Using model selection techniques based on out-of-sample predictive ability criterion in a Vector Autoregression (VAR) framework, this paper empirically examines the causal relations among growth, trade, and wage inequality in Bangladesh between 1971 and 2000. There is some evidence of bi-directional causality between growth and inequality and between trade and growth. That growth causes trade a...

irrigular land use, land degradation and increasing yield per surface area unit supplicate to be inevitable optimal land utilization.so land evaluation, planning and management to be necessary to achieve a sustainabledevelopment.following this trend, microleis (mediterranean land evaluation information system)has evolved towards an agro-ecological decision support system.the goal of this study ...

LCA is an environmental management tool for assessing the comprehensive environmental impacts of products, processes and activities. Assessment is undertaken along the life cycle from extraction of raw materials, through processing, manufacturing, transportation, use and on to final disposal. This is illustrated by reference to a study of breadmaking wheat production where the relative environm...

There are substantial differences in the relative size of tax bases across counties in Georgia. These differences mean that the ability or capacity to raise revenue differs across the State. For example, counties with large property tax bases per capita, i.e., those with large manufacturing facilities or power plants, have greater revenue raising potential than purely agricultural counties. Thi...

This study examines technology use in Canada’s manufacturing sector, and how a set of technology-using manufacturing establishments performed relative to non-users. Data originates from a recent Statistics Canada survey, asking manufacturing firms about their use of 22 advanced manufacturing technologies, and panel data taken from the Census of Manufacturers. Results show that the use of advanc...

Squeeze film dampers (SFDs) are often used in machines with high rotational speed to reduce non-periodic behavior by creating external damping. There are some structural parameters which are of great importance in designing these systems, such as oil film thickness and inner race mass of SFD. Moreover, there is a crucial parameter associated with manufacturing process, under the title of wavine...

Agent based modeling and simulation consider the behavior of agents acting in a system. The agents' interactions result in changing the agent’s behavior, the whole agent based system, and its environment. In this study, the manufacturing, sale, and receiving orders behaviors pertinent to manufacturing and sale agents acting across a pharmaceutical supply chain of an Iranian manufacturing medici...
