We decompose labor productivity growth into components attributable to technological change, technological catch-up, foreign capital deepening, domestic capital deepening, and human capital accumulation, thus separating the effects of foreign and domestic capital deepening on productivity growth and convergence. We apply nonparametric production-frontier methods to a worldwide 1980-2005 panel a...

the issue of water resources and their effect on human life doesn't need any analysis and reasoning. however, such factors as population growth, improved quality of life and development of urbanization along with improved industrial and technological dimensions of human life have necessitated logical and reasonable planning for optimal use of water and water basins of the world. these fact...

Organization of research personnel We should highlight here the efforts that have been made by the Catalan administration to coordinate research. The structure, size, objectives and affiliation of consolidated research groups (CRGs) have not changed significantly since the previous six-year period (see Table 2). Nor has specific financing changed, continuing to be quite modest. These groups hav...

The role of dynamical cosmological Casimir effect to phantom (constant w ) and oscillating universe is discussed. It is shown explicitly that its role is not essential near to Big Rip singularity. However, the account of Casimir fluid makes the scale factor approach to Rip time to be faster. Rip time itself maybe changed too.

if present trends continue, the world in 2000 will be more crowded, more polluted, less stable ecologically, and more vulnerable to disruption than the world we live in now. Serious stresses involving population, resources, and environment are clearly visible ahead. Despite greater material output, the world’s people will be poorer in many ways than they are today. The Global 2000 Report to the...

The value of human biospecimens available for research dramatically increases when linked with their accumulated clinical and molecular (genomic, proteomic, subcellular modeling) data. Further, informatics tools make it possible for researchers (both intra- and inter-institutionally) to locate tissue needed for research faster and more reliably. We are developing a virtual human biospecimen rep...

During the past few years we have experienced the development of several E-Learning systems. Unfortunately, several of these systems fail to satisfy the learners’ needs and requirements due to the absence of key human and technological issues in the engineering process. The successful development of E-Learning systems requires the identification of human issues such as, social and cultural fact...

in the knowledge-based era knowledge management (km) is considered as the primary task of organizations that strive to utilize of their intellectual capitals effectively. hence it is vital to understand carefully the appropriate contexts and enablers of knowledge management practices. human- social factors are among most influential factors that their effects are as important as structural and ...

Given more than seven thousand years of urbanization and highly diverse topographic andgeographical conditions, Iran is one of the treasures through the world's architectural history. Climatic diversity,on the one hand, and long history of living, on the other hand, has led to noteworthy and valuable achievement inarchitecture and urbanization within this country. However, these elements are le...
