Accumulated knowledge about nature is an important part of people's capacityto manage and conserve the environment. But this ecological knowledge is now being increasingly lost. There have been few cross-cultural and quantitative studies to describe the phenomenon of its loss. Here we show a strong inverse correlation between ecological knowledge and income levels in and among India, Indonesia,...

in this paper particle swarm optimization with smart inertia factor (pso-sif) algorithm is proposed to solve combined heat and power economic dispatch (chped) problem. the chped problem is one of the most important problems in power systems and is a challenging non-convex and non-linear optimization problem. the aim of solving chped problem is to determine optimal heat and power of generating u...

In terms of economic development, China is widely acclaimed as a miracle economy. Over a period of rapid economic growth, however, China's reputation for health has been slipping. In the 1970s China was a shining example of health development, but no longer. Government and public concerns about health equity have grown.

The quantitative relationship between higher education and economic growth in the tradition of “growth accounting equations” and also “neoclassical production function” approach have occupied a pride of place in economics of education, particularly the literature on more developed countries. However, production function type models that allow for isolating the “indirect” (external) effects of h...

Background and objectives: The development and distribution of hospital beds, regardless of effective factors, may downgrade equity in access to health services through imposing costs of inefficiency. This study aimed to develop a hospital bed distribution model in Iran in order to facilitate the optimal and cost-effective development and distribution of hospital beds. Methods: This descriptiv...
