Who am I - and if so, where? An experiment on personality in online virtual realities
Virtual realities form a new technical platform, raising scientific questions about the human mind, communication and identity. There is hardly any scientific research on the influence of a virtual reality on the identity perception and the personality of a user of these virtual realities. The present study attempts to contribute to filling this gap by assessing the potential difference between real-life personality and the ‘virtual’ avatar personality using the online virtual world of Second Life. Dutch participants (N = 34) were asked to use their own avatar or create a new avatar within this online virtual reality, to communicate with other avatars and finally to fill in a Big Five personality questionnaire (5 Persoonlijkheids Factoren Test - 5PFT) via a virtual interactive testing screen within Second Life. The virtual 5 PFT scores were compared to pencil and paper scores of the same questionnaire, which had been filled in by all 34 participants during a first-year undergraduate test battery, seven months prior to the virtual testing. Results showed no difference for any of the five subscales (extraversion, friendliness, conscientiousness, neuroticism, development) between the pencil and paper and the virtual version, suggesting that users of virtual realities do not create a ‘virtual’ personality for their avatar. Furthermore, high scores of internal consistency and high test-retest correlations between the two versions were found, which are very similar to the original test-retest scores of the 5PFT. These findings show the potential of virtual realities as new platforms for reliable (psychological) testing and future clinical applications
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
From a general interest to the state of the art using AI tools: guiding notes
This document is intended to support students in the initial stages of research, particularly in courses dedicated to the planning of master's dissertations and doctoral theses. It proposes that identifying the state of the art in a problem (and its associated techniques) be understood as a dual process: technical and personal. On the technical level, it involves understanding the current point of knowledge (what advances have been made, which techniques are in use, and how to apply them); on the personal level, the focus is on exploring alternatives and leading the student-researcher to reflect on their priorities, ambitions, and constraints. The goal is to empower them to make informed and conscious choices about the contours of the problem and the technical-scientific goals to pursue.

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
