Kinematic changes during learning the longswing on high bar

The purpose of this study is to provide evidence of technique changes during learning a sports-specific skill, the looped bar longswing (LLS). Thirteen male participants with no previous high bar experience took part in a training study. Kinematic data were collected using a CODA motion analysis system (200 Hz) during eight weekly testing sessions. Analyses focused on the amplitude of swing and the functional phase (FP) actions, defined by the rapid flexion to extension of the shoulders and extension to flexion of the hips as the performer passed through the lower vertical. Three groups were identified based on the number of sessions it took each participant to perform the LLS (G1: most successful, G2: intermediate, and G3: least successful). All participants were able to significantly increase swing amplitude over the training period (p < 0.05). For each participant the hip FP started significantly: later for G1, earlier for G2, and did not change for G3. Extension actions at the shoulders were dissimilar to those reported for elite gymnasts performing the longswing. The FP of the hips provides a mechanism to distinguish between the learners of different skill levels. The study has provided support for a single-subject design when investigating technique changes during learning.     

Hirsch-type characteristics of the tail of distributions. The generalised h-index

In this paper a generalisation of the h-index and g-index is given on the basis of non-negative real-valued functionals defined on subspaces of the vector space generated by the ordered samples. Several Hirsch-type measures are defined and their basic properties are analysed. Empirical properties are illustrated using examples from the micro- and meso-level. Among these measures, the h-index proved the most, the arithmetic and geometric g-indices, the least robust measures. The μ-index and the harmonic g-index provide more balanced results and are still robust enough.     

Quantitative and qualitative approaches in educational research — problems and examples of controlled understanding through interpretive methods

In the methodological discussion of recent years it has become apparent that many research problems, including problems relating to the theory of educational science, cannot be solved by using quantitative methods. The multifaceted aspects of human behaviour and all its environment-bound subtle nuances, especially the process of education or the development of identity, cannot fully be taken into account within a rigid neopositivist approach. In employing the paradigm of symbolic interactionism as a suitable model for the analysis of processes of education and formation, the research has generally to start out from complex reciprocal social interactions instead of unambigious connections of causes. In analysing several particular methodological problems, the article demonstrates some weaknesses of quantitative approaches and then shows the advantages in and the necessity for using qualitative research tools.

Zusammenfassung In der methodologischen Diskussion der letzten Jahre hat sich gezeigt, auch im Hinblick auf Theorieprobleme der Erziehungswissenschaft, daß eine ganze Reihe von Forschungsproblemen nicht mit quantitativen Methoden in den Griff zu bekommen sind. Die facettenreichen Aspekte menschlichen Verhaltens, einschließlich seiner situationsbedingten Nuancen, insbesondere der Erziehungsprozeß oder die Entwicklung der Identität, sind mit einem rigiden neopositivistischen konzeptionellen Rahmen nicht angemessen zu begreifen. Wenn dagegen das Paradigma der symbolischen Interaktion als adäquates Modell für die Analyse der Erziehungs- und Bildungsprozesse genommen wird, muß die Methodologie generell von komplexen sozialen Wechselbeziehungen anstatt von eindeutigen Kausalbeziehungen ausgehen. Indem einige methodologische Probleme exemplarisch diskutiert werden, sollen in dem Artikel einige Schwachpunkte quantitativer Methoden demonstriert werden. Darüberhinaus sollen Vorteile und Notwendigkeit des Gebrauchs von qualitativen Forschungsverfahren dargelegt werden.

Résumé Il est apparu évident dans le débat méthodologique de ces dernières années que de nombreux problèmes liés à la recherche, y compris ceux relatifs à la théorie des sciences de l'éducation, ne pouvaient être résolus au moyen de méthodes quantitatives. Les aspects aux facettes multiples du comportement humain et toutes ses nuances subtiles liées à l'environnement, notamment le processus d'éducation ou le développement de l'identité, ne peuvent être retenus pour une approche néopositiviste rigide. En considérant le paradigme de l'interaction symbolique en tant que modèle convenable pour l'analyse des processus d'éducation et de formation, la recherche est généralement partie d'interactions sociales réciproques complexes plutôt que de relations de causes non équivoques. En analysant quelques problèmes méthodologiques particuliers, cet article révèle quelques faiblesses des approches quantitatives et montre les avantages et la nécessité de l'utilisation d'instruments de recherche qualitatifs.

A thousand tiny pluralities: children becoming-other than the requirements of postsecular neoliberal policy recognition

ABSTRACT

This paper critiques the idea that secular education policy can neutrally recognise children’s non/religious identities at school. It also empirically analyses how one child becomes restricted by, and eludes, classed, gendered and adult-centred moral codes enacted through local school recognition. The concept of policy assemblage is first used to problematise postsecular, market-led enactments of non/religious school community recognition transnationally. I argue postsecular policy enactments in Ireland and elsewhere produce viable and non-viable forms of non/religious school community, thus containing, rather than facilitating school plurality and (re)creating social hierarchies. However, drawing on Deleuzian ideas of becoming and partial objects, I argue children are not determined by the sense-making moral codes of the policy assemblage. To demonstrate this argument, I map instances of how one girl alters and eludes the meanings of austerity, choice and authenticity moral codes. I do not privilege this girl as an example of child resistance, as I argue against using children as barometers of policy authority and secularist authenticity. Instead, I contend that alongside naming and opposing policy’s unjust effects, we need to cultivate attention to our capacity to affect and be affected by the partial objects (e.g. moral codes) and becomings of postsecular neoliberal policy assemblages.
