How youth soccer players think about playing the game
Youth soccer players speaking about how they solve game related problems
Game understanding
Understanding in general, and tactical understanding in particular, is an important target for coaches in children’s sport. Accordingly, this study aimed to test how one team of Under 13-14 soccer players’ depth of game understanding changed over time using a multi-methods approach with multiple data points over an 18-month time period. Players’ (n=10) experienced coaching methods aimed to enhance metacognition, which were deployed in varying doses throughout the study duration. Testing occurred on four occasions using Applied Cognitive Task Analysis (ACTA) to uncover how young players think when playing soccer, combined with a Game Understanding (GU) comparative rating scale criterion. In parallel, the players’ coaches (n=3) performed quantitative measures of GU using the criterion, and analysis deployed a repeated measures ANOVA to compare significant changes. Analysis of ACTA interviews used a deductive framework focussed on metacognitive game skills and metacognitive strategy. Our results clearly show that players’ depth of understanding significantly improved during and post exposure to coaching methods which sought to enhance metacognition. Post the initial intervention, understanding improved at a steady but not significant rate. Qualitative findings showed that players’ metacognition became more sophisticated as time went on, with a particular improvement in strategising based upon their team mates and the opponent’s capabilities. Overall, this study shows that young soccer players are capable of both using metacognition when playing, and developing their metacognition over time.PRE - Player 1, Player 2, Player 3, Player 4, Player 5, Player 6, Player 7, Player 8, Player 9, Player 10

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
Dispelling the Myths Behind First-author Citation Counts
We 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
