There is now abundant scientific evidence that humanity is living unsustainably. The environment is gradually becoming more overstressed. People now are transforming ecosystems throughout the world at a faster and more extensive pace than any other time in human history. We are culturally given...

The data on JIFs provided by Thomson Scientific can only be considered as a sample since they do not cover the entire universe of those documents that cite an intellectual output (paper, article, etc) or are cited by others. Then, questions arise if the empirical distribution (best fit to the...

Ever-increasing population and ever-proliferating demand for variety and choice together with a marked preference in favor of deliberate under-utilization of resources as well as deprecation of thrift have exposed the available reserves of natural resources to the danger of depletion. The...

Is journal impact factor a good measure of research merit? This question has assumed a great importance after the notification of the University Grants Commission (Minimum Qualifications for Appointment of Teachers and other Academic Staff in Universities and Colleges and Measures for the...

Structural change which is inherent in an evolving economy refers to a long-term widespread transformation of the fundamental relationships among different parts and organic constituents of it, rather than micro scale or short-term change in output and employment. Short-term economic challenges...

In this paper an attempt has been made to fit the Gielis curves (modified by various functions) to simulated data. The estimation has been done by two methods of simulated annealing - the Classical Simulated Annealing (CSA) of Kirkpatrick et al. and the Generalized Simulated Annealing (GSA) of...
