Excavation of the mid-fifteenth-century castle of Pieter Bladelin, a high-ranking Burgundian official, in the village of Middelburg-in-Flanders, near Bruges (Belgium), has unearthed a remarkable series of blue and white painted and glazed floor tiles. Post-excavation archival and heraldic inquiries into the tiles has led to a deeper understanding of the role that gift exchange of luxury objects played within the diplomatic network of Alfonso V “the Magnanimous”, King of Aragon, and Philip “the Good”, Duke of Burgundy, in shaping a shared chivalric and crusading culture between Burgundy and Aragon. The study demonstrates the added value of the integration of archaeological and historical data in studying economic, political and cultural processes for the later medieval or early modern period. 相似文献

Reliability of unipodal and bipodal counter movement jump landings in a recreational male population
Cédric Schwartz Bénédicte Forthomme Julien Paulus Jean-François Kaux Olivier Brüls Vincent Denoël 《European Journal of Sport Science》2017,17(9):1143-1152
Movement patterns during landing have been suggested to be related to injury risk. The purpose of this study was to determine the inter-session reliability of kinematic variables and ground reaction forces during landing in a population of male recreational athletes after a counter movement jump. Both unipodal and bipodal landings were evaluated. Furthermore, the possibility to improve landing reliability with a verbal instruction was also studied. Twenty-four male volunteers with no history of lower extremity trauma were randomly assigned to two groups (with and without verbal landing instruction). An optoelectronic 3D system and force plates were used to measure the lower limb joint angles and the ground reaction forces during landing. Intraclass correlation values show moderate to excellent inter-session reliability for the bipodal task (ICC average: 0.80, range: 0.46–0.97) and poor to excellent reliability for the unipodal task (ICC average: >0.75, range: 0.20–0.95). However, large standard errors of measurement values at the ankle joint at impact (27.6?±?11.5°) and for the vertical ground reaction forces (394?±?1091 N) show that some variables may not be usable in practice. The verbal instruction had a negative effect on the reliability of unipodal landing but improved the reliability of bipodal landing. These findings show that the reliability of a landing task is influenced by its motor complexity as well as the instruction given to the subject. 相似文献

This paper proposes a typology of communities of practice based on their knowledge characteristics. The structure of a community of practice, in terms of knowledge, may tend to the stratified or to the egalitarian. The predominant knowledge activity of the community may be sharing or nurturing. This produces four classes of community of practice. The paper identifies and discusses examples of these classes. It is argued that the class to which a community belongs tends to determine the rapidity with which knowledge within the community evolves and the degree of pluralism, as opposed to homogeneity, that the knowledge exhibits. The paper concludes by discussing some of the implications of the typology for knowledge management practice. 相似文献

Prior to large experimentations on the teaching of probability theory, it appeared useful to observe some students working for a fairly long time. This observation should make more precise the difficulties of an important aspect when solving probability problems: the modelling aspect. Does systematic use of simulation produce miracles as it is sometimes said? Are the students naturally sensitive to a frequentist approach of probability theory? This paper contains some results on these questions, for example we pointed out for some students an obstacle to the frequentist approach. The results permit to conceive how using simulation for teaching could contribute to an improvement of students' approach to probability. 相似文献
