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
The double edge of networks. An analysis of the effect of informal networks on cooperation in social dilemmas
Full text linkEen sociaal dilemma is een situatie waarin gemeenschappelijke belangen en de uiteenlopende individuele interesses van leden van een groep conflicteren. Volgens talrijke sociaalwetenschappelijke studies helpt een hecht netwerk van informele sociale relaties een groep bij het oplossen van een sociaal dilemma. Of, in termen van Homans (1974) gezegd: bevordert groepscohesie de bereidheid van individuen om collectieve verplichtingen na te komen. ....

Commitment and evolution: connecting emotion and reason in long-term relationships
Full text linkLong-term interpersonal relationships are everywhere. People instinctively establish contact with strangers, invest in getting to know each other, and often go to great lengths to avoid losing existing relationships. Many relationships yield obvious benefits for involved parties, monetary or otherwise, and it is only rational to establish and maintain them. Yet, it sometimes seems difficult to find rational explanations for the existence or continuation of certain relationships in which people ignore their own instrumental interest and practical advantages. The apparent explanation for such seemingly irrational behavior is that, with regard to relationships, people are especially prone to act under the influence of emotions. It has been argued, in fact, that many of the strongest emotions people experience in life, both positive and negative, are somehow linked to relationships.
This work attempts to answer why such emotions came to diverge from rationality in the first place. Building on previous work, we use evolutionary theory and computer simulations to provide mathematical models of relationship-building, and to thereby compare different strategies with regard to commitment to long-term partners. Subsequently, we test some of the implications of these models using human subjects in controlled cross-cultural experiments.
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
