Which survey indicators are useful for monitoring consumption? Evidence from European countries

This paper assesses the information content of two survey indicators for consumption developments in the near future for eight European countries in the period 1985–1998. Empirical work on this topic typically focuses on consumer confidence, the perceptions of buyers of consumption goods. This paper examines whether perceptions of sellers of consumption goods, measured by retail trade surveys, may also improve short‐term monitoring of consumption. We find that both consumer confidence and retailer confidence embody valuable information, when analysed in isolation. For France, Italy and Spain we conclude that adding retail confidence does not improve the indicator model once consumer confidence has been included. For the UK the reverse case is obtained. For the remaining four countries we show that combining consumer sentiment and retail trade confidence into a composite indicator leads to optimal results. Our results suggest that incorporating information from retail trade surveys may offer significant benefits for the analysis of short‐term prospects of consumption.

The behavior of the homozygous and heterozygous sub-types of rats which are genetically-selected for diabetes insipidus: A comparison with Long Evans and Wistar stocks

Several aspects of spontaneous and conditioned behavior (food and water intake, locomotion and emotionality, passive and active avoidance acquisition and retention) of standard (albino and pigmented) rats, and rats heterozygous (HEDI) and homozygous (HODI) for diabetes insipidus, are reviewed. As would be expected, HODI rats have been repeatedly found to consume far more fluid than either HEDI or control rats. Pigmented rats appear to be more active than albinos. HODI rats exhibit less marked emotional responses than do control rats, among which the pigmented ones exhibit the highest emotionality. Light aversion is more evident in albino than in pigmented rats. No differences are found among HEDI, HODI and normal Long Evans rats. It is quite difficult to provide a clear-cut statement concerning inter-strain differences in passive avoidance behavior, possibly because of the variety of techniques employed. In any case, HODI rats do not perform worse than normal controls do. In one-way active avoidance paradigms, pigmented rats perform better than albinos, and the performance of HODI rats does not differ from that of controls. In two-way avoidance paradigms, albinos appear to outperform pigmented rats. Once again, there are no obvious differences between HODI and control animals.In addition to indicating that HODI rats may actually be less emotional than the other groups of rats reviewed here, the studies described once again fail to confirm the previously alleged functions of vasopressin in memory consolidation.

快乐、广义消费与和谐社会模式的建构

快乐是人类经济社会发展惟一有惊天动地性的终极目的。而满足人类快乐需要的不仅是人类创造的国民财富，自然环境中的蓝天白云、青山绿水同样构成人类广义消费的基础内容，成为人类无上快乐的源泉。因此，广大科技工作者应确立科学发展观，在失去科学技术进步、实话国家重大工程与技术项目过程中，关注、构造人与自然和谐发展的经济社会模式。这对全面建设小康社会、实现人类快乐具有深远的意义。

鲁西北地区农民商业保险消费滞后的原因与解决对策

针对当前经济社会改革过程中农民生活的风险含量不断增大的事实,主要考证农业地区商业保险在农民规避风险中所起的作用,发现商业保险介入农民生活的力度还不强,由此分析其原因,并给出解决的对策。之所以选择鲁西北地区作为研究样本,是因为该地区农民以农业生产为主,属经济欠发达地区,与我国大部分农业地区的经济发展情况大体相当,对研究以农业生产为主的农村地区农民的保险消费情况具有一定的代表性。
