一类积微分方程自由边界问题解的误差估计

讨论带跳扩散模型下美式期权价格及最佳实施边界当执行日期趋于无穷大时的误差估计。在相应的基本假设下,美式期权的定价模型是一个抛物积微分方程自由边界问题,而永久美式期权的定价模型是一个积微分方程自由边界问题。利用抛物型偏微分方程的极值原理,得到了带跳扩散模型下美式期权价格及最佳实施边界的误差估计。

Learning,literacy and identity: ‘I don’t think I’m a failure any more’

The impact of participation in adult literacy programmes on learners’ identities is examined through an interrogation of their past and current experiences and the assessment of the effect of particular pedagogies. The findings show how learners’ positive experiences in their programmes had caused them to re-evaluate their previous understandings and enabled the construction of new identities as people that are able to learn. These changes had come about through the challenging of negative discourses, the creation of new figured worlds and imagined futures, and the use of a learning curriculum where learners’ experiences were utilized as positive resources.

Young people’s and parent’s perceptions of managed moves

The current research aimed to increase understanding of the experiences of young people and their parents of managed moves, what contributed to success and the nature of the challenges experienced. The study was conducted in one English Local Authority, where five young people and their parents were interviewed. Five superordinate themes emerged from the interviews, relating to: the initial process (people, trail period, managed moves as a positive solution); the reasons for the move (bullying/social isolation, breakdown in relationships with staff); conceptions of success (happiness, improved self-perceptions, learning and progress), factors contributing to success (fresh start/clean slate; home–school communication; pastoral support, school suitability) and problems arising (moving a problem, narratives around young people, timing and family stress). The findings are discussed in relation to implications for practice.
