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
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
Precariedad laboral y voto de castigo en España: en defensa de un modelo de interacción entre los condicionantes económicos e ideológicos del voto
No full textEste artículo analiza los efectos de la precariedad laboral asociada al segmento flexibledel mercado de trabajo español sobre la intención de voto al final de la última legislaturasocialista. Para ello, se defiende un modelo de votante que interpreta sus experienciaseconómicas a través de prismas ideológicos y que, por tanto, no responde electoralmentea sus condiciones económicas al margen de dichos prismas. Este modelo de votante, queplantea la existencia de interacción entre los condicionantes económicos y los condicionantesideológicos del voto, se discute en contraposición a los modelos de votante económicoaditivos, que asumen que los condicionantes económicos tienen un impacto sobreel voto directo e independiente de la ideología de los electores. Ambos modelos se contrastanempíricamente a través de la explotación estadística de la encuesta de CulturaPolítica, realizada por el Centro de Investigaciones Sociológicas en abril de 1995 a unamuestra de casi 4.000 entrevistados. El análisis de estos datos da sustento empírico almodelo interacción y sugiere que la precariedad laboral pudo favorecer la aparición dedos tipos de castigo: (1) castigo al PSOE, entonces en el gobierno, tanto por la izquierda(votando a IU), como por la derecha (votando al PP), entre electores ideológicamentecercanos a este partido; y (2) castigo a todos los partidos, vía abstención crítica, entreelectores ideológicamente extremistas.<br /
Domestic Supply, Job-Specialization and Sex- Differences in Pay
No full textABSTRACT This paper proposes an explanation of sex-differences in job-allocation and pay. Joballocation calculations are considered to be related to 1) the distribution of housework and 2) the skill-specialization requirements of jobs. Both elements combined generate a particular incentive structure for each sex. Welfare policies and services can, however, lower the risks of skill-depreciation for women as well as increase their intra-household bargaining power, hence reducing the economic pay-offs of "traditional" spherespecialization by sex. The implications of this model for earnings are tested using data from the second round of the European Social Survey. Results seem consistent with the model predictions
