Demographic transformation in Poland

The author presents a general review of the demographic transition in Poland from 1750 to the present day. Official data are used to describe the fluctuations in birth and death rates over this period.     

A gold key to initiate a new situation in family planning work]

Because of the popularization of a responsible agricultural production system, the livilihood of peasants has been improving greatly, while the demands and needs of the general public are also increasing at the same time. Still under the influence of the traditional belief of carrying on one's family line and emphasis on having male children, married people prefer to have more childre, and the birth rate is now rising again. In order to solve this new problem, we need to teach the peasants national policies on population, land utilization, and food supply. In order to initiate a new situation in family planning work, we need to control this "gold key" of ideological education and propaganda. The emphasis should be placed on ideological education for cadres at all levels as well as the general public in order that they may understand the Party's strategy. Education on the national strategy should be combined with material interests of the peasants, and reward and punishment in production should also be linked up with that of family planning. Social measures are needed to reduce economic burdens of the peasants, offer better treatment for single-child households, and provide adequate care for old and retired people. Family planning projects should be consolidated and improved. Scientific management, facilities and techniques for birth control, compensation for working personnel in family planning, and other practical problems deserve immediate attention and solution.

Determination of recovery effort for a probabilistic recovery system under various inventory control policies

In this study we investigate the desired level of recovery under various inventory control policies when the success of recovery is probabilistic. All the used and returned items go into a recovery process that is modelled as a single stage operation. The recovery effort is represented by the expected time spent for it. The effect of increasing recovery effort on the success probability together with unit cost of the operation is included by assuming general forms of dependencies. Alternative to recovered items, demand is satisfied by brand-new items. Four inventory control policies that differ in timing of and information used in purchasing decision are proposed. The objective is to find the recovery level together with inventory control parameter that minimize the long-run average total cost. A numerical study covering a wide range of system parameters is carried out. Finally computational results are presented with their managerial implications.     

基于GARCH族模型的深证成指波动特征实证分析

采用GARCH族模型对深证成指总体及分阶段收益率的波动性进行统计拟合分析,指出深证成指的波动具有集聚性、持久性、显著的非对称性效应及阶段性特征。以深证成指价格达到最高点的时间点为分界,将整个样本分成两个阶段:在第一阶段,“利好消息”对深证成指的冲击比同等程度的“利空消息”大;在第二阶段,“利空消息”的冲击比同等程度的“利好消息”大。这说明深证市场具有杠杆效应。

长江经济带生态效率时空格局演化及影响因素研究

文章基于108个城市2004-2014年市级面板数据测度了长江经济带城市生态效率的时空演变格局,综合而言,长江经济带生态效率水平呈现出波动上升态势,长江流域城市生态效率分化特征明显,湖南、湖北和四川等长江上游城市生态效率较高,长江上、中、下游地区城市生态效率依次递减.对生态效率的影响因素研究表明,科技创新显著地提高了长江经济带的生态效率,经济快速增长降低了城市生态效率,意味着转变经济增长方式、加快科技创新是提高城市生态效率的有效途径.研究还发现,产业结构偏离度有利于提高城市生态效率,而产业升级抑制了城市生态效率的增长,意味着产业升级并不是提高城市生态效率的捷径.     

央视地域形象广告的整合营销传播理论分析

地域形象的广告关键词，高度概括该地域的独特资源，传播地域品牌形象。从广告学的整合营销传播理论看，央视播出的各省市地域形象广告，提炼出基于区域现状定位的关键词，配合地域形象视觉识别系统，选择传统媒体与网络媒体双渠道播出平台，进行组合推广，注重与受众的沟通，方便受众获取广告的便利性。但是，也存在地域形象定位浮于表面、形象识别系统层次不清、播出平台分散、不能与时俱进等现象。
