生成图式与反思理性——解析布迪厄的知识社会学理论

知识社会学思想是布迪厄社会学理论的有机组成部分,也是理解他的整个社会学研究工作的重要线索。布迪厄借用现象学概念,对知识与社会的关系等问题进行重新诠释,并为当代知识社会学的解释模式注入了新的活力。本文认为,布迪厄对知识社会学理论的贡献主要体现在以下两个方面：第一,借鉴现象学认识论,将人类的思维原则述作“生成图式”或“信念”,用二重性表述替代了认知范畴与社会范畴的二元对立;第二,通过对“实践知识”与“科学（含社会学）知识”遵循的相异逻辑进行说明,探讨了客观真知的生成所倚赖的具体社会条件。     

佛缘万乐岛

上次去桓仁还是七年前。那时,我刚刚参加工作,懵懵懂懂,对一切事物充满好奇七年后,经历了太多的悲欢离合,体味了太多的酸甜苦辣,心态平和淡定了许多。相比于五女山的俊美、大雅河的秀丽,万乐岛的禅意更能吸引现在的我。从五女山的点将台遥望,可以清晰地看到万乐岛酷似古代的"乐"字,万乐岛也因此得名。万乐岛位于桓龙湖中,如果说桓龙湖像一条腾飞的巨龙,那万乐岛就是这条巨龙身上一颗璀璨的明珠。从桓龙湖游艇码头乘快艇,大约10分钟就可以到达万乐岛。登上万乐     

“圣泉第一”说东汤

山是眉峰聚,水是眼波横。是山化育了丹东的峥嵘大气,是水涵养了丹东的隽永秀美。如果单单说起水,丹东,除了有海的浩瀚、湖的深邃、江的灵动、河的洒脱之外,更有泉的汹闰,泉的上善。     

Estimation and inference for generalized semi-varying coefficient models

This paper is concerned with the estimation and inference in generalized semi-varying coefficient models. An orthogonal projection local quasi-likelihood estimation is investigated, which can easily be used to estimate the model parametric and nonparametric parts. Then an empirical likelihood logarithmic approach to construct the confidence regions/intervals of the nonparametric parts is developed. Under some mild conditions, the asymptotic properties of the resulting estimators are studied explicitly, respectively. Some simulation studies are carried out to examine the finite sample performance of the proposed methods. Finally, the methodologies are illustrated by a real data set.     

Feasible algorithm for linear mixed model for massive data

This article studies computation problem in the context of estimating parameters of linear mixed model for massive data. Our algorithms combine the factored spectrally transformed linear mixed model method with a sequential singular value decomposition calculation algorithm. This combination solves the operation limitation of the method and also makes this algorithm feasible to big dataset, especially when the data has a tall and thin design matrix. Our simulation studies show that our algorithms make the calculation of linear mixed model feasible for massive data on ordinary desktop and have same estimating accuracy with the method based on the whole data.     

Quickly variable selection for varying coefficient models with missing response at random

This paper focuses on the variable selections for a varying coefficient models with missing response at random. A procedure is presented by basis function approximations with smooth-threshold estimating equations. Furthermore, the proposed method selects significant variables and estimates coefficients simultaneously avoiding the problem of solving a convex optimization, which reduced the burden of computation. Compared to existing equation based approaches, our procedure is more efficient and quick. With proper choices the regularization parameter, the resulting estimates perform an oracle property. A cross-validation for tuning parameter selection is also proposed, a numerical study confirms the performance of the proposed method.     

Comparisons of several Pareto distributions based on record values

In order to avoid wrong conclusions in any further analysis, it is of importance to conduct a formal comparison for characteristic quantities of the distributions. These characteristic quantities we are familiar with include mean, quantity and reliability function, and so on. In this paper, we consider two tests aiming at the comparisons for function of parameters in Pareto distribution based on record values. They are generalized p-value-based test and parametric bootstrap-based test, respectively. The resulting procedures are easy to compute and are applicable to small samples. A simulation study is conducted to investigate and compare the performance of the proposed tests. A phenomenon we note is that generalized p-value-based test almost uniformly outperforms the parametric bootstrap-based test.

住房价格、土地价格与地方政府行为

本文基于中国35个大中城市2005至2015年的面板数据,通过构建具有“空间依赖”性质的房价地价空间面板联立方程模型,深入研究房价与地价关系、地方政府行为对房价和地价的作用机制以及城际间的相互作用。研究表明,临近城市间的房价相互“模仿”并一同推动地价上涨,房价对地价的影响呈现“模仿促进”的作用特征;各城市通过尽可能抬高本地地价来拉大与临近城市地价水平的差距,进而推高房价,实现“以地生财”。此外,研究还证实地方政府通过“价格途径”和“政策途径”均能对房价进行有效调控,且“价格途径”具有一定的传染性;而“数量途径”和“结构途径”作为地方政府控制地价的有效手段,具有较强的溢出效应。
