从“宣传工作”到“宣传文化”——传播学视野中的宣传刍议

本文从宣传效果、宣传功能的角度分析我国宣传工作经历的四个阶段，指出党的十七大报告中提出的“建设社会主义核心价值体系，建设和谐文化”，“激发全民族文化创造活力，提高国家文化软实力”正将我国宣传工作引入新阶段，也是对我国宣传文化系统在国家软实力构建过程中应承担文化传播功能的全新工作要求。

Some results on optimality in models with heteroscedastic errors from partial optimum designs

This paper studies optimum designs for linear models when the errors are heteroscedastic. Sufficient conditions are given in order to obtainD-, A- andE-optimum designs for a complete regression model from partial optimum designs for some sub-parameters. A result about optimality for a complete model from the optimality for the submodels is included. Supported by Junta de Andalucía, research group FQM244.     

A “brer rabbit” case for reverse mandated benefits

Reverse mandated benefits is a government-mandated policy that requires employees to provide their employers with benefits that workers would not provide otherwise. Of course, only those benefits would be mandated that are worth more to employers than they cost, as determined by political authorities. My case for such a policy argues that it is at least as sensible as policies mandating that employers provide benefits to their employees that would not be provided otherwise.     

Intertemporal choice under timing risk: An experimental approach

This paper investigates how individuals evaluate delayed outcomes with risky realization times. Under the discounted expected utility (DEU) model, such evaluations depend only on intertemporal preferences. We obtain several testable hypotheses using the DEU model as a benchmark and test these hypotheses in three experiments. In general, our results show that the DEU model is a poor predictor of intertemporal choice behavior under timing risk. We found that individuals are averse to timing risk and that they evaluate timing lotteries in a rank-dependent fashion. The main driver of timing risk aversion is nothing but probabilistic risk aversion that stems from the nonlinear treatment of probabilities.     

二元序列优化的二种快速算法

基于二相编码雷达对大压缩比信号的要求,提出了一种比直接算法平均提高效率0.5P(P 为序列长度)的快速数字优化方法。作为这种快速算法的实际应用,还对 P=255的二相编码脉冲压缩信号进行了优化。     

人民币升值能解决我国国际收支不平衡问题吗

由于中国国内产出的增加远远大于国内吸收,因而存在巨额规模储蓄盈余并表现为持续且庞大的经常项目顺差。故国际收支常处于不平衡状态,人民币也面临越来越大的升值压力。本文主要运用国际收支的吸收分析法和货币分析法并结合凯恩斯乘数过程,试图分析人民币升值能否以及如何改善我国的国际收支并考察求得我国国际收支平衡的必要以及充分条件。     

如何与不胜任工作的员工解除合同

笔者日前在听一位国内资深人力资源管理专家的讲座时,该专家提出了我国目前人力资源管理的主要问题之一是"头重脚轻".人力资源管理部门在招聘员工的时候,严格把关,层层筛选,各类招聘工具花样繁多.可是一旦员工招进来了,人力资源管理部门却管得不够了,于是员工的效能慢慢降低.要保持企业的活力就必须加强对企业淘汰制度的建设,作到有进有出,能进能出,以实现企业内部的有机循环.
