Modelling itself on the organizational structure and the physical fitness culture of Catholic scouting, the xaveri movement in Rwanda developed within a climate which was highly susceptible to the development of deep racial and political divisions. Between 1954 and 1964, this Catholic youth organization was influential in the gestation of a Christian democratic culture which was one of the essential elements of the ideology behind the ‘Hutu revolution’. Covering the colonial to the postcolonial period and from the angle of the rise of the xaveri movement, this paper shows how the ‘Hutu revolution’ was a consequence of a liberation struggle from an imagined oppressor. This is in reference to colonial privileges attributed (until the end of the 1940s) to the Tutsi minority. However, and still from the perspective of the organization explored here, it seems that the model of the ‘civilised Tutsi’ targeted by the revolutionary Hutu movement was the essential referent of the more subconscious invention by republican leaders. 相似文献

The functional classification system for wheelchair basketball is based on an analysis of the players' functional resources through field-testing and game observation. Under this system, players are assigned a score of 1 to 4.5. The aim of this study was to determine if the wheelchair basketball player classification system reflects the existing differences in performance of elite female players. During the World Championship for Wheelchair Basketball in Sydney 1998, eight teams were videotaped for three 40-min games for a total of 120?min per team. Fifty-nine female players (Class I [1 and 1.5 points] n?=?12; Class II [2 and 2.5 points] n?=?20; Class III [3 and 3.5 points] n?=?13; Class IV [4 and 4.5 points] n?=?14) were retained for a detailed performance analysis by means of the Comprehensive Basketball Grading System (CBGS). Two-way analysis of variance showed high point players to perform better compared with low point players for the majority of variables determining the quality of game performance. A lack of significant differences between two adjacent classes was explained on the basis of the methodological approach, the class–position relationship in this sample, and the performance level of women's wheelchair basketball. We conclude that the performance of elite female wheelchair basketball players is dependent on functional ability. 相似文献

ABSTRACT At the turn of the millennium, a review paper was published in this journal on talent identification and development in soccer (Williams & Reilly, 2000). In the current paper, we assess progress made in this field over the last twenty years relative to the areas for future research highlighted in the original review. We evaluate developments in light of the calls made by Williams and Reilly to: a) undertake more multidisciplinary rather than mono-disciplinary research; b) embrace longitudinal rather than cross-sectional research designs; c) expand the research base on female football; and, d) better identify the subjective criteria used by scouts when selecting one player over another for entry into a formalised training environment. The body of mono-disciplinary research on this topic continues to expand, and progress has been made in publishing multidisciplinary, prospective, longitudinal data sets, along with advanced statistical modelling procedures, as well as in identifying the experiential criteria used by scouts. We found some variables in these studies have predictive value from adolescence to adult performance level in soccer. We present suggestions for future research to enhance knowledge and understanding of the best practices underpinning the identification and development of future generations of professional players. 相似文献
