Bayesian prediction of waiting times in stochastic models

The authors show how saddlepoint techniques lead to highly accurate approximations for Bayesian predictive densities and cumulative distribution functions in stochastic model settings where the prior is tractable, but not necessarily the likelihood or the predictand distribution. They consider more specifically models involving predictions associated with waiting times for semi‐Markov processes whose distributions are indexed by an unknown parameter θ. Bayesian prediction for such processes when they are not stationary is also addressed and the inverse‐Gaussian based saddlepoint approximation of Wood, Booth & Butler (1993) is shown to accurately deal with the nonstationarity whereas the normal‐based Lugannani & Rice (1980) approximation cannot, Their methods are illustrated by predicting various waiting times associated with M/M/q and M/G/1 queues. They also discuss modifications to the matrix renewal theory needed for computing the moment generating functions that are used in the saddlepoint methods.     

北魏、北周、唐时期追祖李陵现象述论——以"拓跋鲜卑系李陵之后"为中心

本文通过考述北魏、北周、唐时期出现的诸多追祖李陵的现象,以"拓跋鲜卑系李陵之后"为讨论中心,从民族融合与文化整合的视角出发,来重新梳理和解析此类深为学界所质疑的追祖现象.本文还结合时代背景,将李陵视为一种胡汉杂糅的文化象征符号,探讨了其在北方游牧人与汉地农耕民接触与交往中所扮演的角色.

论魏晋南朝的忠孝实践——以阳翟褚氏为例

忠孝取舍孰先孰后在魏晋南朝时期有一个演变的过程,弃忠从孝是当时社会的趋势和需要。阳翟褚氏在这一时期屡屡背信弃义违背＂忠＂的道德却又信守家族＂孝＂的传统,是当时忠孝实践观的集中代表。     

A longitudinal study of depressiveness in children in public care

Rajhvajn Bulat L. A longitudinal study of depressiveness in children in public care Int J Soc Welfare 2010: 19: 412–423 © 2009 The Author, Journal compilation © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. The aim of this article is to analyse the challenges involved when making longitudinal observations of depressiveness in children raised in public care. The first measurement comprised 375 children from children's homes and foster families; however, most of the results are based on an analysis of the 139 children who participated in both parts of the research. We used the Child Depression Inventory and the anxiety/depression subscales of Youth Self Report and Child Behaviour Checklist as measures of depressiveness. The comparison of results from the first and second measurements showed that depressiveness in children in public care decreased over time. Children who grew up in children homes were, in the first measurement, more depressed than those living in foster families, but after five years that difference had disappeared. Furthermore, decrease in depressiveness is predominantly associated with less frequent delinquent, aggressive or hyperactive behaviour, less withdrawal and better control over uncomfortable emotions.
