在礼教与世俗间徘徊的市民代言人——由明代士人隐居方式的变化来看近代审美文化发展的趋势

晚明士人隐居于市井时与市民大量接触,使士人能够体察市民的内心情感,不自觉地成为其代言人,从而开始亲近市民文化,自觉不自觉地受市民风情影响,创作出符合市民口味的文学作品。但因他们长期受封建儒家正统文化的影响,所以其行为与其作品中的形象通常又是矛盾的。     

论苏洵的“人情”观及苏、王关系

苏洵<辨奸论>的真伪问题,一直是学界争议的话题.此前的研究,多从版本和史实考订的角度切入,取得了很大进展,但尚难说得以圆满解决.本文试以考察苏洵的"人情"观为重点,观照决定苏、王关系的深刻思想分歧,有些疑难似更容易理解.     

试论钱玄同对顾颉刚的学术影响

钱玄同、顾颉刚均是“古史辨派”的领军人物,而钱氏曾在基本精神和具体主张上给予顾氏精心指导。他不仅一再鼓励顾氏“疑古辨伪”,并启发顾氏从“辨伪书”拓展到“辨伪事”,从“辨伪子”、“辨伪史”发展到“辨伪经”,而且不断号召顾氏打破“今古文”的壁垒。此外,他还从许多方面丰富了顾氏的“古史辨”学说。从这个意义上可以说,钱玄同是“古史辨派”的灵魂人物。     

Not just hot air: normative codes of conduct induce cooperative behavior

The shirking incentives arising within team production are in general counteracted by monitoring and sanctioning. However, these mechanisms are usually associated with high monitoring costs and cannot be applied to all parts of the production process. In a laboratory experiment we analyze the impact of less costly elements of organizational structure, such as normative codes of conduct and screening tests, on team production efficiency. We find that more allusions to a firm context lead to higher contributions. In particular, codes of conduct significantly increase cooperation and at the same time reduce free-riding behavior. Our study provides empirical evidence that normative codes of conduct are an effective means of increasing team production efficiency.

Proportional hazards model for competing risks data with missing cause of failure

We consider the semiparametric proportional hazards model for the cause-specific hazard function in analysis of competing risks data with missing cause of failure. The inverse probability weighted equation and augmented inverse probability weighted equation are proposed for estimating the regression parameters in the model, and their theoretical properties are established for inference. Simulation studies demonstrate that the augmented inverse probability weighted estimator is doubly robust and the proposed method is appropriate for practical use. The simulations also compare the proposed estimators with the multiple imputation estimator of Lu and Tsiatis (2001). The application of the proposed method is illustrated using data from a bone marrow transplant study.     

论《尚书·尧典》之生成及其文体功能

最初的“典”体生成于殷人的贡典制度,主要是书写对祖先神灵的祝告之辞和先王先妣的祀谱和庙号。周人将礼乐法度上升到了“典”的神圣地位,并将先王先公有教益和借鉴意义的话语也称之为“典”。而《尧典》是春秋时人出于制度的焦虑,为王者未来的实践行为建构的一部理想性的行政法典,体现出了迥异于商周其它“典”体的叙事性文体特征。     

Defining equations for two-level factorial designs

Defining equations are introduced in the context of two-level factorial designs and they are shown to provide a concise specification of both regular and nonregular designs. The equations are used to find orthogonal arrays of high strength and some optimal designs. The latter optimal designs are formed in a new way by augmenting notional orthogonal arrays which are allowed to have some runs with a negative number of replicates before augmentation. Defining equations are also shown to be useful when the factorial design is blocked.     

关于因明“指误”的几点商榷

黄志强在《"因明研究"指误》《评因明研究中的几个误区》二文中对因明研究中的七处"指误",混淆了属、种概念与属性概念、具体概念,对陈那因明的同、异品、因三相、九句因的涵义理解有误,对三支因明中的推理性质、推理规则等的看法也存在问题,有不少是黄文的自误。     

Reference priors for constrained rate models of count data

We derive reference priors for constrained rate models of count data using the sequential algorithm of Berger and Bernardo (1992b). The event counts for various groups of subjects are modeled as discrete random variables (Poisson, binomial, or negative binomial) with group specific rates. We consider situations in which the groups can be completely ordered according to one covariate. The priors enforce monotonicity (or monotonicity and convexity) of the rates with respect to the ordering. We use the priors to model a data set on mortality rates for men in different age groups assuming that the mortality rates increase with respect to age. We also consider the situation in which the parameter space is augmented to include rates corresponding to unobserved age groups, and the case of a random upper bound on the mortality rates. In addition, we provide an evaluation of the out-of-sample predictive performance of the proposed methods.
