Ranking fuzzy numbers is a very important decision-making procedure in decision analysis and applications. The last few decades have seen a large number of approaches investigated for ranking fuzzy numbers, yet some of these approaches are non-intuitive and inconsistent. In 1992, Liou and Wang proposed an approach to rank fuzzy number based a convex combination of the right and the left integral values through an index of optimism. Despite its merits, some shortcomings associated with Liou and Wang's approach include: (i) it cannot differentiate normal and non-normal fuzzy numbers, (ii) it cannot rank effectively the fuzzy numbers that have a compensation of areas, (iii) when the left or right integral values of the fuzzy numbers are zero, the index of optimism has no effect in either the left integral value or the right integral value of the fuzzy number, and (iv) it cannot rank consistently the fuzzy numbers and their images. This paper proposes a revised ranking approach to overcome the shortcomings of Liou and Wang's ranking approach. The proposed ranking approach presents the novel left, right, and total integral values of the fuzzy numbers. The median value ranking approach is further applied to differentiate fuzzy numbers that have the compensation of areas. Finally, several comparative examples and an application for market segment evaluation are given herein to demonstrate the usages and advantages of the proposed ranking method for fuzzy numbers. © 2013 Elsevier B.V.

In 2007 and 2008, international prices of rice and other grains sharply increased, raising fears that poor households in developing countries would become poorer. Yet, these fears often ignored that many of these poor households were food producers. This study examines the impact of rising food prices on welfare in Vietnam. Our results show that, overall, higher food prices raised the average Vietnamese household's welfare. However, higher food prices made most households worse off. Average welfare was found to increase because the average welfare loss of households whose welfare declined (net purchasers) was smaller than the average welfare gain of those whose welfare increased (net sellers).Copyright 2011 Western Agricultural Economics Association.

Electricity has attained a very important place in every household on this planet. It is a major contributor towards improvement of the standard of living of any individual, family and society at large. This paper aims to find out the monthly average household electricity consumption and seasonal variations in this consumption for the months of summer, winter and moderate weather for Delhi. The factors which influence the electricity consumption of a household have been examined by using a questionnaire based study of 395 Delhi households selected via stratified random sampling technique. Multiple regression models have been run to describe the pattern of household electricity consumption. The results from the study show that the stock of appliances in a household contributes the most to the variation in the dependent variable. An inverted U-shaped non-linear Temperature-Electricity Curve has been derived from the primary data used in the study.

The aim of this paper is to describe the patent systems of fast developing ASEAN countries (Indonesia, Malaysia, Philippines, Singapore, Thailand and Vietnam) and understand the factors that drive the demand for patents in these countries. Patent systems in these countries have now been strengthened to a large extent, the number of patent applications has increased substantially, although at a very different pace across countries. The policy features that seem to be associated with a strong increase in demand for patents are: i) policies aiming at attracting FDI; ii) low relative costs (or fees); and iii) a relatively low quality of the examination processes. The significant differences in the patent systems of these fast developing countries echo to some extent the differences observed between the patent systems in Europe, the USA and Japan. © 2012 Elsevier Ltd.

Climate change effects are becoming evident worldwide, but some water scarce regions present higher vulnerability. Spain, located in the Mediterranean region, is expected for instance to be highly vulnerable given its unbalanced distribution between water resources availability and existing demands. This article presents an introduction to the main threats of climate change mainly on water resources, but it also assesses effects in interlinked areas such as agriculture, soil and land management. Contents focus on measures and initiatives promoted by the central government and address efforts to establish multi-sectoral coordinating bodies, specific adaptation plans and measures for the different sectors. The article highlights some political aspects, such as the complexity of involved competent authorities in water and land management, the need to strengthen public participation and the conflicts arising from the defence of regional interests. It also makes a link to current EU policies; summarises foreseeable problems derived from climate change effects, and provides some recommendations in the different areas covered. © 2013 Elsevier B.V.
