The Study of Nonlinear Effects of Government Size on Happiness in Developing and Developed Countries by the Threshold Approach

Expended Abstract Introduction: One of the most important goals of today’s societies is to achieve a happy society, a society where the happiness of its people will improve the quality of life and labor productivity, will boost economic growth and, ultimately, will lead to sustainable development. In this regard, government expenditures and the amount of government intervention in the econom...

Investigating the Effect of Land Use and Soil’s Physio-chemical properties on Wind Erosion Threshold Velocities via Data Mining

Introduction: Wind erosion is a phenomenon that causes severe environmental changes in arid and semi-arid climates. As surface soil texture is very effective in soil erodibility, identifying soil erodibility index is important and efficient. Mismanagement greatly contributes to the development of wind erosion. The velocity that makes the first particles of soil move from the surface is called t...
