In 2007, the social networking web site MySpace apparently overthrew Google as the most visited web site for U.S. web users. If this heralds a new era of widespread online social networking, then it is important to investigate user behaviour and attributes. Although there has been some research into social networking already, basic demographic data is essential to set previous results in a wide...

For submanifolds tangent to the structure vector field in Sasakian space forms, we establish a Chen’s basic inequality between the main intrinsic invariants of the submanifold namely, its pseudosectional curvature and pseudosectional curvature on one side and the main extrinsic invariant namely, squared pseudomean curvature on the other side with respect to the TanakaWebster connection. Moreove...

The value of customer participation has been emphasized in order to improve the information exchanging between customers and companies. Value co-creation is one of the most important ways to achieve that goal; an...

In [1], Z. Chen proved that, if for each terminal condition ξ, the solution of the BSDE associated to the standard parameter (ξ, g1) is equal at time t = 0 to the solution of the BSDE associated to (ξ, g2) then we must have g1 ≡ g2. This result yields a natural question: what happens in the case of an inequality in place of an equality? In this paper, we try to investigate this question and we ...
