— This paper defends the wisdom of not considering the Digital Economy to be one homogeneous sector. Our hypothesis is that it is best to consider it the result of adding four different subsectors. We test whether indeed the economic and financial performance of a portfolio of listed companies in each of the four subsectors presents relevant differences. We use the value at risk measure to esti...

Even within these regions, however, there is considerable variation across countries, which is sometimes an artifact of very different definitions of ‘rural’ . The one safe generalization is that the non-farm sector is heterogeneous. This component of the rural economy comprises a wide spectrum of activities and institutional forms, and is often linked in complex ways to country-specific agricu...

We calculate the one–loop corrections to gauge couplings in N=1 supersymmetric brane world models, which are realized in an type IIA orbifold/orientifold background with several stacks of D6 branes wrapped on 3–cycles with non–vanishing intersections. Contributions arise from both N=1 and N=2 open string subsectors. In contrast to what is known from ordinary orbifold theories, N=1 subsectors do...

the main objective of this study is to examine the impacts of two demand side policies, namely; expanding food industries and externally increase in households’ demand for agricultural goods ,on the growth of products in agricultural subsector. to this end, a social accounting matrix (sam) is constructed based on the latest iranian input- output table released in 2001. then, production multipli...

In recent times, many countries, particularly in Sub-Saharan Africa and Southeast Asia, have been left puzzled by their failure to improve nutritional outcomes despite prolonged periods of rapid economic growth, in some cases accompanied by rising incomes among the poor. The Tanzanian economy is one example of a country that failed to reap the benefits of sustained rapid growth. National gross ...

We show agreements, at one-loop level of field theory, between energies of semiclassical string states on AdS 5 ×S 5 /Z M and anomalous dimensions of operators in N = 0, 1, 2 orbifold field theories originating from N = 4 SYM. On field theory side, one-loop anomalous dimension matrices can be regarded as Hamiltonians of spin chains with twisted boundary conditions. These are solvable by Bethe a...

Random Matrix Theory (RMT) and the decomposition of correlation matrix method are employed to analyze spatial structure of stocks interactions and collective behavior in the Shanghai and Shenzhen stock markets in China. The result shows that there exists prominent sector structures, with subsectors including the Real Estate (RE), Commercial Banks (CB), Pharmaceuticals (PH), Distillers&Vintners ...
