An analysis of information overload with implications for survey design research

Abstract

A laboratory‐type experiment was conducted to examine potential information overload causes and solutions. It was found that both information quantity and information complexity are potential causes of information overload. The experiment results also suggested that information overload problems may be reduced through carefully designed information display patterns. When designing survey questionnaires, attention must be given to potential causes of information overload. Methods of presenting information that ameliorate information overload must also be considered. As demonstrated in this study, survey designs can be tested in controlled, laboratory‐type experiments. The results of these experiments can then be used to improve the design of field survey questionnaires.     

Meanings of leisure among young consumers of a Rio de Janeiro low-income community

This study investigated the meanings attached to leisure by low-income young consumers. In order to achieve this research objective, the study was conducted in a low-income community in the city of Rio de Janeiro. We used semi-structured interviews with community leaders and observation to acquire a preliminary knowledge of the field. We then interviewed 80 young people with ages varying from 15 to 25?years old. The data were treated qualitatively and quantitatively, using cluster analysis. The results showed, as expected, that these consumers have limited resources for leisure activities, due to lack of money, time or both. However, although the subjects recognise leisure as an important part of their lives, they attribute different meanings to it. Also, their understanding of free time and leisure varies somewhat. The findings provide evidence that these consumers' view of leisure, to some extent, resembles a pre-industrial understanding of leisure, associated with time for rest and time with family and friends. The results also permitted the identification of four different clusters, based on the meanings attributed to leisure and free time, individual aspirations and demographic characteristics.     

《资本论》中的低碳经济理论简述——从经济伦理的视角

从《资本论》的人道观看，低碳经济是人类应然且必然的选择，但是经济活动的碳放量并非越低越好，更不是无碳最好，而且低碳经济未必就是人道的经济。从《资本论》的自由观看，经济活动碳放量的高低变化反映了人类自由不断实现的过程，发展现代社会的低碳经济，科技发展是关键，量力而行是基本原则。从《资本论》的正义论看，资本主义制度下高碳经济的高速发展从根本上讲不是源于其制度的正义性而是源于其制度的不正义性。《资本论》对高碳经济的正义审视仍未过时，对建设我国低碳经济的制度保障也不乏现实的启示性。

胜利油田滨二块双低单元综合治理方案及经济评价

在对胜利油田滨二块砂二段油藏的地质特征、注采井网、开发现状进行精细研究的基础上，科学分析了单元双低（采油速度低、采出程度低）的主要原因，提出了一套技术先进的双低治理方案，采用“增量法”进行经济评价表明，该方案不仅技术可行，而且具有较好的经济效益，是低产老油田恢复能力的好办法。     

In Defense of DEFECT

The one-state machine that always defects is the only evolutionarily stable strategy in the machine game that is derived from the prisoners' dilemma, when preferences are lexicographic in complexity. This machine is the only stochastically stable strategy of the machine game when players are restricted to choosing machines with a uniformly bounded complexity.

对复杂经济系统理论的探讨

传统的经济学是建立在静态的、均衡的理论基础上的,现实经济系统中越来越多的现象已无法在这一理论框架下得到合理的解释。复杂性经济理论将复杂性理论引入经济领域,以动态非均衡的复杂性观点来研究经济问题,认为经济系统是一个过程依赖性的、不断演变的有机体,从而使许多经济现象得到了很好的解释。因此,它已不再是对传统经济理论的补充,而是一种更全面的、建立在非均衡基础上的、崭新的经济理论。对它的探索是有意义的。
