试论网络传播与记者传播方式的调适

:作为第四大传播媒介 ,互联网以其交互性、信息量大、传播权利平等 ,将传统媒体整合为一等巨大优势 ,对传统媒体 (广播、电视、报纸等 )构成威胁。但网络时代的到来并不意味着传统媒体记者“下岗时代的来临”,只要记者面对新兴媒体作传播方式的调适 ,即转换传播观念、重新认识受众、提高质量意识、学会数字化生存和“超链接”文本写作等 ,记者仍然是网络新闻传播的主力军     

广州建设国际大都市的产业调适研究

产业结构与世界大都市整合是建设国际大都市最为重要的一个方面。本文分析了广州产业结构调适的必要性，认为广州与国际大都市相比较有明显的不足，因此必须从产业结构化、产业创新、产业成长的环境等方面着手，以产业发展的市场为导向，利用世界产业结构调整的机遇，迅速整合世界大都市产业发展的趋势，建立高度外向型、国际化、创新型协调发展的城市产业结构关系。     

民族地区特殊的社会关系及其战略调整

一定的社会是由特定的社会关系建立起来的，它既是社会个体和群众赖以生存和发展的基本条件，又是人们社会行动的基本限定要素。民族地区的社会关系既有一般性又有特殊性，民族关系实质上是一种特殊的社会关系，调整和构建和谐的社会关系对促进民族地区的发展和繁荣具有重要意义。     

Understanding the 2001 UK census migration and commuting data: the effect of small cell adjustment and problems of comparison with 1991

Summary.  Origin–destination statistics have been produced from the last three UK censuses. The paper describes what is new about the 2001 census interaction data on migration and commuting, considers the disclosure control methods that were applied to cells containing small values and demonstrates the problems that are associated with making comparisons with 1991 data. The effect of small cell adjustment procedures on the interaction data sets is investigated by means of selective analyses at different spatial scales. Some recommendations are made in light of the problems that were manifest in 2001.     

An Asymptotic Analysis of the Logrank Test

Asymptotic expansions for the null distribution of the logrank statistic and its distribution under local proportional hazards alternatives are developed in the case of iid observations. The results, which are derived from the work of Gu (1992) and Taniguchi (1992), are easy to interpret, and provide some theoretical justification for many behavioral characteristics of the logrank test that have been previously observed in simulation studies. We focus primarily upon (i) the inadequacy of the usual normal approximation under treatment group imbalance; and, (ii) the effects of treatment group imbalance on power and sample size calculations. A simple transformation of the logrank statistic is also derived based on results in Konishi (1991) and is found to substantially improve the standard normal approximation to its distribution under the null hypothesis of no survival difference when there is treatment group imbalance. This revised version was published online in July 2006 with corrections to the Cover Date.     

Bias Reduction through First-order Mean Correction, Bootstrapping and Recursive Mean Adjustment

Standard methods of estimation for autoregressive models are known to be biased in finite samples, which has implications for estimation, hypothesis testing, confidence interval construction and forecasting. Three methods of bias reduction are considered here: first-order bias correction, FOBC, where the total bias is approximated by the O(T^-1) bias; bootstrapping; and recursive mean adjustment, RMA. In addition, we show how first-order bias correction is related to linear bias correction. The practically important case where the AR model includes an unknown linear trend is considered in detail. The fidelity of nominal to actual coverage of confidence intervals is also assessed. A simulation study covers the AR(1) model and a number of extensions based on the empirical AR(p) models fitted by Nelson & Plosser (1982). Overall, which method dominates depends on the criterion adopted: bootstrapping tends to be the best at reducing bias, recursive mean adjustment is best at reducing mean squared error, whilst FOBC does particularly well in maintaining the fidelity of confidence intervals.     

农民工大病统筹医疗保险政策分析——以济南市为例

许多地方政府将农民工医疗保险问题提上议程,并出台了不尽相同的医疗保险政策.目前农民工在城市可参加的医疗保险主要有三种:城镇职工基本医疗保险、综合社会保险以及大病统筹医疗保险.本文主要针对实施相对广泛的农民工大病统筹医疗保险政策进行分析,具体以济南市农民工医疗保险政策为例,并在政策分析的基础上提出政策调整的建议.     

论城市土地资源的集约化配置

城市土地资源的集约化配置应坚持的原则是:增加土地的有效供给;实现土地资产综合效益最大化;保持土地资源的永续利用。城市土地的集约化配置需要政府调控与市场机制的结合:政府的主导作用是制定土地利用规划,建立城市土地储备制度以解决市场失灵问题,市场机制的基础作用在于形成利润最大化的土地利用空间。城市土地资源的集约化配置的主要路径是推进城市用地置换,改造旧城区和土地的立体化使用。

“Separation Guilt” in Women Who Initiate Divorce

This paper explores the “separation guilt” of women who initiate divorce. The paper argues that the gender-specific processes of separation individuation and socialization that women undergo in childhood make them vulnerable to similar guilt feelings when they initiate divorce, only towards the husband they are leaving. It further argues that these feelings may impair their post-divorce adjustment. The paper illustrates these points with two case studies, one showing how the woman’s separation guilt thwarted the development of new intimacy, the other showing how it impaired her maternal functioning. Recommendations are made for treatment and research. Nehami Baum Ph.D., is a lecturer at the School of Social Work at Bar Ilan University.
