and Applied Analysis 3 Theorem 1.1. Let n0, p0 ∈ L1 R2 ∩ L logL R2 , n0, p0 ≥ 0 in R2, ∫ n0 dx ∫ p0 dx,∇φ0 ∈ L2, and u0 ∈ L2. Then there exists a unique weak solution u, n, p, φ to the problem 1.1 – 1.6 satisfying ( n, p ) ∈ L∞0, T ;L1 ∩ L logL ∩ L20, T ;L2 ∩ L4/30, T ;W1,4/3, n, p ≥ 0 in R2 × 0, T ( ∂tn, ∂tp ) ∈ L4/30, T ;W−1,4/3, ∇φ ∈ L∞0, T ;L2 ∩ L20, T ;H1 ∩ L40, T ;L4, u ∈ L∞0, T ;L2 ∩ L20...

This study investigates the relationship of strategic leadership behaviors with executive innovation influence and the moderating effects of top management team (TMT)’s tenure heterogeneity and social culture on that relationship. Using survey data from six countries comprising three social cultures, strategic leadership behaviors were found to have a strong positive relationship with executive...

1. P. 74. Substitute the last seven lines by: There exists a unique gradient ̃ ∈ L2 (P0) with smallest L2 (P0)-norm such that ̇ = ̃ + (̇ − ̃) and (̇ − ̃) is orthogonal with respect to {g− h : g; h ∈ T (P0;P)}. Actually, ̃ is the orthogonal projection of ̇ on the L2 (P0)-closure of the latter space. 2. In Theorem 3(b), Corollary 3.3, and A(ii), p. 78 the following assumption is needed (which triv...

Expression of myelin proteins has been shown to be altered in transgenic mice that express papovaviral large tumor (T) antigens. This paper analyzes the effect on P0 gene expression in secondary Schwann cells transfected with the SV40 T antigen gene and in Schwann cells immortalized by T antigen. In secondary Schwann cells, both T antigen and c-Jun are required for significant inhibition of the...
