance and privatisation of the public domain, including science, culture, and healthcare under TRIPS\ud
• the rationales for IPRs, and the importance of an appropriate design of an IPR regime in achieving its objectives\ud
• opening the black box of IPR offices and critically reviewing how they affect economic performance in both theory and practice\ud
• coordinating the institutions (state versus sector institutions, knowledge networks, innovation systems) creating and extracting financial and non-financial value from patents and copyrights. \ud
\ud
This book challenges the existing mainstream thinking and analytical frameworks dominating the theoretical literature on IPRs within economics, management, politics, law and regulation theory. It is relevant for policymakers, business analysts, industrial and business economists, researchers and students
