内容简介
This book is a second edition of the book of the same title by the first authorwhich was published in 2000. The subject of ruin probabilities and related top- ics has since then undergone a considerable development, not to say boom. This much expanded and revised second edition aims at covering a substantial part of these developments as well as the classical topics.
R,isk theory in general and ruin probabilities in particular are traditionally considered as part of insurance mathematics, and has been an active area of research from the days of Lundberg all the way up to today. One reason for writing tlus book is a feeling that the area has in recent years achieved a con-siderable mathematical maturity, which has in particular removed one of the standard criticisms of the area, namely that it can only say something about very simple models and questions. Although in insurance practice, usually sim- pler (and coarser) risk measures like Value-at-Risk are used, it is widely believed that the thinking advocated by ruin theory is still important for modern risk management. For instance, in times of market-consistent valuation principles, the role of the time diversification effect of insurance portfolios, which is one of the core elements of ruin theory, should not be forgotten. In addition, ruin the- ory has fruitful methodological links and applications to other fields of applied probability, like queueing theory and mathematical finance (pricing of barrier options, credit products etc.). Apart from these remarks, we have deliberately stayed away from discussing the practical relevance of the theory; if the formu- lations occasionally give a different impression, it is not by intention. Thus, the book is basically mathematical in its flavor.

真是单纯而直接啊,然后我爸就帮我报了名,交了50块钱报名费,而且还给我50块钱揣兜里。我是冲着爸爸的奖励来的,但是没想到上去之后非常紧张,那天唱的是“小镇姑娘)):“不明白,为什么我不能放得开……”还是带着动作的。初生牛犊不怕虎,所以随便后来他们才告诉我,所有评委都通过。完第一轮之后,我跟爸爸说:“如果我又进的话,怎么办?”我爸干脆地说:“言而有信,200。”我当时就想,为了200,我一定会进前60的。

好像在十三四岁这种年纪,每个男孩子都会近乎痴迷地开始玩游戏吧。除了自己喜欢玩之外,如果不玩游戏,根本就没有办法跟小伙伴交流啊,因为大家都在玩,聊的也是游戏。在我印象里,哪怕是那些“学霸”,好像也都在私下里玩。当然了,无一例外,大人们都会觉得打游戏是很不好的,简直是坏孩子的标签和学习进步的大敌。所以啊,要想让他们爽快地给钱去打游戏,简直是白日做梦。有一天晚上,我爸在电视上看到这个消息。等我打完球回到家,一身臭汗地坐在沙发上,我爸超级淡定地来到我对面坐下,然后说,你去《明星学院》参加比赛吧,进第一轮我给你50,进第二轮我给你200,要是你运气好能进到第三轮的话,我就给你500……哇,500块!简直就是一笔巨款!我当时眼睛就亮起来了,想了想,真是不错啊,就去转一圈吧,唱歌简简单单啦,挣的钱正好可以买向往已久的游戏装备。为了50块钱拼了!

从初选到进入前60,一路过关都很轻松,我慢慢地就不紧张了。但从60进24的时候,反而妈妈开始紧张,但她很相信我,到处说,我的儿子一定会进决赛的。当时周围的人都觉得她疯了吧。

参加《明星学院》在我的人生里是一个非常重要的关键点。那时我十三四岁,什么也不懂,学了一堆东西,都不喜欢,爱打游戏,却又总是被家里人说这是不学好。我不懂自己想要什么,不懂自己应该做什么,更想都没想过什么人生和未来了。去参加比赛的原因非常简单——打游戏需要50块钱。

比赛的时候我十三岁,是年龄最小的一个。在比赛中,不管是一起参加比赛的哥哥姐姐,还是节目组的工作人员,都把我当最小的弟弟看待。他们教我选歌,指导我唱歌,帮我排舞,告诉我舞台应该怎么站,上台应该怎么做。当时我就觉得这么一群人,都是带着光的。后来懂事了才知道,那是一种因为对音乐的热爱而发出的光芒。
