developing an integrated model, establishing a balance between conservation and revitalization objectives in the historic environment, has always been a controversial issue in many countries; however, they sometimes have a type of symbiotic relationship with each other. in this regard, the main aim of this paper is to answer this question: is it possible to provide an appropriate model for “int...

climate change is a complicated issue with many factors playing role in its formation and distribution. considering this complication, a comprehensive and holistic approach is needed for a better understanding and management of those factors. the causal frameworks are among systemic and integrated methods for addressing the causes of environmental problems and the relationships that exist betwe...

An analytically tractable approximation of a numerical model is used to investigate coalition formation between nine major world regions with regard to their policies for greenhouse gas emission reduction. Full cooperation is not individually rational. Assuming non-transferable utility, side payments do not ensure full cooperation either. Without side payments, the largest stable coalitions are...

We introduce endogenous directed technical change into numerical integrated climate and development policy assessment. We distinguish expenditures on innovation (R&D) and imitation (international technology spillovers) and consider the role of capital investment in creating and implementing new technologies. Our main contribution is to calibrate and numerically solve the model and to examine th...

The challenge of integrated assessment is the integration of scientific and social aspects for the preparation of decisions. On one hand it is necessary to find scientific and technologically sound solutions, on the other hand the results should meet the interests of social groups affected by the particular project. In large projects it is also necessary to consider the effects on sustainable d...

one of the main objectives of quantitative researches is assessment of models developed by qualitative studies. models validation through their testing implies that the designed model is representative of the existed facts. hence, this study was conducted to assess the clinical nurses' productivity model presented for iranian nurses' productivity. the sample of the study consisted of 360 nurses...
