Spatial spillover of global value chain in eco-efficiency

eco trade potential: the application of dynamic spatial regression by considering spatial spillover effects

regional agreements can facilitate the integration of world economies by opening the borders to the trade development while accelerating technological changes and maintaining the economic growth. trade potential is defined as the trade that could be achieved at an optimum trade frontier with the open and frictionless trade possible through regional agreements based on the current level of trade...

Eco-Efficiency in Corporate Budgeting

The efficiency and eco-efficiency of manufacturing

In this paper, we review the efficiency of both manufacturing processes and systems over recent decades and compare nano-materials technologies in this context. To a first approximation, nano-materials processes appear to be about as efficient as semi-conductor processes. That is, their second law efficiencies are of the order 10, while conventional processes are of order 10. However, many of t...

Identification of the effective factors on the efficiency of the production section of the value chain of tuna in Iran

This paper attempted to identify the effective factors and barriers on efficiency of the production section (canning and processing) the value chain of tuna and tuna like species in Iran. The present research is practical in terms of purpose and it is descriptive and survey in terms of collecting data. The statistical population of this research was board members, executive directors, the pr...

Phenology supports the eco-environmental hypothesis for Ebola spillover events

Ebola virus disease outbreaks in mammals (including humans and great apes) start with sporadic host switches from unknown reservoir species. The factors leading to such spillover events are not clearly understood. Filoviridae have a wide range of natural hosts and are unstable once outside hosts. Spillover events, which involve the physical transfer of viral particles across species, could ther...
