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
Economy-wide analysis of regulatory and competition policy a prototype general equilibrium model*
Full text linkThis document describes the structure and behaviour of a numerical comparative static model of an almost small open economy with five primary factors and any number of product markets. Unlike most such models, all firms in all sectors are oligopolistic in behaviour, with the degree of product market power depending on the size of recurrent fixed costs per plant, the elasticity of demand faced by each and the level of strategic interactions between firms, as captured by calibrated conjectural variations parameters. Demand facing each firm comprises final consumption, intermediate use and exports, each of which is differently elastic. Physical capital earns a constant, international, rate of return and the length of run is set so that the home capital stock is flexible. Shocks that raise the home capital stock, however, also raise foreign ownership. The policy instruments currently represented are tariffs, export taxes and export subsidies
China after the crisis: the elemental macroeconomics
Full text linkAlthough the ‘country runs’ of the Asian crisis stopped at the Chinese border, their effects nonetheless included a realignment of real exchange rates and a rise in the risk premium demanded of investments in China. These appear to have combined with a rise in the domestic savings rate of slow the country’s economic growth and its rate of labour absorption. The government’s macroeconomic policy responses were to fix parity with the US dollar, undertake a fiscal expansion and, more recently, raise the minimum wage. This paper uses an elemental comparative static model, combining graphical with numerical analysis, to examine the changes in the Chinese economy due to the crisis and the contemporaneous domestic shocks

Searching under the Light: The Neglect of Dynamics and Risk in the Analysis of Food Trade Reforms
Full text linkThe substantial investment in models of global food markets immediately prior to and
during the Uruguay Round of international trade negotiations has been a mixed blessing so far as the
prospects for reform are concerned. At worst, results from these models have misled the negotiations, first
because they have served the losers from reform better than the gainers and second because they have
tended not to address a primary concern lending domestic political support to food market interventions,
namely the avoidance of risks borne of dependence on international markets. The paper reviews some
errors that have stemmed from the application of "standard" but inappropriate models and examines the
implications of extending the standard methodology to include the combination of explicit food price risk
with dynamic behaviour and market-insulating policies
