Experience ratemaking plays a crucial role in general insurance in determining future premiums of individuals in a portfolio by assessing observed claims from the whole portfolio. This paper investigates this problem in which claims can be modeled by certain parametric family of distributions. The Dirichlet process mixtures are employed to model the distributions of the parameters so as to make two advantages: to produce exact Bayesian experience premiums for a class of premium principles generated from generic error functions and, at the same time, provide robust and flexible ways to avoid possible bias caused by traditionally used priors such as non informative priors or conjugate priors. In this paper, the Bayesian experience ratemaking under Dirichlet process mixture models are investigated and due to the lack of analytical forms of the conditional expectations of the quantities concerned, the Gibbs sampling schemes are designed for the purpose of approximations. 相似文献

《德伯家的苔丝》是英国著名小说家托马斯.哈代的悲剧代表作。透过作品品读作者哈代的悲剧观,这种悲剧观不是让人痛让人哭,而是让人以一种淡淡的忧伤感受悲观,以局外人的淡定感受一种注定如此、必然这样的悲剧生成。哈代通过笔下的人物让读者看到他对待悲剧的态度,直接面对并坦然接受这种结局。 相似文献

针对高职高专院校学生生源的层次差异,英语教学可采用分层教学,即根据学生个体差异,将学生分成不同水平的班组,制订不同的计划、目标和方法进行教学。分层教学能够使更多的学生在各自基础上得到最为有效、合理的发展,使各类学生的潜能都能得到最大程度的开发。分层教学实施过程中,要注意制订科学合理的分层方案,进行科学有效的管理,注重教师教育科研水平的提升。 相似文献

Responding to the call for culturally informed research on autism spectrum (AS) to allow for the provision of appropriate services, this paper qualitatively explores the affective experience of five Korean learners identified with AS and cognitive difficulties by listening to their voices. The learners, supported by the use of visual aids and a choice of their preferred mode of communication, expressed the complexity of their inner experience that encompassed abilities as well as difficulties. The findings highlight the commonalities of experience between Korean and non-Korean individuals with AS, along with some aspects specific to the Korean cultural context. 相似文献

We describe a public good experiment, a type of economic experiment commonly used to examine feelings of prosociality—that is, behaviour which is positive, helpful and intended to promote social acceptance and friendship—and community cohesion, carried out in Rwanda. Contributions in different parts of the country are affected by the local intensity of the 1994 genocide, with more generous contributions being made in areas where violence was greater. This supports earlier research indicating that conflict experience leads to greater prosociality. However, we also find that people who have not, themselves, been targets of violence give lower contributions than people who have. The considerable group‐related and regional differences in social behaviour may have implications for the country's policies to deal with social cohesion. 相似文献

This article examined the theoretical meanings of pension rights and analyzed their effects on women's economic risks in developed countries. First, based on the status of a citizen, worker, parent, and spouse, this study investigated how pension benefits are guaranteed as a citizen regardless of work history, the degree to which women's disadvantageous situations in the labor market and unpaid work are compensated by public pension as workers and parents, and how marital status is treated in the different pension systems. Second, analysis of the effect of pension rights showed that individual rights is a significant factor to prevent economic risks of elderly women. Derived rights did not seem to secure the economic welfare of elderly women, at least in a comparative context. This finding suggested that developing individual rights, rather than derived rights, is the way to guarantee long‐term elderly women's economic welfare. 相似文献

This paper explores the connections between the television show Xena: Warrior Princess, and the myths of lesbian origins which were created by a loose collection of writers known as warrior poets. It argues that the show contains significant components of those myths as imagined by Audre Lorde and Monique Wittig. In particular, both show and myths share the presence of irresponsible gods; ideas of destiny; and women-centredness, which includes parthenogenesis, love, desire, and rivalry between women. The paper suggests that the transformative power of the show comes largely from the erotic connection between women that is at the core of these lesbian origin myths. 相似文献
