The adolescent motor performance development of elite female soccer players: A study of prognostic relevance for future success in adulthood using multilevel modelling

ABSTRACT

Considering the scarce empirical evidence regarding talent predictors in female youth soccer, the present study aimed to investigate the long-term prognostic validity of elite female soccer players’ adolescent motor performance for future success in adulthood. Additionally, the three-year development of highly talented girls’ motor performance and the predictive value of this motor development for reaching a professional adult performance level (APL) was analysed.

Overall, N = 737 female players participated in nationwide motor diagnostics (sprinting, agility, dribbling, ball control, shooting) within the German Soccer Association’s talent identification and development programme at least twice between the age groups Under-12 (U12) and U15. Based on their APL at least four years later, participants were assigned to a professional (first German division, 6.2%) or non-professional group (lower divisions, 93.8%).

Multilevel regression analyses revealed a general prognostic relevance for the investigated parameters with respect to players’ APL. In addition, there was a non-linear improvement in participants’ motor performance across all variables from U12 to U15. However, non-significant interactions between APL and these improvements indicate motor performance development itself cannot adequately predict players’ future success in adulthood. Findings provide insightful information that can help coaches foster optimal support for young female soccer players’ development.     

Usages and impacts of the integration of information and communication technologies (ICTs) in elementary classrooms: case study of Swedish municipality schools

During recent years, many schools have started to implement information and communication technologies (ICTs)-based learning devices (such as laptops, tablets, mobile phones, and active boards) in the classroom settings in order to increase learning outcomes. The aim of this study is to find which activities and outcomes are evident in the usages of computing devices and how those devices aid elementary-level students in their learning activities. The study includes five overt participant observations at some schools in a Swedish municipality including unstructured interviews and explains the findings through activity theory and the Alberta Education Framework for Student Learning . The major activities found were dealing with the (1) educational application assignments, (2) storytelling, (3) report writing and (4) practical interaction assignments. We concluded that ICTs aid students in becoming more concentrated, focus driven, engaged and amused, thus learning becomes more interesting.     

EDUCATION,FAIR COMPETITION,AND CONCERN FOR THE WORST OFF

In this essay, Johannes Giesinger comments on the current philosophical debate on educational justice. He observes that while authors like Elizabeth Anderson and Debra Satz develop a so‐called adequacy view of educational justice, Harry Brighouse and Adam Swift defend an egalitarian principle. Giesinger focuses his analysis on the main objection that is formulated, from an egalitarian perspective, against the adequacy view: that it neglects the problem of securing fair opportunities in the competition for social rewards. Giesinger meets this objection by expressing two basic theses: First, he argues that Brighouse and Swift themselves fail to give an adequate account of fair competition; and, second, he shows that the adequacy view provides the theoretical resources to face this problem.     

Can information ethics be conceptualized by using the core/periphery model?

The term ‘information ethics’ (IE) is rapidly diversifying as new technologies enter the milieu and add to already existing ‘entanglements’. Unsurprisingly, the term lacks a universally accepted definition, although there is some common ground as to its constitution. This paper explores the term using the most commonly co-occurring terms in IE literature as indexed in nine databases, namely the EBSCO-hosted Academic Search Premier (ASP); Communication and Mass Media Complete; ERIC; Library, Information Science and Technology Abstracts (LISTA); Newspaper Complete; Business Premier; and Master File Premier, and Wilson's Library Literature and Information Science (LLIS) Full Text. Core/periphery analysis, the co-occurrence of words as subject terms, and social network techniques were applied using UCINET for Windows, text STAT and Bibexcel computer-aided software to analyze data. The paper identifies the most common terms used to describe IE and the core terms with which IE can be defined. Other than informing LIS research and education, the results could potentially assist with the development of IE taxonomy and definitions (e.g. in understanding IE content and development) that may apply to the intercultural and global understanding of IE.     

How adolescents navigate Wikipedia to answer questions / ¿Cómo navegan los adolescentes en Wikipedia para contestar preguntas?

Abstract

In one experiment, we explored how high school students use hyperlink relevance cues while they navigate to answer questions from hypertexts. Current evidence has shown that students may navigate by either performing a deep semantic analysis of the relationship between the question and the existing hyperlinks, or by matching words in the question to words in the hyperlink labels. We focused on how students combine both cues during navigation, and how comprehension skills relate to the use of such cues. Our study revealed that 14 year old students (N = 53) selected hyperlinks by relying to a similar degree on both word matching and semantic overlap. Furthermore, when there was a conflict between an irrelevant link cued via word matching and a relevant link only cued through semantic overlap, students’ comprehension skills facilitated their initial selection of an informative relevant link. To conclude, we discuss the implications of these results for current models of hypertext navigation.     

Differences in the Processing of Prefixes and Suffixes Revealed by a Letter-Search Task

A letter-search task was used to test the hypothesis that affixes are chunked during morphological processing and that such chunking might operate differently for prefixes and suffixes. Participants had to detect a letter target that was embedded either in a prefix or suffix (e.g., ‘R’ in propoint or filmure) or in a non-prefix beginning or non-suffix ending (e.g., ‘R’ in cropoint or filmire). Prefixed and suffixed letter-strings comprised real stems and affixes but never formed a real word. Effects of letter cluster frequency were also investigated by manipulating the frequency of non-affix beginnings and endings. Letter search took longer in suffixes compared with non-suffix endings but not for prefixes compared with non-prefix beginnings. Moreover, performance was not affected by letter cluster frequency. We interpret our findings in the light of recent accounts of morpho-orthographic segmentation and the different function of prefixes and suffixes.     

Phonological recoding,orthographic decoding,and comprehension skills during reading acquisition

To become skillful readers, children have to acquire the ability to translate printed words letter by letter into phonemic representations (phonological recoding) and the ability to recognize the written word forms holistically (orthographical decoding). Whereas phonological recoding is the key for learning to read and useful for recognizing unknown or low-frequent words, orthographical decoding is often more efficient and takes less time, thus facilitating reading processes on the sentence and text level. Several studies with English-speaking children provided evidence for the relevance of the two routes but the question whether and to what extent both word recognition skills contribute to reading comprehension in young German readers requires further clarification. Based on data from a cross-sectional study with German primary school children we investigated whether and to what extent both types of word recognition skills are associated with sentence (N = 666) and text comprehension skills (N = 149) and how these relationships develop from Grade 2 to 4. The results indicate that both phonological recoding skills and orthographical decoding skills are important for reading comprehension skills. Their relative weight does not change across grade levels.
