Gender:Disentangling Talent Identification and Development in Women’s and Girls’ Soccer
No full textDespite the increased growth and professionalism of women’s and girls’ soccer in recent years, there is still a paucity of research exploring talent identification and development. It is widely acknowledged that growth and maturation influence the biopsychosocial development of girls and boys differently, which has important implications for talent identification and development in soccer. Therefore, this chapter disentangles gender by providing an overview of existing research in women’s and girls’ soccer as well as offering recommendations for talent identification and development practices. Firstly, the chapter explains how growth and maturation may impact physical development of young female soccer players. Secondly, the chapter considers the psychosocial development of female players. Lastly, the chapter proposes directions for future research and outlines implications for practice
Technical:Examining subjective and objective performance parameters that contribute towards developmental outcomes and career progression
Full text linkSoccer is a sport that is comprised of many complex technical actions. In the context of youth soccer, these features have historically been measured and evaluated subjectively through the ‘coach’s eye’. However, objective tools are becoming increasingly more common to help compliment coaches’ opinions as resources and technologies continue to evolve. Moreover, current research has illustrated how the technical demands of contemporary soccer have enhanced significantly in recent years, which may have important implications on the talent identification and development processes at youth levels. Thus, the purpose of this chapter is to underscore the subjective and objective performance parameters that contribute towards developmental outcomes and career progression in youth soccer. Specifically, the current literature is synthesised and focused on four key areas, including: (a) technical testing, (b) performance analysis, (c) indicators of potential and recruiter perspectives, and (d) laterality. Following the overview of these technical fields, possible directions for future research and considerations for applied practice are proposed
Activities and Trajectories:Exploring Pathways of Athlete Development in Youth Soccer
No full textPathways towards expertise in soccer can differ due to the diverse activities and trajectories that players engage in throughout childhood and adolescence. As in many other sports, researchers and youth soccer stakeholders are currently faced with a myriad of issues surrounding the competing developmental pathways of early specialisation and early sampling. For these individuals, early specialisation can be summarised as the intensified participation in soccer and soccer-specific training to the exclusion of other activities, whereas early sampling could be described as participation in soccer as well as a variety of other sports at varying levels of competition and intensity. A large and continually growing body of research exists describing both the benefits and drawbacks of each contrasting developmental pathway. The purpose of the present chapter is to assess prominent works within this literature in an attempt to help those involved with youth soccer programming (e.g., athletes, parents, coaches, administrators) to make informed decisions around what optimal participation might look like. Research outlining how each trajectory relates to player’s overall personal development as well as their soccer specific development will also be discussed. Based on the evidence presented, considerations for researchers and practitioners will be offered.<br/
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
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
