A shared parameter model of longitudinal measurements and survival time with heterogeneous random-effects distribution

Typical joint modeling of longitudinal measurements and time to event data assumes that two models share a common set of random effects with a normal distribution assumption. But, sometimes the underlying population that the sample is extracted from is a heterogeneous population and detecting homogeneous subsamples of it is an important scientific question. In this paper, a finite mixture of normal distributions for the shared random effects is proposed for considering the heterogeneity in the population. For detecting whether the unobserved heterogeneity exits or not, we use a simple graphical exploratory diagnostic tool proposed by Verbeke and Molenberghs [34] to assess whether the traditional normality assumption for the random effects in the mixed model is adequate. In the joint modeling setting, in the case of evidence against normality (homogeneity), a finite mixture of normals is used for the shared random-effects distribution. A Bayesian MCMC procedure is developed for parameter estimation and inference. The methodology is illustrated using some simulation studies. Also, the proposed approach is used for analyzing a real HIV data set, using the heterogeneous joint model for this data set, the individuals are classified into two groups: a group with high risk and a group with moderate risk.     

民族矛盾与文化冲突的二重变奏——由遵义教案引发的思考

近代中国,教案是十分突出的社会政治和文化现象.基督教在传播中呈现的侵略性、强权性,激化了中华民族与资本帝国主义之间的矛盾,成为近代教案频发的根本原因.基督教实施强制性的文化移植,挑起中西礼俗冲突,则是民族矛盾的延伸和深入,构成民教冲突的内蕴.中国人民的反洋教斗争,在政治上具有无可辩驳的正义性,并反映了民众对于本土文化的珍惜与捍卫.但是,对于近代教案所凸显的文化保守主义的价值取向,也必须予以正视.     

Time-varying coefficient cumulative gap time models for intensive longitudinal ecological momentary assessment data with missingness

Ecological momentary assessment (EMA) studies investigate intensive repeated observations of the current behavior and experiences of subjects in real time. In particular, such studies aim to minimize recall bias and maximize ecological validity, thereby strengthening the investigation and inference of microprocesses that influence behavior in real-world contexts by gathering intensive information on the temporal patterning of behavior of study subjects. Throughout this paper, we focus on the data analysis of an EMA study that examined behavior of intermittent smokers (ITS). Specifically, we sought to explore the pattern of clustered smoking behavior of ITS, or smoking ‘bouts’, as well as the covariates that predict such smoking behavior. To do this, in this paper we introduce a framework for characterizing the temporal behavior of ITS via the functions of event gap time to distinguish the smoking bouts. We used the time-varying coefficient models for the cumulative log gap time and to characterize the temporal patterns of smoking behavior, while simultaneously adjusting for behavioral covariates, and incorporated the inverse probability weighting into the models to accommodate missing data. Simulation studies showed that irrespective of whether missing by design or missing at random, the model was able to reliably determine prespecified time-varying functional forms of a given covariate coefficient, provided the the within-subject level was small.     

羊群效应与内幕信息的揭示分析

本文用金融市场微观结构模型的序贯交易框架分析了证券市场上的多维不确定性怎样引起投资者的羊群交易行为。结论表明当市场上存在事件不确定和信息精度不确定时,投资者之间可能发生羊群行为,这种行为会导致内幕信息在一段时间内得不到有效揭示。做市商在发生羊群效应期间虽然只能判断出事件的存在性,而无法学习到内幕信息的好坏和精度,但他仍会继续调整资产的价格并最终结束羊群效应。     

企业产品伤害危机响应策略对股票市场的影响

以2012年国内"毒胶囊"事件中被通报胶囊产品铬超标的5家医药上市企业为例,运用事件研究法,通过多案例分析企业产品伤害危机响应策略对市场反应的影响。结果表明:整体而言,企业产品伤害危机将引起股票市场的负向反应。在减少股市损失方面,最优的是积极回应策略;企业采取辩解或被动回应策略对股票市场的影响并无显著差异;当企业采取含糊回应方式时,股市遭受的损失最大。     

The UEFA European Football Championship 2012 and pop nationalism in Poland: between confirmation and contestation

Poland and Ukraine jointly hosted the European Football Championship in 2012. The Polish media and government portrayed Euro 2012 as the culmination of the post-communist transformation that started in 1989, a great national celebration and proof that Poland belonged to the family of ‘modern’ nations. Drawing on ethnographic research, we look beyond the official discourse and analyse Euro 2012 ‘from below’ in our paper. We focus on analysing the different meanings attributed to Euro 2012 in Poland in the context of the dominant discourse. Referring to Stuart Hall, we distinguish and analyse three readings of Euro 2012, namely the dominant (‘celebrators’), negotiated (‘indifferentists’, ‘modernisers’) and oppositional (‘radical nationalist’, ‘rebels’) readings.     

Age at Coresidence,Premarital Cohabitation,and Marriage Dissolution: 1985–2009

Does the age at which premarital cohabitors moved in together explain why they have been found to have an increased risk of marital dissolution? Explanations for the increased risk of marriage dissolution among those who marry young center on marital role preparation; for premarital cohabitors, many, if not most, of these roles began at the onset of cohabitation, not marriage. Analyses of the 1995, 2002, and 2006–2010 waves of the National Survey of Family Growth (N = 7,037) revealed that age at coresidence explained a substantial portion of the higher marital dissolution risk of premarital cohabitors. In comparisons standardized by age at coresidence, the difference in risk of marital dissolution between premarital cohabitors and those who married without prior cohabitation (“direct marriers”) was much smaller than in comparisons standardized by age at marriage, and in some models this difference was not significant. Selection into direct marriage and premarital cohabitation was also examined.
