Multiple event times in the presence of informative censoring: modeling and analysis by copulas

Motivated by a breast cancer research program, this paper is concerned with the joint survivor function of multiple event times when their observations are subject to informative censoring caused by a terminating event. We formulate the correlation of the multiple event times together with the time to the terminating event by an Archimedean copula to account for the informative censoring. Adapting the widely used two-stage procedure under a copula model, we propose an easy-to-implement pseudo-likelihood based procedure for estimating the model parameters. The approach yields a new estimator for the marginal distribution of a single event time with semicompeting-risks data. We conduct both asymptotics and simulation studies to examine the proposed approach in consistency, efficiency, and robustness. Data from the breast cancer program are employed to illustrate this research.

     

Leader-member exchange as a linking pin in the idiosyncratic deals - Performance relationship in workgroups

In the current investigation, idiosyncratic deals (i-deals; individualized work arrangements) are modeled as differentiated resources that shape leader-member exchange (LMX) relationships in workgroups. We integrate literature on leader-member exchange (LMX) with research on i-deals to argue that employee evaluations of i-deals received from the grantor –typically the leader- enhance employee perceptions of LMX, which in turn become instrumental in generating positive performance outcomes. Furthermore, because workgroup characteristics have potential implications on the relationship between a deal grantor and the deal recipient, drawing upon social identity theory of leadership, we reason that the i-deals-LMX relationship is affected by the overall value congruence among the group members. Cross-level moderated mediation analyses on multi source data obtained from 289 employees nested in 60 workgroups showed that the mediational role of LMX in the i-deals to performance outcomes relationship was weaker in high value congruence groups.     

从意识形态和诗学看《道德经》的英译

《道德经》是道家创始人老子的经典之作,语言凝练简洁,意义丰富,哲理深厚。勒菲弗尔指出翻译是处于意识形态和诗学控制之下对源文的改写。赞助人影响意识形态,而专业人士更加关注诗学。本文主要从意识形态和诗学角度解读《道德经》的英译,分析意识形态和诗学对《道德经》翻译的影响。     

Tests for time series of counts based on the probability-generating function

We propose testing procedures for the hypothesis that a given set of discrete observations may be formulated as a particular time series of counts with a specific conditional law. The new test statistics incorporate the empirical probability-generating function computed from the observations. Special emphasis is given to the popular models of integer autoregression and Poisson autoregression. The asymptotic properties of the proposed test statistics are studied under the null hypothesis as well as under alternatives. A Monte Carlo power study on bootstrap versions of the new methods is included as well as real-data examples.

充分利用土地资源推进县域经济发展

土地资源是人类一切活动的载体,是发展县域经济的基石,是推进县域经济发展的动力.发展县域经济既是贯彻十六大精神的战略要求,又是县域经济发展的客观需求,更是全面建设小康社会的重要举措.因此,必须紧紧抓住充分利用土地资源这个纲,才能有效地推进县域经济尽快进入高速发展的快车道.怎样充分利用土地资源,发展县域经济,本文提出几点探讨性意见.     

德国功能派翻译理论述评

功能派翻译理论是20世纪70年代德国学者提出的翻译理论.主要理论有赖斯的文本类型和语言功能理论,曼塔利的翻译行为理论,威密尔的目的论和诺德的功能加忠诚理论,其核心是翻译目的或译文功能.该理论体系以目的为总则,把翻译放在行为理论和跨文化交际理论的框架中,为西方翻译理论界开辟了一条新的研究道路,它对中国译学的理论研究具有很高的参考和借鉴价值.
