碎片化的民间文化元素在《聊斋志异》中的运用

对民间文化元素的吸收和运用是《聊斋志异》的突出特点。这种吸收既包含整篇故事结构及主题的类型化,也有作为小说构成成分的碎片化应用。对《聊斋志异》中"碎片化"的民间文化元素,从"民间故事母题"和"民间谣谚谜联"两个方面进行探析,进一步揭示民间文化与文学创作之间的关系,以增进研究者对民间文学母题在文化传统影响下流变发展脉络的认识。     

浅谈编写适应地方特色的新型教材的重要性

目前可以选用的化工基础教材对于新建地方本科院校的学生来讲理论推导太多、例题太少,且与当地工业项目不匹配,不利于学生的学和老师的教。为了进一步提高教学质量,在陕西八所地方院校的共同努力下,合作编写适应地方特色的《化工基础》教材。本次教材改革对于提高非化工专业学生的工程意识和拓宽就业面具有重要的意义。

论苗族歌鼟的艺术美

苗族歌鼟是湖南湘西南部靖州苗族侗族自治县锹里一带流传的多声部民歌,其旋律优美,声部和谐,唱腔独特,具有自然朴实的民族特色,给人以美的享受。这种艺术美渗透于苗族歌鼟的各个构成元素,非常注重旋律、节奏、和声、调式的美感;歌词体现出苗民们的内在美;唱腔充分发挥出演唱的声韵美;语言更是彰显了民族之本色。这些艺术美的元素综合在一起,使苗族歌鼟成为一种美的化身。     

Collective versus Individual Effects in Survival Analysis of Multiple Failures

In survival analysis, we sometimes encounter data with multiple censored outcomes. Under certain scenarios, partial or even all covariates have ‘similar’ relative risks on the multiple outcomes in the Cox regression analysis. The similarity in covariate effects can be quantified using the proportionality of regression coefficients. Identifying the proportionality structure, or equivalently whether covariates have individual or collective effects, may have important scientific implications. In addition, it can lead to a smaller set of unknown parameters, which in turn results in more accurate estimation. In this article, we develop a novel approach for identifying the proportionality structure. Simulation shows the satisfactory performance of the proposed approach and its advantage over estimation under no assumed structure. We analyse three datasets to demonstrate the practical application of the proposed approach.     

A Proportional Hazards Regression Model for the Subdistribution with Covariates‐adjusted Censoring Weight for Competing Risks Data

With competing risks data, one often needs to assess the treatment and covariate effects on the cumulative incidence function. Fine and Gray proposed a proportional hazards regression model for the subdistribution of a competing risk with the assumption that the censoring distribution and the covariates are independent. Covariate‐dependent censoring sometimes occurs in medical studies. In this paper, we study the proportional hazards regression model for the subdistribution of a competing risk with proper adjustments for covariate‐dependent censoring. We consider a covariate‐adjusted weight function by fitting the Cox model for the censoring distribution and using the predictive probability for each individual. Our simulation study shows that the covariate‐adjusted weight estimator is basically unbiased when the censoring time depends on the covariates, and the covariate‐adjusted weight approach works well for the variance estimator as well. We illustrate our methods with bone marrow transplant data from the Center for International Blood and Marrow Transplant Research. Here, cancer relapse and death in complete remission are two competing risks.
