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
Ireland’s National Asset Management Agency (NAMA) and the British property market: Disposing of crisis
No full textA watershed year for the global economic system, the year 2008 also marked the demise of what had been broadly heralded as the ‘Celtic Tiger’ economic miracle as a triple crisis (financial, fiscal and banking) took hold in Ireland. Through the early 2000’s, much of the ‘growth’ sustained by a speculative property bubble facilitated in part by generous mortgage relief . The easy availability of credit coupled with low interest rates and fiscal incentives for property development, that had long run their course, fuelled the construction boom: in Ireland, at its peak, the number of houses completed was somewhere between 33-50% the number of homes being built in the UK. Whelan has calculated that “the total stock of mortgage loans in Ireland exploded from €16 billion in 2003:Q1 to a peak of €106 billion in 2008:Q3, about 60 percent of that year’s GDP” . A growing dependence on consumption-based taxes, became apparent with property-based taxes accounting for 20% of all Irish tax revenue in 2006. By the late 2000’s, property supply ‘overshot’ what was required, the market stagnated, and credit was closed off. Rather than relying on deposits, banks had engaged in high-risk practices borrowing short from the international money markets to lend to long-term projects, leaving the sector exposed when the global financial crisis and credit crunch hit in 2008. In response, the Irish government in September 2008 issued a blanket guarantee of the Irish domestic banking system in an effort to stem the withdrawal of large deposits and help facilitate capital raising. In early 2009, Anglo-Irish Bank was nationalised and three other banks recapitalised. Nonetheless the scale of their exposure was such that while loans made to property developers remained on their books, domestic banks could not raise funding nor stem capital outflows. In an effort to address the critical uncertainty regarding the banks’ exposure to property related loans, and facilitate the recovery of the sector, the Government announced the establishment of the National Asset Management Agency (NAMA) in an emergency budget in April 2009
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

Offshoring the Nation's water
Get PDFWhen the ten regional water authorities in England and Wales were floated on the London Stock Exchange in 1989, a shift in ownership inevitably followed from the privatization of household water. The public listing of shares in water companies initially created a wide distribution of ownership across the UK population, with preference given to those who paid the water bills. Controls were put in place to ensure that no one individual or company could monopolize the shareholdings, with the UK government retaining a ‘golden share’ precisely to avoid such an outcome. Once those shares were relinquished by the government in 1994, however, the ownership of the nation’s water started to shift abroad, with foreign investors largely attracted by the low risk, stable returns on offer. Some two decades on, with seven of the ten water authorities now in foreign ownership, the contrast from the idea of a British shareholding public that drove the early UK privatisations could not be greater
