《红旗谱》研究五十年述评

五十年来的《红旗谱》研究曾掀起三次研究高潮。从关注作品的时代背景、主题、人物形象、认识价值到第二次研究高潮中对其艺术风格、版本、情节构成的深层探讨,再到第三次研究高潮中叙事学角度的分析、文化、美学领域的拓展,《红旗谱》的研究由单一的文本阐释走向了多方位、深向度的交叉学科研究。     

Inter‐professional working in child protection with families with long‐term and complex needs

Within the United Kingdom there is growing awareness of the need to identify and support the small number of children who are living in families experiencing multiple problems. Research indicates that adverse experiences in childhood can result in poor outcomes in adulthood in terms of lack of employment, poorer physical and mental health and increases in social problems experienced. It is acknowledged that most of these children are known to child welfare professionals and that some are referred to social services, subsequently entering the child protection system. This paper reports research conducted with 28 experienced child welfare professionals. It explores their views about families known to the child protection system with long‐term and complex needs in relation to the characteristics of children and their families; the process of intervention with families; and the effects of organisational arrangements on practice. The research indicates that these families are characterised by the range and depth of the problems experienced by the adults, such as domestic violence, mental health difficulties and substance misuse problems, and the need for professionals to have good inter‐personal skills and access to specialist therapeutic services if families are to be supported to address their problems.

论“转变经济发展方式“的新意蕴

"转变经济发展方式"内涵丰富,立意深远,是我们党在探索和把握我国经济发展规律的基础上提出的重要方针,也是从当前我国经济发展的实际出发提出的重大战略。在实践中,我们只有做到理论与实践、经济增长与经济发展、局部服从全局、眼前利益与长远利益、生产力与生产关系相统一,才能促进国民经济又好又快地发展。     

可持续发展的产业分类理论——立体产业分类理论

本世纪 60年代以来 ,自然资源产业、环保产业、高新技术产业 (包括信息产业 )等新兴产业迅速发展 ,其对可持续发展的促进作用 ,已经为各国经济发展的实践所证明 ,也给产业经济研究提出了现实的问题。传统产业分类理论没有对新兴产业的内涵、归属及其在产业结构中的地位等加以揭示 ,使得建立在传统产业分类理论基础上的产业结构演进理论解释现象、指导经济实践的能力减弱。作者在深入分析传统产业分类理论的局限的基础上 ,提出可持续发展的产业分类理论     

Program Evaluation and Causal Inference With High‐Dimensional Data

In this paper, we provide efficient estimators and honest confidence bands for a variety of treatment effects including local average (LATE) and local quantile treatment effects (LQTE) in data‐rich environments. We can handle very many control variables, endogenous receipt of treatment, heterogeneous treatment effects, and function‐valued outcomes. Our framework covers the special case of exogenous receipt of treatment, either conditional on controls or unconditionally as in randomized control trials. In the latter case, our approach produces efficient estimators and honest bands for (functional) average treatment effects (ATE) and quantile treatment effects (QTE). To make informative inference possible, we assume that key reduced‐form predictive relationships are approximately sparse. This assumption allows the use of regularization and selection methods to estimate those relations, and we provide methods for post‐regularization and post‐selection inference that are uniformly valid (honest) across a wide range of models. We show that a key ingredient enabling honest inference is the use of orthogonal or doubly robust moment conditions in estimating certain reduced‐form functional parameters. We illustrate the use of the proposed methods with an application to estimating the effect of 401(k) eligibility and participation on accumulated assets. The results on program evaluation are obtained as a consequence of more general results on honest inference in a general moment‐condition framework, which arises from structural equation models in econometrics. Here, too, the crucial ingredient is the use of orthogonal moment conditions, which can be constructed from the initial moment conditions. We provide results on honest inference for (function‐valued) parameters within this general framework where any high‐quality, machine learning methods (e.g., boosted trees, deep neural networks, random forest, and their aggregated and hybrid versions) can be used to learn the nonparametric/high‐dimensional components of the model. These include a number of supporting auxiliary results that are of major independent interest: namely, we (1) prove uniform validity of a multiplier bootstrap, (2) offer a uniformly valid functional delta method, and (3) provide results for sparsity‐based estimation of regression functions for function‐valued outcomes.     

Non‐parametric Threshold Estimation for Models with Stochastic Diffusion Coefficient and Jumps

Abstract. We consider a stochastic process driven by diffusions and jumps. Given a discrete record of observations, we devise a technique for identifying the times when jumps larger than a suitably defined threshold occurred. This allows us to determine a consistent non‐parametric estimator of the integrated volatility when the infinite activity jump component is Lévy. Jump size estimation and central limit results are proved in the case of finite activity jumps. Some simulations illustrate the applicability of the methodology in finite samples and its superiority on the multipower variations especially when it is not possible to use high frequency data.     

坚持依法行政抓紧抓好计划生育工作

依法行政是抓紧抓好计划生育工作的前提 ,也是维护法律权威和保护计生干部的需要。缺乏现代法律意识、缺乏有效的监督机制、缺乏解决基层行政执法难题的有效办法、缺乏对基层计生工作公正评价的能力是计生工作中制约依法行政的因素。强化全民法律意识 ,建立激励机制、内、外部检查机制及孕前管理机制等综合措施 ,以保证计划生育依法行政

春秋金文量词考析

在对出土古文字的研究中,历来都是文字字形的研究重于相应词汇的研究。基于《春秋金文语料数据库》,在对现有春秋金文(可识部分)进行穷尽性的调查之后,离析出其中的量词,就其使用状况加以全面观照,并进行分类分析,归纳出其语法功能与语义特征,以显示量词这一词类在春秋时期的发展脉络,以及在先秦出土文字词汇发展中的重要地位。
