Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
To what extent can early life experience explain prosocial and pro-environmental behaviour?
Human beings evolved an intensive caregiving system to help children develop and mature. This system, known as the evolved nest, includes practices such as extensive positive touch, responsive care, and free play. People’s early life experience of the evolved nest (their ‘developmental nestedness’) has previously been associated with self-reported prosocial behaviour. Here we test whether developmental nestedness is associated with prosocial and pro-environmental behaviour by recruiting participants to complete both standard and real-world public goods games. We also test the extent to which developmental nestedness is associated with pro-environmental behaviour at different levels by randomly assigning participants to one of three treatments in which they have the opportunity to donate money to a local, national, or global reforestation charity. We explore the role of developmental nestedness through the lens of the ABC model, which states that cooperation (C) is a function of attitudes (A) and beliefs (B)
Averting Disaster: The Effect of Relative Resilience in Merit-Based and Luck-Based Worlds
Many of our greatest challenges in society require collective action. One example is reducing global greenhouse gas emissions – a task that requires nations to make individually costly but collectively beneficial contributions towards this common goal. There is no straightforward answer to the question of how much each country ought to contribute. One complicating factor, among many, is that different countries may believe themselves to be more resilient or vulnerable to the effects of climate change than others. In this study we explore the impact of these beliefs. In particular, we investigate whether the perceived origin of these inequalities in vulnerability – specifically, whether they are merit-based or luck-based – influences individual contribution behaviour and group coordination. We use an adapted version of the collective-risk social dilemma, a public goods game first introduced by Milinski et al. (2008), to investigate this question
