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
Economic Meaning of a Labor Shortage
No full textKeynes pointed out that in a laissez-faire
economy geared to a high level
of investment spending, population
growth, via its effect on investment,
might be an important factor in maintaining
prosperity. He also showed,
however, that fiscal and monetary policy
could be used to counteract fluctuations
in private investment and thus
maintain a generally high level of income
and employment whatever might
be happening to population growth
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

Is the Population Bomb Still Ticking?
Get PDFRecent research on demographic history indicates that birth rate decline is not necessarily the result of economic development, and therefore there is reason for optimism about family planning programs
Interview with Alan R. Sweezy
Get PDFAn interview in two sessions in February-March 1982 with Alan R. Sweezy, professor of economics in the Division of the Humanities and Social Sciences. Professor Sweezy joined Caltech's humanities faculty in 1949, after having taught for several years at Williams College. He did his undergraduate and graduate work at Harvard. During the Depression, before joining the faculty at Williams, he worked in Washington helping to set up the new Social Security System, and later at the Federal Reserve Board. His interests in economic development led him to studies of population growth, and in the late 1960s he became active in Planned Parenthood, becoming national chairman in 1972. Along with Professor Harrison Brown, Sweezy was instrumental in launching Caltech's Population Program in 1970, sponsored by the Agency for International Development (AID). The program worked closely with the American Universities Field Staff to collect and analyze data on population growth and population policy in underdeveloped countries, and several influential conferences were held at Caltech in the early 1970s on these issues. In this interview, Sweezy recalls the genesis of the program and its demise in 1974, which he attributes largely to a change of focus in the humanities division. By then the division had shifted to a narrower and more mathematically oriented brand of social sciences; macroeconomics, with its larger studies of population, resource utilization, fiscal policy, etc., gave way to microeconomics. He also comments on the wide interests of his colleagues on the faculty and on the changes in the student body over the years
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
