The economics of the satisfaction of needs
This paper is a proposal for the development of an econ­ omics that would be based on satisfaction of the unvarying and universal human needs and not of desires or wants, which are easily manipulable and change, not only from one society to another, but also from one individual to another and even for the same individual at different moments of his or her life. This economics would deal with the production, distribu tion, and use or consumption of all those entities goods, services, relations, self-expressions - that satisfy human needs. It is suggested that in order to achieve stability in social and economic growth, all needs should be simultaneously satisfied, not only the so-called basic needs - food, shelter, clothing, health care, and education. It is claimed that tech­ nological development is making this proposal possible, parti­ cularly because the satisfaction of most of the psychological and sociocultural needs relies mainly on gratuitous relations
The effect of different needs, decisionmaking processes and networkstructures on investor behavior and stock market dynamics : a simulation approach
Striking investor and stock market behaviour have been recurrent items in the worldwide press for the recent past. Crashes and hypes like the Internet bubble are often hard to explain using existing finance frameworks. Therefore, the authors provide a complementing multitheoretical framework that is built on existing finance research to describe and explain investor?s behaviour and stock market dynamics. This framework is built on three main components: needs, decision making theory, and (social) network effects. This framework will be used to build a future simulation model of investor behaviour and to generate stock market dynamics. A brief outline of the design of these simulation experiments will be given.
Fluid to liquid membrane energy exchanger for simultaneous liquid desiccant regeneration and desalination applications–Theoretical and experimental analyses
Abstract In this paper, a thermal model developed for assessing the performance of the fluid to liquid membrane energy exchanger based liquid desiccant regenerator is presented. The model was validated with the experimental data and found accurate. Using the experimental inlet conditions reported in the literature for the structured packing chamber, the performance of the fluid to liquid membrane energy exchanger based liquid desiccant regenerator was theoretically predicted choosing water and air as working fluids and Lithium Chloride as a liquid desiccant. Further, studied the influence of inlet parameters such as working fluid and desiccant inlet temperature’s, hot liquid desiccant to cold working fluid ratio and desiccant concentration on vapour absorption rate. From this analysis, it is observed that membrane based liquid desiccant regenerator using water as a working fluid is best suitable for converting the weak desiccant into strong desiccant and for generating the pure water simultaneously (co-generation process). An experimental investigation was carried out for assessing the energy exchange process across the membrane based liquid desiccant regenerator using water as a working fluid. From the experimental analysis, it was found that desiccant temperature has a significant impact on the energy exchange process. The pressure drop across the membrane based liquid desiccant regenerator was also measured at different desiccant flow rates and concentration.
