Costs and Rewards of Children: The Effects of Becoming a Parent on Adults' Lives

How do new parents differ from their childless counterparts in social and psychological resources, daily strains, and psychological well‐being? Using a nationally representative panel of 1,933 adults who were childless at the first interview, we compare 6 indicators of adults' lives for those who became parents and those remaining childless several years later, controlling for earlier states. Becoming a parent is both detrimental and rewarding. With the exception of social integration, which is greater for all groups of new parents compared with their childless counterparts, the effects of parental status on adults' lives vary markedly by gender and marital status. Unmarried parents report lower self‐efficacy and higher depression than their childless counterparts. Married mothers' lives are marked by more housework and more marital conflict but less depression than their childless counterparts. Parental status has little influence on the lives of married men.

Valuation of childhood risk reduction: the importance of age, risk preferences, and perspective.

This article explores two problems analysts face in determining how to estimate values for children's health and safety risk reductions. The first addresses the question: Do willingness‐to‐pay estimates for health risk changes differ across children and adults and, if so, how? To answer this question, the article first examines the potential effects of age and risk preferences on willingness to pay. A summary of the literature reporting empirical evidence of differences between willingness to pay for adult health and safety risk reductions and willingness to pay for health and safety risk reductions in children is also provided. The second dimension of the problem is a more fundamental issue: Whose perspective is relevant when valuing children's health effects—society's, children's, adults‐as‐children, or parents'? Each perspective is considered, followed ultimately by the conclusion that adopting a parental perspective through an intrahousehold allocation model seems closest to meeting the needs of the estimation problem at hand. A policy example in which the choice of perspective affects the outcome of a regulatory benefit‐cost analysis rounds out the article and emphasizes the importance of perspective.     

长歌当哭，寓悲于闲——晚唐送人赴任诗情感探微

送人赴任之作,在唐代别离诗中占有相当大比例.盛唐人的这类诗歌,往往忽略了别离之伤情.反之,晚唐却固囿于这一伤情,并将此进一步深化,深化的结果,就是诗歌中闲情的泛滥.这不是偶然的,而是晚唐文人大范围接受佛道思想的必然结果.

There be句型在机器翻译软件中的对比研究

机器翻译虽已取得了很大进展,但仍主要停留在查词功能上,其译文可读性不强,准确性不够。以英语特殊句型Therebe为切入点,着重探讨英汉机器翻译中特殊句型的对应与不对应的调整问题,并以五种英汉全文机器翻译软件作为测试对象,就可以分析发现机器翻译软件在Therebe句型英汉翻译过程中的两点不足:一方面,将there译成地点状语“那里”;另一方面,翻译时不能对地点状语或时间状语进行位置调整,只能机械地逐词顺译。     

论缔约过失责任的赔偿范围

赔偿范围问题在缔约过失责任理论中一直颇有争议。本文基于缔约过失责任概念的基本界定,认为缔约过失责任损害赔偿的基本范围为信赖利益的损失。相应地,为契合缔约过失责任理论的创立初衷和平衡当事人的利益,信赖利益的赔偿范围应包括了间接利益、非财产上损失以及第三人等损失,但应以履行利益为限。     

Statistik für bivariate gemischte Poisson–Prozesse am Beispiel der Kraftfahrthaftpflichtversicherung

Zusammenfassung: In diesem Artikel wird der Weg von einem univariaten gemischten Poisson–Prozess, der in vielen Bereichen zum Z?hlen von Ereignissen benutzt wird, zu einem bivariaten gemischten Poisson–Prozess aufgezeigt. Dazu werden einige Eigenschaften des bivariaten Prozesses angegeben. Im zweiten Teil der Arbeit wird gezeigt, wie mit Hilfe dieses Prozesses der übergang von einem herk?mmlichen Bonus–Malus–System in der Kraftfahrthaftpflichtversicherung zu einem Bonus–Malus–System mit Berücksichtigung der Schadenart beschritten werden kann. Dazu wird zuerst eine Modellprüfung der gegebenen Daten vorgenommen und sodann werden für verschiedene mischende Verteilungen die Verteilungsparameter gesch?tzt und Nettopr?mien angegeben sowie die Prognosegenauigkeit getestet.

Summary: In this paper we show that the model of the bivariate mixed Poisson process arises in a natural way from the univariate mixed Poisson process, which is used in several areas for counting certain events. Furthermore we state some properties of the bivariate process. In the second part of the paper we illustrate how by means of the bivariate mixed Poisson process a bonus–malus system handling different types of accidents can be derived from the classical bonus–malus system in third–party liability insurance. To this end we first check the model on the given data and then estimate distribution parameters and compute net premiums for different mixing distributions as well as test the prediction probabilities.
