It is a problem that logistics development neglects the trade or commerce. The trade flow guides the logistics. So the logistics should develop calmly. If not, it might cause the problem of irrational and aimless resources allocation.展开更多

This paper firstly clarifies the definition of REM and regards that REM differs essentially from Rational Economic Man. Subsequently, the.paper analyzes the signi＇ficance of establishing REM to construct the harmonious society. Finally, the paper provides some specific suggestions on how to establish REM.展开更多

It is often given in the standard parametric form, but it can also be in the implicit form which is commonly used in algebraic geometry. Not all algebraic developable surfaces have rational parametrizations. In this paper, the authors focus on the rational developable surfaces. For a given algebraic surface, the authors first determine whether it is developable by geometric inspection, and then give a rational proper parametrization in the affrmative case. For a rational parametric surface, the authors also determine the developability and give a proper reparametrization for the developable surface.展开更多

This paper explored the performance of various institutions regarding execution of watershed development programmes in semi-arid region of India. Recorded observations from documents maintained at watershed level and information collected through primary survey as well as focus group discussion with different types of stakeholders were used for analysis. The results indicated lacunae in participatory aspects during programme implementation process like monitoring activities, management of common property resources and equity. Gap in linkages and differential level of performance of various watershed level functionaries indicates the necessity for corrections in the structures and linkages pattern for sustainability of the infrastructure and institutions. The study also showed unequal priorities by the implementing agencies towards in-stitutions, land and water resources development, production enhancement activities and fodder re-sources development as well as rationalities of technical, economic, financial, political and social aspects among the watersheds.展开更多
