This paper analyzes the quality of life over time in the U.S. In this paper we propose a statistical cluster analysis method based on an informationbased measure. This method is then employed to cluster diverse attributes of the quality of life. Aggregate annual measures of welfare are computed...

Using ARIMA models and entropy, the dynamic evolution of several functions of aggregate income and other attributes of well-being is analyzed for statistical "similarity" in order to determine potentially distinct dimensions in multidimensional analysis of welfare and quality of life in the US....

This paper considers the similarity between two measures of air pollution/quality control, on the one hand, and widely used indicators of life quality and welfare in the US, on the other. We use statistical cluster analysis based on information measures of similarity and distance. The results...

A transformed metric entropy measure of dependence is studied which satisfies many desirable properties, including being a proper measure of distance. It is capable of good performance in identifying dependence even in possibly nonlinear time series, and is applicable for both continuous and...

A quick and efficient portable solar steriliser development prototype has been tested successfully in the laboratory. With field development, the technology may offer a cost-effective alternative to disposable syringes and has a second function in the sterilisation of surgical equipment. Several...

The creation of an innovation niche depends on the interaction of three mechanisms involving: converging expectations, networking among the innovation actors, and learning about the novelty through efficient knowledge creation and diffusion. Such mechanisms define the key characteristics of a...

Canada’s IPY program funded seven marine projects spanning the North American Arctic. Work embraced oceanography, air-sea interactions, storm response, paleo-climate and trace-element chemistry. Notable findings are emerging. Conditions in the Beaufort were unusual in 2007, with very high air...

This paper examines the neo-liberal development strategies adopted by Central America and the Caribbean during the 1980s and 1990s. The historical pattern of CAC trade and a general discussion on trade liberalization are coupled with 3 specific case studies - Costa Rica, Guatemala and Jamaica -...

Predictions, as made in Leach et al. (A low-energy strategy for the United Kingdom. Science Reviews Ltd., Austria: International Institute for Environment and Development, 1979.) have been compared with actual values for subsequent years. Their disparities are discussed, together with the...
