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。

A Survey of William Faulkner''''s Novels'''' Proposition of Endurance

人类的苦忍能力(humanendurance)和终究战胜苦难的思想,是威廉福克纳(WilliamFaulkner)对人类命运的概括。在他看来,人类存在虽然已有千百万年历史,但仍然时刻在为自身的生存殚精竭虑,流血流汗,他作品中的人物都在苦忍(endure)。本文试图通过对苦忍命题具体表现形式的分析探讨该命题的意义及其影响力。     

殖民地时期至镀金时代美国个人主义的发展

作为一种体现资产阶级民主自由思想的价值观念,个人主义在美国有一个发展变化过程。在殖民地时期,北美并没有明显的个人主义倾向。独立战争胜利之后,个人主义倾向在美国得到了相应地发展,但在此后至内战前,它还主要局限于政治范围内。内战结束后,美国的政治经济状况发生了深刻的变化,美国的个人主义突破了政治范围,进而发展到经济上的个人主义。这个过程反映了美国社会历史发展进程。

课堂教学目标的确定——基于美国中小学教材的考察

不同的学派存在不同的关于教育目标的理论研究,其中布卢姆的教育目标分类及其修订版对教育目标的实践行为具有深远的影响。美国教材编写者在制订教学目标时,认真研究教育目标分类学的内容,结合学生和学科特点,使用比较标准的目标动词。美国教材中关于教学目标的叙述,既有目标动词+内容方式,也有问题方式和叙述方式,这对于我国中小学教学目标的设计具有借鉴意义。

Development and Implementation of the Inaugural Anatomy Education Research Institute (AERI 2017)

Education research is increasingly being recognized as a legitimate route for faculty development in universities. However, many anatomy faculty lack the appropriate training and access to experienced mentors who can help them develop their own education research projects. Inspired by the American Physiological Society’s Institute for Teaching and Learning, the coauthors proposed and developed the inaugural Anatomy Education Research Institute (AERI 2017). Funded by an American Association of Anatomists Innovations grant, the five-day institute was held in Bloomington, Indiana in July 2017. The coauthors spent two years preparing the conference schedule, inviting speakers who could discuss education research topics and mentor applicants, reviewing applications, developing assessment instruments for the institute, and hosting the institute. A total of 62 registered participants (applicants and invited speakers) attended AERI 2017. Through a series of presentations and workshops, participants were introduced to many aspects of education research and the Scholarship of Teaching and Learning, including developing rigorous education research questions, determining appropriate methods to assess these questions, and searching the education research literature. Each day also included regular time devoted to work on their own education research project with help from more experienced mentors. Throughout the conference, participants were encouraged to post information on Twitter, using the hashtag #AERI2017. Participants had strong positive impressions of the conference and strongly requested future AERI conferences be held. Follow-up analyses will assess the institute in alignment with Kirkpatrick’s Four Levels of Evaluation Model, though preliminary evaluation indicates AERI 2017 met the original aims of the proposal.
