Renormalization-group analysis for the transition to chaos in Hamiltonian systems

2002

Abstract We study the stability of Hamiltonian systems in classical mechanics with two degrees of freedom by renormalization-group methods. One of the key mechanisms of the transition to chaos is the break-up of invariant tori, which plays an essential role in the large scale and long-term behavior. The aim is to determine the threshold of break-up of invariant tori and its mechanism. The idea is to construct a renormalization transformation as a canonical change of coordinates, which deals with the dominant resonances leading to qualitative changes in the dynamics. Numerical results show that this transformation is an efficient tool for the determination of the threshold of the break-up of…

‘Disability Gain’ and the Limits of Representing Alternative Beauty

2018

In this conversation, Ann Fox, Matthias Krings and Ulf Vierke debate the concept of ‘disability gain’ and the limits of representing alternative beauty. The concept demands that we regard disability inclusion as a resource gain, instead of a resource drain. While this approach complicates and questions the societal definition and devaluation of ‘disability,’ it also raises a number of debatable issues. For example, what happens when ‘disabled’ bodies are commodified in an attempt to represent so-called alternative beauty? The conversation shows that, while the stakes for the fashion-beauty industry in extending aesthetic norms, pluralizing beauty and mainstreaming diversity are high, it man…

Duties, Rules and Interpretations in Obligational Disputations

2001

An obligational disputation, as it was known in the Middle Ages, consisted basically of a sequence of propositions put forward by one person, called the opponent, and evaluated by another person, called the respondent. In the most typical variations of the technique, the sequence would begin with a special proposition, called the positum It was taken as the starting point, which the rest of the sequence would develop. The respondent had to accept the positum, if it was free from contradictions. Then he had to take into account in his later evaluations of the other propositions that he must at any time during the disputation grant the positum and anything following from it. The disputations …

To correct or not correct the erroneous utterances of children: teacher‐initiated organisation of repair in the L2 pre‐primary education classroom

2010

ABSTRACT The research reported on a qualitative study of feedback given in one Finnish pre‐primary education group which integrated English into the programme as a first foreign language. The study was based on the authentic video‐recorded observations of actual pre‐primary teaching sessions (N = 11 lessons). The findings suggested that the reactions of the teachers to child errors depended on the types of errors made by children. The study discussed the tension present in feedback giving when balancing between the aim of maintaining the early interest of children in language learning and the purpose of paying attention to correct ways of using the target language. The data were analysed by…

La nature des compétences transversales développées par les étudiants de Licence et leur poids dans les parcours de réussite

2015

International audience; Cette recherche s'intéresse aux compétences transversales développées par les étudiants de Licence, et plus particulièrement au regard de leur situation vis-à-vis de l'activité rémunérée parallèle aux études. Le choix des compétences transversales évaluées découle de la classification proposée dans le référentiel des compétences comportementales Passeport Avenir (2011) qui propose pour chaque compétence une échelle de cinq niveaux, déclinés en fonction du degré de maîtrise chez l'individu, et décrits de manière précise par des exemples de réponse apportée à une situation. Une sélection a été opérée parmi les compétences sur le postulat que certaines retranscrivent da…

Effects of ions-releasing restorative materials on the dentine bonding longevity of modern universal adhesives after load-cycle and prolonged artific…

2019

This study aimed at evaluating the microtensile bond strength (MTBS) and fractographic features of dentine-bonded specimens created using universal adhesives applied in etch-and-rinse (ER) or self-etching (SE) mode in combination with modern ion-releasing resin-modified glass-ionomer cement (RMGIC)-based materials after load cycling and artificial saliva aging.
